Definitions

  • cosmetic product is understood to mean a product as defined in Council Directive 93/35 EEC, dated June 14, 1993.
  • the cosmetic product is advantageously in fluid form. It is for example in the form of a liquid, a cream or possibly a powder.
  • the cosmetic product is intended to be applied to a body surface formed for example by the skin or the keratinous fibers of a human being.
  • the product is dispensed from the reservoir through a dispensing opening in the mouthpiece to a receiving surface placed away from the device.
  • This receiving surface can be directly a body surface of a user.
  • the receiving surface is located in a receptacle or on an application tool, for the indirect application of the cosmetic product to a body surface of the user.
  • the microbial pollution of a cosmetic product contained in the reservoir essentially results from the contact that can occur between a body surface of a user of the device and the product present on the device.
  • the user of the device takes the product with his finger that comes directly into contact with the dispensing tip or applies his finger on the tip to clean once the product is dispensed.
  • FR 2,650,255 and WO 2008/061041 describe dispensers of cosmetic product of the aforementioned type, wherein the tip is provided with a resilient closure valve. This valve only opens when the cosmetic product is dispensed and is closed immediately after the end of the distribution, which is likely to limit the potential contamination of the product in the tank.
  • GB 834 873 , GB 2,184,493 and EP 1 293 440 disclose cosmetic product dispensers which do not include protective means not coming into contact with the dispensed cosmetic product. In addition, these dispensers do not include a shutter operable relative to the nozzle between a closed configuration and an open configuration.
  • An object of the invention is therefore to provide a cosmetic product dispenser which offers an adequate distribution of product, while further limiting the risk of microbial contamination of the formula contained in the dispensing device, in particular when this formula does not contain preservative.

  • the cosmetic product is advantageously a viscosity cream of between 30 poises and 100 poises.
  • the cosmetic product is devoid of a preservative agent capable of preventing bacterial proliferation.
  • Such preserving agents are, for example, alcohols, glycols, parabens, benzoic acids, sodium benzoate, sorbic acid, potassium sorbate, salicylic acid, sodium salicylate, phenoxyethanol and chlorphenesin. .

Description

La présente invention concerne un distributeur de produit cosmétique sur une surface de réception, du type comprenant :

  • un embout définissant un orifice de distribution de produit, propre à s'ouvrir en regard d'une surface de réception disposée sous l'embout,
  • des moyens de protection de l'orifice de distribution pour faire obstacle au contact entre une surface corporelle d'un utilisateur du distributeur et l'orifice de distribution, les moyens de protection faisant saillie vers le bas au-delà de l'embout en délimitant une ouverture de passage de produit cosmétique.
The present invention relates to a cosmetic product dispenser on a receiving surface, of the type comprising:
  • a nozzle defining a product dispensing orifice, adapted to open facing a receiving surface disposed under the nozzle,
  • means for protecting the dispensing orifice in order to prevent contact between a body surface of a user of the dispenser and the dispensing orifice, the protection means projecting downwards beyond the mouthpiece and delimiting a cosmetic product opening opening.

Par « produit cosmétique », on entend notamment au sens de la présente invention, un produit tel que défini dans la Directive 93/35 CEE du Conseil, datée du 14 juin 1993.For the purposes of the present invention, the term "cosmetic product" is understood to mean a product as defined in Council Directive 93/35 EEC, dated June 14, 1993.

Le produit cosmétique est avantageusement sous forme fluide. Il est par exemple sous forme d'un liquide, d'une crème ou éventuellement d'une poudre.The cosmetic product is advantageously in fluid form. It is for example in the form of a liquid, a cream or possibly a powder.

Le produit cosmétique est destiné à être appliqué sur une surface corporelle formée par exemple par la peau ou les fibres kératiniques d'un être humain.The cosmetic product is intended to be applied to a body surface formed for example by the skin or the keratinous fibers of a human being.

On connaît de WO 03033398 , US 7,543,397 , US 2007/095,855 , JP 3830691 , US 6,834,780 , FR 2690423 , FR 2 839 952 et FR 2 899 136 différents dispositifs de distribution de produit cosmétique qui sont munis d'un réservoir contenant du produit cosmétique et d'un distributeur présentant un embout de distribution de produit.We know WO 03033398 , US 7,543,397 , US 2007 / 095,855 , JP 3830691 , US 6,834,780 , FR 2690423 , FR 2,839,952 and FR 2 899 136 various cosmetic product dispensing devices which are provided with a reservoir containing cosmetic product and a dispenser having a product dispensing tip.

Le produit est distribué à partir du réservoir à travers une ouverture de distribution ménagée dans l'embout, jusqu'à une surface de réception placée à l'écart du dispositif.The product is dispensed from the reservoir through a dispensing opening in the mouthpiece to a receiving surface placed away from the device.

Cette surface de réception peut être directement une surface corporelle d'un utilisateur. En variante, la surface de réception est située dans un réceptacle ou sur un outil d'application, en vue de l'application indirecte du produit cosmétique sur une surface corporelle de l'utilisateur.This receiving surface can be directly a body surface of a user. Alternatively, the receiving surface is located in a receptacle or on an application tool, for the indirect application of the cosmetic product to a body surface of the user.

Pour améliorer l'hygiène du dispositif, il peut être souhaitable de limiter au minimum la pollution du produit cosmétique contenu dans le réservoir par des sources microbiennes.To improve the hygiene of the device, it may be desirable to minimize the pollution of the cosmetic product contained in the reservoir by microbial sources.

La pollution microbienne d'un produit cosmétique contenu dans le réservoir résulte essentiellement du contact qui peut se produire entre une surface corporelle d'un utilisateur du dispositif et le produit présent sur le dispositif.The microbial pollution of a cosmetic product contained in the reservoir essentially results from the contact that can occur between a body surface of a user of the device and the product present on the device.

A cet égard, dans certains cas, l'utilisateur du dispositif prélève le produit avec son doigt qui vient directement au contact de l'embout de distribution ou encore applique son doigt sur l'embout pour le nettoyer une fois le produit distribué.In this regard, in some cases, the user of the device takes the product with his finger that comes directly into contact with the dispensing tip or applies his finger on the tip to clean once the product is dispensed.

Pour supprimer ou au moins limiter le problème de pollution microbienne, il est connu de formuler le produit cosmétique avec un agent conservateur permettant d'éviter la prolifération microbienne.To eliminate or at least limit the problem of microbial pollution, it is known to formulate the cosmetic product with a preservative to prevent microbial growth.

FR 2 650 255 et WO 2008/061041 décrivent des distributeurs de produit cosmétique du type précité, dans lequel l'embout est muni d'une valve à fermeture élastique. Cette valve ne s'ouvre donc que lorsque le produit cosmétique est distribué et s'obture immédiatement après la fin de la distribution, ce qui est susceptible de limiter la contamination éventuelle du produit contenu dans le réservoir. FR 2,650,255 and WO 2008/061041 describe dispensers of cosmetic product of the aforementioned type, wherein the tip is provided with a resilient closure valve. This valve only opens when the cosmetic product is dispensed and is closed immediately after the end of the distribution, which is likely to limit the potential contamination of the product in the tank.

Lors de l'utilisation du distributeur décrit dans WO 2008/0610041 , le produit s'écoule par gravité à travers la valve ouverte jusqu'à la surface de réception.When using the dispenser described in WO 2008/0610041 the product flows by gravity through the open valve to the receiving surface.

GB 834 873 , GB 2 184 493 et EP 1 293 440 décrivent des distributeurs de produit cosmétique qui ne comprennent pas de moyens de protection n'entrant pas en contact avec le produit cosmétique distribué. En outre, ces distributeurs ne comprennent pas d'obturateur manoeuvrable par rapport à l'embout entre une configuration fermée et une configuration ouverte. GB 834 873 , GB 2,184,493 and EP 1 293 440 disclose cosmetic product dispensers which do not include protective means not coming into contact with the dispensed cosmetic product. In addition, these dispensers do not include a shutter operable relative to the nozzle between a closed configuration and an open configuration.

En pratique, ces distributeurs ne donnent pas entière satisfaction en ce qui concerne la contamination microbienne.In practice, these distributors are not entirely satisfied with respect to microbial contamination.

Un but de l'invention est donc de fournir un distributeur de produit cosmétique qui offre une distribution adéquate de produit, tout en limitant encore le risque de contamination microbienne de la formule contenue dans le dispositif de distribution, en particulier lorsque cette formule ne contient pas d'agent conservateur.An object of the invention is therefore to provide a cosmetic product dispenser which offers an adequate distribution of product, while further limiting the risk of microbial contamination of the formula contained in the dispensing device, in particular when this formula does not contain preservative.

Ce dispositif 10 comprend un récipient 14 de conditionnement du produit 12 et un distributeur 16 de produit cosmétique selon l'invention monté à l'extrémité inférieure du récipient 14 pour distribuer du produit 12 sur une surface de réception 18 visible sur la Figure 4.This device 10 comprises a container 14 for packaging the product 12 and a cosmetic product dispenser 16 according to the invention mounted at the lower end of the device. container 14 for dispensing product 12 on a receiving surface 18 visible on the Figure 4 .

Le produit cosmétique 12 est avantageusement sous forme fluide. Il est formé par un liquide, une crème, ou éventuellement une poudre destinée à être appliquée sur une surface corporelle d'un utilisateur comme la peau ou les fibres kératiniques.The cosmetic product 12 is advantageously in fluid form. It is formed by a liquid, a cream, or possibly a powder intended to be applied to a body surface of a user such as skin or keratinous fibers.

Le produit cosmétique est avantageusement une crème de viscosité comprise entre 30 poises et 100 poises.The cosmetic product is advantageously a viscosity cream of between 30 poises and 100 poises.

Avantageusement, le produit cosmétique est dépourvu d'agent conservateur propre à empêcher la prolifération bactérienne.Advantageously, the cosmetic product is devoid of a preservative agent capable of preventing bacterial proliferation.

De tels agents conservateurs sont par exemple les alcools, les glycols, les parabènes, les acides benzoïques, le benzoate de sodium, l'acide sorbique, le sorbate de potassium, l'acide salicylique, le salicylate de sodium, le phénoxyéthanol, le chlorphénésine.Such preserving agents are, for example, alcohols, glycols, parabens, benzoic acids, sodium benzoate, sorbic acid, potassium sorbate, salicylic acid, sodium salicylate, phenoxyethanol and chlorphenesin. .

Plus généralement, ces agents sont décrits dans l'ouvrage « International Cosmetic Ingredient Dictionary and Handbook » Seventh Edition, volume 2, pages 1654 et 1655 .More generally, these agents are described in the book "International Cosmetic Ingredient Dictionary and Handbook" Seventh Edition, Volume 2, pages 1654 and 1655 .

La surface de réception 18 est par exemple délimitée dans un réceptacle tel qu'une coupelle ou une assiette, ou sur un outil d'application, en vue de l'application du produit cosmétique sur une surface corporelle de l'utilisateur. En variante, la surface de réception 18 est la surface corporelle sur laquelle le produit cosmétique doit être appliqué.The receiving surface 18 is for example defined in a receptacle such as a cup or a plate, or on an application tool, for the application of the cosmetic product on a body surface of the user. Alternatively, the receiving surface 18 is the body surface on which the cosmetic product is to be applied.

Comme illustré par les Figures 1 et 2, le récipient 14 est formé dans cet exemple par un flacon allongé d'axe vertical A-A'.As illustrated by Figures 1 and 2 , the container 14 is formed in this example by an elongate bottle of vertical axis A-A '.

Le récipient 14 comprend une paroi latérale 20 sensiblement cylindrique, une paroi supérieure d'obturation 22, solidaire de l'extrémité supérieure de la paroi latérale 20, et un col inférieur, solidaire de l'extrémité inférieure de la paroi latérale 20 par un épaulement 24.The container 14 comprises a substantially cylindrical side wall 20, an upper closure wall 22, integral with the upper end of the side wall 20, and a lower neck, secured to the lower end of the side wall 20 by a shoulder 24.

Les parois 20, 22 et le col 24 délimitent un volume intérieur 26 de conditionnement du produit 12 qui reçoit un piston suiveur 28.The walls 20, 22 and the neck 24 define an internal volume 26 for packaging the product 12 which receives a follower piston 28.

Dans cet exemple, la paroi supérieure 22 est rapportée sur la paroi latérale 20. Elle délimite une ouverture 30 d'égalisation de la pression de part et d'autre du piston suiveur 28, qui débouche dans le volume intérieur 26.In this example, the upper wall 22 is attached to the side wall 20. It defines an opening 30 for equalizing the pressure on either side of the follower piston 28, which opens into the interior volume 26.

Dans cet exemple, le col 24 délimite une ouverture 34 inférieure pour le passage de l'embout du distributeur 16 comme on le verra plus bas.In this example, the neck 24 defines a lower opening 34 for the passage of the tip of the dispenser 16 as will be seen below.

Le piston 28 est monté coulissant le long de la paroi latérale 20 dans le volume 26. De manière connue, il est muni de moyens anti-retour autorisant son déplacement vers le distributeur 16 le long de l'axe A-A' et empêchant son déplacement à l'écart du distributeur 16 le long de l'axe A-A'.The piston 28 is slidably mounted along the side wall 20 in the volume 26. In known manner, it is provided with non-return means allowing its movement towards the distributor 16 along the axis AA 'and preventing its movement away from the distributor 16 along the axis A-A'.

Le distributeur 16 comprend un embout de distribution 40 solidaire du col 24 du récipient, et des moyens 42 de solidarisation de l'embout 40 sur le récipient 20. Selon l'invention, le distributeur 16 comporte en outre des moyens de protection 44 montés à l'extrémité inférieure du récipient 14 pour faire obstacle au contact entre une surface corporelle de l'utilisateur et l'embout de distribution 40, comme on le décrira en détail plus bas.The dispenser 16 comprises a dispensing nozzle 40 integral with the neck 24 of the receptacle, and means 42 for securing the tip 40 to the receptacle 20. According to the invention, the dispenser 16 further comprises protective means 44 mounted in the lower end of the container 14 to prevent contact between a body surface of the user and the dispensing tip 40, as will be described in detail below.

L'embout 40 comprend un corps de base 50 creux et une valve déformable 52 montée à l'extrémité inférieure du corps de base 50 pour obturer le corps de base 50.The tip 40 comprises a hollow base body 50 and a deformable valve 52 mounted at the lower end of the base body 50 for closing the base body 50.

Comme illustré par la Figure 3, le corps de base 50 comprend une jupe périphérique extérieure 54 de liaison au récipient 20, une paroi 56 déformable de liaison, et un manchon 58 de support de la valve 52.As illustrated by Figure 3 , the base body 50 comprises an outer peripheral skirt 54 for connection to the container 20, a deformable connecting wall 56, and a sleeve 58 for supporting the valve 52.

L'embout 40 obture vers le bas le récipient 14 au dessus du col 24. Il fait saillie vers le bas suivant l'axe A-A' à travers l'ouverture inférieure 34 délimitée par le col 24.The tip 40 closes down the container 14 above the neck 24. It projects downwards along the axis A-A 'through the lower opening 34 delimited by the neck 24.

La jupe périphérique 54 est appliquée contre la paroi latérale 20 du récipient 14 au-dessus du col 24.The peripheral skirt 54 is applied against the side wall 20 of the container 14 above the neck 24.

Elle est calée axialement le long de l'axe A-A' vers le bas, par le col 24, et vers le haut, par les moyens de retenue 42.It is wedged axially along the axis A-A 'downwards, by the neck 24, and upwards by the retaining means 42.

La paroi de liaison 56 raccorde le bord supérieur de la jupe périphérique extérieure 54 au bord supérieur du manchon 58. Elle présente sensiblement une forme de révolution autour de l'axe A-A'. Sa section dans un plan vertical passant par l'axe A-A' est convergente vers le bas.The connecting wall 56 connects the upper edge of the outer peripheral skirt 54 to the upper edge of the sleeve 58. It has substantially a shape of revolution about the axis A-A '. Its section in a vertical plane passing through the axis A-A 'is convergent downwards.

Comme on le verra plus bas, la paroi de liaison 56 est déformable axialement par rapprochement de son bord supérieur vers son bord inférieur. Ce rapprochement provoque une diminution du volume intérieur 26 disponible pour contenir du produit cosmétique et l'expulsion de produit cosmétique 20 hors de l'embout 40 à travers la valve 52.As will be seen below, the connecting wall 56 is deformable axially by approaching its upper edge to its lower edge. This approximation causes a decrease in the internal volume 26 available to contain the cosmetic product and the expulsion of cosmetic product 20 from the tip 40 through the valve 52.

Le manchon 58 fait saillie axialement vers le bas hors du col inférieur 24 à travers l'ouverture inférieure 34. Il délimite intérieurement un canal 60 de circulation de produit cosmétique et une gorge annulaire 62 de blocage de la valve qui débouche radialement dans le canal 60.The sleeve 58 protrudes axially downwards from the lower neck 24 through the lower opening 34. It delimits internally a channel 60 for the circulation of cosmetic product and an annular groove 62 for blocking the valve that opens radially into the channel 60. .

Le canal 60 débouche vers le haut dans le volume intérieur 26 et vers le bas à travers une ouverture inférieure délimitée par le bord libre inférieur 64 du manchon 58.The channel 60 opens up into the interior volume 26 and down through a lower opening defined by the lower free edge 64 of the sleeve 58.

Le manchon 58 délimite, au voisinage de la paroi de liaison 56, un épaulement extérieur annulaire 66 et un jonc annulaire extérieur 68 situé sous l'épaulement 66.The sleeve 58 defines, in the vicinity of the connecting wall 56, an annular outer shoulder 66 and an outer annular ring 68 located under the shoulder 66.

La valve 52 est réalisée en une matière plus souple que le corps de base 50. Elle est par exemple réalisée en un élastomère déformable ou en silicone.The valve 52 is made of a softer material than the base body 50. It is for example made of a deformable elastomer or silicone.

La valve 52 comprend une paroi périphérique 70 appliquée contre la surface intérieure du manchon 58 et une paroi inférieure 72 d'obturation du canal 60.The valve 52 comprises a peripheral wall 70 applied against the inner surface of the sleeve 58 and a lower wall 72 for closing the channel 60.

La paroi périphérique 70 présente un rebord supérieur 76 reçu dans la gorge annulaire 62 pour bloquer axialement la valve 52 par rapport au manchon 58.The peripheral wall 70 has an upper flange 76 received in the annular groove 62 for axially locking the valve 52 with respect to the sleeve 58.

La paroi inférieure 72 délimite un orifice de distribution 74 qui débouche axialement vers le bas par rapport à l'axe A-A' et qui débouche vers le haut dans le canal 60.The lower wall 72 delimits a dispensing orifice 74 which opens axially downwards with respect to the axis A-A 'and which opens upwards in the channel 60.

La valve 52 est déformable entre une configuration d'obturation du volume intérieur 26 et du canal 60, dans laquelle l'orifice de distribution 74 est obturé, et une configuration de passage du produit à travers l'orifice de distribution 74, dans laquelle la paroi inférieure 72 a été déformée pour ouvrir l'orifice 74.The valve 52 is deformable between a closed configuration of the inner volume 26 and the channel 60, in which the dispensing orifice 74 is closed, and a configuration of passage of the product through the dispensing orifice 74, in which the lower wall 72 has been deformed to open the orifice 74.

Dans la configuration de passage, un passage continu de produit cosmétique est établi entre le volume intérieur 26 du récipient 14, le canal 60 de circulation de produit défini par l'embout 40 et à travers l'orifice de distribution 74, jusqu'à l'extérieur du dispositif 10.In the passage configuration, a continuous passage of cosmetic product is established between the interior volume 26 of the container 14, the product circulation channel 60 defined by the tip 40 and through the dispensing orifice 74, to the outside the device 10.

Comme on le décrira en détail plus bas, l'embout 40 est mobile par rapport aux moyens de protection 44, conjointement avec le récipient 14, entre une position supérieure de repos, une position intermédiaire de pré-distribution, et une position inférieure de distribution de produit.As will be described in detail below, the tip 40 is movable relative to the protection means 44, together with the container 14, between an upper resting position, an intermediate pre-dispensing position, and a lower dispensing position. of product.

Les moyens de solidarisation 42 de l'embout 40 sur le récipient 14 comprennent, dans cet exemple, un bourrelet annulaire intérieur 75 qui fait saillie à partir de la paroi latérale 20 du récipient 14 vers l'axe A-A' dans le volume intérieur 26.The securing means 42 of the nozzle 40 on the container 14 comprise, in this example, an inner annular bead 75 which protrudes from the side wall 20 of the container 14 towards the axis A-A 'in the internal volume 26.

La jupe périphérique extérieure 54 du corps 50 est calée vers le haut contre le bourrelet intérieur 75.The outer peripheral skirt 54 of the body 50 is wedged upwardly against the inner bead 75.

Les moyens de protection 44 comprennent une base creuse 80 de réception de l'embout 40 et de la partie inférieure du récipient 14, un obturateur 82 de protection de l'embout 40 dans sa position de repos, monté à demeure sur la base 80, et un organe 84 de sollicitation élastique de l'embout 40 vers sa position de repos.The protection means 44 comprise a hollow base 80 for receiving the end piece 40 and the lower part of the container 14, a shutter 82 for protecting the end piece 40 in its rest position, permanently mounted on the base 80, and a resilient biasing member 84 of the nozzle 40 towards its rest position.

Dans l'exemple représenté sur les Figures 1 à 3, les moyens de protection 44 comprennent en outre un capot 86 de protection monté de manière amovible sous la base creuse 80.In the example shown on the Figures 1 to 3 , the protection means 44 further comprise a cover 86 of protection mounted removably under the hollow base 80.

La base creuse 80 comprend une paroi supérieure 90 de guidage du récipient 14 et de l'embout 40, une jupe périphérique inférieure 92 de protection propre à faire obstacle au contact entre une surface corporelle de l'utilisateur et l'embout 40, et une butée intérieure annulaire 94 de guidage du déplacement de l'embout 40.The hollow base 80 comprises an upper wall 90 for guiding the container 14 and the end piece 40, a lower peripheral skirt 92 for protecting it. obstacle to the contact between a body surface of the user and the tip 40, and an annular inner stop 94 for guiding the displacement of the tip 40.

Dans l'exemple représenté sur les Figures, la paroi supérieure 90, la jupe inférieure 92 et la butée intérieure 94 sont réalisées d'un seul tenant en étant venues de matière.In the example shown in the figures, the upper wall 90, the lower skirt 92 and the inner abutment 94 are made in one piece by being made of material.

La paroi supérieure 90 est de forme sensiblement cylindrique d'axe A-A'. Elle présente une section intérieure de forme complémentaire à la section extérieure du récipient 14.The upper wall 90 is substantially cylindrical in shape of axis A-A '. It has an inner section of complementary shape to the outer section of the container 14.

La paroi supérieure 90 fait saillie vers le haut à partir du bord périphérique extérieur de la butée intérieure 94 jusqu'à un bord libre 96 situé au-dessus du col 24. Elle délimite intérieurement un espace 98 d'insertion et de guidage de la partie inférieure du récipient 14 et de l'embout 40. L'espace 98 débouche vers le haut autour du bord libre 96 et est partiellement obturé vers le bas par la butée intérieure 94.The upper wall 90 projects upwardly from the outer peripheral edge of the inner abutment 94 to a free edge 96 located above the neck 24. It defines internally a space 98 for insertion and guiding the part The space 98 opens upwards around the free edge 96 and is partially closed downwards by the internal stop 94.

Le récipient 14 est reçu mobile à coulissement le long de l'axe A-A' dans l'espace intérieur 98, en étant guidé par la coopération entre la paroi supérieure 90 de la base creuse 80 et la paroi latérale 20.The container 14 is slidably received along the axis A-A 'in the interior space 98, being guided by the cooperation between the upper wall 90 of the hollow base 80 and the side wall 20.

La butée intérieure 94 fait saillie radialement vers l'axe A-A' entre la paroi supérieure 90 et la jupe 92. Elle délimite une ouverture centrale 100 de forme sensiblement complémentaire à celle de l'obturateur 82.The inner abutment 94 protrudes radially towards the axis A-A 'between the upper wall 90 and the skirt 92. It delimits a central opening 100 of shape substantially complementary to that of the shutter 82.

L'étendue radiale de l'ouverture centrale 100 autour de l'axe A-A' est inférieure à l'étendue radiale de l'espace 98. L'ouverture centrale 100 débouche vers le haut dans l'espace 98.The radial extent of the central opening 100 about the axis A-A 'is smaller than the radial extent of the space 98. The central opening 100 opens upwards in the space 98.

La butée 94 délimite en outre, autour de l'ouverture centrale 100, une surface supérieure 102 de butée de l'obturateur 82 et de l'organe de sollicitation 84, comme on va le décrire plus bas. La surface supérieure 102 s'étend sensiblement dans un plan transversal par rapport à l'axe A-A'.The stop 94 further delimits, around the central opening 100, an upper surface 102 for abutment of the shutter 82 and the biasing member 84, as will be described below. The upper surface 102 extends substantially in a plane transverse to the axis A-A '.

La jupe de protection 92 fait saillie vers le bas sous la butée 94, autour et à l'écart transversalement de l'embout 40, jusqu'à un bord inférieur libre 104 s'étendant transversalement par rapport à l'axe A-A'.The protective skirt 92 projects downwards under the abutment 94, around and transversely away from the end piece 40, to a free lower edge 104 extending transversely with respect to the axis A-A ' .

Dans cet exemple, la jupe de protection 92 est pleine sur toute sa périphérie. Dans une variante, la jupe 92 est partiellement ajourée. Elle comprend alors des ouvertures pouvant s'étendre jusqu'au bord libre 104.In this example, the protective skirt 92 is full over its entire periphery. In a variant, the skirt 92 is partially openwork. It then comprises openings that can extend to the free edge 104.

Dans tous les cas, la jupe 92 délimite intérieurement une cavité 106 de protection de l'embout 40 dans laquelle sont disposés l'extrémité inférieure de l'embout 40 et l'orifice de distribution 74 dans la position de pré-distribution et dans la position de distribution.In all cases, the skirt 92 internally defines a cavity 106 for protecting the tip 40 in which the lower end of the tip 40 and the dispensing orifice 74 are positioned in the pre-distribution position and in the distribution position.

La cavité de protection 106 débouche vers le haut dans l'ouverture centrale 100. Elle présente une étendue radiale, prise autour de l'axe A-A' supérieure à celle de l'ouverture centrale 100.The protective cavity 106 opens upwards in the central opening 100. It has a radial extent, taken around the axis A-A 'greater than that of the central opening 100.

La cavité de protection 106 débouche vers le bas par une ouverture 108 inférieure de passage de produit s'étendant en regard de l'orifice 74 dans la position de distribution de produit.The protective cavity 106 opens downwards through a lower opening of product passage 108 extending opposite the orifice 74 in the product dispensing position.

La section transversale de l'ouverture de passage 108 est supérieure, avantageusement au moins deux fois supérieure, à la section transversale de l'embout 40 et à la section transversale de l'orifice de distribution 74.The cross section of the passage opening 108 is greater, advantageously at least twice, greater than the cross section of the tip 40 and the cross section of the dispensing orifice 74.

La hauteur h1 de la jupe 92 et de la cavité de protection 106, prise parallèlement à l'axe A-A' entre le bord inférieur libre 104 et la sortie de l'ouverture centrale 100 est supérieure à au moins deux fois la distance d1 séparant l'extrémité inférieure de l'ouverture centrale 100 de l'orifice de distribution 74 dans la position de distribution représentée sur la Figure 5.The height h1 of the skirt 92 and the protective cavity 106, taken parallel to the axis AA 'between the free lower edge 104 and the outlet of the central opening 100 is greater than at least twice the distance d1 between lower end of the central opening 100 of the dispensing orifice 74 in the dispensing position shown in FIG. Figure 5 .

La hauteur de la jupe 92 est par ailleurs supérieure à au moins deux fois la course maximale de l'embout 40 le long de l'axe A-A' entre sa position de repos représentée sur la Figure 3 et sa position de distribution de produit représentée sur la Figure 5.The height of the skirt 92 is also greater than at least twice the maximum stroke of the nozzle 40 along the axis AA 'between its rest position represented on the Figure 3 and its product distribution position shown on the Figure 5 .

De même, dans la position de distribution et dans la position de pré-distribution, la distance séparant l'orifice de distribution 74 de l'ouverture de distribution 108 définie par la jupe 92 est supérieure à deux fois l'étendue transversale de l'orifice de distribution 74. Cette distance est aussi supérieure à la longueur de l'embout 40 qui fait saillie dans la cavité 106, prise le long de l'axe A-A' de l'embout 40.Likewise, in the dispensing position and in the pre-dispensing position, the distance separating the dispensing orifice 74 from the dispensing opening 108 defined by the skirt 92 is greater than twice the transverse extent of the dispensing orifice. dispensing orifice 74. This distance is also greater than the length of the nozzle 40 which projects into the cavity 106, taken along the axis AA 'of the nozzle 40.

La distance séparant l'orifice de distribution 74 de l'ouverture de distribution 108 dans la position de distribution est avantageusement supérieure ou égale à 0,4 fois, avantageusement à la moitié de l'étendue transversale maximale de l'ouverture de passage 108. Par exemple, pour un diamètre d'ouverture égale à 50 mm, la distance est égale à 25 mm.The distance separating the dispensing orifice 74 from the dispensing opening 108 in the dispensing position is advantageously greater than or equal to 0.4 times, advantageously at half the maximum transverse extent of the passage opening 108. For example, for an opening diameter of 50 mm, the distance is equal to 25 mm.

Ainsi, dans une utilisation normale du dispositif 10, en conservant l'axe A-A' sensiblement vertical et le distributeur 16 en dessous du récipient 14, la jupe 92 est propre à créer un obstacle au contact accidentel ou volontaire entre une surface corporelle de l'utilisateur et l'orifice de distribution 74.Thus, in a normal use of the device 10, keeping the axis AA 'substantially vertical and the distributor 16 below the container 14, the skirt 92 is able to create an obstacle to accidental or deliberate contact between a body surface of the user and dispensing orifice 74.

En outre, la jupe 92 fait obstacle au contact accidentel entre la surface de réception 18, qui peut avoir été contaminée préalablement, et l'embout 40.In addition, the skirt 92 prevents the accidental contact between the receiving surface 18, which may have been contaminated beforehand, and the tip 40.

Dans cet exemple, l'obturateur 82 et l'organe de sollicitation 84 sont réalisés d'un seul tenant en étant venus de matière. En variante, ces éléments sont formés par deux pièces distinctes.In this example, the shutter 82 and the biasing member 84 are made in one piece by being made of material. Alternatively, these elements are formed by two separate parts.

L'obturateur 82 comprend une collerette supérieure 110 de retenue, une base tubulaire 112 reçue dans l'ouverture centrale 100 et une pluralité de pétales 114 déformables entre une configuration fermée d'obturation du volume situé sous l'embout 40 et une configuration ouverte de dégagement du volume situé sous l'embout 40.The shutter 82 comprises an upper retaining collar 110, a tubular base 112 received in the central opening 100 and a plurality of petals 114 which are deformable between a closed volume closure configuration located under the endpiece 40 and an open configuration of FIG. release of the volume located under the tip 40.

La collerette de retenue 110 est appliquée contre la surface supérieure 102 de la butée 94 dans l'espace 98. Elle empêche le déplacement axial global vers le bas de l'obturateur 82 lors du déplacement vers le bas de l'embout 40.The retaining flange 110 is applied against the upper surface 102 of the abutment 94 in the space 98. It prevents the overall axial displacement downward of the shutter 82 during the downward displacement of the endpiece 40.

La paroi de base 112 présente une surface extérieure de section sensiblement égale à celle de l'ouverture intérieure 100 et une section intérieure de forme sensiblement complémentaire à celle du manchon 58 en regard de la valve 52, de manière à obtenir un assemblage coulissant.The base wall 112 has an outer surface of section substantially equal to that of the inner opening 100 and an inner section of substantially complementary shape to that of the sleeve 58 facing the valve 52, so as to obtain a sliding assembly.

Les pétales 114 font saillie vers le bas dans la cavité de protection 106.The petals 114 protrude down into the protective cavity 106.

Les pétales 114 sont déformables entre la configuration fermée de l'obturateur 82 empêchant d'accéder à l'embout 40 depuis l'extérieur à travers la cavité de protection 106 et la configuration ouverte de passage de l'embout 40.The petals 114 are deformable between the closed configuration of the shutter 82 preventing access to the tip 40 from the outside through the protective cavity 106 and the open configuration of passage of the tip 40.

Dans la configuration fermée représentée sur la Figure 2, les pétales 114 présentent chacun une forme de portion de dôme convergeant vers l'axe A-A'.In the closed configuration shown on the Figure 2 the petals 114 each have a dome-shaped portion converging on the axis A-A '.

Chaque bord latéral d'un pétale 114 est alors en contact ou à proximité d'un bord latéral d'un pétale 114 adjacent. Les extrémités libres des pétales 114 sont au contact ou à proximité les unes des autres, de sorte que l'obturateur 82 présente sensiblement une forme de dôme inversé.Each side edge of a petal 114 is then in contact with or near a side edge of an adjacent petal 114. The free ends of the petals 114 are in contact or close to each other, so that the shutter 82 has substantially an inverted dome shape.

Dans la configuration ouverte, les pétales 114 ont été écartés de l'axe A-A' pour être inscrits sensiblement dans un cylindre d'un axe A-A'.In the open configuration, the petals 114 have been separated from the axis A-A 'to be inscribed substantially in a cylinder of an axis A-A'.

Les extrémités libres des pétales 114 se sont écartées les unes des autres à l'écart de l'axe A-A'. Les pétales 114 délimitent entre eux un passage central de circulation de l'embout 40 à travers l'obturateur qui débouche vers le haut et vers le bas.The free ends of the petals 114 are spaced from each other away from the axis A-A '. The petals 114 delimit between them a central passage of circulation of the tip 40 through the shutter which opens upwards and downwards.

Dans l'exemple représenté sur les Figures 1 à 6, l'organe de sollicitation 84 est formé par un ressort hélicoïdal 120 interposé entre l'embout 40 et la butée 94 dans l'espace de circulation 98.In the example shown on the Figures 1 to 6 , the biasing member 84 is formed by a helical spring 120 interposed between the tip 40 and the stop 94 in the circulation space 98.

Le ressort 120 présente une extrémité supérieure calée axialement entre l'épaulement 66 et le jonc 68, pour être déplaçable axialement avec l'embout 40. Il présente une extrémité inférieure calée sur la collerette 102 pour rester sensiblement immobile axialement sur la butée 94 lors du déplacement axial de l'embout 40.The spring 120 has an upper end wedged axially between the shoulder 66 and the rod 68, to be axially displaceable with the endpiece 40. It has a lower end wedged on the collar 102 to remain substantially stationary axially on the stop 94 during the axial displacement of the tip 40.

Le ressort 120 est propre à se comprimer axialement pour engendrer une force de sollicitation de l'embout 40 vers sa position supérieure de repos.The spring 120 is capable of compressing axially to generate a biasing force of the nozzle 40 to its upper rest position.

Le capot 86 est monté de manière amovible autour du bord libre 104 de la jupe de protection 92 pour obturer temporairement la cavité 106. Il est déplaçable manuellement par l'utilisateur du dispositif à l'écart de l'a jupe de protection 92 pour permettre de dégager l'ouverture inférieure 108.The cover 86 is removably mounted around the free edge 104 of the protective skirt 92 to temporarily seal the cavity 106. It is manually movable by the user of the device away from the protective skirt 92 to allow to clear the lower opening 108.

Le fonctionnement du premier dispositif 10 selon l'invention va maintenant être décrit.The operation of the first device 10 according to the invention will now be described.

Initialement, le volume intérieur 26 contient du produit cosmétique confiné vers le haut sous le piston suiveur 28, confiné latéralement par la paroi latérale 20, et confiné vers le bas par la valve 52 de l'embout d'obturation 40.Initially, the interior volume 26 contains cosmetic product confined upwardly under the follower piston 28, confined laterally by the side wall 20, and confined downwards by the valve 52 of the closure cap 40.

L'embout 40 est maintenu dans sa position supérieure de repos (représentée sur les Figures 2 et 3) par l'organe de sollicitation élastique 84.The end piece 40 is held in its upper rest position (shown on the Figures 2 and 3 ) by the resilient biasing member 84.

Dans cette position, la hauteur du récipient 14 insérée dans l'espace 98 est minimale. La paroi de liaison 56 n'est pas déformée significativement et est située relativement à l'écart de la butée 94.In this position, the height of the container 14 inserted into the space 98 is minimal. The connecting wall 56 is not significantly deformed and is located relatively to the distance from the abutment 94.

L'obturateur 82 occupe sa configuration fermée en forme de dôme. L'orifice de distribution 74 est situé au-dessus de l'obturateur 82 sensiblement en regard de la butée 94.The shutter 82 occupies its closed domed configuration. The dispensing orifice 74 is located above the shutter 82 substantially opposite the abutment 94.

La valve 52 est au repos, et l'orifice de distribution 74 est obturé pour empêcher le passage de produit cosmétique 20 vers le bas.The valve 52 is at rest, and the dispensing orifice 74 is closed to prevent the passage of cosmetic product 20 downwards.

Le capot amovible 86 est monté autour du bord libre 104 de la jupe 92 pour limiter encore l'accès à la cavité 106.The removable cover 86 is mounted around the free edge 104 of the skirt 92 to further limit access to the cavity 106.

La distance entre la paroi inférieure 72 de la valve 52 et le bord libre 104 inférieur de la jupe 92 est maximale.The distance between the lower wall 72 of the valve 52 and the free edge 104 of the skirt 92 is maximal.

Puis, l'utilisateur retire le capot 86 pour dégager l'accès à la cavité 106 et le volume situé axialement sous l'obturateur 82. L'utilisateur appuie alors sur le récipient 14 en exerçant une force de poussée vers le bas le long de l'axe A-A'. Ceci provoque le déplacement relatif le long de l'axe A-A' du récipient 14 et de l'embout 40 par rapport aux moyens de protection 44, pour faire passer l'embout 40 de sa position de repos à sa position de pré-distribution, représentée sur la Figure 4.Then, the user removes the cover 86 to clear the access to the cavity 106 and the volume located axially under the shutter 82. The user then presses the container 14 by exerting a pushing force down along the axis A-A '. This causes the relative displacement along the axis AA 'of the container 14 and the tip 40 relative to the protection means 44, to move the tip 40 from its rest position to its pre-distribution position, represented on the Figure 4 .

Lors de ce déplacement, le récipient 14 coulisse le long de l'axe A-A' vers le bas dans la paroi supérieure de guidage 90. L'embout 40 se déplace vers le bas en comprimant les moyens de sollicitation 84 entre l'épaulement extérieur 66 et la collerette 110.During this movement, the container 14 slides along the axis AA 'downwards in the upper guide wall 90. The tip 40 moves downwards by compressing the biasing means 84 between the outer shoulder 66 and the flange 110.

Le manchon 58 entre alors en contact avec les pétales 114 et les écarte à l'écart de l'axe A-A'. L'obturateur 82 passe ainsi dans sa configuration ouverte.The sleeve 58 then comes into contact with the petals 114 and spreads them away from the axis A-A '. The shutter 82 thus passes in its open configuration.

La valve 52 est alors disposée au moins partiellement en saillie vers le bas dans la cavité de protection 106, tout en restant relativement au-dessus du bord libre 104, afin de limiter le risque de contact entre une surface corporelle de l'utilisateur et l'embout 40.The valve 52 is then disposed at least partially projecting downward into the protective cavity 106, while remaining relatively above the free edge 104, in order to limit the risk of contact between a body surface of the user and the patient. tip 40.

Dans la position de pré-distribution, la valve 52 reste fermée et l'orifice de distribution 74 reste obturé.In the pre-dispensing position, the valve 52 remains closed and the dispensing orifice 74 remains closed.

Le volume situé axialement vers le bas au dessous de l'orifice de distribution 74 est totalement dégagé. La jupe 92 est néanmoins interposée entre la surface de réception 18 et l'orifice 74 pour faire obstacle au contact entre cette surface 18 et l'orifice 74.The volume located axially downward below the dispensing orifice 74 is completely clear. The skirt 92 is nevertheless interposed between the receiving surface 18 and the orifice 74 to prevent the contact between this surface 18 and the orifice 74.

Ensuite, comme représenté sur la Figure 5, l'utilisateur continue à déplacer le récipient 14 vers le distributeur 16 pour augmenter encore la hauteur du récipient 14 introduite dans l'espace 98.Then, as shown on the Figure 5 , the user continues to move the container 14 to the dispenser 16 to further increase the height of the container 14 introduced into the space 98.

La force de déformation de l'organe de sollicitation 84 est alors supérieure à la force de déformation de la paroi de liaison déformable 56. La paroi 56 se déforme alors axialement, et son bord inférieur se rapproche de son bord supérieur.The deformation force of the biasing member 84 is then greater than the deformation force of the deformable connecting wall 56. The wall 56 then deforms axially, and its lower edge approaches its upper edge.

Ceci conduit à une diminution du volume intérieur 26 disponible pour recevoir le produit cosmétique, et par suite, à une augmentation de la pression dans le volume intérieur 26 conduisant à l'ouverture de l'orifice de distribution 74.This leads to a decrease in the internal volume 26 available to receive the cosmetic product, and consequently to an increase in the pressure in the internal volume 26 leading to the opening of the dispensing orifice 74.

L'embout 40 reste logé dans la cavité de protection 106, sensiblement à la même distance du bord libre de la jupe 92 que dans la position de pré-distribution.The tip 40 remains housed in the protective cavity 106, substantially at the same distance from the free edge of the skirt 92 as in the pre-distribution position.

L'orifice de distribution 74 s'ouvrant, le produit cosmétique 20 s'écoule par gravité depuis le volume intérieur 26 à travers le canal 60, puis à travers l'orifice 74. Il s'écoule vers le bas dans la cavité de protection 106 et tombe par gravité sur la surface de réception 18 à travers l'ouverture 108, sans rencontrer d'obstacle. Ceci assure que le produit cosmétique ne se dépose pas dans la cavité 106, et limite donc le risque que l'utilisateur insère un doigt dans la cavité 106 pour la nettoyer.With the dispensing orifice 74 opening, the cosmetic product 20 flows by gravity from the internal volume 26 through the channel 60 and then through the orifice 74. It flows downwards into the protective cavity 106 and falls by gravity on the receiving surface 18 through the opening 108, without encountering any obstacle. This ensures that the cosmetic product does not deposit in the cavity 106, and thus limits the risk that the user inserts a finger into the cavity 106 to clean it.

On notera que les moyens de protection 44 sont agencés pour que le produit cosmétique délivré à travers l'embout 40 n'entre pas en contact avec les moyens de protection 44 lorsqu'il est délivré sur la surface 18.It will be noted that the protection means 44 are arranged so that the cosmetic product delivered through the tip 40 does not come into contact with the protection means 44 when it is delivered on the surface 18.

L'utilisateur relâche alors le récipient 14. En l'absence de poussée sur le récipient 14, la paroi de liaison 56 reprend sa forme initiale et l'organe de sollicitation 84 se déploie vers sa configuration de repos. Le récipient 14 et l'embout 40 liés à une extrémité de l'organe 84 remontent alors le long de l'axe A-A' vers la position de repos de l'embout 40.The user then releases the container 14. In the absence of thrust on the container 14, the connecting wall 56 returns to its original shape and the biasing member 84 deploys to its rest configuration. The container 14 and the end piece 40 connected to one end of the member 84 then go up along the axis A-A 'to the rest position of the end piece 40.

Lors de ce déplacement, le piston suiveur 28 se déplace vers le bas sous l'effet de la dépression créée dans le volume intérieur 26.During this movement, the follower piston 28 moves downwards under the effect of the depression created in the interior volume 26.

En outre, les pétales 114 de l'obturateur 82 se rabattent les uns vers les autres dans la configuration fermée pour obturer vers le haut la cavité 106 et empêcher tout contact de la surface 18 ou d'une surface corporelle de l'utilisateur avec l'embout 40, dont l'orifice de distribution 74 est confiné entre l'obturateur 82 et le récipient 14.In addition, the petals 114 of the shutter 82 fold toward each other in the closed configuration to plug the cavity 106 upward and prevent any contact of the surface 18 or of a body surface of the user with the tip 40, whose dispensing orifice 74 is confined between the shutter 82 and the container 14.

Ainsi, dès que la distribution est terminée, l'accès à l'orifice de distribution 74 est totalement empêché, ce qui évite que l'utilisateur touche volontairement ou involontairement l'orifice de distribution 74 et contamine ainsi le produit cosmétique 20 contenu dans le récipient 14.Thus, as soon as the dispensing is complete, access to the dispensing orifice 74 is completely prevented, which prevents the user from voluntarily or involuntarily touching the dispensing orifice 74 and thus contaminates the cosmetic product contained in the dispensing device. container 14.

Une fois le produit cosmétique reçu sur la surface 18, l'utilisateur peut alors l'appliquer sur la surface corporelle, dans le cas où la surface 18 n'est pas une surface corporelle.Once the cosmetic product received on the surface 18, the user can then apply it on the body surface, in the case where the surface 18 is not a body surface.

Dans cet exemple, le récipient 14 est actionné par l'utilisateur pour faire passer l'embout 40 successivement de sa position de repos dans sa position intermédiaire de pré-distribution, puis dans sa position de distribution. Il forme en tant que tel un moyen d'actionnement de la distribution de produit.In this example, the container 14 is actuated by the user to pass the tip 40 successively from its rest position in its intermediate pre-distribution position, then in its dispensing position. It forms as such a means for actuating the product distribution.

Dans une variante (non représentée), le dispositif de distribution 10 est dépourvu d'obturateur 82. Le risque de contamination de l'orifice de distribution 74 reste néanmoins très limité compte tenu de la présence de la jupe 92 qui crée un obstacle pour accéder à l'orifice de distribution 74.In a variant (not shown), the dispensing device 10 is devoid of shutter 82. The risk of contamination of the dispensing orifice 74 is nevertheless very limited given the presence of the skirt 92 which creates an obstacle to access at the dispensing orifice 74.

Un deuxième dispositif 130 selon l'invention est représenté sur les Figures 7 à 12.A second device 130 according to the invention is represented on the Figures 7 to 12 .

A la différence du premier dispositif 10, le col inférieur 24 du récipient 14 est rapporté à l'extrémité inférieure de la paroi latérale 20.Unlike the first device 10, the lower neck 24 of the container 14 is attached to the lower end of the side wall 20.

En outre, les organes de sollicitation 84 et l'obturateur 82 sont formés dans le col inférieur 24.In addition, the biasing members 84 and the shutter 82 are formed in the lower neck 24.

A cet effet, comme illustré par les Figures 8 et 10, le col 24 comprend une paroi périphérique extérieure 132 insérée dans la paroi latérale 20 et une paroi transversale inférieure 134 convergeant radialement vers l'axe A-A' jusqu'à l'obturateur 82.For this purpose, as illustrated by Figures 8 and 10 , the neck 24 comprises an outer peripheral wall 132 inserted into the side wall 20 and a lower transverse wall 134 converging radially towards the axis AA 'to the shutter 82.

Comme illustré par la Figure 7, la paroi extérieure 132 est retenue axialement par rapport à la paroi latérale 20, par l'intermédiaire d'une patte de retenue 134 encliquetée sur un ergot 136 solidaire de la paroi extérieure 132. La paroi extérieure 132 est enserrée entre la patte 136 et la paroi 20.As illustrated by Figure 7 , the outer wall 132 is retained axially relative to the side wall 20, by means of a retaining tab 134 snapped onto a lug 136 integral with the outer wall 132. The outer wall 132 is sandwiched between the lug 136 and the wall 20.

La paroi transversale 134 converge vers le bas jusqu'à un bord supérieur 140 de l'obturateur 82.The transverse wall 134 converges downwardly to an upper edge 140 of the shutter 82.

La paroi transversale 134 délimite une pluralité de fentes 142 en forme d'arc de cercle autour de l'axe A-A'. Chaque fente 142 s'étend entre une extrémité intérieure située sur le bord supérieur 140 de l'obturateur 82 et une extrémité extérieure située au voisinage de la périphérie de la paroi 134.The transverse wall 134 delimits a plurality of slots 142 in the shape of a circular arc around the axis A-A '. Each slot 142 extends between an inner end located on the upper edge 140 of the shutter 82 and an outer end located in the vicinity of the periphery of the wall 134.

Les fentes 142 délimitent entre elles des lames élastiques 148 déformables présentant une extrémité intérieure 144 liée à l'obturateur 82 au niveau du bord supérieur 140 et une extrémité extérieure 146 déplaçable conjointement avec le récipient 14 par rapport à l'extrémité extérieure 144.The slots 142 delimit between them deformable elastic blades 148 having an inner end 144 connected to the shutter 82 at the upper edge 140 and an outer end 146 displaceable together with the container 14 relative to the outer end 144.

Le col 24 est disposé en appui sur la surface supérieure 102 de la butée annulaire 94. Le bord supérieur 140 de l'obturateur 82 et les extrémités intérieures 146 des lames 148 restent solidaires de la surface supérieure 102 lors du déplacement du récipient 14 vers les moyens de protection 44.The neck 24 is placed in abutment on the upper surface 102 of the annular abutment 94. The upper edge 140 of the shutter 82 and the inner ends 146 of the blades 148 remain integral with the upper surface 102 during the displacement of the container 14 towards the means of protection 44.

Dans une variante représentée sur les Figures 7 à 12, le deuxième dispositif 130 diffère en outre du premier dispositif 10 en ce qu'un opercule déchirable 150 est monté à l'extrémité inférieure de l'embout 40 dans sa position de repos initiale, représentée sur la Figure 7, avant la première utilisation du dispositif 130.In a variant shown on the Figures 7 to 12 the second device 130 also differs from the first device 10 in that a tear-off lid 150 is mounted at the lower end of the nozzle 40 in its initial rest position, shown in FIG. Figure 7 before the first use of the device 130.

L'opercule 150 comprend une bague de retenue 152 entourant le manchon 58. La bague 152 est munie d'une collerette 154 appliquée contre le bord supérieur 140 de l'obturateur 82, en appui indirect sur la butée annulaire 94.The cover 150 comprises a retaining ring 152 surrounding the sleeve 58. The ring 152 is provided with a flange 154 applied against the upper edge 140 of the shutter 82, in indirect support on the annular abutment 94.

L'opercule 150 comprend en outre un film frangible 156 obturant vers le bas le canal 60 autour du bord libre, sous l'orifice de distribution 74.The lid 150 further comprises a frangible film 156 closing down the channel 60 around the free edge, under the dispensing orifice 74.

Comme illustré par les Figures 18 et 19, le film frangible 156 est en forme de disque. Il est fixé à sa périphérie sur le bord libre 64 du manchon 58, par une liaison pelable telle qu'un adhésif. Il est fixé de manière plus solide à la bague 152 par l'intermédiaire d'une languette 156A qui raccorde la périphérie du film 156 à la bague 152. Initialement, la languette 156A forme un pli le long du bord périphérique du film 156 et est plaquée sous le film 156.As illustrated by Figures 18 and 19 the frangible film 156 is disk-shaped. It is fixed at its periphery on the free edge 64 of the sleeve 58, by a peelable bond such as an adhesive. It is fixed more securely to the ring 152 by means of a tab 156A which connects the periphery of the film 156 to the ring 152. Initially, the tab 156A forms a fold along the peripheral edge of the film 156 and is plated under the film 156.

Le fonctionnement du deuxième dispositif 130 diffère du fonctionnement du premier dispositif 10 en ce que le déplacement du récipient 14 vers le distributeur 16 provoque la déformation de chaque lame élastique 148 pour amener son extrémité extérieure libre 146, déplaçable conjointement avec le récipient 14, sous son extrémité intérieure 144 liée au bord supérieur 140 de l'obturateur 82.The operation of the second device 130 differs from the operation of the first device 10 in that the displacement of the container 14 towards the distributor 16 causes the deformation of each elastic blade 148 to bring its free outer end 146, movable together with the container 14, under its inner end 144 connected to the upper edge 140 of the shutter 82.

Ainsi, la déformation des lames 148 provoque la création d'une cavité annulaire 158 délimitée latéralement par les lames 148 et intérieurement par la paroi de base 112 de l'obturateur. La butée 94 est reçue partiellement dans la cavité annulaire 158 dans la position de pré-distribution représentée sur la Figure 9.Thus, the deformation of the blades 148 causes the creation of an annular cavity 158 delimited laterally by the blades 148 and internally by the base wall 112 of the shutter. The stop 94 is partially received in the annular recess 158 in the pre-distribution position shown in FIG. Figure 9 .

En outre, le passage de l'embout 40 depuis sa position initiale de repos vers sa position de pré-distribution provoque la remontée de la bague de retenue 152 le long de la surface extérieure du manchon 58, jusqu'à ce que la bague 152 entre en contact avec l'épaulement extérieur 66 défini par le manchon 58. Lors de ce déplacement, la languette 156A, solidaire à une extrémité de la bague 152, tire sur le film 156 qui se détache progressivement du bord 64 du manchon 58 en se retournant sur lui même.In addition, the passage of the tip 40 from its initial rest position to its pre-distribution position causes the retaining ring 152 to rise up along the outer surface of the sleeve 58, until the ring 152 into contact with the outer shoulder 66 defined by the sleeve 58. During this movement, the tongue 156A, secured to one end of the ring 152, pulls on the film 156 which is gradually detached from the edge 64 of the sleeve 58 by turning on itself.

Puis, après le passage de l'embout 40 dans sa position de distribution représentée sur la Figure 11, dans laquelle la paroi de liaison 56 se déforme, la bague 152 remonte conjointement avec le manchon 58 et reste fixe sur l'épaulement 66, lors du retour de l'embout 40 vers le haut jusqu'à sa position de repos, sous l'effet de la paroi de liaison 56.Then, after the passage of the tip 40 in its dispensing position shown on the Figure 11 , in which the connecting wall 56 is deformed, the ring 152 rises together with the sleeve 58 and remains fixed on the shoulder 66, during the return of the nozzle 40 up to its rest position, under the effect of the connecting wall 56.

Un troisième dispositif 160 selon l'invention est représenté sur la Figure 13. A la différence du premier dispositif 10, le récipient 14 est formé par un tube déformable 162 par pincement pour engendrer une pression par diminution du volume intérieur 26.A third device 160 according to the invention is represented on the Figure 13 . Unlike the first device 10, the container 14 is formed by a deformable tube 162 by pinching to generate a pressure by decreasing the internal volume 26.

Le tube 162 est monté fixe par rapport au distributeur 44. Les moyens de protection 44 sont dépourvus d'obturateur 82 et l'embout 40 est monté immobile dans les moyens de protection 44.The tube 162 is fixedly mounted with respect to the dispenser 44. The protection means 44 do not have a shutter 82 and the tip 40 is fixedly mounted in the protection means 44.

Un quatrième dispositif 170 selon l'invention est représenté sur la Figure 14. A la différence du premier dispositif 10, le récipient 14 comprend un boîtier 172 monté fixe par rapport au distributeur 16. Le boîtier 172 comporte un réservoir (non visible) de produit cosmétique et un bouton 174 d'actionnement de la distribution de produit monté mobile par rapport au boîtier 172.A fourth device 170 according to the invention is represented on the Figure 14 . Unlike the first device 10, the container 14 comprises a housing 172 fixedly mounted relative to the dispenser 16. The housing 172 comprises a reservoir (not visible) of cosmetic product and a button 174 for actuating the mobile mounted product distribution relative to the housing 172.

L'actionnement du bouton d'actionnement 174 engendre le déplacement de l'embout 40 depuis sa position de repos vers successivement sa position de pré-distribution et sa position de distribution, et avantageusement l'ouverture de l'obturateur 82, comme décrit précédemment. Le relâchement du bouton 174 permet le retour de l'embout 40 dans sa position de repos.Actuation of the actuating button 174 causes the tip 40 to move from its rest position successively to its pre-distribution position and its dispensing position, and advantageously to open the shutter 82 as previously described. . The release of the button 174 allows the return of the tip 40 in its rest position.

Un cinquième dispositif 180 selon l'invention est représenté sur la Figure 15. A la différence du premier dispositif 10, le récipient 14 est monté rotatif par rapport au distributeur 16 pour actionner la distribution du produit cosmétique 20.A fifth device 180 according to the invention is represented on the Figure 15 . Unlike the first device 10, the container 14 is rotatably mounted relative to the distributor 16 to actuate the dispensing of the cosmetic product 20.

Le cinquième dispositif 180 est muni d'un mécanisme (non visible) de conversion du mouvement de rotation du récipient 14 en un mouvement de translation de l'embout 40 du récipient 14. La mise en rotation du récipient 14 autour de son axe de rotation provoque successivement le passage de l'embout 40 de sa position de repos, dans sa position de pré-distribution, puis dans sa position de distribution.The fifth device 180 is provided with a mechanism (not visible) for converting the rotational movement of the container 14 into a translation movement of the tip 40 of the container 14. The rotation of the container 14 around its axis of rotation successively causes the passage of the tip 40 from its rest position, in its pre-distribution position, then in its dispensing position.

Un sixième dispositif 190 selon l'invention est représenté sur la Figure 16.A sixth device 190 according to the invention is represented on the Figure 16 .

A la différence du premier dispositif 10, ce dispositif 190 comprend un moteur 192 piloté par un bouton d'actionnement 194. Le moteur 192 est raccordé à l'embout 40 pour assurer, sur pression du bouton d'actionnement 194, le déplacement en translation de l'embout 40 entre sa position de repos, sa position de pré-distribution et sa position de distribution.Unlike the first device 10, this device 190 comprises a motor 192 controlled by an actuating button 194. The motor 192 is connected to the endpiece 40 to ensure, on pressing the actuating button 194, the displacement in translation. endpiece 40 between its rest position, its pre-distribution position and its dispensing position.

Un septième dispositif 200 de distribution selon l'invention est représenté sur la Figure 17.A seventh distribution device 200 according to the invention is represented on the Figure 17 .

Comme dans le quatrième dispositif 170, le récipient 14 comprend un boîtier 172 fixe par rapport au distributeur 16.As in the fourth device 170, the container 14 comprises a housing 172 fixed with respect to the dispenser 16.

Le boîtier 172 présente deux ouvertures latérales 202 opposées d'accès à des pattes de commande 204 rotatives.The housing 172 has two opposite lateral openings 202 for access to rotary control tabs 204.

Chaque patte 204 est montée rotative dans le boîtier 172 autour d'un axe respectif B-B', C-C', de part et d'autre de l'axe A-A', perpendiculairement à l'axe A-A', entre une position extérieure de repos, et une position enfoncée intérieurement de déplacement de l'embout 40.Each tab 204 is rotatably mounted in the housing 172 about a respective axis B-B ', C-C', on either side of the axis A-A ', perpendicular to the axis A-A' , between an outside rest position, and an internally driven position of displacement of the end piece 40.

Chaque patte 204 présente une surface inférieure biseautée 206 inclinée par rapport à l'axe A-A'. La surface intérieure 206 est propre à coopérer avec une collerette 208 solidaire de l'embout 40 pour convertir le mouvement de rotation des pattes 204 en un mouvement de translation de l'embout 40 entre sa position de repos, sa position de pré-distribution et sa position de distribution.Each tab 204 has a beveled lower surface 206 inclined relative to the axis A-A '. The inner surface 206 is adapted to cooperate with a flange 208 integral with the endpiece 40 to convert the rotational movement of the tabs 204 into a translation movement of the endpiece 40 between its rest position, its pre-distribution position and its distribution position.

Pour utiliser le septième dispositif 200, l'utilisateur pince les pattes 204 à travers les ouvertures latérales 202 en les rapprochant l'une de l'autre vers l'axe A-A'. Ceci provoque le déplacement en translation de l'embout 40 le long de l'axe A-A', comme décrit précédemment.To use the seventh device 200, the user pinches the tabs 204 through the lateral openings 202 by bringing them closer to each other towards the axis A-A '. This causes the displacement in translation of the tip 40 along the axis A-A ', as previously described.

En variante, des moyens de réglage de la température, par exemple des moyens de chauffage ou/et des moyens de refroidissement sont prévus dans le dispositif de distribution, par exemple au niveau de l'embout 40 pour ajuster la viscosité du produit cosmétique distribué.Alternatively, temperature control means, for example heating means and / or cooling means are provided in the dispensing device, for example at the tip 40 to adjust the viscosity of the dispensed cosmetic product.

Dans d'autres variantes non représentées, l'obturateur 82 est formé par un rideau, un volet, un diaphragme, une guillotine, ou un éventail.In other variants not shown, the shutter 82 is formed by a curtain, a shutter, a diaphragm, a guillotine, or a fan.

En variante encore, le récipient 14 est monté de manière amovible, par exemple par vissage ou par encliquetage dans le distributeur 16. Une fois le produit cosmétique contenu dans le récipient 14 consommé, il est possible de démonter le récipient vide du distributeur et de monter un récipient 14 plein de produit à la place.In another variant, the container 14 is removably mounted, for example by screwing or snapping into the dispenser 16. Once the cosmetic product contained in the container 14 has been consumed, it is possible to remove the empty container from the dispenser and to mount a container 14 full of product instead.

Un nécessaire de distribution de produit cosmétique comportant un récipient 14 amovible, un distributeur 16 tel que défini plus haut, avantageusement contenu dans un emballage peut alors être fourni à l'utilisateur.A cosmetic product distribution kit comprising a removable container 14, a dispenser 16 as defined above, advantageously contained in a package can then be provided to the user.

Le terme « un » doit s'entendre comme « au moins un » sauf si le contraire est précisé.The term "one" must be understood as "at least one" unless the opposite is specified.

Il ressort naturellement de la description ci-dessus et des figures jointes que les orientations relatives des caractéristiques structurelles du dispositif sont celles qui résultent de l'utilisation normale du dispositif, notamment dans la position de pré-distribution et dans la position de distribution. Ces orientations s'entendent en particulier en référence à une disposition du distributeur 16 en dessous du récipient 14, en maintenant l'axe A-A' du récipient 14 et avantageusement de l'embout 40, sensiblement vertical, et à une disposition de la surface de réception 18 en dessous de l'embout 40.It follows naturally from the above description and the attached figures that the relative orientations of the structural characteristics of the device are those which result from the normal use of the device, especially in the pre-distribution position and in the dispensing position. These orientations are understood in particular with reference to an arrangement of the dispenser 16 below the container 14, keeping the axis AA 'of the container 14 and advantageously of the tip 40, substantially vertical, and at a disposal of the surface of receiving 18 below the tip 40.

L'axe A-A' est notamment perpendiculaire au plan moyen du bord libre 104 de la jupe 92 et avantageusement, au plan moyen de l'orifice de distribution 74.The axis A-A 'is in particular perpendicular to the mean plane of the free edge 104 of the skirt 92 and advantageously to the mean plane of the dispensing orifice 74.

Ainsi, dans cette configuration, l'ouverture de passage 108 est disposée au dessous de l'embout 40 en se déplaçant vers le bas suivant l'axe A-A'. L'ouverture de passage 108 est en outre située à l'écart, à une distance non nulle le long de l'axe A-A', de l'orifice de distribution 74, au moins dans la position de pré-distribution et dans la position de distribution.Thus, in this configuration, the passage opening 108 is disposed below the nozzle 40 by moving down the axis A-A '. The passage opening 108 is furthermore located at a non-zero distance along the axis A-A 'of the dispensing orifice 74, at least in the pre-dispensing position and in the distribution position.

Le volume situé sous l'embout 40 est notamment celui engendré le long de l'axe A-A' sous l'orifice de distribution 74.The volume located under the nozzle 40 is in particular that generated along the axis A-A 'under the dispensing orifice 74.

Dans la position de distribution, le produit cosmétique délivré par l'orifice de distribution 74 peut donc s'écouler verticalement vers le bas sous l'effet de la gravité à partir de l'embout 40, à travers le volume situé sous l'embout 40, et atteindre ainsi la surface de réception 18.In the dispensing position, the cosmetic product delivered by the dispensing orifice 74 can therefore flow vertically downwards under the effect of gravity from the nozzle 40, through the volume located under the nozzle. 40, and thus reach the receiving surface 18.

Suivant cette orientation, l'obturateur 82 présente donc bien une configuration fermée, dans laquelle il obture le volume situé sous l'embout 40, et une configuration ouverte, dans laquelle le volume situé sous l'embout 40 est dégagé, notamment sous l'orifice de distribution 74.According to this orientation, the shutter 82 thus has a closed configuration, in which it closes the volume located under the nozzle 40, and an open configuration, in which the volume located under the nozzle 40 is disengaged, in particular under the dispensing orifice 74.

On notera que le passage de l'embout 40 depuis sa position de pré-distribution vers sa position de distribution s'effectue exclusivement lorsque l'obturateur 82 occupe sa configuration ouverte. Ainsi, le produit cosmétique délivré par l'embout 40 dans la position de distribution n'entre pas en contact avec l'obturateur 82, ce qui évite toute contamination microbienne au niveau de l'obturateur 82.Note that the passage of the tip 40 from its pre-distribution position to its dispensing position occurs exclusively when the shutter 82 is in its open configuration. Thus, the cosmetic product delivered by the tip 40 in the dispensing position does not come into contact with the shutter 82, which avoids any microbial contamination at the shutter 82.

Il ressort également que l'embout 40 peut être mobile, notamment en translation par rapport aux moyens de protection 44. En variante, l'embout 40 peut être immobile, notamment en translation, par rapport aux moyens de protection 44, l'obturateur 82 passant alors de sa configuration ouverte à sa configuration fermée sans mouvement de l'embout 40.It also appears that the end piece 40 can be mobile, in particular in translation relative to the protection means 44. In a variant, the end piece 40 can be stationary, in particular in translation, with respect to the protection means 44, the shutter 82 then passing from its open configuration to its closed configuration without movement of the tip 40.

Comme on l'a vu plus haut, les moyens de protection 44 font obstacle au contact entre une surface corporelle d'un utilisateur du distributeur 16 et l'orifice de distribution 74. Cette surface corporelle peut être la surface de réception sur laquelle le produit cosmétique est destiné à être appliqué, ou une autre surface corporelle susceptible d'entrer accidentellement ou volontairement avec le dispositif, notamment dans le cas où la surface de réception 18 est délimitée dans un réceptacle.As has been seen above, the protection means 44 prevent contact between a body surface of a user of the dispenser 16 and the dispensing orifice 74. This body surface may be the receiving surface on which the product cosmetic is intended to be applied, or another body surface likely to enter accidentally or voluntarily with the device, in particular in the case where the receiving surface 18 is delimited in a receptacle.
