Description

DISPOSITIF DE CONDITIONNEMENT ET DE DISTRIBUTION DE PRODUITS FLUIDES, LIQUIDES OU PATEUX  DEVICE FOR PACKAGING AND DISPENSING FLUID, LIQUID OR PASTY PRODUCTS
La présente invention concerne un dispositif de conditionnement et de distribution de produits fluides, liquides ou pâteux, et plus particulièrement un dispositif à embout prolongateur sans reprise d'air appelé couramment "airless". The present invention relates to a device for packaging and dispensing fluid products, liquid or pasty, and more particularly an extension nozzle device without air intake commonly called "airless".
Dans certains domaines d'utilisation de flacons distributeurs de produits fluides, notamment celui des produits pharmaceutiques et cosmétiques, il est indispensable d'assurer le conditionnement et la distribution de produits contenus dans le flacon à l'abri de l'air. Les dispositifs connus comportent généralement un récipient à coque rigide dans lequel se déplace un piston repoussant le produit vers l'orifice d'admission dans la chambre de dosage et l'isolant de l'air qui pénètre au-dessous du piston.  In certain areas of use of fluid dispensing bottles, in particular that of pharmaceutical and cosmetic products, it is essential to ensure the packaging and distribution of products contained in the bottle in the absence of air. Known devices generally include a rigid-shell vessel in which a piston pushing the product toward the inlet into the metering chamber and the air insulation penetrating below the piston moves.
On connaît aussi des dispositifs à récipient rigide dans lequel est placée une poche souple déformable qui se rétracte au fur et à mesure que le produit en est extrait. Le produit restant dans la poche est maintenu à l'abri de l'air, tandis que l'expulsion du produit hors de la poche peut être obtenue au moyen d'une pompe sans reprise d'air, ou "airless", ou sous la pression d'un gaz propulseur agissant sur la paroi de la poche, dans le flacon.  Also known are rigid container devices in which is placed a deformable flexible pouch which retracts as the product is extracted. The product remaining in the pocket is kept out of the air, while the expulsion of the product out of the pocket can be obtained by means of a pump without air intake, or "airless", or under the pressure of a propellant gas acting on the wall of the pocket, in the bottle.
Par ailleurs, le principe de fonctionnement des pompes doseuses pour la distribution de produits fluides, liquides ou pâteux, est bien connu. Une pompe doseuse manuelle est généralement montée sur un flacon contenant le produit à distribuer et elle est constituée d'une chambre doseuse présentant un volume déterminé, d'un piston susceptible de se déplacer dans la chambre sous l'action d'un poussoir, et d'au moins deux clapets. Le clapet inférieur, ou clapet d'admission, situé à l'entrée de la chambre et contrôlant la communication avec l'intérieur du flacon, est fermé lorsque le poussoir est enfoncé tandis que le clapet supérieur, à la sortie de la chambre, est ouvert, laissant passer le produit expulsé de la chambre par le déplacement du piston, puis, lorsque le poussoir est relâché, le piston remonte dans la chambre sous l'action d'un ressort, le clapet supérieur se referme tandis que le clapet inférieur s'ouvre, permettant le remplissage de la chambre en vue d'une nouvelle distribution d'une dose de produit. Moreover, the operating principle of dosing pumps for dispensing fluid, liquid or pasty products is well known. A manual metering pump is generally mounted on a bottle containing the product to be dispensed and consists of a metering chamber having a determined volume, a piston capable of moving in the chamber under the action of a pusher, and at least two valves. The lower flap, or intake flap, located at the entrance to the chamber and controlling communication with the inside of the bottle, is closed when the pusher is depressed while the upper valve, at the exit of the chamber, is open, allowing the product expelled from the chamber by the movement of the piston, then, when the pusher is released , the piston rises in the chamber under the action of a spring, the upper valve closes while the lower valve opens, allowing the filling of the chamber for a new distribution of a dose of product.
Un dispositif de conditionnement et de distribution de produits fluides, liquides ou pâteux, pourvu d'un embout prolongateur est décrit dans le document de brevet FR 2 743 544. Cet embout spécifique, éventuellement pourvu d'un gicleur, est disposé à la sortie de la pompe, de manière à prolonger la buse de sortie du produit.  A device for packaging and dispensing fluid, liquid or pasty products, provided with an extension nozzle is described in patent document FR 2 743 544. This specific nozzle, possibly provided with a nozzle, is disposed at the exit of the pump, so as to extend the outlet nozzle of the product.
Un tel embout prolongateur peut être monté sur un dispositif de distribution de produit peu sensible à la dégradation et distribué en quantités relativement peu précises, mais il n'est pas adapté à un produit susceptible de se dégrader au contact de l'air et destiné à être distribué en doses unitaires constantes.  Such an extension nozzle can be mounted on a product dispensing device that is not very sensitive to degradation and distributed in relatively inaccurate quantities, but it is not suitable for a product liable to degrade in contact with the air and intended to be distributed in constant unit doses.
En effet, un tel prolongateur pose des problèmes techniques de risque de contamination du produit contenu dans l'embout prolongateur et de perte de produit dans l'embout prolongateur par écoulement, évaporation ou capillarité, entre deux utilisations, entraînant le risque de fausser la dose délivrée par la pompe.  Indeed, such an extension poses technical problems of risk of contamination of the product contained in the extension tip and loss of product in the extension tip by flow, evaporation or capillarity between two uses, leading to the risk of distorting the dose delivered by the pump.
Une autre difficulté rencontrée dans le domaine des produits pharmaceutiques et hygiéniques résulte de la nécessité de délivrer le produit dans une zone peu accessible, comme par exemple le conduit auditif de l'oreille, la zone sublinguale ou les parties inférieures du corps.  Another difficulty encountered in the field of pharmaceutical and hygienic products results from the need to deliver the product in an inaccessible area, such as the auditory canal of the ear, the sublingual area or the lower parts of the body.
Un dispositif de conditionnement et de distribution de produits fluides pourvu d'un embout prolongateur est également décrit dans le document de brevet FR 2 860 768. Ce distributeur de produits fluides est pourvu d'un noyau, connecté par une première extrémité à une buse associée à une pompe montée sur un flacon contenant le produit à distribuer et comportant à sa seconde extrémité distale un orifice d'évacuation . A device for packaging and dispensing fluid products provided with an extension nozzle is also described in patent document FR 2 860 768. This dispenser of fluid products is provided with a core, connected at one end to a nozzle associated with a pump mounted on a bottle containing the product to be dispensed and having at its second distal end a discharge orifice.
Ce noyau porte une enveloppe dont une première extrémité est disposée sur l'orifice d'évacuation . Cette enveloppe est destinée à s'ouvrir à sa seconde extrémité distale portant une fente auto-jointante, sous la pression du produit lors de l'actionnement de ladite pompe.  This core carries an envelope of which a first end is disposed on the discharge orifice. This envelope is intended to open at its second distal end bearing a self-sealing slot under the pressure of the product during the actuation of said pump.
L'enveloppe comporte une partie externe tubulaire, déformable élastiquement en flexion longitudinale à la manière d'une spatule souple, dont une première extrémité est disposée sur l'orifice d'évacuation et dont la section externe de forme affinée di minue régulièrement vers sa seconde extrémité distale, au moins sur une partie de sa longueur  The casing comprises a tubular outer portion, elastically deformable in longitudinal flexion in the manner of a flexible spatula, a first end of which is disposed on the outlet orifice and whose outer section of refined shape di minues regularly towards its second distal end, at least for part of its length
L'utilisation d'une simple fente auto-jointante entraîne une obturation insuffisante qui est préjudiciable à l'utilisation de ce dispositif pour des produits très sensibles à la dégradation au contact de l'air et d'obtenir une distribution en doses unitaires constantes.  The use of a simple self-sealing slot results in insufficient sealing which is detrimental to the use of this device for products that are very sensitive to degradation in contact with the air and to obtain a constant unit dose distribution.
De plus, l'emploi d'un obturateur de type spatule souple donne un caractère flexible limité à l'embout, ce qui est préjudiciable à la délivrance du produit dans une zone peu accessible.  In addition, the use of a flexible spatula shutter type gives a limited flexibility to the tip, which is detrimental to the delivery of the product in a poorly accessible area.
L'invention résout ces problèmes grâce à un dispositif de conditionnement et de distribution de produits fluides, liquides ou pâteux, pourvu d'un embout prolongateur qui soit de constitution particulièrement simple, tout en permettant de délivrer le produit dans une zone peu accessible.  The invention solves these problems through a device for packaging and dispensing fluid products, liquid or pasty, provided with an extension tip which is of particularly simple constitution, while allowing to deliver the product in an inaccessible area.
Pour ce faire, l'invention propose un dispositif distributeur de produits fluides pourvu d'un embout prolongateur, connecté par une première extrémité à une buse associée à une pompe doseuse montée sur un flacon contenant le produit à distribuer et comportant à sa seconde extrémité distale un orifice d'évacuation, ledit embout prolongateur portant un obturateur dont une première extrémité est disposée sur ledit orifice d'évacuation, cet obturateur étant destiné à s'ouvrir à sa seconde extrémité distale sous la pression du produit lors de l'actionnement de ladite pompe, et ledit obturateur comportant une partie externe tubulaire, déformable élastiquement en flexion longitudinale, dont une première extrémité est disposée sur l'orifice d'évacuation et dont la section externe de forme affinée diminue régulièrement vers sa seconde extrémité distale, au moins sur une partie de sa longueur, ladite partie externe étant destinée à se déformer élastiquement radialement à sa seconde extrémité distale sous la pression du fluide sortant de la pompe par ladite buse, caractérisé en ce que ledit obturateur comporte à l'intérieur de ladite partie externe, un connecteur tubulaire solidaire dudit orifice d'évacuation de l'embout et une tige de section sensiblement identique à la section interne de la seconde extrémité distale de ladite partie externe, liée par sa première extrémité à ce connecteur par l'intermédiaire d'une articulation et fermant par sa seconde extrémité la seconde extrémité distale de ladite partie externe. To do this, the invention proposes a device for dispensing fluid products provided with an extension nozzle, connected by a first end to a nozzle associated with a metering pump mounted on a bottle containing the product to be dispensed and comprising at its second distal end a discharge orifice, said extension end bearing a shutter having a first end is disposed on said discharge orifice, said shutter being intended to open at its second distal end under the pressure of the product during the actuation of said pump, and said shutter comprising a tubular outer portion, elastically deformable in longitudinal flexion, a first end of which is disposed on the discharge orifice and whose outer section of refined shape regularly decreases towards its second distal end, at least over a part of its length, said external portion being intended to deform elastically radially at its second distal end under the pressure of the fluid exiting the pump through said nozzle, characterized in that what said shutter has inside said outer portion, u n tubular connector secured to said nozzle discharge orifice and a rod of substantially identical section to the inner section of the second distal end of said outer portion, connected by its first end to this connector via a joint and closing at its second end the second distal end of said outer portion.
Grâce à l'invention, la pompe peut ne pas comporter de clapet de sortie. Dans ce cas, grâce à l'étanchéité parfaite de la jonction entre l'embout prolongateur et la pompe elle-même, l'obturateur situé à l'extrémité distale de l'embout prolongateur joue le double rôle de second clapet de la pompe et d'obturateur de l'embout. Ainsi, la pompe ne comporte qu'un seul clapet, le second clapet étant remplacé par l'obturateur de l'embout prolongateur.  Thanks to the invention, the pump may not include an outlet valve. In this case, thanks to the perfect seal of the junction between the extension tip and the pump itself, the shutter located at the distal end of the extension piece acts as double valve second pump and shutter of the mouthpiece. Thus, the pump has only one valve, the second valve being replaced by the shutter of the extension nozzle.
De plus, un tel obturateur permet une utilisation dans une zone peu accessible, par exemple un conduit auditif, de par sa forme affinée et sa flexibilité longitudinale. Il assure également une utilisation sans risque de blessure, que cette utilisation soit effectuée sur un corps humain ou animal. In addition, such a shutter allows use in an inaccessible area, for example an ear canal, because of its refined shape and its longitudinal flexibility. It also ensures use without risk of injury, whether this use is made on a human or animal body.
Selon une première variante de réalisation, ladite articulation est constituée d'une languette flexible solidaire dudit connecteur.  According to a first variant embodiment, said hinge consists of a flexible tongue integral with said connector.
Selon une seconde variante de réalisation, ladite articulation est constituée d'une rotule.  According to a second variant embodiment, said articulation consists of a ball joint.
Avantageusement, ladite rotule est portée par la première extrémité de ladite tige et rotative dans un siège portée par ledit connecteur.  Advantageously, said ball is carried by the first end of said rod and rotatable in a seat carried by said connector.
Ladite tige comporte avantageusement au moins deux nervures longitudinales d'extrémité radiale sensiblement identique à la forme affinée de ladite partie externe, hors sa seconde extrémité de section circulaire.  Said rod advantageously comprises at least two longitudinal ribs of radial end substantially identical to the refined form of said outer portion, outside its second end of circular section.
Avantageusement, ladite partie externe est encliquetée sur ledit connecteur.  Advantageously, said outer portion is snapped onto said connector.
Le dispositif est de préférence du type flacon-poche où le produit à distribuer est contenu dans une poche déformable introduite dans un flacon rigide.  The device is preferably of the pocket-bottle type where the product to be dispensed is contained in a deformable bag introduced into a rigid bottle.
De préférence, la pompe doseuse est une pompe sans entrée d'air, ou pompe dite "airless", montée sur un flacon distributeur du type à piston suiveur ou de préférence du type flacon-poche tel que décrit par exemple dans le document de brevet EP 1 412 263 où le produit à distribuer est contenu dans une poche déformable introduite dans un flacon rigide muni d'une entrée d'air comportant de préférence un obturateur, par exemple un clapet, fermant l'entrée d'air quand la pompe n'est pas actionnée.  Preferably, the metering pump is a pump without air intake, or so-called "airless" pump, mounted on a dispensing bottle of the follower piston type or preferably of the pocket-bottle type as described for example in the patent document. Wherein the product to be dispensed is contained in a deformable bag introduced into a rigid bottle provided with an air inlet preferably comprising a shutter, for example a valve, closing the air inlet when the pump n is not operated.

La figure 4 est une vue en coupe transversale selon A-A.  Figure 4 is a cross-sectional view along A-A.
La figure 5 est une vue en coupe longitudinale de détail de ce même dispositif, selon une seconde variante de réalisation.  Figure 5 is a longitudinal sectional view of detail of the same device, according to a second embodiment.
La figure 6 est une vue en coupe longitudinale de détail de ce même dispositif, selon cette seconde variante de réalisation, en position repliée.  Figure 6 is a longitudinal sectional view of the same device, according to this second embodiment, in the folded position.
La figure 1 représente un dispositif distributeur de produits fluides, liquides ou pâteux, pourvu d'un embout prolongateur 4, connecté par une première extrémité à une buse associée à une pompe doseuse montée sur un flacon contenant le produit à distribuer et comportant à son extrémité distale un orifice d'évacuation.  FIG. 1 represents a liquid or pasty fluid dispenser device, provided with an extension nozzle 4, connected by a first end to a nozzle associated with a metering pump mounted on a bottle containing the product to be dispensed and having at its end distal an evacuation orifice.
Le prolongateur peut être réalisé en toute matière appropriée, de préférence rigide, telle qu'un polyéthylène ou un polypropylène de densité appropriée pour lui conférer les propriétés mécaniques voulues.  The extender may be made of any suitable material, preferably rigid, such as polyethylene or polypropylene of appropriate density to impart the desired mechanical properties.
Le dispositif comporte un boîtier rigide 1 muni d'un poussoir 2 actionnant la pompe sans reprise d'air de type usuel. La pompe permet d'extraire le produit contenu dans le flacon pour le distribuer en le faisant sortir par la buse 3 et l'embout prolongateur tubulaire 4 à travers un obturateur 5 disposé sur l'orifice d'évacuation, cet obturateur étant destiné à s'ouvrir sous la pression du produit lors de l'actionnement de la pompe. Le tube 4 forme un coude à la sortie de la tête 3.  The device comprises a rigid housing 1 provided with a pusher 2 actuating the pump without air intake of the usual type. The pump makes it possible to extract the product contained in the bottle to distribute it by taking it out through the nozzle 3 and the tubular extension nozzle 4 through a shutter 5 disposed on the discharge orifice, this shutter being intended for 'open under the pressure of the product when operating the pump. The tube 4 forms an elbow at the outlet of the head 3.
L'embout prolongateur 4 porte donc cet obturateur 5 dont une première extrémité 5A est disposée sur l'orifice d'évacuation, cet obturateur 5 étant destiné à s'ouvrir à sa seconde extrémité 5B sous la pression du produit lors de l'actionnement de la pompe. The extension piece 4 thus carries this shutter 5, a first end 5A of which is disposed on the discharge orifice, this shutter 5 being intended to open at its second end 5B under the pressure of the product during actuation of the pump.
Les figures 2 à 4 représentent une première variante de réalisation.  Figures 2 to 4 show a first embodiment.
L'obturateur 5 comporte une partie externe tubulaire 6. Cette partie externe 6 est déformable élastiquement en flexion longitudinale, sa première extrémité 6A étant disposée sur l'orifice d'évacuation et sa section externe diminuant régulièrement vers sa seconde extrémité distale 6B au moins sur une partie de sa longueur.  The shutter 5 comprises a tubular outer portion 6. This outer portion 6 is elastically deformable in longitudinal flexion, its first end 6A being disposed on the discharge orifice and its external section regularly decreasing towards its second distal end 6B at least on part of its length.
Cette partie externe 6 est également destinée à se déformer élastiquement radialement à sa seconde extrémité distale 6B sous la pression du fluide sortant de la pompe par la buse. Elle peut ainsi se déformer pour laisser passer le produit sortant de l'embout 4, quand la pompe est actionnée par pression sur le poussoir 2, pour reprendre sa position d'obturation quand le poussoir est relâché.  This outer portion 6 is also intended to deform elastically radially at its second distal end 6B under the pressure of the fluid exiting the pump through the nozzle. It can thus deform to let the product leaving the nozzle 4, when the pump is actuated by pressing the pusher 2, to resume its closed position when the pusher is released.
Cette partie externe 6 est en un matériau tel que du caoutchouc synthétique ou naturel, du silicone ou un élastomère, ou un thermoplastique, notamment un élastomère thermoplastique éventuellement souple, de préférence en élastomère nitrile, butyle silicone ou en polyuréthane.  This external part 6 is made of a material such as synthetic or natural rubber, silicone or an elastomer, or a thermoplastic, in particular an optionally flexible thermoplastic elastomer, preferably made of nitrile elastomer, silicone butyl or polyurethane.
Pour ce faire, plus précisément, l'obturateur 5 comporte à l'intérieur de cette partie externe 6, un connecteur tubulaire 7 solidaire de l'orifice d'évacuation de l'embout 4 et une tige 8 de section sensiblement identique à la section interne de la seconde extrémité distale de ladite partie externe, liée par sa première extrémité 8A à ce connecteur 7 par l'intermédiaire d'une articulation et fermant par sa seconde extrémité distale 8B, de préférence de section circulaire, la seconde extrémité distale 6B de la partie externe. Elle assure ainsi la fermeture de l'obturateur en l'absence de pression du produit et une bonne étanchéité vis-à-vis de l'extérieur de telle sorte que l'air extérieur ne puisse pas pénétrer dans l'embout et atteindre le produit qui s'y trouve, entre deux actionnements successifs de la pompe par l'utilisateur. To do this, more precisely, the shutter 5 comprises inside this outer portion 6, a tubular connector 7 integral with the outlet orifice of the nozzle 4 and a rod 8 of section substantially identical to the section internal of the second distal end of said outer portion, connected by its first end 8A to this connector 7 by means of a hinge and closing by its second distal end 8B, preferably of circular section, the second distal end 6B of the outer part. It thus ensures the closure of the shutter in the absence of product pressure and a good seal with respect to the outside so that the outside air can not penetrate into the tip and reach the product therein, between two successive actuations of the pump by the user.
Par contre, lors de l'actionnement de la pompe, du produit est délivré par l'orifice d'évacuation de l'embout 4, traverse l'obturateur 5 et vient écarter radialement la seconde extrémité distale 6B de la partie externe 6 autour de l'extrémité 8B de la tige, pour être déposé à l'emplacement souhaité.  On the other hand, when the pump is actuated, the product is delivered through the discharge orifice of the nozzle 4, passes through the shutter 5 and radially spreads the second distal end 6B of the outer portion 6 around end 8B of the rod, to be deposited at the desired location.
Selon cette première variante de réalisation, l'articulation est constituée d'une languette cylindrique flexible 9 solidaire du connecteur 7.  According to this first variant embodiment, the articulation consists of a flexible cylindrical tongue 9 secured to the connector 7.
La tige 8 comporte au moins deux nervures longitudinales, de préférence quatre nervures 8C en forme de croix, d'extrémité radiale sensiblement identique à la forme affinée de la partie externe 6, hors sa seconde extrémité distale 8B de section circulaire. Cet agencement de nervures assure que la tige 8 ne colle pas à la partie externe 6 et également assure une diminution progressive de la section de passage du produit dans l'obturateur 5, afin que ce dernier ne sorte pas de façon brutale de l'obturateur 5.  The rod 8 comprises at least two longitudinal ribs, preferably four cross-shaped ribs 8C, radial end substantially identical to the refined shape of the outer portion 6, its second distal end 8B of circular section. This arrangement of ribs ensures that the rod 8 does not stick to the outer portion 6 and also ensures a gradual decrease in the passage section of the product in the shutter 5, so that the latter does not come out of the shutter abruptly 5.
Selon l'exemple représenté, le connecteur 7 est monté à force sur l'embout 4 à son orifice d'évacuation et la partie externe 6 est encliquetée sur le connecteur 7.  According to the example shown, the connector 7 is force-fitted on the nozzle 4 at its discharge orifice and the external part 6 is snapped onto the connector 7.
Selon une seconde variante de réalisation, représentée sur la figure 5 et 6, l'articulation est constituée d'une rotule 10.  According to a second variant embodiment, represented in FIGS. 5 and 6, the articulation consists of a ball joint 10.
Avantageusement, la rotule 10 est portée par la première extrémité 8A de la tige 8 et rotative dans un siège 11 porté par le connecteur 7.  Advantageously, the ball 10 is carried by the first end 8A of the rod 8 and rotating in a seat 11 carried by the connector 7.
A part cette différence, cette seconde variante de réalisation est identique à la première variante de réalisation précédemment décrite. Le dispositif est de préférence est du type flacon-poche où le produit à distribuer est contenu dans une poche déformable introduite dans un flacon rigide. Apart from this difference, this second variant embodiment is identical to the first embodiment variant previously described. The device is preferably of the pocket-bottle type where the product to be dispensed is contained in a deformable bag introduced into a rigid bottle.
Grâce à la forme affinée de la partie externe 6 de l'obturateur, cette partie peut être aisément introduite en un emplacement de section réduite, tel un canal auditif.  Thanks to the refined shape of the outer part 6 of the shutter, this part can be easily introduced in a reduced section location, such as an auditory canal.
Grâce à l'articulation de la tige 8 et à la l'élasticité en flexion de la partie externe 6 de l'obturateur, ce dernier peut être orienté comme représenté sur les figure 3 et 6, pour accéder et délivrer le produit dans une partie corporelle d'accès indirect ou difficile, et sans risque de blessures.  Thanks to the articulation of the rod 8 and to the bending elasticity of the outer part 6 of the shutter, the latter can be oriented as shown in FIGS. 3 and 6, to access and deliver the product in a part indirect or difficult access and without risk of injury.
