Abstract (en)
[origin: WO2006032773A2] The invention concerns a plug-electrode device for internal plasma treatment of a container (3) using an activating gas or a gas or a treating gas mixture consisting of a rotating mobile block body (5), comprising means for injecting the gases and having a cavity (8) for receiving and maintaining the neck (2) of the container (3), a hollow central electrode (11) electrically connected to a high voltage generator is immersed in the neck (2) and surrounded over its part inside the neck (2) by a coaxial conductive ring (15) spaced apart from the central electrode (11) by electrically insulating spacer means, said conductive ring (15) having at least one through ionizing channel communicating with a mixing and injecting chamber (20) separating it from the adjacent walls of the neck. The invention is of interest to manufacturers of machines for plasma treatment of containers.
