Abstract

Absorbent articles having a unique elastic waist feature improving dynamic fit as well as containment characteristics. The elastic waist feature preferably comprises an interconnecting panel zone, a first flexural hinge zone joining the interconnecting panel zone with the containment assembly, an elasticized waistband, and a second flexural hinge zone joining the elasticized waistband with the interconnecting panel zone. The elasticized waistband comprises a shaping panel zone; a waistline panel zone; and a predisposed, resilient, waistband flexural hinge zone joining the shaping panel zone and the waistline panel zone. The waistband flexural hinge zone is predisposed to allow the panel zones to flexurally bend about a defined axis or zone is resilient to provide a restoring force/moment that returns the panel zones to their preceding in-use configuration, especially when the elasticized waistband has been pretensioned by a closure system. The closure system dynamically creates/maintains lateral tension through the elasticized waistband thereby allowing the elasticized waistband to more dynamically expand and contract with the motions of the wearer. The absorbent article additional…
