Description

Domaine techniqueTechnical area

La présente invention concerne un rouge à lèvres rétractable. Par rouge à lèvres rétractable, on entend un dispositif de forme allongé permettant de sortir ou de rentrer un produit destiné à être appliqué sur les lèvres, que ce produit soit rouge ou non. Ce dispositif est également appelé bâton de rouge à lèvres ou « lipstick », selon la dénomination provenant de la langue anglaise. Plus particulièrement, la présente invention concerne un rouge à lèvres en deux parties se dévissant ou se vissant l'une par rapport à l'autre pour respectivement sortir ou rentrer le produit à lèvres d'un fourreau.The present invention relates to a retractable lipstick. By retractable lipstick is meant an elongated device for taking out or retract a product to be applied to the lips, whether the product is red or not. This device is also called lipstick stick or "lipstick", according to the denomination coming from the English language. More particularly, the present invention relates to a lipstick in two parts unscrewing or screwing relative to each other for respectively out or return the lip product of a sheath.

Etat de la techniqueState of the art

Il est connu dans l'état de la technique des rouges à lèvres dans lesquels une cupule, qui porte le produit, se visse dans une came tubulaire montée dans un fourreau de manière à rentrer le produit à lèvres dans ce fourreau. En fin de vissage, une portion de la cupule vient en appui contre le bord délimitant l'ouverture de la came tubulaire au travers de laquelle la cupule est montée dans cette came.It is known in the state of the art lipsticks in which a cup, which carries the product, is screwed into a tubular cam mounted in a sheath so as to return the lip product in this sheath. At the end of screwing, a portion of the cup abuts against the edge defining the opening of the tubular cam through which the cup is mounted in this cam.

Cet appui entraine un blocage lors du vissage, sans pour autant que l'utilisateur sache vraiment s'il est arrivé en bout de course du vissage. Cet utilisateur a alors une sensation imprécise sur le fait de savoir si le produit à lèvres est correctement rétracté, surtout dans les cas où ce produit ne se rétracte que partiellement dans le fourreau lorsque l'on ferme le rouge à lèvres.This support causes a blockage during screwing, without the user really knowing if it has reached the end of the screwing stroke. This user then has an imprecise feeling as to whether the lip product is properly retracted, especially in cases where this product only partially retracts into the sleeve when closing the lipstick.

WO2006/058668 décrit un rouge à lèvres. WO2006 / 058668 describes a lipstick.

Exposé de l'inventionPresentation of the invention

Le problème technique que vise à résoudre l'invention est donc comment indiquer clairement à l'utilisateur que le mouvement de rétractation du produit dans le fourreau du rouge à lèvres est achevé.The technical problem that the invention aims to solve is therefore how to clearly indicate to the user that the retraction movement of the product in the lipstick sheath is completed.

A cet effet, un premier objet de l'invention est un dispositif d'application de rouge à lèvres rétractable comprenant :

  • un partie de support comprenant une zone destinée à porter un produit à lèvres,
  • une partie complémentaire couplée à cette partie de support, l'une de ces dites parties comprenant une portion mâle engagée dans une portion femelle de l'autre de ces dites parties au travers d'un orifice d'entrée de la portion femelle, l'orifice d'entrée étant délimité par une bordure périphérique,
la portion mâle comprenant une forme externe coopérant avec une forme interne de la portion femelle de manière à permettre un mouvement de vissage ou un mouvement de dévissage des portions mâle et femelle entre elles, de manière à entrainer le déplacement de la partie de support par rapport à la partie complémentaire entre une position rétractée et une position déployée,
la portion mâle comprenant au moins un pion rigide et la portion femelle comprenant au moins un logement agencé sur ladite bordure périphérique et présentant un bord escamotable, la portion femelle comprenant une zone élastiquement déformable entre une forme contrainte et une forme initiale, ladite forme interne, ladite forme externe, la zone élastiquement déformable, le pion et le logement étant agencés de manière à ce que le pion et le bord escamotable viennent en interférence en fin du mouvement de vissage, le pion exerçant alors une pression directe et/ou indirecte sur la zone élastiquement déformable, qui se déforme alors vers sa forme contrainte de manière à décaler le bord escamotable par rapport au pion, de manière à laisser le pion se loger dans le logement, de sorte que la zone élastiquement déformable revient alors vers sa forme initiale, le bord escamotable revenant en arrière du pion selon le sens du vissage, la partie support étant alors dans sa position rétractée.For this purpose, a first object of the invention is a retractable lipstick application device comprising:
  • a support part comprising a zone intended to carry a lip product,
  • a complementary portion coupled to this support portion, one of said portions comprising a male portion engaged in a female portion of the other of said parts through an inlet of the female portion, the inlet orifice being delimited by a peripheral edge,
the male portion comprising an outer shape cooperating with an internal shape of the female portion so as to allow a screwing movement or a unscrewing movement of the male and female portions together, so as to cause the displacement of the support portion relative to at the complementary part between a retracted position and an extended position,
the male portion comprising at least one rigid pin and the female portion comprising at least one housing arranged on said peripheral edge and having a retractable edge, the female portion comprising an elastically deformable zone between a constrained shape and an initial shape, said internal shape, said outer shape, the elastically deformable zone, the pin and the housing being arranged in such a way that the pin and the retractable edge come into interference at the end of the screwing movement, the pin then exerting a direct and / or indirect pressure on the an elastically deformable zone, which then deforms towards its constrained shape so as to shift the retractable edge relative to the pin, so as to allow the pin to be housed in the housing, so that the elastically deformable zone then returns to its initial shape, the retractable edge returning behind the pin in the direction of screwing, the support part then being in its retracted position.

Ainsi, en fin de course du mouvement de rétractation du produit à lèvres, lorsque celui-ci est fixé à la zone destinée à le recevoir, un clipage réversible s'opère entre le pion et le logement. Ce clipage crée une indication à l'utilisateur que le mouvement de rétractation est terminé et qu'il n'est plus nécessaire de visser.Thus, at the end of the stroke of the retraction movement of the lip product, when it is fixed to the zone intended to receive it, a reversible clipping takes place between the pawn and the dwelling. This clipping creates an indication to the user that the retraction movement is complete and that it is no longer necessary to screw.

Le pion est dit rigide par comparaison à la zone élastiquement déformable. Ainsi la compression du pion et du bord escamotable l'un contre l'autre entraine essentiellement la déformation de cette zone élastiquement déformable. Le dispositif d'application selon l'invention peut optionnellement présenter une ou plusieurs des caractéristiques suivantes :

  • le bord escamotable comprend la zone élastiquement déformable, le bord escamotable étant ainsi agencé de manière à être élastiquement déformable entre une forme initiale et une forme escamotée ; ainsi le bord escamotable s'escamote en se déformant et laisse passer le pion dans le logement, le bord revenant ensuite en arrière de ce pion ; c'est une forme simple à réaliser ;
  • la portion femelle peut comprendre une paroi enveloppante formant une enveloppe entourant la portion mâle et présentant une tranche formant ladite bordure périphérique, le ou les logements étant formés dans cette paroi enveloppante, la paroi enveloppante comprenant un évidement agencé dans le bord escamotable à distance de la tranche de ce bord venant en interférence avec le pion en fin de vissage ; la réalisation du bord escamotable est ainsi simplifiée, l'évidement créant une zone moins épaisse, formant une zone de faiblesse facilitant la déformation de la paroi, puis son retour à sa forme initiale lorsque la contrainte de déformation cesse ;
  • le bord escamotable est un doigt escamotable délimité par l'évidement, l'évidement étant une échancrure courbée débouchant sur la tranche formant ladite bordure périphérique et passant sous le doigt escamotable ; ainsi le bord escamotable est réalisé par simple découpe de la paroi de la portion femelle ;
  • la zone élastiquement déformable peut être agencée à distance du bord escamotable mais agencée de manière à permettre un déplacement desdites formes interne et externe, de manière à déplacer la partie femelle selon un sens et une direction inverse à la direction de vissage, entrainant ainsi le retrait du bord escamotable par rapport au pion ; on entend par direction de vissage, la direction parallèle à l'axe autour duquel se réalise le vissage ; une fois le pion en vis-à-vis du logement, l'élasticité de la zone élastiquement déformable rappelle le pion dans le logement ; il n'est ainsi pas nécessaire de réaliser un bord escamotable déformable ; on peut cependant combiner les deux ;
  • la zone élastiquement déformable comprend ladite forme interne de la portion femelle, cette forme interne, la forme externe de la portion mâle et la zone déformable étant agencées de manière à ce que la pression du pion sur le bord escamotable soit transférée par la portion femelle à ladite forme interne qui est pressée contre ladite forme externe, entrainant ainsi à la fois le décalage de ladite forme interne par rapport à cette forme externe tout en restant en contact avec celle-ci, et à la fois la déformation de la zone déformable, de manière à déplacer la portion femelle et donc le bord escamotable en retrait par rapport au pion, permettant ainsi la poursuite du vissage et la génération d'une force de rappel du logement en sens opposé audit retrait, de sorte que le pion puisse se placer en vis-à-vis du logement, puis que la zone déformable rappelle ladite forme interne vers une position sans contrainte, le logement venant alors entourer le pion, la partie support étant alors dans sa position rétractée ;
  • la portion mâle présente au moins un filet agencé à l'extérieur de cette portion mâle, ladite forme interne de la portion femelle comprenant un relief de vissage agencé de manière à coulisser dans le filet, la zone déformable comprenant le relief de vissage, le filet et la zone déformable sont agencés de manière à ce que la pression du pion sur le bord escamotable entraine la compression du relief de vissage contre un flanc du filetage orienté en direction du pion, entrainant ainsi à la fois l'écartement selon une composante radiale du relief de vissage, le glissement de ce relief de vissage sur ce flanc du fond du filet vers le sommet du filet, et la déformation de la zone élastiquement déformable, de sorte que la portion femelle et le bord escamotable se déplacent en retrait par rapport au pion, permettant ainsi la poursuite du vissage et la génération d'une force de rappel du logement en sens opposé audit retrait, de sorte que le pion puisse se placer en vis-à-vis du logement, puis que la zone déformable rappelle le relief de vissage le long dudit flanc et vers le fond du filet, le logement venant alors entourer le pion, la partie support étant alors dans sa position rétractée ; ainsi la zone déformable crée un jeu entre le filet et le relief de vissage permettant le déplacement de la portion femelle dans une direction opposée à la direction de vissage et le rappel selon cette direction de vissage ;
  • le relief de vissage est une saillie courbée, par exemple en forme de croissant de lune ;
  • la portion mâle s'étend selon sa longueur entre une première et une deuxième extrémités qui sont respectivement à l'extérieur et à l'intérieur de la portion femelle en position déployée, la profondeur du logement selon une direction longitudinale étant inférieure à la hauteur selon une direction longitudinale entre le fond du filet et le sommet du filet reliés par le flanc au-dessus et en vis-à-vis du pion ; cela permet de renforcer le rappel du logement vers le pion ;
  • le bord escamotable présente selon le sens du vissage un bord arrière et un bord avant, dit bord d'attaque, et présente également une inclinaison telle que la distance entre le bord d'attaque et la première extrémité de la portion mâle soit plus grande que la distance entre le bord arrière et la première extrémité de la portion mâle ; cela facilite par réaction le déplacement en retrait du bord escamotable par rapport au pion ;
  • le logement est délimité d'un côté par le bord escamotable et de l'autre par un bord, dit bord de butée, la profondeur du logement selon une direction longitudinale étant inférieure du côté du bord escamotable à celle du côté du bord de butée; cela facilite la sortie du pion du logement lorsque l'utilisateur actionne le dispositif d'application vers la position déployée ;
  • la portion mâle s'étend selon sa longueur entre une première et une deuxième extrémités qui sont respectivement à l'extérieur et à l'intérieur de la portion femelle en position déployée ; cette première extrémité peut être adjacente à une collerette, la collerette étant plus large que la portion mâle et comportant le ou les pions rigides du côté de la portion mâle ; cette collerette forme ainsi une butée de vissage, d'une façon simple à réaliser ;
  • la tranche formant la bordure périphérique peut être agencée en vis-à-vis de la collerette, le ou les logements débouchant en vis-à-vis de la collerette ; cela permet une approche progressive du logement et du pion ; par ailleurs, cela permet une réalisation simple du pion et du logement correspondant pour un clipage en fin de vissage ;
  • la portion femelle comprend une paroi enveloppante formant une enveloppe entourant la portion mâle et présentant une tranche formant ladite bordure périphérique, le ou les logements étant formés dans cette paroi enveloppante, la paroi enveloppante comprenant au moins une fente débouchant au niveau de la tranche formant la bordure périphérique ;
  • la ou les fentes peuvent être agencées de manière à permettre par une déformation élastique un écartement et un rapprochement des portions de la paroi enveloppante qui sont séparées par cette ou ces fentes, de manière à permettre l'enfoncement de la portion mâle dans la portion femelle selon un mouvement de translation simple ; par translation simple on entend un mouvement selon uniquement une direction et un sens sans rotation ; cela permet de monter aisément et rapidement la portion mâle dans la portion femelle à fond, sans avoir à visser ces portions entre elles ; on simplifie ainsi le montage du dispositif d'application ;
  • le ou chacun desdits logements est formé à distance de ces fentes ;
  • le dispositif d'application peut comprendre deux dites fentes, celles-ci étant diamétralement opposées ; cela permet un écartement plus facile ;
  • la ou lesdites fentes peuvent s'étendre selon la direction de la longueur de la portion femelle ; cela permet un écartement plus facile ;
  • le dispositif d'application peut comprendre un fourreau dans lequel sont montées la partie de support et la partie complémentaire, la partie complémentaire étant fixée au fourreau de manière à être, par rapport à ce dernier, mobile en rotation et fixe en translation, de sorte que la rotation de la partie complémentaire permette le coulissement hélicoïdal de la partie support le long du fourreau, le fourreau présentant une ouverture en vis-à-vis de la portion de la zone destinée à porter un produit à lèvres ; cela permet de protéger les deux parties en formant une gaine de protection extérieur du dispositif d'application ; par ailleurs, la partie complémentaire forme ainsi une came dont la rotation se transforme par coopération de ses formes avec celles de la partie de support en un mouvement de translation de cette dernière ;
  • la portion mâle présente une rainure hélicoïdale s'étendant autour et le long d'un axe longitudinal de cette portion mâle, notamment une rainure formée par un filetage agencé à l'extérieur de cette portion mâle ; la portion femelle peut présenter un relief de vissage, notamment une saillie courbée, par exemple en forme de croissant de lune, agencée de manière à coulisser dans la rainure ; ce sont des manières simple de réaliser une forme externe coopérant avec une forme interne de la portion femelle de manière à permettre un mouvement de vissage ou un mouvement de dévissage des portions mâle et femelle entre elles ;
  • la portion mâle présente un double filet et la portion femelle comprend deux reliefs de vissage, un premier relief de vissage coopérant avec un premier filet et un deuxième relief de vissage coopérant avec un deuxième filet ; le guidage est ainsi amélioré ;

  • le dispositif d'application peut comprendre un produit à lèvres fixé à la zone destinée à le recevoir ; c'est le cas, lorsque le dispositif d'application est prêt à être utilisé ; ce produit à lèvres peut par exemple être un fard, rouge ou non, ou encore un produit de soin ou de protection, par exemple contre les gerçures.
The pin is said to be rigid compared to the elastically deformable zone. Thus the compression of the pin and the retractable edge against each other essentially causes the deformation of this elastically deformable zone. The application device according to the invention may optionally have one or more of the following characteristics:
  • the retractable edge comprises the elastically deformable zone, the retractable edge thus being arranged to be elastically deformable between an initial shape and a retracted shape; thus the retractable edge retracts by deforming itself and lets the piece pass through the housing, the edge then returning behind this piece; it is a simple form to realize;
  • the female portion may comprise an enveloping wall forming an envelope surrounding the male portion and having a slice forming said peripheral edge, the housing or housing being formed in this enveloping wall, the enveloping wall comprising a recess arranged in the retractable edge at a distance from the wafer of this edge coming into interference with the pawn at the end of screwing; the realization of the retractable edge is thus simplified, the recess creating a less thick zone, forming a zone of weakness facilitating the deformation of the wall, then its return to its original shape when the strain of strain ceases;
  • the retractable edge is a retractable finger delimited by the recess, the recess being a curved indentation opening on the edge forming said peripheral edge and passing under the retractable finger; thus the retractable edge is made by simply cutting the wall of the female portion;
  • the elastically deformable zone may be arranged at a distance from the retractable edge but arranged so as to allow displacement of said inner and outer shapes, so as to move the female part in a direction and a direction opposite to the screwing direction, thus causing the withdrawal the retractable edge relative to the pawn; the term "screwing direction" is understood to mean the direction parallel to the axis around which screwing takes place; once the pawn vis-à-vis the housing, the elasticity of the elastically deformable area recalls the pawn in the housing; it is thus not necessary to make a deformable retractable edge; we can, however, combine the two;
  • the elastically deformable zone comprises said internal shape of the female portion, this internal shape, the external shape of the male portion and the deformable zone being arranged in such a way that the pressure of the pin on the retractable edge is transferred by the female portion to said internal shape which is pressed against said external shape, thus causing both the offset of said inner shape with respect to this external shape while remaining in contact therewith, and both the deformation of the deformable zone, so as to move the female portion and thus the retractable edge recessed relative to the pin, thus allowing the continuation of the screwing and the generation of a return force of the housing in the opposite direction to said withdrawal, so that the pin can be placed in vis-à-vis the housing, and that the deformable area recalls said internal shape to a position without constraint, housing then surrounding the pawn, the part support being then in its retracted position;
  • the male portion has at least one thread arranged outside this male portion, said internal shape of the female portion comprising a screw-in relief arranged so as to slide in the thread, the deformable zone comprising the screw-in relief, the thread and the deformable zone are arranged in such a way that the pressure of the peg on the retractable edge causes the compression of the screwing relief against a flank of the thread facing in the direction of the pin, thus causing both the spacing along a radial component of the screwing relief, the sliding of this screwing relief on this flank of the bottom of the thread towards the top of the thread, and the deformation of the elastically deformable zone, so that the female portion and the retractable edge move back from the pin, thus allowing the continuation of the screwing and the generation of a return force of the housing in the opposite direction to said withdrawal, so that the pin can be placed in with respect to the housing, then that the deformable area recalls the screwing relief along said sidewall and towards the bottom of the net, the housing then surrounding the pin, the support portion then being in its retracted position; and the deformable zone creates a clearance between the thread and the screwing relief allowing the displacement of the female portion in a direction opposite to the screwing direction and the return in this direction of screwing;
  • the screw-in relief is a curved protrusion, for example in the shape of a crescent moon;
  • the male portion extends along its length between a first and a second end which are respectively outside and inside the female portion in the deployed position, the depth of the housing in a longitudinal direction being less than the height according to a longitudinal direction between the bottom of the net and the top of the net connected by the side above and opposite the pin; this reinforces the reminder of housing towards the pawn;
  • the retractable edge has in the direction of screwing a rear edge and a front edge, said leading edge, and also has an inclination such that the distance between the leading edge and the first end of the male portion is larger than the distance between the rear edge and the first end of the male portion; this facilitates by reaction the displacement back of the retractable edge relative to the pin;
  • the housing is delimited on one side by the retractable edge and the other by an edge, said abutment edge, the depth of the housing in a longitudinal direction being lower on the side of the retractable edge to that of the side of the abutment edge; this facilitates the exit of the housing pin when the user actuates the application device to the deployed position;
  • the male portion extends along its length between a first and a second end which are respectively outside and inside the female portion in the deployed position; this first end may be adjacent to a collar, the collar being wider than the male portion and having the rigid pin or pins on the side of the male portion; this collar thus forms a screw abutment, in a simple way to achieve;
  • the edge forming the peripheral edge can be arranged vis-à-vis the flange, the housing or openings opening vis-à-vis the flange; this allows a progressive approach to housing and pawn; moreover, this allows a simple realization of the pin and the corresponding housing for clipping at the end of screwing;
  • the female portion comprises an enveloping wall forming an envelope surrounding the male portion and having a slice forming said edge peripheral, the housing or housing being formed in this enveloping wall, the enveloping wall comprising at least one slot opening at the edge forming the peripheral edge;
  • the slot or slots may be arranged so as to allow by elastic deformation spacing and approximation of the portions of the enveloping wall which are separated by this or these slots, so as to allow the depression of the male portion in the female portion according to a simple translational movement; by simple translation we mean a movement according to only one direction and one direction without rotation; this allows to easily and quickly mount the male portion in the female portion thoroughly, without having to screw these portions together; this simplifies the mounting of the application device;
  • the or each said housing is formed at a distance from these slots;
  • the application device may comprise two said slots, these being diametrically opposed; this allows for easier spacing;
  • the at least one slot may extend in the direction of the length of the female portion; this allows for easier spacing;
  • the applicator device may comprise a sleeve in which the support part and the complementary part are mounted, the complementary part being fixed to the sheath so as to be movable in rotation relative to the latter and fixed in translation, so that that the rotation of the complementary part allows the helical sliding of the support part along the sleeve, the sleeve having an opening vis-à-vis the portion of the zone intended to carry a lip product; this makes it possible to protect the two parts by forming an outer protective sheath of the application device; moreover, the complementary part thus forms a cam whose rotation is transformed by cooperation of its forms with those of the support part in a translational movement of the latter;
  • the male portion has a helical groove extending around and along a longitudinal axis of this male portion, in particular a groove formed by a thread arranged outside of this male portion; the female portion may have a screw-in relief, in particular a curved projection, for example in the shape of a crescent moon, arranged so as to slide in the groove; these are simple ways of achieving an external form cooperating with an internal form of the female portion so as to allow a screwing movement or a unscrewing movement of the male and female portions together;
  • the male portion has a double thread and the female portion comprises two screwing reliefs, a first screwing relief cooperating with a first thread and a second screwing relief cooperating with a second thread; the guidance is thus improved;

  • the support portion comprises the female portion and the complementary portion comprises the male portion;
  • the supporting portion and / or the complementary portion may be of polymer (s); this makes it possible to produce the parts by injection or by molding;

  • the application device may comprise a lip product attached to the zone intended to receive it; this is the case when the application device is ready to be used; this lip product may for example be a blush, red or not, or a care product or protection, for example against cracks.

Un autre objet de l'invention est une partie femelle de dispositif d'application de rouge à lèvres rétractable comprenant une portion femelle dans laquelle est destinée à être insérée une portion mâle d'une partie mâle du dispositif d'application de manière à permettre un mouvement de vissage et un mouvement de dévissage des portions mâle et femelle entre elles par coopération d'une forme interne de la portion femelle avec une forme externe de la portion mâle, de manière à entrainer le déplacement de ces deux parties entre une position rétractée et une position déployée. Selon cet objet, la portion femelle comprend une paroi enveloppante formant une enveloppe destinée à entourer la portion mâle, cette paroi enveloppante présentant une tranche formant une bordure périphérique délimitant un orifice d'entrée pour l'insertion de la portion mâle ;
la portion femelle comprend au moins un logement, ce logement étant:

  • avec un bord, dit bord escamotable ;
et en ce que la paroi enveloppante comprend un évidement agencé dans le bord escamotable et à distance de la tranche 77a de ce bord escamotable à l'extrémité de cette portion femelle.Another object of the invention is a retractable lipstick applicator female part comprising a female portion in which is intended to be inserted a male portion of a male portion of the applicator device so as to allow a screwing movement and a unscrewing movement of the male and female portions together by cooperation of an internal shape of the female portion with an external shape of the male portion, so as to cause the movement of these two parts between a retracted position and an unfolded position. According to this object, the female portion comprises an enveloping wall forming an envelope intended to surround the male portion, this enveloping wall having a wafer forming a peripheral edge defining an inlet for the insertion of the male portion;

Description détailléedetailed description

La figure 1 illustre une vue éclatée des différentes pièces formant un exemple de dispositif d'application 1 d'un produit à lèvres selon un exemple de réalisation de l'invention.The figure 1 illustrates an exploded view of the various parts forming an example of application device 1 of a lip product according to an exemplary embodiment of the invention.

Dans cet exemple, le dispositif d'application a la forme d'un stylo.In this example, the application device is in the form of a pen.

Sur cette figure 1, le produit à lèvres n'est pas représenté. Par exemple, l'ensemble du dispositif d'application 1 peut être fabriqué et livré séparément du produit à lèvres, avant positionnement de ce dernier dans ce dispositif 1.On this figure 1 the lip product is not shown. For example, the entire application device 1 can be manufactured and delivered separately from the lip product, before positioning the latter in this device 1.

Le dispositif d'application comprend un fourreau 3, ici formé par une unique pièce, dans lequel sont montés une première partie de support 4 et une partie complémentaire 5 de cette dernière.The application device comprises a sleeve 3, here formed by a single piece, in which are mounted a first support portion 4 and a complementary portion 5 thereof.

La partie de support 4 comprend une zone destinée à recevoir le produit à lèvres, ci-après appelée zone de réception 42. Cette dernière étant agencée à l'une des extrémités de la partie support à 4.The support portion 4 comprises a zone intended to receive the lip product, hereinafter called the receiving zone 42. The latter being arranged at one of the ends of the support part at 4.

Dans cet exemple, la partie support 4 comprend d'un côté, ici en haut, un réceptacle 41 comprenant une zone 42 destinée à recevoir le produit à lèvres. Ce produit à lèvres est généralement appelé raisin et se positionne dans le réceptacle 41. C'est donc cette partie de support 4 qui supporte le raisin, elle est généralement appelée, comme ci-après, cupule.In this example, the support portion 4 comprises on one side, here above, a receptacle 41 comprising a zone 42 for receiving the lip product. This lip product is generally called grape and is positioned in the receptacle 41. It is therefore this support portion 4 which supports the grape, it is generally called, as below, cupule.

Cette cupule 4 comprend de l'autre côté, ici en bas, une portion qui forme une portion femelle 40 alignée avec la zone de réception 42 et qui est globalement de forme tubulaire.This cup 4 comprises on the other side, here below, a portion which forms a female portion 40 aligned with the receiving zone 42 and which is generally tubular in shape.

La partie complémentaire 5, comprend d'un côté une portion mâle 50, s'emboîtant dans la portion femelle 40, comme il sera expliqué ci-après.The complementary part 5 comprises on one side a male portion 50, fitting into the female portion 40, as will be explained below.

Une fois emboîtées, cette portion mâle 50 et cette portion femelle 40 peuvent se visser et se dévisser entre elles. En d'autres termes, la partie de support 4 et la partie complémentaire 5 forment donc respectivement une partie femelle et une partie mâle coopérant entre elle par vissage ou dévissage.Once nested, this male portion 50 and this female portion 40 can screw and unscrew them. In other words, the support part 4 and the complementary part 5 thus form respectively a female part and a male part cooperating with it by screwing or unscrewing.

Cette partie complémentaire 5 comprend une portion d'actionnement 58, alignée avec la portion mâle 50. Autrement dit la portion d'actionnement est alignée avec l'axe longitudinal A, représenté en figure 2 et selon lequel le dispositif d'application 1 s'étend selon sa longueur, de bas en haut.This complementary part 5 comprises an actuating portion 58, aligned with the male portion 50. In other words, the actuating portion is aligned with the longitudinal axis A, shown in FIG. figure 2 and wherein the application device 1 extends along its length from bottom to top.

Un joint 6 est monté autour de la partie complémentaire 5 entre la portion mâle 50 et la portion d'actionnement 58.A seal 6 is mounted around the complementary portion 5 between the male portion 50 and the actuating portion 58.

Le dévissage et le vissage entre les portions mâle 50 et femelle 40 permettent d'actionner respectivement la sortie du fourreau 3 et la rétractation dans le fourreau 3 du produit à lèvres au travers d'une ouverture 31 de ce fourreau 3, cette ouverture 31 étant agencée en vis-à-vis de la zone de réception 42.The unscrewing and the screwing between the male 50 and female 40 portions respectively enable the outlet of the sleeve 3 and the retraction in the sheath 3 of the lip product to pass through an opening 31 of this sheath 3, this opening 31 being arranged opposite the reception zone 42.

Pour cela, la portion mâle 50 est pourvue d'une forme externe coopérant avec une forme interne de la portion femelle 40, ces formes étant agencées de manière à permettre le vissage et le dévissage de la cupule 4 et de sa partie complémentaire 5.For this, the male portion 50 is provided with an external shape cooperating with an internal shape of the female portion 40, these shapes being arranged to allow the screwing and unscrewing of the cup 4 and its complementary part 5.

Comment on peut le voir en figures 2 à 4, la partie complémentaire 5 est montée bloquée en translation dans le fourreau 3 et est libre en rotation dans celui-ci. Ainsi, l'actionnement en rotation de la portion mâle 50, entraine, selon le sens de rotation, le vissage ou le dévissage de la cupule 4 dans la partie complémentaire 5, ce qui entraine le coulissement de la cupule 4 dans le fourreau 3 entre une position rétractée, illustrée en figure 2, et une position déployée, illustrée en figure 3. Le dévissage permet donc de passer de la position rétractée à la position déployée, et le vissage permet de passer de la position déployée à la position rétractée.How can we see it in Figures 2 to 4 , the complementary part 5 is mounted locked in translation in the sheath 3 and is free to rotate therein. Thus, the actuation in rotation of the male portion 50, causes, in the direction of rotation, the screwing or unscrewing of the cup 4 in the complementary part 5, which causes the sliding of the cup 4 in the sheath 3 between a retracted position, illustrated in figure 2 , and a deployed position, illustrated in figure 3 . The unscrewing thus makes it possible to pass from the retracted position to the deployed position, and the screwing makes it possible to move from the deployed position to the retracted position.

La partie complémentaire forme donc ici une came 5.The complementary part thus forms a cam 5 here.

La portion d'actionnement 58 permet par rotation d'entraîner la rotation de la came 5.The actuating portion 58 rotates to cause the cam 5 to rotate.

Le dispositif d'application 1, peut comprendre comme ici un capuchon 2, permettant de fermer l'ouverture 31.The application device 1, can comprise as here a cap 2, for closing the opening 31.

Dans cet exemple, la portion d'actionnement 58 est recouverte par un carénage 7, ci-après appelé base 7. Cette dernière peut, comme ici, avoir la forme d'une cuve dont le fond est agencé en bas sur la figure 1. La portion d'actionnement 58 peut ainsi être emmanchée dans cette base 7.In this example, the actuating portion 58 is covered by a shroud 7, hereinafter called base 7. The latter can, as here, be in the form of a tank whose bottom is arranged on the bottom. figure 1 . The actuating portion 58 can thus be fitted into this base 7.

Cette base 7 outre qu'elle protège la came 5, permet d'assurer une continuité esthétique avec le fourreau 3. Par exemple, cette base 7 peut avoir le même diamètre externe que le fourreau 3.This base 7, in addition to protecting the cam 5, makes it possible to ensure an aesthetic continuity with the sheath 3. For example, this base 7 may have the same external diameter as the sheath 3.

Dans la présente demande, les termes « haut » et « bas » sont appliqués selon l'orientation des différents éléments tels qu'ils sont illustrés dans les figures de la demande. Cette orientation correspond à l'orientation du dispositif d'application 1 ou à l'orientation de ses éléments dans le dispositif d'application 1, lorsque l'on pose ce dernier verticalement, par exemple sur une table en appui sur le fond de sa base 7, la zone de réception 42 étant alors orientée vers le haut.In the present application, the terms "high" and "low" are applied according to the orientation of the various elements as they are illustrated in the figures of the application. This orientation corresponds to the orientation of the application device 1 or the orientation of its elements in the application device 1, when the latter is placed vertically, for example on a table resting on the bottom of its base 7, the receiving zone 42 then being oriented upwards.

La cupule 4 et la came 5 vont maintenant être détaillées en référence aux figures 5 à 11.The cup 4 and the cam 5 will now be detailed with reference to Figures 5 to 11 .

La cupule 4 est illustrée en figure 5, 6 et 11.The cup 4 is illustrated in Figure 5, 6 and 11 .

Celle-ci s'étend en longueur selon un axe longitudinal qui correspond à l'axe longitudinal A du dispositif d'application 1.It extends in length along a longitudinal axis which corresponds to the longitudinal axis A of the application device 1.

La zone de réception est formée, dans cet exemple, par des lamelles 42.The receiving zone is formed in this example by lamellae 42.

Elle se situe ici au-dessus de la portion femelle 40.It is located here above the female portion 40.

Le raisin peut être monté par emmanchement du raisin dans le réceptacle 41. Dans cet exemple, lors du montage du raisin, les lamelles 42 viennent pénétrer à l'intérieur du bas du raisin de manière à améliorer sa fixation dans le réceptacle 41.The grape can be mounted by fitting the grapes into the receptacle 41. In this example, during the assembly of the grapes, the slats 42 penetrate inside the bottom of the grapes so as to improve its fixation in the receptacle 41.

La portion femelle 40 est formée par une paroi tubulaire, ci-après paroi enveloppante 48. Cette portion femelle 50 peut comprendre à l'extérieur de sa paroi enveloppante 48, des moyens de guidage 45a, 45b, agencés de manière à glisser le long des parois interne du fourreau 3.The female portion 40 is formed by a tubular wall, hereinafter an enveloping wall 48. This female portion 50 may comprise, outside its enveloping wall 48, guide means 45a, 45b, arranged so as to slide along the inner wall of the sheath 3.

Les moyens de guidage 45a, 45b peuvent eux être des portions de cylindre dont les directrices sont parallèles à l'axe longitudinal A.The guide means 45a, 45b can be cylinder portions whose directions are parallel to the longitudinal axis A.

Cette portion femelle 40 présente en bas un orifice d'entrée 49 par lequel est insérée la portion mâle 50 lors du montage du dispositif d'application 1.This female portion 40 has at the bottom an inlet orifice 49 through which is inserted the male portion 50 during assembly of the application device 1.

Cet orifice d'entrée 49 est délimitée par une tranche de la paroi enveloppante 48, cette tranche formant la bordure périphérique 46 de la portion femelle 40.This inlet orifice 49 is delimited by a slice of the enveloping wall 48, this slice forming the peripheral edge 46 of the female portion 40.

Dans cet exemple, la paroi enveloppante 48 de la portion femelle 40 comprend deux logements 64a, 64b formés ici par une encoche.In this example, the enveloping wall 48 of the female portion 40 comprises two housings 64a, 64b formed here by a notch.

Selon l'invention, comme ici, les logements 64a, 64b peuvent être agencés sensiblement perpendiculairement au plan passant par cette tranche 46.According to the invention, as here, the housings 64a, 64b can be arranged substantially perpendicular to the plane passing through this wafer 46.

Chacun de ces logements 64a, 64b est formé au travers de la paroi enveloppante 48 et débouche sur cette tranche 46.Each of these housings 64a, 64b is formed through the enveloping wall 48 and opens on this wafer 46.

Au niveau de chacun des logements 64a, 64b, l'un des coins formés entre la tranche 46 formant la bordure périphérique et le logement 64a, 64b correspondant, est formé par un doigt 60a, 60b.At each of the housings 64a, 64b, one of the corners formed between the edge 46 forming the peripheral edge and the corresponding housing 64a, 64b, is formed by a finger 60a, 60b.

Comme on peut le voir en figure 5 et 6, et de manière plus détaillée en figure 11, la paroi enveloppante 48 présente une échancrure 63a, 63b courbée.As we can see in figure 5 and 6 , and in more detail in figure 11 , the enveloping wall 48 has a notch 63a, 63b curved.

L'échancrure 63a, 63b est ici en forme de « L », dont les branches du « L » sont formées par une portion longitudinale 74a et une portion transversale 73a. La portion longitudinale 74a débouche sur la tranche 46 formée par la bordure périphérique. La portion transversale 73a passe au-dessus du doigt 60a, 60b, délimitant ainsi le doigt 60a, 60b vers le haut. En bas, le doigt 60a, 60b forme une portion de la tranche périphérique.The notch 63a, 63b is here in the form of "L", whose branches of the "L" are formed by a longitudinal portion 74a and a transverse portion 73a. The longitudinal portion 74a opens on the edge 46 formed by the peripheral edge. The transverse portion 73a passes above the finger 60a, 60b, thus defining the finger 60a, 60b upwards. At the bottom, the finger 60a, 60b forms a portion of the peripheral edge.

L'échancrure 63a, 63b délimite ainsi une extrémité libre du doigt 60a, 60b. Cette extrémité libre forme le bord avant 61a dans le sens du vissage.The notch 63a, 63b thus delimits a free end of the finger 60a, 60b. This free end forms the front edge 61a in the screwing direction.

La portion longitudinale 74a forme un évidement au-dessus du doigt 60a, 60b, permettant ainsi une déformation élastique optimale du doigt, qui forme donc un doigt escamotable 60a, 60b. Le doigt 60a, 60b peut ainsi plier vers le haut, à l'intérieur de l'échancrure 63a, 63b.The longitudinal portion 74a forms a recess above the finger 60a, 60b, thus allowing optimal elastic deformation of the finger, which thus forms a retractable finger 60a, 60b. The finger 60a, 60b can thus bend upwards, inside the notch 63a, 63b.

Le doigt escamotable 60a, 60b sépare la portion longitudinale 74a de l'échancrure 63a, 63b et forme donc un bord escamotable du logement 64a, 64b.The retractable finger 60a, 60b separates the longitudinal portion 74a of the notch 63a, 63b and therefore forms a retractable edge of the housing 64a, 64b.

Par ailleurs, le bord arrière 62a du doigt escamotable 60a, 60b forme donc également un bord avant du logement 64a, 64b.Moreover, the rear edge 62a of the retractable finger 60a, 60b also forms a front edge of the housing 64a, 64b.

Au-dessus de la tranche formant la bordure périphérique 46 et à l'intérieur de la paroi enveloppante 48, est agencée une forme interne 47a, 47b en forme de croissant de lune. Celle-ci peut présenter une légère inclinaison par rapport à l'axe longitudinal A de la cupule 4, donc de la portion femelle 40, de manière à coopérer avec des rainures 57a, 57b de la portion mâle 50, comme cela sera expliqué plus loin.Above the edge forming the peripheral rim 46 and inside the wrapping wall 48 is arranged an inner shape 47a, 47b crescent-shaped. This may have a slight inclination with respect to the longitudinal axis A of the cup 4, therefore of the female portion 40, so as to cooperate with grooves 57a, 57b of the male portion 50, as will be explained later .

Dans cet exemple, la paroi enveloppante 48 de la portion femelle 40 comprend deux fentes 43a, 43b s'étendant longitudinalement, à savoir sensiblement parallèlement à l'axe longitudinal A de la cupule 4.In this example, the enveloping wall 48 of the female portion 40 comprises two slots 43a, 43b extending longitudinally, namely substantially parallel to the longitudinal axis A of the cup 4.

Selon l'invention, comme ici, les fentes 43a, 43b peuvent être agencées sensiblement perpendiculairement au plan passant par cette tranche 46.According to the invention, as here, the slots 43a, 43b can be arranged substantially perpendicular to the plane passing through this wafer 46.

Chacune de ces fentes 43a, 43b est formée au travers de la paroi enveloppante 48 de la portion femelle 40 et débouche sur cette tranche 46.Each of these slots 43a, 43b is formed through the enveloping wall 48 of the female portion 40 and opens on this wafer 46.

Dans cet exemple, les fentes 43a, 43b sont diamétralement opposées et séparent la paroi enveloppante 48, en bas de celle-ci, en deux portions flexibles 44a, 44b susceptibles de s'écarter l'une de l'autre, selon une direction transversale à l'axe longitudinal A. Autrement dit, ces portions flexibles 44a, 44b sont susceptibles de s'écarter sur les côtés de la cupule 4.In this example, the slots 43a, 43b are diametrically opposed and separate the enveloping wall 48, at the bottom thereof, into two flexible portions 44a, 44b which can move apart from each other in a transverse direction. to the longitudinal axis A. In other words, these flexible portions 44a, 44b are likely to deviate on the sides of the cup 4.

En figures 7 et 8 est représentée la came 5.In Figures 7 and 8 is represented the cam 5.

Celle-ci s'étend en longueur selon un axe longitudinal, qui correspond à l'axe longitudinal A du dispositif d'application 1.It extends in length along a longitudinal axis, which corresponds to the longitudinal axis A of the application device 1.

Comme on peut le voir sur celles-ci, la portion mâle 50 et la portion d'actionnement 58 sont séparées l'une de l'autre par une collerette 53, une gorge 67 annulaire, une première nervure externe annulaire 66, ainsi qu'un deuxième nervure externe annulaire 68.As can be seen on them, the male portion 50 and the actuating portion 58 are separated from each other by a collar 53, an annular groove 67, a first annular outer rib 66, and a second annular external rib 68.

La portion mâle 50, la collerette 53, la gorge 67, la première nervure externe annulaire 66, la deuxième nervure externe annulaire 68 et la portion d'actionnement 58 sont agencés de haut en bas le long de l'axe longitudinal A de la came 5 et répartis chacun autour de cet axe.The male portion 50, the flange 53, the groove 67, the first annular outer rib 66, the second annular outer rib 68 and the actuating portion 58 are arranged up and down along the longitudinal axis A of the cam 5 and distributed each around this axis.

La gorge 67 reçoit un joint 6, comme notamment illustré en figure 9a (ce joint n'étant pas représenté en figures 7 et 8).The groove 67 receives a seal 6, as illustrated in particular in figure 9a (this seal is not represented in Figures 7 and 8 ).

Lorsque cette came 5 est montée dans le fourreau 3, tel qu'illustré en figure 4, une première nervure annulaire interne 32, ménagée sur la paroi interne du fourreau 3 et à l'extrémité basse de ce dernier, est agencée entre la collerette 53 et la première nervure annulaire externe 66.When this cam 5 is mounted in the sheath 3, as illustrated in FIG. figure 4 a first internal annular rib 32 formed on the inner wall of the sleeve 3 and at the lower end thereof is arranged between the collar 53 and the first outer annular rib 66.

Lorsque la came 5 est montée dans le fourreau 3, la gorge 67 est agencée juste en vis-à-vis de la première nervure annulaire interne 32, ce qui fait que le joint 6 est comprimé contre le fourreau 3 en dessous de la collerette 53. La came 5 est dépourvue de passage menant à l'intérieur du fourreau. De ce fait, cela permet de réaliser l'étanchéité entre l'extérieur et l'intérieur du dispositif d'application 1, et en particulier entre le fourreau 3 et la came 5 en bas du fourreau 3. On évite ainsi l'entrée de poussière ou d'humidité entre le fourreau 3 et cette came 5.When the cam 5 is mounted in the sleeve 3, the groove 67 is arranged just opposite the first internal annular rib 32, so that the seal 6 is pressed against the sleeve 3 below the collar 53 The cam 5 is devoid of passage leading to the inside of the sheath. Therefore, this makes it possible to seal between the outside and the inside of the application device 1, and in particular between the sheath 3 and the cam 5 at the bottom of the sheath 3. This prevents the entry of dust or moisture between the sheath 3 and this cam 5.

La première nervure annulaire interne 32, est également clipée entre la collerette 53 et la première nervure annulaire externe 66, permettant ainsi de bloquer en translation la came 5 à l'intérieur du fourreau 3, tout en permettant sa rotation à l'intérieur du fourreau 3, par glissement de cette première nervure annulaire interne 32 entre la collerette 53 et la première nervure annulaire externe 66.The first internal annular rib 32 is also clipped between the flange 53 and the first external annular rib 66, thus making it possible to block the cam 5 in translation inside the sleeve 3 while allowing it to rotate inside the sheath 3, by sliding of this first internal annular rib 32 between the flange 53 and the first external annular rib 66.

Selon l'invention et comme ici, la portion d'actionnement 58 peut être entrainée en rotation par l'utilisateur via la base 7. Pour améliorer cet entrainement en rotation, la portion d'actionnement 58 peut comprendre des nervures longitudinales 69, renforçant l'emmanchement dans la base 7.According to the invention and as here, the actuating portion 58 can be rotated by the user via the base 7. To improve this rotational drive, the actuating portion 58 may comprise longitudinal ribs 69, reinforcing the in the base 7.

Selon l'invention et comme ici, selon l'axe longitudinal A de la came 5, la première nervure annulaire externe 66 et la deuxième nervure annulaire externe 68 peuvent être agencées à distance de manière à loger entre elles une nervure annulaire interne 71 ménagée sur la paroi interne de la base 7 et en haut de celle-ci, de manière à cliper la bordure supérieur de la base 7 en vis-à-vis de la bordure inférieure du fourreau 3, comme illustré en figure 4, avec un léger jeu pour permettre la rotation de la base 7 par rapport au fourreau 3.According to the invention and as here, along the longitudinal axis A of the cam 5, the first outer annular rib 66 and the second outer annular rib 68 may be arranged at a distance so as to accommodate between them an internal annular rib 71 formed on the inner wall of the base 7 and at the top thereof, so as to clip the upper edge of the base 7 vis-à-vis the lower edge of the sheath 3, as shown in FIG. figure 4 , with a slight clearance to allow rotation of the base 7 relative to the sheath 3.

Ainsi le fourreau 3, la came 5 et la base 7 sont assemblés ensembles, le mouvement en translation de la base est bloqué, la base restant libre en rotation solidairement de la portion d'actionnement 58.Thus the sheath 3, the cam 5 and the base 7 are assembled together, the translational movement of the base is blocked, the base remaining free to rotate integrally with the actuating portion 58.

La portion mâle 50 s'étend également en longueur entre une première extrémité 59 et une deuxième extrémité 59', et selon un axe longitudinal qui correspond à l'axe longitudinal A du dispositif d'application 1.The male portion 50 also extends in length between a first end 59 and a second end 59 ', and along a longitudinal axis which corresponds to the longitudinal axis A of the application device 1.

La première extrémité 59 et la deuxième extrémité 59' sont respectivement à l'extérieur et à l'intérieur de la portion femelle 40 en position déployée, comme on peut le voir en figure 3.The first end 59 and the second end 59 'are respectively outside and inside the female portion 40 in the deployed position, as can be seen in FIG. figure 3 .

Le long et tout autour de la portion mâle 50 sont agencées une première et une deuxième rainures hélicoïdales 57a, 57b formant chacune une forme externe agencée de manière à coopérer avec une forme interne en croissant de lune 47a, 47b correspondante. En particulier dans cet exemple, la portion mâle 50 forme une portion filetée avec un double filetage, chaque rainure hélicoïdale 57a, 57b étant formée par le fond d'un filet distinct 56a, 56b réparti tout au long de la portion mâle 50.Long and all around the male portion 50 are arranged first and second helical grooves 57a, 57b each forming an outer shape arranged to cooperate with an internal crescent shape 47a, 47b corresponding. In particular in this example, the male portion 50 forms a threaded portion with a double thread, each helical groove 57a, 57b being formed by the bottom of a separate thread 56a, 56b distributed along the male portion 50.

La première forme externe en croissant de lune 47a est inclinée par rapport à l'axe longitudinal A de la came 5 de manière à venir se loger à l'intérieur de la première rainure hélicoïdale 57a. La deuxième forme externe en croissant de lune 47b est inclinée par rapport à l'axe longitudinal A de la came 5 de manière à venir se loger à l'intérieur de une deuxième rainure hélicoïdale 57b. Ainsi la portion mâle 50 peut être vissée ou dévissée à l'intérieur de la portion femelle 40.The first crescent-shaped outer shape 47a is inclined with respect to the longitudinal axis A of the cam 5 so as to be housed inside the first helical groove 57a. The second outer crescent shape 47b is inclined relative to the longitudinal axis A of the cam 5 so as to be housed inside a second helical groove 57b. Thus the male portion 50 can be screwed or unscrewed inside the female portion 40.

La rotation de la came 5 entraîne la rotation de les formes externes en croissant de lune 47a, 47b et donc leur coopération avec les filets correspondant 56a, 56b, entrainant de ce fait le déplacement hélicoïdal de la portion mâle 50 dans la portion femelle 40, et donc le déplacement de la cupule 4 par glissement le long et à l'intérieur du fourreau 3. La cupule 4 évolue ainsi entre sa position déployée et sa position rétractée, dans un sens ou dans l'autre, selon le sens de rotation de la came 5.The rotation of the cam 5 causes the rotation of the crescent-shaped external forms 47a, 47b and therefore their cooperation with the corresponding threads 56a, 56b, thereby causing the helical displacement of the male portion 50 in the female portion 40, and thus the displacement of the cup 4 by sliding along and inside the sleeve 3. The cup 4 thus evolves between its deployed position and its retracted position, in one direction or the other, depending on the direction of rotation of the the cam 5.

Selon des réalisations non représentées, les formes coopérant pour entrainer le vissage ou le dévissage des portions mâle et femelle peuvent comprendre au moins une rainure formée par une glissière dans ou une fente hélicoïdale au travers de la paroi enveloppante et au moins un tenon radial porté par la portion mâle, l'évolution du tenon dans la rainure entrainant le vissage ou le dévissage.According to embodiments not shown, the forms cooperating to drive the screwing or unscrewing of the male and female portions may comprise at least one groove formed by a slide in or a helical slot through the wrapping wall and at least one radial pin carried by the male portion, the evolution of the post in the groove causing the screwing or unscrewing.

Dans cet exemple, la collerette 53 présente une face tournée du côté de la portion mâle 50, au moins un pion, dans cet exemple deux pions 54a, 54b. Cette face est dans cet exemple la face supérieure de la collerette 53.In this example, the collar 53 has a face turned towards the male portion 50, at least one pin, in this example two pins 54a, 54b. This face is in this example the upper face of the flange 53.

Les figures 9a à 9c illustrent la cupule 4 et la came 5 assemblées, en différentes positions.The Figures 9a to 9c illustrate the cup 4 and the cam 5 assembled, in different positions.

Pour réaliser cet assemblage, il n'est pas nécessaire de visser la cupule 4 dans la came 5. En effet, les deux portions flexibles 44a, 44b, peuvent s'écarter l'une de l'autre en enfonçant la portion mâle 50 dans la portion femelle 40, par pression du double filetage 56a/56b contre les formes internes en croissant de lune 47a, 47b. On peut ainsi simplement enfoncer la came 5 dans la cupule 4, jusqu'à ce que ces pièces viennent en butée, en plaçant chaque pion 54a, 54b dans le logement 64a, 64b. Cela facilite d'autant plus le montage si le raisin est déjà monté sur la zone de réception 42.To achieve this assembly, it is not necessary to screw the cup 4 into the cam 5. Indeed, the two flexible portions 44a, 44b can move away from each other by pressing the male portion 50 in the female portion 40, by pressing the double thread 56a / 56b against the crescent-shaped internal forms 47a, 47b. It is thus possible to simply push the cam 5 into the cup 4, until these parts come into abutment, placing each pin 54a, 54b in the housing 64a, 64b. This facilitates all the more mounting if the grape is already mounted on the reception area 42.

Ces pions 54a, 54b présentent une certaine rigidité, à savoir qu'arrivés chacun en contact avec l'un des bords escamotables 60a, 60b, ils entrainent la déformation de ce dernier.These pins 54a, 54b have a certain rigidity, namely that each come into contact with one of the retractable edges 60a, 60b, they cause the deformation of the latter.

En étant situé sur la face de la collerette 53 agencée en vis-à-vis de la tranche formant la bordure périphérique 46, soit ici sous la collerette 53, lorsque la portion femelle 40 est vissée à fond sur et autour de la portion mâle 50, chaque pion 54a, 54b rentre en contact avec la tranche inférieure du doigt escamotable 60a, 60b.Being located on the face of the flange 53 arranged vis-à-vis the edge forming the peripheral edge 46, here under the flange 53, when the female portion 40 is screwed fully on and around the male portion 50 each pin 54a, 54b comes into contact with the lower edge of the retractable finger 60a, 60b.

De la figure 9a à la figure 9c, la cupule 4 et la came 5 évoluent en vissage.Of the figure 9a to the Figure 9c , the cup 4 and the cam 5 evolve in screwing.

En figure 9a, la cupule 4 est positionnée à un pas de vis V avant la fin du vissage.In figure 9a , the cup 4 is positioned at a thread V before the end of the screwing.

Chaque pion 54a, 54b ainsi que le doigt escamotable 60a, 60b correspondant et le logement correspondant 64a, 64b sont agencés de manière à ce qu'en fin de vissage, chaque pion 54a, 54b entre en contact avec le doigt escamotable 60a, 60b correspondant, comme on peut le voir en figure 9b.Each pin 54a, 54b and the retractable finger 60a, 60b corresponding and the corresponding housing 64a, 64b are arranged so that at the end of screwing, each pin 54a, 54b comes into contact with the retractable finger 60a, 60b corresponding as can be seen in figure 9b .

Puis, en poursuivant le vissage, chaque pion 54a, 54b crée une pression sur le doigt escamotable, déformant celui-ci vers l'intérieur de l'échancrure 63a, 63b correspondante. Ainsi, chaque doigt escamotable est mis sous contrainte et quitte sa forme initiale pour évoluer vers une forme contrainte. De ce fait, chaque bord escamotable 60a, 60b s'escamote et permet au pion correspondant 54a, 54b de rentrer dans le logement correspondant 64a, 64b.Then, continuing the screwing, each pin 54a, 54b creates a pressure on the retractable finger, deforming it inwardly of the notch 63a, 63b corresponding. Thus, each retractable finger is put under stress and leaves its initial shape to evolve to a constrained form. Therefore, each retractable edge 60a, 60b retracts and allows the corresponding pin 54a, 54b to enter the corresponding housing 64a, 64b.

Comme on peut le voir en figures 9c et 10, lorsque le vissage est complet, chaque pion 54a, 54b est logé à l'intérieur du logement correspondant 64a, 64b, et le doigt escamotable 60a, 60b, reprend sa forme initiale, en arrière du pion 54a, 54b selon le sens de vissage. Le vissage est terminé.As we can see in Figures 9c and 10 when the screwing is complete, each pin 54a, 54b is housed inside the corresponding housing 64a, 64b, and the retractable finger 60a, 60b, resumes its original shape, behind the pin 54a, 54b in the direction of screwing . The screwing is finished.

De ce fait, en fin de vissage l'utilisateur sent dans un premier temps une légère résistance (figure 10b), puis une fin brusque de résistance (figure 10c). Ceci lui indique que le vissage est terminé. L'utilisateur a donc une information précise de la fin du vissage.Therefore, at the end of screwing the user feels at first a slight resistance ( figure 10b ), then a sudden end of resistance ( figure 10c ). This tells him that screwing is complete. The user therefore has precise information of the end of the screwing.

Selon l'invention, et comme dans cet exemple, chaque pion 54, 54b peut présenter une largeur, c'est-à-dire la dimension prise selon un axe orthogonal à celui de l'axe longitudinal A de la portion mâle 50, voisine ou sensiblement égale à la largeur du logement correspondant 64a, 64b. Cela permet d'éviter un jeu entre la cupule 4 et la came 5 et de ce fait entre le fourreau 3 et sa base 7 une fois le vissage terminé.According to the invention, and as in this example, each pin 54, 54b may have a width, that is to say the dimension taken along an axis orthogonal to that of the longitudinal axis A of the male portion 50, adjacent or substantially equal to the width of the corresponding housing 64a, 64b. This avoids a gap between the cup 4 and the cam 5 and thus between the sleeve 3 and its base 7 once the screwing is complete.

Dans l'exemple illustré, cette largeur est de 1,5 millimètres (mm).In the illustrated example, this width is 1.5 millimeters (mm).

Chaque logement 64a, 64b est délimité, dans le sens du vissage, en avant par le bord escamotable correspondant 60a, 60b, et en arrière par un bord arrière 65a.Each housing 64a, 64b is delimited, in the screwing direction, forward by the corresponding retractable edge 60a, 60b, and back by a rear edge 65a.

Selon l'invention, et comme dans cet exemple, la tranche inférieure 77a de chaque doigt escamotable 60a, 60b peut être à un niveau qui, selon l'axe longitudinal A de la portion femelle 40, se situe en dessus du reste de la tranche formant la bordure périphérique 46. Cela facilite l'entrée et la sortie du pion 54a, 54b du logement 64a, 64b correspondant.According to the invention, and as in this example, the lower edge 77a of each retractable finger 60a, 60b can be at a level which, along the longitudinal axis A of the female portion 40, is above the rest of the slice forming the peripheral edge 46. This facilitates the entry and exit of the pin 54a, 54b of the housing 64a, 64b corresponding.

De ce fait, la profondeur p1 de chaque logement 64a, 64b selon une direction longitudinale est inférieure du côté du bord escamotable 60a, 60b à celle p2 du côté du bord arrière 65a. Cela améliore le blocage en vissage. Dans l'exemple illustré, la profondeur p1 du côté du bord escamotable 60a, 60b est environ de 0,65 mm, et la profondeur p2 du côté du bord arrière 65a est d'environ 1mm.Therefore, the depth p1 of each housing 64a, 64b in a longitudinal direction is lower on the side of the retractable edge 60a, 60b to that p2 on the side of the rear edge 65a. This improves the locking screw. In the example shown, the depth p1 on the side of the retractable edge 60a, 60b is about 0.65 mm, and the depth p2 on the side of the rear edge 65a is about 1mm.

Selon l'invention, et comme dans cet exemple, le bord arrière 62a, 62b des doigts escamotables peut être arrondi, permettant lors du dévissage de diminuer l'effort sur le bord escamotable 60a. Dans l'exemple illustré, le bord arrière forme un quart de disque de 0,5 mm de rayon.According to the invention, and as in this example, the rear edge 62a, 62b retractable fingers can be rounded, allowing during the unscrewing to reduce the force on the retractable edge 60a. In the illustrated example, the rear edge forms a quarter disc of 0.5 mm radius.

Selon l'invention, la zone déformable peut comprendre le relief de vissage, ici la forme interne 47a, 47b en forme de croissant de lune. Cela peut être réalisé à la place de réaliser le bord escamotable 60a, 60b de manière déformable, ou en complément de celui-ci.According to the invention, the deformable zone may comprise the screw-in relief, here the internal shape 47a, 47b in the shape of a crescent moon. This can be done instead of making the retractable edge 60a, 60b deformably, or in addition to it.

Dans l'exemple illustré, c'est ce dernier cas qui est mis en œuvre. Ainsi, en plus de la déformation du doigt escamotable 60a, 60b, chacune desdites portions flexibles 44a, 44b forme une zone déformable susceptible de s'écarter sur les côtés du dispositif d'application 1. Comme on peut le voir en figures 5 et 6, chaque portion flexible 44a, 44b comprend l'un des reliefs de vissage 47a, 47b.In the illustrated example, it is this last case which is implemented. Thus, in addition to the deformation of the retractable finger 60a, 60b, each of said flexible portions 44a, 44b form a deformable zone that can deviate on the sides of the application device 1. As can be seen in Figures 5 and 6 each flexible portion 44a, 44b comprises one of the screw-in reliefs 47a, 47b.

Les filets 56a, 56b et les zones déformables sont agencés de manière à ce que la pression des pions 54a, 54b sur les bords escamotables 60a, 60b entraine la compression de chaque relief de vissage 47a, 47b contre un flanc 78a du filetage 56a, 56b avec lequel il se visse, ce flanc 78a étant orienté en direction du pion correspondant 54a, 54b. Ce flanc est appelé ci-après flanc de jeu 78a.The threads 56a, 56b and the deformable zones are arranged in such a way that the pressure of the pins 54a, 54b on the retractable edges 60a, 60b causes the compression of each screwing relief 47a, 47b against a flank 78a of the threads 56a, 56b. with which it is screwed, the flank 78a being oriented towards the corresponding pin 54a, 54b. This flank is hereinafter referred to as the game flank 78a.

Chaque flanc de jeu 78a relie le fond 57a du filetage correspondant 56a au sommet 79a de ce filetage 56a.Each game flank 78a connects the bottom 57a of the corresponding thread 56a to the top 79a of the thread 56a.

Cette compression entraine à la fois :

  • la déformation de la zone élastiquement déformable 44a, 44b, et
  • l'écartement selon une composante radiale des reliefs de vissage 47a, 47b,
  • le glissement de ceux-ci contre le flanc de jeu 78a correspondant, et du fond 57a, 57b du filet correspondant 56a, 56b vers le sommet 79a correspondant.
This compression leads to both:
  • the deformation of the elastically deformable zone 44a, 44b, and
  • the spacing according to a radial component of the screw-in reliefs 47a, 47b,
  • the sliding thereof against the corresponding play flank 78a, and the bottom 57a, 57b of the corresponding thread 56a, 56b to the corresponding vertex 79a.

Comme chaque pion 54a, 54b pousse le bord escamotable 60a, 60b et donc la cupule 4 vers le haut. L'écartement des portions flexibles 44a, 44b permet l'écartement des reliefs de vissage 47a, 47b l'un de l'autre de part et d'autre de l'axe longitudinal A, et donc permet la remontée de la cupule vers le haut.As each pin 54a, 54b pushes the retractable edge 60a, 60b and thus the cup 4 upwards. The spacing of the flexible portions 44a, 44b allows the spacing of the screwing reliefs 47a, 47b from each other on either side of the longitudinal axis A, and thus allows the rise of the cup towards the above.

Ainsi, la portion femelle 40 et le bord escamotable 60a, 60b se déplacent en retrait par rapport aux pions 54a, 54b. La poursuite du vissage peut donc se faire de sorte que chaque pion puisse se placer en vis-à-vis du logement correspondant 64a, 64b.Thus, the female portion 40 and the retractable edge 60a, 60b move back with respect to the pins 54a, 54b. The continuation of the screwing can therefore be done so that each pin can be placed vis-à-vis the corresponding housing 64a, 64b.

Les portions flexibles 64a, 64b, génèrent d'une force de rappel radiale des reliefs de vissage 47a, 47b. Par réaction sur le flanc de jeu 78a, et compte tenu de l'orientation de ce dernier, les reliefs de vissage 47a, 47b sont donc rappelés vers le fond 57a, 57b du filet correspondant 56a, 56b, donc en direction du pion 54a, 54b.The flexible portions 64a, 64b generate a radial restoring force of the screw-in reliefs 47a, 47b. By reaction on the game flank 78a, and taking into account the orientation of the latter, the screwing reliefs 47a, 47b are thus returned to the bottom 57a, 57b of the corresponding thread 56a, 56b, thus in the direction of the peg 54a, 54b.

Ainsi, lorsque chaque pion 54a, 54b se place en vis-à-vis du logement correspondant 64a, 64b, ce dernier est rappelé vers le pion et vient l'entourer, la cupule 4 étant alors dans sa position rétractée.Thus, when each pin 54a, 54b is placed vis-à-vis the corresponding housing 64a, 64b, the latter is returned to the pin and surrounds it, the cup 4 is then in its retracted position.

Ce dispositif d'application 1 met donc en œuvre également un jeu sur les filetages pour améliorer le clipage des pions dans les logements.This application device 1 also implements a game on the threads to improve the clipping of the pawns in the housing.

La tranche inférieure 77a présente une inclinaison telle que la distance entre le bord d'attaque 61a et la première extrémité 59 de la portion mâle 50 soit plus grande que la distance entre le bord arrière 62a et la première extrémité de la portion mâle. De ce fait, cela favorise la poussée de la portion femelle 40 vers le haut lors de l'entrée en contact du pion 54a, 54b et de la poursuite du vissage.The lower edge 77a has an inclination such that the distance between the leading edge 61a and the first end 59 of the male portion 50 is greater than the distance between the rear edge 62a and the first end of the male portion. As a result, it promotes the thrust of the female portion 40 upwards when the pin 54a, 54b comes into contact and the screwing continues.

Dans cet exemple, cette inclinaison est d'un angle α d'environ 15°.In this example, this inclination is of an angle α of about 15 °.

Selon l'invention, comme dans cet exemple, chaque logement 64a, 64b peut être moins profond que la hauteur h du pion correspondant 54a, 54b. Dans ce cas, en fin de vissage, le fond du logement est en appui contre le pion correspondant. Cela renforce la sensation de fin de vissage. De plus, lors du rappel de la portion femelle 40 vers la collerette 53, cela permet de créer le son d'un clipage.According to the invention, as in this example, each housing 64a, 64b may be less deep than the height h of the corresponding pin 54a, 54b. In this case, at the end of screwing, the bottom of the housing is in abutment against the corresponding pin. This reinforces the feeling of end of screwing. Moreover, when the female portion 40 is returned to the flange 53, this makes it possible to create the sound of a clipping.

Dans ce dernier cas, le bord arrière forme un bord de butée 65a, contre lequel vient en butée le pion correspondant 54a, 54b en fin de vissage.In the latter case, the rear edge forms an abutment edge 65a, against which abuts the corresponding pin 54a, 54b at the end of screwing.

Selon l'invention et comme dans l'exemple illustré, la forme en croissant de lune du relief de vissage 47a, 47b peut être jointive avec l'échancrure 63a, 63b, notamment sa portion transversale 73a, comme on peut le voir en figures 5, 6 et 11. Cela favorise l'écartement des reliefs de vissage 47a, 47b.According to the invention and as in the example illustrated, the crescent shape of the screwing relief 47a, 47b may be contiguous with the notch 63a, 63b, in particular its transverse portion 73a, as can be seen in FIG. Figures 5, 6 and 11 . This favors the spacing of the screw reliefs 47a, 47b.

Les moyens de guidage 45a, 45b présentent un léger jeu avec la paroi interne du fourreau 3 permettant cet écartement, tout en limitant celui-ci.The guide means 45a, 45b have a slight clearance with the inner wall of the sleeve 3 allowing this spacing, while limiting it.

Selon l'invention et comme dans l'exemple illustré, le sommet du relief de vissage 47a, 47b juste au-dessus de la portion transversale 73a de l'échancrure correspondante 63a, 63b peut être à une distance h1 du fond du logement correspondant égale à un demi pas de vis V.According to the invention and as in the illustrated example, the top of the screw-in relief 47a, 47b just above the transverse portion 73a of the corresponding notch 63a, 63b can be at a distance h1 from the bottom of the corresponding corresponding housing. at half a screw V.

Par exemple, le fond 57b du deuxième filet 56b passe ici au-dessus et de manière adjacente au haut du premier pion 54a. Le fond 57a du premier filet au-dessus de ce premier pion 54a est donc à un demi pas de vis V, le premier relief de vissage 47a étant donc logé dans ce premier filet à l'aplomb du logement en fin de vissage. De ce fait, chaque relief de vissage 47a, 47b est agencé au plus près du logement 64a, 64b au-dessus duquel il est agencé.For example, the bottom 57b of the second net 56b passes here above and adjacent the top of the first pin 54a. The bottom 57a of the first net above this first pin 54a is therefore at half a screw pitch V, the first screwing relief 47a is thus housed in the first thread in line with the housing at the end of screwing. Therefore, each screwing relief 47a, 47b is arranged closer to the housing 64a, 64b above which it is arranged.

Selon des réalisations non représentées, la portion femelle est formée sur la came à la place de la partie mâle 50 et de la collerette 53. L'orifice d'entrée est alors agencé en haut. Un épaulement est prévu à la place de la collerette 53 en dessous de la paroi enveloppante pour permettre de cliper la première nervure annulaire interne 32, ménagée sur la paroi interne du fourreau 3, entre cet épaulement et la première nervure externe annulaire 66. La portion mâle et la collerette sont dans ce cas formées sur la cupule à la place de la paroi enveloppante 40. Cela permet un vissage et un dévissage de la même manière que précédemment décrit.According to embodiments not shown, the female portion is formed on the cam in place of the male portion 50 and the flange 53. The inlet is then arranged at the top. A shoulder is provided in place of the flange 53 below the wrapping wall to allow to clip the first inner annular rib 32, formed on the inner wall of the sheath 3, between this shoulder and the first annular outer rib 66. The male portion and the collar are in this case formed on the cup to the place of the enveloping wall 40. This allows a screwing and unscrewing in the same manner as previously described.
