Abstract
An injection device for simultaneously forming and filling a container by injecting a pressurized liquid in a preform. The device includes a molding cavity, a pressurized liquid source and an injection nozzle in fluidic communication with the pressurized liquid source. The injection nozzle is arranged to be placed in fluidic communication with a preform in the molding cavity. A liquid injection circuit is defined by the injection nozzle, the pressurized liquid source and the preform. Also provided is a volume measuring feature for measuring the volume of liquid injected in the preform from the pressurized liquid source and a pressure measuring feature for measuring the pressure in the liquid injection circuit.
