Description

La présente invention concerne l'application d'un produit cosmétique ou de soin, notamment sur les lèvres ou les paupières.The present invention relates to the application of a cosmetic or care product, in particular on the lips or the eyelids.

Il est connu de floquer les embouts d'application afin de permettre à ceux-ci de retenir plus de produit et d'accroître le confort au moment de l'application.It is known to flock the application tips to allow them to retain more product and increase comfort at the time of application.

Par exemple, le brevet US 4 772 148 décrit un embout floqué permettant l'application d'un produit.For example, US Patent 4,772,148 discloses a flocked tip for application of a product.

Pour réaliser un embout floqué, il est connu de déposer dans un premier temps un adhésif sur celui-ci puis, dans un deuxième temps, des poils de faible longueur par voie électrostatique.To make a flocked tip, it is known to firstly deposit an adhesive thereon and then, secondly, short length hairs electrostatically.

Il est difficile d'obtenir un revêtement de flocage ayant un contour net.It is difficult to obtain a flocking coating having a sharp outline.

Or, l'absence de contour net est gênante sur le plan esthétique et rend plus difficile l'obtention d'un maquillage soigné.However, the absence of clear outline is inconvenient aesthetically and makes it more difficult to obtain a neat makeup.

L'invention vise notamment à résoudre le problème mentionné ci-dessus.The invention aims in particular to solve the problem mentioned above.

La présente invention a ainsi pour objet un embout qui puisse être fabriqué aisément, qui soit capable de définir une surface d'application convenant à la réalisation d'un maquillage soigné et qui soit confortable à utiliser.The present invention thus relates to a tip that can be easily manufactured, which is capable of defining an application surface suitable for producing a neat makeup and is comfortable to use.

L'embout selon l'invention est tel que défini dans la revendication 1.The tip according to the invention is as defined in claim 1.

Il faut entendre par portions de bord sensiblement au contact des portions de bord se touchant ou étant au voisinage immédiat l'une de l'autre, compte tenu des tolérances de fabrication.Edge portions are understood to be substantially in contact with edge portions touching or being in the immediate vicinity of each other, taking into account manufacturing tolerances.

L'invention permet d'obtenir un revêtement de flocage ayant un contour net, ce qui contribue à l'esthétique de l'embout et permet d'améliorer la qualité du maquillage.The invention makes it possible to obtain a flocking coating having a net contour, which contributes to the aesthetics of the mouthpiece and improves the quality of makeup.

De plus, l'utilisation de deux parties assemblées facilite la réalisation du revêtement de flocage puisque l'une desdites parties peut être floquée séparément plus aisément, avec éventuellement un risque moindre de bouchage du ou des orifices servant à l'alimentation en produit par le revêtement de flocage.In addition, the use of two assembled parts facilitates the realization of the flocking coating since one of said parts can be separately flocked more easily, with possibly a lower risk of clogging the orifices used for the supply of product by the flocking coating.

Dans une réalisation particulière, la deuxième partie comporte un revêtement de flocage s'étendant au moins jusqu'à une portion de bord de ladite deuxième partie, cette portion de bord étant sensiblement au contact d'une portion de bord correspondante, non floquée, de la première partie, la portion de bord de la deuxième partie étant définie par une arête.In a particular embodiment, the second portion comprises a flocking coating extending at least as far as an edge portion of said second portion, this edge portion being substantially in contact with a corresponding, unflocked edge portion of the first part, the edge portion of the second part being defined by an edge.

La deuxième partie peut comporter une ou plusieurs gorges ou cavités et être recouverte par un revêtement de flocage s'étendant sur une partie au moins de la surface intérieure desdites gorges ou cavités.The second part may have one or more grooves or cavities and be covered by a flocking coating extending over at least a portion of the inner surface of said grooves or cavities.

Avantageusement, le ou les orifices par lequel ou lesquels les passages d'amenée du produit débouchent dans le fond de la ou desdites gorges ou cavités se situent en retrait de la surface d'application d'une distance d'au moins 1 mm.Advantageously, the orifice (s) through which the product feedthrough passages open into the bottom of the one or more grooves or cavities are set back from the application surface by a distance of at least 1 mm.

La ou les gorges ou cavités peuvent être floquées sur une partie de leur hauteur à partir de la surface d'application sans craindre que le revêtement de flocage ne gêne outre mesure l'écoulement du produit, car la ou les gorges ou cavités en question peuvent être relativement larges, deux bords opposés étant par exemple distants de plus de 1 mm, la distance entre lesdits bords étant de préférence choisie de telle sorte que la surface des lèvres ou de la peau puisse atteindre le produit contenu à l'intérieur.The groove or grooves may be flocked over part of their height from the application surface without fear that the flocking coating will unduly impede the flow of the product, because the groove or grooves in question can be relatively wide, two opposite edges being for example more than 1 mm apart, the distance between said edges being preferably chosen so that the surface of the lips or the skin can reach the product contained therein.

La présence de la ou des gorges ou cavités est également avantageuse en ce qu'elle peut permettre d'absorber du produit présent en excès sur la surface d'application et d'éviter que le produit ne soit chassé hors de la surface d'application lorsque l'embout est amené au contact de la surface à maquiller ou à traiter.The presence of the groove (s) or cavities is also advantageous in that it can make it possible to absorb excess product present on the application surface and to prevent the product from being driven out of the application surface. when the tip is brought into contact with the surface to be made up or treated.

Dans une réalisation particulière, la deuxième partie se présente sous la forme d'un manchon, recouvert par un revêtement de flocage sur une face frontale et l'une au moins de ses surfaces latérales intérieure et extérieure, de préférence la totalité de sa surface latérale extérieure et une partie de sa surface latérale intérieure.In a particular embodiment, the second portion is in the form of a sleeve, covered by a flocking coating on a front face and at least one of its inner and outer side surfaces, preferably the entire of its lateral surface. outside and part of its inner side surface.

La deuxième partie peut être réalisée dans une matière souple.The second part can be made of a flexible material.

Dans une réalisation particulière, le revêtement de flocage s'étend jusqu'à un bord présentant des ondulations.In a particular embodiment, the flocking coating extends to an edge having corrugations.

Dans une réalisation particulière, la deuxième partie comporte une partie centrale et une partie périphérique reliées par des ponts de matière.In a particular embodiment, the second portion comprises a central portion and a peripheral portion connected by material bridges.

Ces ponts de matière peuvent être non floqués, notamment s'ils se situent nettement en retrait de la surface d'application.These bridges of material may be non-flocked, especially if they are clearly set back from the application surface.

La deuxième partie peut également être floquée en totalité.The second part can also be flocked in full.

Dans une réalisation particulière, l'embout comporte au moins un orifice excentré, pour l'alimentation en produit de la surface d'application.In a particular embodiment, the nozzle comprises at least one eccentric orifice for supplying the product of the application surface.

Dans une réalisation particulière, la deuxième partie est décentrée par rapport à la première, ce qui permet de réaliser le cas échéant un embout plus ergonomique.In a particular embodiment, the second part is off-center with respect to the first, which makes it possible, if necessary, to make a more ergonomic endpiece.

La deuxième partie peut ménager avec la première un espace permettant une circulation, voire une recirculation, du produit sous la deuxième partie.The second part can provide with the first a space for circulation or recirculation of the product under the second part.

L'invention a encore pour objet un dispositif de conditionnement et d'application caractérisé par le fait qu'il comporte un embout tel que défini plus haut et un réservoir de produit pour contenir le produit destiné à alimenter l'embout.The invention further relates to a packaging device and application characterized in that it comprises a nozzle as defined above and a product reservoir for containing the product for feeding the tip.

Le réservoir peut être formé par un corps réalisé d'un seul tenant avec la première partie de l'embout.The reservoir can be formed by a body made in one piece with the first part of the tip.

Le dispositif peut comporter un piston pour exercer une pression sur le produit contenu dans le réservoir en vue de sa distribution.The device may include a piston for exerting pressure on the product contained in the reservoir for distribution.

Le réservoir peut également comporter une paroi compressible permettant de distribuer le produit au moyen d'une pression exercée dessus, par exemple par l'utilisateur.The reservoir may also comprise a compressible wall for dispensing the product by means of a pressure exerted on it, for example by the user.

Le dispositif peut encore comporter une pompe.The device may further comprise a pump.

Le réservoir peut être amovible, et constituer alors une recharge.The tank can be removable, and then constitute a refill.

Lorsque le dispositif comporte une pompe, le réservoir est avantageusement déplaçable par rapport au reste du dispositif de manière à actionner la pompe et à distribuer une dose de produit.When the device comprises a pump, the reservoir is advantageously displaceable relative to the rest of the device so as to actuate the pump and to dispense a dose of product.

Avantageusement, le dispositif comporte un capuchon de fermeture comprenant au moins un élément d'obturation intérieur apte à recouvrir un ou plusieurs orifices de sortie du produit de l'embout lorsqu'il est en place sur celui-ci.Advantageously, the device comprises a closure cap comprising at least one inner closure member capable of covering one or more outlet orifices of the product of the nozzle when it is in place thereon.

L'invention a encore pour objet un procédé de fabrication d'un embout tel que défini plus haut, caractérisé par le fait que la deuxième partie est réalisée avec un revêtement de flocage et au moins une gorge ou cavité sans perçage de cette gorge ou cavité après flocage ni insertion d'un insert dans ladite gorge ou cavité pendant le flocage.The invention also relates to a method of manufacturing a nozzle as defined above, characterized in that the second part is made with a flocking coating and at least one groove or cavity without drilling this groove or cavity after flocking or insertion of an insert into said groove or cavity during flocking.

Ainsi, la fabrication de l'embout est relativement simple.Thus, the manufacture of the tip is relatively simple.

De plus, en évitant de percer la deuxième partie après la réalisation du flocage on empêche la formation de rugosités de surface ou d'amorces de décollement du revêtement de flocage, notamment lorsque la deuxième partie est souple, car réalisée par exemple en élastomère.Moreover, by avoiding piercing the second part after flocking is prevented the formation of surface roughness or primer flocking of the flocking coating, especially when the second part is flexible, because performed by example elastomer.

On a représenté sur la figure 1 un dispositif 10 de conditionnement et d'application comprenant un embout 11 pour l'application du produit, un corps 18 définissant un réservoir 12 contenant un produit P cosmétique ou de soin et un mécanisme 13 permettant de provoquer la distribution d'une dose de produit.FIG. 1 shows a device 10 for packaging and application comprising a tip 11 for the application of the product, a body 18 defining a reservoir 12 containing a cosmetic product P or care and a mechanism 13 for causing the dispensing of a dose of product.

La viscosité du produit P est comprise par exemple entre 0,6 et 17 Pa.s.The viscosity of the product P is for example between 0.6 and 17 Pa.s.

L'embout 11 comporte une première partie ou base 14 sur laquelle est rapportée une deuxième partie ou grille 15, comme cela sera précisé plus loin.The tip 11 has a first portion or base 14 on which is reported a second portion or grid 15, as will be specified below.

Le mécanisme 13 précité comporte une tige filetée 17, tournant dans un perçage du corps 18, capable d'être entraînée en rotation au moyen d'une molette d'entraînement 19 située en partie inférieure du dispositif 10.The aforesaid mechanism 13 comprises a threaded rod 17, rotating in a bore of the body 18, capable of being rotated by means of a driving wheel 19 located in the lower part of the device 10.

Un piston 20 engrène avec la tige 17 et peut se déplacer en translation au contact du corps 18, sans possibilité de rotation relative par rapport à ce dernier, de telle sorte qu'un déplacement de la molette 19 s'accompagne d'un déplacement axial du piston 20 et permette d'expulser une dose de produit à travers un passage 30 prévu en partie supérieure du corps 18.A piston 20 meshes with the rod 17 and can move in translation in contact with the body 18, without the possibility of relative rotation relative to the latter, so that a displacement of the wheel 19 is accompanied by an axial displacement. of the piston 20 and allows to expel a dose of product through a passage 30 provided in the upper part of the body 18.

La base 14 de l'embout 11 est réalisée dans l'exemple décrit d'un seul tenant par moulage de matière plastique avec le corps 18 dans une matière plastique relativement rigide, et comporte une jupe tubulaire 23 entourant un logement 24 dans lequel est fixée la grille 15.The base 14 of the nozzle 11 is made in the example described in one piece by molding plastic material with the body 18 in a relatively rigid plastic material, and comprises a tubular skirt 23 surrounding a housing 24 in which is fixed the grid 15.

C'est donc la base 14 qui sert à l'alimentation de la grille 15 en produit.It is therefore the base 14 which serves to supply the grid 15 with product.

La fixation de la grille 15 sur la base 14 peut s'effectuer de diverses manières sans que l'on sorte du cadre de la présente invention.The attachment of the grid 15 to the base 14 can be carried out in various ways without departing from the scope of the present invention.

Elle peut notamment s'effectuer, comme représenté sur le dessin, au moyen d'un godron 26 réalisé avec la grille 15 et qui vient s'encliqueter de manière étanche dans une gorge annulaire correspondante réalisée sur la surface intérieure de la jupe 23.It can in particular be carried out, as shown in the drawing, by means of a godron 26 made with the grid 15 and which snaps tightly into a corresponding annular groove formed on the inner surface of the skirt 23.

Dans l'exemple décrit, la grille 15 comporte une partie centrale 15a et une partie périphérique 15b, reliées par des ponts de matière 15c.In the example described, the grid 15 comprises a central portion 15a and a peripheral portion 15b, connected by material bridges 15c.

Les parties 15a et 15b ménagent entre elles une gorge annulaire 25 dans laquelle s'étendent les ponts 15c, ces derniers ménageant entre eux des passages par lesquels le produit peut traverser la grille 15.The parts 15a and 15b form between them an annular groove 25 in which the bridges 15c extend, the latter providing between them passages through which the product can pass through the grid 15.

La grille 15 comporte sur sa face extérieure 27 un revêtement de flocage 28, lequel recouvre sur une certaine hauteur les surfaces latérales 25a et 25b de la grille 15 délimitant la gorge 25, comme on peut le voir sur la figure 2.The grid 15 has on its outer face 27 a flocking coating 28, which covers over a certain height the lateral surfaces 25a and 25b of the grid 15 delimiting the groove 25, as can be seen in FIG.

La face extérieure 27 est ici plane et s'étend obliquement par rapport à l'axe X de la tige 17, de sorte que l'embout 11 présente une forme générale biseautée.The outer face 27 is here planar and extends obliquely with respect to the X axis of the rod 17, so that the tip 11 has a generally beveled shape.

Dans l'exemple décrit, les ponts 15c se situent en retrait de la surface extérieure 27 et le revêtement de flocage 28 recouvre les surfaces latérales 25a et 25b sur une hauteur inférieure à la distance qui sépare la face extérieure 27 des ponts 15c.In the example described, the bridges 15c are set back from the outer surface 27 and the flocking coating 28 covers the side surfaces 25a and 25b to a height less than the distance between the outer face 27 of the bridges 15c.

Pour réaliser le revêtement de flocage 28, la grille 15 est revêtue d'adhésif sur sa face extérieure 27 par immersion partielle ou totale de celle-ci dans un bain adhésif, puis des poils sont déposés par voie électrostatique sur les régions de la grille 15 ainsi enduites d'adhésif.To achieve the flocking coating 28, the grid 15 is coated with adhesive on its outer face 27 by partial or total immersion thereof in an adhesive bath, and then hairs are deposited electrostatically on the regions of the grid 15 thus coated with adhesive.

L'adhésif utilisé est choisi pour présenter des viscosité et tension superficielle qui évitent la formation de films au niveau des ajours de la grille 15, afin de ne pas les obturer.The adhesive used is chosen to have viscosity and surface tension which prevent the formation of films at the openings of the grid 15, so as not to seal them.

Les poils peuvent avoir des diamètres, longueurs, natures divers ou sensiblement identiques, en fonction du produit destiné à être appliqué.The bristles may have diameters, lengths, various natures or substantially identical, depending on the product to be applied.

Les poils peuvent être notamment en polyamide, rayonne, polyester, viscose ou coton.The bristles may be in particular polyamide, rayon, polyester, viscose or cotton.

La longueur des poils peut être de 0,5 mm ou plus, par exemple.The length of the bristles may be 0.5 mm or more, for example.

Le revêtement de flocage recouvre sur une certaine hauteur la tranche extérieure de la grille 15, comme on peut le voir sur la figure 3.The flocking coating covers over a certain height the outer edge of the grid 15, as can be seen in FIG.

La grille 15 est alimentée en produit par le passage 30 précité, lequel fait communiquer le logement 24 avec l'intérieur du réservoir 12.The grid 15 is supplied with product by the aforementioned passage 30, which makes the housing 24 communicate with the interior of the reservoir 12.

Ce passage 30 débouche par un orifice 30a dans le fond du logement 24 à l'aplomb d'une région inférieure 25c de la gorge 25.This passage 30 opens through an orifice 30a in the bottom of the housing 24 in line with a lower region 25c of the groove 25.

Il en résulte que lorsque l'utilisateur tourne la molette 19, le produit commence par sortir par la région inférieure 25c de la gorge annulaire 25, comme illustré sur la figure 4, et ceci bien qu'il puisse exister un espace 33 entre la grille 15 et le fond du logement 24.As a result, when the user turns the wheel 19, the product begins to exit through the lower region 25c of the annular groove 25, as illustrated in FIG. 4, and this although there may be a space 33 between the gate 15 and the bottom of the dwelling 24.

Ainsi, l'utilisateur peut faire sortir en un emplacement non central de la face extérieure 27 une goutte G de produit P, comme illustré sur la figure 5.Thus, the user can output a non-central location of the outside face 27 a drop G of product P, as shown in FIG.

La goutte G se situe ici au niveau de la région inférieure de la face extérieure 27.Drop G is here at the lower region of outer face 27.

La gorge annulaire 25 n'étant que partiellement remplie de produit P lorsque ce dernier sort par sa région inférieure 25c, sa région supérieure 25d est capable d'absorber du produit lors de l'étalement de celui-ci sur la surface d'application, comme illustré sur la figure 6.The annular groove 25 being only partially filled with product P when the latter exits through its lower region 25c, its upper region 25d is capable of to absorb the product during spreading thereof on the application surface, as shown in Figure 6.

Le fait que le produit P sorte sur la face extérieure 27 de manière localisée permet à l'utilisateur de contrôler avec précision, avant l'application, la quantité de produit dont va se charger la face extérieure 27.The fact that the product P comes out on the outside face 27 in a localized manner enables the user to precisely control, before the application, the quantity of product which the external face 27 will be loaded with.

Par ailleurs, le risque que le produit se trouve en excès sur la surface d'application est réduit grâce à la capacité d'absorption de produit des régions de la gorge annulaire 25 éloignées de celle par laquelle sort le produit.On the other hand, the risk of the product being in excess on the application surface is reduced by the product absorption capacity of the regions of the annular groove 25 away from that through which the product leaves.

L'espace 33 peut être choisi suffisamment large pour permettre une certaine recirculation du produit sous la grille.The space 33 may be chosen large enough to allow some recirculation of the product under the grid.

En effet, la circulation du produit depuis le passage 30 vers la région 25c de la gorge 25 tend à créer, si la vitesse du produit est suffisante, un effet d'entraînement et d'aspiration du produit contenu dans l'espace 33, lequel se mélange ainsi au produit gagnant la région 25c et provoque le vidage au moins partiel de la région 25d.Indeed, the circulation of the product from the passage 30 to the region 25c of the groove 25 tends to create, if the speed of the product is sufficient, a drive and suction effect of the product contained in the space 33, which thus mixing with the product gaining the region 25c and causing at least partial emptying of the region 25d.

Cette dernière peut donc à nouveau accepter une certaine quantité de produit présent en excès sur la surface d'application.The latter can therefore again accept a certain amount of product present in excess on the application surface.

De plus, la recirculation du produit tend à éviter que du produit ne reste trop longtemps dans l'embout sans être utilisé et ne se dégrade.In addition, recirculation of the product tends to prevent the product from staying too long in the mouthpiece without being used and does not degrade.

De préférence, comme dans l'exemple décrit, la largeur de la gorge 25 est choisie de telle sorte que la surface de la peau ou des muqueuses au contact de l'embout 11 au moment de l'application du produit puisse se déformer légèrement et plonger dans le produit contenu dans la gorge, comme illustré sur la figure 7.Preferably, as in the example described, the width of the groove 25 is chosen so that the surface of the skin or mucous membranes in contact with the tip 11 at the time of application of the product may deform slightly and dive into the product contained in the groove, as shown in Figure 7.

On remarquera que dans l'exemple décrit, le revêtement de flocage 28 s'étend au moins jusqu'au bord périphérique 28a de la grille 15, défini par une arête, ce bord 28a étant au contact de l'extrémité supérieure non floquée de la jupe 23, ce qui permet d'obtenir un flocage ayant un contour net vu de l'extérieur.It will be noted that in the example described, the flocking coating 28 extends at least up to the peripheral edge 28a of the grid 15, defined by an edge, this edge 28a being in contact with the unpulterated upper end of the skirt 23, which allows to obtain a flocking having a sharp outline from the outside.

On remarquera également que le risque de bouchage par le revêtement de flocage du passage qui alimente la surface d'application est réduit, compte tenu des dimensions relativement importantes de la gorge annulaire 25 et du fait que l'orifice 30a n'est pas exposé à l'adhésif utilisé pour floquer la grille 15.It will also be noted that the risk of clogging by the flocking coating of the passage which feeds the application surface is reduced, given the relatively large dimensions of the annular groove 25 and the fact that the orifice 30a is not exposed to the adhesive used to flock the grid 15.

Bien entendu, on peut réaliser l'embout avec d'autres configurations sans sortir du cadre de la présente invention.Of course, one can achieve the tip with other configurations without departing from the scope of the present invention.

A titre d'exemple, on a représenté sur les figures 8 à 10 un embout 40 comportant une partie de support ou base 41 et un élément rapporté ou grille 42.By way of example, FIGS. 8 to 10 show a tip 40 comprising a support or base portion 41 and an insert element or grid 42.

La partie de support 41 comporte une partie inférieure 43 traversée par un passage central 44 communiquant avec le réservoir contenant le produit et une partie supérieure 45 définissant un logement 46 dans lequel est fixée la partie rapportée 42.The support portion 41 has a lower portion 43 traversed by a central passage 44 communicating with the reservoir containing the product and an upper portion 45 defining a housing 46 in which the attached portion 42 is fixed.

Cette partie supérieure 45 se présente sous la forme d'une jupe tubulaire de hauteur variable, l'extrémité supérieure de cette jupe tubulaire étant sensiblement tangente à un plan incliné par rapport à l'axe de l'embout.This upper portion 45 is in the form of a tubular skirt of variable height, the upper end of this tubular skirt being substantially tangent to a plane inclined relative to the axis of the tip.

La partie rapportée 42 présente une face extérieure 47 destinée à définir une surface d'application et recouverte par un revêtement de flocage 48.The insert 42 has an outer face 47 for defining an application surface and covered by a flocking coating 48.

L'embout 40 présente une forme générale biseautée.The tip 40 has a generally beveled shape.

La partie rapportée 42 comporte une partie centrale 42a et une partie périphérique 42b, reliées par des ponts de matière 42c, à l'instar de la grille 15 précédemment décrite.The attached portion 42 has a central portion 42a and a peripheral portion 42b, connected by material bridges 42c, like the grid 15 described above.

La partie rapportée 42 est fixée par encliquetage dans le logement 46, comme dans l'exemple de réalisation précédent.The attached portion 42 is snapped into the housing 46, as in the previous embodiment.

La partie centrale 42a ménage avec la partie périphérique 42b une gorge annulaire 49.The central portion 42a includes the peripheral portion 42b with an annular groove 49.

Le revêtement de flocage 48 s'étend quelque peu dans la gorge annulaire 49, en venant recouvrir les arêtes des parties 42a et 42b bordant cette gorge.The flocking coating 48 extends somewhat in the annular groove 49, coming to cover the edges of the portions 42a and 42b bordering this groove.

Lors de la distribution du produit, ce dernier sort de manière privilégiée par la région inférieure 49a de la gorge 49 en raison de la moindre hauteur de celle-ci, comme on peut le voir sur la figure 9.During the distribution of the product, the latter exits in a preferred manner by the lower region 49a of the groove 49 because of the lower height thereof, as can be seen in FIG. 9.

La région supérieure 49b de la gorge 49 permet de récupérer du produit se trouvant en excès sur la surface d'application 47, comme illustré sur la figure 10.The upper region 49b of the groove 49 makes it possible to recover excess product on the application surface 47, as illustrated in FIG. 10.

La partie centrale 42a agit à la manière d'un brise-jet de par son positionnement en face du passage 44.The central portion 42a acts in the manner of a jetbreaker by its positioning in front of the passage 44.

Le revêtement de flocage 48 s'étend jusqu'au bord périphérique 48a de la partie rapportée 42 défini par une arête, au contact de l'extrémité supérieure non floquée 45a de la jupe tubulaire 45.The flocking coating 48 extends to the peripheral edge 48a of the insert portion 42 defined by a ridge, in contact with the non-flocked upper end 45a of the tubular skirt 45.

On a représenté sur la figure 11, dans une vue analogue à celles des figures 8 à 10, un embout 50 comportant une partie de support 51 identique à la partie de support 41 précédemment décrite, et une partie rapportée 52.FIG. 11 shows, in a view similar to that of FIGS. 8 to 10, an end piece 50 comprising a support part 51 identical to the support part. 41 previously described, and a reported part 52.

Cette dernière comporte une partie centrale 52a et une partie périphérique 52b reliées entre elles par des ponts de matière 52c.The latter comprises a central portion 52a and a peripheral portion 52b interconnected by material bridges 52c.

La face extérieure 57 de la partie rapportée 52 définit une surface d'application.The outer face 57 of the insert 52 defines an application surface.

La partie périphérique 52b est identique à la partie périphérique 42b précédemment décrite et elle est fixée de la même manière sur la partie de support 51.The peripheral portion 52b is identical to the peripheral portion 42b previously described and is fixed in the same manner on the support portion 51.

La partie centrale 52a présente en partie inférieure une portion formant obturateur 54 qui vient s'appliquer au repos contre le fond du logement 46, afin d'obturer le passage 44 faisant communiquer le logement 46 avec la réserve de produit.The central portion 52a has in the lower part a shutter portion 54 which is applied at rest against the bottom of the housing 46, to seal the passage 44 communicating the housing 46 with the product supply.

Cette dernière est ainsi isolée de l'air ambiant sauf lors de l'alimentation de l'embout en produit.The latter is thus isolated from the ambient air except when feeding the tip product.

Les ponts 52c sont réalisés de manière à permettre une certaine mobilité de la partie centrale 52a, sous l'effet de la pression du produit dans le passage 44.The bridges 52c are made to allow a certain mobility of the central portion 52a, under the effect of the pressure of the product in the passage 44.

La partie formant obturateur 54 est conformée en pointeau de manière à permettre, lorsqu'elle s'écarte du fond de logement 46, un passage de produit en direction de la surface d'application.The shutter portion 54 is shaped as a needle so as to allow, when it deviates from the housing bottom 46, a product passage towards the application surface.

On a représenté sur les figures 12 à 17 différentes configurations d'embouts pour bien montrer que l'invention n'est pas limitée aux deux configurations qui viennent d'être décrites.FIGS. 12 to 17 show various configurations of end pieces to show clearly that the invention is not limited to the two configurations which have just been described.

On a ainsi représenté sur la figure 12 un embout 60 qui comporte une partie de support ou base 61 qui est ici identique à la partie de support 14 précédemment décrite et une grille ou partie rapportée 62 comportant une partie centrale 62a et une partie périphérique 62b réunies par des ponts 62c.FIG. 12 shows thus a tip 60 which includes a support portion or base 61 which is here identical to the support portion 14 previously described and a grid or insert 62 comprising a central portion 62a and a peripheral portion 62b joined together by bridges 62c.

La grille 62 comporte des barreaux inférieur et supérieur 62d parallèles aux ponts 62c.The gate 62 has lower and upper rungs 62d parallel to the bridges 62c.

La grille 62 définit plusieurs cavités 63a, 63b, 63c et 63d dont le fond se situe en retrait de la surface d'application.The gate 62 defines a plurality of cavities 63a, 63b, 63c and 63d, the bottom of which is set back from the application surface.

La cavité 63a est formée entre la partie périphérique 62b et le barreau 62d inférieur.The cavity 63a is formed between the peripheral portion 62b and the lower bar 62d.

La cavité 63b est formée entre la partie périphérique 62b, le barreau 62d inférieur et la partie centrale 62a.The cavity 63b is formed between the peripheral portion 62b, the lower bar 62d and the central portion 62a.

La cavité 63c est formée entre la partie centrale 62a, le barreau 62d supérieur et la partie périphérique 62b.The cavity 63c is formed between the central portion 62a, the upper bar 62d and the peripheral portion 62b.

La cavité 63d est formée entre le barreau 62d supérieur et la partie périphérique 62b.The cavity 63d is formed between the upper bar 62d and the peripheral portion 62b.

Un orifice 64 débouche dans le fond du logement recevant la grille 62 pour alimenter la surface d'application en produit.An orifice 64 opens into the bottom of the housing receiving the gate 62 to supply the product application surface.

Dans l'exemple décrit, cet orifice 64 débouche dans la région 63 a précitée.In the example described, this orifice 64 opens into the region 63 a above.

Toutes les cavités 63a à 63d communiquent entre elles sous la grille 62.All the cavities 63a to 63d communicate with each other under the gate 62.

Du produit présent en excès sur la surface d'application peut être récupéré par l'une des régions 63b à 63d, d'une manière similaire à ce qui se produit dans les exemples de réalisation précédemment décrits.Excess product present on the application surface may be recovered by one of regions 63b-63d, in a manner similar to what occurs in the previously described embodiments.

La grille 62 est recouverte en totalité sur sa face extérieure par un revêtement de flocage, lequel s'étend jusqu'à la jupe annulaire de la base 61, non floquée, qui entoure la grille 62.The gate 62 is entirely covered on its outer face by a flocking coating, which extends to the annular skirt of the base 61, not flocked, which surrounds the gate 62.

On a représenté sur la figure 13 un embout 70 qui diffère principalement de celui représenté à la figure 5 par le fait que la partie centrale 15a est remplacée par une partie centrale 75a de plus grand diamètre, qui occupe la majeure partie de la surface d'application.FIG. 13 shows a tip 70 which differs mainly from that shown in FIG. 5 in that the central portion 15 a is replaced by a central portion 75 a of larger diameter, which occupies most of the surface of application.

Le contour de la grille, à sa jonction avec la partie de support, peut être autre que circulaire.The outline of the grid, at its junction with the support portion, may be other than circular.

A titre d'exemple, on a représenté sur la figure 14 un embout 80 comportant une grille 81 fixée sur une partie de support 82.By way of example, FIG. 14 shows a tip 80 comprising a grid 81 fixed on a support portion 82.

La partie de support 82 présente une face frontale 83 en biseau et un logement débouchant sur cette face frontale pour accueillir la grille 81.The support portion 82 has a front face 83 beveled and a housing opening on this front face to accommodate the grid 81.

On voit sur la figure 14 que la grille 81 comporte une partie centrale 81a et une partie périphérique 81b reliées entre elles par des ponts de matière 81c, la partie périphérique 81b présentant un revêtement de flocage jusqu'à un bord 84, lequel présente des ondulations et se situe au contact d'un bord correspondant 85 de forme complémentaire non floqué de la face frontale 83.FIG. 14 shows that the grid 81 comprises a central portion 81a and a peripheral portion 81b interconnected by material bridges 81c, the peripheral portion 81b having a flocking coating to an edge 84, which has corrugations and is in contact with a corresponding edge 85 of complementary non-flocked shape of the end face 83.

On a représenté sur la figure 15 un embout 90 comportant une partie de support recevant une grille 91 ayant une partie centrale 91a et une partie périphérique 91b.FIG. 15 shows a nozzle 90 comprising a support portion receiving a grid 91 having a central portion 91a and a peripheral portion 91b.

La partie périphérique 91b comporte un revêtement de flocage jusqu'à son bord radialement extérieur 92, lequel est au contact d'un bord non floqué 93 de la partie de support 94.The peripheral portion 91b has a flocking coating to its radially outer edge 92, which is in contact with an unpouched edge 93 of the support portion 94.

La partie périphérique 91b comporte un bord ondulé 95 entourant la partie centrale 91a.The peripheral portion 91b has a corrugated edge 95 surrounding the central portion 91a.

On a représenté sur la figure 16 un embout 100 comportant une partie de support 101 et une partie rapportée 102, cette dernière comprenant une partie centrale 102a et une partie périphérique 102b reliées entre elles par des ponts de matière 102c.FIG. 16 shows a tip 100 having a support portion 101 and an attached portion 102, the latter including a central portion 102a and a peripheral portion 102b interconnected by material bridges 102c.

La partie de support 101 comporte une jupe tubulaire 103 dont le bord supérieur 104 présente des ondulations.The support portion 101 has a tubular skirt 103 whose upper edge 104 has corrugations.

La pièce rapportée 102 comporte également une jupe tubulaire 105, dont le bord inférieur 106 présente une forme complémentaire de celle du bord 104, de sorte que les deux bords 104 et 106 viennent en totalité au contact l'un de l'autre, comme représenté sur la figure 16.The insert 102 also comprises a tubular skirt 105, whose lower edge 106 has a shape complementary to that of the edge 104, so that the two edges 104 and 106 come in full contact with one another, as shown in Figure 16.

La pièce rapportée 102 présente un revêtement de flocage à la fois sur sa face frontale 108 et sur sa surface latérale 109.The insert 102 has a flock coating on both its end face 108 and its side surface 109.

Ce revêtement de flocage s'étend jusqu'au bord 106 et vient au contact du bord non floqué 104 de la partie du support. Le bord 106 est un bord libre de la pièce rapportée.This flocking coating extends to the edge 106 and comes into contact with the non-flocked edge 104 of the support portion. Edge 106 is a free edge of the insert.

On remarquera que l'on peut obtenir, grâce à l'appui de la jupe 105, qui est floquée, sur le bord 104 de la partie de support, un revêtement de flocage présentant un contour net, sans qu'il soit nécessaire de recouvrir la jupe 105 par un cache.It will be noted that it is possible to obtain, thanks to the support of the skirt 105, which is flocked, on the edge 104 of the support part, a flocking coating having a clean contour, without it being necessary to cover the skirt 105 by a cover.

On peut donner à l'embout d'autres formes encore et la surface latérale de l'embout peut être non symétrique de révolution.Other shapes may be given to the mouthpiece and the lateral surface of the mouthpiece may be non-symmetrical of revolution.

A titre d'exemple, on a représenté sur la figure 17 un embout 110 qui comporte une partie de support 111 et une partie rapportée 112, cette dernière comprenant une partie inférieure 112a qui vient au contact de la partie de support 111 et une partie déportée 112b, excentrée par rapport à l'axe de la partie de support 111.By way of example, there is shown in FIG. 17 a tip 110 which includes a support portion 111 and an attached portion 112, the latter including a lower portion 112a which comes into contact with the support portion 111 and a remote portion 112b, eccentric to the axis of the support portion 111.

La partie rapportée 112 présente une face supérieure 113 formant un biseau. L'ensemble de la surface extérieure de la partie rapportée 112 présente un revêtement de flocage.The attached portion 112 has an upper face 113 forming a bevel. The entire outer surface of the insert 112 has a flock coating.

Ce revêtement de flocage s'étend jusqu'au bord supérieur non floqué de la partie de support 111.This flocking coating extends to the unflocked upper edge of the support part 111.

On peut prévoir divers moyens pour conditionner le produit et alimenter la surface d'application en produit.Various means can be provided for conditioning the product and supplying the application surface with product.

Ainsi, le réservoir à piston et vis d'entraînement de la figure 1 peut être remplacé par le réservoir à paroi déformable illustré à la figure 18.Thus, the piston reservoir and drive screw of Figure 1 can be replaced by the deformable wall reservoir illustrated in Figure 18.

Sur cette figure, on a représenté un dispositif de conditionnement et d'application 120 qui comporte un embout 121 identique à l'embout 11 précédemment décrit et un réservoir constitué par un tube 122.In this figure, there is shown a packaging and application device 120 which comprises a nozzle 121 identical to the nozzle 11 described above and a tank constituted by a tube 122.

La base de l'embout 121 est ici réalisée d'un seul tenant avec le tube mais pourrait, en variante, être constituée par un élément rapporté sur le tube.The base of the nozzle 121 is here made in one piece with the tube but could, alternatively, be constituted by an element attached to the tube.

On peut encore utiliser comme illustré sur la figure 19 une pompe pour alimenter la surface d'application en produit.It is still possible to use, as illustrated in FIG. 19, a pump for supplying the application surface with product.

Sur cette figure, on a représenté un dispositif 130 qui comporte un corps 134 surmonté par un embout 131 portant une grille 132 similaire à la grille 42 décrite en référence aux figures 8 à 10, comprenant une gorge annulaire 153 et une partie de support 133 fixée sur le corps 134.In this figure, there is shown a device 130 which comprises a body 134 surmounted by a tip 131 carrying a grid 132 similar to the gate 42 described with reference to Figures 8 to 10, comprising an annular groove 153 and a support portion 133 fixed on the body 134.

Le corps 134 est ouvert à son extrémité inférieure 135 pour recevoir une recharge 136 comprenant un réservoir 137 contenant du produit et une pompe 138 comportant une tige creuse de commande 139.The body 134 is open at its lower end 135 to receive a refill 136 comprising a reservoir 137 containing product and a pump 138 having a hollow control rod 139.

La tige 139 est insérée à force dans un logement 140 situé en partie supérieure du corps 134.The rod 139 is inserted by force into a housing 140 located in the upper part of the body 134.

Ce logement 140 comporte un passage 141 débouchant dans le fond du logement 142 de la partie de support 133 dans lequel est fixée la grille 132.This housing 140 has a passage 141 opening into the bottom of the housing 142 of the support portion 133 in which the grid 132 is fixed.

Lorsque la pompe 138 est au repos, la recharge 136 déborde vers le bas du corps 134.When the pump 138 is at rest, the refill 136 overflows down the body 134.

L'utilisateur peut, en appuyant sur le fond 144 du réservoir 137, pousser la recharge 136 en direction de la partie supérieure 145 du corps 134 et provoquer l'actionnement de la tige 139 et la distribution d'une dose de produit.The user can, by pressing the bottom 144 of the reservoir 137, push the refill 136 towards the upper portion 145 of the body 134 and cause the actuation of the rod 139 and the dispensing of a dose of product.

Le produit sortant par l'extrémité supérieure de la tige 139 alimente la surface d'application de manière similaire à ce qui a été décrit en référence aux figures 8 à 10.The product exiting through the upper end of the rod 139 feeds the application surface in a manner similar to that described with reference to FIGS. 8 to 10.

Avantageusement, comme illustré sur la figure 20, le dispositif 130 comporte un capuchon de fermeture 151 qui est apte à se fixer de manière étanche sur le corps 134 par encliquetage par exemple et qui comprend une jupe intérieure 148 dont le bord inférieur 150 est apte à s'engager dans la gorge annulaire 153, de manière à empêcher la sortie du produit et à protéger de l'air ambiant le produit éventuellement présent sous la grille 132 et dans la gorge 153.Advantageously, as illustrated in FIG. 20, the device 130 comprises a closing cap 151 which is able to be fixed in a sealed manner on the body 134 by snap-fastening for example and which comprises an inner skirt 148 whose lower edge 150 is able to engage in the annular groove 153, so as to prevent the product from leaving and to protect the ambient air possibly present under the gate 132 and in the throat 153.

On peut encore réaliser l'embout avec une grille présentant une face extérieure convexe vers l'extérieur, comme illustré sur la figure 21 ou concave vers l'extérieur, comme illustré sur la figure 22.It is also possible to make the endpiece with a grid having an outwardly convex outer face, as shown in FIG. 21 or concave outwards, as illustrated in FIG. 22.

On peut encore réaliser l'embout avec une grille floquée en totalité, comme illustré sur la figure 23.We can still achieve the tip with a grid flocked in full, as shown in Figure 23.

On voit sur cette figure que le revêtement de flocage s'étend sur la face extérieure de l'embout, jusqu'au bord 155 de la grille, et que ce bord est sensiblement au contact du bord 156 non floqué correspondant de la partie de support recevant la grille.It is seen in this figure that the flocking coating extends on the outer face of the nozzle, to the edge 155 of the grid, and that this edge is substantially in contact with the corresponding unbroken edge 156 of the support portion. receiving the grid.

Bien qu'il soit préférable que la surface servant à l'application du produit soit en biseau pour faciliter l'application du produit et la réalisation d'un maquillage soigné, on ne sort pas du cadre de la présente invention lorsque la surface d'application s'étend perpendiculairement à l'axe de la partie de support, comme illustré sur la figure 23.Although it is preferable that the surface used for the application of the product be beveled to facilitate the application of the product and the achievement of a neat makeup, it is not beyond the scope of the present invention when the surface of application extends perpendicularly to the axis of the support portion, as shown in Figure 23.

De plus, bien qu'il soit également préférable que le produit arrive de manière privilégiée sur la surface d'application en une région limitée d'une gorge ou d'une cavité, comme cela est le cas des dispositifs qui viennent d'être précédemment décrits, on ne sort pas du cadre de la présente invention lorsque le produit arrive sur la surface d'application de manière uniforme.In addition, although it is also preferable that the product arrives in a privileged manner on the application surface in a limited region of a groove or a cavity, as is the case of the devices that have just been described, it is not beyond the scope of the present invention when the product arrives on the application surface uniformly.

On a représenté sur la figure 24 un embout 160 comportant une grille 163 ayant une région centrale 163a.FIG. 24 shows a tip 160 comprising a gate 163 having a central region 163a.

La surface d'application 161 s'étend perpendiculairement à l'axe de l'embout et le produit gagne de manière uniforme la surface d'application 161, de par le fait que celle-ci est alimentée par un passage 162 débouchant au centre du logement recevant la grille 163, cette dernière ne comportant que des passages 164 identiques réalisés autour de la région centrale 163a.The application surface 161 extends perpendicular to the axis of the tip and the product evenly gains the application surface 161, in that it is fed by a passage 162 opening at the center of the housing receiving the grid 163, the latter having only identical passages 164 made around the central region 163a.

On peut réaliser la partie de support et la grille de multiples manières encore sans sortir du cadre de la présente invention.The support portion and the grid can be made in many ways without departing from the scope of the present invention.

On peut notamment réaliser un brise-jet d'un seul tenant avec la partie de support.In particular, it is possible to produce a single-piece jetbreaker with the support part.

A titre d'exemple, on a représenté sur la figure 25 un embout 170 comportant une partie support 171 et une grille 172 rapportée sur celle-ci.For example, there is shown in Figure 25 a nozzle 170 having a support portion 171 and a grid 172 attached thereto.

La partie de support 171 comporte un passage 173 permettant d'alimenter la grille 172 en produit.The support portion 171 has a passage 173 for feeding the gate 172 product.

Un brise-jet 174 est réalisé d'un seul tenant avec la partie support 171.A jetbreaker 174 is made in one piece with the support portion 171.

On remarquera que dans cet exemple la grille 172 est prolongée vers le bas à sa périphérie par une jupe de fixation 175 qui vient s'encliqueter de manière étanche sur un godron 176 formé sur la pièce de support 171.It will be noted that in this example the grid 172 is extended downwards at its periphery by a fixing skirt 175 which snaps tightly onto a godron 176 formed on the support piece 171.
