Abstract
A food storage container 10 includes a base 12 and lid 14. The base 12 has a sealing flange 22, and the lid 14 has a sealing lip 32 which seals against the sealing flange 22 as with a suction cup. The lid 14 may include resilient deformable sections 46, 50, to aid in maintaining reduced pressure within the container. The lid 14 may include latch prongs 54 to mechanically retain the lid 14 in position. The latch prongs 54 may be designed to automatically release during heating of the food, permitting venting. The sealing lip 32 may include seal spacers 60 which permit air to enter the food storage container 10 during serving of hot food to avoid creation of reduced pressure in the container. The seal spacers 60 do not interfere with normal creation of a seal when desired.
