Description

POMPE DE FAIBLE CAPACITE A COMPATIBILITE AMELIOREE LOW CAPACITY PUMP WITH IMPROVED COMPATIBILITY

La présente invention concerne une pompe et plus particulièrement une pompe de faible capacité pour la distribution de produits liquides tels que des parfums et des produits cosmétiques ou pharmaceutiques.The present invention relates to a pump and more particularly a low capacity pump for dispensing liquid products such as perfumes and cosmetic or pharmaceutical products.

Les pompes traditionnelles comprennent généralement un corps en matière plastique délimitant une chambre de dosage pourvue à une première extrémité d'un clapet d'admission en produit liquide alimenté à partir d'un réservoir et à une seconde extrémité d'un clapet d'échappement porté par la partie interne d'un tube gicleur mobile axialement en coopérant avec un ressort hélicoïdal.Traditional pumps generally comprise a plastic body delimiting a metering chamber provided at a first end with a valve for admitting liquid product supplied from a tank and at a second end with a worn exhaust valve. by the internal part of an axially movable nozzle tube cooperating with a helical spring.

Cependant, dans de telles pompes le clapet d'admission comporte une bille, réalisée avec des matériaux métalliques, qui est logée à l'intérieur du corps de pompe dans la chambre de dosage tout comme les moyens de rappel constitués généralement d'un ressort lui aussi métalliqueHowever, in such pumps the intake valve includes a ball, made with metallic materials, which is housed inside the pump body in the metering chamber just like the return means generally consisting of a spring itself. also metallic

Par conséquent, le produit qui séjourne même pendant une courte période dans la chambre de dosage est mis en contact avec des éléments métalliques, ce qui présente des risques de modification des propriétés et notamment de la qualité du produit.Consequently, the product which remains even for a short period in the metering chamber is brought into contact with metallic elements, which presents risks of modification of the properties and in particular of the quality of the product.

Par ailleurs, le corps de pompe est réalisé avec une matière plastique opaque pour masquer les éléments métalliques internes. Or le réservoir est le plus souvent constitué d'un flacon en verre ou en matière plastique transparente qui laisse apparaître le corps de la pompe, ce qui n'est pas satisfaisant sur le plan esthétique.Furthermore, the pump body is made with an opaque plastic material to mask the internal metallic elements. However, the reservoir most often consists of a glass or transparent plastic bottle which reveals the body of the pump, which is not satisfactory from an aesthetic point of view.

Par ailleurs, il existe aussi des pompes dans lesquelles les moyens de rappel sont constitués d'un ressort hélicoïdal disposé à l'extérieur de la chambre de dosage. Toutefois, dans ce mode de réalisation, le ressort de rappel est maintenu en légère compression autour de la partie externe du tube gicleur notamment par appui de son extrémité supérieure dans le fond d'une cavité ménagée sur une tête de distribution coiffant l'extrémité dudit tube. Par conséquent, un tel mode de réalisation ne permet pas de séparer la pompe de la tête de distribution en toute sécurité car, dans ce cas, le ressort ne serait plus solidaire d'aucune pièce et serait alors susceptible d'être perdu notamment lors des opérations de stockage ou de transfert automatique.Furthermore, there are also pumps in which the return means consist of a helical spring arranged outside the metering chamber. However, in this embodiment, the return spring is held in slight compression around the external part of the spray tube, in particular by pressing its upper end into the bottom of a cavity formed on a dispensing head covering the end of said tube. Consequently, such an embodiment does not make it possible to separate the pump from the dispensing head safely because, in this In this case, the spring would no longer be attached to any part and would then be liable to be lost, particularly during storage or automatic transfer operations.

En outre, les opérations d'assemblage sont complexes car elles impliquent le montage préalable du ressort.In addition, the assembly operations are complex because they involve the prior mounting of the spring.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante.The present invention aims to solve these technical problems satisfactorily.

Ce but est atteint conformément à l'invention au moyen d'une pompe caractérisée en ce que le clapet d'admission comporte notamment une bille non métallique tandis que la partie externe du tube gicleur est pourvue d'un épaulement latéral contre lequel une première extrémité dudit ressort est en appui de calage.This object is achieved in accordance with the invention by means of a pump characterized in that the intake valve comprises in particular a non-metallic ball while the external part of the spray tube is provided with a lateral shoulder against which a first end said spring is in wedging support.

Selon un mode de réalisation particulier, le corps et la bille sont réalisés avec une matière plastique transparente ou au moins translucide.According to a particular embodiment, the body and the ball are made with a transparent or at least translucent plastic material.

Selon une caractéristique avantageuse, la pompe comporte, en outre, une douille interne emmanchée dans ledit corps pour obturer ladite chambre autour de la partie interne du tube gicleur et dont le fond est destiné à recevoir l'appui de la seconde extrémité du ressort. Selon une autre caractéristique, l'extrémité interne de ladite douille forme une butée pour le clapet d'échappement porté par la partie interne dudit tube.According to an advantageous characteristic, the pump also comprises an internal sleeve fitted in said body to close said chamber around the internal part of the nozzle tube and the bottom of which is intended to receive support from the second end of the spring. According to another characteristic, the internal end of said sleeve forms a stop for the exhaust valve carried by the internal part of said tube.

Selon encore une autre caractéristique, ladite bille est réalisée en verre ou en polypropylène tandis que le corps de pompe est réalisé en polypropylène.According to yet another characteristic, said ball is made of glass or polypropylene while the pump body is made of polypropylene.

Selon une variante particulière, la face de l'épaulement en contact avec la première extrémité du ressort est plane et perpendiculaire à l'axe du tube gicleur.According to a particular variant, the face of the shoulder in contact with the first end of the spring is flat and perpendicular to the axis of the spray tube.

Selon une autre variante, la face de l'épaulement située du côté de l'extrémité externe du tube gicleur est biseautée.According to another variant, the face of the shoulder situated on the side of the external end of the spray tube is bevelled.

De préférence, ledit épaulement est réalisé sur tout le pourtour du tube.Preferably, said shoulder is formed around the entire periphery of the tube.

La pompe de l'invention permet un transfert du produit sans contact avec un quelconque élément métallique, ce qui préserve les qualités du produit et simplifie les opérations de fabrication et de montage tout en offrant un prix de revient économique. Par ailleurs, tous les constituants de la pompe qui sont disposés à l'intérieur du réservoir sont réalisés avec une matière translucide ou transparente à la lumière, ce qui améliore considérablement l'aspect esthétique d'ensemble dans la mesure où la pompe n'apparaît pratiquement plus au sein du produit liquide.The pump of the invention allows a transfer of the product without contact with any metallic element, which preserves the qualities of the product and simplifies the manufacturing and assembly operations while offering an economical cost price. Furthermore, all the components of the pump which are arranged inside the tank are made with a translucent or transparent material to light, which considerably improves the overall aesthetic appearance insofar as the pump does not appear practically no longer within the liquid product.

L'invention sera mieux comprise à la lecture de la description qui va suivre en référence au dessin sur lequel :The invention will be better understood on reading the description which follows with reference to the drawing in which:

- la figure 1 unique représente une vue en coupe d'un mode de réalisation de la pompe de l'invention. La pompe représentée sur la figure 1 comprend un corps 1 réalisé avec une matière plastique transparente ou au moins translucide, par exemple du polypropylène.- Figure 1 is a single sectional view of an embodiment of the pump of the invention. The pump shown in FIG. 1 comprises a body 1 produced with a transparent or at least translucent plastic material, for example polypropylene.

Le corps 1 délimite une chambre de dosage 10 pourvue à une première extrémité d'un clapet d'admission 11 en produit liquide alimenté via un tube plongeur 6 lui aussi translucide à partir d'un réservoir ou d'un flacon (non représenté).The body 1 defines a metering chamber 10 provided at a first end with an inlet valve 11 for liquid product supplied via a dip tube 6 also translucent from a reservoir or a bottle (not shown).

Selon l'invention, le clapet d'admission 11 comporte une bille 5 non métallique, réalisée avec un matériau transparent à la lumière ou au moins translucide tel que du verre ou du propylène. La chambre 10 est pourvue à une seconde extrémité, opposée à la première extrémité, d'un clapet d'échappement 12 porté par la partie interne 2a d'un tube gicleur 2 délimitant un conduit d'éjection axial 20.According to the invention, the inlet valve 11 comprises a non-metallic ball 5, made with a material transparent to light or at least translucent such as glass or propylene. The chamber 10 is provided at a second end, opposite the first end, with an exhaust valve 12 carried by the internal part 2a of a nozzle tube 2 delimiting an axial ejection duct 20.

Le tube gicleur 2 est mobile axialement en coopérant avec un ressort hélicoïdal 3 assurant le rappel en position de fermeture du clapet 12. Le ressort 3 est monté coaxialement autour de la partie externe du tube 2.The spray tube 2 is axially movable by cooperating with a helical spring 3 ensuring the return to the closed position of the valve 12. The spring 3 is mounted coaxially around the external part of the tube 2.

La partie externe du tube 2 est pourvue d'un épaulement latéral 21 contre lequel une première extrémité 31 du ressort 3 est en appui de calage. Le ressort 3 est maintenu en légère compression même dans la position de fermeture du clapet d'échappement 12.The external part of the tube 2 is provided with a lateral shoulder 21 against which a first end 31 of the spring 3 is in wedging support. The spring 3 is held in slight compression even in the closed position of the exhaust valve 12.

L'épaulement 21 est ici réalisé sur tout le pourtour du tube 2 et comporte une face plane 21a de contact avec la spire de l'extrémité 31 du ressort 3. La face 21a est, en outre ici, perpendiculaire à l'axe X du tube 2 et de la pompe. La face 21 b de l'épaulement située du côté de l'extrémité externe 2b du tube 2 est biseautée et forme éventuellement une butée pour le montage d'une tête de distribution ou d'un bouton- poussoir (non représenté) destiné à coiffer le tube 2.The shoulder 21 is here produced around the entire periphery of the tube 2 and has a flat face 21a of contact with the turn of the end 31 of the spring 3. The face 21a is, moreover here, perpendicular to the axis X of the tube 2 and pump. The face 21b of the shoulder situated on the side of the external end 2b of the tube 2 is bevelled and optionally forms a stop for mounting a dispensing head or a push button (not shown) intended to cover the tube 2.

De préférence, la tête de distribution comportera alors soit un alésage cylindrique permettant l'emmanchement en butée sur l'extrémité 2b du tube soit une cavité à profil tronconique destinée à recevoir l'épaulement 21 par assemblage cône sur cône.Preferably, the dispensing head will then comprise either a cylindrical bore allowing the fitting into abutment on the end 2b of the tube or a cavity with a frustoconical profile intended to receive the shoulder 21 by cone-on-cone assembly.

La pompe comporte également une douille interne 4 emmanchée dans le corps 1 pour obturer la chambre 10 autour de la partie interne du tube gicleur 2. La douille 4 est pourvue d'une collerette 41 de support sur le bord externe du corps 1 qui se prolonge à l'intérieur de la chambre 10 par une jupe 42. Dans le mode de réalisation représenté, la jupe 42 est fixée par encliquetage dans la paroi latérale interne de la chambre 10.The pump also includes an internal sleeve 4 fitted into the body 1 to close off the chamber 10 around the internal part of the nozzle tube 2. The sleeve 4 is provided with a support flange 41 on the external edge of the body 1 which extends inside the chamber 10 by a skirt 42. In the embodiment shown, the skirt 42 is fixed by snap-fastening in the internal lateral wall of the chamber 10.

L'extrémité interne de la jupe 42 forme une butée haute pour le clapet d'échappement 12 porté par la partie interne du tube 2. Cette butée correspond à la position de fermeture du clapet 12. Le fond 4a de la douille 4 est destiné à recevoir l'appui de la seconde extrémité 32 du ressort 3. The internal end of the skirt 42 forms a high stop for the exhaust valve 12 carried by the internal part of the tube 2. This stop corresponds to the closed position of the valve 12. The bottom 4a of the sleeve 4 is intended to receive the support of the second end 32 of the spring 3.
