Abstract
An elasticized absorbent article, illustrated as an elastic waistband disposable diaper, includes an absorbent panel, a backsheet underlying the absorbent panel, and a liquid-permeable topsheet which overlies the absorbent panel. Each of the backsheet and topsheet includes at least one longitudinal end marginal portion which extends beyond an end edge of the absorbent panel. A waist elastic element is provided which is positioned between the end marginal portions of the topsheet and backsheet for forming an elastic waistband region. Notably, the elastic waistband element is provided with a substantially overall adhesive coating, preferably in either slot-coated or spray-coated filament form, for securement to the associated topsheet. The topsheet is thereby elastically gathered to provide a textured and cushioned surface at the inside region of the waistband for enhanced comfort. The preferred provision of another substantially overall adhesive coating for securing the waist elastic element to the backsheet desirably enhances the containment characteristics of the diaper.
