Abstract: Method and apparatus for the gasification of liquids employing a separable pressure vessel which is easily dismantled for cleaning. The pressure vessel is charged from a gas source and provided with a relief valve that prevents the charging pressure in the vessel from exceeding a maximum pressure. Gas is introduced into the pressure vessel through a sparging orifice with an end that is also easily removable for cleaning. The pressure vessel has an outlet employing a single piece dispensing lever which includes not only ribs for opening the valve at the base of the pressure vessel but also an integrally molded restoring spring which has a special configuration for consolidating many of the functions which required separate pieces in the prior art.
