Patent ID: 8864490

Claim:
A device ( 24 ) for injecting at least two pressurized fluids into the axially oriented neck ( 20 ) of a container ( 18 ) in the parison state for forming a final container by deforming said container ( 18 ) by the successive injection of a first pressurized fluid then of a second pressurized fluid, the device ( 24 ) comprising: a first supply pipe ( 25 ) supplying a first pressurized fluid; a second supply pipe ( 30 ) supplying a second pressurized fluid, the second supply pipe ( 30 ) opening into an axial nozzle ( 32 ) which is intended to be arranged concentrically inside the neck ( 20 ) with a first radial gap (j 1 ) so as to allow the first pressurized fluid to pass between the container ( 18 ) and the first supply pipe ( 25 ) through the first radial gap (j 1 ); the second pressurized fluid used for forming the container ( 18 ) consisting of an incompressible filling liquid, characterized in that it comprises a sealing mechanism ( 34 ) that can be made to switch between an open position in which the first fluid is able to pass through the first radial gap (j 1 ), and a closed position in which a seal ( 36 ) plugs the first radial gap (j 1 ) between the nozzle ( 32 ) and the neck ( 20 ) of the container ( 18 ) in a fluidtight manner.
