Cap element for a beverage can

Abstract

The invention relates to a cap element adapted for being fixed to a container, which container comprises an upper surface that is bounded by an edge. The cap element comprises a one-piece, substantially rigid main cap that defines an interior space and at least one opening defined by a circumferential edge adapted to engage over the edge of the container so as to enclose at least part of the container, and sealing means in the interior space near the opening, within the circumferential edge of the main cap, which sealing means are adapted to engage against the upper surface of the container. At least one resilient fixing element is provided in the interior space near the opening, within the circumferential edge of the main cap, which resilient element is adapted to engage against or around the container edge.

1 . A cap element adapted for being fixed to a container, which container comprises an upper surface that is bounded by an edge, said cap element comprising: 
 a one-piece, substantially rigid main cap that defines an interior space and at least one opening defined by a circumferential edge adapted to engage over the edge of the container so as to enclose at least part of the container;    sealing means in the interior space near the opening, within the circumferential edge of the main cap, which sealing means are adapted to engage against the upper surface of the container;    at least one resilient fixing element in the interior space near the opening, within the circumferential edge of the main cap, which resilient element is adapted to engage over or around the container edge.    
     
     
         2 . The cap element according to  claim 1 , wherein the cap element is of circular section at least near the opening, and wherein the resilient element comprises a first ring-shaped element provided with resilient fixing tabs, which first ring-shaped element is arranged in the interior space of the main cap, near the opening.  
     
     
         3 . The cap element according to  claim 1 , wherein the cap element is of circular section at least near the opening, and wherein the resilient element comprises a first ring-shaped element provided with at least three substantially uniformly spaced resilient fixing tabs, which first ring-shaped element is arranged in the interior space of the main cap, near the opening.  
     
     
         4 . The cap element according to  claim 1 , wherein the cap element is of circular section at least near the opening, and wherein the resilient element comprises a first ring-shaped element provided with resilient fixing tabs and wherein the cap element further comprises a second ring-shaped element provided with openings, which second ring-shaped element is fitted in the interior space of the main cap, and wherein the fixing tabs extend through the openings of the second ring-shaped element in the direction of the opening of the main cap.  
     
     
         5 . The cap element according  claim 1 , wherein the cap element is of circular section at least near the opening and wherein the sealing means comprise a third ring-shaped, deformable element.  
     
     
         6 . The cap element according to  claim 1 , wherein the main cap, the sealing means and the resilient element are in one piece.  
     
     
         7 . The cap element according to  claim 1 , wherein the main cap comprises a further opening that is in communication with said opening via the interior space.  
     
     
         8 . The cap element according to  claim 1 , wherein the cap element is arranged in such a manner that said further opening cannot be closed.  
     
     
         9 . The cap element according to  claim 1 , wherein the cap element comprises means for attaching carrying means thereto.  
     
     
         10 . The cap element according to  claim 1 , wherein the cap element can be fixed to a soft drink container.  
     
     
         11 . The cap element according to  claim 1 , wherein the resilient element is adapted for detachably fixing the cap element to the container.  
     
     
         12 . A cap element adapted for being fixed to a beverage container, which container comprises a surface provided with a removable element for opening the container and a groove bounded by an edge, said cap element comprising: 
 a main cap provided with an opening;    a first ring-shaped element provided with three or more resilient fixing tabs, which is arranged in the main cap to engage over or around the container edge;    a second ring-shaped element fitted in the main cap, which is provided with openings through which the fixing tabs extend in the direction of the opening of the main cap; and    a third ring-shaped element fitted to the second ring-shaped element, which is adapted to be positioned in said groove in a substantially leak-proof manner.    
     
     
         13 . A cap element adapted for being fixed to a beverage container, which container comprises a surface provided with a removable element for opening the container, said cap element comprising: 
 a rigid main cap provided with an opening;    a ring-shaped element in the main cap, which is provided with at least three resilient fixing tabs that are adapted to effect a snap connection with the container edge without deformation of the main cap being required.
