Description

DISPOSITIF POUR LE RACCORDEMENT D'UNE POMPE DEVICE FOR CONNECTING A PUMP
La présente invention concerne un dispositif pour le raccordement d'une pompe à une poche souple contenant un produit liquide ou crémeux en vue de constituer un distributeur sans reprise d'air.The present invention relates to a device for connecting a pump to a flexible bag containing a liquid or creamy product in order to constitute a distributor without air intake.
Les distributeurs "airless", c'est-à-dire ceux fonctionnant sans reprise d'air dans le réservoir, comportent une pompe constituée notamment d'un corps pourvu à sa partie inférieure d'un orifice d'admission susceptible de communiquer avec le volume interne d'une poche souple formant le réservoir du produit à distribuer. Cette poche est fixée de manière étanche sur le corps de pompe et est généralement enfermée dans un emballage ou habillage extérieur plus rigide. Cependant, ces distributeurs ne sont pas rechargeables du fait même que la pompe et la poche et parfois même l'habillage extérieur sont assemblés de manière définitive, leur séparation entraînant une rupture irréversible de l'étanchéité."Airless" distributors, that is to say those operating without air intake in the tank, include a pump consisting in particular of a body provided at its lower part with an intake orifice capable of communicating with the internal volume of a flexible pocket forming the reservoir for the product to be dispensed. This pocket is tightly fixed on the pump body and is generally enclosed in a more rigid outer packaging or covering. However, these distributors are not refillable due to the very fact that the pump and the bag and sometimes even the external covering are assembled in a final manner, their separation resulting in an irreversible rupture of the seal.
En outre, l'ensemble pompe/poche ne forme pas une unité intégrale adaptée à tout habillage extérieur. Or, pour des raisons de marketing, la forme et les dimensions de cet habillage sont imposées par les fabricants de produits et sont donc différentes d'un produit à l'autre, ce qui pose des problèmes de raccordement. La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante. Ce but est atteint, selon l'invention, au moyen d'un dispositif pour raccordement du corps d'une pompe sur une poche souple contenant un produit liquide ou crémeux, caractérisé en ce qu'il comprend un manchon cylindrique de fixation étanche de la poche se raccordant dans le haut à un épaulement porteur, d'une part, d'une bague périphérique d'assemblage avec la paroi d'un boîtier extérieur rigide et, d'autre part, d'une douille centrale de support étanche de la pompe.In addition, the pump / bag assembly does not form an integral unit suitable for any exterior covering. However, for marketing reasons, the shape and dimensions of this covering are imposed by the product manufacturers and are therefore different from one product to another, which poses connection problems. The present invention aims to solve these technical problems satisfactorily. This object is achieved, according to the invention, by means of a device for connecting the body of a pump to a flexible bag containing a liquid or creamy product, characterized in that it comprises a cylindrical sleeve for sealingly fixing the pocket connecting at the top to a carrying shoulder, on the one hand, of a peripheral ring for assembly with the wall of a rigid external housing and, on the other hand, of a central socket for the waterproof support of the pump.
Selon une caractéristique avantageuse, la douille centrale comporte une virole interne dans laquelle le corps de pompe est emboîté de manière amovible et fixé par serrage radial. De préférence, ladite virole est disposée à l'intérieur du manchon de fixation de la poche.According to an advantageous characteristic, the central sleeve has an internal ferrule in which the pump body is removably fitted and fixed by radial tightening. Preferably, said ferrule is disposed inside the pocket fixing sleeve.
Selon une autre caractéristique, le dispositif comprend, en outre, une collerette de verrouillage et d'habillage destinée à emprisonner ladite pompe en coiffant la douille centrale. Selon une variante, ladite collerette comporte des moyens de retenue sur la douille centrale.According to another characteristic, the device further comprises a locking and covering collar intended to trap said pump by covering the central bush. According to a variant, said flange comprises means for retaining on the central bush.
Selon une autre variante, ladite collerette est constituée d'une partie basse avec une jupe externe pourvue d'organes d'encliquetage sur la douille centrale et se prolongeant par une partie haute de diamètre restreint pourvue d'une paroi transversale prenant appui axialement sur le corps de la pompe.According to another variant, said flange consists of a lower part with an external skirt provided with snap-fastening members on the central bushing and extended by an upper part of restricted diameter provided with a transverse wall bearing axially on the pump body.
Selon encore une autre variante, ladite collerette comporte une gorge annulaire de calage destinée à recevoir le bord supérieur de la douille.According to yet another variant, said collar comprises an annular wedging groove intended to receive the upper edge of the sleeve.
Selon encore une autre caractéristique, ladite bague périphérique est pourvue d'un orifice d'entrée d'air extérieur.According to yet another characteristic, said peripheral ring is provided with an outside air inlet orifice.
Selon d'autres caractéristiques, ladite bague périphérique est assemblée de manière amovible avec le boîtier extérieur au moyen d'organes d'encliquetage.According to other characteristics, said peripheral ring is removably assembled with the outer casing by means of snap-fastening members.
De préférence, ledit manchon de fixation est adapté à la soudure de la poche. Le dispositif de l'invention permet, le cas échéant, de séparer facilement la pompe de la poche en vue d'effectuer son remplissage ou sa recharge.Preferably, said fixing sleeve is adapted to the welding of the pocket. The device of the invention allows, if necessary, to easily separate the pump from the bag in order to perform its filling or recharging.
En outre, la bague périphérique permet un accostage éventuellement amovible de l'ensemble pompe/poche sur le boîtier d'emballage extérieur dont le profil et la géométrie sont quelconques, ce qui lui confère une grande souplesse d'utilisation et permet l'utilisation de recharges.In addition, the peripheral ring allows optionally removable docking of the pump / bag assembly on the outer packaging box, the profile and geometry of which are arbitrary, which gives it great flexibility of use and allows the use of refills.
Par ailleurs, puisque la pompe n'est pas liée de façon définitive à la poche, il est possible d'assurer de façon simple et rapide l'échange de la pompe en cas de défaut de fonctionnement ou de modification du mode de distribution (par exemple, passage du mode "airless" à un mode atmosphérique). Le dispositif de l'invention permet de fournir un système de distribution sous forme d'un ensemble pompe/poche totalement indépendant et prêt à l'emploi si la poche est préalablement remplie de produit. Ce système peut être emballé rapidement et facilement dans différents boîtiers extérieurs dont les formes sont caractéristiques des marques des produits. Ainsi, il devient possible de commercialiser une recharge constituée du système de distribution précédent, apte et destinée à se fixer sur un boîtier personnalisé vendu, par exemple, séparément.Furthermore, since the pump is not permanently linked to the bag, it is possible to quickly and easily exchange the pump in the event of a malfunction or change in the distribution method (for example example, switching from "airless" mode to an atmospheric mode). The device of the invention makes it possible to provide a distribution system in the form of a completely independent pump / bag assembly and ready for use if the bag is previously filled with product. This system can be quickly and easily packaged in different outer cases whose shapes are characteristic of the brands of the products. Thus, it becomes possible to market a refill made up of the previous distribution system, suitable and intended to be fixed on a personalized box sold, for example, separately.
Le dispositif de l'invention permet aussi le remplissage de la poche par le fond avant introduction dans le boîtier, ce qui autorise des cadences élevées de conditionnement ; la fermeture du fond de la poche étant alors effectuée après remplissage, par soudure directe dans "la veine" du produit. Au surplus, le dispositif de l'invention s'applique aussi bien à des pompes sans évent qu'avec éventThe device of the invention also allows the filling of the bag by the bottom before introduction into the housing, which allows high rates of packaging; closing the bottom of the pocket then being carried out after filling, by direct welding into the "vein" of the product. In addition, the device of the invention applies to both ventless and vented pumps
L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels : La figure 1 représente une vue en coupe d'un premier mode de réalisation du dispositif de l'invention.The invention will be better understood on reading the description which follows, accompanied by the drawings in which: FIG. 1 represents a sectional view of a first embodiment of the device of the invention.
La figure 2 représente une vue en coupe d'un second mode de réalisation du dispositif de l'invention.Figure 2 shows a sectional view of a second embodiment of the device of the invention.
Le dispositif représenté sur les figures est destiné au raccordement d'une pompe P et plus particulièrement d'une pompe "airless" à une poche souple S formant réservoir de produit liquide ou crémeux.The device shown in the figures is intended for connecting a pump P and more particularly an "airless" pump to a flexible bag S forming a reservoir for a liquid or creamy product.
La pompe P est ici sans évent et est équipée d'une tête T de distribution mobile axialement et coiffant le conduit d'échappement E qui fait saillie vers le haut à l'extérieur du corps C de la pompe P. Ce dispositif de raccordement comprend un élément de raccord inférieur 1 constitué d'un manchon cylindrique 10 de fixation étanche de la poche S se rattachant dans le haut à un épaulement 11 porteur, d'une part, d'une bague périphérique 13 d'assemblage avec la paroi d'un emballage extérieur et, d'autre part, d'une douille centrale 12 de support étanche de la pompe P. L'emballage extérieur est, de préférence, formé d'un boîtier rigide B de forme quelconque mais qui doit néanmoins présenter un bord supérieur adapté à une simple liaison mécanique avec la bague 13 de l'élément inférieur 1. Cette liaison est, le cas échéant, assurée de manière amovible au moyen d'organes d'encliquetage ou de vissage appropriés. A cet effet, le bord inférieur de la bague 13 a du côté externe une section en équerre 13a destinée à être fixée (par exemple par collage ou soudage) en appui de calage contre un rétreint b ménagé sur le bord supérieur de la paroi interne du boîtier B.The pump P is here ventless and is equipped with a head T of axially movable distribution and covering the exhaust duct E which projects upwards outside the body C of the pump P. This connection device comprises a lower connector element 1 consisting of a cylindrical sleeve 10 for tightly securing the bag S which is attached at the top to a shoulder 11 carrying, on the one hand, a peripheral ring 13 for assembly with the wall an outer packaging and, on the other hand, a central sleeve 12 for sealing the pump P. The outer packaging is preferably formed by a rigid housing B of any shape but which must nevertheless have an edge upper adapted to a simple mechanical connection with the ring 13 of the lower element 1. This connection is, if necessary, provided in a removable manner by means of appropriate latching or screwing members. To this end, the lower edge of the ring 13 has on the outer side a square section 13a intended to be fixed (for example by gluing or welding) in wedging support against a constriction b formed on the upper edge of the inner wall of the housing B.
Le diamètre de l'ouverture du boîtier B étant plus large que le diamètre du manchon 10 et la poche étant rigidifiée dans sa partie supérieure par ledit manchon, l'introduction et le montage de l'ensemble pompe/poche dans le boîtier B sont rapides et aisés.The diameter of the opening of the housing B being wider than the diameter of the sleeve 10 and the pocket being stiffened in its upper part by said sleeve, the introduction and assembly of the pump / pocket assembly in the housing B are rapid and wealthy.
De préférence, du côté interne la section du bord inférieur de la baguePreferably, on the internal side, the section of the lower edge of the ring
13 est formée en biseau 13b. Si le boîtier est hermétique et, si la fixation de la bague 13 est étanche, il est alors prévu de réaliser au travers de la paroi latérale de la bague 13 un orifice 130 formant évent, destiné à permettre l'entrée d'air extérieur de façon à compenser dans le boîtier B la dépression générée par la déformation progressive de la poche S résultant de l'évacuation du produit.13 is formed in bevel 13b. If the housing is airtight and, if the fixing of the ring 13 is leaktight, provision is made to make through the side wall of the ring 13 an orifice 130 forming a vent, intended to allow the entry of outside air so as to compensate in the housing B for the depression generated by the progressive deformation of the bag S resulting from the evacuation of the product.
La douille centrale 12 comporte une virole interne 14 réalisée de préférence dans le prolongement coaxial du manchon 10 et dans laquelle le corps cylindrique C de la pompe P est emboîté de manière amovible.The central sleeve 12 has an internal ferrule 14 preferably made in the coaxial extension of the sleeve 10 and in which the cylindrical body C of the pump P is removably fitted.
Le serrage radial n'est appliqué que sur la partie supérieure du corps C de la pompe P qui présente le plus grand diamètre. Dans le mode de réalisation de la figure 1, le manchon de fixation 10 de la poche S entoure ici de façon coaxiale la virole 14 et donc la partie inférieure du corps C qui est donc libre, ce qui permet à l'orifice d'admission A situé à l'extrémité inférieure tronconique du corps C d'être au contact direct du produit.Radial tightening is only applied to the upper part of the body C of the pump P which has the largest diameter. In the embodiment of FIG. 1, the fixing sleeve 10 of the pocket S here coaxially surrounds the ferrule 14 and therefore the lower part of the body C which is therefore free, which allows the inlet orifice Located at the frustoconical lower end of the body C to be in direct contact with the product.
Il est aussi possible selon une variante non représentée de désaxer la virole interne 14 par rapport au manchon 10.It is also possible, according to a variant not shown, to offset the internal ferrule 14 relative to the sleeve 10.
Dans le mode de réalisation de la figure 2, le manchon 10 est réalisé dans le prolongement coaxial de la virole 14 mais le serrage radial du corps de pompe n'est toujours assuré qu'au niveau du manchon.In the embodiment of FIG. 2, the sleeve 10 is produced in the coaxial extension of the ferrule 14 but the radial tightening of the pump body is always ensured only at the level of the sleeve.
Dans tous les modes de réalisation, le manchon 10 fait saillie vers le bas au-delà du plan défini par le bord inférieur de la bague 13.In all the embodiments, the sleeve 10 projects downwards beyond the plane defined by the lower edge of the ring 13.
Dans le mode de réalisation représenté sur les figures 1 et 2, le dispositif comporte, en outre, un élément supérieur constitué d'une collerette 2 assurant le verrouillage de la pompe P et l'habillage de la douille 12 de l'élément inférieur 1.In the embodiment shown in Figures 1 and 2, the device further comprises an upper element consisting of a collar 2 ensuring the locking of the pump P and the covering of the sleeve 12 of the lower element 1 .
La partie haute 2a de la collerette 2 se raccorde à la partie basse 2b qui a un diamètre restreint en formant un épaulement 2c. La partie haute 2a porte une paroi transversale 21 qui prend appui axialement sur la partie supérieure du corps C de la pompe P pour l'emprisonner entre la collerette 2 et la douille 12. La paroi transversale 21 est pourvue d'un alésage central 21a destiné à recevoir le conduit d'échappement E de la pompe P.The upper part 2a of the flange 2 is connected to the lower part 2b which has a restricted diameter by forming a shoulder 2c. The upper part 2a carries a transverse wall 21 which bears axially on the upper part of the body C of the pump P to trap it between the collar 2 and the sleeve 12. The transverse wall 21 is provided with a central bore 21a intended to receive the exhaust pipe E of the pump P.
La partie haute 2a comporte également une zone interne 24 de clipsage de la partie supérieure du corps de pompe et une zone externe 25 de guidage axial de la tête T de distribution.The upper part 2a also includes an internal zone 24 for clipping the upper part of the pump body and an external zone 25 for axially guiding the dispensing head T.
La partie basse 2b de la collerette 2 est formée d'une jupe externe 22 pourvue de moyens de retenue sur la douille centrale 12. Ces moyens comprennent des organes d'encliquetage 22a réalisés sur la face interne de la jupe 22 et destinés à coopérer avec des organes complémentaires 12a portés par la face externe de la douille 12. De préférence, la partie basse 2b comporte une gorge annulaire inversée 20 délimitée entre la face interne de la jupe 22 et un flanc cylindrique interne 23 porté par l'épaulement 2c.The lower part 2b of the flange 2 is formed of an external skirt 22 provided with retaining means on the central bush 12. These means comprise snap-fastening members 22a produced on the internal face of the skirt 22 and intended to cooperate with complementary members 12a carried by the external face of the socket 12. Preferably, the lower part 2b comprises an inverted annular groove 20 delimited between the internal face of the skirt 22 and an internal cylindrical flank 23 carried by the shoulder 2c.
La gorge 20 reçoit le bord supérieur de la douille 12 lorsque les organes d'encliquetage 22a de la jupe 22 sont verrouillés sur les organes 12a de façon à assurer le calage de l'élément supérieur 2 sur l'élément inférieur 1.The groove 20 receives the upper edge of the sleeve 12 when the latching members 22a of the skirt 22 are locked on the members 12a so as to secure the upper element 2 on the lower element 1.
Dans cette position, le bord inférieur de la jupe 22 est en butée contre l'épaulement 11.In this position, the lower edge of the skirt 22 is in abutment against the shoulder 11.
Dans le cas ou le dispositif de l'invention est appliqué à une pompe sans évent (comme représentée sur la figure 1), l'étanchéité est assurée principalement par la coopération entre la paroi 21 avec la zone de clipsage 24, d'une part, et la partie supérieure du corps C de pompe P avec son conduit d'échappement E, d'autre part.In the case where the device of the invention is applied to a pump without a vent (as shown in FIG. 1), sealing is ensured mainly by the cooperation between the wall 21 with the clipping zone 24, on the one hand , and the upper part of the pump body C with its exhaust duct E, on the other hand.
Dans le cas où le dispositif de l'invention est appliqué à un corps de pompe pourvu d'un trou d'évent (non représenté) qui serait alors réalisé entre la virole 14 et la zone de clipsage 24, l'étanchéité requise serait alors assurée par un serrage radial de la virole 14 sur le corps C. In the case where the device of the invention is applied to a pump body provided with a vent hole (not shown) which would then be produced between the ferrule 14 and the clipping zone 24, the required seal would then be ensured by a radial tightening of the ferrule 14 on the body C.
