A food container comprises top and bottom members, with the bottom member including a lower base wall and an upwardly extending side wall. Spaced apart downwardly extending depressions are formed in the lower base wall, and each of these depressions has an inside wall surface spaced inwardly from the surrounding side wall. The inside wall surfaces of the depressions collectively define an outline, and the top member has a raised central portion the outline of which is substantially identical to but slightly smaller than the outline defined by the depressions. This relationship enables the raised central portion of the top lid member to interlockingly fit between the depressions when assembled food containers are stacked one above the other. The raised central portion of the top lid member has less height than the depressions which spaces the lower base wall from the raised central portion when assembled containers are stacked. As a result, open passageways are provided between the spaced apart depressions, the lower base wall of the bottom member and the raised central portion of the top member which may include vent openings therein.
A food container comprising a bottom member and a top lid member constructed and arranged to cover the bottom member when the members are assembled, the bottom member including a lower base wall and an upwardly extending side wall surrounding the base wall, a plurality of spaced apart downwardly extending depressions in the lower base wall, each of the depressions having an inside wall surface spaced inwardly from the surrounding side wall of the bottom member, the inside wall surfaces of the depressions in the lower base wall of the bottom member collectively defining an outline, the top lid member including a raised central portion having an outline substantially identical to but slightly smaller than the outline defined by the inside wall surfaces of the depressions whereby the raised central portion of the top lid member interlockingly fits between the inside wall surfaces of the depressions when assembled food containers are stacked one above the other, a depressed area in the raised central portion of the top lid member, a plurality of vent openings in the depressed area, and the raised central portion of the top lid member having less height than the depressions whereby the lower base wall of the bottom member is spaced from the raised central portion of the top lid member when assembled food containers are stacked one above the other thereby providing open passageways between the spaced apart depressions, the lower base wall of the bottom member and the raised central portion of the top lid member with the plurality of vent openings in the depressed area thereof.
