DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Selon l'invention, le moyen de fermeture inviolable d'un goulot d'un récipient, typiquement d'une bouteille, à l'aide d'une capsule comprenant une tête et une jupe fixée audit goulot durant une opération dite de capsulage, est caractérisé en ce que,

  • a) ledit goulot présente, outre une contre-bague de sertissage, au moins une gorge de profondeur H comprise entre 0,2 mm et 6 mm, et/ou de rayon de courbure R compris entre 0,2 mm et 6 mm, R ou H étant compris de préférence de 0,4 à 3 mm,
  • b) au moins une partie (50) de ladite jupe (5), celle en regard de ladite gorge lorsque ladite capsule coiffe ledit goulot, comprend, sur tout ou partie de sa surface intérieure, un adhésif (7) pour former une couche (70) apte à adhérer à tout ou partie de ladite gorge (61),
  • c) la totalité ou une fraction de ladite partie (50) de ladite jupe (5) forme un anneau rétreint (51) dans ladite gorge (61) par déformation radiale de ladite partie (50),
  • d) tout ou partie dudit anneau rétreint (51) adhère à ladite gorge (61) grâce à ladite couche (70), de manière à ce que toute tentative de séparation frauduleuse de ladite capsule se solde par la rupture dudit anneau rétreint, rendant ainsi visible ladite tentative.
    • According to the invention, the tamper-proof closure means of a neck of a container, typically a bottle, using a capsule comprising a head and a skirt attached to said neck during a so-called capping operation, is characterized in that
  • a) said neck has, in addition to a counter-crimping ring, at least one groove of depth H between 0.2 mm and 6 mm, and / or radius of curvature R between 0.2 mm and 6 mm, R or H being preferably from 0.4 to 3 mm,
  • b) at least a portion (50) of said skirt (5), the one facing said groove when said cap covers said neck, comprises, on all or part of its inner surface, an adhesive (7) to form a layer ( 70) adapted to adhere to all or part of said groove (61),
  • c) all or a fraction of said portion (50) of said skirt (5) forms a narrowed ring (51) in said groove (61) by radial deformation of said portion (50),
  • d) all or part of said shrunken ring (51) adheres to said groove (61) by said layer (70), so that any attempt to fraudulently separate said capsule results in the rupture of said shrunken ring, thereby rendering visible said attempt.

    • Cette combinaison de moyens résout l'ensemble des problèmes posés.
    En effet, d'une part, le moyen de la présente invention est non seulement totalement nouveau par rapport aux moyens anti-fraude connus, mais il est également plus efficace que les moyens connus, dans la mesure où, à ce jour, et en dépit de nombreuses tentatives, aucun enlèvement frauduleux de capsules avec un moyen de fermeture selon l'invention n'a pu être réalisé.
    Enfin, le moyen de fermeture selon l'invention est relativement peu onéreux.    This combination of means solves all the problems posed.
    Indeed, on the one hand, the means of the present invention is not only totally new compared to the known anti-fraud means, but it is also more effective than the known means, insofar as, to date, and in despite many attempts, no fraudulent removal of capsules with a closure means according to the invention could be achieved.
    Finally, the closure means according to the invention is relatively inexpensive.

    DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

    Selon l'invention, ledit anneau rétreint (51) peut présenter une déformation radiale totale correspondant sensiblement au profil de ladite gorge (61), ledit anneau rétreint étant plaqué au fond de ladite gorge (61), tout ou partie dudit anneau rétreint adhérant à ladite gorge.According to the invention, said narrowed ring (51) may present a total radial deformation corresponding substantially to the profile of said groove (61), said ring shrinks being plated at the bottom of said groove (61), all or part of said necking ring adhering to said throat.

    Comme cela a déjà été souligné, l'invention vise à obtenir, après sertissage d'une capsule sur un goulot selon l'invention, une capsule sertie sur le goulot et au moins en partie collée dans la gorge du goulot, de telle sorte que la capsule se détruise en cas de tentative frauduleuse pour enlever la capsule.
    L'invention repose sur la combinaison de deux moyens, un premier moyen de type géométrique, avec une gorge (61) non accessible sauf à détruire tout ou partie de la partie basse de la capsule, et l'autre moyen, complémentaire du précédent, visant à ce que, de préférence, l'énergie cohésive du matériau formant la capsule au niveau de ladite gorge soit, de préférence, inférieure à l'énergie adhésive entre la capsule et le goulot.
    Ces deux moyens pourraient être utilisés indépendamment l'un de l'autre selon l'invention, en particulier le second moyen pourrait être utilisé isolément. Cependant, il est préférable de les utiliser simultanément pour obtenir le meilleur résultat.
    De manière à renforcer ce second moyen, la jupe (5) de ladite capsule ou au moins ladite partie de jupe (50) peut être choisie, notamment en épaisseur, de manière à ce que ledit anneau rétreint (51) comprenne au moins une partie amincie ou fragilisée (510), de manière à renforcer le caractère inviolable dudit moyen de fermeture.     As already pointed out, the purpose of the invention is to obtain, after crimping a capsule on a neck according to the invention, a capsule crimped onto the neck and at least partly glued into the throat of the neck, so that the capsule is destroyed in case of fraudulent attempt to remove the capsule.
    The invention is based on the combination of two means, a first geometric-type means, with a groove (61) not accessible except to destroy all or part of the lower part of the capsule, and the other means, complementary to the previous one, preferably, the cohesive energy of the capsule material at said groove is preferably less than the adhesive energy between the capsule and the neck.
    These two means could be used independently of one another according to the invention, in particular the second means could be used in isolation. However, it is best to use them simultaneously to get the best result.
    In order to reinforce this second means, the skirt (5) of said capsule or at least said skirt portion (50) may be chosen, in particular in thickness, so that said necking ring (51) comprises at least a portion thinned or weakened (510), so as to reinforce the inviolability of said closure means.

    Eventuellement, la jupe (5) peut comprendre une partie amincie ou fragilisée au-dessous de l'anneau rétreint, de manière à fragiliser encore davantage la partie basse de la jupe et à rendre plus évidente toute tentative frauduleuse pour séparer la capsule de la bouteille.Optionally, the skirt (5) may comprise a thinned or weakened portion below the ring shrinks, so as to further weaken the lower part of the skirt and to make more obvious any fraudulent attempt to separate the capsule from the bottle.

    En outre, ladite déformation radiale peut être choisie, notamment en profondeur, de manière à ce que ledit anneau rétreint (51) comprenne une partie amincie ou fragilisée (510), de manière à renforcer le caractère inviolable dudit moyen de fermeture.
    Dans de nombreuses situations où des matériaux, notamment métalliques et en bande, sont déformés, il est le plus souvent recherché une déformation sans diminution locale des caractéristiques mécaniques. C'est l'inverse dans le cas de la présente invention, sans que pour autant la capsule obtenue après sertissage selon l'invention présente des défauts visibles tels que fissures.    In addition, said radial deformation may be chosen, in particular at depth, so that said necking ring (51) comprises a thinned or weakened portion (510), so as to reinforce the inviolability of said closure means.
    In many situations where materials, especially metal and strip, are deformed, it is most often sought a deformation without local decrease in mechanical characteristics. This is the opposite in the case of the present invention, without however the capsule obtained after crimping according to the invention has visible defects such as cracks.

    Selon l'invention, et comme schématisé sur la figure 2, ledit goulot (6) peut comprendre, de haut en bas, ladite contre-bague (60) et au moins un cordon annulaire (62), ladite gorge - ou lesdites gorges - (61) étant constituée par l'espace annulaire formé entre ladite contre-bague (60) et ledit cordon annulaire (62).
    Cependant, l'invention s'applique aussi lorsque le goulot (6'), comme illustré sur les figures 6a et 6b, ne comprend pas de cordon annulaire (62), ladite gorge (61) étant définie comme la partie du goulot, située au-dessous de ladite contre-bague (60) qui présente une profondeur H suffisante et/ou un rayon de courbure R suffisant.
    Dans ce cas, le rayon de courbure R' est sensiblement supérieur au rayon R de la figure 2, et la gorge (61) s'étend typiquement sur une hauteur H50 de l'ordre de 2.R'. Ce goulot (6') peut correspondre éventuellement à un goulot de fabrication standard, ce qui est avantageux sur un plan pratique.    According to the invention, and as shown diagrammatically in FIG. 2, said neck (6) may comprise, from top to bottom, said counter-ring (60) and at least one annular bead (62), said groove - or said grooves - (61) being constituted by the annular space formed between said counter-ring (60) and said annular bead (62).
    However, the invention also applies when the neck (6 '), as illustrated in Figures 6a and 6b, does not comprise an annular bead (62), said groove (61) being defined as the portion of the neck, located below said counter ring (60) which has a sufficient depth H and / or a sufficient radius of curvature R.
    In this case, the radius of curvature R 'is substantially greater than the radius R of FIG. 2, and the groove (61) typically extends over a height H 50 of the order of 2.R'. This neck (6 ') may possibly correspond to a standard manufacturing neck, which is advantageous on a practical level.

    Le moyen de fermeture selon l'invention peut s'appliquer à tout type de capsule.
    Ainsi, comme illustré sur la figure 5, ladite capsule (1) peut être une capsule de bouchage (3), comprenant typiquement un insert plastique de bouchage (30). Une telle capsule de bouchage (3) peut être une capsule en aluminium ou alliage, en étain ou alliage.     The closure means according to the invention can be applied to any type of capsule.
    Thus, as illustrated in FIG. 5, said capsule (1) may be a closure cap (3), typically comprising a plastic capping insert (30). Such a closure cap (3) may be an aluminum or alloy capsule, tin or alloy.

    De même, comme illustré sur les figures 1b, et 6b, ladite capsule (1) peut être une capsule de surbouchage (2). Cette capsule de surbouchage (2) peut être une capsule pour liquides tranquilles en aluminium ou alliages, en étain ou alliages, en matériau complexe métalloplastique, en matière plastique, capsule sertissable ou thermorétractable selon le cas.
    Enfin, comme illustré sur la figure 4, ladite capsule de surbouchage (2) peut être une coiffe (2') pour liquide effervescent sous pression, en aluminium ou alliages, en étain ou alliages, en matériau complexe métalloplastique, en matière plastique, capsule sertissable ou thermorétractable selon le cas. Sur la figure 4, on a représenté le muselet (22) qui teint le bouchon à tête (21) par un simple fil métallique.    Similarly, as illustrated in Figures 1b, and 6b, said capsule (1) may be an overcap (2). This overcap (2) can be a capsule for quiet liquids of aluminum or alloys, tin or alloys, complex metalloplastic material, plastic, crimpable capsule or heat shrinkable as appropriate.
    Finally, as illustrated in FIG. 4, said overcap (2) may be a cap (2 ') for effervescent liquid under pressure, made of aluminum or alloys, of tin or alloys, of complex metalloplastic material, of plastic material, capsule crimpable or heat shrinkable as appropriate. In Figure 4, there is shown the cap (22) which dyes the cap head (21) by a single wire.

    Ladite couche adhésive (70) peut former au moins une bande annulaire ou segmentée de largeur comprise typiquement entre 3 et 30 mm.
    Sur l'ensembles des figures, les capsules (1) selon l'invention comprennent une seule bande adhésive formant ladite couche adhésive (70), sauf sur les figures 6a et 6b où, notamment dans un souci d'économie, la capsule (2) présente deux bandes, une située au niveau de la gorge (61), et l'autre au niveau des lignes d'affaiblissement (53), de manière à réduire à néant les risques de blessure avec le bord de capsule après déchirement de la languette amovible (54).
    Lorsque la hauteur H70 de ladite couche adhésive (70) correspond à la hauteur H50 de la gorge, elle peut former une bande annulaire de largeur comprise typiquement entre 5 et 15 mm.
    Selon l'invention, il est également possible de recouvrir d'adhésif (7) la totalité de la surface intérieure de la jupe (5) de la capsule ou de capsule (1) elle-même, selon le matériau de départ servant à fabriquer ladite capsule (1) et le procédé de fabrication utilisé.    Said adhesive layer (70) may form at least one annular or segmented strip of width typically between 3 and 30 mm.
    In the set of figures, the capsules (1) according to the invention comprise a single adhesive strip forming said adhesive layer (70), except in FIGS. 6a and 6b where, for reasons of economy, the capsule (2) ) has two bands, one located at the groove (61), and the other at the weakening lines (53), so as to reduce to zero the risk of injury to the capsule edge after tearing of the removable tongue (54).
    When the height H 70 of said adhesive layer (70) corresponds to the height H 50 of the groove, it may form an annular band of width typically between 5 and 15 mm.
    According to the invention, it is also possible to cover with adhesive (7) the entire inner surface of the skirt (5) of the capsule or capsule (1) itself, depending on the starting material used to manufacture said capsule (1) and the manufacturing method used.

    Comme illustré sur les figures 3d et 6b, ladite capsule (1, 2, 2', 3) peut comprendre typiquement sur sa jupe (5) un moyen d'ouverture facile positionné au-dessus de ladite partie de jupe (50), typiquement entre ladite tête (4) et ladite partie de jupe (50), ledit moyen d'ouverture facile comprenant au moins une ligne d'affaiblissement (53). As illustrated in FIGS. 3d and 6b, said capsule (1, 2, 2 ', 3) can comprise typically on its skirt (5) an easy opening means positioned above said skirt portion (50), typically between said head (4) and said skirt portion (50), said easy opening means comprising at least one line of weakness (53).

    La jupe (5) de la capsule de la figure 3d comprend une seule ligne d'affaiblissement (53), alors que la jupe (5) de la capsule (2) de la figure 6b comprend deux lignes d'affaiblissement parallèles qui délimitent une bandelette ou languette (54) déchirable. Il est avantageux, comme illustré sur ces figures que ledit moyen d'ouverture facile soit recouvert intérieurement de ladite couche adhésive, la face intérieure correspondante de la jupe étant recouverte d'une couche adhésive (70), ce qui réduit à néant les risques de se blesser lors de l'ouverture de la bouteille.The skirt (5) of the capsule of Figure 3d comprises a single line of weakening (53), whereas the skirt (5) of the capsule (2) of FIG. 6b comprises two lines parallel weakening which delimit a strip or tongue (54) tearable. he is advantageous, as illustrated in these figures, that said easy opening means is internally coated with said adhesive layer, the corresponding inner face of the skirt being covered with an adhesive layer (70), which reduces the risks of get hurt when opening the bottle.

    Ladite couche adhésive (70) est une couche d'un vernis ou d'une matière plastique scellable à chaud sur ledit goulot (6). Typiquement, la jupe (5') de la capsule départ utilisée pour former ledit moyen de fermeture comprend, comme illustré sur la figure 1a, ladite couche adhésive (70).
    L'adhésif (7) constituant ladite couche adhésive (7) peut être un copolymère oléfinique comprenant des groupements acides, par exemple du type EAA, copolymère d'éthylène et d'acide acrylique.    Said adhesive layer (70) is a layer of a varnish or a heat sealable plastic material on said neck (6). Typically, the skirt (5 ') of the capsule used to form said closure means comprises, as illustrated in Figure 1a, said adhesive layer (70).
    The adhesive (7) constituting said adhesive layer (7) may be an olefinic copolymer comprising acid groups, for example of the EAA type, copolymer of ethylene and of acrylic acid.

    Il est avantageux que ladite partie de jupe (50) formant ledit anneau rétreint (51) soit éloignée de l'extrémité inférieure de ladite jupe (5) d'au moins 10 mm, de manière à ce que toute tentative frauduleuse pour séparer de ladite gorge ladite partie de jupe (50) formant ledit anneau rétreint (51) s'accompagne de déformations visibles et irréversibles de ladite extrémité inférieure, ce qui correspond à une hauteur de capsule sous gorge H52 d'au moins 10 mm, et de préférence d'au moins 15 mm, comme illustré sur la figure 1b.It is advantageous that said skirt portion (50) forming said necking ring (51) is spaced from the lower end of said skirt (5) by at least 10 mm, so that any fraudulent attempt to separate from said groove said skirt portion (50) forming said narrowed ring (51) is accompanied by visible and irreversible deformations of said lower end, which corresponds to a height of under-groove capsule H 52 of at least 10 mm, and preferably at least 15 mm, as illustrated in Figure 1b.

    Un autre objet de l'invention est constitué par un procédé de fabrication dudit moyen de fermeture selon l'invention, dans lequel :

  • a) on approvisionne ledit récipient doté dudit goulot (6), et ladite capsule (1, 2, 2', 3), et on fixe ladite capsule sur ledit goulot, par sertissage et/ou thermorétractation selon la nature de ladite capsule,
  • b) on déforme ladite partie de jupe (50) de manière à plaquer ladite partie contre ladite gorge et ainsi à former ledit anneau rétreint (51), et à le faire adhérer à ladite gorge par thermoscellage, typiquement à l'aide d'une molette tournante portée à une température suffisante pour assurer le scellage de ladite partie sur ledit goulot, ladite molette présentant un bord actif à rayon de courbure inférieur ou égal à R.
    • Another object of the invention is constituted by a method of manufacturing said closure means according to the invention, in which:
  • a) supplying said container provided with said neck (6), and said capsule (1, 2, 2 ', 3), and fixing said capsule on said neck, by crimping and / or heat shrinking according to the nature of said capsule,
  • b) deforming said skirt portion (50) so as to press said portion against said groove and thereby forming said necking ring (51), and adhering it to said groove by heat sealing, typically using a rotating wheel raised to a temperature sufficient to seal said portion on said neck, said wheel having an active edge radius of curvature less than or equal to R.

    • On peut aussi, utiliser, à la place de ladite molette tournante, un outil de thermoscellage de forme qui est appliqué contre ledit goulot (6) en rotation.
    On peut utiliser en outre tout moyen de chauffage permettant d'obtenir une vitesse de thermoscellage élevée compatible avec les cadences de capsulage. Ainsi, il possible d'utiliser en outre seuls ou en combinaison les moyens suivants : soufflage d'air chaud, chauffage par induction et par courants HF (hautes fréquences).
    De même, la formation dudit anneau rétreint (51) peut être effectué simultanément au sertissage de ladite capsule, ou éventuellement antérieurement au sertissage de ladite capsule.
    Il est ainsi possible de sertir ladite capsule de manière standard, puis d'appliquer localement sur la partie (50) de la jupe une molette ou un outil de manière à déformer localement ladite jupe et ainsi former ledit anneau rétreint (51) localement d'épaisseur réduite, en le faisant adhérer à ladite gorge par pression et chauffage localisés, la partie restante de la jupe, notamment la partie inférieure (52) étant typiquement immobilisée.    It is also possible to use, in place of said rotating wheel, a form heat sealing tool which is applied against said neck (6) in rotation.
    Any heating means can also be used to obtain a high heat sealing speed compatible with the capping rates. Thus, it is possible to further use alone or in combination the following means: hot air blowing, induction heating and HF (high frequency) currents.
    Similarly, the formation of said narrowed ring (51) can be performed simultaneously with the crimping of said capsule, or possibly prior to the crimping of said capsule.
    It is thus possible to crimp said capsule in a standard manner, then to locally apply on the portion (50) of the skirt a wheel or a tool so as to locally deform said skirt and thus form said ring shrunk (51) locally of reduced thickness, by making it adhere to said groove by localized pressure and heating, the remaining portion of the skirt, in particular the lower portion (52) being typically immobilized.

    EXEMPLES DE REALISATIONEXAMPLES OF REALIZATION

    Les moyens de fermeture, tels qu'illustrés sur les figures 1a à 6a constituent des exemples de réalisation.

    • and neck "B" according to Figure 6a, with R = 0.8 mm, H = 1.5 mm and H 50 = 7 mm

    On a utilisé comme adhésif (7) un copolymère du commerce à base d'éthylène et d'acide acrylique applicable par enduction ou pulvérisation. As adhesive (7), a commercial copolymer based on ethylene and acid was used Applicable acrylic by coating or spraying.

    On a fabriqué des capsules de surbouchage (2) correspondant aux moyens de fermeture selon les figures 1a, 1b, 6b, et adaptées aux deux types de goulots A et B.
    Ces capsules (2) sont en aluminium, avec une épaisseur de jupe comprise entre 50 et 90 µm dans la partie (50) en regard de la gorge (61).
    Les modalités de capsules correspondant aux figures 3a à 3d, et 6b ont été réalisées :

    • pour la modalité de la figure 3a, on a pris :
      H70 = H71 = 8 mm pour le goulot A où H50 = 5 mm, - H70 = H71 = 10 mm pour le goulot B où H50 = 8 mm.
    • pour la modalité de la figure 3b, on a pris H70 = H71 = H50.
    • pour la modalité de la figure 3c, on a pris :
      H70 = 20 mm
      H71 = 2 x 4 mm pour le goulot A et 2 x 5 mm pour le goulot B
    • pour la modalité de la figure 3d, on a pris :
      H70 = 30 mm, de manière à ce qu'il y ait de l'adhésif au niveau de la ligne d'affaiblissement (53),

    • pour la modalité de la figure 6b, on a pris :
      H70 = H71 = H50 pour la partie adhésive correspondant à la gorge (61
      H'70 = 12 mm pour la partie de la jupe comprenant une couche adhésive - mais non adhérente au goulot - au niveau de la languette d'ouverture (54).
      Toutes ces modalités ont été réalisées en pulvérisant localement ledit adhésif (7) sur l'intérieur de la jupe (5) pour former ladite couche d'adhésif (70).
      Par ailleurs, on a réalisé également des capsules à partir de bande d'aluminium recouverte d'adhésif.
    Overcap caps (2) corresponding to the closing means according to FIGS. 1a, 1b and 6b have been manufactured and adapted to both types of necks A and B.
    These capsules (2) are made of aluminum, with a skirt thickness of between 50 and 90 μm in the portion (50) facing the groove (61).
    The capsules modalities corresponding to FIGS. 3a to 3d, and 6b have been carried out:
    • for the modality of Figure 3a, we took:
      H 70 = H 71 = 8 mm for the neck A where H 50 = 5 mm, - H 70 = H 71 = 10 mm for the neck B where H 50 = 8 mm.
    • for the modality of FIG. 3b, H 70 = H 71 = H 50 was taken .
    • for the modality of Figure 3c, we took:
      H 70 = 20 mm
      H 71 = 2 x 4 mm for the neck A and 2 x 5 mm for the neck B
    • for the modality of figure 3d, we took:
      H 70 = 30 mm, so that there is adhesive at the line of weakness (53),
      H 71 = H 50
    • for the modality of Figure 6b, we have taken:
      H 70 = H 71 = H 50 for the adhesive part corresponding to the groove (61
      H '70 = 12 mm for the portion of the skirt comprising an adhesive layer - but not adherent to the neck - at the opening tab (54).
      All of these have been accomplished by locally spraying said adhesive (7) on the inside of the skirt (5) to form said adhesive layer (70).
      In addition, capsules were also made from aluminum tape coated with adhesive.

    On a fabriqué des capsules de bouchage (3) correspondant aux moyens de fermeture selon la figure 5, et adaptées aux deux types de goulots A et B, en aluminium avec une épaisseur de jupe comprise entre 65 et 250 µm.
    Les même modalités de capsules que celles indiquées précédemment ont été réalisées.     Capsules (3) corresponding to the closure means according to FIG. 5, and adapted to the two types of necks A and B, made of aluminum with a skirt thickness of between 65 and 250 μm, were manufactured.
    The same capsule modalities as those indicated above were carried out.

    On a fabriqué des coiffes (2') correspondant aux moyens de fermeture selon la figure 4, et adaptées aux deux types de goulots A et B, en complexe métalloplastique Al/PE/Al où Al désigne une feuille d'aluminium de 20 µm d'épaisseur, et PE une couche intérieure de PE de 20 µm d'épaisseur.
    Les même modalités de capsules que celles indiquées précédemment ont été réalisées.    Covers (2 ') corresponding to the closing means according to FIG. 4, and adapted to the two types of necks A and B, were manufactured from Al / PE / Al metal complex where Al denotes a 20 μm aluminum foil. thickness, and PE an inner layer of PE 20 μm thick.
    The same capsule modalities as those indicated above were carried out.

    Les capsules (1, 2, 2', 3) ont été appliquées ou serties normalement sur les goulots A et B.
    On a ensuite utilisé le dispositif (8) de la figure 7 pour former ledit moyen de fermeture inviolable.
    Ce dispositif (8) comprend :

    • un système d'entraínement du goulot (80) et un guide supérieur du goulot (81), pour positionner le goulot et le mettre en rotation,
    • un outil de thermoscellage de forme (82) avec un guide latéral formant une butée radiale (83) porté par un positionneur axial et radial (84), l'outil (82) comprenant une résistance électrique (85).
      On a utilisé un outil (82) ayant un rayon de courbure égal à R.
      Dans le cas de la figure 3c, on a obtenu un amincissement significatif de la jupe notamment en empêchant que la partie basse (52) de la jupe suive l'écoulement du métal durant la formation dudit cordon annulaire (62).
      Dans certains essais, on a également utilisé du chauffage par induction pour augmenter la cadence de thermoscellage.
      Dans d'autre essais, on a également préchauffé les bagues avant thermoscellage.
    The capsules (1, 2, 2 ', 3) were applied or crimped normally on the necks A and B.
    The device (8) of FIG. 7 was then used to form said tamper-proof closure means.
    This device (8) comprises:
    • a neck drive system (80) and an upper neck guide (81) for positioning the neck and rotating it,
    • a shape heat sealing tool (82) with a lateral guide forming a radial abutment (83) carried by an axial and radial positioner (84), the tool (82) comprising an electrical resistor (85).
      A tool (82) having a radius of curvature equal to R.
      In the case of Figure 3c, there has been a significant thinning of the skirt including preventing the lower part (52) of the skirt follows the flow of the metal during the formation of said annular cord (62).
      In some tests, induction heating has also been used to increase the rate of heat sealing.
      In other tests, the rings were also preheated before heat sealing.

    Résultats obtenus :Results obtained:

    On essayé par tout moyen, notamment à l'aide de lames très fines, de séparer la capsule (1) du goulot (6).
    Dans tous les cas, il a été impossible de séparer une capsule intacte susceptible d'être réutilisée frauduleusement sans que cela se voit ou puisse être vu par un consommateur d'attention moyenne.
    Le moyen de fermeture selon l'invention permet donc de résoudre les problèmes posés.     We tried by any means, including using very thin blades, to separate the capsule (1) of the neck (6).
    In any case, it was impossible to separate an intact capsule that could be reused fraudulently without it being visible or seen by a consumer of average attention.
    The closure means according to the invention thus makes it possible to solve the problems posed.
