Abstract
The present invention relates to a food packaging cover for use with a compatible tray. The cover includes a top section, a wall section, a shoulder section interconnecting the top section and the wall section and a bottom peripheral edge formation designed to lockably engage the tray. The wall section is formed from a repeating pattern of furrows which enhance the strength of the cover. The interconnecting shoulder section is formed from triangular flats interspaced by gusset members to effect substantial uniform distribution to the wall section of a load placed on the top section.
