Description

Technical Field

[0001] The present disclosure relates to a tape-fastened absorbent article.

Background Art

[0002] Due to the increase in the elderly population, the number of care recipients who cannot enter nursing facilities is increasing. For this reason, the number of cases where family members care for care recipients at home is increasing. In the case of assisting with excretion, caregivers who are not used to wearing disposable diapers often change the diapers, and leakage due to improper wearing, as well as the associated increase in the workload of cleaning, washing, etc., has become a social problem.

[0003] For bedridden care recipients, it is common to use a tape-fastened absorbent article as an outer layer and, from the perspectives of economy and absorbency selectivity, use an inner pad in combination inside the tape-fastened absorbent article used as the outer layer. The inner pad is selected based on the wearing time according to the replacement interval and the amount of excretion. A good example is to wear a small urine collection pad during the day and a large wide pad at night. Since the caregiver's activity time is during the day, it is easy to assist in replacing the small inner pad in a relatively short time. However, at night during bedtime, the wearing time is long, and leakage is likely to occur due to multiple urinations and the pad shifting accompanying body position changes. In addition, large inner pads (such as wide pads) that are often worn at night or for a long time are large in size, making it difficult for home caregivers to properly raise the three-dimensional gathers in combination with the tape-fastened absorbent article and place the inner pad in the appropriate position for wearing, which is also one of the reasons likely to lead to leakage.

[0004] Patent Document 1 discloses so-called outer absorbent articles such as a taped panty type using an inner pad or a panty type pre-formed three-dimensionally. In this absorbent article, a recessed portion is provided at the central portion in the width direction of the absorber around the leg portion, and the inner pad is attached to this recessed portion to prevent displacement of the inner pad. Further, by disposing a first elastic body on the flap portions formed on both sides in the width direction of the absorber, the absorber portion around the leg is brought into close contact with the wearer's skin. Further, by disposing a second elastic body disposed along the longitudinal direction between the absorber portion around the leg and the back sheet, the absorber portion around the leg is brought into close contact with the crotch portion of the wearer even when the inner pad is not used.

Embodiments for Carrying out the Invention

[0012] Hereinafter, with reference to the drawings, a tape-fastened absorbent article according to an embodiment of the present invention will be described.

[0013] In this specification, the wearing of the tape-fastened absorbent article means a state in which the tape-fastened absorbent article is attached to the body, regardless of before, during, and after the absorption of body fluids. Also, the "longitudinal direction" of each component member of the tape-fastened absorbent article means the longitudinal direction in the unfolded state of the tape-fastened absorbent article (the state shown in FIG. 1), which is the direction along the arrow X in the figure. Further, the "width direction" of each component member of the tape-fastened absorbent article means the direction that intersects (is orthogonal to) the longitudinal direction in the unfolded state of the tape-fastened absorbent article, which is the direction along the arrow Y in the figure. Also, the "thickness direction" of each component member of the tape-fastened absorbent article means the direction that intersects (is orthogonal to) both the longitudinal direction and the width direction, which is the direction in which each component member is laminated, and is the direction along the arrow Z in the figure. Also, the "front side" means the direction that becomes the abdominal side of the wearer when the tape-fastened absorbent article is worn, and the "rear side" means the direction that becomes the back side of the wearer. Also, the "left-right direction" means the left-right direction as viewed from the wearer in the state facing forward. Also, the "skin side" of each component member of the tape-fastened absorbent article means the direction that faces the wearer's skin among the thickness directions, and the "non-skin side" means the direction opposite to the skin side among the thickness directions. Also, body fluids refer to liquids discharged from the body to the outside, such as urine, blood, and moisture in soft feces.

[0014] <Tape-fastened absorbent article> FIG. 1 is a plan view from the skin side in a deployed state of a tape-fastened absorbent article according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is an explanatory view of the displacement-preventing adhesive portion, where (a) shows a state without a release sheet and (b) shows a state with a release sheet. FIG. 4 is a plan view from the skin side in a deployed state of a tape-fastened absorbent article showing a state where an inner pad is disposed inside. FIG. 5 is a cross-sectional view taken along line V-V of FIG. 4. Note that in FIGS. 2 and 5, a state where the three-dimensional gathers are raised is illustrated. Also, each figure does not define the size relationship of the constituent members of the tape-fastened absorbent article, and the dimensions of each constituent member can be appropriately selected from a wide range according to the use of the tape-fastened absorbent article, the age of the wearer to be used, and the like.

[0015] The tape-fastened absorbent article 10 according to the present embodiment is mainly worn as an outer by disposing an inner pad 100 (see FIGS. 4 and 5) inside. That is, the tape-fastened absorbent article 10 of the present embodiment is a tape-fastened absorbent article 10 (outer) used in combination with the inner pad 100.

[0016] As shown in FIG. 1, the tape-fastened absorbent article 10 continuously includes a front body part 11 positioned on the ventral side of the wearer during wearing, a crotch part 12 positioned at the wearer's thigh, and a back body part 13 positioned on the dorsal side of the wearer in the longitudinal direction. On both sides in the width direction of the back body part 13, there are provided left and right side flaps 14 extending outward in the width direction from the back body part 13, and left and right fastening tapes 15 extending outward in the width direction from the left and right side flaps 14. That is, the tape-fastened absorbent article 10 has fastening tapes 15 on both sides in the width direction of the back body part 13. The fastening tape 15 has a hook member constituting a hook-and-loop fastener. Further, on the non-skin side surface of the front body part 11, fixing means such as a target tape (not shown) to which the fastening tape 15 can be fixed is provided. The target tape has a loop member constituting a hook-and-loop fastener. When wearing the tape-fastened absorbent article 10, the left and right fastening tapes 15 of the back body part 13 are fixed to the target tape of the front body part 11 for wearing. As the base material of the side flap 14, there may be mentioned resin films or non-woven fabrics made of polyethylene, polypropylene, polystyrene, etc., and these base materials may be used alone or in combination of a plurality.

[0017] (Dimensions of the tape-fastened absorbent article) The longitudinal length L1 of the tape-fastened absorbent article 10 is 700 mm or more and 1100 mm or less. The widthwise length W1 of the largest part of the tape-fastened absorbent article 10 is 700 mm or more and 1500 mm or less. By setting the dimensions (longitudinal length L1 and widthwise length W1) of the tape-fastened absorbent article within the above range, the inner pad 100 can be appropriately arranged, and a tape-fastened absorbent article 10 of a size corresponding to the body types of various wearers can be obtained as an outer.

[0018] As shown in FIGS. 1 and 2, the tape-fastened type absorbent article 10 includes a liquid-permeable topsheet 16 disposed on the skin side, a liquid-impermeable backsheet 17 disposed on the non-skin side, an absorber 18 disposed between the topsheet 16 and the backsheet 17, left and right three-dimensional gathers 19 disposed on both sides in the width direction of the skin side surface, and a displacement-preventing adhesive portion 20 provided on the left and right three-dimensional gathers 19. The topsheet 16 and the backsheet 17 of the present embodiment are integrally formed from the buttocks portion 13 through the crotch portion 12 to the buttocks portion 13, and constitute the outer shape of the tape-fastened type absorbent article 10 as a diaper.

[0019] In the present embodiment, the outer shape of the tape-fastened type absorbent article 10 as a diaper is constituted by the topsheet 16 and the backsheet 17, but it is not limited thereto. For example, an outer package constituting the outer shape of the tape-fastened type absorbent article 10 as a diaper may be provided, and an absorbent body constituted by the topsheet 16, the backsheet 17, and the absorber 18 may be fixed to the skin side surface of the crotch portion 12 of the outer package. The outer belt may be constituted by an outer nonwoven fabric sheet described later.

[0020] (Topsheet) The topsheet 16 may be formed from a base material having liquid permeability that allows body fluid to move to the absorber 18. Examples of the base material include nonwoven fabrics such as thermal bond nonwoven fabrics, composite nonwoven fabrics obtained by laminating thermal bond nonwoven fabrics / spunbond nonwoven fabrics, apertured films such as apertured polyethylene films, polyethylene foams, foamed films such as urethane foams, or composite sheets obtained by laminating these. The shape of the topsheet 16 is not particularly limited, but it may be a shape that covers the absorber 18 in order to guide body fluid to the absorber 18 without leakage.

[0021] For the topsheet 16, in order to improve liquid permeability, embossing or perforating may be applied to the surface. As methods for applying these embossing and perforating, known methods can be implemented without limitation. Further, in order to reduce irritation to the skin, the topsheet 16 may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, moisturizer, etc.

[0022] (Backsheet) The backsheet 17 may be formed using a liquid-impermeable base material so that there is no leakage of the body fluid held by the absorber 18 to the non-skin side, and is formed from materials such as a resin film or a composite sheet formed by laminating a resin film and a non-woven fabric. The non-woven fabric used for the composite sheet is not particularly limited in the manufacturing method, and examples include composite non-woven fabrics formed by laminating a plurality of same-kind and / or different-kind non-woven fabrics such as spunbond non-woven fabric, meltblown non-woven fabric, spunbond non-woven fabric / meltblown non-woven fabric, and spunbond non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric, and these composite materials. Examples of the resin film include polyester, polyvinyl alcohol, polyethylene, polypropylene, and a composite film of polyethylene and polypropylene.

[0023] Further, it is preferable to provide the backsheet 17 with air permeability in order to prevent stuffiness during wearing. In order to provide the backsheet 17 with air permeability, for example, a filler may be blended into the resin film of the base material, or the backsheet 17 may be embossed. Examples of the filler include calcium carbonate, and the blending method can be carried out without limitation using known methods. For example, a resin and a filler are kneaded, the obtained kneaded product is formed into a film shape, and the filler is removed from the obtained film to obtain a porous (air-permeable) resin film.

[0024] (Outer non-woven fabric sheet) An exterior nonwoven fabric sheet may be provided on the non-skin side of the backsheet 17. The exterior nonwoven fabric sheet may be composed of a single sheet, or may be a laminate of multiple sheets. As the exterior nonwoven fabric sheet, for example, nonwoven fabrics such as thermal bond nonwoven fabric, air-through nonwoven fabric, and spunbond nonwoven fabric, preferably air-through nonwoven fabric or spunbond nonwoven fabric, made of thermoplastic resins such as polypropylene, polyester, and polyethylene can be used.

[0025] (Absorbent body) The absorbent body 18 is a member that can mainly absorb and hold body fluids, contains a body fluid absorption material, and preferably includes absorbent fibers as a base material and a body fluid absorption material held by the absorbent fibers.

[0026] (Absorbent fibers) The absorbent fibers as the base material of the absorbent body 18 are not particularly limited as long as they are generally used in absorbent articles such as sanitary napkins, diapers, and urine pads. For example, they can be formed from materials such as fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, and hydrophilic nonwoven fabric. Among these, from the perspective of absorbency, it is preferable to use fluff pulp. Examples of fluff pulp include those obtained by defibrating wood pulp, synthetic fibers, polymer fibers, non-wood pulp, etc. into a cotton-like state.

[0027] (Body fluid absorption material) The body fluid absorption material of the absorbent body 18 is not particularly limited as long as it can absorb and hold body fluids. For example, super absorbent polymers (SAP) can be mentioned. Examples of SAP include polyacrylate salts, polyaspartate salts, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers and their saponified products. Among these, from the perspective of the absorption amount per unit weight, polyacrylate salts are preferable, alkali metal polyacrylate salts are more preferable, and sodium polyacrylate is even more preferable. SAP can be used alone or in combination of two or more.

[0028] SAP is used, for example, in the form of particles, fibers, etc., and is preferably used in the form of particles from the viewpoint of ease of handling, etc. At this time, by avoiding the use of fine powder SAP with poor fluidity as a powder and using SAP having a median particle diameter, the basic performance regarding absorption can be enhanced, and the rough tactile sensation generated by the absorber 18 becoming hard can be reduced.

[0029] In the absorber 18, the form of the absorbent fiber and SAP may be one formed by mixing SAP particles in the absorbent fiber, or may be a SAP sheet in which SAP particles are fixed between the absorbent fibers. Further, as another form of the absorber 18, an absorbent sheet including a plurality of hydrophilic nonwoven fabrics and SAP fixed between the hydrophilic nonwoven fabrics can also be used. Further, from the viewpoints of preventing the dropout of SAP particles and stabilizing the shape of the absorber 18, it is preferable to wrap the absorber 18 with a carrier sheet. As the base material of the carrier sheet, any material having hydrophilicity may be used, and examples thereof include hydrophilic nonwoven fabrics such as tissue, absorbent paper, and airlaid nonwoven fabric. When the absorber 18 includes a plurality of carrier sheets, the base materials of the carrier sheets may be the same or different.

[0030] The absorber 18 extends in the longitudinal direction from the front waist part 11 through the crotch part 12 to the back waist part 13. The absorber 18 of the present embodiment is formed in an hourglass shape in which the front waist part 11 and the back waist part 13 are longer in the width direction than the crotch part 12. Note that the shape of the absorber 18 is not limited to the hourglass shape, and may be, for example, a rectangular shape or the like.

[0031] The length W2 in the width direction of the maximum part of the absorber 18 in the back hip part 13 is 300 mm or more and 500 mm or less. By setting the length W2 in the width direction of the absorber 18 within the above range, inner pads 100 of various sizes used in combination can be appropriately arranged. Also, the wearing feeling can be moderately maintained as the outer part. Further, when body fluid leaks from the inner pad 100, the wide absorber 18 in the back hip part 13 of the outer (tape-fastened absorbent article 10) can receive and absorb the body fluid.

[0032] (Three-dimensional gathers) The left and right three-dimensional gathers 19 are members provided to prevent lateral leakage of body fluid excreted by the wearer, and are arranged on both sides in the width direction of the skin side surface of the tape-fastened absorbent article 10, and extend longitudinally from the front hip part 11 through the crotch part 12 to the back hip part 13. The left and right three-dimensional gathers 19 of the present embodiment include a water-repellent and / or waterproof gather sheet 19a and an elastic stretch member 19b. Since the left and right three-dimensional gathers 19 are provided symmetrically with respect to the tape-fastened absorbent article 10, hereinafter, only one of them will be described and the description of the other will be omitted.

[0033] The gather sheet 19a is a sheet having water-repellent and / or waterproof properties, and is composed of, for example, a non-woven fabric. As the non-woven fabric for the gather sheet 19a, a water-repellent and / or waterproof (liquid-impermeable) non-woven fabric formed of hydrophobic fibers can be used without particular limitation, and examples thereof include a spunbond non-woven fabric, a meltblown non-woven fabric, and a composite non-woven fabric (SMS non-woven fabric) which is a spunbond non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric laminate.

[0034] The gathered sheet 19a is disposed on both sides of the skin side of the tape-fastened absorbent article 10 in the width direction, and extends in the longitudinal direction from the front body section 11 through the crotch section 12 to the rear body section 13. The outer region 21 of the gathered sheet 19a in the width direction is fixed to the outer region of the skin side of the tape-fastened absorbent article 10 in the width direction. The gathered sheet 19a is fixed by a method such as a hot melt adhesive or heat fusion. In this embodiment, the outer region 21 of the gathered sheet 19a in the width direction is formed so as to protrude outward in the width direction from the top sheet 16, and the outer end portion in the width direction protruding outward in the width direction from the top sheet 16 is fixed to the back sheet 17, and the middle portion in the width direction is fixed to the top sheet 16 (see FIG. 2). The fixed position of the gathered sheet 19a is not limited to the above, and it is sufficient that the gathered sheet 19a is fixed at least to the outer region in the width direction of the skin side of the tape-fastened absorbent article 10.

[0035] Both longitudinal ends (parts indicated by diagonal lines in FIG. 1) of the inner region 22 of the gather sheet 19a in the width direction are fixed to the top sheet 16 (the sheet facing the gather sheet 19a) and function as end seal parts 23. The longitudinal middle part (region 24 between the end seal parts 23 on both sides in the longitudinal direction) of the inner region 22 of the gather sheet 19a in the width direction is an upstanding region 24 that is not fixed to the top sheet 16, and has the essential function of three-dimensional gathers 19. In other words, the region 24 between the end seal parts 23 of the gather sheet 19a has a root part 24a on the outer side in the width direction that is fixed to the top sheet 16, and a tip part (free end) 24b on the inner side in the width direction, and functions as three-dimensional gathers 19.

[0036] The elastic stretchable member 19b is disposed along the longitudinal direction near the inner end (free end) 24b in the width direction of the gathered sheet 19a, and imparts stretchability and standing ability to the free end, enabling the end (free end) 24b of the three-dimensional gathers 19 and its neighboring area to be deformed to fit the wearer's body shape. As the elastic stretchable member 19b, for example, a thread-, string- or band-shaped member made of natural rubber, synthetic rubber, polyurethane, or the like can be appropriately used.

[0037] (Dimensions of the three-dimensional gathers on the left and right) When the three-dimensional gathers 19 on the left and right are erected, the widthwise interval W3 between the base portions 24a is 180 mm or more and 270 mm or less. A space 25 (hereinafter referred to as the "inner pad storage space 25") where the inner pad 100 can be disposed is defined between the three-dimensional gathers 19 on the left and right in the erected state. That is, the length in the width direction of the inner pad storage space 25 is 180 mm or more and 270 mm or less. If the widthwise interval W3 between the base portions 24a of the three-dimensional gathers 19 on the left and right is made narrower than 180 mm, it becomes difficult to store the inner pad 100 (especially a large-sized wide pad) in the inner pad storage space 25. On the other hand, if the widthwise interval W3 between the base portions 24a of the three-dimensional gathers 19 on the left and right is made wider than 270 mm, the length in the width direction of the crotch portion 12 of the tape-fastened absorbent article 10 also becomes longer, so the wearing feeling deteriorates. Also, an excessive margin is created in the space (inner pad storage space 25) where the inner pad 100 fits, and there is a risk that leakage may easily occur due to the inner pad 100 shifting.

[0038] The length W4 in the width direction from the base portion 24a to the tip portion 24b of the three-dimensional gathers 19 on the left and right is 60 mm or more and 85 mm or less. That is, when the three-dimensional gathers 19 on the left and right are erected, the height is 60 mm or more and 85 mm or less. If the length W4 from the base portion 24a to the tip portion 24b of the three-dimensional gathers 19 on the left and right is made shorter than 60 mm, there is a risk that the holding property when storing the inner pad 100 and the height of the barrier when urine leakage occurs will be insufficient. On the other hand, if the length W4 from the base portion 24a to the tip portion 24b of the three-dimensional gathers 19 on the left and right is made longer than 85 mm, the length becomes excessive for the function, and it becomes difficult to adhere at an appropriate position around the legs, so there is a risk that body fluid leakage may easily occur and the wearing feeling also deteriorates. Also, since the length becomes excessive for the function, there is a risk that the manufacturing cost (material cost) will increase.

[0039] The longitudinal length L2 of the left and right three-dimensional gathers 19 is 400 mm or more and 800 mm or less. That is, the longitudinal length of the inner pad storage space 25 is 400 mm or more and 800 mm or less. If the longitudinal length L2 of the left and right three-dimensional gathers 19 is made shorter than 400 mm, it becomes difficult to store the inner pad 100 (especially a large wide pad) in the inner pad storage space 25. On the other hand, if the longitudinal length L2 of the left and right three-dimensional gathers 19 is made longer than 800 mm, there will be a surplus in the space (inner pad storage space 25) for holding the inner pad 100 in an appropriate position, and the inner pad 100 may shift and body fluid leakage may easily occur.

[0040] (Displacement prevention adhesive part) As shown in FIGS. 1 to 3, the displacement prevention adhesive part 20 is a part that functions as a displacement prevention for the inner pad 100 (see FIGS. 4 and 5) arranged in the inner pad storage space 25, and is provided on the inner side surface in the width direction of the left and right three-dimensional gathers 19 in the standing state. The displacement prevention adhesive part 20 of the present embodiment is provided at one location on each side (two locations in total on both the left and right sides) on the inner side surface in the width direction at the central part in the longitudinal direction of the left and right three-dimensional gathers 19. Note that the displacement prevention adhesive part 20 of the present embodiment is formed in a rectangular shape, but the shape of the displacement prevention adhesive part 20 is not limited to this.

[0041] The adhesive for forming the displacement prevention adhesive part 20 is not particularly limited. For example, hot melt adhesives such as polyacrylate, vinyl acetate-ethylene copolymer, vinyl acetate-acrylic copolymer, polymethyl methacrylate, polystyrene, styrene-acrylic copolymer, polyester resin, epoxy resin, styrene-butadiene-styrene block copolymer (SBS), styrene block copolymer (SBC), styrene-styrene-isoprene block copolymer (SIS), and styrene-ethylene-butylene-styrene block copolymer (SEBS) can be mentioned. These may be used alone or in a blend of multiple types.

[0042] (Dimensions of the displacement prevention adhesive part) As shown in FIG. 3(a), the length L3 in the longitudinal direction of the misalignment prevention adhesive portion 20 is 20 mm or more and 45 mm or less. Also, the length W5 in the width direction of the misalignment prevention adhesive portion 20 is 10 mm or more and 30 mm or less. By setting the dimensions of the misalignment prevention adhesive portion 20 within the above range, it will not be overly large during the wearing operation when used in combination with the inner pad 100, and it is difficult to induce incorrect operations such as adhering to unintended locations. Also, by setting the dimensions of the misalignment prevention adhesive portion 20 within the above range, as will be described later, when the left and right three-dimensional gathers 19 of the tape-fastened absorbent article 10 and the three-dimensional gathers 104 of the inner pad 100 (see FIG. 5) are adhered, sufficient adhesiveness can be ensured to assist the standing properties of the three-dimensional gathers 19, 104 in cooperation.

[0043] The misalignment prevention adhesive portion 20 may be colored in a color different from the color of the gather sheet 19a (for example, white), such as light blue, green, etc. By coloring the misalignment prevention adhesive portion 20 in a color different from the color of the gather sheet 19a, the visibility of the misalignment prevention adhesive portion 20 can be improved, and the workability when wearing the inner pad 100 can be improved.

[0044] (Release sheet) As shown in FIG. 3(b), the tape-fastened absorbent article 10 may include a peelable release sheet 26 for protecting the misalignment prevention adhesive portion 20 when the misalignment prevention adhesive portion 20 is not used. The release sheet 26 is adhesively bonded to the misalignment prevention adhesive portion 20 in a peelable manner while covering the misalignment prevention adhesive portion 20. The release sheet 26 is composed of a film such as polyethylene, a non-woven fabric such as spunbond, SMS (spunbond non-woven fabric / meltblown non-woven fabric / spunbond non-woven fabric), or a composite member of a film and a non-woven fabric. By configuring the release sheet 26 with the above materials, it is possible to prevent the deterioration of the skin contact due to the release sheet 26 when wearing the tape-fastened absorbent article 10 without using the misalignment prevention adhesive portion 20, which is different from the case of using silicone paper, for example. Note that the release sheet 26 may not be provided.

[0045] The release sheet 26 may be colored in a color different from the color of the gather sheet 19a (for example, white), such as light blue, green, etc. By coloring the release sheet 26 in a color different from the color of the gather sheet 19a, the visibility of the release sheet 26 can be improved, and the workability when wearing the inner pad 100 can be improved.

[0046] (Usage) Next, the case where the tape-fastened absorbent article 10 is used in combination with the inner pad will be described.

[0047] As shown in FIGS. 4 and 5, a large inner pad 100 (such as a wide pad) used in combination with the tape-fastened absorbent article 10 includes, for example, a liquid-permeable top sheet 101, a liquid-impermeable back sheet 102, an absorber 103 disposed between the top sheet 101 and the back sheet 102, and left and right three-dimensional gathers 104. Also, a small inner pad (such as a urine collection pad) (not shown) has substantially the same configuration as the above-described large inner pad 100, except for different shapes and sizes. The base materials constituting the top sheet, back sheet, absorber, and left and right three-dimensional gathers of the inner pad may be substantially the same as the top sheet 16, back sheet 17, absorber 18, and left and right three-dimensional gathers 19 of the above-described tape-fastened absorbent article 10, although their shapes and sizes are different.

[0048] As shown in FIGS. 4 and 5, when using the large inner pad 100 for nighttime or long-term use in combination, first, the inner pad 100 is placed in the inner pad storage space 25 (see FIGS. 1 and 2) of the tape-fastened absorbent article 10. Next, the release sheet 26 is peeled off to expose the anti-displacement adhesive portion 20, and the anti-displacement adhesive portion 20 is adhered to the inner pad 100. At this time, it is preferable to adhere the anti-displacement adhesive portion 20 of the left and right three-dimensional gathers 19 of the tape-fastened absorbent article 10 to the three-dimensional gathers 104 of the inner pad 100 with the three-dimensional gathers 104 of the inner pad 100 standing up.

[0049] Also, when using a small inner pad in combination with, for example, during the day, the inner pad may be placed and used in the inner pad storage space 25 of the tape-fastened absorbent article 10 without using the displacement-preventing adhesive portion 20. In this case, the tape-fastened absorbent article 10 and the small inner pad may be worn with the displacement-preventing adhesive portion 20 covered with the release sheet 26.

[0050] As described above, when wearing a small inner pad (urine pad), since its size is small and the wearing operation is relatively simple, and it is used during a time period with a high replacement frequency (for example, during the day), it is preferable not to use the displacement-preventing adhesive portion 20. On the other hand, when wearing a large inner pad 100 (wide pad) for a long time at night or the like, it is preferable to use the displacement-preventing adhesive portion 20.

[0051] In the tape-fastened absorbent article 10 configured as described above, since the displacement-preventing adhesive portion 20 is provided on the inner surfaces in the width direction of the left and right three-dimensional gathers 19 in the standing state, when wearing a large inner pad 100 for a long time at night or the like, the displacement-preventing adhesive portions 20 of the left and right three-dimensional gathers 19 can function as a displacement prevention for the inner pad 100. Therefore, even when there are multiple urinations or the wearer changes body posture during long-term use at night or the like, displacement and sway of the inner pad 100 can be suppressed, and body fluid leakage can be prevented.

[0052] Also, since it is provided with the displacement-preventing adhesive portion 20, a caregiver can easily place a large inner pad 100, which has a large size, at an appropriate position of the tape-fastened absorbent article 10 and easily let a wearer such as a care recipient wear it.

[0053] In addition, since the displacement prevention adhesive portion 20 is provided on the inner surface in the width direction of the left and right three-dimensional gathers 19, the left and right three-dimensional gathers 19 can be adhered to the three-dimensional gathers 104 of the inner pad 100 as described above. Therefore, due to the interaction between the left and right three-dimensional gathers 19 of the tape-fastened absorbent article 10 and the three-dimensional gathers 104 of the inner pad 100, the three-dimensional gathers 19, 104 can be stably held in an upright state. As a result, even a caregiver who is not used to wearing the inner pad 100 or the tape-fastened absorbent article 10 can easily put the tape-fastened absorbent article 10 on the appropriate position of the care recipient, so that body fluid leakage during long-term use can be reduced.

[0054] Therefore, according to the present embodiment, the work load of the caregiver can be reduced.

[0055] In addition, by providing the displacement prevention adhesive portion 20 at the central portion in the longitudinal direction of the left and right three-dimensional gathers 19, the position where the displacement prevention adhesive portion 20 exists can be easily recognized as the central portion in the longitudinal direction of the inner pad storage space 25. For this reason, since the large inner pad 100 can be easily positioned at the appropriate front-rear position of the tape-fastened absorbent article 10, the number of do-overs is reduced even in the replacement work of the inner pad accompanied by the weight movement of the care recipient, and the work load of the caregiver can be further reduced.

[0056] As described above, the present invention has been described based on the above embodiment, but the present invention is not limited to the content of the above embodiment, and can be appropriately changed without departing from the scope of the present invention. That is, of course, all other embodiments, examples, operation techniques, etc. made by those skilled in the art based on this embodiment are included in the scope of the present invention.
