Abstract
Waste disposal device that receives a waste-containing member includes a container defining a waste-receiving compartment having an opening, a lid having a closed position covering the opening and an open position in which the opening is exposed, and a rotation mechanism arranged in the container to rotate the waste-containing member when present. The rotation mechanism is arranged to rotate the waste-containing member upon closure of the lid without manual handling of the lid. A foot pedal assembly includes a depressible foot pedal and a spring, and is arranged to cause both opening of the lid when the foot pedal is depressed and closure of the lid when the pressing force is removed. The spring is moved against its bias upon depression of the foot pedal and returns to its original state when the pressing force is removed to thereby cause closure of the lid and rotation of the waste-containing member.
