Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention est relative au domaine technique des fers à vapeur. La présente invention concerne plus particulièrement les fers à vapeur du type comprenant une chambre de vaporisation ainsi qu'un réservoir destiné à recevoir et à stocker l'eau avant que celle-ci ne soit injectée par différents moyens connus tel que pointeaux, boisseaux ou pompes dans ladite chambre de vaporisation pour y être évaporée.The present invention relates to the technical field of steam irons. The present invention relates more particularly to steam irons of the type comprising a vaporization chamber and a reservoir intended to receive and store the water before it is injected by various known means such as needles, bushels or pumps in said vaporization chamber for be evaporated there.

TECHNIQUE ANTERIEUREPRIOR TECHNIQUE

Dans les fers à vapeur connus du type précité, le réservoir d'eau est généralement réalisé selon l'une des dispositions suivantes.In known steam irons of the aforementioned type, the water tank is generally produced according to one of the following provisions.

Le réservoir d'eau peut constituer un ensemble autonome. Le fer comporte alors une semelle surmontée d'un corps chauffant dans lequel est ménagée une chambre de vaporisation, un écran thermique disposé au-dessus du corps chauffant, le réservoir d'eau étant alors disposé au-dessus dudit écran. Le réservoir d'eau est dans ce cas le plus souvent réalisé au moyen de deux demi coques assemblées entre elles de façon à former un corps creux. Ce corps creux peut contenir des éléments destinés à des fonctions diverses telles que par exemple conduire l'eau pour alimenter des pompes, ou encore contenir des éléments tels que des résines de traitement de l'eau. Le corps creux est conçu de façon à laisser au moins un orifice de remplissage pour l'eau. De façon avantageuse, ce corps creux est réalisé en polypropylène, les deux demi coques étant assemblées par soudure. The water tank can constitute an autonomous assembly. The iron then comprises a soleplate surmounted by a heating body in which is formed a vaporization chamber, a heat shield placed above the body heating, the water tank then being disposed above said screen. The water tank is in this case most often achieved by means of two half shells assembled together so as to form a hollow body. This hollow body may contain elements intended for various functions such as by example conduct water to supply pumps, or even contain elements such as water treatment resins. The hollow body is designed to so as to leave at least one filling opening for the water. In a way advantageous, this hollow body is made of polypropylene, the two half shells being assembled by welding.

Une telle réalisation présente l'inconvénient d'être relativement coûteuse. Le réservoir étant réalisé de façon indépendante, il faut mouler chacune des pièces le composant, puis les assembler par soudure et enfin contrôler à ce stade la bonne étanchéité de l'ensemble.Such an embodiment has the disadvantage of being relatively expensive. The tank being produced independently, each part must be molded the component, then assemble them by welding and finally check at this stage the good sealing of the assembly.

Une telle réalisation présente également l'inconvénient de multiplier les risques de défaillance par fuite d'eau, que ce soit dès la construction du réservoir, ou après un certain temps d'utilisation. En effet il est difficile d'assurer et de maintenir l'étanchéité entre fond de réservoir polypropylène et chambre de vaporisation du fait de la relative souplesse du polypropylène à des températures proches de sa limite d'utilisation.Such an embodiment also has the disadvantage of multiplying the risks of water leakage failure, either from the construction of the tank, or after a certain time of use. Indeed it is difficult to insure and maintain the seal between the bottom of the polypropylene tank and the vaporization chamber of the made of the relative flexibility of polypropylene at temperatures close to its usage limit.

Le réservoir d'eau peut être aussi obtenu par assemblage d'une demi coque formant partie supérieure de réservoir avec une pièce jouant à la fois le rôle de partie inférieure de réservoir et d'écran thermique.The water tank can also be obtained by assembling a half shell forming the upper part of the tank with a part playing both the role of lower part of tank and heat shield.

Dans ce dernier cas se pose le problème de réaliser cet assemblage de façon durablement étanche et à un coût compétitif par rapport aux autres solutions. L'écran thermique, de par sa fonction, est réalisé de préférence dans un matériau isolant thermique résistant bien à la température tel qu'une résine phénolique ou polyester. La partie supérieure du réservoir étant réalisée le plus souvent en matériau thermoplastique, transparent de préférence, il est alors exclu de réaliser la liaison avec la partie inférieure par soudure. Les solutions connues consistent alors à prévoir une gorge périphérique, généralement dans l'écran thermique, à interposer dans ladite gorge une résine ou un silicone liquide, ou encore des joints solides de type silicone ou caoutchouc, ces derniers pouvant être obtenus par moulage ou extrusion. Le document FR 2 747 404 décrit une telle solution. L'assemblage peut être également complété par une ou plusieurs vis. Aucune de ces solutions ne permet d'obtenir un assemblage simple et économique.In the latter case, the problem arises of making this assembly so durably waterproof and at a competitive cost compared to other solutions. The heat shield, by its function, is preferably made of a material thermal insulation resistant to temperature such as phenolic resin or polyester. The upper part of the tank is most often made of thermoplastic material, preferably transparent, it is therefore excluded to make the connection with the lower part by welding. The known solutions consist then to provide a peripheral groove, generally in the heat shield, to interpose in said groove a resin or a liquid silicone, or else seals solids of silicone or rubber type, the latter being obtainable by molding or extrusion. Document FR 2 747 404 describes such a solution. The assembly can also be completed with one or more screws. None of these solutions only allow a simple and economical assembly.

De même, le document FR2391310 décrit une solution dans laquelle le réservoir d'eau est constitué pour sa partie basse par un écran thermique, et pour sa partie supérieure par une enveloppe incluant la poignée du fer. Les différences de dilatation sont absorbées par un joint logé dans une rainure de l'écran et une forme complémentaire de l'enveloppe ou inversement. Mais le joint n'est pas adhérent aux parois d'une des pièces, et bien qu'il puisse être constitué par un composé de scellement, il est nécessaire de l'installer au moment de l'assemblage, ce qui complique le montage du réservoir. Similarly, the document FR2391310 describes a solution in which the reservoir water is made up for its lower part by a heat shield, and for its part upper by an envelope including the handle of the iron. The differences of expansion are absorbed by a seal housed in a groove of the screen and a complementary shape of the envelope or vice versa. But the joint is not adheres to the walls of one of the parts, and although it may be constituted by a sealing compound, it is necessary to install it when assembly, which complicates the assembly of the tank.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

L'objet de la présente invention est de palier les inconvénients précités et de réaliser l'assemblage d'une partie supérieure de réservoir avec une partie inférieure de réservoir formant écran thermique de façon simple, fiable et économique.The object of the present invention is to overcome the aforementioned drawbacks and to assemble an upper part of the tank with a part tank bottom forming a heat shield in a simple, reliable and economic.

Cet objet est atteint avec un réservoir de fer à repasser comprenant une demi coque inférieure comportant au moins une conformation annulaire et une demi coque supérieure comportant au moins une conformation annulaire prévue pour s'imbriquer dans et/ou par dessus la conformation annulaire correspondante de la demi coque inférieure, caractérisé en ce que au moins l'une des conformations est réalisée avec un revêtement fixé de manière irréversible et faisant office de joint d'étanchéité.This object is reached with an iron tank comprising a half lower shell comprising at least one and a half annular conformation upper shell comprising at least one annular conformation provided for nest in and / or over the corresponding annular conformation of the lower half-shell, characterized in that at least one of the conformations is made with a covering fixed in an irreversible way and acting as a joint sealing.

Le réservoir obtenu présente une grande fiabilité vis à vis de l'étanchéité. Ce résultat est obtenu par le fait que le ou les revêtements faisant office de joint adhèrent sur l'une des demi coques. Cette adhérence présente deux effets qui concourent à la bonne étanchéité de l'ensemble. Tout d'abord, elle élimine les fuites entre le ou les joints et la demi coque à laquelle il est attaché, en particulier celles qui résulteraient d'un défaut des surfaces en contact. Ensuite, elle autorise un serrage maximum transversal sur le ou les joints, l'assemblage pouvant être fait à la presse sous de fortes pressions, la liaison irréversible du joint avec une des pièces permettant d'éviter son glissement et son extrusion.The tank obtained has great reliability with regard to sealing. This result is obtained by the fact that the coating or coatings acting as a seal adhere to one of the half shells. This adhesion has two effects which contribute to the good sealing of the assembly. First, it eliminates leaks between the joint (s) and the half-shell to which it is attached, in particular those which would result from a defect in the surfaces in contact. Then it authorizes maximum transverse tightening on the joint (s), assembly can be done to the press under high pressures, the irreversible connection of the seal with one of the parts to prevent slipping and extrusion.

Cette réalisation permet d'obtenir un ensemble autonome et transportable sans risque, notamment pour la suite du processus de fabrication. Cette caractéristique permet de faciliter le processus d'assemblage du fer à repasser en permettant de différer ou même de supprimer l'assemblage par vis.This achievement makes it possible to obtain an autonomous and transportable assembly without risk, especially for the rest of the manufacturing process. This characteristic facilitates the assembly process of the iron by allowing defer or even remove the screw assembly.

Selon un premier mode de réalisation, la ou l'une des conformations annulaires ménagée sur la demi coque inférieure est une gorge, et la ou l'une des conformations annulaires correspondantes de la demi coque supérieure est une jupe.According to a first embodiment, the or one of the annular conformations formed on the lower half-shell is a groove, and the or one of the corresponding annular conformations of the upper half shell is a skirt.

Selon un deuxième mode de réalisation, la ou l'une des conformations annulaires ménagée sur la demi coque inférieure est une jupe, et la ou l'une des conformations annulaires correspondantes de la demi coque supérieure est une gorge.According to a second embodiment, the or one of the annular conformations formed on the lower half-shell is a skirt, and the or one of the corresponding annular conformations of the upper half shell is a throat.

Selon une première variante de réalisation, le ou l'un des revêtements faisant office de joint d'étanchéité est disposé dans la ou l'une des gorges.According to a first alternative embodiment, the or one of the coatings forming seal office is arranged in the or one of the grooves.

Selon une deuxième variante de réalisation, le ou l'un des revêtements faisant office de joint d'étanchéité est disposé sur la ou l'une des jupes.According to a second alternative embodiment, the or one of the coatings forming seal office is arranged on one or one of the skirts.

Avantageusement, le ou l'un des revêtements faisant office de joint d'étanchéité présente une épaisseur comprise entre 0,5 et 5 mm.Advantageously, the or one of the coatings acting as a seal has a thickness between 0.5 and 5 mm.

Avantageusement le ou l'un des revêtements faisant office de joint d'étanchéité est réalisé en EPDM, abréviation qui désigne un caoutchouc éthylène-propylène-diène.Advantageously the or one of the coatings acting as a seal is made of EPDM, an abbreviation which designates an ethylene-propylene-diene rubber.

Selon une forme de réalisation avantageuse, la demi coque inférieure comporte une première conformation annulaire et une deuxième conformation annulaire adjacente à la première conformation annulaire, et la demi coque supérieure comporte une première conformation annulaire et une deuxième conformation annulaire adjacente à la première conformation annulaire.According to an advantageous embodiment, the lower half-shell comprises a first annular conformation and a second annular conformation adjacent to the first annular conformation, and the upper half-shell has a first annular conformation and a second conformation annular adjacent to the first annular conformation.

Selon une autre forme de réalisation avantageuse, la demi coque inférieure comporte une conformation annulaire périphérique et une conformation annulaire intérieure, et la demi coque supérieure comporte une conformation annulaire périphérique et une conformation annulaire intérieure.According to another advantageous embodiment, the lower half-shell has a peripheral annular conformation and an annular conformation interior, and the upper half-shell has an annular conformation peripheral and an inner annular conformation.

L'invention concerne également un procédé de réalisation d'un réservoir de fer à repasser dans lequel le ou l'un des revêtements faisant office de joint d'étanchéité est obtenu par surmoulage sur la ou l'une des conformations annulaires.The invention also relates to a method for producing an iron reservoir iron in which the or one of the coatings acting as a seal is obtained by overmolding on the or one of the annular conformations.

Cette réalisation permet d'obtenir une qualité d'assemblage optimale sans nécessiter d'investissements importants tels que celui d'une presse bi-injection, même si le surmoulage du joint demande une opération de reprise.This achievement provides optimal assembly quality without require significant investments such as that of a bi-injection press, even if the overmolding of the joint requires a recovery operation.

L'invention conceme également un procédé de réalisation d'un réservoir de fer à repasser dans lequel le ou l'un des revêtements faisant office de joint d'étanchéité est obtenu avec l'une des demi coques par moulage bi-injection.The invention also relates to a method for producing an iron reservoir iron in which the or one of the coatings acting as a seal is obtained with one of the half shells by bi-injection molding.

Cette solution optimise les coûts de fabrication puisque l'une des demi coques et le ou les revêtements faisant office de joint d'étanchéité sont obtenus en une seule opération d'injection.This solution optimizes manufacturing costs since one of the half shells and the coating or coatings acting as a seal are obtained in a single injection operation.

Avantageusement la ou l'une des conformations opposée à celle réalisée avec le ou l'un des revêtements faisant office de joint d'étanchéité présente au moins un canal d'évent.Advantageously the or one of the conformations opposite to that produced with the or one of the coatings acting as a seal has at least one vent channel.

En effet lorsque l'on exerce la pression d'emmanchage sur l'une des demi coques pour mettre en place le joint dans la conformation annulaire de la demi coque opposée, on emprisonne et on comprime entre le joint et la conformation annulaire de l'air. Or l'installation dès le début de la vie de l'assemblage d'une pression antagoniste à la direction dans laquelle on veut au contraire maintenir les demi coques est préjudiciable. La pression existant à température ambiante ira en augmentant lorsque l'air emprisonné entre le joint et la demi coque inférieure s'échauffera lors de l'utilisation du fer à repasser. A titre d'exemple on a calculé qu'un effort supérieur à 1000 N pouvait être appliqué vers le haut sur la demi coque supérieure.In fact when one exerts the fitting pressure on one of the half shells to set up the seal in the annular conformation of the half shell opposite, we trap and compress between the joint and the annular conformation air. However, the installation from the start of the assembly life of a pressure antagonistic to the direction in which we want on the contrary to maintain the half cockles is detrimental. The pressure existing at room temperature will go increasing when the air trapped between the joint and the lower half-shell will heat up when using the iron. As an example we calculated that a force greater than 1000 N could be applied upwards on the half upper shell.

Un canal d'évent permet d'éviter l'installation d'une pression antagoniste à l'intérieur de l'assemblage, préjudiciable pour un dispositif devant travailler en température. Il n'est plus nécessaire de mouler sans dépouille la conformation annulaire de la demi coque opposée à celle portant le revêtement pour éviter des efforts d'emmanchement relativement importants risquant de détruire partiellement les demi coques. Cet avantage est intéressant car le moulage sans dépouille complique et renchérit les opérations de moulage. Il n'est pas nécessaire non plus de surdimensionner les conformations annulaires pour que celles-ci puissent résister aux efforts exercés. L'assemblage obtenu est moins coûteux, plus résistant et plus durable.A vent channel avoids the installation of a counter pressure to inside the assembly, detrimental for a device having to work in temperature. It is no longer necessary to mold without shaping the conformation annular of the half shell opposite to that carrying the coating to avoid relatively large fitting efforts that may partially destroy the half shells. This advantage is interesting because the molding without skin complicates and increases the molding operations. There is no need either to oversize the annular conformations so that they can resist the efforts exerted. The assembly obtained is less expensive, more resistant and more durable.

L'invention concerne également un procédé de réalisation d'un réservoir de fer à repasser dans lequel on vient obturer le ou l'un des canaux d'évent après assemblage de la demi coque supérieure sur la demi coque inférieure.The invention also relates to a method for producing an iron reservoir iron in which one comes to close off the or one of the vent channels after assembly of the upper half shell on the lower half shell.

Une telle réalisation permet de bénéficier d'une plus grande liberté dans l'implantation des canaux d'évent, formant des passages libres pour l'évacuation de l'air lors de l'opération d'assemblage. En particulier, les canaux d'évent peuvent déboucher dans la zone du réservoir prévue pour recevoir l'eau. Leur obturation permet d'éviter les inconvénients liés à la présence d'eau sous le joint.Such an achievement allows for greater freedom in the installation of vent channels, forming free passages for evacuation air during the assembly operation. In particular, the vent channels can lead into the area of the reservoir intended to receive the water. Their shutter avoids the drawbacks linked to the presence of water under the joint.

L'invention concerne également un procédé de réalisation d'un réservoir de fer à repasser consistant à réaliser l'opération d'assemblage de la demi coque inférieure avec la demi coque supérieure sous vide partiel.The invention also relates to a method for producing an iron reservoir ironing consisting in carrying out the assembly operation of the half shell lower with the upper half shell under partial vacuum.

Un tel procédé permet d'obtenir un assemblage moins coûteux, plus résistant et plus durable, l'air raréfié ne créant pas d'efforts importants sur les conformations lors de l'emmanchement de la demi coque supérieure dans la demi coque inférieure.Such a method makes it possible to obtain a less expensive, more resistant and more durable, rarefied air does not create significant efforts on conformations during the fitting of the upper half-shell into the half-shell lower.

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST WAY TO IMPLEMENT THE INVENTION

Le réservoir de fer à repasser selon l'invention comprend une demi coque inférieure comportant au moins une conformation annulaire. Selon les exemples de réalisation montrés aux figures 1 et 4, la demi coque inférieure 1; 11 comporte deux conformations annulaires 3, 13 ; 23, 33, formées chacune par une gorge.The iron tank according to the invention comprises a half shell lower comprising at least one annular conformation. According to the examples shown in Figures 1 and 4, the lower half shell 1; 11 features two annular conformations 3, 13; 23, 33, each formed by a groove.

Le réservoir de fer à repasser selon l'invention comprend également une demi coque supérieure comportant au moins une conformation annulaire, dite conformation annulaire associée, prévue pour s'imbriquer dans et/ou par dessus la conformation annulaire correspondante de la demi coque inférieure. Selon les exemples de réalisation montrés aux figures 2 et 5, la demi coque supérieure 2 ; 12 comporte deux conformations annulaires 4, 14 ; 24, 34, formées chacune par une jupe.The iron tank according to the invention also comprises a half upper shell comprising at least one annular conformation, called associated annular conformation, designed to nest in and / or over the corresponding annular conformation of the lower half-shell. According to exemplary embodiments shown in Figures 2 and 5, the upper half shell 2; 12 has two annular conformations 4, 14; 24, 34, each formed by a skirt.

A titre de variante, non montrée aux figures, l'une des conformations annulaires ménagées sur la demi coque inférieure est une jupe, et la conformation annulaire correspondante de la demi coque supérieure est une gorge.Alternatively, not shown in the figures, one of the annular conformations formed on the lower half-shell is a skirt, and the annular conformation corresponding to the upper half shell is a groove.

De préférence le réservoir comporte deux conformations annulaires 3, 13 ; 23, 33 ; 4, 14 ; 24, 34 sur chacune des demi coques 1 ; 11 ; 2 ; 12, tel que montré aux figures. Cette disposition permet de ménager des passages 7 ; 17 dans la demi coque supérieure 2 ; 12 et des passages 8 ; 18 dans la demi coque inférieure 1 ; 11, pour des commandes de thermostat par exemple.Preferably the reservoir has two annular conformations 3, 13; 23, 33; 4, 14; 24, 34 on each of the half shells 1; 11; 2; 12, as shown in FIGS. This arrangement makes it possible to provide passages 7; 17 in the half upper shell 2; 12 and passages 8; 18 in the lower half-shell 1; 11, for thermostat controls for example.

Les figures 1, 2 et 3 montrent une première forme de réalisation, dite adjacente, dans laquelle la demi coque inférieure 1 et la demi coque supérieure 2 comportent chacune une première conformation annulaire 3 ; 4 et une deuxième conformation annulaire 13 ; 14 adjacente à la première conformation annulaire 3 ; 4. FIGS. 1, 2 and 3 show a first embodiment, known as adjacent, in which the lower half-shell 1 and the upper half-shell 2 comprise each a first annular conformation 3; 4 and a second conformation annular 13; 14 adjacent to the first annular conformation 3; 4.

Tel que montré à la figure 1, la conformation annulaire 3 de la demi coque inférieure 1 délimite une cavité 9 formant réservoir, ladite cavité comportant un orifice 6 prévu pour le passage d'un pointeau (non représenté aux figures) destiné à l'alimentation de la chambre de vaporisation d'un fer. La demi coque supérieure 2 montrée à la figure 2 comporte également un orifice 10 prévu pour le passage du pointeau.As shown in Figure 1, the annular conformation 3 of the half shell lower 1 defines a cavity 9 forming a reservoir, said cavity comprising a orifice 6 provided for the passage of a needle (not shown in the figures) intended to the steam chamber of an iron. The upper half shell 2 shown in FIG. 2 also includes an orifice 10 provided for the passage of the needle.

Les figures 4, 5 et 6 montrent une deuxième forme de réalisation, dite concentrique, dans laquelle la demi coque inférieure 11 et la demi coque supérieure 12 comportent chacune une conformation annulaire périphérique 23 ; 24 et une conformation annulaire intérieure 33 ; 34.Figures 4, 5 and 6 show a second embodiment, called concentric, in which the lower half-shell 11 and the half-shell upper 12 each have a peripheral annular conformation 23; 24 and an inner annular conformation 33; 34.

Tel que montré à la figure 4, la conformation annulaire périphérique 23 et la conformation annulaire intérieure 33 de la demi coque inférieure 11 délimitent une cavité 29 formant réservoir, ladite cavité comportant un orifice 16 prévu pour le passage d'un pointeau (non représenté aux figures) destiné à l'alimentation de la chambre de vaporisation d'un fer. La demi coque supérieure 12 comporte également un orifice 19 prévu pour le passage du pointeau.As shown in FIG. 4, the peripheral annular conformation 23 and the inner annular conformation 33 of the lower half-shell 11 delimit a cavity 29 forming a reservoir, said cavity comprising an orifice 16 provided for the passage of a needle (not shown in the figures) intended for supplying the steam chamber of an iron. The upper half-shell 12 comprises also an orifice 19 provided for the passage of the needle.

A titre de variante, il est envisageable de réaliser un réservoir dont chacune des demi coques ne comporte qu'une conformation annulaire, ou au contraire, plus de deux conformations annulaires.As a variant, it is conceivable to produce a reservoir, each of the half shells only have an annular conformation, or on the contrary, more than two annular conformations.

Selon l'invention au moins l'une des conformations est réalisée avec un revêtement faisant office de joint d'étanchéité.According to the invention at least one of the conformations is produced with a coating acting as a seal.

Avantageusement selon la forme de réalisation dite adjacente, dont un exemple de réalisation est montré aux figures 1 à 3 un premier revêtement faisant office de joint d'étanchéité 5 est disposé sur la première conformation annulaire 4 de la demi coque supérieure 2, et un deuxième revêtement faisant office de joint d'étanchéité 15 est disposé sur la deuxième conformation annulaire 14 de la demi coque supérieure 2. A titre de variante lorsque l'une des conformations annulaires de la demi coque supérieure 2 est une gorge et non une jupe le revêtement correspondant est disposé dans ladite gorge.Advantageously according to the so-called adjacent embodiment, including an example of embodiment is shown in Figures 1 to 3 a first coating acting as seal 5 is disposed on the first annular conformation 4 of the upper half-shell 2, and a second covering acting as a seal seal 15 is arranged on the second annular conformation 14 of the half upper shell 2. As a variant when one of the annular conformations of the upper half shell 2 is a groove and not a skirt the covering corresponding is disposed in said groove.

Avantageusement selon la forme de réalisation dite concentrique, dont un exemple de réalisation est montré aux figures 4 à 6 un revêtement faisant office de joint d'étanchéité 25 est disposé sur la conformation annulaire périphérique 24 de la demi coque supérieure 12, et un autre revêtement faisant office de joint d'étanchéité 35 est disposé sur la conformation annulaire intérieure 34 de la demi coque supérieure 12. A titre de variante lorsque l'une des conformations annulaires de la demi coque supérieure 12 est une gorge et non une jupe le revêtement correspondant est disposé dans ladite gorge.Advantageously according to the so-called concentric embodiment, an example of which embodiment is shown in Figures 4 to 6 a coating acting as a seal seal 25 is disposed on the peripheral annular conformation 24 of the upper half-shell 12, and another covering acting as a seal seal 35 is arranged on the inner annular conformation 34 of the half upper shell 12. As a variant when one of the conformations annular of the upper half-shell 12 is a groove and not a skirt the corresponding coating is arranged in said groove.

Tel que montré aux figures 2 et 3, les jupes formant les conformations annulaires 4, 14 de la demi coque supérieure 2 sont réalisées avec un revêtement faisant office de joint d'étanchéité 5, 15. Tel que montré aux figures 5 et 6, les jupes formant les conformations annulaires 24, 34 de la demi coque supérieure 12 sont réalisées avec un revêtement faisant office de joint d'étanchéité 25, 35.As shown in Figures 2 and 3, the skirts forming the annular conformations 4, 14 of the upper half-shell 2 are produced with a coating making seal office 5, 15. As shown in Figures 5 and 6, the skirts forming the annular conformations 24, 34 of the upper half-shell 12 are made with a coating serving as a seal 25, 35.

Plus particulièrement, selon les formes de réalisation montrées aux figures 3 et 6, chaque joint 5, 15 ; 25, 35 est fixé sur l'extrémité de chaque conformation annulaire associée formée par l'une des jupes 4, 14 ; 24, 34. Chaque joint 5, 15; 25, 35 est susceptible de coopérer par serrage avec la conformation annulaire correspondante formée par l'une des gorges 3, 13 ; 23, 33.More particularly, according to the embodiments shown in FIGS. 3 and 6, each joint 5, 15; 25, 35 is fixed on the end of each conformation associated annular formed by one of the skirts 4, 14; 24, 34. Each joint 5, 15; 25, 35 is capable of cooperating by tightening with the annular conformation corresponding formed by one of the grooves 3, 13; 23, 33.

A titre de variante, non montrée aux figures, au moins l'un des revêtements faisant office de joint d'étanchéité est disposé dans l'une des gorges. Ladite gorge peut appartenir à l'une des conformations annulaires de la demi coque supérieure comme de la demi coque inférieure.As a variant, not shown in the figures, at least one of the coatings forming seal office is arranged in one of the grooves. Said throat can belong to one of the annular conformations of the upper half-shell like the lower half shell.

Avantageusement l'un des revêtements faisant office de joint d'étanchéité 5, 15; 25, 35 présente une épaisseur comprise entre 0,5 et 5 mm. De préférence tous lesdits revêtements présentent ces caractéristiques.Advantageously one of the coatings acting as a seal 5, 15; 25, 35 has a thickness of between 0.5 and 5 mm. Preferably all said coatings have these characteristics.

Avantageusement l'un des revêtements faisant office de joint d'étanchéité 5, 15; 25, 35 est réalisé en EPDM. D'autres matières, telles que les silicones ou les caoutchoucs néoprène, sont possibles, et d'une manière plus générale toute matière susceptible de supporter des températures de l'ordre de 100 °C à 150°C en conservant des caractéristiques élastiques et une compressibilité importante.Advantageously one of the coatings acting as a seal 5, 15; 25, 35 is made of EPDM. Other materials, such as silicones or neoprene rubbers are possible, and more generally any material capable of withstanding temperatures of the order of 100 ° C to 150 ° C retaining elastic characteristics and high compressibility.

La demi coque inférieure 1 ; 11 est réalisée de préférence en une matière résistant à des températures d'au moins 200°C, telle qu'une résine. Un tel matériau présente de plus l'avantage de n'être pas un très bon conducteur de chaleur. La demi coque supérieure 2 ; 12 est de préférence réalisée en matériau thermoplastique, transparent de préférence.The lower half shell 1; 11 is preferably made of a resistant material at temperatures of at least 200 ° C, such as a resin. Such a material also has the advantage of not being a very good conductor of heat. The upper half shell 2; 12 is preferably made of material thermoplastic, preferably transparent.

Chaque conformation annulaire associée de la demi coque supérieure est susceptible de coopérer avec la conformation annulaire correspondante ménagée dans la demi coque inférieure. Plus particulièrement, selon les exemples de réalisation montrés aux figures, chaque jupe 4, 14 ; 24, 34 est prévue pour être insérée dans la gorge 3, 13 ; 23, 33 correspondante.Each associated annular conformation of the upper half-shell is capable of cooperating with the corresponding annular conformation formed in the lower half shell. More particularly, according to the examples of embodiment shown in the figures, each skirt 4, 14; 24, 34 is scheduled to be inserted into the groove 3, 13; 23, 33 corresponding.

Les dimensions relatives de chaque conformation annulaire associée telle que l'une des jupes 4, 14 ; 24, 34, chaque joint 5, 15 ; 25, 35 et chaque conformation annulaire correspondante telle que l'une des gorges 3, 13 ; 23, 33 sont prévues pour obtenir une pression relative selon une direction sensiblement perpendiculaire à la direction d'assemblage. Cette pression latérale peut être d'autant plus importante que l'on est capable de réaliser l'assemblage de la partie supérieure avec son joint sur la partie inférieure avec une force importante et ce sans risquer que le joint ne se déplace pendant cette opération. Dans la mesure où une compression de 10% à 30% des joints 5, 15 ; 25, 35 dans le sens latéral est recherchée chaque gorge 3, 13 ; 23; 33 peut avoir une largeur de 3 à 10 mm et chacune des parois du joint entre jupe et gorge une épaisseur de 0,5 à 5 mm.The relative dimensions of each associated annular conformation such as one of the skirts 4, 14; 24, 34, each seal 5, 15; 25, 35 and each conformation corresponding annular such as one of the grooves 3, 13; 23, 33 are planned to obtain a relative pressure in a direction substantially perpendicular to the direction of assembly. This lateral pressure can be all the more important as we are able to assemble the part upper with its seal on the lower part with significant force and this without risking that the seal will move during this operation. Insofar where a compression of 10% to 30% of the joints 5, 15; 25, 35 sideways is sought each groove 3, 13; 23; 33 can have a width of 3 to 10 mm and each of the walls of the joint between skirt and groove a thickness of 0.5 to 5 mm.

Avantageusement la demi coque inférieure 1 ; 11 et la demi coque supérieure 2 ; 12 comportent des moyens de fixation complémentaires. Tel que montré aux figures 1, 2, 4 et 5, la demi coque supérieure 2 ; 12 comporte des pattes 41 ; 51 comportant chacune un orifice 42 ; 52 susceptible de venir en regard de logements 43 ; 53 ménagés dans la demi coque inférieure 1 ; 11. Les orifices 42 ; 52 et les logements 43 ; 53 sont prévus pour un assemblage par vis. Un nombre différent de pattes 41 ; 51 ou un autre mode d'assemblage sont également envisageables.Advantageously the lower half-shell 1; 11 and the upper half-shell 2; 12 comprise complementary fixing means. As shown to Figures 1, 2, 4 and 5, the upper half shell 2; 12 has tabs 41; 51 each having an orifice 42; 52 likely to come next to housing 43; 53 formed in the lower half-shell 1; 11. The orifices 42; 52 and the housing 43; 53 are provided for assembly by screws. A different number legs 41; 51 or another method of assembly are also possible.

L'invention concerne également un procédé de réalisation d'un réservoir de fer à repasser comprenant lesdites demi coques inférieure 1 ; 11 et supérieure 2 ; 12.The invention also relates to a method for producing an iron reservoir ironing comprising said lower half shells 1; 11 and above 2; 12.

Le procédé selon l'invention consiste à réaliser un revêtement faisant office de joint d'étanchéité sur l'une des conformations annulaires avant d'assembler la demi coque inférieure 1 ; 11 avec la demi coque supérieure 2 ; 12. Ceci revient à fixer de manière irréversible un joint sur ladite conformation.The method according to the invention consists in producing a coating acting as seal on one of the annular conformations before assembling the lower half shell 1; 11 with the upper half-shell 2; 12. This comes down to irreversibly fix a joint on said conformation.

La figure 7 montre la demi coque inférieure 11 et la demi coque supérieure 12 avant assemblage. La figure 8 montre la demi coque inférieure 11 et la demi coque supérieure 12 après assemblage.Figure 7 shows the lower half shell 11 and the upper half shell 12 before assembly. Figure 8 shows the lower half shell 11 and the half upper shell 12 after assembly.

Selon l'exemple de réalisation montré aux figures 7 et 8 le procédé consiste à fixer de manière irréversible un joint 25, 35 sur chaque jupe 24, 34 avant d'assembler la demi coque inférieure 11 avec la demi coque supérieure 12 en insérant chaque joint 25, 35 dans la gorge 23, 33 correspondante.According to the example of embodiment shown in FIGS. 7 and 8, the method consists in fixing irreversibly a joint 25, 35 on each skirt 24, 34 before assembling the lower half shell 11 with upper half shell 12 inserting each seal 25, 35 in the corresponding groove 23, 33.

Avantageusement selon un premier mode de réalisation dudit procédé l'un des revêtements faisant office de joint d'étanchéité est obtenu par surmoulage sur ou dans l'une des conformations annulaires. De préférence chacun des revêtements faisant office de joint d'étanchéité est obtenu par surmoulage sur ou dans l'une des conformations annulaires. Par exemple tel que représenté sur les figures 1 à 6 chaque joint 5, 15 ; 25, 35 est obtenu par surmoulage sur la conformation annulaire associée 4, 14 ; 24, 34 de la demi coque supérieure 2 ; 12.Advantageously according to a first embodiment of said method one of the coatings acting as a seal is obtained by overmolding on or in one of the annular conformations. Preferably each of the coatings acting as a seal is obtained by overmolding on or in one annular conformations. For example as shown in Figures 1 to 6 each joint 5, 15; 25, 35 is obtained by overmolding on the conformation associated annular 4, 14; 24, 34 of the upper half-shell 2; 12.

Avantageusement encore selon un deuxième mode de réalisation dudit procédé l'un des revêtements faisant office de joint d'étanchéité est obtenu avec l'une des demi coques par moulage bi-injection. De préférence chacun des revêtements faisant office de joint d'étanchéité est obtenu avec l'une des demi coques par moulage bi-injection. Par exemple tel que représenté sur les figures 1 à 6 chaque joint 5, 15 ; 25, 35 est obtenu avec la demi coque supérieure 2 ; 12 par moulage bi-injection.Advantageously also according to a second embodiment of said method one of the coatings acting as a seal is obtained with one of the half shells by bi-injection molding. Preferably each of the coatings acting as a seal is obtained with one of the half shells by bi-injection molding. For example as shown in Figures 1 to 6 each seal 5, 15; 25, 35 is obtained with the upper half-shell 2; 12 by molding bi-injection.

Il est également envisageable d'obtenir un ou des joints par moulage bi-injection, et un autre ou d'autres joints par sur moulage.It is also possible to obtain one or more seals by bi-injection molding, and another or other seals by over molding.

Il est encore possible d'obtenir au moins un joint par moulage ou extrusion classique, et de le coller ou de l'assembler de façon définitive à l'une des demi coques du réservoir.It is still possible to obtain at least one joint by molding or extrusion classic, and to glue it or assemble it definitively to one of the half tank hulls.

Il est encore possible d'obtenir un ou des joints par moulage bi-injection et/ou par sur moulage, et un autre ou des autres joints par moulage ou extrusion classique, ces demiers joints étant ensuite collés ou assemblés, par exemple à la demi coque supérieure du réservoir.It is also possible to obtain one or more seals by bi-injection molding and / or by on molding, and another or other joints by conventional molding or extrusion, these last joints then being glued or assembled, for example half upper shell of the tank.

Le réservoir montré aux figures 7 et 8 présente également de manière connue un orifice de remplissage 20 ménagé dans la demi coque supérieure 12, ainsi que des orifices 16, 19 ménagés respectivement dans les demi coques inférieure 11 et supérieure 12, prévus pour recevoir un dispositif d'injection d'eau dans la chambre de vaporisation (non représentés aux figures).The reservoir shown in Figures 7 and 8 also has in known manner a filling orifice 20 formed in the upper half-shell 12, as well as orifices 16, 19 formed respectively in the lower half-shells 11 and upper 12, designed to receive a device for injecting water into the chamber vaporization (not shown in the figures).

Dans le mode de réalisation montré aux figures 7 et 8 une chambre 29 destinée à recevoir le liquide est délimitée par les conformations annulaires 23, 33. Ces conformations sous forme de gorge comportent un premier rebord 23', 33', disposé du coté de la chambre 29 et un second rebord 23", 33", disposé du côté opposé à la chambre 29. Les joints 25 ; 35 lors de l'opération d'assemblage sont montés en compression entre les rebords 23', 23" ; 33', 33". Cette disposition permet d'obtenir un maintien ferme des deux demi coques après assemblage.In the embodiment shown in Figures 7 and 8 a chamber 29 for receiving the liquid is delimited by the annular conformations 23, 33. These groove-shaped conformations have a first rim 23 ', 33', arranged on the side of the chamber 29 and a second flange 23 ", 33", arranged on the side opposite the chamber 29. The seals 25; 35 during the assembly operation are mounted in compression between the flanges 23 ', 23 "; 33', 33". This provision provides firm support for the two half shells after assembly.

Avantageusement l'une des conformations opposée à celle réalisée avec l'un des revêtements faisant office de joint d'étanchéité présente au moins un canal d'évent. Ainsi la demi coque inférieure et /ou la demi coque supérieure comporte des moyens pour éviter que de l'air ne reste comprimé sous le ou les joints après l'opération d'assemblage des deux demi coques . Advantageously one of the conformations opposite to that produced with one of the coverings acting as a seal has at least one channel Wind. Thus the lower half shell and / or the upper half shell comprises means to prevent air from remaining compressed under the joint (s) after the assembly operation of the two half shells.

La figure 9 montre un détail d'un premier exemple de réalisation des moyens précités. Le joint 25 monté sur la conformation annulaire associée 24 est maintenu en compression par le premier rebord 23' et le second rebord 23" de la gorge 23. Un espace 61 est obtenu entre le joint 25 inséré dans la gorge 23 et le fond de ladite gorge. Un canal d'évent 62 formé par un orifice ménagé dans le fond de la gorge 23 et traversant la demi coque 11 permet de mettre en communication l'espace 61 avec l'extérieur. Cette disposition permet d'éviter que de l'air ne reste comprimé sous le joint 25. Le canal d'évent 62 ne perturbe pas l'étanchéité du réservoir puisqu'il est isolé de l'intérieur de celui ci par la paroi du joint. Avantageusement plusieurs canaux 62 sont prévus pour mettre en communication l'espace 61 avec l'extérieur. Deux à quatre canaux 62 par gorge 23 sont un bon ordre de grandeur.Figure 9 shows a detail of a first embodiment of the means supra. The seal 25 mounted on the associated annular conformation 24 is maintained in compression by the first edge 23 'and the second edge 23 "of the groove 23. A space 61 is obtained between the seal 25 inserted in the groove 23 and the bottom of said throat. A vent channel 62 formed by an orifice made in the bottom of the groove 23 and passing through the half-shell 11 allows communication space 61 with the outside. This arrangement prevents air from remaining compressed under the seal 25. The vent channel 62 does not disturb the tightness of the tank since it is isolated from the inside thereof by the wall of the seal. Advantageously, several channels 62 are provided for communicating space 61 with the outside. Two to four channels 62 per groove 23 are a good magnitude.

Les figures 10a et 10b montrent un détail d'un deuxième exemple de réalisation des moyens précités. Le joint 25 monté sur la conformation annulaire associée 24 est maintenu en compression par le premier rebord 23' et le second rebord 23" de la gorge 23. L'espace 61 obtenu entre le joint 25 inséré dans la gorge 23 et le fond de ladite conformation est mis en communication avec l'extérieur par un canal d'évent latéral 63 ménagé dans la paroi intérieure du rebord 23" formant l'une des parois verticales de la gorge 23. Cette solution présente l'avantage de reporter une fuite éventuelle vers le haut du fer, dans une zone moins critique que dans le cas précédent.Figures 10a and 10b show a detail of a second embodiment of the aforementioned means. The seal 25 mounted on the associated annular conformation 24 is kept in compression by the first rim 23 'and the second rim 23 "of the groove 23. The space 61 obtained between the seal 25 inserted in the groove 23 and the bottom of said conformation is put into communication with the outside by a channel side vent 63 formed in the inner wall of the flange 23 "forming one of the vertical walls of the groove 23. This solution has the advantage of postponing a possible leakage towards the top of the iron, in a less critical zone than in the case previous.

De préférence les canaux d'évents 62 ; 63 ne débouchent pas dans une paroi prévue pour former une partie d'une cavité destinée à contenir de l'eau ou de la vapeur, telle que la chambre 29.Preferably the vent channels 62; 63 do not open into a wall designed to form part of a cavity intended to contain water or steam, such as chamber 29.

Les exemples de réalisation précédents s'appliquent bien entendu à toute gorge formant une conformation annulaire ménagée dans l'une des demi coques. Il est également possible d'envisager un canal d'évent latéral sur la paroi d'une jupe, ou un canal d'évent ménagé dans la paroi de ladite jupe et débouchant au sommet de ladite jupe. The previous embodiments of course apply to any groove forming an annular conformation formed in one of the half shells. It is also possible to envisage a side vent channel on the wall of a skirt, or a vent channel formed in the wall of said skirt and opening at the top of said skirt.

Les moyens prévus pour éviter que de l'air ne reste comprimé sous le ou les joints 5, 15 ; 25, 35 après l'opération d'assemblage peuvent comporter un bouchage d'ouvertures des canaux d'évent 62 ; 63.The means provided to prevent air from remaining compressed under the joint (s) 5, 15; 25, 35 after the assembly operation may include a plugging openings of the vent channels 62; 63.

La figure 11 montre la réalisation présentée à la figure 9 complétée par l'obturation du canal d'évent 62 au moyen d'un apport de silicone 64. La figure 12 montre la réalisation présentée à la figure 10a complétée par l'obturation du canal 63 au moyen d'un apport de silicone 65. Une telle obturation permet d'obtenir plus de latitude pour le choix de l'emplacement du canal 62 ou du canal 63, l'espace 61 étant fermé et ne pouvant pas être envahi par de l'eau ou de la vapeur.Figure 11 shows the embodiment shown in Figure 9 supplemented by the obturation of the vent channel 62 by means of a supply of silicone 64. FIG. 12 shows the realization presented in figure 10a supplemented by the obturation of the channel 63 at by means of a supply of silicone 65. Such a filling makes it possible to obtain more latitude for the choice of the location of channel 62 or channel 63, space 61 being closed and not able to be invaded by water or steam.

Ainsi l'invention conceme également un procédé de réalisation d'un réservoir de fer à repasser dans lequel l'on vient obturer au moins un des canaux d'évents après assemblage de la demi coque supérieure 12 sur la demi coque inférieure 11.Thus, the invention also relates to a method for producing a reservoir for iron in which at least one of the vent channels is closed after assembly of the upper half-shell 12 on the lower half-shell 11.

Le bouchage de l'orifice peut être également obtenu lors de l'opération d'assemblage grâce à une protubérance ménagée sur le joint. Tel que montré à la figure 13, le joint 25 comporte une excroissance 66 prévue pour obturer le canal 62 lors de l'assemblage de la gorge 23 avec la jupe 24. Tel que montré à la figure 14, le joint 25 comporte une excroissance latérale 67 prévue pour obturer le canal 63 lors de l'assemblage de la gorge 23 avec la jupe 24. Une telle obturation permet d'évacuer une grande partie de l'air présent dans l'espace 61 entre le joint 25 et la gorge 23 lors de l'opération d'assemblage et d'éviter l'existence d'une surpression dans ledit espace. Elle présente en outre l'avantage de ne pas demander d'opération supplémentaire.The orifice can also be blocked during the operation assembly thanks to a protrusion formed on the joint. As shown in the Figure 13, the seal 25 has a protrusion 66 provided to close the channel 62 during assembly of the groove 23 with the skirt 24. As shown in the figure 14, the seal 25 has a lateral protuberance 67 provided for closing the channel 63 during assembly of the groove 23 with the skirt 24. Such a closure allows to evacuate a large part of the air present in the space 61 between the joint 25 and the groove 23 during the assembly operation and to avoid the existence of a overpressure in said space. It also has the advantage of not request additional operation.

Ainsi la présente invention concerne également un procédé de réalisation d'un réservoir de fer à repasser consistant à réaliser l'opération d'assemblage de la demi coque inférieure avec la demi coque supérieure sous vide partiel.Thus the present invention also relates to a method of producing a iron tank consisting in carrying out the assembly operation of the lower half-shell with the upper half-shell under partial vacuum.

La figure 15 montre un schéma d'un dispositif prévu pour l'assemblage sous vide de la demi coque supérieure 12 sur la demi coque inférieure 11, dans lequel seule la conformation annulaire 23 et la conformation annulaire associée 24 comportant le joint 25 sont représentées. Une cloche à vide 76 est appliquée sur un plateau 77 sur lequel est disposé la demi coque inférieure 11. Après mise sous vide partiel de la cloche à vide, un vérin 60 vient assembler les deux demi coques 11, 12. De préférence le réservoir ainsi obtenu est remis sous pression atmosphérique avant de libérer l'effort du vérin 60 pour utiliser immédiatement l'effet de la pression atmosphérique sur l'assemblage des deux demi coques. A titre de variante la demi coque supérieure peut être disposée sur un plateau présentant une forme appropriée et la demi coque inférieure assemblée par le vérin sur la demi coque supérieure.Figure 15 shows a diagram of a device intended for vacuum assembly of the upper half-shell 12 on the lower half-shell 11, in which only the annular conformation 23 and the associated annular conformation 24 comprising the seal 25 are shown. A vacuum chamber 76 is applied to a tray 77 on which the lower half-shell is disposed 11. After partial vacuum of the vacuum bell, a jack 60 comes to assemble the two half-shells 11, 12. Of preferably the tank thus obtained is returned to atmospheric pressure before to release the force of the jack 60 to immediately use the effect of the pressure atmospheric on the assembly of the two half shells. As a variant the half upper shell can be arranged on a tray having a shape appropriate and the lower half-shell assembled by the jack on the half-shell higher.

Un autre procédé selon la présente invention consiste à mettre en communication avec l'extérieur tout espace situé entre un joint et une conformation annulaire. Cette opération permet de réaliser une décompression du ou des espaces situés entre chaque joint et chaque conformation annulaire.Another method according to the present invention consists in putting in communication with the exterior any space between a joint and an annular conformation. This operation makes it possible to decompress the space or spaces located between each joint and each annular conformation.

Cet autre procédé peut consister par exemple à utiliser une demi coque inférieure 11 et une demi coque supérieure 12 susceptibles de ménager au moins un passage libre 62, 63 entre chaque joint 25 et chaque conformation annulaire 23, telles que montrées aux figures 9, 10a et 10b.This other process can consist, for example, of using a lower half-shell 11 and an upper half-shell 12 capable of providing at least one free passage 62, 63 between each joint 25 and each annular conformation 23, as shown in Figures 9, 10a and 10b.

Une variante, non montrée aux figures, consiste à créer ledit passage libre, par exemple par perçage de la demi coque inférieure pour mettre en communication avec l'extérieur l'espace situé entre le joint et la conformation annulaire, après l'opération d'assemblage.A variant, not shown in the figures, consists in creating said free passage, by example by drilling the lower half-shell to put in communication with the outside the space between the seal and the annular conformation, after the assembly operation.

Une autre variante, non montrée aux figures, consiste à ménager le canal 63 destiné à former un passage libre sur le joint 25 et non sur la conformation 23.Another variant, not shown in the figures, consists in providing the channel 63 intended to form a free passage on the joint 25 and not on the conformation 23.

Dans le cas ou le réservoir comporte plusieurs joints ainsi assemblés, il est envisageable d'utiliser différentes variantes pour ménager un passage libre entre chaque joint et chaque conformation annulaire correspondante.In the case where the tank has several seals thus assembled, it is possible to use different variants to provide a free passage between each joint and each corresponding annular conformation.

Un tel procédé peut également comporter la réalisation de l'opération d'assemblage de la demi coque inférieure avec la demi coque supérieure sous vide partiel.Such a method may also include carrying out the operation assembly of the lower half shell with the upper half shell under partial vacuum.

Un tel procédé peut également comporter une étape consistant à obturer le ou les passages libres 62, 63 après l'opération d'assemblage. Ainsi la pression existant à température ambiante dans l'espace situé entre chaque joint 25 et chaque conformation annulaire 23 correspondante est de l'ordre de grandeur de la pression atmosphérique, voire inférieure si l'obturation 64, 65, 66, 67 du ou des passages libres 62, 63 est réalisée sous vide partiel.Such a method can also include a step consisting in sealing off the free passages 62, 63 after the assembly operation. Thus the pressure existing at ambient temperature in the space between each joint 25 and each corresponding annular conformation 23 is of the order of magnitude of the atmospheric pressure, or even lower if obturation 64, 65, 66, 67 of the free passages 62, 63 is carried out under partial vacuum.

L'invention n'est nullement limitée strictement aux exemples de réalisation décrits précédemment, mais englobe de nombreuses modifications ou améliorations.The invention is in no way strictly limited to the embodiments described previously, but includes many modifications or improvements.

Notamment il est envisageable de n'utiliser qu'un seul joint, par exemple selon l'exemple de réalisation représenté aux figures 1 à 3 seulement le joint 5, les conformations annulaires 13 et 14 n'étant pas indispensables puisque l'orifice 7 se situe de toute façon en dehors du réservoir.In particular, it is possible to use only one joint, for example according to the embodiment shown in Figures 1 to 3 only the joint 5, the annular conformations 13 and 14 not being essential since the orifice 7 is anyway located outside the tank.

Il est également envisageable de réaliser le revêtement sur une partie seulement d'une conformation annulaire de la demi coque inférieure et de manière complémentaire sur une partie correspondante de la conformation annulaire associée de la demi coque supérieure.It is also possible to realize the coating on only part of an annular conformation of the lower half-shell and so complementary on a corresponding part of the annular conformation associated with the upper half shell.
