Abstract: A knock-down, stackable multipurpose container utilizes a pair of end members or panels having a number of slots or devices for slidably engaging various top, side, bottom and intermediate spacer members or panels. The top edge of the end members is provided with a raised portion which, in the embodiment described, defines a handle. The bottom edge of the end members is provided with a recess adapted to receive and engage the raised portion or handle of an identical multipurpose container. The bottom panel is adapted to cooperate with the bottom recess of the end member to maintain vertical alignment of the stacked containers.
