Description

Chapeau de protection pour récipient et récipient pourvu d'un tel chapeau Protective cap for a receptacle and receptacle provided with such a cap
La présente invention concerne un chapeau de protection pour récipient ainsi qu'un récipient pourvu d'un tel chapeau.The present invention relates to a protective cap for a container and a container provided with such a cap.
L'invention concerne plus particulièrement un chapeau de protection pour récipient de fluide, en particulier pour bouteille de gaz sous pression, comprenant un corps de capotage et une bague formant une interface de montage du corps de capotage sur le récipient.The invention relates more particularly to a protective cap for a fluid container, in particular for a pressurized gas bottle, comprising a casing body and a ring forming an interface for mounting the casing body on the container.
La protection contre les chocs et les agressions diverses des robinets ou robinets détendeurs équipant les bouteilles de fluide sous pression est réalisée en général par un accessoire nommé chapeau qui peut être « ouvert » ou « fermé » (cf. norme NF E29-640). Les caractéristiques générales et les performances de ces chapeaux sont décrites par exemple dans la norme NF EN 962.The protection against shocks and various attacks of valves or pressure-reducing valves fitted to pressurized fluid cylinders is generally performed by an accessory called a cap which can be "open" or "closed" (see NF E29-640 standard). The general characteristics and the performances of these hats are described for example in standard NF EN 962.
Un chapeau fermé offre une protection complète du robinet lorsqu'il est en place mais doit être retiré pour donner accès audit robinet. Ainsi, le chapeau fermé ne protège plus le robinet lorsque la bouteille est en cours d'utilisation.A closed cap provides complete valve protection when in place but must be removed to provide access to the faucet. Thus, the closed cap no longer protects the valve when the bottle is in use.
Les chapeaux ouverts sont relativement simples lorsqu'ils sont conçus pour protéger des robinets classiques. En général, les chapeaux sont plus sophistiqués pour les robinets à détendeurs intégrés (RDI) du fait de leurs dégagements autorisant l'accès aux commandes et la visibilité de manomètres (cf. à titre d'exemple le document FR 2 774 452 A1 ). La conception d'un chapeau doit prendre en compte plusieurs contraintes parfois contradictoires. Ainsi, pour assurer son rôle de protection tout en permettant l'accès au robinet et en assurant une bonne ergonomie d'utilisation (pour le transport de la bouteille comme pour le remplissage ou le soutirage du fluide), le chapeau doit être le plus englobant possible. De plus, pour permettre l'inspection et la maintenance du robinet le chapeau doit être très ouvert et/ou amovible. Un chapeau amovible est intéressant pour la maintenance du robinet mais aussi pour la maintenance du chapeau lui- même (opérations de peinture, de nettoyage, de réparation ou de remplacement). Cependant, la pose et la dépose du chapeau doivent être relativement simples et la fixation doit être suffisamment fiable pour éviter le desserrage ou la perte du chapeau pendant les manutentions et le transport. Pour permettre l'accès aux commandes et la visibilité des manomètres ou autres composants, le chapeau doit être positionné précisément en hauteur comme angulairement relativement au robinet.Open hats are relatively simple when designed to protect conventional faucets. In general, the caps are more sophisticated for valves with integrated regulators (RDI) because of their clearances allowing access to the controls and the visibility of manometers (see for example the document FR 2 774 452 A1). The design of a hat must take into account several sometimes contradictory constraints. Thus, to ensure its role of protection while allowing access to the valve and ensuring good ergonomics of use (for the transport of the bottle as for filling or withdrawal of the fluid), the hat must be the most encompassing possible. In addition, to allow inspection and maintenance of the valve the cap must be very open and / or removable. A removable cap is interesting for the maintenance of the tap but also for the maintenance of the hat itself (painting, cleaning, repair or replacement operations). However, the installation and removal of the cap must be relatively simple and the attachment must be sufficiently reliable to prevent loosening or loss of the cap during handling and transport. To allow access to controls and visibility of manometers or other components, the cap must be positioned precisely in height as angularly relative to the valve.
Enfin, le chapeau doit s'accommoder du type de fixation disponible sur la bouteille qu'il équipe (comme par exemple une « collerette » selon la norme NF EN 962). Cependant, il existe différents type de fixation pour les chapeaux de protection : des collerettes lisses, des collerettes filetées avec différents diamètres (notamment 78 mm et 80 mm). Les collerettes ont en général un diamètre extérieur supérieur à l'enveloppe spatiale de la plupart des robinets classiques. Ceci permet de monter le chapeau sur un robinet déjà monté sur le récipient. Cependant, un grand nombre de robinets, et notamment de robinet à détendeurs intégrés (RDI), ont une enveloppe spatiale supérieure au diamètre extérieur des collerettes.Finally, the hat must accommodate the type of fastener available on the bottle it equips (such as for example a "collar" according to standard NF EN 962). However, there are different types of fasteners for the protective caps: smooth collars, threaded collars with different diameters (in particular 78 mm and 80 mm). The collars generally have an outer diameter greater than the space envelope of most conventional faucets. This allows to mount the cap on a tap already mounted on the container. However, a large number of valves, and in particular integrated regulator valves (RDI), have a spatial envelope greater than the outer diameter of the flanges.
Ceci a pour conséquence qu'il faut soit prévoir un chapeau démontable pouvant être assemblé sur la bouteille sans démonter le robinet, soit monter le robinet après le chapeau. Dans ce dernier cas, cela interdit le démontage du chapeau sans le démontage préalable du robinet. Il convient de signaler que le montage du robinet est une opération délicate du fait notamment de la nécessité de respecter un couple de serrage relativement à la bouteille. Le démontage du robinet peut conduire quant à lui à endommager le robinet, par exemple par une usure du filet conique de la collerette ou du marquage des surfaces en contact avec l'outil de serrage et de desserrage.This has the consequence that it must either provide a removable cap that can be assembled on the bottle without disassembling the valve, or mount the valve after the cap. In the latter case, it prohibits disassembly of the cap without the prior disassembly of the valve. It should be noted that the mounting of the valve is a delicate operation due in particular to the need to respect a tightening torque relative to the bottle. Disassembly of the valve may lead to damage to the valve, for example by wear of the conical thread of the flange or marking of the surfaces in contact with the clamping tool and loosening.
Le document US 4,880,134 décrit un chapeau de protection lisse qui se fixe sur son récipient au moyen d'une bague d'adaptation taraudée. Cette solution n'est cependant pas adaptée aux robinets dont l'enveloppe spatiale n'entre pas dans le diamètre de la bague d'adaptation.US 4,880,134 discloses a smooth protective cap that attaches to its container by means of a threaded adapter ring. This solution is however not suitable for taps whose spatial envelope does not enter the diameter of the adapter ring.
Selon d'autres solutions connues, le chapeau peut être réalisé en deux parties venant pincer une collerette lisse. Cette solution ne convient cependant pas aux collerettes filetées et n'est adaptée qu'à un seul profil de collerette (diamètre et hauteur).According to other known solutions, the cap can be made in two parts from pinching a smooth collar. This solution, however, is not suitable for threaded flanges and is only suitable for a single flange profile (diameter and height).
Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. A cette fin, le chapeau de protection, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que la bague est fendue, c'est à dire présente une ouverture unique sur sa circonférence prévue pour sa mise en place ou son retrait relativement à un récipient, l'ouverture 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 section d'un récipient ou d'un organe monté sur un récipient tel qu'un robinet.An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above. To this end, the protective cap, which is also in accordance with the generic definition given in the preamble above, is essentially characterized in that the ring is split, ie it has a single opening on its circumference. for its introduction or withdrawal relative to a container, the opening the ring being provided to form, during installation or removal of the ring, a passage for a portion or section of a container or a member mounted on a container such as a tap.

- la bague présente une surface intérieure destinée à être montée sur une surface extérieure d'un récipient et une surface extérieure destinée à coopérer avec une surface d'un corps de capotage pour le montage de ce dernier sur le récipient, la surface intérieure de la bague étant lisse ou présentant des reliefs d'accrochage tels d'un taraudage pour coopérer avec une surface conjuguée d'un récipient,the ring has an inner surface intended to be mounted on an outer surface of a container and an outer surface intended to cooperate with a surface of a rollover body for mounting the latter on the container, the inner surface of the ring being smooth or having hooking reliefs such as a tapping for cooperating with a conjugate surface of a container,
- la surface extérieure de la bague comprend un profil d'accrochage ou de positionnement destiné à coopérer avec un profile complémentaire d'une surface du corps de capotage,the outer surface of the ring comprises a hooking or positioning profile designed to cooperate with a complementary profile of a surface of the cowling body,
- la surface extérieure de la bague comprend au moins un creux et/ou un relief,the outer surface of the ring comprises at least one hollow and / or one relief,
- le corps de capotage comprend au moins deux parties aptes à être solidarisée,the casing body comprises at least two parts capable of being secured,
- le corps de capotage comprend au moins deux parties aptes à être solidarisée de façon à enserrer la bague sur un récipient,- The casing body comprises at least two parts adapted to be secured so as to grip the ring on a container,

- la bague comprend du métal et/ou un alliage métallique et/ou un matériau de type plastique.the ring comprises metal and / or a metal alloy and / or a plastic-type material.
Selon une particularité avantageuse, le corps de capotage peut être fixé sur la collerette au moyen d'une interface comprenant une bague fendue dont la surface intérieure est taraudée pour coopérer avec le filetage de la collerette.According to an advantageous feature, the casing body can be fixed on the flange by means of an interface comprising a split ring whose inner surface is threaded to cooperate with the thread of the flange.
Le profil extérieur de la bague est une surface de révolution qui coopère avec un profil complémentaire situé dans la surface interne du chapeau ou corps de capotage.The outer profile of the ring is a surface of revolution which cooperates with a complementary profile located in the inner surface of the cap or casing body.
La fente de la bague fendue est d'une largeur dimensionnée telle que ladite bague peut être mise en place alors que le robinet ou le robinet à détendeur intégré (RDI) est déjà installé sur la bouteille. De préférence, la collerette est filetée et la bague fendue taraudée. Il est ainsi possible de visser la bague sur la collerette pour la positionner à la hauteur idéale pour le positionnement relatif du chapeau et du robinet ou RDI.The slot of the split ring is of a width dimensioned such that said ring can be put in place while the tap or the integrated regulator valve (RDI) is already installed on the bottle. Preferably, the flange is threaded and the split ring threaded. It is thus possible to screw the ring on the flange to position it at the ideal height for the relative positioning of the cap and the tap or RDI.
Pour faciliter la pose et la dépose du chapeau, celui-ci peut être fractionné en au moins deux parties qui sont d'abord assemblées sans serrage particulier sur la bague. Ceci permet de positionner angulairement le chapeau relativement au robinet. Il convient ensuite de serrer l'assemblage des différentes parties du chapeau ou corps de capotage, pour bloquer concomitamment le chapeau sur la bague fendue et la bague fendue sur la collerette de la bouteille. La bague fendue peut donc être usinée avec un léger jeu par rapport à la collerette ce qui simplifie son usinage et sa mise en place. Ce jeu peut être rattrapé lors du serrage du corps de capotage. Pour augmenter l'effet de serrage entre la bague fendue et la collerette, l'inertie de la bague fendue peut être réduite localement par exemple dans la zone diamétralement opposée à sa fente. A cet effet, il est possible de pratiquer une entaille et/ou un perçage que l'homme de l'art saura disposer pour concilier son efficacité élastique et sa facilité d'obtention.To facilitate the installation and removal of the cap, it can be split into at least two parts that are first assembled without particular tightening on the ring. This allows to angularly position the cap relative to the valve. It is then necessary to tighten the assembly of the different parts of the cap or casing body to concomitantly block the cap on the split ring and the split ring on the collar of the bottle. The split ring can be machined with a slight clearance with respect to the collar which simplifies its machining and implementation. This game can be caught when tightening the rollover body. To increase the clamping effect between the split ring and the collar, the inertia of the split ring can be reduced locally, for example in the region diametrically opposite to its slot. For this purpose, it is possible to to practice a notch and / or piercing that the skilled person will have available to reconcile its elastic efficiency and ease of obtaining.
Pour s'adapter à différents types de bouteilles, un même chapeau peut se monter sur bagues fendues de différentes formes ou tailles intérieures. Une même bague fendue peut également recevoir différents chapeaux. Ceci peut permettre de renouveler des corps de capotage sans changer de la bague fendue d'interface de montage.To fit different types of bottles, the same hat can be mounted on split rings of different shapes or internal sizes. The same split ring can also receive different hats. This can make it possible to renew casing bodies without changing the split mounting interface ring.
Le chapeau peut être utilisé avec des collerettes lisses moyennant l'adoption de bagues fendue adaptées en conséquence. Dans cette variante, la finesse et la précision du positionnement en hauteur de la bague sur la collerette sont légèrement moindres comparées à la solution dans laquelle la bague fendue est taraudée et vissée sur une collerette filetée. Des écarts de hauteur peuvent toutefois être corrigés soit par l'usage de bagues fendues différentes si les écarts sont génériques soit par l'usage de cales d'épaisseur fendues comme la bague et introduites sous cette dernière pour obtenir la cote en hauteur souhaitée.The cap can be used with smooth collars by adopting adapted split rings accordingly. In this variant, the fineness and accuracy of the height positioning of the ring on the flange are slightly less compared to the solution in which the split ring is threaded and screwed onto a threaded flange. However, differences in height can be corrected either by the use of different split rings if the differences are generic or by the use of slotted shims like the ring and introduced under it to obtain the desired height dimension.
Une autre solution peut consister à utiliser des bagues fendues présentant un profil extérieur décentré par rapport à l'épaisseur. C'est à dire que la partie en saillie ou en creux de la surface extérieure de la bague est plus proche de l'un des flancs (supérieur ou inférieur) de la bague que de l'autre flanc (inférieur ou supérieur) de la bague.Another solution may be to use split rings having an outer profile off-center with respect to the thickness. That is, the protruding or recessed part of the outer surface of the ring is closer to one of the flanks (upper or lower) of the ring than to the other flank (lower or upper) of the ring. Ring.
Ainsi, en montant la bague avec le flanc à relief vers le haut, le chapeau se trouvera monté en position relativement haute. Réciproquement, en montant le flanc à relief vers le haut, le chapeau se trouve monté en position relativement basse. Pour faciliter le choix de la bague fendue et son orientation, un gabarit portant différentes encoches peut être réalisé aisément. En variante, des moyens de métrologie automatique pourront guider l'opérateur.Thus, by mounting the ring with the flank raised to the top, the cap will be mounted in a relatively high position. Conversely, by raising the raised flank upwards, the hat is mounted in a relatively low position. To facilitate the choice of the split ring and its orientation, a template with different notches can be made easily. Alternatively, automatic metrology means can guide the operator.
Pour des bouteilles à collerette lisse et à blocage par un anneau d'arrêt (du type « circlips ») telles que celle décrite dans le document US 3776412, le blocage en translation de la bague fendue peut être sécurisé par un « circlips » identique à celui utilisé avec le chapeau tournant. Le serrage du corps de capotage fixant alors la position angulaire et annihilant le jeu entre le chapeau et la bouteille.For bottles with a smooth flange and with a locking ring (of the "circlip" type) such as that described in document US 3776412, the locking in translation of the split ring can be secured by a "circlip" identical to the one used with the rotating cap. The tightening of the casing body then fixing the angular position and annihilating the clearance between the cap and the bottle.
D'autres particularités et avantages apparaîtront à la lecture de la description ci-après, faite en référence aux figures dans lesquelles : - la figure 1 représente une vue en perspective de la partie supérieure d'une bouteille de gaz sous pression munie d'un robinet à détendeur intégré et dépourvue de chapeau de protection,Other particularities and advantages will appear on reading the following description, made with reference to the figures in which: FIG. 1 represents a perspective view of the upper part of a pressurized gas cylinder provided with an integrated pressure reducing valve and without a protective cap,
- les figures 2 à 6 représentent des vues en perspectives illustrant une succession d'étapes de montage, sur le récipient de la figure 1 , d'un chapeau de protection conforme à un exemple de réalisation de l'invention.- Figures 2 to 6 show perspective views illustrating a succession of mounting steps on the container of Figure 1, a protective cap according to an embodiment of the invention.
- la figure 7 représente une vue en perspective et agrandie du récipient de la figure 1 équipé d'un chapeau de protection monté et conforme à un exemple de réalisation de l'invention.- Figure 7 shows a perspective view and enlarged container of Figure 1 equipped with a protective cap mounted and according to an exemplary embodiment of the invention.
La figure 1 représente une bouteille 1 de gaz sous pression équipée d'un robinet 2 à détendeur intégré comprenant, classiquement, des moyens de commande et des manomètres.FIG. 1 represents a bottle 1 of pressurized gas equipped with an integrated regulator valve 2 comprising, conventionally, control means and manometers.
Une succession d'étapes du montage d'un exemple de réalisation d'un chapeau de protection selon l'invention va à présent être décrit en référence aux figures 2 à 7.A succession of steps of mounting an exemplary embodiment of a protective cap according to the invention will now be described with reference to Figures 2 to 7.
En se référant à présent à la figure 2, une bague fendue 3 est présentée dans une position permettant sa mise en place par translation autour de la collerette 4 de la bouteille 1 (flèche T). Plus précisément, la bague 3 peut être insérée ou enfilée autour du robinet et/ou au sommet de la collerette 4 de la bouteille 1 via une translation de la bague 3 selon une direction sensiblement perpendiculaire à l'axe vertical de la bouteille 1. C'est-à-dire que la bague 3 peut être placée autour de la base du robinet 2 ou au niveau de la partie supérieure de la collerette 4 selon une direction sensiblement transversale à l'axe la bouteille 1.Referring now to Figure 2, a slotted ring 3 is presented in a position allowing its implementation by translation around the flange 4 of the bottle 1 (arrow T). More specifically, the ring 3 can be inserted or threaded around the valve and / or at the top of the flange 4 of the bottle 1 via a translation of the ring 3 in a direction substantially perpendicular to the vertical axis of the bottle 1. C that is to say that the ring 3 can be placed around the base of the valve 2 or at the top of the collar 4 in a direction substantially transverse to the axis of the bottle 1.
La surface intérieure 23 de la bague 3 est taraudée pour coopérer avec un filetage conjugué formé sur la collerette 4. La surface extérieure 33 de la bague 3 comporte une nervure périphérique destinée à coopérer avec une gorge conjuguée formée sur une surface intérieure d'un corps de capotage destiné à être monté sur la bague 3 (cf. ci-après).The inner surface 23 of the ring 3 is threaded to cooperate with a conjugated thread formed on the collar 4. The outer surface 33 of the ring 3 comprises a peripheral rib intended to cooperate with a conjugate groove formed on an inner surface of a body cowling intended to be mounted on the ring 3 (see below).
La largeur de la fente 13 de la bague 3 est dimensionnée pour permettre le passage du robinet au travers de la fente 13 vers l'intérieur de la bague 3. Lorsque la bague 3 fendue est placée au dessus de la collerette 4 de la bouteille 1 , les axes de la bouteille 1 et de la bague 3 sont sensiblement confondus. Dans cette position, la bague 3 peut être vissée sur la collerette 4 par rotation (flèche R figureThe width of the slot 13 of the ring 3 is dimensioned to allow the passage of the valve through the slot 13 towards the inside of the ring 3. When the split ring 3 is placed above the collar 4 of the bottle 1 , the axes of the bottle 1 and the ring 3 are substantially merged. In this position, the ring 3 can be screwed on the flange 4 by rotation (arrow R figure
3).3).
Les dimensions de la bague 3 peuvent être déterminées avec un jeu suffisant pour rendre le vissage de la bague 3 aisé. En effet, en fin d'assemblage du chapeau, la bague 3, qui a une certaine élasticité du fait de sa fente 13, sera serrée sur la collerette 4 et le jeu sera rattrapé.The dimensions of the ring 3 can be determined with enough clearance to make the ring 3 easy to screw. Indeed, at the end of assembly of the cap, the ring 3, which has a certain elasticity due to its slot 13, will be tight on the flange 4 and the game will be caught.
Les figures 4 et 5 illustrent le positionnement des deux demi-chapeaux 5, 6 qui seront serrés sur la bague 3 fendue par deux vis 7. Les demi-chapeaux 5, 6 comportent à cet effet dans leur partie inférieure une demi-bride 8 dont la surface intérieure est de forme complémentaire de la surface extérieure 33 de la bague 3 (une gorge dans cet exemple de réalisation). Les vis 7 sont prévues pour coopérer avec des alésages taraudés formés au travers des brides 8 des demi- chapeaux 5, 6. Bien entendu, tout autre moyen de fixation des deux demi-chapeau 5, 6 formant le corps de capotage peut être prévu, comme par exemple des goupilles, des agrafes élastiques, des fixations à came comme les roues de bicyclette, des chevilles comme les échafaudages, des clips, des colliers type « attache de câblage », des rivets type « pop ». Le choix du système de fixation sera notamment guidé par la facilité ou la difficulté de démontage visée, la fixation pouvant cumuler une fonction de sceau d'inviolabilité.FIGS. 4 and 5 illustrate the positioning of the two half-caps 5, 6 which will be tightened on the ring 3 split by two screws 7. The half-caps 5, 6 have for this purpose in their lower part a half-flange 8 of which the inner surface is of complementary shape to the outer surface 33 of the ring 3 (a groove in this embodiment). The screws 7 are designed to cooperate with threaded bores formed through the flanges 8 of the half-caps 5, 6. Of course, any other means for fixing the two half-caps 5, 6 forming the cowling body can be provided, such as pins, spring clips, cam fasteners such as bicycle wheels, pegs such as scaffolding, clips, cable ties, pop rivets. The choice of the fastening system will be guided in particular by the ease or difficulty of disassembly referred to, the attachment can accumulate a tamper-proof seal function.
De cette façon, une fois les deux demi-chapeaux 5, 6 serrés autour de la bague 3 montée sur la collerette 4, le chapeau assemblé est solidaire de la bague 3 qui est elle même bloquée sur la collerette 4.In this way, once the two half-caps 5, 6 tight around the ring 3 mounted on the flange 4, the assembled cap is secured to the ring 3 which is itself locked on the flange 4.
La figure 6 illustre des pièces complémentaires possibles pour l'assemblage du chapeau : un pommeau 9 de manutention comportant dans sa partie inférieure une longueur filetée 19, une rondelle 10 et une bride 11 à crénelée taraudée en son centre. La longueur filetée 19 du pommeau 9 peut ainsi être vissée dans la bride 11 crénelée après la mise en place de la bride 11 sous une portion (tiges formant un grillage) constituant la partie supérieure des demi chapeaux 5, 6.FIG. 6 illustrates possible complementary parts for assembling the cap: a handling knob 9 having in its lower part a threaded length 19, a washer 10 and a flange 11 with serrated threaded at its center. The threaded length 19 of the knob 9 can thus be screwed into the flange 11 crenellated after the introduction of the flange 11 in a portion (rods forming a mesh) constituting the upper part of the half-caps 5, 6.
En variante, le pommeau peut être libre en rotation pour faciliter le roulage de la bouteille.Alternatively, the knob may be free to rotate to facilitate the rolling of the bottle.
Ainsi, comme visible à la figure 7, la bride 11 crénelée lie entre elles les parties supérieures des deux demi-chapeaux 5, 6 en coopérant avec la rondelle 10 et le pommeau 9. Ceci confère une bonne rigidité à l'ensemble du chapeau. De préférence, le serrage du pommeau 9 vissé dans la bride 11 crénelée est sécurisé par un des moyens classiques et connus de l'homme de l'art parmi les rondelles élastiques (par exemple du type « Grower » NFE 25215, éventail NFE 27626 , ..), des freins de filet, un contre écrou, un écrou à bague Nylon (DIN 985, « Nylfix ») etc ..Thus, as can be seen in FIG. 7, the crenellated flange 11 connects the upper parts of the two half-caps 5, 6 cooperating with the washer. 10 and the knob 9. This gives a good rigidity to the entire hat. Preferably, the tightening of the knob 9 screwed into the flange 11 crenellated is secured by one of the conventional means and known to those skilled in the art among the spring washers (for example of the type "Grower" NFE 25215, NFE fan 27626, ..), thread locks, a locknut, a nylon ring nut (DIN 985, "Nylfix") etc.
Bien entendu, la liaison mécanique entre les parties supérieures des deux demi-chapeaux 5, 6 n'est pas limitée à l'exemple décrit ci-dessus. Ainsi, par exemple, les parties supérieures des demi-chapeaux 5, 6 peuvent être fixées par tout autre moyen équivalent, par exemple par des systèmes d'accrochage complémentaires portés par les demi-chapeaux 5, 6.Of course, the mechanical connection between the upper parts of the two half-caps 5, 6 is not limited to the example described above. Thus, for example, the upper parts of the half-caps 5, 6 can be fixed by any other equivalent means, for example by complementary fastening systems carried by the half-caps 5, 6.
De la même façon, la structure du chapeau n'est pas limitée à l'exemple de réalisation ci-dessus dans lequel il est formé d'une cage métallique avec de possibles renforts 15, 16 (figure 4). Ainsi, le corps de capotage formant le chapeau peut avoir toute forme et structure de protection, et comprendre tout autre matériau ou combinaison de matériau et notamment du plastique.In the same way, the structure of the cap is not limited to the above embodiment in which it is formed of a metal cage with possible reinforcements 15, 16 (Figure 4). Thus, the cowling body forming the cap may have any form and protective structure, and include any other material or combination of material including plastic.
Par exemple, le corps de capotage peut comprendre une unique partie enveloppante partiellement ouverte et qui vient coopérer avec une bride de fixation. C'est-à-dire que, par rapport à l'exemple de réalisation des figures 2 à 7, l'un des deux demi-chapeaux a une forme plus enveloppante et l'autre demi- chapeau est remplacé uniquement par une pièce de montage (demi-bride par exemple) qui ne participe pas ou peu à la protection du robinet.For example, the cowl body may comprise a single partially open enveloping portion and which cooperates with a fastening flange. That is to say, with respect to the embodiment of FIGS. 2 to 7, one of the two half-hats has a more enveloping shape and the other half-hat is replaced only by a piece of mounting (half-flange for example) which does not participate or little in the protection of the tap.
On conçoit donc aisément que tout en étant de structure simple et peu coûteuse, l'invention présente de nombreux avantages par rapport aux solutions connues. Ainsi, le chapeau objet de l'invention permet à la fois :It is therefore easily conceivable that while being simple and inexpensive structure, the invention has many advantages over known solutions. Thus, the hat object of the invention allows both:
- d'englober au mieux les robinets ou les robinets à détendeurs intégrés- to best encompass faucets or valves with built-in regulators
- de laisser un accès aux commandes et la visibilité des composants devant être vus- to leave access to the controls and the visibility of the components to be seen
- un montage, un positionnement et un démontage aisés sans nécessité de démontage du robinet, une adaptation à un grand nombre de bouteilles différentes tout en conservant une structure relativement standard, Bien entendu l'invention n'est pas limitée aux exemples de réalisations décrits ci-dessus. Ainsi, par exemple, les modes de réalisation ne se limitent pas à un chapeau de protection fixé au moyen d'une bague mais peuvent s'appliquer à tout autre type d'interface de montage d'un corps de capotage sur un récipient. - Easy assembly, positioning and disassembly without the need to disassemble the valve, adapting to a large number of different bottles while maintaining a relatively standard structure, Naturally, the invention is not limited to the embodiments described above. Thus, for example, the embodiments are not limited to a protective cap attached by means of a ring but can be applied to any other type of mounting interface of a casing body on a container.
