Definitions
- the invention relates to a method for producing a container, such as a can or tube, for receiving a filling material, the interior of which is primed after the container has been produced.
- JP-A 58 101 049 deals with the basic coating of metal goods. It is mentioned there that a polyolefin-coated metal product is produced by providing a metal surface with a primer and coating it with polyolefin after the primer has been stoved. After baking and drying, the primer has a thickness of 10 to 100 ⁇ m. This method is not readily applicable to containers.
- cans have been produced by pressing, deep-drawing or the like. This is followed by trimming and washing, followed by drying. An internal protective lacquer is then usually sprayed on, in a thickness of approximately 6-8 ⁇ m, which in turn is dried.
- An internal protective lacquer is then usually sprayed on, in a thickness of approximately 6-8 ⁇ m, which in turn is dried.
- the disadvantage is that such cans or tubes are not resistant to aggressive contents.
- the inventor set himself the goal of using a method of the above. To develop a way in which a container is created which has this resistance to aggressive filling goods and in which, if necessary, existing seams are sealed.
- a coating of polyolefin or a mixture of polyolefins, polyethylene or other plastics is applied to the primer in a layer thickness of 30 to 70 ⁇ m and the container is then exposed to a heat of preferably 160 to 190 ° C. in a drying oven, and is then actively cooled to preferably 40 to 50 ° C.
- This relatively strong coating is particularly suitable for containers for holding aggressive filling goods. These containers can be tubes or aluminum cans. Furthermore, the coating is also suitable for tin cans, since it is usually sealed by the coating in the case of tin cans. However, the coating is also suitable for plastic cans.
- the primer generally has a layer thickness of 20 to 30 ⁇ m, so that the layer thickness of the primer and coating is approximately 50-100 ⁇ m.
- the coating for example, polyolefins or similar substances as well as mixtures of polyolefins and their substances are suitable. This has the major advantage that polyolefins burn when the container is recycled without polluting the environment.
- the coating can also consist of a polyethylene or other plastics. There should be no limit to the inventive idea here.
- the container is then placed in a drying oven and exposed to a heat of 160-190 ° C. Thereafter, the container is preferably cooled to 40-50 ° C.
- the outside of the container is treated by applying a special one-component base coat that can be applied at low temperatures when drying to avoid damaging the inside coating. Then a top coat is applied.
- Such a coating according to the invention is also suitable for a valve cover that is to be placed on a can later. It is mainly used for aerosol cans.
