Abstract

A bottle closure is disclosed to include a muzzle fastened to and covered on the bottle neck of a bottle, a cap hinged to the periphery of the muzzle for closing on the muzzle to seal the bottle neck of the bottle, the cap having an operating structure for gripping by the user's hand to turn the cap relative to the muzzle between a close position and an open position, and a seal tearably connected to the muzzle to seal the operating structure of the cap.

1 . A bottle closure comprising: 
 a muzzle connectable to the bottleneck of a bottle;    a cap hinged to the periphery of said muzzle for closing on said muzzle to seal the bottle neck of the bottle to which said muzzle is fastened, said cap comprising an operating structure for gripping by the user's hand to turn said cap relative to said muzzle between a close position and an open position; and    a seal tearably connected to said muzzle to seal said operating structure of said cap.    
   
   
       2 . The bottle closure as claimed in  claim 1 , wherein said muzzle has a spout at a top side thereof.  
   
   
       3 . The bottle closure as claimed in  claim 2 , wherein said cap comprises a downwardly suspended bottom plug adapted to seal said spout of said muzzle.  
   
   
       4 . The bottle closure as claimed in  claim 1 , wherein said muzzle comprises a flat circular top protrusion, and a recessed portion formed in the periphery of said flat circular top protrusion.  
   
   
       5 . The bottle closure as claimed in  claim 4 , wherein said cap comprises a vertical peripheral wall fitting over the periphery of said flat circular top protrusion of said muzzle.  
   
   
       6 . The bottle closure as claimed in  claim 1 , wherein said operating structure of said cap comprises a recessed portion adapted to receive said seal.  
   
   
       7 . The bottle closure as claimed in  claim 6 , wherein said seal has a bevel at one end thereof corresponding to one end of the recessed portion of said operating structure.  
   
   
       8 . The bottle closure as claimed in  claim 6 , wherein said operating structure of said cap comprises a retaining block protruded from the recessed portion thereof for engaging said seal.  
   
   
       9 . The bottle closure as claimed in  claim 8 , wherein said seal comprises a retaining notch adapted to receive the retaining block of said operating structure of said cap.  
   
   
       10 . The bottle closure as claimed in  claim 6 , wherein said operating structure of said cap comprises two bevels at two ends of the recessed portion thereof.  
   
   
       11 . The bottle closure as claimed in  claim 1 , wherein said seal comprises a seal body tearably connected to the periphery of said muzzle, and a finger strip extended from one end of said seal body.  
   
   
       12 . The bottle closure as claimed in  claim 1 , wherein said seal comprises a thin connecting portion tearably connected to the periphery of said muzzle.  
   
   
       13 . The bottle closure as claimed in  claim 12 , wherein said thin connecting portion is serrated.  
   
   
       14 . The bottle closure as claimed in  claim 12 , wherein said thin connecting portion is perforated.
