Disposable Diaper

October 8, 2002

Patented is a disposable diaper with a body that includes a front face portion applied to the wearer’s abdomen and an intermediate portion applied to the crotch. The diaper also features a back face portion, in which a longitudinal direction is taken from the front to the back face portion and a transverse direction is taken in a direction perpendicular to the longitudinal direction and comprises a topsheet directed toward a liquid-receiving side, an outer sheet and an absorbent core sandwiched in between the topsheet and the outer sheet. The topsheet is liquid-permeable for covering a transverse center of the absorbent core and is jointed on two transverse sides directly or indirectly to the outer sheet. In the region containing a longitudinal center of the intermediate portion, joint boundaries between the topsheet and the outer sheet enter farther on the transverse center side than the absorbent core’s two transverse side ends.
