Packaging with subsequently molded form-fit connection

Abstract

The present invention relates to a packaging with a packaging trough, into which a packaging material can be filled and which is closed with a lid, whereby at least one form-fit connection connects the packaging trough with the lid and the connection comprises a first and a second connection means. Furthermore, the present invention relates to a method for the production of a packaging as well as a packaging machine.

1 . A packaging ( 1 ) with a packaging trough ( 2 ), into which a packaging material can be filled and which is closed with a lid ( 3 ), whereby at least one form-fit connection ( 4 ) connects the packaging trough ( 2 ) with the lid ( 3 ) and the connection ( 4 ) comprises a first and a second connection element ( 4 ′,  4 ″), characterized in that at least one connection element ( 4 ′,  4 ″) has been molded at least partially into the packaging ( 1 ) after the packaging trough ( 2 ) has been closed with the lid ( 3 ).  
     
     
         2 . The packaging according to  claim 1 , characterized in that both connection elements ( 4 ′,  4 ″) are molded into the packaging after the packaging trough ( 2 ) has been closed with the lid ( 3 ).  
     
     
         3 . The packaging according to  claim 1 , characterized in that the connection elements are groove ( 4 ′) and tongue ( 4 ″).  
     
     
         4 . The packaging according to  claim 1 , characterized in that the form closure increases the pull-off force of the lid ( 3 ) from the packaging trough ( 2 ).  
     
     
         5 . The packaging according to  claim 1 , characterized in that the connection ( 4 ) is arranged parallel to the direction of transport of the items of packaging in a packaging machine.  
     
     
         6 . The packaging according to  claim 1 , characterized in that it has at least two form-fit connections ( 4 ).  
     
     
         7 . The packaging according to  claim 1 , characterized in that the lid ( 3 ) and the packaging trough ( 2 ) are sealed to one another, preferably in a peelable manner.  
     
     
         8 . A method for producing a packaging ( 1 ) having a packaging trough ( 2 ) and a lid ( 3 ), whereby the packaging trough ( 2 ) is closed with the lid ( 3 ), characterized in that a form-fit connection ( 4 ), which connects the lid with the packaging trough, is then molded into the packaging.  
     
     
         9 . The method according to  claim 8 , characterized in that the connection ( 4 ) is molded into the packaging after the lid has been sealed to the packaging trough.  
     
     
         10 . The method according to  claim 1 , characterized in that the connections are preferably molded in transversely to the direction of conveying.  
     
     
         11 . The method according to  claim 1 , characterized in that the connections are molded in with an embossing means which interacts with a counter-bearing ( 7 ), and in that the counter-bearing is rotated and lowered after molding in.  
     
     
         12 . A packaging machine having embossing means ( 5 ,  6 ) with which at least one connection element ( 4 ′,  4 ″) can be molded into a packaging.  
     
     
         13 . The packaging machine according to  claim 10 , characterized in that the embossing means ( 5 ,  6 ) are mounted so as to be displaceable crosswise to the direction of transport of the film web.  
     
     
         14 . The packaging machine according to  claim 1 , characterized in that the embossing means ( 5 ,  6 ) cooperate with counter-bearings ( 7 ).  
     
     
         15 . The packaging machine according to  claim 1 , characterized in that it has a sealing station and that the embossing means ( 5 ,  6 ) are downstream of the sealing station.  
     
     
         16 . The packaging machine according to  claim 13 , characterized in that the counter-bearings ( 7 ) are arranged so that they are vertically displaceable.  
     
     
         17 . The packaging machine according to  claim 13 , characterized in that the counter-bearings ( 7 ) are rotatably mounted.  
     
     
         18 . The packaging machine according to  claim 1 , characterized in that it has a sealing station and in that the embossing means ( 5 ,  6 ) are arranged after the sealing station.
