PROBLEM TO BE SOLVED: To provide a gas filling and packaging machine that can be simplified, also can narrow an installation area, reduce packaging costs, prevent even light-weighted packaged articles from being ejected from a packaging bag when filling the bag with a gas, and further eliminate the necessity of cleaning due to the ejection so as to improve production capability.SOLUTION: A gas filling and packaging machine 1, which is configured to insert packaged articles into a packaging bag a and fill the bag with inert gas, comprises: a singularity or a plurality of grip pairs 2 which hold the packaging bag a; a movement body 3 for moving intermittently the grip pairs 2 for every multiple steps; a liquefied gas dripping device 4 that drips liquefied inert gas into the packaging bag a supported by the grip pairs 2; warming devices 7a and 7b for promoting evaporation of the liquefied gas dripped into the packaging bag a; and top seal devices 6a and 6b for sealing the vicinity of a bag mouth of the packaging bag a filled with the packaged articles and the liquefied gas.SELECTED DRAWING: Figure 4 |
