A container that dispenses a carbonated drink such as beer has a pressure regulator that controls the pressure of the dispensed fluid with a pressurized carbon dioxide. The carbon dioxide is released to maintain the desired pressure by a pressure regulator that opens a valve when the pressure is too low in the dispensed fluid and closes a valve when the pressure is high enough in the dispensed fluid. The pressure regulator is easily adjusted without the use of a tool during operation by simply rotating the pressure regulator's cap on its threads.
