Definitions

  • the present invention relates to a tamper-proof packaging material with a Security feature, with the security feature one on the packaging material arranged coded image arrangement, which by overlaying Releases an image or sequence of images with an associated decoder element.
  • Counterfeit-proof packaging contain a guarantee of originality, which it to the customer or a specific Circle of people makes it possible to recognize that the product in Produced by the desired producer or a trusted third party company and has been packed.
  • Counterfeit-protected items such as products (for example, documents, securities, Consumer goods, spare parts, etc.) or their associated packaging usually so-called security features, which affect the surface of the object are applied.
  • Preferred security elements are characterized a human eye variable appearance, which by means of specific measures is achieved.
  • security elements known which by changing the viewing angle different Let perceive picture elements and in this way the impression of a cause moving picture.
  • So are well-known forgery-proof packaging and products bsp. provided with holograms on their surface, their image motifs change its appearance when the viewing angle is changed. The production However, holograms are associated with a lot of effort.
  • security elements which have an applied on the packaging, coded, i. encoded, image include, in which by overlay with a so-called decoder element, i. Decryption element an image encoded in it comes to light.
  • the decoder element contains, for example, a number of optical lenses, which are the underlying ones Pixels of the apparent random pattern to the human eye so divert that the picture elements of the apparent random pattern as meaningful Assemble picture.
  • the apparent random pattern is on the optics matched the lens elements used.
  • the production of such coded Images for decryption with a decoder element containing optical lenses requires complex data processing programs. Furthermore, the production is the necessary for decryption lenticular lenses, which as a rule must be cast and have a high accuracy of fit, technically very expensive.
  • decoder elements has the advantage that these delivered separately from the packaging to the end user or a control body can be. They are therefore a kind of key.
  • conventional security elements which contain such decoder elements, and which generate moving pictures when they are decrypted, the disadvantage that these are relatively complex and expensive to produce, as already mentioned.
  • the invention is therefore based on the object, a packaging material to propose a cost-effective security feature in its manufacture, wherein the security feature is at least part of the surface of the packaging material covering, coded image arrangement and a decoder element for decrypting the coded image arrangement by generating a optical effect includes.

  • the width of the lines or bars of the grid is a multiple of the width of the intermediate window area. So can bsp. the width of the lines or bars is 2 to 20 times, in particular 3- to 10-fold, the width of the intervening window area include. The greater the resolution of the image sequence, i. the denser the frames nested, the bigger this factor is.
  • the maximum width extension of the strip-shaped picture elements preferably corresponds the width of the window areas.
  • the maximum width extension of the However, picture elements can also be larger than the width of the window areas.
  • the coded picture arrangement and the decoder element can thus be superimposed on one another Be agreed that the said optical effect by turning or lateral relative movement the decoder element with respect to the image arrangement occurs.
  • the optical effect by one opposite the image arrangement rectilinear, lateral relative movement of the decoder element achieved.
  • the effect of a moving image is especially at a uniform Moving the decoder element over the image arrangement achieved.
  • the coded image arrangement is preferably such that it is uniform forms ornamental structure.
