  The package of the absorbent article pulls the flap release sheet together with the packaging sheet while pulling the packaging sheet in the unfolding direction via the vicinity of the front end portion of the packaging body such as a tag tape. However, since the flap release sheet is in contact with the flap adhesive part, the flap part is easily deformed so as to follow the flap release sheet via the flap adhesive part. When the flap portion follows the flap release sheet, the tip of the flap portion rises with respect to the root of the flap portion. 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 portion, shear stress is generated by the flap adhesive portion. Therefore, it may be difficult to peel the flap release sheet from the flap adhesive part.

  Therefore, an absorbent article package in which the absorbent article is individually packaged by a packaging sheet, which can easily peel the flap release sheet from the flap adhesive portion, is desired.

(1) Outline of Embodiments At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
The package of the absorbent article which concerns on 1 aspect is a package of the absorbent article in which an absorbent article is individually wrapped with a packaging sheet. The absorbent article is disposed on a non-skin facing surface side of the main body part, a main body part having an absorbent core, a pair of flap parts extending to both outer sides in the width direction than the main body part, and the main body part A main body adhesive portion having an adhesive that stops the underwear, a pair of flap adhesive portions that are disposed on the non-skin facing surface side of each flap portion, and have an adhesive that stops the main body portion to the underwear, and the flap portion is A flap release sheet that covers the pair of flap adhesive portions in a state of being folded to the skin facing surface side of the main body portion. The packaging body is a first folded state in which the flap portion is folded to the skin facing surface side of the main body portion, and a first edge that is an outer edge in the front-rear direction of the packaging body extends in a width direction. Folded inside the package from the fold as a base point, and in the second folded state folded from the first fold as a base point, extends in the width direction and on the second edge side opposite to the first edge. The second fold is located at the base point and is folded inside the package. At least a part of the flap adhesive portion and the flap release sheet is disposed on the second edge side with respect to the second fold. In a third folded state in which the second fold is folded as a base point, a flap fixing portion that joins the packaging sheet and the flap peeling sheet in a region where the packaging sheet and the flap peeling sheet face each other is provided. The said absorption core has a low fabric weight part whose fabric weight of an absorption core is lower than the circumference | surroundings. The low weight portion has a second side low weight area that extends in the front-rear direction on the second edge side than the second fold line.

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

  According to a preferred aspect, the low weight portion has a front and rear low weight area parallel to the front and rear direction, and the front and rear low weight area is a region closer to the first edge than the first fold in the unfolded state. It does not have to be provided.

  According to this aspect, when the second fold is developed from the base point, the region on the first fold side with respect to the second fold is moved in the rotation direction with respect to the region on the second end edge side with respect to the second fold. At this time, the region between the first fold and the flap fixing portion is hardly deformed inward in the width direction, and the region on the second edge side relative to the second fold is relatively easily deformed inward in the width direction. Therefore, when the flap part is pulled through the flap release sheet and the flap adhesive part, the root part of the flap part moves inward in the width direction, and the rising angle of the flap part tends to increase.

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

  According to this aspect, when the second fold is developed from the base point, the region on the first edge side than the second fold is hardly deformed, and the region on the second edge side relative to the second fold is relatively wide. It becomes easy to deform inside. Therefore, when the flap part is pulled through the flap release sheet and the flap adhesive part, the root part of the flap part moves inward in the width direction, and the rising angle of the flap part tends to increase.

  According to a preferred aspect, the second low-weight area and the flap fixing portion are closer to the first fold side than the center in the front-rear direction of the second fold and the first fold in the third fold state. May be arranged.

  According to this aspect, since the flap fixing portion is separated from the second fold serving as the rotation axis when the second fold is expanded from the base point, the flap release sheet is pulled by pulling the packaging sheet during the expansion. It becomes easy to move in the deployment direction. At this time, since the deformation base point by the second side low weight area is provided on the first fold side, the rising angle of the flap portion can be further increased on the first fold side.

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

  According to this aspect, the deformation base point extending outward in the width direction toward the first fold side is formed in the region between the first fold line and the flap fixing portion. In the 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 by the deformation base point by the first side low weight area. A base point is formed. Therefore, when pulling the flap release sheet by the packaging sheet, the flap release sheet also has a deformation base point extending outward in the width direction from the flap fixing portion toward the first fold. The flap release sheet is deformed so as to be separated from the flap adhesive part, and the flap release sheet can be easily released from the flap adhesive part.

  According to a preferred aspect, the apparatus includes a main body release sheet that covers the main body adhesive portion and is joined to the packaging sheet via the main body fixing portion, and the main body fixing portion is more in the first fold than in the unfolded state. It is arrange | positioned at the area | region of 1 edge side, The said low fabric weight part may have an intermediate | middle low fabric weight area | region located in the area | region between the said 1st crease | fold and the said 2nd crease | fold in an unfolded state.

  According to this aspect, the force applied to the packaging sheet is transmitted to the main body peeling sheet via the main body fixing portion. The main body release sheet is in contact with the main body adhesive portion of the absorbent article and easily transmits force to the absorbent article. Therefore, in the third fold state, when the user applies a force to the first fold through the packaging sheet, the force is transmitted to the main body peeling sheet through the main body fixing portion, and the main body around the second fold. The first fold side of the part is easy to move in the rotation direction. When the first fold side of the main body moves from the third fold state in the rotational direction around the second fold, the absorption core in the region between the first fold and the second fold is deformed with the intermediate low weight area as a base point To do. When the absorption core in the region between the first fold and the second fold is deformed, the flap release sheet is deformed so as to be separated from the flap adhesive portion, and the flap release sheet can be easily peeled from the flap adhesive portion. it can.

  According to a preferred aspect, the second side low weight area may extend in the width direction in a region on the second end edge side with respect to the flap fixing portion in the unfolded state.

  According to this aspect, since the second side low weight area extends in the width direction in the second edge side area with respect to the flap fixing portion, the second side low weight area can absorb the twist. Even when the packaging sheet cannot be pulled substantially perpendicular to the second edge of the absorbent article, the second side low weight area absorbs the twist, and the flap release sheet is attached to the flap adhesive part. It can be pulled almost vertically. Therefore, a flap peeling sheet can be easily peeled from a flap adhesion part.

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

  According to this aspect, the force between the flap fixing portion and the first fold is more easily applied in the deployment direction in the fourth deployment step. By providing the second side low 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 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 with the flap fixing portion can be divided by the second side low-weighted region, and the effect of absorbing the twist of the main body can be obtained more easily. .

The flap release sheet 76 is joined to the outer surface 100B of the packaging sheet 100 via the flap fixing portion 92 in the third folded state. The flap fixing portion 92 is disposed on the front end edge 110F side of the package 110 with respect to the second fold FL2, and is disposed in a region where the packaging sheet 100 and the flap release sheet 76 face each other in the third folded state.

  As shown in FIG. 12, in the packaged state, the outer surface 100B of the packaging sheet 100 is joined to the flap release sheet 76 via the flap fixing portion 92, and the inner surface 100T of the packaging sheet 100 is connected to the main body via the main body fixing portion 91. Bonded to the release sheet 75. The main body fixing portion 91 and the flap fixing portion 92 overlap in the thickness direction T. It suffices that at least a part of the main body fixing part 91 and at least a part of the flap fixing part 92 overlap each other.

  In addition, although the flap peeling sheet 76 of this Embodiment is arrange | positioned ranging over a pair of wing adhesion part 72, in other forms, the flap peeling sheet 76 is isolate | separated to the width direction, and each wing adhesion It may be arranged so as to cover the portion 72. In the configuration in which the flap release sheet 76 covers each wing adhesive portion 72, the flap fixing portion 92 may be provided on each flap release sheet 76.

  The bonding strength between the packaging sheet 100 and the main body peeling sheet 75 by the main body fixing portion 91 is higher than the bonding strength between the main body peeling sheet 75 and the absorbent article by the main body adhesive portion 71. Therefore, at the time of use, when the main body release sheet 75 is pulled through the packaging sheet, the main body release sheet 75 is separated from the absorbent article 1 and the main body adhesive portion 71 without peeling off the packaging sheet 100 and the main body release sheet 75. To do.

  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 pulling the flap release sheet 76 through the packaging sheet at the time of use, the flap release sheet 76 is separated from the absorbent article and the main body adhesive portion 71 without peeling off the packaging sheet 100 and the flap release sheet 76. .

  Further, the bonding strength between the tag tape 102 and the packaging sheet 100 may be higher than the strength of the main body fixing portion 91 that joins the packaging sheet 100 and the main body peeling sheet 75. Therefore, the packaging body 110 can be developed while holding the tag tape 102 without damaging the main body fixing portion 91 that joins the packaging sheet 100 and the main body peeling sheet 75.

  The bonding strength between the tag tape 102 and the packaging sheet 100 may be higher than the bonding strength between the main body peeling sheet 75 and the main body adhesive portion 71. Further, 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 the present embodiment, the user begins to unfold with the package 110 near the tag tape 102 and the vicinity of the front edge of the absorbent article 1 until the deployment is completed. The packaging sheet 100 and the absorbent article can be separated without re-holding. 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 peeling sheet 75 and the main body adhesive portion 71, the packaging sheet 100 is maintained while maintaining the bonding between the tag tape 102 and the packaging sheet 100. The main body adhesive portion 71 and the main body peeling sheet 75 can be peeled off. 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 packaging sheet 100 is maintained while maintaining the bonding between the tag tape 102 and the packaging sheet 100. The wing adhesive part 72 and the flap peeling sheet 76 can be peeled through.

  Next, with reference to FIG. 11 to FIG. FIG. 11 is a perspective view of a packaging state in which the absorbent article 1 is individually packaged by the packaging sheet 100. 12 is a cross-sectional view taken along line 11A-11A shown in FIG. 13 to 17 are diagrams for explaining a developing process in a cross section based on the line 11A-11A shown in FIG. FIG. 13 shows the package 110 in the unfolding steps 2 and 3. FIG. 14 shows the package 110 in the unfolding step 4. FIG. 15 shows the package 110 in the unfolding step 5. FIG. 16 shows the package 110 in the unfolding steps 6 and 7. FIG. 17 shows the package 110 in the unfolding step 7. FIG. 18 is a view showing the package 110 in the unfolding step 4. 19 is a cross-sectional view taken along line 13A-13A in FIG. 20 to 22 are views showing the package in the unfolding step 4 in a cross section with reference to the line 13A-13A shown in FIG. For convenience of explanation, the leak-proof gathers are omitted in FIGS. 19 and 20, and the leak-proof gathers 60 are shown in FIGS. In addition, the expansion | deployment aspect shown below is an example and may be expand | deployed in the aspect which changes with users.

  First, the user grasps the tag tape 102 and develops the absorbent article 1 and the packaging sheet 100 based on the third fold FL3 in order to deploy the package 110 from the packaging state shown in FIGS. 11 and 12. (Development process 1). FIG. 13 shows the package 110 in a third folded state that is folded from the first fold line FL1 and the second fold line FL2 and not folded by the third fold line FL3.

  Next, the user peels off the packaging sheet 100 from the main body adhesive portion 71 (deployment 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, and the packaging sheet 100 is moved away from the main body adhesive portion 71. At this time, since the main body peeling sheet 75 is joined to the packaging sheet 100 by the main body fixing portion 91, the main body peeling sheet 75 moves together with the packaging sheet 100. In FIG. 13, the packaging sheet 100 and the main body peeling sheet 75 in the expansion | deployment process 2 are shown with a dashed-dotted line.

  After the user peels the packaging sheet 100 from the main body 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 body adhesive portion 71. To move away from (development step 3). In FIG. 13, the packaging sheet 100 and the main body peeling sheet 75 in the expansion | deployment process 3 are shown with a continuous line.

  As shown in FIG. 14, the user then deploys the packaging sheet 100 and the absorbent article 1 with the second fold FL2 as a base point (deployment step 4). In the unfolding step 4, the package 110 is unfolded from the third folded state to the second folded state. In the third folded state in which the second fold line FL2 is folded as a base point, the packaging sheet 100 and the flap release sheet 76 are joined via the flap fixing portion 92. Therefore, when the package 110 is expanded from the third folded state to the second folded state, the flap release sheet 76 is pulled in a direction 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 FL2. Thereby, as shown in FIG. 14, the packaging sheet 100, the main body 2, and the flap release sheet 76 move in the rotation direction X <b> 14, and the flap release sheet 76 moves away from the wing adhesive portion 72. FIG. 14 shows a state where the flap release sheet moves in the rotation 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 not folded with the second fold FL2 as the base point but are unfolded (deployment step 5). In the state shown in FIG. 15, only the flap release sheet 76 is folded at the second fold FL2, and the other members are in the first folded state that is not folded at the second fold 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 the position corresponding to the hip flap adhesive portion 73 is virtually shown.

  Next, as shown in FIG. 16, the user moves the packaging sheet 100 in the rotation direction X161 from the first fold FL1 as a base point (deployment step 6). At this time, the main body release sheet 75 and the flap release sheet 76 arranged with the packaging sheet 100 interposed therebetween move in the rotation direction X161 with the first fold FL1 as a base point. In the first region R <b> 11, the main body peeling sheet 75 peels from the main body adhesive portion 71. At this time, the flap release sheet 76 located on the rear edge side of the second fold 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 FL1 as a base point (deployment step 7). FIG. 17 shows a state in which the region on the rear edge side of the packaging sheet 100 and the absorbent article 1 relative to the first fold FL1 is moved in the rotation direction X17 with the first fold FL1 as a base point. The user can peel off the main body release sheet 75 and the flap release sheet 76 together with the packaging sheet 100 to expose the main body adhesive part 71, the wing adhesive part 72, and the hip flap adhesive part 73. According to such an unfolding method, the user starts unfolding with the package 110 near the tag tape 102 and the vicinity of the front end edge of the absorbent article 1, and does not hold the hand until the unpacking 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 FL1, and the packaging body in the vicinity of the first fold FL1 is moved in the rotation direction from the second fold FL2. can do. When deployed in this manner, the force for deploying 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 end edge 100F side of the packaging sheet 100 is grasped and the packaging sheet 100 is pulled and deployed as in the development step 4 described above, following the previous development step 3. Specifically, for example, the front end edge 1F of the absorbent article 1 is held with one hand, the front end edge 100F of the packaging sheet 100 is held with the other hand, and the first fold FL1 and the front end of the absorbent article 1 are held. In the region between the edges 1F, the packaging sheet 100 is peeled off from the main body adhesive portion 71 (deployment step 3), and the packaging sheet 100 and the absorbent article 1 are gripped as they are and the first fold FL1 is interposed via the packaging sheet 100. Then, the package 110 is developed (development process 4). As described above, the package 110 of the absorbent article according to the present embodiment grips the packaging sheet 100 in the unfolding step 4 and unfolds the main body release sheet 75 from the main body adhesive portion 71 when the packaging body 110 is unfolded. The flap release sheet 76 can be easily peeled off from the wing adhesive portion 72 while being easily peeled off.

  As described above, when a force is applied to the first fold FL1 via the packaging sheet 100 in the unfolding step 4, the packaging body 110 rotates in the first fold FL1 side about the second fold FL2. Then, the flap release sheet 76 moves in the rotational direction X14 together with the packaging sheet 100, and the flap release sheet 76 moves away from the wing adhesive portion 72 in the third region R13.

  When the first fold FL1 side is moved in the rotation direction X14 around 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 when 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, and the flap release sheet 76 is provided via the flap fixing portion 92. 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, and the flap release sheet 76 may be difficult to be separated from the wing adhesive portion 72 in the third region R13.

  In the package 110 according to the present embodiment, the force applied to the packaging sheet 100 is transmitted to the main body peeling sheet 75 via 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 easily transmits force to the absorbent article 1. When the user applies a force with the first fold FL1 side in the rotational direction X14 via the packaging sheet 100, the force is transmitted to the main body peeling sheet 75 via the main body fixing portion 91, and the first absorbent article 1 is The fold FL1 side is easy to move in the rotational direction X14.

  The main body fixing portion 91 overlaps the flap fixing portion 92 in the thickness direction T. Therefore, while transmitting force to the main body peeling sheet 75 and the absorbent article 1 from the packaging sheet 100 via the main body fixing | fixed part 91, when the packaging sheet 100 and the main body peeling sheet 75 move to the rotation direction X14, flap release sheet 76 is provided. Can easily move 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 off from the main 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 of the second fold line FL2 and the first fold line FL1 in the third folded state in which the package 110 is folded based on the first fold line FL1 and the second fold line FL2. You may arrange | position on the 1st fold FL1 side rather than the center. The center in the front-rear direction L of the second fold line FL2 and the first fold line FL1 is the center in the front-rear direction of the third region R13. Since the main body fixing portion 91 and the flap fixing portion 92 are separated from the second fold FL2, which is the rotation axis in the unfolding step 4, in the unfolding step 4, the first fold FL1 side is centered on the second fold FL2 in the rotation direction. It becomes easy to move. It should be noted that at least a part of the main body fixing part 91 and at least a part of the flap fixing part 92 may be arranged closer to the first fold FL1 side than the centers in the front-rear direction L of the second fold FL2 and the first fold FL1. . More preferably, the main body fixing portion 91 and the flap fixing portion 92 are preferably biased toward the first fold FL1 side from the center in the front-rear direction L of the second fold FL2 and the first fold 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 package 110 is folded based on the first fold line FL1 and the second fold line FL2. Good. When the flap release sheet 76 moves away from the wing adhesive portion 72 in the unfolding step 4, the area in contact with the flap fixing portion 92 in the flap release sheet 76 moves first, and the wing adhesive portion 72 in the flap release sheet 76 moves to the wing adhesive portion 72. The contact area moves following. This is because the wing adhesive portion 72 and the flap fixing portion 92 do not overlap. As shown in FIG.18 and FIG.20, the front-end | tip of each wing 3 moves to the rotation direction X18 from the root of each wing, and stands up from the skin opposing surface side T1 of the absorbent article 1. As shown in FIG. The pair of wings 3 and the main body 2 are disposed so as to surround a substantially triangular space.

  In the state where the wing 3 and the main body 2 are arranged to form a triangle, the center in the width direction W of the flap release sheet 76 (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 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 moves in a state where the tip of the wing 3 is deformed so as to rise from the root of the wing, so that the outer edge of the wing adhesive portion 72 in the first folded state becomes the flap release sheet 76. Begin to peel off. The flap release sheet 76 is gradually separated from the wing adhesive portion 72, and the flap release sheet 76 can be easily released 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 so as to rise with respect to the root of the wing 3 in the unfolding step 4, the tip of each wing is pulled toward the center side in the width direction W of the main body 2 to increase the rising angle of the wing 3. can do. Therefore, the flap release sheet 76 can be more easily peeled from the wing adhesive portion 72.

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

  The flap fixing portion 92 may be disposed separately 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 rise with respect to the root of the wing 3 in the unfolding step 4, the rising angle of the wing 3 can be further increased. Therefore, the flap release sheet 76 can be more easily peeled from the wing adhesive portion 72.

  The front end edge of the first wing adhesive portion 721 may be disposed behind the front end 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 on the side away from the second fold line FL <b> 2 that is the development base point in the development process 4. The second wing adhesive portion 722 located on the base side of the wing 3 extends to the side farther from the second fold FL2 than the first wing adhesive portion 721 located on the tip side of the wing 3. The length in the front-rear direction of the wing adhesive portion located on the inner side in the width direction in the first folded state in which the wing 3 is folded to the skin facing surface side of the main body portion 2 is short. Therefore, when the tip of each wing 3 is deformed so as to rise with respect to the root of each wing 3, the tip side of the wing 3 is likely to rise earlier than the root side of the wing 3. The rising angle of the wing 3 is increased, the outer edge of the wing adhesive portion 72 and the flap release sheet 76 are gradually released, and the flap release sheet 76 can be more easily released from the wing adhesive portion 72.

  Further, the second side low weight area R41 of the low weight portion 34 may extend in the front-rear direction L on the front end edge side with respect to the second fold line FL2. The absorption core 31 in the region on the front end edge side of the second fold line FL2 is formed with a deformation base point extending in the front-rear direction L by the second side low weight region R41, and is easily bent in the width direction W. Therefore, when the wing 3 is pulled through the flap release sheet 76 and the wing adhesive portion 72 in the unfolding step 4, the center in the width direction W of the region on the front edge side of the second fold FL2 is away from the flap release sheet 76. Transforms away. The absorbent core 31 in the region on the front end edge side of the second fold FL2 is deformed into a curved shape. Accordingly, as shown in FIG. 18, the root of the wing 3 located in the region on the front end edge side of the second fold line FL2 moves inward in the width direction W, and the rising angle of the wing 3 increases. Therefore, the tip of each wing rises with the base of each wing as a base point, and is disposed so as to surround a substantially triangular space by the pair of wings 3 and the main body 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 released from the wing adhesive portion 72.

  Further, the front and rear low weight area R42 of the low weight portion 34 does not have to be provided in the first area R11 on the rear edge side of the first fold FL1 in the unfolded state. In the unfolding step 4, when unfolding with the second fold FL2 as the base point, the region on the first fold FL1 side relative to the second fold FL2 is moved in the rotational direction with respect to the region on the front edge side of the second fold FL2. . At this time, since the region between the first fold FL1 and the flap fixing portion 92 is difficult to be deformed inward in the width direction, the region on the front edge side relative to the second fold FL2 is relatively easily deformed 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 root of the wing moves inward in the width direction W, and the rising angle of the wing 3 tends to increase. Therefore, the flap peeling sheet 76 can be easily peeled from the wing adhesive portion 72.

  In another embodiment, the front and rear low weight area R42 may not be provided in the second area R12. Since both the first region R11 and the second region R12 are not provided with the front and back low-weight area R42, in the unfolding step 4, the region on the first edge side becomes more difficult to deform than the second fold FL2, and the relative Therefore, the region on the front edge side of the second fold line FL2 is easily deformed inward in the width direction W. Therefore, the rising angle of the wing 3 becomes larger, and the flap release sheet 76 can be easily peeled from the wing adhesive portion 72.

  The second side low weight area R41 and the flap fixing portion 92 are arranged before and after the second fold FL2 and the first fold FL1 in the third folded state in which the package 110 is folded based on the first fold FL1 and the second fold FL2. It may be arranged on the first fold FL1 side with respect to the center in the direction L. The flap fixing sheet 92 is separated from the second fold line FL2, which serves as a rotation axis when the second fold line FL2 is deployed as a base point, and the flap release sheet 76 is deployed by pulling the packaging sheet 100 during the deployment. It becomes easy to move in the direction. At this time, since the deformation base point by the second side low weight area R41 is provided on the first fold FL1 side, the rising angle of the wing 3 can be further increased on the first fold FL1 side.

  The first side low weight region R43 of the low weight portion 34 may extend outward in the width direction W toward the first fold FL1 side in the region between the first fold FL1 and the flap fixing portion 92 in the deployed 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 the sectional view in the thickness direction, the absorbent core 31 closer to the flap release sheet than the flap fixing portion 92 is in the width direction from the flap fixing portion 92 toward the first fold FL1 by the deformation base point by the first side low weight area R43. A deformation base point extending outside W is formed. Therefore, when the flap release sheet 76 is pulled through the packaging sheet 100 in the unfolding 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 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 released from the wing adhesive portion 72.

  The packaging body of this Embodiment is comprised so that the malfunction which the wing adhesion part 72 as a flap adhesion part adhere | attaches unintentionally can be suppressed in a 4th expansion | deployment state. Specifically, the outer edge 622E of the folded portion 622 may be disposed on the outer side in the width direction with respect to the absorbent core 31. The folded-back portion 622 of the contraction portion 62 has a leak-proof elastic member 61, and stands on the outer side in the width direction and on the wearer side with the inner edge of the extension portion 621 as a base point in the central region S3.

  As shown in FIG. 21, in a state where the wing 3 is folded back with the flap fold FL5 as a base point, a leak-proof gather 60 is disposed between the wing 3 and the main body portion 2 with the flap fold FL5 interposed therebetween. Yes. Therefore, the inner surface (the skin facing surface side in the unfolded state) of the wing 3 in the folded state is disposed to face the outer edge 622E of the folded portion 622. As shown in FIG. 22, when the wing 3 is pulled together with the flap release sheet 76 and moved inward in the width direction W (X221) in the unfolding step 4, the outer edge 622E of the folded portion 622 is formed on the inner surface of the wing 3. It is possible to restrict the movement of the wing 3 inward in the width direction. FIG. 22 shows a state in which the outer edge 622E of the folded portion 622 hits the inner surface of the wing 3. The outer edge 622E of the folded portion 622 is positioned outside the absorbent core 31 in the width direction, and presses the wing 3 toward the outer side in the width direction and toward the wearer in the vicinity of the outer edge 31E of the absorbent core 31 ( X222). Therefore, the wing 3 can be prevented from swaying in the unfolding step 4, and problems such as the wing adhesive portions 72 sticking to each other or the wing adhesive portion 72 sticking to an unintended region can be suppressed.

  The inner edge 63I of the first base portion 63 may be disposed outside the absorbent core 31 in the width direction W in the central region S3. The standing fulcrum of the entire contraction part 62 in the central area S3 is the first base point part 63. Since the inner edge of the first base point 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 edge of the wing 3 in the first folded state The contraction part 62 is easy to hit. Therefore, a flap part can be pressed toward the outer side of the width direction, and the swing of the wing in the expansion | deployment process 4 can be suppressed.

  Further, the inner edge 64 </ b> I of the second base point portion 64 may be disposed in a region overlapping the absorbent core 31. A pair of second base points 64 are provided with a space in the front-rear direction, and an area between the second base points 64 in the front-rear direction L stands with the second base point 64 as a base point. Since the second base point portion 64 overlaps the absorption core 31 having relatively high rigidity, the standing fulcrum by the second base point portion 64 is stabilized, and the contraction portion 62 is formed 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 the region between the pair of wing adhesive portions 72 in the thickness direction T, and may be separated from the wing adhesive portion 72. In the 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 and 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 deployment direction together with the flap fixing portion 92 and it is easy to maintain a flat state. Therefore, in the expansion | deployment process 4, the flap peeling sheet 76 is easy to peel from the wing adhesive part 72, and the malfunction that the wing adhesive parts stick together or the wing adhesive part 72 sticks to the area | region which is not intended can be suppressed.

  The leak-proof non-joining portion 66 of the leak-proof gather 60 may reach the outer edge 622E of the folded portion 922 in the deployed state. The outer edge of the folded portion 622 stands up with respect to the extended portion 621 without being joined to the extended portion 621. The folding | returning part 622 becomes easy to stand by the wearer side and the outer side of the width direction W, presses the wing 3 toward the outer side of the width direction, and can control the movement to the inner side of the width direction W of the wing 3.

  The outer edge 65E of the leak-proof joint portion 65 may be disposed outside the outer edge 31E of the absorbent core 31 in the width direction W. The rising fulcrum of the folded-back portion 622 in the region overlapping with 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 folded wing 3 tries to move inward in the width direction W, the contracted portion 62 hits the inner surface of the wing. easy. The wing 3 can be pressed toward the outside in the width direction to restrict the movement of the wing 3 in the width direction.

  The leak-proof elastic member 61 may be disposed outside the flap release sheet 76 in the width direction W in the first folded state. The region outside in the width direction W with respect to the flap release sheet 76 in the first folded state 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 region, it is possible to suppress movement of the wing 3 in the width direction in the region having relatively low rigidity.

  The low weight part 34 may be provided in the central region S3. Specifically, a first low weight portion 341 that extends at least in the front-rear direction is provided in the central area S3. The low basis weight 34 has a curved shape with the center in the width direction protruding toward the front side, and extends in the front-rear direction L. The absorption core 31 in the central region S3 is easily bent with the first low weight portion 341 as a base 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 absorbent core 31 in the width direction W is separated from the flap release sheet 76. It deforms into a curved shape. 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 fold line FL <b> 2 moves inward in the width direction W.

  Therefore, in the unfolding step 4, the flap release sheet 76 moves in the unfolding direction while the base of the wing 3 moves inward in the width direction W (X162 in FIG. 16 and X17 in FIG. 17). At this time, the wing 3 is pressed outward in the width direction by the contraction portion 62, and the wing adhesive portion 72 is easily maintained in a planar state. Generation of wrinkles or the like in the wing adhesive portion 72 can be suppressed.

  In the thickness direction T, the low basis weight portion 34 may overlap an area between the pair of wing adhesive portions 72. The absorbent core 31 in the central area S3 is easily bent between the pair of wing adhesive portions 72 with the low basis weight 34 as a base point. Therefore, when the wing adhesive portion 72 is pulled through the flap release sheet 76, the wing 3 is more likely to rise. At this time, the wing 3 is pressed to the outside in the width direction W by the contraction portion 62, and the wing adhesive portion 72 is easily maintained in a planar state. Therefore, it is possible to move the flap release sheet 76 from the wing adhesive portion 72 by moving the flap release sheet 76 in the developing direction while suppressing wrinkles and the like from being generated in the wing adhesive portion 72.

  The low basis weight portion 34 may be provided in a region that does not overlap the main body adhesive portion 71 and the wing adhesive portion 72 in the expanded state of the package 110. The region that does not overlap with the main body adhesive portion 71 and the wing adhesive portion 72 is an area that is not joined to the undergarment or the like at the time of wearing and is easily deformed. By providing the low weight portion 34 in the region, the absorbent core 31 is likely to be deformed from the low weight portion 34 with the base point, and the wing 3 is more likely to rise. The flap release sheet 76 and the wing 3 can be easily separated in the developing direction, and the flap release sheet 76 can be released from the wing adhesive portion 72 while suppressing the wing 3 from being twisted.

  The package of the present embodiment is configured to absorb the twist of the absorbent article in the fourth expanded state. Specifically, the second side low weight area R41 may extend in the width direction W in the area on the front edge side of the flap fixing portion 92 in the unfolded state. When developing with the second fold FL2 as a base point, it may be difficult for some users to pull the packaging sheet 100 substantially perpendicular to the front edge 1F of the absorbent article 1. When the front end 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 is pulled. And the main body 2 in the region between the front end edge 1F of the absorbent article 1 is twisted. When the main body 2 in the region between the flap fixing portion 92 and the front end edge 1F of the absorbent article 1 is twisted, the flap peeling sheet 76 and the wing adhesive portion 72 are difficult to move in the direction of peeling from each other. There is a possibility that shear stress is generated by the wing adhesive portion 72, and the flap release sheet 76 cannot be smoothly released from the wing adhesive portion 72.

  The second side low weight area R41 extends in the width direction W in the area closer to the front end edge 1F than the flap fixing portion 92, so that the twist of the main body 2 can be absorbed by the second side low weight area R41. Specifically, as shown in FIG. 23, the second low-weight area R41 by the first low-weight portion 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 illustrating a deformed state of the absorbent core 31 in a plan view of the absorbent article. FIG. 23A shows a state before deformation, and FIG. 23B shows a state after deformation. For example, when the wing 3 is pulled to the left side and the upper side in FIG. 21 with respect to the front edge 1F of the absorbent article via the flap fixing portion 92 and the packaging sheet 100, the main body portion 2 sandwiched by the wing 3 Force is applied to the left side and the upper side. As shown in FIG. 23B, the first low weight portion 341 is deformed when a force is applied to the main body 2 toward the left side and the upper side. More specifically, a force X211 is applied to the left region of the main body 2, and a force X211 is applied to the right side of the main body. Thereby, the 1st low weight part 341 deform | transforms, the flap fixing | fixed part 92 and the main body fixing | fixed part 91 incline toward the left side and the upper side, and can absorb the twist by the flap fixing | fixed part 92 and the wing adhesion part 72. FIG. 24 is a perspective view of the package 110 in the unfolding step 4, and schematically shows a state in which the twist in the region on the front edge side of the flap fixing portion 92 is absorbed in the fourth unfolding step. 24 indicates the center in the width direction W of the main body 2. Even when the packaging sheet cannot be pulled substantially perpendicular to the front edge of the absorbent article, the second side low weight area R41 absorbs the twist, and the flap release sheet 76 is attached to the wing adhesive portion 72. Can be pulled almost vertically. Therefore, the flap peeling sheet 76 can be easily peeled from the wing adhesive portion 72.

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

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

  The main body fixing portion 91 may include a first main body fixing portion 911. The first main body fixing portion 911 is provided in the first region R11, and is disposed closer to the first end edge than the first fold FL1. Since the packaging sheet 100 and the main body peeling sheet 75 are joined at the first main body fixing portion 911 on the rear edge side of the first fold line, the packaging sheet 100 is developed so as to be developed based on the second fold line FL2 in the unfolding step 4. When pulled, the absorbent article can be more easily developed through the packaging sheet 100 and the main body peeling sheet 75. The first main body fixing portion 911 is located outside the moving direction with respect to the area to be moved (area behind the second fold) when the package 110 is moved in the rotation direction X14 of FIG. . Therefore, it becomes easy to apply force to the whole area to be moved, and the package 110 can be moved more smoothly in the rotation direction X14, and the package 110 can be developed based on the second fold.

  The main body fixing portion 91 may include a first main body fixing portion 911, and the low weight per unit area 34 may include a middle low per unit area R44 located in the second region R12. The force applied to the packaging sheet 100 is transmitted to the main body peeling sheet 75 via the main body fixing portion 91. The main body peeling sheet 75 is in contact with the main body adhesive portion 71 and easily transmits force to the absorbent article 1. Therefore, when the user applies a force to the first fold FL1 via the packaging sheet 100 in the third folded state, the force is transmitted to the main body peeling sheet 75 via the main body fixing portion 91, and the second fold FL2 The first fold side of the main body 2 is easily moved in the rotational 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 of the second region R12 is deformed with the intermediate low weighted region R44 as a base point. When the absorbent core 31 in the second region R12 is deformed, the flap release sheet 76 is deformed following the absorbent core 31 in the second region R12, and the flap release sheet 76 is deformed so as to be separated from the wing adhesive portion 72. . Therefore, the flap peeling sheet 76 can be easily peeled from the wing adhesive portion 72. The intermediate low weight area R44 only needs to be configured so that the absorbent core 31 of the second area R12 can be 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 weight area R44 may extend in the width direction and may also extend in the front-rear direction. That is, the intermediate low weight area R44 may be inclined with respect to the width direction and also with respect to the front-rear direction. According to such a configuration, the absorbent core in 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 separated from the wing adhesive portion 72.

  The main body fixing portion 91 may include a first main body fixing portion 911 and a second main body fixing portion 912. The second main body fixing portion 912 is disposed in the second region R12 between the first fold line FL1 and the second fold 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 main body peeling sheet 75 are joined by the main body fixing portion 91. When the packaging sheet 100 is pulled so as to develop from the second fold FL2 as a base point, a force can be applied to both sides of the first fold FL1, and the absorbent article is interposed via the packaging sheet 100 and the main body release sheet 75. It becomes 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. It suffices that at least a part of the first main body fixing part 911 and at least a part of the second main body fixing part 912 overlap each other. In the unfolding step 4, when a force is applied to both sides sandwiching the first fold by the first main body fixing portion 911 and the second main body fixing portion 912, the force is easily transmitted, and the force is transmitted via the packaging sheet and the main body release sheet. It becomes easier to deploy the absorbent article.

  The boundary between the high weighted portion 33 and the middle weighted portion 35 may extend in the width direction W closer to the front end edge 1F of the absorbent article 1 than the third fold FL3. The boundary between the high weighted portion 33 and the middle weighted portion 35 is provided at the outer edge in the width direction of the high weighted portion 33 and the end edge in the front-rear direction L of the high weighted portion 33. Among these, the boundary between the high weighted portion 33 and the middle weighted portion 35 positioned on the front side may extend in the width direction W on the front side of the third fold FL3. The boundary between the high weight portion 33 and the middle weight portion 35 is easily deformed due to a difference in rigidity due to a difference in weight of the absorbent material. The torsion of the main body 2 in the unfolding step 4 can be absorbed by the boundary between the high weight portion 33 and the medium weight portion 35. The region on the front side of the third fold FL3 is close to the portion of the package that holds the package with one hand, such as the tag tape 102. Therefore, the twist 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 perpendicular to the front edge of the absorbent article, the boundary between the high weight portion 33 and the middle weight portion 35 absorbs the twist, and the flap release sheet 76 is winged. It can be pulled substantially perpendicular to the adhesive portion 72. Therefore, the flap peeling sheet 76 can be easily peeled from the wing adhesive portion 72.

  In order to obtain the effect of absorbing the twist caused by the boundary between the high weight portion 33 and the middle weight portion 35, a low weight portion 34 extending in the width direction W is provided on the front side of the boundary between the high weight portion 33 and the middle weight portion 35. May be. The torsion of the main body 2 can be absorbed by the rigidity difference due to the boundary between the high weight portion 33 and the middle weight portion 35 and the deformation of the low weight portion.

  Moreover, in order to obtain the effect which absorbs the twist by the boundary of the high fabric weight part 33 and the middle fabric weight part 35, the adhesion part 70 is not provided in the front side rather than the boundary of the high fabric weight part 33 and the middle fabric weight part 35. You may provide an adhesion part so that it may extend in the width direction. The non-adhesive part is an area that is not joined to the underwear or the like at the time of wearing and is easily deformed. By providing the non-adhesive part extending in the width direction W, the region overlapping the non-adhesive part of the main body part 2 is deformed, and the twist of the main body part 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 when 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 weight portion 33 and the middle weight portion 35, the low weight portion 34 extending in the width direction, and the non-adhesive portion may be provided, or a combination thereof may be provided. Good. Further, the boundary between the high weighted portion 33 and the middle weighted portion 35, the low weighted portion 34 extending in the width direction, and the non-adhesive portion may reach the outer edge of the absorbent core 31, or the outer edge of the absorbent core 31. It is not necessary to have reached.

  Moreover, the 1st pressing part 81 has overlapped with the 1st low weight part 431 which comprises 2nd side low weight area | region R41. By the 1st pressing part 81, the shape loss of the 1st low weight part 431 by a deformation | transformation can be suppressed, and the deformation | transformation of the absorption core 31 can be continued. In addition, the region where the second side low weight area R41 and the first compressed portion 81 overlap is more likely to cause a difference in rigidity with respect to the surrounding absorbent core 31, and more likely to be a deformation base point. Therefore, the absorbent core 31 can be deformed when the package is unfolded, and the flap release sheet 76 can be more smoothly released from the wing adhesive portion 72.

  Similarly, the 2nd pressing part 82 has overlapped with the 2nd low weight part 432 which comprises 2nd side low weight area | region R41 and intermediate | middle low weight area R44. By the 2nd pressing part 82, the deformation | transformation of the 2nd low weight part 432 by a deformation | transformation can be suppressed, and the deformation | transformation of the absorption core 31 can be continued. Further, the region where the intermediate low weight area R44 and the second compressed portion 82 overlap is likely to cause 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 release sheet 76 can be more smoothly released from the wing adhesive portion 72.

  Similarly, the 3rd pressing part 83 has overlapped with the 3rd low weight part 433 which comprises middle low weight area | region R44. By the 3rd pressing part 83, the shape loss of the 3rd low weight part 433 by a deformation | transformation can be suppressed, and the deformation | transformation of the absorption core 31 can be continued. Further, the region where the intermediate low weight area R44 and the third pressing portion 83 overlap with each other tends to cause a difference in rigidity with respect to the surrounding absorbent core 31, and more easily becomes a deformation base point. Therefore, the absorbent core 31 can be deformed when the package is unfolded, and the flap release sheet 76 can be more smoothly released from the wing adhesive portion 72.
