Definitions

  • the invention relates to a container covered with a security envelope, capable of ensuring identification of fraudulent opening of such a container.
  • the applicant proposed in the document FR 2 754 375 a security envelope comprising a heat-shrinkable plastic sleeve equipped on its internal face with a holographic element and a tear strip passing over the holographic element in order to tear the holographic element when opening the envelope.
  • the holographic element is transferable to the wall of the facing container, so that any manipulation of the security envelope has the effect of automatically destroying the transferred holographic element.
  • the invention aims to provide a container covered with a security envelope having an increased level of security.
  • a container covered with a safety envelope surrounding the container the envelope comprising a sleeve and a safety strip secured to an internal face of said sleeve and comprising at least one weakening zone , the security strip being shaped so that it surrounds at least partly the container under a ring of the container and in the immediate vicinity of said ring, the security strip then creating a clamping zone of the container.
  • the safety strip when attempting to remove the sleeve, the safety strip will be very heavily stressed due to its arrangement just below the ring of the container and its tightening around the container. The weakened zone will consequently change state, leaving a visible trace of manipulation of the sleeve, in particular fraudulent manipulation of the sleeve.
  • container is meant a container comprising at least one body, a neck extending in the upper part of the body and a ring forming the open end of the container and itself extending the neck.
  • the ring can take different shapes and thus be flat, square... In all cases, the ring forms a shoulder with the collar at the level of the junction between the ring and the collar.
  • the ring is like this also called “carnette ring”, the carnette designating the raised ring of the ring partly forming said shoulder with the collar.
  • the weakening zone forms a break zone of the safety strip.
  • the weakened zone is thus formed by a cutout in the safety strip.
  • the safety strip is shaped like a crown.
  • At least part of the security strip is in contact with a flap of the container.
  • the security strip also includes at least one security sign.
  • the sleeve comprises at least one cutting line extending at least partly in a portion of the sleeve covering the safety strip.
  • the sleeve is shaped like a capsule.
  • the capsule is shaped like a truncated cone.
  • the envelope further comprises a washer protecting a cap of the container.
  • the capsule includes a circumferential chute, the washer resting on the chute.
  • the washer is arranged inside the sleeve between the chute and an internal face of an upper base of the capsule.
  • the washer is secured to the sleeve.
  • the security strip is in two parts.
  • the safety envelope according to the first embodiment of the invention comprises a sleeve 1 which is here made of heat-shrinkable plastic material and cut from a sheath made using a film in said material.
  • the sleeve 1 is for example made of a single-layer film.
  • the sleeve 1 is made of a multilayer heat-shrinkable material.
  • the sleeve 1 is for example based on polyester (like PET).
  • the sleeve 1 is here stretched to give it a single preferred direction of retraction.
  • the sleeve 1 is for example transparent, that is to say it allows objects to be clearly viewed through it.
  • Sleeve 1 is here transparent over its entire surface.
  • the sleeve 1 is equipped on its internal face (that is to say the face intended to come into contact with the container to be covered) with a safety strip 2.
  • the safety strip 2 extends here substantially over the entire circumference of the sleeve 1. When the sleeve is placed on a container 3, such as a bottle, the safety strip 2 thus extends substantially horizontally.
  • the sleeve 1 is thus in place on the container 3 by heat shrinkage. Sleeve 1 is therefore not self-adhesive.
  • the sleeve 1 is made of a heat-shrinkable material allowing control of the clamping force exerted by the sleeve 1 on the container 3. This makes it possible to optimize the adhesion of the sleeve 1 to the container 3 and thus to increase its resistance to removal and increase the safety of the container 3.
  • the safety band 2 then surrounds the container 3 under a ring 4 of the container 3 and in the immediate vicinity of said ring 4 once the safety envelope has been retracted on the container 3. More precisely, the band safety band 2 is arranged at the junction between the ring 4 and the neck 5 of the container 3. The safety band 2 is arranged immediately below the clip 6. In this way, the safety band 2 forms a tightening collar of the container 3 once the safety envelope has been retracted over container 3.
  • the safety band 2 exerts a tightening force but the sleeve 1 also by its retraction on the container 3.
  • the clamping force exerted on the container 3 at the level of the safety band 2 is defined by the safety band itself (dimensions, shape, material, etc. of the safety band 2) but also by the sleeve 1 (dimensions, shape, material, etc. of the sleeve 1) which surrounds the safety band 2. In this way, it is possible to play both on the safety band 2 and on the sleeve 1 to define the tightening at the level of the safety band 2 on the container 3.
  • the safety strip 2 is here cut from a flat material then attached and secured to the internal face of the sleeve 1 for example by gluing.
  • the safety strip 2 is cut from a multilayer flat material, including an adhesive layer directly allowing its bonding against the sleeve 1.
  • Safety strip 2 is made of plastic.
  • the safety strip 2 is for example based on a thermoplastic polymer.
  • the safety strip 2 is based on polyester.
  • the material of the security strip 2 is made of heat-shrinkable material. This facilitates the retraction of the safety envelope on the container 3.
  • the security strip 2 is shaped so as to have the same heat shrinkage characteristics as the sleeve 1.
  • This homogeneity between the safety strip 2 and the sleeve 1 allows the envelope to retract even on containers of very complex shapes, for example with containers whose diameter difference between a body and a neck can reach up to 80%. .
  • the security strip 2 is thus made of a heat-shrinkable material allowing control of the clamping force exerted by the security strip 2 on the container 3. This makes it possible to optimize the adhesion of the security strip to the container 3 and thus to increase its resistance to tearing and increase the safety of the container 3.
  • the material of the security strip 2 is not a heat-shrinkable material. This makes it easier to write additional safety signs directly on safety strip 2 (as we will see later).
  • the part of the sleeve 1 covering the safety strip 2 will be less subject to retraction than the rest of the sleeve 1, which will also facilitate the possible inscription of safety signs on this part of the sleeve 1.
  • the inscription of safety signs on the safety strip 2 and/or the sleeve 1 when the security strip 2 is made of heat-shrinkable material is of course also possible.
  • the security strip 2 is here transparent, that is to say it allows to clearly visualize objects through it.
  • Safety strip 2 is here transparent over its entire surface.
  • Safety band 2 typically includes several weakening zones.
  • the weakened zones are formed by cutouts 7 (shown here in dotted lines and only part of which is referenced) made in the safety strip 2 and only in the security strip 2.
  • cutouts 7 n do not reach the associated sleeve 1 which is therefore not weakened by these cutouts 7.
  • the cutouts 7 are provided at different locations on the security strip 2.
  • the cutouts 7 are shaped so as to each pass through the security strip 2 over its entire height.
  • the cutouts 7 are for example made by microperforation.
  • the safety strip 2 is shaped like a crown, that is to say that the clamping collar which it forms when the sleeve 1 is retracted onto the container 3 is not a simple ring.
  • the safety strip 2 is here shaped into a sinusoid over the entire circumference of the sleeve 1.
  • the safety strip 2 thus presents undulations which are regular here.
  • the safety strip 2 therefore forms waves over the entire circumference of the sleeve 1.
  • the security strip 2 is arranged on the sleeve 1 so that when the sleeve 1 is retracted on the container 3, the upper portions of the crown formed by the security strip 2 are in contact with the carnette 6 of the ring 4.
  • the sleeve 1 has two cutting lines 8, 9 (shown here in dotted lines). These cutting lines 8, 9 are produced for example by microperforation.
  • Said cutting lines 8, 9 are here created so as to extend parallel to each other and along a generatrix of the sleeve 1. When the sleeve 1 is placed on the container 3, the cutting lines 8 , 9 therefore extend substantially vertically. The lines cutting edge 8, 9 therefore have a section extending above the safety strip 2.
  • the cutting lines 8, 9 extend close to each other so as to define between them a removable portion 10 which is removed when the sleeve 1 is cut along the cutting lines 8, 9.
  • the security strip 2 is coated on its face in contact with the container 3 with a heat-reactivatable glue, also called heat-sensitive glue, so that when the sleeve 1 is heat-shrinked on the container 3, the security strip 2 becomes sticks to the wall of the container favoring greater subsequent stress on the safety strip 2 and in particular on its weakened zones when handling the container 3.
  • the glue covers totally or partially the face of the safety strip 2 depending on the targeted applications. For example, the glue covers only part of the weakened zones of the security strip 2, leading to heterogeneity on the security strip 2, facilitating the detection of fraudulent manipulation of the container 3.
  • the envelope is then slipped onto the container 3, here closed by a cap 11, then heated to cause heat shrinkage of the envelope (i.e. of the sleeve and here of the strip 2) on the neck 5 and the ring 4, covering at minus one edge of the plug 11. In this way, the envelope seals the plug 11 on the ring 4.
  • the security strip 2 is well arranged directly under the ring 4 so that the upper portions of the security strip 2 touch the ring 6.
  • the security strip 2 thus arranged therefore turns out to be very sensitive to the forces exerted on the ring 6 and/or the neck 5.
  • Security strip 2 therefore proves to be very effective in combating fraudulent manipulation of containers.
  • the envelope is identical to that of the first embodiment with the difference that the cutting lines 108, 109 of the sleeve 101 are arranged so as to extend substantially over the entire circumference of the sleeve 101 and no longer along a generatrix of the sleeve 101.
  • the cutting lines 108, 109 are here arranged so that one of the lines 108 lies on a part of the sleeve 101 not covering the security strip 102 and being located under the part of the sleeve 101 covering the security strip 102 and that the other of the lines 109 lies on the part of the sleeve 101 covering the safety strip 102.
  • the removable portion 110 defined by the two cutting lines 108, 109 straddles the part of the sleeve 101 covering the security strip 102.
  • the cutting lines 108, 109 are arranged so that the removable portion 110 is entirely arranged on the part of the sleeve 101 covering the safety strip 102.

  • the security signs 212, 213 can be in specific inks, have a three-dimensional effect, a color effect or even metallization, etc.
  • the security signs 212 carried by the security strip 202 are destroyed or at least damaged due to the separation of the security strip 202 into several elements . It therefore proves extremely difficult to recompose the security signs 212 when attempting to refit the security strip 202 on the sleeve 201, which further reinforces the security of the security envelope.
  • the security signs inscribed on the sleeve 201 and/or the security strip 202 include data which is specific to the container which the security envelope is intended to cover.

Description

L'invention concerne un récipient recouvert d'une enveloppe de sécurité, apte à assurer un repérage d'une ouverture frauduleuse d'un tel récipient.The invention relates to a container covered with a security envelope, capable of ensuring identification of fraudulent opening of such a container.

ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION

Dans certains domaines, il importe de prévoir sur des récipients des dispositifs garantissant leur non-ouverture, afin notamment d'éviter des contrefaçons du type délit de remplissage.In certain areas, it is important to provide devices on containers guaranteeing their non-opening, in particular to avoid counterfeits such as filling offenses.

Dans le domaine des bouteilles de vins et des spiritueux, il est ainsi connu de surmouler le bouchon à l'aide d'une capsule qui est embouties sur la bouteille ou qui est sertie sur la bouteille.In the field of wine and spirits bottles, it is thus known to overmold the stopper using a capsule which is stamped on the bottle or which is crimped on the bottle.

Toutefois, les contrefacteurs n'ont guère de difficultés à remplacer une capsule initiale par une autre de sorte que la simple capsule de sur-bouchage n'offre pas une protection suffisante.However, counterfeiters have little difficulty replacing an initial capsule with another so that the simple over-capping capsule does not offer sufficient protection.

Ainsi, afin d'essayer de renforcer la protection, il est à présent connu de recouvrir le goulot du récipient muni d'un bouchon d'un manchon en matière plastique thermorétractable. Pour ouvrir le récipient, il faut nécessairement enlever le manchon thermorétracté, ce qui impose de détruire celui-ci.Thus, in order to try to reinforce protection, it is now known to cover the neck of the container fitted with a cap with a heat-shrinkable plastic sleeve. To open the container, it is necessary to remove the heat-shrinkable sleeve, which requires destroying it.

Cependant, il a été constaté que certains contrefacteurs arrivaient malgré tout à remettre en place le manchon, ou à en remettre un neuf qu'ils thermoformaient directement sur le récipient. On a depuis proposé l'utilisation de manchons plus sophistiqués permettant d'augmenter la protection anti-ouverture.However, it was noted that some counterfeiters were still able to put the sleeve back in place, or to put a new one that they thermoformed directly onto the container. The use of more sophisticated sleeves has since been proposed to increase anti-opening protection.

Il est donc apparu un besoin de sophistiquer la protection anti-ouverture.A need therefore emerged to make the anti-opening protection more sophisticated.

A cet égard, la demanderesse a proposé dans le document FR 2 754 375 une enveloppe de sécurité comportant un manchon en matière plastique thermorétractable équipé sur sa face interne d'un élément holographique et d'une bande d'arrachage passant sur l'élément holographique afin de déchirer l'élément holographique lors de l'ouverture de l'enveloppe. L'élément holographique est transférable sur la paroi du récipient en regard, de sorte que toute manipulation de l'enveloppe de sécurité a pour effet de détruire automatiquement l'élément holographique transféré.In this regard, the applicant proposed in the document FR 2 754 375 a security envelope comprising a heat-shrinkable plastic sleeve equipped on its internal face with a holographic element and a tear strip passing over the holographic element in order to tear the holographic element when opening the envelope. The holographic element is transferable to the wall of the facing container, so that any manipulation of the security envelope has the effect of automatically destroying the transferred holographic element.

La demanderesse a également proposé dans le document FR 3 003 549 un manchon en matière plastique thermorétractable équipé sur sa face externe d'une bande de sécurité en matériau multicouche délaminable, le manchon présentant au moins une ligne de découpe passant sous la bande. Ainsi, lors d'une tentative de retrait du manchon, celui-ci va se déchirer selon la ligne de découpe, ce qui provoque la délamination au moins partielle de la bande, laissant ainsi une trace visible d'une manipulation frauduleuse de manchon.The applicant also proposed in the document FR 3 003 549 a sleeve made of heat-shrinkable plastic material equipped on its external face with a safety strip made of delaminable multilayer material, the sleeve having at least one cutting line passing under the strip. Thus, when attempting to remove the sleeve, it will tear along the cutting line, which causes at least partial delamination of the strip, thus leaving a visible trace of fraudulent handling of the sleeve.

Le document US 4 009 793 , qui montre un récipient selon le préambule de la revendication 1, propose d'entourer le bouchon d'une bouteille par une bande autoadhésive en matière thermorétractable associée à une bandelette en matière non thermorétractable.The document US 4,009,793 , which shows a container according to the preamble of claim 1, proposes surrounding the cap of a bottle with a self-adhesive strip of heat-shrinkable material associated with a strip of non-heat-shrinkable material.

Or cette solution présente de nombreuses limites et en particulier ne peut être appliquée que sur des zones de dimensions réduites et homogènes. Il s'avère en outre très simple de remplacer la bande par une nouvelle bande recouvrant les restes éventuels de la première bande.However, this solution has numerous limits and in particular can only be applied to areas of reduced and homogeneous dimensions. It is also very simple to replace the strip with a new strip covering any remains of the first strip.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention vise à proposer un récipient recouvert d'une enveloppe de sécurité présentant un niveau de sécurité accru.The invention aims to provide a container covered with a security envelope having an increased level of security.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

En vue de la réalisation de ce but, on propose un récipient recouvert d'une enveloppe de sécurité entourant le récipient, l'enveloppe comportant un manchon et une bande de sécurité solidarisée à une face interne dudit manchon et comportant au moins une zone de fragilisation, la bande de sécurité étant conformée de sorte qu'elle entoure au moins en partie le récipient sous une bague du récipient et à proximité immédiate de ladite bague, la bande de sécurité créant alors une zone de serrage du récipient.With a view to achieving this goal, we propose a container covered with a safety envelope surrounding the container, the envelope comprising a sleeve and a safety strip secured to an internal face of said sleeve and comprising at least one weakening zone , the security strip being shaped so that it surrounds at least partly the container under a ring of the container and in the immediate vicinity of said ring, the security strip then creating a clamping zone of the container.

On profite donc avantageusement de la jonction entre la bague et un col du récipient, jonction formant naturellement une zone de blocage et de rétention de par sa forme, pour placer la bande de sécurité à un endroit où elle sera nécessairement fortement sollicitée. En outre, la bande de sécurité conjointement au manchon exerce un effort de serrage sur le récipient assurant là-encore une forte sollicitation de la bande de sécurité lorsque l'on touche extérieurement le manchon.We therefore advantageously take advantage of the junction between the ring and a neck of the container, a junction naturally forming a blocking and retention zone due to its shape, to place the safety strip in a place where it will necessarily be heavily stressed. In addition, the safety strip together with the sleeve exerts a clamping force on the container, again ensuring strong stress on the security strip when the sleeve is touched externally.

Ainsi, lors d'une tentative de retrait du manchon, la bande de sécurité va être très fortement sollicitée du fait de son agencement juste en-dessous de la bague du récipient et de son serrage autour du récipient. La zone de fragilisation va en conséquence changer d'état laissant ainsi une trace visible d'une manipulation du manchon, en particulier d'une manipulation frauduleuse du manchon.Thus, when attempting to remove the sleeve, the safety strip will be very heavily stressed due to its arrangement just below the ring of the container and its tightening around the container. The weakened zone will consequently change state, leaving a visible trace of manipulation of the sleeve, in particular fraudulent manipulation of the sleeve.

Pour la présente demande, par « récipient » on entend un contenant comportant au moins un corps, un col prolongeant en partie supérieure le corps et une bague formant l'extrémité ouverte du récipient et prolongeant elle-même le col. La bague peut prendre différentes formes et être ainsi plate, carrée ... Dans tous les cas, la bague dessine un épaulement avec le col au niveau de la jonction entre la bague et le col. La bague est ainsi également nommée « bague à carnette », la carnette désignant l'anneau en relief de la bague formant en partie ledit épaulement avec le col.For the present application, by “container” is meant a container comprising at least one body, a neck extending in the upper part of the body and a ring forming the open end of the container and itself extending the neck. The ring can take different shapes and thus be flat, square... In all cases, the ring forms a shoulder with the collar at the level of the junction between the ring and the collar. The ring is like this also called “carnette ring”, the carnette designating the raised ring of the ring partly forming said shoulder with the collar.

De façon particulière, la zone de fragilisation forme une zone de rupture de la bande de sécurité.In particular, the weakening zone forms a break zone of the safety strip.

De façon particulière, la zone de fragilisation est ainsi formée par une découpe dans la bande de sécurité.In particular, the weakened zone is thus formed by a cutout in the safety strip.

De façon particulière, la bande de sécurité est conformée en couronne.In particular, the safety strip is shaped like a crown.

De façon particulière, au moins une partie de la bande de sécurité est au contact d'une carnette du récipient.In particular, at least part of the security strip is in contact with a flap of the container.

De façon particulière, la bande de sécurité comporte en outre au moins un signe de sécurité.In particular, the security strip also includes at least one security sign.

De façon particulière, le manchon comporte au moins une ligne de découpe s'étendant au moins en partie dans une portion du manchon recouvrant la bande de sécurité.In particular, the sleeve comprises at least one cutting line extending at least partly in a portion of the sleeve covering the safety strip.

De façon particulière, le manchon est conformé en une capsule.In particular, the sleeve is shaped like a capsule.

De façon particulière, la capsule est conformée en tronc de cône.In particular, the capsule is shaped like a truncated cone.

De façon particulière, l'enveloppe comporte en outre une rondelle de protection d'un bouchon du récipient.In particular, the envelope further comprises a washer protecting a cap of the container.

De façon particulière, la capsule comporte une goulotte circonférentielle, la rondelle reposant sur la goulotte.In particular, the capsule includes a circumferential chute, the washer resting on the chute.

De façon particulière, la rondelle est agencée à l'intérieur du manchon entre la goulotte et une face interne d'une base supérieure de la capsule.In particular, the washer is arranged inside the sleeve between the chute and an internal face of an upper base of the capsule.

De façon particulière la rondelle est solidarisée au manchon.In a particular way, the washer is secured to the sleeve.

De façon particulière, la bande de sécurité est en deux parties.In particular, the security strip is in two parts.

DESCRIPTION DETAILLEE DE MODES DE REALISATION DE L'INVENTIONDETAILED DESCRIPTION OF MODES OF CARRYING OUT THE INVENTION

En référence aux figures 1 à 4, l'enveloppe de sécurité selon le premier mode de réalisation de l'invention comporte un manchon 1 qui est ici en matière plastique thermorétractable et découpé dans une gaine réalisée à l'aide d'un film dans ladite matière. Le manchon 1 est par exemple réalisé dans un film monocouche. Alternativement, le manchon 1 est réalisé dans un matériau thermorétractable multicouche. Le manchon 1 est par exemple à base de polyester (comme du PET). Le manchon 1 est ici étiré pour lui donner une seule direction de rétraction privilégiée.With reference to figures 1 to 4 , the safety envelope according to the first embodiment of the invention comprises a sleeve 1 which is here made of heat-shrinkable plastic material and cut from a sheath made using a film in said material. The sleeve 1 is for example made of a single-layer film. Alternatively, the sleeve 1 is made of a multilayer heat-shrinkable material. The sleeve 1 is for example based on polyester (like PET). The sleeve 1 is here stretched to give it a single preferred direction of retraction.

Le manchon 1 est par exemple transparent c'est-à-dire qu'il permet de visualiser avec netteté des objets à travers lui. Le manchon 1 est ici transparent sur toute sa superficie.The sleeve 1 is for example transparent, that is to say it allows objects to be clearly viewed through it. Sleeve 1 is here transparent over its entire surface.

Le manchon 1 est équipé sur sa face interne (c'est-à-dire la face destinée à venir au contact du récipient à recouvrir) d'une bande de sécurité 2. La bande de sécurité 2 s'étend ici sensiblement sur toute la circonférence du manchon 1. Lorsque le manchon est mis en place sur un récipient 3, comme une bouteille, la bande de sécurité 2 s'étend ainsi sensiblement horizontalement.The sleeve 1 is equipped on its internal face (that is to say the face intended to come into contact with the container to be covered) with a safety strip 2. The safety strip 2 extends here substantially over the entire circumference of the sleeve 1. When the sleeve is placed on a container 3, such as a bottle, the safety strip 2 thus extends substantially horizontally.

Le manchon 1 est ainsi en place sur le récipient 3 par thermorétraction. Le manchon 1 n'est donc pas auto-adhésif.The sleeve 1 is thus in place on the container 3 by heat shrinkage. Sleeve 1 is therefore not self-adhesive.

Le manchon 1 est en un matériau thermorétractable permettant un contrôle de la force de serrage exercée par le manchon 1 sur le récipient 3. Ceci permet d'optimiser l'adhérence du manchon 1 au récipient 3 et ainsi d'augmenter sa résistance à l'arrachage et d'accroitre la sécurité du récipient 3.The sleeve 1 is made of a heat-shrinkable material allowing control of the clamping force exerted by the sleeve 1 on the container 3. This makes it possible to optimize the adhesion of the sleeve 1 to the container 3 and thus to increase its resistance to removal and increase the safety of the container 3.

La bande de sécurité 2 entoure alors le récipient 3 sous une bague 4 du récipient 3 et à proximité immédiate de ladite bague 4 une fois l'enveloppe de sécurité rétractée sur le récipient 3. Plus précisément, la bande de sécurité 2 est agencée au niveau de la jonction entre la bague 4 et le col 5 du récipient 3. La bande de sécurité 2 est agencée immédiatement dessous la carnette 6. De la sorte, la bande de sécurité 2 forme un collier de serrage du récipient 3 une fois l'enveloppe de sécurité rétractée sur le récipient 3.The safety band 2 then surrounds the container 3 under a ring 4 of the container 3 and in the immediate vicinity of said ring 4 once the safety envelope has been retracted on the container 3. More precisely, the band safety band 2 is arranged at the junction between the ring 4 and the neck 5 of the container 3. The safety band 2 is arranged immediately below the clip 6. In this way, the safety band 2 forms a tightening collar of the container 3 once the safety envelope has been retracted over container 3.

De façon avantageuse, on note que la bande de sécurité 2 exerce un effort de serrage mais le manchon 1 également de par sa rétraction sur le récipient 3. On peut ainsi jouer sur les efforts de serrage exercés respectivement par la bande de sécurité 2 et le manchon 1 et par exemple conformer bande de sécurité 2 et manchon 1 pour que la bande de sécurité 2 et le manchon 1 exercent des efforts de serrage différents sur le récipient 3 ou au contraire un même effort de serrage.Advantageously, we note that the safety band 2 exerts a tightening force but the sleeve 1 also by its retraction on the container 3. We can thus play on the tightening forces exerted respectively by the safety band 2 and the sleeve 1 and for example conform safety strip 2 and sleeve 1 so that the safety strip 2 and the sleeve 1 exert different clamping forces on the container 3 or on the contrary the same clamping force.

On note par ailleurs que l'effort de serrage exercé sur le récipient 3 au niveau de la bande de sécurité 2 est défini par la bande de sécurité elle-même (dimensions, forme, matériau ... de la bande de sécurité 2) mais également par le manchon 1 (dimensions, forme, matériau ... du manchon 1) qui entoure la bande de sécurité 2. De la sorte, il est possible de jouer à la fois sur la bande de sécurité 2 et sur le manchon 1 pour définir le serrage au niveau de la bande de sécurité 2 sur le récipient 3.We also note that the clamping force exerted on the container 3 at the level of the safety band 2 is defined by the safety band itself (dimensions, shape, material, etc. of the safety band 2) but also by the sleeve 1 (dimensions, shape, material, etc. of the sleeve 1) which surrounds the safety band 2. In this way, it is possible to play both on the safety band 2 and on the sleeve 1 to define the tightening at the level of the safety band 2 on the container 3.

La bande de sécurité 2 est ici découpée dans un matériau plat puis rapportée et solidarisée à la face interne du manchon 1 par exemple par collage. En variante, la bande de sécurité 2 est découpée dans un matériau plat multicouche, dont une couche adhésive permettant directement son collage contre le manchon 1.The safety strip 2 is here cut from a flat material then attached and secured to the internal face of the sleeve 1 for example by gluing. Alternatively, the safety strip 2 is cut from a multilayer flat material, including an adhesive layer directly allowing its bonding against the sleeve 1.

La bande de sécurité 2 est à base de matière plastique. La bande de sécurité 2 est par exemple à base d'un polymère thermoplastique. Typiquement, la bande de sécurité 2 est à base de polyester.Safety strip 2 is made of plastic. The safety strip 2 is for example based on a thermoplastic polymer. Typically, the safety strip 2 is based on polyester.

De façon particulière, le matériau de la bande de sécurité 2 est en matériau thermorétractable. Ceci facilite la rétraction de l'enveloppe de sécurité sur le récipient 3.In particular, the material of the security strip 2 is made of heat-shrinkable material. This facilitates the retraction of the safety envelope on the container 3.

De préférence, la bande de sécurité 2 est conformée de sorte à présenter les mêmes caractéristiques de thermorétraction que le manchon 1.Preferably, the security strip 2 is shaped so as to have the same heat shrinkage characteristics as the sleeve 1.

Cette homogénéité entre la bande de sécurité 2 et le manchon 1 autorise l'enveloppe à se rétracter même sur des récipients de formes très complexes par exemple avec des récipients dont une différence de diamètres entre un corps et un col peut atteindre jusqu'à 80 %.This homogeneity between the safety strip 2 and the sleeve 1 allows the envelope to retract even on containers of very complex shapes, for example with containers whose diameter difference between a body and a neck can reach up to 80%. .

La bande de sécurité 2 est ainsi en un matériau thermorétractable permettant un contrôle de la force de serrage exercée par la bande de sécurité 2 sur le récipient 3. Ceci permet d'optimiser l'adhérence de la bande de sécurité au récipient 3 et ainsi d'augmenter sa résistance à l'arrachage et d'accroître la sécurité du récipient 3.The security strip 2 is thus made of a heat-shrinkable material allowing control of the clamping force exerted by the security strip 2 on the container 3. This makes it possible to optimize the adhesion of the security strip to the container 3 and thus to increase its resistance to tearing and increase the safety of the container 3.

En variante le matériau de la bande de sécurité 2 n'est pas en un matériau thermorétractable. Ceci facilite l'inscription de signes de sécurité supplémentaires directement sur la bande de sécurité 2 (comme nous le verrons par la suite). De plus, la partie du manchon 1 recouvrant la bande de sécurité 2 sera moins soumise à la rétraction que le reste du manchon 1, ce qui facilitera également l'inscription éventuelle de signes de sécurité sur cette partie du manchon 1. L'inscription de signes de sécurité sur la bande de sécurité 2 et/ou le manchon 1 quand la bande de sécurité 2 est en matériau thermorétractable est bien entendu également possible.La bande de sécurité 2 est ici transparente c'est-à-dire qu'elle permet de visualiser avec netteté des objets à travers elle. La bande de sécurité 2 est ici transparente sur toute sa superficie.Alternatively, the material of the security strip 2 is not a heat-shrinkable material. This makes it easier to write additional safety signs directly on safety strip 2 (as we will see later). In addition, the part of the sleeve 1 covering the safety strip 2 will be less subject to retraction than the rest of the sleeve 1, which will also facilitate the possible inscription of safety signs on this part of the sleeve 1. The inscription of safety signs on the safety strip 2 and/or the sleeve 1 when the security strip 2 is made of heat-shrinkable material is of course also possible. The security strip 2 is here transparent, that is to say it allows to clearly visualize objects through it. Safety strip 2 is here transparent over its entire surface.

La bande de sécurité 2 comporte typiquement plusieurs zones de fragilisation. De façon particulière, les zones de fragilisation sont formées par des découpes 7 (représentées ici en pointillés et dont une partie seulement est référencée) pratiquées dans la bande de sécurité 2 et seulement dans la bande de sécurité 2. En effet, ces découpes 7 n'atteignent pas le manchon 1 associé qui n'est donc pas fragilisé par ces découpes 7.Safety band 2 typically includes several weakening zones. In particular, the weakened zones are formed by cutouts 7 (shown here in dotted lines and only part of which is referenced) made in the safety strip 2 and only in the security strip 2. In fact, these cutouts 7 n do not reach the associated sleeve 1 which is therefore not weakened by these cutouts 7.

Les découpes 7 sont ménagées à différents endroit de la bande de sécurité 2. Les découpes 7 sont conformées de sorte à ici traverser chacune la bande de sécurité 2 sur toute sa hauteur. Les découpes 7 sont par exemple faite par microperforation.The cutouts 7 are provided at different locations on the security strip 2. The cutouts 7 are shaped so as to each pass through the security strip 2 over its entire height. The cutouts 7 are for example made by microperforation.

De préférence, la bande de sécurité 2 est conformée en couronne c'est-à-dire que le collier de serrage qu'elle forme lorsque le manchon 1 est rétracté sur le récipient 3 n'est pas un simple anneau.Preferably, the safety strip 2 is shaped like a crown, that is to say that the clamping collar which it forms when the sleeve 1 is retracted onto the container 3 is not a simple ring.

La bande de sécurité 2 est ici conformée en une sinusoïde sur toute la circonférence du manchon 1. La bande de sécurité 2 présente ainsi des ondulations qui sont ici régulières. La bande de sécurité, 2 forme donc des vagues sur toute la circonférence du manchon 1.The safety strip 2 is here shaped into a sinusoid over the entire circumference of the sleeve 1. The safety strip 2 thus presents undulations which are regular here. The safety strip 2 therefore forms waves over the entire circumference of the sleeve 1.

De façon préférée, la bande de sécurité 2 est agencée sur le manchon 1 de sorte que lorsque le manchon 1 est rétracté sur le récipient 3, les portions hautes de la couronne formée par la bande de sécurité 2 sont au contact de la carnette 6 de la bague 4.Preferably, the security strip 2 is arranged on the sleeve 1 so that when the sleeve 1 is retracted on the container 3, the upper portions of the crown formed by the security strip 2 are in contact with the carnette 6 of the ring 4.

Par ailleurs, le manchon 1 comporte deux lignes de découpe 8, 9 (représentées ici en pointillés). Ces lignes de découpe 8, 9 sont réalisées par exemple par microperforation.Furthermore, the sleeve 1 has two cutting lines 8, 9 (shown here in dotted lines). These cutting lines 8, 9 are produced for example by microperforation.

Lesdites lignes de découpe 8, 9 sont ici créées de sorte à s'étendre parallèlement l'une à l'autre et selon une génératrice du manchon 1. Lorsque le manchon 1 est mis en place sur le récipient 3, les lignes de découpe 8, 9 s'étendent donc sensiblement verticalement. Les lignes de découpe 8, 9 présentent donc un tronçon s'étendant au-dessus de la bande de sécurité 2.Said cutting lines 8, 9 are here created so as to extend parallel to each other and along a generatrix of the sleeve 1. When the sleeve 1 is placed on the container 3, the cutting lines 8 , 9 therefore extend substantially vertically. The lines cutting edge 8, 9 therefore have a section extending above the safety strip 2.

Les lignes de découpe 8, 9 s'étendent à proximité l'une de l'autre de sorte à définir entre elles une portion amovible 10 qui est enlevée lorsque le manchon 1 est découpé selon les lignes de découpe 8, 9.The cutting lines 8, 9 extend close to each other so as to define between them a removable portion 10 which is removed when the sleeve 1 is cut along the cutting lines 8, 9.

En option, la bande de sécurité 2 est revêtue sur sa face en contact avec le récipient 3 d'une colle thermoréactivable, encore appelée colle thermosensible, de sorte que lorsque le manchon 1 est thermorétracté sur le récipient 3, la bande de sécurité 2 se colle à la paroi du récipient favorisant une sollicitation ultérieure plus importante de la bande de sécurité 2 et notamment de ses zones de fragilisation lors de la manipulation du récipient 3. La colle recouvre totalement ou en partie la face de la bande de sécurité 2 selon les applications visées. Par exemple, la colle ne recouvre qu'une partie seulement des zones de fragilisation de la bande de sécurité 2 entraînant une hétérogénéité sur la bande de sécurité 2 facilitant la détection d'une manipulation frauduleuse du récipient 3.Optionally, the security strip 2 is coated on its face in contact with the container 3 with a heat-reactivatable glue, also called heat-sensitive glue, so that when the sleeve 1 is heat-shrinked on the container 3, the security strip 2 becomes sticks to the wall of the container favoring greater subsequent stress on the safety strip 2 and in particular on its weakened zones when handling the container 3. The glue covers totally or partially the face of the safety strip 2 depending on the targeted applications. For example, the glue covers only part of the weakened zones of the security strip 2, leading to heterogeneity on the security strip 2, facilitating the detection of fraudulent manipulation of the container 3.

L'enveloppe est alors enfilée sur le récipient 3, ici fermé par un bouchon 11, puis chauffée pour provoquer la thermorétraction de l'enveloppe (i.e. du manchon et ici de la bande 2) sur le col 5 et la bague 4, recouvrant au moins un bord du bouchon 11. De la sorte, l'enveloppe scelle le bouchon 11 sur la bague 4.The envelope is then slipped onto the container 3, here closed by a cap 11, then heated to cause heat shrinkage of the envelope (i.e. of the sleeve and here of the strip 2) on the neck 5 and the ring 4, covering at minus one edge of the plug 11. In this way, the envelope seals the plug 11 on the ring 4.

Le résultat est alors visible à la figure 2.The result is then visible figure 2 .

On note que dans cette position, la bande de sécurité 2 est bien agencée directement sous la bague 4 de sorte que les portions hautes de la bande de sécurité 2 touchent la carnette 6. La bande de sécurité 2 ainsi agencée s'avère donc très sensible aux efforts exercés sur la bague 6 et/ou le col 5.Note that in this position, the security strip 2 is well arranged directly under the ring 4 so that the upper portions of the security strip 2 touch the ring 6. The security strip 2 thus arranged therefore turns out to be very sensitive to the forces exerted on the ring 6 and/or the neck 5.

Ainsi, si on force sur le manchon 1 pour le retirer frauduleusement du récipient 3 on exerce des efforts très importants sur le manchon 1 notamment au niveau de la zone du manchon 1 en contact avec la carnette 6 formant naturellement une zone de blocage et de rétention. Ceci va provoquer le déchirement de la bande de sécurité 2 au niveau de ses différentes zones de fragilisation. Ainsi, la bande de sécurité 2 se retrouve séparée en plusieurs éléments et il n'est plus possible de la recomposer, ses éléments constitutifs étant séparés et bloqués par le manchon 1 qui lui reste intact sur le récipient 3 (n'étant pas concerné par ces zones de fragilisation). La tentative de fraude s'avère donc bien visible comme illustré à figure 3.Thus, if we force the sleeve 1 to fraudulently remove it from the container 3, we exert very strong forces. important on the sleeve 1 in particular at the level of the area of the sleeve 1 in contact with the carnette 6 naturally forming a blocking and retention zone. This will cause the safety strip 2 to tear at its various weakened zones. Thus, the safety strip 2 finds itself separated into several elements and it is no longer possible to recompose it, its constituent elements being separated and blocked by the sleeve 1 which remains intact on the container 3 (not being affected by these areas of weakness). The attempted fraud is therefore clearly visible as illustrated in Figure 3 .

Si on arrive malgré tout à retirer le manchon 1 en continuant à tirer dessus, il ne s'avère plus possible de recomposer la bande de sécurité 2 de sorte qu'il est alors très difficile voire impossible de tenter de remettre en place le manchon 1 sur le récipient 3. On empêche ainsi toute manipulation frauduleuse du récipient 3.If we nevertheless manage to remove the sleeve 1 by continuing to pull on it, it no longer proves possible to recompose the safety strip 2 so that it is then very difficult or even impossible to try to put the sleeve 1 back in place. on the container 3. This prevents any fraudulent manipulation of the container 3.

Par ailleurs, comme illustré à la figure 4, si le manchon 1 est déchiré selon les lignes de découpe 8, 9 pour retirer la portion amovible 10, ceci provoque de nombreuses contraintes sur la bande de sécurité 2 et en particulier sur les différentes zones de fragilisation notamment au moment du déchirement de la partie du manchon 1 recouvrant la bande de sécurité 2. Ceci provoque le déchirement de la bande de sécurité 2 au niveau de ses zones de fragilisation : la bande de sécurité 2 se retrouve donc séparée en plusieurs éléments et il n'est plus possible de la recomposer, ses éléments constitutifs étant séparés.Furthermore, as illustrated in Figure 4 , if the sleeve 1 is torn along the cutting lines 8, 9 to remove the removable portion 10, this causes numerous stresses on the safety strip 2 and in particular on the different zones of weakening, particularly when the part is torn of the sleeve 1 covering the safety strip 2. This causes the tearing of the security strip 2 at its weakened zones: the security strip 2 therefore finds itself separated into several elements and it is no longer possible to recompose it , its constituent elements being separated.

Encore une fois, il est alors très difficile voire impossible de tenter de remettre en place le manchon 1 sur le récipient 3. On empêche ainsi toute manipulation frauduleuse du récipient 3.Once again, it is then very difficult or even impossible to try to put the sleeve 1 back in place on the container 3. This prevents any fraudulent manipulation of the container 3.

La bande de sécurité 2 s'avère donc très efficace pour lutter contre des manipulations frauduleuses de récipients. Dans un deuxième mode de réalisation illustré à la figure 5, l'enveloppe est identique à celle du premier mode de réalisation à la différence que les lignes de découpe 108, 109 du manchon 101 sont agencées de sorte à s'étendre sensiblement sur toute la circonférence du manchon 101 et non plus selon une génératrice du manchon 101.Security strip 2 therefore proves to be very effective in combating fraudulent manipulation of containers. In a second embodiment illustrated in figure 5 , the envelope is identical to that of the first embodiment with the difference that the cutting lines 108, 109 of the sleeve 101 are arranged so as to extend substantially over the entire circumference of the sleeve 101 and no longer along a generatrix of the sleeve 101.

Les lignes de découpe 108, 109 sont ici agencées de sorte qu'une des lignes 108 s'entende sur une partie du manchon 101 ne recouvrant pas la bande de sécurité 102 et se situant sous la partie du manchon 101 recouvrant la bande de sécurité 102 et que l'autre des lignes 109 s'entende sur la partie du manchon 101 recouvrant la bande de sécurité 102. Ainsi, la portion amovible 110 définit par les deux lignes de découpe 108, 109 se trouve à cheval sur la partie du manchon 101 recouvrant la bande de sécurité 102.The cutting lines 108, 109 are here arranged so that one of the lines 108 lies on a part of the sleeve 101 not covering the security strip 102 and being located under the part of the sleeve 101 covering the security strip 102 and that the other of the lines 109 lies on the part of the sleeve 101 covering the safety strip 102. Thus, the removable portion 110 defined by the two cutting lines 108, 109 straddles the part of the sleeve 101 covering the security strip 102.

En variante, les lignes de découpe 108, 109 sont agencées de sorte que la portion amovible 110 se trouve entièrement agencée sur la partie du manchon 101 recouvrant la bande de sécurité 102.Alternatively, the cutting lines 108, 109 are arranged so that the removable portion 110 is entirely arranged on the part of the sleeve 101 covering the safety strip 102.

Selon un troisième mode de réalisation illustré à la figure 6, l'enveloppe est identique à celle du premier mode de réalisation à la différence que la bande de sécurité 202 comporte en outre des signes de sécurité 212 supplémentaires (dont une partie seulement est référencée ici) .According to a third embodiment illustrated in Figure 6 , the envelope is identical to that of the first embodiment with the difference that the security strip 202 also includes additional security signs 212 (only part of which is referenced here).

Le manchon 201 comporte également lui-même des signes de sécurité 213 additionnels.The sleeve 201 itself also includes additional safety signs 213.

Les signes de sécurité 212, 213 du manchon 201 et de la bande de sécurité 202 peuvent comprendre par exemple un code numérique, un code-barres, un code de type QR (code-barres à deux dimensions), un numéro, un élément holographique, un logo, un élément en relief ... Les signes de sécurité 212, 213 peuvent être dans des encres spécifiques, présenter un effet en trois dimensions, un effet de couleur ou encore de métallisation ...The security signs 212, 213 of the sleeve 201 and the security strip 202 may include for example a digital code, a bar code, a QR type code (two-dimensional bar code), a number, a holographic element , a logo, an embossed element... The security signs 212, 213 can be in specific inks, have a three-dimensional effect, a color effect or even metallization, etc.

Lorsque la bande de sécurité 202 se déchire au niveau de ses zones de fragilisation, les signes de sécurité 212 portés par la bande de sécurité 202 sont détruits ou à tout le moins détériorés du fait de la séparation de la bande de sécurité 202 en plusieurs éléments. Il s'avère donc extrêmement difficile de recomposer les signes de sécurité 212 en tentant de remettre en place la bande de sécurité 202 sur le manchon 201, ce qui renforce encore davantage la sécurité de l'enveloppe de sécurité.When the security strip 202 tears at its weakened zones, the security signs 212 carried by the security strip 202 are destroyed or at least damaged due to the separation of the security strip 202 into several elements . It therefore proves extremely difficult to recompose the security signs 212 when attempting to refit the security strip 202 on the sleeve 201, which further reinforces the security of the security envelope.

De préférence, les signes de sécurité inscrits sur le manchon 201 et/ou la bande de sécurité 202 comprennent des données qui sont spécifiques au récipient que l'enveloppe de sécurité est destinée à recouvrir. Par exemple, au moins l'un des signes de sécurité est établi à partir d'un code d'identification unique qui est propre au récipient à recouvrir. Le signe de sécurité varie ainsi d'un récipient à un autre ce qui renforce la sécurité de l'enveloppe.Preferably, the security signs inscribed on the sleeve 201 and/or the security strip 202 include data which is specific to the container which the security envelope is intended to cover. For example, at least one of the security signs is established from a unique identification code which is specific to the container to be covered. The security sign thus varies from one container to another, which reinforces the security of the envelope.

Les différents signes de sécurité 212, 213 sont rapportés par tout moyen sur leurs supports respectifs. Ils peuvent par exemple être imprimés sur la bande de sécurité 202 ou le manchon 201.The different security signs 212, 213 are reported by any means on their respective supports. They can for example be printed on the security strip 202 or the sleeve 201.

En variante ou en complément, les signes de sécurité 212, 213 comportent des impressions transférables sur la paroi du récipient. Ces signes sont par exemple imprimés sur la face interne du manchon 201 et/ou de la bande de sécurité 202 et leurs contours sont microperforés. La surface des impressions est de préférence revêtue de colle thermoréactivable, encore appelée colle thermosensible, de sorte que lorsque le manchon 201 est thermorétracté, la partie du manchon 201 ou de la bande de sécurité 202 qui porte les impressions se colle à la paroi du récipient. La surface des impressions transférables peut toutefois être revêtue de n'importe quel type de matériau adhésif permettant l'adhérence des impressions à la paroi du récipient. Le matériau adhésif peut ainsi également être une colle à froid.Alternatively or in addition, the safety signs 212, 213 include transferable impressions on the wall of the container. These signs are for example printed on the internal face of the sleeve 201 and/or the safety strip 202 and their contours are microperforated. The surface of the prints is preferably coated with heat-reactivatable glue, also called heat-sensitive glue, so that when the sleeve 201 is heat shrunk, the part of the sleeve 201 or the security strip 202 which carries the prints sticks to the wall of the container. The surface of the transferable prints can, however, be coated with any type of adhesive material allowing the prints to adhere to the wall of the container. The adhesive material can thus also be a cold glue.

Ainsi, lorsqu'on enlève le manchon 201, les impressions restent en place sur la paroi du récipient et marquent le récipient lui-même : le signe de sécurité est ainsi resté invisible de l'extérieur jusqu'à la rupture du manchon.Thus, when the sleeve 201 is removed, the prints remain in place on the wall of the container and mark the container itself: the security sign thus remained invisible from the outside until the sleeve broke.

L'invention se prête donc à de nombreuses variantes. Ainsi en référence aux figures 7a à 7c, la bande de sécurité peut être conformée différemment qu'en sinusoïde comme dans le premier mode de réalisation. En place de vaguelettes, la bande de sécurité peut ainsi comporter une succession d'éléments géométriques reliés entre eux par des parties linéaires. Par exemple, comme illustré à la figure 7a, la bande de sécurité 302a est conformée de sorte à être formée par des losanges 314 reliés entre eux par des parties plates 315.The invention therefore lends itself to numerous variations. Thus with reference to figures 7a to 7c , the safety strip can be shaped differently than in a sinusoid as in the first embodiment. In place of waves, the safety strip can thus comprise a succession of geometric elements linked together by linear parts. For example, as illustrated in figure 7a , the safety strip 302a is shaped so as to be formed by diamonds 314 interconnected by flat parts 315.

La bande de sécurité 302c peut également former un zigzag comme proposé à la figure 7c.The security strip 302c can also form a zigzag as proposed in the figure 7c .

Il est également possible que la bande de sécurité 302b ne forme pas une couronne mais un simple anneau comme proposé à la figure 7b.It is also possible that the security band 302b does not form a crown but a simple ring as proposed in the figure 7b .

On préférera cependant avoir une forme de couronne plus élaborée pour la bande de sécurité afin de créer un repère visuel plus fort. Ceci favorise en outre la fragilisation de la bande de sécurité et son inclinaison à se décomposer.However, we would prefer to have a more elaborate crown shape for the safety strip in order to create a stronger visual cue. This further promotes the weakening of the security strip and its inclination to decompose.

De façon avantageuse, il est ainsi possible d'adapter la forme de la bande de sécurité selon les besoins et envie d'un client. On peut aussi personnaliser la couleur de la bande de sécurité. On peut aussi personnaliser les signes de sécurité éventuellement présents sur la bande de sécurité.Advantageously, it is thus possible to adapt the shape of the safety strip according to the needs and desires of a customer. You can also customize the color of the safety strip. Can also personalize any safety signs that may be present on the safety strip.

Ceci rend l'enveloppe particulièrement personnalisable et adaptable aux besoins de chaque client.This makes the envelope particularly customizable and adaptable to the needs of each customer.

En référence à la figure 8, selon un quatrième mode de réalisation de l'invention, en place d'être de forme tubulaire comme dans les autres modes de réalisation, le manchon 401 est conformé en une capsule.In reference to the figure 8 , according to a fourth embodiment of the invention, instead of being of tubular shape as in the other embodiments, the sleeve 401 is shaped like a capsule.

La capsule a typiquement la forme d'un tronc de cône avec une base supérieure 416 fermée destinée à venir recouvrir entièrement l'extrémité supérieure du récipient 403 et une jupe 417 s'étendant à partir de cette base supérieure 416 et destinée à entourer la bague 404 et une partie du col 405. En variante, la capsule est cylindrique.The capsule typically has the shape of a truncated cone with a closed upper base 416 intended to completely cover the upper end of the container 403 and a skirt 417 extending from this upper base 416 and intended to surround the ring 404 and part of the neck 405. Alternatively, the capsule is cylindrical.

L'enveloppe est alors enfilée sur le récipient 403, ici fermé par un bouchon 411, puis chauffée pour provoquer la thermorétraction du manchon 401 sur le col 405 et la bague 404 du récipient 403, recouvrant tout le bouchon 411. De la sorte, l'enveloppe scelle le bouchon 411 sur la bague 404.The envelope is then slipped onto the container 403, here closed by a cap 411, then heated to cause heat shrinkage of the sleeve 401 on the neck 405 and the ring 404 of the container 403, covering the entire cap 411. In this way, the The envelope seals the plug 411 on the ring 404.

Bien entendu, même avec cette forme d'enveloppe, la bande de sécurité 402 entoure toujours le récipient 403 immédiatement sous la bague 404 du récipient 403 de sorte à créer un collier de serrage du récipient 403 au niveau de la carnette 406.Of course, even with this shape of envelope, the safety band 402 always surrounds the container 403 immediately under the ring 404 of the container 403 so as to create a clamping collar of the container 403 at the level of the carnette 406.

En référence à la figure 9, selon une variante de réalisation du quatrième mode de réalisation, le manchon 501 comporte au niveau de la partie supérieure de sa jupe 516 une goulotte 518. Cette goulotte 518 s'étend ici sensiblement sur toute la circonférence de la jupe 516. Il y a donc de par cette goulotte 518 circonférentielle, un resserrage de la jupe 516 à ce niveau. Pour une question de compréhension, les dimensions de la goulotte 518 ont volontairement été agrandies ici.In reference to the Figure 9 , according to a variant of the fourth embodiment, the sleeve 501 comprises at the level of the upper part of its skirt 516 a chute 518. This chute 518 extends here substantially over the entire circumference of the skirt 516. There is therefore by this circumferential chute 518, a tightening of the skirt 516 at this level. For the sake of understanding, the dimensions of chute 518 have been deliberately enlarged here.

L'enveloppe comporte en outre une rondelle 519 de protection qui est agencée à l'intérieur du manchon 501 entre la goulotte 518 et une face interne de la base supérieure 516. La rondelle 519 s'appuie ainsi sur la goulotte 518 ce qui permet que la rondelle 519 demeure en place dans l'enveloppe lors de la manipulation de l'enveloppe. En particulier, la rondelle 519 est liée à l'enveloppe en étant agencée de cette manière. En variante la rondelle 519 est en outre fixée à l'enveloppe par exemple par collage.The envelope further comprises a protective washer 519 which is arranged inside the sleeve 501 between the chute 518 and an internal face of the upper base 516. The washer 519 thus rests on the chute 518 which allows that the washer 519 remains in place in the envelope when handling the envelope. In particular, the washer 519 is linked to the casing by being arranged in this manner. Alternatively, the washer 519 is also fixed to the envelope, for example by gluing.

Bien entendu, la rondelle 519 est de dimensions et dans un matériau adapté à limiter un risque de percement par un objet extérieur tel qu'une seringue. La rondelle 519 est par exemple une plaque en matériau métallique.Of course, the washer 519 is of dimensions and in a material adapted to limit a risk of piercing by an external object such as a syringe. The washer 519 is for example a plate made of metallic material.

De la sorte, lorsque l'on place l'enveloppe sur le col d'un récipient, la rondelle 519 vient naturellement se placer sur ou légèrement au-dessus du bouchon.In this way, when the envelope is placed on the neck of a container, the washer 519 naturally comes to be placed on or slightly above the cap.

On note que la rondelle 519 s'étend ainsi à travers le manchon 501 et à l'intérieur du manchon. La rondelle 519 obstrue ici la partie supérieure du manchon 501. La rondelle 519 est ici cylindrique et présente un diamètre sensiblement égal à celui de la base supérieure 516.Note that the washer 519 thus extends through the sleeve 501 and inside the sleeve. The washer 519 here obstructs the upper part of the sleeve 501. The washer 519 is here cylindrical and has a diameter substantially equal to that of the upper base 516.

L'enveloppe est alors chauffée pour provoquer la thermorétraction du manchon 501 sur le col et la bague, recouvrant tout le bouchon. De la sorte, l'enveloppe scelle le bouchon sur la bague et par la même occasion scelle la rondelle 519 au bouchon et à la bague.The envelope is then heated to cause heat shrinkage of the sleeve 501 on the neck and the ring, covering the entire cap. In this way, the envelope seals the cap on the ring and at the same time seals the washer 519 to the cap and to the ring.

Ceci permet de sécuriser encore davantage le récipient. En effet, la rondelle 519 s'oppose à toute effraction à travers l'enveloppe pour accéder au contenu du récipient comme par exemple l'introduction d'une seringue à travers le bouchon. La rondelle 519 forme en effet un bouclier d'accès au bouchon.This makes the container even more secure. In fact, the washer 519 prevents any break-in through the envelope to access the contents of the container, such as for example the introduction of a syringe through the cap. The washer 519 in fact forms an access shield to the cap.

Pour approcher le contenu du récipient, une personne devra alors manipuler l'enveloppe provoquant le déchirement de la bande de sécurité 502 comme indiqué précédemment.To approach the contents of the container, a person will then have to handle the envelope causing the security strip 502 to tear as indicated. previously.

Ceci permet en outre de sécuriser très simplement le récipient puisque la pose de la rondelle 519 se fait simultanément à celle du manchon 501.This also makes it possible to secure the container very simply since the installation of the washer 519 is done simultaneously with that of the sleeve 501.

On a montré que l'invention se prête à de nombreuses variantes. Pour définir la bande de sécurité on peut ainsi jouer sur les paramètres suivants :

  • matériau de la bande de sécurité,
  • forme et dimensions de la bande de sécurité notamment son épaisseur,
  • force de rétraction de la bande de sécurité,
  • type d'adhésion au manchon (si on utilise une colle le collage pourra par exemple être permanent, partiel ou non repositionnable),
  • la personnalisation de la bande de sécurité (par exemple ajouts d'impressions avec des encres visibles à la lumière du jour et/ou visibles dans d'autres domaines comme par exemple dans l'ultraviolet ou l'infrarouge, ajouts de métallisation, ajouts d'hologrammes ...),
  • la position relative entre la bande de sécurité et le reste des éléments (impressions, hologrammes ...) permettant de personnaliser le manchon, ceci permettra en outre de rendre plus difficile une reproduction frauduleuse de l'enveloppe de sécurité.
It has been shown that the invention lends itself to numerous variations. To define the security band, you can adjust the following parameters:
  • safety strip material,
  • shape and dimensions of the safety strip, in particular its thickness,
  • retraction force of the safety strip,
  • type of adhesion to the sleeve (if glue is used, the bonding could for example be permanent, partial or non-repositionable),
  • customization of the security band (for example additions of printing with inks visible in daylight and/or visible in other areas such as ultraviolet or infrared, additions of metallization, additions of 'holograms...),
  • the relative position between the security strip and the rest of the elements (prints, holograms, etc.) allowing the sleeve to be personalized, this will also make it more difficult to fraudulently reproduce the security envelope.

De la même façon pour définir le manchon on peut ainsi jouer sur le matériau du manchon, sur sa forme et ses dimensions (notamment son épaisseur), sa force de rétraction, son type d'adhésion au récipient, sa personnalisation et la position relative entre la bande de sécurité et le reste du manchon.In the same way to define the sleeve we can thus play on the material of the sleeve, on its shape and its dimensions (in particular its thickness), its retraction force, its type of adhesion to the container, its customization and the relative position between the safety strip and the rest of the sleeve.

L'invention n'est pas limitée à ce qui vient d'être décrit mais englobe au contraire toute variante entrant dans le cadre défini par les revendications.The invention is not limited to what has just been described but on the contrary encompasses any variant falling within the scope defined by the claims.

En particulier, bien qu'ici le manchon soit en matériau thermorétractable, le manchon pourra être dans un autre matériau et être rapporté sur le récipient par exemple par sertissage. Le manchon pourra ainsi être une capsule de surbouchage comme celle utilisée pour les bouteilles de vin. La bande de sécurité formera alors une zone de serrage du récipient une fois le manchon en place sur le récipient (par exemple par sertissage ou emboutissage).In particular, although here the sleeve is made of heat-shrinkable material, the sleeve could be made of another material and be attached to the container by for example by crimping. The sleeve could thus be an overcorking capsule like that used for wine bottles. The safety strip will then form a container clamping zone once the sleeve is in place on the container (for example by crimping or stamping).

De la même façon, la bande de sécurité pourra être en matériau thermorétractable comme en matériau non thermorétactable.In the same way, the security strip may be made of heat-shrinkable material or of non-heat-shrinkable material.

Bien qu'ici le manchon soit transparent, le manchon pourra être opaque. Le manchon pourra ainsi être opaque dans la masse ou recouvert d'une couche d'agent opaque. Le manchon pourra être transparent dans certaines zones et opaque dans d'autres.Although here the sleeve is transparent, the sleeve could be opaque. The sleeve can thus be opaque throughout or covered with a layer of opaque agent. The sleeve may be transparent in certain areas and opaque in others.

De même, la bande de sécurité pourra être opaque. La bande de sécurité pourra être opaque dans la masse ou être recouvert d'un agent opaque. La bande de sécurité pourra être transparente dans certaines zones et opaque dans d'autres.Likewise, the security strip may be opaque. The security strip may be opaque throughout or be covered with an opaque agent. The security strip may be transparent in certain areas and opaque in others.

En particulier, bien que les lignes de découpe définissent ici une portion amovible qui est séparable du reste du manchon, on pourra ne pas organiser de portion séparable. On pourra alors prévoir simplement une ou plusieurs lignes de découpe passant sur la bande de sécurité, afin de favoriser le changement d'état de la bande de sécurité en cas d'action sur le manchon. On pourra aussi ne pas prévoir de lignes de découpe sur le manchon, la simple manipulation du manchon pour tenter une ouverture du récipient étant alors suffisante pour provoquer le changement d'état de la bande de sécurité.In particular, although the cutting lines here define a removable portion which is separable from the rest of the sleeve, it is possible not to organize a separable portion. We can then simply provide one or more cutting lines passing over the safety strip, in order to promote the change of state of the safety strip in the event of action on the sleeve. It is also possible not to provide cutting lines on the sleeve, the simple manipulation of the sleeve to attempt to open the container then being sufficient to cause the change of state of the safety strip.

On pourra aussi prévoir des lignes de découpe de longueur inférieure à la circonférence complète du manchon ou à la hauteur du manchon.We can also provide cutting lines of length less than the complete circumference of the sleeve or the height of the sleeve.

Les lignes de découpe et/ou la portion de découpe pourront être agencées sur une partie du manchon de sorte à recouvrir la bande de sécurité hors d'une zone de fragilisation de ladite bande ou justement au niveau d'une zone de fragilisation de ladite bande. Par ailleurs, les lignes de découpe et/ou la portion de découpe pourront être agencées sur une partie du manchon de sorte à recouvrir la bande de sécurité au niveau d'un signe de sécurité de ladite bande. Par ailleurs, la portion de découpe pourra être agencée sur une partie du manchon de sorte à recouvrir tous les signes de sécurité de la bande de sécurité.The cutting lines and/or the cutting portion may be arranged on part of the sleeve so as to cover the safety strip outside a zone of weakening of said strip or precisely at a weakening zone of said strip. Furthermore, the cutting lines and/or the cutting portion may be arranged on a part of the sleeve so as to cover the safety strip at the level of a security sign on said strip. Furthermore, the cutting portion can be arranged on part of the sleeve so as to cover all the safety signs of the safety strip.

Les zones de fragilisation de la bande de sécurité pourront être différentes de ce qui a été décrit. Par exemple, les zones de fragilisation pourront ne pas comporter de découpe mais une composition particulière du reste de la bande de sécurité de sorte que les zones de fragilisation changent de couleur vis-à-vis du reste de la bande de sécurité en cas d'action sur le manchon.The areas of weakness of the safety band may be different from what has been described. For example, the weakened zones may not include a cutout but a particular composition of the rest of the security strip so that the weakened zones change color in relation to the rest of the security strip in the event of action on the sleeve.

En place de s'étendre sur toute la circonférence du manchon (et donc du récipient associé), la bande de sécurité pourra ne s'étendre que sur une partie seulement de la circonférence du manchon. La bande de sécurité pourra ainsi être en plusieurs parties séparées les uns des autres et réparties sur tout le pourtour de la circonférence du manchon. Typiquement la bande de sécurité pourra être en deux parties, les deux parties s'étendant symétriquement l'une par rapport à l'autre sur la circonférence du manchon.Instead of extending over the entire circumference of the sleeve (and therefore of the associated container), the safety strip may only extend over only part of the circumference of the sleeve. The safety strip can thus be in several parts separated from each other and distributed around the entire circumference of the sleeve. Typically the safety strip may be in two parts, the two parts extending symmetrically with respect to each other on the circumference of the sleeve.

L'enveloppe pourra ne pas comporter de rondelle de protection. L'enveloppe pourra comporter une goulotte même en étant de forme cylindre ou en tronc de cône ou toute autre forme.The envelope may not include a protective washer. The envelope may include a chute even if it is cylindrical or truncated cone shaped or any other shape.

Comme illustré à la figure 10, l'enveloppe pourra comporter une rondelle de protection combinée à un manchon tubulaire, la rondelle étant par exemple collée au niveau de sa périphérie à la face interne du manchon pour ne pas bouger lors de la manipulation du manchon. La rondelle s'étendra alors transversalement au manchon et à l'intérieur du manchon.As illustrated in Figure 10 , the envelope may include a protective washer combined with a tubular sleeve, the washer being for example glued at its periphery to the internal face of the sleeve so as not to move when handling the sleeve. There washer will then extend transversely to the sleeve and inside the sleeve.
