HIGH-STRENGTH GUSSETED LID FOR A FOOD CONTAINER

摘要

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 andslopes downward at a first acute angle from the cont inuous rim to the transitionregion. The transition region encompasses the ce ntral region, extends between the peripheral region and the central region and includes first and second trans ition portions. The first transition portion intersects the peripheral region and slopes upward at a second acute angle from the peripheral region to the second tran sition portion. The second transition portion intersects the central region and slo pes upward at a third acute angle from the first transition portion to the central regi on. The second acute angle is greater than the third acute angle. The transition region inc ludes a plurality of spaced gussets interrupting the first and second transition por tions.
