November 29, 2011

Japanese researchers have patented a disposable diaper formed by a front body part, a crotch part, and a back body part. The disposable diaper comprises an exterior covering member; an absorber provided on an inner surface of the exterior covering member; a top sheet disposed to cover an upper surface of the absorber and at least partially formed of a liquid permeable material; a back sheet disposed to cover a lower surface of the absorber and formed of a liquid impermeable material; and an SCS, which is a skin contact sheet, disposed above the top sheet and formed so that a portion thereof corresponds to the crotch part, wherein the skin contact sheet has an area that is sufficiently large as so to cover the top sheet, but which is smaller than an overall area of the exterior covering member, and wherein the skin contact sheet has a stool passing opening capable of passing a stool therethrough and a urine passing opening capable of passing the urine therethrough, the skin contact sheet includingan SCS central region formed by extending an inter-opening region, which is a strip-shaped region sandwiched by the stool and urine passing openings and extending in the width direction, by half the length between the stool and urine passing openings in the anterior direction and in the posterior direction,an SCS ventral region located at the ventral side from the SCS central region, and an SCS dorsal region located at the dorsal side from the SCS central region, wherein at least the SCS central region of the skin contact sheet has the stretching force in the width direction, and wherein an inter-opening central region, which is a region located between the stool and urine passing openings, includes a non-stretchable region, which is present only between the stool and urine passing openings, and which is provided in a planar state, having no stretching force in the width direction and in the longitudinal direction.æ
