Abstract: A method for making a container made of a plastic material, provided with a base including a standing ring forming a support flange and a diaphragm extending from the standing ring to a central portion, the diaphragm being capable of standing in an outwardly-inclined position, wherein the diaphragm connects to the standing ring at an outer junction forming an outer articulation of the diaphragm; wherein the diaphragm connects to the central portion at an inner junction forming an inner articulation of the diaphragm; whereby the diaphragm is invertible with respect to the standing ring from the outwardly-inclined position to an inwardly-inclined position; and wherein, in the outwardly-inclined position, the diaphragm has an outer curved portion and an inner curved portion of opposite curvatures.

Abstract: A method for producing a container from a blank, inside a forming unit having a mold and a movable insert controlled by a variable-flow solenoid valve, a control unit linked to the solenoid valve. The method comprises developing a boxing curve characterizing the successive positions of the insert; determining, based on a reference blowing curve, points of inflection; measuring, on the boxing curve, distances actually travelled by the insert between points in time, some of which correspond to these points of inflection; and comparing the values of the measured distances with nominal values. If there is a difference between a measured value and a nominal value, controlling, by the control unit, a modification in the flow rate setpoint of the solenoid valve for the next production cycle.

Abstract: A method for producing a container provided with a base, in a mold that includes a base with a base block with a raised molding face and a central opening, and an insert mounted in the central opening. The insert has an end face with the imprint of a central area of the base of the container, movable between: a retracted position with the end face extending in the extension of the molding face, thus completing therewith the imprint of the base of the container; a protruding position with the insert protruding relative to the central opening. A step of boxing the central area of the base of the container includes moving the insert to the protruding position to exert pressure against the central area of the base and increase the clearance of the central area relative to the clearance at the end of the blowing.
