Method of and apparatus for introducing inert gas into a can.

摘要

The lower edge of the peripheral wall (b) of a can cap (A) and the upper edge of a can barrel (B) are spaced from each other by a gap. Streams of an inert gas from different groups (92, 91) of injector nozzles (9) are injected, from outside of the gap, through the gap into the can cap (A) and the can barrel (B), respectively, to replace air in the can cap (A) and the can barrel (B) with the injected gas. Then the can barrel (B) is fitted in to the can cap (A), and secured thereto to entrap the injected gas in the can barrel (B) and the can cap (A).
