Description

[Technical Field]

[0001] The present invention relates to an individual package for absorbent articles. [Background technology]

[0002] Generally, absorbent articles are composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between them. For example, light incontinence products are used by fastening the back sheet side to underwear.

[0003] The task of replacing a used absorbent article (hereinafter also referred to as a "used article") with a new absorbent article (hereinafter also referred to as a "new article") is usually carried out by removing the used article from the underwear with both hands, storing the used article in a new packaging bag or the like for disposal, and then attaching the new absorbent article to the underwear. At this time, when removing the used article, the fingers come into direct contact with the used article, and body fluids are likely to adhere to the fingers. Furthermore, when storing a used article that has absorbed body fluids and has expanded and / or deformed in a new packaging bag, part of the used article may get caught on a cut or the like in the packaging bag, staining the fingers with body fluids. Furthermore, storing the used article in a packaging bag or the like does not mean that the used article is sealed, and there is a risk that body fluids may leak along the inner surface of the packaging bag and adhere to clothing or the like.

[0004] Some people also wrap used products in toilet paper instead of packaging bags before discarding them, but toilet paper does not have sufficient water resistance or sealing properties, which can easily lead to problems such as the rolled-up package opening and exposing the used product, or bodily fluids leaking out and tearing the package, or bodily fluids dropping onto the floor of the toilet stall.As such, there is a demand for individual absorbent article packages that allow used products to be replaced with new ones in a clean manner without soiling the hands or the toilet stall with bodily fluids, and that can seal the used product, and various proposals have been made.

[0005] Patent Document 1 describes an absorbent article including an absorbent article such as a disposable diaper or napkin, and a Z-shaped adhesive tape, the Z-shaped adhesive tape being folded into a Z shape in a side view and having a portion (a), a portion (b) connected to portion (a), and a portion (c) connected to portion (b), wherein a release-treated layer is provided on the outer surface of portion (a) and 50% or less of the surface of portion (b), a release-treated layer is not present on the inner surface of portion (c), and an adhesive layer is provided on at least the inner surface of portion (a) and / or the outer surface of portion (c), and the Z-shaped adhesive tape is fixed to the outer surface of the absorbent article by the adhesive layer provided on portion (c) (Claim 1, Claim 16). Patent Document 1 also describes that a used absorbent article can be rolled up and fixed with the Z-shaped adhesive tape (Paragraph 0022). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 7-157728 Summary of the Invention [Problem to be solved by the invention]

[0007] The absorbent article described in Patent Document 1 is disposed of by rolling up the used article and sealing it with Z-shaped adhesive tape fixed to its outer surface, but this does not sufficiently prevent the used article from being exposed or from leaking bodily fluids. Furthermore, even if the used article is fixed with Z-shaped adhesive tape, it is necessary to touch the used article with one's fingers, making it difficult to prevent the fingers from being soiled with bodily fluids. Furthermore, since the Z-shaped adhesive tape is fixed directly to the absorbent article, there is a risk that the absorbent article may feel uncomfortable when worn.

[0008] The object of the present invention is to provide an absorbent article that allows a used absorbent article to be cleanly replaced with a new one without soiling the hands and fingers, that can be packaged without exposing the used absorbent article, and that can prevent leakage of bodily fluids. package The present invention provides a method for using the same.

By keeping each dimension within the aforementioned numerical ranges, an absorbent article 50 suitable for use as a light incontinence product, sanitary napkin, panty liners, and the like can be obtained.

[0016] The absorbent article of this embodiment package As shown in FIGS. 1 to 3, the body 1 includes an absorbent article 50 and,The absorbent article 50 is provided with a release sheet 71 releasably adhered to the surface closest to the skin (the surface closest to the skin of the back sheet 30 described later), an individual wrapping sheet 72 adhered to the surface closest to the skin of the release sheet 71, and a Z-shaped adhesive tape 70 adhered to the surface closest to the skin of the individual wrapping sheet 72. package The absorbent article 50 may have a flat storage bag (not shown) for storing the folded absorbent article 1. package Imaginary fold lines 61, 62 extending in the width direction and arranged in the longitudinal direction are set and are used when folding the absorbent article 1 into a product. The absorbent article 50 and its accessories (release sheet 71, individual packaging sheet 72, etc.) are folded along the fold lines 61, 62, placed in a packaging bag, and sealed, and then sold commercially.

[0017] The absorbent article 50 includes a liquid-permeable top sheet 10 located on the skin side, a liquid-impermeable back sheet 30 located opposite the top sheet 10 and on the non-skin side, an absorbent body 20 located between the top sheet 10 and the back sheet 30, a pair of three-dimensional gathers 40 provided at both widthwise ends of the skin-side surface of the top sheet 10, and a pair of liquid-impermeable side sheets 60 provided at both longitudinal ends of the skin-side surface of the top sheet 10. Note that this embodiment is not limited to the absorbent article 50, and any currently known absorbent article can be used without any particular limitation.

[0018] The Z-shaped adhesive tape 70 has an outer shape in which a strip is folded into a Z shape when viewed from the side, and has a first fold and a second fold that are spaced apart and extend widthwise from one end to the other in the longitudinal direction, and has an area A from one end to the first fold, an area B from the first fold to the second fold, and an area C from the second fold to the other end, and area A has an adhesive layer (a) (adhesive layer 75) on one surface and is fixed to the non-skin surface of the individual packaging sheet 72, area B has a hook tape (b) (hook tape 76) on the other surface opposite area A, and area C has an adhesive layer (c) (adhesive layer 77) on one surface on the same side as area A, and the free end 78 forms a tab.

[0019] According to this embodiment, a used absorbent article 50 (hereinafter also referred to as a "used article") attached to underwear on the back sheet 30 side is replaced with a new absorbent article 50 (hereinafter also referred to as a "new article") and an individual packaging sheet 72 having a Z-shaped adhesive tape 70 fixed to one surface and wrapping the used article so as not to expose it. First, the Z-shaped adhesive tape 70 is unfolded to attach the hook tape 76 in Region B to the surface of the top sheet 10 of the used article, and the individual packaging sheet 72 is placed over the used article. The used article can then be removed from the underwear through the individual packaging sheet 72 and hermetically packaged in the individual packaging sheet 72. At this time, if Region C of the Z-shaped adhesive tape 70 is led outward from the packaging, the packaging can be sealed with the adhesive layer 77 in Region C. Therefore, according to this embodiment, the replacement of the used article with a new one can be performed very cleanly and easily without soiling hands, clothes, the toilet floor, etc. with bodily fluids and without exposing even a portion of the used article.

[0020] Furthermore, in an embodiment in which a new absorbent article and an individual packaging sheet 72 having a Z-shaped adhesive tape 70 fixed to one surface are integrated with a release sheet 71 or the like, the release sheet 71 is configured to be peelable from the new absorbent article, so that the used absorbent article 50 can be packaged in a two-layer sheet consisting of the release sheet 71 and the individual packaging sheet 72, thereby further improving the cleanliness of hands and the packaging ability of the used absorbent article 50.

[0021] As described above, the absorbent article of this embodiment package The body 1 includes an absorbent article 50, a release sheet 71, an individual wrapping sheet 72, and a Z-shaped adhesive tape 72, and the absorbent article 50, the individual wrapping sheet 72, and the Z-shaped adhesive tape 70 are basic constituent units.

[0022] The absorbent article 50 of this embodiment has a top sheet 10, an absorbent body 20, and a back sheet 30 as basic constituent units, and can be modified in various known ways, such as providing the above-mentioned three-dimensional gathers 40 and side sheets 60, arranging a second sheet or transfer sheet (not shown) between the top sheet 10 and the absorbent body 20, or covering the absorbent body 20 with a carrier sheet (not shown). Below, the constituent members of the absorbent article 50 of this embodiment will be described in more detail in the order of the top sheet 10, the absorbent body 20, the back sheet 30, the three-dimensional gathers 40, and the side sheets 60.

[0023] <Top sheet> The top sheet 10 is a liquid-permeable sheet-like substrate that allows bodily fluids to pass quickly toward the absorbent body 20 and diffuse the bodily fluids in the plane direction of the absorbent body 20. The top sheet 10 is preferably a substrate that is soft to the touch and does not irritate the skin so that it may come into direct contact with the wearer's skin. Examples of such substrates include hydrophilic sheets, composite nonwoven fabrics that are laminates of the same or different hydrophilic sheets, apertured films such as apertured polyethylene films, and foamed films such as polyethylene foam and urethane foam. Examples of hydrophilic sheets include air-through nonwoven fabrics, thermal-bonded nonwoven fabrics, spunlace nonwoven fabrics, and spunbonded nonwoven fabrics made from synthetic fibers made of synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton. Among these, the various nonwoven fabrics are preferred.

[0024] The surface of the top sheet 10 may be embossed or perforated to improve liquid permeability. The top sheet 10 may contain one or more of lotions, antioxidants, anti-inflammatory ingredients, pH adjusters, antibacterial agents, moisturizers, etc. to reduce irritation to the skin. The basis weight of the top sheet 10 is set to, for example, 15 g / m² from the viewpoints of strength, processability, and liquid wetting-back. 2 More than 40g / m 2 The following range or 19g / m 2 More than 35g / m 2The shape of the top sheet 10 is not particularly limited, and may be any shape that covers part or all of the absorbent body 20, which is necessary to guide bodily fluids to the absorbent body 20 without leakage.

[0025] <Absorbent> The absorbent body 20 has a longitudinal dimension (maximum length) in the range of, for example, 100 mm to 800 mm, 150 mm to 500 mm, or 270 mm to 500 mm. The widthwise dimension (maximum width) of the absorbent body 20 is, for example, 50 mm to 500 mm, 60 mm to 400 mm, or 70 mm to 105 mm. When the absorbent body 20 has an hourglass-shaped planar shape, the longitudinal dimension is in the range of 180 mm to 800 mm, the widthwise dimensions of the front and rear portions that contact the wearer's abdomen and back, respectively, are both in the range of 60 mm to 400 mm, and the widthwise dimension of the central portion that contacts the wearer's crotch is in the range of 90 mm to 250 mm. Examples of planar shapes of the absorbent body 20 include an hourglass shape, an I-shape, a rectangle, a rounded rectangle, and an oval. The absorbent body 20 may be, for example, a fluff absorbent body containing absorbent fibers and a superabsorbent polymer.

[0026] (absorbent fiber) The absorbent fiber is not particularly limited as long as it is one generally used in absorbent articles such as sanitary napkins, disposable diapers, and urine absorption pads, and examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabric. Among these, fluff pulp is preferably used from the viewpoint of absorbency. Examples of fluff pulp include wood pulp (e.g., bleached coniferous kraft pulp (N-BKP) such as southern pine or Douglas fir), synthetic fiber, resin fiber, and non-wood pulp defibrated into a cotton-like state. When fluff pulp is used as the absorbent fiber base material in the absorber 20, the basis weight of the absorbent fiber is, for example, 100 g / m2 from the viewpoint of feel on the skin, body fluid absorption capacity, and the like. 2 More than 800g / m 2 The following range: 325g / m2 More than 615g / m 2 The range is as follows:

[0027] (Superabsorbent polymer) The superabsorbent polymer (hereinafter also referred to as "SAP") is not particularly limited as long as it can absorb body fluids and prevent backflow, and examples thereof include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponified products thereof. Among these, from the viewpoint of absorption per weight, polyacrylates are preferred, alkali metal polyacrylates are more preferred, and sodium polyacrylate is even more preferred. The superabsorbent polymers can be used alone or in combination of two or more.

[0028] The superabsorbent polymer is used in various forms, such as particulate or fibrous, but is preferably used in particulate form for ease of handling. By avoiding the use of a finely powdered superabsorbent polymer with poor powder flowability and using a superabsorbent polymer with a median particle size, basic absorption performance can be improved and the rough feel that occurs when the absorbent body 20 hardens after absorbing body fluids can be reduced. The median particle size of the superabsorbent polymer 12 is, for example, in the range of 50 μm to 600 μm or in the range of 100 μm to 500 μm. The content of the superabsorbent polymer in the absorbent body 20 is in the range of 40 wt % or more, or in the range of 40 wt % to 70 wt % of the total weight of the absorbent body 20.

[0029] In the absorbent body 20, the absorbent fibers and SAP may be in the form of a mixture of SAP particles in absorbent fibers, or an SAP sheet in which SAP particles are fixed between absorbent fibers. In addition to the fluff absorbent body described above, the absorbent body 20 may also be an absorbent sheet containing multiple hydrophilic sheets with a superabsorbent polymer fixed and supported between them. To prevent leakage of SAP particles from the absorbent body 20 and to stabilize the shape of the absorbent body 20, a carrier sheet (not shown) may be provided under the absorbent body 20 or to completely wrap the absorbent body 20. The substrate of the carrier sheet may be any hydrophilic material, including tissue, absorbent paper, and hydrophilic nonwoven fabrics such as air-laid nonwoven fabrics. When multiple carrier sheets are provided, the substrates of the multiple carrier sheets may be the same or different.

[0030] <Back seat> The backsheet 30 may be formed using a liquid-impermeable substrate that prevents the body fluids retained by the absorbent sheet 20 from wetting the wearer's clothing. Examples of such substrates include resin films and composite sheets that are laminates of resin films and nonwoven fabrics. The nonwoven fabrics used in the composite sheets may be made by any method, and examples include single-layer nonwoven fabrics such as spunbonded nonwoven fabrics and meltblown nonwoven fabrics, composite nonwoven fabrics such as spunbonded nonwoven fabric / meltblown nonwoven fabric laminates, and spunbonded nonwoven fabric / meltblown nonwoven fabric / spunbonded nonwoven fabric laminates, as well as composite materials thereof. Examples of resin films include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0031] The basis weight of the back sheet 30 is, for example, 15 g / m from the viewpoint of strength and processability. 2 More than 60g / m 2The range is as follows. In order to prevent stuffiness during wear, it is preferable that the back sheet 30 be breathable. To make the back sheet 30 breathable, for example, a filler may be blended into the resin film of the base material, or the back sheet 30 may be embossed. An example of the filler is calcium carbonate, and the blending method may be any known method without any restrictions.

[0032] The backsheet 30 has an adhesive layer 80 as an adhesive layer (d) on its non-skin-facing surface. In an embodiment in which a release sheet 71 is provided, the adhesive layer 80 is used to removably adhere the release sheet 71, or to ultimately attach a new product to underwear. The adhesive layer 80 contains an adhesive that exhibits adhesion to resin films, paper, nonwoven fabrics, etc. The adhesive contained in the adhesive layer 80 is not particularly limited, and known adhesives can be used, such as hot melt adhesives. Hot melt adhesives with melting points of 100°C or higher and 180°C or lower can be used without any particular limitation, and examples include synthetic rubber hot melt adhesives such as styrene-butadiene-styrene copolymers and styrene-isoprene-styrene copolymers, and olefin hot melt adhesives such as ethylene-vinyl acetate copolymers. Known methods for applying the hot melt adhesive can be used, such as the curtain coating method or spiral method, in which a molten hot melt adhesive is applied from a nozzle in a non-contact manner, or the slot method, in which a molten hot melt adhesive is applied in a contact manner. The same adhesive may be used for the adhesive layers 80 and 81, or different adhesives may be used for the adhesive layers 80 and 81. Also, double-sided tape or the like may be used instead of the adhesive layers 80 and 81.

[0033] <3D gathers> The three-dimensional gathers 40 may be provided at both widthwise ends of the skin-facing surface of the top sheet 10 so as to extend along the longitudinal direction of the absorbent article 50, for example, in order to prevent side leakage of bodily fluids excreted by the wearer of the absorbent article 50. The three-dimensional gathers 40 include an elastic stretchable member 40a and a water-repellent and / or waterproof sheet member 40b.

[0034] The elastically stretchable member 40a is disposed along the longitudinal direction near the free end (other end) of the sheet member 40b, imparting upstanding property to the free end and allowing the free end and its neighboring area of ​​the sheet member 40b to deform to fit the wearer's body shape. In this embodiment, one widthwise end (fixed end) of the sheet member 40b is fixed to the skin-side surface of the backsheet 30 near both widthwise ends, a middle portion in the widthwise direction is fixed to the skin-side surface of the topsheet 10 near both widthwise ends, and the other widthwise end is a free end that is upstanding. The fixing position of the fixed end (one widthwise end) of the sheet member 40b is not limited to this embodiment, and examples include the non-skin-side surface of the backsheet 30, near both widthwise ends of the skin-side or non-skin-side surface of the joint between the topsheet 10 and the backsheet 30, which has the absorbent body 20 housed therein, and near both widthwise ends of the skin-side surface of the topsheet 10.

[0035] The sheet member 40b is a water-repellent and / or waterproof sheet, and is made of, for example, a nonwoven fabric. The nonwoven fabric for the first sheet member can be any water-repellent and / or waterproof (liquid-impermeable) nonwoven fabric made of hydrophobic fibers, and examples thereof include spunbond nonwoven fabric, meltblown nonwoven fabric, and composite nonwoven fabric (SMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate. The basis weight of the sheet member 40b is, for example, 13 g / m 2 More than 20g / m 2 The range is as follows: As the elastic stretchable member 40a, for example, thread-, string- or band-shaped members made of natural rubber, synthetic rubber, polyurethane or the like can be used as appropriate.

[0036] <Side seat> A pair of side sheets 60 may be provided at both longitudinal ends of the skin-facing surface of the top sheet 10, extending in the width direction of the absorbent article 50. The material for the side sheets 60 can be any liquid-impermeable nonwoven fabric or resin film similar to that used for the back sheet 30, without any particular limitation. The side sheets 60 are provided, for example, so as to cover both longitudinal ends of the top sheet 10 along its shape, with the longitudinal dimensions of one and the other being, for example, in the range of 10 mm to 30 mm.

[0037] <Release sheet> As shown in FIG. 2, the release sheet 71 is releasably adhered to the back sheet 30 by a first release layer 85 interposed between the release sheet 71 and an adhesive layer 80 (adhesive layer (d)). The first release layer 85 is, for example, provided on the surface of the release sheet 71. The release sheet 71 includes, for example, a substrate and a first release layer 85 provided on the entire surface or a portion of the substrate and containing a release agent. A sealing layer (not shown) may also be provided between the substrate and the first release layer 85. Examples of the substrate include paper substrates such as semi-bleached kraft paper, kraft paper, fine paper, medium-quality paper, alkaline paper, glassine paper, semi-glassine paper, paperboard, and white paperboard, as well as various synthetic resin films. Examples of the release agent contained in the first release layer 85 include silicone-based release agents and fluorine-based release agents. The sealing layer is intended to prevent the release agent from penetrating into the paper substrate when the release agent is applied to the paper substrate, and is formed as a thin layer of a few μm to a few tens of μm in thickness made of a thermoplastic resin such as polyester, polyethylene, polypropylene, polyamide, or polyvinyl alcohol. The sealing layer may be a clay coating layer. The release sheet 71 includes a paper substrate, and the paper substrate has higher rigidity than the nonwoven fabric or resin film that constitutes the individual packaging sheet 72, which has the advantage of being easy to peel off from the individual packaging sheet 72.

[0038] In a preferred embodiment, the release sheet 71 is smaller in the longitudinal and width directions than the individual packaging sheet 72 and / or larger in the longitudinal and width directions than the adhesive layer 81 serving as the adhesive layer (e). According to this embodiment, the release sheet 71 can be easily peeled back, simplifying the series of operations of peeling the release sheet 71 to expose the adhesive layer 81 serving as the adhesive layer (e) and attaching the new absorbent article 50 to underwear. The non-skin-facing surface of the release sheet 71 has an adhesive layer 81 as the adhesive layer (e). The adhesive layer 81 has the same structure as the adhesive layer 80 as the adhesive layer (d) described above. The adhesives and / or bonding agents contained in the adhesive layers 80 and 81 may be the same or different.

[0039] <Individually wrapped sheets> As shown in FIG. 2, the individual wrapping sheet 72 is adhered to the release sheet 71 by an adhesive layer 81 serving as an adhesive layer (e). One end of the Z-shaped adhesive tape 70 is fixed to the surface (non-skin-facing surface in this embodiment) of the individual wrapping sheet 72 opposite to the surface (skin-facing surface in this embodiment) that is bonded to the adhesive layer 81. The individual wrapping sheet 72 is made of a resin film, paper, nonwoven fabric, antibacterial nonwoven fabric, or a laminate of two or more of these. By using an antibacterial nonwoven fabric for the individual wrapping sheet 72, the growth of germs is prevented, thereby reducing the generation of odors associated with the growth of germs and enabling the replacement of the absorbent article 50 to be carried out hygienically and safely. In a preferred embodiment, a resin film, paper, or antibacterial nonwoven fabric is used for the individual wrapping sheet 72. From the viewpoints of strength and processability, the basis weight of the individual wrapping sheet 72 is, for example, 15 g / m when it is made of a resin film, nonwoven fabric, or antibacterial nonwoven fabric. 2 More than 50g / m 2 In the case of paper, for example, 30 g / m 2 More than 70g / m 2 The range is as follows:

[0040] Examples of antibacterial nonwoven fabrics include nonwoven fabrics that contain antibacterial fibers with an antibacterial activity of 2.0 or higher as the main component and also contain other fibers, and nonwoven fabrics made of antibacterial fibers with an antibacterial activity of 2.0 or higher. "Containing as the main component" means that the content exceeds 50% by weight of the total. Examples of fibers that can be contained in addition to antibacterial fibers include synthetic fibers made from synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton.

[0041] The antibacterial fiber is not particularly limited as long as it has antibacterial properties, but a fiber obtained by fiberizing a synthetic fiber kneaded with an inorganic antibacterial agent is preferred. As the inorganic antibacterial agent, an inorganic compound containing antibacterial metal ions such as silver, copper, and zinc can be used without particular limitation. For example, metal compounds containing the above-mentioned antibacterial metal ions, zeolites, hydrotalcites, hydroxyapatites, clay minerals, inorganic porous bodies such as alumina, silica, and bentonite can be mentioned. The inorganic antibacterial agent can be used alone or in combination of two or more. The antibacterial fiber can be produced, for example, by adding and kneading one or more inorganic antibacterial agents to a synthetic resin in a molten state and then spinning the synthetic resin. Here, examples of the synthetic resin to which the inorganic antibacterial agent is blended include polyester resins such as polyester and polyethylene terephthalate, polyolefin resins such as polyethylene and polypropylene, polyacrylamide, polyvinyl alcohol, crosslinked polyvinyl alcohol, ethylene vinyl acetate copolymer, and polyvinyl formal. The blending amount of the inorganic antibacterial agent with respect to the synthetic resin is, from the viewpoint of setting the antibacterial activity value within a predetermined range and the strength of the obtained antibacterial fiber, for example, in the range of 0.005% by weight or more and 0.5% by weight or less in the total amount of 100% by weight of the inorganic antibacterial agent and the synthetic resin.

[0042] In this embodiment, an antibacterial test is carried out using Staphylococcus aureus and Escherichia coli in accordance with the JIS L 1902 bacterial liquid absorption method, and a standard cloth (cotton cloth) is used as a control, and an antibacterial fiber having an antibacterial activity value of 2.0 or more is used. Here, the antibacterial activity value is measured according to the bacterial liquid absorption method of JIS L1902.

[0043] <Z-type adhesive tape> As shown in Figures 3 to 8, the Z-shaped adhesive tape 70 has a first fold and a second fold that are spaced apart and extend widthwise from one end of the strip-shaped tape substrate (strip) to the other end in the longitudinal direction, and has a Z-shaped external shape when viewed from the side when folded at these first fold and second fold. The Z-shaped adhesive tape 70 has an area A from one end to the first fold, an area B from the first fold to the second fold, and an area C from the second fold to the other end. Area A has an adhesive layer 75 as an adhesive layer (a) on one surface and is fixed to one surface (in this embodiment, the non-skin-facing surface) of the individual packaging sheet 72 (FIG. 7). Area B has a hook tape 76 as a hook tape (b) on the other surface opposite Area A and is fixed to the skin-facing surface of the top sheet 10 of the used product. Area C has an adhesive layer 77 as an adhesive layer (c) on one surface on the same side as Area A, and is finally sealed and fixed to the package of the used product made of the individual packaging sheet 72. The adhesive layers 75 and 77 have the same structure as the adhesive layer 80 as the adhesive layer (d) described above. A release layer may be formed on the surface of Area C facing the adhesive layer 77 to facilitate unfolding the Z-shaped adhesive tape 70 when folded. Here, the release layer has the same configuration as the aforementioned first release layer 85. The hook tape 76 provided in region B can be, for example, any hook tape that can engage with the skin-facing surface of the topsheet 10, without any particular limitations. The shape and dimensions of the hook tape 76 are selected appropriately depending on the shape and dimensions of region B, but it is usually formed to have a shape and dimensions slightly smaller than those of region B. The hook tape 76 is disposed on a predetermined surface of region B by, for example, spreading with an adhesive, sewing, or other methods. The longitudinal dimensions of regions A, B, and C may be the same or different.

[0044] The position where the Z-shaped adhesive tape 70 is fixed to the individual packaging sheet 72 is not particularly limited. In a preferred embodiment, as shown in FIG. 6, when the Z-shaped adhesive tape 70 is unfolded, the Z-shaped adhesive tape 70 is fixed at a position where the adhesive portion 77 (tab side) of region C is not exposed much or at all (FIG. 8). According to this embodiment, when a used product is wrapped in the individual packaging sheet 72 and rolled up, the adhesive portion 77 is prevented from sticking to a garbage bag or the like. Examples of the strip-shaped tape substrate for the Z-shaped adhesive tape 70 include paper, plastic, cloth, and nonwoven fabric. Among these, a tape substrate made of a plastic film is preferred. The dimensions of the unfolded Z-shaped adhesive tape 70 are not particularly limited and can be selected appropriately depending on the width and length dimensions of the absorbent article 50. The width dimension is, for example, in the range of 100 mm to 500 mm, and the length dimension is, for example, in the range of 400 mm to 2000 mm. Furthermore, to give an example of the dimensions of the Z-shaped adhesive tape 70, when folded, the length dimension of the long side is in the range of 40 mm to 60 mm, and the length dimension of the short side is in the range of 10 mm to 20 mm, and when unfolded, the length dimension of the long side is in the range of 120 mm to 140 mm, and the length dimension of the short side is in the range of 10 mm to 20 mm.
