Abstract
Abstract A disposable absorbent article such as a diaper having an outer covering layer comprising a liquid pervious topsheet and a liquid impervious backsheet, an absorbent core encased in the outer covering layer, and at least one cuff member extending outwardly from and along an edge of the absorbent core. The cuff member comprises an upper layer, a base layer, a cantilever flap interposed between the upper layer and the base layer and having a fixed edge and a distal edge, and gathering means such as a plurality of elastic members secured to the cantilever flap. The cuff member enhances containment and fit of the absorbent article and minimizes cuff roll-out and collapse during use.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
194 words
A disposable absorbent article having a front waist region, a back waist region and a crotch region, said absorbent article comprising: an outer covering layer; an absorbent core having side edges that is encased in said outer covering layer; a cuff member extending outwardly from and along each side edge of said absorbent core in at least the crotch region, each of said cuff members comprising (i) an upper layer, (ii) a base layer underlaying said upper layer, (iii) an integral cantilever flap interposed between said upper layer and said base layer, said cantilever flap having a fixed edge and a distal edge, said fixed edge being secured to at least said base layer adjacent the longitudinal edge of the absorbent article, said distal edge being disposed inboard of said fixed edge and outboard of said side edges of said absorbent core in at least the crotch region and having at least a portion free from securement to the base layer in at least the crotch region, and (iv) gathering means operatively associated with said cantilever flap for gathering said cantilever flap so that said distal edge is deflected away from said base layer.
Claim 2
Dependent Claim
194 words
A disposable absorbent article having a front waist region, a back waist region and a crotch region, said absorbent article comprising: an outer covering layer; an absorbent core having side edges that is encased in said outer covering layer; a cuff member extending outwardly from and along each side edge of said absorbent core in at least the crotch region, each of said cuff members comprising (i) an upper layer, (ii) a base layer underlaying said upper layer, (iii) an integral cantilever flap interposed between said upper layer and said base layer, said cantilever flap having a fixed edge and a distal edge, said fixed edge being secured to at least said base layer adjacent the longitudinal edge of the absorbent article, said distal edge being disposed inboard of said fixed edge and outboard of said side edges of said absorbent core in at least the crotch region and having at least a portion free from securement to the base layer in at least the crotch region, and (iv) gathering means operatively associated with said cantilever flap for gathering said cantilever flap so that said distal edge is deflected away from said base layer.
