Description

La présente invention concerne le domaine de l'emballage.The present invention relates to the field of packaging.

Elle concerne plus particulièrement un bouchon en plastique destiné à équiper un col de récipient. Le bouchon comprend un corps cylindrique supportant un élément de fermeture intégré qui peut être ouvert ou fermé de manière indépendante de la position du corps du bouchon sur le col de la bouteille.It relates more particularly to a plastic cap intended to equip a container neck. The cap comprises a cylindrical body supporting an integrated closure element which can be opened or closed independently of the position of the body of the cap on the neck of the bottle.

Le corps du bouchon est fixé par encliquetage sur un col de récipient tel que par exemple une bouteille en plastique. A cet effet, une saillie annulaire de retenue s'étendant radialement depuis la paroi intérieure du corps du bouchon est prévue pour venir s'encliqueter sur le col du récipient.The body of the cap is fixed by snapping on a container neck such as for example a plastic bottle. For this purpose, an annular retaining projection extending radially from the inner wall of the plug body is provided to snap onto the neck of the container.

Ce mode de fixation permet d'interdire la désolidarisation du bouchon et du col du récipient après que ce dernier a été rempli d'une boisson alimentaire, dans le but de limiter sa réutilisation, et d'éviter le développement de germes dans les parties du bouchon difficilement nettoyables.This method of attachment makes it possible to prohibit the separation of the stopper and the neck of the container after the latter has been filled with a food drink, in order to limit its reuse, and to prevent the development of germs in the parts of the container. plug difficult to clean.

L'élément de fermeture est adapté à l'usage prévu du récipient, et peut être formé, à titre d'exemple, par un obturateur de type push/pull circulant selon un axe donné, ou par un couvercle rabattable pivotant autour d'un axe. Dans ce dernier cas, le fond du bouchon peut comprendre un voile déchirable permettant d'isoler le contenu du récipient jusqu'à son utilisation finale.The closure element is adapted to the intended use of the container, and may be formed, for example, by a push / pull type shutter circulating along a given axis, or by a folding lid pivoting about a axis. In the latter case, the bottom of the cap may comprise a tearable veil for isolating the contents of the container to its final use.

Un bouchon comprenant ces caractéristiques est décrit à titre d'exemple dans la publication US 5 680 965 . Toutefois l'usage de ce type de bouchon est limité à des cols de récipient ne comportant pas de filets mâles.A plug including these features is described by way of example in the publication US 5,680,965 . However, the use of this type of cap is limited to container necks not having male threads.

La production en grandes séries des bouteilles en polytéréphtalate d'éthylène (PET) destinées à l'industrie alimentaire a conduit à la standardisation de la forme des cols. Ces cols de bouchon comportent un filetage mâle comprenant un ou plusieurs filets ainsi qu'une collerette annulaire d'inviolabilité située axialement en dessous des filets.The large-scale production of polyethylene terephthalate (PET) bottles for the food industry has led to the standardization of neck shapes. These plug necks comprise a male thread comprising one or more threads and an annular tamper-proof collar located axially below the threads.

La publication EP 1 077 883 , qui divulgue les caractéristiques du préambule de la revendication 1 annexée, propose un perfectionnement du bouchon décrit dans la publication US 5 680 965 , et permettant la fixation dudit bouchon sur un col de bouteille de type standard comportant des filetages mâles.The publication EP 1 077 883 , which discloses the features of the preamble of appended claim 1, proposes an improvement of the plug described in the publication US 5,680,965 , and allowing the fixing of said cap on a standard type bottle neck having male threads.

La paroi intérieure du corps du bouchon ne présente pas de filetage femelle. La position de la saillie de retenue est ajustée pour permettre la mise en prise de ladite saillie de retenue avec la face de retenue inférieure de la collerette d'inviolabilité. Il est prévu dans ladite publication que, dans cette position, le bord supérieur du col du récipient vienne en contact avec la paroi intérieure du fond du bouchon afin d'éviter tout mouvement axial de ce dernier. La fixation du bouchon sur le col du récipient s'effectue en introduisant en force le bouchon sur le col selon une direction axiale jusqu'à l'encliquetage de la saillie de retenue sous la collerette d'inviolabilité.The inner wall of the plug body does not have a female thread. The position of the retaining projection is adjusted to allow engagement of said retaining protrusion with the lower retaining face of the tamper-evident flange. It is provided in said publication that, in this position, the upper edge of the neck of the container comes into contact with the inner wall of the bottom of the cap to prevent axial movement of the latter. Fixing the cap on the neck of the container is effected by introducing the plug force on the neck in an axial direction until the snap of the retaining projection under the tamperproof collar.

Toutefois, ce mode de fixation peut présenter certains inconvénients. En effet, en raison de la pression exercée par le bord supérieur du col du récipient sur la paroi du fond du bouchon, on observe une déformation plus ou moins permanente de la paroi du fond laquelle, au-delà des effets esthétiques non désirables, est susceptible de dégrader le voile déchirable et, en modifiant la position de la jupe intérieure d'étanchéité, d'altérer la liaison étanche entre la jupe et la paroi interne de l'embouchure.However, this method of attachment may have certain disadvantages. Indeed, due to the pressure exerted by the upper edge of the neck of the container on the bottom wall of the plug, there is a more or less permanent deformation of the bottom wall which, beyond the undesirable aesthetic effects, is which can degrade the tear-off film and, by modifying the position of the inner sealing skirt, alter the sealing connection between the skirt and the inner wall of the mouthpiece.

L'invention a pour objet d'apporter une solution originale au problème posé ci-dessus.The object of the invention is to provide an original solution to the problem posed above.

Le bouchon selon l'invention est du type à fixer par encliquetage sur un col de récipient comportant un ou plusieurs filets mâles.The plug according to the invention is of the type to be fixed by snapping on a container neck comprising one or more male threads.

L'invention est constituée de l'ensemble formé de la combinaison :

  • d'un bouchon comprenant
    • ∘ un corps cylindrique d'axe donné, comportant une paroi intérieure, et supportant des moyens d'encliquetage constitués par une saillie de retenue,
    • ∘ un fond disposé sur un côté axialement supérieur du corps cylindrique selon l'une quelconque des revendications précédentes, et dans lequel les moyens d'encliquetage sont constitués par une saillie de retenue, et supportant des éléments de fermeture intégrés pouvant être ouverts ou fermés de manière indépendante,
  • et d'un récipient muni d'un col surmonté d'une embouchure comprenant des filets mâles ayant une surface d'appui supérieure et une collerette d'inviolabilité comportant une face de retenue inférieure apte à retenir la saillie de retenue après encliquetage de ladite saillie de retenue sur ladite collerette d'inviolabilité,
The invention consists of the combination of:
  • a cap including
    • A cylindrical body of given axis, comprising an inner wall, and supporting latching means constituted by a retaining projection,
    • ∘ a bottom disposed on an axially upper side of the cylindrical body according to any one of the preceding claims, and wherein the latching means are constituted by a retaining projection, and supporting integrated closure elements that can be opened or closed by independently,
  • and a container having a neck surmounted by a mouthpiece comprising male threads having an upper bearing surface and a tamper-evident flange having a lower retaining face adapted to retain the retaining projection after snapping of said protrusion retaining on said tamper collar,

L'invention se caractérise en ce que la paroi intérieure du corps cylindrique comprend un épaulement annulaire distinct de la saillie de retenue s'étendant radialement vers l'intérieur du corps cylindrique, et situé à une distance de la paroi intérieure du fond du bouchon qui est strictement supérieure à une distance entre la surface d'appui supérieure des filets et un bord supérieur de l'embouchure du col, de sorte que l'épaulement annulaire vient buter sur la surface d'appui supérieure des filets mâles lorsque le bouchon est fixé par encliquetage sur le col du récipient, en faisant obstacle à l'enfoncement du bouchon sur le col, et que le bord supérieur de l'embouchure du col du récipient n'est pas en contact avec la paroi intérieure du fond du bouchon.The invention is characterized in that the inner wall of the cylindrical body comprises an annular shoulder distinct from the retaining projection extending radially inwardly of the cylindrical body, and located at a distance from the inner wall of the bottom of the plug which is strictly greater than a distance between the upper bearing surface of the threads and an upper edge of the mouth of the neck, so that the annular shoulder abuts on the upper bearing surface of the male threads when the cap is fixed snap on the neck of the container, preventing the insertion of the cap on the neck, and that the upper edge of the mouth of the neck of the container is not in contact with the inner wall of the bottom of the cap.

Le corps cylindrique est dimensionné en fonction du col du récipient, de manière à s'enfoncer au-dessus du col en coiffant ses filets mâles. Il résulte de cet agencement que les efforts exercés dans la direction axiale sur le bouchon lors de l'opération d'encliquetage s'exercent exclusivement sur la paroi du corps du bouchon, et laissent ledit fond libre de toute contrainte.The cylindrical body is sized according to the neck of the container, so as to sink above the neck capping its male threads. It follows from this arrangement that the forces exerted in the axial direction on the plug during the latching operation are exerted exclusively on the wall of the plug body, and leave said bottom free of any stress.

L'invention comprend également les caractéristiques suivantes considérées isolément ou en combinaison les unes avec les autres,

  • L'épaulement annulaire circule de manière continue sur toute la circonférence du corps cylindrique.
  • La paroi intérieure du corps cylindrique ne comporte pas de filets femelles.

Le fond supporte des éléments de fermeture 12, formés dans le cas d'espèce, par un couvercle articulé autour d'un axe 120. De manière à préserver l'intégrité du contenu du récipient jusqu'à son utilisation finale, un voile déchirable 14 s'étend sur la partie centrale du fond 11. Un anneau 140 permet d'extraire le voile déchirable 14 et de libérer un passage pour l'écoulement du liquide contenu dans le récipient. Le fond 11 supporte également une jupe intérieure 13 de forme cylindrique permettant d'assurer une bonne étanchéité entre le bouchon et le col du récipient.On the upper axial end of the cylindrical body 10 is disposed the bottom 11 of the plug. The bottom supports closure elements 12, formed in the case in point, by a cover hinged about an axis 120. In order to preserve the integrity of the contents of the container until its final use, a tear-off veil 14 extends over the central part of the bottom 11. A ring 140 makes it possible to extract the tear-off film 14 and to release a passage for the flow of the liquid contained in the container. The bottom 11 also supports an inner skirt 13 of cylindrical shape to ensure a good seal between the cap and the neck of the container.

La paroi intérieure 100 du corps cylindrique 10 est dépourvue de filetage femelle et présente une surface sensiblement lisse. A proximité du bord inférieur 108 du corps cylindrique 10, est disposée une saillie de retenue 101 s'étendant radialement depuis la paroi intérieure 100 vers la partie centrale du corps cylindrique 10 du bouchon. Cette saillie de retenue 101 comprend une face d'appui supérieure 102. La saillie de retenue 101 forme les moyens d'encliquetage destinés à maintenir le bouchon fixé sur le col du récipient.The inner wall 100 of the cylindrical body 10 is devoid of female thread and has a substantially smooth surface. Near the lower edge 108 of the cylindrical body 10 is disposed a retaining projection 101 extending radially from the inner wall 100 to the central portion of the cylindrical body 10 of the plug. This retaining projection 101 includes an upper bearing face 102. The retaining projection 101 forms the detent means for holding the cap attached to the neck of the container.

Dans un mode de réalisation préféré de l'invention, la paroi intérieure du corps cylindrique ne présente pas de filetage femelle. Le vissage du bouchon sur le col est alors inutile, dès lors que le bouchon peut s'encliqueter sur le col.In a preferred embodiment of the invention, the inner wall of the cylindrical body does not have a female thread. Screwing the cap on the neck is then useless, since the cap can snap on the neck.

Tout en restant dans le cadre de l'invention, la paroi intérieure du corps cylindrique pourrait toutefois comporter des filetages femelles (non illustré) aptes à engrener les filetages mâles du col. Dans cette configuration, le bouchon se visse sur le col avant de s'y encliqueter.While remaining within the scope of the invention, the inner wall of the cylindrical body could, however, include female threads (not shown) capable of meshing the male threads of the neck. In this configuration, the cap is screwed onto the neck before snapping into it.

Dans une variante de ce mode de réalisation, les filetages femelles ont un profil en section axiale en forme de rampe pour permettre, par déformation élastique du bouchon ou au moins des filetages femelles, l'enfoncement du bouchon sans rotation sur le col.In an alternative embodiment of this embodiment, the female threads have an axial section profile in the form of a ramp to allow, by elastic deformation of the plug or at least female threads, the depression of the plug without rotation on the neck.

Dans la partie supérieure de la paroi 100 du corps cylindrique, ladite paroi 100 présente une partie supérieure 103 formant un décrochement par rapport à la partie inférieure de la paroi. Au niveau de ce décrochement la paroi a une épaisseur e1 supérieure à l'épaisseur e2 de la partie inférieure de la paroi du corps cylindrique. Le décrochement forme un épaulement annulaire 104, de diamètre intérieur Φ1, s'étendant radialement depuis la paroi 100 vers l'intérieur du corps cylindrique 10 du bouchon. Cet épaulement annulaire 104 circule de manière continue sur toute la circonférence de la paroi 100. L'épaulement annulaire 104 s'étend dans un plan sensiblement perpendiculaire à l'axe XX'.In the upper part of the wall 100 of the cylindrical body, said wall 100 has an upper portion 103 forming a recess relative to the lower part of the wall. At this recess the wall has a thickness e 1 greater than the thickness e 2 of the lower part of the wall of the cylindrical body. The recess forms an annular shoulder 104, of internal diameter Φ 1 , extending radially from the wall 100 towards the inside of the cylindrical body 10 of the plug. This annular shoulder 104 circulates continuously over the entire circumference of the wall 100. The annular shoulder 104 extends in a plane substantially perpendicular to the axis XX '.

Dans l'exemple illustré à la figure 1, la partie supérieure 103 d'épaisseur e1 se prolonge axialement jusqu'à la paroi 110 du fond 11 du bouchon. Cet arrangement permet de simplifier les opérations de fabrication en supprimant toutes les zones en contredépouille.In the example shown in figure 1 , the upper part 103 of thickness e 1 is extended axially to the wall 110 of the bottom 11 of the plug. This arrangement simplifies manufacturing operations by removing all areas underdepoise.

La figure 2 illustre un col de récipient 2 de type standard d'axe XX'. Ce col de récipient comprend au moins un filet mâle 22. Le nombre de filets représentés dans l'exemple servant de support à la présente description est égal à trois, ce qui constitue un mode de réalisation très couramment répandu. Toutefois, ce nombre n'est pas limitatif. Chaque filet comporte sur sa partie axialement supérieure une surface d'appui 220. L'embouchure 23 du col est délimitée par un bord supérieur 230.The figure 2 illustrates a container neck 2 of the standard type of axis XX '. This container neck comprises at least one male thread 22. The number of threads represented in the example used as a support for the present description is equal to three, which is a very widely used embodiment. However, this number is not limiting. Each thread has on its axially upper portion a bearing surface 220. The mouth 23 of the neck is delimited by an upper edge 230.

Le col de type standard tel que représenté à la figure 2, comporte également une collerette d'inviolabilité 21, s'étendant radialement vers l'extérieur du col, et originellement prévue pour coopérer avec une bague d'inviolabilité détachable située sur un bouchon vissé (non représenté) et comportant de ce fait des filets femelles. La collerette d'inviolabilité supporte une face de retenue inférieure 210.The standard type collar as shown in FIG. figure 2 , also comprises a tamper-evident flange 21, extending radially outwardly of the neck, and originally intended to cooperate with a detachable tamper-evident ring located on a screw cap (not shown) and thereby having female threads. . The tamper-evident flange supports a lower retaining face 210.

Le col 2 comporte enfin, dans sa partie basse, un collet d'appui 24, présentant une face d'appui supérieure 240.The neck 2 finally has, in its lower part, a support collar 24, having an upper bearing surface 240.

La figure 3 illustre le cas dans lequel le bouchon 1 est fixé par encliquetage sur le col 2 du récipient. L'élément de fermeture 12 est représenté en position ouverte.The figure 3 illustrates the case in which the cap 1 is fixed by snapping on the neck 2 of the container. The closure member 12 is shown in the open position.

Le bouchon 2 est introduit sur le col selon la direction axiale XX' jusqu'à ce que la saillie de retenue 101 vienne en prise avec la collerette d'inviolabilité 21. Dans cette position, la face d'appui supérieure 102 de la saillie de retenue 101 est en contact avec la face de retenue inférieure 210 de la collerette d'inviolabilité 21, et la position axiale de l'épaulement annulaire 104 est ajustée pour venir également en contact avec la surface d'appui supérieure 220 des filets 22. Le bouchon 1, qui est alors fixé par encliquetage sur le col 2, est privé de mouvement selon les deux directions de l'axe XX'.The plug 2 is introduced on the neck in the axial direction XX 'until the retaining projection 101 engages with the tamper-evident collar 21. In this position, the upper bearing surface 102 of the projection of retainer 101 is in contact with the lower retaining face 210 of the tamper-evident flange 21, and the axial position of the annular shoulder 104 is adjusted to also come into contact with the upper bearing surface 220 of the threads 22. plug 1, which is then fixed by snapping on the neck 2, is deprived of movement in both directions of the XX 'axis.

Lorsque le col comprend trois filets, ce qui est le cas le plus répandu, l'épaulement annulaire 104 repose sur les surfaces d'appuis supérieures 220 de chacun des filets 22 en trois points équirépartis angulairement sur la périphérie du col 2 du récipient.When the neck comprises three threads, which is the most common case, the annular shoulder 104 rests on the upper bearing surfaces 220 of each of the threads 22 at three points equidistantly angularly on the periphery of the neck 2 of the container.

La jupe intérieure d'étanchéité 12, dont le diamètre extérieur correspond sensiblement au diamètre intérieur du col du récipient, pénètre en force à l'intérieur de l'embouchure 23 et assure un contact étanche avec la surface intérieure de ladite embouchure 23.The inner sealing skirt 12, whose outer diameter substantially corresponds to the inside diameter of the neck of the container, penetrates forcibly inside the mouth 23 and provides a sealing contact with the inner surface of said mouth 23.

On observe que le bord supérieur 230 de l'embouchure 23 n'est pas en contact avec la paroi intérieure 110 du fond 11 du bouchon 1.It is observed that the upper edge 230 of the mouth 23 is not in contact with the inner wall 110 of the bottom 11 of the plug 1.

Ainsi, l'ensemble des contraintes axiales engendrées par les forces de retenues du bouchon sur le col est supportée par le corps 10. Et le fond du bouchon 11, ne subit aucune déformation non désirée susceptible de modifier la position de la jupe intérieure d'étanchéité 13, ou d'altérer le voile déchirable 14.Thus, all the axial stresses generated by the retaining forces of the plug on the neck is supported by the body 10. And the bottom of the plug 11, undergoes no unwanted deformation may change the position of the inner skirt of sealing 13, or to alter the tearable veil 14.

Il résulte des dispositions précédentes que la distance a (voir figure 1) entre l'épaulement annulaire 104 et la face d'appui supérieure 102 de la saillie de retenue 101 est sensiblement égale à la distance a' entre la surface d'appui supérieure 220 des filets 22 et la face de retenue inférieure 210 de la collerette d'inviolabilité 21. Un ajustement de ces cotes peut s'avérer toutefois nécessaire pour tenir compte de l'aspect conique de la forme des filets 22 sur lesquels repose l'épaulement annulaire 104.It follows from the preceding provisions that the distance has (see figure 1 ) between the annular shoulder 104 and the upper bearing face 102 of the retaining projection 101 is substantially equal to the distance a 'between the upper bearing surface 220 of the threads 22 and the lower retaining face 210 of the collar However, an adjustment of these dimensions may be necessary to take account of the conical appearance of the shape of the threads 22 on which the annular shoulder 104 rests.

De même, la distance b' mesurée entre la surface d'appui supérieure 220 des filets 22 et le bord supérieur 230 de l'embouchure 23 du col du récipient est strictement inférieure à la distance b mesurée entre l'épaulement annulaire 104 et la paroi intérieure 110 du fond 11 du bouchon.Similarly, the distance b 'measured between the upper bearing surface 220 of the threads 22 and the upper edge 230 of the mouth 23 of the container neck is strictly less than the distance b measured between the annular shoulder 104 and the wall 110 inside the bottom 11 of the cap.

Enfin, la valeur du diamètre intérieur de la collerette annulaire Φ1 doit être comprise entre le diamètre extérieur Φ2 des filets 22 et le diamètre extérieur Φ3 de l'embouchure du col du récipient.Finally, the value of the inside diameter of the annular flange Φ 1 must be between the outside diameter Φ 2 of the threads 22 and the outside diameter Φ 3 of the mouth of the neck of the container.

Les valeurs des cotes a' et b' sont définies par les standards en usage dans la profession. Ainsi, pour un produit de consommation courante tel qu'un col de bouteille PET 3 filets, de diamètre 38 mm, la valeur de la cote a', sensiblement égale à la valeur de la cote a, est de 8,9 mm, et la valeur de la cote b', strictement inférieure à la valeur de la cote b, est de 1,9 mm. La valeur du diamètre Φ1 est comprise entre 36 mm +/- 0,15 mm et 38 mm +/-0,15mm.The values of the ratings a 'and b' are defined by the standards used in the profession. Thus, for a consumer product such as a 3-thread PET bottle neck, with a diameter of 38 mm, the value of the dimension a ', substantially equal to the value of the dimension a, is 8.9 mm, and the value of the dimension b ', strictly less than the value of the dimension b, is 1.9 mm. The diameter value Φ 1 is between 36 mm +/- 0.15 mm and 38 mm +/- 0.15 mm.

La figure 4 illustre une première variante de réalisation de l'invention, dans laquelle le bouchon diffère du bouchon illustré à la figure 1 en ce que l'épaulement annulaire est formé par la face inférieure 107 d'une collerette intérieure 105. Cette collerette intérieure comporte une paroi supérieure 106 distincte de la paroi intérieure 110 du fond 11 du bouchon. Cette forme de réalisation peut s'avérer intéressante lorsque, en jouant sur l'épaisseur axiale de la collerette intérieure 105, on ajuste l'élasticité axiale de ladite collerette intérieure 105 dans le but de conférer une certaine souplesse à la fixation du bouchon sur le col par encliquetage, et de rendre l'encliquetage moins sensible aux écarts de tolérance.The figure 4 illustrates a first embodiment of the invention, in which the plug differs from the plug shown in FIG. figure 1 in that the annular shoulder is formed by the lower face 107 of an inner flange 105. This inner flange comprises an upper wall 106 separate from the inner wall 110 of the bottom 11 of the cap. This embodiment can be of interest when, by acting on the axial thickness of the inner flange 105, the axial elasticity of said inner flange 105 is adjusted in order to give some flexibility to the fastening of the cap on the inner flange 105. snap-on collar, and make snapping less sensitive to tolerance deviations.

La figure 5 illustre une seconde variante de réalisation de l'invention dans laquelle, pour améliorer l'étanchéité globale du bouchon, le bord inférieur 108 du corps 10 du bouchon vient en contact avec la face d'appui supérieure 240 du collet d'appui 24. A cet effet, la distance c qui sépare la face d'appui supérieure 102 de la saillie de retenue 101 et le bord inférieur 108 du corps cylindrique 10 du bouchon est sensiblement égale à la valeur c' de la distance entre la face de retenue inférieure 210 de la collerette d'inviolabilité 21 et la face d'appui supérieure 240 du collet d'appui 24.The figure 5 illustrates a second embodiment of the invention wherein, to improve the overall sealing of the plug, the lower edge 108 of the body 10 of the cap comes into contact with the upper bearing surface 240 of the support collar 24. A this effect, the distance c between the upper bearing face 102 of the retaining projection 101 and the lower edge 108 of the cylindrical body 10 of the plug is substantially equal to the value c 'of the distance between the lower retaining face 210 the tamper-evident collar 21 and the upper bearing face 240 of the support collar 24.

Dans le cas du col de la bouteille PET 3 filets citée ci-dessus, cette distance est sensiblement égale à 4,5 mm.In the case of the neck of the PET 3-threaded bottle mentioned above, this distance is substantially equal to 4.5 mm.

La réalisation d'un bouchon tel que décrit ci-dessus se fait par moulage par injection d'un matériau thermoplastique tel que, à titre d'exemple non limitatif, du Polyéthylène (PE), du Polyéthylène haute densité (PEhd), du Polypropylène (PP), du Polychlorure de vinyle (PVC), du Polytéréphtalate d'éthylène (PET), du Polyvinyldiène chloride (PVDC), ou un mélange de ces composants.The production of a plug as described above is by injection molding of a thermoplastic material such as, by way of non-limiting example, polyethylene (PE), high density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyvinyl diene chloride (PVDC), or a mixture of these components.
