Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 78 words
A garment comprising a body engaging area said body engaging area comprising an elastomeric laminate comprising at least one discrete elastomeric layer and at least two discrete continuous skin layers at least one of which is a microtextured permanently deformed polymeric layer wherein the materials forming the elastomeric layer and the materials forming the polymeric layer are selected such that said at least one elastomeric layer and said at least one microtextured skin layer are in continuous contact.
Claim 2
Dependent Claim 78 words
A garment comprising a body engaging area said body engaging area comprising an elastomeric laminate comprising at least one discrete elastomeric layer and at least two discrete continuous skin layers at least one of which is a microtextured permanently deformed polymeric layer wherein the materials forming the elastomeric layer and the materials forming the polymeric layer are selected such that said at least one elastomeric layer and said at least one microtextured skin layer are in continuous contact.
Claim 3
Dependent Claim 18 words
The garment of claim 1 comprising a diaper wherein said body engaging area is a waist engaging area.
Claim 4
Dependent Claim 18 words
The garment of claim 1 comprising a diaper wherein said body engaging area is a leg engaging area.
Claim 5
Dependent Claim 18 words
The garment of claim 1 comprising a diaper wherein said body engaging area is a hip engaging area.
Claim 6
Dependent Claim 28 words
The garment of claim 1 wherein: (a) said elastomeric laminate is a film and (b) each layer has a substantially constant thickness across the width of said film.
Claim 7
Dependent Claim 32 words
The garment of claim 1 wherein the width of said laminate will decrease by less than 20% when restretched to the extent of permanent deformation of the previously deformed microtextured skin layer.
Claim 8
Dependent Claim 24 words
