Definitions

  • the invention relates to a method for producing a closure plate according to the preamble of claim 1 (known from EP-A-0798108).
  • Packaging such as B. yogurt cups with closure elements printed on one side, so-called closure boards from z.
  • closure boards As aluminum, which are provided with a heat seal lacquer on the later inside for closing the yogurt cup.
  • a heat seal lacquer layer is applied continuously to one surface side of the aluminum foil in roll form, and then the opposite surface side is printed with pre-varnish and then with a desired motif.
  • the aluminum foil thus produced is then embossed and the shape of the sealing plate is punched out.
  • individual stacks are formed, of which individual blanks, for example, for welding filled cups by means of the heat sealing lacquer.
  • the optical effect of the printed image is adversely affected by the embossing of the closure plates.
  • material stress that can affect product safety. It also increases the thickness of the individual blanks due to the raised surface structure of the embossing, which means that a stack with a given number of blanks requires more packaging space than a non-embossed foil material.
  • a cover element for packaging is proposed in European patent application EP-A-0 79 81 08, which essentially consists of an embossed and an unembossed film, the embossed film facing the packaged goods and on the packaging goods side is provided with a heat seal coating and the non-embossed film is connected to the embossed film via an adhesive layer.
  • EP-A-0 79 81 08 which essentially consists of an embossed and an unembossed film
  • the embossed film facing the packaged goods and on the packaging goods side is provided with a heat seal coating and the non-embossed film is connected to the embossed film via an adhesive layer.
  • a print motif can be applied to the unembossed film on the side facing away from the packaged goods without impairing the optical quality.
  • the production of such a cover element is complex and therefore expensive.
  • closure boards made from a single smooth, unembossed aluminum foil have recently become known. So that these blanks can still be easily separated, spacers made of likewise heat-sealing lacquer are applied to the heat-sealing lacquer side facing the packaged goods in a gravure printing process.
  • this has the disadvantage that two printing processes are required to manufacture the boards. Because the spacers made of heat-sealing lacquer can only be applied using a gravure printing process, whereas print motifs on the opposite side are preferably used using a high-pressure printing process, e.g. B. with the flexographic printing process.
  • closure boards are already known from EP-A-0 798 108, in which elevations for separating them are applied to at least one surface side of the closure board.
  • the invention has for its object to provide a method that is efficient and inexpensive and with the closure boards can be produced that meet the highest requirements in terms of appearance and can still be easily separated.
  • the invention relates to a method for producing a closure plate for closing containers, in which a film material, for. B. aluminum foil, plastic film or the like., Is used.
  • the main idea of the invention lies in the fact that elevations for separating the closure plates from a UV-light-curing material are applied to at least one surface side of the closure plate.
  • UV light-curing material has the advantage that no evaporation of solvent takes place, so that the thickness of the layer application essentially corresponds to the later layer thickness in the dry state.
  • a desired height of elevations or spacers can be achieved with one layer application, without an economically unreasonable or multiple layer thickness application being necessary (as with conventional inks).
  • the surveys are carried out in the high-pressure method, for. B. Flexo printing process printed. That way produce the print motif and the elevations or spacers using a printing process, namely the flexographic printing process. This is possible because with UV-curing materials even in the flexo printing process by one Layer order the elevations or spacers can be generated with a sufficient height.
  • a surface side of the sealing plate is provided with a heat-sealing lacquer before the elevations are applied, the opposite surface side is subsequently printed with a desired motif and finally the elevations are applied to the motif-printed surface end side ,
  • the elevations are applied to the film material in a constant grid dimension. It is advantageous if the elevations are designed as circular islands.
  • the sealing plate 1 shows a cross section of a closure plate produced by the method according to the invention.
  • the sealing plate 1 consists of an aluminum foil 2, which is provided on one surface side with a heat-sealing lacquer layer 3 and on the opposite side has different color layers 4 for producing a desired print motif.
  • the UV-curing colors white, yellow, red, blue and dark blue are preferably superimposed. Of course, any other color combination is possible.
  • spacers likewise made of a UV-light-curing material, are applied to these UV-light-hardened color layers 4. With a single printing step, the height of the spacers of approx. 3-6 ⁇ m is easily possible through the use of the UV light-curing material. If conventional inks are used, at least twice the layer thickness would have to be applied during printing in order to reach this spacer height h after the solvent has evaporated.
  • Fig. 2 the closure board is gem.
  • Fig. 1 shown in plan view. A locking plate with this outer shape is used to close a yogurt cup. To open a closed yogurt cup, this has a pull tab 6 for this purpose.
  • the spacers 5, which are applied in a grid shape on the printed motif, are only shown in sections for clarification.
  • the spacers 5 ensure that a secure separation takes place when tapping closure boards from a punch stack.
