Closing Element

Abstract

A closure element for bottles includes a stopper that engages in the mouth of a bottle, a head having a larger outside diameter than the stopper, a sealing element arranged in a transition region between stopper and head. The sealing element has a first sealing region which bears against the stopper and comprises at least one outwardly pointing sealing bead. The first sealing region has at least one outwardly pointing projection or at least one annular bead which is arranged at a distance from the annular sealing bead and on that side of the sealing bead which faces away from the head. The projection or at least one annular bead has at least one cutout introduced into the circumferential surface of the bead.

1 . A closure element for a bottle comprising: 
 a stopper engaging in a mouth of the bottle, the stopper having a head having a larger outside diameter than a diameter of the stopper;    a sealing element arranged in a transition region between the stopper and the head, the sealing element having a first sealing region which bears against the stopper and comprises at least one outwardly pointing sealing bead, the first sealing region having at least one outwardly pointing projection or at least one annular bead which is arranged at a distance from the sealing bead on that side of the sealing bead which faces away from the head, the annular bead having at least one cutout introduced into the a circumferential surface of the annular bead; and the first sealing region has at least one projection, on an inner side thereof which faces the stopper.    
   
   
       2 . The closure element as claimed in  claim 1 , wherein the sealing element has a second sealing region which bears against the head and which adjoins the first sealing region.  
   
   
       3 . The closure element as claimed in  claim 1 , wherein the sealing element is in a single piece.  
   
   
       4 . The closure element as claimed in  claim 1 , wherein the at least one projection comprises an inner bead on the sealing element and located further from the head than the sealing bead and nearer to the head than the annular bead.  
   
   
       5 . The closure element as claimed in  claim 1 , wherein the sealing element is composed of plastic.  
   
   
       6 . The closure element as claimed in  claim 1 , wherein the stopper is composed of glass.  
   
   
       7 . The closure element as claimed in  claim 1 , wherein the stopper is composed of at least one of metal, ceramic and plastic.  
   
   
       8 . The closure element as claimed in  claim 1 , wherein the at least one projection is an inner bead.
