Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur elektronischen Sicherung eines Artikels gegen Diebstahl gemäß dem Oberbegriff des Anspruchs 1 bzw. 7, dessen Merkmale aus der EP-A-0 619 243 bekannt sind. The invention relates to an apparatus and a method for securing an electronic article against theft according to the preamble of claim 1 and 7, the characteristics of which are known from EP-A 0 619 243rd

Es sind bereits unterschiedlichste Sicherungselemente zur elektronischen Sicherung von Artikeln gegen Diebstahl bekannt geworden. There are a wide variety of security elements for the electronic securing articles against theft became known. Eine besonders vorteilhafte Ausgestaltung eines Sicherungselementes in Form eines "Thin Film"-Etiketts wird in der EP 0 295 028 B1 beschrieben. A particularly advantageous embodiment of a fuse element in the form of a "thin film" -Etiketts is described in EP 0295028 B1. "Thin Film"-Etiketten bestehen aus einer dünnen, vorzugsweise im µm-Bereich liegenden Schicht aus weichmagnetischem Material. "Thin film" labels consist of a thin, preferably in the micron range underlying layer of soft magnetic material. Die weichmagnetische Schicht wird vorzugsweise mittels eines physikalischen Abscheideverfahrens unter Vakuumbedingungen auf ein Trägersubstrat aufgebracht. The soft magnetic layer is preferably applied to a carrier substrate by means of a physical deposition process under vacuum conditions.

Neben den "Thin Film"-Etiketten werden insbesondere zur Artikelsicherung im Lebensmittelbereich die sog. "Strip"-Sicherungselemente eingesetzt, die aus einem streifenförmigen, weichmagnetischen Material bzw. aus einem weichmagnetischen Draht bestehen. In addition to the "thin film" labels, the so-called. "Strip" -Sicherungselemente be used in particular for article surveillance in the food industry, which consist of a strip-like soft magnetic material or of a soft magnetic wire.

Weiterhin werden bei der Artikelsicherung Resonanzschwingkreise als Sicherungselemente eingesetzt. Furthermore, in the article surveillance resonant circuits are used as securing elements. Derartige Sicherungselemente sind zB in der EP 285 559 B1 ausführlich beschrieben. Such security elements are described in detail for example in EP 285 559 B1. Aus der EP 0 093 281 B1 sind Sicherungselemente bekannt geworden, die bei Anlegen eines magnetischen Wechselfeldes in mechanische Schwingungen versetzt werden und ein detektierbares Signal erzeugen. From EP 0093281 B1 securing elements are known, which are displaced upon application of an alternating magnetic field into mechanical vibrations and produce a detectable signal.

Aus der EP 0 494 114 A2 sind darüber hinaus sog. 'intelligente' Transponder bekannt geworden, die neben der Sicherung der Ware, an der sie befestigt sind, auch die Möglichkeit eröffnen, die betreffende Ware eindeutig zu identifizieren. EP 0494114 A2 'intelligent' transponders are furthermore known. Known that open in addition to securing the goods to which they are attached, and the ability to identify the goods in question clearly. In dieser Patentschrift ist auch der Aufbau eines entsprechenden Detektionssystems beschrieben. In this specification and the construction of a corresponding detection system is described.

Zur Detektierung von Sicherungselementen in einer Abfragezone sind eine Vielzahl unterschiedlicher Verfahren bekannt geworden. For the detection of security elements in an interrogation zone have been known a variety of different methods. So wird in der EP 123 586 B vorgeschlagen, zusätzlich zu zwei Abfragefelder mit den Frequenzen f1 und f2 im kHz-Bereich ein Feld mit einer im Hz-Bereich liegenden Frequenz in die Abfragezone zu senden. Thus, EP 123 586 B it is proposed, in addition to two interrogation fields with the frequencies f1 and f2 in the kHz range, a field transmit at a frequency lying in the range Hz in the interrogation zone to. Die beiden Abfragefelder mit den Frequenzen f1 und f2 regen ein in der Abfragezone befindliches Sicherungselement zur Aussendung eines charakteristischen Signals mit den Intermodulationsfrequenzen n•f1 ± m•f2 (n, m = 0, 1, 2,...) an. The two interrogation fields with the frequencies f1 and f2 excite a in the interrogation zone securing element to emit a characteristic signal with the intermodulation frequencies n • f1 ± m • f2 (n, m = 0, 1, 2, ...) to. Das niederfrequente Abfragefeld bewirkt, daß das Sicherungselement im Takt dieses Feldes von der Sättigung in eine Richtung zur Sättigung in die andere Richtung getrieben wird. The low-frequency interrogation field causes the fuse element to the beat of this field is driven from saturation in one direction to saturation in the other direction. Das charakteristische Signal tritt daher periodisch mit der Frequenz des niederfrequenten Feldes auf. Therefore, the characteristic signal occurs periodically with the frequency of the low-frequency field.

Als alternative Lösung ist auch bekannt geworden, lediglich ein im kHz-Bereich liegendes Abfragefeld zur Erregung des Sicherungselementes zu verwenden, wobei das charakteristische Signal des Sicherungselementes wiederum im Takte eines niederfrequenten Feldes, das das weichmagnetische Material zwischen den beiden Sättigungen hin- und hertreibt, auftritt. As an alternative solution is also known, only an in-kHz range interrogation field for excitation of the fuse element to be used, wherein the characteristic signal of the security element, in turn, in time with a low frequency field, which back the soft magnetic material between the two saturations and hertreibt occurs ,

Zur Detektion von Sicherungselementen mit Resonanzschwingkreisen wird ein schmalbandiges Wechselfeld in die Abfragezone abgestrahlt, das das Sicherungselement zur Aussendung eines charakteristischen Signals im Bereich seiner Resonanzfrequenz anregt. For the detection of security elements with resonant circuits a narrow-band alternating field is radiated into the interrogation zone that excites the securing element to emit a characteristic signal in the region of its resonant frequency.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung bzw. ein Verfahren vorzuschlagen, die bzw. das das Entfernen eines Sicherungselementes von einem gesicherten Artikel erheblich erschwert. The invention has the object of proposing a device and a process machine or considerably more difficult the removal of a fuse element of a secured item.

Die Aufgabe wird hinsichtlich der Vorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. The object is achieved by the characterizing features of claim 1 concerning the apparatus.

Gemäß vorteilhafter Weiterbildungen der erfindungsgemäßen Vorrichtung handelt es sich bei dem Sicherungselement um einen Streifen oder einen Dünnfilm aus einem weichmagnetischen Material oder um einen Resonanzschwingkreis, der die Kapazität C, den Widerstand R und die Induktivität L besitzt oder um ein magnetomechanisches Sicherungselement, das durch ein magnetisches Wechselfeld zu mechanischen Schwingungen angeregt wird. According to advantageous further developments of the inventive device is the security element is a strip or a thin film of a soft magnetic material or a resonant circuit having the capacitance C, the resistance R and the inductance L or a magneto mechanical securing element, the magnetic through a alternating field is excited to mechanical vibrations.

Es hat sich als äußerst günstig erwiesen, als Schutzfolie eine sich bei Temperaturänderungen zusammenziehende Folie (Schrumpffolie) zu verwenden. It has proven to be extremely convenient to use as a protective film, a contractile changes in temperature film (shrink film). Derartige Folien sind wohlbekannt und dienen ua dazu, einen Artikel gegen Beschädigungen zu schützen. Such films are well known and serve, inter alia, to protect an article against damage. Eine breite Anwendung finden sie auch dort, wo es gilt, Produkte vor unbefugtem Öffnen zu schützen. they are widely used even where it is necessary to protect products against unauthorized opening. Hierdurch wird insbesondere bei Verpackungen, die hochwertige Produkten enthalten, sichergestellt, daß kein Austausch oder Vermischen des Orginalproduktes erfolgen kann. In this way, it is ensured especially with packages contain high-quality products that no exchange or mixing can take place of the original product.

Erfindungsgemäß erfüllen die Schutzfolien noch die zusätzliche Funktion, das Sicherungselement mit dem zu sichernden Artikel zu verbinden und jedwede Manipulationen an dem Sicherungselement auf einfache Weise, aber dennoch äußerst wirkungsvoll zu verhindern. According to the protective films still fulfill the additional function of the safety element with the secured items to connect and any tampering with the security element in a simple way, but to prevent extremely effective. Durch die erfindungsgemäße Vorrichtung wird durch eine geeignete Plazierung des Sicherungselementes und eine nachfolgende Sicherung mittels der Schutzfolie erreicht, daß der gesicherte und geschützte Artikel nicht vor dem Kauf geöffnet wird. The inventive device of the fuse element and a subsequent backup is achieved by means of the protective film that the secure and protected item will not be opened before purchase by a suitable placement. Dadurch wird den hohen Anforderungen an die Hygiene beim Verkauf von Lebensmitteln, aber insbesondere beim Verkauf von kosmetischen Produkten (Cremedosen, Lippenstifte, usw.) Rechnung getragen. This is the high hygiene requirements in the sale of food, but particularly attributable to the sale of cosmetic products (cream jars, lipsticks, etc.) into account. Weiterhin wird dadurch, daß das Sicherungselement mittels der Schutzfolie an dem Artikel befestigt ist, dessen unerlaubtes Entfernen von dem Artikel erheblich erschwert. Furthermore, the fact that the securing element is secured by means of the protective film to the article, considerably complicates the unauthorized removal of the article.

Entweder wird die Folie nach dem Anbringen auf dem Artikel erhitzt oder sie wird schon in erhitztem Zustand um den Artikel gewickelt. Either the film is heated from the article after the application or it is wound around the article already in a heated state. Bei Erkalten schrumpft sie zusammen und paßt sich der Form des zu schützenden Artikels optimal an. When cooled, it shrinks and shape of the article to be protected adapts to optimal.

Als besonders vorteilhaft ist es anzusehen, wenn die Schutzfolie als Laminat vorliegt, wobei die Sicherungselemente in dem Laminat eingebettet und vorzugsweise in zueinander parallel liegenden Bereichen angeordnet sind. Especially advantageous is to see if the protective film is present as a laminate, wherein the security elements embedded in the laminate and preferably arranged in mutually parallel areas. Durch Unterteilung des Laminats läßt sich die Größe der Schutzfolie problemlos auf die Größe des zu sichernden Artikels abstimmen. By dividing the laminate, the size of the protective film can easily tune the size of the secured article.

Die Aufgabe wird hinsichtlich des Verfahrens durch die kennzeichnenden Merkmale des Anspruchs 7 gelost. The object is achieved as regards the method by the characterizing features of claim 7. Gemäß einer ersten Möglichkeit, wird das Sicherungselement mit dem Artikel verbunden, zB aufgelegt oder aufgeklebt; According to a first possibility, the securing element with the article, for example, is connected, applied or glued; nachfolgend wird die Schutzfolie zumindest im Bereich des Sicherungselementes um den Artikel gewickelt oder auf den Artikel aufgezogen. the protective film is below at least in the region of the fuse element wrapped around the article or applied to the article.

Bei dem erfindungsgemäßen Verfahren wird vorgeschlagen, das Sicherungselement mit der Schutzfolie zu verbinden; In the inventive method it is proposed to connect the securing element with the protective film; anschließend wird die Schutzfolie um den Artikel gewickelt oder auf den Artikel aufgezogen, so daß sich auch hier das Sicherungselement zwischen Artikel und Schutzfolie befindet. then the protective film is wrapped around the article or applied to the article, so that also here the securing element between the article and sealing tape. Hierbei ist es besonders günstig, wenn die Schutzfolie mit den integrierten Sicherungselementen als Laminat hergestellt wird, wobei die Sicherungselemente parallel zueinander angeordnet sind; It is particularly advantageous if the protective film is made with the integrated fuse elements as a laminate, wherein the securing elements are arranged parallel to each other; nachfolgend wird das Laminat in Abhängigkeit von dem zu sichernden Artikel auf die benötigte Größe geschnitten. the laminate depending on the item to be secured to the desired size is cut below.

Durch die Ausbildung des Sicherungselements als integralen Bestandteil der Schutzfolie wird das Anbringen des Sicherungselementes und der Schutzfolie an dem Artikel erheblich erleichtert, da keine separaten Teile mehr gehandhabt werden müssen. Due to the design of the fuse element as an integral part of the protective sheet mounting the fuse element and the protective film on the article is made much easier because no separate parts need to be handled more.
