Description

Bouchon à ouverture sécurisée Domaine technique Secure opening cap Technical area
L’invention concerne un bouchon à ouverture sécurisée pour un récipient. The invention relates to a secure opening cap for a container.
Etat de la technique State of the art
Pour la sécurité des enfants, il est généralement souhaitable qu’ils ne puissent pas accéder au contenu d’un récipient, afin de ne pas risquer d’ingérer un produit potentiellement toxique ou s’étouffer en avalant un ou des objets contenus dans le récipient. For the safety of children, it is generally desirable that they cannot access the contents of a container, so as not to risk ingesting a potentially toxic product or choking on swallowing one or more objects contained in the container. .
A cet effet, il est connu de munir les bouchons des récipients d’un dispositif d’ouverture sécurisée. For this purpose, it is known to provide the caps of the receptacles with a secure opening device.
Le principe général de ces bouchons est de nécessiter une combinaison d’opérations qui n’est en principe pas à la portée d’un jeune enfant. The general principle of these plugs is to require a combination of operations which in principle is not within the reach of a young child.
Par exemple, les documents US 5,316,162 et US 5,520,305 décrivent des bouchons à ouverture sécurisée comprenant une bague adaptée pour être solidarisée au goulot d’un récipient et un capuchon amovible vis-à-vis de la bague. La bague présente une gorge circonférentielle et le capuchon comprend un ergot agencé dans la gorge de la bague. La gorge de la bague débouche dans une rainure s’étendant axialement vers le capuchon, la largeur de la rainure étant supérieure ou égale à celle de l’ergot. Le capuchon est mobile en pivotement autour d’un axe longitudinal du bouchon par coulissement de l’ergot dans la bague. Tant que l’ergot n’est pas entièrement en regard de la rainure, le capuchon est ainsi retenu par la bague en position fermée. Pour ouvrir le bouchon, il convient de faire pivoter le capuchon par rapport à la bague de sorte à amener l’ergot en regard de la rainure, ce qui permet de libérer le capuchon par une simple traction dans la direction axiale. La position adéquate est indiquée un alignement de deux flèches présentes respectivement sur la bague et le capuchon. Inversement, le bouchon peut être refermé en positionnant l’ergot en regard de la rainure, en enfonçant le capuchon puis en le faisant pivoter de sorte à engager l’ergot dans la gorge circonférentielle et ainsi maintenir le capuchon sur la bague. For example, documents US 5,316,162 and US 5,520,305 describe caps with a secure opening comprising a ring adapted to be secured to the neck of a container and a removable cap vis-à-vis the ring. The ring has a circumferential groove and the cap comprises a lug arranged in the groove of the ring. The groove of the ring opens into a groove extending axially towards the cap, the width of the groove being greater than or equal to that of the lug. The cap is movable in pivoting about a longitudinal axis of the cap by sliding the lug in the ring. As long as the lug is not entirely opposite the groove, the cap is thus retained by the ring in the closed position. To open the cap, the cap must be rotated relative to the ring so as to bring the lug opposite the groove, which allows the cap to be released by a simple pull in the axial direction. The correct position is indicated by an alignment of two arrows present respectively on the ring and the cap. Conversely, the cap can be closed by positioning the lug opposite the groove, pushing the cap in and then rotating it so as to engage the lug in the circumferential groove and thus hold the cap on the ring.
Un inconvénient de ces bouchons est qu’en position ouverte le capuchon est dissocié du récipient et est donc susceptible d’être perdu ou de chuter, avec un risque de salissure ou d’endommagement. Pour éviter ce type d’inconvénient, il est connu de relier le capuchon au récipient par une charnière. A drawback of these caps is that in the open position the cap is separated from the container and is therefore liable to be lost or to fall, with a risk of soiling or damage. To avoid this type of inconvenience, it is known practice to connect the cap to the container by a hinge.
Cependant, si l’on équipe le bouchon décrit précédemment avec une telle charnière, il existe un risque important que, lors de la fermeture du bouchon, l’ergot reste en regard de la rainure, l’utilisateur oubliant de faire pivoter le capuchon pour engager l’ergot dans la gorge circonférentielle. Dans ce cas, la fonction de sécurisation n’est plus remplie. However, if the stopper described above is fitted with such a hinge, there is a significant risk that, when closing the stopper, the lug remains opposite the groove, the user forgetting to rotate the cap to engage the lug in the circumferential groove. In this case, the security function is no longer fulfilled.
Brève description de l’invention Brief description of the invention
Un but de l’invention est donc de concevoir un bouchon à ouverture sécurisé qui surmonte les inconvénients précités. En particulier, ce bouchon doit permettre d’éviter de perdre le capuchon après ouverture tout en garantissant que lors de la fermeture le bouchon soit à nouveau dans une configuration sécurisée. An aim of the invention is therefore to design a secure opening stopper which overcomes the aforementioned drawbacks. In particular, this cap must make it possible to avoid losing the cap after opening while ensuring that when closing the cap is again in a secure configuration.

Description détaillée de modes de réalisation Detailed description of embodiments
Le bouchon à ouverture sécurisée comprend un capuchon solidaire d’une bague de fixation par une charnière. L’ensemble formé du capuchon et de la bague de fixation est mobile en pivotement par rapport à une pièce solidaire du récipient (pouvant éventuellement faire partie intégrante dudit récipient) autour d’un axe longitudinal du bouchon. Ladite pièce définit un orifice de sortie du récipient. The secure opening cap includes a cap secured to a fixing ring by a hinge. The assembly formed by the cap and the fixing ring is movable in pivoting relative to a part secured to the container (which may optionally be an integral part of said container) about a longitudinal axis of the stopper. Said part defines an outlet orifice of the container.
Le capuchon est pourvu d’un ergot qui, lorsque le bouchon est en position fermée, est logé dans une gorge circonférentielle de la pièce solidaire du récipient. Les formes et dimensions respectives de l’ergot et de la gorge sont choisies de sorte que l’ergot puisse coulisser dans la gorge lorsqu’un utilisateur fait pivoter l’ensemble formé du capuchon et de la bague par rapport au récipient. L’ouverture du bouchon est rendue possible par la présence d’une rainure qui s’étend à partir de la gorge, en débouchant de celle-ci, vers l’orifice de sortie. De manière avantageuse, ladite rainure est inclinée par rapport à l’axe longitudinal du bouchon. Par « inclinée » on entend que la rainure s’étend dans une direction non parallèle à l’axe longitudinal du bouchon. Par exemple, la rainure s’étend dans une direction inclinée de 30 à 60° par rapport à l’axe longitudinal du bouchon. De préférence, la rainure s’étend dans le sens opposé à celui d’un dévissage. The cap is provided with a lug which, when the cap is in the closed position, is housed in a circumferential groove of the part integral with the container. The respective shapes and dimensions of the lug and of the groove are chosen so that the lug can slide in the groove when a user rotates the assembly formed of the cap and of the ring relative to the container. The opening of the stopper is made possible by the presence of a groove which extends from the groove, emerging from the latter, towards the outlet orifice. Advantageously, said groove is inclined relative to the longitudinal axis of the stopper. By “inclined” is meant that the groove extends in a direction not parallel to the longitudinal axis of the stopper. For example, the groove extends in a direction inclined 30 to 60 ° relative to the longitudinal axis of the stopper. Preferably, the groove extends in the direction opposite to that of unscrewing.
Les dimensions de l’ergot et de ladite rainure sont choisies de sorte que l’ergot puisse coulisser dans ladite rainure lorsqu’un utilisateur exerce un mouvement combiné de rotation et de traction sur le capuchon. The dimensions of the lug and of said groove are chosen so that the lug can slide in said groove when a user exerts a combined movement of rotation and traction on the cap.
Du fait de son inclinaison, la rainure est configurée pour que la position de l’ergot à son entrée dans la rainure, c’est-à-dire à l’intersection entre la gorge circonférentielle et la rainure, qui définit une position de début de déverrouillage du bouchon, soit angulairement décalée par rapport à la position de l’ergot à sa sortie de la rainure, c’est-à-dire à l’extrémité de la rainure opposée à la gorge, qui définit une position de fin de déverrouillage du bouchon. A partir de cette position de fin de déverrouillage, un utilisateur peut libérer l’orifice de sortie du récipient en exerçant un effort de pivotement du capuchon autour de l’axe de la charnière, amenant ainsi le bouchon dans sa position ouverte. Due to its inclination, the groove is configured so that the position of the lug as it enters the groove, i.e. at the intersection between the circumferential groove and the groove, which defines a start position release of the stopper, or angularly offset from the position of the lug at its exit from the groove, that is to say at the end of the groove opposite the groove, which defines an end position of unlocking the cap. From this end-of-unlocking position, a user can release the outlet of the container by exerting a force to pivot the cap around the axis of the hinge, thus bringing the cap into its open position.
La gorge et la rainure sont délimitées, du côté de l’orifice du récipient, par une nervure dont la forme et les dimensions sont choisies en adéquation avec la forme et les dimensions de l’ergot pour assurer un mécanisme particulier d’ouverture et de fermeture du bouchon, tel que décrit ci-après. The groove and the groove are delimited, on the side of the orifice of the container, by a rib, the shape and dimensions of which are chosen in line with the shape and dimensions of the lug to ensure a particular mechanism of opening and closing. closure of the cap, as described below.
D’une part, la nervure et l’ergot sont configurés pour que l’ergot ne puisse être extrait de la gorge par un mouvement de traction exercé sur le capuchon dans une direction parallèle à l’axe longitudinal. Une telle fonction peut être assurée, notamment, par le fait que les faces de l’ergot et de la nervure qui se trouvent en vis-à-vis lorsque le bouchon est dans la position fermée, s’étendent radialement par rapport à l’axe longitudinal du bouchon, ou dans toute direction assurant une retenue de l’ergot dans la gorge. On the one hand, the rib and the lug are configured so that the lug cannot be extracted from the groove by a pulling movement exerted on the cap in a direction parallel to the longitudinal axis. Such a function can be ensured, in particular, by the fact that the faces of the lug and of the rib which are facing each other when the stopper is in the closed position, extend radially with respect to the longitudinal axis of the stopper, or in any direction ensuring retention of the lug in the groove.
Ainsi, le bouchon ne peut être ouvert que par l’introduction de l’ergot dans la rainure et l’application d’un mouvement combiné de rotation et de traction sur le capuchon permettant de faire coulisser l’ergot dans la rainure dans la direction de l’orifice de sortie du récipient. D’autre part, la nervure et l’ergot sont configurés pour que l’ergot puisse être encliqueté dans la gorge lorsque l’utilisateur rabat le capuchon vers la bague de fixation, dans toute position autre que la position de début de déverrouillage. Cette fonction peut être assurée, notamment, par le fait que les faces de l’ergot et de la nervure qui se trouvent en vis-à-vis lorsque le bouchon est dans la position ouverte, présentent des pentes respectives propices au glissement desdites faces l’une sur l’autre, associé à une légère déformation élastique du capuchon, jusqu’à l’insertion de l’ergot dans la gorge. Cependant, cette configuration ne se présente, pour la nervure, que dans les positions distinctes de la position de début de déverrouillage. Au contraire, en regard de la position de déverrouillage (dans une direction parallèle à l’axe longitudinal du bouchon), la face de la nervure est conformée de sorte à empêcher un tel glissement de la face de l’ergot ; par exemple, dans cette zone, la face de la nervure forme une marche suffisamment haute pour empêcher le passage de l’ergot vers la gorge. Thus, the cap can only be opened by the introduction of the lug in the groove and the application of a combined movement of rotation and traction on the cap allowing the lug to slide in the groove in the direction from the outlet of the container. On the other hand, the rib and the lug are configured so that the lug can be snapped into the groove when the user folds the cap towards the fixing ring, in any position other than the unlocking start position. This function can be ensured, in particular, by the fact that the faces of the lug and of the rib which are facing each other when the stopper is in the open position, have respective slopes favorable to the sliding of said faces. 'one on the other, associated with a slight elastic deformation of the cap, until the insertion of the lug in the groove. However, this configuration only occurs, for the rib, in the positions distinct from the starting position of unlocking. On the contrary, facing the unlocking position (in a direction parallel to the longitudinal axis of the stopper), the face of the rib is shaped so as to prevent such sliding of the face of the lug; for example, in this zone, the face of the rib forms a sufficiently high step to prevent the passage of the lug towards the groove.
Ainsi, le bouchon peut être fermé dans toute position autre que celle du début du déverrouillage. Ceci permet d’assurer que, après fermeture, l’ergot se trouve retenu dans la gorge, à distance de l’intersection avec la rainure. Par conséquent, même si l’utilisateur ne fait pas pivoter l’ensemble de la bague de fixation et du capuchon par rapport au récipient après avoir rabattu le capuchon sur le récipient, le bouchon ne se trouve pas dans la position de déverrouillage et la fonction d’ouverture sécurisée reste remplie. Pour ouvrir le bouchon à nouveau, l’utilisateur doit faire pivoter l’ensemble de la bague de fixation et du capuchon jusqu’à la position de début de déverrouillage. Thus, the cap can be closed in any position other than that of the start of unlocking. This ensures that, after closing, the lug is retained in the groove, away from the intersection with the groove. Therefore, even if the user does not rotate the assembly of the retaining ring and cap relative to the container after folding the cap back onto the container, the cap is not in the unlock position and function. safe opening remains fulfilled. To open the cap again, the user must rotate the retaining ring and cap assembly to the unlock start position.
Si l’utilisateur tente de fermer le bouchon alors que l’ergot est en regard de la position de déverrouillage, la nervure forme un obstacle qui s’oppose à la fermeture. Pour fermer le bouchon, l’utilisateur doit alors faire pivoter l’ensemble de la bague de fixation et du capuchon par rapport au récipient pour présenter l’ergot en regard d’une face de la nervure autorisant le franchissement de la nervure par l’ergot jusqu’à la gorge. If the user attempts to close the cap while the lug is facing the unlocked position, the rib forms an obstacle that opposes closing. To close the cap, the user must then rotate the assembly of the fixing ring and the cap relative to the container to present the lug facing a face of the rib allowing the rib to pass through the lug to the throat.
Par conséquent, cette configuration particulière du bouchon permet de conserver la fonction d’ouverture sécurisée sans que l’utilisateur n’ait d’action particulière à accomplir lors de la fermeture. Therefore, this particular configuration of the stopper makes it possible to maintain the secure opening function without the user having to take any particular action when closing.
De manière particulièrement avantageuse, la position de début de déverrouillage est matérialisée, sur la partie solidaire du récipient et sur la bague de fixation ou le capuchon, par des indicateurs respectifs qui sont alignés dans ladite position. Le bouchon étant avantageusement réalisé par moulage en matière(s) plastique(s), lesdits indicateurs peuvent être simplement moulés en creux ou en relief. In a particularly advantageous manner, the starting position of unlocking is materialized, on the part secured to the container and on the fixing ring or the cap, by respective indicators which are aligned in said position. The stopper being advantageously made by molding in plastic material (s), said indicators can simply be hollow or raised molded.
La charnière peut être réalisée par tout moyen approprié. Par exemple, la charnière peut se présenter sous la forme d’un film en matière plastique moulé avec la bague de fixation et le capuchon. La charnière forme alors partie intégrante de la bague de fixation et du capuchon. Dans un autre mode de réalisation, la charnière peut comprendre une partie mâle formant un axe et une partie femelle articulée sur la partie mâle, l’une desdites parties appartenant à la bague de fixation et l’autre au capuchon. De manière alternative, un axe distinct, en métal ou en plastique, peut assurer une liaison pivotante entre la bague de fixation et le capuchon. The hinge can be produced by any suitable means. For example, the hinge may be in the form of a plastic film molded with the retaining ring and the cap. The hinge then forms an integral part of the fixing ring and of the cap. In another embodiment, the hinge may comprise a male part forming an axis and a female part articulated on the male part, one of said parts belonging to the fixing ring and the other to the cap. Alternatively, a separate pin, made of metal or plastic, can provide a pivoting connection between the fixing ring and the cap.
La figure 1 est une vue en perspective du bouchon selon un mode de réalisation dans une position ouverte. Figure 1 is a perspective view of the cap according to one embodiment in an open position.
Le bouchon 1 comprend une première partie 10 qui est solidaire du récipient 2. Ladite partie 10 forme avantageusement au moins une partie du goulot du récipient, et définit un orifice 20 de sortie du récipient. Ladite première partie 10 peut faire partie intégrante du récipient, tel qu’illustré sur la vue éclatée de la figure 7, ou bien être une pièce distincte du récipient 2, telle qu’illustrée sur la vue éclatée de la figure 8 mais fixée à celui-ci de manière indémontable. Dans ce dernier cas, la partie 10 est de préférence rigidement liée au récipient, c’est-à-dire de manière fixe par rapport à celui-ci. La fixation de la première partie sur le récipient peut être réalisée par toute technique appropriée, telle qu’une soudure, un collage, un encliquetage, un vissage, etc. The stopper 1 comprises a first part 10 which is integral with the container 2. Said part 10 advantageously forms at least part of the neck of the container, and defines an outlet opening 20 of the container. Said first part 10 may form an integral part of the container, as illustrated in the exploded view of FIG. 7, or else be a separate part from the container 2, as illustrated in the exploded view of FIG. 8 but attached to that - here in a non-removable way. In the latter case, the part 10 is preferably rigidly linked to the container, that is to say fixedly relative to the latter. The fixing of the first part on the container can be carried out by any suitable technique, such as welding, gluing, snapping, screwing, etc.
Le bouchon comprend par ailleurs une deuxième partie 1 1 , laquelle comprend une bague de fixation 1 10 et un capuchon 1 1 1 solidaire de la bague de fixation par une charnière 1 14. The cap also comprises a second part 1 1, which comprises a fixing ring 1 10 and a cap 1 1 1 integral with the fixing ring by a hinge 1 14.
La deuxième partie 1 1 est montée pivotante sur la première partie 10, autour d’un axe longitudinal X du bouchon. A cet effet, la bague de fixation présente un diamètre intérieur légèrement supérieur au diamètre extérieur de la région de la première partie qu’elle entoure. Comme on le voit mieux sur les figures 7 et 8, la bague de fixation et la première partie comprennent respectivement au moins un ergot et une gorge permettant de maintenir la bague de fixation sur la première partie tout en autorisant son pivotement par rapport à celle-ci. La première partie 10 comprend une nervure 100 s’étendant dans une direction radiale. Ladite nervure délimite une gorge circonférentielle 101 , ainsi qu’une rainure 102 qui communique avec la gorge 101 et s’étend vers l’orifice de sortie. The second part 1 1 is pivotally mounted on the first part 10, about a longitudinal axis X of the cap. For this purpose, the fixing ring has an internal diameter slightly greater than the external diameter of the region of the first part which it surrounds. As can be seen better in FIGS. 7 and 8, the fixing ring and the first part respectively comprise at least one lug and a groove making it possible to hold the fixing ring on the first part while allowing it to pivot relative to the latter. this. The first part 10 includes a rib 100 extending in a radial direction. Said rib defines a circumferential groove 101, as well as a groove 102 which communicates with the groove 101 and extends towards the outlet orifice.
Comme expliqué plus haut, la rainure 102 n’est pas orientée parallèlement à l’axe X, mais est inclinée par rapport audit axe. Ainsi, l’extrémité de la rainure 102 située du côté de l’orifice de sortie est décalée angulairement par rapport à l’extrémité opposée, qui forme la jonction avec la gorge 101. De manière avantageuse, la rainure 102 est orientée à l’inverse d’un pas de vis conventionnel. As explained above, the groove 102 is not oriented parallel to the X axis, but is inclined relative to said axis. Thus, the end of the groove 102 located on the side of the outlet port is angularly offset with respect to the opposite end, which forms the junction with the groove 101. Advantageously, the groove 102 is oriented towards the end. reverse of a conventional screw thread.
Le capuchon 1 11 comprend un fond adapté pour obturer l’orifice de sortie et une paroi latérale, de forme générale cylindrique, s’étendant à partir du fond. The cap 11 comprises a bottom adapted to close the outlet and a side wall, generally cylindrical in shape, extending from the bottom.
Un ergot 112 s’étend radialement vers l’intérieur du capuchon à partir de la paroi latérale. A lug 112 extends radially inwardly of the cap from the side wall.
L’ergot présente des dimensions adaptées pour permettre son coulissement dans la gorge 101 et dans la rainure 102. The lug has dimensions adapted to allow it to slide in the groove 101 and in the groove 102.
En position fermée du bouchon, l’ergot 1 12 est positionné dans la gorge 101 et retenu dans celle-ci dans la direction de l’axe X. In the closed position of the cap, the lug 1 12 is positioned in the groove 101 and retained therein in the direction of the X axis.
Pour ouvrir le bouchon, l’utilisateur doit dégager l’ergot 1 12 de la gorge 101 en le faisant coulisser dans la rainure 102, la rainure 102 remplissant la fonction de moyen de déverrouillage du bouchon. La position adéquate de la deuxième partie par rapport à la première partie pour permettre ce déverrouillage est matérialisée par un alignement de deux indicateurs 1 13, 103 agencés respectivement sur la deuxième partie et sur la première partie. To open the cap, the user must release the lug 1 12 of the groove 101 by sliding it in the groove 102, the groove 102 fulfilling the function of unlocking means of the cap. The adequate position of the second part relative to the first part to allow this unlocking is materialized by an alignment of two indicators 1 13, 103 arranged respectively on the second part and on the first part.
Les figures 2 à 4 sont des vues écorchées à différents stades de l’ouverture du bouchon. Figures 2 to 4 are cut-away views at different stages of opening the cap.
Sur la figure 2, le bouchon est en position fermée. L’ergot 1 12 est agencé dans la gorge 101. Les indicateurs présents respectivement sur la première partie et la seconde partie sont décalés angulairement. In Figure 2, the cap is in the closed position. The lug 1 12 is arranged in the groove 101. The indicators present respectively on the first part and the second part are angularly offset.
Sur la figure 3, le bouchon est en position de début de déverrouillage, dans laquelle l’ergot 1 12 est dans la gorge 101 , en regard de la rainure 102. Pour parvenir à cette position, l’utilisateur a tourné la deuxième partie par rapport à la première partie de sorte à aligner les indicateurs 103, 113. Sur la figure 4, le bouchon est en position de fin de déverrouillage, dans laquelle l’ergot sort de la rainure 102, par l’extrémité opposée à la gorge 101 . Pour parvenir à cette position, l’utilisateur a tourné la deuxième partie dans le sens des aiguilles d’une montre (qui est le sens inverse de celui d’un dévissage) tout en exerçant une légère traction dans la direction X pour engager l’ergot dans la rainure 102 puis le faire coulisser dans ladite rainure. Ceci peut impliquer une légère torsion de la deuxième partie, qui est rendue possible par sa constitution en matière plastique. In Figure 3, the cap is in the starting position of unlocking, in which the lug 1 12 is in the groove 101, opposite the groove 102. To reach this position, the user has turned the second part by compared to the first part so as to align the indicators 103, 113. In FIG. 4, the stopper is in the end of unlocking position, in which the lug comes out of the groove 102, through the end opposite the groove 101. To achieve this position, the user turned the second part clockwise (which is counter-unscrewing) while exerting a slight pull in the X direction to engage the lug in the groove 102 and then slide it in said groove. This may involve a slight twisting of the second part, which is made possible by its plastic constitution.
Pour ouvrir complètement le bouchon et libérer l’orifice de sortie, l’utilisateur fait pivoter le capuchon autour de l’axe de la charnière, parvenant ainsi à la position de la figure 1. To fully open the cap and free the outlet, the user rotates the cap around the axis of the hinge, reaching the position shown in Figure 1.
La figure 5 illustre le bouchon ouvert lors d’une tentative de fermeture à partir de la position de début de déverrouillage (les indicateurs 103, 1 13 étant alignés). La partie 1000 de la nervure agencée en regard de l’ergot 1 12 présente une forme et une épaisseur adaptées pour faire obstacle au passage de l’ergot, et empêche ainsi la fermeture du bouchon dans cette position. Cette position n’est en effet pas souhaitable pour la fermeture car, l’ergot se trouvant en regard de la rainure, le bouchon ne serait plus verrouillé, permettant à un enfant de l’ouvrir aisément. Figure 5 shows the cap open during an attempt to close from the unlocking start position (the indicators 103, 1 13 being aligned). The portion 1000 of the rib arranged opposite the lug 1 12 has a shape and a thickness adapted to obstruct the passage of the lug, and thus prevents the closure of the cap in this position. This position is in fact undesirable for closing because, since the lug is opposite the groove, the stopper would no longer be locked, allowing a child to open it easily.
Ceci oblige l’utilisateur à faire pivoter la deuxième partie par rapport à la première partie pour que l’ergot se trouve en regard d’une zone de la nervure 100 autorisant son passage vers la gorge 101 . En pratique, toute position autre que la position de début de déverrouillage est adaptée pour permettre le passage de l’ergot sur la nervure, ce qui ne nécessite pas de la part de l’utilisateur de manipulation complexe pour fermer le bouchon. La figure 6 illustre le bouchon en position fermée. This forces the user to rotate the second part relative to the first part so that the lug is located opposite an area of the rib 100 allowing its passage towards the groove 101. In practice, any position other than the unlocking start position is suitable to allow passage of the lug on the rib, which does not require the user to perform complex manipulation to close the cap. Figure 6 illustrates the cap in the closed position.
Les figures 7 et 8 illustrent deux modes de réalisation du bouchon et du récipient. Figures 7 and 8 illustrate two embodiments of the cap and the container.
Dans le mode de réalisation de la figure 7, la première partie 10 est formée d’un seul tenant avec le récipient. Par exemple, la première partie, qui fait partie du goulot du récipient, peut être formée par moulage, et le reste du récipient par soufflage. In the embodiment of Figure 7, the first part 10 is formed integrally with the container. For example, the first part, which is part of the neck of the container, can be formed by molding, and the rest of the container by blow molding.
Dans le mode de réalisation de la figure 8, la première partie 10 est distincte du récipient, mais configurée pour être solidarisée à celui-ci de manière irréversible, par exemple par soudure ou tout autre moyen adapté. In the embodiment of FIG. 8, the first part 10 is separate from the container, but configured to be secured thereto irreversibly, for example by welding or any other suitable means.
Les figures 9 et 10 sont des vues en coupe du bouchon des figures 7 et 8, respectivement, en position fermée. L’ergot 1 12 présente une face 1 120 située du côté de l’orifice de sortie, qui s’étend dans une direction radiale, comme la face de la nervure 100 qui lui fait face. Cette face 1 120 forme donc une marche qui empêche le passage de l’ergot au-dessus de la nervure 100 et interdit par conséquent l’ouverture du bouchon. Figures 9 and 10 are sectional views of the cap of Figures 7 and 8, respectively, in the closed position. The lug 1 12 has a face 1120 located on the side of the outlet orifice, which extends in a radial direction, like the face of the rib 100 which faces it. This face 1 120 therefore forms a step which prevents the passage of the lug above the rib 100 and consequently prevents the opening of the stopper.
L’ergot 1 12 présente par ailleurs une face 1 121 située du côté du fond du récipient, qui est inclinée par rapport à la direction radiale. Cette face 1 121 forme donc une pente adaptée pour glisser sur la nervure 100 lors de la fermeture du bouchon. The lug 1 12 also has a face 1 121 located on the side of the bottom of the container, which is inclined relative to the radial direction. This face 1 121 therefore forms a slope suitable for sliding over the rib 100 when closing the stopper.
Outre la fonctionnalité d’ouverture sécurisée qui vient d’être décrite, le bouchon peut inclure d’autres fonctionnalités recherchées fréquemment sur des bouchons. In addition to the secure opening feature just described, the cap may include other features that are frequently sought after on caps.
Ainsi, le bouchon peut comprendre un joint d’étanchéité. Comme illustré sur la figure 1 1 , le joint peut se présenter sous la forme d’un disque 1 15 en élastomère agencé dans le fond du capuchon. Lorsque le bouchon est en position fermée, ledit joint 1 15 est interposé entre l’extrémité de la première partie 10 et le capuchon 1 1 1 , assurant ainsi une fermeture hermétique de l’orifice de sortie 20. Thus, the plug may include a seal. As illustrated in Figure 1 1, the seal may be in the form of an elastomeric disc 1 15 arranged in the bottom of the cap. When the cap is in the closed position, said gasket 1 15 is interposed between the end of the first part 10 and the cap 1 1 1, thus ensuring a hermetic closure of the outlet port 20.
Par ailleurs, le bouchon peut comprendre un opercule, amovible lors de la première ouverture du bouchon. Comme illustré sur la figure 12, l’opercule 104 est scellé sur l’extrémité de la première partie 10, obturant ainsi l’orifice de sortie. L’opercule comprend avantageusement une languette facilitant la préhension par l’utilisateur en vue du retrait de l’opercule. Furthermore, the stopper may include a cover, removable when the stopper is first opened. As illustrated in Figure 12, the seal 104 is sealed to the end of the first part 10, thus sealing the exit port. The cover advantageously comprises a tab making it easier for the user to grip it with a view to removing the cover.
Par ailleurs, le bouchon peut comprendre un réducteur de la section de passage, présentant une section réduite par rapport à celle de la première partie, afin de faciliter le dosage du produit contenu dans le récipient. Comme illustré sur la figure 13, le réducteur 105 peut faire partie intégrante de la première partie 10 ou être solidarisé à celle-ci par tout moyen approprié. Furthermore, the stopper may include a reduction of the passage section, having a section reduced compared to that of the first part, in order to facilitate the metering of the product contained in the container. As illustrated in FIG. 13, the reducer 105 can form an integral part of the first part 10 or be secured to the latter by any suitable means.
Naturellement, les différents modes de réalisation décrits et illustrés ne sont pas limitatifs et peuvent éventuellement être combinés. Of course, the various embodiments described and illustrated are not limiting and can optionally be combined.
