Claim 1
Independent Claim
239 words
A disposable absorbent pad such as a baby diaper or adult incontinent pad comprising: a backsheet having a width and a length, a multi-ply topsheet, a absorbent core, having lateral edges and end edges, located between said backsheet and said topsheet, the backsheet and the topsheet being secured together around the lateral edges and end edges of said core to hold said core therebetween, said multi-ply topsheet including a first ply having a width equal to the width of the backsheet and further including a second ply which overlies said first ply, said second ply having lateral edges defining a width narrower than the width of said first ply, said second ply being non-removably secured on top of said first ply along a pair of fastening lines spaced inwardly from the lateral edges of the core, said second ply having first elastic members secured under tension to its lateral edges, said first elastic members having ends, said lateral edges of said second ply being pulled upwardly and away from the first ply by said first elastic members such that said lateral edges of said second ply are located between said first elastic members and said fastening lines and are substantially perpendicular to said first ply, the ends of said first elastic members being unsecured to the first ply, said first ply and said second ply being unsecured to each other between the fastening lines to provide a gap therebetween.
Claim 2
Dependent Claim
239 words
A disposable absorbent pad such as a baby diaper or adult incontinent pad comprising: a backsheet having a width and a length, a multi-ply topsheet, a absorbent core, having lateral edges and end edges, located between said backsheet and said topsheet, the backsheet and the topsheet being secured together around the lateral edges and end edges of said core to hold said core therebetween, said multi-ply topsheet including a first ply having a width equal to the width of the backsheet and further including a second ply which overlies said first ply, said second ply having lateral edges defining a width narrower than the width of said first ply, said second ply being non-removably secured on top of said first ply along a pair of fastening lines spaced inwardly from the lateral edges of the core, said second ply having first elastic members secured under tension to its lateral edges, said first elastic members having ends, said lateral edges of said second ply being pulled upwardly and away from the first ply by said first elastic members such that said lateral edges of said second ply are located between said first elastic members and said fastening lines and are substantially perpendicular to said first ply, the ends of said first elastic members being unsecured to the first ply, said first ply and said second ply being unsecured to each other between the fastening lines to provide a gap therebetween.
Claim 3
Dependent Claim
34 words
A disposable absorbent pad of claim 1 wherein the lateral edges of said second ply include a portion folded back upon itself to create a tunnel in which said first elastic members are disposed.
Claim 4
Dependent Claim
52 words
A disposable absorbent pad of claim 2 wherein the second ply is formed of a fluid-pervious material between the lines wherein said second ply is secured to said first ply, said second ply being treated to render it impervious to both liquids and gases between the fastening lines and the lateral edges.
Claim 5
Dependent Claim
19 words
The pad of claim 3 wherein the second ply is treated with a thin coating of hot melt material.
Claim 6
Dependent Claim
41 words
A disposable absorbent pad of claim 4 wherein means for securing the backsheet and the topsheet to each other means for providing the fastening lines, and means for rendering the lateral edge of the second ply impervious, is a degradable adhesive.
Claim 7
Dependent Claim
16 words
The pad of claim 3 wherein the second ply is treated with a thin plastic film.
Claim 8
Dependent Claim
12 words
The pad of claim 6 wherein the thin plastic film is polyethylene.
Claim 9
Dependent Claim
23 words
A disposable absorbent pad of claim 2 wherein the portion of said lateral edge which is folded back upon itself is folded outwardly.
Claim 10
Dependent Claim
23 words
A disposable absorbent pad of claim 2 wherein the portion of said lateral edge which is folded back upon itself is folded inwardly.
Claim 11
Dependent Claim
40 words
A disposable absorbent pad of claim 1 wherein the width of the first ply plus the width of the second ply of the multi-ply top sheet is less than twice the width of the first ply of said multi-ply topsheet.
Claim 12
Dependent Claim
31 words
A disposable absorbent pad of claim 1 including second elastic members, said second elastic members secured under tension to said backsheet and topsheet outwardly of the lateral edges of said core.
Claim 13
Dependent Claim
51 words
A disposable absorbent pad of claim 11 wherein pulling upward of the lateral edges of said second ply by said first elastic members creates a tension in the second elastic members which is greater than the tension in the first elastic members secured along the lateral edges of the second ply.
Claim 14
Dependent Claim
24 words
A disposable absorbent pad of claim 1 wherein the first ply is a laminate which is made of a plurality of different non-woven materials.
Claim 15
Dependent Claim
28 words
