Abstract

Process involves extrusion of a closed end parison from a die with a sterile air supply for dilating the parison. A special mould tool has warm zones for keeping the parison neck soft while the vessel body is chilled. The internal pressure is adjusted to the reqd. storage pressure and the neck pinched and severed by sliding members in the top of the tool. The moulding is ejected after the neck is sufficiently cool to contain the internal press. The closed parison end prevents air from reaching the internal walls sterilised by the processing temps.
