BOUCHON INVIOLABLE DE SECURITE POUR BOUTEILLES DE GAZINVIOLABLE SAFETY CAP FOR GAS BOTTLES
DE 12 ET 34 KG FROM 12 TO 34 KG
Description Description
Domaine de l’invention Field of the invention
La présente invention concerne le domaine technique des dispositifs de fermeture pour un robinet de bouteille à gaz pour gaz liquéfiés, dissous ou comprimés. Plus précisément, elle concerne une capsule inviolables et témoins de d’obsturation pour fermeture . The present invention relates to the technical field of closing devices for a gas cylinder valve for liquefied, dissolved or compressed gases. More specifically, it concerns a tamper-evident capsule and blockage witnesses for closure.
Etat de l’art State of the art
Les bouteilles de gaz sont remplies de gaz et sont laissés pendant de longues périodes en stockage ou à l'air libre, et elles sont généralement équipées, pour la sortie du gaz, d'un robinet par lequel le gaz est évacué lors de l'ouverture de la bouteille, ou d'une valve par laquelle le gaz est évacué lors du branchement d'un détendeur. D’où il convient d'utiliser des capsules, qui sont normalement constitués par des capuchons en plastique, à appliquer de manière détachable sur la deuxième extrémité de sortie du corps de vanne afin d'éviter, d'une part, la poussière ou la saleté de pénétrer dans le corps de la vanne et en même temps d’assurer une étanchéité afin de freiner l'écoulement de gaz de la vanne avant utilisation . Gas cylinders are filled with gas and are left for long periods in storage or in the open air, and they are usually equipped, for the gas outlet, with a valve through which the gas is discharged during the discharge. opening of the bottle, or of a valve through which the gas is evacuated when connecting a regulator. Hence it is advisable to use capsules, which are normally constituted by plastic caps, to be applied in a detachable manner on the second outlet end of the valve body in order to avoid, on the one hand, dust or dirt. dirt from entering the valve body and at the same time providing a seal to restrict the flow of gas from the valve before use.
Les distributeurs disposent généralement une capsule sur la valve, après remplissage de la bouteille, afin d'éviter, d'une part, la poussière ou la saleté de pénétrer dans le corps de la vanne et en même temps permettant de garantir leur inviolabilité et de ce fait, leur première ouverture par les consommateurs. Dispensers generally have a cap on the valve, after filling the bottle, in order to prevent, on the one hand, dust or dirt from entering the valve body and at the same time making it possible to guarantee their inviolability and this fact, their first opening by consumers.
Les bouchons existants sont tels qu'ils peuvent être à volonté retirés de l'embout puis replacés sur celui-ci. Ils n'offrent donc aucune garantie particulière quant à l'inviolabilité de la bouteille avant sa première ouverture et l'utilisateur, ou le détaillant installateur, n'a aucune certitude, à l'ouverture de la bouteille, que celle-ci n'a pas déjà été ouverte. The existing caps are such that they can be removed at will from the nozzle and then replaced on it. They therefore offer no particular guarantee as to the inviolability of the bottle before its first opening and the user, or the installer retailer, has no certainty, when opening the bottle, that it is not has not already been opened.
Différent types de capsules de sécurité sont déjà divulguées. Le document FR2659420 décrit par exemple une capsule inviolable venant coiffer le raccord externe, comprenant plusieurs crans (4) s'engageant dans le filetage ou le taraudage
du raccord externe (21 ), ce ou ces crans ne pouvant être dégagés qu’en brisant la capsule suivant des amorces de rupture (5) situées sur sa paroi latérale (6), grâce à un anneau de traction (3) solidaire de ladite capsule, d’autre part, deux oreilles latérales (2) situées dans le prolongement de ladite paroi latérale, s'appuyant sur le carré de vissage (22) du robinet (20) pour empêcher la capsule (1) d'être retirée par dévissage et dont la position excentrée n'autorise qu'une seule possibilité de mise en place et, d'autre part, un anneau d'extraction (3). La capsule est munie de deux oreilles latérales n'autorisant qu'une seule possibilité de mise en place. Different types of security capsules are already disclosed. Document FR2659420 describes, for example, a tamper-proof cap covering the external connector, comprising several notches (4) engaging in the thread or the internal thread. of the external connection (21), this or these notches being able to be released only by breaking the capsule following rupture initiators (5) located on its side wall (6), thanks to a traction ring (3) integral with said capsule, on the other hand, two side ears (2) located in the extension of said side wall, resting on the screwing square (22) of the valve (20) to prevent the capsule (1) from being withdrawn by unscrewing and whose eccentric position allows only one possibility of installation and, on the other hand, an extraction ring (3). The capsule is provided with two lateral ears allowing only one possibility of installation.
L’inconvénient de cette capsule, d’une part c’est qu’il n’assure qu’un seul niveau d’étanchéité au niveau du filetage de la capsule et du taraudage du robinet et vue la façon par laquelle les capsules sont montées (enfoncées) il se trouve que le filetage abîmé de Sa capsule n’assure plus une étanchéité efficace. Un autre inconvénient de cette capsule c’est qu’il est utilisable qu’une seule fois et il sera impossible de le réutiliser en cas de détection d’une anomalie par le consommateur. The disadvantage of this capsule, on the one hand, is that it only provides a single level of tightness at the level of the thread of the capsule and the thread of the tap and for the way in which the capsules are mounted. (pressed) it turns out that the damaged thread of its capsule no longer provides an effective seal. Another disadvantage of this capsule is that it can be used only once and it will not be possible to reuse it if an anomaly is detected by the consumer.
Un autre document de brevet n° FR 2647185 décrit une capsule de sécurité comprenant un capuchon venant recouvrir le volant supérieur et une languette recouvrant l'orifice de sortie du gaz. La languette est simplement appliquée sur l'orifice de sortie sans accroche spécifique autre que sa liaison au capuchon supérieur. Ces capsules n'offrent donc pas une entière satisfaction que ce soit vis-à- vis de la garantie d'inviolabilité ou de la mise en place sur la valve. il est possible de mentionner qu’il existe des documents de l’état de la technique divulguant des indicateurs d'ouverture sous forme de jonctions détachables qui se trouvent reliées à la base et au couvercle et sont pourvues d' une zone de rupture qui se fragmente, se détache ou change de position après la première ouverture du couvercle. Ces indicateurs ont pour but de fournir une preuve visible et équivoque du fait que le récipient a été ouvert avant son acquisition par le consommateur. il est possible de mentionner aussi le document référencé ES2084159, dans lequel est définie une fermeture indicatrice de manipulation pour un emballage, qui comprend une bague annulaire de fermeture qui présente un couvercle de fermeture et une bande de scellement annulaire reliée de manière détachable au couvercle par des moyens frangibles. Elle comprend en outre une pluralité de saillies souples sur la bande, s'étendant circonférentiellement vers l’intérieur et des moyens d'interférence
associés à celles-ci qui coopèrent avec elles pour fracturer les moyens frangibles pendant le retrait de la fermeture de l’emballage. Another patent document No. FR 2647185 describes a safety capsule comprising a cap covering the upper flywheel and a tab covering the gas outlet orifice. The tab is simply applied to the outlet port without any specific grip other than its connection to the top cap. These capsules therefore do not offer complete satisfaction, whether with regard to the guarantee of inviolability or the installation on the valve. it is possible to mention that there are documents of the state of the art disclosing opening indicators in the form of detachable joints which are found connected to the base and to the cover and are provided with a rupture zone which intersects. fragments, becomes detached or changes position after the first opening of the cover. These indicators are intended to provide visible and equivocal proof that the container was opened before its acquisition by the consumer. it is also possible to mention the document referenced ES2084159, in which is defined a closure indicating handling for a package, which comprises an annular closure ring which has a closure cover and an annular sealing strip detachably connected to the cover by frangible means. It further comprises a plurality of flexible projections on the strip, extending circumferentially inwardly and interference means. associated with these which cooperate with them to fracture the frangible means during the removal of the closure of the packaging.
Le document FR2647184 décrit une capsule de sécurité destinée à garantir l'inviolabilité d'une bouteille de gaz équipée d'un robinet (2) comportant, pour ta sortie du gaz, un orifice (6) qui débouche dans un embout (7) vers son extrémité par Laquelle le gaz est évacué du robinet, des moyens (6a, 7a) de raccordement avec un conduit de distribution du gaz étant ménagé sur ledit embout, La capsule étant caractérisée en ce qu'elle comprend un corps (9, 9') cylindrique à section circulaire qui présente, sur sa paroi de cylindre, ces crans (20, 20') de verrouillage destinés à venir coopérer avec Lesdits moyens (6a, 7a) de raccordement et qui est fermé à une première extrémité de cylindre par une paroi de fond (10, 10') propre à venir obturer L'orifice (6) du robinet, ledit corps comportant deux régions (14, 15 ; 14', 15') de moindre résistance séparées L’une de l'autre par une bande (16) de matière, lesdites régions s'étendant sensiblement parallèlement Le long- de La paroi cylindrique du corps (9, 9') et se prolongeant le Long te sa paroi de fond (10, 10'), la bande qui Les sépare étant reliée à une languette (17) d'arrachement propre à permettre le déchirement de La capsule Le Long de ses régions de moindre résistance. Document FR2647184 describes a safety cap intended to guarantee the inviolability of a gas cylinder equipped with a valve (2) comprising, for your gas outlet, an orifice (6) which opens into a nozzle (7) towards its end through which the gas is discharged from the valve, means (6a, 7a) for connection with a gas distribution duct being provided on said nozzle, The capsule being characterized in that it comprises a body (9, 9 ' ) cylindrical with a circular section which has, on its cylinder wall, these locking notches (20, 20 ') intended to cooperate with said connecting means (6a, 7a) and which is closed at a first end of the cylinder by a bottom wall (10, 10 ') suitable for closing off the orifice (6) of the valve, said body comprising two regions (14, 15; 14', 15 ') of lower resistance separated from each other by a strip (16) of material, said regions extending substantially parallel along the cylindrical wall of the body. rps (9, 9 ') and extending along its bottom wall (10, 10'), the band which separates them being connected to a tear-off tab (17) suitable for allowing the tearing of the Le Long capsule of its regions of least resistance.
Les inconvénients de cette solution sont : The disadvantages of this solution are:
- il assure un seul niveau d’étanchéité au niveau de filetage du robinet et le taraudage de la capsule. - it provides a single level of tightness at the level of the tap thread and the thread of the capsule.
- Le seul moyen de montage des capsules c’est par enfoncement et ça ne peut être en aucun cas par filetage si non le montage par filetage engendra le déchirement des indicateurs d’inviolabilité (19) - The only means of mounting the capsules is by driving in and it can not be by threading if not the mounting by threading causes the tearing of the tamper-evident indicators (19)
- les capsules sont montées par enfoncement qui abîme le seul niveau qui assure l’étanchéité entre le robinet et la capsule. - the capsules are mounted by indentation which damages the only level that ensures the seal between the valve and the capsule.
