Disposable diaper
First Claim
1. A disposable diaper comprising:
- a chassis;
a body fluid absorbent structure;
said chassis having a back-and-forth direction, a width direction orthogonal to the back-and-forth direction, a front waist region, a rear waist region and a crotch region extending between the front and rear waist regions;
said absorbent structure comprising a body fluid absorbent panel lying on a side of said inner surface so as to extend on at least the crotch region of said front and rear waist regions and said crotch region and a liquid-pervious sheet covering a surface of said absorbent panel facing a wearer'"'"'s skin;
said absorbent structure being dimensioned in said crotch region to be narrower than said crotch region and having a pair of side edge portions extending in parallel to each other in said back-and-forth direction and, on the side facing said wearer'"'"'s skin, said liquid-pervious sheet covering said absorbent panel being opposed to at least one crossover member extending across said absorbent structure above said absorbent structure in said width direction and having a width in a range of 5 to 250 mm as measured in said back-and-forth direction; and
said transversely opposite end portions of said crossover member being bonded to said diaper in a vicinity of said transversely opposite side edge portions and said intermediate portion defined between said transversely opposite end portions being not bonded to the diaper whereby said intermediate portion being deformable so as to become convex from said outer surface to said inner surface as said chassis and said body fluid absorbent structure are deformed in said crotch region so as to become convex from said inner surface toward said outer surface and to reduce respective widths of these chassis and structure.
