Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention est relative aux procédés et dispositifs de remplissage d'un contenant unitaire tel qu'un flacon ou un tube applicateur de produit cosmétique, notamment solide, à partir d'une capsule amovible, et aux capsules utilisables à cet effet.The present invention relates to methods and devices for filling a unit container such as a vial or an applicator tube of cosmetic product, in particular solid, from a removable capsule, and to the capsules that can be used for this purpose.

ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Les produits de maquillage ou de soin pour les lèvres sont le plus souvent conditionnés sous forme de flacons ou de tubes tels que ceux communément appelés « tubes de rouge à lèvres ».Lip makeup or care products are most often packaged in the form of bottles or tubes such as those commonly known as "lipstick tubes".

Les produits cosmétiques sont habituellement fabriqués industriellement en relativement grandes séries sur des machines de conditionnement qui présentent des cadences élevées.Cosmetic products are usually produced industrially in relatively large series on packaging machines which have high production rates.

Compte tenu du nombre d'unités à conditionner dans un laps de temps court, l'étape de remplissage des produits cosmétiques dans leur contenant final (flacons ou tubes) est optimisée de façon à pouvoir produire le plus grand nombre d'unités possible dans un court délai.Given the number of units to be packaged in a short period of time, the step of filling cosmetic products in their final container (bottles or tubes) is optimized so as to be able to produce the greatest number of units possible in a short delay.

De plus, la nature de ces produits conduit à mettre en place une succession d'étapes de chauffage et de refroidissement en cours de remplissage qui nécessitent l'utilisation d'un équipement adapté à une échelle de production industrielle.In addition, the nature of these products leads to setting up a succession of heating and cooling stages during filling which require the use of equipment adapted to an industrial production scale.

Du fait du nombre d'unités à produire et des contraintes techniques associées à la préparation et au conditionnement des produits cosmétiques, on ne peut donc offrir aux clientes, pour un même produit cosmétique, qu'un choix restreint de teintes ou de textures préalablement sélectionnées par le fabricant.Due to the number of units to be produced and the technical constraints associated with the preparation and packaging of cosmetic products, we can therefore offer customers, for the same cosmetic product, only a limited choice of shades or textures previously selected by the manufacturer.

D'autre part, les produits cosmétiques ont une durée de vie limitée après leur fabrication industrielle. En conséquence, les points de vente de produits de beauté ne conservent qu'un stock relativement limité de ces produits, ce qui limite encore plus les choix de teintes ou de textures proposées aux consommatrices.On the other hand, cosmetic products have a limited lifespan after their industrial manufacture. Consequently, the outlets of beauty products only keep a relatively limited stock of these products, which further limits the choice of shades or textures offered to consumers.

Enfin, pour une même gamme de produits, le contenant (tube, flacon) est identique quelles que soit la teinte et/ou la texture, ce qui interdit aux clientes de pouvoir personnaliser complètement leur produit cosmétique, en adaptant la teinte et/ou la texture retenues au contenant de leur choix.Finally, for the same range of products, the container (tube, bottle) is identical whatever the shade and / or texture, which prevents customers from being able to completely personalize their cosmetic product, by adapting the shade and / or the texture retained in the container of their choice.

Ceci est particulièrement vrai pour les rouges à lèvres, pour lesquels la cliente ne peut adapter la teinte et/ou la texture sur le mécanisme de son choix, ou encore pour les mascaras pour lesquels la brosse est vendue avec le produit conditionné.This is particularly true for lipsticks, for which the client cannot adapt the shade and / or texture to the mechanism of her choice, or for mascaras for which the brush is sold with the packaged product.

S'il veut élargir les possibilités de choix pour ses clientes, un fabricant n'a ainsi pas d'autres alternatives que de multiplier les grandes séries de produits, ce qui est économiquement risqué et coûteux.If it wants to widen the possibilities of choice for its customers, a manufacturer has no other alternative than to multiply the large series of products, which is economically risky and expensive.

Dans la description de l'invention qui suit, on entend par le terme générique de « rouge à lèvres » ou de « composition de rouge à lèvres » ou « tube de rouge à lèvres », un produit solide adapté au maquillage et/ou au soin des lèvres, sans limitation de teinte ou de texture, pouvant être conformé de manière stable dans le temps et à une température ambiante sous forme de bâton ou de stick.In the description of the invention which follows, the generic term is understood to mean “lipstick” or “lipstick composition” or “lipstick tube”, a solid product suitable for making up and / or lip care, without limitation in shade or texture, which can be shaped stably over time and at room temperature in the form of a stick or stick.

On entend par « produit solide » un produit susceptible d'être pénétré par un objet rigide sans pour autant perdre son intégrité lorsqu'il est conformé sous une forme donnée, telle qu'un bâton.“Solid product” is understood to mean a product capable of being penetrated by a rigid object without losing its integrity when it is shaped in a given form, such as a stick.

Par ailleurs, il est connu du brevet US 5,316,712 un procédé de fabrication de rouge à lèvres consistant à chauffer une composition visqueuse dans un vérin chauffant, à expulser la composition visqueuse au moyen du vérin pour mouler la composition chauffée dans des moules.Furthermore, it is known from the patent US 5,316,712 a method of manufacturing lipstick comprising heating a viscous composition in a heating cylinder, expelling the viscous composition by means of the cylinder to mold the heated composition in molds.

OBJETS ET RESUME DE L'INVENTIONOBJECTS AND SUMMARY OF THE INVENTION

La présente invention a notamment pour but de palier tout ou partie des inconvénients susmentionnés.The object of the present invention is in particular to overcome all or part of the aforementioned drawbacks.

L'invention propose un procédé de remplissage d'un contenant unitaire de produit cosmétique par un produit cosmétique, à partir d'une capsule contenant une dose dudit produit cosmétique, la capsule étant remplie de produit cosmétique sous forme solide, le produit cosmétique étant une composition de rouge à lèvres, la capsule comportant une dose de composition de rouge à lèvres permettant la préparation d'un unique bâton de rouge à lèvres, ladite capsule comportant un tube rempli de ladite dose de produit cosmétique, ledit tube s'étendant entre une première extrémité obturée par un piston monté coulissant dans le tube et une deuxième extrémité formant une buse de sortie initialement fermée, ledit procédé comportant au moins les étapes suivantes :

  • une étape d'ouverture de la buse de sortie de la capsule,
  • une étape de coulage dans laquelle on coule ledit produit cosmétique dans contenant en actionnant le piston de la capsule pour expulser ledit produit cosmétique par la buse de sortie,
  • et une étape suivant laquelle on peut fluidifier le produit cosmétique dans la capsule par chauffage,
The invention provides a method of filling a container. unit of cosmetic product by a cosmetic product, from a capsule containing a dose of said cosmetic product, the capsule being filled with cosmetic product in solid form, the cosmetic product being a lipstick composition, the capsule comprising a dose of lipstick composition allowing the preparation of a single stick of lipstick, said capsule comprising a tube filled with said dose of cosmetic product, said tube extending between a first end closed by a piston mounted to slide in the tube and a second end forming an initially closed outlet nozzle, said method comprising at least the following steps:
  • a step of opening the capsule outlet nozzle,
  • a pouring step in which said cosmetic product is poured into a container by actuating the piston of the capsule to expel said cosmetic product through the outlet nozzle,
  • and a step according to which the cosmetic product can be made more fluid in the capsule by heating,

Grâce à ces dispositions, le procédé conforme à l'invention permet de conditionner de façon unitaire des produits cosmétiques, par exemple des tubes de rouge à lèvres, personnalisés et à la demande, dans lequel le choix de la teinte et/ou de la texture de la composition de rouge à lèvres ainsi que le contenant lui-même parmi un certain nombre de références, peut être laissé à la cliente. Le procédé permet à la consommatrice de personnaliser complètement son propre produit fini constitué d'un rouge à lèvres conditionné dans un contenant.Thanks to these provisions, the method according to the invention makes it possible to package cosmetic products, for example lipstick tubes, personalized and on demand, in which the choice of shade and / or texture of the composition of lipstick as well as the container itself among a number of references, can be left to the client. The process allows consumers to completely personalize their own finished product consisting of a lipstick packaged in a container.

Le procédé de l'invention permet la fabrication de produits finis conditionnés sur le point de vente, devant la consommatrice immédiatement après que celle-ci ait fait son choix pour le produit cosmétique d'une part et pour le contenant d'autre part.The method of the invention allows the production of finished products packaged at the point of sale, in front of the consumer immediately after she has made her choice for the cosmetic product on the one hand and for the container on the other hand.

Selon une mise en oeuvre particulière, qui sera décrite par la suite dans le cadre d'un mode de réalisation, l'invention peut concerner par exemple un procédé de remplissage d'un tube applicateur de produit cosmétique solide tel qu'un rouge à lèvres à partir d'une capsule contenant une dose dudit produit, procédé dans lequel, on peut dans un premier temps fluidifier ledit produit cosmétique dans la capsule par chauffage avant d'ouvrtir la buse de sortie de la capsule.According to a particular implementation, which will be described later in the context of an embodiment, the invention may relate, for example, to a method of filling an applicator tube with a solid cosmetic product such as a lipstick. from a capsule containing a dose of said product, process in which, it is possible at first to thin said product cosmetic in the capsule by heating before opening the capsule outlet nozzle.

Grâce à ces dispositions, le procédé conforme à l'invention permet de créer de façon unitaire des tubes applicateurs de produit cosmétique solide, par exemple des tubes de rouge à lèvres, personnalisés et à la demande.Thanks to these provisions, the method according to the invention makes it possible to create unitary applicator tubes for solid cosmetic product, for example lipstick tubes, personalized and on demand.

Par ailleurs, le fait de disposer de produits cosmétiques contenus dans des capsules unitaires fermées hermétiquement présente l'avantage complémentaire de pouvoir conserver les produits cosmétiques plus longtemps.In addition, the fact of having cosmetic products contained in hermetically closed unit capsules has the additional advantage of being able to keep cosmetic products longer.

Dans divers modes de mise en oeuvre du procédé selon l'invention, il peut éventuellement comprendre également les étapes suivantes, prises séparément ou en combinaison :

  • le chauffage du produit cosmétique dans la capsule peut être réalisé à une température comprise sensiblement entre 80 et 100 °C, la température pouvant être, de préférence, sensiblement de 90°C ;
  • le chauffage peut également être réalisé de façon optionnelle dans le cas où l'on cherche à fluidifier légèrement un produit pâteux ou semi-solide, de façon à faciliter l'expulsion du produit cosmétique hors de la capsule.
  • le chauffage peut être réalisé pendant un temps compris sensiblement entre une et cinq minutes, de préférence environ quatre minutes ;
  • l'étape d'ouverture de ladite buse de sortie de ladite capsule peut être réalisée par section d'une tête sécable que comporte ladite capsule ;
  • le procédé peut comporter, en outre, après ladite étape de coulage, une étape de refroidissement dans laquelle le produit cosmétique est solidifié dans le contenant unitaire ;
  • l'étape de refroidissement peut être réalisée par soufflage d'air ; et
  • l'étape de refroidissement peut être réalisée pendant une durée comprise entre sensiblement une minute et cinq minutes, et de préférence une durée d'environ quatre minutes.
In various embodiments of the method according to the invention, it can optionally also include the following steps, taken separately or in combination:
  • the heating of the cosmetic product in the capsule can be carried out at a temperature of substantially between 80 and 100 ° C, the temperature possibly being preferably of 90 ° C;
  • heating can also be carried out optionally in the case where it is sought to slightly thin a pasty or semi-solid product, so as to facilitate the expulsion of the cosmetic product from the capsule.
  • the heating can be carried out for a time substantially between one and five minutes, preferably about four minutes;
  • the step of opening said outlet nozzle of said capsule can be carried out by section of a breakable head that comprises said capsule;
  • the method can also comprise, after said casting step, a cooling step in which the cosmetic product is solidified in the unit container;
  • the cooling step can be carried out by blowing air; and
  • the cooling step can be carried out for a period of between substantially one minute and five minutes, and preferably a period of approximately four minutes.

L'étape de refroidissement est particulièrement utile dans le cas où l'on met en oeuvre le procédé pour remplir un tube applicateur de produit cosmétique solide préalablement fluidifié par chauffage au cours de l'étape préparatoire. Le refroidissement permet d'accélérer le retour du produit cosmétique à l'état solide initial, sa mise en forme, et la mise à disposition du produit à la cliente.The cooling step is particularly useful in the case where the method is used to fill an applicator tube with a solid cosmetic product previously fluidized by heating during the step. preparatory. The cooling accelerates the return of the cosmetic product to the initial solid state, its shaping, and the provision of the product to the client.

Par ailleurs, l'invention a également pour objet une capsule comportant un tube s'étendant entre une première extrémité obturée par un piston monté coulissant dans le tube et une deuxième extrémité formant une buse de sortie qui est fermée, ledit tube étant rempli d'un produit cosmétique, le produit étant sous forme solide, le produit cosmétique étant une composition de rouge à lèvres.Furthermore, the invention also relates to a capsule comprising a tube extending between a first end closed by a piston mounted sliding in the tube and a second end forming an outlet nozzle which is closed, said tube being filled with a cosmetic product, the product being in solid form, the cosmetic product being a lipstick composition.

Comme expliqué précédemment, une telle capsule présente l'avantage de permettre une meilleure conservation du produit (par exemple, pour le raisin de rouge à lèvres) que celle d'un dispositif applicateur classique après conditionnement.As explained above, such a capsule has the advantage of allowing better preservation of the product (for example, for the lipstick grape) than that of a conventional applicator device after packaging.

La présence d'un piston obturant l'une des extrémités de la capsule permet, tout au long du procédé de l'invention, d'éviter le contact entre le produit cosmétique contenu dans la capsule avec une quelconque partie non amovible d'un dispositif de remplissage conforme à l'invention qui sera défini plus loin. Tel n'est pas le cas dans les dispositifs de remplissage usuels qui réalisent des remplissages de récipients en grandes séries.The presence of a piston closing one of the ends of the capsule makes it possible, throughout the process of the invention, to avoid contact between the cosmetic product contained in the capsule with any non-removable part of a device filling according to the invention which will be defined later. This is not the case in the usual filling devices which carry out filling of containers in large series.

Dans divers modes de réalisation de la capsule selon l'invention, on peut éventuellement avoir recours de manière avantageuse à l'une et/ou à l'autre des dispositions suivantes :

  • la buse de sortie de la capsule peut être fermée hermétiquement par une tête sécable ;
  • un capuchon rigide peut être placé contre le piston de la capsule ;
  • le tube de la capsule peut être réalisé dans un matériau solide ayant une température de fusion supérieure à 100 °C ;
  • le tube peut être réalisé en matériau transparent ;
  • le piston de la capsule peut également être réalisé en matériau transparent.
In various embodiments of the capsule according to the invention, one can optionally have recourse to one and / or the other of the following arrangements:
  • the capsule outlet nozzle can be hermetically closed by a breakable head;
  • a rigid cap can be placed against the piston of the capsule;
  • the capsule tube can be made of a solid material having a melting temperature above 100 ° C;
  • the tube can be made of transparent material;
  • the piston of the capsule can also be made of transparent material.

L'utilisation d'un tel matériau transparent pour le tube rend ainsi visible la teinte du produit cosmétique qu'il contient avant la mise en œuvre du procédé de l'invention.The use of such a transparent material for the tube thus makes the shade of the cosmetic product that it contains visible before the implementation of the method of the invention.

Le remplissage de la capsule amovible peut être réalisé par coulage à chaud dudit produit cosmétique par l'extrémité non sécable de ladite capsule puis fermeture par insertion du piston.The removable capsule can be filled by hot pouring said cosmetic product through the non-breakable end of said capsule and then closing by insertion of the piston.

Après utilisation pour la fabrication de produit cosmétique conditionné dans un contenant unitaire, la capsule peut être récupérée par un opérateur(trice) et recyclée.After use for the manufacture of cosmetic product packaged in a unit container, the capsule can be recovered by an operator and recycled.

La capsule peut être réalisée dans tout type de matériau rigide compatible avec le produit cosmétique qu'elle contient, et compatible avec les conditions de mise en œuvre du procédé (chauffage refroidissement, sécabilité).The capsule can be made of any type of rigid material compatible with the cosmetic product it contains, and compatible with the conditions for implementing the process (heating, cooling, breakability).

Le matériau peut être avantageusement un verre blanc, coloré ou teinté ou bien encore comprendre un habillage extérieur décoratif ou une impression indicative (marque, référence etc.), un polymère thermoplastique (polyéthylène, polytéréphtalate d'éthylène ou polyoxyméthylène) ou toute autre matière qui ne se déforme pas sous l'effet d'une augmentation de chaleur.The material can advantageously be a white, colored or tinted glass or else comprise a decorative exterior covering or an indicative impression (brand, reference etc.), a thermoplastic polymer (polyethylene, polyethylene terephthalate or polyoxymethylene) or any other material which does not deform under the effect of an increase in heat.

Le tube de la capsule est avantageusement de forme cylindrique.The capsule tube is advantageously cylindrical in shape.

La forme du piston est adaptée de façon à coulisser sans entrave le long des parois dudit tube, et à expulser la totalité du produit cosmétique, hors volume mort, hors de la capsule.The shape of the piston is adapted so as to slide without obstacle along the walls of said tube, and to expel the entire cosmetic product, excluding dead volume, out of the capsule.

L'invention a enfin pour objet un dispositif de remplissage d'un contenant unitaire par un produit cosmétique, à partir d'une capsule telle que définie ci-dessus, la capsule comportant une dose de composition de rouge à lèvres permettant la préparation d'un unique bâton de rouge à lèvres, ladite capsule étant amovible dans ledit dispositif, ledit dispositif comportant :

  • des moyens d'ouverture, aptes à ouvrir la buse de sortie de ladite capsule,
  • et des moyens de coulage dudit produit cosmétique, aptes à couler ledit produit cosmétique fluidifié dans le contenant unitaire en actionnant le piston de la capsule pour expulser ledit produit cosmétique par ladite buse de sortie.
The invention finally relates to a device for filling a unit container with a cosmetic product, from a capsule as defined above, the capsule comprising a dose of lipstick composition allowing the preparation of a single stick of lipstick, said capsule being removable in said device, said device comprising:
  • opening means, capable of opening the outlet nozzle of said capsule,
  • and means for pouring said cosmetic product, capable of pouring said fluidized cosmetic product into the unit container by actuating the piston of the capsule to expel said cosmetic product through said outlet nozzle.

Selon une mise en œuvre particulière préférée, l'invention a pour objet un dispositif de remplissage d'un contenant unitaire de produit cosmétique, d'une utilisation simple, facilement utilisable par un(e) opérateur(rice) ayant été formé au préalable, ne nécessitant aucune maintenance particulière et notamment aucun nettoyage entre deux mise en œuvre du fait de l'utilisation de capsules amovibles, et peu encombrant. Ces avantages rendent possible l'installation dudit dispositif sur un point de vente pour la fabrication de produits cosmétiques personnalisés selon les choix des consommatrices, par exemple un tube de rouge à lèvres dont la teinte, la texture, voire également le tube applicateur peuvent être sélectionnés par la consommatrice elle-même,According to a particular preferred implementation, the invention has for subject a device for filling a unit container of cosmetic product, of simple use, easily usable by an operator having been trained beforehand, requiring no particular maintenance and in particular no cleaning between two work due to the use of removable capsules, and compact. These advantages make it possible to install said device at a point of sale for the manufacture of personalized cosmetic products according to the choices of consumers, for example a tube of lipstick whose shade, texture, or even also the applicator tube can be selected. by the consumer herself,

La présente invention vise plus particulièrement un dispositif de remplissage d'un contenant unitaire de produit cosmétique, notamment solide, comme par exemple un tube de rouge à lèvres, grâce à l'utilisation d'une capsule amovible contenant une dose dudit produit cosmétique.The present invention relates more particularly to a device for filling a unit container of cosmetic product, in particular solid, such as for example a tube of lipstick, through the use of a removable capsule containing a dose of said cosmetic product.

Le produit cosmétique peut être toute composition cosmétique conditionnée en flacon ou en tube.The cosmetic product can be any cosmetic composition packaged in a bottle or a tube.

Le produit cosmétique peut être destiné au soin, et/ou au maquillage des lèvres.The cosmetic product can be intended for the care and / or for making up the lips.

Le produit cosmétique peut être par exemple un rouge à lèvres.The cosmetic product can for example be a lipstick.

La texture du produit cosmétique, et notamment sa viscosité est adaptée de façon à pouvoir d'une part être conditionnée dans une capsule telle que décrite précédemment, ensuite d'être expulsée de la capsule par action du piston du dispositif de remplissage, et enfin de pouvoir être utilisée de façon confortable par l'utilisatrice et produire le résultat attendu en terme d'effet de maquillage, de longévité de tenue après application, ou d'efficacité du soin.The texture of the cosmetic product, and in particular its viscosity, is adapted so as to be able on the one hand to be packaged in a capsule as described above, then to be expelled from the capsule by action of the piston of the filling device, and finally to be able to be used comfortably by the user and produce the expected result in terms of makeup effect, longevity of hold after application, or effectiveness of the treatment.

Ainsi le produit de maquillage est avantageusement sous forme solide.Thus the makeup product is advantageously in solid form.

La texture est notamment adaptée de façon à ne pas s'écouler librement par gravité hors de la capsule après que cette dernière ait été ouverte.The texture is especially adapted so as not to flow freely by gravity out of the capsule after the latter has been opened.

Dans le cas où le produit cosmétique est sous forme solide, on utilise un élément de chauffage et des moyens de refroidissement de façon à expulser le produit de la capsule dans lequel il est conditionné vers le contenant dans lequel il sera refroidi pour durcir et retrouver sa texture initiale.In the case where the cosmetic product is in solid form, a heating element and cooling means are used so as to expel the product from the capsule in which it is packaged to the container in which it will be cooled to harden and regain its initial texture.

Dans le cas de textures pâteuses ou semi-solides, il est possible de chauffer le produit en adaptant la température et/ou le temps de chauffage, de façon à faciliter l'expulsion du produit cosmétique hors de la capsule et/ou de le refroidir de façon à rétablir sa texture finale rapidement après remplissage dans le contenant.In the case of pasty or semi-solid textures, it is possible to heat the product by adjusting the temperature and / or the heating time, so as to facilitate the expulsion of the cosmetic product from the capsule and / or to cool it so as to restore its final texture quickly after filling in the container.

La texture peut être adaptée par l'utilisation d'excipients gélifiants, épaississants tels que par exemple des polymères naturels ou synthétiques qui permettent d'obtenir cet effet dans des phases hydrophiles ou lipophiles, ou encore des cires.The texture can be adapted by the use of gelling excipients, thickeners such as for example natural or synthetic polymers which make it possible to obtain this effect in hydrophilic or lipophilic phases, or also in waxes.

Les produits cosmétiques peuvent en outre comprendre des conservateurs des agents antioxydants, des filtres UV, des charges pulvérulentes telles que des pigments colorés, des nacres ou des poudres synthétiques améliorant le confort d'application du produit cosmétique sur la peau ou les lèvres.Cosmetic products can also include preservatives, antioxidant agents, UV filters, powdery fillers such as colored pigments, pearlescent agents or synthetic powders improving the comfort of application of the cosmetic product on the skin or the lips.

Classiquement, un produit solide du type de ceux qu'on prépare à l'aide du procédé de l'invention est constitué d'une base, avantageusement anhydre pouvant comprendre une cire ou un mélange de cires, des huiles, des polymères texturant de phases grasses. La base peut être opaque, par exemple en présence de cire ou bien être translucide ou transparente de façon à faire ressortir la teinte des pigments qui y sont dispersés.Conventionally, a solid product of the type of those which are prepared using the process of the invention consists of a base, advantageously anhydrous, which can comprise a wax or a mixture of waxes, oils, texturing polymers of fatty phases. The base can be opaque, for example in the presence of wax or else be translucent or transparent so as to bring out the color of the pigments which are dispersed therein.

Le produit cosmétique de maquillage ou de soin est déposé par contact sur une surface telle que la peau du visage, la surface des lèvres, le contour des yeux ou les cils.The cosmetic make-up or care product is deposited by contact on a surface such as the skin of the face, the surface of the lips, the contour of the eyes or the eyelashes.

Le contenant, également dénommé conditionnement unitaire ou unité de conditionnement dans la description peut être tout type de conditionnement adapté au produit cosmétique qu'il contient et/ou son utilisation par la consommatrice.The container, also called unit packaging or packaging unit in the description, can be any type of packaging suitable for the cosmetic product it contains and / or its use by the consumer.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the different figures, the same references designate identical or similar elements.

Les figures qui vont être décrites montrent un dispositif de remplissage d'un tube applicateur de rouge à lèvres, c'est-à-dire un dispositif qui permet de remplir un seul tube applicateur à la fois, et ce à la demande d'une cliente.The figures which will be described show a device for filling an applicator tube with lipstick, that is to say a device which makes it possible to fill only one applicator tube at a time, and this at the request of a client.

Il devra être entendu que, même si l'exemple décrit concerne un tube de rouge à lèvres, l'invention s'applique à n'importe contenant unitaire de produit cosmétique.It should be understood that, even if the example described relates to a lipstick tube, the invention applies to any unit container of cosmetic product.

Le dispositif décrit ci-dessous est une mise en œuvre particulière de l'invention en ce qu'il permet de préparer un tube applicateur unitaire contenant un produit cosmétique solide. Le dispositif décrit ici contient notamment un élément de chauffage de la capsule et des moyens de refroidissement du tube applicateur.The device described below is a particular implementation of the invention in that it makes it possible to prepare a unitary applicator tube containing a solid cosmetic product. The device described here contains in particular a heating element for the capsule and means for cooling the applicator tube.

L'homme du métier est à même d'adapter le dispositif décrit ci-dessous pour le rendre utilisable d'une part pour des compositions pâteuses ou semi-solides ne nécessitant pas de moyens de chauffage et/ou de refroidissement et d'autre part pour le remplissage de flacons avec des produits cosmétiques de texture solide, pâteuse ou semi-solide.A person skilled in the art is able to adapt the device described below to make it usable on the one hand for pasty or semi-solid compositions not requiring heating and / or cooling means and on the other hand for filling bottles with cosmetic products with a solid, pasty or semi-solid texture.

Le dispositif qui va être décrit permet de remplir un mécanisme de tube applicateur de rouge à lèvres à partir d'une capsule contenant une composition de rouge à lèvres (produit cosmétique) de la couleur et de la texture choisies par une cliente.The device which will be described makes it possible to fill a mechanism with a lipstick applicator tube from a capsule containing a composition of lipstick (cosmetic product) of the color and texture chosen by a client.

Grâce au dispositif permettant le remplissage d'un mécanisme de tube applicateur de rouge à lèvres, il est également possible pour la cliente de choisir le tube applicateur lui-même dans lequel sera monté ledit mécanisme.Thanks to the device allowing the filling of a lipstick applicator tube mechanism, it is also possible for the client to choose the applicator tube itself in which said mechanism will be mounted.

Ainsi, l'invention permet de créer un tube de rouge à lèvres à la demande et entièrement personnalisé.Thus, the invention makes it possible to create a tube of lipstick on demand and entirely personalized.

La figure 1 montre une capsule 1 utilisable dans le dispositif de remplissage qui sera décrit dans un second temps.The figure 1 shows a capsule 1 usable in the filling device which will be described in a second step.

La capsule 1 est de forme générale tubulaire, et comporte un tube 2 de forme cylindrique, dénommé indifféremment « cylindre » dans la description qui suit, s'étendant entre une première extrémité 3 et une seconde extrémité 4.The capsule 1 is of generally tubular shape, and comprises a tube 2 of cylindrical shape, denominated indifferently “cylinder” in the description which follows, extending between a first end 3 and a second end 4.

Le cylindre 2 de la capsule 1 peut être réalisé en verre, en polymère thermoplastique (polyéthylène, polytéréphtalate d'éthylène ou polyoxyméthylène) ou en toute autre matière qui ne se déforme pas sous l'effet d'une augmentation de chaleur. En effet, et comme il sera vu par la suite, le procédé de remplissage conforme à l'invention nécessite de chauffer la capsule afin de fluidifier son contenu (rouge à lèvres 10, ou toute autre composition pour le soin et/ou le maquillage), pour permettre le remplissage du mécanisme.The cylinder 2 of the capsule 1 can be made of glass, of a thermoplastic polymer (polyethylene, polyethylene terephthalate or polyoxymethylene) or any other material which does not deform under the effect of an increase in heat. Indeed, and as will be seen later, the filling process according to the invention requires heating the capsule in order to fluidize its content (lipstick 10, or any other composition for care and / or makeup) , to allow filling of the mechanism.

Notamment, le cylindre 2 de la capsule est réalisé dans un matériau solide tel que l'un ou l'autre cité ci-dessus, par exemple, qui résiste à une température supérieure à 100°C.In particular, the cylinder 2 of the capsule is made of a solid material such as one or the other mentioned above, for example, which withstands a temperature above 100 ° C.

Par ailleurs le matériau utilisé est inerte vis-à-vis de la composition de rouge à lèvres qu'il contient.Furthermore, the material used is inert with respect to the composition of lipstick that it contains.

Le cylindre 2 est, par ailleurs, avantageusement réalisé dans un matériau transparent, de sorte que la cliente puisse observer distinctement la teinte de la composition de rouge à lèvres 10 contenu dans la capsule.The cylinder 2 is moreover advantageously made of a transparent material, so that the client can clearly observe the shade of the lipstick composition 10 contained in the capsule.

On comprendra par matériau transparent tout matériau non teinté laissant apercevoir distinctement la forme et la couleur du produit contenu dans la capsule par transparence.Transparent material will be understood to mean any untinted material allowing the shape and color of the product contained in the capsule to be seen clearly by transparency.

La première extrémité 3 du cylindre 2 de la capsule 1 présente un épaulement 5 qui permettra de retirer facilement la capsule 1 d'un logement du dispositif de remplissage (voir par la suite).The first end 3 of the cylinder 2 of the capsule 1 has a shoulder 5 which will allow the capsule 1 to be easily removed from a housing of the filling device (see below).

La capsule 1 pourrait présenter, sans sortir du cadre de l'invention, tout autre moyen qui permettrait de réaliser la même fonction, comme par exemple une collerette extérieure.The capsule 1 could present, without departing from the scope of the invention, any other means which would make it possible to perform the same function, such as for example an external collar.

Conformément à l'invention, la première extrémité 3 du cylindre 2 de la capsule 1 est obturée par un piston 6 qui est monté coulissant dans le cylindre 2.According to the invention, the first end 3 of the cylinder 2 of the capsule 1 is closed by a piston 6 which is slidably mounted in the cylinder 2.

Le piston 6 ferme hermétiquement la capsule 1, à la façon d'un bouchon. Il peut servir de support publicitaire et être revêtu, pour des questions d'esthétisme, d'un film métallique visible à travers la paroi du cylindre.The piston 6 hermetically closes the capsule 1, like a stopper. It can serve as an advertising medium and be coated, for aesthetic reasons, with a metallic film visible through the wall of the cylinder.

Le piston 6 peut être réalisé en matériau transparent de sorte que la couleur du rouge à lèvres 10 contenu dans la capsule 1 peut également être visible à travers le piston 6.The piston 6 can be made of transparent material so that the color of the lipstick 10 contained in the capsule 1 can also be seen through the piston 6.

Le matériau constituant le piston est inerte vis-à-vis de la composition de rouge à lèvre contenue dans le cylindre.The material constituting the piston is inert with respect to the lipstick composition contained in the cylinder.

Par ailleurs, dans le cadre du mode de réalisation de la capsule représentée, le piston 6 peut être recouvert d'un capuchon 7 réalisé en matière rigide, qui assure un meilleur appui d'une tige sur le piston pour permettre son déplacement dans le cylindre 2. Pour également centrer la tige de déplacement du piston, le capuchon 7 peut également comprendre une empreinte 8 correspondant à l'extrémité de la tige de façon à centrer cette dernière dans l'axe du cylindre 2.Furthermore, in the context of the embodiment of the capsule shown, the piston 6 can be covered with a cap 7 made of rigid material, which ensures better support of a rod on the piston to allow its movement in the cylinder 2. To also center the piston displacement rod, the cap 7 can also include an imprint 8 corresponding to the end of the rod so as to center the latter in the axis of the cylinder 2.

Le capuchon 7 peut également être réalisé en matériau transparent.The cap 7 can also be made of transparent material.

La seconde extrémité 4 du cylindre 2 de la capsule 1 forme une buse 9 de sortie de la capsule, qui est fermée initialement par une tête sécable 11.The second end 4 of the cylinder 2 of the capsule 1 forms a nozzle 9 for leaving the capsule, which is closed initially by a breakable head 11.

La tête sécable 11 présente une rainure périphérique 12 qui permet de guider des moyens assurant la section de la tête dans le dispositif de remplissage qui sera décrit pas la suite, facilitant ainsi la section de la tête sécable 11.The breakable head 11 has a peripheral groove 12 which makes it possible to guide means ensuring the section of the head in the filling device which will be described below, thus facilitating the section of the breakable head 11.

Il devra être noté que la seconde extrémité pourrait être revêtue d'une couche métallique à des fins esthétiques.It should be noted that the second end could be coated with a metallic layer for aesthetic purposes.

Sur la figure 1, la capsule 1 est remplie d'une composition de rouge à lèvres 10 sous forme solide.On the figure 1 , the capsule 1 is filled with a lipstick composition 10 in solid form.

La capsule 1 comprend une quantité de la composition de rouge à lèvres permettant la préparation d'un unique bâton de rouge à lèvre.Capsule 1 includes an amount of the lipstick composition allowing the preparation of a single lipstick stick.

La quantité peut éventuellement être légèrement supérieure à celle nécessaire, de façon à tenir compte d'un volume mort dans la capsule au moment de la préparation du bâton de rouge à lèvres.The quantity may possibly be slightly greater than that necessary, so as to take account of a dead volume in the capsule at the time of the preparation of the lipstick stick.

La figure 2 montre, quant à elle, un contenant unitaire constitué par un mécanisme 13 de tube applicateur de rouge à lèvres apte à être rempli grâce au dispositif de remplissage qui sera décrit par la suite.The figure 2 shows, for its part, a unitary container constituted by a mechanism 13 of lipstick applicator tube capable of being filled by means of the filling device which will be described later.

Le mécanisme 13 comporte un tube protecteur 14 qui s'étend entre une première 15 et une seconde 16 extrémité, le tube protecteur présentant une forme générale cylindrique de révolution d'axe central X.The mechanism 13 comprises a protective tube 14 which extends between a first 15 and a second 16 end, the protective tube having a generally cylindrical shape of revolution with a central axis X.

La seconde extrémité 16 est fermée par un opercule 17 thermo scellé, par exemple. L'opercule 17 peut également être emboîté dans la seconde extrémité 16. La seconde extrémité 16 présente également une forme de pan coupé 18.The second end 16 is closed by a thermosealed cover 17, for example. The cover 17 can also be fitted into the second end 16. The second end 16 also has a cutaway shape 18.

Le tube protecteur 14 peut, par exemple, être réalisé en matière plastique et peut éventuellement être recouvert extérieurement, dans ses parties visibles (c'est-à-dire dans ses parties proches de la deuxième extrémité 16) par une virole métallique 19 décorative.The protective tube 14 can, for example, be made of plastic and can optionally be covered externally, in its visible parts (that is to say in its parts close to the second end 16) by a decorative metal ferrule 19.

Le tube protecteur 14 comporte une cupule 20 réalisée par exemple en matière plastique.The protective tube 14 includes a cup 20 made for example of plastic.

La cupule 20 présente un fond 21 et une paroi latérale 22 ayant une forme générale cylindrique de révolution centrée sur l'axe X. Cette paroi latérale 22 s'étend depuis le fond 21 jusqu'à une extrémité libre 23 en direction de la seconde extrémité 16 du tube protecteur 14.The cup 20 has a bottom 21 and a side wall 22 having a generally cylindrical shape of revolution centered on the axis X. This side wall 22 extends from the bottom 21 to a free end 23 in the direction of the second end 16 of the protective tube 14.

Le fond 21 de la cupule 20 est doté d'une ouverture centrale 24, ainsi que d'un téton central 25 formé d'une seule pièce sous le fond 21 de la cupule 20.The bottom 21 of the cup 20 has a central opening 24, as well as a central stud 25 formed in one piece under the bottom 21 of the cup 20.

Le mécanisme 13 comporte en outre un dispositif de manœuvre 26 qui inclut une base 27 qui forme la partie inférieure du mécanisme 13.The mechanism 13 also comprises an operating device 26 which includes a base 27 which forms the lower part of the mechanism 13.

La base 27 comporte un fond 28 présentant une ouverture traversante 29 cylindrique d'axe X, alignée avec l'ouverture centrale 24 de la cupule 20.The base 27 has a bottom 28 having a cylindrical through opening 29 of axis X, aligned with the central opening 24 of the cup 20.

La base 27 peut comporter une portion amincie 30 sur laquelle pourra venir s'emboiter un capot protecteur de tube de rouge à lèvres.The base 27 may include a thinned portion 30 on which a protective cover for the lipstick tube may fit.

La base 27 peut être monté rotative par rapport au tube protecteur 14. Pour ce faire, le mécanisme 13 comporte une vis 31 solidaire d'un coulisseau 32, qui coulisse selon l'axe X à l'intérieur du tube protecteur 14, et un écrou 33 qui est vissé sur la vis 31 et qui est solidarisé en rotation avec la base 27.The base 27 can be rotatably mounted relative to the protective tube 14. To do this, the mechanism 13 comprises a screw 31 secured to a slide 32, which slides along the axis X inside the protective tube 14, and a nut 33 which is screwed onto the screw 31 and which is secured in rotation with the base 27.

Le cœur de l'invention n'étant ni dans la réalisation du mécanisme 13 ni dans son fonctionnement, ce dernier ne sera pas décrit. Toutefois, le fonctionnement du mécanisme 13 est le même que celui décrit dans la demande de brevet FR 2 952 911 antérieure, dont le contenu est incorporé ici par référence.Since the heart of the invention is neither in the production of the mechanism 13 nor in its operation, the latter will not be described. However, the operation of the mechanism 13 is the same as that described in the patent application FR 2 952 911 the content of which is incorporated herein by reference.

Le dispositif de remplissage d'un tube applicateur de rouge à lèvres va maintenant être décrit en faisant référence aux figures 3 à 10.The device for filling a lipstick applicator tube will now be described with reference to figures 3 to 10 .

La figure 3 montre un dispositif 34 de remplissage, qui est conçu pour accueillir, d'une part, une capsule 1 telle que montrée en figure 1 et, d'autre part, un mécanisme 13 tel que montré en figure 2.The figure 3 shows a filling device 34, which is designed to accommodate, on the one hand, a capsule 1 as shown in figure 1 and, on the other hand, a mechanism 13 as shown in figure 2 .

Le dispositif 34 de remplissage comprend un compartiment 35 qui est réalisé sur une face avant 36 du dispositif 34 et qui est conçu pour accueillir une capsule 1.The filling device 34 comprises a compartment 35 which is produced on a front face 36 of the device 34 and which is designed to accommodate a capsule 1.

Le compartiment 35 est fermé par un carter 37 de protection qui est monté mobile entre une position fermée (illustrée en figure 3) et une position ouverte (illustrée en figure 4) par pivot autour d'une charnière 38 d'axe Z sensiblement vertical.The compartment 35 is closed by a protective casing 37 which is mounted movable between a closed position (illustrated in figure 3 ) and an open position (illustrated in figure 4 ) by pivot around a hinge 38 of substantially vertical axis Z.

Une poignée 39, réalisée en une seule pièce avec le carter 37, est prévue à l'opposé de la charnière 38, afin de faciliter la préhension du carter par une opératrice 100 (ou un opérateur) pour son ouverture.A handle 39, made in one piece with the casing 37, is provided opposite the hinge 38, in order to facilitate the gripping of the casing by an operator 100 (or an operator) for its opening.

Un système à aimants 40 placés entre le carter et le dispositif 34, de part et d'autre de la poignée 39, permet de maintenir le carter 37 en position fermée.A magnet system 40 placed between the housing and the device 34, on either side of the handle 39, keeps the housing 37 in the closed position.

Le dispositif 34 comporte également sur une face latérale 41, un écran d'affichage 42. Cet écran d'affichage a pour fonction de donner à une opératrice 100 des informations sur l'état de fonctionnement du dispositif 34 de remplissage, ou bien des instructions pour faire fonctionner le dispositif 34, ou bien encore pour lui indiquer l'état d'avancement du processus de remplissage mis en œuvre par le dispositif 34 de remplissage. En d'autres termes, l'écran 42 permet de fournir des informations à une opératrice se servant du dispositif.The device 34 also comprises on a side face 41, a display screen 42. This display screen has the function of giving an operator 100 information on the operating state of the filling device 34, or else instructions to operate the device 34, or else to indicate to it the state of progress of the filling process implemented by the filling device 34. In other words, the screen 42 makes it possible to supply information to an operator using the device.

L'écran 42 pourrait également permettre de commander le fonctionnement du dispositif 34 en étant tactile et équipé de moyens adaptés, pour commander la mise en œuvre de certaines étapes par le toucher de certaines zones prédéterminées sur ledit écran 42.The screen 42 could also make it possible to control the operation of the device 34 by being tactile and equipped with suitable means, for controlling the implementation of certain steps by touching certain predetermined areas on said screen 42.

La face latérale 41 du dispositif 34 comporte également un tiroir de récupération 43 où sont récupérées des têtes sécables 11 des capsules 1 après avoir été sectionnées lors du processus de remplissage d'un mécanisme 13 de tube applicateur de rouge à lèvres.The lateral face 41 of the device 34 also includes a recovery drawer 43 from which the breakable heads 11 of the capsules 1 are recovered after having been cut during the filling process of a mechanism 13 of lipstick applicator tube.

Le tiroir de récupération 43 s'ouvre latéralement et est de préférence amovible de manière à pouvoir être vidé sans avoir à toucher les têtes sécables présentant des résidus de rouge à lèvres.The recovery drawer 43 opens laterally and is preferably removable so that it can be emptied without having to touch the breakable heads with lipstick residue.

La face latérale 41 comprend enfin une trappe 46 permettant d'accéder aux éléments internes du dispositif 34 de remplissage afin de permettre leur maintenance.The lateral face 41 finally comprises a hatch 46 allowing access to the internal elements of the filling device 34 in order to allow their maintenance.

Sur la face avant 36 du dispositif 34, sous le compartiment 35 à capsule, se trouve également un second tiroir 44 permettant d'insérer un mécanisme 13 dans le dispositif de remplissage 34.On the front face 36 of the device 34, under the capsule compartment 35, there is also a second drawer 44 allowing a mechanism 13 to be inserted into the filling device 34.

Les tiroirs 43 et 44 sont tous deux équipés d'une poignée 45 facilitant sa préhension par une opératrice 100.The drawers 43 and 44 are both equipped with a handle 45 facilitating its gripping by an operator 100.

Le compartiment 35, conçu pour accueillir une capsule 1, est équipé d'un logement d'accueil 47, de forme sensiblement complémentaire à celle d'une capsule 1. Autrement dit, la forme interne du logement 47 est sensiblement cylindrique.The compartment 35, designed to receive a capsule 1, is equipped with a reception housing 47, of shape substantially complementary to that of a capsule 1. In other words, the internal shape of the housing 47 is substantially cylindrical.

Le logement 47 présente une extrémité ouverte vers l'intérieur du compartiment 35 pour y permettre l'introduction d'une capsule 1 par une opératrice 100 (voir figure 5).The housing 47 has one end open towards the inside of the compartment 35 to allow the introduction of a capsule 1 by an operator 100 (see figure 5 ).

Le logement 47 est ménagé au moins partiellement dans un boitier 48, et qui est fixé sous un fond 49 du compartiment, le fond 49 étant sensiblement horizontal lorsque le dispositif 34 repose sur une surface horizontale.The housing 47 is formed at least partially in a housing 48, and which is fixed under a bottom 49 of the compartment, the bottom 49 being substantially horizontal when the device 34 rests on a horizontal surface.

Le boitier 48 est retenu sous le fond 49 du compartiment 35 par une tête cylindrique 50 à laquelle il est attaché (par exemple au moyen de vis 51), la tête cylindrique 50 étant fixée sur le fond 49 du compartiment 35. Autrement dit, la tête cylindrique 50 et le boitier 48 se situent de part et d'autre d'une paroi formant le fond 49 du compartiment 35.The housing 48 is retained under the bottom 49 of the compartment 35 by a cylindrical head 50 to which it is attached (for example by means of screws 51), the cylindrical head 50 being fixed on the bottom 49 of the compartment 35. In other words, the cylindrical head 50 and the housing 48 are located on either side of a wall forming the bottom 49 of the compartment 35.

Ainsi, seule la tête 50 du boîtier 48 est visible dans le compartiment 35, et le logement 47 traverse également la tête 50 du boitier.Thus, only the head 50 of the housing 48 is visible in the compartment 35, and the housing 47 also passes through the head 50 of the housing.

Comme on peut le voir sur la figure 6, lorsque la capsule 1 est insérée dans le logement 47, la première extrémité 3 du cylindre 2 est saillante au dessus de la surface supérieure 52 de la tête 50 du boitier. Cela permet notamment de faciliter la saisie de la capsule pour la retirer du logement 47.As we can see on the figure 6 , when the capsule 1 is inserted into the housing 47, the first end 3 of the cylinder 2 is projecting above the upper surface 52 of the head 50 of the housing. This makes it possible in particular to facilitate the gripping of the capsule to remove it from the housing 47.

Afin de permettre cette position saillante de la première extrémité 3, le logement 47 présente une profondeur p qui est inférieure à la hauteur h du cylindre 2 de la capsule 1.In order to allow this projecting position of the first end 3, the housing 47 has a depth p which is less than the height h of the cylinder 2 of the capsule 1.

De plus, le logement 47 présente un fond 53 de forme tronconique, percé d'une ouverture traversante 54. L'ouverture traversante 54 présente une section supérieure de diamètre supérieur au diamètre de la tête sécable 11, de manière à être traversée par ladite tête sécable. Quant au fond 53, il présente une forme sensiblement tronconique dans laquelle peut reposer la seconde extrémité 3 du cylindre 2 de la capsule 1.In addition, the housing 47 has a bottom 53 of frustoconical shape, pierced with a through opening 54. The through opening 54 has an upper section of diameter greater than the diameter of the breakable head 11, so as to be crossed by said head breakable. As for the bottom 53, it has a substantially frustoconical shape in which the second end 3 of the cylinder 2 of the capsule 1 can rest.

Le boitier 48, montré plus en détail sur la figure 7, comporte au moins une résistance électrique de chauffage 55 répartie uniformément autour du logement 47 et sur au moins une grande partie de sa profondeur p (au moins la moitié de la profondeur p du logement 47).The case 48, shown in more detail on the figure 7 , comprises at least one electrical heating resistor 55 distributed uniformly around the housing 47 and over at least a large part of its depth p (at least half the depth p of the housing 47).

Le boitier 48 est également équipé de deux lames tranchantes 56 (visibles sur la figure 9c), chacune des lames 56 étant fixée sur un poussoir 57 monté mobile en déplacement entre une position de coupe et une position de repos.The case 48 is also equipped with two sharp blades 56 (visible on the figure 9c ), each of the blades 56 being fixed on a pusher 57 mounted movable in displacement between a cutting position and a rest position.

Les poussoirs 57 sont maintenus en position de repos en étant chacun contraint par un ressort 58. Les deux poussoirs 57 sont amenés en position de coupe lorsqu'ils sont poussés par deux galets cylindriques 59 qui sont déplacés.The pushers 57 are held in the rest position, each being constrained by a spring 58. The two pushers 57 are brought into the cutting position when they are pushed by two cylindrical rollers 59 which are moved.

Le déplacement des galets cylindriques 59 sera décrit par la suite. Les galets 59 sont fixés à un élément du tiroir 44 du dispositif 34 de remplissage, qui sera décrit par la suite.The displacement of the cylindrical rollers 59 will be described later. The rollers 59 are fixed to an element of the drawer 44 of the filling device 34, which will be described later.

Les deux lames 56 sont ainsi montées mobiles entre une position inactive (correspondant à la position de repos des poussoirs 57) et une position active (correspondant à la position de coupe des poussoirs 57) suivant laquelle les lames 56 ouvrent la buse 9 de sortie.The two blades 56 are thus mounted movable between an inactive position (corresponding to the rest position of the pushers 57) and an active position (corresponding to the cutting position of the pushers 57) according to which the blades 56 open the outlet nozzle 9.

Par ailleurs, l'ensemble constitué par les poussoirs 57, les ressorts 58 et les galets cylindriques 59 constitue un actionneur apte à déplacer les lames entre ladite position active et ladite position inactive, et inversement.Furthermore, the assembly constituted by the pushers 57, the springs 58 and the cylindrical rollers 59 constitutes an actuator capable of moving the blades between said active position and said inactive position, and vice versa.

Le boitier 48, comportant le logement 47, et équipé de moyens de chauffage 55 et de moyens 56 et 57 assurant l'ouverture de la buse 9 de sortie de la capsule 1, constitue des moyens de préparation de la capsule, permettant d'une part de fluidifier son contenu (c'est-à-dire le raisin de rouge à lèvres 10) par chauffage, et d'ouvrir la capsule pour en extraire le contenu fluidifié.The housing 48, comprising the housing 47, and equipped with heating means 55 and means 56 and 57 ensuring the opening of the nozzle 9 for exit from the capsule 1, constitutes means for preparing the capsule, allowing on the one hand to fluidize its content (that is to say the lipstick grape 10) by heating, and to open the capsule to extract the fluidized content therefrom.

Le dispositif de remplissage 34 comporte par ailleurs, conformément à l'invention, des moyens de coulage du rouge à lèvres 10 qui vont maintenant être décrits en faisant référence aux figures 3, 4, 9a et 9b.The filling device 34 also comprises, in accordance with the invention, means for pouring the lipstick 10 which will now be described with reference to the figures 3 , 4 , 9a and 9b .

Les moyens de coulage, permettant notamment d'expulser le rouge à lèvres 10 hors de la capsule 1, comportent une tige 60 qui est orientée verticalement dans le compartiment 35.The casting means, making it possible in particular to expel the lipstick 10 from the capsule 1, comprise a rod 60 which is oriented vertically in the compartment 35.

La tige est montée mobile entre une position inactive (montrée en figures 3 et 4) suivant laquelle elle est éloignée du boitier 48, rangée (ou escamotée) dans une rainure 61 ménagée dans une face latérale 62 du compartiment 35, et une position active suivant laquelle une extrémité 63 de la tige 60 est apte à exercer une pression sur le piston 6 de la capsule 1 (voir figures 9a et 9b).The rod is mounted movable between an inactive position (shown in figures 3 and 4 ) according to which it is remote from the housing 48, stored (or retracted) in a groove 61 formed in a lateral face 62 of the compartment 35, and an active position according to which one end 63 of the rod 60 is capable of exerting pressure on the piston 6 of capsule 1 (see figures 9a and 9b ).

Pour passer de la position active à la position inactive de la tige, cette dernière est reliée à un vérin (non représenté) permettant de la déplacer verticalement la tige. Le vérin est placé dans le corps du dispositif 34 de remplissage. De plus, l'ensemble constitué par la tige 60 associée au vérin est également monté mobile en déplacement horizontal pour amener l'axe de la tige 60 dans l'axe du logement 47 du boitier 48.To pass from the active position to the inactive position of the rod, the latter is connected to a jack (not shown) allowing the rod to be moved vertically. The cylinder is placed in the body of the filling device 34. In addition, the assembly constituted by the rod 60 associated with the jack is also mounted movable in horizontal displacement to bring the axis of the rod 60 into the axis of the housing 47 of the housing 48.

Les moyens assurant le déplacement horizontal de la tige et du vérin ne sont pas visibles sur les figures car ils sont également enfermés dans le corps du dispositif 34. Ils peuvent être réalisés par un système à vérin, ou tout autre moyen bien connu par l'homme du métier.The means ensuring the horizontal displacement of the rod and of the jack are not visible in the figures because they are also enclosed in the body of the device 34. They can be produced by a jack system, or any other means well known by the skilled in the art.

Afin de permettre de couler le rouge à lèvres 10 dans un mécanisme 13 de tube applicateur de rouge à lèvres, le dispositif de remplissage 34 comporte un second logement 64, apte à accueillir un mécanisme 13 placé tête en bas (à l'envers, c'est-à-dire avec le fond 28 de la base 27 orienté vers le haut) et à le disposer dans l'axe du logement 47 (c'est-à-dire dans l'axe de la capsule 1 quand elle est placée dans le logement 47) afin de permettre son remplissage par l'ouverture traversante 29 du mécanisme située dans le fond 28 de la base 27 de ce dernier.In order to allow lipstick 10 to flow into a mechanism 13 of a lipstick applicator tube, the filling device 34 has a second housing 64, capable of accommodating a mechanism 13 placed upside down (upside down, c (i.e. with the bottom 28 of the base 27 facing up) and to arrange it in the axis of the housing 47 (i.e. in the axis of the capsule 1 when it is placed in the housing 47) to allow its filling through the through opening 29 of the mechanism located in the bottom 28 of the base 27 of the latter.

Le second logement 64 est ménagé dans le second tiroir 44 du dispositif de remplissage, comme montré en particulier sur les figures 8a et 8b.The second housing 64 is formed in the second drawer 44 of the filling device, as shown in particular on the figures 8a and 8b .

Le tiroir 44 comporte un plateau 66 sensiblement horizontal, dans lequel est ménagée une ouverture traversante 67 de forme allongée dans la direction d'ouverture du tiroir 44.The drawer 44 comprises a substantially horizontal plate 66, in which a through opening 67 of elongated shape is formed in the opening direction of the drawer 44.

Le logement 64 est réalisé par une bague 65 qui est fixée dans l'ouverture traversante 67, à son extrémité 68 orientée vers la poignée 45 du tiroir 44.The housing 64 is produced by a ring 65 which is fixed in the through opening 67, at its end 68 oriented towards the handle 45 of the drawer 44.

L'orientation de l'ouverture traversante 67 de forme allongée et la position de la bague 65 dans ladite ouverture 67 permettent l'évacuation de la tête sécable 11 à travers l'ouverture 67 (lorsqu'elle est coupée, lors de la fermeture du tiroir 44) juste avant le positionnement du mécanisme 13 dans l'axe du logement 47 du boitier 48 (autrement dit au droit de la buse de sortie de la capsule - voir figure 9a).The orientation of the through opening 67 of elongated shape and the position of the ring 65 in said opening 67 allow the breakable head 11 to be evacuated through the opening 67 (when it is cut, when the drawer 44) just before the positioning of the mechanism 13 in the axis of the housing 47 of the housing 48 (in other words at the right of the capsule outlet nozzle - see figure 9a ).

Au voisinage d'une extrémité 69 de l'ouverture traversante 67, extrémité 69 qui est opposée à l'extrémité 68, et de part et d'autre d'un axe de symétrie de l'ouverture traversante 67, le plateau 66 comporte deux colonnes 70. Une seule colonne est visible sur les figures 7, 9a et 9b qui montrent schématiquement le tiroir en vue de côté.In the vicinity of one end 69 of the through opening 67, end 69 which is opposite to the end 68, and on either side of an axis of symmetry of the through opening 67, the plate 66 has two columns 70. Only one column is visible on the figures 7 , 9a and 9b which schematically show the drawer in side view.

Chacune des colonnes 70 porte, à son extrémité libre 71, un des deux galets cylindriques 59 permettant de déplacer les poussoirs 57, assurant l'ouverture de la buse 9 de la capsule 1 par découpe de la tête sécable 11.Each of the columns 70 carries, at its free end 71, one of the two cylindrical rollers 59 making it possible to move the pushers 57, ensuring the opening of the nozzle 9 of the capsule 1 by cutting out the breakable head 11.

Les galets cylindriques 59 et les colonnes sont coaxiaux.The cylindrical rollers 59 and the columns are coaxial.

Au dessus de chacun des galets cylindriques 59, un élément 72 buttoir est également fixé de façon coaxiale. L'élément buttoir 72 empêche une ouverture complète du tiroir 44 en venant butter contre une extrémité 73 d'une paroi 74 du dispositif de remplissage 34.Above each of the cylindrical rollers 59, a stopper element 72 is also fixed coaxially. The stopper element 72 prevents the drawer 44 from being completely opened by coming against an end 73 of a wall 74 of the filling device 34.

La paroi 74 vient sensiblement au droit d'une paroi 75 du tiroir 44 quand le tiroir 44 est fermé.The wall 74 comes substantially in line with a wall 75 of the drawer 44 when the drawer 44 is closed.

Enfin, le plateau 66 du tiroir 44 est équipé d'un dispositif halogène 76, orienté vers le haut.Finally, the tray 66 of the drawer 44 is equipped with a halogen device 76, oriented upwards.

Le dispositif halogène 76 est prévu à une extrémité 77 du plateau 66, extrémité 77 qui est située sensiblement dans le fond du tiroir 44.The halogen device 76 is provided at one end 77 of the tray 66, end 77 which is situated substantially in the bottom of the drawer 44.

Le dispositif halogène 76 permet de fluidifier le rouge à lèvres 10 situé dans l'extrémité 4 de la capsule 1, c'est-à-dire le rouge à lèvres 10 qui se trouve au voisinage de la tête sécable 11. En effet, il a été constaté que la résistance de chauffage 55 qui se trouve dans le boitier 48 n'était pas suffisante pour fluidifier de manière homogène le rouge à lèvres 10 dans la capsule 1. Si le rouge à lèvres 10 est mal fluidifié au voisinage de la buse 9 de sortie de la capsule 1, alors :

  • ou bien le rouge à lèvres s'écoule mal,
  • ou bien il se forme une accumulation de matière non esthétique sur l'opercule 77 situé dans le fond du mécanisme, et donc sur l'extrémité du bâton de rouge à lèvres qui sera formé, ce qui est inacceptable.
The halogen device 76 makes it possible to thin the lipstick 10 located in the end 4 of the capsule 1, that is to say the lipstick 10 which is located in the vicinity of the breakable head 11. In fact, it has been found that the heating resistor 55 which is located in the housing 48 was not sufficient to uniformly fluidize the lipstick 10 in the capsule 1. If the lipstick 10 is poorly fluidized in the vicinity of the nozzle 9 for output from the capsule 1, then:
  • or the lipstick doesn't flow well,
  • or an accumulation of non-aesthetic material is formed on the cover 77 located in the bottom of the mechanism, and therefore on the end of the lipstick stick which will be formed, which is unacceptable.

Afin d'assurer un bon positionnement du dispositif halogène 76 au droit du logement 47, et donc de la tête sécable 11 quand la capsule 1 se trouve dans le logement 47, le dispositif de remplissage 34 conforme à l'invention peut comporter un capteur de positionnement 78 du dispositif halogène.In order to ensure correct positioning of the halogen device 76 in line with the housing 47, and therefore of the breakable head 11 when the capsule 1 is in the housing 47, the filling device 34 according to the invention may include a positioning 78 of the halogen device.

Quand le capteur 78 détecte la présence du dispositif halogène en face de lui, il commande son allumage (voir figure 7).When the sensor 78 detects the presence of the halogen device in front of it, it controls its ignition (see figure 7 ).

Enfin, le dispositif de remplissage 34 comporte des moyens de refroidissement 79 du mécanisme rempli de rouge à lèvres 10.Finally, the filling device 34 includes cooling means 79 for the mechanism filled with lipstick 10.

Les moyens de refroidissement 79 sont prévus au voisinage du logement 64 quand le tiroir 44 est en position fermée. De cette façon, les moyens de refroidissement 79 sont relativement proches du mécanisme 13 afin de refroidir et solidifier le rouge à lèvres 10 fluidifié qui se trouve dans le mécanisme 13 lors de la réalisation d'un tube de rouge à lèvres.The cooling means 79 are provided in the vicinity of the housing 64 when the drawer 44 is in the closed position. In this way, the cooling means 79 are relatively close to the mechanism 13 in order to cool and solidify the fluidized lipstick 10 which is in the mechanism 13 during the production of a tube of lipstick.

Les moyens de refroidissement 79 peuvent comprendre un système 80 de ventilation ou de soufflerie, symbolisé schématiquement par des ventilateurs sur la figure 10.The cooling means 79 may comprise a ventilation or blower system 80, symbolized schematically by fans on the figure 10 .

On va maintenant décrire le procédé conforme à l'invention, qui utilise le dispositif de remplissage 34 qui vient d'être décrit, afin de réaliser un tube de rouge à lèvres sur demande, en faisant référence aux figures 3 à 12.We will now describe the process according to the invention, which uses the filling device 34 which has just been described, in order to produce a tube of lipstick on request, with reference to the figures 3 to 12 .

Initialement, le dispositif de remplissage 34 conforme à l'invention se présente tel qu'illustré en figure 3, c'est-à-dire avec son carter de protection 37 en position fermée.Initially, the filling device 34 according to the invention is present as illustrated in figure 3 , that is to say with its protective casing 37 in the closed position.

Un tel dispositif peut être mis à disposition des clientes en boutique ou être utilisé par des opératrices en boutique, les opératrices réalisant alors sur demande des clientes, le remplissage de mécanismes de tubes de rouges à lèvres.Such a device can be made available to customers in the boutique or be used by operators in the boutique, the operators then carrying out, on request, clients, filling lipstick tube mechanisms.

Initialement, l'écran d'affichage 42 du dispositif de remplissage 34 indique à une opératrice 100 si le dispositif 34 est prêt pour réaliser un remplissage ou si éventuellement une maintenance est requise.Initially, the display screen 42 of the filling device 34 indicates to an operator 100 if the device 34 is ready for filling or if possibly maintenance is required.

Lorsque qu'une cliente souhaite un tube de rouge à lèvres personnalisé, elle choisit tout d'abord sur un présentoir, comportant une série de capsules 1 de différentes couleurs, la couleur de rouge à lèvres 10 qu'elle souhaite.When a client wishes a personalized lipstick tube, she first chooses on a display, comprising a series of capsules 1 of different colors, the lipstick color 10 that she wishes.

L'opératrice 100 saisit alors une capsule 1 de la couleur désirée.The operator 100 then grasps a capsule 1 of the desired color.

L'opératrice 100 ouvre alors le carter 37 de protection du dispositif de remplissage 34 (figure 4) et elle dispose, dans le logement 47, une capsule 1, tête en bas (voir figure 5).The operator 100 then opens the casing 37 for protecting the filling device 34 ( figure 4 ) and it has, in the housing 47, a capsule 1, upside down (see figure 5 ).

L'extrémité 3 de la capsule 1 se trouve alors saillante au dessus de la surface supérieure 52 de la tête 50 du boitier 48.The end 3 of the capsule 1 is then projecting above the upper surface 52 of the head 50 of the case 48.

L'opératrice 100 ferme alors le carter 37 de protection.The operator 100 then closes the protective casing 37.

Conformément à l'invention, le rouge à lèvres 10 contenu dans la capsule est alors fluidifié suivant une étape préparatoire, par chauffage de la capsule (figure 7). Ce chauffage peut être commandé par l'opératrice 100 via l'écran 42 qui peut être tactile.In accordance with the invention, the lipstick 10 contained in the capsule is then fluidized according to a preparatory step, by heating the capsule ( figure 7 ). This heating can be controlled by the operator 100 via the screen 42 which can be tactile.

Le chauffage peut également être automatique lorsque la présence d'une capsule 1 est détectée dans le logement 47 et lorsque le dispositif halogène 76 est correctement placé en face du capteur 78.Heating can also be automatic when the presence of a capsule 1 is detected in the housing 47 and when the halogen device 76 is correctly placed opposite the sensor 78.

Pour déclencher le chauffage, il peut être indiqué à l'opératrice 100, via l'écran 42, de tirer légèrement le tiroir 44 afin de le disposer suivant une première position de chauffage, position suivant laquelle le dispositif halogène 76 se trouve en face de la tête sécable 11 de la capsule 1, dépassant du logement 47.To start the heating, the operator 100 can be instructed, via the screen 42, to slightly pull the drawer 44 so as to arrange it in a first heating position, position in which the halogen device 76 is located opposite the breakable head 11 of the capsule 1, projecting from the housing 47.

L'écran peut alors indiquer un temps d'attente à l'opératrice 100, et indiquer lorsque l'étape de chauffage est terminée.The screen can then indicate a waiting time to the operator 100, and indicate when the heating step is complete.

Conformément à l'invention, l'étape de chauffage dure entre une et cinq minutes. De préférence, l'étape de chauffage dure quatre minutes.According to the invention, the heating step lasts between one and five minutes. Preferably, the heating step lasts four minutes.

La température à laquelle est chauffée la capsule est comprise sensiblement entre 80 et 100°C, de sorte que le produit atteigne une température assurant sa fluidification (environ 75 °C). La température de chauffage est idéalement sensiblement de 90°C.The temperature to which the capsule is heated is substantially between 80 and 100 ° C, so that the product reaches a temperature ensuring its fluidification (about 75 ° C). The heating temperature is ideally approximately 90 ° C.

Quand le chauffage est terminé, l'écran 42 indique à l'opératrice 100 qu'un mécanisme 13 de rouge à lèvres peut être inséré dans le dispositif de remplissage 34.When the heating is finished, the screen 42 indicates to the operator 100 that a lipstick mechanism 13 can be inserted in the filling device 34.

L'opératrice 100 ouvre alors le tiroir 44 et insère un mécanisme 13 dans le logement 64 du tiroir, le mécanisme 13 étant placé également tête en bas, c'est-à-dire avec la base 27 du dispositif de manœuvre orientée vers le haut (voir figures 8a et 8b).The operator 100 then opens the drawer 44 and inserts a mechanism 13 into the housing 64 of the drawer, the mechanism 13 also being placed upside down, that is to say with the base 27 of the operating device facing upwards (see figures 8a and 8b ).

L'opératrice 100 ferme alors le tiroir 44. En réalisant cette fermeture, plusieurs opérations sont actionnées simultanément :
D'une part, la fermeture du tiroir 44 entraîne en déplacement les deux colonnes 70 portant les galets cylindriques 59 (figure 9c), ce qui déplace les deux poussoirs 57 et sectionne l'extrémité de la tête sécable 11 de la capsule 1. La tête sécable 11 tombe à travers l'ouverture 67 dans le tiroir de récupération 43 (le tiroir 43 est représenté très symboliquement par un godet sur les figures 9a et 9b, afin d'en simplifier la lecture).The operator 100 then closes the drawer 44. By carrying out this closure, several operations are actuated simultaneously:
On the one hand, closing the drawer 44 moves the two columns 70 carrying the cylindrical rollers 59 ( figure 9c ), which moves the two pushers 57 and cuts off the end of the breakable head 11 of the capsule 1. The breakable head 11 falls through the opening 67 in the recovery drawer 43 (the drawer 43 is very symbolically represented by a bucket on figures 9a and 9b , in order to simplify the reading).

D'autre part, quand le tiroir 44 est correctement fermé, cette fermeture est détectée et la tige 60 est déplacée, via le dispositif de déplacement horizontal et le vérin assurant son déplacement vertical, et la tige 60 s'insère dans la capsule 1 en appuyant sur le piston 6.On the other hand, when the drawer 44 is correctly closed, this closure is detected and the rod 60 is moved, via the horizontal displacement device and the jack ensuring its vertical displacement, and the rod 60 is inserted into the capsule 1 in pressing the piston 6.

Le rouge à lèvres 10 fluidifié est alors expulsé de la capsule 1 par la buse de sortie 9, et se déverse dans l'ouverture traversante 29 du fond du mécanisme 13 (voir figure 9b).The fluidized lipstick 10 is then expelled from the capsule 1 by the outlet nozzle 9, and pours into the through opening 29 of the bottom of the mechanism 13 (see figure 9b ).

Lorsque le piston 6 atteint le fond de la capsule 1, la descente de la tige 60 est arrêtée.When the piston 6 reaches the bottom of the capsule 1, the descent of the rod 60 is stopped.

La tige 60 remonte alors et revient en position initiale escamotée dans sa rainure de rangement 61.The rod 60 then rises and returns to the initial position retracted in its storage groove 61.

Une étape de refroidissement est alors déclenchée automatiquement par le dispositif de remplissage 34.A cooling step is then automatically triggered by the filling device 34.

L'écran 42 indique alors à l'opératrice 100 que l'étape de refroidissement est en cours. Il peut également indiquer un décompte du temps de refroidissement du mécanisme 13 rempli de rouge à lèvres 10.The screen 42 then indicates to the operator 100 that the cooling step is in progress. It can also indicate a countdown of the cooling time of the mechanism 13 filled with lipstick 10.

Dans le cadre du procédé conforme à l'invention, l'étape de refroidissement, illustrée schématiquement en figure 10, est réalisée pendant un intervalle de temps compris sensiblement entre une et cinq minutes. De préférence, l'étape de refroidissement dure sensiblement quatre minutes.In the context of the process according to the invention, the cooling step, illustrated schematically in figure 10 , is performed during an interval of time substantially between one and five minutes. Preferably, the cooling step lasts substantially four minutes.

Concrètement, l'étape de refroidissement est réalisée par soufflage d'air froid sur la virole 19 du mécanisme 13, ce qui permet de solidifier le rouge à lèvres 10 dans le tube protecteur 14 du mécanisme 13.Concretely, the cooling step is carried out by blowing cold air onto the shell 19 of the mechanism 13, which makes it possible to solidify the lipstick 10 in the protective tube 14 of the mechanism 13.

Lorsque le refroidissement est terminé, l'écran 42 l'indique à l'opératrice 100 et l'invite à récupérer le mécanisme 13 rempli de rouge à lèvres 10 solidifié (voir figure 11).When the cooling is finished, the screen 42 indicates this to the operator 100 and invites her to recover the mechanism 13 filled with solidified lipstick 10 (see figure 11 ).

L'opératrice 100 retire alors manuellement l'opercule 17 qui ferme l'extrémité du tube protecteur 14, et actionne le mécanisme 13 afin de vérifier son fonctionnement et afin de contrôler visuellement le bâton de rouge à lèvres 10 solidifié.The operator 100 then manually removes the cover 17 which closes the end of the protective tube 14, and actuates the mechanism 13 in order to verify its operation and in order to visually check the solidified lipstick stick 10.

L'opératrice 100 insère alors le mécanisme 13 dans un tube de rouge à lèvres du choix de la cliente.The operator 100 then inserts the mechanism 13 into a tube of lipstick of the client's choice.

On comprend de la description qui précède comment l'invention permet de réaliser des tubes de rouges à lèvres personnalisés, du choix d'une cliente.We understand from the above description how the invention makes it possible to produce tubes of personalized lipsticks, of the choice of a client.

Par ailleurs, le dispositif de remplissage de l'invention se distingue en ce qu'il comprend une capsule amovible dans laquelle est inséré un piston obturant dont la fonction est d'expulser la composition de rouge à lèvre hors de la capsule après l'étape de chauffage.Furthermore, the filling device of the invention is distinguished in that it comprises a removable capsule in which is inserted a sealing piston whose function is to expel the lipstick composition out of the capsule after the step of heating.

L'insertion du piston à l'intérieur de la capsule présente l'avantage d'éviter tout contact entre des parties non amovibles du dispositif de remplissage et la composition de rouge à lèvres. Ainsi, une fois l'opération de coulage terminée, la capsule vide est retirée du dispositif sans que la composition ait contaminée une partie du dispositif, de sorte qu'il est possible pour l'opératrice de répéter une nouvelle opération de fabrication d'un bâton de rouge à lèvres, en insérant une nouvelle capsule 1, avantageusement d'une couleur et/ou d'une texture différente, et un nouveau mécanisme 13, sans qu'il soit besoin au préalable de nettoyer des parties de l'appareil qui aurait pu être précédemment contaminées par la composition.The insertion of the piston inside the capsule has the advantage of avoiding any contact between non-removable parts of the filling device and the lipstick composition. Thus, once the casting operation is complete, the empty capsule is removed from the device without the composition having contaminated part of the device, so that it is possible for the operator to repeat a new operation for manufacturing a lipstick stick, by inserting a new capsule 1, advantageously of a different color and / or texture, and a new mechanism 13, without it will be necessary beforehand to clean parts of the apparatus which could have been previously contaminated by the composition.

En cela, le dispositif se distingue de machines qui comprennent des réservoirs ou des dispositifs dans lesquels le piston 6 serait fixé à la tige 60.In this, the device differs from machines which include reservoirs or devices in which the piston 6 is fixed to the rod 60.

Il devra être entendu que l'invention ne se limite pas spécifiquement au mode de réalisation représenté et décrit ci avant, et qu'elle s'étend à la mise en œuvre tout moyen équivalent, comme défini dans les revendications.It should be understood that the invention is not specifically limited to the embodiment shown and described above, and that it extends to the implementation of any equivalent means, as defined in the claims.
