The technical field to which the invention relates

The present invention relates to absorbent body, which is used for absorbent articles such as sanitary pads, disposable diapers and briefs used in case of incontinence, and to absorbent product in which the absorbent body.

Prior art

Absorbent product, which is used for sanitary napkins, disposable diapers and the like, generally has an absorbent body that absorbs and retains the liquid or the like between permeable to liquids top sheet which is located on the side of the skin, and not permeable to liquids back sheet which is located on the side of the garment. The absorbent body usually has approximately a rectangular shape that covers the place of excretion in the host, and it was suggested that the absorbent body having an improved form and structure.

For example, in patent literature 1 source revealed the flat type diaper containing an absorbent body with such size that provides substantially closing full front and rear zones excretion from the gluteal area to the abdominal area, the entire one side surface of the absorbance�youseo body attached to the outer sheet, and many narrow areas with grooves, which are parallel in the center of the absorbent body. In this diaper fibrous elastic element is orthogonal to the parallel direction of the narrow sections with recesses in the above-mentioned absorbent body, resulting in narrow areas with indentations deformed to open and close while wearing to give some stretch and the ability to flexion of the entire absorbent body. However, this absorbent body is composed of many independent absorbent elements. Since all large absorbent body is fixed to the sheet, the diaper is not so different from conventional diapers in this place, and, therefore, it is impossible to expect a significant improvement in prelevement to the body and the ability to follow the shape of the body during movement.

In patent literature 2 is disclosed the absorbent pad, which is not permeable to liquids back sheet and the permeable for liquids covering sheet connected to each other by lines, forming a lattice configuration in the form of rhombuses (type lattice Narihira). The main part of the absorbent material is located in the closed position in each of the rhombic areas surrounded by a connection line. It is believed that the connection lines forming a lattice p�amoralnoe form in which the above-mentioned absorbent material is missing, form a channel for the passage of water, and the liquid can take place in it. However, the entire surface of the main part of the above-mentioned absorbent material is attached to is not permeable to liquids rear sheet, and thus also difficult to expect a significant improvement in prelevement to the body and the ability to follow the shape of the body when the body moves. In addition, connection lines, forming a lattice, which form the above-mentioned channel for the passage of water, but rather may lead to the presence of residual fluid or may constitute a barrier element with respect to the movement of fluid between the zones of the ethmoid forms depending on the purpose of application and condition of the feces.

In the products described in patent literature source 3, many rectangular absorbent bodies arranged in any order in parallel so that their longitudinal directions are oriented in the same direction on a stretchable sheet, and one longitudinal side of each absorbent body is fixed on a stretchable sheet by adhesion. Appropriate absorbent body are arranged so that they overlap with each other in the width direction, and connected by sufficiently covered�I, the overlap of the absorbent bodies is maintained even when stretching sheet, stretchable. As each arranged in the form of a table of absorbent bodies mounted on a stretchable sheet only on one longitudinal side, the elongation in the direction orthogonal to the longitudinal direction, is provided to a greater extent than in the case where the totality of absorbent bodies, which covers the entire area of the base sheet attached to the entire surface. However, the ability to stretch in the direction of the longitudinal side is not improving and is not different from the corresponding capacity of conventional products. The same is true regarding the ability to bend, and it is impossible to provide a complex deformation.

In patent literature 4 discloses an article with an absorbent body which is formed from a composite sheet consisting of a laminate layer of nonwoven material and a layer of fibrous canvas as the top sheet and the absorbent body. An example of a composite sheet comprises: a first mesh area in the form having the form of a lattice-like belt zones in plan view, which has a high density and a small thickness, and a second mesh area in the form of rectangular areas separated by the above-mentioned lattice zones, which has �low density and a large thickness. The above-mentioned first mesh area is formed in the form of a zone having a higher density compared to the density of the second mesh area, by bonding the fibrous bulk of the canvas with a layer of nonwoven material in this zone together with compression. Namely, the fibers of the nonwoven material are flat by a strangled condition in the first mesh area. However, fibrous canvas is located on the layer of nonwoven material on the entire surface of this composite sheet, and thus, the surface density (mass of 1 m2in General, not ranges, and the composite sheet is not divided. Therefore, improving the ability to stretch, prelevement and the ability to follow the shape of the body during movement is very limited.

Description of embodiments of

Further, the present invention is described in detail with reference to the drawings based on the preferred options of its implementation.

(The first variant of implementation)

Fig.1 is performed with a partial broken-out section view in perspective absorbent article (sanitary napkin) 100, which uses an absorbent body in accordance with the first variant implementation of the present invention, and Fig.2 is a section made according to line II-II in Fig.1. The absorbent body 10 according to this embodiment of the contains stretchable base sheet 2 and a number of independent absorbing elements 3, which are arranged on the surface (upper surface) of the support 2 in the longitudinal and transverse directions so that between them there are defined gaps d and e in a natural state. Absorbent �element is provided 3 is rectangular in plan view and is a relief trapezius body and has the shape of a slightly rounded truncated square pyramid (truncated pyramid) on the surface of the section. However, the shape is not limited in a particular way in this embodiment, the implementation, and can be taken in any form. In this embodiment of the absorbent element 3 is composed of cellulose fibers and polymers with ultra-high absorbing ability, and their contours are not necessarily standard form, similar illustrated, and preferably have a spatial form in General, as mentioned above.

The absorbent element 3 has a trapezoidal shape in cross section, and the area of the upper surface 3A is slightly smaller than the area of the lower surface 3b. In addition, if we consider the surface element in cross section, it is seen that the side 3C tilted (skewed) towards the bottom surface to extend toward the end. Each absorbent element 3 portion of the lower surface rather than the entire lower surface, in particular, the locking element 4, which is located in the area of the absorbent element in plan view (see the Central part t of the lower surface 3b on the enlarged view of Fig.2) fixed on the base sheet 2. In other words, in the case where a projected image of the absorbing element 3 and the fixing element 4 is projected in the direction of the thickness of the absorbent body, such a mutual arrangement in which a projected image�agenie the locking element 4 is "surrounded" projected the image of the absorbent element 3. The locking element 4 is constructed so that it has the ability to stretch. The locking element 4 can be formed, for example, by ultrasonic embossing, thus in this part of the base sheet 2 will be deprived of the ability to stretch. In an alternative embodiment, the locking element 4 can be formed by hot-melt bezrastvornogo adhesive or the like. In this case, in order to make the attachment between the absorbent element 3 and the base sheet 2 in the area of the retaining element is more durable and more stable, pressure can be applied through the use of the rod from the face the skin surface 3A of the absorbing element 3. Upon application of pressure through the use of the rod in the center absorbent element according to this variant of implementation (see Fig.1) formed part of the 3k with a pole. As part of 3k with the hole acquires a high density, between the part with 3k fossa and the other part forms a gradient from the denser parts for less dense, causing the liquid is readily absorbed in the center, and thus the absorptive capacity improves. In addition, the lower surface 3b of the absorbing element 3 is in a state in which it is not glued to the base sheet on the outside of the locking element 4, resulting WHA� the ability of the base sheet 2 to the stretching is stored in the external lateral area s, which corresponds to the bottom surface 3b.

As mentioned above, since the portion attached to the base sheet 2, represents only the t zone, which corresponds to only the locking element 4, the stretching of the base sheet has little effect on the shape and function of each absorbent element 3, and may be provided with a stable absorbent capacity when using. On the other hand, from the point of view of the functioning of the base sheet does not excessively restrict the movement of the base sheet, as appropriate absorbent elements 3 are, independently, as mentioned above, and the entire base sheet 2 can stretch and bend extremely flexible. The result is guaranteed deformability of the entire absorbent body during movement of the carrier, and, in addition, in accordance with this variant implementation of the absorbent element 3 to allow the fluid flow to pass between them while stretching and bending, whereby, as will be discussed below, a highly absorbent capacity can be maintained while wearing.

In particular, for example, when the sanitary towel 100 shown in Fig.1, extends in the longitudinal direction, the absorbent element 3, 3, 3 ... more separated from each other in the longitudinal direction, it eats� the interval d increases. On the other hand, the size of the sanitary napkin 100 in the width direction is reduced, as if she were shrinking, and the interval e becomes smaller. Thus, the absorbent element 3, 3, 3 ... retain coordination to transfer liquid or the like to each other during deformation of the entire absorbent body 10, whereby they demonstrate good preservation ability to the absorption of fluids or the like. In the present invention, the expression "flow of fluids" means that when the application of the tensile force to the absorbent body of the absorbent elements approach each other or contact with each other and are in a state in which the liquid or the like can be moved between the absorbent elements. Despite the fact that the distances (gaps d and e) between the absorbent element in a state where such tensile force is applied, is not limited in a particular way, the distance is preferably approximately from 0 to 30 mm, more preferably approximately from 0 to 10 mm under a normal tensile force (for example, 100 mV/25 mm) that occurs while wearing. In addition, even more preferably, the distance was approximately 0 to 5 mm.

In particular, since the absorbent body 10 on this VA�Ianto implementation are formed by the Union of many small independent absorbent element, "the ability to fit the body while ensuring that the waviness (undulations) of the surface of the skin is significantly increased compared with the corresponding ability of a conventional absorbent bodies. in addition, since the absorbent body exactly the same shape of the body during movement of the carrier, it has an extremely high ability to follow the shape of the body during movement, thereby preventing the formation of a partial gap at the skin and the like. Under this option the implementation of such good deformability and good retention of absorbed liquids or the like, which are not affected by the deformation, can be provided simultaneously.

In addition, since in this embodiment, the implementation of many small absorber elements, which are, as mentioned above, arranged on the base sheet in a special way, the absorbent elements are also preferably attached to the surface of the skin, which is extremely difficult curved shape. For example, after the application of sanitary pads from the place of excretion to the gluteal area, it bends in the longitudinal direction in accordance with the roundness of the buttocks. However, conventional absorbent body which is enclosed in this strip, usually has a significantly higher stiffness compared � stiffness of the other elements, and thus, sometimes there is a swelling of the absorbent body. Due to this buckling deformation of the inner absorbent body with easily placed in buttock cracks, and sometimes it formed a large gap. Namely, it is difficult to simultaneously ensure buckling in the longitudinal direction and bending in the width direction, and thus, it is difficult to ensure sufficient adhesion. Therefore, menstrual blood or the like easily moves through the space formed in the buttock cracks, leaks backward during sleep.

On the other hand, hygienic seal, which is used for an absorbent body according to this embodiment of the smoothly bent and adjacent to the roundness of the buttocks, and accordingly is included in the buttock slit and adjacent to the surface buttock folds, that is, deformed with the formation of the form of the so-called saddle surface or shape of a hyperbolic paraboloid to fit to buttock crease with the formation of a small gap. Therefore, ensure good conformability, i.e. hygiene strip is in close contact with the skin surface of the carrier from the area near the place of excretion to the gluteal area almost without any small gap.In addition, since the strip follows the movement of the skin surface when the carrier rolls or goes, the gap is not formed remains a good fit.

In addition, since the sanitary towel according to this variant implementation has an extremely good ability to recover form, for example, when bending the strip three times or the like in a different package, the fold line formed when doing this, almost does not remain, and thus, the above-mentioned good conformability to the body and the ability to follow the shape of the body motion can be ensured from the start wearing.

In the absorbent body 10 according to this embodiment of the absorbent elements 3 are staggered. In this embodiment of the arrangement in staggered means the location at which the rows of the plurality of absorbent elements are arranged in parallel and steps with which the absorbent elements are arranged in adjacent rows offset relative to each other. In other words, the location is a location at which when projected absorbent element 3 from a certain row in the direction orthogonal projected image will not match the projected images of the absorbent element 3 adjacent to the above�tion next. When explaining a specific example with reference to Fig.7 you can specify that the number And the absorbent element is adjacent to the next In an absorbent element and a parallel row of absorbent elements which extends in the longitudinal direction (direction X), and the rows are repeated with alternating. The auxiliary lines tbthat continue from the center rows of absorbent elements in plan view in a direction orthogonal to the direction (the Y direction), which extend In the ranks of absorbent elements are imaginary. On the other hand, a similar auxiliary lines tain the ranks And auxiliary elements are imaginary. The auxiliary lines taand the auxiliary lines tbare arranged so that they are shifted by a half pitch relative to each other, i.e. so that the intervals between the auxiliary lines taand auxiliary lines tbgenerally equal, with the formation of the array in a checkerboard pattern. Examples of the modified example of this embodiment may include, for example, an implementation option, in which the rows And absorbent elements and rows In the absorbent elements are arranged in the width direction (Y direction) so as to ensure the displacement of the auxiliary lines extending in the longitudinal direction�AI (X direction), in which direction, where the offset steps, rotated by 90º. In addition, if we compare the location is staggered with stone walls, it can be called ordinary brickwork, and examples of its modified examples may include diagonal stonework, masonry, herringbone pattern, hexagonal clutch and the like.

Sanitary gasket 100 according to this embodiment of the (see Fig.1 and 2), as mentioned above, the absorbent body 10 that contains the base sheet 2 and many absorbing elements 3, which are arranged on it, is located on the rear sheet 7, and they are bonded together, for example by hot-melt bezrastvornogo glue, which is applied in a spiral. In addition, the side sheets 8 is fixed on the back sheet 7 in both side parts in the longitudinal direction of the back sheet by hot adhesive bonding or heat sealing, and the inner sides of the upper sheet 1 is held between and fixed them. In this case, the entire peripheral edge of g strip is fixed by heat sealing or the like, so that there is no leakage fenced components of the absorbent body, the fluid that has been absorbed, and the like. Top sheet 1 is located on the absorbent body 10 so that it covers almost the entire surface of the absorbent body 10 and the groove 11, having to�tour in the shape of a cloud with the form of the plan, formed from the top sheet 1 to absorbent body 10 by means of stamping to exclude the incorrect orientation of the upper sheet 1 and the absorbent body 10 (the groove 11 is not illustrated in Fig.2). The upper side of the sheet 1 to be entering into contact with the skin, and the rear side of the sheet 7 to be entering into contact with the undergarment.

Fig.3 is a schematic partial plane view of the absorbent body in accordance with the first variant implementation of the present invention, wherein view (a) on the same drawing shows the state of the absorbent body 10 before deformation and (b) on the same drawing shows the state where the absorbent body is elongated in the longitudinal direction to ensure deformation. Although the base sheet of absorbent elements may be pinched or twisted, this is not shown in Fig.3(b). In addition, on the same drawing fossa 3k not shown, and the clamping elements 4 are shown by dashed lines.

Fig.3 shows the location of the absorbent element 3, wherein the absorbent elements 3, which are adjacent to each other in the transverse direction (Y direction), are arranged with pausegame P2, "offset" on the steps of the P1in the longitudinal direction (X direction). When wearing the absorbent article (not shown, containing such absorbent body 10, the base sheet 2 is sometimes deformed by twisting or deflection caused by a tensile force applied in the longitudinal direction of the absorbent body 10. Due to this deformation caused by the twisting, the gaps between the absorbing elements 3, which are arranged next to each other in the transverse direction (Y direction) decreases, and the absorbent element 3 close to each other in the transverse direction, and the liquid on the absorbent body 10 can be moved through the space between adjacent absorbent members 3 in the transverse direction, as shown by the arrows in Fig.3(b). Consequently, the liquid is in a state in which it can be moved to the space between adjacent absorbent element 3, resulting in a mesh of interconnecting fluid components.

Since in this embodiment, the implementation of each of the absorbent element 3 is fixed to the base sheet 2 only by means of the Central locking element 4 in the plan view, as mentioned above, the flat shape of the totality of the absorbent element 3 is almost not influenced even by twisting or deflection of the absorbent body 10. In addition, the ability of the absorbent body 10 to the absorption of liquids is almost not reduced, and the guarantor�induces stable absorptive capacity and the ability to move fluid while wearing to above the expected fluid flow. The direction and the position of "inclusion" in the absorbent product may also be determined appropriately taking into account the direction in which to pass the expected flow of fluid, and the like during such elongation. The size of the absorbent element 3 in a variant implementation 1 of Fig.1 width T in the transverse direction as an example, is preferably from 1 to 50 mm, more preferably from 2 to 30 mm, whereas the use of absorbent element in sanitary napkins, but the size varies slightly depending on the absorbent product, in which it needs to be enabled. Width S in the longitudinal direction is preferably from 3 to 100 mm, more preferably from 5 to 80 mm. in addition, the above-mentioned step R2preferably ranges from 2 to 60 mm. the magnitude of the gaps d and e preferably are respectively from 0.1 to 30 mm and from 0.1 to 30 mm.

Since the side parts of each absorbent element 3 in this embodiment, the implementation constitute an inclined plane 3C, the absorbent elements demonstrate good conformability to the body, do not cause any discomfort and is attached to body contours at the point of attachment even in the state in which the absorbent element 3 close to each other. For example, considering the model is a simplified sectional shape, it can be noted that if the deforming force acts on the absorbent body 10, the absorbent elements do not become an obstacle for each other and, thus, does not adversely affect the conformability to the body or the ability to repeat the shape of the body during movement, as the side areas of the two absorbent elements were beveled, even if the absorbent elements are close to each other due to the bending zone of the base sheet between the absorbent element, as shown in Fig.4(a), and in that case, if the absorbent elements 3 are bent and close together, as shown in Fig.4(b).

Fig.5 is a schematic partial plan view which shows the absorbent body 10 according to the modified example of the first embodiment of the present invention, and Fig.6 is an enlarged view in which the absorbent element is raised, and shows the relationship between the dimensions. In this embodiment, the implementation of each absorbent element 3 has a shape with a constriction in the middle on the form in the plan and, in particular, formed in the form of a polygon (inverted hexagonal), in which V-shaped curved portion 3j are arranged on both sides (long sides) of the rectangle. Meanwhile, although in this embodiment, the implementation of set some schemes�political views in plan view, schematic view also covers the forms that are obtained by cutting corners on the schematic image, or rounded shape. In addition, in this embodiment 2 of the implementation of the absorbent elements are arranged in a staggered manner, and the side absorbent elements 3 with narrowing come in contact with each other. In particular, in this embodiment of the absorbent elements are staggered so that the sloping lines that form a V-shaped configuration of absorbent elements with inverted form of the hexagon, parallel and opposite to each other.

Fig.5(a) shows the state of the absorbent body before deformation, and Fig.5(b) shows a state in which the absorbent body is deformed due to application of tensile forces. Appropriate absorbent elements 3 on the base sheet 2 superposed in the longitudinal direction (X direction) and transverse direction (Y direction) on the base sheet 2 and are staggered, wherein the absorbent elements that are next to each other in the transverse direction, are arranged alternately in the transverse direction at intervals in the longitudinal direction, which correspond to steps P2who constitute approximately half of the steps of P1with �which the absorbent elements are arranged in the longitudinal direction. In its natural state (relaxation state) in which the absorbent body 10 has no twisting deformation or the like, as shown in Fig.5(a), between the respective absorbent elements 3 having gaps d and E.

When the absorbent elements 3 are arranged in a similar way, when the application of the tensile force, which acts in the longitudinal direction, the absorbent body 10 in a state while wearing the absorbent product containing absorbent body 10 according to this embodiment 2 of the implementation, and causes a tightening or contraction in the transverse direction (Y direction), and the width And in the transverse direction that is defined in a natural state, becomes the width in the transverse direction that is defined when twisted or tightened condition, the absorbent elements 3, which are adjacent to each other in the transverse direction, approach each other in the area of the inclined planes 3g and 3h on one side of the V-shaped bent parts and are communicated in fluid with each other in plan view. Since in this case the zone of approach or contact of V-shaped inclined planes becomes longer compared with the zone of convergence or contact in the aforementioned embodiment 1 of implementation, and the message on the liquid is carried out in this long�th zone of convergence, can be achieved best transmission fluid or the like. In addition, when placing the absorbent element 3, each of which has a similar form, on the base sheet 2 in a checkerboard pattern as illustrated, the absorbent body 10 is easier to deformation in the longitudinal and transverse directions in a balanced manner, resulting in can be simultaneously ensured conformability to the body and the ability to follow the shape of the body during movement without irregularities, as well as maintaining the ability to absorb fluid or the like.

V-shaped bent portion 3j on each of two opposite side portions of the absorbent element 3 in this embodiment, the implementation has a narrowing angle θ of 90° or more and less than 180°, preferably of 100° to 170°. In addition, in this embodiment of the absorbent element is formed so that L1>L2if the value of the distance between the lower parts of the depressions of the narrowed parts defined as L2and the length of the side that is perpendicular to the longitudinal direction (the X direction in the drawing), is defined as L1. In addition, this polygonal absorbent element 3 having a V-shaped curved portion 3j, fixed on the base sheet 2 only in the area of the locking element 4 in prices�re absorbent element, while the absorbent element just entered into contact with the base sheet 2 on the rear outside surface of the locking element 4 and fixed to the base sheet 2 from the rear outside surface of the locking element 4. In addition, the width L1absorbent element in this embodiment 2 of the implementation in the transverse direction is, for example, preferably from 1 to 50 mm, and the width L2the absorbent element in the transverse direction is preferably from 1 to 50 mm when using the products as sanitary pads. Width W in the longitudinal direction is preferably about 3 to 100 mm.

There is the possibility that in another modified example of the absorbent body according to this embodiment of the absorbent material may be placed in a spatial area between the absorbent element 3 and an absorbent element 3 so that it will have a lower surface density compared to the surface density of the absorbent element 3. In this case, the absorbent material preferably has components that are similar to cellulose fiber, absorbent polymer, and the like, which form the absorbent element 3, but the components are not necessarily limited to the given components.

Mother�l for the formation of the absorbent element 3 is not limited in a particular way, and can be used fibrous materials, porous materials, and combinations thereof and the like. Examples of fibrous material which may be used include: natural fibers, such as fibers of wood pulp, cotton and hemp fiber, single fiber, consisting of synthetic resins, including, for example, a polyolefin resin-based, such as polyethylene and polypropylene, resin-based polyesters such as polyethylene terephthalate, and resins based on polyvinyl alcohol, a two-component fiber comprising two or more kinds of these resins, and semisynthetic fibers such as acetate and hydrocellulose. In cases where fibres are used, consisting of synthetic resin, fiber can be a fiber that can be etched, which are deformed under the action of heat. For example, there is the possibility of using fibers, the fineness of which is increased, but the length of which is reduced under the action of heat, or fibers, the fineness of which is little affected by heat, but the seeming length of which, "occupied" by fiber decreases when the deformation with the formation of serpentine form. Examples of porous materials that may be used include sponges, nonwovens and aggregated masses polymers with high absorbent capacity (i.e., the aggregated mass of polymers with high absorbing ability and fibers) and the like.

As a polymer with high absorbing ability contained in the absorbent element 3, preferably used are the polymers that can absorb and retain a dedicated body fluid medium, having a weight, five times or more greater than the own weight of the polymer, and can form a gel. Form is no specific and may be a spherical shape, form solid, botryoidal form, powder form or in the form of fibers. The polymer preferably has the form of particles having a size, preferably comprising from 1 to 1000 μm, more preferably from 10 to 500 μm. Examples of such polymer with high absorbing ability may include starch, crosslinked carboxymethylcellulose, polymers or copolymers of acrylic acid or alkali metal salts and acrylic acid and the like, polyacrylic acid and its salts and grafted polymers are salts of polyacrylic acid. As a salt of polyacrylic acid can preferably be used the sodium salt. There is also the possibility of a preferred use of copolymers obtained by copolymerization of acrylic acid with a comonomer, such as maleic acid, taconova (metronatural) acid, acrylamide, 2-acrylamide-2-methylpropanesulfonic acid, 2-(meth)acre�lolitashouse acid, 2-hydroxyethyl(meth)acrylate - or styrelseledamot acid, in the range in which the characteristics of the polymer with high absorbing ability does not deteriorate.

In the case where the absorbent elements 3 contain a polymer with high absorbing ability, the proportion of polymer with high absorbing ability in the weight of the absorbent element 3 is preferably from 5 to 95 weight percent. In the case where the absorbent body 10 is used as the absorbent body for sanitary pads or products that are used to absorb fluids emitted in a small amount, for example, with mild incontinence, the proportion of polymer with high absorbing ability in the weight of the absorbent element 3 is preferably from 10 to 30 weight percent. In the case where the absorbent body 10 is used as the absorbent body for products, which are used to absorb fluids emitted in large numbers, for example, for disposable diapers, the proportion of polymer with high absorbing ability in the weight of the absorbent element 3 is preferably from 50 to 80 weight percent.

Regardless of whether the absorbent element 3 polymer ultra-high absorptive capacity or not, Paddys�yosia stretch of the absorbent body 10 preferably has the ability to withhold a 0.9% aqueous solution of sodium chloride in an amount of 0.1 g/g or more, in particular 1 g/g or more, as a stable absorbent characteristics are manifested even when stretching the base sheet 2. To ensure a similar degree of retention, it is preferable to use a combination of fibers having high hydrophilicity and large capillary forces (for example, cellulose, hydrocellulose, and the like), synthetic fibers whose characteristics do not deteriorate under the action of moisture (which is not plastifitsirujushchih or strength which in the wet state is not reduced), and polymer with high absorbing ability as materials for the formation of the absorbent element 3.

As the base sheet 2, on which are fixed the absorbent element 3, the steel sheets having the functions of absorption and distribution of selected liquids. Examples of sheets that has similar functions may include: nonwoven fabrics, films or porous body and the like, which contain fibers having a hydrophilic, or contain fibers that have been processed by the tool on the basis of hydrophilic oil. Data sheets can be single-layer sheets, or may have a multilayer structure comprising a plurality of layers that are connected by a lamination for the formation of a single sheet. From the data sheets the preferred sheet possessing�th ability to stretch and it can be used materials which are not imposed special restrictions. Examples of such sheets may include nonwovens containing fibers containing elastic polymer as the constituent fibers (elastic non-woven materials), films containing elastic polymer (elastic film), an elastic porous body, which consist of elastic polymer, the structure of which had the shape of a three-dimensional mesh using a tool such as foaming or the like. As elastic nonwoven fabrics, elastic tapes and elastic porous bodies can be used the elastic nonwoven fabrics, elastic tapes and elastic porous body, which are known in the art. The base sheet 2 preferably has a surface density of 5 to 50 g/m2in particular from 10 to 30 g/m2.

Preferably, the level of ability to the stretching of the base sheet 2 was 60% or higher and more preferably 80% or higher according to the degree of stretching, which is defined as follows, from the point of view of giving particularly suitable adaptability to the body of the carrier and the ability to change form in accordance with the movement of the carrier. The degree of stretching is determined as follows. The measurement is performed by use�of isawanya device for testing tensile/compression RTC-A (supplied by Orientec Co., Ltd.) in "stretch mode". First get the item for measurement by cutting out the base sheet 2 strips of width 25 mm and length 150 mm. Detail for measurement is placed between the pneumatic cartridges that are installed in the tester tensile/compression during the initial specimen length (distance between chucks) of 100 mm, and detail stretch by lifting the cartridge attached to a torque sensor (with a rated output characteristic of 5 kg) of the device for testing in tension/compression, with a speed of 300 mm/min. When the length of the part for measurement when stretched will be increased by 50% from the initial length of the sample, i.e. 50 mm, the direction of movement of the cartridge is reversed, and the cartridge is lowered at a speed of 300 mm/min and returned to the position corresponding to the original length of the sample. During this activity, the relationship between load, determined by a torque sensor, and extension details for record changes in a graph, and the degree of stretch is obtained from the following equation (1) based on a schedule.

The degree of strain = Elongation at recovery/the Maximum value of elongation (=50 mm)(1)

"Elongation at the restoration of" the Oprah�elaut as distance, on which the cartridge is moved from the place corresponding to the maximum value of elongation (=50 mm), at a time when the load for the first time becomes zero after the start of lowering of the cartridge at the location corresponding to the maximum value of elongation. It should be noted that in cases where the item for measurement cannot be extended to the above-described size, the measurement is carried out according to the method below.

<Detail for measurements>

If we assume that the length of the sheet in the direction from the cartridge until the cartridge is L mm, the length of the plot, which is retained, is S mm, and the width of the sheet is With mm, the sample in the form details for measurements were obtained by cutting the specimen from base of sheet with dimensions (L+2S) mm × mm so that the ratio L:C ratio was 3:5.

<Test>

The sample is placed in the tester tensile/compression when the distance between the cartridges, amounting to L, and the cartridge is raised at a rate of 100×(L/30) mm/min until until the length of the part for measurement, will increase by 50% from the original length of the sample. Then the direction of travel of the cartridge is changed to the opposite, and the cartridge is lowered at a rate of 100×(L/30) mm/min, and return to a position corresponding to the original length of the sample. The calculation is performed in accordance solidous equation (2):

The degree of strain = Elongation at recovery/the Maximum value of elongation (=L/2 mm)(2)

Top sheet preferably consists of permeable for liquids material, which give a soft feel to the skin. For example, there is the possibility of using non-woven materials containing natural fibers, such as cotton, as the material and non-woven materials containing various synthetic fibers, subjected to treatment for imparting hydrophilicity, as a material. Back sheet preferably consists of not permeable to liquid sheet material. Back sheet may consist of permeable material if necessary. To ensure the sufficient water vapor permeability, it is preferable to use a porous film obtained by stretching the film made of synthetic resin, such as polyethylene, in which the powder is obtained consisting of a filler, such as calcium carbonate, was dispersed for the formation of fine pores in it. Examples of the side sheets may include non-woven fabrics, film, sheets, paper and the like. With regard to prevent leaks, it is preferable to form a side sheet of a hydrophobic nonwoven mother�La, having impermeability to liquids or weak permeability, sheet protectors that have the ability to prevent leakage, or the like. The above sheet may be a single sheet or two or more sheets in the form of a combination with a functional sheet, and the like.

As for the compositions and materials for the base sheet and the absorbent element in an absorbent body, it is possible to refer to the patent application of Japan No. 2007-316239 (JP-A-2009-136498) and the patent application of Japan No. 2007-332419.

Although in the above embodiment, the implementation was shown an example of application for sanitary napkin, the absorbent body is not limited to such an absorbent product and can also be applied to disposable diapers, diapers for infants or the elderly and other cowards used in case of incontinence, and the like.

As explained above, the absorbent body according to the first embodiment of the flexibly deformed along the various contours of human bodies and precisely adjacent to the body shape of the carrier, and does not create a feeling of discomfort while wearing. In addition, it provides various effects, which consists in that the absorbent body accurately replicates the deformation of the wearable parts, called movements, does not happen reduction�Oia absorbent characteristics, due to the deformation, and the like.

(The second variant implementation)

Further explained the second embodiment of the present invention, but the explanation of the components that "overlap" components of the above-mentioned first embodiment, is omitted. In addition, the above-mentioned first variant implementation of this second variant of implementation are not independent from each other and mutually exclusive and, for example, the second variant of implementation can be considered as covered by the above-mentioned first variant implementation as a more specific idea. Furthermore, the invention according to the first variant implementation of the invention in accordance with the second variant of implementation of technically interrelated, their relationship is such that it ensures the generation of a single General inventive concept due to the fact that they have the same or corresponding special technical features. As for the symbols in the drawings, identical symbols are used for corresponding elements and the like (however, the size and detail shows the mutual arrangement correspond to the drawing that corresponds to each variant of implementation).

First, a feature that is particularly worthy of note in this� the second variant of implementation, is that the space Q, in each of which the base sheet forming a bottom surface in plan view, is formed between the absorbing elements 3, 3, 3 ..., and the absorbent material 6 is placed in the spaces of Q so that the material has a lower surface density compared to the surface density of the absorbent element 3. Through the creation of a material absorbent element 3 and the absorbent material 6, which are placed in the spaces Q, with a similar ratio of surface densities is provided by the increase in the rate of absorption in the thickness direction, and improves the ability to distribute the liquid, which flows in parts of the space. In addition, also in the case where the absorbent elements 3 are not communicated with each other by the flow of secreted fluid due to the movement or deformation of the absorbent body, the effect of liquid distribution is improved compared with the situation when the absorbent material is absent in these spaces. The absorbent material 6 in this case preferably has components similar to the components constituting the absorbent element 3, such as cellulose fibers and polymer ultra-high absorptive capacity, but the components of absorbent material 6 is not necessarily limited to the above and may be�ü placed absorbent material, having a composition different from the material from which is formed the absorbent element 3. In this variant implementation of the absorbent material 6 is formed from cellulosic fibers 6A and balls 6b polymer ultra-high absorptive capacity. For example, the surface density of the absorbent element 3 is adjusted in the range from 20 to 800 g/cm2more preferably in the range from 100 to 600 g/cm2. In addition, the surface density of the absorbing material 6 on the portions of the spaces between Q absorbent element 3 is preferably adjusted in the range from 2 to 500 g/cm2more preferably adjusted in the range of 5 to 300 g/cm2taking into account the optimization of the above-mentioned properties. In addition, the ratio of the two surface densities (the amount in percentage, obtained by dividing the surface density of the absorbing material 6 in the spaces of Q on the surface density of the absorbent element 3) is preferably adjusted to 80% or less, more preferably adjusted to 50% or less, still more preferably adjusted to 30% or less and particularly preferably adjusted to 10% or less. Despite the fact that the lower limit value of the aforementioned ratio of the surface densities is not limited in a particular way, �data value in practice is 0.1% or more.

Since in this embodiment, implement a small amount of absorbent material 6, such as cellulose and a polymer that is super-absorbent (SAP), located in the spaces Q, as mentioned above, the hydrophilicity of the entire absorbent body increases. Consequently, the rate of liquid absorption from the material surface increases. In addition, when a small amount of absorbent material 6, such as cellulose and a polymer that is super-absorbent (SAP), there is in these spaces that the liquid spreads easily through space. Namely, as the ability of fluids to diffuse/to spread can be achieved to some extent without ensuring the message flow of a liquid, the absorptive capacity of the base is improved. In addition, in the case where spaces are communicated with each other by fluid flow, the diffusion of the liquid is further improved.

The relationship between the absorbent element 3 and the fixing element 4 is the same as the relationship in the above-mentioned first variant implementation. Their dynamic functioning approximately the same, but explained below with respect to this embodiment of the. When attaching the absorbent element 3 on the base sheet 2 only posledstviya elements 4, the gaps d and e between the absorbent element 3 is bent or the like, the base sheet 2 has little effect on the corresponding absorber elements 3 on the base sheet 2 and causes a slight change in shape. On the contrary, deformability is guaranteed, ensuring the bending of the base sheet 2 and the absorbent body, or the like. In particular, for example, when wearing sanitary pad 200 shown in Fig.8, the absorbent elements approach each other due to bending or contraction of the absorbent body, and the intervals d and e, decrease or increase. Thus, the absorbent element 3, 3, 3 ... retain their interaction for the transmission fluid or the like during the deformation of the entire absorbent body 10, with the result that they exhibit good retention of absorbed liquids or the like. In this case, in particular, in this variant implementation of the absorbent material 6 is placed between the absorbing elements 3, 3, 3.... Consequently, the hydrophilicity of the entire absorbent body increases, and the speed of liquid absorption from the surface of the material increases. In addition, due to the presence of absorbent material 6 between the absorbent element 3, the ability of the fluid transfer between the absorbent element�mi 3 is implemented with greater certainty, and thus, the absorbent element 3 is not deformed in the deformation of the entire absorbent body 10, as mentioned above, such as stretching, and perform the function of transmission fluid or the like is also provided when the absorbent elements are separated from each other by intervals c and d (spaces Q). In addition, since the absorbent body 10 according to this embodiment of the formed by the Union of many small independent absorbent elements, it has very good conformability to the body and the ability to follow the shape of the body during movement". This is similar to what was mentioned earlier for the first variant implementation. In addition, the location in a staggered manner, the preferred value of the width T in the transverse direction, the width S in the longitudinal direction, steps R2and the size of the gaps d and e and, in addition, the structures of compounds of the respective elements shown in Fig.10, also similar to the corresponding parameters in the above-mentioned first variant implementation.

Despite the fact that the materials for the formation of the absorbent element 3 is not limited in a particular way, can be used those materials mentioned in the description of the above-mentioned first variant implementation. However, in this embodiment, be implemented thr�tion is preferably applied to the sheet, having the ability to stretch, as the base sheet. The preferred limits of elasticity, the method of measuring the extensibility and the like, associated with the stretchability of the base sheet 2 are similar to corresponding characteristics and method mentioned in the description of the first variant implementation. Top sheet, the composition and materials for absorbent elements, examples of use, advantages associated with their conformability, similar to that which was specified for the above-mentioned first variant implementation.

In accordance with the design of absorbent products, and further modified examples of the above-mentioned respective embodiments, even when they are bent three times or the like in separate packages and the form data are stored for several months for distribution and sale, the fold line being formed by such bending, almost does not remain, and articles quickly recover their original shape, and thus, the above-mentioned good conformability to the body and the ability to follow the shape of the body during movement can be ensured from the beginning of wear. The operation associated with this, explained below.

In the hygienic strip in this embodiment of the a lot of absorbing elements (small absorbent� elements) 3 are arranged at intervals, and between them is formed by the space Q. Therefore, folds almost not formed on the top sheet, even if the strip is folded. In addition, as mentioned below, as part of the upper sheet is placed in the spaces of Q during compression, the applied pressure is removed, and the volume of the upper sheet can be easily and quickly restored when removing the compressive force from the sheet. In addition, since the cutting surface of the absorbing element 3 has the shape of a trapezoid which tapers toward the upper side of the sheet, as in this variant implementation, can be achieved further improved the effect of eliminate crease lines on the top sheet. When considering the model shown in Fig.11(a) as an example of this variant implementation, you can specify that the top sheet 1 in this example consists of hardened parts 1C, half-hardened parts 1b and flexible parts 1A, which are formed by embossing. On the other hand, the cross section of the above space Q is expanded in the direction above the upper sheet in its natural state, and when the absorbent article is packaged individually, the portion above the upper sheet, in particular the flexible portion 1A, are in such condition that they are easily accommodated in the above-mentioned spaces (located in the upper part of the sheet is shown as a hosted parts 1' as the model). As a result, the portion of the upper sheet 1A, deformable in the direction of the spaces Q, creates the possibility of "extinction" compressive force applied in the thickness direction, as a result, eliminates the situation in which the folding lines remain, and also suppressed the decrease in the volume of the upper sheet. In addition, in this embodiment of the absorbent body is also unlikely to be save he has a collapsed condition in comparison with conventional products, and the absorptive capacity, in particular the ability to pass fluid remains good in addition to the above greatly improved the prevention effect of preserving the fold lines on the top sheet, and, thus, extremely stable feeling of dryness. Although it is assumed that the average "columns" in the drawings Fig.11 in the folded state, shown by configurations similar to the configurations in the drawings at the top and bottom "bars", for the purpose of comparison with the drawings.

Fig.11(b) is a top sheet 1B according to another example, and its constituent 1d fibers oriented in the direction from the surface on its upper side to the surface on its back side.

Fig.11(C) is a top sheet according to another example, and the upper sheet has a structure providing improved�tion ability of the fibers themselves to the restoration of the original shape and increasing stiffness in the joints of the fibers by increasing the diameters of the fibers, used for the top surface with the top side, if we consider the top surface side and rear surface side. In particular, when the stiffness in fasten together the parts increases, in combination with an absorbent body is formed of a mesh structure, which provides a partial preservation of the volume of the upper sheet at the expense of the spaces Q, or acceleration of the recovery volume parts, compressed by slightly compressed part (a strong connection that can recover its shape after deformation caused by compression, which produces a greater effect.

On the other hand, Fig.11(d) shows a conventional top sheet 1D and 1g fiber, and many fibers are oriented in the direction of the plane of the sheet. In the conventional structure, containing a combination of such upper sheet and a flat absorbent body 39, with no spaces, top sheet, which was folded and compressed, cannot recover its original thickness.

Despite the fact that the sheet having the well-known materials and composition, can be used for the top sheet 1, preferably it is a non-woven material made of synthetic fibers, in particular of non-woven material obtained by connecting the intersections of the fibers by the method of fusing through the process Probusinessbank or through the process with a steam jet to further enhance the effect of reducing the compression, caused by compressive force, with the aim of restoring the thickness of the space subjected to a compressive force.

In addition, on the basis of Fig.11 explained in the example of the upper sheet and the effect of recovery of its thickness.

(1) Convex-concave structure, which permits the formation of convex sections, in particular independent of the convex sections (Fig.11(a))

(2) Components of a fiber having a strong orientation through the thickness (the orientation of the surface with the top side to the bottom side) (Fig.11(b))

(3) the Average distance between the fibers with more upper side than the posterior side (Fig.11(C))

When the upper sheet 1A according to (1) shown in Fig.11(a), the flexible portion 1A, which form the convex portions are located on sites that contain absorbent material 6 low density data part 1A is unlikely to be in spaces of Q during use, and easy to maintain the thickness of the upper sheetin General. In addition, not only in the case when the nonwoven fabric is used, in which the point of intersection of the fibers were bonded by the connection method of thermoplasty, the effect consists in the fact that the thickness of the compressed parts (half-cured parts 1b and hardened parts 1C) is easily reduced by the thickness of the flexible parts 1A,which form the convex portions. If the element with the structure with ridges and grooves, in which the convex portions continuously extend in one direction, restoring the thickness of the "weakened" due to the impact of compressed convex sections due to the continuity of the comb-like sections (convex areas), more preferable to use an element with the structure with ridges and grooves, having the form of a separate and independent convex sections. In addition, in the case where the concave portions are made such that they had a higher density compared to the density of the convex sections, by stamping or the like, the preferred option of independent convex portions, since the half-solidified parts 1b and solidified portion 1C in the area have a concave structure, which almost will not be squeezed, when compared with the convex portions, and can be arranged so that the concave portions will have parts that overlap with the absorbent element, whereby the height of the absorbent elements in places of overlap becomes smaller than the height of the surrounding absorbent elements, and easily gaps that hinder the compression of the top sheet.

Despite the fact that in the upper sheet 1B according to (2) shown in Fig.11(b), the inclined part of the convex sections, the convex�about-concave structure may also have similar structures, convex portions preferably have shapes which provide them with a protrusion in the form of parallel lines from the embossed concave, described in the patent application of Japan No. 2008-331374, and non-woven fabric in which the fibers were oriented in the longitudinal direction through the injection flow of gas in the process of passing air through or by processing a stream of steam, is preferred.

In the upper sheet 1C according to (3) shown in Fig.11(C), the average distance (Ie) between the fibers in the layer 1E of the groups of fibers running parallel, is set such that it was bigger than the average distance (If) between the fibers in the layer of groups of intersecting fibers (Ie>If). As a way to provide different average distances between the fibers from the upper side and the back side is preferably selected method of thickening fibers to be used, the method of selecting the polymeric material of the fibers or the like, with the effect provided strong ability to restore the original form of the squeezed state through a mesh structure, which is achieved by increasing the stiffness of the United sections of the fibers; however, from the viewpoint of the texture of non-woven material, more preferred is a method of increasing �volume of polymer fusion-bonded parts in the fibers, and fiber, which provide the increase of the zones of connection by alloying of the United parts, since the distance between the fibers of the upper side is increased by the presence of parallel connecting parts of the upper side, and the structure of the nonwoven fabric becomes a constructive element to be formed so that it will be easy to restore the original form of the squeezed state.

Due to the presence of one or more of the above structures (1) to(3) top sheet can be obtained an absorbent product, which has better absorptive capacity, particularly the capacity for transmission of fluids, even after removal from the packaging the products are Packed separately. In addition, as a means of improving the ability of the upper sheet to pass the liquid to give an example of how education upper sheet, which is hydrophilic in General, but in his view the plan identifies the hydrophobic part and hydrophilic part, which is preferred because of the feeling of dryness created by a top plate, can be strengthened. Furthermore, it is preferable to place the convex parts convexo-concave structures with a hydrophobic side and the concave portions with a hydrophilic side, because the movement of fluid in the upper sheet can b�th further improved, and the feeling of dryness can be enhanced further.

In this embodiment, the implementation of density (D1) of the upper sheet 1 is set lower than the density (D3) absorbent element 3. Thus, due to the large capillary forces arising from the high density (D3) absorbent element 3 (D3>D1), can be improved the ability of the top sheet 1 to pass the liquid, and the remaining amount of liquid can also be reduced. In addition, since in this embodiment, the implementation part, which is the absorbent material 6, which is formed from materials similar to the materials of the absorbent element 3, and has a low density, are more hydrophilic surfaces compared to hydrophilic fiber material in the top sheet 1, they can provide the suction of the liquid from the contact surface of the fiber. As a result the entire surface of the absorbent body provides easy retraction of fluid from the top sheet, whereby the amount of liquid remaining on the top sheet can be reduced, and a feeling of dryness can be enhanced further. In addition, the case in which the density of the upper sheet 1 is higher than the density of the absorbent material 6 (the portion with a low density (D3>D1 >D6), is more preferable because in this case the compression of the upper sheet is difficult.

Unless otherwise noted, average values of density measured as follows.

(1) the density of the absorbent element (D3)

Since the density is the quotient of the mass (g) volume (cm3), provide measurements of mass and volume of the absorbing element. The mass was measured after cutting out the pieces with dimensions of 5 cm × 5 cm (the Value obtained as the arithmetic mean of the values obtained for three parts or three absorbent products, defined as the mass of the sample). To measure the volume use the sample weight was determined, and the system KS-1100 (trade name) for shape measurement with high accuracy and KS-Analyzer (trade name) manufactured by Keyence Corporation. Settings system KS-1100 during the measurements were as follows: initial position measurements (X=0, Y=0), measuring range (X=40000 μm, Y=40000 μm), the measurement step (X=20 ám, Y=20 µm) and speed: 7500 microns. The device KS-Analyzer is used after correcting the measured values via the menu "adjustments". Setting adjustments were made to size 3×3, the number of passes equal to 1, and the level equal to 100. Then perform a measurement on the entire menu area "dimensions" (still� way the measurement range is 4 cm × 4 cm), and the density is obtained from the mass and volume through the use of the average value for three specimens which were cut in the form of volume elements. In the case where the shape of the surface section such as the shape of a trapezoid and a semicircle, which can be captured by the upper surface of the table, which must be placed the sample, defined as the baseline (zero value), while in the case where the cross section cannot be measured by only the upper surface, as in the case of the hexagon (Fig.12(C)), the corresponding volume is obtained by means of the corresponding position of the baseline when measuring from the top and bottom surfaces or through the use of full size obtained by measuring the individual absorbent elements.

In addition, the outer parts of the absorbent element sometimes partially separated at the time of manufacture, and in such a case, the parts are somewhat vagueforms or separation from the absorbent material becomes uncertain. In such a case, the measurement is carried out using the processing described in the following section (3) on the definition of density (D6) fibers of absorbent material.

(2) �the multiplied volume (D 1) fibers of the top sheet

In the case of a flat top sheet density can be determined from mass and volume, through the use of mass, measured size and T0obtained through measurements using a KES-G5 Handy Compression Tester, while in the case where the top plate has a convex-concave structure, the density (D1top sheet is calculated by measuring the mass and volume in a manner similar to the above-mentioned approach (1).

In addition, in the case when between the top sheet and the absorbent element, there is an intermediate element, such as an intermediate sheet, the average density of the elements of the upper sheet, including an intermediate element, defined as above the density (D1).

(3) the Density (D6) absorbent material

The density (D6absorbent material is calculated before the measurement of the above-mentioned absorbent element. Cut out a sample with dimensions of 5 cm × 5 cm, and measure its mass, and measure its volume through the system KS-1100 for shape measurement with high accuracy and KS-Analyzer manufactured by Keyence Corporation; then measure the mass and volume of the specimen from which the above-mentioned absorbent material located between the absorbent elements�Tami, was removed, and the mass and volume of absorbent elements is subtracted from the initial mass and volume, whereby can be obtained the mass and volume of absorbent material and can be calculated from the density (D6. Absorbent material located between the absorbent element, is preferably removed by using tweezers/forceps or the like. This is necessary in order to prevent damage to the surface of the absorbent element, which leads to the impossibility of differentiating between the absorbent element and the absorbent material and is caused by an external force, such as wind power, and because of the fiber, and the like are carried by the air are separated and fall to the absorbent elements, as a rule, may not occur "exfoliation" of the surfaces of the absorber elements caused by removal using tweezers/tongs.

The outer parts of the absorbent element sometimes partially separated at the time of manufacture, and in such case the pieces have a somewhat vague form, or separation from the absorbent material becomes uncertain. In this case, attempt removal with the help of tweezers/forceps after measurements of mass and volume, and in the case where only weakly connected parts can be removed, they operate as abso�berousek material and the mass and volume of absorbent elements are measured again.

If either of the two above-mentioned calculation of the density of the elements of the part in which the component material is missing, such as open pores, do not take into account the measurements, while the pre-determined zone containing a relatively small part of the structure within convex areas and concave areas, delineate and include in calculations, and density was calculated as the density of each part of the structure averaged convex sections and concave sections and obtaining the average density.

Because according to this variant implementation of the density gradient between the top sheet and the absorbent element is set as described above, in the case where the amount of liquid which has passed through the top sheet, small, individual absorbent elements absorb the liquid quickly. On the other hand, in the case where the amount of liquid which has passed through the top sheet, large, due to the fact that the space Q or absorbent material 6 placed therein are in areas where the individual absorbent elements are separated from each other, the liquid may temporarily accumulate in these areas. Consequently, almost no liquid will spread on the upper sheet even in the case where the volume of the evolved menstrual blood, and Reza�the adds this can be achieved the feeling of greater dryness of the upper sheet.

As mentioned above, usually in the presence of each individual package, in which the absorbent article is folded such option or package in which the individual absorbent articles are superposed on one another, a condition in which pressure is applied in the thickness direction, the absorbent product is maintained. Consequently, the top sheet and the absorbent body is compressed in the thickness direction, and the space in which the fluid passes easily, "squeezed" due to a certain reduction of volume of the upper sheet. Thus, the resistance to the passage of the fluid increases, and the amount of liquid remaining on the top sheet, is significantly increased. On the other hand, when using this embodiment, even in the case of packing individually or in packages of multiple products, the application of pressure to the upper sheet will be difficult, since the absorbent body is formed space, which can accommodate a portion of the upper sheet, the result of which can be provided with stable characteristics when wearing due to the fact that is unlikely to be reduced ability to pass the liquid.

Fig.12 is an enlarged cross-section which schematically shows the state of the absorbent element and the absorbent material in accordance with sootvetstvuyushiye the implementation of the absorbent product of the present invention. Can be used absorbent body having a different shape, similar to that shown in the figure. In an embodiment, (a) the implementation of absorbent elements 3, each of which has a trapezoidal cross section, as in the above-mentioned first variant implementation, fossa, which correspond to the individual absorbent elements 3 formed on the drum for laying fibers during manufacture. When moving absorbent elements on a back sheet, it is preferable to provide for displacement of air from the absorbent element, since the absorbent element 3 can be formed accurately in respect of the above spaces of Q. moreover, by "squeezing" air to the peripheral portion of the absorbent element 3 are loosened, and the result is a trapezoidal portion having a high density that remain, and parts on which is placed an absorbent material 6 having a low density. Since the absorbent material 6 is often omitted toward the rear side of the sheet and has a fossa, in the case where the amount of air that is squeezed out is small, it is preferable to increase the amount of squeezing of the air in order to make all the absorbent body is approximately flat. Alternatively, for a more reliable molding premise�plant to carry out the injection of the air flow from the top sheet or the back sheet on the operations which is different from the operations performed on the drum for laying fibers. In this case, it is preferably carried out after the transfer of absorbent elements on the base sheet 2 and fixing them to the base sheet 2 in order to exclude a situation in which violated a specific arrangement of the absorbent element 3, and to improve the passage of air.

Fig.12(b) and (C) show the surface shape of the cross sections of the absorbing elements 3, which may be formed in a similar way. Because in a variant implementation, shown in Fig.12(b), the absorbent elements are semicircular surfaces of the sections, they are in a state of small contact with the top sheet, resulting in compression of the top sheet caused by compression, can be relatively reduced in comparison with the trapezoids. In a variant implementation, shown in Fig.12(C), the gaps or parts with low density, intended for distribution of fluid, are also located at the back of the sheet, whereby can be obtained a structure which is almost not influenced by the state of wear (mainly pressure when wearing).

Fig.13 is an enlarged perspective view that schematically shows the positioning of the absorber elements according to the respective embodiments imple�of estline absorbent products of the present invention. In images (a)-(C) in the figure the location of the absorbent element, the absorbent bodies are shown as States in which the absorbent material 6 is missing. In those embodiments in which space Q have no absorbent material 6, as just described, the aforementioned displacement of the airflow is reduced to a greater extent during manufacture to reduce the "loosening" of the surfaces of the absorber elements 3, and the adhesion with the transfer is carried out by means of glue, which was applied to the back sheet 7, and thus, the distribution of fluid through the gaps in the absorbent body becomes more predominant. This leads to improved dryness of the upper absorbent sheet products, and the remaining amount of liquid is also reduced because the top sheet 1 "repeats" separate forms of absorbent elements 3 from the top of the sheet.

Fig.14 is a cross-section that schematically shows a sanitary pad in accordance with another variant implementation of the absorbent product of the present invention. The figure shows as a fourth embodiment of a cross-section of a sanitary napkin 300 containing the top sheet and the absorbent body, and the intermediate sheet 9 located between them. This gig�ediceskaja strip 300 has the structure a similar structure of the sanitary pad 200 according to the second variant of implementation except that the placement of an intermediate layer, and below explains the differing part.

As an intermediate sheet 9 can be used non-woven material obtained through the process of passing air through or process steam jet, as in the case of the upper sheet and the sheet on which were formed open pores (cracks) and the like. To ensure transmission fluid (reducing the amount of remaining liquid) intermediate sheet preferably has no convexities and concavities, and the density (D9its fibers is preferably higher than the density (D1) fibers of the top sheet, and preferably lower than the density (D3) fibers of absorbent elements 3 (D3>D9>D1). In addition, the density of the fibers of the intermediate sheet may be determined in a manner similar to the method of determining the density of the aforementioned fibers of the top sheet.

Since the intermediate sheet 9 is placed, the absorbent product provides improved feeling of dryness and a good sense of springback, and the absorbent body acquires properties that provide stable transportation (moving) at the time of manufacture. In addition, absorber�their product more difficult to compression and retention in by a strangled state, caused by compression. In the case where the layer of the BATT, which was not converted into a nonwoven fabric by, for example, compounds of fibers by fusing or the like, or a sheet having raised Spasenie fiber, is used on one side of the intermediate layer instead of a flat sheet material, shown in the drawing, the ability of the intermediate sheet to contact with the absorbent element 3 is improved even in the case where between the absorbent element 3 is missing absorbent material 6, or a structure is used that has not been smoothed by means of absorbent material 6, whereby easily ensured by reducing the number of remaining fluid.

The present invention should not be construed as limited to the aforementioned respective embodiments of the implementation, and, for example, the set of absorbent elements 3 may have a different thickness is the same thickness. In addition, the structure in which the side pieces of absorbent elements have a smaller height as compared with the center, can be selected in order to improve wearing comfort, and structure, which uses a combination or mixture of two or three types of absorbent elements having different heights can be selected in order to reduce the compression top l�hundred, caused by compression.

Examples

Further, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these.

(Example and Comparative example, corresponding to the first variant implementation)

Prepared test sample absorbent body having the shape shown in Fig.7(a) (however, the sizes of the respective elements described on the basis of the symbols shown in Fig.3). Element based on a mixture of cellulose and polymer ultra-high absorptive capacity (200/50 g/m2) was used as absorbent elements, and non-woven material based on block-copolymer of styrene and ethylene propylene with alternating blocks (SEPS, 13 g/m2) was used as the base sheet. Each absorbent element had a width of T=6.0 mm in the transverse direction and the width S=13.5 mm in the longitudinal direction, and the absorbent elements were arranged in steps R2=7.5 mm and a gap of d=1.5 mm and e=1.0 mm. Absorbent elements were fixed to the base sheet through the use of ultrasonic embossing (radius: 1.0 mm).

Fig.7(b) is a plan view of a state in which the above-mentioned test sample absorbent body is stretched by 30% in the length direction. To the state of the natural�th length, rectangular absorbent elements 3 were placed in a checkerboard pattern on the base sheet 2, while maintaining approximately the same clearances in the longitudinal direction and the transverse direction. When all the absorbent body 10 has been stretched in the longitudinal direction (X direction) of the absorbent body from a given state, the absorbent body 10 is subjected to contraction in the transverse direction (Y direction). In this example for testing the degree of stretching in the longitudinal direction was 30%, while the degree of contraction in the transverse direction of the width was 14%.

It should be understood that, since each of the absorbent element 3 is fixed to the base sheet 2 only through the Central fixing element 4 (Fig.2) even in such a stretched state is no impact on the form of a separate absorbent element, and only stretched base sheet 2, and increasing gaps between the absorbent element 3 in the longitudinal direction. It was confirmed that in this case, the liquid is effectively moved between the adjacent absorbent element 3 in the longitudinal and transverse directions, the absorbent elements, as shown by the arrows f and h, in a stretched state (Fig.7(b)).

Then, on the stretchable base sheet having such �larger the surface area, that the above test body had the shape and surface area of similar shape and surface area of the absorbent body manufactured in industrial usual hygienic seal, there was prepared a test piece of the absorbent body, in which the number of absorbent elements was increased and absorbent elements are arranged in a checkerboard pattern without changing the size of the individual absorbent elements and gaps between them. The test sample 101 (Example) sanitary napkin was prepared by incorporating the test sample absorbent body prepared, as mentioned above, with a top sheet, a back sheet, a side sheet and the like are similar to corresponding elements of the above-mentioned industrial manufactured sanitary pads. For comparison as the above-mentioned industrial manufactured sanitary pads continuous element (with dimensions of 75 mm × 200 mm) conventional product (test sample C11) (cellulose/polymer ultra-high absorptive capacity (SAP)) (200/50 g/m2) was used as the absorbent body (Comparative example). In addition, there was prepared a piece of regular fabric for underwear (cotton 45%, rayon 45%, polyurethane 10%) that has been cut with a form similar to the form of the above�Uta industrial manufactured sanitary pads (test sample s11) (reference example). Through the use of these test specimens of Example, Comparative example and reference example bending moments and shear stress were measured in accordance with the following methods, and the measurement results are shown in table 1.

(Method of measuring bending moment)

The unit KES-FBS-L (trade name) manufactured by Kato Tech Co., Ltd., was used as a measuring device. The measurement was performed at the maximum curvature ±0.5 cm-1and the rate of change of curvature during deformation, component 0,5 cm-1/s (constant), and clip width was 40 mm, and the width of the specimen was 25 mm. the Measurement was performed under the following conditions: the temperature was 20°C and the humidity was 65%.

(Method of measuring shear forces)

The unit KES-FB1-AUTO-A (trade name) manufactured by Kato Tech Co., Ltd., was used as a measuring device. The measurement was performed with a maximum shift value of ±tan 8°, and the shear rate, component 0,5°/s, and clip width was 5 mm, and the width of the sample was 20 mm. the Measurement was performed under the following conditions: the temperature was 20°C and the humidity was 65%.

It should be understood that the product, which uses an absorbent body according to the present invention (Example), shows the magnitude of the bending moment, which is close to the magnitude of the bending moment to the subject of underwear when compared with the conventional product (Comparative example), and is flexibly attached to the various forms of the human body to provide an extremely good prelevement to the human body. In addition, in the product, which uses an absorbent body according to the present invention (Example), was created only the shear stress, which was near�about the voltage when the shift in the subject of underwear, when compared with the conventional product (Comparative example). Thus, it should be understood that the absorbent body of the present invention follows the shape of the human body in motion and accurately deformed in accordance with movement of the human body, has an extremely high ability to repeat the form and creates a feeling of discomfort, even in cases when you perform various movements.

(The example and the Comparative example corresponding to the second variant implementation)

There was prepared a test piece of the absorbent body shown in Fig.10(a) (absorbent material 6 is excluded in Fig.3). The mixture of cellulose and polymer ultra-high absorptive capacity, molded in the form of a truncated pyramid (200/50 g/m2), similar illustrated, was used as absorbent elements, and non-woven material having a width in the transverse direction equal to 200 mm, and a width in the longitudinal direction, a dimension of 100 mm, was used as the base sheet. The dimensions of each absorbent element were as follows: the width in the transverse direction T=6.5 mm, and the width in the longitudinal direction S=13 mm, and the absorbent elements were placed with P2=7.5 mm and with a distance d=1.5 mm and e=1.0 mm (see Fig.8 and Fig.10, which shows the symbols that represent resp�relevant dimensions). Absorbent elements were fixed to the base sheet through the use of ultrasonic embossing (radius: 1.0 mm). The absorbent material consisting of a material similar to the material of the absorbent element, which has not been subjected to forming, was replaced by an air space extending between the absorbent element, and put between the absorbing elements. The ratio of the surface density of the absorber elements and the surface density of the absorbing material (the ratio of the surface densities) can be obtained by the following methods.

1. Determine the surface density of the entire absorbent body (absorbent material in the absorbent elements (truncated pyramids) + nonwoven + absorbent material in the spaces between the absorbent elements).

2. Ten of absorbent elements, each of which has the shape of a truncated pyramid, arbitrarily cut out in the state in which they include a nonwoven material, and determine their surface density, and get the average value. Then by subtraction of the surface density of the nonwoven material, which was determined in advance, from this mean value receive the surface density of the absorbent element.

<> 3. The surface density of absorbing material in the spaces between the absorbent element is calculated as follows: the surface density of absorbing material in the spaces between the absorbent element = total surface density surface density of the nonwoven material is the surface density of the absorbing elements.

4. The ratio of the surface density of absorbent elements to the surface density of the absorbing material (the ratio of the surface densities) is calculated as follows:

{(the surface density of absorbing material in the spaces between the absorbent elements)/(the surface density of the absorbent element)}×100 (%).

As the above-mentioned test samples of absorbent bodies were respectively prepared test sample, in which as the material for formation of a base sheet used non-woven material with the structure of SMS (non-woven spunbond material mode of production (S) - non-woven material obtained aerodynamic method from the melt (M) is a non-woven spunbond material mode of production (S)) (manufactured by company Unitika Ltd., trade name: Eleves) (test sample 201: Example), and the test sample, which used susceptible races�aguilaniu nonwoven fabric MV (polymer manufactured by Kuraray company Corporation, trade name: Septon obtained by converting Septon material in non-woven fabric by using a device company intended to implement aerodynamic method of producing a nonwoven fabric from melt) (test sample 202: Example). For comparison with the above test samples were prepared absorbent body used in industrial manufactured sanitary napkins, which was cut with a form similar to the form of the above-mentioned test specimens (Comparative example: test sample C21). Through the use of these test samples according to Examples and Comparative example bending stiffness was measured in accordance with the following methods, and the results were shown in table 2.

(Method of measuring bending stiffness)

In the case of the test sample� C21 absorbent body (Comparative example) in the normal product high bending stiffness was shown both in the MD direction (the direction of movement of the material in the car), and in the direction CD (cross direction). On the other hand, in the absorbent elements according to the present invention (test samples 201 and 202, Examples) bending stiffness was significantly reduced in the MD direction and in the direction CD. Thus, it should be understood that when using the absorbent body of the present invention the absorbent body exactly follows the shape of the human body during the movement of the human body and is deformed in accordance with movement of the human body, has an extremely high ability to follow the shape of the body and creates a feeling of inconvenience in case when you perform various movements.

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to purulent surgery, and can be used to treat acute and chronic septic wounds. That is ensured by pre-measuring patient's capillary wall resistance on the involved body area, which is covered with a vacuum dressing, underneath which a low pressure within the range of 50-200 torr is generated for a period of time being no more than 20 times greater than the resistance time. Once this period of time expires, the wound is drained and bathed at the above low pressure by administering an antiseptic, which is presented by an anolyte with hydrogen concentration pHan falling within the range of 2≤(pH)an≤4, and the oxidation-reduction potential (Eh)an ranging from [1,000≤(Eh)an≤1,200] mV. The drainage and bathing procedures last for 5-10 minutes. That is followed by 3-5-minute pressure reset, and the anolyte supply is shut off; the anolyte with the wound discharge is evacuated until the pressure underneath the vacuum dressing re-drops to 50-200 torr. Thereafter, the anolyte is re-supplied to the wound through a drain tube. The cycles are alternated for 5-8 times. The vacuum dressing is removed from the septic wound, and the necrotic tissue areas are covered with pepsin powder and dressed or drained through anolyte gauze drain sponges. A 4-6-hour break is followed by replacing the anolyte dressing with pepsin by the vacuum dressing, and the similar alternating process mentioned above is repeated. The procedure is performed 2 or 3 times a day for 3 or 5 days within the therapeutic course. As the wound heals, and the local oedema and bacterial content decrease, the above therapeutic cycle is to be repeated. The flushing drainage and bathing therapy involves replacing the anolyte by catholyte, the hydrogen concentration pH of which lies in the range of 8≤(pH)an≤13, whereas the oxidation-reduction potential (Eh)cat varies within [-820≤(Eh)cat≤-300] mV. As the catholyte flows to the wound, infrasonic vibrations of the power of 10-2 to 1 W/cm2 continuously and periodically varying within the range of 10 to 30 Hz and back are excited. The drainage and bathing procedure with the periodic ultrasound in the above frequency range lasts for 15-20 minutes. The ultrasound is switched off, the catholyte supply is shut off from the wound until the pressure underneath the vacuum dressing re-drops to 50-200 torr. The catholyte flows to the wound again, and infrasonic vibrations of the power of 10-2 to 1 W/cm2 continuously and periodically varying within the range of 10 to 30 Hz and back are excited. The cycles are alternated for 5-8 times. Once the catholyte evacuation from the wound is terminated, the last cycle of the alternating process involves removing the dressing from the healing wound, however tissues impregnated with the catholyte are left in the wound. The above procedure is performed 4-6 hours later, up to 2 or 3 times a day until the therapy is completed.

EFFECT: method provides the effective treatment of the septic wounds at the various stages by pathogenetically substantiated target in the polymicrobial wound contamination.
