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.

An integral packaging tray comprising a generally rectangular bottom and sidewalls extending upwardly from edges of said bottom, said sidewalls being of substantially the same height and being integrally connected around the periphery of said bottom, said bottom containing at least one integrally formed reinforcing rib projecting upwardly therefrom and extending along said bottom from a substantially centerline portion of said bottom defined between two opposing sidewalls toward said two opposing sidewalls, said rib having a maximum cross-sectional dimension at said substantially centerline portion and tapering to a minimum cross-sectional dimension at its termination with a uniformly reducing cross-sectional dimension as it approaches said two opposing sidewalls.
