Description

ABSORBENT ARTICLE HAVING CONTAINER SKIRTS WITH RECEIVING DEPOSITS Background of the Invention Technical Field The present invention relates to an absorbent article for receiving exudates from the body. Such absorbent articles may have containment skirts to prevent or contain the spreading or flow of exudates from the body.

Description of Related Art Absorbent articles such as infant diapers, training underpants, adult incontinence products, and the like are well known. Such articles have achieved wide acceptance due to the ability to receive and absorb exudates from the body. In order to move the bowel movements and other exudates out of the user's body, the prior art has considered using an opening in the center of the absorbent article.

For example, U.S. Patent No. 4,892,536 issued to DesMarais et al., Describes a diaper with a large duct in the center section of the liner side to body to facilitate movement of solid and semi-solid waste materials towards outside the user's body. It was assumed that this arrangement reduces the contact of the waste with the user's skin.

Freeland, in the United States patent of North America No. 4,990,147 and Freeland et al., In United States Patent No. 5,269,775 and other patents describe similar attempts to prevent solid waste materials from contacting a diaper wearer.

The patents listed above are all intended to place the solid waste in direct contact with the absorbent core through a relatively large opening located centrally in the liner from side to body. Therefore, the solid waste occupies a deposit, located centrally in the absorbent article, between the body-side liner and the absorbent core. There is no teaching to modify any of the flaps or containment barriers to provide a path or direction for the exudates to move transversely across the length or width of the absorbent article to a receiver reservoir on or to the side of the exterior perimeter of the absorbent article. absorbent article. In addition, the location of the opening shown in the patents mentioned above does not easily collect an overflow of urine. The sudden presence of a large amount of urine was not examined by these patents.

Synthesis of the Invention In order to improve the protection of runoff from a diaper, the present invention modifies one or more of the containment barriers or skirts of an absorbent article by providing openings or conduits, preferably near the base of the barriers leading to a reservoir receiver, on or to one side of the outer perimeter of the absorbent article. The receiver receives urine, fecal material, or other exudates which travel through the openings, for example, when pressure builds up from a pond against the skirt or run. The openings in the containment barriers thus prevent the exudates from flowing on or around the containment barriers by providing an alternative path to release the pressure against the containment barriers.

In one aspect, the present invention resides in an absorbent article having a front portion, a back portion and a crotch portion connecting the front and rear portions, the crotch portion having the opposite longitudinal side portions. The absorbent article includes a base structure, the base structure comprising, in combination, a liquid-permeable body-side liner and an outer cover. An absorbent core is located between the body side liner and the outer shell. A containment barrier is attached to the side-to-body liner and includes at least one conduit formed through the containment barrier. A reservoir wall is attached to the barrier and the base structure to form a reservoir for the exudates.

Another embodiment of the invention resides in an absorbent article having a front part, a back part, and a crotch portion connecting the front and back portions, the crotch portion having the opposite longitudinal side portions. The absorbent article includes a base structure, the base structure comprising, in combination, a liquid-permeable body-side liner and an outer cover. An absorbent core is located between the body side liner and the outer shell. The first and second longitudinally extending leg cuffs are located in the crotch portion in the longitudinal side portions oppositely positioned thereon. The absorbent article also includes a pair of containment barriers containing at least one conduit and extending longitudinally from the front to the rear of the article. The barriers are attached to the lining from side to body. The first and second reservoir walls are joined to a respective one of the containment barriers in the corresponding first places. A second location of each reservoir wall is attached to the base structure in a position disposed away from the respective containment barrier and into the outer edge of the side-to-body liner.

In another embodiment, the wall of the reservoir may be attached to the outer cover facing away from the barriers.

In another embodiment, the reservoir wall may be attached at the upper distal end of the containment barrier and at the lower base of the containment barrier.

This arrangement forms the reservoir with the containment barrier and the reservoir wall only.

The ducts may comprise slits, openings of various shapes, as well as breaks of the seams joining the respective containment barriers to the liner from side to body. The openings preferably have an open area of no more than about 7 square centimeters for each barrier, and preferably have cross-sectional areas corresponding to diameters of from 5 to 25 millimeters. At least one duct, and preferably at least three ducts are contemplated for each containment barrier.

In addition, the ducts can be formed by cuts in the containment barriers, the cuts are serpentine in their configuration and form serpentine edges, and are formed prior to attachment to the liner from side to body. The serpentine edges provide lobes and open or cut spaces between the respective lobes. The containment fins are not attached to the liner in these spaces when the distal ends of the lobes are attached or otherwise attached to the liner from side to body in intermittent locations. These spaces then comprise the conduits mentioned above.

In addition, the conduits can be formed by cuts in the containment barriers, the cuts being of a zig-zag configuration and forming zig-zag edges, and being formed prior to attachment to the liner from side to body. The zig-zag edges provide teeth and open or cut spaces between the respective teeth. The containment fins are not attached to the liner in these spaces when the distal ends of the teeth are attached or otherwise attached to the liner from side to body. These spaces then comprise the conduits that have been mentioned above.

Detailed Description of the Preferred Modality The present invention relates to absorbent articles designed to absorb exudates from the body. Although the preferred embodiments of the present invention will be described in terms of a disposable diaper adapted for use by infants and children crawling around the lower torso, the present invention is equally applicable to other absorbent articles such as incontinent briefs. adults, learning underpants and the like.

The present invention can also be better understood by reference to the drawings in which like numbers represent like elements. Figure 1 illustrates a diaper 8 suitable for use in the present invention. The diaper 8 of Figure 1 shows the containment barriers 10, the ducts 12, the side-to-body liner 14, and the wall of the reservoir 16. Figure 1 also shows the attachment means, such as the hook and loop fasteners. curl 18 and 20, to secure the diaper on the child. The first fastener 18 comprises a mechanical fastener, such as the hook of a hook and loop fastening system mounted on the outer cover 22. The second fastener 20 then comprises a corresponding curl material attached to the outer cover 22 and adapted to engage releasably with the hook material of the first fastener 18. Furthermore, other known fastening means for holding the diaper 8 on a person can be used. Also, as shown in Figure 1, the conduits 12 are preferably located on or on one side of the base 23 of the containment barriers 10.

The containment barriers 10 shown in Figures 1 and 2 include the elasticized material 24 for forming and placing the barrier. The barrier material may be somewhat permeable. The containment barriers 10 may be attached to the liner from side to body by heat sealing, sonic bonding, bonding with adhesive or the like. Adhesive bonding includes the use of adhesive lines, adhesive spots or other arrangements.

The containment barriers 10 may include the barrier elastics 24 as shown in Figure 2. These barrier elastics may suitably comprise one or more individual strands of elastomeric material. For example, a plurality of elastomeric yarns may be configured in a generally parallel and spatially separated array. The elastic threads can be distributed over the full width of the barrier and formed of a rubber material. The elastic threads may also be placed in an intermediate position or fold of the containment barrier 10 in the longitudinal direction. The elastic threads may run by the full extent of the containment barrier 10 or only by a portion of the length of the containment barrier near the crotch of the diaper 8. A suitable elastic thread may, for example, be composed of an elastomer LYCRA® of 470 decitex, a 620 decitex LYCRA® elastomer or other elastomers with suitable characteristics. The barrier elastics 24 are preferably integrated into the containment barriers 10 at least on one side of the distant edge 26 of the respective containment barrier 10 and separated from the side facing to the body 14 in a stretched condition so that the contraction of the elastic components thereof fold and shorten the distant edge 26 of the containment barrier 10 of the fully extended condition. As a result of this, the distant edge 26 of the containment barrier 10 tends to place itself in an outwardly spaced relation from the side facing to the body 14 towards a generally vertical and approximately perpendicular configuration in especially the crotch portion of the body. diaper as shown in figures 2, 5 and 6.

The leg cuffs 28 are suitably formed by parts of the outer cover 22 and / or the side-to-body liner 14, which extend transversely beyond the longitudinal sides of the absorbent core 30. The leg cuffs 28 may also be formed of separate materials which are attached to the outer cover 22 and / or to the side facing to the body 14. The leg cuffs 28 include the leg elastics 22. Suitable materials for forming the leg elastics 32 include the yarns or tapes of a polymeric, elastomeric material which adhere to the diaper 8 in the leg cuff 28 while in a stretched position, or which are attached to the diaper 8 while the diaper is folded, so that the elastic constrictive forces are the leg cuff 28. In addition, the leg elastics 32 shown in Figures 2 and 5 can be made of a material similar or identical to the elastics of barrier 24.

The containment barriers 10 can be constructed of a material which is the same as the material comprising the side-to-body liner 14. Alternatively, the containment barriers 10 can also be made of a material which is the same as the material of the material. the outer cover 22. The containment barriers 10 are preferably liquid impervious. The containment barrier 10 may be formed of a polymeric film material or of a non-woven material, for example, which is essentially impermeable to liquid. The containment barriers 10 can be formed by a single or multiple layer of material with appropriate elastics secured thereto as shown in Figure 5. Figures 2, 5 and 6 show the presence of the elastics 24 in the containment barrier. Other arrangements are also contemplated. For example, the elastics can be placed in multiple locations of the containment barrier 10.

The proper body side liner 14 can be manufactured from a wide selection of fabric materials such as porous foams, cross-linked foams, perforated plastic films or natural fibers. For example, the side-to-body liner 14 may comprise wood or cotton fibers. Other possible materials are synthetic fibers, such as polyester or polypropylene fibers, or a combination of natural and synthetic fibers. The body side liner 14 is suitably used to help insulate liquids maintained in the absorbent core 30 of the wearer's skin.

Various woven and non-woven fabrics can be used for the side-to-body liner 14. For example, the body-side liner 14 can be composed of a meltblown or bonded fabric of polyolefin fibers. The body side liner may also comprise a carded and / or bonded fabric composed of natural and / or synthetic fibers. The body side liner may also be composed of an essentially hydrophobic material wherein the hydrophobic material is treated with a surfactant or otherwise processed to impart a desired level of wettability and hydrophilicity. In a particular embodiment of the present invention, the body side liner 14 may comprise a polypropylene fabric bonded with non-woven yarn composed of fibers of about 2.8-3.2 deniers formed into a fabric having a basis weight of about 22 grams per square meter and a density of about 0.06 grams per cubic centimeter. The fabric is then treated with about 0.28 percent by weight of a surfactant. The body side liner 14 may comprise a multiplicity of components or layers which correspond to any of the materials described herein, as well as others known in the art.

It is generally preferred that the outer cover 22 of the diaper 8 is formed of a material which is essentially impermeable to liquids. A typical outer cover 22 can be made of a thin plastic film or other material impermeable to the flexible liquid. For example, the outer cover 22 can be formed of a polyethylene film having a thickness of from about 0.012 millimeters to about 0.051 millimeters. If the outer cover 22 is to have a fabric-like feel, it may comprise a polyethylene film laminated to a surface of the non-woven fabric, such as a fabric bonded with polyolefin fiber spinning. For example, a polyethylene film having a thickness of about 0.015 millimeters can have thermally laminated thereto a fabric bonded with polyolefin fiber yarn having a thickness of from 1.5 to 2.5 denier per filament, whose non-woven fabric has a weight base of around 24 grams per square meter. In addition, the outer cover 22 may be formed of a woven or nonwoven fibrous fabric which has been constructed or treated in whole or in part to impart a desired level of liquid impermeability to the selected regions that are adjacent to or close to the absorbent core. Furthermore, the outer cover 22 can finally be composed of a microporous material which allows the vapors to escape the absorbent core 30 while preventing the liquid exudates from passing through the outer cover 22. The outer cover 22 and the liner side to body 14, in combination, form a base structure 33 for diaper 8.

The absorbent core 30 suitably comprises a matrix of hydrophilic fibers, such as a cellulose fluff, in combination with a high-absorbency material commonly known as superabsorbent material. In a particular embodiment, the absorbent core 30 comprises a mixture of superabsorbent hydrogel forming particles and wood pulp fluff. Instead of the wood pulp fluff, one can use synthetic, polymeric or meltblown fibers or a combination of melt blown fibers and natural fibers. The superabsorbent material can be mixed essentially homogeneously with the hydrophilic fibers or it can be combined in another way in the absorbent core.

Alternatively, the absorbent core 30 may comprise a laminate of fibrous fabrics and superabsorbent material or other suitable means for maintaining a superabsorbent material in the localized area.

The absorbent core 30 can have any of a number of shapes. For example, the absorbent core may be rectangular, I-shaped or T-shaped. It is generally preferred that the absorbent core 30 be narrower in the crotch portion than in the front or back portion.

The high-absorbency material in the absorbent core 30 can be selected from polymers and natural, synthetic and modified natural materials. The high-absorbency materials can be inorganic materials, such as silica gels or organic compounds, such as degraded polymers. The term degradation is preferred to any means for effectively rendering the materials normally water-soluble essentially water soluble but swellable. Such means may include, for example, physical entanglement, crystalline domains, covalent bonds, complexes and ionic associations, hydrophilic associations such as hydrogen bonding and hydrophobic associations or Van der Waals forces.

The upper edges (see Figures 2 and 5) of the reservoir walls 16 are preferably attached to the containment barriers 10 at or near the distal edges 26 of the containment barriers 10 and outward from the side-to-body liner 14. The walls of the tank can be formed of materials similar to those contained in the outer cover 22. The walls of the tank 16 are preferably formed of an impermeable nonwoven material or film, and / or a combination of these two. Examples of the materials for the walls of the tank 16 include a polyethylene film having a thickness of about 0.012 millimeters or a polyethylene film thermally laminated to a cloth bonded with spinning polyolefin fibers. The walls of the reservoir 16 are also preferably attached to the base structure 33 outwardly of the containment flap 10 and towards the outside edge of the diaper 8 as shown in Figures 2 and 5. This arrangement forms a reservoir 34 receiving the exudates.

In a first clamping location, a first surface of a reservoir wall 16, near an upper edge 35 thereof is attached or clamped to a corresponding surface of the respective containment barrier 10 near the distal edge 26. The lower edge 36 of the tank wall 16 is attached to the base structure 33 and / or of the containment barrier 10 near the base 23. For example, a surface near a lower edge 36 of the tank wall 16 is attached to the corresponding surface of the base structure 33. Therefore, the wall of the tank 16 is attached to the containment barrier 10 and the base structure 33 to thereby form the tank 34.

This arrangement allows urine and / or fecal matter and the like to travel through conduit 12, including in response to pressure against retaining barrier 10. Exudates are then received by reservoir 34, formed between the wall of the reservoir 16, the containment flap 10, and optionally the base structure 33. In general, the exudates pass through the conduit 12 to the reservoir 34 in preference to runoff beyond or above the containment barriers 10. The The reservoir wall 16 can be joined to the containment barrier 10 and the base structure 33 by stitching, heat sealing, sonic bonding, adhesive bonding or the like.

The conduits 12 of a containment barrier 10 are sufficiently large so that an almost liquid bowel movement and / or urine can pass through, but is small enough to prevent entrapment of the body parts. The conduits 12 may comprise slits, openings of various shapes, as well as interruptions in the junction between the containment barrier and the side-to-body liner. The openings in the ducts 12 can have a total combined open area of from 0.1 to 7 square centimeters for each containment barrier 10. Preferably, each opening has an open area corresponding to a cross-sectional area of a diameter of from about 5 to around 25 millimeters. Preferably, each individual opening is not larger than 0.5 square centimeters to avoid any possibility of a strangulation. The slits can have a length of from about 5 to about 25 millimeters. Preferably, the slits are less than 12 millimeters, long, to avoid any possibility of a strangulation. In most cases, all openings combined, have a total open area for both containment barriers 10 of no more than 12 square centimeters. The conduits 12 can be spaced intermittently by the full length of the containment barrier 10 as shown in Figure 1 or they can be confined to a target area. One such area will be along the back of the barrier to collect exudates from bowel movements. A preferred area for the conduits 12 is along the base or bottom 23 of the containment barrier 10 near the side-to-body liner 14 as shown in Figure 1.

Although any number of conduits may be effective with respect to the applicant's invention, preferably at least three conduits are present in each containment barrier 10.

The conduits 12 can be formed by cutting a single piece of material into two containment barriers 10 in a zigzag manner as shown in Figures 3 and 3a. After the cut is completed, the two containment barriers with the zig-zag edges are created from a piece of material as shown in Figure 3a. Then, the distal portions 38 of the teeth 40 formed by the zig-zag edges of each containment barrier 10 are sewn, attached or otherwise secured in a longitudinal manner on the side liner to the body 14 in intermittent places . When the containment barriers 10 are joined, the open spaces 42 between the teeth 40 are left unattached or unclamped. This arrangement forms the conduits 12 from the spaces 42 between the teeth 40 of the containment barriers 10 and there is no waste of any piece of material when the conduits 12 are formed.

In addition, a serpentine pattern can be cut from a sheet of material as shown in Figures 4 and 4a. This sheet of material, when cut into two pieces, then becomes two containment fins with two serpentine edges. Distant portions 44 of the lobes or extensions 46 formed by the serpentine edges of each containment barrier 10 are then sewn, attached or otherwise fastened, preferably longitudinally on the side-to-body liner 14 in intermittent places. When the containment barriers 10 are joined, the open spaces 48 between the lobes 46 are left unattached. This arrangement forms the ducts 12 of the spaces 48 between the lobes 46 of the containment barriers 10. The second barrier 10 created by the edges of the serpentine cut is held in a similar manner. Again, the spaces 48 between the lobes 46 of the serpentine pattern then comprise conduits 12 which allow the exudates to travel to the reservoir 34. The formation of the barriers 10 in this manner ensures that there is no waste of any piece of material when ducts 12 are formed.

Even though the zig-zag pattern and any serpentine patterns have been illustrated, there is an infinite variety of other patterns that can also be used. The main criterion for selecting a pattern is to provide the proper number of ducts 12 and the dimensions for these.

The volume of the reception tank 34 is controlled, at least in part, by the place where the upper edge 35 of the wall of the tank 16 is joined to the containment barrier 10 and the place where the lower edge 36 of the wall of the tank 16 is attached to a surface of the base structure 33 or to the base 23 of the containment flap 10. The attachment of the bottom edge 36 to the wall of the tank 16 to the outer cover 22 on a surface of the The base structure 33 as shown in Figure 5 contributes to an increased volume for the reservoir 34. In the illustrated embodiments, the longitudinal ends of the containment fins 10 are also attached or otherwise attached to the base structure 33. Similarly, the longitudinal ends of the reservoirs 34 are closed by securing the wall of the reservoir 16 to the containment barrier 10 along a line through from generally the lower edge 36 to the b. upper order 35. This arrangement forms a reservoir 34 connected through conduits 12 to central portion 50 of diaper 8 which may contain a sudden flow of exudates which could otherwise leak around or over the containment barriers 10 Furthermore, as shown in Figure 5, spacing the wall of the reservoir 16 outwardly from or beyond the leg elastics 32 maximizes the volume capacity of the reservoir 34. This arrangement also allows the exudates contained in the reservoir 34 passing through the liner sideways to the body 14 to reach the absorbent core 30. This allows more exudates to reach the absorbent core 30. In such cases where the exudates first travel to the reservoir 34 and thus to the core 30 , the reservoir 34 acts as a temporary retention site, retaining the exudates away from the user's body until the liquid parts thereof are absorbed by a core 30. This increases the efficiency and capacity of the diaper 8 to operate effectively during a Sudden release of exudates without runoff.

The spacing between the containment fins , through the central portion 20 of the diaper 8 can be varied according to a variety of acceptable design parameters. As the containment barriers 10 are closely spaced together to minimize the area of stain on the buttocks due to bowel movement, the volume available between the barriers 10, in the absence of the invention, to contain the exudates are reduced. In the absence of the invention, when filling the exudates the bag in the central part 50 of the diaper, the exudates begin to go over the barrier and / or the back of the diaper. Therefore, the invention shown here reduces the stain area and provides greater comfort to the user because an alternate path of low resistance is provided for the movement of exudates through the conduits 12 and out of the skin of the wearer. With regard to urine, the same logic can be applied. A sudden flow of urine can be released more quickly than the core 30 can absorb. Excess urine can pass through line 12 to reservoir 34 and hold until it is absorbed by the absorbent core 30. Once in the reservoir 34, the urine can flow back out of the conduit 12 to the absorbent core 30 or it can flow through the liner from side to body 14 directly to the absorbent core 30. This arrangement also allows a more efficient and faster absorption by the core 30 since the urine is contacting a larger surface area of the core. The invention can also be arranged so that a portion of the reservoir is directly above the absorbent core 30. Such an arrangement requires that the containment barriers 10 be placed closer to each other than what is shown in the drawings.

Another embodiment of the invention is illustrated in Figure 6. In this embodiment, the wall of the reservoir 16 is attached only to the containment barrier 10. This arrangement can be more simply constructed than the previous incorporations. A first surface of the upper edge 35 of the reservoir wall 16 is sewn, joined or otherwise secured near the distal edge 26 of the containment barrier 10. The opposite surface of the lower edge 36 of the reservoir wall 16 is held near the base 23 of the containment barrier 10. Even when the opposite surface of the tank wall 16 is shown attached to the base of the barrier in Figure 6, either the same or the opposite surface of the tank wall 16 can provide the joint forming the reservoir 34. The locations at the ends of the reservoir wall 16 are attached to the containment barrier 10 to form a sealed reservoir 34 except for the conduits 12.

Those skilled in the art will now see that certain modifications can be made to the apparatus and methods described herein with respect to the illustrated embodiments, without departing from the spirit of the present invention. And even though the invention has been described above with respect to the preferred embodiments, it will be understood that the invention is adapted in numerous rearrangements, modifications and alterations and all such arrangements, modifications and alterations are intended to be within the scope of the appended claims.

An absorbent article as claimed in clause 17, characterized in that said first and second containment barriers comprise sections of a material cut by a zig-zag cut forming the corresponding zig-zag edges along a length of the same, said zig-zag edges form teeth in said material, and the corresponding spaces between said teeth, the spaces between said teeth comprise said at least one conduit in each respective containment barrier when said teeth of each containment barrier are attached to the lining side to the body.

22. An absorbent article as claimed in clause 17, characterized in that it includes at least three conduits through each containment barrier.

23. An absorbent article as claimed in clause 17, characterized in that said at least one conduit of each containment barrier is formed by slits in the respective barriers.

24. An absorbent article as claimed in clause 17, characterized in that said containment barriers are attached to said liner from side to body in intermittent places, separated by spaces between adjacent ones of the intermittent places, when said conduits comprise the respective spaces . SUMMARY An absorbent article includes an absorbent core located between a side-to-body liner and an outer cover. A containment barrier is attached to the liner from side to body. A reservoir wall is secured to the containment barrier and to a base structure comprising, in combination, the side-to-body liner and an outer cover. The conduits in the containment barriers allow the exudates to flow from the region between the barriers and to a defined reservoir outside the containment barrier. In one embodiment, a surface near the outer edge of the tank wall joins the liner from side to body. In another embodiment, the reservoir wall is attached to the outer cover of the absorbent article. In yet another embodiment, the reservoir wall is attached to the containment barrier, first near a distant edge thereof, and secondly near the base of the containment barrier.
