The technical field to which the invention relates.

The invention relates to an absorbent product such as a sanitary pad, strip panties or pad used in case of incontinence, having a longitudinal direction and a transverse direction, two side edges, taking place essentially in the longitudinal direction, the front part, rear part, the first surface and the second surface, and an absorbent element positioned between the first surface and the second surface. The invention also includes a method of manufacturing such a product.

Prior art

Absorbent articles mentioned in the introduction, in most cases supplied is not permeable to liquid back layer, typically not permeable to the liquid layer of plastic film. However, they are the problem, namely, that the product felt how wet and uncomfortable when worn. Humidity can also cause discomfort in the form of unpleasant odor and skin irritation. Thus, more practice became a supply of absorbent breathable products is not permeable to liquid layers, for example microporous plastic films or impermeable non-woven materials. Examples of breathable materials are given in the documents EP 813848, EP 813849, EP 71047, EP 25315 and US 4713069. Such breathable barrier layers, however, do not create an adequate effect is impermeable to liquids and, thus, in practice generally only used as pads in panties, when the number of absorbed liquid is very small. Sanitary napkins and pads used in case of incontinence, which should absorb much larger quantities of liquid, therefore, continue to provide fully permeable fluid barrier layers. Therefore, there is a need to improve the air permeability of the absorbent products such as sanitary napkins, pads in panties and pads used in case of incontinence.

Absorbent products such as sanitary napkins, pads in panties and pads used in case of incontinence, designed to be worn in close contact with user's body. In this regard, such an absorbent article is usually placed under short cowards user, and it is held in contact with the body of the pressure exerted on short shorts. Recently, however, women are more so-called underpants "string", i.e. briefs, in which the rear of the perineal part is very narrow. In this regard, sanitary napkins, pads, pants and pads are used is when incontinence, intended for use in normal short shorts, as detected, it is virtually impossible to consolidate in a narrow shorts so that a sanitary pad or gasket under tights correctly installed on the user's body and held in place during the entire period of use. In addition, narrow briefs are often aesthetic purposes, because they are virtually invisible even under tight-fitting clothing and do not cause the formation of unsightly lines on the edge of the pants or folds on the clothes. Using conventional absorbent articles, which stands for the edge of the narrow pants, a large part of the desired aesthetic effect of wearing narrow pants of course lost. Thus, were proposed to absorbent articles which are adapted to form narrow pants. Such absorbent articles are described in documents SE 9803981-1, WO 97/39713 and SE 9901758-4. However, the special, essentially triangular shape with a very narrow rear part, which is necessary for conformity narrow cowards, means that the surface area available for absorption is relatively small. In this case, the risk of leakage if the product cannot capture and absorb all the liquid, secreted by the body.

One object of the invention, therefore, is to obtain breathable absor youseo products with an enhanced ability to absorb moisture. Another objective of the invention to provide a breathable absorbent articles with a high degree of protection against leaks. Another objective of the invention to provide a breathable absorbent articles, which are suitable for use with narrow cowards.

Description of the invention

Thanks to the present invention obtained absorbent product of the type specified in the introduction, which essentially eliminates the above difficulties. The product corresponding to the invention, differs mainly in that the absorbent element has a region of accumulation of fluid and the area of the secondary absorption, and the area of the secondary absorption contains parts that completely surround the area of accumulation of fluid in the plane of the product, the area of the accumulation of fluid has at least 75% of the total absorptive capacity of the product, and the layer is not permeable to the liquid material is located on the second surface and substantially within the region of accumulation of fluid.

Thanks to the concentration of absorptive capacity in the core area of the absorption liquid, where the liquid can be absorbed and accumulate, you can restrict and control the distribution of fluid in the absorbent product. In the result, you can also limit the length is not permeable to liquid the spine of the barrier layer of the product in this area, because other parts of the product, expected to absorb only very small quantities of liquid.

Preferably, if the accumulation of liquid essentially consists of more onkocupressora and/or more hydrophilic material than the area of the secondary absorption, or if the accumulation of liquid contains overabsorbed, because it means that the fluid will move in the direction of the field of secondary absorption in the region of the accumulation of fluid, but not in the opposite direction. In the edge region of liquid accumulation also function as barriers to liquid so that the liquid will not pass from the field of liquid accumulation in the more fuzzy and/or less hydrophilic region of the secondary absorption, while the area of the accumulation of liquid is not saturated with liquid.

It was found that absorbent articles worn with narrow shorts, stays in place surprisingly well and, thus, to a large extent you can predict where it will happen hydration and absorption. The present invention uses this fact to perform the Central region of the absorption liquid with greater absorptive capacity and a high degree of resistance to leakage relative to the rest of the product.

According to one variant of osushestvlyaetsya, the absorbent product is in terms of essentially triangular configuration with the back shorter than the front part. This configuration makes the product especially suitable for use with narrow cowards.

The absorbent article can also be supplied permeable to the liquid layer on the back side, which is located on the second surface, i.e. the surface that faces the undergarment of the user when using the device. In this regard, the layer is impermeable to the liquid material is located between the area of the accumulation of liquid absorbent products and permeable to the liquid layer on the back side. Such permeable to the liquid layer on the back side contains a nonwoven layer that attaches to the outside of the product, the properties of textiles. Textile back side of the product provides a number of benefits, such as comfort, good friction and, thus, better retention in lingerie and attractive appearance.

According to one variant of the invention, the layer is not permeable to the liquid material is connected with accumulation of fluid absorbent element on the surface area of liquid accumulation, which under use of the product should be facing away from the user side. This option is implemented the program of the invention enables manipulation of the combination of the material for the accumulation of fluid and the barrier layer as a single component in the production process.

The area of the accumulation of liquid must have a high absorptive capacity and good ability distribution and accumulation of fluid. In this regard, the advantage is that if the accumulation of liquid contains a layer of cellulose fibers with a density of at least 150 g/m3and, preferably, a layer of cellulose fibers, formed by a dry process, with a density of at least 250 g/m3.

The material, which was considered suitable for the area of the secondary absorption, contains a layer of associated material based on cellulose fibers with a density of at most 125 g/m3, which is located on the first surface and passes over the region of accumulation of liquid and the edge region of the accumulation of fluid around the periphery of the field of accumulation of fluid. In an alternative embodiment, the material of the secondary intake is only around the periphery of the field of accumulation of fluid. In this context, the associated material means material that is processed binder to stabilize the fibrous structure ply. Accordingly, the material can be associated with the use of latex and/or binder fibers.

According to one variant of the invention, the material of the back side consists of a breathable material with high resistance to pron is knowing liquid.

According to another variant embodiment of the invention, the scope of the accumulation of liquid has absorptive capacity, reaching at least 85% of the total absorptive capacity of the product.

The product may also have an adhesive fastening means, which is located on the material of the back side and allows the passage of gas and water vapor in the area of the secondary absorption.

The invention also provides a method of obtaining an absorbent product according to claim 1 of the claims. The method includes the imposition of a continuous web of absorbent material first surface on which the layer is not permeable to liquid material, after which the area for the accumulation of liquid cut down or cut out from the obtained laminated material consisting of absorbent material and is not permeable to the liquid material, and a continuous webs of material secondary absorption connected with a second surface of the cut out areas of the accumulation of liquid so that they were completely surrounded by the material of the secondary absorption in the plane of the leaf material, then from the completed laminate is cut down or cut out absorbent products.

According to one variant of the invention, before the absorbent product will be cut from the finished laminate, at least one of the surfaces of the layered material, consisting of a material of the secondary absorption and accumulation of fluid, attach the coating is permeable to the liquid material.

Brief description of drawings

The invention is described in more detail below with reference to typical variations in its implementation, shown in the accompanying drawings, in which:

figure 1 depicts a sanitary pad that corresponds to the first variant of the invention,

figure 2 depicts a cross-section along the line II-II, made in hygienic pad shown in figure 1,

figure 3 depicts a sanitary pad corresponding to the second variant of the invention, and

figure 4 depicts a cross-section on the line IV-IV, made in hygienic pad shown in figure 3.

The method of carrying out the invention

Sanitary pad 101, shown in figures 1 and 2, contains permeable to the liquid surface layer 102 located on the side of the sanitary pads that must be addressed to the user, permeable to fluid layer 103 a rear side located on the side of the sanitary pads that should be facing away from the user side, and an absorbent element 105 that is enclosed between the two surface layers 102, 103. Between absorbent ele is entom and the back layer 103 is also not permeable to fluid layer 104.

Permeable to the liquid surface layer 102 has the same configuration and size as the absorbent element 105. Layer 103 back side is also configured as an absorbent element. The surface layers 102, 103 are connected with absorbent element 105, for example by gluing, flash or welding with heat or ultrasound.

Permeable to the liquid surface layer 102 is a layer of conventional type and may, therefore, be made of any permeable to fluid material suitable for this purpose. Examples of such material are different types of thin non-woven material, perforated plastic film, net material, permeable to liquid foam material or the like. Permeable to the liquid surface layer 102 may consist of two or more different materials to provide different functions of the surface layer. For example, is the usual location of the transmitting liquid layer inside the host liquid layer. Also know the location of different types of material in different parts of the surface of the sanitary pads that face the user. Thus, a material with good receiving ability may predominantly be located in the part of the sanitary pads, which as expected is I, will get damp in the first place the main part of the liquid from the body, while the part of the surface layer, which first and foremost should be the contact surface with the user's body, provided with a material which optimally soft and gentle for the skin. According to the invention is also not necessary that is permeable to the liquid surface layer 102 comprised of a separate layer of material, the surface layer 102 may be a surface of the absorbent element 105 sanitary pads 101.

Permeable to fluid layer 103 of the back side may also be composed of any suitable permeable to the liquid material. Especially preferred materials are soft non-woven materials, which provide soft, gentle to skin textile surface. The use of textile surface material provides a number of advantages, such as high degree of comfort for the user, friction and, thus, better retention in short shorts and aesthetically attractive appearance.

Barrier layer 104 to the liquid is not permeable to liquid material. Examples of such layers of material are thin plastic films and coatings of resin, wax, not permeable to liquid adhesives or similar materials.

Absorbent e is ement 105 consists of two parts, that is, of the first part, which is the region 106 of the accumulation of liquid absorbent element 105, and the second part, which is relatively thin and is made in the form of one or more layers of material that are essentially over the entire surface of sanitary pads. When using sanitary pads 101 it is placed in the genital region of the user, when this part is located in the area of the mouth of the vagina of the user. In the result of the selected body fluid will meet sanitary pad 101 within a limited and largely predetermined space sanitary pads, which is known as the humidified space. The location area 106 accumulation of fluid elect so that it coincided with the projected area of the humidification sanitary pads 101. Region 106 of liquid accumulation, therefore, is significantly smaller than a sanitary pad as a whole. However, due to the fact that the region 106 of the accumulation of liquid is located in the irrigated area sanitary pads, essentially all secreted by the body in a sanitary pad, the liquid will be held in the region 106 of the accumulation of liquid and absorbed her. Thus, it is extremely important to the region 106 of the accumulation of liquid had sufficient will the ban ability to absorb the expected number allocated by the body fluid. In this regard, the absorption capacity in the region 106 of the accumulation of liquid should reach at least 75% and preferably at least 85% of the total absorption capacity of sanitary pads. Usually it is estimated that strip panties must have absorptive capacity, which is approximately 3-5 ml, and a sanitary pad must be able to absorb approximately 12-15 ml on products intended for use, for example, at night or pads used in case of incontinence, it may be desirable even greater absorbing capacity.

The second part 105 of the absorbent element is located as a layer between permeable to the liquid surface layer region 102 and 106 of the accumulation of fluid and serves as a layer for the transmission of fluids from permeable to the liquid surface layer 102 in the first part of the absorbent element region 106 of liquid accumulation. The second part of the absorbent element 105 also goes for the edge region 106 of the accumulation of fluid in the plane of the product around the entire periphery of the region 106 of the accumulation of liquid in this case is the area 107 secondary absorption around the area 106 of the accumulation of fluid.

Suitable absorbent materials for use in absorbent element 105 are, for example, whipped the pulp, the LOI associated fibers of the absorbent layers of fabric, absorbent foam, peat or similar materials. The absorbent element may also contain super-absorbent polymers, i.e. polymers that can absorb the amount of liquid in several times their own weight, forming a moisture-containing gel. The superabsorbents are usually in the form of particles, flakes, fibers, granules. Superabsorbers material can be used by itself or in conjunction with other absorbent material.

Materials in the area 106 of the accumulation of liquid, and accordingly the area of 107 secondary absorption mainly picked so that the area of liquid accumulation was more tanakaparou and/or have a higher hydrophilicity than the area 107 secondary absorption. Conceiveably material may be, for example, by compression of the compressible porous structure, such as fibrous wool, or selection of a material with small pores. In General we can say that the fibrous structure with a large proportion of fine fibers has a thinner capillaries than the fibrous structure with a large proportion of thick fibers. You can also use what is known as capillary fibers, i.e. fibers with an external capillary, to obtain vysokoimpulsnogo material. Accordingly, the difference in hydrophilicity may be on ocena either through chemical or physical treatment of the material, either through choice of materials, which initially have different hydrophilicity.

To achieve the desired effect quick passage of fluid in the region 106 of the accumulation of liquid, high absorptive capacity and ability to retain fluid in the area 106 of the accumulation of fluid and small or absent distribution of the absorbed liquid in the region of 107 secondary absorption, thus, it is necessary that the area 106 of the accumulation of liquid contained hydrophilic material with a high absorption capacity, such as cellulose fiber, superabsorbent material, whereas the material in the field of 107 secondary absorption may be selected from materials with low or very low absorptive capacity, such as fibrous wool from synthetic fibers. The material which has been found works particularly well as an absorbent material in the accumulation of fluid is obtained by a dry process cellulosic fibrous material, described in document WO 94/10956. The material which has been found works particularly well as secondary material absorption is a material based on a bulk, laid aerodynamic method associated with latex cellulose fibers with a density of most pain is it 125 g/m 3.

As noted, the region 107 of the secondary absorption surrounds region 106 accumulation of fluid around its entire periphery. As a result, the region 107 of the secondary absorption creates a security zone, which can detain and absorb small quantities of liquid or a separate liquid droplets, which meet sanitary pad outside the scope of the moisture. Due to the low ability to move the liquid region 107 secondary absorption prevents the liquid reaches the edges of the sanitary napkins and the appearance of leaks. Because the area 106 of the accumulation of liquid must have a greater absorptive capacity relative to its area, this area typically has a relatively high rigidity. Region 107 secondary absorption in this case is used for the additional purpose of education soft intermediate portion between the region 106 of the accumulation of fluid and the body of a user.

Can also be useful to further impede the flow of the fluids in the plane of the sanitary pads through the provision of sanitary pads by some form of barrier to liquid, which prevents the movement of fluid in the absorbent material or permeable to the liquid surface layer 102 to the brim sanitary pads. Examples of such barriers for liquid what are the seals, welded seams, strips, adhesive, plastic wrapping strips or funds that make a hydrophobic material such as wax or similar material. In this regard, barriers for liquid can be placed along the edges sanitary pads and/or along the edges of the field 106 for accumulation of fluid.

Sanitary pad 101 has a relatively wide front portion 114 and a much narrower rear portion 115. Sanitary pad 101 also has two side edges 109, 110, the main length of which falls in the longitudinal direction of the sanitary pads, and essentially transverse front edge 111 and the transverse rear edge 112.

When using sanitary pads 101 of the front part 114 is part of the sanitary pad that faces forward on the user and, therefore, will be placed on top of the genitalia of the user. The front part 114 tapering towards the rear portion 115, which is significantly narrower front part 114.

For a sanitary pad not been using so far back that it will be noticeable when worn with a narrow cowards, the rear part of the sanitary pads should have a length of from 80 mm to 140 mm, and the total length of sanitary pads should not exceed approximately 260 mm

To attached the Oia sanitary pads to short cowards on the outer side of the layer 103 backside sanitary pads are fastening means 116. The fastening means 116 is made in the form of longitudinal adhesive strips. Before using the fastening means 116 is protected in the usual way, for example, by a protective layer of paper or plastics, treated with silicone or sealed so that it is easily separated from the adhesive surface, when a sanitary pad should be used. Of course, the adhesive means may be arranged in any configuration suitable for this purpose. To minimize the impact of adhesive means on the permeability sanitary pads in the field of secondary absorption in this area should be used as little as possible adhesive, or the adhesive material should be in a discontinuous pattern, which provides breathability intermediate the exposed parts of the layer 103 backside. Alternatively can be used breathable mounting adhesive means at least within the area 107 secondary absorption. You can also use other types of fasteners, such as coating with high friction, push buttons, clips, fasteners, valves or the like. Another alternative is to mount sticky substance, which is attached to the user's body. Various types of fastening means can also to minirobot with each other. For example, widely used supply of sanitary pads as the mounting adhesive means on the back layer side, and the mounting of the vehicle.

Sanitary pad 101, shown in figures 1 and 2, can be produced efficiently and economically from continuous webs of material through the overlay layer of absorbent material is not permeable to liquid barrier layer, after which the areas of liquid connected with them is not permeable to liquid barrier layer is cut down or cut out from the laminated fabric and combined with the other components of the sanitary napkins.

Figure 3 and 4 shows a sanitary pad 301, containing permeable to the liquid surface layer 302, the layer 303 a rear side and an absorbent element 305, enclosed between the surface layers 302, 303. The surface layers 302, 303 are interconnected in edge parts 317 passing around the absorbent element 305. This edge connection can be made in the usual way by gluing, stitching or welding with heat or ultrasound.

Permeable to the liquid surface layer 302 may, as described in connection with figures 1 and 2, be made of any permeable to fluid material suitable for this purpose.

Layer 303 back side consists of a layer is not permeable to fluid the STI material. Examples of such materials are various types of thin plastic films or non-woven material treated to prevent penetration of liquid, for example, by coating with plastic, wax or other similar material. Not permeable to the liquid layer 303 backside may also be composed of not permeable to the liquid surface of the absorbent element 305. However, in this embodiment of the invention the layer of the back side cannot communicate with permeable to the liquid surface layer 302 edging connection around the absorbent element 305, but a sanitary pad 301 may be of a design similar to that described in connection with sanitary pad 101, shown in figures 1 and 2.

In the embodiment of the invention shown in figa, the absorbent element 305 has the same design as the absorbent element 105 shown in figures 1 and 2. The absorbent element 305, therefore, contains a region 306 accumulation of liquid and the region 307 secondary absorption, and the area of the secondary absorption made in the form of a layer of material which passes between permeable to the liquid surface layer 302 and region 306 accumulation of fluid. On Figg shows an alternative embodiment of the invention, in which the region wtorek the CSOs absorption is only in the same plane, as the area 306 accumulation of liquid and completely surrounds the area of the accumulation of liquid in the plane.

Although the absorbent element 305 is shown in the figures as made of two separate parts, you can perform the absorbent element 305 from one absorbent layer, which has high hydrophilicity, and/or more compact structure within the region 306 accumulation of fluid. A large absorbing capacity within the region 306 accumulation of fluid can also be caused by a larger amount of absorbent material in this area and/or add superabsorbents.

In order to make a sanitary pad 301 breathable within parts of the region 307 secondary absorption located around the periphery region 306 accumulation of liquid, they can be provided with perforations 318, which figa and 4b pass through the entire thickness of the sanitary pads. Alternatively, perforations 318 may pass through only part of the thickness of the sanitary pads 301, if at least not permeable to the liquid layer 303 backside perforated. In this regard, the perforations 318 can be performed, for example, piercing, stamping, punching or similar ways. Thanks to the perforation border around the area 306 accumulation of fluid, thus, produces the t sanitary pad with a Central impervious to the liquid absorbing part and the surrounding breathable safety zone.

As a sanitary pad 101, shown in figs 1 and 2, a sanitary pad, shown in figure 3 and 4, provided with fastening means in the form of strips 316 adhesive means located on a non-permeable to the liquid layer 303 backside.
