Description

Description Description
Titre : Bouchon à doseur incorporé Domaine technique Title: Cap with built-in dispenser Technical area
[0001] La présente invention concerne un bouchon à doseur incorporé. [0002] Elle concerne encore un récipient équipé d’un tel bouchon à doseur intégré pour obturer son ouverture. The present invention relates to a built-in measuring cap. [0002] It also relates to a container equipped with such an integrated measuring cap to close its opening.
Technique antérieure Prior art
[0003] On connaît des bouchons à doseur intégré assurant un dosage fiable et précis d’un volume de produit liquide soutiré d’un récipient, que ce bouchon permet également d’obturer. [0003] There are known plugs with an integrated measuring device ensuring reliable and precise dosing of a volume of liquid product withdrawn from a container, which this plug also makes it possible to close.
De tels bouchons à doseur intégré limitent ainsi la consommation du produit contenu dans le récipient au seul volume requis pour garantir une efficacité optimale de ses fonctions. Such caps with an integrated metering device thus limit the consumption of the product contained in the container to the single volume required to guarantee optimum efficiency of its functions.
[0004] De tels bouchons comprennent typiquement une tête de bouchon comportant un filetage pour assurer leur assemblage avec le col d’une bouteille ou d’un bidon, et un doseur solidaire de la paroi de fond de cette tête et formant saillie par rapport à cette paroi de fond. [0004] Such caps typically include a cap head comprising a thread to ensure their assembly with the neck of a bottle or a can, and a metering unit integral with the bottom wall of this head and forming a projection with respect to this back wall.
[0005] Un tel doseur est typiquement constitué d’un corps tubulaire creux, ouvert à son extrémité libre, pour délimiter avec la paroi de fond de cette tête, un volume de dosage. [0005] Such a metering device typically consists of a hollow tubular body, open at its free end, to define, with the bottom wall of this head, a metering volume.
[0006] Ce doseur se trouve ainsi intégralement inséré dans le volume intérieur de cette bouteille ou de ce bidon, lorsque le bouchon obture celle-ci ou celui-ci. This metering device is thus fully inserted into the internal volume of this bottle or this container, when the stopper closes it or this one.
[0007] Etant ainsi lié à la bouteille ou au flacon, ce doseur se trouve toujours à portée de main, tout en étant effacé dans le récipient en cas de non utilisation. [0007] Being thus linked to the bottle or to the flask, this dispenser is always within reach, while being erased in the container when not in use.
[0008] Par ailleurs, on connaît des produits sensibles à l’oxydation nécessitant des précautions particulières lors de leur conditionnement afin d’éviter toute altération, voire perte, des fonctions normalement assurées par ces produits, avant leur première utilisation. [0008] Furthermore, products sensitive to oxidation are known which require special precautions during their packaging in order to avoid any alteration, or even loss, of the functions normally performed by these products, before their first use.
[0009] Il est ainsi connu après avoir rempli un récipient avec un tel produit, de compléter le volume intérieur, laissé libre de ce récipient, avec un gaz inerte pour en chasser l’air avant sa fermeture. Ce gaz inerte est, par exemple, de l’azote. [0010] Or, malgré le soin apporté dans le conditionnement d’un tel produit sensible à l’oxydation, on constate néanmoins des pertes d’efficacité du produit suite à son stockage. [0009] It is thus known, after filling a container with such a product, to supplement the internal volume, left free of this container, with an inert gas to expel the air therefrom before it is closed. This inert gas is, for example, nitrogen. [0010] However, despite the care taken in the packaging of such an oxidation-sensitive product, there is nevertheless a loss of effectiveness of the product following storage.
[0011] Ces dégradations sont notamment causées par l’air introduit dans le récipient par le bouchon à doseur intégré, le volume intérieur du doseur constituant en effet un volume de stockage important de l’air, qui se trouve naturellement transporté dans le récipient lors de sa fermeture. [0012] A titre d’exemple, cela est observable avec des compositions qui comprennent au moins un principe actif destiné à un traitement vétérinaire et optionnellement à au moins un excipient. These degradations are in particular caused by the air introduced into the container by the integrated measuring cap, the internal volume of the measuring device in fact constituting a large storage volume of the air, which is naturally transported in the container during of its closure. [0012] By way of example, this can be observed with compositions which comprise at least one active principle intended for veterinary treatment and optionally for at least one excipient.
[0013] Il existe donc un besoin pressant pour un bouchon à doseur intégré, dont la conception originale permette de surmonter les inconvénients de l’art antérieur exposés ci-dessus. [0013] There is therefore a pressing need for an integrated measuring cap, the original design of which overcomes the drawbacks of the prior art described above.
Objet de l’invention Object of the invention
[0014] La présente invention vise à pallier les inconvénients de l’art antérieur en proposant un bouchon de fermeture d’un récipient, simple dans sa conception et dans son mode opératoire, empêchant toute altération ou dégradation possible du contenu de ce récipient lors de son stockage. The present invention aims to overcome the drawbacks of the prior art by providing a closure cap for a container, simple in design and in its operating mode, preventing any possible alteration or degradation of the contents of this container during its storage.
[0015] Un autre objet de la présente invention est un tel bouchon de fermeture d’un récipient, présentant un encombrement réduit, lorsqu’il obture ce récipient. Another object of the present invention is such a closure cap for a container, having a small footprint, when it closes this container.
[0016] Encore un objet de la présente invention est un tel bouchon de fermeture d’un récipient dont la dose maximale de produit susceptible d’être reçu dans son réservoir, est maximisée. [0016] Another object of the present invention is such a closure cap for a container in which the maximum dose of product capable of being received in its reservoir is maximized.
[0017] Encore un objet de la présente invention est un tel bouchon de fermeture d’un récipient, dont l’obturation de son réservoir de dosage est particulièrement simple et efficace. Another object of the present invention is such a closure cap for a container, the sealing of its metering reservoir is particularly simple and effective.
[0018] La présente invention vise également un récipient pour contenir un produit notamment liquide ou pâteux équipé d’un tel bouchon de fermeture. [0018] The present invention also relates to a container for containing a product, in particular liquid or pasty, equipped with such a closure cap.
Exposé de l’invention Disclosure of the invention
[0019] A cet effet, l’invention concerne un bouchon pour la fermeture d’un récipient. [0019] To this end, the invention relates to a stopper for closing a container.
Selon l’invention, ce bouchon comprend : According to the invention, this stopper comprises:
- une coiffe comprenant une partie supérieure et une jupe, dite jupe externe, prolongeant la partie supérieure, cette partie supérieure comportant un trou, - a cover comprising an upper part and a skirt, called an external skirt, extending the upper part, this upper part comprising a hole,
- un réservoir définissant un volume intérieur pour recevoir une dose maximale prédéterminée d’un produit, ce réservoir faisant corps avec la coiffe en étant entouré par la jupe externe de sorte à être au moins partiellement reçu dans le récipient lorsque le bouchon obture ce dernier,- a reservoir defining an internal volume to receive a predetermined maximum dose of a product, this reservoir being integral with the cap while being surrounded by the outer skirt so as to be at least partially received in the container when the cap closes the latter,
- le volume intérieur du réservoir étant en communication uniquement avec le trou de la partie supérieure pour permettre l’introduction du produit à doser, et - the internal volume of the reservoir being in communication only with the hole in the upper part to allow the introduction of the product to be dosed, and
- ce bouchon est configuré pour obturer de manière étanche le récipient lorsqu’il est assemblé avec ce dernier. - this stopper is configured to seal off the container when it is assembled with the latter.
De manière avantageuse, la conception originale de ce bouchon doseur garantit un total isolement du volume intérieur du réservoir, du contenu du récipient lorsque le bouchon obture ce récipient. On s’assure ainsi que le contenu du récipient est capable de fournir, lors sa première utilisation, les fonctions pour lesquelles il est prévu initialement. La durée de stockage du produit peut ainsi être garantie voire allongée. Advantageously, the original design of this measuring cap guarantees total isolation of the interior volume of the tank, from the contents of the container when the stopper closes this container. This ensures that the contents of the container are capable of providing, when it is first used, the functions for which it is initially intended. The shelf life of the product can thus be guaranteed or even extended.
[0020] Le corps de ce réservoir définit ainsi une cavité, ou volume de dosage, pour le dosage du produit liquide ou pâteux soutiré du récipient. Le remplissage de cette cavité du réservoir est réalisé depuis le seul côté extérieur à la partie supérieure de la coiffe. Bien entendu, le corps de ce réservoir est plein, ou encore non ajouré, pour permettre le dosage du produit soutiré du récipient. The body of this reservoir thus defines a cavity, or metering volume, for metering the liquid or pasty product withdrawn from the container. The filling of this cavity of the reservoir is carried out from the only side outside the upper part of the cap. Of course, the body of this reservoir is full, or even not perforated, to allow the metering of the product withdrawn from the container.
A titre purement illustratif, le réservoir peut recevoir une quantité de liquide comprise entre 10 ml et 100 ml. Purely by way of illustration, the reservoir can receive a quantity of liquid of between 10 ml and 100 ml.
[0021] Le réservoir s’étend verticalement, ou sensiblement verticalement de manière à pouvoir être inséré dans le col d’un récipient lorsque ce dernier est par exemple une bouteille ou un flacon. The reservoir extends vertically, or substantially vertically so as to be able to be inserted into the neck of a container when the latter is for example a bottle or a flask.
[0022] Un tel bouchon autorise un positionnement fiable et précis de son réservoir par rapport au corps du récipient lors de la fermeture de ce récipient. L’insertion de ce réservoir dans le corps du récipient est donc facilitée. Such a cap allows reliable and precise positioning of its reservoir relative to the body of the container when closing this container. The insertion of this reservoir into the body of the container is therefore facilitated.
[0023] Ce bouchon est conçu pour s'adapter sur le col d'un récipient associé, de façon à former un ensemble étanche. This stopper is designed to fit on the neck of an associated container, so as to form a sealed assembly.
[0024] Le trou dans la partie supérieure de la coiffe est une ouverture traversant de part en part cette partie supérieure. Le corps de la coiffe peut être cylindrique. The hole in the upper part of the cover is an opening passing right through this upper part. The body of the cap can be cylindrical.
[0025] Selon un mode de réalisation particulier de ce bouchon pour la fermeture d’un récipient, il est configuré pour isoler hermétiquement le contenu du récipient lorsqu’il obture ce dernier. [0025] According to a particular embodiment of this cap for closing a container, it is configured to hermetically isolate the contents of the container when it closes the latter.
En d’autres termes, ce bouchon est un bouchon hermétique. In other words, this stopper is an airtight stopper.
Un tel bouchon permet non seulement d’assurer une étanchéité notamment aux liquides mais également aux gaz pour protéger le produit contenu dans le récipient, notamment lorsque ce dernier est sensible à l’oxydation. Such a stopper not only makes it possible to ensure a seal, in particular against liquids but also against gases, to protect the product contained in the container, in particular when the latter is sensitive to oxidation.
A titre purement illustratif, un tel bouchon peut comporter un élément d’étanchéité assurant au niveau de la base du bouchon l’étanchéité entre le goulot du récipient et ce bouchon. Cet élément d’étanchéité peut être un élément d’étanchéité annulaire tel qu’un joint annulaire ou encore un joint à lèvre. Purely by way of illustration, such a stopper may include a sealing element ensuring at the level of the base of the stopper the sealing between the neck of the container and this stopper. This sealing element can be an annular sealing element such as an annular seal or even a lip seal.
[0026] Selon un autre mode de réalisation de ce bouchon pour la fermeture d’un récipient, le trou est positionné de manière centrale dans la partie supérieure de la coiffe. [0026] According to another embodiment of this cap for closing a container, the hole is positioned centrally in the upper part of the cap.
De manière avantageuse, le réservoir ayant un axe longitudinal, cet axe est confondu avec un axe passant par le centre de ce trou. En d’autres termes, le trou étant circulaire, ce trou et le réservoir sont coaxiaux. Advantageously, the reservoir having a longitudinal axis, this axis is merged with an axis passing through the center of this hole. In other words, the hole being circular, this hole and the reservoir are coaxial.
[0027] Selon encore un autre mode de réalisation de ce bouchon pour la fermeture d’un récipient, le corps du réservoir est cylindrique ou évasée, sa partie la plus large étant alors placée du côté du trou de la partie supérieure de la coiffe. [0027] According to yet another embodiment of this cap for closing a container, the body of the reservoir is cylindrical or flared, its widest part then being placed on the side of the hole in the upper part of the cap.
De préférence, ce réservoir présente une forme tronconique. Preferably, this reservoir has a frustoconical shape.
Un tel mode de réalisation assure une insertion facilitée du réservoir dans le col d’un récipient, ce dernier étant par exemple une bouteille ou un flacon. Such an embodiment ensures easy insertion of the reservoir into the neck of a container, the latter being for example a bottle or a flask.
[0028] Selon encore un autre mode de réalisation de ce bouchon pour la fermeture d’un récipient, le réservoir est gradué en étant réalisé dans une matière transparente ou semi-transparente pour autoriser une lecture aisée des mesures des volumes du contenu du réservoir. [0028] According to yet another embodiment of this cap for closing a container, the reservoir is graduated by being made of a transparent or semi-transparent material to allow easy reading of the measurements of the volumes of the contents of the reservoir.
On s’assure ainsi d’un dosage facilité du produit contenu dans le réservoir en vue de son utilisation. This ensures easy dosing of the product contained in the reservoir for use.
[0029] Selon encore un autre mode de réalisation de ce bouchon pour la fermeture d’un récipient, cette coiffe comporte un élément d’obturation pour obturer le trou de la partie supérieure de la coiffe. [0029] According to yet another embodiment of this cap for closing a container, this cap comprises a closure element for closing the hole in the upper part of the cap.
De manière avantageuse, cet élément d’obturation est un clapet, ou couvercle, relié à la partie supérieure de la coiffe par une ou plusieurs articulations. Advantageously, this closure element is a valve, or cover, connected to the upper part of the cover by one or more joints.
Pour assurer le maintien en position de fermeture du clapet, ce dernier peut, par exemple, être clipsé en position. Le bouchon comporte donc des moyens de blocage/déblocage du clapet en position de fermeture, dans laquelle ce dernier obture le trou de la partie supérieure de la coiffe. Alternativement, ou en supplément, cette partie supérieure comportant un rebord annulaire entourant ce trou, l’élément d’obturation comporte un anneau configuré pour son assemblage avec ce rebord annulaire, ainsi qu’une ou plusieurs liaisons reliant un clapet de fermeture de ce trou à cet anneau. Ce clapet de fermeture est ainsi mobile entre une position de fermeture et une position d’ouverture. To ensure that the valve is held in the closed position, the latter can, for example, be clipped into position. The cap therefore comprises means for locking / unlocking the valve in the closed position, in which the latter closes the hole in the upper part of the cover. Alternatively, or in addition, this upper part comprising an annular rim surrounding this hole, the closure element comprises a ring configured for its assembly with this annular rim, as well as one or more links connecting a valve for closing this hole to this ring. This closing valve is thus movable between a closed position and an open position.
A titre d’exemple, cette ou ces liaisons sont des pontages ou des pattes.For example, this or these links are bridges or legs.
De préférence, dans sa position d’ouverture, cette ou ces liaisons sont dimensionnées de sorte que le trou dans la partie supérieure de la coiffe est entièrement dégagé, ou accessible. Preferably, in its open position, this or these link (s) are dimensioned so that the hole in the upper part of the cover is completely clear, or accessible.
Un tel rebord annulaire est à titre illustratif formé par une collerette placée en saillie et s’étendant vers l’extérieur du bouchon, cette collerette étant d’une seule pièce avec le reste de la coiffe. Such an annular rim is, by way of illustration, formed by a collar placed projecting and extending outwardly from the stopper, this collar being in one piece with the rest of the cap.
De manière très avantageuse, le réservoir fait corps avec ce rebord annulaire de sorte que la cavité de dosage, ou cuve du réservoir s’étend jusqu’à l’extrémité supérieure de ce rebord annulaire. On maxime ainsi le volume intérieur, ou la cavité intérieure, de ce réservoir de sorte que la dose maximale que ce réservoir peut contenir est plus importante. Very advantageously, the reservoir is integral with this annular rim so that the metering cavity, or tank of the reservoir extends to the upper end of this annular rim. This maximizes the interior volume, or the interior cavity, of this reservoir so that the maximum dose that this reservoir can contain is greater.
[0030] Selon encore un autre mode de réalisation de ce bouchon pour la fermeture d’un récipient, cette jupe externe comprenant une paroi intérieure, cette paroi intérieure comporte un filetage de vissage destiné à un assemblage étanche avec un filetage correspondant d’un récipient associé. According to yet another embodiment of this cap for closing a container, this outer skirt comprising an inner wall, this inner wall comprises a screw thread intended for a sealed assembly with a corresponding thread of a container associate.
A titre d’exemple, ce bouchon est destiné à être monté en liaison hélicoïdale avec le goulot du récipient, ce dernier étant une bouteille ou un flacon. By way of example, this stopper is intended to be mounted in a helical connection with the neck of the container, the latter being a bottle or a flask.
[0031] Selon encore un autre mode de réalisation de ce bouchon pour la fermeture d’un récipient, ce réservoir et cette coiffe sont formés d’une seule pièce en matière plastique. [0031] According to yet another embodiment of this cap for closing a container, this reservoir and this cap are formed from a single piece of plastic.
A titre d’exemple, le réservoir et la coiffe sont réalisés dans une matière plastique telle qu’en polypropylène (PP), polyéthylène (PE), polychlorure de vinyle (pvc), polycarbonate (PC), ou toute autre matière plastique adaptée. Il peut encore s’agir de matériaux plastiques recyclés ou biosourcés. For example, the reservoir and the cover are made of a plastic material such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (pvc), polycarbonate (PC), or any other suitable plastic material. It can also be recycled or biobased plastic materials.
Il peut encore s’agir d’un mélange d’une matière plastique et d’au moins un composant tel que des antioxydants. It can also be a mixture of a plastic material and at least one component such as antioxidants.
Cet ensemble comprenant le réservoir et la coiffe, peut être formé par exemple par injection ou encore par impression tridimensionnelle (3D). [0032] La présente invention concerne également un récipient équipé d’un dispositif de fermeture. This assembly comprising the reservoir and the cap, can be formed for example by injection or else by three-dimensional (3D) printing. The present invention also relates to a container equipped with a closure device.
Selon l’invention, ce dispositif de fermeture est un bouchon pour la fermeture d’un récipient tel que décrit précédemment. According to the invention, this closure device is a plug for closing a container as described above.
[0033] Ce récipient peut être réahsé en tout matériau tel qu’en matière plastique, en métal ou en verre. This container can be réahsé in any material such as plastic, metal or glass.
[0034] De préférence, ce récipient présente un volume de stockage autorisant sa préhension et sa manipulation à la main. Il peut alors s’agir d’une bouteille, d’un flacon, d’un bocal, d’un bidon ou encore d’un baril. [0035] Un tel récipient peut présenter une section transversale droite circulaire, ovale ou encore polygonale. Dans ce dernier cas, ce récipient peut présenter sur sa surface externe, une butée d’orientation destinée à coopérer avec une surface d’arrêt du corps du bouchon pour conférer une orientation particulière à ce dernier lorsqu’il obture le récipient. Preferably, this container has a storage volume allowing it to be gripped and handled by hand. It can then be a bottle, a flask, a jar, a can or even a barrel. Such a container may have a circular, oval or even polygonal cross section. In the latter case, this container may have on its outer surface an orientation stop intended to cooperate with a stop surface of the body of the stopper in order to give a particular orientation to the latter when it closes the container.
[0036] Ce récipient peut comporter une ou plusieurs poignées pour assurer sa préhension et son transport. This container may include one or more handles to ensure its gripping and its transport.
[0037] La présente invention concerne encore l’utilisation du récipient tel que décrit précédemment pour le stockage de produit sensible à l’oxydation. [0038] Un tel récipient trouve notamment des applications dans le domaine pharmaceutique, par exemple dans le domaine vétérinaire.

Description d’un mode de réalisation Description of an embodiment
[0042] Les dessins et la description ci-après contiennent, pour l’essentiel, des éléments de caractère certain. Ils pourront donc non seulement servir à mieux faire comprendre la présente invention, mais aussi contribuer à sa définition, le cas échéant. [0042] The drawings and the description below contain, for the most part, elements of a certain nature. They can therefore not only serve to better understand the present invention, but also contribute to its definition, if necessary.
[0043] Tout d’abord, on note que les figures ne sont pas à l’échelle. First, we note that the figures are not to scale.
[0044] Les Figures 1 et 2 illustrent de manière schématique un bouchon à doseur intégré selon un mode de réalisation particulier de la présente invention. Figures 1 and 2 schematically illustrate an integrated measuring cap according to a particular embodiment of the present invention.
[0045] Un tel bouchon doseur est particulièrement destiné à obturer des récipients de stockage de produit liquide sensible à l’oxydation, tels que des flacons ou des bouteilles comprenant un goulot. [0045] Such a measuring cap is particularly intended to seal storage containers for liquid product sensitive to oxidation, such as flasks or bottles comprising a neck.
[0046] Ce bouchon comporte une coiffe, ou capuchon, 10 pour venir recouvrir l’extrémité supérieure du goulot du récipient. This stopper has a cap, or cap, 10 to cover the upper end of the neck of the container.
[0047] Cette coiffe 10 comprend une paroi supérieure 11 et une jupe 12, dite jupe externe, prolongeant cette paroi supérieure 11 en s’étendant vers le bas. Le corps de cette coiffe 10 présente ainsi une forme cylindrique. This cover 10 comprises an upper wall 11 and a skirt 12, called the outer skirt, extending this upper wall 11 by extending downwards. The body of this cap 10 thus has a cylindrical shape.
[0048] Cette paroi supérieure 11 comporte un trou 13 autorisant le passage d’un volume de liquide au travers de cette paroi supérieure 11, et par conséquent de la coiffe 10. This upper wall 11 has a hole 13 allowing the passage of a volume of liquid through this upper wall 11, and therefore of the cover 10.
[0049] Une bague d’inviolabilité 14 arrachable est placée à l’extrémité inférieure de la jupe externe 12 en étant reliée à cette jupe par une ligne de moindre résistance. Cette bague d’inviolabilité 14 a pour but de garantir l’intégrité du contenu du récipient avant sa première utilisation. [0050] La jupe externe 12 comprend une paroi intérieure, laquelle comporte un filetage de vissage pour assurer l’assemblage par vissage de la coiffe 10 sur un filetage complémentaire placé à l’extrémité du goulot du récipient. A tear-off tamper-evident ring 14 is placed at the lower end of the outer skirt 12 by being connected to this skirt by a line of least resistance. The purpose of this tamper-evident ring 14 is to guarantee the integrity of the contents of the container before its first use. The outer skirt 12 comprises an inner wall, which comprises a screw thread to ensure the assembly by screwing of the cap 10 on a complementary thread placed at the end of the neck of the container.
[0051] Ce bouchon comporte également un réservoir 15, encore appelé cuve, définissant un volume intérieur pour recevoir une dose maximale prédéterminée d’un liquide contenu dans le récipient. This stopper also includes a reservoir 15, also called a tank, defining an internal volume to receive a predetermined maximum dose of a liquid contained in the container.
[0052] Ce réservoir 15 fait corps avec la coiffe 10 en étant entouré par la jupe externe 12 de sorte à être reçu dans le goulot du récipient lorsque le bouchon obture ce dernier. On s’assure ainsi de l’effacement de ce réservoir 15 en cas de non utilisation, ce bouchon restant ainsi compact. [0053] Le volume intérieur du réservoir 15 est en communication uniquement avec le trou 13 traversant de la paroi supérieure 11 de la coiffe pour permettre l’introduction du produit à doser dans ce réservoir. [0054] De manière avantageuse, la paroi supérieure 11 de la coiffe 10 comprenant un rebord annulaire 16 entourant ce trou 13. Le réservoir 15 fait avantageusement corps avec ce rebord annulaire 16 de sorte que la cavité de dosage du réservoir, ou cuve, s’étend jusqu’à l’extrémité supérieure de ce rebord annulaire. This reservoir 15 is integral with the cap 10 while being surrounded by the outer skirt 12 so as to be received in the neck of the container when the cap closes the latter. This ensures the erasure of this reservoir 15 when not in use, this cap thus remaining compact. The internal volume of the reservoir 15 is in communication only with the hole 13 passing through the upper wall 11 of the cover to allow the introduction of the product to be dosed into this reservoir. Advantageously, the upper wall 11 of the cover 10 comprising an annular rim 16 surrounding this hole 13. The reservoir 15 is advantageously integral with this annular rim 16 so that the metering cavity of the reservoir, or tank, s 'extends to the upper end of this annular rim.
Le volume intérieur du réservoir 15, et ainsi la dose maximale prédéterminée de volume de produit dosable avec ce bouchon, est ainsi optimisée. The internal volume of the reservoir 15, and thus the predetermined maximum dose of volume of product that can be dosed with this stopper, is thus optimized.
[0055] La coiffe 10, la bague d’inviolabilité 14 et le réservoir 15 sont avantageusement formés d’une seule pièce en matière plastique. The cover 10, the tamper-evident ring 14 and the reservoir 15 are advantageously formed from a single piece of plastic material.
[0056] Ce bouchon comporte également un élément d’obturation du trou 13 de remplissage du réservoir 15. This stopper also includes an element for closing the hole 13 for filling the reservoir 15.
Cet élément d’obturation comprend un anneau 17 venant entourer le rebord annulaire 16 de la coiffe 10 pour son assemblage avec cette coiffe 10. Cet anneau 17 est de préférence inséré en force en jouant sur l’élasticité de sa matière de manière à fixer ce dernier sur le rebord annulaire 16. This closure element comprises a ring 17 which surrounds the annular rim 16 of the cover 10 for its assembly with this cover 10. This ring 17 is preferably inserted by force by playing on the elasticity of its material so as to fix this. last on the annular flange 16.
Cet élément d’obturation comprend également une charnière reliant un clapet de fermeture 18 à cet anneau 17 de sorte que ce clapet 18 est mobile entre une position de fermeture et une position d’ouverture. This closure element also comprises a hinge connecting a closure valve 18 to this ring 17 so that this valve 18 is movable between a closed position and an open position.
[0057] En position de fermeture, ce clapet vient fermer de manière étanche ce trou 13 dormant accès au volume intérieur du réservoir 15. Le bouchon comporte de préférence des moyens de maintien en position de fermeture de ce clapet de fermeture, ou couvercle, 18. De manière avantageuse, ce dernier est clipsé en position. In the closed position, this valve seals this fixed hole 13 for access to the internal volume of the reservoir 15. The stopper preferably comprises means for maintaining this closing valve, or cover, in the closed position. Advantageously, the latter is clipped in position.
[0058] De plus, ce bouchon est configuré pour obturer de manière étanche le récipient 19 lorsqu’il est assemblé avec ce dernier. [0058] In addition, this stopper is configured to seal off the container 19 when it is assembled with the latter.
