Description

La présente invention concerne un dispositif applicateur de produit fluide comprenant un réservoir de produit fluide, une embase de fixation montée sur le réservoir et un organe d'obturation apte à obturer un orifice formé par l'embase, l'organe d'obturation comprenant un élément de prélèvement et/ou d'application qui s'étend à travers l'orifice de l'embase jusque dans le réservoir. Les domaines privilégiés d'application de la présente invention sont ceux de la cosmétique, de la parfumerie ou encore de la pharmacie. D'autres domaines techniques peuvent toutefois être concernés.The present invention relates to a fluid product applicator device comprising a reservoir of fluid product, a fixing base mounted on the reservoir and a closure member adapted to close an orifice formed by the base, the closure member comprising a sampling and / or application element which extends through the orifice of the base into the reservoir. The preferred fields of application of the present invention are those of cosmetics, perfumery or even pharmacy. However, other technical fields may be involved.

Dans l'art antérieur, on connaît déjà le document WO 2005/105598 qui décrit un dispositif applicateur qui est plus particulièrement destiné au domaine spécifique des échantillons de parfum. Le réservoir se présente sous la forme d'un petit flacon, par exemple en verre, comprenant un col définissant une paroi interne délimitant une ouverture faisant communiquer l'intérieur du réservoir avec l'extérieur. Le dispositif applicateur de ce document comprend également une embase de fixation, par exemple en matière plastique, montée de manière étanche sur le col du réservoir. L'embase définit un orifice à travers lequel s'étend l'organe d'obturation. Cet organe d'obturation comprend une partie de préhension par laquelle l'utilisateur peut saisir l'organe d'obturation, ainsi qu'un élément de prélèvement et/ou d'application de produit fluide qui s'étend à travers l'orifice de l'embase jusque dans le réservoir. L'extrémité libre de l'élément de prélèvement est plongée dans le produit fluide stocké dans le réservoir. Ainsi, l'élément de prélèvement permet de prélever du produit fluide à partir du réservoir. L'organe d'obturation peut être retiré de l'embase de fixation en tirant l'élément de prélèvement hors du réservoir à travers l'orifice de l'embase. Ensuite, l'utilisateur peut appliquer le produit fluide de l'élément de prélèvement sur la surface d'application souhaitée. Lorsqu'il s'agit de parfum, l'élément de prélèvement peut se présenter sous la simple forme d'une petite tige de matière plastique sur laquelle une petite quantité de parfum peut se fixer. L'élément de prélèvement peut se présenter sous d'autres formes permettant un prélèvement plus important de produit fluide.In the prior art, the document is already known WO 2005/105598 which describes an applicator device which is more particularly intended for the specific field of perfume samples. The reservoir is in the form of a small bottle, for example glass, comprising a neck defining an inner wall defining an opening communicating the interior of the tank with the outside. The applicator device of this document also comprises a fixing base, for example of plastic, mounted in a sealed manner on the neck of the reservoir. The base defines an orifice through which the shutter member extends. This closure member comprises a gripping portion through which the user can grasp the closure member, and a sampling and / or fluid application member which extends through the orifice of the base in the tank. The free end of the sampling element is immersed in the fluid product stored in the reservoir. Thus, the sampling element makes it possible to take fluid from the reservoir. The closure member may be removed from the attachment base by pulling the sample element out of the reservoir through the orifice of the base. Then, the user can apply the fluid product of the sample element to the desired application surface. When it comes to perfume, the sampling element can be in the form of a small plastic stem on which a small amount of perfume can be attached. The sampling element may be in other forms allowing a larger sample of fluid.

Cependant, dans certains cas d'application, il faut que la quantité de produit fluide prélevée soit suffisante, mais pas excessive. D'autre part, il peut également être important de répartir de manière uniforme le produit fluide sur une certaine longueur de l'élément de prélèvement. Dans d'autre cas, il faut tout simplement éviter tout risque de perte de gouttes de produit fluide une fois l'élément de prélèvement extrait de son réservoir. Ces différents problèmes doivent être résolus sans pour autant augmenter le coût de fabrication du dispositif applicateur, ni son montage.However, in some cases of application, it is necessary that the amount of fluid collected is sufficient, but not excessive. On the other hand, it may also be important to evenly distribute the fluid over a certain length of the sampling member. In other cases, it is simply necessary to avoid any risk of loss of drops of fluid once the sample element extracted from its reservoir. These various problems must be solved without increasing the cost of manufacture of the applicator device or its assembly.

Pour ce faire, la présente invention propose un dispositif applicateur de produit fluide comprenant un réservoir de produit fluide comprenant un col définissant une paroi interne délimitant une ouverture, une embase de fixation montée de manière étanche sur le col du réservoir, l'embase définissant un orifice, et un organe d'obturation apte à obturer l'orifice de l'embase, l'organe d'obturation comprenant un élément de prélèvement et/ou d'application de produit fluide qui s'étend à travers l'orifice de l'embase dans le réservoir, dans lequel l'embase forme de manière monobloc des moyens d'essorage pour essorer l'élément de prélèvement et/ou d'application lors de son retrait du réservoir, caractérisé en ce que les moyens d'essorage sont déplaçables entre une position initiale avant montage sur le col et une position finale après montage sur le col, les moyens d'essorage étant contraints dans la position finale par le col du réservoir.To do this, the present invention provides a fluid product applicator device comprising a fluid reservoir comprising a neck defining an inner wall defining an opening, an attachment base sealingly mounted on the neck of the reservoir, the base defining a orifice, and a closure member adapted to close the orifice of the base, the closure member comprising a sampling member and / or fluid application that extends through the orifice of the base in the tank, in which the base forms in one-piece manner the dewatering means for dewatering the sampling and / or application element when it is withdrawn from the tank, characterized in that the dewatering means are movable between an initial position before mounting on the neck and a final position after mounting on the neck, the dewatering means being forced into the final position by the neck of the tank.

Du fait que les moyens d'essorage font partie intégrante de l'embase, il n'y a pas de pièce supplémentaire à monter dans le dispositif applicateur. C'est le simple montage de l'embase sur le col du réservoir qui va mettre en place les moyens d'essorage à l'intérieur du réservoir.Because the wiping means are an integral part of the base, there is no additional piece to be mounted in the applicator device. It is the simple assembly of the base on the neck of the tank which will set up the means of spinning inside the tank.

Avantageusement, les moyens d'essorage sont contraints dans la position finale par la paroi interne du col. En variante ou en complément, il est possible de contraindre les moyens d'essorage par le bord supérieur du col.Advantageously, the dewatering means are constrained in the final position by the inner wall of the neck. As a variant or in addition, it is possible to constrain the dewatering means by the upper edge of the neck.

Selon une forme de réalisation pratique, les moyens d'essorage peuvent comprendre plusieurs pattes qui sont déplaçables radialement vers l'intérieur vers l'élément de prélèvement et/ou d'application par contact avec le col. Avantageusement, les pattes définissent des extrémités supérieures de jonction et des extrémités inférieures libres, ces extrémités libres étant déplaçables radialement vers l'intérieur par pivotement des pattes autour des extrémités de jonction. Avantageusement, chaque patte comprend un profil de came externe à proximité de son extrémité de jonction, ce profil de came venant en prise avec la paroi interne du col pour faire pivoter l'extrémité libre de la patte vers l'intérieur. De préférence, les extrémités libres des pattes sont séparées les unes des autres par des fentes en position initiale, et sont sensiblement jointives en position finale pour définir ensemble une couronne d'essorage. Le nombre de pattes, et par conséquent de fentes, peut varier de deux à plus d'une dizaine. Les pattes peuvent être rigides ou indéformables en elles-mêmes, mais cependant déplaçables par pivotement au niveau de leurs extrémités supérieures de jonction avec le reste de l'embase de fixation. La rigidité des pattes permet de créer en position finale de montage une couronne d'essorage rigide qui n'a pas tendance à se déformer lors de l'opération d'essorage de l'élément de prélèvement. Il n'est cependant pas exclu de réaliser les pattes, ou plus généralement les moyens d'essorage, de manière à être au moins localement déformables, par exemple par flexion.According to a practical embodiment, the dewatering means may comprise a plurality of lugs which are movable radially inwards towards the sampling and / or application element by contact with the neck. Advantageously, the tabs define upper ends of junction and lower free ends, these free ends being movable radially inwardly by pivoting tabs around the joining ends. Advantageously, each tab comprises an outer cam profile near its junction end, this cam profile engaging with the inner wall of the neck to rotate the free end of the tab inwardly. Preferably, the free ends of the tabs are separated from each other by slots in the initial position, and are substantially contiguous in the final position to define together a spin ring. The number of legs, and therefore of slots, can vary from two to more than ten. The tabs may be rigid or indeformable in themselves, but nevertheless movable by pivoting at their upper ends junction with the rest of the mounting base. The rigidity of the tabs makes it possible to create in the final assembly position a rigid wringing ring which does not tend to deform during the dewatering operation of the sampling element. However, it is not excluded to make the tabs, or more generally the dewatering means, so as to be at least locally deformable, for example by bending.

Selon une autre caractéristique intéressante de l'invention, la paroi interne du col comprend un chanfrein interne d'entrée pour initier le déplacement des moyens d'essorage de leur position initiale vers leur position finale. Le chanfrein d'entrée évite non seulement que les moyens d'essorage, par exemple les pattes, ne buttent franchement sur le bord supérieur du col, mais assure également que les moyens d'essorage vont être déplacés de manière appropriée pour parvenir à leur position finale de montage dans laquelle ils forment la couronne d'essorage. Ce chanfrein d'entrée remplit donc une double fonction.According to another advantageous feature of the invention, the inner wall of the neck comprises an internal inlet chamfer to initiate the displacement of the wiping means from their initial position to their final position. The entry chamfer not only prevents the drying means, for example the legs, positively abut on the upper edge of the neck, but also ensures that the spinning means will be moved appropriately to reach their position final assembly in which they form the wringing crown. This chamfer input thus fulfills a dual function.

Selon un autre aspect intéressant de la présente invention, l'embase comporte une jupe d'étanchéité apte à venir en contact étanche avec la paroi interne du col, les moyens d'essorage étant formés de manière monobloc dans le prolongement de la jupe. On pourrait également considérer que les moyens d'essorage, particulièrement lorsqu'ils sont réalisés sous la forme de pattes séparées par des fentes, font partie intégrante de la jupe qui peut ainsi être divisée en deux sections, à savoir une section supérieure rigide continue, et une section inférieure discontinue qui est déformable radialement vers l'intérieur.According to another interesting aspect of the present invention, the base comprises a sealing skirt adapted to come into sealing contact with the wall internal collar, the dewatering means being integrally formed in the extension of the skirt. It could also be considered that the dewatering means, particularly when made in the form of tabs separated by slots, form an integral part of the skirt which can thus be divided into two sections, namely a continuous rigid upper section, and a discontinuous lower section which is deformable radially inwardly.

Selon un mode de réalisation pratique, ladite embase et ledit organe d'obturation sont réalisés de manière monobloc en étant reliés l'un à l'autre par un pont de matière cassable lors d'une première utilisation. Avantageusement, l'orifice de l'embase est délimité par un bord périphérique relié par ledit pont de matière à une surface de jonction de l'élément de prélèvement et/ou d'application, ledit bord périphérique venant en contact étanche contre une surface d'étanchéité dudit élément de prélèvement et/ou d'application après une rupture dudit pont de matière. Il est ainsi possible de réaliser de manière monobloc l'organe d'obturation et l'embase qui forment les moyens d'essorage. De plus, l'organe d'obturation, après son premier retrait de l'embase, est repositionnable sur l'embase de manière étanche et avantageusement cliquetée.According to a practical embodiment, said base and said closure member are made integrally by being connected to each other by a brittle material bridge during a first use. Advantageously, the orifice of the base is delimited by a peripheral edge connected by said material bridge to a junction surface of the sampling element and / or application, said peripheral edge coming into sealing contact against a surface of sealing said sampling element and / or application after a rupture of said material bridge. It is thus possible to produce in one piece the closure member and the base which form the dewatering means. In addition, the closure member, after its first withdrawal from the base, is repositionable on the base sealingly and advantageously ratchet.

L'invention sera plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.The invention will be more fully described with reference to the accompanying drawings giving by way of non-limiting example an embodiment of the invention.

En référence aux figures, le distributeur de produit fluide de l'invention comporte un réservoir 1 sur lequel est monté un bouchon, qui comprend une embase de fixation 2 et un organe d'obturation 3.With reference to the figures, the fluid dispenser of the invention comprises a reservoir 1 on which a stopper is mounted, which comprises a fixing base 2 and a shutter member 3.

Le réservoir 1 est destiné à contenir du produit fluide, tel qu'un vernis ou brillant à lèvres (gloss), un mascara, une pommade, une crème, une lotion ou un parfum. Il peut être réalisé en verre ou en plastique. Le réservoir 1 comporte un col 11 formant une ouverture 10 faisant communiquer l'intérieur du réservoir avec l'extérieur. Le col 1 comporte une paroi interne 1 délimitant l'ouverture 10 du col, une extrémité supérieure 13 et une paroi externe 15. Un rebord d'accrochage 16 est ménagé au niveau de la paroi externe 15 : ce rebord va servir à la fixation de l'embase 2. Le col 11 forme aussi un chanfrein d'entrée 14 qui relie l'extrémité supérieure 13 à la paroi interne 12. Ce chanfrein 14 facilite le montage de l'embase sur le col 11, mais remplit encore une autre fonction, comme on le verra ci-après. En dessous du rebord 16, le col 11 forme un rétrécissement avant de s'élargir à nouveau en formant un épaulement 17. Ensuite, le réservoir comprend un fût 18, obturé par un fond 19. La paroi externe du fût 18 peut par exemple être circulaire cylindrique. La contenance du réservoir est généralement de l'ordre de quelques millilitres.The reservoir 1 is intended to contain fluid, such as a varnish or gloss (gloss), a mascara, an ointment, a cream, a lotion or a perfume. It can be made of glass or plastic. The tank 1 has a neck 11 forming an opening 10 communicating the interior of the tank with the outside. The neck 1 has an inner wall 1 delimiting the opening 10 of the neck, an upper end 13 and an outer wall 15. A hooking flange 16 is formed at the outer wall 15: this flange will be used for the fixation of the collar 2. The neck 11 also forms an inlet chamfer 14 which connects the upper end 13 to the inner wall 12. This chamfer 14 facilitates the mounting of the base on the neck 11, but still fulfills another function , as will be seen below. Below the flange 16, the neck 11 forms a narrowing before widening again forming a shoulder 17. Then, the tank comprises a barrel 18, closed by a bottom 19. The outer wall of the barrel 18 may for example be cylindrical circular. The capacity of the tank is generally of the order of a few milliliters.

Le bouchon, comme susmentionné, comporte deux éléments constitutifs, à savoir, l'embase de fixation 2 et l'organe d'obturation 3.The cap, as mentioned above, comprises two constituent elements, namely, the fixing base 2 and the shutter member 3.

L'embase de fixation 2 comprend un plateau radial 20, une jupe d'étanchéité 21 et une bague 22 de fixation.The fixing base 2 comprises a radial plate 20, a sealing skirt 21 and a fixing ring 22.

Le plateau radial 20 forme une surface supérieure, avantageusement circulaire et plane.The radial plate 20 forms an upper surface, advantageously circular and flat.

La jupe d'étanchéité 21 s'étend axialement vers le bas à partir du plateau radial 20.The sealing skirt 21 extends axially downwards from the radial plate 20.

La bague 22 s'étend axialement à partir de la périphérie externe du plateau radial 20 de façon concentrique à la jupe d'étanchéité 21 et comporte une extrémité inférieure pourvue d'un profil d'encliquetage 220, qui fait saillie vers l'intérieur.The ring 22 extends axially from the outer periphery of the radial plate 20 concentrically to the sealing skirt 21 and has a lower end provided with a detent profile 220, which projects inwards.

Ainsi, lorsque l'embase 2 est montée sur le col 40 du réservoir 4, la bague 22 est en contact de la paroi externe 15 et le profil d'encliquetage 220 est alors engagé sous le rebord 16. Avantageusement, la bague 22 s'étend dans l'alignement du fût 18, de manière à conférer avantageusement un aspect général tubulaire. Le plateau radial 20 est disposé avantageusement de façon à venir reposer sur l'extrémité supérieure 13 du col. La jupe d'étanchéité 21 vient quant à elle se loger dans l'ouverture du col, avantageusement en contact étanche avec la paroi interne 12 de sorte à éviter toute possibilité de fuite entre le col et l'embase.Thus, when the base 2 is mounted on the neck 40 of the reservoir 4, the ring 22 is in contact with the outer wall 15 and the snap profile 220 is then engaged under the flange 16. Advantageously, the ring 22 is extends in alignment with the barrel 18, so as to advantageously confer a tubular general appearance. The radial plate 20 is advantageously arranged so as to rest on the upper end 13 of the neck. The sealing skirt 21 is housed in the opening of the neck, preferably in sealing contact with the inner wall 12 so as to avoid any possibility of leakage between the neck and the base.

Selon l'invention, l'embase de fixation 2 comprend en outre des moyens d'essorage 25 qui sont réalisés de manière monobloc avec le restant de l'embase. En d'autres termes, l'embase de fixation 2 est une pièce de matière plastique injectée moulée qui forme de manière monobloc le plateau 20, la jupe 21, la bague 22 ainsi que les moyens d'essorage 25. Ces moyens d'essorage 25 sont situés, dans l'exemple de réalisation non limitatif de l'invention, dans le prolongement de la jupe 21 : plus précisément, la jupe 21 comprend une extrémité inférieure 211 à laquelle se raccordent de manière monobloc les moyens d'essorage 25. On peut également considérer que les moyens d'essorage 25 font partie intégrante de la jupe 21, qui comprend une partie supérieure destinée à assurer l'étanchéité avec la paroi interne 12 du col et une partie inférieure formant les moyens d'essorage 25. En variante, il est également possible de raccorder directement les moyens d'essorage 25 au plateau 20 sans former de jupe d'étanchéité 21. Il est également possible de raccorder les moyens d'essorage 25 au plateau 20 par une section intermédiaire qui ne remplit pas forcément la fonction de la jupe d'étanchéité 21. La fonction et l'utilisation des moyens d'essorage 25 seront décrites ci-après.According to the invention, the fixing base 2 further comprises wiper means 25 which are made integrally with the rest of the base. In other words, the fixing base 2 is a piece of molded injected plastic which forms in one piece the plate 20, the skirt 21, the ring 22 and the wiper means 25. These spinning means 25 are located, in the non-limiting embodiment of the invention, in the extension of the skirt 21: more precisely, the skirt 21 comprises a lower end 211 to which the dewatering means 25 are connected in one-piece fashion. It can also be considered that the dewatering means 25 are an integral part of the skirt 21, which comprises an upper part intended to seal with the inner wall 12 of the neck and a lower part forming the draining means 25. Alternatively, it is also possible to directly connect the dewatering means 25 to the tray 20 without forming a sealing skirt 21. It is also possible to connect the dewatering means 25 to the tray 20 by an intermedia section This function does not necessarily fulfill the function of the sealing skirt 21. The function and use of the dewatering means 25 will be described hereinafter.

Les moyens d'essorage 25 comprennent, dans ce mode de réalisation non limitatif, plusieurs pattes 26 qui sont reliées à l'extrémité inférieure 211 de la jupe 21. Ces pattes 26 sont séparées par des fentes 27 de forme longitudinale qui s'étendent initialement axialement. Les fentes 27 sont ouvertes vers le bas et s'étendent jusqu'au niveau de l'extrémité inférieure 211 de la jupe 21. Chaque patte 26 comprend une extrémité supérieure de jonction 261 raccordée à l'extrémité inférieure 211 de la jupe 21 et une extrémité inférieure libre 262. Chaque patte comprend en outre, à proximité de l'extrémité supérieure de jonction 261, un profil de came 263 qui fait saillie radialement vers l'extérieur. Ce profil de came 263 est situé sur la face externe de la patte 26, alors que sa face interne peut être cylindrique sans former de profil particulier.The spinning means 25 comprise, in this nonlimiting embodiment, several tabs 26 which are connected to the lower end 211 of the skirt 21. These tabs 26 are separated by slots 27 of longitudinal shape which extend initially. axially. The slots 27 are open downwards and extend to the level of the lower end 211 of the skirt 21. Each lug 26 comprises an upper end of junction 261 connected to the lower end 211 of the skirt 21 and a free bottom end 262. Each tab further comprises, near the upper end of junction 261, a cam profile 263 which projects radially outwardly. This cam profile 263 is located on the outer face of the tab 26, while its inner face may be cylindrical without forming a particular profile.

Selon une caractéristique intéressante de l'invention, les pattes 26, qui constituent toutes ensembles les moyens d'essorage 25, sont déplaçables radialement vers l'intérieur par pivotement autour de leurs extrémités de jonction 261. Les pattes 26 sont ainsi déplaçables ou mobiles entre une position initiale avant montage sur le col représenté sur les figures 1 et 2, et une position finale après montage sur le col représenté sur les figures 5 à 8. On peut facilement remarquer que la position finale après montage sur le col est obtenue par pivotement vers l'intérieur des pattes 26 autour de leurs extrémités supérieures 261. Les pattes 26, bien que déplacées par pivotement vers l'intérieur, restent sensiblement rigides ou indéformées hormis au niveau de la jonction entre leurs extrémités supérieures 261 et l'extrémité inférieure 211 de la jupe 21. Il n'est cependant pas exclu de prévoir des moyens d'essorage qui sont partiellement ou localement déformables. Toutefois, dans la forme de réalisation préférée de l'invention, les pattes 26 sont sensiblement indéformables et sont donc déplacées sans subir de déformation notable entre la position initiale et la position finale. Le déplacement entre ces deux positions est généré par la mise en contact du profil de came 263 avec la paroi interne 12 du col 11.According to an advantageous characteristic of the invention, the tabs 26, which together constitute the dewatering means 25, are movable radially inwards by pivoting about their joining ends 261. The tabs 26 are thus movable or movable between an initial position before mounting on the neck represented on the Figures 1 and 2 , and a final position after mounting on the neck shown on the Figures 5 to 8 . It can easily be seen that the final position after mounting on the neck is obtained by pivoting the lugs 26 about their upper ends 261 inwardly. The lugs 26, although displaced by pivoting inwards, remain substantially rigid or indistinct except at the junction between their upper ends 261 and the lower end 211 of the skirt 21. However, it is not excluded to provide dewatering means which are partially or locally deformable. However, in the preferred embodiment of the invention, the tabs 26 are substantially indeformable and are therefore displaced without undergoing significant deformation between the initial position and the final position. The displacement between these two positions is generated by contacting the cam profile 263 with the inner wall 12 of the neck 11.

En position initiale avant montage, le diamètre externe des moyens d'essorage 25 au niveau des profils de came 263 des pattes 26 est supérieur au diamètre interne du col au niveau de la paroi interne 12. Intérieurement, les moyens d'essorage sont de forme sensiblement cylindrique. L'engagement des moyens d'essorage 25 à l'intérieur du col 11 a pour effet de mettre en contact les profils de came 263 avec la paroi interne 12. Tout d'abord, les extrémités inférieures 262 des pattes sont engagées à l'intérieur du col 11 : cet engagement est facilité par le chanfrein d'entrée 14 qui évite tout risque de butée franche sur l'extrémité supérieure 13 du col. Etant donné que les pattes s'évasent vers l'extérieur à partir des extrémités inférieures 262 jusqu'au niveau du profil de came 263, elles vont obligatoirement venir en contact avec la paroi interne 12 et/ou avec le chanfrein d'entrée 14. Sur la figure 2, on peut clairement remarquer que les profils de came 263 ne sont pas encore engagés à l'intérieur de la paroi interne 12. Ils sont à ce stade situés juste au-dessus ou à hauteur de l'extrémité supérieure 13. Le contact entre les moyens d'essorage 25 et le col 11 n'a pas encore eu lieu. De même, la bague externe 22 n'est pas encore venue en contact avec le col 11. En continuant à engager l'embase de fixation 2 dans et autour du col 11, la bague 22 s'engage autour de la paroi externe 15 du col en se déformant radialement vers l'extérieur et les moyens d'essorage 25 sont situés, avec leur profil de came 263, au niveau de la paroi interne 12. Ceci est représenté sur la figure 4. Etant donné que les profils 263 définissent un diamètre supérieur à celui de la paroi interne 12, les pattes 26 sont contraintes de pivoter vers l'intérieur. Etant donné que les profils de came 263 sont situés à proximité des extrémités supérieures de jonction 261, le pivotement est accentué par un effet de levier, ce qui amène les extrémités inférieures libres 262 à se déplacer rapidement radialement vers l'intérieur en se rapprochant les unes des autres.In initial position before assembly, the outer diameter of the dewatering means 25 at the cam profiles 263 of the tabs 26 is greater at the internal diameter of the neck at the inner wall 12. Internally, the dewatering means are of substantially cylindrical shape. The engagement of the dewatering means 25 within the neck 11 has the effect of bringing the cam profiles 263 into contact with the inner wall 12. First, the lower ends 262 of the legs are engaged with the inside the neck 11: this commitment is facilitated by the entry chamfer 14 which avoids any risk of frank stop on the upper end 13 of the neck. Since the tabs flare outwardly from the lower ends 262 to the level of the cam profile 263, they will necessarily come into contact with the inner wall 12 and / or with the input chamfer 14. On the figure 2 it can clearly be seen that the cam profiles 263 are not yet engaged inside the inner wall 12. They are at this point situated just above or at the height of the upper end 13. The contact between the drying means 25 and the neck 11 has not yet occurred. Similarly, the outer ring 22 has not yet come into contact with the neck 11. By continuing to engage the fixing base 2 in and around the neck 11, the ring 22 engages around the outer wall 15 of the collar deforming radially outwardly and the wiper means 25 are located, with their cam profile 263, at the inner wall 12. This is shown in FIG. figure 4 . Since the profiles 263 define a diameter greater than that of the inner wall 12, the tabs 26 are forced to pivot inwards. Since the cam profiles 263 are located near the upper joint ends 261, the pivoting is accentuated by a leverage effect, causing the free lower ends 262 to move rapidly radially inwardly toward each other. each other.

En continuant à engager l'embase 2 sur le col 11, on parvient jusqu'à la position finale de montage représentée sur les figures 5 à 8. Le profil d'encliquetage 220 de la bague 22 est alors en prise en dessous du rebord 16 du col, et la jupe 21 est en contact étanche avec la paroi interne 12 du col. D'autre part, le plateau 20 est en butée sur l'extrémité supérieure 13 du col. Une fixation stable et étanche de l'embase 2 sur le col 11 est ainsi garantie. Les moyens d'essorage 25 sont dans leur position finale de fonctionnement. Les pattes 26 sont pivotées au maximum radialement vers l'intérieur sous l'effet de came généré entre les profils 263 et la paroi interne 12. Les profils de came 263 sont situés sensiblement à proximité de l'extrémité inférieure du col à hauteur de l'épaulement 17. Les extrémités inférieures libres 262 des pattes définissent toutes ensemble une couronne d'essorage 260. Les extrémités inférieures 262 sont avantageusement en contact les unes des autres pour former une couronne continue. En variante, il est possible que des interstices restent entre les extrémités libres 262, de sorte que la couronne d'essorage 260 est discontinue. On peut également dire que les fentes 27 qui séparent les pattes 26 sont resserrées ou fermées au niveau des extrémités inférieures 262, alors qu'au niveau des extrémités supérieures 261, la largeur des fentes est restée inchangée. Ainsi, entre la position initiale et la position finale, les fentes passent d'une forme sensiblement rectangulaire à une forme sensiblement triangulaire. On se référera ci-après aux figures 7 et 8 pour décrire le fonctionnement des moyens d'essorage.Continuing to engage the base 2 on the neck 11, it reaches the final assembly position shown on the Figures 5 to 8 . The snap profile 220 of the ring 22 is then engaged below the flange 16 of the neck, and the skirt 21 is in sealing contact with the inner wall 12 of the neck. On the other hand, the plate 20 abuts on the upper end 13 of the neck. A stable and waterproof attachment of the base 2 on the neck 11 is thus guarantee. The dewatering means 25 are in their final operating position. The tabs 26 are pivoted at the maximum radially inwards under the camming effect generated between the profiles 263 and the inner wall 12. The cam profiles 263 are located substantially close to the lower end of the neck at a height of 1 cm. The lower free ends 262 of the tabs all together define a wringing ring 260. The lower ends 262 are advantageously in contact with one another to form a continuous ring. Alternatively, it is possible that gaps remain between the free ends 262, so that the spin ring 260 is discontinuous. It can also be said that the slots 27 which separate the tabs 26 are tightened or closed at the lower ends 262, while at the upper ends 261, the width of the slots has remained unchanged. Thus, between the initial position and the final position, the slots change from a substantially rectangular shape to a substantially triangular shape. Reference will be made below to Figures 7 and 8 to describe the operation of the dewatering means.

L'organe d'obturation 3, réalisé de préférence en matière plastique injecté moulée, comprend un élément de préhension 30 et un élément de prélèvement et/ou d'application de produit fluide 31.The closure member 3, preferably made of molded injected plastic material, comprises a gripping element 30 and a sampling and / or fluid application member 31.

L'élément de préhension 30, destiné à être saisi par un utilisateur lors d'une application de produit fluide, peut présenter toutes formes appropriées. Selon un mode de réalisation préféré, l'élément de préhension 30 comporte deux faces opposées présentant une forme incurvée et plus particulièrement concave. Cette forme de réalisation est particulièrement avantageuse, facilitant la prise en main de l'organe d'obturation 3 et son retrait du réservoir 1.The gripping element 30, intended to be grasped by a user during a fluid application, may have all appropriate shapes. According to a preferred embodiment, the gripping element 30 has two opposite faces having a curved shape and more particularly concave. This embodiment is particularly advantageous, facilitating the grip of the shutter member 3 and its removal from the tank 1.

L'élément de prélèvement et/ou d'application 31 a pour fonction de permettre le prélèvement d'une quantité donnée de produit fluide. L'élément 31 présente une configuration générale allongée. Il comprend une tige 314 reliée à son extrémité supérieure à l'élément de préhension 30 et définissant à son extrémité inférieure une section de prélèvement/application 315 qui peut être réalisée avec une matière absorbante. Cette section 315 peut se présenter sous la forme d'une brosse ou d'un tampon cylindrique, don le diamètre externe est avantageusement supérieur à celui de la tige 314.The purpose of the sampling and / or application member 31 is to allow the sampling of a given quantity of fluid product. Element 31 has an elongated overall configuration. It comprises a rod 314 connected at its upper end to the gripping element 30 and defining at its lower end a sample / application section 315 which can be made with an absorbent material. This section 315 may be in the form of a brush or a cylindrical pad, the outer diameter is advantageously greater than that of the rod 314.

L'élément de prélèvement 31 a également pour fonction de faciliter la remise en place de l'organe d'obturation sur l'embase. L'élément 31 comporte avantageusement une surface de jonction 310, un cordon d'encliquetage 311 et une surface d'étanchéité 312. La surface de jonction 310 est une surface cylindrique circulaire s'étendant sur le pourtour de l'élément 31. Le cordon d'encliquetage 311 forme un bourrelet annulaire faisant saillie radialement à partir de l'élément 31. La surface d'étanchéité 312 correspond quant à elle également à une surface cylindrique circulaire s'étendant sur le pourtour de l'élément 31. Avantageusement, la surface de jonction 310 et la surface d'étanchéité 312 se situent de part et d'autre du cordon d'encliquetage 311. Dans le mode de réalisation représenté sur les différentes figures, la surface de jonction 310 est située en dessous du cordon d'encliquetage 311, alors que la surface d'étanchéité 312 est localisée entre le cordon d'encliquetage 312 et la base 302 de l'élément de préhension 30. La surface d'étanchéité 312 définit ainsi un logement d'encliquetage étanche entre le cordon 311 et la base 302.The sampling element 31 also serves to facilitate the refitting of the closure member on the base. The element 31 advantageously comprises a junction surface 310, a ratchet cord 311 and a sealing surface 312. The junction surface 310 is a circular cylindrical surface extending around the circumference of the element 31. The cord detent 311 forms an annular bead protruding radially from the element 31. The sealing surface 312 also corresponds to a circular cylindrical surface extending around the periphery of the element 31. Advantageously, the joining surface 310 and sealing surface 312 are located on either side of the ratchet bead 311. In the embodiment shown in the various figures, the joining surface 310 is located below the bead. snap 311, while the sealing surface 312 is located between the ratchet cord 312 and the base 302 of the gripping member 30. The sealing surface 312 thus defines a housing t tight snap between the cord 311 and the base 302.

L'élément de prélèvement 31 s'étend avantageusement de la base 302 à travers l'embase 2 jusque dans réservoir 1. Toutefois, il est à remarquer que la hauteur à laquelle s'étend la section 315 de l'élément 31 peut fortement varier. En effet, l'élément 31 peut avoir une tige 314 très courte ne dépassant pas la hauteur de l'embase 2, ou au contraire, une tige très longue venant quasiment au contact du fond 19 du réservoir 1.The sampling element 31 advantageously extends from the base 302 through the base 2 into tank 1. However, it should be noted that the height at which the section 315 of the element 31 extends can vary greatly. . Indeed, the element 31 may have a very short rod 314 not exceeding the height of the base 2, or on the contrary, a very long rod coming almost in contact with the bottom 19 of the tank 1.

L'organe d'obturation 3 est réalisé avantageusement de manière monobloc avec l'embase 2. Comme représenté sur les figures, l'organe d'obturation 3, en sortie de moule, est relié par un pont de matière annulaire 23 à l'embase 2. Plus précisément, le pont de matière 23 relie la surface de jonction 310 de l'élément 31 à un bord périphérique 200 formé par le plateau radial 20. Cette configuration a pour avantage de garantir une sécurité de premier usage, le produit contenu dans le réservoir ne pouvant être extrait avant rupture du pont de matière 23.The closure member 3 is advantageously made integrally with the base 2. As shown in the figures, the closure member 3, at the outlet of the mold, is connected by a bridge of annular material 23 to the base 2. More specifically, the material bridge 23 connects the junction surface 310 of the element 31 to a peripheral edge 200 formed by the radial plate 20. This configuration has the advantage of guaranteeing a safety of first use, the product contained in the tank can not be extracted before rupture of the material bridge 23.

Ce pont de matière, lors de la première utilisation, devra donc être rompu. Cette rupture est effectuée par un mouvement de traction, de poussée ou de rotation de l'organe d'obturation 3 par rapport à l'embase. Une telle rupture a alors pour effet d'aboutir à la création d'un orifice 24 délimité par le bord périphérique 200 du plateau radial 20. L'organe d'obturation 3 peut alors être librement extrait du réservoir 1 et de l'embase 2. Cette configuration donne ainsi lieu à un organe d'obturation 3 en position ouverte compatible avec le prélèvement et l'application de produit. Il est à noter que l'orifice 24 est avantageusement ménagé au centre du plateau radial 20 et que cet orifice présente toutes formes appropriées : circulaire, oblong, elliptique etc. La dimension de l'orifice 24 est avantageusement telle que du produit fluide sera retenu par capillarité au niveau de l'orifice si le distributeur est penché, voire retourné. Pour ce faire, l'orifice 24 présentera avantageusement un diamètre restreint de l'ordre de 2 à 6 mm et de préférence de l'ordre de 3 à 4 mm.This material bridge, during the first use, must be broken. This break is effected by a movement of traction, thrust or rotation of the closure member 3 relative to the base. Such a rupture then results in the creation of an orifice 24 delimited by the peripheral edge 200 of the radial plate 20. The shutter member 3 can then be freely extracted from the tank 1 and the base 2 This configuration thus gives rise to a shutter member 3 in the open position compatible with the sampling and the application of product. It should be noted that the orifice 24 is advantageously formed in the center of the radial plate 20 and that this orifice has all appropriate shapes: circular, oblong, elliptical, etc. The size of the orifice 24 is advantageously such that the fluid product will be retained by capillarity at the orifice if the dispenser is tilted, or even returned. To do this, the orifice 24 will advantageously have a restricted diameter of the order of 2 to 6 mm and preferably of the order of 3 to 4 mm.

Il est à noter que le bord périphérique 200 formant l'orifice 24 sert initialement de point d'attache pour le pont de matière cassante et ensuite de zone annulaire d'étanchéité en coopération la surface d'étanchéité 312 de l'organe d'obturation.It should be noted that the peripheral edge 200 forming the orifice 24 initially serves as a point of attachment for the bridge of brittle material and then of the annular sealing zone in cooperation with the sealing surface 312 of the closure member .

L'organe d'obturation peut être remis en place. L'organe d'obturation peut alors définir une position fermée de refermeture. Cette position permet à l'organe d'obturation 3 d'être fermement maintenu sur l'embase 2. Pour ce faire, un système d'encliquetage est prévu. Ce système d'encliquetage met en oeuvre une coopération entre le bord périphérique 200 de l'embase 2 et le cordon d'encliquetage 311 de l'élément 31. Cette coopération a lieu suite à une pression de l'organe d'obturation suffisamment forte pour que le bord périphérique 200 franchisse le cordon d'encliquetage 311. Une fois le cordon d'encliquetage 311 franchi, le bord périphérique 200 retenu par le cordon d'encliquetage 311 maintient l'organe d'obturation en position fermée de refermeture. Dans cette position, le bord périphérique 200 est alors en prise étanche avec la surface d'étanchéité 312 de l'élément 31 évitant ainsi toutes possibilités de fuite de produit entre l'élément 31 et l'embase 2.The closure member can be put back in place. The shutter member can then define a closed closed position. This position allows the closure member 3 to be firmly held on the base 2. To do this, a detent system is provided. This latching system implements a cooperation between the peripheral edge 200 of the base 2 and the ratchet cord 311 of the element 31. This cooperation takes place following a pressure of the shutter member sufficiently strong so that the peripheral edge 200 crosses the ratchet cord 311. Once the ratchet cord 311 has passed, the peripheral edge 200 retained by the ratchet cord 311 holds the closure member in the closed re-closing position. In this position, the peripheral edge 200 is then engaged sealing with the sealing surface 312 of the element 31 thus avoiding any possibility of product leakage between the element 31 and the base 2.

Enfin, lorsque l'utilisateur souhaitera repasser en position ouverte, une simple traction exercée sur l'organe d'obturation 3 permettra au bord périphérique 200 de passer le cordon d'encliquetage 311 et ainsi d'extraire l'élément 31.Finally, when the user wishes to return to the open position, a simple traction exerted on the shutter member 3 will allow the peripheral edge 200 to pass the ratchet cord 311 and thus extract the element 31.

Ainsi, l'embase de fixation 2 forme de manière monobloc les moyens d'essorage 25, et peut avantageusement être également formée de manière monobloc avec l'organe d'obturation. En position finale de montage, comme par exemple représentée sur la figure 6, la couronne d'essorage 260 formée par les extrémités inférieures libres 262 des pattes 26 s'étend autour de la tige 314 en créant un contact ou en laissant un petit interstice annulaire. Un contact léger sans frottement est avantageux, car il permet à la couronne d'essorage 260 de racler légèrement la tige 314 pour la nettoyer et la maintenir propre.Thus, the mounting base 2 integrally forms the draining means 25, and may advantageously also be integrally formed with the closure member. In final assembly position, as for example represented on the figure 6 , the wringing ring 260 formed by the free lower ends 262 of the tabs 26 extends around the rod 314 creating a contact or leaving a small annular gap. Light friction free contact is advantageous because it allows the wring ring 260 to gently scrape the rod 314 for cleaning and keeping it clean.

Lorsqu'un utilisateur veut se servir pour la première fois du dispositif applicateur de l'invention, il doit d'abord séparer l'organe d'obturation 3 de l'embase de fixation 2 en cassant le pont de matière 23. Ceci s'effectue par traction, torsion ou rotation. Ensuite, l'utilisateur peut extraire l'organe de prélèvement et d'application 31 du réservoir à travers l'embase 2. Cette extraction s'effectue en faisant d'abord coulisser la tige 314 à travers les moyens d'essorage 25. La couronne d'essorage 260 va ainsi coulisser avec frottement ou non le long de la tige 314 jusqu'au niveau de la section de prélèvement/application 315. Les figures 7 et 8 représentent le dispositif applicateur dans cette position. On peut voir et comprendre que la section de prélèvement/application 315 est située juste en dessous de la couronne d'essorage 260, et va être tirée à travers la couronne 260 dans le but de l'essorer partiellement pour ne laisser que la quantité de produit fluide nécessaire. Etant donné que la section 315 présente une section légèrement supérieure à celle de la tige 314, mais que sa consistance est molle, souple spongieuse et/ou déformable, la section 315 va se déformer au contact de la couronne d'essorage 260 pour en exprimer une partie du produit fluide qu'elle a prélevée dans le réservoir. Une fois l'organe d'obturation 3 entièrement retiré de l'embase 2, l'utilisateur peut appliquer le produit fluide prélevé par la section 315. Lorsque l'utilisateur a terminé l'application, il introduit à nouveau l'élément 31 dans le réservoir à travers l'embase 2. Cette introduction a pour effet de faire passer à nouveau la section 315 à travers la couronne d'essorage 260. Du produit fluide peut à nouveau être exprimé. Toutefois, il n'y a aucun risque que le produit fluide reste au niveau des moyens d'essorage 25, étant donné que les pattes 26 sont séparées par des fentes triangulaires 27. Ainsi, le produit fluide peut s'écouler hors des moyens d'essorage 25 à travers ces fentes.When a user wants to use for the first time the applicator device of the invention, it must first separate the closure member 3 of the attachment base 2 by breaking the material bridge 23. This is performs by pulling, twisting or rotating. Then, the user can extract the sampling and application member 31 from the reservoir through the base 2. This extraction is performed by first sliding the rod 314 through the wiper means 25. The wring ring 260 will thus slide with friction or not along the rod 314 to the level of the sampling section / application 315. The Figures 7 and 8 represent the applicator device in this position. It can be seen and understood that the sampling / application section 315 is located just below the spin ring 260, and will be pulled through the ring 260 for the purpose of partially wringing it out to leave only the amount of fluid product needed. Since the section 315 has a section slightly greater than that of the rod 314, but its consistency is soft, flexible spongy and / or deformable, the section 315 will deform in contact with the wringer 260 to express a part of the fluid product that she took from the tank. Once the shutter member 3 is completely removed from the base 2, the user can apply the fluid collected by the section 315. When the user has finished the application, he introduces the element 31 again in the reservoir through the base 2. This introduction has the effect of passing the section 315 again through the wringing ring 260. The fluid can be again expressed. However, there is no risk that the fluid remains at the level of the dewatering means 25, since the tabs 26 are separated by triangular slots 27. Thus, the fluid can flow out of the means of drying. spin through these slots.

Grâce à l'invention, des moyens d'essorage font partie intégrante de la pièce qui vient se fixer sur le réservoir, et avantageusement, cette pièce de fixation est réalisée de manière monobloc avec l'organe d'obturation qui forme l'élément de prélèvement et d'application qui va être essoré à travers les moyens d'essorage.Thanks to the invention, dewatering means are an integral part of the part which is fixed to the reservoir, and advantageously, this fastener is made integrally with the closure member which forms the element of sampling and application that will be wrung out through the spinning means.
