Description

L'invention concerne le domaine des distributeurs pour des produits à viscosité moyenne ou haute, comme par exemple des produits cosmétiques de type gel ou crème, nécessitant d'être conservés à l'abri de l'air. L'invention concerne plus particulièrement un distributeur délivrant une dose de produit sur un plateau de présentation, par un trou réalisé dans ce plateau, le trou étant ensuite refermé de façon étanche.The invention relates to the field of dispensers for medium or high viscosity products, such as for example gel or cream-type cosmetic products, which need to be kept safe from the air. The invention relates more particularly to a dispenser delivering a dose of product on a presentation tray, through a hole made in this tray, the hole then being closed sealingly.

Certains produits cosmétiques utilisés, par exemple, sous forme de gel ou de pâte, de haute viscosité, doivent être conservés à l'abri de l'air pour ne pas se détériorer. La demande de brevet WO 2005/087618 enseigne un distributeur avec une valve de distribution étanche permettant de maintenir un produit de viscosité moyenne à haute, à l'abri de l'air. La demande de brevet WO 2005/087618 enseigne en particulier une valve disposée dans un plateau concave pour recueillir le produit expulsé. Cependant ce type de distributeur nécessite un agencement complexe de nombreux éléments de taille réduite. De plus ce document enseigne une activation complexe de la valve étanche par une liaison avec une deuxième valve de commande d'une ouverture d'alimentation communiquant avec un réservoir.Certain cosmetic products used, for example in the form of gel or paste, of high viscosity, must be kept away from the air so as not to deteriorate. The patent application WO 2005/087618 teaches a dispenser with a sealed dispensing valve to maintain a product of medium to high viscosity, protected from air. The patent application WO 2005/087618 teaches in particular a valve disposed in a concave tray to collect the expelled product. However, this type of dispenser requires a complex arrangement of many elements of reduced size. In addition this document teaches a complex activation of the sealed valve by a connection with a second control valve of a supply opening communicating with a reservoir.

L'invention va être décrite en référence aux figures précédemment citées. Un produit liquide de viscosité moyenne à haute, comme par exemple un produit cosmétique de type gel ou crème, devant être conservé à l'abri de l'air, est stocké dans un réservoir (2) de contenance variable correspondant à la quantité de produit stocké. Le brevet US 5,152,434 décrit par exemple un tel réservoir dans une pompe avec un premier piston limitant une chambre de pompage alimentée par un réservoir disposé dans un cylindre et limité par un deuxième piston mobile. De manière non limitative, un piston (23) mobile est disposé en face d'une ouverture (22) d'alimentation en liquide, et coulisse dans un cylindre (24), le cylindre (24) et le piston (23) délimitant le réservoir (2). Le réservoir (2) alimente une chambre (1) de pompage par une ouverture (22) d'alimentation à clapet (21) anti-retour. Le clapet (21) anti-retour empêche le produit liquide de circuler de la chambre (1) de pompage vers le réservoir (2) et autorise une circulation (F1) de liquide du réservoir (2) vers la chambre (1), comme représenté à la figure 1. De manière non limitative, le clapet (21) anti-retour comprend une bille ou un pointeau venant contre un bord tronconique de l'ouverture (22) d'alimentation en liquide ou une membrane venant boucher l'ouverture (22) d'alimentation en liquide ou un autre élément d'obstruction de l'ouverture d'alimentation, des éléments de maintien de l'élément d'obstruction étant, par exemple, disposés dans la chambre (1), en face de l'ouverture (22) d'alimentation.The invention will be described with reference to the figures mentioned above. A liquid product of medium to high viscosity, such as for example a cosmetic product of gel or cream type, which must be kept out of the air, is stored in a reservoir (2) of variable capacity corresponding to the quantity of product stored. The patent US 5,152,434 describes for example such a reservoir in a pump with a first piston limiting a pumping chamber fed by a reservoir disposed in a cylinder and limited by a second movable piston. In a nonlimiting manner, a movable piston (23) is disposed opposite a liquid supply opening (22) and slides in a cylinder (24), the cylinder (24) and the piston (23) delimiting the tank (2). The reservoir (2) supplies a pumping chamber (1) through a non-return valve feed opening (22). The non-return valve (21) prevents the liquid product from circulating from the pumping chamber (1) to the reservoir (2) and allows a circulation (F1) of liquid from the reservoir (2) to the chamber (1), as represented at figure 1 . Without limitation, the non-return valve (21) comprises a ball or a needle against a frustoconical edge of the opening (22) for supplying liquid or a membrane that closes the opening (22) supply in liquid or another obstruction element of the feed opening, holding elements of the obstruction element being, for example, arranged in the chamber (1), in front of the opening (22). power.

Le liquide est aspiré dans la chambre (2) par l'ouverture (22) d'alimentation, puis le liquide est expulsé (F3) de la chambre (2) de pompage par une ouverture (31) de distribution réalisée dans un plateau (3) de distribution, comme représenté à la figure 2. Une ou plusieurs cloisons (11, 12, 14, 37) entourant la chambre réalisent une jonction étanche entre l'ouverture (22) d'alimentation et l'ouverture (31) de distribution. Une dose (G) de produit disposée sur une surface (S3) de distribution du plateau (3), est ainsi disponible pour un utilisateur. De manière non limitative, la surface (S3) supérieure du plateau (3) de distribution est concave ou droite, le distributeur étant, par exemple, positionné avec sa surface (S3) de distribution vers le haut.The liquid is sucked into the chamber (2) through the feed opening (22), then the liquid is expelled (F3) from the pumping chamber (2) through a dispensing aperture (31) made in a tray ( 3) of distribution, as shown in figure 2 . One or more partitions (11, 12, 14, 37) surrounding the chamber provide a tight junction between the opening (22) for supply and the opening (31) for distribution. A dose (G) of product placed on a distribution surface (S3) of the tray (3) is thus available to a user. In a nonlimiting manner, the upper surface (S3) of the distribution plate (3) is concave or straight, the dispenser being, for example, positioned with its distribution surface (S3) upwards.

Lors d'une aspiration (F1) du liquide contenu dans le réservoir (2), dans la chambre (1) de pompage, le volume du réservoir (2) diminue de façon à ce que sa contenance corresponde au volume de liquide contenu. Le piston (23) avance (F2), par exemple, vers l'ouverture (22) d'alimentation au fur et à mesure que le liquide est aspiré dans la chambre (1) de pompage. Comme représenté à la figure 1, l'aspiration (F1) de liquide dans la chambre (1) par l'ouverture (22) est réalisée lors d'une expansion de la chambre (1). La chambre (1) étant formée en partie par une cloison (11) déformable, l'expansion de la chambre est due, par exemple, à un mouvement (M1) d'extension de la cloison (11) déformable. De manière non limitative, le volume maximum de la chambre correspond à une position au repos ou partiellement comprimée de la cloison (11) déformable. Lors d'une expansion de la chambre, le liquide sortant du réservoir (2) repousse le clapet (21) anti-retour et provoque un mouvement (F2) de remontée du piston (231) dans le cylindre (24). Le réservoir ne contenant pas d'air et la chambre (1) de pompage étant entièrement remplie de produit liquide, le produit liquide à distribuer n'entre en contact avec l'air qu'à sa sortie par l'ouverture (31) de distribution. De manière non limitative, le réservoir se vide jusqu'à ce que le piston (23) vienne en appui contre l'ouverture (22) d'alimentation. De manière non limitative, le piston (23) délimitant le réservoir, comprend sur sa face disposée vers l'extérieur, un moyen d'accrochage, comme par exemple un trou (231) fileté, permettant d'accrocher une tige filetée pour tirer le piston (23) hors du cylindre (24) pour remplir de nouveau le réservoir (2).During a suction (F1) of the liquid contained in the reservoir (2), in the chamber (1) for pumping, the volume of the reservoir (2) decreases so that its capacity corresponds to the volume of liquid contained. The piston (23) advances (F2), for example, towards the opening (22) of supply as the liquid is sucked into the chamber (1) pumping. As represented in figure 1 , the suction (F1) of liquid in the chamber (1) through the opening (22) is performed during an expansion of the chamber (1). The chamber (1) being formed in part by a deformable partition (11), the expansion of the chamber is due, for example, to a movement (M1) of extension of the partition (11) deformable. Without limitation, the maximum volume of the chamber corresponds to a position at rest or partially compressed of the partition (11) deformable. During an expansion of the chamber, the liquid exiting the tank (2) pushes the check valve (21) and causes a movement (F2) up the piston (231) in the cylinder (24). Since the tank does not contain air and the chamber (1) for pumping is completely filled with liquid product, the liquid product to be dispensed comes into contact with the air only when it leaves the opening (31) of distribution. Without limitation, the reservoir empties until the piston (23) bears against the opening (22) supply. In a nonlimiting manner, the piston (23) defining the reservoir, comprises on its outwardly facing face, a hooking means, such as a threaded hole (231), for hanging a threaded rod to pull the piston (23) out of the cylinder (24) to refill the tank (2).

La cloison déformable (11), dont la paroi intérieure forme en partie la chambre (1) de pompage, est disposée dans un espace (30) de rangement du distributeur. La cloison déformable est par exemple fixée à des cloisons rigides de la pompe ou fait partie d'une pièce, comme par exemple une cloche élastique déformable, comprise dans la pompe. De manière non limitative, l'espace (30) de rangement, par exemple de forme cylindrique, s'étend au dessus d'une cloison inférieure dans laquelle est réalisée l'ouverture (22) d'alimentation. La cloison inférieure, de manière non limitative, commune au cylindre du réservoir, réalise, par exemple, une paroi (37) inférieure de la chambre (1) de pompage. La cloison inférieure est, par exemple, prolongée à sa périphérie, par une cloison (35) latérale. De manière non limitative, la cloison (35) latérale est de section circulaire, arrondie ou angulaire formant par exemple un polygone comme un carré, un hexagone ou un octogone. L'espace (30) de rangement est, par exemple, fermé sur le dessus, par le plateau (3) de distribution. De manière non limitative, le plateau est mobile pour être pressé par un utilisateur ou un bouton (38) poussoir est réalisé dans le plateau (3). Un appui sur le plateau ou le bouton, en liaison avec la cloison déformable, déforme et comprime (M2) la cloison déformable pour réduire le volume de la chambre et expulser le produit liquide par l'ouverture de distribution.The deformable partition (11), whose inner wall partially forms the chamber (1) for pumping, is arranged in a space (30) for storing the dispenser. The deformable partition is for example fixed to rigid walls of the pump or part of a room, such as a deformable elastic bell, included in the pump. In a nonlimiting manner, the storage space (30), for example of cylindrical shape, extends above a lower partition in which the opening (22) of supply is made. The lower partition, in a nonlimiting manner, common to the cylinder of the reservoir, carries out, for example, a wall (37) of the lower chamber (1) pumping. The lower partition is, for example, extended at its periphery by a partition (35) side. In a nonlimiting manner, the partition (35) side is circular, rounded or angular section forming for example a polygon such as a square, a hexagon or an octagon. The storage space (30) is, for example, closed on the top by the distribution tray (3). Without limitation, the plate is movable to be pressed by a user or a push button (38) is formed in the plate (3). A support on the plate or the button, in connection with the deformable partition, deforms and compresses (M2) the deformable partition to reduce the volume of the chamber and expel the liquid product through the dispensing opening.

La cloison déformable est, par exemple réalisée par une partie (11) bombée déformable et élastique, d'une cloche (11, 12, 13, 14) dans laquelle est réalisée en partie, la chambre (1) de pompage. La cloche est maintenue, par des moyens de liaison, dans l'espace (30) de rangement. La cloche comprend par exemple, un anneau (13) rigide en appui contre une paroi (36, 351) latérale de l'espace (30) de rangement. La paroi latérale d'appui contre l'anneau (13) de maintien de la cloche, est par exemple la paroi (351) latérale délimitant l'espace (30) de rangement ou une paroi (36) réalisée par un anneau cylindrique prolongeant la paroi (37) inférieure de l'espace (30) de rangement, comme représenté à la figure 3. Cet anneau d'appui, de diamètre intérieur correspondant au diamètre extérieur de l'anneau (13) d'appui, est par exemple disposé autour de l'ouverture (22) d'alimentation. De manière non limitative, l'anneau rigide de maintien est, par exemple, prolongé d'un côté par la partie (11) bombée élastique et de l'autre côté, par une lèvre (14) d'étanchéité en appui contre la surface (37) inférieure, autour de l'ouverture (22) d'alimentation. La partie (11) bombée se prolonge, de manière non limitative, par un tube (11) ou un conduit de liaison avec le plateau (3), débouchant en face de l'ouverture (31) de distribution.The deformable partition is, for example made by a portion (11) curved deformable and elastic, a bell (11, 12, 13, 14) in which is formed in part, the chamber (1) pumping. The bell is maintained by connecting means in the storage space (30). The bell comprises, for example, a rigid ring (13) bearing against a side wall (36, 351) of the storage space (30). The side wall bearing against the ring (13) for holding the bell, is for example the side wall (351) delimiting the storage space (30) or a wall (36) formed by a cylindrical ring extending the wall (37) of the storage space (30) as shown in FIG. figure 3 . This support ring, of internal diameter corresponding to the outer diameter of the ring (13) of support, is for example arranged around the opening (22) of supply. In a nonlimiting manner, the rigid retaining ring is, for example, extended on one side by the elastic convex portion (11) and on the other side by a sealing lip (14) bearing against the surface. (37) below, around the feed opening (22). The curved portion (11) is extended, without limitation, by a tube (11) or a connecting duct with the plate (3), opening opposite the opening (31) of distribution.

Le tube, par exemple de section transversale circulaire, est inséré dans un logement (39) du plateau (3) serré autour du tube (12) rigide et maintenant le tube (11) avec le plateau (3) de distribution.The tube, for example of circular cross section, is inserted into a housing (39) of the plate (3) clamped around the rigid tube (12) and holding the tube (11) with the distribution plate (3).

Selon un autre exemple, comme représenté à la figure 10, un conduit à soufflets ou en accordéon, déformable, est fixé, par exemple, par collage, au plateau de distribution.In another example, as shown in figure 10 , a duct bellows or accordion, deformable, is fixed, for example, by gluing, to the distribution tray.

Selon un autre mode de réalisation, la cloche comprend un anneau (15) inférieur, fixé, par exemple par collage, contre la paroi (37) inférieure ou latérale de l'espace (30) de rangement et autour de l'ouverture (22) d'alimentation. A l'opposé de la paroi (37) inférieure, l'anneau (15) collé se prolonge de même que précédemment décrit, par la partie (11) bombée déformable et élastique et par le tube ou le conduit à soufflets.According to another embodiment, the bell comprises a lower ring (15) fixed, for example by gluing, against the lower or side wall (37) of the storage space (30) and around the opening (22). ) power supply. Opposite the lower wall (37), the glued ring (15) is extended as previously described, by the portion (11) curved deformable and elastic and the tube or the duct bellows.

Un élément (32) d'étanchéité élastique et déformable, disposé sur le plateau (3) ou lié à la pièce formant la chambre déformable, ferme ou ouvre l'ouverture (31) de sortie. L'élément d'étanchéité, par exemple, disposé sur le plateau, a une épaisseur (H32) maximum déterminée et une surface d'appui déterminée supérieure à la section transversale de l'ouverture (31) de distribution. De manière non limitative, la surface d'appui de l'élément d'étanchéité est ronde, ovale, arrondie ou anguleuse, formant par exemple un polygone comme un carré, un hexagone ou un octogone. L'élément d'étanchéité disposé sur le plateau, comme par exemple un disque en matière plastique souple et déformable, comprend au moins un point (321) de fixation avec le plateau (3) et au moins une partie (322) mobile s'écartant de l'ouverture (31) pour laisser sortir du produit liquide. L'élément (32) élastique d'étanchéité est, par exemple, disposé sur le plateau (3), de manière non limitative, dans un renfoncement (320) de profondeur (H3) déterminée supérieure à l'épaisseur (H32) de l'élément d'étanchéité, de façon à ce que l'élément d'étanchéité, en position fermée, ne dépasse pas au dessus de la surface (S3) supérieure du plateau (3) de distribution. Le renfoncement a aussi une section transversale englobant la surface de l'élément d'étanchéité.An elastic and deformable sealing element (32), placed on the plate (3) or connected to the part forming the deformable chamber, closes or opens the outlet opening (31). The sealing element, for example, arranged on the plate, has a maximum thickness (H32) determined and a specific bearing surface greater than the cross section of the opening (31) distribution. In a nonlimiting manner, the bearing surface of the sealing element is round, oval, rounded or angular, forming for example a polygon such as a square, a hexagon or an octagon. The sealing element disposed on the plate, such as for example a flexible and deformable plastic disc, comprises at least one attachment point (321) with the plate (3) and at least one moving part (322). away from the opening (31) to let liquid product out. The elastic sealing element (32) is, for example, arranged on the plate (3), in a nonlimiting manner, in a recess (320) of depth (H3) determined greater than the thickness (H32) of the sealing element, so that the sealing element, in the closed position, does not protrude above the upper surface (S3) of the distribution plate (3). The recess also has a cross section encompassing the surface of the sealing member.

Selon un autre exemple, l'élément d'étanchéité est lié à un conduit prolongeant la paroi déformable, l'élément d'étanchéité étant en retrait par rapport à la surface supérieure du plateau.In another example, the sealing element is connected to a duct extending the deformable wall, the sealing element being set back relative to the upper surface of the plate.

Par ses propriétés élastiques, l'élément d'étanchéité revient en position de fermeture de l'ouverture (31) de distribution, plaqué autour du bord de l'ouverture, après le passage du produit liquide. L'élément d'étanchéité est par exemple fixé par collage ou par serrage. Le plateau (3) ou respectivement l'élément (32) d'étanchéité comprend, par exemple, un téton (324) saillant venant s'insérer dans un trou de serrage réalisé dans l'élément (32) d'étanchéité ou respectivement dans le plateau (3).By its elastic properties, the sealing member returns to the closed position of the dispensing opening (31), plated around the edge of the opening, after the passage of the liquid product. The sealing element is for example fixed by gluing or clamping. The plate (3) or respectively the sealing element (32) comprises, for example, a pin (324) protruding from being inserted into a clamping hole made in the sealing element (32) or respectively in the tray (3).

L'utilisateur en passant ses doigts le long de la surface (S3) de distribution passe sur l'élément (32) d'étanchéité, sans buter contre l'élément (32) d'étanchéité et ne risque pas, par exemple, d'ouvrir accidentellement l'ouverture de distribution, maintenant ainsi le produit, comme par exemple du gel, à l'abri de l'air. L'élément (32) d'étanchéité, disposé dans le renfoncement (320), a ainsi un aspect extérieur continu avec la surface (S3) supérieure du plateau (3) de distribution. Le plaquage, en position fermée, de l'élément (32) d'étanchéité est assuré par ses propriétés élastiques et par l'aspiration dans la chambre (1) de pompage.The user passing his fingers along the distribution surface (S3) passes over the sealing element (32), without abutting against the sealing element (32) and does not risk, for example, accidentally open the dispensing opening, thus keeping the product, such as gel, away from the air. The sealing element (32), disposed in the recess (320), thus has a continuous external appearance with the upper surface (S3) of the distribution plate (3). Plating, in the closed position, the sealing element (32) is ensured by its elastic properties and by the suction in the chamber (1) pumping.

La figure 5 représente, par exemple, un disque (32a) comprenant une première zone (321a) fixée, par exemple par collage, au plateau (3) et une deuxième zone (322b) mobile en appui sur une surface d'appui du plateau (3). La première et la deuxième zone entourent une troisième zone (322a) mobile du disque (32a) disposée en face de l'ouverture (31) de distribution.The figure 5 represents, for example, a disk (32a) comprising a first zone (321a) fixed, for example by gluing, to the plate (3) and a second zone (322b) movable resting on a bearing surface of the plate (3) . The first and second zones surround a third movable area (322a) of the disc (32a) disposed opposite the dispensing aperture (31).

La figure 6 représente un exemple de disque (32b) fendu comprenant une zone (321 b) périphérique fixée, par exemple par collage, au plateau (3). De manière non limitative, les fentes (3200) séparent le disque (32b) fendu qui comprend des parties centrales mobiles venant obturer l'ouverture de distribution et en appui contre un croisillon disposé transversalement à l'ouverture (31) de distribution du plateau (3), comme représenté à la figure 6bis. Chaque partie mobile du disque (32b) fendu comprend une zone (322d) venant contre un ou plusieurs bras (325) et une zone (322c) d'obturation d'un passage pour le produit liquide. De manière non limitative, le disque comprend par exemple deux fentes (3200) passant par le centre du disque (32b) fendu, séparant la partie mobile du disque en quatre parties en appui sur un ou plusieurs bras (325) d'un croisillon à quatre bras. Le nombre de bras (325) de supports est, par exemple, égal au nombre de parties mobiles séparées du disque (32b) fendu. Les bras (325) de support sont disposés, par exemple avec leur surface supérieure d'appui dans le même plan que la surface (326) de fixation du plateau (3) avec le disque (32b).The figure 6 represents an example of a split disk (32b) comprising a peripheral zone (321b) fixed, for example by gluing, to the plate (3). In a nonlimiting manner, the slots (3200) separate the split disc (32b) which comprises movable central parts closing the dispensing opening and resting against a crosspiece arranged transversely to the dispensing aperture (31) of the tray ( 3), as shown in figure 6bis . Each movable portion of the slotted disk (32b) comprises a zone (322d) against one or more arms (325) and a zone (322c) for closing a passage for the liquid product. In a nonlimiting manner, the disk comprises for example two slots (3200) passing through the center of the disc (32b) split, separating the movable portion of the disk in four parts resting on one or more arms (325) of a spider. four arms. The number of media arms (325) is, for example, equal to the number of separate moving parts of the split disk (32b). The support arms (325) are arranged, for example with their upper bearing surface in the same plane as the surface (326) for fixing the plate (3) with the disk (32b).

Selon une variante de réalisation, comme représenté à la figure 4, la partie mobile de l'élément d'étanchéité venant en appui contre le plateau (3), s'appuie contre une arrête (323) saillante du plateau (3). L'élément d'étanchéité, comme par exemple un disque souple et déformable, se déforme légèrement au contact de l'arrête pour améliorer l'étanchéité en position de fermeture de l'ouverture (31) de distribution. L'effort de pression de l'élément (32) d'étanchéité contre le plateau est dû notamment à son élasticité et au phénomène d'aspiration dans la chambre (1) de pompage.According to an alternative embodiment, as shown in FIG. figure 4 the moving part of the sealing element bearing against the plate (3) bears against a protruding edge (323) of the plate (3). The sealing element, such as for example a flexible and deformable disk, deforms slightly in contact with the edge to improve the watertightness. closing position of the dispensing aperture (31). The pressure force of the element (32) sealing against the plate is due in particular to its elasticity and suction phenomenon in the chamber (1) pumping.

Selon une variante de réalisation, l'élément d'étanchéité prolongeant la pièce déformable formant, en partie, la chambre (1) de pompage, comprend une surface supérieure fendue et bombée vers l'extérieur, comme représenté à la figure 11. Les fentes réalisent, par exemple, des parties s'ouvrant vers l'extérieur ou restant serrées ensemble, de façon étanche, au repos.According to an alternative embodiment, the sealing element extending the deformable part forming, in part, the chamber (1) for pumping, comprises an upper surface slotted and curved outwards, as shown in FIG. figure 11 . The slots provide, for example, portions opening outward or remaining tight together, tightly, at rest.

Pour distribuer une dose (G) de produit liquide, comme par exemple du gel ou de la crème, sur la surface (S3) supérieure du plateau (3) de distribution, l'utilisateur exerce une pression sur le dispositif de distribution par un moyen de pression pour comprimer (M2) la cloison déformable et réduire le volume de la chambre (1) de pompage. Le produit liquide sort alors en repoussant l'élément (32) d'étanchéité, comme représenté à la figure 2. L'utilisateur appuie par exemple sur la surface supérieure (S3) du plateau (3) mobile ou sur un bouton (38) poussoir aménagé dans le plateau (3) mobile ou fixe. Le dispositif de distribution est ensuite ramené dans sa position initiale par élasticité, la cloison déformable reprenant sa forme initiale, par extension (M1) de la cloison déformable. Une expansion de la chambre (1) de pompage provoque alors une aspiration dans la chambre de pompage et plaque l'élément (32) d'étanchéité contre le bord de l'ouverture (31) de distribution fermée de façon étanche. Le phénomène d'aspiration et les propriétés élastiques de l'élément d'étanchéité tendent à ramener l'élément d'étanchéité en position de fermeture de l'ouverture de distribution, lors d'une aspiration (F1) dans la chambre (1) de pompage, comme représenté à la figure 1.In order to dispense a dose (G) of liquid product, for example gel or cream, onto the upper surface (S3) of the distribution tray (3), the user exerts pressure on the dispensing device by means pressure device for compressing (M2) the deformable partition and reducing the volume of the chamber (1) for pumping. The liquid product then exits by pushing the sealing member (32) as shown in FIG. figure 2 . The user presses for example on the upper surface (S3) of the plate (3) movable or on a button (38) pusher arranged in the plate (3) movable or fixed. The dispensing device is then returned to its initial position by elasticity, the deformable partition returning to its original shape, by extension (M1) of the deformable partition. An expansion of the pumping chamber (1) then causes suction in the pumping chamber and plates the sealing member (32) against the edge of the sealingly closed dispensing opening (31). The suction phenomenon and the elastic properties of the sealing element tend to bring the sealing element back into the closed position of the dispensing opening during a suction (F1) in the chamber (1). pumping, as shown in figure 1 .

De manière non limitative, comme représenté à la figure 2, la cloison déformable est comprimée par une pression de l'utilisateur sur la surface supérieure (S3) du plateau (3) de présentation. La force de compression (M2) exercée par l'utilisateur, est, par exemple, transmise par le plateau (3) directement sur la cloison déformable ou au tube (12) rigide prolongeant la cloison déformable, le tube (12) rigide exerçant une force de compression sur la cloison (11) élastique déformable qui est comprimée, la chambre (1) de pompage étant alors réduite. Lorsque l'utilisateur n'exerce plus sa pression, la partie déformable se déforme en extension, par élasticité et repousse le plateau ou le tube.In a non-limiting way, as shown in FIG. figure 2 , the deformable partition is compressed by a pressure of the user on the upper surface (S3) of the tray (3) presentation. The compression force (M2) exerted by the user is, for example, transmitted by the plate (3) directly to the deformable partition or to the rigid tube (12) extending the deformable partition, the rigid tube (12) exerting a compressive force on the deformable elastic partition (11) which is compressed, the chamber (1) pumping being reduced. When the user no longer exerts his pressure, the deformable part deforms in extension, by elasticity and pushes the tray or the tube.

Selon une variante de réalisation, la cloison déformable comprend une ouverture prolongée par un conduit (120) à soufflets, déformable, de rigidité supérieure à la rigidité de la cloison (11) déformable, comme représenté à la figure 10. Ce conduit (120) à soufflets est, par exemple, serti dans un logement (39) sous le plateau, pour déboucher en face de l'ouverture (31) de distribution dans le plateau (3). Le conduit (120) à soufflets de rigidité supérieure à la cloison (11) déformable, transmet par exemple un premier effort de pression sur la cloison déformable, puis l'augmentation de pression et d'application d'un deuxième effort de compression entraîne, par exemple, la déformation du conduit (120) à soufflets. De façon avantageuse, en dessous d'un effort de pression déterminé, la déformation du conduit (120) à soufflets est négligeable pour délivrer une première dose déterminée de liquide visqueux, comme par exemple du gel. L'application d'un effort de pression supérieur permet alors la déformation du conduit (210) à soufflets juste après la déformation de la cloison (11) déformable. La déformation est alors plus importante et réalise une réduction plus importante de la chambre et pour augmenter la dose de produit liquide distribué.According to an alternative embodiment, the deformable partition comprises an extended opening by a duct (120) with bellows, deformable, of rigidity greater than the rigidity of the partition (11) deformable, as shown in FIG. figure 10 . This duct (120) bellows is, for example, crimped into a housing (39) under the tray, to open in front of the opening (31) of distribution in the tray (3). The duct (120) with bellows of greater rigidity than the partition (11) deformable, for example transmits a first pressure force on the deformable partition, then the increase in pressure and application of a second compression force causes, for example, the deformation of the bellows conduit (120). Advantageously, below a determined pressure force, the deformation of the conduit (120) bellows is negligible to deliver a first determined dose of viscous liquid, such as gel. The application of a higher pressure force then allows the deformation of the duct (210) bellows just after the deformation of the partition (11) deformable. The deformation is then greater and achieves a greater reduction of the chamber and to increase the dose of liquid product dispensed.

Selon une variante de réalisation, la cloison (11) déformable comprend une ouverture prolongée par un tube (121) souple en liaison avec l'élément d'étanchéité et maintenu, par exemple par collage ou par serrage, dans un passage du plateau de distribution, comme représenté à la figure 11. De façon avantageuse, une pression sur le plateau de distribution provoque la déformation de la pièce comprenant le tube (121) souple et déforme en particulier le bord supérieur du tube. La déformation du bord supérieur du tube (121) souple implique alors une ouverture de l'élément (32) d'étanchéité. De manière non limitative, la surface inférieure du plateau vient contre la cloison (11) déformable. De manière non limitative, une seule pièce réalise la chambre étanche entre l'ouverture (22) d'alimentation et l'ouverture (31) de distribution.According to an alternative embodiment, the deformable partition (11) comprises an extended opening through a flexible tube (121) in connection with the sealing element and held, for example by gluing or clamping, in a passage of the distribution plate. as shown in figure 11 . Advantageously, pressure on the distribution plate causes deformation of the part comprising the flexible tube (121) and deforms in particular the upper edge of the tube. The deformation of the upper edge of the flexible tube (121) then implies an opening of the sealing element (32). In a nonlimiting manner, the lower surface of the plate comes against the partition (11) deformable. Without limitation, a single piece realizes the sealed chamber between the opening (22) for supply and the opening (31) of distribution.

Selon un exemple de réalisation, comme représenté à la figure 3, le plateau (3) est lié, par sa face inférieure, à des pattes (301) souples élastiques en appui sur la cloison (11) déformable, par exemple bombée, ou sur une paroi de l'espace (30) de rangement. La pression exercée par l'utilisateur est transmise en partie par les pattes (301) flexibles élastiques qui exercent, par exemple, un effort de compression sur la partie (11) bombée élastique de la cloison (11) déformable. Lors d'une aspiration, des pattes souples exercent un effort de retour en position initiale sur le plateau (3), les pattes souples étant, par exemple, en appui sur une paroi de l'espace (30) de rangement dans lequel est disposée la cloison (11) déformable.According to an exemplary embodiment, as shown in FIG. figure 3 , the plate (3) is linked, by its lower face, to resilient flexible lugs (301) resting on the deformable partition (11), for example curved, or on a wall of the storage space (30). The pressure exerted by the user is transmitted in part by the elastic flexible tabs (301) which exert, for example, a compressive force on the portion (11) curved elastic of the partition (11) deformable. During suction, flexible tabs exert a return force in initial position on the plate (3), the flexible tabs being, for example, resting on a wall of the storage space (30) in which is disposed the partition (11) deformable.

Selon un exemple de réalisation, le plateau (3) comprend sur sa face inférieure dirigée vers la cloison (11) déformable, des pattes (302) d'appui rigides venant contre la cloison (11) déformable, comme par exemple la partie (11) flexible élastique bombée d'une cloche, comme représenté à la figure 9. De manière non limitative, les pattes (302) d'appui rigides sont disposées contre la cloison bombée déformable et suivent la forme de la cloison au repos ou sont disposées en appui contre la cloison élastique déformable en partie comprimée dans la position de repos du dispositif de distribution, le plateau étant maintenu contre un élément de butée en hauteur, comme par exemple une bague (4) supérieure venant en appui sur la périphérie du plateau (3).According to an exemplary embodiment, the plate (3) comprises on its lower face directed towards the deformable partition (11), rigid support lugs (302) coming against the deformable partition (11), such as for example the part (11) ) curved elastic hose of a bell, as shown in figure 9 . In a nonlimiting manner, the rigid support lugs (302) are arranged against the deformable curved partition and follow the shape of the partition at rest or are placed in abutment against the deformable elastic partition partially compressed in the rest position of the device. distribution, the plate being held against a stop element in height, such as for example an upper ring (4) bearing on the periphery of the plate (3).

Selon un exemple de réalisation, de manière non limitative, la compression de la chambre de pompage est réalisée par un appui de l'utilisateur sur un bouton (38) poussoir mobile en translation par rapport au plateau (3). De manière non limitative, le bouton poussoir mobile en translation est associé au plateau (3) fixe ou mobile. Le bouton (38) poussoir comprend par exemple une patte (303) rigide d'appui contre la cloison déformable, comme par exemple la partie bombée d'une cloche. Le bouton (38) est par exemple guidé par une cloison (381) venant contre une surface d'appui (351) réalisée par une cloison (35) du dispositif de distribution ou le bouton (38) est guidé latéralement, par une surface (361) d'appui du plateau (3).According to an exemplary embodiment, in a non-limiting manner, the compression of the pumping chamber is performed by a user pressing a push button (38) movable in translation relative to the plate (3). In a nonlimiting manner, the push button movable in translation is associated with the fixed or movable plate (3). The push button (38) comprises for example a tab (303) rigid against the deformable wall, such as the curved portion of a bell. The button (38) is for example guided by a partition (381) coming against a bearing surface (351) made by a partition (35) of the dispensing device or the button (38) is guided laterally by a bearing surface (361) of the plate (3).

De manière non limitative, le plateau (3) mobile, recevant le bouton (38), permet aussi d'exercer une force de compression et comprend, de manière non limitative, une partie (362) de recouvrement d'une partie biseautée du bouton (38) poussoir, de façon à ce que l'appui sur le plateau (3) entraîne le bouton (38) et que lorsque l'utilisateur appuie seulement sur le bouton (38), le plateau (3) n'est pas déplacé. L'appui sur le bouton (38) poussoir entraîne par exemple la distribution d'une dose déterminée inférieure à la dose distribuée par un appui sur le plateau (3).Without limitation, the plate (3) movable, receiving the button (38), also allows to exert a compressive force and includes, but not limited to, a portion (362) covering a tapered portion of the button (38) pusher, so that the support on the plate (3) drives the button (38) and that when the user only presses the button (38), the plate (3) is not moved . Pressing the button (38) pushes for example the distribution of a determined dose less than the dispensed dose by pressing the plate (3).

De manière non limitative, le tube (12) ou le conduit à soufflets reliant le plateau (3) et la cloison déformable, comme par exemple la partie (11) bombée compressible de la cloche, est disposé en haut de la cloison déformable réalisée bombée, le tube ou le conduit étant centrée par rapport à la cloison bombée déformable, comme représenté à la figure 8, ou de façon décentrée, comme représenté à la figure 9.Without limitation, the tube (12) or the bellows duct connecting the plate (3) and the deformable partition, such as the portion (11) curved compressible bell, is disposed at the top of the deformable partition made convex , the tube or duct being centered with respect to the deformable curved partition, as shown in FIG. figure 8 , or off-center, as shown in figure 9 .

Selon une variante de réalisation non représentée, un tube central lié à la cloison déformable, débouche dans un passage réalisé centralement dans le plateau (3), le passage dans le plateau (3) traversant transversalement le plateau (3) et débouchant à la surface (S3) supérieure du plateau (3) dans une zone périphérique du plateau (3).According to an alternative embodiment not shown, a central tube connected to the deformable partition, opens into a passage made centrally in the plate (3), the passage in the plate (3) transversely traversing the plate (3) and opening on the surface (S3) upper plate (3) in a peripheral zone of the plate (3).

De manière non limitative, le plateau (3) de distribution est mobile et guidé en translation par rapport à la cloison (35) latérale réalisant l'espace (30) de rangement dans lequel est disposé la cloison déformable délimitant en partie la chambre. Selon un exemple de réalisation, le guidage est réalisé par une paroi latérale du plateau (3) ayant une surface d'appui contre une surface de guidage (351) d'une cloison du distributeur, comme représenté à la figure 9. La surface d'appui du plateau (3) venant, par exemple, contre une paroi de l'espace (30) de rangement, réalise un guidage en translation et permet de maintenir le plateau (3) pour conserver son orientation, le plateau étant par exemple à l'horizontal.In a nonlimiting manner, the distribution plate (3) is movable and guided in translation relative to the partition (35) side forming the space (30) storage in which is disposed the deformable partition partially delimiting the chamber. According to an exemplary embodiment, the guide is formed by a side wall of the plate (3) having a bearing surface against a guide surface (351) of a partition of the distributor, as shown in FIG. figure 9 . The support surface of the plate (3) coming, for example, against a wall of the storage space (30), provides a guide in translation and makes it possible to maintain the plate (3) to maintain its orientation, the plate being for example horizontally.

Selon un autre mode de réalisation, le plateau comprend des bords latéraux arrondis permettant une translation et une inclinaison par un pivotement du plateau (3). De manière non limitative, la surface (S3) supérieure du plateau (3) est en appui contre une bague (4) réalisant une butée en hauteur. La bague (4) est, par exemple, fixée par vissage et vient en appui contre une partie périphérique de la surface (S3) supérieure, pour limiter le déplacement du plateau (3) vers le haut. De manière non limitative, les pattes (301) flexibles, venant en appui contre la cloison déformable ou contre la paroi de l'espace (30) de rangement, permettent de réaliser un guidage du plateau et exercent une force s'ajoutant à la force de retour, vers la position non compressée de la cloison déformable, pour ramener le plateau en position initiale, par exemple à l'horizontale. De façon avantageuse, le plateau inclinable, en appui contre la bague (4) supérieure de limitation, permet à l'utilisateur d'exercer un bras de levier en appuyant d'un côté, à la périphérie du plateau, le plateau pivotant, en appui sur le côté opposé contre la bague (4) d'arrêt.According to another embodiment, the plate comprises rounded lateral edges allowing a translation and an inclination by a pivoting of the plate (3). Without limitation, the upper surface (S3) of the plate (3) is in abutment against a ring (4) providing a stop in height. The ring (4) is, for example, fixed by screwing and abuts against a peripheral portion of the upper surface (S3), to limit the displacement of the plate (3) upwards. In a nonlimiting manner, the flexible tabs (301) bearing against the deformable partition or against the wall of the storage space (30) make it possible to guide the plate and exert a force that is added to the force back to the uncompressed position of the deformable partition, to bring the tray to the initial position, for example horizontally. Advantageously, the tilting plate, bearing against the upper limiting ring (4), allows the user to exert a lever arm by pressing on one side, at the periphery of the plate, the pivoting plate, support on the opposite side against the ring (4) stop.

De façon avantageuse, la cloison déformable bombée, comme par exemple la partie (11) bombée déformable de la cloche, peut être compressée par des appuis en une pluralité de points. De plus, le plateau qui peut être laissé libre en rotation, permet d'exercer un appui minime, la force de pression étant mieux contrôlée par l'utilisateur que dans le cas d'une chambre de pompage réalisée avec un piston dans un cylindre. De plus le piston, selon l'art antérieur, doit être en liaison étanche avec le cylindre, contrairement à la présente invention où l'élément mobile, comme par exemple le plateau, ne nécessite pas une liaison étanche avec le cylindre. La disposition selon la présente invention, permet au contraire d'appuyer de plusieurs façons, avec une force différente, le plateau étant maintenu à plat ou une ou plusieurs rotations étant autorisées, par exemple pour l'inclinaison du plateau. La construction d'un dispositif de distribution selon l'invention offre ainsi de nombreuses possibilités avec peu de pièces pour la construction. De plus, le distributeur est réalisable en utilisant uniquement des matériaux en plastique, ce qui implique que la pompe est entièrement recyclable et résistante aux produits corrosifs. De façon avantageuse, la pièce comportant la cloison déformable, par exemple réalisée par moulage, permet de nombreuses formes, selon de nombreuses épaisseurs et selon différentes propriétés élastiques.Advantageously, the curved deformable partition, such as the deformable curved portion (11) of the bell, can be compressed by supports at a plurality of points. In addition, the plate which can be left free to rotate, allows to exert a minimal support, the pressure force being better controlled by the user than in the case of a pumping chamber made with a piston in a cylinder. In addition, the piston, according to the prior art, must be in sealed connection with the cylinder, unlike the present invention where the movable element, such as the tray, does not require a sealed connection with the cylinder. The arrangement according to the present invention allows on the contrary to support in several ways, with a different force, the plate being held flat or one or more rotations being allowed, for example for the inclination of the plate. The construction of a dispensing device according to the invention thus offers many possibilities with few parts for the construction. In addition, the dispenser is achievable using only plastic materials, which implies that the pump is fully recyclable and resistant to corrosive products. Advantageously, the part comprising the deformable partition, for example made by molding, allows many shapes, in many thicknesses and according to different elastic properties.

Il doit être évident pour les personnes versées dans l'art que la présente invention permet des modes de réalisation sous de nombreuses autres formes spécifiques sans l'éloigner du domaine d'application de l'invention comme revendiqué. Par conséquent, les présents modes de réalisation doivent être considérés à titre d'illustration, mais peuvent être modifiés dans le domaine défini par la portée des revendications jointes, et l'invention ne doit pas être limitée aux détails donnés ci-dessus.It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed.
