Description

The present invention relates to the field of packaging and in particular the safety devices for containing neck, and more particularly but not exclusively a container such as a bottle of wine or a spirits, or a bottle of perfume or drug. The invention aims more precisely a security sleeve (English "security sleeve") for such a neck container, with an opening indicator to highlight the opening of the bottle and possibly the filling of the with adulterated products. Many ways of securing a container with a safety sleeve have already been proposed.

Thus, US Pat. No. 6,254,134 discloses a cylindrical safety sleeve of a bottle, comprising an envelope made of a heat-shrinkable material, carrying a holographic element. The opening of the sleeve, to access a closure device covered by it, deteriorates the holographic element. EP-B-0 929 886 discloses a heat-shrinkable plastic sleeve, intended to be affixed to the neck of a bottle, partially covering the cap. The sleeve is provided with a holographic element and a tear strip. The holographic element is partially adhered to the glass of the bottle, and pulling the tear strip during a legitimate or fraudulent opening, residual fragments of the latter remain on the bottle. This device is relatively complex in manufacture.

GB-A-2,273,492 discloses a heat-shrinkable sleeve for use as a tamper evidence, carrying a holographic image visible from the outside. This sleeve is perforated along a line so as to make it difficult to remove without deterioration. European patent EP-B-0 812 451 discloses a heat-shrinkable film of tubular shape, carrying an optical writing providing an optically variable effect. The conditions of use of such a tubular film are not specified. The application WO-A-2014/023919 discloses a cap for a container such as a bottle, having a label placed inside the cap in an intermediate opening zone.

EP-B-0 929 886 discloses a cylindrical, heat-shrinkable safety sleeve disposed on a closure member and including a hologram.

EP-A-0 585 076 discloses a holographic safety device consisting of a thermoplastic film and an adhesive, for example in the form of a heat-shrinkable sleeve. European Patent EP-B-1 901 969 discloses a closure device comprising a screw cap and a tubular member of heat-shrinkable plastic material, which covers a side surface of the screw cap. Furthermore, the application EP-A-0 698 561 describes an object packaging envelope, made from a heat-shrinkable plastic sleeve, comprising a preferred cutting line. The envelope comprises, on its inner wall, a metal filament extending away from the preferred cutting line to remain on the envelope after cutting thereof. The filament constitutes an antenna for an electronic surveillance system operating on a magnetic detection principle. Finally, the application EP-A-0 698 562 discloses a tear strip for object packaging allowing the opening of the package, by tearing the wall constituting the package. The tear strip carries a metallic filament extending along the length of the strip. The filament constitutes an antenna for an electronic surveillance system operating on a magnetic detection principle. In both cases, however, the metal filaments are only intended to warn of an attempted robbery. These filaments do nothing to highlight an opening of the packaging envelope or packaging. In addition, there are security labels such as those marketed by the companies Prooftag or Tesa Scribos, allowing the traceability of bottles through the presence of a unique identifier. They are sometimes positioned astride the overcap and the neck of the bottle to highlight an opening of the bottle and provide a guarantee of inviolability. To remove the capsule from the bottle without damaging it and to access the wine, it is then necessary to take off the said label, making the adulteration of the wine more difficult. Nevertheless, these labels are relatively easily peelable and repositionable using known means (heating, solvents, etc.), without altering either the overcap or the label itself.

The invention aims to further improve the means for securely and securely authenticate containers neck, and to track the contents of these containers. To this end, the invention proposes a safety sleeve for a neck container, especially for a bottle or bottle, comprising a heat-shrinkable sleeve, at least one authentiable opening indicator affixed, at least at one point, on the inside face. of the heat-shrinkable sleeve, each authenticatable opening indicator extending along said heat-shrinkable sleeve, the heat-shrinkable sleeve and each authentiable opening indicator being shaped so that in case of stress on the heat-shrinkable sleeve causing a substantially circumferential tearing thereof, each authentiable opening indicator remains fixed only to one of the two parts of the heat-shrinkable sleeve delimited by the substantially circumferential tear.

Thus, according to the invention, in the event of stress on the safety sleeve likely to cause a substantially circumferential tear of the heat-shrinkable sleeve - as is necessary to unclog a container on which is fixed such a safety sleeve - the witness Authentic opening aperture remains attached to only a portion of the heat-shrinkable sleeve delimited by the substantially circumferential tear, preferably the portion torn from the container. Thus, even if the heat-shrinkable sleeve remains partially in place, the absence of the authenticatable opening indicator makes it possible to detect that an opening of the container has been attempted or made. The sleeve according to the invention thus has increased safety compared to a heat-shrinkable sleeve alone.

According to preferred embodiments, the security sleeve according to the invention comprises one or more of the following characteristics, taken alone or in combination: the authenticatable opening indicator has at least one authenticatable element; said at least one authenticatable element has appearance characteristics that are visible to the naked eye, in particular colored, metallic, holographic, with variable optical effect and / or alphanumeric inscriptions or characters and / or first-level security features; said at least one authenticatable element has security features of second level and / or third level; each authenticatable opening indicator is fastened, in particular glued, to the heat-shrinkable sleeve over the entire length of the heat-shrinkable sleeve or in at least one location, preferably two distinct locations of the heat-shrinkable sleeve, each in one of the two portions of the heat-shrinkable sleeve to be delimited by the substantially circumferential tear; the safety sleeve comprises at least one weakening line consisting of perforations and / or discontinuous notches and / or a continuous groove and / or discontinuous grooves; the safety sleeve comprises at least one circumferential weakening line extending along at least one angular sector of the heat-shrinkable sleeve, said circumferential weakening line being preferably intended to form at least part of said substantially circumferential tear; the safety sleeve comprises two circumferential weakening lines forming a tear strip, preferably with a gripping tab at the end of the tear strip; the safety sleeve comprises at least one axial weakening line, extending substantially in the longitudinal direction of the heat-shrinkable sleeve; the safety sleeve comprises at least two axial weakening lines, preferably extending on either side of each authentiable opening indicator; the circumferential weakening line or lines extend only between two axial weakening lines, in an angular sector of the heat-shrinkable sleeve that does not receive an authenticatable opening control; the security sleeve comprises: - a plurality of authentiable opening indicators attached to the heat-shrinkable sleeve, - at least one circumferential weakening line extending on either side of the authentiable opening indicators, on the perimeter of the heat-shrinkable sleeve or extending completely around the perimeter of the heat-shrinkable sleeve, in particular at a portion of the heat-shrinkable sleeve intended to be received at the level of a glass ring of the neck container; each authenticatable opening indicator is at least partially fixed, in particular glued, to the heat-shrinkable sleeve, in particular with adhesives having different adhesion properties, to one of the two parts of the heat-shrinkable sleeve intended to be delimited by the substantially circumferential tear, in particular on either side of the circumferential weakening line, where appropriate; each authenticatable opening indicator comprises an elongated element, a wire, a cable, a braid and / or a ribbon extending over the entire length of the heat-shrinkable sleeve and preferably carrying at least one element of security ; each authenticatable opening indicator has a thickness or a diameter greater than 0.01 mm, preferably greater than 0.5 mm, and / or less than 2 mm, preferably less than e) 1.5 mm; each authenticatable opening indicator has a width greater than 0.5 mm, preferably greater than 1 mm, and / or less than 5 mm, preferably less than 3 mm; at least one authenticatable opening indicator has a greater resistance to shear and / or torsion than that of the heat-shrinkable sleeve; each authenticatable opening indicator is made of a metallic material, in particular steel, made of a cobalt-based material, of a polymeric material, for example an aramid, a composite material, in particular a textile composite material; metal, textile / polymer, polymer / metal, polymer / filler, the filler may for example be mineral, in particular carbon, glass and a mixture of carbon and glass; the heat-shrinkable sleeve carries at least one security element; each safety element of the heat-shrinkable sleeve is in the form of an impression, a wire, a flat band, a foil or a patch, and is affixed to the inner or outer face of the heat-shrinkable sleeve or is integrated in the mass of the heat-shrinkable sleeve; the heat-shrinkable sleeve and / or each authenticatable opening indicator comprise at least one optically variable security element; and the security sleeve comprises at least two authenticatable opening indicators, the at least two authenticatable opening indicators preferably being angularly equiangular on the inner surface of the heat-shrinkable sleeve. According to another aspect, the invention relates to a security assembly of a container comprising a safety sleeve as described above in all its combinations and a cap, in particular of metal, in particular aluminum, arranged to partially cover only the safety sleeve after having been threaded on, in particular by stamping or crimping. The cap may leave visible a band of the safety sleeve to access the security elements of the heat-shrinkable sleeve and / or each authenticate opening indicator, if any. The invention also relates to a secure container comprising: a container, in particular a bottle or a bottle, with a neck, a device for plugging the orifice of the neck, and a safety sleeve as described above in all its combinations or a set of securing a container as described above in all its combinations, the heat-shrinkable sleeve at least partially covering the device for plugging the orifice in the neck.

The plugging device of the orifice of the neck may be a screw cap adapted to protect the container at a portion of at least the heat-shrinkable safety sleeve. The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended figures, in which: FIG. 1 is a diagrammatic representation of transparency a detail of a first example of secure container; - Figure 2 schematically shows in transparency the security assembly implemented in the secure container of Figure 1, seen from above; - Figure 3 schematically shows in transparency a detail of a second example of secure container; - Figure 4 schematically shows in transparency the security assembly implemented in the secure container of Figure 3, seen from above; FIG. 5 schematically shows in transparency a detail of a third example of secure container; - Figure 6 schematically shows in transparency the security assembly implemented in the secure container of Figure 5, seen from above; FIG. 7 schematically shows in transparency a detail of a fourth example of a secure container; - Figure 8 schematically shows in transparency the security assembly implemented in the secure container of Figure 7, seen from above; FIG. 9 schematically shows in transparency a detail of a fifth example of secure container; and FIG. 10 schematically represents in transparency the security assembly implemented in the secure container of FIG. 9, seen from above; and - Figure 11 shows schematically in transparency a detail of a sixth example of secure container; and - Figure 12 schematically shows in transparency the security assembly implemented in the secure container of Figure 11, seen from above. In the appended figures, the actual proportions of the various constituent elements or their spacings have not always been respected, for the sake of clarity. In addition, some elements may not have been represented in contact with each other, while they are in practice. In the remainder of the description, identical or identical elements of the different examples bear the same reference sign. For brevity of the present description, these elements are not described in detail with respect to each of the examples, only the differences between the various examples being described in detail. As illustrated in FIG. 1, a first example of a secure container 10 comprises a container 12 with a collar that has an orifice closed by a closure device, and a security assembly 14 placed over the closure device.

The container 12 is here a glass bottle having a base, a body and a neck terminated by a neck, opposite the base, with an orifice. The orifice is plugged by a closure device (not shown in the figures), for example a plug forcefully introduced into the neck. The neck has a glass ring, formed by an extra thickness of glass near the mouth of the neck. The bottle 12 is filled with a liquid, for example an alcoholic liquid such as wine. The container 12 is secured by means of a security assembly 14, which makes it possible to detect an attempt to open the bottle. In other words, the security assembly 14 does not allow the removal of the cap from the inside of the neck without damaging said security assembly 14. Such a withdrawal leaves on the security assembly 14 a mark later visible by a consumer. The security assembly 14 here comprises a security sleeve 16 covered with a cap 18 (or "overcap capsule"). Here, the cap 18, opaque, covers only partially the safety sleeve 16 and leaves visible a band of the safety sleeve 16. The band of the safety sleeve 16 left visible by the cap 18 has for example a height of between 3 and 70 mm, preferably between 10 and 30 mm. The cap 18 is for example a stamped metal cap formed of a metal sheet in the form of a sleeve for covering, in particular, the neck and the orifice of the neck of the container 12. The cap 18 is for example made of aluminum, of aluminum alloy , tin or plastic. The safety sleeve 16 comprises, as illustrated, a heat-shrinkable sleeve 20 and an authenticatable opening indicator 22.

The heat-shrinkable sleeve 20 is for example of polymer material. It is affixed to the neck of the bottle 12 and after heating, it is retracted so that it matches the relief of the neck of the bottle 12, in particular the relief formed by the glass ring. The heat-shrinkable sleeve 20 extends between the shoulder of the bottle, that is to say the flared portion which connects the neck to the barrel, and the neck of the bottle 12. The heat-shrinkable sleeve 20 covers here the neck and at least partially the cap received therein to plug and protect the orifice of the bottle 12. The heat-shrinkable sleeve 20 has a socket shape. The heat-shrinkable sleeve 20 thus has substantially a cylindrical shape of revolution with an empty end surface, to slide the neck of the bottle, and an end surface at least partially full, to cover at least partially the device capping the bottle 12. The end surface at least partially full facing the closure device may have substantially an annular shape, perforated in the middle. In the case where the container is intended to receive wine, or a content to exchange with the air, it is preferable that the end surface is perforated. The heat-shrinkable sleeve 20 may have, in its lower part, oriented towards the base of the bottle 12, on its surface containing side and / or on its surface opposite the container, decorative elements such as gilding for example and / or informative elements, for example type one or two dimensional code such as QR code and / or brand or product names (not shown). In addition, as illustrated, the heat-shrinkable sleeve 20 has, in its lower part, oriented towards the base of the bottle 12, on its surface containing side (that is to say internal or facing the container). In the present case, two such security elements are represented, without this number being limiting. Of course, the increase in the number of security elements increases the difficulty of reproducing the sleeve in the same way. 20. The security elements 25 or at least some of them are made on the heat-shrinkable sleeve 20 so as to remain visible even after the introduction of the cap 18. The security elements 25 may present a so-called first, second or third level security feature. "Top-level security feature" means a security feature visible to the naked eye, in daylight or artificial light, without the use of a particular device. Such a first-level security feature can be a variable optical effect, such as for example producing interferential platelet particles, magnetic or not, liquid and / or oriented and / or photonic crystals, a holographic element or a network of lenses in combination with underlying pattern, all of which are thus adapted to form a security element with a first-level feature. By "second level security feature" is meant an optical effect always visible to the naked eye, but only with the aid of a relatively simple device, such as a lamp emitting in the ultraviolet (UV), the visible or the infrared (IR) or a magnifying glass or a decoding tool of the optical filter type or a polarizing filter. For example, a security element with a second level characteristic is luminescent, that is to say, for example, that it has a specific emission in the visible under the lighting of a Wood lamp emitting in the light. ultraviolet, for example still at a wavelength of 365 nm. Another example of a security element with a second-level characteristic is an anti-stokes element, that is to say having a specific emission in the visible under the illumination of an IR pointer, for example to a length 980 nm wave. A second-level feature may also be a feature of a security element that is revealed in case of heat and / or friction input. Finally, by "third-level security feature" is meant a security feature requiring for its detection a dedicated detection device. An element exhibiting a third-level security feature is for example capable of generating a specific signal when it is simultaneously or not subjected to one or more sources of external stress. This signal is processed and analyzed by a dedicated detection device for authentication or identification of the security element. Other examples of security elements having a third-level security feature are tracers or materials in the form of active materials, particles or fibers, capable of generating a specific signal when these tracers are subject to a mechanical, thermal, photonic, optronic, electrical, magnetic or electromagnetic stress. The safety element or elements 25 on the heat-shrinkable sleeve 20 may be in the form of an impression, a wire, a flat band, a foil or a patch, affixed preferably on the inner face of the heat-shrinkable sleeve 20. The safety element or elements can also be integrated in the polymer mass of the heat-shrinkable sleeve 20. One or more additional security elements can also be visible only on the outer face of the thermo-shrinkable sleeve. The retractable element (s) may be printed in particular. Indeed, the heat-shrinkable sleeve 20 can be obtained from a folded film on itself followed by a meeting of two free edges. This film, before folding, can be printed by well-known printing processes, such as gravure, screen printing, flexography, digital printing, inkjet or offset. The film may be printed with first, second and / or third level security inks in the lower portion of the heat-shrinkable sleeve 20 which remains visible after retraction of the heat-shrinkable sleeve 20 on the bottle to be protected and set up. The cap 18. An impression can also be made with a swelling ink, which thus creates a relief on the heat-shrinkable sleeve. The security prints present on the sleeve 18 are preferably made in such a way that they remain visible and / or detectable after insertion of the device for plugging the orifice of the bottle 12 and retraction of the heat-shrinkable sleeve 20 on the bottle. 12, relying on anamorphosis techniques.

The heat-shrinkable sleeve 20 may in particular comprise the following security elements, alone or in combination: dyes and / or luminescent pigments and / or interferential pigments and / or liquid crystal pigments, especially in printed form or mixed with a constitutive material of the sleeve, - components, dyes and / or photochromic or thermochromic pigments, arranged to indicate the temperature of the container and therefore approximately that of its contents, in particular in printed form or mixed with a constituent material of the sleeve, - an interferential multilayer film, - a structure with variable optical effects based on interference pigments or liquid crystals, - a birefringent or polarizing layer, - a diffraction structure, - an embossed image, - a partially reflective refractive element, a foil metallized, gonio-chromatic or holographic, an optical effect layer variable based on interference pigments or liquid crystals, particles or agglomerates of pigment particles or dyes of the HI-LITE type, visible or non-visible to the naked eye, in particular luminescent, safety fibers, in particular metallic fibers, magnetic (magnetically soft and / or hard), or absorbing, or excitable to ultraviolet, visible or infrared, and in particular the near infrared (NIR), an automatically detectable tracer having specific and measurable luminescence characteristics (eg fluorescence, phosphorescence), light absorption (eg ultraviolet, visible or infrared), Raman activity, magnetism, microwave interaction, RF interaction, X-ray interaction, Terahertz, electromagnetic response or electrical conductivity. The heat-shrinkable sleeve 20 may furthermore comprise, preferably in its part not covered by the cap 18, at least one visible authentication element, such as for example a holographic foil, OVI type variable optical effect safety impressions. , in relief - in particular made with a swelling ink - or authenticatable recognition elements dispersed in the material of the sleeve. The heat-shrinkable sleeve 20 may comprise temperature indicators such as, for example, thermochromic elements, in particular liquid crystals and / or pigments and / or thermochromic dyes, which can change appearance at at least one predefined temperature. . The container may then comprise at least one information associated with the thermochromic elements, providing information on the temperature of change of appearance of the thermochromic elements, qualitatively and / or quantitatively, and thus on the temperature of the container and approximately that of its content. The appearance of the thermochromic elements, for example their coloration or their transparency, varies according to the temperature to which they are subjected. The process of varying the appearance of the thermochromic elements is preferably reversible. The information may correspond to the numerical value of the change of appearance temperature of the thermochromic elements. The heat-shrinkable sleeve 20 may also comprise in its lower part not covered by the cap 18, at least one identifier of the unit identification code type having a tracking and traceability function (function called "Track & Trace" in English). , such as for example a two-dimensional bar code, EAN128 barcode type, a Datamatrix two-dimensional barcode or an alphanumeric code written in clear. This code may or may not be encrypted. This identifier or code may be marked by any means, for example by etching or by printing and preferably by means of a visible iridescent ink or an invisible ink containing, for example, UV luminescent pigments, as described in EP 1 307,520 and EP 1 864 113, thereby realizing a tracking and traceability function as well as an authentication function. The heat-shrinkable sleeve 20 may also comprise in its lower part not covered by the cap 18 at least one visible two-dimensional code type "quick response" (QR) or Datamatrix, for addressing, via a communicating device such as a telephone (smartphone type for example), a website of the producer or the certifying body via which any actor in the chain including the consumer can collect information on the content and proceed to a verification of the identifier written on his bottle. The heat-shrinkable sleeve 20 may also comprise in its lower part not covered by the cap 18 at least one augmented reality printing capable of interacting with a specific software application loaded into a "smartphone" or into a tablet or any other portable device .

The heat-shrinkable sleeve 20 may also have in its lower part, in particular at the level of the security elements and / or the identifier, an opaque appearance providing sufficient contrast, in particular for the automatic authentication of the security element and / or the automatic identification of the identifier. Preferably, the lower part of the heat-shrinkable sleeve 20 has at the level of the unit identification code and / or the two-dimensional code, for example a QR code, a sufficient contrast to allow its automatic reading. This contrast can be provided by a localized printing background at the code or present over the entire surface, preferably on the inner face of the sleeve in contact with the glass facing the code. This contrast can be brought in particular by an opaque printing having a different color from that used for marking. The heat-shrinkable sleeve 20 may also serve to convey information storage means such as a chip, a radio frequency antenna, a magnetic strip and / or an optical memory. For example, an occulting layer comprising security elements for authentication purposes can be printed / deposited on the inner face of the heat-shrinkable sleeve 20 and serve to conceal an RFID chip, an antenna and / or security elements of the Authentic opening indicator located between the heat-shrinkable sleeve and the container. The security elements may also include a code that is found elsewhere than on the heat-shrinkable sleeve, for example on or in the secure container, for example in the inner part of the closure device, so that the content can not be authenticated. only once the container opened. The occulted code can also serve as a key to access a database that when accessed by means of this code, returns a second code that is written elsewhere on or in the container. The second code received from the database can thus be compared to a second code written on the container to authenticate the content. Alternatively, a code may be present on the lower part of the sleeve so as to be legible, and on the upper part of the sleeve, hidden under the cap, preferably the part of the sleeve which is removed when the container is opened, which facilitates the comparison of the two codes. The safety sleeve 20 may further comprise a unit identification code enabling a container tracking function, in particular in the form of a two-dimensional barcode of the Datamatrix type. The unit identification code can be printed with a black ink on the outer face of the sleeve after its retraction on the container, the printing providing sufficient contrast on the printing background of the heat-shrinkable sleeve 20 to allow its automatic reading . The heat-shrinkable sleeve film 20 may also be printed for decorative purposes with an opaque, color-coded print background having inscriptions in the name of the castle for example. The heat-shrinkable sleeve 20 may especially be made of one of the following plastics: PVC, HR PVC, PET, PETG, PS, OPS (oriented polystyrene), OPP (oriented polypropylene), TPEG, TPE S, PLA (acid polylactide), EPS (expanded PS). The heat-shrinkable sleeve 20 may have on its inner or outer surface a primer or varnish, for example hot-activatable, allowing increased adhesion between the heat-shrinkable sleeve 20 and the bottle to be protected and / or between the heat-shrinkable sleeve. 20 and the cap 18. The heat-shrinkable sleeve 20 here comprises an embrittlement line 24 extending over a portion of the circumference of the heat-shrinkable sleeve 20, defining a reserve above the opening indicator 22. In other words, the weakening line 24 extends here along an angular sector of the heat-shrinkable sleeve 20 that does not include an authenticatable opening indicator to facilitate tearing and training in case of opening of the container. The circumferential weakening line 24 is here formed by forming discontinuous notches in the heat-shrinkable sleeve 20, the notches extending substantially in a line. The notches are preferably formed on the heat-shrinkable sleeve 20 before it is put in place on the bottle 12. The weakening line 24 divides the heat-shrinkable sleeve 20 into two parts: a so-called upper part 20a, oriented towards the neck of the bottle 12, and a so-called lower portion 20b, oriented towards the base of the bottle 12. The safety sleeve 16 is here shaped so that the weakening line 24 is located just above the glass ring of the bottle 12, that is to say that the weakening line 24 extends, relative to the axis of the safety sleeve 16, between the canopy ring of the bottle 12 and the orifice of the bottle 12 when the safety sleeve is attached to the neck of the bottle 12. The security sleeve 16 also comprises an authentiable opening indicator 22 extending along the heat-shrinkable sleeve 20, in particular between the upper end of the heat-shrinkable sleeve, of positioned to be located substantially at the opening in the container, and a portion of said heat-shrinkable sleeve 20 not to be covered by the cap 18. Here, the authentiable opening indicator 22 extends over the entire length of the heat-shrinkable sleeve, that is to say between its two opposite ends. Alternatively, it may also extend beyond the end of the heat-shrinkable sleeve oriented towards the base, so as not to be covered by the heat-shrinkable sleeve or by the cap 18. Here, the opening authenticatable witness is an element attached to the heat-shrinkable sleeve in the form of a strip 22 having an authenticatable element 29, in particular in the lower part 20b not covered by the cap 18, this authenticatable element having for example characteristics of appearance visible to the naked eye, in particular colored, metallic, holographic, with variable optical effect and / or alphanumeric inscriptions or characters and / or first-level security features. The authenticatable opening cookie may alternatively or additionally include one or more second-level and / or third-level elements for its authentication.

The authenticatable element 29 of the band 22 is preferably still visible or detectable after the introduction of the safety sleeve on the container and even after the introduction of the cap 18 on the heat-shrinkable sleeve 20. Here, this is achieved by placing the authenticatable element 29 at the level of the band of the safety sleeve 16 left visible after the cap 18 has been put in place. The heat-shrinkable sleeve may alternatively bear, on its external face, a layer masking covering the authenticatable element 29, accessible after removal of the masking layer. The masking layer may be a layer of an opaque coating to be scraped off. The masking layer may also be opaque to the visible wavelengths, but transparent to the wavelengths outside the visible, thus making it possible to reveal the authenticatable element 29. In a variant, the heat-shrinkable sleeve has a notch or a notch. window leaving the band 22 and in particular the authenticatable element 29 accessible, especially visible from the outside. According to yet another variant, the authenticatable element 29 is placed on a portion of the strip 22 projecting from the heat-shrinkable sleeve 20. By "strip" is meant an element having a very elongated shape. In particular, the band 22 may be ten times, preferably twenty times, more preferably fifty to five hundred times longer than wide. The band has a length greater than that of the cap. The band 22 may in particular have a width greater than 0.5 mm, preferably greater than 1 mm, and / or less than 5 mm, preferably less than 3 mm. The band 22 may also have a thickness greater than 0.01 m, preferably greater than 0.5 mm, and / or less than 2 mm, preferably less than 1.5 mm. The strip 22 is fixed integrally on the radially inner surface of the heat-shrinkable sleeve 20, that is to say on the surface containing side. The band 22 is fixed on the heat-shrinkable sleeve so that in case of force exerted on the safety sleeve 16 causing a substantially circumferential tear of the heat-shrinkable sleeve 20 and causing at least partial separation of the upper part 20a of the lower part 20b, the authentiable opening indicator 22 remains secured to the upper part 20a only and is separated from the rest of the heat-shrinkable sleeve 20, so that the authenticatable opening indicator 22, with the authenticatable element 29 conveyed, is no longer visible or detectable on the container, in particular in the visible lower part protruding beyond the cap 18. Here, to do this, the band 22 forming an authenticatable opening indicator is partially fixed on the surface radially internal of the heat-shrinkable sleeve 20. More specifically, the strip 22 extends substantially along the length of the heat-shrink sleeve The strip 22 is glued to the radially inner surface of the heat-shrinkable sleeve 20 at two distinct portions 26, 28. The first portion 26 is located above the glass ring in the upper part of the heat-shrinkable sleeve 20a facing the orifice of the bottle 12 while the second portion 28 is located in the lower part of the heat-shrinkable sleeve. 20b oriented towards the base of the bottle. Also here, the first portion 26 extends between the top of the neck of the bottle and the perimeter of the glass ring of the bottle 12 facing the neck of the bottle. In other words, as shown, the bottle being placed on its base, the neck upwards, the first zone 26 extends from the bottom of the glass ring to the neck. Here, the first zone 26 is located substantially at the upper portion 20a of the heat-shrinkable sleeve 20, while the second portion 28 is located at the lower portion 20b of the heat-shrinkable sleeve 20. The strip 22 is example in Kevlare so that it is possible to cut or tear the heat-shrinkable sleeve 20, in particular along the weakening line 24, without harming the mechanical integrity of the strip 22, especially without cutting it. The band 22 is thus able to perform the function of opening witness. In particular, even if a tool, such as for example a knife, or a capsule cutter is used to separate the two portions 20a, 20b of the heat-shrinkable sleeve 20 along the weakening line 24 or at the level of the glass ring, the strip 22 is not severed.

In addition, here, the two portions 26, 28 of the strip 22 are preferably bonded to the radially inner surface of the heat-shrinkable sleeve 20. Cold glues, "hotmelt" adhesives and / or adhesives sensitive to pressures and / or thermoactivables can in particular be used. Alternatively, the two portions 26, 28 of the strip 22 are secured to the sleeve by any other means, for example by welding, thermal, mechanical or chemical process. The adhesives used for bonding the two portions 26, 28 to the heat-shrinkable sleeve 20 have different adhesion properties, chosen such that a pull or twist on the upper portion of the heat-shrinkable sleeve 20a causes the sleeve to tear. heat-shrinkable 20 in at least two parts, in particular along the line of weakness 24, also causes detachment or tearing of the strip 22 at the portion 28 of the heat-shrinkable sleeve 20. This can for example be achieved using a permanent glue for adhering the first portion 26 of the strip 22 to the heat-shrinkable sleeve 20, and a semipermanent glue for bonding the second portion 28 of the strip 22 to the heat-shrinkable sleeve 20, the heat-shrinkable material of which is makes the heat-shrinkable sleeve 22 being preferably chosen to have a tensile strength greater than the adhesive strength and the resistance to the stress of the semi permanent glue implementation.

By "permanent membership" is meant here a definitive link between two parties to join. By "semi-permanent adhesion" is meant here a temporary connection between two parts to join allowing one of the two parties to be removed. Semi-permanent glues are adhesives that show low adhesion. Preferably, the adhesive power of the permanent glue is greater than the pulling force that could be exerted to open the container. For example, the heat-shrinkable sleeve 20 is made of PET, the adhesive used to bond the first portion 26 of the strip 22 to the heat-shrinkable sleeve 20, is of polyurethane type and the adhesive used to bond the second portion 28 of the strip 22 to the heat-shrinkable sleeve 20 is of acrylic type. This type of glue advantageously has a grip force just necessary for setting in position the authentiable opening indicator. Thus, when opening the bottle, after cutting and removal of the upper portion 20a at least of the cap 18, the cutting and removal of the upper portion 20a of the heat-shrinkable sleeve 20 and / or the extraction the plug causes a separation of the upper portion 20a of the heat-shrinkable sleeve 20a at the line of weakening 14 and tearing of the strip 22 of the lower portion 20b of the heat-shrinkable sleeve 22 at the second portion 28 glued to the heat-shrinkable sleeve 20 with an adhesive less resistant than the first portion 26. A user can then determine that an opening of the container has taken place by the absence of the authenticatable opening indicator 22 and its authenticatable element 29 at of the lower part 20b of the heat-shrinkable sleeve protruding from the cap 18. FIG. 3 illustrates a second example of a secure container 50. This second example 50 is different from the first example 10 essentially in that two authenticizable opening witnesses 22 in the form of a strip are partially fixed on the inner surface of the heat-shrinkable sleeve 20. These two authentiable opening indicators 22 extend along the heat-shrinkable sleeve 20 symmetrically with respect to the axis of the heat-shrinkable sleeve, as is particularly visible in FIG. 4. Of course, other configurations are possible for the two authenticatable opening indicators 22. The multiplication of the number of opening authentiable makes it all the more difficult the reproduction of such a safety sleeve and the reuse of said sleeve after opening the container. The different authenticatable opening indicators are preferably equidistributed angularly on the inner surface of the heat-shrinkable sleeve 20. FIG. 5 illustrates a third example of a secure container 100. This third example of a secure container 100 differs from the first and second examples of secure containers. 10, 50 essentially in that the safety sleeve 16 is shaped so that the line of weakness 24 extends circumferentially over the entire perimeter of the bottle including at the level of the strip 22, with respect to the axial direction of the thermo sleeve. retractable 20, this time at the level of the glass ring of the bottle 12, between the upper perimeter of the ring oriented towards the neck and the lower perimeter of the ring oriented towards the base. In addition, this weakening line 24 is here produced in the form of discontinuous notches 102 in the heat-shrinkable sleeve 20. The notches 102 here taking the form of alternating wavelets, that is to say arcs of circles of which the concavity is oriented alternately towards the neck and toward the base of the bottle 12 (or towards one end and the other end of the heat-shrinkable sleeve 20). Alternatively, however, the weakening line 24 in this embodiment may also extend only over a circumferential sector of the heat-shrinkable sleeve 20 not receiving the authenticatable opening witness 22. Furthermore, it is also noteworthy that in this example of Figures 5 and 6 also, the first portion 26 of the strip 22 extends from the top of the neck of the bottle 12 to the weakening line 24 not included. In other words, as shown, the bottle being placed on its base, the neck upwards, the first zone 26 extends above the line of weakness 24. A fourth example of secure container 200 is illustrated on Figure 7. This secure container 200 differs from secure containers 10, 50, essentially in that the weakening line 24 here takes the form of a tear strip with at its end a gripping tab. The safety sleeve 16 is here shaped so that the tear strip 24 extends axially at the level of the canopy ring of the bottle 12 when the safety sleeve 16 is fixed on it. The tear strip facilitates the opening of the bottle and the removal of the upper portion 20a of the heat-shrinkable sleeve 20b by a user. A fifth example of a secure container 300 is shown in FIG. 9. This fifth example of a secure container 300 differs from the second example 50, essentially in that it comprises, in addition to the circumferential weakening line 24, two axial weakening lines. 30, 32 in the heat-shrinkable sleeve 20, on either side of the two authenticizable opening indicators 22. These axial weakening lines 30, 32 extend substantially parallel to the axis of the heat-shrinkable sleeve 20. The axial weakening lines 30, 32 may be made in the same manner as the circumferential weakening line 24. As illustrated, the axial weakening lines 30, 32 extend axially over only a portion of the length of the heat-shrinkable sleeve. 20, in particular from the lower end of the heat-shrinkable sleeve 20b to the circumferential weakening line 24. In a variant, however, the axial weakening lines 30, 32 extend axially over the entire length of the heat-shrinkable sleeve 20. In this fifth example, the two authenticatable opening indicators are completely fixed, in particular glued with a permanent glue on the entire length of the heat-shrinkable sleeve 20, so that the tearing of the heat-shrinkable sleeve 20 along the weakening lines and / or the extraction of the plug causes tearing of the upper part of the heat-shrinkable sleeve 20 and the two controls opening 22 authenticated with the portion of the heat-shrinkable sleeve 22 located between the two axial weakening lines. With such axial weakening lines, the tearing of a heat-shrinkable sleeve may be accompanied by a local tear of the portion of this heat-shrinkable sleeve remaining on the bottle 12. This further facilitates the determination of an opening of the bottle by a user since such an opening leaves a visible mark on the portion of the heat-shrinkable sleeve 20 remained on the bottle 12 The two authenticatable opening indicators 22 extend along the sleeve, they are preferably positioned symmetrically as in the second example but the strips are this time secured permanently along their entire length with the heat-shrinkable sleeve 20. The axial weakening lines 30, 32 extend here substantially parallel to the axis of the thermo sleeve -retractable 20 to the line of weakness 24 extending along a circumferential section of the heat-shrinkable sleeve 20 not receiving the s login credentials authentiable. Tear primers of the U-shaped heat-shrinkable sleeve 20 are thus formed. The circumferential weakening lines 24 extend here, depending on the perimeter of the heat-shrinkable sleeve 20, substantially at the lower perimeter of the glass ring oriented towards the base of the bottle. The cutting primers, made around the authenticatable opening indicator 22, thus facilitate the complete removal of the two authenticizable opening indicators 22, in the event of an attempt to remove the upper part 20a of the heat-shrinkable sleeve 20 and / or extraction of the cap of the bottle 12. Of course, it is possible to provide configurations having more than two authenticatable opening indicators. In the case of the example of Figures 9 and 10, the formed primers further facilitate the tearing of the upper portion 20a of the heat-shrinkable sleeve 20, which remains here secured to heat-shrinkable sleeve strips 20 receiving the controls. authenticated openings 22.

Finally, the example 400 of FIGS. 11 and 12 differs from the example of FIGS. 1 and 2 essentially in that it straddles the lower part 20b of the heat-shrinkable sleeve 20 and on the lower part of the witness opening authenticatable 22 not covered by the cap 18 a pattern 402, here a cloud shape for purely illustrative and not limiting This pattern 402 comprises three portions, two portions 404, 408 made on the radially inner surface of the heat-shrinkable sleeve 20 and a portion 406, here central serving authenticatable element 29, made on the upper face of the authenticatable opening indicator 22. Thus, in case of removal of the authenticatable opening indicator 22, the portion 406 with the authenticatable element 29 is torn off and the pattern 402 becomes incomplete. Of course, other patterns or inscriptions may be considered. It can also be provided a succession of alphanumeric characters forming a word or a product or brand name rather than a pattern Alternatively, also, the authenticatable opening indicator 22 has an authenticatable element 29 in the form of a colored area printed on its radially inner surface, facing the container, of a certain color. This colored zone is located for example at the portion of the heat-shrinkable sleeve 20 not covered by the cap 18. The heat-shrinkable sleeve 20 comprises on its inner wall, an inscription for example the word "void" of the same color that the colored area and arranged in a manner superimposed on the colored area of the opening indicator authentiable so as not to be visible. Thus, in the event of withdrawal of the authenticatable opening indicator 22, the colored zone of under the inscription is torn off and makes the word "void" appear.

The invention is not limited to the embodiments described above and many variants are possible. The various embodiments described can in particular be combined. Thus, the container is not limited to a bottle and can take other forms, such as that of a bottle. The content may also be varied and is not limited to wine or alcohol and spirits, but may in particular be perfume or active or medicinal substances. The closure device of the container may also take other forms than that of a plug inserted in the neck, as described above. It can thus be, for example, a cap or a screw cap on the neck, the latter then having a screw thread. The screwed cap protects the container at its opening. It can also be a capsule set on the neck of the bottle or partially inserted in the neck of the bottle. The security assembly implemented in the context of the secure container for detecting an attempt to open the container, then allows to detect a withdrawal or an attempt to remove the cap or screw cap. The circumferential embrittlement line may also take different forms, its function being essentially to create a tear initiation of the heat-shrinkable sleeve 20. The circumferential embrittlement line may thus extend along one or more disjointed angular segments of the heat-shrinkable sleeve. 20. It may also extend helically on the heat-shrinkable sleeve 20. It may also be formed of cuts through or not the heat-shrinkable sleeve 20 or a groove in the heat-shrinkable sleeve 20. The Authentic login credentials can also have many different configurations. It may thus be, for example, a strip of material, as described, a wire, a cable, a braid or a ribbon. It then has for example a thickness of between 0.01 mm and 2 mm, for example still between 0.5 mm and 1.5 mm and a width of between 0.5 mm and 5 mm, for example still between mm and 3 mm. mm. In the case of a wire or a cable, the latter has a diameter of between 0.01 mm and 2 mm, for example still between 0.5 mm and 1.5 mm.

The authentiable opening indicator is preferably in a material that can remain intact despite the tearing of a portion of the heat-shrinkable sleeve to which it is attached. To do this, the authenticatable opening indicator may in particular be made of a material such as Kevlare, as mentioned above, or, more generally, of aramid material, in particular comprising aramid fibers. The authentiable opening indicator may also be made of metallic material, in particular steel, cobalt-based material or polymers. It may also be made of a composite material, in particular textile / metal, textile / polymer, polymer / metal, polymer / mineral fillers, the mineral fillers may in particular be carbon or glass. The authenticatable opening indicator advantageously has a high tensile strength, in particular a tensile strength greater than 3 100 MPa (corresponding substantially to the tensile strength of the Kevlar), for example even greater than 5000 MPa (corresponding to substantially to the tensile strength of glass fibers), for example more than 7000 MPa (corresponding substantially to the tensile strength of carbon fibers). The material of which the authenticatable opening control is made can also have a high shear strength; it may in particular have a shear modulus greater than 70 GPa, for example still greater than 125 GPa, or, for example, greater than 520 GPa. The authenticatable opening indicator may also have (or be treated to exhibit) a low coefficient of friction with the container. It can thus, for example, be covered with a slip agent, such as a wax. This facilitates the removal of the opening indicator (s) that can be authenticated in the event of tearing off part of the heat-shrinkable sleeve. The authenticatable opening indicator 22 can also be authenticated by means of a simple printing - positive or negative - colored, especially at the zone level of the heat-shrinkable sleeve not covered by the cap, printing which appears or disappears after tearing.

According to a variant not shown, the authentiable opening indicator and the heat-shrinkable sleeve also has at least one authentication security, for example in the form of redundant security elements on each of them or similar patterns. According to a variant not illustrated also, the authentiable opening indicator 30 and the heat-shrinkable sleeve comprise at least one complementary security element. For example, an impression can be made on the lower part of the heat-shrinkable sleeve opposite the opening indicator 22, so as to be revealed only in case of tearing of the authentiable opening indicator. According to another example, an impression is made partly on the heat-shrinkable sleeve and partly on the authentiable opening indicator, so that printing is incomplete in case of tearing of the authentiable opening indicator.

Furthermore, the bonding areas 26, 28 may be limited in length. As a variant, however, the authenticatable opening indicator 22 may be glued over substantially the entire length of the heat-shrinkable sleeve 20. Finally, the heat-shrinkable sleeve may be embossed in a hollow to receive the authentiable opening indicator without forming an excess thickness of the outer surface.

The phrase "with one" should be understood as being synonymous with "having at least one".
