Abstract
A waste containment garment such as a disposable diaper or a disposable adult brief having elasticized leg flaps which are configured and disposed to present longitudinally extending, inboard facing barrier walls that are positioned outboard from the side edges of the crotch portion of the absorbent core. Such barrier walls function as dams against lateral flow of body wastes, particularly of a runny solids nature.
Claims14
A disposable waste containment garment comprising:
- a liquid permeable topsheet;
- an absorbent core, said absorbent core having side edges;
- a liquid impermeable backsheet;
- said topsheet being secured to said backsheet, and said absorbent core being positioned between said topsheet and said backsheet;
- elastically contractible and longitudinally extending leg flaps, said leg flaps comprising those portions of said backsheet which extend outwardly beyond said side edges of said absorbent core;
- an elastic means for rendering said leg flaps longitudinally elastically contractible;
- and
- a leg cuff member affixed to each of said leg flaps, each of said leg cuff members having an inboard facing barrier wall at least 3/4 inches from said side edges of said absorbent core,
- said barrier wall having a height of at least about 1 mm.
In an improved disposable waste containment garment of the type comprising a topsheet, an absorbent core, a backsheet, and elastically contractible and longitudinally extending leg flaps, said leg flaps comprising portions of said backsheet disposed outboard from the side edges of said absorbent core in at least the crotch region of the core, and elastic means for rendering said leg flaps longitudinally elastically contractible, the improvement wherein each of said leg flaps further comprises means for presenting a longitudinally extending, inboard facing barrier wall for damming lateral flow of body wastes, said barrier wall having a height of at least about one millimeter;
- said means for presenting a longitudinally extending inboard facing barrier wall for damming lateral flow of the user's body wastes comprising a longitudinally extending leg cuff member that is disposed superjacent the user's side of said elastic means, said leg cuff member being sufficiently resilient with respect to the elasticity of said elastic means to be longitudinally contractible thereby so that inwardly facing surface areas of said leg flaps maintain sealing engagement with skin surfaces of said user during use;
- each of said leg flaps further comprising a side edge portion of said topsheet, and wherein each of said leg cuff members is disposed intermediate said elastic means and a said edge portion of said topsheet, and said edge portion of said topsheet is U-channel shaped over said leg cuff member and secured to a substantially planar portion of said backsheet adjacent both the inboard and outboard longitudinally extending edges of said leg cuff member.
