Description

  The present invention relates to an absorbent component.

  In an absorbent part such as a sanitary napkin having an absorbent body and a liquid-permeable surface sheet provided on the skin surface side of the absorbent body, a pair of side sheets are provided on both sides in the width direction on the skin surface side. The configuration is known. Patent Document 1 describes a configuration in which a side sheet and a surface sheet are bonded together with a bonding line, and a pocket that is opened when worn is formed between the bonding line and the inner edge of the side sheet. According to this configuration, the leak-proof effect by the pocket is stably maintained, and it is assumed that it is well curved and fits well to the user's body shape.

Japanese Patent No. 4484747

  However, in the configuration described in Patent Document 1, a joining line joining the top sheet and the side sheet is exposed on the skin surface side. FIG. 7 is a cross-sectional view for explaining the problems of the conventional sanitary napkin 100. The sanitary napkin 100 is configured by laminating a back sheet 120, an absorber 130, and a top sheet 140 in this order from the clothing side in the thickness direction T to the skin surface side. In the sanitary napkin 100, the inner end of the side sheet 150 in the width direction W overlaps with the side region of the absorbent body 130 in the width direction W, and is joined to the surface sheet 140 on the skin surface side of the surface sheet 140 by a joining line 152. Compressed and joined. Such a joining line 152 is formed by, for example, heat embossing, and the sheets are compressed to have a higher density than other portions.

  In such a configuration, body fluid such as menstrual blood is absorbed by the absorber 130, diffuses, and penetrates between fibers having a high density when reaching the position of the joining line 152 as indicated by an arrow in the figure. There is a fear. Further, since the body fluid collects on the joining line 152, the color of the body fluid is easily visible from the skin surface side. Therefore, although the body fluid does not actually leak, there is a fear that the part of the joining line 152 looks red, and the wearer may feel anxiety as if side leakage or the like has occurred.

  The present invention has been made in view of the above circumstances, and the purpose of the present invention is to suppress anxiety as if side leakage or the like given to the wearer occurs in the absorbent part provided with the side seat. Is to provide.

  According to the present invention, the absorbent article has a longitudinal direction and a width direction orthogonal to the longitudinal direction, and includes an absorbent body and a liquid-permeable surface sheet provided on the skin surface side of the absorbent body. A pair of side sheets provided on both outer sides in the width direction of the top sheet, and positions where the inner end portions in the width direction of the side sheets overlap side areas in the width direction of the absorber. A compression part that compresses and joins the surface sheet on the skin surface side of the surface sheet, and a cover sheet that covers the compression part from the skin surface side, wherein the compression part is the skin surface of the surface sheet. An absorbent article is provided that includes a cover sheet that is less visible from the side.

  ADVANTAGE OF THE INVENTION According to this invention, in the absorptive component provided with the side seat | sheet, the anxiety as if the side leak etc. which are given to a wearer have arisen can be suppressed.

It is a top view which shows an example of the structure which removed the cover sheet of the sanitary napkin in embodiment of this invention. It is AA 'sectional drawing of FIG. It is a cross-sectional schematic diagram corresponding to the AA 'cross-sectional view of FIG. It is a cross-sectional schematic diagram which shows the other example of the cover sheet of the sanitary napkin in embodiment of this invention. It is a cross-sectional schematic diagram which shows the other example of the cover sheet of the sanitary napkin in embodiment of this invention. It is sectional drawing for demonstrating the problem of the conventional sanitary napkin.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate. Further, the drawings are schematic, and the ratio of each dimension includes a case where it is different from the actual one.

  In this embodiment, a sanitary napkin will be described as an example of an absorbent article. However, the absorbent article of the present embodiment is not limited to a sanitary napkin. Also, so-called cage sheets (for example, panty liners) and disposable diapers are included.

  FIG. 1 is a plan view (skin side) showing an example of the configuration of a sanitary napkin 10 according to an embodiment of the present invention. FIG. 2 is a plan view (skin surface side) showing an example of a configuration in which the cover sheet 60 of the sanitary napkin 10 according to the embodiment of the present invention is removed. FIG. 3 is a cross-sectional view taken along line AA ′ of FIG.

  The sanitary napkin 10 has a longitudinal direction L, a width direction W orthogonal to the longitudinal direction L, and a thickness direction T orthogonal to the longitudinal direction L and the width direction W. The longitudinal direction L has a front side F that becomes the abdomen side of the wearer and a rear side R that becomes the back side of the wearer while the sanitary napkin 10 is being worn (during use). Thickness direction T has a skin surface side that is the side that comes into contact with the wearer's skin while wearing sanitary napkin 10 and a clothing side (non-skin side) that is the opposite side.

  The sanitary napkin 10 is a sheet-like member that is vertically long in plan view. The sanitary napkin 10 includes a liquid-impervious back sheet 20 (see FIG. 3), a liquid-absorbent absorber 30, and a liquid-permeable top sheet 40 from the clothing side in the thickness direction T to the skin surface side. It is configured to be stacked in this order.

  The absorber 30 absorbs and retains body fluids such as menstrual blood. The absorber 30 can have an absorptive core, a skin surface side sheet | seat, and a non-skin surface side sheet | seat, for example. The skin surface side sheet and the non-skin surface side sheet can be bonded to the skin surface side and the clothing side of the absorbent core with an adhesive or the like, respectively.

  An absorptive core, a skin surface side sheet | seat, and a non-skin surface side sheet | seat can be comprised with the material used as an absorber of a normal sanitary napkin. As an example, the absorbent core has cellulosic absorbent fibers that are liquid absorbent fibers and thermoplastic resin fibers, and these fibers can be in a mixed state. Liquid absorbent particles such as a super absorbent polymer (so-called SAP) may be added to the liquid absorbent fibers. As an example, the skin surface side sheet can be a flexible sheet excellent in liquid permeability such as a nonwoven fabric such as an air-through nonwoven fabric or a tissue paper. As an example, the non-skin side sheet can be a non-woven fabric such as SMS (spunbond / meltblown / spunbond) non-woven fabric or a flexible sheet such as tissue paper.

  The back sheet 20 suppresses that the bodily fluid which permeate | transmitted the top sheet 40 and was absorbed by the absorber 30 during wear of the sanitary napkin 10 exudes to the clothing side, such as underwear. The back sheet 20 can be made of a material used as a back sheet of a normal sanitary napkin. As an example, the back sheet 20 can be a liquid-impermeable flexible sheet of a resin film such as polyethylene (PE).

  The topsheet 40 is a member that comes into contact with the wearer's skin while the sanitary napkin 10 is worn, and allows the body fluid to permeate from the skin surface side in the thickness direction T to the clothing side and move to the absorbent body. The top sheet 40 can be made of a material used as a top sheet of a normal sanitary napkin. As an example, the surface sheet 40 can be a liquid-permeable flexible sheet of a nonwoven fabric such as an air-through nonwoven fabric.

  In addition, as shown in FIG. 1, the pressing part 42 formed by pressing the surface sheet 40 and the absorber 30 in the thickness direction T by embossing etc. is provided in the skin surface side of the surface sheet 40. ing. The pressing part 42 includes a linear pressing part along the longitudinal direction L, a dotted pressing part provided in a region surrounded by the linear pressing part, a pressing part having a bent shape such as a heart shape, and the like. . Here, the pressing part 42 refers to a part that prevents the surface sheet 40 and the absorber 30 from being integrally peeled off. Thereby, the surface sheet 40 and the absorber 30 are joined, and shape loss and twisting during wearing of the sanitary napkin 10 can be prevented. Moreover, the thickness of the sanitary napkin 10 can also be adjusted by providing the pressing part 42. Moreover, the flow of the bodily fluid absorbed in the absorber 30 etc. can also be controlled by providing the pressing part 42. The structure of the pressing part 42 is not restricted to the illustrated thing, For example, it can also be set as a grid | lattice shape, a dot shape, a wave shape, etc., It can be the same as that of what was provided in the normal sanitary napkin.

  Further, the sanitary napkin 10 includes a pair of side sheets 50 provided on both outer sides in the width direction W of the top sheet 40. Each side seat 50 includes a wing portion 50w extending outward in the width direction W, which is a fixing portion when the sanitary napkin 10 is attached to an undergarment (not shown) at a substantially central portion in the longitudinal direction L. .

  The side sheet 50 is a part that comes into contact with the wearer's skin while the sanitary napkin 10 is worn, and prevents body fluid flowing in the width direction W from leaking sideways on the top sheet 40. Further, the wing portion 50w of the side seat 50 is configured to be folded into a crotch portion of underwear such as sanitary shorts while the sanitary napkin 10 is worn. Although not shown, an adhesive portion for attaching and fixing the sanitary napkin 10 to an undergarment or the like while the sanitary napkin 10 is worn is provided on the clothing side of the back sheet 20 corresponding to the wing portion 50 w of the side sheet 50. It can be set as the provided structure.

  The side sheet 50 can be made of a material used as a side sheet of a normal sanitary napkin. As an example, the side sheet 50 can be composed of a spunbond nonwoven fabric or an SMS nonwoven fabric. The side sheet 50 is preferably hydrophobic or water repellent. The side sheet 50 can be made of, for example, the same material as that of the surface sheet 40 described above and subjected to hydrophobic treatment or water repellency treatment. By making the side sheet 50 hydrophobic or water-repellent, body fluid can be prevented from flowing outward.

  In the present embodiment, as shown in FIG. 3, the inner end of each side sheet 50 in the width direction W overlaps with the side region of the absorbent body 30 in the width direction W, and on the skin surface side of the top sheet 40. It is compressed and joined to the top sheet 40 by the compression unit 52. The compression part 52 can be formed by various methods of compressing and joining a plurality of sheets by heat embossing and ultrasonic processing. Here, the compression part 52 says the part which compressed and joined the surface sheet 40 and the side sheet 50. FIG.

  In addition, as shown in FIG. 2, the compression portion 52 is provided so as to continuously extend in the entire longitudinal direction L of the sanitary napkin 10.

  In another example, for example, the compression unit 52 may have a configuration in which a plurality of linear compression portions are arranged in the longitudinal direction L like a joining line described in Patent Document 1. Moreover, the compression part 52 may be formed so as to have an uneven pattern such as a lattice shape. The structure of the compression part 52 can be made to be the same as the various things provided in order to compress and join a surface sheet and a side sheet in a normal sanitary napkin.

  The planar shape of the back sheet 20 is substantially the same as the planar shape of the side sheet 50 and the top sheet 40 that are compressed and joined as described above. That is, the back sheet 20 has the same planar shape as that surrounded by the outer edge of the sanitary napkin 10 of FIG.

  Further, in the present embodiment, the sanitary napkin 10 includes a cover sheet 60 that covers the compression portion 52 from the skin surface side and makes the compression portion 52 difficult to see from the skin surface side of the topsheet 40. The cover sheet 60 corresponds to the hatched portion in FIG. Here, in addition to making the compression portion 52 completely invisible, for example, when the compression portion 52 is not provided with the cover sheet 60 such as a configuration in which the compression portion 52 is covered with a single opaque sheet, for example. It includes making it difficult to visually recognize. In FIG. 2, the cover sheet 60 is also indicated by a two-dot chain line in order to show the positional relationship between the compression unit 52 and the cover sheet 60. FIG. 2 corresponds to a cross-sectional view taken along the line BB ′ of FIG. 4 described later, and shows the sanitary napkin 10 from the skin surface side.

  The cover sheet 60 can be made of, for example, the same material as the side sheet 50 described above. As an example, the cover sheet 60 can be composed of, for example, a spunbond nonwoven fabric or an SMS nonwoven fabric. Like the side sheet 50, the cover sheet 60 is preferably hydrophobic or water repellent. By making the cover sheet 60 hydrophobic or water-repellent, it is possible to make it difficult for body fluid to migrate from the topsheet 40 or the sidesheet 50 and to prevent body fluid from being exposed to the skin surface.

  In this Embodiment, as shown in FIG.1 and FIG.3, a bodily fluid is absorbed during wearing of the sanitary napkin 10 by covering the compression part 52 which joins the surface sheet 40 and the side sheet 50 with the cover sheet 60. Even if it is drawn into the compression unit 52 via the body 30, the state where the body fluid is absorbed by the compression unit 52 is concealed and is difficult to visually recognize from the skin surface side. Therefore, anxiety such as side leakage can be suppressed.

  Moreover, since the compression part 52 is compressing sheets, it is easy to feel hardness and rigid intuition, and there was a possibility that a wearer may feel uncomfortable while wearing. However, since the cover sheet 60 covers the compression portion 52, the compression portion 52 does not directly touch the skin, so that the intuition of rigidity can be alleviated and the uncomfortable feeling can be suppressed while the sanitary napkin 10 is worn. . In addition, the body fluid absorbed by the absorbent body 30 is drawn into the compression section 52, so that the compression section 52 may feel wet when worn. However, by providing the cover sheet 60, the wet feeling during wearing of the sanitary napkin 10 can be further reduced.

  As described above, according to the sanitary napkin 10 in the present embodiment, it is possible to achieve both concealment and reduction in discomfort.

  Next, the configuration of the cover sheet 60 will be specifically described. FIG. 4 is a schematic cross-sectional view corresponding to the AA ′ cross-sectional view of FIG. 1. FIG. 4 corresponds to FIG. 3, but is a diagram schematically showing the configuration of FIG. 3.

  The cover sheet 60 may be configured such that a plurality of sheets (first sheet 60b and second sheet 60c) are stacked on the side sheet 50. By making the cover sheet 60 have a structure in which a plurality of sheets are laminated in this way, the concealing property of the compression section 52 can be enhanced. Therefore, the state where the body fluid is absorbed by the compression unit 52 can be further prevented from being seen from the surface of the cover sheet 60. The number of sheets to be stacked can be set arbitrarily, and can be set as appropriate in consideration of the concealing property with respect to the compression portion 52 and a reduction in uncomfortable feeling during wearing.

  Moreover, it can be set as the structure by which the adhesive bond layer 64 comprised with the lipophilic adhesive agent was provided between several sheets, ie, between the 1st sheet | seat 60b and the 2nd sheet | seat 60c. By providing the adhesive layer 64 between the plurality of sheets in this manner, even if the body fluid adheres to the first sheet 60b, the lipophilic adhesive prevents the body fluid from being transferred. It is possible to further prevent the absorbed body fluid from leaking to the surface of the cover sheet 60.

  Here, the adhesive layer 64 can be a plurality of adhesive layers 64a, an adhesive layer 64b, and an adhesive layer 64c provided along the longitudinal direction L on the first sheet 60b. The adhesive layer 64a to the adhesive layer 64c can be configured to be spaced apart in the width direction W. By adopting such a configuration, a plurality of sheets can be loosened, and the cover sheet 60 has a degree of freedom. Therefore, it is possible to reduce a sense of incongruity at the time of contact with the body being worn. However, in another example, the adhesive layer 64 may be a layer continuously provided in the width direction W, and the adhesive layer 64 includes only a part of the adhesive layer 64a to the adhesive layer 64c. Also good.

  In addition, the second sheet 60c, which is the uppermost sheet among the plurality of sheets constituting the cover sheet 60, can be configured to be connected to the lower first sheet 60b outside in the width direction W. . By setting it as such a structure, since a cut end does not appear in the outer side edge part of the width direction W of the cover sheet 60, the touch can be improved. When three or more layers are stacked on the side sheet 50, the uppermost sheet can be connected to any one of the lower sheets on the outside in the width direction W. In this case as well, the cover sheet 60 can be configured such that no cut ends appear at the outer end in the width direction W.

  Further, an adhesive layer 54 composed of a lipophilic adhesive is provided between the top sheet 40 and the side sheet 50, and the adhesive layer 54 is compressed and joined by the compression portion 52. be able to.

  By disposing the adhesive layer 54 between the top sheet 40 and the side sheet 50 in the compression unit 52, the transfer of body fluid from the top sheet 40 to the side sheet 50 is less likely to occur. Further, the bonding strength between the topsheet 40 and the sidesheet 50 by the compression unit 52 can be increased, and the sidesheet 50 can be made difficult to peel from the topsheet 40. Furthermore, since the adhesive layer 54 is also compressed and joined by the compression part 52, the adhesive enters between the fibers of the compression part 52, so that voids between the fibers are reduced and it is difficult to retain body fluid. As a result, it is difficult for body fluids to collect.

  Note that the cover sheet 60 is folded from the second sheet 60 c to the clothing side, extends to the outside in the width direction W on the clothing side of the side sheet 50, and is joined to the top sheet 40 by the compression unit 52. 60a may be included. In the example shown in FIG. 4, the side sheet 50 is configured to be bonded to the surface sheet 40 via the bonding end portion 60 a of the cover sheet 60, and the side sheet 50 is directly bonded to the surface sheet 40. is not. However, in this case as well, the transfer of body fluid to the side sheet 50 can be made difficult to occur, and the bonding strength can be increased.

  Further, the cover sheet 60 (first sheet 60 b) can be configured to be joined to the side sheet 50 by the adhesive layer 62 outside the compression portion 52 in the width direction W. By setting it as such a structure, since the outer side edge part of the width direction W of the cover sheet 60 is joined to the side sheet 50, the lift etc. from the surface sheet 40 of the cover sheet 60 can be suppressed, and touch is improved. can do.

  Further, the cover sheet 60 has a portion joined to the side sheet 50 (a portion joined by the adhesive layer 62 in the example shown in FIG. 4), but a portion corresponding to the compression portion 52 on the side sheet 50. Then, it can be set as the structure which is not joined to the side sheet | seat 50. FIG. Here, “not joined” means that no adhesive layer is provided between the side sheet 50 and the cover sheet 60 on the compression part 52.

  By setting it as such a structure, since the clearance gap 61 is made between the compression part 52 and the cover sheet 60 (1st sheet | seat 60b), rigidity is reduced and the touch can be improved. In addition, since a gap 61 is formed between the compression unit 52 and the first sheet 60b, body fluid drawn into the compression unit 52 is prevented from being transferred to the cover sheet 60, and anxiety of side leakage can be prevented. it can.

  However, in another example, an adhesive layer made of a lipophilic adhesive may be provided between the side sheet 50 and the cover sheet 60 (first sheet 60b) on the compression unit 52. Even in such a configuration, it is possible to make it difficult for the body fluid drawn into the compression unit 52 to shift to the cover sheet 60.

  Further, as described above, the cover sheet 60 is a folded portion that extends inward in the width direction W from the joint end portion 60a that is a portion that is compressed and joined by the compression portion 52 and is bent toward the skin surface side. The compression part 52 can be configured to be covered with a second sheet 60c that extends from the folded part to the outside in the width direction W. Here, the folded portion can form the inner end in the width direction W of the cover sheet 60.

  As described above, the cover sheet 60 is folded inward in the width direction W, so that even if the cover sheet 60 is floating, the compression portion 52 cannot be seen from the inside, so that anxiety such as side leakage is further suppressed. be able to. In addition, since the cover sheet 60 has a structure that is folded back in the width direction W, a cut end does not appear at the inner end portion of the cover sheet 60 in the width direction W, so that the touch can be improved.

  Further, by adopting such a configuration, the compression portion 52 and the cover sheet are combined with the above-described configuration in which the cover sheet 60 is not joined to the side sheet 50 in the portion corresponding to the compression portion 52 on the side sheet 50. It becomes easy to form the clearance gap 61 between 60 (1st sheet | seat 60b).

  In addition, the adhesive layer 54, the adhesive layer 64 (64a to 64c), the adhesive layer 62, and the like described above can be configured with an oleophilic sealing hot-melt adhesive or the like. As the hot melt adhesive, a material used as a hot melt adhesive for sealing a normal sanitary napkin can be used. As an example, a rubber-based hot melt adhesive can be used.

  Further, the cover sheet 60 can be formed integrally with the side sheet 50, and is connected to the side sheet 50 only through the side sheet 50 and the adhesive layer (the adhesive layer 62 in the example shown in FIG. 4). Can be configured. That is, the cover sheet 60 can be configured so as not to be joined to the side sheet 50 by the compression unit or the like on the side sheet 50. By adopting such a configuration, it is possible to prevent body fluid from leaking from a separately provided compression section or the like.

  Moreover, the cover sheet 60 can be comprised with the material same as the side sheet 50, and can be set as the structure connected on the side sheet 50 only through the side sheet 50 and the adhesive bond layer. With such a configuration, the cover sheet 60 and the side sheet 50 can be easily joined with an adhesive or the like, and there is no need to separately join the cover sheet 60 and the side sheet 50 with a compression unit or the like. Therefore, it is possible to prevent body fluid from leaking from a separately provided compression section or the like.

  In the configuration shown in FIG. 4, the cover sheet 60 and the side sheet 50 have a configuration in which one sheet is folded and stacked, and one end side of the one sheet is a joining end portion 60 a and the other end side is a side sheet. 50.

  Furthermore, the cover sheet 60 can be configured to cover the entire compression unit 52 in the longitudinal direction L. By setting it as such a structure, since the compression part 52 is covered with the cover sheet 60 in any part of the longitudinal direction L, it can respond to a side leak not only in the center part of the absorber 30 but in the front-back direction.

  Furthermore, the cover sheet 60 can be configured to be wider than the width of the compression unit 52 in the width direction W. Thereby, since the compression part 52 is covered in any part of the width direction W, it can respond also to a side leak.

  Although schematically shown in FIG. 4, actually, the folding position between the joining end portion 60 a and the second sheet 60 c and the folding position between the first sheet 60 b and the side sheet 50 are used. Can be at substantially equal positions in the width direction W. In other words, in the configuration shown in FIG. 1, the inner end of the side sheet 50 in the width direction W can be set to a position substantially equal to the inner end of the cover sheet 60 in the width direction W. Further, the first sheet 60b and the second sheet 60c can be formed to have substantially the same width in the width direction W.

  As described above, according to the sanitary napkin 10 of the present embodiment, in the configuration in which the side seat 50 is provided, it is possible to suppress anxiety as if side leakage or the like given to the wearer has occurred.

  Moreover, since the compression part 52 does not touch skin directly, rigid intuition can be eased with the cover sheet 60, and the discomfort during wearing the sanitary napkin 10 can be suppressed. Furthermore, by providing the cover sheet 60, the wet feeling during wearing of the sanitary napkin 10 can be further reduced. As described above, according to the sanitary napkin 10 in the present embodiment, it is possible to achieve both concealment and reduction in discomfort.

Next, a modified example of the cover sheet 60 in the present embodiment will be described.
(Modification 1)
In FIG. 4, an example in which the cover sheet 60 is formed integrally with the side sheet 50 is shown, but the cover sheet 60 may be configured separately from the side sheet 50. FIG. 5 is a schematic cross-sectional view showing another example of the cover sheet 60 of the sanitary napkin 10 according to the present embodiment.

  Further, the cover sheet 60 can be constituted by a single sheet provided on the compression unit 52 so as to cover the compression unit 52. In this case, the cover sheet 60 can be made of the same material as the side sheet 50, or can be made of a different material.

  Moreover, the cover sheet 60 can be made into the structure joined to the side sheet 50 by the adhesive bond layer 66 comprised with the lipophilic adhesive agent. The adhesive layer 66 can be made of the same material as the adhesive layer 54 described above. Further, the adhesive layer 66 can be configured to be provided on the compression portion 52 as shown in the figure. By setting it as such a structure, the transfer to the cover sheet 60 of the bodily fluid drawn in to the compression part 52 can be made hard to occur.

  As another example, the cover sheet 60 is joined to the side sheet 50 by providing the adhesive layer 66 not on the compression part 52 but on the inner side and the outer side in the width direction W where the compression part 52 is provided. You can also By setting it as such a structure, the clearance gap 61 as shown in FIG. 4 can be formed between the compression part 52 and the cover sheet 60, rigidity can be reduced and the touch can be improved. Further, by forming a gap between the compression unit 52 and the cover sheet 60, body fluid drawn into the compression unit 52 can be prevented from moving to the cover sheet 60, and anxiety of side leakage can be eliminated. it can.

  Also in this example, the plan view of the cover sheet 60 can be the same as that shown in FIG.

Even in such a configuration, even when body fluid is drawn into the compression unit 52 via the absorbent body 30 while the sanitary napkin 10 is worn, the state in which the body fluid is absorbed by the compression unit 52 is visually recognized from the skin surface side. It becomes difficult to do. Therefore, anxiety such as side leakage can be suppressed.
(Modification 2)
FIG. 6 is a schematic cross-sectional view showing still another example of the cover sheet 60 of the sanitary napkin 10 in the present embodiment.

  In this example, as in the example shown in FIG. 4, the cover sheet 60 is formed integrally with the side sheet 50, but the cover sheet 60 is a single layer provided on the compression unit 52 so as to cover the compression unit 52. It can be set as the structure containing a sheet | seat. Specifically, the cover sheet 60 may be configured to be folded back to the skin surface side at the inner end portion in the width direction W of the side sheet 50 and extend to the outside in the width direction W. Further, the boundary portion between the side sheet 50 and the cover sheet 60 can be configured to be joined by the top sheet 40 and the compression unit 52. Moreover, the cover sheet 60 can be made into the structure joined by the adhesive layer 68 comprised by the side sheet 50 and the lipophilic adhesive agent in the width direction W outer side on the side sheet 50. FIG. The adhesive layer 68 can be made of the same material as the adhesive layer 54 described above.

  Also in this example, the plan view of the cover sheet 60 can be the same as that shown in FIG.

  Even if it is set as such a structure, the effect similar to the sanitary napkin 10 demonstrated with reference to FIG. 5 is acquired. Further, by adopting a structure in which the cover sheet 60 is folded inward in the width direction W, even if the cover sheet 60 is floating, the compression portion 52 is not visible from the inside, thereby further reducing anxiety such as side leakage. Can do. In addition, since the cover sheet 60 has a structure that is folded back in the width direction W, a cut end does not appear at the inner end portion of the cover sheet 60 in the width direction W, so that the touch can be improved.

  In the above description, configurations not related to the features of the present embodiment are omitted. For example, the sanitary napkin 10 has various configurations that the normal sanitary napkin 10 has, such as an adhesive portion provided on the clothing side of the back sheet 20 in order to detachably attach the sanitary napkin 10 to an undergarment (not shown).
