Description

Dispositif de distribution et d'application d'un produit cosmétique ou de soin  Device for dispensing and applying a cosmetic or care product
L'invention concerne le domaine des dispositifs de distribution et d'application d'un produit cosmétique ou de soin. The invention relates to the field of devices for dispensing and applying a cosmetic or care product.
Les produits cosmétiques englobent tous les produits pour le maquillage de la peau ou des phanères ainsi que toutes les compositions parfumantes ou odorantes destinées à une application corporelle.  Cosmetic products include all the products for the make-up of the skin or superficial body growths as well as all the fragrant or odorous compositions intended for body application.
Les produits de soin comportent notamment ceux destinés à être appliqués sur le corps humain ou animal pour traiter ou prévenir une pathologie.  The care products include those intended to be applied to the human or animal body to treat or prevent a pathology.
L'invention porte en particulier sur un dispositif de distribution et d'application d'un tel produit cosmétique ou de soin se présentant sous forme liquide, semi-fluide ou pâteuse. The invention relates in particular to a device for dispensing and applying such a cosmetic or care product in liquid, semi-fluid or pasty form.
Des dispositifs permettant la distribution et l'application d'un produit cosmétique sont connus dans l'état de la technique selon diverses configurations. Par exemple, le document US64732 divulgue un tel dispositif, à savoir en particulier un blaireau dont les poils sont alimentés en crème de rasage ou en savon depuis un réservoir interne, dont la capacité est réduite par actionnement d'un piston mobile dans le réservoir.  Devices for dispensing and applying a cosmetic product are known in the state of the art according to various configurations. For example, the document US64732 discloses such a device, namely in particular a shaving brush whose bristles are fed with shaving cream or soap from an internal reservoir, the capacity of which is reduced by actuation of a movable piston in the reservoir.
Afin d'améliorer ce dosage, c'est-à-dire le contrôle fin de la quantité de produit délivré, le document US 2004/0084343 divulgue un distributeur de rouge à lèvres dans lequel une vis sans fin actionne un piston mobile dans le corps creux du dispositif qui forme réservoir, afin d'en réduire progressivement le volume pour provoquer, à l'opposé du piston, l'expulsion contrôlée du rouge à lèvres. Néanmoins, le mécanisme divulgué est encombrant longitudinalement, rendant le distributeur lui-même encombrant. En outre, il ne donne pas d'indication sur la quantité de produit restant dans le distributeur.  In order to improve this dosage, that is to say the fine control of the quantity of product delivered, document US 2004/0084343 discloses a lipstick dispenser in which an endless screw actuates a movable piston in the body. hollow of the device that forms a reservoir, in order to gradually reduce the volume to cause, opposite the piston, the controlled expulsion of lipstick. Nevertheless, the disclosed mechanism is bulky longitudinally, making the dispenser itself bulky. In addition, it gives no indication of the amount of product remaining in the dispenser.
On connaît enfin par le document WO2012102427 un applicateur de produit cosmétique permettant de délivrer une quantité prédéfinie de produit. Sa structure comporte un récipient principal à l'intérieur duquel un piston étanche se déplace sur une tige filetée percée longitudinalement. La tige filetée est couplée à un support rotatif qui permet d'entraîner en déplacement le piston dans le corps du récipient. Ce type d'applicateur, dans lequel la tige filetée est en contact avec le produit cosmétique, est sensible à l'encrassement ce qui en limite l'usage à certains produits cosmétiques (très fluides, ne risquant pas de durcir ou de sécher, etc.), et empêche de pouvoir le recharger. Finally, the document WO2012102427 discloses a cosmetic product applicator for delivering a predefined quantity of product. Its structure comprises a main container inside which a sealed piston moves on a threaded rod pierced longitudinally. The threaded rod is coupled to a rotatable support which makes it possible to move the piston in displacement in the body of the container. This type of applicator, in which the threaded rod is in contact with the cosmetic product, is sensitive to fouling which limits its use to certain cosmetic products (very fluid, not likely to harden or dry, etc. .), and prevents being able to recharge it.
L'objet de l'invention est de proposer un dispositif de distribution et d'application d'un produit cosmétique ou de soin, adapté aux produits liquides à pâteux, résolvant au moins l'un des problèmes précités. The object of the invention is to provide a device for dispensing and applying a cosmetic or care product, suitable for liquid pasty products, solving at least one of the aforementioned problems.
Ainsi, l'invention porte sur un dispositif de distribution et d'application d'un produit cosmétique ou de soin liquide, semi-fluide ou pâteux. Le dispositif comporte un corps tournant allongé et creux et un fût extérieur allongé et creux aboutés l'un à l'autre, et mobiles en rotation l'un par rapport à l'autre. Un embout d'application est fixé en bout du corps tournant, Le corps tournant et le fût extérieur forment un volume intérieur dans lequel sont ménagés un cylindre percé comportant un conduit longitudinal, et un fût intérieur comportant une extrémité ouverte par laquelle est introduit le cylindre percé et une extrémité fermée de sorte à former réservoir pour le produit cosmétique ou de soin.  Thus, the invention relates to a device for dispensing and applying a cosmetic product or care liquid, semi-fluid or pasty. The device comprises an elongated and hollow rotating body and an elongated outer hollow and abutted to each other, and movable in rotation relative to each other. An applicator tip is fixed at the end of the rotating body. The rotating body and the outer casing form an interior volume in which are formed a pierced cylinder comprising a longitudinal duct, and an inner casing having an open end through which the cylinder is inserted. pierced and a closed end so as to form reservoir for the cosmetic or care product.
Le cylindre percé est fixe en translation par rapport au corps tournant à l'intérieur duquel il s'étend.  The pierced cylinder is fixed in translation relative to the rotating body within which it extends.
Le dispositif comporte un mécanisme de transformation d'une rotation du corps tournant par rapport au fût extérieur en un mouvement de translation du fût intérieur vis-à-vis du cylindre percé dans le volume intérieur formé par lesdits corps tournant et fût extérieur.  The device comprises a mechanism for transforming a rotation of the rotating body relative to the outer barrel in a translational movement of the inner barrel vis-à-vis the pierced cylinder in the inner volume formed by said rotating body and outer barrel.
Le mouvement relatif entre le fût intérieur formant réservoir et le cylindre percé pénétrant dans ledit fut intérieur par son extrémité ouverte entraîne une variation du volume intérieur disponible dans le fût. Une réduction de ce volume intérieur lorsque le fût intérieur, en remontant le long dudit cylindre percé provoque relativement une plus grande pénétration du cylindre dans le fût, entraîne une expulsion d'une quantité de produit correspondante à la réduction de volume via le conduit longitudinal du cylindre percé. Le mécanisme de transformation peut comporter une pièce filetée solidaire du fût intérieur, et l'ensemble formé par le corps tournant et le cylindre percé peut comporter une partie filetée adaptée à coopérer avec la pièce filetée solidaire du fût intérieur de sorte que la rotation dudit corps tournant entraîne la rotation de ladite partie filetée et la translation de ladite pièce filetée et du fût intérieur le long de ladite partie filetée, et corollairement la translation du fût intérieur vis-à-vis du cylindre percé. The relative movement between the inner drum forming reservoir and the pierced cylinder penetrating into said inner end by its open end causes a variation of the internal volume available in the barrel. A reduction of this internal volume when the inner shaft, going up along said pierced cylinder relatively causes greater penetration of the cylinder in the barrel, causes an expulsion of a quantity of product corresponding to the volume reduction via the longitudinal duct of the barrel. pierced cylinder. The transformation mechanism may comprise a threaded piece secured to the inner shaft, and the assembly formed by the rotating body and the pierced cylinder may comprise a threaded portion adapted to cooperate with the threaded piece integral with the inner shaft so that the rotation of said body turning causes the rotation of said threaded portion and the translation of said threaded piece and the inner barrel along said threaded portion, and corollary the translation of the inner barrel vis-à-vis the pierced cylinder.
Le dispositif peut comporter en outre un piston monté fixement à une extrémité du cylindre percé introduite par l'extrémité ouverte du fût intérieur, le piston comportant une surface périphérique dont le contact avec la surface intérieure du fût intérieur assure une étanchéité au produit, ledit piston comportant une ouverture centrale débouchant dans le conduit longitudinal du cylindre percé. Dans ce cas, le piston peut comporter une portion allongée s'étendant à l'intérieur du conduit longitudinal du cylindre percé.  The device may further comprise a piston mounted to a fixed end of the drilled cylinder introduced by the open end of the inner drum, the piston having a peripheral surface whose contact with the inner surface of the inner drum ensures a seal to the product, said piston having a central opening opening into the longitudinal duct of the pierced cylinder. In this case, the piston may comprise an elongated portion extending inside the longitudinal duct of the pierced cylinder.
Le dispositif peut comporter en outre un clapet anti-retour positionné en sortie du conduit longitudinal du cylindre percé.  The device may further comprise a non-return valve positioned at the outlet of the longitudinal duct of the pierced cylinder.
Selon un premier mode de réalisation, la partie filetée est formée par ou sur le cylindre percé, de sorte que ledit cylindre percé présente sur sa surface extérieure un filetage de sorte à former une vis, la pièce filetée étant une bague formant écrou sur ledit cylindre percé.  According to a first embodiment, the threaded portion is formed by or on the drilled cylinder, so that said drilled cylinder has on its outer surface a thread so as to form a screw, the threaded part being a nut ring on said cylinder. perforated.
La partie filetée peut être formée par adjonction d'une tige filetée creuse sur une surface extérieure du cylindre percé.  The threaded portion may be formed by adding a hollow threaded rod to an outer surface of the drilled cylinder.
Le dispositif peut comporter un manchon dans le corps tournant, ledit manchon étant libre en rotation vis-à-vis dudit corps tournant mais fixe en rotation vis-à-vis du fût extérieur, ladite bague étant à l'intérieur du manchon et ledit manchon et ladite bague étant configurés de sorte que ladite bague peut se translater dans le manchon mais y demeure fixe en rotation.  The device may comprise a sleeve in the rotating body, said sleeve being free in rotation with respect to said rotating body but fixed in rotation with respect to the outer barrel, said ring being inside the sleeve and said sleeve and said ring being configured so that said ring can translate into the sleeve but remains fixed in rotation.
Le manchon peut comporter, sur une face interne, au moins une rainure longitudinale, et la bague peut comporter au moins une encoche dans laquelle est introduite ladite rainure longitudinale de sorte que la bague est guidée en translation longitudinale dans le manchon sur ladite rainure longitudinale. Selon un deuxième mode de réalisation, la partie filetée est formée par une surface intérieure du corps tournant présentant un filetage, la pièce filetée étant une bague présentant sur une au moins une partie de sa périphérie un filetage coopérant avec le filetage de la surface intérieure du corps tournant. The sleeve may comprise, on an inner face, at least one longitudinal groove, and the ring may comprise at least one notch in which is introduced said longitudinal groove so that the ring is guided in longitudinal translation in the sleeve on said longitudinal groove. According to a second embodiment, the threaded portion is formed by an inner surface of the rotating body having a thread, the threaded part being a ring having on at least a portion of its periphery a thread cooperating with the threading of the inner surface of the rotating body.
La bague peut comporter deux portions filetées, diamétralement opposées, en saillie de la surface extérieure de la bague, et un guide longitudinal qui s'étend à l'intérieur du corps tournant de sorte à guider en translation longitudinale ladite bague à l'intérieur dudit corps tournant.  The ring may comprise two diametrically opposed threaded portions protruding from the outer surface of the ring, and a longitudinal guide which extends inside the rotating body so as to guide said ring in longitudinal translation within said ring. rotating body.
Dans tout mode de réalisation, le fût extérieur peut être transparent ou translucide, ou opaque.  In any embodiment, the outer cask may be transparent or translucent, or opaque.
De même, le fût intérieur peut être transparent ou translucide, ou opaque.  Similarly, the inner drum can be transparent or translucent, or opaque.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après. Other features and advantages of the invention will become apparent in the description below.

La figure 1 représente un dispositif conforme à un mode de réalisation de l'invention. La figure 2 représente en outre une vue éclatée du dispositif de la figure 1 , qui en détaille les pièces constitutives et permet d'en appréhender l'assemblage. Ce dispositif est décrit ci-après pour la distribution et l'application d'un produit cosmétique, mais est identiquement utilisable pour la distribution et l'application d'un produit de soin. Figure 1 shows a device according to one embodiment of the invention. Figure 2 further shows an exploded view of the device of Figure 1, which details the component parts and allows to apprehend the assembly. This device is described below for the distribution and application of a cosmetic product, but is identically usable for the distribution and application of a care product.
Le dispositif permet la distribution et l'application d'un produit cosmétique P, fluide, semi-fluide, ou pâteux. Le produit cosmétique P est contenu dans un réservoir appelé fût intérieur 1 . Le fût intérieur 1 a la forme, dans l'exemple ici représenté, d'un cylindre droit fermé à une extrémité et ouvert à l'autre.  The device allows the dispensing and application of a cosmetic product P, fluid, semi-fluid, or pasty. The cosmetic product P is contained in a tank called inner barrel 1. The inner shaft 1 has the shape, in the example shown here, of a right cylinder closed at one end and open to the other.
Le dispositif comporte un fût extérieur 2. Le fût extérieur 2 forme la partie inférieure du dispositif de distribution et d'application. Il est de forme allongée, et peut avoir une forme extérieure cylindrique ou prismatique. Le fût extérieur 2 comporte un fond 21 pouvant comporter une paroi de fermeture. Néanmoins, le fût extérieur comporte avantageusement une prise d'air. Cette prise d'air peut être ménagée au travers la paroi du fond 21 . La prise d'air permet les échanges d'air entre l'intérieur et l'extérieur du fût extérieur 2. Elle permet notamment l'entrée d'air dans le fût extérieur lors du mouvement, ci-après décrit, du fût intérieur 1 dans le fût extérieur 2 pendant la distribution de produit. Le fût extérieur 2 comporte également une face opposée 22 ouverte, dans laquelle est introduite le fût intérieur 1 . La forme intérieure du fût extérieur 2 correspond à un jeu près à la forme externe du fût intérieur 1 . Cela permet une translation longitudinale, ou autrement dit un coulissement selon un axe principal (A) du dispositif, du fût intérieur 1 dans le fût extérieur 2.  The device comprises an outer drum 2. The outer drum 2 forms the lower part of the dispensing and application device. It is elongated in shape and may have a cylindrical or prismatic external shape. The outer barrel 2 comprises a bottom 21 may include a closure wall. Nevertheless, the outer barrel advantageously comprises an air intake. This air intake can be formed through the wall of the bottom 21. The air intake allows the exchange of air between the inside and the outside of the outer drum 2. It allows in particular the air inlet into the outer drum during the movement, described below, of the inner drum 1 in the outer drum 2 during product dispensing. The outer barrel 2 also has an opposite opposite face 22 into which the inner barrel 1 is inserted. The inner shape of the outer shaft 2 corresponds to a clearance close to the outer shape of the inner shaft 1. This allows a longitudinal translation, or in other words a sliding along a main axis (A) of the device, of the inner shaft 1 in the outer shaft 2.
Le fût extérieur 2 est avantageusement transparent ou translucide, ce qui permet de visualiser la position du fût intérieur 1 dans le dispositif. La position du fût intérieur 1 dans le dispositif correspond en outre à une quantité de produit restant donnée. En d'autres termes, visualiser la position du fût intérieur 1 permet à l'utilisateur de visualiser la quantité de produit restante, ou, réciproquement, la quantité de produit consommé. The outer cask 2 is advantageously transparent or translucent, which makes it possible to visualize the position of the inner cask 1 in the device. The position of the inner drum 1 in the device also corresponds to a quantity of product remaining given. In other words, visualizing the position of the inner drum 1 allows the user to view the amount of product remaining, or, conversely, the amount of product consumed.
Si le fût intérieur 1 est lui-même transparent ou translucide, le produit est directement visible. Cela est esthétiquement valorisant, et permet en outre à l'utilisateur d'identifier le produit souhaité par son apparence, notamment sa couleur, sa brillance, et/ou ses autres caractéristiques visuelles.  If the inner drum 1 is itself transparent or translucent, the product is directly visible. This is aesthetically enhancing, and further allows the user to identify the desired product by its appearance, including its color, brilliance, and / or other visual characteristics.
Le dispositif comporte également un élément qui forme sa partie supérieure et qui est appelé corps tournant 3. Le corps tournant 3 est de forme allongée, et peut avoir une forme extérieure cylindrique ou prismatique, et notamment une forme extérieure correspondant à la forme extérieure du fût inférieur 2. Le corps tournant 3 est abouté au fût extérieur 2. Le corps tournant 3 peut être pivoté vis-à-vis de ce dernier autour de l'axe principal (A) du dispositif. Des exemples de liaisons pouvant être mis en œuvre, entre le corps tournant 3 et le fût extérieur 2 sont décrits ci-après en référence aux figures 3, 6 et 9.  The device also comprises an element which forms its upper part and which is called rotating body 3. The rotating body 3 is of elongated shape, and may have an outer cylindrical or prismatic shape, and in particular an outer shape corresponding to the outer shape of the barrel 2. The rotating body 3 is abutted with the outer barrel 2. The rotating body 3 can be pivoted with respect thereto around the main axis (A) of the device. Examples of connections that can be implemented between the rotating body 3 and the outer shaft 2 are described below with reference to FIGS. 3, 6 and 9.
Le corps tournant 3 est désigné ainsi car il constitue l'élément que l'utilisateur tourne, par rapport au fût extérieur 2, afin de provoquer la distribution de produit cosmétique par le dispositif.  The rotating body 3 is so designated because it is the element that the user rotates, with respect to the outer shaft 2, to cause the dispensing of cosmetic product by the device.
Le corps tournant 3 est creux et définit ainsi, avec le fût extérieur 2 auquel il est lié, un volume intérieur du dispositif de distribution et d'application.  The rotating body 3 is hollow and thus defines, with the outer shaft 2 to which it is connected, an interior volume of the dispensing device and application.
Un embout applicateur 4 est fixé en bout du corps tournant 3. L'embout applicateur 4 présente une surface d'application 41 , par laquelle le produit cosmétique P est distribué et qui en permet l'application, par exemple en une couche mince et régulière sur la peau de l'utilisateur du dispositif.  An applicator tip 4 is fixed at the end of the rotating body 3. The applicator tip 4 has an application surface 41, through which the cosmetic product P is dispensed and which allows its application, for example in a thin and regular layer on the skin of the user of the device.
Le dispositif comporte, dans le volume intérieur formé par le corps tournant 3 et le fût extérieur 2, d'une part le fût intérieur 1 , mais également un cylindre percé 5. Le cylindre percé 5 comporte sur toute sa longueur, c'est-à-dire le long de son axe d'extension confondu avec l'axe principal (A), un conduit longitudinal 51 . Le conduit longitudinal 51 présente une section constante ou évolutive.  The device comprises, in the internal volume formed by the rotating body 3 and the outer shaft 2, on the one hand the inner shaft 1, but also a pierced cylinder 5. The pierced cylinder 5 comprises over its entire length, that is, that is to say along its extension axis coincides with the main axis (A), a longitudinal duct 51. The longitudinal duct 51 has a constant or progressive section.
Dans les différents modes de réalisation de l'invention, le cylindre percé 5 est fixe en translation par rapport au corps tournant 3, à l'intérieur duquel il s'étend. Selon le mode de réalisation considéré, le cylindre percé 5 peut être fixe ou mobile en rotation par rapport au corps tournant 3. Dans le mode de réalisation des figures 1 à 6, le cylindre percé 5 est fixe en rotation par rapport au corps tournant 3. In the various embodiments of the invention, the pierced cylinder 5 is fixed in translation relative to the rotating body 3, inside which he's stretching. According to the embodiment considered, the pierced cylinder 5 can be fixed or rotatable relative to the rotating body 3. In the embodiment of Figures 1 to 6, the pierced cylinder 5 is fixed in rotation relative to the rotating body 3 .
Selon diverses variantes des divers modes de réalisation de l'invention, le cylindre percé 5 peut soit être fixé au corps tournant 3 directement ou via une pièce intermédiaire qui peut être l'embout d'application 4, ou bien être formé de manière monobloc avec le corps tournant 3.  According to various variants of the various embodiments of the invention, the pierced cylinder 5 can either be fixed to the rotating body 3 directly or via an intermediate piece which can be the applicator tip 4, or can be integrally formed with rotating body 3.
Le cylindre percé 5 est introduit dans le fût intérieur 1 par son extrémité ouverte 22.  The pierced cylinder 5 is introduced into the inner drum 1 by its open end 22.
Le dispositif comporte un mécanisme de transformation d'une rotation du corps tournant 3 par rapport au fût extérieur 2 en un mouvement de translation du fût intérieur 1 vis-à-vis du cylindre percé 5.  The device comprises a mechanism for transforming a rotation of the rotating body 3 with respect to the outer drum 2 in a translation movement of the inner drum 1 with respect to the pierced cylinder 5.
Ainsi, dans le volume intérieur formé par lesdits corps tournant et fût extérieur, c'est le fût intérieur 1 qui est mobile, tandis que le cylindre percé 5 reste fixe longitudinalement. Du fait du mouvement du fût intérieur 1 , le cylindre percé pénètre plus ou moins dans ledit fût intérieur, ce qui en fait varier le volume intérieur disponible pour le stockage du produit cosmétique P.  Thus, in the internal volume formed by said rotating body and outer barrel, it is the inner shaft 1 which is movable, while the pierced cylinder 5 remains fixed longitudinally. Due to the movement of the inner drum 1, the pierced cylinder penetrates more or less into said inner drum, which makes it vary the internal volume available for the storage of the cosmetic product P.
Une diminution du volume disponible dans le cylindre intérieur P entraîne une expulsion d'une quantité correspondante de produit P via le conduit longitudinal 51 du cylindre percé 5.  A decrease in the volume available in the inner cylinder P causes an expulsion of a corresponding quantity of product P via the longitudinal duct 51 of the pierced cylinder 5.
Le mécanisme de transformation du mouvement peut avoir diverses configurations, dont deux variantes sont détaillées à l'appui des figures 3 à 6 d'une part, et 7 à 10 d'autre part. Ces exemples de mécanismes, ainsi que celui de la figure 1 sont basés sur une pièce filetée (présentant un filetage femelle ou mâle selon les variantes considérées de l'invention) liée au fût intérieur 1 , et sur le fait que l'ensemble formé par le corps tournant 3 et le cylindre percé 5 comporte une partie filetée (mâle ou femelle selon la variante considérée) adaptée à coopérer avec la pièce filetée.  The mechanism of transformation of the movement can have various configurations, of which two variants are detailed in support of Figures 3 to 6 on the one hand, and 7 to 10 on the other hand. These examples of mechanisms, as well as that of FIG. 1, are based on a threaded part (having a female or male thread according to the considered variants of the invention) connected to the inner shaft 1, and on the fact that the assembly formed by the rotating body 3 and the pierced cylinder 5 comprises a threaded portion (male or female according to the variant considered) adapted to cooperate with the threaded part.
La rotation dudit ensemble formé par le corps tournant et le cylindre percé entraîne la translation de ladite pièce filetée et du fût intérieur dans ledit corps tournant, et corollairement du fût intérieur vis-à-vis du cylindre percé. Dans l'exemple de la figure 1 , la pièce filetée est une bague 71 présentant un filetage intérieur, appelé filetage femelle. La bague 71 est fixée à l'extrémité ouverte 22 du fût intérieur 1 , qu'elle obstrue sauf au niveau de son ouverture filetée. The rotation of said assembly formed by the rotating body and the pierced cylinder causes the translation of said threaded piece and the inner barrel in said rotating body, and corollary of the inner barrel vis-à-vis the pierced cylinder. In the example of Figure 1, the threaded part is a ring 71 having an internal thread, called female thread. The ring 71 is fixed to the open end 22 of the inner shaft 1, which it obstructs except at its threaded opening.
En remontant dans le corps tournant, le fût intérieur 1 remonte le long du cylindre percé 5, ce qui a pour effet de diminuer le volume intérieur disponible dans le fût intérieur 1 pour le produit P, et de provoquer l'expulsion d'une quantité de produit P du fût intérieur 1 par le conduit 51 du cylindre percé 5.  Going up in the rotating body, the inner drum 1 rises along the drilled cylinder 5, which has the effect of reducing the internal volume available in the inner drum 1 for the product P, and causing the expulsion of a quantity of product P of the inner drum 1 through the conduit 51 of the pierced cylinder 5.
Le dispositif peut comporter, comme c'est le cas dans l'exemple représenté à la figure 1 , un capuchon ou capot 8. Le capot 8 permet de fermer le dispositif afin d'éviter que du produit cosmétique ne soit répandu, de protéger l'embout de distribution, et d'éviter un actionnement non souhaité du dispositif.  The device may comprise, as is the case in the example shown in FIG. 1, a cap or cover 8. The cover 8 makes it possible to close the device in order to prevent the cosmetic product from being spilled, to protect the device. dispensing tip, and to avoid unwanted actuation of the device.
Le capot 8 peut également avoir un rôle esthétique. Il peut porter un logo ou une inscription.  The hood 8 may also have an aesthetic role. He may wear a logo or inscription.
La figure 3 présente, selon une vue en coupe transversale, une variante du mode de réalisation des figures 1 et 2. Une vue éclatée de la variante de réalisation de la figure 3 est présentée à la figure 4. La cinématique de fonctionnement de cette variante est identique à celle décrite ci-avant en référence auxdites figures 1 et 2. Néanmoins, la variante de la figure 4 diffère de celle présentée aux figures 1 et 2 essentiellement par les caractéristiques décrites ci-après. Un piston 52 est fixé à l'extrémité du cylindre percé. Le piston 52 comporte une ouverture centrale 53 qui débouche dans le conduit 51 du cylindre percé 5. L'ouverture centrale 53 assure ainsi une communication fluidique entre une surface frontale 54 du piston 52, qui est en contact avec le produit P dans le cylindre percé 5, et ledit conduit 51 . Le piston 52 est configuré de sorte à présenter une surface périphérique 55 en contact étanche avec la paroi intérieure 1 1 du fût intérieur 1 . Ainsi, lorsque le fût intérieur 1 remonte autour du cylindre percé 5, la diminution de volume disponible dans le fût intérieur 1 sous la surface frontale 54 du piston 52 entraîne l'expulsion d'une quantité de produit P correspondant à cette diminution. Le produit est expulsé via l'ouverture centrale 53 du piston 52, puis le conduit 51 du cylindre percé, avant d'atteindre l'embout d'application 4 qu'il traverse par des orifices distributeurs 42 avant d'atteindre la surface d'application 41 . FIG. 3 shows, in a cross-sectional view, a variant of the embodiment of FIGS. 1 and 2. An exploded view of the variant embodiment of FIG. 3 is presented in FIG. 4. The operating kinematics of this variant is identical to that described above with reference to said Figures 1 and 2. Nevertheless, the variant of Figure 4 differs from that shown in Figures 1 and 2 essentially by the characteristics described below. A piston 52 is attached to the end of the drilled cylinder. The piston 52 has a central opening 53 which opens into the conduit 51 of the pierced cylinder 5. The central opening 53 thus provides fluid communication between a front surface 54 of the piston 52, which is in contact with the product P in the pierced cylinder 5, and said duct 51. The piston 52 is configured to have a peripheral surface 55 in sealing contact with the inner wall 1 1 of the inner shaft 1. Thus, when the inner shaft 1 rises around the pierced cylinder 5, the decrease in volume available in the inner shaft 1 under the front surface 54 of the piston 52 causes the expulsion of a quantity of product P corresponding to this reduction. The product is expelled via the central opening 53 of the piston 52, then the conduit 51 of the pierced cylinder, before reaching the applicator tip 4 which it passes through dispensing orifices 42 before reaching the application surface 41.
Le piston 52 permet une expulsion complète ou presque complète du produit, le volume résiduel dans le fût intérieur 1 étant nul ou quasiment nul lorsque ledit fût intérieur est remonté au maximum dans le dispositif, et que la face frontale 54 du piston 52 est au contact ou à proximité du fond du fût intérieur 1 . En outre, le piston évite que la partie filetée ne soit au contact de produit cosmétique lors de l'utilisation du dispositif. Cela évite tout encrassement de ladite partie filetée, et peut, le cas échéant, permettre de remplir à nouveau le dispositif en produit cosmétique sans qu'il soit nécessaire de nettoyer la partie filetée.  The piston 52 allows a complete or almost complete expulsion of the product, the residual volume in the inner drum 1 being zero or virtually zero when said inner drum is raised to the maximum in the device, and that the front face 54 of the piston 52 is in contact or near the bottom of the inner drum 1. In addition, the piston prevents the threaded portion from being in contact with cosmetic product during use of the device. This avoids any fouling of said threaded portion, and may, if necessary, allow to fill the device again cosmetic product without the need to clean the threaded portion.
Le conduit 51 a, dans l'exemple représenté, une section évolutive. En particulier, le conduit 51 présente une restriction progressive de son entrée (à son extrémité introduite dans le fût intérieur 1 ) à sa sortie. L'évolution de la section, notamment sa restriction, et/ou une forme particulière du conduit 51 peuvent par exemple permettre la déstructuration de la formule et l'éclatement de billes comportant un fluide présentes dans le produit P (par exemple un brillant à lèvres, pour améliorer le brillant obtenu), juste avant la distribution dudit produit P.  The conduit 51 has, in the example shown, an evolutionary section. In particular, the conduit 51 has a progressive restriction of its input (at its end inserted into the inner drum 1) at its output. The evolution of the section, in particular its restriction, and / or a particular form of the conduit 51 may for example allow the destructuring of the formula and the bursting of beads comprising a fluid present in the product P (for example a lip gloss to improve the obtained gloss), just before dispensing said product P.
Dans la variante de l'invention ici représentée, un clapet anti-retour 91 est disposé entre la sortie du conduit 51 et l'embout d'application 4. Le clapet anti-retour 91 permet de protéger le produit P contenu dans le dispositif de l'atmosphère extérieure. Le clapet anti-retour 91 permet également, dans une certaine mesure, d'éviter que le corps tournant ne soit actionné dans le sens de rotation tendant à ré-aspirer du produit vers le fût intérieur 1 .  In the variant of the invention shown here, a non-return valve 91 is disposed between the outlet of the duct 51 and the application nozzle 4. The non-return valve 91 makes it possible to protect the product P contained in the device the outside atmosphere. The non-return valve 91 also makes it possible, to a certain extent, to prevent the rotating body from being actuated in the direction of rotation tending to re-suck the product towards the inner drum 1.
De manière avantageuse, le clapet anti-retour contribue à l'étanchéité générale du dispositif de distribution lorsque ce dernier est en position inversé (embout d'application 4 orienté vers le bas), par exemple dans le sac à main d'une utilisatrice.  Advantageously, the non-return valve contributes to the general sealing of the dispensing device when the latter is in the inverted position (applicator tip 4 facing downwards), for example in the handbag of a user.
Le clapet anti-retour 91 peut également aider à l'éclatement de billes présentes, le cas échéant, dans le produit P. Une autre différence entre le dispositif des figures 1 et 2 et celui des figures 3 à 6 est la constitution de la partie filetée du cylindre percé. Tandis que dans le dispositif des figures 1 et 2, le cylindre percé 5 et la partie filetée sont monoblocs, dans la variante des figures 3 à 6 la partie filetée est formée par une tige filetée creuse 56 qui est adjointe au cylindre percé 5. En particulier, la tige filetée creuse 56 forme un fourreau autour du cylindre percé 5, c'est-à-dire autour de la surface extérieure du cylindre percé. The non-return valve 91 can also help the bursting of beads present, if any, in the product P. Another difference between the device of Figures 1 and 2 and that of Figures 3 to 6 is the constitution of the threaded portion of the pierced cylinder. While in the device of Figures 1 and 2, the drilled cylinder 5 and the threaded portion are monobloc, in the variant of Figures 3 to 6 the threaded portion is formed by a hollow threaded rod 56 which is associated with the drilled cylinder 5. In In particular, the hollow threaded rod 56 forms a sleeve around the pierced cylinder 5, that is to say around the outer surface of the pierced cylinder.
Comme cela est bien visible à la figure 5, afin de maintenir la tige filetée creuse 56 fixe en rotation par rapport au cylindre percé 5, la tige filetée creuse 56 est munie, sur une portion de sa surface intérieure, d'encoches 57 de forme correspondant à celle d'ergots 58 portés par le cylindre percé 5.  As is clearly visible in FIG. 5, in order to keep the hollow threaded rod 56 fixed in rotation relative to the pierced cylinder 5, the hollow threaded rod 56 is provided, on a portion of its inner surface, with notches 57 of shape. corresponding to that of pins 58 carried by the pierced cylinder 5.
La figure 6 représente une vue de détail du dispositif des figures 3 à 5, à proximité de la jonction entre la partie basse du dispositif comportant le fût extérieur 2 et la partie haute comportant notamment le cylindre percé 5 et le corps tournant 3 (non représenté sur la figure 6).  FIG. 6 represents a detailed view of the device of FIGS. 3 to 5, near the junction between the lower part of the device comprising the outer shank 2 and the upper part comprising in particular the drilled cylinder 5 and the rotating body 3 (not shown in Figure 6).
La connexion entre le fût extérieur 2 et le corps tournant 3 est réalisée, dans l'exemple ici représenté, par un joint torique 92 inséré dans des gorges formées respectivement sur une surface intérieure du corps tournant 3 et sur une surface extérieure du fût extérieur 2.  The connection between the outer barrel 2 and the rotating body 3 is carried out, in the example represented here, by an O-ring 92 inserted into grooves respectively formed on an inner surface of the rotating body 3 and on an outer surface of the outer barrel 2 .
Comme montré à la figure 6, le piston 52 peut comporter une portion oblongue 521 insérée dans le conduit 5. Le piston 52 est lié au cylindre creux 5 grâce à une saillie 522 de la surface interne du conduit 51 adapté à se clipser dans une rainure circulaire 523 de la portion oblongue 521 .  As shown in FIG. 6, the piston 52 may comprise an oblong portion 521 inserted in the duct 5. The piston 52 is connected to the hollow cylinder 5 thanks to a projection 522 of the inner surface of the duct 51 adapted to snap into a groove circular 523 of the oblong portion 521.
Afin de permettre la translation de la bague 71 le long de la partie filetée du cylindre creux 5, ladite bague 71 doit être libre en translation vis-à-vis du fût extérieur 2 et du corps tournant 3 tout en étant maintenue fixe en rotation vis-à-vis du fût extérieur 2. A cette fin, le dispositif comporte un manchon 10, s'étendant dans le corps tournant, qui est fixe par rapport au fût extérieur 2 et qui présente des guides en translation de la bague 71 .  In order to allow the translation of the ring 71 along the threaded portion of the hollow cylinder 5, said ring 71 must be free in translation vis-à-vis the outer shaft 2 and the rotating body 3 while being held fixed in rotation screws 2. To this end, the device comprises a sleeve 10, extending in the rotating body, which is fixed relative to the outer shaft 2 and which has guides in translation of the ring 71.
Ainsi, le fût extérieur 2 comporte en sa partie supérieure un crantage Thus, the outer shaft 2 has in its upper part a notch
21 adapté à s'engrener avec une denture correspondante 101 dudit manchon, ce qui bloque le manchon en rotation vis-à-vis du fût extérieur 2. Le manchon comporte sur sa surface interne des rainures longitudinales 102, c'est-à-dire parallèles à l'axe principal (A), le long desquelles la bague 71 est guidée. La bague 71 peut pour cela présenter, sur sa périphérie, des encoches 72 qui coulissent sur les rainures longitudinale 102. 21 adapted to mesh with a corresponding toothing 101 of said sleeve, which blocks the sleeve in rotation vis-à-vis the outer shaft 2. The sleeve has on its inner surface longitudinal grooves 102, that is to say parallel to the main axis (A), along which the ring 71 is guided. The ring 71 may for this purpose have, on its periphery, notches 72 which slide on the longitudinal grooves 102.
Le capot du dispositif a été omis aux figures 3 et 4. Néanmoins, comme le suggère la forme extérieure de l'embout d'application 4 ainsi que du corps tournant 3, dans cette variante de l'invention le capot couvre l'embout d'application 4 et uniquement une faible portion extrémale du corps tournant 3.  The cover of the device has been omitted from FIGS. 3 and 4. Nevertheless, as suggested by the external shape of the applicator tip 4 as well as the rotating body 3, in this variant of the invention the cover covers the mouthpiece 4 application and only a small extremal portion of the rotating body 3.
Il est bien évident que les caractéristiques distinctives du dispositif des figures 3 à 6, notamment la présence d'un piston 52 en bout du cylindre percé 5, la constitution de la partie filetée dudit cylindre percé 5, les moyens pour assurer la translation de la pièce filetée (par exemple la bague 71 ), la forme du capot 8, etc., peuvent être appliquées (ou non) indépendamment l'un de l'autre à tout dispositif ayant une configuration analogue au dispositif des figures 1 et 2.  It is obvious that the distinguishing characteristics of the device of FIGS. 3 to 6, in particular the presence of a piston 52 at the end of the pierced cylinder 5, the constitution of the threaded portion of said pierced cylinder 5, the means for ensuring the translation of the threaded part (for example the ring 71), the shape of the cover 8, etc. may be applied (or not) independently of each other to any device having a configuration similar to the device of FIGS. 1 and 2.
La figure 7 représente, selon une vue schématique en coupe un exemple d'un autre mode de réalisation de l'invention. La figure 8 illustre le dispositif de la figure 7 selon une vue éclatée.  Figure 7 shows, in a schematic sectional view an example of another embodiment of the invention. Figure 8 illustrates the device of Figure 7 in an exploded view.
Dans le mode de réalisation des figures 7 et 8, et tel que représenté selon la vue partielle de la figure 9, la partie filetée de l'ensemble formé par le corps tournant 3 et le cylindre percé 5 est formée sur une surface intérieure 31 du corps tournant 3, ladite surface intérieure 31 présentant un filetage. Le filetage formé sur la surface intérieure 31 est donc un filetage femelle. La pièce filetée est une bague 71 ' lié rigidement au fût intérieur 1 ou formée, comme dans l'exemple ici représenté, intégralement avec ledit fût intérieur 1 .  In the embodiment of Figures 7 and 8, and as shown in the partial view of Figure 9, the threaded portion of the assembly formed by the rotating body 3 and the drilled cylinder 5 is formed on an inner surface 31 of the rotating body 3, said inner surface 31 having a thread. The thread formed on the inner surface 31 is therefore a female thread. The threaded piece is a ring 71 'rigidly connected to the inner shaft 1 or formed, as in the example here shown, integrally with said inner shaft 1.
La bague 71 ' comporte sur une partie de sa périphérie un filetage coopérant avec le filetage de la surface intérieure 31 du corps tournant 3. Il s'agit donc d'un filetage mâle, de diamètre correspondant et de même pas.  The ring 71 'has on a portion of its periphery a thread cooperating with the thread of the inner surface 31 of the rotating body 3. It is therefore a male thread, of corresponding diameter and not even.
Dans l'exemple de réalisation ici représenté, la bague 71 ' est solidaire et formée intégralement, par exemple par moulage, avec le fût intérieur 1 . Elle comporte deux portions filetées 73, ménagées en partie haute du fût intérieur 1 , c'est-à-dire à son extrémité ouverte. Afin de guider la bague 71 ' (et donc le fût intérieur 1 ) en translation dans le dispositif et d'empêcher ladite bague 71 ' de tourner, un guide longitudinal 23 est formé en bout du fût extérieur 2. Le guide longitudinal s'étend à l'intérieur du corps tournant 3, afin de guider la remontée du fût intérieur 1 dans ledit corps tournant 3. In the embodiment shown here, the ring 71 'is integral and integrally formed, for example by molding, with the inner shaft 1. It comprises two threaded portions 73, formed in the upper part of the inner shaft 1, that is to say at its open end. In order to guide the ring 71 '(and thus the inner shaft 1) in translation in the device and to prevent said ring 71' from rotating, a longitudinal guide 23 is formed at the end of the outer shaft 2. The longitudinal guide extends inside the rotating body 3, to guide the raising of the inner shaft 1 in said rotating body 3.
Dans l'exemple ici représenté, le guide longitudinal 23 comporte deux ouvertures longitudinales 24 dans lesquelles les portions filetées 73 de la bague 71 ', qui font saillie du reste de la bague, peuvent coulisser.  In the example shown here, the longitudinal guide 23 comprises two longitudinal openings 24 in which the threaded portions 73 of the ring 71 ', which project from the rest of the ring, can slide.
Tout comme le mode de réalisation des figures 3 à 6, le dispositif des figures 7 à 9 comporte un piston 52. Le piston 52 permet notamment, comme expliqué en référence aux figures 3 à 6, une expulsion de la totalité ou presque du produit P, et d'éviter l'encrassement de la partie filetée lors de l'utilisation du dispositif.  Just like the embodiment of FIGS. 3 to 6, the device of FIGS. 7 to 9 comprises a piston 52. The piston 52 allows, in particular, as explained with reference to FIGS. 3 to 6, an expulsion of all or almost all of the product P , and to avoid fouling of the threaded portion when using the device.
Les figures 7 et 8, et la figure 10, illustrent un détail de réalisation du mode de réalisation représenté de l'invention. Un socle 43 de l'embout d'application 4 est disposé à l'extrémité du dispositif et permet son assemblage. En particulier, le socle 43 est adapté d'une part à son clipsage au cylindre percé 5, et aux moyens de guidage 23 du fût extérieur d'autre part. Ainsi le socle 43, et donc plus généralement l'embout 4, ainsi que le cylindre percé 5, restent fixes par rapport au fût extérieur 2 lorsque le corps tournant 3 est tourné afin de provoquer la translation du fût intérieur dans le dispositif.  Figures 7 and 8, and Figure 10, illustrate a detail of the embodiment of the invention shown. A base 43 of the applicator tip 4 is disposed at the end of the device and allows its assembly. In particular, the base 43 is adapted firstly to its clipping to the pierced cylinder 5, and to the guiding means 23 of the outer shaft on the other hand. Thus the base 43, and therefore more generally the tip 4, and the pierced cylinder 5, remain fixed relative to the outer shaft 2 when the rotating body 3 is rotated to cause the translation of the inner shaft in the device.
Le socle 43 ménage également un volume extrémal 44 adapté à recevoir le clapet anti-retour 91 . Enfin, le socle 43 est configuré pour la fixation, par exemple par clipsage, d'un chapeau 45 comportant la surface d'application 41 .  The base 43 also has an end volume 44 adapted to receive the non-return valve 91. Finally, the base 43 is configured for fixing, for example by clipping, a cap 45 comprising the application surface 41.
Il est notable que la surface d'application peut présenter des formes diverses, selon le type de produit et la zone d'application visée.  It is notable that the application surface may have various shapes, depending on the type of product and the intended application area.
Ainsi, la surface d'application peut être sensiblement conique, comme dans l'exemple des figures 7 à 9, ou être sensiblement plane et inclinée vis-à-vis de l'axe principal (A) du dispositif, comme dans l'exemple des figures 3 à 6, ou encore être bombée comme dans l'exemple des figures 1 et 2. Les dispositifs présentés sont notamment adaptés à l'application d'un brillant à lèvres, plus couramment désigné par le terme anglophone « gloss ». Thus, the application surface may be substantially conical, as in the example of Figures 7 to 9, or be substantially flat and inclined vis-à-vis the main axis (A) of the device, as in the example Figures 3 to 6, or be curved as in the example of Figures 1 and 2. The devices presented are particularly adapted to the application of a lip gloss, more commonly referred to by the English term "gloss".
L'invention ainsi développée offre un dispositif applicateur de produit cosmétique ou de soin permettant un dosage précis de la quantité de produit à délivrer (du fait du dosage par rotation d'un corps tournant), et selon la variante de l'invention considérée, évitant l'encrassement du mécanisme de distribution et/ou indiquant la quantité de produit restante et, réciproquement, consommée.  The invention thus developed provides an applicator device for a cosmetic or care product that allows precise dosing of the quantity of product to be delivered (due to rotational dosing of a rotating body), and according to the variant of the invention in question, avoiding clogging of the distribution mechanism and / or indicating the amount of product remaining and reciprocally consumed.
