Abstract

PURPOSE: To perform packaging operation efficiently using simple construction without providing a chamber for replacing gas by providing a seal means for packaging, comprising a temporary seal means and a main seal means and providing a gas seal means between said seal means.
CONSTITUTION: A rotary table rotates intermittently and goods to be packed are placed in a container 2 having reached a specified position and thereafter a temporary seal means brings a covering film 11 close to the upper opening of the container 2 having reached the specified position, keeping the film in parallel with said opening, to thermally bond the film 11 to the opening, with at least two sections on the periphery of the opening being left unbonded, leaving, for example, four unbonded sections A, whereby the film 11 is cut off along the outer periphery of the container. And then, regarding a gas filling means, a suction means 18 sucks up the unbonded sections A of the film 11 utilizing vacuum to provide openings, whereby a gas flush nozzle 19 is inserted into said opening to feed inert gas. And a main seal means thermally bonds all the sections A of the film 11 of the container 2 which is intermittently rotated.
