Dans l'état de la technique il est connu du document EP-0504050 un dispositif de conditionnement et d'application de produit solidifié présenté sur un piston à l'intérieur d'une cheminée, la distribution du produit s'effectuant par une translation du piston, et donc du produit solidifié en direction d'une ouverture de distribution de la cheminée. Pour la distribution du produit, une extrémité du produit solidifié destinée à être mise en contact direct avec la surface de peau à enduire est présentée dépassant de l'ouverture de distribution.In the state of the art, it is known from the document EP-0504050 a device for packaging and applying solidified product presented on a piston inside a chimney, the distribution of the product being effected by a translation of the piston, and therefore of the solidified product towards a dispensing opening from the fireplace. For dispensing the product, an end of the solidified product to be brought into direct contact with the skin surface to be coated is presented extending beyond the dispensing opening.

Cette translation du piston est obtenue par un actionnement d'un curseur dépassant du pourtour extérieur de la cheminée. A cet effet, le curseur traverse une rainure formée dans la cheminée afin de coopérer avec le piston de telle sorte qu'une translation du curseur entraîne une translation identique du produit solidifié dans la cheminée. Entre deux utilisations, un capuchon est monté autour de l'ouverture de distributionThis translation of the piston is obtained by an actuation of a slider protruding from the outer circumference of the chimney. For this purpose, the slider passes through a groove formed in the chimney to cooperate with the piston so that a translation of the slider causes an identical translation of the solidified product in the chimney. Between uses, a cap is mounted around the dispensing opening

Un autre dispositif de conditionnement et d'application de produit solidifié présenté sur un piston à l'intérieur d'une cheminée est connu du document WO 98/47403 .Another device for packaging and applying solidified product presented on a piston inside a chimney is known from the document WO 98/47403 .

La cheminée comporte dans ces exemples de réalisation une ouverture de distribution sensiblement ovale. Le produit solidifié est alors également de section transversale ovale. Ils sont particulièrement conçus pour l'application de produit déodorant sous les aisselles. Ces dispositifs ne sont pas adaptés à des surfaces non continues telle qu'une nappe de fibres kératiniques. Ils sont par ailleurs encombrants, et les mécanismes pour garantir l'étanchéité au stockage du produit est difficile à obtenir de manière fiable.The chimney comprises in these embodiments a substantially oval distribution opening. The solidified product is then also of oval cross-section. They are specially designed for the application of underarm deodorant product. These devices are not suitable for non-continuous surfaces such as a sheet of keratinous fibers. They are also cumbersome, and the mechanisms to ensure the tightness of storage of the product is difficult to obtain reliably.

On connaît par ailleurs du document US-2887117 un applicateur de produit sur les cheveux comportant des picots au niveau de son orifice de distribution, les picots étant configurés pour permettre un massage du cuir chevelu, et par ailleurs fournir un moyen d'accrochage d'un organe de fermeture de cet orifice de distribution.It is also known from the document US 2887117 a product applicator on the hair having spikes at its dispensing orifice, the spikes being configured to allow a massage of the scalp, and also provide a means for attaching a closure member of this dispensing orifice .

Un but de la présente invention est donc de fournir un dispositif de conditionnement et d'application de produit permettant de surmonter au moins un des inconvénients susmentionnés.An object of the present invention is therefore to provide a device for packaging and product application to overcome at least one of the aforementioned drawbacks.

Un autre but de la présente invention est encore de fournir un dispositif de conditionnement qui soit compact, et qui puisse être manipulé aisément d'une seule main, l'autre main pouvant par exemple servir à présenter un miroir en regard des yeux pour contrôler l'application de produit.Another object of the present invention is to provide a packaging device which is compact and which can be easily handled with one hand, the other hand being able for example to be used to present a mirror facing the eyes to control the product application.

Un but de la présente invention est encore de fournir un dispositif pouvant présenter une ouverture de distribution aux dimensions adaptées à la destination d'application du produit contenu.An object of the present invention is also to provide a device that can have a distribution opening with dimensions adapted to the application destination of the contained product.

La présente invention a donc pour objet un dispositif de conditionnement et d'application comme défini dans les revendications.The present invention therefore relates to a packaging and application device as defined in the claims.

Ainsi, le moyen d'entraînement étant compris dans le maître couple de l'embase, le dispositif est avantageusement compact.Thus, the drive means being included in the master torque of the base, the device is advantageously compact.

Par exemple, la paroi latérale de la cheminée peut comporter une section transversale interne présentant une portion concave vers l'intérieur et une portion convexe vers l'intérieur, l'embase présentant une section transversale externe convexe vers l'extérieur.For example, the side wall of the chimney may include an inner cross section having a concave portion inwardly and a convex portion inwardly, the base having an outwardly convex outer cross section.

Le plateau peut être en contact étanche avec la paroi latérale de la cheminée, dans une position au moins du plateau dans la cheminée. En particulier, le plateau est en contact étanche avec le pourtour intérieur de la paroi latérale lorsqu'il est en position basse dans la cheminée et que le produit ne dépasse pas de l'ouverture de distribution. Cette disposition est notamment avantageuse lorsque le conditionnement en produit du dispositif est réalisé via l'ouverture de distribution.The tray may be in sealing contact with the side wall of the chimney, in at least one position of the tray in the chimney. In particular, the plate is in sealing contact with the inner periphery of the side wall when it is in the lower position in the chimney and the product does not exceed the dispensing opening. This arrangement is particularly advantageous when the product packaging of the device is performed via the dispensing opening.

En plus, le dispositif comporte un couvercle configuré pour coopérer avec l'embase. Ainsi, entre deux utilisations, le produit est protégé dans le volume délimité par la cheminée, le plateau et le couvercle. Avantageusement, le couvercle assure une fermeture étanche de l'embase, le produit, la cheminée et le plateau étant disposés à l'intérieur de ce volume étanche.In addition, the device comprises a lid configured to cooperate with the base. Thus, between two uses, the product is protected in the volume defined by the chimney, the tray and the lid. Advantageously, the cover provides a sealed closure of the base, the product, the chimney and the tray being disposed within this sealed volume.

Le moyen d'entraînement comporte un bouton poussoir qui est circonscrit au maître-couple de l'embase. Cette disposition favorise la compacité du dispositif. Le bouton poussoir est disposé entre la paroi latérale de la cheminée et l'embase, et plus particulièrement entre la zone de la paroi latérale présentant la portion convexe vers l'intérieur et l'embase.The drive means comprises a push button which is circumscribed to the master torque of the base. This arrangement promotes the compactness of the device. The push button is disposed between the side wall of the chimney and the base, and more particularly between the area of the side wall having the convex portion inwardly and the base.

Le moyen d'entraînement peut être coulissé dans une rainure de la cheminée. Cette rainure peut avantageusement être réalisée au travers de la paroi latérale, dans une portion axiale de cette paroi entourée par l'embase. Ainsi la rainure est masquée par l'embase. De plus, dans les cas où le moyen d'entraînement comporte un bouton poussoir, ce dernier dépasse longitudinalement de l'embase, le moyen d'entraînement comportant une portion longitudinale s'étendant dans l'embase et présentant un ergot traversant la rainure. Dans ce cas, la rainure peut être formée dans une portion longitudinale de la cheminée à distance de la portion longitudinale dans laquelle le plateau peut être déplacé.The drive means can be slid into a groove in the chimney. This groove may advantageously be made through the side wall, in an axial portion of this wall surrounded by the base. Thus the groove is hidden by the base. In addition, in cases where the drive means comprises a push button, the latter protrudes longitudinally from the base, the drive means comprising a longitudinal portion extending into the base and having a lug passing through the groove. In this case, the groove may be formed in a longitudinal portion of the chimney at a distance from the longitudinal portion in which the tray can be moved.

A cet effet, l'ergot du moyen d'entraînement peut coopérer avec une extrémité distale d'une tige dressée depuis un fond du plateau, la tige s'étendant dans la cheminé en direction d'un fond de l'embase.For this purpose, the lug of the drive means can cooperate with a distal end of a rod raised from a bottom of the tray, the rod extending in the path towards a bottom of the base.

Le bouton poussoir peut comporter une extrémité libre disposée sensiblement au niveau du plateau, la rainure étant configurée pour autoriser le déplacement du plateau jusqu'au niveau de l'ouverture de la cheminée. Lorsque le plateau est en position haute et que le plateau se situe sensiblement au niveau de l'ouverture de distribution, l'extrémité libre du bouton poussoir est situé autour de l'ouverture de distribution sans pour autant dépasser du niveau dans lequel elle s'étend.The push button may comprise a free end disposed substantially at the level of the tray, the groove being configured to allow the displacement of the tray to the level of the opening of the chimney. When the tray is in the up position and the tray is substantially at the dispensing opening, the free end of the push button is located around the dispensing opening without exceeding the level in which it is located. extends.

Avantageusement, la rainure comporte deux butées axiales de manière à déterminer la course axiale maximale tolérée pour le plateau. Cette distance entre les deux butées axiales correspond sensiblement à la hauteur de produit qui est par exemple disposée sur le plateau.Advantageously, the groove comprises two axial stops so as to determine the maximum axial travel allowed for the plate. This distance between the two axial stops corresponds substantially to the product height which is for example arranged on the plate.

Par exemple, un ratio de la hauteur de produit avant la première utilisation sur la hauteur totale du dispositif peut être compris entre 0,3 et 0,8, et préférentiellement entre 0,4 et 0,6, avantageusement de l'ordre de 0,5.For example, a ratio of the product height before the first use to the total height of the device may be between 0.3 and 0.8, and preferably between 0.4 and 0.6, advantageously of the order of 0 5.

Selon un mode de réalisation particulier, le plateau forme un siège pour recevoir le produit qui peut être sous forme de stick. Par stick, on entend un produit qui conserve sa forme prédéterminée en l'absence de contrainte, à température ambiante et à pression atmosphérique. Un produit conditionné sous forme de stick est autoporteur, de préférence pendant au moins 60 secondes. Généralement, de tels sticks sont obtenus par coulage à chaud du produit ou encore par extrusion.According to a particular embodiment, the tray forms a seat for receiving the product which may be in the form of a stick. By stick is meant a product that retains its predetermined shape in the absence of stress, at room temperature and at atmospheric pressure. A packaged product in the form of a stick is self-supporting, preferably for at least 60 seconds. Generally, such sticks are obtained by hot casting of the product or by extrusion.

Avantageusement, le stick de produit peut être une composition solide, en particulier délitable à sec. Par délitable à sec, on désigne une composition apte, à température ambiante, à former un dépôt adhérent et gainant sur un substrat, notamment des fibres kératiniques, et plus particulièrement des cils, lorsqu'ils sont respectivement mis en contact direct l'un avec l'autre, sans nécessiter de préparation préalable, et en l'occurrence sans nécessiter de mise en contact préalable de la composition avec une phase aqueuse, par opposition aux mascaras pains qui sont délitables à l'eau et doivent au préalable être solubilisés partiellement pour être appliqués sur les fibres kératiniques et former un dépôt adhérent et gainant. La composition délitable à sec selon l'invention peut être prélevée, transférée et étalée.Advantageously, the product stick may be a solid composition, in particular dry-crackable. Dry-blast means a composition suitable for ambient temperature, to form an adherent deposit and sheathing on a substrate, in particular keratin fibers, and more particularly eyelashes, when they are placed in direct contact with each other, without the need for prior preparation, and the occurrence without requiring prior contact of the composition with an aqueous phase, as opposed to mascaras breads which are water-soluble and must first be solubilized partially to be applied to the keratin fibers and form an adherent deposit and sheathing. The dry-blast composition according to the invention can be removed, transferred and spread.

Par exemple, le stick de produit peut être une composition solide ayant une dureté comprise entre 500 à 18200 Pa, en particulier comprise entre 900 à 10000 Pa, et plus particulièrement entre 1800 à 8200 Pa. Une telle dureté permet l'obtention d'une composition qui est suffisamment rigide pour se présenter sous forme de stick tout en ayant une texture assez « molle » pour permettre une application aisée sur les cils, notamment un dépôt de matière par mise en contact direct avec les cils, sans exercer une pression sur la frange de cils.For example, the product stick may be a solid composition having a hardness of between 500 and 18200 Pa, in particular between 900 and 10,000 Pa, and more particularly between 1800 and 8200 Pa. Such hardness makes it possible to obtain a composition which is rigid enough to be in the form of a stick while having a fairly "soft" texture to allow easy application to the eyelashes, in particular a deposit of material by placing it in direct contact with the eyelashes, without exerting pressure on the bangs of eyelashes.

La méthode utilisée pour déterminer la dureté d'une composition cosmétique conforme à l'invention est celle dite « du fil à couper le beurre ». A cet effet, on prépare un stick de ladite composition dont la dureté doit être déterminée. Le stick est obtenu par coulage d'une composition dans un moule aluminium placé 45 minutes à -28°C, puis démoulé et conditionné dans un article de conditionnement, en particulier un stylo, et conservé ensuite à une température de 20 °C pendant les 24 heures précédant la mesure. Un fil rigide de diamètre 250 µm en tungstène est avancé relativement au stick à une vitesse de 100 mm/min, de manière à couper transversalement le stick à l'aide dudit fil. La dureté mesurée correspond à la force maximale de cisaillement exercée par le fil sur le stick à 20 °C, cette force étant mesurée au moyen d'un dynamomètre DFGS2 commercialisé par la société INDELCO-CHATILLON. La mesure est reproduite 6 fois. La moyenne des 6 valeurs lues au moyen du dynamomètre mentionné ci-dessus, notée Y, est donnée en grammes. Cette moyenne est convertie en Pascal par l'équation suivante pour obtenir la valeur de dureté du stick :

  • (Y x 10-3 x 9,8) / surface de la section transversale du stick (en m2)
The method used to determine the hardness of a cosmetic composition according to the invention is that known as "butter-cutting thread". For this purpose, a stick of said composition is prepared, the hardness of which must be determined. The stick is obtained by casting a composition in an aluminum mold placed for 45 minutes at -28 ° C., then demolded and packaged in a packaging article, in particular a pen, and then stored at a temperature of 20 ° C. during 24 hours before the measurement. A rigid wire 250 micron diameter tungsten is advanced relative to the stick at a speed of 100 mm / min, so as to cut the stick transversely using said wire. The hardness measured corresponds to the maximum shear force exerted by the wire on the stick at 20 ° C., this force being measured by means of a DFGS2 dynamometer marketed by INDELCO-CHATILLON. The measurement is reproduced 6 times. The average of the 6 values read using the dynamometer mentioned above, denoted Y, is given in grams. This average is converted to Pascal by the following equation to obtain the hardness value of the stick:
  • (Y x 10-3 x 9.8) / cross sectional area of the stick (in m 2 )

Dans le cas d'un stick cylindrique de section circulaire, la surface de la section transversale est égale à TT x R2, R étant le rayon du stick exprimé en mètres.In the case of a cylindrical stick of circular section, the surface of the cross section is equal to TT x R2, where R is the radius of the stick expressed in meters.

De préférence, la dureté des compositions selon la présente invention est telle que les compositions s'auto-supportent et par ailleurs puissent être facilement désintégrées pour former un dépôt à la surface des fibres kératiniques lorsqu'elles sont amenées à leur contact.Preferably, the hardness of the compositions according to the present invention is such that the compositions are self-supporting and moreover can be easily disintegrated to form a deposit on the surface of the keratinous fibers when they are brought into contact with them.

Par exemple, le stick de produit peut avoir une forme de bâton, comportant un axe longitudinal. Ce stick peut comporter une portion tubulaire et en particulier cylindrique.For example, the product stick may have a stick shape, having a longitudinal axis. This stick may comprise a tubular portion and in particular cylindrical.

Le plateau peut être perméable au produit, notamment lorsque le produit disposé sur ce plateau se présente sous forme de stick, et qu'il y a été déposé par coulage à chaud, la solidification du stick ayant lieu in situ dans la cheminée. Dans ce cas, la cheminée comporte avantageusement une deuxième ouverture, axialement opposée à la première ouverture, de manière à permettre ce coulage du produit dans le logement. Le dispositif est alors présenté « tête en bas » sous des moyens d'injection du produit.The tray may be permeable to the product, especially when the product disposed on the tray is in the form of a stick, and it was deposited by hot casting, the solidification of the stick occurring in situ in the chimney. In this case, the chimney advantageously comprises a second opening, axially opposite to the first opening, so as to allow this casting of the product in the housing. The device is then presented "upside down" under the product injection means.

L'ouverture de distribution de la cheminée peut être obturée avant la première utilisation. Cette disposition est notamment utile lorsque le produit est coulé dans son logement depuis une ouverture opposée à l'ouverture de distribution. Pour obturée cette ouverture de distribution, il est par exemple prévu un opercule. Dans le cas où l'opercule est rigide, il permet également de mettre en forme une extrémité libre du produit coulé.The distribution opening of the chimney can be closed before the first use. This arrangement is particularly useful when the product is poured into its housing from an opening opposite to the dispensing opening. For closure of this dispensing opening, there is for example provided a cap. In the case where the lid is rigid, it also makes it possible to shape a free end of the cast product.

La cheminée peut s'évaser en direction de son ouverture de distribution. La paroi latérale intérieure de la cheminée est ainsi plus facile à démouler. Dans ce cas, dès lors que le plateau est déplacé de sa position initiale, un espace se crée entre le pourtour extérieur du plateau et le pourtour intérieur de la paroi latérale. Le déplacement peut ainsi être effectué sans que des contraintes de frottement viennent l'empêcher.The chimney can flare towards its dispensing opening. The inner side wall of the chimney is thus easier to unmold. In this case, as soon as the plate is moved from its initial position, a space is created between the outer periphery of the plate and the inner periphery of the side wall. The displacement can thus be carried out without friction constraints preventing it.

L'ouverture de distribution de la cheminée peut présenter une section interne de pourtour sensiblement identique à celui de la section transversale interne de la cheminée. Elle présente alors une portion concave vers l'intérieur et une portion convexe vers l'intérieur. Ainsi le produit présenté sur le plateau est déplacé au travers de l'ouverture de distribution sans être modifiée par cette dernière. Le produit distribué, s'il se présente sous forme de pain présente alors également une portion concave et une portion convexe.The opening of distribution of the chimney may have an inner section around substantially identical to that of the internal cross section of the chimney. It then has a concave portion inwardly and a convex portion inwardly. Thus the product presented on the tray is moved through the dispensing opening without being modified by the latter. The product dispensed, if it is in the form of bread then also has a concave portion and a convex portion.

Cette forme d'ouverture pour la distribution de produit est notamment adaptée pour venir au contact d'une frange de cils. En effet, les cils étant implantés à la bordure de la paupière, cette paupière suivant le contour du globe oculaire, la base des cils est donc située sur une courbe. Avec une telle forme d'ouverture, il est ainsi possible d'enduire une rangée de cils en les enduisant de produit depuis sensiblement le même point relativement à leur base respective. Le maquillage est ainsi uniforme.This form of opening for dispensing product is particularly adapted to come into contact with an eyelash fringe. Indeed, eyelashes being implanted at the edge of the eyelid, this eyelid along the contour of the eyeball, the base of the eyelashes is located on a curve. With such an opening shape, it is thus possible to coat a row of eyelashes by coating them with product from substantially the same point relative to their respective base. The makeup is thus uniform.

Des éléments de séparation/ peignage peuvent être dressés à la périphérie de l'ouverture de distribution, ces éléments de séparation/ peignage s'étendant parallèlement à un axe de translation du plateau dans la cheminée. Ils sont configurés de manière à venir en engagement avec les fibres kératiniques pour les séparer/peigner simultanément et/ou postérieurement à l'application du produit sur les fibres au moyen du produit distribué au niveau de l'ouverture de distribution. Les éléments de séparation/peignage sont avantageusement effilés, notamment sous forme de dents ou de poils pour permettre un peignage et ou une séparation efficace des fibres kératiniques, et en particulier des cils.Separation / combing elements may be erected at the periphery of the dispensing opening, these separating / combing elements extending parallel to an axis of translation of the plate in the chimney. They are configured so as to come into engagement with the keratin fibers to separate / comb them simultaneously and / or after the application of the product to the fibers by means of the product dispensed at the level of the dispensing aperture. The separating / combing elements are advantageously tapered, in particular in the form of teeth or bristles, to allow efficient combing and / or separation of the keratinous fibers, and in particular eyelashes.

La portion concave vers l'intérieur et la portion convexe vers l'intérieur peuvent être sensiblement superposables, et disposées en regard l'une de l'autre de façon à ce que l'ouverture de distribution forme une fente courbe. Une telle disposition permet notamment de respecter l'implantation d'une frange de cils à la bordure d'une paupière.The inwardly concave portion and the inwardly convex portion may be substantially superimposable, and disposed facing each other so that the dispensing opening forms a curved slot. Such an arrangement makes it possible in particular to respect the implantation of an eyelash fringe at the edge of an eyelid.

L'invention a également pour objet un procédé d'application d'un produit sur les cils au moyen d'un dispositif selon l'invention, dans lequel le dispositif est déplacé selon un trajet défini dans un même plan sensiblement perpendiculaire à la cornée et parallèle au plan du nez. Cet trajet est en particulier celui de l'orifice de distribution qui est alors amené tangentiellement à la cornée au contact de la base d'une rangée de cils, l'orifice de distribution étant ensuite déplacé le long de la rangée de cils en direction de leur extrémité libre respective, en contraignant les cils contre l'ouverture de distribution. Le déplacement du dispositif peut être fait selon une boucle itérative définie dans un ou plusieurs plan(s) sensiblement perpendiculaire(s) à la cornée et parallèle(s) au plan du nez, en fonction du maquillage recherché.The invention also relates to a method for applying a product to the eyelashes by means of a device according to the invention, in which the device is moved along a path defined in the same plane substantially perpendicular to the cornea and parallel to the plane of the nose. This path is in particular that of the dispensing orifice which is then brought tangentially to the cornea in contact with the base of a row of eyelashes, the dispensing orifice then being moved along the row of eyelashes in the direction of their respective free end, by constraining the eyelashes against the dispensing opening. The displacement of the device may be done according to an iterative loop defined in one or more plane (s) substantially perpendicular (s) to the cornea and parallel (s) to the plane of the nose, depending on the desired makeup.

La figure 1 représente un dispositif de conditionnement et d'application 1 selon l'invention comportant une embase 2 sur laquelle est monté un couvercle 3 permettant de masquer dans la position assemblée représentée figure 1, les moyens d'application prévus dans le dispositif 1.The figure 1 represents a packaging and application device 1 according to the invention comprising a base 2 on which is mounted a cover 3 for masking in the assembled position shown figure 1 the application means provided in the device 1.

Selon ce mode de réalisation, l'ensemble comportant le dispositif 1 et le couvercle 3 définit un cylindre dont la génératrice correspond dans cet exemple à un axe de translation X du couvercle 3 relativement à l'embase 2, lors du montage de ce couvercle 3 sur le dispositif 1. Le couvercle 3 est alors circonscrit au maître couple de l'embase 2. En particulier, une section transversale à l'axe X de l'ensemble présente un contour convexe vers l'extérieur, par exemple de forme ovoïde. En particulier, la section transversale est elliptique de grand axe Y.According to this embodiment, the assembly comprising the device 1 and the lid 3 defines a cylinder whose generator in this example corresponds to a translation axis X of the lid 3 relative to the base 2, during assembly of the lid 3 on the device 1. The cover 3 is then circumscribed to the master torque of the base 2. In particular, a cross section to the X axis of the assembly has an outwardly convex contour, for example of ovoid shape. In particular, the cross section is elliptical with a large Y axis.

Le long de l'axe X, en position assemblée, l'embase 2 présente une hauteur H1, et le couvercle une hauteur H2. Le ratio de la hauteur H1 sur la somme des hauteurs H1 et H2, correspondant sensiblement à la hauteur de l'ensemble en position assemblée est comprise entre 0,3 et 0,4, et de préférence de l'ordre de 1/3. De préférence, la hauteur H1 correspond à l'épaisseur d'un pouce. En effet, l'embase est notamment configurée pour être attrapée en prise serrante entre deux doigts, par exemple entre le pouce et l'index. H1 est par exemple compris entre 1 et 3 centimètres, de préférence entre 1,5 et 2, cm.Along the axis X, in the assembled position, the base 2 has a height H1, and the lid a height H2. The ratio of the height H1 to the sum of the heights H1 and H2, corresponding substantially to the height of the assembly in the assembled position is between 0.3 and 0.4, and preferably of the order of 1/3. Preferably, the height H1 corresponds to the thickness of one inch. Indeed, the base is in particular configured to be gripped tightly between two fingers, for example between the thumb and the index finger. H1 is for example between 1 and 3 centimeters, preferably between 1.5 and 2 cm.

Pour permettre d'appliquer le produit contenu, l'utilisateur détache le couvercle 3 de l'embase 2, le dispositif 1 se présentant alors sous la forme présentée Figure 2.To enable the product contained to be applied, the user detaches the lid 3 from the base 2, the device 1 then being in the form presented Figure 2 .

Le couvercle 3 est par exemple retenu sur l'embase par des moyens d'encliquetage 4. Avantageusement, le couvercle 3 comporte également une lèvre annulaire 5 engagée en force dans un espace annulaire 6 défini par l'embase 2.The cover 3 is for example retained on the base by snap-fastening means 4. Advantageously, the cover 3 also comprises an annular lip 5 forcibly engaged in an annular space 6 defined by the base 2.

L'espace annulaire 6 est défini au niveau d'un chant 7 d'une paroi latérale 8 de l'embase 2. La paroi latérale 8 est dressée sur un fond 9 défini transversalement à l'axe X. Une première jupe annulaire externe 10 est dressée sur le chant 7, et présente un pourtour extérieur défini selon la génératrice du pourtour extérieur de la paroi latérale 8 cylindrique. L'espace annulaire 6 est défini entre cette première jupe annulaire externe 10 et une seconde jupe annulaire interne 11, s'étendant selon la génératrice du pourtour intérieur cylindrique de cette paroi latérale 8.The annular space 6 is defined at a edge 7 of a side wall 8 of the base 2. The side wall 8 is erected on a bottom 9 defined transversely to the axis X. A first outer annular skirt 10 is erected on the edge 7, and has an outer periphery defined according to the generator of the outer circumference of the cylindrical side wall 8. The annular space 6 is defined between this first outer annular skirt 10 and a second inner annular skirt 11, extending along the generatrix of the cylindrical inner periphery of this lateral wall 8.

Dans l'exemple, notamment visible de la figure 2, les moyens d'encliquetage 4 sont présentés sous la forme d'un bourrelet transversal 12 dépassant vers l'extérieur de l'embase 2, depuis la seconde jupe annulaire interne 11. A cet effet, la seconde jupe annulaire interne 11 présente une hauteur le long de l'axe X supérieure à celle de la jupe annulaire externe 10. Avantageusement, la jupe annulaire interne 11 présente deux bourrelets transversaux tels que 12, ces deux bourrelets s'étendent avantageusement sensiblement parallèlement au grand axe Y de l'ellipse formée par le pourtour extérieur de la jupe annulaire interne 11.In the example, especially visible from the figure 2 , the latching means 4 are in the form of a transverse bead 12 protruding outwardly from the base 2, from the second inner annular skirt 11. For this purpose, the second inner annular skirt 11 has a height along the axis X greater than that of the outer annular skirt 10. Advantageously, the inner annular skirt 11 has two transverse beads such as 12, these two beads advantageously extend substantially parallel to the major axis Y of the formed ellipse by the outer periphery of the inner annular skirt 11.

Ces moyens d'encliquetage 4 sont configurés pour coopérer avec un relief complémentaire prévu à l'intérieur du couvercle 3. L'immobilité axiale du couvercle 3 relativement à l'embase 2 est ainsi obtenue.These latching means 4 are configured to cooperate with a complementary relief provided inside the lid 3. The axial immobility of the lid 3 relative to the base 2 is thus obtained.

Pour assurer l'étanchéité de la fermeture, comme vu précédemment, la lèvre annulaire 5 est en prise serrante entre le pourtour intérieur de la première jupe annulaire externe 10 et un godron annulaire 13 prévu dépassant de la seconde jupe annulaire 11 dans l'espace annulaire 6.To seal the closure, as previously seen, the annular lip 5 is in tight engagement between the inner periphery of the first outer annular skirt 10 and an annular annular groove 13 provided protruding from the second annular skirt 11 in the annular space. . 6

Le couvercle 3 assemblé sur l'embase 2 permet ainsi de définir un volume intérieur étanche, une étanchéité statique étant prévue entre ces deux pièces. Le produit contenu dans l'ensemble est protégé vis-à-vis de l'environnement extérieur.The lid 3 assembled on the base 2 thus allows to define a sealed interior volume, a static seal being provided between these two parts. The product contained in the set is protected vis-à-vis the external environment.

Une cheminée 14 est dressée à l'intérieur de l'embase 2, la cheminée 14 étant rapportée à l'intérieur de cette dernière. Une telle cheminée 14 fait alors saillie relativement à ladite embase 2. Cette cheminée 14 définit un logement de produit, et comporte une ouverture de distribution 15 axialement opposée au fond 9.A chimney 14 is raised inside the base 2, the chimney 14 being attached inside the latter. Such a chimney 14 then protrudes relative to said base 2. This chimney 14 defines a product housing, and has a dispensing opening 15 axially opposite the bottom 9.

Figure 3, une section transversale interne de la cheminée 14 est en forme de « haricot ». En effet, cette section transversale interne comporte une portion concave 16 vers l'intérieur et une portion convexe 17 vers l'intérieur, Figure 3. Ces portions concave 16 et convexe 17 s'étendent selon un côté de plus grande dimension d'une section transversale du dispositif. Plus particulièrement, ces portions concave et convexe s'étendent généralement le long du grand axe Y, et notamment de part et d'autre de cet axe. L'ouverture de distribution 15 présente alors une section sensiblement identique à celle de la cheminée 14. De préférence, les portions 16 et 17 sont en vis-à-vis de telle sorte que l'ouverture de distribution forme une fente s'étendant selon une courbe C. Figure 3 , an internal cross section of the chimney 14 is shaped "bean". Indeed, this internal cross section has a concave portion 16 inwardly and a convex portion 17 inwardly, Figure 3 . These concave portions 16 and convex 17 extend along a larger dimension of a cross section of the device. More particularly, these concave and convex portions generally extend along the major axis Y, and in particular on either side of this axis. The dispensing opening 15 then has a section substantially identical to that of the chimney 14. Preferably, the portions 16 and 17 are vis-à-vis so that the dispensing opening forms a slot extending according to a curve C.

Les portions 16 et 17 présentent des rayons de courbure différents de telle sorte que la largeur de la fente mesurée perpendiculairement à la courbe C passe par un maximum dans une zone médiane, à distance des extrémités des portions 16 et 17. Dans l'exemple représenté, la portion concave vers l'intérieur 16 présente un rayon plus petit que la portion convexe vers l'intérieur 17, afin qu'aux extrémités, on ait un petit rayon qui permette de maquiller les cils du coin de l'oeil et qu'au centre on ait un largeur plus grande pour permettre le remplissage et obtenir un volume de produit important.The portions 16 and 17 have different radii of curvature so that the width of the slit measured perpendicular to the curve C passes through a maximum in a median zone, at a distance from the ends of the portions 16 and 17. In the example shown the inwardly concave portion 16 has a smaller radius than the convex portion 17, so that at the ends there is a small radius which makes it possible to make up the eyelashes of the corner of the eye and that in the center we have a wider width to allow filling and obtain a large volume of product.

La cheminée 14 est cylindrique de génératrice parallèle à l'axe X. Une paroi latérale 18 de cette cheminée présente une face externe présentant un profil convexe 19 vers l'extérieur et un profil concave 20 vers l'extérieur en correspondance des portions respectivement concave 16 et convexe 17. La paroi latérale 18 a dans cet exemple une épaisseur sensiblement constante. Le profil convexe vers l'extérieur 19, s'étend également sensiblement selon la courbe C. Il est mis au contact du pourtour intérieur de la jupe annulaire interne 11. De préférence, cette courbe C s'étend le long du grand axe Y de l'ellipse formée par la section transversale de l'embase 2. Il existe donc un espace 21 entre le profil concave vers l'extérieur 20 et le pourtour intérieur de la paroi latérale 8.The chimney 14 is cylindrical generatrix parallel to the axis X. A side wall 18 of this chimney has an outer face having a convex profile 19 outwardly and a concave profile 20 outwardly in correspondence of respectively concave portions 16 and convex 17. The side wall 18 has in this example a substantially constant thickness. The outwardly convex profile 19, also extends substantially along the curve C. It is brought into contact with the inner periphery of the inner annular skirt 11. Preferably, this curve C extends along the major axis Y of the ellipse formed by the cross section of the base 2. There is therefore a space 21 between the concave profile outwardly 20 and the inner periphery of the side wall 8.

Un moyen d'entraînement 22 est disposé en partie dans cet espace 21. Le moyen d'entraînement 22 comporte un bouton poussoir 23 logé dans l'espace 21 et coopérant avec un plateau disposé à l'intérieur de la cheminée 14, tel qu'un déplacement du bouton poussoir le long de l'axe X, permet une translation le long de cet axe du plateau dans la cheminée 14 en vue de la distribution de produit via l'orifice de distribution 15. Le bouton poussoir 23 est circonscrit au maître couple de l'embase 2, et même circonscrit au maître couple du godron annulaire 13.A drive means 22 is partially disposed in this space 21. The drive means 22 comprises a push button 23 housed in the space 21 and cooperating with a plate disposed inside the chimney 14, such as a displacement of the push button along the axis X, allows a translation along this axis of the plate in the chimney 14 for distribution of product through the dispensing orifice 15. The push button 23 is circumscribed to the master torque of the base 2, and even circumscribed to the master torque of the annular godron 13.

En variante, la portion concave vers l'intérieur 16 peut présenter un rayon de courbure identique, et donc superposable à celui de la portion convexe vers l'intérieur 17. En variante encore, représentée Figure 11, le rayon de courbure de la portion concave vers l'intérieur 16 peut être supérieur à celui de la portion convexe vers l'intérieur 17. En variante, Figure 12, le pourtour extérieur de l'embase 2 définit un demi cercle, à l'intérieur duquel est disposé la cheminée 14 délimitant le logement pour le produit P. le pourtour intérieur et extérieur de la cheminée 14 représente un demi anneau.As a variant, the concave interior portion 16 may have an identical radius of curvature, and therefore can be superimposed on that of the convex portion 17, Figure 11 the radius of curvature of the inwardly concave portion 16 may be greater than that of the inwardly convex portion 17. Alternatively, Figure 12 , the outer periphery of the base 2 defines a semicircle, inside which is disposed the chimney 14 defining the housing for the product P. the inner and outer periphery of the chimney 14 is a half-ring.

En variante, Figure 13, la cheminée 14 présente un profil intégralement concave vers l'intérieur, et est dressée dans une embase 2 présentant deux concavités vers l'extérieur, formant respectivement deux portions convexes 101 et 102 vers l'intérieur. Le moyen d'entraînement 22 est logé dans ce mode de réalisation, dans l'espace 21 défini entre le pourtour extérieur de la paroi latérale 18 et la concavité vers l'intérieur définie par la paroi 8 entre les deux portions convexes 101 et 102.In a variant, Figure 13 , the chimney 14 has an integrally concave profile towards the inside, and is erected in a base 2 having two concavities towards the outside, forming respectively two convex portions 101 and 102 inwards. The driving means 22 is housed in this embodiment, in the space 21 defined between the outer periphery of the side wall 18 and the inward concavity defined by the wall 8 between the two convex portions 101 and 102.

En variante, Figure 14, la cheminée 14 comporte deux portions convexes vers l'intérieur 111 et 112, et l'embase 2 présente une portion convexe 113 vers l'intérieur. La portion convexe 113 de l'embase 2 est disposée en regard de la portion convexe 111 de la cheminée 14, le moyen d'entraînement 22 étant disposé entre la deuxième portion convexe 112 de la cheminée 14 et l'embase 2.In a variant, Figure 14 , the chimney 14 has two inwardly convex portions 111 and 112, and the base 2 has a convex portion 113 inwardly. The convex portion 113 of the base 2 is disposed facing the convex portion 111 of the chimney 14, the drive means 22 being disposed between the second convex portion 112 of the chimney 14 and the base 2.

En variante de la figure 14, telle que représentée figure 15, la cheminée 14 comporte deux portions convexes vers l'intérieur 111 et 112 en regard de respectivement deux portions convexes 113 et 114 vers l'intérieur de l'embase 2. Un espace 21 est néanmoins ménagé entre la paroi 18 et l'embase 2 dans lequel l'encombrement du moyen d'entraînement 22 peut être placé.As a variant of the figure 14 as shown figure 15 , the chimney 14 has two inwardly convex portions 111 and 112 facing respectively two convex portions 113 and 114 towards the inside of the base 2. A space 21 is nevertheless provided between the wall 18 and the base 2 wherein the bulk of the drive means 22 can be placed.

Dans tous les modes de réalisation selon l'invention, la section transversale externe de l'embase n'est pas homothétique de la section transversale interne de la cheminée 14.In all the embodiments according to the invention, the external cross section of the base is not homothetic of the internal cross section of the chimney 14.

Le bouton poussoir 23 présente un contour et ou un effet de surface permettant d'en faciliter sa manipulation. En particulier, le bouton poussoir comporte un creux configuré pour coopérer avec la pulpe de l'extrémité du pouce.The push button 23 has a contour and or a surface effect to facilitate its handling. In particular, the push button has a hollow configured to cooperate with the pulp of the tip of the thumb.

La paroi latérale 18 comporte des rails de guidage 24 pour coopérer avec le bouton poussoir 23. Sur la figure 4, le bouton poussoir est dans une position médiane entre une bordure libre de la seconde jupe interne 11 et l'ouverture de distribution, le produit présenté ici sous la forme d'un pain solide est dressé en partie à l'extérieur de l'ouverture de distribution 15.The side wall 18 comprises guide rails 24 to cooperate with the push button 23. On the figure 4 , the push button is in a median position between a free edge of the second inner skirt 11 and the dispensing opening, the product presented here in the form of a solid cake is erected partly outside the opening of distribution 15.

Le bouton poussoir 23 est mobile relativement à la cheminée 14 entre une position basse et une position haute. Dans la position basse, une extrémité axiale libre du bouton poussoir, relativement à son axe de translation X, dépasse de l'embase 2 et est située à proximité de la bordure libre de la seconde jupe interne 11. En revanche, en position haute, l'extrémité axiale libre est disposée sensiblement dans le plan de l'ouverture de distribution 15, et plus particulièrement au niveau du chant libre 25 de la paroi latérale 18 de la cheminée 14.The push button 23 is movable relative to the chimney 14 between a low position and a high position. In the low position, a free axial end of the push button, relative to its translation axis X, protrudes from the base 2 and is located near the free edge of the second inner skirt 11. On the other hand, in the up position, the free axial end is disposed substantially in the plane of the dispensing opening 15, and more particularly at the free edge 25 of the side wall 18 of the chimney 14.

Des éléments de séparation / peignage tels qu'une rangée de dents effilées 26, de structure conique à base circulaire sont régulièrement répartis sur le chant libre 25. Ils sont sensiblement dressés parallèlement à l'axe X. Même en position haute, le bouton poussoir reste en deçà du plan dans lequel sont définies les extrémités libres des dents 26. Les dents 26 peuvent être coniques et présenter une base circulaire de diamètre de 0,8 mm, le diamètre au niveau de l'extrémité libre étant de l'ordre de 0,3 mm, et une hauteur est de l'ordre de 3 mm. Avantageusement les dents 26 sont espacées les unes des autres d'environ 1,4 mm.Separating / combing elements such as a row of tapered teeth 26, of conical structure with a circular base are evenly distributed over the free edge 25. They are substantially erect parallel to the axis X. Even in the up position, the push button remains below the plane in which the free ends of the teeth 26 are defined. The teeth 26 may be conical and have a circular base with a diameter of 0.8 mm, the diameter at the free end being of the order of 0.3 mm, and a height is of the order of 3 mm. Advantageously, the teeth 26 are spaced from each other by about 1.4 mm.

Le bouton poussoir 23 comporte une paroi formant écran 27 qui sort progressivement de l'embase, lorsqu'il est amené de la position basse vers la position haute. Cet écran 27 est initialement masqué dans l'embase 2 en position basse. Cet écran 27 comporte, comme cela est visible sur les vues éclatées des figures 5 et 6 un ergot 29 dressé transversalement à cet écran, au niveau d'une extrémité libre opposée à l'extrémité libre du bouton poussoir configuré pour être manipulée.The push button 23 has a screen wall 27 which gradually leaves the base when it is brought from the low position to the high position. This screen 27 is initially hidden in the base 2 in the low position. This screen 27 comprises, as can be seen in the exploded views of Figures 5 and 6 a lug 29 erected transversely to this screen, at a free end opposite the free end of the push button configured to be manipulated.

L'ergot est configuré pour traverser une rainure 28 formée dans une portion axiale 30 de la paroi latérale 18. En particulier, la rainure 28 est formée dans la face concave vers l'extérieur 20. La rainure 28 guide le coulissement du bouton poussoir le long de la cheminée 14.The lug is configured to pass through a groove 28 formed in an axial portion 30 of the side wall 18. In particular, the groove 28 is formed in the concave face towards the outside 20. The groove 28 guides the sliding of the push button on along the chimney 14.

Avantageusement la rainure 28 est formée dans la portion de la cheminée 14 contenue dans l'embase. Elle est masquée à la fois par l'embase et le bouton poussoir 23, en particulier l'écran 27 du bouton poussoir 23. La rainure 28 débouche au niveau d'une extrémité axiale opposée à celle définissant l'ouverture de distribution 15. Ainsi l'ergot 29 peut être inséré dans la rainure 28 par translation le long de la rainure 28.Advantageously, the groove 28 is formed in the portion of the chimney 14 contained in the base. It is masked both by the base and the push button 23, in particular the screen 27 of the push button 23. The groove 28 opens at an axial end opposite to that defining the dispensing opening 15. Thus the lug 29 can be inserted into the groove 28 by translation along the groove 28.

L'ergot 29 comporte une extrémité 31 engagée dans un orifice 32 formé dans une tige 33 dressée depuis un fond 34 du plateau 35 sur lequel le produit est disposé. La tige 34 est dressée dans une direction opposée à la direction de la position basse vers la position haute selon l'axe X. L'extrémité 31 peut être encliquetée, ou bien en montage serrant. Alternativement, étant donné, le confinement du bouton poussoir et du plateau relativement à la cheminée, l'engagement peut être souple, la seule mobilité tolérée étant axiale le long de l'axe X.The lug 29 has an end 31 engaged in an orifice 32 formed in a rod 33 raised from a bottom 34 of the plate 35 on which the product is disposed. The rod 34 is erected in a direction opposite to the direction from the low position to the high position along the X axis. The end 31 may be snapped or in a tight fit. Alternatively, given the confinement of the push button and the plate relative to the chimney, the engagement can be flexible, the only mobility tolerated being axial along the X axis.

La tige 33, à l'intérieur de la cheminée, est située dans la portion masquée par l'embase 2 lorsque le bouton poussoir 23 est en position basse. La rainure 28 forme en coopération avec le fond 9 une première butée B1 de translation du bouton poussoir relativement à la cheminée. La position basse est ainsi déterminée.The rod 33, inside the chimney, is located in the portion hidden by the base 2 when the push button 23 is in the lower position. The groove 28 forms in cooperation with the bottom 9 a first abutment B1 of translation of the push button relative to the chimney. The low position is thus determined.

Il est possible dans cette position basse de prévoir le plateau 35 en engagement étanche avec le pourtour intérieur de la cheminée 14. A cet effet, le pourtour extérieur du plateau présente un pourtour identique à la section transversale du pourtour intérieur de la paroi latérale 18. En revanche, il n'est de préférence pas prévu d'étanchéité dynamique entre le plateau et le pourtour intérieur de la cheminée lorsque le plateau est entraîné en translation à l'intérieur de la cheminée 14. En effet, le pourtour intérieur de la paroi latérale est légèrement évasé en direction de son ouverture de distribution 15.It is possible in this low position to provide the plate 35 in sealed engagement with the inner perimeter of the chimney 14. For this purpose, the outer periphery of the plate has a perimeter identical to the cross section of the inner periphery of the side wall 18. On the other hand, it is preferable not to provide dynamic sealing between the plate and the inner periphery of the chimney when the plate is driven in translation inside the chimney 14. Indeed, the inner periphery of the wall lateral is slightly flared towards its dispensing opening 15.

Le plateau 35 comporte une lèvre annulaire 36 pour délimiter le siège destiné à recevoir le produit à distribuer. Cette lèvre annulaire 36 peut venir en contact élastique étanche avec le pourtour intérieur de la paroi latérale, en particulier en position basse.The plate 35 has an annular lip 36 to define the seat for receiving the product to be dispensed. This annular lip 36 may come into sealed elastic contact with the inner periphery of the side wall, in particular in the lower position.

La rainure 28 comporte une deuxième butée B2 axialement opposée à la première butée B1, cette deuxième butée étant située en deçà du niveau de la lèvre annulaire 36 lorsque le bouton poussoir est en position basse. De ce fait la hauteur de produit H3 avant la première utilisation peut correspondre à la distance entre le plateau 35 en position basse et le plan du chant libre 25. Cette hauteur H3 est par exemple de l'ordre de 3 cm. La hauteur totale H4 entre le fond 9 de l'embase et le chant libre 25 de la cheminée 14 lorsque cette dernière est montée est sensiblement égale au double de la hauteur H3. Le ratio R de la hauteur H3 sur la hauteur H4 est de l'ordre de 0,5, comme cela est représenté sur les Figures 7 et 8.The groove 28 has a second stop B2 axially opposite the first stop B1, this second stop being located below the level of the annular lip 36 when the push button is in the lower position. As a result, the product height H3 before the first use can correspond to the distance between the plate 35 in the low position and the plane of the free edge 25. This height H3 is, for example, of the order of 3 cm. The total height H4 between the bottom 9 of the base and the free edge 25 of the chimney 14 when the latter is mounted is substantially equal to twice the height H3. The ratio R of the height H3 to the height H4 is of the order of 0.5, as represented on the Figures 7 and 8 .

En variante de réalisation du plateau 35 tel que représenté sur les Figures 1 à 6, où le fond 34 est plein, sur les Figures 7 à 9, le fond 34 est perméable au produit. Il comporte à cet effet de larges orifices 40. Ces orifices 40 sont notamment prévus pour permettre un remplissage en produit par le fond, l'embase 2 n'étant par disposée autour de la cheminée. Pour remplir les dispositifs selon le mode de réalisation des figures 7 et 8, la lèvre supérieure du plateau 35 étant serrée dans la cheminée 14, elle empêche le bouton poussoir de coulisser par gravité en direction de sa position haute. Il est également prévu un obturateur 41 agencé à l'intérieur de la cheminée pour boucher le logement et mettre en forme l'extrémité libre du produit coulé à chaud dans son logement. L'obturateur 41 présente un moyen de préhension dépassant dans le couvercle pour faciliter son retrait lors de la première utilisation.As an alternative embodiment of the plate 35 as shown in FIGS. Figures 1 to 6 , where the bottom 34 is full, on the Figures 7 to 9 the bottom 34 is permeable to the product. It comprises for this purpose large openings 40. These orifices 40 are in particular provided to allow a product filling by the bottom, the base 2 not being arranged around the chimney. To fill the devices according to the embodiment of Figures 7 and 8 , the upper lip of the plate 35 being clamped in the chimney 14, it prevents the push button from sliding by gravity towards its upper position. There is also a shutter 41 arranged inside the chimney to plug the housing and shape the free end of the hot cast product in its housing. The shutter 41 has a gripping means protruding into the cover to facilitate its removal during the first use.

La distance entre les deux butées B1 et B2, minorée de la hauteur axiale de l'ergot 29 au niveau de la rainure 28, définit la course axiale tolérée du plateau 35 dans la cheminée et correspond sensiblement à la distance entre la position basse et la position haute. Avantageusement, lorsque le bouton poussoir est dans la position haute, le plateau 35 se trouve sensiblement au niveau de l'ouverture de distribution 15.The distance between the two abutments B1 and B2, minus the axial height of the lug 29 at the groove 28, defines the permissible axial stroke of the plate 35 in the chimney and corresponds substantially to the distance between the low position and the high position. Advantageously, when the push button is in the high position, the plate 35 is substantially at the level of the dispensing opening 15.

En variante non représentée, un organe perméable au produit peut être disposé au niveau de l'ouverture de distribution 15. Cet organe perméable peut être poreux, fibreux, alvéolaire, ou encore percé de plusieurs canaux. Ainsi le débit et la distribution du produit au niveau de l'ouverture peuvent être modifiés. Une formule plus liquide peut ainsi être distribuée. Dans ce cas, le plateau est prévu pour être en contact étanche avec la cheminée 14 sur toute la hauteur entre la position basse et la position haute. Notamment, dans les cas où le dispositif est dépourvu de dents telles que 26, alors le dispositif 1 peut être utilisé pour l'application de rouge à lèvres ou de déodorant.Alternatively not shown, a product permeable member may be disposed at the dispensing opening 15. This permeable member may be porous, fibrous, alveolar or pierced with multiple channels. Thus the flow and the distribution of the product at the level of the opening can be modified. A more liquid formula can be distributed. In this case, the tray is intended to be in sealing contact with the chimney 14 over the entire height between the low position and the high position. In particular, in cases where the device is devoid of teeth such as 26, then the device 1 can be used for the application of lipstick or deodorant.

En variante non limitative de l'invention, le chant libre 25 peut ne pas comporter d'éléments de séparation/ peignage 26.As a non-limiting variant of the invention, the free edge 25 may not comprise separation / combing elements 26.

L'embase 2, le couvercle 3, la cheminée 14, le bouton poussoir 23 et le plateau 35 sont par exemple obtenus de moulage. Ils sont par exemple respectivement réalisés en Polyéthylène, polypropylène, polyamides, polyacétal, polystyrène. De préférence, le plateau 35 et la cheminée 14 ne seront pas réalisés dans un même matériau afin d'éviter les frottements entre deux pièces au même coefficient de frottement. Ainsi le déplacement du plateau 35 relativement à la cheminée 14 peut être fluide et sans provoquer un bruit de grincement.The base 2, the lid 3, the chimney 14, the push button 23 and the plate 35 are for example obtained from molding. They are for example respectively made of polyethylene, polypropylene, polyamides, polyacetal, polystyrene. Preferably, the plate 35 and the chimney 14 will not be made of the same material to avoid friction between two parts at the same coefficient of friction. Thus the displacement of the plate 35 relative to the chimney 14 can be fluid and without causing a squeaking noise.

Comme cela est représenté sur la Figure 10, le dispositif 1 selon l'invention est particulièrement configuré pour l'application d'un produit pâteux sur les cils. Ce dispositif est novateur pour les utilisatrices, ainsi que la gestuelle d'utilisation. En effet, l'utilisation d'un tel dispositif se fait préférentiellement en amenant le dispositif au contact de la base des cils, en présentant le grand axe Y sensiblement tangent à la cornée, le trajet que l'utilisatrice impose au dispositif pour obtenir l'enduction souhaitée de ses cils suit une boucle selon un mouvement dont les composantes sont définies dans un plan perpendiculaire à la cornée et parallèle à l'arête du nez. Le mouvement se décompose en trois temps, et correspond aux déplacements F1, F2 et F3 schématisés sur la Figure 10.As shown on the Figure 10 , the device 1 according to the invention is particularly configured for the application of a pasty product on the eyelashes. This device is innovative for users, as well as the gesture of use. Indeed, the use of such a device is preferably done by bringing the device into contact with the base of the eyelashes, having the major axis Y substantially tangential to the cornea, the path that the user imposes on the device to obtain the The desired coating of its eyelashes follows a loop in a movement whose components are defined in a plane perpendicular to the cornea and parallel to the bridge of the nose. The movement breaks down in three stages, and corresponds to the F1, F2 and F3 displacements schematized on the Figure 10 .

Selon cette gestuelle d'application, l'utilisatrice présente de préférence la courbe C définie par l'ouverture de distribution 15 sensiblement parallèle à la courbe formée par la bordure libre 100 de la paupière au niveau de laquelle les cils sont implantés.According to this application gesture, the user preferably has the curve C defined by the dispensing aperture 15 substantially parallel to the curve formed by the free edge 100 of the eyelid at which the eyelashes are implanted.

Avantageusement, les bords définis à la jonction entre les portions 16 et 17 respectivement permettent un traitement amélioré des bords d'une rangée de cils, notamment pour l'enduction des cils du bord interne et externe de l'oeil, y compris les retouches ponctuelles. Dans ce cas, les déplacements du dispositif sont toujours effectués dans le plan perpendiculaire à la cornée et parallèle à l'arête du nez, mais dans ce cas, le grand axe Y est disposé dans ce plan.Advantageously, the edges defined at the junction between the portions 16 and 17 respectively allow an improved treatment of the edges of a row of eyelashes, in particular for the coating of the eyelashes of the inner and outer edge of the eye, including spot retouches. . In this case, the movements of the device are always performed in the plane perpendicular to the cornea and parallel to the edge of the nose, but in this case, the major axis Y is disposed in this plane.

Dans toute la description, l'expression « comportant un » doit être considérée comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, the phrase "having one" should be considered synonymous with "having at least one", unless the opposite is specified.
