Abstract
A beverage carbonating apparatus for consumer use comprises a stand supporting a gas bottle and a nozzle, for insertion into the neck of a container holding the beverage to be carbonated, the nozzle being pivoted to the stand for movement about a horizontal axis between a first, inclined position where the container nozzle may be inserted into or removed from the container and a second, vertical position where carbonation occurs.
Claims21
A carbonating apparatus comprising a stand holding a gas supply means, an injecting nozzle pivotally mounted to the stand for movement about a substantially horizontal axis, said nozzle being adapted to pass through an opening of a bottle or other container and into a liquid contained therein, said nozzle being pivotal between a first inclined position allowing the bottle or other container holding the liquid to be carbonated to be introduced into the apparatus and to be penetrated by said nozzle and a second substantially upright position, supporting means to support the bottle at said second position so that said liquid may be carbonated by gas introduced through said nozzle from said gas supply means via a gas supply system means to seal the opening of the bottle or other container while being carbonated, said means comprising a stopper on said ejecting nozzle, said stopper being slideable along the nozzle to press against the opening of the bottle or other container under the influence of biasing means.
A carbonating apparatus comprising a stand adapted to support a gas supply means, a housing pivotally mounted to the stand and carrying a gas injecting nozzle, the housing being adapted to receive a bottle or other container of liquid to be carbonated and being pivotal between a first position where the housing is swung away from the stand to allow the bottle or other container to be inserted or removed from the housing and a second position where the container lies close to the stand and the bottle or other container is enclosed for protection in the event that the bottle or other container breaks during carbonation, and stopper means to seal off the open mouth of the bottle or other container when at the second position with the nozzle entering the mouth and means enabling gas to be injected from the gas supply means through the nozzle when the nozzle is in the second position, said stopper means having biasing means to press it against said open mouth, said biasing means comprising a chamber above the stopper which is charged with gas pressure and in which a portion of stopper is sealingly slideable, that portion having a greater area exposed to the gas than the stopper portion which is exposed to the gas in the bottle or other container so that under the effect of the differential force created by equal pressures operating oppositely on unequal areas of the stopper, the stopper is forced into sealing engagement with the bottle or other container.
