Ainsi, l'arrachement de ladite étiquette ne peut être fait sans causer la dégradation du produit lui- même .This type of information carrier has a main disadvantage in that it is very easy to tear it from the article since the information carrier, serving not only to identify in particular for the payment of the article in cash but also as a detection means during its passage between the exit gates of a store, is located outside the article to be protected. The present invention intends to remedy the drawbacks of the prior art by proposing a three-dimensional miniature label which can be produced using planar manufacturing methods used in particular for producing plates serving in a capacitor. To avoid the tearing of protections against theft and counterfeits, the present invention seeks to develop a system in which the information medium and means of detection against theft in the article itself.

Comme cela est visible sur la figure 1, l'antenne 1 selon l'invention comprend une bande métallique 2, par exemple en aluminium, posée et fixée sur un substrat isolant 3 en matière plastique par exemple, du polyteréphtalate (PET) . Bien entendu, on pourra envisager tous autres types de plastiques ou d'isolant adapté pour venir s'y fixer un matériau conducteur 2 apte à être déformé pour former une spirale ou des cylindres de diamètres concentriques .As can be seen in FIG. 1, the antenna 1 according to the invention comprises a metal strip 2, for example of aluminum, placed and fixed on an insulating substrate 3 of plastic material for example, polyterephthalate (PET). Of course, we can consider all other types of plastics or insulating material suitable for attaching a conductive material 2 capable of being deformed to form a spiral or cylinders of concentric diameters.
L'antenne 1 se présente sous une forme d'un U inversé aplati possédant, à ses deux extrémités parallèles, respectivement deux ailes 4, 4' de manière à faciliter la connexion d'une puce électronique 5 aux deux ailes 4, 4', formant pôles, de l'antenne 1.The antenna 1 is in the form of a flattened inverted U having, at its two parallel ends, respectively two wings 4, 4 'so as to facilitate the connection of an electronic chip 5 to the two wings 4, 4', forming poles, of the antenna 1.
Comme illustré sur la figure 2, l'antenne 1 selon l'invention est enroulée sur elle-même pour former un enroulement de cylindres concentriques et donc une bobine dont les deux ailes 4, 4' de l'antenne 1 en forme de U se touchent ou sont disposées l'une à proximité de l'autre, de sorte que ces deux ailes 4, 4' puissent être reliées entre elles par un pont ou en l'occurrence une puce 5.As illustrated in FIG. 2, the antenna 1 according to the invention is wound on itself to form a winding of concentric cylinders and therefore a coil whose two wings 4, 4 'of the U-shaped antenna 1 touch or are arranged one near the other, so that these two wings 4, 4' can be connected together by a bridge or in this case a chip 5.
Comme illustré sur la figure 3, une puce 5 d'une taille voisine de celle des deux ailes 4, 4' de l'antenne 1 est collée, ou fixée par tous autres moyens adéquates et bien connus de l'homme du métier, sur celles-ci 4, 4'.As illustrated in FIG. 3, a chip 5 of a size close to that of the two wings 4, 4 ′ of the antenna 1 is glued, or fixed by any other suitable means well known to those skilled in the art, on these 4, 4 '.

Plus précisément, le boîtier 6 possède un trou 8 en son centre dont les bords ont la même hauteur que le boîtier 6 lui-même. Ce trou 8 est prévu pour pouvoir insérer le boîtier 6, et éventuellement le fixer, autour d'une partie cylindrique d'un article et dont le diamètre est sensiblement équivalent au diamètre du trou 8 du boîtier 6.In the example chosen to illustrate the invention, the label 7 is placed in a casing 6 or locker of cylindrical shape and having approximately the shape and dimensions of the label 7, once the antenna 1 folded over it- even. More specifically, the housing 6 has a hole 8 in its center, the edges of which have the same height as the housing 6 itself. This hole 8 is provided in order to be able to insert the box 6, and optionally fix it, around a cylindrical part of an article and whose diameter is substantially equivalent to the diameter of the hole 8 in the box 6.
Selon l'invention, illustré sur la figure 4, l'étiquette 7 positionnée dans le boîtier 6, est fermée hermétiquement avec une matière plastique 9, par exemple du silicone que l'on verse dessus. Ainsi, immergée dans le liquide, l'étiquette 7 devient inaccessible après l'opération d'embouteillage.According to the invention, illustrated in Figure 4, the label 7 positioned in the housing 6, is sealed with a plastic material 9, for example silicone which is poured over it. Thus, immersed in the liquid, the label 7 becomes inaccessible after the bottling operation.
Comme cela est visible sur la figure 5, l'antenne 1 selon l'invention comprend une bande métallique 2, par exemple en aluminium, posée et/ou fixée sur un substrat isolant 3 en matière plastique, par exemple du polyteréphtalate (PET). L'antenne 1 présente ici un substrat 3 de forme rectangulaire et plate supportant ladite bande métallique 2 en forme de U aplatie possédant les deux extrémités, ou ailes 4, 4', parallèles et de dimensions identiques. La différence principale avec le mode de réalisation illustré sur les figures 1 à 4 réside dans le fait que le substrat isolant 3 est présent sous forme d'un rectangle et n'épouse pas, comme dans la susdite première variante, sensiblement les dimensions et la forme du conducteur métallique 2.As can be seen in FIG. 5, the antenna 1 according to the invention comprises a metal strip 2, for example of aluminum, placed and / or fixed on an insulating substrate 3 of plastic material, for example polyterephthalate (PET). The antenna 1 here has a substrate 3 of rectangular and flat shape supporting said metal strip 2 in the shape of a flattened U having the two ends, or wings 4, 4 ′, parallel and of identical dimensions. The main difference with the embodiment illustrated in FIGS. 1 to 4 lies in the fact that the insulating substrate 3 is present in the form of a rectangle and does not conform, as in the above first variant, to substantially the dimensions and the shape of the metallic conductor 2.
Les opérations ultérieures pratiquées sur l'antenne pour former une étiquette selon l'invention sont identiques à celles décrites dans le cadre de la première variante.The subsequent operations performed on the antenna to form a label according to the invention are identical to those described in the context of the first variant.
La présente invention s'applique en particulier mais non exclusivement à la protection des flacons de parfum de valeur, non représenté sur les figures. Dans ce cas, l'étiquette sans contact 7 de type RF-ID sera idéalement placée en bout de la pompe sertie sur le col du flacon.The present invention applies in particular but not exclusively to the protection of valuable perfume bottles, not shown in the figures. In this case, the contactless label 7 of RF-ID type will ideally be placed at the end of the pump set on the neck of the bottle.
On mesure alors l'avantage que représente l'étiquette 7 selon l'invention. En effet, du fait des diamètres des pompes compris entre 7 et 9 millimètres, il est difficile de réaliser de manière classique une antenne de l'étiquette sans contact, c'est-à-dire par gravure d'un circuit imprimé ou par la réalisation d'un bobinage. Par ailleurs, dans certains domaines particuliers, comme celui des parfums de luxe, il est particulièrement important que l'étiquette sans contact soit la plus discrète possible pour ne pas nuire à l'esthétique du flacon de parfum.The advantage represented by the label 7 according to the invention is then measured. Indeed, due to the diameters of the pumps between 7 and 9 millimeters, it is difficult to conventionally produce an antenna of the contactless label, that is to say by etching a printed circuit or by winding. In addition, in certain specific fields, such as that of luxury perfumes, it is particularly important that the contactless label be as discreet as possible so as not to harm the aesthetics of the perfume bottle.
L'étiquette sans contact 7 de l'invention présentera un diamètre, soit le plus grand diamètre des cylindres ou cercles formés par l'enroulement de l'antenne 1, compris entre 4 et 9 millimètres afin de s'adapter au diamètre de la partie cylindrique.The contactless label 7 of the invention will have a diameter, ie the largest diameter of the cylinders or circles formed by the winding of the antenna 1, inclusive between 4 and 9 millimeters in order to adapt to the diameter of the cylindrical part.
Ainsi, le procédé de réalisation de l'étiquette sans contact de l'invention utilise donc une technique novatrice dans le domaine des étiquettes sans contact. Ainsi, l'antenne 1 de l'étiquette sans contact 7 est réalisée, après gravure et découpe, par enroulement d'un film plastique 3 sur lequel est collé une bande conductrice 2 tels que de l'aluminium, produit couramment utilisé pour la réalisation d'étiquettes planaires de type RF-ID. L'aluminium constitue, après enroulement, les spires de l'antenne 1 et le support plastique 3 constitue les inter spires. En jouant sur, ou en modifiant, les épaisseurs de l'aluminium 2 et/ou du support 3, tous deux de quelques 1/10 de millimètres ainsi que sur la largeur de l'aluminium 2, également de quelques millimètres, et le nombre de spires de l'antenne 1, on accorde facilement l'antenne 1 ainsi réalisée avec le condensateur de la puce 5 à une fréquence particulière, par exemple de 13,56 MHz. Bien entendu, l'enroulement de l'antenne pourra également être réalisé pour n'importe quelle autre fréquence, tels que par exemple une antenne UHF ou de 2,45 GHz.Thus, the method for producing the contactless label of the invention therefore uses an innovative technique in the field of contactless labels. Thus, the antenna 1 of the contactless label 7 is produced, after etching and cutting, by winding a plastic film 3 on which a conductive strip 2 is bonded such as aluminum, a product commonly used for making RF-ID type planar labels. The aluminum constitutes, after winding, the turns of the antenna 1 and the plastic support 3 constitutes the inter turns. By varying, or modifying, the thicknesses of the aluminum 2 and / or the support 3, both by a few 1/10 of a millimeter as well as over the width of the aluminum 2, also by a few millimeters, and the number of turns of the antenna 1, the antenna 1 thus produced is easily tuned with the capacitor of the chip 5 at a particular frequency, for example 13.56 MHz. Of course, the winding of the antenna can also be carried out for any other frequency, such as for example a UHF or 2.45 GHz antenna.
Comme on l'a vu précédemment, l'antenne 1 connectée à la puce 5 est alors placée dans un boîtier 6 plastique discret, par exemple de couleur blanche ou transparente, puis rempli de résine 9 de même couleur en l'occurrence résistante à l'agressivité du parfum. Bien entendu, ce matériau de remplissage 9 sera choisi en fonction d'une part du contenu du flacon, de la bouteille ou analogue mais également en fonction de son insensibilité chimique avec le métal conducteur 2 et/ou le film plastique 3 sur lequel est fixé le métal conducteur 2. Par souci d'esthétique, le diamètre extérieur du boîtier 6 est sensiblement identique à celui de la pompe sur lequel il est placé.As we have seen previously, the antenna 1 connected to the chip 5 is then placed in a discrete plastic case 6, for example of white or transparent color, then filled with resin 9 of the same color, in this case resistant to aggressiveness of the fragrance. Of course, this filling material 9 will be chosen as a function of the content of the bottle, the bottle or the like, but also as a function of its chemical insensitivity to the conductive metal 2 and / or the plastic film 3 on which is fixed. the conductive metal 2. For aesthetic reasons, the outer diameter of the housing 6 is substantially identical to that of the pump on which it is placed.
L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet. The invention is described in the foregoing by way of example. It is understood that a person skilled in the art is able to carry out different variants of the invention without going beyond the scope of the patent.
