Description

L'invention concerne un flacon de distribution d'un produit fluide, notamment d'un gel ou d'une crème, par exemple d'un produit cosmétique ou d'un produit pharmaceutique.The invention relates to a dispensing bottle of a fluid product, in particular a gel or a cream, for example a cosmetic product or a pharmaceutical product.

On connaît des flacons comprenant un corps définissant un réservoir de conditionnement du produit et une pompe de distribution qui est montée sur ledit corps pour être en communication avec ledit réservoir par l'intermédiaire d'un dispositif d'alimentation en produit. En particulier, la pompe comprend une partie inférieure qui est disposée dans le réservoir pour être en communication avec le produit.Bottles are known comprising a body defining a product conditioning tank and a dispensing pump which is mounted on said body to be in communication with said tank via a product supply device. In particular, the pump comprises a lower part which is arranged in the reservoir to be in communication with the product.

Pour bien préserver le produit de toute dégradation au contact de l'environnement extérieur, le dispositif d'alimentation peut comprendre un piston suiveur qui est monté coulissant dans ledit réservoir pour amener le produit dans la pompe. En effet, dans cette réalisation communément qualifiée de « airless », le réservoir ne contient pas d'air et, en cours d'utilisation, de l'air n'entre pas dans ledit réservoir en compensation du produit distribué.To preserve the product from any degradation in contact with the external environment, the feed device may comprise a follower piston which is slidably mounted in said reservoir to bring the product into the pump. Indeed, in this embodiment commonly referred to as "airless", the tank does not contain air and, in use, air does not enter the tank in compensation for the product dispensed.

On connaît du document EP-0 571 280 , l'utilisation d'une bague de purge qui est interposée entre la partie inférieure de la pompe et le réservoir en permettant la communication entre ladite pompe et le produit conditionné. Ainsi, il est possible de monter la pompe sur le corps en évitant la présence de bulles d'air dans le réservoir qui pourrait conduire à une dégradation du produit et/ou à un désamorçage de la pompe.Document is known EP-0 571 280 , the use of a purge ring which is interposed between the lower part of the pump and the reservoir by allowing communication between said pump and the packaged product. Thus, it is possible to mount the pump on the body by avoiding the presence of air bubbles in the tank which could lead to degradation of the product and / or defusing the pump.

Cette réalisation, si elle donne satisfaction relativement à sa fonction de purge, demeure complexe à mettre en oeuvre, notamment au niveau du montage de la bague sur la pompe.This embodiment, if it gives satisfaction with respect to its purge function, remains complex to implement, especially at the mounting of the ring on the pump.

L'invention vise à perfectionner l'art antérieur en proposant notamment un flacon de distribution dont la fonction de purge est réalisée de façon optimisée.The invention aims to improve the prior art by providing in particular a dispensing bottle whose purge function is performed in an optimized manner.

A cet effet, l'invention propose un flacon de distribution d'un produit fluide, comprenant un corps définissant un réservoir de conditionnement dudit produit et une pompe de distribution dudit produit qui est montée sur ledit corps pour être en communication avec ledit réservoir par l'intermédiaire d'un dispositif d'alimentation en produit, ladite pompe comprenant une partie inférieure qui est disposée dans le réservoir pour être en communication avec le produit, la paroi extérieure de ladite partie inférieure intégrant une membrane de purge, ladite membrane étant agencée pour permettre, lors du montage de la pompe dans le corps, l'évacuation d'air et de produit en excès dans un volume mort et, après ledit montage, la création d'une étanchéité entre l'intérieur dudit réservoir et ledit volume mort.For this purpose, the invention proposes a bottle for dispensing a fluid product, comprising a body defining a container for packaging said product and a dispensing pump for said product which is mounted on said body to be in communication with said tank by means of intermediate of a product supply device, said pump comprising a lower part which is arranged in the reservoir to be in communication with the product, the outer wall of said lower part incorporating a purge membrane, said membrane being arranged to allow, during assembly of the pump in the body, the evacuation of air and excess product in a dead volume and, after said assembly, creating a seal between the interior of said reservoir and said dead volume.

  • les figures 1 sont des vues en coupe longitudinale du flacon de distribution selon un premier mode de réalisation de l'invention, montrant le montage de la pompe dans le corps respectivement après remplissage du réservoir (figure 1a), en cours de montage (figure 1b) et après montage (figure 1 c) ;
  • les figures 2 sont des vues en coupe longitudinale d'un flacon de distribution selon un deuxième mode de réalisation de l'invention, respectivement avant montage de la pompe (figure 2a) et montrant la pompe montée (figure 2b).
Other objects and advantages of the invention will appear in the description which follows, made with reference to the appended figures in which:
  • the figures 1 are views in longitudinal section of the dispensing bottle according to a first embodiment of the invention, showing the mounting of the pump in the body respectively after filling the reservoir ( figure 1a ), being edited ( figure 1b ) and after assembly ( Figure 1 (c) ;
  • the figures 2 are views in longitudinal section of a dispensing bottle according to a second embodiment of the invention, respectively before mounting the pump ( figure 2a ) and showing the pump mounted ( figure 2b ).

Dans la description, les termes de positionnement dans l'espace sont pris en référence à la position du flacon représenté sur les figures.In the description, the spatial positioning terms are taken with reference to the position of the bottle shown in the figures.

En relation avec les figures, on décrit ci-dessous deux modes de réalisation d'un flacon destiné à contenir un produit fluide en vue de sa distribution. Dans des exemples particuliers, le produit peut être un gel ou une crème, par exemple un produit cosmétique ou un produit pharmaceutique.In relation to the figures, two embodiments of a bottle intended to contain a fluid product for distribution purposes are described below. In particular examples, the product may be a gel or a cream, for example a cosmetic product or a pharmaceutical product.

Le flacon comprend un corps 1 définissant un réservoir 2 de conditionnement du produit et une pompe formant système de distribution dudit produit. La pompe est montée sur ledit corps pour être en communication avec ledit réservoir par l'intermédiaire d'un dispositif d'alimentation en produit. Pour ce faire, la pompe comprend une partie inférieure 40 qui est disposée dans le réservoir 2 pour être en communication avec le produit. En particulier, le réservoir 2 peut avoir une contenance comprise entre 1 et 10 ml de sorte à permettre la distribution d'échantillons de produit.The bottle comprises a body 1 defining a reservoir 2 for packaging the product and a pump forming a dispensing system of said product. The pump is mounted on said body to be in communication with said reservoir via a product supply device. To do this, the pump comprises a lower portion 40 which is disposed in the reservoir 2 to be in communication with the product. In particular, the tank 2 may have a capacity of between 1 and 10 ml so as to allow the distribution of product samples.

Selon le premier mode de réalisation (figures 1), la pompe comprend une bague 3 qui est solidaire du corps 1 et un soufflet 4 en matériau élastiquement déformable, notamment en polyoléfine de type polyéthylène ou polypropylène dans laquelle un élastomère de type EPDM, EVA ou polyuréthanne peut être ajouté. Le soufflet 4 comprend une base annulaire 5 montée sur la bague 3, ladite base étant surmontée par une tête 6 élastiquement comprimable de sorte à définir un volume variable à l'intérieur de ladite tête.According to the first embodiment ( figures 1 ), the pump comprises a ring 3 which is integral with the body 1 and a bellows 4 of elastically deformable material, in particular polyolefin of the polyethylene or polypropylene type in which an EPDM, EVA or polyurethane type elastomer may be added. The bellows 4 comprises an annular base 5 mounted on the ring 3, said base being surmounted by a head 6 resiliently compressible so as to define a variable volume within said head.

Sur les figures 1, le soufflet 4 comprend une superposition axiale de plis annulaires formant la tête 6, lesdits plis pouvant passer réversiblement d'une position au repos avec un espacement axial nominal à une position comprimée dans laquelle les plis sont rapprochés afin de réduire le volume intérieur de ladite tête. La tête 6 comprend également une surface supérieure 11 sur laquelle la compression peut être actionnée par appui manuel axial, ladite surface étant reliée à la paroi radiale supérieure du pli supérieur.On the figures 1 , the bellows 4 comprises an axial superposition of annular folds forming the head 6, said folds being able to pass reversibly from a rest position with a nominal axial spacing to a compressed position in which the folds are brought together in order to reduce the internal volume of said head. The head 6 also comprises an upper surface 11 on which the compression can be actuated by axial manual support, said surface being connected to the upper radial wall of the upper fold.

Ainsi, le volume variable est formé par actionnement de la surface supérieure 11 sur une course comprise entre deux cotes axiales respectivement au repos et de fin de course de compression. En outre, la surface supérieure 11 est convexe au repos et concave en fin de course de compression de sorte à pouvoir se retourner pour diminuer le volume de la tête 6 en fin de course de compression. Par ailleurs, la base 5 s'étend axialement vers le bas en étant raccordée à la paroi radiale inférieure du pli inférieur.Thus, the variable volume is formed by actuating the upper surface 11 on a stroke between two axial dimensions respectively at rest and compression end of stroke. In addition, the upper surface 11 is convex at rest and concave at the end of the compression stroke so as to be able to turn to reduce the volume of the head 6 at the end of compression stroke. Furthermore, the base 5 extends axially downwardly by being connected to the lower radial wall of the lower fold.

Dans les modes de réalisation représentés, le corps 1 du flacon est réalisé en matériau rigide, notamment en matériau plastique de type polyéthylène ou polypropylène, pour présenter un tube creux de section circulaire constante entre un fond 14 et un col 30 formant une ouverture supérieure.In the embodiments shown, the body 1 of the bottle is made of rigid material, in particular of plastic material of polyethylene or polypropylene type, to present a hollow tube of constant circular section between a bottom 14 and a neck 30 forming an upper opening.

En outre, le dispositif d'alimentation comprend un piston suiveur 15 qui est monté coulissant dans le réservoir 2 pour amener le produit dans un tube d'alimentation 16.In addition, the feed device comprises a follower piston 15 which is slidably mounted in the reservoir 2 to bring the product into a feed tube 16.

Dans cette réalisation communément qualifiée de « airless », selon le procédé de remplissage, le réservoir 2 peut ne pas contenir d'air. En cours d'utilisation, de l'air n'entre pas dans ledit réservoir en compensation du produit distribué. Le fond 14 du corps 1 présente alors un orifice 17 permettant l'entrée d'air dans le corps 1 en compensation du coulissement du piston 15. Cet orifice peut être recouvert d'une étiquette poreuse, par exemple en papier, afin de limiter les échanges gazeux et donc l'évaporation du produit conditionné.In this embodiment commonly referred to as "airless", according to the filling process, the tank 2 may not contain air. In use, air does not enter the tank in compensation for the dispensed product. The bottom 14 of the body 1 then has an orifice 17 allowing the entry of air into the body 1 in compensation for the sliding of the piston 15. This orifice may be covered with a porous label, for example paper, to limit the gas exchange and thus the evaporation of the packaged product.

Sur les figures 1, le tube 16 est intégré à la bague 3 et comprend la partie inférieure 40 qui est disposée dans le réservoir pour mettre en communication la pompe avec le produit. Par ailleurs, la bague 3 est réalisée en matériau rigide, notamment en matériau plastique de type polyéthylène ou polypropylène, pour être associée, notamment par emmanchement étanche, dans le col 30. Pour ce faire, la bague 3 comprend une portée inférieure 31 de montage qui est serrée dans une gorge 32 formée dans le corps 1, ladite gorge délimitant vers le bas le col 30.On the figures 1 , the tube 16 is integrated in the ring 3 and comprises the lower part 40 which is arranged in the reservoir for communicating the pump with the product. Furthermore, the ring 3 is made of rigid material, in particular of plastic material of polyethylene or polypropylene type, to be associated, in particular by tight fitting, in the neck 30. To do this, the ring 3 comprises a lower bearing surface 31 of mounting which is clamped in a groove 32 formed in the body 1, said groove delimiting down the neck 30.

La bague 3 est pourvue d'un canal 19 d'amenée du produit vers l'intérieur du soufflet 4, la partie amont dudit canal étant formée dans le tube d'alimentation 16 et sa partie aval étant formée dans une cheminée supérieure 20 de la bague 3, ladite cheminée surmontant ledit tube pour être disposée à l'intérieur du soufflet 4. En particulier, la partie inférieure 40 permet la communication entre le canal d'amenée 19 et le produit.The ring 3 is provided with a channel 19 for feeding the product into the interior of the bellows 4, the upstream portion of said channel being formed in the feed tube 16 and its downstream part being formed in an upper chimney 20 of the ring 3, said chimney surmounting said tube to be disposed inside the bellows 4. In particular, the lower portion 40 allows communication between the supply channel 19 and the product.

Le canal d'amenée 19 est équipé d'un clapet d'admission qui, sur les figures, comprend une bille 21 logée dans un siège formé dans la partie inférieure de la cheminée 20. Plus précisément, la cheminée 20 présente une partie inférieure tronconique qui est reliée à l'extrémité supérieure du tube 16, le siège étant formé dans ladite partie tronconique qui comprend en outre des pattes de rétention de la bille 21. Ce montage permet à la bille 21 de se déplacer depuis une position basse de fermeture du canal 19 lors de la compression du soufflet 4, vers une position haute d'admission du produit dans le soufflet 4 lors de la décompression de celui-ci.The supply channel 19 is equipped with an intake valve which, in the figures, comprises a ball 21 housed in a seat formed in the lower part of the chimney 20. More specifically, the chimney 20 has a frustoconical lower part. which is connected to the upper end of the tube 16, the seat being formed in said frustoconical portion which further comprises retention lugs of the ball 21. This assembly allows the ball 21 to move from a low closing position of the channel 19 during the compression of the bellows 4, to an upper position of admission of the product in the bellows 4 during the decompression thereof.

La pompe comprend en outre un clapet d'échappement du produit depuis l'intérieur du soufflet 4 en vue de sa distribution. Le clapet d'échappement est interposé entre la bague 3 et le soufflet 4 de sorte à délimiter une chambre annulaire supérieure de dosage 22 dont le volume est variable et une chambre annulaire inférieure de distribution 23 dont le volume est sensiblement constant, ladite chambre de distribution étant formée à l'intérieur de la base 5 pour être en communication avec un orifice de distribution 24 formé dans ladite base.The pump further comprises an exhaust valve of the product from the inside of the bellows 4 for distribution. The exhaust valve is interposed between the ring 3 and the bellows 4 so as to delimit an upper annular dosing chamber 22 whose volume is variable and a lower annular distribution chamber 23 whose volume is substantially constant, said distribution chamber being formed inside the base 5 to be in communication with a dispensing orifice 24 formed in said base.

Dans le mode de réalisation représenté, la base comprend une partie inférieure qui est disposée dans le col 30 et une partie supérieure dans laquelle la chambre 23 et l'orifice 24 de distribution sont formés. En outre, la base 5 est disposée autour de la bague 3 qui comprend des anneaux d'accrochage 3a, 3b agencés pour assurer un serrage radial de la partie inférieure de la base 5 dans le col 30. Sur les figures, deux anneaux 3a, 3b sont espacés axialement pour s'incruster dans la partie inférieure de sorte à assurer le serrage dans deux plans radiaux.In the embodiment shown, the base comprises a lower portion which is disposed in the neck 30 and an upper portion in which the chamber 23 and the dispensing orifice 24 are formed. In addition, the base 5 is arranged around the ring 3 which comprises fastening rings 3a, 3b arranged to ensure a radial clamping of the lower part of the base 5 in the neck 30. In the figures, two rings 3a, 3b are spaced axially to become embedded in the lower part so as to ensure the clamping in two radial planes.

Le flacon de distribution comprend également un capot 28 en matériau rigide qui est destiné à recouvrir le soufflet 4 entre les distributions, ledit capot en position de recouvrement étant agencé pour entourer avec interférence la partie supérieure de la base 5, la bague 3 comprenant un anneau de maintien 3c de ladite partie supérieure. Cette réalisation, en permettant au soufflet 4 d'exercer une force de réaction radiale au serrage du capot 28, vise à améliorer la fixation et l'étanchéité du soufflet 4 dans le corps, notamment lors du retrait du capot 28.The dispensing bottle also comprises a cover 28 of rigid material which is intended to cover the bellows 4 between the distributions, said cap in the overlap position being arranged to surround with interference the upper part of the base 5, the ring 3 comprising a ring holding 3c of said upper part. This embodiment, by allowing the bellows 4 to exert a radial reaction force when the cover 28 is tightened, aims at improving the fastening and the sealing of the bellows 4 in the body, in particular during the removal of the hood 28.

Dans le premier mode de réalisation représenté, la partie inférieure de la cheminée 20, et donc le clapet d'admission 21, est disposée dans la chambre de dosage 22 de sorte que ladite cheminée s'étende axialement dans ladite chambre de dosage. Ainsi, en fin de course de compression, la surface supérieure 11 est proche voire en contact du clapet d'admission 21 de sorte à optimiser le taux de compression et donc l'aspiration conférés.In the first embodiment shown, the lower part of the chimney 20, and therefore the intake valve 21, is disposed in the metering chamber 22 so that said chimney extends axially in said metering chamber. Thus, at the end of the compression stroke, the upper surface 11 is close or in contact with the inlet valve 21 so as to optimize the compression ratio and thus the suction conferred.

Selon une réalisation, cette optimisation est obtenue avec une cheminée 20 qui s'étend axialement dans la chambre de dosage 22 jusqu'à une cote comprise entre 50% et 100% de la cote axiale de fin de course de la surface supérieure 11.According to one embodiment, this optimization is obtained with a stack 20 which extends axially in the metering chamber 22 up to a dimension of between 50% and 100% of the axial end-of-travel dimension of the upper surface 11.

Par ailleurs, comme représenté sur les figures 1, la paroi extérieure de la cheminée 20 est disposée dans la chambre de dosage 22 avec un jeu radial qui est agencé pour permettre un guidage axial de la tête 6 lors de sa compression. En outre, la paroi extérieure de la cheminée 20 présente des nervures longitudinales 20b qui forment moyens de guidage axial de la tête 6. En effet, la combinaison du jeu et des nervures 20b permet de limiter la mise en travers de la tête 6 lors la compression en favorisant le maintien en ligne de l'affaissement des plis.Moreover, as represented on figures 1 , the outer wall of the stack 20 is disposed in the metering chamber 22 with a radial clearance which is arranged to allow axial guidance of the head 6 during its compression. In addition, the outer wall of the chimney 20 has longitudinal ribs 20b which form axial guiding means of the head 6. Indeed, the combination of the game and the ribs 20b makes it possible to limit the skewing of the head 6 during the compression by promoting the maintenance in line of the collapse of the folds.

Le clapet d'échappement représenté comprend une membrane annulaire 26 présentant une base venue de matière avec la bague et une extrémité libre. Plus précisément, la membrane 26 s'étend sensiblement radialement autour de la paroi extérieure du tube 16 en étant légèrement inclinée vers le haut. Par conséquent, la paroi extérieure du tube 16 comprend successivement la membrane d'échappement 26, l'anneau de maintien 3c et les anneaux d'accrochage 3b, 3a, le clapet d'admission 21 étant disposé au dessus de ladite membrane d'échappement.The illustrated exhaust valve comprises an annular membrane 26 having a base integral with the ring and a free end. More specifically, the membrane 26 extends substantially radially around the outer wall of the tube 16 while being slightly inclined upwards. Therefore, the outer wall of the tube 16 comprises successively the exhaust membrane 26, the retaining ring 3c and the attachment rings 3b, 3a, the intake valve 21 being disposed above said exhaust membrane .

La membrane 26 est agencée pour être déplaçable en flexion par compression du produit dans la chambre de dosage 22 entre une position de repos dans laquelle l'extrémité libre est en appui étanche sur le soufflet 4 et une position contrainte dans laquelle l'extrémité libre est disposée à distance dudit soufflet pour permettre le passage du produit sous pression depuis la chambre de dosage 22 vers la chambre de distribution 23.The membrane 26 is arranged to be displaceable in bending by compression of the product in the metering chamber 22 between a rest position in which the free end is in sealing engagement with the bellows 4 and a constrained position in which the free end is arranged at a distance from said bellows to allow the passage of the pressurized product from the metering chamber 22 to the distribution chamber 23.

En particulier, l'extrémité libre de la membrane 26 en position de repos est en appui étanche sur la face inférieure de la paroi radiale inférieure 8 du pli inférieur. La fonction du clapet d'admission est ainsi obtenue de façon satisfaisante en ce que, lors de la compression du soufflet 4, ladite paroi est sensiblement fixe en position relativement à la bague 3.In particular, the free end of the membrane 26 in the rest position is in sealing engagement on the lower face of the lower radial wall 8 of the lower fold. The function of the intake valve is thus satisfactorily obtained in that, during compression of the bellows 4, said wall is substantially fixed in position relative to the ring 3.

La pompe comprend en outre une membrane de purge 34 qui est intégrée sur la paroi extérieure de la partie inférieure 40 du tube 16, en dessous de la portée de montage 31. La membrane de purge 34 est agencée pour permettre, lors du montage de la pompe dans le corps 1, l'évacuation d'air et de produit en excès dans un volume mort 35 et, après ledit montage, la création d'une étanchéité entre l'intérieur du réservoir 2 et ledit volume mort.The pump further comprises a purge membrane 34 which is integrated on the outer wall of the lower part 40 of the tube 16, below the mounting surface 31. The purge membrane 34 is arranged to allow, during assembly of the pump in the body 1, the discharge of air and excess product in a dead volume 35 and, after said assembly, the creation of a seal between the inside of the tank 2 and said dead volume.

En particulier, le volume mort 35 est formé sous le col 30 du corps 1 en étant délimité axialement de part et d'autre par la portée de montage 31 et par la membrane de purge 34.In particular, the dead volume 35 is formed under the neck 30 of the body 1 being delimited axially on both sides by the mounting surface 31 and by the purge membrane 34.

En relation avec les figures 1, on décrit le montage de la pompe dans lequel, après remplissage du réservoir 2 avec le produit (figure 1a), l'ensemble bague 3 / soufflet 6 / capot 28 / bille 21 est introduit dans le col 30 du corps 1. Sur la figure 1b, on voit que la membrane de purge 34 vient en étanchéité sur une portée intérieure du corps, ladite portée comprenant un manchon axial qui est surmonté par une partie divergente 36 de raccordement avec la gorge de montage 32. Il se forme alors une pression d'air sous la membrane 34, ce qui entraîne son fléchissement vers le haut et donc une fuite d'air vers le volume mort 35.In relation to figures 1 , the assembly of the pump is described in which, after filling of the tank 2 with the product ( figure 1a ), the assembly ring 3 / bellows 6 / cover 28 / ball 21 is introduced into the neck 30 of the body 1. On the figure 1b it can be seen that the purge membrane 34 seals on an inner bearing surface of the body, said bearing comprising an axial sleeve which is surmounted by a diverging portion 36 of connection with the mounting groove 32. air under the membrane 34, which causes it to bend upwards and therefore an air leak towards the dead volume 35.

Dans le mode de réalisation représenté, des passages d'évent longitudinaux 37 sont formés autour de la partie inférieure de la base 5 de sorte, lors du montage de la pompe, à permettre l'échappement de l'air depuis le volume mort 35 vers l'extérieur.In the embodiment shown, longitudinal vent passages 37 are formed around the lower part of the base 5 so, when mounting the pump, to allow the escape of air from the dead volume 35 to outside.

Lorsqu'on continue à appuyer sur l'ensemble pour l'enfoncer complètement dans le col 30, une fois que l'air est complètement évacué, une petite quantité de produit peut déborder au dessus de la membrane 34 et rester contenue dans le volume mort 35 tandis que le montage de la portée 31 dans la gorge 32 assure le maintien et l'étanchéité de la pompe dans le corps 1 (figure 1c). L'air contenu dans le volume mort 35 n'est donc plus en contact avec le produit conditionné dans le réservoir 2, de sorte que le flacon est purgé de l'air lors du remplissage et pourra distribuer sans laisser l'air rentrer en contact avec le produit.When continuing to press the assembly to drive it completely into the neck 30, once the air is completely removed, a small amount of product may overflow the membrane 34 and remain contained in the dead volume 35 while the mounting of the bearing 31 in the groove 32 ensures the maintenance and sealing of the pump in the body 1 ( figure 1c ). The air contained in the dead volume 35 is therefore no longer in contact with the product packaged in the tank 2, so that the bottle is purged of air during filling and can be dispensed without allowing air to come into contact. with the product.

En relation avec les figures 2, on décrit un deuxième mode de réalisation dans lequel la pompe comprend un corps 50 de pompe monté dans le corps 1, ledit corps de pompe intégrant la partie inférieure 40. Comme dans le premier mode de réalisation, la paroi extérieure de la partie inférieure 40 intègre une membrane de purge 34 dont la géométrie et le fonctionnement sont analogues à ceux décrits ci-dessus.In relation to figures 2 a second embodiment in which the pump comprises a pump body 50 mounted in the body 1, said pump body incorporating the lower part 40. As in the first embodiment, the outer wall of the lower part 40 integrates a purge membrane 34 whose geometry and operation are similar to those described above.

Le corps 50 de pompe est monté sur le corps 1 par l'intermédiaire d'un manchon 51 de montage, ledit manchon comprenant une portée 51a de montage étanche sur une portée 1 a complémentaire du corps 1, le volume mort 35 étant fermé par le montage desdites portées.The pump body 50 is mounted on the body 1 by means of a mounting sleeve 51, said sleeve comprising a sealing surface 51a mounted on a surface 1 complementary to the body 1, the dead volume 35 being closed by the mounting said litters.

En outre, au moins l'une des portées 51a, 1a peut comprendre un passage d'évent qui est agencé pour, lors du montage de la pompe, permettre l'échappement d'air vers l'extérieur du réservoir 2. En particulier, le passage d'évent peut être réalisé sous la forme d'une zone rainurée formée sur l'une des portées 51 a, 1a, ladite zone rainurée étant délimitée par une zone lisse sur laquelle l'étanchéité est réalisée en fin de montage par coulissement de la portée 51 a sur la portée 1 a.In addition, at least one of the bearing surfaces 51a, 1a may comprise a vent passage which is arranged to, during assembly of the pump, allow the escape of air towards the outside of the tank 2. In particular, the vent passage may be in the form of a grooved zone formed on one of the bearing surfaces 51a, 1a, said grooved zone being delimited by a smooth zone on which sealing is carried out at the end of assembly by sliding the bearing 51 a on the bearing 1 a.

La pompe représentée est de structure classique en comprenant

  • - un gicleur 52 solidaire d'un bouton poussoir 53 pour être actionné en translation dans le corps 50 de pompe, ledit gicleur comprenant un chemin de distribution 54 comprenant au moins un orifice amont et un canal dont l'extrémité aval est en communication avec un orifice de distribution 55 ;
  • - un moyen de rappel élastique 56 de la translation dudit gicleur dans ledit corps ;
  • - un piston 57 monté en contact frottant contre la surface interne du corps 50 de sorte à délimiter une chambre de dosage 22 qui est en communication avec un canal d'amenée 19 formé dans le tube 16, ledit canal étant équipé d'un clapet d'admission (une bille 21 sur les figures), ledit piston étant agencé pour présenter un état d'obturation des orifices amont et un état de mise en communication desdits orifices amont avec la chambre de dosage 22.
The pump shown is of conventional structure comprising
  • a nozzle 52 integral with a push button 53 to be actuated in translation in the pump body 50, said nozzle comprising a distribution path 54 comprising at least one upstream orifice and a channel whose downstream end is in communication with a dispensing orifice 55;
  • an elastic return means 56 for translating said nozzle into said body;
  • a piston 57 mounted in rubbing contact against the internal surface of the body 50 so as to define a metering chamber 22 which is in communication with a supply channel 19 formed in the tube 16, said channel being equipped with a valve admission (a ball 21 in the figures), said piston being arranged to present a state of closure of the upstream orifices and a state of communication of said upstream orifices with the metering chamber 22.

En outre, le corps 1 comprend un col 30 dans lequel la partie inférieure 40 est montée de façon étanche pour former le volume mort 35 au dessus de la membrane de purge 34, ledit col étant associé au corps 1 pour former le réservoir 2.In addition, the body 1 comprises a neck 30 in which the lower portion 40 is sealingly mounted to form the dead volume 35 above the purge membrane 34, said neck being associated with the body 1 to form the reservoir 2.

Par ailleurs, comme dans le mode de réalisation précédemment décrit, la membrane de purge 34 présente une base venue de matière avec la paroi extérieure de la partie inférieure 40 et une extrémité libre 34a formant une lèvre d'étanchéité qui est en appui sur une portée intérieure du corps 1, ledit appui étant agencé pour permette l'évacuation lors du montage par coulissement de ladite lèvre sur ladite portée et pour assurer l'étanchéité après montage.Furthermore, as in the embodiment previously described, the purge membrane 34 has a base formed integrally with the outer wall of the lower part 40 and a free end 34a forming a sealing lip which bears on a bearing internal body 1, said support being arranged to allow evacuation during mounting by sliding of said lip on said scope and to seal after assembly.

Sur les figures 2, la portée intérieure comprend un manchon axial 58 qui est délimité vers le bas par un épaulement annulaire 59, ledit épaulement étant agencé pour mettre en contrainte l'extrémité libre 34a après montage. Ainsi, on peut conserver une membrane 34 sensiblement radiale avant montage de sorte à faciliter son moulage conjoint avec la partie inférieure 40, et induire une légère flexion vers le haut de ladite membrane pour améliorer l'étanchéité conférée après montage. En outre, cette géométrie de portée intérieure pourrait également être mise en oeuvre en relation avec le premier mode de réalisation.On the figures 2 , the inner bearing includes an axial sleeve 58 which is delimited downwards by an annular shoulder 59, said shoulder being arranged to constrain the free end 34a after assembly. Thus, it is possible to maintain a substantially radial diaphragm 34 before mounting so as to facilitate its joint molding with the lower part 40, and to induce a slight upward bending of said membrane to improve the sealing imparted after assembly. In addition, this interior bearing geometry could also be implemented in relation to the first embodiment.
