Abstract
The disclosure relates to a method and an apparatus for producing a sterile packaging container from a thermoplastic blank or preform which, during stepwise displacement between different processing stations (A-H), is subjected to a first heating to a temperature suitable for a subsequent sterilization with the aid of a chemical sterilization agent in gas form. A subsequent, additional heating stage imparts to the blank the desired moulding temperature, whereafter the blank, after displacement to a blow moulding station, is blow moulded to the desired configuration with the aid of mould halves ( ) surrounding the blank. Hereafter, the blank is displaced to a filling station (E) in which it is filled with the desired contents in order thereafter finally to be sealed with the aid of a wafer ( ) and discharged out of the apparatus according to the present invention.
