Abstract
The present invention relates to a food container assembly comprising a base and a lid wherein the base and the lid are structurally identical in one of the embodiments. The base and the lid include inter-cooperating sealing areas in the form of ridges and mating grooves. The base and the lid can be joined via a first hinge/latch combination in a mutually hingeable relationship along a pair of corresponding sides, and in addition, can be mutually secured along an opposing pair of corresponding sides via a second hinge/latch combination. According to one embodiment of the invention, the container base includes a bottom wall; a sidewall; and a peripheral rim having a ridge portion, a groove portion, a hinge flap and a locking area; wherein the container base is adapted for engagement and latching with another identical container base disposed in an inverted and superjacent relationship therewith.
