(1) Outline of Embodiment At least the following matters will become clear by the description of the present specification and the attached drawings.

The user rounds the absorbent article from the second area side at the time of disposal, and fixes the rolled-up absorbent article by the tape member. At this time, since the average distance between the bending origins of the second area located inside in a rounded state is short, it is possible to make the rounding compact. In addition, since a plurality of bending base points are provided also in the first area located outside in the rounded state, both the first area and the second area can be easily rounded, and the rounded state is maintained. easy. Thus, the absorbent article can be kept compact and can be disposed of cleanly by the post-treatment tape member.

According to a preferred aspect, the number of the bending base points of the second area is larger than the number of the bending base points of the first area.

According to the absorbent article according to one aspect, since the number of bending base points is large in the second region located inside in the rolled state, many deformation base points are formed inside the rolled state, and the rounding due to compactness easy.

The user rounds the absorbent article from the second area side at the time of disposal, and fixes the rolled-up absorbent article by the tape member. At this time, the first area located outside when rolled is wound along the part located inside in a rolled state. Since the average distance between the bending base points of the first region is short, the first region located outside in the rounded state can be bent at a short distance. Therefore, even if the unevenness is formed on the outer surface in a state in which the second region is rounded, it is easy to round the first region into a circular shape. In addition, since a plurality of bending origins are provided also in the second area located inside in the rolled state, both the first area and the second area can be compactly rounded by the bending origin, and the rounding is performed. It is easy to maintain Thus, the absorbent article can be maintained in a rolled state and can be disposed of cleanly by the post-treatment tape member.

According to a preferred aspect, the number of bending base points of the first region is larger than the number of bending base points of the second region.

According to the absorbent article according to the other aspect, since the number of bending origins is large in the first area located outside in the rolled state, many deformation base points are formed outside the rolled state, and more rounding is performed. It is easy to maintain

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

The user usually starts to roll back and forth from the front end edge or the rear end edge of the absorbent article when the absorbent article is rolled. Among them, about 80% of users start rounding from the front end edge of the absorbent article. Therefore, it is preferable that the tape member be provided in a region located on the rear side with respect to the center in the front-rear direction.

According to a preferable 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.

Since the maximum length in the width direction of the first area located outside in the rounded state is long, the second area located inside in the rounded state can be covered by the first area located outside, and the rounded state Is easier to maintain.

According to a preferred aspect, the bending base point portion includes a squeezed portion obtained by squeezing at least the absorbent core in the thickness direction.

The squeezed portion is higher in rigidity and thinner than the region where the squeezed portion is not formed. Since the said pressing part comprises a bending origin point part, it becomes easy to round an absorbent article compactly by thickness difference and rigidity difference.

According to a preferable aspect, the pressing portion is recessed from the skin facing surface side toward the non-skin facing surface side.

In general, the user rolls the absorbent article with the side facing the skin on which the excrement adheres at the time of disposal. Since the pressing portion is recessed from the skin facing surface side toward the non-skin facing surface side, the skin facing surface side is easily deformed so as to be close, and the absorbent article is easily rounded with the skin facing surface side inside.

According to a preferred aspect, the bending base point portion includes a basis weight changing portion in which the basis weight of the absorbent material of the absorbent core is different with respect to the adjacent region in the front-rear direction.

The weight change portion has a difference in weight of the absorbent material from the region adjacent in the front-rear direction, and the thickness and rigidity of the absorption core are different. When the fabric weight changing portion constitutes the bending base point portion, the absorbent article can be easily rounded in a compact manner due to the thickness difference and the rigidity difference.

According to a preferred aspect, the fabric weight changing portion is a low fabric weight portion having a low fabric weight with respect to the region adjacent in the front-rear direction,
The low basis weight portion is provided along the width direction,
The length in the front-rear direction of the skin-facing surface of the low basis weight portion is longer than the length in the front-rear direction of the non-skin-facing surface of the low basis weight portion in cross-sectional view along the front-rear direction.

In general, the user rolls the absorbent article with the side facing the skin on which the excrement adheres at the time of disposal. Since the length in the front-rear direction of the skin facing surface of the low basis weight portion is longer than the length in the front-back direction of the non-skin facing surface side of the low basis weight portion, the skin facing surface side is easily deformed so that the skin facing surface side is inside. Thus, the absorbent article can be easily rolled.

According to a preferred aspect, the folding base point portion includes a fold that is folded so that the skin-facing surface of the absorbent article faces each other.

It is easy to be deformed so that the skin facing surface side approaches by the crease of the fold, and it becomes easy to round the absorbent article with the skin facing surface side inside.

According to a preferred aspect, the bending base point extends along the width direction.

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

According to a preferred 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 the length in the front-rear direction is longer than the length in the width direction And a long second bending base point, and the number of the first bending base points is larger than the number of the second bending base points.

Since the number of first bending base points is large in the number of second bending base points, when the absorbent article is rolled, it becomes easier to roll in the front-rear direction than in the width direction. Therefore, it becomes easier to round the absorbent article more compactly in the front-rear direction, and it is easier to maintain the rolled state.

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

Generally, the circumferential length of the main body portion in the front-rear direction is about 1/3 of the length of the main body portion in the front-rear direction. One third of the length of the main body in the front-rear direction is a portion located on the outer surface in a rounded state. By providing three or more bending base points in the portion, it is easier to maintain the rolled state.

The user usually starts to roll in the front-rear direction L from the front end edge E1 or the rear end edge E2 of the absorbent article 10 when the absorbent article 10 is rolled up. Among them, about 80% of users start rounding from the front end edge E1 of the absorbent article 10. Therefore, it is preferable that the tape member 60 be provided in a region located on the rear side with respect to the center 20CL of the main body portion 20 in the front-rear direction L. At least a portion of the tape member 60 may be disposed across the rear end edge of the absorbent core 23 or on the rear side of the rear end edge of the absorbent core.

More preferably, the tape member 60 is provided on the rear side of the rearmost second fold line F2 among the first fold line F1 to the third fold line F3. About 80% of users start winding the used absorbent article 10 from the front side. By providing the tape member 60 behind the second fold line F 2, many users can start rounding from the front end edge E 1 of the absorbent article 10 and fasten the wound end portion with the tape member 60.

An example of a concrete structure of the absorbent article of this Embodiment is shown. The top sheet may be constituted by an air through non-woven fabric (PE / PET) having a basis weight of 30 g / m ² . A second sheet may be provided between the top sheet and the absorbent core. The second sheet may be made of the same material as the top sheet. A surface sheet may not be arrange | positioned on the outer side of the width direction of a main-body part, but a side sheet may be arrange | positioned. The side sheet may be constituted by an SMS nonwoven fabric (PP) having a basis weight of 13 g / m ² . The absorbent material of the absorbent core may be composed of softwood kraft pulp and a superabsorbent polymer. The ratio of the weight of superabsorbent polymer to the weight of the whole absorbent material may be 10%. The basis weight of the absorbent core in the region including the outlet facing region may be higher than the basis weight of the surrounding absorbent core. The basis weight of the absorbent core in the area including the excretion port facing area S1 may be 950 g / m ² , and the basis weight of the surrounding absorbent core may be 300 g / m ² . The back sheet may be constituted by a polyethylene film (non-air-permeable type) with a basis weight of 23.5 g / m ² . The absorbent article may have a pressing portion in which the top sheet and the absorbent core are pressed in the thickness direction. The main body adhesive portion may be made of a rubber-based hot melt adhesive. The basis weight of the adhesive part of the main body may be 27 g / m ² . There may be six main body adhesive portions spaced 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 of the absorbent article in the front-rear direction may be 420 mm, and the length of the absorbent article in the width direction may be 200 mm. The tape member for post-treatment may be composed of a polyethylene film having a basis weight of 35 g / m ² . The longitudinal length of the tape member may be 45 mm, and the lateral length of the tape member may be 25 mm. The tape member may be fixed to the main body by a rubber-based hot melt adhesive with a weight of 100 g / m ² . The adhesive may be applied in the range of 21 mm wide and 5 mm long. Printing may be applied to the surface on the back sheet side of the tape member. The printing may use a pink urethane ink. As the tape member extending polypropylene layer having a basis weight of 10 g / m ^2, a styrene-based rubber layer having a basis weight of 10 g / m ^2, and may be constituted by a stack of basis weight polypropylene layer of 10 g / m ^2.

Subsequently, the bending origin point part 80 of the absorbent article comprised in this way is demonstrated. The bending base point portion 80 is a base point when the main body portion 20 is bent in the front-rear direction L. The bending base point portion 80 makes the main body portion 20 easy to bend due to a difference in rigidity, a difference in thickness, a difference in fabric weight, and the like.

The bending base point portion 80 may include a pressing portion 26. More specifically, the front end edge and the rear end edge of the pressing portion 26 constitute a bending base point 80. Further, in the configuration in which the plurality of pressing portions are arranged to be shifted in the front-rear direction, the front end edge and the rear end edge of each pressing portion constitute the bending base point portion 80. The pressing part which comprises the bending origin point part 80 is a part which compressed the absorption core, and does not contain the part which compressed only a surface sheet. The squeezed portion 26 is higher in rigidity and thinner than the region where the squeezed portion 26 is not formed. By the compression part 26 comprising the bending base point part 80, it becomes easy to round the main-body part 20 compactly by thickness difference and rigidity difference. Suitably, as shown in FIG. 3, the pressing part 26 may be dented toward the non-skin opposing surface side T2 from the skin opposing surface side T1. Generally, the user rounds the absorbent article 10 with the skin-facing surface side T1 on which the excrement adheres at the time of disposal placed inside. Since the pressing portion 26 is recessed from the skin facing surface T1 toward the non-skin facing surface T2, the skin facing surface T1 tends to be deformed so that the skin facing surface T1 is inward with the absorbent article It becomes easy to round.

The bending base point portion 80 may include a basis weight changing portion. The basis weight changing portion is a portion where the basis weight of the absorbent material of the absorbent core 23 is different from that of the adjacent region in the front-rear direction L. Specifically, the front end edge and the rear end edge of the absorbent core 23 constitute a fabric weight changing portion. The front end edge and the rear end edge of the high basis weight also constitute a basis weight change part. The low basis weight varies depending on the 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 a 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 a basis weight variation portion. 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, each of the low basis weight portions separated in the front-rear direction constitutes a basis weight change portion. The area weight change part comprised in this way differs in the area weight of the area | region adjacent to the front-back direction from the area weight of an absorbent material, and the thickness and rigidity of the absorption core 23 differ. When the fabric weight changing portion constitutes the bending base point portion, the absorbent article can be easily rounded in a compact manner due to the thickness difference and the rigidity difference.

The bending base point portion 80 may include a low basis weight portion 25 provided in the absorbent core 23 as a basis weight changing portion. The low basis weight 25 is higher in rigidity and thinner than the region in which the low basis weight 25 is not formed. The low basis weight portion 25 constituting the bending base point portion 80 makes it easy to round the absorbent article 10 due to the thickness difference and the rigidity difference. Preferably, the low basis weight 25 as the basis weight changing part may be provided along the width direction. In a cross-sectional view along the longitudinal direction L shown in FIG. 3, the length L251 of the skin opposing surface of the low basis weight portion 25 is greater than the length L252 of the non-skin opposing surface of the low basis weight portion 25. May be long. Since the length L251 in the front-rear direction of the skin facing surface of the low basis weight portion 25 is longer than the length L252 in the front-back direction of the non-skin facing surface of the low basis weight portion 25, the skin facing surface side tends to be deformed closer It becomes easy to roll up the absorbent article 10 with the face side inside.

The folding base point portion 80 may include folds F1, F2 and F3 that are folded so that the skin facing surfaces of the absorbent article 10 face each other. When the fold has a predetermined length in the front-rear direction L, the front end edge and the rear end edge of the folds F1, F2 and F3 constitute the bending base point 80. It is easy to be deformed so that the skin opposing surface side approaches by the folds of the folds F1, F2 and F3, and it becomes easy to round the absorbent article 10 with the skin opposing surface side inside. That is, the bending base point portion 80 may be configured by at least one of the pressing portion 26, the low basis weight portion 25 and the fold. By providing the bending base point portion 80 in this manner, the user can easily wind the absorbent article 10 in the front-rear direction and easily discard in the rolled state.

That is, the bending origin point part 80 is provided with two or more by 1st area | region R1, and is provided with two or more by 2nd area | region R2. Since the 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 rounded in the front-rear direction. The interval may be the distance between the bending base points adjacent in the front-rear direction. In addition, in the configuration in which the bending base point portions 80 are provided in a plurality at intervals in the front-rear direction, each functions as the bending base point portion 80. However, if the distance between the bending base points 80 in the front-rear direction is 5 mm or less, it functions as an integrated deformation base point, so that the entire plurality of bending base points 80 provided at intervals of 5 mm or less is one. Constitute the bending origin of the

Specifically, the bending base point portions 80 of the second region R2 of the present embodiment are provided in the following order at intervals in the front-rear direction from the front side toward the rear side. The bending origin point 80 of the second region is located at the front end edge of the absorbent core, the pressing portion 26 extending in the width direction, the pair of point-like pressing portions 26 spaced in the width direction, and the center of the main body in the width direction. And a first crease F1, a low basis weight 25, a low basis weight 25, and a third fold F3. The bending base points 80 of the first region R1 of the present embodiment are provided in the following order at intervals in the front-rear direction from the front to the rear. The bending base point 80 of the first region R1 has a third fold F3, a pressing portion 26 extending in the front-rear direction L, a pressing portion 26 extending in the width direction, a second fold F2, a pressing portion 26 extending in the width direction, and an absorbent core Includes the trailing edge.

The average distance between the bending base points 80 of the second region R2 is shorter than the average distance between the bending base points 80 of the first region R1. The interval is an interval between the bending base point portions 80 adjacent in the front-rear direction L in each region. The space also includes the distance between the outer edge of the absorbent article and the bending base point 80 located on the outermost side in the front-rear direction. The average distance is, for example, the distance D1 between the two bending base points 80 in the configuration in which two bending base points 80 are provided in the first region R1. In addition, in the configuration in which three of the first bending origin, the second bending origin, and the third bending origin are provided in the first region R1, the first bending origin and the second bending origin are provided. It is an average value of the space | interval of a bending origin point part, and the space | interval of a 2nd bending origin point part and a 3rd bending origin point part. The interval is the distance between the first bending base point and the second bending base point in the front-rear direction, and for example, the distance between the rear end edge of the first bending base point and the front edge of the second bending base point It is a distance in the front-rear direction L. FIG. 1 shows the distance D1 between the bending base point portions 80 in the first region R1 and the distance D2 between the bending base point portions 80 in the second region R2. When the entire plurality of bending base points 80 constitute one bending base point, the interval between bending base points provided at an interval of 5 mm or less is included in the interval between bending base points 80. Absent.

In the configuration in which a plurality of bending base points of the same shape are provided on the same line along the width direction W, only one of the bending base points on the same line is selected, and Measure the interval. Specifically, as shown in FIG. 1, point-like pressing portions 26 spaced in the width direction W are provided in the second region R2. The point-like pressing part 26 has a first point-like pressing part 261 and a second point-like pressing part 262 provided on the same line FL1 along the width direction W. A third point-like pressing portion 263 is provided apart from the first point-like pressing portion 261 and the second point-like pressing portion 262 in the front-rear direction L. When calculating the average interval of the bending origin point part 80 of 2nd area | region R2, the space | interval D2 of the 1st point-like pressing part 261 and the 3rd point-like pressing part 263 is included, and the 2nd point-like pressing part 262 and the 2nd The interval D2 of the three-point presser 263 may not be included. The first point-like pressing part 261 and the second point-like pressing part 262 cooperate to function as a base point for bending the main body part 20 in the front-rear direction L and not to constitute a bending base point shifted in the front-rear direction L .

At the time of disposal, the user rounds the absorbent article 10 from the second region R2 side and fixes the rolled-up absorbent article 10 with the tape member 60. At this time, since the average distance between the bending base portions 80 of the second region R2 located inside in the rolled state is short, the compact can be performed. In addition, since the plurality of bending base points 80 are provided also in the first region R1 located outside in the rounded state, both the first region R1 and the second region R2 can be easily rounded, and the rounded regions are rounded. It is easy to maintain the state. Therefore, the absorbent article 10 can be kept in a compactly rolled state and can be disposed of cleanly by the tape member 60.

The number of bending base points 80 of the second region R2 may be larger than the number of bending base points 80 of the first region R1. Since the number of bending origins of the second region R2 located inside in the rolled state is large, many deformation base points are formed inside the rolled state, and it is easy to round because of the compactness. The number of bending base points 80 is calculated by adding the number of all bending base points 80. For example, in a configuration in which a plurality of bending base points of the same shape are provided on the same line along the width direction W, only one bending base point on the same line is not selected, and all The number of bending base points is calculated by adding the bending base points. When the absorbent article is rolled, even if it is wound in the back and forth direction, it may be wound obliquely to the front and back direction. In such a case, the first point-like pressing portion 261 and the second point-like pressing portion 262 function as different bending base points.

The bending base point 80 may extend along the width direction W. The configuration extending along the width direction W includes not only a configuration parallel to the width direction W but also a configuration inclined at less than 45 degrees with respect to the width direction W. The deformation base point when rolling the absorbent article 10 extends along the width direction W, and the entire width direction of the absorbent article 10 can be easily rounded in the front-rear direction.

The shape of the bending base point portion is not limited, and may be point-like, band-like, arc-like, or polygonal. The bending base point portion 80 may have a first bending base point portion 81 and a second bending base point portion 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 of the second bending base point portion 82 in the front-rear direction L is longer than the length W82 of the width direction W of the second bending base point portion 82. The main body portion 20 easily bends in the front-rear direction L with the first bending base point portion 81 as a base point, and easily bends in the width direction W with the second bending base point portion 82 as a base point. The number of first bending base points 81 in the entire absorbent article may be larger than the number of second bending base points 82. When the absorbent article is rolled, it becomes easier to roll in the front-rear direction than in the width direction. Therefore, it becomes easier to round the absorbent article more compactly in the front-rear direction, and it is easier to maintain the rolled state. Preferably, in the second region R2, the number of first bending base portions 81 is larger than the number of second bending base portions 82, and in the first region R1, the number of first bending base portions 81 is The number may be larger than the number of second bending base points 82.

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 of the second region R2. Since the maximum length WR1 in the width direction of the first area located outside in the rounded state is long, the second area R2 located inside in the rounded state can be covered by the first area R1 located outside, It becomes easier to maintain the rolled state.

Three or more bending base points 80 may be provided in a range from the outer end edge of the main body 20 in the front-rear direction in the first region R1 to 1⁄3 of the length in the front-rear direction of the main body 20.
