Abstract
An apparatus for injecting gas under pressure into liquid held in a bottle 5, primarily for injecting carbon dioxide gas into beverages in order to make "fizzy" drinks in the home or other small establishments, comprises a base member 1 including a platform 4 to support the bottle. A housing member 2 is pivoted to the base member about a generally horizontal axis 3 spaced horizontally from the platform so that when the apparatus is opened the bottle can be placed upon, or removed from, the platform. When the apparatus is closed, a dip tube 9 penetrates through the open top of the bottle to permit the injection of gas from a cylinder housed within the base member under the control of a lever 11.
Claims20
An apparatus for injecting gas under pressure into liquid contained in an open-topped vessel, said apparatus comprising a base member including a platform fixed thereto to support the vessel, a housing member pivoted to the base member about a generally horizontal axis spaced horizontally from said platform, the housing member including a gas injection orifice, a coupling for receiving a source of compressed gas and connected to a conduit defining a flow path to lead gas from such source to the injection orifice, a manipulable control member, and means for controlling the flow of gas from said gas source, said means being operable in response to movement of said control member to permit or prevent the flow of gas to said orifice, the housing member being pivotal between a first position which permits the vessel to be placed upon or removed from said platform without penetration of the injection orifice into the vessel, and a second position in which the injection orifice penetrates through the top of the vessel previously placed upon the platform.
