ABSTRACT:
Disclosed is a packing tray having an improved rib reinforcement. At least one tapered rib extends along the bottom of the tray from a longitudinal centerline portion toward opposing sidewalls. The rib cross-section progressively decreases from the centerline portion toward the terminating end of the rib. The tapered rib provides tray reinforcement where it is most needed while minimizing intrusion into available packaging volume.
