Effervescent liquid dispenser

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.

What is claimed is: 
     
         1 . An effervescent liquid dispenser comprising:
 a dispenser body;   wherein the dispenser is 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; and   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 that permits 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 the pressurized effervescent liquid;   wherein 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 effervescent is permitted to flow into the regulator chamber and the container until the first threshold value is achieved;   wherein 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 effervescent liquid is prevented from flowing into the regulator chamber and the container;   wherein the liquid dispenser is permanently affixed to the container and the container is non-refillable.   
     
     
         2 . The dispenser of  claim 1  further comprising a pressure relief valve spaced apart from the regulator, the pressure relief valve having a valve member in fluid communication with the container on one side of the valve member and in fluid communication with an environment surrounding the dispenser on the other side of the valve member;
 wherein in response to a first force applied to the container-facing side of the valve member exceeding a second force applied to the environment-facing side of the valve member, the valve member is actuated to an open position for discharging pressurized effervescent liquid from the container into the environment; 
 wherein in response to the first force applied to the container-facing side of the valve member being less than the second force applied to the environment-facing side of the valve member, the valve member is actuated to a closed position for preventing pressurized effervescent liquid discharge from the container into the environment. 
 
     
     
         3 . The container of  claim 1  wherein the pressurized effervescent liquid comprises a carbonated alcoholic beverage. 
     
     
         4 . The container of  claim 1  wherein the container complies with 27 C.F.R. 5.46 (2017). 
     
     
         5 . The container of  claim 4  wherein the container conforms with 49 C.F.R. 173.306 (2017). 
     
     
         6 . The container of  claim 1  wherein the tube comprises a flexible tube. 
     
     
         7 . The container of  claim 1  wherein the liquid dispenser is permanently affixed by compression fit. 
     
     
         8 . The container of  claim 1  wherein the liquid dispenser is permanently affixed by a crimp fit. 
     
     
         9 . The container of  claim 1  wherein the pressure within the container ranges from about zero to about 300 psi. 
     
     
         10 . The container of  claim 1  wherein a shaft extends through the dispenser and movement of the shaft permits pressurized effervescent liquid to flow which forces the pressurized effervescent liquid into the tube that in turn permits the pressurized effervescent liquid to pass through the dispenser body and be dispensed from the spout. 
     
     
         11 . The container of  claim 1  further comprising a tap wherein movement of the shaft is caused by rotational movement of the tap. 
     
     
         12 . The dispenser of  claim 1  wherein the regulator and the pressurized effervescent liquid are in continuous fluid communication. 
     
     
         13 . The container of  claim 1  wherein a cap having outwardly extending portions is affixed to the container and wherein the dispenser defines a groove and wherein the dispenser is permanently affixed to the container by engaging the portions and the groove. 
     
     
         14 . The container of  claim 1  wherein the container has a capacity of greater than 200 ml and the headspace above the effervescent liquid is less than 8 percent of the total capacity. 
     
     
         15 . The container of  claim 1  wherein a clevis having outwardly extending portions is affixed to the container and wherein the effervescent liquid dispenser defines a groove and wherein the dispenser is permanently affixed to the container by engaging the portions and the groove.
