The receptacle includes a wiper (11) wiping the applicator element while it is removed from the receptacle. The applicator element includes an end face substantially plane and substantially parallel to the longitudinal axis of the distal portion of the stem, where the end face is situated on a side of the applicator element that is opposite to the longitudinal axis of the distal portion of the stem. An independent claim is also included for a method for applying a composition to skin or lips.

Description

La présente invention concerne les dispositifs de conditionnement et d'application pour appliquer un produit sur la peau ou les lèvres.The present invention relates to packaging and application devices for applying a product to the skin or the lips.

L'invention concerne plus particulièrement les dispositifs dans lesquels l'applicateur comporte un élément d'application porté par une tige et introduit dans un récipient pour être chargé en produit.The invention relates more particularly to devices in which the applicator comprises an applicator element carried by a rod and introduced into a container to be loaded with product.

Le brevet US 6 220 254 et la demande de brevet EP 0 916 282 divulguent des dispositifs dans lesquels l'applicateur comporte un élément d'application qui présente une extrémité libre éloignée de l'axe longitudinal de la portion distale de la tige. Le récipient contenant le produit à appliquer est pourvu d'un organe essorage comportant un bloc de mousse. L'utilisation d'un bloc de mousse peut faciliter l'obtention d'un essorage homogène de l'élément d'application. Toutefois, la présence du bloc de mousse peut imposer des contraintes sur la réalisation du récipient, liées notamment à la fixation du bloc de mousse dans le récipient.The patent US 6,220,254 and the patent application EP 0 916 282 disclose devices in which the applicator has an applicator element which has a free end remote from the longitudinal axis of the distal portion of the shaft. The container containing the product to be applied is provided with a wringing member comprising a block of foam. The use of a foam block can facilitate obtaining a uniform spin of the application element. However, the presence of the foam block may impose constraints on the realization of the container, particularly related to the attachment of the foam block in the container.

La demande de brevet européen EP 1 053 695 divulgue des dispositifs de conditionnement et d'application dans lesquels l'élément d'application présente également une extrémité distale qui est éloignée de l'axe longitudinal de la portion distale de la tige. Ces dispositifs permettent de réaliser un essorage inhomogène de l'élément d'application, permettant d'accumuler du produit sur un côté de l'élément d'application.The European patent application EP 1 053 695 discloses conditioning and application devices in which the application element also has a distal end which is remote from the longitudinal axis of the distal portion of the shaft. These devices make it possible to perform an inhomogeneous spinning of the applicator element, making it possible to accumulate product on one side of the applicator element.

Le brevet US 6 070 598 décrit des applicateurs dont l'élément d'application présente une extrémité libre biseautée. Il peut se former, lorsque de tels applicateurs sont extraits d'un récipient comportant un organe d'essorage conventionnel, une goutte de produit à l'extrémité de l'élément d'application, sur le biseau de celui-ci. Une telle goutte de produit peut nuire à l'homogénéité du dépôt de produit sur la surface à traiter, ce qui pour un brillant à lèvres n'est pas très gênant, mais peut le devenir pour un produit destiné à apporter de la couleur.The patent US 6,070,598 describes applicators whose application element has a beveled free end. When such applicators are extracted from a container having a conventional wiper member, a drop of product may be formed at the end of the applicator element on the bevel thereof. Such a drop of product may adversely affect the homogeneity of the product deposit on the surface to be treated, which for a lip gloss is not very troublesome, but may become so for a product intended to provide color.

La demande EP 1 336 353 divulgue un élément d'application pour appliquer un produit tel qu'un eyeliner sur les paupières, ayant à une extrémité des pointes permettant de tracer des traits, ces pointes pouvant être décalées latéralement relativement à l'axe longitudinal de la portion distale de la tige afin d'améliorer par exemple la perception du tracé effectué avec les pointes.Requirement EP 1 336 353 discloses an application member for applying a product such as an eyeliner to the eyelids, having at one end points for tracing lines, these tips being laterally offset relative to the longitudinal axis of the distal portion of the shank in order to improve, for example, the perception of the trace made with the tips.

Le brevet US 5 881743 divulgue un applicateur moulé présentant une zone amincie délimitant une partie de préhension et une partie applicatrice définissant une surface d'application inclinée.The patent US 5 881743 discloses a molded applicator having a tapered zone defining a gripping portion and an applicator portion defining an inclined application surface.

On connaît par les demandes de brevet EP 1 745 717 et US 2007/0017544 des applicateurs dont l'élément d'application présente au moins une zone amincie formant charnière, entre des portions proximale et distale. Ces applicateurs permettent un essorage inhomogène de l'élément d'application, avec accumulation de produit sur la face d'extrémité.Patent applications are known EP 1 745 717 and US 2007/0017544 applicators whose applicator element has at least one hinged thinned area between proximal and distal portions. These applicators allow an inhomogeneous spinning of the application element, with accumulation of product on the end face.

Il existe un besoin pour perfectionner encore les dispositifs de conditionnement et d'application servant à appliquer un produit sur la peau ou les lèvres.There is a need to further improve the conditioning and application devices for applying a product to the skin or the lips.

Selon l'un de ses aspects, l'invention a pour objet un dispositif de conditionnement et d'application pour appliquer un produit sur la peau ou les lèvres, comportant :

  • un applicateur comportant une tige ayant une partie distale et un élément d'application porté par la partie distale de la tige,
  • un récipient contenant le produit à appliquer sur la peau ou les lèvres, le récipient étant muni d'au moins un organe d'essorage pour essorer l'élément d'application lors de son retrait du récipient,
l'élément d'application ayant un axe longitudinal non confondu avec l'axe longitudinal de la partie distale de la tige, par exemple faisant un angle non nul avec celui-ci,
l'élément d'application ayant une face d'extrémité de surface enveloppe sensiblement plane et sensiblement parallèle à l'axe longitudinal de la partie distale de la tige, cette face d'extrémité étant située du côté de l'élément d'application opposé à l'axe longitudinal de la partie distale de la tige.According to one of its aspects, the subject of the invention is a device for packaging and applying to apply a product to the skin or the lips, comprising:
  • an applicator having a shaft having a distal portion and an applicator member carried by the distal portion of the shaft,
  • a container containing the product to be applied to the skin or the lips, the container being provided with at least one dewatering member for dewatering the applicator element when it is withdrawn from the container,
the applicator element having a longitudinal axis not coincident with the longitudinal axis of the distal portion of the stem, for example forming a non-zero angle therewith,
the applicator element having a substantially planar envelope surface end face substantially parallel to the longitudinal axis of the distal portion of the shaft, said end face being located on the opposite side of the applicator element to the longitudinal axis of the distal part of the stem.

L'invention convient tout particulièrement à l'application d'un produit sur les lèvres mais peut servir également à l'application sur les paupières.The invention is particularly suitable for applying a product to the lips but can also be used for application on the eyelids.

Par « sensiblement plane », il faut comprendre que la surface enveloppe peut être plane ou légèrement concave ou convexe. La plus grande flèche de la surface enveloppe, mesurée par rapport à son bord, est par exemple inférieure ou égale à 1,2 mm, mieux à 0,5 mm.By "substantially flat", it should be understood that the envelope surface may be flat or slightly concave or convex. The largest arrow of the envelope surface, measured with respect to its edge, is for example less than or equal to 1.2 mm, better to 0.5 mm.

Par « sensiblement parallèle », il faut comprendre un angle inférieur ou égal à ± 10° avec l'axe longitudinal de la partie distale de la tige, mieux à ± 5°.By "substantially parallel" is meant an angle less than or equal to ± 10 ° to the longitudinal axis of the distal portion of the stem, more preferably ± 5 °.

L'axe longitudinal de l'élément d'application peut être défini, lorsqu'il n'est pas rectiligne, comme l'axe qui suit le barycentre de la surface enveloppe de l'élément d'application. Dans le cas d'une section transversale d'enveloppe circulaire, polygonale ou présentant une symétrie axiale, l'axe passe par le centre de la section. L'élément d'application peut avoir un axe longitudinal qui fait un angle avec l'axe longitudinal de la partie distale de la tige au moins dans la région de l'élément d'application qui vient extérieurement immédiatement dans le prolongement de la tige.The longitudinal axis of the applicator element may be defined, when not rectilinear, as the axis which follows the centroid of the envelope surface of the applicator element. In the case of a circular, polygonal or axially symmetrical envelope cross-section, the axis passes through the center of the section. The applicator element may have a longitudinal axis which is at an angle to the longitudinal axis of the distal portion of the shaft at least in the region of the applicator element which comes externally immediately in the extension of the shaft.

Un dispositif selon l'invention peut permettre d'essorer l'élément d'application sans former de goutte de produit en excès sur la face d'extrémité, laquelle peut, grâce à son orientation, être essuyée convenablement par l'organe d'essorage, contrairement à un élément d'application ayant son axe longitudinal confondu avec celui de la tige.A device according to the invention can make it possible to wring the applicator element without forming excess product droplet on the end face, which, thanks to its orientation, can be wiped off appropriately by the wringing member. , unlike an application element having its longitudinal axis coincident with that of the rod.

L'invention peut convenir à l'application d'un produit relativement fluide.The invention may be suitable for applying a relatively fluid product.

L'invention peut ainsi permettre l'application d'une couche de produit d'épaisseur relativement homogène, ce qui est avantageux notamment lorsque le produit est coloré et que l'on recherche une uniformité de la couleur à l'application.The invention can thus allow the application of a layer of product of relatively homogeneous thickness, which is advantageous especially when the product is colored and that it seeks uniformity of color application.

De plus, l'invention peut permettre de bénéficier, si cela est recherché, d'une face d'extrémité relativement étendue, ce qui peut faciliter le maquillage, en permettant une application à la fois rapide et précise. L'application peut s'effectuer grâce à la face d'extrémité mais également le cas échéant grâce à une autre surface de l'élément d'application, par exemple une surface située sensiblement à l'opposé de la face d'extrémité.In addition, the invention can make it possible to benefit, if desired, from a relatively large end face, which can facilitate the makeup, by allowing an application that is both fast and accurate. The application can be made through the end face but also if necessary through another surface of the application element, for example a surface located substantially opposite the end face.

La face d'extrémité peut être relativement étendue dans le sens axial et s'étendre par exemple le long de l'axe longitudinal de la partie distale de la tige sur une distance supérieure ou égale à 2, 3 ou 4 mm, par exemple une distance allant de 2 mm à 15 mm.The end face may be relatively extended in the axial direction and extend for example along the longitudinal axis of the distal portion of the rod over a distance greater than or equal to 2, 3 or 4 mm, for example a distance from 2 mm to 15 mm.

La face d'extrémité peut s'étendre ou non jusqu'à l'extrémité distale de l'élément d'application. La face d'extrémité peut être éloignée, en au moins un point, de l'extrémité distale de l'élément d'application d'une distance inférieure ou égale à 1 mm. L'élément d'application peut se déformer élastiquement pour franchir l'organe d'essorage.The end face may or may not extend to the distal end of the applicator element. The end face may be at least one point away from the distal end of the applicator member by a distance of less than or equal to 1 mm. The application element can deform elastically to cross the wiper member.

La face d'extrémité peut être relativement éloignée de l'axe longitudinal de la partie distale de la tige, par exemple d'une distance supérieure ou égale à 2, 3 ou 4 mm. Dans le cas où la tige est solidaire d'un capuchon de fermeture du récipient, la face d'extrémité peut être suffisamment proche de l'axe longitudinal de la tige pour que l'applicateur puisse rouler sur une surface plane horizontale sans que l'élément d'application ne touche cette surface.The end face may be relatively remote from the longitudinal axis of the distal portion of the rod, for example by a distance greater than or equal to 2, 3 or 4 mm. In the case where the rod is secured to a closure cap of the container, the face end can be sufficiently close to the longitudinal axis of the rod so that the applicator can roll on a horizontal flat surface without the applicator element touching this surface.

L'élément d'application peut comporter un bec aplati et la face d'extrémité peut être définie au moins partiellement par ce bec aplati.The applicator element may comprise a flattened nose and the end face may be defined at least partially by this flattened nose.

L'élément d'application peut s'étendre selon un axe longitudinal qui fait un angle avec celui de la partie distale de la tige, cet angle étant par exemple compris entre 5 et 45°, mieux 10 et 35°. Une telle valeur d'angle participe à l'ergonomie de l'applicateur.The applicator element may extend along a longitudinal axis that is at an angle with that of the distal portion of the rod, this angle being for example between 5 and 45 °, better 10 and 35 °. Such an angle value contributes to the ergonomics of the applicator.

L'élément d'application peut s'étendre avec un axe longitudinal rectiligne ou non, l'axe longitudinal de l'élément d'application étant par exemple curviligne, notamment concave ou convexe du côté de l'axe longitudinal de la partie distale de la tige, ou comportant plusieurs segments ayant des orientations différentes, notamment lorsque l'élément d'application présente un bec aplati définissant au moins partiellement la face d'extrémité.The applicator element may extend with a rectilinear longitudinal axis or not, the longitudinal axis of the applicator element being for example curvilinear, in particular concave or convex on the side of the longitudinal axis of the distal portion of the applicator element. the rod, or having several segments having different orientations, especially when the applicator element has a flattened nose defining at least partially the end face.

La face d'extrémité peut présenter une largeur qui diminue en direction de l'extrémité distale, ce qui peut permettre par exemple de former une pointe à l'extrémité de l'élément d'application et d'obtenir plus de précision à l'application. La face d'extrémité est par exemple de forme sensiblement triangulaire ou elliptique.The end face may have a width that decreases towards the distal end, which may allow for example to form a tip at the end of the applicator element and to obtain more precision to the application. The end face is for example of substantially triangular or elliptical shape.

La face d'extrémité peut définir, en section longitudinale dans un plan perpendiculaire à la face d'extrémité, un biseau à l'extrémité distale de l'élément d'application, ce biseau étant par exemple d'angle compris entre 6 et 65°.The end face may define, in longitudinal section in a plane perpendicular to the end face, a bevel at the distal end of the applicator element, this bevel being for example an angle between 6 and 65 °.

L'élément d'application peut présenter diverses formes en section transversale, et présenter par exemple sur au moins une portion de sa longueur une section transversale circulaire, non circulaire, polygonale ou aplatie, entre autres.The applicator element may have various cross-sectional shapes, and may for example present on at least a portion of its length a circular, non-circular, polygonal or flattened cross-section, among others.

Lorsque l'élément d'application est observé de face, dans une direction sensiblement perpendiculaire à la face d'extrémité, la largeur de la portion de l'élément d'application située au-dessus de la face d'extrémité peut être sensiblement constante, croître ou décroître en éloignement de l'extrémité distale de l'élément d'application.When the applicator element is viewed from the front, in a direction substantially perpendicular to the end face, the width of the portion of the applicator element situated above the end face may be substantially constant grow or decrease away from the distal end of the applicator element.

L'élément d'application peut comporter une ouverture, par exemple une fente, située entre la tige et la face d'extrémité.The applicator element may comprise an opening, for example a slot, located between the rod and the end face.

L'élément d'application peut présenter une surface extérieure dépourvue de cavité. En variante, l'élément d'application peut comporter un évidement, débouchant par exemple sur la face d'extrémité, cet évidement pouvant être traversant, le cas échéant. La présence de l'évidement peut permettre de constituer une réserve de produit alimentant la face d'extrémité, et peut le cas échéant conférer de la souplesse à l'élément d'application.The applicator element may have an outer surface devoid of a cavity. Alternatively, the application element may comprise a recess, opening through example on the end face, this recess can be through, if any. The presence of the recess may make it possible to constitute a supply of product supplying the end face, and may, if necessary, give flexibility to the application element.

L'élément d'application peut comporter une zone amincie formant charnière, cette zone amincie débouchant par exemple du côté opposé à la face d'extrémité. La zone amincie formant charnière peut faciliter le fléchissement de l'élément d'application au contact des lèvres ou de l'organe d'essorage, ce fléchissement s'effectuant par exemple sur une dizaine de degrés.The applicator element may comprise a hinged zone forming a hinge, this thinned zone emerging for example on the opposite side to the end face. The thinned hinge area may facilitate the bending of the applicator element in contact with the lips or the wiper member, this deflection taking place for example over a ten degrees.

L'élément d'application est avantageusement floqué, par exemple avec une même sorte de poils ou avec un mélange de poils, par exemple des poils de différentes natures et/ou de différentes longueurs.The applicator element is advantageously flocked, for example with the same kind of bristles or with a mixture of bristles, for example hairs of different natures and / or of different lengths.

L'élément d'application peut être floqué sur sensiblement la totalité de sa surface apparente. En variante, seule la surface de l'élément d'application servant à l'application du produit peut être floquée. En variante encore, l'élément d'application n'est pas floqué. Le choix de la présence ou non d'un flocage pourra s'effectuer par exemple en fonction de la rhéologie du produit.The applicator element can be flocked over substantially all of its apparent surface. Alternatively, only the surface of the application member for application of the product can be flocked. In another variant, the application element is not flocked. The choice of the presence or absence of a flocking can be made for example according to the rheology of the product.

L'élément d'application peut être magnétique ou magnétisable.The application element can be magnetic or magnetizable.

L'invention a encore pour objet, selon un autre de ses aspects, un procédé d'application d'un produit cosmétique sur la peau ou les lèvres, comportant l'étape suivante :

  • extraire d'un récipient contenant le produit à appliquer un applicateur comportant une tige munie à une extrémité d'un élément d'application, la tige étant extraite selon une direction d'extraction, l'élément d'application présentant une face d'extrémité de surface enveloppe sensiblement plane et s'étendant sensiblement parallèlement à la direction d'extraction.

Le procédé peut comporter l'étape consistant à extraire l'élément d'application au contact d'un organe d'essorage disposé dans le récipient lors de l'extraction, l'élément d'application pouvant se déformer à la traversée de l'organe d'essorage. La direction d'extraction peut être parallèle à l'axe de l'organe d'essorageThe method may comprise the step of extracting the application element in contact with a wiper member disposed in the container during extraction, the application element being deformable at the crossing of the wringing member. The extraction direction may be parallel to the axis of the wiper member

Le procédé peut comporter l'étape d'application du produit présent sur la face d'extrémité, en amenant celle-ci au contact de la peau ou des lèvres.The method may comprise the step of applying the product present on the end face, bringing it into contact with the skin or the lips.

L'invention a encore pour objet, selon un autre de ses aspects, un élément d'application pour appliquer un produit sur la peau ou les lèvres, comportant une partie de fixation sur une tige d'un applicateur, par exemple un embout à insérer dans un logement de la tige, et un corps définissant une face d'extrémité de surface enveloppe sensiblement plane et sensiblement parallèle à l'axe longitudinal de la partie de fixation, le corps ayant un axe longitudinal faisant un angle avec l'axe longitudinal de la partie de fixation. Un tel élément d'application peut présenter l'une des caractéristiques définies ci-dessus.Another subject of the invention is, according to another of its aspects, an application element for applying a product to the skin or the lips, comprising an attachment part on a rod of an applicator, for example a mouthpiece to be inserted. in a housing of the rod, and a body defining a surface end face substantially flat and substantially parallel to the longitudinal axis of the attachment portion, the body having a longitudinal axis at an angle to the longitudinal axis of the fixing part. Such an application element may have one of the characteristics defined above.

On a représenté à la figure 1 un dispositif de conditionnement et d'application 1 comportant un récipient 2 et un applicateur 3.We have shown figure 1 a packaging and application device 1 comprising a container 2 and an applicator 3.

Le récipient 2 contient un produit P qui est un rouge à lèvres liquide dans l'exemple décrit, mais on ne sort pas du cadre de la présente invention si le produit P est différent, étant par exemple un brillant à lèvres et/ou un produit de soin pour les lèvres, ou un produit de maquillage des paupières.The container 2 contains a product P which is a liquid lipstick in the example described, but it is not beyond the scope of the present invention if the product P is different, being for example a lip gloss and / or a product lip care, or an eyelid makeup product.

L'applicateur 3 comporte une tige 4 se raccordant à son extrémité proximale à un organe de préhension 5 et à son extrémité distale à un élément d'application 6, représenté plus en détail à la figure 2.The applicator 3 comprises a rod 4 connected at its proximal end to a gripping member 5 and at its distal end to an applicator element 6, shown in greater detail in FIG. figure 2 .

La tige 4 peut être d'axe longitudinal rectiligne, comme illustré, ou en variante être courbe. L'axe longitudinal de la partie distale de la tige peut correspondre alors à la direction selon laquelle s'étend l'extrémité distale de la tige.The rod 4 may be rectilinear longitudinal axis, as illustrated, or alternatively be curved. The longitudinal axis of the distal portion of the shaft may then correspond to the direction in which the distal end of the shaft extends.

L'organe de préhension 5 constitue un capuchon de fermeture étanche du récipient 2, et comporte par exemple une jupe filetée intérieurement, configurée de manière à se visser sur un col 7 du récipient 2, lequel peut comporter un filetage extérieur correspondant.The gripping member 5 constitutes a sealing cap of the container 2, and comprises for example an internally threaded skirt, configured to be screwed onto a neck 7 of the container 2, which may comprise a corresponding external thread.

Le dispositif 1 comporte en outre un organe d'essorage 8, par exemple au moins partiellement logé dans le col 7 du récipient 2, et pouvant contribuer le cas échéant à assurer l'étanchéité de la fermeture du récipient.The device 1 further comprises a wiper member 8, for example at least partially housed in the neck 7 of the container 2, and may contribute if necessary to sealing the closure of the container.

La tige 4 présente, dans l'exemple décrit, une section transversale circulaire, mais on ne sort pas du cadre de la présente invention s'il en est autrement, notamment si la section transversale de la tige 4 est ovale, elliptique ou polygonale, par exemple carrée, rectangulaire ou triangulaire. La tige 4 peut être pleine ou creuse. Le plus grand diamètre extérieur de la tige 4 peut par exemple être compris entre 3 et 6 mm, étant par exemple de 4 ou 5 mm environ.The rod 4 has, in the example described, a circular cross section, but it is not beyond the scope of the present invention if it is otherwise, especially if the cross section of the rod 4 is oval, elliptical or polygonal, for example square, rectangular or triangular. The rod 4 may be solid or hollow. The largest outer diameter of the rod 4 may for example be between 3 and 6 mm, for example about 4 or 5 mm.

Le capuchon 5 peut éventuellement, lorsque la tige 4 n'est pas de section transversale circulaire, se fixer par encliquetage ou autrement sur le récipient, sans rotation relativement à ce dernier. L'organe d'essorage 8 peut alors présenter un orifice d'essorage qui est non circulaire, de section complémentaire à celle de la tige 4.The cap 5 may optionally, when the rod 4 is not circular in cross section, snap-fastening or otherwise on the container, without rotation relative to the latter. The wiper member 8 may then have a wringing orifice which is non-circular, of complementary section to that of the rod 4.

L'organe d'essorage 8 comporte dans l'exemple illustré à la figure 1 une lèvre souple définissant un orifice d'essorage 11, de dimension adaptée à essorer l'élément d'application 6. L'organe d'essorage peut être à lèvre d'essorage ondulée ou non, fendue ou non, réglable ou non.The wiper member 8 comprises in the example illustrated in FIG. figure 1 a flexible lip defining a wiper orifice 11, of a size adapted to dewater the applicator element 6. The wiper member may be wiping wrinkle lip or not, split or not, adjustable or not.

L'élément d'application 6 comporte un corps 9 qui peut être recouvert d'un flocage 13.The application element 6 comprises a body 9 which can be covered with a flocking 13.

Le corps 9 peut être au moins partiellement, et de préférence entièrement, réalisé par moulage de matière, par exemple par moulage par injection, par exemple dans une matière choisie dans la liste suivante : matières thermoplastiques, élastomères, élastomères thermoplastiques, polyester élastomère thermoplastique tel que Hytrel® par exemple, nitrile, silicone, EPDM, SEBS, SIS, PU, EVA, PVC, PE, PET, PP, cette liste n'étant pas limitative.The body 9 may be at least partially, and preferably entirely, made by molding material, for example by injection molding, for example in a material selected from the following list: thermoplastics, elastomers, thermoplastic elastomers, polyester thermoplastic elastomer such as Hytrel ® for example, nitrile, silicone, EPDM, SEBS, SIS, PU, EVA, PVC, PE, PET, PP, this list not being limiting.

Le corps 9 peut être réalisé au moins partiellement dans un matériau plus souple qu'un matériau dans lequel est réalisée la tige 4.The body 9 can be made at least partially in a softer material than a material in which the rod 4 is made.

L'élément d'application 6 peut être magnétique le cas échéant, le corps 9 pouvant par exemple comporter des particules ayant une susceptibilité magnétique non nulle.The application element 6 may be magnetic if necessary, the body 9 may for example comprise particles having a non-zero magnetic susceptibility.

La plus grande largeur de l'élément d'application, mesurée perpendiculairement à l'axe longitudinal de la tige, peut être inférieure, voire strictement inférieure, à la plus grande largeur de la tige mesurée perpendiculairement à l'axe longitudinal X de la tige.The greatest width of the application element, measured perpendicularly to the longitudinal axis of the rod, may be smaller or even less than the greatest width of the rod measured perpendicular to the longitudinal axis X of the rod. .

Le corps 9 de l'élément d'application peut être moulé d'une seule pièce avec un embout de fixation non apparent sur les figures 1 à 3, destiné à être reçu dans un logement correspondant de la tige 4. Cet embout a, dans l'exemple considéré, un axe longitudinal qui est confondu avec celui de la partie distale de la tige.The body 9 of the applicator element may be molded in one piece with a non-visible fastening tip on the Figures 1 to 3 , intended to be received in a corresponding housing of the rod 4. This tip has, in the example, a longitudinal axis which coincides with that of the distal portion of the rod.

L'élément d'application 6 peut être fixé à la tige 4 par collage, soudure, insertion à force, encliquetage, sertissage ou vissage. En variante, le corps 9 est réalisé d'une seule pièce avec la tige 4, par exemple dans la même matière ou dans des matériaux différents, par exemple par bi-injection.The application element 6 can be fixed to the rod 4 by gluing, welding, insertion by force, latching, crimping or screwing. Alternatively, the body 9 is made in one piece with the rod 4, for example in the same material or in different materials, for example by bi-injection.

La tige 4 peut comporter, le cas échéant, une zone flexible favorisant sa déformation lors de l'application et/ou lors du retrait du récipient, ou au contraire en être dépourvue.The rod 4 may include, where appropriate, a flexible zone promoting its deformation during application and / or during removal of the container, or otherwise be devoid thereof.

L'élément d'application 6 présente une portion apparente 20 qui prolonge inférieurement la tige 4, comme on peut le voir sur la figure 2, qui s'étend selon un axe longitudinal Y, qui est par exemple rectiligne et fait un angle α avec l'axe longitudinal X de la portion distale 21 de la tige 4. L'angle α est par exemple compris entre 5 et 45 °.The applicator element 6 has an apparent portion 20 which extends lowerly on the rod 4, as can be seen in FIG. figure 2 , which extends along a longitudinal axis Y, which is for example rectilinear and makes an angle α with the longitudinal axis X of the distal portion 21 of the rod 4. The angle α is for example between 5 and 45 ° .

L'élément d'application 6 présente une face d'extrémité 25 et une surface latérale 26.The applicator element 6 has an end face 25 and a lateral surface 26.

L'organe de préhension 5 peut comporter, le cas échéant, au moins une zone (non représentée) de réception d'un doigt, par exemple une alvéole ou méplat, qui peut s'étendre par exemple du côté de la face d'extrémité 25. Une telle zone de réception peut faciliter le repérage de l'orientation de l'élément d'application.The gripping member 5 may comprise, where appropriate, at least one zone (not shown) for receiving a finger, for example a cell or flat, which may extend for example on the side of the end face. 25. Such a reception area can facilitate the identification of the orientation of the application element.

La section transversale de l'élément d'application 6, sur sa portion 30 située au-dessus de la face d'extrémité 25, est par exemple circulaire comme illustré à la figure 17 mais pourrait être autre, par exemple oblongue ou polygonale, entre autres.The cross section of the applicator element 6, on its portion 30 situated above the end face 25, is for example circular as illustrated in FIG. figure 17 but could be other, for example oblong or polygonal, among others.

La largeur ω de l'élément d'application sur la portion 30 située au-dessus de la face d'extrémité 25, mesurée en vue de face comme sur la figure 3, peut être sensiblement constante comme illustré sur cette figure ou varier, par exemple croître en direction de l'extrémité distale 33 de l'élément d'application, comme illustré à la figure 12.The width ω of the applicator element on the portion 30 situated above the end face 25, measured in front view as on the figure 3 , may be substantially constant as illustrated in this figure or vary, for example grow in the direction of the distal end 33 of the applicator element, as illustrated in FIG. figure 12 .

La face d'extrémité 25 peut présenter une largeur ω'qui décroît en direction de l'extrémité distale 33, par exemple selon un contour elliptique, lequel peut être symétrique par rapport à un plan médian, comme illustré.The end face 25 may have a width ω which decreases towards the distal end 33, for example in an elliptical outline, which may be symmetrical with respect to a median plane, as illustrated.

Dans l'exemple de la figure 2, l'extrémité distale 33 forme une pointe arrondie. La face d'extrémité 25 peut intercepter l'axe longitudinal Y de l'élément d'application 9 avec un angle β qui est par exemple le même que l'angle formé à l'extrémité distale 33 entre la face d'extrémité 25 et la surface latérale 26, dans un plan de coupe longitudinale de l'élément d'application perpendiculaire à la face d'extrémité. L'angle β est par exemple égal à l'angle α entre les axes X et Y.In the example of the figure 2 , the distal end 33 forms a rounded tip. The end face 25 can intercept the longitudinal axis Y of the application element 9 with an angle β which is for example the same as the angle formed at the distal end 33 between the end face 25 and the lateral surface 26, in a longitudinal sectional plane the application element perpendicular to the end face. The angle β is for example equal to the angle α between the X and Y axes.

La distance k entre la face d'extrémité 25 et l'axe longitudinal X dépend de la longueur de la portion 20, de sa forme et de l'inclinaison relativement à l'axe X.The distance k between the end face 25 and the longitudinal axis X depends on the length of the portion 20, its shape and the inclination relative to the axis X.

La distance l sur laquelle la face d'extrémité 25 s'étend parallèlement à l'axe X est par exemple supérieure ou égale à 2 mm, mieux à 3 ou 4 mm.The distance 1 on which the end face 25 extends parallel to the axis X is for example greater than or equal to 2 mm, more preferably 3 or 4 mm.

Comme illustré à la figure 16, l'angle γ entre la surface enveloppe de la face d'extrémité 25 et l'axe longitudinal X, dans au moins un plan de coupe contenant l'axe longitudinal, est nul ou relativement faible, étant inférieur ou égal à 10°, de sorte que la face d'extrémité 25 s'étend sensiblement parallèlement à l'axe longitudinal X de la portion distale 21 de la tige 4.As illustrated in figure 16 the angle γ between the envelope surface of the end face 25 and the longitudinal axis X, in at least one cutting plane containing the longitudinal axis, is zero or relatively small, being less than or equal to 10 °, so that the end face 25 extends substantially parallel to the longitudinal axis X of the distal portion 21 of the rod 4.

La face d'extrémité 25 peut être orientée sensiblement parallèlement à la direction selon laquelle la partie distale 21 de la tige 4 est extraite du récipient 2, direction qui coïncide avec l'axe de l'organe d'essorage 8, et la face d'extrémité 25 peut être essuyée par le bord de la lèvre d'essorage 8 d'une manière relativement poussée, ce qui conduit à l'absence de goutte de produit en excès sur la face d'extrémité 25.The end face 25 may be oriented substantially parallel to the direction in which the distal portion 21 of the rod 4 is extracted from the container 2, which direction coincides with the axis of the wiper member 8, and the face of the end 25 can be wiped by the edge of the wiper lip 8 in a relatively high manner, which leads to the absence of excess product drop on the end face 25.

La face d'extrémité 25 est de surface enveloppe E sensiblement plane, celle-ci étant par exemple plane, légèrement concave ou convexe.The end face 25 is of substantially flat envelope surface E, the latter being for example flat, slightly concave or convex.

On a illustré à la figure 22 une surface enveloppe E légèrement convexe. La flèche ε définie comme étant la distance du sommet S de la surface enveloppe à une droite D joignant deux régions diamétralement opposées du contour de la face extrémité, est inférieure ou égale à 1,2 mm, mieux 0,5 mm. Il en est de même en cas de surface légèrement concave, la flèche ε étant mesurée entre le fond de la cavité et la droite D.We illustrated at the figure 22 an envelope surface E slightly convex. The arrow ε defined as being the distance from the vertex S of the envelope surface to a straight line D joining two diametrically opposite regions of the contour of the end face is less than or equal to 1.2 mm, more preferably 0.5 mm. It is the same in case of slightly concave surface, the arrow ε being measured between the bottom of the cavity and the right D.

Lors de l'utilisation, la face d'extrémité 25 essorée peut être amenée au contact des lèvres L, comme illustré à la figure 4. La surface latérale 26 peut également, le cas échéant, servir à l'application.In use, the dewatered end face can be brought into contact with the lips L, as illustrated in FIG. figure 4 . The side surface 26 may also, if appropriate, be used for the application.

On peut apporter diverses modifications à l'élément d'application 6 sans sortir du cadre de la présente invention.Various modifications can be made to the application element 6 without departing from the scope of the present invention.

La surface latérale 26 peut notamment être non cylindrique ou non tronconique.The lateral surface 26 may in particular be non-cylindrical or non-frustoconical.

Dans l'exemple de la figure 5, l'élément d'application 6 est aplati ou effilé à son extrémité, formant un bec 40 qui s'étend par exemple sensiblement parallèlement à l'axe X. Le bec 40 peut être de section transversale aplatie dans un plan de coupe perpendiculaire à l'axe X ou à l'axe longitudinal de l'élément d'application 6.In the example of the figure 5 , the applicator element 6 is flattened or tapered at its end, forming a spout 40 which for example extends substantially parallel to the axis X. The spout 40 may be of flattened cross-section in a plane of section perpendicular to the axis X or to the longitudinal axis of the applicator element 6.

Le bec 40 peut s'étendre sur une distance b plus ou moins longue, comme on peut le voir sur les figures 5 et 6, et la face d'extrémité 25 peut être définie par une proportion plus ou moins grande de ce bec 40.The spout 40 can extend over a distance b more or less long, as can be seen on the Figures 5 and 6 , and the end face 25 may be defined by a greater or lesser proportion of this nozzle 40.

La face d'extrémité 25 peut être définie au moins sur la moitié de sa longueur mesurée parallèlement à l'axe X par le bec 40, voire sur les trois quarts de sa longueur par ce bec 40.The end face 25 can be defined at least over half of its length measured parallel to the axis X by the spout 40, or even three quarters of its length by this spout 40.

Le bec 40 peut être suffisamment mince pour fléchir à l'application, le cas échéant, l'épaisseur moyenne f pouvant être relativement faibleThe spout 40 may be thin enough to flex on application, if necessary, the average thickness f may be relatively low

La face d'extrémité 25 peut être plus large que la portion supérieure 30, comme on le voit à la figure 8, la face d'extrémité 25 présentant par exemple une largeur ω' qui croît puis décroît en se rapprochant de l'extrémité distale 33.The end face 25 may be wider than the upper portion 30, as seen in FIG. figure 8 , the end face 25 having for example a width ω 'which increases and then decreases when approaching the distal end 33.

Dans l'exemple des figures 7 et 8, la face d'extrémité 25 est formée par un bec aplati 40 qui se raccorde en faisant un angle δ avec l'axe longitudinal de la portion supérieure 30, cette dernière ayant par exemple un axe longitudinal qui est rectiligne et qui fait un angle α avec l'axe longitudinal X de la partie distale 21 de la tige 4.In the example of Figures 7 and 8 the end face 25 is formed by a flattened nose 40 which is connected at an angle δ with the longitudinal axis of the upper portion 30, the latter having for example a longitudinal axis which is rectilinear and which makes an angle α with the longitudinal axis X of the distal portion 21 of the rod 4.

Dans la variante des figures 9 et 10, la face d'extrémité 25 présente un contour sensiblement triangulaire, en vue de face.In the variant of Figures 9 and 10 , the end face 25 has a substantially triangular contour, in front view.

Il en est de même dans la variante des figures 11 et 12, où la portion supérieure 30 de l'élément d'application présente une largeur décroissant en direction de la tige 4.It is the same in the variant of Figures 11 and 12 , where the upper portion 30 of the applicator element has a decreasing width in the direction of the rod 4.

Dans la variante des figures 13 et 14, l'élément d'application 6 comporte un évidement 50 qui débouche sur la face d'extrémité 25. La surface enveloppe E de la face d'extrémité 25 est dans cet exemple un plan qui s'appuie sur le pourtour de l'évidement 50, ce plan étant parallèle à l'axe X.In the variant of Figures 13 and 14 , the application element 6 comprises a recess 50 which opens on the end face 25. The envelope surface E of the end face 25 is in this example a plane which rests on the periphery of the recess 50, this plane being parallel to the axis X.

L'élément d'application 6 présente par exemple un bec 40 et l'évidement 50 traverse ce bec 40.The applicator element 6 for example has a spout 40 and the recess 50 passes through this spout 40.

L'épaisseur du bec 40 peut par exemple décroître en direction de l'extrémité distale 33.The thickness of the nose 40 may, for example, decrease towards the distal end 33.

L'évidement 50 se présente par exemple sous la forme d'une ouverture relativement étroite, allongée selon l'axe longitudinal du bec 40, comme on peut le voir sur la figure 13. Dans une variante non illustrée, l'évidement 50 est non traversant. Le cas échéant, l'évidement 50 peut se prolonger sur la portion 30 située au dessus de la face d'extrémité 25.The recess 50 is, for example, in the form of a relatively narrow opening, elongated along the longitudinal axis of the spout 40, as can be seen in FIG. figure 13 . In a variant not illustrated, the recess 50 is non-traversing. The case where appropriate, the recess 50 may extend over the portion 30 situated above the end face 25.

On voit sur la figure 14 que l'élément d'application 6 peut comporter une partie de fixation agencée pour se fixer dans ou sur la tige, par exemple un embout 81 inséré dans un logement de la tige.We see on the figure 14 that the applicator element 6 may comprise an attachment portion arranged to be fixed in or on the rod, for example a tip 81 inserted in a housing of the rod.

L'élément d'application 6 peut comporter, comme illustré à la figure 15, une zone amincie 55 formant charnière, créée par un rétrécissement de la section transversale de l'élément d'application. Cette zone 55 formant charnière est située dans l'exemple de la figure 15 sur la portion supérieure 30 de l'élément d'application, définissant un évidement 56 du côté opposé à la face d'extrémité 25.The application element 6 may comprise, as illustrated in FIG. figure 15 a hinged area 55 formed by a narrowing of the cross-section of the applicator element. This hinge area 55 is located in the example of the figure 15 on the upper portion 30 of the applicator element, defining a recess 56 on the side opposite to the end face 25.

La figure 19 représente un élément d'application ayant une surface latérale 26 divergeant en direction de la face d'extrémité 25.The figure 19 represents an applicator element having a lateral surface 26 diverging towards the end face 25.

Dans l'exemple de la figure 20, l'élément d'application comporte une arête 51 du côté opposé à la face d'extrémité 25, l'arête 51 étant par exemple située à la jonction de deux faces 52 sensiblement planes.In the example of the figure 20 , the applicator element comprises an edge 51 on the opposite side to the end face 25, the edge 51 being for example located at the junction of two substantially planar faces 52.

On a illustré à la figure 21 la possibilité pour la portion 30 de l'élément d'application, située entre la face d'extrémité 25 et la tige 4, de présenter une ouverture 58, par exemple sous la forme d'une fente.We illustrated at the figure 21 the possibility for the portion 30 of the applicator element, located between the end face 25 and the rod 4, to have an opening 58, for example in the form of a slot.

Bien entendu, l'invention n'est pas limitée aux exemples illustrés. Les particularités de réalisation des exemples illustrés peuvent être combinées au sein de variantes non représentées.Of course, the invention is not limited to the illustrated examples. The particular features of the examples illustrated can be combined within variations not shown.

L'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.The expression " having one" shall be understood as being synonymous with " having at least one ", unless the opposite is specified.
