Apparatus for dropping and sealing liquefied inert gases into a can immediately before rolling of a canning can, and applying internal pressure to the can after sealed. Liquefied gases supplied from a liquefied gas main tank to a liquefied gas storage tank set in gas pressure lower than that of the main tank is controlled by a bucket or ball type float valve to maintain a constant liquid level at all times. A given amount of liquefied gases are dropped from a dropping nozzle into a can by means of a dropping valve actuated by a sensing signal of the can....
An apparatus for dropping liquefied inert gases into a can immediately before rolling of a canning can, comprising a storage tank for liquefied inert gases, a valve for dropping liquefied gases opened and closed by a driving device, a dropping nozzle for dropping liquefied gases from said dropping valve, a pressure regulating valve provided on a discharge route of vaporized gases above said storage tank, and a float valve adapted to open and close a liquid feed port for the liquefied gases to said storage tank.
