The main body adhesive part is provided on the surface facing the back sheet side in the extended state, is bonded to the back sheet when discarded, and is fixed in a state where the absorbent article is agglomerated. Hitherto, there has been a demand for absorbent articles that can be tightly lumped and maintain a lumped state when discarded, such as the absorbent article of Patent Document 1. However, absorbent articles with a belt member for disposal have not been sufficiently popularized. Depending on the user, the operation of extending the belt member may not be performed smoothly, or the main body adhesive part of the belt member cannot be joined to the desired There is room for improvement in operability. Therefore, an absorbent article that can be cleanly discarded in a state of being agglomerated by a post-processing member is desired. [Means used to solve the problem]

One aspect of the absorbent article has: a front-to-rear direction; a width direction, which is orthogonal to the aforementioned front-to-rear direction; a main body, which has a surface sheet, a back sheet, and an absorbent core; and a post-treatment member, which has a non-skin facing The hook member protruding on the surface side is characterized in that the non-skin surface side of the main body part where the core material arrangement area of the absorbent core material is arranged in a plan view is provided with a main body adhesive part for joining the main body part to the wearing article and In the post-treatment member, the body bonding portion is arranged in a width area extending from the post-treatment member in the width direction, and the hook member is configured to be bent so that the skin surface side of the absorbent article is inside The hook member can be joined to the surface sheet in the state of the absorbent article.

(1) Outline of the embodiment Based on the description in this manual and the drawings, at least the following items can be determined. An absorbent article according to one aspect of the present invention has: a front-to-rear direction; a width direction which is orthogonal to the aforementioned front-to-rear direction; a body portion having a surface sheet, a back sheet and an absorbent core; and a post-processing member, which It has a hook member protruding to the non-skin surface side, and is characterized in that the non-skin surface side of the main body part where the core material arrangement area of the absorbent core material is disposed in a plan view is provided with a means for joining the main body part to the wearing article The body bonding part and the post-treatment member, the body bonding part is arranged in a width area extending from the post-treatment member in the width direction, and the hook member is configured to be located inside from the skin surface side of the absorbent article The hook member can be joined to the surface sheet in a state in which the absorbent article is folded. According to this aspect, if it is desired to massify the main body at the time of disposal, it is usually massed so that the side of the skin surface to which the excrement is attached becomes the inside. With the skin surface side of the main body portion being bent on the inside, the surface sheet is arranged so as to cover the non-skin surface of the main body portion, and the hook member on the non-skin surface side of the main body portion is joined to the surface sheet. Maintain the state of the body being grouped. At this time, the post-processing member can be joined to the surface sheet in the core material arrangement area where the absorbent core material is arranged. The absorbent core material has high rigidity at the structural member of the absorbent article. By maintaining the state of agglomerated absorbent core material with higher rigidity, the absorbent article can be made difficult to expand and can be easily maintained in the agglomerated state. In addition, the main body adhesive part that joins the absorbent article to the wearing article during use is also supplementarily joined to the surface sheet. Therefore, the post-processing member can be joined to the surface sheet, and the body bonding part can also be joined to the surface sheet. It is possible to maintain the state of agglomeration of the main body at the time of disposal, and with the post-processing member, the absorbent article can be cleanly discarded.

According to a preferred aspect, in the width region, the body bonding portion and the post-processing member are arranged in the width direction at intervals. According to this aspect, the main body bonding part and the post-processing member are less likely to interfere, and it is possible to prevent the body bonding part and the post-processing member from being accidentally joined in the state before disposal.

According to a preferred aspect, the distance in the width direction between the main body bonding portion and the post-processing member is greater than the distance between the non-skin surface side of the main body bonding portion and the front end of the hook member The distance in the thickness direction is long. Since the hook member protrudes to the non-skin surface side, it may bend or fall when a force is applied. Since the separation distance between the post-processing member and the main body adhesive part is longer than the length of the hook member protruding toward the non-skin surface side with respect to the main body adhesive part, when the hook member falls, the hook member and the main body adhesive part are not easily contacted. Therefore, it is possible to suppress inconveniences such as accidental joining of the body bonding part 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 front end of the hook member is greater than the thickness between the non-skin surface of the main body and the non-skin surface of the main body bonding portion The distance in the direction is long. According to this aspect, the hook member protrudes more toward the non-skin surface side than the main body adhesive portion, and when the main body portion is massed with the skin surface side of the main body located inside, the hook member is more easily bonded to the surface sheet. Therefore, it is possible to maintain the agglomerated state at the time of disposal by the post-processing member, and it is possible to cleanly discard the absorbent article.

According to a preferred aspect, the length in the width direction of the body bonding portion is longer than the length in the width direction of the post-processing member. The main body adhesive part has the function of joining the main body with respect to the wearing article during use, and also has the function of auxiliary joining with the surface sheet during disposal. Generally, the bending rigidity of the body bonding part is lower than the bending rigidity of the post-processing member. Even if the length of the body bonding part is lengthened, it is not easy to cause discomfort when wearing. By increasing the length in the width direction of the main body bonding portion, it is possible to suppress discomfort and to more easily ensure the bonding force to the surface sheet at the time of disposal.

According to a preferred aspect, the area of the post-processing member is less than 20% of the entire area of the main body. According to this aspect, the area of the post-treatment member having the hook member is smaller than the area of the entire main body. Therefore, it is possible to suppress the rigidity of the absorbent article from increasing due to the post-treatment member, and it is possible to suppress discomfort during wearing.

According to a preferred aspect, the length in the width direction of the post-treatment member is 1/3 or less of the length in the width direction of the absorbent core material. According to this aspect, the length in the width direction of the post-processing member is 1/3 of the length in the width direction of the main body, and the post-processing member has a narrow width relative to the main body. It is easy to secure the area where the body bonding part is arranged on the outside in the width direction of the post-processing member. In addition, since the post-processing member has a narrow width, the width of the area where the surface sheet and the hook member contact is narrow, and the hook member temporarily bonded to the surface sheet is easily peeled off from the surface sheet. Therefore, after grouping in an unwanted form, the main body can be grouped again. In addition, the width of the post-processing member is narrow, so it is easy to fold tightly when the main body is folded in the width direction when the outer edge of the post-processing member is used as a base point at the time of disposal. Therefore, the absorbent article can be discarded in a tightly folded state.

According to a preferred aspect, the post-processing member is arranged to straddle the center in the width direction of the main body. According to this aspect, the center in the width direction of the main body can be joined by the post-processing member. Generally, as for the center in the width direction of the main body, the length in the front-rear direction of the main body is the longest. By joining the longest portion in the front-rear direction of the main body by the hook member, the entire area in the front-rear direction of the main body can be maintained in a grouped state. In addition, generally speaking, when the main body is grouped at the time of disposal, the center in the width direction of the main body is used as the base point. At this time, there is a post-processing member at the base point. Therefore, the post-processing member and the surface sheet can be unconsciously pressed in the direction toward each other during the operation of massaging the main body, and the hook member can be joined to Surface flakes.

According to a preferred aspect, the post-processing members are arranged in pairs with the center in the width direction of the main body part interposed. According to this aspect, it is possible to maintain a grouped state in the entire width direction of the main body by a pair of post-processing members that sandwich the center in the width direction of the main body.

Whether it is grouped from the front area or the rear area, it is easily covered by the surface sheet on the side of the grouping end. According to this aspect, in the area overlapping with the central area, the post-processing member can be joined to the surface sheet, can maintain the agglomerated state at the time of disposal, and the absorbent article can be cleanly discarded by the post-processing member.

According to a preferable aspect, a plurality of bending base points extending in the width direction are provided at positions closer to the outside in the front-rear direction than the post-processing member. According to this aspect, when the main body is grouped in the front-to-rear direction, the bending base can be used as the basis for grouping, and the user can easily perform the grouping operation. In addition, when clustering starts from a region closer to the outer side in the front-rear direction than the post-processing member, by clustering with the bending base portion as a base point, the entire main body can be clustered tightly.

According to a preferred aspect, the bending base portion includes a fold line used to fold the absorbent article so that the skin side faces each other. According to this aspect, it is easy to deform by the crease of the fold line so that the skin surface side approaches, and it becomes easy to group the main body part with the skin surface side inside.

According to a preferred aspect, the bending base portion is located at a position closer to the outside in the front and rear direction than the outer end edge of the absorbent core in the front and rear direction, and includes the compressed surface sheet and the back sheet In the obtained edge compression portion, the distance in the front-rear direction between the outer end edge in the front-rear direction of the absorbent core material and the edge compression portion is longer than the thickness of the absorbent core material. According to this aspect, the rigidity between the edge compression part and the outer edge of the absorbent core material is lower than that between the edge compression part and the absorbent core material, and it is easily deformed softly. When the area between the edge compression portion and the outer edge of the absorbent core material is shorter than the thickness of the absorbent core material, when the end edge compression portion side is clustered, the edge compression portion and the absorbent core material The area between the outer end edges is not easily deformed softly under the influence of the thickness of the absorbing core material, and it is not easy to make a base point for the start of agglomeration. However, since the distance between the edge compression portion and the outer edge of the absorbent core material is longer than the thickness of the absorbent core material, the edge compression portion and the absorbent core material are The area between the outer ends of the rim can be softly deformed, and it becomes easy to form the starting point of the clustering. In addition, when the end edge compression portion side is the end of the clustering, the area between the edge compression portion and the outer end edge of the absorbent core material is not affected by the rigidity of the absorbent core material, and is easily deformed softly and easily The thickness difference between the core material arrangement regions is deformed to form a smooth outer shape, and it becomes easy to pack the main body more tightly.

According to a preferred aspect, in the absorbent article, the fold lines used to fold the absorbent article in the front-rear direction are provided in plural at intervals in the front-rear direction, and the fold lines have the highest The first fold line near the end edge on one side in the front-rear direction of the absorbent article, and the second fold line closest to the end edge on the other side in the front-back direction of the absorbent article, for the post-processing The member is arranged in an area between the first fold line and the second fold line. According to this aspect, the area between the first fold line and the second fold line is between the start side and the end side of the grouping. Whether it is grouped from the front area or from the back area, it is easy It is covered by the surface sheet on the end side of the agglomeration. Therefore, by joining the post-processing member to the surface sheet at the time of disposal, the agglomerated state can be maintained, and the absorbent article can be cleanly discarded by the post-processing member.

According to a preferable aspect, the post-processing member is arranged so as not to cross at least one of the first fold line and the second fold line. According to this aspect, a crease based on a fold line is formed in the main body. In a state where the body part is massed so that the skin surface side is inside, the front side area and the back side area bordered by the fold line are deformed toward the skin surface side (inside) based on the fold line. If it deforms inward with the fold line as the boundary, the post-processing member and the surface sheet may separate, the hook member and the surface sheet may not be easily joined, or the temporarily joined hook member may fall off. By not crossing the fold line, it is possible to suppress the engagement state of the hook member from accidentally falling off due to the fold.

The covering sheet 40 of the present embodiment is composed of both the individual packaging sheet 41 and the release sheet 42. As shown in FIG. 3, the peeling sheet 42 is arrange|positioned on the non-skin surface side T2 of the hook member 31 of the post-processing member 30, and the individual packaging sheet 41 is arrange|positioned on the non-skin surface side T2 of the peeling sheet 42. Since the peeling sheet 42 is arranged between the hook member 31 and the individual packaging sheet 41, it is possible to prevent the individual packaging sheet 41 from being accidentally broken by the hook member 31.

The peel strength between the covering sheet 40 and the post-processing member 30 is lower than the peel strength between the post-processing member 30 and the non-skin surface of the main body portion 20. In more detail, in the individually packaged state, the covering sheet 40 is in contact with the hook member 31, and the peel strength between the covering sheet 40 and the hook member 31 is lower than the peel strength between the post-processing member 30 and the back sheet 22 . In other words, when unfolding from the individually packaged state, the covering sheet 40 can be peeled from the hook member 31 without peeling the post-processing member 30 and the back sheet 22. With such a structure, when unsealing from the individually packaged state, the covering sheet 40 can be separated from the main body 20 and the post-processing member 30 without peeling the post-processing member 30 from the main body 20.

In addition, the peel strength between the covering sheet 40 and the adhesive portion 50 is higher than the peel strength between the covering sheet 40 and the post-processing member 30. In more detail, in the individually packaged state, the covering sheet 40 is in contact with the main body adhesive portion 51, and the covering sheet 40 is in contact with the hook member 31. The peel strength between the covering sheet 40 and the main body adhesive portion 51 is higher than that of the covering sheet The peel strength between 40 and the hook member 31 is high. That is, the hook member 31 may be more easily peeled from the covering sheet 40 than the main body adhesive part 51 when unfolded from the individually packaged state. In the individually packaged state, the position shift of the covering sheet 40 can be suppressed by the bonding of the covering sheet 40 and the adhesive portion 50. In addition, since the hook member 31 easily peels off from the covering sheet 40, when the covering sheet 40 is separated from the main body portion 20 and the post-processing member 30, it is possible to prevent the post-processing member 30 from being caught on the covering sheet 40.

The peeling strength between the covering sheet 40 and the post-processing member 30 can be measured as follows. First, with regard to the absorbent article in the folded packaging state, the absorbent article is made into an unfolded state. The front side of the coated sheet and the front side of the main body were respectively clamped on a jig, and the peel strength in the longitudinal direction was measured by a tensile tester (manufactured by Instron). In the case where there are a plurality of coated sheets, the position where the plurality of sheets overlap is sandwiched by a clamp. After the evaluation was performed at a speed of 100 mm/min., the result obtained by converting the following area into N/25 mm was used as the peel strength between the covering sheet 40 and the post-processing member 30. In addition, when it is not bonded but only in contact, it is set to 0N/25mm.

In addition, the peel strength between the post-processing member 30 and the main body 20 can be measured in the following manner. For the absorbent article in the folded packaging state, the absorbent article is in the unfolded state. After the main body and the post-processing member are peeled from the coating sheet, the part where the hook member is attached is cut by a cutter. The main body part (the back sheet is fixed to a minimum) and the post-processing part member are respectively clamped on the jig, and the peel strength in the longitudinal direction is measured by a tensile tester. In addition, for products where the hook member is always adhered to the end, the part to be clamped to the jig is made by cold spraying or the like. However, in order to prevent the decrease in bonding strength caused by cold spraying, etc., make sure that more than 1/3 of the whole is the unaffected part. After the evaluation was performed at a speed of 100 mm/min., the result obtained by converting the subsequent area into N/25 mm was used as the peel strength between the post-processing member 30 and the main body 20.

The peel strength between the covering sheet 40 and the adhesive part 50 can be measured in the following manner. For the absorbent article in the folded packaging state, the absorbent article is in the unfolded state. The front side of the covering sheet and the front side of the main body were respectively clamped on a jig, and the peel strength in the longitudinal direction was measured with a tensile tester (manufactured by Instron). In the case where there are a plurality of coated sheets, the position where the plurality of sheets overlap is sandwiched by a clamp. After the evaluation was performed at a speed of 100 mm/min., the result obtained by converting the following area into N/25 mm was used as the peel strength between the covering sheet 40 and the adhesive portion 50.

The fold line of the absorbent article 1 for folding the absorbent article 1 in the front-rear direction L is in the front-rear direction, and is provided at intervals. The fold line extends along the width direction W and has a first fold line FL1 and a second fold line FL2. The first fold line FL1 is the edge closest to one side of the absorbent article 1 in the front-rear direction L, and the second fold line FL2 is the edge closest to the other side of the absorbent article 1 in the front-rear direction L. In the examples shown in Figures 1 and 2, the first fold line FL1 is closest to the rear edge of the absorbent article 1 among the plurality of fold lines, and the second fold line F2 is closest to the absorbent article among the plurality of fold lines The leading edge of 1. In addition, in a modified example, another fold line extending in the width direction W may be arranged between the first fold line FL1 and the second fold line FL2. The first fold line FL1 and the second fold line FL2 are lines used to fold the absorbent article 1 so that the skin surface side T1 of the absorbent article 1 is inside when the absorbent article is packaged (before use). The main body 20 and the covering sheet 40 of the absorbent article 1 are folded together, and the main body 20 is individually packaged by the individual packaging sheet 41. The crease line can be determined based on the position of the crease. In a form where the crease of the main body 20 is not easy to determine, the position of the fold line of the main body 20 and the post-processing member 30 is determined based on the crease of the covering sheet 40.

FIG. 5 is a diagram showing the absorbent article 1 in a packaged state in which the main body portion 20 is individually wrapped by the individual packaging sheet 41. Fig. 5(a) is a plan view of the 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 folded together in a state where the main body 20 is arranged on the individual packaging sheet 41 and the release sheet 42. As an example of the folded aspect, in a state where the main body portion 20 is arranged on the individual packaging sheet 41 and the release sheet 42, the rear edge side of the absorbent article 1 in the forward and backward direction L is set based on the first fold line FL1. The inner side is folded, and then the front end edge side of the absorbent article 1 is folded on the inner side in the front-rear direction with the second fold line FL2 as a base point. At this time, it is folded so that the skin surface side T1 of the main body part 20 may face each other. The front end of the folded area (specifically, the front end edge of the individual packaging sheet 41) with the second fold line FL2 as the base point is fixed to the individual packaging sheet 41 that has been folded with the first fold line FL1 as the base point by a belt member 45 on. By folding in this way, the main body part 20 is individually packaged by the individual packaging sheet 41. In addition, in the modified example, the belt member 45 may not be provided.

In the state where the absorbent article 1 has been folded, it is preferable that the surface sheet 21 and the post-processing member 30 do not contact each other. The absorbent article 1 of the present embodiment is in a folded state before use, and the surface sheet 21 is not arranged so as to cover the non-skin surface side T2 of the post-treatment member 30, and in a folded state before use, The post-processing member 30 and the surface sheet 21 do not abut, and the hook member 31 is not accidentally joined to the surface sheet 21. However, for the form in which there are three or more fold lines extending in the width direction W and the form in which the post-processing member 30 is arranged across the fold line in the front-rear direction L, there may be a cover in a folded state such as a packaged state. The surface sheet 21 is arranged on the non-skin surface side T2 of the post-processing member 30. For such a form, it is preferable to arrange the structural member constituting the absorbent article 1 between the hook member 31 and the surface sheet 21. This structural member is, for example, the covering sheet 40. In the folded state, the structural member is arranged between the surface sheet 21 and the hook member 31 so that the surface sheet 21 and the hook member 31 do not abut. Therefore, it is possible to suppress a problem that the hook member 31 is intentionally joined to the surface sheet 21 before use.

Next, an example of the disposal form of the absorbent article 1 will be explained based on FIG. 6. Since excrement is attached to the surface sheet 21 after use, when the user discards the absorbent article 1, the skin surface side T1 of the main body portion 20 may be rolled inside and discarded. At this time, as shown in FIG. 6(a), the main body 20 and the post-processing member 30 are grouped from the front or rear edge of the main body 20 in the front-rear direction L. The non-skin surface side T2 of the portion of the main body portion 20 where the bundling starts abuts against the surface sheet 21, and the main body portion 20 is blobed 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. If the main body 20 and the post-processing member 30 are further grouped in the front-rear direction L from the state shown in FIG. 6(a), the hook member 31 will abut the surface sheet 21. The umbrella portion 312 of the hook member 31 is hooked to the fibers of the surface sheet 21 so that the hook member 31 is joined to the surface sheet 21. With the post-processing member 30, the absorbent article 1 can be discarded in a clean state in which the surface to which the excrement is attached is inside. Since the hook member 31 is hooked between the fibers of the surface sheet 21 to achieve a bonded state, even when the surface sheet 21 is wet due to the adhesion of body fluids such as menstrual blood, it is difficult to obtain the bonding force between the adhesive portion 50 and the surface sheet 21 In this case, the post-processing member and the surface sheet can also be joined. In particular, after the adhesive part is attached to underwear etc., the joining force is reduced, and the surface sheet is in a wet condition. Therefore, the surface sheet and the adhesive part 50 are not easily joined. Therefore, the post-processing member 30 can be used for joining. . In addition, the operation of joining the hook member 31 of the post-processing member 30 to the surface sheet 21 can be performed in the process of massing the main body portion 20, and no additional operations such as pulling the post-processing member 30 for joining are necessary. Therefore, even in the case where the user disposes without being particularly conscious, the post-processing member 30 can maintain the massed state of the main body 20.

In a state where the absorbent article 1 has been agglomerated, the main body adhesive portion 51 also abuts the surface sheet 21. The main body adhesive part 51 has a function of joining the main body part 20 to a wearing article during use, and has an adhesive force to some extent even after the main body part 20 is removed from the wearing article. The main body bonding portion 51 is also auxiliary bonded to the surface sheet 21. Therefore, the post-processing member 30 can be joined to the surface sheet 21, and the body bonding portion 51 can also be joined to the surface sheet 21. The post-processing member 30 and the body bonding portion 51 are arranged in the core material arrangement region R23. The absorbent core 23 is a structural member of the absorbent article 1, and has high rigidity. By maintaining the absorbent core 23 having a relatively high rigidity in the agglomerated state, the main body part 20 is not easily expanded and is easily maintained in the agglomerated state.

At least a part of the main body adhesive portion 51 is arranged in a width region RW extending in the width direction W from the post-processing member 30. The width area RW is an area extending from the entire area in the front-rear direction L of the post-processing member 30 in the width direction. In a form in which a plurality of post-processing members 30 are arranged, plural width areas are also provided. In FIG. 2, the width area RW is shown with diagonal lines. By arranging the body bonding part 51 in the width region RW, both the body bonding part 51 and the post-processing member 30 are arranged on an arbitrary virtual line extending in the width direction W. On this imaginary line, both the main body adhesive portion 51 and the post-processing member 30 are joined to the surface sheet 21, and it becomes easier to maintain the agglomerated state. It is more desirable that the main body bonding portion 51 and the hook member 31 are arranged on an arbitrary virtual line extending in the width direction W.

As shown in FIG. 4, in the width area RW, the body bonding part 51 and the post-processing member 30 are arranged in the width direction W with an interval therebetween. The body bonding part 51 and the post-processing member 30 are less likely to interfere, and it is possible to prevent the body bonding part 51 and the post-processing member 30 from being accidentally joined before disposal. In addition, in the modified example, the body bonding portion 51 and the post-processing member 30 may be adjacent to each other in the width direction W. In this modification, it is preferable that the main body bonding portion 51 and the hook member 31 are arranged in the width direction W with an interval therebetween.

As shown in FIG. 4, the distance D11 in the width direction W between the main body adhesive portion 51 and the post-processing member 30 is greater than the distance between the non-skin surface side T2 of the main body adhesive portion 51 and the front end 31P of the hook member 31 The distance D12 in the thickness direction T is long. The front end 31P of the hook member 31 is the most protruding end edge of the hook member 31, and in this embodiment, it is the edge of the umbrella portion 312 on the non-skin surface side T2. The surface on the non-skin surface side T2 of the main body adhesive portion 51 is the surface of the main body portion 20 that is in contact with the post-processing member 30, and is the non-skin surface of the back sheet 22 in this embodiment. In addition, the distance D12 may also be determined by (the thickness T30 of the post-processing member relative to the non-skin side surface of the main body portion 20 (the non-skin side surface of the back sheet 22))-(the thickness of the main body adhesive portion 51 relative to the main body portion 20 The thickness T51) of the surface on the non-skin side (the non-skin side of the back sheet 22) is calculated. The hook member 31 protrudes toward the non-skin surface side T2, and may bend or fall when a force is applied. Since the distance between the post-processing member 30 and the main body adhesive portion 51 is greater than the length (D12) that the tip 31P of the hook member 31 protrudes toward the non-skin surface side T2 relative to the main body adhesive portion 51, when the hook member 31 falls , The hook member 31 and the body bonding part 51 are not easy to contact. Therefore, it is possible to suppress inconveniences such as accidental joining of the main body adhesive portion 51 and the post-processing member 30 in the state before disposal. Furthermore, in the modified example, the body bonding part 51 may not be provided.

The distance T30 in the thickness direction T between the non-skin surface of the main body portion 20 and the tip of the hook member 31 is greater than the distance in the thickness direction T between the non-skin surface of the main body portion 20 and the non-skin surface of the main body adhesive portion 51 T51 is long. The distance T30 in the thickness direction T between the non-skin surface of the main body 20 and the front end of the hook member 31 is the thickness of the post-processing member 30, and specifically, is 0.05 mm or more and 1.0 mm or less. If it is less than 0.05 mm, it is difficult to obtain sufficient force for joining the post-processing member 30 to the surface sheet 21. Moreover, if it is longer than 1.0 mm, when the post-processing member 30 comes into contact with the skin, the unpleasant feeling on the skin may increase. In addition, the distance T51 in the thickness direction T between the non-skin surface of the main body portion 20 and the non-skin surface of the main body adhesive portion 51 is the length in the thickness direction T of the main body adhesive portion 51, specifically, 0.1 mm or less. The hook member 31 protrudes further toward the non-skin surface side T2 than the main body adhesive portion 51. When the main body portion 20 and the post-treatment member 30 are grouped with the skin surface side T1 of the main body portion 20 inside, the hook member 31 is easier Joined to the surface sheet 21. Therefore, it is possible to maintain the agglomerated state by the post-processing member 30 at the time of disposal, and the main body 20 can be cleanly discarded.

The length in the width direction W of the body bonding portion 51 is longer than the length in the width direction W of the post-processing member 30. As in this embodiment, in the form in which the main body bonding portion 51 is arranged in a plurality of rows at intervals in the width direction W, the length of the body bonding portion 51 in the width direction W is the length of the body bonding portion 51 in the width direction W The length obtained by adding up the length. The main body adhesive part 51 has a function of joining the main body part 20 to a wearing article during use, and also has a function of auxiliary joining to the surface sheet 21 during disposal. Generally, the flexural rigidity of the main body adhesive part 51 is lower than that of the post-processing member 30, and even if the length of the main body adhesive part 51 is increased, discomfort during wearing is less likely to occur. By increasing the length in the width direction W of the main body bonding portion 51, it is possible to suppress discomfort and to more easily ensure the bonding force to the surface sheet 21 at the time of disposal. Similarly, the length in the front-rear direction L of the main body bonding portion 51 is longer than the length in the front-rear direction L of the post-processing member 30. As in the second embodiment, in the form where a plurality of rows of main body bonding parts 51 are arranged at intervals in the front-rear direction L, the length of the body bonding part 51 in the front-rear direction L is the length of the front-back direction L of each body bonding part 51 The length obtained by adding up the lengths above. By increasing the length in the front-rear direction L of the main body adhesive portion 51, it is possible to suppress discomfort and more easily ensure the bonding force with respect to the surface sheet 21 at the time of disposal.

The post-processing member 30 may be provided in a size necessary to suppress the uncomfortable feeling during wearing and ensure the bonding force to the surface sheet 21. The length in the front-rear direction L of the post-processing member 30 is longer than the thickness of the absorbent core 23 and shorter than the length in the front-rear direction of the absorbent core. The length is 80mm. Since the length of the post-processing member 30 in the front-rear direction L is longer than the thickness of the absorbent core material, it is possible to suppress the 21-point contact between the post-processing member 30 and the surface sheet when the body portion 20 is massed, ensuring post-processing The contact area between the member 30 and the surface sheet 21 is used. In addition, the length of the post-treatment member 30 in the front-rear direction L is shorter than the length of the absorbent core in the front-rear direction, so that the rigidity of the post-treatment member 30 can be suppressed from being transmitted to the skin surface of the main body, and discomfort can be reduced. The length in the width direction W of the post-processing member 30 is 1 mm or more and less than or equal to the length in the width direction of the absorbent core. The length in the width direction W of the post-processing member 30 is 1 mm or more, making it easy to ensure the bonding strength with respect to the surface sheet. In addition, since the length in the width direction W of the post-processing member 30 is smaller than the length in the width direction of the absorbent core, the main body bonding part can be arranged in the width area, and the main body part can be stably joined to the wearing article. It is more preferable that the length in the width direction of the post-processing member 30 is 5 mm or more and 35 mm or less, and the length in the width direction W of the post-processing member 30 of the present embodiment is 15 mm. The post-processing member can be produced stably, and the body bonding part can be easily arranged in the core material arrangement area, and the body part can be stably joined to the wearing article. The area of the post-processing member 30 is less than 20% of the entire area of the main body 20. Since the area of the post-treatment member 30 having the hook member 31 is smaller than the area of the entire main body portion 20, it is possible to suppress the increase in rigidity of the absorbent article 1 due to the post-treatment member 30, and it is possible to suppress discomfort during wearing sense.

The length in the width direction W of the post-processing member 30 is 1/3 or less of the length in the width direction of the absorbent core 23. In the aspect 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 1/3 relative to the maximum length in the width direction of the absorbent core 23. 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 where the main body adhesive portion 51 is arranged on the outside in the width direction W of the post-processing member 30. In addition, since the post-processing member 30 has a narrow width, the width of the area where the surface sheet 21 and the hook member 31 contact is narrow, and the temporarily joined hook member 31 is easily peeled from the surface sheet 21. Therefore, after grouping in an unwanted form, the main body part 20 can be grouped again. In addition, since the post-processing member 30 has a narrow width, it is easy to fold tightly when the main body portion 20 is folded in the width direction when the outer edge of the post-processing member 30 is used as a base point at the time of disposal. Therefore, the main body 20 can be discarded in a tightly folded state.

The post-processing member 30 is arranged across the center 20CW in the width direction W of the main body 20. The center 20CW in the width direction W of the main body portion 20 can be joined by the post-processing member 30. Generally, with respect to the center in the width direction W of the main body portion 20, the length in the front-rear direction L of the main body portion 20 is the longest. The hook member 31 engages the longest portion in the front-rear direction L of the main body 20, so that the entire area in the front-rear direction L of the main body 20 can be maintained in a grouped state. In addition, in general, when the main body portion 20 is grouped at the time of disposal, the center 20CW in the width direction of the main body portion 20 is grouped as a base point. At this time, since the post-processing member 30 is located at the base point, it is possible to unconsciously press the post-processing member 30 and the surface sheet 21 in the direction toward each other during the operation of massaging the main body 20. The hook member 31 can be joined to the surface sheet 21. In a modified example, the post-processing member 30 may be arranged in a pair with the center in the width direction W of the main body 20 interposed therebetween. The pair of post-processing members 30 that sandwich the center 20CW in the width direction W of the main body 20 can maintain the state of being grouped over the entire width in the width direction W of the main body 20. The length in the width direction W that can be joined by the post-treatment member 30 can be secured, and therefore, it is particularly ideal for absorbent articles having a long length in the width direction W.

The post-processing member 30 is provided at least in a region overlapping with the central region S2. The central area S2 is located between the start side and the end side of the grouping. Whether it is grouped from the front area S1 or the back area S3, it is easy to be the surface sheet 21 on the side of the grouping end. cover. In the area overlapping with the central area S2, by joining the post-processing member 30 and the surface sheet 21, the body part 20 can be maintained in a state of agglomeration during disposal, and the post-processing member 30 can cleanly absorb Item 1 is discarded. In addition, the post-processing member 30 may be arranged across the center in the front-rear direction of the main body 20.

A plurality of bending base points 80 extending in the width direction are provided at positions closer to the outside in the front-rear direction L than the post-processing member 30. The bending base portion 80 is a base point when the main body portion 20 is bent in the front-rear direction L. The base portion 80 is bent so that the main body portion 20 can be easily bent due to the difference in rigidity, thickness, and basis weight. When the main body portion 20 is grouped in the front-rear direction L, the bend base portion 80 can be used as the basis for grouping, and the user can easily perform the grouping operation. At this time, since the deformation base point when the main body portion 20 is grouped extends in the width direction, it is easy to group the entire width direction W of the main body portion 20 in the front-rear direction L. In addition, when the agglomeration starts from a region closer to the outside in the front-rear direction L than the post-processing member 30, the whole body portion 20 can be tightly agglomerated by using the bending base portion 80 as the basis for the agglomeration. .

At least one of the area on the front side and the area on the rear side of the post-processing member 30 may be provided with a plurality of bending base points 80. It is preferable that a plurality of bending base points 80 are respectively provided in both the front side region and the rear side region of the post-processing member 30. It becomes easy to group the whole body part 20 in the front-back direction L. In addition, in a structure in which a plurality of bending base points 80 are provided at intervals in the front-rear direction L, each functions as a bending base point 80. However, when the distance between the bending base points 80 in the front-rear direction L is 5 mm or less, since it functions as an integrated deformation base point, a plurality of bending base points are arranged at intervals of 5 mm or less as a whole It constitutes a bending base point.

The bending base portion 80 is a compressed portion including at least one of the compressed surface sheet 21 and the absorbent core 23. In more detail, the front end edge and the rear end edge of the compression portion constitute the bending base point portion 80. In addition, in a structure in which a plurality of compression parts are staggered in the front-rear direction L, the front end edge and the rear end edge of each compression part constitute the bending base point 80. The compression portion constituting the bending base portion 80 may be a portion obtained by compressing at least the absorbent core 23 or a portion obtained by compressing at least the surface sheet 21. In the main body portion 20 of this embodiment, at a position closer to the outside in the front-rear direction L than the outer end edge in the front-rear direction L of the absorbent core 23, an end formed by compressing the front sheet 21 and the back sheet 22 is provided. Edge compression part 27. The edge compression portion 27 constitutes a bending base point portion 80. Compared with the area where the compression portion is not formed, the compression portion has higher rigidity and thinner thickness. The compression portion constitutes the bending base portion 80, so that the main body portion 20 can be compacted easily due to the difference in thickness and rigidity. It is preferable that the compression part is recessed from the skin surface side T1 toward the non-skin surface side T2. The user usually masses the main body 20 so that the skin surface side T1 to which excrement is attached is inside when discarding. Since the compression part is recessed from the skin surface side T1 toward the non-skin surface side T2, it is easy to deform so that the skin surface side T1 approaches, and it becomes easy to cluster the main body part 20 so that the skin surface side T1 may be inside.

The bending base point portion 80 includes a base weight change portion. The basis weight change portion is a portion where the basis weight of the absorbent material of the absorbent core 23 differs from the area adjacent in the front-rear direction L. Specifically, the front end edge and the rear end edge of the absorbent core 23 constitute a basis weight change part. The front and rear edges of the high basis weight portion also constitute the basis weight change portion. The low basis weight varies depending on the length in the front-rear direction. In a case where the length in the front-rear direction of the low basis weight portion is less than 20 mm, the center of the low basis weight portion in the front-rear direction constitutes the basis weight change portion. When the length in the front-rear direction of the low basis weight portion is 20 mm or more, the front end edge and the rear end edge of the low basis weight portion constitute the basis weight change portion. Moreover, when a plurality of low basis weight portions are provided separately in the front-rear direction and the plurality of low basis weight portions are connected, the low basis weight portions separated in the front-rear direction respectively constitute the basis weight change portions. The basis weight change part constructed in this way is that the basis weight of the absorbent material is different from the area adjacent in the front-rear direction, and the thickness and rigidity of the absorbent core 23 are different. The basis weight change portion constitutes the bending base point portion, which makes it easy to compact the absorbent article due to the difference in thickness and rigidity.

The bending base portion 80 includes a low basis weight portion provided on the absorbent core 23 as a basis weight change portion. Compared with the region where the low basis weight part is not formed, the low basis weight part has higher rigidity and thinner thickness. The low basis weight constitutes the bending base portion 80, so that the main body portion 20 can be easily formed by the difference in thickness and rigidity. The low basis weight portion as the basis weight change portion is preferably provided along the width direction W. When viewed in the front-rear direction L, the length in the front-rear direction of the low basis weight portion is longer on the skin surface side than the non-skin side. Since the length in the front-rear direction of the skin surface side of the low-basis weight portion is longer than the length in the front-rear direction of the non-skin surface side of the low-basis weight portion, it is easily deformed to approach the skin surface side T1, and it becomes easy to The main body 20 is grouped with the side T1 on the inside.

The bending base portion 80 includes a first fold line FL1 and a second fold line FL2 for folding such that the skin surface side T1 of the absorbent article 1 faces each other. In the structure in which the folding line has a certain length in the front-rear direction L, the front and rear edges of the first folding line F1 and the front and rear edges of the second folding line F2 constitute a bending base point portion 80. Therefore, it is easy to deform so that the skin surface side approaches by the creases of the 1st fold line FL1 and the 2nd fold line FL2, and it becomes easy to cluster the main body part 20 so that the skin surface side may be inside. That is, the bending base point portion 80 is constituted by at least any one of a compression portion, a basis weight change portion, and a folding line. By providing the bending base portion 80 in this way, the user can easily roll the absorbent article 1 in the front-rear direction, and it is easy to discard the absorbent article 1 in a clustered state.

The shape of the bending base portion 80 is not limited, and it may be a dot shape, a belt shape, an arc shape, or a polygon shape. The bending base point portion 80 has a first bending base point portion and a second bending base point portion. The length in the width direction of the first bending base point portion is longer than the length in the front-rear direction of the first bending base point portion. The length in the front-rear direction of the second bending base point portion is longer than the length in the width direction W of the second bending base point portion. The main body portion 20 becomes easy to bend in the front-rear direction L using the first bending base point as a base point, and it is also easy to bend in the width direction W using the second bending base point as a base point. The number of the first bending base point portions of the entire absorbent article is larger than the number of the second bending base point portions. When the main body portion 20 is rounded, it is easier to round in the front-rear direction than in the width direction. Therefore, it is easy to pack the absorbent article more tightly in the front-to-rear direction, and it is easier to maintain the balled state.

There are three or more bending base points 80 ranging from the outer end edge of the main body 20 in the front-rear direction to 1/3 of the length of the main body 20 in the front-rear direction. The circumference of the main body portion 20 in a state where the main body portion 20 is grouped in the front-rear direction L is usually about 1/3 of the length of the main body portion 20 in the front-rear direction L. 1/3 of the length in the front-rear direction L of the main body portion 20 becomes the area where the grouping starts or the area where the grouping ends. By providing three or more bending base points 80 in this part, it becomes easier to maintain the agglomerated state.

The distance D27 (refer to FIG. 1) in the front-rear direction between the outer end edge in the front-rear direction of the absorbent core material 23 and the end edge compression portion 27 is longer than the length T23 (refer to FIG. 3) in the thickness direction of the absorbent core material . Compared with the edge compression part 27 and the absorbent core material 23, the rigidity between the edge compression part 27 and the outer edge of the absorbent core material 23 is lower, and it is easy to deform softly. If the area between the edge compression portion 27 and the outer edge of the absorbent core material 23 is shorter than the length T23 in the thickness direction of the absorbent core material 23, when the body portion 20 is massed from the edge compression portion 27 side The area between the edge compression portion 27 and the outer edge of the absorbent core material 23 is not easily deformed softly under the influence of the thickness of the absorbent core material 23, and becomes difficult to serve as a starting point for clustering. However, since the distance between the edge compression portion 27 and the outer edge of the absorbent core 23 is longer than the thickness of the absorbent core 23, when the edge compression portion 27 begins to cluster from the edge compression portion 27 side, the edge compression portion 27 The area between the outer edge of the absorbent core 23 and the absorbent core 23 can be softly deformed and is easily used as a starting point for clustering. In addition, when the end edge compression portion 27 side is the end of the clustering, the area between the edge compression portion 27 and the outer edge of the absorbent core 23 is not affected by the rigidity of the absorbent core 23 and easily deforms softly, and It is easy to deform to form a smooth outer shape by the thickness difference with the core material arrangement area, and it is easy to make the main body portion 20 more compactly grouped.

The post-processing member 30 is arranged in the area between the first fold line FL1 and the second fold line FL2. At least a part of the post-processing member 30 may be arranged between the first fold line FL1 and the second fold line FL2, and the post-processing member 30 may be arranged across the first fold line FL1 and the second fold line FL2. The area between the first fold line FL1 and the second fold line FL2 is located between the beginning of the grouping and the end of the grouping, regardless of whether it is grouped from the front area S1 or from the back area S3. It is easily covered by the surface sheet 21 on the end side of the agglomeration. Therefore, by joining the post-processing member 30 to the surface sheet 21 at the time of disposal, the agglomerated state can be maintained, and the absorbent article can be cleanly discarded by the post-processing member 30.

The post-processing member 30 is arranged so as not to cross at least one of the first fold line FL1 and the second fold line FL2. A crease based on a fold line is formed in the main body portion 20. In the state of being grouped so that the skin surface side T1 is on the inside, the area on the front side and the area on the back side bordered by the fold line are deformed toward the skin surface side (inside) with the fold line as a base point. If it deforms inwardly with the fold line as the boundary, the post-processing member 30 and the surface sheet 21 may separate, the hook member 31 and the surface sheet 21 may not be easily joined, or the temporarily joined hook member 31 may fall off. By not crossing the fold line, it is possible to prevent the hook member 31 from accidentally falling off due to the crease. In addition, by forming the body part 20 from the side of the fold line not spanned by the post-processing member 30 when the main body part 20 is formed, it does not receive the reaction force generated by the post-processing member 30 to return to a flat state and can be formed. It is easy to be firmer and clump with weaker force. In addition, by arranging the post-processing member 30 so as to straddle the fold line covered by the surface sheet 21 at the time of grouping, the hook member 31 and the surface sheet 21 can be easily joined by the reaction force generated by the post-processing member 30.

As shown in FIG. 4, the thickness T31 of the hook member 31 is thicker than the thickness T21 of the surface sheet 21. The thickness T31 of the hook member 31 is the thickness of the shaft portion 311 plus the thickness of the umbrella portion 312. When the hook member 31 is pressed toward the surface sheet 21, the tip of the hook member 31 penetrates the surface sheet 21, and the umbrella portion 312 of the hook member 31 is easily hooked on the surface sheet 21. As a result, the hook member 31 is joined to the surface sheet 21, and the hook member 31 maintains the massed state, and it is easy to be cleanly discarded by the post-processing member 30.

In addition, in a modified example, the thickness T31 of the hook member 31 may be thinner than the thickness T21 of the surface sheet 21. When the hook member 31 is pressed toward the surface sheet 21, the umbrella portion 312 of the hook member 31 stays inside the surface sheet 21, and the umbrella portion 312 of the hook member 31 becomes easy to hook into the fibers of the surface sheet 21. As a result, the hook member 31 is joined to the surface sheet 21, and the hook member 31 maintains the massed state, and it is easy to be cleanly discarded by the post-processing member 30.

The hook member 31 protrudes from the base sheet 35 toward the non-skin surface side T2, and is arranged in a region overlapping the bonding area where the base sheet 35 and the main body portion 20 are bonded in the thickness direction T. The bonding area in this embodiment is provided in the entire area where the base sheet 35 is arranged. The hook member 31 provided in the joining area is unlikely to float on the back sheet 22, and its position is not easily shifted. Therefore, the hook member 31 is easily hooked to the surface sheet 21 in the process of massing the main body 20 at the time of disposal. In addition, since the position of the hook member 31 is not easily shifted, as long as the hook member 31 is joined to the surface sheet 21, the joined state can be easily maintained.

When viewed in plan from the non-skin surface side T2 of the absorbent article 1, the color difference ΔE between the non-skin surface of the main body portion 20 and the post-treatment member 30 is 3.0 or more. Since the color difference ΔE between the non-skin surface of the main body portion 20 and the post-processing member is 3.0 or more, the user can easily recognize the main body portion 20 and the post-processing member 30 as different bodies, and easily recognize the difference in the post-processing member 30 exist. In addition, in a form in which the non-skin surface of the main body 20 has multiple colors, such as a method in which printing is applied to the back sheet 22, the color difference ΔE between the color of the region occupying the largest area and the post-processing member 30 is 3.0 or more. As a result of various studies conducted by the applicant, it is known that the user usually easily recognizes the two areas as different areas when the color difference ΔE is 3.0 or more. Since the color difference ΔE between the non-skin surface of the main body portion 20 and the post-treatment member 30 is 3.0 or more, the user can easily recognize the main body portion 20 and the post-treatment member 30 as different bodies, and easily recognize the post-treatment member 30 The presence. The user can recognize the post-processing member 30 and group the main body 20 to easily join the post-processing member 30 to the surface sheet 21.

In addition, in a state where the individual packaging sheet 41 is individually packaged, the color difference ΔE between the adjacent area adjacent to the post-processing member 30 and the area where the post-processing member 30 is arranged is 3.0 or more. In the state of packaging by the individual packaging sheet, the user can easily recognize the presence of the post-processing member 30. The user can recognize the post-processing member 30, open the individual packaging sheet 41, and use the absorbent article. Furthermore, for the structure in which the individual packaging sheet 41 and the peeling sheet 42 are arranged on the non-skin surface side of the main body 20, the identification of the processing member after the individual packaging sheet 41 and the peeling sheet 42 are interposed may be conspicuous to the adjacent area. .

The color difference ΔE between the main body 20 and the post-processing member 30 and the color difference ΔE between the adjacent area and the post-processing member 30 can be achieved by using the market for the two points (two areas) to be measured. Color measurement is performed by a commercially available color meter, and the value obtained by digitizing the color space of CIE1976 (L*a*b*) specified in JIS Z 8729 is compared. Specifically, when the difference in L* value between two points as the measurement object is ΔL*, the difference in a* is Δa*, and the difference in b* value is Δb*, the color difference ΔE=[(ΔL *) ² +(Δa*) ² +(Δb*) ² ]1/2 to find out.

The flexural rigidity of the post-processing member 30 is lower than the flexural rigidity of the area where the top sheet 21, the back sheet 22, and the absorbent core 23 overlap. When the absorbent article 1 is used, the post-treatment member 30 is arranged on the non-skin surface side T2 of the main body portion 20, and the post-treatment member 30 indirectly touches the skin. At this time, since the bending rigidity of the post-treatment member 30 is low, it is possible to suppress the discomfort caused to the wearer.

Furthermore, the flexural rigidity of the post-processing member 30, the flexural rigidity of the back sheet 22, the absorbent core 23, the top sheet 21, the back sheet 22, and the absorbent core 23, can be achieved by following the standard specifications The measurement is carried out by the Taber method specified in JIS P-8125. For example, first, a test piece having a width of 25 mm and a length of 38 mm is taken from the member (sheet) to be the measurement target. Next, the thickness of the test piece is measured with a thickness meter (for example, 44mmφ 3g/m ² manufactured by PEACOCK). Next, the test piece was set in a Taber rigidity testing machine of Yasuda Seiki. Next, the test piece was inserted between the rollers of the Taber rigidity testing machine, and the nip interval was matched with the thickness of the test piece to clamp it. Furthermore, align the upper end of the test piece with the upper surface of the clamp. The roller adjusted the distance between the roller and the test piece to about 0.5 mm without pressing the test piece. Rotate the test piece bending device of the Taber rigidity testing machine, stop the rotation of the bending device at the point where the 15-degree scale of the test piece bending device coincides with the pointer of the load vibrator, and read the indicator of the vibrator at this time Load scale. The load vibrator is immediately rotated in the opposite direction, the load scale is read in the same way, and the average value of the load scale in the left and right directions is obtained. In addition, the auxiliary weight is arbitrarily selected so as to indicate that the load scale is within the range of 15% to 85% of the maximum scale. Therefore, the bending rigidity (stiffness (g･cm)) of the test piece is calculated according to the calculation formula of "stiffness (g･cm)=average of load scale×10×value of weight". Moreover, when the length in the width direction of the sample is less than 25 mm, the data measured by the maximum width of the sample is converted into N/25 mm. In addition, the bending rigidity was measured 3 times, and the average value was taken.
