Abstract
A litter box (1) including an outer front side wall (3), an outer rear side wall (4), an outer left side wall (5), a cover member (8), and an outer right side wall (6). The litter box (1) is formed from a single integral cardboard sheet (2) which, when folded in an appropriate fashion, results in an enclosed, disposable litterbox. The box (1) may be shipped with a supply of litter enclosed, and may be shipped and stored in a rectangular package of approximately 2 inches in height.
Claims1
A method of constructing a box, comprising the steps of:
- (a) forming a sheet of a relatively stiff, foldable material into a substantially rectangular planform;
- (b) designating a substantially rectangular perimeter on the sheet so as to delineate a rectangular bottom member having an integrally adjacent front end flap, an integrally adjacent rear end flap, an integrally adjacent right side flap, an integrally adjacent left side flap, a roof panel, the roof panel being integrally formed between the right side flap and the left side flap, the roof panel being compatibly dimensioned so as to fit snugly along the front end flap and the rear end flap, the roof panel residing in at least one plane displaced somewhat above the bottom member, the front end flap, the rear end flap, the right side flap and the left side flap each possessing a substantially rectangular sheet-like extension, the sheetlike extensions serving as corner reinforcing members for the box, the sheet-like extensions adjacent to the left side flap and the right side flap being formed so as to have end tabs such that, after the sheet-like extensions are folded into the box so as to form the corner reinforcement members, the end tabs may be inserted into mating orifices within the roof panels so as to be parallel to the front end flap and the rear end flap, thereby securing the roof panel above the bottom member of the box;
- (c) folding the front end flap, the rear end flap, the right side flap, and the left side flap upwardly so as to form a four sided container having four corners, the corners being defined by an intersection of adjacent, abutting flaps, the roof panel being foldably inserted into the box after the front end flap, the rear end flap, the left side panel and the right side panel are folded inwardly so as to be enclosed within a volume defined by the crease zones and the bottom member;
- (d) securing each of the corners at the intersection so as to form a substantially rigid, permanently shaped container.
