DESCRIPTION OF EMBODIMENTS

[0010]

At least the following questions will become apparent from the description in this description and the accompanying drawings.

According to an aspect of the invention, the absorbent article includes a longitudinal direction, a width direction, and a thickness direction;

absorbent component; an upper sheet located on the side of the skin surface of the absorbent component, and a back sheet located on the side of the skin surface of the absorbent component;

wherein the first fold line and the second fold line for folding the absorbent article are formed along the longitudinal direction,

the top sheet has a bent portion, bent along the bending line, on both sides of the top sheet in the width direction,

the folding line is located outside in the width direction with respect to the outer side edge of the absorbent component,

the end of the bent portion is located inside in the width direction with respect to the outer side edge of the absorbent component, and

the first fold line and the second fold line are located outside in the width direction with respect to the folding line.

[0011]

In the state in which the absorbent article is folded along the first bend line and the second fold line extending in the longitudinal direction, the length in the width direction is less than its length in the width direction in the unfolded state in which the absorbent article is not folded along the first bend line and the second bend line so that it can be conveniently carried in a compact state. In addition, since the length of the top sheet in the width direction is greater than the length of the absorbent component in the width direction, the user can realize that the width of the top sheet into which the body fluid is absorbed is large, and can get a comfortable sensation of absorbency. Therefore, the user can get a comfortable sensation with respect to absorbency while providing ease of carrying in a compact state.

[0012]

The bending line of the bent portion is located outside in the width direction with respect to the outer lateral edge of the absorbent component, and the end of the bent portion is located inside in the width direction with respect to the outer side edge of the absorbent component. Therefore, at least the two-layer top sheet is located externally in the width direction with respect to the outer lateral edge of the absorbent component. You can realize that the width of the top sheet into which the fluid released by the body is absorbed is large, and you get a comfortable feeling in terms of absorbency. An area located externally in the width direction with respect to the outer side edge of the absorbent component is provided with an area thickened by a two-layer absorbent sheet, and the user has a feeling that the fluid released by the body is absorbed properly into the thickened area, and the user can get a comfortable sensation regarding absorbency.

[0013]

In addition, the first fold line and the second fold line are located outside in the width direction with respect to the folding line. A bend mark due to the first bend line and the second bend line does not form in the area thickened by the two-layer top sheet. Therefore, it will be difficult to lift the lateral edge of the upper sheet due to a trace of bending, and it is possible to suppress the closing of the side of the absorbent component with the upper sheet. The user can visually recognize the entire area, including the lateral part of the absorbent component, and get a comfortable sensation with respect to absorbency. In addition, a bend mark resulting from the first bend line and the second bend line does not form on the side of the absorbent component. Therefore, when the absorbent article is unfolded, the user can visually recognize the side portion of the absorbent component, recognize the actual length of the absorbent component in the width direction, and obtain a comfortable sensation with respect to the absorbency.

[0014]

In absorbent article

it is preferable that an area in which portions of the top sheet overlap each other in the thickness direction and portions of the top sheet are not attached to each other is provided between the folding line and the outer side edge of the absorbent component.

[0015]

According to the design of such an absorbent article, it is possible to make an area in which portions of the top sheet will be separated from each other, between the folding line and the outer side edge of the absorbent component. In this area, the bent portion of the top sheet tends to be convex, and the thickness of the top sheet in the area in which the bent portion is located is likely to be substantially the same as or greater than the thickness of the absorbent component. The thickness is essentially the same as the thickness of the absorbent component having absorbency, is stored towards the side that is outer in the direction of thickness, so that the user can realize that the absorbent zone is wide, and get a comfortable feeling with respect to absorbency.

[0016]

In absorbent article

preferably, the absorbent article comprises an area in which the bent portion of the top sheet is not attached to the back sheet.

[0017]

In an area in which the bent portion of the top sheet is not attached to the back sheet, the top sheet and the back sheet are likely to separate from each other in the thickness direction, and the bent portion of the top sheet is likely to be in a convex state. The thickness of the top sheet in the region in which the bent portion is located tends to be substantially the same as or greater than the thickness of the absorbent component. The thickness is essentially the same as the thickness of the absorbent component having absorbency, is maintained towards the side that is outer in the width direction, so that the user can realize that the absorbent zone is wide, and get a comfortable feeling with respect to absorbency.

[0018]

In absorbent article

it is preferable that only a part of the top sheet located on the side facing the skin of the surface, of the parts of the top sheet located between the bending line and the outer side edge of the absorbent component, was made with the indented part facing the skin of the surface.

[0019]

According to the design of the absorbent article by means of the indented portion of the surface facing the skin, the user can recognize that the absorption capacity of the body fluid is high and can get a comfortable sensation of absorbency. In addition, since the indented portion of the skin-facing surface is formed only on the portion of the upper sheet located on the side of the skin-facing surface, portions of the upper sheet overlapping each other in the thickness direction in the bent portion are not bonded by the indented portion of the skin-facing surface. Therefore, the thickening of the area in which the bent portion is located can be maintained, and the user can get a comfortable sensation with respect to absorbency.

[0020]

Absorbent article

includes an indented portion of the absorbent component formed on the absorbent component and the top sheet, and

preferably depth the indented portion of the surface facing the skin in the thickness direction was less than the depth of the indented portion of the absorbent component in the thickness direction.

[0021]

Since, in accordance with the design of the absorbent article, the depth of the indented part of the surface facing the skin in the thickness direction is less than the depth of the indented part of the absorbent component in the thickness direction, the thickening of the area in which the bent part is located can be maintained, and the user can get a comfortable sensation of absorbency.

[0022]

Absorbent article

includes a second sheet provided between the absorbent component and the top sheet,

it is preferable that the second sheet extends outward in the width direction beyond the outer lateral edge of the absorbent component.

[0023]

According to the design of the absorbent article, at least the two-layer top sheet and the second sheet are arranged externally in the width direction with respect to the outer side edge of the absorbent component. An area thickened by a three-layer sheet can be obtained externally in the width direction with respect to the outer lateral edge of the absorbent component. The user has the feeling that the fluid released by the body is appropriately absorbed into the thickened area, and the user can get a comfortable sensation regarding absorbency.

[0024]

In absorbent article

it is preferred that the second sheet has a folded portion folded along the folding line.

[0025]

According to the design of the absorbent article, an area in which at least a two-layer top sheet and at least two parts of the second sheet superimposed on one another, provided externally in the width direction with respect to the outer lateral edge of the absorbent component. An area thickened by a four-layer sheet may be provided externally in the width direction with respect to the outer side edge of the absorbent component. The user has the feeling that the fluid released by the body is appropriately absorbed into the thickened area, and the user can get a comfortable sensation with respect to absorbency.

[0026]

According to another aspect of the invention, the absorbent article includes: a longitudinal direction, a width direction and a thickness direction;

absorbent component;

a top sheet located on the side of the surface of the absorbent component facing the skin;

a back sheet located on the side of the surface of the absorbent component not facing the skin; and

a wing provided in the crotch area in the longitudinal direction,

wherein the first fold line and the second fold line for folding the absorbent product are formed along the longitudinal direction so that parts of the skin-facing surface of the absorbent product are facing each other,

the top sheet has a bent portion, bent along the bending line, on both sides in the width direction,

the first fold line and the second fold line are located in the crotch area inside in the width direction with respect to the bending line,

the absorbent article has a bonded portion in which the folded portion and the back sheet are bonded, and

the bonded portion is located in the crotch area inside in the width direction with respect to the folding line.

[0027]

A bend mark due to the first bend line and the second bend line extending in the longitudinal direction is formed on the bent portion of the top sheet. The first fold line and the second fold line are folding lines so that parts of the skin-facing surface of the absorbent article face each other, and in the unfolded state in which the absorbent article is unfolded, a bend mark resulting from the first fold line and the second fold line, becomes the trace of folding in the form of a depression facing the carrier. In the region between the bending line and the bonded part, the bent part and the back sheet are not attached to each other, and the bent part rises to the side of the carrier due to a bending mark caused by the first bending line and the second folding line. The bent portion rises, and as a result, side leakage of the fluid secreted by the body can be suppressed.

[0028]

Furthermore, when an absorbent article made with this configuration is attached to the undergarment in a state in which the center of the absorbent article is fastened in the width direction to the skin-facing surface of the undergarment, the wing is pulled to the side of the undergarment of the undergarment and the wing is attached to the non-skin surface of the underwear. If the wing is pulled toward the side of the underwear surface not facing the skin, the bent portion of the upper sheet is also pulled by the bonded portion. In this case, when the wing, which is not attached to the back sheet in the area between the bending line and the bonded part, is pulled towards the side not facing the skin, the wing does not stretch to the side not facing the skin along with the back sheet, whereby elevated state. Therefore, it is possible to maintain the elevated state of the bent portion of the top sheet and suppress the lateral leakage of fluid released by the body.

[0029]

In absorbent article

preferably, the bonded portion is located in the crotch area inside in the width direction with respect to the first fold line and the second fold line.

[0030]

In accordance with the design of the absorbent article in an area located externally in the width direction with respect to the first fold line and the second fold line, the top sheet is made to be lifted from the back sheet. You can save the raised state of the upper sheet at the first bend line and the second bend line as the places where the lift begins and suppress the lateral leakage of the fluid secreted by the body.

[0031]

In absorbent article

preferably, the first fold line and the second fold line are located inside in the width direction with respect to the outer side edge of the absorbent component.

[0032]

Since, according to the design of the absorbent article, the first fold line and the second fold line are formed on the absorbent component, the bending mark due to the first fold line and the second fold line is stronger and the bent portion of the top sheet tends to rise. In addition, the rigidity of the part in which the first bend line and the second bend line are formed is increased. The bent part of the upper sheet rises at the first bend line and the second bend line as the places where the deformation began. Since the stiffness of the deformation start point is increased during lifting, the raised state of the bent part of the upper sheet is easier to maintain, and side leakage of the fluid secreted by the body can be suppressed.

[0033]

In absorbent article

preferably, the absorbent component has a first layer and a second layer overlapping the first layer in the thickness direction and having a surface density that is lower than the surface density of the first layer, and

so that the first fold line and the second fold line are formed only on the second layer from the first layer and the second layer.

[0034]

According to the design of the absorbent article, a bending mark is formed only on the second layer, and a bending mark is not formed on the first layer having a high surface density. In contrast to the configuration in which a bending mark is formed on both the first layer and the second layer, the absorbent component tends to rise due to the bending mark, and a raised state of the outer lateral edge of the top sheet can be maintained. Therefore, it is possible to provide an effect of suppressing side leakage due to the bent portion of the top sheet.

[0035]

In absorbent article

preferably, the bonded portion is located externally in the width direction with respect to the first fold line and the second fold line in the front zone located on the front side of the crotch zone and in the rear zone located on the rear side of the crotch zone.

[0036]

According to the design of such an absorbent article, when pulling the wing toward the side of the undergarment of the undergarment, the area outside the width direction with respect to the first fold line and the second fold line tends to deform with the first fold line and the second fold lines as the places where the deformation begins and extend toward the side of the surface not facing the skin by means of the back sheet. In the crotch area, the bonded portion is located inside in the width direction with respect to the first fold line and the second fold line. For this reason, the bent parts located outside in the width direction with respect to the first bend line and the second bend line are located at a distance from the back sheet, and upon attachment, there is a tendency to maintain a raised state without pulling the bent parts toward the side not facing the skin surface. On the other hand, in the front zone and the rear zone, the bonded portion is located outside in the width direction W with respect to the first fold line and the second fold line, and the bonded portion that is located outside in the width direction with respect to the first fold line and the second fold line, it is pulled towards the side of the non-skin surface upon attachment and is deformed to an inclined state without maintaining the raised state. Therefore, the length of the top sheet in the width direction in the front zone and the back zone in the plan view in the attached state becomes larger than the length of the top sheet in the width direction in the crotch zone. The fluid released by the body can be absorbed in a wide area through the top sheet in the front zone and the back zone, and side leakage of the fluid released by the body can be suppressed.

[0037]

Consequently, thickening in the region of the bent portion 11 of the top sheet 10 can be maintained, and the user can get a comfortable sensation of absorbency.

[0053]

The depth of indentation of the indented portion 14 of the surface facing the skin in the thickness direction T is less than the depth of indentation of the indented portion 33 of the absorbent component in the thickness direction T. Since the indentation depth of the indented portion 14 of the skin-facing surface in the thickness direction is less than the indentation depth of the indented portion 33 of the absorbent component in the thickness direction, the surface roughness due to the indented portion of the skin-facing surface is small, and the thickening of the area in which the bent is located can be maintained Part 11. The user can get a comfortable feeling with respect to absorbency.

[0054]

The indentation depth of the indented part in the thickness direction is the depth of the indentation of the part in which the indented part is formed, relative to the part in which the indented part is not formed, and this depth can be measured, for example, by the following method. As a coordinate measuring machine for three-dimensional measurements, a high-precision shape measurement system (including a high-precision coordinate table: KS-1100) manufactured by Keyence Corporation and a high-speed and high-precision laser measuring device / sensor for determining displacements based on a charge-coupled camera (including controller in itself: LK-G 3000V set, measuring head: LK-G30). The absorbent article to be measured is placed on a horizontal plane, and the undulating state of the surface in cross section in the thickness direction is currently recorded as a contour. The depth is calculated based on the difference between the highest point and the lowest point, while in the part in which the recess is formed by the indented part, both portions end in the width direction are set as the highest point and the lower surface of the recess (lower surface of the indented part) is set as the lowest point.

[0055]

(3) Method for folding an absorbent article

The absorbent article 1 is adapted to be individually wrapped by the packing sheet 70. FIG. 3 is a view for describing a method of folding the absorbent article 1. The absorbent article 1 is placed on the packing sheet 70 so that the surface of the absorbent article 1 not facing the skin and the packing sheet 70 were facing each other when folding. One outer lateral edge of the absorbent article 1 and one outer lateral edge of the packaging sheet 70 are folded inwardly at the first fold line FL1 extending along the longitudinal direction L, as the starting point in the state in which the absorbent article 1 is located on the packaging sheet 70 (see FIG. 3A). In areas (areas on both sides of the first fold line FL1) arranged so that the first line FL1 is located between them in the unfolded state in which the absorbent article is unfolded (in the pre-folding state), parts of the surface facing the skin face each other in the folded state condition. A state in which parts of a skin-facing surface are facing each other is a state in which one part of a skin-facing surface is facing another part of a skin-facing surface and also encompasses a state in which another element is located between one part of the skin-facing to the skin surface and another part of the surface facing the skin.

[0056]

Further, the other outer lateral edge of the absorbent article 1 and the other outer lateral edge of the packaging sheet 70 are folded inwardly at the second fold line FL2 extending along the longitudinal direction L as the starting point (see FIG. 3B). In areas (areas on both sides of the second fold line FL2) arranged so that the second line FL2 is located between them in the unfolded state in which the absorbent article 1 is unfolded (the state before folding), parts of the surface facing the skin face each other in the folded state condition.

[0057]

Subsequently, in the folded state obtained by the first fold line FL1 and the second fold line FL2, the rear end edge of the absorbent article 1 and the rear end edge of the packaging sheet 70 are folded inwardly with the third fold line FL3 extending along the width direction W as the starting point. Further, the front end edge of the absorbent article 1 and the front end edge of the packaging sheet 70 are folded inwardly at the fourth fold line FL4 extending along the width direction W as the starting point (see FIG. 3C). With the folding described above, the length of the absorbent article 1 in the width direction and the length of the absorbent article in the longitudinal direction are reduced, and the absorbent article 1 is reduced in size. Therefore, it can be ensured the convenience of carrying in a compact state.

[0058]

In the unfolded state in which the folded absorbent article 1 is unfolded, a bending mark due to the first bending line FL1, the second bending line FL2, the third bending line FL3 and the fourth bending line FL4 is formed in the absorbent article 1. The bending mark, resulting from the first fold line FL1, and the bending mark resulting from the second fold line FL2, become bending marks that are removed from the carrier. The first fold line FL1 and the second fold line FL2 are fold lines in the depressions. Therefore, an area that is outside in the width direction with respect to the first bend line FL1 and the second bend line FL2, when unfolded, rises at the first bend line FL1 and the second bend line FL2 as elevation start points.

[0059]

The first fold line FL1 and the second fold line FL2 are located outside in the width direction W with respect to the folding line 12 of the top sheet 10. The first fold line FL1 and the second fold line FL2 are formed in an area in which only two layers of the base sheet 21 and the side are located of the sheet 22. A bending mark due to the first bending line FL1 and the second bending line FL2 is not formed in the area thickened by the two-layer top sheet 10. Therefore, the side portion of the top sheet 10 due to the bending mark will be difficult to lift, and will It is difficult to close the side of the absorbent component. The user can visually recognize the entire area, including the lateral part of the absorbent component, and get a comfortable sensation with respect to absorbency. In addition, a bending mark due to the first bending line FL1 and the second bending line FL2 does not form on the side of the absorbent component 30. Therefore, when the absorbent article 1 is folded out, the user can visually recognize the side part of the absorbent component and can easily recognize the actual the length of the absorbent component in the width direction. Therefore, the user can get a comfortable sensation regarding absorbency.

[0060]

(4) Modified Example

Next, an absorbent article 1A according to a modified example will be described with reference to FIG. 4. In the description of the modified example, the same reference numbers are used for the same configurations as in the above embodiment, and their description is omitted. The second sheet 15A of the absorbent article 1A according to the modified example extends outward in the width direction W beyond the outer side edge 30E of the absorbent component 30. In addition, the length of the second sheet 15A in the width direction W is greater than the length of the absorbent component 30 in the width direction W. According to the design of the absorbent article 1A according to the modified example, at least a two-layer top sheet and a single-layer second sheet 15A are arranged externally in the width direction with respect to the outer side edge 30E of the absorbent component 30. An area thickened by the three-layer sheet can be obtained externally in the width direction with respect to the outer side edge 30E of the absorbent component 30. The user feels that the body is excreted the fluid is properly absorbed into the thickened area, and the user can get a comfortable sensation regarding absorbency.

[0061]

The second sheet 15A of the absorbent article 1A according to the modified example has a bent portion 15B. The bent portion 15B is formed by bending the second sheet 15A toward the side of the non-skin surface along the bending line. The second sheet 15A forms a multilayer configuration in the thickness direction by means of its part, which extends (not bent) in the width direction between the bent part 15B and the bending line 12. The second sheet 15A forms two layers in the area in which the bent portion 15B is provided.

[0062]

According to the structure of the absorbent article 1A according to the modified example, a zone in which at least a two-layer top sheet and at least a two-layer second sheet are superposed are provided externally in a width direction with respect to the outer side edge 30E of the absorbent component 30. An area thickened by a four-layer sheet may be provided externally in a width direction with respect to the outer side edge 30E of the absorbent component 30. The user has the feeling that excreted by the body, the fluid is properly absorbed into the thickened area, and the user can get a comfortable sensation regarding absorbency. In addition, since the four-layer sheet is located externally in the width direction with respect to the outer side edge 30E of the absorbent component 30 released by the body, the fluid can be absorbed by the four-layer sheet. As the absorbent characteristic improves, the user can get a more comfortable sensation with respect to absorbency.

[0063]

Next, an absorbent article according to a second embodiment will be described.

JP 2001-70343 A discloses an absorbent article having a folded portion in which the top sheet is folded on both sides in a width direction. The absorbent article has an assembly valve that lifts the outer side edge of the absorbent component toward the side of the carrier. The outer side edge of the absorbent component and the folded portion of the top sheet are raised toward the side of the carrier during use. Lateral leakage of fluid released by the body is suppressed by raising the outer side edge of the absorbent component and the bent portion of the top sheet toward the side of the carrier.

[0064]

In the case of an absorbent article having a wing like an absorbent article according to JP 2001-70343 A, in use, the wing is bent toward the side of the undergarment of the undergarment. In this case, the outer lateral edge of the absorbent component and the bent portion of the upper sheet are pulled towards the side of the surface not facing the skin together with the wing. The bent portion of the top sheet cannot maintain the state in which it is raised toward the side of the carrier due to its pulling toward the side of the non-skin surface. Therefore, there may be a lack of suppression of lateral leakage of a fluid released by the body. It is preferable to make an absorbent product capable of maintaining the elevated state of the folded portion of the top sheet and suppressing the side leakage of the fluid released by the body.

[0065]

(5) General schematic configuration of an absorbent article

Next, the configuration of the second embodiment will be described. In the description below, the same reference numerals are used for the same configurations as in the first embodiment, and their description is omitted. 5 is a plan view of an absorbent article 1B according to a second embodiment. FIG. 6 is a sectional view of the absorbent article 1B taken along the line BB shown in FIG. The cross-sectional view shown in FIG. 6 is a plan view in an unfolded state in which the absorbent article 1B is folded out after the absorbent article 1B has been folded along the first fold line FL1 and the second fold line FL2, which will be described later. Therefore, a bending mark due to the first bending line FL1 and the second bending line FL2 is formed in the absorbent article 1B shown in FIG. 6.

[0066]

The absorbent component 30 has a first layer 31 and a second layer 32 overlapping the first layer 31 in the thickness direction T. The first layer 31 is located on the T1 side of the skin surface of the second layer 32. The surface density of the absorbent material of the first layer 31 is higher than the surface density of the absorbent material of the second layer 32. The length of the first layer 31 in the width direction W is less than the length of the second layer 32 in the width direction W.

[0067]

6 and 7 show that the back sheet 20 and the absorbent component 30 are separated from each other in the thickness direction, but the back sheet 20 and the absorbent component 30 of this embodiment are attached to each other by means of a fastening (not shown).

[0068]

As shown in FIG. 6, an adhesive part 80 for attaching an absorbent article 1B to an undergarment is provided on a non-skin surface of the base sheet 21. The adhesive part 80 includes two adhesive parts 81 of the main part located in the zone covering the absorbent component 30, two adhesive parts 82 of the wings located on the wings 3, and two parts for securing the valves (not shown) located on the pelvic valves 4. In the state before use, the adhesive part 80 is closed ovochnym sheet 70, intended to wrap the absorbent article individually.

[0069]

The absorbent article 1B is folded up similarly to the first embodiment (see FIG. 3). The first fold line FL1 and the second fold line FL2 are fold lines for folding the absorbent article so that parts of the skin-facing surface of the absorbent article face each other. In the unfolded state in which the absorbent article 1B is unfolded, a bending mark due to the first fold line FL1, the second fold line FL2, the third fold line FL3 and the fourth fold line FL4 is formed in the absorbent article 1B. The bending mark resulting from the first bending line FL1 and the bending mark resulting from the second bending line FL2 become bending marks that are removed from the carrier. The first fold line FL1 and the second fold line FL2 are fold lines in the depressions. Therefore, the area that is outside in the width direction with respect to the first bend line FL1 and the second bend line FL2, in the unfolded state rises at the first bend line FL1 and the second bend line FL2 as the lift start points (see FIG. 6).

[0070]

In addition, the first fold line FL1 and the second fold line FL2 are located inside in the width direction with respect to the outer side edge of the absorbent component 30. More specifically, the first fold line FL1 and the second fold line FL2 are located inside in the width direction with respect to the outer side edge the second layer and externally in the width direction with respect to the outer lateral edge of the first layer. The first fold line FL1 and the second fold line FL2 are formed on the second layer 32 and are not formed on the first layer 31.

[0071]

(6) Detailed configuration of the folded top sheet

The bent portion 11 is located in the thickness direction so that it faces the back sheet 20. The absorbent article 1B has a bonded portion in which the folded portion 11 and the back sheet 20 are bonded, and an unfastened portion 65 in which the folded portion 11 and the back sheet 20 are not bonded. The bonded portion has a first bonded portion 61 located at least in the crotch area S1, a second bonded portion 62 located on the front side of the first bonded portion 61, and a third bonded portion 63 located on the rear side of the first bonded portion 61. The first bonded portion part 61 is located in the entire area of the crotch zone S1 in the longitudinal direction L, on the part of the front zone S2 and on the part of the rear zone S3. The second bonded portion 62 is located in the front zone S2. The third bonded portion 63 is located in the rear zone S3. The non-bonded portion 65 is located in the width direction between the bonded portion and the bending line and in the width direction between the bonded portion and the end 11E of the folded portion 11.

[0072]

The first bonded portion 61 is located inside in the width direction W with respect to the first fold line FL1 and the second fold line FL2. That is, the bonded portion is located in the crotch zone S1 inside in the width direction with respect to the first fold line FL1 and the second fold line FL2 and is not located outside in the width direction with respect to the first fold line FL1 and the second fold line FL2. The area located outside in the width direction W with respect to the first fold line FL1 and the second fold line FL2 is configured such that the top sheet 10 can rise from the back sheet 20. The bent portion 11 of the top sheet 10 located outside in the width direction with respect to the first fold line FL1 and the second fold line FL2, rises at the first fold line FL1 and the second fold line FL2 as the starting points, so that lateral leakage of the fluid released by the body can be suppressed.

[0073]

The first bonded portion 61 is located inside in the width direction W with respect to the second bonded portion 62 and the third bonded portion 63. The first bonded portion 61 is located inside in the width direction with respect to the folding line 12. The first bonded portion 61 is located in the width direction with respect to the folding line 12 at a distance from the folding line 12. In the crotch zone S1, the loose part 65 is located in a certain region extending inward in the width direction from the bending line 12. In the region between the bending line 12 and the bonded portion, an unfastened portion 65 is located, and in this region, the folded portion 11 and the back sheet 20 are not attached to each other. Therefore, the region located between the bending line 12 and the first bonded portion 61 rises toward the side of the carrier due to a bending mark due to the first bending line FL1 and the second bending line FL2. Since the bent portion 11 of the top sheet 10 is raised toward the side of the carrier, lateral leakage of the body fluid released into the center of the top sheet 10 defined in the width direction can be suppressed.

[0074]

In the configuration according to the modified example, the first bonded portion 61 may be located outside in the width direction with respect to the first fold line FL1 and the second fold line FL2. In the modified example, it is preferable that the first bonded portion 61 is located externally in the width direction with respect to the intermediate point located between the first bend line FL1 and the bend line 12. This is because the bent portion 11 can rise relative to the back sheet in a certain area extending in the width direction from the bend line 12, and side leakage can be suppressed.

[0075]

In addition, the first fold line FL1 and the second fold line FL2 are located inside in the width direction W with respect to the outer side edge of the absorbent component 30 and are formed on the absorbent component 30. The bending mark becomes stronger, and the bent portion 11 of the top sheet 10 tends to to rise in contrast to a configuration in which a bend mark is not formed on the absorbent component 30. In addition, the stiffness of the part in which the first bend line FL1 and the second bend line FL2 are formed increases. The bent portion 11 of the top sheet 10 rises at the first bend line FL1 and the second bend line Fl2 as locations where the deformation begins. Since the rigidity of the lift start site is increased, it is easier to maintain the raised state of the bent portion 11 of the top sheet 10, and lateral leakage of the fluid released by the body can be suppressed.

[0076]

In addition, the first bend line FL1 and the second bend line FL2 are formed on the second layer 32 and not formed on the first layer 31. Therefore, the outer lateral edge of the second layer 32 can rise at the first bend line FL1 and the second bend line Fl2 as elevation start points. A bend mark due to the first bend line FL1 and the second bend line Fl2 is formed on the second layer 32 and does not form on the first layer 31 having a high surface density. In contrast to the configuration in which a bending mark is formed on both the first layer 31 and the second layer 32, the absorbent component tends to rise due to the bending mark, and the raised state of the outer lateral edge of the top sheet 10 can be maintained. Consequently, it is possible to provide side leakage suppression effect due to the bent portion 11 of the top sheet 10.

[0077]

(7) Method for attaching an absorbent article

Next, a method for attaching an absorbent article 1B made with the above configuration to an undergarment will be described. When the absorbent article 1B is attached to the underwear article S, first, the adhesive part 81 of the main body located in the center of the absorbent article 1B in the width direction W is attached to the underwear article S. In a state in which the absorbent article region, central in the width direction, is attached to the undergarment by the adhesive part 81 of the main part, the wing 3 is pulled towards the side T2 of the underwear surface of the undergarment, and thus the adhesive part 82 of the wing attached to the surface of the underwear not facing the skin. 7 is a sectional view of an absorbent article attached to an underwear article S.

[0078]

When the wing is pulled toward the side of the underwear surface not attached to the skin upon attachment, not only the wing is pulled out, but also the first bonded portion 61 located inside in the width direction with respect to the wing 3, and the curved portion 11 of the upper sheet 10 also is pulled out by the first bonded portion 61. The region between the folding line 12 of the top sheet 10 and the first bonded portion 61 is not attached to the back sheet 20. Therefore, when the wing 3 is pulled towards the side on T2 of the surface not facing the skin, the area near the bending line 12 does not extend toward the side of the surface not facing the skin together with the wing 3, and the raised state of the zone near the bending line 12 is maintained. Therefore, it is possible to maintain the elevated state of the bent portion 11 of the top sheet 10 and suppress the lateral leakage of the fluid released by the body.

[0079]

In addition, the second bonded portion 62 and the third bonded portion 63 are located outside in the width direction W with respect to the first fold line FL1 and the second fold line FL2. In at least a portion of the front zone S2 and at least a portion of the rear zone S3, a bonded portion is provided externally in a width direction with respect to the first fold line FL1 and the second fold line FL2.

[0080]

When pulling winglet 3 toward the side of the non-skin surface of the undergarment, the area that is outside in the width direction with respect to the first fold line FL1 and the second fold line Fl2 tends to deform with the first fold line FL1 and the second fold line FL2 as places of the beginning of deformation, and tends to extend toward the side T2 of the surface not facing the skin by means of a back sheet 20 located in the winglet. In the crotch zone S1, the first bonded portion 61 is located inside in the width direction W with respect to the first fold line FL1 and the second fold line FL2. For this reason, the curved portions 11 located outside in the width direction W with respect to the first bend line FL1 and the second bend line FL2 are located at a distance from the back sheet 20 and maintain a raised state without pulling them toward the side not facing the skin when attachment. On the other hand, in the front zone S2 and the rear zone S3, the second bonded portion 62 and the third bonded portion 63 are located outside in the width direction W with respect to the first fold line FL1 and the second fold line FL2, and the bent portion 11, which is located outside in the direction W of the width with respect to the first fold line FL1 and the second fold line FL2, is pulled toward the side T2 of the non-skin surface upon attachment and is deformed to an inclined state without maintaining a standing state. Therefore, the length of the top sheet 10 in the width direction W in the front zone S2 and the rear zone S3 in the plan view in the attached state will be greater than the length of the top sheet 10 in the width direction W in the crotch zone S1. The fluid released by the body can be absorbed in a wide area by the top sheet 10 in the front zone S2 and the back zone S3, and lateral leakage of the fluid released by the body can be suppressed.

[0081]

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in the form of modifications and changes without departing from the essence and scope of the present invention, defined by the scope of protection of the claims. Therefore, the description in the present description is intended to be illustrative and does not have any limiting value for the present invention.
