Description

  The present invention relates to absorbent articles individually packaged with a packaging sheet.

  For example, absorbent articles such as sanitary napkins may be individually packaged with packaging sheets. Patent Document 1 discloses an absorbent article individually packaged by a packaging sheet.

  The absorbent article described in Patent Document 1 has a top sheet, a back sheet, and an absorber between the top sheet and the back sheet. Further, the absorbent article has a pair of wings and a pair of hip flaps. The pair of wings extends outward in the width direction with respect to the absorber, and is folded back to the non-skin surface side of the underwear when attached to the underwear. The pair of wings is rearward of the pair of wings and bulges outward in the width direction. The wing has a wing adhesive layer to secure the wing to the underwear. The hip flap has a hip flap adhesive layer for fixing the hip flap to the underwear.

  The absorbent article is folded together with the packaging sheet while being placed on the packaging sheet. As a result, the absorbent article is in a state of being wrapped in the packaging sheet. In the state where the folded absorbent article is expanded in the longitudinal direction, the wings and the hip flaps are folded back to the skin surface side of the absorbent article (see FIG. 2 of Patent Document 1). In this state, one sheet of release paper covers both the wing adhesive layer and the hip flap adhesive layer. The release paper is provided to prevent the adhesive force of the pressure-sensitive adhesive layer from decreasing before the absorbent article is used.

JP, 2011-45608, A

  A user attaches an absorbent article such as a sanitary napkin to underwear by the following procedure. First, the user opens the packaging sheet, develops the absorbent article, and peels the release paper from the absorbent article. Next, the center of the pair of wings in the longitudinal direction of the absorbent article is attached to a position substantially corresponding to the crotch of the undergarment, specifically, a position having the narrowest width of the undergarment. Then, the user attaches the rear region of the absorbent article, that is, the region having the hip flap, to the region behind the crotch of the undergarment.

  The inventor of the present application has found a problem that a region behind the absorbent article may be attached to the shorts while being shifted in the width direction. That is, the user does not have a reference for determining whether the center in the width direction of the rear region of the absorbent article deviates from the center position in the width direction of the underwear, and thus positioning in the width direction is difficult.

  In particular, when only the wings are positioned on the undergarment, it is difficult to determine the widthwise deviation and the angular deviation of the absorbent article. The user may notice that the area behind the absorbent article is offset in the width direction only when the entire absorbent article is attached to the underwear. This is because the slight deviation when the wing is fixed to the underwear increases as it goes toward the rear of the absorbent article.

Here, in the absorbent article described in Patent Document 1, when one release paper is peeled off, both the wing adhesive layer and the hip flap adhesive layer are exposed. Therefore, it is difficult to correct the position of the absorbent article in the width direction while the absorbent article is being attached to the underwear. In particular, when the misalignment of the absorbent article is noticed only when the entire absorbent article is attached to the underwear, the user needs to peel off the adhesive layer fixed to the underwear from the underwear. In this case, the adhesive strength of the pressure-sensitive adhesive layer may decrease.
Therefore, there is a demand for an absorbent article capable of suppressing positional deviation when attached to underwear.

  The absorbent article according to one aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, an absorber, a pair of wings extending outward from the absorber in the width direction, and more than the wings. In the rear, a pair of hip flaps bulging outward in the width direction, a pair of wing adhesive layers provided on a surface facing the underwear of the pair of wings, and a surface facing the underwear of the pair of hip flaps. With the pair of hip flap adhesive layers provided and the pair of wings folded to the skin side, the wing release sheet covering the pair of wing adhesive layers and the pair of hip flaps folded to the skin side. And a hip flap release sheet that covers the pair of hip flap adhesive layers, the hip flap release sheet comprising: In the away from the wing release sheet, the absorbent article is located at the center of the absorbent article in the width direction, has an identifying portion extending in the front-rear direction, at least a part of the identifying portion The hip flap release sheet extends forward of the front end of the release sheet.

It is a top view of the absorbent article in a 1st embodiment. It is a top view of the absorbent article seen from the opposite side to FIG. It is a top view of the absorptive article individually wrapped with the packaging sheet. FIG. 3 is a plan view of the absorbent article according to the first embodiment in which the wings and the hip flaps are folded. It is a schematic diagram for demonstrating the procedure of attaching an absorbent article to underwear. It is a top view of the absorbent article in a 2nd embodiment. It is a top view of the absorbent article which concerns on 2nd Embodiment with which the wing and the hip flap were folded. It is sectional drawing of the absorbent article along the AA line of FIG.

(1) Outline of Embodiments At least the following matters will be made clear by the present specification and the description of the accompanying drawings.

  The absorbent article according to one aspect includes a front-rear direction, a width direction orthogonal to the front-rear direction, an absorber, a pair of wings extending outward from the absorber in the width direction, and more than the wings. In the rear, a pair of hip flaps bulging outward in the width direction, a pair of wing adhesive layers provided on a surface facing the underwear of the pair of wings, and a surface facing the underwear of the pair of hip flaps. With the pair of hip flap adhesive layers provided and the pair of wings folded to the skin side, the wing release sheet covering the pair of wing adhesive layers and the pair of hip flaps folded to the skin side. And a hip flap release sheet that covers the pair of hip flap adhesive layers, the hip flap release sheet comprising: In the away from the wing release sheet, the absorbent article is located at the center of the absorbent article in the width direction, has an identifying portion extending in the front-rear direction, at least a part of the identifying portion The hip flap release sheet extends forward of the front end of the release sheet.

  With the absorbent article according to this aspect, the user can attach the absorbent article to the underwear by the following procedure. First, the user opens the packaging sheet, develops the absorbent article, and peels the wing release sheet from the absorbent article. Next, the center of the pair of wings in the front-rear direction is attached to a position substantially corresponding to the crotch of the underwear, specifically, a position having the narrowest width of the underwear. Next, the rear region of the absorbent article is attached to the undergarment so that the identification portion coincides with the center of the underwear in the width direction. Thereby, it is possible to prevent the rear side region of the absorbent article from being displaced in the width direction with respect to the underwear.

  Further, since the hip flap release sheet is separated from the wing release sheet, the wings can be attached to the underwear in a state where the pair of hip flaps are folded to the skin surface side. Therefore, the hip flap release sheet can be peeled off and the hip flap can be secured to the undergarment after the wings are attached to the undergarment and then the back area of the absorbent article is attached to the undergarment. In this case, it is possible to prevent the hip flap adhesive layer from unexpectedly adhering to an unexpected place of the absorbent article or underwear while the absorbent article is being worn.

  According to a preferred aspect, the identification unit has a tactile sensation different from a region around the identification unit. This allows the user to recognize the identification unit by touch. Therefore, even when the user attaches the absorbent article to the underwear in a dark place such as a private room of a toilet, the user can determine the center position of the absorbent article in the width direction by touch. Therefore, even in a dark place, it is possible to prevent the rear region of the absorbent article from being displaced in the width direction with respect to the underwear.

  According to a preferred aspect, the absorbent article has a skin surface sheet provided on the skin surface side of the absorber, and the identification portion is a print layer provided on the skin surface sheet, or at least the skin. It is composed of a squeezing section applied to the face sheet. According to this aspect, the identification portion can be easily formed by the printing layer or the pressing portion.

  According to a preferred aspect, the identification part is provided on a low basis weight region lower than the basis weight of the absorbent core around the identification part, and is provided on the non-skin surface side of the absorption core, and the skin surface of the absorption core. And a colored sheet having a color different from that of the sheet provided on the side, and the low basis weight region is located at the center of the absorbent article in the width direction and extends in the front-rear direction.

  The colored sheet provided on the non-skin side of the absorbent core can be seen through in the low basis weight area. Therefore, when the absorbent article is viewed from the skin side, the low basis weight area extending in the front-rear direction at the center of the absorbent article in the width direction looks different in color from the other areas. In this way, the identification portion can be configured by the colored sheet and the low basis weight area.

  According to a preferred aspect, the identifying portion is located in a region that does not overlap the pair of hip flaps in a state where the pair of hip flaps are folded to the skin surface side. Accordingly, the identification section is not covered with the pair of hip flaps, and thus the user can easily recognize the identification section.

  According to a preferred aspect, the absorbent article has a fold line that passes through the hip flap and extends along the width direction, and at least a part of the identifying portion is located on the front side of the fold line.

  The area behind the fold line that passes through the hip flap is likely to bend in the direction of rising to the skin side due to the crease. Therefore, if the identification part exists behind the fold line passing through the hip flap, the area behind the fold line passing through the hip flap bends in the direction of rising, and the identification part becomes difficult for the user to see. I will end up.

  In this aspect, since the identification portion is present in front of the fold line passing through the hip flap, the user can easily recognize the identification portion while wearing the absorbent article.

  According to a preferred aspect, the absorbent article has a main body adhesive layer provided in a region overlapping with the absorber in the thickness direction, and the main body adhesive layer is provided intermittently in the front-rear direction. .

  If the main body adhesive layer continuously extends in the front-rear direction, even if the attachment angle or the position in the width direction of the absorbent article is slightly deviated, it is difficult to correct the deviation during the attachment of the absorbent article. In this aspect, since the main body adhesive layer is provided intermittently in the front-rear direction, while adjusting the position in the width direction of the absorbent article in the region where the main body adhesive layer does not exist, the absorbability from the front side to the rear side is improved. The article can be worn on underwear.

  According to a preferred aspect, at least a part of the non-adhesive region located between the main body adhesive layers in the front-rear direction is the center of the wing in the front-rear direction and the center of the hip flap in the front-rear direction. Located in between.

  Since the non-stick area is between the center of the wing and the center of the hip flap, the user can adjust the widthwise position of the absorbent article in the area between the center of the wing and the center of the hip flap. . This can eliminate the positional deviation in the width direction of the area behind the absorbent article.

  According to a preferred aspect, at least a part of the non-adhesive region located between the main body adhesive layers in the front-rear direction is located between the wing release sheet and the hip flap release sheet.

  Since the identification portion extends forward from the front end portion of the hip flap release sheet, the non-adhesive region is located near the identification portion. This allows the user to easily adjust the position of the absorbent article in the width direction in the non-adhesive region when recognizing that the position of the absorbent article in the width direction is displaced by the identification unit.

  According to a preferred aspect, at least in a region in front of the hip flap release sheet, the interval between the pair of hip flaps folded to the skin surface side becomes narrower from the front to the rear.

  Thereby, in a state where the pair of hip flaps are folded to the skin surface side, the eyes of the user are likely to be directed toward the center of the absorbent article in the width direction from the front side of the hip flap toward the rear side. Therefore, the user can naturally find the identification part, and when wearing the absorbent article on the underwear, it becomes easy to try to wear the absorbent article so that the identification part is located at the center of the underwear in the width direction. .

(2) Configuration of Absorbent Article Hereinafter, the absorbent article according to the first embodiment will be described with reference to the drawings. The absorbent article may be any absorbent article such as a panty liner (sheet of vaginal discharge), a sanitary napkin, an incontinence pad, a disposable diaper, or the like. In the following embodiments, a disposable sanitary napkin will be described as an example of an absorbent article.

  In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the respective dimensions may be different from the actual ones. Therefore, specific dimensions should be determined in consideration of the following description. Further, the drawings may include portions having different dimensional relationships and ratios.

  FIG. 1 is a plan view of an absorbent article according to an embodiment. FIG. 2 is a rear view of the absorbent article. The absorbent article 1 has a longitudinal direction L and a width direction W orthogonal to each other. Below, the side facing the wearer's skin during use is referred to as the “skin facing surface side” or “skin surface side”. Further, the side opposite to the skin-facing surface side during use, that is, the side facing away from the wearer's skin is referred to as the “non-skin facing surface side” or the “non-skin surface side”.

  The absorbent article 1 has a crotch region S1, a front side region S2, and a rear side region S3. The crotch region S1 is a region facing the excretory opening of the wearer, for example, the vaginal opening. When the absorbent article 1 is worn on the undergarment, the crotch region S1 is a region which is arranged at the crotch portion of the underwear and is arranged between the wearer's legs. The front area S2 is located on the front side of the crotch area S1. The front edge of the front area S2 defines the front edge of the absorbent article 1. The rear region S3 is located rearward of the crotch region S1. The rear edge of the rear region S3 defines the rear edge of the absorbent article 1.

  The absorbent article 1 has a wing 3 and a hip flap 4. The wings 3 and the hip flaps 4 extend outward in the width direction W from the outer edges of the absorber 30 in the crotch region S1. The hip flap 4 is provided behind the wings 3. The wings 3 are provided in the crotch region S1. The front end edge of the wing 3 is defined by the root of the wing 3, and corresponds to the portion located on the front side of the two most recessed portions inward in the width direction W. The front edge of the wing 3 defines the boundary between the crotch region S1 and the front side region S2. The rear end edge of the wing 3 is defined by the root of the wing 3, and corresponds to the portion located on the rear side of the two innermost recessed portions in the width direction W. The rear edge of the wing 3 defines the boundary between the crotch region S1 and the rear side region S3. The center of the crotch region S1 in the longitudinal direction L may coincide with the center of the wing in the longitudinal direction. The hip flap 4 is provided in the rear side area S3.

  The absorbent article 1 includes a skin sheet 10, a non-skin sheet 20, and an absorber 30. The skin sheet 10 is provided closer to the skin-facing surface than the absorber 30. The skin sheet 10 may include a top sheet 11 and side sheets 12. The top sheet 11 is a liquid-permeable sheet that allows liquid such as body fluid to pass therethrough. The side sheet 12 covers an outer edge of the top sheet 11 in the width direction W and extends outward in the width direction W with respect to the top sheet 11. The non-skin surface sheet 20 is a liquid impermeable sheet. The non-skin surface sheet 20 is provided on the non-skin facing surface side of the absorber 30.

  The non-skin surface sheet 20 is provided with an adhesive layer for fixing the absorbent article 1 to underwear. The adhesive layer is provided on the main body adhesive layer 60 arranged in a region overlapping with the absorber 30, the wing adhesive layer 63 arranged on the surface facing the underwear of the wing 3, and the surface facing the underwear of the hip flap 4. And the hip flap adhesive layer 64. The main body adhesive layer 60 includes at least a first main body adhesive layer 61 provided in the crotch region S1 and at least a second main body adhesive layer 62 provided in the rear side region S3.

  The absorber 30 is provided between the skin surface sheet 10 and the non-skin surface sheet 20. The absorber 30 is arranged at least in the crotch region S1 and the rear side region S3. The absorber 30 includes an absorbent core made of an absorbent material that absorbs liquid, and a cover sheet that wraps the absorbent core.

  The absorbent article 1 has a central compressed portion 81 at least in the rear region S3. The central compression portion 81 is formed by compressing at least the top sheet 11 that is the skin sheet 10 and the absorber 30 in the thickness direction. The central compressed portion 81 is located at the center of the absorbent article 1 in the width direction W and extends in the front-rear direction L.

  The absorbent article 1 may have a width compression part 82 and a longitudinal compression part 83 in the rear side region S3, in addition to the central compression part 81. The width compression part 82 and the longitudinal compression part 83 should just be formed by compressing at least the absorber 30 in the thickness direction. In the present embodiment, the width compression part 82 and the longitudinal compression part 83 are formed in the top sheet 11 and the absorber 30 in the rear side region S3.

  The central compression part 81, the width compression part 82, and / or the longitudinal compression part 83 are configured by an aggregate of a plurality of dot-shaped compression parts. Instead of this, the central compression portion 81, the width compression portion 82, and the longitudinal compression portion 83 may be configured by compression portions that continuously extend in a linear shape.

  The central compressed portion 81 extends in the longitudinal direction L and constitutes a deformation base point that extends in the longitudinal direction L when worn. When the crotch region is sandwiched between the wearer's legs when worn, a force is applied to the rear region S3 from the outer side in the width direction to the inner side in the width direction. By this force, the rear side region S3 of the absorbent article projects toward the gluteal cleft of the wearer at the central compressed portion 81. Therefore, the fit of the absorbent article to the wearer's body can be improved.

  The width squeezing portion 82 extends outward in the width direction W from the central squeezing portion 81, and constitutes a deformation base point that extends in the width direction W when worn. The width squeezing section 82 extends from the outer side in the width direction W to the inner side in the width direction W from the front side toward the rear side. The width squeezing portions 82 each function as a deformation base point extending in the width direction. Therefore, the back side region S3 is easily deformed along the roundness along the front-back direction of the body, and the absorbent article is more easily fitted to the buttocks.

  The pair of longitudinal compression portions 83 extend in the longitudinal direction L on both outer sides of the central compression portion 81 and the width compression portion 82 in the width direction W, and constitute a deformation base point that extends in the longitudinal direction L when worn. Thereby, when a force is applied to the rear side region S3 from the outer side in the width direction to the inner side in the width direction, the region between the pair of longitudinal compression portions 83 is more likely to project toward the gluteal cleft of the wearer. . Therefore, the fit of the absorbent article to the wearer's body can be further improved.

  The absorbent article 1 may be individually wrapped in a folded state. FIG. 3 shows the absorbent article 1 individually wrapped by the packaging sheet 100. FIG. 4 is a plan view of the absorbent article 1 with the wings 3 and the hip flaps 4 folded. FIG. 4 shows the absorbent article 1 with the packaging sheet 100 opened.

  The absorbent article 1 has two front and rear folding lines FL extending along the front-rear direction L and at least two width folding lines F1 and F2 extending along the width direction W. In the packaged state, the pair of wings 3 and the pair of hip flaps 4 are folded back to the skin surface side with the front-back folding line FL as a reference. The front-to-back folding line FL may be arranged outside the absorber 30 in the width direction W.

  The at least two width folding lines include a first width folding line F1 and a second width folding line F2. The first width folding line F1 passes through the hip flap 4 in the rear area S3. The second width folding line F2 passes through the crotch region S1 or the front side region S2. In the present embodiment, the second width folding line F2 passes through the front side area S2.

  The absorbent article 1 folded along the front-back fold line FL is further folded along with the wrapping sheet 100 along the first width fold line F1 and the second width fold line F2 to the skin surface side while being placed on the wrapping sheet 100. . Thereby, as shown in FIG. 3, the absorbent article 1 is in a state of being wrapped with the packaging sheet 100. The wrapping sheets 100 that are overlapped by being folded are joined to each other at both side portions in the width direction (portions located on both outer sides in the lateral direction in FIG. 3), and the unsealed portion of the wrapping sheet 100 is joined to the joining tape 102. The packaging sheet 100 is prevented from opening spontaneously by sealing with such sealing means.

  The absorbent article 1 has a wing release sheet 73 that covers the pair of wing adhesive layers 63 in a state where the pair of wings 3 are folded to the skin surface side. The absorbent article 1 also has a hip flap release sheet 74 that covers the pair of hip flap adhesive layers 64 in a state where the pair of hip flaps 4 are folded to the skin surface side. The hip flap release sheet 74 is separated from the wing release sheet 73 in the front-rear direction L.

  At least a part of the central compression portion 81 extends forward from the front end of the hip flap release sheet 74. In the first embodiment, the central squeezing section 81 constitutes the identifying section 80 extending in the front-rear direction L.

  With the absorbent article according to this aspect, the user can attach the absorbent article to the underwear by the following procedure. First, the user opens the packaging sheet 100, develops the absorbent article, and peels the wing release sheet 73 from the absorbent article 1. Next, the center of the pair of wings 3 in the front-rear direction L is attached to a position substantially corresponding to the crotch of the underwear S, specifically, a position having the narrowest width of the underwear S (see FIG. 5). Next, the rear region S3 of the absorbent article 1 is attached to the underwear so that the identification portion 80 coincides with the center of the underwear in the width direction W. This can prevent the rear area S3 of the absorbent article from being displaced in the width direction W with respect to the underwear.

  Further, since the hip flap release sheet 74 is separated from the wing release sheet 73, the wing 3 can be attached to the underwear with the pair of hip flaps 4 folded to the skin surface side. Therefore, after attaching the wing 3 to the underwear and then attaching the rear side region S3 of the absorbent article 1 to the underwear, the hip flap release sheet 74 can be peeled off and the hip flap 4 can be fixed to the underwear. In this case, it is possible to prevent the hip flap adhesive layer 64 from unexpectedly adhering to an unexpected location of the absorbent article 1 or the underwear S during the wearing of the absorbent article 1.

  In the present embodiment, the identification unit 80 is composed of the central compression unit 81. However, the identification unit 80 is not limited to this configuration. For example, the identification unit 80 may be configured by a print layer provided on the skin surface sheet 10. Even in this case, as described above, it is possible to prevent the rear side region S3 of the absorbent article from being displaced in the width direction W with respect to the underwear.

  When the identification portion 80 is configured by the printed layer provided on the skin sheet 10, or at least the compressed portion applied to the skin sheet, there is an advantage that the identification portion 80 can be easily formed at the time of manufacturing. .

  Preferably, the identification unit 80 has a different tactile sensation than the area around the identification unit 80. As a result, the user can recognize the identification unit 80 by touch. Therefore, even when the absorbent article 1 is attached to the underwear S in a dark place such as a private room of a toilet, the user can determine the center position of the absorbent article 1 in the width direction W by the touch. . Therefore, even in a dark place, it is possible to prevent the rear area S3 of the absorbent article 1 from being displaced in the width direction W with respect to the underwear.

  The identification unit 80 is preferably located in a region that does not overlap the pair of hip flaps 4 when the pair of hip flaps 4 are folded to the skin surface side. As a result, the identification unit 80 is not covered by the pair of hip flaps 4, so that the user can easily recognize the identification unit 80.

  Further, it is preferable that at least a part of the identification portion 80 is located in front of the first width folding line F1 passing through the hip flap 4. A region on the rear side of the first width folding line F1 passing through the hip flap 4 is likely to bend in a direction in which it floats up to the skin surface side due to a crease. Therefore, if the identification portion 80 exists behind the first width folding line F1 that passes through the hip flap 4, the area behind the first width folding line F1 that passes through the hip flap 4 bends in a direction in which it floats up. However, the identification unit 80 becomes difficult for the user to see. In this aspect, since the identification portion 80 is present in front of the first width folding line F1 passing through the hip flap 4, the user can easily recognize the identification portion 80 while wearing the absorbent article.

  Here, when a plurality of width folding lines pass through the hip flap 4, at least a part of the identifying portion 80 is located on the front side of the rearmost width folding line among the plurality of width folding lines passing through the hip flap. You can stay. Further, it is more preferable that at least a part of the identification portion 80 is located on the front side of the frontmost width folding line among the plurality of width folding lines passing through the hip flap. In this case, it is possible to prevent the identification unit 80 from being hard to be seen by the user due to the area on the rear side of the plurality of width folding lines passing through the hip flap being lifted.

  At least in the region in front of the hip flap release sheet 74, the distance between the pair of hip flaps 4 folded to the skin side is preferably narrowed from the front to the rear (see FIG. 4). Thereby, in a state in which the pair of hip flaps 4 are folded to the skin surface side, the eyes of the user are more likely to go to the center CL of the absorbent article in the width direction W as going from the front side of the hip flaps 4 to the rear side. . Therefore, the user can naturally find the identification part 80, and when wearing the absorbent article 1 on the underwear, try to wear the absorbent article so that the identification part 80 is located at the center of the underwear in the width direction. It becomes easy to do.

  The main body adhesive layer 60 is preferably provided intermittently in the front-rear direction L. In the present embodiment, the non-adhesive region NS is provided between the first main body adhesive layer 61 and the second main body adhesive layer 62.

  If the main body adhesive layer 60 continuously extends in the front-rear direction L, even if the attachment angle or the position in the width direction of the absorbent article is slightly deviated, it is difficult to correct the deviation during the attachment of the absorbent article. . In this aspect, since the main body adhesive layer 60 is intermittently provided in the front-rear direction, the widthwise position of the absorbent article, particularly the rear side area S3, in the region where the main body adhesive layer 60 does not exist (non-adhesive region NS). The position of can be easily adjusted. This makes it possible to easily wear the absorbent article 1 on the underwear from the front side to the rear side while adjusting the position of the absorbent article in the width direction.

  At least a part of the non-adhesive region NS located between the main body adhesive layers 60 in the front-rear direction L is preferably located between the wing center WC in the front-rear direction L and the hip flap center HC in the front-rear direction. . Since the non-adhesive region NS is between the center WC of the wing and the center HC of the hip flap, the user can position the absorbent article in the width direction in the region between the center WC of the wing and the center HC of the hip flap. Can be easily adjusted. This can eliminate the positional deviation in the width direction of the rear region S3 of the absorbent article.

  At least a part of the non-adhesive region NS located between the main body adhesive layers 60 in the front-rear direction is preferably located between the wing release sheet 73 and the hip flap release sheet 74. Here, since the identification portion 80 extends forward from the front end portion of the hip flap release sheet 74, the non-adhesive region NS is located near the identification portion 80. With this, when the user notices that the position of the absorbent article in the width direction is displaced by the identifying unit 80, the user can easily correct the position deviation of the absorbent article in the width direction in the non-adhesive region NS. be able to.

  In the absorbent article packaged by the package, the package is opened, the folded absorbent article is developed, and then the portion for measuring the basis weight is cut out from the absorbent article, and the weight of the cut out portion is measured. . Next, parts other than the absorber such as the skin sheet and the non-skin sheet are removed from the cut-out portion, and the weight of the absorber is measured. The basis weight is calculated based on the weight of the absorber and the area of the portion where the basis weight is measured.

  According to the second embodiment, the color of the colored sheet 33 on the non-skin surface side of the absorbent core 31 is transparent and visible through the low basis weight area 41. When the absorbent article 1 is viewed from the skin surface side, the color of the low basis weight area 41, particularly the first low basis weight area 41a, appears to be different from the color of the surrounding areas. In the second embodiment, the difference in color from the first low weighted area 41a constitutes the identification section 80. In other words, the identification unit 80 is provided on the first low basis weight area 41a lower than the basis weight of the absorbent core 31 around the identification unit and on the non-skin surface side of the absorbent core 31, and the skin surface side of the absorbent core 31. And a colored sheet 33 having a different color from the sheets 10 and 32 provided in. Even in this case, similarly to the first embodiment, the user can prevent the absorbent article, particularly the rear side region S3, from being displaced in the width direction by using the identifying unit 80.

  For the purpose of visually recognizing the colored sheet 33 through the first low basis weight region 41a, the basis weight of the absorbent core 31 in the first low basis weight region 41a is preferably small, and the basis weight of the absorbent core 31 in the first low basis weight region 41a is substantially. Is more preferably zero. Here, "substantially zero" means that the design basis weight is zero, and is a concept that allows a small amount of a part of the absorbent material to be mixed in from the region other than the first low basis weight region 41a in the manufacturing process. Is.

  The position and the like of the identification unit 80 according to the second embodiment are the same as those in the first embodiment, and thus the description thereof will be omitted.
