This invention relates to a novel method and system for dispensing CO2 vapor without over pressurization from a system having multiple containers. The system includes one or more liquid containers and one or more vapor containers. The system is designed to operate in a specific manner whereby a restricted amount of CO2 liquid is permitted into the vapor container through a restrictive pathway that is created and maintained by a shuttle valve during the filling operation so that equalization of container pressures is achieved, thereby allowing shuttle valve to reseat when filling has stopped. During use, a pressure differential device is designed to specifically isolate the vapor container from the liquid container so as to preferentially deplete liquid CO2 from the vapor container and avoid over pressurization of the system until the vapor container becomes liquid dry. The system can be operated so that at least 50% of the CO2 vapor product is dispensed from the vapor container.

This invention describes a device which attaches to the threaded base connector of a whipped-cream dispenser and which allows for a simple and quick charging of said dispenser using disposable compressed gas canisters. This device allows for safe charging of the dispenser and employs multiple directions of lever operation/movement to provide this safety.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

The present disclosure discloses a portable carbon dioxide adapter system. The system includes a first collar assembly for connecting to a liquid carbon dioxide source; a gasifying/flow adjusting assembly that converts liquid carbon dioxide into gaseous carbon dioxide and may adjust gas flow; an injection nozzle valve assembly that abuts against a gas inflow valve of a gas-injection-by-adapter object so as to inject the gaseous carbon dioxide; and a second collar assembly with one end slidably receiving the injection nozzle valve assembly and the other end being securely connected to the gasifying/flow adjusting assembly. The liquid carbon dioxide source is a disposable carbon dioxide gas cylinder, and an opening unit for piecing the disposable carbon dioxide gas cylinder is mounted within the first collar assembly; and the gasifying/flow adjusting assembly has a volume-adjustable hollow inner cavity configuration.

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.

An in-stock compressed gas delivery assembly to deliver gas to an airsoft gun, including a cartridge receiving portion to receive at least a portion of a compressed fluid cartridge, a locking cap to secure the compressed fluid cartridge in the gas delivery assembly, a puncture pin assembly to puncture a nozzle of the compressed fluid cartridge when the locking cap is closed over the cartridge, a regulator to regulate a volume of gas passing from the gas delivery assembly, and a plurality of expansion chambers configured to form a tortuous path, between the cartridge and the regulator, to expand liquid from the compressed fluid cartridge to gas, and a buffer tube having a first end configured to be coupled to the airsoft gun; and a second end configured to receive the gas delivery assembly such that the buffer tube houses at least a portion of the gas delivery assembly.
