Abstract
An optimized tray for case-ready meat products is disclosed. The tray comprises a base, a plurality of sidewalls connected at a plurality of corners, a flange extending from an upper edge of each sidewall, and a plurality of substantially vertical ribs extending from said sidewalls and spaced apart therealong. At least one of the sidewalls is bowed inwardly, and the flange along at least a partial length of the at least one bowed sidewall is varied in width. The ribs can also vary in thickness along at least a partial length of at least one of the sidewalls. The interaction of the at least one bowed sidewall, the varying flange width, and the varying rib thickness allows for optimization of tray resistance to vertical and horizontal stress without increasing the overall outer dimensions of the tray and without substantially decreasing the internal volume of the tray.
