- the trim band comprises hooking means cooperating with abutment means formed by the ring to define together means for axially retaining the band on the ring.
- the document EP 1 270 434 discloses a fastener of this type in which the lower end of the hoop is hemmed inwardly so as to define an upwardly directed internal shoulder. This internal shoulder is intended to engage below the fixing ring which forms at this location stop means.
- the axial retaining means of the hoop on the ring are therefore defined by the internal shoulder of the hemmed end of the hoop in cooperation with the lower end of the ring, or more precisely the end edge of the fixing ring.
- the inner shoulder of the hoop is perfectly annular, so as to define a circle that extends in a single plane. It is the same for the lower end of the fixing ring, which also defines a circle extending in a single plane.
- the engagement of the internal shoulder just below the lower end of the ring defines a single axial position of locking the hoop on the ring.
- the disadvantage with the document fixing device EP 1 270 434 is that there is no freedom or modularity in the axial positioning of the hoop relative to the ring. Indeed, it is sometimes useful to be able to arrange the hoop axially relative to the ring depending on the configuration of the container on which the fastening device is to be mounted. More specifically, the hoop must generally come with its lower end resting on the container, so as to create a kind of continuity between the container and the fixing device. Consequently, it is sometimes necessary to depress the ring more or less on the ring, which amounts to modifying the axial position of the band on the ring.
- the object of the present invention is to overcome the aforementioned drawbacks of the prior art by defining a fixing device whose cladding band may be arranged and locked axially with respect to the ring at different offset axial positions.

- the internal shoulder is formed by a hemming of the hoop inwardly at its lower end.
- the abutment means comprise at least one abutment zone oriented downwards.
- the fixing ring comprises a substantially cylindrical skirt engaged around the neck, the skirt defining an outer wall comprising a plurality of axially offset abutment zones.
- the stop zones are formed by the downwardly directed lower ends of axial longitudinal ribs which extend vertically projecting radially from the outer wall of the skirt, the lower ends of the ribs being located at axially offset.
- the shoulder of the hoop has a crenellated profile defining axially offset gripping elements.
- the castellated profile defines slots of different heights and / or depths.
- the two embodiments can be implemented cumulatively in one and the same fastening device. However, it is best to implement them separately. It may also be noted that the axially offset gripping elements, whether formed by the hoop or by the ring, do not give rise to any difficulties of production or manufacture, with respect to the device for fixing the document EP-1 270 434 . Indeed, the alzration of the hemmed portion of the hoop is very easy to achieve. As for the molding of the ribs on the skirt, it does not cause any technical difficulty.
- the ring comprises a protruding preassembly flange with which the fastening means of the hoop come into engagement in the pre-assembled position.

- the already pre-assembled cover band can be pressed axially up and down on the ring to lock it engaged around the neck.
- the invention also defines a fluid dispenser comprising a container, a dispensing member such as a pump or a valve and a fixing device as defined above.
- the fixing device according to the invention is associated with a dispensing member, in this case a pump 4.
- a valve can very well be implemented in place of the pump.
- the fixing device associated with the pump is mounted on a container 3 which defines an opening, advantageously in the form of a neck 31.
- the neck 31 extends upwards from the body of the container, which forms in its upper part a shoulder 35.
- the neck 31 thus projects from this shoulder 35.
- the neck 31 comprises an outer peripheral reinforcement forming a flange 32 facing downwards.
- This flange 32 serves conventionally to the fastening of the fixing device, as will be seen below.
- the neck 31 also comprises an upper annular edge 33 and an inner wall 34 which defines the opening of the container.
- This container may be made of any suitable material, such as glass, plastic or metal.
- the dispensing member designated as a whole by the reference numeral 4, comprises a body 41 provided with a retaining flange 42 at its upper end.
- the distribution member 4 comprises also an actuating rod 43 which is movable back and forth against a return spring inside the body 41. This is a quite conventional design for a pump or a pump. valve in the fields of pharmacy, perfumery, or cosmetics.
- the fixing device serves to fix or hold the dispensing member 4 in the opening of the neck 31, with the actuating rod 43 projecting upwards from the neck. Once in place, the dispensing member receives a dispensing head which is mounted on the free upper end of the actuating rod 43, but this is not shown.

- the skirt 11 extends downwardly from an annular plate 15 which serves to compress a neck seal 5 on the upper annular end 33 of the neck.
- the crushing of the gasket 5 is obtained by the traction exerted by the skirt 11, the fastening means 12 of which are forced to be housed under the flange 32.
- This is also a quite conventional design for a bushing. fixation in the fields of cosmetics, perfumery or pharmacy.
- the fixing ring forms a receiving housing 17 in which is received the flange 42 formed by the body 41 of the dispensing member 4.
- the flange 42 may for example be received by latching.
- the detent housing 17 also forms a central passage 18 through which the actuating rod 43 extends.
- This general design of fixing ring is common to both embodiments. It allows a stable maintenance of the dispensing member 4, an effective situation on the neck 31.
- the attachment can be provided only by the ring.
- the skirt is split, the final fixing is obtained by the establishment of the trim band, as will be seen below.
- the present invention applies to both cases, namely continuous skirt or split skirt.
- the hoop 2 comprises a substantially cylindrical body 21 which extends at its upper end by a reentrant flap 26 which defines a large opening passage. At its opposite lower end, the hoop 2 comprises a thinned portion 22 whose wall thickness is less than that of most of the body 21. The difference in wall thickness between the body 21 and the thinned portion 22 is visible in the form of an internal recess 212 which extends over the entire inner periphery of the hoop.
- the lower end of the hoop is formed by an edge 23 which results from the hemming of a portion 24 of the hoop inwardly.
- This hemmed portion 24, which originally extended in the extension of the thinned portion 22 has been hemmed inward by a well-known hemming process.
- the lower edge 23 thus makes the junction between the thinned portion 22 and the inner hemmed portion 24.
- the free end of the hemmed portion 24 forms a shoulder 251 which is oriented upwards, that is to say in the direction of the returning flap 26.
- the shoulder 251 is thus oriented substantially opposite the recess 212, as can be seen in FIG. figure 2 .
- An annular housing is thus created in the inner wall of the hoop between the recess 212 and the shoulder 25. This design of hoop clothing is common to both embodiments.
- the fixing ring 1, the hoop 2, the container neck 31 and the dispenser member 4 all have a certain longitudinal axial symmetry along an axis X visible on the figures 1 and 6 .
- the dispensing member 4 is first engaged axially from below to the inside of the receiving housing 17 formed by the ring 1. Then, the ring 2 with its latched distribution 4 is reported axially from above on the container neck 31 until its fastening means 12 engage under the flange 32. Finally, the trim band 2 is axially reported from top to bottom on the fixing ring 1, so as to engage the outer wall of the skirt 11.
- the lower end or lower edge 23 of the hoop 2 abuts or is close to the shoulder 35 formed by the container 3. It is indeed desired that the hoop comes into contact with the shoulder 35 for aesthetic reasons .
- the fixing ring 1 is no longer visible, since the actuating rod 43 is still capped by the dispensing head which surrounds the hoop 2 or is housed inside the hoop 2 .
- the shoulder 25 of the hemmed portion 24 forms hooking means which cooperate with abutment means formed by the ring 2.
- abutment means may for example be formed by the lower end 13 of the skirt 11.
- the attachment means and the abutment means together define axial retention means which make it possible to block the hoop on the ring. It is thus no longer possible to remove the hoop from the ring, which implies that the ring 2 can no longer be removed from the container neck.
- the fixing of the dispensing member 4 on the container neck is permanent and inviolable.
- the axial retention means of the hoop on the ring make it possible to arrange the hoop on the ring in several distinct offset axial positions.
- the band 2 can be engaged on the ring with its lower edge 23 which extends more or less downwards from the lower end of the skirt 11. This allows to have and block the ring on the ring with the lower edge 23 of the collar in contact with the shoulder 35 of the container 3. And this, regardless of the height of the neck 31.
- the axial retention means thus comprise several mutual engagement elements which define axial engagement positions distinct from the band on the ring. These gripping elements can be formed either by the hoop or by the ring. These gripping elements make it possible to define determined axial positions of locking of the hoop relative to the ring as a function of the physiognomy of the container neck.
- the mutual engagement elements are formed by the trim band 2.
- the shoulder 25 of the hemmed portion 24 of the trim band has a serrated profile thus defining height and height slots. different depths.
- the hemmed portion 24 defines three crenellated heights 251, 253 and 254 separated by slot bottoms 252 at the same axial height.
- the slot vertices 251, 253 and 254 are located at different axial heights.
- the slot vertices and the slot bottoms define arcuate segments which are connected by radial segments 241, 243 and 244 of varying heights.
- the shoulder 25 formed by the hemmed portion 24 here defines four interlocking elements formed by the crestal peaks 251, 253 and 254 and the crestal bottoms 252.
- Each of these engagement elements is adapted to abut against the lower end 13 of the skirt 11, as can be seen on the figure 2 with the slot apex 251. If the container neck had been made more stubby or short, the shoulder 25 would have been located a little higher, and the slot apex 251 would not have been able to come into abutment. below the end 13. In contrast, the other crest 253 then would have filled the hooking function in abutment under the lower end 13. And if the collar was even more stocky, it is the niche bottom 252 which would abut under the lower end 13.
- the trim band 2 can be hooked under the ring 1 at different offset axial positions. This allows to hang the band under the ring regardless of the appearance of the container neck. Instead of the lower end 13 of the skirt 11, any other abutment zone formed by the ring 1 can be provided.
- the lower end 13 can abut against the slots because the ring, made of plastic material, always tends to deform or flow outwardly.
- the fixing ring 1 is also provided with a protruding pre-assembly peripheral flange 16 which protrudes radially outwards at the plate 15 at the upper end of the skirt 11.
- This flange 16 also serves to the attachment of the trim band 2 when the latter is not yet permanently engaged around the skirt 11.
- the fixing ring 1 can be mounted on a container neck, because the skirt 11 is not yet prevented from deforming radially outwardly by the engagement of the trim band 2.
- the hoop covering 2 is integral with the fixing ring 1 and constitutes, together with the ring, an unmountable unitary entity.
- the projecting flange 16 can engage with the shoulder 25 formed by the hemmed portion 24 or more precisely with any crenel formed by the crenellated profile of the shoulder. On the Figures 3 and 4 it is the crestal bottom 252 which is engaged with the projecting flange 16.
- the cover band 2 may be identical to that of the first embodiment, or alternatively, the hemmed portion 24 of the band may have a continuous internal shoulder 25, that is to say, devoid of crenellated profile.
- the skirt 11, which is split here is provided with several series of vertical longitudinal ribs 14 which extend downwards from the projecting flange 16.
- Each series of ribs here comprises three ribs of different heights.
- the fixing ring here comprises six skirt segments separated by six slots 111, the ring is provided with six series of three ribs of different heights.
- the ribs define lower abutment ends 141, 142 and 143 which are disposed at different offset axial heights.
- Each rib end thus defines abutment means oriented downwards, that is to say in the direction of the shoulder 25 of the hemming portion 24 which extends upwards.
- the shoulder 25 is housed just below the abutment end 141 of the longest rib.
- the series of ribs of different heights constitute mutual engagement elements for arranging and locking the hoop relative to the ring in offset axial positions.
- the shoulder 25 of the hemmed portion 24 can engage under the projecting flange 16 to preposition the trim band 2 on the fixing ring.
- the hoop 2 in which it has no hemmed portion 24, but forms a peripheral internal recess 24 'which defines a lower abutment edge 25' which can fulfill the same function as the shoulder 25.
- the abutment zone formed by the ring can thus abut on this lower edge.
- the hoop does not need to have an upper wall thickness below the lower edge because the The abutment zone formed by the ring will flow in the recess due to the creep properties of the plastic material constituting the ring.
- the retaining means at the upper part of the skirt and the hoop.
- the ring is preferably made of plastic and the hoop can be made of metal or plastic.
- the hoop may engage the ring at a location other than its free lower end.
- the trim band 2 is hooked and locked in axial positions which may vary for example depending on the appearance of the container neck.

Description
La présente invention concerne un dispositif de fixation pour fixer un organe de distribution, tel qu'une pompe ou une valve, sur un col de récipient. L'invention concerne également un distributeur de produit fluide comprenant un récipient, un organe de distribution tel qu'une pompe ou une valve, et un dispositif de fixation selon l'invention. Il est en effet connu dans de nombreux domaines techniques, comme par exemple ceux de la parfumerie, de la cosmétique, ou encore de la pharmacie, d'utiliser des distributeurs de produit fluide sous la forme d'un récipient associé à une pompe ou une valve fixée sur l'ouverture du récipient. Par actionnement de la pompe ou de la valve, du produit fluide dosé ou non est distribué. Dans ce genre de distributeur de produit fluide, il est essentiel que la pompe ou la valve soit fixée de manière stable et étanche sur l'ouverture du récipient. Pour cela, il est conventionnel d'utiliser un dispositif de fixation qui maintient la pompe ou la valve, et qui est pourvu de moyens de fixation sur l'ouverture du récipient. Ces moyens de fixation peuvent utiliser des techniques diverses, comme par exemple le vissage, le sertissage, le collage ou encore des techniques d'encliquetage ou d'accrochage.The present invention relates to a fastening device for fixing a dispensing member, such as a pump or a valve, on a container neck. The invention also relates to a fluid dispenser comprising a container, a dispensing member such as a pump or a valve, and a fixing device according to the invention. It is indeed known in many technical fields, such as those of perfumery, cosmetics, or even pharmacy, to use fluid dispensers in the form of a container associated with a pump or a pump. valve attached to the opening of the container. By actuation of the pump or the valve, the fluid product dosed or not is dispensed. In this type of fluid dispenser, it is essential that the pump or valve is stably and tightly secured to the opening of the container. For this, it is conventional to use a fixing device which holds the pump or the valve, and which is provided with fixing means on the opening of the container. These fastening means may use various techniques, such as screwing, crimping, gluing or latching or latching techniques.
Un mode de réalisation bien connu pour un descriptif de fixation met en oeuvre une bague de fixation comprenant les moyens de fixation sur le col du récipient et une frette d'habillage engagée axialement de haut en bas autour de la bague. Dans le cas de la présente invention, la frette d'habillage comprend des moyens d'accrochage coopérant avec des moyens de butée formés par la bague pour définir ensemble des moyens de retenue axiale de la frette sur la bague. Le document
L'inconvénient avec le dispositif de fixation du document
La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un dispositif de fixation dont la frette d'habillage peut être disposée et bloquée axialement par rapport à la bague en des positions axiales distinctes décalées.The object of the present invention is to overcome the aforementioned drawbacks of the prior art by defining a fixing device whose cladding band may be arranged and locked axially with respect to the ring at different offset axial positions.
Pour atteindre ce but, la présente invention propose un dispositif de fixation pour fixer un organe de distribution, tel qu'une pompe ou une valve, sur un col de récipient, le dispositif comprenant une bague de fixation comprenant des moyens de fixation sur le col de récipient et des moyens de butée, et une frette d'habillage engagée axialement de haut en bas autour de la bague, la frette comprenant des moyens d'accrochage coopérant avec les moyens de butée pour définir ensemble des moyens de retenue axiale de la frette sur la bague, caractérisé en ce que les moyens de retenue comprennent plusieurs éléments de prise mutuelle définissant des positions d'engagement axiales distinctes de la frette sur la bague. Tout comme dans le document précité de l'art antérieur, la frette d'habillage est toujours accrochée sur la bague, mais cet accrochage peut se faire en différents endroits axialement décalés. Les éléments de prise mutuelle permettant le décalage axial de l'accrochage peuvent être formés soit par la frette soit par la bague, ou les deux à la fois.To achieve this object, the present invention provides a fastening device for fixing a dispensing member, such as a pump or a valve, on a container neck, the device comprising a fixing ring comprising fastening means on the neck. container and stop means, and a trim band engaged axially from top to bottom around the ring, the ring comprising fastening means cooperating with the stop means for together defining means for axially retaining the band on the ring, characterized in that the retaining means comprise a plurality of mutual engagement elements defining axial engagement positions separate from the band on the ring. As in the aforementioned document of the prior art, the trim band is still attached to the ring, but this attachment can be done in different axially offset locations. The mutual engagement elements allowing the axial offset of the attachment can be formed either by the hoop or by the ring, or both at once.
Selon une forme de réalisation intéressante, la frette comprend une extrémité supérieure et une extrémité inférieure destinée à venir en appui sur le récipient, les moyens d'accrochage étant formés par un épaulement interne orienté vers le haut et avantageusement défini à proximité de l'extrémité inférieure. Avantageusement, l'épaulement interne est formé par un ourlage de la frette vers l'intérieur au niveau de son extrémité inférieure.According to an interesting embodiment, the hoop comprises an upper end and a lower end intended to bear against the container, the attachment means being formed by an internal shoulder oriented upwards and advantageously defined near the end. lower. Advantageously, the internal shoulder is formed by a hemming of the hoop inwardly at its lower end.
Selon un autre aspect de l'invention, les moyens de butée comprennent au moins une zone de butée orientée vers le bas.According to another aspect of the invention, the abutment means comprise at least one abutment zone oriented downwards.
Selon une première forme de réalisation pratique, il est prévu plusieurs zones de butée disposées en des positions axiales différentes, les différentes zones de butée définissant les dents de prise. Avantageusement, la bague de fixation comprend une jupe sensiblement cylindrique engagée autour du col, la jupe définissant une paroi externe comprenant plusieurs zones de butée décalées axialement. De préférence, les zones de butée sont formées par les extrémités inférieures orientées vers le bas de nervures longitudinales axiales qui s'étendent verticalement en faisant saillie radialement par rapport à la paroi externe de la jupe, les extrémités inférieures des nervures étant situées en des positions axialement décalées.According to a first practical embodiment, there are several stop zones disposed in different axial positions, the different stop zones defining the setting teeth. Advantageously, the fixing ring comprises a substantially cylindrical skirt engaged around the neck, the skirt defining an outer wall comprising a plurality of axially offset abutment zones. Preferably, the stop zones are formed by the downwardly directed lower ends of axial longitudinal ribs which extend vertically projecting radially from the outer wall of the skirt, the lower ends of the ribs being located at axially offset.
Selon un autre mode de réalisation avantageuse, l'épaulement de la frette présente un profil crénelé définissant des éléments de prise axialement décalés. Avantageusement, le profil crénelé définit des créneaux de hauteurs et/ou profondeurs différentes.According to another advantageous embodiment, the shoulder of the hoop has a crenellated profile defining axially offset gripping elements. Advantageously, the castellated profile defines slots of different heights and / or depths.
Il est à noter que les deux formes de réalisation peuvent être mises en oeuvre cumulativement dans un seul et même dispositif de fixation. Toutefois, il est préférable de les mettre en oeuvre séparément. On peut également noter que les éléments de prise axialement décalés, qu'ils soient formés par la frette ou par la bague, n'engendrent pas de difficultés de réalisation ou de fabrication, par rapport au dispositif de fixation du document
Selon une autre caractéristique intéressante de l'invention, la bague comprend une collerette saillante de prémontage avec laquelle les moyens d'accrochage de la frette viennent en prise en position prémontée. La position de prémontage, dans laquelle la frette n'est pas complètement engagée sur la bague, est utile notamment lors du transport, du stockage et de la manipulation du dispositif de fixation. En effet, cette collerette saillante permet de maintenir la frette sur la bague de sorte qu'ils ne forment ensemble plus qu'une seule unité indémontable. Lors de la mise en place du dispositif de fixation sur un récipient, la bague et la frette peuvent être manipulées comme s'il ne s'agissait que d'une seule pièce. Dès que la bague de fixation a été montée sur le col du récipient, la frette d'habillage déjà prémontée peut être enfoncée axialement de haut en bas sur la bague pour la bloquer en prise autour du col.According to another advantageous characteristic of the invention, the ring comprises a protruding preassembly flange with which the fastening means of the hoop come into engagement in the pre-assembled position. The pre-assembly position, in which the hoop is not completely engaged on the ring, is useful in particular during transport, storage and handling of the fixing device. Indeed, this protruding flange makes it possible to maintain the hoop on the ring so that they together form only one unmountable unit. When placing the fastener on a container, the ring and the hoop can be manipulated as if it were only one piece. As soon as the fixing ring has been mounted on the neck of the container, the already pre-assembled cover band can be pressed axially up and down on the ring to lock it engaged around the neck.
L'invention définit également un distributeur de produit fluide comprenant un récipient, un organe de distribution tel qu'une pompe ou une valve et un dispositif de fixation tel que définit ci-dessus.The invention also defines a fluid dispenser comprising a container, a dispensing member such as a pump or a valve and a fixing device as defined above.
L'invention sera maintenant 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 now be further described with reference to the accompanying drawings, giving by way of non-limiting example two embodiments of the invention.

Dans les deux modes de réalisation représentés sur les figures, le dispositif de fixation selon l'invention est associé à un organe de distribution, en l'occurrence une pompe 4. Toutefois, une valve peut très bien être mise en oeuvre à la place de la pompe. D'autre part, le dispositif de fixation associé à la pompe est monté sur un récipient 3 qui définit une ouverture, avantageusement sous la forme d'un col 31. Le col 31 s'étend vers le haut à partir du corps du récipient, qui forme dans sa partie supérieure un épaulement 35. Le col 31 fait donc saillie à partir de cet épaulement 35. Le col 31 comprend un renfort périphérique externe formant un rebord 32 orienté vers le bas. Ce rebord 32 sert de manière conventionnelle à l'accrochage du dispositif de fixation, comme on le verra ci-après. Le col 31 comprend également un bord annulaire supérieur 33 ainsi qu'une paroi interne 34 qui définit l'ouverture du récipient. Il s'agit là d'une conception tout à fait conventionnelle pour un récipient servant à contenir un produit fluide dans les domaines de la parfumerie, de la cosmétique, ou encore de la pharmacie. Ce récipient peut être réalisé en n'importe quel matériau approprié, comme par exemple le verre, le plastique ou le métal.In the two embodiments shown in the figures, the fixing device according to the invention is associated with a dispensing member, in this case a
L'organe de distribution, désigné en son ensemble par la référence numérique 4, comprend un corps 41 pourvu d'une collerette de maintien 42 au niveau de son extrémité supérieure. L'organe de distribution 4 comprend également une tige d'actionnement 43 qui est déplaçable en va et vient à l'encontre d'un ressort de rappel à l'intérieur du corps 41. Il s'agit là d'une conception tout à fait classique pour une pompe ou une valve dans les domaines de la pharmacie, la parfumerie, ou de la cosmétique.The dispensing member, designated as a whole by the
Le dispositif de fixation sert à fixer ou maintenir l'organe de distribution 4 dans l'ouverture du col 31, avec la tige d'actionnement 43 faisant saillie vers le haut à partir du col. Une fois en place, l'organe de distribution reçoit une tête de distribution qui est montée sur l'extrémité supérieure libre de la tige d'actionnement 43, mais ceci n'est pas représenté. Avantageusement, l'organe de distribution 4 peut également être pourvu d'un tube plongeur qui s'étend à l'intérieur du récipient 3 pour prélever le produit fluide.The fixing device serves to fix or hold the dispensing
Dans les deux modes de réalisation représentés sur les figures, le dispositif de fixation comprend deux éléments constitutifs, à savoir une bague de fixation 1 et une frette d'habillage 2.In the two embodiments shown in the figures, the fixing device comprises two constituent elements, namely a fixing
Dans les deux modes de réalisation des figures, la bague de fixation 1 comprend une jupe périphérique sensiblement cylindrique 11 qui est pourvue intérieurement de moyens de fixation 12 qui peuvent se présenter sous la forme d'un cordon d'encliquetage continu ou de têtes d'encliquetage ponctuelles. Les moyens de fixation 12 font saillie radialement vers l'intérieur à partir de la paroi interne de la jupe 11. Les moyens de fixation 12 sont destinés à venir en prise en dessous du rebord 32 formé par le col 31 du récipient 3, comme on peut le voir très clairement sur les
La jupe 11 s'étend vers le bas à partir d'un plateau annulaire 15 qui sert à comprimer un joint de col 5 sur l'extrémité annulaire supérieure 33 du col. L'écrasement du joint 5 est obtenu par la traction exercée par la jupe 11 dont les moyens de fixation 12 sont contraints de se loger sous le rebord 32. Il s'agit là également d'une conception tout à fait classique pour une bague de fixation dans les domaines de la cosmétique, de la parfumerie ou la pharmacie.The
Au-delà de ce plateau annulaire 15, la bague de fixation forme un logement de réception 17 dans lequel est reçue la collerette 42 formée par le corps 41 de l'organe de distribution 4. La collerette 42 peut par exemple être reçue par encliquetage. Le logement d'encliquetage 17 forme également un passage central 18 à travers lequel s'étend la tige d'actionnement 43.Beyond this
Cette conception générale de bague de fixation est commune aux deux modes de réalisation. Elle permet un maintien stable de l'organe de distribution 4, une situation efficace sur le col 31. Lorsque la jupe 11 est continue, la fixation peut être assurée uniquement par la bague. En revanche, lorsque la jupe est fendue, la fixation définitive est obtenue par la mise en place de la frette d'habillage, comme on le verra ci-après. La présente invention s'applique aux deux cas, à savoir jupe continue ou jupe fendue.This general design of fixing ring is common to both embodiments. It allows a stable maintenance of the dispensing
Dans les deux modes de réalisation, la frette 2 comprend un corps sensiblement cylindrique 21 qui se prolonge à son extrémité supérieure par un rabat rentrant 26 qui définit une grande ouverture de passage. A son extrémité inférieure opposée, la frette 2 comprend une partie amincie 22 dont l'épaisseur de paroi est inférieure à celle de la majeure partie du corps 21. La différence d'épaisseur de paroi entre le corps 21 et la partie amincie 22 est visible sous la forme d'un décrochement interne 212 qui s'étend sur toute la périphérie interne de la frette.In both embodiments, the
L'extrémité inférieure de la frette est formée par un bord 23 qui résulte de l'ourlage d'une partie 24 de la frette vers l'intérieur. Cette partie ourlée 24, qui s'étendait originellement dans le prolongement de la partie amincie 22 a été ourlée vers l'intérieur par un procédé d'ourlage bien connu. Le bord inférieur 23 réalise ainsi la jonction entre la partie amincie 22 et la partie intérieure ourlée 24. L'extrémité libre de la partie ourlée 24 forme un épaulement 251 qui est orienté vers le haut, c'est-à-dire en direction du rabat rentrant 26.The lower end of the hoop is formed by an
L'épaulement 251 est ainsi orienté sensiblement en regard du décrochement 212, comme on peut le voir sur la
La bague de fixation 1, la frette 2, le col de récipient 31 et l'organe de distribution 4 présentent tous une certaine symétrie axiale longitudinale le long d'un axe X visible sur les
Dans les deux modes de réalisation, l'épaulement 25 de la partie ourlée 24 forme des moyens d'accrochage qui coopèrent avec des moyens de butée formés par la bague 2. Ces moyens de butée peuvent par exemple être formés par l'extrémité inférieure 13 de la jupe 11. Les moyens d'accrochage et les moyens de butée définissent ensemble des moyens de retenue axiale qui permettent de bloquer la frette sur la bague. Il n'est ainsi plus possible de retirer la frette de la bague, ce qui implique que la bague 2 ne peut plus être retirée du col de récipient. Ainsi, la fixation de l'organe de distribution 4 sur le col de récipient est définitive et inviolable.In both embodiments, the
Selon l'invention, les moyens de retenue axiale de la frette sur la bague permettent de disposer la frette sur la bague en plusieurs positions axiales décalées distinctes. En d'autres termes, la frette 2 peut être engagée sur la bague avec son bord inférieur 23 qui s'étend plus ou moins vers le bas à partir de l'extrémité inférieure de la jupe 11. Ceci permet de disposer et de bloquer la frette sur la bague avec le bord inférieur 23 de la frette en contact de l'épaulement 35 du récipient 3. Et ceci, quelle que soit la hauteur du col 31. Les moyens de retenue axiale comprennent ainsi plusieurs éléments de prise mutuelle qui définissent des positions d'engagement axial distinctes de la frette sur la bague. Ces éléments de prise peuvent être formés soit par la frette, soit par la bague. Ces éléments de prise permettent de définir des positions axiales déterminées de blocage de la frette par rapport à la bague en fonction de la physionomie du col de récipient.According to the invention, the axial retention means of the hoop on the ring make it possible to arrange the hoop on the ring in several distinct offset axial positions. In other words, the
En se référant au premier mode de réalisation des
L'extrémité inférieure 13 peut venir en butée contre les créneaux du fait que la bague, réalisée en matière plastique, a toujours tendance à se déformer ou fluer vers l'extérieur.The
En se référant aux
On se réfèrera maintenant aux
Tout comme dans le premier mode de réalisation, l'épaulement 25 de la partie ourlée 24 peut venir en prise sous la collerette saillante 16 pour prépositionner la frette d'habillage 2 sur la bague de fixation.As in the first embodiment, the
Sur la
En variante, on peut également prévoir de former les moyens de retenue au niveau de la partie supérieure de la jupe et de la frette.Alternatively, it is also possible to form the retaining means at the upper part of the skirt and the hoop.
La bague est de préférence réalisée en matière plastique et la frette peut être réalisée en métal ou en matière plastique.The ring is preferably made of plastic and the hoop can be made of metal or plastic.
On peut également remarquer que la frette peut venir en prise avec la bague à un autre endroit que son extrémité inférieure libre.It may also be noted that the hoop may engage the ring at a location other than its free lower end.
Dans tous les modes de réalisation, la frette d'habillage 2 est accrochée et verrouillée dans des positions axiales qui peuvent varier par exemple en fonction de la physionomie du col de récipient.In all embodiments, the
