Abstract
A cassette for disposing waste is provided having a variable cross-sectional geometry. The cross-sectional geometry varies at least at two locations around the periphery of the cassette such that a first maximum height at a first location is different than a second maximum height at a second different location, and the first maximum width at a first location is different than a second maximum width at a second location.
Claims9
A film-dispensing cassette for a waste disposal device, comprising:
- a body configured to be removably coupled to a housing of a waste disposal device, the body defining:
- a central passage;
- a liner cavity for containing a supply of liner film, said liner cavity extending around said central passage, said liner cavity having a cross-sectional geometry that varies around a perimeter of said body at least at two different points, the liner cavity defined by:
- an inner cavity wall defining a periphery of the central passage on one side and an inner surface of the liner cavity on an opposite side, at least a portion of the inner cavity wall being curved along the periphery of the central passage,
- a bottom cavity wall extending from the inner cavity wall, the bottom cavity wall connected to the inner cavity wall along the periphery of the central passage,
- an outer cavity wall extending upwardly from the bottom cavity wall, and
- an opening between an upper edge of the inner cavity wall and an upper edge of the outer cavity wall, the opening having a variable width along the perimeter of the body;
- and
- a top panel connected to the upper edge of the inner cavity wall or the upper edge of the outer cavity wall, the top panel having an inconstant width along the perimeter of the body.
