• the security envelope according to the invention comprises a sleeve 1 of heat-shrinkable plastic material cut in a sheath made with a film in said material.
• the sleeve 1 is equipped on its outer face with a safety strip 2 of delaminable multilayer material which extends substantially along a generatrix of the sleeve so that when the sleeve is placed on the neck of a container, the strip extends substantially vertically.
• the sleeve is for example made in a monolayer polyester film (such as PET) stretched to give it a preferred direction of retraction.
• the sleeve is made of a multilayer heat shrinkable material. Said heat-shrinkable multilayer material consists for example of various delaminable layers.
• the security strip 2 is cut from a flat material made up of various delaminable layers, including an adhesive layer enabling it to be bonded against the sleeve 1.
• a multilayer material will be used which comprises an adhesive layer, a polypropylene layer, and an outer layer here constituted of a secure coating that can receive security signs.
• the outer layer may for example be paper, plastic or have embossed inscriptions.
• the multilayer material of the secure strip is not heat-shrinkable. In this way it is easier to write security signs on the security band.
• the portion of the sleeve covered by the safety band will be less subject to retraction than the rest of the sleeve, which will also facilitate the possible inscription of security signs on this part of the sleeve.
• the sleeve 1 comprises cutting lines 3, 4 (represented here in dotted lines), for example made by microperforations, one of which extends under the strip 2.
• the cutting lines define on the sleeve a removable portion 5 which is removed when the sleeve is cut.
• the envelope of the invention is then threaded onto the neck of a container closed by a stopper, then heated to cause heat shrinkage of the sleeve on the neck of the container, covering at least one edge of the stopper.
• the whole forms an envelope that seals the cap on the neck.
• the only way to access the stopper is to tear the security envelope along the cut lines 3,4.
• the user grasps the upper end of the security band, which acts as a tear strip (also called tirecelle) and pulls on it.
• tear strip also called tirecelle
• FIG. 2 The result is then visible in FIG. 2 on which it can be seen that the removable portion 5 has been removed by being cut along the cutting lines 3,4, which has caused the delamination of the security strip 2, a part 2A of which is remained attached to the portion of the sleeve 1 remained in place on the container.
• the security band 2 is separated into several elements and it is no longer possible to redial, its constituent elements being delaminated and separated. It is then very difficult to try to put back the sleeve on the container.
• the sleeve 1 similar to that just described has security signs 20 (only one of which is illustrated here).
• the security band 2 also has security signs 21 (only one of which is illustrated here) which are arranged here on the secure coating of the material forming the safety band 2.
• the security signs 20, 21 of the sleeve 1 and the security band 2 may comprise, for example, a numerical code, a barcode, a QR-type code (two-dimensional barcode), a number, a holographic element , a logo ...
• the security signs on the sleeve 1 and / or the security strip 2 include data that is specific to the object that the security envelope is intended to cover.
• at least one of the security signs is established from a unique identification code that is specific to the object to be covered. The security sign thus varies from one object to another, which reinforces the security of the envelope.
• the security signs 20,21 are here arranged on the outer faces of the sleeve 1 and the safety band 2 so as to be visible when the security envelope of the invention covers an object. In this way, the various security signs make it possible to reinforce the security of the envelope.
• the security signs 21 carried by the security band 2 are destroyed or at least deteriorated due to the separation of the security band 2 into several elements. It is therefore extremely difficult to recompose the security signs by trying to replace the safety band 2 on the sleeve 1, which further enhances the security of the security envelope.
• the envelope comprises a security sign 23 which is arranged on the envelope so as to extend astride the outer face of the sleeve 1 and on the outer face of the security band 2.
• said security sign 23 is destroyed, or at least damaged, due to the separation of the security band 2 into several elements and the separation of the security band 2 from the rest of the sleeve 1.

• the safety signs 21 and 23 have been destroyed by the removal of said removable part 5.
• the various security signs are reported by any means on their respective supports. They can for example be printed on respectively the safety band 2 and the sleeve 1.
• the sleeve 1 similar to that just described, further comprises on its inner side 6 transferable impressions on the wall of the container which also form a safety sign. It may be for example logos (illustrated by the "A" in the figure) previously printed on the inner face of the sleeve 1, whose contour is microperforated.
• the surface of the prints 6 is preferably coated with heat-activated glue, also called heat-sensitive glue, so that when the sleeve is heat-shrunk, the portion of the sleeve that carries the impressions 6 is glued to the wall of the container.
• the surface of the transferable prints 6 may, however, be coated with any type of adhesive material allowing adhesion of the prints 6 to the wall of the container.
• the adhesive material can thus also be a cold glue.
• the prints extend under the security strip 2, and more particularly under the portion thereof which is removed with the removable portion 5 of the sleeve.
• the security sign has thus remained invisible from the outside until at the rupture of the sleeve. Indeed, we see in Figure 7 that the security sign is not visible from the outside as long as the sleeve is in place on the container.
