Abstract

Waste disposal device including a housing defining a waste compartment for receiving enclosed waste and arranged to removably receive a cartridge containing a length of flexible tubing which operatively receives waste therein, a retention mechanism for holding a quantity of waste received in the tubing and a rotation mechanism for rotating the retention mechanism when the quantity of waste is held thereby and while the cartridge is stationary in order to twist the tubing and enclose the held quantity of waste. The compartment in the housing receives the enclosed waste. The waste is thus rotated while the cartridge is held against rotation thereby enabling the formation of the twist above the waste to enclose or encapsulate the waste. A pushing mechanism may be provided on a cover of the device to push the waste into engagement with the retention mechanism.
