At least one gas is supplied to the applicator via a least one supply element, at least sections of which are arranged in a horizontal direction next to a transport path of the applicator. The supply element comprises at least one outlet opening facing towards the applicator. At least one pressure-applying element is arranged between the applicator and the supply element and is resiliently clamped between the applicator and the supply element.

Abstract: The method serves for the plasma treatment of container-like workpieces. The workpiece is inserted into an at least partially evacuable chamber of a treatment station. The plasma chamber is bounded by a chamber base, a chamber cover and a lateral chamber wall. The plasma treatment causes a coating to be deposited on the workpiece. The plasma is ignited by microwave energy. The coating consists at least of a gas barrier layer and a bonding layer arranged between the workpiece and the gas barrier layer. The gas barrier layer contains SiOx and the bonding layer contains carbon. The gas barrier layer is produced from a gas that contains at least one silicon compound and argon.

Abstract: The method and the apparatus serve for sterilizing parisons made of a thermoplastic material which are provided for producing blow-molded containers. Sterilization is carried out using a plasma. A sterilizing device is provided, for this purpose, with a plasma generator.

Abstract: A method and device for producing blow-molded containers, at least some regions of which are sterile. A parsion made of thermoplastic material is first heated and then exposed to a pressurized fluid. A sterilization means is introduced into an area of the parison.

Instead of maintaining the entire area of the blowing device as a sterile space, the parison is transported from the sterilization site to the blowing unit at least along a portion of a transport path along a sterile channel.
