Description

Technical field

The invention relates to a protective shell, in particular for vessels, configured to provide protection against opening. The invention also relates to an article coated with such a protective sheath, and to a method for applying at least one information to a sleeve and / or to a protective strip of such a protective sheath.

State of the art

In some areas, it is necessary to provide devices on the vessels to ensure their protection against opening, in particular, to resist falsifications such as trademark substitution. For example, the neck of a vessel equipped with a stopper is closed with a sleeve of heat-shrinkable plastic material. To open the vessel, it is necessary to remove the heat-shrinkable sleeve, which is equivalent to its destruction.

However, it was noted that some counterfeiters still manage to return the sleeve to its place or replace it with a new one, which they put directly on the vessel by heating. Therefore, it has been proposed to use improved bushings to increase protection against opening.

Thus, an improvement in opening protection was required. For this, in FR 2754375, the applicant proposed a protective shell comprising a sleeve of heat-shrinkable plastic material having on its inner surface a holographic element and a tear strip extending behind the holographic element in such a way as to tear the holographic element while opening the shell. The holographic element is made with the possibility of transfer to the opposite wall of the vessel, therefore, any manipulation with the protective shell leads to automatic destruction of the transferred holographic element.

In document FR 2778892, the applicant also proposed a protective shell of heat-shrinkable plastic material, which is equipped on its inner surface with a tear strip and a metallized identification strip that runs parallel to the tear strip and is located between the inner surface of the sleeve and the adhesive surface of the tear strip.

Object of invention

The invention is intended to offer a new protective shell, in particular for vessels, with a higher level of protection.

Disclosure of invention

To achieve this goal, a protective shell for coating the product, in particular a vessel containing a sleeve of heat-shrinkable plastic material, which has on its outer surface a protective strip of exfoliating multilayer material, the sleeve contains at least one cut line passing under the strip, is proposed.

During an attempt to remove the sleeve, it will break along the cut line, which will lead to at least partial delamination of the strip and to the appearance of a visible trace of unauthorized manipulation of the sleeve.

According to a particular embodiment of the invention, the strip is opaque, and the sleeve has printing elements on its inner surface that are transferred to the product wall and hidden by the strip.

Thus, protective information can be printed on the product, which the counterfeiter will not even suspect. After opening the sleeve, this information, which was transferred to the wall of the product, will become fully visible.

Also provided are a product coated with such a protective sheath, as well as a method of applying at least one information to the sleeve and / or protective strip of such a protective sheath.

The implementation of the invention

As shown in FIG. 1, the protective sheath in accordance with the invention comprises a sleeve 1 of heat-shrinkable plastic material cut from a sleeve made of a film of this material. On its outer surface, the sleeve 1 is equipped with a protective strip 2 of a layered multilayer material, which extends essentially along the forming sleeve, therefore, when the sleeve is put on the neck of the vessel, the strip is essentially vertical.

The sleeve is made, for example, of a single-layer polyester film (for example, PET), stretched in such a way as to give it a priority direction of shrinkage. In an alternative embodiment, the sleeve is made of a multilayer heat-shrinkable material. For example, the specified multilayer heat-shrinkable material consists of various exfoliating layers.

The protective strip 2 is cut out of a flat material consisting of various exfoliating layers, including one adhesive layer, which allows it to be glued on the sleeve 1. For example, a multilayer material is used that contains an adhesive layer, a polypropylene layer and an outer layer, in this case having protective coating on which protective signs can be applied. The outer layer can be made, for example, of paper, of plastic, or can be embossed with inscriptions.

Preferably, the laminate of the protective strip is not heat-shrinkable. This facilitates the application of protective signs on the protective strip. In addition, the part of the sleeve covered with a protective strip will shrink to a lesser extent than the rest of the sleeve, which also facilitates the possible application of protective signs on this part of the sleeve.

The sleeve 1 contains cut lines 3, 4 (shown by a dotted line) made, for example, in the form of microperforations, one of which is under the strip 2. The cut lines form a removable section 5 on the sleeve, which is removed during cutting of the sleeve. Then the sheath in accordance with the invention is put on the neck of the vessel, closed by a stopper, and then heated, which leads to heat shrinkage of the sleeve on the neck of the vessel, which at least partially covers the edge of the stopper. The entire complex forms a shell that seals the cork on the neck.

The only way to gain access to the plug is to break the protective sheath along lines 3, 4 of the cut. To do this, the user grabs the upper end of the protective strip, which acts as a tear strip (also called a grip), and pulls at this end.

The result is shown in FIG. 2, where it can be seen that the removable section 5 was removed along the cut lines 3, 4, which led to the delamination of the protective strip 2, part 2A of which remained connected to the section of the sleeve 1, which remained in place on the vessel. Thus, the protective strip 2 was divided into several elements, and it is no longer possible to restore it, since its constituent elements were stratified and divided. After that, it is very difficult to try to put the sleeve back in place on the vessel.

According to the first version shown in FIG. 3a, sleeve 1, similar to that described above, contains security signs 20 (of which only one is shown). In addition, the protective strip 2 also contains protective signs 21 (of which only one is shown), which in this case are made on the protective coating of the material forming the protective strip 2.

The security signs 20, 21 of the sleeve 1 and the security strip 2 may include, for example, a digital code, a barcode, a QR code (two-dimensional barcode), a number, a holographic element, a logo, etc.

Preferably, the security signs affixed to the sleeve 1 and / or to the protective strip 2 contain data specific to the product to be covered by the protective sheath. For example, at least one of the security signs is made on the basis of an identification code characterizing the product to be closed. Thus, the protective sign changes from one product to another, which increases the protection of the shell.

In this case, the protective signs 20, 21 are made on the outer surfaces of the sleeve 1 and the protective strip 2 and are visible when the protective shell in accordance with the invention covers the product. In this way, various security signs can enhance the protection of the shell.

In addition, when pulling on the protective strip 2, the security signs 21 applied to the protective strip 2 are destroyed or at least damaged due to the separation of the protective strip 2 into several elements. Therefore, it is extremely difficult to restore the protective signs, trying to put the protective strip 2 back on the sleeve 1, which further increases the protection of the protective shell.

According to a particular embodiment, the casing comprises a security sign 23 positioned in such a way that it covers the outer surface of the sleeve 1 and the outer surface of the security strip 2. Thus, when the security strip 2 is pulled, the said security symbol 23 is destroyed or at least damaged. the reason for the separation of the protective strip 2 into several elements and the separation of the protective strip 2 from the rest of the sleeve 1.

In FIG. 3b shows the result of the removal of the removable part 5 of the sleeve 2. The security signs 21 and 23 were destroyed when removing the specified removable part 5.

Various security signs are applied by any means to their respective substrates. For example, they can be printed respectively on protective strip 2 and on sleeve 1.

According to the second embodiment shown in FIG. 4 and 5, the sleeve 1, similar to that described above, further comprises printed elements 6 on its inner surface that are transferred to the vessel wall and also form a protective sign. It may be, for example, logos (shown in the figure in the form of the letters “A”) pre-printed on the inner surface of the sleeve 1, the contour of which is made in the form of microperforations. Preferably, the surface of the printing elements 6 is coated with a thermosetting adhesive, also called thermosensitive adhesive, therefore, when the sleeve is heat-shrinked, a part of the sleeve containing the printing elements 6 is adhered to the vessel wall. At the same time, the surface of the transferred printing elements 6 can be coated with any adhesive material that adheres the printing elements 6 to the vessel wall. The adhesive material may also be cold cured adhesive.

Preferably, the printing elements are located under the protective strip 2 and, in particular, under its section, which is removed together with the removable section 5 of the sleeve.

As shown in FIG. 6-8, when the indicated removable portion is removed, the printing elements remain on the wall of the vessel and mark the vessel itself: thus, the protective sign remains invisible from the outside while the sleeve remains on the vessel. Indeed, in FIG. 7 shows that the protective sign is not visible from the outside, while the sleeve remains in place on the vessel.

In FIG. 8 shows the result of partial removal of the sleeve, and FIG. 6 - the result of complete removal of the sleeve. The printing elements 6 remain on the surface of the vessel and become visible.

In an embodiment, portable printing elements may include a digital code, a bar code, a QR type code (two-dimensional bar code), a number, a holographic element, etc.

            Of course, portable printing elements can be located on a different part of the sleeve, other than the removable part.

Preferably, the security signs are designed in such a way that they break when pulled by the protective strip, and / or appear only when pulled by the protective strip. For this, the protective strip 2 is preferably opaque. Thus, portable printing elements 6 can be seen from the outside only if the protective strip 2 is in place on the sleeve 1.

For example, the protective strip may be made of transparent materials and contain at least one layer of opaque material, so that the entire protective strip is opaque. Preferably, a layer of opaque material covers at least the outer surface of the protective strip 2, that is, the visible surface with the protective strip 2 in place. Alternatively, the protective strip may comprise at least one layer of opaque material so that the entire protective strip is completely opaque.

Alternatively, the protective strip is completely transparent, that is, through it you can clearly distinguish objects. The protective strip can only be partially opaque, while part of the protective strip remains transparent.

The invention may include various options. Although it has been indicated above that the sleeve 1 and the protective strip 2 may contain security signs applied thereto, the sleeve and the protective strip may contain information in general, such as, for example, indications of the contents of the article coated with the protective sheath.

Information on the protective strip can be applied to one of the inner layers of the multilayer material forming the protective strip: in this way, information will appear only when the protective strip is divided into several elements. The security signs or information in general may be located on the outer surface and / or on the inner surface of the protective strip. Similarly, security signs or information in general may be located on the outer surface and / or on the inner surface of the sleeve.

In addition, the information printed on the sleeve may be located at least partially on the part of the sleeve covered with a protective strip. Thus, information will appear only when the protective strip is divided into several elements, if, of course, the elements of the protective strip remaining after pulling the protective strip are sufficiently transparent. Alternatively, the information can be arranged so that it overlaps the removable portion of the sleeve and the rest of the sleeve. Thus, when pulled by the protective strip, this leads to the removal of the removable area and, therefore, to the destruction of information.

The information applied to the sleeve or to the protective strip is arranged, for example, with respect to the cut lines and relative to the position of the information applied respectively to the protective strip or sleeve.

To apply information on the sleeve 1 and on the protective strip 2, the following method is preferably used:

- information is applied to the sleeve 1;

- on the sleeve 1 form a cut line;

- information is applied to the protective strip 2, taking into account the position of the information on the sleeve 1 and the position of the cut lines on the sleeve 1,

- the protective strip 2 is connected to the sleeve 1.

The security signs and, in general, the information printed on the protective strip 2 and on the sleeve 1, respectively, may be interconnected. For example, a security mark affixed to a sleeve may contain one specific product code coated with a protective sheath, and a security character affixed to a protective strip may contain another specific product code coated with a protective sheath.

The invention is not limited to the above description and may cover any version that is not beyond the scope defined by the claims.

In particular, although in this case, the cuts form a removable section that can be separated from the rest of the sleeve, it is possible not to make a detachable section and provide for at least one of the cuts to pass under the protective strip to guarantee its rupture and its separation in case of exposure on the sleeve.
