Description

Technical Field

[0001] This utility model relates to personal care hygiene products, and more particularly to disposable trouser-type absorbent products. Background Technology

[0002] Pant-style absorbent products, such as adult incontinence pants and baby diapers, are an important category of modern personal care and hygiene products, widely used in daily life and medical care. Absorbency, comfort, and fit are key attributes of these products and are also aspects that users pay close attention to. Typically, users are more interested in whether these products provide a good snug fit to prevent staining the wearer's clothes or sheets without sacrificing comfort.

[0003] Figure 1 A known shorts-type absorbent garment 10 is shown. As shown, in its flat state, the absorbent garment is roughly divided along the longitudinal direction L into a front waist section 20, a back waist section 30, and a crotch section 40 connecting the front waist section 20 and the back waist section 30. The absorbent core 80 is arranged in the crotch section 40, roughly corresponding to the longitudinal center line Y. This type of shorts-type absorbent garment 10 can be folded along the transverse fold line X, and the sides of the front waist section 20 and the back waist section 30 can be joined together to construct a... Figure 2 The wearing configuration is shown. In this configuration, the front waistband 20 and the back waistband 30 can enclose a waist opening 60 to accommodate the wearer's waist, while the crotch area 40 can enclose a leg opening 70 to accommodate the wearer's thighs. Conventional absorbent trousers 10 have elastic bands 50 along the side edges of the crotch area 40, forming a so-called leg band. The function of the elastic band is to provide tension to ensure that the leg opening 70 fits snugly against the user's thighs, thereby preventing leakage of bodily fluids.

[0004] However, this design has several obvious drawbacks. First, existing leg band designs often fail to fully cover the user's thighs, especially in the groin area or around the groin. This can lead to leakage of bodily fluids in these areas, affecting product usability and user comfort. Second, because some areas of the leg opening may lack elastic bands, or the elastic bands may be unevenly distributed, the tension of the leg elastic bands is inconsistent across the entire opening area. This inconsistency not only affects the product's leak-proof performance but may also cause discomfort during wear. Furthermore, in traditional designs, the distribution and tension control of the waistband elastic bands are often less than ideal, resulting in poor overall waistband stability. This not only affects the product's wearing stability but may also cause pressure or discomfort in the lower back during use.

[0005] Therefore, there is a need in this field to optimize the arrangement of elastic bands in absorbent products. Summary of the Invention

[0006] The present invention aims to provide a trouser-type absorbent product that can at least partially solve the defects of the prior art.

[0007] According to one aspect of the present invention, a trouser-type absorbent article is provided, having mutually perpendicular longitudinal and transverse directions, and divided along the longitudinal direction into a front waist area, a back waist area, and a crotch area connecting the front waist area and the back waist area, characterized in that the trouser-type absorbent article further includes two sets of elastic elements extending obliquely relative to the longitudinal direction, each of the two sets of elastic elements crossing the crotch area and extending into the front waist area and the back waist area, wherein in the front waist area and the back waist area, the two sets of elastic elements are opposite to each other in the transverse direction.

[0008] This solution improves the arrangement of the elastic elements forming the leg cuffs, extending them from the front waistband across the crotch area into the back waistband. By optimizing the distribution and tension of the elastic elements, the leg cuffs ensure more comprehensive coverage of the user's thighs, especially in key areas prone to leakage, such as the groin and inner thighs. The improved leg coverage also ensures consistent tension of the elastic elements at the front and back waistbands throughout the entire range, thereby enhancing the product's leak-proof performance and user comfort. The extended elastic elements into the front and back waistbands also improve the overall integrity and stability of the waistband, ensuring a better fit and reducing discomfort during wear.

[0009] In some embodiments, the two sets of elastic elements intersect in the crotch area near the front waist area.

[0010] In some embodiments, the trouser-style absorbent article is configured to fold into a wearing configuration, wherein in the wearing configuration, the front waist area and the back waist area together form a waist opening, the crotch area forms a leg opening, and the two sets of elastic elements intersect between the fold line and the front waist area.

[0011] In some embodiments, each set of elastic elements extends obliquely and continuously between the front waist area and the rear waist area.

[0012] In some embodiments, one end of each set of elastic elements extends to the edge of the front waist area.

[0013] In some embodiments, the edge of the front waist region includes a laterally extending front waist edge and two front waist side edges connected to the laterally opposite ends of the front waist edge, the two sets of elastic elements extending to the two front waist side edges and close to the front waist edge, respectively.

[0014] In some embodiments, the other end of each set of elastic elements extends to the edge of the lower back area.

[0015] In some embodiments, the edge of the lower back area includes a laterally extending lower back edge and two laterally opposite lower back side edges connected to the laterally opposite ends of the lower back edge, the two sets of elastic elements extending to the two lower back side edges and away from the lower back edge, respectively.

[0016] In some embodiments, each group of elastic elements comprises 2 to 300 elastic elements having an average spacing of 1 to 50 millimeters, an average fineness of 50 to 1000 deniers, and an average pre-strain of more than 150%.

[0017] In some embodiments, the trouser-type absorbent article includes a liquid-permeable top sheet facing the wearer, a liquid-impermeable back sheet facing the clothing, and an absorbent core sandwiched between the top sheet and the back sheet, the absorbent core being disposed in the crotch area, and the two sets of elastic elements crossing at positions corresponding to the absorbent core.

Unless otherwise specified, the directional terms used in this specification are generally in accordance with the conventional directions understood by those skilled in the art.

[0028] The terms “first,” “first,” “second,” “second,” and similar terms used in this invention do not indicate any order, quantity, or importance, but are used to distinguish one component from others.

[0029] Terminology Definition

[0030] Regarding absorbent articles, “disposable” means absorbent articles that are not typically intended to be washed or otherwise restored or reused as absorbent articles (i.e., they are intended to be discarded after a single use and are preferably recyclable, compostable, or in other words, disposed of in an environmentally compatible manner).

[0031] "Absorbent articles" or "absorbent clothing" herein refers to articles that can be placed close to or near the wearer's body (i.e., adjacent to the body) to absorb and contain various liquid, solid, and semi-solid excretions from the body. Such absorbent articles as described herein are intended to be discarded after their limited lifespan, rather than washed or otherwise restored for reuse. It should be understood that this disclosure applies to a variety of disposable absorbent articles, including but not limited to diapers, training pants, swim trunks, incontinence products, absorbent feminine hygiene products, etc., without departing from the scope of this disclosure.

[0032] As used herein, the term "nonwoven" or "non-woven fabric" generally refers to a web with a layered structure of individual fibers or yarns, but not in a manner identifiable as a knitted fabric. Examples of suitable nonwoven or nonwoven fabrics or webs include, but are not limited to, meltblown webs, spunbond webs, bonded-carded webs, air-jet webs, co-formed webs, and hydroentangled webs.

[0033] As used herein, the term "meltblown fiber web" generally refers to a nonwoven web prepared by means of a method in which molten thermoplastic material is extruded as molten fibers through numerous, typically circular, fine die capillary pores into a stream of aggregated high-speed gas (e.g., air), thereby thinning the fibers of the molten thermoplastic material to reduce their diameter. Subsequently, the meltblown fibers are transported by a high-speed gas flow and placed on a collecting surface to form a web of randomly distributed meltblown fibers. Generally, the meltblown fibers can be continuous or discontinuous microfibers, typically less than 10 micrometers in diameter, and are usually viscous when placed on a collecting surface.

[0034] As used herein, the term "spunbond web" generally refers to a web comprising substantially continuous fibers of small diameter. These fibers are produced by extruding molten thermoplastic material through numerous, typically circular, small spinneret capillary openings, followed by a rapid reduction in the diameter of the extruded fibers by, for example, lead-out drawing and / or other known spunbonding mechanisms. "Proximal" and "distal" refer to the relative proximity or distance of an element from the longitudinal or lateral centerline of the structure, respectively (e.g., relative to the same longitudinal axis, the proximal edge of a longitudinally extending element is closer to the longitudinal axis than the distal edge of the same element).

[0035] "Facing the body" and "facing the clothing" refer to the relative positions of components or the relative positions of the surfaces of a component or group of components, respectively. "Facing the body" means that during wear, a component or surface is closer to the wearer than some other components or surfaces. "Facing the clothing" means that during wear, a component or surface is further away from the wearer than some other components or surfaces (i.e., the component or surface is closer to the wearer's clothing, which may be worn over a disposable absorbent material).

[0036] As used herein, the terms "stretchable" or "extensible" generally refer to the dimensional stretchability of a material in the direction of stress, such that the dimension in the direction of stress can be extended by at least about 25%, or at least about 50%, or at least about 75% compared to its natural relaxed state. Stretchable materials do not necessarily have restorative properties or need to have significant restorative properties. For example, elastic materials are stretchable materials with restorative properties. Meltblown fiber webs can be stretchable, but their restorative properties are significantly reduced compared to their extensibility, or even non-restorative, and therefore they are stretchable but inelastic materials.

[0037] As used herein, the terms "elastomer" or "elastic" generally refer to a material that, by applying a tensile force, is stretched in at least one direction (such as the machine direction), and by releasing the tensile force, shrinks / recovers to approximately its original size. For example, a stretched material may have an extended length of at least about 50% longer than its unstretched length in its relaxed state, and by releasing the tensile force, it may recover to a length within at least 50% of its extended length.

[0038] As used herein, the term "elastic element" includes elongated materials that are elastic, such as, but not limited to, elastic rubber bands, elastic filaments, elastic bands, elastic fiber nonwoven sheets, etc. Elastic rubber bands, for example, can be made from spandex using a spinning process on a warp beam.

[0039] As used herein, the term "bonded" refers to the joining, adhesion, connection, attachment, etc., of two elements. Two elements are considered to be bonded together when they are joined, adhered, connected, attached, etc., directly or indirectly to each other, such as when bonded to an intermediate element. Bonding can be achieved, for example, by adhesives, pressure bonding, thermal bonding, ultrasonic bonding, splicing, stitching, and / or welding.

[0040] As used herein, the term "ultrasonic welding" refers to a method, for example, by passing material through a slit between an ultrasonic generator and a support roller.

[0041] Pants-style absorbent products

[0042] This utility model relates to a pant-style absorbent article, particularly a disposable pant-style absorbent article. This pant-style absorbent article improves the layout of the elastic elements to provide complete leg coverage, ensures consistent tension of the leg cuffs at the front and back waistbands, and improves the overall integrity of the waistband. The technical solution of this utility model can provide the wearer with improved leak-proof performance and better comfort.

[0043] Figure 3 and Figure 4 An exemplary illustration is shown of the pant-type absorbent article 100 of this utility model. It should be understood that, without departing from the scope of this disclosure, the technical solution of this utility model is suitable for personal wear absorbent articles for care, including but not limited to diapers, training pants, pull-up pants, and feminine hygiene products.

[0044] like Figure 3 As shown, the trouser-type absorbent article 100 is presented in a flat configuration and in a naturally relaxed state, without elastic deformation or wrinkling under external force. The trouser-type absorbent article 100 has mutually perpendicular transverse T and longitudinal L directions, as well as a thickness direction perpendicular to the TL plane (not shown in the figure). For clarity, it is also shown in... Figure 3The longitudinal center line Y is marked. Along the longitudinal direction L, the trouser-type absorbent product 100 can be divided into the front waist area 200, the crotch area 400 and the back waist area 300, wherein the crotch area 400 connects the front waist area 200 and the back waist area 300.

[0045] The trouser-style absorbent garment 100 is designed to be worn around the wearer's lower torso. (Reference) Figure 4 The illustrated wearing configuration, in this state, has a front waistband 200 that substantially covers the wearer's abdominal waist, a back waistband 300 that substantially covers the wearer's back waist, and a crotch area 400 positioned between the wearer's legs. The front waistband 200 has two opposing front waistband edges 220 on either side laterally, and a front waistband edge 210 extending laterally between the two front waistband edges 220. The back waistband 300 has two opposing back waistband edges 320 on either side laterally, and a back waistband edge 310 extending laterally between the two back waistband edges 320. The crotch area 400 has crotch area edges 410 on opposite sides laterally. The front waistband edges 210 and the back waistband edges 310 substantially define the two ends of the trouser-type absorbent garment 100 in the longitudinal direction L.

[0046] The single-piece absorbent garment 100 needs to be folded in the crotch area 400 so that the front waist area 200 and the back waist area 300 can be joined together near the front waist side edge 220 and the back waist side edge 320 to form a wearable shorts configuration. Figure 3 The approximate lateral fold line X is shown. At this point, the front waist edge 210 and the back waist edge 310 together enclose a waist opening 600 to accommodate the wearer's torso, while the two crotch side edges 410 of the crotch area 400 each enclose a leg opening 700 to accommodate the wearer's thighs. To ensure a snug fit at the waist and prevent the trouser-type absorbent garment 100 from slipping off, front waist elastic members 230 can be arranged along the front waist area 200 near the front waist edge 210, extending laterally from one front waist side edge 220 to the other. Similarly, a back waist elastic member 330 extending between the two back waist side edges 320 can be arranged in the back waist area 300 near the back waist edge 310. The front waist elastic member 230 and the back waist elastic member 330 can be selectively arranged on the trouser-type absorbent garment 100, or they can be arranged together on the trouser-type absorbent garment 100.

[0047] In addition to the waist-hugging fit, this invention also provides an elastic element 500 for completely wrapping the legs to ensure good conformity of the leg opening 600 and provide uniform tension. Figure 3 and Figure 4As shown, two sets of elastic elements 500 are arranged in an X-shape on the trouser-type absorbent article 100. Each set of elastic elements 500 extends obliquely from the front waist area 200 into the back waist area 300 relative to the longitudinal direction L, and the orientation of the two sets of elastic elements 500 is opposite, such that the two sets of elastic elements 500 pass through each other approximately in the crotch area 400 and form a cross. At the intersection of the two sets of elastic elements 500, the two sets of elastic elements 500 can be fixedly joined together by any suitable means, such as bonding, heat fusion, etc. Alternatively, the two sets of elastic elements 500 may simply pass through each other without being fixedly joined at the intersection, in which case the two sets of elastic elements 500 are stacked vertically at the intersection and there may be a certain gap.

[0048] The elastic element 500 can extend continuously between the front waist zone 200 and the back waist zone 300. In the wearing configuration, such an elastic element 500 forms a complete wrap around the wearer's legs, especially near the groin, thus providing uniform tension along the circumference of the wearer's thighs and avoiding uneven tension and side leakage caused by missing elastic elements in certain areas. Furthermore, the elastic element 500 extending across the crotch zone 400 into the front waist zone 200 and the back waist zone 300 also improves the integrity of the waistline.

[0049] Two sets of elastic elements 500 can cross in the crotch area 400 near the front waist area 200. In the wearing configuration, this part of the crotch area 400 may be exposed to a larger amount of bodily fluid impact than other parts, and the crossing elastic elements 500 here can provide stable support and a good fit, preventing product deformation and also helping to distribute the absorbed fluid evenly. Advantageously, the two sets of elastic elements 500 cross between the lateral fold line X and the front waist edge 210.

[0050] The two sets of elastic elements 500 are positioned far apart from each other from their intersection point to the front waist area 200, and each set of elastic elements 500 can extend to a front waist side edge 220 at its end in the front waist area 200, so that the ends of the two sets of elastic elements 500 are laterally opposite each other in the front waist area 200. The front waist side edge 220 extends between the front waist edge 210 and the crotch side edge 410, and the end of each set of elastic elements 500 can be closer to the front waist edge 210, or at least one elastic element in each set of elastic elements 500 can extend to the junction of the front waist edge 210 and the front waist side edge 220. When in the wearing configuration, in addition to providing complete coverage of the legs, the two sets of elastic elements 500 also apply tension near the front waist area 200 to make the pant-style absorbent garment 100 fit the wearer's waist and abdomen better, which is not possible with conventional pant-style absorbent garments. The tension applied by the elastic element 500 near the front waistband 200 is mainly concentrated on both sides of the wearer's abdomen, avoiding the center of the abdomen, such as the lower abdomen or navel, to prevent pressure on the central abdomen, which is unpleasant for wearers during special periods (such as menstruation). Due to the presence of the elastic element 500, the number of strands in the front waistband elastic element 230 can also be appropriately reduced, thereby reducing the wearer's feeling of tightness while maintaining a stable fit with the absorbent fabric 100.

[0051] The X-shaped intersection causes the segments of the two sets of elastic elements 500 from the intersection point to the lower back area 300 to be spaced far apart from each other. Each set of elastic elements 500 can extend from its end in the lower back area 300 to a side edge 320 of the lower back area 300, making the ends of the two sets of elastic elements 500 laterally opposite each other. The side edge 320 of the lower back extends between the lower back edge 310 and the crotch side edge 410. The end of each set of elastic elements 500 in the lower back area 300 can be far from the lower back edge 310, or closer to the crotch side edge 410; for example, the elastic element 500 can extend roughly along the crotch side edge 410 to the side edge 320 of the lower back. In this wearing configuration, each set of elastic elements 500 does not need to form a roughly closed configuration to completely cover the wearer's thigh.

[0052] To effectively absorb the wearer's bodily waste, the trouser-type absorbent article 100 has an absorbent core 800 arranged in the crotch area 400. Here, the absorbent core 800 can extend into the front waist area 200 at one end and into the back waist area 300 at the other end. The absorbent core 800 can be a composite material made of laminated liquid-absorbent raw materials, exhibiting a degree of stretchability and comfort, being non-irritating to the wearer's skin, and capable of absorbing and retaining bodily waste. The absorbent core 800 can be made of any suitable material and can contain any number of desired layers. For example, in one embodiment, the layers of the absorbent core 800 can include an outermost top layer and a bottom layer, with a core support layer and an absorbent material layer disposed therebetween. The top and bottom layers can be made of the same material, or they can be configured to have different absorption properties. For example, the top and bottom layers can both be made of liquid-permeable nonwoven sheets. The core support layer can be made of, for example, hot-air nonwoven sheets and can be a single-layer or multi-layer laminated structure. The absorbent layer can be made of any suitable absorbent material, such as the superabsorbent polymer (SAP). SAP refers to a polymer that absorbs and retains a very large amount of liquid relative to its own mass. Crosslinkable absorbent polymers classified as hydrogels absorb aqueous solutions through hydrogen bonds and other polar forces with water molecules. The absorbency of SAP is partly based on its ionicity (an index of the ion concentration in the aqueous solution) and the hydrophilic polar functional groups of SAP. SAP is generally manufactured by polymerizing acrylic acid mixed with sodium hydroxide in the presence of an initiator to form sodium polyacrylate (sometimes called sodium polyacrylate). Other materials can also be used to manufacture superabsorbent polymers, such as polyacrylamide copolymers, ethylene maleic anhydride copolymers, crosslinked carboxymethyl cellulose, polyvinyl alcohol copolymers, and starch-grafted copolymers of crosslinked polyethylene oxide and polyacrylonitrile. SAP can be present in absorbent articles in particulate or fibrous form. In one embodiment, the aforementioned two sets of X-shaped elastic elements 500 can cross each other at a position near the front waist region 200 of the absorbent core 800.

[0053] Although not shown in the figure, it can be understood that the trouser-type absorbent article 100 includes a top sheet and a back sheet that are opposite each other along the thickness direction. The absorbent core 800 is arranged between the top sheet and the back sheet.

[0054] The topsheet can be a single-layer or multi-layer laminate that defines a surface in direct contact with the wearer's skin and is liquid-permeable to receive bodily excretions and guide them toward the absorbent core 800. Preferably, the topsheet retains almost no liquid in its structure, thus providing a relatively comfortable and non-irritating feel while in close contact with the wearer's skin. In various embodiments, the topsheet can be a single-layer or multi-layer composite structure, and the multi-layer composite structure itself can include similar or different materials. The topsheet can be constructed from various nonwoven webs such as meltblown webs, spunbond webs, hydroentangled webs, or air-permeable bonded carded webs. Examples of suitable surface materials include, but are not limited to, natural fiber webs (such as cotton), rayon, hydroentangled webs, polyester, polypropylene, polyethylene, nylon or other thermally bondable fibers (such as bicomponent fibers), polyolefins, copolymers of polypropylene and polyethylene, linear low-density polyethylene, and bonded carded webs of aliphatic esters (such as polylactic acid). Perforated membrane and web materials, as well as laminates or combinations thereof, can also be used. Particularly advantageous is that the top sheet is constructed as a three-dimensional surface layer with a three-dimensional texture, for example, by using a three-dimensional composite material comprising alternating protrusions and recesses. Two sets of elastic elements 500 can be sandwiched between two layers of nonwoven fabric of the top sheet and positioned by an adhesive. The adhesive can be applied continuously along the extension direction of the elastic elements or it can be applied intermittently. Each set of elastic elements 500 can include multiple strands of elastic elements, for example, between 2 and 300 strands. These elastic elements can have an average spacing of 1 mm to 50 mm and an average fineness of 50 to 1000 denier, and can also have an average pre-strain of more than 150%. These elastic elements have been stretched to a certain stretch ratio when laminated between the two layers of nonwoven fabric of the top sheet. For example, the stretch ratio of the elastic elements can be designed to be more than 120%, preferably 120% to 300%.

[0055] The backsheet is typically liquid-impermeable and is the part of the trouser absorbent article 100 facing the wearer's clothing. The backsheet can be configured to allow gas to escape from the trouser absorbent article 100 but prevent liquid from flowing through. Any liquid-impermeable material can generally be used to form the backsheet. The liquid-impermeable backsheet can consist of a single layer or multiple layers, and these single or multiple layers can themselves comprise similar or different materials. Suitable materials that can be used include microporous polymer membranes, polyolefin membranes such as polyethylene or polypropylene, nonwoven fabrics and nonwoven laminates, and membrane / nonwoven laminates. The specific structure and composition of the backsheet layer can be selected from a variety of known membranes and / or fabrics, and specific materials are appropriately selected to provide desired levels of liquid barrier, strength, abrasion resistance, tactile properties, aesthetics, etc.

[0056] Through comparative experiments conducted by the inventors, it was found that the trouser-type absorbent product 100 with two sets of elastic elements with X-shaped crosses can significantly improve the fit and leak-proof performance of the leg opening. It conforms to the physiological curves of the wearer's front waist, especially the abdomen, buttocks and back waist, and improves the overall integrity of the waist area while providing uniform tension along the circumference of the thigh.

[0057] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0058] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes, modifications, and combinations made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
