PROBLEM TO BE SOLVED: To take out contents from a mouth of a valve by breaking a thin part formed on a bottom of a metallic container, bringing a filling machine into contact with the bottom for supplying air into the metallic container and raising a piston in the metallic container by pneumatic pressure. SOLUTION: A thin part is formed at a center of a bottom 6 of a metallic container 1, and at the time of taking out contents 8, the thin part is broken to form an air supply hole 4 at the bottom 6. A mouth of a filling machine 5 is brought into contact with the air supply hole 4 at the bottom 6, and air is supplied from the air supply hole 4 into the metallic container 1. A piston 7 received in the metallic container 1 is pressed from a lower part of the container 1 by pneumatic pressure to have it raised, and a valve 9 is opened, thereby taking the contents 8 out of the container 1. Thus, the airtightness of the contents can be held until it is used, and residual contents in the metallic container can be remarkably reduced. |
