ROGERS, BERESKIN & PARR C A N A D A INVENTION: PORTABLF TOILET INVENTOR: JOHN M. STEWART ABSTRACT OF THE DISCLOSURE A two-piece portable toilet is constructed with a bowl unit supported on a holding tank. In a preferred embodiment of the invention, a friction fit is used to secure the bowl unit to the holding tank at the front of the toilet. The friction fit is provided by roughened vertical surfaces which are pressed horizontally against one another as the bowl unit is seated vertically on the holding tank. In the preferred embodiment the roughened surfaces are provided on an inner wall of a recess at the bottom of the bowl unit, and corresponding roughened surfaces are provided on the sidewall of a projection which extends upwardly from the holding tank to be received in the recess during seating of the bowl unit. Elastic deformation of portions of the bowl unit and holding tank ensure that the roughened surfaces are biased against one another to resist removal of the bowl unit.
