PURPOSE: A container stopper capable of easily discharging contents therein is provided to remove the necessity of opening the stopper when discharging the contents and prevent the contents from being discharged to the outside even though the container is inclined. CONSTITUTION: An upper air inlet tube(51), whose one end is curved downward, is protruded upward at a predetermined portion on an upper surface of an injection inlet stopper(50). A plurality of air inlet holes(52) are formed in an upper end of the upper air inlet tube to inflow external air. A lower air inlet tube(53), whose one end is curved upward, is provided so that the upper air inlet tube is extended downward with centering the upper surface of the stopper. Ball members(70) are included within the lower air inlet tube to open and close the lower air inlet tube. A protrusion(80) is formed at a predetermined location inside the lower air inlet tube to restrict movement of the ball members. A plurality of air discharging holes(54) are formed on the outer surface of the lower air inlet tube to discharge the air flowed through the air inlet holes into a container. An inlet tube stopper(55) includes a plurality of holes(56) for inflowing contents, to flow contents into the lower air inlet tube by opening and closing one end of the lower air inlet tube.
