Abstract
A flexible reclosable thermoformed thermoplastic container is disclosed which has a base with side walls and a peripheral shoulder extending from the side walls which has a downwardly depending rim. The cover of the container has peripheral edges with depending side walls and is preferably attached by an integral hinge to the base. The cover is adapted to close upon and cover the base. A locking tab with two opposed faces spaced to fit between the base rim and side walls is connected by an integral hinge to the cover. The locking tab of the cover may be rotated about the integral hinge and inserted between the side wall and rim wall of the base to close the container. Containers with depressions in the base or cover side walls to facilitate opening are also disclosed. Containers may have two locking tabs connected on opposite sides of the cover by integral hinges which permit the cover to be removed entirely from the container. By providing unclasped cover portions on such a container, a self-venting container may be formed. By providing a ridge on the base beneath the locking tab, the cover may be fixably attached to the base.
