<p>A file/nozzle assembly (17) is adapted to be pressed down only when it receives an ignition operating force. When the file/nozzle assembly (17) is pressed down, a valve rod (13) is opened, and a liquid metering space is filled with the gas from a tank (2) but, when the finger pressure is removed, the valve rod (13) is closed at once. The gas is then supplied from the liquid metering space to a discharge nozzle through a gas metering space, and the flow rate of the gas being discharged is controlled by primary and secondary filters (15, 19) provided on the front and rear sides of the gas metering space, respectively, and the gas in the metering spaces is discharged continuously for a predetermined period of time. Namely, the discharge nozzle continuously emits a flame for a predetermined period of time, and then puts it out.</p> |
