SOLUTION: A wedge-shaped score (notched part) in the cross section for instance obtained by a cutting process is circularly shaped in a zone 13 forming an opening at the external face of a container body 3. And a pouring cylinder 1 in which a male screw 2 is formed at the outer peripheral face thereof is fixed to the outside face of the container body 3 so as to include the zone 13. A cylindrical pushing-in piece 4 is inserted at the inside of the pouring cylinder 1. By pushing down the pushing-in piece 4, the score 5 is cut off and the zone is separated from the container body 3 and the cap is opened. |
