Diploma thesis deals with the concept of aseptic dosing pressure vessel. The first part describes the requirements for the vessel used in the technological process in the formation. Further on we present current Slovenian legislation and standards for the design and manufacture for dosing containers. Thesis second part is devoted to the calculation according to standard SIST EN13445. Calculations were made for the thickness of the pressure vessel coating, vessel connections and lifting ears. Particular attention was paid to fatigue control of the welded joints on the vessel coat. As a safety element, a safety valve is used, for which a flow conversion is performed. The coupling clamp for connecting the vessel to the reactor is tested for earthquake loads. Instructions for use and maintenance of the container are also included.
