Abstract:
A disposable diaper having a front waist region, a rear waist region and a crotch region therebetween, said diaper including a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core disposed therebetween, and further including a pair of flexible barrier cuffs extending in a longitudinal direction along said crotch region into said front and rear waist regions, said pair of flexible barrier cuffs being elastically stretchable/contractible in said longitudinal direction due to an effect caused by a provided plurality of elastic members; each of said pair of flexible barrier cuffs including a supporting wall section which extends upwardly from an inner surface of said diaper and a sealing surface zone which includes a first overhead section extending inwards from said supporting wall section and a second overhead section extending outwards from said supporting wall section;wherein in said sealing surface zone, said plurality of elastic members extend in parallel one to another in said longitudinal direction along said crotch region into said front and rear waist regions and are secured to said sealing surface zone under tension in said longitudinal direction so that an elastic member lying along an inner edge of said sealing surface zone has an elongation stress higher than elongation stresses of the remaining ones of said plurality of elastic members.
