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.

What is claimed is: 1. A method of emptying containers having liners using a liner emptying device, which comprises: a base body having an opening and forming a chamber into which a container having a liner is emptied, a first fastening device for fastening the liner to the opening, a sealing flange for sealing the liner to the opening, a lever for raising and placing the sealing flange away from or onto the opening, an access port for providing access into the base body with a second fastening device for fastening a film bag or a continuous tubular film on the access port, and a connecting device for connection of the liner emptying device to a component of a treatment process, comprising the steps of: a) attaching a closed liner of a container to be emptied through the sealing flange to the first fastening device, at which a closed remainder of a liner of a previously emptied container is also attached, b) fastening a film bag to said access port, at which a film closing the access port is also attached, or a continuous tubular film to said access port, c) removing the closed remainder of the liner of the previously emptied container at the opening through the access port, d) placing the sealing flange so as to seal the liner to the opening, e) emptying the connected container into the liner emptying device, f) tying off the liner at two adjacent locations and cutting the liner between the two adjacent locations. 2. The method according to claim 1, comprising further the step of: subsequent to step b), removing the film closing the access port by twice tying off the film bag at two adjacent locations and then cutting the film bag between the tied-off locations. 3. The method according to claim 2, wherein the first fastening device for fastening the liner to the opening comprises an inner and an outer groove, further comprising the steps of: in step a), fastening the liner in the inner groove with an O-ring and, after step c), pushing the O ring fastening the liner onto the outer groove. 4. The method according to one of the claims 2, further comprising the step of: in step e), closing the access port with a cap. 5. The method according to one of the claims 2, wherein the second fastening device for fastening the film bag comprises an inner and an outer groove, further comprising the steps of: in step b), fastening the film bag in the inner groove of the second fastening device with an O-ring and, between step b) and c), pushing the O ring fastening the film bag onto the outer groove of the second fastening device. 6. The method according to claim 1, comprising further the step of: in step c), drawing the closed remainder through the access port into the film bag or the continuous tubular film and separating the closed remainder by tying off the film bag or the continuous tubular film at two adjacent locations and cutting the film bag or the continuous tubular film between the two adjacent locations. 7. The method according to claim 6, comprising further the step of: subsequent to step b), removing the film closing the access port by twice tying off the film bag at two adjacent locations and then cutting the film bag between the tied-off locations. 8. The method according to claim 6, wherein the first fastening device for fastening the liner to the opening comprises an inner and an outer groove, further comprising the steps of: in step a), fastening the liner in the inner groove with an O-ring and, after step c), pushing the O ring fastening the liner onto the outer groove. 9. The method according to one of the claims 6, further comprising the step of: in step e), closing the access port with a cap. 10. The method according to one of the claims 6, wherein the second fastening device for fastening the film bag comprises an inner and an outer groove, further comprising the steps of: in step b), fastening the film bag in the inner groove of the second fastening device with an O-ring and, between step b) and c), pushing the O ring fastening the film bag onto the outer groove of the second fastening device. 11. The method according to claim 1, wherein the first fastening device for fastening the liner to the opening comprises an inner and an outer groove, further comprising the steps of: in step a), fastening the liner in the inner groove with an O-ring and, after step c), pushing the O ring fastening the liner onto the outer groove. 12. The method according to one of the claims 11, further comprising the step of: in step e), closing the access port with a cap. 13. The method according to one of the claims 11, wherein the second fastening device for fastening the film bag comprises an inner and an outer groove, further comprising the steps of: in step b), fastening the film bag in the inner groove of the second fastening device with an O-ring and, between step b) and c), pushing the O ring fastening the film bag onto the outer groove of the second fastening device. 14. The method according to one of the claims 1, further comprising the step of: in step e), closing the access port with a cap. 15. The method according to one of the claims 14, wherein the second fastening device for fastening the film bag comprises an inner and an outer groove, further comprising the steps of: in step b), fastening the film bag in the inner groove of the second fastening device with an O-ring and, between step b) and c), pushing the O ring fastening the film bag onto the outer groove of the second fastening device. 16. The method according to one of the claims 1, wherein the second fastening device for fastening the film bag comprises an inner and an outer groove, further comprising the steps of: in step b), fastening the film bag in the inner groove of the second fastening device with an O-ring and, between step b) and c), pushing the O ring fastening the film bag onto the outer groove of the second fastening device.
