Description

Distributeur de produit fluide Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant un réservoir de volume variable par déplacement d'une paroi mobile de manière à réduire le volume du réservoir et un orifice de distribution. La paroi mobile peut se déplacer soit au moyen d'une déformation soit au moyen d'un coulissement étanche. Dans le premier cas, c'est le réservoir ou au moins une partie du réservoir qui subit une déformation, d'où l'utilisation d'un matériau souple déformable et/ ou élastique, et dans le second cas, on parle plutôt de systèmes à piston-suiveur dans lesquels un piston se déplace à l'intérieur d'un fût cylindrique de manière à réduire progressivement le volume utile du réservoir. Dans les deux cas, le volume du réservoir diminue à mesure que du produit fluide en est extrait. Le produit fluide n'est ainsi jamais en contact de l'air à l'intérieur du réservoir ce qui améliore la conservation du produit, en particulier lorsqu'il est sensible à l'oxydation ou à la détérioration au contact de l'air. Dans les distributeurs à réservoir déformable, on peut par exemple citer ceux dont la déformation du réservoir s'effectue par écrasement manuel : on parle alors couramment de "squeezze bottle". C'est directement la main de l'utilisateur qui sert de moyen d'écrasement du réservoir. En revanche, dans les systèmes à piston-suiveur, le piston-suiveur remonte dans le récipient soit automatiquement sous l'effet de la dépression créée dans le récipient après chaque actionnement du distributeur, soit à l'aide d'un ressort qui sollicite le piston dans le sens d'une réduction du volume interne du récipient.The present invention relates to a fluid dispenser comprising a reservoir of variable volume by displacement of a movable wall so as to reduce the volume of the reservoir and a dispensing orifice. The movable wall can be moved either by means of a deformation or by means of a sealed slide. In the first case, it is the tank or at least part of the tank which undergoes a deformation, hence the use of a flexible deformable and / or elastic material, and in the second case, we speak rather of systems piston follower in which a piston moves inside a cylindrical barrel so as to gradually reduce the useful volume of the tank. In both cases, the volume of the reservoir decreases as fluid is extracted from it. The fluid product is thus never in contact with the air inside the tank, which improves the conservation of the product, in particular when it is sensitive to oxidation or deterioration in contact with air. In distributors with a deformable reservoir, one can for example cite those whose deformation of the reservoir is effected by manual crushing: this is then commonly referred to as a "squeezze bottle". It is directly the user's hand that serves as a means of crushing the tank. On the other hand, in piston follower systems, the piston follower rises in the container either automatically under the effect of the vacuum created in the container after each actuation of the distributor, or using a spring which biases the piston in the direction of reducing the internal volume of the container.
La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en proposant un distributeur doté de moyens d'actionnement qui agissent sur la paroi mobile du distributeur.The present invention aims to remedy the aforementioned drawbacks of the prior art by proposing a dispenser provided with actuating means which act on the movable wall of the dispenser.
Le document EP-0 869 080 décrit un distributeur comprenant une poche souple réalisée sous la forme d'un soufflet hélicoïdal. Les spires formées par la paroi externe du soufflet sont en prise filetée dans une jupe rotative formant un filet annulaire unique. Ainsi, en tournant la jupe, les spires héhcoïdales du soufflet sont progressivement accumulées à la manière d'un accordéon. Pour permettre un vidage presque total de la poche, le filet annulaire unique de la jupe se trouve en partie haute de la poche, de sorte que le filet annulaire est initialement en prise avec la spire la plus haute du soufflet et vient ensuite progressivement en prise avec les spires inférieures à mesure que l'on tourne la jupe librement sur elle-même. En somme, on se sert ici de la flexibilité du soufflet pour permettre son écrasement et on vient en outre se servir de la résistance des spires hélicoïdales pour faire progresser le soufflet de l'autre côté du filet unique. La poche doit donc simultanément être déformable et rigide, car sans déformation, le soufflet ne peut pas être écrasé, et sans rigidité, les spires héhcoïdales ne restent pas en prise avec le filet unique. De plus, du fait que le filet unique est situé en partie haute du soufflet, le fond du réservoir est libre et ne fait que suivre. Il faut donc que le fond soit rigide. En somme, le soufflet doit être à la fois rigide et souple. Cette double exigence est antagoniste et par conséquent très difficile à réaliser en pratique. La présente invention a pour but de remédier à cet inconvénient de l'art antérieur en définissant un distributeur plus simple.The document EP-0 869 080 describes a dispenser comprising a flexible bag produced in the form of a helical bellows. The turns formed by the external wall of the bellows are in threaded engagement in a rotary skirt forming a single annular thread. Thus, by turning the skirt, the hehcoid turns of the bellows are gradually accumulated in the manner of an accordion. For allow almost total emptying of the pocket, the single annular thread of the skirt is located in the upper part of the pocket, so that the annular thread is initially engaged with the uppermost turn of the bellows and then gradually engages with the lower turns as we rotate the skirt freely on itself. In short, we use here the flexibility of the bellows to allow it to be crushed and we also use the resistance of the helical coils to advance the bellows on the other side of the single thread. The pocket must therefore simultaneously be deformable and rigid, because without deformation, the bellows cannot be crushed, and without rigidity, the hehcoidal turns do not remain engaged with the single thread. In addition, because the single thread is located in the upper part of the bellows, the bottom of the tank is free and only follows. The bottom must therefore be rigid. In short, the bellows must be both rigid and flexible. This double requirement is antagonistic and therefore very difficult to achieve in practice. The object of the present invention is to remedy this drawback of the prior art by defining a simpler dispenser.
Pour ce faire, les moyens d'actionnement sont rotatifs et comprennent un filetage en prise avec le réservoir. Le filetage peut comprendre plusieurs filets distincts. Avantageusement, le réservoir comprend une ou plusieurs brides de déplacement solidaires de la paroi mobile et en prise dans le filetage. Ainsi, par rotation des moyens d'actionnement, la paroi mobile se déplace translativement dans le sens d'une réduction du volume utile du réservoir. Il faut remarquer que les moyens d'actionnement agissent directement sur le fond du réservoir qui constitue la paroi mobile, contrairement au document européen précité, dans lequel le fond du réservoir est tiré vers le haut.To do this, the actuating means are rotary and include a thread engaged with the reservoir. The thread may include several separate threads. Advantageously, the reservoir comprises one or more displacement flanges secured to the movable wall and engaged in the thread. Thus, by rotation of the actuating means, the movable wall moves translatively in the direction of a reduction in the useful volume of the tank. It should be noted that the actuating means act directly on the bottom of the tank which constitutes the movable wall, unlike the aforementioned European document, in which the bottom of the tank is pulled upwards.
Selon une forme de réalisation, le distributeur comprend un corps, les moyens d'actionnement rotatifs étant montés rotatifs dans ledit corps sans effectuer de déplacement translatif par rapport audit corps. Les moyens d'actionnement tournent ainsi librement dans le corps en faisant remonter la paroi mobile pour réduire le volume du réservoir. Avantageusement, le corps forme une partie du réservoir. Selon une caractéristique de l'invention, le réservoir comprend un soufflet en prise étanche avec le corps, ledit soufflet formant la paroi mobile. Avantageusement, le soufflet comprend un collier de fixation étanche en prise avec un manchon de raccordement formé par le corps. Ainsi, le soufflet est d'une part fixement relié au corps et est d'autre part en prise filetée avec les moyens d'actionnement. Selon une forme de réalisation pratique, la paroi mobile est reliée au colher de fixation par une paroi déformable. En outre, l'orifice de distribution peut être formé dans le corps.According to one embodiment, the dispenser comprises a body, the rotary actuating means being rotatably mounted in said body without effecting translational movement relative to said body. The actuating means thus rotate freely in the body by raising the movable wall to reduce the volume of the reservoir. Advantageously, the body forms part of the reservoir. According to a characteristic of the invention, the reservoir comprises a bellows in tight engagement with the body, said bellows forming the movable wall. Advantageously, the bellows comprises a tight fixing collar engaged with a connection sleeve formed by the body. Thus, the bellows is on the one hand fixedly connected to the body and on the other hand is in threaded engagement with the actuating means. According to a practical embodiment, the movable wall is connected to the fixing collar by a deformable wall. In addition, the dispensing orifice can be formed in the body.
Selon un autre aspect de l'invention, les moyens d'actionnement forment un fond pour le distributeur.According to another aspect of the invention, the actuation means form a bottom for the dispenser.
Selon une autre caractéristique, les moyens d'actionnement comprennent un organe de préhension périphérique apte à entraîner les moyens d'actionnement en rotation libre dans le corps. On peut ainsi maintenir le corps d'une main et faire tourner les moyens d'actionnement de l'autre main. L'invention sera maintenant plus amplement décrite en référence au dessin joint donnant à titre d'exemple non limitatif un mode de réalisation de l'invention.According to another characteristic, the actuation means comprise a peripheral gripping member capable of driving the actuation means in free rotation in the body. We can thus hold the body with one hand and rotate the actuating means with the other hand. The invention will now be described more fully with reference to the accompanying drawing, which gives an embodiment of the invention by way of non-limiting example.
Sur les figures :In the figures:
- la figure 1 est une vue schématique en perspective d'un distributeur selon l'invention,FIG. 1 is a schematic perspective view of a dispenser according to the invention,
- la figure 2 est une vue éclatée en perspective du distributeur de la figure 1, etFIG. 2 is an exploded perspective view of the dispenser of FIG. 1, and
- la figure 3 est une vue en coupe transversale à travers le distributeur des figures 1 et 2. Le distributeur de produit fluide de l'invention comprend essentiellement trois éléments constitutifs, à savoir un soufflet 1, des moyens d'actionnement 2 et un corps ou coque 3.- Figure 3 is a cross-sectional view through the dispenser of Figures 1 and 2. The fluid dispenser of the invention essentially comprises three constituent elements, namely a bellows 1, actuating means 2 and a body or shell 3.
Le soufflet 1 est une pièce monobloc par exemple réalisée dans un matériau souple déformable tel qu'un élastomère ou un thermoplastique élastomère. Il présente de bonnes propriétés de déformabihté dans des zones bien précises. Le soufflet 1 comprend une paroi de fond 11 sensiblement rigide. Cette paroi de fond 11 peut être parfaitement plane, mais elle peut également être convexe comme représenté sur la figure 3.The bellows 1 is a single piece, for example made of a flexible deformable material such as an elastomer or an elastomeric thermoplastic. It has good deformability properties in very specific areas. The bellows 1 comprises a substantially rigid bottom wall 11. This bottom wall 11 can be perfectly flat, but it can also be convex as shown in FIG. 3.
On peut en effet voir sur cette figure 3 que la paroi de fond 11 forme une sorte de dôme ou de godet renversé qui fait saillie vers le haut. Sur sa périphérie extérieure, la paroi de fond 11 définit au moins une bride de déplacement 13 sensiblement rigide. Sur les figures, il y a trois brides 13.It can indeed be seen in this figure 3 that the bottom wall 11 forms a kind of dome or overturned bucket which projects upwards. On its outer periphery, the bottom wall 11 defines at least one substantially rigid displacement flange 13. In the figures, there are three flanges 13.
Le soufflet 1 forme également un colher de fixation 15 qui est également sensiblement rigide. Ce collier de fixation 15 peut par exemple définir un logement d'encliquetage étanche 16 destiné à coopérer avec un organe complémentaire comme on le verra ci-après. Le soufflet 1 comprend également une paroi déformable 14 qui relie le collier de fixation 15 à la paroi de fond 11. La déformabihté de la paroi 14 peut par exemple être obtenue par une épaisseur de paroi inférieure par rapport à celle de la paroi de fond 11 ou du collier de fixation 15. Ainsi, il est possible de rapprocher translativement la paroi 11 du collier de fixation 15 par déformation de la paroi 14. Plus précisément, on peut voir sur les figures 2 et 3 que la paroi déformable 14 forme un pli adapté à s'accentuer si l'on exerce une pression tendant à rapprocher le collier 15 des brides 13. C'est précisément cette paroi déformable 14 qui donne le nom à la pièce puisqu'elle lui confère une fonction de soufflet. On peut bien entendu imaginer d'autres moyens pour réaliser une pièce déformable. Le soufflet 1 peut par exemple être remplacé par une poche souple fixée sur un support de poche remplissant la fonction du collier de fixation 15. La paroi de fond 11 peut être remplacée par une plaque sur laquelle vient reposer la poche souple. Les brides de déplacement 13, peuvent être formées par la périphérie de la plaque supportant la poche souple. On peut encore imaginer d'autres formes de réalisation comme par exemple avec un piston-suiveur déplaçable dans un cylindre de coulissement.The bellows 1 also forms a fixing collar 15 which is also substantially rigid. This fixing collar 15 can for example define a tight snap-in housing 16 intended to cooperate with a complementary member as will be seen below. The bellows 1 also comprises a deformable wall 14 which connects the fixing collar 15 to the bottom wall 11. The deformability of the wall 14 can for example be obtained by a thickness of the wall that is less than that of the bottom wall 11 or of the fixing collar 15. Thus, it is possible to translate the wall 11 of the fixing collar 15 by deformation of the wall 14. More specifically, it can be seen in FIGS. 2 and 3 that the deformable wall 14 forms a fold suitable for accentuating if there is a pressure tending to bring the collar 15 closer to the flanges 13. It is precisely this deformable wall 14 which gives the name to the part since it gives it a bellows function. One can of course imagine other means for producing a deformable part. The bellows 1 can for example be replaced by a flexible pocket fixed on a pocket support fulfilling the function of the fixing collar 15. The bottom wall 11 can be replaced by a plate on which the flexible pocket rests. The displacement flanges 13 can be formed by the periphery of the plate supporting the flexible bag. One can also imagine other embodiments such as for example with a follower piston displaceable in a sliding cylinder.
Dans le mode de réalisation des figures, les moyens d'actionnement 2 comprennent une douille filetée intérieurement 20 de manière à former un ou plusieurs filets ou filetages internes 21. Comme on peut le voir sur la figure 3, les brides de déplacement 13 du soufflet sont en prise filetée avec ces filetages internes 21. En dessous de la douille filetée 20, les moyens d'actionnement définissent un élément d'actionnement et de préhension 23 que l'utilisateur peut saisir pour entraîner les moyens d'actionnement en rotation. Optionnellement, les moyens d'actionnement 2 forment un fond 22 qui sert avantageusement de fond au distributeur. Sur la paroi externe de la douille filetée 20, il est formé un cordon continu ou plusieurs segments de cordon saillants 24 qui s'étendent sur une partie ou la totalité de la périphérie de la douille 20. On comprend aisément qu'une rotation des moyens d'actionnement 2, alors que le soufflet 1 est maintenu fixement, entraîne un déplacement des brides 13 à l'intérieur de la douille filetée 20.In the embodiment of the figures, the actuating means 2 comprise an internally threaded bush 20 so as to form one or more internal threads or threads 21. As can be seen in FIG. 3, the displacement flanges 13 of the bellows are in threaded engagement with these threads internal 21. Below the threaded sleeve 20, the actuating means define an actuating and gripping element 23 that the user can grasp to drive the actuating means in rotation. Optionally, the actuation means 2 form a bottom 22 which advantageously serves as the bottom for the dispenser. On the external wall of the threaded bush 20, a continuous bead or several protruding bead segments 24 are formed which extend over part or all of the periphery of the bush 20. It is easily understood that a rotation of the means actuation 2, while the bellows 1 is fixedly fixed, causes the flanges 13 to move inside the threaded bush 20.
Le corps 3 du distributeur forme une sorte de coque extérieure qui confère en grande partie l'aspect esthétique au distributeur. Le corps 3 comprend une jupe périphérique 33 à l'intérieur de laquelle est disposée la douille 20 des moyens d'actionnement 2. Dans le mode de réalisation des figures, la jupe 33 est formée intérieurement avec un logement annulaire 34 dans lequel sont reçus les segments de cordon saillants 24 formés à l'extérieur de la douille filetée 20. L'engagement des segments de cordon 24 dans le logement 34 assure le maintien rotatif de la douille 20 dans la jupe 33. Ainsi, les moyens d'actionnement 2 peuvent tourner librement dans la jupe 33 mais ne peuvent pas s'en dégager. La rotation est libre, puisque les segments de cordon 24 et le logement 34 sont parfaitement circulaires et non spirales.The body 3 of the dispenser forms a sort of outer shell which largely imparts the aesthetic appearance to the dispenser. The body 3 comprises a peripheral skirt 33 inside which is the sleeve 20 of the actuating means 2. In the embodiment of the figures, the skirt 33 is formed internally with an annular housing 34 in which are received the protruding cord segments 24 formed outside of the threaded sleeve 20. The engagement of the cord segments 24 in the housing 34 ensures the rotatable holding of the sleeve 20 in the skirt 33. Thus, the actuation means 2 can rotate freely in the skirt 33 but cannot disengage from it. The rotation is free, since the cord segments 24 and the housing 34 are perfectly circular and not spiral.
Au-dessus de la jupe 33, le corps 3 forme un plateau 31 dans lequel est formé un trou qui sert d'orifice de distribution 32 pour le distributeur. Un manchon de raccordement 35 s'étend sous le plateau 31 autour de l'orifice de distribution 32. Ce manchon de raccordement présente un profil de fixation en prise avec le colher de fixation étanche 15 du soufflet 1. Ainsi, le soufflet 1 est relié de manière fixe même en rotation avec le corps 3. De ce fait, le soufflet 1 et le corps 3 forment ensemble un réservoir 12 de volume variable étant donné que la paroi mobile 11 peut se déplacer en direction du plateau 31 par déformation de la paroi 14. Ceci est précisément le cas dans les figures lorsque l'on fait tourner les moyens d'actionnement 2 en maintenant le corps 3 statique. L'utilisateur peut par exemple se saisir du corps 3 à l'aide de la main gauche et faire tourner les moyens d'actionnement 2 de la main droite en les saisissant au niveau de son élément d'actionnement et de préhension 23. Ceci a pour effet de faire remonter les brides de déplacement 13 dans les filetages internes de la douille 20. La paroi mobile 11 remonte alors vers le plateau 31 en réduisant le volume utile du réservoir 12. Le produit fluide stocké à l'intérieur du réservoir 12 est alors refoulé à travers l'orifice de distribution 32 de manière à pouvoir être collecté par l'utilisatrice sur le plateau 31.Above the skirt 33, the body 3 forms a plate 31 in which a hole is formed which serves as a dispensing orifice 32 for the dispenser. A connection sleeve 35 extends under the plate 31 around the dispensing orifice 32. This connection sleeve has a fixing profile engaged with the waterproof fixing collar 15 of the bellows 1. Thus, the bellows 1 is connected fixedly even in rotation with the body 3. As a result, the bellows 1 and the body 3 together form a reservoir 12 of variable volume since the movable wall 11 can move in the direction of the plate 31 by deformation of the wall 14. This is precisely the case in the figures when the actuating means 2 are rotated while keeping the body 3 static. User can for example grasping the body 3 using the left hand and rotating the actuating means 2 with the right hand by grasping them at the level of its actuating and gripping element 23. This has the effect of making reassemble the displacement flanges 13 in the internal threads of the bushing 20. The movable wall 11 then rises towards the plate 31 by reducing the useful volume of the reservoir 12. The fluid stored inside the reservoir 12 is then forced back through the dispensing orifice 32 so that it can be collected by the user on the tray 31.
Le réservoir 12 est ici formé par l'assemblage du soufflet 1 et du corps 3. On peut cependant imaginer d'autres formes de réahsation dans lesquels le réservoir 12 est formé par une pièce unique, par exemple une poche souple dont l'ouverture définit l'orifice de distribution 32. Dans ce cas, le plateau 31 ne servirait que de surface d'appui et de surface de réception pour récupérer le produit fluide. Optionnellement, le corps 3 peut être formé avec un couvercle 36 qui est relié de manière monobloc par un pont de matière 37 au reste du corps 3. Ce pont de matière 37 réalise ainsi une articulation pivotante permettant de faire pivoter le couvercle 36 par rapport à la jupe 33 et au plateau 31. Le couvercle 36 définit sur sa face inférieure un pointeau d'obturation 38 adapté à venir se loger de manière étanche dans l'orifice de distribution 32 pour l'obturer hermétiquement. Ceci est le cas lorsque le couvercle 36 est rabattu sur le plateau 31.The reservoir 12 is here formed by the assembly of the bellows 1 and the body 3. However, one can imagine other forms of réahsation in which the reservoir 12 is formed by a single piece, for example a flexible pocket whose opening defines the dispensing orifice 32. In this case, the plate 31 would only serve as a bearing surface and a receiving surface for recovering the fluid product. Optionally, the body 3 can be formed with a cover 36 which is connected in one piece by a material bridge 37 to the rest of the body 3. This material bridge 37 thus produces a pivoting articulation making it possible to pivot the cover 36 relative to the skirt 33 and the plate 31. The cover 36 defines on its underside a shutter needle 38 adapted to be housed in a sealed manner in the dispensing orifice 32 to seal it hermetically. This is the case when the cover 36 is folded down on the plate 31.
Grâce au distributeur de l'invention, il est possible d'obtenir une dose de produit fluide dont le volume est directement proportionnel à la quantité de rotation des moyens d'actionnement. Thanks to the dispenser of the invention, it is possible to obtain a dose of fluid product whose volume is directly proportional to the amount of rotation of the actuating means.
