Abstract
Abstract A disposable liner for a receptacle for body wastes, e.g. a bedpan, includes a bag of flexible, moisture-proof sheet material adapted to loosely receive the receptacle therein so that one side of the bag can be depressed into and made to generally conform to the cavity in the receptacle. A flexible member is associated with the depressed side of the bag to project beneath the ledge on the pan overlying the sides of the cavity to retain the side of the bag in operative conformity with the cavity. The mouth of the bag is large enough so that it may be turned back inside out over and under the pan to capture the body wastes and then the mouth sealed to facilitate transportation for disposal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
232 words
A disposable liner for use with a receptacle for body wastes, the receptacle having a bottom and side walls defining a cavity partly overlaid by a peripheral ledge portion forming a seat about a top opening comprising: an open-mouthed bag of moisture-proof pliable sheet material, said bag being large enough to loosely receive the receptacle and to have a side portion of the bag pushed through the opening in the receptacle and generally conformed to the cavity therein for reception of body wastes, the mouth of said bag being large enough to be turned back over the receptacle and to turn the bag inside-out to capture the wastes and then have the mouth sealed to facilitate transportation to disposal without spillage or escape of odors; and deformable means secured to said bag, insertable through the receptacle top opening, and engageable beneath the receptacle ledge portion at at least opposite sides of the opening to retain said bag side portion in general conformance with the receptacle cavity while enabling said bag when inside-out to be readily detached from the receptacle, said deformable means including a plurality of spaced strips of material stiffer than that of said bag extending across the exterior of said bag side portion and having their end portions adapted to engage beneath the ledge portion and their central portions adapted to hold said bag side portion against the receptacle bottom.
