Abstract
Abstract Disposable diapers having elasticized waistbands which allow the diapers to breathe and which reduce the incidence of waistband rollover. The waistbands are formed by affixing elastic elements between the topsheets and the backsheets (in the waistband region of the diapers) using regularly spaced, transversely extending regions of securement. Regions of nonsecurement are formed between pairs of the regions of securement thereby forming channels which allow the diaper to breathe and also forming corrugations which tend to inhibit waistband rollover.
