Abstract

A waste disposal system includes a generally rigid support skeleton defining an interior space configured to receive refuse and a flexible, bag-like member supported by, and enclosing therewithin the support skeleton. The waste disposal system may be advantageously configured to provide a litter box for felines and the like.

Claims

1. A litter box for felines and the like comprising:

a generally box-like support skeleton, said skeleton deployable from a first, substantially flat configuration which encloses substantially no interior volume, to a second, self-supporting configuration which defines an interior volume, said skeleton including, when in said second configuration, a generally planar base and four walls, of equal heights, encircling the periphery of the base in a non-planar relationship therewith, one of said walls including an opening therethrough communicating with the interior volume; and

,

a flexible, bag-like member enclosing, and supported by, the skeleton when in said second configuration,

said bag-like member including a closed bottom disposed proximate the base of the skeleton, said bag-like member further including a pair of openings defined therein, a first opening disposed proximate the opening in said wall and a second opening, larger than the first opening, disposed proximate the top of the skeleton.

2. A litter box as in claim 1, wherein said support skeleton is deployable from said first configuration to said second configuration and from said second configuration to said first configuration while disposed within the bag-like member.

3. A litter box as in claim 1, wherein said support skeleton includes a generally closed bottom.

4. A litter box as in claim 3, wherein said closed bottom is provided by a plurality of flaps disposed in overlapping relationship.

5. A litter box as in claim 1, wherein said support skeleton is fabricated from a moisture resistant material.

6. A litter box as in claim 1, wherein said support skeleton is fabricated from a material selected from the group consisting essentially of:

wood, metal, synthetic polymeric resins, cardboard and paper.

7. A litter box as in claim 1, wherein said support skeleton is configured as a generally rectangular, box-like member having a base with two longer sides and two narrow sides and wherein the opening in one of said walls is disposed along one of the longer sides of the base.

8. A litter box as in claim 1, wherein said first opening in the bag-like member and the opening in the support skeleton are sufficiently large to permit passage of a domestic cat therethrough.

9. A litter box as in claim 1, wherein at least one of said skeleton and bag-like member includes a material therein selected from the group consisting essentially of:

deodorizers, bacteriocides, and moisture resistant materials.

10. A litter box as in claim 1, wherein said interior volume includes a volume of absorbent material therein.

11. A litter box as in claim 1, wherein said bag-like member is sufficiently large to enclose the entirety of the support skeleton.

12. A litter box as in claim 1, wherein said box-like support skeleton includes a plurality of corners and at least one of said corners is truncated so as to present a rounded profile, said rounded profile minimizing puncture of the bag-like member by said at least one corner.

13. A litter box as in claim 1, wherein said bag-like member is fabricated from a moisture impervious, synthetic organic polymeric material.

14. A litter box as in claim 1, wherein said bag-like member includes a draw-string for the closing of said second opening.

15. A litter box as in claim 1, wherein said bag-like member includes a pair of integral handles and wherein said support skeleton includes attachment means for retaining said handles.

16. A litter box as in claim 1, wherein said box-like support skeleton has an open top.

17. A litter box as in claim 1, wherein said box-like skeleton has a closed top.

18. A litter box as in claim 1, wherein said box-like support skeleton is open at the bottom.

19. A litter box as in claim 2, wherein said skeleton is fabricated from a resilient, foamed polymeric material.

20. A litter box for felines and the like comprising:

a generally box-like support skeleton, said skeleton deployable from a first, substantially flat configuration which encloses substantially no interior volume, to a second, self-supporting configuration which defines an interior volume, said skeleton including, when in said second configuration, a generally planar, rectangular base comprised of at least two base flaps disposed in at least partially overlapping relationship, said skeleton further including four walls of equal heights encircling the periphery of the base in a perpendicular relationship therewith, a first pair of said walls disposed in a mutually planar, spaced apart relationship and a second pair of said walls which are substantially longer than said first pair of walls and disposed in spaced apart planar relationship and at right angles to said first pair of walls, one of said second pair of walls including an opening therethrough, the support skeleton further including a pair of support flaps associated with one of said pair of walls, said flaps disposed so as to support the base flaps when the skeleton is disposed in the second configuration; and

a flexible bag enclosing, and supported by, the skeleton when in said second configuration, said bag including a closed bottom disposed proximate the base of the skeleton, said bag further including a pair of openings defined therein, a first opening disposed proximate the opening in said wall and a second opening, larger than the first opening, disposed proximate the top of the skeleton.
