PURPOSE: To provide a gas-barrier property corresponding to contents by a method wherein a break line is formed to a cylindrical part to divide a pliferproof skirt part on the lower side from a main part on the upper part, and an outer cap provided with an internal thread for meshing with an external thread on an inner stopper is formed to the inside of the main part. CONSTITUTION: A bottle 1 is formed, with a groove 2 running continuously in the circumferential direction provided at the periphery on its mouth and a plurality of ratchets 4 provided at the inside of a straight part 13 on the lower side of the groove. A break line 17 extending in the circumferential direction is formed to a cylindrical part hanging down from the periphery of the top face. The break line 17 divides a pilferproof skirt part 15 on the lower side from a main part 14 on the upper side. An outer cap 8 with an internal thread 10 for meshing with an external thread 9 of an inner stopper 7 provided is formed to the inside of the main part 14. Thereby, a gas-barrier property corresponding to contents can be provided for the sealing structure. |
