(1) Summary of embodiment

At least the following matters are clear from description of this specification and the attached drawings.

In the packaging body of the absorbent article according to one embodiment, the absorbent article is individually packaged by a packaging sheet. The absorbent article includes: a body adhesive portion having a body portion, a flap portion extending outward in a width direction than the body portion, and an adhesive disposed on the non-skin facing side of the body portion and fixing the body portion to the undergarment; A flap adhesive portion disposed on the side of the non-skin facing side of the flap portion and having an adhesive for fixing the flap portion to the undergarment; a body release sheet covering the body adhesive portion and bonded through the packaging sheet and the body fixing portion; It has a flap release sheet covering the flap adhesive part in a state where the flap part is folded toward the skin-facing surface side of the main body part. The package body is folded to the inside of the package body based on a first folding line extending in the width direction, which is an outer end edge of the package body in the front and rear direction, and is also folded with the first folding line as a starting point. In this state, the second folding line extending in the width direction and positioned on the second end edge side opposite to the first end edge is folded to the inside of the package body. At least a portion of the flap adhesive portion and the flap release sheet is disposed on the second edge side of the second fold line. In a third folded state folded with the second folding line as a starting point, in a region where the packaging sheet and the flap release sheet face each other, a flap fixing portion for bonding the packaging sheet and the flap release sheet is provided. In the third folded state, the main body fixing portion and the flap fixing portion overlap in the thickness direction.

In a conventional packaging body for an absorbent article, a body release sheet and a packaging sheet are disposed on the non-skin side of the absorbent article. When the main body adhesive portion is peeled from the main body release sheet when the absorbent article is unfolded, the packaging sheet is pulled in the spreading direction with respect to the absorbent article by holding the front end portion of the packaging sheet such as a tag tape. However, the body adhesive portion of the absorbent article is in contact with the body release sheet, not the packaging sheet. Therefore, when the packaging body is unfolded, even if the packaging sheet is pulled in the unfolding direction with respect to the absorbent article, the force in the unfolding direction is not properly applied to the body release sheet, making it difficult to peel the body release sheet from the body adhesive portion. In some cases, the flap release sheet was difficult to peel from the flap adhesive portion. Therefore, the package body according to the present embodiment is configured so that the main body release sheet is easily peeled from the main body adhesive portion, and the flap release sheet can be easily peeled from the flap adhesive portion when the package body is unfolded.

According to this aspect, when the package body is unfolded from the third folded state to the second folded state, since the body fixing portion and the flap fixing portion are overlapped in the thickness direction, the body peeling sheet and the absorbent property from the packaging sheet through the body fixing portion By transmitting a force to the article, the package body is unfolded from the second fold line, and the flap release sheet can be pulled away from the flap adhesive portion through the flap fixing portion. Accordingly, the main body release sheet can be easily peeled from the main body adhesive portion, and the flap release sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the main body fixing part and the flap fixing part, in a state in which the package body is folded from the first fold line and the second fold line, before and after the second fold line and the first fold line It may be arranged on the side of the first folding line rather than the center of the direction.

According to this aspect, when the package body is unfolded from the second fold line, the main body fixing portion and the flap fixing portion are separated from the second fold line serving as the rotation axis, and thus the second fold line side is centered by pulling the packaging sheet. As a result, the first folding line side is easy to move in the rotation direction.

According to a preferred embodiment, the flap portion is provided in a pair on both sides of the body portion in the width direction, the flap adhesive portion is provided on each of the pair of flap portions, and the flap portion is folded toward the skin-facing surface side of the body portion It is spaced apart from each other in a state, the flap release sheet covers the pair of flap adhesive portions, and the flap fixing portion may be overlapped with a region between the pair of flap adhesive portions in the thickness direction.

When the packaging body is unfolded from the second fold line, when the user pulls the packaging sheet, the flap release sheet moves so as to be separated from the flap adhesive portion. At this time, since the flap adhesive portion and the flap fixing portion do not overlap, the region in contact with the flap fixing portion in the flap release sheet moves first, and the region in contact with the flap adhesive portion in the flap release sheet follows and moves. The tip end of each flap part stands up with the base part of each flap as a starting point, and is arrange|positioned so that a substantially triangular space may be surrounded by a pair of flap parts and a body part.

In a state in which the flap portion and the absorbent article are arranged to form a triangle, the center of the flap release sheet in the width direction (a portion overlapping with the flap fixing portion) is pulled toward the packaging sheet side, and the flap release sheet is curved. At this time, the flap release sheet is pulled at the same time as the packaging sheet, thereby attempting to maintain a flat state. As a result, the outer edge of the flap adhesive portion in the state in which the flap portion is folded over the body portion begins to peel from the flap release sheet. The flap release sheet gradually falls off the flap adhesion part, and the flap release sheet can be easily peeled off from the flap adhesion part.

According to a preferred embodiment, the length of the flap fixing portion in the width direction may be longer than that of the body fixing portion in the width direction.

According to this aspect, when unfolding the package body from the second folding line as a starting point, the flap release sheet can be pulled in the peeling direction in a wide range in the width direction through the flap fixing portion. Accordingly, the flap release sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the length of the flap fixing portion in the width direction may be shorter than that of the body fixing portion in the width direction.

According to this aspect, when the tip end of each flap is deformed so as to stand up with respect to the root of each flap, the tip of each flap is further pulled toward the center side in the width direction of the body portion, so that the standing angle of the flap can be increased. Therefore, the flap peeling sheet can be peeled more easily from the flap adhesive part.

According to a preferred embodiment, the flap fixing portion may be disposed to be spaced apart from the flap adhesive portion in the width direction in a region between the pair of flap adhesive portions.

According to this aspect, the standing angle of the flap can be further increased, and the flap release sheet can be easily peeled off from the flap adhesive portion.

According to a preferred embodiment, the flap adhesive portion includes a first flap adhesive portion, and a second flap adhesive portion positioned inside the width direction than the first flap adhesive portion in the deployed state of the absorbent article, and the An edge of the first flap adhesive portion on the side of the second edge may be disposed at a side of the second edge of the second flap adhesive portion than an edge on the side of the second edge of the second flap adhesive portion.

According to this aspect, the edge on the side of the second edge of the flap adhesive portion becomes a side separated from the second folding line serving as the deployment starting point when the package is unfolded from the second folding line. The second flap adhesive portion positioned on the proximal side of the flap portion extends from the first flap adhesive portion positioned on the distal end side of the flap portion to a side separated from the deployment starting point. Therefore, when the tip end of each flap is deformed so as to stand up with respect to the root of each flap, the tip side of the flap is more likely to rise earlier than the base side of the flap portion. By increasing the standing angle of the flap portion, the outer edge of the flap adhesive portion and the flap peeling sheet are gradually peeled off, so that the flap peeling sheet can be more easily peeled from the flap adhesive portion.

According to a preferred embodiment, the body fixing portion may have a first body fixing portion disposed in a first area on the first edge side of the first folding line.

According to this aspect, since the packaging sheet and the body release sheet are joined in the first body fixing portion in the first region on the first edge side of the first folding line, the packaging sheet is developed so as to develop from the second folding line as a starting point. When pulled, the absorbent article becomes easier to develop through the packaging sheet and the body release sheet.

According to a preferred embodiment, the main body fixing part, the first body fixing part, and a second body fixing part disposed in a second area between the first folding line and the second folding line in the unfolded state of the package body You may have

According to this aspect, in both the first region and the second region, the packaging sheet and the body release sheet are joined by the body fixing portion. When a force is applied to the first fold line side through the packaging sheet so as to develop from the second fold line as a starting point, force can be applied to both sides of the first fold line between them, so that it is absorbent through the packaging sheet and the body release sheet. The article becomes easier to deploy.

According to a preferred embodiment, the first body fixing portion and the second body fixing portion may overlap in the thickness direction in the third folded state.

According to this aspect, when a force is applied to both sides of the first body fixing portion and the second body fixing portion sandwiching the first folding line, the force is easily transmitted, and absorbability through the packaging sheet and the body peeling sheet The article becomes easier to deploy.

A package for an absorbent article according to another aspect is a package for an absorbent article in which the absorbent article is individually packaged by a packaging sheet. The absorbent article includes: a body portion having an absorbent core; a pair of flap portions extending outwardly in a width direction than the body portion; and an adhesive that is disposed on a side of the non-skin facing surface of the body portion, and fixes the body portion to the underwear And a pair of flap adhesive portions having an adhesive that is disposed on the non-skin side of each flap portion and fixes the body portion to the undergarment, and the flap portion is folded toward the skin-facing surface of the body portion. And a flap release sheet covering the pair of flap adhesive portions. The package body, in a first folded state in which the flap portion is folded toward the skin-facing surface side of the body portion, a first folding line extending in the width direction of the first unit edge, which is an outer edge of the package body in the front-rear direction, as a starting point. A second folded inward of the package body, extended in the width direction in a second folded state folded with the first folding line as a starting point, and positioned on a second edge side opposite to the first edge It is folded into the inside of the package body from the fold line. At least a portion of the flap adhesive portion and the flap release sheet is disposed on the second edge side of the second folding line. In a third folded state folded with the second fold line as a starting point, a flap fixing portion for bonding the packaging sheet and the flap release sheet is provided in a region where the packaging sheet and the flap release sheet face each other. The absorbent core has a low unit weight portion of which the unit weight of the absorbent core is lower than that of its surroundings. The low unit weight portion has a second low unit weight region extending in a front-rear direction on the second unit edge side than the second fold line.

In the conventional packaging body of an absorbent article, the packaging sheet is pulled in the unfolding direction through the vicinity of the front end portion of the packaging body such as a tag tape, while unfolding the absorbent article, the flap release sheet is pulled together with the packaging sheet. However, since the flap release sheet is in contact with the flap adhesion part, the flap part is easily deformed so as to follow the flap release sheet through the flap adhesion part. When the flap part follows the flap release sheet, the tip end of the flap part rises with respect to the root of the flap part. In this state, when the flap release sheet is pulled together with the packaging sheet, when the flap release sheet slides in the width direction with respect to the flap part, shear stress is generated by the flap adhesion part. Therefore, there was a case where it was difficult to peel the flap release sheet from the flap adhesive portion. Therefore, the package body according to this aspect is configured so that the flap release sheet can be easily peeled from the flap adhesive portion.

According to this aspect, when unfolding the package body from the second fold line, when a force is applied to the first fold line through the packing sheet, the package body is centered on the second fold line, and is more than the second fold line. With respect to the region on the second edge side, the region on the side of the first fold line rather than the second fold line moves in the rotation direction, and the flap release sheet moves in the rotation direction along with the packaging sheet according to the movement. At this time, the region on the second edge side of the second fold line is more likely to bend in the width direction due to the deformation starting point extending in the front-rear direction by the second low unit weight region. Accordingly, when the flap portion is pulled through the flap release sheet and the flap adhesive portion, the base portion of the flap portion moves inward in the width direction. The flap release sheet is pulled together with the packaging sheet in the spreading direction, and tries to maintain a flat state. On the other hand, as the flap portion moves inward in the width direction of the base portion of the flap portion, the angle to stand up from the skin-facing surface side of the absorbent article increases. Therefore, the flap release sheet and the flap part are easily separated in the development direction, the outer edge of the flap adhesion part is peeled from the flap release sheet, and the flap release sheet can be easily peeled from the flap adhesion part.

According to a preferred embodiment, the low unit weight portion has a front and rear low unit weight region parallel to the front and rear direction, and the front and rear low unit weight region is on the first unit edge side than the first fold line in the deployed state. It does not have to be provided in the realm of.

According to this aspect, when expanding the second fold line as a starting point, the area on the side of the first fold line rather than the second fold line is moved in the rotational direction with respect to the area on the second edge side of the second fold line. In this case, the region between the first fold line and the flap fixing portion is less likely to be deformed inward in the width direction, and the region on the second end edge side is relatively more easily deformed toward the inside in the width direction than the second fold line. Therefore, when the flap portion is pulled through the flap release sheet and the flap adhesive portion, the base portion of the flap portion moves inward in the width direction, and the standing angle of the flap portion tends to be large.

According to a preferred embodiment, the front and rear low unit weight regions may not be provided in a region between the first fold line and the second fold line in the deployed state.

According to this aspect, when developing the second fold line as a starting point, the area on the first edge side of the second fold line is less likely to be deformed, and the area on the second side edge side than the second fold line is relatively inside the width direction. It becomes easy to deform. Therefore, when the flap portion is pulled through the flap release sheet and the flap adhesive portion, the base portion of the flap portion moves inward in the width direction, and the standing angle of the flap portion tends to be large.

According to a preferred embodiment, the second side low unit weight area and the flap fixing part are disposed on the first fold line side rather than the center of the front and rear directions of the second fold line and the first fold line in the third fold state. May be.

According to this aspect, the flap fixing part is separated from the second folding line which becomes the rotation axis when the second folding line is unfolded as a starting point, and the flap release sheet is moved in the unfolding direction by pulling the packaging sheet at the time of deployment. It becomes easy to move. At this time, since the deformation starting point due to the second low unit weight region is provided on the side of the first fold, the angle of standing of the flap portion on the side of the first fold can be further increased.

According to a preferred embodiment, the low unit weight portion has a first side low unit weight region disposed on the first unit edge side than the first fold line in the deployed state, and the first side low unit weight region is unfolded. In a region between the first folding line and the flap fixing portion in a state, it may extend outward in the width direction toward the first folding line side.

According to this aspect, a deformation starting point extending outward in the width direction toward the first folding line side is formed in the region between the first folding line and the flap fixing portion. From the cross section in the thickness direction, the absorbent core on the flap release sheet side rather than the flap fixing part extends outward in the width direction from the flap fixing part toward the first fold line by the deformation origin by the first side low unit weight region. An origin of deformation is formed. Accordingly, when the flap release sheet is pulled by the packaging sheet, the flap release sheet also forms a deformation starting point extending outward in the width direction from the flap fixing portion toward the first folding line. The flap release sheet is deformed so as to be spaced apart from the flap adhesion part, so that the flap release sheet can be easily released from the flap adhesion part.

According to a preferred embodiment, it has a main body release sheet that covers the main body adhesive part and is bonded to the packaging sheet through a main body fixing part, and the main body fixing part is on the first end edge side than the first fold line in the deployed state. And the low unit weight portion may have an intermediate low unit weight region positioned in a region between the first fold line and the second fold line in an expanded state.

According to this aspect, the force applied to the packaging sheet is transmitted to the body release sheet through the body fixing portion. The main body release sheet is in contact with the main body adhesive portion of the absorbent article, so that force is easily transmitted to the absorbent article. Therefore, in the third folded state, when the user applies a force to the first fold line through the packing sheet, the force is transmitted to the main body release sheet through the main body fixing portion, and the main body is centered on the second fold line. The negative first folding line side is easy to move in the rotation direction. In the third folded state, when the side of the first fold line of the main body moves in the rotational direction around the second fold line, the absorbent core in the region between the first fold line and the second fold line starts from the middle low unit weight region. Transformed. As the absorbent core in the region between the first fold line and the second fold line is deformed, the flap release sheet is deformed so as to be spaced apart from the flap adhesive part, so that the flap release sheet can be easily peeled from the flap adhesion part.

According to a preferred embodiment, the second low unit weight region may extend in the width direction in a region on the second end edge side than the flap fixing portion in the deployed state.

According to this aspect, since the second low unit weight region extends in the width direction in the region on the second unit edge side than the flap fixing portion, it is possible to absorb distortion by the second low unit weight region. . Even when the packaging sheet cannot be pulled substantially vertically with respect to the second unit edge of the absorbent article, the second side low unit weight region absorbs the distortion, and the flap release sheet can be pulled substantially vertically with respect to the flap adhesive portion. Accordingly, the flap release sheet can be easily peeled from the flap adhesive portion.

According to a preferred embodiment, the second low unit weight region may extend in the width direction in the region between the flap fixing portion and the first folding line in the deployed state.

According to this aspect, the region between the flap fixing portion and the first folding line is more likely to be applied with a force in the unfolding direction in the fourth unfolding step. Since the second low unit weight region is provided in the region between the flap fixing portion and the first folding line in the deployed state, the effect of absorbing the distortion of the body portion is more easily obtained.

According to a preferred embodiment, the second low unit weight region may reach the outer edge of the absorbent core.

According to this aspect, the area on the second unit edge side of the absorbent article and the area overlapping with the flap fixing portion can be divided by the second side low unit weight area, so that the effect of absorbing distortion of the body portion is more easily obtained. .

Further, the absorbent article packaging body according to another aspect is a packaging body for an absorbent article in which the absorbent article is individually packaged by a packaging sheet. The absorbent article includes a body portion, a pair of flap portions extending outward in a width direction than the body portion, and a pair of adhesives disposed on the non-skin facing side of the flap portion, respectively, to fix the flap portion to the undergarment. A flap adhesive portion and a flap release sheet covering the flap adhesive portion in a state in which the flap portion is folded toward the skin-facing surface of the main body portion is provided. The package body, in a first folded state in which the flap portion is folded toward the skin-facing surface side of the body portion, a first folding line extending in the width direction of the first unit edge, which is an outer edge of the package body in the front-rear direction, as a starting point. A second folded inward of the package body, extended in the width direction in a second folded state folded with the first folding line as a starting point, and positioned on a second edge side opposite to the first edge The fold line is folded into the inside of the package. At least a portion of the flap adhesive portion and the flap release sheet is disposed on the second end edge side of the absorbent article rather than the second fold line. In a third folded state folded with the second fold line as a starting point, a flap fixing portion for bonding the packaging sheet and the flap release sheet is provided in a region where the packaging sheet and the flap release sheet face each other. The body portion has an absorbent core, a top sheet positioned on the skin-facing surface side of the absorbent core, and an upright leak-proof gathers positioned on the skin-facing surface side of the top sheet.

In the deployment process 4, the package body 110 is unfolded from the third folded state to the second folded state. In the third folded state folded with the second folding line FL2 as a starting point, the packaging sheet 100 and the flap release sheet 76 are joined via the flap fixing portion 92. Therefore, when the package body 110 is unfolded from the third folded state to the second folded state, the flap release sheet 76 is pulled away from the wing adhesive portion 72 through the packing sheet 100. In more detail, the user moves the packaging sheet 100 in the rotation direction X14 around the second fold line FL2. Thereby, as shown in FIG. 14, the packaging sheet 100, the main body part 2, and the flap release sheet 76 move in the rotational direction X14, and the flap release sheet 76 is the wing adhesive part 72 Move away from ). 14 is a state in which the flap release sheet moves in the rotational direction, and the flap release sheet is separated from the wing adhesive portion 72 like a packaging sheet.

The user further pulls the packaging sheet 100 so that the packaging sheet 100 and the absorbent article 1 are not folded at the second folding line FL2 as a starting point, but are in an unfolded state (unfolding step 5). In the state shown in Fig. 15, only the flap release sheet 76 is folded at the second fold line FL2, and the other members are in the first folded state not folded at the second fold line FL2. In this state, the flap release sheet 76 is in contact with the hip flap adhesive portion 73 located in the second region R12. In the cross section shown in FIG. 15, the hip flap adhesive portion 73 does not appear, but a position corresponding to the hip flap adhesive portion 73 is virtually shown.

Subsequently, as shown in FIG. 16, the user moves the packaging sheet 100 in the rotational direction X161 with the 1st folding line FL1 as a starting point (expanding process 6). At this time, the main body release sheet 75 and the flap release sheet 76 disposed with the packaging sheet 100 interposed therebetween move in the rotational direction X161 with the first folding line FL1 as a starting point. In the first region R11, the main body release sheet 75 is peeled from the main body adhesive portion 71. At this time, the flap release sheet 76 positioned at the rear edge of the second fold line FL2 is in contact with the hip flap adhesive portion 73 of the second region R12. Therefore, when the user pulls the packaging sheet 100 further, the packaging body 110 will rotate in the rotation direction X162 (FIG. 16) and the rotation direction X17 (FIG. 17) based on the first folding line FL1. Move to) (deployment process 7). FIG. 17 shows a state in which the area on the rear edge side of the packaging sheet 100 and the absorbent article 1 is moved in the rotation direction X17 based on the first fold line FL1. Is shown. The user peels the main body release sheet 75 and the flap release sheet 76 together with the packaging sheet 100 to expose the main body adhesion part 71, the wing adhesion part 72, and the hip flap adhesion part 73. I can make it. According to this unfolding method, the user starts to unfold by holding the package body 110 near the tag tape 102 and the vicinity of the front end edge of the absorbent article 1, without fixing his hand until unfolding is completed, The packaging sheet 100 and the absorbent article can be separated.

In the above-described deployment step 4, depending on the user, the packaging sheet 100 and the absorbent article 1 are held in the vicinity of the first fold line FL1, and the first fold line FL2 is used as a starting point. The package body near the fold line FL1 can be moved in the direction of rotation. When deployed in this manner, the force for spreading the packaging sheet 100 is easily transmitted to the flap fixing portion 92, and the flap release sheet 76 can be easily peeled from the wing adhesive portion 72.

However, depending on the user, the wrapping sheet 100 is pulled and unfolded by holding the front edge 100F side of the packaging sheet 100 following the unfolding process 3 before that, as in the unfolding process 4 described above. Specifically, for example, by holding the shear edge 1F of the absorbent article 1 with one hand and the shear edge 100F of the packaging sheet 100 with the other hand, the first folding line FL1 ) And the front edge 1F of the absorbent article 1, the packaging sheet 100 is peeled from the body adhesive portion 71 (deployment step 3), and the packaging sheet 100 and the absorbent article ( 1) is gripped, and a force is applied to the first folding line FL1 through the packaging sheet 100 to unfold the package body 110 (unfolding step 4). In this way, the packaging body 110 of the absorbent article according to the present embodiment holds the packaging sheet 100 in the unfolding step 4 to unfold the packaging body 110 by using the body release sheet 75 as the body. It is configured to be easily peeled from the adhesive portion 71, and the flap peeling sheet 76 can be easily peeled from the wing adhesive portion 72.

As described above, in the unfolding process 4, when a force is applied to the first fold line FL1 through the packing sheet 100, the package body 110 is centered on the second fold line FL2. The first folding line FL1 side moves in the rotation direction X14 (FIG. 14), and according to the movement, the flap release sheet 76 together with the packaging sheet 100 moves in the rotation direction X14. The flap release sheet 76 is separated from the wing adhesive portion 72 in the three regions R13.

When moving the first folding line FL1 side in the rotational direction X14 centering on the second folding line FL2 side, the entire absorbent article 1 as well as the packaging sheet 100 is moved in the rotational direction. Need to move. Even if a force is applied only to the packaging sheet 100, if the absorbent article 1 does not move in the rotational direction X14, the force to move in the front-rear direction (L) is applied only to the packaging sheet 100, and the flap fixing portion 92 ) Through the flap release sheet 76 can not be pulled in the direction away from the wing adhesive portion 72. As a result, shear stress is generated by the wing adhesive portion 72 in contact with the flap peeling sheet 76, and it is difficult for the flap peeling sheet 76 to fall from the wing adhesive portion 72 in the third region R13. There is a risk of losing.

In the package body 110 according to the present embodiment, the force applied to the packaging sheet 100 is transmitted to the main body release sheet 75 through the main body fixing portion 91. This is because the main body release sheet 75 is in contact with the main body adhesive portion 71, and it is easy to transmit a force to the absorbent article 1. When a user applies a force to the first folding line FL1 through the packaging sheet 100 in the rotation direction X14, the force is transmitted to the main body release sheet 75 through the main body fixing portion 91, The side of the first fold line FL1 of the absorbent article 1 easily moves in the rotation direction X14.

The main body fixing part 91 overlaps the flap fixing part 92 in the thickness direction T. Therefore, force is transmitted from the packing sheet 100 to the main body release sheet 75 and the absorbent article 1 through the main body fixing part 91, and the packing sheet 100 and the main body release sheet 75 rotate in the direction of rotation ( When moving to X14), the flap release sheet 76 is also easily moved in the rotational direction X14, and the flap release sheet 76 can be easily peeled off from the wing adhesive portion 72. Accordingly, the main body release sheet 75 can be easily peeled from the main body adhesive portion 71, and the flap release sheet 76 can be easily peeled from the wing adhesive portion 72.

The body fixing part 91 and the flap fixing part 92 are in a third folded state in which the package body 110 is folded with the first folding line FL1 and the second folding line FL2 as a starting point, The fold line FL2 and the first fold line FL1 may be disposed on the first fold line FL1 side than the center of the front-rear direction L. The center of the front-rear direction L of the 2nd fold line FL2 and the 1st fold line FL1 becomes the center of the front-rear direction of the 3rd area|region R13. Since the main body fixing part 91 and the flap fixing part 92 are separated from the second folding line FL2 serving as the rotation axis in the unfolding process 4, the second folding line FL2 is removed in the unfolding process 4. As the center, the first folding line FL1 side tends to move in the rotation direction. In addition, at least a portion of the main body fixing portion 91 and at least a portion of the flap fixing portion 92 are first folded from the center of the front-rear direction L of the second folding line FL2 and the first folding line FL1. It may be arranged on the side of the line FL1. More suitably, the body fixing part 91 and the flap fixing part 92 are the first folding line FL1 than the center of the front-rear direction L of the second folding line FL2 and the first folding line FL1. It is desirable to be convenient to the) side.

The flap fixing portion 92 is a pair in the thickness direction T in the third folded state in which the package body 110 is folded with the first folding line FL1 and the second folding line FL2 as a starting point. It may be overlapped with the area between the wing adhesive portions 72 of. When the flap release sheet 76 moves away from the wing adhesive part 72 in the development process 4, the area in contact with the flap fixing part 92 in the flap release sheet 76 first moves, and the flap release sheet The area in contact with the wing adhesion portion 72 in (76) follows and moves. This is because the wing adhesive portion 72 and the flap fixing portion 92 did not overlap. 18 and 20, the tip of each wing 3 moves in the rotational direction X18 with the root of each wing as a starting point, and stands up from the skin-facing surface side T1 of the absorbent article 1 . It is arranged so as to surround a substantially triangular space by a pair of wings 3 and the body portion 2.

In a state in which the wing 3 and the main body 2 are arranged to form a triangle, the center of the flap release sheet 76 in the width direction W (the part overlapping the flap fixing part 92) is the packaging sheet ( It is pulled to the 100) side, and the flap release sheet 76 is curved. However, the flap release sheet 76 tries to maintain a flat state by being pulled together with the packaging sheet 100. Therefore, in the unfolding step 4, the flap release sheet 76 is moved in a state in which the tip end of the wing 3 is deformed to stand up from the root of the wing, so that the wing adhesion portion 72 in the first folded state is The outer edge begins to peel from the flap release sheet 76. The flap release sheet 76 is gradually separated from the wing adhesive portion 72, and the flap release sheet 76 can be easily peeled off from the wing adhesive portion 72.

The length of the flap fixing part 92 in the width direction W may be shorter than the length of the main body fixing part 91 in the width direction W. When the tip of each wing (3) is deformed to stand with respect to the root of the wing (3) in the development step 4, the tip of each wing is further pulled toward the center of the width direction (W) of the body (2), and the wing (3) The standing angle can be increased. Accordingly, the flap release sheet 76 can be more easily peeled from the wing adhesive portion 72.

In another aspect, the length of the width direction W of the flap fixing part 92 may be longer than the length of the width direction W of the main body fixing part 91. In the development process 4, the flap release sheet 76 can be pulled out in the spreading direction in a wide range in the width direction through the flap fixing part 92. Therefore, the flap release sheet 76 can be peeled off from the wing adhesive portion 72.

The flap fixing part 92 may be arranged to be spaced apart from the wing adhesion part 72 in the width direction in the region between the pair of wing adhesion parts 72. When the tip end of each wing 3 is deformed so as to stand with respect to the root of the wing 3 in the development step 4, the angle of standing of the wing 3 can be further increased. Therefore, the flap peeling sheet 76 can be peeled more easily from the wing adhesive part 72.

The front edge of the first wing adhesive portion 721 may be disposed behind the front edge of the second wing adhesive portion 722. The front edge, which is the edge on the second end edge side of the wing adhesion portion 72, becomes a side separated from the second folding line FL2 serving as an unfolding starting point in the unfolding step 4. The second wing adhesive portion 722 positioned at the base side of the wing 3 is farther from the second folding line FL2 than the first wing adhesive portion 721 positioned at the tip side of the wing 3 It is extended. In the first folded state in which the wing 3 is folded to the skin-facing surface side of the body portion 2, the length of the wing adhesive portion located inside the width direction in the front-rear direction is short. Therefore, when the tip end of each wing 3 is deformed to stand with respect to the root of each wing 3, the tip side of the wing 3 is more likely to rise earlier than the root side of the wing 3. By increasing the standing angle of the wing 3, the outer edge of the wing adhesive part 72 and the flap release sheet 76 are gradually peeled off, and the flap release sheet 76 is more easily peeled from the wing adhesive part 72. can do.

Further, the second low unit weight region R41 of the low unit weight portion 34 may extend in the front-rear direction L on the front edge side than the second fold line FL2. The absorbent core 31 in the region on the front edge side of the second folding line FL2 is formed with a deformation starting point extending in the front-rear direction L by the second low unit weight region R41, and the width direction ( It becomes easy to bend with W). Therefore, in the development step 4, when the wing 3 is pulled through the flap release sheet 76 and the wing adhesive portion 72, the width direction W of the region on the front edge side of the second fold line FL2 The center of is deformed so that it is separated from the flap release sheet 76. The absorbent core 31 in the region on the front edge side of the second fold line FL2 is deformed into a curved shape. As a result, as shown in FIG. 18, the root of the wing 3 located in the region on the front edge side of the second fold line FL2 moves to the inside of the width direction W, and the wing 3 stands up. The angle increases. Therefore, the tip of each wing stands up from the root of each wing, and is arranged so as to surround a substantially triangular space by the pair of wings 3 and the body portion 2. As described above, the outer edge of the wing adhesive portion 72 in the first folded state starts to peel from the flap release sheet 76. The flap release sheet 76 is gradually separated from the wing adhesive portion 72, and the flap release sheet 76 can be easily peeled off from the wing adhesive portion 72.

Further, the front and rear low unit weight regions R42 of the low unit weight portion 34 may not be provided in the first region R11 on the rear edge side of the first folding line FL1 in the deployed state. In the development step 4, when expanding the second fold line FL2 as a starting point, the first fold line FL1 is more than the second fold line FL2 in the area on the front edge side of the second fold line FL2. Move the area on the) side in the direction of rotation. At this time, since the area between the first fold line FL1 and the flap fixing part 92 is difficult to deform in the width direction, the area on the front edge side is relatively more than the second fold line FL2 in the width direction. It becomes easy to deform inward. Therefore, when the wing 3 is pulled through the flap release sheet 76 and the wing adhesive portion 72, the root of the wing moves inward in the width direction (W), and the standing angle of the wing 3 is likely to increase. . Accordingly, the flap release sheet 76 can be easily peeled from the wing adhesive portion 72.

In another aspect, the front and rear low unit weight regions R42 may not be provided also in the second region R12. That is, the front and rear low unit weight regions R42 may not be provided in a region between the first fold line FL1 and the second fold line FL2 in the expanded state. Since the front and rear low unit weight regions R42 are not provided in both the first region R11 and the second region R12, in the unfolding step 4, the first unit edge side of the second fold line FL2 The region becomes more difficult to deform, and the region on the front edge side is relatively more easily deformed toward the inside of the width direction W than the second fold line FL2. Therefore, when the wing 3 is pulled through the flap release sheet 76 and the wing adhesive portion 72, the base portion of the wing 3 moves inward in the width direction, so that the standing angle of the wing 3 is likely to increase. . Therefore, the rising angle of the wing 3 is further increased, and the flap peeling sheet 76 can be easily peeled off from the wing adhesion portion 72.

The second side low unit weight region R41 and the flap fixing portion 92 are in a third folded state in which the package 110 is folded with the first folding line FL1 and the second folding line FL2 as a starting point. In this case, the second folding line FL2 and the first folding line FL1 may be disposed on the first folding line FL1 side than the center of the front-rear direction L. The flap fixing part 92 is separated from the second fold line FL2, which becomes the rotation axis when the second fold line FL2 is unfolded as a starting point, and by pulling the packaging sheet 100 at the time of deployment, , It becomes easy to move the flap release sheet 76 in the developing direction. At this time, since the deformation starting point due to the second low unit weight region R41 is provided on the first folding line FL1 side, the standing angle of the wing 3 on the first folding line FL1 side is further increased. You can make it big.

The first side low unit weight region R43 of the low unit weight portion 34 is a first fold line FL1 in the region between the first fold line FL1 and the flap fixing portion 92 in the unfolded state. It may extend outward in the width direction W toward the side. In a region between the first folding line FL1 and the flap fixing part 92, a deformation starting point extending outward in the width direction W toward the first folding line FL1 is formed. When viewed from the cross section in the thickness direction, the absorbent core 31 on the flap release sheet side than the flap fixing part 92 is removed from the flap fixing part 92 by the deformation starting point due to the first low unit weight region R43. 1 A deformation starting point extending outward in the width direction W toward the fold line FL1 is formed. Therefore, when the flap release sheet 76 is pulled through the packaging sheet 100 in the development step 4, the flap release sheet 76 also has a width from the flap fixing portion 92 toward the first fold line FL1. A deformation origin extending outward in the direction W is formed. The flap release sheet 76 is deformed so as to be spaced apart from the wing adhesion part 72, so that the flap release sheet 76 can be easily removed from the wing adhesion part 72.

The package body of the present embodiment is configured to suppress a problem in which the wing adhesive portion 72 as the flap adhesive portion is unintentionally adhered in the fourth unfolded state. Specifically, the outer edge 622E of the folded back portion 622 may be disposed outside the absorbent core 31 in the width direction. The fold-back portion 622 of the contraction portion 62 has a leak-preventing elastic member 61, and the outer side in the width direction from the inner edge of the extension portion 621 in the central region S3. Stand to the side.

As shown in Fig. 21, in a state in which the wing 3 is folded with the flap fold line FL5 as the starting point, between the wing 3 and the body portion 2 disposed with the flap fold line FL5 interposed therebetween. , The leakage prevention gathers 60 are arranged. Therefore, the inner surface of the wing 3 in the folded state (the skin-facing surface side in the expanded state) is disposed to face the outer edge 622E of the folded portion 622. As shown in Fig. 22, in the development step 4, when the wing 3 is pulled together with the flap release sheet 76 and moved to the inside (X221) in the width direction (W), it is placed on the inner surface of the wing (3). The outer edge 622E of the folding part 622 abuts, and movement of the wing 3 to the inside in the width direction can be regulated. 22 shows a state in which the outer edge 622E of the bent portion 622 touches the inner surface of the wing 3 by being folded back. The outer edge 622E of the folded back portion 622 is located outside the absorbent core 31 in the width direction, and closes the wing 3 in the width direction in the vicinity of the outer edge 31E of the absorbent core 31 The outer side is also pressed toward the wearer side (X222). Therefore, it is possible to suppress the twisting of the wings 3 in the development process 4, thereby suppressing the problem that the wing adhesive portions 72 stick to each other or the wing adhesive portions 72 stick to an unintended area. I can.

The inner edge 63I of the first starting point portion 63 may be disposed outside the absorbent core 31 in the width direction W in the central region S3. The standing point of the entire constricted portion 62 in the central region S3 becomes the first starting point portion 63. Since the inner edge of the first starting point 63 is located outside the width direction W than the absorbent core 31, when the wing 3 tries to move inward in the width direction, it is in the first folded state. It becomes easy for the contraction part 62 to touch the inner surface of the wing 3 in this. Accordingly, the flap portion can be pressed toward the outside in the width direction, and twisting of the wing in the development step 4 can be suppressed.

Further, the inner edge 64I of the second starting point portion 64 may be disposed in a region overlapping the absorbent core 31. The second starting point portions 64 are provided in pairs at intervals in the front-rear direction, and the region between the second starting point portions 64 in the front-rear direction L is the second starting point portion 64 as a starting point. Stand up. By overlapping the second starting point portion 64 on the absorbent core 31 having relatively high rigidity, the standing point by the second starting point portion 64 is stabilized, and the second starting point portion in the anteroposterior direction (L) In the region between (64), the contraction portion 62 is more likely to stand up.

The flap fixing portion 92 may overlap the region between the pair of wing adhesive portions 72 in the thickness direction T, and may be spaced apart from the wing adhesive portion 72. In the deployment process 4, when the user pulls the packaging sheet 100, the flap release sheet 76 moves in the spreading direction away from the wing adhesion portion 72 in the thickness direction T (X162 in FIG. 16, FIG. 17 x 17). At this time, since the wing adhesive portion 72 is spaced apart from the flap fixing portion 92 in the width direction (W), it is difficult to move in the spreading direction together with the flap fixing portion 92, and it is easy to maintain a flat state. . Therefore, in the development process 4, the flap peeling sheet 76 is easily peeled from the wing adhesive portion 72, and the wing adhesive portions adhere to each other, or the wing adhesive portion 72 adheres to an unintended area. You can suppress the problem.

The leakage preventing non-joined portion 66 of the leakage preventing gather 60 may be folded back to reach the outer edge 622E of the bent portion 922 in the expanded state. The outer edge of the fold-back portion 622 is not joined to the extension portion 621 but stands with respect to the extension portion 621. The folded back portion 622 is more likely to stand outward in the width direction (W) and toward the wearer, and the wing 3 is pressed toward the outside in the width direction, and the inside of the wing 3 in the width direction (W) Can regulate movement to

The outer edge 65E of the leakage preventing joint 65 may be disposed outside the outer edge 31E of the absorbent core 31 in the width direction W. The standing point of the folded back portion 622 in the region overlapping the second starting point portion 64 becomes the outer edge 65E of the leak-proof joint 65. Since the standing point of the folded back portion 622 is located outside the width direction W than the absorbent core 31, the wing 3 in the folded back state would have tried to move inside the width direction W. At this time, the contraction portion 62 is likely to touch the inner surface of the wing. By pressing the wing 3 toward the outside in the width direction, it is possible to restrict the movement of the wing 3 to the inside in the width direction.

The leakage preventing elastic member 61 may be disposed outside the flap release sheet 76 in the width direction W in the first folded state. The area outside the flap release sheet 76 in the first folded state in the width direction W is not covered by the flap release sheet 76, and its rigidity is low and it is easily deformed. By providing the leak-preventing elastic member 61 of the folded portion 622 in the above region, it is possible to suppress the movement of the wing 3 in the width direction inward in a region having relatively low rigidity.

A low unit weight portion 34 may be provided in the central region S3. Specifically, a first low unit weight portion 341 extending at least in the front-rear direction is provided in the central region S3. The low unit weight portion 34 has a curved shape in which the center in the width direction protrudes toward the front side, and extends in the front-rear direction (L). The absorbent core 31 of the center region S3 is easily bent from the first low unit weight portion 341 as a starting point. More specifically, as shown in FIG. 22, when the wing 3 is pulled through the flap release sheet 76 and the wing adhesive portion 72, the center of the width direction W of the absorbent core 31 is flap It is deformed into a curved shape so as to be separated from the release sheet 76. As a result, as shown in FIGS. 18 and 22, the root of the wing 3 located in the region on the front edge side of the second folding line FL2 moves inward in the width direction W.

Accordingly, in the development step 4, the flap release sheet 76 moves in the development direction while the root of the wing 3 moves inward in the width direction W (X162 in FIG. 16 and X17 in FIG. 17). At this time, by pressing the wing 3 outward in the width direction by the contraction portion 62, it is easy to keep the wing adhesive portion 72 in a flat state. It is possible to suppress the occurrence of wrinkles and the like in the wing adhesive portion 72.

The low unit weight portion 34 may be overlapped with a region between the pair of wing adhesive portions 72 in the thickness direction T. The absorbent core 31 of the central region S3 is easily bent from the low unit weight portion 34 between the pair of wing adhesive portions 72. Therefore, when the wing adhesive portion 72 is pulled through the flap release sheet 76, the wing 3 is more likely to stand up. At this time, the wing 3 is urged to the outside in the width direction W by the contraction portion 62, so that it is easy to maintain the wing adhesion portion 72 in a flat state. Accordingly, the flap release sheet 76 can be moved in the spreading direction, while suppressing the occurrence of wrinkles or the like in the wing adhesive portion 72, and the flap release sheet 76 can be peeled from the wing adhesive portion 72.

The low unit weight portion 34 may be provided in a region that does not overlap with the body adhesive portion 71 and the wing adhesive portion 72 in the expanded state of the package body 110. A region that does not overlap with the body adhesive portion 71 and the wing adhesive portion 72 is a region that is not bonded to an undergarment or the like at the time of wearing and is easily deformed. By providing the low unit weight portion 34 in the above region, the absorbent core 31 is more easily deformed starting from the low unit weight portion 34, and the wing 3 is more likely to stand up. The flap release sheet 76 and the wing 3 easily fall apart in the spreading direction, and the flap release sheet 76 can be peeled from the wing adhesive portion 72 while suppressing the twist of the wing 3.

The package body of the present embodiment is configured to absorb the distortion of the absorbent article in the fourth unfolded state. Specifically, the second low unit weight region R41 may extend in the width direction W in the region on the front edge side of the flap fixing portion 92 in the deployed state. When expanding the second folding line FL2 as a starting point, depending on the user, it may be difficult to pull the packaging sheet 100 substantially perpendicular to the shear edge 1F of the absorbent article 1. When the front edge 1F of the absorbent article 1 is gripped with one hand and the packaging sheet 100 is pulled with the other hand, the flap fixing portion 92 applied by force through the packaging sheet 100 is obliquely It is pulled, and a distortion occurs in the body portion 2 in the region between the flap fixing portion 92 and the front edge 1F of the absorbent article 1. The direction in which the flap release sheet 76 and the wing adhesive part 72 are separated from each other when warping occurs in the main body 2 in the region between the flap fixing part 92 and the front edge 1F of the absorbent article 1 It becomes difficult to move. There is a fear that shear stress occurs due to the wing adhesive portion 72 and the flap peeling sheet 76 cannot be smoothly peeled from the wing adhesive portion 72.

The second low unit weight region R41 extends in the width direction W in the region on the front edge (second short edge) 1F side than the flap fixing portion 92, so that the second low unit The distortion of the main body 2 can be absorbed by the weight region R41. Specifically, as shown in FIG. 23, the second low unit weight region R41 due to the first low unit weight portion 341 is deformed, so that in the anteroposterior direction (L) and the width direction (W). It can absorb distortion. Fig. 23 is a diagram showing a state of deformation of the absorbent core 31 as viewed from a plan view of the absorbent article. Fig. 23(a) is a state before deformation, and Fig. 23(b) is a state after deformation. For example, with respect to the front edge 1F of the absorbent article, when the wing 3 is pulled to the left side and the upper side in FIG. 21 through the flap fixing portion 92 and the packaging sheet 100, the wing 3 Thus, a force is applied to the body portion 2 sandwiched between the left and upper sides. As shown in FIG. 23B, when a force is applied to the main body 2 toward the left and upper sides, the first low unit weight portion 341 is deformed. More specifically, the force of the symbol X211 is applied to the area on the left side of the main body 2, and the force of the symbol X211 is applied to the right side of the main body. Thereby, the first low unit weight portion 341 is deformed, so that the flap fixing portion 92 and the main body fixing portion 91 are inclined toward the left and upward, and the flap fixing portion 92 and the wing adhesive portion 72 Can absorb the distortion of. Fig. 24 is a perspective view of the package body 110 in the unfolding step 4, and schematically shows a state in which the distortion of the region on the front edge side of the flap fixing portion 92 is absorbed in the fourth unfolding step. Reference numeral 22WCL in FIG. 24 denotes the center of the body portion 2 in the width direction W. Even when the packaging sheet cannot be pulled substantially vertically with respect to the shear edge of the absorbent article, the second side low unit weight region R41 absorbs distortion, and the flap release sheet 76 is transferred to the wing adhesive portion 72. Can be pulled approximately vertically. Accordingly, the flap release sheet 76 can be easily removed from the wing adhesive portion 72.

The second low unit weight region R41 may extend in the width direction W in the region between the flap fixing portion 92 and the first folding line FL1 in the deployed state. In the region between the flap fixing portion 92 and the first folding line FL1, in the fourth unfolding step, the force in the unfolding direction is more likely to be applied. Since the second side low unit weight region R41 is provided in the region between the flap fixing portion and the first folding line FL1, the effect of absorbing the distortion of the main body 2 is more easily obtained.

The second side low unit weight region R41 may reach the outer edge of the absorbent core 31. The area on the front edge 1F side of the absorbent article 1 and the area overlapping with the flap fixing portion 92 can be divided by the second side low unit weight area R41, It is easier to obtain the effect of absorbing distortion.

The body fixing portion 91 may have a first body fixing portion 911. The 1st body fixing part 911 is provided in the 1st area|region R11, and is arrange|positioned at the 1st end edge side rather than the 1st folding line FL1. Since the packaging sheet 100 and the main body release sheet 75 are joined at the first main body fixing portion 911 on the rear edge side of the first fold line, the second fold line FL2 is formed in the unfolding step 4. When the packaging sheet 100 is pulled to develop from the starting point, the absorbent article becomes more easily unfolded through the packaging sheet 100 and the body release sheet 75. When moving the package body 110 in the rotation direction X14 of FIG. 14, the first main body fixing part 911 is located outside the moving direction with respect to the moving area (area behind the second folding line). . Accordingly, it is easy to apply a force to the entire area to be moved, and the package body 110 can be more smoothly moved in the rotation direction X14, and the package body 110 can be unfolded from the second fold line.

The body fixing part 91 has a first body fixing part 911, and the low unit weight part 34 is located in the second region R12 (a region between the first fold line and the second fold line). You may have a medium low unit weight region R44. The force applied to the packaging sheet 100 is transmitted to the body release sheet 75 through the body fixing portion 91. The main body release sheet 75 is in contact with the main body adhesive portion 71, and it is easy to transmit a force to the absorbent article 1. Therefore, when the user exerts a force on the first fold line FL1 through the packaging sheet 100 in the third folded state, the force is applied to the main body release sheet 75 through the main body fixing portion 91. The first fold line side of the main body 2 tends to move in the rotational directions X162 and X17 (FIGS. 16 and 17) centering on the second fold line FL2. In the third folded state, when the first folding line side of the main body 2 moves in the rotational direction around the second folding line FL2, the absorbent core 31 of the second region R12 has an intermediate low unit weight. The region R44 is transformed as a starting point. As the absorbent core 31 of the second region R12 is deformed, the flap release sheet 76 is deformed following the absorbent core 31 of the second region R12, and the flap release sheet 76 is wing adhesion. It is deformed to be spaced apart from the portion 72. Accordingly, the flap release sheet 76 can be easily removed from the wing adhesive portion 72. The medium low unit weight region R44 may be configured so that the absorbent core 31 of the second region R12 is easily deformed, may extend in the width direction, or may extend in the front-rear direction. More preferably, as in the present embodiment, the intermediate low unit weight region R44 may extend in the width direction, and may also extend in the front-rear direction. That is, the intermediate low unit weight region R44 may be inclined with respect to the width direction and may also be inclined with respect to the front-rear direction. According to this configuration, the absorbent core of the second region R12 is easily bent both in the front-rear direction and in the width direction, and the flap release sheet 76 is more easily deformed so as to be spaced apart from the wing adhesion portion 72.

The main body fixing part 91 may have a first body fixing part 911 and a second body fixing part 912. The second body fixing portion 912 is disposed in the second region R12 between the first folding line FL1 and the second folding line FL2 in the unfolded state of the package. In both the first region R11 and the second region R12, the packaging sheet 100 and the body release sheet 75 are joined by a body fixing portion 91. When the packaging sheet 100 is pulled so as to develop from the second fold line FL2 as a starting point, force can be applied to both sides of the first fold line FL1 interposed therebetween, so that the packaging sheet 100 and the body release sheet Through (75), the absorbent article becomes easier to deploy.

The first body fixing portion 911 and the second body fixing portion 912 may overlap in the thickness direction T in the third folded state. At least a portion of the first body fixing portion 911 and at least a portion of the second body fixing portion 912 may overlap each other. In the unfolding process 4, when a force is applied to both sides between the first folding line by the first body fixing portion 911 and the second body fixing portion 912, the force is easily transmitted, and the packaging sheet And the absorbent article is more easily developed through the body release sheet.

The boundary between the high unit weight portion 33 and the middle portion weight portion 35 may extend in the width direction W to the front edge 1F side of the absorbent article 1 from the third folding line FL3. The boundary between the high unit weight portion 33 and the middle weight portion 35 is at the outer edge in the width direction of the high unit weight portion 33 and the unit edge in the front-rear direction (L) of the high unit weight portion 33 There is. Among these, the boundary between the high unit weight portion 33 and the middle portion weight portion 35 positioned on the front side may extend in the width direction W in front of the third folding line FL3. The boundary between the high unit weight portion 33 and the middle portion weight portion 35 causes a difference in rigidity according to the unit weight difference of the absorbent material, and is easily deformed. Due to the boundary between the high unit weight portion 33 and the middle portion weight portion 35, the body portion 2 in the development step 4 can absorb distortion. The area on the front side of the third folding line FL3 is close to a portion of the package body, such as the tag tape 102, that is held by one hand. Accordingly, distortion of the main body 2 can be absorbed in a region close to the portion that holds the package 110. Even when the packaging sheet 100 cannot be pulled substantially vertically with respect to the shear edge of the absorbent article, the boundary between the high unit weight portion 33 and the middle portion weight portion 35 absorbs distortion, and the flap release sheet 76 ) Can be pulled approximately vertically with respect to the wing adhesive portion 72. Accordingly, the flap release sheet 76 can be easily removed from the wing adhesive portion 72.

In order to further obtain the effect of absorbing the distortion caused by the boundary between the high unit weight portion 33 and the middle portion weight portion 35, the front side of the boundary between the high unit weight portion 33 and the middle portion weight portion 35, A low unit weight portion 34 extending in the width direction W may be provided. The distortion of the main body 2 can be absorbed by the difference in rigidity due to the boundary between the high unit weight portion 33 and the middle weight portion 35 and the deformation of the low unit weight portion.

In addition, in order to further obtain the effect of absorbing distortion caused by the boundary between the high unit weight portion 33 and the middle portion weight portion 35, the front side of the boundary between the high unit weight portion 33 and the middle portion weight portion 35 In addition, a non-adhesive portion in which the adhesive portion 70 is not provided may be provided to extend in the width direction. The non-adhesive portion is a region that is not bonded to the underwear or the like at the time of wearing and is easily deformed. By providing the non-adhesive portion extending in the width direction W, the area overlapping the non-adhesive portion of the main body 2 is deformed, and the distortion of the main body 2 can be absorbed. The non-adhesive portion extending in the width direction may be a region between the adhesive portions in the front-rear direction in the form in which the adhesive portions extending in the width direction are arranged at intervals in the front-rear direction.

At least one of the boundary between the high unit weight portion 33 and the middle portion weight portion 35, the low unit weight portion 34 extending in the width direction, and the non-adhesive portion may be provided, or a combination thereof may be provided. In addition, the boundary between the high unit weight portion 33 and the middle portion weight portion 35, the low unit weight portion 34 extending in the width direction, and the non-adhesive portion may reach the outer edge of the absorbent core 31. It is not necessary to reach the outer edge of the absorbent core 31.
