A stretchable absorbent article, such as a diaper, a sanitary product or other absorbent member, comprises a liquid permeable layer, and a liquid impermeable elastic layer stretchably secured to the liquid permeable layer at discrete regions so as to form regions of nonsecurement between the discrete regions of securement. The liquid permeable layer forms corrugations at respective regions of nonsecurement for respectively defining channels between the liquid permeable layer and the liquid impermeable elastic layer. Absorbent material is disposed in selected ones of the channels.

DETAILED DESCRIPTION The present invention provides a stretchable absorbent article for fitting about and enclosing a waist portion of a wearer.
The article comprises a main body comprising an elastic composite sheet.
The elastic composite sheet comprises an elastic sheet and a non-woven material in the form of non-woven fabric secured to at least one surface of the elastic sheet.
The non-woven fabric is secured to the elastic sheet continuously in a first direction and intermittently in a second direction perpendicular to the first direction to define therebetween a plurality of parallel channels extending in the first direction.
The elastic composite sheet may be dual-layered (i.
e.
, doubled) in the region of at least one of a front waist portion, a rear waist portion, a crotch region, and a leg-hole surrounding portion in the main body.
The present invention further provides a stretchable absorbent article which comprises a liquid permeable layer, and a liquid impermeable elastic layer stretchably secured to the liquid permeable layer by a plurality of laterally spaced, parallel lines of securement so as to form laterally spaced, parallel regions of nonsecurement.
The liquid permeable layer forms corrugations at the respective regions of nonsecurement for defining a plurality of parallel channels between the liquid permeable layer and the liquid impermeable elstic layer.
Absorbent material is disposed in a selected location of the absorbent article.
In another aspect of the present invention, there is provided a stretchable absorbent member which comprises a liquid permeable layer, and a liquid impermeable elastic layer stretchably secured to the liquid permeable layer at discrete regions so as to form regions of nonsecurement between the discrete regions of securement.
The liquid permeable layer forms corrugations at the respective regions of nonsecurement for defining respective channels between the liquid permeable layer and the liquid impermeable elastic layer.
Absorbent material is disposed in selected ones of the channels
