ABSTRACT:
A disposable toilet receptacle includes a bag and a funnel made of a sheet-like liquid-impermeable material, such as plastic film. The plastic film of which the bag is made may be a vapor barrier film. The top edge of the bag has a closure. The tapering body of the funnel is connected to the interior of the bag along a line extending between the side edges of the bag that defines a boundary between an upper chamber and a lower chamber. The portion of the funnel having the wide opening or inlet is disposed in the upper chamber, and the portion of the funnel having the narrower opening or outlet is disposed in the lower chamber. The lower chamber may have in it a gellable hydrophilic material that absorbs liquid waste. The portion of the funnel disposed in the upper chamber is, when fully extended, longer than the upper chamber. The outlet end of the funnel may be a flutter valve that prevents backflow of waste. To use the bag, a user opens the closure and extends the funnel. The user can then support the bag in preparation for use as a toilet by draping the inlet end of the funnel over the rim of such a bucket or other support structure. After use, the funnel can be stuffed into the upper chamber. The user can then close the closure, sealing the soiled funnel inside the upper chamber.
