PURPOSE: A stopper for carbonic acid gas leakage prevention is provided to prevent leakage of carbonic acid gas inside of a beverage container and to drink contents being stored upside down inside of a beverage container without opening a stopper through a valve. CONSTITUTION: A body(100) is connectedly engaged with an entrance unit of a beverage container and an outlet(120) for discharging contents of a beverage container is penetrated and formed in the longitudinal direction. A valve(200) is prepared in the outlet side inside of the body, and opens and closes the outlet. A fixing leg(300) is equidistantly engaged with the circumference of the body, is fixed in the opposite direction of the beverage container while sealing the beverage container and supports the beverage container upside down. A leg engagement groove(110) protruded to be equidistantly apart is formed in the circumference of the body. A hinge pin engagement groove(113) in the both sides of the leg engagement groove is formed, respectively. The fixing leg is vertically rotated in which a hinge protrusion formed in the edge of one side of the fixing leg toward the both sides is inserted into the hinge engagement groove. The valve opens and closes an outlet(120) of the body by selecting and using a button technique(a) or a lever technique(b) or a screw technique(c).
