The invention relates to a beverage carbonator (1) having a basic unit (3), wherein the basic unit (3) comprises: a plurality of pressure container receptacles (4) for receiving a corresponding number of pressure containers (5), and a beverage container receptacle (6) for receiving a beverage container (7).

A carbonation machine with integrated water treatment. The carbonation machine may include a carbonation system for carbonating water in a bottle attached to a carbonation head of the system, a detachable water reservoir, configured to be mounted on a base with an outlet port to allow outward flow of water from the reservoir, piping connecting the outlet port of the water reservoir to transfer water from the detachable reservoir and to pour the water into the bottle, a pump for pumping water out of the water reservoir and transfer the pumped water via the piping, a controller configured to control the pump, and one or more water treatment components fluidically connected to the piping to apply water treatment to water flowing through the piping.

Beverage carbonation apparatus having a carbonating system including chassis side plates, a bottle interface assembly, a release handle assembly hingedly coupled to a gas release system adapted for engagement with a gas canister, including a gas release button for selective activation by a user and a push rod coupled thereto, and a valve assembly carbonating system adapted to communicate gas from a canister coupled to the gas release system to a bottle fitted to the bottle dispensing assembly, including a bottle pressure control valve.

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 a rounded shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the rounded 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.

An apparatus and method are provided for dispensing gas to a fluid, such as a beverage, through a delivery system from a vessel containing the gas into another vessel containing the fluid.

A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage.

Provided is a container for liquids associated with a carbonator is provided including a base, a containment body, the container body and the base defining a first inner volume for a liquid, and an opening closable by a cap, configured to allow access to the liquid in the first inner volume, and wherein the base includes constraining means for a gas container having a second inner volume for the gas, a connection configured to place in fluidic connection the second inner volume with the first inner volume, a valve configured to obstruct or free the connection, and control means configured to control from outside the inner volume of the valve, and wherein the connection is separate from the opening.

A bottle, in particular a reusable and refillable bottle for CO.sub.2-containing drinks, which can be carbonated and stored in the bottle. A bottle with better usage properties is to be achieved. The bottle includes a closable liquid container with an adapter which is attached or flanged to the base of the liquid container and which contains a CO.sub.2 tank.

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 connector for connecting a gas canister to a carbonation machine includes holding structure with a threaded socket that is configured to hold an exteriorly threaded valve head that is screwed into the socket to enable operation of a gas release mechanism of the carbonation machine to release a gas from the gas canister. A rotatable projection extends distally from the holding structure and that is configured to engage cooperating structure on the gas canister. When the valve head is fully inserted into the socket, a gasket in the socket is sufficiently compressed to prevent escape of the gas between the valve head and the socket when the gas is released from the gas canister compression while overtightening damage to the gasket is prevented.
