Description

Pompe pour distribution de produit liquide sans reprise d'air et distributeur associé Pump for dispensing liquid product without air intake and associated dispenser
La présente invention concerne une pompe pour distribution de produit liquide sans reprise d'air et un distributeur utilisant cette pompe.The present invention relates to a pump for dispensing liquid product without air intake and a dispenser using this pump.
Cette pompe est plus particulièrement destinée à être montée sur un réservoir de produits cosmétiques ou pharmaceutiques liquides, sous forme de crème ou de gel, fermé à sa partie inférieure par un fond mobile.This pump is more particularly intended to be mounted on a tank of cosmetic or pharmaceutical liquid products, in the form of cream or gel, closed at its bottom by a movable bottom.
Les pompes de ce type comprennent généralement un corps dans lequel est logé un piston qui vient fermer en position de fin de course un orifice ménagé à la partie basse dudit corps et qui est équipé d'un clapet d'admission tel qu'un clapet à bille.Pumps of this type generally comprise a body in which is housed a piston which closes in the end-of-travel position an orifice formed in the lower part of said body and which is equipped with an intake valve such as a valve. ball.
La pompe décrite notamment dans le EP 0 737 628 est dépourvue de clapet d'admission et de corps; le piston se déplaçant directement au contact de la paroi du col du réservoir. Toutefois, le piston est dans ce cas constitué d'une membrane élastiquement déformable dont le procédé de fabrication est complexe et onéreux et qui présente une faible résistance mécanique ainsi qu'une stabilité dimensionnelle aléatoire.The pump described in particular in EP 0 737 628 is devoid of intake valve and body; the piston moving directly in contact with the wall of the neck of the tank. However, the piston is in this case constituted by an elastically deformable membrane whose manufacturing process is complex and expensive and which has a low mechanical strength as well as a random dimensional stability.
En outre, avec les pompes traditionnelles, il est nécessaire d'appliquer une pression relativement forte au produit pour obtenir sa sortie ce qui implique une course importante du piston et conduit souvent à la délivrance brutale de doses excessives.In addition, with traditional pumps, it is necessary to apply a relatively high pressure to the product to obtain its output which involves a significant stroke of the piston and often leads to the sudden delivery of excessive doses.
Or, le consommateur souhaite que la délivrance du produit s'effectue de façon douce et régulière de façon à pouvoir contrôler le dosage.However, the consumer wants the delivery of the product is carried out smoothly and regularly so as to control the dosage.
La présente invention a pour but de résoudre les problèmes techniques soulevés par les pompes antérieures de ce type.The present invention aims to solve the technical problems raised by prior pumps of this type.
Ce but est atteint selon l'invention au moyen d'une pompe comprenant un corps cylindrique ouvert à sa partie inférieure et fermé à sa partie supérieure par un piston constitué d'une bague montée, d'une part, autour de la partie inférieure d'un tube- gicleur central, avec un jeu axial entre deux butées respectivement haute et basse, en regard d'au moins un orifice d'éjection ménagé sur ledit tube, et coulissant, d'autre part, en contact de friction avec la paroi interne dudit corps.This object is achieved according to the invention by means of a pump comprising a cylindrical body open at its lower part and closed at its upper part by a piston consisting of a ring mounted on the one hand, around the lower part of a central tube-jet, with axial clearance between two stops respectively high and low, in viewing at least one ejection orifice formed on said tube, and sliding, on the other hand, in frictional contact with the inner wall of said body.
Selon une caractéristique avantageuse, ledit corps comporte, en partie haute, une douille intérieure pourvue d'un collier supérieur de guidage du tube-gicleur et d'un collier inférieur de blocage du piston en position d'obturation de l'orifice d'éjection.According to an advantageous characteristic, said body comprises, at the top, an inner sleeve provided with an upper collar for guiding the nozzle tube and a lower collar for locking the piston in the closed position of the ejection orifice. .
Selon une variante spécifique, ladite bague du piston présente un anneau intérieur cylindro-conique dont les tronçons supérieur et inférieur viennent alternativement, en fonction de la pression du liquide, en contact avec les butées haute et basse du tube- gicleur de façon à ouvrir ou à fermer l'orifice d'éjection de manière étanche à la manière d'un clapet.According to a specific variant, said piston ring has a cylindro-conical inner ring whose upper and lower sections alternately, depending on the pressure of the liquid, in contact with the upper and lower stops of the nozzle-tube so as to open or closing the ejection orifice sealingly in the manner of a valve.
De préférence, la face supérieure de ladite bague comporte une nervure circulaire délimitant, avec le tronçon supérieur de l'anneau intérieur, une gorge dans laquelle vient s'engager le collier inférieur de blocage du piston.Preferably, the upper face of said ring comprises a circular rib delimiting, with the upper portion of the inner ring, a groove in which is engaged the lower clamping collar of the piston.
Selon une autre variante, l'extrémité inférieure du -tube-gicleur porte une^base tronconique à bord plat dont la face supérieure forme la butée basse de la bague dudit piston, en dessous du niveau de l'orifice d'éjection.According to another variant, the bottom of the nozzle-tube-end carries a ^ frustoconical base flat edge of which the upper face forms the lower stop of the ring of said piston, below the level of the ejection orifice.
Selon encore une autre variante, la partie inférieure du tube-gicleur porte un épaulement périphérique dont la face inférieure forme la butée haute de la bague dudit piston, au dessus du niveau de l'orifice d'éjection.According to yet another variant, the lower part of the nozzle tube carries a peripheral shoulder whose lower face forms the upper stop of the ring of said piston, above the level of the ejection orifice.
Selon encore une autre caractéristique, ledit corps est solidaire, via une entretoise transversale, d'une collerette périphérique de fixation sur un réservoir.According to yet another characteristic, said body is secured, via a transverse spacer, a peripheral fastening flange on a tank.
Avantageusement, ladite collerette se prolonge vers le haut par un rebord en saillie susceptible de recevoir, par l'extérieur, un capot et, par l'intérieur, la jupe d'un bouton- poussoir de distributeur. II est aussi prévu que ladite entretoise transversale puisse être pourvue d'un méplat latéral formant butée de fin de course pour la jupe du bouton-poussoir de façon à définir un volume de dosage.Advantageously, said flange extends upwardly by a projecting flange capable of receiving, from the outside, a cover and, from the inside, the skirt of a distributor push button. It is also envisaged that said transverse spacer may be provided with a lateral flat end stop forming a stop for the skirt of the push button so as to define a dosing volume.
Un autre objet de l'invention est un distributeur comprenant notamment, la pompe selon l'invention ainsi qu'un réservoir de produit.Another object of the invention is a dispenser comprising, in particular, the pump according to the invention as well as a product reservoir.
Selon une caractéristique avantageuse de ce distributeur, l'extrémité supérieure du tube- gicleur de la pompe est raccordée à un conduit d'échappement ménagé dans un bouton- poussoir pourvu d'une jupe externe et d'un manchon cylindrique interne destiné à coiffer ledit corps de manière coulissante en emprisonnant un ressort de rappel hélicoïdal dans l'espace intercalaire tandis que le réservoir est obturé de manière étanche, en partie basse, par un fond mobile.According to an advantageous characteristic of this distributor, the upper end of the pump nozzle is connected to an exhaust duct formed in a push-button provided with an external skirt and an internal cylindrical sleeve intended to cover said nozzle. sliding body by trapping a helical return spring in the spacer space while the reservoir is sealed at the bottom, by a movable bottom.
Selon une caractéristique spécifique du distributeur, la résistance de frottement entre la bague et la paroi interne du corps de la pompe, d'une part, et la résistance de frottement entre le fond mobile et la paroi du réservoir, d'autre part, sont supérieurs à la résistance de frottement entre la bague etle tube de ladite pompe.According to a specific characteristic of the distributor, the frictional resistance between the ring and the inner wall of the pump body, on the one hand, and the frictional resistance between the movable bottom and the tank wall, on the other hand, are greater than the frictional resistance between the ring and the tube of said pump.
De préférence, ledit fond mobile comporte une coupelle centrale dont le profil est complémentaire de celui de la base tronconique du tube-gicleur et/ou de la partie inférieure dudit corps de la pompe.Preferably, said movable bottom has a central cup whose profile is complementary to that of the frustoconical base of the nozzle tube and / or the lower part of said body of the pump.
Là pompe de l'invention possède une structure simplifiée et très compacte du fait, notamment, que le nombre de pièces constitutives est très réduit.The pump of the invention has a simplified and very compact structure, in particular because the number of component parts is very small.
En particulier, le corps de pompe est un cylindre ouvert en partie basse et dépourvu d'un quelconque clapet ce qui facilite les opérations de fabrication par moulage.In particular, the pump body is an open cylinder at the bottom and devoid of any valve which facilitates manufacturing operations by molding.
La délivrance du produit s'effectue de façon régulière, ergonomique et contrôlée par un appui léger du consommateur sur le bouton-poussoir du distributeur et sans qu'il soit nécessaire d'appliquer une pression élevée sur le produit. En effet, le diamètre de la partie inférieure du corps correspond au diamètre du piston et il n'existe donc pas de restriction de la surface de compression ou de la section de passage du produit dans la zone de prise.The delivery of the product is carried out regularly, ergonomically and controlled by a light consumer support on the push button of the dispenser and without the need to apply a high pressure on the product. Indeed, the diameter of the lower part of the body corresponds to the diameter of the piston and there is therefore no restriction of the compression surface or the product passage section in the gripping zone.
II en résulte de manière avantageuse que cette pression faible n'est pas suffisante pour provoquer le retour du fond mobile qui reste donc toujours au contact du produit dans le réservoir.It advantageously results that this low pressure is not sufficient to cause the return of the movable bottom which always remains in contact with the product in the tank.
Les risques de dysfonctionnement du distributeur sont ainsi écartés et l'étanchéité du réservoir est préservée.The risks of malfunction of the dispenser are thus removed and the watertightness of the reservoir is preserved.
La présente invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels;The present invention will be better understood on reading the description which follows with reference to the drawings in which;
Les figures IA et IB sont des vues en coupe axiale d'un mode de réalisation de la pompe de l'invention, respectivement en position de repos (avec le capot) et en position de distribution (sans le capot).FIGS. 1A and 1B are views in axial section of an embodiment of the pump of the invention, respectively in the rest position (with the cover) and in the dispensing position (without the cover).
Les figures 2 à 5 sont des vues de détail en coupe de la pompe des figures IA, IB lors des différentes phases de la distribution du produit.Figures 2 to 5 are detailed sectional views of the pump of Figures IA, IB during the different phases of the product distribution.
Le distributeur représenté sur les figures IA et IB est destiné à la délivrance et au dosage de produits liquides sans reprise d'air dans le réservoir.The distributor shown in Figures IA and IB is intended for the delivery and dosing of liquid products without air intake into the tank.
Le produit est donc maintenu dans une atmosphère confinée, à l'abri de l'environnement extérieur en étant préservé de toute pollution ou contamination ce qui est impératif pour des produits sensibles tels que les produits cosmétiques ou pharmaceutiques.The product is therefore kept in a confined atmosphere, protected from the outside environment while being protected from any pollution or contamination which is imperative for sensitive products such as cosmetic or pharmaceutical products.
Ce distributeur est équipé d'une pompe P comprenant un corps cylindrique 1 ouvert à plein diamètre à sa partie inférieure où il débouche dans un réservoir R de produit obturé par un fond mobile F.This dispenser is equipped with a pump P comprising a cylindrical body 1 open at full diameter at its lower part where it opens into a tank R of product closed by a movable bottom F.
Le réservoir R comporte ici en outre une embase de support E ajourée. Le distributeur est représenté sur la figure IA en position de repos et/ou de stockage avec son capot C.The tank R here further comprises a perforated support base E. The distributor is shown in Figure IA in the rest position and / or storage with its cover C.
Le produit remplit tout le volume du réservoir R et remonte dans le volume intérieur de la partie inférieure du corps 1. Le bord inférieur du corps 1 plonge ainsi dans le produit comme représenté sur les figures.The product fills the entire volume of the tank R and goes back into the interior volume of the lower part of the body 1. The lower edge of the body 1 thus plunges into the product as shown in the figures.
Le corps 1 est fermé à sa partie supérieure par un piston qui est au contact du produit. Le piston est constitué d'une bague 2 montée autour de la partie inférieure d'un tube- gicleur central 3.The body 1 is closed at its upper part by a piston which is in contact with the product. The piston consists of a ring 2 mounted around the lower part of a central jet tube 3.
La bague 2 présente une double lèvre radialement extérieure 23 qui est susceptible de coulisser en contact de friction avec la paroi interne du corps 1.The ring 2 has a radially outer double lip 23 which is slidable in frictional contact with the inner wall of the body 1.
La bague 2 est assemblée sur le tube 3 avec un léger jeu axial entre deux butées respectivement basse 31a et haute 32a et en regard d'au moins un orifice d'éjection 30 ménagé transversalement sur le tube 3.The ring 2 is assembled on the tube 3 with a slight axial clearance between two respectively low 31a and high stops 32a and opposite at least one ejection orifice 30 formed transversely on the tube 3.
La bague 2 présente un anneau intérieur cylindro-conique 20 dont les tronçons supérieur 22 et inférieur 21 viennent alternativement, en fonction de la pression transmise par le liquide, en contact étanche avec les butées haute 31a et basse 32a du tube 3 de façon à ouvrir ou à fermer l'orifice d'éjection 30 à la manière d'un clapet comme représenté sur les figures 2 à 5.The ring 2 has a cylindro-conical inner ring 20 whose upper sections 22 and lower 21 alternately, depending on the pressure transmitted by the liquid, in sealing contact with the upper stops 31a and lower 32a of the tube 3 so as to open or closing the ejection port 30 in the manner of a valve as shown in Figures 2 to 5.
L'extrémité inférieure du tube 3 porte une base tronconique 31 à bord plat dont la face supérieure forme la butée basse 31a, en dessous du niveau de l'orifice 30. La base 31 obture l'extrémité inférieure axiale du tube 3.The lower end of the tube 3 carries a frustoconical base 31 with a flat edge whose upper face forms the lower stop 31a, below the level of the orifice 30. The base 31 closes the axial lower end of the tube 3.
Au-dessus du niveau de l'orifice d'éjection 30, la partie inférieure du tube 3 porte un épaulement périphérique 32 dont la face inférieure forme la butée haute 32a de la bague 2. Les tronçons 21, 22 définissent entre eux un angle d'environ 160° à 170° permettant d'assurer un appui à la manière d'un arc-boutement, respectivement, sur la paroi externe du tube 3 pour le tronçon 22 et sur la face supérieure de la base 31 pour le tronçon 21. Cet appui renforcé permet de garantir l'étanchéité du clapet en position de fermeture.Above the level of the ejection orifice 30, the lower part of the tube 3 carries a peripheral shoulder 32 whose lower face forms the upper stop 32a of the ring 2. The sections 21, 22 define between them an angle of approximately 160 ° to 170 ° making it possible to provide support in the manner of an arching, respectively, on the outer wall of the tube 3 for the section 22 and on the upper face of the base 31 for the section 21. This reinforced support ensures the tightness of the valve in the closed position.
L'anneau 20 délimite avec le tube 3, en regard de l'orifice 30, un espace intercalaire de révolution dont les dimensions sont très petites et qui permet la détente et l'échappement du produit sous pression avant son passage par l'orifice 30.The ring 20 delimits with the tube 3, opposite the orifice 30, a spacer space of revolution whose dimensions are very small and which allows the expansion and the escape of the pressurized product before its passage through the orifice 30 .
La face supérieure inclinée de la base tronconique 31 favorise le guidage du tronçon inférieur 21 de l'anneau 20 lors de son déplacement relatif vers le haut à l'ouverture du clapet.The inclined upper face of the frustoconical base 31 promotes guiding of the lower section 21 of the ring 20 during its relative upward movement at the opening of the valve.
La résistance de frottement fb entre l'anneau 20 et la paroi du tube 3 et plus particulièrement entre l'extrémité du tronçon inférieur 21 et la face supérieure de la base 31 est faible (entre 50 et 100g) et, dans tous les cas, inférieure à la résistance de frottement fa entre la double lèvre 23 de la bague 2 et la paroi interne du corps 1 (de l'ordre de 700g).The frictional resistance fb between the ring 20 and the wall of the tube 3 and more particularly between the end of the lower section 21 and the upper face of the base 31 is low (between 50 and 100 g) and, in any case, less than the frictional resistance fa between the double lip 23 of the ring 2 and the inner wall of the body 1 (of the order of 700g).
La résistance de frottement fb- est aussi inférieure à la résistance de frottement fc entre le fond mobile F et la paroi interne du réservoir R (de l'ordre de 3 à 4 kg), en tenant compte des surfaces relatives de la base 31 et du fond F.The frictional resistance fb- is also lower than the frictional resistance fc between the moving bottom F and the inner wall of the tank R (of the order of 3 to 4 kg), taking into account the relative surfaces of the base 31 and from the bottom F.
Le corps 1 est partiellement fermé, en partie haute, par une douille intérieure 10 pourvue d'un collier supérieur 13 de guidage du tube 3 et d'un collier inférieur 12 de plus grand diamètre pour le blocage du piston en position de fermeture de l'orifice d'éjection 30.The body 1 is partially closed, at the top, by an inner sleeve 10 provided with an upper collar 13 for guiding the tube 3 and a lower collar 12 of larger diameter for locking the piston in the closed position. ejection port 30.
La face supérieure de la bague 2 comporte une nervure circulaire 24 délimitant, avec le tronçon supérieur 22 de l'anneau 20, une gorge 25 dans laquelle vient s'engager le collier inférieur 12 de la douille du corps.The upper face of the ring 2 comprises a circular rib 24 delimiting, with the upper portion 22 of the ring 20, a groove 25 in which is engaged the lower collar 12 of the sleeve of the body.
Comme représenté sur les figures IA et IB, l'extrémité supérieure du tube-gicleur 3 est raccordée à un conduit d'échappement 40 ménagé dans un bouton-poussoir 4 pourvu d'une jupe externe 41 et d'un manchon cylindrique interne 42. Le manchon 42 est destiné à coiffer le corps 1 de manière coulissante en emprisonnant un ressort de rappel hélicoïdal 5 monté autour du tube 3 dans l'espace intercalaire.As represented in FIGS. 1A and 1B, the upper end of the nozzle-tube 3 is connected to an exhaust duct 40 formed in a push-button 4 provided with an outer skirt 41 and an internal cylindrical sleeve 42. Sleeve 42 is intended to cap the body 1 slidably by trapping a helical return spring 5 mounted around the tube 3 in the interspace.
La spire inférieure du ressort 5 appui sur la face supérieure de la douille 10 coaxialement au collier supérieur 13.The lower coil of the spring 5 bears on the upper face of the sleeve 10 coaxially with the upper collar 13.
Le corps 1 est solidaire, via une entretoise transversale 11, d'une collerette périphérique 14 de fixation sur le bord supérieur du réservoir R.The body 1 is secured, via a transverse spacer 11, a peripheral collar 14 for fixing to the upper edge of the tank R.
La collerette 14 se prolonge vers le haut par un rebord en saillie 15 susceptible de recevoir, par l'extérieur, le capot C avec d'éventuels moyens d'encliquetage ou de vissage et, par l'intérieur, la jupe 41 du bouton-poussoir 4.The flange 14 is extended upwards by a protruding flange 15 capable of receiving, from the outside, the cover C with any latching or screwing means and, from the inside, the skirt 41 of the button. push 4.
Le fond mobile F comporte une coupelle centrale f dont le profil est complémentaire de celui de la base tronconique 31 du tube 3 et/ou de la partie inférieure du corps 1 de manière à garantir la vidange complète du réservoir.The movable bottom F comprises a central cup f whose profile is complementary to that of the frustoconical base 31 of the tube 3 and / or the lower part of the body 1 so as to ensure complete emptying of the reservoir.
Du fait que le. piston ne trouve, dans sa course descendante à l'intérieur du corps 1, aucune butée d'arrêt, il est prévu pour les besoins du dosage, de ménager un méplat latéral 1 la sur l'entretoise 11. Le bord inférieur de la jupe 41du bouton-poussoir 4 vient alors en butée contre ce méplat ce qui permet, en complément du tarage du ressort 5, de définir les doses de produit à délivrer.Because the. piston does not find, in its descending run inside the body 1, no stop, it is provided for the purpose of dosing, to provide a lateral flat 1 la on the spacer 11. The lower edge of the skirt 41 pushbutton 4 then abuts against this flat which allows, in addition to the calibration of the spring 5, to define the doses of product to be delivered.
Une variante pourrait consister à limiter la course du piston par la mise en butée du bord inférieur du manchon 42 contre l'entretoise 11 ou bien par l'appui contre le bord supérieur du corps de pompe 1 de la paroi supérieure du logement du ressort 5.A variant could be to limit the stroke of the piston by abutment of the lower edge of the sleeve 42 against the spacer 11 or by pressing against the upper edge of the pump body 1 of the upper wall of the spring housing 5 .
Le fonctionnement de la pompe va maintenant être décrit plus en détail à partir des figures 2 à 5.The operation of the pump will now be described in more detail from FIGS. 2 to 5.
Dans la position représentée sur la figure 2, le distributeur est au repos avec le capot C enfermant le bouton-poussoir 4 et la pompe P inactive. Le clapet d'échappement et l'orifice d'éjection 30 sont fermés.In the position shown in Figure 2, the dispenser is at rest with the cover C enclosing the push button 4 and the pump P inactive. The exhaust valve and the ejection port 30 are closed.
Le tronçon 21 de l'anneau 20 du piston est maintenu en appui étanche contre la butée basse 31a grâce aux efforts de réaction du ressort de rappel 5 et à la transmission de ces efforts par le collier inférieur 12.The section 21 of the ring 20 of the piston is kept in sealing engagement against the bottom stop 31a by the reaction forces of the return spring 5 and the transmission of these forces by the lower collar 12.
Dans la position de la figure 3, après enlèvement du capot C, un appui manuel est appliqué sur le bouton-poussoir 4 par un consommateur.In the position of Figure 3, after removal of the cover C, a manual support is applied to the push button 4 by a consumer.
Cet appui entraîne la compression du ressort 5 et la descente du tube 3 au travers du collier 13. La base tronconique 31 s'enfonce alors dans le corps 1 et génère une pression au sein du produit.This support causes the compression of the spring 5 and the descent of the tube 3 through the collar 13. The frustoconical base 31 then sinks into the body 1 and generates a pressure within the product.
Cette pression reste, néanmoins insuffisante, compte tenu du contact de friction (résistance fc) entre le fond mobile F et la paroi du réservoir R, pour entraîner la descente du fond F.This pressure remains, however insufficient, given the frictional contact (resistance fc) between the movable bottom F and the wall of the tank R, to cause the descent of the bottom F.
Conjointement, le contact de friction (résistance fa) entre la double lèvre 23 du piston et la paroi du corps crée une résistance au mouvement qui immobilise la bague 2 pendant une durée, certes très courte, mais suffisante, (compte tenu de la faible résistance fb) pour permettre la séparation du tronçon 21 de la butée basse 31a et, en fonction de la valeur du jeu axial, la mise en butée du tronçon 22 contre la butée haμte 32a.At the same time, the frictional contact (resistance fa) between the double lip 23 of the piston and the wall of the body creates a resistance to movement which immobilizes the ring 2 for a period, albeit very short, but sufficient (given the low resistance fb) to allow the separation of the section 21 of the lower stop 31a and, as a function of the value of the axial clearance, the abutment of the section 22 against the stop hafa 32a.
Le produit s'infiltre alors dans l'espace intercalaire entre l'anneau 20 et le tube 3 et commence à s'échapper par l'orifice 30 comme schématisé par la flèche sur la figure 3. La phase de délivrance est amorcée.The product then infiltrates into the intermediate space between the ring 20 and the tube 3 and begins to escape through the orifice 30 as shown by the arrow in FIG. 3. The delivery phase is initiated.
L'appui sur le bouton-poussoir 4 se poursuit et, du fait de l'augmentation de pression, la résistance de la bague 2 est vaincue.The pressing of the push-button 4 continues and, because of the increase in pressure, the resistance of the ring 2 is overcome.
La distribution du produit s'effectue de manière régulière via le conduit 40. Le tube 3 continue sa descente en entraînant désormais la bague 2 vers le bas jusqu'à ce que la jupe 41 vienne en butée contre le méplat l ia comme représenté sur les figures IB et 4 où la base 31 fait légèrement saillie vers le bas à l'extérieur du corps 1, en plongeant toujours dans le produit.The distribution of the product is carried out regularly via line 40. The tube 3 continues its descent by now driving the ring 2 downwards until the skirt 41 abuts against the flat part 1a as shown in FIGS. 1B and 4 where the base 31 projects slightly downwards at the outside of the body 1, still dipping into the product.
A ce moment, le consommateur sait qu'une dose de produit vient d'être délivrée.At this moment, the consumer knows that a dose of product has just been delivered.
Il relâche alors son appui sur le bouton 4 ce qui provoque immédiatement la disparition de la pression interne et la remontée du tube 3.It then releases its support on the button 4 which immediately causes the disappearance of the internal pressure and the rise of the tube 3.
Toujours en raison de la résistance résultant de la friction, la bague 2 reste immobile au contact de la paroi du corps pendant un temps très court mais suffisant pour que la butée basse 31a revienne au contact du tronçon inférieur 21 de la bague et ferme le clapet, comme représenté sur la figure 5.Still because of the resistance resulting from the friction, the ring 2 remains stationary in contact with the wall of the body for a very short time but sufficient for the lower stop 31a to come into contact with the lower section 21 of the ring and closes the valve as shown in Figure 5.
Le retour à la position de repos s'effectue ensuite sous l'action du ressort de rappel avec le clapet fermé, le tube 3 ramenant la bague 2 vers le haut jusqu'à sa, mise en butée contre Ic collier 12. . • The return to the rest position is then effected under the action of the return spring with the valve closed, the tube 3 bringing the ring 2 upwards to its abutment against the collar 12.. •
Conjointement, le fond mobile F remonte dans le réservoir R de façon à compenser le volume de produit qui a été distribué. At the same time, the mobile bottom F rises in the tank R so as to compensate for the volume of product that has been dispensed.
