Abstract: A portable toilet for use in restricted areas or subsequent to natural disaster. The toilet provides a temporary container for noxious products, such as human waste. One embodiment includes a bucket, a valve, and a removable fluid-tight lid. One or more legs space the bucket from the ground, and provide clearance for the valve. A toilet seat or other load bearing arrangement permits deposits into the container. The fluid-tight lid resists escape of noxious contents during transport of the toilet. The contents of a portable toilet may be discharged through the valve into a permanent toilet, RV dump station, or other suitable receptacle. Certain embodiments include provision for a closed-system, clean-in-place wash-down.

Abstract: A container in which to store, transport, and mix a plaster compound. The container has a sealed plastic mix envelope inside which a preferentially rupturable plastic bladder holding a quantity of water is attached by a flexible adhesive film. The mix envelope also contains a quantity of dry plaster mix in a proscribed ratio to the water. A plaster cast may be created with minimal mess by pressing firmly on the envelope to rupture the bladder, kneading the mix envelope to fully wet the plaster mix, forming an opening in the envelope, and pouring the mixed plaster slurry into a mold.
