Description

Dispositif de stockage de fluide et procédé de montage d'un chapeau sur un tel dispositif  Fluid storage device and method of mounting a cap on such a device
La présente invention concerne un dispositif de stockage de fluide et un procédé de montage d'un chapeau sur un tel dispositif. The present invention relates to a fluid storage device and a method of mounting a cap on such a device.
L'invention concerne plus particulièrement un dispositif de stockage de fluide comprenant un récipient, notamment une bouteille de gaz sous pression, comportant un robinet monté dans un orifice du récipient et un chapeau de protection monté sur le récipient, le dispositif comportant une bague de montage distincte du chapeau interposée entre le récipient et le chapeau, la bague de montage étant fendue, c'est-à-dire présentant une ouverture unique sur sa circonférence prévue pour sa mise en place ou son retrait relativement au récipient, l'ouverture de la bague étant prévue pour former, lors d'une mise en place ou d'un retrait de la bague, un passage pour une portion ou une section du récipient ou d'un organe monté sur le récipient tel que le robinet, le chapeau comprend, en position démontée, au moins deux parties mobiles l'une par rapport à l'autre, en position montée lesdites parties du chapeau étant solidarisées et enserrant la bague sur le récipient.  The invention more particularly relates to a fluid storage device comprising a container, in particular a pressurized gas bottle, comprising a valve mounted in a port of the container and a protective cap mounted on the container, the device comprising a mounting ring. distinct from the cap interposed between the container and the cap, the mounting ring being slotted, that is to say having a single opening on its circumference provided for its introduction or withdrawal relative to the container, the opening of the ring being provided to form, during an introduction or withdrawal of the ring, a passage for a portion or a section of the container or a member mounted on the container such as the tap, the cap comprises, in the disassembled position, at least two parts movable relative to each other, in the mounted position, said parts of the cap being secured and enclosing the ring on the container.
Un exemple d'un tel dispositif est décrit dans le document FR2900717A1 . An example of such a device is described in document FR2900717A1.
Cette architecture permet de monter/démonter un chapeau de protection d'un robinet sans nécessiter le démontage du robinet. This architecture makes it possible to assemble / disassemble a protective cap of a faucet without requiring disassembly of the faucet.
La bague fendue de montage du chapeau de protection d'un tel dispositif a vocation à être réalisée en métal car l'obtention d'une bague fendue en plastique présente des difficultés.  The split ring mounting the protective cap of such a device is intended to be made of metal because obtaining a split plastic ring presents difficulties.
En effet, dans le cas d'une bague en matière plastique injectée, les inventeurs ont constaté que le caractère fendu génère une déformation importante de la bague lors de son refroidissement.  Indeed, in the case of an injected plastic ring, the inventors have found that the split character generates a significant deformation of the ring during its cooling.
Une diminution de la largeur de la fente de la bague peut ainsi rendre difficile ou impossible le montage de la bague autour d'un robinet ou autour du récipient.  A decrease in the width of the slot of the ring can thus make it difficult or impossible to mount the ring around a valve or around the container.
De même, dans le cas d'une bague taraudée, des déformations dues à la fabrication peuvent empêcher un bon vissage ou un vissage aisé de la bague sur le filetage du récipient. Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. Similarly, in the case of a threaded ring, deformations due to manufacture can prevent good screwing or easy screwing of the ring on the thread of the container. An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
A cette fin, le dispositif selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que la bague de montage est constituée de matériau plastique moulé ou injectée et ce que l'ouverture de la bague de montage est obtenue par le retrait d'une portion sécable de la bague moulée ou injectée en même temps que le reste de la bague.  To this end, the device according to the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that the mounting ring is made of molded or injected plastic material and that the Opening of the mounting ring is obtained by removing a breakable portion of the ring molded or injected at the same time as the rest of the ring.
Par ailleurs, des modes de réalisation de l'invention peuvent comporter l'une ou plusieurs des caractéristiques suivantes :  Furthermore, embodiments of the invention may include one or more of the following features:

- le retrait de la portion sécable de la bague est réalisé manuellement.  - The removal of the breakable portion of the ring is made manually.
L'invention peut concerner également tout dispositif ou procédé alternatif comprenant toute combinaison des caractéristiques ci-dessus ou ci-dessous.  The invention may also relate to any alternative device or method comprising any combination of the above or below features.
D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence aux figures dans lesquelles :  Other particularities and advantages will appear on reading the following description, made with reference to the figures in which:
- la figure 1 représente une vue en perspective, schématique et partielle, illustrant un exemple de dispositif de stockage de fluide selon l'invention,  FIG. 1 represents a schematic and partial perspective view illustrating an example of a fluid storage device according to the invention,
- la figure 2 représente une vue en perspective agrandie, d'un détail de la figure 1 illustrant un exemple de réalisation de la bague de montage.  - Figure 2 shows an enlarged perspective view of a detail of Figure 1 illustrating an embodiment of the mounting ring.
Le dispositif de stockage de fluide illustré à titre d'exemple non limitatif à la figure 1 comprend un récipient 1 , par exemple une bouteille de gaz sous pression.  The fluid storage device illustrated by way of non-limiting example in Figure 1 comprises a container 1, for example a pressurized gas bottle.
Un robinet 2 est monté (par exemple vissé) dans un orifice du récipient 1 . A valve 2 is mounted (for example screwed) into an orifice of the container 1.
Un chapeau 3 de protection en deux ou plus parties est destiné à être monté sur le récipient 1 , autour du robinet 2. A protective cap 3 in two or more parts is intended to be mounted on the container 1, around the valve 2.
Une bague 4 de montage distincte (séparée physiquement) du chapeau 3 est interposée à cet effet entre le récipient 1 et le chapeau 3. La bague 4 de montage est fendue, c'est-à-dire présente une ouverture 14 unique sur sa circonférence prévue pour sa mise en place ou son retrait relativement au récipient 1 . L'ouverture 14 de la bague 4 est en effet prévue pour former, lors d'une mise en place ou d'un retrait de la bague 4, un passage pour une portion ou une section du récipient ou d'un organe monté sur le récipient tel que le robinet 2. Le chapeau 3 comprend, en position démontée, au moins deux parties mobiles l'une par rapport à l'autre et, en position montée lesdites parties du chapeau 3 sont solidarisées (vissage et/ou encliquetage) et enserrent la bague 4 sur le récipient 1 . A separate mounting ring 4 (physically separated) from the cap 3 is interposed for this purpose between the container 1 and the cap 3. The mounting ring 4 is split, that is to say has a single opening 14 on its circumference provided for its introduction or withdrawal relative to the container 1. The opening 14 of the ring 4 is in fact intended to form, during an introduction or withdrawal of the ring 4, a passage for a portion or a section of the container or a member mounted on the The cap 3 comprises, in the disassembled position, at least two parts that are movable relative to each other and, in the mounted position, said parts of the cap 3 are secured (screwing and / or latching) and enclose the ring 4 on the container 1.
La bague 4 a par exemple la forme générale d'un anneau cylindrique.  The ring 4 has for example the general shape of a cylindrical ring.
Selon une particularité avantageuse, la bague 4 de montage est constituée de matériau plastique moulé ou injectée ou obtenu par tout autre technique appropriée et l'ouverture de la bague 4 de montage est obtenue par le retrait d'une portion 24 sécable de la bague 4 moulée ou injectée en même temps que le reste de la bague 4.  According to an advantageous feature, the mounting ring 4 is made of molded or injected plastic material or obtained by any other appropriate technique and the opening of the mounting ring 4 is obtained by removing a breakable portion 24 of the ring 4 molded or injected at the same time as the rest of the ring 4.
De préférence, la bague 4 de montage est moulée ou injectée non fendue avec au moins une zone 34 fragilisée délimitant la portion 24 sécable, pour faciliter le retrait de la portion 24 sécable (figure 2).  Preferably, the mounting ring 4 is molded or injected unslotted with at least one weakened zone 34 delimiting the portion 24 breakable, to facilitate removal of the portion 24 breakable (Figure 2).
La zone 34 fragilisée peut comprendre par exemple au moins l'un parmi : une diminution relative d'épaisseur localisée, au moins une fente, au moins une pluralité de trous contigus.  The weakened zone 34 may comprise, for example, at least one of: a relative decrease in localized thickness, at least one slot, at least a plurality of contiguous holes.
De plus, comme visible à la figure 2, la portion 24 sécable peut comprendre une zone 44 de préhension faisant saillie au-delà du corps de la bague 4 pour faciliter son retrait manuel.  In addition, as shown in Figure 2, the portion 24 breakable may include a gripping area 44 projecting beyond the body of the ring 4 to facilitate its manual removal.
Comme illustré à la figure 2, la zone 44 de préhension peut comporter deux languettes parallèles faisant saillie radialement par rapport au reste de la bague 4. Bien entendu, toute autre géométrie de zone de préhension peut être envisagée : anneau(x), languette(s)...  As illustrated in FIG. 2, the zone 44 for gripping may comprise two parallel tongues protruding radially from the remainder of the ring 4. Of course, any other geometry of the gripping zone may be envisaged: ring (x), tongue ( s) ...
Comme visible à la figure 2, la bague 4 possède une surface intérieure 104 destinée à être montée sur la surface extérieure du récipient 1 et une surface extérieure 204 destinée à coopérer avec une surface du chapeau 3 pour le montage de ce dernier sur le récipient 1 . La surface intérieure 104 de la bague 4 peut comporter des reliefs d'accrochage (taraudage par exemple) pour coopérer avec une surface conjuguée (filetée) au niveau d'un col du récipient 1 . As can be seen in FIG. 2, the ring 4 has an inner surface 104 intended to be mounted on the outer surface of the container 1 and an outer surface 204 intended to cooperate with a surface of the cap 3 for mounting the latter on the container 1 . The inner surface 104 of the ring 4 may comprise hooking reliefs (tapping for example) to cooperate with a conjugate surface (threaded) at a neck of the container 1.
La surface extérieure 104 de la bague 4 peut comporter un profil d'accrochage ou de positionnement destiné à coopérer sélectivement avec un profil complémentaire d'une surface du chapeau 3.  The outer surface 104 of the ring 4 may comprise a hooking or positioning profile intended to selectively cooperate with a complementary profile of a surface of the cap 3.
L'invention permet ainsi de rendre possible l'utilisation d'une bague 4 de montage en plastique sans les inconvénients de l'art antérieur.  The invention thus makes it possible to use a plastic mounting ring 4 without the disadvantages of the prior art.
La fabrication de la bague 4 complète (non fendue) et le retrait ultérieur de la portion 24 formant la fente évite ou diminue fortement les déformations intempestives.  The manufacture of the complete ring 4 (not split) and the subsequent withdrawal of the portion 24 forming the slot greatly avoids or reduces the unwanted deformations.
La mise en place de la bague 4 est facilitée et la bague 4 conserve une flexibilité permettant sa mise en place.  The establishment of the ring 4 is facilitated and the ring 4 retains flexibility for its implementation.
L'invention permet ainsi l'utilisation d'une bague 4 de montage en plastique injecté ou moulé plus légère et moins coûteuse qu'une pièce métallique.  The invention thus allows the use of a mounting ring 4 injected plastic or molded lighter and less expensive than a metal part.
Le caractère sécable de la portion 24 permet une grande facilité d'utilisation et de montage. De plus, en cas de choc important subi par le dispositif, la bague 4 fendue en plastique peut former un fusible mécanique qui se rompt avant de détériorer le filetage du récipient 1 .  The breakable character of the portion 24 allows great ease of use and assembly. In addition, in the event of a major shock to the device, the plastic split ring 4 may form a mechanical fuse which breaks before deteriorating the thread of the container 1.
