Abstract:
1. A disposable diaper, comprising: a front waist region, a rear waist region, and a crotch region extending between the front and the rear waist regions in a longitudinal direction of the diaper, wherein said crotch region has an inner surface adapted to face a wearer's skin and an outer surface adapted to face away from said wearer's skin, leg-encircling elastic members attached to lateral edges of the crotch region, respectively, a feces receiving space defined between said leg-encircling elastic members and extending along said lateral edges, a pair of leak-barrier cuffs extending in the longitudinal direction; and a pair of contracting members between said leak-barrier cuffs, spaced from each other in said transverse direction, extending across said intermediate portion, and elastically contractible in said longitudinal direction; and wherein each of said contracting members includes front and rear sections and an intermediate section extending between the front and rear sections in the longitudinal direction, wherein said front sections are fixed to said inner surface at positions anterior to a line bisecting a length of said intermediate section in said longitudinal direction, said rear sections are fixed to said inner surface at positions posterior to said intermediate section, and said intermediate sections are free of direct attachment to said inner surface so as to be elastically contractible in the longitudinal direction; and upon contraction of said contracting members, said crotch region is folded downward in a vertical direction along said front folding guide and said rear folding guide to form, between said contracting members in the vicinity of said intermediate section, said feces receiving space, the disposable diaper further includes a block-shaped elastic member bonded directly onto the inner surface at the intermediate portion of the crotch region for rendering said intermediate portion elastically deformable.
