Abstract

A disposable diaper for incontinent adults comprising an absorbing pad covered by a liquid-impermeable external sheet (3) and a non-woven liquid-permeable inside sheet (4). This diaper is provided with four longitudinal folding lines, whereby it can be folded into several superposed levels (7a, 7b, 7c) when in the position of usage. Stretched elastic cords (13a) and (13b) are inserted between the sheets (3) and (4) near and parallel to the longitudinal edges. Prior to use two elastic belts (14a, 14b) are fixed on the same longitudinal edge (9a), one in the front zone (12) and the other in the rear zone (11) so as to clamp the cord (13a). The diaper has improved hermeticity and facilitates its emplacement by the user.
