Disposable Diaper

January 31, 2006

A disposable diaper has been patented. The diaper includes a cover member with a front waist region, a back waist region and a crotch region. A liquid-absorbent panel includes a top sheet defining a body-facing surface, a back sheet defining an opposite surface and a liquid-absorbent core there between that extends between the front and back waist regions on an inner side of the cover member. The cover member is elastically contractible in a circumferential direction of a wearer’s waist in at least one of the front and back waist regions. The side edges of the front and back waist regions of the cover member are connected together. Longitudinally opposite ends of the liquid-absorbent panel are supported on inner surfaces of the front and back waist regions. An elastic band extends in an elastically contractible condition in the circumferential direction joining at least one of the longitudinally opposite ends of the panel to at least one of the front and back waist regions. The elastic band is joined to at least one of the longitudinally opposite ends of the panel at least at one point between the liquid-absorbent core and the cover member. The elastic band longitudinally overlaps a portion of the liquid-absorbent core. Ends of the elastic band in the circumferential direction are secured to side edges facing the elastic band.
