La présente invention concerne un distributeur de produits liquides et plus particulièrement de produits pharmaceutiques liquides destinés à être délivrés par pulvérisation ou par jet.The present invention relates to a product distributor liquids and more particularly liquid pharmaceutical products intended to be delivered by spray or jet.

Il existe déjà des distributeurs de produits liquides du type comprenant notamment un réservoir équipé de moyens de prélèvement du produit tels qu'une valve ou une pompe sur lesquels est montée une tête de distribution.There are already distributors of liquid products of the type comprising in particular a tank equipped with sampling means of the product such as a valve or a pump on which is mounted a distribution head.

Ces moyens de prélèvement sont susceptibles d'être actionnés par déplacement axial du réservoir relativement à un tube gicleur alimenté par les moyens de prélèvement et dont une partie fait saillie à l'extérieur en étant coiffée par ladite tête.These sampling means are likely to be activated by axial displacement of the reservoir relative to a nozzle tube supplied by the sampling means and a part of which projects the exterior being capped by said head.

Le document US-3 272 392 décrit un distributeur selon le préambule de la revendication 1.Document US-3,272,392 describes a dispenser according to the preamble of claim 1.

Cependant, pour certains produits pharmaceutiques comme par exemple, les produits homéopathiques ou ophtalmiques les doses à administrer correspondent à des volumes très faibles de l'ordre de 30 à 50 microlitres.However, for certain pharmaceutical products such as example, homeopathic or ophthalmic products the doses at administer correspond to very low volumes of the order of 30 to 50 microliters.

Dans ces conditions, le produit est conditionné dans des réservoirs constitués de flacons de faibles contenus et donc de dimensions réduites, ce qui rend leur utilisation délicate.Under these conditions, the product is packaged in tanks made up of bottles of low contents and therefore of reduced dimensions, which makes their use delicate.

En particulier, la tête coiffant le tube gicleur possède alors de faibles dimensions qui ne sont pas adaptées aux nombreuses manipulations pourtant nécessaires à l'obtention du déplacement axial du tube gicleur.In particular, the head covering the nozzle tube then has small dimensions which are not suitable for many manipulations however necessary to obtain the axial displacement of the spray tube.

La présente invention a pour but de résoudre ces problèmes techniques en offrant un emballage dont la maniabilité est améliorée et ceci indépendamment des doses de produit à délivrer.The object of the present invention is to solve these problems techniques by offering packaging with improved handling and this independently of the doses of product to be delivered.

Ce but est atteint, conformément à l'invention au moyen d'un distributeur du type précédent caractérisé en ce qu'il comporte au moins une ailette latérale en prise avec le réservoir ou le tube gicleur et portant une came destinée à coopérer par contact de glissement avec au moins une paroi inclinée solidaire dudit embout, de telle sorte qu'une poussée sensiblement radiale sur ladite ailette se traduise par un déplacement. axial du tube relativement au réservoir en entraínant la délivrance du produit.This object is achieved, in accordance with the invention by means of a dispenser of the previous type characterized in that it comprises at least one fin side in engagement with the reservoir or the spray tube and carrying a cam intended to cooperate by sliding contact with at least one wall inclined integral with said tip, so that a thrust substantially radial on said fin results in displacement. axial of the tube relative to the reservoir causing the delivery of product.

Selon une caractéristique avantageuse, le réservoir est enfermé de manière amovible dans le boítier, délimité à sa partie supérieure par ledit embout.According to an advantageous characteristic, the tank is enclosed removably in the housing, delimited at its upper part by said tip.

Selon une autre caractéristique, ladite ailette comporte un flanc extérieur formant bouton-poussoir dont les génératrices sont au moins partiellement parallèles à celles du conduit.According to another characteristic, said fin has a sidewall exterior forming a push button whose generators are at least partially parallel to those of the duct.

De préférence, ledit flanc extérieur formant bouton-poussoir s'étend de façon affleurante dans des ouvertures ménagées sur la paroi latérale du boítier.Preferably, said outer side forming a push button extends flush with openings in the wall side of the case.

Avantageusement, ledit flanc extérieur formant bouton-poussoir comporte des cannelures.Advantageously, said external flank forming push button has grooves.

Selon une variante, ledit embout se prolonge vers le bas par une jupe sensiblement cylindrique pourvue à sa partie inférieure d'organes de fixation sur le boítier.According to a variant, said end piece extends downwards by a substantially cylindrical skirt provided at its lower part with organs fixing on the housing.

Selon une autre variante, ledit boítier est pourvu d'un jeu de deux ailettes diamétralement opposées.According to another variant, said housing is provided with a set of two diametrically opposite fins.

Avantageusement, l'extrémité libre dudit conduit est pourvue d'une buse de pulvérisation.Advantageously, the free end of said conduit is provided a spray nozzle.

De préférence, le conduit est raccordé audit tube par emmanchement avec serrage radial.Preferably, the conduit is connected to said tube by fitting with radial tightening.

Selon un premier mode de réalisation, le réservoir est immobilisé à l'intérieur du boítier tandis que ladite ailette est solidaire du tube et que ladite paroi inclinée est orientée vers le bas du conduit d'évacuation.According to a first embodiment, the reservoir is immobilized inside the housing while said fin is integral of the tube and that said inclined wall is oriented towards the bottom of the duct discharge.

Dans ce cas, ledit conduit d'évacuation est monté coulissant à l'intérieur de l'embout tandis que le réservoir est immobilisé dans un socle fixé de manière éventuellement amovible audit boítier.In this case, said exhaust duct is slidably mounted at inside the nozzle while the tank is immobilized in a base possibly fixed to said housing.

De préférence, ladite ailette est pourvue d'un bras de liaison formant entretoise avec ledit conduit.Preferably, said fin is provided with a link arm forming a spacer with said conduit.

En outre, ladite came est alors formée d'un bossage porté par le flanc intérieur de l'ailette.In addition, said cam is then formed of a boss carried by the inner flank of the fin.

Selon un second mode de réalisation, il est prévu que ladite ailette soit solidaire du réservoir qui est mobile axialement à l'intérieur du boítier tandis que ladite paroi inclinée est orientée vers le haut du conduit d'évacuation.According to a second embodiment, it is expected that said fin is integral with the tank which is axially movable inside of the housing while said inclined wall is oriented towards the top of the exhaust duct.

Dans ce cas, ledit conduit d'évacuation est monté fixe dans l'embout tandis que le réservoir coulisse dans un alésage interne au boítier.In this case, said exhaust duct is mounted fixed in the nozzle while the tank slides in an internal bore at the housing.

De préférence, ladite ailette est montée sur le col du réservoir au moyen d'une bague d'accrochage.Preferably, said fin is mounted on the neck of the tank by means of a hooking ring.

Avantageusement, ladite came est alors formée par le bord inférieur du flanc extérieur de l'ailette.Advantageously, said cam is then formed by the edge lower of the outer flank of the fin.

Au surplus, l'aspect esthétique d'ensemble est très attractif et donne l'apparence d'un conteneur traditionnel du type bouteille ou flacon.In addition, the overall aesthetic appearance is very attractive and gives the appearance of a traditional bottle type container or bottle.

L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels :

  • les figures 1a et 1b représentent des vues en coupe d'un premier mode de réalisation du distributeur de l'invention respectivement en position de repos et en phase de distribution ;
  • les figures 2a et 2b représentent des vues respectivement de face et en perspective du mode de réalisation des figures 1a et 1b ;
  • les figures 3a et 3b représentent des vues en coupe d'un second mode de réalisation du distributeur de l'invention respectivement en position de repos et en phase de distribution.
The invention will be better understood on reading the description which follows, accompanied by the drawings in which:
  • Figures 1a and 1b show sectional views of a first embodiment of the dispenser of the invention respectively in the rest position and in the dispensing phase;
  • Figures 2a and 2b show front and perspective views respectively of the embodiment of Figures 1a and 1b;
  • Figures 3a and 3b show sectional views of a second embodiment of the dispenser of the invention respectively in the rest position and in the dispensing phase.

Le distributeur représenté sur les figures est destiné à délivrer des doses successives d'un produit liquide contenu dans un réservoir.The dispenser shown in the figures is intended to deliver successive doses of a liquid product contained in a reservoir.

Comme représenté sur les figures 1a,1b, 3a et 3b, le distributeur est équipé, de manière traditionnelle, de moyens de prélèvement du produit qui sont constitués soit d'une pompe à précompression P montée ici sur le col d'un réservoir atmosphérique R soit d'une valve (non représentée) montée sur un réservoir sous pression.As shown in Figures 1a, 1b, 3a and 3b, the dispenser is traditionally equipped with means for sampling the product which consist of either a P precompression pump mounted here on the neck of an atmospheric tank R or a valve (not shown) mounted on a pressure tank.

Ces moyens de prélèvement sont susceptibles d'être actionnés par l'utilisateur qui, à cet effet, exerce un appui manuel sur un tube gicleur T alimenté par lesdits moyens de prélèvement et dont une partie d'extrémité fait saillie à l'extérieur du réservoir R en étant éventuellement coiffée par une tête de distribution (non représentée).These sampling means are likely to be activated by the user who, for this purpose, exerts manual pressure on a tube nozzle T supplied by said sampling means and part of which end protrudes outside the tank R being possibly capped by a dispensing head (not shown).

Cet appui peut également être exercé sur le fond du réservoir R par l'utilisateur en maintenant alors le tube T immobile, ce qui entraíne, dans tous les cas, un déplacement axial relatif du tube T en direction du réservoir R et la mise sous pression dudit réservoir.This support can also be exerted on the bottom of the tank R by the user while keeping the tube T stationary, which results, in all cases, a relative axial displacement of the tube T in the direction of the tank R and the pressurization of said tank.

L'ouverture du clapet de la pompe permet alors l'échappement du produit à l'extérieur via le tube T qui reprend ensuite sa position initiale sous l'action de moyens de rappel (non représentés).The opening of the pump valve allows the exhaust of the product outside via the tube T which then returns to its position initial under the action of return means (not shown).

Selon l'invention, la partie externe du tube gicleur T est raccordée de manière étanche à un conduit d'évacuation 1. Le raccordement est réalisé ici par emmanchement avec serrage radial du tube T dans le conduit 1. Le cas échéant, l'extrémité inférieure 1a du conduit 1 est pourvue d'un alésage approprié.According to the invention, the external part of the spray tube T is tightly connected to an exhaust duct 1. The connection is made here by fitting with radial clamping of the tube T in the conduit 1. If applicable, the lower end 1a of the conduit 1 is provided with an appropriate bore.

Le conduit d'évacuation 1 prolonge axialement le tube T en traversant un embout 2.The exhaust duct 1 axially extends the tube T by passing through a nozzle 2.

L'embout 2 est, par ailleurs, relié de manière rigide à un boítier B renfermant le réservoir R par des moyens qui seront décrits plus loin.The end piece 2 is, moreover, rigidly connected to a housing. B containing the reservoir R by means which will be described later.

Le réservoir R est, dans les modes de réalisation des figures, enfermé dans un boítier B délimité à sa partie supérieure par l'embout 2 et à sa partie inférieure par un socle 3 formant fond. Le boítier B est éventuellement amovible afin de permettre une recharge du boítier ou un remplissage dudit réservoir. The reservoir R is, in the embodiments of the figures, enclosed in a housing B delimited at its upper part by the end piece 2 and at its lower part by a base 3 forming the bottom. Box B is possibly removable to allow recharging of the case or filling said reservoir.

Sur les figures 1a et 1b, l'embout 2 se prolonge vers le bas par une jupe 2a sensiblement cylindrique pourvue, à sa partie inférieure, d'organes de fixation 23 destinés à coopérer avec des organes complémentaires 32 ménagés sur le socle 3 de façon à relier de manière rigide l'embout 2 au boítier B.In FIGS. 1a and 1b, the end piece 2 is extended downwards by a substantially cylindrical skirt 2a provided, at its lower part, fasteners 23 intended to cooperate with members complementary 32 formed on the base 3 so as to connect so rigid tip 2 to housing B.

La jupe 2a de l'embout 2 constitue en partie la paroi latérale du boítier B et peut être réalisée (figure 2b) d'une seule pièce avec l'embout 2 ou sous forme d'une pièce indépendante, destinée à être assemblée (figure 2a).The skirt 2a of the end piece 2 partially constitutes the side wall of the housing B and can be produced (FIG. 2b) in one piece with the end piece 2 or in the form of an independent part, intended to be assembled (Figure 2a).

L'extrémité supérieure 1b du conduit 1 est pourvue d'une buse de pulvérisation 10.The upper end 1b of the conduit 1 is provided with a nozzle spray 10.

Le distributeur de l'invention comporte au moins une, et ici, deux ailettes 11,12 diamétralement opposées.The dispenser of the invention has at least one, and here, two diametrically opposite fins 11, 12.

Les ailettes 11,12 sont pourvues chacune d'une came 110,120 destinée à coopérer par contact de glissement avec une paroi inclinée 21,22 solidaire de l'embout 2. Ces ailettes sont en prise soit avec le tube gicleur T comme dans le mode de réalisation des figures 1a et 1b, soit avec le réservoir R comme dans le mode de réalisation des figures 3a et 3b.The fins 11, 12 are each provided with a cam 110, 120 intended to cooperate by sliding contact with an inclined wall 21.22 secured to the end piece 2. These fins are engaged either with the tube nozzle T as in the embodiment of FIGS. 1a and 1b, ie with the reservoir R as in the embodiment of FIGS. 3a and 3b.

La longueur des parois inclinées 21,22 est ajustée en fonction de la course nécessaire au tube T pour permettre la délivrance d'une dose déterminée de produit. Le maintien de la position du boítier B et de l'embout 2 relativement au réservoir R ou au tube T est assuré par des moyens de fixation appropriés assurant une liaison rigide qui suffit à garantir la précision des doses de produit prélevées.The length of the inclined walls 21,22 is adjusted according to the stroke necessary for the tube T to allow the delivery of a dose determined product. Maintaining the position of the housing B and the nozzle 2 relative to the reservoir R or to the tube T is provided by suitable fixing means ensuring a rigid connection which is sufficient to guarantee the accuracy of the doses of product taken.

La coopération entre les cames 110,120 des ailettes 11,12 et les parois inclinées 21,22 de l'embout est telle qu'une poussée sensiblement radiale sur au moins l'une des ailettes provoque un glissement vers le bas ou vers le haut qui entraíne à son tour un rapprochement axial du tube T relativement au réservoir R. La course relative du tube T correspond à l'actionnement des moyens de prélèvement P conduisant à la délivrance d'une dose de produit.The cooperation between the cams 110,120 of the fins 11,12 and the inclined walls 21,22 of the nozzle is such that a thrust substantially radial on at least one of the fins causes a sliding towards the down or up which in turn causes an axial approximation of the tube T relative to reservoir R. The relative stroke of tube T corresponds to the actuation of the sampling means P leading to the delivery of a dose of product.

Sur la paroi latérale du boítier B sont ménagées des ouvertures 20 destinées à recevoir avec un léger jeu, les flancs extérieurs 11c, 12c des ailettes 11,12. On the side wall of the housing B are formed openings 20 intended to receive with a slight play, the outer sides 11c, 12c fins 11,12.

Les flancs extérieurs 11c,12c s'étendent dans les ouvertures 20 de façon affleurante à la paroi environnante de la jupe 2a pour ne pas créer de discontinuité sur le boítier et conserver son profil cylindroconique de révolution. Les bords des ouvertures 20 sont avantageusement biseautés.The outer sides 11c, 12c extend into the openings 20 flush with the surrounding wall of the skirt 2a so as not to create discontinuity on the case and keep its profile cylindroconical of revolution. The edges of the openings 20 are advantageously bevelled.

Les flancs extérieurs 11c, 12c forment des bouton-poussoirs et possèdent des génératrices qui sont au moins partiellement parallèles à celles du conduit 1.The outer sides 11c, 12c form push-buttons and have generators which are at least partially parallel to those of conduit 1.

De préférence, les faces apparentes des flancs 11c,12c sont pourvues de cannelures 13 pour faciliter l'appui manuel en évitant tout glissement.Preferably, the visible faces of the sides 11c, 12c are provided with grooves 13 to facilitate manual support avoiding all sliding.

Sur les figures 1a et 1b, les cames 110,120 sont réalisées sous forme de bossages portés par la partie supérieure des flancs intérieurs 11b,12b des ailettes 11,12 et les parois inclinées 21,22 sont orientées vers le bas du conduit 1.In FIGS. 1a and 1b, the cams 110, 120 are produced under form of bosses carried by the upper part of the inner flanks 11b, 12b of the fins 11,12 and the inclined walls 21,22 are oriented down the duct 1.

Dans ce cas, c'est avec la face inférieure des parois inclinées que les cames sont en contact de glissement.In this case, it is with the underside of the inclined walls that the cams are in sliding contact.

Les ailettes 11,12 sont rattachées au conduit 1 par des bras de liaison 11a,12a formant entretoises et qui s'étendent de façon sensiblement perpendiculaire à la paroi latérale dudit conduit.The fins 11, 12 are attached to the duct 1 by arms of link 11a, 12a forming spacers and which extend so substantially perpendicular to the side wall of said conduit.

Le cas échéant, ces bras de liaison sont intégrés dans un disque monté coaxialement sur le conduit 1.If necessary, these link arms are integrated into a disc coaxially mounted on duct 1.

Les flancs intérieurs 11b,12b prolongent les bras 11a,12a vers le haut en s'éloignant radialement du conduit 1 et assurent la liaison avec les flancs extérieurs 11c,12c.The inner sides 11b, 12b extend the arms 11a, 12a towards the high away radially from the duct 1 and provide the connection with the outer sides 11c, 12c.

Les flancs intérieurs 11b,12b sont pourvus de raidisseurs sous forme de nervures 111,112 qui permettent, toutefois, de conserver une certaine souplesse en déformation.The inner sides 11b, 12b are provided with stiffeners under ribs 111,112 which allow, however, to maintain a some flexibility in deformation.

Le conduit 1 coulisse ici librement à l'intérieur d'un alésage axial ménagé dans l'embout plein 2 tandis que le réservoir R est immobilisé à l'intérieur du boítier B.The conduit 1 slides here freely inside a bore axial formed in the full nozzle 2 while the reservoir R is immobilized inside the housing B.

L'extrémité supérieure 1b du conduit 1 fait ici saillie librement à l'extérieur de l'embout 2 au moins en position de repos du distributeur.The upper end 1b of the conduit 1 projects here freely at the outside of the nozzle 2 at least in the distributor's rest position.

Le socle 3 comporte une cavité cylindrique 30 destinée à recevoir le réservoir R et dont les dimensions sont ajustées à cet effet en vue d'assurer son calage par serrage radial. The base 3 comprises a cylindrical cavity 30 intended for receive the tank R and whose dimensions are adjusted for this purpose by view of securing it by radial tightening.

Pour faciliter l'introduction du réservoir R dans le socle 3, la cavité 30 est pourvue d'un alésage supérieur tronconique 31.To facilitate the introduction of the reservoir R into the base 3, the cavity 30 is provided with a frustoconical upper bore 31.

Sur les figures 3a et 3b, les ailettes 11,12 sont solidaires du réservoir R qui est ici mobile axialement à l'intérieur du boítier B tandis que le conduit d'évacuation 1 est monté fixe dans l'embout 2 en faisant saillie vers le bas.In FIGS. 3a and 3b, the fins 11, 12 are integral with the tank R which is here axially movable inside the housing B while that the exhaust duct 1 is fixedly mounted in the end piece 2 by making protruding downwards.

Le réservoir R coulisse axialement et de façon guidée dans un alésage interne 32 ménagé dans le socle 3 tandis que les flancs intérieurs 11b, 12b subissent une flexion vers l'axe du conduit 10 sous l'effet de la poussée radiale sur les ailettes 11,12 dont les flancs extérieurs 11c,12c viennent alors se loger à l'intérieur de l'embout 2.The reservoir R slides axially and guided in a internal bore 32 formed in the base 3 while the sides interiors 11b, 12b are bent towards the axis of the conduit 10 under the effect of the radial thrust on the fins 11,12 whose flanks 11c, 12c are then housed inside the nozzle 2.

Les parois inclinées 21,22 sont orientées vers le haut du conduit 1 et coopèrent, toujours par glissement, avec le bord inférieur des flancs extérieurs 11c,12c, formant came des ailettes 11,12.The inclined walls 21, 22 are oriented towards the top of the duct 1 and cooperate, still by sliding, with the lower edge of the sides 11c, 12c, forming a cam of the fins 11,12.

A cet effet, le bord inférieur des flancs 11c,12c a un profil curviligne et dans ce cas, c'est alors avec la face supérieure des parois inclinées 21,22 que les cames sont en contact de glissement.For this purpose, the lower edge of the sides 11c, 12c has a profile curvilinear and in this case, it is then with the upper face of the walls inclined 21,22 that the cams are in sliding contact.

Chacune des parois inclinées 21,22 est réalisée en une portion de plan portée par un cône disposé entre la paroi latérale interne du boítier B et l'embout 2 en étant, le cas échéant, solidaire de la partie inférieure dudit embout.Each of the inclined walls 21, 22 is made in one portion in plan carried by a cone disposed between the internal lateral wall of the housing B and the end piece 2 being, where appropriate, integral with the part lower of said tip.

Les faces de contact des parois inclinées 21,22 présentent éventuellement, une pente variable sur leur hauteur, de façon discontinue ou continue (définissant alors une courbure) en offrant, par exemple, une pente plus faible dans leur partie basse correspondant au début de la poussée sur les ailettes 11,12.The contact faces of the inclined walls 21, 22 have possibly a variable slope on their height, so discontinuous or continuous (then defining a curvature) by offering, by example, a lower slope in their lower part corresponding to the start of thrust on the fins 11,12.

Les ailettes 11,12 sont montées sur le col du réservoir R au moyen d'une bague 121 solidaire des flancs intérieurs 11b,12b et solidaire des flancs intérieurs 11b,12b et équipée, par exemple, d'organes d'encliquetage destinés à coopérer avec des organes complémentaires portés par le col du réservoir R ou par une douille D assurant, par ailleurs, le verrouillage des moyens de prélèvement P.The fins 11, 12 are mounted on the neck of the tank R at by means of a ring 121 integral with the inner sides 11b, 12b and integral with the inner sides 11b, 12b and equipped, for example, latching members intended to cooperate with members worn by the neck of the tank R or by a socket D ensuring, moreover, the locking of the sampling means P.
