In a paperboard food container, especially the clamshell type used in the fast food industry, a releasably interlocking means between the container and a lid. The interlocking means includes a slot formed in the container which not only leaves a continuous, coplanar shoulder around the circumference of the container which allows complete sealing with a lid structure, but additionally provides a tab which extends above the slot, allowing the lid structure to have either a flange extending under the container tab or, in addition to the flange, a tab inserting into the slot.
