Stopper for a bottle pourer

Abstract

A stopper for a bottle pourer includes a shaft tapering from a wide end to a narrow end, the shaft having a substantially straight portion from the narrow end to a midpoint of the shaft and having a curved portion from the midpoint to the wide end and a head attached to the wide end.

1 . A stopper for a bottle pourer, the stopper comprising: 
 a shaft tapering from a wide end to a narrow end, the shaft having a substantially straight portion from the narrow end to a midpoint of the shaft and having a curved portion from the midpoint to the wide end; and    a head attached to the wide end.    
   
   
       2 . The stopper of  claim 1 , wherein the shaft comprises a circular cross-section.  
   
   
       3 . The stopper of  claim 1 , wherein the shaft comprises an oval cross-section.  
   
   
       4 . The stopper of  claim 1 , wherein the curved portion comprises an increasing radius of curvature from the midpoint to the wide end.  
   
   
       5 . The stopper of  claim 1 , wherein the curved portion comprises a curved portion configured to position a central axis of the head at an angle of 30° relative to a central axis of the straight portion.  
   
   
       6 . The stopper of  claim 1 , wherein the stopper comprises a resilient elastomeric material.  
   
   
       7 . The stopper of  claim 1 , wherein the head comprises a circular disc.  
   
   
       8 . The stopper of  claim 1 , wherein the head comprises a sphere.  
   
   
       9 . A liquid pouring system for a bottle, comprising: 
 a liquid pourer having a base, a spout extending from the base at an arcuate angle relative to a central axis of the base, and a central bore through the base and the spout defining a channel;    an elongated stem having a wide end tapering to a narrow end, the stem having a substantially straight portion from the narrow end to a midpoint of the stem and an arcuate portion with a radius of curvature about equal to the radius of curvature of the arcuate angle of the spout the, stem being insertable into the channel thereby sealing the channel.
