Further, the cylinder-shaped rubber, ring-shaped rubber and round rubber bottom are integrally formed.
Further, the cylinder-shaped rubber and glass bottle opening cooperation.
Further, the cylinder plastic body and chock plug are integrally formed.
Further, the thread groove and thread protrusion cooperate.
The utility model has the beneficial effects that
The rubber stopper of the utility model first fills in rubber plug body when filling in vial, then plastics cock body is screwed into
Cylinder-shaped rubber inner cavity, plastics cock body can increase the leakproofness of rubber plug body, meanwhile, the cooperation of thread groove and thread protrusion
So that plastics cock body is not easy to fall off out of rubber plug body, increase leakproofness；When extracting vial, due to the setting of venthole,
Venthole can make the inner cavity air pressure of cylinder-shaped rubber equal with ambient pressure, when extracting cylinder plastic body, cylinder-shaped rubber
It is interior it is intracavitary will not generate vacuum, can easily back-out, due to cylinder-shaped rubber be cylindrical structure, to the pressure of glass bottle opening inner wall
It is smaller, rubber plug body is easily extracted from glass bottle opening.
