Absorbent article having an extensible outer cover and an extensible bodyside liner
First Claim
1. A disposable absorbent article which defines a front waist section, a rear waist section, an intermediate section which extends between and connects said waist sections, a pair of laterally opposed side edges, a pair of longitudinally opposed waist edges, a longitudinal direction and a lateral direction, said absorbent article comprising:
- a) a substantially liquid-impermeable extensible outer cover;
b) a liquid permeable extensible bodyside liner; and
c) an absorbent body located between said extensible outer cover and said extensible bodyside liner;
wherein said extensible outer cover and said extensible bodyside liner are configured to provide a substantially permanent deformation of at least about 10 percent when subjected to a tensile force of 100 gmf per inch (per 2.54 cm) of width according to a Material Elongation and Deformation Tensile Test set forth herein.
