Abstract: A receptacle adapted to be disposed for receiving, by gravity, waste discharges from a person is an elongated container having an elongated aperture defined at the top thereof for receiving waste into the container. The container has side and end surfaces specially formed with concave surfaces to direct laterally-moving fluid waste in the container, the motion being caused by movement of the receptacle, in a generally upward direction, and the container has a portion for thereafter directing the fluid downward, back on itself to dampen sloshing or wave motion to prevent spillage and splashing. In another aspect, the receptacle is disposed in waste-receiving relationship to a person on a chair for an incontinent disabled person, the chair having an apertured cushion disposed over the receptacle which is mounted to be removed from the chair.
