ABSTRACT:
An oriented plastics container, e.g. bottle, is heat set by holding an unheat set container against the heated walls of a split mould by means of gas under pressure, and thereafter cooling the container, e.g. by cooling the mould or by displacing said gas with a cooling liquid under pressure, and then removing the container from the mould. The liquid may be that to be packaged in the container.
