PROBLEM TO BE SOLVED: To allow a part of a closing body to be broken after use for easy removal by providing a breaking part on an appropriate portion of a peripheral wall. SOLUTION: A breaking part 3 sectioned in a II-shape by a breaking line 4 is provided at a lower end on a side of a peripheral wall 2 to be fitted to an outer periphery of a mouth of a container body A of an extraction plug 1 with a tamperproof seal. At the time of extracting contents, a lid 9 is opened, a pull-ring is strongly pulled for breaking and removing the tamperproof seal, and an extraction cylinder 6 is opened. After extraction, the lid 9 is closed, and the extraction cylinder is closed. Thereafter, the lid 9 is opened/closed at each extraction. When the contents are used up and the container is separately disposed as a resource, the breaking part 3 is removed by cutting off the breaking line 4 of the peripheral wall 2 by a bottle opener, a screwdriver or the like, and the bottle opener or the screwdriver is hooked on a rim of a broken opening after removal to have the plug 1 removed from the container body A. |
