ABSTRACT:
A foldable box includes six substantially rectangular plastic sides which are connected to each other by live hinges so that the sides may be folded flat or opened to a substantially hexagonal configuration. A substantially hexagonal plastic bottom is connected to the bottom edge of one of the sides by a live hinge and a substantially hexagonal plastic top is connected to the top edge of one of the sides by a live hinge. An inner flange extends substantially orthogonally from the bottom edges of at least two of the sides other than the one to which the plastic bottom is attached for supporting the plastic bottom when the box is assembled by folding. An outer extending flange is provided on at least two edges of the plastic top to support it when the box is folded closed. A removable substantially hexagonal plastic shelf is preferably provided and inner surfaces of at least two sides are provided with interior flanges to support the shelf. According to a presently preferred embodiment, the box is made from a molded plastic blank which is ultrasonically welded.
