Abstract
A container including a combination of a bowl and a selectively detachable lid is disclosed. The bowl is a unitary structure including an upwardly projecting wall having a peripherally extending substantially U-shaped sealing lip. The selectively detachable lid is also a unitary structure including a body having a peripheral sealing lip which mates with the sealing lip of the bowl and at least one laterally extending tab member to assist in removing the lid from the bowl. Both the bowl and lid portions are preferably made from a resilient polymeric material suitable for both freezing and microwave reheating.

A lid for a container, said lid comprising:
- a body and a peripheral sealing lip extending from said body;
- and a substantially triangular shaped rigid tab member integrally extending from said sealing lip including a floor and a peripheral edge, said floor including a plurality of spaced apart upstanding ribs including a first rib disposed along a longitudinal center line and at least one other rib extending angularly away from said longitudinal center line.
A microwavable container comprising:
- a bowl including a bottom, a continuous side wall extending upwardly from said bottom and an L-shaped lip extending from said side wall;
- and
- a selectively detachable lid including a body having a peripheral sealing lip and a rigid tab member extending from said sealing lip;
- said tab member including a floor having a plurality of upstanding ribs including a first rib disposed along a longitudinal center line including a first edge extending at an angle of between about 3.degree. to about 7.degree. from said longitudinal center line and a second edge extending at an angle of between about -3.degree. to about -7.degree. from said longitudinal center line, a second rib including a first edge extending at an angle of between about 8.degree. to about 12.degree. from said longitudinal center line and a second edge extending at an angle of between about 20.degree. to 40.degree. from said longitudinal center line, and a third rib including a first edge extending at an angle of between about -8.degree. to about -12.degree. from said longitudinal center line and a second edge extending at an angle of between about -20.degree. to -40.degree. from said longitudinal center line.
