A pressurized gas container associates with and supplies gas to a pressurized gas port of an appliance, such as for supplying carbon dioxide for the preparation of a carbonated drink. The container has a plug at its opening that has a barrier element that seals the container and is configured to be non-reversibly ruptured by a shaft of a gas-channeling member. The plug also has one or more sealing elements that are distinct from the barrier element and are configured for forming a gas-tight association with the shaft of the gas-channeling member. A plurality of such pressurized containers may be carried by a holder rack in a multipack. An appliance adapted for preparing or dispensing carbonated drink includes an adapter for associating with such a pressurized carbon dioxide-containing canister and for receiving the pressurized carbon dioxide therefrom.

A flavorant container for use in a beverage system is provided. The flavorant container can be retained by a beverage system to dispense flavorant, which can be mixed with carbonated and/or uncarbonated water. In one embodiment, the flavorant container includes a container, a cap, and one or more features located on the cap. The features can include an inlet that is able to receive pressurized air, and an outlet that is able to dispense a flavorant when the inlet receives the pressurized air. The features can also include at least one raised protrusion that is capable of being retained by a complimentary pattern located on a beverage system in order to properly seat the flavorant container in the beverage system.

A pressurized beverage dispenser having a beverage container and a cap. The cap includes a cap body, a compressed-gas cartridge, an external straw, a discharge chamber, a metering valve, a diaphragm, and an actuator. The discharge chamber within the cap body is in fluid communication with an internal passageway of the external straw. The metering valve allows a flow of beverage from the beverage container to the discharge chamber when the metering valve is open and substantially precludes the flow of beverage when the metering valve is closed. The diaphragm opens the metering valve when the diaphragm is activated and closes the metering valve when the diaphragm is deactivated. The diaphragm also activates when a user sucks on the outlet end of the external straw to create suction within the discharge chamber. The actuator on the cap body activates the diaphragm when the user manually engages the actuator.

A fluid pressurization and dispensing system, including a coupler releasably attached to a vessel via an attachment means for securing a vacuum seal between the coupler and the vessel for maintaining pressure within the vessel, refreshing the gas composition within the vessel, and dispensing of a fluid contents externally from within the vessel without disturbing the vacuum seal. The coupler has a rigid single body unit having a tap head, a shank, and a cap which are contiguous thereof the coupler including a plurality of channels each integrally machined within an interior portion of the coupler. The system regulates a flow of gas from a pressurized gas cartridge via a gas pressure regulator, enables venting excess gas via a gas pressure relief valve, enables measurement of gas pressure within the vessel via a gas pressure gauge. Another embodiment of the system includes a coupler including a bi-level tap head.

An adapter for an airtight connection to a container and for airtight dispensing of the container's contents, the adapter having: a gate valve, a tube extending from the gate valve to a female coupling, the female coupling being configured for insertion in a mouth of the container, the female coupling having a dispensing valve for opening when dispensing the container's contents and closing when dispensing is finished as needed, such that air is prevented from entering the container, and an airtight connector for connecting the adapter to the container.

The invention includes a vessel comprised of a rectilinear primary casing made from a polymer material and a removable dispenser and methods of dispensing and filling and cleaning the vessel. The vessel further includes a one-way valve that may be used to introduce gases to the vessel once the dispenser is attached and sealed to the primary casing, an optional integrated handle and optional integrated feet.

A receptacle for storing, pressurizing, and dispensing packaged beverages. The receptacle includes an airtight chamber with a removable lid, wherein the joint between the lid and the chamber is also airtight. A gas valve allows for the inflow and outflow of gas, and a tap port and tap stem allow the beverage to be dispensed without breaking the seal of the chamber. A pressure relief valve allows for more rapid depressurization. The chamber can be used at high and low pressures, such as a partial vacuum, to prevent oxidation of a number of open beverages, such as beers, wines, and sodas. A pressure gauge port coupled with an optional pressure gauge allows a user to verify the appropriate pressure for the type of beverage being preserved. The gas valve may be disposed on a base of the receptacle, as may the pressure relief and/or the pressure gauge port.

A container comprising a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting a liquid to or from the container after the friction seal is established between the female and male couplings.

Beverage dispensing system, beverage container and pressurizing system for use in a beverage dispensing system or container. Beverage dispensing system 1 comprising a beverage container 2 with a beverage compartment 3 and a pressurizing system 10, wherein the pressurizing system 10 comprises a gas container 11 comprising pressurized gas, a closure 13 closing the gas container 11 and a pressure regulator 12 operative for opening the closure 13 for allowing gas to enter into the beverage compartment 3 from the gas container 11, wherein the pressure regulator 12 comprises a regulating chamber 15 having at least a wall part 17 movable and/or deformable based on pressure in the beverage compartment 3, wherein at least one opening 24 is provided through a wall 18 of the regulating chamber 15 providing for at least part of a gas passage between the regulating chamber 15 and the beverage compartment 3.

A fluid pressurization and dispensing system, including a coupler releasably attached to a vessel via an attachment means for securing a vacuum seal between the coupler and the vessel for maintaining pressure within the vessel, refreshing the gas composition within the vessel, and dispensing of a fluid contents externally from within the vessel without disturbing the vacuum seal. The coupler has a rigid single body unit having a tap head, a shank, and a cap which are contiguous thereof the coupler including a plurality of channels each integrally machined within an interior portion of the coupler. The system regulates a flow of gas from a pressurized gas cartridge via a gas pressure regulator, enables venting excess gas via a gas pressure relief valve, enables measurement of gas pressure within the vessel via a gas pressure gauge.
