Description

BOUCHON MUNI D'UN DISPOSITIF ANTI-ROTATION D'UN ANNEAU DE CAP WITH ANTI-ROTATION DEVICE OF A RING
GARANTIEGUARANTEE
DOMAINE TECHNIQUE DE L'INVENTION [0001] L'invention se rapporte à un bouchon à fixer, par exemple par vissage ou accrochage, sur un col de récipient, notamment sur un col de bouteille contenant un liquide, particulièrement des boissons. Ce type de bouchons permet une obturation et une ouverture aisées de la part de l'utilisateur.TECHNICAL FIELD OF THE INVENTION [0001] The invention relates to a cap to be fixed, for example by screwing or hooking, on a container neck, in particular on a bottle neck containing a liquid, particularly drinks. This type of plug allows easy closure and opening on the part of the user.
ETAT DE LA TECHNIQUE ANTERIEURE [0002] Ce type de bouchons comprend généralement trois éléments principaux à savoir un corps principal qui se visse sur le col de la bouteille, un élément d'obturation et un capot de protection. De façon fonctionnelle, il s'agit pour l'utilisateur de pouvoir passer d'un état (ouvert par exemple) à un autre état (fermé par exemple) de façon simple, par intervention de la bouche ou d'une seule main, avec de plus un débit contrôlé du liquide. Les sportifs en particulier trouvent ici un intérêt dans la mesure où ils peuvent boire tout en continuant leur activité physique. Les jeunes enfants peuvent favorablement utiliser des récipients équipés de tels bouchons car leur manipulation est très facile et le débit de liquide est contrôlé.STATE OF THE PRIOR ART [0002] This type of stopper generally comprises three main elements, namely a main body which is screwed onto the neck of the bottle, a closure element and a protective cover. Functionally, it is for the user to be able to move from a state (open for example) to another state (closed for example) in a simple manner, by intervention of the mouth or one hand, with moreover a controlled flow of the liquid. Athletes in particular find here an interest in that they can drink while continuing their physical activity. Young children can favorably use containers equipped with such caps because their handling is very easy and the flow of liquid is controlled.
[0003] Par ailleurs, de façon connue ce type de bouchon comprend au moins un anneau dit d'inviolabilité destiné à garantir que le bouchon n'a jamais été ouvert avant sa première utilisation.Furthermore, in a known manner this type of cap comprises at least one so-called tamper-evident ring intended to ensure that the cap has never been opened before its first use.
[0004] Un premier anneau d'inviolabilité (ou de sécurité) peut être prévu entre la base du corps principal et le col de la bouteille. Cet anneau empêche l'ouverture de la bouteille par ladite base qui est généralement vissée sur le col, et il est relié à ladite base par des pontets sécables régulièrement espacés et séparés les uns des autres par des incisions.A first tamper (or security) ring may be provided between the base of the main body and the neck of the bottle. This ring prevents the opening of the bottle by said base which is generally screwed on the neck, and is connected to said base by breakable bridges regularly spaced apart and separated from each other by incisions.
[0005] Un second anneau d'inviolabilité est en outre prévu entre le capot et le corps principal, plus précisément entre l'extrémité distale dudit capot et la base de la projection tubulaire par laquelle peut sortir le liquide. Cet anneau est destiné à garantir que le capot n'a jamais été déconnecté du bouchon et donc que la bouteille n'a jamais été ouverte par enlèvement du capot. De façon connue, l'anneau est muni intérieurement de protubérances longitudinales c'est-à-dire orientées parallèlement à l'axe du bouchon, qui coopèrent avec des rainures orientées dans le même sens et qui sont prévues par exemple sur une paroi cylindrique spécifique du corps principal du bouchon.A second tamperproof ring is further provided between the cover and the main body, more precisely between the distal end of said cover and the base. of the tubular projection through which the liquid can escape. This ring is intended to ensure that the cap has never been disconnected from the cap and therefore the bottle has never been opened by removing the cap. In known manner, the ring is internally provided with longitudinal protuberances that is to say oriented parallel to the axis of the plug, which cooperate with grooves oriented in the same direction and which are provided for example on a specific cylindrical wall the main body of the cap.
[0006] Le second anneau généralement prévu sur les bouchons est relié à l'extrémité distale du capot par des pontets sécables régulièrement espacés et séparés les uns des autres par des incisions. Lors de la première utilisation, l'utilisateur fait tourner le capot ; ce mouvement induit normalement la cassure des pontets et donc la désolidarisation du capot vis-à-vis de l'anneau qui reste en prise sur la paroi cylindrique spécifique du corps principal du capot grâce aux protubérances de l'anneau logées dans les rainures.The second ring generally provided on the caps is connected to the distal end of the hood by breakable bridges regularly spaced and separated from each other by incisions. During the first use, the user turns the hood; this movement normally induces the breaking of the bridges and thus the disengagement of the cover vis-à-vis the ring which remains engaged on the specific cylindrical wall of the main body of the hood through the protuberances of the ring housed in the grooves.
[0007] Du fait notamment des tolérances de fabrication ou des variations de comportement de la matière plastique en fonction de la température, il peut arriver que la surface de contact entre rainures et protubérances ne soit pas suffisante pour bloquer toute rotation entre l'anneau et le corps du bouchon. Dans un tel cas, la rotation du capot peut entraîner celle de l'anneau dont les protubérances glissent alors par dessus les rainures ; la rotation simultanée du capot et de l'anneau ne permet pas la rupture des pontets dont l'effet garantit normalement la première utilisation du bouchon. Il y a par ailleurs destruction des protubérances de l'anneau ainsi que des rainures du corps du bouchon. Ces effets qui ne sont bien entendu pas souhaités nuisent à la qualité et à l'image du produit fini.[0007] Due in particular to manufacturing tolerances or variations in the behavior of the plastic material as a function of temperature, it may happen that the contact surface between grooves and protuberances is not sufficient to block any rotation between the ring and the body of the cap. In such a case, the rotation of the cover can cause that of the ring whose protuberances then slide over the grooves; the simultaneous rotation of the cover and the ring does not allow the breaking of the bridges whose effect normally ensures the first use of the plug. There is also destruction of the protuberances of the ring and the grooves of the body of the cap. These effects, which are of course not desired, are detrimental to the quality and image of the finished product.
[0008] Par ailleurs, lors du montage du second anneau, lié au capot, sur le corps principal du bouchon, et du fait de l'absence d'indexation angulaire de l'anneau par rapport au corps dans la phase d'approche, il arrive que les protubérances longitudinales de l'anneau entrent en collision avec les cannelures séparant les rainures du corps du bouchon, ce qui a pour effet une détérioration des protubérances et des cannelures, qui rend le fonctionnement ultérieur aléatoire. Le risque est en effet une nouvelle fois que la surface de contact entre protubérances et rainures ne soit plus suffisante pour assurer un blocage du capot par rapport au corps en rotation. Le couple exercé par le consommateur sur le capot a alors pour effet d'entraîner en rotation à la fois le capot et l'anneau, sans rupture des pontets.Furthermore, when mounting the second ring, linked to the hood, on the main body of the cap, and because of the absence of angular indexing of the ring relative to the body in the approach phase, sometimes the longitudinal protuberances of the ring collide with the grooves separating the grooves of the body of the plug, which has the effect of damaging the protuberances and grooves, which makes the subsequent operation random. The risk is indeed once again that the contact surface between protuberances and grooves is no longer sufficient to ensure a locking of the cover relative to the rotating body. The torque exerted by the consumer on the hood then has the effect of rotating both the bonnet and the ring, without breaking the bridges.
[0009] On trouve dans la demande EP 1 065 150 A1 un bouchon du type mentionné ci avant ; seule la fonctionnalité des anneaux est décrite dans ce document de sorte que l'on peut penser qu'ils se présentent sous la forme indiquée ci dessus ; en tout état de cause le problème énoncé ci dessus n'est ni suggéré ni divulgué dans cet art antérieur.[0009] EP 1 065 150 A1 discloses a plug of the type mentioned above; only the functionality of the rings is described in this document so that one can think that they are in the form indicated above; in any case the problem stated above is neither suggested nor disclosed in this prior art.
[0010] D'autres documents peuvent être cités dans le domaine des bouchons de ce type, couramment appelés bouchons sport, qui sont munis d'au moins un anneau d'inviolabilité mais aucun n'évoque le problème énoncé ci dessus.Other documents can be cited in the field of plugs of this type, commonly known as sport plugs, which are provided with at least one tamper-evident ring but none evokes the problem stated above.
EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION
[0011] L'invention vise à remédier aux inconvénients de l'état de la technique et notamment au problème de la rotation non souhaitée du ou des anneaux de garantie simultanément à l'élément (capot ou corps principal) auxquels ils sont liés à l'origine.The invention aims to overcome the disadvantages of the state of the art and in particular the problem of the unwanted rotation of the warranty ring or rings simultaneously with the element (hood or main body) to which they are related to the 'origin.
[0012] Pour ce faire est proposé selon un premier aspect de l'invention un bouchon à fixer sur un col de récipient de liquides comprenant :To do this is proposed according to a first aspect of the invention a cap to be fixed on a liquid container neck comprising:
- Un corps principal pourvu intérieurement d'un moyen de liaison avec ledit col et surmonté d'une projection tubulaire présentant une paroi extérieure définissant un axe de référence ;- A main body internally provided with a connecting means with said neck and surmounted by a tubular projection having an outer wall defining a reference axis;
- Un capot recouvrant ladite projection tubulaire et pourvu intérieurement de moyens d'accrochage élastiques coopérant avec une collerette de la projection tubulaire ; - Un anneau d'inviolabilité situé dans le prolongement distal dudit capot auquel il est relié par des pontets sécables .- A cover covering said tubular projection and provided internally with elastic hooking means cooperating with a flange of the tubular projection; - A tamper evident ring located in the distal extension of said cover to which it is connected by breakable bridges.
[0013] Conformément à l'invention, ledit anneau est pourvu de dents conformées de manière à coopérer avec des protubérances de profil complémentaire régulièrement espacées, prévues sur une extrémité proximale du corps principal, les dents et/ou les protubérances présentant un profil prismatique chanfreiné.According to the invention, said ring is provided with teeth shaped so as to cooperate with regularly spaced complementary profile protuberances provided on a proximal end of the main body, the teeth and / or the protuberances having a chamfered prismatic profile. .
[0014] Avec ce type de profils conjugués, on augmente les surfaces en contact entre les deux éléments ce qui contribue à augmenter les forces de liaison et donc à empêcher leur rotation relative.With this type of conjugate profiles, it increases the contact surfaces between the two elements which helps to increase the bonding forces and thus prevent their relative rotation.
[0015] Préférentiellement, les dents dudit anneau sont orientées de manière à ce que leur partie chanfreinée soit dirigée vers l'extrémité proximale dudit corps principal.Preferably, the teeth of said ring are oriented so that their chamfered portion is directed towards the proximal end of said main body.
[0016] Une telle orientation de la partie chanfreinée permet avantageusement de guider les dents de l'anneau relativement aux protubérances du corps principal, lors de l'assemblage lorsque le capot est rapproché du corps principal parallèlement à l'axe du bouchon. On facilite ainsi la mise en place du capot sur le corps principal du bouchon lors de l'assemblage de ces pièces, sans risque d'endommagement des éléments en contact.Such an orientation of the chamfered portion advantageously allows to guide the teeth of the ring relative to the protuberances of the main body, during assembly when the cover is close to the main body parallel to the axis of the cap. This facilitates the installation of the cap on the main body of the cap during assembly of these parts, without risk of damage to the elements in contact.
[0017] Préférentiellement, les dents de l'anneau comprennent plusieurs parois chanfreinées situées en partie distale.Preferably, the teeth of the ring comprise a plurality of chamfered walls located in the distal portion.
[0018] En outre, le profil prismatique des dents de l'anneau est tel que les dents présentent deux surfaces parallèles entre elles, faisant chacune partie d'une surface cylindrique ou sensiblement cylindrique.In addition, the prismatic profile of the teeth of the ring is such that the teeth have two mutually parallel surfaces, each forming part of a cylindrical or substantially cylindrical surface.
[0019] Selon une autre caractéristique, l'anneau présente un diamètre extérieur supérieur au diamètre extérieur du capot. [0020] Par ailleurs, ledit capot comprend en outre une paroi extérieure pourvue d'au moins une zone facilitant sa préhension. Il est en effet important que l'utilisateur puisse se saisir du capot de façon aisée et fiable, même avec des mains humides par exemple. Pour les enfants il est également important qu'ils puissent saisir le capot le plus facilement possible.According to another feature, the ring has an outer diameter greater than the outer diameter of the hood. Furthermore, said cap further comprises an outer wall provided with at least one zone facilitating its gripping. It is indeed important that the user can grab the hood easily and reliably, even with wet hands for example. For children it is also important that they can grab the hood as easily as possible.
[0021] Une solution peut consister en ce que la paroi extérieure du capot comprenne plusieurs méplats.One solution may be that the outer wall of the cover comprises several flats.
[0022] II est également envisageable, sans sortir du cadre de l'invention, que certaines zones de la paroi extérieure du capot présentent une rugosité supérieure à la rugosité d'autres zones du capot.It is also conceivable, without departing from the scope of the invention, that certain areas of the outer wall of the cover have roughness greater than the roughness of other areas of the cover.

[0024] Pour plus de clarté, les éléments identiques ou similaires sont repérés par des signes de référence identiques sur l'ensemble des figures.For clarity, identical or similar elements are identified by identical reference signs throughout the figures.
DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT
[0025] Comme visible sur la figure 1 , le bouchon dans son ensemble peut être considéré comme axisymétrique et il comprend un corps principal 1 pourvu intérieurement d'un moyen de liaison (non visible) avec le col du récipient (non représenté) contenant un liquide. Le corps principal du bouchon est surmonté d'une projection tubulaire 2 qui présente une paroi extérieure définissant un axe de référence XX.As shown in Figure 1, the plug as a whole can be considered as axisymmetric and it comprises a main body 1 internally provided with a connecting means (not visible) with the neck of the container (no shown) containing a liquid. The main body of the cap is surmounted by a tubular projection 2 which has an outer wall defining a reference axis XX.
[0026] Un capot 3 recouvre la projection tubulaire 2, de préférence au plus près de la projection tubulaire 2. Le capot 3 est pourvu intérieurement de moyens d'accrochage élastique sur la projection tubulaire 2, préférentiellement sur la base de ladite projection 2. Les moyens d'accrochage (non visibles) peuvent se présenter sous la forme d'une rainure intérieure annulaire qui coopère avec une collerette de retenue disposée sur la base (ou partie proximale) de la projection tubulaire 2. Tout autre moyen d'accrochage élastique peut être retenu sans sortir du cadre de l'invention.A cover 3 covers the tubular projection 2, preferably closer to the tubular projection 2. The cover 3 is internally provided with elastic attachment means on the tubular projection 2, preferably on the basis of said projection 2. The attachment means (not visible) may be in the form of an annular inner groove which cooperates with a retaining flange disposed on the base (or proximal part) of the tubular projection 2. Any other elastic attachment means can be retained without departing from the scope of the invention.
[0027] Un anneau d'inviolabilité 4 est prévu, disposé dans le prolongement distal du capot 3 auquel il est relié de façon connue, par des pontets sécables 5 régulièrement répartis et séparés les uns des autres par des incisions. Les pontets sécables 5 sont ainsi prévus à une extrémité de l'anneau adjacente à l'extrémité distale du capot 3.A tamper evident ring 4 is provided, disposed in the distal extension of the cap 3 to which it is connected in a known manner, by breakable bridges 5 regularly distributed and separated from each other by incisions. The breakable bridges 5 are thus provided at one end of the ring adjacent to the distal end of the hood 3.
[0028] Par ailleurs l'anneau 4 présente des dents 6 qui coopèrent avec des protubérances 7 prévues sur une extrémité proximale du corps principal 1. Les protubérances sont ici disposées selon plusieurs secteurs angulaires en arc de cercle, et leur profil est conformé de manière à coopérer dès l'assemblage du bouchon, avec un profil prismatique chanfreiné des dents 6 de l'anneau 4. Alternativement, les protubérances 7 peuvent être disposées suivant un cercle complet. Le nombre de protubérances est en général assez élevé et de préférence supérieur à 10.Furthermore the ring 4 has teeth 6 which cooperate with protuberances 7 provided on a proximal end of the main body 1. The protuberances are here arranged in a plurality of angular sectors in an arc of a circle, and their profile is shaped so to cooperate as soon as the plug is assembled, with a chamfered prismatic profile of the teeth 6 of the ring 4. Alternatively, the protuberances 7 may be arranged in a complete circle. The number of protuberances is generally quite high and preferably greater than 10.
[0029] Sur la figure 2 on remarque notamment que les protubérances 7 présentent une double pente inclinée 9, 10 qui coopère directement avec des chanfreins 11 ,12 ménagés à l'extrémité distale des dents 6. Cette double pente 9,10 assure le guidage des dents 6 vis-à-vis des protubérances 7 lors de l'assemblage du capot sur le corps principal du bouchon. On évite ainsi d'abîmer ces éléments, nombreux, de petite taille donc relativement fragiles.In Figure 2 we note in particular that the protuberances 7 have a double slope inclined 9, 10 which cooperates directly with chamfers 11, 12 formed at the distal end of the teeth 6. This double slope 9,10 provides guidance 6 teeth vis-à-vis the protuberances 7 during the bonnet assembly on the main body of the cap. This avoids damaging these elements, many small, so relatively fragile.
[0030] Par ailleurs, les dents 6 présentent une « racine » ou ancrage dans l'anneau 4 ayant une section plus grande que celle de leur extrémité distale effilée ; autrement dit les extrémités chanfreinées des dents 6 sont orientées vers l'extrémité proximale du corps principal 1.Moreover, the teeth 6 have a "root" or anchoring in the ring 4 having a larger section than that of their tapered distal end; in other words, the chamfered ends of the teeth 6 are oriented towards the proximal end of the main body 1.
[0031] Comme il apparaît plus clairement sur la figure 3, les dents 6 sont chanfreinées selon plusieurs plans : deux chanfreins 11 ,12 sont réalisés selon deux plans formant un angle aigu, à l'extrémité distale des dents 6. L'ensemble des parois 11 , 12 forme une pointe effilée à l'extrémité distale des dents 6, qui correspond et coopère avec une forme conjuguée des protubérances 7.As it appears more clearly in Figure 3, the teeth 6 are chamfered in several planes: two chamfers 11, 12 are made in two planes forming an acute angle, at the distal end of the teeth 6. The set of 11, 12 forms a tapered tip at the distal end of the teeth 6, which corresponds and cooperates with a conjugate form of the protuberances 7.
[0032] Ces profils prismatiques chanfreinés permettent non seulement lors de l'assemblage de guider les dents 6 de l'anneau 4 contre les protubérances 7 du corps principal ; en outre les parois ainsi formées et en contact les unes avec les autres, représentent des surfaces de contact largement plus importantes que dans l'art antérieur. On évite ainsi le problème de la rotation simultanée de l'anneau d'inviolabilité 4 et du capot 3, lorsque lors de la première utilisation, l'utilisateur cherche à faire tourner le capot pour ouvrir la bouteille.These chamfered prismatic profiles allow not only during assembly to guide the teeth 6 of the ring 4 against the protuberances 7 of the main body; furthermore, the walls thus formed and in contact with each other, represent substantially larger contact areas than in the prior art. This avoids the problem of the simultaneous rotation of the tamper ring 4 and the hood 3, when during the first use, the user tries to rotate the hood to open the bottle.
[0033] Sans sortir du cadre de l'invention, les protubérances 7 peuvent être chanfreinées et les dents 6 présentent alors un profil complémentaire , par exemple biseauté mais non nécessairement chanfreiné.Without departing from the scope of the invention, the protuberances 7 may be chamfered and the teeth 6 then have a complementary profile, for example beveled but not necessarily chamfered.
[0034] Dans tous les cas, la solution selon l'invention est relativement simple et tout à fait efficace.In all cases, the solution according to the invention is relatively simple and quite effective.
[0035] Par ailleurs, afin de renforcer les chances d'anti rotation des bouchons selon l'invention, le capot 3 peut présenter une paroi extérieure spécifique, par exemple pourvue d'au moins une zone 15 destinée à en faciliter la préhension. [0036] Par exemple la paroi extérieure du capot 3 peut présenter plusieurs méplats 15 ; les méplats 15 peuvent présenter une rugosité importante, supérieure à celle du reste de la paroi extérieure du capot 3.Furthermore, to enhance the chances of anti rotation plugs according to the invention, the cover 3 may have a specific outer wall, for example provided with at least one zone 15 to facilitate gripping. For example the outer wall of the cover 3 may have several flats 15; the flats 15 may have a high roughness, greater than that of the rest of the outer wall of the cover 3.
[0037] II est en outre possible de prévoir des zones de rugosité importante sur la paroi extérieure du capot 3 que les méplats 15 existent ou non. It is also possible to provide areas of high roughness on the outer wall of the cover 3 that the flats 15 or not.
