PROBLEM TO BE SOLVED: To provide an ejection plug which conveniently incorporates two opposite aspects including such requirement that the ejection port can be sealed but may not be disconnected wherein it is dispensable as a commercial article and easy removal in disposal. SOLUTION: A longitudinal shallow groove 5 having a width is formed at an appropriate position on an external face of an outer peripheral wall 1 to be fitted to and engaged with an outer periphery of a neck of a container body, two longitudinal thin break lines 2 for cracking are arranged correspondingly to both sides of the groove 5 on an internal face of the outer peripheral wall 1, and a tongue-like tab 3 is incorporated in the groove 5 to have a lower end of the tab 3 connected to a lower rim of the groove 5 via a thin hinge 6. In addition, a protrusion 7 is made to protrude at a middle in the groove 5, and a small hole 8 is drilled at an appropriate position in the middle of the tab 3, and the small 8 is removably fitted to the protrusion 7, thereby providing the tab 3 so that it can be pulled up on the outer peripheral wall 1 in the vicinity of an end of the break line 2. |
