  • a first type among these known plugs has a capsule or tank sealed by a membrane or detachable tongue and fixed on the upper part of said plug fitted to a container.
  • To add the substance contained in the tank to said container it is necessary to unscrew the cap, remove the membrane or tongue closing said tank to create an opening for said substance, to turn the cap to pour said substance into said container and finally , to screw the cap on said container to be able to shake it and thus mix the substance with the contents of the latter.
  • the use of a such type of plug therefore requires many tedious steps, some of which, such as that of turning the cap to release the substance in said container, may require some dexterity to avoid pouring the substance next to the latter.
  • Another type of plug has a capsule or reservoir releasing a solid substance in the form of a tablet via a pressure exerted by a finger of the user on said capsule.
  • this type of plug has sealing problems, being reminded that the contents of the container must not accidentally come into contact with the substance enclosed in the capsule.
  • These problems are solved in this type of plug by the presence of a sealing cap attached to the neck of the container.

  • the user can remove the lid, while the cap is fixed on the container. In both cases, many tedious steps are needed again to release the substance.
  • another disadvantage lies in the fact that the operculum of the capsule to release the substance works well only when the substance is in the form of tablets or pellets.
  • the substance in the form of a tablet or a rigid tablet, is between a deformable upper membrane on which the pressure is exerted for releasing said substance, and a lower seal serving as sealing member.

Indeed, when the rigidity of the lid is too low, it breaks during the handling steps, and the substance accidentally mixes with the contents of the container.
  • the pressure to be exerted by the user or consumer on the lid to release the substance must also be high, which can be disadvantageous for some people.
  • this pressure transmitted to the operculum through the substance should be identical, regardless of the form and constitution of the substance.
  • the force exerted on the elastic membrane is transmitted in a reduced manner to the lid and is not always sufficient to tear the latter in order to release the substance.
  • the present invention aims at overcoming at least some of the disadvantages of known caps and caps is intended to provide a stopper to minimize the risk of accidental rupture of the lid to isolate the substance of the contents of the container to which it must be added and allowing a frank and reproducible facilitated rupture of said seal by the user who is as independent as possible from the state or the physical constitution of said substance.
  • the rupture of the sealed seal should ideally be for any type of substance to be added to the contents of the container, particularly in the case of partially filled capsules containing substances that do not always allow to transmit a part sufficient mechanical force exerted by the user able to break the seal seal.

Abstract

The capsule (1) consists of a deformable membrane (2) with its base closed by a seal (3) to form an enclosed volume (V) for at least one substance (S) that is released when the seal is pierced by an integral rupturing component (4). After the seal has been pierced a mechanical pressure is applied to the membrane to expel the substance(s) from the capsule into a container that is fitted with a cap holding the capsule, enabling the substance(s) to be mixed with the container's contents.

Description

La présente invention concerne un bouchon pour récipient à goulot ou col destiné à la distribution de liquides ou de produits pâteux, en particulier pour bouteille d'eau minérale ainsi que le bouchon et le récipient correspondants, ledit bouchon contenant une capsule montée dans ce dernier.The present invention relates to a cap for a neck or neck container for dispensing liquids or pasty products, in particular for mineral water bottle and the corresponding cap and container, said cap containing a capsule mounted therein.

Plus précisément, le bouchon muni d'une capsule selon la présente invention est prévu pour contenir, dans un compartiment hermétiquement isolé du récipient ainsi bouché, une substance ou composition spécifique destinée à être mélangée au contenu dudit récipient juste avant l'utilisation ou la consommation de ce dernier.More specifically, the stopper provided with a capsule according to the present invention is intended to contain, in a hermetically sealed compartment of the container thus clogged, a substance or specific composition intended to be mixed with the contents of said container just before use or consumption. of the last.

Le bouchon de la présente invention peut notamment être utilisé pour boucher des bouteilles en matières synthétiques communément appelées matières plastiques (par exemple en PET) destinées à contenir toutes sortes de liquides alimentaires ou non, plus ou moins fluides, tels que, par exemple, de l'eau minérale, du jus de fruits, des boissons lactées, etc. mais également des sauces ou condiments (ketchup, moutarde, vinaigrette...) ou des liquides non alimentaires (produits d'entretien, détergents...).The plug of the present invention can in particular be used to plug plastic bottles commonly called plastics (for example PET) intended to contain all kinds of liquid food or not, more or less fluid, such as, for example, mineral water, fruit juice, milk drinks, etc. but also sauces or condiments (ketchup, mustard, vinaigrette ...) or non-food liquids (cleaning products, detergents ...).

On connaît déjà, dans ce domaine particulier, bon nombre de bouchons présentant des compartiments renfermant une substance, notamment alimentaire, destinée à être additionnée au contenu du récipient qui contient en général une boisson telle que de l'eau ou du lait, par exemple pour la préparation de boissons énergétiques ou de biberons.In this particular field, a number of corks having compartments containing a substance, especially a food substance, intended to be added to the contents of the receptacle which generally contains a beverage such as water or milk, for example the preparation of energy drinks or baby bottles.

Toutefois, tous les bouchons actuels présentent un certain nombre d'inconvénients plus ou moins gênants.However, all current plugs have a number of disadvantages more or less troublesome.

Un premier type parmi ces bouchons connus présente une capsule ou un réservoir scellé par une membrane ou languette détachable et fixé sur la partie supérieure dudit bouchon équipant un récipient. Pour additionner la substance contenue dans le réservoir audit récipient, il est nécessaire de dévisser le bouchon, de retirer la membrane ou languette fermant ledit réservoir afin de créer une ouverture pour ladite substance, de retourner le bouchon pour verser ladite substance dans ledit récipient et enfin, de revisser le bouchon sur ledit récipient pour pouvoir le secouer et ainsi mélanger la substance avec le contenu de ce dernier. L'utilisation d'un tel type de bouchon nécessite donc de nombreuses étapes fastidieuses, dont certaines, telle que celle consistant à renverser le bouchon pour libérer la substance dans ledit récipient, peuvent demander une certaine dextérité pour éviter de verser la substance à côté de ce dernier.A first type among these known plugs has a capsule or tank sealed by a membrane or detachable tongue and fixed on the upper part of said plug fitted to a container. To add the substance contained in the tank to said container, it is necessary to unscrew the cap, remove the membrane or tongue closing said tank to create an opening for said substance, to turn the cap to pour said substance into said container and finally , to screw the cap on said container to be able to shake it and thus mix the substance with the contents of the latter. The use of a such type of plug therefore requires many tedious steps, some of which, such as that of turning the cap to release the substance in said container, may require some dexterity to avoid pouring the substance next to the latter.

Un autre type de bouchon présente une capsule ou réservoir libérant une substance solide sous forme de comprimé par l'intermédiaire d'une pression exercée par un doigt de l'utilisateur sur ladite capsule. Or, ce type de bouchon présente des problèmes d'étanchéité, étant rappelé que le contenu du récipient ne doit pas venir accidentellement en contact avec la substance renfermée dans la capsule. Ces problèmes sont résolus dans ce type de bouchon par la présence d'un opercule d'étanchéité fixé sur le goulot du récipient. Dans une première variante de réalisation de ce bouchon, l'utilisateur, pour libérer la substance, dévisse d'abord le bouchon pour retirer l'opercule, puis replace le bouchon sur le récipient et libère le comprimé de la capsule par pression sur cette dernière. Dans une deuxième variante, l'utilisateur peut retirer l'opercule, tandis que le bouchon est fixé sur le récipient. Dans les deux cas, de nombreuses et fastidieuses étapes sont à nouveau nécessaires pour libérer la substance. De plus, un autre inconvénient réside dans le fait que l'opercule de la capsule permettant de libérer la substance ne fonctionne bien que lorsque cette substance se présente sous la forme de comprimés ou de pastilles rigides.Another type of plug has a capsule or reservoir releasing a solid substance in the form of a tablet via a pressure exerted by a finger of the user on said capsule. However, this type of plug has sealing problems, being reminded that the contents of the container must not accidentally come into contact with the substance enclosed in the capsule. These problems are solved in this type of plug by the presence of a sealing cap attached to the neck of the container. In a first embodiment of this cap, the user, to release the substance, first unscrews the cap to remove the cap, then puts the cap on the container and releases the tablet from the capsule by pressing on the latter . In a second variant, the user can remove the lid, while the cap is fixed on the container. In both cases, many tedious steps are needed again to release the substance. In addition, another disadvantage lies in the fact that the operculum of the capsule to release the substance works well only when the substance is in the form of tablets or pellets.

Pour limiter le nombre d'étapes nécessaires à la libération de la substance, il a été conçu un type de bouchon dans lequel la substance, sous forme de comprimé ou pastille rigide, est comprise entre une membrane supérieure déformable sur laquelle on exerce la pression pour libérer ladite substance, et un opercule inférieur servant d'élément d'étanchéité. L'opercule inférieur est déchiré par le comprimé lorsque l'utilisateur exerce une pression sur la membrane supérieure.To limit the number of steps necessary for the release of the substance, it has been designed a type of plug in which the substance, in the form of a tablet or a rigid tablet, is between a deformable upper membrane on which the pressure is exerted for releasing said substance, and a lower seal serving as sealing member. The lower lid is torn by the tablet when the user exerts pressure on the upper membrane.

Or la rigidité de l'opercule est un paramètre critique dans la mesure où cette dernière doit être à la fois suffisamment faible pour permettre une libération aisée de la substance (de préférence quel que soit son état) et suffisamment élevée pour permettre audit opercule de résister à la pression qui peut être exercée sur ce dernier par le contenu du récipient lorsqu'il est comprimé pendant les étapes de manutention du récipient. En effet, lorsque la rigidité de l'opercule est trop faible, il survient des ruptures de celui-ci lors des étapes de manutention, et la substance se mélange accidentellement avec le contenu du récipient.However, the rigidity of the cap is a critical parameter insofar as the latter must be both low enough to allow easy release of the substance (preferably whatever its state) and high enough to allow said operculum to resist. the pressure that can be exerted on the latter by the contents of the container when it is compressed during the handling steps of the container. Indeed, when the rigidity of the lid is too low, it breaks during the handling steps, and the substance accidentally mixes with the contents of the container.

Lorsque l'opercule est assez rigide, la pression devant être exercée par l'utilisateur ou le consommateur sur l'opercule pour libérer la substance doit également être élevée, ce qui peut être désavantageux pour certaines personnes. Dans l'idéal, cette pression transmise à l'opercule par l'intermédiaire de la substance, devrait être identique, quelle que soit la forme et la constitution de la substance. Or, dans l'utilisation d'une substance sous forme de poudre, par exemple, l'effort exercé sur la membrane élastique est transmis de manière réduite à l'opercule et ne suffit pas toujours à déchirer ce dernier afin de libérer la substance.When the lid is rigid enough, the pressure to be exerted by the user or consumer on the lid to release the substance must also be high, which can be disadvantageous for some people. Ideally, this pressure transmitted to the operculum through the substance, should be identical, regardless of the form and constitution of the substance. However, in the use of a substance in powder form, for example, the force exerted on the elastic membrane is transmitted in a reduced manner to the lid and is not always sufficient to tear the latter in order to release the substance.

Le désavantage principal de ce type de bouchon est donc qu'il est limité à l'utilisation de substances sous forme de comprimés ou de pastilles rigides qui sont seuls capables de transmettre sensiblement intégralement l'effort exercé par le doigt à l'opercule. Ce type de bouchon ne peut donc pas être appliqué dans le cas de substances liquides ou sous forme de poudre. De plus, la rupture de l'opercule est une fonction de la forme de la substance, ce qui exclut toute reproductibilité de ladite rupture.The main disadvantage of this type of plug is that it is limited to the use of substances in the form of tablets or rigid pellets which alone are capable of transmitting substantially completely the force exerted by the finger to the cap. This type of cap can not therefore be applied in the case of liquid substances or in the form of powder. In addition, the rupture of the lid is a function of the shape of the substance, which excludes any reproducibility of said rupture.

La présente invention vise à pallier au moins certains des inconvénients des bouchons à capsules connus et a pour but de fournir un bouchon permettant de minimiser les risques d'une rupture accidentelle de l'opercule permettant d'isoler la substance du contenu du récipient auquel elle doit être ajoutée et permettant une rupture facilitée franche et reproductible dudit opercule par l'utilisateur qui soit la plus indépendante possible de l'état ou de la constitution physique de ladite substance.The present invention aims at overcoming at least some of the disadvantages of known caps and caps is intended to provide a stopper to minimize the risk of accidental rupture of the lid to isolate the substance of the contents of the container to which it must be added and allowing a frank and reproducible facilitated rupture of said seal by the user who is as independent as possible from the state or the physical constitution of said substance.

En effet, la rupture de l'opercule étanche doit idéalement pouvoir se faire pour n'importe quel type de substance à ajouter au contenu du récipient, en particulier dans le cas de capsules partiellement remplies contenant des substances ne permettant pas toujours de transmettre une partie suffisante de l'effort mécanique exercé par l'utilisateur apte à briser l'opercule d'étanchéité.Indeed, the rupture of the sealed seal should ideally be for any type of substance to be added to the contents of the container, particularly in the case of partially filled capsules containing substances that do not always allow to transmit a part sufficient mechanical force exerted by the user able to break the seal seal.

Ceci peut notamment être le cas pour des liquides très fluides, des solides très déformables ou compressibles tels que des poudres fines, des granulés très friables, etc.This can especially be the case for very fluid liquids, highly deformable or compressible solids such as fine powders, highly friable granules, etc.

Par ailleurs, le bouchon selon l'invention doit pouvoir être utilisé avec peu d'effort et peu de manipulations par une seule main du consommateur, l'ouverture ne devant, de préférence, pas entraîner la formation de pièces détachées.Furthermore, the plug according to the invention must be used with little effort and little manipulation by one hand of the consumer, the opening should preferably not lead to the formation of spare parts.

La présente invention a donc pour objet un bouchon selon la revendication 1.The present invention therefore relates to a stopper according to claim 1.

D'autres caractéristiques avantageuses ressortent des revendications dépendantes.Other advantageous features are apparent from the dependent claims.

Elle a également pour objet un récipient à goulot ou col destiné à la distribution de liquides ou de produits pâteux, en particulier d'eau minérale, caractérisé en ce qu'il comporte un bouchon selon la présente invention.It also relates to a neck or neck container for dispensing liquids or pasty products, in particular mineral water, characterized in that it comprises a plug according to the present invention.

Other features and advantages of the invention will emerge from the description which follows, given by way of example and with reference to the appended drawings in which:

  • the Fig. 8 is an enlarged partial view in perspective of the central part of the figure 5 .

On se réfère d'abord à la figure 1 qui montre une vue schématique en élévation latérale et en coupe d'un premier mode de réalisation de bouchon selon l'invention.We first refer to the figure 1 which shows a schematic view in side elevation and in section of a first embodiment of plug according to the invention.

Dans la réalisation représentée, ledit bouchon comprend une capsule 1 étanche essentiellement constituée par une membrane déformable 2 scellée à sa base par un opercule 3 perçable de sorte à définir un volume étanche V destiné à contenir au moins une substance S entre ladite membrane déformable 2 et ledit opercule 3 présentant au moins un moyen de rupture 4 intégré dudit opercule 3 perçable apte à le déchirer pour une libération d'une quantité efficace de substance(s) S suite à une déformation suffisante de ladite membrane déformable 2 due à un effort mécanique extérieur exercé sur cette dernière.In the embodiment shown, said plug comprises a sealed capsule 1 consisting essentially of a deformable membrane 2 sealed at its base by a pierceable lid 3 so as to define a sealed volume V intended to contain at least one substance S between said deformable membrane 2 and said lid 3 having at least one integral breaking means 4 of said pierceable lid 3 capable of tearing it for release of an effective amount of substance (s) S following a sufficient deformation of said deformable membrane 2 due to an external mechanical force exerted on the latter.

L'incorporation dans le sein même de ladite capsule 1 du moyen de rupture 4 permet de fabriquer une capsule 1 monopièce prête à être montée dans le bouchon choisi pour boucher le récipient souhaité qui ne nécessite pas de prévoir un élément extérieur additionnel pour la rupture de l'opercule 3.The incorporation into the very bosom of said capsule 1 of the breaking means 4 makes it possible to manufacture a one-piece capsule 1 ready to be mounted in the stopper chosen to seal the desired container which does not require an additional external element for the rupture of the the operculum 3.

De préférence, la membrane déformable 2 est réalisée en PVC, un matériau résilient, permettant à l'utilisateur de la déformer suffisamment, par exemple avec un doigt, pour réussir à rompre l'opercule 3 et ainsi libérer la ou les substances S dans le contenu du récipient. La forme de la membrane déformable 2 proprement dite peut être quelconque même si une forme globale du type de celle d'une cloche, de préférence une cloche dont le sommet est plat, par exemple en forme de disque, d'ovale, etc, peut être préférée.Preferably, the deformable membrane 2 is made of PVC, a resilient material, allowing the user to deform sufficiently, for example with a finger, to succeed in breaking the lid 3 and thus release the substance or substances S in the container contents. The shape of the deformable membrane 2 itself may be unspecified even if a global shape of the type of that of a bell, preferably a bell whose apex is flat, for example disk-shaped, oval, etc., may to be preferred.

Selon une autre caractéristique non représentée, la membrane déformable 2 peut comporter au moins un moyen de déformation préférentielle de cette dernière réalisé sous la forme d'un point, d'une ligne ou d'une surface de déformation préférentielle, par exemple, sous la forme d'un renfoncement en forme d'une portion de rainure de section sensiblement semi-cylindrique située sur le flanc de ladite membrane déformable 2. Ce moyen permet de créer un point, une ligne ou une surface amorçant et facilitant la déformation du restant de la membrane déformable 2 pour atteindre l'objectif souhaité, à savoir une concentration des efforts conduisant à une déformation suffisamment marquée de ladite membrane déformable 2 qui permette d'assurer un déchirement ou une rupture suffisante de l'opercule 3 en vue de permettre le passage de la ou des substances S contenues dans le volume étanche V et destinées à être additionnées au contenu du récipient muni de la capsule 1 selon l'invention.According to another feature not shown, the deformable membrane 2 may comprise at least one means of preferential deformation of the latter made in the form of a point, a line or a preferred deformation surface, for example, under the shape of a recess in the form of a groove portion of substantially semi-cylindrical section located on the side of said deformable membrane 2. This means allows to create a point, a line or a priming surface and facilitating the deformation of the remainder of the deformable membrane 2 to achieve the desired objective, namely a concentration of forces leading to a sufficiently marked deformation of said deformable membrane 2 which allows to provide a tear or sufficient rupture of the lid 3 to allow the passage of the substance or substances S contained in the sealed volume V and intended to be added to the contents of the container provided with the capsule 1 is the invention.

Dans l'exemple préféré susvisé, le pouce ou le doigt de l'utilisateur appuyant d'abord sur la membrane déformable 2 à l'endroit où se situe le ou les moyens de déformation préférentielle (qui sont situés à un endroit commode d'accès pour le consommateur, par exemple à un niveau proche du sommet), amorce une déformation relativement plus aisée de la membrane déformable 2 qui se propage aux surfaces restantes, plus rigides, en les entraînant dans le mouvement de déformation dont l'ampleur devient rapidement suffisante pour entraîner une ouverture de passage significative pour la ou les substances S dans l'opercule 3 perçable.In the preferred example referred to above, the user's thumb or finger first pressing the deformable membrane 2 at the location where the preferential deformation means (s) (which are located at a convenient location of access for the consumer, for example at a level close to the vertex), initiates a relatively easier deformation of the deformable membrane 2 which propagates to the remaining surfaces, more rigid, by driving them into the deformation movement whose magnitude quickly becomes sufficient to cause a significant opening opening for the substance or substances S in the pierceable lid 3.

Dans le cas où la membrane déformable 2 est réalisée en un matériau souple ou élastique, tel qu'un caoutchouc naturel, il n'est pas exclu que ladite membrane reprenne sa forme initiale lorsque la pression exercée par le doigt de l'utilisateur cesse, préservant ainsi l'aspect esthétique originel du bouchon.In the case where the deformable membrane 2 is made of a flexible or elastic material, such as a natural rubber, it is not excluded that said membrane returns to its original shape when the pressure exerted by the finger of the user ceases, thus preserving the original aesthetic appearance of the stopper.

Bien entendu, d'autres matériaux déformables remplissant la même fonction peuvent également convenir, même si le PVC est préféré, notamment en raison de ses propriétés physico-chimiques particulièrement adaptées à l'emploi décrit.Of course, other deformable materials fulfilling the same function may also be suitable, even if PVC is preferred, in particular because of its physicochemical properties particularly suitable for the use described.

Il va de soi que la ou les matières utilisées pour la réalisation de la capsule 1, du bouchon et plus particulièrement celle ou celles utilisées pour la réalisation de la membrane déformable 2 et de l'opercule 3 devront être chimiquement et physiquement compatibles avec la nature du contenu liquide ou pâteux du récipient ainsi bouché, respectivement avec la ou les substances S contenues dans le volume étanche V délimité par ladite membrane déformable 2 et ledit opercule 3. De plus, si le récipient bouché par le bouchon selon l'invention est destiné à contenir un produit alimentaire liquide ou pâteux, il conviendra également de s'assurer que les matériaux précités sont bien de qualité alimentaire et que le produit bouché commercialisé réponde bien aux normes d'hygiène applicables.It goes without saying that the material or materials used for the realization of the capsule 1, the plug and more particularly that or those used for the production of the deformable membrane 2 and the lid 3 will have to be chemically and physically compatible with the nature. liquid or pasty content of the container thus clogged, respectively with the substance or substances S contained in the sealed volume V delimited by said deformable membrane 2 and said lid 3. In addition, if the container plugged by the cap according to the invention is intended to contain a liquid or pasty food product, it will also be necessary to ensure that the aforementioned materials are of food quality and that the clogged product marketed meets the applicable hygiene standards.

Ainsi, une seule opération suffit, après l'ouverture du capot de protection 19 (cf. par ex. les figures 1 ou 4), pour transférer la ou les substances S dans le récipient.Thus, a single operation is sufficient after the opening of the protective cover 19 (see, for example, figures 1 or 4 ), to transfer the substance or substances S into the container.

L'opération d'ouverture dudit capot de protection 19 peut également être réalisée par une seule main, par exemple, en saisissant le récipient dans la paume et en dégageant ledit capot de protection 19 par l'action du pouce de la même main. La figure 19 illustre un bouchon muni d'une capsule du type de celle de la figure 1 lorsque le capot de protection 19 a été ouvert, la membrane déformable 2 enfoncée suffisamment pour que l'opercule 3 soit déchiré, la ou les substances S tombant alors dans ledit récipient.The opening operation of said protective cover 19 can also be performed by one hand, for example, by grasping the container in the palm and disengaging said protective cover 19 by the action of the thumb of the same hand. FIG. 19 illustrates a cap provided with a capsule of the type of that of figure 1 when the protective cover 19 has been opened, the deformable membrane 2 is depressed sufficiently so that the lid 3 is torn, the substance or substances S then falling into said container.

Pour la fermeture, l'index ramène le capot de protection 19 sur la pièce de base 20 jusqu'au « clic » de fermeture.For closure, the index returns the protective cover 19 on the base part 20 until the "click" closing.

La constitution de la pièce de base 20 et des moyens d'ouverture et de fermeture 33, 34 sera détaillée ultérieurement.The constitution of the base part 20 and the opening and closing means 33, 34 will be detailed later.

La capsule 1 comprend au moins une pièce intermédiaire 6 prévue entre ladite membrane déformable 2 et ledit opercule 3, ladite pièce intermédiaire 6 présentant au moins un moyen de rupture 4 de ladite membrane déformable 2 qui peut être activé lors d'une déformation suffisante de cette dernière.The capsule 1 comprises at least one intermediate piece 6 provided between said deformable membrane 2 and said lid 3, said intermediate piece 6 having at least one breaking means 4 of said deformable membrane 2 which can be activated during a sufficient deformation of this last.

Comme on peut le voir sur les figures 1 à 3, l'extrémité du moyen de rupture 4 opposée à la charnière 9 du clapet pivotant formé ou à l'attache dudit moyen de rupture 4 sur la pièce intermédiaire 6 peut être munie d'une attache mince ou pont 10' faisant office de pont de rupture qui sécurise ledit moyen 4 tant que le bouchon n'est pas effectivement utilisé. Ce pont 10' impose également à l'utilisateur, lorsqu'il souhaite déchirer l'opercule 3, d'appliquer une pression ou force sur l'élément arqué 15 assez élevée qui suffit à la rupture dudit pont 10' et qui, en même temps et du fait de sa forte intensité et de son application brusque, permet de réaliser une cassure ou coupure plus nette ou plus franche de l'opercule 3, par rapport à une rupture progressive par application d'une force qui croît au fur et à mesure, libérant ainsi toute la substance S contenue dans la capsule 1.As can be seen on the Figures 1 to 3 , the end of the breaking means 4 opposite the hinge 9 of the pivoting valve formed or the attachment of the said breaking means 4 to the intermediate piece 6 may be provided with a thin clip or bridge 10 'serving as a bridge of rupture which secures said means 4 as the plug is not actually used. This bridge 10 'also imposes on the user, when he wishes to tear the lid 3, to apply a pressure or force on the arched element 15 which is sufficient to break said bridge 10' and which, at the same time time and because of its high intensity and its abrupt application, makes it possible to break or cut more clearly or more frankly of the operculum 3, with respect to a progressive rupture by application of a force that grows as and when measuring, thus releasing all the substance S contained in the capsule 1.

Ceci est le cas tant que la membrane déformable 2 n'a pas été assez déformée (enfoncée) pour transmettre l'effort mécanique soit en venant en contact elle-même ou pour transmettre la pression via la substance S à l'opercule 3 ou à la surface d'un appui 14 tel que représenté à la figure 2 et décrit plus en détail ci-après, et que l'effort ainsi transmis n'est pas suffisant pour rompre ce pont 10 qui relie deux portions de surfaces entre elles, effort comparativement plus faible que celui nécessaire pour percer l'opercule 3.This is the case as long as the deformable membrane 2 has not been sufficiently deformed (depressed) to transmit the mechanical force either by coming into contact itself or to transmit the pressure via the substance S to the lid 3 or the surface of a support 14 as shown in FIG. figure 2 and described in more detail below, and that the force thus transmitted is not sufficient to break the bridge 10 which connects two portions of surfaces between them, a comparatively lower force than that required to pierce the lid 3.

De manière avantageuse, l'anneau 7 est réalisé par injection d'une matière synthétique, de préférence de polyéthylène, au niveau ou à proximité immédiate du ou des ponts 10 de rupture.Advantageously, the ring 7 is made by injection of a synthetic material, preferably polyethylene, at or in the immediate vicinity of the rupture bridge (s).

La forme des moyens de rupture 4 ainsi que le nombre de ces derniers est déterminé en fonction de la résistance au déchirement procuré par l'opercule 3 qui est habituellement réalisé sous la forme d'une pellicule d'aluminium éventuellement plastifiée ou analogue.The shape of the breaking means 4 as well as the number of these is determined according to the tear resistance provided by the lid 3 which is usually made in the form of an optionally plasticized aluminum film or the like.

On a représenté à titre d'exemple non limitatif des dents saillantes pour les moyens de rupture 4 mais d'autres géométries saillantes et tranchantes sont également possibles, par exemple sous la forme de pointes verticales protubérantes en saillie dirigées vers l'opercule 3.By way of nonlimiting example, protruding teeth are shown for the breaking means 4 but other salient geometries and cutting edges are also possible, for example in the form of protruding projecting vertical points directed towards the cover 3.

Conformément à la variante de réalisation illustrée aux figures 2 et 3, le moyen de rupture 4 présente au moins un élément saillant 12 sensiblement vertical dirigé vers l'opercule 3 et facilitant le perçage de ce dernier. Cette variante sera décrite plus en détail plus loin.According to the embodiment variant illustrated in figures 2 and 3 , the breaking means 4 has at least one substantially vertical salient element 12 directed towards the cap 3 and facilitating the drilling of the latter. This variant will be described in more detail below.

Avantageusement, la pièce intermédiaire 6, prévue entre ladite membrane déformable 2 et ledit opercule 3, est réalisée sous la forme d'un anneau 7 périphérique sur lequel s'appuie localement, par l'intermédiaire d'une portion de charnière 9, un élément arqué 15 épousant sensiblement et au moins localement la forme de la membrane déformable 2 dans son état initial et dont l'extrémité libre 16 est réalisée sous la forme d'au moins un élément saillant 12 ou pointu dirigé vers l'opercule 3, une surface d'appui 14 utile étant prévue sur ledit élément arqué 15 qui est capable de transmettre un effort mécanique extérieur exercé sur ladite membrane déformable 2 par l'utilisateur qui est suffisant pour provoquer le basculement du ou des éléments saillants 12 d'extrémité afin d'obtenir une rupture de l'opercule 3 libérant une quantité efficace de substance(s) S dans le contenu du récipient.Advantageously, the intermediate piece 6, provided between said deformable membrane 2 and said lid 3, is made in the form of a peripheral ring 7 on which a hinge portion 9 locally bears an element arched substantially conforming and at least locally the shape of the deformable membrane 2 in its initial state and whose free end 16 is formed in the form of at least one projecting element 12 or pointed towards the operculum 3, a surface bearing support 14 being provided on said arcuate element 15 which is capable of transmitting an external mechanical force exerted on said deformable membrane 2 by the user which is sufficient to cause the tilting of the projecting end element (s) 12 to tilt in order to to obtain a rupture of the lid 3 releasing an effective amount of substance (S) in the contents of the container.

De manière particulièrement avantageuse, la surface d'appui 14 utile prévue sur l'élément arqué 15 présente sur sa face intérieure dirigée vers l'opercule 3, une portion de paroi verticale 17 ou sensiblement verticale également dirigée vers l'opercule 3 dont une surface d'appui auxiliaire non représentée assiste la transmission de l'effort mécanique extérieur exercé sur ladite membrane déformable 2 par l'utilisateur pour provoquer ladite rupture de l'opercule 3.Particularly advantageously, the bearing surface 14 provided on the arched element 15 has on its inner face facing the lid 3, a vertical wall portion 17 or substantially vertical also directed towards the lid 3, a surface auxiliary support not shown assists the transmission of the external mechanical force exerted on said deformable membrane 2 by the user to cause said rupture of the lid 3.

Conformément à une autre caractéristique, l'anneau 7 périphérique et la ou les portions de charnière 9 et l'élément arqué 15 sont réalisés d'un seul tenant, de préférence par injection d'un matériau synthétique.According to another characteristic, the peripheral ring 7 and the hinge portion or portions 9 and the arcuate element 15 are made in one piece, preferably by injection of a synthetic material.

Enfin, il peut également être prévu, si nécessaire, de munir l'opercule 3 prévu dans les capsules 1 en outre d'au moins un point ou une ligne de rupture préférentielle, par exemple sous la forme d'une prédécoupe, ce afin de faciliter encore, en combinaison avec les moyens de rupture 4 susvisés, la rupture dudit opercule 3.Finally, it may also be provided, if necessary, to provide the lid 3 provided in the capsules 1 in addition to at least one point or a preferred line of rupture, for example in the form of a precut, in order to further facilitate, in combination with the aforementioned breaking means 4, the rupture of said seal 3.

On peut ainsi prévoir une ou plusieurs rainures où l'épaisseur de l'opercule 3 a été volontairement réduite tel que par ablation laser ou un procédé similaire ou équivalent.One or more grooves may thus be provided in which the thickness of the lid 3 has been voluntarily reduced, such as by laser ablation or a similar method or equivalent.

En ce qui concerne l'assemblage des différentes parties constitutives de la capsule, une première solution consiste à faire en sorte que l'opercule 3 soit fixé directement sur la membrane déformable 2, de préférence au niveau de leur périphérie circulaire commune où ledit opercule 3 et ladite membrane déformable 2 se contactent en se chevauchant.As regards the assembly of the various constituent parts of the capsule, a first solution consists in ensuring that the lid 3 is fixed directly on the deformable membrane 2, preferably at their common circular periphery where said lid 3 and said deformable membrane 2 contact each other overlappingly.

Cette première possibilité est exemplifiée par la figure 1. Dans le mode de réalisation illustré à la figure 1, par exemple, l'élément arqué 15 et l'anneau 7 sont réalisés d'un seul tenant sous la forme d'une pièce monobloc qui peut être insérée librement (sans soudure) dans le creux formé par la membrane déformable 2 lors de la fabrication de la capsule 1. L'opercule 3 est alors directement soudé sur la portion périphérique correspondante de ladite membrane déformable 2, l'élément arqué 15 étant emprisonné entre ces derniers sans pour autant y être fixé. Le procédé de fabrication de la capsule 1 conforme à ce mode de réalisation s'en trouve donc avantageusement simplifié.This first possibility is exemplified by the figure 1 . In the embodiment illustrated in figure 1 for example, the arched element 15 and the ring 7 are made in one piece in the form of a single piece which can be inserted freely (without welding) in the hollow formed by the deformable membrane 2 during the Manufacture of the capsule 1. The lid 3 is then directly welded to the corresponding peripheral portion of said deformable membrane 2, the arched element 15 being trapped between them without being fixed there. The manufacturing process of the capsule 1 according to this embodiment is therefore advantageously simplified.

Selon une seconde possibilité, l'opercule 3 est fixé directement sur la face inférieure de la pièce intermédiaire 6, en particulier sur la face inférieure de la périphérie de l'anneau 7 formant ladite pièce intermédiaire 6, ce qui exclut alors un contact direct entre ledit opercule 3 et la membrane déformable 2.According to a second possibility, the cap 3 is fixed directly on the lower face of the intermediate piece 6, in particular on the lower face of the periphery of the ring 7 forming said intermediate piece 6, which then excludes direct contact between said lid 3 and the deformable membrane 2.

De façon avantageuse, l'opercule 3 est fixé par soudure circulaire, thermocontact circulaire ou par tout procédé similaire sur la membrane déformable 2 ou la face inférieure de la pièce intermédiaire 6.Advantageously, the cover 3 is fixed by circular welding, circular thermocontact or by any similar method on the deformable membrane 2 or the lower face of the intermediate part 6.

La présente invention a pour objet un bouchon pour récipient à goulot ou col destiné à la distribution de liquides ou de produits pâteux, en particulier pour bouteille d'eau minérale, essentiellement constitué par une embase 18 destinée à être fixée sur ledit récipient et fermant ledit récipient par l'intermédiaire d'une capsule 1 rapportée de manière étanche sur ladite embase 18, la membrane déformable 2 de ladite capsule 1 étant elle-même recouverte par un capot de protection 19 rigide reposant sur une pièce de base 20 annulaire rapportée sur ladite embase 18, la base inférieure de ladite capsule 1 étant formée par l'opercule 3 perçable, un volume utile étanche V rempli d'au moins une substance S destinée à être ajoutée au contenu du récipient avant consommation étant ainsi défini entre la membrane déformable 2 et ledit opercule 3 de ladite capsule 1, une quantité efficace de substance(s) S étant libérée dans le contenu du récipient lors d'une rupture de l'opercule 3 due à une déformation suffisante de la membrane déformable 2.The subject of the present invention is a stopper for a neck or neck container intended for dispensing liquids or pasty products, in particular for a bottle of mineral water, consisting essentially of a base 18 intended to be fixed on said container and closing said container. container via a capsule 1 reported in a sealed manner on said base 18, the deformable membrane 2 of said capsule 1 being itself covered by a rigid protective cover 19 resting on an annular base piece 20 attached to said base 18, the lower base of said capsule 1 being formed by the pierceable lid 3, a sealed effective volume V filled with at least one substance S intended to be added to the contents of the container before consumption being thus defined between the deformable membrane 2 and said lid 3 of said capsule 1, an effective amount of substance (S) being released into the contents of the container during a rupture of the lid 3 due to deformation sufficient deformable membrane 2.

Comme représenté aux figures 2 à 4, la capsule 1 comprend au moins une pièce intermédiaire 6 prévue entre ladite membrane déformable 2 et ledit opercule 3, ladite pièce intermédiaire 6 présentant ledit au moins un moyen de rupture 4 de ladite membrane déformable 2 qui peut être activé lors d'une déformation suffisante de cette dernière et en ce que la pièce intermédiaire 6 est réalisée sous la forme d'un anneau 7 périphérique sur lequel s'appuie localement, par l'intermédiaire d'une portion de charnière 9, un élément arqué 15 épousant sensiblement et au moins localement la forme de la membrane déformable 2 dans son état initial et dont l'extrémité libre 16 est réalisée sous la forme d'au moins un élément saillant 12 ou pointu dirigé vers l'opercule 3, une surface d'appui 14 utile étant prévue sur ledit élément arqué 15 qui est capable de transmettre un effort mécanique extérieur exercé sur ladite membrane déformable 2 par l'utilisateur qui est suffisant pour provoquer le basculement du ou des éléments saillants 12 d'extrémité afin d'obtenir une rupture de l'opercule 3 libérant une quantité efficace de substance(s) S contenue(s) dans ladite capsule 1.As represented in Figures 2 to 4 the capsule 1 comprises at least one intermediate piece 6 provided between said deformable membrane 2 and said lid 3, said intermediate piece 6 having said at least one breaking means 4 of said deformable membrane 2 which can be activated during a sufficient deformation of the latter and in that the intermediate part 6 is in the form of a peripheral ring 7 on which is supported locally, via a hinge portion 9, an arcuate element 15 substantially matching and at least locally the shape of the deformable membrane 2 in its initial state and whose free end 16 is formed in the form of at least one projecting element 12 or pointed towards the lid 3, a bearing surface 14 being provided provided on said arcuate element 15 which is capable of transmitting an external mechanical force exerted on said deformable membrane 2 by the user which is sufficient to cause the rocking end element or elements 12 in order to obtain a rupture of the lid 3 releasing an effective amount of substance (s) S contained in said capsule 1.

Préférentiellement, la membrane déformable 2 et le capot de protection 19 peuvent tous deux être réalisés en un matériau élastiquement déformable, sensiblement sous la forme de deux demi-sphères, le rayon de la demi-sphère du capot de protection 19 étant légèrement inférieur à celui de la demi-sphère de la membrane déformable 2, ladite demi-sphère du capot de protection 19 étant pourvue d'au moins une échancrure méridienne 19' s'étendant depuis la base de ladite demi-sphère sur une partie de la hauteur de celle-ci. Cette forme de réalisation du capot de protection 19 est particulièrement avantageuse car ce dernier ne nécessite pas d'être moulé en position d'ouverture, on réduit ainsi considérablement la taille du moule et on accroît sa résistance, ce qui permet de réduire de manière substantielle le coût de fabrication du capot de protection 19. De plus, du point de vue mécanique, le fait de ne pas mouler le capot de protection 19 en position ouverte permet également de préserver l'intégrité de la charnière 35 qui peut être affaiblie lors d'un moulage en position ouverte.Preferably, the deformable membrane 2 and the protective cover 19 may both be made of an elastically deformable material, substantially in the form of two half-spheres, the radius of the half-sphere of the protective cover 19 being slightly less than that of the half-sphere of the deformable membrane 2, said half-sphere of the protective cover 19 being provided with at least one meridian notch 19 'extending from the base of said half-sphere over part of the height of that -this. This embodiment of the protective cover 19 is particularly advantageous because the latter does not need to be molded in the open position, thus considerably reduces the size of the mold and increases its strength, which allows to reduce substantially the manufacturing cost of the protective cover 19. Moreover, from a mechanical point of view, the fact of not molding the protective cover 19 in the open position also makes it possible to preserve the integrity of the hinge 35, which can be weakened during molding in the open position.

La figure 2 représente le capot de protection 19 et la pièce de base 20 avant leur montage sur l'embase 18 dans le bouchon et la figure 3 représente le capot de protection 19 et l'embase 18 assemblés. Lors de cet assemblage, les échancrures méridiennes 19' s'élargissent et s'écartent les unes des autres pour le montage dudit capot de protection 19, de telle manière que sa dimension s'agrandisse pour sa fermeture sur l'embase 18, en collaboration avec les moyens d'ouverture et de fermeture 33 et 34.The figure 2 represents the protective cover 19 and the base part 20 before being mounted on the base 18 in the plug and the figure 3 represents the protective cover 19 and the base 18 assembled. During this assembly, the meridian notches 19 'widen and deviate from each other for the mounting of said protective cover 19, so that its dimension enlarges to close on the base 18, in collaboration with the opening and closing means 33 and 34.

Les exemples non limitatifs de bouchons selon l'invention susceptibles d'être munis d'une capsule 1 sont représentés aux figures 1 à 4.The nonlimiting examples of plugs according to the invention that may be provided with a capsule 1 are shown in FIGS. Figures 1 to 4 .

De manière avantageuse et comme on peut le voir par exemple sur les figures 2 et 3, le bouchon selon l'invention est caractérisé en ce que l'embase 18 est réalisée sous la forme d'une pièce constituée d'une partie cylindrique 21 destinée à être fixée sur le col ou le goulot du récipient munie, au niveau de son extrémité supérieure, d'une portion annulaire plate 22 formant un épaulement 23 circulaire interne délimitant une ouverture 24 dudit récipient, l'opercule 3 reposant ou étant fixé sur la face supérieure 22' de ladite portion annulaire plate 22 tournée vers la capsule 1.Advantageously and as can be seen for example on figures 2 and 3 , the plug according to the invention is characterized in that the base 18 is in the form of a part consisting of a cylindrical portion 21 intended to be fixed on the neck or the neck of the container provided, at its level. upper end, a flat annular portion 22 forming an inner circular shoulder 23 delimiting an opening 24 of said container, the cap 3 resting or being fixed on the upper face 22 'of said flat annular portion 22 facing the capsule 1.

L'embase 18 peut être réalisée en une pièce moulée, par exemple par injection, et sera préférentiellement réalisée en matière plastique.The base 18 may be made of a molded part, for example by injection, and will preferably be made of plastic.

L'embase 18 permet de fixer le bouchon sur le récipient et fournit en même temps la base pour la membrane déformable 2 et la pièce de base 20 du capot de protection 19 rigide recouvrant ladite membrane déformable 2.The base 18 makes it possible to fix the cap on the container and at the same time provides the base for the deformable membrane 2 and the base part 20 of the rigid protective cover 19 covering said deformable membrane 2.

Comme on le voit notamment sur les figures 1 à 3, le bouchon selon l'invention est encore caractérisé en ce que la face inférieure 22" de la portion annulaire plate 22 présente un décrochement vertical 25 sous la forme d'une jupe annulaire destinée à collaborer avec la face interne du col du récipient et la partie cylindrique 21 en vue de la fixation dudit bouchon sur ce dernier.As we see in particular on Figures 1 to 3 , the cap according to the invention is further characterized in that the lower face 22 "of the flat annular portion 22 has a vertical recess 25 in the form of an annular skirt intended to collaborate with the internal face of the neck of the container and the cylindrical portion 21 for fixing said cap on the latter.

Avantageusement, le bouchon selon l'invention (dans la variante représentée à la figure 1) est encore caractérisé en ce que la face supérieure 22' de la portion annulaire plate 22 est munie d'un rebord annulaire 26 au moins légèrement déformable formant, après montage de la capsule 1 dans ledit bouchon, une gorge annulaire avec ladite portion annulaire plate 22 emprisonnant la partie périphérique de la capsule 1, au niveau de l'opercule 3 et de la membrane déformable 2 et, le cas échéant, de la pièce intermédiaire 6.Advantageously, the plug according to the invention (in the variant shown in FIG. figure 1 ) is further characterized in that the upper face 22 'of the flat annular portion 22 is provided with an annular flange 26 at least slightly deformable forming, after mounting the capsule 1 in said cap, an annular groove with said flat annular portion 22 imprisoning the peripheral part of capsule 1, at level of the lid 3 and the deformable membrane 2 and, if appropriate, the intermediate piece 6.

De cette manière, il devient possible de parfaitement sceller ladite membrane déformable 2 et de garantir l'étanchéité supérieure du volume étanche V. A cette fin, le rebord annulaire 26 est rabattu vers la portion annulaire plate 22 de l'embase 18 lors du montage de ladite membrane déformable 2. Ce sertissage de la membrane déformable 2 peut encore être renforcé par la partie annulaire plate 22 de la pièce de base 20 lorsque celle-ci est montée sur l'embase 18 en comprimant cette dernière comme expliqué ci-après.In this way, it becomes possible to perfectly seal said deformable membrane 2 and to ensure the upper tightness of the sealed volume V. To this end, the annular flange 26 is folded towards the flat annular portion 22 of the base 18 during assembly of said deformable membrane 2. This crimping of the deformable membrane 2 can be further reinforced by the flat annular portion 22 of the base part 20 when it is mounted on the base 18 by compressing the latter as explained below.

De manière préférée, le bouchon selon l'invention est en outre caractérisé en ce que la partie cylindrique 21 destinée à être fixée sur le col ou le goulot du récipient présente sur sa paroi circulaire latérale externe des moyens 28 destinés à coopérer avec des moyens complémentaires 29 situés sur la pièce de base 20 en vue d'assurer la fixation de la pièce de base 20 sur l'embase 18.Preferably, the plug according to the invention is further characterized in that the cylindrical portion 21 intended to be fixed on the neck or the neck of the container has on its outer lateral circular wall means 28 intended to cooperate with complementary means. 29 located on the base part 20 to ensure the attachment of the base part 20 on the base 18.

Ces moyens peuvent être tous les moyens mécaniques classiques adaptés de fixation.These means can be all the conventional mechanical means of attachment.

A titre d'exemple illustratif non limitatif, les moyens 28 et moyens complémentaires 29 sont réalisés, comme suggéré schématiquement sur la figure 1, par des éléments « femelles » tels que des encoches ou des rainures coopérant avec des éléments « mâles » comme, par exemple, des ergots ou bourrelets, etc.By way of nonlimiting illustrative example, the means 28 and complementary means 29 are produced, as suggested schematically on the figure 1 by "female" elements such as notches or grooves cooperating with "male" elements such as, for example, lugs or beads, etc.

Egalement de manière avantageuse, le bouchon selon l'invention est caractérisé en ce que la pièce de base 20 comprend un manchon cylindrique 30 destiné à être fixé sur l'embase 18 et muni, au niveau de son extrémité supérieure, d'une partie annulaire plate 31 formant un rebord circulaire 32 interne destiné à venir s'appuyer, de préférence en le comprimant, sur le rebord annulaire 26 qui emprisonne la partie périphérique de la capsule 1, au niveau de l'opercule 3 et de la membrane déformable 2 et, le cas échéant, de la pièce intermédiaire 6.Also advantageously, the stopper according to the invention is characterized in that the base part 20 comprises a cylindrical sleeve 30 intended to be fixed on the base 18 and provided, at its upper end, with an annular portion. plate 31 forming an inner circular rim 32 intended to bear, preferably by compressing, on the annular flange 26 which traps the peripheral portion of the capsule 1, at the level of the cap 3 and the deformable membrane 2 and , if any, of the intermediate piece 6.

Comme expliqué plus haut, cette mesure permet encore de renforcer avantageusement l'étanchéité supérieure entre la membrane déformable 2 et l'embase 18 du bouchon.As explained above, this measure further advantageously reinforces the upper seal between the deformable membrane 2 and the base 18 of the plug.

Alternativement, le manchon cylindrique 30 de la pièce de base 20 peut être fixé directement, par tout moyen habituel (soudure, collage...) sur la membrane déformable 2 de la capsule 1 qui repose et/ou qui est fixée à son tour sur l'embase 18, éventuellement par l'intermédiaire de l'opercule 3. Ainsi ledit manchon cylindrique 30 peut venir en butée mécanique lorsque le capot de protection 19 est assemblé avec l'embase 18 et être fixé au niveau de cette butée et/ou latéralement au niveau de la périphérie cylindrique de ladite embase 18 (cf. figure 3).Alternatively, the cylindrical sleeve 30 of the base part 20 can be fixed directly, by any usual means (welding, bonding ...) on the deformable membrane 2 of the capsule 1 which rests and / or which is fixed in turn on the base 18, possibly via the cover 3. Thus said cylindrical sleeve 30 can come into mechanical abutment when the protective cover 19 is assembled with the base 18 and be fixed at this level. stop and / or laterally at the cylindrical periphery of said base 18 (cf. figure 3 ).

Le bouchon selon l'invention peut être fixé sur le goulot d'un récipient par tout moyen habituel. De manière préférée, ledit bouchon est vissé sur le goulot dudit récipient.The plug according to the invention can be fixed on the neck of a container by any usual means. Preferably, said cap is screwed onto the neck of said container.

Dans ce dernier cas, on peut prévoir comme représenté sur les figures 1 à 3, que la partie cylindrique 21 est réalisée sous la forme d'un manchon cylindrique muni d'un filetage interne 21' destiné au vissage sur le filetage externe du col ou goulot fileté du récipient.In the latter case, it can be Figures 1 to 3 , that the cylindrical portion 21 is in the form of a cylindrical sleeve provided with an internal thread 21 'for screwing on the external thread of the neck or neck of the container.

De cette manière, le bouchon conforme à la présente invention pourra être monté sur tout récipient muni d'un filetage standard.In this way, the plug according to the present invention can be mounted on any container with a standard thread.

Selon une autre caractéristique, la pièce de base 20 présente un premier moyen d'ouverture et de fermeture 33 destiné à coopérer par enclenchement par déformation élastique avec un second moyen correspondant 34 situé sur le capot de protection 19.According to another characteristic, the base part 20 has a first opening and closing means 33 intended to cooperate by engagement by elastic deformation with a second corresponding means 34 located on the protective cover 19.

De façon générale tout dispositif du type mâle-femelle ou analogue peut être adapté au présent bouchon afin de garantir une fermeture fiable et facilement déblocable du capot de protection 19.In general, any device of the male-female or similar type can be adapted to the present plug in order to guarantee a reliable and easily unlockable closure of the protective cover 19.

Selon une première variante, la pièce de base 20 présente un bouton poussoir muni d'un premier crochet destiné à coopérer avec un second crochet correspondant situé sur le capot de protection 19.According to a first variant, the base part 20 has a push button provided with a first hook intended to cooperate with a corresponding second hook located on the protective cover 19.

Ainsi, il suffit d'appuyer, par exemple à l'aide du pouce, sur ledit bouton poussoir afin que les deux crochets précités se détachent, ce qui provoque l'ouverture dudit capot de protection 19 et l'accès à la membrane déformable 2.Thus, it is sufficient to press, for example with the thumb, said push button so that the two aforementioned hooks are detached, causing the opening of said protective cover 19 and access to the deformable membrane 2 .

Selon une autre variante, la pièce de base 20 présente un bouton poussoir muni d'un évidement destiné à coopérer avec un ergot correspondant situé sur le capot de protection 19.According to another variant, the base part 20 has a push button provided with a recess for cooperating with a corresponding pin located on the protective cover 19.

Afin de permettre le pivotement du capot de protection 19 lors de l'ouverture et la rétention de la partie pivotée il est avantageusement prévu que le capot de protection 19 soit relié à la pièce de base 20 par au moins une charnière de capot 35. Cette charnière 35 peut être réalisée sous différentes formes. A la figure 1, par exemple, ladite charnière 35 est réalisée sous la forme d'un simple élément injecté en matière synthétique et reliant la base du capot de protection 19 à la pièce de base 20.In order to allow the pivoting of the protective cover 19 during the opening and the retention of the pivoted part, it is advantageously provided that the protective cover 19 is connected to the base part 20 by at least one cover hinge 35. This hinge 35 can be made in different forms. To the figure 1 for example, said hinge 35 is realized in the form of a simple injected element made of synthetic material and connecting the base of the protective cover 19 to the base part 20.

La charnière 35 illustrée à la figure 4 et reliant le capot de protection 19 au niveau de son sommet à la pièce de base 20 est réalisée selon un mode particulier permettant audit capot d'être articulé ou pivoté au niveau du sommet de sa demi-sphère constitutive. Cette forme de réalisation du capot de protection 19 et de la charnière 35 permet de positionner le capot de protection 19 sur la pièce de base 20 afin de « l'écraser » contre ladite pièce de base 20, cet écrasement entraînant l'écartement des échancrures méridiennes 19' et l'enclenchement des moyens d'ouverture et de fermeture 33 et 34, comme cela est représenté sur la figure 4. Lorsque ces derniers sont enclenchés l'un dans l'autre, la position fermée du capot de protection 19 sur la pièce de base 20 est stabilisée.The hinge 35 illustrated at figure 4 and connecting the protective cover 19 at its top to the base part 20 is made according to a particular mode for said hood to be articulated or pivoted at the top of its constituent hemisphere. This embodiment of the protective cover 19 and the hinge 35 makes it possible to position the protective cover 19 on the base part 20 in order to "crush" it against said base part 20, this crushing resulting in the separation of the notches meridians 19 'and the engagement of the opening and closing means 33 and 34, as shown in FIG. figure 4 . When the latter are engaged one into the other, the closed position of the protective cover 19 on the base part 20 is stabilized.

Alternativement, on peut prévoir que le capot 19 ne soit pas fixé de manière permanente à la pièce de base 20 mais qu'il ne repose que sur cette dernière (par exemple en y étant enclenché par déformation élastique) et qu'il soit définitivement enlevé lors de l'utilisation ou de la consommation du contenu du récipient. En effet, le capot de protection 19 a pour vocation première de protéger la membrane déformable 2 de toute agression involontaire extérieure, par exemple lors des opérations de manutention, de stockage et de transport des récipients bouchés qui pourraient accidentellement la déformer ou l'endommager et rompre l'étanchéité du volume V.Alternatively, it can be provided that the cover 19 is not fixed permanently to the base part 20 but that it rests only on the latter (for example by being engaged by elastic deformation) and that it is permanently removed when using or consuming the contents of the container. Indeed, the protective cover 19 is intended primarily to protect the deformable membrane 2 from any involuntary external aggression, for example during handling operations, storage and transport of clogged containers that could accidentally deform or damage and break the tightness of volume V.

Dans un mode de réalisation particulièrement simple et économique, le capot de protection 19 est réalisé d'un seul tenant avec la pièce de base 20.In a particularly simple and economical embodiment, the protective cover 19 is made in one piece with the base part 20.

Selon une autre caractéristique, l'extrémité inférieure de l'embase 18 éloignée de la sortie du col ou goulot du récipient est munie d'une bague de sécurité 36.According to another feature, the lower end of the base 18 remote from the outlet of the neck or neck of the container is provided with a safety ring 36.

Elle permet de s'assurer que le bouchon n'a jamais été dévissé du goulot ou col du récipient.It ensures that the cap has never been unscrewed from the neck or neck of the container.

Par ailleurs, le bouchon selon l'invention est encore caractérisé en ce qu'il comporte, en outre, au moins un dispositif d'inviolabilité au niveau d'un moyen participant au verrouillage du capot de protection 19 en position fermée.Furthermore, the stopper according to the invention is further characterized in that it comprises, in addition, at least one tamper device at a means participating in locking the protective cover 19 in the closed position.

Un tel moyen peut par exemple être réalisé sous la forme d'un anneau ou d'une bande circulaire de film en un matériau thermoplastique thermoformé qui épouse et recouvre, avant la première utilisation, ledit moyen de verrouillage du capot de protection. Cette bande est arrachée lors de la première utilisation, par exemple, grâce à un moyen facilitant cet enlèvement tel qu'une portion prédécoupée (en pointillés), une encoche d'arrachage, un fil d'ouverture, etc. et sert donc de témoin d'ouverture du bouchon en question.Such a means may for example be made in the form of a ring or a circular band of film made of a thermoformed thermoplastic material that marries and covers, before the first use, said locking means of the protective cover. This band is torn off during the first use, for example, thanks to a means facilitating this removal such as a pre-cut portion (in dashed lines), a tear-off notch, an opening thread, etc. and thus serves as a witness opening the plug in question.

Selon une autre caractéristique avantageuse, le capot de protection 19 et la membrane déformable 2 sont réalisés en un ou des matériaux translucides, de préférence transparents.According to another advantageous characteristic, the protective cover 19 and the deformable membrane 2 are made of one or more translucent materials, preferably transparent.

Ainsi, il est possible pour l'utilisateur de vérifier la présence de la substance S avant l'emploi, par exemple la présence d'un comprimé tel qu'un médicament bien précis devant être dissous dans le contenu du récipient avant ingestion. Il permet également, dans le cas où l'on utilise des matériaux transparents, de contrôler la nature de la substance S, par exemple au moyen d'un code de couleur ou de forme. On peut ainsi imaginer une substance S colorée selon la nature de son goût qui peut être additionnée à une boisson ne présentant pas ou relativement peu de goût ou un goût devant être modifié, soit renforcé ou au contraire atténué voire masqué.Thus, it is possible for the user to check the presence of the substance S before use, for example the presence of a tablet such as a specific drug to be dissolved in the contents of the container before ingestion. It also allows, in the case where using transparent materials, to control the nature of the substance S, for example by means of a color code or shape. One can thus imagine a substance S colored according to the nature of its taste that can be added to a beverage with no or relatively little taste or a taste to be modified, either reinforced or on the contrary attenuated or even masked.

A titre d'exemple non limitatif, la substance S peut être une poudre, une pastille ou un sirop colorés destinés à être dissous dans de l'eau minérale, chaque couleur correspondant à un goût ou une autre caractéristique prédéfinie (jaune = citron, rouge = pomme, vert = citron-vert, orange = mandarine ou orange, marron = chocolat, bleu = mentholé, noir = cola...).By way of non-limiting example, the substance S can be a powder, a tablet or a colored syrup intended to be dissolved in mineral water, each color corresponding to a taste or another predefined characteristic (yellow = lemon, red = apple, green = lime-green, orange = tangerine or orange, brown = chocolate, blue = menthol, black = cola ...).

Enfin, la réalisation transparente permet également d'augmenter l'aspect esthétique et ludique du bouchon selon l'invention.Finally, the transparent embodiment also makes it possible to increase the aesthetic and playful appearance of the cap according to the invention.

De la manière la plus générale, la ou les substances S peuvent être n'importe quelle substance alimentaire ou non (quel que soit son état : solide, liquide, gazeuse, pâteuse etc.) ou mélange de substances que l'on peut souhaiter ajouter au contenu du récipient, ledit contenu pouvant également être n'importe quel contenu alimentaire ou non, ce également indépendamment de son état physique.In the most general manner, the substance or substances S can be any food substance or not (whatever its state: solid, liquid, gaseous, pasty, etc.) or mixture of substances that may be added the contents of the container, said content can also be any food content or not, also regardless of its physical state.

Préférentiellement, la ou les substances S sont des solides ou des liquides et le contenu du récipient est un liquide plus ou moins visqueux, de préférence de l'eau et encore plus préférentiellement de l'eau minérale.Preferably, the substance or substances S are solids or liquids and the contents of the container is a liquid more or less viscous, preferably water and even more preferably mineral water.

De préférence, la ou les substances S et le contenu du récipient sont de nature alimentaire, c'est-à-dire non toxiques pour l'homme ou les animaux.Preferably, the substance or substances S and the contents of the container are of food type, that is to say non-toxic to humans or animals.

Bien que l'exemple non limitatif du présent exposé soit donné pour une substance S solide et un contenu du récipient liquide, il va de soi que l'homme du métier saura adapter ce dernier à d'autres cas non explicitement décrits ici, en prévoyant les aménagements d'usage en ce qui concerne la nature des matériaux employés, les dimensions des différentes pièces...Although the nonlimiting example of the present disclosure is given for a solid substance S and a content of the liquid container, it goes without saying that a person skilled in the art will be able to adapt the latter to other cases not explicitly described here, by providing the usual adaptations with regard to the nature of the materials used, the dimensions of the different rooms ...

Le terme « ajouté » concernant ladite ou lesdites substances doit également s'entendre comme incluant l'adjonction pure et simple, c'est-à-dire le simple fait d'additionner ladite ou lesdites substances S (par exemple insolubles) au contenu du récipient, mais également leur mélange physique (assisté ou non) pour en former un mélange stable, une suspension, une émulsion, etc., leur dissolution partielle ou complète dans ledit contenu, et leur mélange chimique (entraînant une ou plusieurs réactions chimiques).The term "added" to the said substance or substances must also be understood to include the addition of pure and simple, that is to say the simple fact of adding said substance or substances (for example, insoluble) to the content of the substance. container, but also their physical mixture (assisted or not) to form a stable mixture, a suspension, an emulsion, etc., their partial or complete dissolution in said content, and their chemical mixture (resulting in one or more chemical reactions).

De manière avantageuse, la ou les substances S comprennent au moins une substance sensible au contenu du récipient avec lequel la capsule 1 est destinée à collaborer et ne devant être ajoutée à ce dernier que peu de temps ou juste avant sa consommation.Advantageously, the substance or substances S comprise at least one substance sensitive to the contents of the container with which the capsule 1 is intended to collaborate and not to be added thereto for a short time or just before consumption.

Des exemples non limitatifs d'une telle substance S sont des préparations médicales dans lesquelles le composé actif est très fragile et doit être mis sous sa forme administrable à la dernière minute, les mélanges physiquement ou chimiquement peu stables dans le temps (substances non miscibles, denrées périssables), etc.Non-limiting examples of such a substance S are medical preparations in which the active compound is very fragile and must be put into its form that can be administered at the last minute, the mixtures being physically or chemically not very stable over time (immiscible substances, perishable goods), etc.

Ainsi, la ou les substances S comprennent au moins un médicament, ou au moins un agent cosmétique buvable, par exemple une solution de collagène buvable.Thus, the substance or substances S comprise at least one drug, or at least one drinkable cosmetic agent, for example a solution of oral collagen.

Comme évoqué plus haut, la substance ou les substances S sont préférentiellement de nature alimentaire.As mentioned above, the substance or substances S are preferably of a food nature.

Avantageusement, la ou les substances S peuvent être choisies dans le groupe formé par: les colorants, les arômes, les agents conservateurs, les édulcorants, les agents épaississants, les stabilisants, les alicaments, les compléments nutritionnels ou diététiques ou toute composition obtenue à partir d'au moins deux de ces ingrédients.Advantageously, the substance or substances S may be chosen from the group formed by: dyes, flavors, preserving agents, sweeteners, thickeners, stabilizers, nutraceuticals, dietary supplements or any composition obtained from at least two of these ingredients.

Par alicament on entend tout aliment considéré comme particulièrement bénéfique pour la santé (produits laitiers ou à base de céréales, fibres...).By food is meant any food considered particularly beneficial for health (dairy products or cereals, fiber ...).

Enfin, la substance ou les substances S peuvent comprendre au moins une substance solide, éventuellement réduite sous forme de poudre ou de granulés.Finally, the substance or substances S may comprise at least one solid substance, optionally reduced in the form of powder or granules.

Comme représenté sur les figures 1 à 4, la capsule 1, voire le bouchon muni d'une telle capsule 1, présentent une forme extérieure arrondie sensiblement en forme de demi-sphère, éventuellement légèrement aplatie.As shown on Figures 1 to 4 , the capsule 1, or the plug provided with such a capsule 1, have a rounded outer shape substantially half-sphere shape, possibly slightly flattened.

Grâce à ces formes arrondies ergonomiques, la manipulation des récipients ainsi bouchés (prise en main, transport...), ainsi que leur aspect esthétique sont renforcés et les risques de blessures, en particulier chez les enfants, réduits.Thanks to these ergonomic rounded shapes, the handling of the containers thus plugged (grip, transport ...), as well as their aesthetic appearance are reinforced and the risk of injury, especially in children, reduced.

Selon une variante particulièrement intéressante, l'épaulement 23 circulaire interne délimitant une ouverture 24 dudit récipient bouché est pourvu sur une partie de sa périphérie interne d'au moins un élément en forme de dent, destiné à faciliter la rupture de l'opercule 3 perçable lors d'une déformation suffisante de la membrane déformable 2 de la capsule 1.According to a particularly advantageous variant, the inner circular shoulder 23 delimiting an opening 24 of said plugged container is provided on a part of its inner periphery with at least one tooth-shaped element intended to facilitate the rupture of the pierceable lid 3 during a sufficient deformation of the deformable membrane 2 of the capsule 1.

Alternativement, on peut prévoir un décrochement vertical 25 annulaire (de l'embase 18) pourvu d'une paire de bras parallèles 38, 38' s'étendant dans un plan parallèle à la surface de l'opercule 3 et prenant naissance sur la périphérie interne dudit décrochement vertical 25 en des points 39, 39' diamétralement opposés, lesdits bras 38, 38' étant de préférence reliés entre eux par un ponton 40 passant par le centre de l'ouverture 24, lesdits bras 38, 38' présentant chacun, au niveau de leurs extrémités, au moins un élément saillant sous la forme d'une pointe 41, 41' ou analogue dirigé vers la surface de l'opercule 3 et destiné à faciliter la rupture dudit opercule 3 perçable lors d'une déformation suffisante de la membrane déformable 2 de la capsule 1.Alternatively, an annular vertical recess (of the base 18) provided with a pair of parallel arms 38, 38 'extending in a plane parallel to the surface of the cover 3 and originating on the periphery can be provided. internal said vertical recess 25 at points 39, 39 'diametrically opposed, said arms 38, 38' being preferably interconnected by a pontoon 40 passing through the center of the opening 24, said arms 38, 38 'each having, at their ends, at least one projecting element in the form of a tip 41, 41 'or the like directed towards the surface of the lid 3 and intended to facilitate the breaking of said pierceable lid 3 during a sufficient deformation of the deformable membrane 2 of the capsule 1.

Cette réalisation particulière est représentée aux figures 5 à 8.This particular achievement is represented in Figures 5 to 8 .

Lors d'une fabrication par injection de la pièce en question, on pourra utiliser le ponton 40 comme lieu d'injection 1 de la matière plastique (cf. fig. 8).During manufacture by injection of the part in question, it will be possible to use the pontoon 40 as the place of injection 1 of the plastic material (cf. Fig. 8 ).

Lors d'une déformation suffisante de la membrane déformable 2 avec ou sans l'assistance notamment de la ou des substances S contenues dans le volume étanche V de la capsule 1, l'opercule 3 qui se situe au-dessus et à une distance de sécurité suffisante des pointes 41, 41' (pour éviter toute rupture accidentelle) est poussé vers le bas en direction de ces dernières qui le transpercent ou provoquent l'amorce de la rupture selon un point ou une ligne de rupture préférentielle pré-existante, de sorte à libérer une quantité suffisante de substance(s) S dans ledit récipient.During a sufficient deformation of the deformable membrane 2 with or without assistance including the substance or substances S contained in the sealed volume V of the capsule 1, the operculum 3 which is above and at a distance of sufficient security of the tips 41, 41 '(to avoid any accidental breakage) is pushed downwards towards the latter which pierce it or cause the beginning of the break at a pre-existing point or line of preferential rupture, so as to release a sufficient quantity of substance (s) S into said container.

Finalement, la présente invention a encore pour objet un récipient à goulot ou col destiné à la distribution de liquides ou de produits pâteux, en particulier d'eau minérale, caractérisé en ce qu'il comporte un bouchon selon la présente invention.Finally, the present invention also relates to a neck or neck container for dispensing liquids or pastes, in particular mineral water, characterized in that it comprises a cap according to the present invention.

Avantageusement, ledit récipient est caractérisé en ce que ladite capsule 1 est montée dans un bouchon conformément à la présente invention.Advantageously, said container is characterized in that said capsule 1 is mounted in a plug according to the present invention.

Pour verser ou boire directement au col ou au goulot du récipient la mixture issue du mélange de la ou des substances S avec le contenu du récipient, il suffit de dévisser complètement le bouchon pour permettre le passage de ladite mixture à travers l'ouverture 24 du récipient. Ce mode de réalisation est économique car il ne nécessite pas de rajout de pièce pour verser la mixture. De plus, le bouchon peut être vissé et dévissé à volonté sans altérer l'étanchéité du récipient, ce qui permet également de conserver ladite mixture dans le récipient, tout en garantissant une protection vis-à-vis de l'extérieur, du fait que la membrane déformable 2 est imperméable, même après sa déformation. On peut également prévoir un élément tel qu'une soupape au niveau de l'embase 18 pour permettre l'évacuation des gaz éventuellement formés lors du mélange de la substance S avec le contenant du récipient et s'accumulant dans le récipient (par exemple du CO2 pour des comprimés effervescents), et éviter ainsi un risque de surpression.To pour or drink directly to the neck or the neck of the container the mixture resulting from the mixture of the substance or substances S with the contents of the container, simply unscrew the cap completely to allow the passage of said mixture through the opening 24 of the container. This embodiment is economical because it does not require adding room to pour the mixture. In addition, the cap can be screwed and unscrewed at will without altering the tightness of the container, which also keeps the mixture in the container, while ensuring protection vis-à-vis the outside, the fact that the deformable membrane 2 is impermeable, even after deformation. It is also possible to provide an element such as a valve at the base 18 to allow the evacuation of any gases formed during the mixing of the substance S with the container of the container and accumulating in the container (for example CO 2 for effervescent tablets), and thus avoid the risk of overpressure.

Un accès ou un deuxième bouchon peut être également prévu sur la surface latérale du récipient pour permettre la distribution de ladite mixture. Cet accès ou deuxième bouchon peut présenter, en outre, un moyen de dégazage. Cette variante de réalisation est plus compliquée à mettre en oeuvre, et donc plus onéreuse. En outre, elle nécessite le rajout d'une pièce, ce qui entraîne une rupture de la symétrie du récipient et a pour effet de compliquer son entreposage et sa manutention.An access or a second stopper can also be provided on the lateral surface of the container to allow the distribution of said mixture. This access or second plug may further present a degassing means. This variant embodiment is more complicated to implement, and therefore more expensive. In addition, it requires the addition of a part, which causes a rupture of the symmetry of the container and has the effect of complicating storage and handling.

Bien entendu, l'invention n'est pas limitée aux modes de réalisations décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention défini par les revendications.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention as defined by the claims.
