Abstract

A diaper (1A) comprises a liquid absorbent core (2) extending between front and rear trunk regions (5, 7), a liquid-permeable first sheet (3) covering the upper and lower surfaces (11, 12) of the core (2), and a liquid-impermeable second sheet (4). In the diaper (1A), a dehiscence region (13) longitudinally extending through and between the upper and lower surfaces (11, 12) of the core (2) is formed in the front trunk region (5) and in a below-the-crotch region (6). The cover upper section (14) of the first sheet (3) extends from the upper surface (11) of the core (2) through the dehiscence section (13) to emerge below the dehiscence section (13), while the cover lower section (15) of the first sheet (3) extends downward from the dehiscence section (13) of the core (2), these upper and lower sections (14, 15) being developed transversely outward around the dehiscence section (13), whereby a penis receiving bag (16) is defined below the dehiscence section (13).

Description

technical field [0001] The present invention relates to a disposable diaper for absorbing and containing body exudates. Background technique [0002] Japanese Patent Publication No. 1994-178788A discloses a disposable diaper comprising a liquid-permeable first layer facing the wearer's body, a liquid-impermeable layer opposite to the first layer, and a liquid-impermeable layer between the two layers. An absorbent core and a pair of flap members attached to the upper surface of the first layer and extending longitudinally. The tab members each have a fixed side region for covering the core and a free region not fixed to the first layer. The free regions extend inwardly in the transverse direction of the diaper from the respective fastening side regions. [0003] In the case of the diapers disclosed in the above-cited publications, the distance between the fixed side regions of each flap member and the length from the fixed side region to the associated free region are defin...
