<Embodiment>
In the present embodiment, the tape-type disposable diaper (an example of the "absorbent article" in the present application, hereinafter simply referred to as "diaper") faces the front body and the back, which are arranged to face the abdomen of the wearer. The direction connecting the back body to be arranged is the longitudinal direction. An inseam placed in the wearer's inseam (opposed to the crotch) between these front bodies (one side in the longitudinal direction) and the back body (other side in the longitudinal direction) (center in the longitudinal direction). The part is located. In addition, when the diaper is worn on the wearer (hereinafter abbreviated as "wearing state"), the side facing the wearer's skin (inside when worn) is the skin side, and the opposite side of the skin side. (Outside when attached) is the non-skin side. Further, the direction connecting the skin surface side and the non-skin surface side is the thickness direction, and the direction orthogonal to both the longitudinal direction and the thickness direction is the width direction. In addition, viewing from the thickness direction is defined as a plan view.

FIG. 1 is a perspective view of a diaper according to the present embodiment. The diaper 1 has an inseam area 1B, which is a part corresponding to the inseam covering the wearer's genital area in the worn state, and a front body area 1F, which is located on the front side of the inseam area 1B and corresponds to the wearer's front body. It is located behind the inseam region 1B and has a back body region 1R which is a portion corresponding to the back body of the wearer. Front patches 2F (front patch 2F) provided on the non-wearer side of the front body area 1F on the left and right edges of the back body area 1R.
Tapes 2L and 2R that can be attached to (an example of the "front sheet") are provided. The diaper 1 is worn when the tapes 2L and 2R are attached to the front patch 2F with the front body area 1F arranged on the ventral side of the wearer and the back body area 1R arranged on the back side of the wearer. It is fixed to the wearer's body in a state surrounding the person's abdominal circumference and thigh. Since the diaper 1 is fixed to the wearer's body in such a form, the wearer can walk while wearing the diaper 1.

In the diaper 1, an absorber capable of absorbing and holding the liquid is mainly arranged around the inseam region 1B. Further, in the diaper 1, in order to prevent the formation of a gap that serves as a liquid outflow route between the diaper 1 and the wearer's skin, the portion surrounding the wearer's leg circumference (thigh) is formed. Leg gathers 3AL and 3AR are provided, three-dimensional gathers 3BL and 3BR are provided inside the width direction of the diaper 1 with respect to the leg gathers 3AL and 3AR, and waist gathers 3R are provided at a portion surrounding the wearer's abdominal circumference. The leg gathers 3AL, 3AR, three-dimensional gathers 3BL, 3BR and waist gather 3R adhere to the wearer's skin due to the elastic force of the rubber thread. Therefore, the liquid discharged from the pubic area of the wearer is absorbed by the absorber of the diaper 1 without leaking from the diaper 1.

FIG. 2 is an exploded perspective view of the diaper 1. Further, FIG. 3 is a cross-sectional view of the diaper 1 in the non-wearing state when the center in the longitudinal direction is cut along the width direction. FIG. 4 is a plan view of the stretched diaper 1 as viewed from the skin surface side. In FIG. 4 and later, the alternate long and short dash line C1 is a center line representing the center of the diaper 1 in the width direction. The diaper 1 has a cover sheet 4 (an example of an "exterior sheet") that forms an outer surface when worn. The cover sheet 4 is a sheet-like member having a substantially rectangular appearance with 4KL and 4KR constricted in a portion corresponding to a long side, and forms an exterior surface of the diaper 1. The constrictions 4KL and 4KR are provided at a portion where the wearer's thigh is located (leg circumference regions 10L and 10R shown in FIG. 4). The cover sheet 4 is provided for reinforcing the back sheet 5 and improving the feel, which will be described later. For example, in order to suppress leakage of excrement, a non-woven fabric made of a liquid-impermeable thermoplastic resin is used as the material thereof. be able to. Examples of the liquid-impermeable thermoplastic resin include polyethylene (PE) and polypropylene (PP). The cover sheet 4 is not limited to a single-layer structure, and may have a multi-layer structure having an inner cover sheet and an outer cover sheet.

The diaper 1 has a back sheet 5, an absorber 6C, and a top sheet 7 that are sequentially laminated on the wearer-side surface of the cover sheet 4. The back sheet 5, the absorber 6C, and the top sheet 7 are all sheet-like members having a substantially rectangular appearance, and are laminated in order on the cover sheet 4 in a state where the longitudinal direction coincides with the longitudinal direction of the cover sheet 4. There is. Like the cover sheet 4, the back sheet 5 is a sheet formed of a liquid-impermeable thermoplastic resin as a material in order to suppress leakage of excrement. The back seat 5 is preferably made of a material having moisture permeability in order to suppress stuffiness in the wearing state. Further, the top sheet 7 is a sheet-like member arranged on the skin surface side of the wearer so as to cover the water absorption surface of the absorber 6C. The top sheet 7 has liquid permeability in a part or all of it. Therefore, in the state where the diaper 1 is worn, the liquid excreted from the wearer enters the absorber 6C through the top sheet 7 which can come into contact with the wearer's skin, and is absorbed there. For example, a woven fabric, a non-woven fabric, or a porous film can be used as a material for the top sheet 7. The top sheet 7 may have hydrophilicity. Further, the absorber 6C is arranged including the inseam region 1B.

The back sheet 5, the absorber 6C, and the top sheet 7 all extend from the front body region 1F to the back body region 1R. Therefore, when the wearer's pubic area is covered with the cover sheet 4 in which the back sheet 5, the absorber 6C, and the top sheet 7 are laminated, both ends of the back sheet 5, the absorber 6C, and the top sheet 7 in each longitudinal direction are displayed. It will be located on the ventral and dorsal sides of the wearer. That is, the genital area of the wearer is covered with the absorber 6C from the ventral side to the dorsal side of the wearer. Therefore, regardless of whether the wearer discharges the liquid to the outside of the body in either the abdomen-down posture or the back-down posture, the discharged liquid contacts the absorber 6C via the top sheet 7. Will be done.

Further, the diaper 1 is provided so that the thread rubbers 4SL and 4SR for forming the leg gathers 3AL and 3AR described above expand and contract in the longitudinal direction of the diaper 1 between the cover sheet 4 and the back sheet 5. The thread rubbers 4SL and 4SR are provided in an appropriate number (three in the present embodiment) determined according to the elastic force (shrinkage force) required for the design of the diaper 1. As shown in FIG. 4, the leg gathers 3AL and 3AR are arranged including the leg circumference regions 10L and 10R, which are the portions where the wearer's thighs are located in the widthwise both end diapers 1 of the inseam region 1B. Has been done. The leg circumference regions 10L and 10R are arranged at both side ends in the width direction of the inseam region 1B. Further, the arrangement areas of the thread rubbers 4SL and 4SR are the leg gathers 3AL and 3AR.

Further, the diaper 1 has elongated strip-shaped side seats 8L and 8R. The side sheets 8L and 8R are liquid-impermeable sheets provided on the long side portion of the top sheet 7. Similar to the cover sheet 4, the side seats 8L and 8R are provided with 8KL and 8KR constricted in a portion where the wearer's thigh is located (leg circumference area 10L and 10R shown in FIG. 4). The side sheets 8L and 8R are woven with thread rubbers 8EL and 8ER for forming the three-dimensional gathers 3BL and 3BR along the longitudinal direction. When the diaper 1 is in the mounted state, that is, when the diaper 1 is in the U-shaped side view, the side sheets 8L and 8R are pulled in the longitudinal direction by the contraction force of the rubber threads 8EL and 8ER and rise from the top sheet 7. , The three-dimensional gathers 3BL and 3BR that prevent the outflow of liquid.

In the cover sheet 4, the thread rubber 4C that prevents a gap from being formed between the diaper 1 and the wearer's abdominal circumference is inside the width direction of the diaper 1 with respect to the thread rubbers 4SL and 4SR in the longitudinal direction of the diaper 1. It is provided along. The thread rubber 4C is provided in an appropriate number (three in the present embodiment) determined according to the elastic force (shrinkage force) required for the design of the diaper 1.

Further, the thread rubber 9ER for forming the waist gather 3R described above is provided between the back sheet 5 and the top sheet 7 at a position further back than the end portion of the absorber 6C. The rubber thread 9ER is provided between the back sheet 5 and the top sheet 7 in a direction in which the longitudinal direction, which is the expansion and contraction direction, is the left-right direction of the diaper 1. Therefore, when the tapes 2L and 2R provided on the left and right sides of the rubber thread 9ER are attached to the front patch 2F on the ventral side of the wearer, the rubber thread 9ER exerts a contraction force to give the diaper 1 to the wearer. It is brought into close contact to prevent a gap from being formed between the diaper 1 and the wearer's abdominal circumference.

The absorber 6C contains water in the gaps between short fibers of cellulose-based fibers such as pulp fibers, rayon fibers, or cotton fibers, and short fibers obtained by hydrophilizing synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate. It has a structure in which granular absorbent resins such as SAP (Highly Absorbent Polymer), which is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining fibers, are retained. Therefore, in the absorber 6C, the volume fluctuation of the absorbent resin before and after absorbing the liquid is basically performed in the short fibers that hold the absorbent resin in the gap. Therefore, when the entire absorber 6C is viewed from a bird's-eye view, it can be said that the expansion coefficient of the thickness of the absorber 6C that has absorbed the liquid is not as large as the expansion coefficient of the absorbent resin itself.

The SAP particles of the present embodiment refer to particles of a resin composition containing SAP. The term "resin composition containing SAP" as used herein refers to both a composition consisting of SAP alone and a composition containing SAP as a main component and containing other substances to the extent that it does not adversely affect water absorption. It is a concept that includes. Examples of the "other substance" include additives (surface modifiers added for the purpose of hydrophobizing the particle surface), unreacted monomers remaining during the synthesis of SAP, and the like.

Next, the folded state of the diaper 1 according to the present embodiment will be described with reference to FIGS. 4 and 5. As shown in FIG. 4, the diaper 1 according to the present embodiment is arranged in the back body region 1R, and has a pair of side flap portions 11L, 11R extending outward in the width direction of the diaper 1 from the absorber 6C.
