DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (1) Overview of the embodiment At least the following points will become apparent from the description of this specification and the accompanying drawings. The invention according to the first aspect is an exterior body of an absorbent article. The exterior body of the absorbent article includes an absorbent article having a top sheet that contacts the skin of a wearer and a back sheet to which a fastening part that fastens to a worn article is attached, and an exterior sheet that is disposed on the non-skin side of the absorbent article and to which the fastening part is fastened. The absorbent article before use is folded with the skin side of the absorbent article on the inside, with an article fold line along the width direction as a base point. In the folded absorbent article folded with the article fold line as a base point, the mutually facing surfaces of the absorbent article are temporarily joined by a temporary joint. When at least one of the absorbent article and the exterior sheet is pulled by a user, the exterior sheet and the absorbent article are separated. The user pulls the absorbent article in the folded state to separate the exterior sheet and the absorbent article. In the folded absorbent article, the mutually facing surfaces of the absorbent article are temporarily joined by a temporary joint. Therefore, when the absorbent article and the outer sheet are separated, the absorbent article can be moved with the temporarily joined area integrated. The temporarily joined area is more rigid and less likely to twist than a state where it is not temporarily joined because it is integrated. Therefore, it is possible to prevent the absorbent article from twisting when the outer sheet and the absorbent article are separated, and to prevent the fastening part from fastening to an unintended place before the absorbent article is used, and to prevent a defect in which the absorbent article cannot be used before use. In addition, the temporarily joined area has a high rigidity, and when a force is applied to pull the absorbent article, the force is easily transmitted. Therefore, the provision of the temporarily joined area allows the absorbent article to be smoothly separated from the outer sheet. In addition, when the absorbent article and the outer sheet are separated, the rigidity of the absorbent article side is increased due to the presence of the temporarily joined area. When the outer sheet is peeled off, by increasing the rigidity of the absorbent article, which is the other side to be peeled off, it is easier to continue to apply the peeling force, and the separation operation can be performed smoothly.

[0010] According to a preferred embodiment, the invention according to embodiment 2 may have the following features in the invention according to embodiment 1. The absorbent article is attached to the worn article in an unfolded state where it is not folded along the article crease. When the absorbent article is separated from the outer sheet, it is in a folded state and temporarily joined by a temporary joint. Therefore, the absorbent article can be separated from the outer sheet while suppressing twisting of the absorbent article. And, since the absorbent article is attached to the worn article in an unfolded state, it is possible to suppress the absorbent articles from overlapping with each other and the discomfort caused by the temporary joint when wearing the absorbent article.

[0011] According to a preferred embodiment, the invention according to embodiment 3 may have the following features in the invention according to embodiment 1 or embodiment 2. The shear strength of the temporary joint is higher than the peel strength of the fastening part and the outer sheet in a 180° peel test. According to this embodiment, since the shear strength of the temporary joint is higher than the peel strength of the fastening part and the outer sheet in a 180° peel test, the bonded state of the temporary joint can be maintained when the fastening part and the outer sheet are peeled off at 180°, and the absorbent article and the outer sheet can be separated while still bonded by the temporary joint.

[0012] According to a preferred embodiment, the invention according to embodiment 4 may have the following features in the invention according to embodiment 3. The temporary joint has a higher peel strength than the peel strength of the fastening part and the outer sheet in a 90° peel test. According to this embodiment, since the shear strength of the temporary joint is higher than the peel strength of the fastening part and the outer sheet in a 90° peel test, the bonded state of the temporary joint can be maintained when the fastening part and the outer sheet are peeled off at 90°, and the absorbent article and the outer sheet can be separated while still bonded by the temporary joint.

[0013] According to a preferred embodiment, the invention according to embodiment 5 may have the following features in the invention according to any one of embodiments 1 to 4. The temporary joint joins the top sheets together. According to this embodiment, the top sheets that come into contact with the wearer's skin are temporarily joined together, so that fingers are less likely to get between the top sheets when removing the absorbent article, and the absorbent article can be removed hygienically without touching the top sheets.

[0014] According to a preferred embodiment, the invention according to embodiment 6 may have the following features in the invention according to any one of embodiments 1 to 5. The temporary joint joins opposing surfaces of the absorbent article with an adhesive. The adhesive is configured so as not to rejoin after being peeled off once. According to this embodiment, the temporary joint functions when separating the absorbent article from the outer sheet, and does not function once the absorbent article is unfolded, thereby preventing the adhesive from coming into contact with the skin when worn, and reducing discomfort when worn.

[0015] According to a preferred embodiment, the invention according to embodiment 7 may have the following features in the invention according to any one of embodiments 1 to 6. The absorbent article has a second sheet that contacts the non-skin surface of the top sheet. The temporary joint joins the opposing surfaces of the absorbent article with an adhesive. The adhesive joins the top sheets to each other and also joins the top sheet and the second sheet. The shear force between the top sheets is lower than the shear force between the top sheet and the second sheet. According to this embodiment, the surfaces where the top sheets face each other can be unfolded when the absorbent article is used while maintaining the joined state between the top sheet and the second sheet. This can suppress the problem of the top sheet and the second sheet peeling off, and suppress deterioration of product quality.

[0016] According to a preferred embodiment, the invention according to embodiment 8 may have the following features in the invention according to any one of embodiments 1 to 5. The temporary joint is formed by pressing the surfaces of the absorbent article together. According to this embodiment, the temporary joint is formed by pressing, and the density of the part where the temporary joint is formed is increased, and the rigidity is also increased. Therefore, it is possible to further suppress twisting of the absorbent article when separating the absorbent article and the outer sheet. Furthermore, compared to a temporary joint made of an adhesive, no adhesive remains on the surface where the temporary joint is provided, so that it is possible to suppress a sense of incongruity or discomfort when it touches the skin.

[0017] According to a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to any one of embodiments 1 to 5. The temporary joint is formed by fusing fibers arranged on opposing surfaces of the absorbent article. According to this embodiment, the temporary joint is formed by fusing fibers, so that the density of the part where the temporary joint is formed is increased and the rigidity is also increased. Therefore, it is possible to further suppress twisting of the absorbent article when separating the absorbent article from the outer sheet. Furthermore, compared to a temporary joint formed by adhesive, no adhesive remains on the surface where the temporary joint is provided, so that it is possible to suppress a sense of incongruity or discomfort when touching the skin. An example of the joining by fusing fibers can be heat welding.

[0018] According to a preferred embodiment, the invention according to embodiment 10 may have the following features in the invention according to any one of embodiments 1 to 9. In the folded state, the area of ​​the bonded regions where the temporary bonded parts are provided on the mutually facing surfaces of the absorbent article is smaller than the area of ​​the non-bonded regions where the temporary bonded parts are not provided on the mutually facing surfaces of the absorbent article. According to this embodiment, since the area of ​​the bonded regions where the temporary bonded parts are provided is relatively small, the bond strength of the temporary bonded parts is prevented from becoming too strong, and the absorbent article can be smoothly unfolded when unfolding the absorbent article in the folded state.

[0019] According to a preferred embodiment, the invention according to embodiment 11 may have the following features in the invention according to any one of embodiments 1 to 9. In the folded state, the area of ​​the bonded regions where the temporary bonded parts are provided on the mutually facing surfaces of the absorbent articles is larger than the area of ​​the non-bonded regions where the temporary bonded parts are not provided on the mutually facing surfaces of the absorbent articles. According to this embodiment, since the area of ​​the bonded regions where the temporary bonded parts are provided is relatively large, the bond strength of the temporary bonded parts can be increased, and the temporary bonded state can be easily maintained when the absorbent article and the exterior sheet are separated.

[0020] According to a preferred embodiment, the invention according to embodiment 12 may have the following features in the invention according to any one of embodiments 1 to 11. The absorbent article in the folded state is folded in half around the article fold. The exterior body has a packaging sheet that individually packages the absorbent article before use and is configured to allow the absorbent article to be taken out through an outlet when used. The outlet is configured to be provided at an end opposite to the article fold in the front-rear direction. In the folded state, the front end edge of the absorbent article and the rear end edge of the absorbent article are offset in the front-rear direction. When a user tries to pull out the absorbent article from the outlet, the user grasps the front end and the rear end of the absorbent article. At this time, since the front end edge of the absorbent article and the rear end edge of the absorbent article are offset, one of the front end edge and the rear end edge of the absorbent article protrudes, making it easier for the user to grasp the end of the absorbent article and improving operability when pulling out the absorbent article.

[0021] According to a preferred embodiment, the invention according to embodiment 13 may have the following features in the invention according to any one of embodiments 1 to 12. The absorbent article has an absorbent layer disposed between the top sheet and the back sheet. In the folded state, the absorbent layer is disposed only in the area where the surfaces of the absorbent article overlap each other facing each other. According to this embodiment, the absorbent layer is disposed only in the area where the surfaces of the absorbent article overlap each other facing each other, and is not disposed in the area extending from the facing surfaces. The area extending from the facing surfaces is an area that is easy for a user to grasp when removing the absorbent article. Since the absorbent layer is not disposed in the area extending from the facing surfaces, it is difficult for a user to grasp the absorbent layer when removing the absorbent article, and the problem that the absorbent layer is soiled or crushed when removing the absorbent layer can be suppressed. In addition, if the fastening parts self-adhere to each other in the area where the absorbent layer is disposed before use, and the area where the absorbent layer is disposed becomes twisted, the absorbent layer cannot be applied appropriately to the wearer, and the absorption performance cannot be ensured. However, since the absorbent layer is disposed in the area where the absorbent articles overlap, it is possible to prevent the area where the absorbent layer is disposed from twisting when the outer cover sheet and the absorbent articles are separated, thereby ensuring absorption performance.

[0022] According to a preferred embodiment, the invention according to embodiment 14 may have the following features in the invention according to any one of embodiments 1 to 13. The absorbent article in the folded state is configured to move to the removal side along the front-rear direction relative to the exterior sheet and separate from the exterior sheet. The temporary joint is provided on the removal side relative to the center in the front-rear direction of the opposing faces of the absorbent article. The region on the removal side relative to the center in the front-rear direction of the opposing faces of the absorbent article is located on the tip side in the direction in which the absorbent article moves, and is an area that is easily grasped by the user. Since the temporary joint is provided in the region on the removal side relative to the center in the front-rear direction of the opposing faces, when a user grasps the absorbent article from the removal side, it is difficult for the user's fingers to get between the opposing faces of the absorbent article, and the absorbent article can be removed hygienically.

[0023] According to a preferred embodiment, the invention according to embodiment 15 may have the following features in the invention according to any one of embodiments 1 to 14. The absorbent article in the folded state is configured to move to the removal side along the front-rear direction relative to the exterior sheet and separate from the exterior sheet. The temporary joint is disposed on the removal side relative to the tip of the fastening part on the removal side. When the exterior sheet and the absorbent article are separated, separation starts from the tip of the fastening part on the removal side. Because the temporary joint is provided on the removal side relative to the tip of the fastening part on the removal side, the absorbent article can be removed while suppressing deformation of the absorbent article when force is applied to the tip of the fastening part.

[0024] According to a preferred embodiment, the invention according to embodiment 16 may have the following features in the invention according to any one of embodiments 1 to 14. The absorbent article in the folded state is configured to move to a removal side along the front-rear direction with respect to the outer sheet and to be separated from the outer sheet. The fastening parts extend in the width direction and are provided in a plurality of parts at intervals in the front-rear direction. The temporary joining parts are provided in the regions between the fastening parts in the front-rear direction and in the regions overlapping with the fastening parts. According to this embodiment, since the fastening parts are arranged at intervals in the front-rear direction, when the outer sheet and the absorbent article are separated, the regions overlapping with the fastening parts are pulled, and the regions between the fastening parts are not fastened to the worn article and are therefore easily deformed. In the process of separating the outer sheet and the absorbent article, the regions overlapping with the fastening parts are pulled and the regions between the fastening parts are repeatedly deformed, and the fastening parts are likely to self-attach. However, since temporary joints are provided in both the areas between the fastening parts and the areas overlapping with the fastening parts, deformation of the absorbent article during the process of separating the outer sheet and the absorbent article can be suppressed, and the problem of the fastening parts fastening in unintended locations can be suppressed.

[0025] According to a preferred embodiment, the invention according to embodiment 17 may have the following features in the invention according to any one of embodiments 1 to 16. The absorbent article in the folded state is configured to move to the removal side along the front-rear direction relative to the outer sheet and to be separated from the outer sheet. The absorbent article has an inspection member for inspecting the health condition of a wearer. The temporary joint is disposed on the removal side relative to the tip of the inspection member on the removal side. According to this embodiment, since the temporary joint is disposed on the removal side relative to the inspection member, the rigidity of the area where the inspection member is disposed can be increased, and deformation of the inspection member when the absorbent article is separated from the outer sheet can be suppressed.

[0026] The invention according to the eighteenth aspect is a method for manufacturing an outer body of an absorbent article. The method for manufacturing the outer body is a method for manufacturing an outer body of an absorbent article having an absorbent article having a top sheet that contacts the skin of a wearer and a back sheet to which a fastening part that fastens to a worn article is attached, and an outer sheet that is disposed on the non-skin side of the absorbent article and to which the fastening part is attached. The manufacturing method includes an adhesive applying step of applying an adhesive to the non-skin side surface of the top sheet, a folding step of folding the absorbent article so that the top sheets face each other after the adhesive applying step, and a temporary joining step of pressing the absorbent article folded by the folding step and temporarily joining the top sheets to each other with the adhesive that has passed through the top sheet. According to this aspect, a temporary joining part that joins the top sheets to each other can be provided. Therefore, when the absorbent article and the outer sheet are separated, the absorbent article can be moved with the temporarily joined area integrated, and the absorbent article can be prevented from twisting when the outer sheet and the absorbent article are separated.

[0027] (2) Exterior body of absorbent article according to the first embodiment Hereinafter, the exterior body (hereinafter referred to as the exterior body) 1 of the absorbent article of the first embodiment will be described with reference to the drawings.

In addition, in the cross-sectional views, the components are shown separated for the sake of convenience, but in the actual product, the components are in contact with each other.

[0028] FIG. 1 is a diagram showing a folded state of the exterior body 1 according to the first embodiment. FIG. 1(a) is a plan view, and FIG. 1(b) is a schematic cross-sectional view along the line AA shown in FIG. 1(a). FIG. 2 is a plan view of the exterior body 1 in an unfolded state, as viewed from the skin side T1. FIG. 3 is a cross-sectional view along the line BB shown in FIG. 2. The exterior body 1 has a front-rear direction L and a width direction W that are mutually perpendicular and extend in a planar direction, and a thickness direction T. The front-rear direction L is along the front-rear direction L of the absorbent article 10. In the front-rear direction L of the absorbent article, the side that contacts the lower abdomen of the user is called the "front side", and the side that contacts the buttocks of the user is called the "rear side". The thickness direction T extends to the skin side T1 and the non-skin side T2. The "skin side" corresponds to the side that faces the skin of the wearer during use. The "non-skin side" corresponds to the side that faces away from the skin of the wearer during use.

[0029] Here, the outer part in the present invention is a part that occupies a certain range in the width direction W including the outer edge in the width direction W, and the outer edge is the outer edge in the width direction W. The outer edge of a component that occupies a certain range in the front-rear direction is an edge that connects points located on the outside in the width direction of the component over the entire component. The inner part in the present invention is a part that occupies a certain range in the width direction W including the inner edge in the width direction W, and the inner edge is the inner edge in the width direction W.

In addition, the front end and rear end in the present invention are parts that occupy a certain range in the front-rear direction L including edges in the front-rear direction L, and the front end edge and rear end edge are edges in the front-rear direction L. The outer end includes the front end and rear end, and the outer end edge includes the front end edge and rear end edge. In addition, the inner side is a side that includes the inner edge and extends along the front-rear direction L. The outer side is a side that includes the outer edge and extends along the front-to-rear direction L. In this specification, the term "along the front-to-rear direction L" means a direction having an angle of less than 45° with respect to the front-to-rear direction L, and the term "along the width direction W" means a direction having an angle of less than 45° with respect to the width direction W.

[0030] The exterior body 1 has at least an absorbent article 10 and an exterior sheet 20 arranged on the non-skin side T2 of the absorbent article 10. The absorbent article 10 may be any article that is attached to a worn article such as underwear and used, and may be an absorbent article such as a sanitary napkin, a panty liner, an incontinence pad, or a feces pad. The absorbent article 10 of the first embodiment is a panty liner that is attached to a worn article and used.

[0031] The absorbent article 10 may have at least a top sheet 11, a back sheet 12, and an absorbent layer 13. The top sheet 11 is a sheet that contacts the wearer's skin. The top sheet 11 constitutes the skin side T1 of the absorbent article 10. The top sheet 11 may be a liquid-permeable sheet, and may be made of any sheet-like material having a liquid-permeable structure, such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, or a mesh sheet. The top sheet 11 of this embodiment is made of a single sheet arranged over the entire area of ​​the absorbent article 10 in a planar view. However, in another embodiment, the top sheet 11 may have a center sheet arranged at the center of the width direction W of the absorbent article 10, and a side sheet covering the outer side of the center sheet.

[0032] The back sheet 12 constitutes the non-skin side T2 of the absorbent article 10 and is a sheet that comes into contact with the worn article. The back sheet 12 is provided with a fastening part 15 for fastening to the worn article. The back sheet 12 may be a liquid-impermeable sheet, and may be a polyethylene sheet, a laminated nonwoven fabric mainly made of polypropylene or the like, a breathable resin film, or a sheet in which a breathable resin film is bonded to a nonwoven fabric such as spunbond or spunlace.

[0033] The fastening portion 15 is disposed on the non-skin surface of the backsheet 12, and is an area provided with fastening means (e.g., an adhesive) for fastening the absorbent article 10 to a worn article such as underwear. The fastening portion 15 in this embodiment extends in the width direction W, and a plurality of fastening portions 15 are provided at intervals in the front-rear direction L. Note that in a modified example, the fastening portion 15 may extend in the front-rear direction L, and a plurality of fastening portions 15 may be provided at intervals in the width direction W. The fastening portion 15 may be fastening means disposed in an area overlapping with the absorbent layer 13.

[0034] The absorbent layer 13 is a layer containing an absorbent material, and may be disposed on the skin side T1 of the back sheet 12. The absorbent layer 13 may be a nonwoven fabric containing cellulose fibers, or a laminate in which pulp is laminated. The laminate may contain a superabsorbent polymer (SAP) together with pulp. When the absorbent layer 13 is formed of a nonwoven fabric, the surface of the skin side T1 of the absorbent layer 13 may be disposed so as to abut against the wearer. That is, the absorbent layer 13 may constitute the top sheet 11. An example of an absorbent article of this type is a configuration having a skin-facing nonwoven fabric containing cotton fibers, an air-through nonwoven fabric disposed on the non-skin side T2 of the skin-facing nonwoven fabric, and a back sheet 12 disposed on the non-skin side T2 of the air-through nonwoven fabric. The skin-facing nonwoven fabric constitutes the top sheet 11 and the absorbent layer 13, and the air-through nonwoven fabric constitutes the second sheet 14. In addition, whether the absorbent layer 13 is formed of a laminate containing pulp or a nonwoven fabric containing cellulose fibers, the absorbent article 10 may have a core wrap sheet covering the absorbent layer 13. The core wrap sheet may be formed of, for example, a nonwoven fabric or tissue. The absorbent article of this embodiment has at least a top sheet 11, an absorbent layer 13 made of an airlaid pulp sheet, and a back sheet 12, but does not have a core wrap sheet. In addition, the absorbent layer 13 may reach the outer edge of the absorbent article in a plan view.

[0035] The absorbent article 10 may have a second sheet 14 that contacts the non-skin surface of the top sheet 11. The second sheet 14 may be disposed between the top sheet 11 and the absorbent layer 13. The second sheet 14 may be a liquid-impermeable sheet, and may be made of, for example, a nonwoven fabric. In a modified example, the absorbent article 10 may not have the second sheet 14.

[0036] The exterior body 1 may have a packaging sheet 21. The packaging sheet 21 is a sheet that individually packages the absorbent article 10. The packaging sheet 21 may be made of a nonwoven fabric or a film. In order to ensure the sealing of the exterior body 1, the packaging sheet 21 preferably has low breathability and may be made of a film. In the unfolded state, the packaging sheet 21 may have a rectangular shape and a pair of front and rear side edges 211 extending along the front-rear direction L and spaced apart in the width direction W, and a pair of width side edges 212 extending along the width direction W and spaced apart in the front-rear direction L. The front and rear side edges 211 constitute the outer edges of the packaging sheet 21, and the width side edges 212 constitute the outer end edges of the packaging sheet 21. In a state where the packaging sheet 21 is folded around a packaging crease FL21 described later as a base point, the pair of width side edges 212 are arranged to overlap, and the overlapped width side edges 212 constitute the sides facing the packaging crease FL21.

[0037] The exterior body 1 may have a release sheet 22 disposed between the absorbent article 10 and the packaging sheet 21. The release sheet 22 may be a sheet that has been subjected to a release treatment. The release sheet 22 may have a paper substrate and a release agent applied to the substrate. The release agent may be one that can reduce the coefficient of friction of the sheet surface, and examples of the release agent include silicone-based resins, fluorine-based resins, and tetrafluoroethylene-based resins.

[0038] The exterior body 1 has an exterior sheet 20. The exterior sheet 20 is a sheet to which the fastening parts 15, which are arranged in an area overlapping with the absorbent layer 13, are attached. In a configuration in which the fastening parts 15 abut against the packaging sheet 21, the packaging sheet 21 constitutes the exterior sheet 20. In a configuration in which a release sheet 22 is arranged between the packaging sheet 21 and the absorbent article 10 and the fastening parts 15 abut against the release sheet 22 as in this embodiment, the release sheet 22 constitutes the exterior sheet. That is, in this embodiment, the release sheet 22 constitutes the exterior sheet 20.

[0039] The packaging sheet 21 and the release sheet 22 may be joined in a joining region 25. A plurality of joining regions 25 may be provided at intervals in the front-rear direction L. The joining region 25 in this embodiment has a first joining region 251 overlapping the front end of the release sheet 22 and a second joining region 252 overlapping the rear end of the release sheet 22. The first joining region 251 and the second joining region 252 may be located on both sides of a packaging fold FL21 and a peeling fold FL22 described later in the front-rear direction L. A non-joint region may be provided continuously between the first joining region 251 and the second joining region 252. Regions other than the first joining region 251 and the second joining region 252 are non-joint regions where the packaging sheet 21 and the release sheet 22 are not joined. The non-bonded area includes not only the area between the first bonding area 251 and the second bonding area 252, but also the area in front of the first bonding area 251, the area behind the second bonding area 252, and the area outside the bonding area 25 in the width direction W.

[0040] Before use, the exterior body 1 individually packages the absorbent articles 10 with the packaging sheet 21. The absorbent articles 10 may be folded together with the packaging sheet 21 and individually packaged with the packaging sheet 21, or, in a form having a release sheet 22, the release sheet 22 may also be folded together. Also, as in Modification 2, the packaging sheet may be arranged to package the absorbent articles that have been folded in advance, i.e., the folds of the absorbent articles and the folds of the packaging sheet may be provided in separate processes.

[0041] In this embodiment, the packaging sheet 21 is folded about a packaging crease FL21, and the release sheet 22 is folded about a peeling crease FL22. The packaging crease FL21 may be located near the center in the front-rear direction L of the packaging sheet 21 in the unfolded state, and the peeling crease FL22 may be located near the center in the front-rear direction L of the release sheet 22 in the unfolded state. The packaging sheet 21 has a substantially rectangular shape surrounded by four sides when folded about the packaging crease FL21, and three of the four sides other than the side formed by the packaging crease FL21 are provided with packaging joints where overlapping packaging sheets 21 are joined to each other. The packaging joint has a first packaging joint 231 that joins an area extending inward in the front-rear direction L from the width side edge 212, a second packaging joint 232 that joins an area extending inward in the width direction W from the front-rear side edge 211 located on one side of the center in the width direction W of the packaging sheet 21, and a third packaging joint 233 that joins an area extending inward in the width direction W from the front-rear side edge 211 located on the other side of the center in the width direction W of the packaging sheet 21. The width of the packaging joint can be set as appropriate, but is preferably 5 mm or more to ensure airtightness.

[0042] The packaging joints can be formed by a known method such as welding or adhesive. One end of the second packaging joint 232 may be connected to the first packaging joint 231, and the other end of the second packaging joint 232 may be connected to the packaging crease FL21. One end of the third packaging joint 233 may be connected to the first packaging joint 231, and the other end of the third packaging joint 233 may be connected to the packaging crease FL21. By providing the packaging joints in this manner, the exterior body 1 is in a sealed state. In the packaged state, the exterior body 1 has a packaging space WS that can accommodate the absorbent article 10. The packaging space WS is a space sandwiched between the inner surfaces of the packaging sheet 21, and is surrounded by the packaging crease FL21, the first packaging joint 231, the second packaging joint 232, and the third packaging joint 233 in a plan view.

[0043] In the packaged state, the package sheet 21 is formed with a cut line 27 for forming a take-out opening 5 (see FIG. 4) for taking out the absorbent article 10. The package sheet 21 is configured to individually package the absorbent article 10 before use and to allow the absorbent article 10 to be taken out through the take-out opening 5 when used. In the present embodiment, the cut line 27 extends from the front and rear side edges 211 toward the inside in the width direction W. The cut line 27 is formed in an area where the first package joint 231 and the second package joint 232 are provided. The user cuts the package sheet 21 using the cut line 27 as a base point, whereby at least one of the first package joint 231 and the second package joint 232 is cut, the package space WS is opened, and the take-out opening 5 is formed. The take-out opening 5 may be provided at an end of the exterior body 1 in the front-rear direction L in the packaged state, opposite to the article fold FL10. This allows the user, when removing the absorbent article 10, to grasp the front end or rear end of the absorbent article 10, which is the side opposite the article fold FL10, and remove the absorbent article 10.

[0044] The absorbent article 10 before use is folded with the skin side T1 of the absorbent article 10 facing inward, with the article fold FL10 along the width direction W as the base point. In this embodiment, in a state in which the packaging sheet 21, the release sheet 22, and the absorbent article 10 are stacked, the absorbent article 10, the packaging sheet 21, and the release sheet 22 are all folded in half with the fold along the width direction W as the base point. Thus, the packaging fold FL21, the article fold FL10, and the release fold FL22 are formed simultaneously and overlap each other. In a modified example, the article fold FL10 may be a fold in which only the absorbent article 10 is folded, and the packaging sheet 21 and the release sheet 22 are not folded together. The article fold FL10 may be disposed in the center of the absorbent article 10 in the front-rear direction L.

[0045] The article fold FL10 is a fold along the width direction W along which the absorbent article 10 is folded before use. The absorbent article 10 before use may be folded only around the article fold FL10 as a base point, or may be folded along a fold other than the article fold FL10. The fold other than the article fold FL10 is a fold that does not run along the width direction W, for example, a fold along the front-to-rear direction along which the wings are folded.

[0046] When using the absorbent article 10, the user pulls at least one of the absorbent article 10 and the exterior sheet 20 to separate the absorbent article 10 from the exterior sheet 20. The exterior body 1 of the present embodiment is configured to suppress problems that occur when the fastening part 15 of the absorbent article 10 is peeled off from the exterior sheet 20 to separate the absorbent article 10 and the exterior sheet 20. Next, the configuration for suppressing problems that occur when the absorbent article 10 and the exterior sheet 20 are separated will be described in detail.

[0047] In the absorbent article 10 in a folded state, folded around an article fold line FL10, opposing surfaces of the absorbent article 10 are temporarily joined by a temporary joint 18. When at least one of the absorbent article 10 and the exterior sheet 20 is pulled by a user, the exterior sheet 20 and the absorbent article 10 are separated. The absorbent article 10 is configured to be separated from the exterior sheet 20 while joined by the temporary joint 18. A front-to-rear range R10 of the opposing surfaces of the absorbent article 10 in a folded state is shown in FIG.

[0048] The absorbent article 10 in the folded state may be in a state where it is folded at at least one article fold line FL10, and in a form having a plurality of article fold lines FL10, it may be in a state where some of the article fold lines are used as base points and other article fold lines are not used as base points. That is, in a form having a plurality of article fold lines, the absorbent article 10 may be provided with a temporary joint 18 and the absorbent article 10 and the exterior sheet 20 may be separated in a state where some of the article fold lines are used as base points and other article fold lines are not used as base points, or the absorbent article 10 may be provided with a temporary joint 18 and the absorbent article 10 and the exterior sheet 20 may be separated in a state where all of the article fold lines are used as base points. In a form having one article fold line FL10 as in the present embodiment, the absorbent article 10 may be provided with a temporary joint 18 and the absorbent article 10 and the exterior sheet 20 may be separated in a state where it is folded with the one article fold line FL10 as base point.

[0049] The absorbent article 10 in the folded state may have a first region where the surfaces of the absorbent articles facing each other are arranged, and a second region extending from the first region. The first region is a region where the absorbent articles 10 are stacked in the thickness direction T, and the second region is a region where the absorbent articles 10 are not stacked in the thickness direction T, and one layer of the absorbent article 10 is arranged. The absorbent article 10 of the present embodiment is folded in half, and the entire area of ​​the absorbent article 10 in the folded state may be the first region, and the second region may not be provided. Alternatively, the front end edge and the rear end edge of the absorbent article may be misaligned, and almost the entire area of ​​the absorbent article 10 (e.g., 90% or more) may be the first region, and a small amount of the second region (e.g., less than 10%) may be provided.

[0050] The absorbent article 10 in the folded state moves to the take-out side D1 (see FIG. 4) along the front-rear direction L relative to the exterior sheet 20, and separates from the exterior sheet 20. The manner in which the absorbent article 10 moves to the take-out side D1 relative to the exterior sheet 20 includes a concept in which the absorbent article 10 is pulled to move to the take-out side D1, and a concept in which the exterior sheet 20 is pulled to the side D2 opposite the take-out side, and the absorbent article 10 moves relatively toward the take-out side D1. In this embodiment, the take-out side D1 is the side of the take-out opening 5, and the side D2 opposite the take-out side is the side of the article fold FL10.

[0051] In the absorbent article 10, in a folded state, opposing surfaces are temporarily joined via temporary joints 18. The configuration in which opposing surfaces are joined may be such that the top sheets 11 are joined to each other when the top sheets 11 face each other as in the present embodiment, or such that the top sheet 11 and the back sheet 12 are joined to each other when the top sheet 11 and the back sheet 12 face each other as in the third embodiment.

[0052] The absorbent article 10 is configured to be separated from the exterior sheet 20 in a folded state, that is, in a state where the absorbent article 10 is temporarily joined by the temporary joining portion 18. FIG. 4 is a diagram showing an example of a separation mode of the absorbent article 10. When a user takes out the absorbent article 10 from the exterior body 1, the user cuts a part of the packaging sheet 21 in the packaged state to form a removal opening 5. FIG. 4(a) shows a state where the removal opening 5 is formed. The user inserts a finger or the like through the removal opening 5, grasps the absorbent article 10, and pulls the absorbent article 10 out of the packaging space WS. FIG. 4(b) shows a state where a part of the absorbent article (an end in the front-rear direction L) is pulled, and a part of the fastening portion 15 is separated from the release sheet 22. When the user further pulls the absorbent article 10, the absorbent article 10 is taken out of the packaging space WS, and the entire fastening portion 15 is separated from the release sheet 22, as shown in FIG. 4(c).

[0053] A user separates the absorbent article 10 from the exterior sheet 20 by pulling the absorbent article 10 in a folded state. In the absorbent article 10 in a folded state, the surfaces facing each other of the absorbent article are temporarily joined by the temporary joining portion 18. Therefore, when the absorbent article 10 and the exterior sheet 20 are separated, the absorbent article 10 can be moved with the temporarily joined area integrated. The temporarily joined area is more rigid and less likely to twist than a state where it is not temporarily joined because it is integrated. Therefore, the absorbent article 10 is prevented from twisting when the exterior sheet 20 and the absorbent article 10 are separated, and the fastening portion 15 is prevented from fastening to an unintended place before the absorbent article 10 is used, and the inconvenience of the absorbent article 10 being in a state where it cannot be used before use can be prevented.

[0054] Furthermore, the temporarily joined regions have a high rigidity, and when a force is applied to pull the absorbent article 10, the force is easily transmitted. Thus, the provision of the temporarily joined regions allows the absorbent article 10 to be smoothly separated from the exterior sheet 20. In addition, when the absorbent article 10 and the exterior sheet 20 are separated, the rigidity of the absorbent article 10 side is increased due to the presence of the temporarily joined regions. When peeling off the exterior sheet 20, by increasing the rigidity of the absorbent article 10, which is the other side to be peeled off, it becomes easier to continue to apply a peeling force, and the separation operation can be performed smoothly.

[0055] The temporary joining portion 18 may be temporarily joined when the absorbent article 10 and the exterior sheet 20 start to be separated (in a folded state before at least one of them is pulled), and the temporary joining may be released when the separation starts, for example, when a part of the fastening portion 15 is separated from the exterior sheet. However, preferably, the temporary joining portion 18 may be joined until the entire fastening portion 15 is separated from the exterior sheet 20. That is, the exterior sheet 20 and the absorbent article 10 may be separated in a state where the joining of the first region R1 (the region where the absorbent article is laminated) is maintained by the temporary joining portion 18. This configuration can suppress twisting of the absorbent article from the start of separation of the exterior sheet 20 and the absorbent article 10 to the completion of separation, and can further suppress self-adhesion of the fastening portion 15.

[0056] The absorbent article 10 may be configured to be attached to a worn article in an unfolded state where it is not folded along the article fold line FL10. That is, the absorbent article 10 may be configured to be attached to a worn article in a state where the temporary joining by the temporary joining portion 18 is released. When the absorbent article 10 is separated from the exterior sheet 20, the absorbent article 10 is in a folded state and temporarily joined by the temporary joining portion 18. Thus, the absorbent article 10 can be separated from the exterior sheet 20 while suppressing the absorbent article 10 from twisting. Since the absorbent article 10 is attached to a worn article in an unfolded state, it is possible to suppress the absorbent articles 10 from overlapping with each other and the discomfort caused by the temporary joining portion 18 when worn. Note that the unfolded state may be a state where the absorbent article 10 is not folded along any of the article fold lines FL10, and may be folded along a fold line other than the article fold line FL10 (for example, a fold line for folding a wing).

[0057] 4(b), when the absorbent article 10 is pulled against the exterior sheet 20, the exterior sheet 20 first peels off at a peel angle of 90° relative to the fastening part 15, and as the peeling progresses, it peels off at a peel angle of 180° relative to the fastening part 15. Furthermore, since both surfaces of the absorbent article 10 that sandwich the temporary joint 18 move in the same pulling direction, a shear force parallel to the opposing surfaces is generated in the temporary joint 18. The shear force parallel to the opposing surfaces is a shear force generated when the surfaces joined by the temporary joint 18 are pulled in opposite directions.

[0058] The shear strength of the temporary joint 18 may be 0.03 N or more and 10.0 N or less. By having a shear strength of the temporary joint 18 of 0.03 N or more, the temporary joint 18 is easily maintained in a bonded state when the absorbent article 10 and the exterior sheet 20 are separated. In addition, by having a shear strength of the temporary joint 18 of 10.0 N or less, the temporary joint 18 is separated with a constant force (10.0 N or less), so that, for example, when a strong force is applied, the bond of the temporary joint 18 is maintained, and thus defects such as the absorbent body being twisted can be suppressed. In addition, the peel strength of the temporary joint 18 in a 180° peel test may be 0.01 N or more and 2.0 N or less. By having a peel strength of the temporary joint 18 in a 180° peel test of 0.01 N or more, the absorbent article can be suppressed from unintentionally unfolding when the absorbent article is taken out, etc. Furthermore, since the peel strength of the temporary joint 18 in a 180° peel test is 2.0 N or less, the opposing surfaces of the absorbent article 10 can be easily peeled away from each other during use, allowing the absorbent article to be unfolded.

[0059] The shear force of the temporary joint 18 may be higher than the peel force in a 180° peel test between the fastening part 15 and the exterior sheet 20. Because the shear force is higher than the peel force in a 180° peel test between the fastening part 15 and the exterior sheet 20, the bonded state of the temporary joint 18 can be maintained when the fastening part 15 and the exterior sheet 20 are peeled off at 180°, and the absorbent article 10 and the exterior sheet 20 can be separated while still bonded by the temporary joint 18.

[0060] Preferably, the shear force of the temporary joint 18 may be higher than the peel force in a 90° peel test between the fastening part 15 and the exterior sheet 20. When peeling between the exterior sheet 20 and the absorbent article 10 begins, the angle between the movement direction of the exterior sheet 20 and the movement direction of the fastening part 15 is 90°. Because the peel force in the 90° peel test between the fastening part 15 and the exterior sheet 20 is lower than the shear force, the bonded state of the temporary joint 18 can be maintained when the fastening part 15 and the exterior sheet 20 are peeled at 90°, and the absorbent article 10 and the exterior sheet 20 can be separated while still bonded by the temporary joint 18.

[0061] The peel strength of the 90° peel test and the 180° peel test of the fastening part 15 and the exterior sheet 20 were measured using an autograph tester (AG-X10plus) manufactured by Shimadzu Corporation. Specifically, first, the exterior body of the sample to be measured is opened so that the holding state of the fastening part and the exterior sheet does not change, and a sample is prepared. The sample is set in the autograph tester, and the peel strength at a pulling speed of 100 mm / min is measured. At this time, the sample is set so that the angle between the exterior sheet and the sample is 90 degrees and 180 degrees in the pulling direction. In addition, in the case of 90-degree evaluation, the target sample is fixed at 90 degrees and evaluated. The peel direction is the main direction when the fastening part is removed from the exterior sheet, and the result is the average value of n=5. (Unit: N / mm (mm is the total width direction length of the fastening part)).

[0062] The shear force of the temporary joint 18 is measured by removing a sample absorbent article from the exterior sheet 20 without affecting the temporary joint 18, (1) cutting the article along the folding line with a sharp cutter or the like to one side and the other side (cutting is also performed so as not to affect the temporary joint and the measurement point). (2) In the case of an absorbent article having a side sheet, in order to eliminate the effect of friction of the side sheet, the part corresponding to the side sheet is cut with a cutter to prepare a sample. (3) Of the surfaces facing each other across the cut point, the edge of the cut point side of one surface of the absorbent article and the edge of the other surface of the absorbent article opposite the cut point are clamped in a chuck, and the shear force is measured at a pulling speed of 100 mm / min (N / mm (mm is the width direction length of the cut absorbent article)). The result is the average of n=5.

[0063] The peel strength of the 180° peel test of the temporary joint 18 was measured using an autograph tester (AG-X10plus) manufactured by Shimadzu Corporation. Specifically, first, the absorbent article to be used as a sample was removed from the exterior sheet 20 so as not to affect the temporary joint 18, and the sample was prepared. The sample was set in the autograph tester, and the peel strength was measured at a pulling speed of 100 mm / min. At this time, the sample was set so that the angle between the opposing surfaces was 180 degrees in the pulling direction. The peel direction was the main direction when one surface was turned over relative to the other opposing surface, and the results were the average of n=5. (Unit: N / mm (mm is the length of the absorbent article in the width direction)).

[0064] The temporary joints 18 may join the top sheets 11 together. The configuration in which the top sheets 11 are joined together by the temporary joints 18 may be such that only the top sheets 11 facing each other are joined by the temporary joints 18, or other components (e.g., the second sheet 14) overlapping the top sheets 11 in the thickness direction T may also be joined together with the top sheets 11. By joining the top sheets 11 together by the temporary joints 18, it is difficult for fingers to get between the top sheets 11 when removing the absorbent article 10, and the absorbent article 10 can be removed hygienically without touching the top sheets 11. In a configuration in which the top sheets 11 are joined together by the temporary joints 18, the top sheets 11 may be provided with a convex portion that protrudes in the thickness direction and a concave portion that is concave in the thickness direction. The convex portion and the concave portion formed on the opposing surfaces engage with each other to increase the frictional force between the top sheets 11, making it easier to maintain the joined state by the temporary joints 18.

[0065] The temporary joint 18 may be used to join the opposing surfaces of the absorbent article 10 with an adhesive. An example of the adhesive is a hot melt adhesive. The adhesive may be configured so as not to rejoin after being peeled off. According to this embodiment, the temporary joint functions when the absorbent article 10 and the exterior sheet 20 are separated, and the temporary joint 18 does not function after the absorbent article 10 is unfolded, so that the adhesive is prevented from touching the skin when worn, and discomfort when worn can be suppressed. Here, an example of an adhesive that does not rejoin after being peeled off is an olefin-based hot melt adhesive. In addition, the concept of an adhesive that does not rejoin includes not only a configuration in which the joining force after being peeled off is 0 N, but also a configuration in which the shear force in a tensile test when joined after being peeled off is 0.01 N or less. In this embodiment, the temporary joint 18 is formed by an adhesive HMA (see Figure 3) that joins the top sheet 11 and the second sheet 14, and more specifically, the temporary joint 18 is formed by the adhesive HMA penetrating the top sheet 11 and seeping out onto the skin-facing surface of the top sheet 11.

[0066] The adhesive constituting the temporary joint 18 may join the top sheets 11 facing each other in the folded state, and may also join the top sheet 11 and the second sheet 14. The shear force between the top sheets 11 may be lower than the shear force between the top sheet 11 and the second sheet 14. According to this embodiment, the surfaces where the top sheets 11 face each other can be unfolded when the absorbent article 10 is used, while maintaining the joined state between the top sheet 11 and the second sheet 14. This can suppress the problem of the top sheet 11 and the second sheet 14 peeling off, and suppress deterioration of product quality. For example, the structure for making the joining strength between the top sheets 11 higher than the joining strength between the top sheet and the second sheet may be such that the basis weight of the adhesive between the top sheet 11 and the second sheet 14 is higher than the basis weight of the adhesive between the top sheets 11.

[0067] The temporary joint 18 is not limited to a configuration in which the surfaces of the absorbent article are joined by adhesive. For example, the temporary joint 18 may be joined by pressure bonding the surfaces of the absorbent article. By forming the temporary joint 18 by pressure bonding, the density of the part where the temporary joint 18 is formed is increased, and the rigidity is also increased. Therefore, the absorbent article 10 can be more prevented from twisting when the absorbent article 10 and the exterior sheet 20 are separated. Furthermore, compared with the temporary joint 18 by adhesive, no adhesive remains on the surface where the temporary joint 18 is provided, so that the sense of incongruity and discomfort when touching the skin can be suppressed. The pressure bonding can be formed, for example, by pressing the non-skin side surface of the absorbent article inward in the thickness direction while the skin side surfaces of the absorbent article are facing each other, and embossing can be exemplified. Note that it is preferable that the fibers of the joined part of the temporary joint by pressure bonding are not fused. Since the fibers of the joined part are not fused, the gap between the fibers is secured, and the transfer and diffusion of bodily fluids can be secured.

[0068] The temporary joints 18 may be formed by fusing fibers arranged on opposing surfaces of the absorbent article 10 together. By forming the temporary joints 18 by fusing fibers, the density of the portion where the temporary joints 18 are formed increases, and the rigidity of the portion also increases. This makes it possible to further suppress twisting of the absorbent article 10 when separating the absorbent article 10 from the exterior sheet 20. Furthermore, compared to the temporary joints 18 formed by adhesive, no adhesive remains on the surface where the temporary joints 18 are formed, so that it is possible to suppress a sense of incongruity or discomfort when touching the skin. An example of joining by fusing fibers is heat welding.

[0069] The area of ​​the bonded region where the temporary bond 18 is provided on the mutually facing surfaces of the absorbent article 10 may be smaller than the area of ​​the non-bonded region where the temporary bond 18 is not provided on the mutually facing surfaces of the absorbent article. The mutually facing surfaces of the absorbent article 10 correspond to the first region. Since the area of ​​the bonded region where the temporary bond 18 is provided on the mutually facing surfaces of the absorbent article is relatively small, the bond strength of the temporary bond is prevented from becoming too strong, and the mutually facing surfaces are prevented from breaking when the folded absorbent article is unfolded, and the absorbent article 10 can be easily and smoothly unfolded without applying a strong force. The temporary bond 18 may be provided along the outer edge of the mutually facing surfaces of the absorbent article 10, or may be provided over the entire area of ​​the outer edge of the mutually facing surfaces of the absorbent article 10. The temporary bond 18 may be provided at least on the outer edge that is the tip of the removal side among the outer edges of the mutually facing surfaces of the absorbent article 10.

[0070] In another embodiment, the area of ​​the bonded region where the temporary bonded parts 18 are provided on the opposing surfaces of the absorbent article 10 may be larger than the area of ​​the non-bonded region where the temporary bonded parts 18 are not provided on the opposing surfaces of the absorbent article. Since the area of ​​the bonded region where the temporary bonded parts 18 are provided is relatively large, the bond strength of the temporary bonded parts 18 can be increased, and the temporary bonded state can be easily maintained when the absorbent article and the outer sheet are separated. The bonded region may be at least one of a region where the adhesive constituting the temporary bonded part is applied, a region where a pressed part is formed, and a region where fibers are fused.

[0071] As shown in Figs. 1 and 4, the absorbent article 10 is individually wrapped in a packaging sheet 21 and is configured to be pulled out through an outlet 5 when in use. The outlet 5 is provided at an end opposite to the article fold FL10 in the front-rear direction L. In the folded state, the front end edge of the absorbent article 10 and the rear end edge of the absorbent article 10 may be offset in the front-rear direction L. When a user attempts to pull out the absorbent article 10 from the outlet 5, the user grasps the front end and the rear end of the absorbent article 10. At this time, since the front end edge of the absorbent article and the rear end edge of the absorbent article are offset, one of the front end edge and the rear end edge of the absorbent article protrudes, making it easier for the user to grasp the end of the absorbent article, and improving operability when pulling out the absorbent article 10.

[0072] The length of the shift between the front end edge and the rear end edge of the absorbent article 10 in the front-rear direction may be preferably 3 mm or more, more preferably 5 mm or more. By having such a shift length, the user can easily grasp the protruding portion of one of the front end edge and the rear end edge of the absorbent article 10. Furthermore, the length of the shift between the front end edge and the rear end edge of the absorbent article 10 in the front-rear direction may be preferably 15 mm or less, more preferably 10 mm or less. By having such a shift length, it is possible to grasp the protruding side of one of the front end edge and the rear end edge of the absorbent article 10 as well as the other non-protruding side, and both the front end edge and the rear end edge of the absorbent article 10 can be pulled out together while maintaining the temporary joint state. The temporary joint portion 18 may be provided at the tip of the other non-protruding side on the removal side. According to this configuration, it is easy to pull out the other non-protruding side as well.

[0073] In the folded state, the absorbent layer 13 is disposed only in the area where the surfaces of the absorbent article 10 face each other. That is, the absorbent layer 13 is disposed in the first area, but not in the second area. The absorbent layer 13 is disposed only in the area where the surfaces of the absorbent article 10 face each other, but not in the area extending from the facing surface. The area extending from the facing surface is an area that is easy for the user to grasp when removing the absorbent article 10. Since the absorbent layer 13 is not disposed in the area extending from the facing surface, it is difficult for the user to grasp the absorbent layer 13 when removing the absorbent article 10, and the problem that the absorbent layer 13 becomes dirty or crushed when removed can be suppressed. In addition, if the fastening parts 15 self-adhere to each other in the area where the absorbent layer 13 is disposed before use, and the area where the absorbent layer 13 is disposed becomes twisted, the absorbent layer 13 cannot be applied appropriately to the wearer, and the absorption performance cannot be ensured. However, since the absorbent layer 13 is arranged in the first region where the absorbent articles 10 overlap each other, the region where the absorbent layer 13 is arranged is prevented from wrinkling when the outer sheet 20 and the absorbent articles 10 are separated, and absorption performance can be ensured.

[0074] The temporary joint 18 may be provided on the removal side D1 from the center R10C in the front-rear direction L of the opposing faces of the absorbent article 10. That is, the temporary joint 18 is disposed on the removal side D1 (the removal opening 5 side) from the center in the front-rear direction L of the first region. The region on the removal side D1 from the center R10C in the front-rear direction of the opposing faces of the absorbent article 10 is located on the tip side in the direction in which the absorbent article 10 moves, and is an area that is easily grasped by the user. Since the temporary joint 18 is provided in the region on the removal side D1 from the center in the front-rear direction L of the opposing faces, when a user grasps the absorbent article 10 from the removal side D1, it is difficult for the user to get his / her fingers between the opposing faces of the absorbent article 10, and the absorbent article 10 can be hygienically removed. In addition, it is sufficient that at least a part of the temporary joint 18 is located on the removal side D1 rather than the center R10C in the front-to-back direction of the opposing surfaces of the absorbent article 10, and at least a part of the temporary joint 18 may be located on the opposite side D2 rather than the center R10C in the front-to-back direction of the opposing surfaces of the absorbent article.

[0075] The temporary joint 18 may be disposed on the removal side D1 rather than the tip of the fastening part 15 on the removal side D1. That is, the tip of the temporary joint 18 on the removal side D1 is closer to the removal outlet 5 than the tip of the fastening part 15 on the removal side. When the outer sheet 20 and the absorbent article 10 are separated, they start to separate from the tip of the fastening part 15 on the removal side D1. Since the temporary joint 18 is provided on the removal side D1 rather than the tip of the fastening part 15 on the removal side D1, deformation of the absorbent article 10 when a force is applied to the tip of the fastening part 15 is suppressed, and the absorbent article can be removed while suppressing deformation. Note that it is sufficient that at least a part of the temporary joint 18 is provided on the removal side D1 rather than the tip of the fastening part 15 on the removal side D1, and at least a part of the temporary joint 18 may also be provided on the opposite side D2 rather than the tip of the fastening part 15 on the removal side D1.

[0076] The temporary joining parts 18 may be provided in the regions between the fastening parts 15 in the front-rear direction L and in the regions overlapping with the fastening parts 15. The fastening parts 15 are arranged at intervals in the front-rear direction L. Therefore, when the outer sheet 20 and the absorbent article are separated, the regions overlapping with the fastening parts 15 are pulled, and the regions between the fastening parts 15 are not fastened to the worn article and are therefore easily deformed. In the process of separating the outer sheet 20 and the absorbent article 10, the regions overlapping with the fastening parts 15 are repeatedly pulled and the regions between the fastening parts 15 are deformed, and the fastening parts 15 are likely to self-attach. However, since the temporary joining parts 18 are provided in both the regions between the fastening parts 15 and the regions overlapping with the fastening parts 15, deformation of the absorbent article 10 in the process of separating the outer sheet 20 and the absorbent article 10 can be suppressed, and the fastening parts 15 can be prevented from fastening to unintended locations. Preferably, the temporary joint 18 may be disposed across a region between the fastening parts 15 in the front-rear direction L and a region overlapping with the fastening parts 15 .

[0077] The temporary joint 18 may be disposed in an area overlapping with the absorbent layer 13. Preferably, the temporary joint 18 may reach the outer edge (outer edge and outer end edge) of the absorbent layer 13. In the present embodiment, the outer edge of the absorbent layer 13 coincides with the outer edge of the absorbent article 10, and the temporary joint 18 is also disposed at the outer edge of the absorbent article. With this configuration, the absorbent article 10 and the exterior sheet 20 can be separated while suppressing twisting in the area where the absorbent layer 13 is disposed. In addition, the temporary joint 18 may be disposed on both sides of the center of the width direction W of the absorbent article 10. The absorbent article 10 and the exterior sheet 20 can be separated in a state where the absorbent article 10 is temporarily joined by the temporary joint 18 over a wide range in the width direction of the absorbent article. In addition, the temporary joint 18 may be provided at the outer end edge of the removal side D1 of the absorbent article 10 in the folded state. The outer edge of the removal side D1 of the absorbent article 10 is a portion that is easy for a user to grasp, and can prevent twisting of this portion. The temporary joint 18 of this embodiment is provided over the entire area of ​​the opposing surfaces.

[0078] The exterior body 1 of the present embodiment is configured so that the absorbent article 10 is separated from the packaging sheet 21 while the packaging joint of the packaging sheet 21 is maintained. However, in another embodiment, the packaging joint may be configured so that the joint is released when the absorbent article 10 is separated from the packaging sheet 21. In the other embodiment, the joint strength of the packaging joint may be lower than the shear force of the temporary joint 18. According to this configuration, the packaging joint of the packaging sheet 21 can be partially separated while maintaining the temporary joint by the temporary joint 18, and the absorbent article 10 can be smoothly taken out. Also, in a modified example, the joint strength of the packaging joint may be higher than the shear force of the temporary joint 18. According to this configuration, the joint state of the packaging joint is easily maintained, and after the absorbent article 10 is taken out, a space surrounded by the packaging joint is maintained in the packaging sheet, and the absorbent article 10 can be stored in the space after use, and the absorbent article 10 can be hygienically disposed of. The joint strength of the packaging joint can be measured, for example, by the following method. In the state where separation of the absorbent article 10 and the exterior sheet 20 starts (folded state before at least one of them is pulled), one side packaging sheet and the other side packaging sheet joined by the packaging joint are clamped in an Instron chuck and pulled at a speed of 100 mm / min, and the maximum strength is defined as the joint strength. In this embodiment, the state where separation of the absorbent article 10 and the exterior sheet 20 starts is the state where the take-out opening 5 is formed and the left and right packaging joints are joined, as shown in Figure 4(a).

[0079] The joining area 25 for joining the packaging sheet 21 and the release sheet 22 may be provided in an area that does not overlap the packaging crease FL21 and the peeling crease FL22. If the joining area 25 is provided so as to overlap the packaging crease FL21 and the peeling crease FL22, as shown in FIG. 4, the release sheet 22 does not separate from the packaging crease FL21 when the absorbent article 10 is taken out, and the fastening part 15 is difficult to peel off from the release sheet. However, since the joining area 25 is provided in an area that does not overlap the packaging crease FL21 and the peeling crease FL22, the release sheet 22 is easily lifted from the packaging crease FL21 when the absorbent article 10 is taken out, and the fastening part 15 is easily peeled off from the release sheet. In addition, in a form in which the fastening part 15 abuts against the packaging sheet 21 (a form without a peeling sheet), the fastening part 15 may be provided in an area that does not overlap the packaging crease FL21. With this configuration, the fastening part 15 is easily peeled off from the packaging sheet. Furthermore, the exterior body 1 may have a release sheet 22 against which the fastening part 15 abuts, and may not have a packaging sheet 21. According to this embodiment, the absorbent article 10 can be used by peeling off the release sheet 22 as the exterior sheet 20, and the operation of separating the absorbent article 10 and the exterior sheet 20 can be performed more easily.

[0080] (3) Exterior body of absorbent article according to another embodiment Next, an exterior body of an absorbent article according to another embodiment will be described in detail. In the following description, the same components as those in the first embodiment will be denoted by the same reference numerals and will not be described. With reference to FIG. 5, an exterior body 1X of an absorbent article 10X according to a second embodiment will be described. FIG. 5 is a diagram showing a folded state of the exterior body 1X according to the second embodiment. FIG. 5(a) is a plan view, and FIG. 5(b) is a schematic cross-sectional view taken along the line CC shown in FIG. 5(a). In the exterior body 1X of the second embodiment, the configuration of the exterior sheet 20 is the same as that of the first embodiment, and the configuration of the absorbent article 10X is different from that of the first embodiment. The absorbent article 10X of the second embodiment has an inspection member 19 for inspecting the health condition of the wearer.

[0081] The test member 19 may be a member that displays the wearer's health condition (color indicating the health condition) by an indicator, and for example, the test member described in JP 2020-022585 A can be applied. The temporary joint 18 may be disposed on the take-out side (take-out opening 5 side) D1 from the tip of the take-out side D1 of the test member 19. Since the temporary joint 18 is provided on the take-out side D1 from the test member 19, the rigidity of the area where the test member 19 is disposed can be increased, and deformation of the test member 19 when separating the absorbent article 10X and the outer sheet 20 can be suppressed. Note that it is sufficient that at least a part of the temporary joint 18 is provided on the take-out side D1 from the tip of the take-out side D1 of the test member 19, and at least a part of the temporary joint 18 may be provided on the opposite side D2 from the tip of the take-out side D1 of the test member 19. The temporary joint 18 may be provided in an area that overlaps with the test member 19 in the thickness direction T. According to this embodiment, twisting of the area where the inspection member 19 is arranged is suppressed, and the absorbent article 10X can be removed while protecting the inspection member 19.

[0082] The test member 19 may be disposed between the top sheet 11 and the absorbent layer 13. A film covering the skin side T1 of the test member 19 may be disposed between the top sheet 11 and the test member 19. The film covers at least a part of the test member 19, and can prevent the entire test member 19 from being soiled by body fluids, and can prevent the display section showing the test result in the test member 19 from being soiled by body fluids, thereby ensuring the visibility of the display section. The bonding strength between the top sheet 11 and the film may be higher than the shear force of the temporary bonding section 18. The shear force of the temporary bonding section 18 is the shear force between the top sheets 11 in a form in which the top sheets 11 are temporarily bonded to each other as in this embodiment. Since the shear force of the temporary bonding section 18 is relatively high, when the absorbent article is developed during use, the absorbent article can be developed while maintaining the bonded state between the top sheet 11 and the film, the function of the test member 19 can be maintained, the absorbent article can be used appropriately, and an appropriate test of the test member can be performed.

[0083] Next, an exterior body 1Y of an absorbent article 10Y according to a third embodiment will be described with reference to Figs. 6 to 8. Fig. 6 is a plan view of the exterior body 1Y in an unfolded state as viewed from the skin side T1, and Fig. 7 is a plan view of the exterior body 1Y in a folded state folded around an article fold line FL10 as viewed from the skin side T1. Fig. 8 is a diagram for explaining a separation mode of the absorbent article 10Y and the exterior sheet 20 in the exterior body 1Y according to the third embodiment. The exterior body 1Y of the third embodiment is folded around two fold lines along the width direction W before use. That is, the exterior body 1Y is folded in three. More specifically, the absorbent article 10Y is folded around a second article fold line FL102 located in front of the article fold line FL10 as a base point after being folded around the article fold line FL10 as a base point. In the present embodiment, in a state in which the packaging sheet 21, the release sheet 22, and the absorbent article 10Y are stacked together, the absorbent article 10Y, the packaging sheet 21, and the release sheet 22 are all folded in thirds about folds along the width direction W. Thus, the packaging crease FL21, the article crease FL10, and the release crease FL22 are formed simultaneously and overlap one another.

[0084] The release sheet 22 and the packaging sheet 21 are joined via a joining region 25. A plurality of joining regions 25 are arranged spaced apart in the front-rear direction L. The joining regions 25 are arranged in regions that do not overlap the packaging fold FL21 and the peeling fold FL22, and are arranged on both sides in the front-rear direction L, sandwiching the packaging fold FL21, the article fold FL10, and the peeling fold FL22 therebetween.

[0085] The absorbent article 10Y also has wings 7. Before the absorbent article 10Y is used, the wings 7 are folded toward the skin side T1 with the wing fold FL103 as a base point. When the absorbent article 10Y is used, the wings 7 are folded back toward the non-skin side T2 of the worn article with the wing fold FL103 as a base point. After the absorbent article 10Y is folded with the wing fold FL103 as a base point, it is folded with the article fold FL10 as a base point, and then folded with the second article fold FL102 as a base point. The packaging sheet 21 and the absorbent article 10Y are both folded with the two folds along the width direction as base points, so that the absorbent article 10 is individually packaged with the packaging sheet 21. The exterior body 1Y has a fastening tape 29 that fastens the outer edge of the packaging sheet in the individually packaged state. The fastening parts 15 of the absorbent article 10Y extend in the front-rear direction L, and a plurality of fastening parts 15 may be arranged in the width direction W at intervals.

[0086] The absorbent article 10Y of the third embodiment is configured to be separated from the exterior sheet 20 in the folded state shown in Fig. 7. In this folded state, the packaging sheet 21, the release sheet 22, and the absorbent article 10Y are unfolded from the individually packaged state with the second article fold FL102 as the base point. The absorbent article 10Y in the folded state is folded with the wing fold FL103 and the article fold FL10 as the base points. In addition, in the folded state, the packaging sheet 21 is folded with the packaging fold FL21 as the base point, and the outer parts of the stacked packaging sheets 21 in the width direction W are joined via the packaging joint 23. The rear end edge of the packaging sheet 21 in the unfolded state, in other words, the front-rear end edge of the packaging sheet 21 folded via the packaging fold FL21, forms the removal opening 5 when the absorbent article 10Y in the folded state is removed from the exterior sheet 20.

[0087] The temporary joining portion 18 joins the surfaces of the absorbent article 10Y facing each other in the folded state. In the absorbent article of this embodiment, in the folded state, a region where the top sheet 11 and the back sheet 12 constituting the non-skin side surface of the wing 7 face each other, and a region where the top sheets 11 face each other are provided. The temporary joining portion 18 is provided in at least one of the region where the top sheet 11 and the back sheet 12 face each other and the region where the top sheets 11 face each other. The temporary joining portion 18 of this embodiment is arranged to extend in the width direction W, and is arranged across the region where the top sheet 11 and the back sheet 12 face each other and the region where the top sheets 11 face each other. The temporary joining portion 18 is provided in a region that does not overlap the wing release sheet 26 that covers the fastening portion 16 provided on the wing 7. As a result, The absorbent article 10Y can be separated from the exterior sheet 20 while the opposing surfaces of the absorbent article 10Y are temporarily joined together by the temporary joints 18.

[0088] As shown in FIG. 8, when the absorbent article 10Y is separated from the exterior sheet 20, at least one of the front end of the absorbent article 10Y and the front end of the exterior sheet 20 is grasped and pulled in a direction away from each other while the absorbent article 10Y is folded. FIGS. 8(a) and (e) show a state in which the fastening part 15 and the release sheet 22 are separated near the front end of the absorbent article. When the separation of the absorbent article 10Y and the release sheet 22 progresses further from the state shown in FIGS. 8(a) and (e), the state shown in FIGS. 8(b) and (f) is obtained. FIGS. 8(b) and (f) show a state in which the separation of the absorbent article 10Y and the release sheet 22 progresses to the region overlapping with the temporary joint 18. When the separation of the absorbent article 10Y and the release sheet 22 progresses further from the state shown in FIGS. 8(b) and (f), the state shown in FIGS. 8(c) and (g) is obtained. 8(c) and (g) show a state where the separation of the absorbent article 10Y and the release sheet 22 has progressed to the vicinity of the article fold FL10. The absorbent article 10Y floats up from the packaging sheet 21 while maintaining the folded state via the temporary joint 18. At this time, since the joint region 25 is not provided over a certain range extending from the packaging fold FL21 and the peeling fold FL22 in the front-rear direction L, the release sheet 22 floats up from the packaging sheet 21 over a certain range across the peeling fold FL22, and the absorbent article 10Y floats up from the packaging sheet 21 while maintaining the folded state. When the absorbent article 10Y is further separated from the packaging sheet 21 from the state shown in FIG. 8(c) and (g), it becomes the state shown in FIG. 8(d) and (h). The absorbent article 10Y is separated from the packaging sheet 21 and the release sheet 22 while maintaining the joint by the temporary joint 18.

[0089] The absorbent layer 13 of the absorbent article 10Y is disposed inside the outer edge of the absorbent article in a plan view. That is, the outer edge of the absorbent layer 13 is separated from the outer edge of the absorbent article. The temporary joint 18 may straddle the outer edge of the absorbent layer 13. This configuration makes it possible to separate the absorbent article 10 from the exterior sheet 20 while suppressing wrinkling of the region where the absorbent layer 13 is disposed and also suppressing wrinkling of the region outside the absorbent layer 13 that has a relatively low rigidity.

[0090] (4) Manufacturing method of the exterior body of the absorbent article Next, an example of a method for manufacturing an exterior body configured in this manner will be described. For steps other than those described below, known methods for manufacturing absorbent articles and methods for manufacturing exterior bodies can be applied. The method for manufacturing an exterior body according to the embodiment is a method for manufacturing an exterior body 1, 1X, 1Y having an absorbent article 10, 10X, 10Y having a top sheet 11 that contacts the skin of a wearer and a back sheet 12 to which a fastening part 15 that fastens to a worn article is attached, and an exterior sheet 20 that is arranged on the non-skin side T2 of the absorbent article 10, 10X, 10Y and to which the fastening part 15 is fastened. The absorbent article may have an absorbent layer 13 arranged between the top sheet 11 and the back sheet 12.

[0091] The manufacturing method of the exterior body includes at least an adhesive application step, a folding step, and a temporary joining step. In the adhesive application step, an adhesive is applied to the surface of the non-skin side T2 of the top sheet 11. The adhesive may be an adhesive that bonds the top sheet 11 and the second sheet 14 as in the first embodiment, or an adhesive that bonds the top sheet 11 and the absorbent layer 13. The basis weight of the adhesive is not particularly limited as long as it is a basis weight necessary for passing through the top sheet 11 and being exposed to the skin side surface of the top sheet 11. The folding step is a step that follows the adhesive application step, and is a step of folding the absorbent article so that the top sheets face each other. The folding step may be a step of folding only the absorbent article, or a step of folding the release sheet and the packaging sheet 21 together with the absorbent article. The temporary joining step is a step that is performed simultaneously with the folding step or a step that follows the folding step, and presses the absorbent article folded in the folding step, and temporarily joins the top sheets to each other with the adhesive that has passed through the top sheet. When pressing the absorbent article, only the temporarily joined portion (the portion where the temporary joint 18 is provided) may be pressed, or the entire absorbent article may be pressed. According to such a manufacturing method, a temporary joint portion that joins the top sheets together can be provided. Therefore, when separating the absorbent article from the outer sheet, the absorbent article can be moved with the temporarily joined area integrated, and the absorbent article can be prevented from twisting when separating the outer sheet from the absorbent article.

[0092] Although the present invention has been described in detail using the above-mentioned embodiment, it is clear to those skilled in the art that the present invention is not limited to the embodiment described in this specification. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention defined by the description of the claims. Therefore, the description in this specification is intended to be illustrative and does not have any limiting meaning on the present invention. [Explanation of symbols]
