Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention concerne un embout de distribution de fluide qui comporte un couvercle lui conférant des propriétés bactéricides et/ou bactériostatiques.The invention relates to a fluid dispensing tip which has a cover which gives it bactericidal and / or bacteriostatic properties.

Un tel embout de distribution est particulièrement avantageux pour une application à la distribution de produits cosmétiques, pharmaceutiques ou alimentaires par exemple, qui sont destinés à venir en contact avec la peau. En effet, l'embout permet de distribuer un produit sans risques de contaminer le produit.Such a dispensing tip is particularly advantageous for an application to the dispensing of cosmetic, pharmaceutical or food products for example, which are intended to come into contact with the skin. Indeed, the tip makes it possible to dispense a product without risk of contaminating the product.

ÉTAT DE LA TECHNIQUE ANTÉRIEURESTATE OF THE PRIOR ART

De nombreux produits fluides, c'est-à-dire qui se présentent sous forme pâteuse ou liquide sont contenus dans un récipient qui permet à la fois la conservation du produit et la distribution de celui-ci.Many fluid products, that is to say products which are in pasty or liquid form, are contained in a container which allows both the preservation of the product and the distribution thereof.

La conservation du produit est généralement assurée grâce à un récipient hermétique à l'air et aussi en introduisant dans le produit des éléments conservateurs, antioxydants, bactéricides etc.The preservation of the product is generally ensured by means of an airtight container and also by introducing into the product preservatives, antioxidants, bactericides, etc.

Une source de pollution du produit est aussi située au niveau du dispositif de distribution. En effet, le dispositif de distribution comporte une ouverture de sortie du produit au niveau de laquelle de l'air peut pénétrer à l'intérieur du contenant et polluer le produit.A source of product pollution is also located at the level of the distribution device. Indeed, the dispensing device comprises an outlet opening for the product at which air can penetrate inside the container and pollute the product.

Aussi, le prélèvement du produit s'effectue en balayant la surface externe du dispositif, par exemple avec le doigt, la langue ou toute autre partie du corps humain. Cette action de balayage apporte des bactéries ou autres éléments polluants sur la surface externe, mais aussi dissémine ceux-ci.Also, the product is taken by scanning the external surface of the device, for example with the finger, the tongue or any other part of the human body. This sweeping action brings bacteria or other polluting elements to the external surface, but also disseminates them.

Un embout de distribution est l'interface entre le réservoir contenant le produit à distribuer et l'utilisateur qui prélève ce produit.A dispensing tip is the interface between the reservoir containing the product to be dispensed and the user who takes this product.

L'embout comporte à cet effet un orifice de distribution qui débouche à la fois dans le réservoir et sur une face de prélèvement de l'embout, et c'est au travers de cet orifice que le produit à prélever sort du réservoir.For this purpose, the nozzle comprises a dispensing orifice which opens both into the reservoir and onto a withdrawal face of the nozzle, and it is through this orifice that the product to be withdrawn leaves the reservoir.

La face de prélèvement constitue l'interface au niveau laquelle l'utilisateur a accès au produit.The withdrawal face constitutes the interface at which the user has access to the product.

Cette face de prélèvement est exposée à l'air libre ainsi qu'au contact avec de nombreux éléments tels qu'un doigt de l'utilisateur.This sampling face is exposed to the open air as well as to contact with numerous elements such as a user's finger.

Chacune de ces expositions de la face de prélèvement implique un risque de contamination de celle-ci, et un risque que le contaminant soit transféré au produit prélevé.Each of these exposures of the sampling face involves a risk of contamination thereof, and a risk that the contaminant is transferred to the sampled product.

Le document FR-A-2.791.955 décrit un embout de distribution comportant un couvercle amovible et un élément d'obturation de l'orifice de distribution, qui est apte à venir en contact avec une partie de la face de prélèvement.The document FR-A-2,791,955 describes a dispensing tip comprising a removable cover and an element for closing off the dispensing orifice, which is able to come into contact with a part of the sampling face.

Selon ce document, l'élément d'obturation comporte une substance bactéricide/bactériostatique qui permet de traiter le produit restant au niveau de l'orifice.According to this document, the closure element comprises a bactericidal / bacteriostatic substance which makes it possible to treat the product remaining at the level of the orifice.

Cependant, un tel élément d'obturation est particulièrement difficile à réaliser et à mettre en œuvre, ce qui augmente par conséquent les coûts de fabrication de l'embout de distribution. De plus, ce document n'enseigne ni la nature, ni la concentration de l'élément bactéricide, ni son homogénéité.However, such a closure element is particularly difficult to produce and implement, which consequently increases the manufacturing costs of the dispensing nozzle. In addition, this document does not teach either the nature or the concentration of the bactericidal element, or its homogeneity.

De plus, l'élément d'obturation peut être soumis à des risques d'usure, de telle manière que son contact avec la face de prélèvement n'est plus optimal, ou bien la quantité de substance bactéricide/bactériostatique qu'il contient peut diminuer au fur et à mesure de ses utilisations.In addition, the closure element may be subjected to risks of wear, such that its contact with the sampling face is no longer optimal, or else the quantity of bactericidal / bacteriostatic substance that it contains may decrease as it is used.

Les documents EP 1649775 A1 , GB-869580 , US-2232140 , US-6053184 et US-2004247373 décrivent des embout de distribution faisant partie de l'état de l'art antérieur à l'invention.The documents EP 1649775 A1 , GB-869580 , US-2232140 , US-6053184 and US-2004247373 describe dispensing tips forming part of the state of the art prior to the invention.

L'invention a pour but de proposer un embout de distribution ayant des propriétés bactéricides/bactériostatiques qui sont sensiblement constantes sur toute la durée d'utilisation du réservoir sur lequel l'embout est monté.The object of the invention is to provide a dispensing tip having bactericidal / bacteriostatic properties which are substantially constant over the entire period of use of the reservoir on which the tip is mounted.

Lorsqu'une pression est exercée sur les parois du récipient, la pression du fluide augmente et l'élément déformable 26 est conçu pour que la fente 28 s'ouvre sous l'action de la pression du fluide pour ouvrir l'orifice de distribution 16 et par conséquent permettre à une certaine quantité de fluide de sortir au travers de l'orifice de distribution 16 sous l'action de cette même pression.When pressure is exerted on the walls of the container, the pressure of the fluid increases and the deformable element 26 is designed so that the slot 28 opens under the action of the pressure of the fluid to open the dispensing orifice 16. and consequently allow a certain quantity of fluid to exit through the dispensing orifice 16 under the action of this same pressure.

Lorsque la pression sur les parois du récipient 12 est relâchée, l'élément déformable revient alors élastiquement dans sa configuration initiale de fermeture hermétique de l'orifice de distribution 16.When the pressure on the walls of the container 12 is released, the deformable element then returns elastically to its initial configuration of hermetically sealing the dispensing orifice 16.

Un tel obturateur à fente 20 permet d'empêcher la contamination du fluide contenu dans le récipient par de l'air ou d'autres contaminants, tels que des bactéries.Such a slit stopper 20 makes it possible to prevent contamination of the fluid contained in the container by air or other contaminants, such as bacteria.

L'embout de distribution 10 comporte aussi un couvercle amovible 30 qui est mobile par rapport au corps principal 14 entre une position de fermeture de l'orifice de distribution 16 représentée à la figure 2, dans laquelle le couvercle 30 recouvre l'orifice de distribution 16 et la face d'application 18, et une position de dégagement représentée à la figure 1, dans laquelle le couvercle 30 permet l'accès à la face d'application 18 et à l'orifice 16.The dispensing tip 10 also comprises a removable cover 30 which is movable relative to the main body 14 between a closed position of the dispensing orifice 16 shown in FIG. figure 2 , in which the cover 30 covers the dispensing orifice 16 and the application face 18, and a release position shown in figure 1 , in which the cover 30 allows access to the application face 18 and to the orifice 16.

Le couvercle 30 comporte principalement une paroi de fermeture 46 qui vient en vis-à-vis de, et de préférence, en contact avec la face d'application 18. Cette paroi de fermeture comporte une face 48 située en vis-à-vis de la face d'application 18 qui est de forme complémentaire à la face d'application 18. Ici, la face d'application 18 est plane, la face 48 de la paroi de fermeture 46 est par conséquent elle aussi plane.The cover 30 mainly comprises a closure wall 46 which comes opposite, and preferably, in contact with the application face 18. This closure wall comprises a face 48 situated opposite. the application face 18 which is of complementary shape to the application face 18. Here, the application face 18 is flat, the face 48 of the closure wall 46 is therefore also flat.

Il sera compris que l'invention n'est pas limitée à cette forme de la face d'application 18 et de la face en vis-à-vis de la paroi de fermeture 46 qui peuvent aussi être concaves ou convexes.It will be understood that the invention is not limited to this shape of the application face 18 and of the face facing the closure wall 46 which can also be concave or convex.

Selon le mode de réalisation représenté aux figures 1 et 2, le couvercle 30 est monté articulé par rapport au corps principal 14 de l'embout 10.According to the embodiment shown in figures 1 and 2 , the cover 30 is mounted articulated relative to the main body 14 of the nozzle 10.

De préférence, les moyens 32 réalisant l'articulation du couvercle 30 par rapport au corps 14 sont situés au niveau de premiers bords respectifs du couvercle 30 et du corps 14, qui sont ici situés du côté gauche des figures 1 et 2.Preferably, the means 32 providing the articulation of the cover 30 relative to the body 14 are located at the level of respective first edges of the cover 30 and of the body 14, which are here located on the left side of the figures 1 and 2 .

Le couvercle 30 et le corps 14 comportent aussi des moyens de blocage du couvercle 30 en position de fermeture.The cover 30 and the body 14 also include means for locking the cover 30 in the closed position.

Ces moyens de blocage sont de préférence des moyens de blocage par emboitement élastique, ou encliquetage, et comportent un crochet élastique 34 porté par un deuxième bord du couvercle 30, qui est opposé au premier bord du couvercle 30, qui porte les moyens d'articulation 32. Lorsque le couvercle 30 est en position de fermeture, le crochet élastique 34 coopère avec une dent associée 36 formée sur un deuxième bord du corps 14, qui est opposé au premier bord du corps 14 qui porte les moyens d'articulation 32.These locking means are preferably locking means by elastic interlocking, or snap-fastening, and comprise an elastic hook 34 carried by a second edge of the cover 30, which is opposite the first edge of the cover 30, which carries the articulation means. 32. When the cover 30 is in the closed position, the elastic hook 34 cooperates with an associated tooth 36 formed on a second edge of the body 14, which is opposite the first edge of the body 14 which carries the articulation means 32.

Selon un autre mode de réalisation représenté à la figure 3, le couvercle 30 se monte sur le corps 14 par vissage.According to another embodiment shown in figure 3 , the cover 30 is mounted on the body 14 by screwing.

A cet effet, le couvercle 30 comporte une paroi cylindrique 38 qui prolonge axialement les bords de la paroi de fermeture 46 et dont la face interne comporte un taraudage 40 qui est apte à coopérer avec un filetage complémentaire 42 formé sur la paroi cylindrique externe du corps 14. La paroi cylindrique 38 du couvercle comporte des évents 44 permettant à l'air emprisonné entre le couvercle et le corps 14 de s'échapper vers l'extérieur lorsque l'on visse le couvercle 30.For this purpose, the cover 30 comprises a cylindrical wall 38 which axially extends the edges of the closing wall 46 and whose internal face comprises a thread 40 which is able to cooperate with a complementary thread 42 formed on the external cylindrical wall of the body. 14. The cylindrical wall 38 of the cover has vents 44 allowing the air trapped between the cover and the body 14 to escape to the outside when the cover 30 is screwed on.

La face d'application 18 est en contact prolongé avec l'air et elle est susceptible de recevoir des contaminants, tels que des bactéries, notamment lorsque l'utilisateur vient en contact avec celle-ci lorsqu'il prélève le fluide présent sur la face d'application 18.The application face 18 is in prolonged contact with the air and it is liable to receive contaminants, such as bacteria, in particular when the user comes into contact with it when he takes the fluid present on the face. application 18.

Les contaminants qui se déposent sur la face d'application 18 peuvent alors se transférer au fluide lors d'une utilisation suivante du distributeur de produit.The contaminants which are deposited on the application face 18 can then be transferred to the fluid during a subsequent use of the product dispenser.

Pour détruire ces contaminants, notamment les bactéries qui pourraient se développer sur la face d'application 18 entre deux utilisations, l'embout comporte une couche de matériau bactéricide/bactériostatique 50 présentant des propriétés bactéricides et/ou bactériostatiques, qui est apte à venir en contact avec la face d'application 18.To destroy these contaminants, in particular the bacteria which could develop on the application face 18 between two uses, the end piece comprises a layer of bactericidal / bacteriostatic material 50 exhibiting bactericidal and / or bacteriostatic properties, which is capable of coming into existence. contact with the application face 18.

Selon un mode de réalisation préféré, la couche de matériau bactéricide/bactériostatique 50 est portée par le couvercle 30.According to a preferred embodiment, the layer of bactericidal / bacteriostatic material 50 is carried by the cover 30.

Ainsi, la fermeture et l'ouverture du couvercle permettent à la couche de matériau bactéricide/bactériostatique 50 de venir en contact ou de s'éloigner de la face d'application 18, respectivement.Thus, closing and opening the cover allows the layer of bactericidal / bacteriostatic material 50 to come into contact or move away from the application face 18, respectively.

De préférence, la couche de matériau bactéricide/bactériostatique 50 est située sur la face 48 de la paroi de fermeture 46 du boitier 30. Ainsi, lorsque le boitier 30 est en position de fermeture, comme on l'a représenté à la figure 2, la couche de matériau bactéricide/bactériostatique 50 est en contact avec la face d'application 18, permettant ainsi de détruire les contaminants.Preferably, the layer of bactericidal / bacteriostatic material 50 is located on the face 48 of the closure wall 46 of the housing 30. Thus, when the housing 30 is in the closed position, as shown in FIG. figure 2 , the layer of bactericidal / bacteriostatic material 50 is in contact with the application face 18, thus making it possible to destroy the contaminants.

Ici aussi, la forme de la couche de matériau bactéricide/bactériostatique 50, et plus précisément la forme de sa face 52 située en vis-à-vis de la face d'application 18 est complémentaire de la forme de la face d'application 18.Here too, the shape of the layer of bactericidal / bacteriostatic material 50, and more precisely the shape of its face 52 located opposite the application face 18 is complementary to the shape of the application face 18 .

Ici, la face d'application 18 est plane, la face 52 de la couche de matériau bactéricide/bactériostatique 50 est par conséquent elle aussi plane.Here, the application face 18 is flat, the face 52 of the layer of bactericidal / bacteriostatic material 50 is therefore also flat.

Il sera compris que l'invention n'est pas limitée à cette forme de la face d'application 18 et de face 52 de la couche de matériau bactéricide/bactériostatique 50 qui peuvent aussi être concaves ou convexes.It will be understood that the invention is not limited to this shape of the application face 18 and face 52 of the layer of bactericidal / bacteriostatic material 50 which can also be concave or convex.

De préférence, la couche de matériau bactéricide/bactériostatique 50 est réalisée à partir de cuivre ou d'argent, qui sont des matériaux naturellement bactéricides/bactériostatiques, ou bien à base de tout autre alliage bactéricide, notamment un alliage à base de cuivre et/ou d'argent. Ainsi, la couche de matériau bactéricide/bactériostatique 50 ne perd pas ses propriétés au fur et à mesure de son utilisation. De plus, ces matériaux sont peu couteux et faciles à mettre en œuvre par rapport à des compositions bactéricides/bactériostatiques spécifiques qui doivent être mises au point en laboratoire.Preferably, the layer of bactericidal / bacteriostatic material 50 is made from copper or silver, which are naturally bactericidal / bacteriostatic materials, or else based on any other bactericidal alloy, in particular an alloy based on copper and / or money. Thus, the layer of bactericidal / bacteriostatic material 50 does not lose its properties as it is use. In addition, these materials are inexpensive and easy to process compared to specific bactericidal / bacteriostatic compositions which must be developed in the laboratory.

Selon un premier mode de réalisation, la couche de matériau bactéricide/bactériostatique 50 consiste en une plaque mince qui est collée sur ladite face 48 de la paroi de fermeture 46 du boitier 30.According to a first embodiment, the layer of bactericidal / bacteriostatic material 50 consists of a thin plate which is bonded to said face 48 of the closure wall 46 of the housing 30.

Selon un autre mode de réalisation, la couche de matériau bactéricide/bactériostatique 50 est déposée sur ladite face 48 de la paroi de fermeture 46 du boitier 30. Par ce mode de réalisation, une quantité faible mais suffisante de matériau bactéricide/bactériostatique est utilisée.According to another embodiment, the layer of bactericidal / bacteriostatic material 50 is deposited on said face 48 of the closure wall 46 of the housing 30. By this embodiment, a small but sufficient quantity of bactericidal / bacteriostatic material is used.
