Abstract: A method for the contamination-preventing transferring bulk material between a container having a flexible opening and a connecting tube using a tubular film is placed around the connecting tube; the tubular film is tied beyond the connecting tube leaving a free end of the tubular film beyond the tying point; the flexible opening and the tubular film are connected; the tying points of the outlet and the tubular film are untied, and the bulk material transferred; the free end of the tubular film, is constricted and additional tubular film is pulled from a tubular film supply until clean tubular film is available beyond the connecting tube; the tubular film is closed at two points in the clean section and cut in two between them; additional tubular film is pulled from the tubular film supply, and tied at a tying point located at a distance from the cutting point.

Abstract: A liner emptying device and a liner filling device as well as methods using them for contamination-free filling and emptying of a liner. This contamination-free filling and emptying prevents any danger to the health of the people working with the packaged substances. Both the liner emptying device and the liner filling device are connected to the liner via a fastening device and the residual films sealing off the device can be removed via an access port, whereby the liner can be filled or emptied without contaminating the surroundings.

Abstract: A method for operating a package emptying station having a work station, in which an emptying step is performed, an inlet via which the package to be emptied is inserted into the work station, an outlet via which the emptied package is ejected, and a product outlet through which the emptied contents of the package is discharged. Continuous tubular film packs are provided both at the inlet and also at the package outlet which seal off the inlet and the outlet and encase the package to be emptied or the emptied package during the insertion or corresponding ejection of the package. The film is sealed off and severed between individual packages such that the interior and the exterior do not come into contact. In this manner, both contamination of the package contents by environmental substances and also any contamination of the environment by the package contents can be avoided.

Endless tubular film packs are provided both at the inlet and also at the package outlet which seal off the inlet and the outlet and encase the package to be emptied or the emptied package during the insertion or corresponding ejection of the package. The film is sealed off and severed between individual packages such that the interior and the exterior do not come into contact.

Abstract: Trickling safeguard for a filling station used to fill containers with bulk material, the filling station having a fill tube through which the bulk material flows into the container. The safeguard includes a two-part flap whose dimensions at least match those of the interior cross section of the fill tube and is arranged transverse to the length of the fill tube at the end thereof. The flap parts are pivotable about a shaft so as to lie in the direction of the bulk material stream.
