(Industrial Application Field) The present invention relates to a method for manufacturing a fuel wick for a gas lighter using liquefied fuel. (Prior art) Conventionally, wicks for gas lighters have been manufactured by filling a mold with polyethylene powder, applying mechanical vibration to increase the degree of filling, and then heating and sintering to shape the mold. This method had the problem that the degree of filling of the powder was non-uniform, and the liquefied gas was not sucked up uniformly during suction, and as a result, the flame was often unstable. Additionally, during mass production, it took about 20 seconds to apply vibration, which limited the speed of production. Furthermore, when applying mechanical vibrations, the noise was large, which caused problems in terms of the manufacturing environment. (Object of the Invention) In view of the above problems, an object of the present invention is to provide a method for manufacturing a gas lighter wick that is homogeneous and has good flame stability at high speed and with low noise. (Structure of the Invention) The method for producing a wick for a gas lighter of the present invention involves applying ultrasonic vibration (i.e., vibration with a frequency of 1.6 KHz or more) to the powder for a predetermined period of time when filling a mold with powder of a core material such as polyethylene. It is characterized in that the core is formed by heating and sintering. (Effects of the Invention) According to the manufacturing method of the present invention, it is possible to uniformly fill the core material powder in an extremely short period of time (about 6 to 10 seconds) using ultrasonic vibration, so that the core material powder can be uniformly filled (i.e., the wicking rate is and uniform weight) at high speed,
can be manufactured. Moreover, since it uses ultrasonic waves instead of mechanical vibrations, it enables silent filling without noise, and it also improves the manufacturing environment. Furthermore, it does not damage the mold as compared to mechanical vibration, which greatly contributes to the lifespan of the mold and ultimately to cost reduction. (Example) As shown in Fig. 1, a filling chamber 1 in the shape of a wick
A mold 10 having a large number of holes 1 is placed in a metal vibration case 1.
2, and after attaching the powder receiving frame 13 on top of this, polyethylene powder (80~
300 mesh) to fill the filling chamber 11 with powder. At this time, an ultrasonic vibrator (horn) 15 is brought into contact with the vibration case 12 from below to apply ultrasonic vibrations of, for example, 18 KHz for 6 to 10 seconds. The powder thus filled is sintered by a conventional method to produce the core 20. As shown in FIG. 2, a 3 mm portion of the lower end of the core 20 thus produced was immersed in liquefied gas, and the suction speed was measured. The measurement method was to measure the time taken for alcohol to be sucked up from 5 mm to 15 mm from the bottom. (Room temperature: 20°C) The results are shown in the table below.

The time was 4.08 seconds, but it was not achieved by the present invention.
The suction time was as short as 2.78 seconds, indicating that the suction was stable. This has a close relationship with the stability of the flame upon ignition, and the wick manufactured according to the present invention is effective in realizing a lighter with a stable flame.
