Abstract:
1. A disposable wearing article, comprising: a first surface and a second surface opposite to the first surface; first and second waist regions, and a crotch region extending in a longitudinal direction of said article between the first and second waist regions; a liquid-pervious topsheet adapted to face a wearer's body in use; a liquid-impervious backsheet adapted to face away from the wearer's body in use; a liquid-absorbent core interposed between said topsheet and said backsheet; a pair of water-resistant, longitudinal barrier cuffs each comprising: a pair of tape fasteners extending in the transverse direction outwardly from transversely opposite side sections of the first waist region, respectively, each said tape fastener comprising: a target zone disposed on the first surface in the second waist region and having a plurality of loops releasably engageable with a plurality of hooks of the hook members of said tape fasteners; wherein, in each of said tape fasteners, the first monolithic tape strip consists of: the second monolithic tape strip consists of: the proximal portions of the first and second monolithic tape strips are permanently bonded to and sandwich therebetween the associated side section which is defined by said backsheet and the fixed portion of an associated one of said barrier cuffs, and the hook member is permanently, directly bonded to both the first and second distal portions of the second monolithic tape strip, and is free of direct attachment to the proximal portion of the second monolithic tape strip, whereby the hooks of said hook member are distributed over the first and second distal portions, but not over the proximal portion, of the second monolithic tape strip; and wherein each said tape fastener has a stiffness lower in a second zone where the second distal portion of the second monolithic tape strip extends than in a first zone where the distal portion of the first monolithic tape strip extends; wherein each said tape fastener has a Gurley stiffness in a range of 5.0 to 12 mN in the first zone and a Gurley stiffness in a range of 0.3 to 4.6 mN in the second zone, and wherein, in each of said tape fasteners, the hook member provided on the second distal portion has an area in a range of 1.75 to 8.0 cm an entire dimension, as measured in the transverse direction of the article, of each of said distal portion of the first monolithic tape strip and said first distal portion of the second monolithic tape strip is in a range of 8 to 15 mm; and an entire dimension, as measured in the transverse direction of the article, of said second distal portion of the second monolithic tape strip is in a range of 17 to 22 mm.
