Abstract
The present invention is a container for food. The container has a lid and a base which form a series of three self-reinforcing seals when mated. A protrusion on the lid reinforces the triple seal formed between the lid and base. The protrusion applies a force to the base, locking the lid and base together. The third seal has the largest surface area and acts as a first line of defense against food leakage out of the container and a last line of defense against the entry of contaminants into the container.
