Description

La présente invention concerne un distributeur de produits visqueux, tel que du savon liquide ou pâteux, comprenant essentiellement une partie inférieure abritant un dispositif de distribution de doses du produit visqueux, à travers une bouche de sortie ayant la forme d'une projection tubulaire actionné par un organe de commande et d'une coquille surmontant ladite partie inférieure agencée pour abriter le produit à distribuer en vrac ou dans un conditionnement adéquat, la bouche de sortie étant coiffée par un manchon perforé d'un matériau déformable élastiquement,The present invention relates to a dispenser of viscous products, such as liquid or pasty soap, essentially comprising a lower part housing a device for dispensing doses of the viscous product, through an outlet mouth having the form of a tubular projection actuated by a control member and a shell surmounting said lower part arranged to house the product to be dispensed in bulk or in an adequate packaging, the outlet mouth being capped by a sleeve perforated with an elastically deformable material,

De tels distributeurs sont essentiellement utilisés dans les lieux publics où les êtres humains ont besoin de se laver les mains, tels que toilettes, cabinets médicaux, usines, ...Such dispensers are mainly used in public places where human beings need to wash their hands, such as toilets, medical offices, factories, ...

Ces dispositifs sont en principe fixés contre une paroi à côté d'un lavabo et sont munis à leur partie inférieure d'un levier qu'il suffit de tirer une ou deux fois pour obtenir une ou deux doses d'un savon liquide qui tombe dans la paume de la main qui a actionné le levier. En fonction de la viscosité du produit utilisé, ce distributeur présente quelques désavantages :These devices are in principle fixed against a wall next to a sink and are provided at their lower part with a lever which is sufficient to pull once or twice to obtain one or two doses of a liquid soap which falls into the palm of the hand that actuated the lever. Depending on the viscosity of the product used, this dispenser has some disadvantages:

après l'expulsion de la dose du produit, il reste toujours à proximité de la bouche de sortie une goutte du produit laquelle soit elle tombe au bout de quelque temps par gravité ce que, d'une part, provoque un gaspillage inutile du produit, et d'autre part, la goutte du produit tombe sur le sol ou des surfaces laissant des taches qui ne sont pas esthétiques soit si le distributeur n'est pas utilisé pendant un intervalle de temps relativement long et en fonction de la viscosité du produit, la goutte du produit peut se solidifier dans la bouche de sortie qui en principe est ouverte à l'air ambient et provoquer ainsi l'obturation de ladite bouche.after the expulsion of the dose of the product, there always remains close to the outlet mouth a drop of the product which either it falls after some time by gravity which, on the one hand, causes an unnecessary waste of the product, and on the other hand, the drop of the product falls on the ground or surfaces leaving stains which are not aesthetic either if the dispenser is not used during an interval of relatively long time and depending on the viscosity of the product, the drop of the product can solidify in the outlet mouth which in principle is open to ambient air and thus cause the closure of said mouth.

La présente invention a pour but de pallier les inconvénients susmentionnés en proposant un distributeur empêchant, d'une part, la goutte restante dans la bouche de sortie du distributeur de tomber et, d'autre part, d'éviter l'éventuel obturation de ladite bouche si le distributeur n'est pas utilisé pendant un intervalle temporel relativement long.The object of the present invention is to overcome the aforementioned drawbacks by proposing a dispenser preventing, on the one hand, the drop remaining in the outlet mouth of the dispenser from falling and, on the other hand, avoiding the possible closure of said mouth if the dispenser is not used for a relatively long time interval.

Le distributeur selon l'invention est caractérisé par le fait que le manchon est muni à l'extrémité de sortie en forme de dôme d'une fente fermée en position de repos du distributeur et s'ouvrant sous la pression conduisant à l'expulsion d'une dose du produit à distribuer, que la partie inférieure dudit distributeur et notamment le dispositif de distribution et la bouche de sortie coiffée de l'élément déformable élastiquement sont agencés de sorte que lorsque l'organe de commande arrive en fin de course, dans la phase d'expulsion du produit, un petit volume intérieur dudit élément déformable élastiquement est supprimé, ledit volume étant recréé lorsque l'organe de contrôle revient vers sa position initiale provoquant ainsi une dépression à l'intérieur dudit capuchon déformable élastiquement.The dispenser according to the invention is characterized in that the sleeve is provided at the dome-shaped outlet end with a slot closed in the dispenser's rest position and opening under pressure leading to expulsion d a dose of the product to be dispensed, that the lower part of said dispenser and in particular the dispensing device and the outlet mouth capped with the elastically deformable element are arranged so that when the control member reaches the end of its travel, in the expulsion phase of the product, a small internal volume of said elastically deformable element is eliminated, said volume being recreated when the control member returns to its initial position thus causing a vacuum inside said elastically deformable cap.

L'avantage de ce dispositif est que la bouche de sortie est en position de repos fermée pratiquement hermétiquement, puisque le manchon en matériau déformable élastiquement grâce à sa forme et à l'unique fente peut être considéré en position de repos comme fermé hermétiquement, ce qui empêche le produit de se dessécher et d'obturer la bouche. D'autre part, la quantité du produit se trouvant à l'intérieur de la bouche ne peut tomber par gravité puisque le manchon reste fermé tant qu'une pression n'est pas exercée sur le produit pour provoquer l'ouverture de la fente se trouvant sur l'extrémité en forme de dôme du manchon. En plus, la dépression créée lors de la phase retour permet d'assurer une bonne fermeture de la fente, et voire aspirer, notamment avec des produits particulièrement visqueux, une petite partie du produit qui reste accrochée aux lèvres de la fente à l'extérieur du manchon et peut provoquer les mêmes inconvénients cités précédemment.The advantage of this device is that the outlet mouth is in the rest position closed practically hermetically, since the sleeve made of elastically deformable material thanks to its shape and the single slot can be considered in the rest position as tightly closed, which prevents the product from drying out and blocking the mouth. In addition, the quantity of the product being inside the mouth cannot fall by gravity since the sleeve remains closed until a pressure is not exerted on the product to cause the opening of the slit. found on the dome end of the sleeve. In addition, the vacuum created during the return phase makes it possible to ensure good closure of the slit, and even to suck up, in particular with particularly viscous products, a small part of the product which remains attached to the lips of the slit on the outside. of the sleeve and can cause the same drawbacks mentioned above.

Donc, selon l'invention on provoque à la fin de la phase de l'expulsion du produit une diminution du volume intérieur dudit manchon et de restituer ce volume lorsque la phase d'expulsion est terminée ce qui provoque une dépression à l'intérieur du manchon qui a pour effet d'aspirer à l'intérieur du manchon la petite quantité de produit se trouvant sur les lèvres de la fente.Therefore, according to the invention, at the end of the expulsion phase of the product, a reduction in the internal volume of said sleeve is caused and this volume is restored when the expulsion phase is finished, which causes a depression inside the sleeve which has the effect of sucking inside the sleeve the small amount of product on the lips of the slot.

Pour obtenir ce résultat, selon une exécution préférée, la bouche de sortie et partant le manchon sont solidaires d'une pièce animée d'un mouvement linéaire alterné se déplaçant dans un sens dans la phase d'expulsion du produit et dans le sens contraire pour revenir à la position de repos; en outre, la projection tubulaire de la bouche de sortie est munie d'une fraisure couverte par le manchon et lorsque la bouche de sortie arrive en fin de course dans la phase d'expulsion elle vient en contact avec une saillie qui rentre dans ladite fraisure en s'appuyant sur le manchon et profitant de ses propriétés de déformation élastique pour supprimer un petit volume à l'intérieur du manchon et le restituer lorsque la bouche de sortie entame le déplacement de retour vers la position de repos provoquant ainsi une dépression permettant d'aspirer le produit se trouvant à l'extérieur du capuchon sur les lèvres de la fente.To obtain this result, according to a preferred embodiment, the outlet mouth and leaving the sleeve are integral with a part driven by an alternating linear movement moving in one direction in the phase of expulsion of the product and in the opposite direction for return to the rest position; in addition, the tubular projection of the outlet mouth is provided with a countersink covered by the sleeve and when the outlet mouth reaches the end of the stroke in the expulsion phase it comes into contact with a projection which enters said countersink by leaning on the sleeve and taking advantage of its elastic deformation properties to remove a small volume inside the sleeve and restore it when the outlet mouth begins to move back to the rest position thus causing a vacuum allowing the product located outside the cap to be sucked on the lips of the slot .

En plus, le dispositif de distribution est agencé de sorte que pendant la phase de retour la bouche de sortie est en communication avec une chambre munie d'une soupape isolant la chambre du reste du dispositif de distribution ce qui assure une diminution de la pression dans ladite chambre par rapport à la pression pendant l'expulsion du produit et permettant d'amplifier ainsi la dépression dans la bouche de sortie fermant hermétiquement la fente et aspirant l'éventuelle goutte du produit qui aurait pu rester à l'extérieur.In addition, the dispensing device is arranged so that during the return phase the outlet mouth is in communication with a chamber provided with a valve isolating the chamber from the rest of the dispensing device which ensures a reduction in the pressure in said chamber with respect to the pressure during the expulsion of the product and thus making it possible to amplify the depression in the outlet mouth hermetically closing the slot and aspirating the possible drop of the product which could have remained outside.

D'autres variantes d'exécution peuvent être utilisées pour arriver au même résultat.Other execution variants can be used to achieve the same result.

L'invention sera décrite plus en détail à l'aide du dessin annexé.The invention will be described in more detail using the attached drawing.

La figure unique est une vue latérale en coupe d'un distributeur selon l'invention.The single figure is a side sectional view of a dispenser according to the invention.

Le distributeur comprend une partie inférieure 1 et une partie supérieure 2. La partie supérieure 2 est formée d'une coquille essentiellement en deux parties, une partie 2a destinée à être fixée contre la paroi du local dans lequel le distributeur est destiné à être utilisé et une deuxième partie 2b amovible pour permettre la mise en place dans le distributeur d'un emballage 3 contenant le produit à distribuer. La partie 2b est munie d'une fenêtre f se trouvant sur sa partie inférieure pour permettre un contrôle visuel de la quantité du produit restant à l'intérieur de l'emballage 3.The dispenser comprises a lower part 1 and an upper part 2. The upper part 2 is formed from a shell essentially in two parts, a part 2a intended to be fixed against the wall of the room in which the distributor is intended to be used and a second removable part 2b to allow the installation in the dispenser of a package 3 containing the product to be dispensed. Part 2b is provided with a window f located on its lower part to allow visual control of the quantity of the product remaining inside the packaging 3.

La partie inférieure 1 comprend essentiellement un corps 4 destiné à abriter le dispositif de dosage et d'expulsion du produit et elle peut également être munie de moyens pour être fixée contre la paroi. L'emballage 3 contenant le produit est disposé dans un logement 5, en principe cylindrique, muni dans certains cas d'un dispositif 6 pour provoquer la perforation du bouchon fermant l'emballage 3. Le logement 5 communique avec une chambre inférieure 7 qui de son côté est en communication avec une première chambre cylindrique 8 dont l'extrémité communiquant avec la chambre 7 est fermée par une bille 9 poussée contre l'orifice de sortie de ladite chambre 8 par un ressort 10 qui s'appuye de l'autre côté contre un épaulement d'un piston creux 11. Une extrémité du piston 11 se déplace de manière étanche à l'intérieur de la chambre 8 grâce à une garniture d'étanchéité 12. Le piston creux 11 se trouve à l'intérieur d'un logement 13 du corps 4. Le piston creux 11 présente, à environ mi-longueur, un épaulement extérieur 14 contre lequel s'appuye un ressort 15 son autre extrémité s'appuyant contre un autre épaulement 29 extérieur de la chambre 8. Le ressort 14 a pour but de tirer le piston creux à l'extérieur de la chambre 8.The lower part 1 essentially comprises a body 4 intended to house the device for dosing and expelling the product and it can also be provided with means for being fixed against the wall. The packaging 3 containing the product is placed in a housing 5, in principle cylindrical, provided in some cases with a device 6 to cause the perforation of the plug closing the packaging 3. The housing 5 communicates with a lower chamber 7 which its side is in communication with a first cylindrical chamber 8 whose end communicating with the chamber 7 is closed by a ball 9 pushed against the outlet orifice of said chamber 8 by a spring 10 which is supported on the other side against a shoulder of a hollow piston 11. One end of the piston 11 moves in leaktight manner inside the chamber 8 by means of a seal 12. The hollow piston 11 is located inside a housing 13 of the body 4. The hollow piston 11 has, at about mid-length, an external shoulder 14 against which a spring 15 bears, its other end pressing against another shoulder 29 outside the chamber 8. The spring 14 at for the purpose of pulling the hollow piston outside the chamber 8.

Le piston creux 18 est fermé à sa deuxième extrémité par un bouchon vissé 16 débouchant dans un alésage 17 qui continue par un autre alésage 18 de diamètre inférieur à celui de l'alésage 17. La communication entre les deux alésages est fermée par une bille 19 poussée contre l'épaulement 20, entre les deux alésages de diamètre différent, par un ressort 21 s'appuyant par son autre extrémité contre le bouchon 16. L'alésage 17 forme une chambre se terminant par une bouche de sortie formée par une projection tubulaire 22 coiffée par un manchon 23 dont l'extrémité inférieure est en forme de dôme et est munie d'une fente 24, qui de préférence est une fente cruciforme.The hollow piston 18 is closed at its second end by a screw plug 16 opening into a bore 17 which continues by another bore 18 of diameter smaller than that of bore 17. The communication between the two bores is closed by a ball 19 thrust against the shoulder 20, between the two bores of different diameter, by a spring 21 pressing at its other end against the plug 16. The bore 17 forms a chamber ending in an outlet mouth formed by a tubular projection 22 capped by a sleeve 23 whose lower end is dome-shaped and is provided with a slot 24, which preferably is a cruciform slot.

Un levier 25 articulé autour d'un axe 26 est lié au piston creux 11 de sorte que lorsque le levier est déplacé dans le sens de la flèche F, le piston creux se déplace dans le sens contraire c'est-à-dire à l'intérieur de la chambre 8. Il est à relever que la projection tubulaire 22 est munie d'une fraisure 27 tandis qu'environ dans le même plan horizontal la partie inférieure du distributeur est munie d'une saillie horizontale 28.A lever 25 articulated around an axis 26 is linked to the hollow piston 11 so that when the lever is moved in the direction of the arrow F, the hollow piston moves in the opposite direction, that is to say inside the chamber 8. It should be noted that the tubular projection 22 is provided with a countersink 27 while approximately in the same horizontal plane the lower part of the distributor is provided with a horizontal projection 28.

Le fonctionnement du distributeur est le suivant :The operation of the dispenser is as follows:

Par gravité, le produit se trouvant dans l'emballage 3, qui est par ailleurs muni d'un couvercle relativement lourd 3a pour pousser le produit vers le bas et l'empêcher de rester collé sur la paroi de l'emballage, vient dans la chambre 7. On supposera pour le moment que le dispositif d'expulsion du produit est déjà amorcé, c'est-à-dire que la chambre 8, les alésages 17 et 18 sont déjà remplis avec le produit à distribuer et nous reviendrons par la suite sur la manière d'amorcer le dispositif.By gravity, the product in the package 3, which is also provided with a relatively heavy cover 3a to push the product down and prevent it from sticking to the wall of the package, comes into the chamber 7. It will be assumed for the moment that the device for expelling the product is already primed, that is to say that the chamber 8, the bores 17 and 18 are already filled with the product to be dispensed and we will come back by the continued on how to boot the device.

En agissant sur le levier 25, le piston creux 11 se déplace à l'intérieur de la chambre 8 ce qui provoque une diminution du volume de ladite chambre et le produit qui s'y trouve est poussé en direction de la bille 19 provoquant son déplacement à l'encontre du ressort 21 permettant ainsi au produit de passer dans l'alésage 17 et pousser le produit qui s'y trouve dans la bouche 22 provoquant également une surpression dans cette partie qui a pour conséquence l'ouverture de la fente 24 laissant sortir une dose de produit. Ceci continue jusqu'à ce que le piston creux 11 vient s'appuyer contre la bille 9 ce qui coïncide avec la fin de la course ou l'expulsion du produit. Lorsque le piston creux 11 vient en fin de course, c'est-à-dire contre la bille 9, la projection 28 écrase partiellement le manchon 23 et a tendance de rentrer dans la fraisure 27 de la projection tubulaire 22. Ceci provoque la suppression d'une partie du volume intérieur du manchon 23 et lorsqu'on lâche le levier 25 le piston creux sous l'action du ressort 13 revient à sa position initiale, ce qui provoque la restitution du volume supprimé à l'intérieur du manchon créant ainsi une dépression à l'intérieur de la bouche de sortie permettant d'aspirer la petite quantité du produit qui est, peut-être, restée à proximité de la fente 24. Lors de la phase retour du piston creux 18, la chambre 8 retrouve ses dimensions initiales c'est-à-dire que l'on crée une dépression dans l'espace formé par la chambre 8 et l'alésage 17, ce qui provoque le retour de la bille 19 contre l'épaulement 20 fermant ainsi la communication des alésages 17 et 18 et dans ce cas la dépression créée dans l'espace 8, 18 provoque le retrait de la bille vers l'intérieur dudit espace laissant ainsi le produit se trouvant dans la chambre 7 de remplir à nouveau la chambre 8 jusqu'à ce qu'il y ait équilibre de pressions entre les deux côtés. Ainsi, le processus peut continuer. La dépression créée dans la chambre 17 amplifie celle créée dans le volume du manchon 23.By acting on the lever 25, the hollow piston 11 moves inside the chamber 8 which causes a reduction in the volume of said chamber and the product which is there is pushed towards the ball 19 causing its displacement against the spring 21 thus allowing the product to pass into the bore 17 and push the product which is there in the mouth 22 also causing an overpressure in this part which results in the opening of the slot 24 letting out a dose of product. This continues until the hollow piston 11 comes to rest against the ball 9 which coincides with the end of the stroke or the expulsion of the product. When the hollow piston 11 comes to the end of its travel, that is to say against the ball 9, the projection 28 partially crushes the sleeve 23 and tends to enter the countersink 27 of the tubular projection 22. This causes the suppression of a part of the interior volume of the sleeve 23 and when the lever 25 is released the hollow piston under the action of the spring 13 returns to its initial position, which causes the volume removed inside the sleeve to be restored, thus creating a vacuum inside the outlet mouth making it possible to suck up the small amount of product which has, perhaps, remained close to the slot 24. During the return phase of the hollow piston 18, the chamber 8 regains its initial dimensions, that is to say that a depression is created in the space formed by the chamber 8 and the bore 17, which causes the return of the ball 19 against the shoulder 20 thus closing the communication of the bores 17 and 18 and in this case the depression c created in the space 8, 18 causes the withdrawal of the ball towards the interior of said space thus leaving the product being in the chamber 7 to refill the chamber 8 until there is pressure balance between Both sides. So the process can continue. The depression created in the chamber 17 amplifies that created in the volume of the sleeve 23.

Pour amorcer le dispositif, le fonctionnement est le même sauf qu'au départ il y a uniquement de l'air dans les différentes parties et il convient d'actionner plusieurs fois le levier pour provoquer l'évacuation de l'air s'y trouvant et laisser rentrer le produit se trouvant dans la chambre 7. Pour arriver évidemment à ce résultat il faut compter avec des ajustages et une étanchéité de qualité.To start the device, the operation is the same except that at the start there is only air in the different parts and it is advisable to actuate the lever several times to cause the evacuation of the air therein. and allow the product in chamber 7 to enter. To achieve this result, of course, it is necessary to reckon with quality fittings and sealing.

Pour éviter que le piston creux 18 tourne autour de son axe, il est muni d'un ergot 30 guidé dans une rainure 31 du corps 4.To prevent the hollow piston 18 from rotating about its axis, it is provided with a lug 30 guided in a groove 31 in the body 4.

Claims (3)

Distributeur de produits visqueux, tel que du savon liquide ou pâteux, comprenant essentiellement une partie inférieure abritant un dispositif de distribution de doses du produit visqueux, à travers une bouche de sortie ayant la forme d'une projection tubulaire, actionné par un organe de commande et d'une coquille surmontant ladite partie inférieure agencée pour abriter le produit à distribuer en vrac ou dans un conditionnement adéquat, la bouche de sortie étant coiffée par un manchon perforé d'un matériau déformable élastiquement, caractérisé par le fait que le manchon est muni à l'extrémité de sortie en forme de dôme d'une fente fermée en position de repos du distributeur et s'ouvrant sous la pression conduisant à l'expulsion d'une dose du produit à distribuer, que la partie inférieure dudit distributeur et notamment le dispositif de distribution et la bouche de sortie coiffée de l'élément déformable élastiquement sont agencés de sorte que lorsque l'organe de commande arrive en fin de course, dans la phase d'expulsion du produit, un petit volume intérieur dudit élément déformable élastiquement est supprimé, ledit volume étant recréé lorsque l'organe de contrôle revient vers sa position initiale provoquant ainsi une dépression à l'intérieur dudit capuchon déformable élastiquement.Dispenser for viscous products, such as liquid or pasty soap, essentially comprising a lower part housing a device for dispensing doses of the viscous product, through an outlet mouth in the form of a tubular projection, actuated by a control member and a shell surmounting said lower part arranged to house the product to be dispensed in bulk or in an adequate packaging, the outlet mouth being capped by a sleeve perforated with an elastically deformable material, characterized in that the sleeve is provided at the dome-shaped outlet end of a slot closed in the dispenser rest position and opening under pressure leading to the expulsion of a dose of the product to be dispensed, than the lower part of said dispenser and in particular the dispensing device and the outlet mouth covered with the elastically deformable element are arranged so that when the organ ne command arrives at the end of the race, in the phase of expulsion of the product, a small internal volume of said elastically deformable element is deleted, said volume being recreated when the control member returns to its initial position thus causing depression at l inside said elastically deformable cap. Distributeur selon la revendication 1, caractérisé par le fait que ladite bouche de sortie est solidaire d'un élément animé d'un mouvement linéaire alterné se déplaçant dans un sens pendant la phase d'expulsion et dans le sens contraire pour le retour à la position de repos.Dispenser according to Claim 1, characterized in that the said outlet mouth is integral with an element animated by an alternating linear movement moving in one direction during the expulsion phase and in the opposite direction for returning to the position rest. Distributeur selon l'une des revendications 1 ou 2, caractérisé par le fait que le dispositif de distribution est agencé de sorte que pendant la phase de retour, la bouche de sortie est en communication avec une chambre munie d'une soupape isolant ladite chambre du reste du dispositif de distribution la pression dans ladite chambre étant inférieure à la pression pendant la phase d'expulsion permettant ainsi d'amplifier la dépression dans la bouche de sortie.
4. Distributeur selon la revendication 3, caractérisé par le fait que la projection tubulaire de la bouche de sortie est munie d'une fraisure coiffée également par le manchon en matériau déformable élastiquement, que la partie inférieure dudit distributeur est munie d'un élément saillant disposé et dimensionné de sorte que lorsque ledit élément déplaçable arrive en fin de course dans la phase de l'expulsion du produit ledit élément saillant rentre dans la fraisure en s'appuyant sur la surface extérieure dudit manchon et en le déformant élastiquement provoquant ainsi la suppression d'une partie du volume intérieur dudit manchon qui sera rétablie lorsque l'élément déplaçable se déplace vers sa position de repos.Distributor according to one of claims 1 or 2, characterized in that the distribution device is arranged so that during the return phase, the outlet mouth is in communication with a chamber provided with a valve isolating said chamber from rest of the distribution device, the pressure in said chamber being less than the pressure during the expulsion phase, thus making it possible to amplify the depression in the outlet mouth.
4. Distributor according to claim 3, characterized in that the tubular projection of the outlet mouth is provided with a countersink also capped by the sleeve of elastically deformable material, that the lower part of said distributor is provided with a projecting element arranged and dimensioned so that when said displaceable element reaches the end of its travel in the phase of expelling the product, said protruding element enters the countersink by pressing on the external surface of said sleeve and by deforming it elastically thus causing suppression a part of the interior volume of said sleeve which will be restored when the movable element moves towards its rest position.
