ABSTRACT:
An annular flange extends radially from the rim around the open top of a container in a plane perpendicular to the axis of the container. The flange is integrally formed with the container and has a plurality of notches formed therein and extending radially inwardly from the outer edge of the flange. The flange has a planar top surface and tapered bottom surfaces forming a plurality of inverted inclined planes relative to the top surface, each extending from one of the notches to the next-adjacent notch in the same direction around the flange. A lid has a plurality of lock members formed thereon in the same angular relation as the notches of the container whereby each of the lock members is simultaneously passable through a corresponding one of the notches of the flange of the container. Each of the lock members comprises an arm supported by the lid and extending parallel to the lid in spaced relation below the lid in a manner whereby when the lid is positioned on the container with the lock members in alignment with the notches of the flange and such members are passed through the notches and the lid is turned, the arms of the lock members move into abutment with the bottom surfaces of the flange. If the lid is further turned, the arms securely seal the lid to the container via the flange.
