BOTTLE VALVE INSERT

摘要

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.

1. A bottle valve insert, comprising:
a flapper valve and a base insert; the flapper valve portion comprising an attachment lip and a flapper seal; the attachment lip comprising a generally flat annular extension of the flapper seal; the flapper seal extending downwards from the attachment lip into the base insert and transitioning inwards and upwards towards a dome seat; the flapper seal contacting the dome seat and adapted to form a first seal with the dome seat; a fluid dispensing port in the flapper seal allowing a fluid to pass through the flapper seal when the first seal is broken; the base insert comprising a retention lip, a sidewall, and a base, wherein the retention lip is adapted to fit over a mouth of a beverage bottle; the attachment lip adapted to fit over the retention lip and form a second seal therewith; the sidewall attaching to the attachment lip, and extending downwards therefrom; the base extending inwards from the sidewall and attached thereto; the base comprising a plurality of support members and the dome seat; the plurality of support members extending radially inwards towards the dome seat, each support member having a distal end and a proximal end and wherein the distal end is attached to the dome seat; and wherein the dome seat is a dome-shaped member extending upwards from the plurality of support members through the fluid dispensing port in the flapper seal.
