The scope of the invention

The invention relates to an absorbent article having a longitudinal direction and a transverse direction and containing permeable to the liquid surface layer that is not permeable to the liquid surface layer and the absorbent element located between the surface layer and the absorbent element contains compressible absorbent material layer.

Prior art

To capture and absorb the fluids produced by the body immediately after their selection, and to ensure a large absorbent capacity in the field of absorbent articles, which, supposedly, is subjected to wetting by liquids first, the usual is to provide absorbent articles of this type, which are described in the introduction, absorbent raised part. In this regard, it is important that raised part had such size and shape that are not turned it into a source of pressure or irritation of the body of the consumer.

In the European patent EP 0834296 described absorbent article containing layer that expands when wetted and because of that accepts a pre-specified form in thickness. In a known product may form a raised area in the region of the extended layer. The problem with this product C is enabled in ensuring the correct positioning initially essentially flat products relative to the body of the consumer. Incorrect location may result in that the liquid will not fall into the scope of the uplifted area, i.e. the raised section may not be used and its absorptive capacity will not be used. In this situation, the risk of leaks caused by loose fit and low absorbent capacity is inevitable. In addition, if the product is wrong, the raised area may take an uncomfortable position relative to the body of the consumer, which will lead to rubbing and other problems in inconvenience during use of the product.

In the European patent EP 0804917 described absorbent article containing an expanding layer with lots of cuts and holes that promote wetting of the expanding layer. The lack of absorbent products described in patent EP 0804917, is that the expanding layer creates a soft bulge, the size and shape of which are determined by the amount of liquid that has reached this layer. Therefore, it is impossible to provide the conditions under which the raised area would have a well-defined size and shape.

Description of the invention

Thus, a need remains for further improvement in absorbent articles, in particular, from the viewpoint of ensuring the correct positioning and significant others who leak which would not depend on the use situation. The objective of the invention is the creation of absorbent products that can be manufactured using a simple and rational methods of production, and which can be Packed in a compact manner, without compromising quality, and ability to perform the assigned function.

The absorbent product of this type mentioned in the introduction, manufactured through the use of the present invention, and this product is mainly due to the fact that the compressible absorbent material layer contains at least one fold is made in the longitudinal direction, and the fact that the fold is at least partially compressed, resulting in a compressible absorbent layer of material has a higher density in the region of the fold, than in the areas of compressible absorbent material layer, which are located outside the crease, the crease has the ability to swell when it is subjected to wetting and/or mechanical stress, and then at least partially returns to its original shape in an uncompressed state.

In accordance with the preferred implementation fold feature in the middle relative to the Central line in the longitudinal direction of the product.

When wetting absor youseo product area folds compressible absorbent layer of material, which is subjected to wetting, absorbs liquid and swells. Due to the location of the folds of compressible absorbent layer of material toward the permeable for liquid surface layer, the raised area is then formed on the side of the product available to the body of the consumer. Due to the fact that the raised area activate the wetting, the absorbent product takes shape during use in accordance with how it is positioned relative to the body of the consumer, resulting in a product takes shape, characteristic for each consumer. This also means that the raised area is formed where the product is wetted, i.e. that the location of the product in the longitudinal direction is less important. If the fold is on the side of the compressible material layer in the direction from the user during use of the product, it tends to expand in a direction away from the body of the consumer. This results in the channel designed to receive fluid directed to the consumer through which fluid can be withdrawn from the area that is wetted first.

Some consumers prefer absorbent products with a nearly flat surface. According to the invention it is possible to offer these consumers the absorbent product with a PLoS the second surface, but with enhanced absorbent capacity and improved capacity for distribution of fluid in the longitudinal Central part of the product. After expanding the compressed folds of material in the enlarged area has a higher absorbent capacity. This, therefore, means that after wetting the absorbent article made according to the invention, regardless of the direction in which the facing fold compressible layer of material relative to the body of the consumer, has a high absorbent capacity within just the area of the product, which can be believed to moistened mostly fluid, secreted by the body of the consumer in the product.

To form a raised area on the surface of the absorbent product, facing the user during use, the fold may have a width in the range of 5-10 mm Fold of such size swells when wetted and then forms a raised portion which has a sufficiently small width to possess the ability to grow within a small distance between the outer lips of the female genital organs consumer without causing discomfort in the form of pressure or rubbing. Due to the fact that the raised section extends between the lips of the genitals, they are somewhat apart, the resulting passage of fluid between the body of the consumer and the product improves.

For the formation of edge barriers or longitudinal edge of the protrusions may be made of longitudinal folds along the side edges of the product. Such folds can be made so that they are extended in either direction permeable to the liquid surface layer, or in a direction not permeable to the liquid surface layer. When the folds moisten and/or when they are subjected to mechanical stress, for example, when the user moves and the product operates by creating pressure and effort shear legs, folds swell and form a soft raised protrusions that fit snugly to the body of the user and prevent leakage of fluid in the lateral direction, skirting the edge of the product. As the folds have an absorbent capacity, they also have the ability to absorb any liquid that reaches the edges of the product.

A suitable material for the compressible layer of material is combed through the fibrous layer. Particularly suitable combed through the fibrous layer, consisting mainly of viscose fibers.

In accordance with one embodiment of the invention, the compressible layer of material has essentially the same thickness in the region of the folds, and related fields.

Before pressing the fold may be in the form of a single protrusion in cross section. The can is also to perform the fold so that to have two or more tabs in cross section.

In addition, between the compressible layer of material and is not permeable to the liquid surface layer may be a layer of material having the ability to distribute the liquid.

According to another variant implementation of the invention, the absorbent product according to the invention may contain a soft fibrous layer made of a material that flatten when wetted. This layer of material fitted between the compressible layer of material and is permeable to the liquid surface. Soft fibrous layer gives a pleasant and comfortable feeling to the consumer. When the layer of material is flattened when wetted, the decrease was offset by a corresponding increase in the volume of the compressible material layer. Consequently, it is possible to manufacture an absorbent article with a surface profile that is essentially remains constant during use of the product.

According to the invention the longitudinal fold products can be located on the surface of the compressible layer of material facing the permeable for liquid surface layer. In this embodiment, the fold so it is open at the bottom and is directed away from the body of the user during use of the product. By the location of the folds of the material so that the on time of use, it expanded towards permeable to the liquid surface layer and the body of the user, get the product on which during use is formed raised section, the form of which is consistent with the anatomical features of the body of the consumer in the area of the folds of material that is wetted by the liquid.

If for any reason it is desirable to keep the surface available to the body of the consumer, essentially flat or if it is desirable that only a limited swelling on the surface, have to the body of the user, then the formation of longitudinal folds can be made so that it is expanded in the direction of not permeable to the liquid surface layer, so that it is the so-called open part was converted to permeable to the liquid surface layer and part in the form of a ledge was converted to non-permeable to the liquid surface layer. Such formation of folds provides absorbent ability, but has no effect at all or has only a minor influence on the shape of the surface of the product available to the body of the consumer. The relationship between morphology and absorption properties can also be adjusted through the use of products containing two or more folds that are located so that they are extended in different directions.

It is also possible to stabilize the fold of the strips is of her in a compressed state by water-soluble glue. After wetting folds glue is dissolved, and the fold may swell. The fold can also be stabilized, for example, by thermal bonding or other types of fasteners, collapsing in a time when the fold is subjected to mechanical stress. Such bonding can be successfully used in the folds along the side edges of the product, where the folds are subjected to pressure and efforts shift from the effects of the hips of the user and where you can expect only small quantities of liquid.

Method(s) of carrying out the invention

Figure 1 shows the workpiece 101 to an absorbent structure, which is intended for inclusion as a component in an absorbent product such as a sanitary pad, the pad in panties, strip for those suffering from incontinence or diaper. The workpiece 101 is composed of compressible absorbent fibrous material, compressible absorbent foam or similar material and has a longitudinal crease 102 material. Suitable for these purposes compressible absorbent fibrous material can be, for example, the fibrous layers comprising mainly the cellulose fibers, such as cellulose fluff pulp, cotton, rayon. Especially preferred combed fiber canvases of viscose fibres. Suitable compressible absorbent foams may serve absorbent cellulose foam, polyurethane foam.

Figure 2 shows the workpiece 101, presented in figure 1, after pressing. The workpiece 101 is pressed so that takes essentially flat shape. This means that the fold 102 material is pressed so as to form an elongated Central strip 103, which has a higher density than the portion 104 of the workpiece 101, located on each side of the strip.

Figure 3 shows a cross-section of the absorbent workpiece 301 in which an elongated fold has an alternate form. Blank 301 is shown in the form as it looks before pressing, and in cross section has three tabs, or three folds, as shown in the figure.

After pressing the workpiece 101, 301, shown in Fig.1-3, can be used as a component in a specific configuration of absorbent products, as shown in Fig.4-10.

Sanitary pad 400 shown in Figure 4 and 5, is of essentially conventional construction and therefore contains permeable to the liquid surface layer 405 that is not permeable to the liquid surface layer 406 and the absorptive element 407, enclosed between the surface layers 405, 406. Two of the surface layer 405, 406 have essentially the same form as the absorbent element 407, but few extend beyond edges of the absorbent element 407 in the plane of the sanitary pads and are connected to each other at the edges 408 around the entire contour of the absorbent element 407. This regional connection 408 may be performed, for example, by sizing, stitching or welding by heat or ultrasound. Permeable to the liquid surface layer 405 can be made of any material suitable for this purpose. Examples of commonly used is permeable to the liquid surface materials are various types of thin non-woven material, perforated plastic film, net material, permeable to liquid foam. Permeable to the liquid surface layer 405 can be made of two or more different materials to provide different functions of the surface layer. For example, normal is the location of the transmitting liquid layer for receiving the liquid layer. Also known arrangement of materials of different types in different parts of this surface sanitary pads that come to the body of the user during use. Therefore, the material is a high capacity fluid intake can be successfully located on that site sanitary pads, which, supposedly, is moistened first mostly fluid, secreted by the body, while the areas of the surface layer that mainly on the assumptions that must be a contact surface adjacent to the body of the user, is made of a material that is optimal to ensure softness and comfort to the skin of the consumer.

Not permeable to the liquid surface layer 406 may also be composed of any suitable not permeable to liquid material. Particularly favorable materials are thin plastic film which is permeable to liquid non-woven materials or materials covered not permeable to liquids substance, such as wax, resin, glue. You can also use laminates of not permeable to liquids materials. It may be desirable, for example, providing the rear side of the product outer layer of a textile nature, for example a layer of nonwoven material. Such non-woven material provides a soft, pleasant to the skin of the textile surface and the advantage of a high degree of user comfort, and a large coefficient of friction and, thus, the best retention in the underwear of the user. In addition, it is often considered that the textile surface has an aesthetically pleasing appearance. So the e is often a positive factor, if not permeable to the liquid surface layer 406 breathe, i.e. allows entry of gas and water vapor through the material layer.

Transmitting liquid layer 409 have between permeable to the liquid surface layer 405 and the absorbent element 407. Transmitting liquid layer 409 performs a variety of functions. For example, the transmitting liquid layer 409 receives fluid secreted by the body in a sanitary pad, and then passes the fluid to the absorbent element 407, located below. Therefore, it is reasonable to transmitting liquid layer 409 has been relatively bulky and had a microporous structure, which is the ability to rapidly accept and temporarily hold the selected liquid. Transmitting liquid layer 409 must also possess a lower density and/or to be less hydrophilic than the absorbent element 407, so that the liquid is preferably transmitted in the direction from the transmitting liquid layer 409 to the absorbent element 407, and not the other way. In the result, the transmitting liquid layer 409 also serves as an insulating layer, which creates a gap between the liquid is absorbed absorbent element 407, and the body of the consumer. In addition, the transmitting liquid layer 409 reduces the visual impression from the liquid absorbed the absolute is birouk element, what is often desirable, especially with regard to hygienic pads. Another advantage of the location of the permeable layer between the liquid surface layer 405 and the absorbent element 407 is that the transmitting liquid layer 409 often consists of a material which is air and compressible in comparison with absorbent element 407 and soft and supple against the body of the consumer, resulting in increases comfort and reduces the risk of rubbing and other skin irritations consumer.

Sanitary pad 400 essentially has the shape of an hourglass with the wider end sections 410, 411 and narrower perineal area 412 located between the end sections. Sanitary pad also has the middle line 413, passing in the longitudinal direction, two side edges 414, 415, passing in the longitudinal direction and concave in the direction of the middle line, and two end edges 416, 417 passing essentially in the transverse direction.

In the version presented on Figure 4 and 5, the absorbent element 407 consists of two parts 418, 419. The top absorbent portion 418 is located directly behind the transmission fluid layer 409, between the latter and the lower absorbent part 419. The top absorbent portion 418 is made of pressed blanks of this type which is represented in figure 1-3, and is essentially rectangular in shape with a longitudinal pressed pleat material 402. The lower absorbent element 419 appropriately consists of one or more layers of material with high absorbing ability, for example, fluff pulp, absorbent bonded fibrous layers, layers of creped paper, absorbent foam, peat bog moss. The absorbent element 104 may also contain overabsorbed polymers, i.e. polymers having the ability to absorb fluid, the mass of which exceeds several times their own weight, and forming a gel containing liquid. Overabsorbed substances are typically implemented in the form of particles, flakes, fibers, granules. Overabsorbed substances can be used alone or together with other absorbent materials. Layers of cellulose fibers with high density suitable for the formation of the lower absorbent portion 419. Bulk density of material is preferably at least 150 g/DM3. Material with good absorption properties, which is particularly suitable for use in the lower absorbent portion is cellulosic fibrous material formed by the dry method described in international application WO 94/10956.

In order to zafa keravat sanitary pad in panties, use 420 mount, located on the outer side is not permeable to the liquid surface layer 406 sanitary pads. Means 420 of the fastening is made in the form of a longitudinal zone of self-adhesive substances. To use the tool 420 fastening protected in the usual way, for example, by covering them with a protective layer of paper or plastic, treated with silicone or embossed so that it can be easily separated from the adhesive layer, when a sanitary pad ready for use. The adhesive may, of course, is in the form suitable for the purpose of illustration. Can also be used and other types of fastening means, such as coating with high friction, press buttons, clips, wings for fastening. Various types of fastening means can be also used in combination with each other. It is usual, for example, provision of sanitary pads as glue for fastening on the back and wings for fastening.

When using sanitary pads 400 it is fixed in the perineal part of the panties of the user by means 420 of the fastening. Figure 6 shows a simplified cross-section of sanitary napkins, are presented in figure 4 and 5, when she is in panties 422 consumer 421. Therefore, only the VA of the surface layer 405, 406 and the absorbent element 407 is depicted in the figure. To simplify the figure, the absorbent element 407 is shown as a continuous element. Figure 6 shows what happens when a sanitary pad moistened, and fluid produced by the body are received in the upper absorbent part 418. While the released fluid absorbed by the top absorbent part 418, the latter swells and longitudinal fold 402 material is returned at least partially to its original nepressovannaya form. Thus is formed the raised section 423, which has a maximum height in the main area of the wetted zone and which takes the form consistent with the form of the body of the consumer in wetted areas. This means that the raised area is located next to the body of the consumer 421 at the vaginal opening and may seize and absorb an additional amount of body fluid once the fluid is secreted by the consumer. Thus the risk of leakage is significantly reduced. Due to the fact that during use a sanitary pad takes the form specific to each user, it is particularly convenient for the consumer and provides a high degree of protection against leakage. Also, less importantly, have a sanitary pad in Trou is the IKI, and a small offset in the longitudinal direction, thus, does not cause adverse effects up until observed within the protective characteristics of sanitary pads, to prevent leaks. The invention also allows the user to choose individually how should be located a sanitary pad in panties. For example, in the case of use at night or in other cases, when the consumer is constantly in bed, it may be desirable to place a sanitary pad is slightly more shifted back in panties, than usually, when a sanitary pad use in the daytime.

Sanitary pad 700, shown in Fig.7 and 8, and as a sanitary pad, shown in figure 4-6, made with absorbent element 707, which is located between permeable to the liquid surface layer 705 and is not permeable to the liquid surface layer 706, which are interconnected along the edge connections 708.

As a sanitary pad depicted in Fig.4-6, a sanitary pad, shown in Fig.7 and 8, has essentially the shape of an hourglass with the wider end sections 710, 711 and narrower perineal area 712, located between the leaf sections 710, 711. Sanitary pad also has continued the strong middle line 713, two longitudinal side edges 714, 715 and two transverse end edges 716, 717.

Sanitary pad 700 is also provided with means 720 fasteners for fixing sanitary pads in panties consumer.

Sanitary pad 700 includes a longitudinal middle fold 702 material, which runs along the middle line 713 between the end edges 716, 717 almost the entire length of the sanitary pads. In addition, a sanitary pad has two additional longitudinal folds 725, 726 material that run along the side edges 714, 715 in the perineal area 712 sanitary pads. Before using folds 702, 725, 726 material is pressed, and a sanitary pad then has an essentially flat shape. When a sanitary pad moistened and folds 702, 725, 726 material absorbs the liquid, the folds of material to swell and at least to some extent restore their appearance before baling. In the humid regions of Central folds 702 is formed medium raised section 723, and along the side edges 714, 715 are formed the raised ledges 727, 728, where the liquid reached the folds 725, 726, located along the side edges. Thus, a sanitary pad 700 during use takes the form consistent with the anatomical features of the ate user, and, in addition, contains elevated absorbent barriers preventing leakage along the side edges 714, 715, as shown in cross-section on Fig. Due to the fact that the absorbent element 707 sanitary pads equipped with three folds 702, 725, 726 material in the perineal area 712, this site is narrower than the two end section 710, 711, where there is only a Central fold 702. Folding the absorbent element 707, therefore, also contributes to making the hygienic lining anatomically suitable right shape in the plane of the sanitary napkins.

Figure 9 shows a sanitary pad according to a variant implementation of the invention, which was pressed only part of the average longitudinal folds 902. Sanitary pad 900 is of the usual construction and includes an absorbent element 907 concluded between permeable to the liquid surface layer 905 and is not permeable to the liquid surface layer 906, which are interconnected along the edge connections 908. Sanitary pad 900 has the shape of an hourglass and contains the rear section 910, the front section 911 and a narrower intermediate perineal area 912.

As can be seen from the drawing, the portion of the Central fold 902, which is located within the rear section 910 sanitary pads, not the JV is assouan and forms a raised area 930 within the rear section 910 sanitary pads. This raised area 930 is used as a tool for the correct positioning of the product and provides the opportunity for the consumer to correctly place a sanitary pad in the transverse direction. The raised section 930 is also protection against liquid flowing back into the groove between the buttocks of the user.

Figure 10 and 11 shows the cross-section of sanitary pads 1004, in which the folds of the absorbent material in the element 1007 is used to, on the one hand, to give a hygienic pad 1004 anatomically acceptable form, and on the other hand, to provide additional absorbent capacity in the middle part of the absorbent element 1007.

As a sanitary pad, shown earlier, a sanitary pad, presented in Figure 10 and 11, contains permeable to the liquid surface layer 1105 and is not permeable to the liquid surface layer 1106 and the absorbent element 1007, enclosed between the surface layers 1005, 1006. Sanitary pad is also provided with means 1020 fastening. The absorbent element 1007 contains the first absorbent layer 1009 and the second absorbent layer 1018, with three located in the center of the longitudinal folds 1002, 1025,1026.

As shown in Figure 10, the first absorbent layer 1009 is made with a greater thickness in the Central is part of sanitary pads, resulting in a sanitary pad is located in the middle part of the raised section 1035. The first absorbent layer 1009 is made from a material that is flattened at wetting, as described in the Swedish patent SE 9604226-2. The second absorbent layer 1018 has a first fold 1002 that the open part toward non-permeable to the liquid surface layer 1006, and a part of it in the form of a ledge facing permeable to the liquid surface layer 1005. On each side of the first fold 1002 are additional folds 1025, 1026, which are parallel to the first fold 1002, but which are made in the opposite direction, i.e. open portions facing permeable to the liquid surface layer 1005, and parts in the form of tabs is not permeable to the liquid surface layer 1006.

When a sanitary pad 1000 shown in Figure 10, is subjected to wetting, on the one hand, the moistened area of the first absorbent layer 1009 is flattened and loses thickness, and on the other hand, folds 1002, 1025, 1026 swell. While the cross-section of sanitary pads 1000 takes the form shown figure 11. Therefore, a sanitary pad will have roughly the same profile shape after wetting, which she had when she was in the dry state, because nebuchan the e first fold 1002 coincides with the flattening of the first absorbent layer 1009, so the average longitudinal raised section 1035 remains on the surface of the sanitary pad, which is covered with permeable to the liquid surface layer 1005.

Folds 1025, 1026, located on each side of the first fold 1002, swell direction from permeable to the liquid surface layer 1005 and not have a detrimental impact on the shape of this surface sanitary napkins, available to the consumer, and serve only to provide an absorbent capacity in this area sanitary pads that can, supposedly, be wetted allocated by the first liquid.

Although the invention is described above with sanitary pads, it is, of course, can be used in absorbent articles, such as gaskets for those suffering from incontinence, diapers and pads in panties.

The various components described in connection with different variants can be combined within the scope of the invention. Therefore, a sanitary pad, shown in Fig.7 and 8, may be, for example, equipped with a transmission fluid layer and/or flatten the layer, as described in connection with Figure 4-6 and Figure 10 and 11 respectively. Transmitting liquid layer 409, shown in Figure 4-6, can be excluded as well as flatten the layer, shown in Figure 10 and 11. EN is a logical way sanitary pad described figs.4-6, may be provided to flatten the layer, and a sanitary pad, shown in Figure 10 and 11 may be equipped with a transmission fluid layer. And finally, of course, is not necessary for the invention that the absorbent product was in the form of an hourglass, as shown in the figures, but the invention can also be applied to the absorbent articles of other shapes, for example rectangular, triangular, trapezoidal, oval.
