Bottle closure device

Abstract

The closure device (D) for closing a bottle ( 1 ) comprises an overmolded cap ( 2 ) and ferrule ( 4 ) made of two different materials and prevented from moving relative to each other by tamperproofing means ( 43 ). The device (D) further comprises fastener means ( 3, 5 ) for fastening onto the neck ( 11 ) of the bottle. A first element selected from the cap ( 2 ) and the ferrule ( 4 ) includes a peripheral tongue ( 43 ) that is placed substantially around the entire outer periphery of the device (D) and that forms the tamperproofing means. This tongue is connected to a body ( 41 ) of the first element via tearable means ( 45 ) and includes patterns ( 47 ) designed to co-operate, while the tongue is connected to the body of the first element, with complementary patterns ( 27 ) formed in the second element selected from the cap ( 2 ) and the ferrule ( 4 ).

1 - 10 . (canceled) 
   
   
       11 . A device for closing a bottle, the device comprising:
 an overmolded cap and ferrule made of two different materials and prevented from moving relative to each other by tamperproofing means, and   fastener means for fastening to a neck of the bottle,   wherein a first element selected from the cap and the ferrule includes a peripheral tongue that is placed around substantially the entire outer periphery of the device and that forms said tamperproofing means, said tongue being connected to a body of said first element via tearable means and including patterns that are designed, when the tongue is connected to the body of said first element, to co-operate with complementary patterns formed in the second element selected from the cap and the ferrule.   
   
   
       12 . A closure device according to claim  1 , wherein the material constituting the cap is not adhesive relative to the material constituting the ferrule. 
   
   
       13 . A closure device according to claim  1 , wherein said tearable means comprise tear serrations. 
   
   
       14 . A closure device according to claim  1 , wherein the tongue is connected to a body of the ferrule, said body being designed to surrounding the neck of the bottle. 
   
   
       15 . A closure device according to claim  4 , wherein the tongue covers the cap in part and includes indented patterns in its inner peripheral surface, which patterns are substantially complementary to complementary patterns in relief formed on the outer peripheral surface of the cap. 
   
   
       16 . A closure device according to claim  1 , wherein said fastener means comprise a fastener ring and a stopper suitable for being screwed onto said fastener ring, the cap and the stopper comprising complementary prevention means for preventing relative movement. 
   
   
       17 . A closure device according to claim  6 , wherein said prevention means comprise teeth projecting radially from the inner peripheral surface of the cap and substantially complementary to teeth projecting radially from the outer peripheral surface of the stopper. 
   
   
       18 . A closure device according to claim  6 , wherein the fastener ring includes means for preventing it from moving axially or in rotation relative to the neck of the bottle. 
   
   
       19 . A closure device according to claim  6 , wherein the fastener ring is connected to a pourer assembly. 
   
   
       20 . A closure device according to claim  1 , wherein the overmolded cap and ferrule are made by dual injection of two different synthetic materials.
