Description

Bouchon de matière synthétique.  Cap of synthetic material.
La présente invention concerne un bouchon de matière synthétique plastique, par exemple en PE, apte à être vissé sur le col d'un récipient pour en obturer l'ouverture. The present invention relates to a plug of plastic synthetic material, for example PE, adapted to be screwed onto the neck of a container to close the opening.
Quoique non exclusivement, le bouchon de matière synthétique selon l'invention est particulièrement approprié à obturer des récipients contenant des sodas, des eaux minérales, etc.  Although not exclusively, the plastic stopper according to the invention is particularly suitable for closing containers containing soda, mineral water, etc.
On connaît déjà un bouchon de matière synthétique en forme de capuchon destiné à être monté sur le col d'un récipient par vissage et comportant une paroi circulaire de bouchage portée par le fond du bouchon et apte à pénétrer dans ledit col, ainsi qu'une bague de sécurité reliée audit bouchon par une ligne de prédécoupe et audit col par des moyens de retenue. Pour ouvrir un récipient équipé d'un tel bouchon, on dévisse ce dernier, la course du dévissage permettant de briser la liaison au niveau de la prédécoupe entre la bague de sécurité et le bouchon, et d'extraire ladite paroi circulaire de bouchage hors du col du récipient.  A cap-shaped plastic cap is already known which is to be mounted on the neck of a container by screwing and having a circular closure wall carried by the bottom of the cap and able to penetrate into said neck, as well as a safety ring connected to said plug by a precut line and neck audit by retaining means. To open a container equipped with such a cap, it unscrews the latter, the unscrewing stroke to break the connection at the pre-cut between the safety ring and the cap, and to extract said circular closure wall out of the container neck.
Bien entendu, pour qu'un tel bouchon assure correctement sa fonction, il est indispensable que la paroi circulaire de bouchage exerce un frottement serré sur le col du récipient et que la liaison réalisée par la ligne de prédécoupe soit suffisamment forte.  Of course, for such a plug to properly perform its function, it is essential that the circular closure wall exerts a tight friction on the neck of the container and that the connection made by the precut line is sufficiently strong.
Par suite, l'effort d'entraînement que doit exercer le bouchon lors du dévissage doit être important pour permettre la rupture de la ligne de découpe et pour extraire la paroi circulaire de bouchage du col du récipient.  As a result, the drive force that must exert the cap during unscrewing must be important to allow the breaking of the cutting line and to extract the circular closure wall of the neck of the container.
Pour qu'un opérateur manuel puisse exercer sur le bouchon un couple suffisant pour engendrer le débouchage, il est donc nécessaire que la prise dudit bouchon par ledit opérateur soit suffisamment forte et commode.  In order for a manual operator to be able to exert on the stopper a sufficient torque to cause unclogging, it is therefore necessary for the plug to be taken by said operator to be sufficiently strong and convenient.
Or, notamment pour des considérations économiques, il n'est pas rare que la surface extérieure de préhension dudit bouchon soit trop petite pour permettre une prise manuelle satisfaisante et un débouchage aisé. De plus, du fait de la petitesse de la surface extérieure de préhension, l'utilisateur peut être amené à serrer involontairement la bague de sécurité, ce qui augmente encore les difficultés de débouchage. However, especially for economic reasons, it is not uncommon for the outer gripping surface of said plug is too small to allow a satisfactory manual grip and easy unclogging. Moreover, because of the smallness of the outer gripping surface, the user can to unintentionally tighten the safety ring, which further increases the difficulties of unclogging.
La présente invention a pour objet de remédier à cet inconvénient sans pour cela augmenter de façon sensible le coût du bouchon.  The present invention aims to overcome this disadvantage without significantly increasing the cost of the plug.
À cette fin, selon l'invention, le bouchon de matière synthétique en forme de capuchon, destiné à être monté sur le col d'un récipient par vissage et comportant une paroi circulaire de bouchage interne portée par le fond dudit bouchon et apte à pénétrer dans ledit col, ainsi qu'une bague de sécurité reliée audit bouchon par une ligne de prédécoupe et audit coi par des moyens de retenue, est remarquable en ce que la partie dudit fond qui se trouve en correspondance avec la paroi circulaire de bouchage interne est extérieurement rehaussée pour augmenter la surface extérieure de préhension dudit bouchon.  To this end, according to the invention, the synthetic cap in the form of a cap, intended to be mounted on the neck of a container by screwing and having a circular inner closure wall carried by the bottom of said cap and able to penetrate in said neck, as well as a safety ring connected to said plug by a precut line and said audit by means of retaining means, is remarkable in that the part of said bottom which is in correspondence with the circular internal closure wall is externally raised to increase the outer gripping surface of said cap.
Ainsi, grâce à la présente invention, on obtient un bouchon dans lequel la surface de préhension est augmentée du rehaussement extérieur dudit fond, alors que, par rapport au bouchon connu, seule la paroi latérale de rehaussement constitue une dépense supplémentaire de matière synthétique. On remarquera de plus que, grâce à l'invention, la cavité délimitée par la paroi circulaire de bouchage interne et la cavité délimitée par le rehaussement extérieur du fond s'additionnent alors pour former une grande cavité unique à paroi lisse.  Thus, by virtue of the present invention, a plug is obtained in which the gripping surface is increased by the external raising of said bottom, whereas, with respect to the known plug, only the side wall of raising constitutes an additional expense of synthetic material. It will be further noted that, thanks to the invention, the cavity delimited by the circular internal closure wall and the cavity delimited by the external enhancement of the bottom then add up to form a large single cavity with a smooth wall.
Afin d'augmenter la qualité de la préhension, le retrait circulaire formé entre la partie rehaussée et la partie non rehaussée peut comporter des aspérités de préhension, par exemple des ailettes diamétrales solidaires des parois dudit retrait.  In order to increase the quality of the grip, the circular shrinkage formed between the raised portion and the non-raised portion may include gripping asperities, for example diametrical fins secured to the walls of said shrinkage.
Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée. Sur ces figures, des références identiques désignent des éléments semblables.  The figures of the appended drawing will make it clear how the invention can be realized. In these figures, identical references designate similar elements.
La figure 1 est une vue en coupe axiale schématique d'un bouchon connu que la présente invention permet de perfectionner. Les figures 2 et 3 sont respectivement une vue de face et une vue de dessus d'un mode de réalisation du bouchon selon l'invention. Figure 1 is a schematic axial sectional view of a known plug that the present invention can be improved. Figures 2 and 3 are respectively a front view and a top view of an embodiment of the plug according to the invention.
Les figures 4 et 5 sont des coupes diamétrales du bouchon des figures 2 et 3, respectivement selon les lignes IV-IV et V-V de cette dernière figure.  Figures 4 and 5 are diametrical sections of the cap of Figures 2 and 3 respectively along the lines IV-IV and V-V of the latter figure.
Les figures 6 et 7 sont des vues en perspective, respectivement du dessus et du dessous du bouchon des figures 2 et 3.  Figures 6 and 7 are perspective views, respectively from above and below the cap of Figures 2 and 3.
Sur la figure 1 , on a représenté schématiquement en coupe diamétrale un bouchon de matière synthétique connu 1 , en forme de capuchon, monté sur le col 3 d'un récipient 4 pour en obturer l'ouverture. Le bouchon 1 est vissable sur le col 3 grâce à des filets 5 et il comporte une paroi circulaire de bouchage interne 6 portée par le fond 2 et apte à pénétrer dans ledit col 3.  In Figure 1, there is shown schematically in diametral section a plug of known synthetic material 1, in the form of a cap, mounted on the neck 3 of a container 4 to close the opening. The cap 1 is screwed onto the neck 3 by means of threads 5 and it comprises a circular internal closure wall 6 carried by the bottom 2 and able to penetrate into said neck 3.
De plus, le bouchon 1 comporte une bague de sécurité 7, reliée à la partie inférieure du bouchon 1 par une ligne de prédécoupe 8.  In addition, the stopper 1 comprises a safety ring 7, connected to the lower part of the stopper 1 by a precut line 8.
En position d'obturation (celle représentée sur la figure 1), le bouchon 1 est vissé au maximum dans le col 3, avec la paroi circulaire 6 de bouchage interne d'étanchéité enfoncée à fond dans celui-ci et la bague de sécurité 7 maintenue sur ledit col 3 grâce à un système connu de bossages 9 (non représentés sur la figure 1 , mais identiques à ceux visibles sur les figures 4 à 7), coopérant avec des bossages de retenue portés par ledit col 3 (non représentés).  In the closed position (that shown in Figure 1), the cap 1 is screwed to the maximum in the neck 3, with the circular wall 6 of sealing internal closure fully pressed into it and the safety ring 7 maintained on said neck 3 by means of a known system of bosses 9 (not shown in Figure 1, but identical to those shown in Figures 4 to 7), cooperating with retaining bosses carried by said neck 3 (not shown).
Ainsi, pour déboucher le récipient 4, il faut dévisser le bouchon et exercer sur celui-ci un couple suffisamment important pour briser la ligne de prédécoupe 8 et vaincre la friction de la paroi de bouchage interne 6 dans le col 3 du récipient. Bien entendu, pour pouvoir exercer ce couple, il est nécessaire que la main de l'opérateur ait une prise correcte sur le bouchon 1 , ce qui n'est pas toujours ie cas. il en résulte des difficultés et des efforts pour l'opérateur désirant ouvrir le récipient 1.  Thus, to unclog the container 4, it is necessary to unscrew the stopper and exert on it a sufficiently large torque to break the pre-cut line 8 and overcome the friction of the internal closure wall 6 in the neck 3 of the container. Of course, to be able to exercise this torque, it is necessary that the hand of the operator has a correct grip on the cap 1, which is not always the case. this results in difficulties and efforts for the operator wishing to open the container 1.
Pour remédier à ces inconvénients, dans le bouchon 10, conforme à l'invention, représenté sur les figures 2 à 7 et comportant les éléments 5 à 8 décrits en regard de la figure 1 (voir principalement la figure 4), la partie du fond 2 qui se trouve en correspondance avec la paroi circulaire 6 de bouchage interne est extérieurement rehaussée (2A). Ainsi, le fond du bouchon 10 comporte maintenant ladite partie rehaussée 2A et une partie périphériqueTo overcome these drawbacks, in the plug 10, according to the invention, shown in Figures 2 to 7 and having the elements 5 to 8 described with reference to Figure 1 (see mainly Figure 4), the part of the bottom 2 which is in correspondence with the circular wall 6 of internal closure is externally raised (2A). Thus, the bottom of the plug 10 now comprises said raised portion 2A and a peripheral portion
2B. 2B.
La surface extérieure du bouchon 10 est donc supérieure à celle du bouchon 1 , de sorte que la prise manuelle du bouchon 10 est augmentée et que l'application du couple de débouchage est plus aisée, sans pour cela que la masse de matière utilisée pour fabriquer le bouchon soit sensiblement supérieure.  The outer surface of the plug 10 is therefore greater than that of the plug 1, so that the manual plug 10 is increased and that the application of the unclogging torque is easier, without that the mass of material used to manufacture the cap is substantially greater.
À l'intérieur du bouchon 10 est formée une unique grande cavité 11 à paroi lisse, constituée par la somme de la cavité 12 délimitée par la paroi circulaire de bouchage interne 6 et de la cavité 13 engendrée par le rehaussement de la partie 2A du fond 2.  Inside the plug 10 is formed a single large cavity 11 with a smooth wall, constituted by the sum of the cavity 12 delimited by the circular inner closure wall 6 and the cavity 13 generated by the raising of the bottom portion 2A. 2.
Pour améliorer la préhension du bouchon 10, des aspérités de préhension 14 sont disposées dans le retrait circulaire 15 entre la partie rehaussée 2A et la partie non rehaussée 2B du fond 2. De telles aspérités de préhension peuvent être des ailettes diamétrales solidaires des parois du retrait  To improve the gripping of the plug 10, the gripping asperities 14 are arranged in the circular recess 15 between the raised portion 2A and the non-raised portion 2B of the bottom 2. Such gripping asperities may be diametrical fins integral with the walls of the recess.
