Abstract: A container has an assembled condition in which it is used for transport or storage of goods and a disassembled condition in which the elements of the container are collected into an integral unit. The container comprises top and bottom members. Columnar members are received in the top and bottom members when the case is in the assembled condition. The columnar members have at least a pair of peripherally spaced slots extending along the columnar members. Each of a plurality of side members are inserted in a slot of a columnar member in one corner of the top and bottom members and in a slot in a columnar member positioned in an adjacent corner to form one of the sides of the container. A locking device consisting of a pair of latch members releasably retains the columnar members in the top and bottom members. For this purpose, the pair of latch members engage a pair of mounting rod mounted across the interior of the columnar members.
