(1) Outline of embodiment

At least the following matters become clear by description of this specification and an accompanying drawing.

An absorbent article according to one aspect is a post-treatment member having a front-rear direction, a width direction perpendicular to the front-rear direction, a body portion having a top sheet, a back sheet, and an absorbent core, and a hook member protruding to the non-skin surface side An absorbent article comprising: a main body adhesive portion for bonding the main body portion to a wearable article; and the post-treatment member provided on the non-skin surface side of the main body portion in the core arrangement region where the absorbent core is disposed in plan view. and the main body adhesive portion is disposed in a width region extending in the width direction from the post-processing member, and the hook member is joined to the topsheet in a folded state with the skin surface side of the absorbent article inward. made possible. According to this aspect, when the body part is going to be rolled up at the time of disposal, it is common to roll it so that the skin surface side to which the excrement adheres becomes inside. In the folded state with the skin-surface side of the main body inward, the topsheet is disposed so as to cover the non-skin surface of the body, and the hook member positioned on the non-skin-surface side of the body is joined to the topsheet to maintain the rolled-up state of the body. can At this time, the post-treatment member can be bonded to the topsheet in the core arrangement region where the absorbent core is disposed. The absorbent core has high rigidity in the constituent members of the absorbent article, and by maintaining the highly rigid absorbent core in a rounded state, the absorbent article is difficult to develop and easily maintains the rounded state. Moreover, the main body adhesive part which has joined the absorbent article to the wearable article at the time of use is also joined to a topsheet auxiliary|assistantly. Accordingly, the post-treatment member can be bonded to the topsheet, and the body adhesive portion can also be bonded to the topsheet. When the body part is kept in a rounded state at the time of disposal, the absorbent article can be disposed of cleanly by the member for post-treatment.

According to one preferable aspect, in the said width area|region, the said main body adhesive part and the said member for post-processing may be arrange|positioned at intervals in the said width direction. According to this aspect, it becomes difficult to interfere with a main body adhesive part and the member for post-processing, In the state before disposal, the problem that a main body adhesive part and the member for post-processing are unintentionally joined, etc. can be suppressed.

According to one preferred aspect, the distance in the width direction between the main body adhesive portion and the post-treatment member may be longer than the distance in the thickness direction between the non-skin surface side of the main body adhesive portion and the tip of the hook member. The hook member protrudes to the non-skin surface side, and may bend or fall when a force is applied. Since the post-processing member and the main body adhesive part are separated from the main body adhesive part by the length in which the tip of the hook member protrudes toward the non-skin surface side, it is difficult to contact the hook member and the main body adhesive part when the hook member is overturned. Accordingly, it is possible to suppress problems such as unintentionally joining the main body adhesive portion and the post-processing member in the state before disposal.

According to a preferred aspect, the distance in the thickness direction between the non-skin surface of the main body and the tip of the hook member may be longer than the distance in the thickness direction between the non-skin surface of the main body and the non-skin surface of the main body adhesive portion. According to this aspect, since the hook member protrudes toward the non-skin surface side rather than the main body adhesive part, when the body part is rolled up with the skin surface side of the body part inside, the hook member is more easily joined to the topsheet. Accordingly, the rounded state can be maintained by the post-treatment member at the time of disposal, and the absorbent article can be disposed of cleanly.

According to one preferable aspect, the length of the said width direction of the said main body adhesive part may be longer than the length of the said width direction of the said post-processing member. The body adhesive portion has a function of bonding the body portion to the wearable article during use, and also has a function of auxiliary bonding to the topsheet at the time of disposal. Generally, the bending rigidity of the main body adhesive part is lower than the bending rigidity of the member for post-processing, and even if the length of the main body adhesive part is lengthened, it is hard to produce the discomfort at the time of installation. By lengthening the length of the width direction of a main body adhesive part, it becomes easier to ensure the bonding force with respect to the topsheet at the time of disposal, suppressing a feeling of incongruity.

According to one preferable aspect, the area of the said post-processing member should just be less than 20% with respect to the area of the said whole body part. According to this aspect, since the area of the post-treatment member having the hook member is small compared to the overall area of the main body portion, it is possible to suppress the increase in the rigidity of the absorbent article by the post-treatment member, thereby suppressing discomfort during wearing. have.

According to one preferable aspect, the length of the said post-processing member in the said width direction should just be 1/3 or less with respect to the length of the said width direction of the said absorbent core. According to this aspect, the length of the width direction of the member for a post-process is 1/3 with respect to the length of the width direction of a body part, and the width|variety of the member for a post-process is narrow with respect to a main-body part. It is easy to ensure the area which arrange|positions a main body adhesive part, etc. in the width direction of the member for post-processing. Moreover, since the member for post-processing is narrow, the width|variety of the area|region where the topsheet and the hook member contact|connects is narrow, and it is easy to peel the hook member once joined to the topsheet from the topsheet. Therefore, the body portion can be rolled again after being rolled in an unintentional manner. Moreover, since the member for post-processing is narrow, it is easy to open compactly when opening the main body in the width direction using the outer edge of the member for post-processing as a starting point at the time of disposal. Therefore, the absorbent article can be disposed of in a compactly opened state.

According to one preferable aspect, the said post-processing member may be arrange|positioned over the center of the said width direction of the said main-body part. According to this aspect, the center of the width direction of a body part can be joined by the member for post-processing. Generally, the center of the width direction of the body part has the longest length in the front-back direction of the body part. By joining the part with the longest length in the front-back direction of a body part with a hook member, the whole area of the front-back direction of a body part can be maintained in the rounded state. Moreover, in general, when the body part is rolled up at the time of disposal, it is rounded with the center of the width direction of the body part as a starting point. At this time, since the post-processing member is located at the starting point, the post-processing member and the top sheet can be pressed in opposite directions without being conscious during the operation process of rounding the main body, and the hook member It can be bonded to a surface sheet.

According to one preferable aspect, the said post-processing member may be arrange|positioned as a pair with the center of the said width direction of the said main-body part interposed therebetween. According to this aspect, the state rounded over the whole width direction of a main body part can be maintained by a pair of post-processing members which sandwiched the center of the width direction of a main body part. Since the length of the width direction which can be joined by the member for post-processing can be ensured, it is suitable especially in the long main-body part of the length of the width direction.

According to a preferred aspect, the main body portion may have a front region, a central region, and a rear region divided into thirds in the front-rear direction, and the post-processing member may be provided at least in a region overlapping the central region. The central region is located between the beginning of the rolling and the end of the rolling, and is easily covered by the top sheet on the end of the rolling, whether from the front region or from the rear region. According to this aspect, in the region overlapping the central region, the post-treatment member can be joined to the topsheet, the rounded state can be maintained at the time of disposal, and the absorbent article can be disposed of cleanly by the post-treatment member. have.

According to one preferable aspect, the bending starting point part extended in the said width direction may be provided in the outer side of the said front-back direction rather than the said post-processing member in multiple numbers. According to this aspect, when the main body part is rolled up in the front-back direction, it can be rolled up from the bending starting point part as a starting point, and it becomes easy for a user to perform the rolling operation. Moreover, when starting to roll the post-processing member from the area|region of the outer side more in a front-back direction, by rounding the bending starting point part as a starting point, the whole main body part can be rolled up compactly.

According to a preferred aspect, the bending starting point portion may include a folding line for opening the absorbent article so that the skin-surface side faces each other. According to this aspect, it is easy to deform|transform so that the skin-surface side may become close by the crease of a fold line, and it becomes easy to roll up a body part with the skin-surface side inside.

According to a preferred aspect, the bending starting point portion includes an edge crimping portion in which the top sheet and the back sheet are compressed outside the front-rear direction outside the outer edge of the absorbent core in the front-rear direction, and the distance in the front-rear direction between the outer edge of the absorbent core in the front-rear direction and the edge crimp portion may be longer than the thickness of the absorbent core. According to this aspect, the rigidity between the absolutely crimped portion and the outer edge of the absorbent core is far lower than that of the crimped portion and the absorbent core, and it is easy to deform flexibly. In the case where the area between the absolutely crimped portion and the outer edge of the absorbent core is shorter than the thickness of the absorbent core, the area between the absolutely crimped portion and the outer edge of the absorbent core is the area between the absolutely compressed portion and the outer edge of the absorbent core when it begins to roll from the far crimped side. It is difficult to deform flexibly under the influence of thickness, and it becomes difficult to make a starting point of the beginning of rolling. However, since the distance between the absolutely crimped portion and the outer edge of the absorbent core is longer than the thickness of the absorbent core, the area between the far crimped portion and the outer edge of the absorbent core is flexible when starting to roll from the far crimped portion side. It deforms, and it becomes easy to form the starting point of the beginning of rolling. In addition, when the far crimping part side is completely rounded, the region between the far crimping part and the outer edge of the absorbent core is easy to deform flexibly without depending on the rigidity of the absorbent core, and also depending on the thickness difference from the core arrangement region. It becomes easy to deform so as to form a round outer shape, and it becomes easy to roll the body part into a more compact round shape.

According to a preferred aspect, a plurality of fold lines for opening the absorbent article in the front-rear direction are provided in the absorbent article at intervals in the front-rear direction, and the fold lines are in the front-rear direction of the absorbent article. has a first fold line closest to one edge of the absorbent article and a second fold line closest to the other edge edge of the absorbent article in the front-back direction, wherein the post-processing member includes the first fold line and the second fold line. You may arrange|position in the area|region between fold lines. According to this aspect, the region between the first fold line and the second fold line is located between the beginning of the rolling and the end of the rolling, and whether from the front region to the rolled state or from the rear region to the rolled state, or to the end of the rolled end. It is easy to be covered by the surface sheet. Therefore, the rounded state can be maintained by bonding the post-treatment member to the topsheet at the time of disposal, and the absorbent article can be disposed of cleanly by the post-treatment member.

According to one preferable aspect, the said post-processing member may be arrange|positioned, without spanning at least one of the said 1st fold line and the said 2nd fold line. According to this aspect, the crease by the fold line is formed in the main body part. In a state in which the body portion is rolled with the skin side inward, the anterior region and the rear region with the fold line as a boundary are deformed toward the skin face side (inner side) with the fold line as a starting point. When it deforms inward with the fold line as a boundary, the post-processing member and the topsheet are separated, and there is a possibility that the hook member and the topsheet are difficult to join, or the hook member once joined may come off. By not crossing the fold line, it is possible to suppress the unintentional detachment of the joined state of the hook member due to the fold.

According to one preferred aspect, the thickness of the hook member may be thicker than the thickness of the topsheet. According to this aspect, when the hook member is pushed toward the topsheet side, the tip of the hook member passes through the topsheet, and the hook member is easily caught by the topsheet. As a result, the hook member is bonded to the topsheet, the hook member keeps the rounded state, and the post-treatment member makes it easy to discard cleanly.

According to one preferred aspect, the thickness of the hook member may be smaller than the thickness of the topsheet. According to this aspect, when the hook member is pushed toward the topsheet side, the hook member easily enters the topsheet, and the tip of the hook member easily gets caught in the fibers of the topsheet. As a result, the hook member is bonded to the topsheet, the hook member keeps the rounded state, and the post-treatment member makes it easy to discard cleanly.

According to a preferred aspect, the post-processing member has a base sheet bonded to a non-skin surface of the main body portion, and the hook member protrudes from the base sheet toward the non-skin surface, the base sheet and the You may arrange|position in the area|region which overlaps with the bonding area|region to which the main body part was joined in the thickness direction. According to this aspect, the hook member provided in the joining area|region is hard to float with respect to a main-body part, and the position is hard to shift. Accordingly, the hook member is likely to be caught by the topsheet in the process of rolling the main body portion at the time of disposal. Moreover, since the position of the hook member is less likely to be shifted, once the hook member is joined to the topsheet, it is easy to maintain the joined state.

According to a preferred aspect, the color difference ΔE between the non-skin surface of the main body portion and the post-treatment member in plan view from the non-skin surface side of the absorbent article may be 3.0 or more. According to this aspect, since the color difference ΔE between the non-skin surface of the main body and the post-processing member is 3.0 or more, the user easily recognizes the main body and the post-processing member as separate bodies, thereby recognizing the existence of the post-processing member. it gets easier The user can roll up the body part while recognizing the member for post-processing, and it is easy to join the member for post-process to a topsheet.

According to one preferred aspect, the bending rigidity of the post-treatment member may be lower than the bending rigidity of a region in which the topsheet, the backsheet, and the absorbent core are overlapped. When the absorbent article is used, the post-treatment member is disposed on the non-skin surface side of the body portion, and the post-treatment member indirectly contacts the skin. At this time, since the bending rigidity of the member for post-processing is low, the discomfort given to a wearer can be suppressed.

According to a preferred aspect, the absorbent article is opened with the skin surface side of the absorbent article inside before use, and in the opened state of the absorbent article, between the hook member and the top sheet, A structural member constituting the absorbent article may be disposed. According to this aspect, in the opened state, the structural member is arrange|positioned between the topsheet and the hook member, and the topsheet and the hook member do not come into contact with each other. Accordingly, it is possible to suppress the problem that the hook member is unintentionally joined to the topsheet before use.

According to a preferred aspect, the structural member is an individual packaging sheet for individually packaging the absorbent article, and in a state individually packaged by the individual packaging sheet, an adjacent region adjacent to the post-treatment member; The color difference ΔE of the region in which the post-processing member is disposed may be 3.0 or more. According to this aspect, in the state individually packaged by the individual packaging sheet, a user becomes easy to recognize presence of the member for post-processing from the outside of an individual packaging sheet. A user can open an individual packaging sheet while recognizing the member for post-processing, and can use an absorbent article.

According to a preferred aspect, the main body portion has a pair of wings protruding outward in the width direction, and in a state in which the pair of wings are opened toward the skin surface side of the main body portion, at least a portion of the hook member is flat It may overlap the area covered by the said pair of wings in the city. Depending on the user, at the time of disposal, the body part is rolled up in a state with the wing open to the skin surface side. At this time, even if the member for post-processing abuts on the part covered with the topsheet by the wing, the hook member does not join to the topsheet. However, by arranging at least a part of the hook member in the area sandwiched by the pair of wings in plan view, the topsheet is exposed in the area between the open wings, and the post-processing member is surfaced in the area. Can be bonded to the sheet.

According to a preferred aspect, the main body portion has a pair of hip flaps protruding outward in the width direction on the rear side of the wing, and on the non-skin surface of the wing, the wing is attached to the wearing article. A wing adhesive part is provided for the purpose of the hip flap, and a flap adhesive part for bonding the hip flap to the wearing article is installed on the non-skin surface of the hip flap, and the wing and the hip flap are opened to the skin surface side of the body part. , At least a part of the wing adhesive portion may be disposed in a front-rear region extending from the flap adhesive portion in the front-rear direction. Depending on the user, at the time of disposal, the body part may be rolled up with the wings and hip flaps open toward the skin surface side. At this time, even if the member for post-processing abuts on the area|region covered with the topsheet by the wing and the hip flap, the hook member does not join to the topsheet. When the wing adhesive part and the flap adhesive part overlap in the front-back direction, the wing adhesive part and the flap adhesive part join, and the area|region covered with the topsheet by the wing and a hip flap can also be maintained in the rounded state.

According to a preferred aspect, the main body portion has a pair of hip flaps protruding outward in the width direction on the rear side of the wing, and on the non-skin surface of the hip flaps, the hip flaps are attached to the wearing article. The flap adhesive part for joining may be provided, and the said main body adhesive part may be arrange|positioned in front of the said flap adhesive part. According to this aspect, the member for post-processing is arrange|positioned rather than a hip flap. A hip flap is located comparatively in the front side in an absorbent article, and a wing is located in the center in an absorbent article. At least a part of the post-treatment member is disposed on the front side than the front edge of the flap adhesive part and on the back side of the front edge of the wing adhesive part, so that the post-treatment member is It is easy to be covered with the top sheet on the side of the rolled end side. Therefore, the rounded state can be maintained by bonding the post-treatment member to the topsheet at the time of disposal, and the absorbent article can be disposed of cleanly by the post-treatment member.

The main body adhesive part 51 may be arrange|positioned on both sides of the width direction W with respect to the member 30 for post-processing, respectively. In addition, like 2nd Embodiment, the main body adhesive part 51 may extend in the width direction W, and may be arrange|positioned at intervals in the front-back direction L. The adhesive portion 50 may have a function of bonding the body portion 20 to a wearable article during use, and also a function of auxiliary bonding to the topsheet 21 at the time of disposal.

The covering sheet 40 may be arrange|positioned at the non-skin surface side T2 of the member 30 for post-processing, and may cover the hook member 31. As shown in FIG. The covering sheet 40 covers the body part 20 before use, and removes it from the body part 20 at the time of use. The covering sheet 40 may be at least one of the individual packaging sheet 41 which individually wraps the main body part 20, and the release sheet 42 which covers the adhesive part 50. As shown in FIG. By covering the hook member 31 with at least either of the individual packaging sheet 41 and the release sheet 42 , exposure of the hook member 31 to the outside before the use of the absorbent article 1 is suppressed, and the hook member (31) can be protected. Therefore, it is possible to suppress the problem that the hook member 31 is unintentionally damaged before use, or that the hook member 31 unintentionally comes into contact with the skin. The covering sheet 40 of this embodiment is comprised by both the individual packaging sheet 41 and the release sheet 42. As shown in FIG. As shown in FIG. 3 , the release sheet 42 is disposed on the non-skin surface side T2 of the hook member 31 of the post-processing member 30 , and is disposed on the non-skin surface side T2 of the release sheet 42 . Individual packaging sheets 41 may be disposed. Since the release sheet 42 is disposed between the hook member 31 and the individually wrapped sheet 41, the problem that the individually wrapped sheet 41 is unintentionally torn by the hook member 31 can be suppressed. .

The peeling strength of the covering sheet 40 and the member 30 for post-processing is lower than the peeling strength of the non-skin surface of the member 30 for post-processing and the body part 20. As shown in FIG. More specifically, the covering sheet 40 and the hook member 31 are in contact with each other in the individually wrapped state, and the peel strength between the covering sheet 40 and the hook member 31 is determined by the post-processing member 30 and It may be lower than the peel strength of the back sheet 22 . That is, it is sufficient that the covering sheet 40 can be peeled from the hook member 31, without the member 30 for post-processing and the back sheet 22 peeling, when unfolding from an individually packaged state. According to such a structure, at the time of opening from an individually packaged state, the covering sheet from the body part 20 and the member 30 for post-processing without peeling the member 30 for post-processes from the body part 20. (40) can be isolated.

Moreover, the peeling strength of the covering sheet 40 and the adhesive part 50 is higher than the peeling strength of the covering sheet 40 and the member 30 for post-processing. More specifically, in the individually wrapped state, the covering sheet 40 and the main body adhesive part 51 are in contact, and the covering sheet 40 and the hook member 31 are in contact, and the covering sheet 40 and the main body are in contact. The peeling strength of the adhesive portion 51 may be higher than the peeling strength of the covering sheet 40 and the hook member 31 . That is, what is necessary is just to be comprised so that the hook member 31 peels more easily from the covering sheet 40 rather than the main body adhesive part 51 when it develops from an individually wrapped state. In the individually wrapped state, the position shift of the covering sheet 40 can be suppressed by bonding of the covering sheet 40 and the adhesive part 50. As shown in FIG. Moreover, since the hook member 31 is easy to peel from the covering sheet 40, when isolate|separating the covering sheet 40 from the main body 20 and the member 30 for post-processing, the member 30 for post-processing. It is possible to suppress the problem of being caught in the temporary covering sheet 40 .

The peeling strength of the covering sheet 40 and the member 30 for post-processing can be measured as follows. First, in the absorbent article of the opened packaging state, let the absorbent article be the expanded state. The front side of the covering sheet and the front side of the main body were respectively sandwiched by the chuck, and the peel strength in the longitudinal direction was measured with an Instron. In addition, when there are two or more covering sheets, a chuck|zipper picks up the position which overlaps several sheets. After evaluating at a speed|rate of 100 mm/min., let the result which converted the area adhered to N/25 mm be the peeling strength of the covering sheet 40 and the member 30 for post-processing. In addition, it is set as 0N/25mm about the thing which is not adhere|attached and is only in contact.

In addition, the peeling strength of the member 30 for post-processing and the body part 20 can be measured as follows. In the absorbent article in the opened packaging state, let the absorbent article be in the opened state. After removing the body part and the member for post-processing from the covering sheet, the part to which the hook member is affixed is cut off with a cutter. The main body part (at least the back sheet should be fixed) and the post-processing part member were respectively fitted in the chuck, and the peel strength in the longitudinal direction was measured with an Instron. In addition, for a product to which the hook member is adhered to the end, a part that can be fitted into the chuck is produced by cold spraying or the like. However, in order to prevent a decrease in adhesive strength due to cold spray, etc., ensure that at least 1/3 of the total is unaffected. After evaluating at a speed of 100 mm/min., the result obtained by converting the bonded area by N/25 mm is taken as the peeling strength of the post-treatment member 30 and the body portion 20 .

The peeling strength of the covering sheet 40 and the adhesive part 50 can be measured as follows. In the absorbent article in the opened packaging state, let the absorbent article be in the opened state. The front side of the covering sheet and the front side of the main body were respectively sandwiched by the chuck, and the peel strength in the longitudinal direction was measured with an Instron. In addition, when there are two or more covering sheets, a chuck|zipper picks up the position which overlaps several sheets. After performing evaluation at a speed|rate of 100 mm/min., let the result which converted the area adhered to N/25 mm be the peeling strength of the covering sheet 40 and the adhesive part 50.

In the absorbent article 1, the fold line for opening the absorbent article 1 in the front-back direction L may be provided at intervals in the front-back direction. The fold line may extend along the width direction W, and may have the 1st fold line FL1 and the 2nd fold line FL2. The 1st fold line FL1 is closest to one edge of the front-back direction L of the absorbent article 1, and the 2nd fold line FL2 is the front-back direction L of the absorbent article 1 It is closest to the absolute edge of the other. In the example shown in FIGS. 1 and 2, the 1st fold line FL1 is the closest to the trailing edge edge of the absorbent article 1 among some fold lines, and the 2nd fold line FL2 is a some fold line. , closest to the shear edge of the absorbent article (1). Moreover, in a modification, the other folding line extending in the width direction W may be arrange|positioned between the 1st folding line FL1 and the 2nd folding line FL2. The first fold line FL1 and the second fold line FL2 open the absorbent article 1 with the skin surface side T1 of the absorbent article 1 inside at the time of packaging the absorbent article (before use). It is a line to grow. In the absorbent article 1 , the main body 20 and the covering sheet 40 are opened together, and the main body 20 may be individually packaged with the individual packaging sheet 41 . The crease can be specified by the position of the fold, and in the form in which the fold of the main body 20 is difficult to specify, the main body 20 and the post-processing are based on the fold of the covering sheet 40 . You may specify the position of the fold line of the dragon member 30. As shown in FIG.

FIG. 5 is a view showing the absorbent article 1 in a packaged state in which the main body 20 is individually packaged by an individual packaging sheet 41 . Fig. 5(a) is a plan view of an absorbent article in a packaged state, and Fig. 5(b) is a cross-sectional view taken along the line C-C shown in Fig. 5(a). The main body 20 and the covering sheet 40 are opened together with the main body 20 disposed on the individual packaging sheet 41 and the release sheet 42 . As an example of the unfolding mode, in a state in which the body portion 20 is disposed on the individual packaging sheet 41 and the release sheet 42 , the trailing edge of the absorbent article 1 is taken from the first fold line FL1 as a starting point. The side may open inward in the front-back direction L, and then, the front-end edge side of the absorbent article 1 may open inward in the front-back direction with the 2nd fold line FL2 as a starting point. At this time, you may open so that skin-surface side T1 comrades of the main-body part 20 may oppose. The tip of the area opened with the second fold line FL2 as a starting point (specifically, the leading edge of the individually wrapped sheet 41) is on top of the individually wrapped sheet 41 opened with the first fold line FL1 as a starting point. It is fixed by a tape member 45 . By being opened in this way, the main body 20 is individually packaged with the individual packaging sheet 41 . In addition, in the modification, it is not necessary to have the tape member 45 .

In the state in which the absorbent article 1 is opened, it is preferable that the topsheet 21 and the post-treatment member 30 do not contact each other. In the absorbent article 1 of this embodiment, in the state opened before use, the topsheet 21 is not arrange|positioned so that the non-skin surface side T2 of the member 30 for post-processing may be covered, and the topsheet 21 is not opened before use. In this state, the post-processing member 30 and the topsheet 21 do not come into contact, and the hook member 31 does not unintentionally adhere to the topsheet 21 . However, in the form in which the fold line extending in the width direction (W) is three or more lines and the form in which the post-processing member 30 is arranged across the fold line in the front-rear direction (L), in an open state such as a packaging state WHEREIN: The topsheet 21 may be arrange|positioned so that the non-skin surface side T2 of the member 30 for post-processing may be covered. In such a form, it is preferable that the structural member which comprises the absorbent article 1 is arrange|positioned between the hook member 31 and the topsheet 21. As shown in FIG. This structural member may be, for example, the covering sheet 40 . In the opened state, the structural member is disposed between the topsheet 21 and the hook member 31 , so that the topsheet 21 and the hook member 31 do not come into contact with each other. Accordingly, it is possible to suppress the problem that the hook member 31 is unintentionally joined to the topsheet 21 before use.

Next, based on FIG. 6, an example of the disposal aspect of the absorbent article 1 is demonstrated. Because excrement adheres to the topsheet 21 after use, the user may discard the absorbent article 1 by rolling the skin-surface side T1 of the main body 20 inward. At this time, as shown to Fig.6 (a), the body part 20 and the member 30 for post-processing are rounded in the front-back direction L from the front-end edge or the rear-end edge of the body part 20. As shown in FIG. While the non-skin surface side T2 of the rolling start portion of the main body 20 is in contact with the top sheet 21, the main body 20 is rolled in the front-rear direction L. On the non-skin-surface side T2 of the main body 20, a hook member 31 protruding toward the non-skin-surface side T2 is provided. When the main body 20 and the post-processing member 30 are further rolled in the front-back direction L from the state shown in FIG. 6( a ), the hook member 31 abuts against the topsheet 21 . The umbrella portion 312 of the hook member 31 is caught by the fibers of the topsheet 21 , and the hook member 31 is joined to the topsheet 21 . With the post-treatment member 30, the absorbent article 1 can be disposed of in a clean state with the surface to which excrement adhered inside. Since the hook member 31 is caught between the fibers of the topsheet 21 to achieve a bonding state, the topsheet 21 is wetted by the adhesion of body fluids such as menstrual blood, and the adhesive portion 50 and the topsheet 21 are ), even when it is difficult to obtain the bonding force, the post-treatment member and the surface sheet can be bonded. In particular, since the adhesive part is in a situation in which the bonding strength is lowered and the topsheet is damp after bonding to the undergarment or the like, it is difficult to bond the topsheet and the adhesive part 50 to each other, so the post-treatment member 30 can be joined by In addition, the operation of joining the hook member 31 of the member 30 for post-processing to the topsheet 21 can be performed in the process of rolling the main body 20 into a circle, and holding the member 30 for post-processing There is no need for a separate operation such as pulling and joining. Therefore, even when the user discards it without being particularly conscious of it, the state in which the body part 20 is rolled up can also be maintained by the member 30 for post-processing.

In the state in which the absorbent article 1 is rolled up, the main body adhesive portion 51 also abuts against the topsheet 21 . The main body adhesive part 51 has a function of joining the main body part 20 to a wearable article at the time of use, and even after removing the main body part 20 from a wearing article, it has adhesive force even a little. The main body adhesive part 51 is also attached to the topsheet 21 auxiliaryly. Accordingly, the post-processing member 30 can be bonded to the topsheet 21 , and the body adhesive portion 51 can also be bonded to the topsheet 21 . The post-processing member 30 and the main body adhesive part 51 may be arrange|positioned in the core arrangement area|region R23. The absorbent core 23 has high rigidity in the constituent members of the absorbent article 1 . By keeping the absorbent core 23 with high rigidity in the rounded state, the main body 20 is difficult to deploy and easily maintains the rounded state.

At least a part of the main body adhesive part 51 may be arrange|positioned in the width area|region RW extended in the width direction W from the member 30 for post-processing. Width region RW is an area|region extended in the width direction from the whole area of the front-back direction L of the member 30 for post-processes, In the form in which the some member 30 for post-processes is arrange|positioned, multiple installed. In Fig. 2, the width region RW is indicated by slanting. By disposing the main body adhesive part 51 in the width region RW, both the main body adhesive part 51 and the post-processing member 30 are arrange|positioned on arbitrary imaginary lines extending in the width direction W. . On the said imaginary line, both the main body adhesive part 51 and the member 30 for post-processing are joined to the topsheet 21, and it becomes easier to maintain the rolled state. More suitably, the main body adhesive part 51 and the hook member 31 may be arrange|positioned on arbitrary imaginary lines along the width direction W.

As shown in FIG. 4, in the width region RW, the main body adhesion part 51 and the member 30 for post-processing may be spaced apart in the width direction W, and may be arrange|positioned. Since the main body adhesive part 51 and the post-treatment member 30 are less likely to interfere, problems such as unintentional bonding of the main body adhesive part 51 and the post-processing member 30 before disposal can be suppressed. have. In addition, in a modification, the main body adhesive part 51 and the member 30 for post-processing may adjoin in the width direction W. As shown in FIG. In this modified example, it is preferable that the main body adhesive part 51 and the hook member 31 are spaced apart in the width direction W, and are arrange|positioned.

As shown in FIG. 4, the distance D11 in the width direction W of the main body adhesive part 51 and the member 30 for post-processing is the surface of the non-skin surface side T2 of the main body adhesive part 51 and It may be longer than the distance D12 in the thickness direction T with the tip 31P of the hook member 31 . The tip 31P of the hook member 31 is the most protruding edge of the hook member 31 , and in the present embodiment is the edge of the non-skin surface side T2 of the umbrella part 312 . The surface on the non-skin surface side T2 of the main body adhesive portion 51 is the surface that the post-processing member 30 comes into contact with in the main body portion 20 , and in this embodiment, the non-skin surface of the back sheet 22 . is the side In addition, the distance D12 is (thickness T30 of the post-processing member with respect to the non-skin side surface of the main body part 20 (the non-skin side surface of the back sheet 22)) - (the body part 20) You may calculate by the thickness (T51) of the main body adhesive part 51 with respect to the non-skin side surface (non-skin side surface of the back sheet 22) of The hook member 31 protrudes to the non-skin surface side T2, and may bend or fall when a force is applied. The post-processing member 30 and the main body adhesive part 51 are longer than the length D12 in which the tip 31P of the hook member 31 protrudes toward the non-skin surface side T2 with respect to the body adhesive part 51. Since they are apart, when the hook member 31 falls, the hook member 31 and the main body adhesive part 51 are hard to contact. Accordingly, it is possible to suppress problems such as unintentionally joining the main body adhesive portion 51 and the post-treatment member 30 to each other in the state before disposal. In addition, in the modification, it is not necessary to have the main body adhesive part 51 .

The distance T30 in the thickness direction T between the non-skin surface of the body part 20 and the tip of the hook member 31 is the non-skin surface of the body part 20 and the non-skin surface of the body adhesive part 51 . It may be longer than the distance T51 in the thickness direction T with respect to a surface. The distance T30 in the thickness direction T between the non-skin surface of the main body 20 and the tip of the hook member 31 is the thickness of the post-processing member 30, specifically, 0.05 mm or more and 1.0 mm or less. If it is less than 0.05 mm, it is difficult to sufficiently obtain the force which the post-processing member 30 joins to the topsheet 21. Moreover, when it is longer than 1.0 mm and the member 30 for post-processes contacts skin, the discomfort to skin may become high. In addition, the distance T51 in the thickness direction T between the non-skin surface of the main body 20 and the non-skin surface of the main body adhesive part 51 is the length in the thickness direction T of the body adhesive part 51 . and specifically, 0.1 mm or less may be sufficient. The hook member 31 protrudes to the non-skin surface side T2 rather than the main body adhesive portion 51, and the body portion 20 and the post-processing member ( When the 30) is rolled up, the hook member 31 is more easily joined to the topsheet 21. Therefore, the rounded state can be maintained by the post-processing member 30 at the time of disposal, and the main body 20 can be disposed of cleanly.

The length of the width direction W of the main body adhesive part 51 may be longer than the length of the width direction W of the member 30 for post-processing. As in this embodiment, in the form in which the main body adhesive parts 51 are spaced apart in the width direction W and are arrange|positioned in multiple rows, the length of the width direction W of the main body adhesive parts 51 is each body adhesive It is the total length of the width direction W of the part 51. The body adhesive portion 51 has a function of bonding the body portion 20 to the wearable article during use, and also has a function of auxiliary bonding to the topsheet 21 during disposal. Generally, the bending rigidity of the main body adhesive part 51 is lower than the bending rigidity of the member 30 for post-processing, and even if the length of the main body adhesive part 51 is lengthened, it is difficult to produce the discomfort at the time of attachment. By lengthening the length of the width direction W of the main body adhesive part 51, it becomes easier to ensure the bonding force with respect to the topsheet 21 at the time of disposal, suppressing a sense of incongruity. Similarly, the length of the front-back direction L of the main body adhesive part 51 may be longer than the length of the front-back direction L of the member 30 for post-processing. As in the second embodiment, in the form in which the main body adhesive parts 51 are arranged in a plurality of rows at intervals in the front-back direction L, the length of the main body adhesive parts 51 in the front-back direction L is equal to each body. It is the total length of the front-back direction L of the adhesive part 51. By lengthening the length of the front-back direction L of the main body adhesive part 51, it becomes easier to ensure the bonding force with respect to the topsheet 21 at the time of disposal, suppressing a sense of incongruity.

The post-processing member 30 should just be provided with the dimension required in order to ensure the adhesive force with respect to the topsheet 21, suppressing the discomfort at the time of attachment. The length of the front-back direction L of the member 30 for post-processing may be longer than the thickness of the absorbent core 23, and may be shorter than the length of the front-back direction of an absorbent core, The length of the member 30 for post-processes of this embodiment The length in the front-back direction L is 80 mm. The length of the front-back direction L of the member 30 for post-processing is longer than the thickness of an absorbent core, and when the body part 20 is wound up, the member 30 for post-processing and the top sheet 21 are points. It is possible to suppress the contact with the surface and ensure a contact area between the post-processing member 30 and the top sheet 21 . In addition, since the length in the front-back direction L of the post-treatment member 30 is shorter than the length in the front-back direction of the absorbent core, the rigidity of the post-treatment member 30 is suppressed from being transmitted to the skin surface of the body portion, It can reduce discomfort. The length of the width direction W of the member 30 for post-processing may be 1 mm or more and the length of the width direction of an absorbent core or less may be sufficient as it. When the length of the width direction W of the member 30 for post-processing is 1 mm or more, it is easy to ensure the bonding strength with respect to a topsheet. In addition, since the length in the width direction W of the post-treatment member 30 is less than the length in the width direction of the absorbent core, the body adhesive portion can be disposed in the width region, and the body portion can be stably bonded to the wearing article. have. More preferably, the length of the width direction of the member 30 for a post-process is 5 mm or more and 35 mm or less, The length of the width direction W of the member 30 for a post-process of this embodiment is 15 mm. The post-processing member can be produced stably, and the main body adhesive portion is also easily disposed within the core arrangement region, so that the main body portion can be stably joined to the wearing article. The area of the member 30 for post-processing should just be less than 20% with respect to the area of the whole body part 20. As shown in FIG. Since the area of the member 30 for post-treatment having the hook member 31 is smaller than the area of the entire body portion 20, it is suppressed that the rigidity of the absorbent article 1 is increased by the member 30 for post-treatment. Thus, it is possible to suppress a sense of discomfort during wearing.

The length of the post-processing member 30 in the width direction W may be 1/3 or less with respect to the length of the absorbent core 23 in the width direction. In the form in which the length in the width direction W of the absorbent core 23 changes, the length in the width direction W of the post-treatment member 30 is 1 with respect to the maximum length in the width direction of the absorbent core 23 . /3 is fine. The post-processing member 30 has a narrow width with respect to the main body portion 20, and it is easy to secure an area for arranging the main body adhesive part 51 on the outer side of the post-processing member 30 in the width direction W or the like. . Moreover, since the member 30 for post-processing is narrow, the width of the region where the topsheet 21 and the hook member 31 are in contact is narrow, and the hook member 31 once joined is peeled from the topsheet 21 . easy to do Therefore, the body portion 20 can be rolled again after being rolled in an unintended manner. Moreover, since the member 30 for post-processing is narrow, it is easy to open compactly when opening the main body 20 in the width direction with the outer edge of the member 30 for post-processing as a starting point at the time of disposal. Accordingly, the main body 20 can be disposed of in a compactly opened state.

The member 30 for post-processing may be arrange|positioned over the center 20CW of the width direction W of the main-body part 20. The center 20CW of the width direction W of the main body 20 can be joined by the post-processing member 30 . In general, the center of the width direction W of the main body 20 has the longest length in the front-rear direction L of the main body 20 . By joining the longest portion in the front-rear direction L of the main body 20 with the hook member 31 , the entire area in the front-rear direction L of the main body 20 can be maintained in a rounded state. Moreover, in general, when the main body part 20 is rolled up at the time of disposal, it is made round with the center 20CW of the width direction of the main body part 20 as a starting point. At this time, since the post-treatment member 30 is located at the starting point, the direction in which the post-treatment member 30 and the topsheet 21 face each other without being conscious of the operation process of rolling the main body 20 into a circle. can be pushed and pressed, and the hook member 31 can be joined to the top sheet 21 . A modification WHEREIN: The member 30 for post-processing may be arrange|positioned in a pair with the center of the width direction W of the main-body part 20 interposed therebetween. A state of being rounded over the entire width direction W of the main body 20 by a pair of post-processing members 30 with the center 20CW in the width direction W of the main body 20 interposed therebetween. can keep Since the length of the width direction W which can be joined by the member 30 for a post-process can be ensured, it is suitable especially in the absorbent article with a long length of the width direction W.

The member 30 for post-processing may be provided in the area|region which overlaps with center area|region S2 at least. The center region S2 is located between the beginning of the rolling and the end of the rolling, and the top sheet 21 on the end side of the rolling, whether from the front region S1 or from the rear region S3 or from the rounded state. easy to be covered by By bonding the post-processing member 30 and the topsheet 21 in the region overlapping the central region S2, the rounded state of the body portion 20 can be maintained at the time of disposal, and the post-processing member 30 ), the absorbent article 1 can be disposed of cleanly. Moreover, the member 30 for post-processing may be arrange|positioned over the center of the front-back direction of the main-body part 20. As shown in FIG.

A plurality of bending starting point portions 80 extending in the width direction may be provided outside the member 30 for post-processing in the front-back direction L. The bending starting point part 80 becomes a starting point when bending the main body part 20 in the front-back direction L. The bending starting point portion 80 makes it easy to bend the body portion 20 due to a difference in stiffness, a difference in thickness, a difference in basis weight, and the like. When the body portion 20 is rolled in the front-back direction L, it can be rolled with the bending starting point portion 80 as a starting point, so that the user can easily perform the rolling operation. At this time, since the deformation origin at the time of rolling the main body part 20 is extended along the width direction, it becomes easy to roll the whole width direction W of the main body part 20 in the front-back direction L. Moreover, when starting to roll the member 30 for post-processing more from the area outside the front-back direction L, by making the bending starting point part 80 as a starting point, the whole main body part 20 is rolled up compactly. can

What is necessary is just to provide the some bending starting point part 80 in at least either of the area|region of the front side of the member 30 for post-processing, and the area|region of a rear side. Preferably, the some bending starting point part 80 may be provided in both the area|region of the front side of the member 30 for post-processing, and the area|region of a rear side, respectively. It becomes easy to roll the body part 20 whole in the front-back direction L. Moreover, in the structure in which the bending starting point part 80 is spaced apart in the front-back direction L, and is provided in multiple numbers, each functions as the bending starting point part 80. As shown in FIG. However, when the distance in the front-back direction L between the bending starting point portions 80 is 5 mm or less, since it functions as an integrated deformation starting point, all of the plurality of bending starting point parts provided at intervals of 5 mm or less are one bending starting point part. make up

The bending starting point portion 80 may include a crimping portion in which at least one of the topsheet 21 and the absorbent core 23 is pressed. More specifically, the front and rear edges of the crimping portion constitute the bending starting point portion 80 . Moreover, in the structure in which the some crimping|compression-bonding part is shifted in the front-back direction L, and is arrange|positioned, the front-end edge and the rear-end edge of each crimp part comprise the bending starting point part 80. As shown in FIG. The crimping portion constituting the bending starting point portion 80 may be at least a compressed portion of the absorbent core 23 , or may be at least a compressed portion of the topsheet 21 . In the main body portion 20 of the present embodiment, the top sheet 21 and the back sheet 22 are compressed outside the front-rear direction L rather than the outer edge of the absorbent core 23 in the front-rear direction L. By far the crimping portion 27 is provided. By far the crimping portion 27 constitutes the bending starting point portion 80 . The crimping portion has a higher rigidity and a smaller thickness than a region in which the crimping portion is not formed. When the crimping portion constitutes the bending starting point portion 80 , the main body portion 20 is easily rolled into a compact shape according to the thickness difference and the difference in stiffness. Suitably, the crimping portion may be dented from the skin-surface side T1 to the non-skin-surface side T2. The user generally rounds the body portion 20 with the skin surface side T1 to which the excrement is attached at the time of disposal as the inside. Since the crimping portion is recessed from the skin surface side T1 to the non-skin surface side T2, it is easy to deform so that the skin surface side T1 approaches, and the body portion 20 is rolled with the skin surface side T1 inside. it gets easier

The bending starting point portion 80 may include a basis weight change portion. The basis weight change part is a part in which the basis weight of the absorbent material of the absorbent core 23 differs with respect to the area|region adjacent in the front-back direction L. Specifically, the front and rear edges of the absorbent core 23 constitute the basis weight change portion. The leading edge and trailing edge of the high basis weight part, and the basis weight change part are constituted. The low basis weight part differs with the length in the front-back direction. When the length in the front-back direction of the low basis weight part is less than 20 mm, the center of the front-back direction of the said low basis weight part constitutes a basis weight change part. When the length in the front-rear direction of the low basis weight part is 20 mm or more, the front and rear edges of the low basis weight part constitute the basis weight change part. Moreover, when a plurality of low basis weight portions are provided apart from each other in the front-rear direction, and the plurality of low basis weight portions are arranged side by side, each of the low basis weight portions separated in the front-rear direction constitutes a basis weight change portion. The basis weight change portion configured as described above has a different basis weight of the absorbent material from a region adjacent to each other in the front-rear direction, and the thickness and rigidity of the absorbent core 23 are different. When the basis weight change portion constitutes the bending starting point portion, the absorbent article can be easily rolled into a compact shape due to the difference in thickness and stiffness.

The bending starting point portion 80 may include a low basis weight portion provided in the absorbent core 23 as a basis weight change portion. The low basis weight part has high rigidity and a thin thickness compared with the area|region in which the low basis weight part is not formed. When the low basis weight part constitutes the bending starting point part 80, it becomes easy to roll the main body part 20 round by the thickness difference and rigidity difference. Preferably, the low basis weight part as a basis weight change part may be provided along the width direction W. In the cross-sectional view along the front-back direction L, as for the length in the front-back direction of a low basis weight part, the skin-surface side may be longer than the non-skin side. Since the length in the front-back direction on the skin surface side of the low basis weight portion is longer than the length in the front-back direction on the non-skin surface side of the low basis weight portion, it is easy to deform so that the skin surface side T1 approaches, and the skin surface side T1 is turned inside. This makes it easier to roll the main body 20 into a round shape.

The bending starting point portion 80 may include a first folding line FL1 and a second folding line FL2 that are opened so that the skin surface side T1 of the absorbent article 1 faces each other. In the configuration in which the fold line has a constant length in the front-back direction L, the front and rear edges of the first fold line FL1 and the front and rear edges of the second fold line FL2 are the bending origins. constitutes part 80 . The folds of the first fold line FL1 and the second fold line FL2 make it easy to deform so that the skin surface side approaches, and it is easy to roll the body part 20 with the skin surface side inside. That is, the bending starting point part 80 may be comprised by at least any one of a crimping|compression-bonding part, a basis weight change part, and a fold line. Thus, by providing the bending starting point part 80, a user becomes easy to wind the absorbent article 1 in a front-back direction, and it becomes easy to discard it in a rolled state.

The shape of the bending starting point part 80 is not limited, Point shape may be sufficient, band shape may be sufficient, arc shape may be sufficient, and polygonal shape may be sufficient as it. The bending starting point part 80 may have a 1st bending starting point part and a 2nd bending starting point part. The length in the width direction of the first bending starting point portion is longer than the length in the front-back direction of the first bending starting point portion. The length of the front-back direction of the 2nd bending starting point part is longer than the length of the width direction W of the 2nd bending starting point part. The body part 20 becomes easy to bend in the front-back direction L with a 1st bending starting point part as a starting point, and also becomes easy to bend also in the width direction W with a 2nd bending starting point part as a starting point. The number of 1st bending starting point parts in the whole absorbent article may be larger than the number of 2nd bending starting point parts. When the body part 20 is rolled up, it becomes easy to roll in the front-back direction rather than the width direction. Therefore, it becomes easy to roll an absorbent article compactly by the front-back direction, and it becomes easy to maintain the state which was rolled more easily.

Three or more bending starting point parts 80 may be provided in the range from the outer edge of the front-back direction of the main-body part 20 to 1/3 of the length of the front-back direction of the main-body part 20. As shown in FIG. The circumferential length of the body part 20 in a state in which it is rounded in the front-back direction L is generally about 1/3 of the length of the body part 20 in the front-back direction L. 1/3 of the length of the front-rear direction L of the main body 20 is the area at the beginning of the end or the area at the end of the end. When three or more bending starting point portions 80 are provided in the portion, it becomes easier to maintain the rounded state.

Even if the distance D27 (refer to FIG. 1) in the front-rear direction between the outer edge of the absorbent core 23 in the front-rear direction and the far crimping portion 27 is longer than the length 23T in the thickness direction of the absorbent core (refer to FIG. 3), do. The rigidity between the far crimped portion 27 and the outer edge of the absorbent core 23 is far lower than that of the far crimped portion 27 and the absorbent core 23, and thus it is easy to deform flexibly. If the area between the far crimped portion 27 and the outer edge of the absorbent core 23 is shorter than the length T23 in the thickness direction of the absorbent core 23, the body portion 20 is removed from the far crimped portion 27 side. When rolling begins, the region between the far-compressed portion 27 and the outer edge of the absorbent core 23 is difficult to deform flexibly under the influence of the thickness of the absorbent core 23, creating a starting point for starting rolling it gets difficult However, since the distance between the far crimped portion 27 and the outer edge of the absorbent core 23 is longer than the thickness of the absorbent core 23, when it begins to roll from the far crimped portion 27 side, the far crimped portion The region between (27) and the outer edge of the absorbent core 23 is flexibly deformed, and it is easy to form a starting point for starting to roll. In addition, when the far crimped portion 27 side is finished rolling, the area between the far crimped portion 27 and the outer edge of the absorbent core 23 is not subject to rigidity of the absorbent core 23 and is not deformed flexibly. It is easy, and it is easy to deform so as to form a round outer shape according to the thickness difference with the core arrangement area, and it becomes easy to roll the body part 20 into a more compact round shape.

The member 30 for post-processing may be arrange|positioned in the area|region between the 1st fold line FL1 and the 2nd fold line FL2. At least a part of the member 30 for post-processing should just be arrange|positioned between the 1st fold line FL1 and the 2nd fold line FL2, The 1st fold line FL1 and the 2nd fold line FL2 The member 30 for post-processing may be arrange|positioned over it. The area between the first fold line FL1 and the second fold line FL2 is located between the beginning of the rolling and the end of the rolling, and even in the state of being rolled from the front area S1, the rear area S3 Even if it is in a state of being rolled from the top, it is easy to be covered by the top sheet 21 on the side of the rolled end. Accordingly, when the post-treatment member 30 is bonded to the topsheet 21 at the time of disposal, the rounded state can be maintained, and the absorbent article can be disposed of cleanly by the post-treatment member 30 .

The member 30 for post-processing may be arrange|positioned, without spanning at least one of 1st folding line FL1 and 2nd folding line FL2. The body portion 20 is formed with folds by fold lines. In the state in which the skin surface side T1 is turned inside, the anterior region and the rear region with the fold line as a boundary are deformed toward the skin surface side (inner side) with the fold line as a starting point. If it is deformed inward with the fold line as a boundary, the post-processing member 30 and the topsheet 21 are separated, making it difficult to bond the hook member 31 and the topsheet 21, or the hook member once joined ( 31) may fall out. By not crossing the fold line, it is possible to suppress the unintentional detachment of the joined state of the hook member 31 due to the fold. Moreover, when the body part 20 is rolled up, by weaving it from the fold line side where the post-processing member 30 does not span, without receiving the repulsive force which is going to return to the planar state by the post-processing member 30, it is rounded. It can be rolled up, and it is more compact and is easy to roll with a weak force. Moreover, since the member 30 for post-processing is arrange|positioned across the fold line covered by the topsheet 21 when it is rolled up, the hook member 31 is caused by the repulsive force by the member 30 for post-processing. and the topsheet 21 are easily bonded.

As shown in FIG. 4 , the thickness T31 of the hook member 31 may be thicker than the thickness T21 of the topsheet 21 . The thickness T31 of the hook member 31 is the sum of the thickness of the shaft portion 311 and the thickness of the umbrella portion 312 . When the hook member 31 is pushed toward the topsheet 21 , the tip of the hook member 31 penetrates the topsheet 21 , and the umbrella portion 312 of the hook member 31 is attached to the topsheet 21 . ) is more prone to As a result, the hook member 31 is joined to the topsheet 21, the hook member 31 maintains a rounded state, and the post-processing member 30 makes it easy to discard cleanly.

In addition, in the modification, the thickness T31 of the hook member 31 may be smaller than the thickness T21 of the topsheet 21 . When the hook member 31 is pushed toward the topsheet 21 side, the umbrella portion 312 of the hook member 31 stays inside the topsheet 21, and the umbrella portion 312 of the hook member 31 is It is easy to get caught in the fibers of the topsheet 21. As a result, the hook member 31 is joined to the topsheet 21, the hook member 31 maintains a rounded state, and the post-processing member 30 makes it easy to discard cleanly.

The hook member 31 protrudes from the base sheet 35 to the non-skin surface side T2, and is in a region overlapping the bonding region where the base sheet 35 and the body portion 20 are joined in the thickness direction T. may be placed. The bonding area|region of this embodiment is provided in the whole area|region in which the base material sheet 35 is arrange|positioned. The hook member 31 provided in the bonding area is less likely to float with respect to the back sheet 22, and the position thereof is less likely to be shifted. Accordingly, the hook member 31 is likely to be caught by the topsheet 21 in the process of rolling the body portion 20 into a circle at the time of disposal. Moreover, since the position of the hook member 31 is not easily shifted, once the hook member 31 is joined to the topsheet 21, the bonding state is easily maintained.

In a plan view from the non-skin surface side T2 of the absorbent article 1, the color difference ΔE between the non-skin surface of the body portion 20 and the post-treatment member 30 may be 3.0 or more. Since the color difference ΔE between the non-skin surface of the main body 20 and the post-processing member is 3.0 or more, the user easily recognizes the main body 20 and the post-processing member 30 as separate bodies, and the post-processing member It becomes easy to recognize the existence of (30). Further, in a form in which the non-skin surface of the main body portion 20 has a plurality of colors, such as a form in which a print is applied to the back sheet 22, the color of the region occupying the largest area and the member 30 for post-processing It is preferable that the color difference ΔE of is not less than 3.0. As a result of repeated examinations by the applicant, it was found that, in general, when the color difference ΔE is 3.0 or more, the user can easily recognize two regions as different regions. When the color difference ΔE between the non-skin surface of the main body 20 and the post-processing member 30 is 3.0 or more, the user can easily recognize the main body 20 and the post-processing member 30 as separate bodies, It becomes easy to recognize presence of the member 30 for a process. The user can roll the body portion 20 while recognizing the post-processing member 30 , so that the post-processing member 30 is easily bonded to the topsheet 21 .

In addition, if the color difference ΔE between the region adjacent to the post-processing member 30 and the region where the post-processing member 30 is disposed in the state individually wrapped with the individual packaging sheet 41 is 3.0 or more, good. In the state packaged by the individual packaging sheet, a user becomes easy to recognize presence of the member 30 for post-processing. The user can use the absorbent article by opening the individual packaging sheet 41 while recognizing the post-processing member 30 . In addition, in the configuration in which the individual packaging sheet 41 and the release sheet 42 are disposed on the non-skin side side of the main body 20 , the individual packaging sheet 41 and the release sheet 42 are interposed therebetween for post-processing What is necessary is just to be comprised so that the visibility of a member may be conspicuous with respect to an adjacent area|region.

The color difference ΔE between the main body 20 and the post-processing member 30 and the color difference ΔE between the adjacent region and the post-processing member 30 are measured at two points (two regions) using a commercially available colorimeter. This can be obtained by performing colorimetry and comparing values digitized based on the CIE1976 (L*a*b*) color space specified in JIS Z 8729. Specifically, when the difference in the L* value between the two points to be measured is ΔL*, the difference in the a* value is Δa*, and the difference in the b* value is Δb*, the color difference ΔE=[(ΔL*) ² +(Δa*) ² + (Δb*) ² ] 1/2.

The bending rigidity of the post-processing member 30 may be lower than the bending rigidity of a region where the topsheet 21 , the backsheet 22 and the absorbent core 23 are overlapped. When the absorbent article 1 is used, the post-treatment member 30 is disposed on the non-skin surface side T2 of the body portion 20, and the post-treatment member 30 indirectly contacts the skin. At this time, since the bending rigidity of the member 30 for post-processing is low, the discomfort given to a wearer can be suppressed.

In addition, the bending rigidity of the post-treatment member 30, the bending rigidity of the portion where the backsheet 22, the absorbent core 23, and the topsheet 21, the backsheet 22, and the absorbent core 23 are overlapped are, It is measured by the Taber method prescribed by the standard JIS P-8125. For example, first, a test piece with a width of 25 mm and a length of 38 mm is taken from a member (sheet) to be measured. Next, the thickness of the test piece is measured with a thickness gauge (for example, 44 mmφ 3 g/m ^{2 manufactured by PEACOCK).} Next, the test piece is installed in the Taber Stiffness Tester manufactured by Seigi Yasuda. Next, the test piece is put between the rollers of the Taber stiffness tester, and the grip gap is fitted according to the thickness of the test piece. Also, match the upper end of the test piece with the upper surface of the grip. Adjust the distance between the roller and the test piece to about 0.5 mm so as not to press the test piece. Rotate the specimen bending device of the Taber Stiffness Tester, stop the rotation of the bending device at the point where the angle line indicating 15 degrees of the specimen bending device coincides with the guideline of the load pendulum. Read the load scale. Immediately rotate the load pendulum in the reverse direction, read the load scale in the same way, and find the average value of the load scale in both left and right directions. In addition, the auxiliary weight is arbitrarily selected so that the indicated load scale falls within the range of 15 to 85% of the maximum scale. And the bending stiffness (strength (g. cm)) of the test piece is computed by the formula of "strength (g. cm) = average value of load scale x 10 x value of weight". In addition, when the length of the width direction of a sample is less than 25 mm, the data measured by the maximum width of a sample is converted into N/25mm. In addition, bending rigidity is measured three times, and let it be the average value.
