Abstract
A disposable diaper includes a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core therebetween. A pair of contractible leg-gasket cuffs extend outward beyond transversely opposite side edges of the absorbent core and a pair of contractible barrier cuffs extend adjacent the side edges of the absorbent core and are biased to rise from an upper surface of the top sheet above the absorbent core. Each of the barrier cuffs is made of a nonwoven fabric and each of the leg-gasket cuffs is formed with a portion of the nonwoven fabric extending outward and a portion of the backsheet extending outward beyond the side edge of the absorbent core and bonded onto the extending portion of the nonwoven fabric. A reinforcing sheet is bonded to an upper surface of each of the leg-gasket cuffs along its outer side edge in order to enhance a tensile strength of the leg-gasket cuff. The reinforcing sheet is made of a nonwoven fabric.
