Abstract

The present invention is directed to a disposable absorbent article. The disposable absorbent article has a longitudinal centerline, a lateral centerline, an outer surface and an inner surface. The absorbent article is folded before use along the lateral direction. The disposable absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed therebetween, and an elasticized outer leg cuff. The elasticized outer leg cuff is disposed adjacent to a longitudinal side edge of the absorbent article. The elasticized outer leg cuff has a base and a gasket cuff supported by the base at a joint of the base to the gasket cuff. The gasket cuff is provided with elasticity and has a top gasket cuff surface, an inner cuff extending laterally inwardly from the joint and an outer cuff extending laterally outwardly from the joint. Before use of the absorbent article, the elasticized outer leg cuff is folded laterally inwardly onto the inner surface of the absorbent article such that the top gasket cuff surface faces upwardly.

First claim

What is claimed is:

1 . A disposable absorbent article having a longitudinal centerline, a lateral centerline, an outer surface and an inner surface, a front waist region, a back waist region and a crotch region disposed between said front waist region and said back waist region, said disposable absorbent article comprising:
a liquid pervious topsheet having first and second longitudinal side edges; a liquid impervious backsheet comprising a liquid impervious backsheet film and an outer nonwoven covering, the liquid impervious backsheet film having first and second longitudinal side edges; an absorbent core disposed between said liquid pervious topsheet and said liquid impervious backsheet film; a first barrier leg cuff comprising a lateral outer portion and an elastic strand, wherein said elastic strand of said first barrier leg cuff is disposed inboard of said first longitudinal side edge of said liquid impervious backsheet film; a first elasticized outer leg cuff comprising a plurality of elastic strands that extend longitudinally in said crotch region, wherein at least a portion of said first elasticized outer leg cuff extends outboard of said first longitudinal side edge of said liquid impervious backsheet film; a second barrier leg cuff comprising a lateral outer portion and an elastic strand, wherein said elastic strand of said second barrier leg cuff is disposed inboard of said second longitudinal side edge of said liquid impervious backsheet film; and a second elasticized outer leg cuff comprising a plurality of elastic strands that extend longitudinally in said crotch region, wherein at least a portion of said second elasticized outer leg cuff extends outboard of said second longitudinal side edge of said liquid impervious backsheet film; wherein the lateral outer portion of the first barrier leg cuff extends laterally outward beyond the first longitudinal side edge of the liquid pervious topsheet and the first longitudinal edge of the liquid impervious backsheet film; and wherein the lateral outer portion of the second barrier leg cuff extends laterally outward beyond the second longitudinal side edge of the liquid pervious topsheet and the second longitudinal edge of the liquid impervious backsheet film.

2 . The disposable absorbent article of claim 1 wherein said plurality of elastic strands of said first elasticized outer leg cuff are disposed outboard said first longitudinal side edge of said liquid impervious backsheet film and said plurality of elastic strands of said second elasticized outer leg cuff are disposed outboard said second longitudinal side edge of said liquid impervious backsheet film.

3 . The disposable absorbent article of claim 1 , wherein said liquid impervious backsheet film is a microporous film.

4 . The disposable absorbent article of claim 1 , wherein said absorbent core comprises first and second longitudinal side edges, wherein a first portion of said disposable absorbent article is folded along a first longitudinal folding line such that said first longitudinal side edge of said liquid impervious backsheet film is disposed inboard said first longitudinal side edge of said absorbent core, and wherein a second portion of said disposable absorbent article is folded along a second longitudinal folding line such that said second longitudinal side edge of said liquid impervious backsheet film is disposed inboard said second longitudinal side edge of said absorbent core.

5 . The disposable absorbent article of claim 1 , further comprising first and second ear panels disposed at said back waist region of said disposable absorbent article, wherein said first ear panel comprises a closure member and wherein said second ear panel comprises a closure member.

6 . The disposable absorbent article of claim 5 , wherein each of said first and second ear panels comprises inner and outer side edges, wherein said inner edge of said first ear panel is disposed between a first longitudinal folding line and a longitudinal centerline and wherein said inner edge of said second ear panel is disposed between a second longitudinal folding line and a longitudinal centerline.

7 . The disposable absorbent article of claim 6 , wherein said outer side edge of said first ear panel is disposed between said second longitudinal folding line and said longitudinal centerline and wherein said outer side edge of said second ear panel is disposed between said first longitudinal folding line and said longitudinal centerline.

8 . The disposable absorbent article of claim 5 , wherein said disposable absorbent article is folded along a lateral folding line such that said first and second ear panels are disposed between said front waist region and said back waist region.

9 . The disposable absorbent article of claim 1 , wherein said absorbent core comprises first and second longitudinal side edges, wherein a first portion of said disposable absorbent article is folded along a first longitudinal folding line such that said first longitudinal side edge of said absorbent core is disposed inboard said first longitudinal folding line, and wherein a second portion of said disposable absorbent article is folded along a second longitudinal folding line such that said second longitudinal side edge of said absorbent core is disposed inboard said second longitudinal folding line.

10 . The disposable absorbent article of claim 1 , further comprising an elastic waist feature disposed in at least one of said front and back waist regions.

11 . The disposable absorbent article of claim 1 , wherein said first barrier leg cuff and said first elasticized outer leg cuff are formed by a first layer of material that extends continuously between said first barrier leg cuff and said first elasticized outer leg cuff and wherein said second barrier leg cuff and said second elasticized outer leg cuff are formed by a second layer of material that extends continuously between said second barrier leg cuff and said second elasticized outer leg cuff

12 . The disposable absorbent article of claim 11 , wherein a first portion of said liquid pervious topsheet is joined to said liquid impervious backsheet film and to said first layer of material and wherein a second portion of said liquid pervious topsheet is joined to said liquid impervious backsheet film and to said second layer of material.

13 . The disposable absorbent article of claim 11 , wherein a first side portion of said liquid pervious topsheet is disposed between said liquid impervious backsheet film and said first layer of material and wherein a second side portion of said liquid pervious topsheet is disposed between said liquid impervious backsheet film and said second layer of material.

14 . The disposable absorbent article of claim 11 , wherein said plurality of elastic strands of said first elasticized outer leg cuff are disposed between a first portion and a second portion of said first layer of material and wherein said plurality of elastic strands of said second elasticized outer leg cuff are disposed between a first portion and a second portion of said second layer of material.

15 . The disposable absorbent article of claim 11 , wherein a portion of said first layer of material is joined directly to an inner surface of said liquid impervious backsheet film, and wherein a portion of said second layer of material is joined directly to an inner surface of said liquid impervious backsheet film.

16 . The disposable absorbent article of claim 11 , wherein said first layer of material and said second layer of material comprise a nonwoven material, wher
