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.

[ What is claimed is:] [1.] A stackable tray for stacking in parallel with similar trays, comprising:a tray bottom having two opposite sides; andtwo side walls respectively joined to the opposite sides of the tray bottom, each side wall having a top portion with an inner channel wall and an outer channel wall that together define a top channel, each side wall further having a bottom portion with an inner channel wall and an outer channel wall that together define a bottom channel, the top channel and the bottom channel extending in parallel directions,the bottom channel of each side wall being configured to slidably receive a pair of adjacent outer channel walls of top portions of two similar trays on which the stackable tray may be stacked in parallel, and the top channel of each side wall being configured to slidably receive a pair of adjacent outer channel walls of bottom portions of two similar trays which may be stacked upon the stackable tray in parallel.
