Abstract: An effervescent liquid dispenser includes a dispenser body adapted for connection to a container containing pressurized effervescent liquid to be dispensed from the container, the dispenser including a fluid shaft in a passageway and a valve member, the fluid shaft being arranged along a length of the passageway, the fluid shaft and valve member being adapted to release the pressurized effervescent liquid upon urging of the valve member into an open position. A regulator connected to the dispenser body and in fluid communication with the container and the pressurized effervescent liquid, the regulator and the dispenser body being configured as a unitary assembly permitting selective passage of the pressurized effervescent liquid. A tube connected to the dispenser body and extending into the container, a spout connected to the dispenser body for discharging pressurized effervescent liquid, and the liquid dispenser is permanently affixed to the container and the container is non-refillable.

Abstract: A container is disclosed including an effervescent liquid and an effervescent liquid dispenser including pressurized gas from a pressurized gas source, and a regulator in selective fluid communication with the container and the pressurized gas source. In response to a differential pressure applied to the regulator being less than a first threshold value between a container pressure and an environmental pressure of an environment surrounding the dispenser, pressurized gas from the pressurized gas source is permitted to flow into the regulator chamber and the container until the first threshold value is achieved. In response to the differential pressure applied to the regulator being greater than the first threshold value between the container pressure and the environmental pressure, pressurized gas from the pressurized gas source is prevented from flowing into the regulator chamber and the container and in which the liquid dispenser is permanently affixed to the container.
