The present invention relates to a compressed gas supply device. More specifically, the compressed gas supply device includes: a cover; a body configured to accommodate a gas container containing a compressed gas therein and to be installed at an open inlet portion of a food container containing a liquid; a discharging means provided in the body for discharging the compressed gas into the food container by opening the gas container; a coupling means configured to couple the cover to the body; and a sealing jaw formed in the body to prevent the liquid of the food container from being exhausted to the outside by contacting the inlet portion of the food container.

A domestic beverage carbonator for carbonating a liquid in a bottle comprising temperature and pressure sensors that communicate with processor to improve the carbonation process. The device further comprises a CO2 cylinder coupling and a cylinder discharge valve, an exhaust valve, a fill head and a user interface. The user interface further comprises user controls and a graphic display and the fill head has a pressure sensor to sense a pressure in the attached bottle and communicate a pressure signal to the processor and the processor uses the pressure signal to regulate the cylinder valve and the exhaust valve.

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.

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.

A portable bubble water bottle of the present application includes a first space, a second space, an one-way gas valve and a gas cylinder. The second space is located in the first space along the first projection direction. The one-way gas valve connects the first space with the second space. The gas cylinder is located in the second space, and has a gas outlet connected to the one-way gas valve.

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.

Beverages such as beer and soda which contain carbon dioxide or other gases may degrade in quality when subjected to atmospheric pressure, oxygen, and/or light. It may be desirable to store such beverages in containers which prevent exposure to these conditions. An aluminum can is one such container but is associated with the problem of resealing the can after breaking the seal. The described utilities provide for resealing, pressurizing, and/or dispensing from an aluminum can or similar beverage container.

A cap for making a beverage in a threaded bottle includes an inner cap, an outer cap and a flavor container. The inner cap has external threads and internal threads that match the threads of the mouth of the bottle, and the outer cap has internal threads that match the external threads of the inner cap. The cap includes a first releaser for opening the flavor container into the bottle when the cap is being screwed onto the mouth of the bottle. The cap further includes a carbon dioxide container and a second releaser for opening the carbon dioxide container into the bottle when the outer cap and the inner cap are being screwed relative to each other. The disclosed embodiments also relate to a method for making a beverage.
