This can then be removed by suitable devices and, for example, transferred from the gripping device 250 to an outlet star or a downstream container treatment machine, for example a capper. The filling element is then in the basic position again.
  • the filling elements and filling methods described do not need any separately provided relief paths, which means that the installation and cleaning effort can be considerably reduced. Since the relief paths are eliminated, there is also considerable process uncertainty that arises from the lack of monitoring of the cleaning and sterilization of the previously common relief paths.
  • the filling elements according to the invention can thus also be used for filling weakly acidic products which place increased microbiological demands on hygiene.
  • the processes described can be used for carbonated and still drinks as well as for products from the non-food sector.
