Device for preventing unauthorized tampering of container caps

Abstract

A device to prevent unauthorized tampering with container caps, comprising a protective hood including coupling elements for coupling the device to the neck of the container, and an adjustment mechanism for adjusting the hood on the neck and a tamper-proof locking mechanism of the adjustment mechanism.

1 . A device for preventing unauthorized tampering with a container cap, comprising: 
 a protective hood for the cap, the hood including coupling elements for coupling the hood to a neck of the container; the coupling elements include an adjustment mechanism for adjusting the coupling elements on the neck of the container; and    a tamper-proof locking mechanism operable on the adjustment mechanism for locking or unlocking the coupling elements on the neck.    
   
   
       2 . A device according to  claim 1 , wherein the hood defines a cover which covers the container cap and the cover axially extends from the free edge of a wall thereof in a series of strips, end portions of the strip have the coupling elements thereon for coupling to the neck of the container.  
   
   
       3 . A device according to  claim 2 , wherein the coupling elements comprise an adjustable clamp, and the adjustment mechanism coupling a worm screw which meshes with a toothed end portion of the clamp.  
   
   
       4 . A device according to  claim 2 , wherein the strips into which the wall of the hood extend have end portions finished in a passage located at the same height on all the strips, the passage enabling passage therethrough of the strip forming the clamp.  
   
   
       5 . A device according to  claim 1 , wherein the locking mechanism of the adjustment mechanism comprises a combination lock having a locking position that acts upon a non-return mechanism of the adjustment mechanism for preventing the actuation of the adjustment mechanism in the clamp release or opening direction.  
   
   
       6 . A device according to  claim 5 , wherein the non-return mechanism comprises a stop attached to the shaft of the closing mechanism, and in the locking position thereof, the stop acts against an attached catch of the shaft of the adjustment mechanism.  
   
   
       7 . A device according to  claim 1 , wherein the coupling elements comprise an adjustable clamp and the adjustment mechanism comprising a worm screw which meshes with a toothed end portion of the clamp.
