Definitions

  • the present invention relates to a method of protecting objects against theft intended in particular, but not exclusively, for large surfaces distributing self-service products and the products obtained by this method.
  • object we mean any material article and by packaging, any envelope which covers or attaches the article.
  • an alarm signal is triggered.
  • a label carrying a circuit tuned to the frequency of the wave emitted by the transmitter passes through the barrier, a certain amount of current is induced in the resonant circuit, and it follows that the receiver notices a reception level drops and triggers an alarm signal by means of a toggle.
  • the label including the resonant circuit can also be deactivated, either by sticking on the circuit a patch including at least one layer of metal, which shifts the resonant circuit in frequency and prevents the action of the field of the monitoring device. and consequently the triggering of the alarm when the client crosses the barrier.
  • US-A-4,075,618 has already proposed to hide anti-theft labels sensitive to electromagnetic radiation or to a magnetic field, out of the sight of the purchaser.
  • the proposed circuits are ill-suited to the desired goal.
  • the present invention aims to overcome the drawback resulting from the separation of the label and the product inside the store and aims to generalize the electronic protection of articles or objects offered for sale in self-service.
  • the method of protecting objects against theft using a label carrying a flat resonant circuit used inside a gantry emitting an electromagnetic radio frequency wave using a flat resonant circuit composed of a coil and a capacity is characterized in that it consists in integrating at least one resonant circuit in the object itself and / or in its tamper-proof packaging, during manufacture, so that the circuit rendered invisible cannot be removed without destroying the object.
  • the circuit is directly integrated into the object and cannot be removed from it without the object being broken.
  • the protection circuit is not only invisible which provides initial protection, but it is inaccessible, which prevents any neutralization maneuver.
  • the integration of the circuit into the product is preferably carried out during the manufacture of the latter, during molding or thermoforming or by insertion between two layers in the case of laminated products.
  • a protection circuit is included in the product itself, a second circuit in its housing, and a third circuit in its packaging shell.
  • the bare object itself may have only a reduced value compared to the resale price when the packaging is intact. It is therefore desirable to also protect the packaging and shells, although the intrinsic value of these is negligible.
  • the present invention relates in particular to the protection of products with high added value such as video cassettes, compact discs with laser reading, and audio cassettes. But of course, the invention can be implemented for all other objects such as "black" discs, shoes, books, hats.
  • the safety circuit included in the object or in its packaging is a deactivable circuit, that is to say that it can be interrupted after a first passage in an electromagnetic field of appropriate frequency and power.
  • This deactivation can be obtained, for example, by providing a fuse-resistant part forming a safety lead on the circuit, but the circuit may very well remain in the state, since it is no longer called to pass through another gantry later. control.
  • the video cassette consists of two reels 1 and 2 on which the magnetic tape mounted inside a cassette 3 is wound.
  • the protection can be arranged during the injection of the cassette 3 in any place on a wall thereof.
  • the circuit C1 was introduced into the front front part of the cassette before the latter is loaded with the magnetic tape. It is also possible to introduce a circuit C2 on the flange of one of the coils 1 or 2, after manufacture of the cassette 3. In certain cases, it is also possible to integrate a circuit at the end of the strip, provided that there is no disturbance at the level of the read heads. The video cassette itself is thus protected, regardless of its packaging.
  • cassettes are housed, for distribution, in boxes such as the box 4 shown in Figure 2 which is advantageously made by thermoforming.
  • a circuit C3 is introduced into the same wall of the housing 4 during thermoforming.
  • the casing 4 of the cassette is itself generally introduced, for self-service distribution, in a transparent thermoformed plastic shell 5 having hooking means 6 and a labeling zone 7, as shown in Figure 3.
  • the security circuit is included at this time between the two folded parts of the label 7 for information or advertising, so that it is in no way apparent.
  • the circuit C4 can be non-deactivable.
  • the safety circuit used is presented, for reasons of convenience, in a rectangular shape whose dimensions are, for example, the following: 10 ⁇ 2 cm or 4 ⁇ 15 cm.
  • the circuits used until now were generally square in shape, which facilitated the production of flat coils, but presented problems of space when it came to integrating these labels into the product.
  • FIG. 4 shows in perspective a compact disc 8 inside its housing generally designated by 9.
  • the safety circuit is in this case, advantageously, arranged like the circuit C8 along the hinge.
  • a compact disc case comprises an opaque base portion 10, on which a transparent cover 11 can be folded down generally containing an information booklet.
  • the particular problem which arises in the case of compact discs stems from the fact that they comprise a metallized surface which disturbs or inhibits the reception of radio frequency radiation so that, if the security label is placed on or under the protection becomes ineffective. It is therefore essential to have the safety circuits outside the area constituting the grip of the disc 8 and, as shown in C7 in FIG. 4, inside the opaque bottom 10.
  • FIG. 5 represents a conventional cassette 12, FIG. 6 an injected housing 18 allowing the protection of the cassette 12, this housing 13 usually being produced by injection of plastics.
  • An audio cassette case 13 generally comprises an opaque base on which a transparent cover, for example made of crystal polystyrene, is articulated.
  • a transparent cover for example made of crystal polystyrene
