[Form for carrying out the invention]

(1) Outline of Embodiment From the description of this specification and the attached drawings, at least the following matters are understood.

An absorbent article of one aspect has: a front-rear direction; a width direction perpendicular to the front-rear direction; a main body having a surface sheet, a back sheet, and an absorbent core; and a belt sheet member for post-processing, the main body portion There are: a first region located on one side of the front-rear direction with respect to the center of the main body part in the front-rear direction; and a second region located on the other side of the front-rear direction with respect to the center of the main body part in the front-rear direction region, the absorbent article, wherein a plurality of bending base point portions serving as base points for bending the main body portion in the front-rear direction are provided in each of the first region and the second region, and the belt sheet member is It is fixed to the said 1st area, and the average interval of the said bending base point part of the said 2nd area is shorter than the average interval of the said bending base point part of the said 1st area.

The user lumps the absorbent article from the second region side at the time of disposal, and the absorbent article in the lumped state is fixed by the belt sheet member. At this time, since the average interval of the bending base point portions of the second region located on the inner side is short in the state after the agglomeration, it is possible to form the dough tightly. In addition, since the first region located on the outer side is also provided with a plurality of bending base points in the state after the agglomeration, both the first region and the second region can be easily agglomerated, and it is easy to maintain the shape after the agglomeration. state. Therefore, the absorbent article can be disposed of cleanly by the belt sheet member for post-processing, while maintaining the absorbent article in a tightly spheroidized state.

According to a desirable aspect, the number of the bending base point portions in the second region is greater than the number of the bending base point portions in the first region.

According to the absorbent article of one aspect, since the number of bending bases is large in the second region located inside in the swelled state, a large number of deformations are formed inside the swelled state base point, and easier to compact.

An absorbent article of another aspect has: a front-rear direction; a broadside direction perpendicular to the front-rear direction; a body portion having a surface sheet, a back sheet, and an absorbent core; and a belt sheet member for post-processing, the body portion It has a first region located on one side of the front-rear direction with respect to the center of the main body portion in the front-rear direction, and a second region located on the other side of the front-rear direction with respect to the center of the main body portion in the front-rear direction. The absorbent article is characterized in that a plurality of bending base point portions serving as base points for bending the main body portion in the front-rear direction are provided in each of the first area and the second area, and the tape sheet is A member is fixed to the said 1st area|region, and the average interval of the said bending base point part of the said 1st area is shorter than the average interval of the said bending base point part of the said 2nd area.

The user lumps the absorbent article from the second region side at the time of disposal, and the absorbent article in the lumped state is fixed by the belt sheet member. At this time, the 1st area|region located on the outer side after agglomeration is rolled up along the part located on the inside in the state after agglomeration. Since the average interval of the bending base point portions of the first region is short, the first region located on the outer side in the state after being agglomerated can be bent at short intervals. Therefore, even if unevenness is formed on the outer surface in the state where the second region is agglomerated, the first region is easily agglomerated into a circular shape. In addition, since the second region located on the inner side is also provided with a plurality of bending base points in the state after the agglomeration, both the first region and the second region can be easily compacted by the bending base points. And it is easy to maintain the state after grouping. Therefore, the absorbent article can be disposed of cleanly by the belt sheet member for post-processing, while maintaining the state after the agglomeration.

According to a desirable aspect, the number of the bending base point portions in the first region is greater than the number of the bending base point portions in the second region.

According to the absorbent article of another aspect, since the number of the bending bases is large in the first region located on the outer side in the hulled state, a large number of bending base points are formed on the outer side of the hulled state. Deform the base point, and it is easier to maintain a compact state of agglomeration.

According to a desirable aspect, the first region is located on the rear side with respect to the center in the front-rear direction.

When a user generally lumps an absorbent article, the lump starts from the front end edge or the rear end edge of the absorbent article in the front-rear direction. Among them, about 80% of users start to roll up from the front end edge of the absorbent article. Therefore, it is desirable that the belt member is provided in a region located on the rear side with respect to the center in the front-rear direction.

According to a desirable aspect, the maximum length in the width direction of the first region is longer than the maximum length in the width direction of the second region.

In the state after the agglomeration, the maximum length in the width direction of the first region located on the outside is long, so the second region located on the inside in the state after the agglomeration can be covered by the first region located on the outside, and It becomes easier to maintain the state after grouping.

According to a desirable aspect, the said bending base point part includes at least a pressing part that presses the said absorbent core in the thickness direction.

The press section has higher rigidity and thinner thickness than the region in which the press section is not formed. By constituting the bending base portion by the pressing portion, the absorbent article can be easily compacted due to the difference in thickness and rigidity.

According to a desirable aspect, the said press part is recessed toward the non-skin opposing surface side from the skin opposing surface side.

Generally, a user lumps the absorbent article with the skin-opposing surface side on which the excrement adhered as the inside when throwing it away. Since the press part is dented from the skin-opposing surface side toward the non-skin-opposing surface side, the skin-opposing surface side is easily deformed so that the absorbent article can be easily lumped with the skin-opposing surface side as the inner side.

According to a desirable aspect, the said bending base point part contains the basis weight change part which differs in the basis weight of the absorbent material of the said absorbent core with respect to the adjacent area|region with respect to the said front-back direction.

The basis weight varying portion is different from the basis weight of the absorbent material in the region adjacent to the front-rear direction, and the thickness and rigidity of the absorbent core are different. By constituting the bending base portion by the basis weight change portion, the absorbent article can be easily compacted due to the difference in thickness and the difference in rigidity.

According to an ideal aspect, the basis weight changing portion is a low basis weight portion having a low basis weight with respect to a region adjacent to the front-rear direction, The aforementioned low basis weight portion is provided along the broadside direction, The length in the front-rear direction of the skin-opposing surface of the low basis weight portion is longer than the length in the front-rear direction of the non-skin-opposing surface of the low basis weight portion when viewed in cross section along the front-rear direction.

Generally, a user lumps the absorbent article with the skin-opposing surface side on which the excrement adhered as the inside when throwing it away. Since the length in the front-rear direction of the skin-opposing surface of the low basis weight portion is lower than the length in the front-rear direction of the non-skin-opposing surface of the basis weight portion, it is easy to deform the skin-opposing surface side in close proximity to form a The skin-opposing surface side is the inner side, and the absorbent article tends to be lumped together.

According to a desirable aspect, the said bending base part contains the crease which folded the skin-opposing surface of the said absorbent article so that it may oppose.

The skin-opposing surface side is easily deformed by the foldability of the crease, and the absorbent article is easily lumped with the skin-opposing surface side as the inner side.

According to an ideal aspect, the bending base point portion extends along the width direction.

The deformation base point at the time of lumping the absorbent article extends along the widthwise direction, and it becomes easy to lump the entire widthwise direction of the absorbent article in the front-rear direction.

According to a desirable aspect, the bending base point portion has a first bending base point portion whose length in the width direction is longer than the length in the front-rear direction, and a length in the front-rear direction is longer than that in the width direction. In the second bending base point portion having a longer length, the number of the first bending base point portion is larger than the number of the second bending base point portion.

Since the number of the 1st bending base point part is larger than the number of the 2nd bending base point part, when lumping an absorbent article, it becomes easier to lump in the front-back direction rather than the width direction. Therefore, it becomes easy to compactly compact the absorbent article in the front-rear direction, and it becomes easier to maintain the compacted state.

According to a desirable aspect, the bending base portion is provided in a range from an outer edge in the front-rear direction of the main body portion in the first region to 1/3 of the length of the main body portion in the front-rear direction. 3 or more.

The perimeter in the state where the main body portion is rounded in the front-rear direction is generally formed to be about 1/3 of the length in the front-rear direction of the main body portion. With respect to 1/3 of the length of the main body part in the front-rear direction, it is the part which becomes the surface located on the outer side in the state after agglomeration. By providing three or more bending base points in this part, it becomes easier to maintain the state after the agglomeration.

The absorbent article 10 can be fixed to wearing articles such as underpants by the adhesive portions 52 and 70 provided on the non-skin-opposing surface side of the back sheet 22 . Moreover, by the adhesive parts 52 and 70, after the use of the absorbent article 10, in the state in which the absorbent article 10 is rolled up, the belt sheet member 60 can be caught and the rolled state can be maintained. Therefore, the adhesive portions 52 and 70 can be used for both the application of fixing to the clothing and the application of the belt sheet member for post-treating.

The main body adhesive portion 70 is provided in a region overlapping with the absorbent core 23 in the thickness direction T of the absorbent article 10 . The main body adhesive portion 70 preferably extends continuously or intermittently toward the rear of the absorbent article 10 from at least the excretion opening opposing region S1. The main body adhesive portion 70 extends in the front-rear direction L, and may be provided in plural in the width direction W at intervals. In other forms, the main body adhesive portion 70 extends in the widthwise direction W, and a plurality of them may be provided at intervals in the front-rear direction. The hip flap adhesive portion 52 is provided on the hip flap 50 .

The absorbent article 10 may also have creases extending in the widthwise direction W. As shown in FIG. The crease may be a crease that folds the skin-opposite sides of the absorbent article in a face-to-face manner. In the example shown in FIGS. 1 and 2 , the folds of the absorbent article 10 have a first fold F1, a second fold F2, and a third fold F3. The first fold line F1 is the fold line closest to the front end edge E1 of the absorbent article 10 . The second fold line F2 is the fold line closest to the rear end edge E2 of the absorbent article 10 . The third crease F3 is arranged between the first crease F1 and the second crease F2. In addition, four or more creases can be provided. The crease is a line for folding the absorbent article 10 with the skin-opposing surface side T1 of the absorbent article as the inner side when the absorbent article is packaged.

The fixing portion 62 may be provided at one end of the strip member 60 . The fixing portion 62 can be fixed to the main body portion 20 by adhesive means such as adhesive. The fixing portion 62 can be fixed to the back sheet 22 constituting the non-skin facing surface of the main body portion 20 .

Also, the strap member 60 may have a non-fixed portion 64 that is not fixed to the body portion 20 . The non-fixed portion 64 is not fixed to the back sheet 22 and is a portion where the user operates the belt sheet member 60 . More specifically, when the user uses the strap member 60 , the user pulls the non-fixed portion 64 or folds the non-fixed portion 64 from the fixed portion 62 as a base point, and then clamps the non-fixed portion 64 to the main body portion 20 . The non-fixed portion 64 may be configured to be elongated in the extension direction. The extension direction of the non-fixed portion 64 may be a direction from the fixed portion 62 toward the non-fixed portion 64 . In the configuration in which the fixed portion 62 and the non-fixed portion 64 are adjacent to each other in the front-rear direction L, the extension direction may be the front-rear direction L. Here, "elongation" includes elongation due to "elastic deformation" or "plastic deformation". As an example, the belt piece member 60 may be constituted by a stretchable sheet or a film.

The non-fixed part 64 of the band piece member 60 may be provided with a temporary fixing part (not shown). The temporary fixing portion is releasably joined to the back sheet 22 which is the non-skin-opposing surface of the main body portion 20 . By providing the temporary fixing portion, it is possible to suppress the non-fixing portion 64 from being curled or the non-fixing portion 64 being bent before the tape member 60 is used (at the time of manufacture or installation). The engagement force of the temporary fixing portion may be lower than that of the fixing portion 62 . Since the engagement force of the temporary fixing portion is lower than that of the fixing portion 62 , the user can easily peel off the temporary fixing portion when using the tape member 60 , and can grasp the non-fixing portion 64 and operate the tape member 60 . As for the fixing means of the temporary fixing part, there can be exemplified: adhesive, embossing, thermal fusion, ultrasonic fusion, and the application amount (area, basis weight) of the adhesive can be reduced more than the fixing part 62, or comparable. The fixed portion 62 further weakens the pressing of the embossing process. Moreover, the temporary fixing part may be comprised by the embossing of the outer edge of a main-body part.

The belt sheet member 60 is configured to maintain the rolled-up state of the absorbent article 10 by being stuck to the body portion 20 rolled up with the skin-opposing surface side of the absorbent article inward when the absorbent article 10 is discarded. The non-fixed portion 64 of the strip member 60 is configured to be able to be latched with respect to the body portion 20 . The structure in which the non-fixed portion 64 is clamped to the main body portion 20 may be an adhesive portion of the main body portion 20 , or may be an adhesion means such as an adhesive provided on the tape member 60 , a hook member, or the like. In addition, the fixing portion 62 of the band member 60 may be configured to be able to be latched with respect to the main body portion 20 . The structure in which the fixing portion 62 is clamped to the main body portion 20 may be an adhesive portion of the main body portion 20 , or may be an adhesion means such as an adhesive provided on the tape member 60 or a hook member.

The non-fixed portion 64 of the tape member 60 of the present embodiment is stuck to the main body portion 20 via the main body adhesive portion 70 when being discarded. In the structure in which the strip member 60 is clamped to the body portion 20 by the adhesive portion of the body portion 20 , the non-fixing portion 64 may not be provided with an engagement means such as an adhesive.

As shown in FIG. 2 , the band member 60 may be arranged further inward than the outer edge 20E of the main body portion 20 in a state (natural state) that is not extended. The tape member 60 can also be covered by the main body portion 20 when viewed from the skin-opposing surface side. As shown in FIG. 4 , in the extended state (extended state), the band member 60 may extend outward from the outer edge 20E of the main body portion 20 . After use of the absorbent article 10, the user rolls up the body portion 20 in the front-rear direction L, and then extends the belt sheet member 60 to the outside of the outer edge 20E of the main body portion 20, and the belt sheet member 60 is engaged with the main body portion 20 (refer to FIG. 4 ).

According to such a configuration, during use of the absorbent article 10, since the belt sheet member 60 is arranged on the inner side of the outer edge 20E of the main body 20 on the non-skin facing surface side of the back sheet 22, menstrual blood does not adhere. such bodily fluids. After use of the absorbent article 10, the user can maintain the state in which the absorbent article 10 has been rolled up by engaging the tape member 60 extending outward to the main body adhesive portion 70 or the like. In this case, since bodily fluids such as menstrual blood do not adhere to the belt member 60, it is possible to prevent the reduction of the bonding force between the belt member 60 and the main body adhesive portion 70 or the reduction of the bonding force of the belt member engaging means. . Furthermore, during use of the absorbent article 10, since the belt sheet member 60 is provided on the non-skin facing surface side of the back sheet 22 and does not extend outward from the outer edge 20E of the main body 20, the belt sheet member 60 Does not directly contact the wearer's skin. Therefore, it is possible to reduce a sense of discomfort and discomfort during use.

In addition, in another form, the belt piece member 60 may be extended further outward than the outer edge 20E of the main body part 20 in the state (natural state) which is not extended. The belt sheet member 60 may be in a visually recognizable state when viewed from the skin-opposing surface side.

It is preferable that the belt piece member 60 is provided more rearward than the center in the front-rear direction L of the main body portion 20 . When a user generally lumps the absorbent article 10, the lump starts from the front end edge E1 or the rear end edge E2 of the absorbent article 10 toward the front-rear direction L. Among them, about 80% of users start to roll up from the front end edge E1 of the absorbent article 10 . Therefore, it is preferable that the band member 60 is provided in a region located on the rear side with respect to the center 20CL in the front-rear direction L of the main body portion 20 . At least a part of the belt sheet member 60 may straddle the rear end edge of the absorbent core 23, or may be arranged on the rear side of the rear end edge of the absorbent core.

Moreover, it is more preferable that the belt piece member 60 is provided in the rear side rather than the 2nd fold line F2 which is the rearmost side among the 1st fold line F1 - the 3rd fold line F3. About 80% of users roll up the absorbent article 10 after use from the front side. By arranging the tape member 60 on the rear side of the second fold line F2, many users start rolling from the front end edge E1 of the absorbent article 10, and the tape member 60 can be caught and rolled up. part.

An example of the specific structure of the absorbent article of this embodiment is shown. The surface sheet may be composed of an air non-woven fabric (PE/PET) with a basis weight of 30 g/m ² . A second sheet can be positioned between the topsheet and the absorbent core. The second sheet can be made of the same material as the surface sheet. The surface sheet is not arranged on the outer side in the width direction of the main body, but the side sheet may be arranged. As for the side sheets, it can be composed of SMS non-woven fabric (PP) with a basis weight of 13 g/m ² . The absorbent material of the absorbent core may be composed of coniferous kraft pulp and superabsorbent polymer. The ratio of the weight of the superabsorbent polymer to the weight of the absorbent material as a whole may be 10%. The basis weight of the absorbent core in the region comprising the excretory opposing domains may be constructed to be higher than the basis weight of the surrounding absorbent core. The basis weight of the absorbent core including the region of the excretion opening opposing domain S1 may be 950 g/m ² , and the basis weight of the surrounding absorbent core may be 300 g/m ² . The inner sheet may be composed of a polyethylene film (air impermeable type) having a basis weight of 23.5 g/m ² . The absorbent article may be formed with a pressing portion that presses the surface sheet and the absorbent core in the thickness direction. The main body adhesive part can be composed of a rubber-based hot-melt adhesive. The basis weight of the body adhesive may be 27 g/m ² . The main body adhesive part can be separated into 6 strips in the width direction. The length in the width direction of each main body adhesive portion may be 5 mm, and the length in the front-rear direction of each main body adhesive portion may be 320 mm. The length in the front-rear direction of the absorbent article may be 420 mm, and the length in the width direction of the absorbent article may be 200 mm. The strip member for post-treatment may be composed of a polyethylene film having a basis weight of 35 g/m ² . The length of the belt piece member in the longitudinal direction may be 45 mm, and the length of the belt piece member in the short side direction may be 25 mm. The strip member can be fixed to the main body by a rubber-based hot-melt adhesive having a basis weight of 100 g/m ² . The adhesive can be applied in the range of 21 mm in width and 5 mm in length. Printing may be applied to the inner sheet side surface of the belt sheet member. For printing, pink urethane inks can be used. In addition, the elongated belt member can be composed of a polypropylene layer with a basis weight of 10 g/m ² , a styrene-based rubber layer with a basis weight of 10 g/m ² , and a polypropylene layer with a basis weight of 10 g/m ² composed of accumulations.

Next, the bending base point part 80 of the absorbent article comprised in this way is demonstrated. The bending base point portion 80 serves as a base point when the main body portion 20 is bent in the front-rear direction L. As shown in FIG. The bending base portion 80 allows the body portion 20 to be easily bent due to a difference in rigidity, a difference in thickness, and a difference in basis weight.

The bend base section 80 may include the press section 26 . In more detail, the front end edge and the rear end edge of the press section 26 constitute the bending base point 80 . In addition, in the structure in which the plurality of press sections are shifted in the front-rear direction, the front end edge and the rear end edge of each press section constitute the bending base point 80 . The pressing portion constituting the bending base portion 80 is a portion for pressing the absorbent core, and does not include a portion for compressing only the top sheet. The press section 26 has higher rigidity and thinner thickness than a region in which the press section 26 is not formed. The pressing portion 26 constitutes the bending base portion 80 , so that the body portion 20 can be easily compacted due to the difference in thickness and rigidity. Suitably, as shown in FIG. 3, the press part 26 may be recessed from the skin opposing surface side T1 toward the non-skin opposing surface side T2. Generally, a user lumps the absorbent article 10 with the skin-opposing surface side T1 on which the excrement adhered as the inside when throwing it away. Since the pressing part 26 is recessed from the skin-opposing surface side T1 toward the non-skin-opposing surface side T2, it is easy to deform the skin-opposing surface side T1 close to the skin-opposing surface side T1, and the skin-opposing surface side T1 is formed to be easily absorbed Grouping of sexual objects.

The bending base point portion 80 may include a basis weight change portion. The basis weight change portion is a portion in which the basis weight of the absorbent material of the absorbent core 23 is different with respect to adjacent regions in the front-back direction L. Specifically, the front end edge and the rear end edge of the absorbent core 23 constitute the basis weight change portion. The front end edge and the rear end edge of the high basis weight portion also constitute the basis weight changing portion. The low basis weight portion differs in length in the front-rear direction. When the length in the front-rear direction of the low basis weight portion is less than 20 mm, the center in the front-rear direction of the low basis weight portion constitutes the basis weight changing 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 changing portion. Moreover, when a plurality of low-basis-weight parts are provided apart from each other in the front-rear direction, and when the plurality of low-basis-weight parts are connected, each of the low-basis-weight parts separated in the front-rear direction constitutes a basis weight changing part. The basis weight change portion configured in this way is different from the basis weight of the absorbent material in the region adjacent to the front-rear direction, and the thickness and rigidity of the absorbent core 23 are different. By constituting the bending base portion by the basis weight change portion, the absorbent article can be easily compacted due to the difference in thickness and the difference in rigidity.

The bending base portion 80 may include the low basis weight portion 25 provided in the absorbent core 23 as a basis weight change portion. The low basis weight portion 25 has higher rigidity and thinner thickness than the region where the low basis weight portion 25 is not formed. The low basis weight portion 25 constitutes the bending base point portion 80, and the absorbent article 10 can be easily rolled up due to the difference in thickness and rigidity. It is desirable that the low basis weight portion 25 serving as the basis weight changing portion may be provided along the broadside direction. The length L251 in the front-rear direction of the skin-opposing surface of the low basis weight portion 25 may be lower than the length L251 in the front-rear direction L of the non-skin-opposing surface of the basic weight portion 25 when viewed in a cross-section along the front-rear direction L shown in FIG. 3 . L252 is longer. Since the length L251 in the front-rear direction of the skin-opposing surface of the low basis weight portion 25 is longer than the length L252 in the front-rear direction of the non-skin-opposing surface of the low basis weight portion 25, it is easy to deform the skin-opposing surface side in close proximity. , and the absorbent article 10 can be easily lumped with the skin-opposing surface side as the inner side.

The folding base part 80 may include folds F1 , F2 and F3 which can fold the skin-opposing surfaces of the absorbent article 10 in a face-to-face manner. In the structure in which the folds have a constant length in the front-rear direction L, the front and rear edges of the folds F1 , F2 , and F3 constitute the bending base portion 80 . The skin-opposing surface side is easily deformed by the foldability of the folds F1, F2, and F3, so that the absorbent article 10 can be easily lumped with the skin-opposing surface side as the inner side. That is, the bending base point portion 80 may be constituted by at least one of the pressing portion 26 , the low basis weight portion 25 and the crease. Thus, by providing the bending base part 80, a user can easily roll up the absorbent article 10 in the front-rear direction, and it is easy to discard it in a lumped state.

A plurality of bending base point portions 80 are provided in each of the first region R1 and the second region R2. That is, a plurality of bending base point portions 80 are provided in the first region R1, and a plurality of the bending base point portions 80 are provided in the second region R2. Since a plurality of bending base points 80 are provided in each of the first region R1 and the second region R2, the entire absorbent article can be easily rolled up in the front-rear direction. The interval may be the distance in the front-rear direction between the bending base point portions adjacent to each other in the front-rear direction. In addition, in the structure in which the bending base points 80 are provided at intervals in the front-rear direction, each of them functions as the bending base parts 80 . However, when the distance between the bending base point portions 80 in the front-rear direction is 5 mm or less, since it functions as an integrated deformation base point, the plurality of bending base point portions 80 provided at intervals of 5 mm or less are all constituted by one. Bend the base part.

Specifically, the bending base point portion 80 of the second region R2 of the present embodiment is provided in the next order at intervals in the front-rear direction from the front side to the rear side. The bending base point portion 80 of the second region includes the front end edge of the absorbent core, the press portion 26 extending in the widthwise direction, a pair of dot-shaped press portions 26 spaced apart in the widthwise direction, and the The press section 26 in the center of the width direction, the first fold line F1, the low basis weight section 25, the low basis weight section 25, and the third fold line F3. The bending base point part 80 of the 1st area|region R1 of this embodiment is provided in the following order at intervals in the front-back direction from the front side toward the rear side. The bending base point portion 80 of the first region R1 includes a third crease F3, a press portion 26 extending in the front-rear direction L, a press portion 26 extending in the width direction, a second crease F2, and a press portion 26 extending in the width direction. The pressing portion 26 extending above and the rear end edge of the absorbent core.

The average interval of the bending base point portions 80 of the second region R2 is shorter than the average interval of the bending base point portions 80 of the first region R1. The interval is the interval between the bending base point portions 80 adjacent to each other in the front-rear direction L in each region. This interval also includes the distance between the outer edge of the absorbent article and the bending base 80 located most outward in the front-rear direction. The average interval is, for example, the interval D1 between the two bending base point portions 80 in a configuration in which two bending base point portions 80 are provided in the first region R1 . Moreover, the structure in which three of the first bending base point part, the second bending base point part and the third bending base point part are provided in the first region R1 is the interval between the first bending base point part and the second bending base point part , and the average value of the distance between the second bending base point portion and the third bending base point portion. In addition, the interval is the distance in the front-rear direction between the first bending base point portion and the second bending base point portion, for example, the front-rear direction L of the rear end edge of the first bending base point portion and the front end edge of the second bending base point portion the distance. FIG. 1 shows the interval D1 between the bending base point portions 80 in the first region R1 and the interval D2 between the bending base point portions 80 in the second region R2. In addition, when the plurality of bending base point portions 80 as a whole constitute one bending base point portion, the interval between the bending base point portions provided at intervals of 5 mm or less does not include the interval between the bending base point portions 80 .

In addition, in the structure in which a plurality of bending base point portions of the same shape are provided on the same line along the widthwise direction W, only one of the bending base point portions on the same line is selected to measure the distance in the front-rear direction. Specifically, as shown in FIG. 1 , in the second region R2, dot-shaped press sections 26 spaced apart in the width direction W are provided. The dot-shaped press section 26 includes a first dot-shaped press section 261 and a second dot-shaped press section 262 provided on the same line FL1 along the widthwise direction W. A third dot-shaped press section 263 is provided apart from the first dot-shaped press section 261 and the second dot-shaped press section 262 in the front-rear direction L. When calculating the average interval between the bending base point portions 80 in the second region R2, the interval D2 between the first point-like press portion 261 and the third point-like press portion 263 is calculated, and the second point-like press portion 262 and the third point-like press portion 262 may not be included. The interval D2 of the press section 263. Since there is no bending base point in the front-rear direction L, the first point-shaped press section 261 and the second point-shaped press section 262 function as a base point for bending the main body 20 in the front-rear direction L in cooperation.

The user rolls up the absorbent article 10 from the second region R2 side at the time of disposal, and the absorbent article 10 in the rolled up state is fixed by the belt sheet member 60 . At this time, since the average interval of the bending base point portions 80 of the second region R2 located on the inner side is short in the state after being rolled up, it can be rolled up tightly. In addition, since the first region R1 located on the outer side is also provided with a plurality of bending base points 80 in the state of being agglomerated, both the first region R1 and the second region R2 can be easily agglomerated, and the agglomeration can be easily maintained. state after transformation. Therefore, the sheet-attaching member 60 can be disposed of cleanly while maintaining the absorbent article 10 in a tightly spheroidized state.

The number of the bending base point portions 80 in the second region R2 may be greater than the number of the bending base point portions 80 in the first region R1. Since the number of bending bases of the second region R2 located on the inner side is large in the state after the agglomeration, a large number of deformation bases are formed inside the state after the agglomeration, and it is easier to form a compact shape. The number of the bending base point portions 80 is calculated by adding the total number of the bending base point portions 80 . For example, in a structure in which a plurality of bending base points of the same shape are provided on the same line along the widthwise direction W, not only one bending base point part on the same line is selected, but all the bending base points are added. part to calculate the number of bending base points. When an absorbent article is lumped, even if it tries to roll up in the front-back direction, it may be rolled up diagonally with respect to the front-back direction. In such a case, the first point-shaped press section 261 and the second point-shaped press section 262 function as different bending base points.

The bending base portion 80 may extend along the broadside direction W. As shown in FIG. The structures extending along the widthwise direction W include not only structures parallel to the widthwise direction W, but also structures inclined with respect to the widthwise direction W by less than 45 degrees. The deformation base point when the absorbent article 10 is swollen extends along the widthwise direction W, and the entire widthwise direction of the absorbent article 10 can be easily swelled in the front-rear direction.

The shape of the bending base portion is not limited, and may be a point shape, a belt shape, an arc shape, or a polygonal shape. The bending base part 80 may have a first bending base part 81 and a second bending base part 82 . The length W81 in the width direction W of the first bending base point portion 81 is longer than the length L81 in the front-rear direction L of the first bending base point portion 81 . The length L82 in the front-rear direction L of the second bending base point portion 82 is longer than the length W82 in the width direction W of the second bending base point portion 82 . The main body portion 20 is easily bent in the front-rear direction L based on the first bending base portion 81 , and is also easily bent in the widthwise direction W based on the second bending base portion 82 . The number of the 1st bending base point part 81 in the whole absorbent article may be more than the number of the 2nd bending base point part 82. When the absorbent article is lumped, it is easier to lump in the front-rear direction than in the widthwise direction. Therefore, it becomes easy to compactly compact the absorbent article in the front-rear direction, and it becomes easier to maintain the compacted state. Suitably, in the second region R2, the number of the first bending base point portions 81 may be larger than the number of the second bending base point portions 82, and in the first region R1, the number of the first bending base point portions 81 may be larger than that of the second bending base point portion 82. The number of the second bending base point portions 82 is larger.

Moreover, the absorbent article 10 may have a structure in which it is easy to maintain the state of being lumped in the front-rear direction. As shown in FIG. 2 , the maximum length WR1 in the width direction W of the first region R1 may be longer than the maximum length WR2 in the width direction W of the second region R2. Since the maximum length WR1 in the width direction of the first region located on the outer side is long in the state after the agglomeration, the second region R2 located on the inner side in the state after the agglomeration can be covered by the first region R1 located on the outer side. , and it becomes easier to maintain the state after grouping.

Three or more bending base point portions 80 are provided in the range from the outer edge of the main body portion 20 in the front-rear direction to 1/3 of the length of the main body portion 20 in the front-rear direction in the first region R1 . The outer edge in the front-rear direction of the main body portion 20 in the first region R1 is the rear end edge of the main body portion 20 in this embodiment. FIG. 1 shows a range R3 from the outer edge of the main body portion 20 in the front-rear direction to 1/3 of the length of the main body portion 20 in the front-rear direction. The perimeter in the state where the main body portion is rounded in the front-rear direction is generally formed to be about 1/3 of the length in the front-rear direction of the main body portion. With respect to 1/3 of the length of the main body part in the front-rear direction, it is the part which becomes the surface located on the outer side in the state after agglomeration. By providing three or more bending base points in this part, it becomes easier to maintain the state after the agglomeration.

At this time, the rear end edge of the third fold line, the front end edge of the fifth press section 26E, and the rear end edge of the fourth press section have a distance between each other in the front-rear direction of 5 mm or less, and thus constitute one bending base point 80 . . In addition, in FIG. 5, the part shown by the heart shape is a part which compresses only a surface sheet, and does not constitute a bending base part.

Next, the absorbent article 10B of the second embodiment will be described. 6 : is a top view of the absorbent article 10B of 1st Embodiment seen from the skin opposing surface side. FIG. 7 is a cross-sectional view taken along line B-B shown in FIG. 6 . The plan view of the absorbent article viewed from the non-skin-opposing surface side and the perspective view of the absorbent article in a state rolled up in the front-rear direction are common to FIGS. 2 and 4 shown in the first embodiment.

Next, the bending base point part 80 of the absorbent article comprised in this way is demonstrated. The bending base point portion 80 serves as a base point when the main body portion 20 is bent in the front-rear direction L. As shown in FIG. The bending base portion 80 allows the body portion 20 to be easily bent due to a difference in rigidity, a difference in thickness, and a difference in basis weight.

The bending base point portion 80 of the first region includes the rear end edge of the absorbent core, the press portion 26 extending in the widthwise direction, a pair of dot-shaped press portions 26 spaced apart in the widthwise direction, and the main body portion. The press part 26, the 1st fold line F1, the low basis weight part 25, the low basis weight part 25, and the 3rd fold line F3 in the center of the width direction. The bending base point part 80 of the 2nd area|region R2 of this embodiment is provided in the following order at intervals in the front-back direction from the rear side toward the front side. The bending base point portion 80 of the second region R2 includes a third crease F3, a press portion 26 extending in the front-rear direction L, a press portion 26 extending in the width direction, a second crease F2, and a press portion 26 extending in the width direction. The pressing portion 26 extending upward and the front end edge of the absorbent core.

The average interval of the bending base point portions 80 of the first region R1 is shorter than the average interval of the bending base point portions 80 of the second region R2. The interval is the interval between the bending base point portions 80 adjacent to each other in the front-rear direction L in each region. This interval also includes the distance between the outer edge of the absorbent article and the bending base 80 located most outward in the front-rear direction. The average interval is, for example, the interval D1 between the two bending base point portions 80 in a configuration in which two bending base point portions 80 are provided in the first region R1 . In addition, the structure in which three of the first bending base point portion, the second bending base point portion, and the third bending base point portion are provided in the first region R1 is the interval between the first bending base point portion and the second bending base point portion. , and the average value of the distance between the second bending base point portion and the third bending base point portion. In addition, the interval is the distance in the front-rear direction between the first bending base point portion and the second bending base point portion, for example, the front-rear direction L of the rear end edge of the first bending base point portion and the front end edge of the second bending base point portion the distance. FIG. 6 shows the interval D1 between the bending base point portions 80 in the first region R1 and the interval D2 between the bending base point portions 80 in the second region R2. In addition, when the plurality of bending base point portions 80 as a whole constitute one bending base point portion, the interval between the bending base point portions provided at intervals of 5 mm or less does not include the interval between the bending base point portions 80 .

In addition, in the structure in which a plurality of bending base point portions of the same shape are provided on the same line along the widthwise direction W, only one of the bending base point portions on the same line is selected to measure the interval. Specifically, as shown in FIG. 6 , in the second region R2, dot-shaped press sections 26 spaced apart in the width direction W are provided. The dot-shaped press section 26 includes a first dot-shaped press section 261 and a second dot-shaped press section 262 provided on the same line FL1 along the widthwise direction W. A third dot-shaped press section 263 is provided apart from the first dot-shaped press section 261 and the second dot-shaped press section 262 in the front-rear direction L. When calculating the average distance between the bending base points 80 in the second region R2, the distance D1 between the first point press part 261 and the third point press part 263 can be calculated, and the second point press part 262 and the third point press part 262 are not included. The interval D1 of the shaped press section 263. Since there is no bending base point in the front-rear direction L, the first point-shaped press section 261 and the second point-shaped press section 262 function as a base point for bending the main body 20 in the front-rear direction L in cooperation.

The user lumps the absorbent article from the second region side at the time of disposal, and the absorbent article in the lumped state is fixed by the belt sheet member. At this time, the first region R1 located on the outer side after being agglomerated is rolled up along the portion located on the inner side (the second region R2 ) in the state after the agglomeration. Since the average interval of the bending base point portions 80 of the first region R1 is short, the first region R1 located on the outer side in the agglomerated state can be bent at short intervals. Therefore, in a state where the second region R2 is agglomerated, even if unevenness is formed toward the outside, the first region R1 is easily agglomerated into a circular shape. In addition, since a plurality of bending base point portions 80 are also provided in the second region R2 located on the inner side in the state of being rounded, both the first region R1 and the second region R2 can be easily formed by the bending base point portions 80. It is easy to maintain the state after the agglomeration. Therefore, the absorbent article can be disposed of cleanly by the belt sheet member for post-processing, while maintaining the state after the agglomeration.

The number of the bending base point portions 80 in the first region R1 may be greater than the number of the bending base point portions 80 in the second region R2. Since the number of bending base points in the second region R2 located on the outside is large in the state after the agglomeration, many deformation base points are formed on the outside of the state after the agglomeration, and it is easier to maintain a compact shape. state. The number of the bending base point portions 80 is calculated by adding the total number of the bending base point portions 80 . For example, in a structure in which a plurality of bending base points of the same shape are provided on the same line along the widthwise direction W, not only one bending base point part on the same line is selected, but all the bending base points are added. part to calculate the number of bending base points. When an absorbent article is lumped, even if it tries to roll up in the front-back direction, it may be rolled up diagonally with respect to the front-back direction. In such a case, the first point-shaped press section 261 and the second point-shaped press section 262 function as different bending base points.
