  • Publication number: 20030217409
    Abstract: A portable waste disposal apparatus includes a stand for receiving a portable bowl and a waste container. The portable bowl includes a receiving port and a disposal port. A disposal port cover permits waste to pass when the cover is in an open position. Waste is prevented from passing through the disposal port when the cover is in a closed position. Actuation of the disposal port cover is independent of pressure within the portable bowl (e.g., due to waste, water, or purging fluid). In various embodiments, the cover slides or pivots between the open and closed positions. A method of disposing of waste includes the step of receiving waste into the portable bowl through the receiving port. The portable bowl is positioned to receive toilet purging fluid through the receiving port when placed within a toilet. The toilet is flushed to discharge the received purging fluid and waste through the disposal port of the portable bowl.

    Abstract: A portable toilet that can be used as a stand alone device or in conjunction with existing toilet facilities. A substantially rectangular seat housing is provided with a pivotally mounted cover member that also acts as a back rest preventing the user, typically a small child, to come in contact with the fixture. A cooperatively positioned opening receives a flanged tubular member trapping a bag for receiving a user's excrements. A pivotally mounted ring secures the tubular member in place. Two pivotally mounted leg assemblies extend outwardly and can be selectively distended 180 degrees resting on the rim of the toilet furniture. When folded inwardly, the leg assemblies are kept in place with a pressure sensitive lock assembly such as hook and loop-type fasteners.

  • Patent number: 5852832
    Abstract: A portable toilet seat comprising a horseshoe shaped base having an inner surface and outer surface, top surface and bottom surface, a front region and an open center. A plurality of telescoping legs extend downward from the bottom surface and retract into appropriately sized recesses which are also disposed about the bottom surface of the base. A lip extends around the perimeter of the inner surface for engaging a deformable waste receptacle such as a bag. The portable toilet bowl is used by retracting the telescoping legs and placing the base on top of a standard toilet bowl to prevent unsanitary bodily contact therewith. When a standard toilet bowl is unavailable, the plurality of legs may be extended to support the base above a surface such as the ground, thus allowing a user to deposit human waste through the center upon said surface, or into the deformable waste receptacle is so desired.
