Abstract

The invention is a cap with no attached seal to seal the opening at the mouth of a container. This cap comprises a closure disc around which there is a peripheral skirt sized to fit around the mouth of the container. It also comprises a first circular lip which projects under the closure disc near the mouth opening and which is folded against the mouth of the container towards the opening thereof when the cap is in place, thus preventing any surf effect when the container is moved around. The cap also comprises a circular second lip external to the first and positioned also to be folded against the mouth of the container in the opposite direction to that of the first lip when the cap is in place. This second lip, which projects under the closure disc around the first lip, is provided with a number of protrusions positioned such as to form a number of points of contact with the mouth of the container when the second lip is in the folded position and thus form a number of sealing barriers with a staircase effect. The protrusions, by hugging the shape of the mouth of the container, absorb any surface defects or scratches due to imperfections in the manufacture or accidents in handling.

Description

BOUCHON SANS JOINT RAPPORTE CAP WITHOUT JOINT REPORTS
La présente invention a pour objet un bouchon sans joint rapporté utilisable pour fermer et étancher l'ouverture du goulot d'un contenant, telle qu'une bonbonne de liquide.The present invention relates to a plug without added seal used to close and seal the opening of the neck of a container, such as a bottle of liquid.
Par "bouchon sans joint rapporté", on entend un bouchon qui permet de fermer de façon étanche l'ouverture du goulot d'un contenant notamment de liquide, sans avoir nécessairement besoin d'un joint d'étanchéité habituellement constitué d'un disque de mousse se plaçant sous l'opercule du bouchon, ou alternativement d'un cordon injecté ou moulé agissant comme joint torique. Pour recevoir ce type de joint, les bouchons existants peuvent être pourvus d'une gorge disposée en dessous de l'opercule où vient se loger le joint. La pression exercée par l'anneau de tension ou le système d'accrochage lors du montage du bouchon comprime le joint sur la surface supérieure de l'ouverture du goulot et assure ainsi l'étanchéité voulue.By "plug without added seal" is meant a plug which makes it possible to seal the opening of the neck of a container, in particular of liquid, without necessarily needing a seal usually consisting of a disc of foam placed under the lid of the cap, or alternatively an injected or molded bead acting as an O-ring. To receive this type of seal, the existing plugs may be provided with a groove disposed below the seal where the seal is housed. The pressure exerted by the tension ring or the attachment system during the mounting of the cap compresses the seal on the upper surface of the opening of the neck and thus ensures the desired seal.
Tel que précédemment mentionné, la présente invention a pour objet un bouchon qui assure une excellente étanchéité sans pour autant avoir un tel joint rapporté.As previously mentioned, the present invention relates to a cap which provides excellent sealing without having such a reported seal.
Il existe déjà des bouchons sans joint rapporté. A titre d'exemples non limitatifs ou peut se référer aux brevets américains suivants: US 3.325.033 (WEATON) de 1967;There are already caps without reported seal. As non-limiting examples or can refer to the following US patents: US 3,325,033 (WEATON) 1967;
US 3.815.771 (MARKS) de 1974;US 3,815,771 (MARKS) of 1974;

US 4.905.852 (ZUMBUHL) de 1990. Les brevets en question décrivent des bouchons qui ne nécessitent pas de joint rapporté dans la mesure où ils sont pourvus de lèvres circulaires, de dents et/ou de protubérances qui se trouvent sous l'opercule axialement au col du bouchon ou sur la jupe périphérique de celui-ci en vue de venir prendre appui à même le goulot et ainsi obtenir l'étanchéité désirée. Les bouchons en question sont bien entendu destinés à venir s'accrocher à même des retraits spécifiquement prévus à cet effet dans la partie externe du goulot.US 4,905,852 (ZUMBUHL) of 1990. The patents in question disclose plugs which do not require an inserts seal provided they are provided with circular lips, teeth and / or protuberances which are located under the cover axially at the neck of the plug or on the peripheral skirt of the plug. it in order to come to bear on the neck and thus get the desired seal. The plugs in question are of course intended to hang on even withdrawals specifically provided for this purpose in the outer portion of the neck.
Si tous les bouchons sans joint rapporté connus de la Demanderesse semblent a priori fonctionner, il n'en demeure pas moins qu'il existe un problème lorsque le contenant que l'on cherche à fermer est gros, comme c'est le cas des bonbonnes d'eau de 3, 4 et 5 gallons telles que celles utilisées en position renversée dans des fontaines de distribution. Avec ce genre de bonbonnes, il est en effet difficile d'obtenir une bonne étanchéité, notamment lors de leur transport. Il est également difficile d'obtenir un bon effet d'imperméabilité, d'étanchéité et d'herméticité pour assurer un maintien de la pureté initiale du contenu. Le bon effet d'imperméabilité est important pour assurer le maintien de la pureté initiale du contenu. L'utilisation de bouchons faits d'une seule matière, Wz. sans joint, est également importante pour atteindre cet effet. On peut comprendre ici que les manutentions de stockage ou de livraison provoquent un mouvement de l'eau ou tout autre liquide stocké dans la bonbonne, ce qui peut créer un véritable effet de ressac. Par ailleurs, la bonbonne une fois placée sur la fontaine usuellement en position renversée, crée une pression qui s'exerce sur le bouchon du fait que le liquide qui s'écoule est remplacé par de l'air dont la pression assure un transfert par gravité. L'action de l'atmosphère exerce également une pression extérieure variable suivant les conditions météorologiques (température, pression). C'est le difficile équilibrage entre pression interne et pression externe qui doit soustraire le bouchon au risque de fuite. La présente invention a pour objet un bouchon sans joint rapporté qui permet de répondre à tous les besoins ci-dessus évoqués en terme d'imperméabilité, étanchéité et effet hermétique.If all the plugs without reported joint known to the Applicant seem a priori work, it remains nonetheless that there is a problem when the container that is trying to close is big, as is the case of the bottles 3, 4 and 5 gallon water such as those used in the inverted position in dispensing fountains. With this kind of bottles, it is indeed difficult to obtain a good seal, especially during transport. It is also difficult to obtain a good effect of impermeability, sealing and hermeticity to maintain the initial purity of the contents. The good imperviousness effect is important to maintain the original purity of the contents. The use of plugs made of a single material, Wz. seamless, is also important to achieve this effect. It can be understood here that handling storage or delivery causes a movement of water or any other liquid stored in the cylinder, which can create a real effect surf. Moreover, the bottle once placed on the fountain usually in the inverted position, creates a pressure exerted on the cap because the liquid that flows is replaced by air whose pressure ensures a transfer by gravity . The action of the atmosphere also exerts a variable external pressure according to the meteorological conditions (temperature, pressure). It is the difficult balancing between internal pressure and external pressure that must subtract the cap from the risk of leakage. The present invention relates to a plug without attached insert that meets all the needs mentioned above in terms of impermeability, sealing and hermetic effect.
Le bouchon sans joint rapporté selon l'invention pour fermer une ouverture de goulot d'un contenant comprend, comme éléments de base:The sealless plug according to the invention for closing a neck opening of a container comprises, as basic elements:
- un opercule de fermeture;- a closing cap;
- une jupe périphérique dimensionnée pour s'emboîter autour du goulot, cette jupe ayant une surface interne pourvue de moyens d'attache capables de s'engager à même le goulot et ainsi pouvoir assurer l'accrochage du bouchon à même le goulot;- A peripheral skirt sized to fit around the neck, this skirt having an inner surface provided with fastening means capable of engaging the same neck and thus be able to ensure the attachment of the plug to the same neck;
- une première lèvre circulaire qui se trouve en saillie sous l'opercule de fermeture à proximité de l'ouverture du goulot, cette première lèvre se trouvant pliée contre le goulot vers l'ouverture de celui-ci lorsque le bouchon est fixé et permettant ainsi d'éviter tout effet de ressac lorsque le contenant est déplacé; eta first circular lip which is projecting under the closing cap near the opening of the neck, this first lip being folded against the neck towards the opening thereof when the stopper is fixed and thus allowing avoid any surfing effect when the container is moved; and
- une seconde lèvre circulaire externe à la première et positionnée pour être elle aussi pliée contre le goulot dans une direction opposée à celle de la première lèvre lorsque le bouchon est fixé.- A second outer circular lip to the first and positioned to be also folded against the neck in a direction opposite to that of the first lip when the cap is fixed.
La combinaison de ces éléments de base dans un bouchon sans joint rapporté est déjà connue en soi, comme le confirme à titre non limitatif, le contenu des brevets américains US 4.416.383; 4.645.088 et US 4.905.852, ci-dessus mentionnés.The combination of these basic elements in a plug without reported seal is already known per se, as confirmed by way of non-limiting, the contents of US Patents US 4,416,383; 4,645,088 and US 4,905,852, mentioned above.
Le bouchon selon la présente invention se distingue toutefois des bouchons existants en ce que sa seconde lèvre est elle aussi en saillie sous l'opercule de fermeture autour de la première lèvre, et est en outre pourvue de plusieurs dents ou protubérances positionnées pour former plusieurs points de contact avec le goulot lorsque la seconde lèvre est en position pliée et ainsi former plusieurs barrières d'étanchéité avec un effet d'escalier. Les dents ou protubérances épousent ainsi la forme du goulot et absorbe les défauts et rayures de surfaces dues à des imperfections de fabrication ou des accidents de manutention.The plug according to the present invention is however distinguished from existing plugs in that its second lip is also projecting under the closure cap around the first lip, and is further provided with several teeth or protuberances positioned to form several points contact with the neck when the second lip is in the folded position and thus form several sealing barriers with a staircase effect. The teeth or protuberances thus marry the shape of the neck and absorbs the defects and surface scratches due to manufacturing imperfections or handling accidents.
Il convient de mentionner que l'utilisation de petites dents ou protubérances dans un bouchon est déjà connue en soi, comme l'atteste à titre d'exemples non limitatifs les brevets américains US 3.325.033; US 4.106.653 etIt should be mentioned that the use of small teeth or protuberances in a stopper is already known per se, as attested by way of non-limiting examples, US Pat. No. 3,325,033; US 4,106,653 and
US 4.884.707, ci-dessus mentionnée. Toutefois, dans ces brevets existants, les dents ou protubérances ne sont pas positionnées à même une lèvre repliable mais directement à même la surface interne du bouchon, ce qui ne donne pas du tout le même effet. Elles agissent en effet comme joints complémentaires.US 4,884,707, above mentioned. However, in these existing patents, the teeth or protuberances are not positioned in a collapsible lip but directly on the inner surface of the cap, which does not give the same effect at all. They act indeed as complementary joints.
On comprendra ici que le fait d'avoir des dents ou protubérances sur une lèvre permet par l'effet ressort (ou voir souplesse) de l'ensemble lèvres plus dents et/ou protubérances, d'obtenir un contact différent sur le col des bonbonnes ou contenants.It will be understood here that the fact of having teeth or protuberances on a lip allows by the spring effect (or see flexibility) of the set of lips plus teeth and / or protuberances, to obtain a different contact on the neck of the bottles or containers.
Selon une caractéristique préférentielle de l'invention, les première et seconde lèvres sont réunies par une zone plus épaisse pour renforcer leur rigidité et ainsi les rendre moins flexibles, ce qui les amène à se plier avec plus de pression sur le goulot et assurer un effet de coupe de succion.According to a preferred feature of the invention, the first and second lips are joined by a thicker zone to reinforce their rigidity and thus make them less flexible, which causes them to bend with more pressure on the neck and ensure an effect. suction cup.
Selon une autre caractéristique préférentielle de l'invention, l'opercule a une surface inférieure pourvue d'une dépression circulaire formant une gorge adjacente à la première lèvre. Cette gorge donne aussi un espace de repli à la première lèvre, ce qui assure ainsi un reflux plus facile en cas de ressac et donc une meilleure efficacité et étanchéité.According to another preferred feature of the invention, the cap has a lower surface provided with a circular depression forming a groove adjacent to the first lip. This groove also gives a space for folding in the first lip, which thus ensures easier backflow in case of surf and therefore better efficiency and sealing.
De préférence encore, la jupe périphérique a une partie supérieure interne pourvue d'une rainure formant, de par sa position, une troisième lèvre externe aux deux autres, cette troisième lèvre applique une pression sur le bouchon lorsque celui-ci est fixé au goulot et assure ainsi un meilleur serrage de l'anneau de tension du bouchon contre le bourrelet du goulot, avec en outre une compression maximale des première et seconde lèvres en position pliée et un point de contact supplémentaire avec le goulot.More preferably, the peripheral skirt has an inner upper portion provided with a groove forming, by its position, a third outer lip to the other two, this third lip applies a pressure on the cap when it is attached to the neck and thus ensures a better tightening of the tension ring of the stopper against the bead of the neck, with furthermore maximum compression of the first and second lips in the folded position and an additional point of contact with the neck.
Comme il est de pratique habituelle, la jupe du bouchon selon l'invention est avantageusement pourvue d'une patte de traction associée à un mince de déchirement pour faciliter son retrait. Le bouchon est également avantageusement injecté en une seule pièce en matière plastique.As is customary, the skirt of the cap according to the invention is advantageously provided with a pull tab associated with a thin tear to facilitate its removal. The cap is also advantageously injected in one piece of plastic material.
Les divers avantages de la présente invention ainsi que son fonctionnement sont mieux compris à la lecture de la description non limitative qui suit d'un mode de réalisation préféré de l'invention, faite en se référant aux dessins annexés dans lesquels:The various advantages of the present invention as well as its operation are better understood on reading the nonlimiting description which follows of a preferred embodiment of the invention, with reference to the appended drawings in which:
La figure 1 est une vue en perspective de dessous d'un bouchon sans joint rapporté selon un mode de réalisation préféré de l'invention;Figure 1 is a perspective view from below of a plug without reported seal according to a preferred embodiment of the invention;
La figure 2 est une vue en coupe partielle du bouchon illustré sur la figure 1 lorsque celui-ci est placé pour fins d'installation sur le goulot d'un contenant;Figure 2 is a partial sectional view of the cap shown in Figure 1 when it is placed for installation on the neck of a container;
La figure 3 est une vue similaire à la figure 2, montrant le bouchon lorsque celui-ci est partiellement enfoncé; etFigure 3 is a view similar to Figure 2, showing the plug when the latter is partially depressed; and
La figure 4 est une vue similaire aux figures 2 et 3, montrant le bouchon lorsque celui-ci est totalement installé sur le goulot du contenant.Figure 4 is a view similar to Figures 2 and 3, showing the cap when it is fully installed on the neck of the container.
Le bouchon 1 sans joint rapporté, le mode de réalisation préféré de l'invention illustré dans les dessins annexés, est destiné à fermer l'ouverture du goulot 2 d'un contenant tel que par exemple, une bonbonne d'eau utilisable en position renversée dans une fontaine de distribution. Comme il est de pratique habituelle, le bouchon 1 comprend un opercule de fermeture 3 autour duquel se projette une jupe 5 dimensionnée pour s'emboîter autour du goulot 3. La jupe 5 a une surface interne pourvue de moyens d'attache au goulot illustré, qui, dans le mode de réalisation consistent en un anneau de tension 7 positionné pour pouvoir s'engager sous un bourrelet 9 formé à même le goulot pour pouvoir ainsi assurer la fixation du bouchon à même le goulot. La façon dont l'anneau de tension 7 se trouve placé sous le bourrelet 9 du goulot pour ainsi maintenir le bouchon en position fermée est illustrée plus précisément sur la figure 4.The plug 1 without attached, the preferred embodiment of the invention illustrated in the accompanying drawings, is intended to close the opening of the neck 2 of a container such as for example, a water bottle usable in reverse position in a fountain of distribution. As is customary, the stopper 1 comprises a closure cap 3 around which a skirt 5 sized to fit around the neck 3 projects. The skirt 5 has an internal surface provided with attachment means to the illustrated neck, which in the embodiment consists of a tension ring 7 positioned to be able to engage under a bead 9 formed in the same neck so as to ensure the fixing of the cap on the neck. The manner in which the tension ring 7 is placed under the bead 9 of the neck so as to hold the cap in the closed position is illustrated more precisely in FIG. 4.
On comprendra ici qu'au lieu d'un anneau de tension 7, on peut utiliser d'autres types de moyens d'attache, tels qu'un système de vissage.It will be understood here that instead of a tension ring 7, it is possible to use other types of attachment means, such as a screwing system.
Le bouchon 1 comprend également une première lèvre circulaire 11 qui se trouve en saillie sous l'opercule 3 de fermeture à proximité de l'ouverture du goulot. Cette première lèvre se trouve en pratique pliée contre le goulot vers l'ouverture de celui-ci lorsque le bouchon est fixé, tel que cela se trouve illustré là encore sur la figure 4. Dans cette position pliée, la première lèvre 11 permet d'éviter tout effet de ressac lorsque le contenant est déplacé.The stopper 1 also comprises a first circular lip 11 which is projecting under the closing cap 3 near the opening of the neck. This first lip is in practice folded against the neck towards the opening thereof when the cap is fixed, as is illustrated here again in FIG. 4. In this folded position, the first lip 11 makes it possible to avoid any surfing effect when the container is moved.
Le bouchon comprend également une seconde lèvre circulaire 13 qui est externe à la première et positionnée pour se trouver elle aussi pliée contre le goulot dans une direction opposée à celle de la première lèvre lorsque le bouchon est fixé. La position pliée de la seconde lèvre, une fois le bouchon installé, est là encore clairement illustrée sur la figure 4.The cap also includes a second circular lip 13 which is external to the first and positioned to be also folded against the neck in a direction opposite to that of the first lip when the cap is attached. The folded position of the second lip, once the cap is installed, is again clearly illustrated in FIG. 4.
Cette structure de base du bouchon 1 est déjà connue en soi, tel que cela a déjà été mentionné dans le préambule de la description.This basic structure of the plug 1 is already known per se, as already mentioned in the preamble of the description.
En fait, la présente invention est principalement caractérisée en ce que la seconde lèvre 13 est elle-même placée en saillie directement sous l'opercule de fermeture 3 autour de la première lèvre et est en outre pourvue de plusieurs dents ou protubérances 15 positionnées pour former plusieurs points de contact avec la surface du goulot 9 lorsque la seconde lèvre 13 est en position pliée. Ceci permet ainsi de former plusieurs barrières d'étanchéité avec un effet d'escalier. En outre, les dents ou protubérances 15 en épousant la forme du goulot absorbent les défauts et/ou rayures de surface dues à des imperfections de fabrication ou à des accidents de manutention.In fact, the present invention is mainly characterized in that the second lip 13 is itself projecting directly under the closing cap 3 around the first lip and is further provided with a plurality of teeth or protuberances 15 positioned to form several points of contact with the surface of the neck 9 when the second lip 13 is in the folded position. This makes it possible to form several sealing barriers with a staircase effect. In addition, the teeth or protuberances conforming to the shape of the neck absorb defects and / or surface scratches due to manufacturing imperfections or handling accidents.
Selon une autre caractéristique importante de l'invention, les première et seconde lèvres 11 et 13 sont réunies par une zone plus épaisse, ce qui permet de renforcer leur rigidité et ainsi les rendre moins flexibles. Ceci les amène donc à se plier avec plus de pression, à conserver un effet de ressort sur le goulot et assurer un effet de coupe de succion.According to another important characteristic of the invention, the first and second lips 11 and 13 are joined by a thicker zone, which makes it possible to reinforce their rigidity and thus make them less flexible. This causes them to bend with more pressure, retain a spring effect on the neck and ensure a suction cutting effect.
Tel qu'on le voit illustré sur les dessins, l'opercule a de préférence une surface inférieure pourvue d'une dépression circulaire 19 formant une gorge adjacente à la première lèvre 11. Cette gorge donne en pratique un espace de repli à la première lèvre et assure ainsi un reflux plus facile en cas de ressac et donc une meilleure étanchéité. La position particulière et l'avantage que peut avoir la présence de cette dépression circulaire 19 en usage sont là encore plus clairement illustrés sur la figure 4.As shown in the drawings, the cover preferably has a lower surface provided with a circular depression 19 forming a groove adjacent to the first lip 11. This groove in practice gives a fold space to the first lip and thus ensures easier backflow in case of surf and therefore a better seal. The particular position and the advantage that can have the presence of this circular depression 19 in use are here even more clearly illustrated in FIG. 4.
Selon un mode tout particulièrement préféré de l'invention, la jupe périphérique 5 a une partie supérieure interne pourvue d'une rainure 21 formant, de par sa position, une troisième lèvre 23 externe aux deux autres, qui crée une tension radiale et applique une pression sur le bouchon lorsque celui- ci est fixé au goulot et qui assure donc un meilleur serrage de l'anneau de tension 7 contre le bourrelet 9 du goulot 3, avec en outre une compression maximale des première et seconde lèvres 11 et 13 en position pliée. La troisième lèvre 23 assure également un point de contact supplémentaire avec le goulot.According to a particularly preferred embodiment of the invention, the peripheral skirt 5 has an internal upper portion provided with a groove 21 forming, by its position, a third lip 23 external to the other two, which creates a radial tension and applies a pressure on the cap when it is attached to the neck and which therefore ensures a better tightening of the tension ring 7 against the bead 9 of the neck 3, with further compression of the first and second lips 11 and 13 in position folded. The third lip 23 also provides an additional point of contact with the neck.
Bien entendu, comme il est de pratique habituelle, la jupe peut avantageusement être pourvue d'une patte de traction 25 associée a un mince de déchirement 27 pour faciliter le retrait du bouchon à même le goulot. Le bouchon selon l'invention est de préférence injecté en une seule pièce en matière plastique.Of course, as is common practice, the skirt may advantageously be provided with a pull tab 25 associated with a thin tear 27 to facilitate removal of the plug from the neck. The plug according to the invention is preferably injected in one piece of plastic material.
De par sa structure, il présente plusieurs avantages. Tout d'abord, il assure une imperméabilité parfaite du goulot. Il assure également une bonne étanchéité tout en faisant barrière aux échanges entre le contenu de la bonbonne et l'extérieur. Ceci évidemment est essentiel pour protéger de toute contamination du liquide destiné à la consommation humaine. Le bouchon selon l'invention a donc l'avantage d'être parfaitement hermétique.Because of its structure, it has several advantages. First, it ensures perfect impermeability of the neck. It also ensures a good seal while being a barrier to exchanges between the contents of the bottle and the outside. This obviously is essential to protect from any contamination of the liquid intended for human consumption. The plug according to the invention therefore has the advantage of being perfectly hermetic.
De par sa structure et la position de ses lèvres, le mouvement de l'eau et de tout autre liquide contenu dans la bonbonne aussitôt après que celle-ci est remplie, se trouve bloqué. Lors d'une manutention de stockage et de livraison, il n'y a donc plus de problème potentiel de fuite.Due to its structure and the position of its lips, the movement of water and any other liquid contained in the bottle immediately after it is filled, is blocked. When handling storage and delivery, there is no longer a potential problem of leakage.
À ce sujet, on notera à nouveau que la première lèvre 11 a l'avantage de contenir le ressac au coup de bélier provoqué par le mouvement du liquide dans le goulot. Du fait du profil de la gorge, elle permet ainsi au liquide de refluer. La troisième lèvre 23 a également l'avantage de corriger éventuellement la différence propre à chaque modèle de bonbonne et ainsi assurer une parfaite tension de l'anneau 7. La troisième lèvre 23 en se positionnant force de plus près la tension exercée sur l'opercule et de ce fait, plaque encore mieux les première et seconde lèvres 11 et 13 sur le dessus du goulot.In this regard, it will be noted again that the first lip 11 has the advantage of containing the water hammer surf caused by the movement of the liquid in the neck. Because of the profile of the throat, it allows the liquid to reflux. The third lip 23 also has the advantage of possibly correcting the difference specific to each model of bottle and thus ensure a perfect tension of the ring 7. The third lip 23 by positioning forces more closely the tension exerted on the operculum and therefore, plate even better the first and second lips 11 and 13 on the top of the neck.
II va de soi que diverses modifications pourraient être apportées au mode de réalisation qui vient d'être illustré sans pour autant sortir du cadre de la présente invention telle que revendiquée ci-après. It goes without saying that various modifications could be made to the embodiment which has just been illustrated without departing from the scope of the present invention as claimed hereinafter.
