Description

Organe de fixation pour fixer une pompe ou une valve sur un réservoir. Fixing device to fix a pump or a valve on a tank.
La présente invention concerne un organe de fixation pour fixer un organe de distribution, tel que par exemple une pompe ou une valve, sur un réservoir destiné à contenir un produit fluide liquide, ou même pulvérulent. Ce genre d'organe de fixation est fréquemment utilisé dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie pour fixer des pompes ou des valves sur des récipients de produit fluide.The present invention relates to a fixing member for fixing a dispensing member, such as for example a pump or a valve, to a reservoir intended to contain a liquid or even powdery fluid product. This type of fixing member is frequently used in the field of perfumery, cosmetics or even pharmacy to fix pumps or valves on containers of fluid product.
De manière classique, un organe de fixation comprend une bague de fixation, généralement en matière plastique, associée à une frette d'habillage qui peut être réalisée en métal ou en matière plastique. La frette d'habillage est montée autour de la bague de manière à la masquer au moins partiellement pour lui conférer avantageusement un aspect esthétique attrayant. De manière classique, la frette d'habillage est engagée axialement en force autour de la bague de fixation, et ce seul contact serrant par frottement suffit en principe à la fixation de la frette sur la bague. Cependant, il arrive fréquemment que la frette tourne autour de la bague ou s'en dégage axialement en exerçant une force très limitée.Conventionally, a fixing member comprises a fixing ring, generally made of plastic, associated with a covering band which can be made of metal or plastic. The covering band is mounted around the ring so as to at least partially mask it to advantageously give it an attractive aesthetic appearance. Conventionally, the covering hoop is axially engaged in force around the fixing ring, and this single contact tightening by friction is sufficient in principle for fixing the hoop on the ring. However, it frequently happens that the hoop turns around the ring or emerges from it axially by exerting a very limited force.
Le document FR-2 799 185 apporte une solution partielle à ce problème de la fixation solide de la frette sur la bague. En effet, il est prévu dans ce document de sertir la frette d'habillage à l'intérieur d'une douille formée par la bague. Le sertissage est sensée assurer à la fois un blocage en translation axiale et un blocage en rotation. Toutefois, il arrive tout de même que la frette puisse tourner sur la bague, même avec ce sertissage interne. En effet, le sertissage est plus spécialement adapté à un blocage en translation et ne met pas en œuvre des moyens spécifiques, hormis un contact serrant, pour assurer le blocage en rotation.Document FR-2 799 185 provides a partial solution to this problem of the solid fixing of the hoop on the ring. Indeed, it is provided in this document to crimp the cover band inside a socket formed by the ring. The crimping is supposed to ensure both locking in axial translation and locking in rotation. However, it still happens that the hoop can rotate on the ring, even with this internal crimping. In fact, the crimping is more especially adapted to a blocking in translation and does not use specific means, apart from a tight contact, to ensure the blocking in rotation.
Le document FR-2 779 419, sur lequel le préambule de la revendication principale est basé, décrit une pompe montée dans une bague qui est insérée en force dans un col de réservoir. La bague forme extérieurement une gorge destinée à venir en prise avec des dents formées à l'intérieur d'un capot. Les dents assurent un verrouillage à la fois en rotation et en translation. Les dents se présentent sous la forme de plots rectangulaires qui font saillie à partir de la paroi interne du capot. Toutefois, il n'est pas clairement mentionné comment les dents sont maintenues dans la gorge. Le but de la présente invention est de remédier aux problèmes susmentionnés de fixation de la frette en définissant un organe de fixation dont la frette est fixée de manière parfaitement stable et solide sur la bague.Document FR-2 779 419, on which the preamble of the main claim is based, describes a pump mounted in a ring which is force-fitted into a tank neck. The ring externally forms a groove intended to come into engagement with teeth formed inside a cover. The teeth provide locking both in rotation and in translation. The teeth are in the form of rectangular studs which protrude from the internal wall of the cover. However, it is not clearly mentioned how the teeth are held in the throat. The object of the present invention is to remedy the aforementioned problems of fixing the hoop by defining a fixing member, the hoop of which is fixed in a perfectly stable and solid manner to the ring.
Pour atteindre ce but, la présente invention propose un organe de fixation pour fixer un organe de distribution, tel qu'une pompe ou une valve, sur un réservoir de produit fluide, ledit organe de fixation comprenant une bague de fixation et une frette d'habillage, la bague de fixation comprenant des moyens de réception pour recevoir l'organe de distribution et des moyens de fixation sur le réservoir, la frette d'habillage étant montée par engagement axial autour de la bague de manière à la masquer au moins partiellement, la frette comprenant des moyens d'accrochage coopérant avec des moyens de retenue formés par la bague, lesdits moyens d'accrochage comprennent des moyens de blocage en rotation pour empêcher la frette de tourner autour de la bague et des moyens de blocage en translation axiale pour empêcher la frette de se désengager axialement de la bague, les moyens de retenue formés par la bague comprenant au moins un logement de retenue accessible par engagement axial, lesdits moyens de blocage en rotation et en translation coopérant avec le logement de retenue, caractérisé en ce que les moyens de blocage en translation comprennent au moins un profil d'harponnage adapté à mordre dans le logement.To achieve this object, the present invention provides a fixing member for fixing a dispensing member, such as a pump or a valve, to a fluid reservoir, said fixing member comprising a fixing ring and a hoop of covering, the fixing ring comprising receiving means for receiving the dispensing member and fixing means on the reservoir, the covering hoop being mounted by axial engagement around the ring so as to mask it at least partially, the hoop comprising hooking means cooperating with retaining means formed by the ring, said hooking means comprise means for locking in rotation to prevent the hoop from rotating around the ring and means for locking in axial translation for prevent the hoop from disengaging axially from the ring, the retaining means formed by the ring comprising at least one retaining housing accessible by axial engagement , said means for locking in rotation and in translation cooperating with the retaining housing, characterized in that the means for locking in translation comprise at least one harpooning profile adapted to bite into the housing.
Avantageusement, les moyens de blocage en rotation comprennent au moins un élément d'accrochage engagé axialement dans le logement de retenue.Advantageously, the rotation locking means comprise at least one latching element engaged axially in the retaining housing.
Avantageusement, le profil d'harponnage est formé par l'élément d'accrochage. Ainsi, les moyens de blocage en translation et les moyens de blocage en rotation sont formés par un élément d'accrochage unique qui coopère avec un logement de retenue unique. Bien entendu, on peut prévoir plusieurs éléments d'accrochage coopérant avec plusieurs logements de retenue respectifs.Advantageously, the harpooning profile is formed by the hooking element. Thus, the means for locking in translation and the means for locking in rotation are formed by a single hooking element which cooperates with a single retaining housing. Of course, one can provide several hooking elements cooperating with several respective retaining housings.
Toutefois, un seul élément d'accrochage incorpore à la fois des moyens de blocage en rotation et des moyens de blocage en translation axiale. Le profil d'harponnage permet un blocage translatif efficace, contrairement aux dents du document précité.However, only one hooking element incorporates both means of locking in rotation and locking means in axial translation. The harpooning profile allows effective translational blocking, unlike the teeth of the aforementioned document.
Selon une forme de réalisation pratique, la bague comprend une douille définissant une extrémité libre, la douille formant ledit au moins un logement de retenue, la frette comprenant une extrémité inférieure libre et une extrémité supérieure formant un rabat rentrant, l'élément d'accrochage étant relié audit rabat en pointant sensiblement vers rextrémité inférieure de la frette, de sorte que l'élément d'accrochage pénètre dans le logement de retenue lors du montage de la frette par engagement axial sur la bague. Avantageusement, l'élément d'accrochage atteint une position finale d'accrochage dans son logement de retenue lorsque le rabat rentrant vient en butée sur extrémité libre de la douille.According to a practical embodiment, the ring comprises a sleeve defining a free end, the sleeve forming said at least one retaining housing, the hoop comprising a free lower end and an upper end forming a re-entrant flap, the hooking element being connected to said flap pointing substantially towards the lower end of the hoop, so that the hooking element penetrates into the retaining housing when the hoop is mounted by axial engagement on the ring. Advantageously, the hooking element reaches a final hooking position in its retaining housing when the re-entrant flap abuts on the free end of the sleeve.
Selon une caractéristique de l'invention, le logement de retenue est délimitée par deux parois longitudinales verticales opposées, l'élément d'accrochage étant en prise avec lesdites parois. Avantageusement, le profil d'harponnage est adapté à mordre dans lesdites parois.According to a characteristic of the invention, the retaining housing is delimited by two opposite vertical longitudinal walls, the fastening element being in engagement with said walls. Advantageously, the harpooning profile is adapted to bite into said walls.
La bague peut être en plastique et la frette en métal ou en un plastique plus dur que celui de la bague.The ring can be made of plastic and the hoop made of metal or a harder plastic than that of the ring.
L'invention sera maintenant 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 now be described more fully with reference to the accompanying drawings which give an embodiment of the invention by way of non-limiting example.
Sur les figures :In the figures:
- la figure 1 est une vue en coupe transversale verticale à travers un organe de fixation de l'invention dans lequel est monté un organe de distribution, - la figure 2 est une vue en coupe transversale verticale à travers la frette d'habillage d'un organe de fixation selon l'invention, et- Figure 1 is a vertical cross-sectional view through a fixing member of the invention in which a dispensing member is mounted, - Figure 2 is a vertical cross-sectional view through the cover band of a fixing member according to the invention, and
- la figure 3 est une vue en coupe transversale verticale à travers une bague de fixation d'un organe de fixation selon l'invention.- Figure 3 is a vertical cross-sectional view through a fixing ring of a fixing member according to the invention.
L'organe de fixation représenté sur les figures est désigné dans son ensemble par la référence numérique 1 et comprend avantageusement deux éléments constitutifs, à savoir une bague de fixation 2 et une frette d'habillage 3. La frette d'habillage 3 est montée autour de la bague de fixation 2 et remplit une fonction esthétique, mais parfois également fonctionnelle de fixation.The fixing member shown in the figures is designated as a whole by the reference numeral 1 and advantageously comprises two constituent elements, namely a fixing ring 2 and a covering band 3. The covering band 3 is mounted around the fixing ring 2 and fulfills an aesthetic, but sometimes also functional, fixing function.
La bague de fixation 2 comprend des moyens de fixation aptes à coopérer avec un réservoir (non représenté) ou plus précisément une ouverture du réservoir qui peut par exemple se présenter sous la forme d'un col saillant. La bague de fixation 2 est plus particulièrement adaptée à coopérer avec la paroi externe de l'ouverture du réservoir qui est avantageusement réalisée avec un ou plusieurs profils de préhension. Ces profils de préhension peuvent par exemple se présenter sous la forme d'un filetage externe ou encore sous la forme d'un rebord épaissi formant un épaulement inférieur de préhension. Dans le cas présent, la bague de fixation comprend une jupe de fixation 21 qui est pourvue intérieurement d'un filetage interne 211 destiné à coopérer avec un filetage correspondant formé sur la paroi externe d'un col de réservoir ou de récipient. Sans changer l'esprit de l'invention, la jupe de fixation 21 peut également être pourvue de têtes de préhension ou d'encliquetage destinées à coopérer avec un profil d'accrochage correspondant formé sur la paroi externe d'un col de récipient. Plus généralement, la bague de fixation comprend une jupe de fixation 21 permettant d'assurer une fixation stable de la bague de fixation sur un récipient. La bague de fixation 2 comprend également des moyens de réception pour recevoir fixement un organe de distribution. L'organe de distribution 4, qui est représenté très schématiquement sur la figure 1, peut être une pompe ou une valve. Sa structure interne n'a aucune importance pour la présente invention ; c'est pourquoi elle n'est même pas représentée. L'organe de distribution 4 comprend en général un corps 40 à l'intérieur duquel une soupape 42 est déplaçable axialement. Le corps 40 peut former ou être pourvu d'une collerette de fixation 41 destinée à coopérer avec les moyens de réception formés par la bague de fixation 2. Dans le cas présent, la bague de fixation forme un logement d'encliquetage 24 à l'intérieur duquel la collerette 41 de l'organe de distribution 4 est engagée en force et maintenue fixement. Pour améliorer la stabilité de l'organe de distribution 4 dans la bague de fixation 2, la bague forme ici en outre un manchon de maintien 23 à l'intérieur duquel l'organe de distribution 4 est en prise.The fixing ring 2 comprises fixing means able to cooperate with a reservoir (not shown) or more precisely an opening of the reservoir which may for example be in the form of a projecting neck. The fixing ring 2 is more particularly adapted to cooperate with the external wall of the opening of the reservoir which is advantageously produced with one or more gripping profiles. These gripping profiles may for example be in the form of an external thread or else in the form of a thickened rim forming a lower gripping shoulder. In the present case, the fixing ring comprises a fixing skirt 21 which is provided internally with an internal thread 211 intended to cooperate with a corresponding thread formed on the external wall of a tank or container neck. Without changing the spirit of the invention, the fixing skirt 21 can also be provided with gripping or latching heads intended to cooperate with a corresponding attachment profile formed on the external wall of a container neck. More generally, the fixing ring comprises a fixing skirt 21 making it possible to ensure a stable fixing of the fixing ring on a container. The fixing ring 2 also comprises receiving means for fixedly receiving a dispensing member. The dispensing member 4, which is shown very schematically in FIG. 1, can be a pump or a valve. Its internal structure is of no importance for the present invention; that is why it is not even represented. The dispensing member 4 generally comprises a body 40 inside which a valve 42 is axially displaceable. The body 40 may form or be provided with a fixing flange 41 intended to cooperate with the receiving means formed by the fixing ring 2. In the present case, the fixing ring forms a latching housing 24 at the inside of which the collar 41 of the dispensing member 4 is forcibly engaged and fixedly held. To improve the stability of the dispensing member 4 in the fixing ring 2, the ring here also forms a holding sleeve 23 inside which the dispensing member 4 is engaged.
D'autre part, la bague de fixation 2 forme une douille 22 qui peut avantageusement s'étendre dans le prolongement de la jupe de fixation 21. La jupe 21 peut s'étendre vers le bas alors que la douille 22 s'étend vers le haut pour se terminer par une extrémité supérieure libre 222. La douille 22 peut avoir le même diamètre que celui de la jupe 21 ou un diamètre différent. En se référant à la figure 3, on peut voir plus clairement que la douille 22 de la bague 2 forme un logement de retenue 225 qui est ouvert vers le haut. Ce logement de retenue 225 est ici délimité par deux parois 224 qui s'étendent sensiblement verticalement l'une en face de l'autre. L'écartement entre les deux parois détermine la largeur du logement. Cet écartement peut être constant, croissant ou décroissant à partir de son ouverture supérieure. Ces parois 224 sont au moins partiellement formées par deux brides verticales longitudinales 223 formées sur la paroi interne de la douille 22. Les parois 224 comprennent ainsi une composante verticale, mais également une composante radiale. De préférence, mais pas obligatoirement, la douille 22 forme une échancrure 222 au niveau du logement de retenue 225. On peut cependant imaginer une douille dépourvue d'une telle échancrure 222 de sorte que la douille est complète et continue sur toute sa périphérie au niveau de son extrémité supérieure 222. Dans ce cas, le logement de retenue 225 n'est formé qu'à l'intérieur de la douille par les parois 224 des deux brides 223. Sur les figures, on ne voit qu'un seul logement de retenue 225, mais on peut très bien prévoir plusieurs logement de retenue 225 répartis par exemple de manière équidistante sur la périphérie de la douille 22. La frette d'habillage 3 comprend ici un fut parfaitement cylindrique 31 présentant une extrémité inférieure 32 et une extrémité supérieure 33. Le diamètre interne du fût 31 est avantageusement égal ou très légèrement inférieur au diamètre externe maximal de la bague de fixation 2. Ainsi, le fût 31 de la frette 3 peut être engagé avec un contact de frottement serrant autour de la bague de fixation 2, pour réaliser une fixation primaire. La frette 3 forme au niveau de son extrémité supérieure 33 un rabat périphérique rentrant 34 qui peut avantageusement former un petit retour 341 orienté vers le bas sensiblement parallèlement et de manière concentrique au fût 31.On the other hand, the fixing ring 2 forms a bush 22 which can advantageously extend in the extension of the fixing skirt 21. The skirt 21 can extend downwards while the bush 22 extends towards the high to end with a free upper end 222. The socket 22 may have the same diameter as that of the skirt 21 or a different diameter. Referring to Figure 3, it can be seen more clearly that the sleeve 22 of the ring 2 forms a retaining housing 225 which is open upwards. This retaining housing 225 is here delimited by two walls 224 which extend substantially vertically one opposite the other. The distance between the two walls determines the width of the housing. This spacing can be constant, increasing or decreasing from its upper opening. These walls 224 are at least partially formed by two vertical longitudinal flanges 223 formed on the internal wall of the sleeve 22. The walls 224 thus comprise a vertical component, but also a radial component. Preferably, but not necessarily, the socket 22 forms a notch 222 at the level of the retaining housing 225. One can however imagine a socket devoid of such a notch 222 so that the socket is complete and continuous over its entire periphery at the level of its upper end 222. In this case, the retaining housing 225 is formed only inside the sleeve by the walls 224 of the two flanges 223. In the figures, we see only one housing retaining 225, but one can very well provide several retaining housing 225 distributed for example equidistantly on the periphery of the sleeve 22. The covering hoop 3 here comprises a perfectly cylindrical barrel 31 having a lower end 32 and an upper end 33. The internal diameter of the barrel 31 is advantageously equal to or very slightly less than the maximum external diameter of the fixing ring 2. Thus, the barrel 31 of the hoop 3 can be engaged with frictional contact tightening around the fastening ring 2 to realize a primary fixation. The hoop 3 forms at its upper end 33 a re-entrant peripheral flap 34 which can advantageously form a small return 341 oriented downwards substantially parallel and concentrically to the barrel 31.
Selon l'invention, la frette d'habillage 3 forme un élément d'accrochage 35 qui réalise à la fois un blocage en rotation et un blocage en translation axiale de la frette sur la bague. L'élément d'accrochage 35 est réalisé de manière monobloc pour la frette d'habillage. Toutefois, ces fonctions de blocage en rotation et de blocage en translation axiale pourraient être dissociées de manière à être assurées par deux éléments distincts, mais de préférence selon l'invention ces deux fonctions de blocage sont réalisées par un seul et même élément d'accrochage 35. Cet élément d'accrochage 35 s'étend dans le prolongement du retour 341 ou du rabat rentrant 34 en pointant vers le bas en direction de l'extrémité inférieure 32 de la frette. L'élément d'accrochage 35 se présente ici sous la forme d'une flèche formant un corps sensiblement droit 351 au bout duquel est formée une tête d'harponnage formant un ou deux profils d'harponnage 352. On peut bien entendu imaginer un élément d'accrochage formé avec uniquement un seul profil d'harponnage ou encore avec plus de deux profils d'harponnage. L'élément d'accrochage 35 s'étend sensiblement axialement, mais également tangentiellement.According to the invention, the covering hoop 3 forms a hooking element 35 which achieves both a locking in rotation and a locking in axial translation of the hoop on the ring. The hooking element 35 is produced in a single piece for the covering hoop. However, these functions of blocking in rotation and blocking in axial translation could be dissociated so as to be ensured by two distinct elements, but preferably according to the invention these two blocking functions are performed by a single and same hooking element. 35. This hooking element 35 extends in the extension of the return 341 or the re-entrant flap 34, pointing downwards in the direction of the lower end 32 of the hoop. The hooking element 35 is here in the form of an arrow forming a substantially straight body 351 at the end of which is formed a harpooning head forming one or two harpooning profiles 352. One can of course imagine an element hooking formed with only one harpoon profile or with more than two harpoon profiles. The hooking element 35 extends substantially axially, but also tangentially.
En se réfèrent simultanément aux figures 2 et 3, on comprendra aisément qu'en engageant axialement la frette d'habillage 3 sur la bague de fixation 2, l'élément d'accrochage 35 va s'engager axialement à l'intérieur du logement de retenue 225 formé par la douille 22 de la bague de fixation 2. Bien entendu, il faut préalablement orienter correctement la frette d'habillage 3 pour aligner axialement l'élément d'accrochage 35 avec le logement de retenue 225. L'élément d'accrochage 35 peut ainsi pénétrer dans le logement 225 lors du montage de la frette sur la bague sans opération additionnelle. L'élément d'accrochage 35 va venir se positionner entre les deux parois 224 du logement 225, ce qui assure déjà un blocage en rotation de la frette sur la bague. Le corps 351 de l'élément d'accrochage 35 peut présenter une largeur inférieure ou égale à la distance séparant les deux parois 224 du logement 225. Cependant, la largeur de la tête au niveau des profils d'accrochage 352 est supérieure à la distance séparant les deux parois 224 du logement 225. De ce fait, l'engagement de l'élément d'accrochage 35 dans le logement 225 a pour effet de faire mordre les profils d'accrochage 352 dans les parois 224 du logement 225. Du fait de leur configuration à la manière d'un harpon, les profils d'harponnage 352 peuvent être insérés avec une force de pression limitée à l'intérieur du logement 225, alors que leur retrait est rendu impossible à la manière d'un harpon classique. Ainsi, un blocage en translation axiale est assuré.Referring simultaneously to Figures 2 and 3, it will be readily understood that by axially engaging the covering hoop 3 on the fixing ring 2, the hooking element 35 will engage axially inside the housing of retaining 225 formed by the sleeve 22 of the fixing ring 2. Of course, it is necessary beforehand to correctly orient the covering hoop 3 to axially align the hooking element 35 with the retaining housing 225. The attachment 35 can thus enter the housing 225 during mounting of the hoop on the ring without additional operation. The hooking element 35 will be positioned between the two walls 224 of the housing 225, which already ensures the rotation of the hoop on the ring. The body 351 of the attachment element 35 may have a width less than or equal to the distance separating the two walls 224 of the housing 225. However, the width of the head at the level of the attachment profiles 352 is greater than the distance separating the two walls 224 of the housing 225. Therefore, the engagement of the hooking element 35 in the housing 225 has the effect of biting the hooking profiles 352 in the walls 224 of the housing 225. As a result of their configuration like a harpoon, the harpoon profiles 352 can be inserted with a limited pressing force inside the housing 225, while their removal is made impossible like a conventional harpoon. Thus, a blockage in axial translation is ensured.
Il faut noter que les fonctions de blocage en rotation et en translation axiale sont ici assurées par un seul élément d'accrochage coopérant avec un seul logement de retenue. On peut bien entendu prévoir plusieurs éléments d'accrochage 35 répartis avantageusement de manière régulière sur le pourtour du rabat rentrant 34 de la frette 3. La bague de fixation 2 peut être réalisée en un matériau plastique. Quant à la frette d'habillage 3, elle peut également être réalisée en un matériau plastique, mais son élément d'accrochage 35 doit être réalisé en un matériau plastique plus dur pour pouvoir remplir sa fonction d'harponnage. De préférence, la frette d'habillage 3 est réalisée en métal.It should be noted that the functions of locking in rotation and in axial translation are here provided by a single hooking element cooperating with a single retaining housing. It is of course possible to provide several hooking elements 35 advantageously distributed regularly on the periphery of the re-entrant flap 34 of the hoop 3. The fixing ring 2 can be made of a plastic material. As for the covering hoop 3, it can also be made of a plastic material, but its hooking element 35 must be made of a harder plastic material to be able to fulfill its harpooning function. Preferably, the covering hoop 3 is made of metal.
Bien que le fût 31 de la frette 3 soit ici en contact serrant avec la bague 2, on peut très bien imaginer une forme de réalisation dans laquelle le fût 31 n'est pas en contact serrant avec la bague de fixation 2. La fixation de la frette sur la bague est alors assurée entièrement par l'engagement du ou des éléments d'accrochage 35 dans un ou plusieurs logements de retenue respectifs. Le ou les éléments d'accrochage sont ici réalisés au niveau du rabat rentrant de la frette. Cependant, on peut les localiser à un autre endroit de la frette, par exemple en bas de la frette. Although the barrel 31 of the hoop 3 is here in tight contact with the ring 2, one can very well imagine an embodiment in which the barrel 31 is not in tight contact with the fixing ring 2. The fixing of the hoop on the ring is then entirely ensured by the engagement of the hooking element or elements 35 in one or more respective retaining housings. The attachment element (s) are here produced at the level of the flap returning from the hoop. However, they can be located elsewhere in the hoop, for example at the bottom of the hoop.
