Description

Die Erfindung betrifft Sicherheitsmerkmale, vorzugsweise Aufreißbänder bzw. -fäden, zur Identifikation der Originalität von Produkten durch den Hersteller oder befugte Kontrollorgane.The invention relates to security features, preferably tear strips or threads, to identify the originality of products by the manufacturer or authorized Controlling bodies.

Durch Produktpiraterie und unautorisierte Produktion von diversen Markenprodukten beispielsweise in der Arzneimittel-, Textil- und Kosmetikindustrie sowie in der Ersatzteilbranche erwachsen den Originalproduzenten enorme materielle Schäden und Image-Verluste. Bei der Produktpiraterie und unautorisierten Produktion von hochpreisigen Konsumgütern, welche nicht der Qualität des Originals entsprechen, ist sowohl dem Hersteller als auch einem Großteil der Verbraucher daran gelegen, die Waren auf Echtheit prüfen zu können. Hierzu werden diese üblicherweise mit sichtbaren Sicherheitsmerkmalen versehen. Als Sicherheitsmerkmale werden beispielsweise Hologramme auf die Produkte aufgebracht. Eine weitere Möglichkeit besteht darin, die Verpackungen der Produkte mit Sicherheitsmerkmalen zu versehen. Beispielsweise werden zum Öffnen der Verpackungen um das Verpackungsmaterial herum Fäden, Bänder oder Schnüre eingelegt. Als Sicherheitsmerkmal sind diese sogenannten Aufreißmittel meist andersfarbig gestaltet, mit einer fühlbaren Materialstärke ausgestattet und teilweise mit einer scharfen, spürbaren Kante versehen. Ein Ende dieser Aufreißfäden ist meist als eine frei heraushängende, für den Benutzer bequem greifbare Lasche ausgebildet. Auch die Gestaltung dieser Lasche - beispielsweise deren Form, Länge oder Breite - wird als Originalitätsnachweis verwendet.Through product piracy and unauthorized production of various branded products For example, in the pharmaceutical, textile and cosmetics industries and in the Spare parts industry causes the original producers enormous material damage and image losses. In product piracy and unauthorized production of high-priced consumer goods, which do not correspond to the quality of the original, is the manufacturer as well It is also important for a large proportion of consumers to be able to check the authenticity of the goods. For this they are usually provided with visible security features. When Security features, for example, holograms are applied to the products. A Another possibility is to package the products with security features to provide. For example, to open the packaging to the packaging material threads, ribbons or strings are inserted around. As a security feature are these so-called Tear-up usually designed differently colored, equipped with a tactile material thickness and partly provided with a sharp, noticeable edge. An end to these tears is usually designed as a free-hanging, convenient for the user tab. The design of this flap - for example, the shape, length or width - is used as proof of originality.

Obwohl bei nicht hochwertigen Produkten meist auf diesen Aufwand verzichtet wird und oftmals der Aufreißfaden aus demselben Material wie die Verpackung besteht, ist immer häufiger zu beobachten, dass die bisher angewandten Merkmale zur Kennzeichnung der Originalität nicht ausreichen, um das Original wirksam zu schützen. Aufgrund der fortschreitenden Entwicklung der auch für den Fälscher zugänglichen Techniken sind die Originalitäts- und Sicherheitsmerkmale jedoch leicht nachzuahmen und herzustellen. Die Forderung nach Erhöhung der technologischen Hürde für Fälscher wird immer größer. Although for non-high-quality products usually waived this effort and often the tearing thread is made of the same material as the package is to observe more and more often that the characteristics used so far for labeling of originality are insufficient to effectively protect the original. Due to the progressive Development of the technologies that are also accessible to the counterfeiter are the originality and security features, however, easy to imitate and manufacture. The requirement After increasing the technological hurdle for counterfeiters is getting bigger.

In vielen Wirtschaftsbranchen erleiden die Hersteller erhebliche Verluste durch sogenannte "graue Ware". Dabei haben die Verbraucher meist hinsichtlich der "grauen Ware" kein besonderes Interesse an einer Echtheitsprüfung. Die Ware entspricht dem Original und ist in der Regel zu einem wesentlich tieferen Preis erhältlich. Hier liegt das Hauptinteresse an einer Echtheitsprüfung bei dem Hersteller. Es werden hier verdeckte und humanvisuell nicht erkennbare Sicherheitsmerkmale bevorzugt eingesetzt. Die Verbraucher werden durch Designänderungen nicht verunsichert. Die Unkenntnis der Art und Lage der Sicherheitsmerkmale soll verhindern, dass sich der Fälscher bei der Herstellung z. B. der Verpackung für "graue Ware" auf die Prüftechnik und Prüfgeräte einstellen kann. Ein generelles Problem sowohl bei der Produktpiraterie als auch bei der unautorisierten Produktion stellt die unautorisierte Herstellung von Verpackungen und Umverpackungen oder aber auch der Diebstahl derer, mit denen die Fälschungen oder die graue Ware verpackt werden und damit Originalität vorgetäuscht wird, dar.In many sectors of industry, manufacturers are suffering considerable losses so-called "gray goods". Most consumers have "gray goods" no particular interest in an authenticity check. The goods correspond to the original and is usually available at a much lower price. Here is the main interest an authenticity check with the manufacturer. It does not become covert and human visual recognizable security features preferably used. Consumers are being influenced by design changes not unsettled. Ignorance of the nature and location of the security features should prevent the counterfeiter in the production z. B. the packaging for "gray goods" on the testing technology and test equipment can adjust. A general problem both at the product piracy as well as at the unauthorized production represents the unauthorized Production of packaging and outer packaging or even the theft of those, with which the fakes or the gray goods are packed and thus originality is simulated, dar.

In der EP 0 317 202 wird eine Verpackung mit einem Aufreißband beschrieben, wobei dieses zur Aufnahme magnetisch kodierter Informationen mit einem magnetisierbaren Material beschichtet ist.EP 0 317 202 describes a package with a tear tape, this being for receiving magnetically encoded information with a magnetizable Material is coated.

Die WO 99/43556 A1 beschreibt Aufreißfäden als Sicherheitsmerkmal für Verpackungen mit einem oder mehreren Perforationslöchern, wobei diese beispielsweise Firmenlogos darstellen. Weiterhin werden Aufreißfäden mit einzelnen metallisierten Abschnitten verwendet, wobei sich innerhalb dieser metallisierten Abschnitte demetallisierte Zonen, welche insbesondere Figuren oder Buchstaben darstellen, befinden und/oder die metallisierten Abschnitte Hologramme darstellen. Aber auch die Kombination des optisch wirksamen Sicherheitsmerkmals mit einer elektrisch wirksamen Merkmalsfarbe zur Kodierung von Informationen wird beschrieben.WO 99/43556 A1 describes tearing threads as a security feature for Packaging with one or more perforation holes, which, for example, company logos represent. Furthermore, tear threads with individual metallized sections used, wherein within these metallized sections demetallisierte zones, which represent in particular figures or letters, and / or the metallized Portions represent holograms. But also the combination of the optically effective security feature with an electrically effective feature color for coding information is described.

In der DE 198 08 288 A1 wird vorgeschlagen, einzelne Abschnitte des Aufreißfadens vorzugsweise mit einer Beschichtungsdicke von 70 nm bis 200 nm zu metallisieren und innerhalb dieser metallisierten Abschnitte wiederum Zonen zu demetallisieren, beispielsweise Figuren oder Buchstaben darstellend. Eine Kompatibilität zu den bisher verwendeten Herstellungsmethoden und technologischen Herstellungsgeschwindigkeiten ist nicht gegeben. Durch die Strukturierung mittels Masken oder anderer Abdeckungen wird keine genügend hohe Auflösung erreicht. bzw. sind deren Nutzungsdauer zu gering.DE 198 08 288 A1 proposes individual sections of the tear thread preferably to be metallized with a coating thickness of 70 nm to 200 nm and to demetallate zones within these metallized sections, for example Representing figures or letters. Compatibility with the previously used Manufacturing methods and technological production speeds are not given. By structuring using masks or other covers will not be enough high resolution achieved. or are their useful lives too low.

Bekannt sind außerdem Metallisierungsbeschichtungen hergestellt durch Drucken. Beschichtungen hergestellt mittels metallischer Druckfarben lassen eine höhere Auflösung je nach Druckart, beispielsweise bei Streudrucken zu. Die Bindemittelauswahl ermöglicht die Einstellung der partiellen Flächenwiderstände. Die Brillanz der Oberfläche liegt unter der durch Vakuumbeschichtungsverfahren hergestellten Oberflächen. Für Sicherheitsmerkmale, realisiert durch Metallisierungen mit partiellen Flächenwiderstandsänderungen bei gleichzeitiger höchstmöglicher Brillanz der Oberfläche, stehen keine anwendbaren industriellen Technologien, insbesondere Vakuumtechnologien zur Verfügung, weil die üblichen Verarbeitungs- bzw. Herstellungsgeschwindigkeiten von ≥ 500 m/min nicht erreicht werden.Also known are metallization coatings produced by printing. Coatings produced by means of metallic printing inks allow a higher resolution depending on the type of printing, for example with scattered prints too. The binder selection allows the setting of the partial surface resistances. The brilliance of the surface is below the surfaces produced by vacuum coating processes. For security features, realized by metallization with partial surface resistance changes At the same time the highest possible brilliance of the surface, are no applicable industrial Technologies, especially vacuum technologies, because the usual processing or manufacturing speeds of ≥ 500 m / min can not be achieved.

Alle vorbeschriebenen, verschiedenen Sicherheitsmerkmale, -vorkehrungen und Techniken werden in zunehmendem Maße von Fälschern in großen Maßstäben beherrscht und zumeist schon industriell angewendet, so dass zunehmend auf allen Märkten Fälschungen und "graue Ware" in Größenordnungen angeboten werden.All the above, various security features, precautions and techniques are increasingly dominated by counterfeiters on a large scale and mostly already applied industrially, so that increasingly in all markets fakes and "gray goods" are offered in orders of magnitude.

Aufgabe der Erfindung ist es neben der Überwindung der Nachteile aus dem Stande der Technik, Aufreißbänder bzw. -fäden, zur Identifikation der Originalität von Produkten durch den Hersteller oder befugte Kontrollorgane vorzuschlagen. Aus der wahlweisen nur dem Hersteller bzw. dem befugten Kontrollorgan bekannten Kombination von metallisierten Flächen, Flächenbrillanz, elektrisch leitfähigen Flächen und Flächenwiderstandsänderungen sind für den Fälscher nicht überwindbare technologische Hürden vorzuschlagen.The object of the invention, in addition to overcoming the disadvantages of the Known art, tearing tapes or strings, for identifying the originality of products to be proposed by the manufacturer or authorized regulatory bodies. From the optional only known to the manufacturer or the authorized control body combination of metallized Surfaces, surface brilliance, electrically conductive surfaces and surface resistance changes are to be proposed for the counterfeiter unconquerable technological hurdles.

Die erfindungsgemäßen Sicherheitsmerkmale sind aus mehreren verschiedenen Komponenten, Kodiermitteln und elektrisch leitenden Schichten aufgebaut, wobei diese in unterschiedlicher Anordnung mit einem Trägersubstrat verbunden sind. Schichten an sich bekannter elektrisch leitender Polymere finden Anwendung. Diese Sicherheitsmerkmale stellen gemäß dieser Erfindung Aufreißbänder dar, welche mit einer Verpackung, beispielsweise verpresst, verklebt oder gesiegelt, verbunden sind. Voraussetzung für die Nutzung von elektrisch leitenden Polymerschichten in Kombination mit einer Metallisierungsschicht ist eine deutliche Differenz zwischen den Flächenwiderständen (≈ 100 kΩ / □), insbesondere ist ein sehr hoher elektrischer Flächenwiderstand der Metallisierungsschicht gefordert (≈ 200 kΩ / □). Die marktüblichen und angewendeten Technologien zur Metallisierung erreichen geringe Flächenwiderstände.The security features according to the invention are made of several different ones Components, encoders and electrically conductive layers constructed, these in different arrangement are connected to a carrier substrate. Layers themselves known electrically conductive polymers are used. These security features provide According to this invention tear strips, which with a packaging, for example pressed, glued or sealed, are connected. Prerequisite for the use of electrical conductive polymer layers in combination with a metallization layer is one significant difference between the surface resistances (≈ 100 kΩ / □), in particular is a very high electrical surface resistance of the metallization required (≈ 200 kΩ / □). Achieve the market and applied metallization technologies low surface resistances.

Insbesondere die Beschichtung mittels elektrisch leitendem Polymer, z. B. Polyethylendioxythiophenpolystyrolsulfonat (PEDT/PSS) in Kombination mit einer Metallisierungsschicht ist als technologische Hürde für Fälscher zu nutzen, wobei sich das PEDT/PSS durch einen Flächenwiderstand im Bereich von 15-100 kΩ / □ auszeichnet. Auf PE-Folien wird unter Nutzung eines Primers, ein Flächenwiderstand von 50 kΩ / □ erzielt.In particular, the coating by means of electrically conductive polymer, for. B. Polyethylendioxythiophenpolystyrolsulfonat (PEDT / PSS) in combination with a metallization layer is to be used as a technological hurdle for counterfeiters, whereby the PEDT / PSS characterized by a sheet resistance in the range of 15-100 kΩ / □. On PE films is achieved using a primer, a sheet resistance of 50 kΩ / □.

Die Polymerschicht wird flächenhaft oder partiell aufgetragen, wobei sie vorzugsweise flächenmoduliert oder als Streudruck appliziert wird. Auf Grund der sich partiell ändernden Flächenwiderstände entsteht eine lesbare Kodierung. Diese wiederum lässt sich problemlos auf unterschiedliche Art detektieren, insbesondere mittels kapazitiver Kopplung. Vorteilhaft ist eine mögliche maschinelle physikalische Zweifachprüfung des elektrisch leitenden Polymers PEDT/PSS, welche zum einen die elektrische Leitfähigkeit, zum anderen die optische Eigenschaft beispielsweise im IR-Bereich detektiert. Die IR-Eigenschaften sind mit steigender Wellenlänge (> 900 nm) sowie vom Auftragsgewicht bzw. der Schichtdicke effektiv nutzbar. Durch Absorption und Wellenlängenänderung sind messbare Kenngrößen gegeben. Durch diese Zweifachprüfung wird die Wahrscheinlichkeit der Identifikation von Fälschungen, bzw. die Fehlerrate der nicht erkannten Fälschungen oder aber auch die Fehlerrate der echten als Fälschung erkannten Produkte wesentlich verringert.The polymer layer is applied areally or partially, preferably surface modulated or applied as a scattering pressure. Due to the partially Changing surface resistances creates a readable coding. This in turn can be easily detect in different ways, in particular by means of capacitive coupling. Advantageous is a possible mechanical dual physical testing of the electrically conductive Polymers PEDT / PSS, which on the one hand, the electrical conductivity, on the other hand optical property detected, for example in the IR range. The IR properties are with increasing wavelength (> 900 nm) and the order weight or the layer thickness effectively available. By absorption and wavelength change measurable characteristics are given. This double check will increase the likelihood of identifying counterfeits, or the error rate of the unrecognized forgeries or else the error rate the genuine counterfeit products.

Eine erfindungsgemäß zu verwendende metallisierte Fläche - insbesondere mit hoher Brillanz, bei der davon auszugehen wäre, dass diese eine gute elektrische Leitfähigkeit besitzt, welche ein elektrisch leitendes Sicherheitsmerkmal beinhalten könnte oder aber selbst über kodierte Flächenwiderstandsänderungen ein Sicherheitsmerkmal darstellt - stellt eine weitere Hürde für einen Fälscher dar, da die Aufgabe, Funktion und Wirkungsweise der metallisierten Fläche weder zu vermuten noch offensichtlich sind. A metallized surface to be used according to the invention - in particular with high brilliance, which would be expected to have good electrical conductivity has, which could include an electrically conductive security feature or even itself represents a safety feature via coded surface resistance changes - provides a Another hurdle for a counterfeiter, since the task, function and operation of the metallized Surface neither to suspect nor are obvious.

Im Einzelnen betrifft die Erfindung Sicherheitsmerkmale, vorzugsweise Aufreißbänder bzw. -fäden, zur Identifikation der Originalität von Produkten durch den Hersteller oder befugte Kontrollorgane. Die Aufreißbänder bestehen aus Substraten, aus flächenhaft oder streuhaft metallisierten Applikationen mit einem definierten Flächenwiderstand und aus elektrisch leitenden Polymeren, ebenfalls mit einem definierten Flächenwiderstand. Gemäß der Erfindung ist der Flächenwiderstand der flächenhaft oder streuhaft metallisierten Applikationen größer als 200 kΩ / □, und der Flächenwiderstand von elektrisch leitenden Polymeren liegt in einer Größenordnung von 15 bis 100 kΩ / □. Die Differenz zwischen den Flächenwiderständen der Applikationen und der elektrisch leitenden Polymere ist größer als 100 kΩ / □. Diese Art erfindungsgemäßer Aufreißbänder wird mit Verpackungen verbunden.More particularly, the invention relates to security features, preferably tearing tapes threads to identify the originality of products by the manufacturer or authorized control bodies. The tear strips consist of substrates, of planar or streussaft metallized applications with a defined sheet resistance and out electrically conductive polymers, also with a defined sheet resistance.

Der Aufbau der Aufreißbänder - also die Anordnung von Substraten, elektrisch leitenden Polymeren, flächenhaft oder streuhaft metallisierten Applikationen, Schutzschichten, Trennmitteln und/oder Kleberschichten - wird je nach Bestimmung gewählt, wobei die einzelnen Schichten untereinander austauschbar sind. Als Trennmittel finden vorzugsweise silikonisierte Schichten oder aber Transferbänder bzw. -schichten Anwendung. Je nach Verwendungszweck und angewandter Herstellungstechnologie kommen Primer zum Einsatz, wobei die Primer sowohl als Haftvermittler dienen als auch gemäß der Erfindung zum Glätten von aufgetragenen Substraten geeignet sind. Die elektrisch leitenden Polymere, die flächenhaft oder streuhaft metallisierten Applikationen, die Substrate, gegebenenfalls auch die Schutzschichten und die Primer werden erfindungsgemäß als Kodiermittel so angeordnet, dass ihre elektrischen oder optischen oder magnetischen Wirkweisen mittels kapazitiver Kopplung detektierbar sind, also als Kodiermittel Anwendung finden.The structure of the tear strips - so the arrangement of substrates, electrically conducting polymers, planar or scattered metallized applications, protective coatings, Release agents and / or adhesive layers - is selected depending on the destination, wherein the individual layers are interchangeable. As a release agent find preferably siliconized layers or transfer tapes or layers application. Depending on Purpose and applied manufacturing technology are primers used, wherein the primers serve both as a primer and for smoothing according to the invention of coated substrates are suitable. The electrically conductive polymers, the areal or streuhaft metallized applications, the substrates, possibly also the Protective layers and the primers are arranged according to the invention as coding means, that their electrical or optical or magnetic effects by means of capacitive Coupling are detectable, so find application as coding.

Gemäß der Erfindung ist auch vorgesehen, die elektrisch leitenden Polymere partiell oder flächenmoduliert oder partiell-flächenmoduliert aufzutragen. Auch für diesen Fall ist eine daraus entstehende Kodierung kapazitiv detektierbar. Ebenso partiell oder flächenmoduliert oder partiell-flächenmoduliert applizierte flächenhaft oder streuhaft metallisierte Applikationen sind als Kodierung mittels kapazitiver Kopplung detektierbar.According to the invention is also provided, the electrically conductive polymers applied partially or surface modulated or partially surface modulated. Also for this Case is a resulting coding capacitive detectable. Also partial or surface modulated or partially-surface-modulated applied areally or scattered metallized applications can be detected as coding by means of capacitive coupling.

Gemäß der Erfindung sind die Kodiermittel der Sicherheitsmerkmale physikalisch oder chemisch beeinflussbar. Insbesondere durch Energiezuführung in Form von sichtbarem Licht, UV-, IR- oder Wärmestrahlung reagieren die Kodiermittel für den Prüfer wahrnehmbar als Echtheits- bzw. Originalitätsmerkmal entweder in den Aufreißbändern oder in Verbindung mit der Verpackung. Es liegt auch im Bereich der Erfindung, Reaktionsfarben als Kodiermittel zu verwenden, wobei die einzelnen Komponenten von Reaktionsfarben durch Kontaktierung miteinander reagieren und somit als Echtheits- bzw. Originalitätshinweis dienen. Das gemäß der Erfindung einzusetzende elektrisch leitende Polymer ist vorzugsweise ein Polyethylendioxythiophenpolystyrolsulfonat (PEDT/PSS).According to the invention, the coding means of the security features are physical or chemically influenced. In particular, by energy supply in the form of visible Light, UV, IR or thermal radiation react the coding for the examiner perceptible as authenticity or originality feature either in the tear strips or in Connection with the packaging. It is also within the scope of the invention, reaction colors as Coding to use, with the individual components of reaction colors through Contacting react with each other and thus serve as evidence of authenticity or originality. The electrically conductive polymer to be used according to the invention is preferably one Polyethylene dioxythiophene polystyrene sulfonate (PEDT / PSS).

Eine besondere Ausgestaltungsform der Erfindung sieht vor, Teilbänder zu einem Aufreißband zusammenzufügen. Die einzelnen Teilbänder können - wie bereits beschrieben - aus Substraten, aus flächenhaft oder streuhaft metallisierten Applikationen und aus elektrisch leitenden Polymeren bestehen, wobei die einzelnen Teilbänder ebenfalls aus Schutzschichten, Trennmittelschichten, Kleberschichten und einem Primer bestehen können. Die Auswahl und Anordnung der einzelnen Schichten richtet sich nach der gewünschten Verwendung und nach der Verarbeitungstechnologie. Unterschiedliche Flächenwiderstände einzelner Schichten in den Teilbändern liegen auch hier im Bereich der Erfindung. Die gleich oder mit unterschiedlichem Aufbau hergestellten Teilbänder ergeben für sich allein oder aber nach ihrer Verbindung zu einem Aufreißband Kodierungen. Werden Kodierungen erst durch die Zusammenfügung von Teilbändern gebildet, so ist deren passgenaue Zusammenbringung eine wesentliche Voraussetzung. Sämtliche Kodiermittel auf den Teilbändern und auf dem Aufreißband können auf der aufzubringenden Fläche unterschiedlich ausgerichtet sein.A particular embodiment of the invention provides for subbands to put together a tear tape. The individual subbands can - as already described - Of substrates, of areal or scattered metallized applications and consist of electrically conductive polymers, wherein the individual subbands also made Protective layers, release coatings, adhesive layers and a primer can exist. The selection and arrangement of the individual layers depends on the desired Use and after the processing technology. Different surface resistances individual layers in the subbands are also within the scope of the invention. The same or produced with different structure sub-bands result on their own or in addition after their connection to a tear tape encodings. Be coded first the assembly of subbands formed, so is their tailor-made Zusammenbringung an essential requirement. All coding on the subbands and on the Tear tape can be aligned differently on the surface to be applied.

Beispiel 1:Example 1:

In Figur 1 ist ein Produkt in Folienverpackung 2 mit Aufreißband 1, welches mit der Folienverpackung 2 beispielsweise verpresst, verklebt oder gesiegelt ist, dargestellt. Das Aufreißband 1 ist üblicherweise als Flachfolie ausgebildet, die stärker ist als die Folienverpackung 2. Verwendung finden Aufreißfäden 1, die eine Dicke von ca. 30-50 µm und eine Breite von 1 mm bis 2 mm aufweisen. Zur besseren Kenntlichmachung ist das Aufreißband 1 häufig farblich gestaltet und hebt sich somit von der Folienverpackung 2 deutlich ab. Zum Greifen des Aufreißbandes 1 ist dieses am Anfang über die Folienverpackung 2 hinausstehend als Lasche 3 ausgebildet. In der Figur 1b ist ein erfindungsgemäßes Aufreißband 1 zur Identifikation der Originalität durch den Hersteller oder befugte Kontrollorgane schematisch als Teilstück dargestellt. Es enthält im Wesentlichen ein Substrat 10, eine flächen- oder streuhaft metallisierte Applikation bzw. Applikationsschicht 13 und ein elektrisch leitendes Polymer 12 mit einem Flächenwiderstand in der Größenordnung von 15-100 kΩ / □, wobei die Differenz zwischen dem Flächenwiderstand der flächen- oder streuhaft metallisierten Schicht 13 und dem Flächenwiderstand des elektrisch leitenden Polymers 12 größer als 100 kΩ / □ ist. Die Schichten sind wahlweise austauschbar.FIG. 1 shows a product in film packaging 2 with a tear strip 1 which is pressed, glued or sealed, for example, with the film package 2 . The tear tape 1 is usually formed as a flat film, which is stronger than the film package 2. Use find tear threads 1 , which have a thickness of about 30-50 microns and a width of 1 mm to 2 mm. For better identification, the tear tape 1 is often colored and thus stands out clearly from the film package 2 . To grasp the tear strip 1 this is at the beginning on the film packaging 2 protruding formed as a tab 3 . In FIG. 1 b, a tearing strip 1 according to the invention for identification of the originality by the manufacturer or authorized inspection bodies is shown schematically as a section. It essentially contains a substrate 10, an areal or scattered metallized application or application layer 13 and an electrically conductive polymer 12 having a sheet resistance of the order of 15-100 kΩ / □, wherein the difference between the sheet resistance of the surface or scattered metallized layer 13 and the sheet resistance of the electrically conductive polymer 12 is greater than 100 kΩ / □. The layers are optionally interchangeable.

Beispiel 2:Example 2:

In diesem Ausführungsbeispiel ist das Substrat 10 mit einer flächenhaft metallisierten Schicht 13 mit einem Flächenwiderstand größer als 200 kΩ / □ versehen. Das humanvisuell nicht sichtbare elektrisch leitende Polymer 12 - hier ein Polyethylendioxythiophenpolystyrolsulfonat - gibt hier den Hersteller und das Herstellungsdatum an und ist in Figur 1c dargestellt.In this exemplary embodiment, the substrate 10 is provided with a planar metallized layer 13 with a sheet resistance greater than 200 kΩ / □. The electrically non-visible electrically conductive polymer 12 - here a Polyethylendioxythiophenpolystyrolsulfonat - indicates here the manufacturer and the date of manufacture and is shown in Figure 1c.

Beispiel 3:Example 3:

Figur 2a stellt eine weitere Variante des Aufreißbands 1 dar. Ein Substrat 10 ist mit einem Primer 11 geglättet. Auf diesem befindet sich das elektrisch leitende Polymer 12, welches wiederum falls notwendig mit einem Primer 11 versehen ist. Darauf folgt die metallisierte Schicht 13 und falls anwendungsbedingt gewünscht eine abschließende Schutzschicht 14, wobei auch zwischen der metallisierten Schicht 13 und der Schutzschicht 14 ein Primer 11 erforderlich sein kann. Auf der Schutzschicht 14 kann auch ein farblicher Lack - in der Figur 2a nicht dargestellt - zur optischen Veredelung aufgetragen sein. Es ist auch denkbar, dass die Schutzschicht 14 aus einer solchen Lackschicht besteht. Die Lage des elektrisch leitenden Polymers 12 kann mit der metallisierten Schicht 13 vertauscht werden. Die verwendeten Primer 11 können jeweils auch als Haftvermittler wirken. Zusätzlich enthält das Aufreißband 1 eine Kleberschicht 15 zur Verbindung mit der Folienverpackung 2. Wird das Aufreißband 1 mit der Folienverpackung 2 verpresst oder gesiegelt, kann auf die Kleberschicht 15 verzichtet werden. Da das Aufreißband 1 meist auf Rollen gewickelt wird, ist es sinnvoll, eine Seite dessen mit einem Trennmittel 9, insbesondere einem Silikonfilm, zu versehen. Als Trennmittel 9 kann das Aufreißband 1 auch mit einem Transferband 16 (Figur 2c) versehen werden, wobei das Transferband 16 Justagemittel 8, beispielsweise Perforationen, Magnetspuren oder optische Marken zum positionsgenauen Applizieren des Aufreißbandes 1 auf der Folienverpackung 2 enthält.FIG. 2 a shows another variant of the tear tape 1. A substrate 10 is smoothed with a primer 11 . On this is the electrically conductive polymer 12, which in turn is provided with a primer 11 if necessary. This is followed by the metallized layer 13 and, if required by application, a final protective layer 14, wherein a primer 11 may also be required between the metallized layer 13 and the protective layer 14 . On the protective layer 14 may also be a color paint - not shown in the figure 2a - be applied for optical finishing. It is also conceivable that the protective layer 14 consists of such a lacquer layer. The position of the electrically conductive polymer 12 can be interchanged with the metallized layer 13 . The primers 11 used can each also act as adhesion promoters. In addition, the tear tape 1 contains an adhesive layer 15 for connection to the film package 2. If the tear tape 1 is pressed or sealed with the film package 2 , the adhesive layer 15 can be dispensed with. Since the tear tape 1 is usually wound on rollers, it makes sense to provide one side of it with a release agent 9, in particular a silicone film. As a release agent 9 , the tear strip 1 can also be provided with a transfer belt 16 (FIG. 2c), the transfer belt 16 containing adjustment means 8, for example perforations, magnetic tracks or optical marks for the positionally accurate application of the tear strip 1 on the film package 2 .

Beispiel 4:Example 4:

In Abwandlung des Beispiels 3 ist in dieser Ausgestaltungsform - dargestellt in Figur 2b - das Substrat 10 beidseitig beschichtet, wobei auf der einen Seite des Substrats 10 sich ein elektrisch leitendes Polymer 12 und auf der anderen Seite die metallisierte Schicht 13 befindet.In a modification of Example 3, in this embodiment - shown in Figure 2b - the substrate 10 coated on both sides, wherein on one side of the substrate 10 , an electrically conductive polymer 12 and on the other side, the metallized layer 13 is located.

Beispiel 5:Example 5:

Eine weitere Variante zeigt Fig. 2c. Zwei Teilbänder 30; 31 werden unabhängig voneinander hergestellt und miteinander verbunden. Die Teilbänder 30; 31 sind beispielsweise verklebt oder verpresst oder gesiegelt und bilden zusammengefügt das Aufreißband 1. Das eine Teilband 30 besteht neben anderen Schichten aus einem Substrat 10 und dem elektrisch leitenden Polymer 12 und das andere Teilband 31 im Wesentlichen aus einem Substrat 10 und der metallisierten Schicht 13 besteht. Je nach beabsichtigter künftiger Verwendung und je nach technologischen Möglichkeiten sind die wesentlichen Schichten der Teilbänder 30; 31 untereinander austauschbar und die Teilbänder 30;31 sind an unterschiedlichen Stellen zusammenfügbar.Another variant is shown in FIG. 2c. Two subbands 30; 31 are manufactured and connected independently of each other. The subbands 30; 31 are, for example glued or pressed or sealed and together form the tear strip 1. The one sub-strip 30 consists, among other layers of a substrate 10 and the electrically conductive polymer 12 and the other sub-band 31 consists essentially of a substrate 10 and the metallized layer 13 , Depending on the intended future use and depending on technological possibilities, the essential layers of the sub-bands 30; 31 interchangeable and the subbands 30, 31 are joined together at different locations.

Beispiel 6:Example 6:

In einer weiteren Ausgestaltungsform des Aufreißbandes 1 bzw. der Teilbänder 30; 31 ist das elektrisch leitende Polymer 12 flächenmoduliert appliziert. Die Figur 3a verdeutlicht den schematischen Aufbau eines Teilstücks eines Aufreißbandes 1. Auf Grund der unterschiedlichen Auftragsstärke und der sich daraus ergebenden sich ändernden Flächenwiderstände entsteht eine Kodierung. In diesem Ausführungsbeispiel repräsentieren die modulierten Flächenwiderstände eine spezifische Kodierung des Herstellers. (hierzu Figur 3a)In a further embodiment of the tear strip 1 or the subbands 30; 31 , the electrically conductive polymer 12 is applied surface modulated. FIG. 3 a illustrates the schematic structure of a section of a tear strip 1. Due to the different application thickness and the resulting surface resistances, this results in coding. In this embodiment, the modulated sheet resistances represent a specific coding of the manufacturer. (see FIG. 3a)

Beispiel 7:Example 7:

Dieses Beispiel beschreibt ein Aufreißband 1 bzw. Teilbänder 30; 31 ähnlich dem in Beispiel 6 beschriebenen, wobei das elektrisch leitende Polymer 12 partiell aufgetragen ist. Wie in Figur 3b dargestellt, ergeben die partiellen Aufträge von Polymer 12 partiell sich ändernde Flächenwiderstände, die wiederum als Kodierungen dienen und Produktionsdaten wie logistische Wege, Chargen, Bestimmungsorte, Produktklassen oder Seriennummem darstellen können.This example describes a tear strip 1 or subbands 30; 31 similar to that described in Example 6, wherein the electrically conductive polymer 12 is partially applied. As shown in FIG. 3b, the partial orders of polymer 12 result in partially varying surface resistances, which in turn serve as codes and can represent production data such as logistical routes, batches, destinations, product classes or serial numbers.

Beispiel 8:Example 8:

Variiert aus den Beispielen 6 und 7 wird anhand der Figur 3c eine weitere Ausgestaltungsform des Aufreißbandes 1 bzw. der Teilbänder 30; 31 vorgestellt. Das elektrisch leitende Polymer 12 ist partiell aufgetragen, und die jeweiligen Abschnitte der partiellen Aufträge sind flächenmoduliert appliziert. Auf Grund der sich dadurch partiell ändernden Flächenwiderstände entsteht eine Kodierung, welche den Hersteller und das Herstellungsdatum und durch die flächenmodulierten Abschnitte entsteht eine Kodierung, welche eine spezifische Kodierung des Herstellers repräsentieren.Varying from examples 6 and 7, with reference to FIG. 3c, a further embodiment of the tear strip 1 or of the subbands 30; 31 presented. The electrically conductive polymer 12 is partially applied, and the respective sections of the partial jobs are applied surface modulated. Due to the thereby partially changing surface resistances, a coding is produced which represents the manufacturer and the date of manufacture and by the area-modulated sections a coding representing a specific coding of the manufacturer.

Beispiel 9:Example 9:

Nach diesem Ausführungsbeispiel werden eine oder mehrere Kodierungen kombiniert nach den Beispielen 6, 7 und/oder 8 vorgeschlagen, wobei diese in unterschiedlichen Flächenrichtungen realisiert werden. So wird beispielsweise das elektrisch leitende Polymer 12 in einer Flächenrichtung partiell-flächerunoduliert - siehe Beispiel 8 - aufgetragen und in einer anderen Flächenrichtung partiell - siehe Beispiel 7 - appliziert, wobei in beiden Richtungen unterschiedliche Kodierungen entstehen.According to this embodiment, one or more codes are combined according to the examples 6, 7 and / or 8 proposed, wherein these are realized in different surface directions. Thus, for example, the electrically conductive polymer 12 in a surface direction partially planar-ununulated - see Example 8 - applied and partially in another area direction - see Example 7 - applied, with different codings in both directions.

Beispiel 10:Example 10:

In einer weiteren Ausgestaltungsform des Aufreißbandes 1 bzw. der Teilbänder 30; 31 wird ein Primer 11, wie das elektrisch leitendes Polymer 12 in den Beispielen 6 bis 9, partiell oder flächenmoduliert oder partiell-flächenmoduliert aufgetragen. Die dadurch entstehende Struktur des Primerauftrags 11 überträgt sich als Masterstruktur auf die aufzubringende Schicht aus elektrisch leitendendem Polymer 12 und/oder eine metallisierte Schicht 13. Es entstehen Kodierungen wie in den Beispielen 6 bis 9 beschrieben.In a further embodiment of the tear strip 1 or the subbands 30; 31 , a primer 11, such as the electrically conductive polymer 12 in Examples 6 to 9, is applied partially or surface modulated or partially surface modulated. The resulting structure of the primer application 11 is transferred as a master structure to the applied layer of electrically conductive polymer 12 and / or a metallized layer 13. Encoding results as described in Examples 6 to 9.

Beispiel 11:Example 11:

Figur 4a zeigt einen üblichen Warenfluss- bzw. Verteilerweg für ein Aufreißband 1. Ein autorisierter Hersteller von Sicherheitsmerkmalen stellt das Aufreißband 1 her und liefert dies dem Verpacker. Die Möglichkeiten für Produktpiraten oder unautorisierte Produzenten, an dieses Aufreißband 1 zu gelangen, sind vielfältig und für den Kontrollierenden leider oft nicht nachvollziehbar. Gemäß der Darstellung in Figur 4a wird das Original-Aufreißband 1 beispielsweise während des Transports zum Verpacker "abgezweigt". In Figur 4b ist in getrennter Logistik ein Warenfluss wie durch Anwendung des erfindungsgemäßen Aufreißbandes 1, bestehend aus zwei oder mehreren Komponenten, dargestellt. Zwei Hersteller von Fadenkomponenten stellen Teile eines Aufreißbandes 1 her und liefern diese dem Verpacker. Diese Teilbänder 30; 31 werden vorzugsweise mit üblichen Transferverfahren - dargestellt in Figur 5 - erst beim Verpacker miteinander verbunden und stellen jedes für sich Kodierungen oder durch die Kombination miteinander Kodierungen dar. Vorteilhafterweise sollten die Teilbänder 30; 31 oder die Kombination der Teilbänder 30; 31 kompatibel zu den üblichen Anlagen sein. Die Dicke der einzelnen Teilbänder 30; 31 ist so zu wählen, dass die Gesamtdicke des Aufreißbands 1 die üblicherweise verwendete Dicke von 30-50 µm nicht übersteigt. Durch die Kombination wird eine weitaus höhere Sicherheitsstufe erreicht, da zwei Komponenten über verschiedene Verteilerwege zum Anwender gelangen. Durch die zwei getrennt gelieferten Komponenten entsteht eine sehr hohe Schwelle für Fälscher und Kriminelle oder unautorisierte Produzenten und ist in Fig. 4 b durch unterbrochene Pfeile dargestellt. Wie bereits oben erläutert, kann jedes Teilband 30; 31 für sich oder aber die Kombination der Teilbänder 30; 31 eine Kodierung darstellen. Aus der Kombination zweier Teilbänder 30; 31 entsteht ein kodiertes Aufreißband 1. Die Entstehung der Kodierung ist in Figur 6 dargestellt. Erst durch das passgenaue Zusammenbringen beider Teilbänder 30; 31 entsteht die gewünschte Kodierung, welche die Originalität des Produkts repräsentiert. Verschiedene Kodierungsversionen sind durch gezielten Versatz beim Zusammenbringen beider Teilbänder 30; 31 zu erzielen. Die einzelnen Kodiermittel können verschiedene, vorzugsweise elektrische, magnetische, optische Wirkweisen besitzen. Durch ihre Anzahl, Anordnung, Geometrie und Eigenschaften oder deren Kombination entstehen für den Prüfer detektierbare Kodierungen. In diesem Ausführungsbeispiel stellt die Kodierung des Teilbandes 30 den Produktionsstandort 20 und die Kodierung des Teilbandes 31 die Produktionsdaten 21 dar.Figure 4a shows a common flow path for a tearing tape 1. An authorized manufacturer of security features manufactures the tearing tape 1 and provides it to the packer. The possibilities for product pirates or unauthorized producers to access this booklet 1 are manifold and unfortunately often incomprehensible to the controlling party. As shown in Figure 4a, the original tear tape 1 is "branched off" during transport to the packer, for example. FIG. 4b shows in separate logistics a flow of goods as by the use of the tearing strip 1 according to the invention , consisting of two or more components. Two yarn component manufacturers make parts of a tear tape 1 and deliver it to the packer. These subbands 30; 31 are preferably connected to one another by the usual methods of transfer - shown in Figure 5 - only at the packer and represent each by itself coding or by the combination of codings. Advantageously, the sub-bands 30; 31 or the combination of subbands 30; 31 compatible with the usual systems. The thickness of the individual subbands 30; 31 is to be chosen so that the total thickness of the tearing strip 1 does not exceed the commonly used thickness of 30-50 microns. The combination achieves a much higher level of security since two components reach the user via different distribution channels. The two separately supplied components create a very high threshold for counterfeiters and criminals or unauthorized producers and is shown in FIG. 4 b by broken arrows. As already explained above, each sub-band 30; 31 alone or the combination of subbands 30; 31 represent a coding. From the combination of two sub-bands 30; 31 creates a coded tear tape 1. The origin of the coding is shown in FIG. Only through the accurate matching of the two sub-bands 30; 31 produces the desired coding, which represents the originality of the product. Different coding versions are by targeted offset when bringing together both sub-bands 30; 31 to achieve. The individual coding means can have different, preferably electrical, magnetic, optical effects. Due to their number, arrangement, geometry and properties or their combination detectable detections arise for the examiner. In this embodiment, the coding of the sub-band 30, the production site 20 and the coding of the sub-band 31, the production data 21 represents.

Beispiel 12:Example 12:

In Abwandlung zu Beispiel 11 sind in dieser bevorzugten Ausführungsvariante die Kodierungen des einzelnen Teilbandes 30; 31 unvollständig und ergeben erst in Kombination ein Aufreißband 1 mit einer entschlüsselbaren bzw. detektierbaren Kodierung. Insbesondere können die einzelnen Teilbänder 30; 31 auch Kodiermittel besitzen, welche physikalisch beeinflussbar sind, beispielsweise durch Energiezuführung, insbesondere in Form von sichtbarem Licht, UV- , IR- oder Wärmestrahlung oder aber auch durch chemische Beeinflussung. Es liegt auch im Bereich der Erfindung, die einzelnen Teilbänder 30;31 mit Komponenten einer Reaktionsfarbe zu versehen, welche bei Kontakt miteinander reagieren.In a modification to Example 11 are in this preferred embodiment, the coding of the individual sub-band 30; 31 incomplete and give only in combination a tear tape 1 with a decipherable or detectable coding. In particular, the individual sub-bands 30; 31 also have coding, which are physically influenced, for example by energy supply, in particular in the form of visible light, UV, IR or heat radiation or else by chemical influence. It is also within the scope of the invention to provide the individual subbands 30, 31 with components of a reaction dye which react upon contact with one another.

Beispiel 13:Example 13:

Unter Anwendung der in den Beispielen beschriebenen Varianten wird eine Kodierung erst durch das Verbinden eines Aufreißbandes 1 mit einer Verpackung aktiviert. Es entsteht eine entschlüsselbare bzw. detektierbare Kodierung durch Kombination des Aufreißbandes 1 mit Markierungen der Verpackung, beispielsweise durch die positionsgenaue Verbindung des Aufreißbandes 1 mit einer Folienverpackung 2. Using the variants described in the examples, coding is activated only by connecting a tearing strip 1 to a package. The result is a decipherable or detectable coding by combining the tear strip 1 with markings of the packaging, for example, by the positionally accurate connection of the tear strip 1 with a film package . 2
