  • the second coupling closure 110 changes its external shape when it is opened or closed, it is advantageous if the tube element 102 is connected to a base body or container, which is essentially non-moving, on the second coupling closure 110.
  • This connection 116 may be, for example, commercially available Triclamp compounds.

  • Triclamp connection 116 it has been found to be particularly user-friendly if the connection 116 is of a reversible nature, so that a multiple or double closure 120 can be assembled only when necessary, for example in the case of very high purity requirements during a transfer process.
  • Suitable Triclamp compounds for example, sit down as in FIG. 19 shown, from two Triclamp components 132 and 134, one of which, 132, fixed to eg the container or the body of the coupling closure, for example via a welded joint, is connected.

  • the second coupling closure 110 ' likewise has a closing flap which can be firmly and sealingly connected to the closing flap of the second coupling closure 110, in which case both closing flaps can be pivoted via an actuating device 118 from a closed position into an open position.
  • Such bulk material residues can be removed, for example, via a suction device (not shown) by applying a vacuum prior to decoupling the docking device 104 from the described interior.
  • this interior space or the partial internal spaces of the hose elements 120 and 120 'obtained after closing the docking device 104 can first be cleaned with a cleaning agent, in particular a cleaning liquid, and then dried or evacuated.
  • the hose element 120 'and / or the coupling closure 110' should preferably form a conical or funnel-shaped transition or shape in the direction of the opening of this coupling closure.
  • a particularly high degree of safety can be achieved in that the hose elements 120 and 120 'are at least partially transparent. After completion of the Um Glallvorgangs the hose elements 120 and 120 'can be detached from the walls of the vessels or coupling closures and are available for further use with other dockable vessels.
