The unit (40) has a deformable zone situated above the former shoulder, where the zone elongates along axis of the rod to vary axial position of the zone where sealing is made.

Description

La présente invention concerne les dispositifs de conditionnement et d'application d'un produit, notamment un produit cosmétique, par exemple du mascara, un vernis à ongles ou un rouge à lèvres liquide.The present invention relates to devices for packaging and applying a product, in particular a cosmetic product, for example mascara, a nail polish or a liquid lipstick.

L'invention a trait plus particulièrement à un dispositif comportant un récipient contenant le produit, un applicateur comportant un élément d'application, un organe de préhension, une tige reliant l'élément d'application à l'organe de préhension et un organe d'essorage agencé pour essorer au moins partiellement l'élément d'application lorsque celui-ci est retiré du récipient. L'organe de préhension peut en outre être sous la forme d'un capuchon pour assurer la fermeture du dispositif, notamment par vissage sur le col du récipient.The invention relates more particularly to a device comprising a receptacle containing the product, an applicator comprising an applicator element, a gripping member, a rod connecting the applicator element to the gripping member, and an applicator member. squeezing arranged to at least partially wring the applicator element when it is removed from the container. The gripping member may also be in the form of a cap for closing the device, in particular by screwing onto the neck of the container.

Pour assurer une fermeture étanche d'un tel dispositif, il est connu par la demande de brevet européen EP 0 740 913 , la demande internationale WO 94/14357 , le brevet US 4 761 088 ou la demande de brevet FR 2 646 066 de réaliser l'organe d'essorage avec une collerette contre laquelle l'organe de préhension vient axialement en appui. En particulier, une portion de l'organe de préhension ou de la tige vient écraser axialement la collerette.To ensure a tight closure of such a device, it is known by the application of European patent EP 0 740 913 , international demand WO 94/14357 , the US Patent 4,761,088 or the request for FR 2,646,066 to achieve the wiper member with a flange against which the gripping member comes axially support. In particular, a portion of the gripping member or the rod axially crushes the collar.

De tels dispositifs peuvent également être fermés de manière étanche par un système d'étanchéité conique, en utilisant par exemple une tige qui comporte une section conique venant en appui étanche contre un cône correspondant présent dans la partie supérieure interne de l'organe d'essorage.Such devices can also be closed in a sealed manner by a conical sealing system, for example using a rod which has a conical section sealingly against a corresponding cone present in the upper internal part of the wringing member. .

Compte tenu des tolérances de fabrication du dispositif, il est relativement difficile de garantir que la portion de la tige ou de l'organe de préhension vienne en appui étanche contre l'organe d'essorage exactement à la fin du vissage du capuchon, en particulier lorsque l'étanchéité est conique. Il est en effet difficile d'ajuster les deux cônes de sorte que le contact ne se fasse pas trop tôt, ce qui empêcherait de terminer le vissage, ou encore trop tard auquel cas il n'y aurait plus contact entre la tige et l'organe d'essorage et donc plus d'étanchéité. La production en grande série de tels dispositifs nécessite donc une grande précision qui génère des coûts relativement importants.Given the manufacturing tolerances of the device, it is relatively difficult to ensure that the portion of the rod or the gripping member comes into sealing engagement against the wiper member exactly at the end of the screwing of the cap, in particular when the seal is conical. It is indeed difficult to adjust the two cones so that the contact is not made too early, which would prevent to finish the screwing, or too late in which case there would be no contact between the rod and the wiper and therefore more sealing. The mass production of such devices therefore requires great precision which generates relatively large costs.

En outre, lorsque l'on utilise une étanchéité conique, le produit déposé par l'élément d'application sur l'organe d'essorage, et donc en partie sur le cône, est chassé au moins partiellement vers le haut lorsque se fait le contact d'étanchéité avec la tige étant donné que la surface de contact est relativement grande et s'étend jusqu'à l'extrémité supérieure de l'organe d'essorage. Après plusieurs utilisations successives, ce dépôt de produit déborde l'extrémité supérieure de l'organe d'essorage pour finalement venir souiller le filetage du col du récipient. Le vissage du capuchon sur le col du récipient devient alors difficile voire même impossible empêchant ainsi la fermeture du récipient.In addition, when using a conical seal, the product deposited by the applicator element on the wiper member, and therefore partly on the cone, is driven at least partially upwards when the sealing contact with the rod as the contact surface is relatively large and extends to the upper end of the wiper member. After several successive uses, this product deposit overflows the upper end of the wiper member to finally soil the thread of the neck of the container. Screwing the cap on the neck of the container becomes difficult or even impossible thus preventing the closure of the container.

Aussi, est-ce un des objets de l'invention que de réaliser un dispositif de conditionnement et d'application qui ne présente pas les inconvénients de la technique antérieure.Also, is it an object of the invention to provide a packaging device and application that does not have the disadvantages of the prior art.

C'est en particulier un objet de l'invention que de réaliser un tel dispositif qui comporte un système d'étanchéité fiable.It is particularly an object of the invention to provide such a device which comprises a reliable sealing system.

C'est aussi un autre objet de l'invention que de réaliser un tel dispositif qui soit simple à mettre en oeuvre industriellement.It is also another object of the invention to provide such a device which is simple to implement industrially.

Selon l'invention, ces objets peuvent être atteints en réalisant un dispositif de conditionnement et d'application d'un produit comportant :

  • un récipient pour contenir le produit, ce récipient présentant une ouverture à son extrémité supérieure,
  • un organe d'essorage engagé au moins partiellement dans l'ouverture,
  • un applicateur comportant un élément d'application porté par une tige d'axe X,
  • un organe de fermeture du récipient,
l'organe d'essorage comportant :
  • une zone d'étanchéité sur laquelle une partie de la tige est apte à venir en contact étanche lorsque l'organe de fermeture est en position de fermeture,
  • une zone de plus grande déformabilité, située au dessus de la zone d'étanchéité, apte à s'étirer axialement lorsque la tige est en appui sur la zone d'étanchéité de l'organe d'essorage.
According to the invention, these objects can be achieved by providing a device for packaging and applying a product comprising:
  • a container for containing the product, which container has an opening at its upper end,
  • a wiper member engaged at least partially in the opening,
  • an applicator comprising an applicator element carried by an X-axis rod,
  • a closure member of the container,
the wringing member comprising:
  • a sealing zone on which a portion of the rod is able to come into sealing contact when the closure member is in the closed position,
  • an area of greater deformability, located above the sealing zone, capable of stretching axially when the rod bears against the sealing zone of the wiper member.

La zone de plus grande déformabilité est une zone de l'organe d'essorage qui se déforme plus que le reste de l'organe d'essorage situé au dessus de la zone d'étanchéité.The zone of greater deformability is an area of the wiper member which deforms more than the rest of the wiper member located above the sealing zone.

Lorsque l'organe de fermeture est en position de fermeture sur le récipient, la zone de plus grande déformabilité peut par exemple s'étirer de 50 % de sa longueur, mesurée selon l'axe de la tige.When the closure member is in the closed position on the container, the zone of greater deformability may for example stretch 50% of its length, measured along the axis of the rod.

La zone de plus grande déformabilité de l'organe d'essorage permet de déplacer axialement la zone d'étanchéité sur laquelle se fait l'étanchéité de sorte que le dispositif est plus tolérant. La mise au point et les conditions de production sont ainsi facilitées ce qui facilite l'industrialisation du dispositif.The zone of greater deformability of the wiper member makes it possible to axially move the sealing zone on which the seal is made so that the device is more tolerant. The development and production conditions are thus facilitated which facilitates the industrialization of the device.

L'organe d'essorage peut comporter une zone d'essorage formée à distance de la zone d'étanchéité. En particulier, la zone d'étanchéité est située à une distance suffisante de la zone d'essorage pour ne pas que la zone d'essorage se déforme lorsque la tige est en appui étanche sur la zone d'étanchéité. La fonction d'essorage et la fonction d'étanchéité de l'organe d'essorage sont en outre parfaitement séparées.The wiper member may comprise a wiping zone formed at a distance from the sealing zone. In particular, the sealing zone is located at a sufficient distance from the wiping zone so as not to cause the wiping zone to deform when the rod bears tightly against the sealing zone. The spin function and the sealing function of the wiper member are furthermore perfectly separated.

La zone d'étanchéité peut être formée à une distance de l'extrémité supérieure de l'organe d'essorage. La tige venant en contact étanche contre une petite surface formée à distance de l'extrémité supérieure de l'organe d'essorage, le produit restant sur l'organe d'essorage n'est pas chassé vers l'extérieur du récipient ce qui évite l'encrassement de l'extérieur du récipient.The sealing zone may be formed at a distance from the upper end of the wiper member. The rod coming into sealing contact against a small surface formed at a distance from the upper end of the wiper member, the product remaining on the wiper member is not forced out of the container which avoids fouling of the outside of the container.

La zone de plus grande déformabilité de l'organe d'essorage peut comporter une plus faible épaisseur que le reste de l'organe d'essorage situé au dessus de la zone d'étanchéité. La zone de plus grande déformabilité de l'organe d'essorage a par exemple une épaisseur inférieure à 1 mm et de préférence inférieure à 0,6 mm.The zone of greater deformability of the wiper member may comprise a smaller thickness than the rest of the wiper member situated above the sealing zone. The zone of greater deformability of the wiper member has for example a thickness of less than 1 mm and preferably less than 0.6 mm.

Alternativement ou en complément, la zone de plus grande déformabilité peut être réalisée en un matériau différent du matériau constituant le reste de l'organe d'essorage, le matériau de la zone de plus grande déformabilité présentant une plus grande déformabilité que le matériau constituant le reste de l'organe d'essorage.Alternatively or in addition, the zone of greater deformability may be made of a material different from the material constituting the remainder of the wiper member, the material of the zone of greater deformability having a greater deformability than the material constituting the rest of the wiper.

La zone d'étanchéité de l'organe d'essorage peut être délimitée par un épaulement. L'épaulement peut s'étendre radialement vers l'intérieur de l'organe d'essorage en délimitant une surface annulaire perpendiculaire à l'axe X de la tige. En variante, l'épaulement peut délimiter une surface tronconique convergeant vers l'ouverture du récipient. Une telle forme permet de compenser les éventuelles déformations de l'épaulement de l'organe d'essorage lorsque la tige vient exercer une force dirigée vers l'extrémité inférieure de l'organe d'essorage.The sealing zone of the wiper member may be delimited by a shoulder. The shoulder may extend radially inwardly of the wiper member by delimiting an annular surface perpendicular to the axis X of the rod. Alternatively, the shoulder may delimit a frustoconical surface converging towards the opening of the container. Such a shape makes it possible to compensate for any deformations of the shoulder of the wiper member when the rod exerts a force directed towards the lower end of the wiper member.

La tige peut comporter un épaulement destiné à venir en appui sur la zone d'étanchéité de l'organe d'essorage.The rod may comprise a shoulder intended to bear against the sealing zone of the wiper member.

Le récipient peut comporter un col dans lequel est engagé au moins partiellement l'organe d'essorage.The container may comprise a neck in which is engaged at least partially the wiper member.

L'organe d'essorage peut être réalisé dans un matériau élastomère ou dans une polyoléfine, notamment du polyéthylène.The wiper member may be made of an elastomeric material or a polyolefin, especially polyethylene.

La zone d'essorage peut définir un orifice circulaire de diamètre adapté à celui de la tige à essorer.The spinning zone can define a circular orifice of diameter adapted to that of the squeezing rod.

Le diamètre de l'orifice défini par la zone d'essorage peut être inférieur ou égal au diamètre de la portion de tige à son contact lorsque le dispositif est fermé.The diameter of the orifice defined by the wiping zone may be less than or equal to the diameter of the rod portion on contact when the device is closed.

La zone d'essorage peut être une lèvre.The spinning zone can be a lip.

L'élément d'application peut être une brosse, un peigne ou encore comporter un embout en mousse.The application element may be a brush, a comb or may comprise a foam tip.

Le récipient peut contenir un produit cosmétique, notamment du mascara.The container may contain a cosmetic product, including mascara.

L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

Le récipient 20 comporte un corps 21 contenant le produit, muni dans l'exemple considéré en partie supérieure d'un col 22, fileté extérieurement dans l'exemple illustré. L'extrémité supérieure du col définit une ouverture dans laquelle est engagé l'organe d'essorage 40.The container 20 comprises a body 21 containing the product, provided in the example considered in the upper part of a neck 22, threaded externally in the example illustrated. The upper end of the neck defines an opening in which is engaged the wiper member 40.

L'applicateur 30 comporte une tige 31 d'axe X, de section circulaire sur sensiblement toute sa longueur dans l'exemple considéré, munie à son extrémité inférieure d'un élément d'application 32 constitué dans l'exemple illustré par une brosse à âme torsadée.The applicator 30 comprises a rod 31 of axis X, of circular section over substantially its entire length in the example considered, provided at its lower end with an applicator element 32 constituted in the example illustrated by a brush with twisted soul.

La tige 31 se raccorde à son extrémité supérieure à un organe de préhension 50 constituant également un organe de fermeture du récipient 20.The rod 31 is connected at its upper end to a gripping member 50 also constituting a closure member of the container 20.

The skirt tubular 54 and the rod 31 are interconnected by an annular wall 56 extending transversely with respect to the axis X.

La jupe tubulaire 54 est filetée sur sa surface intérieure pour permettre le vissage de l'organe de fermeture sur le col du flacon. La jupe 54 et le col 22 comportent en outre sous leur filetage respectif un relief, non représenté, les deux reliefs étant prévus pour coopérer entre eux pour marquer la fin du vissage. En particulier, le relief prévu sur la jupe est prévu pour venir au contact du relief prévu sur le col lors du vissage du capot sur le récipient et pour le franchir en le déformant élastiquement de manière à produire un signal sonore en fin de vissage.The tubular skirt 54 is threaded on its inner surface to allow screwing of the closure member on the neck of the bottle. The skirt 54 and the neck 22 further comprise under their respective threading a relief, not shown, the two reliefs being provided to cooperate with each other to mark the end of the screwing. In particular, the relief provided on the skirt is provided to come into contact with the relief provided on the neck during screwing of the cap on the container and to cross it by deforming it elastically so as to produce a sound signal at the end of screwing.

En se reportant maintenant aux figures 2 et 3, on peut voir que l'organe d'essorage 40 comporte un corps 41 venant s'appliquer sur la surface intérieure du col 22. Ce corps 41 peut comporter des moyens de retenue sur le récipient 20, ces moyens de retenue comportant par exemple comme illustré un relief tel qu'un bourrelet annulaire 42 agencé pour se loger dans une gorge correspondante de la surface intérieure du col 22.Referring now to FIGS. 2 and 3, it can be seen that the wiper member 40 comprises a body 41 which is applied to the inner surface of the neck 22. This body 41 may comprise retaining means on the container 20 , these retaining means comprising for example as illustrated a relief such an annular bead 42 arranged to fit in a corresponding groove of the inner surface of the neck 22.

En partie supérieure, l'organe d'essorage 40 comporte une collerette 43 venant en appui sur l'extrémité supérieure 23 du col 22. L'organe d'essorage 40 comporte en partie inférieure une lèvre annulaire d'essorage 44, définissant un orifice de section circulaire, cette lèvre 44 étant agencée pour s'appliquer sur la tige 31 et/ou l'élément d'application 32 lors du retrait de l'applicateur 30 hors du récipient. En particulier, la lèvre 44 définit un orifice circulaire de diamètre sensiblement égal à celui de la portion de la tige sur laquelle elle est en contact lorsque le dispositif est fermé.In the upper part, the wiper member 40 comprises a flange 43 bearing on the upper end 23 of the neck 22. The wiper member 40 comprises in the lower part an annular wringing lip 44, defining an orifice of circular section, this lip 44 being arranged to be applied on the rod 31 and / or the applicator element 32 during removal of the applicator 30 from the container. In particular, the lip 44 defines a circular orifice of diameter substantially equal to that of the portion of the rod on which it is in contact when the device is closed.

L'organe d'essorage 40 peut être réalisé par exemple dans un matériau élastomère ou dans une polyoléfine, notamment du polyéthylène ou toute autre matière plastique. Dans l'exemple illustré, l'organe d'essorage 40 est réalisé en un seul matériau.The wiper member 40 may be made for example of an elastomeric material or a polyolefin, especially polyethylene or any other plastic material. In the example illustrated, the wiper member 40 is made of a single material.

Pour assurer la fermeture étanche du récipient, lorsque le dispositif 10 est fermé, on prévoit que la tige vienne en appui étanche contre l'organe d'essorage.To ensure the tight closure of the container, when the device 10 is closed, it is expected that the rod comes into sealing engagement against the wiper member.

A cet effet, la tige comporte un épaulement annulaire 33, destiné à venir en appui sur un épaulement annulaire 45 formé dans l'organe d'essorage lorsque l'organe de fermeture est vissé sur le récipient. L'épaulement 33 formé dans la tige, délimite une surface annulaire, tournée vers la brosse 32, qui s'étend dans un plan perpendiculaire à l'axe X de la tige. L'épaulement 45 formé dans l'organe d'essorage, délimite également une surface annulaire, tournée vers l'extrémité supérieure de l'organe d'essorage, qui s'étend également dans un plan perpendiculaire à l'axe X de la tige.For this purpose, the rod comprises an annular shoulder 33 intended to bear against an annular shoulder 45 formed in the wiper member when the closure member is screwed onto the container. The shoulder 33 formed in the rod defines an annular surface facing the brush 32, which extends in a plane perpendicular to the axis X of the rod. The shoulder 45 formed in the wiper member also defines an annular surface, facing the upper end of the wiper member, which also extends in a plane perpendicular to the axis X of the rod .

Selon une variante représentée sur la figure 4, les épaulements 33 et 45 définissent, non pas une surface annulaire perpendiculaire à l'axe X, mais une surface tronconique qui converge vers l'axe X.According to a variant shown in Figure 4, the shoulders 33 and 45 define, not an annular surface perpendicular to the axis X, but a frustoconical surface which converges towards the axis X.

Pour améliorer encore le contact étanche entre la tige et l'organe d'essorage, on peut en outre prévoir un godron 34 sur l'épaulement 33 de la tige, comme on l'a représenté sur la figure 3. Le godron 34 est destiné à venir écraser sensiblement l'épaulement 45 de l'organe d'essorage.To further improve the sealing contact between the rod and the wiper member, it is further possible to provide a godron 34 on the shoulder 33 of the rod, as shown in FIG. 3. The godron 34 is intended to to come substantially crush the shoulder 45 of the wiper member.

Le contact entre les deux épaulements 33 et 45 permet d'assurer l'étanchéité de la fermeture du dispositif lorsque l'applicateur est en position de stockage sur le récipient. On peut alors parfaitement conserver le produit à l'intérieur du récipient. En outre, la tige venant en contact étanche contre une surface annulaire formée sensiblement perpendiculairement à l'axe de la tige ou de façon oblique, le produit restant sur l'organe d'essorage ne sera pratiquement pas poussé vers l'extrémité supérieure de l'organe d'essorage au moment où se fait le contact étanche. En outre, même si du produit est poussé vers l'extrémité supérieure de l'organe d'essorage, il n'est pas chassé vers l'extérieur du récipient puisque le contact étanche est réalisé à distance de l'extrémité supérieure de l'organe d'essorage.The contact between the two shoulders 33 and 45 makes it possible to seal the closure of the device when the applicator is in the storage position on the container. It can then perfectly keep the product inside the container. In addition, the rod coming into sealing contact against an annular surface formed substantially perpendicular to the axis of the rod or obliquely, the product remaining on the wiper member will be practically not pushed towards the upper end of the rod. wiper member at the moment when the watertight contact is made. In addition, even if the product is pushed towards the upper end of the wiper member, it is not pushed towards the outside of the container since the sealing contact is made at a distance from the upper end of the wiper member. wringing member.

Pour garantir que les deux épaulements viennent bien en appui étanche l'un contre l'autre à la fin du vissage, en particulier juste après le signal sonore, l'organe d'essorage 40 comporte avantageusement une zone déformable 46 qui peut s'étirer selon l'axe de la tige de manière à faire varier sensiblement la position axiale de la zone où est réalisée l'étanchéité.To ensure that the two shoulders come into tight abutment against each other at the end of the screwing, in particular just after the audible signal, the wiper member 40 advantageously comprises a deformable zone 46 which can stretch along the axis of the rod so as to substantially vary the axial position of the zone where the seal is made.

La position relative des épaulements peut ainsi être déterminée avec une plus grande tolérance. En particulier, on peut prévoir que les deux épaulements viennent au contact l'un de l'autre sensiblement avant la fin du vissage de l'organe de fermeture. Une fois que les épaulements sont au contact l'un de l'autre, le vissage de l'organe de fermeture est encore possible grâce à l'étirement de la zone déformable de l'organe d'essorage qui permet à la tige de déplacer l'épaulement 45 de l'organe d'essorage vers le bas.The relative position of the shoulders can thus be determined with greater tolerance. In particular, it can be provided that the two shoulders come into contact with each other substantially before the end of the screwing of the closure member. Once the shoulders are in contact with each other, the tightening of the closure member is still possible thanks to the stretching of the deformable zone of the wiper member which allows the rod to move. the shoulder 45 of the wiper member downwards.

Dans l'exemple illustré sur les figures 1, 2A et 2B, la zone déformable 46 est constituée par une paroi de plus fine épaisseur, située au-dessus de l'épaulement 45. Lorsque l'organe de fermeture est vissé sur le flacon la paroi 46 est étirée selon l'axe de la tige, comme on l'a illustré à la figure 2A. Lorsque l'on dévisse l'organe de fermeture, la paroi 46 se rétracte, comme on l'a illustré à la figure 2B.In the example illustrated in FIGS. 1, 2A and 2B, the deformable zone 46 is constituted by a wall of thinner thickness, situated above the shoulder 45. When the closure member is screwed onto the bottle the wall 46 is stretched along the axis of the rod, as illustrated in Figure 2A. When unscrewing the closure member, the wall 46 retracts, as illustrated in Figure 2B.

Selon un exemple particulier, la paroi 46 a une épaisseur de 0,4 mm, alors que le corps 41 de l'organe d'essorage a une épaisseur de 1,2 mm et que l'épaisseur de l'organe d'essorage au niveau de l'épaulement 45 est environ égale à 1,5 mm. Lorsqu'elle n'est pas étirée, notamment lorsque l'organe de fermeture est dévissé, la paroi 46 a par exemple une longueur, mesurée selon l'axe X, environ égale à 2 mm. Lorsque l'organe de fermeture est vissé, la paroi 46 étirée présente une longueur environ égale à 3 mm.In a particular example, the wall 46 has a thickness of 0.4 mm, while the body 41 of the wiper member has a thickness of 1.2 mm and that the thickness of the wiper member at level of the shoulder 45 is approximately equal to 1.5 mm. When not stretched, especially when the closure member is unscrewed, the wall 46 has for example a length, measured along the axis X, approximately equal to 2 mm. When the closure member is screwed, the stretched wall 46 has a length of about 3 mm.

La zone déformable de l'organe d'essorage peut, en variante, être constituée par une paroi, de même épaisseur que le reste de l'organe d'essorage, mais en matériau plus déformable que celui dans lequel est réalisé le reste de l'organe d'essorage, comme on l'a illustré sur la figure 4. La zone déformable peut par exemple être réalisée en élastomère thermoplastique, notamment en PP/SBS, en PP/SEBS, en polyéthylène de très basse densité tel que les métallocènes, en PET élastomère tel que l'Arnitel® ou en NBR. Selon une autre variante, on peut aussi prévoir que la zone déformable est constituée par une paroi de plus faible épaisseur ainsi que dans un matériau différent du reste de l'organe d'essorage.The deformable zone of the wiper member may alternatively be constituted by a wall of the same thickness as the rest of the wiper member, but of more deformable material than that in which the rest of the wiper is made. wiper member, as illustrated in Figure 4. The deformable zone may for example be made of thermoplastic elastomer, especially PP / SBS, PP / SEBS, very low density polyethylene such as metallocenes elastomeric PET such as Arnitel® or NBR. According to another variant, it can also be provided that the deformable zone is constituted by a wall of smaller thickness and in a material different from the rest of the wiper member.

La zone déformable de l'organe d'essorage peut aussi comporter des renforts sur sa paroi extérieure qui empêchent toute déformation autre que selon l'axe X de la zone déformable. On peut par exemple prévoir des ailettes longitudinales s'étendant parallèlement à l'axe X pour éviter que la zone déformable ne se vrille mais qui autorisent son étirement.The deformable zone of the wiper member may also comprise reinforcements on its outer wall which prevent any deformation other than along the X axis of the deformable zone. One can for example provide longitudinal fins extending parallel to the axis X to prevent the deformable zone is twisted but allow its stretching.

L'élément d'application 32 peut être constitué par autre chose qu'une brosse, et notamment, comme illustré sur la figure 5, par un embout qui peut être floqué ou non et comporter ou non une mousse ou, comme illustré sur la figure 6, par un peigne. Ce dernier peut par exemple être réalisé d'une seule pièce par moulage avec la tige et l'organe de préhension.The applicator element 32 may consist of something other than a brush, and in particular, as illustrated in FIG. 5, by a tip which may or may not be flocked and may or may not comprise a foam or, as illustrated in FIG. 6, by a comb. The latter can for example be made in one piece by molding with the rod and the gripping member.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the embodiments which have just been described.

On peut aussi par exemple donner au récipient ou à l'organe de préhension d'autres formes encore.It is also possible for example to give the container or the gripping member other shapes.

La fixation de l'applicateur sur le récipient peut se faire d'une autre manière que par vissage. Par exemple, la fermeture du dispositif peut se faire par encliquetage de l'organe de préhension sur le col du récipient, la surface intérieure de la jupe tubulaire présentant une gorge annulaire et le col un bourrelet correspondant.Fixing the applicator on the container can be done in another way that by screwing. For example, the closure of the device can be done by snapping the gripping member on the neck of the container, the inner surface of the tubular skirt having an annular groove and the neck a corresponding bead.

On ne sort pas non plus du cadre de la présente invention si l'applicateur comporte un élément d'application différent de ceux qui viennent d'être décrits, par exemple un pinceau.It is not beyond the scope of the present invention if the applicator comprises an application element different from those just described, for example a brush.
