An injection device having an inlet for receiving a fluid, an outlet for injecting the fluid and a chamber therebetween. A control rod is provided in the chamber and includes a duct extending through said control rod. A central rod extends in the duct and is movable between a retracted position and an active position. The central rod and the duct being arranged to prevent fluidic communication between the duct and the chamber when the central rod moves between its retracted and active positions. The central rod and the control rod are further movable relative to each other into a cleaning position, in which the duct is placed in fluidic communication with the chamber.

A container-fabricating apparatus having an injection head establishing fluid communication between an injection fluid port disposed therein and a preform disposed in communication with a nozzle of the injection head. The apparatus also including a stretching rod moveable between a position projecting from the injection head through the nozzle and a substantially retracted position. The apparatus further includes a cleaning chamber at least partially defined by a hollow, elongate housing contiguous with and extending from the injection head, a plurality of cleaning chamber ports in a wall of the housing establishing fluid communication with the cleaning chamber, the stretching rod being substantially disposed within the cleaning chamber when disposed in the substantially retracted position.
