Mechanical pressure relief valve for use in live beverages
A pressure actuated pressure relief valve is disposed in the body of a beverage vessel and is configured to be in fluidic communication with an exterior of the beverage vessel and an interior of the beverage vessel. The pressure actuated pressure relief valve being configured to actuate from a closed position to an open position based on pressure reaching a threshold within the interior of the beverage vessel. The pressure actuated pressure relief valve being configured to actuate from the open position to the closed position based on pressure falling below the threshold within the interior of the beverage vessel.
1. A can lid configured to seal a live beverage within an interior of a can, the can lid comprising:
a mouth opening formed through a can lid surface;
an obstruction configured to temporarily fill the mouth opening;
a tab that is attached to the can lid surface and is configured to facilitate a removal of the obstruction from the mouth opening;
a pressure relief opening formed through the can lid surface;
a pressure actuated relief valve disposed within the pressure relief opening, the pressure actuated relief valve comprising:
a biasing mechanism that biases the pressure actuated relief valve toward a valve closed position, the pressure actuated relief valve being configured to counteract the biasing mechanism and drive a movement of the pressure actuated relief valve to a valve open position in response to pressure from of a volume of gas produced by the live beverage reaching a pressure threshold, and wherein the biasing mechanism returns the pressure actuated relief valve to the closed position in response to the pressure falling below the threshold.
2. The can lid of claim 1 , wherein a portion of the pressure actuated relief valve is positioned on both sides of the can lid surface when the pressure actuated relieve valve is disposed within the pressure relief opening.
3. The can lid of claim 1 , wherein the can lid is an aluminum can top.
4. The can lid of claim 1 , wherein the can lid further comprises a can rim that circumferentially surrounds the can lid surface on all sides such that the can lid rim and the can lid surface are within a common plane.
5. The can lid of claim 1 , wherein the tab is connected to the can lid surface utilizing a can lid rivet.
6. The can lid of claim 1 , wherein the can lid surface, a can lid rim, and at least a portion of the pressure relief valve are all positioned within a common plane.
7. The can lid claim 1 , wherein the can lid further comprises a can lid rim, the pressure release valve being configured to extend from the can lid surface a distance that is less than a distance that the lid rim extends from the can lid surface.
8. The can lid of claim 1 , wherein the pressure actuated relief valve further includes a tamper feature.
9. The can lid of claim 1 , wherein the pressure actuated relief valve further includes a valve cap.
