GAS VESSEL AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a gas vessel having good impact resistance and conveying workability, while a skirt part can be connected as strength is maintained of a gas vessel main unit, and a method of manufacture of this gas vessel. SOLUTION: This gas vessel 1 is provided with an almost bottomed cylindrical gas vessel main unit 2 and an almost bottomed cylindrical skirt part 5 consisting of synthetic resin press-fitted to a lower barrel straight part 6 of this gas vessel main unit 2. This skirt part 5 comprises a plurality of protrusions 10 uniformly arranged in an inner surface of a bottom part 5b, through hole 11 formed in the vicinity of the plane center of the bottom part 5b, and a leg part 7 provided in circular annular shape in an outer surface of the bottom part 5b. An impact or the like acting in a lower part of the gas vessel 1 is absorbed by the skirt part 5 having the protrusions 10.
