Abstract: An assembly created of multiple layers of semi-rigid trays. The size of the surface area of the assembly can be increased by use of side interlocking elements on each tray. These side interlocking elements do not consist of extra parts which require fairly dexterous manipulation, sometimes in the center of a large surface area. Additionally, these side interlocking elements are rotation symmetrical and self-centering, all of which enhances the potential for automated handling. The tray layers are separated by containers which are held by formations in the upper and lower surfaces of each tray. The formations in upper surface of the lower tray layer and the lower surface of the upper tray layer cooperate to hold the containers such that the containers touch each other along their sides and are maintained in a substantially vertical position, which is particularly suited for containers prone to bulging and creeping.
