Filling Device for Transferring Flowable Process Material Between a First and a Second Container in a Manner Protected Against Contamination

A transfer device for contamination-protected transfer of flowable process material between a first container and a second container, comprising:

• a) a guide tube having an axial passage for the flow of the process material, which has a connection means at one end and terminates with a tube edge at the other end;
• b) a transfer unit opening into the guide tube, which transfer unit permits engagement in the guide tube and on which at least one peelable useful section provided with a first crimp is stored from a tubular liner supply;
• c) a first tensioner with the temporary function to fix in a sealed manner:
• ca) a residual end of a liner remnant coming from a previous transfer operation, forming a bag shape, is closed at the other end with a second crimp;
• or
• cb) a free open end of a new liner piece leading into the second container (B) as a bag-shaped inner liner;
• d) a second tensioner, arranged circularly on the guide tube and concentric to the first tensioner, with the temporary function to fix in a sealed manner:
• da) the residual end;
• or
• db) the free end of the new liner piece;
• and
• e) a pressing unit which can be moved axially in accordance with the longitudinal extension of the guide tube on a lifting linkage and comprises an axial passage for temporarily receiving the liner remnant and/or the new liner piece internally, and a seal which has the temporary function, to fix in a sealed manner solely the residual end resting against the tube edge or said residual end together with the free end of the new liner piece resting thereon or solely the free end of the new liner piece resting against the tube edge, wherein
• f) the pressing unit has a base part firmly connected to the lifting linkage and a pressing part elastically supported on the base part by means of a spring and having the seal arranged thereon.
