This is the case, for example, if there are still product residues in the dosing element and / or a pulverulent product that tends to form dust is dosed. Contamination of the operator by contact with the skin, mucous membrane or respiratory tract and any associated health hazards can therefore not be ruled out.

  • From the EP 1 708 941 B1 is a device for the contamination-avoiding emptying or filling of flexible bulk containers known. This sets a film tube as a link between a container to be emptied and a connection hose or an inlet opening. After the filling or emptying process, this film tube is tied together with the flexible container and / or the filled container, separated and disposed of the contaminated film tube.
  • the aforementioned devices have several disadvantages. Although the unintentional discharge of contents is prevented as far as possible in all devices and thus largely reduces the contamination of the environment and the operator, but the contents is in all proposed devices during the transfer or filling in contact with the filling and / or dosing , In sensitive areas, therefore, after the use of such devices, a cleaning and / or decontamination of the entire filling or metering device is necessary. An appropriate cleaning is associated with high time and cost and pulls a number of controls after the Be Glall- or metering device is used again.

It is further provided that the inlet opening, the inside of the Wall and the slot-shaped outlet opening are covered with the film-shaped material.
  • bag-shaped folds could arise in the film-shaped material as a result of the movements in the area of the outlet opening, and dosing goods could be enclosed in these folds. This could lead to the outlet of the metering element is no longer satisfactorily closed and leaks when one of these pockets forms in the slot-shaped outlet opening. Furthermore, it could also destroy the film-shaped material and thus repealed its protective effect.
  • Object of the present invention is therefore to provide a metering device of the aforementioned type, which has the highest reliability and the greatest possible safety concerning the contamination of the environment.
  • the metering device comprises a container for metered product with an outlet nozzle and a metering element adjoining the outlet nozzle.
