Abstract. This invention relates to a carbonating apparatus which is designed primarily for the domestic market, but not solely as it has a place in the commercial field of hotel bars and restaurants. A small carbonating apparatus used to carbonate various liquids ( fruit juices, beer, wine, milk, water, soft drinks and re-carbonate previously carbonated drinks, or to pressurize again bottles of carbonated drinks that were opened, to keep in good condition ), has an outer casing or housing which connects to a cylinder of compressed carbon dioxide gas, and has located within a filter, two discs, drilled and grooved to combine together to form a reduction valve, drilled airways from the discs through a series of three pistons, the airways branch to the outside to include a pressure gauge and a pressure relief valve, which is only in communication with the pressure in the airways but can control the pressure within the sealed bottle and can in certain aspects of the invention be used as an indicator as to when the correct pressure has been reached in the bottle. A series of three pistons combine together to provide a means for a piston in conjunction with a spring to control the pressure within and close, a second to give final closing in the central postion, and a third piston which is ocerated by the bottle, to pass into the non-return valve through the bottle cap, when depressed by the bottle activates the gas flow through and around the previously mentioned pistons. In a second aspect of the present invention an injector block replaces the injector piston end functions with a pressure relief valve to control the pressure in the bottle whilst not being in direct communication with the contents of the bottle, thus permitting a pre-mix system to be used. The insert in the bottle cap provides a shoulder to keep the washer in place , a well or recess to accept and position an o-ring for sealing on the injector, and an non-return valve. The air is removed from the bottle by deforming and the further de-aeration by warming the contents of the bottle, The amount of liquid level in the bottle is of importance to allow the maximum amount to be carbonated at one time , and to provide maximum space in the bottle to receive CO2 to be agitated into the beverage. The sealed bottle method permits the bottled to be removed from the carbonator and to be agitated, to induce the beverage to absorb the CO2.
