Description

State of the art

The present invention relates to absorbent articles that are adapted to retain body exudates. More specifically, the present invention relates to disposable absorbent articles similar to underpants that have re-fastening lateral connecting seams.

It is known that modern disposable absorbent training pants for children undergoing the toilet training phase are a particularly suitable and useful product. Such training pants typically comprise an absorbent base including a moisture-proof outer element, a moisture-permeable element facing the body, and an absorbent structure. In addition, training pants include elastic side bands that are constantly connected to opposite side edges of the absorbent base. Thus, the base and side stripes form one hole for the waist and two holes for the legs.

The components of traditional training pants are constantly connected to each other with the formation of the finished product. These products are especially attractive for caregivers, and are useful for accustoming to using the toilet, as the underpants look very similar to clothing. Children consider diapers to be babies, and most children do not want to be considered babies and do not want to look like babies. Therefore, these children do not want to wear diapers for babies and prefer to wear training pants that look like underwear for adults. Thus, the transition from a traditional diaper to training pants that look more like clothes or underwear can be an important stage in the process of accustoming to using the toilet.

However, one drawback of modern training pants is that the methods of putting them on are limited to pulling, performed as pulling ordinary pants. Putting on a product that is performed as putting on underpants is in many cases convenient and especially suitable for active, walking children. However, even for the same child, a situation may arise when it would be useful to wear the product like a diaper. For example, it may be more convenient to wear a product like a diaper when it is advisable not to remove your baby’s shoes. Since it is difficult to predict when a particular method of putting on a product will be required, it is preferable to have a product that could be used both as a diaper and as a panty. This is preferable to having both types of products. A product that can be worn both as a diaper and as a pant makes it easy to check the condition of the inside of the product without pulling the product down.

Thus, it would be preferable to have a disposable absorbent article, which would be a traditional training pants, looking like clothes or underwear, and which would provide the opportunity to wear it as a diaper, and as underpants.

SUMMARY OF THE INVENTION

In response to the aforementioned need in the art, a new, coward-like disposable absorbent article has been discovered, including side fastening fastening closures with re-fastening. The absorbent article includes a fastening system that can be repeatedly fastened, unfastened and re-fastened. Re-fastening fastening seams formed by the fastening system components are arranged along the sides of the absorbent product for convenience and to make them look like clothing and comparable to the usual training pants, and to ensure a fit and comfort comparable to that provided by traditional training pants underpants, elastomeric side strips can be positioned on either side of the fastener seams.

In one implementation, the present invention relates to an absorbent article comprising an absorbent base that has a longitudinal axis, a transverse axis, front and rear waist edges parallel to the transverse axis, opposite side edges located between the front and rear waist edges, the front waist portion adjacent with a front waist edge, a back waist portion adjacent to a rear waist edge, and a gusset that is located between the front and rear waist parts and connects these parts. The front waist section has two laterally opposite front side strips and a front center stripe located between the front side strips and connecting these strips. Similarly, at the rear waist portion there are two laterally opposite lateral stripes and a rear center strip located between the rear side stripes and connecting these stripes. At least one pair of side strips is elastomeric in a direction usually parallel to the transverse axis. The absorbent base includes an element facing the body, an outer closure element connected to the element facing the body, and an absorbent system located between the element facing the body and the outer closure element. The absorbent article also includes a fastening system designed to make the absorbent article look like a coward by detachably connecting. The fastening system includes first and second fastening components located on the rear side strips and adapted to detachably disconnect the first and second mating fastening components located on the front side strips. In addition, the distance between the first and second fastened components in the transverse direction is basically equal to the distance between the first and second paired fastened components in the transverse direction.

The fastening components and the associated fastening components form re-fastening fastening fastening seams intended for fastening the front and back waist parts to each other. Fastened with the possibility of re-fastening the connecting seams allow you to stretch the product like underpants, or put it on like a diaper. If the training pants are soiled during use, the fastening component can be disconnected from the mating fastening component to make it easier to remove the training pants from the waist of the wearer with a reduced risk of unwanted contamination of the clothes and legs of the wearer. In addition, the fastening components can also be easily detached from the mating fastening components to inspect the training pants in order to detect possible contamination. Thus, the training pants are configured so that they can be pulled on the user’s hips or pulled away from them like regular training pants, and by disconnecting the first and second fastening components, they could be easily put on or removed like regular diapers. In addition, after the training pants are pulled over the legs and hips of the user, if necessary, you can change the position of the first and second fastened components.

The design of the absorbent base and fastening components provides an absorbent product with a fastening system that is resistant to accidental separation of the fastening components. The location of the re-fastening fastening joints on the sides of the wearer on his hips is particularly preferred since this is the area of the absorbent article that is least affected by the wearer's movements, such as leg movements in the joints. The re-fastening lateral fastening joints have certain advantages over the front fastening design, which is more susceptible to the forces arising from bending at the waist and movements of the user's legs. In addition, in specific implementations, elastic bands can be placed on both sides of the re-fastening fastening fasteners on both sides of the fastening to prevent the fastening components from being affected by stresses and strains resulting from body movement. In this case, the role of elastic bands in weakening the effect of stress and strain on fastened components is similar to the role of shock absorbers. In addition, the arrangement of reusable fastening connecting seams on the sides of the user gives the product a look similar to that of clothing, and is convenient for operating with fastening components. In addition, the components of the fastening system can be included in the absorbent product without covering the existing pattern of the outer closure element, which in modern training shorts has become an important feature of the interactive method of accustoming to using the toilet.

All side strips of the absorbent article have an end waist edge parallel to the transverse axis and forming part of one of the waist edges, as well as an opposite end foot edge. In specific implementations, each side strip is elastomeric in a direction parallel to the transverse axis in the region from the end waist edge to the end foot edge, which ensures that the product automatically snaps against the user.

In another implementation, the present invention relates to an absorbent article comprising an absorbent base that has a longitudinal axis, a transverse axis, front and rear waist edges parallel to the transverse axis, opposing side edges located between the front and rear waist edges, the front waist portion adjacent with a front waist edge, a back waist portion adjacent to a rear waist edge, and a gusset that is located between the front and rear waist parts and connects these parts. The absorbent base includes a rectangular composite structure that has opposing linear lateral edges parallel to the longitudinal axis, and opposing linear end edges parallel to the transverse axis. The compositional structure includes an element facing the body, an outer closure element connected to the element facing the body, and an absorbent system located between the element facing the body and the outer closure element. The absorbent article also includes first and second front side bands associated with the composite structure in the front waist portion, and first and second rear side bands associated with the composite structure in the rear waist portion. A fastening system for connecting an absorbent article to be detachable to form a panty-like configuration includes first and second fastening components associated with respective first and second rear side strips that are given the ability to detachably connect to the first and second mating fastening components associated with the respective first and second front side stripes. The absorbent article also includes elastomeric components located transversely between the fastened components and the absorbent system. In this implementation, the distance in the transverse direction between the first and second fastening components is basically equal to the distance in the transverse direction between the first and second mating fastening components.

This implementation of the present invention provides an absorbent article that is excellent for high speed manufacturing processes. This composite structure can usually be formed as a rectangular structure with elastomeric front and rear side strips connected to the composite structure by their waist end edges forming parts of the front and rear waist edges of the absorbent article.

In yet another implementation, the present invention relates to an absorbent article comprising an absorbent base and a fastening system for joining to detach the absorbent article to form a panty-like configuration. The absorbent base includes a rectangular composite structure containing the first and second elastomeric side bands associated with the composition structure in the first waist portion, and the first and second elastomeric side bands associated with the composite structure in the second waist portion. The substrate parts are connected with the first and second elastomeric side strips in the second waist part and extend laterally from these strips. The fastening system includes first and second fastening components located on the substrate parts and capable of releasably detaching the first and second mating fastening components located on the respective first and second elastomeric side strips in the first waist portion. The elastomeric side strips of the first waist part are offset longitudinally from the elastomeric side strips of the second waist part, and the width of the elastomeric side strips of the first waist part is the same as the width of the elastomeric side strips of the second waist part. This implementation provides an absorbent article with a lateral fastening system and equal width side strips located in opposite waist parts.

In yet another implementation, the present invention relates to a disposable absorbent article comprising an absorbent base and a fastening system for releasably attaching a front waist portion of an absorbent base to a rear waist portion of an absorbent base to form panties that can be fastened with a second fastening. Re-fastening briefs include a waist opening and two leg openings and include two elastomeric front side bands made of non-woven material and extending from the waist opening to each leg opening; two elastomeric rear side strips made of non-woven material and extending from the waist hole to each leg hole; two re-fastening fastening seams extending from the waist opening to each leg opening, and each re-fastening fastening seam located between the elastomeric front side strip and the elastomeric rear side strip; and two elastomeric leg parts that partially surround each leg opening.

This implementation of the present invention provides a disposable absorbent article that provides body fit and comfort comparable to conventional training pants and provides the added benefit of re-fastening fastening. The elastomeric side bands are typically located above the wearer's hips and provide elasticity in areas from the waist hole to each leg hole. The absorbent article fits snugly against the wearer's body due to a combination of elastomeric front and rear side bands and elastomeric foot parts. To hold the absorbent article firmly on the user, it is preferable that the re-fastening fastening joints are located in areas from the waist opening to each leg opening.

Re-fastening fastening joints are formed when the first and second fastening components are connected to the first and second mating fastening components. Preferably, the re-fastening fastening joints are relatively thin, narrow and elastic so that they look and feel like clothes made from fabric. Thus, in particular embodiments, re-fastening fastening joints have a length to width ratio of about 2 or more, such as from about 2 to about 25, in particular about 5 or more, such as from about 5 to about 8 Re-fastening fastening joints have a length and width that is perpendicular to the length. In particular, for a child weighing from about 9 to about 15 kg (20-34 pounds), it is preferable that the length is from about 5 to about 13 cm, for example about 10 cm, and the width is from about 0.5 to about 3 cm, for example, about 2 cm. It is preferred, although not necessary, that the length can be arranged substantially parallel to the longitudinal axis of the absorbent article, and the width may be located substantially parallel to the transverse axis of the absorbent article. The term "substantially parallel" in the present invention refers to an angle with the specified axis equal to not more than about 35 ° or less, preferably to an angle with the specified axis equal to not more than about 20 ° or less.

The fastening components may be any re-fastening fasteners that are suitable for use in absorbent articles, although it is preferable that they are mechanical fastening elements rather than sticky fastening elements for improved performance. Suitable mechanical fastening elements can be made by joining shaped materials such as containing hooks, loops, pear-shaped elements, mushroom-shaped elements, arrow-shaped elements, balls on legs, mating components, brackets, latches, and the like. In specific implementations, fastening components and mating fastening components are fastening components such as Velcro, containing loops and hooks. One skilled in the art will appreciate that the shape, density and polymer composition of the hinges and hooks can be selected so as to provide the necessary degree of fastening of the fastened components and the associated fastened components. A more firmly fixed material with hooks can be a material with a longer average hook length, a larger proportion of hooks oriented in a certain direction, or more strongly hooked hooks.

As disclosed in the simultaneously pending U.S. Patent Application Serial No. 60/112709, filed December 18, 1998, S.P. Olson et al. titled “Absorbent Articles Having Differential Strength Refastenable Seam”, the re-fastening fastening joint may include one or more re-fastening main joining zone and one or more re-fastening joining zone having enhanced bonding ability. The main and reinforced binding ability re-fastening fastening zones can be made to provide varying degrees of binding and in particular enhanced binding capacity in areas affected by more significant separation forces.

As disclosed in U.S. Patent Application Serial No. 60/112775, filed December 18, 1998, S.P. Olson titled “Absorbent Articles Having Hinged Fasteners”, re-fastening fastening joint may include separate connecting pieces of material separated by narrow gaps. Narrow gaps form the bending section necessary to improve the fit and fastening of the fastened components.

The disclosed absorbent articles are adapted to be worn close to the wearer's body in order to absorb and retain various exudates released from the body. In order to provide the user with a panty-like product, it is preferable that the absorbent product be pre-fastened. This product can be pulled like a regular training pants and then check its condition or remove it with the same ease as a product like a diaper. In order for the absorbent article to maintain the configuration of the underpants before the user deliberately unfastens the fasteners, additional fastening means, such as easily tearing point connections, can be used.

The fastening system makes it easy to inspect the inside of the product, similar to underpants. If necessary, this fastening system also allows you to quickly and easily remove your underpants. This is especially useful when there is unpleasant excrement in your underpants. If necessary, the carer can completely remove the product, similar to underpants, and replace it with a new one, without removing the child’s shoes and clothes. This fastening system using mechanical or adhesive fasteners can be used in a wide variety of absorbent products, including training pants, diapers, incontinence clothing and other types of clothing.

A detailed description of the design and construction of one form of training pants is given in US Pat. No. 4,940,464, issued July 10, 1990 to Van Gompel et al., Which is incorporated herein by reference. In the patent, Van Gompel et al. various materials are described from which training pants can be made, and a method for manufacturing training pants.

Detailed Description of Drawings

The basic provisions of the present invention can be used in relation to any suitable disposable absorbent article. Examples of such suitable products include diapers, training pants, personal care products for women, products intended for incontinence sufferers, other clothing intended for personal care and healthcare, and the like. To facilitate the explanation, the following description is given as an example of children's training pants.

1, a disposable absorbent article, such as training pants 20, is shown in a partially fastened state. Training pants 20 include an absorbent base 32 and a fastening system 80. The absorbent base 32 has a front waist portion 22, a rear waist portion 24, a crotch 26 connecting the front and rear waist portions, an inner surface 28 that is configured to contact the user, and an outer surface 30 opposite the inner surface, which is given a configuration that provides contact with the clothing of the user. Figures 2 and 3 show that in the absorbent base 32 there are also two longitudinally opposing lateral edges 36 and two laterally opposing waist edges, designated as the front waist edge 38 and the rear waist edge 39. The front waist portion 22 is adjacent with the front waistband 38, and the rear waistband 24 is adjacent to the rear waistband 39.

The absorbent base 32 shown includes a rectangular composite structure 33, two laterally opposing front side bands 34 and two laterally opposing rear side bands 134. As shown in FIG. 1, composite structure 33 and side bands 34 and 134 can be made as a whole or to represent two or more separate elements. The composite structure 33 shown includes an outer closure element 40, an element 42 facing the body (FIGS. 1 and 3) that is superimposed on and connected to the outer closure element, an absorbent system 44 (FIG. 3) that is located between the outer closure element and an element facing the body, and two holding valves 46 (figure 3). The rectangular composite structure 33 has opposing linear end edges 45 that form portions of the front and rear waist edges 38 and 39, and opposing linear side edges 47 that form portions of the side edges 36 of the absorbent base 32 (FIGS. 2 and 3). Figure 2 and 3 shows the arrows 48 and 49, which display the orientation, respectively, of the longitudinal axis and the transverse axis of the training pants 20.

When the training pants are in a fastened state, as partially shown in FIG. 1, the front and rear waist parts 22 and 24 are connected to each other and form pants in a three-dimensional configuration, which have a hole for the waist 50 and two holes for the legs 52. The front the waist portion 22 is a portion of training pants 20, which when worn is located in front of the user, and the rear waist portion 24 is a portion of training pants, which when worn is located behind the user. The crotch 26 of the training pants 20 is a section of training pants, which when worn is located between the legs of the user and covers the lower body of the user. The front and rear side strips 34 and 134 are sections of training pants 20 that are worn on the user's hips.

The front waist portion 22 of the absorbent base 32 includes transversely opposed front side strips 34 and a central front stripe 35 (FIGS. 2 and 3) located between the side strips and connecting them. The rear waist portion 24 of the absorbent base 32 includes laterally opposing rear side strips 134 and a rear center stripe 135 (FIGS. 2 and 3) located between the side strips and connecting them. The waist edges 38 and 39 of the absorbent base 32 are configured so that when worn, they surround the waist of the wearer and form a hole for the waist 50, which is characterized by the length of the outer border. Portions of laterally opposing lateral edges 36 typically form leg openings 52 in the area of the crotch 26.

The absorbent base 32 is configured to retain and / or absorb any exudates from the body. In particular, the absorbent base 32 preferably, although not necessarily, includes two retaining valves 46 that are configured to create a barrier to lateral exudation of the body. The elastic part 53 of the valve (FIG. 3) is operatively connected to each holding valve 46 by any suitable method known in the art. The holding valves 46, which have been elasticized, form an unattached edge, which acquires an upward, usually perpendicular configuration, at least in the area of the crotch 26 of the training pants 20 to form an insulating element near the wearer's body. The holding valves 46 may be located along the laterally opposite edges of the absorbent base 32 and may be located longitudinally along the entire length of the absorbent base or only along part of the length of the absorbent base. Suitable designs and arrangements of the holding valves 46 are well known to those skilled in the art and are described in US Pat. No. 4,704,116 issued November 3, 1987 to Enloe, which is incorporated herein by reference.

To further improve the retention and / or absorption of body exudates, as is known to those skilled in the art, it is preferred that the training pants 20 include a front waist elastic 54, a rear waist elastic 56 and elastic foot 58 (FIG. 3). The elastic waist members 54 and 56 may be operatively attached to the outer closure 40 and / or the body facing 42 along the opposing waist edges 38 and 39, and they may be located along part or all of the length of the waist edges. Preferably, the leg elastic members 58 are operatively attached to the outer closure member 40 and / or the body facing member 42 along the opposing side edges 36 and are located in the crotch region 26 of the training pants 20. Preferably, the leg elastic members 58 are located in the longitudinal a direction along each lateral edge 47 of the composite structure 33. Each leg elastic part 58 has a front end point 63 and a rear end point 65, which are the longitudinal sections of the elastic assembly carried out by the elastic foot parts. Preferably, the front end points 63 are located adjacent to the longitudinally innermost portions of the front side strips 34 and it is preferred that the rear end points 65 are adjacent to the longitudinally innermost portions of the rear side strips 134.

The elastic parts 53 of the valves, the waist elastic parts 54 and 56 and the foot elastic parts 58 may be made of any suitable elastic material. As is well known to those skilled in the art, suitable elastic materials include sheets, strands, or ribbons of natural rubber, synthetic rubber, and thermoplastic elastomeric polymers. These elastic materials can be stretched and glued to the substrate, glued to the assembled substrate or glued to the substrate, and then elasticized or shrunk, for example, by heat treatment, so that elastic tensile forces act on the substrate. In particular, in one particular implementation, the leg elastic parts 58 are a plurality of joined multifilament elastomeric strands consisting of dry spun polyurethane fibers sold under the trade name LYCRA® by E. I. Du Pont de Nemours and Company, Wilmington, Delaware, USA

Preferably, the outer closure member 40 is a material that is substantially watertight and which can be elastic, stretchable or non-stretchable. The outer closure element 40 may include a single layer of moisture-proof material, but it is preferable that it includes a multilayer layered structure in which at least one of the layers is moisture-proof. In particular, the outer closure member 40 may include a moisture-permeable outer layer and a moisture-proof inner layer, which are suitably bonded to each other using glue intended for the manufacture of laminated materials (not shown). Suitable adhesives intended for the manufacture of layered materials that can be applied in a continuous layer or onto periodically arranged areas in the form of droplets, by spraying, with the formation of periodically arranged curls, etc., are available from Findley Adhesives, Inc., of Wauwatosa, Wisconsin, USA or from National Starch and Chemical Company, Bridgewater, New Jersey, USA. The moisture-permeable outer layer can be any suitable material, and preferably one that usually gives a fabric-like texture. One example of such a material is a polypropylene nonwoven spunbond production method with a surface density of 20 g / m ² (grams per square meter). The outer layer can also be made of the material from which the moisture-permeable element 42 is made, facing the body. Although the outer layer does not have to be moisture permeable, it is preferable that it has a relatively tissue-like texture.

The inner layer of the outer closure member 40 may be moisture and vapor impermeable or may be moisture impermeable and vapor permeable. Preferably, the inner layer is made of a thin plastic film, although other flexible, moisture-proof materials can be used. The inner layer or the moisture-proof outer covering element 40, when it is single-layer, protects the product, such as sheets and clothes, as well as the wearer and caregiver from wetting with product secretions. A moisture-proof film suitable for use as a moisture-proof inner layer or a single-layer moisture-proof outer cover 40 is a 1 mil (1 mil = 0.0254 mm) polyethylene film sold by Edison Plastic Company of South Plainfield, New Jersey, USA. If the outer closure member 40 is a single layer of material, it can be embossed or matted to give an appearance that is more like a fabric. As noted above, the moisture-proof material may allow vapor to pass from the inside of the disposable absorbent article, but prevent liquid from passing through the outer closure member 40. A suitable “breathable” material consists of a microporous polymer film or non-woven material that is coated or otherwise processed to give it the necessary level of moisture resistance. A suitable microporous film is PMP-1 film material sold by Mitsui Toatsu Chemicals, Inc., Tokyo, Japan, or XCO-8044 polyolefin film sold by ZM Company, Minneapolis, Minnesota, USA.

As shown in figures 1 and 2, it is preferable that the training pants 20, and in particular the outer closure element 40, include one or more components that determine the appearance. Examples of components that define appearance include, without limitation, drawings; highlighted or underlined openings for the legs and for the waist, designed to make the shape of the product more clear or visible to the user; highlighted or underlined sections of the product designed to simulate functional components, such as elastic ribbons for legs, elastic ribbons for the waist, imitation of codpiece for boys, frills for girls; highlighted areas of the product intended to change the appearance and shape of the product; highlighted humidity indicators, temperature indicators, etc .; highlighted labels on the back or front of the product and highlighted written instructions on the relevant sections of the product.

Shown in the drawing, the training pants 20, which are designed for little girls, include a registered pattern 60 located on the outer covering element. In this model, the registered pattern 60 includes an imitation of a simple pictorial pattern 61, an imitation of waist frills 62 and an imitation of ankle frills 64. A simple pictorial pattern 61 includes a rainbow, the sun, clouds, animal images, a cart and balloons. You can use any suitable design of training pants designed for little girls, so that they are attractive from an aesthetic and / or comfortable from a functional point of view for them and for those who care. It is preferable that the components that determine the appearance, located on special areas of the training pants 20, which can be performed using the methods disclosed in US patent 5766389, issued June 16, 1998 Brandon et al., Which is incorporated into the present invention by reference. Preferably, a simple graphic pattern 61 is located on the front waist part 22 along the longitudinal centerline of the training pants 20.

The moisture permeable member 42 facing the body is presented as being superposed on the outer closure member 40 and the absorbent system 44 and may, but should not, be of the same size as the outer closure member 40. Preferably, the member 42 facing the body is flexible. soft to the touch and does not irritate the baby’s skin. In addition, the body-facing element 42 may be less hydrophilic than the absorbent system 44, so that a relatively dry surface adheres to the user and fluid is easily seeped through its entire thickness.

The body facing element 42 can be made from a wide variety of textile materials, such as synthetic fibers (e.g. polyester or polypropylene fibers), natural fibers (e.g. wood or cotton fibers), combinations of natural and synthetic fibers, porous foams, mesh foams perforated plastic films and the like. Various woven and non-woven materials can be used to make the body facing element 42. For example, an element facing the body may consist of a nonwoven material made from polyolefin fibers obtained by a spinneret method or an aerodynamic method from a melt. The element facing the body may also be a carded material made from natural and / or synthetic fibers. An element facing the body may consist of a primarily hydrophobic material and this hydrophobic material may not necessarily be treated with a surfactant or in another way to give it the necessary degree of wettability and hydrophilicity. In particular, the surface of the material can be treated with a solution of a surfactant concentration of 0.28 wt.%, Sold by Rohm and Haas Co. under the trade name Triton X-102. The surfactant can be applied by any conventional means, such as spraying, printing, brushing, and the like. The surfactant can be applied to the entire body facing element 42, or it can be applied selectively to certain areas of the body facing element, such as a middle portion located along a longitudinal center line.

A suitable moisture-permeable element 42 facing the body is a non-woven two-component material having a surface density of about 27 g / m ² . The nonwoven bicomponent material may be a bicomponent spunbond production method or a bicomponent material obtained from carding. Suitable bicomponent staple fibers include polyethylene / polypropylene bicomponent fiber manufactured by CHISSO Corporation, Osaka, Japan. In this particular bicomponent fiber, polypropylene forms a core, and polyethylene forms a fiber sheath. Other fiber orientations are possible, such as multi-leaf, parallel, butt-to-head, etc. Although the outer closure element 40 and the body facing element 42 may be elastomeric materials, for some implementations it may be preferable that the composite structure is generally inelastic, so that the outer closure element, the body facing element, and the absorbent system consist from materials that are usually not elastomeric.

The absorbent system 44 (FIG. 3) is located between the outer closure member 40 and the body facing member 42, and these components, as is well known in the art, can be connected to each other using any suitable means, such as adhesives. The absorbent system 44 may be any structure that is usually compressible, elastic, does not irritate the skin of the child, and is capable of absorbing and retaining fluids and certain secretions of the body. It is possible to make an absorbent system 44 of various sizes and shapes and to make it from a wide variety of liquid absorbent materials commonly used in the art. In particular, it is preferable that the absorbent system 44 includes a matrix of hydrophilic fibers, such as fine pulp material mixed with ground material having a high absorbency, commonly known as super absorbent material. In a specific implementation, the absorbent system 44 includes a matrix of micronized cellulose, such as micronized wood pulp, and a super absorbent micronized material forming a hydrogel. Fine wood pulp can be replaced with fibers from synthetic polymers of the spinneret production method or a combination of fibers of the spinneret production method and natural fibers. The ground superabsorbent material can be substantially uniformly mixed with hydrophilic fibers or may be mixed unevenly with them. To improve the retention and absorption of body exudates, finely ground cellulose and ground superabsorbent material can be selectively positioned in the required areas of the absorbent system 44. The concentration of the ground superabsorbent material may vary across the thickness of the absorbent system 44. Alternatively, the absorbent system 44 may be a laminate made of fibrous materials and superabsorbent material, or other suitable means of holding superpie can be used melting material in a limited area.

Suitable superabsorbent materials can be selected from among natural, synthetic and modified natural polymers and materials. Super absorbent materials can be inorganic materials, such as silica gels, or organic compounds, such as crosslinked polymers. Suitable superabsorbent materials can be obtained from various suppliers, such as the Dow Chemical Company located in Midland, Michigan, USA and Stockhausen GmbH & Co. KG, D-47805 Krefeld, Federal Republic of Germany. Typically, a super absorbent material is capable of absorbing an amount of water about 15 times its mass, and it is preferable that it is capable of absorbing an amount of water about 25 times its mass.

In one implementation, the absorbent system 44 is generally rectangular in shape and includes a mixture of finely ground wood pulp and superabsorbent material. The preferred type of micronized cellulose is a CR1654 product manufactured by Kimberly-Clark Corporation, Neenah, Wisconsin, USA, and it is a bleached, highly absorbent sulphate pulp containing mainly softwood fibers. Typically, the super absorbent material is contained in the absorbent system 44 in an amount of from about 5 to about 90 wt. % based on the total weight of the absorbent system. Preferably, the absorbent system has a density in the range of from about 0.1 to about 0.35 g / cm ³ . The absorbent system 44 may or may not be wrapped or wrapped in a suitable wrap of thin tissue that maintains the integrity and / or shape of the absorbent system.

The absorbent base 32 may also include other materials that are primarily designed to receive, temporarily hold and / or transfer fluid along opposed surfaces of the absorbent system 44, which increases the absorbency of the absorbent system. One suitable material is called a release distribution layer (not shown), which is a surface density of about 50 g / m ² , carded web material bonded by air blowing and a homogeneous mixture containing 60% 3-denier bicomponent fibers polyester sheath and polyethylene core sold by BASF Corporation, and 40% 6 denier polyester fibers sold by Hoechst Celanese Corporation, in Portsmouth, Virginia, USA.

As noted above, the training pants 20 shown in the drawing have front and rear side strips 34 and 134 located on both sides of the absorbent base 32. These transverse opposed front side strips 34 and the transverse opposed rear side strips 134 can be permanently connected with the composite structure 33 of the absorbent base 32 on the respective front and rear waist parts 22 and 24 and using the fastening system 80 to disconnect with each other. More precisely, as is better shown in FIGS. 2 and 3, the front side strips 34 can be permanently attached and transversely behind the linear side edges 47 of the composite structure 33 in the front waist portion 22 along the attachment lines 66, and the rear side strips 134 can be constantly attach and transverse behind the linear side edges of the composite structure in the rear waist portion 24 along the attachment lines 66. The side strips 34 and 134 can be attached using attachment means known those skilled in the art, such as adhesive, thermal, or ultrasonic bonding. Side strips 34 and 134 can also be made in the form of parts of components of the composite structure 33, such as an outer covering element or an element adjacent to the body.

The lateral bands 34 and 134 shown in the drawings have an outer edge 68 that is at some distance from the attachment line 66, an end foot edge 70 located closer to the center of the training pants 20 in the longitudinal direction, and an end waist edge 72 located further from the center training pants in the longitudinal direction. The end foot edge 70 and the end waist edge 72 extend from the side edges 47 of the composite structure 33 to the outer edges 68. The end foot edges 70 of the side bands 34 and 134 form part of the side edges 36 of the absorbent base 32. It is preferred, but not necessary, in the back waist parts 24 end leg edges 70 were located at some angle to the transverse axis 49 so that the area of the closed back of the pants was greater than the area of the closed front. Preferably, the end waist edges 72 are parallel to the transverse axis 49. The end waist edges 72 of the front side strips 34 form part of the front waist edge 38 of the absorbent base 32, and the end waist edges 72 of the rear side strips 134 form part of the rear waist edge 39 of the absorbent base.

In specific implementations, to improve fit and appearance, it is preferable that the side strips 34 and 134 have an average length measured in a direction parallel to the longitudinal axis 48, which would be about 20% or more, preferably about 25% or more of the total length of the absorbent article , also measured in a direction parallel to the longitudinal axis 48. For example, it is preferable that for training pants, the total length of which is approximately 54 cm, the side strips 34 and 134 have an average length of approximately 10 cm or more, such as about 15 cm. Although all side strips 34 and 134 extend from the waist hole 50 to one of the leg openings 52, when moving from the attachment lines 66 to the outer edge 68, the length of the rear side strips 134 is uniformly reduced, which is best shown in figure 2 and 3.

Each side strip 34 and 134 may include one or more specific and separate pieces of material. In particular, in specific implementations, all side bands 34 and 134 may include first and second sections of the side strip that are joined by seams, at least one of these sections being elastomeric material (see FIG. 7). Alternatively, each individual side strip 34 and 134 may include one piece of material that is folded along an intermediate folding line (not shown).

Preferably, the side strips 34 and 134 are elastic material capable of stretching in a direction substantially parallel to the transverse axis 49 of the training pants 20. In particular implementations, both the front and rear side strips 34 and 134 may include an inner portion 78 located between an outer edge 68 and a corresponding front or rear center strip 35 or 135. In the embodiment shown, the inner portions 78 are located between the outer edges 68 and the side edges 47 of the rectangular composite page 33. The elastic material of the side strips 34 may be located on the inner portions 78 to make the side strips elastomeric in a direction substantially parallel to the transverse axis 49. It is most preferred that each side stripe 34 is elastomeric in the portion from the end waistband 72 to the end foot edges 70. More preferably, all the individual pieces of material located between the end waist edge 72 and the end foot edge 70 parallel to the transverse axis 49, extending from attachment 66 to the outer edge 68 and having a width equal to 2 cm

Suitable elastic materials, as well as the process of incorporating elastic side bands into training pants, are described in the following US patents: 4940464, issued July 10, 1990, Van Compel et al .; 5,224,405 issued July 6, 1993 to Pohjola; 5104116, issued April 14, 1992 Pohjola; and 5,046,272 issued September 10, 1991 to Vogt et al., which are incorporated herein by reference. In specific implementations, the elastic materials are thermally drawn laminate (STL), cervical laminate (NBL), cervical laminate, or stretch-formed laminate (SBL). Methods for making such materials are well known to those skilled in the art and are described in US Pat. No. 4,663,220 issued May 5, 1987 to Wisneski et al .; U.S. Patent 5,226,992 issued July 13, 1993 to Mormon; and European Patent Application No. EP 0217032, published April 8, 1987 on behalf of Taylor et al., which are incorporated herein by reference. Alternatively, the sideband materials may be other woven or non-woven materials, such as those described above as being suitable for the manufacture of an outer closure member 40 or an element 42 adjacent to the body, or stretchable but not elastic materials.

Training pants 20 according to the present invention also include a fastening system 80 for securing training pants at a user's waist (FIGS. 2 and 3). The fastening system 80 shown in the drawing includes first and second fastening components 82 and 83 that are adapted to be re-connected to the first and second mating fastening components 84 and 85. In one implementation, one surface of the first and second fastening components 82 and 83 is a plurality of mating elements that protrude from this surface. The mating elements of these fastening components 82 and 83 are adapted to repeatedly engage and disengage with the mating elements of the mating fastening components 84 and 85.

In one particular implementation, the first and second fastening components 82 and 83 are hook and loop fastener parts, and the first and second mating fastening components 84 and 85 are pair of hook and loop fastener components. In another specific implementation, the first and second fastener components 82 and 83 are Velcro fastener parts having loops, and the first and second fastener fastener components 84 and 85 are paired Velcro fastener parts having hooks. Although the implementations shown show the rear waist portion 24 superimposed on the front waist portion 22, which is convenient, the training pants 20 can also be configured so that the front waist portion overlays the rear waist portion. The parts of the Velcro fastener having loops are usually fabric or material that has a base or a supporting structure and a plurality of loop-like elements protruding from at least one surface of the supporting structure. The loop material can be formed from any suitable material, such as acrylic, nylon or polyester, and can be formed by methods such as warp knitting, gluing stitches, or needle stitching. Such materials with loops are manufactured by Guilford Mills, Inc., Greensboro, North Carolina, USA under trade designation No. 36549.

Hook-and-eye fasteners are usually a fabric or material that has a base or support structure and a plurality of hook-like elements protruding from at least one surface of the support structure. Unlike fasteners with hinges, for which it is preferable that they are a flexible material, for a material with hooks, it is preferable to be an elastic material to minimize the unintentional release of the fastened components due to deformation of the material with hooks and its hooking on the fabric or other subjects. The term "resilient" in the present invention refers to a mating material having a predetermined shape and the ability to restore a predetermined shape after adhesion and disengagement from a conjugated, paired mating material. Suitable hook material can be molded or extruded from nylon, polypropylene, or other suitable material. Velcro Industries BV, Amsterdam, Netherlands and its affiliates under the names Velcro HTH-829 with unidirectional hooks at a thickness of approximately 0.089 mm (3 , 5 mil), and NTN-851 with a unidirectional arrangement of hooks at a thickness of approximately 0.051 mm (2 mil).

Figure 3 shows that the first and second fastening components 82 and 83 are preferably located on the outer surface 28 of the training pants 20 on the rear waist portion 24. It is preferred that the first and second fastening components 82 and 83 are located along the outer edges 68 of the rear side bands 134 and adjacent to the end waist edge 72 or were next to it. In particular, in some implementations, the first and second fastening components 82 and 83 are located at a distance of no more than about 2 cm, and more preferably at a distance of no more than about 1 cm from the outer edges 68, the end waist edges 72 and the end foot edges 70.

Figure 2 shows that the first and second mating fastening components 84 and 85 are located on the outer surface 30 of the training pants 20 on the front waist portion 22. The first and second mating fastening components 84 and 85 are made to be sized to connect with the first and second fastening components 82 and 83, and it is preferable that they are located along the outer edges 68 of the front side strips 34 and are adjacent to or adjacent to the end waist edge 72. In particular, in some implementations, the first and second mating fastening components 84 and 85 are located at a distance of no more than about 2 cm, and more preferably at a distance of no more than about 1 cm from the outer edges 68, the end waist edges 72, and the end leg edges 70. If the fastening components 82 and 83 are fasteners with loops located on the inner surface 28, and the paired fastening components 84 and 85 are fasteners with hooks located on the outer surface 30, then to close outward rigid hooks, fastening components that are larger than the size of the mating fastening components can be used.

In order for the re-fastening fastening connecting seams 88 to be located on the sides of the user, it is particularly desirable that the distance in the transverse direction between the first and second fastening components 82 and 83 is substantially the same as the distance in the transverse direction between the first and second mating fastening components 84 and 85. The distance in the transverse direction between the set of fasteners is the distance that is measured parallel to the transverse axis 49 between the longitudinal axial and lines of fasteners at the side strips 34 and 134 in unstretched condition.

The fastening components and the mating fastening components 82-85 can be attached to the side strips 34 and 134 by any means known to those skilled in the art, such as adhesive bonding, ultrasonic bonding or thermal bonding. In an alternative implementation (not shown), the training pants 20 include only one mating fastening component located in the front waist portion 22 and designed for fastening with the possibility of re-fastening components 82 and 83. In yet another alternative implementation, the fastening components and the mating fastening components may be areas constituting a whole with the side stripes. For example, the elastomeric front side strips 34 may act as mating fastening components, as they may include material that is capable of being detachably connected to the fastening components 82 and 83. It is preferred that the first and second mating fastening components 84 and 85 are rectangular, although alternatively, they may be square, round, oval, curved or have another non-rectangular shape.

When the fastening components and the mating fastening components 82-85 are detachably connected, the side edges 36 of the absorbent base 32 form leg openings 52 in the area of the crotch 26, and the waist edges 38 and 39 of the absorbent base, including the end waist edges 72 of the side strips, form an opening for the waist 50. In some implementations for improved formation of leg openings 52, it is preferred that the front side strips 34 are in the longitudinal direction at some distance from the rear side p olos 134 (see FIGS. 2 and 3). For example, the front side strips 34 may be longitudinally from the rear side strips 134 at a distance of about 20% or more, preferably from about 20 to about 60%, and more preferably from about 35 to about 60% full length of absorbent article.

In the connected state, the fastening components and the associated fastening components 82-85 form re-fastening fastening joints 88 (FIG. 1). In a particular implementation, all fastening components and mating fastening components 82-85 are characterized by a length in a direction substantially parallel to the longitudinal axis 48 of the absorbent pants 20 and a width in a direction substantially parallel to the transverse axis 49 of the absorbent pants. For example, for a child weighing from about 9 to about 15 kg (20-30 pounds), it is preferable that the length of the fastening components and the conjugate fastening components is from about 5 to about 13 cm, for example, about 10 cm and preferably, the width is from about 0.5 to about 3 cm, for example 1 cm. It is preferable that the fastening components and the mating fastening components have a length to width ratio of about 2 or more, preferably from about 2 to about 25, and most e preferably about 5 or more, for example from about 5 to about 8.

Preferably, when the fastening components 82-85 are in a fastened state, the re-fastening fastening joints 88 cover substantially the entire distance between the waist opening 50 and the leg openings 52. More preferably, the re-fastening fastening joints 88 could cover from about 80 to 100%, and particularly preferably from about 90 to about 98% of the distance between the waist hole 50 and each leg hole 52, and then the distance is measured in the direction parallel to the longitudinal axis 48. For the manufacture of connecting seams 88, covering basically the entire distance between the holes for the waist and legs 50 and 52, the fastening components 82-85 can be formed so that they cover from about 80 to 100 %, and more preferably from about 90 to about 98% of the distance between the end waist edge 70 and the end foot edge 72 of the side strips 34 and 134.

The absorbent base 32 and the fastening system 80 together form re-fastening briefs that have a waist opening 50 and two leg openings 52. When the fastening system is connected, it can be understood that the re-fastening fastening briefs include two elastomeric front side strips 34 extending from the waist opening to each leg opening, two elastomeric rear side strips 134 extending from the waist opening to each leg opening, two fasten removable fastening of the connecting seam 88 extending from the waist hole to each leg hole and located between the elastomeric front and rear bands, the elastomeric front waist band 54 located on the front waist part and located between the two elastomeric front side bands, the elastomeric back a waist band 56 located on the rear waist part and located between two elastomeric rear side strips, and two elastomeric foot parts 58, which are partially ok uzhayut each hole for the legs. Each elastomeric foot member 58 extends from a position adjacent to the elastomeric front side strip 34 in the front waist portion 22 to a position adjacent to the elastomeric rear side strip 134 in the rear waist portion 24.

Figure 4 shows alternative training pants 300, presented in a stretched and flat state. Training pants 300 include main bands 302 and 304, which are located in the front and rear waist portions 22 and 24, respectively. The main strip 302 in the front waist portion 22 forms the first and second side strips 310 and 312 that extend laterally outward from the composite structure 33 and the absorbent system 44 (FIG. 3). Similarly, the main strip 304 in the rear waist portion 24 forms the first and second side strips 314 and 316, which extend laterally outward from the composite structure 33 and the absorbent system 44.

Training pants 300 also include first and second fastening components 82 and 83 attached to the inner surface 28 of the rear connecting strips 314 and 316, and first and second mating fastening components 84 and 85 attached to the outer surface 30 of the front connecting strips 310 and 312. B one particular implementation of the fastening components 82 and 83 are fasteners with loops, and the mating fastening components 84 and 85 are fasteners with hooks, which to reduce the likelihood of irritating The skin is oriented outward, away from the body.

Both main strips 302 and 304 may be integral with the component of the composite structure 33, such as the body facing element 42, or the layer of the outer covering element 40, or be separate elements associated with the composite structure, or be a plurality of layers that are elements that make up a single whole, individual elements or their combinations. Alternatively, the main strips 302 and 304 may be portions of one single element, such as a component of the composite structure 33, for example, an elastic or tensile outer covering element (not shown). The main strips 302 and 304 and thus the side strips 310, 312, 314 and 316 may be elastic or inelastic materials. Turning to FIG. 5, in the presented embodiment, the main strips 302 and 304 are a plurality of elastomeric segments 320 located between the outer and inner facing each other layers 322 and 324.

The elastomeric segments 320 can be positioned and oriented so that the side strips 310, 312, 314 and 316 have elasticity in a direction substantially parallel to the transverse axis 49 of the training pants 300. The elastomeric segments 320 can be elastomeric films, materials, strands, fibers and etc. and include elastic materials similar to those described in connection with other components of the training pants 20 and 300. The layers 322 and 324 facing each other may include materials of the type described in connection with the body element 42, side strips 34, etc. P.

FIG. 6 is an enlarged view showing a plan view of a side strip 34 of the type shown in FIG. 1. 6 shows only one side strip 34, although it should be understood that other side stripes may have a similar design. The lateral strip 34 may be connected to the linear lateral edge 47 of the composite structure 33 along the line of attachment 66 and be located in the transverse direction behind this structure. The lateral strip 34 forms an outer edge 68 located at some distance from the attachment line 66, an end foot edge 70 located in the longitudinal direction closer to the center of the training pants 20, and an end waist edge 72 located in the longitudinal direction closer to the end of the training pants.

In specific implementations, the fastening component 85 is biased inwardly from the outer edge 68 and the end foot edges 70 and 72 to protect the user from irritation that may occur due to contact with the fastening component. More specifically, the fastening component 85 can be displaced in the transverse direction inward from the outer edge 68 in the area indicated by 100. In addition, the fastened component 85 can be displaced in the longitudinal direction inward from the end foot edge 70 in the area indicated by 102 and offset in the longitudinal direction inward from the end waist edge 72 in the area indicated by the number 104.

When setting the offset, it is taken into account that for a smaller offset, it is more difficult for children and parents to unfasten, but the product looks more like underpants, while for a larger offset it is easier for children and parents to unfasten, but the product has a hanging, sloppy look, not like underpants. Thus, it is preferred that the fastening component 85 is laterally displaced inward from the outer edge 68 by a distance of about 1 to about 15 mm, preferably about 1 to about 5 mm, for example about 2 mm. Preferably, the fastening component 85 is longitudinally displaced inward from the end foot edge 70 and from the end waist edge 72 by a distance of about 2 mm or more, preferably about 5 mm or more, for example from about 5 to about 15 mm.

7 shows one side strip 34 of an alternative implementation of a disposable absorbent article. The lateral strip 34 is connected to the composite structure 33 along the attachment line 66. The lateral strip 34 has an outer edge 68 offset laterally from the attachment line 66, and an end foot edge 70, and an end waist edge 72 that extends from the composite structure to the outer the edge. The side strip 34 shown in FIG. 7 includes a separate first part 90, a second part 92 and a third part 94, which are arranged in series from the connection line 66 to the outer edge 68. The fastening component 83 is located on the third part 94 adjacent to the outer edge 68 .

The first part 90 is connected to the second part 92 at the seam 96, and the second part is connected to the third part 94 at the seam 98. The shown seams 96 and 98 extend from the end foot edge 70 to the end waist edge 72 of the side strip 34. These seams can be permanent seams or seams that can be severed manually. Suitable permanent joints can be created by adhesive, ultrasonic or thermal bonding, or some combination thereof, and are intended to be detachable. Suitable seams that can be manually detachable can be created using tools such as an ultrasonic connection, so that the caregiver can easily detach the side strip 34 along the seam or along the seam. Preferably, such seams are false seams or butt welds. In specific implementations, the first and second parts 90 and 92 are elastomeric materials, and the third part 94 is a non-elastomeric material. Alternatively, the side strips may include two parts, one of which or both may be elastomeric and which are connected to each other by a separable seam or a permanent seam (not shown).

Other alternative training pants 400 are shown in a stretched and flat state in FIG. Training pants 400 include an absorbent base that has a longitudinal axis 48, a transverse axis 49, front and rear waist edges 38 and 39 parallel to the transverse axis, and opposing side edges 36 located between the front and rear waist edges. Training pants 400 have a front waist portion 22 adjacent to the front waist edge 38, a rear waist portion 24 adjacent to the rear waist edge 39, and gusset 26, which is located between the front and rear waist parts and connects these parts. The absorbent base shown in the drawing includes a rectangular composite structure 33 with two elastomeric front side strips 34 associated with the composition structure in the front waist portion 22 and two elastomeric rear side strips 134 associated with the composition structure in the rear waist portion 24. Preferably, the side strips 34 located in the front waist portion 22 were displaced in the longitudinal direction relative to the rear side strips 134 located in the rear waist portion 24.

Shown in the drawing, the training pants 400 also include two parts, the substrate 402, which go outward from the rear side strips 134 and associated with them.
