TECHNICAL FIELD The present invention relates to a pants-type disposable wearing article that absorbs and retains excrement.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 9-75390 discloses that a crotch region is located between front and rear waist regions that face each other, and the waist side portions of these waist regions are connected to each other to form a waist opening and a pair of legs. Disclosed is a pants-type disposable wearing article composed of pants defining a peripheral opening and a liquid-absorbent inner panel attached to the inside of the pants and extending from the crotch region toward the front and rear waist regions. .

The front and rear waist regions of the pants are formed of two fibrous nonwoven fabrics facing each other and a plastic film interposed between the nonwoven fabrics. The crotch region of the pants is formed of two fibrous nonwoven fabrics facing each other and a stretchable plastic film interposed between the nonwoven fabrics. In the front and rear waist regions of the underpants, a plurality of waist elastic members extending in the waist direction are attached in a stretched state. The waist elastic members are arranged longitudinally in the longitudinal direction between the waist opening and the leg openings by a predetermined distance.
Suspension pieces that extend from the ends of the waist opening to the crotch region are attached to the front and rear waist regions of the pants. In the underpants, the front waist region and the back waist region overlap with the back waist region in the shape of a palm, and a large number of heat fusion lines are formed in the vicinity of the side edges of the waist region intermittently in the longitudinal direction. It is fixed via a wire.

The inner panel has a substantially rectangular shape that is long in the vertical direction, and includes a liquid-permeable top sheet located on the skin contact side, a liquid-impermeable back sheet located on the skin non-contact side, and front and back sheets. It is formed of a liquid-absorbent core interposed therebetween. The panel is detachably attached to the suspension piece of the pants at the longitudinal ends located in the front and rear waist regions of the pants.

In this wearing article, the crotch region of the pants can be expanded and contracted in the vertical direction, and when it is worn, the panel is brought into close contact with the wearer's crotch region due to the vertically extending crotch region of the pants.

[0006]

In the wearing article disclosed in the above publication, even when the inner panel can be brought into close contact with the crotch of the wearer when the article is worn, the wearing of the pants stretched in the longitudinal direction is prevented. The crotch region may act to slide the front and back waist regions of the pants from the wearer's torso due to the contracting force, and as a result, the panel may be separated from the wearer's crotch. In addition, in this wearing article, even if the elastic member for the girth extending right above the crotch region in the girth direction acts to bring the panel into close contact with the wearer's torso by the contracting force, the longitudinal end portion of the panel Can only be brought into close contact with the wearer's torso portion, and the longitudinal center portion of the panel cannot be brought into close contact with the wearer's crotch portion.

An object of the present invention is to provide a pants-type disposable in which the longitudinal end portion and the longitudinal center portion of the inner panel can be brought into close contact with the wearer without lowering the worn article from the trunk of the wearer. To provide a worn article.
