METHOD FOR MOULDING AND STERILIZING A CONTAINER MADE OF PLASTIC MATERIAL, DEVICE FOR MOULDING AND STERILIZING A CONTAINER MADE OF PLASTIC MATERIAL AND MOULDING AND STERILIZING MACHINE

摘要

Method for moulding and sterilizing a container made of plastic material, comprising the steps of: opening a mould (4) made of metal material; inserting a parison (3) into the mould (4); closing the mould (4); inserting a stretching rod (23) made of metal material into the parison (3); blowing and stretching the parison (3) in such a manner as to obtain the container; keeping the stretching rod (23) inside the moulded container; evacuating the blowing fluid; applying a voltage difference between the stretching rod (23) and the closed mould (4) in such a manner as to transform the fluid at atmospheric pressure remaining inside the moulded container into plasma.
