Description

BOUTEILLE DE GAZ SOUS PRESSION BOTTLE OF GAS UNDER PRESSURE
L'invention concerne une bouteille pour gaz sous pression comprenant un réservoir, notamment métallique contenu dans une enveloppe de protection extérieure comportant au moins une embase formant le piètement de la bouteille et une partie formant couvercle .The invention relates to a bottle for pressurized gas comprising a reservoir, in particular a metal reservoir contained in an outer protective casing, comprising at least one base forming the base of the bottle and a portion forming a lid.
La présente invention trouvera son application dans le domaine de la conception de réservoirs tout particulièrement métalliques et d'une nature transportable tel que des bouteilles à gaz liquéfié.The present invention will find application in the field of the design of particularly metal tanks and of a transportable nature such as liquefied gas cylinders.
Si, par le passé, de tels réservoirs comportaient, usuellement, une enveloppe métallique à la base de laquelle était simplement soudé un anneau formant piètement tandis que sur sa partie supérieure était vissé un embout protecteur du robinet détendeur, embout intégrant une poignée de transport, il est de plus en plus fréquent de concevoir ces bouteilles de gaz sous forme d'un réservoir métallique que l'on vient intégralement habiller d' une enveloppe de protection extérieure comportant une embase formant piètement de la bouteille tandis qu'en partie supérieure, cette enveloppe intègre, généralement, des poignées de transport.If, in the past, such tanks usually had a metal casing at the base of which was simply welded a ring forming a base while on its upper part was screwed a protective cap of the valve regulator, the endpiece incorporating a carrying handle, it is more and more common to design these gas cylinders in the form of a metal tank which is fully covered with an outer protective envelope comprising a base forming the base of the bottle while the upper part, this Envelope integrates, usually, carrying handles.
Cette méthode de fabrication actuelle des bouteilles destinées à contenir du gaz sous pression permet d' améliorer leur aspect esthétique .This present method of manufacturing bottles intended to contain gas under pressure makes it possible to improve their aesthetic appearance.
En l'occurrence, si le réservoir proprement dit était, jusqu'alors, réalisé en tôle épaisse pour absorber les différents chocs que peuvent subir de telles bouteilles de gaz, que ce soit lors de leur transport ou au cours des cycles de remplissage successifs , cette protection est maintenant assurée par l'enveloppe externe, préférentiellement, en matériau synthétique, le réservoir proprement dit comportant à présent une paroi mince en acier à haute limite élastique .In this case, if the tank itself was, until then, made of thick sheet to absorb the various shocks that can suffer such gas cylinders, either during transport or during successive filling cycles, this protection is now provided by the outer shell, preferably made of synthetic material, the actual tank now having a thin wall made of steel with a high elastic limit.
Précisément, il existe, actuellement, différentes méthodes de conception de ces bouteilles de gaz à enveloppe de protection externe . En particulier, on connaît par le document FR-2.707.369, une bouteille de gaz dont l'enveloppe de protection extérieure se compose au moins de deux parties mobiles entre elles et susceptibles d'être rendues solidaires l'une de l'autre par l'intermédiaire de moyens de liaison escamotables.Specifically, there are, at present, different methods of designing these gas cylinders external protective envelope. In particular, document FR-27097369 discloses a gas cylinder whose outer protection envelope is composed of at least two mutually movable parts which can be made integral with one another by via retractable connecting means.
Comme il était déjà connu auparavant des réservoirs destinés à contenir un gaz ou liquide sous pression, réservoir pourvu d'une enveloppe de protection externe non escamotable car conçue par surmoulage ou par assemblage par collage ou soudure des éléments de cette enveloppe, il a été souligné dans le document FR-2.707.369 que dans le cas particulier de bouteilles destinées à contenir un gaz sous pression, il était souhaitable de pouvoir inspecter de manière périodique le réservoir métallique pour s'assurer de son étanchéité. Dans une solution de type surmoulage, cela imposait la destruction totale de cette enveloppe de protection extérieure .As was previously known reservoirs for containing a gas or liquid under pressure, a tank provided with an outer shell non-retractable as designed by overmolding or assembly by gluing or welding the elements of this envelope, it has been underlined in the document FR-27097369 that in the particular case of bottles intended to contain a gas under pressure, it was desirable to be able to periodically inspect the metal container to ensure its tightness. In an overmoulding solution, this required the total destruction of this outer protection envelope.
C'est donc la raison pour laquelle il est prévu, dans le document n° 2.707.369 que cette enveloppe soit constituée d'au moins deux parties démontables pour autoriser le retrait du réservoir et donc son inspection.This is why it is provided in document No. 2,707,369 that this envelope consists of at least two removable parts to allow the removal of the tank and therefore its inspection.
Ce document de l'état de la technique donne différentes solutions de liaison escamotables plus particulièrement, certains modes de réalisations prévoient des moyens de liaison sous forme d' organes de retenue encliquetables définis par une partie mâle et une partie femelle de type tenon mortaise ou de crochet de retenue de forme conjuguée dont sont pourvues, à hauteur de leur jonction, les bords libres des deux parties de cette enveloppe .This document of the state of the art gives different retractable connection solutions more particularly, some embodiments provide connecting means in the form of snap retainers defined by a male part and a female part mortise type or hook of conjugate form of which are provided, at their junction, the free edges of the two parts of this envelope.
Même s'il était prévu, dans ce cas, de retirer, en force, les deux parties l'une de l'autre, ce retrait restait dans tous les cas possible quel que soit le mode de réalisation.Even if it was intended, in this case, to withdraw, in force, the two parts from each other, this withdrawal remained in all cases possible regardless of the embodiment.
Cela suppose qu'un démontage, même s'il est rendu difficile est normalement accessible qu'à des personnes habilitées, reste possible à qui cherche absolument à accéder au réservoir métallique que contient l'enveloppe de protection. Or, justement, cet accès doit être rendu impossible à l'usager, ou tout du moins si l'usager a accédé à ce réservoir métallique , cela doit être rendu visible au moment du cycle suivant de remplissage de la bouteille de gaz . Dans un autre aspect, il est prévu dans le document EP 0 958 473 une bouteille de gaz comportant un réservoir réalisé en matériau transparent et une enveloppe extérieure composée d'une partie haute formant couvercle, d'une partie basse formant les pieds et d'une partie centrale constituant le corps de la bouteille. Plus particulièrement, la partie centrale de cette bouteille comporte des sections extrudées laissant apparaître le réservoir transparent et la quantité restante de gaz de la bouteille.This supposes that disassembly, even if it is made difficult, is normally accessible only to authorized persons, it is possible for anyone who absolutely seeks access to the metal tank contained in the protective envelope. However, precisely, this access must be made impossible to the user, or at least if the user has access to this metal tank, it must be made visible at the next cycle of filling the gas cylinder. In another aspect, document EP 0 958 473 provides for a gas bottle comprising a reservoir made of transparent material and an outer envelope composed of a top part forming a lid, a lower part forming the feet and a central part constituting the body of the bottle. More particularly, the central portion of this bottle has extruded sections revealing the transparent reservoir and the remaining amount of gas from the bottle.
On comprend bien que dans ce cas , l' accès au réservoir est possible pour l'utilisateur au travers sections extrudés. Ce qui d'une part entraîne un risque de dégradation du réservoir et des problèmes de sécurité vis-à-vis de l'utilisateur. De plus, les différentes parties constituant l'enveloppe extérieure sont assemblées entre-elles par des moyens de liaisons escamotables de manière à permettre un démontage du réservoir par 1' utilisateur .It is understood that in this case, access to the tank is possible for the user through extruded sections. Which on the one hand leads to a risk of degradation of the reservoir and safety problems vis-à-vis the user. In addition, the different parts constituting the outer casing are assembled together by means of retractable connections so as to allow disassembly of the reservoir by the user.
On a également pu constater qu'au cours de leur cycle de vie, de telles bouteilles pour gaz sous pression sont amenées à subir de multiples manipulation au cours desquelles ces bouteilles sont soit entrechoquées les unes par rapport aux autres, notamment en phase de remplissage et de transport, tout comme ces bouteilles, au cours de leur manipulation en vue de leur installation chez l'usager, voire en cours de leur entreposage chez ce dernier ou chez les distributeurs, de telles bouteilles sont soumises à de multiples agressions qui en altèrent le caractère esthétique voire leur tenue mécanique en cas d'usure prononcée.It has also been observed that during their life cycle, such cylinders for pressurized gases are subjected to multiple handling during which these bottles are either interlocked relative to each other, especially in the filling phase and Like these bottles, during their handling for installation at the user's premises, or even during storage at the user's premises or at the distributor's, such bottles are subject to multiple attacks that alter their aesthetics or even their mechanical strength in case of pronounced wear.
Pour limiter les zones d' entrechoquement et donc d' usure périphérique, il est assez courant de prévoir, en périphérie de ces bouteilles de gaz, des bourrelets périphériques, plus particulièrement exposés aux agressions de frottement de chocs ou similaires. Il n'empêche, que ces bourrelets font partie intégrante de l'enveloppe de protection et que l'on n'a d'autre choix que de remplacer la bouteille de gaz si on souhaite lui redonner un aspect plus esthétique . C'est donc dans une première démarche inventive que l'on a imaginé une bouteille pour gaz sous pression comportant une enveloppe de protection extérieure composée d' au moins trois parties que l'on vient assembler autour du réservoir métallique, ceci de manière irréversible, autrement dit de manière non démontable sans destruction de l'une de ces parties.To limit the zones of interception and therefore of peripheral wear, it is quite common to provide peripheral peripheries on the periphery of these gas cylinders, more particularly exposed to the aggressions of shock friction. or the like. Nevertheless, these beads are an integral part of the protective envelope and we have no choice but to replace the gas bottle if we want to restore a more aesthetic appearance. It is therefore in a first inventive step that we have imagined a bottle for pressurized gas comprising an outer protective envelope composed of at least three parts that are assembled around the metal reservoir, this irreversibly, in other words, in a manner that can not be dismantled without destroying one of these parts.
Dans une seconde démarche inventive, l'on a pensé que la partie à détruire et donc à remplacer en cas de démontage pour le contrôle du réservoir pouvait être une partie périphérique plus particulièrement prévue pour protéger le réservoir contre les chocs, donc la partie la plus sollicitée en cours de cycle de vie de la bouteille de gaz .In a second inventive step, it was thought that the part to be destroyed and therefore to be replaced in case of disassembly for the control of the tank could be a peripheral part more particularly intended to protect the tank against shocks, so the most solicited during the life cycle of the gas cylinder.
Plus particulièrement, l'on a imaginé que cette partie périphérique , sous forme du verrou virole comporte une zone de découpage destinée à favoriser l'engagement d'un outil de découpe sans blesser le réservoir.More particularly, it has been imagined that this peripheral portion, in the form of the ferrule lock has a cutting zone intended to promote the engagement of a cutting tool without hurting the reservoir.
Finalement, en remplaçant simplement la virole, après vérification du réservoir, il est possible de rénover, à moindre coût, l'aspect esthétique de la bouteille de gaz.Finally, by simply replacing the ferrule, after checking the tank, it is possible to renovate, at lower cost, the aesthetic appearance of the gas cylinder.
A cet effet, l'invention concerne une bouteille de gaz sous pression comprenant un réservoir, notamment métallique contenu dans une enveloppe de protection extérieure comportant au moins une embase formant le piètement de la bouteille et une partie formant couvercle, caractérisée par le fait que ladite enveloppe de protection extérieure comporte encore un bandeau périphérique destiné à être emmanché au-dessus du réservoir et comportant, à ses extrémités supérieure et inférieure, des moyens de liaison conçus aptes à coopérer avec des moyens de liaison complémentaires dont sont pourvus, respectivement, en bordure supérieure et en bordure inférieure, l'embase et la partie formant couvercle ces moyens de liaison étant conformer pour empêcher un déboitement dans le sens axial et autoriser un déboitement radial du bandeau avec l'embase et la partie formant couvercle, ledit bandeau comportant encore au moins une zone de découpe axiale .For this purpose, the invention relates to a bottle of pressurized gas comprising a tank, in particular a metal tank contained in an outer protective casing comprising at least one base forming the base of the bottle and a lid part, characterized in that said outer protective envelope further comprises a peripheral strip intended to be fitted above the tank and having, at its upper and lower ends, connecting means designed to cooperate with complementary connecting means which are provided, respectively, along upper and lower edge, the base and the cover portion these connecting means being conformed to prevent a disengagement in the axial direction and allow a radial disengagement of the strip with the base and the cover portion, said strip further comprising at least one axial cutting zone.
Les avantages découlant de la présente invention consistent en ce que pour le montage de l'enveloppe de protection extérieure autour du réservoir, sur ce dernier est engagé le bandeau de protection périphérique sur les extrémités supérieure et inférieure duquel vient ensuite se fixer l'embase de la partie formant couvercle de cette enveloppe. Si, ces derniers, préférentiellement conçus en un matériau synthétique moulé peuvent intégrer un certain nombre de caractéristiques fonctionnelles, par exemple en ce qui concerne l'embase, former le piètement de la bouteille tandis que la partie formant couvercle peut recevoir une ou plusieurs poignées favorisant la préhension, le bandeau périphérique peut adopter, avantageusement, une forme plus simple pour un coût de fabrication et de moulage moindre .The advantages deriving from the present invention consist in that for the mounting of the outer protection envelope around the reservoir, on the latter is engaged the peripheral protection strip on the upper and lower ends of which is then fixed the base of the cover portion of this envelope. If the latter, preferably designed in a molded synthetic material can incorporate a number of functional characteristics, for example as regards the base, form the base of the bottle while the lid portion can receive one or more handles favoring the gripping, the peripheral strip can adopt, advantageously, a simpler form for a manufacturing cost and less molding.
De la même manière, si ce bandeau est préférentiellement réalisé en un matériau présentant une certaine souplesse de manière à favoriser l'absorption des chocs, les embases et la partie formant couvercle peuvent, elles, éventuellement être conçues en un matériau intégrant des charges favorisant leur résistance mécanique, notamment leur tenue à l'usure.In the same way, if this strip is preferably made of a material having a certain flexibility so as to promote the absorption of shocks, the bases and the lid part may, they possibly be designed in a material incorporating charges promoting their mechanical resistance, especially their resistance to wear.
En cas de nécessité de contrôle du réservoir de la bouteille de gaz , il est procédé au découpage donc à la destruction du bandeau périphérique constitué d'une pièce d'un moindre coût de fabrication mais qui , pour autant, de par le choix d'une couleur adaptée, peut contribuer à l'aspect esthétique de la bouteille de gaz . Ce bandeau étant périodiquement remplacé pour contrôle du réservoir, il en résulte des bouteilles de gaz restant constamment dans un état de présentation optimal .If it is necessary to check the tank of the gas cylinder, it is proceeded to the cutting and destruction of the peripheral strip consisting of a coin of a lower manufacturing cost but, for all that, by the choice of a suitable color, can contribute to the aesthetic appearance of the gas bottle. This strip is periodically replaced for tank control, resulting in gas cylinders always remaining in a state of optimal presentation.
Selon encore un autre avantage de la présente invention, une telle enveloppe de protection pour bouteilles de gaz présente encore l'avantage qu'au travers d'une gamme de bandeaux adaptés, il est ajustable à des réservoirs de différents volumes sans remettre en cause les composants de fabrication les plus onéreux que sont l'embase et la partie formant couvercle.According to yet another advantage of the present invention, such a protective envelope for gas bottles still has the advantage that through a range of adapted bands, it is adjustable to tanks of different volumes. without calling into question the most expensive manufacturing components that are the base and the cover portion.
D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à un exemple de réalisation donné à titre indicatif et non limitatif.Other objects and advantages of the present invention will become apparent from the following description relating to an exemplary embodiment given by way of indication and not limitation.

La présente invention concerne, à la fois, une enveloppe de protection pour réservoir destiné à contenir un gaz sous pression et une bouteille de gaz comportant une telle enveloppe . A ce propos , une bouteille de gaz 1 comporte un réservoir 2 généralement en forme de bonbonne dont les extrémités sont configurées en forme de demi-sphères, de sphères ou d'ellipses, l'extrémité supérieure 3 étant habituellement pourvue d'une ouverture 4 pour la réception, habituellement, d'un robinet détendeur (non visible sur les dessins) .The present invention relates, at the same time, to a tank protective casing for containing a gas under pressure and a gas cylinder having such a casing. In this regard, a gas cylinder 1 comprises a reservoir 2 generally bottle-shaped whose ends are configured in the form of half-spheres, spheres or ellipses, the upper end 3 is usually provided with an opening 4 for reception, usually a valve regulator (not visible in the drawings).
Ce réservoir 2 est contenu dans une enveloppe de protection extérieure 5 comportant une embase 6 formant piètement pour cette bouteille de gaz 1 en venant coiffer l'extrémité inférieure 7 du réservoir 2 , une partie formant couvercle 8 prévue pour coiffer l'extrémité supérieure 3 du réservoir 2. Ainsi, cette partie formant couvercle 8 comporte, elle aussi, une ouverture 9 coïncidant avec celle 4 du réservoir 2 pour le passage du robinet détendeur . A noter, à ce propos, que cette partie formant couvercle 8 est équipée avantageusement, de moyens de préhension 10. Ceux-ci peuvent adopter différentes formes de réalisations telles qu'un rebord annulaire pourvu d' ouvertures permettant de saisir aisément la bouteille de gaz 1. Ces moyens de préhension 10 peuvent encore se présenter sous forme d'une ou, préférentiellement, plusieurs poignées 11 réparties autour de l'ouverture 9.This reservoir 2 is contained in an outer protective envelope 5 comprising a base 6 forming a base for this gas cylinder 1 by capping the lower end 7 of the reservoir 2, a cover portion 8 designed to cap the upper end 3 of the tank 2. Thus, this cover portion 8 also has an opening 9 coinciding with that 4 of the tank 2 for the passage of the expansion valve. It should be noted, in this connection, that this cover portion 8 is advantageously equipped with gripping means 10. These can adopt various embodiments such as an annular flange provided with openings making it easy to grasp the gas bottle. 1. These gripping means 10 may also be in the form of one or, preferably, several handles 11 distributed around the opening 9.
Ainsi, dans le mode de réalisation correspondant au dessin ci-joint, l'on distingue deux poignées 11 diamétralement opposées de manière à assurer par là même une protection du robinet détendeur venant à être disposé au centre , au droit de l'ouverture 9.Thus, in the embodiment corresponding to the attached drawing, there are two diametrically opposed handles 11 so as to thereby ensure a protection of the regulator valve to be arranged in the center, to the right of the opening 9.
Quant à l'embase 6, formant piètement, elle comporte, là encore, avantageusement, au niveau de sa face inférieure 12, un rebord sensiblement annulaire 13 destiné à venir au contact avec le sol en assurant la stabilité de la bouteille de gaz 1.As for the base 6, forming a base, it comprises, again, advantageously, at its lower face 12, a substantially annular rim 13 intended to come into contact with the ground ensuring the stability of the gas cylinder 1.
Selon une particularité de l' invention , cette embase 6 peut, elle aussi, être pourvue de moyens de préhension 14 destinés à faciliter la préhension de la bouteille de gaz 1 et favoriser son transbordement dans ou depuis un coffre de voiture , voire son chargement sur un camion de transport assurant l'acheminement de cette bouteille de gaz depuis le site de remplissage sur les sites de distribution .According to a feature of the invention, this base 6 can also be provided with gripping means 14 for facilitating the gripping of the gas cylinder 1 and facilitate its transfer in or from a car trunk, or even its loading on a transport truck ensuring the delivery of this gas cylinder from the filling site to the distribution sites.
Selon un mode de réalisation préférentiel , de tels moyens de préhension 14 consistent en au moins un décrochement 15 sur le pourtour périphérique 16 de l'embase 6 identifiant l'emplacement, au niveau de la face inférieure 12 de cette dernière, d'un évidement 17 pour permettre à un usager de saisir, à la manière d'une poignée la bouteille de gaz 1 au niveau de cette embase 6. Bien évidemment, sur ce pourtour périphérique 16 de cette embase 6 peuvent, ainsi, être prévus plusieurs décrochements 15 pour permettre à cet usager de saisir la bouteille de gaz par différents endroits au niveau de l' embase 6. D'ailleurs, de manière préférentielle, ce ou ces décrochements 15 se situent avantageusement dans le même alignement vertical que la ou les poignées 11 dont est pourvue, la partie formant couvercle 8.According to a preferred embodiment, such gripping means 14 consist of at least one recess 15 on the periphery 16 of the base 6 identifying the location, at the lower face 12 of the latter, a recess 17 to allow a user to grasp, in the manner of a handle gas bottle 1 at the base 6. Of course, on this peripheral periphery 16 of this base 6 can, thus, be provided several recesses 15 to allow this user to enter the gas cylinder by different locations at the base 6. Moreover, preferably , or these recesses 15 are advantageously in the same vertical alignment as the handle or handles 11 which is provided, the cover portion 8.
On note, là encore, que des décrochements 18 similaires peuvent être ménagés au niveau du rebord annulaire 13 facilitant à l'usager le passage de ses doigts sous ce dernier au droit des décrochements 15.Here again, it is noted that similar recesses 18 may be provided at the level of the annular flange 13 facilitating the user the passage of his fingers under the latter to the right of the recesses 15.
De tels décrochements 18 au niveau du rebord annulaire 13 évitent encore que dans ces zones de préhension de la bouteille de gaz 1 celle-ci repose directement au sol.Such recesses 18 at the annular flange 13 further avoid that in these gripping areas of the gas cylinder 1 it rests directly on the ground.
L'enveloppe de protection 5 comporte encore un bandeau périphérique 19 destiné à être emmanché au-dessus du réservoir 2 et comportant, à ses extrémités supérieure 20 et inférieure 21, des moyens de liaison 22 conçus aptes à coopérer avec des moyens de liaison complémentaires 23 dont sont pourvus, respectivement, en bordure supérieure 24 et en bordure inférieure 25, l'embase 6 et la partie formant couvercle 8 pour assurer leur solidarisation irréversible au moins dans le sens axial et réversible dans le sens sensiblement radial . En d'autres termes, les moyens de liaisons 22 associés aux moyens de liaison complémentaires 23, permettent d'une part, d'empêcher, voire d'interdire, un déboitement dans le sens axial du bandeau 19 et de l'embase 6 et/ou du bandeau 19 et de la partie formant couvercle 8 et, d'autre part, d'autoriser un déboitement dans le sens radial du bandeau 19 et de l'embase 6 et/ou du bandeau 19 et de la partie formant couvercle 8.The protective envelope 5 further comprises a peripheral strip 19 intended to be fitted above the tank 2 and having, at its upper 20 and lower 21 ends, connecting means 22 designed capable of cooperating with complementary connecting means 23 which are provided, respectively, in the upper edge 24 and lower edge 25, the base 6 and the cover portion 8 to ensure their irreversible joining at least in the axial direction and reversible in the substantially radial direction. In other words, the connecting means 22 associated with the complementary connecting means 23, on the one hand, prevent or even prohibit a disengagement in the axial direction of the strip 19 and the base 6 and and / or the strip 19 and the cover portion 8 and, secondly, to allow a radial clearance of the strip 19 and the base 6 and / or the strip 19 and the cover portion 8 .
Plus particulièrement, les moyens de liaison 22 et les moyens de liaison complémentaires 23 sont conformés pour empêcher un déboitement dans le sens axial et autoriser un déboitement radial du bandeau 19 avec l'embase 6 et la partie formant couvercle 8. A ce propos , on remarquera que la partie formant couvercle 8, le bandeau périphérique 19 et l'embase 6 forme un ensemble non démontable sans destruction du bandeau périphérique 19.More particularly, the connecting means 22 and the complementary connecting means 23 are shaped to prevent axial disengagement and allow radial disengagement of the strip 19 with the base 6 and the cover portion 8. In this regard, it will be noted that the cover portion 8, the peripheral strip 19 and the base 6 form a non-removable assembly without destruction of the peripheral strip 19.
Ainsi, ces moyens de liaison 22 peuvent être conçus pour coopérer avec les moyens de liaison complémentaires 23 par emboîtement axial du bandeau 19 sur l'embase 6 et de la partie formant couvercle 8 sur ce bandeau 19.Thus, these connecting means 22 may be designed to cooperate with the complementary connecting means 23 by axially interlocking the strip 19 on the base 6 and the cover portion 8 on the strip 19.
Par conséquent, ces moyens de liaison 22 peuvent se présenter, aux extrémités supérieure 20 et/ou inférieure 21 du bandeau 19, intérieurement à ce dernier sous forme d'un rebord d'accrochage 26, conçu apte à coopérer avec un rebord d'accrochage similaire 27, formant les moyens de liaison 23, que comporte, extérieurement, en bordure supérieure 24 et en bordure inférieure 25, respectivement, l'embase 6 et la partie formant couvercle 8.Therefore, these connecting means 22 may be present, at the upper ends 20 and / or lower 21 of the strip 19, internally to the latter in the form of a fastening flange 26, designed capable of cooperating with a hooking flange similar 27, forming the connecting means 23, that comprises, externally, at the upper edge 24 and at the bottom edge 25, respectively, the base 6 and the cover portion 8.
A noter, à ce propos, que l'on peut encore imaginer une inversion de l'implantation de ces rebords d'accrochage 26, 27 sur le bandeau 19 et sur l'embase 6 et/ou sur la partie formant couvercle 8. En particulier, le rebord d'accrochage 27 peut être ménagé intérieurement à cette embase 6 et cette partie formant couvercle 8, le rebord d'accrochage 26 aux extrémités 20, 21 du bandeau 19 se situant alors extérieurement à ce dernier.Note, in this regard, that one can still imagine a reversal of the implementation of these hooking edges 26, 27 on the strip 19 and on the base 6 and / or on the cover portion 8. In In particular, the hooking flange 27 may be provided internally to this base 6 and this cover portion 8, the hooking flange 26 at the ends 20, 21 of the strip 19 then being external to the latter.
A noter, cependant, que le bandeau 19 monté sur le réservoir 2 est préférentiellement défini de section externe 28 au moins égale préférentiellement supérieure à la section de l'embase 6 et de la partie formant couvercle 8, ceci de manière apte à absorber les chocs que peuvent subir de telles bouteilles de gaz 1 en périphérie .Note, however, that the strip 19 mounted on the reservoir 2 is preferably defined outer section 28 at least preferably equal to the greater the section of the base 6 and the cover portion 8, this in a manner capable of absorbing shocks that can suffer such gas bottles 1 at the periphery.
A noter encore, que ce bandeau 19 ne comporte pas nécessairement dans toute sa globalité une section plus importante par rapport à l'embase 6 et la partie formant couvercle 8. En effet, ce bandeau 19 peut être pourvu de nervures périphériques définies aptes à assurer cette fonction d'absorption des chocs de la bouteille de gaz 1. Pour en revenir aux rebords d'accrochage 26, 27, ceux-ci peuvent être configurés en forme de redans, autrement dit en forme d'hameçons empêchant toute désolidarisation de l'embase 6 ou de la partie formant couvercle 8 de ce bandeau périphérique 19.It should be further noted that this strip 19 does not necessarily comprise in its entirety a larger section relative to the base 6 and the cover portion 8. Indeed, this strip 19 may be provided with defined peripheral ribs capable of ensuring this function of shock absorption of the gas cylinder 1. To return to the hooking edges 26, 27, they can be configured in the form of redans, in other words in form of hooks preventing any separation of the base 6 or the cover part 8 of this peripheral strip 19.
Inversement, des chanfreins peuvent être ménagés selon le cas aux extrémités supérieure 20 et inférieure 21 du bandeau 19 ou en bordure supérieure 24 de l'embase 6 et/ou en bordure inférieure 25 de la partie formant couvercle 8 pour favoriser l'emboîtement des composants et permettre les coopérations des rebords d'accrochage 26, 27. Selon encore un autre mode de réalisation, les moyens de liaison 22 peuvent être conçus pour coopérer avec les moyens de liaison complémentaires 23 par rétreint du bandeau 19 sur le réservoir 2.Conversely, chamfers may be provided as appropriate at the upper and lower ends 21 of the strip 19 or at the upper edge 24 of the base 6 and / or at the bottom edge 25 of the cover portion 8 to promote the interlocking of the components. and allow the hooking edges 26, 27 to cooperate. According to yet another embodiment, the connecting means 22 may be designed to cooperate with the complementary connection means 23 by swaging of the strip 19 on the tank 2.
Avantageusement le bandeau 19 peut être en matériau thermoplastique.Advantageously, the strip 19 may be made of thermoplastic material.
Il n'empêche que les moyens de liaison 22 et ceux complémentaires 23 peuvent, là encore, adopter la forme de rebords d'accrochages 26, 27. Plus particulièrement, si le rebord d'accrochage 26 se présente alors sous forme d'une nervure continue ou discontinue intérieurement au bandeau 19, sensiblement aux extrémités supérieure 20 et inférieure 21 de ce dernier, le rebord d'accrochage 27, en bordure supérieure 24 de l'embase 6 et en bordure inférieure de l'embase 25 de la partie formant couvercle 8 doit emprunter la forme d'une rainure périphérique , là encore continue ou discontinue .Nevertheless, the connecting means 22 and the complementary means 23 may, again, take the form of hooking edges 26, 27. More particularly, if the hooking flange 26 is then in the form of a rib Continuous or internally discontinuous to the strip 19, substantially at the upper ends 20 and lower 21 thereof, the hooking flange 27, the upper edge 24 of the base 6 and the lower edge of the base 25 of the lid portion 8 must take the form of a peripheral groove, again continuous or discontinuous.
Selon l'invention, le bandeau périphérique 19 comporte, en combinaison, au moins une zone de découpe axiale 29 identifiable par un opérateur pour assurer le découpage de ce bandeau 19 et permettre son retrait, grâce aux moyens de liaison 22 et ceux complémentaires 23 prévus à même d' assurer une liaison réversible par un déplacement dans une direction sensiblement radiale des uns par rapport aux autres .According to the invention, the peripheral strip 19 comprises, in combination, at least one axial cutting area 29 identifiable by an operator to ensure the cutting of this strip 19 and allow its removal, thanks to the connecting means 22 and complementary 23 provided capable of providing a reversible connection by displacement in a substantially radial direction relative to each other.
Justement, le découpage du bandeau 19 permet de désolidariser ce dernier et donc d' obtenir ce déplacement dans une direction sensiblement radiale des moyens de liaison 22 par rapport à ceux complémentaires 23. Cette ou ces zones de découpe axiale 29 sont conçues de manière visible, extérieurement au bandeau de protection 19, par exemple sous forme d'une légère dépression s'étendant sensiblement depuis l'extrémité supérieure 20 jusqu'à l'extrémité inférieure 21 du bandeau 19 ou, au contraire, par un bossage axial 30 comme représenté sur les figures, les lignes de jonction 31 de ce bossage axial 20 identifiant la zone de découpage du bandeau 19.Precisely, the cutting of the strip 19 allows to separate the latter and thus to obtain this displacement in a substantially radial direction of the connecting means 22 relative to those complementary 23. This or these axial cutting zones 29 are designed visibly, externally to the protective strip 19, for example in the form of a slight depression extending substantially from the upper end 20 to the lower end 21 of the strip 19 or, conversely, by an axial boss 30 as shown in the figures, the junction lines 31 of this axial boss 20 identifying the cutting area of the strip 19.
Préfèrentlellement la ou les zones de découpe axiale 29 comportent une ligne de prédécoupage permettant de faciliter le découpage du bandeau 19.Preferably, the axial cutting zone or zones 29 comprise a pre-cutting line making it easier to cut the strip 19.
De manière avantageuse, à hauteur de cette ou ces zones de découpe axiale 29, un espacement 32 axial est respecté entre le bandeau 19 et le réservoir 2 de manière à permettre l'engagement d'un outil de coupe dudit bandeau 19 en évitant de blesser le réservoir 2.Advantageously, at this or these axial cutting zones 29, an axial spacing 32 is respected between the strip 19 and the reservoir 2 so as to allow the engagement of a cutting tool of said strip 19 while avoiding injuring the tank 2.
Les avantages découlant de la présente invention consistent en ce que la bouteille de gaz peut être pourvue d'une enveloppe de protection empêchant tout accès, qui ne puisse être identifié, au réservoir de cette bouteille. Ainsi, à chaque opération de remplissage, l'on peut s'assurer de l'intégrité de ce réservoir et donc, de son étancheité .The advantages of the present invention are that the gas cylinder can be provided with a protective envelope preventing access, which can not be identified, the tank of this bottle. Thus, at each filling operation, one can ensure the integrity of the tank and therefore, its tightness.
Pour autant, le contrôle visuel de ce dernier reste possible au travers de la destruction d'une pièce dont le remplacement reste d'un prix de revient contenu tout en assurant la rénovation de l'enveloppe de protection extérieure d'une telle bouteille de gaz . However, the visual control of the latter remains possible through the destruction of a part whose replacement remains a cost price content while ensuring the renovation of the outer protective envelope of such a gas cylinder .
