Abstract
A bottle valve has a flapper valve and a base insert. The base insert can be pressure fit into the mouth of a beverage bottle. The insert has support members that extend from a sidewall towards the center. At the convergence of the support members is a dome seat. The flapper valve rests atop and inside the base insert and has a dispensing port. The port fits over the dome seat and presses against it to form a seal. When pressure is applied to the bottle, it is deformed and the liquid therein is forced to flow between the support members, pushing the flexible flapper seal away from the dome seat and allowing the liquid to flow out of the bottle mouth. When the pressure is relieved, the flapper seal returns to its rest position against the dome seat, reforming the seal and stopping air from flowing into the bottle.
