Abstract
The invention relates to a method and installation for the production of a plastic container (1). The inventive method comprises: (i) a step involving the thermal conditioning of at least some areas (2) of a preform (3) of the container, such that the temperature of said areas exceeds the glass transition temperature of the constituent material thereof; and (ii) a step involving the injection of a fluid into the preform (3) so as to cause the preform to expand in order to shape same into a container. According to the invention, unrestrained expansion of the above-mentioned areas of the preform is performed, i.e. without a mould, by controlling at least one injection parameter of the fluid in order to obtain the definitive container (1).
