A sealed container includes a tub ( 14 ), a lid ( 11 ), a flexible seal ( 15 ) disposed between the tub and the lid, and one or more ribs ( 12 a- 12 b) disposed on an interior side of the lid ( 11 ) that place pressure on the flexible seal ( 15 ) at potential seal failure points when the lid ( 11 ) is attached. The one or more ribs provide additional force to the flexible seal at places on the flexible seal where peeling of the seal is most likely to originate. The function of the rib is to restrain the film under pressurized conditions, but under normal conditions the rib may not contact the flexible seal. |
