Description

La présente invention concerne les pulvérisateurs de fluides du type à gaz propulseur sous pression ou analogue, par exemple ceux à usage domestique pour délivrer des quantités déterminées de produits alimentaires, détergents, assainissants, désodorisants, capillaires, etc., mais aussi les pulvérisateurs pour l'hygiène corporelle et ceux à usage médical.The present invention relates to gas type fluid sprayers pressurized propellant or the like, for example those for household use for deliver specific quantities of food products, detergents, sanitizers, deodorants, capillaries, etc., but also sprayers for personal hygiene and those for medical use.

Les pulvérisateurs qui sont connus actuellement comportent schématiquement une enceinte renfermant le produit à pulvériser, plus généralement à délivrer, au moyen d'un gaz propulseur sous pression, et un embout traversant la paroi de l'enceinte de façon étanche, cet embout comportant un conduit qui débouche respectivement à l'intérieur et à l'extérieur de l'enceinte, l'extrémité de cet embout située à l'intérieur de l'enceinte étant montée en coopération avec un clapet d'obturation et d'ouverture du conduit. Pour obtenir la délivrance d'une quantité déterminée de produit, on agit sur l'embout pour éloigner, du clapet, son extrémité intérieure. Sous l'action de la pression régnant à l'intérieur de l'enceinte, une certaine quantité de produit passe entre le clapet et le bord de l'extrémité intérieure de l'embout, puis est expulsé à l'extérieur de l'enceinte via le conduit.The sprayers which are currently known include schematically an enclosure containing the product to be sprayed, more generally to be delivered, to the by means of a propellant under pressure, and a nozzle passing through the wall of the enclosure in a sealed manner, this end piece comprising a conduit which opens out respectively inside and outside the enclosure, the end of this nozzle located inside the enclosure being mounted in cooperation with a valve closing and opening the duct. To obtain the delivery of a quantity determined by product, we act on the end piece to move its end away from the valve interior. Under the action of the pressure prevailing inside the enclosure, a certain amount of product passes between the valve and the edge of the inner end of the nozzle, then is expelled outside the enclosure via the conduit.

Il est aussi connu, du US-A-5 906 046 et du FR-A-2 153 555, un pulvérisateur comportant une cuvette montée solidaire d'un embout, la cuvette étant apte à être déplacée sous l'action d'une pression exercée sur l'embout. Le préambule de la revendication 1 est basé sur cet état de la technique. Ce type de pulvérisateur présente un inconvénient, notamment dans le cas où il est nécessaire d'effectuer son remplissage après sa réalisation.It is also known, from US-A-5,906,046 and from FR-A-2,153,555, a sprayer comprising a bowl mounted integral with a nozzle, the bowl being able to be moved under the action of pressure exerted on the nozzle. The preamble of claim 1 is based on this state of the art. This kind of a sprayer has a drawback, especially when it is necessary to fill it after completion.

Aussi, la présente invention a-t-elle pour but de pallier les inconvénients mentionnés ci-dessus des pulvérisateurs ou analogues de l'art antérieur, et de réaliser un pulvérisateur qui soit facile à remplir de produit à pulvériser.Also, the present invention aims to overcome the drawbacks mentioned above sprayers or the like of the prior art, and make a sprayer that is easy to fill with spray material.

Similarly, if, on certain figures, elements are not specifically referenced, their reference can be easily found by referring to other figures.

    Il est tout d'abord précisé que, dans la présente description, par "pulvérisateur", on entend tout dispositif comme ceux qui sont par exemple connus sous le terme de "boítiers aérosols" et qui sont aptes à délivrer, sous l'action d'une commande manuelle, une certaine quantité d'un produit fluidique, gazeux, liquide, semi-solide, en micro-particules ou analogue, etc.It is firstly specified that, in the present description, by "sprayer" means any device such as those which are for example known under the term of "aerosol cans" and which are capable of delivering, under the action of a manual control, a certain quantity of a fluidic, gaseous, liquid product, semi-solid, microparticles or the like, etc.

    La figure 1 représente, vu en coupe schématique, une partie d'un mode de réalisation du pulvérisateur selon le préambule de la revendication 1. Ce pulvérisateur comporte une enceinte 1, par exemple celle qui est connue sous le terme de "bombe", comprenant une paroi étanche 2, par exemple en métal comme de l'aluminium ou en plastique rigide ou analogue, délimitant un premier volume 3, un embout tubulaire 4 en un matériau rigide comprenant un conduit 5 le traversant longitudinalement, des moyens d'articulation 6 pour monter l'embout tubulaire 4 dans un orifice 62 de la paroi 2 par un passage relativement étanche 7, de façon à permettre un déplacement de l'embout tubulaire par rapport à cette paroi, les deux extrémités 8, 9 de l'embout tubulaire étant respectivement disposées à l'extérieur 10 et à l'intérieur 11 de l'enceinte. Comme il sera explicité ci-après, ces moyens d'articulation 6 permettent à l'embout 4 de se déplacer par rapport à la paroi 2, dans certaines limites, suivant des mouvements résultant de la combinaison d'une rotation et une translation.Figure 1 shows, seen in schematic section, part of a embodiment of the sprayer according to the preamble of claim 1. This sprayer comprises a enclosure 1, for example that which is known by the term "bomb", comprising a sealed wall 2, for example made of metal such as aluminum or plastic rigid or similar, delimiting a first volume 3, a tubular end piece 4 in one rigid material comprising a conduit 5 traversing it longitudinally, means hinge 6 for mounting the tubular end piece 4 in an orifice 62 of the wall 2 by a relatively sealed passage 7, so as to allow movement of the tubular end piece with respect to this wall, the two ends 8, 9 of the end piece tubular being respectively disposed outside 10 and inside 11 of the enclosure. As will be explained below, these articulation means 6 allow the nozzle 4 to move relative to the wall 2, within certain limits, according to movements resulting from the combination of rotation and translation.

    Le pulvérisateur comporte en outre une cuvette 12 située dans le premier volume 3. Cette cuvette comprend, dans une réalisation la plus simple, un fond 13 et une paroi latérale annulaire 14 solidaire de son fond. Elle est réalisée en un matériau rigide et définit un second volume 15 qui est compris dans le premier volume 3 défini par la paroi de l'enceinte.The sprayer further comprises a bowl 12 located in the first volume 3. This bowl comprises, in a simplest embodiment, a bottom 13 and an annular side wall 14 secured to its bottom. It is made of a material rigid and defines a second volume 15 which is included in the first defined volume 3 through the wall of the enclosure.

    La cuvette est montée solidaire, par son fond 13, du bord 16 de l'ouverture 17 de l'extrémité 9 de l'embout 4 qui est située, comme mentionné auparavant, à l'intérieur de l'enceinte 1, de façon que cette ouverture 17 soit obturée par le fond 13 de la cuvette et que le bord libre 18 de la paroi latérale annulaire 14 de cette cuvette repose de façon étanche sur la face intérieure 19 de la paroi 2 en entourant le passage étanche 7, comme parfaitement visible notamment sur la figure 1.The bowl is mounted integral, by its bottom 13, with the edge 16 of the opening 17 from the end 9 of the end piece 4 which is located, as mentioned before, at inside the enclosure 1, so that this opening 17 is closed by the bottom 13 of the bowl and that the free edge 18 of the annular side wall 14 of this bowl rests tightly on the inner face 19 of the wall 2 surrounding the sealed passage 7, as perfectly visible in particular in FIG. 1.

    Le pulvérisateur comporte aussi des moyens 20 pour mettre en communication le second volume 15 et le conduit 5. The sprayer also includes means 20 for setting communication the second volume 15 and the conduit 5.

    Dans une réalisation avantageuse, les moyens d'articulation 6 pour monter l'embout tubulaire 4 dans un orifice 62 de la paroi 2 de l'enceinte 1 par un passage relativement étanche 7, sont constitués par un manchon 60 en matériau élastique, comme du caoutchouc ou tout autre produit analogue, ce manchon étant monté solidaire, par exemple par dudgeonnage, sertissage, collage, de l'embout 4 et du bord 61 de l'orifice 62 traversant la paroi 2 de l'enceinte 1.In an advantageous embodiment, the articulation means 6 for mounting the tubular end piece 4 in an orifice 62 of the wall 2 of the enclosure 1 by a passage relatively tight 7, are constituted by a sleeve 60 of elastic material, like rubber or any other similar product, this sleeve being mounted secured, for example by swaging, crimping, gluing, of the end piece 4 and the edge 61 of the orifice 62 passing through the wall 2 of the enclosure 1.

    De façon préférentielle, comme illustré sur les figures 5 et 6, le pulvérisateur comporte en outre une couronne 63 en matériau élastique solidarisée par tous moyens avec la face intérieure 19 de la paroi 2 de l'enceinte, en étant interposée entre cette face intérieure 19 et le bord libre 18 de la paroi latérale annulaire 14 de la cuvette 12 de façon à constituer un siège d'étanchéité pour ce bord libre.Preferably, as illustrated in FIGS. 5 and 6, the sprayer further comprises a crown 63 of elastic material secured by all means with the inner face 19 of the wall 2 of the enclosure, being interposed between this inner face 19 and the free edge 18 of the annular side wall 14 of the bowl 12 so as to constitute a sealing seat for this free edge.

    L'un des moyens possibles pour solidariser cette couronne 63 avec la face intérieure 19 de la paroi 2 est constitué par le fait que la couronne 63 et le manchon 60 sont réalisés d'une seule pièce, la fixation du manchon par rapport à la paroi entraínant de facto la fixation de la couronne comme défini ci-dessus.One of the possible means to secure this crown 63 with the face inner 19 of the wall 2 is constituted by the fact that the crown 63 and the sleeve 60 are made in one piece, the fixing of the sleeve relative to the wall causing de facto fixing of the crown as defined above.

    Les moyens 20 pour mettre en communication le second volume 15 et le conduit 5 peuvent être de tous types. Cependant, ils sont avantageusement constitués, comme illustré sur les figures, par au moins une percée traversant la paroi de l'embout 4 à son extrémité intérieure 9 et débouchant respectivement dans le conduit 5 et la partie 21 du second volume 15 entourant extérieurement l'extrémité intérieure 9 de cet embout.The means 20 for communicating the second volume 15 and the conduit 5 can be of all types. However, they are advantageously constituted, as illustrated in the figures, by at least one breakthrough crossing the wall of the end piece 4 at its inner end 9 and opening respectively into the conduit 5 and the part 21 of the second volume 15 externally surrounding the end inner 9 of this nozzle.

    En outre, pour éviter le colmatage de cette percée, sa section est au moins égale à la section transversale du conduit 5, de préférence nettement plus grande. Comme illustré sur les figures 1 à 4, elle est même avantageusement décomposée en une pluralité de percées dont la somme des sections est supérieure à la section transversale du conduit.In addition, to avoid clogging of this breakthrough, its section is at least equal to the cross section of the conduit 5, preferably much larger. As illustrated in Figures 1 to 4, it is even advantageously broken down in a plurality of openings the sum of the sections of which is greater than the section cross section of the duct.

    Le pulvérisateur selon le mode de réalisation décrit ci-dessus en regard des figures 1 et 2 fonctionne et s'utilise de la façon suivante :The sprayer according to the embodiment described above with regard to Figures 1 and 2 works and is used as follows:

    Il est tout d'abord précisé que l'enceinte 1 contient, dans son volume 3, un produit sous pression contenu plus particulièrement dans la partie de ce premier volume 3 qui est extérieure au second volume 15. Le pulvérisateur se trouve dans un état comme celui qui est illustré sur la figure 1, dans lequel le bord libre 18 de la cuvette 12 repose sur la face intérieure 19 de la paroi 2 et assure l'étanchéité entre le second volume 15 et l'intérieur de l'enceinte. Il est à noter que cette étanchéité est en outre assurée par le fait que la pression régnant à l'intérieur de l'enceinte 1 s'applique sur toute la surface de la cuvette 12.It is firstly specified that enclosure 1 contains, in its volume 3, a pressurized product contained more particularly in the part of this first volume 3 which is external to the second volume 15. The sprayer is in a state like that shown in Figure 1, in which the free edge 18 of the bowl 12 rests on the inner face 19 of the wall 2 and seals between the second volume 15 and the interior of the enclosure. It should be noted that this tightness is further ensured by the fact that the pressure prevailing inside the enclosure 1 applies to the entire surface of the bowl 12.

    Lorsqu'un utilisateur veut obtenir une certaine quantité du produit fluidique contenu dans l'enceinte 1, il exerce sur l'extrémité extérieure 8 de l'embout 4 une poussée, représentée schématiquement par la flèche 22, pour tendre à déplacer cet embout par rapport à la paroi 2, ce déplacement étant obtenu grâce au manchon souple 60.When a user wants to obtain a certain quantity of the fluid product contained in the enclosure 1, it exerts on the outer end 8 of the end piece 4 a thrust, represented schematically by arrow 22, to tend to move this end piece relative to wall 2, this displacement being obtained by means of the sleeve flexible 60.

    Comme l'embout 4 est solidaire de la cuvette 12 par le bord 16 de l'ouverture 17 de son extrémité intérieure 9 et le fond 13 de cette cuvette, cette dernière subit corrélativement une rotation autour d'un point 71, figure 2, commun à son bord libre 18 et à la face intérieure 19 de l'enceinte. Cette rotation de la cuvette entraíne un déplacement angulaire de son bord libre 18 par rapport à la face intérieure de la paroi de l'enceinte, figure 2, créant ainsi, pour le produit sous pression contenu dans le premier volume 3, un passage dans le second volume 15, plus particulièrement dans la partie 21 de ce second volumeAs the end piece 4 is integral with the bowl 12 by the edge 16 of the opening 17 of its inner end 9 and the bottom 13 of this bowl, the latter undergoes correlatively a rotation around a point 71, figure 2, common to its free edge 18 and the inner face 19 of the enclosure. This rotation of the bowl causes a angular displacement of its free edge 18 relative to the inner face of the enclosure wall, Figure 2, creating, for the pressure product contained in the first volume 3, a passage in the second volume 15, more particularly in part 21 of this second volume

    La quantité de produit sous pression ainsi passée dans la cuvette 12 est évacuée à l'extérieur 10 de l'enceinte via les percées des moyens de communication 20 et le conduit 5. Le chemin suivi par le produit pour être évacué de l'intérieur 11 de l'enceinte 1 vers l'extérieur 10 est illustré, figure 2, par les flèches 23.The amount of product under pressure thus passed into the bowl 12 is evacuated outside 10 of the enclosure via the openings of the means of communication 20 and the conduit 5. The path followed by the product to be evacuated from the interior 11 of the enclosure 1 towards the outside 10 is illustrated, FIG. 2, by the arrows 23.

    Avec une telle configuration, on constate tout d'abord que l'ouverture ainsi pratiquée entre le bord libre 18 de la cuvette et la face intérieure de la paroi de l'enceinte est relativement grande, le produit sous pression contenu dans l'enceinte pouvant passer par dessus presque tout ce bord libre. De plus, cette ouverture peut parfaitement être modulée suivant une relativement grande amplitude, évitant ainsi par exemple le colmatage de cette ouverture, notamment lorsque le produit à pulvériser est relativement visqueux.With such a configuration, it is noted first of all that the opening thus made between the free edge 18 of the bowl and the inner face of the wall of the enclosure is relatively large, the product under pressure contained in the enclosure being able to pass over almost all this free edge. In addition, this opening can perfectly be modulated over a relatively large amplitude, thus avoiding for example the clogging of this opening, especially when the product spraying is relatively viscous.

    Il est bien précisé que les figures ne sont que des représentations schématiques. Notamment, il sera avantageux de donner à la partie extérieure de l'embout 4 relative à son extrémité extérieure 8 une longueur proportionnellement plus importante par rapport au diamètre du bord libre 18 de la cuvette 12, que celle qui est illustrée sur les figures. En effet, cette partie de l'embout constitue en fait un bras de levier pour obtenir le débattement de la cuvette 12 et il sera d'autant plus facile de moduler avec précision ce débattement que cette partie d'embout sera plus longue. It should be noted that the figures are only representations schematic. In particular, it will be advantageous to give the external part of the end piece 4 relative to its outer end 8 a length proportionally larger compared to the diameter of the free edge 18 of the bowl 12, than that which is illustrated in the figures. In fact, this part of the tip in fact constitutes a lever arm to get the travel of the bowl 12 and it will be all the more easy to precisely modulate this travel as this tip part will be more long.

    Il est aussi à préciser que, lors de son déplacement sous l'effort de poussée 22 exercé par l'utilisateur, l'embout 4 subit, comme visible sur la figure 2, à la fois une rotation et une translation par rapport au passage étanche 7. En conséquence, le manchon sera réalisé de façon à permettre la combinaison de ces deux mouvements. Cette réalisation ne présentant pas de difficulté pour un homme du métier, elle ne sera pas décrite ici avec plus de précision.It should also be noted that when it is moved under the pushing force 22 exerted by the user, the endpiece 4 undergoes, as visible in FIG. 2, both a rotation and a translation relative to the sealed passage 7. Consequently, the sleeve will be made so as to allow the combination of these two movements. This achievement is not difficult for a man of profession, it will not be described here with more precision.

    Il faut aussi noter l'avantage suivant de la structure de pulvérisateur décrite ci-dessus : elle permet à l'utilisateur d'appliquer sur l'embout 4 un effort de poussée 22 suivant n'importe quelle direction tout autour de son extrémité extérieure 8. De ce fait, la cuvette 12 peut pivoter autour de tout point 71 de son bord libre 18, ce qui évite encore plus le risque de colmatage de l'ouverture créée entre l'intérieur 11 de l'enceinte et le volume 15, ainsi que la perte d'étanchéité entre le bord libre 18 de la cuvette et la face intérieure 19 de la paroi de l'enceinte.Note also the following advantage of the sprayer structure described above : it allows the user to apply a thrust force on the end piece 4 in any direction all around its outer end 8. From this done, the bowl 12 can pivot around any point 71 of its free edge 18, which further avoids the risk of clogging of the opening created between the interior 11 of the enclosure and the volume 15, as well as the loss of tightness between the free edge 18 of the bowl and the inner face 19 of the wall of the enclosure.

    La figure 3 représente, vu en coupe schématique, une partie d'un mode de réalisation du pulvérisateur selon l'invention, ce mode de réalisation constituant un perfectionnement de celui illustré sur les figures 1 et 2.Figure 3 shows, seen in schematic section, part of a embodiment of the sprayer according to the invention, this mode of embodiment constituting an improvement of that illustrated in FIGS. 1 and 2.

    Selon ce mode de réalisation, le pulvérisateur comporte, en plus des éléments structurels décrits ci-dessus, au moins une valve commandable 30. Cette valve 30 est montée en coopération avec la portion 31 du fond 13 de la cuvette 12 délimitée par le bord 16 de l'ouverture 17 de l'extrémité intérieure 9 de l'embout 4, et elle est apte à mettre en communication le conduit 5 vers la partie 32 du premier volume 3 située à l'extérieur du second volume 15. Autrement dit, la valve 30 pourra s'ouvrir pour laisser passer un fluide allant du conduit 5 vers la partie 32 du premier volume 3 définie ci-dessus, mais sera fermée pour un fluide tendant à passer dans le sens contraire.According to this embodiment, the sprayer comprises, in addition to the elements structural described above, at least one controllable valve 30. This valve 30 is mounted in cooperation with the portion 31 of the bottom 13 of the demarcated bowl 12 by the edge 16 of the opening 17 of the inner end 9 of the end piece 4, and it is able to connect the conduit 5 to part 32 of the first volume 3 located outside the second volume 15. In other words, the valve 30 can open to let a fluid pass from the conduit 5 towards the part 32 of the first volume 3 defined above, but will be closed for a fluid tending to pass in the direction opposite.

    Dans une réalisation particulièrement avantageuse, cette valve 30 est constituée par une pastille 33 en un matériau élastiquement déformable et une fente 34 réalisée dans la pastille 33, cette fente étant normalement fermée par l'élasticité du matériau constituant la pastille. De façon préférentielle, la pastille 33 constitue au moins une partie de la portion 31 du fond de la cuvette définie ci-dessus et présente, comme illustré sur la figure 3, une forme sensiblement hémisphérique associée au fond 13 de la cuvette de façon que sa face convexe 35 soit située dans la partie 32 du premier volume 3 située à l'extérieur du second volume 15. Préférentiellement, la fente 34 est réalisée dans un plan sensiblement diamétral de cette partie convexe. In a particularly advantageous embodiment, this valve 30 is consisting of a pad 33 of an elastically deformable material and a slot 34 made in the pad 33, this slot being normally closed by the elasticity of the material constituting the pellet. Preferably, the pellet 33 constitutes at minus part of the portion 31 of the bottom of the bowl defined above and present, as illustrated in FIG. 3, a substantially hemispherical shape associated with the bottom 13 of the bowl so that its convex face 35 is located in part 32 of the first volume 3 located outside the second volume 15. Preferably, the slot 34 is produced in a substantially diametral plane of this convex part.

    Le pulvérisateur comportant une valve 30 telle que décrite ci-dessus s'utilise de la façon suivante :The sprayer comprising a valve 30 as described above is used as follows :

    Dans le mode de fonctionnement du pulvérisateur décrit ci-dessus en regard des figures 1 et 2, il a été supposé que le produit sous pression était introduit dans l'enceinte 1 suivant une technique connue de l'art antérieur. Cependant, le perfectionnement selon les figures 3 et 4 apporté à ce pulvérisateur facilite l'introduction du produit sous pression dans le volume 32.In the operating mode of the sprayer described above opposite Figures 1 and 2, it was assumed that the pressurized product was introduced into enclosure 1 according to a technique known from the prior art. However, the improvement according to Figures 3 and 4 brought to this sprayer facilitates the introduction of the product under pressure into volume 32.

    En effet, on suppose tout d'abord que le pulvérisateur est dans la configuration illustré par la combinaison des figures 1 et 3. Quand on veut introduire le produit sous pression dans l'enceinte 1, on utilise une source d'alimentation en ce produit sous pression, dont la sortie est constituée par une aiguille creuse 36. L'extrémité 37 de l'aiguille est introduite dans le conduit 5 jusqu'à ce qu'elle s'insère entre les deux lèvres de la fente 34 pour les écarter (figure 4).Indeed, it is first assumed that the sprayer is in the configuration illustrated by the combination of Figures 1 and 3. When you want to introduce the product under pressure in enclosure 1, a power source is used in this pressurized product, the outlet of which is formed by a hollow needle 36. The end 37 of the needle is introduced into the conduit 5 until it is inserted between the two lips of the slot 34 to separate them (Figure 4).

    Le produit est alors envoyé dans le volume 32 au moyen de cette aiguille 36. Quand la quantité voulue de produit est introduite dans le volume 32, l'aiguille 36 est retirée. Sous les effets conjugués de l'élasticité du matériau constituant la pastille 33 et de la pression exercée par le produit sur la face convexe 35 de la valve, les lèvres de la fente se rapprochent et la fente 34 se referme hermétiquement, assurant ainsi l'étanchéité du volume 32.The product is then sent to volume 32 by means of this needle 36. When the desired quantity of product is introduced into the volume 32, the needle 36 is withdrawn. Under the combined effects of the elasticity of the material constituting the pellet 33 and the pressure exerted by the product on the convex face 35 of the valve, the lips of the slot come closer and the slot 34 is closed hermetically, thus ensuring the tightness of the volume 32.

    L'utilisation et le fonctionnement du pulvérisateur comportant ce perfectionnement selon les figures 3 et 4, pour délivrer le produit sous pression contenu dans l'enceinte, sont identiques à ceux décrits en regard des figures 1 et 2.The use and operation of the sprayer with this improvement according to Figures 3 and 4, to deliver the product under pressure contained in the enclosure, are identical to those described with reference to Figures 1 and 2.

    Les figures 5 et 6 représentent, sous forme schématique, deux modes de réalisation d'un autre perfectionnement apporté au pulvérisateur selon les figures 1 à 4, dans lequel, le gaz propulseur peut être séparé du produit à délivrer.Figures 5 and 6 show, in schematic form, two modes of realization of another improvement made to the sprayer according to FIGS. 1 to 4, in which the propellant gas can be separated from the product to be delivered.

    Il est tout d'abord précisé que les pulvérisateurs illustrés sur ces deux figures comportent, en plus de nouveaux éléments structurels, l'ensemble des éléments structurels du pulvérisateur selon les modes de réalisation décrits en regard des figures 1 à 4.It is firstly specified that the sprayers illustrated in these two figures include, in addition to new structural elements, all of the elements of the sprayer according to the embodiments described with regard to Figures 1 to 4.

    En regard plus précisément de la figure 5, cette figure représente un pulvérisateur selon l'invention comportant en outre une première poche étanche 40 en un matériau élastiquement extensible située dans la partie 32 du premier volume 3 située à l'extérieur du second volume 15. Cette poche étanche 40 comprend une bouche 41 et le pulvérisateur comporte en outre des moyens 42 pour solidariser de façon étanche cette bouche 41 avec la cuvette 12 suivant une première ligne fermée 43 entourant la valve commandable 30 de façon que cette valve permette le passage fluidique entre le conduit 5 et l'intérieur de la première poche 40. Ces moyens de solidarisation 42 peuvent être de tous types. Ils peuvent notamment être constitués par une bague annulaire ou analogue, par exemple soudée ou sertie comme défini ci-dessus, respectivement sur le fond 13 de la cuvette et sur le bord de la bouche 41.Looking more specifically at Figure 5, this figure represents a sprayer according to the invention further comprising a first sealed pocket 40 made of an elastically extensible material located in part 32 of the first volume 3 located outside the second volume 15. This waterproof pocket 40 includes a mouth 41 and the sprayer further comprises means 42 for securing sealingly this mouth 41 with the bowl 12 along a first closed line 43 surrounding the controllable valve 30 so that this valve allows passage fluid between the conduit 5 and the interior of the first pocket 40. These means joining 42 can be of all types. They can in particular be constituted by an annular ring or the like, for example welded or crimped as defined above, respectively on the bottom 13 of the bowl and on the edge of the mouth 41.

    Avec cette réalisation selon la figure 5, le gaz propulseur sous pression est introduit dans la première poche 40, tandis que le fluide à pulvériser est situé dans la partie 44 du premier volume 3 située à l'extérieur du second volume 15 et de la première poche.With this embodiment according to FIG. 5, the propellant gas under pressure is introduced into the first pocket 40, while the fluid to be sprayed is located in the part 44 of the first volume 3 located outside the second volume 15 and the first pocket.

    La figure 6 représente un pulvérisateur selon l'invention comportant une poche étanche 50 en un matériau élastiquement extensible située dans la partie 32 du premier volume 3 située à l'extérieur du second volume 15. Cette poche 50 comprend une bouche 51 et le pulvérisateur comporte en outre des moyens 52 pour solidariser de façon étanche cette bouche 51 avec la face intérieure 19 de la paroi 2 de l'enceinte le long d'une seconde ligne fermée 53 entourant le bord libre 18 de la paroi latérale annulaire 14 de la cuvette 12. Comme mentionné ci-dessus pour les moyens de solidarisation 42, les moyens de solidarisation 52 peuvent être de tous types, par exemple constitués d'une bague annulaire ou analogue soudée ou sertie, respectivement sur la face intérieure 19 de la paroi 2 et sur le bord de la bouche 51.FIG. 6 represents a sprayer according to the invention comprising a pocket waterproof 50 in an elastically extensible material located in part 32 of the first volume 3 located outside the second volume 15. This pocket 50 comprises a mouth 51 and the sprayer further comprises means 52 for secure this mouth 51 tightly with the inner face 19 of the wall 2 of the enclosure along a second closed line 53 surrounding the free edge 18 of the annular side wall 14 of the bowl 12. As mentioned above for the securing means 42, the securing means 52 can be of all types, for example made of an annular ring or the like welded or crimped, respectively on the inner face 19 of the wall 2 and on the edge of the mouth 51.

    Dans cette réalisation, le gaz propulseur est introduit dans la partie 54 du premier volume 3 située à l'extérieur de la poche 50, tandis que le fluide à pulvériser est situé dans cette poche.In this embodiment, the propellant is introduced into part 54 of the first volume 3 located outside the pocket 50, while the fluid to be sprayed is located in this pocket.

    Le fonctionnement et l'utilisation du pulvérisateur selon les modes de réalisation illustrés sur les figures 5 et 6 se déduisent aisément des descriptions faites auparavant, aussi bien des fonctionnements et utilisations en regard des figures 1 à 4 que des modes de réalisation selon ces figures 5 et 6. Ils ne seront donc pas plus amplement développés ici.Operation and use of the sprayer according to the modes of embodiments illustrated in FIGS. 5 and 6 are easily deduced from the descriptions beforehand, both operations and uses with regard to Figures 1 to 4 only embodiments according to these Figures 5 and 6. They will not therefore not more fully developed here.

    A la lecture de la description faite ci-dessus, il apparaít nettement que la structure du pulvérisateur selon l'invention lui permet de présenter de nombreux avantages par rapport aux pulvérisateurs de l'art antérieur. Ces avantages ont été décrits tout au long de la présente description et ne seront donc pas rappelés ici.Reading the description given above, it clearly appears that the structure of the sprayer according to the invention allows it to present numerous advantages over sprayers of the prior art. These benefits have been described throughout this description and will therefore not be repeated here.
