Description

Dispositif de fixation et distributeur comprenant un tel dispositif de fixation. Fixing device and dispenser comprising such a fixing device.
La présente invention concerne un dispositif de fixation pour fixer un organe de distribution sur un col de réservoir, ainsi qu'un distributeur comprenant un réservoir, un organe de distribution et un dispositif de fixation de l'invention.The present invention relates to a fixing device for fixing a dispensing member to a tank neck, as well as a dispenser comprising a reservoir, a dispensing member and a fixing device of the invention.
Il est en effet fréquent dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie d'utiliser des dispositifs de fixation pour fixer un organe de distribution tel qu'une pompe ou une valve dans une ouverture de réservoir qui se présente souvent sous la forme d'un col. Ce col comprend généralement une paroi interne, une paroi externe ainsi qu'une paroi d'extrémité supérieure reliant la paroi interne à la paroi externe. Le dispositif de fixation comprend en général des moyens de réception adaptés à recevoir fixement le corps de la pompe ou de la valve. De manière classique, le corps de pompe ou de valve est engagé en force dans un logement d'encliquetage formé par les moyens de réception. D'autre part, le dispositif de fixation comprend des moyens de fixation aptes à venir en prise avec le col ou l'ouverture du réservoir pour s'y maintenir fixement. Il existe diverses techniques permettant de fixer le dispositif de fixation sur ou dans le col ou l'ouverture de réservoir. Ces moyens de fixation peuvent par exemple se présenter sous la forme d'une jupe fendue ou continue qui vient en prise avec la paroi externe du col. La jupe fendue ou continue peut par exemple être formée avec des têtes d'encliquetage internes qui viennent se loger en dessous d'un épaulement formé par la paroi externe du col. Une autre technique de fixation prévoit de pourvoir le dispositif de fixation avec un manchon qui vient en prise avec la paroi interne du col, soit par simple serrage, soit par une action combinée de serrage et d'encliquetage.It is indeed common in the field of perfumery, cosmetics or even pharmacy to use fixing devices to fix a dispensing member such as a pump or a valve in a tank opening which often occurs in the form of a collar. This neck generally comprises an internal wall, an external wall and an upper end wall connecting the internal wall to the external wall. The fixing device generally comprises receiving means adapted to fixedly receive the body of the pump or of the valve. Conventionally, the pump or valve body is forcibly engaged in a latching housing formed by the receiving means. On the other hand, the fixing device comprises fixing means able to come into engagement with the neck or the opening of the reservoir to hold it fixedly. There are various techniques for attaching the attachment device to or in the neck or the reservoir opening. These fixing means may for example be in the form of a split or continuous skirt which comes into engagement with the external wall of the neck. The split or continuous skirt may for example be formed with internal latching heads which are housed below a shoulder formed by the external wall of the neck. Another fixing technique provides for providing the fixing device with a sleeve which comes into engagement with the internal wall of the neck, either by simple tightening, or by a combined tightening and snapping action.
Un tel dispositif de fixation, outre sa fonction de fixation, doit normalement encore remplir une fonction d'étanchéité de manière à empêcher toute fuite de produit fluide entre le col du réservoir et le dispositif de fixation.Such a fixing device, in addition to its fixing function, must normally also fulfill a sealing function so as to prevent any leakage of fluid product between the neck of the reservoir and the fixing device.
Une technique bien connue pour réaliser l'étanchéité est l'utilisation d'un joint de col disposé de manière classique sur la paroi d'extrémité supérieure du col. Dans la plupart des dispositifs de fixation de l'art antérieur, la fonction de fixation est toujours dissociée de la fonction d'étanchéité : en d'autres termes, les moyens de fixation ne garantissent pas l'étanchéité et les moyens d'étanchéité ne garantissent pas la fixation. La présente invention a pour but de remédier à cet inconvénient précité de l'art antérieur en définissant un dispositif de fixation dont les moyens de fixation assurent simultanément la fonction d'étanchéité.A well-known technique for sealing is the use of a neck seal conventionally disposed on the upper end wall of the neck. In most fixing devices of the prior art, the fixing function is always dissociated from the sealing function: in other words, the fixing means do not guarantee sealing and the sealing means do not do not guarantee fixation. The object of the present invention is to remedy this aforementioned drawback of the prior art by defining a fixing device, the fixing means of which simultaneously ensure the sealing function.
Dans l'art antérieur, le document WO 84/01356 décrit une coupelle de fixation d'une valve sur un bidon aérosol. La coupelle est entièrement revêtue d'un matériau plastique qui peut être facilement chauffé à une haute température pour former une étanchéité entre la coupelle et le bidon. La température de fusion du matériau plastique revêtu sur la coupelle est de l'ordre de 600°F, soit 315°C. Les matériaux plastiques utilisés sont ceux capables de fondre sur une surface métallique. Les matériaux plastiques cités sont le polyéthylène, le propylène, le vinyle, le nylon, l'acétate ou d'autres matériaux plastiques. Ces matériaux plastiques sont donc fixés par fusion sur la surface métallique en appliquant une chaleur intense.In the prior art, the document WO 84/01356 describes a cup for fixing a valve on an aerosol can. The cup is completely coated with a plastic material which can be easily heated to a high temperature to form a seal between the cup and the container. The melting temperature of the plastic material coated on the cup is of the order of 600 ° F, or 315 ° C. The plastic materials used are those capable of melting on a metallic surface. The plastic materials mentioned are polyethylene, propylene, vinyl, nylon, acetate or other plastic materials. These plastic materials are therefore fixed by fusion on the metal surface by applying intense heat.
La présente invention a pour but de réaliser une fixation et une étanchéité simultanées sans appliquer de chaleur néfaste au produit fluide à distribuer. Pour atteindre ce but, la présente invention propose que les moyens de fixation comprennent une zone d'application revêtue d'un adhésif apte à venir en contact avec le col de réservoir. Plus simplement, le dispositif de fixation est collé sur le col de réservoir. Le collage assure en effet simultanément la fixation et l'étanchéité. Avantageusement, la zone d'application revêtue d'adhésif est destinée à venir en contact avec la paroi d'extrémité supérieure du col. De manière pratique, le dispositif de fixation comprend une bride annulaire ayant une face inférieure définissant la zone d'application. Cette bride annulaire est également connue sous le terme de plateau. En effet, il est facile d'appuyer fortement le plateau sur la paroi d'extrémité supérieure du col avec un outillage classique de presse. On peut ainsi dire que le joint de col classique de l'art antérieur a été remplacé dans la présente invention par un adhésif qui remplit en plus de sa fonction d'étanchéité une fonction de fixation.The object of the present invention is to provide simultaneous fixing and sealing without applying harmful heat to the fluid product to be dispensed. To achieve this object, the present invention proposes that the fixing means comprise an application area coated with an adhesive capable of coming into contact with the tank neck. More simply, the fixing device is glued to the tank neck. Bonding ensures simultaneous fixing and sealing. Advantageously, the adhesive coated application zone is intended to come into contact with the upper end wall of the neck. Conveniently, the fixing device comprises an annular flange having a lower face defining the application area. This annular flange is also known as a plate. Indeed, it is easy to strongly support the plate on the upper end wall of the neck with conventional press tools. We can say that the classic neck seal of art has been replaced in the present invention by an adhesive which fulfills, in addition to its sealing function, a fixing function.
Selon un autre aspect de l'invention, le dispositif de fixation comprend un manchon interne destiné à venir en prise étanche avec la paroi interne du col. La fonction de ce manchon interne est d'isoler l'adhésif du produit fluide stocké à l'intérieur du réservoir. En effet, dans de nombreux cas d'application, le produit fluide peut être contaminé par certains composants constitutifs de l'adhésif. Le manchon interne constitue ainsi une barrière empêchant le produit fluide de rentrer en contact avec l'adhésif. En outre, il complète ou renforce l'étanchéité au niveau du col de réservoir.According to another aspect of the invention, the fixing device comprises an internal sleeve intended to come into sealing engagement with the internal wall of the neck. The function of this internal sleeve is to isolate the adhesive from the fluid stored inside the tank. In fact, in many application cases, the fluid product can be contaminated with certain constituent components of the adhesive. The internal sleeve thus constitutes a barrier preventing the fluid product from coming into contact with the adhesive. In addition, it completes or strengthens the seal at the tank neck.
Selon une autre caractéristique de l'invention, le dispositif de fixation comprend une jupe externe destinée à s'étendre autour d'une paroi externe du col. La jupe externe peut contribuer à la fixation et/ou à l'étanchéité du dispositif de fixation sur le col du récipient. La jupe peut par exemple améliorer la stabilité du dispositif de fixation. Bien que cela ne soit pas nécessaire, la jupe externe peut comprendre des moyens d'accrochage aptes à coopérer avec la paroi externe du col. En effet, la fonction de fixation peut être entièrement garantie par l'adhésif. Une autre fonction possible de la jupe est de servir de support à une frette d'habillage qui vient la recouvrir afin d'améliorer l'esthétique du dispositif de fixation, et de ce fait, du distributeur dans son intégralité. La frette d'habillage peut en effet être engagée à force autour de la jupe externe.According to another characteristic of the invention, the fixing device comprises an external skirt intended to extend around an external wall of the neck. The outer skirt can contribute to the fixing and / or sealing of the fixing device on the neck of the container. The skirt can for example improve the stability of the fixing device. Although this is not necessary, the external skirt may include attachment means able to cooperate with the external wall of the neck. Indeed, the fixing function can be fully guaranteed by the adhesive. Another possible function of the skirt is to serve as a support for a covering band which comes to cover it in order to improve the aesthetics of the fixing device, and therefore of the dispenser in its entirety. The covering hoop can indeed be forcibly engaged around the outer skirt.
Selon une forme de réalisation pratique, le manchon interne et la jupe externe forment ensemble une gorge annulaire dont le fond est formé par la face inférieure de la bride annulaire qui relie le manchon à la jupe. L'adhésif peut ainsi être déposé ou appliqué de manière très simple au fond de la gorge annulaire.According to a practical embodiment, the internal sleeve and the external skirt together form an annular groove the bottom of which is formed by the underside of the annular flange which connects the sleeve to the skirt. The adhesive can thus be deposited or applied very simply to the bottom of the annular groove.
Avantageusement, l'adhésif est un adhésif à froid. Il peut par exemple s'agir d'une colle liquide ou pâteuse ou d'un ruban adhésif double face déposée sur la zone d'application. Ces adhésifs ne nécessitent aucune application ou dégagement de chaleur néfaste pour le produit fluide. L'invention a également pour objet un distributeur de produit fluide comprenant un organe de distribution de produit fluide, un réservoir ainsi qu'un dispositif de fixation selon l'invention. Avantageusement, l'organe de distribution est une pompe, le réservoir est en verre ou matière plastique et le dispositif de fixation en matière plastique.Advantageously, the adhesive is a cold adhesive. It may for example be a liquid or pasty glue or a double-sided adhesive tape deposited on the application area. These adhesives do not require any application or generation of harmful heat for the fluid product. The invention also relates to a fluid dispenser comprising a fluid dispenser member, a reservoir and a fixing device according to the invention. Advantageously, the dispensing member is a pump, the reservoir is made of glass or plastic and the fixing device is made of plastic.
L'invention sera plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif deux modes de réalisation de l'invention.The invention will be described more fully with reference to the accompanying drawings which give two embodiments 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 la partie haute d'un distributeur de produit fluide selon une première forme de réalisation de l'invention, etFIG. 1 is a vertical cross-section view through the upper part of a fluid dispenser according to a first embodiment of the invention, and
La figure 2 est une vue similaire à celle de la figure 1 pour une seconde forme de réalisation de l'invention.Figure 2 is a view similar to that of Figure 1 for a second embodiment of the invention.
En se référant à la figure 1, on voit un organe de distribution 2 qui peut être une pompe ou une valve. Cet organe de distribution comprend un corps 20 formant une collerette renforcée 21 au niveau de son extrémité supérieure. Au- delà de la collerette, l'organe de distribution 2 forme une tige de soupape 22 destinée à être coiffée d'une tête de distribution, qui peut par exemple se présenter sous la forme d'un poussoir intégrant un gicleur. La collerette renforcée 21 sert traditionnellement d'organe de préhension pour la fixation de l'organe de distribution par le dispositif de fixation, comme on le verra ci-après.Referring to Figure 1, there is shown a dispensing member 2 which may be a pump or a valve. This dispensing member comprises a body 20 forming a reinforced flange 21 at its upper end. Beyond the flange, the dispensing member 2 forms a valve stem 22 intended to be capped with a dispensing head, which can for example be in the form of a pusher incorporating a nozzle. The reinforced flange 21 traditionally serves as a gripping member for fixing the dispensing member by the fixing device, as will be seen below.
Le réservoir n'est pas représenté dans sa totalité, seul le col 3 étant visible. Ce col 3 comprend une paroi interne 31, une paroi d'extrémité supérieure 32 et une paroi externe 33. La paroi d'extrémité supérieure 32 peut être parfaitement plane comme représenté sur la figure 1, mais elle peut également être formée avec un ou plusieurs joncs concentriques réalisés en relief. La paroi d'extrémité supérieure 32 se prolonge vers l'intérieur du col par un chanfrein annulaire 321. Au-delà de ce chanfrein, la paroi interne 31 forme une section d'ouverture rétrécie sensiblement cylindrique 311. En dessous de cette section 311, la paroi interne 31 forme une section légèrement évidée 312 qui se prolonge vers le bas par une autre section sensiblement cylindrique 313. D'autre part, la paroi d'extrémité supérieure 32 se prolonge vers l'extérieur par une section arrondie 322 qui se prolonge elle-même par la paroi extérieure 33. La paroi externe 33 forme d'abord une section sensiblement cylindrique 330 qui se prolonge par un épaulement vers le bas 331. Cet épaulement 331 se raccorde à une autre section 332 dont le diamètre est inférieur à celui de la section 330. Il s'agit là d'une configuration tout à fait classique pour un col de réservoir, et plus particulièrement un col de réservoir réalisé en verre. En effet, le verre est couramment utilisé pour réaliser des flacons, et plus généralement des réservoirs dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie. Le dispositif de fixation, qui est désigné dans son ensemble par la référence numérique 1, comprend une bague de fixation 10 sur laquelle est montée une frette d'habillage 167. La bague de fixation 10 est de préférence réalisée en matière plastique, alors que la frette d'habillage 167 est de préférence réalisée en métal. La bague de fixation 10 comprend des moyens de réception 11 qui se présentent sous la forme d'un logement d'encliquetage délimité par un cordon d'encliquetage 111. La collerette renforcée 21 de l'organe de distribution 2 est ainsi engagée en force dans le logement et y est maintenue par le cordon d'encliquetage 111. Le logement d'encliquetage est percé par une ouverture de passage 112 à travers laquelle passe la tige de soupape 22 de l'organe de distribution 2. A partir des moyens de réception 11, la bague s'étend radialement vers l'extérieur pour former une bride annulaire 13 qui se présente sous la forme d'un plateau annulaire. La bague de fixation se prolonge également vers le bas au niveau de la jonction entre les moyens de réception 11 et de la bride annulaire 13 sous la forme d'un manchon interne 14. Le cordon d'encliquetage 111 est situé à l'extrémité supérieure du manchon interne 19 qui s'étend librement vers le bas. La bride annulaire 13 se prolonge, au niveau de sa périphérie externe, vers le haut pour former une douille supérieure 16 et vers le bas pour former une jupe externe 17. La jupe externe 17 peut être continue ou fendue de manière à former des pattes verticales séparées par des fentes verticales. L'extrémité inférieure de la jupe peut être pourvue d'un cordon ou de têtes de maintien 18 qui font saillie radialement verts l'intérieur.The reservoir is not shown in its entirety, only the neck 3 being visible. This neck 3 comprises an internal wall 31, an upper end wall 32 and an external wall 33. The upper end wall 32 can be perfectly flat as shown in FIG. 1, but it can also be formed with one or more concentric rods made in relief. The upper end wall 32 is extended towards the inside of the neck by an annular chamfer 321. Beyond this chamfer, the internal wall 31 forms a substantially cylindrical narrowed opening section 311. Below this section 311, the internal wall 31 forms a slightly hollowed-out section 312 which extends downwards through another substantially cylindrical section 313. On the other hand, the wall upper end 32 extends outwardly through a rounded section 322 which itself extends through the outer wall 33. The outer wall 33 first forms a substantially cylindrical section 330 which is extended by a downward shoulder 331. This shoulder 331 is connected to another section 332 whose diameter is smaller than that of section 330. This is a completely conventional configuration for a tank neck, and more particularly a tank neck made of glass. In fact, glass is commonly used to make bottles, and more generally reservoirs in the field of perfumery, cosmetics or even pharmacy. The fixing device, which is designated as a whole by the reference numeral 1, comprises a fixing ring 10 on which is mounted a covering band 167. The fixing ring 10 is preferably made of plastic, while the covering hoop 167 is preferably made of metal. The fixing ring 10 comprises receiving means 11 which are in the form of a latching housing delimited by a latching cord 111. The reinforced flange 21 of the dispensing member 2 is thus engaged in force in the housing and is held there by the latching cord 111. The latching housing is pierced by a passage opening 112 through which the valve stem 22 of the dispensing member 2 passes. From the receiving means 11, the ring extends radially outward to form an annular flange 13 which is in the form of an annular plate. The fixing ring also extends downwards at the junction between the receiving means 11 and the annular flange 13 in the form of an internal sleeve 14. The latching cord 111 is located at the upper end of the inner sleeve 19 which extends freely downwards. The annular flange 13 extends, at its external periphery, upwards to form an upper bush 16 and downwards to form an external skirt 17. The external skirt 17 can be continuous or split so as to form vertical legs separated by vertical slits. The lower end of the skirt can be provided with a cord or holding heads 18 which project radially green inside.
La frette d'habillage 167 est disposée autour de la bague, en contact avec la douille 16 et/ou la jupe 17. La fixation de la frette 167 peut par exemple être réalisée par serrage sur au moins une partie de la hauteur de la douille 16 et/ou de la jupe 17. A son extrémité supérieure, la frette 167 peut former un rabat rentré de butée qui stoppe son engagement sur la bague.The covering hoop 167 is arranged around the ring, in contact with the sleeve 16 and / or the skirt 17. The fixing of the hoop 167 can for example be carried out by tightening over at least part of the height of the sleeve 16 and / or of the skirt 17. At its upper end, the hoop 167 may form a retracted flap of stop which stops its engagement on the ring.
Selon l'invention, la bride annulaire 13 comprend une face inférieure qui définit une zone d'application 14 revêtue ou plus généralement pourvue d'un adhésif 15. Cet adhésif peut être pâteux, c'est-à-dire fluable, ou plus résistant de manière à conserver sensiblement sa forme. On peut par exemple constater que la zone d'application 14 est située au fond d'une gorge annulaire formée par le manchon interne 19 et la jupe externe 17, qui s'étendent sensiblement concentriquement. L'adhésif 15, qui peut être une colle, peut ainsi aisément être disposé au fond de la gorge en maintenant la bague de fixation à l'envers.According to the invention, the annular flange 13 comprises a lower face which defines an application area 14 coated or more generally provided with an adhesive 15. This adhesive may be pasty, that is to say flowable, or more resistant so as to substantially retain its shape. It can for example be seen that the application zone 14 is located at the bottom of an annular groove formed by the internal sleeve 19 and the external skirt 17, which extend substantially concentrically. The adhesive 15, which can be an adhesive, can thus easily be placed at the bottom of the groove while keeping the fixing ring upside down.
L'adhésif peut également se présenter sous la forme d'une rondelle d'adhésif double face. De préférence, l'adhésif ou la colle s'applique et réalise le contact à froid, c'est-à-dire sans besoin de chauffer et sans dégager de la chaleur.The adhesive can also be in the form of a double-sided adhesive washer. Preferably, the adhesive or glue is applied and makes the cold contact, that is to say without the need to heat and without giving off heat.
L'adhésif 15 est destiné à venir en contact avec la paroi d'extrémité supérieure 32 du col 3. Lors de la mise en place de la bague 10 sur le col 3, on peut exercer une pression de sorte que l'adhésif 15 est fortement pressé sur la paroi d'extrémité supérieure 32 du col 3. En fonction de la nature de l'adhésif, (col, double face, etc.) celui-ci peut plus ou moins être déformé sur la paroi d'extrémité supérieure, de sorte qu'une partie de l'adhésif peut même fluer au niveau du chanfrein 321 ou de la section externe arrondie 322.The adhesive 15 is intended to come into contact with the upper end wall 32 of the neck 3. When the ring 10 is placed on the neck 3, pressure can be exerted so that the adhesive 15 is strongly pressed on the upper end wall 32 of the neck 3. Depending on the nature of the adhesive (neck, double-sided, etc.) it may more or less be deformed on the upper end wall, so that part of the adhesive can even creep at the chamfer 321 or the rounded external section 322.
D'autre part, la paroi externe 191 du manchon 19, qui peut d'ailleurs être avantageusement réalisée de manière tronconique, vient en contact serrant contre la section d'ouverture rétrécie 311 du col 3. De manière plus générale, la manchon interne 19 doit venir, avec sa paroi externe 191, en contact d'appui étanche avec la paroi interne 31 du col 3. Il est particulièrement avantageux que le contact du manchon avec le col soit étanche pour ainsi isoler le produit fluide stocké dans le réservoir de l'adhésif 15 qui pourrait le contaminer. De plus, le contact du manchon avec le col améliore la tenue et la stabilité de la bague 10.On the other hand, the external wall 191 of the sleeve 19, which can moreover be advantageously made in a frustoconical manner, comes into tight contact against the narrowed opening section 311 of the neck 3. More generally, the internal sleeve 19 must come, with its outer wall 191, in sealed bearing contact with the inner wall 31 of the neck 3. It is particularly advantageous for the contact of the sleeve with the neck to be sealed, thereby isolating the fluid product stored in the adhesive tank 15 which could contaminate it. In addition, contact of the sleeve with the neck improves the strength and stability of the ring 10.
Quant à la jupe externe 17, elle peut venir en contact de la paroi externeAs for the outer skirt 17, it can come into contact with the outer wall
32 du col 3. Ce contact peut être serrant ou non et/ou étanche ou non. Dans la forme de réalisation de la figure 1, la jupe 17 s'étend avec son extrémité d'accrochage 18 jusqu'au niveau de l'épaulement 331 de manière à y réaliser un accrochage. Cet accrochage est d'ailleurs bloqué par la présence de la frette 167.32 of the neck 3. This contact can be tight or not and / or waterproof or not. In the embodiment of Figure 1, the skirt 17 extends with its hooking end 18 to the level of the shoulder 331 so as to engage there. This attachment is also blocked by the presence of the hoop 167.
La forme de réalisation représentée sur la figure 2 diffère de celle de la figure 1 en ce que la bague 10 ne forme pas de manchon interne 19 et en ce que la jupe externe 17 ne forme pas d'extrémité inférieure pourvue d'un cordon d'accrochage 18. Ainsi, à la fois l'étanchéité et la fixation sont entièrement assurées par l'adhésif 15 en contact étanche avec la paroi d'extrémité supérieure 32 du col 3. De plus, du fait que la jupe 17 ne comporte pas de cordon d'accrochage 18, la frette d'habillage 167 peut préalablement être mise en place sur la bague avant le montage de la bague sur le col.The embodiment shown in FIG. 2 differs from that of FIG. 1 in that the ring 10 does not form an internal sleeve 19 and in that the external skirt 17 does not form a lower end provided with a cord d 'hooking 18. Thus, both the sealing and the fixing are entirely ensured by the adhesive 15 in leaktight contact with the upper end wall 32 of the neck 3. In addition, because the skirt 17 does not have of attachment cord 18, the covering hoop 167 can be previously placed on the ring before mounting the ring on the neck.
Bien entendu, il est possible, à partir de ces deux modes de réalisation, de créer des variantes qui ne sortent pas du cadre de l'invention. Par exemple, on peut très bien réaliser une bague pourvue d'un manchon interne 19 et dépourvue de cordon d'accrochage 18 et inversement. Grâce à l'invention, on peut réaliser, de manière très simple et à moindre coût, une fixation étanche d'un dispositif de fixation sur un col de réservoir. Of course, it is possible, from these two embodiments, to create variants which do not depart from the scope of the invention. For example, it is very possible to produce a ring provided with an internal sleeve 19 and devoid of attachment cord 18 and vice versa. Thanks to the invention, it is possible to produce, in a very simple manner and at low cost, a sealed fixing of a fixing device on a tank neck.
