Description

TECHNICAL FIELD The present invention relates to an absorbent article package in which absorbent articles are individually wrapped by a packaging sheet.

Patent Literature 1 discloses a package for absorbent articles in which absorbent articles are individually wrapped with a packaging sheet. The absorbent article of Patent Literature 1 has a body portion and a flap portion extending outward in the width direction from the body portion. The package of the absorbent article includes a flap release sheet covering the flap adhesive part with the flap part folded on the skin facing side of the main body, a main body release sheet covering the main body adhesive part, and a non-skin of the main body release sheet. and a packaging sheet located on the opposite surface side and enclosing the absorbent article.

In the absorbent article package of Patent Document 1, the flap portion is folded toward the skin-facing side of the body portion, and is folded along the first fold extending in the width direction as a base point, and is also folded around the first fold as a base point. In this folded state, the second fold extending in the width direction and located on the front side of the first fold is folded as a base point. In the region where the packaging sheet and the flap release sheet face each other in a state where the packaging sheet is folded about the second crease, the packaging sheet and the flap release sheet are joined via the flap fixing portion.

The absorbent article package is folded around the second fold, and is folded around the third fold, which extends in the width direction and is located on the front side of the second fold. The front edge of the packaging sheet is attached to the non-skin-facing side of the area between the first and second folds of the packaging sheet with a tag tape in a state where the packaging sheet is folded about the third fold.

When unfolding the absorbent article package of Patent Document 1, the grip portion of the tag tape is picked to unfold the front portion of the absorbent article, and then the front end portion of the absorbent article is picked and pulled in the unfolding direction.

Japanese Unexamined Patent Application Publication No. 2011-45608

For the absorbent article package, the package sheet is pulled in the deployment direction through the vicinity of the front end of the package such as the tag tape, and the flap release sheet is pulled together with the package sheet while the absorbent article is deployed. However, since the flap release sheet is in contact with the flap adhesive portion, the flap portion easily deforms so as to follow the flap release sheet via the flap adhesive portion. When the flap part follows the flap release sheet, the tip of the flap part rises with respect to the base of the flap part. In this state, when the flap release sheet is pulled together with the packaging sheet, shear stress is generated by the flap adhesive portion when the flap release sheet slides in the width direction with respect to the flap portion. Therefore, it was sometimes difficult to peel the flap release sheet from the flap adhesive portion.

Therefore, there is a demand for a package of absorbent articles in which the absorbent articles are individually wrapped by a packaging sheet, and in which the flap release sheet can be easily peeled off from the adhesive flap portion.

A package of absorbent articles is a package of absorbent articles in which absorbent articles are individually wrapped by a packaging sheet. The absorbent article includes a main body portion having an absorbent core, a pair of flap portions extending outward on both sides in the width direction of the main body portion, and arranged on the non-skin facing side of the main body portion. a pair of flap adhesive portions having an adhesive that attaches to the underwear, a pair of flap adhesive portions that are arranged on the non-skin facing side of each flap portion and have an adhesive that attaches the body portion to the underwear, and the flap portion a flap release sheet that covers the pair of flap adhesive portions in a folded state on the side of the body facing the skin. The package body is in a first folded state in which the flap portion is folded toward the skin facing side of the main body portion, and a first edge, which is an outer edge in the front-rear direction of the package body, extends in the width direction. In a second folded state in which it is folded inside the package with the crease as a base point and is folded with the first crease as a base point, it extends in the width direction and is on the side of the second edge opposite to the first edge. It is folded inside the package with the located second crease as a base point. At least a part of the flap adhesive portion and the flap release sheet is arranged closer to the second edge than the second fold line. It has a flap fixing portion that joins the packaging sheet and the flap release sheet in a region where the packaging sheet and the flap release sheet face each other in a third folded state folded around the second fold line. The absorbent core has a low basis weight portion in which the basis weight of the absorbent core is lower than that of the surrounding area.

(1) Overview of Embodiments At least the following matters will become clear from the description of this specification and the accompanying drawings.
A package for absorbent articles according to one aspect is a package for absorbent articles in which absorbent articles are individually wrapped by a packaging sheet. The absorbent article includes a main body portion having an absorbent core, a pair of flap portions extending outward on both sides in the width direction of the main body portion, and arranged on the non-skin facing side of the main body portion. a pair of flap adhesive portions having an adhesive that attaches to the underwear, a pair of flap adhesive portions that are arranged on the non-skin facing side of each flap portion and have an adhesive that attaches the body portion to the underwear, and the flap portion a flap release sheet that covers the pair of flap adhesive portions in a folded state on the side of the body facing the skin. The package body is in a first folded state in which the flap portion is folded toward the skin facing side of the main body portion, and a first edge, which is an outer edge in the front-rear direction of the package body, extends in the width direction. In a second folded state in which it is folded inside the package with the crease as a base point and is folded with the first crease as a base point, it extends in the width direction and is on the side of the second edge opposite to the first edge. It is folded inside the package with the located second crease as a base point. At least a part of the flap adhesive portion and the flap release sheet is arranged closer to the second edge than the second fold line. It has a flap fixing portion that joins the packaging sheet and the flap release sheet in a region where the packaging sheet and the flap release sheet face each other in a third folded state folded around the second fold line. The absorbent core has a low basis weight portion in which the basis weight of the absorbent core is lower than that of the surrounding area. The low basis weight portion has a second side low basis weight area extending in the front-rear direction on the second edge side of the second crease.

According to this aspect, when a force is applied to the first crease through the packaging sheet when unfolding the package with the second crease as a base point, the package is folded around the second crease. The region closer to the first fold than the second fold moves in the rotational direction with respect to the region closer to the second edge than the second fold, and along with this movement, the flap release sheet moves in the rotational direction together with the packaging sheet. At this time, the area on the second edge side of the second crease line is easily bent in the width direction due to the deformation base point extending in the front-rear direction by the second side low-basis area. Therefore, when the flap portion is pulled through the flap release sheet and the flap adhesive portion, the root portion of the flap portion moves inward in the width direction. The flap peeling sheet is pulled in the unfolding direction together with the packaging sheet, and tries to maintain a flat state. On the other hand, as the root portion of the flap portion moves inward in the width direction, the angle at which the flap portion rises from the skin-facing surface side of the absorbent article increases. Therefore, the flap release sheet and the flap portion can be easily separated in the unfolding direction, the outer edge of the flap adhesive portion can be separated from the flap release sheet, and the flap release sheet can be easily separated from the flap adhesive portion.

According to a preferred aspect, the low basis weight portion has front and rear low basis weight areas parallel to the front-rear direction, and the front and rear low basis weight areas are areas closer to the first edge than the first crease in the unfolded state. may not be set to

According to this aspect, when unfolding from the second fold as a base point, the region closer to the first fold than the second fold is moved in the rotational direction with respect to the region closer to the second edge than the second fold. At this time, the area between the first fold line and the flap fixing portion is less likely to deform inward in the width direction, and the area closer to the second edge than the second fold line is more likely to deform inward in the width direction. Therefore, when the flap portion is pulled through the flap release sheet and the flap adhesive portion, the root portion of the flap portion moves inward in the width direction, and the rising angle of the flap portion tends to increase.

According to a preferred aspect, the front and rear low eyes area is not provided in the area between the first fold line and the second fold line in the unfolded state.

According to this aspect, when unfolding from the second crease, the region closer to the first edge than the second crease is less likely to deform, and the region closer to the second edge than the second crease is relatively wider in the width direction. It becomes easy to deform inside. Therefore, when the flap portion is pulled through the flap release sheet and the flap adhesive portion, the root portion of the flap portion moves inward in the width direction, and the rising angle of the flap portion tends to increase.

According to a preferred aspect, in the third folded state, the second side low mesh area and the flap fixing portion are positioned closer to the first fold line than the centers of the second fold line and the first fold in the front-rear direction. may be placed.

According to this aspect, the flap release sheet can be removed by pulling the packaging sheet at the time of unfolding, because the flap fixing portion is separated from the second fold that serves as a rotation axis when unfolding from the second crease. It becomes easier to move in the deployment direction. At this time, since the base point of deformation by the second side low basis area is provided on the side of the first crease, the rising angle of the flap portion can be increased on the side of the first crease.

According to a preferred aspect, the low basis weight part has a first side low basis weight area arranged closer to the first edge than the first crease in the unfolded state, and the first side low basis weight area is unfolded. It may extend outward in the width direction toward the first fold line in a region between the first fold line and the flap fixing portion.

According to this aspect, the deformation reference point extending outward in the width direction toward the first fold is formed in the region between the first fold and the flap fixing portion. In a cross-sectional view in the thickness direction, the absorbent core closer to the flap release sheet than the flap fixing portion is deformed to extend outward in the width direction from the flap fixing portion toward the first fold line due to the deformation base point of the first side low basis weight region. A base point is formed. Therefore, when the flap release sheet is pulled by the packaging sheet, the flap release sheet also forms a deformation base point extending outward in the width direction from the flap fixing portion toward the first fold line. The flap release sheet is deformed so as to be separated from the flap adhesive portion, and the flap release sheet can be easily separated from the flap adhesive portion.

According to a preferred aspect, the main body adhesive part is covered with a main body release sheet that is joined to the packaging sheet via the main body fixing part, and the main body fixing part is closer to the first fold line than the first fold line in the unfolded state. Arranged in a region on one edge side, the low-basis weight portion may have an intermediate low-basis weight region positioned between the first fold line and the second fold line in the unfolded state.

According to this aspect, the force applied to the packaging sheet is transmitted to the main body release sheet via the main body fixing portion. The body release sheet is in contact with the body adhesive portion of the absorbent article, and easily transfers force to the absorbent article. Therefore, in the third folded state, when the user applies force to the first fold through the packaging sheet, the force is transmitted to the main body release sheet through the main body fixing portion, and the main body is folded around the second fold. The first fold side of the part is likely to move in the direction of rotation. When the first fold side of the main body portion moves in the rotational direction around the second fold line from the third folded state, the absorbent core in the region between the first fold line and the second fold line is deformed with the intermediate low mesh area as the base point. do. By deforming the absorbent core in the region between the first fold and the second fold, the flap release sheet is deformed away from the flap adhesive portion, and the flap release sheet can be easily peeled off from the flap adhesive portion. can.

According to a preferred aspect, the second side low basis weight region may extend in the width direction in a region closer to the second edge than the flap fixing portion in the unfolded state.

According to this aspect, since the second side low basis weight area extends in the width direction in the area closer to the second edge than the flap fixing portion, twisting can be absorbed by the second side low basis weight area. Even if the packaging sheet cannot be pulled substantially perpendicularly to the second edge of the absorbent article, the second side low basis weight area absorbs the twist and pulls the flap release sheet against the flap adhesive part. It can be pulled vertically. Therefore, the flap release sheet can be easily released from the flap adhesive portion.

According to a preferred aspect, the second side low basis weight area may extend in the width direction in the area between the flap fixing portion and the first fold in the unfolded state.

According to this aspect, in the fourth unfolding step, the force in the unfolding direction is more likely to be applied to the region between the flap fixing portion and the first fold line. By providing the second side low basis weight area in the area between the flap fixing portion and the first fold in the unfolded state, it is easier to obtain the effect of absorbing the twist of the main body.

According to a preferred aspect, the second side low basis weight area may reach the outer edge of the absorbent core.

According to this aspect, the region on the second edge side of the absorbent article and the region overlapping the flap fixing portion can be divided by the second side low basis weight region, and the effect of absorbing the twist of the body portion can be more easily obtained. .

Similarly, the bonding strength between the packaging sheet 100 and the flap release sheet 76 by the flap fixing portion 92 is higher than the bonding strength between the flap release sheet 76 and the absorbent article 1 by the wing adhesive portion 72 . Therefore, when the flap release sheet 76 is pulled through the packaging sheet during use, the flap release sheet 76 separates from the absorbent article and the main body adhesive portion 71 without being separated from the packaging sheet 100 and the flap release sheet 76. .

Also, the bonding strength between the tag tape 102 and the packaging sheet 100 may be higher than the strength of the body fixing portion 91 that bonds the packaging sheet 100 and the body release sheet 75 . Therefore, the package 110 can be unfolded while holding the tag tape 102 without damaging the body fixing portion 91 that joins the package sheet 100 and the body release sheet 75 .

The bonding strength between the tag tape 102 and the packaging sheet 100 may be higher than the bonding strength between the body release sheet 75 and the body adhesive portion 71 . Also, the bonding strength between the tag tape 102 and the packaging sheet 100 may be higher than the bonding strength between the flap release sheet 76 and the wing adhesive portion 72 . As will be described later, according to the package of this embodiment, the user holds the package 110 in the vicinity of the tag tape 102 and the vicinity of the front edge of the absorbent article 1 and begins to unfold the absorbent article 1, and continues until the unfolding is completed. The packaging sheet 100 and the absorbent article can be separated without picking up. At this time, since the bonding strength between the tag tape 102 and the packaging sheet 100 is higher than the bonding strength between the main body release sheet 75 and the main body adhesive portion 71, the packaging sheet 100 can be removed while maintaining the bonding between the tag tape 102 and the packaging sheet 100. The main body adhesive part 71 and the main body release sheet 75 can be separated from each other. Similarly, since the bonding strength between the tag tape 102 and the packaging sheet 100 is higher than the bonding strength between the flap release sheet 76 and the wing adhesive portion 72, the bonding between the tag tape 102 and the packaging sheet 100 is maintained while the packaging sheet 100 is removed. The wing adhesive part 72 and the flap peeling sheet 76 can be peeled off via the wing adhesive part 72 .

Next, with reference to FIGS. 11 to 20, the unfolding mode of the package during use will be described. FIG. 11 is a perspective view of a packaged state in which the absorbent article 1 is individually wrapped by the packaging sheet 100. FIG. 12 is a cross-sectional view taken along line 11A-11A shown in FIG. 11.

As shown in FIG. FIG. 16 shows the package 110 in deployment steps 6 and 7. FIG. FIG. 17 shows the package 110 in the unfolding step 7. As shown in FIG. 18A and 18B are diagrams showing the package 110 in the expansion step 4. FIG. 19 is a cross-sectional view taken along line 13A-13A of FIG. 13. FIG. FIGS. 20 to 22 are diagrams showing the package in the expansion step 4 in a cross section taken along the line 13A-13A shown in FIG. 13. FIG. 19 and 20 omit the leak-proof gathers, and the leak-proof gathers 60 are shown in FIGS. 21 and 22 for convenience of explanation. Note that the deployment mode shown below is an example, and may be deployed in different modes depending on the user.

First, the user grips the tag tape 102 and unfolds the absorbent article 1 and the packaging sheet 100 from the third fold line FL3 in order to unfold the package 110 from the packaging state shown in FIGS. 11 and 12 . (Development step 1). FIG. 13 shows the package 110 in the third folded state, which is folded around the first fold line FL1 and the second fold line FL2 and is not folded by the third fold line FL3.

The user then peels off the packaging sheet 100 from the main body adhesive portion 71 (unfolding step 2). More specifically, as shown in FIG. 13, the front edge 100F of the packaging sheet 100 is moved in the rotation direction X131 around the second fold line FL2 to move the packaging sheet 100 away from the main adhesive portion 71. As shown in FIG. At this time, since the body release sheet 75 is joined to the packaging sheet 100 by the body fixing portion 91 , it moves together with the packaging sheet 100 . In FIG. 13, the packaging sheet 100 and the main release sheet 75 in the development step 2 are indicated by a dashed line.

After peeling off the packaging sheet 100 from the main adhesive portion 71 to the vicinity of the second fold FL2, the user moves the packaging sheet 100 in the rotation direction X132 around the first fold FL1, and moves the packaging sheet 100 to the main adhesive portion 71. (deployment step 3). In FIG. 13, the packaging sheet 100 and the main release sheet 75 in the development step 3 are indicated by solid lines.

As shown in FIG. 14, the user then unfolds the packaging sheet 100 and the absorbent article 1 from the second fold line FL2 (unfolding step 4). In unfolding step 4, the package 110 is unfolded from the third folded state to the second folded state. The packaging sheet 100 and the flap release sheet 76 are joined via the flap fixing portion 92 in the third folded state in which the second fold line FL2 is the base point. Therefore, when the package 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 via the packaging sheet 100 . More specifically, the user moves the packaging sheet 100 in the rotation direction X14 around the second fold line FL2. 14, the packaging sheet 100, the body portion 2, and the flap release sheet 76 move in the rotation direction X14, and the flap release sheet 76 moves away from the wing adhesive portion 72. As shown in FIG. FIG. 14 shows a state in which the flap release sheet moves in the rotational direction together with the packaging sheet, and the flap release sheet is separated from the wing adhesive portion 72 .

The user further pulls the packaging sheet 100 so that the packaging sheet 100 and the absorbent article 1 are unfolded from the second fold line FL2 (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 other members are not folded at the second fold line FL2, which is the first folded state. In this state, the flap release sheet 76 is in contact with the hip flap adhesive portion 73 located in the second region R12. Although the hip flap adhesive portion 73 does not appear in the cross section shown in FIG. 15, the position corresponding to the hip flap adhesive portion 73 is virtually shown.

Then, as shown in FIG. 16, the user moves the packaging sheet 100 in the rotation direction X161 with the first fold line FL1 as a base point (unfolding step 6). At this time, the main release sheet 75 and the flap release sheet 76, which are arranged with the packaging sheet 100 interposed therebetween, move in the rotation direction X161 with the first folding line FL1 as a base point. The body release sheet 75 is peeled off from the body adhesive portion 71 in the first region R11. At this time, the flap release sheet 76 positioned closer to the trailing edge than the second fold line FL2 is in contact with the hip flap adhesive portion 73 in the second region R12. Therefore, when the user further pulls the packaging sheet 100, the package 110 moves in the rotation direction X162 (FIG. 16) and the rotation direction X17 (FIG. 17) with the first fold line FL1 as the base point (unfolding step 7). FIG. 17 shows a state in which the regions of the packaging sheet 100 and the absorbent article 1 on the trailing edge side of the first fold line FL1 are moving in the rotation direction X17 with the first fold line FL1 as the base point. The user can peel off the body release sheet 75 and the flap release sheet 76 together with the packaging sheet 100 to expose the body adhesive portion 71 , the wing adhesive portion 72 and the hip flap adhesive portion 73 . According to such an unfolding method, the user starts unfolding by holding the package 110 near the tag tape 102 and near the front edge of the absorbent article 1, and wraps the absorbent article 1 without lifting the hand until the unfolding is completed. The sheet 100 and the absorbent article can be separated.

In the unfolding step 4 described above, depending on the user, the packaging sheet 100 and the absorbent article 1 are gripped in the vicinity of the first fold line FL1, and the package body in the vicinity of the first fold line FL1 is moved in the rotational direction with the second fold line FL2 as a base point. can do. When unfolded in this manner, the unfolding force of the packaging sheet 100 is easily transmitted to the flap fixing portion 92 , and the flap release sheet 76 can be easily peeled off from the wing adhesive portion 72 .

However, depending on the user, the front edge 100F side of the packaging sheet 100 is gripped and the packaging sheet 100 is pulled and unfolded, as in the unfolding step 4 described above, following the unfolding step 3 preceding it. Specifically, for example, the front edge 1F of the absorbent article 1 is gripped with one hand, the front edge 100F of the packaging sheet 100 is gripped with the other hand, and the first fold FL1 and the front edge of the absorbent article 1 are folded. In the region between the edges 1F, the packaging sheet 100 is peeled off from the main body adhesive part 71 (unfolding step 3), the packaging sheet 100 and the absorbent article 1 are grasped as they are, and the packaging sheet 100 is interposed with the first fold line FL1. force is applied to unfold the package 110 (unfolding step 4). In the absorbent article package 110 according to the present embodiment, the package sheet 100 is gripped in the deployment step 4, and when the package 110 is deployed, the body release sheet 75 is removed from the body adhesive portion 71. It is configured so that it can be easily peeled off and the flap release sheet 76 can be easily peeled off from the wing adhesive portion 72 .

As described above, in unfolding step 4, when a force is applied to the first fold line FL1 through the packaging sheet 100, the package body 110 rotates around the second fold line FL2 in the direction of rotation of the first fold line FL1 side. X14 (FIG. 14), along with the movement, the flap release sheet 76 moves in the rotation direction X14 together with the packaging sheet 100, and the flap release sheet 76 separates from the wing adhesive portion 72 in the third region R13.

When moving the first fold FL1 side in the rotation direction X14 about the second fold FL2 side, it is necessary to move not only the packaging sheet 100 but also the entire absorbent article 1 in the rotation direction. If the absorbent article 1 does not move in the rotation direction X14 even if a force is applied only to the packaging sheet 100, a force is applied to move only the packaging sheet 100 in the front-rear direction L. cannot be pulled 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 release sheet 76, which may make it difficult for the flap release sheet 76 to separate from the wing adhesive portion 72 in the third region R13.

In the packaging body 110 according to the present embodiment, the force applied to the packaging sheet 100 is transmitted to the body release sheet 75 via the body fixing portion 91 . This is because the main body release sheet 75 is in contact with the main body adhesive part 71 and easily transmits force to the absorbent article 1 . When the user applies force through the packaging sheet 100 toward the first fold line FL1 side in the rotation direction X14, the force is transmitted to the main body release sheet 75 through the main body fixing portion 91, and the first fold line FL1 side of the absorbent article 1 is applied. The fold FL1 side tends to move in the rotation direction X14.

The body fixing portion 91 overlaps the flap fixing portion 92 in the thickness direction T. As shown in FIG. Therefore, force is transmitted from the packaging sheet 100 to the main body release sheet 75 and the absorbent article 1 via the main body fixing portion 91, and when the packaging sheet 100 and the main body release sheet 75 move in the rotation direction X14, the flap release sheet 76 can be easily moved in the rotation direction X14, and the flap peeling sheet 76 can be easily peeled off from the wing adhesive portion 72. As shown in FIG. Therefore, the body release sheet 75 can be easily peeled off from the body adhesive portion 71 and the flap release sheet 76 can be easily peeled off from the wing adhesive portion 72 .

The main body fixing portion 91 and the flap fixing portion 92 are arranged in the front-rear direction L between the second fold FL2 and the first fold FL1 in the third folded state in which the package 110 is folded around the first fold FL1 and the second fold FL2. It may be arranged on the first fold FL1 side of the center. The center of the front-rear direction L of the second fold FL2 and the first fold FL1 is the center of the third region R13 in the front-rear direction. Since the main body fixing portion 91 and the flap fixing portion 92 are separated from the second fold line FL2, which is the rotation axis in the unfolding step 4, the first fold line FL1 side is rotated in the rotational direction around the second fold line FL2 in the unfolding step 4. easier to move. At least a portion of the main body fixing portion 91 and at least a portion of the flap fixing portion 92 may be arranged closer to the first fold FL1 than the center of the second fold FL2 and the first fold FL1 in the front-rear direction L. . More preferably, the main body fixing portion 91 and the flap fixing portion 92 are biased toward the first fold line FL1 from the center of the front-rear direction L of the second fold line FL2 and the first fold line FL1.

The flap fixing portion 92 overlaps the region between the pair of wing adhesive portions 72 in the thickness direction T in the third folded state in which the packaging body 110 is folded with the first folding line FL1 and the second folding line FL2 as base points. good. When the flap release sheet 76 moves away from the wing adhesive portion 72 in the unfolding step 4, the region of the flap release sheet 76 in contact with the flap fixing portion 92 moves first, and the wing adhesive portion 72 of the flap release sheet 76 moves first. The contact area follows and moves. This is because the wing adhesive portion 72 and the flap fixing portion 92 do not overlap. As shown in FIGS. 18 and 20, the tip of each wing 3 moves in the rotation direction X18 with the root of each wing as a base point, and rises from the skin facing surface side T1 of the absorbent article 1. As shown in FIGS. A pair of wings 3 and main body 2 are arranged to surround a substantially triangular space.

When the wings 3 and the body portion 2 are arranged to form a triangle, the center of the flap release sheet 76 in the width direction W (the portion overlapping the flap fixing portion 92) is pulled toward the packaging sheet 100, and the flap release sheet 76 is curved. However, the flap peeling sheet 76 tries to maintain its flat state by being pulled together with the packaging sheet 100 . Therefore, in unfolding step 4, the flap release sheet 76 moves in a state in which the tips of the wings 3 are deformed so as to stand up from the base of the wing. begin to peel off from 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 in the width direction W of the flap fixing portion 92 may be shorter than the length in the width direction W of the main body fixing portion 91 . When the tip of each wing 3 is deformed to stand up against the base of the wing 3 in the deployment step 4, the tip of each wing is pulled toward the center of the main body 2 in the width direction W to increase the angle at which the wing 3 rises. can do. Therefore, the flap peeling sheet 76 can be peeled off from the wing adhesive portion 72 more easily.

In another embodiment, the length in the width direction W of the flap fixing portion 92 may be longer than the length in the width direction W of the main body fixing portion 91 . In the unfolding step 4, the flap release sheet 76 can be pulled in the unfolding direction over a wide range in the width direction via the flap fixing portion 92 . Therefore, the flap peeling sheet 76 can be peeled off from the wing adhesive portion 72 .

The flap fixing portion 92 may be arranged to be spaced apart from the wing adhesive portion 72 in the width direction in the region between the pair of wing adhesive portions 72 . When the tip of each wing 3 is deformed so as to stand up relative to the base of the wing 3 in the deployment step 4, the rising angle of the wing 3 can be increased. Therefore, the flap peeling sheet 76 can be peeled off from the wing adhesive portion 72 more easily.

The front edge of the first wing adhesive portion 721 may be arranged on the rear side of the front edge of the second wing adhesive portion 722 . The front edge, which is the edge on the second edge side of the wing adhesive portion 72, is the side away from the second fold line FL2, which is the deployment base point in the deployment step 4. As shown in FIG. The second wing adhesive portion 722 located on the root side of the wing 3 extends further away from the second fold FL2 than the first wing adhesive portion 721 located on the tip side of the wing 3 . In the first folded state in which the wings 3 are folded toward the skin-facing side of the main body 2, the length of the wing adhesive portion located on the inner side in the width direction is short in the front-rear direction. Therefore, when the tip of each wing 3 is deformed so as to rise relative to the base of each wing 3, the tip side of the wing 3 tends to rise earlier than the base side of the wing 3. By increasing the rising angle of the wings 3, the outer edge of the wing adhesive portion 72 and the flap release sheet 76 are gradually peeled off, and the flap release sheet 76 can be peeled off from the wing adhesive portion 72 more easily.

In addition, the second low-basis area R41 of the low-basis area 34 may extend in the front-rear direction L on the front edge side of the second fold line FL2. The absorbent core 31 in the area on the front edge side of the second fold line FL2 forms a deformation base point extending in the front-rear direction L by the second side low-basis area R41, so that the absorbent core 31 can easily bend in the width direction W. Therefore, in unfolding step 4, when the wing 3 is pulled via the flap release sheet 76 and the wing adhesive portion 72, the center in the width direction W of the area on the front edge side of the second fold line FL2 is positioned from the flap release sheet 76. Deform to separate. The absorbent core 31 in the area closer to the front edge than the second fold line FL2 is deformed into a curved shape. As a result, as shown in FIG. 18, the base of the wing 3 located in the region on the front edge side of the second fold FL2 moves inward in the width direction W, and the rising angle of the wing 3 increases. Therefore, the tip of each wing rises from the base of each wing, and the pair of wings 3 and main body 2 surrounds a substantially triangular space. As described above, the outer edge of the adhesive wing portion 72 in the first folded state 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 .

Also, the front and rear low-basis area R42 of the low-basis portion 34 may not be provided in the first area R11 on the rear edge side of the first fold line FL1 in the unfolded state. In the unfolding step 4, when unfolding with the second fold FL2 as a base point, the area closer to the first fold FL1 than the second fold FL2 is moved in the rotational direction with respect to the area closer to the front edge than the second fold FL2. . At this time, since the region between the first fold FL1 and the flap fixing portion 92 is less likely to deform inward in the width direction, the region closer to the front edge than the second fold FL2 is relatively likely to deform inward in the width direction. Become. Therefore, when the wing 3 is pulled through the flap release sheet 76 and the wing adhesive portion 72, the base of the wing moves inward in the width direction W, and the rising angle of the wing 3 tends to increase. Therefore, the flap release sheet 76 can be easily separated from the wing adhesive portion 72 .

In another embodiment, the front and rear low eye weight regions R42 may not be provided in the second region R12 as well. Since the front and rear low basis weight regions R42 are not provided in both the first region R11 and the second region R12, in the unfolding step 4, the region on the first edge side of the second fold line FL2 is more difficult to deform, and the relative In general, the area closer to the front edge than the second fold line FL2 tends to deform inward in the width direction W. Therefore, the rising angle of the wings 3 is increased, and the flap release sheet 76 can be easily separated from the wing adhesive portion 72 .

The second side low basis area R41 and the flap fixing portion 92 are arranged in front of and behind the second fold line FL2 and the first fold line FL1 in the third folded state in which the package 110 is folded with the first fold line FL1 and the second fold line FL2 as base points. It may be arranged closer to the first fold line FL1 than the center in the direction L. The flap release sheet 76 is unfolded by pulling the packaging sheet 100 at the time of unfolding because the flap fixing portion 92 is separated from the second fold FL2, which serves as a rotation axis when unfolding with the second fold FL2 as a base point. Makes it easier to move in any direction. At this time, since the base point of deformation by the second side low basis area R41 is provided on the side of the first fold FL1, the rising angle of the wing 3 can be made larger on the side of the first fold FL1.

The first side low eye area R43 of the low eye area 34 may extend outward in the width direction W toward the first fold FL1 in the area between the first fold FL1 and the flap fixing portion 92 in the unfolded state. A deformation base point extending outward in the width direction W toward the first fold FL1 side is formed in a region between the first fold FL1 and the flap fixing portion 92 . In a cross-sectional view in the thickness direction, the absorbent core 31 closer to the flap release sheet than the flap fixing portion 92 moves in the width direction from the flap fixing portion 92 toward the first fold line FL1 due to the deformation base point of the first side low basis weight region R43. A deformation origin extending outside W is formed. Therefore, when the flap release sheet 76 is pulled through the packaging sheet 100 in the deployment step 4, the flap release sheet 76 also has a deformation base point extending outward in the width direction W from the flap fixing portion 92 toward the first fold line FL1. is formed. The flap release sheet 76 is deformed so as to be separated from the wing adhesive portion 72 , and the flap release sheet 76 can be easily separated from the wing adhesive portion 72 .

The packaging body of the present embodiment is configured so as to suppress unintentional adhesion of the wing adhesive portion 72 as the flap adhesive portion in the fourth unfolded state. Specifically, the outer edge 622E of the folded portion 622 may be arranged outside the absorbent core 31 in the width direction. The folded-back portion 622 of the contracted portion 62 has the leak-proof elastic member 61, and rises outward in the width direction and toward the wearer from the inner edge of the extension portion 621 in the central region S3.

As shown in FIG. 21, when the wing 3 is folded back at the flap fold line FL5, the leakproof gathers 60 are arranged between the wing 3 and the main body 2, which are arranged with the flap fold line FL5 interposed therebetween. there is Therefore, the inner surface of the wing 3 in the folded state (the side facing the skin in the unfolded state) is arranged to face the outer edge 622E of the folded portion 622 . As shown in FIG. 22 , in the unfolding step 4, when the wing 3 is pulled together with the flap release sheet 76 and moves to the inner side (X221) in the width direction W, the outer edge 622E of the folded portion 622 is formed on the inner surface of the wing 3. It hits and the movement inward of the width direction of the wing 3 can be controlled. FIG. 22 shows a state in which the outer edge 622E of the folded portion 622 is in contact with the inner surface of the wing 3. FIG. The outer edge 622E of the folded portion 622 is located on the outer side in the width direction of the absorbent core 31, and presses the wing 3 in the vicinity of the outer edge 31E of the absorbent core 31 toward the outer side in the width direction and toward the wearer ( X222). Therefore, it is possible to suppress the twisting of the wings 3 in the unfolding step 4, thereby suppressing problems such as sticking of the wing adhesive portions 72 to each other or sticking of the wing adhesive portions 72 to an unintended region.

The inner edge 63I of the first base point portion 63 may be arranged outside the absorbent core 31 in the width direction W in the central region S3. The first base point portion 63 serves as the standing fulcrum of the entire contracted portion 62 in the central region S3. Since the inner edge of the first base portion 63 is located outside the absorbent core 31 in the width direction W, when the wing 3 tries to move inward in the width direction, the inner surface of the wing 3 in the first folded state is The constricted portion 62 is easily abutted. Therefore, the flap portion can be pressed outward in the width direction, and twisting of the wing in the deployment step 4 can be suppressed.

Also, the inner edge 64I of the second base portion 64 may be arranged in a region overlapping the absorbent core 31 . The second base point portions 64 are provided as a pair spaced apart in the front-rear direction, and the region between the second base point portions 64 in the front-rear direction L rises with the second base point portions 64 as base points. Since the second base point portions 64 overlap the absorbent core 31 having relatively high rigidity, the standing fulcrum of the second base point portions 64 is stabilized, and the contraction portion 62 is contracted in the region between the second base point portions 64 in the front-rear direction L. becomes easier to stand up.

The flap fixing portion 92 overlaps an area between the pair of wing adhesive portions 72 in the thickness direction T, and may be separated from the wing adhesive portion 72 . In unfolding step 4, when the user pulls the packaging sheet 100, the flap release sheet 76 moves in the unfolding direction away from the wing adhesive portion 72 in the thickness direction T (X162 in FIG. 16, X17 in FIG. 17). At this time, since the wing adhesive portion 72 is separated from the flap fixing portion 92 in the width direction W, it is difficult to move in the unfolding direction together with the flap fixing portion 92, and it is easy to maintain the planar state. Therefore, in the unfolding step 4, the flap release sheet 76 can be easily peeled off from the wing adhesive portions 72, and problems such as the wing adhesive portions sticking to each other or the wing sticking portions 72 sticking to an unintended region can be suppressed.

The leak-proof unjoined portion 66 of the leak-proof gather 60 may reach the outer edge 622E of the folded portion 922 in the unfolded state. The outer edge of the folded portion 622 is not joined to the extension portion 621 and stands up against the extension portion 621 . The folded portions 622 are more likely to stand up on the outer side in the width direction W and on the wearer side, press the wings 3 outward in the width direction, and restrict the movement of the wings 3 inward in the width direction W.

The outer edge 65E of the leak-proof joint 65 may be arranged outside in the width direction W of the outer edge 31E of the absorbent core 31 . The upright fulcrum of the folded portion 622 in the region overlapping the second base point portion 64 is the outer edge 65E of the leak-proof joint portion 65 . Since the standing fulcrum of the folded portion 622 is located outside the absorbent core 31 in the width direction W, when the wing 3 in the folded state moves inward in the width direction W, the contracted portion 62 hits the inner surface of the wing. easy. By pressing the wings 3 outward in the width direction, movement of the wings 3 inward in the width direction can be restricted.

The leak-proof elastic member 61 may be arranged outside the flap release sheet 76 in the width direction W in the first folded state. A region outside the flap release sheet 76 in the first folded state in the width direction W is not covered with the flap release sheet 76, has low rigidity, and is easily deformed. By providing the leak-proof elastic member 61 of the folded portion 622 in the area, it is possible to suppress the inward movement of the wing 3 in the width direction in the area where the rigidity is relatively low.

A low basis weight portion 34 may be provided in the central region S3. Specifically, the central region S3 is provided with a first low basis weight portion 341 extending at least in the front-rear direction. The low basis weight portion 34 has a curved shape in which the center in the width direction protrudes forward and extends in the front-rear direction L. As shown in FIG. The absorbent core 31 in the central region S3 is easily bent with the first low basis weight portion 341 as a base point. More specifically, as shown in FIG. 22, when the wings 3 are pulled via the flap release sheet 76 and the wing adhesive portion 72, the center of the absorbent core 31 in the width direction W is separated from the flap release sheet 76. deforms into a curved shape. As a result, as shown in FIGS. 18 and 22 , the base of the wing 3 located in the area closer to the front edge than the second fold line FL2 moves inward in the width direction W. As shown in FIGS.

Therefore, in the unfolding step 4, the root of the wing 3 moves inward in the width direction W while the flap release sheet 76 moves in the unfolding direction (X162 in FIG. 16, X17 in FIG. 17). At this time, the contracted portion 62 presses the wings 3 outward in the width direction, and the wing adhesive portions 72 are easily maintained in a flat state. The occurrence of wrinkles or the like in the wing adhesive portion 72 can be suppressed.

The low basis weight portion 34 may overlap the region between the pair of wing adhesive portions 72 in the thickness direction T. As shown in FIG. The absorbent core 31 in the central region S3 is easily bent with the low basis weight portion 34 between the pair of wing adhesive portions 72 as a base point. Therefore, when the wing adhesive portion 72 is pulled through the flap release sheet 76, the wings 3 are more easily raised. At this time, the contracted portion 62 presses the wings 3 outward in the width direction W, and the wing adhesive portions 72 are easily maintained in a planar state. Therefore, it is possible to move the flap release sheet 76 in the unfolding direction and release the flap release sheet 76 from the wing adhesive part 72 while suppressing wrinkles or the like from occurring in the wing adhesive part 72 .

The low basis weight part 34 may be provided in a region that does not overlap the main body adhesive part 71 and the wing adhesive part 72 in the unfolded state of the package 110 . The area that does not overlap the body adhesive portion 71 and the wing adhesive portion 72 is an area that is not bonded to underwear or the like when worn and is easily deformed. By providing the low-basis weight portion 34 in this region, the absorbent core 31 can be easily deformed from the low-basis weight portion 34 as a base point, and the wings 3 can be more easily raised. The flap release sheet 76 and the wings 3 can be easily separated in the unfolding direction, and the flap release sheet 76 can be peeled off from the wing adhesive portion 72 while suppressing twisting of the wings 3 .

The package of the present embodiment is configured to absorb twisting of the absorbent article in the fourth unfolded state. Specifically, the second side low basis weight region R41 may extend in the width direction W in a region closer to the front edge than the flap fixing portion 92 in the unfolded state. Some users may find it difficult to pull the packaging sheet 100 substantially perpendicularly to the front edge 1F of the absorbent article 1 when unfolding it from the second fold line FL2. 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 to which force is applied via the packaging sheet 100 is pulled obliquely, and the flap fixing portion 92 and the front edge 1F of the absorbent article 1 is twisted. When the main body portion 2 in the region between the flap fixing portion 92 and the front edge 1F of the absorbent article 1 is twisted, it becomes difficult for the flap release sheet 76 and the wing adhesive portion 72 to move in the directions in which they separate from each other. Shearing stress is generated by the wing adhesive portion 72 , and the flap release sheet 76 may not be smoothly peeled off from the wing adhesive portion 72 .

Since the second side low basis weight area R41 extends in the width direction W in the area closer to the front edge 1F than the flap fixing portion 92, twisting of the main body portion 2 can be absorbed by the second side low basis weight area R41. Specifically, as shown in FIG. 23, the second side low-weight basis area R41 by the first low-weight basis area 341 is deformed, and the twist in the front-rear direction L and the width direction W can be absorbed. FIG. 23 is a diagram showing a deformed state of the absorbent core 31 in plan view of the absorbent article. FIG. 23(a) shows the state before deformation, and FIG. 23(b) shows the state after deformation. For example, when the wing 3 is pulled leftward and upward in FIG. Force is applied to the left and top. As shown in FIG. 23(b), when a leftward and upward force is applied to the body portion 2, the first low basis weight portion 341 is deformed. More specifically, the force X211 is applied to the left region of the main body 2, and the force X211 is applied to the right side of the main body. As a result, the first low basis weight portion 341 is deformed, the flap fixing portion 92 and the main body fixing portion 91 are tilted leftward and upward, and the twist between the flap fixing portion 92 and the wing adhesive portion 72 can be absorbed. FIG. 24 is a perspective view of the package 110 in the unfolding step 4, and schematically shows a state in which the twist of the area closer to the front edge than the flap fixing portion 92 is absorbed in the fourth unfolding step. Reference numeral 22WCL in FIG. 24 indicates the center of the main body 2 in the width direction W. As shown in FIG. Even if the packaging sheet cannot be pulled substantially perpendicularly to the front edge of the absorbent article, the second side low basis weight area R41 absorbs the twist and pulls the flap release sheet 76 against the wing adhesive portion 72. can be pulled almost vertically. Therefore, the flap peeling sheet 76 can be easily peeled off from the wing adhesive portion 72 .

The second side low basis weight area R41 may extend in the width direction W in the area between the flap fixing portion 92 and the first fold line FL1 in the unfolded state. In the fourth unfolding step, force in the unfolding direction is more likely to be applied to the region between the flap fixing portion 92 and the first fold line FL1. By providing the second side low basis weight region R41 in the region between the flap fixing portion and the first fold line FL1, the effect of absorbing the twist of the main body portion 2 can be more easily obtained.

The second side low basis weight area R41 may reach the outer edge of the absorbent core 31 . The region on the front edge 1F side of the absorbent article 1 and the region overlapping with the flap fixing portion 92 can be separated by the second side low basis weight region R41, and the effect of absorbing the twist of the main body portion 2 can be obtained more easily.

The body fixing portion 91 may have a first body fixing portion 911 . The first main body fixing portion 911 is provided in the first region R11 and is arranged closer to the first edge than the first fold 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 trailing edge side of the first fold line, the packaging sheet 100 is unfolded from the second fold line FL2 in unfolding step 4. When pulled, the absorbent article can be more easily spread out through the packaging sheet 100 and the body release sheet 75 . When the package 110 is moved in the rotation direction X14 in FIG. 14, the first main body fixing portion 911 is positioned outside the movement direction with respect to the area to be moved (the area on the rear side of the second fold line). . Therefore, it becomes easy to apply force to the entire area to be moved, and the package 110 can be moved more smoothly in the rotation direction X14, and the package 110 can be unfolded from the second fold line.

The main body fixing portion 91 may have a first main body fixing portion 911, and the low basis weight portion 34 may have an intermediate low basis weight region R44 located in the second region R12. The force applied to the packaging sheet 100 is transmitted to the body release sheet 75 via the body fixing portion 91 . The main body release sheet 75 is in contact with the main body adhesive part 71 and easily transmits force to the absorbent article 1 . Therefore, when the user applies force to the first fold line FL1 through the packaging sheet 100 in the third folded state, the force is transmitted to the main body release sheet 75 through the main body fixing portion 91, and the second fold line FL2. , the first fold side of the main body 2 is likely to move in the rotation directions X162 and X17 (FIGS. 16 and 17). When the first fold side of the main body portion 2 moves in the rotational direction around the second fold FL2 from the third folded state, the absorbent core 31 in the second region R12 deforms with the intermediate low mesh region R44 as a base point. As the absorbent core 31 in the second region R12 deforms, the flap release sheet 76 deforms following the absorbent core 31 in the second region R12, and the flap release sheet 76 deforms away from the wing adhesive portion 72. . Therefore, the flap peeling sheet 76 can be easily peeled off from the wing adhesive portion 72 . The intermediate low-basis area R44 may be configured such that the absorbent core 31 of the second area R12 is easily deformed, and may extend in the width direction or in the front-rear direction. More preferably, as in the present embodiment, the intermediate low-basis area R44 extends in the width direction and may also extend in the front-rear direction. That is, the middle low basis weight area R44 may be slanted with respect to the width direction and also be slanted with respect to the front-rear direction. With such a configuration, the absorbent core in the second region R12 can easily bend both in the front-rear direction and in the width direction, and the flap release sheet 76 can be more easily deformed so as to separate from the wing adhesive portion 72 .

The main body fixing portion 91 may have a first main body fixing portion 911 and a second main body fixing portion 912 . The second main body fixing portion 912 is arranged in the second region R12 between the first fold line FL1 and the second fold line FL2 in the unfolded state of the package. The packaging sheet 100 and the body release sheet 75 are joined by the body fixing portion 91 in both the first region R11 and the second region R12. When the packaging sheet 100 is pulled so as to unfold from the second fold line FL2, force can be applied to both sides of the first fold line FL1, and the absorbent article can be pulled through the packaging sheet 100 and the main body release sheet 75. is easier to deploy.

The first main body fixing portion 911 and the second main body fixing portion 912 may overlap in the thickness direction T in the third folded state. At least a portion of the first main body fixing portion 911 and at least a portion of the second main body fixing portion 912 may overlap. In the unfolding step 4, when force is applied to both sides of the first fold by the first main body fixing portion 911 and the second main body fixing portion 912, the force is easily transmitted through the packaging sheet and the main body release sheet. It becomes easier to deploy the absorbent article.

A boundary between the high mesh portion 33 and the medium mesh portion 35 may extend in the width direction W on the front edge 1F side of the absorbent article 1 relative to the third fold line FL3. The boundary between the high mesh portion 33 and the medium mesh portion 35 is provided at the outer edge of the high mesh portion 33 in the width direction and the end edge of the high mesh portion 33 in the front-rear direction L. Of these, the boundary between the high meshed portion 33 and the medium meshed portion 35 located on the front side may extend in the width direction W on the front side of the third fold line FL3. The boundary between the high basis weight portion 33 and the medium basis weight portion 35 is susceptible to deformation due to the difference in rigidity due to the difference in basis weight of the absorbent material. The boundary between the high mesh portion 33 and the medium mesh portion 35 can absorb twisting of the main body portion 2 in the expansion step 4 . The region on the front side of the third fold line FL3 is close to the part of the package such as the tag tape 102 where the package is gripped with one hand. Therefore, the torsion of the body portion 2 can be absorbed in the region near the portion where the package 110 is gripped. Even if the packaging sheet 100 cannot be pulled substantially perpendicularly to the front edge of the absorbent article, the boundary between the high basis weight portion 33 and the medium basis weight portion 35 absorbs the twist, and the flap release sheet 76 is winged. It can be pulled substantially perpendicularly to the adhesive portion 72 . Therefore, the flap peeling sheet 76 can be easily peeled off from the wing adhesive portion 72 .

In order to obtain the effect of absorbing the twist at the boundary between the high mesh portion 33 and the medium mesh portion 35, a low mesh portion 34 extending in the width direction W is provided in front of the boundary between the high mesh portion 33 and the medium mesh portion 35. may Twisting of the body portion 2 can be absorbed by the difference in rigidity due to the boundary between the high mesh portion 33 and the medium mesh portion 35 and the deformation of the low mesh portion.

In addition, in order to further obtain the effect of absorbing the twist at the boundary between the high basis weight portion 33 and the medium weight division portion 35, the adhesive portion 70 is not provided on the front side of the boundary between the high basis weight portion 33 and the medium weight division portion 35. The adhesive portion may be provided so as to extend in the width direction. The non-adhesive portion is a region that is not bonded to underwear or the like when worn and is easily deformed. By providing the non-adhesive portion extending in the width direction W, the region overlapping the non-adhesive portion of the body portion 2 is deformed, and twisting of the body portion 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 a 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 mesh portion 33 and the medium mesh portion 35, the low mesh portion 34 extending in the width direction, and the non-adhesive portion may be provided, or a combination of these may be provided. good. In addition, the boundary between the high basis weight portion 33 and the medium weight basis portion 35, the low weight basis portion 34 extending in the width direction, and the non-adhesive portion may reach the outer edge of the absorbent core 31, or may reach the outer edge of the absorbent core 31. does not have to reach

Also, the first compressed portion 81 overlaps the first low-weight basis portion 431 that constitutes the second side low-weight basis region R41. The first compressed portion 81 can suppress deformation of the first low basis weight portion 431 from being deformed, and the deformation of the absorbent core 31 can be maintained. In addition, the region where the second side low basis weight region R41 and the first pressing portion 81 overlap is more likely to have a difference in rigidity with respect to the surrounding absorbent core 31, and is more likely to be a deformation base point. Therefore, the absorbent core 31 can be deformed when the package is unfolded, and the flap peeling sheet 76 can be peeled off from the wing adhesive portion 72 more smoothly.

Similarly, the second compressed portion 82 overlaps the second low basis weight portion 432 that constitutes the second side low basis weight region R41 and the intermediate low basis weight region R44. The second compressed portion 82 can suppress the shape loss of the second low basis weight portion 432 due to deformation, and the deformation of the absorbent core 31 can be maintained. In addition, the region where the intermediate low basis weight region R44 and the second compressed portion 82 overlap is likely to have a difference in rigidity with respect to the surrounding absorbent core 31, and is more likely to become a deformation base point. Therefore, the absorbent core 31 can be deformed when the package is unfolded, and the flap peeling sheet 76 can be peeled off from the wing adhesive portion 72 more smoothly.

Similarly, the third compressed portion 83 overlaps with the third low basis weight portion 433 that constitutes the intermediate low basis weight region R44. The third compressed portion 83 can suppress the shape loss of the third low-basis portion 433 due to deformation, and the deformation of the absorbent core 31 can be maintained. In addition, the region where the intermediate low basis weight region R44 and the third compressed portion 83 overlap is likely to have a difference in rigidity with respect to the surrounding absorbent core 31, and is more likely to become a deformation base point. Therefore, the absorbent core 31 can be deformed when the package is unfolded, and the flap peeling sheet 76 can be peeled off from the wing adhesive portion 72 more smoothly.
