Disposable diaper
First Claim
1. 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.

Abstract
A disposable diaper includes barrier cuffs around wearer'"'"'s legs. Each of the barrier cuffs longitudinally extends on an inner surface of the disposable diaper and includes a supporting wall section adapted to rise on the inner surface of the diaper and a sealing surface zone which includes a first overhead section extending inwards from the supporting wall section and a second overhead section extending outwards from the supporting wall section. A first elastic member extending along an inner edge of the sealing surface zone in operative association with the first overhead section has an elongation stress higher than that of a second elastic member extending along an outer edge of the sealing surface zone in operative association with the second overhead section. The barrier cuffs thus constructed provide a good fit around a wearer'"'"'s legs to prevent body fluids from leaking.
