1. In a combined disposable box and sanitary station tray for pets, wherein said combination is formed from a single sheet of foldable material, said disposable box having a first half and a second half, each half having a bottom portion, an endwall and, a pair of sidewall portions bracketing its said respective endwall, and a connecting portion having a connecting bottom portion and pair of connecting sidewall portions there-in-between said first half land said second half, there being creases to facilitate folding between said connecting bottom portion and said pair of connecting sidewall portions and each said adjacent bottom portion and each said adjacent sidewall portion of said first and second halves, respectively;

  • said box initially defining a closed container with said sidewall portions and said endwall of said second half inter-laid within said sidewall portions and said endwall of said first half when said first and second halves are folded together to form a box; and

    forming a flat open sanitary station tray for pets with continuous surrounding upright side walls and end walls when said first and second halves of said box are folded open with their respective bottom portions and said connecting bottom portion in substantially co-planar relationship to one another, wherein the improvement comprises;

    each of said sidewalls of said first half having a tab extending from it, said tab for use in securing and locking said box;

    each of said connecting sidewall portions having a single inwardly folding diagonal crease extending from its top edge to its bottom edge and a pair of vertical creases extending from its top edge to its bottom edge, each said vertical crease being adjacent to one of said sidewalls of said first half or said second half, said vertical crease which is adjacent to said first half being outwardly folding, and said vertical crease which is adjacent to said second half being inwardly folding; and

    each of said sidewall portions of said second half having an inwardly folding diagonal crease extending from its top edge to its bottom edge;

    whereby after said box is opened to form a tray, and then re-closed to form a box with said second half inter-laying within said first half, said connecting sidewall portions and said two sidewalls of said second half all fold inwardly at their said respective inwardly folding diagonal creases and inwardly folding vertical creases to allow such inter-laying;

    nesting; and

    whereby further, a pair of slots is simultaneously formed on each side between each said inwardly folding diagonal sidewall crease of said second half and each said inwardly folding vertical crease between said second half sidewall and said connecting sidewall portion, thus allowing said tabs carried by said first half sidewalls to be inserted into said slots so formed between said creases and said second half sidewalls to thereby secure said tabs and lock said box closed, whereby said box is then ready for disposal or carrying.
