Abstract: An automatic closure assembly for use with an outhouse or pit commode is disclosed which includes a frame having open upper and lower ends attached to the underside of a bench so as to frame an opening therein over which a toilet seat is hingably mounted atop the bench. The assembly also includes a pair of wedge shaped cradle members which are pivotally attached to front and rear surfaces of the frame which tilt in opposite directions from one another so as to open and close a lower end of the frame. The geometry of the cradle members is such that their centers of gravity are substantially spaced apart from their pivot points so as to provide a gravitational bias of each cradle member tending to urge it at all times toward its closed position against the other cradle member so as to seal the bottom end of the frame to inhibit odors from circulating in or about the outhouse when the assembly is not in use.

Abstract: A portable toilet device has a disposable waste receiving bag situated therein. The device is operable from an open or in-use position to a closed or non-use position which causes rotation of the waste receiving bag to temporarily close or seal the bag.
