A container consisting of cooperating top and bottom trays. Each tray has opposed upstanding end walls and opposed upstanding side walls. The height of the end walls of each tray are greater than the height of the side walls of the same tray. In order to assemble the two trays together to form a container, the two trays are inverted relative to each other so that one tray forms a top and the other tray forms a bottom. The two inverted trays are rotated 90.degree. so that the taller end walls of one tray cooperates and telescopes over the shorter side walls of the other tray to form a container.
