The present invention relates to a container (10) secured, having a neck (11) provided with a closure member (30) and a safety sleeve (20) having an envelope of a heat-shrinkable material, the sleeve being retracted on the collar and extending exclusively below the closure member when the container is vertical with the closure member upwards or being partially covered by the closure member, the safety sleeve having at least one element security (50).

Description

The present invention relates to the field of packaging and in particular the security devices for authenticating and / or identifying a container with a neck, and more particularly but not exclusively a container such as a bottle of wine or wine. a spirit, or a bottle of perfume or medicine.

The identification and / or authentication and / or traceability information is most often conveyed on a label affixed to the container, on the skirt of a capsule or via a direct printing on the container. This visible information is thus directly exposed to potential attacks by fraudsters whose purpose is to alter and / or modify the content of this information.

Many ways of securing a container using a sleeve have already been proposed. Thus, US Pat. No. 6,254,139 B1 discloses a sleeve for securing 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. GB Patent Application 2 273 492 A 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 0 812 451 B1 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 2014/023919 A1 discloses a cap for a container such as a bottle, having a label placed inside the cap in an intermediate opening zone. EP 0 929 886 B1 discloses a cylindrical, heat shrinkable safety sleeve disposed on a closure member and including a hologram. EP 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 1 901 969 B1 discloses a closure device comprising a screw cap, a tubular member of heat-shrinkable plastic material, which covers a side surface of the screw cap. The patent application FR 2 754 375 describes 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 glued to the glass of the bottle, and pulling the tear strip during a legitimate opening or attempted tearing, residual fragments of the latter remain on the bottle. This device is of relatively complex manufacture. GB Patent Application 2,298,391 discloses a heat-shrinkable film, which may take the form of a sleeve, having a substrate including a holographic element and layers of adhesive. This film is intended to be inserted between an object and its packaging, so as to highlight an alteration thereof.

In addition, security labels such as those marketed by the companies Prooftag or Tesa Scribos, allow 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 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 remove said label, making the adulteration of the wine more difficult. Nevertheless, these labels are relatively easily peelable and repositionable using known means, without altering either the capsule or the label itself. In addition, the known security means apply to the bottle already closed by a closure member, and do not allow traceability very upstream, 25 before the filling of the bottles or just after. There remains, therefore, a need for container security that is compatible, if desired, with a follow-up thereof before the filling operation and their closure. The invention aims to further improve the means for securely and securely authenticate containers with a closure device, in particular bottles of wine closed by a capsule, by providing a means of authentication and / or identification and / or traceability and a guarantee of inviolability, allowing a reliable detection of any fraudulent or abnormal manipulation of the container and / or its contents and / or information carried by the container and / or the sleeve, and this even before the filling operation of the container if desired. The invention responds to this need by means of a secure container having a collar with a closure member and a safety sleeve having an envelope of heat-shrinkable material, the sleeve being retracted over the neck and extending exclusively below the closure member when the container is vertical with the closure member upwards, or partially covered by the closure member, the safety sleeve having at least one safety element, 10 preferably at least partially visible to the naked eye from the outside. Because the safety sleeve does not cover the closure member, it does not have to be put in place after the filling and / or capping operation. Its possible presence on the cervix, prior to the capping operation, does not interfere with it.

For its installation, the heat-shrinkable safety sleeve is heated so that it retracts around the container, which ensures a good conformation to the relief of the neck. In addition, since the sleeve may be in direct contact with the material in which the neck is made, the sleeve may have good adhesion thereto, thus being more difficult to remove. If necessary, an adhesive layer may be applied between the neck of the container and the sleeve to provide enhanced cohesion between the two elements. The safety sleeve may be partially covered by the closure member. This may make it even more difficult to attempt to remove the safety sleeve. In addition, this constitutes visual evidence, easy to discern, of the presence on the container of the safety sleeve before the closing operation.

Alternatively, the safety sleeve extends completely below the closure member when the container is viewed vertically with the closure member at the top. The safety sleeve can then extend in the continuity of the closure member on the neck. In such a case, the sleeve may have been put in place before or after the plugging operation. Such a variant is particularly suitable when the closure member is constituted by a sealing cap tamperproof ring, and in particular to the closure caps which are crimped on the neck. Such capsules 3021637 4 comprise for example a threaded fixed portion intended to remain permanently on the neck of the bottle and a plug arranged to be screwed on the fixed part, the invention allows to convey and / or protect information of identification and / or authentication and / or traceability on the container. The heat-shrinkable security sleeve 5 preferably contains this information on an inner face of the envelope, the containing side, not accessible from the outside. This information is not exposed to potential fraud. The security sleeve may carry, on an outer face, a masking layer at least partially covering an underlying information, accessible after removal of the masking layer. The masking layer may be a layer of an opaque coating to be scraped off. The closure member may comprise a screw cap or alternatively a crimped capsule. By "closure member", it is necessary to understand the closure device which ensures once in place the preservation of the contents present in the container. The closure member may thus be different from a plug inserted into the neck of the bottle. The capsule may comprise a tubular skirt partially covering the safety sleeve. This tubular skirt is typically made of metal or plastic, and it is connected to the rest of the capsule by a weakened zone. The rupture of this zone constitutes an opening witness.

The closure member may be covered with an overcap, which may or may not cover the safety sleeve. The security element is preferably optically variable. It may be advantageous for the safety sleeve to have on its inner side a control layer arranged to remain partly on the neck and to remain partly on the sleeve in the event of an attempt to detach the sleeve. This can make it possible to highlight an attempt at fraud by cutting the sleeve and then reassembling it on a container. The control layer preferably comprises two distinct zones consisting of respective adhesives having different respective adhesion forces, one of these zones preferably being in the form of an alternative or additionally, the control layer has a cohesive force. less than or equal to the adhesion force on the sleeve and the neck, so that the control layer delaminates in the event of an attempt to detach the sleeve.

The sleeve may comprise at least one code, preferably two-dimensional, preferably visible in daylight, in particular of the "quick response" (QR) or Datamatrix type, this code comprising a link readable by a communicating device such as a telephone, of the Smartphone type in particular, and making it possible to access a website of a producer or a certification body, via which any actor in the chain including the consumer can collect information on the content and proceed a verification of an identifier directly written on the container or elsewhere on the sleeve and / or on a label and / or on another element carried by the container.

The container is preferably a bottle, especially of glass, preferably filled with a beverage such as wine. The invention also relates to a method for securing a container, in particular a bottle of wine, comprising a neck, in which: A safety sleeve according to the invention, as defined in FIG. above, it causes the thermo-retraction of the sleeve, optionally, the closure member is reported on the neck, if it is not already present on the neck of the container. Indeed, the closure member may in some cases already be present on the neck when the safety sleeve is put in place. The closure member may be formed on the neck, in particular when the closure member is a screw cap. In a variant, the closure member is formed before it is put in place on the IC, in particular when the closure member is a crimped capsule, comprising, for example, a fixed plastic part defining a thread 25 and a cap screwed onto the cap. fixed part. The closure member may partially cover the safety sleeve during its introduction. In particular, the tubular skirt of the capsule, located under the weakened zone which is broken at the opening, can cover by its lower part the safety sleeve.

The safety sleeve preferably comes directly into contact with the material of the neck, that is to say the glass of the bottle when the container is a bottle of wine or spirits.

The security sleeve is arranged in such a way that, after its retraction, any attempt to fraudulently extract the sleeve in place visibly alters the sleeve and / or the information that it conveys and / or the security element that he wears. The safety sleeve is preferably put in place at the earliest in the production line. Thus, attempts at adulteration and counterfeiting before labeling can be more easily avoided. The safety element or elements present on the safety sleeve may have a so-called first, second or third level security feature. By "first level security" is meant a security element 10 visible to the naked eye, in daylight or artificial light, without the use of a particular device. These first-level security elements may be first-level elements with an optically variable effect, such as, for example, interferential platelet particles, magnetic or otherwise, liquid and / or oriented and / or photonic crystals, a holographic element or a network. lenses in combination with an underlying pattern. "Second-level security" means a safety element that is always visible to the naked eye, but only with a relatively simple device, such as a lamp emitting in the ultraviolet (UV) or infrared (IR) or a magnifying glass or decoder tool type optical filter or a polarizing filter. These second-level security elements are for example luminescent, that is to say have a specific emission in the visible under the illumination of a Wood lamp emitting in the UV for example at a wavelength of 365. nm. These second level elements can also be anti stokes elements, that is to say have a specific emission in the visible under the illumination of an IR pointer for example at a wavelength of 980 nm.

Second-level security is also understood to mean security that can be revealed by heat and / or friction. By "third-level security", it is necessary to understand a security element requiring for its detection a dedicated detection device. These security elements are for example capable of generating a specific signal when they are subjected, simultaneously or not, 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 element. These security elements comprise, for example, tracers or materials in the form of active materials, particles or fibers capable of generating a specific signal when these tracers are subjected to a mechanical, thermal, optronic, electrical stress. , magnetic or electromagnetic.

The security element or elements of the sleeve may be in the form of an impression, a wire, a flat band, a foil or a patch, being affixed to the inner or outer face of the sleeve. muff. The security element (s) of the sleeve may also be integrated into the mass of the polymer casing of the heat-shrinkable sleeve.

The security element or elements may in particular be printed on the inside of the security sleeve in contact with the neck of the container, in particular when the sleeve is obtained from a folded film on itself followed by a meeting two free edges. This film, before folding, can be printed by well known printing processes, such as gravure, screen printing, flexography or offset or inkjet. In a preferred embodiment, the film is printed with first, second and / or third level security inks in a portion of the sleeve that will remain visible after retraction of the sleeve on the container to be protected. The security sleeve preferably comprises security prints which are made in such a way that they remain visible and / or detectable after retraction of the sleeve onto the container, relying on anamorphosis techniques. The at least one first-level security element present on the security sleeve, in particular its lower part, may be elements with an optically variable effect, such as, for example, interferential platelet particles, magnetic or otherwise, liquid and / or oriented crystals. and / or photonics, a holographic element or a lens array in combination with an underlying pattern. The second level safety element or elements present on the safety sleeve, in particular its lower part, may be elements invisible to the naked eye under daylighting but visible under particular wavelength lighting. The safety sleeve may also comprise thermochromic elements, in particular liquid crystals and / or pigments and / or thermochromic dyes, which may change appearance at at least one predefined temperature. The container may then include 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 contents. . The appearance of the thermochromic elements, for example their coloring 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 temperature of change of appearance of the thermochromic elements. The security sleeve may also include an RFID device comprising an integrated circuit, with or without an integrated battery, with or without a microprocessor, with or without a sensor, for example for recording the temperature. The safety sleeve may comprise the following safety elements, alone or in combination: dyes and / or luminescent pigments and / or interferential pigments and / or liquid crystal pigments, in particular 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, especially in printed form or mixed with a constituent material of the sleeve envelope, 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, goniochromatic or holographic, a layer with variable optical effect base of interferential pigments or of liquid crystals, particles or agglomerates of particles of pigments or dyes of F11-LITE type, visible or non-visible, in particular luminescent, security fibers, in particular metallic, magnetic fibers (with magnetism soft and / or hard), or absorbent, or excitable to ultraviolet, visible or infrared, and in particular the near infrared (NIR), an automatically readable security having specific and measurable luminescence characteristics (e.g. fluorescence, phosphorescence), light absorption (eg ultraviolet, visible or infrared), Raman activity, magnetism, microwave interaction, RF interaction, X-ray interaction or electrical conductivity. The security sleeve may comprise at least one visible authentication element, such as, for example, a holographic foil, OVI type variable optical effect security prints, or authenticatable recognition elements dispersed in the material of the sleeve. The security sleeve may also comprise 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 unidirectional bar code in two. dimensions, EAN128 barcode type, or two-dimensional bidirectional barcode Datamatrix type or alphanumeric code written in clear. This code may or may not be encrypted. This identifier or code may be marked by any means and preferably by means of a visible iridescent ink or an invisible ink containing, for example, UV luminescent pigments, or particles visible when excited by radiation whose lengths The waves belong to the visible as described in documents EP 1 307 520 and EP 1 864 113, thereby realizing a tracking and traceability function as well as an authentication function. The sleeve can also comprise at least one visible two-dimensional code 25 type "quick response" (QR) or Datamatrix, for addressing, via a communicating device such as a phone (such as Smartphone for example) a website of producer or the certifying body through which any actor in the chain including the consumer may collect information on the content and carry out a verification of the identifier on his bottle.

The security sleeve may also have, especially at the level of the security element 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 sleeve has at the level of the unit identification code and / or code one or two dimensions, a sufficient contrast to allow its automatic reading. This contrast can be provided by a localized printing or over the entire surface, preferably on the inner face of the sleeve in contact with the neck opposite the code. This contrast can be brought in particular by an opaque printing having a different color from that used for marking. The casing of the sleeve can be made of one of the following plastics: PVC, HR PVC, PET, PETG, PS, OPS (oriented polystyrene), OPP (oriented polypropylene), TPEG, TPE S, PLA (polylactide acid) ), EPS (expanded PS) .... Preferably, one chooses a material and a thickness which brings a strength to the cut so that the sleeve is not cut or sheared during the usual handling of the container.

The safety sleeve may have on its inner or outer surface a primer or varnish or an adhesive, for example hot-activatable allowing increased adhesion between the safety sleeve and the neck and / or between the safety sleeve and a capsule. possible over-plugging. The security element (s) of the sleeve may be located on the inner face of the sleeve, that is to say the face which is in contact with the container, in order to be protected from wear or deterioration and to avoid the possibility of accessing it during attempts to falsify. The sleeve is then preferably made of a transparent material, so that such security elements are visible or optically detectable through the material of the sleeve.

In a variant, at least one security element of the sleeve, and in particular a unit identification code, is located on the outer face of the sleeve; indeed, any personalized information that will be read with a dedicated reader can be marked on the sleeve by printing or engraving, after the retraction operation thereof. The sleeve, before heat shrinking, preferably has a cylindrical or conical shape. The length of the sleeve may be between 1 and 8 cm, preferably between 2 and 4 cm, for example equal to about 3 cm. The thickness of the sleeve may be between 40 and 100 before retraction.

According to another of its aspects, the invention also relates to the heat-shrinkable safety sleeve for implementing the method according to the invention. The invention will be better understood on reading the following detailed description of non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. in elevation, schematically and with a partial longitudinal half section, a container secured with a safety sleeve according to the invention, - Figure 2 is a view similar to Figure 1, a variant of FIG. 3 is a half-view in elevation of another variant, FIG. 4 illustrates the possibility of locating a security element on the inner face of the sleeve, FIG. 5 is a diagrammatic representation of FIG. partially a masking layer, and - Figure 6 illustrates the establishment of an overcap on the closure member and the safety sleeve. In the appended drawing, the actual proportions of the various constituent elements or their spacings have not always been respected, for the sake of clarity. On the other hand, some elements may not have been represented in contact with each other while in practice. The containers shown in Figures 1 to 3 are bottles and contain a liquid, for example wine. Each container comprises, according to the invention, a safety sleeve 20 closely surrounding the neck 11, under the neck 12 and the ring 13.

In all the illustrated examples, the 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 12. In the example of FIG. 1, the bottle is closed by means of a closure member constituted by a screw cap 30. Such a cap known in itself is for example formed directly on the bottle and comprises in the lower part a tubular skirt 31 and in the upper part the plug 32 to unscrew, both being connected by a weakened zone 33 intended to break during opening.

3021637 12 The bottle has a screw thread 15 whose shape is matched by the cap 32. The latter houses a seal 36 compressed by the cap 32 against the upper edge of the neck 12. The screw cap 30 is preferably made of metal, for example aluminum. The safety sleeve 20 is, in the example of Figure 1, of substantially conical shape. It comprises an envelope 27 of heat-shrinkable plastic material, preferably transparent, and at least one security element 50 carried by this envelope.

The safety sleeve 20 is partly covered by the tubular skirt 31, and protrudes from the lower edge thereof downwards by a distance d, for example between 3 and 70 mm, preferably between 10 and 30 mm. The security element 50 is for example, as illustrated in FIG. 4, carried by the internal face 28 of the envelope 27.

The security element (s) 50 of the security sleeve 20 are preferably optically variable first-level security elements, the invention not being limited to a particular type of security element. Alternatively, or additionally, the security sleeve 20 includes a security element in the form of a second-level security print, invisible in daylight but visible only under a wavelength of the UV, previously printed on the inner side of the sleeve film before folding during manufacture, and a security element in the form of a tracer-based third-level security printing, detectable in the IR only with a dedicated reader, also printed on the inside of the film of the sleeve before folding.

The identification and / or authentication and / or traceability information carried by the heat-shrinkable sleeve may be printed on the inner face of the safety sleeve, in Indigo for example, with a visible or invisible ink having a specific response in luminescence, such as an ink that absorbs in the infrared for example. In addition, this printing can be masked with a blackout type OVI (Optical Variable Kik) under daylight. The information is made visible under specific lighting, such as under IR light, for example. The excited ink then passes through the blackout layer to become visible.

The identification and / or authentication and / or traceability information may be personalized to the direct or indirect printing means and / or the laser engraving means through the security sleeve on a previously deposited layer. internal side of the safety sleeve and / or in the thickness of the safety sleeve, this layer posting pigments laser marking or being metallized and de-metallized by the laser. The security sleeve can be used to convey information storage means such as a chip, a magnetic strip and / or an optical memory. For example, a blackout layer having security elements for authentication purposes may be printed / deposited on the inside of the security sleeve for concealing an RFID chip and without an antenna. The security element may comprise a code that is found elsewhere on or in the container, for example in the inner part of the closure member, so that the content can be authenticated once the container is open. The occulted code can also serve as a key to access a database which when consulted by means of this code, returns a second code which is written elsewhere on or in the container. The 2file code received from the database can thus be compared to a 2nd code written on the container to authenticate the content. The security sleeve 20 may further comprise a first level security element in the form of a variable optical effect printing of the OVI type, visible to the naked eye and previously printed on the outer face of the film of the sleeve before folding. . As mentioned above, the security sleeve 20 may comprise a unit identification code enabling a container tracking function, and is composed of, for example, 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 retraction on the container, the printing providing sufficient contrast on the printing background of the sleeve 20 to allow its automatic reading. The film of the sleeve 20 may also be printed with an opaque and colored printing background and with inscriptions in the name of the castle.

The security element 50 has been shown in FIGS. 1 to 3 with a substantially rectangular contour, but the invention is in no way limited to a particular form of security element. The variant of FIG. 2 differs from the example of FIG. 1 in that the sleeve 20 is not covered by the closure member 30, the latter being no longer a screw cap with a tubular skirt 31 but a tamper evident screw cap 39. The spacing m between the lower edge of the cap 30 and the upper edge of the sleeve 20 is for example between 3 and 30 mm, preferably between 5 and 10 mm. In this example, the safety sleeve is located under the ring 13 of the neck 11, on which the tamper-evident ring 39 is engaged. In the example of FIG. 3, the closure member 30 is constituted by a capsule crimped, and no longer by a screw cap. Such a capsule, known per se, comprises a portion crimped on the neck 12, preferably molded of plastic material, having a screw thread, the neck of the bottle being deprived of it, and a removable cap screwed onto this fixed part, may comprise an inner portion of plastic material, sealing and for screwing, and a metal outer portion formed with a tamper-proof ring at its base. The safety sleeve 20 is not covered by the capsule and extends over a substantially cylindrical portion of the neck, itself having a cylindrical shape.

The spacing m between the capsule 30 and the sleeve 20 may be in the same range of values as that given above. The safety sleeve 20 may have, as more particularly illustrated in Figure 5, a hidden information 55, covered by a masking layer 56, for example consisting of an opaque coating to be scratched.

For example, it is possible to print a scratch-off ink on the outside of the security sleeve 20, which will be scraped by the consumer to visualize underlying identification and / or authentication and / or traceability information. The container may comprise, as shown in Figure 6, an overcap 70, for example pressed tin.

In this case, it is preferable that the safety sleeve 20 remains at least partially visible, as illustrated, and that the security element 50 remains visible.

Identification and / or authentication and / or traceability information may be personalized by means of direct or indirect printing and / or laser engraving means, through the security sleeve on a layer at previously deposited on the inner side of the safety sleeve and / or in the thickness of the safety sleeve, this layer comprising pigments that can be laser marked or metallized and de-metallized by the laser. It may be interesting to make the safety sleeve with means to highlight an attempt to detach, especially from a fraudster who cut the sleeve and seek to remove and re-stick.

One possibility to create an interface layer for information on a detachment attempt may be to print the inner face of the sleeve with a pattern that appears on the container in case of detachment, for example the pattern "VOID". For example, a first composition, especially an ink, is printed or otherwise applied in the form of a first layer which is a text or pattern, consisting of a solid area with text areas or a pattern in reserve, then we come to print or apply differently in the second pass with a second composition, including an ink, a text or pattern corresponding to the previous reservations. The first and second compositions have different adhesion forces to the sleeve, the second composition being for example a "releasable" ink, with low internal cohesion 20 for example. The deposits of the first and second compositions may be coated with a re-activatable glue at very low temperature. Alternatively, the two compositions may consist of adhesives having different adhesion forces. Thus, when the sleeve is heat shrunk, one is left with a set assembly. Any attempt to open or detach the sleeve will then cause the appearance of a text or pattern by the separation between the first layer leaving with the sleeve, and the text remaining on the neck. It is also possible to provide the sleeve with a means making it possible to demonstrate a separation attempt as disclosed in publication WO96 / 02434, in particular in FIG. 8, which describes a heat-shrinkable sleeve with a layer with a low internal cohesion , for example comprising particles of aluminum, applied in the form of a pattern, for example "OPENED". In case of tearing of the sleeve, this layer separates into two parts, one of which remains on the container and the other with the sleeve. The pattern formed by this layer may be masked by a colored masking layer, and is not visible when the sleeve is in place on the neck.The invention is not limited to the examples which have just been described. In particular, it is possible to combine the particular features of the various illustrated examples with non-illustrated variants. The invention is in particular not limited to a particular type or form of container, or to a particular type of content. The expression "having one" should be understood as being synonymous with 10 "having at least one".
