Description

Transponder-EtikettTransponder label
Beschreibungdescription
Die Erfindung betrifft ein Transponder-Etikett gemäß den Oberbegriffen der unabhängigen Ansprüche 1 und 4.The invention relates to a transponder label according to the preambles of independent claims 1 and 4.
Transponder-Etiketten dienen zur Kennzeichnung von Gegenständen.Transponder labels are used to identify objects.
Transponder sind passive, ohne eine Energieversorgung ausgeführte elektronische Chips, die von einem Transponder-Lesegerät elektromagnetisch erregt und auf elektromagnetischem Wege eine gespeicherte Information abgeben. Transponderchips weisen eine flache Gestalt mit kleinen Abmessungen auf, die es gestattet, sie innerhalb von Etiketten anzuordnen. In vielen Fällen werden Transponder-Etiketten so ausgeführt, daß sie vor oder nach dem Aufkleben bedruckbar sind.Transponders are passive electronic chips, which are designed without a power supply and which are electromagnetically excited by a transponder reader and emit stored information by electromagnetic means. Transponder chips have a flat shape with small dimensions, which allows them to be arranged within labels. In many cases, transponder labels are designed so that they can be printed before or after they are attached.
Bei dem Druckvorgang, beispielsweise mittels eines Thermotransferdruckers, stört jegliches Hervorstehen des Chips. Durch ein auch nur geringfügiges Hervorstehen des Chips hebt nämlich der Druckkopf an der Stelle des Chips etwas von dem Etikett ab, so daß im Bereich des Chips nicht bedruckte Flächen auf dem Transponder- Etikett entstehen können. Daher sollen Transponder- Etiketten eine möglichst ebene Oberfläche ohne auch nur geringfügig hervorstehende Bereiche aufweisen.Any protrusion of the chip interferes with the printing process, for example by means of a thermal transfer printer. Because the chip protrudes even slightly, the print head lifts something off the label at the location of the chip, so that unprinted areas can appear on the transponder label in the area of the chip. Therefore, transponder labels should have a surface that is as flat as possible, without even slightly protruding areas.
Aus der DE 200 18 648 Ul geht ein Transponder-Etikett mit einer bedruckbaren Oberfolie und einer Chipeinlage hervor, die in einer Erhebung einen elektronischen Transponderchip enthält, und mit einem von einer Kleberschicht an der Unterseite abziehbaren Trägerblatt. Dieses Transponder-Etikett ist dadurch gekennzeichnet, daß die Chipeinlage auf ihrer die Erhebung aufweisenden Seite mit einer Zwischenlage verbunden ist, die im Bereich der Erhebung eine Aussparung aufweist, deren Tiefe mindestens angenähert der Höhe der Erhebung entspricht. Durch den in der Erhebung angeordneten Transponderchip und durch die auf die Erhebung angepaßte Zwischenschicht, die zwischen der Oberfolie und dem Träger angeordnet ist, wird eine weitestgehend ebene, bedruckbare Oberfläche des Transponder-Etiketts erreicht. Nachteilig bei diesem Transponder-Etikett ist der aufwendige Aufbau. So muß nicht nur der Transponderchip in einer eigens dafür vorgesehenen Erhebung der Chipeinlage angeordnet sein, es ist zudem erforderlich die Zwischenlage auf diese Erhebung anzupassen. Die Erhebung und die Zwischenlage weisen außerdem eine Dicke auf, die einem sehr flachen und damit im aufgeklebten Zustand des Transponder-Etiketts wenig störenden Aufbau des Transponder-Etiketts entgegensteht.DE 200 18 648 Ul discloses a transponder label with a printable top film and a chip insert, which contains an electronic transponder chip in a survey, and with a carrier sheet that can be peeled off from an adhesive layer on the underside. This transponder label is characterized in that the chip insert is connected on its side having the elevation to an intermediate layer which has a recess in the area of the elevation, the depth of which corresponds at least approximately to the height of the elevation. A largely flat, printable surface of the transponder label is achieved by the transponder chip arranged in the elevation and by the intermediate layer adapted to the elevation, which is arranged between the top film and the carrier. The disadvantage of this transponder label is the complex structure. Not only must the transponder chip be arranged in a specially provided elevation of the chip insert, it is also necessary to adapt the intermediate layer to this elevation. The elevation and the intermediate layer also have a thickness which prevents the transponder label from being very flat and therefore not very disruptive when the transponder label is stuck on.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Transponder-Etikett dahingehend weiterzubilden, daß es einen einfachen, möglichst flachen Aufbau geringer Dicke aufweist, bei dem insbesondere im Bereich des Chips keine hervorstehenden Bereiche ausgebildet sind.The object of the present invention is to further develop a generic transponder label in such a way that it has a simple, as flat as possible construction of small thickness, in which no protruding areas are formed, in particular in the area of the chip.
Diese Aufgabe wird bei einem Transponder-Etikett der eingangs beschriebenen Art gelöst durch die Merkmale der unabhängigen Ansprüche 1 und 4.This object is achieved in the case of a transponder label of the type described at the outset by the features of independent claims 1 and 4.
Von besonders großem Vorteil ist, daß die erfindungsgemäßen Transponder-Etiketten nur zwei Schichten aufweisen, eine Transponderfolie mit darauf angeordnetem Chip sowie im Falle einer ersten erfindungsgemäßen Ausgestaltung eine Kleberschicht beziehungsweise im Falle einer zweiten erfindungsgemäßen Ausgestaltung eine Deckschicht, die jeweils im Bereich des Chips eine Ausnehmung aufweisen, deren Dicke wenigstens derjenigen des Chips entspricht. Hierdurch können jegliche zusätz- liehe Zwischenlagen entfallen, denn in einem Falle bildet diese Zwischenlage gewissermaßen die Kleberschicht selbst, im Falle der anderen erfindungsgemäßen Ausbildung bildet die bedruckbare Deckschicht die Zwischenschicht.It is particularly advantageous that the transponder labels according to the invention have only two layers, a transponder film with a chip arranged thereon and, in the case of a first embodiment according to the invention, an adhesive layer or in the case of a second embodiment according to the invention a cover layer, each of which has a recess in the area of the chip have, whose thickness corresponds at least to that of the chip. Any additional Intermediate layers are not necessary, because in one case this intermediate layer forms the adhesive layer itself to a certain extent, in the case of the other embodiment according to the invention the printable cover layer forms the intermediate layer.
Dieser Zweischicht-Aufbau ermöglicht die Ausbildung äußerst flacher Transponder-Etiketten mit einfachem Aufbau, die aufgrund der auf den Chip angepaßten Ausnehmung in der Kleberschicht beziehungsweise Deckschicht an ihrer Oberseite keinerlei Erhebung aufweisen und damit optimal bedruckbar sind.This two-layer structure enables the formation of extremely flat transponder labels with a simple structure which, because of the recess in the adhesive layer or cover layer adapted to the chip, have no elevation on their upper side and are therefore optimally printable.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Ausnehmung kann dabei rein prinzipiell jegliche beliebige Gestalt aufweisen, insbesondere kann sie einfach durch Ausstanzen eines etwa kreisrunden Loches ausgebildet sein. Vorteilhafte Ausfuhrungsformen sehen vor, daß die Kontur der Ausnehmung an die Form des Chips angepaßt ist, so daß keinerlei Hohlräume in der Umgebung des Chips entstehen können.In principle, the recess can have any shape, in particular it can be formed simply by punching out an approximately circular hole. Advantageous embodiments provide that the contour of the recess is adapted to the shape of the chip, so that no cavities can arise in the area surrounding the chip.
Wenn wie im Falle der vorstehend erstgenannten erfindungsgemäßen Ausgestaltung der Chip gewissermaßen in die Kleberschicht eingebettet ist und mittels dieser auf einem Träger befestigt ist, kann vorgesehen sein, daß die Transponderfolie auf ihrer dem Chip abgewandten Seite mit einer bedruckbaren Deckschicht versehen ist. Sowohl bei der ersten als auch bei der zweiten erfindungsgemäßen Ausgestaltung kann die Deckschicht als eine bedruckbare Deckfolie ausgebildet sein, die insbesondere hinsichtlich des flachen Aufbaus des Transponder-Etiketts von großem Vorteil ist und darüber hinaus auch leicht handhabbar ist.If, as in the case of the above-mentioned first embodiment of the invention, the chip is embedded in the adhesive layer and attached to a carrier by means of it, it can be provided that the transponder film is provided with a printable cover layer on its side facing away from the chip. Both in the first and in the second embodiment according to the invention, the cover layer can be designed as a printable cover film, which is of great advantage in particular with regard to the flat structure of the transponder label and is also easy to handle.
Bei einem insbesondere für die Verwendung in Verbindung mit CD-Roms besonders vorteilhaften Ausführungsbeispiel sind zum Gewichtsausgleich Ausnehmungen oder Löcher in der Transponderfolie und/oder der Deckschicht und/oder der Klebefolie, etwa durch Ausstanzen, vorgesehen.In an embodiment which is particularly advantageous for use in conjunction with CD-Roms, recesses or holes are provided in the transponder film and / or the cover layer and / or the adhesive film, for example by punching, for weight compensation.
Eine weitere vorteilhafte Ausfuhrungsform sieht eine Transponderfolie aus einem opaken Material vor.Another advantageous embodiment provides a transponder film made of an opaque material.
Die Transponderfolie kann darüber hinaus vorteilhafterweise auch selbst als Deckfolie ausgebildet sein und bei Bedarf auf ihrer dem Chip abgewandten Seite bedruckt werden.The transponder film can also advantageously be designed as a cover film and can be printed on its side facing away from the chip if necessary.
Bevor die Transponder-Etiketten auf den zu kennzeichnenden Träger aufgeklebt werden, wird eine Trägerschicht, beispielsweise ein Silikonpapier abgezogen.Before the transponder labels are glued to the carrier to be labeled, a carrier layer, for example a silicone paper, is peeled off.
Die vorbeschriebenen Transponder-Etiketten sind selbst- klebende Transponder-Etiketten, die auf einen Träger, beispielsweise auf einen Gegenstand, auf eine CD-ROM oder dergleichen aufgeklebt werden können. Eine weitere Ausfuhrungsform eines nicht selbstklebenden Transponder-Etiketts sieht vor, daß der Träger selbst eine dünne Schicht, beispielsweise eine weitere bedruckbare Deckfolie oder Deckschicht darstellt.The transponder labels described above are self-adhesive transponder labels which can be stuck onto a carrier, for example onto an object, onto a CD-ROM or the like. A further embodiment of a non-self-adhesive transponder label provides that the carrier itself represents a thin layer, for example another printable cover film or cover layer.
Ein solches Transponder-Etikett kann beispielsweise auch die Form einer Kreditkarte, Chipkarte oder dergleichen aufweisen und auf diese Weise beispielsweise für Zugangsberechtigungen und dergleichen verwendet werden.Such a transponder label can, for example, also take the form of a credit card, chip card or the like and can be used in this way, for example, for access authorizations and the like.
Weitere Vorteile und Merkmale der Erfindung sind Gegenstand der nachfolgenden Beschreibung sowie der zeichnerischen Darstellung einiger Ausführungsbeispiele.Further advantages and features of the invention are the subject of the following description and the drawing of some exemplary embodiments.

Ein als Ganzes mit 10 bezeichnetes Transponder-Etikett, dargestellt in Fig.l, weist beispielsweise eine kreisrunde Gestalt auf. Auf dem Transponder-Etikett 10 sind ein Chip 40 sowie eine Antenne 22 angeordnet.4 is a sectional side view of another solubilizing use of the invention ■ transponder label. A transponder label designated as a whole as 10, shown in FIG. 1, has, for example, a circular shape. A chip 40 and an antenna 22 are arranged on the transponder label 10.
Der Schichtaufbau des Transponder-Etiketts 10 ist schematisch in Fig.2 dargestellt.The layer structure of the transponder label 10 is shown schematically in FIG.
Der Chip 40 ist auf einer Transponderfolie 30 angeordnet, wobei er gewissermaßen eingebettet ist in eine Kleberschicht 50, die beispielsweise als Klebefolie ausgebildet sein kann und eine Dicke d aufweist, die wenigstens der des Chips 40 entspricht. Im Bereich des Chips 40 weist die Kleberschicht 50 eine Ausnehmung 52 auf, deren Kontur vorteilhafterweise an die Gestalt des Chips 40 angepaßt sein kann.The chip 40 is arranged on a transponder film 30, wherein it is, so to speak, embedded in an adhesive layer 50, which can be designed, for example, as an adhesive film and has a thickness d that corresponds at least to that of the chip 40. In the area of the chip 40, the adhesive layer 50 has a recess 52, the contour of which can advantageously be adapted to the shape of the chip 40.
Die Transponderfolie 30 kann gleichzeitig als Deckfolie ausgebildet sein und bei Bedarf auf ihrer dem Chip 40 abgewandten Seite bedruckt werden.The transponder film 30 can at the same time be designed as a cover film and, if necessary, can be printed on its side facing away from the chip 40.
Bei einem weiteren Ausführungsbeispiel, dargestellt in Fig.3, sind diejenigen Elemente, die mit denen des ersten, in Fig.l und Fig.2 beschriebenen Ausführungsbei- spiel identisch sind, mit denselben Bezugszeichen versehen, so daß bezüglich deren Beschreibung auf die Ausführungen zum ersten Ausführungsbeispiel voll inhaltlich Bezug genommen wird. Dieses Ausführungsbeispiel unterscheidet sich von dem ersten dadurch, daß eine zusätzliche Deckschicht in Form einer Deckfolie 70 vorgesehen ist, die bei Bedarf bedruckbar ist. Bei einem anderen erfindungsgemäßen Transponder- Etikett, dargestellt in Fig.4, sind wiederum diejenigen Elemente, die mit denen des in Fig.l und Fig.2 dargestellten Transponder-Etiketts identisch sind, mit denselben Bezugszeichen gekennzeichnet, so daß bezüglich deren Beschreibung auf die Ausführungen zum ersten und zweiten Ausführungsbeispiel voll inhaltlich Bezug genommen wird.In a further exemplary embodiment, shown in FIG. 3, those elements which are identical to those of the first exemplary embodiment described in FIGS. 1 and 2 are provided with the same reference numerals, so that, with regard to their description, the explanations for first embodiment is fully referred to. This exemplary embodiment differs from the first in that an additional cover layer is provided in the form of a cover film 70 which can be printed on if required. In the case of another transponder label according to the invention, shown in FIG. 4, those elements which are identical to those of the transponder label shown in FIGS. 1 and 2 are again identified by the same reference numerals, so that their description refers to the Reference is made to the content of the first and second exemplary embodiments.
Im Gegensatz zu dem oben in Verbindung mit Fig.l und Fig.2 sowie dem in Verbindung mit Fig.3 beschriebenen Transponder-Etiketten ist bei dem in Fig.4 dargestellten Transponder-Etikett der Schicht-Aufbau jedoch gewissermaßen umgekehrt. Der Chip 40 ist nach außen freiliegend angeordnet, was problemlos möglich ist, da seine Anschlüsse auf seiner der Tranpsonderfolie 30 zugewandten Seite angeordnet und beispielsweise in Flip- Chip-Technik ausgeführt und kontaktiert sind. Der Chip 40 selbst ist in eine Deckschicht 70' eingebettet, deren Dicke d1 wenigstens derjenigen des Chips 40 entspricht und die bei Bedarf bedruckbar ist.In contrast to the transponder label described above in connection with FIGS. 1 and 2 and the transponder label described in connection with FIG. 3, the layer structure in the transponder label shown in FIG. 4 is reversed to a certain extent. The chip 40 is exposed to the outside, which is possible without any problems since its connections are arranged on its side facing the transponder film 30 and are designed and contacted, for example, using flip-chip technology. The chip 40 itself is embedded in a cover layer 70 ', the thickness d 1 of which corresponds at least to that of the chip 40 and which can be printed on if required.
Im Bereich des Chips 40 weist die Deckschicht 70' eine Ausnehmung 72' auf, deren Form an die Kontur des Chips 40 angepaßt oder einfach, beispielsweise durch Ausstanzen oder dergleichen, kreisrund ausgebildet sein kann.In the area of the chip 40, the cover layer 70 'has a recess 72', the shape of which can be adapted to the contour of the chip 40 or can be circular, for example by punching or the like.
Bei diesem Transponder-Etikett ist auf der dem Chip 40 zugewandten Seite der Transponderfolie 30 eine Klebeschicht 50', beispielsweise in Form einer sehr dünnen Klebefolie, wie in Fig.4 dargestellt, angeordnet, mittels der das Transponder-Etikett auf den Träger 60 aufgeklebt werden kann.In this transponder label there is an adhesive layer 50 ', for example in the form of a very thin layer, on the side of the transponder film 30 facing the chip 40 4, arranged by means of which the transponder label can be stuck onto the carrier 60.
Bevor die vorbeschriebenen Etiketten auf einen zu kennzeichnenden Träger aufgeklebt werden, muß eine Trägerschicht, beispielsweise ein Silikonpapier abgezogen werden.Before the labels described above are glued to a carrier to be labeled, a carrier layer, for example a silicone paper, must be removed.
Die vorbeschriebenen Transponder-Etiketten sind selbstklebende Etiketten. Es ist darüber hinaus aber auch möglich, diese Etiketten als nicht selbstklebende Etiketten auszubilden. In diesem Falle werden die Etiketten nicht auf einen Träger 60 aufgeklebt, sondern der Träger 60 wird durch eine Schicht 60' gebildet, die beispielsweise so ausgebildet ist, wie die Transponderfolie 30 oder - wie im Falle des in Verbindung mit Fig. 3 beschriebenen Ausführungsbeispiels - wie die Folie 70. Ein solches nicht selbstklebendes Transponder- Etikett kann beispielsweise die Gestalt einer Kreditkarte, Chipkarte oder eine andere beliebige Form aufweisen und so beispielsweise als Zugangsberechtigungs- karte verwendet werden. The transponder labels described above are self-adhesive labels. However, it is also possible to design these labels as non-self-adhesive labels. In this case, the labels are not glued onto a carrier 60, but the carrier 60 is formed by a layer 60 'which is designed, for example, like the transponder film 30 or - as in the case of the exemplary embodiment described in connection with FIG. 3 - like the film 70. Such a non-self-adhesive transponder label can, for example, take the form of a credit card, chip card or any other shape and can thus be used, for example, as an access authorization card.
