Absorbent article with unitary elastomeric waistband with multiple extension zones
First Claim
1. An absorbent article, comprising:
- a chassis having a front waist region, a back waist region, and a crotch region extending between said front and back waist regions;
an outer cover member and a bodyside liner extending longitudinally between said front and back waist regions;
an absorbent body structure sandwiched between said outer cover member and said bodyside liner;
a unitary elastomeric structure attached to at least one of said front waist region or said back waist region, said elastomeric structure extending completely across said respective waist region and extending beyond lateral sides of said chassis so as to form elastomeric attachment tabs,said elastomeric structure having a predetermined first modulus of elasticity such that when attached to said waist region, a resulting elastomeric waistband portion is defined having an overall second modulus of elasticity that is less than said first modulus of elasticity of said attachment tabs.

Abstract
An absorbent article, such as a disposable diaper, includes a chassis having a front waist region, a back waist region, and a crotch region extending between the front and back waist regions. An outer cover member and a bodyside liner extend longitudinally between the front and back waist regions. An absorbent body structure is sandwiched between the outer cover member and the bodyside liner. A unitary elastomeric structure is attached to at least one of the front and back waist regions, the elastomeric structure extending completely across the respective waist region and extending beyond lateral sides of the chassis so as to form elastomeric attachment tabs. The elastomeric structure having a predetermined first modulus of elasticity such that when attached to said waist region, a resulting elastomeric waistband portion is defined having an overall second modulus of elasticity that is less than the first modulus of elasticity of the attachment tabs.

18. An absorbent article, comprising:
-
a chassis having a front waist region, a back waist region, and a crotch region extending between said front and back waist regions; an outer cover member and a bodyside liner extending longitudinally between said front and back waist regions; an absorbent body structure sandwiched between said outer cover member and said bodyside liner; a unitary elastomeric structure attached to at least one of said front waist region or said back waist region, said elastomeric structure extending completely across said respective waist region and extending beyond lateral sides of said chassis so as to form elastomeric attachment tabs; and wherein said elastomeric structure is bonded to said waist region with a varying bond pattern resulting in a varying modulus of elasticity across said elastomeric waistband portion. - View Dependent Claims (19, 20, 21, 22, 23)
