METHOD AND DEVICE FOR STERILIZING AND FILLING PACKING CONTAINERS

摘要

The invention relates to a method for sterilizing, filing and sealing one-side opening packing container (1), wherein the packing container (1) is initially exposed to a sterilizing agent in a steady flow conveyor in a processing line comprising several processing stations. Said sterilizing agent is removed afterwards with sterile hot air. The packing containers (1) are then filled with a sterile fluid product and closed with a sterile seal. In order to carry out sterilization and sterile filling and sealing without requiring a costly sterile area and using simple technical means, the invention foresees that during sterilization the corresponding liquid fluid be pressure filled through the middle of the opening (17) of each packing container (1) in the relevant processing station up to the area between the middle and the bottom of the packing container, eventually up to its bottom, that said fluid be diverted towards the opening (17) inside the packing container (1) and squeezed out in such a way that a first part (36) of the outflowing liquid is suctioned from the area surrounding the opening (17) and a second part (35) is allowed to come out in the area (32) surrounding the opening (17) of the packing container (1).
