Abstract:
1. A method for transferring bulk goods, without contamination, into or out of a container via a connection tube, comprising the steps of: positioning the container and the connection tube one above the other, arranging a hose film around the connection tube, so that it rests against an edge of the connection tube at an open end thereof so that it seals, tying the hose film at a tying point beyond the connection tube so that a free end of the hose film, which can be widened in the shape of a funnel, remains beyond the tying point, forming a clamping connection of opening of the container to the hose film so that a portion of the free end of the hose film remains beyond the clamping connection, untying the tying point, transferring the bulk goods, tying of the free end of the hose film remaining beyond the clamping point, pulling hose film out of a hose film supply until a region of clean hose film is available beyond the connection tube, sealing of the hose film at two adjacent sealing points in the region of clean hose film, cutting the hose film at a point between the two adjacent sealing points, one of the two sealing points remaining attached to hose film after said cutting, pulling of hose film out of the hose film supply and tying the same again at a new tying point that is at a distance from the sealing point remaining in the region of the cutting point, removing the sealing point remaining in the region of the cutting point and widening of the hose film between the cutting point and the new tying point to form a funnel shape.
