Definitions

  • the invention relates to the field of devices for tight packaging and application of a product, in particular a cosmetic or care product and in particular a solidified product stick.
  • Cosmetic product means a product as defined in Council Directive 93/35 / EEC of 14 June 1993.
  • a slider applicator for solidified product comprises a hollow body and a support base for the product.
  • the base is driven in translation by a slider protruding from the hollow body.
  • Such an applicator has the disadvantage that the user has difficulty in applying the necessary effort to release the product. This is particularly troublesome for products strongly adhering to the side wall of the hollow body.
  • the user is obliged to exert a high thrust force to unstick the product stick from the side wall. When the detachment occurs, this significant effort causes the almost complete release of the product which is no longer guided by the side walls and may fall. There is a need to better regulate the output of the product stick.
  • the patent US 1 675 365 discloses a tube for lip stick equipped with an output mechanism of the lip stick.
  • the mechanism comprises a worm in the output shaft of the lip stick.
  • An outer wheel rotates the worm through a shaft passing through the tube.
  • the user holds the tube in one hand and the wheel in the other. Nevertheless, it is desirable to manipulate the output of the lip stick with the same hand that holds the tube to let the other hand free. This other hand can then be used to hold a mirror to facilitate product application.
  • the patent US 1,712,840 discloses a tube for lipstick equipped with another output mechanism of the lip stick.
  • the mechanism comprises a pinion mounted to rotate on a fixed axis relative to the tube.
  • the pinion drives in translation an inner drawer, equipped with teeth and pushing the lip stick.
  • the axis of rotation of the pinion passes through the tube.
  • the pinion is rotated by a disk disposed on one side of the square tube.
  • Manual actuation of the disc is complex because it is difficult to hold a tube firmly while pressing the disc aside without rotating the tube about its axis.
  • the drive disc protrudes from the tube in two directions, both axially in the axis of the pinion, and radially to be accessible to the wearer's fingers. There is a need to improve the bulkiness and maneuverability of the lip stick output mechanism.
  • the patent US 2,589,000 describes a butter dispenser.
  • the dispenser comprises a hollow body open on both sides and a follower base pressing the stick of butter towards an opening of the body.
  • a drive wheel is rotatably mounted in the follower base and has a knurled portion of a diameter protruding from the body, and small diameter gear teeth cooperating with teeth of the dispenser body.
  • the axis of rotation of the wheel passes through a groove extending along the body and in particular next to the place where the butter is housed before being distributed.
  • the groove passing through the axis of rotation of the drive wheel puts the butter in direct contact with the outside.
  • Such a distributor does not suitable for sealingly packaging a cosmetic or care product.
  • the drive wheel extends on one side of the square tube, so it is still difficult to maneuver the device and the size of such a device is important.
  • the patent US 3,989,392 discloses a stick product dispenser apparatus.
  • a body includes a gear wheel that drives a piston pushing the product.
  • the axis of the wheel is fixed relative to the body.
  • Such a wheel has the disadvantage of not multiplying the thrust force of the piston so that the dispenser is not suitable for a product adhering to the wall of the dispenser.
  • the invention proposes a device for packaging and applying a cosmetic or care product that overcomes at least one of the aforementioned drawbacks.
  • An object of the invention is to provide a device that allows to regulate the output of the product while improving the maneuverability of the device for output or return the product.
  • the device for packaging and / or applying a cosmetic or care product comprises, a hollow body forming a housing for the product, a base for supporting the product and means for driving the product. translation of the base so as to vary the volume of the housing.
  • Said drive means comprise an actuator member rotatably mounted about an axis and movable along the hollow body integrally with the base.
  • Said actuating member comprises at least one portion alternately forming a biasing surface configured to be biased by manual contact and an actuating surface configured to be engaged along the hollow body.
  • the actuating surface is engaged along an outer surface of the hollow body.
  • the same portion of the actuating member alternately contacts the finger of the user or the user and then with the hollow body.
  • This has the effect that the biasing surface is opposite the hollow body.
  • the user can press the hollow body and the actuator between the thumb and the rest of the same hand without the device pivoting sideways.
  • the user can rotate the actuating member.
  • the portion initially solicited manually moves to engage the outer face or outer surface of the hollow body and on a given height of said hollow body. This has the effect of moving the axis of rotation of the actuating member along the hollow body and to drive the base in translation. The force exerted on the solicitation surface is thus reduced. This helps to regulate the output of the product.
  • the hollow body has an interior zone comprising the housing.
  • the base delimits the housing in relation to the rest of the interior area.
  • the axis of the actuator extends out of the inner zone.
  • the axis of rotation of the actuating member may extend exclusively outside the hollow body provided for housing the cosmetic product.
  • the axis of rotation of the actuating member is entirely offset with respect to the hollow body supporting the cosmetic product. This has the effect that the actuator can move radially outside the housing of the product in a direction substantially parallel to the axis of extension of the cosmetic product.
  • the actuating member does not extend in the extension of the product. More generally, the actuating member is not contained in the hollow body. A device of reduced axial size is thus obtained.
  • the axis of rotation of the drive member is perpendicular to the axis of extension of the product.
  • the base may have a product-contacting surface extending substantially over the entire cross section of the product housing. It is also possible, when the compactness of the product is sufficient, that the surface in contact of the base with the product does not extend over the entire cross section of the housing, since the translation of the base causes all the product.
  • the hollow body has a dispensing opening for passing the product during the movement of the base.
  • the opening may be at the end of the housing so that the product is directly accessible to the user when the base pushes the product out of the housing.
  • the base is movable in translation along a sliding axis.
  • the opening may be in alignment with the base in the sliding axis.

  • the housing may have an elongate shape along the axis of sliding in the case for example of lipstick tube.
  • the housing may also have a flattened shape having a cross section perpendicular to the sliding axis wider than the thickness of the housing in the sliding axis. This case may be suitable for distributors of low-compact products that nevertheless need to be pushed together.
  • the base is movable between a low position, furthest from the opening along the sliding axis, and a high position closest to the opening.
  • the volume of the housing is maximum.
  • the hollow body comprises an upper part extending between the opening and the base in the lower position, the upper part surrounding the housing and having a continuous inner surface.

  • the hollow body has an outer surface provided with a raceway, substantially parallel to the axis of sliding of the base and cooperating with the actuating surface of the actuating member, when a force is applied on the biasing surface of the actuating member.
  • the force exerted on the biasing surface may be a tangential force, parallel to the sliding axis. It is also possible to press the biasing surface perpendicular to the sliding axis. This improves the attachment between the actuating surface and the hollow body.
  • the axis of rotation of the actuating member may be substantially constant distance from the raceway, so that the actuating surface cooperates constantly with the raceway.
  • the actuating member is mounted floating so that the actuating surface cooperates with the raceway when a force is applied to the biasing surface.
  • the raceway comprises a plurality of reliefs capable of keeping the actuating member stable at different heights of the hollow body.
  • Such reliefs can thus form a plurality of notches.
  • Such notches each include a free edge. These free edges can extend in a common plane parallel to the sliding axis.
  • each relief can be traversed by a respective plane extending substantially perpendicular to the sliding axis.
  • the actuating member may be a ball rolling on rods or splines. The pressure on the biasing surface is transmitted in contact pressure between the ball and the rods, which increases the friction force. In such a case, the ball may be able to hang on the rods without braking the rolling of the ball.
  • the actuating member comprises a wheel and the raceway comprises a rack, the wheel comprising an actuating surface provided with teeth meshing with the rack.
  • the teeth of the wheel improves both the driving of the solicitation surface by a finger and the attachment between the wheel and the rack.
  • the teeth of the rack extend in a plane perpendicular to the axis of sliding.
  • the toothings of the rack have a length of between 30% and 70% of the greatest width of the cross section of the hollow body relative to the sliding axis.
  • the fact of having long hooking teeth reduces the depth of these teeth.
  • the radial size of the drive means is reduced without weakening the wear resistance of the teeth of the wheel or the raceway.

Description

L'invention concerne le domaine des dispositifs de conditionnement étanche et d'application d'un produit, notamment d'un produit cosmétique ou de soin et en particulier d'un produit solidifié en bâton.The invention relates to the field of devices for tight packaging and application of a product, in particular a cosmetic or care product and in particular a solidified product stick.

Par « produit cosmétique », on entend un produit tel que défini dans la Directive 93/35/CEE du Conseil du 14 juin 1993."Cosmetic product" means a product as defined in Council Directive 93/35 / EEC of 14 June 1993.

Dans l'état de la technique, il est connu du document EP 0 504 050 , un applicateur à curseur pour produit solidifié. L'applicateur comprend un corps creux et un socle support pour le produit. Le socle est entraîné en translation par un curseur dépassant du corps creux. Un tel applicateur présente l'inconvénient que l'utilisateur dose difficilement l'effort nécessaire pour faire sortir le produit. Cela est particulièrement gênant pour des produits adhérant fortement à la paroi latérale du corps creux. L'utilisateur est obligé d'exercer un effort de poussée élevé pour décoller le bâton de produit de la paroi latérale. Lorsque le décollement se produit, cet effort important entraîne la sortie quasi complète du produit qui n'est plus guidé par les parois latérales et risque de tomber. Un besoin existe de mieux réguler la sortie du bâton de produit.In the state of the art, it is known from the document EP 0 504 050 , a slider applicator for solidified product. The applicator comprises a hollow body and a support base for the product. The base is driven in translation by a slider protruding from the hollow body. Such an applicator has the disadvantage that the user has difficulty in applying the necessary effort to release the product. This is particularly troublesome for products strongly adhering to the side wall of the hollow body. The user is obliged to exert a high thrust force to unstick the product stick from the side wall. When the detachment occurs, this significant effort causes the almost complete release of the product which is no longer guided by the side walls and may fall. There is a need to better regulate the output of the product stick.

Dans ce domaine technique, le brevet US 1 675 365 décrit un tube pour bâton à lèvres équipé d'un mécanisme de sortie du bâton à lèvres. Le mécanisme comprend une vis sans fin dans l'axe de sortie du bâton à lèvres. Une molette extérieure entraîne en rotation la vis sans fin grâce à un arbre traversant le tube. Il existe un besoin d'améliorer l'étanchéité des dispositifs de conditionnement de produit cosmétique. En effet, certains produits cométiques peuvent comprendre des solvants volatils qui s'évaporent rapidement lorsqu'ils sont disposés par exemple sur les lèvres d'une utilisatrice. Le tube pour bâton à lèvres décrit présente une étanchéité insuffisante pour empêcher les solvants de s'évaporer par le jeu entre la vis sans fin mobile et le tube fixe. Une étanchéité dynamique entre pièces mobile serait complexe à obtenir. De plus, un tel tube ne peut pas être disposé en appui sur le fond du tube en raison de la présence de la molette. Pour faire sortir plus ou moins le bâton à lèvres, l'utilisatrice tient le tube dans une main et la molette dans l'autre. Néanmoins, il est souhaitable de manoeuvrer la sortie du bâton à lèvres avec la même main que celle qui tient le tube afin de laisser libre l'autre main. Cette autre main peut alors servir à tenir un miroir destiné à faciliter l'application de produit.In this technical field, the patent US 1 675 365 discloses a tube for lip stick equipped with an output mechanism of the lip stick. The mechanism comprises a worm in the output shaft of the lip stick. An outer wheel rotates the worm through a shaft passing through the tube. There is a need to improve the sealing of cosmetic product conditioning devices. Indeed, certain cometic products may include volatile solvents which evaporate rapidly when they are arranged for example on the lips of a user. The described lipstick tube has insufficient sealing to prevent solvents from evaporating by the clearance between the auger mobile and the fixed tube. A dynamic seal between moving parts would be complex to obtain. In addition, such a tube can not be placed in abutment on the bottom of the tube because of the presence of the wheel. To make more or less leave the lip stick, the user holds the tube in one hand and the wheel in the other. Nevertheless, it is desirable to manipulate the output of the lip stick with the same hand that holds the tube to let the other hand free. This other hand can then be used to hold a mirror to facilitate product application.

Le brevet US 1 712 840 décrit un tube pour bâton à lèvres équipé d'un autre mécanisme de sortie du bâton à lèvres. Le mécanisme comprend un pignon monté à rotation sur un axe fixe par rapport au tube. Le pignon entraîne en translation un tiroir intérieur, équipé de dents et poussant le bâton à lèvres. L'axe de rotation du pignon traverse le tube. Le pignon est entraîné en rotation par un disque disposé sur un côté du tube carré. L'actionnement manuel du disque est complexe car il est difficile de tenir fermement un tube, tout en appuyant sur le disque de côté sans faire pivoter le tube autour de son axe. De plus, le disque d'entraînement dépasse du tube dans deux directions, à la fois axialement dans l'axe du pignon, et radialement pour être accessible aux doigts de l'utilisatrice. Il existe un besoin d'améliorer l'encombrement et la manoeuvrabilité du mécanisme de sortie du bâton à lèvres.The patent US 1,712,840 discloses a tube for lipstick equipped with another output mechanism of the lip stick. The mechanism comprises a pinion mounted to rotate on a fixed axis relative to the tube. The pinion drives in translation an inner drawer, equipped with teeth and pushing the lip stick. The axis of rotation of the pinion passes through the tube. The pinion is rotated by a disk disposed on one side of the square tube. Manual actuation of the disc is complex because it is difficult to hold a tube firmly while pressing the disc aside without rotating the tube about its axis. In addition, the drive disc protrudes from the tube in two directions, both axially in the axis of the pinion, and radially to be accessible to the wearer's fingers. There is a need to improve the bulkiness and maneuverability of the lip stick output mechanism.

Par ailleurs, le brevet US 2 589 000 décrit un distributeur de beurre. Le distributeur comprend un corps creux ouvert des deux côtés et un socle suiveur pressant le bâton de beurre vers une ouverture du corps. Une roue d'entraînement est montée à rotation dans le socle suiveur et présente une partie moletée d'un diamètre dépassant du corps, et des dentures d'engrenage de petit diamètre coopérant avec des dents du corps du distributeur. L'axe de rotation de la roue traverse une rainure s'étendant le long du corps et notamment à côté de l'endroit où est logé le beurre avant d'être distribué. En particulier, la rainure laissant passer l'axe de rotation de la roue d'entraînement met le beurre en contact direct avec l'extérieur. Un tel distributeur ne convient pas pour conditionner de manière étanche un produit cosmétique ou de soin. De plus, la roue d'entraînement s'étend sur un côté du tube carré, de sorte il est encore difficile de manoeuvrer le dispositif et l'encombrement d'un tel dispositif est important..Moreover, the patent US 2,589,000 describes a butter dispenser. The dispenser comprises a hollow body open on both sides and a follower base pressing the stick of butter towards an opening of the body. A drive wheel is rotatably mounted in the follower base and has a knurled portion of a diameter protruding from the body, and small diameter gear teeth cooperating with teeth of the dispenser body. The axis of rotation of the wheel passes through a groove extending along the body and in particular next to the place where the butter is housed before being distributed. In particular, the groove passing through the axis of rotation of the drive wheel puts the butter in direct contact with the outside. Such a distributor does not not suitable for sealingly packaging a cosmetic or care product. In addition, the drive wheel extends on one side of the square tube, so it is still difficult to maneuver the device and the size of such a device is important.

Le brevet US 3 989 392 décrit un appareil pour distributeur de produit en bâton. Un corps comprend une roue d'engrenage qui entraîne un piston poussant le produit. L'axe de la roue est fixe par rapport au corps. Une telle roue présente l'inconvénient de ne pas démultiplier l'effort de poussée du piston de sorte que ce distributeur ne convient pas pour un produit adhérant à la paroi du distributeur.The patent US 3,989,392 discloses a stick product dispenser apparatus. A body includes a gear wheel that drives a piston pushing the product. The axis of the wheel is fixed relative to the body. Such a wheel has the disadvantage of not multiplying the thrust force of the piston so that the dispenser is not suitable for a product adhering to the wall of the dispenser.

Dans un autre domaine technique, on connaît également par le document US 2 529 037 un ustensile d'écriture comportant un corps creux et un élément glissant portant une mine de crayon. La mine de crayon est déplaçable par l'intermédiaire d'une roue dentée en saillie qui coulisse le long d'une crémaillère située à l'intérieur du corps creux et qui supporte l'élément glissant.In another technical field, it is also known from the document US 2,529,037 a writing implement having a hollow body and a slider bearing a pencil lead. The pencil lead is movable by means of a projecting toothed wheel which slides along a rack located inside the hollow body and which supports the sliding element.

L'invention propose un dispositif de conditionnement et d'application d'un produit cosmétique ou de soin qui remédie à au moins l'un des inconvénients précités.The invention proposes a device for packaging and applying a cosmetic or care product that overcomes at least one of the aforementioned drawbacks.

Un but de l'invention est de proposer un dispositif qui permette de réguler la sortie du produit tout en améliorant la manoeuvrabilité du dispositif pour sortir ou rentrer le produit.An object of the invention is to provide a device that allows to regulate the output of the product while improving the maneuverability of the device for output or return the product.

Selon un mode de réalisation, le dispositif de conditionnement et/ou d'application d'un produit cosmétique ou de soin comprend, un corps creux formant un logement pour le produit, un socle destiné à supporter le produit et des moyens d'entraînement en translation du socle de manière à faire varier le volume du logement. Lesdits moyens d'entraînement comprennent un organe d'actionnement monté mobile en rotation autour d'un axe et déplaçable le long du corps creux de façon solidaire au socle. Ledit organe d'actionnement comporte au moins une portion formant alternativement surface de sollicitation configurée pour être sollicitée par contact manuel et surface d'actionnement configurée pour être en prise le long du corps creux.According to one embodiment, the device for packaging and / or applying a cosmetic or care product comprises, a hollow body forming a housing for the product, a base for supporting the product and means for driving the product. translation of the base so as to vary the volume of the housing. Said drive means comprise an actuator member rotatably mounted about an axis and movable along the hollow body integrally with the base. Said actuating member comprises at least one portion alternately forming a biasing surface configured to be biased by manual contact and an actuating surface configured to be engaged along the hollow body.

La surface d'actionnement est en prise le long d'une surface extérieure du corps creux.The actuating surface is engaged along an outer surface of the hollow body.

Autrement dit, la même portion de l'organe d'actionnement entre alternativement en contact avec le doigt de l'utilisateur ou de l'utilisatrice puis avec le corps creux. Cela a comme effet que la surface de sollicitation est en regard du corps creux. L'utilisateur ou l'utilisatrice peut presser le corps creux et l'organe d'actionnement entre le pouce et le reste de la même main sans que le dispositif ne pivote de côté. En exerçant un mouvement de cisaillement entre le pouce et le reste de la main, l'utilisatrice peut entraîner en rotation l'organe d'actionnement. Au cours de la rotation dudit organe, la portion initialement sollicitée manuellement se déplace pour venir en prise sur la face externe ou surface extérieure du corps creux et ce sur une hauteur donnée dudit corps creux. Cela a comme effet de déplacer l'axe de rotation de l'organe d'actionnement le long du corps creux et d'entraîner le socle en translation. L'effort exercé sur la surface de sollicitation est ainsi démultipliée. Cela permet de réguler la sortie du produit.In other words, the same portion of the actuating member alternately contacts the finger of the user or the user and then with the hollow body. This has the effect that the biasing surface is opposite the hollow body. The user can press the hollow body and the actuator between the thumb and the rest of the same hand without the device pivoting sideways. By exerting a shearing motion between the thumb and the rest of the hand, the user can rotate the actuating member. During the rotation of said body, the portion initially solicited manually moves to engage the outer face or outer surface of the hollow body and on a given height of said hollow body. This has the effect of moving the axis of rotation of the actuating member along the hollow body and to drive the base in translation. The force exerted on the solicitation surface is thus reduced. This helps to regulate the output of the product.

Selon une variante, le corps creux présente une zone intérieure comprenant le logement. Le socle délimite le logement par rapport au reste de la zone intérieure. L'axe de l'organe d'actionnement s'étend hors de la zone intérieure. Autrement dit, l'axe de rotation de l'organe d'actionnement peut s'étendre exclusivement hors du corps creux prévu pour loger le produit cosmétique. Ainsi, l'axe de rotation de l'organe d'actionnement est entièrement décalé par rapport au corps creux supportant le produit cosmétique. Cela a comme effet que l'organe d'actionnement peut se déplacer radialement à l'extérieur du logement du produit selon une direction sensiblement parallèle à l'axe d'extension du produit cosmétique. L'organe d'actionnement ne s'étend pas dans le prolongement du produit. Plus généralement, l'organe d'actionnement n'est pas contenu dans le corps creux. On obtient ainsi un dispositif d'encombrement axial réduit. L'axe de rotation de l'organe d'entraînement est perpendiculaire à l'axe d'extension du produit.According to a variant, the hollow body has an interior zone comprising the housing. The base delimits the housing in relation to the rest of the interior area. The axis of the actuator extends out of the inner zone. In other words, the axis of rotation of the actuating member may extend exclusively outside the hollow body provided for housing the cosmetic product. Thus, the axis of rotation of the actuating member is entirely offset with respect to the hollow body supporting the cosmetic product. This has the effect that the actuator can move radially outside the housing of the product in a direction substantially parallel to the axis of extension of the cosmetic product. The actuating member does not extend in the extension of the product. More generally, the actuating member is not contained in the hollow body. A device of reduced axial size is thus obtained. The axis of rotation of the drive member is perpendicular to the axis of extension of the product.

Le socle peut présenter une surface en contact avec le produit s'étendant sensiblement sur toute la section transversale du logement du produit. Il est également possible, lorsque la compacité du produit est suffisante, que la surface en contact du socle avec le produit ne s'étende pas sur toute la section droite du logement, dès lors que la translation du socle entraîne tout le produit.The base may have a product-contacting surface extending substantially over the entire cross section of the product housing. It is also possible, when the compactness of the product is sufficient, that the surface in contact of the base with the product does not extend over the entire cross section of the housing, since the translation of the base causes all the product.

Selon une variante, le corps creux présente une ouverture de distribution destinée à laisser passer le produit lors du déplacement du socle. L'ouverture peut être en extrémité du logement de sorte que le produit est directement accessible à l'utilisatrice lorsque le socle pousse le produit hors du logement.Alternatively, the hollow body has a dispensing opening for passing the product during the movement of the base. The opening may be at the end of the housing so that the product is directly accessible to the user when the base pushes the product out of the housing.

Avantageusement, le socle est mobile en translation le long d'un axe de coulissement. L'ouverture peut être dans l'alignement du socle dans l'axe de coulissement. Le socle peut se déplacer sur une course, faisant entre 30 % et 100 % de la longueur du logement de produit dans l'axe de coulissement. De préférence, la course peut faire entre 60 % et 98 % de la longueur du logement et notamment entre 80 % et 95 % de cette longueur.Advantageously, the base is movable in translation along a sliding axis. The opening may be in alignment with the base in the sliding axis. The base can move on a stroke, making between 30% and 100% of the length of the product housing in the sliding axis. Preferably, the stroke can be between 60% and 98% of the length of the housing and in particular between 80% and 95% of this length.

Le logement peut présenter une forme allongée le long de l'axe de coulissement dans le cas par exemple de tube de rouge à lèvres. Le logement peut également présenter une forme aplatie présentant une section droite perpendiculaire à l'axe de coulissement plus large que l'épaisseur du logement dans l'axe du coulissement. Ce cas peut convenir pour des distributeurs de produits de faible compacité nécessitant néanmoins d'être poussés en bloc.The housing may have an elongate shape along the axis of sliding in the case for example of lipstick tube. The housing may also have a flattened shape having a cross section perpendicular to the sliding axis wider than the thickness of the housing in the sliding axis. This case may be suitable for distributors of low-compact products that nevertheless need to be pushed together.

Avantageusement, le socle est mobile entre une position basse, la plus éloignée de l'ouverture le long de l'axe de coulissement, et une position haute la plus proche de l'ouverture. Lorsque le socle est en position basse, le volume du logement est maximum.Advantageously, the base is movable between a low position, furthest from the opening along the sliding axis, and a high position closest to the opening. When the base is in the low position, the volume of the housing is maximum.

Avantageusement, le corps creux comprend une partie haute s'étendant entre l'ouverture et le socle en position basse, la partie haute entourant le logement et présentant une surface intérieure continue. Autrement dit, la partie haute ne présente pas d'autres orifices que l'ouverture de distribution du produit et l'emplacement du socle en position basse. En bouchant l'ouverture de distribution et l'espace entre le socle en position basse et le corps creux, il est possible de conserver le produit de manière étanche dans son logement.Advantageously, the hollow body comprises an upper part extending between the opening and the base in the lower position, the upper part surrounding the housing and having a continuous inner surface. In other words, the upper part has no other openings than the dispensing opening of the product and the location of the base in the low position. By plugging the dispensing opening and the space between the base in the low position and the hollow body, it is possible to keep the product sealed in its housing.

Selon un autre mode de réalisation, le corps creux présente une surface extérieure munie d'un chemin de roulement, sensiblement parallèle à l'axe de coulissement du socle et coopérant avec la surface d'actionnement de l'organe d'actionnement, lorsqu'un effort est appliqué sur la surface de sollicitation de l'organe d'actionnement.According to another embodiment, the hollow body has an outer surface provided with a raceway, substantially parallel to the axis of sliding of the base and cooperating with the actuating surface of the actuating member, when a force is applied on the biasing surface of the actuating member.

L'effort exercé sur la surface de sollicitation peut être un effort tangentiel, parallèle à l'axe de coulissement. Il est également possible d'appuyer sur la surface de sollicitation perpendiculairement à l'axe de coulissement. Cela permet d'améliorer l'accrochage entre la surface d'actionnement et le corps creux.The force exerted on the biasing surface may be a tangential force, parallel to the sliding axis. It is also possible to press the biasing surface perpendicular to the sliding axis. This improves the attachment between the actuating surface and the hollow body.

Dans une variante, l'axe de rotation de l'organe d'actionnement peut être à distance sensiblement constante du chemin de roulement, de sorte que la surface d'actionnement coopère constamment avec le chemin de roulement. Dans une autre variante, l'organe d'actionnement est monté flottant de sorte que la surface d'actionnement ne coopère avec le chemin de roulement que lorsqu'un effort est appliqué sur la surface de sollicitation.Alternatively, the axis of rotation of the actuating member may be substantially constant distance from the raceway, so that the actuating surface cooperates constantly with the raceway. In another variant, the actuating member is mounted floating so that the actuating surface cooperates with the raceway when a force is applied to the biasing surface.

Avantageusement, le chemin de roulement comporte une pluralité de reliefs aptes à maintenir l'organe d'actionnement stable à différentes hauteurs du corps creux. De tels reliefs peuvent ainsi former une pluralité de crans. De tels crans comprennent chacun un bord libre. Ces bords libres peuvent s'étendre selon un plan commun parallèle à l'axe de coulissement. Autrement dit, chaque relief peut être traversé par un plan respectif s'étendant sensiblement perpendiculairement à l'axe de coulissement. Par exemple, l'organe d'actionnement peut être une bille roulant sur des joncs ou cannelures. La pression sur la surface de sollicitation est transmise en pression de contact entre la bille et les joncs, ce qui augmente l'effort de frottement. Dans un tel cas, la bille peut être apte à accrocher aux joncs sans freiner le roulement de la bille.Advantageously, the raceway comprises a plurality of reliefs capable of keeping the actuating member stable at different heights of the hollow body. Such reliefs can thus form a plurality of notches. Such notches each include a free edge. These free edges can extend in a common plane parallel to the sliding axis. In other words, each relief can be traversed by a respective plane extending substantially perpendicular to the sliding axis. For example, the actuating member may be a ball rolling on rods or splines. The pressure on the biasing surface is transmitted in contact pressure between the ball and the rods, which increases the friction force. In such a case, the ball may be able to hang on the rods without braking the rolling of the ball.

Selon un autre mode de réalisation, l'organe d'actionnement comprend une molette et le chemin de roulement comprend une crémaillère, la molette comprenant une surface d'actionnement munie de dentures engrenant avec la crémaillère. Les dentures de la molette améliorent à la fois l'entraînement de la surface de sollicitation par un doigt et l'accrochage entre la molette et la crémaillère.According to another embodiment, the actuating member comprises a wheel and the raceway comprises a rack, the wheel comprising an actuating surface provided with teeth meshing with the rack. The teeth of the wheel improves both the driving of the solicitation surface by a finger and the attachment between the wheel and the rack.

Avantageusement, les dentures de la crémaillère s'étendent dans un plan perpendiculaire à l'axe de coulissement.Advantageously, the teeth of the rack extend in a plane perpendicular to the axis of sliding.

Avantageusement, les dentures de la crémaillère présentent une longueur comprise entre 30 % et 70 % de la plus grande largeur de la section transversale du corps creux par rapport à l'axe de coulissement. Le fait d'avoir des dentures d'accrochage de grande longueur permet de réduire la profondeur de ces dentures. L'encombrement radial des moyens d'entraînement est réduit sans fragiliser la résistance à l'usure des dentures de la molette ou du chemin de roulement.Advantageously, the toothings of the rack have a length of between 30% and 70% of the greatest width of the cross section of the hollow body relative to the sliding axis. The fact of having long hooking teeth reduces the depth of these teeth. The radial size of the drive means is reduced without weakening the wear resistance of the teeth of the wheel or the raceway.

De telles dentures peuvent s'étendre sur au moins 30% de la hauteur du corps creux et de préférence sur plus de 40% de cette hauteur.Such teeth may extend over at least 30% of the height of the hollow body and preferably over more than 40% of this height.

Selon une variante, le chemin de roulement présente une portion concave et l'organe d'actionnement présente une portion complémentaire convexe ou inversement. Par exemple, le corps creux peut présenter une section perpendiculaire à l'axe de coulissement en forme de haricot. Le chemin de roulement est ménagé le long du flanc concave du corps creux et l'organe d'actionnement présente une forme complémentaire convexe. L'enveloppe entourant la section du corps creux et de l'organe d'actionnement peut être sensiblement elliptique. Cela permet de rendre l'ensemble facilement logeable dans un boîtier.According to a variant, the race has a concave portion and the actuator has a convex complementary portion or vice versa. For example, the hollow body may have a section perpendicular to the bean-shaped sliding axis. The raceway is formed along the concave side of the hollow body and the actuating member has a complementary convex shape. The envelope surrounding the section of the hollow body and the actuating member may be substantially elliptical. This makes the assembly easily housed in a housing.

Dans un autre exemple, le corps creux peut présenter une section transversale elliptique. L'organe d'actionnement peut tourner autour d'un axe dans le plan de ladite section droite et présenter une forme de diamètre plus réduit dans sa partie médiane. Cela permet à un doigt de coopérer plus largement avec la surface de sollicitation.In another example, the hollow body may have an elliptical cross section. The actuating member is rotatable about an axis in the plane of said straight section and has a smaller diameter shape in its middle portion. This allows a finger to cooperate more widely with the biasing surface.

Selon un autre mode de réalisation, les moyens d'entraînement comprennent un bras de liaison reliant l'organe d'actionnement au socle de manière à faire varier le volume du logement entre un volume maximum et un volume minimum. Le corps creux présente une ouverture de liaison s'étendant hors du logement de volume maximum et traversée par le bras de liaison. Dans ce mode de réalisation, le fait que le bras de liaison traverse le corps creux en dehors du logement du volume maximum permet au bras de contourner le logement de volume maximum sans le traverser. Cela permet au logement de présenter des parois latérales étanches.According to another embodiment, the drive means comprise a connecting arm connecting the actuating member to the base so as to vary the volume of the housing between a maximum volume and a minimum volume. The hollow body has a connecting opening extending out of the housing of maximum volume and traversed by the connecting arm. In this embodiment, the fact that the connecting arm passes through the hollow body outside the housing of the maximum volume allows the arm to bypass the volume housing. maximum without crossing it. This allows the housing to have side walls sealed.

Selon une variante, le bras de liaison présente une forme en U et comprend une branche intérieure située dans la zone intérieure du corps creux et reliée au socle. Une branche extérieure s'étend parallèlement à l'extérieur du corps creux et est reliée à la branche intérieure par une entretoise de liaison située axialement à distance du socle. Grâce à la forme en U, le bras de liaison entraîne le socle en contournant le logement maximal du produit. L'extrémité libre de la branche extérieure peut être située sensiblement à la hauteur du socle. L'extrémité libre de la branche extérieure peut donner une indication du niveau d'utilisation du produit.According to a variant, the link arm has a U-shape and comprises an inner branch located in the inner region of the hollow body and connected to the base. An outer branch extends parallel to the outside of the hollow body and is connected to the inner branch by a connecting spacer located axially away from the base. Thanks to the U-shape, the link arm drives the base around the maximum housing of the product. The free end of the outer branch can be located substantially at the height of the base. The free end of the outer branch can give an indication of the level of use of the product.

L'extrémité libre du bras de liaison peut être équipée de l'organe d'actionnement. Le dispositif peut être posé à plat dans la main. Lorsque le pouce est posé sur la surface de sollicitation de l'organe d'actionnement, l'effort s'exerce sensiblement au milieu du dispositif. Cela améliore la stabilité de la manoeuvre.The free end of the connecting arm can be equipped with the actuating member. The device can be placed flat in the hand. When the thumb is placed on the biasing surface of the actuating member, the force is exerted substantially in the middle of the device. This improves the stability of the maneuver.

Selon une variante, la branche extérieure présente une partie sensiblement plate. Le corps creux présente des rails de guidage en translation axiale de ladite partie plate. Grâce aux rails de guidage, il suffit à l'utilisatrice de tirer l'extrémité libre de la branche extérieure par l'organe d'actionnement pour que le socle suive le même déplacement.According to one variant, the outer branch has a substantially flat portion. The hollow body has guide rails in axial translation of said flat portion. Thanks to the guide rails, it is sufficient for the user to pull the free end of the outer branch by the actuator so that the base follows the same movement.

Avantageusement, le corps creux est de forme tubulaire présentant une paroi latérale. L'ouverture de liaison comprend une rainure de coulissement ménagée dans la paroi latérale et laissant passer l'entretoise de liaison.Advantageously, the hollow body is of tubular shape having a side wall. The connection opening comprises a sliding groove formed in the side wall and allowing the connecting spacer to pass.

Avantageusement, la rainure s'étend sur une hauteur du corps creux telle qu'elle ne vient pas en regard du produit.Advantageously, the groove extends over a height of the hollow body such that it does not come opposite the product.

Avantageusement, la crémaillère s'étend dans le prolongement de la rainure de coulissement. Cela permet d'augmenter la longueur en prise des dentures. Cela permet de réduire l'encombrement des moyens d'entraînement.Advantageously, the rack extends in the extension of the sliding groove. This makes it possible to increase the length in engagement of the teeth. This reduces the size of the drive means.

Selon une variante, l'organe d'actionnement est monté en rotation par deux portées situées de part et d'autre, le long de l'axe de l'organe d'actionnement, de la surface de sollicitation.According to a variant, the actuating member is rotatably mounted by two bearing surfaces located on either side, along the axis of the actuating member, of the biasing surface.

Par exemple, l'organe d'actionnement peut présenter deux tétons latéraux reçus dans deux encoches latérales du bras de liaison. Cela permet d'équilibrer les efforts de traction exercés sur le bras de liaison.For example, the actuating member may have two lateral pins received in two lateral notches of the link arm. This balances the traction forces exerted on the link arm.

Dans un autre exemple, l'organe d'actionnement présente deux orifices latéraux coopérant avec deux doigts du bras de liaison.In another example, the actuating member has two lateral orifices cooperating with two fingers of the connecting arm.

Dans encore un autre exemple, l'organe d'actionnement présente une forme symétrique par rapport à un plan médian telle qu'une bille, une forme ovoïde, de diabolo, de tonneau ou de cylindre et en particulier de cylindre droit. Les deux portées latérales peuvent coopérer directement avec la forme symétrique.In yet another example, the actuating member has a shape symmetrical with respect to a median plane such as a ball, an ovoid shape, diabolo, barrel or cylinder and in particular right cylinder. The two lateral surfaces can cooperate directly with the symmetrical shape.

Selon un autre mode de réalisation le dispositif comprend un boîtier muni d'un couvercle fermable sur une embase. Le boîtier présente, lorsque le couvercle est fermé, un espace intérieur de boîtier étanche, contenant le corps creux et les moyens d'entraînement.According to another embodiment the device comprises a housing provided with a closable lid on a base. The housing has, when the lid is closed, a sealed housing interior space, containing the hollow body and the drive means.

Avantageusement, l'extrémité libre de la branche extérieure du bras de liaison fait saillie de l'embase. L'organe d'actionnement est monté libre en rotation dans ladite extrémité libre. Cela permet de manipuler l'ensemble comprenant l'embase, le corps creux et les moyens d'entraînement et de refermer le couvercle lorsque le produit est rentré dans son logement.Advantageously, the free end of the outer branch of the connecting arm protrudes from the base. The actuating member is rotatably mounted in said free end. This allows to manipulate the assembly comprising the base, the hollow body and the drive means and to close the lid when the product is returned to its housing.

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

Avantageusement, le stick de produit peut être une composition solide en particulier délitable à sec. Par délitable à sec, on désigne une composition apte, à température ambiante, à former un dépôt adhérent et gainant sur un substrat, notamment des fibres kératiniques, et plus particulièrement des cils, lorsqu'ils sont respectivement mis en contact l'un avec l'autre, sans nécessiter de préparation préalable, et en l'occurrence sans nécessité de mise en contact préalable de la composition avec une phase aqueuse. De tels produits délitables à sec s'opposent par exemple aux mascaras en pains qui sont délitables à l'eau et doivent être au préalable solubilisés partiellement pour être appliqués sur les fibres kératiniques et former un dépôt adhérent et gainant.Advantageously, the product stick may be a solid composition, in particular dry-crackable. Delivable dry means a composition able, at room temperature, to form an adherent deposit and sheathing on a substrate, especially keratinous fibers, and more particularly eyelashes, when respectively contacted with each other, without the need for prior preparation, and in this case without the need for prior contact of the composition with an aqueous phase. Such dry-breaking products are, for example, opposed to bread mascaras which are deleterious to water and must first be partially solubilized so as to be applied to the keratinous fibers and form an adherent and sheathing deposit.

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

La méthode utilisée pour déterminer la dureté d'une composition cosmétique est celle dite « du fil à couper le beurre ». A cet effet, on prépare un stick de ladite composition dont la dureté doit être déterminée. Le stick est obtenu par coulage d'une composition dans un moule aluminium placé 45 minutes à -28°C, plus démoulée et conditionnée dans un article de conditionnement, en particulier un stylo, et conservée ensuite à une température de 20°C pendant 24 heures précédent la mesure. Un fil rigide de diamètre 250 µm en tungstène est avancé relativement au stick à une vitesse de 100 mm/mn de manière à couper transversalement le stick à l'aide du fil. La dureté mesurée correspond à la force maximale de cisaillement exercée par le cil sur le stick à 20°C.The method used to determine the hardness of a cosmetic composition is that known as "butter-cutting thread". For this purpose, a stick of said composition is prepared, the hardness of which must be determined. The stick is obtained by casting a composition in an aluminum mold placed for 45 minutes at -28 ° C., removed from the mold and packaged in a packaging article, in particular a pen, and then stored at a temperature of 20 ° C. for 24 hours. hours before the measurement. A rigid wire of diameter 250 microns in tungsten is advanced relative to the stick at a speed of 100 mm / min so as to cut the stick transversely using the wire. The hardness measured corresponds to the maximum shear force exerted by the eyelash on the stick at 20 ° C.

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

Toutefois, les produits conditionnés et appliqués par le dispositif peuvent ne pas être autoportants. Le dispositif peut être utilisé pour amener une quantité de produit à affleurer l'ouverture du dispositif et à appliquer sur d'autres portions corporelles que les cils ou les lèvres.However, products packaged and applied by the device may not be self-supporting. The device can be used to cause a quantity of product to flush with the opening of the device and to apply to other body parts than eyelashes or lips.

Comme illustré en figure 1, le dispositif de conditionnement et d'application de produit cosmétique ou de soin comprend un boîtier 1 comportant une embase 2 sur laquelle est monté un couvercle 3. Le boîtier 1 présente la forme d'un cylindre dont la génératrice correspond à un axe de translation X du couvercle 3 relativement à l'embase 2. En particulier, une section transversale à l'axe X du boîtier présente un contour convexe vers l'extérieur, par exemple une forme ovoïde et en particulier une section transversale elliptique de grand axe Y qui est perpendiculaire à l'axe X.As illustrated in figure 1 , the device for packaging and applying cosmetic or care product comprises a housing 1 having a base 2 on which is mounted a cover 3. The housing 1 has the shape of a cylinder whose generator corresponds to a translation axis X of the cover 3 relative to the base 2. In particular, a cross section to the X axis of the housing has a contour convex outwards, for example an ovoid shape and particular an elliptical cross section of large Y axis which is perpendicular to the X axis.

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

Comme illustré en figure 2, le boîtier 1 contient des moyens d'application 4 d'un produit 28 qui sera illustré dans les figures 4 à 8. Le boîtier 1 permet le conditionnement et la distribution du produit 28, notamment d'un produit cosmétique, se présentant sous la forme d'un stick ou raisin et s'étendant selon l'axe X. Ces moyens d'application 4 comprennent un corps creux 5, un piston 6 composé d'un socle 7 et d'un pied de socle 8, d'une molette 9 et d'une plaque de guidage 10.As illustrated in figure 2 , the housing 1 contains application means 4 of a product 28 which will be illustrated in the Figures 4 to 8 . The casing 1 allows the packaging and distribution of the product 28, in particular a cosmetic product, in the form of a stick or grape and extending along the axis X. These application means 4 comprise a body hollow 5, a piston 6 composed of a base 7 and a pedestal base 8, a wheel 9 and a guide plate 10.

Le corps creux 5 présente une forme cylindrique le long de l'axe X et ayant une section transversale en forme de haricot, c'est-à-dire une section transversale allongée selon l'axe Y. Ainsi, ce corps creux 5 peut présenter un côté ou une face 11 convexe et un côté ou une face 12 concave. Le corps creux 5 présente une forme tubulaire présentant une ouverture 50 de distribution du produit 28, une partie haute 13 et une partie basse 14. Le côté concave 12 présente, sur une surface extérieure, en partie haute 13 des reliefs, et en particulier une crémaillère 15, et en partie basse 14 une rainure 16. Les dentures 15a de la crémaillère 15 peuvent présenter une longueur comprise entre 30% et 70% de la plus grande largeur de la section transversale du corps creux par rapport à l'axe de coulissement. Les dentures 15a peuvent s'étendre sur au moins 30% de la hauteur du corps creux et de préférence sur plus de 40% de cette hauteur. La rainure peut être alignée dans le prolongement de la crémaillère 15 parallèlement à l'axe X situé selon l'axe Y, sensiblement au milieu du côté concave 12.The hollow body 5 has a cylindrical shape along the X axis and having a cross-section in the form of a bean, that is to say an elongated cross section along the Y axis. Thus, this hollow body 5 can have a convex side or face 11 and a concave side or face 12. The hollow body 5 has a tubular shape having an opening 50 for dispensing the product 28, an upper part 13 and a lower part 14. The concave side 12 has, on an outer surface, in the upper part 13 of the reliefs, and in particular a rack 15, and in the lower part 14 a groove 16. The teeth 15a of the rack 15 may have a length of between 30% and 70% of the largest width of the cross section of the hollow body relative to the axis of sliding . The teeth 15a may extend over at least 30% of the height of the hollow body and preferably over more than 40% of this height. The groove may be aligned in the extension of the rack 15 parallel to the X axis located along the Y axis, substantially in the middle of the concave side 12.

Le corps creux 5 présente un rail de guidage latéral droit 19a et un rail de guidage latéral gauche 19b situés de part et d'autre de la crémaillère 15 et parallèles à l'axe X.The hollow body 5 has a right lateral guide rail 19a and a left lateral guide rail 19b located on either side of the rack 15 and parallel to the axis X.

La plaque de guidage 10 présente une arête latérale droite 20a et une arête latérale gauche 20b destinées à coulisser respectivement dans le rail de guidage droit 19a et le rail de guidage gauche 19b parallèlement à l'axe X. L'axe X correspond au coulissement du piston 6 entraînant le produit 28 et est également appelé axe de coulissement du socle 7.The guide plate 10 has a right lateral edge 20a and a left lateral edge 20b intended to slide respectively in the right guide rail 19a and the left guide rail 19b parallel to the axis X. The axis X corresponds to the sliding of the piston 6 driving the product 28 and is also called sliding axis of the base 7.

La molette 9 est destinée à être montée en rotation en partie haute de la plaque de guidage 10 selon un axe de rotation 17 parallèle à l'axe Y.The wheel 9 is intended to be mounted in rotation in the upper part of the guide plate 10 along an axis of rotation 17 parallel to the axis Y.

La molette 9 comprend une partie ovoïde centrale 21 de révolution et munie de dentures longitudinales 21a sensiblement parallèle à l'axe de rotation 17 de la molette 9. La molette 9 comprend un téton latéral droit 18a et un téton latéral gauche 18b situés de part et d'autre de la partie centrale 21 le long de l'axe de rotation 17. Dans un tel mode de réalisation, la molette présente sur une portion ou surface convexe apte à coopérer avec une portion ou surface concave extérieure du corps creux. Selon une caractéristique avantageuse et comme illustrée sur la figure 4, l'axe de rotation 17 de la molette 9 peut s'étendre exclusivement hors du corps creux 5. Autrement dit, lorsque le dispositif est projeté sur un plan orthogonal à l'axe de coulissement X, l'axe de rotation 17 de la molette 9 et le corps creux 5 ne se superposent pas.The wheel 9 comprises a central ovoid portion 21 of revolution and provided with longitudinal teeth 21a substantially parallel to the axis of rotation 17 of the wheel 9. The wheel 9 comprises a right side stud 18a and a left side stud 18b located on the side and else of the central portion 21 along the axis of rotation 17. In such an embodiment, the wheel has a convex portion or surface capable of cooperating with a portion or outer concave surface of the hollow body. According to an advantageous characteristic and as illustrated on the figure 4 , the axis of rotation 17 of the wheel 9 can extend exclusively outside the hollow body 5. In other words, when the device is projected on a plane orthogonal to the sliding axis X, the axis of rotation 17 of the wheel 9 and the hollow body 5 do not overlap.

La partie haute de la plaque de guidage 10 présente un évidement central 22 entre une patte de fixation droite 23a et une patte de fixation gauche 23b. Les pattes de fixation droite 23a et gauche 23b présentent chacune un palier 31 en forme de U ouvert dans une direction perpendiculaire à la plaque de guidage 10 et destiné à recevoir les tétons latéraux droit 18a et gauche 18b de la molette 9. En variante, la molette 9 pourrait être traversée par un arbre de rotation monté sur lesdites pattes de fixation droite et gauche 23a, 23b.The upper portion of the guide plate 10 has a central recess 22 between a right bracket 23a and a left bracket 23b. The right-hand 23a and left-23b mounting tabs each have a U-shaped bearing 31 open in a direction perpendicular to the guide plate 10 and intended to receive the right and left-hand lateral studs 18a of the wheel 9. In a variant, the wheel 9 could be traversed by a rotation shaft mounted on said right and left brackets 23a, 23b.

Lorsque la molette 9 est fixée dans les pattes de fixation 23a, 23b, la partie centrale 21 de la molette 9 occupe l'évidement central 22 de la plaque 10 et fait saillie des deux côtés de la plaque de guidage 10. L'ensemble de la plaque de guidage 10 et de la molette 9 peut être introduit dans les rails de guidage 19a et 19b du corps creux 5. Les dentures 21a de la molette 9 coopèrent avec la crémaillère 15 par une surface d'actionnement 40 de la molette 9. La molette présente une surface de sollicitation 39, opposée à la surface d'actionnement 40, et dépassant de la plaque de guidage 10 de sorte qu'un doigt glissant le long de la plaque de guidage 10 peut appuyer sur la surface de sollicitation 39 pour entrainer la molette 9 en rotation.When the wheel 9 is fixed in the fixing lugs 23a, 23b, the central portion 21 of the wheel 9 occupies the central recess 22 of the 10 and protrudes from both sides of the guide plate 10. The assembly of the guide plate 10 and the knob 9 can be introduced into the guide rails 19a and 19b of the hollow body 5. The teeth 21a of the wheel 9 cooperate with the rack 15 by an actuating surface 40 of the wheel 9. The wheel has a biasing surface 39, opposite to the actuating surface 40, and protruding from the guide plate 10 so that a sliding finger along the guide plate 10 can press the biasing surface 39 to cause the wheel 9 rotating.

Le corps creux 5 est de forme tubulaire et présente une zone intérieure 45 s'étendant le long de l'axe X et débouchant à l'extrémité supérieure du corps creux 5 par une ouverture 50 destinée à la distribution du produit 28.The hollow body 5 is tubular in shape and has an inner zone 45 extending along the axis X and opening at the upper end of the hollow body 5 through an opening 50 intended for dispensing the product 28.

Le corps creux 5 présente une zone intérieure 45 comprenant le logement 46, le socle 7 délimitant le logement 46 par rapport au reste de la zone intérieure, l'axe 17 de l'organe d'actionnement s'étendant hors de la zone intérieure 45.The hollow body 5 has an inner zone 45 comprising the housing 46, the base 7 delimiting the housing 46 relative to the remainder of the inner zone, the axis 17 of the actuating member extending out of the inner zone 45 .

Le socle 7 présente une lèvre supérieure souple d'étanchéité 24 et une lèvre inférieure souple de guidage 25 s'étendant l'une et l'autre sur le pourtour du socle 7 et destinés à épouser une surface intérieure 26 de la zone intérieure 45. Le socle 7 présente un côté supérieur 27 destiné à recevoir le produit 28. Le côté supérieur 27 présente une forme de cuvette délimitée par la lèvre supérieure 24, un fond plat 29 et une série de tétons d'amarrage 30 faisant saillie du fond plat 29 vers le produit 28.The base 7 has a flexible upper sealing lip 24 and a flexible lower guide lip 25 extending both around the periphery of the base 7 and intended to fit an inner surface 26 of the inner zone 45. The base 7 has an upper side 27 for receiving the product 28. The upper side 27 has a cup shape delimited by the upper lip 24, a flat bottom 29 and a series of mooring nipples 30 projecting from the flat bottom 29 to the product 28.

La partie de la zone intérieure située au-dessus du socle 7 du piston 6 constitue un logement 46 du produit 28. Le volume du logement 46 varie avec la position du piston 6 dans la zone intérieure 45.The part of the inner zone situated above the base 7 of the piston 6 constitutes a housing 46 of the product 28. The volume of the housing 46 varies with the position of the piston 6 in the inner zone 45.

Le pied de socle 8 s'étend du côté opposé au côté supérieur 27, parallèlement à la plaque de guidage 10 et présente une nervure de renfort 32.The base leg 8 extends on the opposite side to the upper side 27, parallel to the guide plate 10 and has a reinforcing rib 32.

Comme illustré sur la figure 3, les moyens d'application 4 sont introduits dans l'embase 2. L'embase 2 présente des moyens d'encliquetage 35 du couvercle 3 comprenant une jupe 36 faisant saillie d'un épaulement 37 et s'étendant sur un pourtour intérieur de l'embase 2. Un bourrelet d'encliquetage 38 s'étend tout autour de la jupe 36 parallèlement à l'épaulement 37.As illustrated on the figure 3 , the application means 4 are introduced into the base 2. The base 2 has latching means 35 of the cover 3 comprising a skirt 36 projecting from a shoulder 37 and extending on an inner periphery of the base 2. A snap-fitting bead 38 extends all the way around the skirt 36 parallel to the shoulder 37.

Les moyens d'application 4 sont représentés en position basse sur la figure 3. L'axe de rotation 17 de la molette 9 est sensiblement au milieu du corps creux 5. Dans la position basse, la molette 9 est située au-dessus de la jupe 36 de l'embase 2. Dans ce mode de réalisation, la surface de sollicitation 39 de la molette 9 s'étend sur une largeur supérieure à celle de la crémaillère 15. Ainsi, le doigt de l'utilisatrice entraîne les dentures 21 a de la molette 9 sur toute la longueur de la molette. Seule la partie centrale des dentures 21a de la molette 9 sert de surface d'actionnement 40 coopérant avec les dentures 15a de la crémaillère 15.The application means 4 are represented in a low position on the figure 3 . The axis of rotation 17 of the wheel 9 is substantially in the middle of the hollow body 5. In the low position, the wheel 9 is located above the skirt 36 of the base 2. In this embodiment, the surface the biasing wheel 39 of the wheel 9 extends over a width greater than that of the rack 15. Thus, the finger of the user drives the teeth 21 a of the wheel 9 over the entire length of the wheel. Only the central portion of the teeth 21a of the wheel 9 serves as an actuating surface 40 cooperating with the teeth 15a of the rack 15.

Comme illustré sur la figure 4, le produit 28 occupe le logement 46 en partie haute 13 du corps creux 5. La partie ovoïde centrale 21 de la molette 9 dépasse radialement de la plaque de guidage 10 sans toutefois dépasser radialement la jupe 36 de sorte que le couvercle 3 ajusté à la jupe 36 entoure l'ensemble des moyens d'application 4 et présente un profil intérieur et extérieur elliptique.As illustrated on the figure 4 , the product 28 occupies the housing 46 in the upper part 13 of the hollow body 5. The central ovoid portion 21 of the wheel 9 protrudes radially from the guide plate 10 without radially exceeding the skirt 36 so that the lid 3 is adjusted to the skirt 36 surrounds all of the application means 4 and has an elliptical inner and outer profile.

Comme illustré sur les figures 5 et 6, le boîtier 1 comprend des moyens d'étanchéité 41 entre l'embase 2 et le couvercle 3. L'épaulement 37 de l'embase 2 présente une rainure circulaire 42 s'étendant au pied de la jupe 36. Le rebord inférieur du couvercle 3 présente une lèvre intérieure 43 destinée à pénétrer en force dans la rainure circulaire 42. Le couvercle 3 présente un bourrelet intérieur 44 destiné à coopérer avec le bourrelet d'encliquetage 38 de l'embase 2. La déformation élastique du couvercle 3 permet au bourrelet 44 de se dilater autour du bourrelet d'encliquetage 38 et à dépasser axialement ledit bourrelet 38 de manière qu'un épaulement 37a du couvercle 3 soit plaqué contre l'épaulement 37 de l'embase 2.As illustrated on Figures 5 and 6 , the housing 1 comprises sealing means 41 between the base 2 and the cover 3. The shoulder 37 of the base 2 has a circular groove 42 extending at the bottom of the skirt 36. The lower rim of the cover 3 has an inner lip 43 intended to penetrate force into the circular groove 42. The cover 3 has an inner bead 44 intended to cooperate with the snap-fitting bead 38 of the base 2. The elastic deformation of the cover 3 allows the bead 44 to expand around the ratchet bead 38 and to axially exceed said bead 38 so that a shoulder 37a of the cover 3 is pressed against the shoulder 37 of the base 2.

La zone intérieure 45 présente un épaulement intérieur 54. La partie de la zone intérieure 45 correspondant à la partie basse 14 du corps creux 5 présente une section droite plus réduite que le socle 7.The inner zone 45 has an inner shoulder 54. The portion of the inner zone 45 corresponding to the lower portion 14 of the hollow body 5 has a smaller cross-section than the base 7.

Un ergot d'entraînement 47 s'étend perpendiculairement à la plaque de guidage 10 et forme avec la plaque de guidage 10 un ensemble monobloc. L'ergot d'entraînement 47 traverse la rainure 16 ainsi qu'un orifice 48 du pied de socle 8. L'ergot d'entraînement 47 constitue une entretoise 49 entre la plaque de guidage 10 et le pied de socle 8 sensiblement parallèles. L'ensemble comprenant la molette 9, la plaque de guidage 10 et le piston 6, constitue des moyens d'entraînement 51 du produit 28.A driving pin 47 extends perpendicularly to the guide plate 10 and forms with the guide plate 10 a set piece. The driving pin 47 passes through the groove 16 and an orifice 48 of the pedestal base 8. The driving pin 47 is a spacer 49 between the guide plate 10 and the base foot 8 substantially parallel. The assembly comprising the wheel 9, the guide plate 10 and the piston 6 constitutes driving means 51 of the product 28.

On va maintenant décrire le mode d'assemblage du dispositif. Le piston 6 est introduit dans l'ouverture 50 en commençant par le pied de socle 8, jusqu'à ce que la lèvre inférieure 25 du socle 7 soit en appui sur l'épaulement intérieur 54 du corps creux 5. Le piston 6 occupe alors une position extrême d'assemblage qui est plus basse que la position basse de fonctionnement normal du dispositif. La molette 9 et la plaque de guidage 10 sont assemblées et l'ergot d'entraînement 47 est disposé en face de l'orifice 48 du pied de socle. Dans cette position extrême d'assemblage, les arêtes 20a et 20b de la plaque de guidage 10 ne sont pas encore introduites dans les rails de guidage 19a et 19b du corps creux 5.We will now describe the method of assembly of the device. The piston 6 is introduced into the opening 50, starting with the base leg 8, until the lower lip 25 of the base 7 bears against the inner shoulder 54 of the hollow body 5. The piston 6 then occupies an extreme assembly position which is lower than the normal operating low position of the device. The wheel 9 and the guide plate 10 are assembled and the driving pin 47 is disposed opposite the orifice 48 of the base foot. In this extreme assembly position, the edges 20a and 20b of the guide plate 10 are not yet introduced into the guide rails 19a and 19b of the hollow body 5.

Le moyen d'entraînement 51 est ensuite déplacé de la position extrême d'assemblage à la position basse de fonctionnement. Dans cette position basse de fonctionnement, la molette 9 est en prise avec le début de la crémaillère 5 et les arêtes 20a et 20b sont introduites dans les rails de guidage 19a et 19b. L'extrémité inférieure 55 de la plaque de guidage 10 affleure avec l'extrémité inférieure 55a du corps creux 5.The drive means 51 is then moved from the end assembly position to the low operating position. In this low operating position, the wheel 9 is engaged with the beginning of the rack 5 and the edges 20a and 20b are introduced into the guide rails 19a and 19b. The lower end 55 of the guide plate 10 is flush with the lower end 55a of the hollow body 5.

Le moyen d'entraînement 51 et le corps creux 5 sont alors introduits dans l'embase 2. Le produit 28 peut être introduit dans le dispositif par coulage à chaud lorsque le moyen d'entraînement 51 est dans la position basse. L'embase 2 empêche l'extrémité inférieure 55 de la plaque de guidage 10 de descendre plus bas et maintien la cohésion du moyen d'entraînement 51.The drive means 51 and the hollow body 5 are then introduced into the base 2. The product 28 can be introduced into the device by hot casting when the drive means 51 is in the low position. The base 2 prevents the lower end 55 of the guide plate 10 from descending lower and maintains the cohesion of the drive means 51.

On va maintenant, à l'aide des figures 7 et 8, décrire le fonctionnement du dispositif. Le moyen d'entraînement 51 présente une forme en U dans lequel le pied de socle 8 constitue une branche intérieure 52, la plaque de guidage 10 constitue une branche extérieure 53 et l'entretoise 49 constitue la base de la forme en U. La partie supérieure de la plaque de guidage 10 constitue l'extrémité libre de la branche extérieure 53. Lorsque l'opérateur fait glisser son pouce sur la surface de sollicitation 39 de la molette 9, celle-ci roule sur la crémaillère 15 prévue sur la surface extérieure du corps creux 5. Une portion de la molette 9 est successivement, ou de manière alternative, sollicitée par le pouce de l'opérateur, puis engrène avec la crémaillère 15. Les tétons latéraux 18a et 18b de la molette 9 tirent les pattes de fixation 23a et 23b de la plaque de guidage 10. Ainsi, l'ensemble du moyen d'entraînement 51 et du produit 28 se déplace en bloc. Autrement dit, la rotation de la molette 9 entraîne son déplacement le long d'une face extérieure du corps creux 5 sur une hauteur donnée. Ce déplacement entraîne le déplacement solidaire du socle 7. Un tel déplacement peut se faire en direction de l'ouverture 50 de distribution de produit 28 afin d'extraire du corps creux 5 une quantité de produit 28 à s'appliquer ou en éloignement de ladite ouverture 50 afin de rentrer ledit produit 28 dans le corps creux 5. Le socle 7 peut se déplacer en contact de coulissement étanche contre la paroi interne du corps creux 5. La molette 9 permet que l'effort tangentiel d'entraînement de la surface de sollicitation 39 soit moitié moindre de l'effort nécessaire pour entraîner le moyen d'entraînement 51 et le produit 28.We will now, with the help of Figures 7 and 8 , describe the operation of the device. The drive means 51 has a U-shape in which the base leg 8 constitutes an inner branch 52, the guide plate 10 constitutes an outer branch 53 and the spacer 49 forms the base of the U-shape. upper of the guide plate 10 constitutes the free end of the outer branch 53. When the operator slides his thumb on the biasing surface 39 of the wheel 9, it rolls on the rack 15 provided on the outer surface of the hollow body 5. A portion of the wheel 9 is successively, or alternatively, biased by the thumb of the operator, then meshes with the rack 15. The lateral studs 18a and 18b of the wheel 9 pull the fastening tabs 23a and 23b of the guide plate 10. Thus, all of the drive means 51 and the product 28 moves in a block. In other words, the rotation of the wheel 9 causes its movement along an outer face of the hollow body 5 to a given height. This movement leads to the displacement of the base 7. Such a displacement can be made in the direction of the product dispensing aperture 28 in order to extract from the hollow body 5 a quantity of product 28 to be applied to or away from said opening 50 to return said product 28 in the hollow body 5. The base 7 can move in sealing contact against the inner wall of the hollow body 5. The wheel 9 allows the tangential force of the drive surface solicitation 39 half the effort required to drive the drive 51 and the product 28.

Lorsque les lèvres supérieures 24 affleurent l'ouverture de distribution 50, la molette 9 arrive à l'extrémité haute de la crémaillère 15 et l'ergot d'entraînement 47 arrive en butée au fond de la rainure 16. Cette position est la position la plus haute possible de fonctionnement du dispositif.When the upper lips 24 are flush with the dispensing opening 50, the wheel 9 arrives at the upper end of the rack 15 and the driving pin 47 comes into abutment with the bottom of the groove 16. This position is the position highest possible operating device.

Le deuxième mode de réalisation illustré en figure 9, sur laquelle les éléments identiques portent les mêmes références, comprend une molette 60 comprenant une partie centrale 61 plus longue que dans le mode de réalisation précédent et une crémaillère 62 aussi large que la longueur des dentures 61a de la molette 60. Toutes les autres caractéristiques du mode de réalisation précédemment décrit existent également dans ce deuxième mode de réalisation. En particulier, la partie centrale 61 de la molette 60 présente une section longitudinale suffisamment arrondie pour que le couvercle 2 puisse entourer le corps creux 5 et l'ensemble des moyens d'entraînement 51 tout en ayant une forme harmonieuse.The second embodiment illustrated in figure 9 , on which the identical elements bear the same references, comprises a wheel 60 comprising a central portion 61 longer than in the previous embodiment and a rack 62 as wide as the length of the teeth 61a of the wheel 60. All other characteristics of the embodiment previously described also exist in this second embodiment. In particular, the central portion 61 of the wheel 60 has a longitudinal section sufficiently rounded so that the cover 2 can surround the body hollow 5 and the set of drive means 51 while having a harmonious shape.

Comme illustré en figure 10, le troisième mode de réalisation comprend une molette 70 apte à coopérer avec une crémaillère convexe, la molette 10 présente un diamètre central 71 plus réduit que les diamètres latéraux 72 de sorte que la molette 70 agrippe mieux au pouce d'un opérateur. Une telle molette présente une forme générale de diabolo.As illustrated in figure 10 , the third embodiment comprises a wheel 70 adapted to cooperate with a convex rack, the wheel 10 has a central diameter 71 smaller than the lateral diameters 72 so that the wheel 70 grips better to the thumb of an operator. Such a wheel has a general form of diabolo.

Dans ce mode de réalisation, une portion ou face concave de la molette vient en prise avec une portion ou face complémentaire convexe du corps creux.In this embodiment, a portion or concave face of the wheel engages a convex complementary portion or face of the hollow body.
