Description

The present invention relates to labels for secure marking to visibly identify or partially coded an item such as a passport or a personal card, or a transparent element, by example a glass wall such as a windshield automobile. For this last application, the information must be definitively set to inside the passenger compartment, on the glass wall, and be visible from the outside. These may be documents such as that for example registration cards, insurance receipts or tax stamps. These documents carry general information supplemented by specific information specific to the vehicle or its owner.

The general principle of such labels is described by various patents of the prior art, for example European patents EP170712, EP505689 and EP218524, the German patents DE4405946 and DE4414149 and the patent French FR2699312. Generally speaking, such labels of markings are composed of a support such as a sheet of plastic with an imprint on its first side, means of authentication difficult reproducible by counterfeiters, a hologram by example, and a layer of adhesive allowing to stick the label on the glass of a vehicle, to allow reading the inscriptions printed on the support, but making it impossible to withdraw without destroying the label.

The plaintiff has also designed a label improved constituted by a complex formed by two superimposed elements between which an element is interposed marking, at least one of said elements having a clean layer to bond on the support transparent and at least one of said elements comprising a diffracting grating. The first element is formed by a transparent plastic film on one of the faces an adhesive suitable for bonding said element to the transparent support to mark and presenting on the other face a layer of embrittlement and a layer of varnish transparent stamped with a holographic image.

The second element consists of a film transparent coated with an embrittlement layer and a layer of varnish stamped with a holographic image and by a clean adhesive to bind the element on the support transparent to mark and on the element.

These labels have a high degree of security. However, their manufacture requires resources manufacturers who are not suitable for production of small series.

The object of the present invention is to remedy this disadvantage by proposing a label for marking high security, allowing individualization without tools industrial.

To this end, the invention relates to a system of security marking for the production of a secure marking according to claim 1.

The safety marking system for the creation of a secure marking label according to the invention consists of a support sheet such than a sheet of silicone plastic, having two flaps separated by a fold line, the first flap supporting on the front side a first component holographic whose face coming into contact with the backing sheet is coated with an adhesive layer, the second flap supporting on the reverse side a second component formed by a film whose face coming into contact with the backing sheet is coated with an adhesive layer and the opposite side of which at least bears inscriptions official customization.

The two components are arranged so that they overlap when the backing sheet is folded along the fold line.

The first part presents at the level of the first composing a pre-cut tab on three sides, the dimensions of this area being smaller than the dimensions of the first component, this tab can be folded down to allow the connection between the two components.

The first component is destructible in the event of attempt to take off from the system.

Preferably, the dimensions of the first component are larger than the dimensions of the second component.

According to another alternative embodiment, the second component also has inscriptions affixed to the adhesive side.

According to another alternative embodiment, the first component has inscriptions of individualization affixed on the external face.

• la figure 2 représente une vue en coupe d'un système selon l'invention ;
• la figure 3 représente une vue de l'étiquette obtenue avec le système selon l'invention.

The invention will be better understood on reading the following description, referring to the accompanying drawings, in which:

• FIG. 1 represents a front view of a system according to the invention;
• Figure 2 shows a sectional view of a system according to the invention;
• FIG. 3 represents a view of the label obtained with the system according to the invention.

Figure 1 shows a back side view of a marking system according to the invention.

It is formed by a silicone sheet (1) constituting the support of the two components (2) and (3). This sheet has two sections (4, 5) separated by a fold line, for example a prérainé line (6). The two flaps (4, 5) have identical dimensions, higher than those of the two components (2, 3).

The first part (4) presents an area precut on three sides (7, 8 and 9) and pre-cleaned on the fourth side (10), to delimit a tab (11) folding. This tab has a dimension less than that of the first component (2) bonded to the front side, that is to say the face opposite to that shown on the figure 1.

The second part relates to its back side, that is to say that visible in Figure 1, the second component (3) formed by a transparent plastic film bearing an inscription (12) affixed in opaque ink or translucent on the transparent film, and a second zone printed (13) affixed to an opaque area. The impression (13) is made on the outer face, that is to say the opposite side to the adhesive side glued against the film support (1).

The two components (2, 3) are arranged on the support film (1) symmetrically with respect to the line (6) so that the second component (3) comes position, when the two flaps are folded one on the other, on the back of the first component (2), at the area delimited by the lines (7 to 10). Of course, before this operation, the tab (11) is folded down to release the central part of the back of the first component (2) and to allow the bonding of the second component on the first component.

Figure 2 shows a view in section AA of the marking system presented in figure 1. The thicknesses are exaggerated to make the drawing legible.

The first component (2) is a component holographic formed for example by a layer of varnish stamped metallized (13 ') covered by an adhesive (14). This component may have one or more compositions holographic, as well as optionally a zone transparent revealing inscriptions carried on the second component. The holographic component is stamped on both sides so as to show holographic images on both sides of the label which will be carried out.

The second component (3) is formed by a film transparent (15) also carrying an adhesive layer (16) and different prints (17) or (19). Some inscriptions (17) are formed by opaque inks or translucent on the transparent background. Other inscriptions (19) are covered by an opaque ink (18) forming also a layer of embrittlement. other inscriptions can be carried over manually on the back of the film before the meeting of the two components, so to individualize the marking label which will be thus performed.

Figure 3 shows a view of the label produced according to the invention. Both components have been superimposed and rolled in a known manner. The label is thus formed on the first flap (4) including the tab (11) can again be replaced to protect the adhesive surface. The label seen from the back (face of the first component (2) initially glued to the support sheet) shows diffracting zones (20, 21) and printed areas, some of which (22) appear in contrasts on an opaque background and other prints (24) appear on a transparent background revealing the holographic images of the first component.

The invention is described in the foregoing to by way of nonlimiting example. It is understood that the skilled person will be able to realize different variants without departing from the scope of the invention.

In particular, the holographic component can be formed by a transparent hologram or by a destructible, transparent or metallic hologram. The destructible holograms have a breaking layer degrading permanently during attempts to peeling off.

The second component can be opaque or transparent, or only partially opaque. A system composed of a transparent hologram and a second partially transparent component will leave visible inscriptions appearing on the support on which it is affixed, for example a passport or card Identification.
