Abstract
A food serving tray, preferably of polystyrene foam, is provided having a base and bounding side walls. The base is formed with at least two bottom walls and at least one partition interposed therebetween. To provide enhanced stability and rigidity to the tray, protrusions, preferably step-shaped, are formed in the side walls located between the crests of the partitions and the top edges of the side walls. The protrusions provide changes in direction in the side walls which enhance the strength and rigidity of the tray. In addition, the bottom walls may be dished concavely so as to have portions extend upwardly. Under loading, the dished bottom walls become flattened and bi-axially stressed to further enhance the overall strength and stability of the tray.
