The container includes a base and a detachable cover. To releasably attach the base and cover, the base includes a first closure portion and the cover includes an engagable second closure portion. In one aspect, the first and second closure portions are configured for engagement in both a fully engaged position and an intermediately engaged position. In the intermediately engaged position, the container can be further configured to vent steam during, for example, microwaving. In another aspect, the container including the first and second closure portions can be configured for simplified engagement of the base and cover, preferably by enabling engagement via a downward push applied to the center of the cover. In yet another aspect, the first and second closure portions can be configured with diverging flanges that simplify detachment of the base and cover.
