Patent Images
1. A paperboard plate comprising:
- a base having a substantially smooth flat surface having an overall base length and an overall base width;
a plurality of side walls extending upwardly from the base, each side wall having a substantially straight upper edge at a height from the base, the height being less than about 0.20 times the base length; and
a plurality of corner walls extending upwardly from the base, each corner wall disposed between a pair of adjacent side walls and having a substantially straight upper edge at the height from the base,the upper edge of each side wall having a side wall upper edge length, andthe upper edge of each corner wall having a corner wall upper edge length less than each side wall length,wherein dimensions of the paperboard plate are selected to provide a rigidity measured by the industry standard Foodservice Packaging Institute rigidity system to be greater than about 450 grams.
