Metal bottle seal

Abstract

Disclosed is a metal bottle seal that is disposed on the curl of the metal bottle. The bottle seal may be held in place by crimping of the curl. In addition, adhesive may be used to hold the bottle seal on the curl. Adhesives can be used that fill discontinuities that may exist in the curl as a result of substantial drawing and ironing of the metal. Further, the metal bottle seal can be made of a material or laminated with a material that is soft enough to fill the discontinuities. The seal can be preformed as a continuous annulus for easy application to the top of the metal bottle. The metal bottle seal can also be used in conjunction with a cap seal to ensure an adequate and reliable seal.

1 . A sealing system comprising: 
 a bottle seal formed in the shape of an annulus that is made from a material suitable for creating a seal with a closure;    a metal bottle that is shaped to form a bottle neck, said bottle neck having a curl formed in an edge of said bottle neck, said curl formed in a crimped configuration that mechanically holds said bottle seal on said curl;    an adhesive disposed between said bottle seal and said curl that fills discontinuities in said curl and holds said bottle seal on said curl.    
   
   
       2 . The system of  claim 1  further comprising: 
 a cap;    a cap seal disposed in said cap that interfaces with said bottle seal to provide a hermetic seal between said cap and said metal bottle.    
   
   
       3 . The system of  claim 2  wherein said closure is a twist-off cap.  
   
   
       4 . The system of  claim 2  wherein said closure is a roll-on pilfer proof closure.  
   
   
       5 . The system of  claim 2  wherein said closure comprises a bottle crown.  
   
   
       6 . A method of sealing a metal bottle comprising: 
 providing a metal bottle having a curl formed in the upper edge of the metal bottle;    placing a bottle seal on said curl so that a portion of the bottle seal wraps around said curl;    crimping said curl to mechanically secure said bottle seal to said curl.    
   
   
       7 . The method of  claim 5  further comprising: 
 coating said bottle seal with an adhesive;    attaching said bottle seal to said curl with said adhesive such that said adhesive fills discontinuities in said curl.    
   
   
       8 . The method of  claim 6  further comprising: 
 providing a cap having a cap seal;    forming a compression seal between said cap seal and said bottle seal.    
   
   
       9 . A sealing system comprising: 
 a metal bottle that is shaped to form a bottle neck, said bottle neck having a curl formed in an edge of said bottle neck;    a bottle seal formed in the shape of an annulus that is made from a first layer that has a predetermined softness and a predetermined thickness that is sufficient to substantially fill discontinuities in said curl, and a second layer that is attached to said first layer that is made from a material suitable for creating a seal with a bottle cap, said bottle seal disposed between said curl and said metal bottle, said curl formed in a crimped configuration that mechanically holds said bottle seal on said curl.    
   
   
       10 . A sealing system comprising: 
 a metal bottle that is shaped to form a bottle neck, said bottle neck having a curl formed in an edge of said bottle neck;    a bottle seal formed in the shape of annulus that is made from a material that is suitable for creating a seal with a cap closure that is attached to said curl in said metal bottle.    
   
   
       11 . The sealing system of  claim 9  further comprising: 
 an adhesive disposed between said bottle seal and said curl that fills discontinuities in said curl and holds said bottle seal on said curl.    
   
   
       12 . The sealing system of  claim 9  wherein said bottle seal is made from a material that is self-adhering to said curl.
