Abstract: A waste disposal apparatus in which a container main body includes an introduction opening at a top wall portion of the container main body and a discharge opening at a bottom wall portion of the container main body. A cylindrical body having an exit portion is disposed within the container main body and is formed of an elastic material. An exit portion opening/closing device selectively holds the exit portion between a closed state, in which an exit portion of the cylindrical body is pressed and sealed, and an opened state, in which the exit portion of the cylindrical body is opened and the waste accumulated within the cylindrical body is discharged. The exit portion opening/closing device includes exit portion protruding device which, at the time of dumping of the waste, protrudes the exit portion of the cylindrical body to below the bottom wall portion of the container main body and through the discharge opening thereof.

Abstract: A wash water draining device for washing patients in bed has a mattress base, which is formed, for example, by inflatable chambers and is disposed underneath a waterproof bed mattress and slopes the bed mattress from the sides to the center and from the head end to the foot end. A waterproof mattress pad is placed over the mattress and a mattress compressing device is attached centrally to the foot end of the mattress such that a drainage socket of the waterproof mattress pad can be embedded into the resulting and stabilized depression of the bed mattress.

Abstract: A tank for liquidous material is disclosed having a single aperture for accessing an interior volume. A collar formed as a truncated cone circumscribes the aperture to provide sealing with a cap having a mating conical band. A band surface and a collar surface form the only contact between the cap and the collar. A drain fitting may be secured to the collar upon removal of the cap, after which the tank is upended for draining through the drain fitting. A wash fitting attached to the drain fitting sprays the interior of the tank for cleaning. No recesses (grooves) or `O` ring seals, and no protruding, resilient, normal, face seals are used which might trap debris and inhibit complete cleaning. The tapered collar and band create contact forces for sealing that are much greater than the load securing the cap to the collar. The tank, collar and cap may be rotomolded of a single material in a single mold, the cap being severed and trimmed after molding.
