Abstract
This tag, interacting with an electromagnetic monitoring barrier, is intended to trigger an alarm if it is carried through the barrier without being registered by the person operating the check-out. It has an electrical tuned circuit (C, L) formed by a printed circuit which is disposed between two films and is not visible from the outside. The two films have one or more perforation lines (P). As soon as a section of the tag is detached along one or more of the perforation lines by check-out staff, the tuned circuit is electrically interrupted or its natural frequency is detuned. This prevents any feedback effect from the tuned circuit to the monitoring field when the tag is carried through the latter and therefore also no alarm is triggered. <IMAGE>

PATENTANSPRUCH
Sicherheitsetikette für Diebstahl-Überwachungsanlagen mit einem verdeckt zwischen zwei Folien angeordneten elektrischen Schwingkreis, dadurch gekennzeichnet, dass der Schwingkreis als gedruckte Schaltung ausgebildet ist und mindestens eine Perforation zum Abtrennen eines Abschnitts der Etikette vorgesehen ist. wobei die Lage der Perforation so gewählt ist, dass beim Abtrennen des Abschnitts der Schwingkreis unterbrochen oder seine Eigenfrequenz verändert wird.
Es werden seit einiger Zeit erhebliche Anstrengungen unternommen, um den überhand nehmenden Ladendiebstählen zu begegnen. Dabei werden vermehrt auch elektromagnetische Überwachungsfelder verwendet, die der Kunde beim Verlassen des Verkaufsgeschäftes durchschreiten muss.
Durch eine an den Verkaufsgegenständen angebrachte Etikette werden diese Felderbeeinflusstund festgestellt, ob die Etikette die Kasse passiert hat oder nicht. Bei einem bekannten System ist in der Etikette - für den Käufer nicht sichtbar - ein elektrischer Schwingkreis angebracht, der aus einer sehr dünnen Flachspule und einem Kondensator besteht. Die Frequenz dieses Schwingkreises ist auf die Frequenz des elektromagnetischen Überwachungsfeldes abgestimmt. Wenn ein Kunde mit der unveränderten Etikette das Überwachungsfeld passiert, wird durch Rückwirkung des abgestimmten Kreises auf dieses ein Alarm ausgelöst. Wenn der Kunde jedoch den gekauften Gegenstand mit der Etikette ordnungsgemäss an der Kasse vorlegt, dann wird vom Kassierpersonal eine metallische Folie auf die Etikette aufgeklebt.
Dadurch wird der Schwingkreis derart verstimmt, dass beim Durchschreiten des Überwachungsfeldes eine wesentliche Rückwirkung vom Schwingkreis auf dieses unterbleibt und damit auch keine Alarmauslösung erfolgt. Diese bekannte Anordnung hat den Nachteil, dass an der Kasse spezielle Mittel zum Aufbringen der Metallfolie und eine Manipulation erforderlich ist. Die Erfindung behebt diesen Nachteil, indem die Veränderung der elektrischen Eigenschaften des aus einer gedruckten Schaltung bestehenden Schwingkreises durch das Kassierpersonal dadurch erfolgt, dass ein Abschnitt der Etikette entlang einer Perforationslinie abgetrennt wird. Anhand der Zeichnung werden nachfolgend Ausführungsbeispiele der erfindungsgemässen Etikette beschrieben.
Fig. 1 und 2 zeigen in zwei Ausführungsvarianten die auf einer undurchsichtigen Grundfolie aufgebrachte gedruckte Schaltung mit der Spule L und dem Kondensator C. Die Grundfolie kann aus Papier, Kunststoff oder aus einem feinen Gewebe bestehen. Eine ebenfalls undurchsichtige Deckfolie, welche wie in Fig. 2 dargestellt mit den, den Verkaufsgegenstand kennzeichnenden Angaben bedruckt ist, ist auf die Grundfolie aufgeklebt. Die Etikette ist mit einer Perforation P versehen, welche so angeordnet ist, dass beim Abtrennen eines Streifens oder Eckstücks durch das Verkaufspersonal der Schwingkreis unterbrochen (Fig. 1) oder seine Eigenfrequenz verändert wird (Fig. 3). Vorzugsweise wird der abgetrennte und an der Kasse zurückbleibende Abschnitt alle für das Geschäft zu Kontrollzwecken erforderlichen Informationen in Form eines aufgedruckten und maschinenlesbaren Codes enthalten.
Die Perforationen der Etikette können natürlich auch kaschiert sein, so dass sie vom Käufer nicht gesehen werden können.

PATENT CLAIM
Security label for anti-theft surveillance systems with an electrical resonant circuit hidden between two foils, characterized in that the resonant circuit is designed as a printed circuit and at least one perforation is provided for severing a section of the label. the position of the perforation being selected such that the resonant circuit is interrupted or its natural frequency is changed when the section is separated.
For some time now, considerable efforts have been made to counter the increasing shoplifting. Electromagnetic surveillance fields are increasingly being used, which the customer has to go through when leaving the shop.
A label affixed to the sales items influences these fields and determines whether the label has passed the checkout or not. In a known system, an electrical resonant circuit is attached to the label - not visible to the buyer - which consists of a very thin flat coil and a capacitor. The frequency of this resonant circuit is matched to the frequency of the electromagnetic monitoring field. If a customer passes the surveillance field with the unchanged label, an alarm is triggered by the feedback of the coordinated circle. However, if the customer properly presents the purchased item with the label at the checkout, the checkout staff will stick a metallic foil on the label.
As a result, the resonant circuit is detuned in such a way that when the monitoring field is passed through, the resonant circuit has no significant reaction to it, and therefore no alarm is triggered. This known arrangement has the disadvantage that special means for applying the metal foil and manipulation are required at the checkout. The invention eliminates this disadvantage by the cashier staff changing the electrical properties of the resonant circuit consisting of a printed circuit by severing a portion of the label along a perforation line. Exemplary embodiments of the label according to the invention are described below with the aid of the drawing.
1 and 2 show in two design variants the printed circuit with the coil L and the capacitor C applied to an opaque base film. The base film may consist of paper, plastic or a fine fabric. A likewise opaque cover film, which, as shown in FIG. 2, is printed with the information characterizing the object of sale, is glued to the base film. The label is provided with a perforation P, which is arranged such that when a strip or corner piece is cut off by the sales staff, the resonant circuit is interrupted (FIG. 1) or its natural frequency is changed (FIG. 3). Preferably, the section which is separated and left at the checkout will contain all the information required for the business for control purposes in the form of a printed and machine-readable code.
The perforations on the label can of course also be laminated so that they cannot be seen by the buyer.
