Description
La présente invention concerne un distributeur de produit fluide comprenant un réservoir et une tête de distribution à travers laquelle le produit fluide du réservoir est distribué. Le réservoir comprend une ouverture et la tête de distribution comprend une bague de fixation qui vient en prise dans l'ouverture. La bague et l'ouverture forment des moyens de montage final étanches qui permettent de fixer, en position finale de montage, la tête de distribution de manière stable et étanche dans l'ouverture du réservoir. De tels distributeurs de produit fluide sont fréquemment utilisés dans les domaines de la cosmétique, de la parfumerie ou encore de la pharmacie.The present invention relates to a fluid dispenser comprising a reservoir and a dispensing head through which the fluid product of the reservoir is dispensed. The reservoir comprises an opening and the dispensing head comprises a fixing ring that engages in the opening. The ring and the opening form sealed final mounting means which fix, in final mounting position, the dispensing head stably and tightly in the opening of the tank. Such fluid dispensers are frequently used in the fields of cosmetics, perfumery or pharmacy.
Dans le domaine de la cosmétique, on utilise parfois des réservoirs dont l'ouverture est particulièrement grande, pouvant présenter un diamètre supérieur à 3 ou 4 cm. Le réservoir peut par exemple se présenter sous la forme d'un godet cylindrique à l'intérieur duquel est monté de manière coulissante un piston suiveur qui est destiné à se déplacer dans le godet à mesure que du produit fluide est extrait du réservoir. L'ouverture du réservoir s'étend alors dans le prolongement du godet et présente le même diamètre que le réservoir. En association avec un tel réservoir, on utilise fréquemment une tête de distribution de diamètre important, mais de hauteur réduite. Cela signifie que la tête de distribution ne pénètre que faiblement à l'intérieur de l'ouverture du réservoir. Un type de tête de distribution connu présente une face inférieure sensiblement plane, contre laquelle le piston suiveur vient en contact lorsque le réservoir est vide. En résumé, un tel distributeur comprend un réservoir dont l'ouverture est grande et une tête de distribution qui pénètre faiblement à l'intérieur du réservoir.In the field of cosmetics, it is sometimes possible to use reservoirs whose opening is particularly large, which may have a diameter greater than 3 or 4 cm. The reservoir may for example be in the form of a cylindrical cup inside which is slidably mounted a follower piston which is intended to move in the bucket as fluid is extracted from the reservoir. The opening of the reservoir then extends in the extension of the bucket and has the same diameter as the reservoir. In association with such a reservoir, a distribution head of large diameter, but of reduced height, is frequently used. This means that the dispensing head penetrates only weakly inside the opening of the tank. A known type of dispensing head has a substantially flat bottom face, against which the follower piston comes into contact when the reservoir is empty. In summary, such a dispenser comprises a reservoir whose opening is large and a dispensing head which penetrates weakly inside the tank.
Lors du montage d'un tel distributeur, on commence d'abord par remplir le réservoir avec du produit fluide. Ensuite, on dépose la tête de distribution dans l'ouverture du réservoir sans réaliser le montage final. Il n'y a pas encore d'étanchéité entre la tête de distribution et le réservoir. Une étape suivante optionnelle, mais de plus en plus courante, consiste à soumettre le distributeur à un vide pour évacuer l'air présent dans le réservoir. L'étape suivante finale consiste à monter de manière définitive et étanche la tête de distribution sur le réservoir.When mounting such a dispenser, it first begins by filling the tank with fluid. Then, the dispensing head is deposited in the opening of the tank without performing the final assembly. There is still no seal between the dispensing head and the reservoir. An optional next step, but more and more common, is to subject the dispenser to a vacuum to evacuate the air in the tank. The final final step is to permanently mount and seal the dispensing head on the tank.
Pour réaliser ces différentes étapes, les distributeurs sont acheminés à travers différents postes au moyen d'un chemin de convoyage. Plus précisément, le réservoir est déposé sur le chemin de convoyage qui permet de le convoyer d'un poste à un autre où sont réalisées des différentes étapes de montage. Cependant, étant donné que la tête de distribution est simplement déposée dans l'ouverture du réservoir après l'étape de remplissage, il arrive parfois que la tête de distribution tombe du réservoir lorsqu'il est acheminé vers l'étape suivante de conditionnement sous vide ou de montage final. La chute de la tête de distribution peut être causée par le démarrage brutal du chemin de convoyage qui emmène le réservoir rempli de produit fluide. La tête de distribution tombe d'autant plus facilement qu'elle pénètre très faiblement à l'intérieur du réservoir, et que l'ouverture de réservoir est importante. Il suffit d'une seule tête de distribution qui tombe de son réservoir pour bloquer toute la chaîne de montage.To achieve these different steps, the distributors are routed through different stations by means of a conveying path. More specifically, the tank is deposited on the conveying path which allows to convey it from one station to another where different stages of assembly are performed. However, since the dispensing head is simply deposited in the tank opening after the filling step, it sometimes happens that the dispensing head falls from the reservoir when it is routed to the next vacuum conditioning stage. or final assembly. The drop of the dispensing head can be caused by the sudden start of the conveying path which takes the reservoir filled with fluid product. The dispensing head falls all the more easily as it penetrates very weakly inside the tank, and the tank opening is important. It only takes one dispensing head that falls from its tank to block the entire assembly line.
Le document
C'est un but de la présente invention que de remédier à cet inconvénient précité de l'art antérieur en définissant un distributeur dont la tête de distribution ne risque pas d'être désolidarisée de son réservoir sur la chaîne de montage entre le moment où la tête est déposée sur le réservoir et le moment où la tête de distribution est définitivement montée sur le réservoir. Un but de la présente invention est d'empêcher la chute de la tête de distribution tout en conservant la possibilité de soumettre le distributeur à un conditionnement sous vide. La présente invention s'applique tout particulièrement au domaine de la cosmétique avec le type de distributeur précité, mais elle peut également s'appliquer à d'autres domaines avec des types de réservoir et de tête de distribution différents.It is an object of the present invention to overcome this aforementioned drawback of the prior art by defining a dispenser whose dispensing head is not likely to be separated from its reservoir on the assembly line between the moment when the head is deposited on the tank and the moment when the dispensing head is permanently mounted on the tank. An object of the present invention is to prevent the drop of the dispensing head while retaining the possibility of subjecting the dispenser to vacuum packaging. The present invention is particularly applicable to the field of cosmetics with the type of dispenser above, but it can also apply to other areas with different types of tank and dispensing head.
Pour atteindre ces buts, la présente invention propose que la bague et l'ouverture forment en outre des moyens d'encliquetage provisoire permettant de fixer, en position provisoire prémontée, la tête de distribution de manière provisoire et non étanche dans l'ouverture du réservoir. Avantageusement, les moyens de montage final sont des moyens d'encliquetage. Ainsi, la tête de distribution est rendue solidaire du réservoir en position provisoire prémontée, ce qui évite tout risque de perte ou de chute de la tête de distribution. D'autre part, étant donné que le prémontage provisoire n'est pas étanche, il est possible de soumettre le distributeur, et plus particulièrement le contenu du réservoir, à un vide pour évacuer l'air qu'il contient. Ensuite, la tête de distribution est montée de manière définitive et étanche sur le réservoir. En d'autres termes, la tête de distribution est d'abord préencliquetée de manière non étanche sur le réservoir, puis dans un second temps, la tête est définitivement encliquetée de manière étanche sur le réservoir. Entre les deux encliquetages, la tête de distribution est solidaire du réservoir, mais il est toujours possible de réaliser un conditionnement sous vide.To achieve these aims, the present invention proposes that the ring and the opening also form temporary snap-fastening means for fixing, temporarily in the pre-assembled position, the dispensing head temporarily and unsealed in the opening of the reservoir. . Advantageously, the final mounting means are latching means. Thus, the dispensing head is secured to the tank in premounted provisional position, which avoids any risk of loss or of falling of the dispensing head. On the other hand, since the provisional pre-assembly is not waterproof, it is possible to subject the dispenser, and more particularly the contents of the tank, to a vacuum to evacuate the air contained therein. Then, the dispensing head is mounted permanently and sealed on the tank. In other words, the dispensing head is first preassembled in a non-sealed manner on the reservoir, then in a second step, the head is permanently snapped tightly on the reservoir. Between the two snaps, the dispensing head is integral with the reservoir, but it is still possible to perform vacuum packaging.
Selon une forme de réalisation pratique, les moyens de montage comprennent une première rainure d'encliquetage formée au niveau de l'ouverture et une première nervure d'encliquetage formée par la bague de fixation, la première nervure étant en prise encliquetée dans la première rainure en position finale de montage.According to a practical embodiment, the mounting means comprise a first detent groove formed at the opening and a first detent rib formed by the fixing ring, the first rib being engaged snapped into the first groove. in final assembly position.
Avantageusement, les moyens de prémontage comprennent une seconde rainure d'encliquetage formée au niveau de l'ouverture et la première nervure d'encliquetage formée par la bague de fixation, la première nervure étant en prise encliquetée dans la seconde rainure en position prémontée.Advantageously, the pre-assembly means comprise a second detent groove formed at the opening and the first detent rib formed by the fixing ring, the first rib being in engagement snapped into the second groove in the premounted position.
De préférence, l'ouverture définit un bord annulaire supérieur, la seconde rainure étant située plus près du bord annulaire que la première rainure.Preferably, the opening defines an upper annular edge, the second groove being located closer to the annular edge than the first groove.
Selon une caractéristique particulièrement intéressante, la bague forme une seconde nervure qui vient s'encliqueter de manière étanche dans la seconde rainure en position finale de montage. Ainsi, en position finale de montage, la tête de distribution est doublement encliquetée dans l'ouverture du réservoir, augmentant ainsi la stabilité de la tête sur le réservoir, mais également l'étanchéité entre la bague et l'ouverture.According to a particularly interesting characteristic, the ring forms a second rib which snaps tightly into the second groove in the final mounting position. Thus, in the final mounting position, the dispensing head is doubly snapped into the opening of the tank, thus increasing the stability of the head on the tank, but also the seal between the ring and the opening.
Selon une autre caractéristique de l'invention, l'ouverture définit un bord annulaire supérieur, la bague de fixation formant une bride périphérique qui vient en appui sur le bord de l'ouverture en position finale de montage.According to another characteristic of the invention, the opening defines an upper annular edge, the fixing ring forming a peripheral flange which bears on the edge of the opening in the final mounting position.
Selon un autre aspect de l'invention, le réservoir comprend un piston suiveur qui coulisse de manière étanche à l'intérieur d'un fût fermé par le réservoir, ce piston suiveur se déplaçant entre la position prémontée et la position finale de montage pour éviter toute montée en pression dans le réservoir. Cette caractéristique, qui peut être mise en oeuvre indépendamment du prémontage provisoire, permet de manière très simple d'empêcher toute surpression à l'intérieur du réservoir qui résulterait de la course étanche de la tête de distribution à l'intérieur de l'ouverture du réservoir lors du montage.According to another aspect of the invention, the reservoir comprises a follower piston which slides in a sealed manner inside a barrel closed by the reservoir, this follower piston moving between the pre-assembled position and the final mounting position to avoid any rise in pressure in the tank. This characteristic, which can be implemented independently of the temporary pre-assembly, makes it possible in a very simple way to prevent any overpressure inside the tank that would result from the sealed race of the dispensing head inside the opening of the tank during assembly.
Selon une forme de réalisation avantageuse, la tête de distribution présente une face inférieure orientée vers le réservoir, cette face inférieure formant un toit de fermeture pour le réservoir, cette face inférieure étant sensiblement plane et faisant très peu saillie dans le réservoir en dessous de la bague de fixation. En effet, la présente invention trouve un avantage particulier lorsque la tête de distribution présente une face inférieure plane qui ne pénètre que faiblement à l'intérieur du réservoir. Comme susmentionné, ceci est le cas des pompes cosmétiques qui sont montées sur des réservoirs présentant une ouverture de forte section.According to an advantageous embodiment, the dispensing head has a lower face oriented towards the reservoir, this lower face forming a closing roof for the reservoir, this lower face being substantially flat and projecting very little into the reservoir below the reservoir. fixing ring. Indeed, the present invention finds a particular advantage when the dispensing head has a flat bottom face which penetrates only slightly inside the tank. As mentioned above, this is the case of cosmetic pumps which are mounted on tanks having a large section opening.
Selon un autre aspect de l'invention, le réservoir comprend un fût de coulissement et un piston suiveur qui coulisse dans le fût, l'ouverture s'étendant dans le prolongement du fût. Cela signifie que l'ouverture du réservoir présente un diamètre sensiblement égal à celui du réservoir où coulisse le piston suiveur.According to another aspect of the invention, the reservoir comprises a sliding shaft and a follower piston which slides in the barrel, the opening extending in the extension of the barrel. This means that the opening of the reservoir has a diameter substantially equal to that of the reservoir where the follower piston slides.
L'esprit de l'invention réside dans le fait de prémonter, de manière provisoire et non étanche, une tête de distribution sur un réservoir dans l'attente du montage final étanche. Ce prémontage provisoire se fait par encliquetage. 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 spirit of the invention lies in premounting, provisionally and not sealed, a dispensing head on a tank in waiting for the final sealed assembly. This provisional pre-assembly is done by snapping. The invention will now be more fully described with reference to the accompanying drawings giving by way of non-limiting example an embodiment of the invention.

Le distributeur de produit fluide représenté sur les
Le réservoir de produit fluide 1 comprend un godet sensiblement cylindrique comprenant un fût de coulissement cylindrique 15 obturé à son extrémité inférieure par un fond 16. L'extrémité opposée du fût 15 définit une ouverture 11 dont la section est sensiblement ou parfaitement identique à celle du fût 15. Par conséquent, le réservoir 1 définit une ouverture 11 de section importante, puisqu'elle s'étend exactement dans le prolongement du fût 15. Le réservoir 1 comprend également un piston suiveur 17 qui est monté coulissant de manière étanche à l'intérieur du fût 15. Le piston suiveur 17 est initialement disposé à proximité du fond 16, mais on peut remarquer sur la
Selon l'invention, comme représenté sur les
La tête de distribution 2 comprend une pompe 3 définissant une entrée 31 communiquant avec le réservoir 1. La pompe 3 définit une chambre de pompe 32 de volume variable permettant de mettre le produit fluide sous pression. La pompe comprend également une bague de fixation 33 qui vient en prise avec l'ouverture 11 du réservoir. La tête de distribution comprend également un poussoir 4 associé à la pompe 3 pour l'actionner. Optionnellement, la tête de distribution comprend un capot de protection 5 monté de manière amovible sur la bague de fixation 33 et masquant le poussoir 4. Il s'agit là d'une conception tout à fait conventionnelle pour une tête de distribution dans le domaine de la cosmétique, de la pharmacie ou encore de la parfumerie.The dispensing

Le distributeur dans cette position provisoire prémontée peut ainsi être acheminé sur le chemin de convoyage jusqu'au poste de montage final étanche, et optionnellement à un poste d'évacuation par le vide. Il n'y aucun risque de désolidariser la tête du réservoir du fait de l'encliquetage de la première nervure d'encliquetage 34 à l'intérieur de la seconde rainure d'encliquetage 13, qui constituent ensemble des moyens de prémontage provisoires permettant de fixer la tête de distribution de manière provisoire et non étanche dans l'ouverture du réservoir.The dispenser in this premounted provisional position can thus be conveyed on the conveyor path to the sealed final assembly station, and optionally to a vacuum evacuation station. There is no risk of detaching the tank head due to the snap of the
