- 1. A disposable device for use as a litter box, comprising:
- a blank made of disposable flat material scored and cut in a predetermined pattern to form a receptacle section having a generally rectangular base and upstanding opposing side walls and opposing end walls;
- a top closure section including at least two opposing end panels pivotally connected to the opposing end walls of said base and opposing side panels pivotally connected to opposing sidewalls of said base, said end panels and side panels connected along a juncture and, actuatable between a closed position overlying the base and an upright open position wherein the side and end panels are upright permitting access to the receptacle section; and
- collapsible corner means at the juncture of the side and end panels operable to pivot inwardly to maintain and lock the side and end panels in the upright open position.
- 2. The device claimed in claim 1 wherein said collapsible corner means comprises straight line scoring provided on adjacent end and side panel extending from an upper edge of each panel downwardly to a point where they converge at the juncture of the end panel and side panel at a point spaced upwardly from the pivotal connection of said side and end panels to said side and end walls, defining two triangularly shaped, bendable sections which fold inwardly to lock the side and end panels in an open position.
- 3. The device as claimed in claim 1 wherein said side panels and end panels are connected to one another and are configured so that one side panel, when folded inwardly, forms end pockets with the end panels for receiving the free outer longitudinal edge of said side panel which includes at least two tabs, and means defining slotted openings in each pocket thus formed in a fold line connecting the one side panel and end panels and locking means comprising the tabs on the other said side panels engageable in the slotted opening to lock the side panels in the fully collapsed, or closed, position of the side panels and end panels.
- 4. The device as claimed in claim 1 wherein the tabs are bevelled to function as a pilot portion when reclosing the panels to the fully collapsed or closed and locked position.
- 5. The device as claimed in claim 1 including arcuate cutouts in the end panels to provide easy access to the receptacle section when the side panels and end panels are in an erect position.
