Abstract

Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants, feminine hygiene garments and the like, that have a unique waist feature that improves the dynamic fit as well as the containment characteristics of the absorbent article. Such absorbent articles comprise a chassis assembly preferably comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core positioned between the topsheet and the backsheet; an extensible back waist feature; and a closure system for maintaining the absorbent article on the wearer. The extensible back waist feature provides an extensible feature that provides a more comfortable and contouring fit by initially conformably fitting the diaper to the wearer and by sustaining this fit. The extensible back waist feature has a hip panel, a central waistband panel, and a pair of side panels. The force/extension characteristics of each panel is designed to provide such improved fit and containment. While each panel of the extensible waist feature may be constructed from a number of extensible materials, the panels preferably comprise a structural elastic-like film web. The structural elastic-like film (SELF) web exhibits an elastic-like behavior in the direction of elongation without the use of added elastic materials. The configuration of the SELF web in each panel has specific characteristics to provide the desired force/extension characteristics of each panel.
