Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a sealed container capable of reducing a pressure loss in an annular packing groove and positively performing sealing and opening in the sealed container that closely adheres or separates an annular packing stored in the annular packing groove to or from a door or a sealed container by pressurizing or depressurizing the annular packing groove and seals or opens/closes the inside of the container. SOLUTION: The sealed container is for closely adhering or separating the annular packing stored inside the annular packing groove 12 with respect to the door by increasing or decreasing the pressure inside the annular packing groove 12 and sealing or opening the inside of the container provided to the container, and includes a fluid line 20 for increasing and/or decreasing the pressure inside the annular packing groove 12, and three fluid-distribution-holes 13 provided in the container for connecting the fluid line 20 with the annular packing groove 12 at three locations.
