Abstract

Method and apparatus for sealing containers. The apparatus includes a slideable carrier closure member in the form of a plate and a closure member that is retained in a recess in the face of the carrier closure member. The two closure members are guided between an open position and a closed position. In the open position the carrier closure member is removed to one side of the opening of a first container and in the closed position the closure member is aligned for sealing the container. The apparatus permits two containers to be joined together, equipment inside one container to be transferred to the other container and the containers to be thereafter separated while continuously maintaining the containers and the equipment sealed from the atmosphere.
