Description

La présente invention concerne un distributeur de produits cosmétiques liquides.The present invention relates to a dispenser of cosmetic products liquids.

Plus précisément, l'invention s'applique aux produits tels que notamment les crèmes, les gels, ainsi que les rouges à lèvres liquides dénommés « gloss » qui se substituent aujourd'hui aux produits traditionnels sous forme solide ou en pâte.More specifically, the invention applies to products such as in particular the creams, gels, as well as liquid lipsticks called "gloss" which today replace traditional products in solid form or into a paste.

En ce qui concerne les « gloss », les différences de densité et de viscosité entre les produits traditionnels et les nouveaux produits rendent les distributeurs téléscopiques à bâton inutilisables et nécessitent de modifier les moyens de distribution et d'application pour satisfaire les conditions de dosage, d'étanchéité et de protection du produit.Regarding the glosses, the differences in density and viscosity between traditional products and new products make them unusable stick telescopic distributors and require modification of the means of distribution and application to satisfy the conditions of dosing, sealing and protection of the product.

Il existe déjà des distributeurs de produits liquides du type comprenant un réservoir, un piston interne et un embout applicateur généralement pourvu d'une valve.There are already distributors of liquid products of the type comprising a reservoir, an internal piston and an applicator tip generally provided a valve.

Cependant, pour des raisons de marketing, il s'avère important de conserver au moins en partie l'aspect général du conditionnement classique de façon à ne pas rompre brutalement avec les habitudes de maquillage des utilisatrices. En particulier, il apparaít essentiel de perpétuer l'usage d'un mouvement rotatif pour assurer la délivrance du produit. However, for marketing reasons, it is important to keep at least in part the general appearance of conventional packaging so as to do not abruptly break users' makeup habits. In particular, it seems essential to perpetuate the use of a movement rotating to ensure product delivery.

Or, du fait de la fluidité du produit, le recours à un tel mouvement pose notamment des problèmes d'étanchéité et de distribution.
Il est nécessaire, notamment, d'assurer la fermeture étanche du distributeur au moyen d'une valve d'extrémité qui s'affranchisse d'une quelconque zone de rétention où un volume résiduel de produit risquerait de séjourner et de sécher.However, due to the fluidity of the product, the use of such a movement poses in particular sealing and distribution problems.
It is necessary, in particular, to ensure the sealed closure of the dispenser by means of an end valve which overcomes any retention zone where a residual volume of product would risk staying and drying out.

La présente invention a pour but de résoudre ces problèmes de manière satisfaisante.The object of the present invention is to solve these problems in such a way satisfactory.

Ce but est atteint, selon l'invention, au moyen d'un distributeur caractérisé en ce que ledit réservoir est constitué d'une embase munie d'une tige axiale sur laquelle ledit piston est déplaçable longitudinalement par rotation de ladite embase relativement audit embout.This object is achieved, according to the invention, by means of a distributor characterized in that said tank consists of a base provided with an axial rod on wherein said piston is movable longitudinally by rotation of said base relative to said end piece.

Selon un mode de réalisation avantageux, ladite valve comprend un ergot central susceptible de venir obturer de manière étanche un orifice d'évacuation ménagé au travers d'une paroi portée par l'extrémité de l'embout.According to an advantageous embodiment, said valve comprises a lug central capable of sealingly closing an orifice evacuation formed through a wall carried by the end of the mouthpiece.

Selon une première variante, ledit ergot est solidaire de l'extrémité de la tige axiale. According to a first variant, said lug is integral with the end of the rod axial.

Selon une seconde variante, ledit ergot est solidaire d'un capot destiné à coiffer ledit embout.According to a second variant, said lug is integral with a cover intended to cap said tip.

Selon une troisième variante, ledit ergot est solidaire d'un manchon interne entourant ledit piston à l'intérieur de l'embout.According to a third variant, said lug is integral with an internal sleeve surrounding said piston inside the tip.

De préférence, ledit manchon se prolonge dans l'embase par une chemise interne.Preferably, said sleeve is extended in the base by a shirt internal.

Le cas échéant, le pourtour de ladite chemise est pourvu d'organes d'encliquetage coopérant avec des organes complémentaires réalisés sur la paroi interne de l'embase.Where appropriate, the periphery of said shirt is provided with members latching cooperating with complementary members made on the inner wall of the base.

Selon une autre caractéristique, ledit piston est constitué d'un collier vissé sur la tige axiale et se prolongeant vers le bas par un flasque cylindrique pourvu à son extrémité inférieure d'une lèvre périphérique en contact étanche avec la paroi interne de l'embout.According to another characteristic, said piston consists of a collar screwed onto the axial rod and extending downwards by a cylindrical flange provided at its lower end of a peripheral lip in tight contact with the inner wall of the nozzle.

Selon encore une autre caractéristique, ledit piston est guidé en translation axiale par des organes de blocage en rotation portés par les parois radialement environnantes.According to yet another characteristic, said piston is guided in translation axial by rotationally locking members carried by the walls radially surrounding.

Parallèlement, la tige axiale est munie de secteurs filetés assurant le vissage du piston tout en permettant le passage du produit. In parallel, the axial rod is provided with threaded sectors ensuring screwing of the piston while allowing the passage of the product.

De préférence, l'embout et l'embase sont assemblés de façon étanche et à bords jointifs.Preferably, the end piece and the base are assembled in a sealed manner and contiguous edges.

Un autre objet de l'invention est un procédé de fabrication et d'assemblage d'un distributeur de produit cosmétique liquide comprenant notamment, une embase formant réservoir, un piston interne muni d'un collier et un embout applicateur, caractérisé en ce que d'une part, on réalise, par moulage d'une matière souple et élastique, un collier porté par ledit piston, et d'autre part, on réalise par moulage d'une matière dure et rigide, une tige axiale, portée par ladite embase et munie d'un filetage, puis on emmanche en force, de façon axiale, la tige dans ledit collier de façon à le mettre en prise avec la tige par ancrage du filetage dans l'épaisseur du collier.Another object of the invention is a method of manufacturing and assembling a liquid cosmetic product dispenser comprising in particular, a base forming a reservoir, an internal piston fitted with a collar and a nozzle applicator, characterized in that on the one hand, a mold is produced flexible and elastic material, a collar carried by said piston, and on the other hand, realizes by molding a hard and rigid material, an axial rod, carried by said base and provided with a thread, then it is force-fitted, so axial, the rod in said collar so as to engage it with the rod by anchoring the thread in the thickness of the collar.

Le distributeur de l'invention présente un aspect général et une ergonomie très proches de ceux des bâtons traditionnels de rouge à lèvres tout en possédant des éléments fonctionnels très différents qui sont adaptés à la nature du produit liquide, à ses propriétés physiques ainsi qu'aux faibles doses qui doivent être délivrées.The dispenser of the invention has a general appearance and ergonomics very close to those of traditional lipstick sticks while having very different functional elements which are adapted to the nature of the liquid product, its physical properties as well as the weak doses to be delivered.

En outre, l'étanchéité du distributeur et le mode de délivrance du produit sont parfaitement compatibles avec les contraintes liées aux cosmétiques liquides. In addition, the watertightness of the dispenser and the method of delivery of the product are perfectly compatible with the constraints linked to liquid cosmetics.

Le distributeur de l'invention a, de plus, une structure très simple avec une variante possible à seulement deux pièces et est donc d'un prix de revient particulièrement économique.The dispenser of the invention has, moreover, a very simple structure with a possible variant with only two pieces and is therefore cost particularly economical.

Enfin, le conditionnement du produit et notamment le remplissage du distributeur s'effectuent facilement avec tous les modes de réalisation, en tirant profit de la position et de la structure de la valve d'extrémité qui permet le dégazage.Finally, the packaging of the product and in particular the filling of the dispenser is easily carried out with all the embodiments, in taking advantage of the position and structure of the end valve which allows degassing.

L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins sur lesquels les figures 1A et 1B représentent respectivement une vue en coupe axiale d'un mode de réalisation du distributeur de l'invention et une vue en coupe transversale selon II de la tige axiale de l'embase.The invention will be better understood on reading the description which follows in reference to the drawings in which FIGS. 1A and 1B represent respectively an axial sectional view of an embodiment of the dispenser of the invention and a cross-sectional view along II of the rod axial of the base.

Les figures 2A et 2B représentent une vue en coupe axiale d'une première variante de réalisation du distributeur de la figure 1A avec le piston respectivement en position haute et en position basse, après vidange du réservoir.Figures 2A and 2B show an axial sectional view of a first alternative embodiment of the dispenser of FIG. 1A with the piston respectively in the high position and in the low position, after emptying the tank.

La figure 3 représente une vue en coupe axiale d'une seconde variante de réalisation du distributeur de l'invention. FIG. 3 represents a view in axial section of a second variant of realization of the distributor of the invention.

La figure 4 représente une vue partielle en coupe axiale d'une troisième variante de réalisation du distributeur de l'invention.FIG. 4 represents a partial view in axial section of a third alternative embodiment of the dispenser of the invention.

Le distributeur représenté sur la figure 1A est destiné au conditionnement et à la délivrance d'un produit cosmétique liquide du type crème ou encore rouge à lèvres « gloss ».The dispenser shown in FIG. 1A is intended for packaging and the delivery of a liquid cosmetic product of the cream or red type lip gloss.

Il comprend un réservoir 1, un piston interne 2, un embout applicateur 3 pourvu d'une valve et un capot de protection 4. Le capot 4 est pourvu, le cas échéant, d'ailettes 40 de retenue et de calage coopérant avec l'embout 3.It includes a reservoir 1, an internal piston 2, an applicator tip 3 provided with a valve and a protective cover 4. The cover 4 is provided, where appropriate, with fins 40 for retaining and wedging cooperating with the nozzle 3.

Selon l'invention, le réservoir 1 est constitué d'une embase 10 sensiblement cylindrique munie d'une tige axiale 11.According to the invention, the reservoir 1 consists of a base 10 substantially cylindrical with an axial rod 11.

Sur la portion en saillie de la tige 11 est monté le piston 2. Le piston 2 est déplaçable axialement le long de cette tige par rotation manuelle de l'embase 1, relativement à l'embout 3, pour mettre le produit sous pression.The piston 2 is mounted on the projecting portion of the rod 11. The piston 2 is axially movable along this rod by manual rotation of the base 1, relative to the nozzle 3, to put the product under pressure.

A cet effet, la tige 11 est munie de secteurs filetés 12 permettant à la fois, le vissage du piston 2 et le passage du produit en direction de la valve, les secteurs 12 étant séparés, le long de la tige 11, par des gorges 13 qui s'étendent au moins sur toute la hauteur filetée de la tige 11. To this end, the rod 11 is provided with threaded sectors 12 allowing both the screwing of the piston 2 and the passage of the product towards the valve, the sectors 12 being separated, along the rod 11, by grooves 13 which extend at least over the entire threaded height of the rod 11.

Dans les modes de réalisation représentés, le déplacement du piston 2 s'effectue du haut vers le bas mais il est possible de prévoir, par symétrie, un fonctionnement inversé en prolongeant le filetage jusqu'en bas de la tige 11 et en emmanchant le piston sur la tige dans l'autre sens.In the embodiments shown, the displacement of the piston 2 is carried out from top to bottom but it is possible to provide, by symmetry, a reverse operation by extending the thread to the bottom of the rod 11 and by pushing the piston on the rod in the other direction.

L'embout 3 et l'embase 1 sont assemblés de façon étanche et à bords jointifs.The end piece 3 and the base 1 are assembled in a sealed manner and with contiguous edges.

Dans le mode de réalisation des figures 1A, 2A et 3, l'embout 3 comporte, au moins à son extrémité, une paroi élastiquement déformable 31 au travers de laquelle est ménagé un orifice d'évacuation 30.In the embodiment of FIGS. 1A, 2A and 3, the end piece 3 comprises, at less at its end, an elastically deformable wall 31 through which is provided with a discharge orifice 30.

La paroi 31 est destinée à l'application du produit, par exemple pour un « gloss », sur les lèvres de l'utilisatrice et possède à cet effet un profil curviligne du type en ogive comme représenté sur les figures ou toute autre forme adaptée à cet usage.The wall 31 is intended for the application of the product, for example for a "Gloss", on the lips of the user and has for this purpose a profile curvilinear type of warhead as shown in the figures or any other form suitable for this use.

De préférence, et en fonction des matériaux choisis, la paroi 31 sera amincie par rapport à l'épaisseur moyenne de la paroi latérale de l'embout pour augmenter sa souplesse et renforcer l'étanchéité.Preferably, and depending on the materials chosen, the wall 31 will be thinned relative to the average thickness of the side wall of the end piece for increase its flexibility and strengthen the seal.

L'embout 3 est associé à une valve d'extrémité garantissant, en position de fermeture, l'étanchéité du distributeur et, en position d'ouverture, l'alimentation régulière et uniforme en produit de la paroi d'application 31. The nozzle 3 is associated with an end valve guaranteeing, in the position of closing, sealing of the dispenser and, in the open position, regular and uniform supply of product to the application wall 31.

Cette valve comprend un ergot 5 formant pointeau susceptible de venir obturer de manière étanche l'orifice 30.This valve comprises a lug 5 forming a needle capable of coming seal port 30.

Dans le mode de réalisation de la figure 1A, l'ergot 5 est solidaire d'un manchon interne coaxial 52 entourant le piston 2 à l'intérieur de l'embout 3 et se prolongeant par une chemise interne 51 doublant la paroi de l'embase 1.In the embodiment of Figure 1A, the lug 5 is secured to a coaxial internal sleeve 52 surrounding the piston 2 inside the end piece 3 and extending by an internal jacket 51 doubling the wall of the base 1.

L'ergot 5 est raccordé au manchon 52 par des entretoises 53 délimitant entre elles des passages pour le produit.The lug 5 is connected to the sleeve 52 by spacers 53 delimiting between they passages for the product.

Dans le mode de réalisation des figures 2A, 2B et 3, l'ergot 5 est directement solidaire de l'extrémité de la tige 11 et il n'est pas prévu de manchon interne. Toutefois, pour des raisons d'étanchéité, la paroi latérale de l'embout 3 est alors prolongée dans l'embase 1 soit par une jupe 35 (figure 2A), soit par la lèvre 21 (figure 3) et comporte un épaulement 34 formant butée à la fois pour le bord supérieur de l'embase et pour le capot 4.In the embodiment of FIGS. 2A, 2B and 3, the lug 5 is directly integral with the end of the rod 11 and an internal sleeve is not provided. However, for sealing reasons, the side wall of the end piece 3 is then extended in the base 1 either by a skirt 35 (FIG. 2A), or by the lip 21 (FIG. 3) and has a shoulder 34 forming a stop for both the upper edge of the base and for the cover 4.

Dans le mode de réalisation de la figure 4, l'ergot 5 est porté par le fond du capot 4 et vient obturer l'orifice 30 par l'extérieur. Sur cette figure la paroi 31 d'application du produit est inclinée à la manière d'un pinceau.In the embodiment of Figure 4, the lug 5 is carried by the bottom of the cover 4 and closes orifice 30 from the outside. In this figure the wall 31 of application of the product is inclined in the manner of a brush.

Sur la figure 1A, le pourtour inférieur de la chemise 51 est pourvu d'organes d'encliquetage 51a coopérant avec des organes complémentaires 1a réalisés sur la paroi de l'embase 1. In FIG. 1A, the lower periphery of the jacket 51 is provided with members latching 51a cooperating with complementary members 1a produced on the wall of the base 1.

Le piston 2 est constitué, en partie haute, d'un collier 20 vissé sur la tige 11 et se prolongeant via un chanfrein 22 par un flasque cylindrique 23 pourvu, en partie basse, d'une lèvre périphérique 21 qui vient ici en contact coulissant et étanche avec la paroi de la chemise 51.The piston 2 consists, in the upper part, of a collar 20 screwed onto the rod 11 and extending via a chamfer 22 by a cylindrical flange 23 provided, in lower part, a peripheral lip 21 which comes here in sliding contact and waterproof with the wall of the jacket 51.

Le flasque 23 a un diamètre intérieur élargi et délimite ainsi, avec la tige 11, en dessous du collier 20 et en complément des gorges 13, un espace de circulation du produit en direction de la valve d'extrémité.The flange 23 has an enlarged internal diameter and thus delimits, with the rod 11, below the collar 20 and in addition to the grooves 13, a space of product flow towards the end valve.

Il est nécessaire de bloquer la rotation du piston 2 pour n'obtenir qu'un déplacement axial guidé le long de la tige 11. A cet effet, le piston 2 est pourvu, le cas échéant, d'organes de blocage en rotation coopérant avec des organes complémentaires portés par les parois radialement environnantes qui sont, sur la figure 1A, celles du manchon 52 et, sur les figures 2A et 2B, celles de l'embout 3.It is necessary to block the rotation of piston 2 to obtain only one guided axial movement along the rod 11. To this end, the piston 2 is provided, where appropriate, with locking members in rotation cooperating with complementary members carried by the walls radially surrounding which are, in FIG. 1A, those of the sleeve 52 and, in FIGS. 2A and 2B, those of the nozzle 3.

Ces organes peuvent être réalisés, comme représentés sur la figure 2B, par exemple, sous forme d'un jeu de nervures longitudinales 33 portées respectivement par les parois en regard du piston 2 et de l'embout 3 et venant en butée les unes contre les autres ou venant se loger dans une ou plusieurs rainures correspondantes de la pièce en regard. These members can be produced, as shown in FIG. 2B, by example, in the form of a set of longitudinal ribs 33 carried respectively by the facing walls of the piston 2 and the end piece 3 and coming in abutment against each other or coming to lodge in one or more corresponding grooves of the facing part.

Dans tous les cas, les dimensions et, en particulier les diamètres du piston 2 et de la tige 11, seront déterminées de façon à réduire au maximum le volume mort intercalaire entre ledit piston et la paroi interne de l'embout 3.
De même, les proportions entre l'ergot 5, la tige 11 et l'embout 3, seront déterminées de façon à minimiser le volume initial situé entre le piston 2 et la valve d'extrémité.In all cases, the dimensions and, in particular the diameters of the piston 2 and of the rod 11, will be determined so as to reduce as much as possible the intermediate dead volume between said piston and the internal wall of the end piece 3.
Similarly, the proportions between the lug 5, the rod 11 and the nozzle 3, will be determined so as to minimize the initial volume located between the piston 2 and the end valve.

L'embout 3 (ou le manchon 52) est muni, en partie haute, d'une butée interne 36 de positionnement axial du piston 2 pour son introduction préalable dans l'embout 3 (ou le manchon 52) en position renversée, avant assemblage avec l'embase 1.The end piece 3 (or the sleeve 52) is provided, in the upper part, with an internal stop 36 for axial positioning of the piston 2 for its prior introduction into the nozzle 3 (or the sleeve 52) in the inverted position, before assembly with base 1.

De préférence, le piston 2 viendra, au moins localement, en contact étanche et coulissant avec la paroi interne du manchon 52 ou de l'embout 3 du fait de l'expansion du collier 20 résultant du vissage sur la tige 11.Preferably, the piston 2 will come, at least locally, into tight contact and sliding with the internal wall of the sleeve 52 or the end piece 3 due to the expansion of the collar 20 resulting from the screwing on the rod 11.

La lèvre périphérique 21 du piston 2 a généralement un profil tronconique. Dans la variante représentée sur la figure 3 la lèvre 21 est raccordée au revers de l'embout 3 qui est replié vers l'intérieur pour former le piston.The peripheral lip 21 of the piston 2 generally has a frustoconical profile. In the variant shown in Figure 3 the lip 21 is connected to the reverse tip 3 which is folded inward to form the piston.

En effet, dans cette variante, l'embout 3 est réalisé initialement d'une seule pièce avec le piston 2 dont il forme le prolongement supérieur. Indeed, in this variant, the end piece 3 is made initially from a single part with the piston 2 of which it forms the upper extension.

Puis au cours du montage, le piston 2 est retourné vers l'intérieur de l'embout 3 en étant en prise par sa partie terminale formant collier sur l'extrémité de la tige 11.Then during assembly, the piston 2 is turned towards the inside of the end piece 3 by being engaged by its terminal part forming a collar on the end of the rod 11.

Il est toutefois possible, dans cette dernière variante, de prévoir une zone de liaison à effet de charnière entre les parties de piston 2 et d'embout 3 pour faciliter le retournement du flasque.It is however possible, in this latter variant, to provide a zone of hinge connection between the piston 2 and end piece 3 parts facilitate flipping the flange.

La rotation de l'embase 1 dans le sens imposé (éventuellement par le biais de dents ou cliquets anti-retour) et relativement à l'embout 3 (ou au manchon 52 solidaire de l'embout 3 - figure 1A), transmet au piston 2, via les secteurs filetés 12, un mouvement de translation axiale qui comprime le produit. Le produit chemine alors par le centre du distributeur, dans les gorges 13 entre les secteurs 12 (et, sur la figure 1A, en outre via les passages entre les entretoises 53) en direction de la valve d'extrémité.The rotation of the base 1 in the imposed direction (possibly by means of teeth or non-return pawls) and relative to the nozzle 3 (or to the sleeve 52 secured to the nozzle 3 - FIG. 1A), transmits to the piston 2, via the sectors threaded 12, an axial translational movement which compresses the product. The product then travels through the center of the distributor, in the grooves 13 between sectors 12 (and, in FIG. 1A, in addition via the passages between the spacers 53) towards the end valve.

Sous la pression du produit, la paroi 31 se déforme élastiquement et libère l'orifice 30 autour de l'ergot 5 en permettant ainsi l'échappement du produit à l'extérieur. Lorsque la pression cesse la paroi 31 revient dans sa position initiale et l'ergot 5 se replace de façon étanche dans l'orifice 30.Under the pressure of the product, the wall 31 deforms elastically and releases the orifice 30 around the lug 5 thereby allowing the product to escape outside. When the pressure ceases the wall 31 returns to its position initial and the lug 5 is replaced tightly in the orifice 30.

De façon à compenser, si nécessaire, le vide crée par l'échappement de produit, il est prévu de ménager un conduit d'évent 32 dans la paroi de l'embout 3ou du manchon 52, au-dessus du niveau de la lèvre 21 du piston 2. In order to compensate, if necessary, the vacuum created by the exhaust of product, it is planned to provide a vent duct 32 in the wall of the end piece 3 or of the sleeve 52, above the level of the lip 21 of the piston 2.

Bien entendu, la hauteur du piston 2 sera déterminée en fonction de la hauteur sur laquelle le produit est stocké dans l'embase 1 de façon à pouvoir distribuer le plus grand volume possible de produit.Of course, the height of the piston 2 will be determined as a function of the height on which the product is stored in the base 1 so that it can distribute the largest possible volume of product.

L'embout 3 ainsi que le piston 2 sont réalisés avec des matériaux thermoplastiques souples et de préférence élastiques ou des élastomères tandis que l'embase 1 et le manchon 52 sont réalisés avec des matériaux plastiques de rigidité et de dureté plus élevées.The nozzle 3 and the piston 2 are made of materials flexible and preferably elastic thermoplastics or elastomers while the base 1 and the sleeve 52 are made with materials plastics of higher rigidity and hardness.

Toutes les pièces constitutives du distributeur de l'invention peuvent être fabriquées au moyen d'un procédé de moulage par injection ou bi-injection. Compte tenu de la nature des matériaux utilisés, l'assemblage du distributeur peut être effectué par emmanchement axial direct de la tige 11 de l'embase 1 dans le piston 2 (avec retournement préalable dans le cas de la figure 3), en bénéficiant du guidage offert par la paroi de l'embout 3.All the constituent parts of the dispenser of the invention can be manufactured using an injection or bi-injection molding process. Given the nature of the materials used, the assembly of the distributor can be performed by direct axial fitting of the rod 11 of the base 1 in piston 2 (with prior turning in the case of FIG. 3), in benefiting from the guidance offered by the wall of the nozzle 3.

Il n'est pas nécessaire, en outre, de prévoir un quelconque filetage sur le piston 2 dans la mesure où le serrage de son collier souple élastique 20, entre l'embout 3 ou le manchon 52, d'une part, et la mise en prise sur les secteurs filetés rigides 12, d'autre part, est à lui seul suffisant pour produire un ancrage du filetage dans l'épaisseur du collier et y former une empreinte de façon à assurer ainsi la transmission du mouvement de rotation. Furthermore, it is not necessary to provide any thread on the piston 2 insofar as the tightening of its flexible elastic collar 20, between the nozzle 3 or the sleeve 52, on the one hand, and the engagement on the sectors rigid threaded 12, on the other hand, is sufficient alone to produce an anchor thread in the thickness of the collar and form an imprint therein so that thus ensuring the transmission of the rotational movement.

De même, avec le mode de réalisation de la figure 1A, il n'est pas nécessaire de prévoir d'organes de blocage en rotation sur le piston lui-même du fait que les organes de blocage portés par la paroi interne en regard du manchon rigide 52 peuvent en interdire la rotation et assurer un guidage axial par simple enfoncement dans la matière souple de la paroi du flasque 23.Likewise, with the embodiment of Figure 1A, it is not necessary to provide locking members in rotation on the piston itself because the locking members carried by the internal wall opposite the rigid sleeve 52 can prohibit rotation and ensure axial guidance by simple sinking into the flexible material of the wall of the flange 23.
