Definitions
- the invention relates to a device for sealing the opening of containers and the purification treatment of ambient air therein by opening-closing cycles, these containers being intended for packaging sensitive products. gaseous pollutants in this ambient air.
- the sealing device and purification treatment being made of thermoplastic materials by the means of plastics, in one piece.
- caps to close containers whose essential function is to be desiccating: these particular containers are intended to receive and contain products sensitive to ambient humidity, products which must be protected by the creation of a dryest internal atmosphere possible, to avoid them a recovery of humidity, because such a recovery adsorption moisture could in particular react with said products by decreasing their reactivity, cause their mechanical fragility impact, disintegration or disintegration in the container.
- the products which are particularly sensitive to ambient humidity are numerous and can be more precisely, for example, medicinal test materials which are in powdery forms or in more elaborate forms such as granules, tablets, lozenges, oblong shape such as test strips or others, including those specifically that have a special sensitivity to moisture.
- These desiccant and waterproof containers of the state of the art for the storage of products sensitive to ambient humidity are of tubular shape or of another form and, provided with an orifice, are closed by a stopper secured or not of the tubular part by means of a securing means such as a narrow flexible band made of a polymer material identical to that of the container and the plug.
- desiccant and watertight containers are provided with internal desiccant means which are either a coating or an insert made by means of a desiccant thermoplastic polymer composition placed inside the containers on the inner surface of the bottom of the tube and / or on the internal surface of the side wall of the tube, is still a granular desiccant material placed in a particular housing on the inner surface of the plug.
- desiccant means which are either a coating or an insert made by means of a desiccant thermoplastic polymer composition placed inside the containers on the inner surface of the bottom of the tube and / or on the internal surface of the side wall of the tube, is still a granular desiccant material placed in a particular housing on the inner surface of the plug.
- All these drying means are implanted separately or simultaneously to increase the effectiveness of their desiccant action by a mass effect.
- thermoplastic polymer compositions according to techniques well known in the plastics industry.
- Means for closing the containers and the desiccant containers closed by these means, for the packaging of materials and / or objects sensitive to ambient humidity, are described in the state of the art and are essentially distinguished from each other by their architecture, in particular by the desicative means used in said containers and by the architecture of the closure means of the container.
- this first type of closure is a male-type cap-lid connected to the tubular part of the envelope of the desiccant container by a means mechanical composed of a ring forcing said tubular casing and a flexible and narrow band connecting the cap-cover and the ring, the desiccant container being formed of a tubular casing open at one of its ends for give access to the receptacle area.
- this sealing means comprises a ring for force-fitting said cap-cover on the tubular casing of the container, and a flexible band acting as a narrow hinge connecting the cap-cover and said ring, the means shutter being made of a thermoplastic polymer material, which may be different from that of the tubular casing.
- This type of desiccant lid-cap for closing a tubular casing for the packaging of moisture-sensitive products presents uncertainties as to its ability to ensure rapid and complete desiccation of said products during the opening / closing of said packaging container. .
- This state of affairs seems to be, at least in part, the consequence of the flexible connection means between the cap-cap and the ring forcing the casing, this means which is a narrow flexible band made of polymer material acting as a hinge. not allowing adequate positioning at the time of closure of the envelope for lack of its prior guidance to said closure.
- this type of cap-lid requires a two-handed manipulation of the closed container, both for its opening and closure.
- this other type of closure is a female-type cap-lid, secured to the envelope of the desiccant container by a means consisting of a flexible and narrow connecting strip, the tubular casing, the cap-lid and the connecting means being made by injection with the same thermoplastic polymer material.
- EP 1 352 844 discloses such a type of means for closing the desiccant containers which is provided with a cap-cap, female type, free of downward inner skirt, which covers in closed position, the wall of the open end of the container casing .
- the cap-lid which has no downward peripheral inner skirt, can not establish a surface-to-surface seal with the inner surface of the open end of the tubular casing, the seal being able to only and apparently only be obtained by the contact of the surface internal of the bottom of the cap-lid and the periphery of the open end of the envelope.
- the cap-lid is not particularly adapted to the creation of sealing between the inside and the outside of the container, by its very architecture, but also by its means of flexible connection with the envelope, means that does not does not allow to position the lid at the time of its closure because of this great flexibility and therefore, the lack of sufficient mechanical rigidity both longitudinally and laterally, necessary to guide the cap-lid at the time of its closure.
- cap-lid requires two-handed manipulation of the closed container for both opening and closing.
- GB 2,224,309 discloses a hinged closure device, that is to say a thermoplastic container stopper and more particularly for containers having a very narrow, coaxial distribution orifice, intended for the distribution of liquid.
- the cap has on the inner surface of its upper end a tubular peripheral wall having a section adapted to that of the narrow dispensing orifice to be closed, and allowing, when the cap is in the closed position, to simultaneously ensure the tightness of the plug.
- Said device is composed of two parts, the first part being a click cover, pivoting on two hinges constituted by two flexible bands, defining a first axis of rotation, the second part being a base to be fixed on the mouth of a container to seal, and a flexible and elastic link, ensuring the connection between these two members and allowing the cap to occupy two rest positions, one closed and the other open, located on each side of an intermediate position during movement.
- Said flexible link having a return function, is in the form of "S" and is connected on one side to the plug at a precise point and on the other, to the external surface of the base at another precise point, and this, in a semi-rigid elastic manner.
- this device has certain disadvantages that may result from a form of embrittlement of the material constituting the flexible link.
- the "S" shape taken by the flexible link when the device moves from a closed position to an open position contributes to creating two opposing forces with respect to a point of inflection which lies substantially in the middle of the flexible link. this inflection point delimiting downstream a convex blade zone and upstream a blade zone which remains concave.
- the inversion of slope due to the "S" deformation creates, during closing, an acceleration of the movement taking effect on the convex part of the blade, ie between the cover and the point of inflection. , to restore the concave stable initial state of the entire blade.

Ces conteneurs clos sont formés :
- ■ d'une enveloppe tubulaire munie d'un fond à l'une des extrémités, l'autre extrémité étant ouverte pour permettre le remplissage de ladite enveloppe,
- ■ et d'un moyen de fermeture qui peut être un bouchon amovible s'emboîtant dans l'extrémité ouverte de l'enveloppe tubulaire, ou encore un bouchon-couvercle s'emboîtant également dans l'extrémité ouverte, mais relié à l'enveloppe tubulaire par une liaison souple telle qu'une bande souple étroite en polymère faisant office de charnière.
- A tubular casing provided with a bottom at one end, the other end being open to allow filling of said casing,

Des moyens d'obturation des conteneurs et les conteneurs dessicatifs clos par ces moyens, pour lé conditionnement de matériaux et/ou objets sensibles à l'humidité ambiante, sont décrits dans l'état de la technique et se distinguent essentiellement les uns des autres par leur architecture, en particulier par les moyens dessicatifs mis en oeuvre dans lesdits conteneurs et par l'architecture du moyen de fermeture du conteneur.Means for closing the containers and the desiccant containers closed by these means, for the packaging of materials and / or objects sensitive to ambient humidity, are described in the state of the art and are essentially distinguished from each other by their architecture, in particular by the desicative means used in said containers and by the architecture of the closure means of the container.
Selon un premier type de moyen d'obturation de conteneurs dessicatifs issu de l'état de la technique, ce premier type d'obturation est un bouchon-couvercle de type mâle relié à la partie tubulaire de l'enveloppe du conteneur dessicatif par un moyen mécanique composé d'une bague cerclant à force ladite enveloppe tubulaire et d'une bande souple et étroite de liaison entre le bouchon-couvercle et la bague, le conteneur dessicatif étant formé d'une enveloppe tubulaire ouverte à l'une de ses extrémités pour donner accès à la zone réceptacle.According to a first type of desiccant container sealing means resulting from the state of the art, this first type of closure is a male-type cap-lid connected to the tubular part of the envelope of the desiccant container by a means mechanical composed of a ring forcing said tubular casing and a flexible and narrow band connecting the cap-cover and the ring, the desiccant container being formed of a tubular casing open at one of its ends for give access to the receptacle area.
Ce type de bouchon-couvercle dessicatif destiné à clore une enveloppe tubulaire servant au conditionnement de produits sensibles à l'humidité présente des incertitudes quant à sa capacité à assurer une dessiccation rapide et complète desdits produits lors de l'ouverture/fermeture dudit conteneur de conditionnement. Cet état de fait semble être, au moins pour partie, la conséquence du moyen de liaison souple entre le couvercle-bouchon et la bague cerclant à force l'enveloppe, ce moyen qui est une bande souple étroite en matériau polymère faisant office de charnière ne permettant pas un positionnement adéquat au moment de la fermeture de l'enveloppe par absence de son guidage préalable à ladite fermeture.This type of desiccant lid-cap for closing a tubular casing for the packaging of moisture-sensitive products presents uncertainties as to its ability to ensure rapid and complete desiccation of said products during the opening / closing of said packaging container. . This state of affairs seems to be, at least in part, the consequence of the flexible connection means between the cap-cap and the ring forcing the casing, this means which is a narrow flexible band made of polymer material acting as a hinge. not allowing adequate positioning at the time of closure of the envelope for lack of its prior guidance to said closure.
En outre, ce type de bouchon-couvercle nécessite une manipulation à deux mains du conteneur clos, aussi bien pour son ouverture que sa fermeture.In addition, this type of cap-lid requires a two-handed manipulation of the closed container, both for its opening and closure.
Selon un autre type de moyen d'obturation de conteneurs dessicatifs issus dé l'état de la technique, cet autre type d'obturation est un bouchon-couvercle de type femelle, solidaire de l'enveloppe du conteneur dessicatif par un moyen constitué d'une bande de liaison souple et étroite, l'enveloppe tubulaire, le bouchon-couvercle et le moyen de liaison étant réalisé par injection avec le même matériau polymère thermoplastique.According to another type of desiccant container sealing means from the state of the art, this other type of closure is a female-type cap-lid, secured to the envelope of the desiccant container by a means consisting of a flexible and narrow connecting strip, the tubular casing, the cap-lid and the connecting means being made by injection with the same thermoplastic polymer material.
Le bouchon-couvercle démuni d'une jupe interne périphérique descendante, ne peut établir une étanchéité de type surface à surface avec la surface interne de l'extrémité ouverte de l'enveloppe tubulaire, l'étanchéité ne pouvant seulement et apparemment être obtenue que par le contact de la surface interne du fond du bouchon-couvercle et la périphérie de l'extrémité ouverte de l'enveloppe.The cap-lid, which has no downward peripheral inner skirt, can not establish a surface-to-surface seal with the inner surface of the open end of the tubular casing, the seal being able to only and apparently only be obtained by the contact of the surface internal of the bottom of the cap-lid and the periphery of the open end of the envelope.
Le bouchon-couvercle n'est pas particulièrement adapté à la création d'étanchéité entre l'intérieur et l'extérieur du conteneur, de par son architecture même, mais aussi de par son moyen de liaison souple avec l'enveloppe, moyen qui ne permet pas de positionner le couvercle au moment de sa fermeture en raison de cette grande souplesse et dès lors, de l'absence d'une rigidité mécanique suffisante aussi bien longitudinalement que latéralement, nécessaire au guidage du bouchon-couvercle au moment de sa fermeture.The cap-lid is not particularly adapted to the creation of sealing between the inside and the outside of the container, by its very architecture, but also by its means of flexible connection with the envelope, means that does not does not allow to position the lid at the time of its closure because of this great flexibility and therefore, the lack of sufficient mechanical rigidity both longitudinally and laterally, necessary to guide the cap-lid at the time of its closure.
En plus, le bouchon-couvercle nécessite une manipulation à deux mains du conteneur clos aussi bien pour son ouverture que sa fermeture.In addition, the cap-lid requires two-handed manipulation of the closed container for both opening and closing.
Ledit dispositif se compose de deux parties, la première partie étant un couvercle à déclic, pivotant sur deux charnières constituées par deux bandes flexibles, définissant un premier axe de rotation, la deuxième partie étant une base à fixer sur l'embouchure d'un conteneur à obturer, et un lien flexible et élastique, assurant la connexion entre ces deux membres et permettant au bouchon d'occuper deux positions de repos, l'une fermée et l'autre ouverte, situées de chaque coté d'une position intermédiaire lors du mouvement.Said device is composed of two parts, the first part being a click cover, pivoting on two hinges constituted by two flexible bands, defining a first axis of rotation, the second part being a base to be fixed on the mouth of a container to seal, and a flexible and elastic link, ensuring the connection between these two members and allowing the cap to occupy two rest positions, one closed and the other open, located on each side of an intermediate position during movement.
Ledit lien flexible, ayant une fonction de rappel, est en forme de "S" et est connecté d'un coté au bouchon en un point précis et de l'autre, à la surface externe de la base en un autre point précis, et ce, d'une manière élastique semi-rigide. La liaison entre les extrémités du lien flexible, d'une part sur le bouchon et d'autre part sur la surface externe de la base, est caractérisée par une absence de charnières, en raison de la continuité de l'épaisseur de la paroi.Said flexible link, having a return function, is in the form of "S" and is connected on one side to the plug at a precise point and on the other, to the external surface of the base at another precise point, and this, in a semi-rigid elastic manner. The connection between the ends of the flexible link, on the one hand on the cap and on the other hand on the outer surface of the base, is characterized by an absence of hinges, due to the continuity of the thickness of the wall.
Cependant, ce dispositif comporte certains inconvénients qui peuvent résulter d'une forme de fragilisation du matériau constituant le lien flexible. En effet, la forme en "S" prise par le lien flexible lorsque le dispositif passe d'une position fermée à une position ouverte contribue à créer deux forces antagonistes par rapport à un point d'inflexion qui se situe sensiblement au milieu du lien flexible, ce point d'inflexion délimitant en aval une zone de lame convexe et en amont une zone de lame qui reste concave.However, this device has certain disadvantages that may result from a form of embrittlement of the material constituting the flexible link. Indeed, the "S" shape taken by the flexible link when the device moves from a closed position to an open position contributes to creating two opposing forces with respect to a point of inflection which lies substantially in the middle of the flexible link. this inflection point delimiting downstream a convex blade zone and upstream a blade zone which remains concave.
Ainsi, l'inversion de pente due à la déformation en "S" crée, lors de la fermeture, une accélération du mouvement prenant effet sur la partie convexe de la lame, c'est à dire entre le couvercle et le point d'inflexion, pour rétablir l'état initial stable concave de la totalité de la lame.Thus, the inversion of slope due to the "S" deformation creates, during closing, an acceleration of the movement taking effect on the convex part of the blade, ie between the cover and the point of inflection. , to restore the concave stable initial state of the entire blade.
Ce type de lien flexible assurant la fonction de rappel subit donc une déformation par inversion de pente sur toute sa longueur, cette mobilisation mécanique totale et constante de la matière constitutive du lien flexible lui procurant de la fragilité.This type of flexible link providing the return function therefore undergoes deformation by inversion of slope over its entire length, this total and constant mechanical mobilization of the constituent material of the flexible link providing fragility.
La jupe est muni d'un anneau protubérant présentant une surface externe et le capuchon est muni d'un anneau protubérant présentant une surface interne. Les deux surfaces se touchent pour obtenir l'étanchéité. Dans la position fermée du dispositif, les charnières-films dépassent la surface externe de la jupe et du capuchon. Entre les deux charnières-films le dispositif est muni d'une nervure à effet ressort. Dû au contact surface à surface et au placement des charnières-films le dispositif doit être moulé dans sa position ouverte.The skirt is provided with a protruding ring having an outer surface and the cap is provided with a protruding ring having an inner surface. Both surfaces touch each other to achieve a seal. In the closed position of the device, the film hinges protrude from the outer surface of the skirt and cap. Between the two film hinges the device is provided with a spring rib. Due to the surface-to-surface contact and the placement of the film hinges, the device must be molded in its open position.
Ainsi il apparaît qu'aucun des bouchons-couvercles dessicatifs de l'état de la technique ne dispose des moyens suffisants de pouvoir avec une seule main manipuler facilement lesdits bouchons-couvercles et de tenir le conteneur obturé et également assister mécaniquement l'ouverture/fermeture du bouchon-couvercle, ainsi qu'un réalisation en une seule pièce selon les méthodes de la plasturgie dans la position fermée.Thus it appears that none of the desiccant lid-caps of the state of the art has sufficient means of power with one hand to easily handle said caps-lids and to hold the container closed and also to assist mechanically opening / closing cap-lid, and a realization in one piece according to the methods of the plastics in the closed position.
L'objectif énoncé précédemment peut être atteint par le dispositif pour l'obturation étanche de conteneurs et de traitement de purification de l'air ambiant récité dans la revendication 1 ci-dessous. Des modes avantageuses de réalisation sont.définis dans les revendications dépendantes.The above stated objective can be achieved by the device for container sealing and ambient air purification treatment recited in
Selon l'invention, le moyen d'obturation et de traitement de purification créé pour le conteneur est de type mâle. Son architecture lui assure une zone périphérique de contact intime avec la surface interne de l'enveloppe tubulaire constituant l'orifice du conteneur à clore, cette zone de contact périphérique intime, de type surface à surface, formant une barrière efficace pour l'obtention et le maintien de l'étanchéité interne du conteneur.According to the invention, the sealing means and purification treatment created for the container is of the male type. Its architecture ensures a peripheral zone of intimate contact with the inner surface of the tubular envelope constituting the opening of the container to be closed, this zone of intimate peripheral contact, of surface-to-surface type, forming an effective barrier for obtaining and maintaining the internal tightness of the container.
Pour ce faire, le moyen d'obturation choisi est du type bouchon- couvercle, comportant une paroi d'extrémité supérieure constituant le plafond du bouchon-couvercle ayant une section adaptée à celle de l'enveloppe tubulaire qu'elle doit clore. Cette paroi d'extrémité supérieure est munie de deux parois, l'une dite externe et l'autre dite interne, qui sont périphériques et tubulaires, concentriques et coaxiales à l'enveloppe tubulaire.To do this, the closure means chosen is of the cap-lid type, comprising an upper end wall constituting the ceiling of the cap-lid having a section adapted to that of the tubular casing which it must close. This upper end wall is provided with two walls, one said external and the other said internal, which are peripheral and tubular, concentric and coaxial with the tubular casing.
La première paroi dite paroi externe, périphérique et tubulaire, crée une zone de contact périphérique intime pour l'obtention de l'étanchéité, de type surface à surface, par l'établissement d'une barrière d'étanchéité entre la face interne de l'enveloppe tubulaire de l'orifice d'accès et la face externe de ladite première paroi, dite paroi externe, du bouchon-couvercle.The first so-called outer wall, peripheral and tubular, creates an intimate peripheral contact area for obtaining the seal, surface-to-surface type, by establishing a sealing barrier between the inner face of the tubular casing of the access orifice and the outer face of said first wall, said outer wall, of the cap-lid.
La forme en coupe de cette première paroi, dite paroi externe, révèle un renflement périphérique, orienté vers l'extérieur, et destiné à être au contact de la paroi interne de l'enveloppe tubulaire de l'orifice du conteneur.The sectional shape of this first wall, said outer wall, reveals a peripheral bulge, oriented outwards, and intended to be in contact with the inner wall of the tubular casing of the orifice of the container.
Lorsque le moyen d'obturation ou bouchon-couvercle se place en position fermée, le renflement périphérique de la première paroi, dite paroi externe, arrive au contact à force de la surface interne de l'enveloppe tubulaire de l'orifice, en subissant préférentiellement un certain effet de déformation ou d'écrasement qui provoque une augmentation de la surface de contact du renflement périphérique avec la surface interne de l'enveloppe tubulaire de l'orifice du conteneur de telle sorte que le contact surface à surface qui est d'abord tangentiel puisse devenir intime et immédiat à la fermeture par une augmentation de la surface de contact qui découle du glissement et de l'écrasement d'une paroi sur l'autre renforçant l'étanchéité entre le dispositif d'obturation et le conteneur.When the closure means or cap-lid is placed in closed position, the peripheral bulge of the first wall, said outer wall, comes into force contact with the inner surface of the tubular casing of the orifice, while undergoing preferably a certain deformation or crushing effect which causes an increase in the contact area of the peripheral bulge with the inner surface of the tubular casing of the container orifice so that the surface-to-surface contact which is tangential approach can become intimate and immediate closure by an increase in the contact area that results from the sliding and crushing of a wall on the other reinforcing the seal between the closure device and the container.
Dès lors, s'établit entre l'intérieur et l'extérieur du conteneur clos par le moyen d'obturation selon l'invention, une étanchéité efficace.Therefore, is established between the inside and outside of the closed container by the sealing means according to the invention, an effective seal.
La deuxième paroi, dite paroi interne, périphérique et préférentiellement tubulaire, constitue un logement approprié pour recevoir un ou des agents de traitement de purification, la position particulière de ce logement étant déterminante pour augmenter la cinétique de traitement des agents polluants gazeux et en particulier la vapeur d'eau.The second wall, referred to as the inner, peripheral and preferably tubular wall, constitutes an appropriate housing for receiving one or more purification treatment agents, the particular position of this housing being decisive for increasing the kinetics of treatment of the gaseous pollutants and in particular the water vapour.
Ce logement approprié, préférentiellement de type tubulaire, est situé sur la face interne du moyen d'obturation ou bouchon-couvercle, et est clos par un moyen de fermeture non étanche aux polluants gazeux pour assurer leur élimination rapide du conteneur où se trouvent conditionnés les produits sensibles à protéger.This appropriate housing, preferably tubular type, is located on the inner face of the closure means or cap-lid, and is closed by a closure means not sealed to gaseous pollutants to ensure their rapid elimination from the container where are packaged the sensitive products to protect.
Pour que le conteneur clos par le moyen d'obturation étanche et de traitement selon l'invention soit très efficacement dessicatif, dans le cas particulier du traitement de la vapeur d'eau, le choix de l'agent dessicatif est également déterminant.In order for the closed container by the sealing and treatment means according to the invention to be very effectively desiccative, in the particular case of the treatment of water vapor, the choice of the desiccant is also decisive.
L'agent dessicatif mis en oeuvre dans le conteneur clos par le moyen d'obturation étanche et de traitement, est choisi dans le groupe constitué par les gels de silice, les tamis moléculaires se présentant sous une forme pulvérulente ou déposés sur un support pulvérulent.The desiccant used in the closed container by the sealing and treatment means is selected from the group consisting of silica gels, the molecular sieves being in powder form or deposited on a powdery support.
Pour que le conteneur clos par le moyen d'obturation étanche et de traitement selon l'invention, soit également très efficace à l'égard des agents polluants gazeux autres que la vapeur d'eau, des agents de traitement connus appropriés à chaque agent polluant, sont mis en oeuvre dans le logement approprié créé sur le fond interne du moyen d'obturation étanche et de traitement:
- soit en mélange avec l'agent dessicatif,
- soit séparément de l'agent dessicatif en créant dans ce logement approprié des alvéoles ouvertes sectorisant ledit logement, permettant de recevoir séparément plusieurs agents de traitement ou des mélanges d'agents de traitement compatibles entre eux.
- either in admixture with the desiccant,
- or separately from the desiccant by creating in this appropriate housing open cells sectorizing said housing, for receiving separately several treatment agents or mixtures of treatment agents compatible with each other.
Pour faciliter la manoeuvre d'ouverture et de fermeture du bouchon- couvercle, le bord inférieur plan de la paroi périphérique externe peut être prolongé par une visière de préhension.To facilitate the operation of opening and closing the cover cap, the lower plane edge of the outer peripheral wall may be extended by a gripping visor.
Un système sécuritaire d'ouverture à l'égard des enfants en vue de leur rendre l'ouverture du bouchon-couvercle difficile voire impossible peut être installé au droit de la visière.
Ce dispositif qui peut être par exemple une lame souple faisant partie intégrante du moyen de montage se trouve placé en dessous de la visière de telle manière que le dépassement de la visière permettant d'exercer une poussée verticale pour en assumer son ouverture soit carénée par cette lame souple.A safe opening system for children in order to make it difficult or impossible for them to open the lid-cap can be installed on the right side of the visor.
This device which can be for example a flexible blade forming an integral part of the mounting means is located below the visor in such a way that the protrusion of the visor making it possible to exert a vertical thrust to assume its opening is careened by this flexible blade.
Dès lors l'accès à la visière ne peut se faire qu'après avoir exercé une pression sur cette lame en vue d'en provoquer la déformation et libérer l'accès à ladite visière. Par un tel moyen, la protection de l'enfant est assuré par la nécessaire réalisation de deux gestes complémentaires, et à exercer simultanément, le premier geste étant une pression horizontale sur la lame souple, le deuxième étant une action de poussée verticale de bas en haut sur la visière dégagée, grâce au maintien de la pression sur la lame souple.Therefore access to the visor can be done only after exerting pressure on the blade to cause deformation and release access to said visor. By such a means, the protection of the child is ensured by the necessary two complementary gestures to be performed, and to exercise simultaneously, the first gesture being a horizontal pressure on the flexible blade, the second being a vertical pushing action from below to high on the unobstructed visor, thanks to the maintenance of the pressure on the flexible blade.
Dès lors qu'il a été ouvert au moins une fois, pour maintenir le bouchon-couvercle en position fermée, la face interne de la paroi externe du bouchon-couvercle sensiblement au droit de la visière de préhension et la face externe de la paroi externe de l'enveloppe tubulaire de l'orifice d'accès du conteneur sont munies d'un moyen d'encliquetage, nécessitant un effort mécanique aussi bien pour achever la fermeture du bouchon- couvercle à étanchéité renforcée que pour assurer son ouverture.As soon as it has been opened at least once, in order to keep the cap-lid in the closed position, the inner face of the outer wall of the cap-lid substantially to the right of the gripping visor and the outer face of the outer wall of the tubular casing of the access port of the container are provided with a latching means, requiring a mechanical force as well to complete the closure of the lid tight-reinforced cover to ensure its opening.
Le moyen de montage du moyen d'obturation ou bouchon-couvercle, est formé d'une bague de fixation qui est montée sur l'enveloppe tubulaire de l'orifice d'accès au conteneur à obturer, cette bague :
- ayant un dimensionnement adapté à celui de l'enveloppe tubulaire,
- étant munie sur sa face interne, destinée à être au contact de la surface externe de l'enveloppe d'un moyen d'encliquetage en creux ou en relief, à l'égard de la face externe de l'enveloppe, sur laquelle le moyen permettant l'encliquetage de la bague est à l'opposé, c'est-à-dire en relief ou en creux.
- dans le cas où elle n'est pas munie sur sa surface interne d'un moyen d'encliquetage, étant strictement ajustée aux dimensions de l'enveloppe et implantée à force sur l'enveloppe, ou encore fixé par un moyen de collage.
- having a dimensioning adapted to that of the tubular envelope,
- being provided on its inner face, intended to be in contact with the outer surface of the casing of a recessed or raised snap-fastening means, with respect to the outer face of the casing, on which the means allowing the snap of the ring is the opposite, that is to say, raised or recessed.
- in the case where it is not provided on its inner surface with a detent means, being strictly adjusted to the dimensions of the casing and force-fitted on the casing, or fixed by a bonding means.
Selon une variante de l'invention, la surface périphérique externe de l'enveloppe tubulaire de l'orifice d'accès au conteneur à obturer comporte deux collerettes périphériques en saillie, séparées l'une de l'autre en créant une gorge présentant en coupe une forme sensiblement rectangulaire, de telle sorte que :
- l'épaisseur de l'enveloppe tubulaire à l'intérieur de la gorge n'est pas modifiée, et que
- la bague de fixation vient se monter à force dans ladite gorge.
- the thickness of the tubular casing inside the groove is not changed, and that
- the fixing ring is forced into said groove.
Selon une autre variante de l'invention, une gorge périphérique, pouvant présenter en coupe une forme sensiblement rectangulaire, hémisphérique ou hémielliptique, est réalisée en creux dans l'épaisseur de la paroi de l'enveloppe tubulaire du conteneur de telle sorte que :
- l'épaisseur de l'enveloppe tubulaire à l'intérieur de la gorge est modifiée, et est inférieure à celle de l'enveloppe tubulaire et que
- la bague de fixation vient se monter à force dans ladite gorge.
- the thickness of the tubular casing inside the groove is modified, and is less than that of the tubular casing and that
- the fixing ring is forced into said groove.
Selon une autre variante de l'invention, la surface interne de la bague de fixation présente des moyens d'encliquetage qui, lorsque ladite bague de fixation est monté à force dans la gorge de l'enveloppe tubulaire du conteneur, elle-même équipée de moyens d'encliquetage complémentaires, viennent s'encastrer dans les moyens d'encliquetage correspondant afin de bloquer toute rotation ou translation du bouchon par rapport au conteneur.According to another variant of the invention, the inner surface of the fixing ring has latching means which, when said fixing ring is force-fitted in the groove of the tubular casing of the container, itself equipped with complementary latching means, are embedded in the corresponding latching means to block any rotation or translation of the plug relative to the container.
Lesdits moyens d'encliquetage présents sur la surface interne de la bague de fixation et sur la surface interne de la gorge du conteneur peuvent être de divers types tels que des cannelures, des rainures ou autres.Said detent means present on the inner surface of the fixing ring and on the inner surface of the container groove may be of various types such as grooves, grooves or the like.
Selon l'invention, un moyen de liaison de type charnière relativement rigide, est présent entre le moyen d'obturation (ou bouchon-couvercle) et le moyen de montage (une bague de fixation) sur l'enveloppe tubulaire de l'orifice d'accès au conteneur.According to the invention, a relatively rigid hinge-type connection means is present between the closure means (or plug-cover) and the mounting means (a fixing ring) on the tubular casing of the orifice access to the container.
Le moyen de liaison de type charnière, selon l'invention, est formée de deux charnières-films espacées l'une de l'autre, et donnant de la rigidité à la liaison entre le bouchon-couvercle et la bague de fixation, en raison de leur espacement.The hinge type connecting means, according to the invention, is formed of two film hinges spaced from one another, and giving rigidity to the connection between the cap-cover and the fixing ring, due to their spacing.
Chaque charnière-film est formée de deux parties reliées entre elles par un film polymère jouant le rôle d'un axe de rotation permettant les cycles d'ouverture/fermeture du moyen d'obturation, l'une des parties étant intégrée au moyen d'obturation, l'autre partie étant intégrée au moyen de montage.Each film hinge is formed of two parts interconnected by a polymer film acting as an axis of rotation allowing the opening / closing cycles of the closure means, one of the parts being integrated by means of shutter, the other part being integrated in the mounting means.
Les deux parties de chacune des deux charnières intégrées au moyen d'obturation et au moyen de montage constituent des potences de fixation des deux charnières-film sur le moyen d'obturation et le moyen de montage.The two parts of each of the two hinges integrated in the closure means and the mounting means constitute brackets for fixing the two hinges-film on the closure means and the mounting means.
Ces deux types de charnière-film assurent le meilleur fonctionnement à la fermeture (de même qu'à l'ouverture) de la mise en place du bouchon-couvercle sur l'enveloppe de l'orifice à obturer par l'usage d'un seul doigt de la main tenant le conteneur, grâce à un guidage mécanique parfait dudit bouchon- couvercle, ne nécessitant, pour achever la fermeture, qu'une pression verticale du haut vers le bas, qui provoque l'encliquetage du bouchon-couvercle. Il faut préciser que les bouchons amovibles ou les bouchons-couvercles liés par une unique charnière-film à l'enveloppe tubulaire, nécessitent, pour leur fermeture ou leur ouverture, l'usage des deux mains.These two types of hinge-film ensure the best operation at closing (as well as opening) of the establishment of the cap-cover on the envelope of the orifice to be closed by the use of a only finger of the hand holding the container, thanks to a perfect mechanical guidance of said cap-lid, requiring, to complete the closure, a vertical pressure from top to bottom, which causes the snap-cap lid. It should be noted that removable plugs or caps-lids connected by a single hinge-film to the tubular casing, require, for their closure or opening, the use of both hands.
Ces deux charnières-films espacées l'une de l'autre constituent une charnière de précision pour la fermeture du bouchon-couvercle dessicatif puisque, grâce à la rigidité qu'elles créent par leur espacement, elles guident le bouchon-couvercle dessicatif jusqu'à sa fermeture complète selon une trajectoire parfaite, aboutissant à l'encliquetage du bouchon couvercle par simple pression verticale.These two film hinges spaced apart from each other constitute a precision hinge for closing the desiccant lid-cap since, thanks to the rigidity they create by their spacing, they guide the desiccant lid-lid up to its complete closure in a perfect trajectory, resulting in the snap of the lid cap by simple vertical pressure.
Le moyen d'inviolabilité ou encore témoin d'inviolabilité, est formée :
- soit de micro-liens reliant la surface périphérique inférieure du bouchon-couvercle à la surface périphérique supérieure de la bague de fixation, ces micro-liens étant des micro-points de liaison, indépendants les uns des autres mais formant une couronne dentée périphérique de liaison entre le moyen d'obturation dessicatif et le moyen de montage sur l'enveloppe tubulaire de l'orifice du conteneur, micro-points qui sont rompus lors de la première ouverture par l'application d'une force de rupture exercée sur la visière dans le sens du bas vers le haut,
- soit d'une bague d'inviolabilité à arracher reliant la surface périphérique inférieure du bouchon-couvercle à la surface périphérique supérieure à la bague de fixation,
- soit des deux moyens d'inviolabilité précités, formant une combinaison nouvelle de moyens d'inviolabilité.
- either micro-links connecting the lower peripheral surface of the cap-cover to the upper peripheral surface of the fixing ring, these micro-links being micro-points of connection, independent of each other but forming a peripheral ring gear connection between the desiccant sealing means and the mounting means on the tubular casing of the opening of the container, micro-points which are broken during the first opening by the application of a breaking force exerted on the visor in the direction from the bottom to the top,
- either a tamper-evident ring connecting the lower peripheral surface of the cap-cover to the upper peripheral surface to the fixing ring,
- either of the two aforementioned inviolability means, forming a new combination of inviolability means.
Un moyen mécanique à effet ressort pour l'assistance à l'ouverture ou la fermeture du moyen d'obturation étanche et de traitement, est placé dans l'espace situé entre les deux charnières-films précédemment évoquées. Ce moyen mécanique a l'aspect en coupe d'une équerre dont l'angle est de l'ordre de 90°.A mechanical spring means for assisting the opening or closing of the sealing means and treatment, is placed in the space between the two hinges-films previously mentioned. This mechanical means has the sectional appearance of a bracket whose angle is of the order of 90 °.
Ce moyen mécanique à effet ressort pour l'assistance à l'ouverture et la fermeture du moyen d'obturation étanche et de traitement contrôle également l'amplitude de l'angle d'ouverture du moyen d'obturation, de telle sorte que, dès qu'il est en fin de course de son ouverture, le moyen d'obturation soit facilement entraîné dans le sens fermeture par un doigt de la même main tenant le conteneur muni du dispositif selon l'invention.This mechanical spring means for assisting the opening and closing of the sealing and treatment means also controls the amplitude of the opening angle of the sealing means, so that, as soon as that it is at the end of its opening stroke, the closure means is easily driven in the closing direction by a finger of the same hand holding the container provided with the device according to the invention.
Le moyen mécanique à effet ressort est simultanément lié au bouchon-couvercle par une charnière-film et à la bague de fixation du dispositif selon l'invention par une autre charnière-film.The mechanical spring means is simultaneously connected to the cover cap by a film hinge and to the fixing ring of the device according to the invention by another hinge-film.
L'amplitude préférentielle de l'angle d'ouverture contrôlée par le moyen mécanique à effet ressort est d'au plus 160° et généralement compris entre 90° et 160° par distinction à l'égard de l'angle d'ouverture d'un bouchon-couvercle de l'état de la technique qui se situe autour de 180° et souvent au-delà de cette valeur.The preferred amplitude of the opening angle controlled by the mechanical spring means is at most 160 ° and generally between 90 ° and 160 ° by distinction with respect to the opening angle of a cap-lid of the state of the art which is around 180 ° and often beyond this value.
Le moyen mécanique à effet ressort a l'aspect en coupe d'une équerre qui est mise en tension. Lors de l'ouverture et de la fermeture du conteneur, le moyen mécanique en forme d'équerre subit une légère déformation au niveau des points d'attache dudit moyen mécanique, c'est à dire au niveau du bouchon-couvercle et au niveau de la bague de fixation du dispositif : la déformation angulaire du moyen mécanique en équerre est la même de chaque coté de l'équerre et est de l'ordre d'au maximum 15° de chaque coté et préférentiellement de l'ordre d'au maximum 9° de chaque coté.The mechanical spring means has the sectional appearance of a square which is tensioned. When the container is opened and closed, the square-shaped mechanical means undergoes a slight deformation at the attachment points of said mechanical means, that is to say at the level of the cap-lid and at the level of the fixing ring of the device: the angular deformation of the mechanical means at right angle is the same on each side of the square and is of the order of at most 15 ° of each side and preferably of the order of at most 9 ° on each side.
La déformation observée de l'angle formé par l'équerre entre sa position fermée et sa position ouverte est alors comprise entre 0 et au maximum 30° et préférentiellement entre 0 et au maximum 18°.The observed deformation of the angle formed by the bracket between its closed position and its open position is then between 0 and at most 30 ° and preferably between 0 and at most 18 °.
Ainsi, ce moyen d'assistance mécanique à l'ouverture ou la fermeture du moyen d'obturation de forme particulière se

Selon les
Le moyen d'obturation (1) qui est du type bouchon-couvercle comporte une paroi d'extrémité supérieure (10) constituant son plafond, munie de deux parois périphériques et tubulaires, concentriques et coaxiales dont l'une est dite paroi externe (11), l'autre paroi interne (12).According to
The closure means (1) which is of the cap-lid type has an upper end wall (10) constituting its ceiling, provided with two peripheral and tubular walls, concentric and coaxial, one of which is said outer wall (11). ), the other inner wall (12).
La paroi externe (11), périphérique et tubulaire, crée une zone de contact périphérique intime d'étanchéité, de type surface à surface, par l'établissement d'une barrière d'étanchéité entre la face interne (13) de l'enveloppe tubulaire de l'orifice d'accès et la face externe de ladite paroi externe (11).The outer wall (11), peripheral and tubular, creates an intimate peripheral sealing contact area, surface-to-surface, by establishing a sealing barrier between the inner face (13) of the envelope tubular access port and the outer face of said outer wall (11).
La forme en coupe de cette première paroi (11) révèle un renflement périphérique (14), orienté vers l'extérieur, et destiné à être au contact de la face interne (13) de l'enveloppe tubulaire de l'orifice du conteneur.The sectional shape of this first wall (11) reveals an outwardly directed peripheral bulge (14) intended to be in contact with the inner face (13) of the tubular envelope of the orifice of the container.
Quand le bouchon-couvercle (1) se place en position fermée, le renflement périphérique (14) de la première paroi (11) arrive au contact à force de la face interne (13) de l'enveloppe tubulaire de l'orifice, en subissant un certain effet de déformation et d'écrasement qui provoque une augmentation de la surface de contact du renflement périphérique (14) avec la face interne (13) de l'enveloppe tubulaire, le contact surface à surface devenant total, intime et immédiat à la fermeture par glissement et écrasement de la paroi (11) sur la paroi (13) en créant une étanchéité complète.When the cap-lid (1) is placed in closed position, the peripheral bulge (14) of the first wall (11) comes into force contact with the inner face (13) of the tubular casing of the orifice, undergoing a certain deformation and crushing effect which causes an increase in the contact area of the peripheral bulge (14) with the inner face (13) of the tubular casing, the surface-to-surface contact becoming total, intimate and immediate to closing by sliding and crushing the wall (11) on the wall (13) creating a complete seal.
La deuxième paroi, dite paroi interne (12), périphérique et préférentiellement tubulaire, constitue un logement approprié (15) pour recevoir un agent de traitement des agents polluants gazeux en particulier un agent dessicatif, la position particulière de ce logement étant déterminante pour augmenter la cinétique d'élimination desdits agents polluants gazeux.
Ce logement approprié (15), est situé sur la face interne du bouchon-couvercle, et est clos par un moyen de fermeture non étanche aux gaz pour assurer le traitement rapide de l'atmosphère gazeuse ambiante et l'élimination des agents polluants à l'égard des produits sensibles conditionnés dans le conteneur.The second wall, called the inner wall (12), which is peripheral and preferably tubular, constitutes an appropriate housing (15) for receiving a treatment agent for gaseous pollutants, in particular a desiccant, the particular position of this housing being decisive for increasing the kinetics of elimination of said gaseous pollutants.
This suitable housing (15) is located on the inner face of the cap-lid, and is closed by a non-gastight closure means to ensure the rapid treatment of the ambient gaseous atmosphere and the elimination of pollutants to the environment. sensitive products packaged in the container.
Pour faciliter la manoeuvre d'ouverture et de fermeture du bouchon-couvercle (1), le bord inférieur plan de la paroi périphérique externe peut être prolongé par une visière de préhension (17).To facilitate the operation of opening and closing the cover cap (1), the lower plane edge of the outer peripheral wall may be extended by a gripping visor (17).
Un système sécuritaire d'ouverture à l'égard des enfants, en vue de leur rendre l'ouverture du bouchon-couvercle difficile, voire impossible, peut être installé au droit de la visière (17). Ce dispositif est une lame souple (23) faisant partie intégrante du moyen de montage et se présentant sous la forme d'une excroissance établissant un vide entre elle et le moyen de montage. Cette lame souple est placée en dessous de la visière en en suivant le profil de telle manière que le dépassement de la visière permettant d'exercer une poussée verticale pour en assumer son ouverture soit carénée par cette lame souple en l'absence de sollicitation. Dès lors l'accès à la visière ne peut se faire qu'après avoir exercé une pression sur cette lame en vue d'en provoquer la déformation et libérer l'accès à ladite visière. Par un tel moyen, la protection de l'enfant est assuré par la nécessaire réalisation de deux gestes complémentaires, et à exercer simultanément, le premier geste étant une pression horizontale sur la lame souple, le deuxième étant une action de poussée verticale de bas en haut sur la visière dégagée, grâce au maintien de la pression sur la lame souple.A safe opening system for children, in order to make it difficult or impossible for them to open the lid-cap, can be installed in line with the visor (17). This device is a flexible blade (23) forming an integral part of the mounting means and is in the form of a protrusion establishing a vacuum between it and the mounting means. This flexible blade is placed below the visor by following the profile so that the protrusion of the visor for exerting a vertical thrust to assume its opening is careened by the flexible blade in the absence of stress. Therefore access to the visor can be done only after exerting pressure on the blade to cause deformation and release access to said visor. By such a means, the protection of the child is ensured by the necessary two complementary gestures to be performed, and to exercise simultaneously, the first gesture being a horizontal pressure on the flexible blade, the second being a vertical pushing action from below to high on the unobstructed visor, thanks to the maintenance of the pressure on the flexible blade.
Le moyen de montage (2) du bouchon-couvercle (1) est formé d'une bague de fixation (2) qui est montée sur l'enveloppe tubulaire de l'orifice d'accès au conteneur à obturer, cette bague :
- ayant un dimensionnement adapté à celui de l'enveloppe tubulaire,
- étant munie sur sa face interne, destinée à être au contact de la surface externe de l'enveloppe d'un moyen d'encliquetage en relief (18), à l'égard de la face externe de l'enveloppe, sur laquelle le moyen permettant l'encliquetage de la bague est à l'opposé, c'est-à-dire en creux. Selon une variante de l'invention représentée sur la
figure 11 , la surface périphérique externe de l'enveloppe tubulaire (24) de l'orifice (4) d'accès au conteneur à obturer comporte deux collerettes périphériques en saillie (26) et (27), séparées l'une de l'autre en créant une gorge (25), présentant en coupe une forme sensiblement rectangulaire, de telle sorte que :- l'épaisseur de l'enveloppe tubulaire à l'intérieur de la gorge n'est pas modifiée, et que
- la bague de fixation (2) vient se monter à force dans ladite gorge (25).
- having a dimensioning adapted to that of the tubular envelope,
- being provided on its inner face, intended to be in contact with the outer surface of the envelope of a relief snap-fastening means (18), with respect to the outer face of the envelope, on which the means allowing the snap of the ring is the opposite, that is to say hollow. According to a variant of the invention shown on the
figure 11 , the outer peripheral surface of the tubular casing (24) of the orifice (4) for access to the container to be closed comprises two projecting peripheral flanges (26) and (27), separated from one another by creating a groove (25) having a substantially rectangular shape in section such that:- the thickness of the tubular casing inside the groove is not changed, and that
- the fixing ring (2) is forced into said groove (25).
Selon une autre variante de l'invention représentée sur la
- l'épaisseur de l'enveloppe tubulaire à l'intérieur de la gorge est modifiée, et est inférieure à celle de l'enveloppe tubulaire et que
- la bague de fixation (2) vient se monter à force dans ladite gorge (25) .
- the thickness of the tubular casing inside the groove is modified, and is less than that of the tubular casing and that
- the fixing ring (2) is forced into said groove (25).
Le moyen de liaison (3) de type charnière relativement rigide, est présent entre le moyen d'obturation (1) et le moyen de montage (2) sur l'enveloppe tubulaire de l'orifice d'accès au conteneur (4).The relatively rigid hinge type connecting means (3) is present between the closure means (1) and the mounting means (2) on the tubular casing of the container access port (4).
Ce moyen de liaison (3) de type charnière, selon l'invention, est formée de deux charnières-films (6) et (7) espacées l'une de l'autre, et donnant de la rigidité à la liaison entre le bouchon-couvercle (1) et la bague de fixation (2).This connecting means (3) of the hinge type, according to the invention, is formed of two hinges-films (6) and (7) spaced apart from each other, and giving rigidity to the connection between the plug -cover (1) and the fixing ring (2).
Chaque charnière-film (6) et (7) est formée de deux parties reliées entre elles par un film polymère jouant le rôle d'un axe de rotation (19) et (20) permettant les cycles d'ouverture/fermeture du moyen d'obturation, l'une des parties étant intégrée au moyen d'obturation (1), l'autre partie étant intégrée au moyen de montage (2).Each film hinge (6) and (7) is formed of two parts interconnected by a polymer film acting as an axis of rotation (19) and (20) allowing the cycles opening / closing of the closure means, one of the parts being integrated in the closure means (1), the other part being integrated in the mounting means (2).
Les deux parties de chacune des deux charnières (6) et (7) intégrées au moyen d'obturation (1) et au moyen de montage (2) constituent des potences de fixation des deux charnières-film sur le moyen d'obturation et le moyen de montage.The two parts of each of the two hinges (6) and (7) integrated in the closure means (1) and the mounting means (2) constitute brackets for fixing the two hinges-film on the closure means and the mounting medium.
Ces deux types de charnière-film (6) et (7) assurent le meilleur fonctionnement à la fermeture (de même qu'à l'ouverture) de la mise en place du bouchon-couvercle (1) sur l'orifice (4) de l'enveloppe à obturer par l'usage d'un seul doigt de la main tenant le conteneur, grâce à un guidage mécanique parfait dudit bouchon-couvercle, ne nécessitant, pour achever la fermeture, qu'une pression verticale du haut vers le bas, qui provoque l'encliquetage du bouchon-couvercle.These two types of film hinge (6) and (7) ensure the best operation at closing (as well as opening) of the installation of the cap-lid (1) on the orifice (4) the envelope to be sealed by the use of a single finger of the hand holding the container, thanks to a perfect mechanical guidance of said cap-lid, requiring, to complete the closure, only a vertical pressure from the top to the bottom, which causes the snap of the cap-lid.
Le moyen d'inviolabilité (8) ou encore témoin d'inviolabilité, est formée de micro-liens reliant la surface périphérique inférieure du bouchon-couvercle (1) à la surface périphérique supérieure de la bague de fixation (2), ces micro-liens étant des micro-points de liaison, indépendants les uns des autres, formant une couronne dentée périphérique de liaison entre le moyen d'obturation dessicatif et le moyen de montage sur l'enveloppe tubulaire de l'orifice du conteneur, couronne qui est rompue lors de la première ouverture par soulèvement du bouchon-couvercle au moyen de la visière (17).The tamper-proof means (8) or tamper-proof means is formed of micro-links connecting the lower peripheral surface of the cap-lid (1) to the upper peripheral surface of the fixing ring (2), these micro-wires links being micro-points of connection, independent of each other, forming a peripheral ring gear connecting the desiccant sealing means and the mounting means on the tubular casing of the orifice of the container, which ring is broken during the first opening by lifting the cap-lid by means of the visor (17).
Le moyen mécanique à effet ressort (9) pour l'assistance à l'ouverture ou la fermeture du moyen d'obturation dessicatif (1), est placé dans l'espace situé entre les deux charnières-films (6) et (7) et a l'aspect en coupe d'une équerre.The mechanical spring means (9) for assisting the opening or closing of the desiccant sealing means (1) is placed in the space between the two film hinges (6) and (7) and has the sectional appearance of a square.
Ce moyen mécanique (9) à effet ressort contrôle également l'amplitude de l'angle d'ouverture du moyen d'obturation (1) qui est dans le cas présent à 120°, de telle sorte que, à partir de sa position de fin de course à 120°, le moyen d'obturation est facilement entraîné dans le sens de la fermeture par un doigt de la main tenant le conteneur muni du dispositif d'obturation.This spring-acting mechanical means (9) also controls the amplitude of the opening angle of the closure means (1), which is in this case at 120 °, so that, from its position of end of stroke at 120 °, the closure means is easily driven in the direction of closure by a finger of the hand holding the container provided with the closure device.
Le moyen mécanique à effet ressort (9) est simultanément lié au bouchon-couvercle (1) par une charnière-film (21) et à la bague de fixation (2) du dispositif selon l'invention par une autre charnière-film(22).The mechanical spring means (9) is simultaneously connected to the cover cap (1) by a film hinge (21) and to the fixing ring (2) of the device according to the invention by another hinge-film (22). ).
