Abstract

A package incorporating an electromagnetic marker which can be identified by a detector has the marker in the form of a metal wire (2) between 30 and 100 mm long and 25 microns to 2 mm thick, embedded in the expanded polystyrene wall of the package (1). The wire marker can be enclosed in a protective sleeve which allows the contents of the package to be heated in a microwave oven. Preferably the marker is positioned in a mould before injecting the material which forms the package, using a support which is withdrawn during the moulding process. The support can be, e.g., in the form of hollow needles which are withdrawn from the mould core once the marker is held by the moulded material.

Description

La présente invention concerne un emballage antivol du type incorporant un marqueur électromagnétique. Ce marqueur est classiquement formé par un fil métallique propre à interagir avec un dispositif de détection.The present invention relates to packaging lock of the type incorporating a marker electromagnetic. This marker is conventionally formed by a clean metal wire to interact with a detection device.

De tels marqueurs sont connus dans l'état de la technique, et sont par exemple décrits dans les brevets français FR763681 ou plus récemment dans des brevets de perfectionnement FR2623003 ou FR2619929. Ils sont généralement apposés sur les articles à protéger sous forme d'étiquettes, comme cela est décrit dans le brevet FR2666433. Ces étiquettes présentent l'inconvénient d'être facilement neutralisées par arrachement. Le problème est particulièrement important lorsque l'étiquette est destinée à être apposée sur un support en matière plastique permettant un décollement facile, ou sur un film de protection d'un article.Such markers are known in the state of the technique, and are for example described in the French patents FR763681 or more recently in development patents FR2623003 or FR2619929. They are generally affixed to the articles to be protected in the form of labels, as described in the patent FR2666433. These labels show the disadvantage of being easily neutralized by tearing. The problem is particularly important when the label is intended to be affixed to a plastic support for detachment easy, or on an article protection film.

On connaít également par le brevet européen EP704828 un emballage présentant une cavité dans laquelle est logé un marqueur magnétostrictif. Un tel emballage ne présente toutefois pas un niveau de sécurité satisfaisant, car la position du marqueur est aisément repérée, et le marqueur peut donc facilement être neutralisé ou retiré.We also know by the European patent EP704828 a package having a cavity in which is housed a magnetostrictive marker. Such packaging does not have a level of satisfactory security, because the position of the marker is easily located, so the marker can easily be neutralized or removed.

Le but de l'invention est de proposer un emballage sécurisé présentant un degré de sécurité plus élevé, et étant de plus compatible avec le conditionnement de produits alimentaires tels que de la viande, des légumes, ou encore tous produits habituellement conditionnés dans de tels emballages.The object of the invention is to propose a secure packaging with a higher level of security high, and being more compatible with the packaging of food products such as meat, vegetables, or any other product usually packaged in such packages.

A cet effet, l'invention concerne un emballage en polystyrène expansé dans lequel le marqueur est incorporé. Le marqueur est ainsi invisible de l'extérieur. To this end, the invention relates to a expanded polystyrene packaging in which the marker is incorporated. The marker is thus invisible from outside.

Préférentiellement, le marqueur est formé par un tronçon d'une longueur comprise entre 30 et 100 millimètres, et d'une section de l'ordre de 25 microns à 2 millimètres.Preferably, the marker is formed by a section with a length between 30 and 100 millimeters, and of a section on the order of 25 microns at 2 millimeters.

Selon une variante avantageuse, le marqueur est formé par un fil métallique encapsulé dans une gaine de protection permettant le passage au four micro-onde.According to an advantageous variant, the marker is formed by a metallic wire encapsulated in a sheath of protection allowing passage to the microwave oven.

L'emballage peut ainsi être introduit dans un four à micro-ondes sans que l'échauffement du marqueur par les hyperfréquences ne provoque de dégradation de l'emballage.The packaging can thus be introduced into a microwave oven without heating the marker by microwave only causes packaging degradation.

L'invention concerne également un procédé de fabrication d'un emballage antivol caractérisé en ce que l'on positionne un marqueur électromagnétique dans un moule préalablement à l'injection du matériau constituant l'emballage.The invention also relates to a method of manufacture of anti-theft packaging characterized in that we place an electromagnetic marker in a mold prior to material injection constituting the packaging.

Selon un mode de mise en oeuvre préféré, on positionne un marqueur dans le moule à l'aide d'un support et on retire ledit support en cours de moulage.According to a preferred embodiment, place a marker in the mold using a support and the said support is removed during molding.

Avantageusement, on positionne le marqueur à l'intérieur du moule à l'aide d'une aiguille creuse laissant dépasser l'extrémité distale du marqueur, et en ce que l'on retire ladite aiguille creuse lorsque l'extrémité du marqueur est retenue par le matériau en cours de moulage.Advantageously, the marker is positioned at the inside of the mold using a hollow needle leaving beyond the distal end of the marker, and what we withdraw said hollow needle when the end of the marker is retained by the material molding courses.

Selon un autre mode de réalisation, on prépare des inserts formés par des marqueurs revêtus par un matériau constitutif de l'emballage et en ce que l'on introduise un tel insert dans le moule de fabrication de l'emballage.According to another embodiment, we prepares inserts formed by markers coated with a constituent material of the packaging and in that one introduce such an insert into the mold for manufacturing packaging.

Avantageusement, les inserts sont constitués par un marqueur enrobé de billes de polystyrène, un tel marqueur étant introduit dans le moule pendant l'étape de fabrication de l'emballage.Advantageously, the inserts are made up by a marker coated with polystyrene beads, such marker being introduced into the mold during the step packaging manufacturing.

L'invention sera mieux comprise à la lecture de la description qui suit, faisant référence aux figures annexées relatives à des exemples non limitatifs de réalisation où :

  • la figure 1 représente une vue en perspective d'un emballage antivol selon l'invention ;
  • les figures 2 à 7 représentent des vues schématiques des différentes étapes de fabrication d'un tel emballage.
The invention will be better understood on reading the description which follows, referring to the appended figures relating to nonlimiting exemplary embodiments where:
  • FIG. 1 represents a perspective view of an anti-theft packaging according to the invention;
  • Figures 2 to 7 show schematic views of the different stages of manufacturing such packaging.

La figure 1 représente une vue en perspective d'un emballage antivol selon l'invention. Il est constitué par une barquette (1) en polystyrène expansé dont la forme et les caractéristiques extérieures sont connues dans l'état de la technique. De telles barquettes sont habituellement employées pour le conditionnement de produits tels que de la viande, des légumes, ou encore tous produits habituellement conditionnés dans de tels emballages. Elles sont généralement fermées avec un film transparent. De telles barquettes sont décrites par exemple dans le brevet FR2648792. Ce brevet concerne une barquette alimentaire à base de polystyrène destinée à l'emballage sous vide de produit frais par drapage d'un film plastique souple comportant une languette d'ouverture et son procédé de fabrication. Un autre brevet de l'art antérieur, le brevet FR2640584 décrit une autre forme de barquette pour le conditionnement d'un produit alimentaire. Cette barquette a la forme générale d'une cuvette à fond plat. Elle est destinée à recevoir le produit et à être recouverte ensuite d'un film mince en matière plastique. Le fond plat est garni d'une série de fines nervures agencées pour supporter le produit à une certaine distance au-dessus du fond, de telle façon que le produit n'entre pas en contact avec les plages de ce fond qui se trouvent entre les nervures. L'air emprisonné sous le film mince peut circuler librement dans l'espace forme entre le produit et le fond. Figure 1 shows a view in perspective of anti-theft packaging according to the invention. he consists of a polystyrene tray (1) expanded whose shape and characteristics external are known in the state of the art. Of such trays are usually used for packaging of products such as meat, vegetables, or all the usual products packed in such packages. They are usually closed with a transparent film. Such trays are described for example in the patent FR2648792. This patent concerns a food tray polystyrene-based for vacuum packaging fresh product by draping a flexible plastic film comprising an opening tab and its method of manufacturing. Another prior art patent, the patent FR2640584 describes another form of tray for packaging a food product. This container has the general shape of a flat-bottomed bowl. It is intended to receive the product and to be then covered with a thin plastic film. The flat bottom is lined with a series of fine ribs arranged to support the product at a certain distance above the bottom, so that the product does not come into contact with the ranges of this between the ribs. The air trapped under the thin film can flow freely in the space between the product and the bottom.

L'emballage se différencie de ces barquettes de l'art antérieur par le fait que l'une des parois incorpore un marqueur (2) formé par un fil métallique. A titre d'indication, il s'agit d'un fil magnétique, par exemple en un alliage de cobalt, ou un métal présentant une caractéristique d'hystérésis magnétique spécifique permettant une caractérisation facile avec un système de détection comprenant une boucle d'induction.The packaging differs from these trays of the prior art by the fact that one of the walls incorporates a marker (2) formed by a metal wire. AT as an indication, it is a magnetic wire, by example of a cobalt alloy, or a metal having a characteristic of magnetic hysteresis specific allowing easy characterization with a system of detection including an induction loop.

Ce fil présente une longueur de l'ordre de 70 millimètres et une section de 25 microns. Il est intégralement noyé dans le matériau formant la paroi de l'emballage. L'emballage ne présente aucun orifice d'introduction de ce marqueur (2), de façon à empêcher le repérage visuel de son positionnement.This wire has a length of the order of 70 millimeters and a section of 25 microns. It is completely embedded in the material forming the wall of packaging. The packaging has no holes introduction of this marker (2), so as to prevent visual identification of its positioning.

La figure 2 représente un exemple d'équipement pour la fabrication d'un tel emballage. L'emballage est fabriqué de façon connue à l'aide d'un moule (17) dans lequel sont injectés les billes de polystyrène, expansées de façon habituelle par de la vapeur. L'une des parois (18) du moule (17) présente un orifice permettant le passage d'un support de marqueurs. Ce support est constitué de deux tronçons cylindriques (14, 15) concentriques. Le tronçon intérieur (15) reçoit des marqueurs (10, 11, 12) grâce à un système d'alimentation.Figure 2 shows an example of equipment for the manufacture of such packaging. The packaging is produced in a known manner using a mold (17) into which the balls of polystyrene, usually expanded with steam. One of the walls (18) of the mold (17) has a orifice allowing the passage of a support for markers. This support consists of two cylindrical sections (14, 15) concentric. The interior section (15) receives markers (10, 11, 12) thanks to a system feed.

Les figures 2 à 7 illustrent les différentes étapes de fabrication d'un emballage selon l'invention.Figures 2 to 7 illustrate the different steps for manufacturing a package according to the invention.

Le marqueur est préparé sous forme de bobine découpés en tronçons (10, 11, 12) d'une longueur Lm de 70 millimètres dans l'exemple décrit.The marker is prepared in the form of a reel cut into sections (10, 11, 12) with a length Lm of 70 millimeters in the example described.

Le support de marqueur est formé de deux aiguilles creuses (14, 15) concentriques. L'aiguille extérieure (14) présente une longueur Lae d'une longueur égale à Lm+P, où P désigne la distance entre l'extrémité (16) du marqueur (10) et la paroi (18) du moule, dans l'emballage définitif. P désigne la profondeur du marqueur.The marker holder is formed by two concentric hollow needles (14, 15). The outer needle (14) has a length Lae of a length equal to L m + P, where P denotes the distance between the end (16) of the marker (10) and the wall (18) of the mold, in l 'final packaging. P denotes the depth of the marker.

L'aiguille intérieure (15) présente une longueur Lai égale à plusieurs tronçons de marqueurs (10 à 12), soit dans l'exemple décrit 210 millimètres. La section de l'aiguille intérieur (15) est déterminée de façon à permettre un avancement des marqueurs sans friction. La figure 3 représente une vue de face avant de l'ensemble formé par les deux aiguilles concentriques et du marqueur (10). La section des marqueurs (10, 11, 12) est inférieure à la section de l'aiguille intérieure (15), mais suffisante pour empècher le chevauchement de deux marqueurs à l'intérieure du canal médulaire de l'aiguille intérieure (15).The inner needle (15) has a length L ai equal to several sections of markers (10 to 12), ie in the example described 210 millimeters. The section of the inner needle (15) is determined so as to allow advancement of the markers without friction. FIG. 3 represents a front view of the assembly formed by the two concentric needles and of the marker (10). The section of the markers (10, 11, 12) is smaller than the section of the inner needle (15), but sufficient to prevent the overlapping of two markers inside the medular channel of the inner needle (15).

Au début du cycle de fabrication d'un nouvel emballage, les billes sont introduites dans le moule (17).At the start of the manufacturing cycle for a new packaging, the balls are introduced into the mold (17).

L'aiguille intérieure (15) et l'aiguille extérieure (14) sont toutes deux en position avancée, et pénètre à l'intérieure du moule d'une longueur d'environ 90 mm.The inner needle (15) and the needle outer (14) are both in the advanced position, and penetrates inside the mold with a length of about 90 mm.

L'extrémité avant (19) du marqueur (10) le plus avancé dépasse des aiguilles d'une longueur d'environ 5 mm. L'aiguille intérieure (14) est alors retirée, jusqu'à occuper une position dans laquelle sont extrémité avant se situe dans le plan de l'extrémité avant du deuxième marqueur (11), comme représenté en figure 4.The front end (19) of the marker (10) the more advanced protruding needles one length about 5 mm. The inner needle (14) is then withdrawn, until occupying a position in which are front end is in the plane of the end before the second marker (11), as shown in figure 4.

Le marqueur (10) repose dans le canal médulaire de l'aiguille extérieure (14) et est bloquée à l'arrière par l'aiguille intérieure (15). La figure 4' représente une vue de face avant des deux marqueurs consécutifs (10, 11) au moment de la cuisson des billes de polystyrène. Le marqueur (10) est bloqué à l'extrémité avant (19) par les billes de polystyrène qui commencent leur expansion. The marker (10) rests in the channel medular of the outer needle (14) and is blocked at the rear by the inner needle (15). Figure 4 ' represents a front view of the two markers consecutive (10, 11) at the time of cooking the balls of polystyrene. The marker (10) is blocked at the front end (19) by the polystyrene balls which begin their expansion.

On retire ensuite, comme indiqué en figure 5, l'aiguille extérieure (14), puis l'aiguille intérieure (15) qui servait de butée. L'expansion des billes se poursuit, ce qui obture le canal laissé par le retrait des aiguilles (14, 15).Then remove, as shown in figure 5, the outer needle (14), then the needle interior (15) which served as a stop. The expansion of beads continues, which closes the channel left by the removal of needles (14, 15).

L'emballage est alors prêt à être démoulé.The packaging is then ready to be removed from the mold.

L'étape suivante représentée en figure 6 consiste à procéder à l'avancement des aiguilles (14, 15) et des marqueurs d'une longueur de 70 mm à l'aide d'un ensemble de machoires (26). On découpe un tronçon (20) supplémentaire, à l'aide d'un outil tranchant (25).The next step shown in Figure 6 consists in advancing the needles (14, 15) and markers with a length of 70 mm using a set of jaws (26). We cut a section (20) additional, using a cutting tool (25).

Pour revenir en début de cycle, on continue l'introduction des aiguilles (14, 15) dans le moule et on fait progresser les tronçons (11, 12, 20) à l'aide de la mâchoire (26) jusqu'à ce que le nouveau tronçon avant (11) déborde de 5 millimètres de l'extrémité avant de l'aiguille creuse intérieure (15).To return to the beginning of the cycle, we continue the introduction of the needles (14, 15) into the mold and the sections (11, 12, 20) are advanced using the jaw (26) until the new front section (11) protrudes 5 millimeters from the front end of the inner hollow needle (15).

L'équipement retrouve alors la position de début de cycle représentée en figure 2.The equipment then returns to the position of start of cycle shown in figure 2.

L'invention est décrite dans ce qui précède à titre d'exemple non limitatif. Il est entendu que l'Homme du métier sera à même de réaliser diverses variantes sans pour autant sortir du cadre de l'invention.The invention is described in the foregoing by way of nonlimiting example.
