ABSTRACT:
A portable toilet with a movable spout via which accumulated waste contents are dumped at a suitable sanitary disposal station. The portable toilet has separably mounted seat and holding tank sections which are separated for dumping. The spout is rotatably mounted in an aperture in the top wall of the holding tank and is swung from its stored position to a discharge position extending away from the holding tank and the one dumping the tank. A vent valve is also provided in the top wall of the holding tank and it is manually operated by the person dumping the holding tank so as to vent the head space during dumping, and a waste inlet valve on the tank is locked in its closed position during dumping by an auto lock actuating handle which is located adjacent the vent valve and provides a convenient holding handle for the tank during dumping.
