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.

First claim

The invention claimed is:

1. 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.

2. The film cassette according to claim 1 , wherein the inner included angle is between about 60 degrees and about 105 degrees.

3. The film cassette according to claim 2 , wherein the inner included angle is between about 75 degrees and about 90 degrees.

4. The film cassette according to claim 1 , wherein outer wall edge is defined by an outer first side edge, and outer second side edge, and an outer front side edge, wherein the outer first side edge and the outer second side edge from an outer included angle of between about 60 degrees and about 120 degrees.

5. The film cassette according to claim 1 , wherein the outer wall edge is a shape that is different from the central passage as defined by the inner wall edge.

6. The film cassette according to claim 1 , wherein the cassette has a maximum widthwise dimension located proximal the inner front edge, and wherein the cassette has a maximum depthwise dimension extending along a bisector of the inner included angle.

7. A cassette for receiving waste, comprising:
a first side edge;
a second side edge, wherein the first side edge and the second side edge have a first included angle therebetween in the range of about 60 degrees to about 120 degrees;
a front edge having a first edge portion and a second edge portion such that said first edge portion and said second edge portion have a second included angle therebetween in the range of about 90 to about 150 degrees; and
a length of flexible liner film having, during use, an open end for receiving waste and a closed end for storing waste,
wherein said cassette is diamond in shape.

8. The cassette of claim 7 , wherein said first side edge, said second side edge and said front edge define a central passage through which said liner film passes in order to store waste.

9. The cassette of claim 8 , wherein said first side edge defines a first side wall extending generally downward, said second side edge defines a second side wall extending generally downward, and said front edge defines a front wall extending generally downward, wherein said first side wall, said second side wall, and said front wall further define said central passage.

10. The cassette of claim 7 , wherein said first side edge, said second side edge and said front edge define an outer edge.

11. The cassette of claim 10 , wherein said first side edge defines a first side wall extending generally downward, said second side edge defines a second side wall extending generally downward, and said front edge defines a front wall extending generally downward, wherein said first side wall, said second side wall, and said front wall further define an outer wall.

12. 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 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 cassette has a maximum widthwise dimension located proximal the inner front edge, and

wherein the cassette has a maximum depthwise dimension extending along a bisector of the inner included angle, and
wherein the open end of the liner film is attached to the film 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 downward through the central passage in order to store waste within the liner film.

13. The cassette according to claim 12 , wherein at least one of said first side edge, said second side edge, and said front edge is arcuate.

14. The film cassette according to claim 12 , wherein the inner front edge further comprises an inner first front edge segment and an inner second front edge segment.

15. The film cassette according to claim 14 , wherein the inner first front edge segment has an inner first end and an inner second end, and the inner second front edge segment has an inner third end and an inner fourth end, the inner first end of the inner first front edge segment connectable to the inner first side edge, and the inner fourth end of the inner second front edge segment connectable to the inner second side edge.

16. The film cassette according to claim 15 , wherein the inner second end of the inner first front edge segment connects to the inner third end of the inner second front edge segment and forms a second included angle between about 60 degrees and about 150 degrees.

17. The film cassette according to claim 16 , wherein the inner first side edge and the inner first end of the inner first front edge segment form a third included angle, and the inner second side edge and the inner fourth end of the inner second front edge segment form a fourth included angle.

18. The film cassette according to claim 17 , wherein the maximum widthwise dimension is between a bisector of the third included angle and the inner front edge such that the maximum widthwise dimension is proximal the inner front edge.

19. The film cassette according to claim 17 , wherein the maximum widthwise dimension is between a bisector of the fourth included angle and the front edge such that the maximum widthwise dimension is proximal the inner front edge.

20. A film cassette for receiving waste, comprising:
an outer wall edge defining an outer perimeter in a first XY plane, comprising:
an outer first side edge;
an outer second side edge, wherein the outer first side edge and the outer second side edge have an outer included angle therebetween in the first XY plane in the range of about 60 degrees to about 120 degrees;
an outer front edge, extending between and connected to the outer first side edge and the outer second side edge; and

an inner wall edge defining a central
