Container with container side walls made of metal, container bottom portion made of metal and container lid made of metal

Abstract

A container with container side walls made of metal, a container bottom portion made of metal and a container lid made of metal, characterized in that the container side walls are joined with each other and/or with the container bottom portion and/or with the container lid, at least in certain areas, by means of a cold pressing technique. The container side walls and/or the container bottom portion and/or the container lid are, at least in certain areas, provided on outsides with a zinc coating and on this zinc coating a polymer coating is applied.

1 . A container comprising container side walls ( 3 , 4 ) made of metal, a container bottom portion ( 5 ) made of metal and a container lid ( 6 ) made of metal, characterized in that the container side walls ( 3 , 4 ) are joined with each other and/or with the container bottom portion ( 5 ) and/or with the container lid ( 6 ), at least in certain areas, by means of a cold pressing technique, the container side walls ( 3 ,  4 ), at least in certain areas on their outside, being provided with a zinc coating ( 8 ) and on this zinc coating ( 8 ) a polymer coating ( 10 ) being applied.  
   
   
       2 . A container according to  claim 1 , wherein the container bottom portion ( 5 ) on the outside, at least in certain areas, comprises a zinc coating ( 8 ), on which a polymer coating ( 10 ) is applied.  
   
   
       3 . A container according to any one of the claims  1  or  2 , wherein the container lid ( 6 ) on the outside, at least in certain areas, comprises a zinc coating ( 8 ), on which a polymer coating ( 10 ) is applied, the container lid ( 6 ) being joined to the container side walls ( 3 ,  4 ) by means of a cold pressing technique.  
   
   
       4 . A container according to any one of the claims  1 ,  2  or  3 , wherein a U-shaped casing element ( 7 ) forming the container bottom portion ( 5 ) and two container side walls ( 3 ) is joined with two additional container side walls ( 4 ).  
   
   
       5 . A container according to any one of the  claims 1  to  4 , wherein the container is configured as a double-walled container, the container side walls ( 3 ,  4 ) and the container bottom portion ( 5 ) as well as the container lid ( 6 ) forming an external container ( 1 ) and in this external container ( 1 ) an inner container ( 2 ), which is preferably made of plastic, being accommodated.  
   
   
       6 . A container according to any one of the  claims 1  to  5 , wherein the connection established by means of a cold pressing technique is a flanged connection, a riveted joint or a folded seam connection.  
   
   
       7 . A container according to any one of the  claims 1  to  6 , wherein the thickness of the zinc coating ( 8 ) on the outside of the container side walls ( 3 ,  4 ) and/or on the outside of the container bottom portion ( 5 ) and/or on the outside of the container lid ( 6 ) is 5 to 40 μm, preferably 8 to 35 μm and preferred 10 to 30 μm.  
   
   
       8 . A container according to any one of the  claims 1  to  7 , wherein the thickness of the polymer coating ( 10 ) on the zinc coating ( 8 ) of the outside of the container side walls ( 3 , 4 ) and/or on the zinc coating ( 8 ) of the outside of the container bottom portion ( 5 ) and/or on the zinc coating ( 8 ) of the outside of the container lid ( 6 ) is 0.2 to 6 μm, preferably 0.3 to 5 μm, preferred 0.4 to 4.5 μm and very preferred 0.4 to 4 μm.  
   
   
       9 . A container according to any one of the  claims 1  to  8 , wherein the polymer coating ( 10 ) is transparent.  
   
   
       10 . A method for producing a container comprising container side walls ( 3 ,  4 ) made of metal, a container bottom portion ( 5 ) made of metal and a container lid ( 6 ) made of metal, characterized in that to the outside of the container side walls ( 3 , 4 ) and/or to the outside of the container bottom portion ( 5 ) and/or to the outside of the container lid ( 6 ) a zinc coating ( 8 ) is applied, on which zinc coating ( 8 ) a polymer coating ( 10 ) is applied, the container side walls ( 3 , 4 ) being joined with each and/or with the container bottom portion ( 5 ) and/or with the container lid ( 6 ), at least in certain areas, by means of a cold pressing method.
