Description

La présente invention concerne un organe de distribution tel qu'une pompe ou une valve ainsi qu'un procédé de montage d'un tel organe de distribution. Plus particulièrement, cet organe de distribution comprend un corps dans lequel coulisse un piston pour faire varier le volume d'une chambre de pompe ou de valve. Pour déplacer ce piston, il est en général prévu un poussoir qui relie le piston par l'intermédiaire d'une tige d'actionnement. D'autre part, il est connu d'utiliser une virole qui est engagée de préférence en force dans le corps : cette virole sert de bouchon étanche à l'extrémité supérieure du corps et définit une butée haute pour le piston en position de repos dans laquelle la chambre atteint son volume maximal. Le piston est ainsi sollicité contre la virole par un ressort de rappel. Il s'agit là d'une conception tout à fait classique pour une pompe ou une valve.The present invention relates to a distribution member such as a pump or a valve as well as a method of mounting such a device distribution. More particularly, this distribution member comprises a body in which a piston slides to vary the volume of a pump or valve. To move this piston, there is generally provided a pusher which connects the piston via an actuating rod. On the other hand, is known to use a ferrule which is preferably engaged in force in the body: this ferrule serves as a tight plug at the upper end of the body and defines a high stop for the piston in the rest position in which the chamber reaches its maximum volume. The piston is thus urged against the ferrule by a return spring. This is a completely classic design for a pump or a valve.

D'autre part, un organe de distribution classique comprend des moyens de fixation pour le fixer sur ou dans le col. Dans le cas présent, les moyens de fixation comprennent au moins un profil périphérique qui fait saillie radialement vers l'extérieur. Ce profil saillant est destiné à venir se loger dans un évidement formé dans une paroi interne d'un col de récipient. Il s'agit là d'une technique d'encliquetage à l'intérieur du col d'un récipient. Le ou les profils saillants peuvent être formés sur la paroi externe du corps ou sur la paroi externe d'une jupe qui entoure le corps de manière serrante et de préférence étanche.On the other hand, a conventional distribution member comprises means of fixing to fix it on or in the collar. In this case, the means of attachment include at least one peripheral profile which projects radially outwards. This projecting profile is intended to be housed in a recess formed in an inner wall of a container neck. This is a technique latching inside the neck of a container. The salient profile (s) can be formed on the outer wall of the body or on the outer wall of a skirt which tightly and preferably tightly surrounds the body.

Pour atteindre sa position finale d'encliquetage dans l'évidement du col, le ou les profils saillants doivent pouvoir se déplacer élastiquement radialement vers l'intérieur pour passer la section d'entrée du col de diamètre réduit qui est située juste au-dessus de l'évidement.To reach its final snap position in the neck recess, the projecting profile (s) must be able to move elastically radially inward to pass the reduced diameter neck entry section which is located just above the recess.

Un tel organe de distribution est décrit dans le document FR 2 792 295.Such a distribution member is described in document FR 2 792 295.

Il existe d'autre part une autre exigence liée à la conception des pompes ou valves modernes : en effet, il est préférable, que la pompe ou la valve présente une hauteur minimum au-dessus du col du récipient, ce qui impose d'engager le corps de l'organe de distribution le plus possible à l'intérieur du col du récipient. Il est donc avantageux d'engager le corps dans le col de sorte que son extrémité supérieure soit située environ au niveau de l'extrémité supérieure du col. Dans ce cas, la virole engagée en force dans le corps est également engagée à l'intérieur du col et peut s'étendre jusqu'au niveau du ou des profils saillants formés par les moyens de fixation. Etant donné que la virole est une pièce relativement rigide, puisqu'elle doit supporter la sollicitation du piston en position de repos, elle est pratiquement indéformable de sorte qu'elle peut gêner l'opération de fixation de la pompe à l'intérieur du col. Dans le document susmentionné, il est prévu que la virole ne soit mise en place définitivement qu'une fois les profils saillants engagés dans l'évidement du col.There is also another requirement related to the design of the pumps. or modern valves: indeed, it is preferable that the pump or the valve present a minimum height above the container neck, which requires engaging the body of the dispensing member as much as possible inside the neck of the container. It is therefore advantageous to engage the body in the neck so that its end upper is located approximately at the upper end of the neck. In this case, the ferrule engaged in force in the body is also engaged inside of the neck and may extend to the level of the projecting profile or profiles formed by the fixing means. Since the ferrule is a relatively rigid part, since it must withstand the stress of the piston in the rest position, it is practically undeformable so that it can interfere with the attachment of the pump inside the neck. In the aforementioned document, it is expected that the shell is not put in place definitively until the salient profiles are engaged in the neck recess.

La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un organe de distribution dont la virole, tout en remplissant sa fonction habituelle de bouchon étanche et de butée haute pour le piston, permet également une fixation aisée de l'organe de distribution dans le col d'un récipient formé avec un évidement d'encliquetage.The object of the present invention is to remedy the aforementioned drawbacks of the prior art by defining a distribution member including the ferrule, while fulfilling its usual function of tight plug and high stop for the piston, also allows easy attachment of the dispensing member in the neck of a container formed with a latching recess.

Les problèmes susmentionnés sont résolus par un organe de distribution, tel qu'une pompe ou une valve, comprenant un corps dans lequel coulisse un piston et dans lequel est engagée une virole, et des moyens de fixation comprenant au moins un profil périphérique qui fait saillie radialement vers l'extérieur, ledit profil saillant étant destiné à venir se loger dans un évidement formé dans une paroi interne d'un col de récipient, ledit profil saillant étant déplaçable élastiquement radialement vers l'intérieur pour venir se loger dans l'évidement du col en déformant élastiquement le corps radialement vers l'intérieur dans une zone de déformation, la virole étant hors de contact du corps dans cette zone de déformation. Ceci signifie que la virole ne s'étend pas jusqu'au niveau de la zone de déformation ou que la virole n'est pas en contact du corps au niveau de cette zone de déformation.The above problems are solved by a distributor, such as a pump or a valve, comprising a body in which slides a piston and in which a ferrule is engaged, and fixing means comprising at least one peripheral profile which projects radially towards the exterior, said projecting profile being intended to be housed in a recess formed in an internal wall of a container neck, said projecting profile being resiliently radially inwardly movable to accommodate the neck recess by elastically deforming the body radially towards inside in a deformation zone, the shell being out of contact with the body in this deformation zone. This means that the shell does not extend up to the level of the deformation zone or that the shell is not in contact of the body at this deformation zone.

De préférence, la virole s'étend axialement dans le corps jusqu'au niveau du profil saillant, un espace intermédiaire étant alors prévu entre le corps et la virole pour permettre au corps de se déformer radialement vers l'intérieur. Ceci est partiellement avantageux, car il est ainsi permis de satisfaire à l'exigence susmentionnée liée à la hauteur minimale de la pompe au-dessus du col.Preferably, the shell extends axially in the body up to the level of the projecting profile, an intermediate space then being provided between the body and the ferrule to allow the body to deform radially inward. This is partially advantageous, as it is thus permissible to meet the requirement mentioned above linked to the minimum height of the pump above the neck.

Ainsi, le ou les profils saillants et le corps peuvent se déformer librement de manière élastique vers l'intérieur dans cet espace intermédiaire sans être gênés par la virole rigide. La virole préserve cependant toutes ses fonctions initiales, à savoir celles de bouchon et de butée haute de repos pour le piston.Thus, the projecting profile (s) and the body can deform freely resiliently inward in this intermediate space without being hindered by the rigid ferrule. The shell retains all of its initial functions, however. know those of the plug and the upper rest stop for the piston.

Avantageusement, ledit espace intermédiaire est formé par un épaulement de la virole vers l'intérieur. En variante ou additionnellement, ledit espace intermédiaire est formé par une réduction de l'épaisseur de paroi de la virole.Advantageously, said intermediate space is formed by a shoulder from the shell inward. As a variant or additionally, said space intermediate is formed by a reduction in the wall thickness of the shell.

Selon une forme de réalisation pratique, la virole comprend une première section en contact serrant dans le corps et une seconde section au moins partiellement en éloignement du corps pour former l'espace intermédiaire. La première section est située juste à l'entrée du corps au-dessus du profil saillant alors que la seconde section réduite est située au niveau des profils saillants.According to a practical embodiment, the ferrule comprises a first section in tight contact in the body and at least a second section partially away from the body to form the intermediate space. The first section is located just at the entrance of the body above the protruding profile while the second reduced section is located at the level of the projecting profiles.

Selon une autre caractéristique, la virole comprend une bride d'appui en butée sur une extrémité du corps.According to another characteristic, the ferrule comprises a support flange in stop on one end of the body.

Selon un autre aspect de l'invention, les moyens de fixation comprennent une jupe qui s'étend autour du corps, le profil saillant étant formé sur une paroi externe de la jupe, un canal de refoulement étant formé entre la jupe et le corps pour permettre à du produit fluide de sortir du corps sous l'action du piston. Avantageusement, le corps est engagé dans la jupe avec un contact serrant étanche pour isoler entre eux le canal de refoulement.According to another aspect of the invention, the fixing means comprise a skirt which extends around the body, the projecting profile being formed on a wall external of the skirt, a delivery channel being formed between the skirt and the body to allow fluid to exit the body under the action of the piston. Advantageously, the body is engaged in the skirt with a tight contact waterproof to isolate the discharge channel from each other.

En variante, le profil saillant est formé par une paroi externe du corps.As a variant, the projecting profile is formed by an external wall of the body.

La présente invention prévoit également un procédé de fixation d'organe de distribution, tel qu'une pompe ou une valve, comprenant un corps dans lequel coulisse un piston et dans lequel est engagée une virole, et des moyens de fixation dans lesquels le corps est reçu, lesdits moyens de fixation comprenant au moins un profil périphérique qui fait saillie radialement vers l'extérieur, ledit profil saillant étant destinée à venir se loger dans un évidement formé dans une paroi interne d'un col de récipient, ledit profil saillant étant déplaçable élastiquement radialement vers l'intérieur pour venir se loger dans l'évidement du col en déformant élastiquement le corps radialement vers l'intérieur, ledit procédé comprenant l'étape d'exercer une pression suffisante sur les moyens de fixation pour amener les profils saillants dans l'évidement du col.The present invention also provides a method of organ fixation distribution, such as a pump or a valve, comprising a body in which slides a piston and in which is engaged a ferrule, and means for fixing in which the body is received, said fixing means comprising at at least one peripheral profile which projects radially outwards, said protruding profile being intended to be housed in a recess formed in a inner wall of a container neck, said projecting profile being movable elastically radially inward to be housed in the recess neck by elastically deforming the body radially inward, said process comprising the step of exerting sufficient pressure on the means of attachment to bring the protruding profiles into the neck recess.

Avantageusement, la virole est hors de contact de la zone de déformation du corps. De préférence, la virole s'étend axialement dans le corps jusqu'au niveau du profil saillant, un espace intermédiaire étant prévu entre le corps et la virole pour permettre au corps de se déformer radialement vers l'intérieur.Advantageously, the shell is out of contact with the deformation zone from the body. Preferably, the shell extends axially in the body up to level of the protruding profile, an intermediate space being provided between the body and the ferrule to allow the body to deform radially inward.

L'invention sera maintenant plus amplement décrite en référence à la figure unique qui est une vue en section transversale verticale à travers un organe de distribution selon l'invention monté sur un col de récipient.The invention will now be described more fully with reference to the single figure which is a vertical cross-sectional view through an organ dispenser according to the invention mounted on a container neck.

L'organe de distribution représenté sur la figure unique est une pompe, mais il aurait également pu s'agir d'une valve. La pompe, désignée dans son ensemble par la référence numérique 1, comprend un corps de pompe 2 définissant un fût cylindrique 20 dans lequel coulisse un piston 3 monté sur une tige d'actionnement 31 coiffé d'un poussoir 32. A son extrémité inférieure, le corps 2 définit une entrée sous la forme d'un manchon 23 avantageusement destiné à l'adaptation d'un tube plongeur qui s'étend à l'intérieur du réservoir jusqu'à son fond. A l'opposé, le corps 2 définit une extrémité supérieure 24 sous la forme d'un épaulement vers l'extérieur. Le piston 3 est sollicité par un ressort de rappel 7 dans une position de repos représentée sur la figure unique. Cette position de repos est fixée par une virole 4 engagée en force à l'intérieur du corps 2. Plus précisément, la virole 4 prend appui sur l'extrémité supérieure 24 du corps 20 au moyen d'une bride d'appui 43, et s'étend ensuite vers le bas à l'intérieur du corps 2 pour définir à son extrémité inférieure une butée 45 pour le piston 3. Il s'agit là d'une conception tout à fait classique pour une pompe ou une valve dans le domaine de la cosmétique, de la parfumerie ou encore de la pharmacie.The distribution member shown in the single figure is a pump, but it could also have been a valve. The pump, designated in its together by reference numeral 1, includes a pump body 2 defining a cylindrical barrel 20 in which slides a piston 3 mounted on a actuating rod 31 capped with a pusher 32. At its lower end, the body 2 defines an inlet in the form of a sleeve 23 advantageously intended for the adaptation of a dip tube which extends inside the tank to its bottom. In contrast, the body 2 defines an upper end 24 under the shape of an outward shoulder. The piston 3 is biased by a spring return 7 in a rest position shown in the single figure. This rest position is fixed by a ferrule 4 forcibly engaged inside the body 2. More specifically, the ferrule 4 bears on the upper end 24 of the body 20 by means of a support flange 43, and then extends downward to inside the body 2 to define at its lower end a stop 45 for the piston 3. This is a completely classic design for a pump or a valve in the field of cosmetics, perfumery or even pharmacy.

D'autre part, la pompe 1 est pourvue de moyens de fixation, ici sous la forme d'une bague 5 définissant une jupe sensiblement cylindrique 50 dans laquelle est engagé le corps de pompe 2. L'engagement du corps de pompe dans la jupe 50 est réalisé de manière serrante et étanche : en effet, la paroi externe 22 du fût 20 est en contact serrant étanche avec la paroi interne 52 de la jupe 50. La jupe 50 comprend une paroi externe 51 pourvue d'un ou de plusieurs profils saillants 53 qui peuvent se présenter sous la forme de bossages répartis sur la périphérie de la jupe ou encore sous la forme d'un cordon périphérique continu. Nous désignerons toutes ces variantes sous le terme de profil saillant 53. Comme on peut le voir sur la figure unique, le profil saillant 53 est engagé à l'intérieur d'un évidement 82 formé dans la paroi interne 81 d'un col 80. La position d'encliquetage finale est atteinte lorsque le profil saillant 53 est logé dans l'évidement 82 et lorsque la bague 5 vient en contact avec une collerette d'appui 54 sur l'extrémité supérieure 83 du col de récipient. On peut cependant remarquer que la paroi interne 81 du col 80 forme, au-dessus de l'évidement 82, une section de diamètre réduit : pour atteindre sa position d'encliquetage, le profil saillant 53 doit passer sur cette section de diamètre réduit et subir lors de ce passage une déformation élastique radiale vers l'intérieur. En général, le récipient peut être réalisé en verre ou en un plastique indéformable, alors que la bague 5 et le corps 2 peuvent être réalisés en un plastique plus déformable. Cependant, comme la jupe 50 est en contact du fût 20 du corps 2, la déformation élastique vers l'intérieur du profil saillant 53 a pour effet de déformer le fût 50 du corps 2 au niveau du profil saillant. La paroi interne 21 du fût 20 du corps 2 va donc subir momentanément et localement une déformation élastique vers l'intérieur jusqu'à ce que le profil saillant 53 vient se loger dans l'évidement 82 du col 80. Cette déformation s'effectue dans une zone 200 du corps située au droit des profils saillants 53.On the other hand, the pump 1 is provided with fixing means, here under the shape of a ring 5 defining a substantially cylindrical skirt 50 in which is engaged the pump body 2. The engagement of the pump body in the skirt 50 is produced in a tight and watertight manner: in fact, the external wall 22 of the barrel 20 is in tight sealing contact with the internal wall 52 of the skirt 50. The skirt 50 includes an outer wall 51 provided with one or more profiles projections 53 which may be in the form of bosses distributed over the periphery of the skirt or in the form of a continuous peripheral cord. We will designate all these variants under the term projecting profile 53. As we can see it in the single figure, the protruding profile 53 is engaged inside of a recess 82 formed in the internal wall 81 of a neck 80. The position final latching is reached when the protruding profile 53 is housed in the recess 82 and when the ring 5 comes into contact with a support flange 54 on the upper end 83 of the container neck. We can however note that the internal wall 81 of the neck 80 forms, above the recess 82, a reduced diameter section: to reach its latching position, the protruding profile 53 must pass over this section of reduced diameter and undergo during this passing a radial elastic deformation inward. In general, the container can be made of glass or a non-deformable plastic, while the ring 5 and the body 2 can be made of a more deformable plastic. However, as the skirt 50 is in contact with the barrel 20 of the body 2, the elastic deformation inwardly of the protruding profile 53 has the effect of deforming the barrel 50 of the body 2 at the protruding profile. The internal wall 21 of the barrel 20 of the body 2 therefore goes momentarily and locally undergo elastic deformation inward until the projecting profile 53 is received in the recess 82 of the neck 80. This deformation takes place in an area 200 of the body located at the level of the salient profiles 53.

D'autre part, on peut remarquer que la virole 4 est engagée dans le corps de pompe 2 jusqu'au niveau du profil saillant 53. Ceci provient du fait qu'il est aujourd'hui préférable, voire indispensable, de réduire la hauteur de la pompe au-dessus du col, et ainsi de faire pénétrer au maximum le corps de pompe 2 à l'intérieur du col. On peut aisément voir que la bride d'appui 43 de la virole 4 n'est située que très peu au-dessus de l'extrémité supérieure 83 du col 80. Par conséquent, la virole s'étend alors à l'intérieur du corps et vient jusqu'au niveau du profil saillant 53. On peut cependant imaginer d'autres formes de réalisation, dans lesquelles la virole ne s'étend pas jusqu'au niveau de la zone de déformation 200 du corps 2. Mais la forme de réalisation représentée sur la figure unique est préférée quant à la position de la virole par rapport aux profils saillants.On the other hand, we can notice that the ferrule 4 is engaged in the body pump 2 up to the level of the protruding profile 53. This is because it is today preferable, even essential, to reduce the height of the pump above the neck, and thus make the pump body 2 penetrate as much as possible. inside the collar. We can easily see that the support flange 43 of the ferrule 4 is located only very little above the upper end 83 of the neck 80. By therefore, the shell then extends inside the body and comes up to the level of the protruding profile 53. One can however imagine other embodiments, in which the shell does not extend to the level of the zone of deformation 200 of body 2. But the embodiment shown in the figure unique is preferred for the position of the shell relative to the profiles protruding.

Selon l'invention, pour permettre à la paroi interne 21 du corps de pompe 2 de se déformer élastiquement radialement vers l'intérieur sous l'effet de la déformation du profil saillant 53, il est prévu un espace intermédiaire 46 entre la paroi interne 21 du corps de pompe 2 et la virole 4. Cet espace intermédiaire 46 peut se présenter sous la forme d'un annulaire cylindrique, ou encore sous la forme de plusieurs évidements longitudinaux qui s'étendent sur la hauteur de la virole. On peut par exemple imaginer que la bague 5 forme six profils saillants 56 : on peut alors prévoir six espaces intermédiaires correspondants situés au droit de chaque de profils saillants. Cependant, selon une forme pratique, il est plus facile de former cet espace intermédiaire sous la forme d'un annulaire complet qui s'étend entre la virole et la paroi interne 21 de la paroi interne du corps de pompe 2. En prévoyant cet espace intermédiaire 46, il est possible d'engager le profil saillant 53 dans l'évidement 82 par déformation radiale vers l'intérieur sans pour autant nuire ou modifier la fonction de la virole 4 dont l'extrémité inférieure 45 sert toujours de butée haute pour le piston 3.According to the invention, to allow the internal wall 21 of the pump body 2 to deform elastically radially inwards under the effect of the deformation of the protruding profile 53, an intermediate space 46 is provided between the internal wall 21 of the pump body 2 and the ferrule 4. This intermediate space 46 may be in the form of a cylindrical annular, or alternatively in the form of several longitudinal recesses which extend over the height of the ferrule. One can for example imagine that the ring 5 forms six salient profiles 56: we can then provide six corresponding intermediate spaces located at right of each of salient profiles. However, in a practical form, it is easier to form this intermediate space in the form of a ring finger complete which extends between the shell and the internal wall 21 of the internal wall of the pump body 2. By providing this intermediate space 46, it is possible to engage the projecting profile 53 in the recess 82 by radial deformation towards the interior without affecting or modifying the function of the shell 4, of which the lower end 45 always serves as an upper stop for the piston 3.

Plus précisément, la virole 4 comprend en dessous de sa bride d'appui 43 une première section supérieure 41 engagée en contact serrant à l'intérieur du corps de pompe 2 au niveau de son extrémité supérieure 24 et une seconde section inférieure 47 au moins partiellement éloignée de la paroi interne 21 du corps et formant à son extrémité inférieure la butée haute 45 pour le piston 3. L'espace intermédiaire 46 peut être formé par un épaulement vers l'intérieur de la virole et/ou par une réduction de l'épaisseur de la paroi de la virole. Dans le cas représenté sur la figure unique, il s'agit d'un épaulement vers l'intérieur engendrant une réduction de l'épaisseur de paroi de la virole au niveau de sa seconde section inférieure 47. La première section supérieure 41 assure à elle seule l'ancrage solide de la virole 4 à l'intérieur du corps de pompe 2, alors que la seconde section inférieure 47 assure la butée haute 45 et permet le dégagement de l'espace intermédiaire 46.More specifically, the ferrule 4 comprises below its support flange 43 a first upper section 41 engaged in tight contact inside the pump body 2 at its upper end 24 and a second lower section 47 at least partially remote from the inner wall 21 of the body and forming at its lower end the upper stop 45 for the piston 3. The intermediate space 46 can be formed by an inward shoulder of the ferrule and / or by a reduction in the thickness of the wall of the ferrule. In the case shown in the single figure, it is an inward shoulder causing a reduction in the wall thickness of the ferrule at its second lower section 47. The first upper section 41 provides for it only the solid anchoring of the ferrule 4 inside the pump body 2, while the second lower section 47 provides the upper stop 45 and allows the release of the intermediate space 46.

Comme expliqué précédemment, la paroi externe 22 du fût 20 du corps de pompe 2 est engagée de manière serrant et étanche à l'intérieur de la jupe 50, c'est à dire contre sa paroi interne 52. Selon une autre caractéristique de l'invention, un canal de refoulement 25 est formé entre le fût 20 et la jupe 50 et s'étend sur la quasi-totalité de la hauteur du fût 20, et par conséquent également au niveau du profil saillant 53 et de l'espace 46. Ce canal de refoulement 25 communique avec la chambre de pompe par l'intermédiaire d'une entrée 26 et débouche à son extrémité supérieure 27 dans une autre chambre de clapet de sortie dont le volume est variable par le déplacement d'un organe de clapet mobile 6 monté coulissant à la fois dans une extension 201 du corps de pompe 20 et une douille de guidage 44 formée par la virole 4. L'organe de clapet mobile 6 est sollicité dans sa position de repos par le ressort de rappel 7 qui prend appui sous le poussoir 32. Au-delà du clapet de sortie, le produit parvient à un gicleur 55 qui permet la pulvérisation du produit fluide. Le gicleur 55 est reçu dans un logement 56 formé par la bague 5. On peut dire que la bague 5 forme au-dessus de la collerette d'appui 54 une douille 57 dans laquelle est ménagé le logement 56 pour le gicleur 55. La douille 57 peut être revêtue ou coiffée d'une frette d'habillage 9, de préférence réalisée en métal.As explained above, the external wall 22 of the barrel 20 of the body of pump 2 is tightly and tightly engaged inside the skirt 50, that is to say against its internal wall 52. According to another characteristic of the invention, a delivery channel 25 is formed between the barrel 20 and the skirt 50 and extends over almost the entire height of the bole 20, and therefore also at the level of the projecting profile 53 and the space 46. This delivery channel 25 communicates with the pump chamber via an inlet 26 and opens at its upper end 27 into another valve chamber outlet whose volume is variable by the movement of a valve member mobile 6 slidably mounted both in an extension 201 of the pump body 20 and a guide sleeve 44 formed by the ferrule 4. The movable valve member 6 is biased in its rest position by the return spring 7 which is supported under pusher 32. Beyond the outlet valve, the product reaches a nozzle 55 which allows the spraying of the fluid product. The nozzle 55 is received in a housing 56 formed by the ring 5. It can be said that the ring 5 forms above from the support flange 54 a socket 57 in which the housing is formed 56 for the nozzle 55. The sleeve 57 can be coated or topped with a hoop covering 9, preferably made of metal.

Pour la fixation de la pompe dans le col 80 du récipient, c'est à dire l'engagement des profils saillants 53 dans l'évidement 82, une pression suffisante P peut être appliquée sur la bague 5, ou plus précisément sur la douille 57 ou sur la frette 9, s'il y en a une.For fixing the pump in the neck 80 of the container, i.e. the engagement of the protruding profiles 53 in the recess 82, sufficient pressure P can be applied to the ring 5, or more precisely to the socket 57 or to fret 9, if there is one.

On peut d'ailleurs utiliser ce procédé de fixation par appui sur la bague de fixation 5, même si la virole 4 ne s'étend pas jusqu'au niveau des profils saillants 53. Bien entendu, il faut que les profils saillants 53 puissent être déplacés vers l'intérieur sans être gênés par la virole, ce qui est le cas lorsqu'un espace intermédiaire est ménagé entre le corps de pompe 2 et la virole 4.We can also use this fixing method by pressing on the ring attachment 5, even if the ferrule 4 does not extend to the level of the projecting profiles 53. Of course, the protruding profiles 53 must be able to be moved towards the interior without being obstructed by the ferrule, which is the case when a space intermediate is formed between the pump body 2 and the ferrule 4.

Il ne s'agit là que d'une forme de réalisation particulière qui ne limite en rien la présente invention dont l'esprit réside dans le fait que la virole ne puisse pas empêcher la libre déformation du corps vers l'intérieur lors du montage de la pompe dans un col de récipient. Un espace intermédiaire réalisé entre la virole et le corps de pompe pour permettre la déformation radiale vers l'intérieur du corps de pompe sous l'effet de la déformation du profil saillant pour parvenir dans l'évidement formé par le col du récipient est une forme de réalisation préférée.This is only a particular embodiment which does not limit in nothing the present invention whose spirit lies in the fact that the shell can not not prevent the free deformation of the body inwards when mounting the pump in a container neck. An intermediate space created between the shell and the pump body to allow the radial deformation towards the inside of the body pump under the effect of the deformation of the protruding profile to reach the recess formed by the neck of the container is a preferred embodiment.
