Closure assembly for beverage cans

Abstract

A closure assembly, specifically designed for beverage cans, comprises a tang pivoted to a pivot pin rigid with a wall of the can at an opening portion, which can be removed for freeing an opening therefrom it is possible to pour the cap contents, or directly drink the beverage, and being characterized in that the tang, pivoted to a pin rigid with the can wall, comprises an enlarged thickness portion, designed for reclosing the opening of the can.

1 . A closure assembly, for beverage cans, characterized in that said closure assembly comprises a closure tang pivoted to a pivot pin rigid with a wall of a can, at an opening portion thereof and which can be removed for freeing an opening therefrom it would be possible to pour the beverage of said can or directly drink it, characterized in that said tang comprises an increased thickness portion, and adapted to reclose said opening.  
     
     
         2 . A closure assembly, according to  claim 1 , characterized in that said increased thickness portion is formed on a bottom surface of said tang.  
     
     
         3 . A closure assembly, according to  claim 1 , characterized in that said tang is made of a plastic material.  
     
     
         4 . A closure assembly, according to  claim 1 , characterized in that said increased thickness portion has a mushroom configuration.  
     
     
         5 . A closure assembly, according to  claim 1 , characterized in that said tang comprises a gripping and driving projecting edge.  
     
     
         6 . A closure assembly, according to  claim 1 , characterized in that said increased thickness portion is formed on a bottom surface of said tang, said tang being adapted to reclose the opening of said can, and to rotate through an angle of 180° with respect to a starting position thereof used for lever-pressing on a weakened portion as said can is opened.  
     
     
         7 . A closure assembly, according to claim  1 , characterized in that said tang has a sufficient stiffness to be used for opening said weakened portion, while having resilient properties to allow said increased thickness portion to resiliently engage the edges of said opening.  
     
     
         8 . A closure assembly, according to  claim 1 , characterized in that said increased thickness portion has a mushroom configuration, so as to be firmly engaged in said opening.  
     
     
         9 . A closure assembly, according to  claim 1 , characterized in that said closure assembly comprises a raised-projecting edge for facilitating the reopening of said can, while allowing said tang to turn in order to free again said opening.
