Disposable litter boxes of the type for containing an absorbent material which are suitable for use as cat litter boxes or petroleum and other liquid waste containers wherein the boxes are foldable to create tray-like receptacles which include a bottom wall and upwardly extending ends and side walls which are continuously joined with the bottom wall so that no openings are created therebetween. The receptacles contain an absorbent material which when used may be selectively enclosed for disposal within a closed box created by folding the opposing end walls of the tray into overlapping configuration. The boxes may be sold or shipped in either a flat or folded configuration, and when folded may be sold with an absorbent material already packaged therein.
A disposable litter container for waste absorbent material comprising a foldable box which is convertible from a closed configuration to an open tray in which the absorbent material is retained during use, said tray having a bottom, side walls, opposite end walls, and upper edges, each of said side walls having a first pair of fold lines which are vertically oriented and parallel with one another in generally equally spaced relationship to said opposite end walls, said first pair of fold lines extending from the bottom to said upper edges of said tray, a second pair of fold lines extending across said bottom of said tray and between and in general alignment with each of said first pair of fold lines, each of said side walls having a third pair of spaced fold lines extending upwardly and outwardly in opposite directions along said side walls toward said opposite end walls from adjacent said bottom and proximate to said first fold lines to said upper edges of said tray at points spaced adjacent said opposite end walls, said tray being foldable about said second pair of fold lines with said side walls being simultaneously folded generally outwardly relative to said bottom about said first and third pairs of fold lines so as to form said closed configuration of said foldable box wherein the absorbent material is enclosed with said end walls are in overlying relationship with one another.
A transportable and disposable container for housing absorbent material comprising a foldable box which is convertible from a closed configuration to an open tray having upstanding and opposing side and end walls and a bottom wall, said opposing end walls being in overlapping relationship when said foldable box is in a closed configuration, said opposing side walls and said bottom wall being integrally formed from a sheet of material and being joined along lines of intersection therebetween, each of said opposing side walls and said bottom wall having foldable sections, said sections of each of said side walls including a generally central section and a first pair of outer sections, each of said central sections being foldable outwardly with respect to said first outer sections as said tray if folded into said closed configuration, and said first pair of outer sections being generally parallel with said central sections when said side walls are folded to form said closed configuration so that said central sections and said first pair of outer sections of each of said side walls will not be obstructed during folding by any absorbent material within said tray.
