Abstract
Description
[Technical field]
[0001] The present invention relates to an absorbent article that is attached to a wearing article when used. [Background technology]
[0002] Patent Document 1 discloses an absorbent article that is attached to a worn article. The absorbent article has an absorbent core disposed at least in the crotch region. When the absorbent core is sandwiched between the legs of a wearer during use, it is pressed toward the inside in the width direction and is easily deformed. Therefore, it is required to suppress the deformation of the absorbent core. The absorbent article of Patent Document 1 has a core wrap sheet that covers the skin side of the absorbent core and a core wrap sheet that covers the non-skin side of the absorbent core, and the core wrap sheets are joined to each other on the outside in the width direction of the absorbent core.

[0003] [Patent Document 1] JP 2015-198798 A Summary of the Invention [Problem to be solved by the invention]
[0004] According to the above-mentioned absorbent article, when the absorbent article is subjected to a force directed inward in the width direction, the joint between the core wrap sheets can reduce the force applied to the outer part of the absorbent core, and can absorb the deformation of the absorbent core. However, the joint between the core wrap sheets arranged to sandwich the absorbent core increases the rigidity of the outer part of the absorbent core adjacent to the joint between the core wrap sheets, and there is a risk of discomfort due to the hardness of the absorbent core.
[0005] In addition, the duration of use of one absorbent article varies greatly depending on the user. As a result of the applicant's intensive research, it has been found that in Southeast Asia and the Middle East, it is customary to use one absorbent article for an entire day. In such a form in which an absorbent article is used for a long period of time, once the absorbent core is deformed before use or immediately after the start of use, the deformation becomes more significant near the end of use, and absorption performance may not be ensured. In particular, in an absorbent article used by being attached to a wearing article, the bond between the absorbent article and the wearing article may not be maintained or may shift due to the deformation of the absorbent core, and therefore it is particularly required to suppress the deformation of the absorbent core.
[0006] The present invention has been made in consideration of such problems, and aims to provide an absorbent article that can suppress deformation of the absorbent core while preventing the rigidity of the outer parts of the absorbent core from becoming too high. [Means for solving the problem]
[0007] An absorbent article according to one embodiment has a front-rear direction and a width direction perpendicular to each other, an absorbent core, a skin-side sheet covering the skin side of the absorbent core and extending outward in the width direction beyond the absorbent core, and a non-skin-side sheet covering the non-skin side of the absorbent core and extending outward in the width direction beyond the absorbent core. The absorbent article is attached to a worn article for use. The absorbent core has a central region in which a constricted portion is provided at the center of the absorbent core in the front-rear direction on the inside in the width direction, and front-rear regions located outside the front-rear direction outer edges of the constricted portion. A layered region in which the skin-side sheet and the non-skin-side sheet are layered is provided outside the outer edges of the absorbent core in the width direction. The laminated region has a first region extending outward in the width direction from the outer edge of the central region, where the skin side sheet and the non-skin side sheet are joined, and a second region extending outward in the width direction from the outer edges of the front and rear regions, where the skin side sheet and the non-skin side sheet overlap without being joined.
[0008] A package for absorbent articles according to one embodiment individually packages absorbent articles with a packaging sheet. The absorbent article has a front-rear direction and a width direction perpendicular to each other, an absorbent core, a skin-side sheet covering the skin side of the absorbent core and extending outward in the width direction beyond the absorbent core, a non-skin-side sheet covering the non-skin side of the absorbent core and extending outward in the width direction beyond the absorbent core, an adhesive portion disposed on the non-skin side of the absorbent article and bonded to a worn article, and a release sheet releasably covering the adhesive portion. The absorbent article is not bonded to the packaging sheet and is movable within the packaging sheet. A bonding region where the skin-side sheet and the non-skin-side sheet are bonded is provided outside the outer edge of the absorbent core in the width direction. [Brief description of the drawings]

[0010] (1) Overview of the embodiment At least the following points will become apparent from the description of this specification and the accompanying drawings. The absorbent article according to the first aspect has a front-rear direction and a width direction perpendicular to each other, an absorbent core, a skin-side sheet covering the skin side of the absorbent core and extending outward in the width direction beyond the absorbent core, and a non-skin-side sheet covering the non-skin side of the absorbent core and extending outward in the width direction beyond the absorbent core. The absorbent article is attached to a worn article for use. The absorbent core has a central region in which a constricted portion is provided at the center of the absorbent core in the front-rear direction on the inside in the width direction, and front-rear regions located outside the front-rear direction outer edges of the constricted portion. A layered region in which the skin-side sheet and the non-skin-side sheet are layered is provided outside the outer edges of the absorbent core in the width direction. The laminated region has a first region extending from the outer edge of the central region to the outside in the width direction, where the skin side sheet and the non-skin side sheet are joined, and a second region extending from the outer edge of the front and rear regions to the outside in the width direction, where the skin side sheet and the non-skin side sheet overlap without being joined. The central region of the absorbent core is sandwiched between both legs when worn, and is likely to receive a force directed inward in the width direction. In addition, a constricted portion is formed in the central region of the absorbent core, and the width of the absorbent core is shorter than that of the front and rear regions. Therefore, the central region of the absorbent core is likely to deform when it receives a force directed inward in the width direction. Since the skin side sheet and the non-skin side sheet are joined in the first region, the force applied to the outer portion of the central region of the absorbent core can be reduced, and deformation of the absorbent core can be suppressed. On the other hand, the front and rear regions of the absorbent core do not have a constricted portion, and the width of the absorbent core is longer than that of the central region. Therefore, the front and rear regions of the absorbent core are likely to come into contact with the skin when moving the legs, sitting, or lying down. Since the skin side sheet and the non-skin side sheet are not joined in the second region, the rigidity of the outer parts of the front and rear regions of the absorbent core is prevented from becoming too high, and discomfort caused by the absorbent core becoming too hard can be suppressed.
[0011] According to a preferred embodiment, the invention according to embodiment 2 may have the following features in the invention according to embodiment 1. A pair of compressed parts are provided, which extend in the front-rear direction across the center of the width direction of the absorbent core and compress at least the absorbent core in the thickness direction. The compressed parts are provided at least in the central region, on the inside in the width direction of the constricted parts. Since the central region has a constricted part, its width length is relatively short and side leakage is likely to occur. However, since a pair of compressed parts are provided, the fit to the excretion opening can be improved and side leakage can be suppressed by deforming the absorbent core with the compressed parts as a base point. In addition, the rigidity of the central region of the absorbent core is improved by the pair of compressed parts, and deformation of the central region of the absorbent core can be suppressed. In addition, deformation with the compressed parts as a base point shortens the width direction of the absorbent core, suppressing contact and rubbing against the legs when worn and reducing the discomfort of contact with the absorbent core.
[0012] According to a preferred embodiment, the invention according to embodiment 3 may have the following features in the invention according to embodiment 2. The compression section compresses at least the absorbent core and the skin side sheet from the skin side toward the non-skin side. The widthwise length of the laminated region in the central region is longer than the distance between the compression section and the inner edge of the constricted portion. The absorbent core and the skin side sheet are compressed from the skin side toward the non-skin side in the compression section. The outer edge of the skin side sheet is relatively likely to rise up from the absorbent core due to compression, and it may be difficult to maintain the bonded state between the skin side sheet and the non-skin side sheet located to the side of the absorbent core. However, since the widthwise length of the laminated region in the central region is relatively long, the bonded state between the skin side sheet and the non-skin side sheet located to the side of the absorbent core can be maintained, the outer edge of the absorbent core can be prevented from being exposed, and deformation of the outer edge of the absorbent core can be prevented. In addition, since the distance between the compression section and the inner edge of the constricted portion is relatively short, when a force toward the inside in the width direction is applied to the constricted portion, the force is easily applied to the compression section. This prevents the absorbent core from becoming wider and prevents deformation of the outer edges of the absorbent core.
[0013] According to a preferred embodiment, the invention according to embodiment 4 may have the following features in the invention according to any one of embodiments 1 to 3. The widthwise length of the first region is longer than the widthwise distance between the compressed portion and the inner edge of the constricted portion. According to this embodiment, the force with which the central region of the absorbent core is pressed inward in the widthwise direction is reduced due to the presence of the first region (the region where two sheets are joined), and deformation of the absorbent core can be suppressed. In addition, because the widthwise length of the first region is relatively long, it is easier to maintain the joined state between the skin side sheet and the non-skin side sheet, and deformation of the outer edge of the absorbent core can be further suppressed.
[0014] According to a preferred embodiment, the invention according to embodiment 5 may have the following features in the inventions according to embodiments 1 to 4. The outer edge of the first region is located outboard in the width direction of the midpoint between the inner edge of the constricted portion and the outer edge of the constricted portion. According to this embodiment, the skin side sheet and the non-skin side sheet are joined in an area of more than half of the width direction of the constricted portion. The two-layer sheet in the first region can reduce contact in the central region of the absorbent core, and can suppress deformation of the absorbent core. In addition, the joined state of the skin side sheet and the non-skin side sheet located to the side of the absorbent core can be maintained, and exposure of the outer edge of the absorbent core can be suppressed, suppressing deformation of the outer edge of the absorbent core.
[0015] 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. In the width direction, the outer edge of the skin side sheet is located outside the outer edge of the non-skin side sheet. According to this embodiment, the width length of the skin side sheet and the width length of the non-skin side sheet are different, so that the rigidity changes stepwise in the laminated region. Therefore, the external force applied to the outer edge of the absorbent core can be absorbed and the impact against the outer edge of the absorbent core can be suppressed. In addition, since the user notices that the skin side sheet is arranged over a wide range in the width direction beyond the absorbent core, the user gets the impression that the sheet can absorb the force when the absorbent core receives a force from the outside in the width direction, and deformation of the absorbent core is suppressed, which makes it easy to feel secure about the absorption performance and wearing comfort.
[0016] According to a preferred embodiment, the invention according to embodiment 7 may have the following features in the invention according to embodiment 6. An adhesive region is provided with an adhesive that bonds the skin side sheet and the non-skin side sheet. The adhesive region is disposed across the outer edge of the skin side sheet. According to this embodiment, the bonded state between the skin side sheet and the non-skin side sheet can be maintained, exposure of the outer edge of the absorbent core can be suppressed, and deformation of the outer edge of the absorbent core can be suppressed.
[0017] According to a preferred embodiment, the invention according to embodiment 8 may have the following features in the inventions according to embodiments 1 to 7. In the width direction, the outer edge of the non-skin side sheet is located outside the outer edge of the skin side sheet. According to this embodiment, the width direction length of the skin side sheet and the width direction length of the non-skin side sheet are different, so that the stiffness changes stepwise in the laminated region. Therefore, the external force acting on the outer edge of the absorbent core can be absorbed, and the impact against the outer edge of the absorbent core can be suppressed.
[0018] According to a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to embodiment 8. An adhesive region is provided with an adhesive that adheres the skin side sheet and the non-skin side sheet. The adhesive region is disposed across the outer edge of the non-skin side sheet. According to this embodiment, the bonded state between the skin side sheet and the non-skin side sheet can be maintained, exposure of the outer edge of the absorbent core can be suppressed, and deformation of the outer edge of the absorbent core can be suppressed.
[0019] The invention according to the tenth aspect is a package for absorbent articles. The package for absorbent articles individually packages absorbent articles with a packaging sheet. The absorbent article has a front-rear direction and a width direction that are mutually perpendicular, an absorbent core, a skin-side sheet that covers the skin side of the absorbent core and extends outward in the width direction beyond the absorbent core, a non-skin-side sheet that covers the non-skin side of the absorbent core and extends outward in the width direction beyond the absorbent core, an adhesive portion that is disposed on the non-skin side of the absorbent article and is bonded to a worn article, and a release sheet that releasably covers the adhesive portion. The absorbent article is not bonded to the packaging sheet and is movable within the packaging sheet. A bonding region where the skin-side sheet and the non-skin-side sheet are bonded is provided outside the outer edge of the absorbent core in the width direction. According to this aspect, the packaging body allows the absorbent article to move within the packaging sheet, and when force is applied to the packaging body, the absorbent article moves within the packaging body to absorb the deformation, reducing the force applied to the absorbent article and suppressing deformation of the absorbent article. Furthermore, since the joint region where the skin side sheet and the non-skin side sheet are joined is provided outside the outer edge of the absorbent core in the width direction, even if the absorbent article moves within the packaging body, the joined state of the skin side sheet and the non-skin side sheet is maintained, the outer edge of the absorbent core is prevented from being exposed, and deformation of the outer edge of the absorbent core is suppressed.
[0020] According to a preferred embodiment, the invention according to embodiment 11 may have the following features in the invention according to embodiment 10. The absorbent article is folded with a crease along the width direction as a base point. The packaging joints that join the packaging sheets together are located on both sides of the packaging body in the front-rear direction of the absorbent article and are arranged along the crease. The outer edges of the absorbent article in the width direction extend along the front-rear direction of the absorbent article. The packaging joints are located on both sides of the packaging body in the front-rear direction of the absorbent article and extend along the width direction. Since the outer edges of the absorbent article in the width direction and the packaging joints are arranged perpendicular to each other, deformation of the absorbent core caused by the outer edges of the absorbent core hitting the packaging joints can be suppressed even if the absorbent article moves within the packaging body.
[0021] According to a preferred embodiment, the invention according to embodiment 12 may have the following features in the invention according to embodiment 10 or embodiment 11. The skin side sheet and the non-skin side sheet extend further outward in the front-to-rear direction than the absorbent core. The joining region is provided further outward in the front-to-rear direction than the outer edge of the absorbent core in the front-to-rear direction. According to this embodiment, the joining state between the skin side sheet and the non-skin side sheet can be maintained even at the front and rear ends of the absorbent article, exposure of the outer edge of the absorbent core can be suppressed, and deformation of the outer edge of the absorbent core can be suppressed.

In this embodiment, both the first core wrap sheet 31 and the second core wrap sheet 32 are provided. The length in the width direction W of the first core wrap sheet 31 and the length in the width direction W of the second core wrap sheet 32 may be different. In this embodiment, the length in the width direction W of the first core wrap sheet 31 is longer than the length in the width direction W of the second core wrap sheet 32.
[0029] The absorbent article 1 may be provided with a compressed section 38 that compresses at least the absorbent core 30. The compressed section 38 needs to compress at least the absorbent core 30, and may compress the absorbent core 30, the core wrap sheet, and the top sheet 10, or may compress the absorbent core 30 and the core wrap sheet. The compressed sections 38 are arranged in a pair on either side of the center of the width direction W of the absorbent core 30, and each may extend in the front-rear direction L.
[0030] The absorbent article 1 has a skin-side sheet 50 that covers the skin side T1 of the absorbent core 30 and extends outward in the width direction W beyond the absorbent core 30, and a non-skin-side sheet 55 that covers the non-skin side T2 of the absorbent core 30 and extends outward in the width direction W beyond the absorbent core 30. The skin-side sheet 50 is a sheet that contacts the skin side of the absorbent core 30, and in this embodiment, it is the first core wrap sheet 31. In a configuration that does not have the first core wrap sheet 31, the skin-side sheet 50 may be the top sheet 10. The non-skin-side sheet 55 is a sheet that contacts the non-skin side of the absorbent core 30, and in this embodiment, it is the second core wrap sheet 32. In a configuration that does not have the second core wrap sheet 32, the non-skin-side sheet 55 may be the back sheet 20. In addition to the combination of the present embodiment, the following combinations of the skin-side sheet 50 and the non-skin-side sheet 55 can be exemplified. The skin side sheet 50 may be constituted by the top sheet 10, and the non-skin side sheet 55 may be constituted by the second core wrap sheet 32. Alternatively, the skin side sheet 50 may be constituted by the first core wrap sheet 31, and the non-skin side sheet 55 may be constituted by the back sheet 20.
[0031] At least one of the non-skin side of the skin side sheet 50 and the skin side of the non-skin side sheet 55 is provided with an adhesive adhesive region AR. In this embodiment, the adhesive region AR is provided on the non-skin side of the skin side sheet 50 and not on the skin side of the non-skin side sheet 55. However, in a modified example, the adhesive region AR may be provided on both sides of the skin side sheet 50 and the non-skin side sheet 55, or may be provided on the non-skin side sheet 55 and not on the skin side sheet 50. Preferably, the adhesive region AR may be provided on the sheet having the longer length in the width direction W out of the skin side sheet 50 and the non-skin side sheet 55. The skin side sheet 50 is adhered to the absorbent core 30, the non-skin side sheet 55, etc., which the skin side sheet 50 overlaps, in the region where the adhesive region AR is provided. Similarly, in a form in which the adhesive region AR is provided, the non-skin side sheet 55 is adhered to the absorbent core 30, the skin side sheet 50, etc., which the non-skin side sheet 55 overlaps, in the region where the adhesive region AR is provided. The adhesive is not particularly limited, and may be, for example, an HMA type adhesive. The adhesive may be arranged in a line shape such as a spiral or omega shape by a non-contact coating method, or may be arranged with a predetermined width by a contact coating method. In a form in which the adhesive is arranged in a line shape such as by spiral coating, the part surrounded by the linear adhesive is not spatially bonded, but constitutes the adhesive region AR of the present invention. That is, the part where the skin side sheet 50 and the non-skin side sheet 55 are bonded in this embodiment includes not only the part where the skin side sheet 50 and the non-skin side sheet 55 are bonded, but also the part surrounded by the bonded part (the gap part between the adhesive). The range of the adhesive region AR in the front-rear direction L may be the entire area of the skin side sheet 50 in the front-rear direction L and the entire area of the non-skin side sheet 55 in the front-rear direction L. The adhesive region AR may have a first adhesive region AR1 extending from the center in the width direction of the absorbent core 30 to the outside in the width direction W, and a second adhesive region AR2 spaced apart from the first adhesive region AR1 and positioned outside the first adhesive region AR1 in the width direction W. In other words, a non-adhesive region NR may be provided between the first adhesive region AR1 and the second adhesive region AR2.
[0032] The absorbent article 1 of this embodiment is configured to suppress deformation of the absorbent core 30 while suppressing the rigidity of the outer portion of the absorbent core 30 from becoming too high. Next, a configuration for suppressing deformation of the absorbent core 30 while suppressing the rigidity of the outer portion of the absorbent core 30 from becoming too high will be described in detail. A laminated region RP in which the skin side sheet 50 and the non-skin side sheet 55 are laminated is provided on the outer side of the outer edge 30E of the absorbent core 30 in the width direction W. The inner edge of the laminated region RP is the outer edge 30E of the absorbent core 30. The outer edge 32E of the second core wrap sheet 32 as the non-skin side sheet 55 of this embodiment is located inside in the width direction W from the outer edge 31E of the first core wrap sheet 31 as the skin side sheet 50. The outer edge of the laminated region RP is the outer edge 32E of the second core wrap sheet 32. The laminated region RP includes an area where the skin side sheet 50 and the non-skin side sheet 55 overlap in a joined state, and an area where the skin side sheet 50 and the non-skin side sheet 55 overlap in a non-jointed state. The area where the skin side sheet 50 and the non-skin side sheet 55 overlap in a joined state is an area where at least one of the adhesive regions AR is provided. The area where the skin side sheet 50 and the non-skin side sheet 55 overlap in a non-jointed state is an area where the non-adhesive region NR overlaps. The laminated region RP is provided in an area outside the outer edge of the absorbent core 30 in the width direction, and two sheets (skin side sheet 50 and non-skin side sheet 55) are arranged with the absorbent core 30 sandwiched between them. Therefore, when an external force is applied from the outside in the width direction W of the absorbent article 1, the presence of the two sheets (skin side sheet 50 and non-skin side sheet 55) can reduce contact with the outer part of the absorbent core 30, and deformation of the absorbent core 30 can be suppressed. The laminated region RP may be provided at least in the crotch region S3, but may be preferably provided over the entire area in the front-rear direction L of the absorbent core 30.
[0033] As shown in Figs. 3 and 4, the laminated region RP has a first region RP1 extending from the outer edge of the central region RC of the absorbent core 30 outward in the width direction, where the skin side sheet 50 and the non-skin side sheet 55 are joined, and a second region RP2 extending from the outer edge 31E of the front and rear regions RS of the absorbent core 30 outward in the width direction W, where the skin side sheet 50 and the non-skin side sheet 55 overlap without being joined. The first region RP1 is a region in which a first adhesive region AR1 is provided. The inner edge of the first region RP1 is the outer edge of the absorbent core 30 in the central region RC. The outer edge of the first region RP1 may be the outer edge of the laminated region RP, or may be separated from the outer edge of the laminated region RP and located in the width direction W more inward than the outer edge of the laminated region RP as in this embodiment. The first adhesive region AR1 in this embodiment is located in the width direction W more inward than the outer edge of the front and rear regions RS of the absorbent core 30. Therefore, a non-adhesive region NR is provided at the outer edge of the front and rear regions RS of the absorbent core 30. Between the outer edge of the first region RP1 and the outer edge of the laminated region RP, there may be provided a region where the skin side sheet 50 and the non-skin side sheet 55 overlap in a non-bonded state (where a non-bonded region NR is provided). The inner edge of the second region RP2 is the outer edge 30E of the absorbent core 30 in the front and rear regions RS. The outer edge of the second region RP2 may be the outer edge of the laminated region RP as in this embodiment, or may be separated from the outer edge of the laminated region RP and located inside the outer edge of the laminated region RP in the width direction W. Between the outer edge of the first region RP1 and the outer edge of the laminated region RP, there may be provided a region where the skin side sheet 50 and the non-skin side sheet 55 overlap in a bonded state (where a second bonded region AR2 is provided). The boundary between the first bonded region AR1 and the non-bonded region NR may be located between the inner edge 35I of the constriction 35 and the outer edge of the absorbent core 30 in the front and rear regions RS in the width direction. The boundary between the non-adhesive region NR and the second adhesive region AR2 may be located, in the width direction, outside the outer edges of the front and rear regions RS of the absorbent core 30. Therefore, the skin side sheet 50 and the non-skin side sheet 55 are not joined to the outer parts (a certain range extending from the outer edges to the inside in the width direction) of the front and rear regions RS of the absorbent core 30. The length in the width direction W of the non-adhesive region NR may be 5 mm or more and 10 mm or less.Since the length in the width direction W of the non-adhesive region NR is 5 mm or more, even if a manufacturing error occurs, the non-adhesive region NR can be easily arranged so as to overlap with the outer edge in the front and rear regions RS of the absorbent core 30. Furthermore, since the length in the width direction W of the non-adhesive region NR is 10 mm or less, the range in which the skin side sheet 50 and the non-skin side sheet 55 are not joined together does not become too long, and lifting of the skin side sheet 50 and the non-skin side sheet 55 can be suppressed. Furthermore, the length in the width direction W of the non-adhesive region NR may be longer than the thickness of the absorbent core 30 to which the non-adhesive region NR is adjacent. Even if a manufacturing error occurs, the non-adhesive region NR can be easily arranged so as to overlap with the outer edge in the front and rear regions RS of the absorbent core 30.
[0034] The central region RC of the absorbent core 30 is sandwiched between both legs when worn, and is likely to receive a force directed inward in the width direction W. In addition, the central region RC of the absorbent core 30 has a constricted portion 35 formed therein, and the width of the absorbent core 30 is shorter than that of the front and rear regions RS. Therefore, the central region RC of the absorbent core 30 is likely to deform when it receives a force directed inward in the width direction W. However, since the skin side sheet 50 and the non-skin side sheet 55 are joined in the first region RP1, the force applied to the outer portion of the central region RC of the absorbent core 30 can be reduced, and deformation of the central region RC of the absorbent core 30 can be suppressed. Furthermore, if the excretion opening contact region is located in the central region RC, the bonding strength between the members of the central region RC is likely to decrease due to absorption of body fluids such as menstrual blood. However, since the first region RP1 is provided on the side of the central region RC, deformation of the central region RC of the absorbent core 30 can be suppressed. On the other hand, the front and rear regions RS of the absorbent core 30 do not have the constricted portion 35, and the width of the absorbent core 30 is longer than that of the central region RC. Therefore, the front and rear regions RS of the absorbent core 30 are likely to come into contact with the skin when moving the legs, sitting, or lying down. In the second region RP2, the skin side sheet 50 and the non-skin side sheet 55 are not joined, so that the stiffness of the outer parts of the front and rear regions RS of the absorbent core 30 is prevented from becoming too high, and discomfort caused by the hardness of the absorbent core 30 can be suppressed. In addition, the skin side sheet 50 and the non-skin side sheet 55 are not joined to the outer parts of the front and rear regions RS of the absorbent core 30, so that the stiffness of the outer parts of the front and rear regions RS of the absorbent core can be prevented from becoming too high. By providing the first region on the side of the region where the constricted portion 35 is provided and the second region on the side of the region where the constricted portion is not provided, it is possible to suppress the deformation of the absorbent core by the joint between the core wrap sheets, and to prevent the stiffness of the absorbent core from becoming too high by not providing the joint between the core wrap sheets. Even when one absorbent article is used throughout the day, the deformation of the absorbent core is suppressed to ensure continued absorption performance, and the rigidity of the absorbent core is suppressed to allow for long-term use without discomfort.
[0035] The compressed parts 38 may be provided at least in the central region RC, on the inside in the width direction W of the constricted parts 35. The compressed parts 38 may be provided at least in the central region RC, and may be provided across the front and rear regions RS. The central region RC of the absorbent core 30 has a relatively short length in the width direction W because the constricted parts 35 are formed, and side leakage is likely to occur. However, because the pair of compressed parts 38 is provided, the absorbent core 30 can be deformed with the compressed parts 38 as a base point to improve the fit to the excretory opening and suppress the occurrence of side leakage. In addition, the rigidity of the central region RC of the absorbent core 30 is improved by the pair of compressed parts 38, and deformation of the central region RC of the absorbent core 30 can be suppressed. In addition, deformation with the compressed parts 38 as a base point shortens the width direction length of the absorbent core 30, suppressing contact and rubbing against the legs when worn, and reducing the discomfort of contact with the absorbent core 30.
[0036] The compression section 38 may at least compress the absorbent core 30 and the skin side sheet 50 from the skin side T1 toward the non-skin side T2. The widthwise length L1 of the laminated region RP in the central region RC may be longer than the distance L2 in the widthwise direction W between the compression section 38 and the inner edge (the innermost constricted position) 35I of the constricted portion 35. The absorbent core 30 and the skin side sheet 50 are compressed in the compression section 38 from the skin side T1 toward the non-skin side T2. Due to compression, the outer edge 50E of the skin side sheet 50 is relatively likely to rise up from the absorbent core 30, which may make it difficult to maintain the bond between the skin side sheet 50 and the non-skin side sheet 55 located laterally of the absorbent core 30. However, since the length L1 of the laminated region RP in the width direction W in the central region RC is relatively long, the bonded state between the skin side sheet 50 and the non-skin side sheet 55 located laterally of the absorbent core 30 is maintained, the outer edge 30E of the absorbent core 30 is prevented from being exposed, and deformation of the outer edge 30E of the absorbent core 30 can be suppressed. Furthermore, since the distance L2 between the compressed portion 38 and the inner edge 35I of the constricted portion 35 is relatively short, when a force toward the inside in the width direction W is applied to the constricted portion 35, the force is easily applied to the compressed portion 38. Therefore, the widthwise contraction of the absorbent core 30 can be suppressed, and deformation of the outer edge of the absorbent core 30 can be suppressed, and the fit to the crotch can be improved by deforming with the compressed portion 38 as a base point. Note that, in a form in which L1 and L2 change, it is sufficient to satisfy L1>L2 at any position in the central region RC, but preferably, L1>L2 may be satisfied at the inner edge 35I of the constricted portion 35.
[0037] The length L3 in the width direction W of the first region RP1 may be longer than the distance L2 in the width direction W between the compressed portion 38 and the inner edge 35I of the constricted portion 35. The presence of the first region (region where two sheets are joined) RP1 reduces the force with which the central region RC of the absorbent core 30 is pressed inward in the width direction W, making it less likely to deform. Furthermore, because the length L3 in the width direction W of the first region RP1 is relatively long, it is easier to maintain the joined state between the skin side sheet 50 and the non-skin side sheet 55, and deformation of the outer edge of the absorbent core 30 can be more effectively suppressed.
[0038] The outer edge of the first region RP1 may be located outside the width direction W of the intermediate position 35CW between the inner edge 35I of the constricted portion 35 and the outer edge 35E of the constricted portion 35 in the width direction W. According to this embodiment, the skin side sheet 50 and the non-skin side sheet 55 are joined in more than half of the region in the width direction W of the constricted portion 35. Therefore, the two-layer sheet in the first region RP1 can reduce the contact of the central region RC of the absorbent core 30, and the deformation of the absorbent core 30 can be further suppressed. In addition, the joined state of the skin side sheet 50 and the non-skin side sheet 55 located laterally of the absorbent core 30 can be maintained, the outer edge 30E of the absorbent core 30 can be prevented from being exposed, and the deformation of the outer edge 30E of the absorbent core 30 can be suppressed. More preferably, the outer edge of the first region RP1 may be located outside the width direction W of the outer edge 35E of the constricted portion 35. According to this embodiment, the contact of the external force with the constricted portion 35 can be further suppressed.
[0039] In the width direction W, the outer edge 50E of the skin side sheet 50 may be located outside the outer edge 55E of the non-skin side sheet 55. Since the length of the skin side sheet 50 in the width direction W is different from the length of the non-skin side sheet 55 in the width direction, the rigidity changes stepwise in the laminated region RP. Therefore, the external force applied to the outer edge 30E of the absorbent core 30 can be absorbed stepwise, and the contact with the outer part of the absorbent core 30 can be suppressed. In addition, the skin side sheet 50 is located closer to the skin side T1 than the absorbent core 30, and is easily visible from the skin side T1 of the absorbent article 1. When the user notices the presence of the skin side sheet 50, which has a relatively long width, the user gets the impression that the body fluid can be absorbed over a wide range, and is likely to feel reassured about the absorption performance. Furthermore, when the user notices that the skin side sheet 50 is positioned over a wide area in the width direction W beyond the absorbent core 30, the user gets the impression that when the absorbent core 30 receives force from the outside in the width direction, the force can be absorbed by the sheet and deformation of the absorbent core 30 is suppressed, which makes it easier for the user to feel reassured about the absorption performance and wearing comfort.
[0040] The adhesive region AR may be disposed across the outer edge 50E of the skin side sheet 50. According to this embodiment, the adhesive state between the skin side sheet 50 and the non-skin side sheet 55 is maintained, the outer edge 30E of the absorbent core 30 is prevented from being exposed, and deformation of the outer portion of the absorbent core 30 can be prevented. The adhesive region AR may be provided over the entire width direction W of the first region RP1. The adhesive region AR may also be across the outer edge 50E of the skin side sheet 50 and across the outer edge 55E of the non-skin side sheet 55. This configuration makes it easier to maintain the adhesive state between the skin side sheet 50 and the non-skin side sheet 55.
[0041] In a modified example, the outer edge 55E of the non-skin side sheet 55 may be located outside the outer edge 50E of the skin side sheet 50 in the width direction W. Even with this configuration, the length of the skin side sheet 50 in the width direction W is different from the length of the non-skin side sheet 55 in the width direction W, so that the rigidity changes stepwise in the laminated region RP. Therefore, the external force applied to the outer part of the absorbent core 30 can be absorbed stepwise to suppress the contact with the outer part of the absorbent core 30. In addition, since the non-skin side sheet 55 extends outward in the width direction from the skin side sheet 50, when the non-skin side sheet 55 is made of a hydrophobic sheet, a large amount of diffusion from the absorbent core can be suppressed, so that the anxiety of the appearance of leakage can be reduced. In this modified example, the adhesive region AR may be arranged across the outer edge 55E of the non-skin side sheet 55. According to this embodiment, the bonded state between the skin side sheet 50 and the non-skin side sheet 55 is maintained, the outer edges 30E of the absorbent core 30 are prevented from being exposed, and deformation of the outer parts of the absorbent core 30 is prevented.
[0042] In a modified example, the absorbent article 1 may have wings that are folded back to the non-skin side of the worn article when in use. At least one of the outer edge of the skin side sheet 50 and the outer edge of the non-skin side sheet 55 may be located outside the root of the wing in the width direction. The root of the wing is a part that is narrowed inward in the width direction W and is located at the front end edge of the wing and the rear end edge of the wing. When the absorbent article 1 is in use, the wing is folded back to the non-skin side of the worn article from a fold that connects the front root and the rear root of the wing to each other as a base point. Since at least one of the skin side sheet 50 and the non-skin side sheet 55 is arranged across the fold of the wing, the rigidity of the base point for folding back the wing is ensured and the folding base point is stabilized. Therefore, it is possible to suppress the contact with the absorbent core 30 when pressed in the width direction by the legs or the like when worn.
[0043] The laminated region RP may also be disposed outside the front-rear direction L of the end edge of the absorbent core 30. Specifically, the laminated region RP may be provided in at least one of the region extending forward from the front end edge 30F of the absorbent core 30 and the region extending rearward from the rear end edge 30R of the absorbent core 30. It is also preferable that the skin side sheet 50 and the non-skin side sheet 55 are joined in at least a part of the laminated region RP located outside the front-rear direction L of the end edge of the absorbent core 30. According to this configuration, the joined state of the skin side sheet 50 and the non-skin side sheet 55 can be maintained even at the front end and rear end of the absorbent article 1, the outer edge of the absorbent core 30 is prevented from being exposed, and deformation of the outer edge of the absorbent core 30 can be prevented.
[0044] In a configuration in which the laminated region RP is disposed not only on the outer side of the absorbent core 30 in the width direction but also on the outer side of the absorbent core 30 in the front-rear direction, the four corners of the absorbent core 30 may be curved such as a circular arc rather than at right angles. With this configuration, the area of the laminated region RP and the area of the joining region between the skin side sheet 50 and the non-skin side sheet 55 can be secured around the four corners of the absorbent core 30. In particular, deformation of the absorbent core 30 can be suppressed when an external force is applied from an oblique direction.
[0045] Next, the package 100 for the absorbent article (hereinafter, referred to as the package) will be described with reference to FIG. 5. FIG. 5(a) is a plan view of the package, and FIG. 5(b) is a cross-sectional view taken along the line CC shown in FIG. 5(a). The package 100 is configured to suppress deformation of the absorbent core 30 while suppressing excessive stiffness of the outer portion of the absorbent core 30, similar to the absorbent article 1 described above. The package 100 individually packages the absorbent article 1 with a packaging sheet 80. The absorbent article 1 constituting the package 100 may be the absorbent article 1 according to the above embodiment, or may be different. The absorbent article 1X constituting the package 100 will be described below, but the same reference numerals will be used to omit the description of the same configuration as the absorbent article 1 described above.
[0046] The absorbent article 1X has a front-rear direction L and a width direction W that are perpendicular to each other, an absorbent core 30, a skin-side sheet 50 that covers the skin side T1 of the absorbent core 30 and extends outward in the width direction W beyond the absorbent core 30, a non-skin-side sheet 55 that covers the non-skin side T2 of the absorbent core 30 and extends outward in the width direction W beyond the absorbent core 30, an adhesive part 60 that is disposed on the non-skin side of the absorbent article 1 and is bonded to a worn article, and a release sheet 65 that releasably covers the adhesive part 60. The absorbent article 1 is not bonded to the packaging sheet 80 and is movable within the packaging body 100. In this embodiment, the release sheet 65 of the absorbent article 1 is not bonded to the packaging sheet 80. That is, no bonding means is provided for bonding the absorbent article 1 to the packaging sheet 80. In addition, in a general packaging body, the absorbent article and the packaging sheet are folded together with the absorbent article placed on the packaging sheet. However, the absorbent article 1 of the present embodiment is folded at a crease extending in the width direction and is contained in the packaging sheet. That is, the absorbent article 1 and the packaging sheet 80 are folded separately. Therefore, in the individually packaged state (where the absorbent article 1 is contained in the packaging sheet 80) shown in FIG. 5, the absorbent article 1 is configured to be movable. In a general packaging body, a release sheet is fixed in the packaging sheet, and the absorbent article cannot move in the packaging sheet. On the other hand, in the packaging body according to the present invention, the absorbent article 1X can move in the packaging body 100, and when a force is applied to the packaging body 100, the absorbent article 1X moves in the packaging body 100 to absorb the deformation, thereby reducing the force applied to the absorbent article 1X and suppressing the deformation of the absorbent article.
[0047] The absorbent article is provided with a joining region (AR, RP1 in the above-mentioned embodiment) where the skin side sheet 50 and the non-skin side sheet 55 are joined. The joining region is provided in at least a part of a region located outside the absorbent core 30 in a plan view, and is provided outside the outer edge 30E of the absorbent core 30 in the width direction W. Therefore, even if the absorbent article 1X moves within the package 100, the joining state between the skin side sheet 50 and the non-skin side sheet 55 can be maintained, the outer edge 30E of the absorbent core 30 can be prevented from being exposed, and deformation of the outer part of the absorbent core 30 can be prevented. In addition, if the outer part of the absorbent core 30 is partially deformed, the absorbent core 30 may become locally hard. However, by suppressing deformation of the outer part of the absorbent core 30, it is possible to prevent the rigidity of the outer part of the absorbent core 30 from increasing.
[0048] Preferably, the absorbent article 1X has a laminated region RP provided on the outer side of the outer edge of the absorbent core 30 in the width direction, similar to the absorbent article 1. Therefore, the force applied to the outer edge 30E of the absorbent core 30 can be reduced by the two sheets of the laminated region. Preferably, the absorbent article 1X has a first region RP1 and a second region RP2, similar to the absorbent article 1. Therefore, the force applied to the outer part of the central region RC of the absorbent core 30 can be reduced, and while suppressing deformation of the central region RC of the absorbent core 30, the rigidity of the outer parts of the front and rear regions RS of the absorbent core 30 can be prevented from becoming too high, and discomfort caused by the absorbent core 30 becoming stiff can be suppressed.
[0049] Preferably, in the absorbent article 1X, similarly to the absorbent article 1, the skin side sheet 50 and the non-skin side sheet 55 extend further outward in the front-to-rear direction L than the absorbent core 30, and the joining region may be provided further outward in the front-to-rear direction L than the outer edge in the front-to-rear direction of the absorbent core 30. With this configuration, the joined state of the skin side sheet 50 and the non-skin side sheet 55 can be maintained even at the front end and rear end of the absorbent article, exposure of the outer edge of the absorbent core 30 can be suppressed, and deformation of the outer edge of the absorbent core 30 can be suppressed.
[0050] The absorbent article 1X may be folded with a crease FL along the width direction as a base point. The packaging joints 81 that join the packaging sheets 80 together are located on both sides of the packaging body 100 in the front-rear direction L of the absorbent article, and are arranged along the crease FL. The outer edges of the absorbent article in the width direction extend along the front-rear direction of the absorbent article. The packaging joints 81 are located on both sides of the packaging body 100 in the front-rear direction L of the absorbent article 1X, and extend along the width direction W. Since the outer edges of the absorbent article 1 in the width direction W and the packaging joints 81 are arranged perpendicular to each other, even if the absorbent article 1 moves within the packaging body 100, deformation of the absorbent core 30 caused by the outer edges of the absorbent core 30 hitting the packaging joints 81 can be suppressed. Preferably, the length in the front-rear direction L of the absorbent article (the absorbent article in a folded state) in the packaging body 100 is shorter than the distance in the front-rear direction between the packaging joints 81, and may be 80% to 90% of the distance in the front-rear direction between the packaging joints 81. This configuration can prevent the absorbent article 1X from moving excessively in the packaging body 100, while ensuring a gap between the packaging joints 81 and the absorbent article 1X, making it difficult for an external force from outside the packaging body 100 to be transmitted to the absorbent article.
[0051] 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]
