Problems to be solved by the invention

In the absorbent article thus configured, the length in the front-rear direction in the folded state is approximately half that in the unfolded state, and the length in the width direction in the folded state is equal to or longer than the length in the width direction of the absorbent core. Therefore, the length in the front-rear direction and the width direction in the folded state is long, and it is difficult to compactly store the absorbent article during transportation.

Accordingly, the present invention provides a package of an absorbent article having a front waistline region, a back waistline region, and a crotch region, which can be compactly stored before use.

Detailed Description

(1) Brief description of the embodiments

At least the following matters will be made clear from the description of the present specification and the drawings.

An absorbent article package according to one embodiment includes an absorbent article and a package sheet for packaging the absorbent article, wherein the absorbent article has a front waistline region for covering a front waistline of a wearer, a back waistline region for covering a back waistline of the wearer, a crotch region disposed between the front waistline region and the back waistline region, and an absorbent core disposed at least in the crotch region, the front waistline region and the back waistline region being orthogonal to each other. The absorbent article is rolled up in the front-rear direction in a folded state: the absorbent core is folded with a pair of front and rear folding lines arranged along the front and rear direction and spaced apart from each other in the width direction as base points, and with a width folding line extending in the width direction in a region overlapping the absorbent core as a base point. The wrapping sheet individually wraps the absorbent article rolled up in the front-rear direction. The absorbent core is located on the inner side in the front-rear direction than the outer end edge in the front-rear direction of the absorbent article. In the folded state, a folded portion folded with the pair of front and rear folding lines as a base point overlaps with an area between the pair of front and rear folding lines. In the folded state, a length in the width direction of the front and rear folded portions at outer end edges in the front and rear direction of the absorbent article is longer than a length in the width direction of the front and rear folded portions at the width folding line. According to this aspect, since the length in the width direction of the front and rear folded portions at the outer end edges in the front and rear direction of the absorbent article is longer than the length in the width direction of the front and rear folded portions at the width folding line, it is possible to reduce the difference in thickness caused by the presence or absence of the absorbent core by utilizing the difference in area of the front and rear folded portions. By reducing the thickness difference between the winding start side and the winding end side, the entire winding can be uniformly wound up, and the winding can be more compactly wound up.

According to a preferred aspect, the absorbent article may be rolled up from the outer end edge side of the absorbent article in the folded state. According to this aspect, it is difficult to form a strong habitual fold in the absorbent core, and the absorbent core is easily arranged along the body.

According to a preferred embodiment, the absorbent article may be rolled up from the width folding line side in the folded state. According to this aspect, since the absorbent article is rolled up from the width fold line side, the habitual rolling up at the outer end edge in the front-rear direction of the absorbent article is relatively weak. The outer end edge in the front-rear direction of the absorbent article is disposed in the waistline region that covers the entire waistline of the wearer. It is possible to suppress a decrease in fit in the waistline region due to habitual rolling of the outer end edge in the front-rear direction of the absorbent article.

According to a preferred aspect, in the folded state, a front end edge and a rear end edge of the absorbent article may be shifted in the front-rear direction, and the absorbent article may be rolled up with an end edge side of the front end edge and the rear end edge of the absorbent article positioned on an inner side in the front-rear direction as an inner side. According to this aspect, the positions of the front edge and the rear edge of the absorbent article can be easily aligned in the rolled state. Therefore, the habitually rolled shape can be made to coincide at the front waistline region and the back waistline region.

According to a preferred embodiment, the front waistline region and the back waistline region of the absorbent article may be overlapped in the folded state, and the absorbent article may be rolled up with the front waistline region side as an inner side. When the front waistline region side is rolled up to the inside, the back waistline region is positioned outside in the rolled up state, and is formed with a habitual roll-up along the skin side in the rolled out state. The buttocks where leakage of excrement is likely to occur can be easily covered, and rear leakage can be suppressed.

According to a preferred aspect, the width folding line may fold the absorbent article so that the skin surface sides of the absorbent article face each other, the absorbent article may have nonwoven fabrics positioned on the non-skin surface of the absorbent article, and the nonwoven fabrics may abut each other in a state where the absorbent article is rolled up. In the rolled-up state of the absorbent article, the nonwoven fabrics positioned on the non-skin surface of the absorbent article are in contact with each other. The nonwoven fabric has a higher friction coefficient than the film, and the like, and the engagement state between the nonwoven fabrics is easily maintained. Therefore, the compactly rolled state is more easily maintained.

According to a preferred aspect, in the folded state, the absorbent article may have a roll-up start region located on a roll-up start side and a roll-up end region located on a roll-up end side, and the shrinkage force in the width direction of the roll-up end region may be higher than the shrinkage force in the width direction of the roll-up start region. According to this aspect, since the rolling completion region has a high contractive force, the rolling completion region is in close contact with the inside in the rolled state, and the rolled state is easily maintained. In addition, the winding-completed region is less likely to float in the wound state, and the compact wound state can be maintained more easily.

According to a preferred aspect, in the folded state, the absorbent article may have a roll-up start region located on a roll-up start side and a roll-up end region located on a roll-up end side, and a length of the roll-up start region in the width direction may be shorter than a length of the roll-up end region in the width direction. According to this aspect, since the length of the roll-up start region in the width direction is short, the roll-up start portion can be made small, and the entire roll-up can be made compact. Further, since the length of the winding-up end region in the width direction is long, the entire body can be held by the winding-up end region having a wide width in the wound-up state, and the wound-up state can be maintained more easily in a compact state.

(2) Structure of absorbent article package

The absorbent article package 1 according to the embodiment will be described in detail below with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, the drawings are schematic ones, and it should be noted that the ratio of each size and the like are different from the reality. Therefore, specific dimensions and the like should be determined with reference to the following description. In addition, the drawings may include portions having different dimensional relationships and ratios from each other.

Fig. 1 is a developed plan view of a package 1 of an absorbent article as viewed from the skin-facing surface side. The unfolded state is a state in which the folding is not performed by any of the front-rear folding line FL and the width folding line FW, which will be described later. The plan view shown in fig. 1 shows an extended state in which the absorbent article 10 is extended to a state in which no gathers are formed. The absorbent article package 1 (hereinafter referred to as package 1) includes an absorbent article 10 (hereinafter referred to as absorbent article) and a package sheet 100 for packaging the absorbent article 10. The absorbent article may be either an open-type absorbent article or a pants-type absorbent article. The open absorbent article is an absorbent article in which a side joining portion for joining the outer side portion of the waistline region is not formed, and is an absorbent article in which the outer side portion of the waistline region is joined by a fastening member such as a hook and loop fastener when worn. A pants-type absorbent article is an absorbent article in which the outer side portion of the waistline region is joined in advance. The absorbent article may be a disposable diaper or a pants-type sanitary napkin. The absorbent article of the present embodiment is an open-type disposable diaper.

Further, the outer side portion in the present invention means a portion occupying a certain range in the width direction W including an outer edge in the width direction W, and the outer side edge means an outer edge in the width direction W. The inner side portion in the present invention means a portion occupying a certain range in the width direction W including an inner edge in the width direction W, and the inner side edge means an inner edge in the width direction W. The front end portion and the rear end portion in the present invention are portions that occupy a certain range in the front-rear direction L including edges in the front-rear direction L, and the front end edge and the rear end edge are edges in the front-rear direction L. The outer end portion comprises a front end portion and a rear end portion, and the outer end edge comprises a front end edge and a rear end edge.

The absorbent article 10 may have a front-back direction L extending along the front and back body sides of the wearer, a width direction W orthogonal to the front-back direction L, and a thickness direction T extending along the skin-facing surface side T1 facing the wearer and the non-skin-facing surface side T2 facing the side opposite to the skin-facing surface side T1. The absorbent article 10 has a front waistline region S1, a back waistline region S2, and a crotch region S3. The front waistline region S1 is a region covering the front waistline (abdomen) of the wearer. The back waistline region S2 is a region covering the back waistline (back) of the wearer. The crotch region S3 is a region disposed between the front waistline region S1 and the back waistline region S2, and is a region covering the crotch of the wearer.

The absorbent article 10 may have fastening members that join the front waistline region S1 and the back waistline region S2 when worn. The fixing member may be constituted by a hook and loop fastener 90. The fastening tape 90 is configured to extend outward in the width direction W in the rear waistline region S2 and to be fixable to the non-skin surface of the front waistline region S1. The absorbent article 10 may have leg hole openings 35 that surround the leg holes of the wearer. The leg hole openings 35 are recessed inward in the width direction W at the outer side of the absorbent article 10. Leg hole openings 35 are disposed in crotch region S3. The crotch region S3 may be a region where the leg hole openings 35 are provided. In the absorbent article 10, a waist opening surrounding the waist of the wearer and a pair of leg hole openings surrounding the leg holes of the wearer are formed in a state where the fastening tape 90 is fastened. The waist opening portions may be formed by the front end edge of the front waistline region S1 and the rear end edge of the rear waistline region S2, and the leg hole openings may be formed by the leg hole opening portions 35.

The absorbent article 10 includes an absorbent core 31 containing an absorbent material. The absorbent core 31 is disposed at least in the crotch region S3. The absorbent core 31 comprises absorbent material such as comminuted pulp or superabsorbent polymer (SAP), or mixtures thereof. The absorbent core 31 may be covered by a core wrap, not shown. The absorbent body may be constituted by the absorbent core 31 and the core wrap. The core wrap may be made of tissue paper or SMS nonwoven fabric, and may be disposed on the skin-facing surface side T1 of the absorbent core 31 and the non-skin-facing surface side T2 of the absorbent core 31. The length of the absorbent core 31 in the front-rear direction L may be shorter than the length of the absorbent article 10 in the front-rear direction L. The absorbent core 31 is not disposed in the region extending from the front end edge 10F of the absorbent article to the rear side and the region extending from the rear end edge 10R of the absorbent article to the front side.

The absorbent article 10 has a skin side sheet 20 located closer to the skin-facing surface side T1 than the absorbent core 31. The skin side sheet 20 covers the absorbent core 31 and is disposed over the entire absorbent article 10. The skin side sheet 20 of the present embodiment includes a top sheet 21 and a pair of side sheets 22. In the absorbent article having the core wrap, the skin side sheet 20 is a sheet positioned closer to the skin-facing surface side T1 than the core wrap. The surface sheet 21 may be disposed across the center in the width direction W of the absorbent core 31. The side sheet 22 may be configured to cover both outer sides of the surface sheet 21. The front sheet 21 and the side sheet 22 may be made of, for example, nonwoven fabric or a liquid-permeable sheet such as an apertured plastic film.

The absorbent article 10 has a non-skin side sheet 25 positioned closer to the non-skin surface side T2 than the absorbent core 31. The non-skin side sheet 25 covers the absorbent core 31 and is disposed over the entire absorbent article. The non-skin side sheet 25 of the present embodiment includes a back sheet 23 and an exterior sheet 24. In the absorbent article having the core wrap, the non-skin side sheet 25 is a sheet located closer to the non-skin surface side T2 than the core wrap. The back sheet 23 is a liquid-impermeable sheet, and a laminate nonwoven fabric mainly composed of a polyethylene sheet, polypropylene, or the like, a breathable resin film, a sheet obtained by joining a breathable resin film to a nonwoven fabric such as spunbond or spunlace, or the like can be used. The outer sheet 24 is provided on the non-skin-facing surface side T2 of the back sheet 23 and is positioned on the non-skin surface of the absorbent article. The outer sheet 24 constitutes "a nonwoven fabric positioned on the non-skin surface of the absorbent article" in the present invention. The outer sheet 24 may be made of a liquid-permeable nonwoven fabric. The length of the back sheet 23 in the width direction W may be shorter than the length of the exterior sheet 24 in the width direction W, and the length of the back sheet 23 in the front-rear direction L may be shorter than the length of the exterior sheet 24 in the front-rear direction L.

The package 1 of the present embodiment individually packages the compactly rolled absorbent article 10 with the package sheet 100. Next, the folded form of the absorbent article 10 and the packaging form of the packaging sheet 100 will be described with reference to fig. 2. The packaging sheet 100 is a sheet in which the absorbent article 10 in a folded state is individually packaged. The packaging sheet 100 may be formed of a film or a nonwoven fabric. The packaging sheet 100 may be rectangular in the unfolded state, and the absorbent article 10 may be individually packaged by folding the packaging sheet 100 along the absorbent article 10 in the folded state, or may be formed in a bag shape in advance, and the absorbent article 10 in the folded state may be individually packaged by storing the absorbent article 10 in the bag. The absorbent article 10 is folded with a width folding line FW along the width direction W and a front-rear folding line FL along the front-rear direction L as base points. A pair of front and rear folding lines FL are arranged at intervals in the width direction. The width folding line FW is arranged along the width direction W in a region overlapping the absorbent core 31.

In the unfolded state of the absorbent article 10 (the state shown in fig. 2 a), the absorbent article 10 is folded with the front and rear folding lines FL as a base point. Fig. 2 (B) shows a state of being folded with the front and rear folding lines FL as base points. As shown in fig. 2 (C), the front-rear folded portion R1 folded with the pair of front-rear folding lines FL as a base point overlaps with the region R2 between the pair of front-rear folding lines FL. The front-rear folded portion R1 is a portion folded from the front-rear folding line FL as a base point, and is a portion located on the outer side in the width direction W than the front-rear folding line FL in the unfolded state shown in fig. 1. The region R2 between the pair of front-rear folding lines FL is a portion sandwiched by one front-rear folding line FL and the other front-rear folding line FL.

Next, the absorbent article 10 is folded with the width folding line FW as a base point. Fig. 2 (C) shows a folded state folded with the width folding line FW as a base point. Fig. 2 (C) shows the "folded state" in the present invention. The width folding line FW may be disposed in a region overlapping the absorbent core 31 in the crotch region S3. That is, the absorbent core 31 in the crotch region S3 is folded in the front-rear direction L with the width folding line FW as a base point. Here, the folded state is a state folded with at least one pair of front and rear folding lines FL and at least one width folding line FW as base points. The folding order of the width folding line FW and the front-rear folding line FL is not limited, but the front-rear folding line FL may be preferably preceded by the width folding line FW, and the width folding line FW may be a folding line for folding the absorbent article 10 in a state where the front-rear folding line FL is folded as a base point. The absorbent article 10 is folded in half with the width folding line FW as a base point, and the front waistline region S1 and the back waistline region S2 overlap.

Next, the absorbent article 10 in the folded state is rolled up along the front-rear direction L. The absorbent article 10 in the folded state has a 1 st end edge 11 on the outer edge (front end edge and rear end edge) side of the absorbent article and a 2 nd end edge 12 provided with a width folding line FW. The 1 st end edge 11 and the 2 nd end edge 12 are end edges in the front-rear direction L of the absorbent article 10 in the folded state, and extend along the width direction W. The absorbent article 10 of the present embodiment is rolled up from the 1 st end edge 11 side with the 1 st end edge 11 side as the inside. Fig. 2 (D) shows a rolled state of the absorbent article. Next, the absorbent article 10 is individually stored in the package sheet 100. Fig. 2 (E) shows a state where the absorbent article 10 is individually wrapped with the wrapping sheet 100.

According to such a configuration, in the folded state in which the absorbent article 10 is folded with the pair of front-rear folding lines FL and the width folding line FW as base points, the absorbent article 10 is rolled up in the front-rear direction L, and therefore the absorbent article 10 can be rolled up compactly. Further, since the compactly rolled absorbent article 10 is individually wrapped with the wrapping sheet 100, the rolled state can be maintained, and portability can also be improved. Further, since the absorbent article 10 is rolled up along the front-rear direction L after the absorbent article 10 is folded along the width folding line FW (in a state where the length of the absorbent article 10 in the front-rear direction L is shortened), the distance between the roll-up start side and the roll-up end side can be shortened. When the distance between the roll-up start side and the roll-up end side is long, the habitual roll-up at the roll-up start portion is strong, and the difference in the shape of the habitual roll-up is large between the roll-up start side and the roll-up end side. These problems can be suppressed by shortening the distance between the winding start side and the winding end side.

In the folded state, a length W11 (see fig. 2B) in the width direction W of the front-back folded portion R1 at the 1 st end edge (outer end edge in the front-back direction of the absorbent article) 11 is longer than a length W12 (see fig. 2B) in the width direction W of the front-back folded portion R1 at the 2 nd end edge (width folding line) 12. In the folded state, the absorbent core 31 is disposed on the 2 nd end edge 12 side, and the absorbent core 31 is not disposed on the 1 st end edge 11 side. Therefore, a difference in thickness is likely to occur between the winding start side and the winding end side. However, since the length W11 in the width direction W of the front and rear folded portion R1 at the 1 st end edge 11 is longer than the length W12 in the width direction W of the front and rear folded portion R1 at the 2 nd end edge 12, the difference in thickness caused by the presence or absence of the absorbent core 31 can be reduced by the difference in area of the front and rear folded portions R1. By reducing the thickness difference between the winding start side and the winding end side, the entire winding can be uniformly wound up, and the winding can be more compactly wound up. In order to reduce the thickness difference between the roll start side and the roll end side in this manner, the number of pieces of material on the 1 st end edge 11 side may be larger than the number of pieces of material on the 2 nd end edge 12 side. The material is a constituent member constituting the absorbent article, and an absorbent core, a sheet, and an elastic member can be exemplified.

The front and rear folding lines FL may be provided in a region not overlapping the absorbent core 31. According to this configuration, since the absorbent core 31 having relatively high rigidity is not folded with the front and rear folding lines FL as a base point, the absorbent core 31 can be easily folded, and can be stably folded. Further, the front-rear folding line FL may be located further outward in the width direction W than the absorbent core 31. When the absorbent core 31 is disposed in the region R2 between the front and rear folding lines FL and the absorbent core 31 is also disposed in the front and rear folded portion R1, the absorbent cores 31 are stacked on each other and the thickness thereof becomes large, and when the absorbent core 31 is folded with the width folding line FW as a base point, more than 4 layers are stacked, and it may be difficult to roll up the absorbent article 10 compactly. However, by positioning the front-rear folding line FL at a position outside the absorbent core 31 in the width direction W without disposing the absorbent core 31 in the front-rear folded portion R1, the thickness of the folded absorbent article 10 can be suppressed, and the absorbent article can be rolled up compactly.

The front-rear folding line FL may be a folding line that is folded so that the skin surface sides of the absorbent article 10 face each other. The region outside the front-rear folding line FL in the width direction W stands up toward the wearer due to habitual bending during use. Therefore, the side portions in the width direction W of the absorbent article 10 are deformed so as to rise toward the wearer by being bent habitually. The side of the crotch of the wearer can be covered by the habitual bending of the front and rear folding lines FL, and side leakage can be suppressed.

The absorbent article can be rolled up from the 1 st end edge (outer end edge of the absorbent article) 11 side in the folded state. In other words, the roll-up start portion may be the 1 st edge and the roll-up end portion may be the 2 nd edge 12. With such a structure, it is difficult to form a strong habitual bend in the absorbent core 31, and the absorbent core 31 is easily arranged along the body. The width folding line FW may fold the absorbent article 10 so that the skin surface sides of the absorbent article 10 face each other. With this configuration, the front waistline region S1 and the rear waistline region S2 are formed to be bent in a customary manner so as to be close to each other, and fit during wearing can be improved.

In a modification, the absorbent article 10 may be rolled up from the 2 nd end edge (width folding line) 12 side in the folded state. In other words, the roll-up start portion may be the 2 nd edge 12, and the roll-up end portion may be the 1 st edge 11. With such a structure, the habitual rolling-up at the outer end edges in the front-rear direction L of the absorbent article 10 is relatively weak. The outer end edge in the front-rear direction of the absorbent article 10 is disposed in the waistline region that covers the entire waistline of the wearer. It is possible to suppress the decrease in fit in the waistline region due to habitual rolling up of the outer end edge in the front-rear direction L of the absorbent article 10. The first end edge 1 is a region where the front end edge 10F and the rear end edge 10R of the absorbent article are stacked and not joined to each other. The first end edge 11 is a winding end portion, and therefore, due to a difference in diameter at the time of winding, positions of the front end edge 10F and the rear end edge 10R in the front-rear direction L may be displaced, and positions of the front end edge 10F and the rear end edge 10R may be displaced in a wound state. By shifting the positions of the front end edge 10F and the rear end edge 10R, the height difference of the rolled absorbent article can be reduced and the rolled absorbent article can be rolled more compactly than in a configuration in which the front end edge 10F and the rear end edge 10R are aligned.

In the folded state, the front end edge 10F and the rear end edge 10R of the absorbent article may be shifted in the front-rear direction L, and when the absorbent article 10 is rolled up from the 2 nd end edge 12 side, the end edge side located on the inner side in the front-rear direction L of the front end edge 10F and the rear end edge 10R of the absorbent article may be rolled up as the inner side. More specifically, when the front end edge 10F of the absorbent article is positioned further inward in the front-rear direction L than the rear end edge 10R, the absorbent article is rolled up so that the front end edge 10F of the absorbent article is positioned inward, and when the rear end edge 10R of the absorbent article is positioned further inward in the front-rear direction L than the front end edge 10F, the absorbent article is rolled up so that the rear end edge 10R of the absorbent article is positioned inward. With such a configuration, the positions of the front end edge 10F and the rear end edge 10R of the absorbent article 10 can be easily aligned in the rolled state. Therefore, the habitually rolled shape can be made to coincide at the front waistline region S1 and the back waistline region S2. Further, by bringing the front edge 10F and the rear edge 10R of the absorbent article 10 closer to each other in the rolled state, the following problems can be suppressed: one of the front end edge 10F and the rear end edge 10R of the absorbent article 10 is raised or bent by being excessively protruded from the other.

The absorbent article may be rolled up with the front waistline region S1 side inside. That is, in the rolled state, the front waistline region S1 may be positioned inward, and the back waistline region S2 may be positioned outward. When the front waistline region S1 side is turned up inward, the back waistline region S2 is positioned outward in the turned-up state, and the back waistline region S2 in the unfolded state is formed with a habitual turn-up along the skin side of the wearer in the unfolded state. The buttocks where leakage of excrement is likely to occur can be easily covered, and rear leakage can be suppressed.

In a state where the absorbent article 10 is rolled up, the nonwoven fabrics constituting the non-skin surface of the absorbent article 10 may abut against each other. In the rolled state of the absorbent article 10, the nonwoven fabrics positioned on the non-skin surface of the absorbent article are in contact with each other. The nonwoven fabric has a higher friction coefficient than the film, and the like, and the engagement state between the nonwoven fabrics is easily maintained. Therefore, the compactly rolled state is more easily maintained.

In the folded state, the absorbent article 10 may have a rolling start region R21 on the rolling start side and a rolling end region R22 on the rolling end side. The roll-up start region R21 is a region extending in the front-rear direction L over a certain range from the outer end edge of the 1 st end edge 11 and the 2 nd end edge 12 that serves as the roll-up start portion, and the roll-up end region R22 is a region extending in the front-rear direction L over a certain range from the outer end edge of the 1 st end edge 11 and the 2 nd end edge 12 that serves as the roll-up end portion. The length of the roll-up start region R21 in the front-rear direction L is the same as the length of the roll-up end region R22 in the front-rear direction L. Specifically, the rolling start region R21 and the rolling end region R22 may be regions extending 45mm from the outer end edge. The contraction force in the width direction W of the roll-up end region R22 may be higher than the contraction force in the width direction W of the roll-up start region R21. Since the rolling completion region R22 has a high contractive force, the rolling completion region R22 is in close contact with the inside in the rolled state, and the rolled state is easily maintained. In addition, the rolling completion region R22 is less likely to float in the rolled state, and the rolled state can be maintained more easily in a compact state. The winding end region R22 may be provided on the 1 st edge 11 (waist opening) side or on the 2 nd edge (width folding line FW) side.

The widthwise shrinkage force of the wind-up start region R21 and the widthwise shrinkage force of the wind-up end region R22 can be measured using an autosgraph type tensile tester (e.g., AG-1KN1 manufactured by shimadzu corporation). First, in a state where the absorbent article 10 is extended to such an extent that the gathers produced by the contraction action of the respective stretchable members disappear from the surface of the absorbent article 10, the dimensions (initial dimensions) in the width direction W of the rolling start region R21 and the rolling end region R22 are measured in advance, and then the rolling start region R21 and the rolling end region R22 are cut by a cutter to obtain a sample. Next, one end of each sample was clamped to a fixed chuck, the other end was clamped to a movable chuck, each sample was extended to a size of about 90% of the initial dimension at a speed of 300mm/min and then inverted, and the tensile load (N) when the sample contracted to a size of about 75% of the initial dimension was obtained, and the tensile load was converted into a stress value (N/mm) per unit width (mm) as a contraction force.

The length in the width direction W of the roll-up start region R21 may be shorter than the length in the width direction W of the roll-up end region R22. Since the length of the rolling start region R21 in the width direction W is short, the rolling start portion can be made small, and the entire body can be rolled up compactly. Further, since the length of the wind-up end region R22 in the width direction W is long, the entire wind-up end region having a wide width can be used to hold the wind-up end region in a wound-up state, and the wound-up state can be maintained more easily in a compact state.

Stretchable members stretchable in the width direction W may be disposed in the front waistline region S1 and the rear waistline region S2 of the absorbent article 10. The regions in contact with each other in the rolled state are likely to be in close contact with each other due to contraction of the stretchable member. Therefore, the compactly rolled state is more easily maintained.

The present invention has been described in detail with reference to the above embodiments, but it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and variations without departing from the spirit and scope of the present invention defined by the claims. Therefore, the description of the present specification is for illustrative purposes, and does not have any limiting meaning to the present invention.

In the above-described embodiment, only one width folding line FW is formed, but a plurality of width folding lines FW may be formed in a modification. In the embodiment having a plurality of width folding lines FW, one of the width folding lines may overlap the absorbent core in the crotch region. In addition, in the modification, the front and rear folding lines may be formed in more than one pair.
