Description

La présente invention est relative à un dispositif d'actionnement d'un mécanisme de distribution, tel qu'une pompe ou une valve, équipant un récipient contenant un produit à distribuer, le mécanisme de distribution comprenant une tige tubulaire de commande par poussée, mobile axialement, et munie d'un orifice de distribution.The present invention relates to a device for actuating a dispensing mechanism, such as a pump or a valve, fitted to a container containing a product to be dispensed, the dispensing mechanism comprising a tubular rod for thrust control, mobile. axially, and provided with a dispensing orifice.

Plus précisément, l'invention est relative à un dispositif d'actionnement comportant un bouton-poussoir monté à l'extrémité de la tige de commande du mécanisme de distribution et muni d'une buse de sortie ménagée sensiblement au centre de sa face externe, alignée et en communication avec ladite tige, et une pièce de manoeuvre, sensiblement cylindrique, comportant une surface supérieure annulaire constituant une zone d'application de force, et des moyens d'appui aptes à coopérer avec des moyens de butée de manière telle que l'application d'une force d'actionnement en un point quelconque de ladite surface supérieure annulaire de la pièce de manoeuvre provoque un déplacement du bouton-poussoir et de la tige de commande pour actionner le mécanisme de distribution.More specifically, the invention relates to an actuating device comprising a push button mounted at the end of the control rod of the dispensing mechanism and provided with an outlet nozzle formed substantially in the center of its external face, aligned and in communication with said rod, and an operating part, substantially cylindrical, comprising an annular upper surface constituting a force application zone, and support means capable of cooperating with abutment means such that the application of an actuating force at any point of said annular upper surface of the operating part causes a displacement of the push button and of the control rod to actuate the dispensing mechanism.

Un dispositif d'actionnement de ce type pour une valve de distribution, notamment d'un aérosol pressurisé, est décrit dans le document FR-A-2 661 661 de la Société déposante (mode de réalisation des figures 5 et 6 de ce document antérieur).An actuating device of this type for a dispensing valve, in particular of a pressurized aerosol, is described in document FR-A-2 661 661 of the applicant company (embodiment of FIGS. 5 and 6 of this prior document ).

Dans cette réalisation antérieure, le bouton-poussoir est un téton réalisé d'un seul tenant avec la pièce de manoeuvre.In this previous embodiment, the push button is a stud made in one piece with the operating part.

Sous l'effet de l'application d'une force sur la surface supérieure annulaire de la pièce de manoeuvre, et du fait du contact entre les moyens d'appui de la pièce de manoeuvre et les moyens de butée, la pièce de manoeuvre agit comme un levier pour repousser le bouton-poussoir et donc la tige de commande du mécanisme de distribution sur laquelle il est monté.Under the effect of the application of a force on the upper annular surface of the operating part, and due to the contact between the support means of the operating part and the stop means, the operating part acts like a lever to push back the push button and therefore the control rod of the dispensing mechanism on which it is mounted.

Du fait que le bouton-poussoir est d'un seul tenant avec la pièce de manoeuvre, le mouvement de pivotement de cette dernière, provoqué lors de l'actionnement, entraîne également un mouvement de pivotement du bouton-poussoir qui se trouve repoussé en étant incliné par rapport à l'axe de la tige de commande du mécanisme de distribution.Because the push button is in one piece with the operating part, the pivoting movement of the latter, caused during actuation, also causes a pivoting movement of the push button which is pushed back by being inclined with respect to the axis of the control rod of the dispensing mechanism.

Des efforts non axiaux sont donc appliqués à la tige de commande du mécanisme d'actionnement, ces efforts pouvant, à la suite d'actionnements répétés, entraîner la cassure de la tige.Non-axial forces are therefore applied to the control rod of the actuation mechanism, these forces being able, following repeated actuations, to cause the rod to break.

De plus, du fait de l'inclinaison du bouton poussoir, la buse de celui-ci ne se trouve plus en alignement axial avec la tige du mécanisme de distribution, de telle sorte que le produit sortant de la buse n'est pas projeté selon l'axe du récipient.In addition, due to the inclination of the push button, the nozzle thereof is no longer in axial alignment with the rod of the dispensing mechanism, so that the product leaving the nozzle is not projected according to the axis of the container.

En outre, du fait qu'une partie notable de la force appliquée à la pièce de manoeuvre ne contribue pas à l'effort de poussée axiale sur la tige du mécanisme de distribution, la course axiale de celle-ci est relativement faible, et notamment insuffisante pour commander le mécanisme de distribution lorsque celui-ci est sous la forme d'une pompe.In addition, because a significant part of the force applied to the operating part does not contribute to the axial thrust force on the rod of the dispensing mechanism, the axial stroke thereof is relatively small, and in particular insufficient to control the dispensing mechanism when it is in the form of a pump.

La présente invention se propose de réaliser un dispositif d'actionnement qui, tout en présentant les avantages du dispositif connu par FR-A-2 661 661, en particulier la possibilité d'actionnement avec une faible force appliquée par un doigt quelconque de l'utilisateur en un point quelconque d'une zone d'application de force s'étendant sur 360°, évite les inconvénients mentionnés ci-dessus.The present invention proposes to produce an actuation device which, while having the advantages of the device known from FR-A-2 661 661, in particular the possibility of actuation with a low force applied by any finger of the user at any point of a force application area extending over 360 °, avoids the drawbacks mentioned above.

Le dispositif d'actionnement selon la présente invention se caractérisé essentiellement par le fait que la pièce de manoeuvre est reliée au bouton-poussoir par une articulation à rotule.The actuating device according to the present invention is essentially characterized by the fact that the operating part is connected to the push button by a ball joint.

Dans un mode de réalisation préféré, le bouton-poussoir présente une partie supérieure hémisphérique au sommet de laquelle est ménagée la buse de sortie, la pièce de manoeuvre comportant une chambre centrale ouverte définie par une paroi de profil sphérique dans laquelle est engagée en correspondance de forme et avec possibilité de rotation relative, la partie hémisphérique du bouton poussoir.In a preferred embodiment, the push button has a hemispherical upper part at the top of which is formed the outlet nozzle, the operating part comprising an open central chamber defined by a wall of spherical profile in which is engaged in correspondence of shape and with possibility of relative rotation, the hemispherical part of the push button.

De préférence, la pièce de manoeuvre comporte une douille cylindrique intérieure dans laquelle est réalisée ladite chambre et une douille cylindrique extérieure, lesdites douilles étant coaxiales et reliées rigidement l'une à l'autre, de préférence par un voile continu de profil tronconique.Preferably, the operating part comprises an inner cylindrical sleeve in which said chamber is made and an outer cylindrical sleeve, said sockets being coaxial and rigidly connected to each other, preferably by a continuous web of frustoconical profile.

Avantageusement, la surface supérieure annulaire formant zone d'application de force est réalisée sous forme de collerette périphérique extérieure à l'extrémité supérieure de la douille extérieure.Advantageously, the annular upper surface forming a force application zone is produced in the form of an external peripheral flange at the upper end of the external sleeve.

La douille extérieure comporte avantageusement à son extrémité inférieure une seconde collerette périphérique extérieure venant en appui contre une collerette périphérique intérieure à l'extrémité supérieure d'une frette cylindrique montée à l'extrémité supérieure du récipient et logeant le mécanisme de distribution.The outer sleeve advantageously comprises at its lower end a second outer peripheral flange bearing against an inner peripheral flange at the upper end of a cylindrical hoop mounted at the upper end of the container and housing the dispensing mechanism.

Dans la mesure où, selon l'invention, le bouton-poussoir constitue une pièce séparée de la pièce de manoeuvre et ne subit pas de mouvement de pivotement lors de l'actionnement de celle-ci, il peut être avantageusement solidarisé de l'extrémité de la tige de commande du mécanisme de distribution, notamment par emmanchement à force. Ceci assure une excellente étanchéité vis-à-vis du produit entre la tige et la buse de sortie du bouton-poussoir.Insofar as, according to the invention, the push-button constitutes a part separate from the operating part and does not undergo a pivoting movement when the latter is actuated, it can advantageously be secured to the end of the control rod of the dispensing mechanism, in particular by force fitting. This ensures an excellent seal against the product between the rod and the push button outlet nozzle.

Dans le but de mieux faire comprendre l'invention, on va maintenant en décrire, à titre d'exemple nullement limitatif, un mode préféré de réalisation en se référant aux figures 1 à 3 du dessin annexé.In order to better understand the invention, we will now describe, by way of nonlimiting example, a preferred embodiment with reference to Figures 1 to 3 of the accompanying drawing.

Dans ce dessin :

  • la figure 2 est une vue analogue à la figure 1 du dispositif en position d'actionnement,
  • la figure 3 est une vue de dessus du dispositif dans la position de la figure 1 et,
  • les figures 4 et 5 sont des vues analogues aux figures 1 et respectivement 2 d'un dispositif correspondant à l'art antérieur.
In this drawing:
  • Figure 1 is a schematic view partially in section of a device according to the invention in the rest position.
  • FIG. 2 is a view similar to FIG. 1 of the device in the actuation position,
  • FIG. 3 is a top view of the device in the position of FIG. 1 and,
  • Figures 4 and 5 are views similar to Figures 1 and 2 respectively of a device corresponding to the prior art.

On se réfère tout d'abord aux figures 1 à 3.We first refer to Figures 1 to 3.

On y a illustré de manière fragmentaire un récipient 1 contenant un produit à distribuer et muni à sa partie supérieure d'un mécanisme de distribution 2, qui peut être une valve notamment lorsque le produit à distribuer est un aérosol pressurisé, ou peut être une pompe pour distribuer un produit notamment sous forme de spray ou de mousse.There is illustrated in a fragmentary manner a container 1 containing a product to be dispensed and provided at its upper part with a dispensing mechanism 2, which can be a valve in particular when the product to be dispensed is a pressurized aerosol, or can be a pump. to distribute a product, in particular in the form of a spray or foam.

Le mécanisme de distribution 2 est muni d'une tige tubulaire de commande par poussée, mobile axialement, 3, ladite tige étant munie à son extrémité d'un orifice de distribution.The dispensing mechanism 2 is provided with a tubular rod for thrust control, axially movable, 3, said rod being provided at its end with a dispensing orifice.

A l'extrémité supérieure du récipient est fixée, par exemple par encliquetage, une frette cylindrique 4 munie à son extrémité supérieure d'une collerette périphérique intérieure 5.At the upper end of the container is fixed, for example by snap-fastening, a cylindrical hoop 4 provided at its upper end with an inner peripheral flange 5.

A l'extrémité supérieure de la tige 3 est mis en place un bouton-poussoir 6 comportant une partie supérieure hémisphérique 7 et une partie inférieure cylindrique 8.At the upper end of the rod 3 is placed a push button 6 comprising a hemispherical upper part 7 and a cylindrical lower part 8.

Au sommet de la partie supérieure hémisphérique 7 du bouton-poussoir est ménagée une buse de distribution 9 en communication avec l'extrémité supérieure de la tige 3.At the top of the hemispherical upper part 7 of the push button is provided a dispensing nozzle 9 in communication with the upper end of the rod 3.

Le bouton-poussoir 6 est évidé intérieurement pour pouvoir être engagé sur l'extrémité de la tige 3.The push button 6 is hollowed out internally so that it can be engaged on the end of the rod 3.

Avantageusement, l'évidement intérieur du bouton-poussoir 6 est réalisé de manière à permettre un emmanchement à force de la tige par rapport au bouton-poussoir ce qui permet de solidariser ces éléments et assurer une excellente étanchéité vis-à-vis du produit distribué.Advantageously, the interior recess of the push button 6 is made so as to allow a force fitting of the rod relative to the push button which allows these elements to be secured and ensure an excellent seal with respect to the product distributed. .

Le dispositif selon l'invention comporte une pièce de manoeuvre, désignée globalement par 10, réalisée de préférence d'un seul tenant par moulage de matière plastique et comprenant une douille extérieure 11 et une douille intérieure 12, coaxiales, la douille intérieure 12 présentant une hauteur plus faible que la douille extérieure 11 et étant reliée à elle par un voile continu de profil tronconique 13.The device according to the invention comprises an operating part, generally designated by 10, preferably produced in a single piece by molding of plastic material and comprising an outer sleeve 11 and an inner sleeve 12, coaxial, the inner sleeve 12 having a lower height than the outer sleeve 11 and being connected to it by a continuous veil of frustoconical profile 13.

En variante, le voile pourrait être constitué de membrures séparées agencées pour réaliser une liaison rigide entre la douille intérieure 12 et la douille extérieure 11.As a variant, the web could be made up of separate members arranged to make a rigid connection between the inner bush 12 and the outer bush 11.

A l'intérieur de la douille 12 est ménagée une chambre pour la réception à rotation de la partie supérieure hémisphérique 7 du bouton-poussoir 6.Inside the sleeve 12 is provided a chamber for receiving the hemispherical upper part 7 of the push-button 6 in rotation.

Cette chambre ouverte est définie par une paroi de profil sphérique 14 de la douille 12.This open chamber is defined by a wall of spherical profile 14 of the socket 12.

Le diamètre de la partie hémisphérique du bouton-poussoir 6 et celui de la pièce de manoeuvre au niveau de la douille centrale 12 et du voile 13 sont déterminés de telle sorte que pour toute position de la pièce de manoeuvre, l'orifice de sortie de la buse 9 se trouve dégagé.The diameter of the hemispherical part of the push button 6 and that of the operating part at the level of the central sleeve 12 and of the web 13 are determined so that for any position of the operating part, the outlet orifice of the nozzle 9 is clear.

La douille extérieure 11 de la pièce de manoeuvre 10 comporte une collerette périphérique extérieure 15 à son extrémité supérieure et une autre collerette périphérique extérieure 16 à son extrémité inférieure.The outer sleeve 11 of the operating part 10 has an outer peripheral flange 15 at its upper end and another outer peripheral flange 16 at its lower end.

La collerette supérieure 15 constitue une zone annulaire d'application de force pour l'actionnement du dispositif, et la collerette 16 constitue en coopération avec la collerette 5 de la frette 4 des moyens d'appui et de butée aptes à former un point d'appui de levier diamétralement opposé à l'emplacement sur lequel est appliquée une force d'appui sur la face supérieure de la collerette 15, comme cela ressort de la figure 2.The upper flange 15 constitutes an annular force application zone for actuating the device, and the flange 16 constitutes, in cooperation with the flange 5 of the hoop 4, support and abutment means capable of forming a point of lever support diametrically opposite to the location on which a pressing force is applied to the upper face of the flange 15, as can be seen in FIG. 2.

Sous l'effet de l'appui exercé, la pièce de manoeuvre pivote et, du fait de sa liaison d'articulation à rotule au niveau de la douille 12 avec le bouton-poussoir 6, transmet au bouton-poussoir un mouvement de déplacement axial d'amplitude importante qui déplace de manière correspondante la tige 3 du mécanisme de distribution 2.Under the effect of the support exerted, the maneuvering piece pivots and, due to its ball joint connection at the level of the socket 12 with the push button 6, transmits to the push button a movement of axial displacement of large amplitude which correspondingly displaces the rod 3 of the dispensing mechanism 2.

On voit sur la figure 2 que le jet projeté ainsi au travers de la buse 9 comporte un axe aligné avec l'axe de la tige et du récipient.We see in Figure 2 that the jet thus projected through the nozzle 9 has an axis aligned with the axis of the rod and the container.

On a, à titre d'exemple comparatif, illustré aux figures 4 et 5 un dispositif réalisé en mettant en oeuvre des enseignements connus de l'état de la technique avec en particulier un bouton-poussoir 6' solidarisé ou réalisé d'un seul tenant avec une pièce de manoeuvre 10'.As a comparative example, there is illustrated in FIGS. 4 and 5 a device produced by implementing teachings known from the state of the art with in particular a push button 6 ′ secured or produced in one piece. with a 10 'operating part.

Comme on le voit clairement sur la figure 5, dans la position d'actionnement, le bouton-poussoir 6' s'incline par rapport à la tige 3', le jet projeté n'est plus orienté dans l'axe de la tige et la course de déplacement de la tige 3' est plus faible.As can be clearly seen in FIG. 5, in the actuating position, the push button 6 ′ tilts relative to the rod 3 ′, the projected jet is no longer oriented in the axis of the rod and the displacement stroke of the rod 3 'is shorter.

La mise en place du dispositif selon l'invention tel qu'illustré aux figures 1 à 3 s'effectue de la manière suivante.The installation of the device according to the invention as illustrated in Figures 1 to 3 is carried out as follows.

On met en place le bouton-poussoir 6 à l'extrémité de la tige 3 du mécanisme de distribution monté sur le récipient 1.The push button 6 is put in place at the end of the rod 3 of the dispensing mechanism mounted on the container 1.

On engage dans la frette cylindrique 4, avant montage de celle-ci sur le récipient, la pièce de manoeuvre 10.The operating piece 10 is engaged in the cylindrical hoop 4, before mounting of the latter on the container.

A cet effet, il importe que le diamètre extérieur de la collerette supérieure 15 de la pièce de manoeuvre soit quelque peu inférieur au diamètre intérieur de la collerette 5 de la frette 4.For this purpose, it is important that the outside diameter of the upper flange 15 of the operating part is somewhat less than the inside diameter of the flange 5 of the hoop 4.

On engage alors la douille intérieure 12 de la pièce de manoeuvre 10 sur le bouton-poussoir 6 et l'on fixe la frette 4 sur le récipient.The inner sleeve 12 of the operating part 10 is then engaged on the push-button 6 and the hoop 4 is fixed on the container.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter différentes variantes et modifications sans pour autant sortir ni de son cadre ni de son esprit.Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be made different variants and modifications without departing from its scope or of his mind.
