Description

La présente invention a pour objet un bouchon destiné à obturer une bouteille ou flacon en matière plastique ou en verre qui comporte un col présentant un filetage extérieur.The subject of the present invention is a stopper intended to close a plastic or glass bottle or flask which comprises a neck having an external thread.

Actuellement, pour obturer une bouteille, on utilise soit des bouchons métalliques, soit des bouchons en matière plastique. Toutefois, quel que soit le matériau dans lequel sont réalisés ces bouchons, ils doivent présenter une structure qui offre des propriétés suffisantes d'étanchéité tout en les préservant d'une ouverture non désirée.Currently, to seal a bottle, either metal caps or plastic caps are used. However, whatever the material from which these plugs are made, they must have a structure which offers sufficient sealing properties while preserving them from an unwanted opening.

En ce qui concerne l'étanchéité, dans le cas de bouchons en matière plastique, on connait par exemple un bouchon qui comporte un corps présentant un plateau qui comporte une lèvre apte à venir s'emboîter à l'intérieur du goulot de la bouteille.As regards sealing, in the case of plastic caps, there is known for example a cap which comprises a body having a plate which comprises a lip capable of coming to fit inside the neck of the bottle.

Toutefois, en pratique, de tels bouchons ne permettent pas une utilisation universelle, notamment en raison de la différence de diamètre existant entre les différentes formes de bouteilles utilisées ou bien en fonction du matériau dans lequel sont fabriquées ces bouteilles.However, in practice, such plugs do not not allow universal use, in particular because of the difference in diameter between the different shapes of bottles used or depending on the material from which these bottles are made.

En effet, les dimensions du goulot des différentes bouteilles varient en fonction de la nature du matériau dans lequel elles sont réalisées et, il est à noter des diamètres différents selon qu'il s'agisse de bouteilles en PET perdu ou bien en PET retournable ou bien encore en PVC ou verre, ce qui nécessite l'utilisation de bouchons de dimensions différentes adaptées à chaque type de bouteilles.Indeed, the dimensions of the neck of the different bottles vary according to the nature of the material in which they are made and, it should be noted different diameters depending on whether they are bottles in lost PET or in returnable PET or still in PVC or glass, which requires the use of caps of different sizes adapted to each type of bottle.

On connait également un bouchon qui comporte une coque associée à un joint d'étanchéîté réalisé dans un matériau différent de celui de la coque, ce qui en accroît le coût et rend difficile son recyclage après l'utilisation.A plug is also known which comprises a shell associated with a seal made of a material different from that of the shell, which increases the cost and makes it difficult to recycle after use.

Il est également connu d'utiliser un bouchon fileté pour bouteilles réalisées en matière plastique qui comprend un filetage intérieur et une lèvre d'étanchéité circulaire et élastique venant s'appliquer axialement contre le buvant de la bouteille.It is also known to use a threaded stopper for bottles made of plastic material which includes an internal thread and a circular and elastic sealing lip which is applied axially against the rim of the bottle.

Bien que d'un emploi plus universel, un tel bouchon présente des caractéristiques d'étanchéité insuffisantes, notamment lorsque le liquide placé à l'intérieur de la bouteille est du type pétillant ou sous pression, ce qui est rencontré dans de nombreuses utilisations.Although more universal in use, such a stopper has insufficient sealing characteristics, in particular when the liquid placed inside the bottle is of the sparkling or pressurized type, which is encountered in many uses.

Il est également à noter qu'en raison de la souplesse et de l'élasticité de la lèvre d'étanchéité, celle-ci a tendance à se déformer sous l'action de contraintes ce qui ne fait qu'accroître la perte d'étanchéité de tels bouchons.It should also be noted that due to the flexibility and elasticity of the sealing lip, it tends to deform under the action of stresses which only increases the loss of sealing. such plugs.

Le document DE-U- 92 08 944 décrit un bouchon qui a la forme d'une coque comprenant un plateau et une jupe; la jupe présente un filetage intérieur apte à coopérer avec une partie filetée du col de la bouteille et le plateau porte un anneau d'étanchéité terminé par un épanouissement. Losqu'on visse ce bouchon sur le goulot d'une bouteille, l'anneau s'étend, sans fléchir, à l'intérieur du goulot qui est ainsi serré entre cet anneau et la jupe. Mais ce bouchon présente l'inconvénient de ne pouvoir être monté que sur des bouteilles qui ont des dimensions déterminées.Document DE-U-92 08 944 describes a stopper which has the shape of a shell comprising a tray and a skirt; the skirt has an internal thread capable of cooperating with a threaded part of the neck of the bottle and the plate carries a sealing ring terminated by a development. When this cap is screwed onto the neck of a bottle, the ring extends, without bending, inside the neck which is thus clamped between this ring and the skirt. However, this stopper has the drawback of being able to be mounted only on bottles which have determined dimensions.

En ce qui concerne l'inviolabilité de ces bouchons, différentes techniques ont déjà été imaginées. parmi celles-ci, on peut citer une bague d'inviolabilité assujettie à la base de la coque du bouchon et qui comporte une patte assurant la retenue de cette bague sur la coque après que le bouchon ait été dévissé. Toutefois, celle-ci n'est pas toujours d'un emploi aisé puisqu'il est quelquefois difficile de pouvoir la retirer afin d'en débarrasser le bouchon. Il est également à noter que cette bague n'a pas toujours les caractéristiques suffisantes pour assurer une bonne inviolabilité, ce qui est préjudiciable à son utilisation.Regarding the inviolability of these caps, various techniques have already been devised. among these, there may be mentioned a tamper-evident ring secured to the base of the cap shell and which has a tab ensuring the retention of this ring on the shell after the cap has been unscrewed. However, it is not always easy to use since it is sometimes difficult to be able to remove it in order to clear the plug. It should also be noted that this ring does not always have sufficient characteristics to ensure good inviolability, which is detrimental to its use.

Le bouchon selon l'invention remédie à ces inconvénients car il peut être utilisé quel que soit le type de bouteilles : en PET, en PVC ou en verre, sur des bouteilles dont les dimensions peuvent être différentes de celles prévues à l'origine.The plug according to the invention remedies these disadvantages because it can be used regardless of the type of bottles: PET, PVC or glass, on bottles whose dimensions may be different from those originally planned.

Ce bouchon a la forme d'une coque comprenant un plateau et une jupe, qui présente un filetage intérieur apte à coopérer avec une partie filetée du col de la bouteille, cette coque comportant un anneau d'étanchéité et une bague d'inviolabilité et est caractérisé en ce que l'anneau d'étanchéité comporte à sa périphérie un jonc et est porté par la jupe du bouchon.This stopper has the shape of a shell comprising a plate and a skirt, which has an internal thread capable of cooperating with a threaded part of the neck of the bottle, this shell comprising a sealing ring and a tamper-evident ring and is characterized in that the sealing ring has a ring at its periphery and is carried by the skirt of the plug.

Lorsqu'on visse le bouchon sur le goulot d'une bouteille, le buvant de cette dernière repousse contre le plateau l'anneau d'étanchéité et le jonc. Le jonc est ainsi serré entre le buvant de la bouteille et le plateau du bouchon, ce qui assure l'étanchéité. Si les dimensions des bouteilles sont légèrement différentes de celles initialement prévues, la largeur du bourrelet qui est ainsi serrée, varie mais l'étanchéité reste assurée.When the cap is screwed onto the neck of a bottle, the rim of the latter pushes the sealing ring and the rod against the plate. The rod is thus tightened between the rim of the bottle and the cap tray, which ensures sealing. If the dimensions of the bottles are slightly different from those initially planned, the width of the bead which is thus tightened varies, but the seal remains ensured.

Dans un mode de réalisation préféré de l'invention, la périphérie du plateau porte une lèvre annulaire. Lorsqu'on visse le bouchon cette lèvre s'applique sur la paroi extérieure de l'anneau d'étanchéité, ce qui améliore l'étanchéité.In a preferred embodiment of the invention, the periphery of the plate carries an annular lip. When the cap is screwed on, this lip is applied to the outer wall of the sealing ring, which improves sealing.

L'invention sera mieux comprise à la lecture de la description suivante accompagnée des dessins en annexe parmi lesquels :

  • La Figure 1 est une vue schématique en perspective qui illustre un bouchon conforme à l'invention;
  • La Figure 2 est une vue en coupe radiale de ce bouchon;
  • La Figure 3 est une vue en élévation d'un détail de la bague d'inviolabilité équipant le bouchon;
  • Les Figures 4 et 5 sont des vues en coupe qui montrent la mise en place du même bouchon sur le col de bouteilles.
The invention will be better understood on reading the following description accompanied by the accompanying drawings, among which:
  • Figure 1 is a schematic view in perspective which illustrates a stopper according to the invention;
  • Figure 2 is a radial sectional view of this plug;
  • Figure 3 is an elevational view of a detail of the tamper evident ring fitted to the cap;
  • Figures 4 and 5 are sectional views which show the placement of the same stopper on the bottle neck.

Le bouchon 1 selon l'invention comprend une coque 2 qui présente un plateau 3 et une jupe 3a et est réalisé dans une matière plastique présentant de bonnes propriétés de rigidité, par exemple en polyéthylène ou en polypropylène.The plug 1 according to the invention comprises a shell 2 which has a plate 3 and a skirt 3 a and is made of a plastic material having good rigidity properties, for example made of polyethylene or polypropylene.

La jupe 3a de la coque 2 se prolonge à sa base par une bague d'inviolabilité 20 qui sera décrite plus en détails ultérieurement.The skirt 3 a of the shell 2 is extended at its base by a tamper-evident ring 20 which will be described in more detail later.

La jupe 3a de la coque 2 comporte un anneau d'étanchéité 4 qui s'étend vers l'intérieur et qui présente un jonc 5 à sa périphérie interne.The skirt 3 has the hull 2 comprises a sealing ring 4 which extends inwardly and which has a ring 5 at its inner periphery.

La jupe 3a de la coque 2 comporte un filetage intérieur 8 apte à coopérer avec le filetage extérieur du col du goulot 6 d'une bouteille 7 afin de permettre sa mise en place et sa retenue. Dans la forme de réalisation, ce filetage 8 est constitué par des tronçons de bourrelets arrondis s'étendant sur la périphérie interne de la jupe 3a en dessous de l'anneau d'étanchéité 4.The skirt 3 a of the shell 2 has an internal thread 8 able to cooperate with the external thread of the neck of the neck 6 of a bottle 7 in order to allow its positioning and its retention. In the embodiment, this thread 8 is constituted by sections of rounded beads extending on the inner periphery of the skirt 3 is below the sealing ring 4.

Lorsqu'on visse le bouchon 1 sur le col 6 de la bouteille 7, le buvant 6a de la bouteille repousse l'anneau 4 et le jonc 5 de cet anneau vient s'interposer entre le buvant et le plateau; le jonc est comprimé lors du serrage du bouchon, ce qui assure l'étanchéité. Le jonc est efficace aussi bien lorsque toute la surface du jonc est interposée entre le buvant et le plateau, comme on le voit à la Figure 4 que lorsqu'une partie seulement de cette surface est interposée, comme le montre la Figure 5; un même bouchon peut donc être utilisé avec des bouteilles de dimensions différentes.When the cap 1 is screwed onto the neck 6 of the bottle 7, the rim 6 a of the bottle repels the ring 4 and the rod 5 of this ring comes to be interposed between the rim and the plate; the rod is compressed when the cap is tightened, which ensures sealing. The rod is effective both when the entire surface of the rod is interposed between the rim and the tray, as seen in Figure 4 as when only part of this surface is interposed, as shown in Figure 5; the same stopper can therefore be used with bottles of different dimensions.

A titre d'exemple, avec un même bouchon, on peut ainsi fermer hermétiquement des bouteilles 7, dont le goulot présente un filetage extérieur, notamment de diamètre normalisé "28" selon les normes couramment utilisées, telles que par exemple les normes BPF, MCA, ALCOA, 1716, LEIGHT-WEIGHT. Ces dispositions peuvent être également reprises pour des diamètres différents, tels que par exemple des diamètres de "32" "38" "40" ou autres, en fonction du type de contenant.By way of example, with the same stopper, it is thus possible to hermetically seal bottles 7, the neck of which has an external thread, in particular of standardized diameter "28" according to the standards commonly used, such as for example the BPF, MCA standards. , ALCOA, 1716, LEIGHT-WEIGHT. These provisions can also be used for different diameters, such as for example diameters of "32" "38" "40" or others, depending on the type of container.

La périphérie du plateau 3 présente au moins une lèvre annulaire auxiliaire 10, en regard de l'anneau 4; dans le mode de réalisation représenté, cette lèvre a une forme sensiblement triangulaire.The periphery of the plate 3 has at least one auxiliary annular lip 10, opposite the ring 4; in the embodiment shown, this lip has a substantially triangular shape.

Lors du serrage du bouchon 1 sur le goulot 7, la lèvre 10 presse l'anneau 4 sur le col 6 de la bouteille, au niveau externe du buvant 6a, comme on le voit aux Figures 4 et 5, ce qui accroît l'étanchéité.When tightening the plug 1 on the neck 7, the lip 10 presses the ring 4 on the neck 6 of the bottle, at the outer level of the drink 6 a , as seen in Figures 4 and 5, which increases the seal.

L'étanchéité réalisée est telle qu'elle permet de répondre aux normes imposées par les utilisateurs et notamment qu'elle est suffisante lorsque le fluide contenu à l'intérieur de la bouteille est soumis à des pressions élevées, par exemple de plusieurs bars; le bouchon peut ainsi passer sans dommage les tests imposés selon les procédures en vigueur.The tightness achieved is such that it makes it possible to meet the standards imposed by the users and in particular that it is sufficient when the fluid contained inside the bottle is subjected to high pressures, for example several bars; the plug can thus pass without damage the tests imposed according to the procedures in force.

Pour éviter les déformations non désirées du plateau 3 sous l'action des contraintes, celui-ci comporte un renforcement central 15 polygonal, disposé sensiblement dans sa partie médiane, constitué par un polyèdre, par exemple par une pyramide à base triangulaire faisant saillie perpendiculairement intérieurement.To avoid unwanted deformations of the plate 3 under the action of stresses, the latter comprises a polygonal central reinforcement 15, arranged substantially in its middle part, constituted by a polyhedron, for example by a pyramid with a triangular base projecting perpendicularly internally .

En ce qui concerne la bague d'inviolabilité 20, elle est maintenue à la base de la jupe 3a de la coque 2 par l'intermédiaire de premiers pontets de liaison 21 régulièrement répartis sur sa périphérie. Le nombre et la dimension de ces pontets 21 sont fonction des applications et des besoins et l'on choisit de préférence un nombre et une répartition qui offrent une rigidité suffisante lorsque la bague 20 est solidaire de la jupe 3a tout en permettant une rupture de manière désirée lorsqu'on désire ouvrir la bouteille.As regards the tamper-evident ring 20, it is held at the base of the skirt 3 a of the shell 2 by means of first connecting bridges 21 regularly distributed over its periphery. The number and size of these bridges 21 are based on the applications and needs and is preferably selected a number and distribution that provide sufficient rigidity when the ring 20 is secured to the skirt 3 has while allowing a break desired way when you want to open the bottle.

Par ailleurs, ces pontets de liaison 21 permettent au cours de la mise en place du bouchon, d'obtenir un posiitionnement adapté de l'anneau d'étanchéité 4 sur le corps 6 de la bouteille sans qu'il se rompe ou se casse.Furthermore, these connecting bridges 21 allow during the establishment of the stopper, to obtain a suitable positioning of the sealing ring 4 on the body 6 of the bottle without it breaking or breaking.

La bague 20 comporte par ailleurs, comme plus particulièrement montrée à la Figure 3, une fente inclinée 22 dont l'inclinaison et l'angle sont déterminés pour permettre la rupture de la bague 20 par l'intermédiaire de deux seconds pontets de liaison 22a-22b lorsqu'on désire ouvrir la bouteille et ôter le bouchon 1. L'inclinaison de la fente 22 répartit les contraintes séquentiellement pendant la première mise en place du bouchon avec sa bague 20 sur le col de la bouteille.The ring 20 also comprises, as more particularly shown in FIG. 3, an inclined slot 22 whose inclination and angle are determined to allow the rupture of the ring 20 by means of two second connecting bridges 22a- 22b when it is desired to open the bottle and remove the cap 1. The inclination of the slot 22 distributes the stresses sequentially during the first fitting of the cap with its ring 20 on the neck of the bottle.

Une languette de rupture 23 est également prévue entre la coque 2 et la bague 20; après l'ouverture de la bague 20, cette languette assure un maintien local sur la coque 2, au niveau de la jupe 3a. Les dimensions de la languette 23 sont telles qu'elles permettent facilement, si on le désire, le retrait de celle-ci de la jupe 3a, notamment lorsqu'on réutilise le bouchon, après l'utilisation d'une partie du produit, pour le remettre sur le col 6 de la bouteille.A rupture tab 23 is also provided between the shell 2 and the ring 20; after the opening of the ring 20, this tongue provides local support on the shell 2, at the level of the skirt 3 a . The dimensions of the tongue 23 are such that they allow easily, if desired, the withdrawal of the latter from the skirt 3 a , in particular when the plug is reused, after the use of part of the product, to put it back on the neck 6 of the bottle.

La bague 20 comporte également des bourrelets d'accrochage 24 régulièrement répartis sur sa périphérie intérieure et qui se présentent sous la forme de tronçons inclinés aptes à coopérer avec le col 6 de la bouteille pour assurer un maintien efficace de celui-ci en position désirée.The ring 20 also includes hooking beads 24 regularly distributed over its inner periphery and which are in the form of inclined sections capable of cooperating with the neck 6 of the bottle to ensure effective retention of the latter in the desired position.

Pour éviter la détérioration de cette bague 20 pendant la première mise en place du bouchon sur la bouteille, elle comporte régulièrement répartie sur sa périphérie externe des plots de renfort internes 25. Ces plots de renfort 25 sont, par exemple, constitués par des troncs de cône dont la partie la plus large 26 se trouve au niveau de la base 27 de la jupe 3a de manière qu'ils puissent venir en appui sur la coque du bouchon contre la jupe, lors du vissage par des machines de conditionnement. Par ailleurs, ces plots augmentent la protection contre les possibilités d'ouverture non désirées du bouchon, en renforçant la résistance à l'étirement de la bague 20.To avoid deterioration of this ring 20 during the first fitting of the stopper on the bottle, it has regularly distributed on its external periphery internal reinforcement pads 25. These reinforcement pads 25 are, for example, constituted by trunks of cone whose widest part 26 is located at the base 27 of the skirt 3 was such that they can bear against the shell of the stopper against the skirt when screwing by packaging machines. Furthermore, these studs increase the protection against the unwanted possibilities of opening the stopper, by increasing the resistance to stretching of the ring 20.

Lors de l'ouverture de ce bouchon, sous l'action du dévissage, les bourrelets d'accrochage 24 viennent dans une position de butée contre une contre-bague du col 6 de la bouteille et les contraintes mécaniques transmises en continuant de dévisser sont transmises dans la bague 20 de façon à obtenir la rupture des pontets de liaison 21 et des pontets 22a-22b autorisant l'ouverture du bouchon.During the opening of this cap, under the action of unscrewing, the attachment beads 24 come into a stop position against a counter-ring of the neck 6 of the bottle and the mechanical stresses transmitted while continuing to unscrew are transmitted in the ring 20 so as to obtain the rupture of the connecting bridges 21 and the bridges 22 a -22 b authorizing the opening of the plug.

On voit de la description qui précède que le bouchon selon l'invention

  • peut être utilisé quel que soit le type de bouteilles et avec une certaine tolérance dans les dimensions du col de la bouteille;
  • présente une rigidité suffisante pour éviter une déformation, ce qui favorise le conditionnement des bouteilles, notamment en lots;
  • le couple de dévissage est stable, malgré l'étanchéité obtenue, grâce à un frottement plus faible lors du dévissage, par rapport aux bouchons usuels à lèvre;
  • il facilite le dégazage lorsque la bouteille contient un fluide pétillant. En effet, le dégazage commence par un faible angle d'ouverture du bouchon, la partie du bouchon au contact du goulot de la bouteille restant importante: cela assure une bonne sécurité pour le consommateur en évitant l'arrachement du bouchon du col de la bouteille.
It can be seen from the above description that the stopper according to the invention
  • can be used whatever the type of bottles and with a certain tolerance in the dimensions of the neck of the bottle;
  • has sufficient rigidity to avoid deformation, which promotes the packaging of bottles, especially in batches;
  • the unscrewing torque is stable, despite the seal obtained, thanks to a lower friction during unscrewing, compared to the plugs usual lip;
  • it facilitates degassing when the bottle contains a sparkling fluid. In fact, degassing begins with a small opening angle of the stopper, the part of the stopper in contact with the neck of the bottle remaining large: this ensures good safety for the consumer by avoiding the tearing of the stopper from the neck of the bottle. .

Bien entendu, l'invention n'est pas limitée à la seule forme de réalisation qui a été décrite ci-dessus mais au contraire elle en embrasse toutes les variantes de réalisation.Of course, the invention is not limited to the single embodiment which has been described above but on the contrary it embraces all the variant embodiments thereof.
