Definitions

  • 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.
  • 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.
  • 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.
  • the invention relates to a expanded polystyrene packaging in which the marker is incorporated.
  • the marker is thus invisible from outside.
  • 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.
  • the marker is formed by a metallic wire encapsulated in a sheath of protection allowing passage to the microwave oven.
  • the packaging can thus be introduced into a microwave oven without heating the marker by microwave only causes packaging degradation.
  • 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.
  • 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.
  • the inserts are made up by a marker coated with polystyrene beads, such marker being introduced into the mold during the step packaging manufacturing.
  • 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.
  • 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.
  • the patent FR2640584 describes another form of tray for packaging a food product. This container has the general shape of a flat-bottomed bowl.
  • 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.
  • 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.
  • a marker (2) formed by a metal wire 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.
  • 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.
  • 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.
  • Figures 2 to 7 illustrate the different steps for manufacturing a package according to the invention.
  • 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.
  • 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.
  • 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).
  • the balls are introduced into the mold (17).
  • 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.
  • 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.
  • 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.
  • the packaging is then ready to be removed from the mold.
  • 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).
  • the equipment then returns to the position of start of cycle shown in figure 2.
