Description

[Technical Field]

[0001] The present invention provides a reusable article for retaining body fluids and solids. The present invention also provides a reusable garment comprising the reusable article. [Background technology]

[0002] The listing or discussion of an apparently prior-published document in this specification should not necessarily be taken as an acknowledgement that the document is part of the state of the art or is general general knowledge in the art.

[0003] Conventional reusable articles for retaining body fluids and solids, such as diaper liners, sanitary napkins, and panty liners, typically comprise an absorbent core layer, such as a terry toweling layer, and a leak-proof outer cover formed from a heavy polymer film. These are typically used as absorbent members in underwear-like garments, such as diapers (e.g., training pants, pull-on pant diapers, refastenable diapers, and pant diapers), incontinence briefs, or feminine hygiene undergarments. Increasing the liquid absorbency of such articles often requires increasing the size of the absorbent region or adding (overlapping) additional absorbent core units, potentially resulting in bulky articles that can be uncomfortable for the wearer. Reusable articles with limited liquid absorption capacity may leak body fluids and moisture onto the user's skin, exposing the user's skin to body fluids and moisture, potentially causing discomfort or skin irritation.

[0004] Thus, there remains a need for alternative and / or improved reusable articles for retaining body fluids and solids. Summary of the Invention

[0005] The present invention provides a reusable article for retaining body fluids and solids, said reusable article comprising: a liquid-impermeable inner layer having a first surface and a second surface, the first surface configured to face the skin of a user in use; and Liquid impermeable outer layer Equipped with the liquid-impermeable outer layer and the liquid-impermeable inner layer are attached to one another at their peripheral edges, thereby forming a liquid-retaining chamber between the second surface of the liquid-impermeable inner layer and the liquid-impermeable outer layer; The liquid-impermeable inner layer includes a plurality of holes that allow liquid to pass through the liquid-impermeable inner layer and into the liquid-retention chamber.

[0006] The present invention also provides reusable garments comprising the reusable articles of the present invention. In some examples disclosed herein, the reusable garments are reusable diapers, such as training pants, pull-on pant diapers, refastenable diapers, or pant diapers.

[0007] The inventors have found that the reusable article of the present invention can collect and retain bodily fluids excreted by a user away from the user's skin. Specifically, the bodily fluids are collected and retained in a liquid retention chamber of the reusable article, thereby reducing exposure of the user's skin to the bodily fluids, thereby increasing the user's comfort after the article is soiled and / or reducing any skin irritation that may be caused by prolonged contact of the user's skin with the bodily fluids. In some examples disclosed herein, the reusable article further comprises a liquid-impermeable covering layer extending over a portion or substantially the entire first surface of the liquid-impermeable inner layer. The liquid-impermeable covering layer includes a plurality of recesses. The inventors have found that the recesses in the liquid-impermeable covering layer can function as a receptacle for solid exudates excreted by the user, thereby reducing the user's skin exposure to the solid exudates and, therefore, further increasing the user's comfort after the reusable article is soiled and / or reducing any skin irritation that may be caused by the solid exudates. The recesses can also facilitate the passage of bodily fluids into the fluid-retention chamber away from the user's skin.

[0008] Preferred but optional features are set forth in the dependent claims. Further aspects and embodiments of the reusable articles and reusable garments of the present invention will become apparent from the following description, drawings, and claims. As can be understood from the foregoing and following description, each and every feature described herein, and each and every combination of two or more such features, is included within the scope of the present disclosure, provided that the features included in such combinations are not mutually inconsistent. Furthermore, any feature or combination of features may be specifically excluded from any embodiment. [Brief explanation of the drawings]

[0010] As previously mentioned, the present invention provides a reusable article for retaining bodily fluids and solids.

[0011] In embodiments herein, the term "comprising" may be interpreted as requiring the recited features, but not limiting the presence of other features. Alternatively, the term "comprising" may relate to a situation where only the recited components / features are intended to be present (e.g., the term "comprising" may be replaced with the phrases "consists of" or "consists essentially of"). It is expressly contemplated that both broader and narrower interpretations may apply to all aspects and embodiments of the present invention. In other words, the term "comprising" and its equivalents may be replaced with the words "consisting of" or "consisting essentially of" and their equivalents, and vice versa.

[0012] As used herein, the term "reusable article" refers to a device configured to retain bodily fluids and solids, e.g., a device placed against or in proximity to a wearer's body to collect and retain various bodily exudates (e.g., urine and feces). Reusable articles are configured to be reused for one or more use cycles to collect and retain bodily fluids and solids. Exemplary reusable articles for storing and retaining bodily fluids and solids include diaper liners, sanitary napkins, panty liners, and the like. Reusable articles may be used, for example, as liquid retention components in garments such as diapers (e.g., training pants, pull-on pant diapers, refastenable diapers, pant diapers), incontinence briefs, or underwear-like garments such as feminine hygiene underwear.

[0013] The reusable article of the present invention comprises a liquid-impermeable inner layer and a liquid-impermeable outer layer. The liquid-impermeable inner layer comprises a first surface and a second surface, the first surface being configured to face the skin of a user when the reusable article is in use. The liquid-impermeable outer layer and the liquid-impermeable inner layer are attached (or adhered) to each other at their peripheries so that a liquid-retention chamber is formed between the second surface of the liquid-impermeable inner layer and the liquid-impermeable outer layer. For example, the liquid-impermeable outer layer and the second surface of the liquid-impermeable inner layer may be attached to each other at their peripheries to form a liquid-retention chamber. Typically, the liquid-impermeable outer layer and the liquid-impermeable inner layer are attached to each other along their entire peripheries. Optionally, the liquid-impermeable inner layer and / or the liquid-impermeable outer layer comprise a flange portion extending outward from the attachment point between the two layers. The flange portion may also be configured to fold inward toward the first surface of the liquid-impermeable inner layer and may optionally be elasticated. For example, the flange portion may be formed of or include elastic thread. The flange portion can help form a barrier around the periphery of the reusable article to help direct liquid through holes in the liquid-impermeable inner layer.

[0014] Preferably, the liquid-impermeable inner layer and the liquid-impermeable outer layer are attached to each other so that the liquid retained in the liquid-retention chamber does not leak from the liquid-retention chamber at the attachment point between the two layers. Typically, the liquid-impermeable inner layer and the liquid-impermeable outer layer are attached to each other by stitching, adhesive (e.g., adhesive tape, liquid adhesive, or hot-melt powder adhesive), and / or ultrasonic bonding. When the adhesive is adhesive tape, the adhesive tape may be single-sided or double-sided, and the tape may have a single layer or multiple layers, each of which may have one or more functions, such as a barrier layer or an elastic layer. When the adhesive is liquid adhesive, the adhesive may be hot-melt adhesive, liquid resin, or a combination thereof (e.g., the adhesive may be hot-melt adhesive / liquid resin bonding by nozzle extrusion or liquid resin bonding by screen printing / template printing). In some examples, the adhesive or ultrasonic bonding may be thermally stable up to at least 190°C, allowing the reusable article to be washed and dried multiple times. Unless otherwise specified, as used herein, the term "thermal stability" is intended to define no change in the physical state of the component after exposure to the recited temperature for a period consistent with a machine drying cycle.

[0015] The liquid-impermeable inner layer includes a plurality of holes configured to allow liquid to pass through the liquid-impermeable inner layer and enter the liquid-retention chamber. Thus, when the reusable article is being used, bodily fluids, such as urine or menstrual fluid, discharged from the user may pass through the liquid-impermeable inner layer and enter the liquid-retention chamber, where the bodily fluids may be retained until removed from the reusable article.

[0016] The holes may be of any size suitable for allowing liquid to pass through them in the absence of external pressure. For example, the holes may have a diameter of about 0.5 cm to about 3 cm, e.g., about 0.5 cm, about 1 cm, about 1.5 cm, about 2 cm, about 2.5 cm, or about 3 cm. The specific size of the holes is not particularly important, as long as they allow liquid to pass through the liquid-impermeable inner layer without external pressure.

[0017] For the avoidance of doubt, the term "about" as used herein may allow for a degree of variation in a value or range, for example, within 10%, within 5%, within 1%, within 0.5%, within 0.1%, within 0.05%, within 0.01%, within 0.005%, or within 0.001% of the stated limits of the stated value or range, and includes the exact stated value or range.

[0018] The liquid-impermeable inner layer and the liquid-impermeable outer layer may each be formed from any suitable material that is impermeable to liquids, particularly liquid water. The liquid-impermeable inner layer and the liquid-impermeable outer layer may be formed from the same type of material or different types of materials. Typically, the material is hydrophobic. The layer material, when in gaseous form, allows water to escape. Examples of suitable materials include hydrophobic polymer materials, durable water repellent (DWR) treatments for any fabric, hydrophobic treatments or films applied to any fabric, silicone coatings for any fabric, polyurethane coatings for any fabric, hydrophobic spray treatments for any fabric, or knit / woven liquid-impermeable structures using hydrophobic yarns.

[0019] Optionally, the liquid-impermeable outer layer may include one or more seams (or stitches) extending across a portion or the entire length of the liquid-impermeable outer layer. For example, the one or more seams may extend across the liquid-impermeable outer layer from a first edge of the liquid-impermeable outer layer to a second edge of the liquid-impermeable outer layer. Typically, there may be two or more (e.g., 2, 3, 4, 5, 6, or more) seams, each extending across the liquid-impermeable outer layer. The one or more seams may be any type of seam suitable for reducing stretching of the liquid-impermeable outer layer when the liquid-retention chamber contains a user's bodily fluids. The one or more seams may be one or more straight seams and / or zigzag seams extending across the liquid-impermeable outer layer.

[0020] In some examples, a first surface of the liquid-impermeable inner layer may be formed from an outer hydrophobic material and a second surface of the liquid-impermeable inner layer may be formed from an inner hydrophobic material, which may be formed from the same or different types of materials, both of which are impermeable to liquids, particularly liquid water.

[0021] The liquid retention chamber of the reusable article may contain a wicking layer, which is positioned adjacent to the multiple holes in the liquid-impermeable inner layer. The wicking layer has a first surface and a second surface. The first surface of the wicking layer faces the second surface of the liquid-impermeable inner layer, and the second surface of the wicking layer faces the liquid retention chamber. Typically, the first surface of the wicking layer is attached to the second surface of the liquid-impermeable inner layer and covers the multiple holes. The wicking layer functions to wick liquid through the holes in the liquid-impermeable inner layer and direct it into the liquid retention chamber. The wicking layer also functions as a barrier against solid exudates, filtering bodily fluids from the solid exudates and retaining the solids on the first surface of the wicking layer. Bodily fluids pass through the liquid-impermeable inner layer and the wicking layer to enter the liquid retention chamber, thereby reducing exposure of the user's skin to bodily fluids. This can increase the comfort of the user after the reusable article has become soiled and / or reduce any skin irritation that may be caused by prolonged contact of the user's skin with bodily fluids. By only allowing bodily fluids to pass through to the liquid-retention chamber, the reusable article may be easier to clean after being soiled by a user.

[0022] For the avoidance of doubt, the term "attached" as used herein refers to elements that are connected or joined together by sewing, bonding, fastening, adhering, etc. Many methods for attaching elements together are known in the art and include, for example, adhesive bonding (e.g., laminating), pressure bonding, heat bonding, ultrasonic bonding, mechanical fastening, etc. The means for attaching the elements is preferably heat stable up to at least 190°C, thereby allowing the reusable article to be washed and dried multiple times.

[0023] In some examples, the wicking layer and the liquid-impermeable inner layer may be laminated together. For example, the two layers may be laminated together with a laminating adhesive between the wicking layer and the second surface of the liquid-impermeable inner layer. Suitable laminating adhesives include, but are not limited to, polyamide adhesives, polyester adhesives, polyurethane adhesives, and mixtures of two or more thereof. Laminating the two layers together can simplify the assembly process of the reusable article of the present invention.

[0024] The wicking layer may be formed from any material suitable for wicking (or transporting or wicking) fluid through one or more holes in the liquid-impermeable inner layer. Typically, the wicking layer may be formed from fibers or yarns made from fibers, the fibers and yarns being selected from one or more of the group consisting of polyamides, polyesters, polyolefins, polyurethanes, polyacrylonitriles, natural cellulose, regenerated cellulose, regenerated cellulose derivatives (i.e., cellulose acetate and cellulose triacetate), natural proteins, and regenerated proteins. The wicking layer may be manufactured using techniques such as knitting (warp knitting, such as Russell tricot; weft knitting, such as circular knitting and flat knitting), weaving, nonwoven processes (blowing, staple nonwoven, spunlaid, airlaid, needlepunch, thermal bond, hydroentanglement, chemical bond, etc.), electrospinning, force spinning, etc. Additionally, the wicking layer may include one or more coatings, treatments, encapsulations, or encasements that enhance liquid and moisture management functions such as wicking rate, wicking capacity, diffusion and distribution rate, unidirectional liquid transport, and the like.

[0025] As one example, the wicking layer may comprise a 51% cotton material, and one or both surfaces of the wicking layer (i.e., the first and second surfaces) may be treated with a hydrophilic composition or material (e.g., polyethylene oxide, polyvinyl alcohol, polyacrylamide, polyacrylic acid, polyvinylpyrrolidone, hydrophilic silicone, or hydrophilic polyurethane) and / or a hydrophobic composition or material (e.g., silicone, polyfluoroalkyl acrylate, polyacrylate, polyurethane, or wax) to form a net hydrophilic gradient across the wicking layer.

[0026] The wicking layer may be configured to allow fluid to seep through the multiple holes in the liquid-impermeable inner layer toward the liquid-retention chamber. For example, the first surface of the wicking layer facing the second surface of the liquid-impermeable inner layer may be more hydrophilic (i.e., less hydrophobic) than the second surface of the wicking layer facing the liquid-retention chamber. For example, the first surface may be treated with a hydrophilic material and / or the second surface may be treated with a hydrophobic material. This may result in a combination of a "pulling" force generated by the hydrophilic properties of the surface facing the liquid-impermeable inner layer and a "pushing" force generated by the hydrophobic properties of the second surface facing the liquid-retention chamber. This arrangement may allow moisture or liquid to seep through the wicking layer and into the second surface of the liquid-impermeable inner layer. The hydrophilic and hydrophobic compositions may be applied to the wicking layer using conventional methods known to those skilled in the art.

[0027] The liquid-retention chamber of the reusable article may further contain a liquid-absorbent material, typically disposed between the second surface of the wicking layer and the liquid-impermeable layer.

[0028] Additionally or alternatively, the liquid retention chamber of the reusable article may further accommodate a liquid collection container. Typically, the liquid collection container is disposed between the second surface of the wicking layer and the liquid-impermeable outer layer. The liquid collection container may be attached to the second surface of the wicking layer, for example, by bonding (such as adhesive bonding or ultrasonic bonding) or stitching. The surface of the liquid collection container adjacent to the wicking layer is configured to allow one-way fluid inflow into the liquid retention chamber. For example, the liquid collection container may include one or more liquid non-return valves. Typically, the one or more liquid non-return valves may be formed from a polymer material such as silicone. The one or more liquid non-return valves may be disposed adjacent to the second surface of the wicking layer so that, as liquid passes through the holes in the liquid-impermeable inner layer and through the wicking layer, the liquid enters the liquid collection container, where it is retained until removed by the user. The liquid collection container may include an outlet valve, such as a faucet, that a user can open to remove liquid retained in the liquid collection container. The walls of the liquid collection container may be formed from any suitable material that is impermeable to liquids, particularly liquid water, including those described above for the liquid-impermeable inner and outer layers.

[0029] The liquid-impermeable outer layer may include an opening that allows access to the liquid-retention chamber. For example, the surface of the liquid-impermeable outer layer may include an opening that allows access to the liquid-retention chamber, which opening is reversibly sealed, for example, by a reversible and waterproof seal (e.g., a waterproof zipper fastener or a waterproof hook-and-loop fastener). Such an opening allows access to the liquid-retention chamber to remove bodily fluids retained therein, after which the chamber can be sealed for further use. For example, the opening may allow removal of a soiled liquid-absorbent material for cleaning or replacement with a non-contaminated liquid-absorbent material. Alternatively, for example, the opening may allow removal of the liquid collection container and / or access to the outlet valve of the liquid collection container.

[0030] The liquid-absorbent material may be formed from any material suitable for absorbing and retaining liquid. Suitable liquid-absorbent materials are known in the art and include, for example, cotton, cotton blends, foams, synthetic materials, absorbent polymer foams, nanotechnology-based or manufactured materials, or any other moisture-absorbing material. The liquid-absorbent material may have a density of about 50 g / m 2 ~about 500g / m 2 , for example, about 180 g / m 2 ~about 300g / m 2 For example, the liquid absorbent material may be formed from an 80:20 polyester:nylon blend fabric with a microfiber double terry knit. Other suitable liquid absorbent materials include polypropylene or cellulosic fabrics and blends thereof including cotton, bamboo, etc.

[0031] In some instances, the liquid absorbent material may be 100% polyester double terry cloth. Such a material is approximately 90% air, allowing for greater liquid absorption capacity as the polyester fibers do not expand significantly and moisture fills the voids in the polyester toweling.

[0032] In some other examples, the liquid-absorbent material may be formed from a blend of fibers including two or more of superabsorbent polymers (SAPs), hydrogels, and polyesters, or at least a portion of the liquid-absorbent material may be treated with SAPs and / or hydrogels. In such examples, these materials may provide increased liquid absorption capacity while reducing the thickness and weight of the liquid-absorbent material.

[0033] In some instances, the liquid-absorbent material is formed from one or more of a hollow fiber material, a toweling material, a knitted material, a woven material, and a hydrogel.

[0034] The liquid-absorbent material may be formed from at least one layer of liquid-absorbent material. At least one layer of the liquid-absorbent material may be folded to form a void within the liquid-retention chamber. The folds may be systematic (e.g., zigzag folds or pipe folds), or the folds may be random (e.g., the liquid-absorbent material or unit may be "scrunched-up" within the chamber). The void allows the liquid-absorbent material or unit to expand its volume within the liquid-retention chamber as it absorbs liquid that passes through the holes and enters the liquid-retention chamber.

[0035] In some examples, the liquid-absorbent material may be a liquid-absorbent unit comprising a liquid-absorbent layer and a barrier layer. The liquid-absorbent layer may be formed from a material suitable for absorbing and retaining liquid, such as those materials described hereinabove as suitable for liquid-absorbent materials. The barrier layer may be formed from any suitable material that retains water in liquid form, such as those described hereinabove as suitable for liquid-impermeable inner and outer layers of reusable articles. The presence of a barrier layer in the liquid-absorbent unit can enhance the retention of liquid by the liquid-absorbent material.

[0036] The liquid-absorbent material or liquid-absorbent unit may include a water-sensitive mechanism, such as a water-sensitive indicator, treatment, or dye, that indicates when the liquid-absorbent material's liquid-absorption capacity has been reached. For example, the liquid-absorbent material or unit may include a portion or layer dyed with a suitable water-sensitive dye. Suitable water-sensitive dyes include those that change color upon contact with liquids, such as urine. For example, the liquid-absorbent material or liquid-absorbent unit may be treated and thus include a hydrochromic dye. Suitable hydrochromic dyes are known in the art and commercially available. The dye change (e.g., color change) may be detected by opening a releasable opening in the liquid-impermeable outer layer. Additionally, or alternatively, the liquid-impermeable outer layer may include a window configured to allow the water-sensitive dye to be viewed through the liquid-impermeable outer layer. The window may be sealed with a suitable transparent polymeric material, such as, but not limited to, a polycarbonate film, a polyethylene terephthalate film, a polyvinyl chloride film, or a polyethylene film. Additionally or alternatively, the liquid-retention chamber may include a fullness detector, such as a dye detector that detects a change in a dye (e.g., a color change) that indicates that the liquid-retention capacity of the liquid-absorbent material or unit has been reached. The dye detector may be configured to alert a user when the capacity of the liquid-absorbent material or unit has been reached.

[0037] Additionally or alternatively, the liquid-retention chamber may include a smart sensor for real-time monitoring of the contents of the liquid-retention chamber, for example, a smart sensor that detects when a maximum volume of bodily fluid in the liquid-retention chamber has been reached and alerts the user.

[0038] The reusable article may further comprise a liquid-impermeable covering layer (or overlayer) extending over a portion (e.g., a central portion or substantially central portion) or substantially the entire first surface of the liquid-impermeable inner layer. For example, the liquid-impermeable covering layer may extend over at least about 10%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, or at least about 80%, at least about 90%, at least about 99%, or about 100% of the first surface of the liquid-impermeable inner layer.

[0039] The liquid-impermeable cover layer includes a plurality of recesses, at least one of which exposes one or more of the holes in the liquid-impermeable inner layer. For example, one recess may expose one or more of the holes in the liquid-impermeable inner layer.

[0040] The liquid-impermeable covering layer may be an integral part of the liquid-impermeable inner layer. Thus, the liquid-impermeable covering layer may form part of the first surface of the liquid-impermeable inner layer, and the liquid-impermeable inner layer may comprise the liquid-impermeable covering layer. For example, the liquid-impermeable covering layer may be in the form of an embossed surface of the liquid-impermeable inner layer that defines a plurality of recesses in the first surface of the liquid-impermeable inner layer.

[0041] Alternatively, the liquid-impermeable covering layer may be a separate layer disposed on and attached to the first surface of the liquid-impermeable inner layer. When the liquid-impermeable covering layer is a separate layer, it has a first surface and a second surface, the first surface being configured to face the skin of a user in use, and the second surface being disposed on and attached to the first surface of the liquid-impermeable inner layer.

[0042] At least one of the recesses exposes one or more holes in the liquid-impermeable inner layer. Typically, one recess exposes one hole. In some embodiments, each recess in the liquid-impermeable cover layer exposes one or more holes in the liquid-impermeable inner layer. In other embodiments, one set of recesses exposes one or more holes in the liquid-impermeable inner layer, and another set of recesses includes a substantially liquid-impermeable base. For example, if the liquid-impermeable cover layer is a separate layer, one set of recesses may expose one or more holes in the liquid-impermeable inner layer, and another set of recesses may expose only a portion of the first surface of the liquid-impermeable inner layer.

[0043] The recesses may have a well-like structure, a trough-like structure, a valley-like structure, or a vent-like structure. Typically, the recesses are well-like structures that are substantially conical, step-pyramid-like, cubical, cylindrical, circular-based frusto-conical, or rectangular-based frusto-conical.

[0044] The recesses in the liquid-impermeable inner layer may all have the same shape or may have different shapes, for example, the recesses may each independently have a shape selected from substantially conical, step-pyramidal, cubical, cylindrical, circular-based frusto-conical, or rectangular-based frusto-conical.

[0045] The recess may be shaped such that the diameter of the recess increases outward from the liquid-impermeable inner layer, such that the widest portion of the recess is positioned adjacent to the user's skin when the reusable article is in use. When the recess is positioned in this manner, it can function as a funnel to direct the user's bodily fluids into the holes in the liquid-impermeable inner layer and into the liquid-retention chamber.

[0046] The recesses in the liquid-impermeable coating layer may act as a receptacle for solid exudates, such as feces, excreted by a user. Retaining the solid exudates within the recesses can reduce exposure of the user's skin to the solid exudates, thereby increasing user comfort after the reusable article becomes soiled and / or reducing potential skin irritation caused by the solid exudates.

[0047] The liquid-impermeable covering layer may be composed of hydrophobic foam (e.g., polyurethane foam), structures formed from polyurethane, polyethylene, polystyrene, and rubber-based structures, and silicone structures (e.g., silicone gel, silicone puff, silicone extruded structure, etc.). The liquid-impermeable covering layer may be formed by injection molding using a suitable liquid-impermeable polymer, such as a suitable thermoplastic or thermosetting polymer. Alternatively, the liquid-impermeable covering layer may be a fabric designed with recesses, such as a fabric having a double jersey construction with tuck stitches or miss stitches to form the recesses. Such materials can be made using techniques and equipment known in the art, such as double / jacquard knitting machines. Optionally, the liquid-impermeable covering layer may include a hydrophobic finish / treatment on the outer surface of the liquid-impermeable covering layer and / or on the surface within the recesses. The presence of a hydrophobic finish / treatment fabric on the outer surface of the liquid-impermeable covering layer and / or within the recesses facilitates the removal of liquid or solid exudates retained in the recesses or otherwise disposed on the surface of the liquid-impermeable covering layer.

[0048] The reusable article may be a component of a reusable garment, such as a diaper, training pants, pull-on pant diaper, refastenable diaper, pant diaper, or incontinence brief, or underwear. For example, the reusable article may be a diaper liner, an incontinence brief liner, a sanitary napkin, or a panty liner. In such examples, the reusable article may be attached to a garment. The reusable article may be attached to a garment after the garment is manufactured, e.g., worn by a user. Or, for example, the reusable article may be incorporated into a garment during the manufacture of the garment, forming an integral part of such garment. That is, the reusable articles described herein may form part of a garment, whether integral or attachable / detachable.

[0049] Accordingly, the present invention further provides a reusable garment comprising the reusable article of the present invention. The reusable garment may comprise a main fabric body configured to be worn by a user, and a reusable article of the present invention attached to the inner surface of the fabric body and extending over at least the area affected by bodily exudate. One or more reusable articles of the present invention may be worn in any garment intended to come into contact with the user's skin. Typically, the reusable garment is a diaper (e.g., training pants, pull-on pant diapers, refastenable diapers, pant diapers), incontinence briefs, or feminine hygiene undergarments. The level of coverage of the interior surface area of ​​the reusable article in the reusable garment can be readily determined by one skilled in the art based on the intended use and the wearer's desired comfort level.

[0050] Reusable garments may include components that seal the garment to the user's body during use. This may be achieved using any conventional means, such as elastic, the use of silicone (including flocked silicone) to form a seal, or ruching. For example, the garment may include nanogrip elastic portions in the leg-opening areas of the reusable garment. Nanogrip elastic is a type of elastic that grips against the skin to provide a barrier effect. For example, it can be used to create a stand-up barrier around the leg openings to reduce leakage from the reusable garment. Nanogrip elastic can provide a better fit and avoid loose openings around the legs.

[0051] In examples where the reusable garment is a diaper (e.g., training pants, pull-on pant diapers, refastenable diapers, pant diapers), incontinence briefs, or feminine hygiene undergarments, the garment typically has the form of an underpant. The garment may include a fabric body having a waist opening and a pair of leg openings therebetween defining a crotch region that covers some or all of the user's genital area. The garment has an inner surface that contacts the user's skin during use. The garment also has an outer surface, some or all of which does not directly contact the user's skin during use. The garment comprises a reusable article of the present invention attached to the inner surface of the fabric body of the garment. The reusable article may be attached to the garment using stitching, or may be attached using adhesive, pressure-sensitive tape, or other forms of attachment.

[0052] In some examples, the reusable article is reversibly attached to the garment using reversible attachment means such as, but not limited to, buttons and buttonholes, zip fasteners, press studs and sockets, hooks and eyes, hook-and-loop fasteners (e.g., Velcro®), etc. Reversible attachment is particularly useful when the reusable article is attached to the garment by the user (e.g., when the reusable article is a diaper liner, incontinence brief liner, sanitary napkin, panty liner, or the like that is attached to the garment by the user).

[0053] In some examples, the reusable garment is a diaper, such as training pants, pull-on pant diapers, refastenable diapers, or pant diapers. Typically, when the garment is a diaper, it is a diaper for an infant. In examples where the garment is a diaper, the diaper can have a substantially hourglass configuration when open. It can include expandable leg openings and a waistband with reversible attachment means, such as buttons and buttonholes, zipper fasteners, press studs and sockets, hooks and eyes, and hook-and-loop fasteners (e.g., Velcro®), arranged to allow adjustment of the size of the waistband.

[0054] In some examples, reusable articles and reusable garments that include reusable articles can withstand multiple washing machine wash cycles and / or tumble dry cycles. For example, reusable articles and reusable garments that include reusable articles can withstand at least 30 (e.g., at least 50 or 100) washing machine wash and tumble dry cycles without changes in overall appearance, component integrity, and liquid management parameters, as discussed herein. For example, reusable articles and reusable garments can be reused for at least 30 (e.g., at least 50 or 100) washing and drying cycles. Material selection and unique construction ensure that reusable articles and reusable garments can be washed without compromising their functionality. Furthermore, the integrity of the reusable articles may be maintained for at least 30 (e.g., at least 50 or 100) washing and drying cycles. For example, the individual elements of the reusable articles specifically referred to herein are selected to remain chemically, thermally, and mechanically stable throughout the intended life of the product while being subjected to up to 30 (e.g., up to 50 or up to 100) washing and drying cycles.

[0055] Referring to the drawings, Figure 1 is a partially exploded cross-sectional view of an exemplary reusable article 100 of the present invention. The article has a liquid-impermeable inner layer 102 having a first surface and a second surface, with the first surface configured to face the skin of a user during use of the reusable article. The reusable article also has a liquid-impermeable outer layer 104 having an outer surface and an inner surface. The second surface of the liquid-impermeable inner layer 102 is disposed on the liquid-impermeable outer layer 104. The liquid-impermeable outer layer 104 and the liquid-impermeable inner layer 102 are attached to each other at their peripheries, thereby forming a liquid-retention chamber 106 between the second surface of the liquid-impermeable inner layer 102 and the inner surface of the liquid-impermeable outer layer 104. The liquid-impermeable inner layer 102 includes a plurality of holes 108 configured to allow liquid to pass through the liquid-impermeable inner layer and enter the liquid-retention chamber 106. The liquid-impermeable inner layer 102 and the liquid-impermeable outer layer 104 are attached to one another by stitching 105, although bonding (e.g., adhesive bonding or ultrasonic bonding) may also or instead be used. The liquid-impermeable inner layer 102 and the liquid-impermeable outer layer 104 have flange portions 102a, 104a extending outward from the attachment point between the two layers (i.e., from the point where the liquid-impermeable outer layer 104 and the liquid-impermeable inner layer 102 are attached to one another, e.g., by stitching). The flange portions provide a barrier around the periphery of the reusable article and help direct bodily fluids from the user through the holes 108 in the liquid-impermeable inner layer 102. The reusable article also has a wicking layer 110 positioned adjacent to the multiple holes 108 in the liquid-impermeable inner layer 102 such that each hole 108 exposes a portion of the wicking layer 110. Specifically, the wicking layer 110 is disposed between the second surface of the liquid impermeable inner layer 102 and the inner surface of the liquid impermeable outer layer 104, and is therefore disposed within the liquid-retention chamber 106. The wicking layer 110 and the second surface of the liquid impermeable inner layer 102 may be laminated together. The wicking layer 110 is formed from a material suitable for wicking fluid through the one or more holes 108 in the liquid impermeable inner layer 102.The wicking layer 110 has a first surface facing the second surface of the liquid-impermeable inner layer and a second surface facing the liquid-retention chamber 106. The liquid-retention chamber 106 may optionally contain a liquid-absorbent material 112 in the form of a layer of material suitable for absorbing and retaining liquid. When the liquid-absorbent material 112 reaches its liquid absorption capacity, it may occupy substantially all of the interior volume of the liquid-retention chamber 106. The liquid-absorbent material 112 may be arranged within the liquid-retention chamber 106 such that, when dry, it has one or more pleats that form voids within the liquid-retention chamber 106. The pleats may be organized pleats (e.g., zigzag pleats or pipe pleats), or the pleats may be disordered (e.g., the liquid-absorbent material may be "scrunched-up" within the chamber). The voids allow the liquid-absorbent material 112 to expand in volume within the liquid-retention chamber 106 as it absorbs liquid that passes through the holes 108 into the liquid-retention chamber 106. In use, bodily fluids from the user, such as urine, pass through the holes 108 into the liquid-retention chamber 106. The wicking layer 110 serves to wick the fluid through the holes 108 and direct it to the liquid-absorbent material 112 contained within the liquid-retention chamber 106, where it is retained until it is removed from the liquid-absorbent material 112 through the openings 114 in the liquid-impermeable inner layer 104.

[0056] 2 shows a partially exploded cross-sectional view of the exemplary reusable article 100 shown in FIG. 1 , further including a liquid-impermeable covering layer 220 extending over the first surface of the liquid-impermeable inner layer 102. The liquid-impermeable covering layer 220 is disposed over the first surface of the liquid-impermeable inner layer 102 and attached thereto, for example, by bonding (e.g., adhesive bonding or ultrasonic bonding). The liquid-impermeable covering layer 220 includes a plurality of recesses 222 in the form of well-like structures. Each of the recesses 222 exposes the hole 108 in the liquid-impermeable inner layer 102 and a portion of the wicking layer 110 attached to the second surface of the liquid-impermeable inner layer 102. Each of the recesses 222 may have a cylindrical shape. Other shapes are also possible; for example, the recesses may each have a conical shape, a step pyramid shape, a cube shape, a circular-based frustum shape, or a rectangular-based frustum shape. Each recess 222 may have a hydrophobic surface to facilitate removal of bodily fluids and / or solid matter disposed on the recess walls after the reusable article is soiled by a user. During use, bodily fluids from the user, such as urine, enter recess 222, which acts as a funnel to direct the fluid through hole 108 and into liquid-retention chamber 106. Recess 222 can function as a receptacle to retain solid matter, such as feces, excreted by the user.

[0057] 3 shows a partially exploded cross-sectional view of an exemplary reusable article 100 in which the liquid retention chamber 106 contains a liquid collection container 336 rather than a liquid-absorbent material. The liquid collection container 336 has a faucet-shaped outlet valve 338 that allows a user to remove liquid retained in the liquid collection container 336. The liquid collection container 336 has an upper surface that contacts the second surface of the wicking layer 110. The liquid collection container 336 and the wicking layer 110 are adhered to each other around their peripheries by a bond 340 (e.g., adhesive tape). The upper surface of the liquid collection container has a liquid check valve 342 that allows liquid to enter the liquid collection container 336 and be retained until the user removes the liquid via the outlet valve 338.

FIG. 10A shows the outer surface of the diaper, which faces away from the wearer during use, and FIG. 10B shows the inner surface of the diaper, which faces the user's skin during use. The outer surface shown in FIG. 10A is formed by a liquid-impermeable outer layer 704, while the inner surface of the diaper, shown in FIG. 10B, is formed by a liquid-impermeable inner layer 702 and a liquid-impermeable cover layer 720. The liquid-impermeable inner layer 702 has a hole 708. The liquid-impermeable cover layer 720 is disposed over a central portion of the liquid-impermeable inner layer 702, and recesses 722 in the liquid-impermeable cover layer 720 expose the hole 708 and a portion of the wicking layer 710, respectively. The liquid-impermeable outer layer 704 and the liquid-impermeable inner layer 702 are attached to one another around their entire periphery by stitching, thereby forming a liquid-retention chamber between the two layers. The liquid-impermeable outer layer 704 has an opening 714 that provides access to the liquid-retention chamber. The diaper has elastic leg cuffs 730 formed from flange portions extending outwardly from the liquid-impermeable outer layer 704 and the liquid-impermeable inner layer 702, elastic waistband regions 731, 732, and a fastening system 740.
