  • the first part of the filling device 33 comprises a nozzle tube 34, which is arranged concentrically to the sprocket 8 and runs synchronously with it, the nozzles of which are directed precisely at the mouths 2c of the bottles 2 moved past by the conveyor chain 15.

The pressure difference between the inner and outer wall is therefore only small and is not sufficient to cause permanent deformation of the bottles 2.

  • the sprocket 10 then deflects 180 degrees while passing through the vertical normal position of the bottles 2. Then the bottles take again their horizontal emptying position and are transported vertically downwards to another sprocket 11. Liquid disinfectant can slowly leak out of bottles 2 again.
  • the conveyor chain 15 with the bottles 2 is deflected by 90 degrees by the chain wheel 11), the bottles being partially immersed in the immersion bath 4 and being brought into their upright normal position.
  • the guide rails 13, 14 are arranged here in such a way that the bottle mouth 2a remains above the liquid level S in the immersion bath 4, so that no more disinfectant liquid can run into the bottles 2 and the pressure on the bottles does not become too great.

  • a permanent deformation of the bottles 2 can no longer be brought about by the negative pressure that occurs during the complete emptying, since the bottles have been emptied at least half by the three preceding areas with a horizontal emptying position. Even extremely thin, material-saving and light disposable bottles cannot be deformed or damaged when emptied.
  • the bottles 2 then run with the mouth facing downward from the left end face of the housing 3 in the horizontal direction to the right end face of the housing 3, the first consisting of a plurality of nozzles and / or still pipes Pass spray station 18.
  • the disinfectant still adhering to the outside of the bottles 2 is rinsed off by sterile water.
  • the bottles are then turned through 180 degrees and in turn run essentially horizontally back to the left end face of the housing 2, where the second spray station 19 for rinsing the inside of the bottle with sterile water is arranged in the area of a chain wheel.

Abstract

L'invention concerne un procédé de traitement, en particulier, de stérilisation de bouteilles en matière plastique (2), selon lequel lesdites bouteilles sont remplies, au moins de moitié, d'un liquide de bain, avant d'être complètement immergées dans un bain (4) renfermant le liquide, et sont amenées, après avoir été retirées du bain, en une position de vidage approximativement horizontale, jusqu'à ce qu'au moins la moitié du liquide contenu dans les bouteilles soit écoulée, après quoi les bouteilles sont pivotées, goulots vers le bas, de manière à permettre l'écoulement des restes de liquide. De cette façon, des bouteilles en matière plastique, même délicates, peuvent être stérilisées avec une fiabilité microbiologique élevée et sans entraîner des dommages et déformations permanents.
