PURPOSE:To simplify the production process by fixing a slidable piston to a bottomed container, opening a filling part for an atomization agent capable of being closed by a shutoff plug at the lower bottom wall, and fixing a valve mechanism at the upper opening. CONSTITUTION:An aluminum material is press-worked, and then drawn to form the bottomed container 1 having a U-shaped section from the upper opening to the lower bottom wall 3. The filling port 4 for an atomization agent is bored in the lower bottom wall 3, and a slidable piston 5 is airtightly inserted into the container 1 from the upper opening 2. After the piston 5 is inserted, the upper part of the container 1 is pressed from the outside, and caulked to form a protruding engaging part 6. The contents other than the atomization agent are then filled into the container 1 from the upper opening 2, and positioned above the piston 5. A valve mechanism 7 is then inserted from the upper opening 2, and the valve mechanism 7 is engaged with the upper opening 2. |
