Abstract: A waste disposal system includes a cassette having a latch feature. The latch feature is received within a cassette interface or secured by a cassette interface. A waste disposal device includes a lid that mitigates disturbance of ambient air surrounding the waste disposal device. A liner clamping system has an associated timing that mitigates against air within the interior space of the waste disposal device from travelling upward through the liner clamping system, past the lid (when the lid is in an open configuration) and outward into the surrounding environment.

Abstract: An interface for a waste disposal device includes a cassette and a waste disposal device. Features of the interface reside on the cassette and on the waste disposal device. The interface permits connection of the cassette into the waste disposal device to assist with proper insertion and/or attachment of the cassette to the waste disposal device. In one embodiment, one or more latch features in the waste disposal device engage with one or more ramp features on the cassette body.
