Definitions

  • the invention relates to a device for minimizing the oxygen content in containers to be filled and already formed by a blow molding process according to the feature configuration of the preamble of patent claim 1.
  • the mold When manufacturing highly sensitive products, for example in the form of special pharmaceuticals to meet international standards for aseptic packaging, the mold, when placed in the filling position, is under a so-called bottling sterile room (ASR), in which sterile air flows over the open filling opening of the containers and provides effective protection against the ingress of germs until, after completion of the filling operation, movable head jaws of the mold are closed to form the desired head closure of the container by a combined vacuum welding operation. Due to the sterile barrier it is prevented that after cutting the tube foreign matter can fall into the open filling opening before the form has reached the filling sterile room (ASR) and further prevents the sterile barrier during this process section and the unwanted access of germs to the filling opening.

  • the displacement medium is supplied both via the respective media supply channel as well as via the respective media transport channel, this can be displaced directly into the environment outside of the feed device from the container interior, together with the atmospheric oxygen to be displaced.
  • the above displacement results can be improved if another media channel, preferably designed as a media supply channel, in concentric arrangement to the wall of the Gudorns and this is comprehensively present, wherein the further media channel is chambered outwardly from another wall of the feeder. Additionally or alternatively, it may furthermore preferably be provided to provide the surrounding area of the respective container to be filled with a barrier medium at least partially by means of a further feed device. In this way, the oxygen content in the surrounding area of the respective container opening can also be reduced, which contributes to an improvement in the minimization result of oxygen content.
