The high pressure gas can be injected into the container by utilizing the pressure difference. Then, the high pressure gas can be filled in the container by sealing the opening with the sealing means after the high pressure gas is injected. At this time, since the high pressure gas is not directly filled from the compressor but indirectly via the buffer container by using the pressure difference between the container and the buffer container, the high pressure gas is not directly influenced by the discharge performance of the compressor. Can fill the container accurately in a short time. Also,
By surrounding the opening in an airtight space, the space can be used to perform the filling operation and the sealing operation at the same time. Moreover, since the holding means is provided with a space surrounding the opening, the opening can be airtightly enclosed only by holding the container by the holding means. It is possible to quickly shift to the high pressure gas filling operation of the container. Since the supporting means for supporting the bottom of the container in a conductive manner and the sealing means are connected to the welding power source, the sealing means can be easily sealed by pressure-bonding the sealing means to the opening. Further, since the supporting means is fitted to the bottom of the container, the supporting state of the container can be stabilized and accurate welding can be performed. Further, the temperature control / pressure control means of the buffer container enables the high-pressure gas to be filled in an optimum state according to its properties.
