Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 148 words
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.
Claim 2
Dependent Claim 148 words
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.
Claim 3
Dependent Claim 36 words
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.
Claim 4
Dependent Claim 16 words
A litter box as in claim 1, wherein said support skeleton includes a generally closed bottom.
Claim 5
Dependent Claim 22 words
A litter box as in claim 3, wherein said closed bottom is provided by a plurality of flaps disposed in overlapping relationship.
Claim 6
Dependent Claim 18 words
A litter box as in claim 1, wherein said support skeleton is fabricated from a moisture resistant material.
Claim 7
Dependent Claim 31 words
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.
Claim 8
Dependent Claim 50 words
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.
Claim 9
Dependent Claim 33 words
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.
Claim 10
Dependent Claim 34 words
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.
Claim 11
Dependent Claim 18 words
A litter box as in claim 1, wherein said interior volume includes a volume of absorbent material therein.
Claim 12
Dependent Claim 22 words
A litter box as in claim 1, wherein said bag-like member is sufficiently large to enclose the entirety of the support skeleton.
Claim 13
Dependent Claim 48 words
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.
Claim 14
Dependent Claim 21 words
A litter box as in claim 1, wherein said bag-like member is fabricated from a moisture impervious, synthetic organic polymeric material.
Claim 15
Dependent Claim 21 words
A litter box as in claim 1, wherein said bag-like member includes a draw-string for the closing of said second opening.
Claim 16
Dependent Claim 29 words
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.
Claim 17
Dependent Claim 16 words
A litter box as in claim 1, wherein said box-like support skeleton has an open top.
Claim 18
Dependent Claim 15 words
A litter box as in claim 1, wherein said box-like skeleton has a closed top.
Claim 19
Dependent Claim 17 words
A litter box as in claim 1, wherein said box-like support skeleton is open at the bottom.
Claim 20
Dependent Claim 18 words
A litter box as in claim 2, wherein said skeleton is fabricated from a resilient, foamed polymeric material.
Claim 21
Dependent Claim 246 words
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.
Claim 22
Dependent Claim 246 words
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.
