Abstract

PROBLEM TO BE SOLVED: To make ultrasonic melt-bonding unnecessary and enhance reliability by forming a recess in the side wall of a recessed part and fixing a sealing member to a lid by a projection part being fit to the recess. SOLUTION: A recess 12 is formed in the side wall of a recessed part 3a formed in the specified position of a lid 3. A valve presser cap 11 made of plastic for example is fit to the recessed part 3a. A projection part 11a is formed on the outer circumferential surface of the cap 11, and the projection part 11a is fit to the recess 12. The recess 12 is engaged with the projection part 11a, and the coming off of the cap 11 from the recessed part 3a is obstructed. Since the cap 11 is easily fit to the recessed part 3a, fitting work is made easy, and ultrasonic melt-bonding is made unnecessary. Troubles caused by ultrasonic melt-bonding are eliminated. Since equipment for ultrasonic melt- bonding is made unnecessary, manufacturing cost is reduced.
