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

A pants-type wearing article that provides effective buttocks covering having a front panel, a rear panel and a crotch panel connected to the front panel and the rear panel so as to cover a crotch region of the article wearer. The rear panel is formed with a rear waist covering portion having a dimension in the longitudinal direction substantially the same as a dimension of the front panel and a buttocks covering portion contiguously extending downward from the rear waist covering portion and adapted to cover at least partially the wearer's buttocks. The buttocks covering portion has buttock elastics extending in the transverse direction. The buttocks covering portion and the crotch panel are joined to each other in a zone defined between the gasket cuffs opposite to each other in the transverse direction and not joined to each other at portions in which the gasket cuffs are disposed.

A wearing article having a waist-opening that can be easily folded back along a fold line extending in a transverse direction without increasing the stiffness in the vicinity of the waist-opening. A diaper includes front and rear waist members and a crotch member. A liquid-absorbent structure of the crotch member is formed outboard of in a longitudinal direction of a core with front and rear flaps exclusively composed of an absorption surface wrapping sheet, a leakage-barrier sheet and a bottom surface wrapping sheet. The front and rear waist members include first regions overlapping the front and rear flaps, respectively, second regions lying adjacent to the associated first regions and third regions lying adjacent to the associated second regions. The front and rear waist members are provided with the first, second and third waist elastics attached between respective inner and outer sheets in the first, second and third regions, respectively. A tensile stress of the first regions and the third regions is adjusted to be lower than that of the second regions.

Wearing article

A wearing article configured to smooth out wrinkles that tend to be created in front and rear waist regions. A diaper includes front and rear waist members connected to an intermediary crotch. The front and rear waist members extend from waist ends toward the side of a crotch region and respectively include first regions overlapping front and rear end flaps of the absorbent structure and second regions adjacent the respective first regions. In the front and rear waist members, the first regions and the second regions are provided with first and second waist elastic members sandwiched between the respective top- and backsheets. The respective second regions are formed with inelastic zones overlapping the core and elastic regions lying on both sides of the inelastic regions in the transverse direction. The tightening force of the first regions are lower than the tightening force of the respective second regions.
