Abstract

A process for the production of oriented hollow bodies of plastic material, comprising the following successive steps: (1) formation of elongated preforms one of whose ends is closed and the other is open and has a molded neck, (2) thermal conditioning of the preforms at a temperature that allows the orientation of the plastic material by stretching, (3) introduction of the preforms in blow molds whose impressions are longer than the length of the preforms and reproduce the shape of the desired hollow bodies, (4) blowing the preforms by introducing an expansion fluid into the preforms through its open end, characterized by the fact that the expansion fluid is introduced into the preforms in a direction substantially parallel to its longitudinal axis and at a distance from its depth between 20 and 60% of its length undergoing expansion.
