    Abstract: An apparatus and method for introducing a gas under pressure into a container of liquid having a cap. A hole is punched through the cap. A hose, having an end, is extended through the hole to the inside of the cap, and the check valve tube forced into the hose from inside the cap. The tube forces the hose outward against the surface of the hole preventing leakage. A gas under pressure will be retained in the container by the check valve.
