Generally, the absorbent article attached to the inside of the worn article has an adhesive portion for preventing the absorbent article from slipping with respect to the worn article. This adhesive portion is provided on the surface (non-skin surface) of the absorbent article opposite to the skin surface side (the side facing the user's skin).

Patent Document 1 discloses an absorbent article in which the absorbent article is folded from a boundary folding portion extending in the width direction. The absorbent article is divided into a main body portion and an extendable portion with the boundary folding portion as a boundary. The extendable portion can extend outward in the front-rear direction from the main body portion.

International Publication No. 2016/032488

Since the worn article has a curved shape from the inseam to the waist, it is difficult to attach the absorbent article in a long state in the front-rear direction to the worn article at one time. Therefore, the inventor of the present application gradually attaches the absorbent article to the worn article by extending the extendable portion in a state where the absorbent article having a short length in the front-rear direction is fixed to the worn article. I thought about installing it.

However, since the absorbent article of Patent Document 1 can be used in a non-extended state in which the extendable portion is not extended, the user can use the non-extended absorbent article without discomfort. Therefore, there is a risk that the user may attach the absorbent article to the worn article without noticing the existence of the extendable portion, and the absorbent article may be used without being gradually attached to the worn article.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an absorbent article that makes it easy for the user to recognize the existence of the extendable portion.

The absorbent articles according to one embodiment include an anteroposterior direction, a width direction, a thickness direction, an absorber, a non-skin side sheet arranged on the non-skin surface side of the absorber, and the non-skin side. It has an adhesive portion provided on the non-skin surface of the sheet and having adhesiveness. It is folded with the boundary folding portion extending in the width direction as a base point. With the boundary folding portion as a boundary, it is divided into a main body portion and an extendable portion. The main body portion can be fixed to the worn article via the adhesive portion. The extendable portion can extend outward from the main body portion in the front-rear direction from the non-extended state folded back from the boundary folded portion as a base point. In the non-extended state, in the front-rear direction, from the boundary folded portion to the position farthest from the boundary folded portion among the portions where the main body portion and the extendable portion overlap in the thickness direction. There is an overlapping area between them. The absorbent article has an article outer edge that constitutes the widthwise outer shape of the absorbent article in the overlapping region in a plan view of the absorbent article in the non-extended state. In a plan view of the absorbent article in the non-extended state, at least one of the extendable portion and the main body portion arranged farthest from the main body portion on one side in the thickness direction is the said. It has an overlapping outer edge, which is an outer edge arranged inside the article outer edge in the width direction in the overlapping region.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.

The absorbent articles according to one embodiment include an anteroposterior direction, a width direction, a thickness direction, an absorber, a non-skin side sheet arranged on the non-skin surface side of the absorber, and the non-skin side. It has an adhesive portion provided on the non-skin surface of the sheet and having adhesiveness. It is folded with the boundary folding portion extending in the width direction as a base point. With the boundary folding portion as a boundary, it is divided into a main body portion and an extendable portion. The main body portion can be fixed to the worn article via the adhesive portion. The extendable portion can extend outward from the main body portion in the front-rear direction from the non-extended state folded back from the boundary folded portion as a base point. In the non-extended state, in the front-rear direction, from the boundary folded portion to the position farthest from the boundary folded portion among the portions where the main body portion and the extendable portion overlap in the thickness direction. There is an overlapping area between them. The absorbent article has an article outer edge that constitutes the widthwise outer shape of the absorbent article in the overlapping region in a plan view of the absorbent article in the non-extended state. In a plan view of the absorbent article in the non-extended state, at least one of the extendable portion and the main body portion arranged farthest from the main body portion on one side in the thickness direction is the said. It has an overlapping outer edge, which is an outer edge arranged inside the article outer edge in the width direction in the overlapping region.

Absorbent articles before use may have unintended wrinkles and / or creases. Therefore, the user can stroke the surface of the absorbent article from the center of the absorbent article toward the outside in the width direction, or grasp the side portion of the absorbent article and pull it outward in the width direction. Performs an action to remove wrinkles or breaks in an absorbent article.

Here, at least one overlapping outer edge of the extendable portion and the main body portion, which are arranged farthest from the main body portion, is arranged inside the outer edge of the article in the width direction. When removing wrinkles and / or folds of the absorbent article, the user touches a part inside the outer edge of the article, which makes it easier for the user to touch the overlapping outer edge, which gives the user a sense of discomfort. It is possible to make it easier for the user to recognize the existence of the extendable portion. In addition, since the thickness of the absorbent article changes between the inside and the outside in the width direction of the outer edge of the article, it is possible to give the user a sense of discomfort and make it easier for the user to recognize the existence of the extendable portion. it can.

According to a preferred embodiment, the extendable portion may be folded with the auxiliary folding portion extending in the width direction as a base point. The extendable portion is a first portion that is a portion from the boundary folding portion to the auxiliary folding portion, and a second portion that is a portion from the auxiliary folding portion to the outer edge of the absorbent article in the front-rear direction. May have a portion and. In the non-extended state, the second portion may overlap the first portion and the main body portion in the thickness direction. As a result, there is a difference in thickness between the portion where the second portion overlaps the first portion and the main body portion in the thickness direction and the portion where only the main body portion exists. This makes it easier for the user to notice the difference in thickness when removing wrinkles and / or folds of the absorbent article and to make the user aware of the presence of the extendable portion.

According to a preferred embodiment, the outer edge of the main body may be the outer edge of the article. The outer edge of the second portion may be the overlapping outer edge. In a plan view of the absorbent article, the outer edge of the first portion may be arranged between the outer edge of the article and the overlapping outer edge in the width direction.

This makes it easier for the user to touch the outer edge of the first portion in addition to the overlapping outer edge (ie, the outer edge of the second portion) when removing wrinkles and / or folds in the absorbent article. This makes it easier for the user to feel uncomfortable, and makes it easier for the user to recognize the existence of the extendable portion. Also, in the overlapping region, the thickness of the absorbent article changes stepwise from the inside to the outside in the width direction. This makes it easier for the user to feel uncomfortable, and makes it easier for the user to recognize the existence of the extendable portion.

According to a preferred embodiment, the outer edge of the main body may be the outer edge of the article. The outer edge of the second portion may be the overlapping outer edge and extend outward from the boundary folding portion in the front-rear direction. In the plan view of the absorbent article, the outer edge of the second portion may be arranged inside the outer edge of the main body portion in the width direction on the boundary folding portion.

As a result, the outer edge of the second portion is arranged so as to be displaced inward in the width direction from the outer edge of the main body portion with the boundary folding portion as a boundary, so that the user is likely to feel a sense of discomfort visually. This makes it easier for the user to recognize the existence of the extendable portion.

According to a preferred embodiment, the absorbent article has a first fold portion and a second fold portion extending in the width direction formed by folding the absorbent article together with a packaging sheet for individually wrapping the absorbent article. Good. The extendable portion may have one outer edge of the absorbent article in the anteroposterior direction. The first fold may be the fold closest to the other outer edge of the absorbent article in the anteroposterior direction. The second fold portion may be a fold portion near the other outer edge after the first fold portion. The second fold may be located closer to the other outer edge than the auxiliary fold.

As a result, when the absorbent article is unfolded in the front-rear direction from the state in which the absorbent article is folded with the second folded portion as the base point, the user can easily touch the extendable portion, so that the absorbent article can be extended to the user. It is possible to make it easier to recognize the existence of the part.

According to a preferred embodiment, the outer edge of the main body may be the outer edge of the article. The outer edge of the extendable portion may be the overlapping outer edge. In the non-extended state, the extendable portion may be arranged closer to the skin surface than the main body portion.

As a result, the user can visually recognize the overlapping outer edges, and can easily make the user recognize the existence of the extendable portion.

According to a preferred embodiment, in the overlapping region, the tactile sensation of the region inside the overlapping outer edge in the width direction and the tactile sensation of the region outside the overlapping outer edge in the width direction may be different.

As a result, when the user removes wrinkles and / or folds of the absorbent article, the difference in tactile sensation gives the user a tactile discomfort, and makes it easier for the user to recognize the existence of the extendable portion. Can be done.

According to a preferred embodiment, the absorbent article is arranged on both sides of the central region and the central region by dividing the maximum width of the portion arranged on the skin surface side of the worn article into three equal parts when the absorbent article is worn. A side area and a side area may be provided. The overlapping outer edges may be located in the side area.

This touches the overlapping outer edges located in the side areas when the user grabs the sides of the absorbent article and pulls outward in the width direction to remove wrinkles and / or folds in the absorbent article. It will be easier. This makes it easier for the user to feel uncomfortable, and makes it easier for the user to recognize the existence of the extendable portion.

According to a preferred embodiment, the extendable portion may be arranged on the rear side of the main body portion and may be extendable to the rear. The tactile sensation of the non-skin side sheet of the main body portion and the tactile sensation of the non-skin side sheet of the extendable portion may be different.

As a result, the user can recognize the difference between the main body portion and the extendable portion by the tactile sensation of the non-skin side sheet. It is possible to make it easier for the user to recognize the existence of the extendable portion.

According to a preferred embodiment, the absorbent article is in an unfolded state in which a packaging sheet for individually packaging the absorbent article is unfolded and in the non-extended state, and the extendable portion is the packaging sheet and the packaging sheet. It may have an facing surface facing any of the extension regions located outside in the front-rear direction from the outer edge of the packaging sheet. The adhesive portion may be provided in a region other than the facing surface.

When the main body is fixed to the worn article in the non-extended state, the facing surface of the extendable portion faces the worn article. Here, since the adhesive portion is provided in a region other than the facing surface of the extendable portion, the adhesive portion is not provided on the facing surface itself. Therefore, in the non-extended state, the extendable portion is not fixed to the worn article via the adhesive portion. As a result, the user can easily pull out the extendable portion while the main body portion is fixed to the worn article.

According to a preferred embodiment, the extendable portion may be arranged on the rear side of the main body portion and may be extendable to the rear. The absorbent article may have wings that fold back to the non-skin side of the worn article. In the non-extended state, the extendable portion may be arranged behind the rear end of the wing. This makes it easier for the extendable portion to be placed behind the user. The user can easily grasp the extendable portion from the rear side of the user in a state where the wearable article to which the absorbent article is attached is passed through the leg, so that the extendable portion can be easily extended.

According to a preferred embodiment, the boundary folding portion may be provided with a bending guiding portion extending in the width direction and inducing bending of the absorber.

In the bending guide portion, since the absorber is induced to bend, it becomes easy to maintain the non-extended state in which the absorbent article is folded with the boundary folding portion and the auxiliary folding portion as the base points, and the main body portion is fixed to the worn article. It becomes easier to do.

According to a preferred embodiment, the main body may have an excretion port contact area including a region that contacts the user's excretion port. It may have a bending guide portion extending in the front-rear direction at the center in the width direction and inducing bending of the absorber. The bending guide portion may be arranged in the main body portion on the rear side of the center of the excretion port contact region in the front-rear direction.

The posterior side of the excretion opening contact area in the anterior-posterior direction tends to face the user's buttocks and / or perineum. When the bending guide portion faces the buttocks, the bending guide portion extending in the front-rear direction at the center in the width direction makes it easier for the highly rigid absorber to bend along the intergluteal cleft. As a result, the main body can be easily fitted to the buttocks, and the leakage of excrement can be suppressed. Further, when the bending guide portion faces the perineal portion, the bend guiding portion also makes it easier for the absorber to bend in the perineal portion. As a result, the main body portion can be easily fitted to the perineal portion, and the leakage of excrement can be suppressed.

(2) Schematic configuration of the absorbent article 10 Hereinafter, the absorbent article according to the first embodiment will be described with reference to the drawings. The absorbent article may be an absorbent article such as a sanitary napkin, panty liner, adult incontinence pad or urine absorbing pad. In the following embodiments, disposable sanitary napkins will be described as an example of an absorbent article.

FIG. 7 is a schematic cross-sectional view taken along the line F7-F7 of FIG. In the schematic cross-sectional view, for convenience of explanation, the members may be separated in the thickness direction T, but in the actual product, they are in contact with the thickness direction T.

In the present specification, the "non-extended state" is a state in which the extendable portion 70 described later is folded back from the boundary folding portion BFL described later as a base point. In the non-extended state, the extendable portion 70 is not extended. The absorbent article 10 in FIGS. 1 and 2 is in a non-extended state. On the other hand, the "extended state" is a state in which the extendable portion 70 is not folded back from the boundary folding portion BFL as a base point. In the extended state, the extendable portion 70 is extended. The absorbent article 10 in FIGS. 3 and 4 is in an extended state.

The absorbent article 10 has a front-rear direction L, a width direction W, and a thickness direction T. The anteroposterior direction L is a direction extending from the front side (ventral side) of the user to the rear side (dorsal side), or a direction extending from the rear side of the user to the front side. The width direction W is a direction orthogonal to the front-rear direction L. The thickness direction T is a direction extending from the skin surface side of the user to the non-skin surface side (T2) or a direction extending from the non-skin surface side of the user to the skin surface side (T1). Further, the thickness direction T is a direction orthogonal to the front-rear direction L and the width direction W. The skin surface side corresponds to the side facing the user's skin at the time of use. The non-skin side corresponds to the side opposite to the skin side at the time of use, that is, the side facing away from the user's skin.

When the absorbent article 10 is divided into three equal parts in the front-rear direction L in the extended state, the absorbent article 10 has a front region S1 which is a front region, a rear region S2 which is a rear region, and a front region. It may have a central region S3 located between S1 and the rear region S2.

The absorbent article 10 is configured to be individually wrapped by the packaging sheet 100. The packaging body 1 is formed by packaging the absorbent article 10 in the packaging sheet 100 (see FIG. 8A). The packaging body 1 has an absorbent article 10 and a packaging sheet 100. As shown in FIG. 8A, in the state where the absorbent article 10 is packaged (packaging state), the absorbent article 10 and the packaging sheet 100 have the first folding portion FL1 and the second folding portion FL2 extending in the width direction W as base points. It is folded as. The first fold portion FL1 is the frontmost fold in the front-rear direction L, and the second fold portion FL2 is the front fold next to the first fold portion FL1 in the front-rear direction L.

The absorbent article 10 has a skin side sheet 20, a non-skin side sheet 25, an absorber 30, and an adhesive portion 50. The skin side sheet 20 is arranged on the skin surface side of the absorber 30. The skin side sheet 20 is a sheet that faces the user's skin and faces the user's skin. The skin side sheet 20 may be made of, for example, a liquid-permeable non-woven fabric.

The non-skin side sheet 25 is arranged on the non-skin surface side of the absorber 30. The non-skin side sheet 25 is a sheet that is directed to the worn article and faces the worn article. The non-skin side sheet 25 may be made of, for example, a liquid-impermeable synthetic resin film.

The absorber 30 may have an absorption core 30A containing an absorbing material that absorbs the liquid, and a core wrap 30B that encloses the absorbing core. In the embodiment, the core wrap 30B is arranged so as to sandwich the absorption core 30A in the thickness direction T. The absorbent material may be, for example, an absorbent material consisting of pulp, a highly absorbent polymer, or a mixture thereof. The core wrap 30B may be made of, for example, a tissue or a non-woven fabric. The absorber 30 may be composed of only the absorption core 30A without having the core wrap 30B.

The absorber 30 may continuously extend in the front-rear direction L from the front side region S1 to the rear side region S2. In the present embodiment, the core wrap 30B continuously extends from the front side region S1 to the rear side region S2. The absorption core 30A may extend continuously from the front side region S1 to the rear side region S2. In the non-extended state, the absorbers 30 overlap in the thickness direction T, and in the extended state, the absorbers 30 do not overlap in the thickness direction T. In the extended state, since the absorbers 30 do not overlap each other in the thickness direction T, the locally high rigidity portion disappears, and the deterioration of the wearing comfort of the absorbent article 10 can be suppressed.

The absorber 30 may have a first absorber 31 and a second absorber 32. The first absorber 31 is arranged on the center side in the width direction W. The second absorber 32 is arranged on the end side in the width direction W. The second absorber 32 is arranged so as to sandwich the first absorber 31 in the width direction W. The first absorber 31 and the second absorber 32 may extend in the front-rear direction L. The second absorber 32 may be provided apart from the first absorber 31.

In the present embodiment, the first absorber 31 is composed of an absorption core 30A and a core wrap 30B. The second absorber 32 is composed of an absorption core 30A.

The adhesive portion 50 is provided on the non-skin surface of the non-skin side sheet 25 and has adhesiveness. In the embodiment, the adhesive portion 50 is provided in a region other than the facing surface 75, which will be described later, in the non-extended state.

The adhesive portion 50 includes a main body adhesive portion 51 provided on the non-skin surface of the main body portion 11 (non-skin side sheet 25) described later and a non-skin portion of the extendable portion 70 (non-skin side sheet 25) described later. It may have an extended adhesive portion 52 provided on the surface. The main body adhesive portion 51 may have an adhesive portion 511 provided at a position overlapping the first absorber 31 in the thickness direction T. The main body adhesive portion 51 may have an adhesive portion 512 provided at a position overlapping with the second absorber 32 in the thickness direction T.

The extending adhesive portion 52 may be provided in a region (appropriately referred to as an overlapping region) in which the first portion 71 described later and the second portion 72 described later overlap in the thickness direction T in the non-extended state. In the embodiment, as shown in FIG. 4, the extension adhesive portion 52 is provided in the second portion 72. Further, the extension adhesive portion 52 is provided in a region other than the facing surface 75. Therefore, as shown in FIG. 2, the extended adhesive portion 52 is not directly visible when viewed from the non-skin surface side of the absorbent article 10 in the non-extended state. In the non-extended state, the extended adhesive portion 52 is arranged between the first portion 71 and the second portion 72.

The absorbent article 10 may be provided with a peeling portion 58. The peeling portion 58 protects the adhesiveness of the adhesive portion 50, and is a portion where the adhesive portion 50 can be easily peeled off. The peeling portion 58 can be made of, for example, a paper, a film, or a non-woven fabric that has been subjected to a mold release treatment that enables peeling. For example, the peeling portion 58 may be formed of a sheet in which a polyethylene film is coated with a silicone resin.

When the extension adhesive portion 52 is provided on one of the first portion 71 and the second portion 72 in the overlapping region, the peeling portion 58 is provided on the other side of the first portion 71 and the second portion 72 in the overlapping region. It may be provided. The peeling portion 58 may cover the extending adhesive portion 52 provided on the extendable portion 70 in the non-extending state. As a result, it does not come into contact with the non-skin side sheet 25 of the first portion 71.

Further, the area of the peeling portion 58 may be larger than the area of the extending adhesive portion 52. In the non-extended state, the rear end portion of the peeling portion 58 may be arranged behind the rear end portion of the extending adhesive portion 52 in the front-rear direction L (see FIG. 6B).

The absorbent article 10 is provided with a temporary fixing portion 60 for temporarily fixing the main body portion 11 and the extendable portion 70. The temporary fixing portion 60 temporarily fixes the main body portion 11 and the first portion 71, which will be described later, in the non-extended state.

A pair of temporary fixing portions 60 may be provided apart from the center Wc of the absorbent article 10 in the width direction W in the width direction W. As shown in FIG. 1, the pair of temporary fixing portions 60 may be arranged so as to sandwich the center Wc. The distances from each of the pair of temporary fixing portions 60 to the center Wc may be substantially the same. The pair of temporary fixing portions 60 may be arranged on a straight line extending in the width direction W. Here, when the user pulls out the extendable portion 70 to the outside of the front-rear direction L, it is arranged on a straight line extending in the width direction so that the force acts substantially evenly on the pair of temporary fixing portions 60. I just need to be there. Therefore, in the plan view of the absorbent article 10, the positions of the pair of temporary fixing portions 60 in the front-rear direction L may be the same as each other or may be slightly deviated from each other. For example, the length of the front-rear direction L from one temporary fixing portion 60 to the other temporary fixing portion 60 may be within the thickness of the absorbent article 10 (for example, 10 mm).

As shown in FIG. 7, the temporary fixing portion 60 temporarily fixes the first portion 71 and the second portion 72 in addition to the temporary fixing of the main body portion 11 and the first portion 71. Therefore, the temporary fixing portion 60 may temporarily fix the main body portion 11, the first portion 71, and the second portion 72 together.

The temporary fixing portion 60 may be arranged in the low basis weight region in the thickness direction T. Here, the "low basis weight region" is a region in which the absorber 30 is not arranged, or a region in which the absorber 30 is arranged and has a lower basis weight than the surrounding area.

In the present specification, as illustrated in Japanese Patent Application Laid-Open No. 2012-235809, the "temporary fixing" is not peeled off during manufacturing and transportation, but is joined to such an extent that it can be peeled off by hand during use. It means that. The joining by temporary fixing indicates that the absorbent article 10 is joined at a strength lower than the breaking strength of the absorbent article and is joined without being peeled off when the absorbent article 10 is opened from the packed state. The joint strength of the temporary fixing is preferably weaker than the joint strength of the adhesive portion 50 with respect to the worn article.

The temporary fixing portion 60 can be formed by pressurization and / or heating by embossing or sonic treatment. For example, in the case of embossing, the temporary fixing portion 60 can be formed by pressurizing or / or heating the portion where the temporary fixing portion 60 should be formed with a pin in the thickness direction. In the case of sonic treatment, the temporary fixing portion 60 is formed by sandwiching the product between the transmitter and the anvil and welding the resin with ultrasonic waves.

Further, in the case of temporarily fixing with an adhesive material, if the skin and the adhesive material rub against each other, skin troubles may occur. Therefore, it is preferable that the non-skin surface sides are joined to each other. When temporarily fixing with the adhesive material, it is preferable that the adhesive material for temporary fixing is a member different from the adhesive material for the adhesive portion 50. For example, it is preferable to select a material having physical properties that make re-adhesion difficult and / or a material having low tackiness as the pressure-sensitive adhesive material for the temporary fixing portion 60. The temporary fixing portion 60 may be an adhesive such as a hot melt adhesive.

As shown in FIGS. 1 and 2, the absorbent article 10 is folded in the unfolded state with the boundary folding portion BFL extending in the width direction W as a base point. The "unfolded state" is a state in which the packaging sheet 100 is unfolded. Therefore, the unfolded state is a state in which the packaging sheet 100 is not folded with the first folded portion FL1 and the second folded portion FL2 extending in the width direction W as the base points.

The packaging sheet 100 may be composed of only one sheet. In this case, the packaging sheet 100 may be a sheet that can be peeled off from the adhesive portion 50. Alternatively, the packaging sheet 100 may be composed of a first sheet and a second sheet arranged between the first sheet and the absorbent article 10. The first sheet may be made of, for example, a non-woven fabric. The second sheet may be a sheet that can be peeled off from the adhesive portion 50. The first sheet and the second sheet may be joined. As a result, by peeling the first sheet from the absorbent article 10, in addition to the first sheet, the second sheet may also be peeled from the absorbent article 10.

The absorbent article 10 is divided into a main body portion 11 and an extendable portion 70 with the boundary folding portion BFL as a boundary.

The main body portion 11 can be fixed to the worn article via the adhesive portion 50 (main body adhesive portion 51). Specifically, in the non-extended state, the main body portion 11 can be fixed to the worn article by being attached to the worn article (for example, underwear). The main body 11 may include a skin side sheet 20, a non-skin side sheet 25, and an absorber 30.

The main body 11 may be a region including the center Lc of the absorbent article 10 in the front-rear direction L in the extended state. Further, the main body portion 11 may be a region including the center Lfc of the absorbent article 10 in the front-rear direction L in the non-extended state. The main body portion 11 may have a front main body portion 11F arranged on the front side of the center Lfc in the front-rear direction L in the non-extended state, and a rear main body portion 11R arranged on the rear side of the center Lfc. The absorber 30 may be arranged on the front main body portion 11F. The absorber 30 may be arranged on the rear main body portion 11R.

The main body 11 may have an excretion port contact area ER including an area that contacts the user's excretion port. The absorbent article 10 does not have a wing 15 that is folded back to the non-skin surface side of the worn article U, and the absorbent article 10 is based on two folds (first fold portion FL1 and second fold portion FL2). When folded and housed together with the packaging sheet 100, the excretion port contact area ER is a region from the first folded portion FL1 to the second folded portion FL2 in the front-rear direction L (see FIGS. 1 and 3). ..

When the absorbent article 10 is folded and accommodated together with the packaging sheet 100 with the three folded portions as the base points, the excretion port contact area ER is from the frontmost folded portion to the next front folded portion. The area. When the wing 15 is provided, the excretion opening contact area ER is a region from the front end of the wing 15 (the base on the front side of the wing) to the rear end of the wing 15 (the base on the rear side of the wing 15).

The extendable portion 70 is a portion that is folded back from the boundary folding portion BFL as a base point in the non-extended state. The extendable portion 70 can extend from the non-extendable state to the outside of the main body portion 11 in the front-rear direction L. In the present embodiment, the extendable portion 70 can extend backward.

The extendable portion 70 may include at least the skin side sheet 20 and the non-skin side sheet 25. The extendable portion 70 may include an absorber 30.

The tactile sensation of the non-skin side sheet 25 of the main body portion 11 and the tactile sensation of the non-skin side sheet 25 of the extendable portion 70 may be different. For example, the non-skin side sheet 25 of the main body portion 11 may be made of a synthetic resin film, and the non-skin side sheet 25 of the extendable part 70 may be made of a non-woven fabric. Further, among the non-skin side sheets 25 of the extendable portion 70, the tactile sensation of the facing surface 75 may be different from the tactile sensation of the non-skin side sheet 25 of the main body portion 11. Of the non-skin side sheet 25 of the extendable portion 70, the tactile sensation other than the facing surface 75 may be the same as the tactile sensation of the non-skin side sheet 25 of the main body portion 11, or may be different.

In the unfolded state, the extendable portion 70 may be folded with the auxiliary folding portion SFL extending in the width direction W as a base point. Therefore, the absorbent article 10 may be diffracted twice. The extendable portion 70 may have a first portion 71 and a second portion 72. The first portion 71 is a portion extending inward in the front-rear direction L from the boundary folding portion BFL. The first portion 71 may be a portion from the boundary folding portion BFL to the auxiliary folding portion SFL. The second portion 72 is a portion extending outward from the auxiliary folding portion SFL in the front-rear direction L. The second portion 72 may be a portion from the auxiliary folding portion SFL to the outer edge of the absorbent article 10 in the front-rear direction L.

As shown in FIGS. 1, 2, 6B, and 7, in the non-extended state, the first portion 71 may be arranged on the skin surface side T1 of the main body portion 11, and the second portion 72 is the second portion. It may be arranged on the skin surface side T1 rather than the one portion 71. Therefore, the extendable portion 70 is a portion of the main body portion 11 that is folded toward the skin surface side.

In the present embodiment, the extendable portion 70 arranged on one side of the thickness direction T farthest from the main body portion 11 is the second portion 72. In the non-extended state, the second portion 72 overlaps the first portion 71 and the main body portion 11 in the thickness direction T.

The absorbent article 10 is folded so that the skin-side sheet 20 of the main body 11 and the skin-side sheet 20 of the first portion 71 face each other with the boundary folding portion BFL as a base point. The boundary fold portion BFL corresponds to a fold portion that is folded into a valley fold when viewed from the skin surface side. Further, the absorbent article 10 is folded so that the non-skin side sheet 25 of the first portion 71 and the non-skin side sheet 25 of the second portion 72 face each other with the auxiliary folding portion SFL as a base point. The auxiliary fold SFL corresponds to a fold that is folded into a mountain fold when viewed from the skin surface side.

As shown in FIG. 1, the first portion 71 may have a portion not covered by the second portion 72 in the non-extended state when viewed from the skin surface side of the absorbent article 10. The non-skin side sheet 25 of the first portion 71 may be exposed from the second portion 72. Therefore, the first portion 71 may have a region that does not overlap with the second portion 72 in the thickness direction T. In the non-extended state, the area of the first portion 71 between the boundary fold portion BFL and the auxiliary fold portion SFL when viewed from the skin surface side of the absorbent article 10 is the area of the boundary fold portion BFL and the auxiliary fold portion SFL. It may be larger than the area of the second portion 72 in between.

In the present embodiment, the extendable portion 70 has an facing surface 75 facing the packaging sheet 100 in the unfolded state and the non-extended state. The facing surface 75 faces the worn article U when the main body 11 is fixed to the worn article U in the non-extended state. In FIG. 4, the second portion 72 has an facing surface 75 facing the packaging sheet 100. The facing surface 75 is the surface of the non-skin side sheet 25 in the second portion 72.

The absorbent article 10 may have a bending guiding portion 80 that induces bending of the absorber 30. The bending guide portion 80 makes it easier for the highly rigid absorber 30 to bend. Therefore, the bending guide portion 80 is provided in the region where the absorber 30 is arranged. The absorber 30 may be arranged in the extendable portion 70. Specifically, the absorber 30 may be arranged in the first portion 71, or may be arranged in the second portion 72.

In the present embodiment, the bending guide portion 80 is provided by making the basis weight of the absorber 30 lower than that of the surroundings. Specifically, in the plan view of the absorbent article 10, the bending guide portion 80 is a region in which the first absorber 31 is arranged, in which the absorption core 30A is not arranged. The bending guide portion 80 may be formed, for example, by providing a slit penetrating the absorption core 30A.

Further, the thickness of the bending guide portion 80 may be different from the thickness around the bending guidance portion 80. In the embodiment, since the absorption core 30A is not arranged in the bending guidance portion 80, the thickness of the bending guidance portion 80 becomes thinner than the circumference of the bending guidance portion 80 by the thickness of the absorption core 30A. There is.

The bending guiding portion 80 may have a front-rear guiding portion 80L extending in the front-rear direction L at the center of the width direction W and a width guiding portion 80W extending in the width direction W. The front-rear guiding portion 80L induces bending of the absorber 30 (first absorber 31) along the front-rear direction L. The front-rear guide portion 80L may extend on the center (center line) Wc in the width direction W. The width guiding portion 80W induces bending of the absorber 30 (first absorber 31) along the width direction W. The width guiding portion 80W may extend from one outer edge of the width direction W of the first absorber 31 to the other outer edge.

The "center of the width direction W" in which the front-rear guiding portion 80L extends is the central region when the absorbent article 10 is divided into three equal parts in the width direction W. However, when the absorbent article 10 has wings, it is a region obtained by dividing the region excluding the wings into three equal parts in the width direction W. Therefore, the "center of the width direction W" is the center (central portion) of the absorbent body located on the skin surface side of the worn article while being fixed to the worn article, divided into three equal parts in the width direction W. .. Hereinafter, the center of the width direction W may be referred to as a central portion of the width direction W.

The front-rear guidance portion 80L may have a main body front-rear guidance portion 81L provided in the main body portion 11 and an extension front-rear guidance portion 87L provided in the extendable portion 70.

That is, the main body front-rear guidance portion 81L may be arranged behind the center ERc of the excretion port contact region ER in the front-rear direction L. The front-rear guide portion 81L of the main body may extend so as to straddle the first folding portion FL1. The front-rear guide portion 81L of the main body may extend continuously to the boundary bending guide portion 85W across the first folding portion FL1.

The front-rear guidance portion 81L of the main body may be arranged in the central region S3. The main body front-rear guidance portion 81L may be arranged on the rear main body portion 11R. The front-rear guide portion 81L of the main body may extend to the center Lc of the front-rear direction L in the extended state, or may extend so as to straddle the center Lc. Further, the front-rear guiding portion 81L of the main body may extend to the boundary bending guiding portion 85W described later. This makes it easier for the boundary bending guide portion 85W to face the user's buttocks and / or perineum.

Further, the main body front-rear guidance portion 81L does not have to extend to the center Lfc of the front-rear direction L in the non-extended state. This makes it difficult for the front-rear guide portion 81L of the main body to face the excretion port (specifically, the vaginal opening). It is possible to prevent excrement (menstrual blood) from reaching the side sheet 25. The front-rear guidance portion 81L of the main body does not have to extend to the center Lc of the front-rear direction L in the extended state.

The width of the main body front-rear guiding portion 81L may be shorter than the width obtained by dividing the center of the width direction W into three equal parts in the width direction W. The width of the front-rear guide portion 81L of the main body is preferably 10 mm or less, and more preferably 5 mm or less. As a result, even if the front / rear guide portion 81L of the main body is a slit, it is possible to prevent excrement (menstrual blood) from reaching the non-skin side sheet 25 through the front / rear guide portion 81L of the main body.

In the plan view of the absorbent article 10, the extension front-rear guide portion 87L may be arranged between the pair of temporary fixing portions 60. Further, in the plan view of the absorbent article 10, the extension front-rear guidance portion 87L may be connected to the main body front-rear guidance portion 81L. This makes it easier for the bending guide 80 to continuously extend from the position facing the perineum to the position facing the buttocks. Therefore, the first absorber 31 can easily fit into the perineum and the buttocks, and the leakage of excrement can be suppressed.

The extension front-rear guidance portion 87L may have a first front-rear guidance portion 871L provided in the first portion 71 and a second front-rear guidance portion 872L provided in the second portion 72.

The first front-rear guiding portion 871L may extend from the boundary bending guiding portion 85W to the extended bending guiding portion 87W described later. The second front-rear guiding portion 872L may extend rearward from the extending bending guiding portion 87W. The second anterior-posterior guide portion 872L does not have to extend to the trailing edge of the first absorber 31. In the plan view of the absorbent article 10, the first front-rear guiding portion 871L and the second front-rear guiding portion 872L may be connected to each other.

The width guiding portion 80W may have a boundary bending guiding portion 85W provided in the boundary folding portion BFL and an extending bending guiding portion 87W provided in the extendable portion 70.

The boundary bending guide portion 85W may extend in the width direction W along the boundary folding portion BFL. The extension bending guide portion 87W may extend in the width direction W along the auxiliary folding portion SFL.

In the non-extended state, the length from the center ERc of the excretion port contact area ER in the anteroposterior direction L to the trailing edge of the extendable portion 70 is absorbed from the center ERc of the excretion port contact area ER in the anteroposterior direction L. It may be longer than the length to the front edge of the sex article 10.

The absorber 30 may be joined to the skin side sheet 20. Specifically, at least in the central portion in the width direction W, the absorber 30 in the main body portion 11 continuously extends from the front end of the main body front-rear guiding portion 81L to the rear end of the absorber 30 in the main body portion 11. May be joined to. Further, at least in the central portion in the width direction W, the absorber 30 in the first portion 71 may be continuously joined from the front end to the rear end of the extension front-rear guidance portion 87L (second front-rear guidance portion 872L). Further, at least in the central portion in the width direction W, the skin side sheet 20 may be continuously joined from the front end of the absorber 30 in the second portion 72 to at least the rear end of the front-rear guide portion 80L. The absorber 30 may be joined in a region other than the central portion of the skin side sheet 20. Further, the absorber 30 may be joined to the skin side sheet 20 on the front side of the front end of the front / rear guide portion 81L of the main body, or may be joined on the rear side of the rear end of the front / rear guide portion 80L.

In the non-extended state, an overlapping region OR is provided. The overlapping region OR is between the boundary folding portion BFL in the front-rear direction L and the portion farthest from the boundary folding portion BFL among the portions where the main body portion 11 and the extendable portion 70 overlap in the thickness direction T. The area. In the present embodiment, of the portions (overlapping portions) where the main body portion 11 and the extendable portion 70 overlap in the thickness direction T, the position farthest from the boundary folding portion BFL is the auxiliary folding portion SFL. Therefore, the overlapping region OR is a region between the boundary folding portion BFL and the auxiliary folding portion SFL in the front-rear direction L.

In a plan view of the absorbent article 10 in the non-extended state, the absorbent article 10 has an article outer edge 10E that constitutes the outer shape of the absorbent article 10 in the width direction W in the overlapping region OR. In the embodiment, the article outer edge 10E is the outer edge 11E of the main body 11. As shown in FIG. 1, in the overlapping region OR, the extendable portion 70 has an outer edge 70E arranged inside the outer edge 11E of the main body portion 11 in the width direction W. The outer edge 70E of the extendable portion 70 has an outer edge 71E of the first portion 71 and an outer edge 72E of the second portion 72.

In the present specification, the "outer edge" is an edge extending in the front-rear direction L, and is an edge inclined by 45 degrees or more with respect to the width direction W in the plan view of the absorbent article 10. Therefore, the "outer edge" is different from the edge extending in the width direction W.

In the embodiment, the second portion 72 is arranged on one side (skin surface side T1) of the thickness direction T farthest from the main body portion 11. In a plan view of the absorbent article 10 in the non-extended state, the second portion 72 has an overlapping outer edge OSE that is located inside the article outer edge 10E in the width direction W in the overlapping region OR. Therefore, the outer edge 72E of the second portion 72 is an overlapping outer edge OSE. The outer edge 71E of the first portion 71 may be arranged between the article outer edge 10E and the overlapping outer edge OSE in the width direction W.

As shown in FIG. 7, the overlapping region OR may have a first overlapping region OR1, a second overlapping region OR2, and a third overlapping region OR3. When the absorbent article 10 in the extended state, that is, the portion from the skin side sheet 20 to the non-skin side sheet 25 in the thickness direction T is regarded as one layer, the first overlapping region OR1 is one layer. The second overlapping region OR2 is a region composed of two layers, and the third overlapping region OR3 is a region composed of three layers. The first overlapping region OR1 may be composed of the main body 11. The second overlapping region OR2 may be composed of a main body portion 11 and a first portion 71. The third overlapping region OR3 may be composed of a main body portion 11, a first portion 71, and a second portion 72.

The second folding portion FL2 may be arranged closer to the front end edge 10F than the auxiliary folding portion SFL.

(3) Example of Attaching Absorbent Article 10 Next, an example of attaching the absorbent article 10 will be described with reference to FIGS. 1 to 12.

8 to 11 are schematic views for explaining an example of how to attach the absorbent article according to the embodiment. FIG. 8A is a schematic perspective view of the package according to the embodiment. FIG. 8B is a diagram for explaining that the package is unfolded. FIG. 8C is a schematic view showing an unfolded state of the package according to the embodiment. 9A and 9B are diagrams showing an example of an operation of removing wrinkles and / or folds contained in the absorbent article according to the embodiment. FIG. 9C is a schematic view showing a state in which the absorbent article (main body portion) according to the embodiment is fixed to the worn article. 10A to 10C are schematic views showing a transition from a non-extended state to an extended state in the absorbent article according to the embodiment. Note that FIG. 10 shows an example of a case in which the extendable portion 70 is extended after the user wears the worn article U. FIG. 11A is a schematic cross-sectional view showing an absorbent article in a state in which the user wears the worn article U and is in a non-extended state. FIG. 11B is a schematic cross-sectional view showing an absorbent article in a state in which the user is wearing the worn article U and in an extended state. FIG. 11C is a schematic cross-sectional view taken along the line F11C-F11C of FIG. 11B. In FIG. 11, BL indicates the line of the user's body, and CBL indicates the line of the center of the user's body. FIG. 12 is a schematic view for explaining the force applied when extending the extendable portion according to the embodiment. FIG. 12A is a schematic plan view of the absorbent article according to the embodiment as viewed from the skin surface side in the non-extended state. FIG. 12B is a schematic perspective view of the extendable portion as seen from the skin surface side in the non-extended state.

Since the worn article U has a curved shape from the inseam to the waist, the angle of the worn article U changes abruptly toward the waist side. Therefore, even if the user tries to attach the absorbent article 10 long in the front-rear direction L at a time, it is difficult to properly attach the absorbent article 10 along the worn article U. If the absorbent article 10 is not properly attached to the worn article U, excrement may leak easily. Further, if the absorbent article 10 is peeled off from the worn article U and reattached, it takes time to attach the absorbent article 10. In addition, since the adhesive portion 50 is peeled off from the worn article, the adhesive strength of the adhesive portion 50 is lowered, and the absorbent article 10 may be displaced during wearing. On the other hand, the absorbent article 10 which does not have the extendable portion 70 and is short in the front-rear direction L is easy to attach to the worn article U, but has a problem that the absorption performance tends to be low.

Therefore, the present inventor has found a new mounting method in which the absorbent article 10 is gradually attached to the worn article U as shown below.

First, the user develops the packaging sheet 100 of the packaging body 1. As a result, the absorbent article 10 in the unfolded state shown in FIG. 8B is obtained. In the unfolded state, the absorbent article 10 of FIG. 8C is folded with the boundary folding portion BFL as the base point, while the packaging sheet 100 is not folded with the folding portion extending in the width direction W as the base point. Therefore, in a state where the packaging sheet 100 is completely unfolded in the front-rear direction L, the absorbent article 10 is folded at least with the boundary folding portion BFL as a base point. Therefore, the absorbent article 10 is in a non-extended state. In addition, the absorbent article 10 may be folded with the auxiliary folding portion SFL as a base point.

As shown in FIG. 8C, the second folded portion FL may be arranged closer to the front edge 10F of the absorbent article 10 than the auxiliary folded portion SFL. As a result, as shown in FIG. 8B, when the absorbent article 10 is unfolded in the front-rear direction L from the state where the absorbent article 10 is folded from the second folded portion FL2 as a base point, the user can extend the extendable portion 70. Therefore, it is possible to make it easier for the user to recognize the existence of the extendable portion 70.

Second, the user peels off the packaging sheet 100 from the absorbent article 10 and fixes the absorbent article 10 to the worn article U (first step).

Here, the absorbent article 10 before use may have unintended wrinkles and / or folds. Therefore, the user strokes the surface of the absorbent article 10 from the center of the absorbent article 10 toward the outside in the width direction W (see FIG. 9A), or the side portion of the absorbent article 10 (side region SR). Is grabbed and pulled outward in the width direction W (see FIG. 9B) to remove wrinkles / breaks in the absorbent article 10.

In the absorbent article 10, the overlapping outer edge OSE is located inside the article outer edge 10E in the width direction W. When the user removes the wrinkles / folds of the absorbent article 10, the user touches the part inside the article outer edge 10E, which makes it easier for the user to touch the overlapping outer edge OSE, which gives the user a sense of discomfort. , It is possible to make it easier for the user to recognize the existence of the extendable portion 70. In addition, since the thickness of the absorbent article 10 changes between the inside and the outside of the width direction W of the article outer edge 10E, it gives a sense of discomfort to the user and makes the user recognize the existence of the extendable portion 70. It can be made easier.

Further, a portion where the second portion 72 overlaps the first portion 71 and the main body portion 11 in the thickness direction T (third overlapping region OR3) and a portion where only the main body portion 11 exists (first overlapping region OR1). , There is a difference in thickness. As a result, when removing wrinkles / folds, the user can easily notice the difference in thickness and make the user recognize the existence of the extendable portion 70.

Further, since the outer edge 71E of the first portion 71 is arranged between the article outer edge 10E and the overlapping outer edge OSE in the width direction W, the user can wrinkle and / or fold the absorbent article 10 times. In addition to the outer edge 72E of the second portion 72, the outer edge 71E of the first portion 71 becomes easier to touch when removing. This makes it easier for the user to feel uncomfortable, and makes it easier for the user to recognize the existence of the extendable portion 70. Further, in the overlapping region OR, the thickness of the absorbent article 10 changes stepwise from the inside to the outside in the width direction W. This makes it easier for the user to feel uncomfortable, and makes it easier for the user to recognize the existence of the extendable portion 70.

Further, on the boundary folding portion BFL, the outer edge 72E of the second portion 72 is arranged inside the outer edge 11E of the main body portion 11 in the width direction W. As a result, the outer edge 72E of the second portion 72 is arranged so as to be displaced inward in the width direction W from the outer edge 11E of the main body 11 with the boundary folding portion BFL as a boundary, so that the user can visually see it. It is easy to give a sense of discomfort. This makes it easier for the user to recognize the existence of the extendable portion 70.

Further, in the non-extended state, the extendable portion 70 is arranged on the skin surface side T1 of the main body portion 11, so that the user can visually recognize the overlapping outer edge OSE and use it. It is possible to make it easier for a person to recognize the existence of the extendable portion 70.

Further, in the overlapping region OR, the tactile sensation of the third overlapping region OR3 inside the overlapping outer edge OSE in the width direction W and the tactile sensation of the second overlapping region OR2 outside the overlapping outer edge OSE in the width direction W are different. Therefore, when the user removes the wrinkles / folds of the absorbent article 10, it is easy for the user to feel a sense of discomfort due to the difference in tactile sensation, and it is easy for the user to recognize the existence of the extendable portion 70. it can.

Further, when the user grabs the side portion (side region SR) of the absorbent article 10 and pulls it outward in the width direction W in order to remove the wrinkles / folds of the absorbent article 10, the absorbent article 10 is arranged in the side region SR. It becomes easier to touch the overlapping outer edge OSE. This makes it easier for the user to feel uncomfortable, and makes it easier for the user to recognize the existence of the extendable portion 70.

Further, the tactile sensation of the non-skin side sheet 25 of the main body portion 11 and the tactile sensation of the non-skin side sheet 25 of the extendable portion 70 are different, so that the user can differ between the main body portion 11 and the extendable portion 70. Can be recognized by the tactile sensation of the non-skin side sheet 25. It is possible to make it easier for the user to recognize the existence of the extendable portion 70.

Further, the absorbent article 10 is in a non-extended state and is in a short state in the front-rear direction L. Therefore, the user can easily peel off the packaging sheet 100 and fix the absorbent article 10 to the worn article U. Specifically, as shown in FIG. 9C, the user can fix the main body portion 11 in a region where the angle of the worn article U changes slowly. Therefore, the user can appropriately fix the main body portion 11 along the worn article U.

Further, since the extendable portion 70 is temporarily fixed to the main body portion 11 by the temporary fixing portion 60, the absorbent article 10 can easily maintain the non-extended state. This makes it easier to fix the main body 11 to the worn article U.

Further, since the boundary bending guide portion 85W (bending guidance portion 80) is provided in the boundary folding portion BFL, it becomes easy to maintain the state in which the absorbent article 10 is folded with the boundary folding portion BFL as a base point. Similarly, since the auxiliary folding portion SFL is provided with an extended bending guiding portion 87W (bending guiding portion 80), it is easy to maintain a state in which the absorbent article 10 is folded with the auxiliary folding portion SFL as a base point. Become. Therefore, the absorbent article 10 can easily maintain the non-extended state, and the main body 11 can be easily fixed to the worn article U.

Thirdly, the user extends the extendable portion 70 (second stage). The user can wear the worn article U to which the non-extended absorbent article 10 is fixed before extending the extendable portion 70 (see FIG. 11A). As shown in FIG. 10, after wearing the worn article U, the user can grasp the extendable portion 70 and pull out the extendable portion 70 to the outside (rearward) of the front-rear direction L.

Since the adhesive portion 50 is provided in a region other than the facing surface 75, the adhesive portion 50 is not provided on the facing surface 75 itself. Therefore, in the non-extended state, the extendable portion 70 is not fixed to the worn article U via the adhesive portion 50. As a result, the user can easily pull out the extendable portion 70 while the main body portion 11 is fixed to the worn article U.

Here, as shown in FIG. 12A, when the user grips the extendable portion 70 (specifically, the second portion 72) and pulls out the extendable portion 70 with the force F, the first portion 71 Is extended inward in the front-rear direction L from the boundary fold portion BFL, so that the first portion 71 is turned over with the boundary fold portion BFL as a fulcrum so as to extend outward in the front-rear direction L (see FIG. 10). Therefore, not only a force toward the outside in the front-rear direction L but also a force toward the outside in the thickness direction T tends to act on the first portion 71. The outward force in the thickness direction T is the direction (peel direction) in which the main body 11 and the first portion 71 are separated from each other in the thickness direction T in the temporary fixing portion 60 between the main body 11 and the first portion 71. ), The temporary fixing portion 60 can be removed by a peeling force. As a result, the temporary fixing portion 60 can be removed with a weaker force as compared with the case where the temporary fixing portion 60 is removed only by a shearing force. Therefore, the user can easily pull out the extendable portion 70 in a state where the non-extended absorbent article 10 is fixed to the worn article U.

Further, when the extendable portion 70 is gripped near the center Wc of the extendable portion 70 and the extendable portion 70 is pulled out by the force F, a force f6 toward the portion gripped by the user acts on the temporary fixing portion 60. Assume (see Figure 12A). Since the position of the width direction W in which the user grips the extendable portion 70 and the position of the width direction W of the temporary fixing portion 60 are different, the force f6 is a force component toward the outside (rear) of the front-rear direction L. In addition, it has a force component f6W that goes inward in the width direction W. The force component f6W causes the temporary fixing portion 60 to move inward in the width direction W so that the vicinity of the center Wc of the extendable portion 70, which is a portion not temporarily fixed by the temporary fixing portion 60, is separated from the main body portion 11. The extendable portion 70 (particularly near the auxiliary folding portion SFL) is deformed into an arch shape (see FIG. 12B). As a result, a peeling force acts from the inside of the width direction W of the temporary fixing portion 60 in the direction (peel direction) in which the main body portion 11 and the first portion 71 are separated from each other in the thickness direction T, so that the temporary fixing portion 60 is sheared. It can be removed with a weaker force than when it is removed only by shearing.

In the plan view of the absorbent article 10, the extension front-rear guide portion 87L is arranged between the pair of temporary fixing portions 60. Specifically, since the first portion 71 is provided with the first front-rear guiding portion 871L extending in the front-rear direction L as the bending guiding portion 80, the first portion 71 itself is easily bent and deformed into a convex shape. It becomes easier to do (see FIG. 12B). Further, since the second portion 72 is provided with the second front-rear guiding portion 872L extending in the front-rear direction L, the second portion 72 arranged on the skin surface side of the first portion 71 has a convex shape. It becomes easily deformed (see FIG. 12B). By deforming the second portion 72 into a convex shape, it becomes difficult to prevent the deformation of the first portion 71 into a convex shape. Therefore, a force in the direction in which the main body portion 11 and the first portion 71 are separated from each other in the thickness direction T is more likely to act inside the width direction W of the temporary fixing portion 60, and the temporary fixing portion 60 is removed by the peeling force. be able to. Therefore, the temporary fixing portion 60 can be removed with a weaker force as compared with the case where the temporary fixing portion 60 is removed only by a shearing force.

Further, in the case where the user extends the extendable portion 70 rearward after wearing the worn article U to which the main body portion 11 is fixed, it becomes difficult to visually recognize the extendable portion 70. Since the extendable portion 70 is arranged closer to the skin surface than the main body portion 11, even if it is difficult to visually recognize the extendable portion 70, the user can easily grip the extendable portion 70. As a result, the user can easily pull out the extendable portion 70. Further, when pulling out the extendable portion 70, it is possible to reduce the rubbing between the worn article U arranged on the non-skin surface side of the main body portion 11 and the extendable portion 70. Therefore, the user can easily pull out the extendable portion in a state where the non-extendable absorbent article (main body portion 11) is fixed to the worn article U.

In particular, in the case where the extendable portion 70 is extended after the user has attached the worn article U to which the main body portion 11 is fixed, a space is provided between the user's body CBL and the worn article U due to intergluteal cleft. Is formed (see FIG. 11A). In addition, the user inserts a hand into the worn article U to grip the extendable portion 70. Therefore, due to the insertion of the hand, the space between the user's body CBL and the worn article U increases. In addition, since worn items U such as shorts often have contractility so as to fit the user's skin, they can be used by keeping the inserted hand away from the user's body (back). It is also possible to secure a space between the person's body CBL and the worn article U. Therefore, even after the worn article U is attached, it is possible to secure a space in which the first portion 71 is turned over, and the user can easily pull out the extendable portion 70.

Further, as shown in FIGS. 10A to 10C, when the extendable portion 70 is extended, the position of the auxiliary folding portion SFL moves to the dorsal side as the user's hand is lifted to the dorsal side. That is, the position of the auxiliary fold portion SFL protruding from the worn article U toward the user's skin continues to exist near the position of the user's hand. Therefore, the position of the auxiliary folding portion SFL tends to exist at the position of the space caused by the insertion of the hand, so that it is difficult to be sandwiched between the worn article U and the skin. Therefore, the user is particularly likely to extend the extendable portion 70.

Further, the front-rear guidance portion 81L of the main body may be arranged behind the center ERc of the excretion port contact region ER in the front-rear direction L. That is, the bending guide portion 80 may be arranged in the main body portion 11 behind the center ERc of the excretion port contact region ER in the front-rear direction L. The portion posterior to the excretion opening contact area ER is a portion that easily faces the user's buttocks and / or perineum. Therefore, when the main body front-rear guiding portion 81L faces the buttocks, the main body front-rear guiding portion 81L makes it easier for the highly rigid first absorber 31 to bend along the intergluteal cleft. Specifically, the first absorber 31 bends in a V shape and easily enters the intergluteal cleft. Therefore, when the user pulls up the extendable portion 70, the center of the main body portion 11 in the width direction W approaches the user's body CBL (see FIG. 12B). As a result, the main body 11 can be easily fitted to the buttocks, and leakage of excrement can be suppressed. Further, when the main body front-rear guiding portion 81L faces the perineal portion, the main body front-rear guiding portion 81L similarly bends the first absorber 31 in a V shape in the perineal portion. As a result, the main body portion 11 can easily fit into the perineal portion, and leakage of excrement can be suppressed.

Further, the first absorber 31 may be joined to the skin side sheet 20 in order to prevent the first absorber 31 from twisting. Specifically, a portion adjacent to the bending guide portion 80 in the width direction may be joined to the skin side sheet 20. As a result, the first absorber 31 can be evenly fitted to the body without locally gathering.

Further, the extendable portion 70 faces the buttocks of the user at the time of extension. Therefore, the extending front-rear guiding portion 87L extending in the front-rear direction at the center of the width direction W makes it easier for the highly rigid first absorber 31 to bend along the intergluteal cleft. Specifically, as shown in FIG. 12C, the first absorber 31 bends in a V shape and easily enters the intergluteal cleft. Therefore, when the user pulls up the extendable portion 70, the center of the extendable portion 70 in the width direction W approaches the user's body CBL (see FIG. 12B). As a result, the extendable portion 70 can be easily fitted to the buttocks, and the leakage of excrement can be suppressed. Further, when the extendable portion 70 faces the perineal portion of the user at the time of extension, the extendable portion 70 easily fits in the perineal portion, and leakage of excrement can be suppressed.

Further, when the first portion 71 is bent by the first front-rear guiding portion 871L, in order for the first absorber 31 of the first portion 71 to move beyond the first front-rear guiding portion 871L, it depends on the degree of bending. It is necessary to change the direction of movement. Specifically, the first absorber 31 needs to move in a V shape. Therefore, the first absorber 31 becomes difficult to move beyond the first front-rear guiding portion 871L. As a result, it is possible to prevent the first absorber 31 of the first portion 71 from being twisted to one side in the width direction W. The absorption performance can be kept uniform in the width direction W.

Similarly, when the second portion 72 is bent by the second front-rear guide portion 872L, the first absorber 31 becomes difficult to move beyond the second front-rear guide portion 872L. As a result, it is possible to prevent the first absorber 31 of the second portion 72 from being twisted to one side in the width direction W. The absorption performance can be kept uniform in the width direction W.

Further, since the extendable portion 70 is arranged on the rear side of the main body portion 11, the user can extend the extendable portion 70 when the worn article U to which the main body portion 11 is fixed is passed through the leg. It is difficult to see 70. In particular, in the case where the user extends the extendable portion 70 after wearing the worn article U, it is difficult for the user to visually recognize the extendable portion 70. When the thickness of the bending guide portion 80 extending in the center of the width direction W is different from the thickness of the surroundings, the user can recognize the center of the width direction W by touch even if the extendable portion 70 cannot be visually recognized. can do. Since the user can easily recognize the portion to be pulled out, it is easy to shorten the attachment time of the absorbent article 10.

Further, since the distance from the waist opening on the back side of the worn article U to the vaginal opening which is the excretion port is longer than the distance from the waist opening on the ventral side of the worn article U to the vaginal opening, the user can use the main body 11 When the extendable portion 70 is extended after the worn article U fixed to the above is attached, it may be difficult to grip the extendable portion 70 from the back side. In the non-extended state, the length from the center ERc of the excretion port contact area ER in the anteroposterior direction L to the trailing edge of the extendable portion 70 is absorbable from the center ERc of the excretion port contact area L in the anteroposterior direction. If it is longer than the length to the front edge of the article 10, the user can easily grip the extendable portion 70.

Further, at least in the central portion in the width direction W, the absorber 30 in the main body portion 11 is continuously joined to the skin side sheet 20 from at least the front end of the main body front-rear guiding portion 81L to the rear end of the absorber 30 in the main body portion 11. You can. As a result, the absorber 30 approaching the user's body by the front-rear guide portion 81L of the main body can be made difficult to be twisted during wearing, and the absorbent body 30 is hard to be separated from the skin side sheet 20 during wearing. The adhesion of the 30 to the body can be maintained, and the leakage of the liquid from the skin side sheet 20 and the skin can be prevented.

Further, at least in the central portion (central region CR) in the width direction W, the absorber 30 may be continuously joined from the front end of the absorber 30 in the first portion 71 to the rear end of the absorber 30 in the first portion 71. As a result, when the extendable portion 70 is extended, the absorber 30 does not separate from the skin side sheet 20, so that the absorber 30 can be extended firmly to the end. In addition, since the absorber 30 in the first portion 71 can be made difficult to be twisted during wearing and the absorbent body 30 is hard to be separated from the skin side sheet 20 during wearing, the adhesiveness of the absorbent body 30 to the body is maintained. Can continue to do. In addition, it is possible to prevent leakage.

Further, at least in the central portion in the width direction W, it is continuously joined to the skin side sheet 20 from the front end of the absorber 30 in the second portion 72 to at least the rear end of the extension front-rear guidance portion 87L (second front-rear guidance portion 872L). May be done. Since the absorber 30 in the second portion 72 can be made hard to be twisted during wearing and the absorbent body 30 is hard to be separated from the skin side sheet 20 during wearing, the absorbent body 30 can be kept in close contact with the body. Can be done. In addition, it is possible to prevent leakage.

(4) Modification example The modification example will be described below. The same contents as those already described will be omitted as appropriate.

(4.1) Change example 1
The absorbent article 10 according to the first modification will be described with reference to FIGS. 13 and 14. FIG. 13 is a schematic plan view of the absorbent article according to Modification 1 as viewed from the skin surface side in the non-extended state. FIG. 14 is a schematic plan view of the absorbent article according to Modification 1 as viewed from the non-skin surface side in the non-extended state.

In the absorbent article 10 according to the first modification, the extendable portion 70 is arranged on the non-skin surface side of the main body portion 11 in the non-extended state. Therefore, the extendable portion 70 is a portion of the main body portion 11 that is folded toward the non-skin surface side.

The absorbent article 10 is folded so that the non-skin side sheet 25 of the main body portion 11 and the non-skin side sheet 25 of the first portion 71 face each other with the boundary folding portion BFL as a base point. The boundary fold portion BFL corresponds to a fold portion that is folded into a mountain fold when viewed from the skin surface side. Further, the absorbent article 10 is folded so that the skin-side sheet 20 of the first portion 71 and the skin-side sheet 20 of the second portion 72 face each other with the auxiliary folding portion SFL as a base point. The auxiliary fold SFL corresponds to a fold that is folded into a valley fold when viewed from the skin surface side. Therefore, the first portion 71 may be arranged on the non-skin surface side of the main body portion 11, and the second portion 72 may be arranged on the non-skin surface side of the first portion 71.

As shown in FIG. 13, in the overlapping region OR, even when the extendable portion 70 is not visible from the skin surface side T1, the absorbent article 10 is formed inside and outside the width direction W of the article outer edge 10E. Since the thickness of the portion changes, it is possible to give a sense of discomfort to the user and make it easier for the user to recognize the existence of the extendable portion 70.

In addition, since the outer edge 72E of the second portion 72 is arranged so as to be displaced inward in the width direction W from the outer edge 11E of the main body 11 with the boundary folding portion BFL as a boundary, the user can visually see it. It is easy to give a sense of discomfort. This makes it easier for the user to recognize the existence of the extendable portion 70.

(4.2) Change example 2
Next, the absorbent article 10 according to the second modification will be described with reference to FIG. FIG. 15 is a schematic plan view of the absorbent article 10 according to the second modification. FIG. 15A is a schematic plan view of the absorbent article according to Modification 2 as viewed from the skin surface side in the non-extended state. FIG. 15B is a schematic plan view of the absorbent article according to Modification 2 as viewed from the non-skin surface side in the non-extended state. FIG. 15C is a schematic plan view of the absorbent article according to Modification 2 as viewed from the non-skin surface side in the extended state.

In the absorbent article 10 according to the second modification, the extendable portion 70 is arranged on the rear side of the main body portion 11 and can be extended rearward.

The absorbent article 10 may have a wing 15 that is folded back on the non-skin surface side of the worn article U. In the state where the absorbent article 10 is packaged in the packaging sheet 100, the wing 15 may be folded inward in the width direction W by the folding portion extending in the front-rear direction L. The wing 15 may be a portion outside the folded portion in the width direction W.

The adhesive portion 50 may have a wing adhesive portion 55 provided on the wing 15. The wing 15 may be folded back to the non-skin surface side of the worn article U and then fixed to the worn article U via the wing adhesive portion 55.

As shown in FIG. 15A, in the non-extended state, the extendable portion 70 may be arranged behind the rear end 15R of the wing 15. The rear end 15R of the wing 15 may be arranged in front of the auxiliary folding portion SFL, which is the front end edge of the extendable portion 70.

As a result, the extendable portion 70 is easily arranged on the rear side of the user. Since the user can easily grip the extendable portion 70 from the rear side of the user while the worn article to which the absorbent article 10 is attached is passed through the leg, the extendable portion 70 can be easily extended. Become.

Further, in the non-extended state, the length L70 from the center Wic in the front-rear direction L of the wing 15 to the rearmost rear end edge 70R of the extendable portion 70 is absorbed from the center Wic in the front-rear direction L of the wing 15. The length to the frontmost front edge 10F of the sex article 10 may be longer than L11. The wing 15 is generally folded back toward the non-skin surface side of the worn article U near the vaginal opening. Therefore, in the non-extended state, the extendable portion 70 can be easily gripped by increasing the length L70 from the vicinity of the vaginal opening to the trailing end edge 70R of the extendable portion 70.

As shown in FIG. 15A, the outer edge 71E of the first portion 71 and the outer edge 72E of the second portion 72 may be the article outer edge 10E. The outer edge 11E of the main body 11 may be an overlapping outer edge OSE. Similar to the first modification, the thickness of the absorbent article 10 changes between the inside and the outside of the width direction W of the article outer edge 10E, which gives the user a sense of discomfort and allows the user to extend the extendable portion 70. It is possible to make it easier to recognize the existence.

Further, the outer edge 72E of the second portion 72 may be arranged so as to be offset from the outer edge 11E of the main body portion 11 to the outside in the width direction W with the boundary folding portion BFL as a boundary. This makes it easier for the user to feel a sense of discomfort. This makes it easier for the user to recognize the existence of the extendable portion 70.

(4.3) Change example 3
Next, the absorbent article 10 according to the third modification will be described with reference to FIG. FIG. 16 is a diagram for explaining the absorbent article 10 according to the third modification. FIG. 16A is a schematic plan view of the absorbent article according to Modification 3 as viewed from the skin surface side in the non-extended state. FIG. 16B is a schematic cross-sectional view taken along the line F16B-F16B of FIG. 16A.

As shown in FIG. 16, the absorbent article 10 may be diffracted once in the unfolded state. Therefore, the extendable portion 70 may have a first portion 71 which is a portion from the boundary folding portion BFL to the outer edge of the absorbent article 10 in the front-rear direction L. The extendable portion 70 may be composed of only the first portion 71 extending inward in the front-rear direction L from the boundary folding portion BFL. That is, in the unfolded state, the extendable portion 70 itself does not have to be folded.

The extendable portion 70 is located on the skin surface side of the main body portion 11. Therefore, the absorbent article 10 is folded so that the skin-side sheet 20 of the main body 11 and the skin-side sheet 20 of the extendable portion 70 (first portion 71) face each other with the boundary folding portion BFL as a base point. .. In the unfolded state, the extendable portion 70 is not sandwiched between the main body portion 11 and the packaging sheet 100 in the thickness direction T. As a result, the user does not have to grip the extendable portion 70 between the main body portion 11 and the worn article U, so that the extendable portion 70 can be easily gripped.

In the non-extended state, the extendable portion 70 does not extend to the outside of the front-rear direction L from the outer end edge (that is, the boundary folding portion BFL) of the main body portion 11 in the front-rear direction L, and thus is in the non-extended state. The length of the absorbent article 10 in the front-rear direction L can be shortened. Therefore, the user can easily fix the main body 11 to the worn article U.

As shown in FIGS. 16A and 16B, the extendable portion 70 may be provided with an extendable adhesive portion 52 on the non-skin side sheet 25. As a result, it is possible to prevent the extendable portion 70 from being displaced due to the daily movement of the user wearing the worn article U.

The extension adhesive portion 52 may be provided at a position where it does not overlap with the bending guide portion 80 provided in the extendable portion 70 in the thickness direction T. As a result, the bending of the absorber 30 caused by the bending guiding portion 80 is not hindered by the extendable portion 70.

As shown in FIG. 16A, in this modified example, the first portion 71 is arranged farthest from the main body portion 11 on one side of the thickness direction T in the plan view of the absorbent article 10 in the non-extended state. It is the extendable part 70. In the overlapping region OR, the outer edge 11E of the main body 11 may be the article outer edge 10E, and the outer edge 71E of the first portion 71 may be the overlapping outer edge OSE. Since the outer edge 71E of the first portion 71 is arranged inside the outer edge 11E of the main body 11 in the width direction W, the user can easily touch the overlapping outer edge OSE. As a result, it is possible to give the user a sense of discomfort and make it easier for the user to recognize the existence of the extendable portion 70. In addition, since the thickness of the absorbent article 10 changes between the inside and the outside of the width direction W of the article outer edge 10E, it gives a sense of discomfort to the user and makes the user recognize the existence of the extendable portion 70. It can be made easier.

Further, in the non-extended state, the extendable portion 70 is arranged on the skin surface side T1 of the main body portion 11, so that the user can visually recognize the overlapping outer edge OSE and use it. It is possible to make it easier for a person to recognize the existence of the extendable portion 70.

(4.4) Change example 4
Next, the absorbent article 10 according to the modified example 4 will be described with reference to FIG. FIG. 17 is a schematic plan view of the absorbent article 10 according to the fourth modification. FIG. 17A is a schematic plan view of the absorbent article according to the modified example 4 viewed from the skin surface side in the non-extended state. FIG. 17B is a schematic plan view of the absorbent article according to the modified example 4 as viewed from the non-skin surface side in the non-extended state. FIG. 17C is a schematic plan view of the absorbent article according to the modified example 4 as viewed from the non-skin surface side in the extended state.

In the absorbent article 10 according to the fifth modification, as shown in FIG. 17, the outer edge 71E of the first portion 71 may be the outer edge 10E of the article in the overlapping region OR, and the outer edge 11E and the first of the main body 11 Both of the outer edges 72E of the two portions 72 may be overlapping outer edge OSEs. Therefore, the first overlapping region OR1 and the third overlapping region OR3 may be adjacent to each other in the width direction W.
An extension adhesive portion 52 may be arranged in the first overlapping region OR1. A release sheet may face the extending adhesive portion 52. The user may peel off the release sheet to expose the extendable adhesive portion 52 before fixing the extendable portion 70. The outer portion (first overlapping region OR1) of the first portion 71 may function as a wing. Therefore, the outer portion of the first portion 71 may be folded back toward the non-skin surface side of the worn article U.
