US Patent 7891514 Easy open air-tight sealed food container

A food and liquid container is disclosed having a base and lid and providing for an air-tight seal between the base and lid when they are attached to each other. The seal is achieved at several points which create two air-pockets. The securing portion associated with the base can be substantially J-shaped in cross section, while the securing portion of the lid can be substantially u-shaped in cross section. A first ridge on the J-shaped section abuts with a second ridge on the u-shaped section when the lid is attached to the base with the second ridge disposed above the first ridge. The lower outer end of the u-shaped section can be rounded and a lip can extend outward for easier gripping when removing the lid from the base.
