Abstract
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.
Claims26
A stretchable absorbent article for fitting about the waist of a wearer, said article comprising:
- a main body comprising an elastic composite sheet,
- said elastic composite sheet comprising an elastic sheet and a non-woven fabric layer secured to at least one surface of said elastic sheet,
- said non-woven fabric layer being secured to said elastic sheet continuously in a first direction and intermittently in a second direction perpendicular to said first direction to define therebetween a plurality of parallel channels extending in said first direction,
- said stretchable absorbent article including juxtaposed dual layers of said elastic composite sheet in the region of at least one of a front waist portion, a rear waist portion, a crotch portion, and portions surrounding leg holes of said main body, each of said elastic composite sheets comprising one of said elastic sheets and one of said non-woven fabric layers.
An absorbent article having a stretchable region, said stretchable region including a liquid permeable layer, a liquid impermeable elastic layer stretchably secured to said liquid permeable layer at discrete regions to form regions of nonsecurement between adjacent ones of said discrete regions of securement, said liquid permeable layer forming corrugations at the respective regions of nonsecurement for defining respective channels between said liquid permeable layer and said liquid impermeable layer, and absorbent material disposed in selected ones of said channels so that said liquid impermeable plastic layer is stretchable at an area of said selected ones of said channels in a direction generally transverse to said selected ones of said channels.
An absorbent article comprising:
- a liquid permeable topsheet;
- a liquid impermeable backsheet having an elastic area, said elastic area being stretchably secured to said liquid permeable topsheet by a plurality of spaced, parallel lines of securement so as to form regions of nonsecurement, said liquid permeable layer respectively forming corrugations at said regions of nonsecurement for defining a plurality of channels between said liquid permeable topsheet and said liquid impermeable backsheet;
- and
- absorbent material disposed in said channels in a selected location of said absorbent article, said elastic area of said liquid impermeable backsheet being stretchable at said selected location in a direction generally transverse to said channels.
A stretchable absorbent member, comprising:
- a liquid permeable layer;
- a liquid impermeable elastic layer stretchably secured to said liquid permeable layer at discrete regions so as to form regions of nonsecurement between said discrete regions of securement, said liquid permeable layer forming corrugations at said respective regions of nonsecurement for defining respective channels between said liquid permeable layer and said liquid impermeable elastic layer;
- and
- absorbent material disposed in selected ones of said channels, said liquid impermeable elastic layer being stretchable at an area of said selected ones of said channels in a direction generally transverse to said channels.
A stretchable absorbent member, comprising:
- a liquid permeable layer;
- a liquid impermeable elastic layer stretchably secured to said liquid permeable layer by a plurality of laterally spaced, parallel lines of securement so as to form regions of nonsecurement, said liquid permeable layer respectively forming corrugations at said regions of nonsecurement for defining a plurality of parallel channels between said liquid permeable layer and said liquid impermeable elastic layer;
- and
- absorbent material disposed in selected ones of said channels, said liquid impermeable elastic layer being stretchable at an area of said selected ones of said channels in a direction generally transverse to said channels.
