Absorbent article with dynamic elastic waist feature comprising an expansive tummy panel
First Claim
1. A disposable absorbent article having a lateral centerline, a lateral direction defined as the direction parallel to said lateral centerline, a longitudinal centerline, a longitudinal direction defined as the direction parallel to said longitudinal centerline, a first waist region, and a second waist region, the absorbent article comprising:
- a containment asssembly comprising a liquid pervious topsheet, a liquid impervious backsheet joined with said topsheet, and an absorbent core positioned between said topsheet and said backsheet, said absorbent core having side edges and waist edges;
an elastic waist feature at least extending longitudinally outwardly from one of said waist edges of said absorbent core, said elastic waist feature comprising an elasticized waistband, said elasticized waistband having extension forces less than or equal to about 400 grams force at extensions of between about 25 mm and about 50 mm; and
a closure system disposed on the absorbent article so as to be longitudinally aligned with said elasticized waistband for maintaining lateral tension through said elasticized waistband.

Abstract
Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have a unique elastic waist feature that improve the dynamic fit of the elasticized waistband as well as the containment characteristics of the absorbent article. The elastic waist feature comprises an "expansive tummy panel" that is capable of expanding well-beyond the dimensions of the absorbent article set by the primary fastening system (and the original dimensions of the end edge) so as to accommodate wearers, especially large infants, with large expansile waists so as to reduce the sagging/slipping of the absorbent article. The extension forces of the elasticized waistband are lower than the extension forces of the elasticized side panels so as to accommodate such expansion. In preferred embodiments of the elastic waist feature, the elasticized waistband is formed from a stretch laminate.
