Abstract:
1. A thin walled tray for a foodstuff strengthened for supporting compressive loads when stacked, the tray comprising: a bottom wall having four corners; a sidewall extending about and upstanding from the bottom wall, the sidewall having an upper periphery, four corners and sidewall segments extending between adjacent pairs of the corners, each of the sidewall segments having at least one continuous, protruding rib configured to redirect vertical compressive forces from an intermediate portion of the sidewall segment to the adjacent corners, the rib having a vertex portion in the intermediate portion of the sidewall and inclined portions extending therefrom at a downward inclination toward the bottom wall and the respective adjacent corner; and depressions in opposing sidewall segments creating inwardly curved recessed portions of the opposing sidewall segments with respect to adjacent portions thereof that extend from the sidewall segments to the bottom wall so that the bottom wall has a waisted configuration wherein the smallest width of the bottom wall at the waisted configuration between the two opposite depressions is less than the width of the bottom wall between adjacent portions thereof, the depressions being located within the intermediate portion of the sidewall and generally aligned with the vertex portion of the rib so that the vertex portion of the rib is aligned over and overhangs the recessed portions of the opposing sidewall segments.
