Abstract

PURPOSE: To seal the vent tube without producing thick inner pool with stable flame, by providing the vent tube sealing nozzle hole present continuously around the circumference and having the opening internal the vent tube through hole only within a given range toward the circumference.
CONSTITUTION: The vent tube sealing nozzle hole 11 present continuously toward the circumference in the vent tube through hole 9 and having the opening within a given range toward the circumference, is formed. Accordingly, the flame jetted from the nozzle hole 11 is reflected internal the vent tube D and the through hole 9, resulting in concentrating to the part where this nozzle hole 11 is not formed. A part of the vent tube D corresponding to the part concentrated with the flame is heated to high temperatures than other parts and softened and molten before the other parts. Then, the molten part is concaved first and sealing is made by the molten part intenal the opposite part. Accordingly, since the part of concave first is extended thinly, no inner pool is caused, thereby preventing the leakage due to cracks and obtaining stable flame.
