=== Outline of the embodiment ===
The description of the present specification and the accompanying drawings will clarify at least the following matters.
The package of the absorbent article according to one embodiment includes an absorbent article having an absorbent core and a skin surface sheet arranged on the skin surface side of the absorbent core in the front-rear direction and the width direction orthogonal to each other, and the absorbent article. With the packaging sheet for individually wrapping the articles and the absorbent article and the packaging sheet stacked on top of each other, the skin surfaces of the absorbent articles face each other with the pair of front and rear creases along the front-rear direction as base points. A package of an absorbent article to be folded, wherein the absorbent article has a joint portion for joining to the worn article on the non-skin surface of the absorbent article and a bending base point serving as a bending base point of the absorbing core. The bent base point portion extends in the front-rear direction and is arranged on both sides in the width direction with the center in the width direction of the absorbent article, respectively, and the pair of front-rear folds. Is arranged in a region that overlaps with the absorption core and does not overlap with the joint in the unfolded state in which the pair of front and rear folds are not folded from the base point, and the bent base point is in the unfolded state. It is arranged in a region overlapping with at least one of the front and rear folds of the pair of front and rear folds.

According to this aspect, a crease is formed in the absorption core by the pair of front and rear folds and the bending base point. The absorption core in the region outside the width direction of the front-rear crease tends to rise toward the skin surface side with respect to the front-rear crease. When the absorbent article receives an inward force in the width direction while worn, the pair of front-rear creases move inward in the width direction so that the area between the pair of front-rear folds becomes convex toward the skin surface. Easy to deform. Therefore, the fit to the excretion opening can be improved when worn. Further, the pair of front and rear creases are arranged in a region that does not overlap with the joint portion. It is possible to prevent the joints from unintentionally sticking to each other when the absorbent article is attached, and to suppress defects during the attachment.

According to a preferred embodiment, the bent base point portion may be provided in a region overlapping both of the pair of front and rear folds in the unfolded state.

According to this aspect, the creases due to both front and rear folds can be stably formed, and the fit of the region between the front and rear folds to the excretion port can be improved. In addition, by strengthening the folding habit, the front and rear folds when the package is folded become more stable, and the package can be easily folded compactly.

According to a preferred embodiment, the bent base point portion may be arranged on the skin surface side of the center in the thickness direction of the package in the unfolded state.

According to this aspect, since the folding base point portion is arranged on the skin surface side of the center in the thickness direction of the package, the absorbent article is folded toward the skin surface side with the folding base point portion and the front-rear crease as the base points. It becomes easy to get rid of. Folding habits due to the front and back folds can be stably formed, and the fit of the area between the front and back folds to the excretion port can be improved.

According to a preferred embodiment, the joint has a body joint arranged in a region overlapping the absorption core, and the body joint may be arranged only in the region between the pair of front and rear creases.

According to this aspect, the region where the main body joint is arranged between the pair of front and rear creases is likely to be pulled up by the wearer side following the worn article at the time of wearing. Therefore, the fit of the absorption core to the excretion port can be further improved. On the other hand, in the region outside the width direction of the front-rear crease, the main body joint is not arranged, and it is easy to stand up with respect to the worn article. Therefore, the outer portion of the absorption core tends to rise toward the wearer side, and lateral leakage can be easily suppressed.

According to a preferred embodiment, the absorbent article comprises a central region facing the wearer's excretion port, a posterior region located posterior to the central region, and an anterior region located anterior to the central region. The bent base point portion may have at least a core squeezed portion in which the absorbing core is compressed in the thickness direction, and the core squeezed portion may be arranged at least in the central region.

According to this aspect, when a force is applied inward in the width direction during wearing, the core squeezed portion is easily deformed from the base point in the central region. In the central region, the inner region in the width direction is more likely to be deformed more convexly than the front and rear folds, and the fit to the excretion opening in the region between the front and rear folds can be improved.

According to a preferred embodiment, the bent base point may be arranged along the anteroposterior direction and overlap both of the pair of anterior-posterior folds.

According to this aspect, since the folding base point portion and the pair of front-rear folds are both along the front-rear direction, when folding from the unfolded state with the front-rear crease as the base point, the folding base point portion tends to be the fold base point, and the front-rear fold is formed. It becomes easy to fold to the base point. Further, the folding habit due to the bending base point portion and the pair of front and rear creases is likely to be formed more strongly.

According to a preferred embodiment, the skin surface sheet has a convex portion extending in the front-rear direction and a concave portion recessed in the thickness direction from the convex portion and extending in the front-rear direction, and the bent portion. The base point portion may have a sheet uneven portion including at least one of the convex portion and the concave portion.

According to this aspect, the uneven portion of the sheet extends in the front-rear direction, and a pair of front-rear creases extending in the front-rear direction can be stably formed. It is possible to improve the rise on the skin surface side in both outer regions in the width direction as compared with the pair of front and rear folds, and to improve the fit of the region between the front and rear folds to the excretion port. In addition, the front and rear folds of the package in the folded state are more stable, and the package can be easily folded compactly.

According to a preferred embodiment, the absorption core has a high basis weight portion in which the basis weight of the absorbing material is higher than that of the surroundings, and the high basis weight portion is in the width direction of the pair of front and rear folds. It is arranged only on the inside, and the high basis weight portion may be arranged in a region that does not overlap with the portion folded from the pair of front and rear folds in the absorption core as a base point.

According to this aspect, in a state of being folded with a pair of front and rear folds as a base point, the absorption core folded with the front and rear folds as a base point suppresses the high basis weight portion from being crushed, and the shape of the high basis weight portion is changed. It can be maintained, and the fit to the excretion port and the absorption performance of body fluid can be ensured.

According to a preferred embodiment, the absorbent article and the packaging sheet are folded from a pair of front-rear creases along the front-rear direction and a pair of width folds along the width direction as a base point. The bent base point portion may be arranged in a region overlapping at least one of the pair of width folds in the unfolded state.

According to this aspect, since the folding base points are overlapped with each other in the pair of width folds, the width folds are easily deformed from the base points, and the creases due to the width folds are easily formed. The folding habit makes it easier to fold the package compactly.

According to a preferred embodiment, there is a core recess that is recessed on the non-skin surface side in the region sandwiched between the pair of front and rear folds, and the joint portion may be arranged in a region that overlaps the core recess in a plan view. ..

The region outside the width direction of the pair of front-rear creases overlaps the region sandwiched between the pair of front-rear folds in a state where the pair of front-rear folds are folded by the base point. Since the core recess is provided in the area sandwiched between the pair of front and rear folds, it is possible to prevent the area between the pair of front and rear folds from becoming too thick when the pair of front and rear folds are folded by the base point. However, it becomes easier to fold the package compactly. Further, since the joint portion is arranged in a region overlapping the core recess in a plan view, it is possible to prevent the region in which the core recess is arranged from becoming too rigid and maintain a fit to the excretion port when worn. ..

According to a preferred embodiment, the absorbent article comprises a central region facing the wearer's excretion port, a posterior region located posterior to the central region, and an anterior region located anterior to the central region. The bent base point portion has at least a core pressing portion in which the absorbing core is compressed in the thickness direction, and the core pressing portion may be arranged so as to surround the core recess in the central region. ..

Since the core pressing portion is arranged so as to surround the core recess in the central region, the rigidity of the region where the core recess is arranged can be increased by the core pressing portion. Therefore, it is possible to prevent the rigidity of the region where the core recess is arranged from becoming too low, and to maintain the fit to the excretion port when worn.

According to a preferred embodiment, the absorbent article and the packaging sheet are folded at a base point of a pair of front-rear folds along the front-rear direction and at a base point of a pair of width folds along the width direction. The absorption core has a high basis weight portion in which the basis weight of the absorbing material is higher than that of the surroundings, and the high basis weight portion is larger than the pair of width folds in a state where the absorption core is not folded by the pair of width folds. On the rear side, it may be arranged in a region that does not overlap with the pair of width folds.

The high basis weight portion is thicker than the surroundings, and in a form in which the high basis weight portion and the width fold overlap, it may be difficult to fold the high basis weight portion when folding the width crease as a base point. However, since the high basis weight portion does not overlap with the pair of width folds, it becomes easy to fold the package compactly based on the width folds. Further, when folding the package with the pair of width folds as the base points, generally, the area behind the pair of width folds is folded back with respect to the area sandwiched by the pair of width folds. At this time, the rigidity of the region behind the pair of width folds can be increased by the high basis weight portion, and the package can be stably folded.

The bent base points 80 are separated from the article width center line 1WC in the width direction W, and may be arranged in pairs with the article width center line 1WC in between. The pair of bent base points 80 may be line-symmetrical or asymmetrical with respect to the article width center line 1WC.

(2) Folding Mode of Package 100 of Absorbent Article Next, a folding mode of the package 100 of the absorbent article will be described with reference to FIG. The package 100 of the absorbent article is folded through a plurality of folds in a state before use. In the package 100 of the absorbent article, the absorbent article 1 and the packaging sheet 70 are overlapped with each other so that the skin surfaces of the absorbent article 1 face each other with the pair of front-rear creases FL along the front-rear direction L as the base points. Folds in. The pair of front-rear creases FL has a first front-rear crease FL1 and a second front-rear fold FL2. The first front-rear crease FL1 and the second front-rear fold FL2 are separated from each other in the width direction W.

1 and 2 show a package in an expanded state in which the package 100 of the absorbent article is expanded. In the unfolded state, the absorbent article 1 and the packaging sheet 70 are stacked, and all the folds (in the present embodiment, a pair of front-rear fold FLs, a pair of width folds FW, and a front-rear fold FL only are provided in the front-rear direction. It is in a state where it is not folded from the crease). The unfolded state is a state in which the package 100 of the folded absorbent article is unfolded or a state before the package 100 of the absorbent article is folded. Further, the stretched state is a state in which the stretched state is stretched to a state in which wrinkles are not formed by the elastic member or the like. 1, FIG. 2 and FIG. 3 show a package in an unfolded and stretched state. FIG. 6 shows a package in an unfolded state and a non-stretched state. In the state shown in FIG. 6, the package is deformed due to the folding habit of the front-rear crease FL.

In the unfolded state, the non-skin surface sheet 20 of the absorbent article 1 and the inner surface 70X of the packaging sheet 70 face each other. The absorbent article 1 and the packaging sheet 70 are folded together in a stacked state. Specifically, in the unfolded state in which the absorbent article 1 and the packaging sheet 70 are overlapped and not folded with respect to the first front-rear fold FL1 and the second front-rear fold FL2 as the base points, the absorbent article 1 and one outer edge of the absorbent article 1 are overlapped with each other. One outer edge of the packaging sheet 70 is folded with the first front-rear crease FL1 as a base point. The first front-rear fold FL1 is a front-rear fold for folding along the front-rear direction L so that the skin-side T1s of the absorbent articles face each other. FIG. 5A shows a first folded state in which the first front and rear folds FL1 are folded as a base point.

In the first folded state of the absorbent article 1 and the packaging sheet 70, the other outer edge of the absorbent article 1 and the other outer edge of the packaging sheet 70 are folded with the second front-rear fold FL2 as a base point. The second front-rear fold FL2 is a front-rear fold for folding so that the skin-side T1s of the absorbent articles face each other along the front-rear direction L. FIG. 5B shows a second folded state in which the second front and rear folds FL2 are folded as a base point. In the second folded state, the absorbent article 1 is wrapped by the wrapping sheet 70 and contained in the wrapping sheet 70.

The absorbent article 1 and the packaging sheet 70 may be folded with a pair of width folds FW as a base point in the second folded state. The pair of width folds FW has a first width fold FW1 and a second width fold FW2. The first width fold FW1 and the second width fold FW2 are separated from each other in the front-rear direction L. The first width fold FW1 and the second width fold FW2 extend along the width direction W. FIG. 5C shows a width-folded state in which the first width fold FW1 and the second width fold FW2 are folded as base points. By being folded in this way, the absorbent article 1 is miniaturized by shortening the length in the width direction W and the length in the front-rear direction L. The front edge of the packaging sheet 70 is joined to the outer surface 70Y of the packaging sheet 70 by the engaging tape 75 in a state of being folded by the first width fold FW1 and the second width fold FW2. As a result, the individually packaged state in which the absorbent articles 1 are individually packaged by the packaging sheet 70 can be maintained, and compact portability can be realized. In the modified example, the package 100 of the absorbent article may not be folded with the first width fold FW1 and the second width fold FW2 as the base points.

(3) Usage of the packaging of the absorbent article The packaging of the absorbent article 100 according to the present embodiment is configured to improve the fit when worn while suppressing defects during mounting. There is. In addition, the package 100 of the absorbent article according to the present embodiment is configured to be easy to fold at the time of the above-mentioned folding and to stably form the front-rear crease FL. Next, the usage mode of the package of the absorbent article, that is, the mounting mode and the wearing mode will be described.

The package 100 of the absorbent article is folded before use. When the user unfolds the package 100 at the time of wearing and wearing, the absorbent article 1 is formed with a fold habit due to the first front-rear crease FL1 and the second front-rear crease FL2. FIG. 6 shows a developed state in the cross section shown in FIG. FIG. 7 shows a wearing state in which the absorbent article 1 in the cross section shown in FIG. 3 is attached to the worn article S. In the unfolded state shown in FIGS. 6 and 7, the package once folded is unfolded with the first front-rear crease FL1 and the second front-rear fold FL2 as the base points, and the first front-rear fold FL1 and the second front-rear fold FL2 are the base points. It is in a state where it is not folded. In the unfolded state, the region outside the width direction W of the first front-rear crease FL1 is more likely to rise to the skin surface side T1 than the first front-rear crease FL1 due to the fold habit, and is outside the width direction W of the second front-rear fold FL2. The region of is raised on the skin surface side T1 from the second front and rear crease FL2 due to the crease.

In the unfolded state, the first front-rear crease FL1 and the second front-rear fold FL2 are provided in a region overlapping the absorption core 30. Therefore, the absorption core 30 of the absorbent article 1 is formed with a fold habit due to the first front-rear crease FL1 and the second front-rear crease FL2. At least a part of the first front-rear crease FL1 and at least a part of the second front-rear crease FL2 may be provided in a region overlapping the absorption core 30.

Further, the bending base point portion 80 is arranged in a region overlapping with at least one of the first front-rear fold FL1 and the second front-rear fold FL2. At least a part of the folding base point portion 80 may be provided in a region overlapping the first front-rear crease FL1 and the second front-rear crease FL2. Due to the presence of the bent base point 80, the folding habit of the absorbed core 30 in the unfolded state is formed more strongly. As shown in FIG. 6, the outer portion of the absorption core 30 tends to rise with the first front-rear crease FL1 and the second front-rear crease FL2 as base points. Therefore, the region outside the width direction W from the first front-rear crease FL1 and the region outside the width direction W from the second front-rear crease FL2 rise toward the skin surface side due to the crease. The absorption core 30 is arranged so as to cover the side of the excretion port, and lateral leakage can be suppressed.

In the wearing state shown in FIG. 7, the absorbent article 1 is sandwiched by legs or the like and is susceptible to a force from the outside to the inside in the width direction W. FIG. 7A is a state before receiving a force from the outside to the inside in the width direction W, and FIG. 7B is a state after receiving a force from the outside to the inside in the width direction W. .. When the absorbent article 1 receives a force toward the inside of the width direction W, the first front-rear crease FL1 and the second front-rear fold FL2 move inward of the width direction W, and the area between the pair of front-rear fold FLs is on the skin surface side. It is easy to deform so that it becomes convex. Therefore, the fit of the absorption core 30 to the excretion port when worn can be improved.

Further, the first front-rear crease FL1 and the second front-rear fold FL2 are arranged in a region that does not overlap with the joint portion 60 in the unfolded state. In the unfolded state, the main body joint 61 is arranged in the region between the first front-rear crease FL1 and the second front-rear fold FL2, and the wing joint 63 and the flap joint 64 are W in the width direction with respect to the first front-rear fold FL1. It is arranged in the outer region of the above and in the outer region in the width direction W from the second front-rear crease FL2. For example, in the form in which the joints straddle the front-rear crease FL, there is a possibility that the joints straddling the front-rear crease FL may stick to each other due to the crease. In addition, the periphery of the front-rear crease FL is easily twisted due to creases, and in a form in which the front-rear crease FL and the joint overlap, a problem occurs in which the joint that overlaps the front-rear fold FL sticks to an unintended part due to the crease. There is a risk of However, since the pair of front-rear creases FL are arranged in a region that does not overlap with the joint portion 60, it is possible to prevent the joint portion 60 from unintentionally sticking to each other and to suppress a defect during mounting.

Since the pair of front-rear crease FL and the folding base point portion 80 are provided, the front-rear crease FL is easily deformed from the base point, and the fold habit due to the front-rear crease FL is easily formed. Therefore, when the package is folded at the time of packaging or when the package is folded at the time of disposal, the folding habit makes it easy to fold the package compactly.

The main body joint 61 may be arranged only in the region between the pair of front and rear creases FL. That is, the main body joint 61 does not have to be provided in the region W in the width direction from the first front-rear crease FL1 and may not be provided in the region outside the width direction W from the second front-rear fold FL2. The area where the main body joint 61 is arranged between the pair of front and rear creases FL is likely to be pulled up by the wearer side following the worn article at the time of wearing. Therefore, the fit of the absorption core 30 to the excretion port can be further improved. On the other hand, in the region outside the width direction W of the first front-rear fold FL1 and the region outside the width direction W of the second front-rear crease FL2, the main body joint 61 is not arranged and it is easy to stand up with respect to the worn article. .. Therefore, the outer portion of the absorption core 30 is likely to stand up toward the wearer side, and lateral leakage is easily suppressed. In addition, depending on the presence or absence of the main body joint portion 61, there is a difference in rigidity between the region between the pair of front-rear creases FL and the region outside the width direction W of the pair of front-rear creases FL. Folding stability and side leakage prevention effect can be further exhibited.

Further, in the form having the main body release sheet (not shown) covering the main body joint portion 61, the outer edge of the main body release sheet is inside the first front-rear crease FL1 and the second front-rear fold FL2 in the width direction W. May be placed in. Depending on the presence or absence of the main body release sheet, there is a difference in rigidity between the region between the pair of front-rear crease FLs and the region outside the width direction W of the pair of front-rear crease FLs. Folding stability and side leakage prevention effect can be further exhibited.

The folding base point portion 80 may be provided in a region overlapping both front and rear crease FLs constituting the pair of front and rear crease FLs in the unfolded state. Folding habits due to both front and rear creases FL can be stably formed. It is possible to improve the rise on the skin surface side T1 on both outer sides in the width direction W with respect to the front-rear fold FL, and to improve the fit of the region between the front-rear fold FL to the excretion port. In addition, the front-rear crease FL when the package is folded becomes more stable, and the package can be easily folded compactly.

The bent base point 80 may be arranged on the skin surface side T1 of the package in the thickness direction T in the unfolded state. More preferably, the bent base point 80 may be arranged on the skin surface side T1 of the absorbent article 1 in the unfolded state with respect to the center in the thickness direction. In the state where the bent base point portion is arranged closer to the skin surface side than the center in the thickness direction, at least a part of the bent base point portion 80 is thick in the unfolded state and the extended state shown in FIG. It suffices if it is located on the skin surface side of the center of the direction T. The pair of front-rear creases FL are folds that fold the absorbent article 1 toward the skin surface side. According to this configuration, the package can be more easily folded toward the skin surface side with the bent base point portion and the front-rear crease FL as the base points.

The folding base point 80 may be provided in the central region S2. Preferably, the core pressing portion 35 may be arranged at least in the central region S2, and more preferably, the central core pressing portion 352 may be provided. The central region S2 is likely to be pinched by the legs when worn, and is susceptible to an inward force in the width direction W. When a force is applied inward in the width direction W during wearing, the central core squeezed portion 352 is easily deformed as a base point. The region inside the width direction W is more easily deformed in a convex shape than the central core pressing portion 352, and the fit of the absorption core 30 to the excretion port can be improved.

The folding base point portion 80 may be provided in the rear side region S3. The outer side of the absorption core in the posterior region can be raised to the skin surface side, covering the side of the bulge of the buttocks and suppressing lateral leakage. Preferably, the bending base point portion 80 may be provided in each of the central region S2, the front side region S1 and the rear side region S3. The absorption core can be arranged so as to cover the side of the excretion port over the entire central region S2, front side region S1 and rear side region S3, and lateral leakage can be suppressed.

The folding base point portion 80 may be arranged along the front-rear direction L and overlapping both of the pair of front-rear crease FLs. Since the folding base point 80 and the pair of front-rear crease FLs are both along the front-rear direction, the folding base point 80 tends to be the fold base point when folding from the unfolded state with the front-rear crease FL as the base point, and the front-rear fold FL is the base point. It becomes easy to fold. Further, the folding habit due to the bending base point portion 80 and the pair of front and rear creases FL is likely to be formed more strongly. In the present embodiment, the rear core pressing portion 353 is along the front-rear direction L and overlaps the first front-rear crease FL1 and the second front-rear crease FL2. The rear core pressing portions 353 are arranged at intervals in the width direction W. According to this configuration, in the rear side region S3, the region sandwiched by the rear core pressing portion 353 tends to rise to the skin surface side T1. The raised area fits in the gap between the buttocks, and leakage can be suppressed. The length of the bending base point 80 overlapping the pair of front-rear creases FL is not particularly limited, but is preferably 10 mm or more, and more preferably the front-rear direction of the rear region of the absorbent article. It may be 50% or more of the length of.

The bent base point portion 80 may have a sheet uneven portion 15. The sheet uneven portion 15 extends L in the front-rear direction, and can stably form a crease of a pair of front-rear creases FL extending in the front-rear direction. It is possible to improve the rise on the skin surface side on both outer sides of the width direction W as compared with the pair of front and rear fold FLs, and to improve the fit of the region between the front and rear folds FL to the excretion port. In addition, the front-rear fold FL in the folded state of the package is more stable, and the package can be easily folded compactly.

The bent base point portion 80 may have at least a sheet pressing portion 16 in which the skin surface sheet 10 is compressed in the thickness direction T. The sheet pressing portion 16 can also stably form the folding habit of the front-rear crease FL. It is possible to improve the rise on the skin surface side on both outer sides of the width direction W as compared with the front-rear fold FL, and to improve the fit of the region between the front-rear fold FL to the excretion port. In addition, the front-rear crease FL at the time of individual packaging becomes more stable, and the package can be easily folded compactly.

The sheet pressing portion 16 may be arranged outside the pair of front-rear creases FL in the width direction W. More preferably, the sheet pressing portion 16 may extend in the front-rear direction L outside the width direction W than the pair of front-rear crease FLs. Depending on the presence or absence of the sheet pressing portion 16, there is a difference in rigidity between the region between the pair of front-rear creases FL and the region outside the pair of front-rear creases FL in the width direction W. As it becomes easier to fold. Further, the region outside the width direction W of the pair of front-rear folds FL is easily raised by the rigidity of the sheet pressing portion 16, and the outer portion of the absorbent article is arranged so as to cover the side of the excretion port, and the excretion port is arranged. It is possible to improve the fit to and suppress lateral leakage.

The sheet pressing portion 16 may not be arranged at the center of the front-rear direction L of the central region S2, but may be arranged outside the center of the front-rear direction L of the central region S2 in the front-rear direction L. More specifically, it does not have to be arranged in the central region of the region obtained by dividing the central region S2 into three equal parts in the front-rear direction. The central region easily hits the legs when worn, and the seat pressing portion located outside the pair of front-rear creases FL in the width direction W may hit the legs, which may deteriorate the wearing feeling. However, since the sheet pressing portion 16 is not arranged at the center of the central region in the front-rear direction, it is possible to exhibit the fit to the excretion port, the stability of folding, and the effect of preventing lateral leakage while suppressing the deterioration of the wearing feeling. Further, the depth of the sheet pressing portion 16 may be shallower than that of the core pressing portion 35. According to this configuration, the rigidity of the seat pressing portion 16 tends to be lower than the rigidity of the core pressing portion 35, and deterioration of the wearing feeling when the seat pressing portion hits the leg can be suppressed.

The length of the core pressing portion 35 overlapping the pair of front-rear creases FL in the front-rear direction L is preferably longer than the length of the sheet pressing portion 16 extending in the front-rear direction L in the front-rear direction. Since the length of the core pressing portion 35 overlapping the front-rear fold FL is long in the front-rear direction, the fit to the excretion opening, the stability of folding, and the effect of preventing lateral leakage can be further exhibited.

The pair of front-rear creases FL may be provided in a region overlapping the edge joint 25. The edge joint portion 25 has higher rigidity than the portion where the skin surface sheet 10 and the non-skin surface sheet 20 are not joined. Therefore, a crease is likely to be formed by the pair of front and rear creases FL. The fit to the excretion opening, the stability of folding, and the effect of preventing side leakage can be further exhibited.

The high basis weight portion 33 of the absorption core 30 may be arranged only between the pair of front and rear creases FL. The fold habit of the pair of front and rear creases FL does not easily affect the high basis weight portion 33, the shape of the high basis weight portion 33 can be maintained, and the fit to the excretion port and the absorption performance of body fluid can be ensured. Further, depending on the presence or absence of the high basis weight portion 33, a difference in rigidity occurs between the region between the pair of front-rear crease FLs and the region outside the width direction W of the pair of front-rear crease FLs. Folding stability and side leakage prevention effect can be further exhibited.

The high basis weight portion 33 of the absorption core 30 may be arranged only between the pair of width creases FW. Folding habits due to the pair of width creases FW do not easily affect the high basis weight portion 33, the shape of the high basis weight portion 33 can be maintained, and the fit to the excretion port and the absorption performance of body fluid can be ensured. Depending on the presence or absence of the high basis weight portion 33, a difference in rigidity occurs between the region between the pair of width fold FWs and the region outside the pair of width folds FW in the front-rear direction L. Therefore, the stability of folding can be further exhibited.

The high basis weight portion 33 of the absorption core 30 may be arranged in a region that does not overlap with the portion of the absorption core 30 that is folded from the pair of front and rear creases FL as a base point. That is, in the first folded state shown in FIG. 5A, the outer edge of the absorption core 30 before folding and the outer edge of the high basis weight portion 33 are separated in the width direction W and are separated in the thickness direction. It does not overlap with T. According to this configuration, in the first folded state, it is possible to prevent the high basis weight portion 33 from being crushed by the absorption core 30 folded with the front and rear fold FL as the base point, and to maintain the shape of the high basis weight portion 33. The fit to the excretion port and the absorption performance of body fluid can be ensured.

The sheet pressing portion 16 may be provided in a region overlapping at least one of the pair of width fold FWs. In the present embodiment, a part of the sheet pressing portion 16 overlaps the second width crease FW2. Since the bending base point portion 80 overlaps the pair of width fold FWs, it is easy to deform the width fold FW as a base point, and the creases due to the width folds are easily formed. Therefore, when the package is folded at the time of packaging or when the package is folded at the time of disposal, the folding habit makes it easy to fold the package compactly.

In the modified example, the sheet pressing portion 16 overlapping the pair of width folds of the sheet pressing portion 16 is arranged only inside the outer edge 30E of the absorption core 30 in the width direction W, and is located more than the outer edge 30E of the absorption core 30. It does not have to be arranged outside the width direction W. While improving the stability of the folding base point by the sheet pressing portion 16, it is possible to suppress the diffusion of body fluid to the outside in the width direction W caused by the sheet pressing portion 16 and suppress lateral leakage.

In the packaged body of the present embodiment, the engaging tape 75 is fastened in the individually wrapped state. The bonding strength of the engaging tape 75 may be configured to be higher than the repulsive force of the package in the width-folded state. The repulsive force of the package in the width-folded state is the force that the package tries to return from the width-folded state to the second folded state. In the package 100 of the present embodiment, the absorption core 30 is folded with the front-rear crease FL and the width fold FW as base points, and the repulsive force of the package in the folded state tends to be high. Since the bonding strength of the engaging tape is higher than the repulsive force of the package in the width-folded state, the individually packaged state can be maintained.

Next, the package of the absorbent article according to the modified example will be described with reference to FIG. In the following description of the modified example, the same reference numerals will be used and the description of the same configuration as that of the above-described embodiment will be omitted. FIG. 8 is a plan view of the package of the absorbent article according to the modified example as viewed from the skin surface side. The packaging body 100X of the absorbent article according to the modified example has the same packaging sheet configuration as the embodiment, and the absorbent article 1X configuration is different from the embodiment. The absorbent core 30X of the absorbent article 1X according to the modified example has a core recess 37 recessed on the non-skin surface side in a region sandwiched between a pair of front and rear creases FL. The core recess 37 may be a portion having a lower basis weight of the absorbing material than the surroundings, or may be a portion having the same basis weight of the absorbing material as the surroundings but having a higher density than the surroundings. The core recess 37 may be arranged on the article width center line 1WC. The joint portion 60 may be arranged in a region overlapping the core recess 37. At least a part of the core recess 37 may overlap the joint portion 60. The joint portion 60 according to the modified example may have the same configuration as that of the embodiment. The region outside the width direction W of the pair of front-rear crease FL overlaps the region sandwiched between the pair of front-rear crease FL in a state where the pair of front-rear fold FL is folded by the base point. Since the core recess 37 is provided in the region sandwiched between the pair of front and rear crease FLs, the thickness of the region sandwiched between the pair of front and rear fold FLs becomes thicker while the pair of front and rear fold FLs are folded by the base point. It suppresses too much and makes it easy to fold the package 100X compactly. Further, since the joint portion 60 is arranged in a region overlapping the core recess 37 in a plan view, it is possible to prevent the region in which the core recess 37 is arranged from becoming too rigid, and to fit the excretion port when worn. Can be maintained.

The core pressing portion 35X may be arranged so as to surround the core recess 37 in the central region S2. The core recess 37 may be arranged in the central region S2. That is, the rear end edge and the front end edge of the core recess 37 are located in the central region S2. The core pressing portion 35X may surround the core recess 37 and may be annular. The annular core pressing portion 35X may be linear or a punctate aggregate. The core pressing portion 35X may also be arranged in the central region S2, and the trailing edge and the front edge of the core pressing portion 35X may be located in the central region S2. The core pressing portion 35X may be adjacent to the core recess 37 or may be separated from the core recess 37 within a range of 5 mm. Since the core pressing portion 35X is arranged so as to surround the core recess 37 in the central region S2, the rigidity of the region where the core recess 37 is arranged can be increased by the core pressing portion 35X. Therefore, it is possible to prevent the rigidity of the region where the core recess 37 is arranged from becoming too low, and to maintain the fit to the excretion port when worn.

The high basis weight portion 33X of the absorption core 30X may be arranged in a region that does not overlap with the pair of width fold FWs behind the pair of width folds FW in a state where the absorption core 30X is not folded by the pair of width folds FW. The state of not being folded by the pair of width folds FW is the unfolded state shown in FIG. The high basis weight portion 33X of the absorption core 30X according to the modified example is arranged in a region behind the pair of width fold FWs and does not overlap with the pair of width folds FW. That is, the front end edge of the high basis weight portion 33X is located on the rear side of the first width crease FW1. The high basis weight portion 33X is thicker than the periphery, and in a form in which the high basis weight portion 33X and the width crease FW overlap, it may be difficult to fold the high basis weight portion 33X when folding the width crease FW as a base point. However, since the high basis weight portion 33X does not overlap with the pair of width fold FWs, the package can be easily folded compactly with the width folds FW as a base point. Further, when folding the package 100X with the pair of width fold FWs as a base point, generally, the area behind the pair of width folds FW and the pair of the area sandwiched by the pair of width folds FW and the pair. The area in front of the width crease FW is folded back. At this time, the rigidity of the region behind the pair of width folds FW can be increased by the high basis weight portion 33X, and the package can be stably folded.
