Releasable connecting device between internal spaces of two containers

摘要

The connecting device is fitted between containers with at least one wall (1,2) adjacent to each other. There are closable apertures (3) in each container, and a connecting piece (10) between the apertures. The connecting piece is in the form of a tubular support, closed on one side, with its closed end projecting into the aperture of the first container. Together with a spring (7), this forms a valve with first (6) and second (6) valve seats. The first valve seat can be opened from inside the container by the force of the spring. The second can be opened from the free end of the connecting piece, which has passage zones (13) open at the side at both ends.
