An absorbent article includes: front waistline region; rear waistline region; crotch region disposed between front waistline region and rear waistline region; absorbent body that straddles crotch region, front waistline region, and rear waistline region; front exterior body disposed in front waistline region on non-skin surface side of absorbent body. Absorbent body includes absorbent core and front end part extending toward front side from absorbent core, a liquid-impermeable sheet and a liquid-permeable body sheet overlapping liquid-impermeable sheet in thickness direction are disposed at the front end part of absorbent body. Absorbent article includes: sheet non-bonding region where liquid-impermeable sheet and body sheet are not bonded; and body non-bonding region where absorbent body and front exterior body are not bonded. Front end part includes duplicating region where sheet non-bonding region and body non-bonding region overlap to each other.

Absorbent article including absorbent body and front exterior body disposed in front waistline region on non-skin surface side of absorbent body

In a disposable wearing article, a first waist region is elasticized and formed of an inner sheet and an outer sheet. The non-skin-facing side of the outer sheet is formed substantially over its entire area with a plurality of thermocompression-bonded spots regularly and intermittently arranged at predetermined intervals. The outer sheet has non-thermocompressed regions surrounded by a plurality of thermocompression-bonded spots. A fibrous layer lying at least on the outer surface of said outer sheet is formed of thermal adhesive crimped fibers which are bonded together by thermocompression-bonding treatment in the thermocompression-bonded spots. The outer sheet and the inner sheet are bonded to each other by adhesive applied on at least one of respective opposite surfaces thereof so that the crimped fibers in the non-thermocompressed regions may protrude outward in a thickness direction of the outer sheet as the inner sheet contracts in the direction of the transverse axis Q.

Disposable wearing article

A disposable wearing article includes a front side edges lying in a front waist region, rear side edges lying in a rear waist region and crotch side edges lying in a crotch region. A chassis of the diaper includes a first backsheet forming the front waist region and a part of the crotch region and a second backsheet forming the rear waist region and a part of the crotch region. The front and rear waist regions are provided with first front and rear waist elastic yarns or threads and front and rear region elastic sheets, and the crotch region is provided along the crotch side edges with front and rear leg elastic elements. Ends of front leg elastic elements on one side overlap the front side edges. Ends of the rear leg elastic elements on one side overlap the rear side edges.

The present invention provides a disposable wearing article adapted to inhibit sweating and an uncomfortable stuffiness. Front and rear waist regions of a disposable wearing article have inner surfaces thereof at least partially formed of elastic sheets. The elastic sheets are made of a mixture of elastic fibers and inelastic fibers and formed with ridges and grooves. The elastic sheets have a thickness in the ridges repetitively reduced and restored as the elastic sheets repeat elastic stretch and contraction in the waist circumferential direction.
