ABSTRACT:
A stackable box of the type positionable in a stack with other boxes comprises a frame with walls formed of non-flowable moldable material having angular portions assembled to form outwardly extending corners. The frame is formed with a downwardly and inwardly extending lower portion and an upper portion. A horizontal base is located within the interior of the frame above the lower portion thereof. At least two walls of the frame are formed with a groove to receive a cover closing the box. An upwardly projecting web is formed at the upper portion of each wall adapted to extend toward the lower portion of the frame of the successive above-positioned box to form a locking connection therewith. The depth of the groove is sufficient to receive the cover as the latter is inserted into the frame in either flat or sloped position.
