Abstract
A gas filling method includes the steps of: intermittently transferring a bag to arrange the bag at a gas blowing processing position; inserting a blowing nozzle into a gas guide path of the bag in the gas blowing processing position; pinching the blowing nozzle arranged in the gas guide path from outside of the bag with a pair of pinching members in the gas blowing processing position; causing the blowing nozzle to eject the gas in such a manner that the gas is sent to the gas accommodation portion in the gas blowing processing position in a state where the blowing nozzle is pinched via the bag by the pair of pinching members; and closing the gas accommodation portion in an airtight manner in the gas blowing processing position in a state where the blowing nozzle is arranged in the gas guide path.
