PROBLEM TO BE SOLVED: To provide a plug capable of easily and surely sealing a container body.SOLUTION: The plug 20 opening/closing an opening part 10a formed in the container body 10, includes an outer base member 21, including an outer communicating hole 21a, mounted on the outer surface side of the container body 10 to be in communication with the opening part 10a, and an outer cover member 22 turnably mounted via a turning shaft 23 onto the external surface side of the base member 21. The respective opposite faces of the outer base member 21 and outer cover member 22 have multipolar magnetized patterns formed in a banded state wherein N pole and S pole are alternately arranged, while it is so constituted that when both the multipolar magnetized patterns have come to be in parallel with each other in plane view by the turning of the outer cover member 22, the outer cover member 22 is adsorbed by the outer base member 21 so that the outer communication hole 21a may be covered. |
