Capsule for bottlenecks formed by an adhesive disc and heat-shrinkable sleeve, a process for in-line inclusion of said capsule line, and a machine for forming said capsule by said process

Abstract

A capsule for bottle necks ( 2 ) consisting of: an adhesive disc ( 1 ) arranged on the upper part of the bottle neck ( 2 ); a sleeve made of a heat-shrinkable material ( 3 ), having a cylindrical shape and an initial diameter larger than that of the bottle neck ( 2 ).

1 . A capsule for bottle necks comprising:
 an adhesive disc arranged on the upper part of said bottle neck;   a sleeve made of a heat-shrinkable material, having a cylindrical shape and an initial diameter larger than that of said bottle neck.   
     
     
         2 . The capsule according to  claim 1 , wherein said adhesive disc is arranged on a silicone substrate thus forming a web, and wherein said adhesive has an adhesive base to be placed on the upper part of the bottle neck on a cork. 
     
     
         3 . The capsule according to  claim 1 , wherein said sleeve is made of a heat-shrinkable material such as PVC. 
     
     
         4 . The capsule according to  claim 1 , wherein said sleeve is obtained from a web that is specifically formed as a tube by register cutting at predefined zones, whereby a printing zone is defined in between. 
     
     
         5 . A process for in-line inclusion of a capsule according to  claim 1 , wherein said process includes the steps of:
 applying, by means of an adhesive-disc applicator, said adhesive discs on bottle corks;   applying, by means of a sleeve applicator, heat-shrinkable sleeves around the bottle neck;   applying heat, by means of an electrical tunnel arranged on the bottle neck, to said sleeves and shrinking them so that they wrap both the neck of one of the bottles, and a part of said adhesive disc, thus leaving the core of said adhesive disc free, whereby said capsule is formed.   
     
     
         6 . The process according to  claim 5 , wherein said applicator unwinds and places the tube of a web on a bullet that renders it open, and gives it the shape of a cylindrical sleeve, this sleeve being cut by using a cutting blade system so as to be mechanically positioned on the bottle neck, by means of rolls that move the sleeve so as to place the sleeve into position. 
     
     
         7 . A machine to form the capsule according to  claim 1 , using the process according to  claim 5 , the machine comprising:
 a conveyor belt on which said bottles are vertically laid on their base as they move forward;   a first station including an adhesive-disc applicator placing those disc on bottle cork “C”, and of an adhesive-disc substrate collector;   a second station including a sleeve applicator that wraps a heat-shrinkable sleeve around the bottle neck;   a third station including an electrical tunnel arranged on the bottle neck, wherein said capsule is formed.   
     
     
         8 . The machine according to  claim 7 , wherein said sleeve applicator includes a cutting blade system to cut said sleeves, and a roll system to move said sleeves so as to place them into their position on said bottle neck.
