A pressurizing beverage dispenser removably attaches to the threaded neck of a container and includes a main body having a handle portion and a head portion. A valve spout on the head portion is moveable between a closed position and an open position. A hand operated squeeze bulb pump fitted to the handle delivers air through the discharge opening and pressurizes the container interior when the valve spout is closed. The handle portion can be structured and disposed to hold the squeeze bulb in a manner which prevents undesirable movement of the squeeze bulb and blockage of airflow to the container.
