Abstract
A cassette for a waste disposal device, the cassette including an outer wall, an inner wall, a flexible tubing positioned between the outer wall and the inner wall, and a rim having a top surface and a bottom surface. The rim is positioned between the outer wall and the inner wall and extends from a top surface of the outer wall toward the inner wall. The bottom surface of the rim faces the flexible tubing, and the rim includes a plurality of protrusions on the top surface of the rim to engage with a rotation mechanism of a waste disposal device.
Claims13
A cassette for a waste disposal device, the cassette comprising:
- an outer wall;
- an inner wall connected to the outer wall by a base;
- a flexible tubing positioned between the outer wall and the inner wall;
- and
- a rim having a top surface, a bottom surface and a circumferential edge, the rim being positioned between the outer wall and the inner wall, the rim extending from a top surface of the outer wall toward the inner wall forming a gap between the rim and the inner wall, the bottom surface of the rim facing the flexible tubing, the rim comprising a plurality of protrusions entirely on the top surface and on said circumferential edge of the rim, the plurality of protrusions commencing and extending entirely outward from the top surface of the rim.
A cassette for a waste disposal device, the cassette comprising:
- an outer wall having a top surface, a bottom surface, and two side surfaces;
- an inner wall connected to the outer wall by a base, the inner wall having a top surface, a bottom surface, and two side surfaces;
- flexible tubing positioned between the outer wall and the inner wall;
- and
- a rim having a top surface, a bottom surface, a circumferential edge, and two side surfaces positioned between the outer wall and the inner wall, the rim emanating from the top surface of the inner wall and extending partially towards the outer wall forming a gap between the rim and the outer wall, the bottom surface of the rim facing the flexible tubing, the rim having a plurality of protrusions entirely on the top surface and on the circumferential edge of the rim, the plurality of protrusions commencing and extending entirely outward from the top surface of the rim;
- wherein the cassette can engage with a rotation mechanism of the waste disposal device.
A cassette for a waste disposal device, the cassette comprising:
- an outer wall;
- an inner wall;
- a flexible tubing positioned between the outer wall and the inner wall;
- and
- a rim having a top surface and a bottom surface, the rim being positioned between the outer wall and the inner wall, the rim extending from a top surface of the outer wall toward the inner wall forming a gap between the rim and the inner wall, the bottom surface of the rim facing the flexible tubing, the rim comprising a plurality of protrusions on the top surface of the rim, the plurality of protrusions commencing and extending entirely outward from the top surface of the rim,
- wherein the rim has a portion that extends from a top surface of the outer wall toward the inner wall and a connection portion that connects the rim to the outer wall,
- wherein the connection portion extends downward from the portion that extends from a top surface of the outer wall toward the inner wall,
- wherein the top surface of the outer wall has a projection that projects inward toward the inner wall, and
- wherein the connection portion of the rim has a side portion that is complementary in shape to the projection so that the projection of the outer wall contacts the connection portion.
