Abstract

The present invention relates to a foil capsule, bottle, machine for making score lines in a foil capsule, and method for making score lines in a foil capsule. The foil capsule is made of a metal alloy that comprises at least 99.5% by weight of aluminum. The machine for making score lines in a foil capsule comprises a rotary element ( 30 ) configured for being inserted in the capsule such that the capsule rotates on a longitudinal axis of the capsule when the rotary element ( 30 ) rotates, and at least two cutting elements ( 31, 32 ), arranged to make the corresponding cutting lines as the rotary element rotates. The cutting elements ( 31, 32 ) are arranged in a mounting ( 33 ) configured such that it can rock in a plane about a pivoting axis ( 35 ), said longitudinal axis being perpendicular to said plane.

         6 . Machine according to  claim 5 , wherein said two cutting elements are arranged horizontally separated by a distance such that upon contacting the capsule assembled on the rotary element, said cutting elements contact said capsule on both sides of a plane of symmetry traversing the longitudinal axis of the capsule and the pivoting axis of the mounting. 
     
     
         7 . Machine according to  claim 5 , wherein said mounting is associated with a moving head the position of which determines the pressure that the cutting elements apply on the capsule. 
     
     
         8 . Machine according to any of  claim 5  wherein the cutting elements are rotating cutting elements. 
     
     
         9 . Machine according to any of  claim 5 , wherein the two cutting elements are located on opposite faces of the mounting. 
     
     
         10 . Method for making score lines in a foil capsule using a machine according to  claim 5  comprising the steps of:
 locating the capsule in the rotary element, 
 positioning the cutting elements such that they exert a specific force on the capsule; and 
 rotating the rotary element such that the cutting elements produce respective score lines. 
 
     
     
         11 . Bottle comprising a bottle body and a neck, the being closed by a stopper or by a cork, the bottle further comprising a foil capsule, characterized in that said foil capsule is a capsule according to  claim 2 . 
     
     
         12 . Bottle comprising a bottle body and a neck, the bottle being closed by a stopper or by a cork, the bottle further comprising a foil capsule, characterized in that said foil capsule is a capsule according to  claim 3 . 
     
     
         13 . Machine according to  claim 6 , wherein said mounting is associated with a moving head the position of which determines the pressure that the cutting elements apply on the capsule. 
     
     
         14 . Machine according to  claim 6  wherein the cutting elements are rotating cutting elements. 
     
     
         15 . Machine according to  claim 7  wherein the cutting elements are rotating cutting elements. 
     
     
         16 . Machine according to  claim 15  wherein the two cutting elements are located on opposite faces of the mounting.
