Container closure

Abstract

The invention relates to a container closure in which a closure spigot ( 3 ), which is inserted in the area of the continuous opening of the closure, is provided on the part ( 1 ) that is placed on or inserted in the container mouth. A closure cap ( 5 ), which can be slid onto the part that is placed on or inserted and which comprises an outlet opening ( 6 ) corresponding in shape and size to the cross-section of the closure spigot ( 3 ), can be tightly slid onto said closure spigot. In a closed position, the closure cap is held on the part that is placed on or inserted in the container mouth by means of a collar ( 8 ), which closely surrounds said part. In addition, a covering cap ( 14 ) is provided which accommodates the closure cap and which is joined to a ring ( 16 ) via desired rupture points ( 18 ). Said ring is held on an annular collar ( 15 ), which is provided on the part that is placed on or inserted in the container mouth, and which outwardly projects in an axial direction. The free edge of the covering cap ( 14 ) facing the part ( 1 ) that can be placed on or inserted in the container comprises a circumferential sealing surface ( 19, 19 ′) that is appointed for resting on the free, outwardly pointing edge of the annular collar ( 15 ).

1 . Container closure, wherein a closure spigot which is inserted in the area of the through opening of the closure device, is provided on the part that is placed on or inserted in the container mouth, wherein a closure cap which can be slid onto the part that is placed on or inserted in the container mouth and which has an exit opening corresponding in form and size to the cross-section of the closure spigot can be sealingly pushed on the closure spigot, wherein in a closed position the closure cap is held by a collar which tightly surrounds the part that is placed on or inserted in the container mouth, and wherein a covering cap is provided which accommodates the closure cap and is connected to a ring via desired rupture points, which ring is held on an annular collar projecting outwardly in an axial direction and provided on the part placed on or inserted in the container mouth, characterized in that the covering cap ( 14 ) has on its free edge that faces the part placed on or inserted in the container, a circumferential sealing surface ( 19 ,  19 ′) intended for contacting the free outwardly projecting edge of the annular collar ( 15 ).  
     
     
         2 . Container closure according to  claim 1 , characterized in that the sealing surface ( 19 ) is formed as a sealing lip that can be bought in contact with the outer surface or marginal edge ( 20 ) of the annular collar ( 15 ) that faces the ring ( 16 ).  
     
     
         3 . Container closure according to  claim 2 , characterized in that the sealing lip ( 19 ) engages behind the outer surface ( 20 ) of the annular collar ( 15 ) in the form of a snap connection.  
     
     
         4 . Container closure according to  claim 2  or  3 , characterized in that the annular collar ( 15 ) and the ring ( 16 ) are provided with a serration ( 21 ) on the surfaces that face each other, wherein the serrations ( 21 ) engage with one another.
