Description

La présente invention concerne un organe de distribution pour la pulvérisation simultanée de deux produits et un dispositif de conditionnement équipé d'un tel organe de distribution.The present invention relates to a dispensing member for the simultaneous spraying of two products and a packaging device equipped with such a dispensing member.

On connaît déjà des dispositifs qui permettent de conditionner séparément deux produits dans des récipients sous pression, par exemple du type distributeur aérosol, et de les mélanger extemporanément pour en obtenir un troisième qui est généralement instable mais permet d'obtenir l'effet recherché.Devices are already known which make it possible to condition two products separately in pressurized containers, for example of the aerosol dispenser type, and to mix them extemporaneously to obtain a third which is generally unstable but makes it possible to obtain the desired effect.

La société déposante a décrit dans FR-A-2 598 392 un dispositif qui comporte un organe de distribution muni d'une embase coiffant la partie supérieure de deux récipients accolés, équipés chacun d'une valve actionnée par une tige de poussée, une zone d'actionnement de l'organe de distribution permettant l'enfoncement simultané des tiges des deux valves, chacune des valves débouchant dans un canal relié à une buse, les deux buses étant agencées concentriquement l'une par rapport à l'autre, de manière à pulvériser simultanément les deux produits, à l'intérieur d'un même cône de distribution.The applicant company described in FR-A-2 598 392 a device which comprises a dispensing member provided with a base covering the upper part of two adjoining containers, each equipped with a valve actuated by a push rod, an area actuating the dispensing member allowing the simultaneous insertion of the rods of the two valves, each of the valves opening into a channel connected to a nozzle, the two nozzles being arranged concentrically with respect to each other, so spraying the two products simultaneously, inside the same distribution cone.

Un tel dispositif est avantageux, du fait que le recours à deux buses concentriques permet d'obtenir un mélange des produits, au moment même de leur pulvérisation.Such a device is advantageous, because the use of two concentric nozzles makes it possible to obtain a mixture of the products, at the very moment of their spraying.

Cependant, un tel dispositif révèle, à l'usage, un certain nombre d'inconvénients.However, such a device reveals, in use, a certain number of drawbacks.

D'une part, la proximité des deux buses fait que les deux produits se mélangent généralement au voisinage immédiat des buses, le troisième produit, qui résulte de ce mélange, pouvant alors s'accumuler à la sortie des buses et gêner leur fonctionnement.On the one hand, the proximity of the two nozzles means that the two products generally mix in the immediate vicinity of the nozzles, the third product, which results from this mixture, which can then accumulate at the outlet of the nozzles and interfere with their operation.

D'autre part, on constate que le mélange des deux produits à l'intérieur du cône de distribution ne s'effectue pas de manière suffisamment homogène, l'un des produits étant fortement concentré dans la partie centrale du cône de distribution, tandis que l'autre produit se situe majoritairement à la périphérie dudit cône de distribution.On the other hand, it can be seen that the mixing of the two products inside the distribution cone is not carried out in a sufficiently homogeneous manner, one of the products being highly concentrated in the central part of the distribution cone, while the other product is mainly located at the periphery of said distribution cone.

On connaît par ailleurs par FR-A-1 413 184 un organe de distribution permettant de projeter simultanément ou non des produits contenus dans des récipients séparés. L'organe de distribution comporte deux canaux débouchant à proximité l'un de l'autre sur la face avant de l'organe de distribution. Le dispositif connu ne comporte pas de buses de pulvérisation et ne permet pas de projeter les produits sous forme de fines gouttelettes et donc ne permet pas d'obtenir un mélange pulvérisé sous forme homogène.FR-A-1 413 184 also discloses a distribution member making it possible to project products simultaneously or not contained in separate containers. The dispensing member has two channels opening close to each other on the front face of the dispensing member. The known device does not have spray nozzles and does not make it possible to spray the products in the form of fine droplets and therefore does not make it possible to obtain a spray mixture in homogeneous form.

On connait par EP-0 313 414 un dispositif de conditionnement séparé d'au moins deux produits à pulvériser simultanément, comportant deux bombes aérosol accolées, et un levier prenant appui dans la région médiane d'une plaque d'entraînement des boutons-poussoir des bombes aérosol.EP-0 313 414 discloses a separate packaging device for at least two products to be sprayed simultaneously, comprising two attached aerosol cans, and a lever bearing in the median region of a push-button drive plate. aerosol cans.

Les buses des boutons-poussoir sont orientées dans des directions convergentes.The nozzles of the push buttons are oriented in converging directions.

Un tel dispositif, outre son coût de fabrication relativement élevé, présente l'inconvénient qu'en cas de résistance différente à l'enfoncement des boutons-poussoir des deux bombes aérosol, l'enfoncement sur une faible course du levier peut s'avérer insuffisant pour provoquer la distribution simultanée des produits contenus dans les deux bombes aérosol.Such a device, in addition to its relatively high manufacturing cost, has the disadvantage that in the event of different resistance to the depressing of the push buttons of the two aerosol cans, depressing on a short stroke of the lever may prove to be insufficient. to cause the simultaneous distribution of the products contained in the two aerosol cans.

La présente invention vise à fournir un organe de distribution qui permet d'obtenir un mélange homogène des deux produits lors de leur pulvérisation, sans notamment présenter les inconvénients rappelés ci-dessus.The present invention aims to provide a distribution member which makes it possible to obtain a homogeneous mixture of the two products during their spraying, without in particular exhibiting the drawbacks mentioned above.

La présente invention a pour objet un organe de distribution pour la pulvérisation simultanée de deux produits contenus dans deux récipients respectifs accolés, ledit organe de distribution étant assujetti à la partie supérieure des deux récipients et comprenant, pour chaque récipient, un canal d'amenée de produit et une buse de pulvérisation du produit, les deux buses étant disposées l'une à côté de l'autre et orientées selon des directions convergentes, caractérisé par le fait qu'il comporte une embase à fixer sur les récipients et une partie mobile articulée sur l'embase , réalisée d'un seul tenant avec cette dernière, dans laquelle sont ménagés lesdits canaux d'amenée de produit et portant lesdites buses.The subject of the present invention is a dispensing member for simultaneously spraying two products contained in two respective adjoining containers, said dispensing member being secured to the upper part of the two containers and comprising, for each container, a supply channel for product and a product spray nozzle, the two nozzles being arranged one next to the other and oriented in converging directions, characterized in that it comprises a base to be fixed on the containers and a movable articulated part on the base, made in one piece with the latter, in which are formed said product supply channels and carrying said nozzles.

On comprend que l'organe de distribution selon l'invention permet de pulvériser simultanément deux produits à partir de deux buses qui, d'une part, sont suffisamment espacées l'une de l'autre pour que le mélange des deux produits ne puisse pas avoir lieu au voisinage immédiat des buses et, d'autre part, sont orientées de façon convergente de sorte que les deux cônes de distribution de produits issus chacun d'une buse se rencontrent pour former un volume de distribution de section sensiblement ovoïdale, à l'intérieur duquel les deux produits se mélangent de façon homogène.It is understood that the dispensing member according to the invention makes it possible to spray two products simultaneously from two nozzles which, on the one hand, are sufficiently spaced from one another so that the mixing of the two products cannot take place in the immediate vicinity of the nozzles and, on the other hand, are oriented in a convergent manner so that the two product distribution cones each coming from a nozzle meet to form a distribution volume of substantially ovoid cross section, inside which the two products mix homogeneously.

En effet, contre toute attente, les deux produits se mélangent de façon homogène dans le volume de distribution résultant de l'intersection des deux cônes de distribution alors qu'intuitivement, cette intersection des deux cônes devrait plutôt comporter une partie centrale dans laquelle le mélange serait assez homogène et au moins deux parties périphériques dans lesquelles l'un des produits serait plus fortement concentré que l'autre.Contrary to all expectations, the two products mix homogeneously in the volume of distribution resulting from the intersection of the two distribution cones whereas intuitively, this intersection of the two cones should rather have a central part in which the mixture would be fairly homogeneous and at least two peripheral parts in which one of the products would be more highly concentrated than the other.

Dans une réalisation particulière de l'invention, ladite partie mobile est articulée sur l'embase au moyen d'une charnière allongée formée par une bande mince.In a particular embodiment of the invention, said movable part is articulated on the base by means of an elongated hinge formed by a thin strip.

L'organe de distribution selon l'invention est particulièrement indiqué pour pulvériser des produits cosmétiques ou des produits coiffants, conditionnés dans des récipients préssurisés.The dispensing member according to the invention is particularly suitable for spraying cosmetic products or styling products, packaged in pressurized containers.

Il présente en outre l'avantage de pouvoir être facilement réalisé d'un seul tenant par moulage d'une matière plastique, seules les buses étant réalisées séparément puis mises en place, et de permettre la distribution simultanée des produits contenus dans les récipients, même si les valves des récipients présentent des résistances différentes à l'actionnement.It also has the advantage of being able to be easily produced in one piece by molding a plastic material, only the nozzles being produced separately and then put in place, and allowing the simultaneous distribution of the products contained in the containers, even if the valves of the receptacles have different resistance to actuation.

Conformément à l'invention, l'écartement des deux buses est important par rapport au diamètre de ces dernières. Il est déterminé de manière à ce que les deux cônes de distribution se rencontrent à une certaine distance desdites buses, compte-tenu par ailleurs des directions convergentes des cônes de distribution et de leurs angles d'ouverture.According to the invention, the spacing of the two nozzles is large relative to the diameter of the latter. It is determined so that the two distribution cones meet at a certain distance from said nozzles, taking into account, moreover, the converging directions of the distribution cones and their opening angles.

La présente invention a également pour objet un dispositif de conditionnement séparé d'au moins deux produits à pulvériser simultanément comportant deux récipients munis chacun d'une valve, qui est caractérisé par le fait qu'il comporte un organe de distribution tel que décrit ci-dessus.The present invention also relates to a separate packaging device for at least two products to be sprayed simultaneously comprising two containers each provided with a valve, which is characterized in that it comprises a dispensing member as described below. above.

Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant un mode de réalisation donné à titre d'exemple non limitatif en référence au dessin annexé dans lequel :

  • la figure 1 est une vue en élévation d'un dispositif de conditionnement selon un mode de réalisation de l'invention,
  • la figure 2 est une vue de dessus de la figure 1,
  • la figure 3 est une vue en coupe selon III-III de la figure 2,
  • la figure 4 est une vue en coupe selon IV-IV de la figure 2,
  • la figure 5 est une vue analogue à la figure 2 représentant le dispositif en cours de fonctionnement, et
  • la figure 6 représente en vue de dessus, l'organe de pulvérisation juste après son moulage.
In order to better understand the invention, we will now describe an embodiment given by way of non-limiting example with reference to the accompanying drawing in which:
  • FIG. 1 is an elevation view of a packaging device according to an embodiment of the invention,
  • FIG. 2 is a top view of FIG. 1,
  • FIG. 3 is a sectional view along III-III of FIG. 2,
  • FIG. 4 is a sectional view along IV-IV of FIG. 2,
  • FIG. 5 is a view similar to FIG. 2 showing the device during operation, and
  • Figure 6 shows a top view, the spray member just after molding.

Le dispositif représenté sur le dessin comporte deux récipients identiques 1 du type bombe aérosol. Chaque récipient 1 est muni, à sa partie supérieure, d'une valve 2 dont la tige 3 est mobile dans l'axe 4 du récipient.The device shown in the drawing comprises two identical containers 1 of the aerosol can type. Each container 1 is provided, at its upper part, with a valve 2, the rod 3 of which is movable in the axis 4 of the container.

Les deux récipients 1 sont accolés l'un contre l'autre avec leurs axes 4, et donc leurs tiges 3 de valves, parallèles.The two containers 1 are placed against one another with their axes 4, and therefore their valve stems 3, parallel.

Un organe de distribution 5 selon l'invention en matière plastique est monté à la partie supérieure des deux récipients 1 accolés.A dispensing member 5 according to the invention in plastic material is mounted at the upper part of the two adjoining containers 1.

Cet organe de distribution 5 comporte une embase fixe 6 qui coiffe la valve 2 des deux récipients 1 et une partie mobile 7, articulée sur l'embase 6 autour d'une charnière 8 formée par une bande mince de matière plastique venue d'un seul tenant avec l'embase 6 et la partie mobile 7.This dispensing member 5 comprises a fixed base 6 which covers the valve 2 of the two containers 1 and a movable part 7, articulated on the base 6 around a hinge 8 formed by a thin strip of plastic material coming from a single holding with the base 6 and the mobile part 7.

L'embase 6 est retenue par encliquetage sur les valves 2 au moyen d'une nervure 9 prévue à la partie inférieure de sa face dirigée vers les valves 2, comme on le voit sur la figure 1.The base 6 is retained by snap-fastening on the valves 2 by means of a rib 9 provided at the lower part of its face directed towards the valves 2, as seen in FIG. 1.

On voit, sur la figure 2, que la nervure 9 enserre chaque valve 2 sur plus de la moitié de son périmètre, de sorte que l'accrochage ainsi obtenu suffit à maintenir les deux récipients 1 accolés l'un contre l'autre.It can be seen, in FIG. 2, that the rib 9 encloses each valve 2 over more than half of its perimeter, so that the attachment thus obtained is sufficient to keep the two containers 1 placed against each other.

La partie mobile 7 de l'organe de distribution comporte, en face de chaque valve 2, une tubulure 10 dont l'extrémité située du côté de la valve 2 coopère avec la tige 3 de valve.The movable part 7 of the dispensing member comprises, opposite each valve 2, a tube 10 whose end located on the side of the valve 2 cooperates with the valve stem 3.

La tubulure 10 peut s'appuyer sur la tige 3 pour la repousser vers l'intérieur du récipient tandis que le conduit intérieur 11 de la tubulure 10 communique avec celui de la tige 3 de valve.The tubing 10 can rest on the rod 3 to push it towards the interior of the container while the inner conduit 11 of the tubing 10 communicates with that of the valve rod 3.

Comme on le voit sur la figure 4, le conduit intérieur 11 de chaque tubulure 10 s'étend jusqu'au voisinage de la paroi supérieure 12 de la partie mobile 7 de l'organe de distribution, où ledit conduit intérieur communique avec un canal 13 d'amenée de produit qui s'étend perpendiculairement à l'axe 4 du récipient, jusqu'à une paroi latérale 14 de l'organe de distribution, désignée paroi frontale.As seen in Figure 4, the inner conduit 11 of each tube 10 extends to the vicinity of the upper wall 12 of the movable part 7 of the dispensing member, where said inner conduit communicates with a channel 13 product supply which extends perpendicular to the axis 4 of the container, to a side wall 14 of the dispensing member, designated front wall.

Les deux canaux 13 d'amenée de produit sont dirigés de façon convergente, le point d'intersection P de leurs axes 15 se trouvant sensiblement dans le plan de symétrie du dispositif.The two product supply channels 13 are directed in a convergent manner, the point of intersection P of their axes 15 lying substantially in the plane of symmetry of the device.

Des zones de réception de buses, également désignées center-post, sont prévues à l'extrémité des canaux débouchant vers l'extérieur.Nozzles reception areas, also called center-post, are provided at the end of the channels opening outwards.

Chaque center-post se présente sous la forme d'un moyeu cylindrique 16 autour duquel est ménagé un espace annulaire 17, dans lequel débouche le canal 13 correspondant, destiné à recevoir une valve conventionnelle (non représentée) de forme cylindrique et ouverte à l'une de ses extrémités.Each center-post is in the form of a cylindrical hub 16 around which is formed an annular space 17, into which the corresponding channel 13 opens, intended to receive a conventional valve (not shown) of cylindrical shape and open to the one of its ends.

Chaque center-post 16 est situé sur la face frontale 14 de l'organe de distribution, au fond d'un dégagement cylindrique 18.Each center-post 16 is located on the front face 14 of the dispensing member, at the bottom of a cylindrical clearance 18.

L'écartement des center-post 16 est assez important par rapport au diamètre des buses.The spacing of the center-post 16 is quite large compared to the diameter of the nozzles.

A l'opposé de sa face frontale 14, la partie mobile 7 de l'organe de distribution comporte une zone d'actionnement 20 qui permet à un utilisateur d'exercer une force pour enfoncer cette partie mobile 7 de l'organe de distribution en direction des récipients 1, afin d'actionner les valves et provoquer la pulvérisation simultanée des deux produits, même si la partie mobile n'est pas enfoncée à fond.Opposite its front face 14, the movable part 7 of the dispensing member has an actuation zone 20 which allows a user to exert a force to push this movable portion 7 of the dispensing member into direction of the receptacles 1, in order to actuate the valves and cause the simultaneous spraying of the two products, even if the movable part is not fully depressed.

On comprend que, grâce à la charnière allongée 8, la partie mobile 7 de l'organe de distribution ne dispose que d'un seul degré de liberté, qui est sa rotation autour de ladite charnière, de sorte que, même en cas de résistances différentes des valves 2, l'action d'un utilisateur sur la zone d'actionnement 20 provoque un déplacement identique des deux tiges 3 de valves.It is understood that, thanks to the elongated hinge 8, the movable part 7 of the dispensing member has only one degree of freedom, which is its rotation around said hinge, so that, even in the event of resistance Different from the valves 2, the action of a user on the actuation zone 20 causes identical displacement of the two valve stems 3.

La figure 5 représente, en vue de dessus, l'organe de distribution en cours de fonctionnement, muni de buses 16a dont une seule a été représentée.Figure 5 shows, in top view, the dispensing member during operation, provided with nozzles 16 a of which only one has been shown.

On voit que deux cônes de distribution, 21 issus chacun d'une buse 16a, se rencontrent à une certaine distance des buses pour ne former qu'un seul volume de distribution 22 de section sensiblement ovoïdale.It can be seen that two distribution cones, 21 each coming from a nozzle 16 a , meet at a certain distance from the nozzles so as to form only one distribution volume 22 of substantially ovoid section.

A l'intérieur de ce volume de distribution commun 22, les deux produits se mélangent de façon homogène.Within this common distribution volume 22, the two products mix homogeneously.

On peut noter en outre que le fait que le mélange ne se produise qu'à une certaine distance des buses préserve ces dernières de tout risque de colmatage pouvant résulter d'une réaction chimique d'un produit avec l'autre.It may further be noted that the fact that the mixing only occurs at a certain distance from the nozzles protects the latter from any risk of clogging which may result from a chemical reaction of one product with the other.

On peut noter également que la section du volume de distribution commun 22 n'est pas significativement supérieure à celle de l'un des cônes de distribution 21, pris séparément.It can also be noted that the section of the common distribution volume 22 is not significantly greater than that of one of the distribution cones 21, taken separately.

Sur la figure 6, on a représenté l'organe de distribution 5 en cours de réalisation, à sa sortie de moule.In Figure 6, there is shown the dispensing member 5 in progress, at its mold outlet.

Des tiges de moulage 23, présentes dans la partie mobile 7 de l'organe de distribution 5, réservent l'espace des canaux 13 d'amenée de produit qui s'étendent depuis les conduits intérieurs 11 des tubulures 10 jusqu'aux center-post 16.Molding rods 23, present in the movable part 7 of the dispensing member 5, reserve the space of the product supply channels 13 which extend from the inner conduits 11 of the pipes 10 to the center-post 16.

On voit, que, grâce à la disposition coaxiale de chaque canal 13 d'amenée de produit avec le center-post 16 correspondant, l'extraction de chaque tige de moulage 23 peut s'effectuer sans difficulté.It can be seen that, thanks to the coaxial arrangement of each product supply channel 13 with the corresponding center-post 16, the extraction of each molding rod 23 can be carried out without difficulty.

Il en résulte que l'organe de distribution selon l'invention, y compris les center-post destinés à recevoir les buses, peut être facilement moulé d'un seul tenant, seules les buses de pulvérisation devant être rapportées pour être logées dans les center-post.As a result, the distribution member according to the invention, including the center-post intended to receive the nozzles, can be easily molded in one piece, only the spray nozzles having to be attached to be housed in the centers. -post.

Il est bien entendu que le mode de réalisation qui vient d'être décrit ne présente aucun caractère limitatif et qu'il pourra recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiment which has just been described has no limiting character and that it can receive any desirable modifications without departing from the scope of the invention.
