Bottle seal

Abstract

The invention relates to a closure for closing a bottle having a bottleneck ( 1 ) with an opening on which bottleneck an outer thread ( 5,6 ) is formed in the vicinity of the opening. In order to provide a closure that is easy to handle and can be fabricated inexpensively, the closure ( 2 ) has at least one, and particularly several, deformation regions which are plastically deformed so that in the outer peripheral surface of the closure they form indentations ( 21,22 ) and internally ( 25,26 ) they are adapted to the thread ( 5,6 ).

1 . Closure for closing a bottle having a bottleneck with an opening on which bottleneck, in the vicinity of said opening, there is formed an outer thread, the closure having at least one and particularly several deformation regions that are plastically deformable so that in the outer peripheral surface of the closure they form indentations and internally they are adaptable to the thread, the deformation regions being elongated and disposable essentially parallel to the longitudinal axis of the bottle or at an angle to the thread and the closure having an outer jacket made of plastically deformable sheet metal, particularly aluminum, on the inside of which can be placed a plastically deformable sealing material, particularly a plastic material, wherein the deformation regions in the outer jacket are shaped in the form of elongated tongues or creases disposed in the direction of the longitudinal axis of the bottle and that in the deformation regions, on the inside of the closure, the sealing material can be pressed against the thread flights.  
   
   
       2 . Closure as defined in  claim 1 , wherein the jacket has the shape of a cap surrounding an essentially cylinder jacket-shaped body one face of which is closed by a circular disk-shaped lid.  
   
   
       3 . Closure as defined in  claim 2 , wherein the sealing material is disposed internally on the cylinder jacket-shaped body.  
   
   
       4 . Closure as defined in  claim 1 , wherein the sealing material is disposed in the region of the interface between the body and the lid.  
   
   
       5 . Closure as defined in  claim 1 , wherein the closure is combined with a safety element providing a tamper-evident closure.  
   
   
       6 . Bottle, particularly a beverage bottle, with a bottleneck having an opening on which bottleneck, in the vicinity of said opening, there is formed an outer thread, wherein the bottle opening is closed by a closure as defined in  claim 1 .  
   
   
       7 . Method for closing a bottle, particularly a beverage bottle, with a bottleneck having an opening, on which bottleneck, in the vicinity of said opening, there is formed an outer thread, with a closure as defined in  claim 1 , wherein the closure is placed on the bottleneck and the deformation regions are deformed plastically so that in the outer peripheral surface of the closure they form indentations and internally they are adapted to the bottle thread.  
   
   
       8 . Method as defined in  claim 7 , wherein the following steps: 
 a) first, applying pressure to the closure to ensure sealing between the closure and the bottleneck opening;    b) then, deforming the deformation regions of the closure.    
   
   
       9 . Device for closing a bottle, particularly a beverage bottle, with a bottleneck having an opening on which bottleneck, in the vicinity of said opening, there is formed an outer thread, with a closure as defined in  claim 1 , wherein form fingers intended for the purpose of forming the deformation regions.  
   
   
       10 . Device as defined in  claim 9 , wherein the form fingers are supported in swivelable manner.  
   
   
       11 . Device as defined in  claim 10 , wherein a conical sleeve intended for the purpose of pressing the form fingers against the deformation regions of the closure so as to bring about plastic deformation of the deformation regions.  
   
   
       12 . Device as defined in one  claim 9 , wherein a plunger intended for the purpose of applying pressure to the closure so as to press the closure against the bottle opening.  
   
   
       13 . Device as defined in  claim 12 , wherein the form fingers are disposed on the plunger in swivelable manner.  
   
   
       14 . Device as defined in  claim 12 , wherein the form fingers are held together by an elastic ring.  
   
   
       15 . Device as defined in  claim 14 , wherein each of the form fingers is provided with a recess for receiving a section of the elastic ring.  
   
   
       16 . Device as defined in  claim 9 , wherein in the end region of each of the form fingers there is provided a nose intended for the purpose of reshaping a safety element.  
   
   
       17 . Device as defined in  claim 9 , wherein the conical sleeve is displaceable relative to the plunger in the direction of the longitudinal axis of the plunger.
