Abstract
A portable apparatus for aerating liquids includes an aerating head, a mechanism for supplying gas to the aerating head from a cylinder when a control button is depressed, a platform for lifting a bottle containing liquid to be aerated into sealing engagement with the aerating head, and a rotary cam operable by a handle to raise and lower the platform. A pre-compressed coil compression spring is interposed between the platform and a button engaged with the cam to ensure adequate sealing pressure between the bottle and aerating head.
