PROBLEM TO BE SOLVED: To maintain the airtightness of a sealed container even after the beginning of its use by not removing a cap at the beginning of its use. SOLUTION: The airtight cap of this container is structured by capping and fixing a middle stopper 8 having a shielding panel 8c near a mouth 2 of the container 1, by providing a large diameter ring-shaped belt part 8f at the bottom end edge of the outer peripheral wall 8a of the middle stopper 8, by extruding outward one end part 8g of the ring shaped belt part 8f cut in one position, and by capping and fixing an outer cap 9 on the middle stopper 8. This outer cap 9 comprises a main body cap 10 for capping the middle stopper 8 and an outer cover 11. A guide tube 12 goes down vertically in the main body cap 10, and the section of the bottom end edge of the guide tube 12 formed sharp faces the shielding panel 8c. When the ring shaped belt part 8f is cut and separated from the middle stopper 8 for pressing the outer cap 9 downward, the lower end edge of the outer cap 9 is caught by the outer periphery of the mouth 2 of the container 1, and the bottom end edge of the guide tube 12 makes a notch in the shielding panel 8c. |
