Absorbent article with elasticized region

Abstract

A disposable absorbent article may include a topsheet, backsheet, absorbent core, and an elasticized region disposed in a leg gasketing system. The elasticized region may include a first elastic member and a second elastic member. The first elastic member is joined to the article at both a first contraction starting point and a first contraction ending point, and the second elastic member is joined to the article at both a second contraction starting point and a second contraction ending point. The first contraction starting point is disposed on a first start axis and the second contraction starting point is disposed on a second start axis, wherein the second start axis is different than the first start axis.

What is claimed is: 
     
         1 . A disposable absorbent article comprising:
 a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet, a first waist region having a first waist edge, a second waist region having a second waist edge, a crotch region disposed between the first and second waist regions, and a first longitudinal edge and a second longitudinal edge;   a chassis periphery defined by the first and second waist edges and the first and second longitudinal edges; and   a waist region comprising an elasticized region, the elasticized region comprising a first elastic member and a second elastic member, each extending in a direction of extension, and wherein the first elastic member is disposed adjacent to the second elastic member;   wherein the first elastic member is joined to the waist region at both a first contraction starting point and a first contraction ending point and the second elastic member is joined to the waist region at both a second contraction starting point and a second contraction ending point;   wherein the first contraction starting point is disposed on a first start axis that is substantially perpendicular to the direction of extension and the second contraction starting point is disposed on a second start axis that is substantially perpendicular to the direction of extension; and   wherein the second start axis is different than the first start axis such that the first contraction starting point and the second contraction starting point are disposed on different longitudinal axis, wherein the longitudinal axis is substantially perpendicular to the direction of extension; and   wherein the first contraction starting point, the second contraction starting point, the first contraction ending point, and the second contraction ending point are positioned laterally outboard the absorbent core.   
     
     
         2 . The disposable absorbent article of  claim 1  wherein:
 the first contraction ending point is disposed on a first end axis that is substantially perpendicular to the direction of extension of the elastic members; 
 the second contraction ending point is disposed on a second end axis that is substantially perpendicular to the direction of extension of the elastic members; and 
 wherein the first and second end axes are different such that the first contraction ending point and the second contraction ending point are disposed on different longitudinal axis. 
 
     
     
         3 . The disposable absorbent article of  claim 1  wherein the chassis periphery comprises a hourglass shape. 
     
     
         4 . The disposable absorbent article of  claim 1  further comprising an attachment zone wherein in the attachment zone:
 the first elastic member is joined to the waist region at two attachment intervals wherein the two attachment intervals are separated by an unattached span; and 
 the second elastic member is continuously joined to the waist region. 
 
     
     
         5 . The disposable absorbent article of  claim 1  wherein
 the first elastic member comprises a first strain, ε 1 ; 
 the second elastic member comprises a second strain, ε 2 ; and 
 the first strain, ε 1 , is different than the second strain, ε 2 . 
 
     
     
         6 . The disposable absorbent article of  claim 1  where the first elastic member and/or the second elastic member is joined to the waist region by strand coating.
