Definitions

  • the invention relates to a product securing element for the protection of a plurality of similar products and a method for securing a variety of similar products.
  • High-quality products and their packaging are often provided with product protection elements as security, which serve as a proof of authenticity and should prevent unauthorized reproductions.
  • luminescent substances for authenticity assurance.
  • the presence of the luminescent substances can be easily checked, for example, with the aid of a UV lamp.
  • fluorescent mottling fibers may be incorporated from short fiber cores provided with a fluorescent coating.
  • the mica fibers are invisible, but under UV illumination, they appear clearly despite their small size due to their bright colored fluorescence.
  • the printing of true color luminescence images is also known. This special colors are printed on, which are not visible under normal lighting and after excitation by UV light, a comparable color impression as a classic image, such as a portrait of the passport owner show.
  • the object of the invention is to specify a product securing element which connects the cost-effective production, which is indispensable in the product securing area, with high counterfeit protection.
  • the invention provides a product securing element for securing one of a plurality of similar products, which is a serial number plate, that is identical for all similar products to be protected and includes an individualization mark, which is unique for each product to be protected.
  • the serial code comprises a luminescence region which can be excited by UV radiation
  • the individualization code comprises a modification region which is invisible in the visible spectral region and locally modifies its luminescence in cooperation with the luminescence region upon UV excitation of the luminescence region and thereby visually and / or mechanically detects the individualization identifier ,
  • the identical for all similar products serial number plate can be produced with a fast and cost-effective method, for example in offset printing and provides a basic insurance for all products provided with it.
  • the unique individualization indicator for each product to be protected additionally enables a clear individualization of the respective product.
  • the two markings are closely interwoven, since the modification region locally modifies the luminescence of the luminescence region and thus produces a strong interaction. In some designs, the information contained in the modification region is not readable without the luminescence region.
  • the interaction of the two markings offers several significant advantages: Thus, the counterfeiting security of the product securing element is increased by the interaction, since a correct interaction of the two elements is required for a successful authenticity check.
  • the production of the serial number plate can be easily separated from the production of the individualization code, since the securing effect is achieved only by the combination of the two elements. So can the two elements are manufactured by different manufacturers in different production plants using different methods. For example, a product packaging can be provided with the series designation by a packaging manufacturer, while the individualization designation in the form of an adhesive label is provided separately by a security provider. Even though this only provides the individualization marks, it nevertheless retains complete control over the number and use of the product protection elements produced.
  • the luminescence region can already be visible without aids and be combined, for example, with conventional printing inks. In an advantageous embodiment, however, it is provided that the luminescence region is invisible in the visible spectral range without UV excitation.

  • the luminescence region may, for example, contain a true color image from the luminescent primary colors red, green and blue or else show any other multicolored image.
  • the modification region is arranged above the luminescence region, in particular printed on the luminescence region.
  • Modification region and luminescence region are in an advantageous design in a fixed spatial relationship to each other. In other equally useful designs, the two areas are on different parts of a product and / or its packaging.
  • the modification region contains a UV absorber and reduces the luminescence of the luminescence region in at least one UV excitation wavelength range (UV-A, UV-B and / or UV-C).
  • the modification region contains a luminescent substance and modifies the luminescence of the luminescence region by additive color mixing.
  • the luminescent substance of the modification region advantageously differs in its luminescence color from the luminescence colors of the luminescence region.
  • the luminescence region can also be arranged with a first subregion above and with a second subregion below the modification region.
  • visually high-quality designs can be generated in a simple manner.
  • the parts of the modification region with or without a luminescence region arranged above them can appear perfectly matched with different colors on UV excitation without requiring a registration of the luminescence region and the modification region with respect to one another.
  • the modification area advantageously comprises an alphanumeric digit sequence or a 1- or 2-dimensional code, such as a bar code, a bar code, or a QR code.
  • a 1- or 2-dimensional code such as a bar code, a bar code, or a QR code.
  • the information of the individualization indicator can already be detected purely visually, in other designs, such as a QR code, the license plate is indeed visually visible in UV light, but required for decrypting the information contained one machine detection.
  • the luminescence region and the modification region can both be in the form of a print layer on the product to be protected.
  • the modification region can also be present on an adhesive strip, in particular a slotted adhesive strip.
  • the adhesive strip is adhered to the product to be protected, preferably in the region of a closure opening, where it forms the product securing element together with the luminescence region. If the adhesive strip is removed or the product packaging is opened, the integrity of the product securing element is destroyed. The luminescence region and the modification region can then not be easily returned to their original, product-securing positions.
  • a slit adhesive strip is irrevocably destroyed when the package is opened or when it is removed from the package and therefore can not be reused.
  • the product securing element is advantageously a brand protection label, preferably with a peel-off indicator, or represents a seal or tamper-evident closure, in particular for bottles or cartons.
  • the peel-off indicator may also be, for example, that when removing the product securing element from a package or opening the package a part of the luminescence region and / or the modification region remains on the packaging, while another part remains on the product protection element itself.
  • the product securing element can also be a thermoformed plastic film, in particular a blister pack or a molded part of a branded article. Furthermore, it can also be a shrink film.
  • the modification region is produced in an adhesive strip only after the adhesive strip has been applied to the packaging to be secured.
  • the packaged tablets or capsules are usually packaged in a blister pack protected from contamination and at the same time a visually recognizable precise removal is simplified.
  • a blister pack usually consists of a transparent top layer, which takes up the shape of the tablets or capsules and an aluminum pad with a blister varnish, which may still contain information about the product on the back.
  • the transparent blister top can be provided, for example by means of inkjet, with a modification region or a luminescence region in the form of a first fluorescence, and a transparent window in the cardboard packaging can be provided with a second information that forms the associated luminescence region or modification region.
  • the two areas created in the blister and the package then form a product securing element of the type described above and complement each other under UV illumination to a predetermined, affirming the authenticity of the products appearance. This makes it possible, in particular, to check the product or the originality of the product without opening the packaging.
  • the tax stamp for a cigarette packet then carries a modification region or a luminescence region in the form of a first fluorescence and the transparent outer packaging carries the second information that forms the associated luminescence region or modification region.
  • the product to be protected for example, be a license plate number.

  • the inventive solution would be suitable if with the creation of the license plate a first fluorescent badge is applied, which carries a first piece of information. With the payment of the vehicle tax, the vehicle owner receives a second label, which is then applied to the first label.
  • the labels are designed so that they can not be removed non-destructively.
  • the test is carried out by the police using a conventional UV hand lamp.
