A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has an oblate spheroid shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the oblate spheroidal shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

A system for introducing pressurized gas into a liquid, including: (a) a housing adapted to receive a canister of pressurized gas, the housing including a threaded internal surface to receive a threaded neck of the canister; (b) an applicator in fluid communication with the canister and operationally coupled to the housing; (c) a liquid container adapted to hold therein a carbonated beverage; (d) a receiving port adapted to be reversibly mated with the applicator in an airtight coupling so as to facilitate fluid communication of the pressurized gas into the liquid container.

A method includes obtaining a cartridge having a first fluid within an interior of the cartridge, where the cartridge includes a valve; obtaining a container having a second fluid within an interior of the container; obtaining a pressurizer; installing the cartridge within the pressurizer; installing the pressurizer within a container opening at a top end of the container; and opening the valve in the cartridge, to flow the first fluid within the interior of the cartridge through a first flow path in the valve, and a second flow path in the pressurizer into the second fluid in the container.

The invention relates to a carbonation apparatus (10), in particular for the introduction of carbon dioxide to liquid, having a gas outlet which is configured to be introduced into a container (7) which can be filled with liquid, a gas connector which is fluidically connected to the gas outlet via a controllable valve (4), a control device (5) which is configured to control the valve (4), comprising, furthermore: a fixture (1) with a weight determining device for determining a weight of a gas cylinder (3) which is received in the fixture (1) and is connected to the gas connector.

A portable carbonating dispenser utilizes an onboard supply of carbonation gas and a carbonation control module for permitting a user to carbonate base liquid stored in an onboard base liquid container. The carbonation control module may include a user actuated button for selectively activating the carbonation. The base liquid container may include an extended portion for increasing the exposure of base liquid to carbonation gas. A vertical viewing window enables a user to view carbonation and the level of base liquid in the container. An isolation component may be useful to isolate an additive cartridge from carbonation pressure during carbonation in applications where the dispenser utilizes additive cartridges. Safety venting and locking features may be provided on the mode selector to prevent a user from accidentally pressurizing the cartridge space. A refill station may be provided to refill the portable carbonating dispenser.

An integrated device including a vessel, a gas reservoir, a pressure regulation device, a primary filter, and a tap assembly. The vessel is configured to contain a beverage. The gas reservoir is configured to supply pressurized gas within the vessel. The pressure regulation device is configured to maintain an infusing pressure within the vessel and also a dispensing pressure within the vessel. The primary filter is configured to hold solid brewing media, to fit inside the vessel, and to be removable from the vessel. The tap assembly is configured to dispense the beverage from the vessel. Methods are also disclosed.

A cap useful for reviving the carbonation level of a carbonated beverage, the cap configured to be screwed on the opening of the beverage bottle, the cap having a pressurized gas compartment that is sealed until selectively pierced by the user by pressing on a piercing means, after such piercing of the seal, the gas inside the pressurized gas compartment is free to move into the beverage container and into the liquid, providing carbonation to the liquid.

A refillable carbonation container is disclosed. Exemplary implementations may include a base, a tank, a container body, a dispenser, and/or other components. The tank holds a pressurized liquid, such as CO.sub.2. The container body holds a potable liquid, such as water. The dispenser dispenses the pressurized liquid from the tank into the potable liquid, which provides carbonation of the potable liquid.

The systems and methods provide a container assembly comprising: a container having a known storage capacity for storing a liquid; an additive dispensing assembly, the additive dispensing assembly dispensing variable, non-zero quantities of one or more additives into the liquid stored in the container; one or more vessels that each contain one of the additives, of the one or more additives, to be dispensed into the liquid; and a gas dispensing assembly, the gas dispensing assembly releasing a gas into the liquid stored in the container, and the gas dispensing assembly including: an onboard gas tank; a valve assembly; and a gas outlet, and the valve assembly controlling flow of gas from the onboard gas tank, through the valve assembly, and to the gas outlet so as to output the gas into the liquid; and wherein the valve assembly, to perform the controlling the flow of gas, is movable between: an open position, in which flow of gas is allowed to flow from the onboard gas tank to the gas outlet; and a closed position in which the flow of gas is prevented to flow from the onboard gas tank to the gas outlet.
