An Independent claim is included for a method of manufacturing the container/dispenser.

Description

La présente invention a pour objet un dispositif de conditionnement et de distribution d'au moins un produit fluide.The present invention relates to a device for packaging and distribution of at least one fluid product.

On connaít des dispositifs de conditionnement et de distribution d'un produit fluide, comportant un réservoir pour contenir ledit produit et une pompe associée, comprenant une chambre de pompage dans laquelle le produit est aspiré avant d'être refoulé à l'extérieur.We know packaging devices and distribution of a fluid product, comprising a reservoir for contain said product and an associated pump, comprising a chamber pumping system in which the product is sucked before being discharged to outside.

La pompe comporte des moyens formant clapet d'aspiration et des moyens formant clapet de refoulement, respectivement en amont et en aval de la chambre de pompage. La pression nécessaire à l'expulsion du produit hors du dispositif est obtenue au moyen d'une tige de Commande mobile dans la chambre de pompage. Un embout de distribution tel qu'un bouton-poussoir équipé d'une buse est fixé sur la tige de commande avant le remplissage du réservoir.The pump comprises means forming a suction valve and means forming a discharge valve, respectively upstream and in downstream of the pumping chamber. The pressure necessary to expel the product outside the device is obtained by means of a control rod mobile in the pumping chamber. A dispensing tip such as a push button fitted with a nozzle is fixed on the control rod before filling the tank.

Lorsque l'utilisateur appuie sur l'embout de distribution, la tige de commande s'enfonce dans le corps de la pompe et diminue le volume de la chambre de pompage, provoquant la distribution d'une quantité prédéterminée de produit.When the user presses the dispensing tip, the control rod sinks into the pump body and decreases the volume of the pumping chamber, causing the distribution of a predetermined amount of product.

Lorsque l'utilisateur relâche l'embout de distribution, la tige de commande est rappelée dans sa position initiale par un ressort. Ce mouvement de retour de la tige de commande s'accompagne d'une augmentation de volume de la chambre de pompage. Les moyens formant clapet de refoulement sont agencés pour empêcher le retour du produit contenu dans l'embout de distribution vers la chambre de pompage ainsi qu'une rentrée d'air. Les moyens formant clapet d'aspiration s'ouvrent durant la phase de remontée de la tige de commande pour permettre au produit contenu dans le réservoir d'être aspiré dans la chambre de pompage.When the user releases the dispensing tip, the rod is returned to its initial position by a spring. This return movement of the control rod is accompanied by a increase in volume of the pumping chamber. The means forming discharge valve are arranged to prevent the return of the product contained in the dispensing nozzle to the pumping chamber as well than an air intake. The means forming a suction valve open during the ascent phase of the control rod to allow the product contained in the tank to be sucked into the chamber pumping.

Le réservoir peut être constitué par une poche souple déformable qui se rétracte au fur et à mesure que le produit est distribué ou, en variante, être formé par une paroi cylindrique muni d'un fond mobile constitué par exemple par un piston pouvant coulisser à l'intérieur de celle-ci ou en variante par une membrane qui se déforme pour occuper à l'intérieur du réservoir l'espace laissé par le produit qui a été distribué.The tank can consist of a flexible pocket deformable which shrinks as the product is distributed or, alternatively, be formed by a cylindrical wall provided a movable bottom constituted for example by a piston which can slide inside it or alternatively by a membrane which deforms to occupy inside the tank the space left by the product that has been distributed.

Dans les dispositifs de conditionnement et de distribution connus tels que rappelés ci-dessus, le remplissage du réservoir peut s'effectuer par un processus de remplissage sous vide consistant à créer une dépression dans le réservoir puis à mettre ce réservoir en communication avec la source de produit afin que ce dernier se trouve aspiré.In packaging and distribution systems known as recalled above, the filling of the tank can be carried out by a vacuum filling process consisting of create a depression in the tank then put this tank in communication with the product source so that the product is located sucked.

Un tel processus de remplissage présente notamment les avantages de permettre une cadence de production élevée et d'éviter l'oxydation du produit au contact de l'air.Such a filling process presents in particular the advantages of enabling a high production rate and avoiding oxidation of the product on contact with air.

Le montage de l'embout de distribution sur la tige de commande s'effectue en engageant à force la tige de commande dans un logement adapté de l'embout de distribution, et s'accompagne d'un enfoncement de la tige de commande dans le corps de la pompe jusqu'à ce que la tige de commande vienne en butée de fin de course d'enfoncement.The mounting of the dispensing nozzle on the control rod is carried out by forcibly engaging the control rod in a housing adapted from the dispensing nozzle, and is accompanied by a depression of the control rod in the pump body until the control rod comes to the end of the driving stroke.

Des essais ont montré qu'en cas de montage de l'embout de distribution sur la tige de commande après le remplissage sous vide du réservoir, l'enfoncement de la tige de commande provoquait l'expulsion d'une certaine quantité de produit, occasionnant des salissures et risquant en outre d'entraíner une dégradation au contact de l'air du produit contenu dans le canal de sortie de l'embout de distribution, voire le colmatage de ce canal de sortie après séchage du produit.Tests have shown that when the tip of the distribution on the control rod after vacuum filling of the tank, pushing in the control rod caused expulsion a certain amount of product, causing soiling and risking further degradation in contact with the air of the product contained in the outlet channel of the dispensing nozzle, or even the clogging of this outlet channel after drying of the product.

Il existe par ailleurs un besoin pour disposer de dispositifs de conditionnement et de distribution comportant deux réservoirs indépendants et deux pompes pour distribuer simultanément les deux produits stockés séparément dans chacun des réservoirs.There is also a need to have devices packaging and distribution with two tanks independent and two pumps to distribute both simultaneously products stored separately in each tank.

Le montage d'un embout de distribution commun sur les tiges de commande des deux pompes après le remplissage sous vide des réservoirs présenterait les inconvénients précités et le montage de l'embout de distribution avant le remplissage des réservoirs complique la fabrication du dispositif.The mounting of a common distribution nozzle on the rods of control of the two pumps after filling the tanks under vacuum would have the aforementioned drawbacks and the mounting of the end piece distribution before filling the tanks complicates the manufacturing of the device.

La présente invention vise notamment à permettre le montage de l'embout de distribution sur la ou les tiges de commande de la ou des pompes après le remplissage sous vide du ou des réservoirs, sans les inconvénients mentionnés plus haut. The present invention aims in particular to allow the mounting of the dispensing nozzle on the control rod (s) of the pumps after vacuum filling of the tank (s), without the disadvantages mentioned above.

Elle y parvient par le fait que le dispositif de conditionnement et de distribution selon l'invention comporte des moyens formant clapet anti-vide, agencés pour isoler la chambre de pompage de la ou des pompes de l'intérieur du ou des réservoirs associés lorsque le vide est créé dans ce ou ces derniers pour le remplissage.It achieves this by the fact that the packaging and distribution according to the invention comprises means forming an anti-vacuum valve, arranged to isolate the chamber from pumping of the pump (s) from inside the tank (s) associated when a vacuum is created in this or these for the filling.

Ainsi, grâce à l'invention, le vide n'est pas créé dans la chambre de pompage lors de l'aspiration de l'air initialement présent dans le réservoir associé de sorte que lorsque ce dernier est mis en communication avec la source de produit, celui-ci remplit seulement le réservoir et non la chambre de pompage.Thus, thanks to the invention, the vacuum is not created in the pumping chamber during the suction of the air initially present in the associated tank so that when the latter is put in communication with the product source, it only fulfills the tank and not the pumping chamber.

Il en résulte que, lorsque l'embout de distribution est ultérieurement fixé sur la ou les tiges de commande et que cette ou ces dernières s'enfoncent dans le corps de la pompe, le produit ne s'écoule pas hors de l'embout de distribution.As a result, when the dispensing tip is subsequently fixed on the control rod (s) and that this or the latter sink into the pump body, the product does not does not flow out of the dispensing nozzle.

Grâce à l'invention, l'embout de distribution reste donc sensiblement exempt de produit pendant le stockage et l'on évite tout risque de salissures, de dégradation ou de séchage du produit.Thanks to the invention, the dispensing tip therefore remains substantially free of product during storage and avoid all risk of soiling, degradation or drying of the product.

En d'autres termes, l'invention permet d'éviter la distribution inopinée d'une dose de produit lors de la mise en place de l'embout de distribution sur la ou les tiges de commande.In other words, the invention makes it possible to avoid the distribution unexpected dose of product when fitting the tip distribution on the control rod (s).

L'invention permet notamment de monter deux pompes équipées chacune d'un réservoir constitué par une poche souple à l'intérieur d'un boítier puis de rapporter sur ce boítier un couvercle servant à la fois à l'actionnement des tiges de commande des pompes et à la distribution du mélange des produits contenus dans les réservoirs.The invention makes it possible in particular to mount two pumps equipped each of a reservoir constituted by a flexible pocket inside of a case then to bring on this case a cover used to both at the actuation of the pump control rods and at the distribution of the mixture of products contained in the tanks.

L'invention présente encore un intérêt lorsque l'embout de distribution est déjà fixé sur une tige de commande avant le remplissage du réservoir.The invention is also of interest when the tip of distribution is already fixed on a control rod before the filling the tank.

En effet, on évite alors, en cas de poussée accidentelle sur l'embout de distribution lors de l'emballage ou durant le transport par exemple, que du produit ne s'écoule hors de l'embout de distribution.In fact, we avoid, in the event of an accidental push on the dispensing nozzle during packaging or during transport for example, that product does not flow out of the nozzle distribution.

Dans les pompes connues, les moyens formant clapet d'aspiration sont constitués par une bille, laquelle n'assure donc l'étanchéité que lorsque la pompe est utilisée dans une position prédéterminée, tête en haut par exemple. In known pumps, the means forming a suction valve consist of a ball, which therefore does not seal that when the pump is used in a predetermined position, head up for example.

Le moyens formant clapet anti-vide selon l'invention sont de préférence capables d'assurer une fermeture étanche dans n'importe quelle position, ce qui accroít les possibilités d'utilisation de la pompe.The means forming an anti-vacuum valve according to the invention are of preferably capable of ensuring a watertight closure in any which position, which increases the possibilities of using the pump.

Dans une réalisation particulière, les moyens formant clapet anti-vide font partie intégrante de la pompe et font également office de clapet d'aspiration, permettant au produit contenu dans le réservoir d'être aspiré dans la chambre de pompage tout en empêchant son retour lorsque la tige de commande est enfoncée.In a particular embodiment, the means forming a valve anti-vacuum are an integral part of the pump and also act as suction valve, allowing the product contained in the tank to be sucked into the pumping chamber while preventing its return when the control rod is pressed.

Dans une variante de réalisation, les moyens formant clapet anti-vide sont rapportés sur la pompe, laquelle est fabriquée à part et peut être constituée par une pompe connue à l'identique ou n'ayant subie que des modifications mineures et peu coûteuses.In an alternative embodiment, the valve means anti-vacuum are reported on the pump, which is manufactured separately and can be constituted by a pump known identically or having no undergone only minor and inexpensive modifications.

Cette pompe est par exemple une pompe du type comportant un clapet constitué par une bille et/ou une tige de commande rappelée par un ressort.This pump is for example a pump of the type comprising a valve constituted by a ball and / or a control rod recalled by a spring.

Dans une autre réalisation, les moyens formant clapet anti-vide comportent une pièce de support assujettie au réservoir et sur laquelle est fixée la pompe.In another embodiment, the means forming an anti-vacuum valve have a support piece attached to the tank and on which is attached to the pump.

Dans une variante encore, les moyens formant clapet anti-vide sont solidaires du réservoir.In yet another variant, the means forming an anti-vacuum valve are integral with the tank.

L'invention a également pour objet un procédé de fabrication d'un dispositif de conditionnement et de distribution d'au moins un produit fluide, ce dispositif comportant au moins un réservoir pour contenir ledit produit et au moins une pompe associée à ce réservoir pour distribuer le produit contenu dans ce dernier, cette pompe présentant une chambre de pompage dans laquelle, lors du fonctionnement de la pompe, le produit est aspiré avant d'être refoulé à l'extérieur, ce procédé étant caractérisé par le fait qu'il comporte les étapes consistant à :

  • assembler la pompe, le réservoir et des moyens formant clapet anti-vide, le réservoir étant apte à communiquer par une première ouverture avec la chambre de pompage au travers des moyens formant clapet anti-vide,
  • faire le vide à l'intérieur du réservoir par une deuxième ouverture de ce dernier, les moyens formant clapet anti-vide isolant la chambre de pompage durant l'étape de mise sous vide du réservoir,
  • remplir le réservoir en le faisant communiquer par ladite deuxième ouverture avec une source de produit,
  • fermer ladite deuxième ouverture.
The invention also relates to a method of manufacturing a device for packaging and distributing at least one fluid product, this device comprising at least one reservoir for containing said product and at least one pump associated with this reservoir for dispensing the product contained in the latter, this pump having a pumping chamber in which, during operation of the pump, the product is sucked before being discharged outside, this process being characterized in that it comprises the stages consisting of:
  • assemble the pump, the reservoir and means forming a vacuum valve, the reservoir being able to communicate by a first opening with the pumping chamber through means forming a vacuum valve,
  • create a vacuum inside the tank by a second opening of the latter, the means forming an anti-vacuum valve isolating the pumping chamber during the vacuuming step of the tank,
  • fill the reservoir by making it communicate through said second opening with a source of product,
  • closing said second opening.

L'invention a encore pour objet un procédé de fabrication d'un dispositif de conditionnement et de distribution comportant deux réservoirs pour contenir séparément chacun un produit et deux pompes respectivement associées à ces réservoirs pour distribuer simultanément lesdits produits, chacune des pompes comportant une chambre de pompage dans laquelle, lors du fonctionnement de la pompe, le produit est aspiré avant d'être refoulé à l'extérieur, ce procédé étant caractérisé par le fait qu'il comporte les étapes consistant à :

  • assembler chaque pompe munie de moyens formant clapet anti-vide avec le réservoir associé,
  • remplir séparément chaque réservoir par un processus de remplissage sous vide,
  • introduire les deux pompes et les réservoirs associés dans un boítier,
  • rapporter sur le boítier un embout de distribution commun aux deux pompes.
The subject of the invention is also a method of manufacturing a packaging and distribution device comprising two reservoirs for each containing a product separately and two pumps respectively associated with these reservoirs for simultaneously distributing said products, each of the pumps comprising a pumping in which, during operation of the pump, the product is sucked before being discharged outside, this process being characterized by the fact that it comprises the steps consisting in:
  • assemble each pump fitted with means forming an anti-vacuum valve with the associated reservoir,
  • fill each tank separately by a vacuum filling process,
  • insert the two pumps and the associated tanks in a box,
  • bring on the housing a distribution nozzle common to the two pumps.

On a représenté sur la figure 1 un dispositif 1 de conditionnement et de distribution selon l'art antérieur.FIG. 1 shows a device 1 for packaging and distribution according to the prior art.

Ce dispositif 1 comporte un réservoir constitué par un récipient 2 à paroi cylindrique, muni d'un fond mobile constitué par un piston 3 coulissant de façon étanche à l'intérieur de la paroi 2.This device 1 comprises a reservoir constituted by a container 2 with cylindrical wall, provided with a movable bottom constituted by a piston 3 sliding tightly inside the wall 2.

Le récipient 2 comporte à sa partie supérieure un col 4 sur lequel est fixée une pompe 5 que l'on a représentée en coupe sur la figure 2.The container 2 has at its upper part a neck 4 on which is attached a pump 5 which is shown in section on the figure 2.

Cette pompe 5 comporte un corps 6 formé par l'assemblage par encliquetage d'une partie supérieure 6a et d'une partie inférieure 6b.This pump 5 comprises a body 6 formed by the snap-fit assembly of an upper part 6 a and a lower part 6 b .

Une tige de commande 8 est montée à coulissement à sa partie inférieure dans le corps 6 contre l'action d'un ressort de rappel 9 travaillant en compression, une extrémité de ce ressort 9 prenant appui contre un épaulement 10 au fond de la partie inférieure 6b du corps 6 et l'autre extrémité prenant appui contre un épaulement 8a d'un embout 8e fixé à l'extrémité inférieure de la tige de commande 8.A control rod 8 is slidably mounted at its lower part in the body 6 against the action of a return spring 9 working in compression, one end of this spring 9 bearing against a shoulder 10 at the bottom of the lower part 6 b of the body 6 and the other end bearing against a shoulder 8 a of a nozzle 8 e fixed to the lower end of the control rod 8.

La partie supérieure 6a présente une bride 18 servant au montage de la pompe 5 et un joint d'étanchéité 14 situé sous cette bride permet une fixation étanche sur le récipient, au moyen d'une bague métallique 7 sertissable sur le col 4 du récipient 2.The upper part 6 a has a flange 18 used for mounting the pump 5 and a seal 14 located under this flange allows a tight fixing on the container, by means of a metal ring 7 crimpable on the neck 4 of the container 2.

La tige de commande 8 est parcourue par un évidement axial 8d s'étendant au-dessus de l'embout 8e jusqu'à son extrémité supérieure.The control rod 8 is traversed by an axial recess 8 d extending above the nozzle 8 e to its upper end.

Un embout de distribution 19 servant à la fois d'organe d'actionnement et de buse est emmanché à force sur l'extrémité supérieure de la tige de commande 8.A dispensing nozzle 19 serving both as an organ actuation and nozzle is force fitted on the end upper of control rod 8.

Un piston 11 est monté autour de la tige de commande 8 à l'intérieur de la partie inférieure 6b du corps 6.A piston 11 is mounted around the control rod 8 inside the lower part 6b of the body 6.

Ce piston 11 coulisse à la fois au contact de la partie inférieure 6b et au contact de la tige de commande 8 et présente un épaulement intérieur 11a contre lequel vient appuyer un épaulement 8b de la tige de commande 8 après une légère course d'enfoncement de cette dernière. This piston 11 slides both in contact with the lower part 6 b and in contact with the control rod 8 and has an internal shoulder 11 a against which abuts a shoulder 8 b of the control rod 8 after a slight stroke d sinking of the latter.

Le piston 11 présente en partie inférieure une jupe 11b contre laquelle prend appui l'embout 8e de la tige de commande 8 lorsqu'elle est au repos, c'est-à-dire lorsqu'elle vient en butée par un épaulement 8f situé au-dessus du piston 11 contre un rétreint 17 de la partie supérieure 6a.The piston 11 has in the lower part a skirt 11 b against which the end piece 8 e of the control rod 8 bears when it is at rest, that is to say when it comes into abutment with a shoulder 8 f located above the piston 11 against a constriction 17 of the upper part 6 a .

La tige de commande 8 comporte des perçages radiaux 8c communiquant avec l'évidement axial 8d à son extrémité inférieure et permettant d'acheminer le produit jusqu'à l'embout de distribution 19.The control rod 8 has radial holes 8 c communicating with the axial recess 8 d at its lower end and making it possible to convey the product to the dispensing nozzle 19.

La partie inférieure 6b sert de siège à une bille 13 obturant au repos un orifice 26.The lower part 6 b serves as a seat for a ball 13 closing at rest an orifice 26.

Le piston 11 et la bille 13 délimitent une chambre de pompage 12 à l'intérieur du corps 6.The piston 11 and the ball 13 delimit a pumping 12 inside the body 6.

Lorsque la tige de commande 8 est au repos, les perçages 8c sont obturés par la jupe 11b du piston 11.When the control rod 8 is at rest, the holes 8 c are closed by the skirt 11 b of the piston 11.

Lorsque l'utilisateur appuie sur l'embout de distribution 19, la tige de commande 8 s'enfonce dans le corps 6.When the user presses on the dispensing nozzle 19, the control rod 8 sinks into the body 6.

Au début de la course d'enfoncement de la tige de commande 8, le piston 11 n'est pas entraíné par la tige de commande 8 tant qu'il n'y a pas butée de l'épaulement 8b contre l'épaulement 11a du piston 11.At the start of the depressing stroke of the operating rod 8, the piston 11 is not driven by the control rod 8 so that there is no abutment of the shoulder 8 b against the shoulder 11 has piston 11.

La tige de commande 8 se déplace donc relativement au piston 11 et l'embout 8e cesse d'être en appui sur la jupe 11b.The control rod 8 therefore moves relative to the piston 11 and the end piece 8 e ceases to be supported on the skirt 11 b .

Les perçages 8c communiquent alors avec la chambre de pompage 12 par l'intervalle existant entre la tige de commande 8 et le bord inférieur de la jupe 11b.The holes 8 c then communicate with the pumping chamber 12 through the gap existing between the control rod 8 and the lower edge of the skirt 11 b .

Lors de la poursuite de la course d'enfoncement de la tige de commande 8, l'épaulement 8b vient en appui contre l'épaulement 11a et le piston 11 est déplacé vers le bas conjointement à la tige de commande 8.When the continuation of the stroke of depression of the control rod 8, the shoulder 8b abuts against the shoulder 11a and the piston 11 is moved downward together with the operating rod 8.

Le produit est alors chassé de la chambre de pompage 12 par le mouvement du piston 11 et gagne l'évidement axial 8d par les perçages 8c, pour être distribué.The product is then expelled from the pumping chamber 12 by the movement of the piston 11 and gains the axial recess 8 d by the holes 8 c , to be dispensed.

Au cours de la descente de la tige de commande 8, la bille 13 reste en appui contre son siège dans le fond de la partie inférieure 6b du corps 6 et évite que le produit ne soit refoulé dans le réservoir. During the descent of the control rod 8, the ball 13 remains in abutment against its seat in the bottom of the lower part 6b of the body 6 and prevents the product from being pushed back into the tank.

Lorsque l'utilisateur relâche l'embout de distribution 19, la tige de commande 8 coulisse tout d'abord dans le piston 11 jusqu'à venir en appui par l'embout 8e contre le bord inférieur de la jupe 11b.When the user releases the dispensing end piece 19, the control rod 8 slides first in the piston 11 until it comes to bear by the end piece 8 e against the lower edge of the skirt 11 b .

L'évidement axial 8d est alors isolé de la chambre de pompage 12, et la poursuite du mouvement de remontée de la tige de commande 8 sous l'action du ressort 9 provoque une dépression dans la chambre de pompage 12, laquelle s'accompagne du soulèvement de la bille 13 et de l'arrivée de produit depuis le réservoir.The axial recess 8 d is then isolated from the pumping chamber 12, and the continued upward movement of the control rod 8 under the action of the spring 9 causes a vacuum in the pumping chamber 12, which is accompanied the lifting of the ball 13 and the arrival of product from the reservoir.

Les inventeurs ont constaté qu'avec les pompes connues, si le vide est réalisé dans le réservoir préalablement à son remplissage, la bille 13 n'assure pas une fermeture suffisamment étanche de la chambre de pompage 12, de sorte que l'air présent dans celle-ci est aspiré.The inventors have found that with known pumps, if the vacuum is created in the tank before filling, the ball 13 does not ensure a sufficiently tight closure of the chamber pumping 12, so that the air present therein is sucked.

En particulier, si le remplissage du réservoir a lieu tête en bas, la bille 13 quitte son siège par gravité et ne peut aucunement isoler la chambre de pompage 12.In particular, if the filling of the tank takes place head to bottom, ball 13 leaves its seat by gravity and cannot in any way isolate the pumping chamber 12.

Il en résulte que lorsque le réservoir en dépression est mis en communication avec la source de produit pour son remplissage, du produit se trouve également aspiré dans la chambre de pompage 12 en raison de la dépression régnant dans celle-ci.It follows that when the vacuum tank is put in communication with the product source for filling, product is also sucked into pumping chamber 12 in because of the depression prevailing in it.

L'invention permet de remédier à cet inconvénient.The invention overcomes this drawback.

On a représenté sur la figure 3, en coupe axiale schématique, un premier exemple de réalisation d'une pompe selon l'invention, laquelle porte la référence 22 et diffère de la pompe 5 précédemment décrite par le fait que la partie inférieure du corps de la pompe, référencée ici 6b', présente une gorge annulaire extérieure 28 et par le fait qu'elle est munie d'un clapet anti-vide 23 assujetti à une pièce de support 24, laquelle est fixée par encliquetage dans la gorge 28.There is shown in Figure 3, in schematic axial section, a first embodiment of a pump according to the invention, which has the reference 22 and differs from the pump 5 previously described in that the lower part of the body of the pump, referenced here 6 b ′, has an external annular groove 28 and by the fact that it is provided with an anti-vacuum valve 23 secured to a support piece 24, which is fixed by snap-fastening in the groove 28.

Le clapet anti-vide 23 est spécialement conçu pour empêcher que l'air initialement présent dans la chambre de pompage 12 soit aspiré lors de la mise en dépression du réservoir pour son remplissage.The vacuum valve 23 is specially designed to prevent the air initially present in the pumping chamber 12 is sucked when the tank is placed under vacuum for filling.

Le clapet anti-vide 23 est réalisé, dans l'exemple décrit, en matériau élastomère, étant surmoulé sur la pièce de support 24 ou en variante réalisé par bi-injection avec celle-ci.The anti-vacuum valve 23 is produced, in the example described, by elastomeric material, being overmolded on the support piece 24 or in variant made by bi-injection therewith.

La pièce de support 24 est percée d'un orifice 25 obturé au repos par le clapet anti-vide 23 et permettant au produit de gagner l'orifice 26 lorsque la tige de commande 8 remonte. The support piece 24 is pierced with an orifice 25 closed at rest by the anti-vacuum valve 23 and allowing the product to gain the orifice 26 when the control rod 8 rises.

L'orifice 25 est obturé avec l'étanchéité nécessaire par le clapet 23, même lorsque le réservoir est tête en bas et qu'il est mis en dépression.The orifice 25 is closed with the necessary seal by the valve 23, even when the tank is upside down and put on in depression.

Bien que la pompe 22 soit représentée avec la bille 13, cette dernière pourrait être supprimée, le clapet 23 faisant alors également office de clapet d'aspiration dans ce cas.Although the pump 22 is shown with the ball 13, this last could be deleted, the valve 23 also doing suction valve in this case.

On va maintenant décrire, en référence aux figures 4 à 7, les différentes étapes du processus de remplissage par le vide du réservoir, ainsi que la mise en place de l'embout de distribution sur la tige de commande.We will now describe, with reference to FIGS. 4 to 7, the different stages of the vacuum filling process of the tank, as well as the installation of the dispensing nozzle on the control rod.

Tout d'abord, comme représenté sur la figure 4, le récipient 2 est disposé à l'envers, puis la tête T d'une remplisseuse sous vide est appliquée de façon étanche contre le fond du récipient 2.First, as shown in Figure 4, the container 2 is arranged upside down, then the head T of a vacuum filler is applied tightly against the bottom of the container 2.

L'air est alors aspiré dans celui-ci au travers d'un canal de la tête T.The air is then sucked into it through a channel of the head T.

Durant l'étape de création du vide dans le récipient 2, le clapet 23 est fermement plaqué contre son siège sur la pièce de support 24 et empêche l'air contenu dans la chambre de pompage 12 de s'échapper.During the step of creating the vacuum in the container 2, the valve 23 is firmly pressed against its seat on the workpiece support 24 and prevents the air contained in the pumping chamber 12 from escape.

Le vide créé dans le récipient 2 n'est que relatif, et il suffit conformément à l'invention que le remplissage ait lieu sous une pression inférieure à la pression atmosphérique.The vacuum created in container 2 is only relative, and it it is sufficient in accordance with the invention that the filling takes place under a pressure below atmospheric pressure.

Ensuite, comme illustré sur la figure 5, l'intérieur du récipient 2 est mis en communication avec une source de produit P, et ce dernier gagne, par l'intermédiaire de la tête T, l'intérieur du récipient, comme illustré sur la figure 5.Then, as illustrated in Figure 5, the interior of the container 2 is placed in communication with a source of product P, and the latter gains, via the head T, the interior of the container, as illustrated in figure 5.

Comme la chambre de pompage 12 n'est pas en dépression, le produit n'est pas aspiré dans celle-ci.As the pumping chamber 12 is not under vacuum, the product is not drawn into it.

Une fois le récipient 2 rempli, le fond mobile constitué par le piston 3 est mis en place, comme illustré à la figure 6.Once the container 2 is filled, the movable bottom formed by the piston 3 is put in place, as illustrated in figure 6.

Ensuite, le récipient 2 est retourné et l'embout 19 peut être fixé sur la tige de commande 8, comme illustré à la figure 7.Then the container 2 is turned over and the end piece 19 can be fixed on the control rod 8, as illustrated in Figure 7.

L'enfoncement de la tige de commande 8 qui accompagne la mise en place de l'embout 19 ne provoque aucune sortie de produit, du fait que la chambre de pompage 12 n'en contient pas.The depression of the control rod 8 which accompanies the setting in place of the end piece 19 does not cause any product to escape, because that the pumping chamber 12 does not contain any.

Dans l'exemple de réalisation qui vient d'être décrit, le clapet anti-vide 23 est rapporté sur la pompe, laquelle ne diffère des pompes connues que par une modification mineure, à savoir la présence de la gorge 28.In the embodiment which has just been described, the anti-vacuum valve 23 is attached to the pump, which does not differ from the pumps known only by a minor modification, namely the presence throat 28.

Dans la variante de réalisation représentée sur la figure 8, le clapet anti-vide, référencé 30, fait partie intégrante de la pompe, étant surmoulé sur le corps de cette dernière, référencé 31, ou réalisé par bi-injection avec celui-ci.In the variant embodiment shown in FIG. 8, the anti-vacuum valve, referenced 30, is an integral part of the pump, being molded onto the body of the latter, referenced 31, or made by bi-injection with it.

Le clapet anti-vide 30 remplace la bille 13 de la pompe 5 précédemment décrite et permet une meilleure étanchéité que celle-ci vis-à-vis du vide créé dans le réservoir préalablement à son remplissage. La pompe est similaire pour le restant.The anti-vacuum valve 30 replaces the ball 13 of the pump 5 previously described and allows a better seal than this vis-à-vis the vacuum created in the tank prior to its filling. The pump is similar for the rest.

Une fois le réservoir rempli, le clapet 30 fonctionne de la même manière que la bille 13 en permettant au produit de gagner la chambre de pompage 12 lors de la remontée de la tige de commande et d'empêcher le produit d'être refoulé dans le réservoir lorsque l'utilisateur appuie sur l'embout de distribution 19.Once the tank is filled, the valve 30 operates from the same way as ball 13 by allowing the product to gain the pumping chamber 12 when raising the control rod and prevent the product from being returned to the tank when the user presses on the dispensing nozzle 19.

Dans une autre variante, représentée sur la figure 9, le clapet anti-vide, référencé 35, est réalisé sur une pièce de support indépendante 36.In another variant, shown in FIG. 9, the valve anti-vacuum, referenced 35, is produced on a support piece independent 36.

La pompe, référencée 31, est fixée sur cette pièce de support 36.The pump, referenced 31, is fixed on this support piece 36.

La pompe 37 est identique à la pompe 5 représentée sur la figure 2, mis à part le fait qu'elle ne comporte pas de joint d'étanchéité 14, la bride 18 de la partie supérieure 6a du corps de la pompe reposant directement sur une pièce intermédiaire 38, contre laquelle elle est maintenue par sertissage de la bague 7.The pump 37 is identical to the pump 5 shown in Figure 2, except that it has no gasket 14, the flange 18 of the upper part 6a of the body of the pump resting directly on an intermediate piece 38, against which it is held by crimping the ring 7.

La pièce intermédiaire 38 comporte à sa partie supérieure une bride 38a qui vient en appui contre la bride 18 et présente en partie inférieure une jupe 38b s'étendant concentriquement à la partie inférieure 6b du corps de la pompe.The intermediate piece 38 has at its upper part a flange 38 a which bears against the flange 18 and has in the lower part a skirt 38 b extending concentrically with the lower part 6 b of the pump body.

La pièce de support 36 comporte une jupe d'étanchéité 36a conformée pour s'appliquer de façon étanche sur la partie inférieure 6b du corps de la pompe, dans l'espace annulaire existant entre cette partie inférieure 6b et la jupe 38b.The support piece 36 comprises a sealing skirt 36 a shaped to apply in a sealed manner on the lower part 6 b of the pump body, in the annular space existing between this lower part 6 b and the skirt 38 b .

La pièce de support 36 comporte également une jupe 36b servant à la fixation de la pièce intermédiaire 38, pourvue d'une gorge annulaire 36c dans laquelle s'encliquette un bourrelet 38c réalisé sur la surface radialement extérieure de la jupe 38b. The support piece 36 also includes a skirt 36 b used for fixing the intermediate piece 38, provided with an annular groove 36 c into which a bead 38 c is engaged, formed on the radially outer surface of the skirt 38 b .

La pièce de support 36 comporte enfin une jupe extérieure 36d munie à l'extrémité supérieure d'un rebord 36e, cette jupe 36d étant destiné à la fixation de l'ensemble sur un boítier et servant également à la fixation d'une poche 40 souple déformable formant réservoir.The support piece 36 finally comprises an outer skirt 36 d provided at the upper end with a flange 36 e , this skirt 36 d being intended for fixing the assembly to a housing and also serving for fixing a flexible deformable pocket 40 forming a reservoir.

Le clapet anti-vide 35 est réalisé par surmoulage dans un logement 41 de la pièce de support 36, débouchant à l'intérieur de la jupe d'étanchéité 36a sous l'orifice 26 de la pompe.The anti-vacuum valve 35 is produced by overmoulding in a housing 41 of the support piece 36, opening into the interior of the sealing skirt 36 beneath the orifice 26 of the pump.

Le clapet anti-vide 35 comporte une partie fixe 35a fixée sur la paroi latérale de ce logement 41 et une partie mobile 35b reliée à la partie fixe par un pont de matière 35c formant charnière, la partie mobile 35b pouvant se soulever pour permettre le passage du produit vers la pompe 37. Au repos, la partie mobile 35b obture l'orifice prévu dans le fond du logement 41.The anti-vacuum valve 35 has a fixed part 35 a fixed on the side wall of this housing 41 and a mobile part 35 b connected to the fixed part by a material bridge 35 c forming a hinge, the mobile part 35 b being able to lift to allow the passage of the product towards the pump 37. At rest, the movable part 35 b closes the orifice provided in the bottom of the housing 41.

Le clapet anti-vide peut également, en variante, être réalisé sur une pièce de support 45 ne servant qu'à la fixation d'une poche 46 formant réservoir, comme illustré sur la figure 10.The anti-vacuum valve can also, as a variant, be produced on a support piece 45 used only for fixing a pocket 46 forming a reservoir, as illustrated in FIG. 10.

Cette pièce de support 45 présente en coupe axiale la forme générale d'un U, étant pourvue en son fond d'un orifice central 47.This support piece 45 has in axial section the shape general of a U, being provided at its bottom with a central orifice 47.

Le clapet anti-vide, référencé ici 48, est fixé sur la pièce de support 45 de manière à obturer l'orifice 47 lorsque le vide est réalisé dans la poche 46.The anti-vacuum valve, referenced here 48, is fixed on the part of support 45 so as to close the orifice 47 when the vacuum is made in pocket 46.

La poche 46 est fixée par tout moyen connu sur la surface extérieure de la paroi latérale 49 de la pièce de support 45, par exemple par soudage aux ultrasons.The pocket 46 is fixed by any known means on the surface outside of the side wall 49 of the support piece 45, by example by ultrasonic welding.

La paroi latérale 49 se prolonge radialement vers l'extérieur, à son extrémité supérieure, pour former une collerette destinée à sa fixation à l'intérieur d'un boítier portant au-dessus de la pièce de support 45 la pompe permettant de prélever le produit contenu dans la poche.The side wall 49 extends radially outwards, at its upper end, to form a collar intended for its fixing inside a housing bearing above the piece of support 45 the pump allowing the product contained in the poached.

L'invention s'applique encore à une pompe telle que celle représentée sur la figure 11, référencée 60.The invention also applies to a pump such as that shown in Figure 11, referenced 60.

Cette pompe 60 comporte un clapet de refoulement 61 formé à l'extrémité extérieure du canal de sortie de l'embout de distribution 62.This pump 60 includes a discharge valve 61 formed at the outer end of the outlet channel of the nozzle distribution 62.

L'embout de distribution 62 est réalisé d'un seul tenant avec la tige de commande, laquelle comporte une double paroi. The dispensing nozzle 62 is made in one piece with the control rod, which has a double wall.

Le corps de la pompe, référencé 65, comporte une paroi centrale 70 cylindrique de révolution, laquelle se prolonge vers l'extérieur à son extrémité inférieure pour former une gorge en U ouverte vers le haut, servant de guide pour le coulissement de la double paroi de l'embout de distribution 62.The pump body, referenced 65, has a central wall 70 cylindrical of revolution, which extends outwards to its lower end to form a U-shaped groove open towards the high, serving as a guide for sliding the double wall of the dispensing nozzle 62.

La paroi 67 radialement la plus extérieure coulisse au contact de la paroi 68 radialement la plus extérieure du corps 65 et la paroi 69 radialement la plus intérieure coulisse au contact de la paroi 70.The radially outermost wall 67 slides in contact from the radially outermost wall 68 of the body 65 and the wall 69 radially innermost slides in contact with the wall 70.

Cette dernière se prolonge vers le haut en se rétrécissant pour définir à son extrémité supérieure un orifice 71, lequel est obturé par un clapet 63 lorsque l'embout de distribution 62 est enfoncé dans le corps 65.The latter extends upward, narrowing to define at its upper end an orifice 71, which is closed by a valve 63 when the dispensing nozzle 62 is pressed into the body 65.

Un joint d'étanchéité 72 est réalisé à la périphérie du clapet 63 pour assurer le coulissement étanche de la paroi 69 sur la paroi 70.A seal 72 is produced at the periphery of the valve 63 to ensure the tight sliding of the wall 69 on the wall 70.

Une gorge annulaire 73 est réalisée sur la surface radialement intérieure de la paroi 68 pour retenir des reliefs 74 formant saillie radialement vers l'extérieur sur la paroi 67 et limiter la course vers le haut de l'embout de distribution.An annular groove 73 is formed on the surface radially inside of wall 68 to retain reliefs 74 projecting radially outward on the wall 67 and limit the stroke towards the top of the dispensing nozzle.

Un ressort 75, travaillant en compression, s'applique à une extrémité dans le fond de la gorge formée entre les parois 67 et 69 et à l'autre extrémité dans le fond de la gorge formée entre les parois 60 et 70.A spring 75, working in compression, is applied to a end in the bottom of the groove formed between the walls 67 and 69 and at the other end in the bottom of the groove formed between the walls 60 and 70.

La chambre de pompage est constituée ici par le canal intérieur de l'embout de distribution 62, ce canal étant délimité à l'extérieur par le clapet 61 et à l'intérieur par le clapet 63.The pumping chamber here consists of the inner channel of the distribution nozzle 62, this channel being delimited on the outside by the valve 61 and inside by the valve 63.

Une poche déformable 77 est fixée sur la surface radialement extérieure de la paroi 68.A deformable pocket 77 is fixed on the surface radially exterior of the wall 68.

En variante, la pompe 60 est fixée, moyennant des modifications mineures du corps 65, sur un récipient 2 à fond mobile tel que précédemment décrit.Alternatively, the pump 60 is fixed, subject to modifications body 65, on a container 2 with a movable bottom such as previously described.

Dans les pompes connues, le clapet d'aspiration 63 n'est pas prévu pour assurer une étanchéité vis-à-vis du vide.In known pumps, the suction valve 63 is not designed to ensure a seal against the vacuum.

Selon l'invention, un clapet anti-vide 80 porté par une pièce de support 81 est assujetti au corps 65, par tout moyen connu de l'homme du métier. According to the invention, an anti-vacuum valve 80 carried by a part support 81 is subject to the body 65, by any known means of the skilled person.

On a illustré sur les figures 12 à 18, la manière de remplir et de fermer une poche souple formant réservoir.Figures 12 to 18 illustrate the manner of filling and to close a flexible pocket forming a reservoir.

La poche souple, référencée 90, est préalablement fixée sur un support ou sur une pompe, muni d'un clapet anti-vide selon l'invention.The flexible pocket, referenced 90, is previously fixed on a support or on a pump, fitted with an anti-vacuum valve according to the invention.

L'ensemble est supporté par un dispositif de maintien 91 sur lequel on vient rapporter une cloche 92 traversée par une buse de remplissage 93.The assembly is supported by a holding device 91 on which one comes to bring a bell 92 crossed by a nozzle of filling 93.

La cloche 92 est munie de moyens 94 partiellement représentés permettant de contrôler la dépression régnant à l'intérieur.The bell 92 is provided with means 94 partially shown to control the internal depression.

La cloche 92 est mise sous dépression par aspiration de l'air contenu à l'intérieur, cet air quittant le fond du dispositif 91 par un conduit 95.The bell 92 is put under vacuum by air suction contained inside, this air leaving the bottom of the device 91 by a conduit 95.

La poche 90 présente un fond 96 ouvert vers le haut, comme représenté sur la figure 12.The pocket 90 has a bottom 96 open upwards, as shown in figure 12.

Une fois que la cloche 92 est sous dépression, le produit P est distribué par la buse 93. La cloche 92 et le dispositif de maintien 91 descendent relativement à la buse tandis que le niveau du produit P dans la poche 90 monte, comme représenté sur la figure 13, de manière à maintenir l'extrémité inférieure de la buse 93 au-dessus du produit dans la poche.Once the bell 92 is under vacuum, the product P is distributed by the nozzle 93. The bell 92 and the holding device 91 descend relatively to the nozzle while the level of the product P in the pocket 90 rises, as shown in Figure 13, so to maintain the lower end of the nozzle 93 above the product in the pocket.

La cloche 92 est maintenue sous dépression tant que dure le remplissage.The bell 92 is kept under vacuum as long as the filling.

A la fin du remplissage, comme illustré sur la figure 14, la buse 93 se situe hors de la poche, et le vide est cassé en permettant une rentrée d'air par le conduit 95.At the end of filling, as illustrated in Figure 14, the nozzle 93 is located outside the pocket, and the vacuum is broken allowing an air intake through the conduit 95.

Ensuite, la cloche 92 est enlevée et la poche 90 remplie est amenée à un poste de fermeture muni d'un dispositif 97 de pincement et de scellage, comme illustré sur la figure 15.Then the bell 92 is removed and the filled pocket 90 is brought to a closing station provided with a pinching device 97 and seal, as shown in Figure 15.

Le fond 96 est pincé et scellé en deux emplacements l'un au-dessus de l'autre, comme illustré sur les figures 16 et 17, puis la partie de la poche qui se trouve entre ces deux lignes de scellage est découpée, comme illustré sur la figure 18.Bottom 96 is pinched and sealed in two locations one above each other, as shown in Figures 16 and 17, then the part of the pocket between these two sealing lines is cut out, as shown in figure 18.

L'invention est avantageusement mise en oeuvre pour réaliser un dispositif de conditionnement et de distribution tel que celui représenté sur la figure 19, comportant deux pompes munies chacune d'un clapet anti-vide, telles que les pompes 37 décrites en référence à la figure 9, associées chacune à une poche souple 40 formant réservoir, les poches étant placées à l'intérieur d'un même boítier 100.The invention is advantageously implemented to produce a packaging and distribution device such as that shown in Figure 19, comprising two pumps each provided an anti-vacuum valve, such as the pumps 37 described with reference in FIG. 9, each associated with a flexible pocket 40 forming tank, the pockets being placed inside a single case 100.

Chaque poche 40 est remplie individuellement par le procédé décrit en référence aux figures 12 à 18.Each pocket 40 is filled individually by the process described with reference to Figures 12 to 18.

Une fois les deux pompes 37 mises en place dans le boítier 100, un embout de distribution 101 commun est rapporté sur les tiges de commande 8.Once the two pumps 37 are in place in the housing 100, a common distribution nozzle 101 is attached to the rods of command 8.

Cet embout de distribution 101 comporte deux logements 102 et 103 venant s'emmancher sur les extrémités des tiges de commande 8 et communiquant avec une buse de sortie, non représentée dans un souci de clarté du dessin.This dispensing nozzle 101 has two housings 102 and 103 coming to be fitted on the ends of the control rods 8 and communicating with an outlet nozzle, not shown for the sake of clarity of the drawing.
