GAS FILLING DEVICE, GAS FILLING METHOD, AND METHOD OF PRODUCING GAS EJECTION DEVICE

摘要

A gas filling device has a reception section (61) for receiving a gas container (5) and a gas ejection device (1) at which an operation member (9) for opening and closing the gas container (5) is provided; a gas filling section (62) in which a feeding path (68) for feeding gas and a gas discharge path (69) for discharging the gas are formed and to which one end of the reception section (61) is exposed; a lid body (64) for sealing the gas filling section (62); and a release member (65) for engaging with the operation member (9) to release the gas container (5). The gas filling section (62) having the gas ejection device (1) received in the reception section (61) is sealed by the lid body (64), the gas container (5) of the gas ejection device (1) is released by the release member (65), and then the gas is introduced from the feeding path (68) into the gas filling section (62) to immerse the gas ejection device (1) in the gas. As a result, the gas container (5) is filled with the gas.
