Abstract:
An aseptic molding process of a container starting from a parison (20) made of a thermoplastic material, comprising steps of:
blowing a first fluid into the parison (20) located in a mould (10);
introducing the first fluid into the compensating chamber (14) of the mould (10) through an inlet (15);
evacuating the first fluid from the molded container;
evacuating the first fluid from the compensating chamber (14) through an outlet (16) fashioned therein;
sterilising the compensating chamber (14) by supplying to the inlet (15) a second fluid containing a sterilising agent and evacuating the second fluid from the outlet (16) of the compensating chamber (14).
