(1) Overview of Embodiments At least the following matters will become clear from the description of this specification and the accompanying drawings.
An absorbent article package according to one aspect includes an absorbent article having a body adhesive portion for attaching at least a region overlapping an absorbent core to a worn article, and an absorbent article disposed on the non-skin side of the absorbent article. and a packaging material. The absorbent article packaging body is in a packaging state in which the absorbent article and the packaging material are individually wrapped in the packaging material by folding the absorbent article and the packaging material from the unfolded state with a plurality of width creases along the width direction as base points. becomes. The outer edge in the front-rear direction of the packaging material has a packaging outer edge arranged on the outer surface of the packaging body in the packaging state and a packaging inner edge positioned inside the packaging body in the packaging state. The packaging body has side joints for joining the outer sides of the packaging material in the width direction. The width crease has a first crease and a second crease adjacent to the first crease and positioned closer to the outer edge of the package than the first crease in the unfolded state. The side joints include a first side joint that joins the packaging materials together in a first folded state folded along the first crease, and a first side joint that joins the packaging materials together in a second folded state folded along the second creases. and a second side joint that joins the The packaging material forms a pocket sandwiched between the pair of first side joints in the first folded state. The peel strength of the first side joint portion is higher than the peel strength of the second side joint portion when unfolding from the second folded state to the first folded state. According to this aspect, when the user performs an operation to peel off the first side joint portion to unfold the first side joint portion, the peel strength of the first side joint portion is equal to the peel strength of the second side joint portion. Therefore, even if an attempt is made to unfold the first folded state with the same force as when unfolding from the second folded state to the first folded state, the first side joint portion is not peeled off, and the first side joint portion is not separated. The bonded state can be maintained. By taking out the absorbent article from the packaging material side while maintaining the joined state of the first side joint portion, the absorbent article can be taken out while maintaining the shape of the pocket. Therefore, the absorbent article can be hygienically disposed of using the pocket.

An absorbent article package according to another aspect includes an absorbent article having a body adhesive portion for fastening at least a region overlapping an absorbent core to a worn article, and an absorbent article arranged on the non-skin side of the absorbent article, It has a main body release sheet covering the main body adhesive portion, and a packaging material arranged on the non-skin surface side of the main body release sheet. The absorbent article package is individually separated by the packaging material by folding the absorbent article, the body release sheet, and the packaging material in an unfolded state in which the absorbent article, the main body release sheet, and the packaging material are laminated, with a plurality of width creases along the width direction as base points. It will be in the packaging state which wrapped the absorbent article. The outer edge in the front-rear direction of the packaging material has a packaging outer edge arranged on the outer surface of the packaging body in the packaging state and a packaging inner edge positioned inside the packaging body in the packaging state. The packaging body has a side joint portion that joins the outer portions of the packaging material in the width direction. The width crease has a first crease and a second crease adjacent to the first crease positioned closer to the outer edge of the package than the first crease in the unfolded state. The first fold and the second fold fold at least the absorbent article and the wrapping material together. The side joint portion has a first side joint portion that joins the packaging materials together in a first folded state folded along the first crease. The packaging material forms a pocket in the first folded state. According to this aspect, the absorbent article can be hygienically discarded using the pocket by taking out the absorbent article while maintaining the joined state of the first side joint portion, that is, while maintaining the shape of the pocket.

According to a preferred aspect, the package has, in the first folded state, an outer region extending from the first fold line to the outer edge of the package, and an inner region extending from the first fold line to the inner edge of the package. The body release sheet and the packaging material are fixed at the fixed portion and are not fixed at the non-fixed portion. The body adhesive portion is provided at least in a first region that is one of the inner region and the outer region. The unfixed portion has a first unfixed portion extending outward in the front-rear direction from the first fold in the first region. The fixed portion has a first fixed portion arranged outside the first non-fixed portion in the front-rear direction in the first region. In the region overlapping with the first non-fixed portion, when a force is applied to pull out the absorbent article to the outside of the pocket, the present release sheet rises from the packaging material, compared to the configuration in which the absorbent article is pulled out without the main release sheet rising. , the absorbent article can be peeled off while reducing the occurrence of shearing stress between the adhesive portion of the main body and the release sheet of the main body. Therefore, the absorbent article can be taken out while maintaining the joint state of the first side joint portion, that is, while maintaining the shape of the pocket. Therefore, the absorbent article can be hygienically disposed of using the pocket.

According to a preferred aspect, the first region is the outer region. A user can remove the absorbent article from the wrapper by pulling the absorbent article in the outer region and the outer packaging edges of the wrapper away from each other. According to this aspect, since the main body release sheet is fixed to the packaging material side in the region overlapping with the first fixing part, the main body release sheet and the main body adhesive part are easily peeled off in the directions perpendicular to each other. Therefore, it is difficult for shear stress to occur due to the adhesive portion of the main body, and it can be peeled off smoothly. When the user further pulls the absorbent article and attempts to separate the main body adhesive part and the main body release sheet in the region overlapping the first non-fixed part, the main body release sheet is not fixed to the packaging material, so the main body release sheet floats against the packaging material. Since the main body release sheet floats and deforms relative to the packaging material, the main body release sheet deforms flexibly, and the main body release sheet can be peeled off smoothly while suppressing the generation of shear stress between the main body adhesive portion and the main body release sheet. Therefore, the absorbent article can be taken out while maintaining the pocket.

According to a preferred aspect, the distance between the front-rear direction inner edge of the first fixing portion and the first fold line is the distance between the front-rear direction outer edge of the first side joint portion and the first fold line. shorter than distance. The outer edge of the first side joint constitutes the edge of the pocket on the opening side. According to this aspect, since the inner edge of the first fixed portion is positioned inside the pocket, the deformation base point of the main body release sheet in the region overlapping the first non-fixed portion can be provided inside the pocket. Deformation and movement of the main body release sheet inside the pocket are encouraged, and the absorbent article can be taken out while suppressing the generation of shear stress between the main body release sheet and the main body adhesive portion. By smoothly taking out the absorbent article while suppressing the occurrence of shearing stress in the adhesive portion of the main body and the release sheet of the main body, the absorbent article can be taken out while maintaining the pocket.

According to a preferred aspect, the distance between the front-rear outer edge of the first fixing portion and the first fold line is the distance between the front-rear outer edge of the first side joint portion and the first fold line. longer than distance. According to this aspect, the first fixing portion is arranged outside the pocket. When the user pulls the absorbent article and the packaging material away from each other outside the pocket, the main body release sheet can be fixed to the packaging material side via the first fixing part, and the main body adhesive part is attached to the main body release sheet. On the other hand, it can be peeled off in a direction in which the surfaces are perpendicular to each other.

According to a preferred aspect, the distance between the front-rear direction inner edge of the first fixing portion and the first fold line is the distance between the front-rear direction outer edge of the first side joint portion and the first fold line. longer than distance. The first fixed portion serves as a base point when the body release sheet in the region overlapping the first non-fixed portion is lifted. According to this aspect, since the reference point is located outside the first side joint portion, the degree of freedom during deformation of the main body release sheet is increased, and the absorbent article can be pulled out more smoothly.

According to a preferred aspect, the inner region, which is the other of the inner region and the outer region, is provided with the main body adhesive portion and a second fixing portion that constitutes the fixing portion. According to this aspect, the fixing part has the first fixing part and the second fixing part which are arranged with the first fold line therebetween. Therefore, the main release sheet is fixed to the packaging material on both sides of the first fold line. When the absorbent article is pulled out of the pocket, it is possible to prevent the entire body release sheet in the pocket from popping out together with the absorbent article. If the entire body release sheet in the pocket protrudes out of the pocket, the body release sheet may follow the absorbent article too much, making it difficult to separate the absorbent article from the body release sheet. However, according to this aspect, only the absorbent article can be pulled out of the pocket while the body release sheet is fixed in the pocket.

According to a preferred aspect, the distance between the front-rear outer edge of the second fixing portion and the first fold line is equal to the front-rear outer edge of the main body adhesive portion in the inner region and the first fold line. shorter than the distance to According to this aspect, when the main body adhesive part in the inner region is peeled off from the main body release sheet, the main body release sheet can be fixed to the packaging material via the second fixing part, and the main body release sheet can pop out of the pocket. can be suppressed, and it is possible to suppress the absorbent article from being turned over to the outside of the pocket as the main body release sheet pops out. By suppressing the absorbent article from being turned over, when the absorbent article is pulled, the adhesive portion of the main body and the release sheet of the main body can be peeled off in a direction perpendicular to each other, and the occurrence of shear stress can be suppressed. .

According to a preferred aspect, the distance between the front-rear inner edge of the second fixing portion and the first fold is the distance between the front-rear inner edge of the first fixing portion and the first fold. shorter than If the second fixing part is too far from the first fold line, the inner surface of the inner area faces the outside of the pocket via the second fixing part when the body adhesive part is peeled off from the main body release sheet in the inner area. Sometimes I turn over. If the inner surface of the inner region is turned over, the first side joint may unintentionally separate and the shape of the pocket may not be maintained. However, since the second fixing portion is close to the first fold, it is possible to suppress the inner surface of the inner region from being turned outward, and it is easy to maintain the shape of the pocket.

According to a preferred aspect, the first area is the inner area. When the user pulls the outer edge of the absorbent article in the outer region and the outer edge of the packaging material away from each other, the absorbent article is pulled away from the outer region, that is, toward the inner region. be done. After the absorbent article is separated from the outer region, the absorbent article is pulled up (pulled away from the first fold line) with respect to the package in the inner region. When the main body adhesive part is peeled off from the main body release sheet in the inner region, the main body adhesive part and the main body release sheet can be peeled off gradually from the first crease side, and the main body adhesive part and the main body release sheet can be peeled off in the direction perpendicular to each other. It is possible to suppress the generation of shear stress between the adhesive portion of the main body and the release sheet of the main body. At this time, since the first non-fixed portion is provided so as to overlap the first fold, the main body release sheet is lifted and deformed against the packaging material at the first non-fixed portion near the first fold, thereby improving the absorbency. When the article is pulled, it can be peeled off smoothly while further suppressing the generation of shear stress between the adhesive portion and the main release sheet. The absorbent article can be taken out while maintaining the shape of the pocket, and the absorbent article can be hygienically disposed of using the pocket.

According to a preferred aspect, the outer region, which is the other of the inner region and the outer region, is provided with the main body adhesive portion and a second fixing portion that constitutes the fixing portion. According to this aspect, when the main body adhesive portion in the outer region is peeled off from the main body release sheet, in the region overlapping with the second fixing portion, the main body release sheet is fixed to the packaging material side. and the adhesive part of the main body are easy to peel off in the direction in which their surfaces are perpendicular to each other. Therefore, shear stress by the adhesive portion of the main body is less likely to occur, and the peeling can be performed smoothly.

According to a preferred aspect, the non-fixed part has a second non-fixed part arranged between the second fixed part and the first fold in the outer region. According to this aspect, in the region overlapping with the second non-fixed portion, the main body release sheet is lifted and deformed with respect to the packaging material. The absorbent article can be removed smoothly while suppressing the occurrence of , and the absorbent article can be taken out while maintaining the pocket.

According to a preferred aspect, the outer edge of the first fixing portion in the front-rear direction is located inside the outer edge of the first side joint portion. Double the distance between the first side joint portion and the first fixing portion in the width direction is longer than the distance between the first side joint portion and the first fixing portion in the front-rear direction. A region between the first side joint portion and the first fixing portion in the width direction is a region where the body release sheet is not stopped with respect to the packaging material and can move freely. On the other hand, the area between the first side joint portion and the first fixing portion in the front-rear direction is along the direction in which the absorbent article is pulled out, and is unlikely to be a freely movable area. Further, the outer edge of the first side joint portion and the outer edge of the first fixing portion are base points for deformation of the main body release sheet with respect to the packaging material. If the deformation base points are too far apart from each other, a load is applied to the first side joint portion, and the joint state of the first side joint portion may not be maintained. However, since the length of the region (freely movable region) between the first side joint portion and the first fixed portion in the width direction is long, the load applied to the outer edge of the first side joint portion is suppressed, The joint state of the one side joint can be maintained.

According to a preferred aspect, the absorbent article has an extending portion that bulges outward in the width direction from the absorbent core, and an extending adhesive portion for attaching the extending portion to the worn article. The width crease folds at least the absorbent article and the packaging material in a state where the extending portion is folded inward in the width direction. The package has an extending release sheet covering the extending adhesive part. In the first folded state, the extended release sheet is joined to the main body release sheet in the inner region via the extended fixing portion. At least a portion of the extending fixing portion is located outside the pocket. According to this aspect, when the absorbent article is pulled toward the inner region and taken out into the pocket, the extending release sheet can be easily pulled out of the pocket with the extending fixing portion as a base point, and can be extended while maintaining the side joint portion. It becomes easier to pull out the release sheet and the absorbent article out of the pocket.

According to a preferred aspect, the first side joint portion has a high joint portion and a low joint portion having a lower peel strength than the first side joint portion. According to this aspect, the absorbent article can be taken out while maintaining the shape of the pocket by taking out the absorbent article from the packaging material side while maintaining the joined state of the first side joint portion by the high joint portion. .

According to a preferred aspect, at least part of the low joint portion is arranged closer to the opening edge side of the pocket than the high joint portion. According to this aspect, the frontage of the pocket can be widened by separating the low joint portion. In the state where the low joint portion is separated, the main adhesive portion or the absorbent article can be put out of the pocket more than in the state where the low joint portion is kept joined. Therefore, it becomes easy to take out the absorbent article 1 out of the pocket while maintaining the bonding of the high bonding portion. In addition, in the first folded state, the user tries to peel off the low joint first and then peel the high joint. At that time, since the peel strength of the high joint is higher than the peel strength of the low joint, the high joint is not continuously peeled off from the low joint. easy to maintain.

According to a preferred aspect, the length in the width direction of the high joint portion may be longer than the length in the width direction of the low joint portion. According to this aspect, the peel strength of the high joint portion can be set higher than the peel strength of the low joint portion.

According to a preferred aspect, the high joint portion joins the packaging materials together by adhesive and welding. The low joint portion joins the packaging materials together only by welding. According to this aspect, the peel strength of the high joint portion can be set higher than the peel strength of the low joint portion.

According to a preferred aspect, the high joint portion and the low joint portion join the packaging materials together with at least an adhesive. The basis weight of the adhesive in the high bond is higher than the basis weight of the adhesive in the low bond. According to this aspect, the peel strength of the high joint portion can be set higher than the peel strength of the low joint portion.

According to a preferred aspect, the high joint portion and the low joint portion join the packaging materials together by welding. The welded area, which is the ratio of the area of the welded portion to the total area of the high joint, is higher than the welded area, which is the ratio of the area of the welded portion to the total area of the low joint. According to this aspect, the peel strength of the high joint portion can be set higher than the peel strength of the low joint portion.

According to a preferred aspect, in the packaging state, the outer portion of the packaging material includes a multi-laminated portion having the largest number of packaging materials, and a small-laminated portion having a smaller number of packaging materials than the multi-laminated portion, have The high joint portion is arranged in the multi-laminate portion. According to this aspect, it is possible to prevent the pocket from being damaged when the package is unpacked. The pocket can be prevented from being damaged by the force applied when opening.

According to a preferred aspect, the high joint portion is spaced apart from the second fold line and arranged closer to the first fold line than the second fold line. An open end of the pocket with a high joint is provided spaced from the second fold line. Therefore, when the absorbent article is taken out in the first folded state, the absorbent article is absorbed using the crease of the absorbent article due to the second fold line and the outer edge of the high joint portion located away from the second fold line as a base point. The physical article is pulled out while being bent. Since the absorbent article is taken out while being deformed, it is possible to maintain the bonded state of the highly bonded portion of the packaging material, making it easier to maintain the shape of the pocket.

According to a preferred aspect, the fixing part has an outer edge fixing part positioned closest to the outer edge of the package in the first folded state. The distance between the outer edge fixing portion and the outer edge of the package is shorter than the distance between the outer edge of the package and the outer edge of the main body adhesive portion in the front-rear direction. According to this aspect, since the outer edge fixing portion is positioned closer to the package outer edge 71 than the main body adhesive portion, when the packaging material and the absorbent article are pulled from the package outer edge side in a direction to separate them from each other, the main body release sheet is removed from the package. Since it is fixed to the material 70 and does not follow the body adhesive portion of the absorbent article too much, the body adhesive portion can be smoothly peeled off from the body release sheet.

According to a preferred aspect, a body release sheet is provided between the absorbent article and the packaging material to cover the body adhesive part. At least one of the packaging material and the main body release sheet is provided with a pocket display part reminiscent of the pocket. By providing the pocket display portion, it becomes easier for the user to recognize the function of the pocket.

According to a preferred aspect, the edge in the front-rear direction of the packaging material located outside the package in the packaged state overlaps the pocket display portion. According to this aspect, the pocket display portion is divided by the front-back direction edge (packaging outer edge) of the packaging material, and the pocket display portion becomes more conspicuous. Therefore, it becomes easier for the user to recognize the pocket display portion and grasp the existence of the pocket.

According to a preferred aspect, at least part of the pocket display part is arranged on the outer surface of the package in the package state. According to this aspect, since the pocket display portion is arranged on the outer surface in the wrapped state, the user can easily recognize the pocket display portion in the wrapped state and grasp the presence of the pocket.

A method for manufacturing a package according to one aspect includes folding an absorbent article and a packaging material at least around a first fold line and a second fold line along the width direction, and individually wrapping the absorbent article with the wrapping material. Manufacture a package of absorbent articles to be used. The manufacturing method includes a first joining step of folding the packaging material and the absorbent article with the first crease as a base point, joining the outer sides of the folded packaging material in the width direction, and providing a first side joint. and, after the first joining step, folding the packaging material and the absorbent article with at least the second crease as a base point, and joining the outer sides of the folded packaging material in the width direction to form a second side joining. and a second joining step of providing a portion. According to this aspect, since the first side joint is provided and then the second side joint is provided, the peel strength of the first side joint and the peel strength of the second side joint can be made different.

In the form in which the fixing portion is arranged in the region overlapping the first fold line F1, it is preferable that the fixing portion does not straddle the first fold line F1. This is because if the fixing portion is arranged across the first fold line F1, an inflection point is formed at the first fold line F1 as a boundary at which force is applied at the time of unsealing. In addition, in the form having no main body release sheet, the main body adhesive portion 6 is not provided in the region overlapping the first fold line F1, and is configured so that the absorbent article 1 is lifted from the packaging material 70 in the region overlapping the first fold line F1. may be In another form that does not have a main body release sheet, the main body adhesive part 6 may be fixed to the packaging material 70 in the region overlapping the first fold line F1. That is, in a modified example, the region of the packaging material 70 that overlaps the first fold line F1 may be configured to follow the main body adhesive portion 6 when the absorbent article 1 is taken out.

The package 101 is a package in which at least the absorbent article 1 and the packaging material 70 are individually wrapped with the packaging material 70 by folding the absorbent article 1 and the packaging material 70 from the unfolded state with a plurality of width creases along the width direction W as base points. state. As shown in FIG. 1, the package 101 in the "unfolded state" means that the package 101 in the unfolded state is unsealed, and the folded portions of the packaging material 70 and the absorbent article 1 are unfolded with respect to the width crease. It refers to the state in which possible parts are expanded. As shown in FIG. 3, the package 101 in the "wrapped state" means a predetermined portion of the package 101 in the unfolded state, specifically, with the top sheet 2 inside at the first fold line F1 and the second fold line F2. It means a state in which the packaging material 70 is folded by itself and sealed by forming the side joints 60 where the outer portions, which are the ends in the width direction W of the packaging material 70, are joined. At least the packaging material 70 may be folded at the width crease, and the packaging material 70, the body release sheet 50 and the absorbent article 1 may be folded together. In a configuration in which only the packaging material 70 or only the packaging material 70 and the main body release sheet 50 are folded at the width crease, the absorbent article 1 may not be folded, or the absorbent article 1 may be folded alone. It may be folded with a crease separated from the crease (for example, a crease positioned inside in the front-rear direction in the wrapped state relative to the width crease) as a base point.

The width crease has at least a first crease F1 and a second crease F2. The first fold line F1 is positioned closer to the package inner edge 72 than the second fold line F2 in the unfolded state. The second fold line F2 is a fold line adjacent to the first fold line F1 in the unfolded state, and is positioned closer to the package outer edge 71 than the first fold line F1. The first fold line F1 and the second fold line F2 are spaced apart in the front-rear direction L. In the unfolded state, the first fold line F1 and the second fold line F2 are adjacent to each other, and no other width crease is arranged between the first fold line F1 and the second fold line F2. The first fold line F1 may be positioned closest to the inner edge 72 of the width fold line, or another width fold line may be positioned between the first fold line F1 and the inner edge 72 of the package. That is, the first fold line F1 may be the fold line that is folded first in the unfolded state, or may be the fold line that is folded next after being folded around another width crease in the unfolded state. In a mode in which another width crease is arranged between the first fold F1 and the packaging inner edge 72, in the packaging state, the packaging inner edge 72 folded by the other width crease is aligned with a first side joint portion 61 to be described later. does not overlap with That is, in the mode in which the other width crease is arranged between the first fold line F1 and the package inner edge 72, the package inner edge 72 is positioned outside the pocket, which will be described later, in the first folded state. In addition, the second fold line F2 may be positioned closest to the outer edge 71 of the width fold line, or another width fold line may be positioned between the second fold line F2 and the outer edge 71 of the package. The other width crease may be one or plural.

The package 101 of the first embodiment is first folded around the first fold line F1 and then folded around the second fold line F2 in order to switch from the unfolded state shown in FIG. 1 to the wrapped state. . When unfolding from the wrapped state to the unfolded state, the user unfolds in order from the width crease located on the package outer edge 71 side to the width crease located on the package inner edge 72 side. Note that the first fold line F1 and the second fold line F2 are not "lines" but "areas" having a certain area. As shown in FIG. 4 and the like, in the first folded state in which the package 101 is folded along the first fold line F1, the outer region R10 extends from the first fold line F1 to the package outer edge 71, and the package inner edge 72 extends from the first fold line F1. and an inner region R20 extending to the

The first folding state is the state shown in FIG. 4, in which the first folding line F1 is folded, and the width folding line (in the present embodiment, the second folding line F2) located closer to the package outer edge 71 than the first folding line F1. It is in a state where it is not In a mode in which another width fold is arranged between the first fold F1 and the inner edge 72 of the package, the first folded state is the other width fold located between the first fold F1 and the inner edge 72 of the package. and the first folding line F1. That is, the first folded state includes the first fold line F1 and is folded from the width fold line located closer to the package inner edge 72 than the first fold line F1, and the outer region is closer to the package outer edge 71 side than the first fold line F1. R10 is unfolded (outer region R10 is not folded).

The side joint portion 60 is a joint portion that joins the outer portions of the packaging material 70 in a state where the packaging material 70 is folded with the width crease as the base point. The side joint portion 60 includes a first side joint portion 61 that joins the packaging material 70 in the first folded state folded along the first fold line F1, and a first side joint portion 61 that joins the packaging material 70 together in the second folded state folded along the second fold line F2. and a second side joint portion 62 that joins them together. Note that the second folded state of the present embodiment is the wrapped state. In the modified example, in the form having the third fold line located closer to the package outer edge 71 than the second fold line F2, the third folded state in which the third fold line F3 is the base point in the second folded state is the third folded state. , may be in a packaged state. By unfolding from the wrapped state (in this embodiment, the second folded state) to the first folded state, a part of the second side joint portion 62 remains, and the remaining portion constitutes the first side joint portion 61. You can The first side joint portion 61 may have regions with different peel strengths. More specifically, the first side joint portion 61 may have a high joint portion 611 and a low joint portion 612 having a lower peel strength than the high joint portion 611 .

The packaging body 101 of the first embodiment is configured so that a pocket P is provided in the packaging material 70 in the process of taking out the absorbent article 1 so that the absorbent article 1 can be hygienically discarded. Next, the configuration for forming the pocket P in the packaging material 70 will be described in detail. When the user takes out the absorbent article 1, the user unfolds the package 101 in the wrapped state to the unfolded state, removes the absorbent article 1 from the main release sheet 50 and the packaging material 70, or removes the package 101 in the wrapped state. is partially unfolded, and the absorbent article 1 is removed from the body release sheet 50 and the packaging material 70 in the first folded state. The packaging body 101 of the first embodiment is configured such that a pocket P can be formed by the packaging material 70 when removing the absorbent article 1 in the first folded state.

The pocket P has a storage space sandwiched between the inner region R20 and the outer region R10 in the first folded state. The inner region R20 and the outer region R10 are joined by a first side joint portion 61 in the first folded state. The first side joint portion 61 may be provided throughout the front-rear direction L of the region (R25 shown in FIG. 4) where the outer region R10 and the inner region R20 overlap in the first folded state. It may be provided in a part of the region R25 in the front-rear direction L where the region R20 overlaps. The first side joint portion 61 of the first embodiment is provided over the entire area in the front-rear direction L of the region R25. More specifically, the first side joint portion 61 includes a low joint portion 612 extending from the package inner edge 72 toward the first fold line F1, a high joint portion 611 positioned closer to the first fold line F1 than the low joint portion 612, have The outer edge of the accommodation space of the pocket P is the inner edge 61I of the first side joint portion 61 . The inner edge of the pocket P (inner edge in the front-rear direction) is the first fold line F1. The outer edge (opening edge) of the pocket P may be the outer edge (the edge opposite to the first fold line F1) 61S of the first side joint portion 61, or the outer edge of the first side joint portion 61. It may be spaced apart from the edge 61S and positioned closer to the first fold line F1 than the outer edge 61S of the first side joint portion 61 . Specifically, in the form having the high joint portion 611 and the low joint portion 612, the outer edge 611S of the high joint portion 611 may constitute the opening edge of the pocket P.

In a package that does not have a pocket P, even if the folded or rolled absorbent article 1 is covered with the wrapping material 70 at the time of disposal of the absorbent article, the width direction W of the absorbent article 1 does not change. Since it is difficult to cover the end of the absorbent article 1, the excretion of the used absorbent article 1 becomes visible, and the user may be worried about leakage of the excrement and odor to the outside. In particular, when the used absorbent article 1 cannot be discarded immediately, it is necessary to carry it around in a bag or the like. rice field. On the other hand, in the packaging body 101 of the present embodiment, the packaging material 70 has the pocket P. As shown in FIG. The pocket P is a bag-like portion for putting the used absorbent article 1 therein. FIG. 5 is a diagram explaining how to use the pocket. As shown in FIG. 5, the used absorbent article 1 can be appropriately folded or rolled up and placed in the pocket P, so that the entire used absorbent article 1 can be easily covered with the wrapping material 70. . By covering the whole area of the used absorbent article 1 with the packaging material 70, the excrement can be made invisible from the outside, and the fear of leakage of excrement and odor from the used absorbent article 1 can be reduced. can be done. As a result, when the used absorbent article 1 is carried around, it is possible to reduce fears of excrement leakage and odor, and to hide the used absorbent article 1, especially excrement, from the outside. Therefore, it can be discarded in a preferable state from the viewpoint of etiquette.

When the user takes out the absorbent article 1 in the first folded state, the packaging body 101 holds the absorbent article while forming the pocket P in the packaging material 70 (while maintaining the joint by the first side joint portion 61). 1 can be taken out. That is, the packaging material 70 forms a pocket P sandwiched between the pair of first side joints 61 in the first folded state. The pocket P may be formed in a state in which the joint state of the entire first side joint portion 61 is maintained, or may be formed in a state in which the joint state of a part of the first side joint portion 61 is maintained. may Specifically, the peel strength of the first side joint portion 61 when unfolding from the first folded state is higher than the peel strength of the second side joint portion 62 when unfolding from the second folded state to the first folded state. expensive. Since the peel strength of the first side joint portion 61 is higher than the peel strength of the second side joint portion 62, the user peels off the packaging material 70 when unfolding from the second folded state to the first folded state. Even if an attempt is made to unfold the first folded state with a force similar to that of the time, the joined state of the first side joint portion 61 can be maintained. By taking out the absorbent article 1 from the packaging material 70 side while maintaining the joined state of the first side joint portion 61, the absorbent article 1 can be taken out while maintaining the shape of the pocket P. Therefore, the absorbent article 1 can be hygienically discarded using the pocket P.

It is sufficient that the peel strength of at least a part of the first side joint portion 61 is higher than the peel strength of the second side joint portion 62 , and the peel strength of the entire first side joint portion 61 is equal to that of the second side joint portion 62 . It may be higher than the peel strength. The high joint portion 611 has a higher peel strength than the second side joint portion 62 and may constitute the opening edge of the pocket P. In this embodiment, the peel strength of the low joint portion 612 may be lower than the peel strength of the second side joint portion 62 . According to this embodiment, the shape of the pocket P is maintained by removing the absorbent article 1 from the packaging material 70 side while maintaining the joined state of the first side joints 61 by the high joints 611. 1 can be taken out. The peel strength of the first side joint portion 61 may be 1.5 times or more the peel strength of the second side joint portion 62 . In addition, the peel strength of the high joint portion 611 may be higher than the peel strength of the low joint portion 612, but is preferably 1.5 times or more the peel strength of the low joint portion 612. It may be 1.5 or more relative to the peel strength of the joint 62 . The peel strength of each joint can be measured by a well-known method.

The means for differentiating the peel strength of the first side joint portion 61 and the peel strength of the second side joint portion 62 is not particularly limited. For example, the method for manufacturing a package having such a configuration involves folding the packaging material 70 and the absorbent article 1 with the first fold line F1 as the width fold line as a base point, and folding the outer portions of the folded packaging material 70 in the width direction W to each other. After the first joining step of joining and providing the first side joint portion 61, and after the first joining step, the packaging material 70 and the absorbent article 1 are folded at least around the second fold line F2 to form a packaged state, and the packaging material is folded. and a second joining step of joining the widthwise outer portions to provide a second side joint portion 62 . According to this aspect, since the second side joint portion 62 is provided after the first side joint portion 61 is provided, the peel strength of the first side joint portion 61 and the peel strength of the second side joint portion 62 can be made different. , and the peel strength of the first side joint portion 61 can be made higher than the peel strength of the second side joint portion 62 . In addition, since the step of joining the packaging materials 70 is performed in two stages, and the packaging materials 70 are joined in a stage prior to the packaging state, compared to a form in which side joints are not provided before the packaging state. , it is possible to stably convey the package (the package in the middle of production) in the previous process to be in the packaging state. In particular, in the case of high-speed manufacturing, it is possible to prevent the wrapping material 70 from being turned over, and to stably manufacture the product. Also, in the second joining step, a second side joint portion 62 may be provided in a region overlapping with the first side joint portion 61 . In the region where the first side joint portion 61 and the second side joint portion 62 overlap in the thickness direction, the packaging materials 70 are joined together in both the first joining step and the second joining step, so the peel strength should be increased. can be done. note that. The bonding means in the first bonding step and the bonding means in the second bonding step may be the same or different. Specifically, both the first bonding step and the second bonding step may be bonding by welding, both may be bonding by adhesive, or one may be bonding by adhesive and the other may be bonding by adhesive. may be joined by welding. In this embodiment, the first side bonding step is bonding with an adhesive, and the second side bonding step is bonding by welding.

At least part of the low joint portion 612 may be arranged closer to the opening edge side of the pocket P than the high joint portion 611 is. According to this aspect, the frontage of the pocket P can be widened by opening the low joint portion 612 . The main body adhesive portion 6 or the absorbent article 1 can be taken out of the pocket P compared to the state where the low joint portion 612 is kept joined. Therefore, it becomes easy to take out the absorbent article 1 out of the pocket P while maintaining the bonding of the high bonding portion 611 . In addition, in the first folded state, the user first peels off the low joint portion 612 and then tries to peel off the high joint portion 611 . At this time, since the peel strength of the high bonding portion 611 is relatively high, the bonding state of the high bonding portion 611 can be maintained without continuously peeling the high bonding portion 611 to the low bonding portion 612 . In the configuration in which the packaging material 70 is folded in the region between the first fold line F1 and the inner packaging edge 72 , the folded packaging material 70 between the first fold line F1 and the inner packaging edge 72 overlaps the low joint 612 . However, it is preferable not to overlap with the high joint portion 611 . If the folded packaging material 70 overlaps the high joint portion 611 between the first fold line F1 and the package inner edge 72, the folded packaging material 70 can be unfolded while the high joint portion 611 is kept joined. There is a risk that the absorbent article cannot be taken out smoothly. However, since the folded packaging material 70 does not overlap the high joint portion 611 , the folded packaging material 70 can be unfolded between the first fold line F1 and the package inner edge 72 by peeling the low joint portion 612 . Further, in a modified example, the low joint portion 612 may be provided closer to the first fold line F1 than the high joint portion 611 is. The high joint portions 611 and the low joint portions 612 may be alternately arranged in the front-rear direction L. The user can easily feel the difference between the peel strength of the high joint portion 611 and the peel strength of the low joint portion 612 . Further, in the first side joint portion 61 , the length of the high joint portion 611 in the front-rear direction may be longer than the length of the low joint portion 612 in the front-rear direction L.

FIG. When the user takes out the absorbent article 1 from the package in the wrapped state, the outer edge 71 of the packaging material 70 and the absorbent article 1 are both unfolded to be in the first folded state shown in FIG. In the present embodiment, with the second fold line F2 as a base point, the packaging outer edge 71 of the packaging material 70 and the absorbent article 1 are both unfolded into the first folded state shown in FIG. As shown in FIG. 4 and the like, in the first folded state, they are joined via the first side joint portion 61, and a pocket P is formed by the outer region R10 and the inner region R20. The packaging material 70, the body release sheet 50 and the absorbent article 1 are all folded at the first fold line F1, and the absorbent article 1 folded at the first fold line F1 is accommodated inside the pocket P. In general, when the user takes out the absorbent article 1 in the first folded state, the user grips the vicinity of the package outer edge 71 of the outer region R10 to perform the operation.

As shown in FIGS. 6(a) and (d), the user grips the absorbent article 1 in the outer region R10 with one hand, and grips the packaging material 70 in the outer region R10 with the other hand to wrap. In an attempt to remove the absorbent article 1 from the material 70, the wrapping material 70 and the absorbent article 1 are pulled away from each other. 6(a) and (d) show a state in which the front end of the absorbent article 1 and the outer edge 71 of the package have begun to separate by pulling the packaging material 70 and the absorbent article 1 away from each other. At this time, in order to separate the absorbent article 1 from the packaging material 70 side, it is necessary to either join the packaging material 70 and the main release sheet 50 together, or hold the main release sheet 50 and the packaging material 70 together with the other hand. be. In this embodiment, an outer edge fixing portion 95 is provided. In the region closer to the packaging outer edge 71 than the first fixing part 91, the outer edge fixing part 95 joins the packaging material 70 and the body release sheet 50, and pulling the absorbent article 1 and the packaging material 70 away from each other allows the absorption The body adhesive portion 6 of the physical article 1 can be peeled off from the body release sheet 50 .

When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the packaging material 70 and the body release sheet 50 are further separated from the absorbent article 1 . The main body release sheet 50 is joined to the packaging material 70 via the first fixing portion 91 in the region overlapping the first fixing portion 91 . Therefore, by pulling the packaging material 70 and the absorbent article 1 away from each other, the absorbent article 1 is peeled off from the body peeling sheet 50 . At this time, in the region overlapping with the first fixing portion 91, the surfaces are peeled off in the direction perpendicular to each other, and the shear stress due to the main body adhesive portion 6 is less likely to occur, and the peeling can be performed smoothly. It should be noted that even in a configuration without the outer edge fixing portion 95, in the region overlapping with the first fixing portion 91, by pulling the absorbent article 1 and the packaging material 70 in directions away from each other, the main body adhesive portion of the absorbent article 1 is removed. 6 can be peeled off from the body peeling sheet 50 . In addition, the wing release sheet 52 is fixed to the packaging material 70 in the inner region R20 via the wing fixing portion 97, and gradually separates from the wing adhesive portion 7 as the inner region R20 and the outer region R10 are separated from each other. Part 7 is exposed.

When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the states shown in FIGS. 6(b) and (e) are obtained. 6B and 6E show a state in which the absorbent article 1 is separated from the packaging material 70 and the body release sheet 50 up to the region overlapping the first non-fixed portion 81. FIG. The body release sheet 50 is not bonded to the packaging material 70 in the region overlapping the first non-fixed portion 81 . Therefore, when the packaging material 70 and the absorbent article 1 are pulled away from each other, the body release sheet 50 follows the body adhesive part 6 of the absorbent article 1 and separates from the packaging material 70 . The absorbent article 1 and the packaging material 70 of the inner region R20 are deformed with the outer edge 61S of the first side joint portion 61 as a base point. Therefore, force due to deformation of the absorbent article 1 is applied to the outer edge 61S of the first side joint portion 61 . At this time, the low joint portion 612 may be peeled off, and the shape of the pocket P can be maintained by maintaining the joint state of the high joint portion 611 .

When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the states shown in FIGS. 6(c) and (f) are obtained. 6(c) and (f) show the state in which the absorbent article 1 and the packaging material 70 have been separated in the outer region R10, and then the absorbent article 1 and the packaging material 70 have been separated in the inner region R20. . The main release sheet 50 is separated from the packaging material 70 over the entire region overlapping the first non-fixed portion 81 , and the main release sheet 50 moves to the vicinity of the opening of the pocket P or outside the pocket P. Therefore, when the absorbent article 1 is pulled against the packaging material 70 , the absorbent article 1 is separated from the body release sheet 50 . At this time, the body release sheet 50 is joined to the packaging material 70 in the outer region R10 via the first fixing portion 91, and by pulling the absorbent article 1 in the inner region R20 away from the outer region R10, The main body adhesive part 6 and the main body release sheet 50 are peeled off in a direction perpendicular to each other, so that shear stress by the main body adhesive part 6 is less likely to occur, and smooth peeling can be performed. At this time, since the peel strength of the first side joint portion 61 is configured to be high, the joint state of the first side joint portion 61 can be easily maintained. The absorbent article 1 can be taken out while maintaining the shape of the pocket P, and the absorbent article 1 can be hygienically discarded using the pocket P.

In the modified example, in the form without the main body release sheet, the packaging material 70 follows the main body adhesive part 6 in the area overlapping the main body adhesive part 6, and the packaging material 70 in the area not overlapping the main body adhesive part 6. does not follow the body adhesive part 6. Therefore, in the first folded state, when the main body adhesive portion 6 is arranged in a region that does not overlap with the first fold line F1, the first fold line is folded in the same manner as in the state where the first non-fixed portion 81 and the first fold line F1 overlap each other. The absorbent article 1 floats on the packaging material 70 of F1. On the other hand, in the first folded state, when the main body adhesive part 6 is arranged in the region overlapping the first fold line F1, the absorbent article 1 does not rise from the packaging material 70 at the first fold line F1, and the packaging material 70 does not rise. The first fold line F1 portion is deformed, and the load on the outer edge 61S of the first side joint portion 61 is increased. However, since the peel strength of the first side joint portion 61 is higher than the peel strength of the second side joint portion 62, the joint state of the first side joint portion 61 can be maintained.

The length in the front-rear direction L of the first side joint portion 61 may be three times or more the maximum thickness of the absorbent article before use. Preferably, the length in the front-rear direction L of the high joint portion 611 is It may be three times or more the maximum thickness of the absorbent article before use.

FIG. The main body release sheet 50 is joined to the packaging material 70 via the first fixing portion 91 in the region overlapping the first fixing portion 91 . Therefore, by pulling the packaging material 70 and the absorbent article 1 away from each other, the absorbent article 1 is peeled off from the body peeling sheet 50 . At this time, in the region overlapping with the first fixing portion 91, the surfaces are peeled off in the directions perpendicular to each other, and shear stress by the main body adhesive portion 6 is less likely to occur, and the peeling can be performed smoothly.

When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the states shown in FIGS. 7(c) and (g) are obtained. 7(c) and (g) show a state in which the absorbent article 1 is separated from the packaging material 70 and the body release sheet 50 up to the region overlapping the first non-fixed portion 81. FIG. The body release sheet 50 is not bonded to the packaging material 70 in the region overlapping the first non-fixed portion 81 . Therefore, when the packaging material 70 and the absorbent article 1 are pulled away from each other, the body release sheet 50 follows the body adhesive portion 6 of the absorbent article 1 and separates from the packaging material 70 . The absorbent article 1 and the packaging material 70 of the inner region R20 are deformed with the outer edge 61S of the first side joint portion 61 as a base point. Therefore, force due to deformation of the absorbent article 1 is applied to the outer edge 61S of the first side joint portion 61 .

When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the states shown in FIGS. 7(d) and (h) are obtained. 7(d) and (h) show the state in which the absorbent article 1 and the packaging material 70 have been separated in the outer region R10, and then the absorbent article 1 and the packaging material 70 have been separated in the inner region R20. . The body release sheet 50 is separated from the packaging material 70 over the entire region overlapping the first non-fixed portion 81, and the body release sheet 50 moves to the vicinity of the opening of the pocket P or outside the pocket. Therefore, when the absorbent article 1 is pulled against the packaging material 70 , the absorbent article 1 is separated from the body release sheet 50 . At this time, the body release sheet 50 is joined to the packaging material 70 in the outer region R10 via the first fixing portion 91, and by pulling the absorbent article 1 in the inner region R20 away from the outer region R10, The main body adhesive part 6 and the main body release sheet 50 are peeled off in a direction perpendicular to each other, so that shear stress by the main body adhesive part 6 is less likely to occur, and smooth peeling can be performed.

If the first non-fixed portion 81 is not formed, i.e., the fixed portion 90 is provided at the first fold line F1, when the absorbent article 1 in the pocket P in the first folded state is pulled, the first The main body release sheet 50 does not rise from the packaging material 70 at the fold line F1, and the main body release sheet 50 does not rise from the packaging material 70 in the pocket P. - 特許庁Therefore, a strong shearing stress is generated between the main body adhesive portion 6 and the main body release sheet 50 particularly in the vicinity of the first fold line F1, and it is possible to take out the absorbent article 1 while maintaining the bonded state of the first side joint portions 61. Sometimes I can't.

On the other hand, the package 102 according to the second embodiment is provided with the first non-fixed portion 81 overlapping the first fold line F1. In the region overlapping with the first non-fixed portion 81, the main body release sheet 50 is lifted and deformed with respect to the packaging material 70. Therefore, the main body release sheet 50 does not lift up and the absorbent article 1 is pulled out. The generation of shear stress between the portion 6 and the main release sheet 50 can be suppressed, and a peel stress is generated in which the surfaces are peeled off in directions perpendicular to each other. The peel stress is smaller than the shear stress when the adhesive portions of the same area are peeled off. Therefore, the absorbent article 1 can be taken out while maintaining the pocket P by smoothly peeling the body adhesive portion 6 and the body release sheet 50 while suppressing the generation of shear stress. If a strong shearing stress is generated in the main body adhesive portion 6, the force to take out the absorbent article 1 becomes stronger, the force applied to the outer edge 61S of the first side joint portion 61 also becomes stronger, and the first side joint portion 61 is joined. The state may not be maintained. However, by removing the absorbent article 1 while reducing the shearing stress of the main body adhesive portion 6, the bonded state of the first side bonding portion 61 can be maintained. The absorbent article 1 can be taken out while maintaining the shape of the pocket P, and the absorbent article 1 can be hygienically discarded using the pocket P.

As shown in FIG. Inside the pocket P, the main body release sheet 50 itself can be deformed and the main body release sheet 50 can be moved with respect to the packaging material 70, thereby suppressing the generation of shear stress between the main body release sheet 50 and the main body adhesive portion 6 while absorbing. The sexual article 1 can be taken out. It is possible to take out the absorbent article 1 while maintaining the pocket P by smoothly taking out the absorbent article 1 while suppressing the occurrence of shearing stress on the main body adhesive portion 6 and the main body release sheet 50 .

A distance L21 along the front-rear direction L between the outer edge 91S of the first fixing portion 91 and the first fold line F1 is defined by may be shorter than the distance L12. According to this aspect, since the first fixing portion 91 is located inside the front-rear direction L (first fold line F1 side) of the outer edge 61S of the first fixing portion 91, after the absorbent article 1 is taken out, The main body release sheet 50 is easily maintained inside the pocket, and the waste after use is easily accommodated in the pocket P.

In the modified example, the distance L12 along the front-rear direction L between the outer edge 91S of the first fixing portion 91 and the first fold line F1 is the distance between the outer edge 61S of the first side joint portion 61 and the first fold line F1. It may be longer than the distance L21 along the direction L. According to this aspect, the first fixing portion 91 is arranged outside the pocket P. As shown in FIG. When the user pulls the absorbent article 1 and the packaging material 70 away from each other outside the pocket P, the main body release sheet 50 can be fixed to the packaging material 70 via the first fixing part 91, and the main body The adhesive portion 6 can be peeled off from the main body peeling sheet 50 in the directions perpendicular to each other. Preferably, the first fixing portion 91 may be arranged across the outer edge 61S of the first side joint portion 61 in the front-rear direction L. As shown in FIG. According to a preferred configuration, by continuing to pull the absorbent article 1 and the packaging material 70 from the area outside the pocket P toward the area inside the pocket P, the surfaces of the absorbent article 1 and the packaging material 70 continue to be peeled off in the direction perpendicular to each other. , while suppressing the generation of shear stress inside the pocket P, the absorbent article 1 can be easily peeled off.

In the modified example, the distance L11 along the front-rear direction L between the inner edge 91V of the first fixing portion 91 and the first fold line F1 is the distance between the outer edge 61S of the first side joint portion 61 and the first fold line F1. It may be longer than the distance L12 along the direction L. That is, the inner edge 91V of the first fixing portion 91 may be positioned outside the pocket P. According to the modification, the body release sheet 50 in the region overlapping the first non-fixed portion 81 is lifted up, and the starting point is positioned outside the pocket P. As shown in FIG. Therefore, the degree of freedom during deformation of the body release sheet 50 is increased, and the absorbent article 1 can be pulled out smoothly.

The body adhesive portion 6 may also be provided in the inner region R20. The main body adhesive portion 6 of the inner region R20 may be continuous with the main body adhesive portion 6 of the outer region R10, or may be separated from the main body adhesive portion 6 of the outer region R10. Further, the body adhesive portion 6 of the first embodiment is arranged in the region overlapping the first fold line F1, but in the modified example, it may not be arranged in the region overlapping the first fold line F1. In addition, the outer edge of the main body adhesive portion 6 in the inner region R20 is the outer edge of the main body adhesive portion 6 farthest from the first fold line F1 among the main body adhesive portions 6 in the inner region R20, and the main body of the inner region R20 This is the end edge of the adhesive portion 6 that is positioned closest to the inner edge 72 of the package.

The fixing part 90 may have a second fixing part 92 provided in the inner region R20. That is, the fixing portion 90 may have a first fixing portion 91 and a second fixing portion 92 that are arranged with the first fold line F1 interposed therebetween. According to this aspect, the main release sheet 50 is fixed to the packaging material 70 on both sides of the first fold line F1. When the absorbent article 1 is pulled out of the pocket P, it is possible to prevent the entire body release sheet 50 in the pocket P from popping out together with the absorbent article 1 . If the entire body release sheet 50 in the pocket pops out of the pocket P, the body release sheet 50 follows the absorbent article 1 too much, making it difficult to smoothly release the absorbent article 1 from the body release sheet 50. can be. However, according to this aspect, only the absorbent article 1 can be pulled out of the pocket P while the main body release sheet 50 is fixed in the pocket P, and the main body adhesive portion 6 and the main body release sheet 50 are perpendicular to each other. It becomes easier to peel off in the direction of Also, the first fixed portion 91 and the second fixed portion 92 serve as deformation base points of the main body release sheet 50 in the region overlapping the first non-fixed portion 81 . Since the deformation base points are located on both sides in the front-rear direction L across the first fold line F1, excessive movement of the main body release sheet 50 is suppressed, and the main body adhesive part 6 is smoothly peeled off from the main body release sheet 50. can be done.

A distance L31 along the front-rear direction L between the outer edge 92S of the second fixing portion 92 and the first fold line F1 is the distance L between the outer edge 6S2 of the main body adhesive portion 6 and the first fold line F1 in the inner region R20. may be shorter than the distance L32 along the . The outer edge of the second fixing portion 92 in the front-rear direction is the edge of the front-rear direction edge of the second fixing portion 92 opposite to the first fold line F1. The outer edge 92</b>S of the second fixing portion 92 is positioned closer to the first fold line F<b>1 than the outer edge 6</b>S<b>2 of the main body adhesive portion 6 in the front-rear direction L. When the main body adhesive part 6 of the inner region R20 is peeled off from the main body release sheet 50, the main body release sheet 50 can be fixed to the packaging material 70 via the second fixing part, and the main body release sheet 50 pops out of the pocket P. can be suppressed, and the absorbent article 1 can be suppressed from being turned over to the outside of the pocket P as the body release sheet 50 pops out. By suppressing the absorbent article 1 from being turned over, when the absorbent article 1 is pulled, the surfaces of the main body adhesive portion 6 and the main body release sheet 50 can be separated in the directions orthogonal to each other. , the generation of shear stress can be suppressed. In addition, in the modified example, the second fixing portion 92 may not be provided, or the second fixing portion 92 may be provided only outside the pocket.

A distance L41 along the front-rear direction L between the inner edge 92V of the second fixing portion 92 and the first fold line F1 is a distance L41 along the front-rear direction L between the inner edge 91V of the first fixing portion 91 and the first fold line F1. It may be shorter than the distance L11. The inner edge 92V of the second fixing portion 92 is the edge on the first fold line F1 side among the edges of the second fixing portion 92 in the front-rear direction. Since the second fixing portion 92 is closer to the first fold line F1 than the first fixing portion 91, when the main body adhesive portion 6 is peeled off from the main body release sheet 50 in the outer region R10, the second fixing portion 92 This suppresses the main body release sheet 50 from being lifted up, and makes it easier to keep peeling the main body release sheet 50 and the main body adhesive portion 6 in the directions perpendicular to each other in the outer region R10. Also, if the second fixing portion 92 is too far from the first fold line F1, when the main body adhesive portion 6 is to be peeled off from the main body release sheet 50 in the inner region R20, the inner surface of the inner region R20 will be stuck to the second fixing portion. With 92 as a base point, it may be turned over to the outside of the pocket P. If the inner surface of the inner region R20 is turned over, the first side joint portion 61 may be unintentionally separated and the shape of the pocket P may not be maintained. However, since the second fixing portion 92 is close to the first fold line F1, it is possible to suppress the inner surface of the inner region R20 from being turned outward, and the shape of the pocket P can be easily maintained.

More preferably, the distance L41 between the inner edge 92V of the second fixing portion 92 and the first fold line F1 is 1/2 or less of the distance between the outer edge 61S of the first side joint portion 61 and the first fold line F1. can be According to this configuration, the second fixing portion 92 can be arranged in the vicinity of the first fold line F1, which is the bottom portion of the pocket P. As shown in FIG. Preferably, the distance L41 between the inner edge 92V of the second fixing portion 92 and the first fold line F1 is 1/2 of the distance L11 between the inner edge 91V of the first fixing portion 91 and the first fold line F1. may be: According to this configuration, it is easier to obtain the effect of suppressing the main body release sheet 50 from popping out to the pocket side and the effect of suppressing the inner region R20 from being turned up outside the pocket on the inner surface side by the second fixing portion 92 . That is, it is preferable that the second fixing portion 92 is close to the first fold line F1. However, it is preferable that the second fixing portion 92 does not overlap the first fold line F1 in order to obtain the effect that the main body release sheet 50 is lifted from the packaging material 70 at the first fold line F1. A distance L41 between the first fold line F1 and the second fixing portion 92 may be 10 mm or less, more preferably 5 mm or less. By extending the second fixing portion 92 to the vicinity of the first fold line F1, the length by which the main body release sheet 50 is lifted in the inner region R20 can be shortened. Therefore, when peeling off the main body adhesive part 6 from the main body release sheet 50 in the outer region R10, by performing an operation of pulling the absorbent article 1 toward the inner region R20 side, the main body adhesive part 6 and the main body release sheet are separated. 50 can be peeled off while reducing the shear stress.

The outer edge fixing portion 95 may be located closer to the package outer edge 71 than the first fixing portion 91 in the first folded state. When the absorbent article 1 and the packaging material 70 are pulled away from each other in the region between the package outer edge 71 and the first fixing part 91 , the outer edge fixing part 95 can fix the main release sheet 50 to the packaging material 70 . Therefore, the main body adhesive portion 6 can be easily separated from the main body release sheet 50 without pressing the main body release sheet 50 toward the packaging material side by hand or the like. The outer edge fixing portion 95 may be positioned closer to the package outer edge 71 than the second fold line F2. Outside the pocket P, the body release sheet 50 can be fixed to the packaging material 70 . When the user pulls the absorbent article 1 and the packaging material 70 away from each other outside the pocket P, the main body release sheet 50 can be fixed to the packaging material 70 side via the outer edge fixing part 95, and the main body adhesive The part 6 can be peeled off from the main body peeling sheet 50 in a direction perpendicular to each other.

A distance L51 along the front-rear direction L between the outer edge fixing portion 95 and the package outer edge 71 is shorter than a distance L52 along the front-rear direction L between the outer edge 6S1 of the main body adhesive portion 6 in the outer region R10 and the package outer edge 71. you can That is, the outer edge fixing portion 95 may be positioned closer to the package outer edge 71 than the main body adhesive portion 6 . According to this configuration, the main body release sheet 50 is fixed to the packaging material 70 side in the region overlapping the outer edge 6S1 of the main body adhesive portion 6 . Therefore, when the packaging material 70 and the absorbent article 1 are pulled from the package outer edge 71 side in the direction of separating them from each other, the main body adhesive portion 6 can be smoothly peeled off from the main body release sheet 50 . Note that the first fixing portion 91 and the outer edge fixing portion 95 may be connected to each other or may be separated from each other. In the form in which the first fixing portion 91 and the outer edge fixing portion 95 are spaced apart, another fixing portion (for example, the third fixing portion 93 of the second embodiment) is provided between the first fixing portion 91 and the outer edge fixing portion 95. Alternatively, the third non-fixed portion 83 may be provided between the first fixed portion 91 and the outer edge fixed portion 95 . By providing the third non-fixed portion 83, the degree of freedom during deformation of the body release sheet 50 is increased, and the absorbent article 1 can be pulled out more smoothly.

The region between the second fold line F2 and the first fold line F1 is a region overlapping with the second non-fixed portion 82. By pulling the packaging material 70 and the absorbent article 1 away from each other, the main body release sheet 50 can be absorbed. Follows the sexual item 1. The main body release sheet 50 is joined to the packaging material 70 at the second fixing part 92 and the first fixing part 91, and follows the main body adhesive part 6 in the region between the second fixing part 92 and the first fixing part 91. Then, it is deformed so as to be lifted from the packaging material 70 at the first fold line F1.

When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the states shown in FIGS. 10(b) and (e) are obtained. 10(b) and (e) show the state where the absorbent article 1 is separated from the packaging material 70 and the body release sheet 50 up to the area beyond the first fold line F1. The body release sheet 50 is further deformed so as to follow the body adhesive part 6 and rise from the packaging material 70 at the first fold line F1. When the user further pulls the packaging material 70 and the absorbent article 1 away from each other, the states shown in FIGS. 10(c) and 10(f) are obtained. 10(c) and (f) show a state in which the absorbent article 1 is separated from the packaging material 70 and the body release sheet 50 up to the region overlapping the first fixing portion 91. FIG. The main body release sheet 50 is fixed to the inner edge 91V of the first fixing portion 91 and floats up with the inner edge 91V of the first fixing portion 91 as a base point. In the area closer to the package inner edge 72 than the inner edge 91V of the first fixing portion 91, the main body adhesive portion 6 is gradually peeled off from the main body release sheet 50 toward the package inner edge 72 side. Peeling can be performed in directions perpendicular to each other, and shearing stress due to the main body adhesive portion 6 is less likely to occur, enabling smooth peeling.

That is, in the third embodiment, when the absorbent article 1 is peeled off from the outer region R10, the absorbent article 1 is pulled away from the outer region R10, that is, toward the inner region R20. After the absorbent article 1 is separated from the outer region R10, the absorbent article 1 is pulled up with respect to the inner region R20 (pulled in a direction away from the first fold line F1). When the main body adhesive portion 6 is peeled off from the main body release sheet 50 in the inner region R20, the main body adhesive portion 6 and the main body release sheet 50 are gradually peeled from the first fold line F1 side, and the surfaces of the main body adhesive portion 6 and the main body release sheet 50 are perpendicular to each other. peeled off. Therefore, the main body adhesive portion 6 and the main body release sheet 50 can be separated from each other while suppressing the generation of shear stress. At this time, since the first non-fixed portion 81 is provided so as to overlap the first fold line F1, the body release sheet 50 is lifted and deformed with respect to the packaging material 70 in the vicinity of the first fold line F1. When the main body adhesive part 6 and the main body release sheet 50 are pulled, the generation of shearing stress can be further suppressed and the body release sheet 50 can be smoothly peeled off.

In the first folded state, when the absorbent article 1 is pulled in the width direction (width direction) and pulled in the front-back direction L, the absorbent article 1 is pulled out from the packaging material 70 while being tilted. At this time, the area between the first side joint portion 61 and the first fixing portion 91 in the width direction W is an area where the body release sheet 50 is not stopped with respect to the packaging material 70 and can move freely. On the other hand, the region between the outer edge 61S of the first side joint portion 61 and the outer edge 91S of the first fixing portion 91 in the front-rear direction L extends along the direction in which the absorbent article 1 is pulled out and can be freely moved. It is difficult to become an area. In addition, the outer edge 61S of the first side joint portion 61 and the outer edge 91S of the first fixing portion 91 are base points for deformation of the main body release sheet 50 with respect to the packaging material 70, respectively. If the base points of deformation are too far apart, a load is applied to the first side joint portion 61, and the joint state of the first side joint portion 61 may not be maintained. However, since the length of the region between the first side joint portion 61 and the first fixed portion 91 in the width direction W (the region where the region can be freely moved) is long, the load applied to the outer edge 61S of the first side joint portion 61 can be suppressed, and the bonding state of the first side bonding portion 61 can be maintained.

In addition, in the second and third embodiments, the first side joint portion 61 may have the high joint portion 611 and the low joint portion 612 as in the first embodiment. In the form having the high joint portion 611 and the low joint portion 612, the opening edge of the pocket P may be the outer edge 61S of the first side joint portion 61 or the outer edge of the high joint portion 611. , the outer edge of the low bonding portion 612, or the outer edge of the portion where the low bonding portion 612 is partially peeled off. Further, in the second and third embodiments, the first side joint portion 61 may have substantially constant peel strength without the high joint portion 611 and the low joint portion 612 .

The width fold line of the package 104 has a first fold line F1, a second fold line F2, and a third fold line located between the first fold line and the package inner edge 72. As shown in FIG. The first fold line F1, the second fold line F2 and the third fold line F3 are fold lines formed by folding the packaging material 70, the body release sheet 50 and the absorbent article 1. As shown in FIG. The wing release sheet 52 is folded via the first crease F1. One region of the wing release sheet 52 bounded by the first fold line F1 covers the wing adhesive portion 7, and the other region bounded by the first fold line F1 covers the flap adhesive portion 8.

The first region of the fourth embodiment is configured by the outer region R10. The fixing portion 90 has at least a first fixing portion 91 and a second fixing portion 92 . The first fixing portion 91 is separated from the first fold line F1 and positioned closer to the package outer edge 71 than the first fold line F1. The second fixing portion 92 is separated from the first fold line F1 and positioned closer to the package inner edge 72 than the first fold line F1. The second fixing portion 92 is arranged between the third fold line F3 and the inner edge 72 of the package. The fixed portion of the wrapper 104 may not be located between the second fold line F2 and the third fold line F3, nor may it be located between the third fold line F3 and the inner edge 72 of the package. As shown in the take-out mode of the absorbent article 1 described later, when the inner region R20 on the package inner edge 72 side of the first fold line F1 is unfolded from the first fold line F1, the entire inner region R20 is covered with the wing release sheet. 52, it is pressed in a direction away from the outer region R10, and the main body release sheet of the inner region R20 is less likely to rise from the packaging material 70. Therefore, it is not necessary to provide the fixing portion 90 between the second fold line F2 and the third fold line F3. Moreover, the package 104 may have an outer edge fixing portion 95 .

By providing the fixed portion 90, the non-fixed portion 80, and the main body adhesive portion 6 at appropriate positions, the package 104 can be folded into a pocket in the packaging material 70 when the user takes out the absorbent article 1 in the first folded state. It is configured such that the absorbent article 1 can be taken out while forming P (while maintaining the joining by the first side joining portion 61).

The wrapping material 70 and the absorbent article 1 are pulled away from each other. The wrapping material 70 and the absorbent article 1 are pulled away from each other so that the front end of the absorbent article 1 and the package outer edge 71 are separated. When the user continues to separate the absorbent article 1 and the packaging material 70 and applies force to the outer edge 61S of the first side joint 61, the low joint provided at the outer edge 61S of the first side joint 61 is broken. Part 612 separates. Figures 12(a) and (d) show the state where the low joint 612 is separated. The high joint portion 611 is arranged closer to the first fold line F1 than the low joint portion 612 , and the separation of the packaging materials stops at the outer edge 611S of the high joint portion 611 .

When the user further pulls the absorbent article 1 of the inner region R20 and the outer region R10 away from each other, the inner region R20 rotates around the third fold line F3. At this time, the fixing portion 90 is not arranged in the region overlapping the first fold line F1, and the main body release sheet 50 is lifted from the packaging material 70. As shown in FIG. Therefore, the inner region R20 moves out of the pocket P while maintaining the bonded state of the high bonded portion 611 of the packaging material 70 . When the user further pulls the absorbent article 1 in the inner region R20 and the outer region R10 in a direction away from each other, the inner region R20 is further rotated around the third fold F3 and wrapped around the first fold F1.

The entire front-rear direction of the absorbent article 1 can be attached to the worn article, and the body release sheet 50 in each area can be deformed following the absorbent article 1 when the absorbent article 1 is taken out. Moreover, although the body release sheet 50 is continuous in the front-rear direction L in the above-described embodiment, it may be divided into a plurality of pieces in the front-rear direction. In the form in which the main body release sheet 50 is divided, the main body release sheet 50 may not be placed in the region overlapping the first fold line F1, and the first fold line F1 may be sandwiched between the main body release sheet 50 and the main body release sheet 50. FIG.

In the first embodiment to the fourth embodiment, the package body may be such that the packaging materials 70 are joined to each other by an adhesive at the unsealing joint in the opening region including the package outer edge 71, and the package outer edge 71 is sealed. . In the form having the opening joint portion, the tape member 75 may be provided, or the tape member 75 may not be provided. The unsealing joint may be arranged between the pair of first side joints 61 in the multi-layered portion 77 in the width direction W, and between the first side joint 61 and the second side joint 62 in the thickness direction T. may be placed in That is, the first side joint portion 61 and the unsealing joint portion may overlap in the thickness direction T. As shown in FIG. In the form in which the first side joint portion 61 and the unsealable joint portion overlap, the length of the unsealable joint portion in the front-rear direction L may be shorter than the length of the first side joint portion 61 in the front-rear direction. According to this aspect, it is possible to prevent the first side joint portion 61 from coming off unintentionally, and to prevent the pocket from being damaged when the bag is opened.

In the first to fourth embodiments, the joint strength per unit area of the high joint portion 611 may be higher than the joint strength per unit area of the unsealing joint portion. According to this aspect, the bonded state of the high bonded portion 611 can be maintained while the unsealed bonded portion is peeled off. A sample for measuring bonding strength per unit area can be obtained, for example, by the following method. A sample of the unsealing joint portion is cut across the center of the package in the width direction and has a length of 15 mm in the width direction. Also, as a sample of the strong joint portion, the strong joint portion is cut into a predetermined size (for example, 15 mm) in the first folded state. Bonding strength can be evaluated by peel strength measured by Instron.

In the first to fourth embodiments, at least one of the packaging material 70 and the main body release sheet 50 may be provided with a pocket display part PD that reminds of a pocket P. As an example, the pocket display part PD is shown in the first embodiment. The pocket display part PD may be anything as long as it informs the user that the package 101 has a pocket P, and may be information such as characters, or may be a pattern such as the shape of the pocket P. . By providing the pocket display part PD, it becomes easier for the user to recognize the function of the pocket P. A front-rear edge (packaging outer edge) 71 of the packaging material located outside the packaging body in the packaged state may overlap the pocket display portion. According to this aspect, the pocket display part PD is divided by the package outer edge 71, and the pocket display part PD becomes more conspicuous. Therefore, it becomes easier for the user to recognize the pocket display part PD and grasp the existence of the pocket P. Moreover, at least part of the pocket display part PD may be arranged on the outer surface of the package in the packaged state. According to this aspect, since the pocket display portion is arranged on the outer surface in the wrapped state, the user can easily recognize the pocket display portion in the wrapped state and grasp the presence of the pocket.

In addition, the portion of the packaging material 70 that constitutes the pocket P is provided with a pocket display portion PD that reminds of the pocket P, and the non-pocket portion is provided with a pattern Dn different from the pocket display portion PD. you can The non-pocket N is a portion of the packaging material 70 where the pocket P is not provided, and is configured by a portion closer to the package outer edge 71 than the pocket P is. The pocket display part PD is a pattern of letters "POCKET" which means a bag, and the pattern Dn is a polka dot pattern. In this way, it is preferable to use different patterns for the pocket display part PD and the pattern Dn. This makes it easier for the user to recognize the existence of the pocket P. Moreover, it is more preferable to make the pocket display part PD into a pattern for reminding of the pocket P. FIG. This makes it easier for the user to recognize the functions of the pocket P. Note that the pocket display part PD is not necessarily limited to the letters "POCKET". For example, the pocket display portion and the pattern Dn may have different colors and different patterns. The pocket display portion and the pattern Dn may be printed on the packaging material 70 by inkjet or the like, or may be affixed to a separate member having the pocket display portion and the pattern Dn. Further, as shown in FIG. 3, at least part of the pocket display part PD and at least part of the design Dn may be visible before the package is opened, that is, in the packaged state. Since different designs are arranged in the packaged state, the user can recognize the pocket display part PD when the package is taken out of the package.

Furthermore, as shown in FIG. 4, it is more preferable to provide a marking portion M at the end of the pocket P on the opening edge side. The marking portion M is a portion indicating the opening of the pocket P, and includes at least a pocket display portion provided in the pocket P and a pattern Dn provided in the non-pocket N, and at least a shape, pattern, color, or tactile sensation. One is different. For example, when the pattern of the pattern provided in the stamp part M is different from the pocket display part and the pattern Dn, when the thickness of the stamp part M is thicker than the pocket display part and the pattern Dn, or when the pattern etc. is not provided and pressed A pattern Dn having a predetermined pattern (such as a pattern) on a smooth surface can be exemplified for the marking portion M having unevenness formed by processing or the like. By providing the marking portion M, it becomes easier for the user to recognize the presence of the pocket P and the position of the opening of the pocket P.

In the first to fourth embodiments, it is preferable that the amount of moisture inside the pocket P is equal to or less than the amount of moisture contained in the absorbent article 1 . It is possible to reduce the possibility that the opening of the pocket P will be closed by moisture. In particular, when the packaging material 70 is formed of a film such as a plastic film or a nylon film as in the above-described embodiment, there is a risk that the packaging materials 70 facing each other at the opening of the pocket P will stick to each other due to moisture. There is Therefore, by setting the amount of water inside the pocket P to be equal to or less than the amount of water contained in the absorbent article 1, the amount of water inside the pocket P is more than the amount of water contained in the absorbent article 1. This reduces the possibility that the packaging materials 70 facing each other at the opening of the pocket P stick to each other due to moisture, and makes it easier for the user to widen the opening.

The moisture content of the inside of the pocket P and the absorbent article 1 can be compared by measuring each moisture content by the following method and using the obtained results. The amount of moisture inside the pocket P is determined by first opening the packages 101 to 104 in the packaged state, removing the absorbent article 1, cutting the pocket P from the packaging material 70, and wiping off the moisture on the outer surface of the pocket P. Measure the weight of the pocket P when it is opened. Subsequently, the side joints 60 provided at both ends of the pocket P in the horizontal direction are peeled off, and the inner surface of the pocket P is exposed at a predetermined temperature (for example, 25° C.) for a predetermined time (for example, 24° C.). time) to dry. Then, by measuring the weight of the pocket P after drying and calculating the difference from the weight of the pocket P when it is opened, the moisture content inside the pocket P can be obtained. The moisture content of the absorbent article 1 is measured by first opening the package 101 in the wrapped state and measuring the weight of the absorbent article 1 when the packaging material 70 is removed. Subsequently, the absorbent article 1 is dried at a predetermined temperature (eg, 25° C.) for a predetermined time (eg, 24 hours). By measuring the weight of the absorbent article 1 after drying and calculating the difference from the weight of the absorbent article 1 when it is unsealed, the amount of moisture contained in the absorbent article 1 can be obtained.

It is preferable that no wiping wipes be stored inside the pocket P of the package. Wipes are sanitary wipes used by the user to wipe off menses and other bodily wastes. Wiping wipes can be liquid-containing wipes in a wet state, and also include dry wipes in a dry state. Since the wiping wipe is not stored inside the pocket P, the package 101 is less likely to be bulky and can be made more compact. Moreover, since the wiping wipe is not stored in the pocket P, the user can easily store the absorbent article 1 in the pocket P after use.
