ABSTRACT:
A re-usable compact self-containable collapsible container comprising a substantially rectangular base and four substantially rectangular walls having parallel sides and parallel ends. The sides and ends are foldably joined to a perimeter of the base opposite each other respectively. Each side is foldably joined end-to-end with adjacent ends and each end is foldably joined end-to-end with adjacent sides. Each side is foldably divided into three segments along lines extending approximately a 45 degree angle from a corner toward approximately a center of the side. The three segments comprise a center segment foldably joined to two outer segments where an outer segment base length is approximately equal to one-half of a center segment base length. The sides and ends cooperatively form an open mouth of the container substantially co-extensive with the perimeter of the base when the container is in an expanded position. A first side of the sides is foldable inwardly toward a second side of the sides, the first side of the sides being positionable over the second side of the sides with both first and second sides being positionable over the base. The ends are foldable inwardly toward each other over the sides and over the base without overlapping each other. Each side and end is substantially parallel to each other side and end and the base and the sides and ends are substantially contained within the perimeter of the base when the container is in a collapsed position.
