Patent ID: 7744577

Claim:
A disposable pull-on wearing article, comprising: an annular waist region having a front section and a rear section connected together to form a waist-hole; a crotch region being contiguous to a bottom of said annular waist region and cooperating with said annular waist region to form a pair of leg-holes; said annular waist region being provided with tearable lines longitudinally extending from said waist-hole to said leg-holes so that the front and rear sections of said annular waist region can be torn apart; and a pair of connector sheets connecting transversely opposite lateral portions of said front and rear sections, said connector sheets extending in a longitudinal direction of said tearable lines from said waist-hole to respective said leg-holes and each comprising joint zones permanently joined to the respective transversely lateral portions of said front and rear sections, and between said joint zones, a non-joint zone free of direct attachment to said front and rear sections and defining one of said tearable lines; wherein a tensile strength of said non-joint zones is at least 8N/25 mm width in a circumferential direction of the waist-hole, and a tear strength of said non-joint zones is in a range of 0.1 to 12N in said longitudinal direction of the tearable lines, and is lower than those of said transversely opposite lateral portions of said front and rear sections so that said tearable lines are reliably defined by the non-joint zones, and a sheet material of said connector sheets is one selected from the group consisting of: monoaxially oriented breathable, moisture-permeable polyethylene (PE) film with its orientation arranged along the longitudinal direction of the tearable lines; biaxially oriented breathable, moisture-permeable PE film; biaxially oriented air-impermeable PE film; spun-bonded (SB) nonwoven fabric of polypropylene (PP); spun-bonded/melt-blown/spun-bonded (SMS) PP nonwoven fabric having a melt-blown (MB) non-woven fabric layer sandwiched between two SB non-woven fabric layers; laminate of rubber-based hot melt adhesive sandwiched between (i) SB nonwoven fabric of PP and (ii) biaxially oriented breathable, moisture-permeable PE film; and laminate of rubber-based hot melt adhesive sandwiched between (i) SMS PP nonwoven fabric and (ii) biaxially oriented air-impermeable PE film; wherein each of said front and rear sections has opposite inner and outer surfaces wherein the inner surface is directly contactable with a wearer, in use; and each said connector sheet has opposite inner and outer surfaces, the inner surface having a portion directly contactable with the wearer, in use; wherein the inner surface of each said connector sheet is directly attached to the outer surface of one of said front and rear sections, and the outer surface of each said connector sheet is directly attached to the inner surface of the other of said front and rear sections.
