Description

Dispositif de distribution de produit comprenant une pompe et un embout de distribution  Product dispensing device comprising a pump and a dispensing nozzle
La présente invention concerne un dispositif de distribution de produit rapporté sur le col d'un réservoir. Par exemple un dispositif de distribution de médicament sous forme de spray comprenant une pompe, tel qu'un dispositif de pulvérisation nasale. The present invention relates to a product dispensing device attached to the neck of a tank. For example, a drug delivery device in the form of a spray comprising a pump, such as a nasal spray device.
On sait que l'on cherche de plus en plus à limiter ou supprimer l'utilisation de conservateurs chimiques dans les produits, tout particulièrement dans le domaine médical. En conséquence, il est important qu'un dispositif de distribution assure la plus grande étanchéité possible (aux liquides, aux gaz, aux bactéries) entre l'extérieur et l'intérieur du dispositif ou du réservoir, c'est-à-dire tout au long du chemin parcouru par le produit, pour éviter que des bactéries se développent et contaminent le produit. De tels dispositifs sont souvent qualifiés de dispositifs " preservative free ". Ils peuvent être pourvus d'un embout de distribution rapporté sur la pompe, comprenant un clapet anti-retour disposé juste avant l'orifice de distribution du produit et empêchant que des bactéries se développent dans l'embout de distribution. Un tel embout est par exemple décrit dans la publication FR 2887232. It is known that there is increasing interest in limiting or eliminating the use of chemical preservatives in products, especially in the medical field. Accordingly, it is important that a dispensing device ensures the greatest possible seal (to liquids, gases, bacteria) between the outside and the inside of the device or reservoir, that is to say all along the path traveled by the product, to prevent bacteria from developing and contaminate the product. Such devices are often referred to as "preservative free" devices. They may be provided with a dispensing nozzle attached to the pump, comprising a non-return valve disposed just before the dispensing orifice of the product and preventing bacteria from developing in the dispensing tip. Such a tip is for example described in the publication FR 2887232.
La présente invention a notamment pour but de fournir un dispositif de distribution dans lequel le risque de développement de bactéries est encore plus réduit. A cet effet, l'invention a pour objet un dispositif de distribution de produit, à rapporter sur le col d'un réservoir, caractérisé en ce qu'il comprend : The present invention is intended in particular to provide a dispensing device in which the risk of developing bacteria is even more reduced. For this purpose, the subject of the invention is a product dispensing device, to be carried on the neck of a reservoir, characterized in that it comprises:
- une pompe comprenant une chambre de dosage,  a pump comprising a metering chamber,
- un embout de distribution rapporté sur la pompe, comprenant une surface d'appui pour l'activation du dispositif par appui d'un utilisateur,  a dispensing nozzle attached to the pump, comprising a bearing surface for activating the device by a user,
- un capot de protection du dispositif,  a protective cover of the device,
- un collier de serrage, portant le capot, et  - a hose clamp, carrying the hood, and
- un organe de fixation du dispositif sur le col du réservoir, comprenant des moyens d'accrochage de l'organe autour du col, activables par coulissement du collier par rapport à l'organe de fixation depuis une configuration de pré- assemblage vers une configuration d'assemblage, une bague intérieure de a device fixing member on the neck of the reservoir, comprising means for fastening the member around the neck, activatable by sliding the collar relative to the fixing member from a predetermined configuration; assembly to an assembly configuration, an inner ring of
1 . centrage de la pompe sur le réservoir et une bague extérieure portant des moyens de retenue de l'embout de distribution.  1. centering of the pump on the reservoir and an outer ring carrying means for retaining the dispensing nozzle.
Ainsi, on propose d'utiliser un organe de fixation garantissant d'une part que le dispositif ne peut pas être facilement démonté du réservoir, d'autre part que l'embout de distribution ne peut pas être facilement démonté de la pompe, si bien que les risques de perte de stérilité, par exemple du fait de l'introduction d'air extérieur ou de bactéries dans le réservoir ou dans le dispositif, accidentellement ou volontairement, sont particulièrement réduits. En effet, le dispositif est fixé sur le réservoir grâce aux moyens d'accrochage, qui assurent une forme d'encliquetage activé par le collier de serrage, et qui constituent un mode de fixation quasiment indémontable par l'utilisateur, à la différence d'une fixation par vissage. Ce type de fixation est assimilable à une fixation " snap-on ". Outre cette fonction de fixation par snap-on, l'organe de fixation assure également une retenue de l'embout de distribution sur le dispositif, grâce à sa bague extérieure, qui garantit que cet embout ne pourra pas être retiré de la pompe sur lequel il est rapporté, même avec une force conséquente. On notera que l'embout de distribution est ainsi retenu de deux façons distinctes sur le dispositif : d'une part il est fixé sur la pompe, en étant rapporté sur une partie mobile de la pompe, par exemple par serrage, d'autre part il est retenu par la bague extérieure de l'embout, qui empêche ainsi l'arrachage de l'embout fixé sur la pompe. On notera par ailleurs que le dispositif proposé ci-dessus peut être assemblé sur le réservoir en une seule étape, ce qui est très avantageux. En effet, le dispositif de distribution constitue un module qui porte tous les éléments de distribution à rapporter sur le réservoir, en particulier la pompe, l'embout de distribution et le capot de protection. Ces éléments forment ainsi un module, pré-assemblé grâce à l'organe de fixation. Aussi, pour assembler le réservoir et le dispositif de protection, il est uniquement nécessaire de disposer le dispositif en position pré-assemblée sur le col du réservoir et de faire coulisser le collier de serrage via un simple appui sur le capot de protection afin d'activer les moyens d'accrochage. En effet, le capot étant porté par le collier de serrage, un appui sur le capot peut être directement transmis au collier. Ce montage en une seule étape est intéressant car l'intérieur du dispositif de distribution est protégé par le capot et n'est donc pas en contact avec l'extérieur, ce qui évite tout risque de contamination lors de l'assemblage final. Ce mode de réalisation permet que le dispositif de dosage soit fabriqué dans un endroit différent de celui dans lequel il est assemblé sur le flacon sans encourir le risque de pollution particulaire. Thus, it is proposed to use a fastener ensuring on the one hand that the device can not be easily removed from the reservoir, on the other hand that the dispensing tip can not be easily removed from the pump, so that that the risks of loss of sterility, for example due to the introduction of outside air or bacteria into the tank or into the device, accidentally or voluntarily, are particularly reduced. Indeed, the device is attached to the tank by means of hooking means, which provide a snap-on shape activated by the clamp, and which constitute a method of fixing almost unmountable by the user, unlike a fastening by screwing. This type of attachment is similar to a "snap-on" fixation. In addition to this snap-on attachment function, the fastener also ensures retention of the dispensing nozzle on the device, thanks to its outer ring, which ensures that this nozzle can not be removed from the pump on which it is reported, even with a consequent force. It will be noted that the dispensing nozzle is thus retained in two distinct ways on the device: on the one hand it is fixed on the pump, being attached to a movable part of the pump, for example by clamping, on the other hand it is retained by the outer ring of the nozzle, which thus prevents tearing of the nozzle attached to the pump. Note also that the device proposed above can be assembled on the tank in one step, which is very advantageous. Indeed, the dispensing device is a module that carries all the distribution elements to report on the reservoir, in particular the pump, the dispensing tip and the protective cap. These elements thus form a module, pre-assembled thanks to the fastener. Also, to assemble the tank and the protective device, it is only necessary to have the device in the pre-assembled position on the neck of the tank and to slide the clamping collar by simply pressing on the protective cover in order to activate the hooking means. Indeed, the hood being carried by the clamp, a support on the cover can be directly transmitted to the collar. This assembly in one step is interesting because the inside of the dispensing device is protected by the cover and is therefore not in contact with the outside, which avoids any risk of contamination during final assembly. This embodiment allows the dosing device to be manufactured in a different from the one in which it is assembled on the bottle without incurring the risk of particulate pollution.
On notera que la chambre de dosage de la pompe est de préférence obturée, en partie haute, par un premier pointeau formant valve anti-retour. Par ailleurs, l'embout de distribution comprend éventuellement un second pointeau, formant clapet anti-retour. It should be noted that the dosing chamber of the pump is preferably closed at the top by a first needle valve forming a non-return valve. Furthermore, the dispensing tip optionally comprises a second needle, forming a non-return valve.
Le dispositif de distribution peut en outre comporter l'une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison. The dispensing device may further comprise one or more of the following features, taken alone or in combination.
- Le collier de serrage comprend des moyens amovibles d'encliquetage du capot, de préférence sous forme d'une rainure annulaire. Ainsi, comme le capot est rattaché au collier, lui-même rattaché à l'organe de fixation qui porte la pompe et l'embout de distribution, la manipulation du capot seul permet de manipuler tout le dispositif. - The clamp comprises removable means for latching the cover, preferably in the form of an annular groove. Thus, as the cover is attached to the collar, itself attached to the fastener which carries the pump and the dispensing tip, the manipulation of the cover alone allows to manipulate the entire device.
- La bague intérieure de centrage de la pompe comprend une zone de renfort d'une patte élastique devant être passée en force pour la distribution de produit. Une telle patte élastique peut-être utilisée pour constituer un point dur d'activation, qui garantit que l'utilisateur exerce un appui suffisant sur le dispositif pour assurer la distribution d'une dose complète de produit, ce qui est particulièrement important dans le cas de médicaments. - L'embout de distribution comprend une enveloppe portant d'une part la surface d'appui et d'autre part une bague de retenue de l'embout, montée coulissante par rapport à la bague extérieure de l'organe de fixation, de préférence à l'intérieur de cette bague, et coopérant par butée avec les moyens de retenue portés par l'organe de fixation. La surface d'appui est en générale destinée à être en contact avec deux doigts de l'utilisateur. Elle se présente par exemple sous forme de deux ailettes s'étendant radialement, c'est-à-dire perpendiculairement à l'axe de la bague de retenue. De préférence, l'enveloppe comporte en outre un logement de réception d'un pointeau formant clapet anti-retour, obturant l'orifice de distribution de produit par rappel élastique exercé par un ressort. - The inner ring centering of the pump comprises a reinforcing zone of an elastic tab to be passed in force for the product distribution. Such an elastic tab can be used to constitute a hard point of activation, which ensures that the user exerts sufficient support on the device to ensure the distribution of a full dose of product, which is particularly important in the case of drugs. - The dispensing nozzle comprises a casing bearing on the one hand the bearing surface and on the other hand a retaining ring of the nozzle, slidably mounted relative to the outer ring of the fastener, preferably inside this ring, and cooperating by abutment with the retaining means carried by the fixing member. The bearing surface is generally intended to be in contact with two fingers of the user. It is for example in the form of two fins extending radially, that is to say perpendicular to the axis of the retaining ring. Preferably, the casing further comprises a housing for receiving a needle valve forming a non-return valve, closing the product dispensing orifice by elastic return exerted by a spring.
- L'embout de distribution comprend, outre la bague de retenue de l'embout, une embase fixée sur une partie mobile de la pompe. L'embase et la bague de retenue sont deux parties distinctes de l'embout, l'embase étant de préférence rapportée à l'intérieur de l'enveloppe et présentant une partie tubulaire venant s'emmancher sur la partie mobile de la pompe de façon étanche. La partie tubulaire de l'embase est au moins en partie à l'intérieur de la bague de retenue, en étant coaxiale avec cette bague. - The dispensing tip comprises, in addition to the retaining ring of the tip, a base fixed on a moving part of the pump. The base and the retaining ring are two distinct parts of the nozzle, the base being preferably attached to the inside of the casing and having a tubular part coming to fit on the movable part of the pump so that waterproof. The tubular part of the base is at least partly inside the retaining ring, being coaxial with this ring.
- Les moyens de retenue comprennent un ergot de retenue, formant une butée pour une nervure annulaire ménagée sur la bague de retenue. Bien sûr, on comprend que les moyens de retenue peuvent comporter plusieurs ergots. Un avantage d'une nervure annulaire continue réside dans le fait qu'il n'est pas nécessaire de prévoir une disposition angulaire particulière de l'embout lors de son montage sur le dispositif. - La bague extérieure de l'organe de fixation porte sur sa surface extérieure une butée supérieure de maintien du collier de serrage dans sa configuration de pré-assemblage du dispositif. Cette butée permet de maintenir le collier fixe sur l'organe, avant son assemblage sur le réservoir. - Les moyens d'accrochage de l'organe autour du col comprennent une butée inférieure de maintien du collier de serrage dans sa configuration de préassemblage du dispositif. Cette butée permet de maintenir le collier fixe par rapport à l'organe, avant son assemblage sur le réservoir, et peut servir d'appui au collier de serrage pour déformer des moyens déformables lorsqu'il coulisse. De préférence, la butée inférieure est portée par des moyens déformables, par exemple des moyens élastiques. - The retaining means comprise a retaining lug, forming a stop for an annular rib formed on the retaining ring. Of course, it is understood that the retaining means may comprise a plurality of lugs. An advantage of a continuous annular rib lies in the fact that it is not necessary to provide a particular angular disposition of the nozzle when it is mounted on the device. - The outer ring of the fixing member carries on its outer surface an upper stop for holding the clamp in its pre-assembly configuration of the device. This stop makes it possible to maintain the fixed collar on the member, before its assembly on the tank. - The fastening means of the member around the neck comprises a lower stop for holding the clamp in its preassembly configuration of the device. This stop makes it possible to maintain the fixed collar relative to the member, before it is assembled on the reservoir, and can serve as a support for the clamping collar to deform deformable means when it slides. Preferably, the lower stop is carried by deformable means, for example elastic means.
- L'organe de fixation est en matière plastique, ce qui est particulièrement indiqué dans le domaine médical car cela évite de générer des particules nuisibles. - The fastener is plastic, which is particularly appropriate in the medical field because it avoids generating harmful particles.
- Le collier de serrage est configuré de telle sorte qu'un appui sur le capot est directement transmis au collier de serrage, de façon à le faire passer de sa configuration de pré-assemblage à sa configuration d'assemblage. A cet effet, le collier de serrage comporte une portée d'appui du capot, de préférence sous forme d'une collerette extérieure faisant saillie d'une paroi principale du collier. L'invention a par ailleurs pour objet un ensemble d'un réservoir et d'un dispositif selon l'une quelconque des revendications précédentes, dans lequel le collier de serrage peut prendre sur le col du réservoir une position pré-assemblée et une position assemblée, les moyens d'accrochage de l'organe autour du col comprenant des moyens déformables, qui sont non déformés en position préassemblée et qui sont déformés en position assemblée, en étant maintenus déformés par le collier de serrage. On notera cependant que, selon un autre mode de réalisation, les moyens déformables peuvent être déformés en position préassemblée et non déformés en position assemblée, en étant maintenus non déformés par le collier de serrage. De préférence, les moyens déformables sont élastiques. - The clamp is configured so that a support on the cover is directly transmitted to the clamp, so that it moves from its pre-assembly configuration to its assembly configuration. For this purpose, the clamping collar comprises a bearing support of the cover, preferably in the form of an outer collar projecting from a main wall of the collar. The invention furthermore relates to an assembly of a tank and a device according to any one of the preceding claims, wherein the clamping collar can take on the neck of the tank a pre-assembled position and an assembled position. , the fastening means of the organ around the neck comprising deformable means, which are not deformed in the preassembled position and which are deformed in the assembled position, being kept deformed by the clamping collar. Note however that, according to another embodiment, the deformable means can be deformed in the preassembled position and not deformed in the assembled position, being held undeformed by the clamping collar. Preferably, the deformable means are elastic.
L'invention a également pour objet un procédé d'assemblage d'un tel dispositif de distribution sur un réservoir, au cours duquel on rapporte le dispositif sur le col du réservoir selon une première position dite pré-assemblée, on appuie sur le capot de protection, ce qui génère le coulissement du collier de serrage de façon que le dispositif de distribution prenne une seconde position dite assemblée. The subject of the invention is also a method for assembling such a dispensing device on a reservoir, during which the device is brought back onto the neck of the reservoir in a first position called pre-assembled. protection, which generates the sliding of the clamp so that the dispensing device takes a second position called assembly.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins dans lesquels : The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings in which:

L'embout de distribution 18 comporte une enveloppe 60, à l'intérieur de laquelle sont rapportés une embase 62, un cylindre 64 dans lequel est logé un second pointeau 66 formant clapet anti-retour, sous l'action d'un troisième ressort 68. Grâce à ce clapet anti-retour, on garantit que la buse de pulvérisation est étanche aux contaminants. L'enveloppe 60 comprend une surface d'appui 70, sous forme de deux ailettes, pour l'activation du dispositif par appui d'un utilisateur. L'enveloppe 60 comporte par ailleurs une bague 72 de retenue de l'embout, par coopération avec l'organe de fixation 24. A cet effet, la bague 72 porte, à son extrémité inférieure, une nervure annulaire 73 continue. L'enveloppe 60 comprend également une extrémité de pulvérisation 74, munie d'un orifice de pulvérisation 76 obturé par le pointeau 66 sous l'action du ressort 68. L'extrémité de pulvérisation 74 délimite, avec le cylindre 64, une chambre tourbillonnaire de distribution. L'embase 62 est une pièce rapportée à l'intérieur de l'enveloppe 60, par exemple par serrage, et comprenant une partie tubulaire 78, fixée sur la partie 54, par exemple par serrage autour de la partie 54. The dispensing nozzle 18 comprises a casing 60, inside which are attached a base 62, a cylinder 64 in which is housed a second needle valve 66 forming a non-return valve, under the action of a third spring 68 This non-return valve ensures that the spray nozzle is impervious to contaminants.

The base 62 is an insert inside the casing 60, for example by clamping, and comprising a tubular portion 78 fixed to the portion 54, for example by clamping around the portion 54.
L'organe de fixation 24 est en matière plastique. Il comprend, sur sa partie supérieure, une bague intérieure 80 de centrage de la pompe 16 sur le réservoir 12 et une bague extérieure 82. La bague extérieure 82 porte, sur son extrémité supérieure, des moyens 84 de retenue de l'embout de distribution 18, coopérant par butée avec l'enveloppe 60. Les moyens 84 comprennent un ou plusieurs ergots de retenue, formant une butée pour la nervure 73. La bague extérieure 82 porte par ailleurs sur sa surface extérieure une butée supérieure 83 de maintien du collier 22 dans sa configuration de pré-assemblage du dispositif, comme décrit plus bas. La bague intérieure 80 assure quant-à-elle un positionnement de la pompe 16 sur l'organe de fixation 24. Elle comprend par ailleurs une zone 86 de renfort de la patte élastique 42, illustrée sur la figure 3, évitant la déformation plastique de cette patte. L'organe 24 comporte en outre une jupe inférieure 87 portant des moyens 88 d'accrochage de l'organe autour du col 14, activables par coulissement du collier 22 par rapport à l'organe de fixation depuis une configuration de pré-assemblage vers une configuration d'assemblage. Les moyens d'accrochage 88, visibles sur la figure 4, comprennent des moyens élastiques qui constituent une butée inférieure 90 de maintien du collier de serrage 22 dans sa configuration de pré-assemblage, comme illustré sur la figure 1 , et qui sont déformables de telle sorte qu'ils peuvent être passés en force par le collier et qu'ils peuvent exercer une force de rappel sur le collier 22 lorsqu'il est en configuration d'assemblage, visible sur la figure 2. Cette force de rappel pousse les moyens 88 contre le collier 22 et assure ainsi un maintien du collier 22 en configuration d'assemblage. L'organe de fixation 24 comporte par ailleurs des ergots 89 permettant de maintenir l'organe 24 en position pré-assemblée sur le col du réservoir. The fixing member 24 is made of plastic. It comprises, on its upper part, an inner ring 80 for centering the pump 16 on the reservoir 12 and an outer ring 82.

The member 24 further comprises a lower skirt 87 carrying means 88 for hooking the member around the neck 14, which can be slidably actuated by the collar 22 relative to the fixing member from a pre-assembly configuration to a assembly configuration. The attachment means 88, visible in FIG. 4, comprise elastic means which constitute a lower abutment 90 for holding the clamp 22 in its pre-assembly configuration, as illustrated in FIG. 1, and which are deformable from so that they can be forced through the collar and they can exert a restoring force on the collar 22 when in assembly configuration, visible in Figure 2. This restoring force pushes the means 88 against the collar 22 and thus ensures a maintenance of the collar 22 in the assembly configuration. The fixing member 24 further includes lugs 89 for holding the member 24 in the pre-assembled position on the neck of the tank.
Le collier de serrage 22 est également réalisé en matière plastique. Il a une forme cylindrique de façon à pouvoir coulisser autour de la jupe inférieure 87 de l'organe 24. Le collier 22 comprend des moyens amovibles 92 d'encliquetage du capot 20, par exemple une rainure annulaire 92, coopérant avec une nervure annulaire du capot 20. Le collier 22 porte le capot 20 et est configuré de telle sorte qu'un appui sur le capot 20 est directement transmis au collier 22, de façon à le faire passer de sa configuration de pré-assemblage à sa configuration d'assemblage. A cet effet, le collier 22 comporte une portée 94 d'appui du capot 20, sous forme d'une collerette extérieure 94 faisant saillie du collier 22. The clamp 22 is also made of plastic. It has a cylindrical shape so as to slide around the lower skirt 87 of the member 24.

For this purpose, the collar 22 has a bearing surface 94 for supporting the cap 20, in the form of an external collar 94 projecting from the collar 22.
L'assemblage du dispositif 10 sur le réservoir 12 va à présent être décrit. The assembly of the device 10 on the reservoir 12 will now be described.
On assemble tout d'abord le dispositif 10, indépendamment du réservoir 12, par exemple dans un premier lieu, en l'assemblant selon une configuration de préassemblage. Plus précisément, on rapporte l'organe de fixation 24 et le collier de serrage 22 autour du corps de pompe 28, puis on assemble la partie fixe de la pompe 16, en disposant le piston, le tube 30 et le manchon 38 sur le corps de pompe 28, ainsi que la partie mobile de la pompe, en rapportant sur la partie fixe le ressort 40, le support 52 et les cylindres 44, 46 munis du pointeau 48 et du ressort 50. On rapporte ensuite l'embout de distribution 18 sur la pompe 16 et dans l'organe 24, d'une part en insérant la nervure 73 à l'intérieur de la bague 82, par passage en force des ergots 84, d'autre part en fixant l'embase 62 autour de la partie 54. On rapporte ensuite le capot 20 sur le collier de serrage 22. On obtient ainsi un dispositif en configuration de pré-assemblage, que l'on peut éventuellement transporter vers un second lieu, afin de le monter sur le réservoir 12, en position pré-assemblée, comme illustré sur la figure 1. The device 10 is first assembled independently of the reservoir 12, for example in a first place, by assembling it in a pre-assembly configuration. More specifically, the fixing member 24 and the clamping collar 22 are reported around the pump body 28, then the fixed part of the pump 16 is assembled, by placing the piston, the tube 30 and the sleeve 38 on the body pump 28, as well as the movable portion of the pump, by bringing back on the fixed part the spring 40, the support 52 and the cylinders 44, 46 provided with the needle 48 and the spring 50. The dispensing nozzle 18 is then reported. on the pump 16 and in the member 24, on the one hand by inserting the rib 73 inside the ring 82, by force passage of the lugs 84, on the other hand by fixing the base 62 around the part 54. The cover 20 is then brought back onto the clamping collar 22. This produces a device in pre-assembly configuration, which can optionally be transported to a second location, in order to mount it on the reservoir 12, in pre-assembled position, as shown in Figure 1.
Ensuite, le passage de la position pré-assemblée à la position assemblée illustrée sur la figure 2 est particulièrement simple. Il suffit d'appuyer sur le haut du capot 20, ce qui a pour effet de faire coulisser le collier 22, qui déforme les moyens 88 en coulissant, en les faisant plier vers l'intérieur, de telle sorte qu'ils forment une mâchoire autour du col du réservoir 12. Le collier 22 coulisse jusqu'à ce que son extrémité supérieure arrive en butée contre une surface horizontale de l'organe 24, comme on le voit sur le figure 2. On définit ainsi une position assemblée du dispositif 10 sur le réservoir 12, correspondant à une configuration assemblée dans laquelle le collier 22 est fixé de façon permanente par rapport à l'organe 24, du fait des frottements importants générés par la force de rappel des moyens d'accrochage 88 contre le collier 22. Next, the transition from the pre-assembled position to the assembled position illustrated in FIG. 2 is particularly simple. It suffices to press on the top of the cover 20, which has the effect of sliding the collar 22, which deforms the means 88 by sliding, by folding them inwards, so that they form a jaw around the neck of the reservoir 12. The collar 22 slides until its upper end abuts against a horizontal surface of the member 24, as seen in Figure 2. Thus defines an assembled position of the device 10 on the reservoir 12, corresponding to an assembled configuration in which the collar 22 is permanently fixed relative to the member 24, because of the high friction generated by the restoring force of the fastening means 88 against the collar 22 .
On comprend que le dispositif 10 est particulièrement intéressant s'il est utilisé avec du produit sans agent de conservation. En effet, la retenue de l'embout 18 par les moyens 84 assure une garantie supplémentaire que l'embout ne sera pas détaché du dispositif suite à une chute ou à une manipulation de l'utilisateur. Par ailleurs, l'utilisateur ne pourra pas démonter les moyens d'accrochage 88. Le dispositif 10 est particulièrement indiqué dans un système de type " airless ", sans reprise d'air. En effet, on utilise ce type de pompe dans le cas où il est important qu'aucune bactérie ne soit en contact avec le produit, et le dispositif 10 est un dispositif efficace pour éviter l'introduction de bactéries. La structure et le fonctionnement du dispositif 10 ne sont pas limités à ce qui est précédemment décrit. It is understood that the device 10 is particularly advantageous if it is used with the product without preservative. Indeed, the retention of the nozzle 18 by the means 84 provides an additional guarantee that the tip will not be detached from the device following a fall or manipulation of the user. Furthermore, the user will not be able to disassemble the fastening means 88. The device 10 is particularly indicated in an "airless" type system, without air intake. Indeed, this type of pump is used in the case where it is important that no bacteria is in contact with the product, and the device 10 is an effective device to prevent the introduction of bacteria. The structure and operation of the device 10 are not limited to what is previously described.
On notera par ailleurs que le dispositif de distribution 10 décrit ci-dessus pourrait avoir les mêmes fonctionnalités tout en étant fixé différemment sur le col du réservoir. En effet, l'organe de fixation pourrait être fixé, non pas selon le mode « snap-on », mais par sertissage ou par vissage. Dans ce cas, on utilise des pièces similaires, hormis le fait que le dispositif ne comprend pas de collier de serrage, le capot étant rapporté directement sur la bague extérieure de l'organe de fixation, et que l'organe de fixation comporte, à la place des moyens élastique d'accrochage sur le col, des moyens de fixation par sertissage ou par vissage. Note also that the dispensing device 10 described above could have the same functionality while being fixed differently on the neck of the tank. Indeed, the fastener could be fixed, not in the "snap-on" mode, but by crimping or screwing. In this case, similar parts are used, except that the device does not comprise a clamp, the cover being attached directly to the outer ring of the fastener, and that the fastener comprises, the place of the elastic fastening means on the neck, fastening means by crimping or screwing.
