Abstract
A waste disposal device comprises a container having a lid. An externally accessible actuation mechanism comprising a rack and a pinion is connected to the lid, and is operatively configured to interface with a foot pedal. When the actuation mechanism is actuated by pressing the foot pedal, the lid opens, while the rack skips over the pinion. When the foot pedal is released, the rack engages the pinion, which in turn closes the lid and spins a cartridge of the device one revolution.
