초록

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....
