Patent ID: 7204830

Claim:
A disposable wearing article having longitudinal and transverse directions, said article comprising: a liquid-impervious chassis having a front waist region, a rear waist region, and a crotch region extending in the longitudinal direction between said front and rear waist regions; a pair of liquid-impervious leak-barrier sheets, wherein said leak-barrier sheets have proximal sections extending in the longitudinal direction along transversely opposite side edges of said chassis, respectively, distal sections provided with stretchable elastic members which extend in the longitudinal direction and are contractibly attached to said distal sections so that said distal sections are biased to rise above said chassis, and longitudinally opposite ends respectively bonded to the front and rear waist regions of said chassis and collapsed in the transverse direction; a body fluid absorbent first panel laid between said pair of leak-barrier sheets, joined to said chassis, and extending over said crotch region and said rear waist region of said chassis; and a body fluid absorbent second panel laid between said pair of leak-barrier sheets and extending over said front waist region and said crotch region of said chassis; wherein said second panel has a front portion joined to said front waist region of said chassis, a rear portion extending in said crotch region, and transversely opposite side edges extending in the longitudinal direction of said chassis; and said rear portion of said second panel has a pair of side sections extending upward from said chassis and being joined to the distal sections of said leak-barrier sheets, and a transversely middle section extending between said side sections so as to be convex upward above said side sections, said middle section at least partially extending upward beyond upper ends of said distal sections of the respective leak-barrier sheets, wherein said chassis and said rear portion of said second panel define therebetween a pocket open toward said rear region; and said side sections of said rear portion of said second panel are joined to said distal sections of said leak-barrier sheets at a level lower than said elastic members; and an absorbent core of said second panel includes a pair of folding guides which are spaced apart from each other by a predetermined distance in the transverse direction, extend in the longitudinal direction, and are formed between the side sections and the middle section in said rear portion of said second panel.
