Abstract
Improvements in the manufacture of containers of blown plastic material with calibrated neck, characterized by the fact that to avoid buckling and warping of the walls of the neck to be calibrated in the partially formed container that is inserted inside the mold, then, after the at this moment the tube, filled with air, is introduced inside said mold and when it is closed, a suction is carried out in an annular vacuum chamber, placed around the extension of the neck of the container in order to force the walls of plastic material of the tube corresponding to the aforementioned prolongation of the area of the neck are adhered against the internal perforated walls of the determinant annular parapet of the suction chamber and thus the easy introduction of the nozzle or nozzle for molding and calibrating the neck is achieved of the container inside said neck, that once introduced that one stops making the action n suction.
