Patent ID: 7666173

Claim:
A disposable wearing article, comprising: a diaper structure which includes a front waist region; a rear waist region; a crotch region extending in a longitudinal direction of the article between said front and rear waist regions; a body-faceable liquid-pervious topsheet; an opposed liquid-impervious backsheet; a liquid-absorbent core interposed between said topsheet and said backsheet so as to extend between said front and rear waist regions; a partition which extends in a transverse direction of said article above said topsheet and is positioned at least in a front half of the crotch region, said partition having transversely opposite lateral zones bonded to transversely opposite side edge portions of the diaper structure and an intermediate zone defined between said lateral zones and free of direct attachment to said diaper structure; and a pair of leak-barrier flaps extending in the longitudinal direction of said article above the topsheet, said leak-barrier flaps having proximal zones bonded to the side edge portions of said diaper structure so as to extend in the longitudinal direction, distal zones extending in the longitudinal direction and biased to rise up above said topsheet, front and rear ends collapsed in the transverse direction and bonded in such collapsed state to vicinities of front and rear ends of said diaper structure, and stretchable and contractible elastic members attached in a stretched state to said distal zones; wherein said partition is laid between said leak-barrier flaps and has transversely opposite regions of said intermediate zone being permanently and directly bonded to the respective distal zones of said leak-barrier flaps so that said intermediate zone is lifted above said topsheet as the respective distal zones of said leak-barrier flaps rise up above said topsheet; a channel is defined between the intermediate zone of said partition and said topsheet to allow free movement of body discharges in the longitudinal direction between the front and rear waist regions; the lateral zones of said partition are bonded to the respective side edge portions of the diaper structure at first bonding sites; and the transversely opposite regions of said intermediate zone are permanently and directly bonded to the respective distal zones of said leak-barrier flaps at second bonding sites which are different from and located between the first bonding sites as seen in the transverse direction.
