Definitions

  • the invention relates to a mechanism for a cosmetic product, in particular a lipstick stick, and a receptacle comprising such a mechanism.
  • receptacles comprising a base in which is housed a mechanism containing a product are known.
  • a closure cap hermetically closes the upper opening of the mechanism and provides protection for the product.
  • Such a cosmetic receptacle mechanism is formed by an assembly of parts of revolution in which a main body, commonly called a guide, covers a cup intended to receive a stick of lipstick.
  • the cup is set in motion relative to the guide in order to move the stick inside the body, or to take it out through the opening of the guide to make it accessible to a user who wishes to apply makeup.
  • an outer sleeve made of metallic material is mounted around the guide to which it is firmly fixed.
  • Such mechanisms have a generally large number of parts, generating a large radial thickness between the edge of the grape and the outside of the mechanism.
  • These mechanisms are moreover complex, in particular for the so-called “guided” mechanisms and used for a so-called soft grape formulation.
  • the stick needs to be in direct contact with a part of the mechanism to ensure that it is held in place and relatively smooth to prevent it from being damaged, in particular when it is moved for the application of the cosmetic product.
  • An alternative solution would consist of separating the sleeve and considering two different dies: a die specific to the treatment of the metallic material and a die specific to the treatment of the synthetic material of the rest of the mechanism. Such a solution would be expensive in terms of sorting and would require being able to separate the elements of the mechanism from each other easily.

Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne un mécanisme pour produit cosmétique, notamment un raisin de rouge à lèvres, et un réceptacle comportant un tel mécanisme.The invention relates to a mechanism for a cosmetic product, in particular a lipstick stick, and a receptacle comprising such a mechanism.

Arrière-plan techniqueTechnical background

Dans le domaine de produits cosmétiques, on connaît des réceptacles comprenant une base dans laquelle est logée un mécanisme contenant un produit. Un capot de fermeture vient fermer hermétiquement l'ouverture supérieure du mécanisme et apporter une protection au produit.In the field of cosmetic products, receptacles comprising a base in which is housed a mechanism containing a product are known. A closure cap hermetically closes the upper opening of the mechanism and provides protection for the product.

Un tel mécanisme de réceptacle cosmétique est formé d'un assemblage de pièces de révolution dans lesquelles un corps principal communément appelé guide, recouvre une cupule destinée à recevoir un raisin de rouge à lèvres. La cupule est mise en mouvement par rapport au guide afin de déplacer le raisin à l'intérieur du corps, ou de l'en sortir par l'ouverture du guide pour le rendre accessible à un utilisateur qui souhaite se maquiller.Such a cosmetic receptacle mechanism is formed by an assembly of parts of revolution in which a main body, commonly called a guide, covers a cup intended to receive a stick of lipstick. The cup is set in motion relative to the guide in order to move the stick inside the body, or to take it out through the opening of the guide to make it accessible to a user who wishes to apply makeup.

De plus, pour préserver l'esthétisme, un manchon extérieur en matériau métallique est monté autour du guide auquel il est fixé solidairement.In addition, to preserve aesthetics, an outer sleeve made of metallic material is mounted around the guide to which it is firmly fixed.

De tels mécanismes ont un nombre de pièces généralement important, générant une épaisseur radiale importante entre le bord du raisin et l'extérieur du mécanisme. Ces mécanismes sont par ailleurs complexes notamment pour les mécanismes dit « guidés » et utilisés pour une formulation de raisin dite molle. Avec de telles formulations, le raisin nécessite d'être directement en contact avec une partie du mécanisme pour assurer son maintien et relativement lisse pour éviter son endommagement, en particulier lors de son déplacement pour l'application du produit cosmétique.Such mechanisms have a generally large number of parts, generating a large radial thickness between the edge of the grape and the outside of the mechanism. These mechanisms are moreover complex, in particular for the so-called “guided” mechanisms and used for a so-called soft grape formulation. With such formulations, the stick needs to be in direct contact with a part of the mechanism to ensure that it is held in place and relatively smooth to prevent it from being damaged, in particular when it is moved for the application of the cosmetic product.

On connaît différentes conceptions pour simplifier le nombre de pièces de ces mécanismes guidés comprenant au moins une cupule, une gaine spiralée qui comprend au moins une rainure hélicoïdale sur sa face extérieure et un manchon extérieur. La cupule est montée dans le manchon extérieur et entoure la gaine spiralée. Le manchon extérieur est réalisé en une pièce avec le guide du mécanisme dans sa partie inférieure. La gaine est également composée d'une molette à son extrémité inférieure permettant l'actionnement du mécanisme par un mouvement de rotation opposé de la molette et du manchon extérieur. De par leur conception ces mécanismes sont réalisés en grande partie en matière synthétique avec un manchon extérieur métallique pour des raisons esthétiques. Or le choix des matériaux conditionne leurs capacités à être recyclés dans la filière de recyclage dédiée. L'aspect réutilisation est également un aspect majeur, dès lors que le produit est souvent associé comme un produit de luxe avec une finition importante et une conception fonctionnelle de haute valeur, l'intérêt de pouvoir nettoyer et recycler le mécanisme en entier ou en partie sans l'endommager est un besoin de plus en plus important.Various designs are known to simplify the number of parts of these guided mechanisms comprising at least one cup, a spiral sheath which comprises at least one helical groove on its outer face and an outer sleeve. The cup is mounted in the outer sleeve and surrounds the spiral sheath. The outer sleeve is made of a piece with the mechanism guide in its lower part. The sheath is also composed of a wheel at its lower end allowing the mechanism to be actuated by an opposing rotational movement of the wheel and of the outer sleeve. By design, these mechanisms are made largely of synthetic material with an outer metal sleeve for aesthetic reasons. However, the choice of materials determines their ability to be recycled in the dedicated recycling channel. The reuse aspect is also a major aspect, since the product is often associated as a luxury product with an important finish and a high value functional design, the interest of being able to clean and recycle the mechanism in whole or in part without damaging it is an increasingly important need.

Le recyclage d'un tel mécanisme majoritairement réalisé en matériau synthétique en combinaison avec un tel manchon extérieur métallique implique une pollution dans la filière de recyclage dédiée au matériau synthétique. La présence de copeaux ou particules en matériaux métalliques indésirables non éliminés se retrouveraient ainsi dans la matière plastique recyclée rendant difficile l'utilisation d'un tel matériau recyclée.The recycling of such a mechanism mainly made of synthetic material in combination with such a metallic outer sleeve involves pollution in the recycling sector dedicated to the synthetic material. The presence of shavings or particles of undesirable metallic materials which have not been eliminated would thus be found in the recycled plastic material, making it difficult to use such a recycled material.

Une solution alternative consisterait à séparer le manchon et à considérer deux filières différentes : une filière propre au traitement du matériau métallique et une filière propre au traitement du matériau synthétique du reste du mécanisme. Une telle solution serait couteuse en termes de tri et nécessiterait de pouvoir séparer les éléments du mécanisme les uns des autres facilement.An alternative solution would consist of separating the sleeve and considering two different dies: a die specific to the treatment of the metallic material and a die specific to the treatment of the synthetic material of the rest of the mechanism. Such a solution would be expensive in terms of sorting and would require being able to separate the elements of the mechanism from each other easily.

Le document US 2 302 459 A divulgue un support cosmétique pour rouge à lèvres et matériau similaire.The document US 2,302,459A discloses a cosmetic carrier for lipstick and the like.

Dès lors, il apparait nécessaire de développer un mécanisme pour produits cosmétiques simplifié permettant de résoudre au moins une partie des inconvénients de l'état de la technique tout en bénéficiant également d'une chaine de valorisation en fin de cycle de vie avantageusement simple, fiable et peu onéreuse.Therefore, it appears necessary to develop a mechanism for simplified cosmetic products to solve at least some of the drawbacks of the state of the art while also benefiting from a value chain at the end of the life cycle that is advantageously simple, reliable and inexpensive.

Résumé de l'inventionSummary of the invention

La présente invention concerne un mécanisme pour un produit cosmétique selon la revendication 1. Des caractéristiques préférées de l'invention sont exposées dans les revendications dépendantes.The present invention relates to a mechanism for a cosmetic product according to claim 1. Preferred features of the invention are set out in the dependent claims.

La présente invention propose un mécanisme pour produit cosmétique, notamment un raisin de rouges à lèvres, comprenant une cupule configurée pour tenir ledit produit, ladite cupule comprenant au moins une patte flexible, une gaine comprenant une rainure hélicoïdale destinée à coopérer avec ladite cupule pour faire monter ou descendre le produit, un guide agencé autour de ladite gaine, ledit guide comprenant au moins une glissière verticale définissant une course de déplacement de la cupule et coopérant avec ladite au moins une patte flexible.The present invention proposes a mechanism for a cosmetic product, in particular a lipstick tube, comprising a cup configured to hold said product, said cup comprising at least one flexible tab, a sheath comprising a helical groove intended to cooperate with said cup to raise or lower the product, a guide arranged around said sheath, said guide comprising at least one vertical slide defining a stroke of displacement of the cup and cooperating with said at least one flexible tab.

Selon cet aspect de l'invention la gaine, la cupule et le guide sont réalisés à partir d'un type de matériau métallique.According to this aspect of the invention the sheath, the cup and the guide are made from a type of metallic material.

Ainsi, le mécanisme est un mécanisme simplifié avec un nombre de pièces réduit. De plus, l'utilisation de matériau métallique, notamment dans les mécanismes guidés, améliore le refroidissement de la formulation de produit cosmétique après son coulage ainsi que son aspect, permettant notamment de réduire la durée du cycle de fabrication.Thus, the mechanism is a simplified mechanism with a reduced number of parts. In addition, the use of metallic material, in particular in the guided mechanisms, improves the cooling of the cosmetic product formulation after its casting as well as its appearance, making it possible in particular to reduce the duration of the manufacturing cycle.

Par ailleurs, le mécanisme étant majoritairement métallique avec une gaine, une cupule et un guide en matériau métallique, il peut alors être traité dans une filière de recyclage dédié majoritairement au métal. Ceci permet de pourvoir réutiliser un matériau en plus grande quantité sans perte additionnelle ou rejet pour un gain optimisé. Ceci permet aussi de nettoyer et réutiliser le mécanisme en entier ou en partie sans l'endommager par un processus de nettoyage haute température.Furthermore, since the mechanism is mainly metallic with a sheath, a cup and a guide made of metallic material, it can then be treated in a recycling sector dedicated mainly to metal. This makes it possible to reuse a material in greater quantity without additional loss or rejection for an optimized gain. This also makes it possible to clean and reuse the mechanism in whole or in part without damaging it by a high temperature cleaning process.

Description détaillée de l'inventionDetailed description of the invention

Par convention, la direction « axiale » ou « longitudinale » correspond à celle de l'axe Y principal représenté sur les figures et la direction « radiale » est orthogonale à la direction axiale. Dans la description détaillée des figures qui suit, on utilisera de manière non limitative les termes « supérieure » et « inférieure » ou encore « haut » et « bas » en référence à la direction axiale. De la même manière, les termes « extérieur ou externe » et « intérieur ou interne » sont utilisés en référence à la direction radiale, un élément extérieur étant radialement plus éloigné de l'axe Y qu'un élément intérieur.By convention, the “axial” or “longitudinal” direction corresponds to that of the main axis Y shown in the figures and the “radial” direction is orthogonal to the axial direction. In the detailed description of the figures which follows, the terms “upper” and “lower” or even “top” and “bottom” will be used in a non-limiting manner with reference to the axial direction. Similarly, the terms "outer or outer" and "inner or inner" are used with reference to the radial direction, an outer member being radially farther from the Y axis than an inner member.

On a représenté sur les figures la à 1c, un exemple de mécanisme de produit cosmétique 11. Dans l'exemple de réalisation, le produit cosmétique 11 est un raisin de rouge à lèvres destiné à être appliqué par frottement, en variante un baume labial. Le réceptacle 100 comporte un capot 102 qui est associé à une base 104 présentant une forme complémentaire. Le réceptacle 100 présente un axe Y principal qui s'étend selon la direction axiale. De manière non limitative, le capot 102 et la base 104 du réceptacle 100 présentent une forme cylindrique de section circulaire.FIGS. 1a to 1c show an example of a cosmetic product mechanism 11. In the example embodiment, the cosmetic product 11 is a lipstick stick intended to be applied by rubbing, as a variant a lip balm. The receptacle 100 comprises a cover 102 which is associated with a base 104 having a complementary shape. The receptacle 100 has a main axis Y which extends in the axial direction. In a non-limiting manner, the cover 102 and the base 104 of the receptacle 100 have a cylindrical shape of circular section.

De préférence le capot 102 est amovible formant une pièce totalement indépendante de la base 104. Le capot 102 est susceptible d'occuper comme illustré sur la figure la une position de fermeture dans laquelle le capot est solidaire de la base 104. Le capot est susceptible d'occuper une position d'ouverture comme illustrée sur la figure 1b dans laquelle le capot 102 est séparé de la base 104 en vue notamment de permettre l'application du produit cosmétique.Preferably, the cover 102 is removable, forming a completely independent part of the base 104. The cover 102 is capable of occupying, as illustrated in FIG. 1a, a closed position in which the cover is secured to the base 104. The cover is capable to occupy an open position as illustrated in the figure 1b in which the cover 102 is separated from the base 104 with a view in particular to allowing the application of the cosmetic product.

Avantageusement tel qu'illustré sur les figures la à 1c et figure 8c, la partie inférieure du capot 102 coopère en position de fermeture avec une frette 103 disposée sur la partie supérieure 110 de la base 104. Le capot et la base sont des pièces creuses, et le capot 102 est fermé à son extrémité supérieure par une paroi 117 recouvrant le sommet, tandis que la base 104 est fermée à son extrémité inférieure par un fond 118. Avantageusement, le fond 118 comporte un orifice central 119 pour le coulage à chaud du produit cosmétique.Advantageously as illustrated in Figures 1a to 1c and figure 8c , the lower part of the cover 102 cooperates in the closed position with a hoop 103 arranged on the upper part 110 of the base 104. The cover and the base are hollow parts, and the cover 102 is closed at its upper end by a wall 117 covering the top, while the base 104 is closed at its lower end by a bottom 118. Advantageously, the bottom 118 includes a central orifice 119 for the hot pouring of the cosmetic product.

Le réceptacle 100 est destiné à recevoir un mécanisme 10 pour la distribution du produit cosmétique. Avantageusement, le mécanisme 10 est destiné à pouvoir être changé, notamment après l'utilisation complète du produit cosmétique, de manière à pouvoir continuer d'utiliser le réceptacle avec un nouveau mécanisme, ledit nouveau mécanisme formant une recharge.The receptacle 100 is intended to receive a mechanism 10 for dispensing the cosmetic product. Advantageously, the mechanism 10 is intended to be able to be changed, in particular after the complete use of the cosmetic product, so as to be able to continue to use the receptacle with a new mechanism, said new mechanism forming a refill.

Le mécanisme 10 est conçu pour contenir le produit cosmétique, et entrainer celuici depuis une position escamotée de rangement vers une position en saillie d'utilisation, par actionnement de la base 104 par un utilisateur, comme cela sera décrit plus loin. Le réceptacle est conçu pour permettre un changement du mécanisme après une utilisation complète du produit cosmétique pour y insérer une recharge pouvant être changée librement.The mechanism 10 is designed to contain the cosmetic product, and drive the latter from a retracted storage position to a projecting use position, by actuation of the base 104 by a user, as will be described later. The receptacle is designed to allow a change of the mechanism after complete use of the cosmetic product to insert therein a refill which can be changed freely.

Avantageusement une telle conception permet de conserver le capot et la base du réceptacle et d'utiliser plusieurs mécanismes comportant par exemple un bâton de rouge à lèvres avec des teintes différentes.Advantageously, such a design makes it possible to retain the cover and the base of the receptacle and to use several mechanisms comprising, for example, a stick of lipstick with different shades.

Le mécanisme 10 comporte au moins trois pièces avec une cupule 212 destinée à recevoir au moins une partie dudit produit cosmétique 11, un guide 316 et une gaine 434 qui seront détaillés ultérieurement en référence aux modes de réalisations selon l'invention. De préférence, la gaine 434, la cupule 212 et le guide 316 sont réalisés à partir d'un type de matériau métallique. Le type de matériau métallique est choisi parmi l'aluminium, des alliages d'aluminium et/ou l'acier. Avantageusement, le matériau métallique est l'aluminium anodisé.The mechanism 10 comprises at least three parts with a cup 212 intended to receive at least a part of said cosmetic product 11, a guide 316 and a sheath 434 which will be detailed later with reference to the embodiments according to the invention. Preferably, sheath 434, cup 212, and guide 316 are made from some type of metallic material. The type of metallic material is chosen from aluminium, aluminum alloys and/or steel. Advantageously, the metallic material is anodized aluminum.

Préférentiellement, le guide recouvre toute la gaine, empêchant l'entrainement en rotation de ladite gaine depuis l'un de ses rebords. Ainsi comme illustré sur la figure 8a le mécanisme ne peut être actionné que lorsqu'il est logé que dans une base spécifique présentant une configuration d'association correspondante. Pour cela, le mécanisme comprend au moins un motif d'identification configuré pour coopérer avec un moyen d'identification de la base de manière à autoriser le montage du mécanisme sur la base et permettre une entrée et/ou une sortie du produit cosmétique.Preferably, the guide covers the entire sheath, preventing said sheath from being driven in rotation from one of its edges. So as illustrated in the figure 8a the mechanism can only be operated when it is housed in a specific base having a corresponding association configuration. For this, the mechanism comprises at least one identification pattern configured to cooperate with an identification means of the base so as to authorize the assembly of the mechanism on the base and allow entry and/or exit of the cosmetic product.

Ainsi, le mécanisme d'entrée et/ou sortie du produit cosmétique ne peut être activé uniquement si la recharge est correctement associée dans la base, ceci n'étant possible que si le motif d'identification du mécanisme correspond au moyen d'identification de la base. Il pourra s'agir, par exemple, d'un positionnement angulaire spécifique. Cela permet, notamment, d'éviter une détérioration du mécanisme dans le cas d'une recharge non adaptée à la base.Thus, the mechanism for entering and/or exiting the cosmetic product can only be activated if the refill is correctly associated in the base, this being possible only if the identification pattern of the mechanism corresponds to the identification means of the base. It could be, for example, a specific angular positioning. This allows, in particular, to avoid deterioration of the mechanism in the case of a refill not adapted to the base.

La base et le capot peuvent être réalisés à partir d'un même type de matériau métallique. Ainsi selon un mode préféré de l'invention la base, le capot, la cupule, le guide et la gaine sont réalisés tous du même matériau métallique de sorte que le réceptacle peut être facilement recyclé dans la filière dédiée. De préférence, le type de matériau métallique est choisi parmi l'aluminium, des alliages d'aluminium et/ou l'acier. Avantageusement, le matériau est l'aluminium anodisé.The base and the cover can be made from the same type of metallic material. Thus, according to a preferred embodiment of the invention, the base, the cover, the cup, the guide and the sheath are all made of the same metallic material so that the receptacle can be easily recycled in the dedicated die. Preferably, the type of metallic material is chosen from aluminum, aluminum alloys and/or steel. Advantageously, the material is anodized aluminum.

Le mécanisme étant majoritairement métallique avec une gaine, une cupule et un guide en matériau métallique, il peut alors être traité dans une filière de recyclage dédié majoritairement au métal. Ainsi, Ceci permet de pourvoir réutiliser un matériau en plus grande quantité sans perte additionnelle ou rejet pour un gain optimisé. Ceci permet aussi de nettoyer et/ou recycler le mécanisme sans l'endommager par un processus de nettoyage haute température. Ainsi, le mécanisme avec la cupule, la gaine et le guide peuvent être traités ensemble sans besoin de les séparer. En variante la base, le capot, la cupule, la gaine et le guide peuvent être traités ensemble sans besoin de les séparer.Since the mechanism is mainly metallic with a sheath, a cup and a guide made of metallic material, it can then be treated in a recycling sector dedicated mainly to metal. Thus, this makes it possible to reuse a material in greater quantity without additional loss or rejection for an optimized gain. This also makes it possible to clean and/or recycle the mechanism without damaging it by a high temperature cleaning process. Thus, the mechanism with the cup, the sheath and the guide can be treated together without the need to separate them. As a variant, the base, the cap, the cup, the sheath and the guide can be treated together without the need to separate them.

Le mécanisme 10 selon les modes de réalisation illustrés sur les figures la à 8c est particulièrement destiné à recevoir un produit cosmétique présentant une formulation dite molle. Dans le cas d'un produit cosmétique présentant une telle formulation, le produit cosmétique est en contact avec tout ou partie de la paroi interne du guide 316.The mechanism 10 according to the embodiments illustrated in FIGS. 1a to 8c is particularly intended to receive a cosmetic product having a so-called soft formulation. In the case of a cosmetic product having such a formulation, the cosmetic product is in contact with all or part of the internal wall of the guide 316.

Le produit cosmétique est introduit à l'intérieur du mécanisme lors d'un procédé de coulage à chaud. L'utilisation d'un matériau métallique pour réaliser le mécanisme permet, en raison de la bonne conductivité thermique de tels matériaux, d'obtenir un refroidissement plus rapide du produit cosmétique coulé à chaud.The cosmetic product is introduced inside the mechanism during a hot casting process. The use of a metallic material to produce the mechanism makes it possible, due to the good thermal conductivity of such materials, to obtain faster cooling of the hot-poured cosmetic product.

Avantageusement, la réduction du temps de refroidissement permet de réduire la durée du cycle de fabrication et d'améliorer l'aspect du produit cosmétique, l'aspect étant notamment plus lisse.Advantageously, the reduction in the cooling time makes it possible to reduce the duration of the manufacturing cycle and to improve the appearance of the cosmetic product, the appearance being in particular smoother.

Préférentiellement, la partie 114 inférieure de la base 104 comporte intérieurement des moyens de rétention afin de prévenir un arrachement, c'est-à-dire un déplacement vertical, dudit mécanisme par rapport à la base. Il pourra s'agir, par exemple, d'un système de harpons 108 comme illustrée sur les figures 8a et 8c.Preferably, the lower part 114 of the base 104 internally comprises retention means in order to prevent tearing, that is to say a vertical displacement, of said mechanism relative to the base. It could be, for example, a system of harpoons 108 as illustrated on the figure 8a and 8c .

Par ailleurs, la partie 114 inférieure de la base 104 comporte des moyens d'anti-rotation 120, de sorte que tout mouvement de rotation autour de l'axe Y appliqué par l'utilisateur sur la partie 114 inférieure de la base 104 est directement transmis au mécanisme 10. Pour ces moyens d'anti-rotation, il pourra s'agir, par exemple, d'un système de type engrenage tel que représenté sur la figure 7a et/ou d'un godron positionné sur une surface du mécanisme comme représenté sur les figures 7b, 8a à 8b.Furthermore, the lower part 114 of the base 104 comprises anti-rotation means 120, so that any rotational movement around the Y axis applied by the user to the lower part 114 of the base 104 is directly forwarded to mechanism 10. For these anti-rotation means, it could be, for example, a gear-type system as represented on the figure 7a and/or a gadroon positioned on a surface of the mechanism as shown in the figure 7b , 8a to 8b .

De préférence, le fond 118 de la base 104 est configuré pour être relié à une pièce d'interface 538 et la pièce d'interface 538 permet l'attache du mécanisme sur la base.Preferably, the bottom 118 of the base 104 is configured to be connected to an interface part 538 and the interface part 538 allows the mechanism to be attached to the base.

Avantageusement, la pièce d'interface fait partie de la base comme illustrée sur les figures 8a et 8b. La pièce d'interface comprend un corps cylindrique 511 creux s'étendant axialement et délimité par un bord 513 supérieur et par un bord 515 inférieur. Ledit bord 515 inférieur du corps cylindrique 511 formant une ouverture 514, dite ouverture de la pièce d'interface.Advantageously, the interface part forms part of the base as illustrated in the figures 8a and 8b . The interface part comprises a hollow cylindrical body 511 extending axially and delimited by an upper edge 513 and by a lower edge 515. Said lower edge 515 of the cylindrical body 511 forming an opening 514, called the opening of the interface part.

Avantageusement, la pièce d'interface 538 est en aluminium. Selon un mode de réalisation de l'invention, ledit bord inférieur 515 de la pièce d'interface 538 est configuré pour être positionné à travers une ouverture 119 formée au niveau du fond 118 de la base, puis retenu par bouterollage contre une projection 151 entourant ladite ouverture 150.Advantageously, the interface part 538 is made of aluminum. According to one embodiment of the invention, said lower edge 515 of the interface piece 538 is configured to be positioned through an opening 119 formed at the level of the bottom 118 of the base, then retained by riveting against a projection 151 surrounding said opening 150.

Par bouterollage, on entend une opération de pliage du bord inférieur 515 de la pièce d'interface 538 contre la projection 151 formée au niveau du fond 118. Ce pliage permet d'établir un contact paroi contre paroi entre ledit bord inférieur 515 et la projection 151 pour fixer solidement la pièce d'interface 538 sur de la base 104. La mise en œuvre de ce pliage est rendue possible ici grâce à la forme évasée du bord inférieur 515, et une forme complémentaire de la projection 151 comme illustrée sur les figures 8a et 8b. En outre, la mise en œuvre de ce pliage conduit notamment à aligner l'ouverture 514 de la pièce d'interface avec l'ouverture 150 de la du fond 118 de la base 104 comme représenté sur les figures 8a et 8b. Le terme bouterollage peut être entendu également comme un sertissage de la pièce d'interface dans le fond 118 de la base 104.By riveting is meant an operation of bending the lower edge 515 of the interface piece 538 against the projection 151 formed at the level of the bottom 118. This bending makes it possible to establish wall-to-wall contact between said lower edge 515 and the projection 151 to firmly fix the interface part 538 on the base 104. The implementation of this folding is made possible here thanks to the flared shape of the lower edge 515, and a complementary shape of the projection 151 as illustrated on the figures 8a and 8b . In addition, the implementation of this folding results in particular in aligning the opening 514 of the interface part with the opening 150 of the bottom 118 of the base 104 as shown in the figures 8a and 8b . The term riveting can also be understood as a crimping of the interface part in the bottom 118 of the base 104.

Avantageusement, comme illustré sur la figure 8a lesdits harpons 108 sont des découpes agencées sur le corps cylindrique 511 et apte se positionner en assise sur un bord périphérique interne de la pièce d'interface, par exemple une gorge externe, de sorte à bloquer axialement le mécanisme par rapport à la base. Dans l'exemple, les moyens 120 d'engrenage sont en outre formés par des godrons 122 faisant saillies par rapport au corps cylindrique 511 et aptes à se positionner dans des fentes 450 disposées sur une paroi du mécanisme 10, les fentes 450 seront décrites plus loin.Advantageously, as illustrated in figure 8a said harpoons 108 are cutouts arranged on the cylindrical body 511 and capable of being positioned seated on an internal peripheral edge of the interface part, for example an external groove, so as to block the mechanism axially with respect to the base. In the example, the gear means 120 are also formed by gadroons 122 projecting from the cylindrical body 511 and capable of being positioned in slots 450 arranged on a wall of the mechanism 10, the slots 450 will be described further. far.

En variante non représentée, la pièce d'interface 538 en aluminium est issue de matière de la base en aluminium.In a variant not shown, the aluminum interface part 538 comes from the material of the aluminum base.

En variante, la pièce d'interface 538 fait partie du mécanisme 10 comme illustrée sur les figures 7a à 7c et 8c. Ainsi, pour s'adapter à différentes configurations de base, le mécanisme est maintenu à la base par une pièce d'interface 538. La pièce d'interface 538 est agencée sous la forme d'une pièce tubulaire comprenant axialement une partie supérieure 545 avec une enveloppe 551, dite première enveloppe, qui présente une paroi latérale 551a ainsi qu'un bord supérieur 551b configuré pour coopérer avec des harpons 108 de la base pour prévenir un arrachement, c'est-à-dire un déplacement vertical, dudit mécanisme 10 par rapport à la base 104.Alternatively, the interface piece 538 forms part of the mechanism 10 as illustrated in the figures 7a to 7c and 8c . Thus, to adapt to different base configurations, the mechanism is held at the base by an interface part 538. The interface part 538 is arranged in the form of a tubular part comprising axially an upper part 545 with an envelope 551, called the first envelope, which has a side wall 551a as well as an upper edge 551b configured to cooperate with harpoons 108 of the base to prevent tearing, that is to say vertical displacement, of said mechanism 10 relative to base 104.

Ainsi, le fond 118 de la base 104 comprend trois pattes flexibles dont l'extrémité libre est configurée pour former un crochet 70 sous la forme de harpons. Lesdits harpons espacés de 120° viennent coopérer avec le bord supérieur 551b de la pièce d'interface 538 et servent de moyens de fixation pour lier axialement la base 104 audit mécanisme 10.Thus, the bottom 118 of the base 104 comprises three flexible legs whose free end is configured to form a hook 70 in the form of harpoons. Said harpoons spaced by 120° come to cooperate with the upper edge 551b of the interface part 538 and serve as fastening means for axially linking the base 104 to said mechanism 10.

Par ailleurs, la partie inférieure 555 avec une enveloppe 552, dite seconde enveloppe, présente une paroi latérale 552a ainsi qu'un bord inférieur 552b configurés pour recevoir des stries 560 de destinées à coopérer avec les cannelures 122 de la base 104 de l'étui 100. Dans l'exemple, les stries 560 de la pièce d'interface 538 et les cannelures 122 de la base 104 ont des formes complémentaires et constituent lesdits moyens 120 d'engrenage. Grace aux moyens 120 d'engrenage, tout mouvement de rotation autour de l'axe Y qui est appliqué par une utilisatrice sur la partie 114 inférieure de la base 104 est transmis au mécanisme 10, par l'intermédiaire de la pièce d'interface 538.Furthermore, the lower part 555 with an envelope 552, called the second envelope, has a side wall 552a as well as a lower edge 552b configured to receive ridges 560 of intended to cooperate with the grooves 122 of the base 104 of the case 100. In the example, the ridges 560 of the interface part 538 and the splines 122 of the base 104 have complementary shapes and constitute said gear means 120. Thanks to the gear means 120, any rotational movement around the Y axis which is applied by a user to the lower part 114 of the base 104 is transmitted to the mechanism 10, via the interface part 538 .

Avantageusement, la pièce d'interface 538 comporte deux godrons 580 qui s'étendent radialement depuis la première enveloppe 551 et la deuxième enveloppe 552, et sont agencées préférentiellement de manière diamétralement opposée dans un même plan. Les deux godrons 580 sont destinées à s'emboiter dans deux fentes 450 de la gaine 434, qui sera décrite ultérieurement, pour bloquer ladite gaine 434 en rotation par rapport à la base 104. Lesdits godrons 580 et lesdites fentes 450 formant ainsi un système anti-rotation.Advantageously, the interface part 538 comprises two gadroons 580 which extend radially from the first casing 551 and the second casing 552, and are preferably arranged in a diametrically opposite manner in the same plane. The two gadroons 580 are intended to fit into two slots 450 of the sheath 434, which will be described later, to block said sheath 434 in rotation relative to the base 104. Said gadroons 580 and said slots 450 thus forming an anti -spin.

Aussi les bords 522b et 521b ont des ouvertures permettant le passage du produit cosmétique lors du procédé de coulage à chaud. La jonction entre la partie supérieure 545 et la partie inférieure 555 présente un épaulement 565 formant une assise de réception de la cupule 212, qui sera décrite ultérieurement, de sorte à bloquer en butée le déplacement vers le bas de la cupule 212. La pièce d'interface 538 comprend une nervure déformable périphérique 580 agencée sur la seconde enveloppe 552 et destinée à être en contact avec la paroi de la partie inférieure du corps 320 du guide 316. Le guide 316 sera décrit ultérieurement. Un tel contact permet de contrôler le couple de fonctionnement entre la pièce d'interface 538 et le guide 316.Also the edges 522b and 521b have openings allowing the passage of the cosmetic product during the hot casting process. The junction between the upper part 545 and the lower part 555 has a shoulder 565 forming a base for receiving the cup 212, which will be described later, so as to block the downward movement of the cup 212 in abutment. interface 538 comprises a peripheral deformable rib 580 arranged on the second casing 552 and intended to be in contact with the wall of the lower part of the body 320 of the guide 316. The guide 316 will be described later. Such a contact makes it possible to control the operating torque between the interface part 538 and the guide 316.

De préférence, la pièce d'interface 538 peut être fait de tout matériau synthétique, par exemple, un élastomère thermoplastique (TPE), polyéthylène basse densité (LDPE), polymère synthétique, polypropylène (PP), polyéthylène (PE), matériau composite, polyéthylène téréphtalate (PET), recyclé post-consommation (PCR), polyéthylène haute densité (HDPE) et / ou analogues. En particulier, le matériau synthétique peut être choisi parmi des matériaux fluoro-élastomères (FKM) résistant au processus de nettoyage haute température supérieur à 150°C.Preferably, the interface piece 538 can be made of any synthetic material, for example, a thermoplastic elastomer (TPE), low density polyethylene (LDPE), synthetic polymer, polypropylene (PP), polyethylene (PE), composite material, polyethylene terephthalate (PET), post-consumer recycled (PCR), high density polyethylene (HDPE) and/or the like. In particular, the synthetic material can be chosen from fluoroelastomer materials (FKM) resistant to the high temperature cleaning process above 150°C.

En outre, ces portions inférieure 124 et supérieure 125 sont configurées pour exercer une pression radiale respectivement contre la partie supérieure 110 de la base et la paroi externe du mécanisme. Ainsi cet agencement permet de positionner la partie supérieure 110 de la base par rapport au mécanisme.With reference to the figure 8a , hoop 103 of base 104 comprises a lower portion 124, an upper portion 125, as well as an intermediate portion 126 connecting said lower portion 124 and said upper portion 125. In addition, these lower 124 and upper 125 portions are configured to exert a radial pressure respectively against the upper part 110 of the base and the external wall of the mechanism. Thus this arrangement makes it possible to position the upper part 110 of the base relative to the mechanism.

La portion intermédiaire 126 de la frette 103 forme une collerette ayant un diamètre sensiblement égal à un diamètre extérieur de la base 104. Avantageusement, la portion intermédiaire 126 présente un épaulement 129 formant une assise de réception du capot 102 et assure le maintien axial du capot 102 sur la base 104 en position de fermeture.The intermediate portion 126 of the hoop 103 forms a flange having a diameter substantially equal to an outer diameter of the base 104. Advantageously, the intermediate portion 126 has a shoulder 129 forming a base for receiving the cowl 102 and ensures the axial retention of the cowl 102 on the base 104 in the closed position.

Alternatively shown in figure 6c , the cup comprises screwing-unscrewing means in the form of threads 228, having an internal groove profile.

Le nombre de tétons, de filets ou bien leur largeur permet plus de stabilité pour gérer le couple de fonctionnement lors du vissage ou dévissage de la rainure hélicoïdale de la gaine 434.The number of nipples, threads or their width allows more stability to manage the operating torque when screwing or unscrewing the helical groove of the sheath 434.

En variante non représentée, la cupule 212 est réalisée en deux parties respectivement une cupule supérieure destinée à recevoir le produit cosmétique et une cupule inférieure. La cupule inférieure comporte alors lesdits moyens de visage-dévissage destinés à coopérer avec la gaine 434.In a variant not shown, the cup 212 is made in two parts respectively an upper cup intended to receive the cosmetic product and a lower cup. The lower cup then comprises said face-unscrewing means intended to cooperate with the sheath 434.

La cupule 212 comporte des moyens de fixation du raisin au voisinage du bord 213a. Tel qu'illustrée par les figures 4a à 4d et 8a, ladite cupule comprend des moyens de fixation du raisin 215, par exemple des trous 215a, des pattes de fixation 215b orientées sensiblement radialement vers l'intérieur et/ou une gorge interne 215c sur sa paroi latérale 211, pour permettre de lier le raisin à la cupule 212. Avantageusement, la gorge interne 215c est réalisée par déformation de surface radialement vers l'intérieur et s'étend circonférentiellement, en formant un cercle concentrique autour de l'axe de révolution de la cupule 212.The cup 212 comprises means for fixing the grape in the vicinity of the edge 213a. As illustrated by the figures 4a to 4d and 8a , said cup comprises means for fixing the stick 215, for example holes 215a, fixing lugs 215b oriented substantially radially inwards and/or an internal groove 215c on its side wall 211, to make it possible to bind the stick to the cup 212. Advantageously, the internal groove 215c is produced by surface deformation radially inwards and extends circumferentially, forming a concentric circle around the axis of revolution of the cup 212.

La cupule 212 est réalisée comme illustrée sur les figures 4a à 4d, 5a et 8a à 8c, en seule une pièce et comprend respectivement une portion supérieure de cupule 212a destinée à recevoir le produit cosmétique et une portion inférieure de cupule 212b entourant la gaine 434.

Selon un mode de réalisation de l'invention la cupule 212 comprend deux pattes flexibles 270 reliées à la cupule 212 depuis leur partie supérieure 276, tandis que leur extrémité inférieure 277 est libre permettant un déplacement radial. L'extrémité 277 libre de la patte flexible 270 présente au moins une déformation de surface sous la forme d'un ergot 275 avec un profil de section globalement cylindrique permettant l'emboitement dans lesdites glissières verticales 332 du guide 316.According to one embodiment of the invention, the cup 212 comprises two flexible tabs 270 connected to the cup 212 from their upper part 276, while their lower end 277 is free allowing radial displacement. The free end 277 of the flexible lug 270 has at least one surface deformation in the form of a lug 275 with a generally cylindrical cross-section profile allowing fitting into said vertical slideways 332 of the guide 316.

Dans l'exemple, l'ergot 275 est obtenu par emboutissage. La largeur de l'ergot 275 est dimensionnée pour correspondre sensiblement à la largeur de ladite glissière verticale 332 de sorte à bloquer en rotation la cupule 212 du guide 316. Ainsi, le guide est solidaire en rotation de la cupule. Lors de l'assemblage de la cupule 212 avec le guide 216, les deux pattes flexibles 270 se déplacent radialement vers l'intérieur, puis rappelées élastiquement radialement vers l'extérieur dans une phase finale d'assemblage, pour venir chacune se loger automatiquement dans au moins l'une des glissières du guide 316.In the example, the lug 275 is obtained by stamping. The width of the lug 275 is sized to correspond substantially to the width of said vertical slide 332 so as to block the cup 212 of the guide 316 in rotation. Thus, the guide is integral in rotation with the cup. During the assembly of the cup 212 with the guide 216, the two flexible tabs 270 move radially inwards, then elastically returned radially outwards in a final assembly phase, each to come and lodge automatically in at least one of the guide rails 316.

Les deux pattes flexibles 270 s'étendant suivant une direction axiale, sont obtenues selon une découpe rectiligne de largeur « I » prédéterminée et sont espacées d'une distance « e » constante sur leur longueur du corps externe cylindrique 252 de la cupule 212. Avantageusement, la forme des deux pattes flexibles 270 s'étendant suivant une direction axiale, est obtenue selon une découpe constituant un espacement « e » variable au corps externe cylindrique 252. Telles qu'illustrées sur la figure 5b les pattes flexibles ont une largeur plus importante à leur partie supérieure 276 qu'à leur extrémité 277. La forme de la base des pattes flexibles permet un contact en surface plus important avec le guide et augmente la raideur des pattes pour une meilleure stabilité lors de l'actionnement du mécanisme. Ainsi, cet aspect permet d'obtenir des effets de fonctionnement satisfaisants pour les utilisateurs. Avantageusement, la cupule 212 est formée d'une seule pièce en aluminium obtenue par usinage, par exemple par emboutissage.The two flexible tabs 270 extending in an axial direction, are obtained according to a rectilinear cutout of predetermined width “I” and are spaced apart by a constant distance “e” along their length from the cylindrical outer body 252 of the cup 212. Advantageously , the shape of the two flexible tabs 270 extending in an axial direction, is obtained according to a cutout constituting a variable spacing "e" to the cylindrical outer body 252. As illustrated in the figure 5b the flexible legs have a greater width at their upper part 276 than at their end 277. The shape of the base of the flexible legs allows greater surface contact with the guide and increases the stiffness of the legs for better stability during the actuation of the mechanism. Thus, this aspect achieves satisfactory operation effects for users. Advantageously, the cup 212 is formed from a single piece of aluminum obtained by machining, for example by stamping.

Le guide 316 comprend un corps cylindrique creux et comporte principalement une partie supérieure, qui sera désignée ci-après comme étant une tête 318, et prolonge axialement une partie inférieure, qui sera désignée ci-après comme étant un corps 320. La tête 318 du guide 316 présente une paroi interne 318a lisse assurant un support latéral pour le guidage du raisin, et le corps 320 du guide 316 assurant le guidage de la cupule selon un mouvement de translation axiale lors de l'actionnement du mécanisme.The guide 316 comprises a hollow cylindrical body and mainly comprises an upper part, which will be designated hereinafter as being a head 318, and axially extends a lower part, which will be designated hereinafter as being a body 320. The head 318 of the guide 316 has a smooth inner wall 318a providing lateral support for guiding the grapes, and the body 320 of the guide 316 ensuring the guidance of the cup according to an axial translational movement when the mechanism is actuated.

Selon le mode de réalisation de l'invention, le corps 320 du guide 316 comprend deux glissières verticales 332 agencées de manière diamétralement opposée et configurées pour recevoir en coulissement les ergots 275 de la cupule 212. La cupule 212 étant montée mobile axialement à l'intérieur du guide 316 et chaque glissière 332 présente des extrémités 278, 279 formant butées de fin de course de l'ergot 275 du guide 316. La distance entre les extrémités 278 et 279, définissant une course de déplacement de la cupule 212 dans le mécanisme 10.According to the embodiment of the invention, the body 320 of the guide 316 comprises two vertical slideways 332 arranged in a diametrically opposite manner and configured to receive the lugs 275 of the cup 212 in sliding motion. The cup 212 being movably mounted axially at the interior of the guide 316 and each slide 332 has ends 278, 279 forming end stops of the lug 275 of the guide 316. The distance between the ends 278 and 279, defining a displacement travel of the cup 212 in the 10.

Préférentiellement, le guide et la gaine sont à la fois liés solidairement axialement, et libres en rotation l'un par rapport à l'autre. Ainsi dans le bas du mécanisme, le corps 320 du guide 316 comprend une gorge externe 322 positionnée en regard d'une gorge 422 de la gaine, afin d'empêcher un déplacement axial de la gaine 434 par rapport au guide tout en laissant libre la rotation de la gaine 434 dans le guide 316. Avantageusement, la gorge externe 322 du guide et la gorge 422 de la gaine sont obtenues par déformation latérale de leur paroi, par exemple par emboutissage.Preferably, the guide and the sheath are both integrally linked axially, and free in rotation with respect to each other. Thus at the bottom of the mechanism, the body 320 of the guide 316 comprises an external groove 322 positioned opposite a groove 422 of the sheath, in order to prevent an axial displacement of the sheath 434 relative to the guide while leaving free the rotation of the sheath 434 in the guide 316. Advantageously, the outer groove 322 of the guide and the groove 422 of the sheath are obtained by lateral deformation of their wall, for example by stamping.

De préférence, un joint annulaire 460, 490 est disposé entre le guide et la gaine afin de contrôler le couple de rotation entre la gaine 434 et le guide 316.Preferably, an annular seal 460, 490 is disposed between the guide and the sheath in order to control the rotational torque between the sheath 434 and the guide 316.

Selon un mode de réalisation, illustré à la figure 3a, un premier joint annulaire 460 est disposé dans un logement formé entre ladite gorge externe 322 du guide et ladite gorge 422 de la gaine. Avantageusement, le premier joint annulaire 460 dans cette disposition permet à la fois d'immobiliser axialement la gaine 434 par rapport au guide tout en laissant libre la rotation de la gaine dans le guide, et également de contrôler le couple de rotation entre la gaine 434 et le guide 316.According to one embodiment, illustrated in picture 3a , a first annular seal 460 is disposed in a housing formed between said outer groove 322 of the guide and said groove 422 of the sheath. Advantageously, the first annular joint 460 in this arrangement makes it possible both to immobilize the sheath 434 axially with respect to the guide while leaving the sheath free to rotate in the guide, and also to control the torque between the sheath 434 and Guide 316.

Selon un mode de réalisation de l'invention, illustré à la figure 3b, la gorge externe 322 est positionnée en butée contre la gorge 422 de la gaine qui a la même géométrie ainsi qu'une même orientation radiale que ladite gorge externe 322. Avantageusement cet agencement permet d'immobiliser axialement la gaine 434 par rapport au guide 316 tout en laissant libre la rotation de la gaine 434 dans le guide 316. Avantageusement, un second joint annulaire 490 est positionné entre une seconde gorge 423 agencée sur la gaine et la paroi intérieure du guide afin de contrôler le couple de rotation entre la gaine 434 et le guide 316.According to one embodiment of the invention, illustrated in figure 3b , the external groove 322 is positioned in abutment against the groove 422 of the sheath which has the same geometry as well as the same radial orientation as said external groove 322. Advantageously, this arrangement makes it possible to immobilize the sheath 434 axially with respect to the guide 316 while leaving free the rotation of the sheath 434 in the guide 316. Advantageously, a second annular seal 490 is positioned between a second groove 423 arranged on the sheath and the inner wall of the guide in order to control the torque between the sheath 434 and Guide 316.

Le guide 316 comporte un bord 348 supérieur, ici de forme biseautée et, axialement à l'opposé, un bord 350 inférieur de forme circulaire. Selon le mode de réalisation illustré sur les figures la à 8c, les profils de la cupule et du guide sont cylindriques. Le mécanisme selon l'invention, permet pour le mécanisme 10 soit guidé et que le profil extérieur de la cupule et le profil du guide ne soient pas forcément cylindriques.The guide 316 comprises an upper edge 348, here of beveled shape and, axially opposite, a lower edge 350 of circular shape. According to the embodiment illustrated in FIGS. 1a to 8c, the profiles of the cup and of the guide are cylindrical. The mechanism according to the invention allows the mechanism 10 to be guided and the outer profile of the cup and the profile of the guide are not necessarily cylindrical.

La gaine 434 comprend un corps cylindrique creux, comportant au moins une rainure 442 hélicoïdale agencée dans sa paroi 444 externe. De préférence, Le guide 316 est agencé autour de la gaine 434. La gaine 434 est montée à l'intérieur du corps 320 du guide 316.The sheath 434 comprises a hollow cylindrical body, comprising at least one helical groove 442 arranged in its outer wall 444. Preferably, guide 316 is arranged around sheath 434. Sheath 434 is mounted inside body 320 of guide 316.

Selon le mode de réalisation illustré en figure 2c, la gaine 434 comporte une rainure 442 hélicoïdale qui est destinée à coopérer avec au moins l'un des tétons 214 de la cupule 212. L'actionnement du mécanisme par l'entrainement en rotation de la gaine 434 provoque alors un déplacement axial en translation de la cupule 212 qui est ainsi mise en déplacement. Ainsi, La gaine 434 comportant à son extrémité inférieure 430 deux fentes 450 agencées axialement et de manière diamétralement opposée. Les deux fentes 450 permettent une déformation radiale de l'extrémité inférieure 430 vers l'intérieur, lors de l'assemblage de la gaine 434 avec le guide 316 pour faciliter l'emboitement.According to the embodiment illustrated in figure 2c , the sheath 434 has a helical groove 442 which is intended to cooperate with at least one of the studs 214 of the cup 212. The actuation of the mechanism by the rotational drive of the sheath 434 then causes an axial displacement in translation of the cup 212 which is thus moved. Thus, the sheath 434 comprising at its lower end 430 two slots 450 arranged axially and diametrically opposite. The two slots 450 allow radial deformation of the lower end 430 inwards, during assembly of the sheath 434 with the guide 316 to facilitate fitting.

De préférence, les deux fentes 450 axiales sont destinées à s'emboiter directement une pièce d'interface 538, pour bloquer ladite gaine 434 en rotation par rapport à la base 20. Les deux godrons 580 de la pièce d'interface sont destinés à s'emboiter dans deux fentes 450 de la gaine 434. Lesdits godrons 580 et lesdites fentes 450 formant ainsi un système anti-rotation.Preferably, the two axial slots 450 are intended to fit directly into an interface piece 538, to block said sheath 434 in rotation relative to the base 20. The two gadroons 580 of the interface piece are intended to be fit into two slots 450 of the sheath 434. Said gadroons 580 and said slots 450 thus forming an anti-rotation system.

De préférence, la gaine 434 comprend à son extrémité inférieure 430 au moins un moyen d'accroche 433, ledit moyen d'accroche étant apte à fixer de manière amovible la gaine à une base. Ainsi, le moyen d'accroche 433 de la gaine est destiné à s'emboiter dans un logement 25 de la base 20. Selon le mode de réalisation illustré en figure 2c, la gaine comprend deux moyens d'accroche 433 agencés à l'extrémité inférieure de la gaine 434 et de manière diamétralement opposée. Ces deux moyens d'accroche 433 sont projections latérales avec en section un profil circulaire obtenu par déformation de surface et orientées vers l'intérieur du mécanisme destinés à coopérer en butée avec une forme complémentaire desdits moyens d'accroche 433.Preferably, the sheath 434 comprises at its lower end 430 at least one hooking means 433, said hooking means being able to removably fix the sheath to a base. Thus, the attachment means 433 of the sheath is intended to fit into a housing 25 of the base 20. According to the embodiment illustrated in figure 2c , the sheath comprises two attachment means 433 arranged at the lower end of the sheath 434 and diametrically opposite. These two attachment means 433 are lateral projections with a circular profile in section obtained by surface deformation and oriented towards the inside of the mechanism intended to cooperate in abutment with a complementary shape of said attachment means 433.

Dans une formulation de raisin dite molle, lors de sa formation le raisin est coulé à chaud à l'intérieur du mécanisme, puis prend sa forme externe au contact des parois latérales internes du mécanisme, en particulier avec la tête 318 du guide 316 et la paroi interne de la gaine. Le raisin subit un retrait de matière lors du refroidissement et prend ensuite sa forme définitive. Le raisin, comme illustré sur la figure 9b, comprend une portion supérieure 710 destinée à être consommée lors de l'application par l'utilisateur, une portion inférieure 720 restant à demeure l'intérieur du mécanisme et permettant un soutènement du raisin. Ledit raisin comprend également une portion intermédiaire 715 fixée par les moyens de fixation 215b sur la cupule, ladite portion intermédiaire reliant ladite portion inférieure 720 et ladite portion supérieure 710.In a so-called soft stick formulation, during its formation the stick is hot poured inside the mechanism, then takes its external shape in contact with the inner side walls of the mechanism, in particular with the head 318 of the guide 316 and the inner sheath wall. The grape undergoes a shrinkage of material during cooling and then takes its final shape. The grape, as illustrated in the figure 9b , comprises an upper portion 710 intended to be consumed during application by the user, a lower portion 720 remaining permanently inside the mechanism and allowing the grapes to be supported. Said grape also comprises an intermediate portion 715 fixed by the fixing means 215b on the cup, said intermediate portion connecting said lower portion 720 and said upper portion 710.

La paroi interne de la tête 318 du guide 316 présente une surface de contact lisse. On entend par surface de contact lisse, une surface ne présentant pas de trous, ni localement de parties concaves ou convexes pouvant endommager le raisin, en particulier lors de sa formation et/ou de son déplacement vertical dans le mécanisme. Par conséquent, la portion supérieure 710 du raisin n'interfère pas avec la tête 318 du guide 316.The internal wall of the head 318 of the guide 316 has a smooth contact surface. The term "smooth contact surface" means a surface having no holes, nor locally any concave or convex parts which could damage the stick, in particular during its formation and/or its vertical displacement in the mechanism. Therefore, the upper portion 710 of the grape does not interfere with the head 318 of the guide 316.

De préférence, un tube d'interface 750 est agencé à l'intérieur de la gaine 434. Le tube d'interface 750 comprend un corps cylindrique creux 760 et une paroi interne 770 avec une surface de contact lisse.Preferably, an interface tube 750 is arranged inside the sheath 434. The interface tube 750 includes a hollow cylindrical body 760 and an inner wall 770 with a smooth contact surface.

Avantageusement, ledit tube d'interface est disposé à l'intérieur de la gaine, comme illustré sur les figures 9a et 9b, ledit tube d'interface étant solidaire de la cupule et apte à s'interfacer entre ladite gaine et le raisin, lors du déplacement vertical de ladite cupule. Par conséquent lors de sa formation, la portion inférieure du raisin vient en appui sur la paroi interne 770 du tube d'interface 750 et n'est pas en contact directement avec la paroi interne 490 de la gaine 434. Ainsi, la portion inférieure 720 du raisin, n'interfère pas avec les autres pièces du mécanisme lors du déplacement axial de la cupule 212. Ledit tube d'interface 750 est calé en butée respectivement entre les pattes de fixation 215c et le bord supérieur de la pièce d'interface 551b.Advantageously, said interface tube is arranged inside the sheath, as illustrated in the figure 9a and 9b , said interface tube being secured to the cup and capable of interfacing between said sheath and the stick, during the vertical displacement of said cup. Consequently, during its formation, the lower portion of the stick bears against the internal wall 770 of the interface tube 750 and is not in direct contact with the internal wall 490 of the sheath 434. Thus, the lower portion 720 of the grape, does not interfere with the other parts of the mechanism during the axial displacement of the cup 212. Said interface tube 750 is wedged in abutment respectively between the fixing lugs 215c and the upper edge of the interface part 551b .

De préférence, le tube d'interface 750 est en matériau métallique de sorte que le réceptacle peut être facilement recyclé dans la filière dédiée. De préférence, le type de matériau métallique est choisi parmi l'aluminium, des alliages d'aluminium et/ou l'acier. Avantageusement, le matériau est l'aluminium anodisé.Preferably, the interface tube 750 is made of metallic material so that the receptacle can be easily recycled in the dedicated sector. Preferably, the type of metallic material is chosen from aluminum, aluminum alloys and/or steel. Advantageously, the material is anodized aluminum.

En variante, le tube d'interface 750 peut être fait de tout matériau synthétique ou fait en papier. Par exemple, un élastomère thermoplastique (TPE), polyéthylène basse densité (LDPE), polymère synthétique, polypropylène (PP), polyéthylène (PE), matériau composite, polyéthylène téréphtalate (PET), recyclé post-consommation (PCR), polyéthylène haute densité (HDPE) et / ou analogues. En particulier, le matériau synthétique peut être choisi parmi des matériaux fluoro-élastomères (FKM) résistant au processus de nettoyage haute température supérieur à 150°C.Alternatively, interface tube 750 can be made of any synthetic material or made of paper. For example, thermoplastic elastomer (TPE), low density polyethylene (LDPE), synthetic polymer, polypropylene (PP), polyethylene (PE), composite material, polyethylene terephthalate (PET), post-consumer recycled (PCR), high density polyethylene (HDPE) and/or the like. In particular, the synthetic material can be chosen from fluoroelastomer materials (FKM) resistant to the high temperature cleaning process above 150°C.

De préférence, au moins un anneau élastique 610 est inséré entre la cupule et le guide, ledit anneau élastique étant apte à contrôler le couple de fonctionnement entre le guide et la cupule. Ainsi pour améliorer la stabilité du couple de fonctionnement lors de l'actionnement du mécanisme pour la montée-descente du produit cosmétique, un anneau élastique 610 est partiellement logé dans au moins la gorge interne 216 de la paroi latérale 211 de la cupule 212.Preferably, at least one elastic ring 610 is inserted between the cup and the guide, said elastic ring being able to control the operating torque between the guide and the cup. Thus, to improve the stability of the operating torque when the mechanism for raising/lowering the cosmetic product is actuated, an elastic ring 610 is partially housed in at least the internal groove 216 of the side wall 211 of the cup 212.

Avantageusement la même gorge interne 216 permet d'une part le maintien du raisin sur sa partie interne 217 et d'autre part, le maintien d'un anneau élastique sur sa partie externe 218, permettant de contrôler le couple de fonctionnent. Cet anneau élastique, en contact de la paroi interne de la tête 318 du guide 316 comme illustrée dans la figure 3c, permet de contrôler le déplacement relatif de la cupule 212 par rapport au guide 316. En d'autres termes, lors du déplacement de la cupule 212, la zone de contact entre l'anneau élastique 610 et la paroi interne de la tête 318 du guide 316 permet un contrôle précis de la force de frottement. Ainsi cet anneau élastique permet d'éviter que la quantité de déplacement du bâton de rouge à lèvres soit trop importante par rapport au souhait de l'utilisateur. Cet anneau élastique permet également d'éviter des problèmes de sonorité pouvant être désagréables pour l'utilisateur, dus aux frottements entre des pièces en aluminium, à savoir en particulier le guide et la cupule.Advantageously, the same internal groove 216 makes it possible, on the one hand, to hold the stick on its internal part 217 and, on the other hand, to hold an elastic ring on its external part 218, making it possible to control the operating torque. This elastic ring, in contact with the internal wall of the head 318 of the guide 316 as illustrated in the figure 3c , makes it possible to control the relative displacement of the cup 212 with respect to the guide 316. in other words, during the movement of the cup 212, the contact zone between the elastic ring 610 and the internal wall of the head 318 of the guide 316 allows precise control of the friction force. Thus, this elastic ring makes it possible to prevent the amount of movement of the stick of lipstick from being too great in relation to the wishes of the user. This elastic ring also makes it possible to avoid sound problems which may be unpleasant for the user, due to friction between aluminum parts, namely in particular the guide and the cup.

De préférence l'anneau élastique 610 est un joint qui peut être fait de tout matériau synthétique, par exemple, en caoutchouc ou être réalisé en d'autres matériaux élastomères appropriés tels que le polypropylène (PP) ou le polyéthylène (PE). Ce joint étant en masse très faible par rapport au mécanisme 10, il sera éliminé par combustion lors du processus de recyclage approprié. Cependant il peut avantageusement également être choisi parmi des matériaux fluoro-élastomères (FKM) résistant à la température. De sorte à obtenir un mécanisme pour un nouvel usage, le mécanisme avantageusement en matériau aluminium peut être recueilli et nettoyé avec un processus approprié de nettoyage haute température, en particulier supérieur à 150°C.Preferably the elastic ring 610 is a joint which can be made of any synthetic material, for example rubber, or be made of other suitable elastomeric materials such as polypropylene (PP) or polyethylene (PE). This seal being very low in mass compared to the mechanism 10, it will be eliminated by combustion during the appropriate recycling process. However, it can advantageously also be chosen from temperature-resistant fluoroelastomer materials (FKM). So as to obtain a mechanism for a new use, the mechanism advantageously made of aluminum material can be collected and cleaned with an appropriate high temperature cleaning process, in particular above 150°C.
