Patent ID: 7160282

Claim:
A disposable wearing article comprising: a chassis defining front and rear waist regions and a crotch region extending between said waist regions and a liquid-absorbent base panel extending across said crotch region into said front and rear waist regions; a pair of side flaps provided on the chassis that extend along transversely opposite side edges of said liquid-absorbent base panel in a longitudinal direction; a pair of liquid-impervious leak-barrier cuffs extending in said longitudinal direction that are attached to said pair of side flaps, each of said leak-barrier cuffs respectively having: a proximal side edge portion fixed to said side flap and extending said longitudinal direction; a distal side edge portion extending in said longitudinal opposed to said proximal side edge portion; an inner surface that faces toward a transverse center of the chassis; upper and lower portions between said proximal and distal side edge portions; longitudinally opposite fixed end portions collapsed outward in a transverse direction and fixed to said front and rear waist regions in such a collapsed state; and stretchable elastic members extending in said longitudinal direction secured in a stretched state to said distal side edge portions of said leak-barrier cuffs, said disposable wearing article further comprising: liquid-absorbent side panels covered with liquid-pervious sheets and extending in said longitudinal direction, said liquid-absorbent side panels being attached to opposed inner surfaces of said leak-barrier cuffs so that said leak-barrier cuffs rise on said chassis as said elastic members contract and said liquid-absorbent side panels also rise on said chassis as said leak-barrier cuffs rise on said chassis.
