The invention relates to a device and a method for plasma treatment of hollow bodies. The invention is in particular suited for the protective plasma treatment of the inner surface of thermally sensitive hollow bodies such as plastic bottles. The plasma treatment according to the invention can, for example, consist of chemical activation, sterilization, cleaning or coating. One or more hollow bodies are put into a processing chamber for treatment. The processing chamber is in fluid connection with at least one plasma source. An exhaust device on the processing chamber generates a negative pressure in the processing chamber relative to the plasma source so that plasma can expand out of the plasma source into the processing chamber and hollow body. |
