ABSTRACT:
A lid for a plastic food container includes a continuous body portion and a continuous rim encompassing and projecting laterally outwardly from the body portion. The body portion includes a peripheral region, a transition region, and a central region. The peripheral region encompasses the transition region and the central region, extends between the continuous rim and the transition region, and slopes downward at a first acute angle from the continuous rim to the transition region. The transition region encompasses the central region, extends between the peripheral region and the central region, and includes first and second transition portions. The first transition portion intersects the peripheral region and slopes upward at a second acute angle from the peripheral region to the second transition portion. The second transition portion intersects the central region and slopes upward at a third acute angle from the first transition portion to the central region. The second acute angle is greater than the third acute angle. The transition region includes a plurality of spaced gussets interrupting the first and second transition portions.
