ABSTRACT:
A portable toilet is provided with a bowl having an outlet port in its bottom, this being closed by a yoke shaped, pivotal valve member movable between a first position in which it closes the outlet port and a second position in which it uncovers the port. An actuation member moves relative to the valve member and cooperating cam surfaces on the valve member and actuation member urge the valve member upwardly to seal the outlet port upon such relative movement.
