Description

Distributeur de produit liquide ou en gel formant bâton doseurLiquid or gel dispenser forming a dosing stick
La présente invention concerne un distributeur de produit liquide ou en gel, tel qu'un produit cosmétique ou pharmaceutique.The present invention relates to a liquid or gel product dispenser, such as a cosmetic or pharmaceutical product.
Il existe déjà des distributeurs du type comprenant un réservoir supportant un corps de pompe obturé en partie basse par un clapet d'admission et pourvu en partie haute d'un piston délimitant, avec le corps, une chambre de dosage comportant au moins un orifice d'éjection, le corps de pompe coopérant avec un embout de distribution déplaçable axialement sur le réservoir. Cependant, dans de tels distributeurs, s'il existe un clapet obturateur destiné à arrêter l'échappement du produit, celui-ci est situé dans la pompe et à une distance appréciable de l'orifice d'éjection. Or, la présence d'un reliquat de produit dans la zone au contact de l'atmosphère extérieure est susceptible d'obstruer, par séchage, les voies de distribution et/ou d'induire des risques de contamination.There are already dispensers of the type comprising a reservoir supporting a pump body closed at the bottom by an intake valve and provided at the top with a piston delimiting, with the body, a metering chamber comprising at least one orifice ejection, the pump body cooperating with a dispensing tip axially displaceable on the tank. However, in such dispensers, if there is a shutter valve intended to stop the escape of the product, it is located in the pump and at a considerable distance from the ejection orifice. However, the presence of a residue of product in the zone in contact with the external atmosphere is likely to obstruct, by drying, the distribution channels and / or to induce risks of contamination.
En outre, ces distributeurs utilisent des moyens de rappel du piston en position haute, sous forme d'un ou plusieurs ressorts métalliques. De telles ressorts ne sont pas toujours compatibles chimiquement ou biologiquement avec les produits conditionnés. Enfin, l'étanchéité de la partie basse du corps de pompe n'est pas suffisamment fiable, ce qui compromet la précision du dosage.In addition, these distributors use means for returning the piston to the high position, in the form of one or more metal springs. Such springs are not always chemically or biologically compatible with the packaged products. Finally, the sealing of the lower part of the pump body is not sufficiently reliable, which compromises the accuracy of the metering.
La présente invention a pour but de résoudre ces différents problèmes techniques de manière satisfaisante.The present invention aims to solve these various technical problems satisfactorily.
Plus particulièrement, l'invention concerne un distributeur de produit liquide ou en gel, du type comprenant un réservoir supportant un corps de pompe comportant en partie basse un clapet d'admission et pourvu d'un piston mobile suivant un axe, délimitant avec ledit corps une chambre de dosage en communication avec au moins un orifice d'éjection défini dans un embout de distribution déplaçable axialement à l'extrémité dudit réservoir, caractérisé en ce que ledit piston est couplé par friction audit embout de distribution, lequel est déplaçable axialement dans les deux sens par actionnement manuel, relativement audit réservoir, entre deux positions prédéterminées, en ce que ladite chambre de dosage comporte, d'une part, un compartiment inférieur défini entre ledit corps et ledit piston et, d'autre part, un compartiment supérieur défini entre le piston et ledit embout, les deux compartiments communiquant via un conduit ménagé au travers dudit piston et en ce qu'un clapet obturateur est agencé entre ledit piston et ledit embout pour isoler ladite chambre de dosage dudit orifice.More particularly, the invention relates to a liquid or gel product dispenser, of the type comprising a reservoir supporting a pump body comprising in the lower part an inlet valve and provided with a piston movable along an axis, delimiting with said body a metering chamber in communication with at least one ejection orifice defined in a dispensing tip axially displaceable at the end of said reservoir, characterized in that said piston is frictionally coupled to said dispensing tip, which is axially displaceable in the two directions by manual actuation, relative to said reservoir, between two predetermined positions, in that said metering chamber comprises, on the one hand, a lower compartment defined between said body and said piston and, on the other hand, an upper defined compartment between the piston and said nozzle, the two compartments communicating via a conduit formed through said piston and in that a shutter valve is arranged between said piston and said nozzle to isolate said metering chamber from said orifice.
Selon un mode de réalisation possible, l'embout a la forme d'un capuchon agencé pour envelopper partiellement ledit réservoir, ledit capuchon présentant une paroi supérieure, sensiblement perpendiculaire audit axe, dans laquelle est pratiqué ledit orifice d'éjection. Comme cette paroi peut être relativement mince, le ou chaque orifice d'éjection se résume à un trou de faible longueur dans lequel la quantité de produit susceptible de sécher est infime. Selon l'un des modes de réalisation, le piston vient directement au contact de ce trou, à l'intérieur et selon un autre mode de réalisation, le clapet obturateur comporte un élément d'obturation porté par le piston et qui s'engage de manière étanche dans l'orifice d'éjection lui-même de sorte qu'aucune quantité de produit n'est susceptible de sécher.According to a possible embodiment, the nozzle has the form of a cap arranged to partially envelop said reservoir, said cap having an upper wall, substantially perpendicular to said axis, in which said ejection orifice is formed. As this wall can be relatively thin, the or each ejection orifice boils down to a short hole in which the quantity of product liable to dry is minute. According to one of the embodiments, the piston comes directly into contact with this hole, inside and according to another embodiment, the shutter valve comprises a shutter element carried by the piston and which engages tightly in the ejection port itself so that no amount of product is likely to dry.
Selon une caractéristique avantageuse, le piston porte une collerette, extérieure au corps de pompe qui coulisse de façon étanche à l'intérieur de l'embout en comprimant le produit dans le compartiment supérieur, pour le refouler vers l'extérieur. Selon une autre caractéristique avantageuse, la collerette comporte un épaulement supérieur prolongé à sa périphérie et vers le bas par une jupe latérale. Cette dernière coulisse avec un certain frottement dans l'embout lui-même.According to an advantageous characteristic, the piston carries a flange, external to the pump body which slides in leaktight manner inside the nozzle by compressing the product in the upper compartment, to discharge it outwards. According to another advantageous characteristic, the collar has an upper shoulder extended at its periphery and downwards by a side skirt. The latter slides with a certain friction in the nozzle itself.
De préférence, le bord inférieur de cette jupe est pourvu d'un jonc de retenu coopérant avec un rebord supérieur du corps de pompe, pour assurer la butée de la collerette en position haute.Preferably, the lower edge of this skirt is provided with a retaining ring cooperating with an upper rim of the pump body, to ensure the stop of the flange in the high position.
Selon une première variante, un ou plusieurs orifices d'éjection sont ménagés au travers de la paroi supérieure de l'embout au droit de ladite collerette du piston. Selon une autre variante, l'orifice d'éjection, unique, est ménagé au travers de la paroi supérieure de l'embout dans l'axe du conduit central du piston. L'élément d'obturation, porté par le piston est susceptible de s'engager dans cet orifice d'éjection.According to a first variant, one or more ejection orifices are formed through the upper wall of the end piece in line with said collar of the piston. According to another variant, the single ejection orifice is formed through the upper wall of the end piece in the axis of the central duct of the piston. The closure element, carried by the piston, is capable of engaging in this ejection orifice.
Selon une autre variante, le clapet d'obturation comporte un élément d'obturation faisant saillie de la face interne de ladite paroi supérieure de l'embout, axialement. Cet élément d'obturation est susceptible de s'engager de manière étanche dans la partie haute du conduit centrale du piston.According to another variant, the shutter valve comprises a shutter element projecting from the internal face of said upper wall of the endpiece, axially. This shutter element is capable of sealingly engaging in the upper part of the central duct of the piston.
Selon une autre caractéristique, le corps de pompe est pourvu, en partie haute, d'une gorge périphérique dans laquelle coulisse axialement une lèvre annulaire d'étanchéité .solidaire de ladite collerette du piston.According to another characteristic, the pump body is provided, in the upper part, with a peripheral groove in which axially slides an annular sealing lip .solidated from said collar of the piston.
Selon une variante , le réservoir comprend un flacon recevant une douille interne de support du corps de pompe. L'embout de distribution est monté de manière mobile sur cette douille. Selon une variante, la paroi interne du réservoir comporte un jeu d'ailettes d'arrêt, flexibles, coopérant avec des ailettes complémentaires portées par l'embout.According to a variant, the reservoir comprises a bottle receiving an internal socket for supporting the pump body. The dispensing tip is movably mounted on this socket. According to a variant, the internal wall of the reservoir comprises a set of flexible stop fins, cooperating with complementary fins carried by the end piece.
La configuration du distributeur selon l'invention, muni d'une chambre en deux compartiments forme un sas d'évacuation favorisant une distribution régulière du produit.The configuration of the dispenser according to the invention, provided with a chamber in two compartments forms an airlock promoting a regular distribution of the product.
Par ailleurs, l'emplacement du clapet obturateur permet d'assurer une étanchéité haute, ce qui garantit l'herméticité du distributeur et la protection du produit.In addition, the location of the shutter valve ensures high tightness, which guarantees the hermeticity of the dispenser and the protection of the product.
En outre, l'étanchéité basse est renforcée par le verrouillage du clapet d'admission en position de fermeture, au moyen du piston lui- même.In addition, the lower seal is reinforced by locking the intake valve in the closed position, by means of the piston itself.
L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels : la figure 1 est une vue en perspective d'un premier mode de réalisation du distributeur de l'invention ; les figures 2A à 2D représentent des vues en coupe verticale du distributeur de la figure 1 dans différentes positions ; la figure 3 représente une vue en coupe horizontale du distributeur de la figure 1 dans la position de la figure 2A ; la figure 4 est une vue en perspective d'un second mode de réalisation du distributeur de l'invention ; et les figures 5A et 5B représentent des vues en coupe verticale du distributeur de la figure 4 en position, respectivement, de fermeture et d'ouverture. Le distributeur représenté sur les figures est plus particulièrement destiné au conditionnement de produits cosmétiques ou pharmaceutiques. Comme représenté sur la figure 1 , le premier mode de réalisation du distributeur a une forme cylindrique assimilable à un bâton.The invention will be better understood on reading the description which follows with reference to the drawings in which: FIG. 1 is a perspective view of a first embodiment of the dispenser of the invention; Figures 2A to 2D show views in vertical section of the dispenser of Figure 1 in different positions; 3 shows a horizontal sectional view of the dispenser of Figure 1 in the position of Figure 2A; Figure 4 is a perspective view of a second embodiment of the dispenser of the invention; and FIGS. 5A and 5B show views in vertical section of the dispenser of FIG. 4 in the closed and open positions, respectively. The dispenser shown in the figures is more particularly intended for the packaging of cosmetic products or pharmaceuticals. As shown in Figure 1, the first embodiment of the dispenser has a cylindrical shape similar to a stick.
Ce distributeur comprend un réservoir R supportant un corps de pompe 1 obturé en partie basse par un clapet d'admission 2 et prolongé par un tube de prise 11 s'étendant à l'intérieur du réservoir. Le clapet 2 est constitué d'une bille 21 logée dans une partie tronconique 12 du corps de pompe 1 , lequel délimite un canal d'alimentation. La bille dispose, entre deux butées, d'une liberté de déplacement axial.This dispenser comprises a reservoir R supporting a pump body 1 closed at the bottom by an intake valve 2 and extended by an intake tube 11 extending inside the reservoir. The valve 2 consists of a ball 21 housed in a frustoconical part 12 of the pump body 1, which delimits a supply channel. The ball has, between two stops, a freedom of axial movement.
Le réservoir R est surmonté d'un embout de distribution E dans la paroi duquel sont ménagés quatre orifices d'éjection e. L'embout E a la forme d'un capuchon globalement cylindrique, comme décrit ci-dessus. Le corps 1 est pourvu, en partie haute, d'un piston 3 délimitant avec le corps 1 et l'embout E une chambre de dosage communiquant avec les orifices d'éjection e. Un clapet obturateur 5 est défini entre l'embout E et le piston 3. L'embout E est déplaçable axialement par rapport au réservoir R, on peut par exemple prévoir un déplacement axial en translation et coulissement de l'embout E par rapport au réservoir ou, selon une variante non représentée, un déplacement axial par vissage/dévissage de l'embout E sur le réservoir R. Dans le mode de réalisation des figures 2A à 2D, le réservoir R comprend un flacon F recevant une douille interne d de support du corps de pompe 1.The reservoir R is surmounted by a dispensing nozzle E in the wall of which are formed four ejection orifices e. The tip E has the shape of a generally cylindrical cap, as described above. The body 1 is provided, in the upper part, with a piston 3 delimiting with the body 1 and the nozzle E a metering chamber communicating with the ejection orifices e. A shutter valve 5 is defined between the end piece E and the piston 3. The end piece E is axially movable relative to the reservoir R, it is for example possible to provide an axial displacement in translation and sliding of the end piece E relative to the reservoir or, according to a variant not shown, an axial displacement by screwing / unscrewing the end piece E on the reservoir R. In the embodiment of FIGS. 2A to 2D, the reservoir R comprises a bottle F receiving an internal socket d of support of the pump body 1.

Elle est conformée pour délimiter avec le réservoir, un espace annulaire 6 dans lequel est logée et se déplace en translation et/ou en rotation la paroi de l'embout E. Le corps de pompe 1 est pourvu d'un orifice d'évent 14 pratiqué au travers de sa paroi latérale dans la partie qui se trouve à l'intérieur du réservoir R et permettant la reprise d'air. Cet orifice 14 est associé ici à une rainure 15 du fait que la partie haute du corps 1 est aussi emmanchée avec un léger serrage radial dans le col de la douille d.The bushing d is fitted at its lower part into the neck of the tank with a radial clamping. It is shaped to define with the reservoir, an annular space 6 in which is housed and moves in translation and / or in rotation the wall of the nozzle E. The pump body 1 is provided with a vent orifice 14 practiced through its side wall in the part which is inside the tank R and allowing the air intake. This orifice 14 is associated here with a groove 15 because the upper part of the body 1 is also fitted with a slight radial tightening in the neck of the sleeve d.
La chambre de dosage est formée, d'une part, d'un compartiment inférieur 10a situé entre le corps 1 et la partie centrale cylindrique 3a du piston 3 et, d'autre part, d'un compartiment supérieur 10b situé entre le piston 3 et la paroi interne de l'embout E (voir figures 2C, 2D et 5B). Les compartiments inférieur 10a et supérieur 10b sont de volumes variables et sont susceptibles de communiquer l'un avec l'autre via un conduit 30 ménagé ici axialement au travers de la partie centrale 3a du piston 3.The metering chamber is formed, on the one hand, by a lower compartment 10a situated between the body 1 and the cylindrical central part 3a of the piston 3 and, on the other hand, by an upper compartment 10b situated between the piston 3 and the internal wall of the end piece E (see FIGS. 2C, 2D and 5B). The lower compartments 10a and upper 10b are of variable volumes and are capable of communicating with each other via a conduit 30 formed here axially through the central part 3a of the piston 3.
Le piston 3 porte une collerette 31 extérieure au corps 1 , qui délimite une partie du compartiment 10b et qui est susceptible de coulisser de façon étanche à l'intérieur de l'embout E pour comprimer le produit dans le compartiment supérieur 10b.The piston 3 carries a flange 31 external to the body 1, which delimits a part of the compartment 10b and which is capable of sliding in leaktight manner inside the end piece E to compress the product in the upper compartment 10b.
Le piston 3 est mobile en translation, axialement à la fois par rapport au corps de pompe 1 et par rapport à l'embout E. Il est couplé par friction à l'embout E, grâce à la jupe 31 c. Il vient en butée, vers le bas, contre la bille 21 du clapet d'admission 2 et vers le haut contre la face interne de la paroi supérieure 7 de l'embout E. Cette paroi est, comme on voit, sensiblement perpendiculaire à l'axe de déplacement du piston.The piston 3 is movable in translation, axially both with respect to the pump body 1 and with respect to the nozzle E. It is frictionally coupled to the nozzle E, thanks to the skirt 31c. It abuts, downwards, against the ball 21 of the intake valve 2 and upwards against the internal face of the upper wall 7 of the nozzle E. This wall is, as can be seen, substantially perpendicular to the axis of displacement of the piston.
Le piston 3 exerce ainsi une double action, successivement dans le compartiment inférieur 10a puis dans le compartiment supérieur 10b de la chambre de dosage, conduisant à une éjection du produit en deux temps.The piston 3 thus exerts a double action, successively in the lower compartment 10a then in the upper compartment 10b of the metering chamber, leading to an ejection of the product in two stages.
La collerette 31 comporte un épaulement supérieur 31a prolongé à sa périphérie et vers le bas par une jupe latérale 31b coulissant avec un léger frottement contre la paroi latérale intérieure cylindrique de l'embout E. Le bord inférieur de la jupe 31b est pourvu d'un jonc de retenue 31 c coopérant avec un rebord supérieur 1 a du corps 1 , pour assurer la butée haute de la collerette 31.The flange 31 has an upper shoulder 31a extended at its periphery and downwards by a sliding side skirt 31b with a slight friction against the cylindrical inner side wall of the end piece E. The bottom edge of the skirt 31b is provided with a retaining ring 31 c cooperating with an upper rim 1 a of the body 1, to ensure the upper stop of the flange 31.
Dans le mode de réalisation des figures 1 à 3, le clapet obturateur 5 est constitué d'un élément d'obturation sous forme d'un pointeau 4, faisant saillie de la face intérieure de la paroi 7 de l'embout E. Ce pointeau est susceptible de s'engager à coulissement étanche dans la partie haute du conduit 30 du piston. Quatre orifices d'éjection e sont agencés autour de ce pointeau. L'étanchéité de la fermeture du clapet obturateur est ici principalement obtenue par l'engagement à coulissement doux du pointeau 4 dans la partie haute du conduit 30. Cependant, comme les orifices sont ici ménagés au travers de la paroi supérieure de l'embout E, en regard de Pépaulement 31a de la collerette 31 , on dispose d'une paroi obturante complémentaire. Le fonctionnement du mode de réalisation décrit aux figures 1 à 3 est le suivant : A la montée de l'embout E à partir de la position représentée sur la figure 2A, le piston est entraîné vers le haut par friction en restant bloqué dans l'embout E, ce qui provoque l'ouverture du clapet d'admission et le remplissage du compartiment inférieur (fig. 2B) jusqu'à ce que le jonc 31c du piston arrive en butée contre le rebord 1a du corps de pompe. La poursuite du dévissage sépare l'embout du piston en libérant le compartiment supérieur 10b qui se remplit à son tour. Ce déplacement s'accompagne du dégagement des orifices d'éjection e et prépare le système pour la distribution du produit (fig. 2C). A la descente, l'embout se déplace en entraînant d'abord le piston 3 retenu par serrage radial, les orifices d'éjection étant ouverts et le clapet d'admission 2 fermé. La compression du produit dans le compartiment inférieur 10a assure son éjection. Lorsque le piston arrive en butée contre le corps de pompe, la fermeture du clapet d'admission 2 est confirmée et l'embout E poursuit sa descente en comprimant le produit dans le compartiment supérieur 10b (fig. 2D) jusqu'à ce que les orifices d'éjection e soient obturés de l'intérieur.In the embodiment of Figures 1 to 3, the shutter valve 5 consists of a shutter element in the form of a needle 4, projecting from the inner face of the wall 7 of the nozzle E. This needle is likely to engage in leaktight sliding in the upper part of the conduit 30 of the piston. Four ejection orifices e are arranged around this needle. The tightness of the closure of the shutter valve is here mainly obtained by the smooth sliding engagement of the needle 4 in the upper part of the duct 30. However, as the orifices are here formed through the upper wall of the end piece E , opposite the shoulder 31a of the collar 31, there is a complementary sealing wall. The operation of the embodiment described in Figures 1 to 3 is as follows: When the nozzle E rises from the position shown in FIG. 2A, the piston is driven upwards by friction while remaining locked in the nozzle E, which causes the inlet valve to open and the filling the lower compartment (fig. 2B) until the rod 31c of the piston abuts against the flange 1a of the pump body. Continued unscrewing separates the end piece from the piston, freeing the upper compartment 10b which in turn fills. This displacement is accompanied by the release of the ejection orifices and prepares the system for the distribution of the product (fig. 2C). On descent, the nozzle moves by first driving the piston 3 retained by radial tightening, the ejection orifices being open and the intake valve 2 closed. The compression of the product in the lower compartment 10a ensures its ejection. When the piston comes into abutment against the pump body, the closing of the intake valve 2 is confirmed and the nozzle E continues its descent by compressing the product in the upper compartment 10b (fig. 2D) until the ejection ports are closed from the inside.
En fin de course, des moyens de blocage 46 fonctionnant par effet de clipsage, stabilisent la position de l'embout E par rapport au réservoir R. Ces moyens de blocage sont ici constitués d'un jonc annulaire 47 prévu à l'extérieur de la douille d et d'une gorge annulaire correspondante 48 ménagée à la base de la paroi intérieure de l'embout E. Ces moyens de blocage confirment et renforcent la fermeture du clapet d'admission 2 et celle du clapet obturateur 5. Dans le mode de réalisation des figures 4, 5A et 5B, les parties analogues à celles du mode de réalisation des figures 1 à 3 portent les mêmes références alphanumériques. L'élément d'obturation est porté par le piston 3 et est susceptible de s'engager à coulissement étanche dans un orifice d'éjection e', unique, de l'embout E. Il comprend un ergot 32 solidaire de la collerette 31 et s'étendant coaxialement au conduit 30.At the end of the race, blocking means 46 operating by clipping effect, stabilize the position of the end piece E relative to the reservoir R. These blocking means here consist of an annular ring 47 provided outside the socket d and a corresponding annular groove 48 formed at the base of the inner wall of the end piece E. These blocking means confirm and reinforce the closing of the intake valve 2 and that of the shutter valve 5. In the mode of embodiment of FIGS. 4, 5A and 5B, the parts similar to those of the embodiment of FIGS. 1 to 3 bear the same alphanumeric references. The closure element is carried by the piston 3 and is capable of engaging in leaktight sliding in a single ejection orifice e ′ of the end piece E. It comprises a lug 32 secured to the flange 31 and extending coaxially to conduit 30.
L'orifice d'éjection e', unique, est réalisé au travers de la paroi supérieure de l'embout E dans l'axe du conduit 30 mais avec ici un diamètre supérieur à celui des orifices e du mode de réalisation précédemment décrit. L'orifice e' est de section cylindroconique tandis que l'ergot 32 est cylindrique. Le conduit central 30 débouche ici dans le compartiment supérieur 10b de la chambre de dosage, par des lumières 34 ménagées dans répaulement 31a, définies entre des pontets de liaison, autour de l'ergot 32. Dans ce second mode de réalisation, le corps de pompe 1 est pourvu, en partie haute, d'une gorge périphérique 13 dans laquelle coulisse une lèvre d'étanchéité annulaire 33 raccordée au piston 3. Elle est portée par la face inférieure de l'épaulement 31a de la collerette 31.The ejection orifice e ′, which is unique, is produced through the upper wall of the end piece E in the axis of the conduit 30 but here with a diameter greater than that of the orifices e of the embodiment described above. The opening e 'is of cylindroconical section while the lug 32 is cylindrical. The central conduit 30 opens here in the upper compartment 10b of the metering chamber, through slots 34 formed in shoulder 31a, defined between connecting bridges, around the lug 32. In this second embodiment, the body of pump 1 is provided, in the upper part, with a peripheral groove 13 in which slides an annular sealing lip 33 connected to the piston 3. It is carried by the underside of the shoulder 31a of the flange 31.
Un orifice d'évent 14 est pratiqué entre la paroi latérale supérieure du corps et la gorge 13. Cet orifice est associé à une rainure 15 du fait que. la partie haute du corps 1 est emmanchée avec un léger serrage radial dans la douille d. L'air peut s'écouler entre la douille d et l'embout E (voir fig. 5B).A vent orifice 14 is formed between the upper side wall of the body and the groove 13. This orifice is associated with a groove 15 because . the upper part of the body 1 is fitted with a slight radial tightening in the sleeve d. Air can flow between the bushing d and the nozzle E (see fig. 5B).
La paroi latérale de la lèvre 33 présente un retreint 35 sur sa face radialement extérieure et s'étendant sur une hauteur h. Ce retreint délimite un passage pour la reprise d'air, dans le réservoir R, via l'orificeThe lateral wall of the lip 33 has a constriction 35 on its radially outer face and extending over a height h. This constriction delimits a passage for the return of air, into the reservoir R, via the orifice
14, en position haute de la collerette 31.14, in the high position of the collar 31.
La paroi interne du réservoir R et plus précisément du flacon F comporte un jeu d'ailettes d'arrêt flexibles a coopérant avec des ailettes complémentaires a portées par la partie inférieure de la paroi latérale externe de l'embout E.The internal wall of the reservoir R and more precisely of the bottle F comprises a set of flexible stop fins a cooperating with complementary fins carried by the lower part of the external lateral wall of the end piece E.
La souplesse des ailettes a, a' permet l'introduction du bord inférieur de l'embout E dans l'espace intercalaire situé entre le flacon F et la douille d. Lorsque l'embout E arrive en position haute, les ailettes §1 de l'embout viennent se caler en butée contre les ailettes a du flacon et interdisent toute séparation.The flexibility of the fins a, a 'allows the introduction of the lower edge of the nozzle E in the intermediate space located between the bottle F and the sleeve d. When the nozzle E arrives in the high position, the fins §1 of the nozzle are wedged in abutment against the fins a of the bottle and prohibit any separation.
Ce mode de réalisation permet un conditionnement aisé du produit dans le réservoir R, en remplissant la douille d à l'envers avec l'embout E en position de fermeture. Le flacon F est ensuite monté à la manière d'un bouchon sur la douille d pour former le fond du réservoir avant que le distributeur ne soit retourné.This embodiment allows easy packaging of the product in the reservoir R, by filling the sleeve d upside down with the nozzle E in the closed position. The bottle F is then mounted in the manner of a cap on the socket d to form the bottom of the tank before the dispenser is turned over.
Le mode de fonctionnement du distributeur selon ce second mode de réalisation est décrit ci-après. Dans la position représentée sur la figures 5A, l'extrémité du piston vient, par le bord inférieur du conduit 30, en appui vers le bas contre la bille 21 pour verrouiller le clapet d'admission en position de fermeture. Les moyens de blocage 46 confirment ce verrouillage.The operating mode of the dispenser according to this second embodiment is described below. In the position shown in FIGS. 5A, the end of the piston comes, by the lower edge of the conduit 30, to bear downwards against the ball 21 to lock the intake valve in the closed position. The locking means 46 confirm this locking.
Dans cette position, le volume de la chambre de dosage est minimal du fait que l'embout E est en position basse au contact de l'épaulement 31a de la collerette 31. Les volumes libres des compartiments 10a et 10b sont pratiquement nuls.In this position, the volume of the metering chamber is minimal because the end piece E is in the low position in contact with the shoulder 31a of the flange 31. The free volumes of the compartments 10a and 10b are practically zero.
L'élément d'obturation 32 est engagé dans l'orifice d'éjection e' (fig. 5A) ce qui garantit une étanchéité complète du distributeur sans contact d'une quelconque fraction du produit avec l'atmosphère. Lorsque l'embout E est déplacé à partir de la position précédente, vers le haut, en entraînant avec lui la collerette 31 du piston 3, le clapet d'admission s'ouvre et le compartiment inférieur 10a se remplit de produit. Le mouvement se poursuit jusqu'à ce que le jonc 31c vienne en butée contre le bord supérieur du corps 1. La poursuite du déplacement de l'embout E entraîne la séparation entre celui-ci et la collerette 31 du piston (fig. 5B) qui reste en butée contre le corps 1. Ceci dégage le conduit central 30 et l'orifice d'éjection e'. On obtient ainsi une ouverture du clapet obturateur.The closure element 32 is engaged in the ejection orifice e ′ (FIG. 5A) which guarantees complete sealing of the dispenser without contact of any fraction of the product with the atmosphere. When the nozzle E is moved from the previous position, upwards, by driving with it the flange 31 of the piston 3, the intake valve opens and the lower compartment 10a is filled with product. The movement continues until the rod 31c comes into abutment against the upper edge of the body 1. The further movement of the end piece E causes the separation between the latter and the flange 31 of the piston (fig. 5B) which remains in abutment against the body 1. This releases the central duct 30 and the ejection orifice e '. There is thus obtained an opening of the shutter valve.
Ensuite, la poursuite du mouvement de l'embout E s'accompagne du remplissage du compartiment supérieur 10b de la chambre de dosage comme représenté sur la figure 5B, tout en comprimant le produit dans les deux compartiments de la chambre, ce qui assure sa distribution par l'orifice e'.Then, the continued movement of the nozzle E is accompanied by the filling of the upper compartment 10b of the metering chamber as shown in FIG. 5B, while compressing the product in the two compartments of the chamber, which ensures its distribution through the opening e '.
Il est remarquable que dans les deux modes de réalisation décrits ci-dessus, le clapet obturateur est agencé à proximité immédiate du ou des orifices d'éjection (e ou e') ménagés dans la paroi d'extrémité de l'embout E. Ainsi, on évite que du produit soit au contact de l'atmosphère lorsque le distributeur est fermé. On élimine donc le risque de bouchage du dispositif par séchage d'une quantité excessive de produit ainsi que le risque de contamination de ce produit. It is remarkable that in the two embodiments described above, the shutter valve is arranged in the immediate vicinity of the ejection orifice (s) (e or e ') formed in the end wall of the end piece E. Thus , it is avoided that the product is in contact with the atmosphere when the dispenser is closed. The risk of blockage of the device is therefore eliminated by drying an excessive quantity of product as well as the risk of contamination of this product.
