Abstract
A disposable, absorbent pants-type diaper includes a front-part (1), a back-part (2), a crotch-part (3) between the front and back parts (1, 2), at least two side-closure parts (12, 13) which mutually join parts of the side-edges (4, 5) of respective front and back parts, so that the pants will present a waist opening (9) and two leg openings (10, 11). The diaper pants further include an elongated absorbent pad (14), an inner casing layer (15), and an outer casing layer (16). At least one of the respective front and back parts (1, 2) has at least one elastically stretchable region (29, 30). The crotch-part (3) is essentially non-stretchable in relation to the stretchable region (29, 30). At least one of respective end-parts (17, 18) of the absorbent pad (14) is disposed within one of the elastically stretchable regions (29, 30), while the center-part (19) of the absorbent pad is disposed within the relatively non-stretchable crotch-part (3) of the pants.
