Abstract
Abstract A disposable waste containment garment which is particularly useful and leakage resistant for bedridden incontinent adults. The garment has side-edge-leakage-guard gutters having closed ends, and longitudinally elasticized distal edges. The gutters and the other garment elements are configured and disposed to substantially obviate inversion or unfolding of the gutters during application and use of the garment. The garment is sized and configured so that, when secured on a user, the elasticized distal edges of the gutters will normally extend along the groin regions of the user, and diverge upwardly across abdominal, hip and lower back areas of the user rather than encircling the thighs of the user. The absorbent core of the garment is preferably sufficiently resilient to cause it to stand away from some lower abdominal and hip regions of the user. This, in conjunction with the gutters being sufficiently flexible and elasticized, causes adjacent portions of the gutters to be biased open. These open portions of the gutters are, in fact, reservoirs which substantially obviate leakage by containing free liquid during urination events when fluid is received in the garment faster than it can be absorbed in the absorbent core of the garment, or whenever free liquid is squeezed out of a portion of the garment as when the weight of a bedridden user is shifted. The ends of the gutters in the waistband regions of the garment may be sealed liquid tight, or be secured closed with edge portions of the absorbent core and/or topsheet disposed therein, or a combination of such sealing and securing.

Claim 4
Dependent Claim
28 words
The disposable waste containment garment of claim 2 wherein said means for securing closed, end portions of said gutters are disposed about edge portions of said absorbent core.
Claim 5
Dependent Claim
47 words
The disposable waste containment garment of claim 3 wherein said means for securing closed, end portions of said gutters are disposed beyond the end edges of said absorbent core such that the ends of said gutters are sealed closed beyond the end edges of said absorbent core.
Claim 6
Dependent Claim
41 words
The disposable waste containment garment of claim 2 wherein said means for substantially obviating inversion of said gutters additionally comprises means for securing closed a first length portion of each of said gutters in the central crotch region of the garment.
Claim 7
Dependent Claim
59 words
The disposable waste containment garment of claim 2 or 5 wherein said means for substantially obviating inversion of said gutters additionally comprises means for securing closed a second length portion of each of said gutters disposed intermediate the central crotch region and the rear waistband region of the garment, the remaining length portions of said gutters being freely openable.
Claim 8
Dependent Claim
37 words
The disposable waste containment garment of claim 6 wherein said gutters are sufficiently flexible and elasticized that, when the garment has been secured on the user, some freely openable length portions of said gutters are biased open.
Claim 9
Dependent Claim
