When the piston 16 returns into position, a new metered quantity of product passes from the primary chamber 3 into the secondary chamber 7, the non-return valve 12 preventing any air suction towards the inside of the box. <IMAGE>

Description

La présente invention a pour objet un dispositif pour le conditionnement et la distribution de produits pâteux ou liquides sous forme de gel ou d'émulsion comme par exemple des produits cosmétiques ou pharmaceutiques. Généralement pour conditionner de tels produits on utilise des tubes ou des pots. Les inconvénients liés à l'utilisation de tubes en plastique résident dans le fait qu'une fois ouverts, l'élasticité du plastique permet un rappel d'air a l'intérieur du tube ce qui, après chaque expulsion d'une dose de produit, présente des problèmes d'oxydation ou de contamination du contenu. Les tubes en aluminium ne présentent pas cet inconvénient mais leur déformabilité les rend inesthétiques et peu pratiques après quelques utilisations.The present invention relates to a device for the packaging and distribution of pasty or liquid products in the form of a gel or emulsion such as, for example, cosmetic or pharmaceutical products. Generally to package such products, tubes or jars are used. The drawbacks linked to the use of plastic tubes reside in the fact that once opened, the elasticity of the plastic allows air to be drawn back inside the tube which, after each expulsion of a dose of product , presents problems of oxidation or contamination of the contents. Aluminum tubes do not have this drawback, but their deformability makes them unsightly and impractical after a few uses.

Les pots de crème largement utilisés présentent l'inconvénient d' une grande surface de contact entre le contenu et l'environnement d'où des risques importants d'oxydation et de contamination.Widely used cream jars have the disadvantage of a large contact surface between the content and the environment, resulting in significant risks of oxidation and contamination.

The secondary chamber 7 has a shoulder 10 and communicates by a passage expulsion 11, also provided with a non-return valve 12, with the expulsion orifice 2. Each non-return valve 9 or 12 is for example composed of a hollow cylindrical body provided with orifices at each of its ends . The upstream part of this body is frustoconical while the other end of this body has a rim. A ball 13, 13 ′ whose diameter is greater than the diameter of the upstream orifice is placed in this body. A spring 14,14 'tends to apply the ball 13,13' against the internal face of the tronconi part that of the body. The non-return valves 9, 12 are placed so as to allow the product to pass between the primary chamber 3 and the secondary chamber 7 and from the latter to the expulsion channel 2.

Un ressort 15 est disposé dans la chambre secondaire 7 et vient prendre appui d'une part contre l'épaulement 10 de ladite chambre et d'autre part contre un organe de commande formé d'un piston 16 solidaire d'un bouton poussoir 17 accessible depuis l'extérieur du boîtier 1. Lorsque l'on actionne le bouton poussoir 17 dans le sens de la flèche A, le piston 16 coulissant sans jeu dans la chambre secondaire comprime la dose de produit contenue dans cette chambre secondaire 7 ce qui déplace la bille 13' contre l'action de son ressort 14' et permet l'expulsion d'une quantité de produit par l'orifice d'expulsion 2. Le clapet de non retour 9 empêche pendant cette opération le produit contenu dans la chambre secondaire 7 de refluer dans la chambre primaire 3. Lorsque le bouton poussoir 17 revient dans sa position initiale sous l'action du ressort 15, une dépression est créée dans la chambre secondaire 7 ce qui a pour effet d'obturer le clapet de non retour 12 et de provoquer un appel de produit de la chambre primaire vers la chambre secondaire à travers le clapet de non retour 9. Le piston primaire se déplace dans le sens de la flèche B sous l'action de la pression atmosphérique et éventuellement d'un ressort d'appoint (non illustré) ajustant le volume de la partie de la chambre primaire contenant le produit au volume restant de celui-ci.A spring 15 is disposed in the secondary chamber 7 and bears on the one hand against the shoulder 10 of said chamber and on the other hand against a control member formed by a piston 16 secured to a push button 17 accessible from outside the housing 1. When the push button 17 is actuated in the direction of arrow A, the piston 16 sliding without play in the secondary chamber compresses the dose of product contained in this secondary chamber 7 which displaces the ball 13 'against the action of its spring 14' and allows the expulsion of a quantity of product through the expulsion orifice 2. The non-return valve 9 prevents during this operation the product contained in the secondary chamber 7 to flow back into the primary chamber 3. When the push button 17 returns to its initial position under the action of the spring 15, a vacuum is created in the secondary chamber 7 which has the effect of closing the non-return valve 12 and to trigger an app el of product from the primary chamber to the secondary chamber through the non-return valve 9. The primary piston moves in the direction of arrow B under the action of atmospheric pressure and possibly a booster spring ( not illustrated) adjusting the volume of the part of the primary chamber containing the product to the remaining volume thereof.

Il est à noter que seule la très faible quantité de produit restant dans le clapet de non retour 12 est en contact avec l'air extérieur et donc soumise à une éventuelle oxydation ou contamination.It should be noted that only the very small amount of product remaining in the non-return valve 12 is in contact with the outside air and therefore subject to possible oxidation or contamination.

Dans la deuxième variante illustrée aux figures 4 et 5 la chambre secondaire 7 est reliée directement au canal d'expulsion 2 sans clapet de non retour. Une fente 19 située parallèlement à l'axe du piston 16 est ménagée dans le boîtier 1. Le piston 16 est solidaire d'une languette 20 percée d'une fente 21. Lorsque le bouton poussoir 17 est en position enfoncée comme illustré à la figure 4, la fente 21 de la languette 20 vient coïncider avec le canal d'expulsion 2 permettant ainsi à la dose de produit contenue dans la chambre secondaire 7 d'être expulsée. Lorsque le bouton poussoir 17 revient dans sa position de repos sous l'action du ressort 15, la languette 20 vient obturer le canal d'expulsion 2. Dans cette forme d'exécution, l'orifice d'expulsion étant obturé en position inactive de l'emballage il n'y a pas de contact entre le produit et l'air extérieur, assurant de ce fait une protection totale du produit contre l'oxydation ou la contamination.In the second variant illustrated in Figures 4 and 5 the secondary chamber 7 is directly connected to the expulsion channel 2 without non-return valve. A slot 19 located parallel to the axis of the piston 16 is formed in the housing 1. The piston 16 is integral with a tongue 20 pierced with a slot 21. When the push button 17 is in the depressed position as illustrated in the figure 4, the slot 21 of the tongue 20 coincides with the expulsion channel 2 thus allowing the dose of product contained in the secondary chamber 7 to be expelled. When the push button 17 returns to its rest position under the action of the spring 15, the tongue 20 closes the expulsion channel 2. In this embodiment, the expulsion orifice being closed in the inactive position of the packaging there is no contact between the product and the outside air, thus ensuring total protection of the product against oxidation or contamination.

La figure 6 représente une troisième variante de l'emballage et comporte une chambre unique 22 séparée en deux parties par un piston libre 23. Une des parties est remplie du produit à distribuer tandis que l'autre est mise à l'air par un perçage pratiqué dans le fond du boîtier. Un ressort 24 prenant appui d'une part contre le fond du boîtier et d'autre part contre le piston libre 23 permet de mettre le produit sous pression. Le boîtier comporte un tube 25 ou des colonnettes de guidage situé dans l'axe de l'orifice d'expulsion, solidaire de la paroi arrière du boîtier, l'autre extrémité de ce tube étant située à une distance de l'orifice d'expulsion déterminée par la taille de l'organe d'obturation décrit ci-dessous. Une bille 26 dont le diamètre est sensiblement supérieur au diamètre de l'orifice d'expulsion est placée dans ce tube 25. Un ressort 27 dans le tube 25 tend à appliquer la bille 26 contre l'orifice d'expulsion. Lorsque l'on exerce une pression avec le doigt sur la partie de la bille 26 qui émerge de l'orifice d'expulsion, le produit étant sous pression sort par l'orifice d'expulsion jusqu'à ce que l'on relâche la pression sur la bille 26 qui vient alors à nouveau obturer l'orifice d'expulsion sous l'action du ressort 27.FIG. 6 represents a third variant of the packaging and comprises a single chamber 22 separated into two parts by a free piston 23. One of the parts is filled with the product to be dispensed while the other is vented by a bore practiced in the bottom of the case. A spring 24 bearing on the one hand against the bottom of the housing and on the other hand against the free piston 23 makes it possible to put the product under pressure. The housing comprises a tube 25 or guide posts located in the axis of the expulsion orifice, integral with the rear wall of the housing, the other end of this tube being located at a distance from the orifice. expulsion determined by the size of the obturation member described below. A ball 26 whose diameter is substantially greater than the diameter of the expulsion orifice is placed in this tube 25. A spring 27 in the tube 25 tends to apply the ball 26 against the expulsion orifice. When pressure is exerted with the finger on the part of the ball 26 which emerges from the expulsion orifice, the product being under pressure exits through the expulsion orifice until the pressure is released. pressure on the ball 26 which then again closes the expulsion orifice under the action of the spring 27.

L'utilisateur peut ainsi déterminer la quantité de produit désirée. La bille 27 peut être remplacée par un corps 28 cylindrique tel qu'illustré aux figures 8 et 9. La tête de ce corps 28 comporte une découpe en biseau 29. La découpe 29 émerge du boîtier sous l'action du ressort 27. Lorsque l'on exerce une pression sur ce corps (fig 9), la tête du corps 28 s'enfonce dans le boîtier, la découpe 29, permettant au produit d'être expulsé. Cette solution a l'avantage que la sortie du produit ne s'effectue que par la découpe 29, c'est-à-dire suivant une direction privilégiée rendant l'utilisation de l'emballage plus aisée.The user can thus determine the quantity of product desired. The ball 27 can be replaced by a cylindrical body 28 as illustrated in FIGS. 8 and 9. The head of this body 28 has a bevel cut 29. The cut 29 emerges from the housing under the action of the spring 27. When the 'pressure is exerted on this body (fig 9), the head of the body 28 sinks into the housing, the cutout 29, allowing the product to be expelled. This solution has the advantage that the output of the product is only carried out by cutting 29, that is to say in a preferred direction making use of the packaging easier.

La figure 10 montre une quatrième variante de l'emballage selon la première forme d'exécution de l'invention dans laquelle deux produits différents sont présents dans le boîtier et se mélangent au moment de l'expulsion. Dans cette forme d'exécution, le boîtier 1 comporte une chambre primaire séparée longitudinalement en deux demi-chambres 30,30' par une cloison étanche 31, chacune de ces demi-chambres 30,30' comporte un piston primaire libre 32,32' muni d'un joint d'étanchéité 33,33'. Un ressort 34,34' est introduit entre le fond du boîtier et le piston primaire 32,32' de chacune des deux demi-chambres 30,30' de sorte que les produits contenus dans chacune des parties supérieures desdites demi-chambres 30,30' soient sous pression. La demi-chambre de droite 30 communique par un canal d'aspiration, dans lequel se situe un clapet de non retour 35, avec la chambre secondaire 7 contenant le piston de commande 16 solidaire du bouton poussoir 17 comme dans la première forme d'exécution décrite ci dessus. La demicham- bre de gauche 30' communique par un canal d'aspiration muni d'un clapet de non retour 35' avec une deuxième chambre secondaire 36. Cette chambre secondaire 36 comporte un piston 37. Ce piston 37 est solidaire du piston de commande 16 coulissant librement dans la chambre secondaire 7 par l'intermédiaire d'un axe 38 coulissant de façon étanche dans un passage 39 ménagé dans le boîtier 1 entre les chambres secondaires 7 et 36. Un canal d'expulsion 40 relie la deuxième chambre secondaire 36 a un second orifice d'expulsion 41 situé à proximité du premier orifice d'expulsion 2 dans la creusure du boîtier 1. Lorsque l'on actionne le bouton poussoir 17 dans le sens de la flèche A, le piston 16 entraînant le piston 37, comprime les doses de produits contenues dans les chambres secondaires 7,36 et les doses de produits sont expulsées respectivement par les orifices 2 et 41. Les clapets de non retour 35,35' empêchent les produits de refluer vers les demi-chambres primaires 30,30'. Lorsque les pistons 16,37 reviennent en position de service sous l'action des ressorts, une dépression est crée dans les chambres secondaires 7,36 ce qui provoque un appel de produit des demichambres 30,30' vers les chambres secondaires 7,36 à travers les clapets de non-retour 35,35'. Les pistons primaires 32,32' se déplacent dans le sens des flèches B B' sous l'action des ressorts 34,34'. Cette forme d'exécution de l'emballage, permet d'expulser une dose composée de deux produits différents qui ne se mélangent qu'au moment de l'utilisation. Dans cette forme d'exécution, le piston 16 peut coopérer avec un organe d'obturation des deux orifices d'expulsion 2,41 comme celui décrit dans la deuxième forme d'exécution aux figures 4 et 5.Figure 10 shows a fourth variant of the packaging according to the first embodiment of the invention in which two different products are present in the housing and mix at the time of expulsion. In this embodiment, the housing 1 comprises a primary chamber separated longitudinally into two half-chambers 30.30 'by a watertight partition 31, each of these half-chambers 30.30' comprises a free primary piston 32.32 ' fitted with a 33.33 'gasket. A spring 34.34 'is introduced between the bottom of the housing and the primary piston 32.32' of each of the two half-chambers 30.30 'so that the products contained in each of the upper parts of said half-chambers 30.30 'are under pressure. The right-hand half-chamber 30 communicates by a suction channel, in which there is a non-return valve 35, with the secondary chamber 7 containing the control piston 16 secured to the push button 17 as in the first embodiment described above. La demicham- left bre 30 'communicates by a suction channel provided with a non-return valve 35' with a second secondary chamber 36. This secondary chamber 36 comprises a piston 37. This piston 37 is integral with the control piston 16 sliding freely in the secondary chamber 7 by means of an axis 38 sealingly sliding in a passage 39 formed in the housing 1 between the secondary chambers 7 and 36. An expulsion channel 40 connects the second secondary chamber 36 to a second expulsion orifice 41 located near the first expulsion orifice 2 in the recess of the housing 1. When the push button 17 is actuated in the direction of arrow A, the piston 16 driving the piston 37, compresses the doses of products contained in the secondary chambers 7,36 and the doses of products are expelled respectively through the orifices 2 and 41. The non-return valves 35,35 'prevent the products from flowing back to the primary half-chambers 30,30'. When the pistons 16,37 return to the service position under the action of the springs, a vacuum is created in the secondary chambers 7,36 which causes a product call from the half-chambers 30,30 'to the secondary chambers 7,36 to through the non-return valves 35.35 '. The primary pistons 32,32 'move in the direction of the arrows BB' under the action of the springs 34,34 '. This embodiment of the packaging makes it possible to expel a dose composed of two different products which do not mix until use. In this embodiment, the piston 16 can cooperate with a shutter member for the two expulsion orifices 2.41 like that described in the second embodiment in FIGS. 4 and 5.

En variant le diamètre des chambres secondaires 7,36 l'un par rapport à l'autre on modifie la proportion des produits expulsés simultanément.By varying the diameter of the secondary chambers 7.36 relative to one another, the proportion of the products expelled simultaneously is modified.

L'emballage ou dispositif de conditionnement et de distribution selon l'invention peut être à usage unique ou rechargeable, dans ce cas le fond du boîtier est amovible et l'on peut introduire une recharge sous forme d'une cartouche ayant par exemple un fond rigide dont la forme correspond au boîtier et un sac souple contenant le produit. Le fond de la recharge fait office de piston primaire.The packaging or packaging and dispensing device according to the invention can be for single use or refillable, in this case the bottom of the case is removable and a refill can be introduced in the form of a cartridge having for example a bottom rigid whose shape corresponds to the case and a flexible bag containing the product. The bottom of the refill acts as the primary piston.

D'une façon générale la chambre primaire est séparée en deux parties par un organe de séparation, l'une de ces parties étant reliée à la chambre secondaire et l'autre à l'air libre. L'organe de séparation peut être un piston libre comme décrit plus haut ou une membrane ou une partie souple ou rigide d'une recharge de produit.Generally, the primary chamber is separated into two parts by a separation member, one of these parts being connected to the secondary chamber and the other to the open air. The separation member can be a free piston as described above or a membrane or a flexible or rigid part of a product refill.

L'emballage décrit présente les avantages suivants. Le produit n'est jamais en contact avec l'air extérieur empêchant ainsi toute oxydation. Le contact avec les doigts lorsque l'on se sert du produit est limité à la dose que l'on va utiliser empêchant ainsi toute contamination du reste du produit. L'emballage ne se déforme pas et jouit de qualités esthétiques largement supérieures à celles des tubes déformables. L'utilisation de l'emballage est extrêmement simple et peut être utilisé d'une seule main ce qui n'est pas le cas des tubes. Le produit peut être utilisé dans sa totalité ce qui n'est pas aisé lorsque l'on a à faire à des tubes en plastique. La forme extérieure ainsi que les matériaux utilisés pour la fabrication de l'emballage sont adaptables aux contraintes de stockage de transport et de compatibilité avec le produit. Enfin, il est possible de distribuer simultanément des doses de produits différents, dans une proportion déterminée par l'actionnement d'un seul poussoir.The packaging described has the following advantages. The product is never in contact with the outside air thus preventing any oxidation. Contact with fingers when using the product is limited to the dose that will be used, thus preventing contamination of the rest of the product. The packaging does not deform and enjoys aesthetic qualities far superior to those of deformable tubes. The use of the packaging is extremely simple and can be used with one hand which is not the case for tubes. The product can be used in its entirety which is not easy when dealing with plastic tubes. The external shape as well as the materials used for the manufacture of the packaging are adaptable to the storage constraints of transport and compatibility with the product. Finally, it is possible to simultaneously distribute doses of different products, in a proportion determined by the actuation of a single pusher.

Il faut encore noter qu'avec cet emballage on peut faire l'économie d'un emballage secondaire. En effet, l'emballage selon l'invention peut être distribué et vendu sans conditionnement, emballage ou boite supplémentaire, ce qui est avantageux.It should also be noted that with this packaging we can save on secondary packaging. In fact, the packaging according to the invention can be distributed and sold without packaging, packaging or additional box, which is advantageous.

La seconde forme d'exécution du dispositif de conditionnement et de distribution d'un produit pâteux ou liquide illustré partiellement en coupe à la figure 11 comporte un boîtier rigide 50 présentant une chambre 51 destinée à recevoir le produit à distribuer reliée par un canal 52 et un premier clapet de non-retour 53 au fond d'un alésage 54 recevant le mécanisme de distribution du produit.The second embodiment of the device for packaging and distributing a pasty or liquid product illustrated partially in section in FIG. 11 comprises a rigid housing 50 having a chamber 51 intended to receive the product to be distributed connected by a channel 52 and a first non-return valve 53 at the bottom of a bore 54 receiving the product distribution mechanism.

Ce mécanisme de distribution du produit est constitué par un orifice de sortie 55 débouchant dans l'alésage 54 d'un piston principal 56 coulissant dans l'alésage 54 contre l'action d'un ressort de rappel 57.This product distribution mechanism consists of an outlet orifice 55 opening into the bore 54 of a main piston 56 sliding in the bore 54 against the action of a return spring 57.

Le piston principal 56 comporte une chambre 58 débouchant sur sa face frontale et obturée par un second clapet de non-retour 59. Ce second clapet de non-retour 59 est pincé en sandwich entre la face frontale du piston principal 56 et une rondelle 59a dont le trou est d'une dimension correspondant au passage de la soupape 59. La rondelle 59a et la soupape 59 sont appliquées contre la face du piston 56 par le ressort 57. Cette chambre 58 est reliée par un canal 60 à une chambre annulaire 61 débouchant sur la périphérie du piston principal. Des joints sont prévus entre le piston principal 56 et le boîtier 50 à proximité de l'extrémité frontale du piston et de chaque côté de la chambre annulaire 61. Ces joints peuvent être venus d'une pièce de moulage avec le piston 56.The main piston 56 has a chamber 58 opening on its front face and closed by a second non-return valve 59. This second non-return valve 59 is sandwiched between the front face of the main piston 56 and a washer 59a of which the hole is of a dimension corresponding to the passage of the valve 59. The washer 59a and the valve 59 are applied against the face of the piston 56 by the spring 57. This chamber 58 is connected by a channel 60 to an annular chamber 61 opening out on the periphery of the main piston. Seals are provided between the main piston 56 and the housing 50 near the front end of the piston and on each side of the annular chamber 61. These seals may have come from a molding piece with the piston 56.

Le piston principal 56 comporte encore un alésage central borgne 62, présentant un épaulement, débouchant dans la chambre 58. Un piston 63 de décompression coulisse dans cet alésage central librement sous l'action d'un ressort de rappel 64.The main piston 56 also has a blind central bore 62, having a shoulder, opening into the chamber 58. A decompression piston 63 slides in this central bore freely under the action of a return spring 64.

Dans cette forme d'exécution le piston principal est solidaire d'un poussoir 65 pour son actionnement. Il est évident que n'importe quel organe ou dispositif d'actionnement, à gâchette, à crémaillère, etc. pourrait être prévu pour déplacer le piston principal contre l'action du ressort 57 dans l'alésage 54.In this embodiment, the main piston is integral with a pusher 65 for its actuation. Obviously any organ or actuator, trigger, rack, etc. could be provided to move the main piston against the action of the spring 57 in the bore 54.

La chambre 51 contenant le produit à conditionner et à distribuer est obturée vers le fond du boîtier 50 par un fond mobile 66 muni de lèvres d'étanchéité frottant contre le boîtier 50 et coulissant librement dans ladite chambre 51.The chamber 51 containing the product to be packaged and dispensed is closed towards the bottom of the case 50 by a movable bottom 66 provided with sealing lips rubbing against the case 50 and sliding freely in said chamber 51.

Le fonctionnement du dispositif doseur ou de distribution décrit est le suivant :

  • A l'état de repos, le dispositif est dans la position illustrée à la figure 11. Le canal 52, la chambre 58, le canal 60 et la chambre annulaire 61 sont plein de produit à distribuer. L'orifice de sortie 55 est obturé par le piston principal 56.
The operation of the metering or distribution device described is as follows:
  • In the rest state, the device is in the position illustrated in FIG. 11. The channel 52, the chamber 58, the channel 60 and the annular chamber 61 are full of product to be dispensed. The outlet orifice 55 is closed by the main piston 56.

A partir de cet état l'utilisateur pousse le poussoir 65 suivant la flèche F déplaçant le piston principal 56 à l'intérieur de l'alésage 54 contre l'action du ressort 57 ce qui provoque :

  • - dans un premier temps (fig. 12) la fermeture du clapet de non-retour 53 et l'ouverture du clapet de non-retour 59 autorisant l'introduction du produit contenu dans le fond de l'alésage 54 dans la chambre 58 du piston principal 56 provoquant le déplacement du piston de décompression 63 contre l'action de son ressort de rappel 64. Ainsi, bien que l'orifice de sortie 55 soit fermé, le produit à distribuer n'est pas mis sous pression par le déplacement du piston principal 56;
  • - dans un second temps (fig. 13), dès que la chambre annulaire 60 du piston principal 56 est en communication avec l'orifice de sortie, tout déplacement subséquent du piston principal 56 provoque l'expulsion d'une dose de produit, dose dont le volume est défini par la course et le diamètre de ce piston principal. La fin de la distribution du produit intervient soit quand le piston principal arrive en fin de course, soit quand la chambre annulaire 61 de ce piston n'est plus en communication avec l'orifice de sortie. Entre-temps, le piston secondaire est revenu en position de repos sous l'action de son ressort de rappel.
From this state the user pushes the pusher 65 along the arrow F moving the main piston 56 inside the bore 54 against the action of the spring 57 which causes:
  • - firstly (fig. 12) closing the non-return valve 53 and opening the non-return valve 59 authorizing the introduction of the product contained in the bottom of the bore 54 into the chamber 58 of the main piston 56 causing the displacement of the decompression piston 63 against the action of its return spring 64. Thus, although the outlet orifice 55 is closed, the product to be dispensed is not pressurized by the displacement of the main piston 56;
  • - in a second step (fig. 13), as soon as the annular chamber 60 of the main piston 56 is in communication with the outlet orifice, any subsequent movement of the main piston 56 causes the expulsion of a dose of product, dose whose volume is defined by the stroke and the diameter of this main piston. The end of the product distribution occurs either when the main piston reaches the end of the stroke, or when the annular chamber 61 of this piston is no longer in communication with the outlet orifice. Meanwhile, the secondary piston has returned to the rest position under the action of its return spring.

Lorsque l'utilisateur relâche le poussoir 65, le piston principal 56 retourne en position de repos (fig. 11) sous l'action du ressort 57. Ce faisant, le clapet de non-retour 59 se ferme interdisant tout appel d'air par l'orifice de sortie 55 tandis que le clapet de non-retour 53 s ouvre et que du produit de la chambre 51 est aspiré par vacuum au travers du canal 52 dans l'extrémité de l'alésage 54. En fin de course de retour du piston principal 56, l'orifice de sortie 55 est à nouveau obturé. Le fond mobile 66 remonte dans la chambre 51 sous l'effet du vacuum créé, évitant ainsi tout contact du produit avec l'air.When the user releases the plunger 65, the main piston 56 returns to the rest position (fig. 11) under the action of the spring 57. In doing so, the non-return valve 59 closes preventing any call for air by the outlet 55 while the non-return valve 53 opens and the product from the chamber 51 is vacuum drawn through the channel 52 into the end of the bore 54. End of return stroke of the main piston 56, the outlet orifice 55 is again closed. The movable bottom 66 rises in the chamber 51 under the effect of the vacuum created, thus avoiding any contact of the product with the air.

De plus, ce mécanisme est très simple, nécessite peu de pièces et est facile à fabriquer, les pièces pouvant soit être facilement usinées, injectées ou moulées.In addition, this mechanism is very simple, requires few parts and is easy to manufacture, the parts can either be easily machined, injected or molded.

Dans la troisième forme d'exécution du dispositif illustré à la figure 14, le boîtier 50 comporte deux chambres 51, 51 a, destinées à recevoir deux produits différents, l'un pâteux et l'autre liquide par exemple. Le mécanisme de distribution et de dosage du produit contenu dans la chambre 51 du boîtier est identique à celui décrit en relation avec les figures 11 à 13. Le mécanisme de distribution et de dosage du produit contenu dans la chambre 51 a peut comporter un clapet de non-retour 67 situé dans le haut de la chambre 51 a qui comporte un trou 68 débouchant dans l'alésage 54. Dans une variante, cette soupape ou clapet de non-retour 67 peut être supprimée. Le piston principal 56 comporte une seconde chambre annulaire 69, également délimitée par des joints, et le boîtier comporte un second orifice de sortie 70. Enfin, chacune des chambres 51, 51 a, comporte un fond mobile 66, 66a.In the third embodiment of the device illustrated in Figure 14, the housing 50 has two chambers 51, 51a, intended to receive two different products, one pasty and the other liquid for example. The mechanism for dispensing and metering the product contained in the chamber 51 of the housing is identical to that described in relation to FIGS. 11 to 13. The mechanism for dispensing and metering the product contained in the chamber 51 a may include a check valve. non-return 67 located in the top of the chamber 51 a which has a hole 68 opening into the bore 54. In a variant, this non-return valve or valve 67 can be omitted. The main piston 56 comprises a second annular chamber 69, also delimited by seals, and the housing comprises a second outlet orifice 70. Finally, each of the chambers 51, 51 a, has a movable bottom 66, 66a.

Lorsque 1 usager appuie sur le poussoir 65, la distribution du produit contenu dans la chambre 51 s'effectue comme précédemment décrit. Pendant cette course aller du piston principal 56, le clapet de non-retour 67 reste fermé. Par contre, lors de la course de retour du piston principal 56, pendant que la chambre annulaire 69 est en communication avec le trou 68, le produit contenu dans la chambre 51 a, poussé par le fond 66a relié rigidement au fond 66 de la chambre 51, ouvre le clapet de non-retour 67, pénètre dans la chambre annulaire 69 et est expulsé par l'orifice de sortie 70. Dès que la chambre annulaire 69 n'est plus en liaison avec l'orifice de sortie 70 et le trou 68, l'expulsion du second produit est stoppée. Ainsi, pour l'expulsion du produit contenu dans la chambre 51 a, on utilise le déplacement du fond 66 de la chambre 51, s'effectuant par vacuum pour provoquer un déplacement correspondant du fond 66a de la chambre 51 a. De cette façon, on s'assure que les deux chambres 51 et 51 a sont vides simultanément.When 1 user presses the pusher 65, the product contained in the chamber 51 is dispensed as previously described. During this forward stroke of the main piston 56, the non-return valve 67 remains closed. On the other hand, during the return stroke of the main piston 56, while the annular chamber 69 is in communication with the hole 68, the product contained in the chamber 51 has, pushed by the bottom 66a rigidly connected to the bottom 66 of the chamber 51, opens the non-return valve 67, enters the annular chamber 69 and is expelled through the outlet orifice 70. As soon as the annular chamber 69 is no longer in connection with the outlet orifice 70 and the hole 68, the expulsion of the second product is stopped. Thus, for the expulsion of the product contained in the chamber 51 a, the displacement of the bottom 66 of the chamber 51 is used, taking place by vacuum to cause a corresponding displacement of the bottom 66a of the chamber 51 a. In this way, it is ensured that the two chambers 51 and 51 a are empty simultaneously.

Dans la quatrième forme d'exécution illustrée à la figure 15, le dispositif est similaire à celui décrit en référence à la figure 14, mais la seconde chambre 51 a est entièrement entourée par la chambre 51 qui présente une forme cylindrique creuse. Le fond mobile 66 de la chambre 51 est également de forme annulaire. Une jupe-piston 71 ou fond du boîtier 50 est prévu qui coulisse librement à l'intérieur des parois externes du boîtier 50 et qui est solidaire des fonds mobiles 66 et 66a. Cette jupe-piston 71 comporte une rainure annulaire 72 destinée à donner passage à la paroi annulaire 73 de la seconde chambre 51 a lors de ses déplacements vers le haut. De cette façon, le déplacement du fond mobile 66a est provoqué par le déplacement de la jupe-piston 71 entraînée dans les déplacements du fond mobile 66.In the fourth embodiment illustrated in Figure 15, the device is similar to that described with reference to Figure 14, but the second chamber 51a is entirely surrounded by the chamber 51 which has a hollow cylindrical shape. The movable bottom 66 of the chamber 51 is also of annular shape. A piston skirt 71 or bottom of the housing 50 is provided which slides freely inside the external walls of the housing 50 and which is integral with the movable bottoms 66 and 66a. This piston skirt 71 has an annular groove 72 intended to give passage to the annular wall 73 of the second chamber 51 a during its upward movements. In this way, moving the movable bottom 66a is caused by the displacement of the piston skirt 71 entrained in the displacements of the movable bottom 66.

Dans cette dernière forme d'exécution, le clapet de non-retour 67 est supprimé, l'étanchéité de la seconde chambre 51 a étant assurée par le jeu du piston principal et des orifices 68 et 70.In this latter embodiment, the non-return valve 67 is eliminated, the sealing of the second chamber 51 a being ensured by the play of the main piston and the orifices 68 and 70.

Dans les trois dernières formes d'exécution décrites, les clapets de non-retour sont constitués par des disques ou rondelles en matière plastique moulée présentant une languette centrale reliée par une portion de son pourtour au disque. Ce disque présente un trou de dimensions légèrement inférieures à celles de la languette mobile par flexion. La languette est déplaçable par rapport au disque pour soit obturer le trou de celui-ci, soit au contraire pour libérer un passage au travers du disque. Pour faciliter la déformation élastique de la languette de façon préférentielle dans un sens, le disque présente un affaiblissement sur l'une de ses faces à l'endroit où la languette lui est raccordée.In the last three embodiments described, the non-return valves consist of discs or washers of molded plastic material having a central tongue connected by a portion of its periphery to the disc. This disc has a hole of dimensions slightly smaller than those of the movable tongue by bending. The tongue is movable relative to the disc to either close the hole thereof, or on the contrary to free a passage through the disc. To facilitate the elastic deformation of the tongue preferably in one direction, the disc has a weakening on one of its faces at the place where the tongue is connected to it.

Ce clapet de non-retour est très simple, bon marché, facile à fabriquer et s'est avéré très fiable.This check valve is very simple, inexpensive, easy to manufacture and has proven to be very reliable.

Le clapet 53 présente un disque d'un diamètre extérieur correspondant au diamètre intérieur de l'alésage borgne 54 et est maintenu contre le fond de celui-ci par l'appui du ressort 57.The valve 53 has a disc with an outside diameter corresponding to the inside diameter of the blind bore 54 and is held against the bottom of the latter by the support of the spring 57.

Le clapet 59 présente un diamètre externe correspondant au diamètre extérieur du piston principal 56 et est appliqué contre l'extrémité frontale de celui-ci par une rondelle soumise à l'action du ressort 57.The valve 59 has an external diameter corresponding to the external diameter of the main piston 56 and is applied against the front end of the latter by a washer subjected to the action of the spring 57.

Enfin, le clapet 67 est maintenu entre une cloison perforée dans la partie supérieure de la seconde chambre 51 a et un bossage annulaire ou rondelle situé entre cette paroi supérieure percée et la paroi de l'alésage borgne du boîtier.Finally, the valve 67 is held between a perforated partition in the upper part of the second chamber 51 a and an annular boss or washer situated between this pierced upper wall and the wall of the blind bore of the housing.

Dans des variantes du dispositif, les chambres 51 et/ou 51 a pourraient contenir ou être remplacées par des poches remplies contenant le produit à distribuer. Ces poches pourraient être reliées de façon amovible aux orifices de sortie du produit dans l'alésage 54 de manière à pouvoir être jetées lorsqu'elles sont vides et remplacées par des poches pleines.In variants of the device, the chambers 51 and / or 51 a could contain or be replaced by filled pockets containing the product to be dispensed. These pockets could be removably connected to the product outlet orifices in the bore 54 so that they can be discarded when they are empty and replaced by full pockets.

Ces trois dernières formes d'exécution du dispositif selon l'invention résolvent les mêmes problèmes et présentent les mêmes avantages que ceux énumérés en se référant à la première forme d'exécution.These last three embodiments of the device according to the invention solve the same problems and have the same advantages as those listed with reference to the first embodiment.
