PURPOSE: An air injecting apparatus for preventing leak of carbon dioxide gas from carbonated drink is provided to improve flavor of carbonated drink by reducing leak of carbon dioxide gas with eliminating the gasification space in the container. CONSTITUTION: Air is supplied through an air suction port to an elastic air bag(04), and counterflow preventive units are formed in the air suction port and an air injection port(05). Air is injected from the air bag to a container with closing the air suction port and opening the air injection port in compressing the air bag, and external air is moved into the air bag in restoring the air bag. A pressure plate(06) is installed in the upper part of the air bag, and connected to a push switch(10). A spring(11) is installed in the lower part of the push switch to restore, and an elastic closing link(02) is pressed in the inlet of the container. Flavor of carbonated drink is kept for a long time by injecting air to the container with using the push switch repeatedly after opening the drink container.
