Description

Organe de distribution de produit fluide et distributeur comprenant un tel organe Fluid product distribution member and distributor comprising such a member
La présente invention concerne un organe de distribution de produit fluide destiné à être monté sur une ouverture d'un réservoir de produit fluide. L'invention concerne également un distributeur de produit fluide comprenant un organe de distribution et un réservoir de produit fluide. De tels distributeurs équipés de tels organes sont notamment utilisés dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie. Ils sont destinés à distribuer du produit fluide liquide ou pulvérulent sous la forme d'un jet pulvérisé, d'un filet continu ou encore de grosses gouttes.The present invention relates to a fluid dispenser member intended to be mounted on an opening of a fluid reservoir. The invention also relates to a fluid dispenser comprising a dispensing member and a fluid reservoir. Such dispensers equipped with such organs are used in particular in the fields of perfumery, cosmetics or even pharmacy. They are intended to distribute liquid or powdery fluid in the form of a spray, a continuous stream or even large drops.
En général, de tels organes de distribution comprennent un corps définissant intérieurement une chambre de volume variable, ledit corps définissant une extrémité inférieure, une tige d'actionnement déplaçable axialement en va-et-vient dans ledit corps pour faire varier le volume de ladite chambre, ladite tige comprenant une partie inférieure engagée dans le corps et une partie supérieure définissant une extrémité supérieure, une collerette d'appui périphérique s'étendant radialement vers l'extérieur, ladite collerette comprenant une face inférieure destinée à venir en appui au moins indirect sur un bord de l'ouverture du réservoir de produit fluide, optionnellement un joint de col disposé en contact de la face inférieure de la collerette de manière à être comprimé entre la collerette et le bord de l'ouverture. Le joint de col ne mesure que quelques dixièmes de millimètres d'épaisseur de sorte que la collerette d'appui périphérique détermine la hauteur de l'organe de distribution insérée dans l'ouverture du réservoir ainsi que la hauteur de l'organe de distribution qui fait saillie hors de l'ouverture du réservoir. Pour des raisons esthétiques, mais également fonctionnelles, il est avantageux que la hauteur de l'organe de distribution au dessus de la collerette d'appui ne soit pas trop importante. De ce fait, la plupart des organes de distribution comprennent un corps relativement allongé qui est engagé pour sa majeure partie à l'intérieur de l'ouverture du réservoir. Lorsque l'ouverture est définie par un col relativement allongé, il est possible que l'organe de distribution ne fasse pas saillie en dessous du col à l'intérieur du corps du réservoir. En revanche, lorsque le col est très court comme c'est le cas pour les réservoirs standard, l'organe de distribution, et plus particulièrement le corps, pénètrent à l'intérieur du corps du réservoir de sorte qu'il est possible d'apercevoir le corps à l'intérieur du corps du réservoir lorsque ce dernier est transparent. Ceci n'a pas un effet esthétique très recherché, en particulier dans la parfumerie, ou l'on cherche toujours à masquer au maximum l'organe de distribution.In general, such dispensing members include a body internally defining a chamber of variable volume, said body defining a lower end, an actuating rod movable axially back and forth in said body to vary the volume of said chamber. , said rod comprising a lower part engaged in the body and an upper part defining an upper end, a peripheral support flange extending radially outwards, said flange comprising a lower face intended to come to bear at least indirectly on an edge of the opening of the fluid reservoir, optionally a neck seal disposed in contact with the underside of the collar so as to be compressed between the collar and the edge of the opening. The neck seal is only a few tenths of a millimeter thick so that the peripheral support flange determines the height of the dispensing member inserted into the opening of the reservoir as well as the height of the dispensing member which protrudes out of the tank opening. For aesthetic but also functional reasons, it is advantageous that the height of the dispensing member above the support flange is not too great. Therefore, most of the dispensing members include a relatively elongated body which is engaged for the most part inside the opening of the reservoir. When the opening is defined by a relatively elongated neck, it is possible that the dispensing member does not protrude below the neck at inside the tank body. On the other hand, when the neck is very short, as is the case for standard tanks, the dispensing member, and more particularly the body, penetrates inside the body of the tank so that it is possible to see the body inside the tank body when the tank is transparent. This does not have a much sought after aesthetic effect, in particular in perfumery, where there is always an attempt to mask the dispensing member as much as possible.
Quoi qu'il en soit, la plupart des organes de distribution présentent une hauteur en dessous de la collerette qui est de trois voire quatre fois supérieure à la hauteur au dessus de la collerette.Anyway, most of the dispensing members have a height below the collar which is three or even four times greater than the height above the collar.
Le but de la présente invention est de définir un organe de distribution particulièrement compact qui est compatible avec pratiquement toutes les hauteurs de cols de réservoir, tout en étant particulièrement équilibré.The object of the present invention is to define a particularly compact dispensing member which is compatible with practically all heights of tank necks, while being particularly balanced.
Selon une caractéristique de l'invention, la hauteur axiale HSl séparant axialement la face inférieure de la collerette de l'extrémité supérieure de la tige d'actionnement est sensiblement égale à la hauteur axiale HIl séparant axialement la face inférieure de la collerette de l'extrémité inférieure du corps.According to a characteristic of the invention, the axial height HSl axially separating the lower face of the flange from the upper end of the actuating rod is substantially equal to the axial height HIl axially separating the lower face of the flange from the lower end of the body.
Selon une variante de définition, la hauteur axiale HS2 séparant axialement la face inférieure du joint de l'extrémité supérieure de la tige d'actionnement est sensiblement égale à la hauteur axiale HI2 séparant axialement la face inférieure du joint de l'extrémité inférieure du corps.According to a variant definition, the axial height HS2 axially separating the underside of the seal from the upper end of the actuating rod is substantially equal to the axial height HI2 axially separating the underside of the seal from the lower end of the body .
Etat donné que le joint de col ne présente qu'une épaisseur très réduite, cela revient environ à dire que la collerette est disposée sensiblement à mi- hauteur de l'organe de distribution. Avantageusement, HSl, HS2, HIl et HI2 sont tous de l'ordre de 7 à 9 mm. La hauteur totale de l'organe de distribution est donc de l'ordre de 14 à 18 millimètres, de préférence de 16 à 17 millimètres, ce qui est particulièrement réduit dans le domaine de la cosmétique, de la parfumerie ou de la pharmacie. L'organe de distribution est ainsi pratiquement invisible à l'intérieur d'un col de hauteur moyenne ou même faible. En effet, l'extrémité inférieure du corps ne fait même pas saillie en-dessous du col à l'intérieur du corps du réservoir. Selon un autre aspect de l'invention, l'organe de distribution comprend en outre une tête de distribution montée sur la partie supérieure de la tige et formant un orifice de distribution, ladite tête définissant une extrémité supérieure, la hauteur axiale HS3 séparant axialement la face inférieure de la collerette de l'extrémité supérieure de la tête est légèrement supérieure à la hauteur axiale HI2 séparant axialement la face inférieure de la collerette de l'extrémité inférieure du corps. La tête de distribution est considérée comme un accessoire d'un organe de distribution, étant donné que pour un même organe de distribution, il est possible de monter plusieurs têtes de distribution différentes. Selon l'invention, HS3 est de l'ordre de 9 à 10 mm. Cela revient à dire que pour un joint présentant une épaisseur de l'ordre de 0,5 à 1 millimètre, la hauteur axiale hors tête de distribution HT est de l'ordre de 16 à 17 millimètres, et la hauteur axiale totale avec la tête de distribution peut être de l'ordre de 17 à 19 millimètres.Given that the neck seal has only a very reduced thickness, this amounts approximately to saying that the collar is arranged substantially at mid-height of the dispensing member. Advantageously, HS1, HS2, HIl and HI2 are all of the order of 7 to 9 mm. The total height of the dispensing member is therefore of the order of 14 to 18 millimeters, preferably from 16 to 17 millimeters, which is particularly reduced in the field of cosmetics, perfumery or pharmacy. The dispensing member is thus practically invisible inside a neck of medium or even low height. Indeed, the lower end of the body does not even protrude below the neck inside the body of the tank. According to another aspect of the invention, the dispensing member further comprises a dispensing head mounted on the upper part of the rod and forming a dispensing orifice, said head defining an upper end, the axial height HS3 axially separating the lower face of the collar of the upper end of the head is slightly greater than the axial height HI2 axially separating the lower face of the collar from the lower end of the body. The dispensing head is considered to be an accessory to a dispensing member, since for the same dispensing member, it is possible to mount several different dispensing heads. According to the invention, HS3 is of the order of 9 to 10 mm. This amounts to saying that for a joint having a thickness of the order of 0.5 to 1 millimeter, the axial height excluding the HT distribution head is of the order of 16 to 17 millimeters, and the total axial height with the head distribution can be of the order of 17 to 19 millimeters.
Selon encore un autre aspect de l'invention, l'organe de distribution peut comprendre en outre une frette d'habillage destinée à s'étendre autour du corps à l'extérieur du bord de l'ouverture, ladite frette comprenant une extrémité supérieure, et une tête de distribution montée sur la partie supérieure de la tige et définissant un orifice de distribution latéral, la tête étant déplaçable axialement à l'intérieur de l'extrémité supérieure de la frette. Dans ce cas, la frette peut être montée sur une bague de fixation en prise avec le corps et le réservoir. La frette d'habillage s'étend d'habitude sur toute la hauteur extérieure du col, de sorte que la hauteur sous collerette insérée à l'intérieur n'est même pas visible puisqu'elle ne fait même pas saillie en dessous du col.According to yet another aspect of the invention, the dispensing member may further comprise a covering hoop intended to extend around the body outside the edge of the opening, said hoop comprising an upper end, and a dispensing head mounted on the upper part of the rod and defining a lateral dispensing orifice, the head being displaceable axially inside the upper end of the hoop. In this case, the hoop can be mounted on a fixing ring engaged with the body and the reservoir. The covering band usually extends over the entire outside height of the neck, so that the height under the collar inserted inside is not even visible since it does not even protrude below the neck.
L'invention a également pour objet un distributeur de produit fluide comprenant un réservoir de produit fluide définissant un réservoir avec une ouverture et un organe de distribution tel que défini ci-dessus monté sur l'ouverture du réservoir. Avantageusement, le réservoir comprend un col saillant sensiblement cylindrique délimitant l'ouverture, ledit col définissant une extrémité supérieure libre formant un bord annulaire sur lequel repose la collerette ou le joint et une extrémité inférieure raccordée au corps de réservoir, rextrémité inférieure du corps étant située dans le col de sorte qu'elle ne s'étend pas dans le corps de réservoir. De préférence, la hauteur axiale HC du col est de l'ordre de 7 à 9 mm pour un diamètre interne de l'ordre de 8 mm et un diamètre externe de l'ordre de 13 mm.The invention also relates to a fluid dispenser comprising a fluid reservoir defining a reservoir with an opening and a dispensing member as defined above mounted on the opening of the reservoir. Advantageously, the reservoir comprises a substantially cylindrical projecting neck delimiting the opening, said neck defining a free upper end forming an annular edge on which the flange or seal rests and a lower end connected to the tank body, the lower end of the body being located in the neck so that it does not extend not in the tank body. Preferably, the axial height HC of the neck is of the order of 7 to 9 mm for an internal diameter of the order of 8 mm and an external diameter of the order of 13 mm.
L'invention sera maintenant plus amplement décrite aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will now be described more fully in the accompanying drawings which give by way of nonlimiting example an embodiment of the invention.
Sur les figures : la figure 1 est une vue en coupe transversale verticale à travers un organe de distribution selon l'invention, la figure 2 est une vue en coupe transversale verticale à travers la partie supérieure d'un distributeur de produit fluide incorporant un organe de distribution selon l'invention, et la figure 3 est une vue de face de la partie supérieure de distributeur représentée sur la figure 2.In the figures: FIG. 1 is a vertical cross-section view through a dispensing member according to the invention, FIG. 2 is a vertical cross-section view through the upper part of a fluid dispenser incorporating a member dispenser according to the invention, and FIG. 3 is a front view of the upper part of the dispenser shown in FIG. 2.
L'organe de distribution utilisé pour illustrer la présente invention et représenté sur les figures est une pompe comprenant un corps de pompe 1 de forme générale cylindrique. Le corps 1 est cependant étage de manière à définir une section inférieure 13 est une section supérieure 14. La section supérieure 14 présente un diamètre supérieur à la section inférieure 13. L'extrémité inférieure de la section inférieure 13 définit une entrée 11 qui fait communiquer l'extérieur avec l'intérieur du corps 1 au niveau de la section inférieure 13. Cette entrée 11 est définie par un manchon d'entrée présentant une extrémité inférieure 10 qui forme également l'extrémité la plus inférieure du corps 1.The dispensing member used to illustrate the present invention and shown in the figures is a pump comprising a pump body 1 of generally cylindrical shape. The body 1 is however level so as to define a lower section 13 is an upper section 14. The upper section 14 has a diameter greater than the lower section 13. The lower end of the lower section 13 defines an inlet 11 which communicates the outside with the inside of the body 1 at the lower section 13. This inlet 11 is defined by an inlet sleeve having a lower end 10 which also forms the lower end of the body 1.
L'entrée 11 définit un siège de clapet d'entrée associé à un clapet d'entrée 15 qui peut se déplacer axialement entre une position fermée et une position ouverte.The inlet 11 defines an inlet valve seat associated with an inlet valve 15 which can move axially between a closed position and an open position.
D'autre part, un piston libre 6 présentant une lèvre d'étanchéité externe 61 est engagée à coulissement étanche à l'intérieur de la section supérieure 14, qui définit ainsi un fût de coulissement étanche. Une chambre de pompe 15 est ainsi définie à l'intérieur du corps 1 entre l'entrée 11 sélectivement obturée par le clapet 15 et le piston libre 6. Cette chambre est de volume variable en raison du déplacement du piston 6 à l'intérieur de la section supérieure 14. Le piston libre est monté sur une tige d'actionnement 7 qui pénètre à l'intérieur de la section supérieure 14, mais également dans la section inférieure 15. Le piston libre 6 est monté coulissant sur la tige d'actionnement : le piston et la tige d'actionnement définissent ensemble un clapet de sortie qui fonctionne par coulissement du piston 6 sur une section de la tige d'actionnement 7. Un ressort de précompression permet de solliciter le piston 6 en position de repos fermée. Dès que la pression augmente à l'intérieur de la chambre de pompe 15, le piston libre 6 va se déplacer sur la tige 7 et ainsi ouvrir le clapet de sortie. Il s'agit ici d'une technique conventionnelle pour réaliser un clapet de sortie. La tige d'actionnement 7 définit un canal interne de refoulement à travers lequel le produit fluide mis sous pression dans la chambre de pompe 15 peut s'échapper en passant à travers le clapet de sortie ouvert. La tige d'actionnement 7 définit également une extrémité supérieure 79 qui se présente aussi sous la forme d'un plateau annulaire. La tige d'actionnement 7 est sollicitée en position de repos par un ressort de rappel 76 situé à l'extérieur de la chambre de pompe 15.On the other hand, a free piston 6 having an external sealing lip 61 is engaged in sealed sliding inside the upper section 14, which thus defines a sealed sliding barrel. A pump chamber 15 is thus defined inside the body 1 between the inlet 11 selectively closed by the valve 15 and the free piston 6. This chamber is of variable volume due to the displacement of the piston 6 inside the upper section 14. The free piston is mounted on an actuating rod 7 which penetrates inside the upper section 14, but also in the lower section 15. The free piston 6 is slidably mounted on the actuating rod: the piston and the actuation rod together define an outlet valve which operates by sliding the piston 6 on a section of the actuation rod 7. A precompression spring makes it possible to urge the piston 6 in the closed rest position. As soon as the pressure increases inside the pump chamber 15, the free piston 6 will move on the rod 7 and thus open the outlet valve. This is a conventional technique for making an outlet valve. The actuating rod 7 defines an internal delivery channel through which the fluid product pressurized in the pump chamber 15 can escape by passing through the open outlet valve. The actuating rod 7 also defines an upper end 79 which is also in the form of an annular plate. The actuating rod 7 is biased in the rest position by a return spring 76 located outside of the pump chamber 15.
La pompe comprend également une virole 5 qui définit le point mort haut ou en position de repos du piston 6 et de la tige d'actionnement 7. En d'autres termes, le piston 6 vient en butée contre la virole 5 en l'absence de force exercée sur la tige d'actionnement 7. La virole 5 forme également une collerette d'appui 52 qui s'étend radialement vers l'extérieur. Cette collerette d'appui 52 s'étend autour du corps 1 sensiblement au niveau de la jonction entre les sections inférieure 13 et supérieure 14. La collerette d'appui annulaire 52 comprend une face inférieure 51 en contact avec un joint de col annulaire 2. Le joint comprend une face supérieure 21 en contact de la face inférieure 51 de la collerette et une face inférieure 22 tournée vers le bas. Cette face inférieure 22 du joint 2 est destinée à venir en contact du bord d'extrémité supérieure 911 d'un col 91 d'un réservoir 9. Le col 91 définit ainsi une ouverture 90 permettant d'accéder à un corps de réservoir contenant du produit fluide. Le col 91 peut être relié au corps du réservoir par un épaulement 92 qui s'étend vers l'extérieur comme on peut le voir sur la figure 2. Le col 91 peut également présenter un renfort périphérique extérieur 910 qui fait saillie radialement vers l'extérieur. L'organe de distribution de l'invention est conventionnellement équipé d'une tête de distribution 8 montée sur l'extrémité supérieure de la tige d'actionnement. Cette tête de distribution, qui peut faire office de poussoir, comprend un canal de distribution 82 qui relie le canal de refoulement formé par la tige d'actionnement à un orifice de sortie 81 qui peut être du type gicleur. La tête de distribution peut optionnellement être pourvue d'une coiffe d'habillage 83 qui s'étend tout autour de la tête de distribution. La coiffe d'habillage comprend une surface supérieure d'appui 83 sur laquelle on peut exercer une poussée à l'aide d'un doigt et une jupe périphérique cylindrique 84 qui s'étend vers le bas à partir de la surface d'appui 83.The pump also includes a ferrule 5 which defines the top dead center or in the rest position of the piston 6 and of the actuating rod 7. In other words, the piston 6 abuts against the ferrule 5 in the absence force exerted on the actuating rod 7. The ferrule 5 also forms a support flange 52 which extends radially outwards. This support collar 52 extends around the body 1 substantially at the junction between the lower 13 and upper 14 sections. The annular support collar 52 comprises a lower face 51 in contact with an annular neck seal 2. The seal includes an upper face 21 in contact with the lower face 51 of the flange and a lower face 22 facing downwards. This lower face 22 of the seal 2 is intended to come into contact with the upper end edge 911 of a neck 91 of a reservoir 9. The neck 91 thus defines an opening 90 allowing access to a reservoir body containing fluid product. The neck 91 can be connected to the body of the reservoir by a shoulder 92 which extends towards the outside as can be seen in FIG. 2. The neck 91 can also have an external peripheral reinforcement 910 which projects radially towards the outside. The dispensing member of the invention is conventionally equipped with a dispensing head 8 mounted on the upper end of the actuating rod. This dispensing head, which can act as a pusher, comprises a dispensing channel 82 which connects the delivery channel formed by the actuating rod to an outlet orifice 81 which may be of the nozzle type. The dispensing head can optionally be provided with a covering cap 83 which extends all around the dispensing head. The covering cap comprises an upper bearing surface 83 on which one can exert a thrust using a finger and a cylindrical peripheral skirt 84 which extends downwards from the bearing surface 83 .
D'autre part, l'organe de distribution comprend une bague de fixation 3 qui permet de fixer l'organe de distribution sur le col 91. De manière conventionnelle, la bague de fixation 3 comprend des moyens de réception de l'organe de distribution, par exemple au niveau de sa collerette 52 et comprend d'autre part des pattes de fixation présentant des têtes 31 destinées à venir en prise sous le renfort périphérique 910 du col 91. Il s'agit là d'une forme de réalisation particulière mais d'autres bagues de fixation utilisant d'autres techniques peuvent être utilisées. On peut par exemple imaginer une bague de fixation venant en prise à l'intérieur du col 91. Selon une autre caractéristique, l'organe de distribution comprend une frette d'habillage 4 qui vient habiller la bague de fixation 3. La frette d'habillage 4 comprend une extrémité supérieure 41 formant un rabat vers l'intérieur et une extrémité inférieure libre 42. La frette est sensiblement cylindrique sur toute sa hauteur. Selon l'invention, la tête de distribution 8 peut se déplacer axialement à l'intérieur de la frette d'habillage 4. Même en position de repos, l'extrémité inférieure de la jupe 84 est insérée dans l'extrémité supérieure 41 de la frette 4. Il faut également remarquer que la frette d'habillé 4 s'étend sur la hauteur du col 9, et vient avantageusement en butée avec son extrémité inférieure 42 sur l'épaulement 92. Ainsi, le col 91 n'est plus visible. Selon une caractéristique intéressante de l'invention, la hauteur axialeOn the other hand, the dispensing member comprises a fixing ring 3 which makes it possible to fix the dispensing member on the neck 91. Conventionally, the fixing ring 3 comprises means for receiving the dispensing member , for example at its flange 52 and further comprises fixing lugs having heads 31 intended to come into engagement under the peripheral reinforcement 910 of the neck 91. This is a particular embodiment but other fixing rings using other techniques can be used. One can for example imagine a fixing ring engaging inside the neck 91. According to another characteristic, the dispensing member comprises a covering hoop 4 which comes to dress the fixing ring 3. The hoop covering 4 comprises an upper end 41 forming an inward flap and a free lower end 42. The hoop is substantially cylindrical over its entire height. According to the invention, the dispensing head 8 can move axially inside the covering hoop 4. Even in the rest position, the lower end of the skirt 84 is inserted into the upper end 41 of the hoop 4. It should also be noted that the dressed hoop 4 extends over the height of the neck 9, and advantageously comes into abutment with its lower end 42 on the shoulder 92. Thus, the neck 91 is no longer visible . According to an advantageous characteristic of the invention, the axial height
HSl définie entre la face inférieure 51 de la collerette 52 et l'extrémité supérieure 79 de la tige d'actionnement est sensiblement égale à la hauteur axiale HIl définie entre la face inférieure de la collerette 51 et l'extrémité inférieure 10 du corps 1. Etant donné que le joint de col 2 présente une faible épaisseur de l'ordre de 0,5 à 1 millimètre, on peut également dire que la hauteur axiale HS2 définie entre la face inférieure 22 du joint 2 et l'extrémité supérieure 79 est sensiblement égale à la hauteur HI2 définie entre la face inférieure 22 du joint 2 et l'extrémité inférieure 10 du corps 1. Par conséquent, cela revient à dire que la hauteur de la pompe insérée dans le col 91 est sensiblement égale à la hauteur de la pompe qui fait saillie hors du col lorsque l'on omet la tête de distribution 8 qui n'est qu'un accessoire de la pompe. Et même avec la tête de distribution 8, on peut dire que la hauteur axiale HS3 définie entre la face inférieure 51 de la collerette 52 et la paroi supérieure d'appui 83 de la tête de distribution 8 est sensiblement égale ou légèrement supérieure à la hauteur HIl définie entre la face inférieure de la collerette 52 et l'extrémité inférieure 10 du corps 1. Bien entendu, un tube plongeur 101 peut être monté dans l'entrée 11, comme on peut le voir sur les figures 2 et 3, mais ce tube plongeur 101 ne fait pas partie de la pompe, mais n'en constitue qu'un accessoire.HSl defined between the lower face 51 of the collar 52 and the upper end 79 of the actuating rod is substantially equal to the axial height HIl defined between the underside of the flange 51 and the lower end 10 of the body 1. Since the neck seal 2 has a small thickness of the order from 0.5 to 1 millimeter, it can also be said that the axial height HS2 defined between the lower face 22 of the seal 2 and the upper end 79 is substantially equal to the height HI2 defined between the lower face 22 of the seal 2 and l lower end 10 of the body 1. Consequently, this amounts to saying that the height of the pump inserted in the neck 91 is substantially equal to the height of the pump which projects out of the neck when the dispensing head is omitted 8 which is only an accessory of the pump. And even with the dispensing head 8, it can be said that the axial height HS3 defined between the lower face 51 of the flange 52 and the upper bearing wall 83 of the dispensing head 8 is substantially equal to or slightly greater than the height HIl defined between the lower face of the collar 52 and the lower end 10 of the body 1. Of course, a dip tube 101 can be mounted in the inlet 11, as can be seen in FIGS. 2 and 3, but this dip tube 101 is not part of the pump, but is only an accessory.
En pratique, les hauteurs axiales HSl, HS2, HIl et HI2 peuvent toutes être de l'ordre de 7 à 9 millimètres. Idéalement, HI2 est environ égale à 8,2 millimètres et HIl est égale à 8,8 millimètres, l'épaisseur du joint étant de 0,6 millimètre. On obtient ainsi une pompe tout à fait équilibrée et particulièrement compacte avec la collerette d'appui 52 disposée sensiblement à mi-hauteur de la pompe. On peut également remarquer sur les figures 2 et 3 que l'extrémité inférieure 10 de la pompe est située dans le col sans faire saillie vers le bas l'intérieur du corps du réservoir. Etant donné que la frette d'habillage 4 s'étend jusqu'au niveau de l'épaulement 92, la pompe est ainsi entièrement masquée. On peut ainsi dire qu'elle est invisible. Cette caractéristique peut être mise en œuvre indépendamment du fait que la collerette d'appui est située sensiblement à mi- hauteur de l'organe de distribution. Les dimensions du col peuvent être les suivantes : le diamètre extérieurIn practice, the axial heights HS1, HS2, HIl and HI2 can all be of the order of 7 to 9 millimeters. Ideally, HI2 is approximately equal to 8.2 millimeters and HI is equal to 8.8 millimeters, the thickness of the joint being 0.6 millimeters. A completely balanced and particularly compact pump is thus obtained with the support flange 52 disposed substantially halfway up the pump. It can also be noted in FIGS. 2 and 3 that the lower end 10 of the pump is located in the neck without projecting downwards inside the body of the tank. Since the covering hoop 4 extends to the level of the shoulder 92, the pump is thus entirely masked. We can say that it is invisible. This characteristic can be implemented independently of the fact that the support flange is located substantially mid-height of the dispensing member. The dimensions of the neck can be as follows: the outside diameter
DEC peut être de l'ordre de 13 rnillimètres, le diamètre interne DIC peut être de l'ordre de 8 millimètre avec une hauteur de col de l'ordre de 7 à 9 millimètres tout comme HIl et HI2. Le diamètre externe du corps au niveau de la section inférieure 13 peut être de l'ordre de 6 à 7 millimètres.DEC can be of the order of 13 millimeters, the internal diameter DIC can be of about 8 millimeters with a neck height of about 7 to 9 millimeters just like HIl and HI2. The external diameter of the body at the level of the lower section 13 can be of the order of 6 to 7 millimeters.
On obtient ainsi une pompe avec une hauteur totale hors tête de distribution de 16 à 17 millimètres et de 17 à 19 millimètres avec la tête de distribution.A pump is thus obtained with a total height excluding the dispensing head of 16 to 17 millimeters and of 17 to 19 millimeters with the dispensing head.
Il s'agit là d'une pompe particulièrement compacte avec une hauteur très réduite. Ceci est rendu possible entre autre en raison de la disposition de la section supérieure 14 à l'extérieur du col. En effet, étant donné que le piston 6 coulisse à l'intérieur de cette section, et que cette section peut présenter un diamètre interne indépendant du col, il est possible de réaliser une chambre de pompe 15 avec un volume convenable tout en ayant une hauteur de course très réduite. This is a particularly compact pump with a very reduced height. This is made possible inter alia due to the arrangement of the upper section 14 outside the neck. Indeed, since the piston 6 slides inside this section, and that this section can have an internal diameter independent of the neck, it is possible to produce a pump chamber 15 with a suitable volume while having a height very short stroke.
