Description

Système de fixation et distributeur de produit fluide utilisant un tel système  Fixing system and fluid dispenser using such a system
La présente invention concerne un système de fixation pour fixer un organe de distribution, tel qu'une pompe ou une valve, sur un col de réservoir pour constituer un distributeur de produit fluide. L'organe de distribution est actionnable manuellement par l'utilisateur à l'aide d'un ou de plusieurs doigt(s), de manière à distribuer du produit fluide sous forme dosée ou non. De tels distributeurs de produit fluide sont fréquemment utilisés dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie.  The present invention relates to a fastening system for fixing a dispensing member, such as a pump or a valve, on a tank neck to form a fluid dispenser. The dispensing member is manually operable by the user with the aid of one or more finger (s), so as to dispense the fluid in metered form or not. Such fluid dispensers are frequently used in the fields of perfumery, cosmetics or even pharmacy.
Dans l'art antérieur, il existe déjà des systèmes de fixation comprenant une bague de fixation associée à une frette rigide engagée autour de la bague de fixation. La bague comprend en général une jupe destinée à être engagée autour du col, cette jupe comprenant des pattes de fixation destinées à venir en prise fixante avec un profil approprié formé par le col. On peut par exemple prévoir un filetage au niveau de la paroi externe du col, et les pattes de fixation vont ainsi venir en prise filetée avec le col. On peut également imaginer d'autres types de profil pour le col permettant par exemple un encliquetage ou un accrochage. Il est fréquent d'utiliser la frette rigide pour pousser les pattes de fixation contre le profil approprié du col.  In the prior art, there already exist fixing systems comprising an attachment ring associated with a rigid hoop engaged around the fixing ring. The ring generally comprises a skirt intended to be engaged around the neck, this skirt comprising fixing lugs intended to come into fixed engagement with a suitable profile formed by the collar. For example, it is possible to provide a thread at the level of the external wall of the neck, and the fastening tabs will thus come into threaded engagement with the neck. One can also imagine other types of profile for the neck allowing for example a snap or a snap. It is common to use the rigid hoop to push the brackets against the appropriate profile of the neck.
Dans le cadre de la présente invention, le distributeur de produit fluide est démontable : le système de fixation peut être retiré du col par une action appropriée, tel que la traction, le dévissage, la rotation ou une action combinée. Ainsi, l'utilisateur peut directement accéder au contenu du réservoir, par exemple pour recueillir le reste de produit fluide, notamment lorsqu'il s'agit d'une crème. La capacité de démontage du distributeur peut également être mise à profit dans un but de recyclage.  In the context of the present invention, the fluid dispenser is removable: the fastening system can be removed from the neck by a suitable action, such as traction, unscrewing, rotation or a combined action. Thus, the user can directly access the contents of the tank, for example to collect the remaining fluid, especially when it is a cream. The disassembly capacity of the dispenser can also be used for recycling purposes.
Cependant, cette capacité de démontage permet également à un utilisateur malveillant d'altérer ou de remplacer le produit fluide initialement contenu dans le réservoir, puis de remonter le système de fixation pour reconstituer le distributeur de produit fluide. De ce fait, le démontage du système de fixation engendre une insécurité quant à l'authenticité du contenu du distributeur. However, this disassembly ability also allows a malicious user to alter or replace the fluid product initially contained in the tank, then reassemble the fastening system to reconstitute the fluid dispenser. As a result, the dismantling of the fastening system creates insecurity as to the authenticity of the distributor's contents.
La présente invention a pour but de remédier à cet inconvénient de l'art antérieur lié aux distributeurs de produit fluide démontables.  The present invention aims to overcome this drawback of the prior art related to removable fluid dispensers.
Pour ce faire, la présente invention prévoit que la jupe comprenne en outre au moins une patte de butée destinée à venir en butée axiale sur le col, lorsque l'on tente de remonter la bague de fixation sur le col après un premier démontage du distributeur. En d'autres termes, la patte de butée va empêcher le remontage du distributeur en s'interposant entre les pattes de fixation et le col du réservoir. En butant sur le col, la patte de butée va empêcher l'engagement des pattes de fixation autour du col.  To do this, the present invention provides that the skirt further comprises at least one abutment lug intended to come into axial abutment on the neck, when attempting to raise the fixing ring on the neck after a first disassembly of the distributor. . In other words, the stop tab will prevent reassembly of the dispenser by interposing between the fastening lugs and the neck of the tank. By abutting on the neck, the stop tab will prevent the engagement of the fastening tabs around the neck.
Avantageusement, la patte de butée, après démontage, fait saillie radialement vers l'intérieur par rapport aux pattes de fixation, de manière à venir en butée sur le col de réservoir en cas de tentative de remontage.  Advantageously, the abutment lug, after disassembly, protrudes radially inwardly relative to the fastening lugs, so as to abut on the tank neck in case of attempted reassembly.
Bien entendu, il ne faut pas que la patte de butée empêche le montage initial du distributeur. Pour ce faire, la présente invention prévoit que la patte de butée fasse saillie radialement vers l'extérieur avant engagement de la frette autour de la jupe. Lors du montage, la patte de butée est déformée radialement vers l'intérieur par la frette, avantageusement par pivotement.  Of course, it is not necessary that the stopper tab prevents the initial assembly of the dispenser. To do this, the present invention provides that the abutment lug protrudes radially outward before engagement of the hoop around the skirt. During assembly, the abutment lug is deformed radially inwards by the hoop, preferably by pivoting.
Selon une forme de réalisation pratique, la patte de butée comprend une section supérieure ayant une extrémité supérieure reliée au restant de la bague et une extrémité inférieure, et une section inférieure ayant une extrémité supérieure reliée à l'extrémité inférieure de la section supérieure, les deux sections s'étendant l'une par rapport à l'autre en faisant un angle, la section supérieure s'évasant vers l'extérieur avant engagement de la frette autour de la jupe. Avantageusement, la patte de butée est définitivement déformée vers l'intérieur par la frette au niveau de l'extrémité supérieure de la section supérieure reliée au restant de la bague. De préférence, la section supérieure s'étend axialement et la section inférieure s'étend vers l'intérieur après engagement de la frette autour de la jupe. Ainsi, la patte de butée subit à la fois une déformation définitive par déformation ou pivotement au niveau où elle est raccordée au restant de la bague et une déformation souple élastique réversible sur sa longueur par appui sur le col du réservoir. De cette manière, la patte de butée va rester dans sa position pivotée vers l'intérieur après démontage, mais elle va se détendre élastiquement de manière à retrouver sa forme initiale dès qu'elle n'est plus sollicitée contre le col. Cette combinaison de déformation définitive et réversible permet à la patte de butée de ne pas gêner le montage du distributeur, d'autoriser son démontage et d'empêcher son remontage après démontage. La patte de butée est empêchée de retourner dans son orientation initiale par la frette rigide qui l'entoure. Cependant, elle va retrouver sa configuration initiale, dès retrait du col, avec une orientation modifiée. According to a practical embodiment, the stop lug comprises an upper section having an upper end connected to the remainder of the ring and a lower end, and a lower section having an upper end connected to the lower end of the upper section, the two sections extending relative to each other at an angle, the upper section flaring outward before engagement of the hoop around the skirt. Advantageously, the abutment lug is definitively deformed inwards by the hoop at the upper end of the upper section connected to the remainder of the ring. Preferably, the upper section extends axially and the lower section extends inward after engagement of the hoop around the skirt. Thus, the abutment lug undergoes both a definitive deformation by deformation or pivoting at the same time. where it is connected to the remainder of the ring and a resilient elastic deformation reversible along its length by pressing on the neck of the tank. In this way, the stop lug will remain in its inwardly rotated position after disassembly, but it will elastically relax so as to return to its original shape as soon as it is no longer pressed against the neck. This combination of final and reversible deformation allows the stop tab not to interfere with the dispenser assembly, to allow disassembly and prevent reassembly after disassembly. The stop tab is prevented from returning to its initial orientation by the rigid band around it. However, it will return to its original configuration, once removed from the cervix, with a modified orientation.
L'invention définit également un distributeur de produit fluide comprenant un réservoir de produit fluide comprenant un col, un organe de distribution, tel qu'une pompe et un système de fixation tel que défini ci- dessus, dans lequel la frette fait pivoter définitivement la patte de butée vers l'intérieur et la sollicite élastiquement contre le col du réservoir. Avantageusement, le col comprend un filetage externe, les pattes de fixation étant en prise avec le filetage externe du col, la frette poussant les pattes de fixation contre le col.  The invention also defines a fluid dispenser comprising a fluid reservoir comprising a neck, a dispenser member, such as a pump and a fastening system as defined above, in which the collar permanently rotates the dispenser. stop tab inward and resiliently bias against the neck of the tank. Advantageously, the neck comprises an external thread, the fixing lugs being engaged with the external thread of the neck, the collar pushing the fastening lugs against the neck.
L'esprit de la présente invention réside dans le fait d'utiliser une ou plusieurs patte(s) de butée qui n'empêche(nt) ni le montage ni le démontage, mais qui interdisent tout remontage du distributeur. Pour cela, l'orientation des pattes de butée doit être modifiée de manière à se trouver sur le chemin entre les pattes de fixation et le col lorsque l'on veut remonter le distributeur. La frette rigide est avantageusement utilisée pour modifier l'orientation des pattes de butée ainsi que pour les déformer élastiquement pour qu'elles puissent se détendre élastiquement dès retrait du col pour se trouver dans le passage entre les pattes de fixation et le col.  The spirit of the present invention lies in the fact of using one or more stop tab (s) which prevents (s) neither assembly nor disassembly, but which prohibit reassembly of the dispenser. For this, the orientation of the stop tabs must be modified so as to be on the path between the fastening lugs and the neck when you want to go up the dispenser. The rigid hoop is advantageously used to change the orientation of the stop tabs as well as to deform elastically so that they can elastically relax upon withdrawal of the neck to be in the passage between the fastening lugs and the neck.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d'exemple non limitatif, un mode de réalisation de l'invention.  The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting example, an embodiment of the invention.

La figure 7 est une vue en perspective découpée du système de fixation des figures précédentes lors d'une tentative de remontage.  Figure 7 is a cutaway perspective view of the fastening system of the preceding figures during an attempt to reassemble.
On se référera tout d'abord aux figures 1 à 3 pour décrire en détail un mode de réalisation non limitatif d'un système de fixation de l'invention. Ce système de fixation comprend une bague de fixation 1 associée à une frette rigide 2 qui est destinée à venir s'engager avec serrage radial autour de la bague de fixation 1 , comme on le verra ci-après. La bague de fixation 1 peut être réalisée par injection moulage de matière plastique appropriée. Quant à la frette rigide 2, elle peut également être réalisée en matière plastique, mais de préférence elle est réalisée en métal, de manière à conférer un attrait esthétique au distributeur. Le système de fixation ainsi constitué par la bague 1 et la frette 2 sert à la fixation d'un organe de distribution 3, tel qu'une pompe ou une valve, sur un col de réservoir 41 de manière à constituer un distributeur de produit fluide. Le système de fixation a une double fonction, à savoir une fonction de fixation, mais également une fonction d'étanchéité. Referring first to Figures 1 to 3 to describe in detail a non-limiting embodiment of a fastening system of the invention. This fixing system comprises a fixing ring 1 associated with a rigid hoop 2 which is intended to engage with radial clamping around the fixing ring 1, as will be seen below. The fixing ring 1 can be made by injection molding of suitable plastic material. As for the rigid hoop 2, it can also be made of plastic, but preferably it is made of metal, so as to confer an aesthetic appeal to the distributor. The fastening system thus constituted by the ring 1 and the hoop 2 serves to fix a dispensing member 3, such as a pump or a valve, on a tank neck 41 so as to constitute a fluid dispenser . The fastening system has a dual function, namely a fastening function, but also a sealing function.
Ainsi, le produit fluide stocké dans le réservoir ne peut être extrait qu'à travers l'organe de distribution. Thus, the fluid product stored in the reservoir can be extracted only through the dispensing member.
La bague de fixation 1 comprend des moyens de réception 1 1 pour la réception de l'organe de distribution 3. Les moyens de réception 1 1 peuvent par exemple se présenter sous la forme d'un logement annulaire d'encliquetage dans lequel est reçue une collerette saillante formée par l'organe de distribution. La bague 1 forme également une ouverture axiale 12 qui s'étend à l'intérieur des moyens de fixation 1 1 , et qui sert au passage de la tige d'actionnement de l'organe de distribution, qui est déplaçable axialement en va-et-vient. Extérieurement aux moyens de réception 1 1 , la bague forme un plateau annulaire 13 qui vient se positionner sur le bord annulaire du col du réservoir, avec une interposition éventuelle d'un joint de col annulaire. Enfin, la bague de fixation 1 1 forme extérieurement une jupe 14 qui est réalisée de manière discontinue dans sa partie inférieure, formant ainsi des pattes de fixation 15 et des pattes de butée 16 séparées par des fentes 17 et intercalées de manière alternée. Une patte de fixation 15 est adjacente à deux pattes de butée 16, et vice versa. Comme on peut le voir sur la figure 3, la bague de fixation 1 , dans ce mode de réalisation particulier, comprend trois pattes de fixation 15 et trois pattes de butée 16. L'organe de distribution 3 s'étend à l'intérieur de la jupe 14, comme on peut le voir sur les figures 2 et 3. L'organe de distribution 3 forme un corps 31 dont l'extrémité supérieure est engagée dans les moyens de réception 1 1 . A son extrémité inférieure, le corps 1 1 forme une entrée de produit fluide 32 pourvue d'un tube plongeur 33. The fixing ring 1 comprises receiving means 1 1 for receiving the dispensing member 3. The receiving means 1 1 can for example be in the form of an annular latching housing in which is received a protruding flange formed by the dispensing member. The ring 1 also forms an axial opening 12 which extends inside the fastening means 1 1, and which serves for the passage of the actuating rod of the dispensing member, which is movable axially back and forth. Externally to the receiving means January 1, the ring forms an annular plate 13 which is positioned on the annular edge of the neck of the tank, with possible interposition of an annular neck seal. Finally, the fixing ring 1 1 externally forms a skirt 14 which is made discontinuously in its lower part, thus forming fastening lugs 15 and abutment lugs 16 separated by slots 17 and interspersed alternately. A fixing lug 15 is adjacent to two stop lugs 16, and vice versa. As can be seen in FIG. 3, the fixing ring 1, in this particular embodiment, comprises three fastening lugs 15 and three abutment lugs 16. The dispensing member 3 extends inside the the skirt 14, as can be seen in Figures 2 and 3. The dispensing member 3 forms a body 31 whose upper end is engaged in the receiving means 1 January. At its lower end, the body 11 forms a fluid inlet 32 provided with a dip tube 33.
Les pattes de fixation 15 s'étendent librement vers le bas et forment intérieurement un ou plusieurs profil(s) 151 destiné(s) à venir en prise avec le col du réservoir, comme on le verra ci-après. Les profils 151 peuvent être préformés de manière à s'adapter de manière complémentaire au col du réservoir. En variante, les profils 151 sont destinés à être déformés contre le col du réservoir de manière à imprimer une empreinte négative dans ces profils. Ces profils 151 peuvent par exemple servir au vissage et/ou au dévissage sur un col fileté. Ils peuvent également servir à l'encliquetage ou à l'accrochage sur un col approprié. La technique de fixation des pattes 15 sur le col n'est pas critique pour la présente invention, dans la mesure où la bague de fixation peut être retirée du col du réservoir sans détruire le système de fixation. Les pattes de fixation 15 s'étendent avec un léger retrait par rapport à la partie supérieure continue de la jupe 14. Toutefois, lorsque l'on engage les pattes de fixation 15 sur un col de réservoir, celles-ci sont déformées vers l'extérieur en s'évasant, de manière à pouvoir être poussées vers l'intérieur contre le col par la frette rigide 2. The fixing lugs 15 extend freely downwards and form inwardly one or more profile (s) 151 intended (s) to come into engagement with the neck of the reservoir, as will be seen below. The profiles 151 may be preformed so as to fit in a complementary manner to the neck of the reservoir. Alternatively, the profiles 151 are intended to be deformed against the neck of the reservoir so as to print a negative impression in these profiles. These profiles 151 may for example be used for screwing and / or unscrewing on a threaded neck. They can also be used to snap or snap on a suitable collar. The fastening technique of the flaps on the neck is not critical to the present invention, since the fastener ring can be removed from the neck of the tank without destroying the fastening system. The fixing lugs 15 extend with a slight shrinkage with respect to the continuous upper part of the skirt 14. However, when the fastening lugs 15 are engaged on a tank neck, these are deformed outwards by flaring, so as to be pushed inward against the neck by the rigid band 2.
Les pattes de butée 16 s'étendent également librement vers le bas de manière sensiblement similaire aux pattes de fixation 15. La forme particulière des pattes de butée 16 est cependant bien différente de celle des pattes de fixation 15. En effet, les pattes de butée 16 s'étendent, avant engagement définitif de la frette 2 autour de la bague, radialement vers l'extérieur par rapport au restant de la jupe 14, et notamment par rapport aux pattes de fixation 15. Comme on peut le voir sur la figure 2, la frette rigide 2 est pré-engagée sur la bague de fixation 1 , avec les pattes 15 et 16 qui font encore saillie axialement vers le bas. On peut remarquer que les pattes de butée 16 présentent un diamètre externe qui est supérieur à celui de la frette 2. Plus précisément, les pattes de butée 16 comprennent une section supérieure 161 présentant une extrémité supérieure 162 raccordée au restant de la jupe 14, ainsi qu'une extrémité inférieure 163, qui se raccorde à une section inférieure 164 définissant une extrémité inférieure libre 166. L'extrémité supérieure 165 de la section inférieure 164 est raccordée à l'extrémité inférieure 163 de la section supérieure 161 , comme on peut le voir très clairement sur la figure 1 . On peut également remarquer que l'épaisseur de paroi de la section supérieure 161 au niveau de son extrémité supérieure The stop lugs 16 also extend freely downwards in a substantially similar manner to the fixing lugs 15. The particular form of the abutment lugs 16 is, however, very different from that of the attachment lugs 15. Indeed, the abutment lugs 16 extend, before definitive engagement of the hoop 2 around the ring, radially outwardly relative to the remainder of the skirt 14, and in particular with respect to the fixing lugs 15. As can be seen in FIG. 2 , the rigid hoop 2 is pre-engaged on the fixing ring 1, with the lugs 15 and 16 which are still projecting axially downwards. It may be noted that the stop lugs 16 have an outer diameter which is greater than that of the hoop 2. More specifically, the stop lugs 16 comprise an upper section 161 having an upper end 162 connected to the remainder of the skirt 14, and a lower end 163, which is connected to a lower section 164 defining a lower free end 166. The upper end 165 of the lower section 164 is connected to the lower end 163 of the upper section 161, as can be seen in FIG. see very clearly in Figure 1. It may also be noted that the wall thickness of the upper section 161 at its upper end
162 est réduite par rapport au restant de la patte de butée 16. Cette épaisseur de paroi réduite définit une zone de faiblesse permettant une déformation de la patte par pivotement au niveau de l'extrémité supérieure 162, sans déformer notablement le restant de la patte. Ainsi, on comprendra aisément que l'engagement de la frette 2 autour des pattes 15 et 16 va conduire au déplacement vers l'intérieur des pattes de butée 16 par pivotement autour de l'extrémité supérieure 162. On peut remarquer que la section supérieure 161 s'étend de manière inclinée vers l'extérieur et vers le bas, alors que la section inférieure 164 est sensiblement ou parfaitement cylindrique. Un angle est ainsi formé entre la section supérieure 161 et la section inférieure 164, comme on peut clairement le voir sur les figures 1 et 2. La pente inclinée formée par la surface externe de la section supérieure 161 va également servir de surface de came pour le bord inférieur de la frette 2 lors de son engagement autour de la jupe 14. Ainsi, les pattes de butée 16 vont être progressivement déformées vers l'intérieur à mesure que la frette 2 s'engage sur les sections supérieures 161 des trois pattes 16. 162 is reduced relative to the remainder of the abutment lug 16. This reduced wall thickness defines a zone of weakness allowing deformation of the lug by pivoting at the upper end 162, without substantially deforming the remainder of the lug. Thus, it will be readily understood that the engagement of the hoop 2 around the lugs 15 and 16 will lead to the inward displacement of the stop lugs 16 by pivoting around the upper end 162. It may be noted that the upper section 161 extends inclined outwardly and downwardly, while the lower section 164 is substantially or perfectly cylindrical. An angle is thus formed between the upper section 161 and the lower section 164, as can clearly be seen in FIGS. 1 and 2. The inclined slope formed by the outer surface of the upper section 161 will also serve as a cam surface for the lower edge of the hoop 2 when engaged around the skirt 14. Thus, the stop lugs 16 will be progressively deformed inwardly as the hoop 2 engages on the upper sections 161 of the three legs 16.
Comme on peut le voir sur la figure 2, la frette rigide 2 est essentiellement cylindrique circulaire au niveau de son corps principal 21 , mais comprend également un rabat rentrant supérieur 22.  As can be seen in FIG. 2, the rigid hoop 2 is essentially circular cylindrical at its main body 21, but also comprises an upper reentrant flap 22.
En se référant maintenant à la figure 4, on voit le système de fixation des figures 2 et 3 engagé sur un col 41 d'un réservoir 4. Ce col 41 est pourvu extérieurement d'un filetage 42 qui va coopérer avec les profils 151 des pattes de fixation 15. Sur la figure 4, le montage n'est pas encore définitif : seules les pattes 15 et 16 sont engagées autour du col fileté 41 , mais la frette rigide 2 n'est pas encore totalement engagée autour de la bague. En exerçant une force suffisante sur l'extrémité supérieure de la frette 2, celle-ci va se déplacer vers le bas en poussant les pattes de fixation 15 fortement contre le col fileté du réservoir et en déformant par pivotement les pattes de butée 16 vers l'intérieur. Les profils 151 vont se déformer plastiquement contre le filetage 42 du col, alors que les pattes de butée 16 vont simplement être poussées ou sollicitées élastiquement contre ce col.  Referring now to Figure 4, we see the fastening system of Figures 2 and 3 engaged on a neck 41 of a reservoir 4. This neck 41 is externally provided with a thread 42 which will cooperate with profiles 151 of fixing lugs 15. In FIG. 4, the assembly is not yet final: only the lugs 15 and 16 are engaged around the threaded neck 41, but the rigid hoop 2 is not yet fully engaged around the ring. By exerting sufficient force on the upper end of the hoop 2, the hoop 2 will move downwardly by pushing the fastening lugs 15 firmly against the threaded neck of the tank and by pivotally deforming the abutment lugs 16 towards the hinge. inside. The profiles 151 will deform plastically against the threading 42 of the neck, while the abutment lugs 16 will simply be pushed or elastically biased against this neck.
En se référant aux figures 5 et 6, on voit que la section supérieure 161 de la patte de butée 16 s'étend maintenant dans le prolongement de la jupe 14, alors que la section inférieure 164 est orientée vers l'intérieur et vers le bas. Ceci est encore plus visible sur la figure 6 qui montre la bague de fixation 1 après déformation par la frette rigide 2. L'extrémité inférieure libre 166 des pattes de butée 16 sont effectivement en contact du col 41 , avec une déformation élastique non définitive, la seule déformation définitive étant celle réalisée au niveau de l'extrémité supérieure 162. Le distributeur est alors dans son état monté définitif, prêt à être utilisé.  Referring to Figures 5 and 6, it can be seen that the upper section 161 of the stop lug 16 now extends in the extension of the skirt 14, while the lower section 164 is oriented inwardly and downwardly. . This is even more visible in FIG. 6, which shows the fixing ring 1 after deformation by the rigid hoop 2. The free lower end 166 of the abutment lugs 16 are effectively in contact with the neck 41, with a non-definitive elastic deformation, the only final deformation being that performed at the upper end 162. The dispenser is then in its final mounted state, ready to be used.
Cependant, dans le cadre de l'invention, le distributeur est démontable, de sorte que l'utilisateur peut retirer le système de fixation du col du réservoir. Cette opération de démontage peut être réalisée par dévissage, comme dans le cas présent, mais elle peut également être réalisée par toute autre action appropriée permettant un démontage sans destruction du système de fixation. However, in the context of the invention, the dispenser is removable, so that the user can remove the fastening system of the neck of the tank. This disassembly operation can be performed by unscrewing, as in the present case, but it can also be carried out by any other appropriate action allowing disassembly without destruction of the fastening system.
En retirant la bague de fixation du col du réservoir, les pattes de butée 16 conservent leur orientation imposée par la frette rigide 2, et leurs extrémités libres 166 se libèrent du col, et peuvent ainsi se détendre élastiquement pour s'étendre radialement encore davantage vers l'intérieur. La figure 7 représente le distributeur à l'état démonté. On peut remarquer que l'extrémité libre 166 de la patte de butée 16 vient en butée sur le bord annulaire 43 du col du réservoir. Ainsi, il n'est plus possible de remonter le système de fixation sur le col, du fait que les pattes de butée 16 empêchent l'engagement des pattes de fixation 15 autour du col. En raison de l'orientation inclinée vers l'intérieur et vers le bas de la section inférieure 164, même si l'on appuie fortement sur ce système de fixation, cela aura tendance à engager ou à déformer encore davantage les pattes de butée 16 vers l'intérieur, et même à pénétrer légèrement dans le col du réservoir.  By removing the retaining ring from the neck of the reservoir, the abutment lugs 16 retain their orientation imposed by the rigid hoop 2, and their free ends 166 are released from the neck, and can thus elastically relax to extend radially further towards inside. Figure 7 shows the distributor in the disassembled state. It may be noted that the free end 166 of the abutment lug 16 abuts on the annular edge 43 of the neck of the reservoir. Thus, it is no longer possible to raise the fastening system on the neck, because the abutment lugs 16 prevent the engagement of the fastening lugs 15 around the neck. Because of the inclined inward and downward orientation of the lower section 164, even if this fastening system is strongly supported, this will tend to further engage or deform the abutment lugs 16 to inside, and even to penetrate slightly into the neck of the tank.
Grâce à l'invention, les pattes de butée 16 empêchent le remontage du distributeur, sans empêcher ni le montage ni le démontage. Ceci est rendu possible par une déformation combinée des pattes de butée 16, à savoir une déformation définitive par pivotement autour de leurs extrémités supérieures par l'engagement de la frette 2, et une déformation élastique réversible par appui élastique de leurs extrémités libres 166 contre le col.  Thanks to the invention, the stop tabs 16 prevent the reassembly of the dispenser, without preventing either assembly or disassembly. This is made possible by a combined deformation of the abutment lugs 16, namely a final deformation by pivoting around their upper ends by the engagement of the hoop 2, and a reversible elastic deformation by elastic support of their free ends 166 against the collar.
