ABSTRACT:
A pair of side walls for supporting a tray in a stacked configuration and a stackable tray having a tray bottom and two such side walls joined to the tray bottom at opposite sides, each side wall having a channel along its top edge and a channel along its bottom edge and so configured that when two side walls of two such trays and their bottom edges are placed parallel and adjacent to each other, a portion of each such bottom edge can be received in a channel in a top edge of a side wall of a third tray of the invention. In the preferred embodiments shown, the tray bottom has egg holding cells. The trays can be stacked and unstacked by sliding trays at the top of a stack. The side walls have openings and supporting ribs providing support for weight carried by the side walls. The side walls are joined to be substantially parallel when the tray is loaded. The tray bottom is joined to the side walls with fillets that minimize the flexural deflection between tray bottom and side walls. The side walls are joined to the tray bottom so that a plane of a side wall forms a precompensation angle with a plane of the tray bottom of about 3.degree. off of perpendicular.
