Disclosed is a refillable gas container for supplying fuel to a portable gas burner. In the gas container, when an injection nozzle is pressed and thereby an orifice having been blocked by an O-ring is opened, gas contained in a container body is discharged to the exterior. When the gas is refilled into the gas container, the pressure of the gas applied through a nozzle hole of the injection nozzle from a gas filling apparatus moves a needle valve, which has been in a state of blocking the nozzle hole of the injection nozzle, against the spring force of a spring, so as to open the nozzle hole. In result, the gas is filled into the gas container through a filling hole formed through a side wall of a nozzle cap. Therefore, the abrasion of the O-ring is minimized and the life span of the refillable gas container is prolonged at least by two times. |
