Description
Die Erfindung betrifft einen Gegenstand mit einem zur Erhöhung der Fälschungssicherheit einen optischen Effekt erzeugenden Oberflächenbereich.The invention relates to an article with a surface area which generates an optical effect in order to increase the security against forgery.
Die Fälschungssicherheit von Verpackungen ist vor allem für die Pharmaindustrie von grosser Bedeutung. Grundsätzlich besteht jedoch auch in anderen Bereichen der Wunsch nach fälschungssicheren Verpackungen oder Produkten, insbesondere in der Konsumgüterindustrie, beispielsweise bei der Verpackung von Lebensmitteln, kosmetischen Artikeln, Kleidern, Software- und Musik CD's oder Wertpapieren. Der Gegenstand mit dem den optischen Effekt erzeugenden Oberflächenbereich kann eine Verpackung, ein Packstoff, ein Packhilfsmittel oder ein Produkt selbst sein, auf dem ein Oberflächenbereich in Form eines Sicherheitsteils, beispielsweise als Etikette, mit einem optischen Effekt ausgestattet ist.The forgery-proof packaging is of great importance especially for the pharmaceutical industry. In principle, however, there is also a desire in other areas for forgery-proof packaging or products, in particular in the consumer goods industry, for example in the packaging of foods, cosmetic articles, clothing, software and music CDs or securities. The article having the optical effect-generating surface region may be a packaging, a packaging material, a packaging aid or a product itself, on which a surface area in the form of a security part, for example as a label, is provided with an optical effect.
Eine fälschungssichere Verpackung oder ein Packhilfsmittel kann als Originalitätsgarantie dienen, die es dem Kunden ermöglicht zu erkennen, dass das von ihm erworbene Produkt tatsächlich vom gewünschten Produzenten hergestellt und verpackt worden ist. Ein fälschungssicheres Packhilfsmittel kann u.a. auch als Erstöffnungsgarantie eingesetzt werden, beispielsweise in Form einer Etikette, einer Banderole oder eines Siegelstreifens usw., die z.B. über einem Flaschenverschluss oder über dem Verschluss eines Weithalsglases, über der Naht zwischen einem Deckel und einem Behälter oder über dem Aufreissverschluss eines Beutels festgelegt worden sind. Beim Öffnen der entsprechenden Verpackung wird die Etikette, die Banderole oder der Siegelstreifen zerstört und damit angezeigt, dass eine Erstöffnung bereits erfolgt ist. Es ist auch möglich; Gegenstände in eine Umverpackung zu füllen oder einzuhüllen, wobei die Umverpackung charakteristische unverwechselbare und nicht kopierbare Merkmale aufweist, welche zeigen, dass das Verpacken des Inhalts bei einem bestimmten Lieferanten erfolgt ist.A tamper evident packaging or packaging aid may serve as a tamper evidence guarantee that allows the customer to recognize that the product he has purchased has actually been manufactured and packaged by the desired producer. A tamper-resistant packaging aid can also be used, among other things, as a first-opening guarantee, for example in the form of a label, a banderole or a sealing strip, etc., for example over a bottle cap or over the closure of a wide-necked glass, over the seam between a lid and a container or over the zipper of a bag. When opening the appropriate packaging, the label, the banderole or the sealing strip is destroyed, indicating that an initial opening has already taken place. It is also possible; To fill or wrap objects in an outer packaging, with the outer packaging has characteristic distinctive and non-duplicable features which show that the packaging of the contents has been done at a particular supplier.
Bekannte fälschungssichere Verpackungen und Produkte sind auf ihrer Oberfläche mit Hologrammen versehen oder weisen Farbcodierungen oder unsichtbare Merkmale auf. Zur Erzielung einer hohen Fälschungssicherheit haben sich in der Praxis u.a. Hologramme bewährt. Beispiele sind Hologrammetiketten oder Deckelfolien mit integrierten Hologrammen. Die Erzeugung von individualisierten Hologrammen ist jedoch mit einem enormen Aufwand verbunden.Known anti-counterfeiting packaging and products are provided with holograms on their surface or have color codings or invisible features. In order to achieve a high security against counterfeiting u.a. Holograms proven. Examples are hologram labels or lidding films with integrated holograms. The production of individualized holograms is, however, associated with an enormous effort.

Der Erfindung liegt die Aufgabe zugrunde, zumindest ein Teil der Oberfläche von Gegenständen wie Verpackungen, Packstoffe, Packhilfsmittel oder Produkte selbst mit einem im sichtbaren Licht nicht erkennbaren optischen Effekt als Sicherheitsmerkmal gegen Fälschungen auszustatten.The invention is based on the object of equipping at least a part of the surface of objects such as packaging, packaging materials, packaging aids or products themselves with an optical effect not recognizable in the visible light as a security feature against counterfeiting.
Zur erfindungsgemässen Lösung der Aufgabe führt bei einem Gegenstand der eingangs genannten Art, dass der Oberflächenbereich mit dem optischen Effekt ein Bildmuster in der Form eines ersten Rasters mit zusätzlichen Informationen, die erst nach Dekodierung mit einem zweiten Raster sichtbar werden, enthält, wobei die Dimensionen des ersten Rasters und die Dimensionen des zweiten Rasters so aufeinander abgestimmt sind, dass die beiden Raster Moiré-Interferenzen zeigen, wobei der zweite Raster auf einer zum Auflegen auf den Oberflächenbereich mit dem optischen Effekt bestimmten Prüffolie angeordnet ist, und wobei das Bildmuster mit dem die zusätzlichen Informationen enthaltenden ersten Raster und der zweite Raster erst im UV-Licht sichtbare Farbendruckmuster sind.For the inventive solution of the problem results in an article of the type mentioned that the surface area with the optical effect, an image pattern in the form of a first grid with additional information that will be visible only after decoding with a second grid contains, the dimensions of first raster and the dimensions of the second raster are coordinated so that the two rasters show moire interference, wherein the second raster is arranged on a test film intended to be placed on the surface area with the optical effect, and wherein the image pattern with the additional Information containing first grid and the second grid are only visible in UV light color print pattern.
Bevorzugte Rasterelemente sind Linien, Gitter, Polygone, insbesondere 3-, 4- und 6-eckige Polygone sowie runde und ovale Punkte.Preferred raster elements are lines, grids, polygons, in particular 3-, 4- and 6-cornered polygons as well as round and oval points.
Bevorzugt ist der zweite Raster ein gleichförmiges Linienmuster und der erste Raster des ersten Bildmusters ein auf das gleichförmige Linienmuster des Zweiten Rasters abgestimmtes Muster.Preferably, the second raster is a uniform line pattern and the first raster of the first image pattern is a pattern matched to the uniform line pattern of the second raster.
Das erste Bildmuster kann beispielsweise auf die Oberfläche eines folienförmigen Materials aufgedruckt sein.For example, the first image pattern may be printed on the surface of a sheet-like material.
Das folienförmige Material kann z. B. eine opake Folie, insbesondere eine Aluminiumfolie, und die Prüffolie eine transparente Kunststofffolie, oder umgekehrt, sein, oder das folienförmige Material und die Prüffolie sind beides transparente Kunststofffolien.The film-shaped material may, for. Example, an opaque film, in particular an aluminum foil, and the test film is a transparent plastic film, or vice versa, or the film-shaped material and the test film are both transparent plastic films.
Um den erfindungsgemässen Effekt zu erzeugen, sind die von den Moiré-Mustern her bekannten Distanzen zwischen benachbarten Rasterementen einzuhalten. Die Bildmuster können beispielsweise aus einzelnen parallelen Linien bestehen, punktförmig aufgebaut sein oder auch eine Kombination von geraden und gekrümmten Linien oder anderen Rastern enthalten.In order to produce the effect according to the invention, the distances known from the moiré patterns between adjacent raster elements must be observed. The image patterns may, for example, consist of individual parallel lines, be punctiform or contain a combination of straight and curved lines or other grids.
Im einfachsten Fall ist der zweite Raster auf der Prüffolie, auch "Linse" genannt, ein gleichförmiges Linienmuster aus einzelnen parallelen Linien mit gleicher Distanz zwischen benachbarten Linien, und der erste Raster des auf der Oberfläche des Gegenstandes aufgebrachten Bildmusters ist ein auf den zweiten Raster abgestimmtes, durch Kodierung zusätzliche Informationen in den Linien enthaltendes Muster. Die Kodierung entsteht dadurch, dass an Stellen, die bei der Detektion sich im Kontrast abheben sollen, eine Verschiebung der Bildelemente vorgenommen wird. Es können damit z. B. Markennamen und dgl. Zeichen Markennamen und dgl. Zeichen, die erst nach Auflegen der Prüffolie im UV-Licht sichtbar werden, in den Packstoff eingebaut werden.In the simplest case, the second raster on the test film, also called "lens", is a uniform line pattern of individual parallel lines with equal spacing between adjacent lines, and the first raster of the image pattern applied to the surface of the article is matched to the second raster , by patterning additional information contained in the lines pattern. The coding arises from the fact that a shift of the picture elements is carried out at points which are supposed to stand out in contrast during the detection. It can thus z. As brand names and the like. Sign brand names and the like. Signs that are visible only after placing the test film in UV light, are installed in the packaging material.
Der Betrag der Verschiebung der Bildelemente kann dabei optional so gesteuert werden, dass damit Kontrastzwischenwerte erzielt werden, also z. B. auch ein Tonstufen-Bild erzeugt werden kann.The amount of displacement of the picture elements can be optionally controlled so that contrast intermediate values are achieved, ie, for. B. also a sound stage image can be generated.
Werden Linien als Rasterelemente verwendet, kann der Moiré-Effekt auch mit lentikularen Linsen erzielt werden. In diesem Fall findet nicht eine Interferenz statt, sondern es werden durch die lentikulare Linse Teile des ersten Bildmusters ausgeblendet, so dass entweder nur die unveränderten oder aber die veränderten Bereiche gesehen werden. Der Effekt ist aber an sich der gleiche. Der Rillenabstand der lentikularen Linsen muss dabei auf die Linienfrequenz des ersten Bildmusters abgestimmt sein.If lines are used as raster elements, the moiré effect can also be achieved with lenticular lenses. In this case, there is no interference, but the lenticular lens makes parts of the first image pattern hidden, so that either only the unchanged or the changed areas are seen. The effect is the same in itself. The groove spacing of the lenticular lenses must be matched to the line frequency of the first image pattern.
Selbstverständlich können die Raster auch eine Kombination von geraden und gekrümmten Linien oder anderen Bildelementen enthalten.Of course, the screens may also contain a combination of straight and curved lines or other picture elements.
Ein bevorzugtes Anwendungsgebiet des erfindungsgemässen Gegenstandes sind Verpackungsmaterialien, wie z. B. Deckfolien von Blisterpackungen, aber auch Faltschachteln, Glasflaschen und Beutel für Medikamente.A preferred field of application of the inventive article are packaging materials, such. As cover sheets of blister packs, but also cartons, glass bottles and bags for medicines.
