Container with seal assurance means

Abstract

The container ( 1 ) which can be sealed in a tamper-proof manner by a seal assurance means ( 5 ) has an outwardly projecting opening edge ( 2 ) and connected to the opening edge with sealing contact a cover ( 3 ) which is connected to the container ( 1 ) by the seal assurance means ( 5 ) in such a manner that non-destructive release is impossible. The seal assurance means ( 5 ) is formed on one side by a retaining ring ( 6 ) which encircles the container ( 1 ) below its opening edge ( 2 ) and on the other side by a cover part ( 7 ) which covers over the cover ( 3 ) of the container ( 1 ) at least partially. The retaining ring ( 6 ) is hingedly connected to the cover part ( 7 ) of the seal assurance means and at at least one area across the container and opposite the hinge connection ( 8, 9 ) there are, mutually engaging in such a manner that non-destructive release is impossible, locking means ( 10 - 13 ) which interlock the retaining ring ( 6 ) and the cover part ( 7 ) of the seal assurance means ( 5 ). Thus the cover ( 3 ) sealing the container ( 1 ) is sealed between them in such a manner that non-destructive release is impossible.

1 . Container with an outwardly projecting opening edge ( 2 ), a cover ( 3 ) connected to the opening edge with sealing contact, and a seal assurance means ( 5 ) which connects the cover to the container ( 1 ) in such a manner that non-destructive release is impossible, characterized in that the seal assurance means ( 5 ) comprises on one side a retaining ring ( 6 ) which encircles the container ( 1 ) below its opening edge ( 2 ) and on the other side a cover part ( 7 ) which covers over the cover ( 3 ) of the container ( 1 ) at least partially, where the retaining ring ( 6 ) is hingedly connected to the cover part ( 7 ) and at at least one area across the container and opposite the hinge connection ( 8 ,  9 ) comprises, engaging in such a manner that non-destructive release is impossible, locking means ( 10 - 13 ) which interlock the retaining ring ( 6 ) and the cover part ( 7 ) of the seal assurance means ( 5 ) so that they enclose the cover ( 3 ). 
     
     
         2 . Container according to  claim 1 , characterized in that the seal assurance means ( 5 ) is formed as one piece of plastic so that the hinge connection ( 8 ,  9 ) forms an integral hinge. 
     
     
         3 . Container according to  claim 2 , characterized in that the hinge connection is formed by at least two flexible bars ( 8 ,  9 ) connecting their retaining ring ( 6 ) to their cover part. 
     
     
         4 . Container according to  claim 1 , characterized in that the locking means of the seal assurance means ( 5 ) consist of at least one locking shank ( 10 ,  11 ) and at least one corresponding locking collet ( 12 ,  13 ) which on one side are formed on the retaining ring ( 6 ) and on the other side are formed on the cover part ( 7 ). 
     
     
         5 . Container according to  claim 4 , characterized in that the at least one locking collet ( 12 ,  13 ) is open on both sides and has inner profiling tapering conically in the direction of locking engagement and ending in a lock shoulder ( 15 ). 
     
     
         6 . Container according to  claim 5 , characterized in that the at least one locking shank ( 10 ,  11 ) is embodied as a hollow dowel ( 16 ) formed on the cover part ( 7 ) and insertable into a locking collet ( 12 ,  13 ), said hollow dowel having, on a part of its peripheral face and forming a shoulder, a nose-like cross section by which a locking detent  17  is formed. 
     
     
         7 . Container according to  claim 6 , characterized in that the dowel ( 16 ) of the locking shank ( 10 ,  11 ) forms a downwardly open hollow body.
