La présente invention concerne plus particulièrement le domaine des dispositifs de conditionnement et de distribution d'un stick de produit tel qu'un rouge à lèvres, un fond de teint, un fard à paupières, un fard à joues, un correcteur de teint, une composition traitante, lavante ou hydratante, un déodorant, ou encore un produit de soin capillaire.The present invention relates more particularly to the field of devices for packaging and dispensing a product stick such as a lipstick, a foundation, an eyeshadow, a blush, a concealer, a complexion treatment, washing or moisturizing composition, a deodorant, or a hair care product.

De tels sticks sont généralement conditionnés dans des dispositifs du type pourvu d'une cupule pour le support dudit stick mobile à l'intérieur d'un fourreau, d'une enveloppe entourant le fourreau, et d'un manchon extérieur entourant l'enveloppe. Des moyens d'entraînement de la cupule sont également prévus pour permettre, lors d'une rotation d'un organe d'actionnement lié à l'enveloppe, son déplacement axial à l'intérieur du fourreau entre une position de stockage et une position d'utilisation du stick. Les moyens d'entraînement peuvent notamment être réalisés sous la forme d'ergots prévus sur la cupule et le fourreau et coopérant avec des rainures ménagées sur l'enveloppe, le fourreau et sur le manchon extérieur. Pour plus de détails, on pourra par exemple se référer au brevet américain 6,056,465.Such sticks are generally packaged in devices of the type provided with a cup for supporting said mobile stick inside a sheath, a casing surrounding the sheath, and an outer sleeve surrounding the casing. Cup drive means are also provided to allow, during a rotation of an actuating member connected to the casing, its axial displacement inside the sheath between a storage position and a position of the casing. use of the stick. The drive means may in particular be made in the form of lugs provided on the cup and the sleeve and cooperating with grooves provided on the casing, the sheath and the outer sleeve. For more details, we can for example refer to the US patent 6,056,465.

Le stick de produit est généralement consommé de façon relativement rapide et le dispositif est jeté quand le stick est fini. Dès lors, les éléments constituant le dispositif sont fabriqués à moindre coût par moulage de matières synthétiques économiques.The product stick is usually consumed relatively quickly and the device is thrown when the stick is finished. Therefore, the elements constituting the device are manufactured cheaply by molding of synthetic materials economic.

Or, le manchon extérieur et l'organe d'actionnement du dispositif de ce brevet sont visibles depuis l'extérieur pour l'utilisateur.However, the outer sleeve and the actuating member of the device of this patent are visible from the outside for the user.

Ce dispositif n'est donc pas adapté à une application de type luxe. En effet, dans une telle application, l'utilisation de matières synthétiques à faible coût peut favoriser une appréciation négative de l'utilisateur.This device is not suitable for a luxury type application. Indeed, in such an application, the use of low cost synthetic materials can promote a negative appreciation of the user.

Par ailleurs, compte tenu des dimensions des sticks cosmétiques classiquement conditionnés, la taille du dispositif est relativement réduite, ce qui peut être gênant lors de sa prise en main et lors de la rotation de l'organe d'actionnement en vue de la distribution du produit.Moreover, given the size of conventionally packaged cosmetic sticks, the size of the device is relatively small, which can be inconvenient during its handling and during the rotation of the actuating member for the distribution of the device. product.

On connaît également, par le document WO 2007/066855 , un dispositif de conditionnement et de distribution d'un stick de rouge à lèvres comprenant un ensemble de distribution formé d'une cupule de support du stick, d'un fourreau à l'intérieur duquel est monté la cupule, d'une enveloppe entourant ledit fourreau et d'un manchon extérieur entourant l'enveloppe et mobile en rotation par rapport à ladite enveloppe. Le fourreau comporte un ergot traversant une rainure longitudinale ménagée sur l'enveloppe et pénétrant dans une première rainure hélicoïdale du manchon. La cupule comporte quant à elle un ergot traversant une rainure de l'enveloppe opposée à la rainure et pénétrant dans une rainure longitudinale du fourreau et dans une seconde rainure hélicoïdale du manchon. Le dispositif comporte également un étui pour l'ensemble de distribution constitué d'un corps rotatif monté sur l'enveloppe, d'un capot tubulaire et d'un volet d'obturation monté sur ledit capot.It is also known from the document WO 2007/066855 , a device for packaging and dispensing a lipstick stick comprising a dispensing assembly formed of a cup for supporting the stick, a sleeve inside which is mounted the cup, an envelope surrounding said sheath and an outer sleeve surrounding the casing and rotatable relative to said casing. The sleeve comprises a lug through a longitudinal groove formed on the casing and penetrating into a first helical groove of the sleeve. The cup comprises a lug passing through a groove of the casing opposite to the groove and penetrating into a longitudinal groove of the sheath and into a second helical groove of the sleeve. The device also comprises a case for the dispensing assembly consisting of a rotational body mounted on the casing, a tubular hood and a shutter mounted on said cover.

On connaît encore, par le document CA 1 331 965 , un dispositif de conditionnement et de distribution d'un stick de rouge à lèvres comportant une cupule de support du stick, un fourreau à l'intérieur duquel est montée la cupule, une enveloppe entourant le fourreau et un manchon extérieur entourant l'enveloppe et mobile en rotation par rapport à ladite enveloppe. Le dispositif comporte également des tubes formant un étui pour l'ensemble de distribution du stick, un des tubes étant apte à entraîner en rotation le manchon extérieur. Pour permettre le déplacement axial de la cupule, le manchon extérieur comporte une protubérance s'étendant radialement vers l'intérieur et coopérant avec une rainure hélicoïdale de l'enveloppe.We still know, by the document CA 1,331,965 , a device for packaging and dispensing a lipstick stick comprising a stick support cup, a sleeve inside which is mounted the cup, an envelope surrounding the sleeve and an outer sleeve surrounding the envelope and mobile in rotation with respect to said envelope. The device also comprises tubes forming a holster for the dispensing assembly of the stick, one of the tubes being able to rotate the outer sleeve. To allow the axial displacement of the cup, the outer sleeve has a protuberance extending radially inward and cooperating with a helical groove of the envelope.

Avec les dispositifs décrits dans ces deux derniers documents, lorsque le manchon extérieur est entraîné en rotation par l'organe d'actionnement associé, il existe un mouvement relatif de rotation entre le stick de rouge à lèvres et la partie supérieure de l'étui. Dès lors, si l'on utilise un stick et un étui comprenant chacun une extrémité supérieure biseautée, ces deux extrémités ne sont pas toujours parallèles dans les positions d'utilisation du stick.With the devices described in these last two documents, when the outer sleeve is rotated by the associated actuating member, there is a relative rotational movement between the lipstick stick and the upper part of the case. Therefore, if using a stick and a case each comprising a beveled upper end, these two ends are not always parallel in the use of the stick positions.

Dans ces conditions, l'utilisatrice ne sait pas comment positionner la partie supérieure de l'étui par rapport à la surface à traiter avant la sortie du stick hors de l'étui.Under these conditions, the user does not know how to position the upper part of the case relative to the surface to be treated before the release of the stick out of the case.

La présente invention a donc pour but de remédier aux inconvénients des dispositifs antérieurs.The present invention therefore aims to overcome the disadvantages of prior devices.

Plus particulièrement, la présente invention vise à prévoir un dispositif de conditionnement et de distribution d'un stick de produit, notamment d'un produit cosmétique, qui puisse être aisément pris en main, manipulé et être adapté à une application de type luxe.More particularly, the present invention aims at providing a device for packaging and dispensing a product stick, in particular a cosmetic product, which can be easily handled, handled and adapted to a luxury type application.

La présente invention a également pour but de prévoir un dispositif facile à fabriquer, économique et pouvant être transporté sans risque de détérioration des éléments permettant la distribution de produit.The present invention also aims to provide a device easy to manufacture, economical and can be transported without risk of deterioration of the elements for product distribution.

La présente invention a encore pour but de prévoir un dispositif adapté pour permettre à l'utilisateur de savoir, avant la sortie du produit, comment positionner le dispositif par rapport à la surface à traiter de façon à obtenir ensuite, après la sortie du produit, l'orientation souhaitée de l'extrémité supérieure dudit produit par rapport à la surface à traiter. Selon l'invention, le dispositif de conditionnement et de distribution d'un stick de produit, comporte les caractéristiques de la revendication 1. L'étui de protection peut aisément être réalisé dans un matériau adapté à une application de type luxe, par exemple un matériau métallique et pouvant comporter des décorations, des pictogrammes ou encore une marque, tout en conservant un ensemble de distribution tel qu'il est revendiqué à la revendication 1, ledit ensemble de distribution pouvant être ainsi fabriqué à partir de matériaux à faible coût. Ainsi, il est possible de prévoir un habillage adapté à une application de type luxe pour cet ensemble de distribution sans augmenter le coût de revient dudit ensemble. Une fois que le produit a été entièrement utilisé par le consommateur, l'étui de protection peut être conservé de manière à être réutilisé avec un autre ensemble de distribution de conception similaire formant recharge de l'étui.The present invention also aims to provide a device adapted to allow the user to know, before the product is released, how to position the device relative to the surface to be treated so as to obtain after the product is released, the desired orientation of the upper end of said product relative to the surface to be treated. According to the invention, the device for packaging and dispensing a product stick has the features of claim 1. The protective case can easily be made of a material suitable for a luxury type application, for example a metallic material and may include decorations, pictograms or a brand, while maintaining a distribution set as it is claimed in claim 1, said dispensing assembly being thus capable of being made from low cost materials. Thus, it is possible to provide a dressing adapted to a luxury type of application for this distribution set without increasing the cost price of said set. Once the product has been fully used by the consumer, the protective case may be retained for reuse with another similarly designed dispensing unit forming the case refill.

Par ailleurs, l'étui de protection permet d'augmenter l'épaisseur du dispositif, et plus généralement son encombrement, ce qui facilite sa prise en main et son actionnement en vue de la distribution du produit.Furthermore, the protective case increases the thickness of the device, and more generally its size, which facilitates its grip and its actuation for the distribution of the product.

La conception du dispositif, et notamment la prévision sur l'enveloppe du moyen de guidage coopérant avec la rainure du fourreau, permet de conserver l'orientation ou indexation du produit relativement à la partie supérieure de l'étui de protection lors de son déplacement de la position de stockage vers la ou les positions d'utilisation. En effet, lors du déplacement de la cupule de support, le produit ne se déplace pas en rotation relativement à la partie supérieure de l'étui de protection, notamment relativement à un capot de l'étui. Il n'existe donc pas de mouvement relatif de rotation entre le produit et la partie supérieure de l'étui de protection. Le moyen de guidage prévu sur l'enveloppe et coopérant avec la rainure du fourreau permet donc d'obtenir un guidage de la cupule de support et du produit relativement à la partie supérieure de l'étui de protection uniquement ou exclusivement en translation.The design of the device, and in particular the provision on the casing of the guiding means co-operating with the groove of the sheath, makes it possible to maintain the orientation or indexing of the product relative to the upper part of the protective sheath during its movement from the storage position towards the position or positions of use. Indeed, during the displacement of the support cup, the product does not move in rotation relative to the upper part of the protective case, in particular relative to a hood of the case. There is therefore no relative movement of rotation between the product and the upper part of the protective case. The guide means provided on the casing and cooperating with the groove of the sheath thus makes it possible to obtain guiding of the support cup and the product relative to the upper part of the protective casing solely or exclusively in translation.

Ainsi, le produit et l'étui comprenant chacun une extrémité supérieure biseautée, le dispositif permet de conserver l'orientation relative de ces deux extrémités supérieures lors du passage de la position de stockage du produit vers la ou les positions d'utilisation. Avant la sortie du produit, l'utilisatrice sait donc comment positionner l'extrémité supérieure de l'étui de protection par rapport à la surface à traiter de manière à obtenir ensuite, dans la position de sortie du produit, l'orientation souhaitée de l'extrémité supérieure du produit par rapport à cette surface à traiter.Thus, the product and the case each comprising a beveled upper end, the device keeps the relative orientation of these two upper ends during the passage of the product storage position to the position or use. Before leaving the product, the user therefore knows how to position the upper end of the protective case relative to the surface to be treated so as to then obtain, in the product outlet position, the desired orientation of the product. upper end of the product with respect to this surface to be treated.

Avantageusement, l'ensemble de distribution est monté de manière amovible dans l'étui de protection.Advantageously, the dispensing assembly is removably mounted in the protective case.

L'organe d'actionnement forme avantageusement une embase pour le montage d'au moins une partie du manchon extérieur. L'organe d'actionnement comporte des moyens d'entraînement en rotation aptes à coopérer avec des moyens d'entraînement complémentaires du manchon extérieur. Dans un mode de réalisation, cette coopération s'effectue par complémentarité de forme. Selon l'invention, l'étui de protection comporte un capot à l'intérieur duquel est logé l'ensemble de distribution. Le capot est distinct de l'organe de manoeuvre. Le capot peut venir en appui sur l'organe d'actionnement.The actuating member advantageously forms a base for mounting at least a portion of the outer sleeve. The actuating member comprises rotational drive means adapted to cooperate with complementary drive means of the outer sleeve. In one embodiment, this cooperation is performed by complementarity of form. According to the invention, the protective case comprises a cover inside which is housed the distribution assembly. The hood is distinct from the actuator. The cover can bear on the actuating member.

L'étui de protection peut comporter un volet d'obturation de l'orifice de sortie de l'enveloppe mobile entre une position de fermeture dudit orifice et une position d'ouverture. Le volet d'obturation est de préférence monté à rotation sur le capot. Alternativement, il est possible de prévoir le montage du volet d'obturation par coulissement sur ledit capot.The protective case may comprise a closing shutter of the outlet orifice of the mobile envelope between a closed position of said orifice and an open position. The shutter is preferably rotatably mounted on the hood. Alternatively, it is possible to provide the mounting shutter sliding on said cover.

Le volet d'obturation, l'organe d'actionnement et le capot délimitent une chambre fermée à l'intérieur de laquelle est entièrement logé l'ensemble de distribution. Selon l'invention, le capot comporte une surface supérieure biseautée délimitant un orifice de sortie de l'étui de protection pour le produit. Le produit est conditionné sous forme d'un stick monté dans la cupule de support, le stick comportant également une surface supérieure biseautée qui est parallèle à la surface supérieure biseautée du capot dans la position d'utilisation dudit stick. Le stick de produit et le capot sont fixes en rotation l'un relativement à l'autre, ce qui permet de conserver le parallélisme des deux surfaces.The shutter, the actuating member and the hood define a closed chamber inside which is entirely housed the distribution assembly. According to the invention, the cover has a beveled upper surface delimiting an outlet of the protective case for the product. The product is packaged in the form of a stick mounted in the support cup, the stick also having a beveled upper surface which is parallel to the beveled upper surface of the cover in the position of use of said stick. The product stick and the cover are fixed in rotation relative to one another, which makes it possible to maintain the parallelism of the two surfaces.

De préférence, l'enveloppe comporte une languette flexible supportant le moyen de guidage. Cette disposition permet de faciliter l'assemblage du dispositif lorsque l'enveloppe est réalisée dans un matériau relativement rigide. Dans ce but, de façon additionnelle, l'enveloppe peut être fendue à son extrémité inférieure pour faciliter l'assemblage. L'enveloppe peut également comprendre un moyen d'encliquetage pour la retenue axiale du manchon extérieur sur le fourreau.Preferably, the casing comprises a flexible tongue supporting the guiding means. This arrangement makes it easier to assemble the device when the envelope is made of a relatively rigid material. For this purpose, additionally, the envelope can be split at its lower end to facilitate assembly. The casing may also include a latching means for axial retention of the outer sleeve on the sheath.

Dans un mode de réalisation, la cupule de support comporte une languette flexible supportant le moyen de guidage. Cette disposition permet d'obtenir le montage de la cupule de support à l'intérieur du fourreau sans qu'il soit nécessaire de prévoir sur celui-ci une rainure axiale débouchant à son extrémité inférieure pour permettre le passage du moyen de guidage. Le moyen de guidage de la cupule et/ou de l'enveloppe peut comporter un ergot. La présente invention sera mieux comprise à la lecture de la description détaillée d'un mode de réalisation pris à titre d'exemple nullement limitatif et illustré par les dessins annexés, sur lesquels :

  • les figures 1 à 3 sont des vues extérieures en perspective d'un dispositif de conditionnement et de distribution d'un produit respectivement dans des positions de stockage, de sortie intermédiaire et d'utilisation dudit produit,
  • la figure 4 est une vue en perspective éclatée du dispositif de la figure 1,
  • les figures 5 et 6 sont des vues en coupe du dispositif dans la position de la figure 1,
  • les figures 7 et 8 sont des vues en coupe du dispositif dans la position de la figure 2, et
  • les figures 9 et 10 sont des vues en coupe du dispositif dans la position de la figure 3.
In one embodiment, the support cup has a flexible tongue supporting the guide means. This arrangement makes it possible to obtain the mounting of the support cup inside the sheath without it being necessary to provide an axial groove opening therein at its lower end for allow the passage of the guide means. The guide means of the cup and / or the envelope may comprise a lug. The present invention will be better understood on reading the detailed description of an embodiment taken by way of non-limiting example and illustrated by the appended drawings, in which:
  • the Figures 1 to 3 are external views in perspective of a device for packaging and dispensing a product respectively in storage positions, intermediate outlet and use of said product,
  • the figure 4 is an exploded perspective view of the device of the figure 1 ,
  • the Figures 5 and 6 are sectional views of the device in the position of the figure 1 ,
  • the Figures 7 and 8 are sectional views of the device in the position of the figure 2 , and
  • the Figures 9 and 10 are sectional views of the device in the position of the figure 3 .

Sur les figures 1 à 10, on a représenté un dispositif, désigné par la référence numérique générale 10, et destiné à être utilisé pour le conditionnement et la distribution d'un stick S ou raisin de produit, notamment de produit cosmétique.On the Figures 1 to 10 , there is shown a device, designated by the general reference numeral 10, and intended to be used for packaging and dispensing a stick S or grape product, especially cosmetic product.

Le stick S peut par exemple être un rouge à lèvres ou un produit de soin des lèvres. Toutefois, en conçoit aisément que le dispositif 10 peut également s'appliquer au conditionnement et à la distribution d'un stick d'autres types de produits, par exemple un fond de teint, un fard à paupières, un fard à joues, un correcteur de teint, une composition traitante, lavante ou hydratante, un déodorant, ou encore un produit de soin capillaire. Le dispositif 10 est représenté sur les figures dans une position supposée verticale.The stick S may for example be a lipstick or a lip care product. However, it is easily understood that the device 10 can also be applied to the packaging and dispensing of a stick of other types of products, for example a foundation, an eyeshadow, a blush, a concealer complexion, a treatment, washing or moisturizing composition, a deodorant, or a hair care product. The device 10 is shown in the figures in a supposed vertical position.

Le dispositif 10 comporte un ensemble de distribution 12 du stick S et un étui de protection 14 à l'intérieur duquel est logé ledit ensemble de distribution. L'étui de protection 14 est notamment adapté pour favoriser l'esthétisme du dispositif 10 et faciliter sa prise en main en vue de la distribution du stick S. La section de l'étui de protection 14 peut être définie en fonction de celle de l'ensemble de distribution 12. Elle peut être par exemple circulaire, elliptique, polygonale telle que carrée, rectangulaire, hexagonale, octogonale, etc.The device 10 comprises a distribution assembly 12 of the stick S and a protective case 14 inside which is housed said distribution assembly. The protective case 14 is particularly adapted to promote the aesthetics of the device 10 and facilitate its handling for the distribution of the stick S. The section of the protective case 14 may be defined according to that of the distribution assembly 12. It can be for example circular, elliptical, polygonal such as square, rectangular, hexagonal, octagonal, etc..

L'ensemble de distribution 12 comporte un stick pourvu d'une surface supérieure biseautée, une cupule de support 16 du stick, un fourreau 18 à l'intérieur duquel est montée ladite cupule, une enveloppe 20 entourant le fourreau et comportant, à une extrémité supérieure, une tête 24 délimitant un orifice de sortie 26 pour le stick S. L'ensemble comprend également un manchon 22 extérieur entourant l'enveloppe 20 et mobile en rotation par rapport à celle-ci pour permettre la distribution du stick S au travers de l'orifice de sortie 26.The dispensing assembly 12 comprises a stick provided with a beveled upper surface, a support cup 16 of the stick, a sleeve 18 inside which said cup is mounted, a casing 20 surrounding the sleeve and comprising, at one end upper, a head 24 defining an outlet port 26 for the stick S. The assembly also comprises an outer sleeve 22 surrounding the casing 20 and rotatable relative thereto to allow the distribution of the stick S through the outlet port 26.

La cupule de support 16, le fourreau 18, l'enveloppe 20 et le manchon 22 extérieur s'étendent suivant un axe X-X' vertical. L'axe X-X' est ici sécant à l'orifice de sortie 26, et plus particulièrement orthogonal à celui-ci. Dans ce mode de réalisation, l'axe X-X' forme l'axe longitudinal de l'ensemble de distribution 12, et plus généralement du dispositif 10. La cupule de support 16, le fourreau 18, l'enveloppe 20 et le manchon extérieur 22 peuvent chacun être avantageusement réalisés en une seule pièce par moulage d'une matière thermoplastique, par exemple en acétate de méthylène (POM) ou encore en polyamide (PA). Le fourreau 18 peut également être réalisé en matière métallique, par exemple en aluminium, afin de présenter une rigidité accrue tout en conservant une épaisseur relativement fine.The support cup 16, the sheath 18, the casing 20 and the outer sleeve 22 extend along an axis XX 'vertical. The axis XX 'here intersects the outlet orifice 26, and more particularly orthogonal to this one. In this embodiment, the axis XX 'forms the longitudinal axis of the distribution assembly 12, and more generally the device 10. The support cup 16, the sleeve 18, the envelope 20 and the outer sleeve 22 each may advantageously be made in one piece by molding a thermoplastic material, for example methylene acetate (POM) or polyamide (PA). The sleeve 18 may also be made of metal material, for example aluminum, in order to have increased stiffness while maintaining a relatively thin thickness.

Le fourreau 18, de forme générale tubulaire, comporte un bord supérieur 28 biseauté dont l'inclinaison correspond sensiblement à celle d'une surface biseautée 30 supérieure du stick S. Le bord supérieur 28 délimite un orifice de distribution 32 pour ledit stick. Comme cela sera décrit plus en détail par la suite, pour permettre notamment un déplacement axial de la cupule de support 16 relativement au fourreau 18, des rainures 34, 36 traversantes sont ménagées dans toute l'épaisseur dudit fourreau. La rainure 34 comporte une portion longitudinale 34a s'étendant sensiblement à partir de la mi-hauteur du fourreau 18 axialement vers le bas et prolongée, à une extrémité inférieure, par une extension 34b circonférentielle située axialement au voisinage du bord inférieur du fourreau 18. La rainure 34 présente une forme générale en L. La rainure 36 comporte une portion longitudinale 36a s'étendant axialement vers le bas et prolongée, à une extrémité inférieure, par une extension 36b oblique s'étendant vers le bas. L'extrémité supérieure de la portion longitudinale 36a est décalée axialement par rapport à l'extrémité supérieure de la portion longitudinale 34a. La dimension axiale de la portion longitudinale 36a est ici réduite par rapport à celle de la portion longitudinale 34a. Les rainures 34, 36 sont disposées l'une relativement à l'autre dans le sens circonférentiel de manière que l'extension 34b soit diamétralement opposée par rapport à la portion longitudinale 36a.The sheath 18, of generally tubular shape, has a beveled upper edge 28 whose inclination substantially corresponds to that of an upper bevelled surface of the stick S. The upper edge 28 defines a dispensing orifice 32 for said stick. As will be described in more detail below, to allow in particular an axial displacement of the support cup 16 relative to the sheath 18, grooves 34, 36 through are formed throughout the thickness of said sheath. The groove 34 comprises a longitudinal portion 34a extending substantially from the mid-height of the sleeve 18 axially downwards and extended, at a lower end, by a circumferential extension 34b located axially in the vicinity of the lower edge of the sleeve 18. The groove 34 has a generally L-shaped. The groove 36 has a longitudinal portion 36a extending axially downwards and extended at a lower end by an oblique extension 36b extending downwards. The upper end of the longitudinal portion 36a is axially offset relative to the upper end of the longitudinal portion 34a. The axial dimension of the longitudinal portion 36a is here reduced relative to that of the longitudinal portion 34a. The grooves 34, 36 are arranged relatively to each other in the circumferential direction so that the extension 34b is diametrically opposite to the longitudinal portion 36a.

La cupule de support 16 comporte une paroi de fond 38 radiale prolongée axialement à partir d'un bord de grand diamètre par une portion annulaire 40 s'étendant axialement vers le haut. La portion annulaire 40 se prolonge au-delà de la paroi de fond 38 et forme une jupe 42 s'étendant axialement vers le bas. La jupe 42 et la portion annulaire 40 sont radialement en contact contre l'alésage du fourreau 18. Dans la position de stockage du stick S illustrée aux figures 1, 5 et 6, ledit stick et la cupule de support 16 sont entièrement logés à l'intérieur du fourreau 18. La surface biseautée 30 du stick affleure sensiblement avec le bord supérieur 28 du fourreau 18.The support cup 16 has a radial bottom wall 38 extended axially from a large-diameter edge by an annular portion 40 extending axially upwards. The annular portion 40 extends beyond the bottom wall 38 and forms a skirt 42 extending axially downwardly. The skirt 42 and the annular portion 40 are radially in contact against the bore of the sleeve 18. In the storage position of the stick S illustrated in FIGS. figures 1 , 5 and 6 said stick and the support cup 16 are entirely housed inside the sleeve 18. The beveled surface 30 of the stick is substantially flush with the upper edge 28 of the sleeve 18.

Le stick S vient se loger en partie dans la portion annulaire 40 en étant en appui contre la paroi de fond 38. La cupule forme un siège pour le stick S. Pour favoriser le maintien du stick S à l'intérieur de la portion annulaire 40, il est possible de prévoir des nervures ménagées sur son alésage et dirigées radialement vers l'intérieur. La dimension radiale des nervures peut augmenter progressivement en se déplaçant vers la paroi de fond 38 de manière à permettre un positionnement du stick S par coincement.The stick S is housed partly in the annular portion 40 while bearing against the bottom wall 38. The cup forms a seat for the stick S. To promote the maintenance of the stick S inside the annular portion 40 it is possible to provide ribs formed on its bore and directed radially inwards. The radial dimension of the ribs can increase progressively by moving towards the bottom wall 38 so as to allow positioning of the stick S by jamming.

A partir de l'extrémité inférieure de la jupe 42 s'étendent axialement vers le haut deux fentes 44 axiales délimitant sur la cupule de support 16 une languette 46 qui est flexible dans le sens radial. Un ergot 48 est prévu sur la face extérieure de la languette 46 et s'étend radialement vers l'extérieur. L'ergot 48 traverse radialement la rainure 34 du fourreau 18 en vue du guidage axial de la cupule de support 16 relativement audit fourreau. La languette 46 portant l'ergot 48 facilite le montage par coulissement de la cupule de support 16 à l'intérieur du fourreau 18. En effet, lors de cette opération, la languette 46 permet d'obtenir un déplacement radial vers l'intérieur de l'ergot 48 jusqu'à ce qu'il vienne se loger dans la rainure 34. L'ergot 48 présente ici une forme générale cylindrique. Bien entendu, il est également envisageable de prévoir un ergot de forme générale sensiblement différente ayant par exemple une section transversale symétrique de révolution, notamment polygonale.From the lower end of the skirt 42 extend axially upwards two axial slots 44 delimiting on the support cup 16 a tongue 46 which is radially flexible. A lug 48 is provided on the outer face of the tongue 46 and extends radially outwardly. The lug 48 passes radially through the groove 34 of the sheath 18 for axial guidance of the support cup 16 relative to said sheath. The tongue 46 carrying the lug 48 facilitates the sliding installation of the support cup 16 inside the sleeve 18. In fact, during this operation, the tongue 46 makes it possible to obtain a radial displacement towards the inside of the the lug 48 until it is housed in the groove 34. The lug 48 here has a generally cylindrical shape. Of course, it is also conceivable to provide a lug of substantially different general shape having for example a symmetrical cross section of revolution, in particular polygonal.

L'enveloppe 20, de forme générale tubulaire, comporte une portion annulaire 50 s'étendant axialement vers le bas à partir d'une extrémité inférieure de la tête 24. La dimension radiale de la portion annulaire 50 est réduite par rapport à celle de la tête 24 de manière à ménager un épaulement 52 radial annulaire formant butée pour le montage du manchon 22 extérieur. Une rainure 54 longitudinale s'étend axialement à partir de l'extrémité inférieure de la portion annulaire 50 de l'enveloppe 20 jusqu'au niveau de l'épaulement 52 radial. Dans la position de stockage du stick S, la rainure 54 est alignée dans le sens circonférentiel avec l'extension 34b de la rainure 34 du fourreau 18. La rainure 54 est traversante de manière à permettre le passage de l'ergot 48 de la cupule de support 16 à travers elle.The casing 20, of generally tubular shape, comprises an annular portion 50 extending axially downwards from a lower end of the head 24. The radial dimension of the annular portion 50 is reduced relative to that of the head 24 so as to provide an annular radial shoulder 52 forming a stop for mounting the sleeve 22 outside. A longitudinal groove 54 extends axially from the lower end of the annular portion 50 of the casing 20 to the level of the radial shoulder 52. In the storage position of the stick S, the groove 54 is aligned in the circumferential direction with the extension 34b of the groove 34 of the sleeve 18. The groove 54 is through so as to allow the passage of the lug 48 of the cup of support 16 through it.

La portion annulaire 50 de l'enveloppe 20 comporte également, à son extrémité inférieure, un bourrelet 56 radial s'étendant vers l'extérieur et adapté de manière à pouvoir interférer diamétralement avec le manchon 22 extérieur pour sa retenue sur la portion annulaire 50. Le bourrelet 56 forme un moyen de retenue axiale du manchon extérieur 22 sur l'enveloppe 20. En d'autres termes, le bourrelet 56 forme un moyen d'encliquetage du manchon extérieur 22 sur l'enveloppe 20.The annular portion 50 of the casing 20 also comprises, at its lower end, a radially extending bead 56 which is adapted to be able to interfere diametrically with the outer sleeve 22 for its retention on the annular portion 50. The bead 56 forms an axial retaining means of the outer sleeve 22 on the envelope 20. In other words, the bead 56 forms a latching means of the outer sleeve 22 on the envelope 20.

La portion annulaire 50 de l'enveloppe 20 comporte encore, axialement au voisinage de l'épaulement 52, une encoche 58 de forme générale en C orientée axialement vers le bas et délimitant une languette 60 axiale flexible dans le sens radial. La languette 60 comporte, sur sa surface intérieure, un ergot 62 radial s'étendant vers l'intérieur et présentant une dimension adaptée pour pénétrer à l'intérieur de la rainure 36 du fourreau 18 sans interférer diamétralement avec la surface extérieure de la cupule de support 16. L'ergot 62 est diamétralement opposé à la rainure 54.The annular portion 50 of the casing 20 further includes, axially in the vicinity of the shoulder 52, a notch 58 of generally C-shaped axially downwardly and delimiting an axially flexible tongue 30 in the radial direction. The tongue 60 has, on its inner surface, a radially inwardly extending lug 62 having a dimension adapted to penetrate inside the groove 36 of the sleeve 18 without interfering diametrically with the outer surface of the cup. support 16. The lug 62 is diametrically opposed to the groove 54.

Comme cela sera décrit plus en détail par la suite, l'ergot 62 coopère avec la rainure 36 pour permettre notamment un guidage ou déplacement conjoint du fourreau 18 et de la cupule de support 16 relativement à ladite enveloppe. L'ergot 62 présente ici une forme générale cylindrique. Bien entendu, il est également envisageable de prévoir un ergot de forme générale sensiblement différente ayant par exemple une section transversale symétrique de révolution, notamment polygonale.As will be described in more detail later, the lug 62 cooperates with the groove 36 to allow in particular a guide or joint movement of the sleeve 18 and the support cup 16 relative to said envelope. The lug 62 here has a shape general cylindrical. Of course, it is also conceivable to provide a lug of substantially different general shape having for example a symmetrical cross section of revolution, in particular polygonal.

La languette 60 portant l'ergot 62 facilite le montage par coulissement du sous-ensemble formé par la cupule de support 16 et le fourreau 18 à l'intérieur de l'enveloppe 20. En effet, lors de cette opération, la languette 60 permet d'obtenir un déplacement radial vers l'extérieur de l'ergot 62 jusqu'à ce qu'il vienne se loger dans la rainure 36.The tongue 60 bearing the lug 62 facilitates the assembly by sliding of the subassembly formed by the support cup 16 and the sleeve 18 inside the envelope 20. In fact, during this operation, the tongue 60 allows to obtain a radial displacement towards the outside of the lug 62 until it becomes lodged in the groove 36.

La dimension axiale de l'enveloppe 20 est légèrement supérieure à celle du fourreau 18 de guidage de sorte que le bord supérieur 28 dudit fourreau soit axialement légèrement en retrait par rapport à une surface supérieure 64 de la tête 24 de l'enveloppe 20 dans la position de stockage du stick S illustrée aux figures 1, 5 et 6. Dans cette position, le fourreau 18 est entièrement situé à l'intérieur de l'enveloppe 20. Le fourreau 18 est radialement en contact contre l'alésage de l'enveloppe 20 délimité par la tête 24 et la portion annulaire 50. La surface supérieure 64 de l'enveloppe 20 est biseautée selon une inclinaison identique à celle de la surface 30 du stick S.The axial dimension of the casing 20 is slightly greater than that of the guiding sheath 18 so that the upper edge 28 of said sheath is axially slightly recessed with respect to an upper surface 64 of the head 24 of the casing 20 in the casing. storage position of the stick S illustrated in figures 1 , 5 and 6 . In this position, the sleeve 18 is entirely located inside the envelope 20. The sleeve 18 is radially in contact against the bore of the envelope 20 delimited by the head 24 and the annular portion 50. The upper surface 64 of the envelope 20 is tapered at an inclination identical to that of the surface 30 of the stick S.

Le manchon 22, de forme générale tubulaire, comporte un corps 67 annulaire, d'axe X-X', comprenant une rainure 68 pratiquée sur son alésage afin qu'une rotation du manchon autour de l'axe X-X' puisse s'accompagner d'un déplacement axial conjoint vers le haut du fourreau 18 et de la cupule de support 16 relativement à l'enveloppe 20, puis d'un déplacement axial vers le haut de ladite cupule relativement au fourreau et à l'enveloppe. Dans ce but, l'ergot 48 de la cupule de support 16 présente une dimension radiale suffisante pour pénétrer dans la rainure 68, après traversée des rainures 34 et 54 du fourreau 18 et de l'enveloppe 20.The sleeve 22, of generally tubular shape, comprises an annular body 67, of axis X-X ', comprising a groove 68 formed on its bore so that a rotation of the sleeve about the axis XX' may be accompanied by a joint axial upward movement of the sheath 18 and the support cup 16 relative to the casing 20, and then an axial upward movement of said cup relative to the sheath and the casing. For this purpose, the lug 48 of the support cup 16 has a radial dimension sufficient to penetrate the groove 68, after passing through the grooves 34 and 54 of the sheath 18 and the casing 20.

Le corps 67 du manchon 22 est fermé à une extrémité axiale inférieure par un fond 70 radial. A proximité immédiate dudit fond est prévue une encoche 72 annulaire ménagée dans l'épaisseur du manchon 22 de manière non traversante de manière à délimiter une surface d'appui 74 radiale prévue pour coopérer avec le bourrelet 56 de l'enveloppe 20 de manière à pouvoir obtenir l'encliquetage du manchon 22 sur ladite enveloppe. Le manchon 22 est radialement en contact contre la portion annulaire 50 de l'enveloppe 20 et est maintenu axialement entre l'épaulement 52 radial et le bourrelet 56. Le manchon 22 est mobile en rotation sur l'enveloppe autour de l'axe X-X'.The body 67 of the sleeve 22 is closed at a lower axial end by a radial bottom 70. In the immediate vicinity of said bottom is provided an annular notch 72 formed in the thickness of the sleeve 22 in a non-through manner so as to delimit a radial bearing surface 74 provided to cooperate with the bead 56 of the casing 20 so as to be able to snap the sleeve 22 onto said casing. The sleeve 22 is radially in contact against the annular portion 50 of the casing 20 and is held axially between the radial shoulder 52 and the bead 56. The sleeve 22 is rotatable on the casing about the X axis. X '.

La rainure 68 comporte une portion circonférentielle 68a s'étendant axialement vers le haut à partir du bord supérieur de l'encoche 72 et s'étendant dans le sens circonférentiel sur une plage angulaire limitée qui est ici inférieure à 180°. La rainure 68 comporte également une portion hélicoïdale 68b prolongeant une extrémité circonférentielle de la portion 68a et s'étendant vers le haut jusqu'à déboucher au niveau d'une surface supérieure 76 radiale du manchon 22 venant en appui contre l'épaulement 52 de l'enveloppe 20.The groove 68 has a circumferential portion 68a extending axially upwards from the upper edge of the notch 72 and extending in the circumferential direction over a limited angular range which is here less than 180 °. The groove 68 also includes a helical portion 68b extending a circumferential end of the portion 68a and extending upwardly to open at a radial upper surface 76 of the sleeve 22 bearing against the shoulder 52 of the envelope 20.

L'étui de protection 14 comporte un organe de manoeuvre ou d'actionnement 80 configuré pour permettre l'entraînement en rotation du manchon 22, un capot 82 entourant le manchon 22 et l'enveloppe 20, et un volet d'obturation 84 monté sur ledit capot de manière à fermer une chambre à l'intérieur de laquelle est entièrement logé l'ensemble de distribution 12. L'organe d'actionnement 80 est monté à l'extrémité inférieure du capot 82 et le volet d'obturation 82 est monté à l'extrémité supérieure.The protective case 14 comprises an operating or actuating member 80 configured to allow the rotation of the sleeve 22, a cover 82 surrounding the sleeve 22 and the casing 20, and a shutter 84 mounted on said hood so as to close a chamber inside which is entirely housed the distribution assembly 12. The actuating member 80 is mounted at the lower end of the cover 82 and the shutter flap 82 is mounted at the upper end.

L'organe d'actionnement 80, centré sur l'axe X-X', comporte un corps 86 annulaire fermé à une extrémité axiale inférieure par un fond 88 radial. L'organe de manoeuvre 80 forme une embase à l'intérieur de laquelle sont montés en partie le manchon 22, l'enveloppe 20 et le fourreau 18. En d'autres termes, l'organe de manoeuvre entoure radialement une partie inférieure du manchon 22. La retenue axiale de l'organe d'actionnement 80 sur le manchon 22 peut être réalisée par tout moyen approprié, par exemple par encliquetage en prévoyant un ou des crochets radiaux sur l'alésage du corps 86 aptes à coopérer avec une gorge ménagée sur la surface extérieure du manchon 22, ou inversement.The actuating member 80, centered on the X-X 'axis, comprises an annular body 86 closed at a lower axial end by a radial bottom 88. The operating member 80 forms a base inside which the sleeve 22, the casing 20 and the sleeve 18 are partly mounted. In other words, the actuator radially surrounds a lower portion of the sleeve. 22. The axial retention of the actuating member 80 on the sleeve 22 can be achieved by any appropriate means, for example by snap-fitting by providing one or radial hooks on the bore of the body 86 adapted to cooperate with a groove on the outer surface of the sleeve 22, or vice versa.

Pour permettre l'entraînement du manchon 22 lors d'une rotation de l'organe de manoeuvre 80 autour de l'axe X-X', des plots 90 sont prévus sur la surface supérieure du fond 88 et se raccordent sur le corps 86. Les plots 90 coopèrent par complémentarité de forme avec des logements 92 correspondants ménagés sur la surface inférieure du fond 70 du manchon 22. Les plots 90 sont ici au nombre de huit et répartis de manière régulière sur la circonférence du fond 88. Les plots 90 présentent ici une forme générale parallélépipédique. Bien entendu, il est également envisageable de prévoir un nombre ainsi qu'une autre répartition différents de plots sur le fond 88. Il est encore possible de prévoir des plots de forme différente pour coopérer par conjugaison de forme avec les logements correspondants du manchon 22. Dans une variante de réalisation, il pourrait encore être possible de prévoir un fond 88 articulé à rotation pour permettre l'introduction de l'ensemble de distribution 12 à l'intérieur de la chambre délimitée par l'organe d'actionnement 80 et le capot 82.To allow driving of the sleeve 22 during a rotation of the actuating member 80 about the axis X-X ', pads 90 are provided on the upper surface of the bottom 88 and are connected to the body 86. The pads 90 cooperate in complementary form with corresponding housing 92 formed on the lower surface of the bottom 70 of the sleeve 22. The studs 90 are here eight in number and evenly distributed on the circumference of the bottom 88. The pads 90 present here a parallelepipedic general shape. Of course, it is also conceivable to provide a number and another different distribution of pads on the bottom 88. It is still possible to provide pads of different shape to cooperate by form conjugation with the corresponding housing of the sleeve 22. In an alternative embodiment, it could still be possible to provide a rotatably articulated bottom 88 to allow the introduction of the dispensing assembly 12 inside the chamber delimited by the actuating member 80 and the hood 82.

Le capot 82 comporte un corps 94 tubulaire, d'axe X-X', en contact axial contre le bord supérieur de l'organe d'actionnement 80 et prolongé, à une extrémité axiale supérieure, radialement vers l'intérieur par une paroi 96 biseautée annulaire supérieure en concordance de forme avec la surface supérieure 64 de l'enveloppe 20. La surface supérieure 64 vient en appui contre la surface inférieure de la paroi 96. Ladite paroi délimite un orifice de sortie 98 pour le stick S. Le corps 94 entoure radialement la partie du manchon 22 laissée libre par l'organe d'actionnement 80, et la tête 24 de l'enveloppe 20. Dans la position de stockage du stick S illustrée aux figures 1, 5 et 6, l'ensemble de distribution 12 est donc entièrement logé à l'intérieur de l'organe de manoeuvre 80 et du capot 82. La retenue axiale du capot 82 sur l'enveloppe 20 peut être réalisée par tout moyen approprié, par exemple par encliquetage en prévoyant un ou des crochets radiaux sur l'alésage du corps 94 aptes à coopérer avec une gorge ménagée sur la surface extérieure de la tête 24, ou inversement. Il est également possible de prévoir un capot 82 encliqueté sur l'organe de manoeuvre 80 tout en permettant une rotation relative de ces deux éléments, par exemple par coopération d'un ou plusieurs ergots avec une gorge circulaire.The cover 82 comprises a tubular body 94, of axis X-X ', in axial contact with the upper edge of the actuating member 80 and extended, at an upper axial end, radially inwardly by a wall 96 upper annular bevel conformally shaped with the upper surface 64 of the casing 20. The upper surface 64 abuts against the lower surface of the wall 96. Said wall defines an outlet port 98 for the stick S. The body 94 radially surrounds the portion of the sleeve 22 left free by the actuating member 80, and the head 24 of the envelope 20. In the storage position of the stick S illustrated in FIGS. figures 1 , 5 and 6 , the distribution assembly 12 is therefore entirely housed inside the operating member 80 and the cover 82. The axial retention of the cover 82 on the casing 20 can be achieved by any appropriate means, for example by snapping by providing one or radial hooks on the bore of the body 94 adapted to cooperate with a groove on the outer surface of the head 24, or vice versa. It is also possible to provide a cap 82 snapped onto the operating member 80 while allowing relative rotation of these two elements, for example example by cooperation of one or more lugs with a circular groove.

Pour assurer l'articulation du volet d'obturation 84 sur le capot 82, celui-ci comporte deux oreilles 100 prévues sur la surface extérieure du corps 94 au voisinage de la paroi 96 en étant espacées l'une de l'autre pour permettre le passage d'une patte 102 dudit volet. L'articulation du volet d'obturation 84 s'effectue par l'intermédiaire d'un axe rapporté (non représenté) passant à travers les oreilles 100 et la patte 102. L'axe rapporté s'étend transversalement ou perpendiculairement à l'axe X-X'. Le volet d'obturation 84 peut ainsi être mobile entre une position de fermeture de l'orifice de sortie 98 dans laquelle il vient en appui contre la surface supérieure de la paroi 96 et une position d'ouverture, et inversement.To ensure the articulation of the shutter 84 on the cover 82, it has two lugs 100 provided on the outer surface of the body 94 in the vicinity of the wall 96 being spaced from each other to allow the passage of a tab 102 of said flap. The articulation of the shutter 84 is effected by means of an attached shaft (not shown) passing through the lugs 100 and the lug 102. The attached axle extends transversely or perpendicularly to the axis XX '. The shutter 84 can thus be movable between a closed position of the outlet orifice 98 in which it bears against the upper surface of the wall 96 and an open position, and vice versa.

Dans le mode de réalisation illustré, le volet d'obturation 84 est monté à rotation sur le capot 82 par l'intermédiaire d'un axe d'articulation rapporté. En variante, le volet d'obturation 84 et le capot 82 pourraient être réalisés en une seule pièce et l'articulation obtenue via une charnière-film.In the illustrated embodiment, the shutter 84 is rotatably mounted on the cover 82 via a hinge axis reported. Alternatively, the shutter 84 and the cover 82 could be made in one piece and the hinge obtained via a hinge-film.

Dans la position de stockage du stick S illustrée aux figures 1, 5 et 6, le stick S est situé axialement en retrait par rapport aux orifices de sortie 26, 98 et le volet recouvre la paroi 96 du capot 82. L'ensemble de distribution 12 n'est donc pas visible, ni accessible pour l'utilisateur.In the storage position of the stick S illustrated in figures 1 , 5 and 6 , the stick S is located axially recessed relative to the outlet ports 26, 98 and the flap covers the wall 96 of the cover 82. The distribution assembly 12 is not visible or accessible to the user.

Dans cette position, l'ergot 48 de la cupule de support 16 s'étend à travers l'extension 34b de la rainure 34 du fourreau 18 et la rainure 54 de l'enveloppe 20. Il pénètre également dans la rainure 68 du manchon 22 au niveau de la zone de la portion circonférentielle 68a immédiatement adjacente à la portion hélicoïdale 68b. L'ergot 62 de l'enveloppe 20 est quant à lui situé à l'extrémité supérieure de la portion longitudinale 36a de la rainure 36 du fourreau 18.In this position, the lug 48 of the support cup 16 extends through the extension 34b of the groove 34 of the sleeve 18 and the groove 54 of the envelope 20. It also penetrates into the groove 68 of the sleeve 22 at the area of the circumferential portion 68a immediately adjacent to the helical portion 68b. The lug 62 of the casing 20 is located at the upper end of the longitudinal portion 36a of the groove 36 of the sheath 18.

Pour permettre le passage du stick S de la position de stockage vers une position d'utilisation, il convient d'entraîner en rotation l'organe de manoeuvre 80 par rapport au capot 82 autour de l'axe X-X' pour commander la rotation du manchon 22 relativement à l'enveloppe 20.To allow the passage of the stick S from the storage position to a position of use, it is necessary to rotate the operating member 80 relative to the cover 82 about the axis X-X ' for controlling the rotation of the sleeve 22 relative to the envelope 20.

Dans une première étape, cette rotation provoque le déplacement selon l'axe X-X' du sous-ensemble constitué par le fourreau 18 et la cupule de support 16 relativement à l'enveloppe 20 et à l'étui de protection 14. Ce déplacement axial conjoint est rendu possible d'une part par le coulissement de l'ergot 48 de la cupule de support 16 dans la rainure 54 de l'enveloppe 20 et dans la portion hélicoïdale 68b de la rainure 68 du manchon 22, et d'autre part par le coulissement de l'ergot 62 à l'intérieur de la portion longitudinale 36a de la rainure 36 du fourreau 18 jusqu'à être située à l'extrémité inférieure de ladite portion. Durant cette phase de montée conjointe de la cupule de support 16 et du fourreau 18, l'ergot 48 de ladite cupule reste logé dans l'extension 34b de la rainure 34.In a first step, this rotation causes displacement along the axis XX 'of the subassembly constituted by the sleeve 18 and the support cup 16 relative to the envelope 20 and the protective case 14. This joint axial displacement is made possible on the one hand by the sliding of the lug 48 of the support cup 16 in the groove 54 of the casing 20 and in the helical portion 68b of the groove 68 of the sleeve 22, and on the other hand by the sliding of the lug 62 inside the longitudinal portion 36a of the groove 36 of the sleeve 18 to be located at the lower end of said portion. During this phase of joint rise of the support cup 16 and the sheath 18, the lug 48 of said cup remains housed in the extension 34b of the groove 34.

La dimension axiale de la portion longitudinale 36a de la rainure 36 est adaptée en fonction du déplacement axial souhaité du sous-ensemble formé par le fourreau 18 et la cupule de support 16 relativement à l'enveloppe 20 et à l'étui de protection 14. Dans le mode de réalisation illustré, lorsque l'ergot 62 de l'enveloppe 20 est situé à l'extrémité inférieure de la portion longitudinale 36a de la rainure 36, le fourreau 18 et le stick S s'étendent en partie à travers les orifices de sortie 26, 98 et sont en saillie axiale par rapport à la paroi 96 en étant ainsi visibles depuis l'extérieur de l'étui de protection 14. Le volet d'obturation 84 peut être déplacé en position d'ouverture de l'orifice de sortie 98 par la poussée exercée par le fourreau 18 et le stick S lors de leur montée axiale conjointe. Alternativement, l'utilisateur peut déplacer le volet d'obturation 84 avant de commencer l'entraînement en rotation de l'organe d'actionnement 80.The axial dimension of the longitudinal portion 36a of the groove 36 is adapted as a function of the desired axial displacement of the subassembly formed by the sleeve 18 and the support cup 16 relative to the envelope 20 and to the protective case 14. In the illustrated embodiment, when the lug 62 of the casing 20 is located at the lower end of the longitudinal portion 36a of the groove 36, the sheath 18 and the stick S extend partly through the orifices. output 26, 98 and are projecting axially relative to the wall 96 thus being visible from the outside of the protective case 14. The shutter 84 can be moved to the opening position of the orifice output 98 by the thrust exerted by the sleeve 18 and the stick S during their joint axial rise. Alternatively, the user can move the shutter 84 before starting the rotational drive of the actuator 80.

Dans une seconde étape, la rotation du manchon 22 relativement à l'enveloppe 20, autour de l'axe X-X', provoque un court déplacement axial du fourreau 18 et de la cupule de support 16 relativement à l'enveloppe 20 combiné à une légère rotation dudit fourreau relativement à l'enveloppe et à la cupule de support. Ce mouvement combiné de translation et de rotation du fourreau 18 est rendu possible par le coulissement de l'ergot 62 dans l'extension 36b de la rainure 36 du fourreau 18 jusqu'à ce qu'il atteigne l'extrémité inférieure de ladite extension. La rotation du fourreau 18 autour de l'axe X-X' permet d'obtenir le passage de l'ergot 48 de la cupule de support 16 de l'extension 34b à l'extrémité inférieure de la portion longitudinale 34a de la rainure 34 comme illustré sur les figures 7 et 8 représentant une position de sortie intermédiaire du stick S de produit. La longueur de l'extension 36b de la rainure 36 est adaptée en fonction de la rotation devant être réalisée par le fourreau 18 relativement à l'enveloppe 20 de manière que la portion longitudinale 34a de la rainure 34 soit alignée dans le sens circonférentiel avec la rainure 54 dans cette position de sortie intermédiaire. Cette rotation du fourreau 18 autour de l'axe X-X' peut être de l'ordre de 15°.In a second step, the rotation of the sleeve 22 relative to the casing 20, about the axis X-X ', causes a short axial displacement of the sleeve 18 and the support cup 16 relative to the envelope 20 combined with a slight rotation of said sheath relative to the envelope and the support cup. This combined movement of translation and rotation of the sleeve 18 is made possible by the sliding of the lug 62 in the extension 36b of the groove 36 of the sleeve 18 until it reaches the lower end of said extension. The rotation of the sheath 18 around the axis XX 'makes it possible to obtain the passage of the lug 48 of the support cup 16 from the extension 34b to the lower end of the longitudinal portion 34a of the groove 34 as illustrated. on the Figures 7 and 8 representing an intermediate output position of the product stick S. The length of the extension 36b of the groove 36 is adapted according to the rotation to be performed by the sleeve 18 relative to the casing 20 so that the longitudinal portion 34a of the groove 34 is aligned in the circumferential direction with the groove 54 in this intermediate output position. This rotation of the sleeve 18 around the axis XX 'can be of the order of 15 °.

Dans une troisième étape, la rotation du manchon 22 relativement à l'enveloppe 20, autour de l'axe X-X', provoque le coulissement de l'ergot 48 le long de la portion longitudinale 34a de la rainure 34 et de la rainure 54 jusqu'à ce que ledit ergot vienne buter contre l'extrémité supérieure de la portion longitudinale 34a comme illustré sur les figures 9 et 10.In a third step, the rotation of the sleeve 22 relative to the casing 20, about the axis X-X ', causes the sliding of the lug 48 along the longitudinal portion 34a of the groove 34 and the groove 54 until said lug abuts against the upper end of the longitudinal portion 34a as illustrated in FIGS. Figures 9 and 10 .

A partir de la position de sortie intermédiaire du stick S, on obtient ainsi le coulissement axial de la cupule de support 16 relativement au fourreau 18, à l'enveloppe 20 et à l'étui de protection 14 jusqu'à la position de sortie finale ou d'utilisation du stick. La dimension axiale de la portion longitudinale 34a de la rainure 34 est adaptée en fonction de la distance axiale souhaitée entre la surface biseautée 30 supérieure du stick S et le bord supérieur 28 du fourreau 18 dans la position d'utilisation du stick.From the intermediate output position of the stick S, the axial sliding of the support cup 16 is thus obtained relative to the sleeve 18, to the envelope 20 and to the protective case 14 to the final output position. or using the stick. The axial dimension of the longitudinal portion 34a of the groove 34 is adapted as a function of the desired axial distance between the upper bevelled surface of the stick S and the upper edge 28 of the sleeve 18 in the use position of the stick.

Lors de l'entraînement en rotation de l'organe de manoeuvre 80 autour de l'axe X-X', il se produit donc un mouvement séquencé comportant une première phase durant laquelle le fourreau 18 et la cupule de support 16 coulissent conjointement le long de l'axe X-X' relativement à l'enveloppe 20 et à l'étui de protection 14 pour passer de la position de stockage du stick S illustrée aux figures 1, 5 et 6 à la position de sortie intermédiaire illustrée aux figures 2, 7 et 8. Ce déplacement axial simultané est suivi ensuite d'une seconde phase durant laquelle est réalisé le seul déplacement axial de la cupule de support 16 relativement au fourreau 18, à l'enveloppe 20 et à l'étui de protection 14 pour obtenir le passage du stick S dans la position d'utilisation illustrée aux figures 3, 9 et 10. Bien entendu, le passage de cette position d'utilisation vers la position de stockage s'effectue également de manière séquencée lors d'une rotation de l'organe de manoeuvre 80 autour de l'axe X-X' dans le sens opposé à celui ayant permis la distribution dudit stick.During the rotational drive of the operating member 80 about the axis X-X ', there is therefore a sequenced movement comprising a first phase during which the sleeve 18 and the support cup 16 slide together along of the axis XX 'relative to the envelope 20 and the protective case 14 to move from the storage position of the stick S illustrated in FIGS. figures 1 , 5 and 6 to the intermediate exit position illustrated in figures 2 , 7 and 8 . This simultaneous axial displacement is then followed by a second phase during which the only axial displacement of the support cup 16 relative to the sleeve 18, to the envelope 20 and to the protective case 14 is achieved to obtain the passage of the stick. S in the position of use illustrated in figures 3 , 9 and 10 . Of course, the passage from this use position to the storage position is also performed sequentially during a rotation of the operating member 80 about the axis XX 'in the opposite direction to that which allowed the distribution of said stick.

Avantageusement, au niveau de l'extrémité supérieure des bords de la portion longitudinale 34a de la rainure 34 du fourreau 18 et/ou de la rainure 54 de l'enveloppe 20, un cran par exemple réalisé sous forme de grains de riz ou bossages peut être pratiqué de manière à permettre un blocage de la cupule de support 16 dans la position d'utilisation du stick S de sorte que ledit stick n'ait pas tendance à descendre lors d'une application de produit si l'utilisateur lâche l'organe de manoeuvre 80.Advantageously, at the upper end of the edges of the longitudinal portion 34a of the groove 34 of the sleeve 18 and / or the groove 54 of the casing 20, a notch for example made in the form of grains of rice or bosses may be practiced so as to allow blocking of the support cup 16 in the position of use of the stick S so that said stick does not tend to descend during a product application if the user drops the organ maneuvering 80.

Comme illustré sur les figures 3, 9 et 10, la surface biseautée 30 supérieure du stick S est parallèle à la paroi 96 supérieure de l'étui de protection 14 dans la position d'utilisation. Ainsi, l'utilisateur sait comment positionner au préalable le dispositif 10 par rapport à la surface à traiter de manière à obtenir dans la position de sortie du stick l'orientation souhaitée de la surface biseautée 30 supérieure par rapport à ladite surface à traiter. Les plots 90 de l'organe de manoeuvre 80 permettant l'entraînement en rotation du manchon 22 forment à cet égard des moyens d'indexation angulaire du manchon relativement à l'étui de protection 14 pour obtenir le parallélisme entre la surface supérieure 30 biseautée du stick S et la paroi 96 du capot 82 dans la position d'utilisation dudit stick.As illustrated on figures 3 , 9 and 10 the upper bevelled surface of the stick S is parallel to the upper wall 96 of the protective case 14 in the position of use. Thus, the user knows how to position the device 10 in advance with respect to the surface to be treated so as to obtain in the output position of the stick the desired orientation of the upper bevelled surface with respect to said surface to be treated. The pads 90 of the operating member 80 for driving in rotation the sleeve 22 form in this respect means for angular indexing of the sleeve relative to the protective case 14 to obtain the parallelism between the beveled upper surface 30 of the stick S and the wall 96 of the cover 82 in the position of use of said stick.

Dans le mode de réalisation illustré, le volet d'obturation 84 peut être déplacé en position d'ouverture de l'orifice de sortie 98 par la poussée exercée par le fourreau 18 et le stick S lors de leur montée axiale conjointe, ou alternativement par l'utilisateur avant de commencer l'entraînement en rotation de l'organe d'actionnement 80.In the illustrated embodiment, the shutter 84 can be moved to the open position of the outlet orifice 98 by the thrust exerted by the sleeve 18 and the stick S during their ascent axial joint, or alternatively by the user before starting the rotational drive of the actuating member 80.

Dans une variante de réalisation, il pourrait également être possible de commander l'ouverture du volet d'obturation 84 lors de l'entraînement en rotation de l'organe de manoeuvre 80 visant à permettre le passage du stick S de la position de stockage vers la position d'utilisation.In an alternative embodiment, it could also be possible to control the opening of the shutter 84 during the rotational drive of the operating member 80 to allow the passage of the stick S from the storage position to the position of use.

Dans ce but, la portion circonférentielle 68a de la rainure 68 est utilisée pour permettre le déplacement du volet d'obturation 84 de la position de fermeture de l'orifice de sortie 98 à la position d'ouverture grâce au coulissement de l'ergot 48 de la cupule de support 16 à l'intérieur de celle-ci. Lors de cette étape, le déplacement axial conjoint du fourreau 18 et de la cupule de support 16 n'a pas encore débuté. Dans la position de stockage du stick S, il convient de prévoir que l'ergot 48 de la cupule de support 16 pénètre dans la portion circonférentielle 68a de la rainure 68 dans une zone opposée à la zone immédiatement adjacente à la portion hélicoïdale 68b, et que la portion circonférentielle 68a s'étende dans le sens circonférentiel sur une plage angulaire suffisante pour permettre, lors de la rotation de l'organe de manoeuvre 80 autour de l'axe X-X', le dégagement complet de l'orifice de sortie 98 par le volet d'obturation 84 avant que l'ergot 48 n'atteigne la zone de la portion circonférentielle 68a immédiatement adjacente à la portion hélicoïdale 68b permettant la montée du fourreau 18 et de la cupule de support 16. A titre indicatif, la portion circonférentielle 68a de la rainure 68 peut s'étendre sur une plage angulaire allant de 5 à 355°, et notamment de 100 à 200°, et de préférence de l'ordre de 162°.For this purpose, the circumferential portion 68a of the groove 68 is used to allow the closure shutter 84 to move from the closed position of the outlet orifice 98 to the open position by sliding the lug 48. of the support cup 16 inside thereof. During this step, the joint axial displacement of the sleeve 18 and the support cup 16 has not yet begun. In the storage position of the stick S, provision should be made for the lug 48 of the support cup 16 to enter the circumferential portion 68a of the groove 68 in an area opposite to the zone immediately adjacent to the helicoidal portion 68b, and that the circumferential portion 68a extends in the circumferential direction over a sufficient angular range to allow, during the rotation of the actuating member 80 about the axis X-X ', the complete clearance of the outlet orifice 98 by the shutter 84 before the lug 48 reaches the area of the circumferential portion 68a immediately adjacent to the helical portion 68b allowing the rise of the sleeve 18 and the support cup 16. As an indication, the circumferential portion 68a of the groove 68 may extend over an angular range from 5 to 355 °, and in particular from 100 to 200 °, and preferably of the order of 162 °.

Dans l'ensemble de la demande de brevet, par « comprendre » ou « comporter », il convient d'entendre « comprendre au moins » ou « comporter au moins ».Throughout the patent application, by "understand" or "include", it is appropriate to include "understand at least" or "include at least".
