ABSTRACT:
A two piece portable toilet is described. The toilet includes a bowl unit which defines a toilet bowl having a discharge opening, and a reservoir for a flushing liquid, said reservoir having a normally closed filler opening. A holding tank is normally disposed below and supports the bowl unit. The holding tank has a top wall and defines a waste holding chamber having an inlet opening in said top wall for communication with the discharge opening of the toilet bowl. The chamber also has a normally closed outlet opening. The top wall of the tank is contoured to define a depression around the holding chamber inlet opening and, on opposite sides of the depression, surfaces for supporting said bowl unit. Coupling means normally maintain the bowl unit and holding tank in co-operating relationship when the toilet is in use. The coupling means allow the unit and tank to be separated at appropriate times. The toilet also includes pump means communicating with the reservoir in the bowl unit and with the toilet bowl and operable in use to deliver flushing liquid from the reservoir into the bowl. Valve means are also provided for controlling discharge of material from the toilet bowl into the holding chamber. The valve means are disposed in the depression in the top wall of the holding tank and includes a flap-form closure member which is pivotable about an axis generally normal to the axis of the discharge opening of the toilet bowl. The closure member is movable between a position in which the member prevents communication between the discharge opening of the bowl and the waste holding chamber, and a position in which the closure member has pivoted downwardly clear of the opening to allow discharge of material from the toilet bowl into said chamber. A valve operating means is normally disposed below and supports the closure member in its closed position and is retractable to allow the closure member to pivot downwardly about its said axis and allow communication between the discharge opening of the bowl and the inlet of the waste holding chamber.
