[Prior Art] With the improvement of living standards, preferences have diversified,
The production method of daily necessities is also shifting from mass production to high-mix low-volume production, and the production machines are diversifying accordingly. Also in the packaging field, for example, packaging that maintains the freshness and flavor of powdered granules such as black tea, green tea, and coffee, and the medicinal effects of herbal medicines for a long period of time, and eliminates oxygen that causes food poisoning bacteria, mold, and insects. As a machine, many inert gas filled packaging machines have been manufactured. Such a conventional packaging machine seals inert gas after deaeration in a vacuum packaging process, and can be classified into two types, bag packaging and tray container packaging, in terms of packaging form. In any case, there are those that use a vacuum box for degassing or incorporate a gas replacement device, and in the pillow packaging machine incorporating the latter, inert gas is sent from the beginning or the middle of the seal by the heat sealer and remains. It expels the air.

A vacuum box and a gas replacement device can be provided to reduce the residual air ratio of the package. In the gas-filled packaging in this case, a gas filling process is generally inserted between the deaeration work and the sealing work in the vacuum packaging process, a switching valve for gas filling is provided in parallel with the vacuum circuit, and the control unit is filled with gas. A timer has been added. Nitrogen gas is the most used gas for filling, and mixed gas with carbon dioxide gas is also used. As the packaging material for the gas-filled packaging, a laminated film having a high gas barrier property, that is, a laminated film in which an aluminum foil or the like is laminated on nylon, vinylidene chloride, EVAL is used.

However, even when the above-mentioned inert gas-filled packaging machine is applied to a conventional pillow type packaging machine, the inert gas is continuously filled in each divided pillow (bag). It was very difficult to pump and expel air, and thus to completely eliminate oxygen in the pillow. For this reason, it is effective to put a gas in the vacuum state before filling it with an inert gas, and to put a vacuum box and a gas replacement device together. Work becomes discontinuous. In addition, there are problems that the packaging machine is complicated and large, and that the packaging work speed is slow.
