  • a station is provided in which the bottles are sterilized.
  • a difficulty here is usually that the bottles must be sterilized not only externally, but also on their inside, since this requires the corresponding electron beam through the relatively small bottle opening into the bottle interior and there must be distributed as evenly as possible.
  • the proposed devices have the disadvantage that the electron beams have to walk through a relatively large path length in the interior of the bottle, wherein they are reflected several times on their way.
  • the electron beams must therefore have a relatively high range, so that they completely migrate the intended path.

  • the beam in the region of the focus has a small surface area and thus can easily pass through the bottleneck.
  • the beam fanned beyond the focus point again and distributed throughout the bottle interior, without having been reflected once, ie on a direct path.
  • a diffuse electron cloud By focusing forms at the end of the range of electron beams a diffuse electron cloud, which has contact with the inside of the container.
