  • Packing container with an originality marking and method for the production thereof

    Abstract: A packaging tube provided with an originality marking and a method for the production thereof. Normally the price of tubes increases according to the type of marking. This is avoided by virtue of the fact that weld joints, e.g. between the head and the tube are made visible and the joining materials are colored differently than the part of the tube that they connect.
