Abstract:
1. A disposable wearing article, comprising: a front waist region, a rear waist region, a crotch region extending between said two waist regions in a longitudinal direction of the article, longitudinally opposite end portions extending across said waist regions in a transverse direction of the article, and transversely opposite side portions extending between said front and rear waist regions in the longitudinal direction, a liquid-pervious topsheet adapted to face a wearer's skin in use, a liquid-impervious backsheet positioned below said topsheet and adapted to face away from the wearer's skin in use, and a liquid-absorbent core interposed between said topsheet and said backsheet so as to extend between said front and rear waist regions, a skin-contactable panel laid above said topsheet in at least a front half of said crotch region, wherein said crotch region is divided by a transverse center line bisecting a longitudinal dimension of said article into said front half and a rear half, and an urine-impervious partition located above said topsheet and below said panel to be interposed between said topsheet and said panel, and extending in the transverse direction in a vicinity of said transverse center line; wherein said panel has transversely opposite side edges bonded to the opposite side portions of said article, respectively, and an intermediate region defined between said side edges, wherein said partition has an upper edge bonded to said panel, a lower edge bonded to said topsheet, and a middle portion between said upper and lower edges, said middle portion being folded in a thickness direction of said article and defining an urine-impervious barrier for (i) preventing fecal material, discharged on the topsheet in the rear half of the crotch region and in the rear waist region, from flowing in the longitudinal direction into the front half of the crotch region and the front waist region and (ii) preventing urine, discharged on the topsheet in the front half of the crotch region and in the front waist region, from flowing in the longitudinal direction into the rear half of the crotch region and the rear waist region to be mixed with and fluidize the discharged fecal material, and wherein the wearing article further comprises a pair of leak-barrier cuffs extending in the longitudinal direction on said topsheet, said leak-barrier cuffs having proximal portions bonded to said side portions of said article, respectively, so as to extend in the longitudinal direction, distal portions extending in the longitudinal direction and normally biased to rise up above said topsheet, and longitudinally opposite ends collapsed in the transverse direction and bonded to said opposite end portions of said article in such a collapsed state, wherein stretchable elastic members extending in the longitudinal direction are contractibly attached to said distal portions of said leak-barrier cuffs; and said panel and said partition are laid between said leak-barrier cuffs, wherein the intermediate region of said panel is bonded directly to the distal portions of said leak-barrier cuffs, respectively, and said intermediate region of said panel is spaced upward from said topsheet as said distal portions of said leak-barrier cuffs rise up under contraction of said elastic members so that the middle portion of said partition extends upwardly in the thickness direction of the article between said topsheet and said panel to define said barrier.
