A liquid dispensing device is provided which dispenses a given amount of liquid from a bottle container which comprises (1) a bottle cap removably affixed to the bottle; (2) a spout tube movable within said cap and located both within and outside of said cap; (3) a handle affixed to the exterior portion of said spout tube and suitable to move said tube as desired within said cap; (4) a series of apertures within said spout tube; (5) a valve seat located at the end of said tube opposite to the end where said handle is located and located within said cap; and (6) an air valve tube removably located within an aperture of said cap. The tube is pushed into the cap and container by the operator utilizing the handle, allowing liquid to flow about the valve seat into the chamber of the cap. The tube is thereafter drawn outward, permitting the valve seat to come into contact with the wall of the cap, sealing and filling the cap chamber. The tube is further withdrawn so that apertures located in an inner wall of the cap chamber are aligned with openings in the tube allowing fluid to flow from the cap chamber into the tube. Simultaneously, an air valve tube is withdrawn from the wall of the cap, allowing air to pressure liquid from the cap chamber into the tube and out of the spout to the designated location.
