<p>A stackable mushroom tray (10) having a plurality of curved ribs (20) that extend near but do not contact sidewalls (24) of the tray. Open corner receptacles (14) are formed at each corner of the tray to receive a spacer (12). Support feet (42) are formed within each corner of the tray to receive a top surface of the spacer. Raised corrugations (18) are placed between the curved ribs (20) with a plurality of holes (16) between the raised corrugations (18). A lip (26) is formed around the perimeter of the sidewalls (24). The tray is preferably made of a composite material such as plastic and fibrous material that can be easily molded. The structure and configuration of the tray permit a relatively thin walled tray to be used, yet is extremely rigid and can be stacked easily while maintaining lateral stability.</p> |
