Abstract
Abstract The waste container and packer includes an open top cylindrical receptacle, a plunger reciprocally movable within the receptacle, and a seat on the upper end of the plunger. A snap ring on the rim of the receptacle guides the plunger in its reciprocal movement. A disposable liner for the receptacle has the upper end thereof folded over the rim and secured to the receptacle when the snap ring is mounted in place. Waste in the liner is packed or compressed by the weight of a person supported on the seat.
