  • the circuit board has on one side a printed image with at least one area which has a lightness or color contrast with the surroundings.
  • the invention further relates to a method for producing such a board.
  • Such boards are used, for example, to close yogurt cups.
  • the side with the printed image is directed outwards, that is, facing away from the packaged goods.
  • the print image can be used for product equipment or labeling of the goods and can contain information about the type and quantity of the packaged goods and the manufacturer.
  • a heat-sealing lacquer is usually applied to the side facing the packaged goods, as a result of which a sealed but peelable connection between the edge of the container and the circuit board can be produced by means of suitable sealing devices.
  • the circuit board usually consists of an aluminum foil or aluminum composite foil with a thickness of 30 to 50 ⁇ m.
  • the circuit board can also consist of paper, plastic or composite foils.
  • Aluminum foils for the manufacture of cup boards are usually already provided on one side with a heat seal coating by the foil manufacturer and on the other side with a primer or pre-varnish. After printing the printed image and a protective varnish, the boards are punched out of the aluminum foil. The boards are stacked in bundles of 1000 pieces, for example. The boards are then removed from the stack one after the other, placed on the containers already filled with the packaged goods and sealed with the container edge.

  • DE-A-41 16 808 discloses a cup-like packaging with a plastic cover film, the cover film having a surface structure. Where the lidding film is not made of metal, it should still be able to be processed in the form of prefabricated boards on high-speed automatic packaging machines. Tearing should be largely prevented when removing the cover film from the packaging.
  • a cover for a food packaging is known from DE-U-298 19 066, the cover being formed from an aluminum foil and the top of the foil being laminated with a cover foil made of aluminum or plastic, and the edge region being free of laminating adhesive to form a grip region. This is intended to ensure that information can be attached to the cover which can be used, read and stored as such even after the cover has been removed.
  • a cover is known in particular for containers of food products, which are made of a plastic or metal foil or a laminate with a
  • the print is arranged between two layers, one of the layers being a low-temperature heat seal lacquer layer. This should make it possible to design small series and samples of such covers so that on the one hand they largely correspond to the later original and on the other hand they can be produced economically.
  • a portion pack for example for coffee cream, is known, on the cover of which a label is glued.
  • the label can be made from a material that is economical even in small quantities can be printed.
  • the label is also intended to enable the portion pack to be reclosed once it has been opened.
  • a peelable label is known, which is attached to the surface of a package.
  • the low adhesive force when the label is sealed onto the packaging can be achieved by alternating raised areas on the sealing surfaces with non-raised areas.
  • the invention has for its object to provide a circuit board for closing a container, which has no embossing, has a smooth surface facing the packaged goods and can still be easily unstacked.
  • this object is achieved in that the circuit board is provided with an additional lacquer layer within the at least one region of the printed image, which has a lightness or color contrast with respect to the surroundings.
  • the invention further relates to the method for producing such a circuit board, a printed image being printed on a carrier material and an additional lacquer layer being applied before or after it, the contour of which corresponds to color or brightness areas of the printed image.
  • the additional lacquer layer Due to this additional lacquer layer, which is only applied to a partial area of the outer side of the board facing away from the packaged goods, the board has no smooth surface on this side.
  • the additional layer of lacquer applied creates a step with a height of a few ⁇ m at the edge of the lacquer layer. As a result, the boards can no longer lie against one another over the full area within a stack and can easily be unstacked individually.
  • the additionally applied lacquer layer preferably has a thickness of 10 to 40 ⁇ m, preferably approximately 20 ⁇ m.
  • the additional coating layer is within a loading kingdom is present, relative to the surroundings has a brightness or color contrast, it is not perceived by the consumer, so 'that the appearance and the aesthetic quality of the printed image will not be affected by the additional resist layer ,
  • the additional lacquer layer It is applied depending on the et or partially depending on the printed image. The step at the edge of the additional print layer therefore coincides with a coloring or brightness contour of the printed image and is therefore not perceived when the board or the container closed with the board is viewed normally.
  • the additional lacquer layer preferably covers only about 10 to 15% of the board and is preferably divided into several areas which are distributed equilibrium to the center of the board. For example, Inscriptions lying opposite each other in the edge areas of the board and a small area in the middle are overprinted with the additional lacquer layer, so that two boards lying on top of each other only touch in the middle and on diametrically opposite edge areas.
  • An outer edge area is expediently kept free and not provided with the additional lacquer layer, since the steps otherwise present at the edge of the additional lacquer layer could cause difficulties when heat-sealing the circuit board onto the edge of the container.
  • the outer edge area for example 2 mm wide, can also be embossed. As a result, the punched edge is defused and possible cuts are prevented.
  • the additional lacquer layer can be a conventional clear lacquer coating. Additives can be added to set a desired layer thickness.
  • the circuit board can consist of an aluminum foil or aluminum composite foil or also of paper, plastic or composite foils.
  • the circuit board according to the invention can be produced in such a way that the printed image is printed on the carrier material, for example an aluminum foil already provided with the printing pre-varnish or primer, in a flexographic, gravure or screen printing process.
  • the additional layer of lacquer can then be applied in the form of a clear lacquer coating.
  • An overprint varnish can then be applied.
  • the additional lacquer layer the contour of which corresponds to certain color or brightness areas of the printed image, can be applied both after the printed circuit board has been printed with the printed image and before it. It is preferably applied after the application of the printed image and before the application of the top coat. The order is expediently also carried out in the flexographic, gravure or screen printing process.
  • the additional lacquer layer is preferably a UV flexo lacquer, the solids content of non-volatile substances of which is approximately 100%.
  • the content of volatile organic substances (V.O.C.) and / or ammonia is preferably less than 0.02%.
  • the indication that the solids content of non-volatile substances is approx. 100% means that the varnish is free of solvents, water and mineral oil. The varnish loses no weight during the curing process using UV light.
  • a sealable coating is applied in a known manner to the underside, which faces the packaged goods. With aluminum foils, this coating is usually used in applied in a separate process and they are already supplied in this print-ready equipment.
  • the coating is preferably completely smooth and has a uniform thickness, which is particularly advantageous for the heat sealing of the circuit board onto the lip of the container. This sealing can also take place by means of filming or sealing edge coating.
  • the circuit board according to the invention preferably has no embossing, since this would impair the optical quality of the printed image.
  • the finished boards are stacked and pressed together to form a compact bundle.
  • the printed circuit boards lie on top of one another with respect to the printed image, i.e. the printed circuit boards are all aligned.
  • the areas of the stacked boards in which the additional lacquer layers are present are therefore also one above the other in register.
  • the additional layer of lacquer on a circuit board can therefore not be pressed or pressed into the circuit board below or above it.
  • a particular advantage of the circuit board according to the invention is therefore that it can be bundled into compact stacks without the surface of the individual circuit boards, which is uneven as a result of the additional layers of lacquer, being pushed through or embossed in other circuit boards.
  • Fig. 1 is a board in plan view
  • FIG. 2 shows the circuit board from FIG. 1 in section according to FIGS. 2-2.
  • the circuit board shown in the drawing has an aluminum foil 10 with a thickness of approximately 30 ⁇ m as the carrier material.
  • An image of a strawberry is used as the motif 12 as an example.
  • Texts 14, 15, which refer to the manufacturing company or references to the composition, are also located on opposite edge regions of the packaged goods can act.
  • the circuit board is circular and has a pull tab 16 on one side, by means of which it can be pulled off the container to open it.
  • the layered structure of the circuit board is shown in FIG. 2, the upper side of the aluminum foil 10 being a pre-varnish
