Abstract
A disposable diaper comprises a liquid-impervious outer sheet (2), defining a narrower crotch region (27) between two wider end or belt regions (28, 29), an absorbent pad (22), fastening members (24) for closing the diapers, and elastic members (4) attached under tension to the impervious sheet (2) on both sides of the absorbent pad (22), substantially over the whole length of the impervious sheet, with a higher tension in the crotch region (27) than in the end regions (28, 29), having, in the two end regions (28, 29), sections (4c) converging in the direction of the transverse edges of the impervious sheet, so that the elastic members (4) form an elastic barrier which practically surrounds the absorbent pad (22) and provide the impervious sheet both with a lengthwise elasticity in the crotch region and a transverse elasticity in the end regions.
