Abstract: A disposable cat litter box comprising a single sheet of stiff paperboard which is folded and perforated for assembly into an open top, generally rectangular cat litter box is disclosed. The box is prepackaged with cat litter and may be assembled to form a cat litter box. The box preferably includes a horizontally extending bottom attached to upwardly extending side and end walls. The side and end walls having foldable portions which may be folded over and sealed to define a substantially rectangular closed box. For use, the upper portions of the side and end walls are unfolded and positioned substantially perpendicular to the bottom portion. End flaps on the side and end walls may be folded inwardly forming a rigid perimeter defining an open, generally rectangular box. After use, the side and end walls may be collapsed and folded over to enclose the cat litter for disposal.

Abstract: A collapsible, foldable travel crib is disclosed. The illustrated and preferred embodiment is comprised of a single sheet of stiff board which is folded and perforated in a manner to be described to assemble into an open top, generally rectangular crib. It incorporates a set of edge stiffeners having a U-shaped cross section. In the assembled state, the stiffeners are fastened along the top edge to define a straight top edge gaining reinforcing from the stiffeners. In the folded state, the stiffeners are placed along the edge to close the apparatus into a folded, flat body which is easily carried.

Abstract: An improved carton construction is disclosed. In the illustrated embodiment, it utilizes a top closure which folds over the top of the assembled carton, therebeing a matching closure on the opposite side to define a central opening for ventilating the fruit. Each top closure has appended at each end a curved skirt which terminates in a protruding tab. The tab inserts into a half circle opening, commonly called a half-thumb hole which is cut with an L-shaped cut, thereby securing the pair of top closures above a multiple thickness shoulder which gives strength to the end wall of the box for stacking.
