Abstract:
1. A pull-on disposable diaper having a height direction and a transverse direction being orthogonal to said height direction, said diaper being generally symmetric about a center line bisecting said diaper in said transverse direction, said diaper comprising a pants-like covering component having an inner surface facing a wearer's body and an outer surface facing a wearer's garment, said covering component being composed of a front waist region, a rear waist region and a crotch region adapted to cover a wearer's front region, a wearer's rear region and a wearer's crotch region, respectively, said covering component having a waist-hole and a pair of leg-holes, and being provided with an absorbing component which is separate from the pants-like covering component and disposed on said inner surface of said pants-like covering component so as to extend over said crotch region into said front and rear waist regions, said pull-on disposable diaper further comprising: said absorbing component comprising a liquid-absorbent core and a liquid-pervious cover sheet, said core having a generally rectangular shape and having an inner surface and an outer surface, said cover sheet covering at least said inner surface of said inner and outer surfaces of said core, said absorbing component being formed in said crotch region with a first folding guide extending from a middle zone between transversely opposite side edges which extend, in turn, parallel to each other in said height direction to respective said side edges so as to veer toward said front waist region, a second folding guide extending to respective said side edges so as to veer toward said rear waist region and a third folding guide extending in a transverse direction between said first and second folding guides, and said absorbing component being folded on both sides of said center line along said third folding guide so that said core has its outer surface sections facing to each other and along said first and second folding guides so that said core has its inner surface sections facing to each other, and wherein said crotch region is provided on said outer surface of said absorbing component with flaps extending outward of said absorbing component in said transverse direction and defining peripheral edges of respective said leg-holes, said flaps being elastically stretchable in a circumferential direction of said leg-holes, said outer surface of said absorbing component being separated from said flaps at least along said side edges and in vicinities of said side edges and zones separated from said flaps are covered with said cover sheet.
