Description

L'invention concerne un bouton poussoir d'actionnement d'un système de distribution d'un liquide ainsi qu'un tel système de distribution.The invention relates to a push button for actuating a liquid distribution system and such a dispensing system.

Dans une application particulière, le système de distribution est destiné à équiper des flacons utilisés en parfumerie, en cosmétique ou pour des traitements pharmaceutiques. En effet, ce type de flacon contient un liquide qui est restitué par un système de distribution comprenant une pompe ou une valve à actionnement manuel, ledit système étant actionné par un bouton poussoir pour permettre la pulvérisation du liquide.In a particular application, the dispensing system is intended to equip bottles used in perfumery, in cosmetics or for pharmaceutical treatments. Indeed, this type of bottle contains a liquid which is returned by a dispensing system comprising a pump or a manually operated valve, said system being actuated by a push button to allow the spraying of the liquid.

De tels boutons poussoirs sont classiquement réalisés en deux ou trois parties : un corps d'actionnement, une buse de pulvérisation du liquide et éventuellement un enjoliveur recouvrant ledit corps, lesdites parties étant assemblées entre elles pour former le bouton poussoir. En particulier, la buse de pulvérisation peut être agencée pour former un aérosol avec le liquide, notamment en étant pourvue d'une chambre de distribution dite tourbillonnaire.Such push buttons are conventionally made in two or three parts: an actuating body, a liquid spray nozzle and possibly a hubcap covering said body, said parts being assembled together to form the push button. In particular, the spray nozzle may be arranged to form an aerosol with the liquid, in particular by being provided with a so-called vortex distribution chamber.

Après assemblage des différentes parties, le bouton poussoir présente une chambre de distribution en communication avec une cheminée qui est formée dans le corps, ladite chambre étant pourvue d'au moins un orifice de distribution. Ainsi, en montant la cheminée sur le système de distribution, notamment sur le gicleur d'un tel système, il est possible de distribuer le liquide par appui manuel axial sur le bouton poussoir.After assembly of the various parts, the push button has a distribution chamber in communication with a chimney which is formed in the body, said chamber being provided with at least one dispensing orifice. Thus, by mounting the chimney on the distribution system, in particular on the nozzle of such a system, it is possible to distribute the liquid by axial manual support on the push button.

Toutefois, cet assemblage limite les possibilités de réalisation de la chambre de distribution pour l'acheminement et le traitement du flot de liquide. En particulier, il n'est pas possible de réaliser deux orifices de distribution d'axes convergents en un point situé dans un plan parfaitement déterminé et reproductible industriellement en grandes cadences.However, this assembly limits the possibilities of realization of the distribution chamber for the routing and treatment of the flow of liquid. In particular, it is not possible to make two convergent axis distribution orifices at a point situated in a perfectly determined plane and reproducible industrially in high rates.

On connaît également, notamment pour la distribution de liquides visqueux, des boutons poussoirs réalisés en une seule pièce pour intégrer la chambre de distribution. Toutefois, ces pièces étant réalisées par moulage, les agencements de chambres accessibles sont limités par les contraintes de démoulage.Also known, particularly for the distribution of viscous liquids, push buttons made in one piece to integrate the distribution chamber. However, these parts being made by molding, the Accessible room arrangements are limited by demolding stresses.

L'invention a pour but de résoudre les problèmes de l'art antérieur en proposant notamment un bouton poussoir qui est réalisé en deux parties entre lesquelles la chambre de distribution est formée, de sorte à augmenter les possibilités de réalisation de ladite chambre, notamment par moulage.The invention aims to solve the problems of the prior art by proposing in particular a push button which is made in two parts between which the distribution chamber is formed, so as to increase the possibilities of making said chamber, in particular by molding.

A cet effet, et selon un premier aspect, l'invention propose un bouton poussoir d'actionnement d'un système de distribution d'un liquide, ledit bouton poussoir comprenant un corps et une chambre de distribution en communication avec une cheminée qui est formée dans ledit corps pour amener le liquide, ladite chambre étant pourvue d'au moins un orifice de distribution du liquide amené, ledit bouton poussoir comprenant un chapeau rapporté qui est associé au corps avec la paroi supérieure dudit corps disposé en regard de la paroi inférieure du chapeau, une empreinte étant formée sur au moins l'une de ces parois de sorte à former la chambre de distribution entre lesdites parois.For this purpose, and according to a first aspect, the invention proposes a push button for actuating a liquid distribution system, said push button comprising a body and a distribution chamber in communication with a chimney which is formed. in said body for supplying the liquid, said chamber being provided with at least one dispensing orifice of the supplied liquid, said push button comprising an attached cap which is associated with the body with the upper wall of said body arranged facing the lower wall of the cap, an impression being formed on at least one of these walls so as to form the distribution chamber between said walls.

Selon un deuxième aspect, l'invention propose un système de distribution d'un liquide comprenant une pompe ou une valve à actionnement manuel sur laquelle la cheminée d'un tel bouton poussoir est montée pour permettre la distribution du liquide au travers d'au moins un orifice.According to a second aspect, the invention proposes a liquid distribution system comprising a pump or a manually operated valve on which the chimney of such a push button is mounted to allow the distribution of the liquid through at least one an orifice.

Dans la description, les termes de positionnement dans l'espace sont pris en référence aux axes des différentes pièces formant le bouton poussoir.In the description, the terms of positioning in the space are taken with reference to the axes of the various parts forming the push button.

En relation avec les figures, on décrit ci-dessous un bouton poussoir de distribution, notamment de pulvérisation, d'un système de distribution d'un liquide, ledit liquide pouvant être de toute nature, notamment utilisé en parfumerie, en cosmétique ou pour des traitements pharmaceutiques.In relation to the figures, a push button for dispensing, in particular spraying, a dispensing system for a liquid is described below, said liquid being able to be of any kind, in particular used in perfumery, in cosmetics or for pharmaceutical treatments.

Le bouton poussoir comprend un corps d'actionnement 1 présentant, d'une seule pièce, une jupe extérieure 2 et une jupe intérieure 3, lesdites jupes s'étendent sous une paroi supérieure 4 avec ladite jupe intérieure entourée par ladite jupe extérieure. La jupe intérieure 3 délimite un logement 5 de montage du bouton poussoir sur le système de distribution. Le logement 5 est en communication avec une cheminée 6 qui est formée axialement dans le corps 1 pour amener le liquide dans une chambre de distribution 7 en communication avec ladite cheminée, ladite chambre étant pourvue d'au moins un orifice de distribution 8 du liquide amené.The push button comprises an actuating body 1 having, in one piece, an outer skirt 2 and an inner skirt 3, said skirts extend under an upper wall 4 with said inner skirt surrounded by said outer skirt. The inner skirt 3 defines a housing 5 for mounting the push button on the dispensing system. The housing 5 is in communication with a chimney 6 which is formed axially in the body 1 to bring the liquid into a distribution chamber 7 in communication with said chimney, said chamber being provided with at least one dispensing orifice 8 of the supplied liquid. .

Sur la figure 2, le système de distribution présente un gicleur G qui est inséré de façon étanche dans le logement 5. De façon connue, le système de distribution comprend par ailleurs des moyens de montage sur le col C d'un flacon contenant le liquide et des moyens de prélèvement T du liquide à l'intérieur dudit flacon qui sont agencés pour alimenter le gicleur G en liquide sous pression.On the figure 2 , the dispensing system has a nozzle G which is sealingly inserted into the housing 5. In known manner, the dispensing system further comprises means for mounting on the neck C of a bottle containing the liquid and means for sampling T of the liquid inside said bottle which are arranged to supply the nozzle G with liquid under pressure.

Pour ce faire, le système de distribution comprend une pompe P à actionnement manuel ou, dans le cas où le liquide est conditionné sous pression dans le flacon, une valve à actionnement manuel. Ainsi, lors d'un déplacement manuel du bouton poussoir, la pompe P ou la valve est actionnée pour alimenter le gicleur G en liquide sous pression.To do this, the dispensing system comprises a manually operated pump P or, in the case where the liquid is packaged under pressure in the bottle, a manually operated valve. Thus, during a manual movement of the push button, the pump P or the valve is actuated to supply the nozzle G in liquid under pressure.

Le bouton poussoir comprend également un chapeau 9 rapporté qui présente sensiblement la même enveloppe cylindrique de révolution que le corps 1, ledit chapeau étant associé sur le corps 1 de sorte à former une pièce unitaire d'actionnement du système de distribution. En outre, le bouton poussoir peut comprendre un enjoliveur d'aspect, par exemple en aluminium anodisé ou teinté, qui est monté sur le chapeau 9 et/ou sur le corps 1, en recouvrant la paroi supérieure 10 du chapeau 9 et/ou la face extérieure de la jupe extérieure 2 tout en laissant libre l'orifice de distribution 8.The push button also comprises an attached cap 9 which has substantially the same cylindrical envelope of revolution as the body 1, said cap being associated on the body 1 so as to form a unitary actuating part of the dispensing system. In addition, the push button may comprise an aspect trim, for example anodized aluminum or tinted, which is mounted on the cap 9 and / or on the body 1, covering the upper wall 10 of the cap 9 and / or the outer face of the outer skirt 2 while leaving free the dispensing orifice 8.

Le corps 1 et le chapeau 9 peuvent être réalisés par moulage d'une matière plastique, notamment dans la même matière ou dans deux matières proches, et être assemblés par soudage ou par collage. La soudure peut être de type ultrasonique ou haute fréquence. Les matières peuvent être de type polyoléfinique, par exemple en polypropylène ou en polyéthylène.The body 1 and the cap 9 may be made by molding a plastic material, in particular in the same material or in two similar materials, and be assembled by welding or gluing. The weld can be ultrasonic or high frequency type. The materials may be of polyolefinic type, for example polypropylene or polyethylene.

Le chapeau 9 comprend une paroi supérieure 10 permettant à l'utilisateur d'exercer sur elle un appui digital afin de pouvoir déplacer axialement et de façon conjointe le corps 1, et donc permettre l'actionnement du système de distribution par appui axial sur le bouton poussoir. Le chapeau 9 présente également une paroi inférieure 11 qui est disposé en regard de la paroi supérieure 4 du corps 1 pour permettre l'association dudit chapeau sur ledit corps.The cap 9 comprises an upper wall 10 allowing the user to exert on it a digital support in order to be able to axially and jointly move the body 1, and thus allow the actuation of the dispensing system by pressing the button axially. button. The cap 9 also has a bottom wall 11 which is arranged facing the upper wall 4 of the body 1 to allow the association of said cap on said body.

La chambre de distribution 7 est formée entre les parois supérieure 4 et inférieure 11 par formation d'une empreinte 12 sur au moins l'une de ces parois 4, 11, l'orifice de distribution 8 étant disposé sur la périphérie du bouton poussoir pour une distribution latérale du liquide.The distribution chamber 7 is formed between the upper 4 and lower 11 walls by forming a cavity 12 on at least one of these walls 4, 11, the dispensing orifice 8 being disposed on the periphery of the push button for a lateral distribution of the liquid.

Dans les modes de réalisation représentés, l'empreinte 12 est formée en creux dans la paroi inférieure 11 du chapeau 9, la partie de la paroi supérieure 4 qui est disposée en regard de l'empreinte 12 étant plane. Ainsi, la chambre de distribution 7 est délimitée en partie supérieure par la partie de la paroi inférieure 11 sur laquelle est formée le fond de l'empreinte 12, et en partie inférieure par la paroi plane 4 dans laquelle la cheminée 6 débouche. Toutefois on peut prévoir une empreinte 12 sur la paroi supérieure 4 du corps 1 ou une coopération d'empreintes formées respectivement sur l'une de ces parois 4, 11.In the embodiments shown, the cavity 12 is hollowed out in the bottom wall 11 of the cap 9, the part of the upper wall 4 which is disposed facing the footprint 12 being flat. Thus, the distribution chamber 7 is delimited in the upper part by the portion of the bottom wall 11 on which is formed the bottom of the cavity 12, and in the lower part by the flat wall 4 in which the chimney 6 opens. However one can provide an impression 12 on the upper wall 4 of the body 1 or a fingerprint interaction formed respectively on one of these walls 4, 11.

Cette réalisation de la chambre de distribution 7 en deux parties au moyen d'un chapeau 9 et d'un corps 1 qui sont associés après fabrication et orientation relative selon leur axe commun, permet de limiter les contraintes de démoulage de sorte à augmenter les possibilités de réalisation de ladite chambre.This embodiment of the distribution chamber 7 in two parts by means of a cap 9 and a body 1 which are associated after manufacture and relative orientation along their common axis, limits the demolding stresses so as to increase the possibilities of realization of said chamber.

En particulier, comme représenté sur les figures 1 à 3, il est possible de réaliser deux orifices de distribution 8 selon respectivement un axe, l'orientation relative des axes de distribution étant convergente pour former une zone d'intersection des portions de liquide qui sont distribuées au travers de respectivement un orifice 8. Cette réalisation permet de générer des flots de liquide qui s'éclatent en micro gouttelettes lors de leur collision dans la zone d'intersection.In particular, as shown in Figures 1 to 3 it is possible to make two dispensing orifices 8 respectively along an axis, the relative orientation of the distribution axes being convergent to form an intersection zone of the liquid portions which are distributed through respectively an orifice 8. This embodiment allows the generation of liquid streams that burst into micro droplets during their collision in the intersection zone.

Sur ces figures, les orifices de distribution 8 sont formés sur le bord extérieur 12a de l'empreinte 12 qui est disposé en aval de la chambre de distribution 7. Plus précisément, chaque orifice 8 est formé par une encoche dans la paroi extérieure 12a, lesdits orifices étant délimités en partie supérieure par le fond de l'empreinte 12 et en partie inférieure par la paroi plane 4. En outre, le bord extérieur 12a présente un profil concave et les orifices de distribution 8 sont disposés symétriquement le long dudit profil de sorte à orienter leur axe de distribution.In these figures, the dispensing orifices 8 are formed on the outer edge 12a of the cavity 12 which is disposed downstream of the distribution chamber 7. More specifically, each orifice 8 is formed by a notch in the outer wall 12a, said orifices being delimited in the upper part by the bottom of the cavity 12 and in the lower part by the flat wall 4. In addition, the outer edge 12a has a concave profile and the distribution orifices 8 are arranged symmetrically along the said profile. to orient their distribution axis.

Par ailleurs, le bord extérieur 12a est disposé en creux sur la périphérie du bouton poussoir de sorte à former un logement 13 au fond duquel l'orifice de distribution 8 est formé. Plus précisément, le logement 13 est formé sur le bord du chapeau 9 dans la continuité de la paroi inférieure 11.Furthermore, the outer edge 12a is recessed on the periphery of the push button so as to form a housing 13 at the bottom of which the dispensing orifice 8 is formed. More specifically, the housing 13 is formed on the edge of the cap 9 in the continuity of the bottom wall 11.

En outre, le logement 13 est prolongé sur la paroi supérieure 4 par formation d'un creux complémentaire 14 sur le bord du corps 1, le fond dudit creux étant disposé dans le prolongement du bord extérieur 12a. Sur les figures 1 à 3, le logement 13 présente une géométrie sphérique. En fonction de l'orientation relative des axes de distribution des orifices 8, on peut prévoir que la zone d'intersection soit disposée à l'intérieur ou à l'extérieur du logement 13.In addition, the housing 13 is extended on the upper wall 4 by forming a complementary recess 14 on the edge of the body 1, the bottom of said hollow being disposed in the extension of the outer edge 12a. On the Figures 1 to 3 , the housing 13 has a spherical geometry. Depending on the relative orientation of the distribution axes of the orifices 8, it is possible for the intersection zone to be disposed inside or outside the housing 13.

Sur les figures 3, le bord de l'empreinte 12 est pourvu d'un bourrelet d'étanchéité 15 saillant vers la paroi supérieure 4, ledit bourrelet étant en appui étanche sur la paroi supérieure plane 4, de sorte à améliorer l'étanchéité de la chambre de distribution 7.On the figures 3 , the edge of the cavity 12 is provided with a sealing bead 15 projecting towards the upper wall 4, said bead being in sealing abutment on the flat upper wall 4, so as to improve the sealing of the distribution chamber 7.

En outre, les parois 4, 11 peuvent être pourvues de moyens de positionnement angulaire et/ou d'association du chapeau 9 sur le corps 1. Sur les figures 3 et 4, ces moyens comprennent trois plots 16 formés sur la paroi supérieure 4 et trois évidements 17 formés sur la paroi inférieure 11. Chaque plot 16 est reçu dans un évidement 17 dans une position angulaire définie entre le chapeau 9 et le corps 1, l'association pouvant être réalisée par serrage ou par encliquetage des plots 16 dans les évidements 17.In addition, the walls 4, 11 may be provided with means for angular positioning and / or association of the cap 9 on the body 1. Figures 3 and 4 these means comprise three studs 16 formed on the upper wall 4 and three recesses 17 formed on the bottom wall 11. Each stud 16 is received in a recess 17 in an angular position defined between the cap 9 and the body 1, the association being able to be achieved by clamping or snapping the studs 16 into the recesses 17.

Ces réalisations sans soudage ni collage du chapeau 9 sur le corps 1 permettent d'assembler des pièces en matières différentes, par exemple en matière tendre comme le polypropylène pour le corps 1 et en matière rigide comme le polyoxyméthylène (POM), les copolymères cyclo-oléfiniques (COC) ou le poly butylène téréphtalate (PBT) pour le chapeau 9, afin d'assurer un bon encliquetage ainsi qu'une bonne précision géométrique dans la réalisation de l'empreinte 12 et notamment des orifices 8. En outre, les matières peuvent être de couleur, d'aspect ou de toucher différent pour des effets esthétiques ou une meilleure ergonomie.These embodiments without welding or gluing of the cap 9 on the body 1 make it possible to assemble parts made of different materials, for example of soft material such as polypropylene for the body 1 and of rigid material such as polyoxymethylene (POM), the cyclopolycopolymers. olefinic (COC) or polybutylene terephthalate (PBT) for the cap 9, to ensure a good snap and good geometric accuracy in the realization of the footprint 12 and in particular the orifices 8. In addition, the materials may be of different colors, appearance or feel for aesthetic effects or better ergonomics.

Avantageusement, les plots 16 peuvent être réalisés dans la matière la plus rigide et les évidements 17 dans la matière la plus tendre afin d'éviter le rabotage des plots et de favoriser leur imbrication par fluage dans les évidements 17.Advantageously, the pads 16 may be made of the most rigid material and the recesses 17 in the softest material to avoid the planing the blocks and to promote their nesting by creep in the recesses 17.

Sur les figures 4, l'empreinte 12 présente une surface courbe 18 qui est formée en creux dans la paroi inférieure 11, ladite surface étant orientée vers la cheminée 6 de sorte à former déflecteur du liquide entre ladite cheminée et l'orifice de distribution 8. Ainsi, le déflecteur permet d'éclater en micro gouttelettes le jet de liquide sortant à grande vitesse de la cheminée 6, lesdites micro gouttelettes étant guidées vers l'orifice 8 le long de la surface courbe 18.On the figures 4 , the cavity 12 has a curved surface 18 which is recessed in the bottom wall 11, said surface being directed towards the chimney 6 so as to form a baffle of the liquid between said chimney and the dispensing orifice 8. deflector makes it possible to burst in micro droplets the stream of liquid leaving the chimney 6 at high speed, said micro droplets being guided towards the orifice 8 along the curved surface 18.

Plus précisément, sur les figures 4, l'empreinte 12 présente deux bords latéraux 19, 20 s'étendant axialement de part et d'autre de la cheminée 6, la surface courbe 18 étant formée entre lesdits bords. En outre, la surface courbe 18 s'étend depuis l'interface entre les parois 4, 11 vers la périphérie du bouton poussoir, l'orifice 8 étant délimité latéralement par lesdits bords latéraux.More specifically, on figures 4 , the cavity 12 has two lateral edges 19, 20 extending axially on either side of the chimney 6, the curved surface 18 being formed between said edges. In addition, the curved surface 18 extends from the interface between the walls 4, 11 towards the periphery of the push button, the orifice 8 being delimited laterally by said lateral edges.
