PROBLEM TO BE SOLVED: To develop a stopper which can be easily attached or detached and which does not naturally drop out. SOLUTION: This stopper mechanism is made such that an inside protruded engagement claw 41 of an annular stopper 4 is fitted into and engaged with an engaging through-pass hole 2c of a connecting cylinder member 2 fitted to a container 1 having a fluid discharging mechanism to prevent an accidental discharging of fluid, a clearance between the stopper 4 and an actuator 3 is shortened as the discharging is performed and finally, the engagement claw 41 is engaged with the engagement through-pass hole 2c of the connecting cylinder member 2. An inward protuberance at the lower end of an inner wall is engaged with a lower end 2v1de of a connecting cylinder 2v1, together with a recess 52 ascending from both sides of a removing knob 51 extended from a lower end region of the cylindrical stopper 5 fitted to a first deformed connecting cylinder member 2v1. An engaging claw 21v2 protruded from an outer wall of a second deformed connecting member 2v2 is removably fitted to an engaging through-pass hole 43 punched at an outer annular segment 4vx of the deformed annular stopper 4v. Its unsealing and re-sealing can be performed without using any tool, a desired amount of dosage can be assured and its natural releasing is not accompanied. |
