Abstract
A waste disposal system with a compact footprint. The waste disposal system device accepts a cassette having a length of tubular liner film. The waste disposal device and cassette can have similar cross-sectional geometry. The waste disposal device and/or cassette comprise a first wall, a second wall, and a first included angle defined therebetween between about sixty and about one-hundred twenty degrees.
Claims43
A film cassette for receiving waste, comprising:
- an outer wall edge defining an outer perimeter in a first XY plane;
- an inner wall edge defining a central passage and an inner perimeter in the first XY plane, comprising:
- an inner first side edge;
- an inner second side edge, wherein the inner first side edge and the inner second side edge have an inner included angle therebetween in the first XY plane in the range of about 60 degrees to about 120 degrees;
- an inner front edge, extending between and connected to the inner first side edge and the inner second side edge;
- and
- a length of flexible liner film having, during use, an open end for receiving waste and a closed end for storing waste within the liner film;
- wherein the inner wall edge of the film cassette has a shape that is generally triangular, a Reuleaux triangle, a conical section, a frusto-conical section, or combinations thereof, wherein the shape is with respect to the inner perimeter, and
- wherein the open end of the liner film is attached to the film cassette within the outer perimeter and the inner perimeter such that the liner film extends downwardly from the film cassette to the closed end, and
- wherein the liner film passes downwardly through the central passage in order to store waste within the liner film.
