Abstract

A champagne bottle opener designed to dislodge an overhanging top of closure of the type commonly used to close champagne or sparkling wine bottles. The device includes a handle and a bifurcated working area having a prying surface designed to engage the overhanging edge of the closure and deflect it sideward to begin its removal. In one embodiment the bifurcated working area includes a pair of arms which are spaced a distance greater than the bottle neck diameter and less than the diameter of the wire retaining ring around the neck of a champagne bottle. In another embodiment a single angular arm forms with the handle a recess for receiving the bottle neck. In still another embodiment the arms are bent to conform with the upper surface of the ring of the bottle. In normal use, the sideward movement of the cork is sufficient to cause its dislodgement from its sealed position and it may be easily removed manually or it may pop off in a controlled and predictable manner.
