Abstract
A device (24) for injecting at least two pressurized fluids into the axially oriented neck (20) of a container (18) in the preform state in order to form a final container by deforming the container (18) by successively injecting a first pressurized fluid and then a second pressurized fluid, the device (24) including: a first duct for supplying a first pressurized fluid; a second duct (30) for supplying a second pressurized fluid; and an axial nozzle (32) into which the second supply duct (30) opens, the nozzle being intended to be placed concentrically inside the neck (20) with a radial gap (j) so as to allow the first pressurized fluid to be injected into the container (18) through the radial gap (j), characterized in that the second pressurized fluid used for forming the container (18) consists of an incompressible filling liquid.
