Description

L'invention concerne un distributeur double pour produits fluides du type comprenant, dans un boítier commun, deux enceintes emplies de fluides différents et fermées chacune par une pompe munie d'une valve, les deux valves étant actionnées par un poussoir commun, ledit poussoir étant muni d'une chambre dans laquelle débouchent les sorties des deux valves et qui comporte un orifice de sortie du mélange des fluides.The invention relates to a double dispenser for products. fluids of the type comprising, in a common housing, two enclosures filled with different fluids and closed each by a pump fitted with a valve, the two valves being actuated by a common pusher, said pusher being provided a bedroom into which the outlets of the two valves and which has an outlet for mixing the fluids.

Ces distributeurs sont en général utilisés pour des produits cosmétiques crémeux, pâteux ou liquides et présentent l'avantage que le mélange des produits fluides a lieu préalablement à l'expulsion, de sorte que le produit mixte présente l'aspect d'un produit unique à la sortie.These dispensers are generally used for products creamy, pasty or liquid cosmetics and have the advantage that the mixing of the fluid products takes place prior to expulsion, so that the mixed product presents the appearance of a unique product at the outlet.

La plupart de ces distributeurs présentent cependant l'inconvénient que la chambre de mélange est à l'air ambiant et que le mélange qui y reste après une expulsion et jusqu'à une expulsion suivante est soumis à une oxydation qui est déjà nuisible pour des produits purs mais qui, dans le cas du mélange de deux produits purs, peut induire des réactions chimiques entre les composants. Most of these distributors, however, the downside that the mixing chamber is in ambient air and that the mixture which remains there after an expulsion and until a subsequent expulsion is subjected to an oxidation which is already harmful for pure products but which, in the case of mixture of two pure products, can cause reactions between components.

On connaít par FR-A-2.650.562, un distributeur double comportant un orifice de sortie des produits, étanche à l'air hors de la distribution, mais dans lequel les deux produits sont expulsés par l'intermédiaire de deux canaux parallèles jusqu'à la sortie et par conséquent sans mélange desdits produits.We know by FR-A-2.650.562, a double distributor having an airtight product outlet out of distribution but in which both products are expelled through two parallel channels up to the exit and therefore without mixing of said products.

On connaít également par EP-A-0.598.637 appartenant à la titulaire un distributeur-mélangeur à dosage variable ayant les caractéristiques du préambule de la revendication 1 et permettant la distribution d'un mélange des produits dans des proportions différentes. Ce distributeur possède une soupape de sortie étanche à l'air, au niveau de laquelle intervient le mélange des produits. Cependant, bien que l'étanchéité soit réalisée à l'intérieur de la chambre de mélange évitant ainsi une oxydation des produits, une dégradation de ces produits liée à l'instabilité du mélange peut intervenir et entraíner par la suite une pollution lors des distributions ultérieures.We also know by EP-A-0.598.637 belonging to the holds a variable-dose distributor-mixer having the features of the preamble of claim 1 and allowing the distribution of a mixture of products in different proportions. This dispenser has a valve airtight outlet, at which level intervenes mixing products. However, although the tightness either made inside the mixing chamber avoiding thus an oxidation of the products, a degradation of these products linked to the instability of the mixture can intervene and subsequently cause pollution during distributions later.

La présente invention vise à pallier ces inconvénients des pompes connues.The present invention aims to overcome these drawbacks of known pumps.

A cet effet, le distributeur selon l'invention comprend dans un boitier commun, deux enceintes emplies de fluides différents et fermées chacune par une pompe munie d'une valve, les deux valves étant actionnées par un poussoir commun, ledit poussoir étant muni d'une chambre dans laquelle débouchent les sorties des deux valves, ladite chambre étant divisée par une paroi de manière à former deux chambres séparées dans lesquelles débouchent respectivement les sorties des deux valves, ladite paroi comportant deux orifices de sortie reliés respectivement auxdites chambres séparées, lesdits orifices de sortie débouchant respectivement dans les cavités d'une pièce de diffusion en matériau élastiquement déformable, ladite pièce de diffusion comportant une fente de sortie fermée de manière étanche par deux lèvres agencées pour s'écarter sous la pression du fluide arrivant respectivement dans les cavités lors de l'enfoncement du poussoir, caractérisée en ce que la pièce de diffusion comporte une cloison médiane séparant les cavités, la cloison médiane étant réalisée d'une seule pièce avec le bec de diffusion.To this end, the dispenser according to the invention comprises in a common box, two enclosures filled with fluids different and each closed by a pump fitted with a valve, the two valves being actuated by a pusher common, said pusher being provided with a chamber in which open the outlets of the two valves, said chamber being divided by a wall so as to form two chambers separated into which the outputs of the two valves, said wall comprising two outlet ports connected respectively to said chambers separate, said outlet openings respectively in the cavities of a diffusion piece in elastically deformable material, said diffusion piece having an outlet slot closed in a sealed manner by two lips arranged to move apart under the pressure of the fluid arriving respectively in the cavities during depression of the pusher, characterized in that the piece of diffusion has a middle partition separating the cavities, the middle partition being made in one piece with the diffusion nozzle.

Avec le distributeur selon l'invention, le mélange des deux fluides ne se fait plus avant l'expulsion mais au moment même de cette expulsion, lors du passage à travers la fente de sortie, de sorte que les fluides restant dans les différents canaux après une distribution de produit mixte sont à l'abri de l'air.With the dispenser according to the invention, the mixture of the two fluids is no longer done before expulsion but at the same time of this expulsion, when passing through the slot of outlet, so that the fluids remaining in the different channels after a mixed product distribution are immune air.

La paroi est réalisée solidaire du poussoir et en particulier elle peut être ajustée et soudée à celui-ci.The wall is made integral with the pusher and in particular it can be adjusted and welded to it.

Elle s'étend également de manière avantageuse depuis la chambre qu'elle divise en deux chambres séparées jusqu'à la cavité de la pièce de diffusion de sorte que le mélange des deux fluides n'intervient qu'au moment de l'expulsion des fluides. Ainsi, dans le cas de deux fluides qui ne sont pas suffisamment stables mélangés l'un à l'autre, le distributeur double selon l'invention permet une préservation séparée des deux fluides évitant ainsi tous risques d'une quelconque perte d'efficacité des fluides.It also extends advantageously from the room which it divides into two separate rooms up to the cavity of the diffusion piece so that the mixture of two fluids only intervene when the expulsion of fluids. So, in the case of two fluids that are not sufficiently stable mixed together, the distributor double according to the invention allows separate preservation of two fluids thus avoiding all risks of any kind loss of fluid efficiency.

On décrira maintenant l'invention plus en détails à l'aide des dessins annexés dans lesquels les figures représentent :

  • la figure 1 est une vue en coupe longitudinale d'un distributeur selon l'exemple de réalisation de l'invention présentant deux réservoirs;
  • la figure 2 est une vue en coupe II-II du distributeur selon la figure 1;
  • la figure 3 est une coupe selon III-III du distributeur selon la figure 1;
  • la figure 4 représente une vue en coupe latérale de l'extrémité supérieure du distributeur selon l'invention;
  • la figure 5 représente une vue en coupe latérale du distributeur selon la figure 3.
    • The invention will now be described in more detail with the aid of the appended drawings in which the figures represent:
  • Figure 1 is a longitudinal sectional view of a dispenser according to the embodiment of the invention having two tanks;
  • Figure 2 is a sectional view II-II of the dispenser according to Figure 1;
  • Figure 3 is a section on III-III of the dispenser according to Figure 1;
  • Figure 4 shows a side sectional view of the upper end of the dispenser according to the invention;
  • FIG. 5 represents a side section view of the dispenser according to FIG. 3.

    • Le distributeur double comprend un boítier 1 contenant deux réservoirs 2 totalement indépendants l'un de l'autre et pouvant renfermer des fluides différents; chaque réservoir 2 est muni d'une pompe 3 pourvue d'une valve actionnée simultanément avec l'autre valve par un poussoir commun 5.The double distributor includes a box 1 containing two tanks 2 completely independent of each other and which may contain different fluids; each tank 2 is fitted with a pump 3 provided with an actuated valve simultaneously with the other valve by a common pusher 5.

    Une pièce de diffusion ou bec 11 est monté sur ledit poussoir commun 5 et présente une fente de sortie formant deux lèvres de distribution qui sont prévues pour pouvoir s'écarter élastiquement l'une de l'autre sous la pression du fluide mixte à distribuer.A diffusion piece or spout 11 is mounted on said pusher common 5 and has an outlet slot forming two lips of distribution which are planned to be able to deviate resiliently from each other under fluid pressure mixed to distribute.

    La pièce de diffusion est en matériau élastiquement déformable et à cet effet est constituée par injection d'une matière thermoplastique ayant des propriétés d'élasticité propres à assurer la déformation élastique des lèvres de la fente de sortie du bec 11.The diffusion piece is made of elastic material deformable and for this purpose is constituted by injection of a thermoplastic material having elasticity properties suitable for ensuring the elastic deformation of the lips of the nozzle outlet slot 11.

    Les lèvres assurent que le produit restant à l'intérieur du bec 11 est à l'abri de l'air et donc de toute oxydation.The lips ensure that the product remaining inside the spout 11 is sheltered from air and therefore from any oxidation.

    Selon l'invention, les sorties des valves des pompes 3 arrivent dans une chambre 6 du poussoir commun 5 garnie d'une paroi 7 scindant ladite chambre 6 en deux chambres 6' et 6'' accueillant les fluides respectifs. Ainsi, lors d'une pression exercée sur le poussoir commun 5, les deux fluides différents sont amenés de manière séparée aux chambres 6' et 6''. According to the invention, the outputs of the valves of the pumps 3 arrive in a room 6 of the common pusher 5 furnished with a wall 7 dividing said chamber 6 into two chambers 6 'and 6' ' accommodating the respective fluids. So during a pressure exerted on the common pusher 5, the two fluids are brought separately to rooms 6 'and 6 ''.

    La paroi 7 de la chambre 6 est réalisée de préférence de manière à présenter deux orifices de sortie 8' et 8'' correspondants respectivement aux chambres 6' et 6'' et conduisant les fluides séparément dans les cavités 10' et 10'' respectivement du bec de diffusion d'où les deux fluides sont expulsés sous forme d'un fluide mixte par la seule et même fente de sortie 12. Les cavités 10' et 10'' sont séparées par une cloison médiane 14 d'une seule pièce avec le bec de diffusion.The wall 7 of the chamber 6 is preferably made of so as to present two outlet ports 8 'and 8' ' corresponding to rooms 6 'and 6' 'and conducting the fluids separately in the cavities 10 'and 10 '' respectively from the diffusion nozzle where the two fluids are expelled as a mixed fluid by the single and same outlet slot 12. The 10 'and 10' 'cavities are separated by a central partition 14 in one piece with the diffusion nozzle.
