Description

La présente invention concerne un distributeur de produit, du type comportant un corps à l'intérieur duquel est mobile un poussoir, des moyens d'entraínement débrayables pour entraíner en déplacement axial ledit poussoir afin de distribuer du produit et des moyens de rappel pour ramener le poussoir dans une position initiale lors du débrayage desdits moyens d'entraínement.The present invention relates to a product dispenser, of the type comprising a body inside which is movable a pusher, disengageable drive means to cause axial movement of said pusher in order to distribute product and return means for returning the pusher to an initial position when disengagement of said drive means.

Un tel distributeur est décrit dans la demande internationale WO 98/09548.Such a dispenser is described in international application WO 98/09548.

L'invention a pour but de perfectionner un distributeur de ce type.The invention aims to improve a dispenser of this type.

On connaít par le brevet US 2 526 089 un applicateur de rouge à lèvres comportant un tube dans lequel est introduit un support coulissant rappelé vers le fond du tube par un ressort travaillant en traction. Le support est pourvu d'un ergot s'engageant dans une fente axiale du tube. Le support peut être déplacé vers le haut grâce à un capuchon s'engageant sur le tube et apte à pousser l'ergot vers le haut.We know from US Patent 2,526,089 a lipstick applicator comprising a tube into which is inserted a sliding support biased towards the bottom of the tube by a spring working in traction. The support is provided with a lug engaging in an axial slot of the tube. The support can be moved upwards by means of a cap engaging the tube and able to push the lug upwards.

Le distributeur selon l'invention se caractérise par le fait que les moyens de rappel comportent un organe élastique travaillant en traction.The dispenser according to the invention is characterized in that the means for recall include an elastic member working in traction.

Avantageusement, cet organe élastique est logé au moins partiellement dans le poussoir.Advantageously, this elastic member is housed at least partially in the pusher.

Grâce à l'invention, l'encombrement axial du distributeur peut être réduit par rapport à celui du distributeur décrit dans la demande internationale WO 98/09548, lequel utilise un ressort hélicoïdal travaillant en compression.Thanks to the invention, the axial size of the dispenser can be reduced by compared to that of the distributor described in international application WO 98/09548, which uses a helical spring working in compression.

Avantageusement, l'organe élastique est agencé de manière à amortir le mouvement de retour du poussoir dans sa position initiale.Advantageously, the elastic member is arranged so as to dampen the movement of the pusher back to its initial position.

Ainsi, la structure du distributeur peut être simplifiée par rapport à celle décrite dans la demande WO 98/09548.Thus, the structure of the dispenser can be simplified compared to that described in application WO 98/09548.

De préférence, l'organe élastique est fixé à une extrémité au fond du corps du distributeur et à l'autre extrémité au poussoir.Preferably, the elastic member is fixed at one end to the bottom of the body dispenser and at the other end to the pusher.

Dans une réalisation particulière, le poussoir comporte une tige filetée ou crantée prolongée à une extrémité par une partie cylindrique de plus grand diamètre que la tige, l'organe élastique étant logé en majorité dans ladite partie cylindrique lorsque le poussoir est dans sa position initiale.In a particular embodiment, the pusher comprises a threaded rod or notched extended at one end by a cylindrical part of larger diameter than the rod, the elastic member being housed mainly in said cylindrical part when the pusher is in its initial position.

Dans une autre réalisation particulière, le poussoir comporte une tige creuse filetée ou crantée dans laquelle l'organe élastique est logé en majorité lorsque le poussoir est dans sa position initiale.In another particular embodiment, the pusher comprises a hollow rod threaded or notched in which the elastic member is mainly housed when the pusher is in its original position.

Dans une réalisation particulière, le poussoir comporte au moins une partie ayant une section non cylindrique de révolution permettant de l'immobiliser en rotation et de le guider dans une partie du corps du distributeur.In a particular embodiment, the pusher comprises at least one part having a non-cylindrical section of revolution making it possible to immobilize it in rotation and guide it in a part of the distributor body.

Dans une réalisation particulière, le corps du distributeur comporte une première et une deuxième parties pouvant tourner l'une par rapport à l'autre. Le poussoir présente un filetage et il est monté avec une possibilité de coulissement dans la première partie du corps du distributeur sans possibilité de rotation relativement à cette partie. Le distributeur comprend des moyens d'entraínement solidaires de la deuxième partie du corps du distributeur, ces moyens d'entraínement comportant au moins un organe d'entraínement mobile entre d'une part une position d'entraínement dans laquelle il vient en prise sur le filetage du poussoir, de telle sorte qu'une rotation relative des deux parties du corps du distributeur provoque un déplacement axial du poussoir, et d'autre part une position débrayée dans laquelle il cesse d'être en prise sur le filetage du poussoir et permet le retour de ce dernier dans sa position initiale sous l'action de rappel de l'organe élastique.In a particular embodiment, the distributor body includes a first and second parts that can rotate relative to each other. The pusher has a thread and is mounted with a possibility of sliding in the first part of the distributor body without the possibility of rotation relative to this part. The dispenser includes drive means integral with the second part of the body of the distributor, these drive means comprising at least one drive member mobile enters on the one hand a training position in which it comes into taken on the thread of the plunger, so that a relative rotation of the two parts of the distributor body causes an axial displacement of the pusher, and on the other hand a disengaged position in which it ceases to be engaged on the thread of the pusher and allows the return of the latter to its initial position under the action of recall of the organ elastic.

Avantageusement, les deux parties du corps du distributeur sont conformées pour s'emboíter l'une dans l'autre, l'organe d'entraínement étant agencé de telle sorte que l'insertion de l'une des parties dans l'autre amène l'organe d'entraínement de sa position débrayée vers sa position d'entraínement et inversement au moment de la séparation desdites parties.Advantageously, the two parts of the distributor body are shaped to fit into each other, the drive member being arranged so that the insertion of one of the parts into the other brings the drive member from its position disengaged to its drive position and vice versa at the time of separation of said parties.

Avantageusement, l'organe d'entraínement est constitué par au moins une patte élastiquement déformable, conformée pour présenter lorsqu'elle est en prise sur le poussoir une certaine élasticité dans le sens axial, cette élasticité permettant au poussoir d'une part de revenir légèrement vers sa position initiale en cas de poussée exercée par l'utilisateur sur le poussoir lors de l'application du produit et d'autre part de laisser échapper le poussoir si cette poussée excède une force prédéterminée.Advantageously, the drive member is constituted by at least one elastically deformable tab, shaped to present when it is engaged on the pusher a certain elasticity in the axial direction, this elasticity allowing the pusher on the one hand to return slightly to its initial position in the event of a push exerted by the user on the pusher when applying the product and secondly to leave escape the pusher if this thrust exceeds a predetermined force.

Avantageusement, la deuxième partie du corps du distributeur comporte un élément coulissant tel qu'un piston ou une cupule. Cet élément coulissant est monté à coulissement dans un passage axial en étant relié de manière amovible au poussoir par des moyens de liaison permettant de séparer l'élément coulissant et le poussoir lorsque les première et deuxième parties du corps du distributeur sont séparées.Advantageously, the second part of the body of the dispenser comprises a sliding element such as a piston or a cup. This sliding element is mounted at sliding in an axial passage while being removably connected to the pusher by connecting means making it possible to separate the sliding element and the pusher when the first and second parts of the distributor body are separated.

Dans une réalisation particulière, les moyens de liaison précités comportent d'une part une mâchoire formée sur l'un du poussoir et de l'élément coulissant et d'autre part une tête formée sur l'autre du poussoir et de l'élément coulissant, ladite mâchoire étant conformée pour enserrer ladite tête lorsque l'élément coulissant est engagé au-delà d'une course prédéterminée à l'intérieur du passage axial précité.In a particular embodiment, the aforementioned connecting means comprise on the one hand a jaw formed on one of the pusher and of the sliding element and on the other share a head formed on the other of the pusher and the sliding element, said jaw being shaped to grip said head when the sliding element is engaged beyond a predetermined stroke inside the aforementioned axial passage.

Avantageusement, l'organe élastique est constitué par un ressort hélicoïdal.Advantageously, the elastic member is constituted by a helical spring.

L'invention a également pour objet un double distributeur caractérisé par le fait qu'il comporte deux distributeurs tels que définis plus haut, disposés en opposition.The invention also relates to a double distributor characterized by the the fact that it has two distributors as defined above, arranged in opposition.

Ce double distributeur peut être d'un encombrement axial compatible avec son utilisation comme accessoire de maquillage, notamment grâce au fait qu'à chaque poussoir est associé un organe élastique travaillant en traction, ce qui permet de gagner en compacité.This double distributor can be axially compatible with its use as a makeup accessory, in particular thanks to the fact that each time pusher is associated with an elastic member working in traction, which makes it possible to gain in compactness.

La première partie 3 est fermée à une extrémité par un bouchon 5 pourvu d'un évent 6 et comporte une nervure annulaire intérieure 7 dont le rôle sera précisé dans la suite.The first part 3 is closed at one end by a plug 5 provided of a vent 6 and has an inner annular rib 7 whose role will be specified in the following.

La deuxième partie 4 est traversée axialement par un passage 8 définissant un logement pour une réserve de produit P se présentant sous la forme d'un bâtonnet par exemple.The second part 4 is crossed axially by a passage 8 defining a housing for a reserve of product P in the form of a stick by example.

Le passage 8 est prolongé du côté de la première partie 3 du corps 2 du distributeur par une embouchure conique 10 dont la fonction sera précisée plus loin.The passage 8 is extended on the side of the first part 3 of the body 2 of the dispenser by a conical mouthpiece 10 whose function will be specified below.

La deuxième partie 4 du corps 2 est insérée dans la première partie 3 et comporte un épaulement extérieur 12 contre lequel l'extrémité avant de la première partie 3 vient buter, comme représenté sur les figures 1 et 2.The second part 4 of the body 2 is inserted into the first part 3 and has an outer shoulder 12 against which the front end of the first part 3 abuts, as shown in FIGS. 1 and 2.

La portion arrière 9 de la deuxième partie 4, engagée à l'intérieur de la première partie 3, est cylindrique de révolution autour de l'axe X et pourvue de deux fentes diamétralement opposées 14, que l'on peut voir sur la figure 5 notamment, dont le rôle sera précisé dans la suite.The rear portion 9 of the second part 4, engaged inside the first part 3, is cylindrical of revolution around the X axis and provided with two slots diametrically opposed 14, which can be seen in Figure 5 in particular, whose role will be specified below.

Le distributeur 1 comporte également un poussoir 15 comprenant une tige filetée 16.The distributor 1 also includes a pusher 15 comprising a rod threaded 16.

Le poussoir 15 est muni à son extrémité arrière d'une partie cylindrique 17 de plus grand diamètre que la tige 16 et à son extrémité avant d'une partie d'accrochage constituée par une tête 18 se raccordant à la tige 16 en ménageant une gorge annulaire 20.The pusher 15 is provided at its rear end with a cylindrical part 17 larger in diameter than rod 16 and at its front end with a hooking portion constituted by a head 18 connecting to the rod 16 by providing an annular groove 20.

Le poussoir 15 est monté à coulissement dans la première partie 3 du corps 2 sans possibilité de rotation par rapport à celle-ci grâce au fait que d'une part la première partie 3 comporte sur sa surface intérieure s'étendant entre le bouchon 5 et la nervure annulaire 7 au moins deux rainures longitudinales 22 diamétralement opposées et que d'autre part la partie cylindrique 17 comporte deux nervures 23 conformées pour coulisser dans les rainures 22 précitées. On peut aussi, dans une variante non représentée, empêcher le poussoir de tourner dans la première partie 3 grâce à l'utilisation d'un poussoir dont la section présente toute forme de section non cylindrique de révolution, par exemple carrée ou ovale.The pusher 15 is slidably mounted in the first part 3 of the body 2 without the possibility of rotation with respect to the latter thanks to the fact that on the one hand the first part 3 has on its inner surface extending between the plug 5 and the rib annular 7 at least two diametrically opposite longitudinal grooves 22 and that on the other hand the cylindrical part 17 has two ribs 23 shaped to slide in the above-mentioned grooves 22. It is also possible, in a variant not shown, prevent the pusher from turning in the first part 3 by using a pusher whose section has any shape of non-cylindrical section of revolution, for example square or oval.

Un organe élastique constitué dans l'exemple décrit par un ressort hélicoïdal 26 est prévu pour solliciter le poussoir 15 en déplacement vers sa position initiale représentée sur la figure 1.An elastic member constituted in the example described by a helical spring 26 is provided to urge the pusher 15 moving towards its initial position shown in figure 1.

Ce ressort 26 travaille en traction. Il est fixé à son extrémité arrière sur la face intérieure 28 du bouchon 5 et à son extrémité avant dans le fond 29 de la partie cylindrique 17 du poussoir 15.This spring 26 works in traction. It is fixed at its rear end on the inner face 28 of plug 5 and at its front end in the bottom 29 of the cylindrical part 17 of pusher 15.

Au repos, les spires du ressort 26 peuvent ne pas être complètement jointives et la longueur du ressort 26 légèrement supérieure à celle de la partie cylindrique 17, de telle sorte que le ressort 26 se trouve non entièrement logé dans cette dernière lorsque le poussoir 15 est dans sa position initiale. Il en résulte d'une part une longueur totale relativement faible pour le distributeur et d'autre part un amortissement du mouvement de retour du poussoir par le ressort 26.At rest, the turns of spring 26 may not be completely contiguous and the length of the spring 26 slightly greater than that of the cylindrical part 17, so that the spring 26 is not entirely housed therein when the pusher 15 is in its initial position. This results on the one hand in a total length relatively low for the distributor and on the other hand a depreciation of the return movement of the pusher by the spring 26.

Le distributeur 1 comporte un organe d'entraínement 30 permettant de transformer une rotation relative des première et deuxième parties du corps 2 en un déplacement axial du poussoir 15.The dispenser 1 includes a drive member 30 for transforming a relative rotation of the first and second parts of the body 2 in one displacement axial of pusher 15.

Cet organe d'entraínement 30 est représenté isolément sur la figure 5 et comporte dans l'exemple décrit deux pattes élastiquement déformables 31, diamétralement opposées, raccordées par une base annulaire 32 épaulée extérieurement de manière à s'emboíter dans l'extrémité arrière de la deuxième partie 4, comme représenté sur la figure 6. En variante, l'organe d'entraínement 30 ne pourrait comporter qu'une seule patte 31 et la deuxième partie une seule fente correspondante 14.This drive member 30 is shown in isolation in Figure 5 and comprises in the example described two elastically deformable legs 31, diametrically opposite, connected by an annular base 32 externally shouldered to fit into the rear end of the second part 4, as shown in the Figure 6. Alternatively, the drive member 30 could include only one tab 31 and the second part a single corresponding slot 14.

Chaque patte 31 comporte une première portion 33 solidaire à une extrémité de la base annulaire 32 et s'éloignant de cette dernière en s'écartant de l'axe X. Cette première portion 31 est prolongée par une deuxième portion 34 formant un coude 35 avec la première et s'éloignant de celle-ci en se rapprochant de l'axe X.Each tab 31 has a first portion 33 secured to one end of the annular base 32 and moving away from the latter away from the axis X. This first portion 31 is extended by a second portion 34 forming a bend 35 with the first and moving away from it while approaching the X axis.

Les coudes 35 des pattes 31 s'étendent hors des fentes 14 de la deuxième partie 4 lorsque l'organe d'entraínement 30 est en place mais la première partie 3 absente, comme on peut le voir sur la figure 6.The elbows 35 of the legs 31 extend out of the slots 14 of the second part 4 when the drive member 30 is in place but the first part 3 absent, as can be seen in Figure 6.

L'écartement entre les extrémités libres des pattes 31 est alors supérieur au diamètre de la tige 16.The spacing between the free ends of the legs 31 is then greater than rod diameter 16.

La nervure annulaire 7 permet de maintenir la base annulaire 32 en appui contre l'extrémité arrière de la deuxième partie 4 dans la position d'utilisation de la figure 2.The annular rib 7 keeps the annular base 32 in abutment against the rear end of the second part 4 in the position of use of the figure 2.

Un élément coulissant 40 est logé à l'intérieur du passage 8 de la deuxième partie 4.A sliding element 40 is housed inside the passage 8 of the second part 4.

Cet élément coulissant 40 présente du côté avant une cupule 41 pour supporter le bâtonnet de produit P et comporte du côté arrière des mâchoires 42 dont les extrémités libres 43 sont écartées au repos d'une distance supérieure au plus grand diamètre de la tête 18. En variante, les mâchoires 42 peuvent être réalisées d'un seul tenant avec le poussoir et la tête 59' réalisée d'un seul tenant avec l'élément coulissant comme illustré sur la figure 10.This sliding element 40 has on the front side a cup 41 for supporting the product stick P and has jaws 42 on the rear side, the free ends 43 are spaced apart at rest by a distance greater than the largest diameter of the head 18. As a variant, the jaws 42 can be made in one piece with the pusher and the head 59 'made in one piece with the sliding element as illustrated in figure 10.

Lorsque la deuxième partie 4 est insérée dans la première partie 3, la tête 18 peut pénétrer entre les mâchoires 42 situées dans l'embouchure conique 10 comme illustré sur la figure 4.When the second part 4 is inserted in the first part 3, the head 18 can penetrate between the jaws 42 located in the conical mouth 10 as illustrated in figure 4.

Au moment où les première et deuxième parties du corps 2 du distributeur sont insérées l'une dans l'autre, le poussoir 15 est maintenu dans sa position initiale du fait de la présence du ressort 26.When the first and second parts of the body 2 of the distributor are inserted one inside the other, the pusher 15 is maintained in its initial position of the made of the presence of the spring 26.

Au cours de cette insertion, les pattes 31 de l'organe d'entraínement 30 sont repoussées vers l'intérieur et viennent en prise par leur extrémité libre sur la tige 16.During this insertion, the legs 31 of the drive member 30 are pushed inwards and engage by their free end on the rod 16.

La longueur du bâtonnet de produit P est choisie de telle sorte que lorsque le poussoir 15 est dans sa position initiale, son extrémité libre se situe légèrement en retrait du nez de la deuxième partie 4, comme on peut le voir sur la figure 1.The length of the product stick P is chosen so that when the pusher 15 is in its initial position, its free end is slightly behind of the nose of the second part 4, as can be seen in Figure 1.

Lorsque la deuxième partie 4 est entraínée en rotation par rapport à la première partie 3 dans un sens déterminé, l'organe d'entraínement 30 provoque l'avancement du poussoir 15 et l'élément coulissant 40 se rapproche de la sortie.When the second part 4 is rotated relative to the first part 3 in a determined direction, the drive member 30 causes advancement of the plunger 15 and the sliding element 40 approaches the outlet.

Les mâchoires 42 se referment sur la tête 18 ce qui permet de ramener l'élément coulissant 40 en arrière lorsque la deuxième partie 4 est entraínée en rotation en sens inverse.The jaws 42 close on the head 18 which allows to bring back the sliding element 40 back when the second part 4 is rotated reverse.

Les pattes 31 de l'organe d'entraínement présentent une certaine flexibilité dans le sens axial, ce qui autorise un léger enfoncement du bâtonnet de produit P au moment de l'utilisation.The legs 31 of the drive member have a certain flexibility in the axial direction, which allows a slight depression of the product stick P to time of use.

A tout moment l'utilisateur peut remplacer la deuxième partie 4 par une nouvelle recharge de produit ou un produit différent en séparant la première partie 3 de la deuxième partie 4, sans avoir à faire sortir le bâtonnet de produit de la nouvelle recharge.At any time the user can replace the second part 4 with a new product refill or a different product by separating the first part 3 of the second part 4, without having to remove the product stick from the new refill.

Au cours de cette opération, les mâchoires 42 de l'élément coulissant 40 sont ramenées à leur position initiale dans l'embouchure conique 10, ce qui leur permet de libérer la tête 18.During this operation, the jaws 42 of the sliding element 40 are returned to their original position in the conical mouth 10, which allows them to free the head 18.

De façon concomitante, les pattes 31 de l'organe d'entraínement 30 s'écartent grâce à la libération des fentes 14 et libèrent la tige 16 du poussoir 15, lequel est alors ramené dans sa position initiale par l'action de rappel du ressort 26.Concomitantly, the legs 31 of the drive member 30 deviate thanks to the release of the slots 14 and release the rod 16 from the pusher 15, which is then returned to its initial position by the return action of the spring 26.

On a représenté sur la figure 7 un distributeur 50 conforme à un deuxième exemple de réalisation de l'invention.FIG. 7 shows a distributor 50 conforming to a second exemplary embodiment of the invention.

Ce distributeur comporte une première partie 51 et une deuxième partie 52 respectivement analogues à la première partie 3 et la deuxième partie 4 du distributeur 1 précédemment décrit.This distributor comprises a first part 51 and a second part 52 respectively analogous to the first part 3 and the second part 4 of the dispenser 1 previously described.

La première partie 51 est fermée à une extrémité par un bouchon 53, sur la face intérieure duquel est fixé à une extrémité un ressort hélicoïdal 54 travaillant en traction.The first part 51 is closed at one end by a plug 53, on the inner face of which is fixed at one end a helical spring 54 working in traction.

Le distributeur 50 comporte un poussoir 55 présentant un filetage extérieur 56 sur une partie de sa longueur.The distributor 50 comprises a pusher 55 having an external thread 56 over part of its length.

Le poussoir 55 comporte à son extrémité arrière des ailettes 57 coulissant dans des rainures longitudinales 58 de la première partie 51 et à son extrémité avant une tête 59 similaire à la tête 18 du distributeur 1 précédemment décrit.The pusher 55 has, at its rear end, sliding fins 57 in longitudinal grooves 58 of the first part 51 and at its front end a head 59 similar to the head 18 of the dispenser 1 previously described.

Le ressort hélicoïdal 54 est fixé à son extrémité avant 62 dans le fond d'un alésage central 60 du poussoir 55.The coil spring 54 is fixed at its front end 62 in the bottom of a central bore 60 of pusher 55.

Lorsque le poussoir 55 est dans sa position initiale, les ailettes 57 viennent axialement en butée contre le bouchon 53 et le ressort 54 se trouve logé entièrement à l'intérieur de l'alésage central 60.When the pusher 55 is in its initial position, the fins 57 come axially in abutment against the plug 53 and the spring 54 is housed entirely at the interior of the central bore 60.

Le distributeur 50 comporte un organe d'entraínement 65 identique à l'organe d'entraínement 30 du distributeur 1 précédemment décrit.The distributor 50 includes a drive member 65 identical to the member 30 of the distributor 1 previously described.

La deuxième partie 52 du distributeur 50 comporte un élément coulissant 66 qui est agencé pour recevoir un bâtonnet de produit ayant un diamètre relativement important, tel qu'un bâtonnet de rouge à lèvres R.The second part 52 of the distributor 50 has a sliding element 66 which is arranged to receive a rod of product having a relatively large diameter, such as a lipstick stick R.

L'élément coulissant 66 comporte à l'avant comme on peut le voir sur la figure 8 une cupule 67 pourvue de languettes élastiques 68 formant radialement saillie au repos à l'intérieur de la cupule 67, ces languettes étant destinées à renforcer l'ancrage du bâtonnet de produit R. The sliding element 66 has at the front as can be seen in the figure 8 a cup 67 provided with elastic tongues 68 radially projecting at rest inside the cup 67, these tabs being intended to strengthen the anchoring of the product stick R.

L'élément coulissant 66 comporte à l'arrière des mâchoires 69 à l'instar de l'élément coulissant 40 de l'exemple de réalisation précédent.The sliding element 66 has at the rear jaws 69 like the sliding element 40 of the previous embodiment example.

L'élément coulissant 66 peut comporter en outre un orifice dans le fond de la cupule 67 pour le coulage à l'envers du produit à chaud.The sliding element 66 may also include an opening in the bottom of the cup 67 for pouring the product hot upside down.

La deuxième partie 52 est conformée pour permettre l'engagement d'un capuchon de fermeture 70 dont le fond est muni d'un tampon de mousse 71 contre lequel vient appuyer le nez 72 de la deuxième partie 52.The second part 52 is shaped to allow the engagement of a cap closure 70 whose bottom is provided with a foam pad 71 against which supports the nose 72 of the second part 52.

D'une manière générale, de par le fait que dans les exemples décrits le ressort de rappel est logé au moins partiellement dans le poussoir, le distributeur peut présenter un encombrement axial relativement faible.In general, because in the examples described the spring at least partially housed in the pusher, the dispenser may have a relatively small axial size.

On a représenté sur la figure 9 un double distributeur 90 dont le corps présente une partie centrale 91 formée d'une manière générale en réunissant la première partie 51 de deux distributeurs 50 montés en opposition.FIG. 9 shows a double distributor 90 whose body has a central portion 91 generally formed by joining the first part 51 of two distributors 50 mounted in opposition.

Les bouchons 53 sont alors remplacés par une paroi transversale 92 percée d'un orifice 93 permettant de faire communiquer les compartiments 94 et 95 dans lesquels coulissent respectivement les parties arrière des deux poussoirs.The plugs 53 are then replaced by a transverse wall 92 pierced an orifice 93 making it possible to communicate the compartments 94 and 95 in which slide the rear parts of the two pushers respectively.

Dans les exemples de réalisation qui viennent d'être décrits, le ressort utilisé pour ramener le poussoir correspondant dans sa position initiale est fixé par soudure à une extrémité sur ce poussoir et à l'autre extrémité sur le corps du distributeur. On ne sort pas du cadre de l'invention en fixant le ressort par collage, en réalisant l'extrémité du ressort en forme de crochet ou à l'aide de pièces intermédiaires adaptées.In the embodiments which have just been described, the spring used to return the corresponding pusher to its initial position is fixed by welding to one end on this plunger and at the other end on the body of the dispenser. Onne does not depart from the scope of the invention by fixing the spring by gluing, by making the end hook-shaped spring or using suitable intermediate parts.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation illustrés. On peut notamment, sans sortir du cadre de la présente invention, utiliser un organe élastique autre qu'un ressort hélicoïdal.Of course, the invention is not limited to the illustrated exemplary embodiments. One can in particular, without departing from the scope of the present invention, use a elastic member other than a helical spring.

Le bâtonnet de produit peut être remplacé par tout type d'applicateur tel qu'un pinceau, un feutre, une mousse ou un matériau floqué, le produit pouvant être une teinte, un mascara ou une ombre à paupières, parmi d'autres.The product stick can be replaced by any type of applicator such than a paintbrush, felt, foam or flocked material, the product may be a tint, a mascara or an eye shadow, among others.

L'organe d'entraínement peut être constitué, dans une variante non représentée, par un écrou fendu.The drive member can be constituted, in a variant not shown, by a split nut.

Des moyens formant butée, tels que représentés à la figure 5D de la demande WO 98/09548 peuvent être prévus le cas échéant pour limiter le déplacement vers l'arrière de l'élément coulissant.Means forming a stop, as shown in FIG. 5D of the application WO 98/09548 can be provided if necessary to limit movement towards the rear of the sliding element.
