TECHNICAL FIELD

[0001] The present utility model relates to the field of disposable hygiene articles, in particular to a feminine absorbent article having satisfactory ease of use, donning adaptability and leakage protection. BACKGROUND

[0002] Feminine absorbent articles have been in widespread use for several decades. These pads are typically used during menstruation to capture menses and moisture. Generally, users of feminine absorbent articles want to feel clean and dry. Many improvements in feminine absorbent article technology have sought to improve one or both of these aspects. For example, feminine absorbent articles have been provided with flaps to reduce the likelihood of leakage and to help secure the feminine absorbent article to the wearer's undergarments. In addition, absorbent core materials have been introduced that can provide enhanced absorbent capacity in a relatively thin feminine absorbent article.

[0003] The feminine absorbent article in the prior art has a longitudinal axis L1 and a transverse axis T1, wherein there is a core absorbent area for rapid infiltration of menses near the intersection of the longitudinal axis L1 and the transverse axis T1. On both sides of the transverse direction T of the absorbent article, there are flaps with an extension length C1 in the longitudinal direction, wherein the flaps with length C1 are connected to the main body of the absorbent article in a blunt angle opening manner. The absorbent article in the prior art is prone to deformation when bonded to the crotch portion of the underpants. At this time, the flaps often do not smoothly fit the area of the crotch portion, but are curled or self-adhesive, and even the product cannot be used, which brings a very bad use experience to the consumer.

[0004] In view of the above, there is a need in the art to provide a feminine absorbent article having satisfactory ease of use, donning adaptability and leakage protection, which allows to improve the consumer's perception of the product during use, leakage protection and comfort. SUMMARY

[0032] Certain directional terms used herein, for example "inner", "outer", "upper", "lower" and other like terms, are used with respect to the orientation of the figures as normally viewed, and not with respect to any particular orientation in use. Unless specifically stated otherwise, the directional terms as used in the present specification are used in their normal sense.

[0033] The terms "first", "the first", "second", "the second", and similar terms as used herein do not denote any order, quantity, or importance, but are used to distinguish one element from another, and are used interchangeably with "one" and / or "the one".

[0034] Terminology

[0035] The term "disposable" or "throwaway" is used herein to describe absorbent articles that are not generally intended to be washed or otherwise restored for reuse or re-use as an absorbent article (e.g., they are intended to be discarded after a single use, and can also be configured to be recyclable, compostable, or disposed of in other environmentally compatible manners). Embodiments of the female absorbent articles described herein are disposable.

[0036] The term "feminine absorbent article" (also referred to as "sanitary napkin") refers herein to garments or other end-use personal care absorbent articles including, but not limited to, catamenial devices such as sanitary napkins, feminine pads, panty liners, incontinence devices, and the like.

[0037] With respect to structural terminology, the term "disposed" or "having" is used to mean that one or more elements are located at a particular place or position relative to other elements as a macro-structural whole or as individual elements joined to another element.

[0038] As used herein, the term "joined" includes configurations in which an element is directly secured to another element by affixing the element to the other element, and configurations in which the element is indirectly secured to the other element by affixing the element to an intermediate member that, in turn, is affixed to the other element.

[0039] As used herein, the terms "proximal" and "distal" refer to the relative position of an element closer to or further from, respectively, a longitudinal or lateral centerline of a structure (e.g., relative to the same longitudinal axis, a proximal edge of a longitudinally extending element is positioned closer to the longitudinal axis than a distal edge of the same element).

[0040] As used herein, the terms "body-facing" and "garment-facing" refer to the relative position of an element or the relative position of a surface of an element or group of elements. "Body-facing" means that the element or surface is closer to the wearer during wear than some other element or surface. "Garment-facing" means that the element or surface is further from the wearer during wear than some other element or surface (i.e., the element or surface is closer to the garment of the wearer, which can be worn over the disposable absorbent article).

[0041] As used herein, the term "machine direction (MD)" refers to the length of a feminine absorbent article in the direction in which it is manufactured, which can also be referred to herein as the longitudinal direction, as opposed to "cross-machine direction (CD)", which refers to the width of the feminine absorbent article in a direction generally perpendicular to the machine direction, which can also be referred to herein as the transverse direction.

[0042] As used herein, the term "meltblown web" refers herein to a nonwoven web formed by a process in which molten thermoplastic material is extruded through a plurality of fine, usually circular, die capillaries as molten fibers into converging high velocity gas (e.g., air) streams which attenuate the fibers of molten thermoplastic material to reduce their diameter, which can be microfiber diameter. Thereafter, the meltblown fibers are carried by the high velocity gas stream and are deposited on a collecting surface in a random dispersion arrangement to form a web of randomly dispersed meltblown fibers.

[0043] As used herein, the term "nonwoven fabric" or "nonwoven web" refers to a web having a structure consisting of interlayered but not individually identifiable fibers or threads as in a knitted fabric. Nonwoven fabrics or webs have been formed by a variety of processes, such as meltblown, spunbond, air-permeable bonded carded web (also known as BCW and TABCW), etc. The basis weight of nonwoven webs can typically vary, for example, from about 5, 10, or 20 gsm to about 120, 125, or 150 gsm.

[0044] As used herein, the term "spunbond web" refers to a web comprising substantially continuous fibers of small diameter. These fibers are formed by extruding molten thermoplastic material from capillaries of multiple fine, typically circular, spinnerets having the diameter of the extruded fibers, and then rapidly thinning it by, for example, drawing and / or other well-known spunbonding mechanisms.

[0045] As used herein, the terms “superabsorbent polymer,” “superabsorbent,” or “SAP” are to be used interchangeably and should refer to polymers that can absorb and retain a very large amount of liquid relative to their own mass. Superabsorbent polymers are classified as crosslinkable hydrogels that absorb aqueous solutions through hydrogen bonds and other polar forces with water molecules. The water-absorbing capacity of SAP is based in part on its degree of ionization (a coefficient of ion concentration in aqueous solutions) and the hydrophilic polar functional groups of SAP. SAP can exist in absorbent articles in particulate or fibrous form or as a coating on another material or fiber.

[0048] First see Figure 1 , Figure 1 This illustration shows a top view of an exemplary embodiment of the female absorbent article 100. Figure 1The feminine absorbent article 100 shown in FIG. 1 can have a longitudinal direction (L), a transverse direction (T), and a vertical direction (Z direction, i.e., a depth direction as described below). The feminine absorbent article 100 can have a longitudinal axis LI and a transverse axis Tl. The feminine absorbent article 100 can have a liquid permeable topsheet layer 101 facing the wearer and a liquid impermeable backsheet layer 102 facing the garment. An absorbent core 103 can be positioned between the topsheet layer 101 and the backsheet layer 102. The feminine absorbent article 100 can have a transverse direction upper edge 110A, a transverse direction lower edge 110B opposite the transverse direction upper edge 110A, and a pair of opposing longitudinal direction side edges 111A and 111B. In various embodiments, the feminine absorbent article 100 can take on various geometric shapes, but will generally have a pair of opposing transverse direction upper and lower edges 110A and 110B and a pair of opposing longitudinal direction side edges 111A and 111B.

[0049] The topsheet layer 101 and the backsheet layer 102 can each extend beyond the outermost peripheral edges of the absorbent core 103 and can be joined together completely or partially at the periphery using known joining techniques that form a sealed perimeter zone. For example, the topsheet layer 101 and the backsheet layer 102 can be joined together by adhesive bonding, ultrasonic bonding, or any other suitable bonding method known in the art.

[0050] The feminine absorbent article 100 can have a front portion 100A, a back portion 100C, and a middle portion 100B extending between the front portion 100A and the back portion 100C. Generally, the front portion 100A of the feminine absorbent article 100 is adapted to be worn toward the front of the wearer proximate the pubic region, the middle portion 100B is adapted to be worn proximate the crotch region of the wearer, and the back portion 100C is adapted to be worn toward the back of the wearer proximate the buttocks region. In various embodiments, the feminine absorbent article 100 can have a length as measured in the longitudinal direction (L) between the transverse direction upper and lower edges 110A and 110B, and the front portion 100A can be defined as the front third of the length of the feminine absorbent article 100, the middle portion 100B can be defined as the middle third of the length of the feminine absorbent article 100, and the back portion 100C can be defined as the back third of the length of the feminine absorbent article 100. It should be appreciated that each of the front portion 100A, the middle portion 100B, and the back portion 100C can vary as deemed appropriate for use of the feminine absorbent article 100.

[0051] In various embodiments, the feminine absorbent article 100 can have a pair of wings 104 that extend outwardly from the feminine absorbent article 100 in the transverse direction T. The wings 104 can be folded down in a wing fold region and can cover over the edges of the wearer's panties, positioning the wings 104 between the edges of the wearer's panties and her thighs. The wings 104 can prevent contamination of the wearer's panties by forming a barrier along the edges of the panties. In various embodiments, the wings 104 can be extensions of the material that forms the topsheet layer 101 and / or the backsheet layer 102, such that the wings 104 can be of unitary construction with the feminine absorbent article 100. In various embodiments, the wings 104 can be constructed of a material similar to the topsheet layer 101, the backsheet layer 102, or a combination of these materials. In various embodiments, the wings 104 can be separate elements that are joined to the main body of the feminine absorbent article 100.

[0052] Each of the various components of the feminine absorbent article 100, and optional additional components, will be described in more detail next.

[0053] Top sheet layer

[0054] The topsheet layer 101 defines the wearer-facing surface of the feminine absorbent article 100, which can directly contact the body of the wearer, and is liquid permeable to receive bodily exudates. The topsheet layer 101 advantageously provides comfort and conformance, and functions to channel bodily exudates through its own structure and away from the body toward the absorbent core 103. The topsheet layer 101 advantageously retains little or no liquid in its structure, such that it provides a relatively comfortable and non-irritating surface next to the skin of the wearer of the feminine absorbent article 100.

[0055] The topsheet layer 101 can be a single layer of material, or alternatively can be multiple layers that are compounded together. The topsheet layer 101 can be constructed of any material, for example, one or more woven sheets, one or more fibrous nonwoven sheets, one or more film sheets (e.g., blown or extruded films, which themselves can have single or multiple layers), one or more foam sheets (e.g., reticulated, open cell, or closed cell foams), coated nonwoven sheets, or combinations of any of these materials. Such combinations can be adhesively, thermally, or ultrasonically laminated into unitary planar sheet structures to form the topsheet layer 101.

[0056] In various embodiments, the topsheet layer 101 can be constructed from a variety of nonwoven webs, such as meltblown webs, spunbond webs, hydroentangled hydro-entangled spunlace webs, or air-through bonded carded webs. Examples of suitable topsheet layer 101 materials can include, but are not limited to, natural fiber webs (such as cotton), rayon, hydroentangled webs, bonded carded webs of polyester, polypropylene, polyethylene, nylon or other heat-bondable fibers (such as bicomponent fibers), polyolefins, copolymers of polypropylene and polyethylene, linear low density polyethylene, and aliphatic esters such as polylactic acid. Apertured films and web materials can also be used, as can laminates of these materials or combinations thereof.

[0057] In various embodiments, the topsheet layer 101 can include a plurality of apertures (not shown) formed therethrough to allow bodily exudates to more easily transfer into the absorbent core 103. The apertures can be randomly or uniformly arranged throughout the topsheet layer 101. The size, shape, diameter, and number of apertures can vary to meet the specific needs of the feminine absorbent article 100.

[0058] In various embodiments, the topsheet layer 101 can have a basis weight ranging from about 5, 10, 15, 20, or 25 gsm to about 50, 100, 120, 125, or 150 gsm. For example, in one embodiment, the topsheet layer 101 can be constructed from an air-through bonded carded web having a basis weight ranging from about 15 gsm to about 100 gsm. In another example, the topsheet layer 101 can be constructed from an air-through bonded carded web having a basis weight ranging from about 20 gsm to about 50 gsm.

[0059] In various embodiments, the topsheet layer 101 can be at least partially hydrophilic. In various embodiments, a portion of the topsheet layer 101 can be hydrophilic, and a portion of the topsheet layer 101 can be hydrophobic. In various embodiments, the portion of the topsheet layer 101 that can be hydrophobic can be a material that is inherently hydrophobic, or can be a material that is treated with a hydrophobic coating.

[0060] In various embodiments, the topsheet layer 101 can be a multi-component topsheet layer 101, such as by having two or more different nonwoven or film materials, with the different materials being placed in separate locations in the transverse direction T of the feminine absorbent article 100. For example, the topsheet layer 101 can be a two-layer or multi-component material having a central portion positioned along and straddling the longitudinal axis LI of the feminine absorbent article 100, with lateral portions flanking and bonded to each of the lateral edges of the central portion. The central portion can be constructed from a first material, and the lateral portions can be constructed from a material that can be the same or different than the material of the central portion.

[0061] Absorbent core

[0062] An absorbent core 103 can be positioned between the topsheet layer 101 and the backsheet layer 102. The absorbent core 103 can generally be any single layer structure or combination of layer components that can exhibit some degree of compressibility, conformability, lack of irritation to the wearer's skin, and ability to absorb and retain liquids and other body exudates. Additionally, the absorbent core 103 can provide additional capability to absorb and retain body exudates such as menses. In various embodiments, the absorbent core 103 can be formed from a variety of different materials and can include any number of desired layers. For example, the absorbent core 103 can include one or more layers (e.g., two layers) of absorbent web material: cellulose fibers (e.g., wood pulp fibers), other natural fibers, synthetic fibers, woven or nonwoven sheets, scrim webs or other stabilizing structures, superabsorbent material, binder materials, surfactants, selected hydrophobic and hydrophilic materials, pigments, lotions, odor control agents, and the like, as well as combinations thereof. In one embodiment, the absorbent web material can include a matrix of cellulose fluff and can also include superabsorbent material. The cellulose fluff can include a blend of wood pulp fluff.

[0063] In various embodiments, the absorbent core 103 can include optional amounts of superabsorbent material, if desired. Examples of suitable superabsorbent materials can include poly(acrylic acid), poly(methacrylic acid), poly(acrylamide), poly(vinyl ether), copolymers of maleic anhydride with vinyl ether and alpha-olefins, poly(vinyl pyrrolidone), poly(vinyl morpholinone), poly(vinyl alcohol), and salts and copolymers thereof. Other superabsorbent materials can include unmodified and modified natural polymers, such as hydrolyzed acrylonitrile grafted starch, acrylic acid grafted starch, methyl cellulose, chitosan, carboxymethyl cellulose, hydroxypropyl cellulose, and natural gums such as algin, xanthan gum, locust bean gum, and the like. Mixtures of natural and wholly or partially synthetic superabsorbent polymers can also be used. The superabsorbent material can be present in the absorbent core 103 in any amount as desired.

[0064] The shape of the absorbent core 103 can vary as desired and can include any of a variety of shapes, including but not limited to triangular, rectangular, dog-bone, and oval shapes. In various embodiments, the absorbent core 103 can have a shape that generally corresponds to the overall shape of the feminine absorbent article 100. The dimensions of the absorbent core 103 can be substantially similar to the dimensions of the feminine absorbent article 100, but it should be understood that the dimensions of the absorbent core 103 will often be smaller than the dimensions of the overall feminine absorbent article 100 at the same time in order to fit substantially within.

[0065] As described above, in various embodiments, the absorbent core 103 can be a single layer construction and can include a matrix of, for example, cellulose fluff and superabsorbent material. In various embodiments, the absorbent core 103 can have at least two layers of material, such as a body-facing layer and a garment-facing layer. In various embodiments, the two layers can be the same as one another. In various embodiments, the two layers can be different from one another. In such embodiments, the two layers can provide different absorbent properties to the feminine absorbent article 100 as deemed appropriate. In various embodiments, the body-facing layer of the absorbent core 103 can be constructed of an air- through material and the garment-facing layer of the absorbent core 103 can be constructed of a compressed sheet containing superabsorbent polymer. In such embodiments, the air-through material can have a basis weight from about 40 gsm to about 200 gsm and the compressed sheet containing superabsorbent polymer can be a cellulose fluff based material which can be a combination of cellulose pulp and SAP encapsulated by a tissue carrier and having a basis weight of about 40 gsm to about 400 gsm, such as Figure 1 as indicated by 103A in FIG. 1.

[0066] Backsheet layer

[0067] The backsheet layer 102 is substantially liquid impermeable and is the portion of the feminine absorbent article 100 that faces the wearer's clothing. The backsheet layer 102 can permit the flow of air or vapor out of the feminine absorbent article 100 while still resisting the passage of liquids. Any liquid impermeable material can generally be used to form the backsheet layer 102. The backsheet layer 102 can be constructed of a single layer or multiple layers, and these one or more layers can themselves include similar or different materials. Suitable materials that can be used can be microporous polymeric films, such as polyolefin films of polyethylene or polypropylene, nonwovens and nonwoven laminates, and film / nonwoven laminates. The particular structure and composition of the backsheet layer 102 can be selected from a variety of known films and / or fabrics, with particular materials being suitably chosen to provide the desired level of liquid barrier, strength, abrasion resistance, tactile properties, aesthetics, etc.

[0068] In various embodiments, a polyethylene film can be used, which can have a thickness in the range of from about 0.2 or 0.5 mils to about 3.0 or 5.0 mils. An example of the backsheet layer 102 can be a polyethylene film. Another example can include a polypropylene film filled with calcium carbonate. In yet another embodiment, the backsheet layer 102 can be a hydrophobic nonwoven material having water barrier properties, for example, a nonwoven laminate, an example of which can be a four layer spunbond-meltblown-meltblown-spunbond laminate. Thus, the backsheet layer 102 can have a single layer or multiple layer construction, for example, having multiple film layers or a laminate of film layers and nonwoven fiber layers.

[0069] Optional additional components

[0070] In various embodiments, the feminine absorbent article 100 can optionally include at least one of a fluid intake layer, a transfer delay layer, a gush layer, and / or a distribution layer positioned between the topsheet layer 101 and the backsheet layer 102.

[0071] Fluid intake layer

[0072] In various embodiments, the feminine absorbent article 100 can include a liquid permeable fluid intake layer (not shown) positioned between the topsheet layer 101 and the absorbent core 103. Such a fluid intake layer can be made of a material capable of quickly transferring bodily exudates delivered to the topsheet layer 101 in the Z-direction. The fluid intake layer can generally have any desired shape and / or size. For example, the fluid intake layer can have a length of between about 20 mm to about 300 mm and can take a width of between about 10 mm to about 100 mm. The fluid intake layer can have a thickness in the vertical direction of from about 0.5 mm to about 3 mm. Any of a variety of different materials can be used for the fluid intake layer. The material can be synthetic, cellulosic, or a combination of synthetic and cellulosic materials. The fluid intake layer can be constructed of any woven or nonwoven material. For example, the fluid intake layer can be constructed as an air- through or TABCW material. For example, an air-through cellulose tissue can be suitable for the fluid intake layer. The air-through cellulose tissue can have a basis weight ranging from about 10 gsm or 100 gsm to about 250 gsm or 300 gsm. The air-through cellulose tissue can be formed of hard wood and / or soft wood fibers. The air-through cellulose tissue can have a fine pore structure and can provide excellent wicking capacity, particularly for menses.

[0073] As Figure 1As shown, to further enhance the ability of the female absorbent article 100 to transfer bodily fluids from the top layer 101 to any lower layer of the female absorbent article 100 in the depth direction (Z), and to enhance the ability of the fluid-absorbing layer to conform to the wearer's body based on its flexibility, a core absorbent region 113 for fluid penetration is provided. This core absorbent region can be achieved, for example, by perforating the preferably cotton-containing absorbent core. More specifically, this core absorbent region 113 defines an area of ​​the female absorbent article 100 for absorbing bodily fluids such as menstrual blood in a short period of time, where it has a higher menstrual blood absorption capacity than other parts. Although the core absorbent region 113 shown here is oval, those skilled in the art will understand that the core absorbent region 113 can be any suitable shape, such as circular, rectangular, square, triangular, etc. In various embodiments, the core absorbent region 113 in the fluid-absorbing layer can be elongated and can be oriented in the longitudinal direction (X) of the female absorbent article 100. The core absorbent area 113 may also be formed into a cup-shaped or well-shaped structure to retain bodily excretions and prevent them from moving away from the area of ​​the female absorbent product 100 and leaking towards the edge of the female absorbent product 100.

[0074] Depending on the primary location of bodily effusion aspiration or the intended use of the feminine absorbent article 100, the core absorbent region 113 may be located at different positions along the longitudinal and transverse directions of the fluid aspiration layer. For example, in various embodiments, the fluid aspiration layer and the core absorbent region 113 may be positioned such that they are substantially aligned with the longitudinal central axis L1 and the transverse axis T1 of the feminine absorbent article 100. This allows the core absorbent region 113 to be centrally positioned, allowing it to be located below the primary point of bodily effusion discharge and to function as the primary bodily effusion receiving area of ​​the feminine absorbent article 100. Here, the core absorbent region 113 may have a longitudinal length from about 15 mm to about 180 mm and a transverse width from about 10 mm to about 40 mm.

[0075] Furthermore, as an optional but not essential design aspect, the female absorbent article 100 may also have one or more lateral deflectors 114, as shown herein. Figure 1 The lateral deflector 114 is preferably designed as, for example, a closed or semi-closed shape. The lateral deflector 114 can be arranged around the core absorbent region 113 in the central region of the feminine absorbent article 100 to prevent lateral leakage when excessive bodily fluids or menstrual blood cannot easily seep down through the core absorbent region 113 in a short time. For example, Figure 1 As shown. The lateral deflector 114 can be manufactured by adding rigid material, embossing, grooves, perforations, channels, and combinations thereof. In various embodiments, the lateral deflector 114 can be manufactured by embossing one or more elements of the female absorbent article 100.

[0076] Transfer delay layer

[0077] In various embodiments, the feminine absorbent article 100 can include a liquid permeable transfer delay layer (not shown) positioned below the topsheet layer 101 in the depth (Z) direction. The transfer delay layer can comprise a substantially hydrophobic material. For example, the transfer delay layer can be a nonwoven web composed of a relatively hydrophobic material such as polypropylene, polyethylene, polyester, and the like, and can also be composed of a blend of such materials. One example of a suitable material for the transfer delay layer can be a spunbond web composed of polypropylene multilobal fibers. Additional examples of suitable transfer delay layer materials can include spunbond webs composed of polypropylene fibers that can be round, tri-lobal, or multilobal in cross-sectional shape and hollow or solid in structure. Typically, the web is bonded, such as by thermally bonding over about 3% to about 30% of the web area.

[0078] Gush layer

[0079] Additional layers between the topsheet layer 101 and the absorbent core 103 can include a well-known surge layer. The surge layer (not shown) can be constructed from any woven or nonwoven material that is readily penetrated by bodily exudates. The surge layer can help to absorb, decelerate, and spread surges or gushes of liquid that can be quickly introduced into the feminine absorbent article 100. The surge layer can quickly receive and temporarily retain liquid before releasing the liquid into, for example, the absorbent core 103 or any other layer of the feminine absorbent article 100. Various woven fabrics and nonwoven webs can be used to construct the surge layer. For example, the surge layer can include a nonwoven fabric layer composed of a meltblown or spunbond web of polyolefin or polyester filaments. Such nonwoven fabric layers can include conjugate, bicomponent, and homopolymer fibers of various lengths or other lengths, as well as mixtures of such fibers with other types of fibers. The surge layer can also be a bonded carded web or an air-laid web composed of natural and / or synthetic fibers. The bonded carded web can be, for example, a powder bonded carded web, an infrared bonded carded web, or an air-through bonded carded web. The bonded carded web can optionally include a mixture or blend of different fibers. The surge layer typically has a basis weight of less than about 100 gsm and in some embodiments from about 10 gsm to about 40 gsm.

[0080] Distribution layer

[0081] The absorbent system can have a distribution layer (not shown) positioned below the absorbent core 103. The distribution layer can increase the absorbency of the feminine absorbent article 100. The distribution layer can be composed of a variety of materials such as, but not limited to, a hydroentangled web, an air-through bonded carded web, a meltblown web, and a meltblown microfiber web. The distribution layer can include a hydrophilic material. The distribution layer can be smaller in size than the absorbent core 103 of the feminine absorbent article 100. In various embodiments, the distribution layer can have a longitudinal length greater than 50 mm, preferably from about 80 mm to about 190 mm, and can have a transverse width from about 30 mm to about 60 mm. In various embodiments, the distribution layer can have a basis weight from about 10 gsm to about 200 gsm.

[0082] Wing

[0083] The inventors of the present utility model found that the main reason for the unsatisfactory experience of the existing feminine absorbent articles (such as shown in Figure 1 and Figure 2 ) lies in the design of the shape, size and position of the wings, and thus it would be helpful to improve the user experience, comfort and leakage prevention of the feminine absorbent article by optimizing the above aspects of the wings in the prior art.

[0084] Specifically, the inventors found that the shape and size design of the wings of the existing feminine absorbent articles are not good enough, for example, due to the excessive length of the wings, the wings themselves hinder the product from being attached to the center of the crotch of the underpants, or when the wings are folded to the bottom of the underpants, the wings appear messy roll edges in front and back, causing discomfort or poor fixation problems during wearing. Further, the obtuse angle design between the wings and the main body of the article makes it difficult to effectively fold and fix the wings, or causes the wings to curl and stick to themselves during folding. At the same time, due to the insufficient width of the wings, after being folded to the bottom of the underpants, the wings cover a limited area of the underpants, resulting in poor fixation of the wings and displacement during use. Finally, the position design of the wings relative to the main body of the article is not good enough, and the wings in the existing products are too forward or too backward, causing the center of the absorbent article to deviate far from the discharge port after the product is attached to the underpants, leading to leakage problems due to reduced absorption efficiency.

[0085] The inventors of the present utility model in order to solve the above-mentioned various deficiencies, specially put forward the wings 104 shown in Figure 1 and 2 . Specifically, as shown in Figure 1 and 1A , a pair of wings 104 respectively extend outward from the opposite longitudinal direction side edges 111A and 111B of the absorbent article 100 in the transverse direction on both sides of the absorbent article 100. Here, the wings 104 are not via the narrowing portion 104A (inFigure 1 and 1A The narrowing 104A is only indicated on the left side of the figure, but the same design is present on the right side) is fixedly connected to the corresponding part of the absorbent article 100. In Figure 1 and 1A The article body 106 shown in

[0086] In Figure 1 and 1A The wings 104 shown herein have the narrowing 104A designed to have a length dl in the longitudinal direction L in the range of 40 to 70 mm, preferably in the range of 45 to 50 mm. The inventors of the present application have found that the narrowing 104A will serve as a folding area for folding the wings 104 towards the crotch portion of the panty when the female absorbent article 100 is fixed to the crotch portion of the panty as described hereinafter. Since the crotch portion of the panty is designed as an arc 1041 widening from the narrowest portion to both sides, when the length of the narrowing 104A is designed to be too large, the substantially vertically extending narrowing 104A is difficult to conform to the arc of the crotch portion of the panty well at all times, which tends to cause the wings 104 to be rolled or misaligned during folding towards the crotch portion of the panty and thus affect the fixation of the female absorbent article 100. At the same time, since the narrowing 104A is used to ensure the connection strength and rigidity between the article body 106 and the wings 104, if the length of the narrowing 104A is too small, the connection strength or rigidity of the wings 104 tends to be insufficient, thus causing the wings 104 to be broken away from the article body 106 when the disposable absorbent article 100 is removed and discarded. After careful research and repeated tests on the current panty design for women, the inventors have confirmed that it is satisfactory to design the length dl of the narrowing 104A in the longitudinal direction L to be in the range of 40 to 70 mm, preferably in the range of 45 to 50 mm.

[0087] As shown in Figure 1 and 1A The narrowing 104A shown herein defines an opening between the longitudinal direction side edge 111A of the article body 106 that gradually increases towards the upper edge 110A and the lower edge 110B in the transverse direction, respectively, wherein the opening is shown in Figure 1 and 1A has substantially V-shaped edges, wherein the included angle a between the two edges of the V-shaped opening is in the range of about 10 to 80 degrees, preferably in the range of 30 to 40 degrees. Herein, as shown in Figure 1As shown, the gradually widening, slightly curved edges of the narrowed portion 104A are linearly fitted to create an angle α between the two intersecting lines. Thus, with the help of the V-shaped opening with this acute-angle design, the edges of the main body 106 and the protective wing 104... Figure 5 and 1A The relative movement in the left-right direction (lateral direction T direction), especially the movement of the wing 104 relative to the main body 106 of the product in the T direction, becomes free. As a result, when the absorbent product 100 is fixed to women's underwear (e.g., ...), the relative movement in the left-right direction (lateral direction T direction), especially the movement of the wing 104 relative to the main body 106 of the product in the T direction, becomes free. Figure 1 As shown, the narrowing portion 104A also functions as a guide when bending the wing 104 relative to the main body 106 along the two sides of the inner thigh of the woman's underwear, making bending and fixing easier. Therefore, the sharp-angled V-shaped opening design and the narrowing portion 104A of a selected length together reduce the area of ​​the wing 104 that contacts the skin of the inner thigh, thereby reducing the area of ​​friction between the thigh and the wing 104 during human activity, thus reducing the possibility of the wing 104 curling or self-adheding after human activity. As a result, the synergistic effect of the sharp-angled V-shaped opening design and the aforementioned narrowing portion 104A of a selected smaller length allows the wing 104 to not only avoid causing discomfort to the wearer's inner thigh or surrounding area, but also avoids reducing the absorbency of the absorbent article 100 or causing leakage of bodily fluids.

[0088] Further, the wing 104 has a base end 104D or root adjacent to the narrowing 104A and located inward in the transverse direction T relative to the transverse axis T1 (which is adjacent to the article body 106, in particular to the portion of the article body 106 where the side edges intersect the transverse axis T1), and a top end 104C located outwardmost in the transverse T relative to the transverse axis T1, whereby a width w1 of the wing 104 is defined in the transverse direction between the top end 104C and the narrowing 104A having a length d1 in the longitudinal direction L. The width w1 of the wing 104 in the transverse direction T is designed herein to be in the range of 25 to 70 mm, preferably in the range of 35 to 50 mm. The inventors of the present application have found that the width w1 of the wings 104 arranged on opposite sides of the article body 106 in the transverse direction T serves as an area to fit against the crotch portion of the panty when the female absorbent article 100 is fixed to the crotch portion of the panty. Therefore, in order to ensure that the wings 104 have a fitting area covering the crotch portion of the panty sufficient to ensure the fixation, the width w1 of the wings 104 is not less than 25 mm, preferably not less than 35 mm. At the same time, the inventors have also found that when the width of the wings 104 is designed to be between 40 mm and 50 mm, the width w1 of the wings 104 on opposite sides is sufficient to mutually superimpose to 100% cover the crotch portion of the panty in a self- embracing or self-hugging manner, which has the most ideal fixation. Of course, if the width w1 of the wings 104 is too large to be greater than the width of the crotch portion of the panty, on the one hand, the material cost and the processing difficulty of the wings 104 are unnecessarily increased, and on the other hand, the possibility of misbonding between the back adhesive 105 on the wings 104 on opposite sides is increased, which increases the possibility of misoperation by the consumer and complicates the use of the wings 104. After careful research and repeated tests by the inventors, it is confirmed that it is satisfactory to design the width w1 of the wings 104 in the transverse direction T to be in the range of 25 to 70 mm, preferably in the range of 35 to 50 mm.

[0089] Further, as Figure 1 and 1AAs shown, the wing 104 has a widened portion 104B in a region generally in the middle of its width in the transverse direction T, which has the largest length dimension d2 in the longitudinal direction L among the entire wing 104, and the length dimension d2 of the widened portion 104B in the longitudinal direction L is designed to be no greater than 150 mm, preferably in the range of 50 mm to 80 mm. Here the widened portion 104B and the narrowed portion 104A are connected by means of a gradually expanding smooth curve 1041 and connected between the tip portion 104C and the widened portion 104B by means of a gradually tapering arc-shaped curve 1043, and the smooth curve 1041 and the arc-shaped curve 1043 converge at the vertex 1042 of the widened portion 104B with the largest length dimension d2, so that the wing 104 is designed in particular in the shape of a "mushroom head", which is believed to bring a pleasant sensory stimulation to the consumer. At the same time, in the case of applying the back adhesive 105 to the vicinity of the widened portion 104B in the wing 104, such a design enables the consumer to intuitively use the widened portion 104B as a grip when peeling the back adhesive 105 of the wing 104 from the consumer's underpants, which in turn makes it easy and intuitive for the consumer to peel the back adhesive 105 of the wing 104 from the underpants.

[0090] The inventor of the present utility model finds that the length dimension d2 of the widened portion 104B defines the longest length and the approximate position for arranging the back adhesive 105, and the length for conforming to the crotch length of the consumer's underpants. Therefore, in order to ensure that the wing 104 has a conforming area covering most of the length of the crotch of the underpants sufficient to ensure fixation, the length dimension d2 of the widened portion 104B is no less than 80 mm, preferably no less than 60 mm. Of course, if the length dimension d2 of the widened portion 104B is too large to be greater than the width of the crotch of the underpants, on the one hand, it unnecessarily increases the material cost and processing difficulty of the wing 104, and on the other hand, it can increase the possibility of curling or self-sticking when the wing 104 is folded and complicate the use of the wing 104. After careful research and repeated testing by the inventor, it is confirmed that it is satisfactory to design the length dimension d2 of the widened portion 104B in the longitudinal direction L to be no greater than 150 mm, preferably in the range of 50 mm to 80 mm.

[0091] Preferably, in order to ensure that the core absorption regions 113 in the article body 106 for the percolation of body fluids or menstrual blood and the core absorption area defined by these core absorption regions 113 can be generally aligned with the discharge opening of the consumer's body, the wing 104 is preferably arranged relative to the article body 106 at a position where the middle line (in the longitudinal direction L) of the wing 104 is preferably in the range of 10 mm to 30 mm, more preferably in the range of 15 mm to 25 mm, relative to the middle line (in the longitudinal direction L) of the article body 106. Figure 1 and 1AThe distance D1 from the transversal direction edge 110A is in the range of 90 mm to 210 mm, preferably in the range of 100 mm to 200 mm.

[0092] The inventors of the present utility model found that the general consumers are used to taking the wings 104 as the reference datum for laying the female absorbent article 100 in the crotch part of the underpants, i.e. they are used to laying the wings 104 in the narrowest section of the crotch part of the underpants. The existing female absorbent articles often design the wings to be located at the front part of the absorbent article or close to the front part, which makes the consumers easily lay the female absorbent article in the back of the underpants when using, and the result is that the opening for receiving the large flow of body fluid or menstrual blood and the core absorbent area defined by the core absorbent area 113 are not located in the position aligned or substantially aligned with the discharge opening of the consumer's body, thereby causing the menstrual blood to leak to the side or front of the front part of the absorbent article.

[0093] By means of the "fool-proof" design of laying the wings 104 at a distance D1 of a certain length from the transversal direction edge 110A as shown in Figure 2 and 1A , the consumers can directly and correctly lay the female absorbent article 100 in the underpants in the proper manner in the front and back directions at a position where the discharge opening of the consumer is in the area covered by the core absorbent area 113 for the menstrual blood to infiltrate, without the need for rich experience or high attention, thereby significantly reducing the possibility or probability of the menstrual blood leaking to the side or front of the front part of the absorbent article.

[0094] Another embodiment according to the present utility model is shown in Figure 2 and 2A , wherein the same components are denoted by the same reference numerals.

[0095] Figure 1 and 2A , the difference between the female absorbent article 100 and the embodiment shown in Figure 2 and 1A mainly lies in the shape and size design of the wings 104 itself. Specifically, in Figure 1 and 2A , the outer contour of the wings 104 is designed from the "mushroom" shape in Figure 2 and 1A to the "petal" shape in Figure 2 and 2A . To this end, the included angle a enclosed by the two side edges of the V-shaped opening of the wings 104 in Figure 1 and 2A is larger than that in Figure 3 and 1AThe angle a in the wing 104 is increased, and the angle a is in the range of 30 to 45 degrees. Meanwhile, the width w1 of the wing 104 in the transverse direction T is designed in the range of 50 to 80 mm, preferably 65 mm. Further, the maximum length dimension d2 of the wing 104 in the longitudinal direction L is also increased, and the length dimension d2 is in the range of 70 to 80 mm.

[0096] In Figure 2 the use state of the embodiment in Figure 4 and 2A is shown, and because the width w1 of the wing 104 in the transverse direction T is designed in the range of 50 to 80 mm, the wings 104 on both sides of the article body 106 are stacked on each other to 100% cover the crotch of the underpants in a self-encircling or self-hugging manner, which has the most ideal fixation.

[0097] Next, the use method of the female absorbent article 100 of the present application is described in combination with Figure 5 and Figure 4 .

[0098] In Consumer test for measuring perceived overall liking and stickiness the underpants of a consumer to which the female absorbent article 100 is to be attached are shown, wherein the underpants have a front piece 11 corresponding to the belly of the consumer and a back piece 12 corresponding to the buttocks of the consumer and a crotch region 13 between the front piece 11 and the back piece 12, wherein the crotch region 13 has a narrowest width K1 in the range of, for example, 35 to 75 mm.

[0099] In use of the female absorbent article 100 according to the present application, the female absorbent article 100 is first opened to an elongated shape from the wrapped and folded state, and then the release paper for preventing the adhesive 105 from being attached is torn off, and the wings 104 on both sides of the article body 106 are placed at the narrowest width K1 in the range of, for example, 35 to 75 mm of the crotch region 13. Then, the wings 104 on both sides are folded towards the crotch region 13 along the narrowed portion 104A of the wings 104 until the adhesive 105 in the wings 104 reliably adheres to the crotch region 13. Based on the above description, the operation of fixing the female absorbent article 100 according to the present application is simple and the situation of "curling" or "poor fixation" in the prior art is unlikely to occur. Meanwhile, due to the position design of the wings 104, the body excretion opening of the consumer is located in the area covered by the core absorption region 113 of the fixed female absorbent article 100, which improves the comfort and leakage prevention of the product during use.

[0100] Figure 1

[0101] To understand the overall preference of consumers on different wing designs on female absorbent articles ("samples including the female absorbent article 100 of the present utility model"), 30 female panelists who have had a period in the past 6 months or have certain experience of using female absorbent articles (divided into a first group of 18 to 24 years old and a second group of 25 to 35 years old according to age span) were recruited. The samples of female absorbent articles with different wing designs were shown to these panelists. They were asked to rate the samples on overall liking and purchase intent on a 1-10 scale (a score of "1" means extremely dislike, a score of "6" means acceptable, and a score of "10" means extremely like). Then the average overall liking score and purchase intent of each sample were calculated and reported with standard deviation. Secondly, these panelists were asked to fix the provided samples to the crotch of the underpants in a simulated actual use state to evaluate the convenience of folding the wings of such samples.

[0102] From the results of the test, more than 80% of the women prefer the "mushroom-shaped" and "petal-shaped" wings 104 with the narrowing part and the widening part shown in the product design of the female absorbent article 100 according to the embodiments in the present utility model Figure 2 and 1A and ​ and 2A The product design of the female absorbent article 100 with the "mushroom-shaped" and "petal-shaped" wings 104 with the narrowing part and the widening part shown in the embodiments in the present utility model was evaluated, and such wings 104 were evaluated as more humanized, better fitting, easier to fold, etc.
