Description

Dispositif de distribution de produit fluide à actionnement latéral Fluid dispensing device with lateral actuation
La présente invention concerne un dispositif de distribution de produit fluide, et plus particulièrement un dispositif de distribution de produit fluide à actionnement latéral. Dans la plupart des dispositifs de distribution de produit fluide, que ce soit dans le domaine de la pharmacie, de la parfumerie, de la cosmétique, voire d'autres domaines voisins, le produit est généralement expulsé au moyen d'une force d'actionnement réalisée de manière axiale. Cette force est souvent exercée par l'utilisateur en appuyant avec son pouce sur le fond du dispositif et en maintenant la tête du dispositif qui incorpore l'orifice de distribution avec d'autres doigts de la même main. Ce type de dispositif de distribution procure un certain nombre d'inconvénients, notamment dans le cas d'applications nasales, puisqu'il crée souvent un déplacement axial de l'ensemble du dispositif au moment de l' actionnement, notamment dû à la résistance que fournit le dispositif pendant l' actionnement. L'utilisateur doit légèrement forcer sur le fond du dispositif pour réaliser cet actionnement, et au moment où celui-ci a lieu, une partie de la force est libérée de sorte que le bras ou la main de l'utilisateur peut être entraîné dans cette même direction axiale, ce qui peut entraîner un risque de blessure, notamment lorsque l'orifice de distribution est introduit à l'intérieur de la narine.The present invention relates to a fluid dispenser device, and more particularly to a fluid actuator device with lateral actuation. In most fluid dispensing devices, whether in the field of pharmacy, perfumery, cosmetics, or even other neighboring fields, the product is generally expelled by means of an actuating force performed axially. This force is often exerted by the user by pressing with his thumb on the bottom of the device and holding the head of the device which incorporates the dispensing orifice with other fingers of the same hand. This type of dispensing device provides a certain number of drawbacks, in particular in the case of nasal applications, since it often creates an axial displacement of the entire device at the time of actuation, in particular due to the resistance that supplies the device during actuation. The user must slightly force on the bottom of the device to achieve this actuation, and at the moment it takes place, part of the force is released so that the user's arm or hand can be drawn into it. same axial direction, which can lead to a risk of injury, especially when the dispensing orifice is introduced inside the nostril.
Pour remédier à ce problème, il a été proposé d'utiliser les dispositifs à actionnement latéral, dans lesquels l'utilisateur n'exerce plus lui-même une force axiale sur le dispositif, mais au contraire exerce une force latérale ou transversale à l'axe de distribution du produit, par exemple au moyen d'un bouton ou d'un levier latéral pivotant, cette force transversale étant transformée en une force axiale. Dans ce type connu de dispositif de distribution à actionnement latéral, l'utilisateur maintient le dispositif dans sa main en agrippant le corps du dispositif, ou plus généralement la partie qui incorpore l'orifice de distribution, un doigt, par exemple le pouce, étant utilisé pour appuyer sur l'élément d'actionnement latéral. Selon le dispositif de distribution utilisé, en particulier selon le type de pompe, ou plus généralement le type de moyen de distribution nécessaire pour réaliser l'expulsion du produit, l'actionnement nécessite une force axiale plus ou moins importante. Or, dans les dispositifs de distribution à actionnement latéral connus, le transfert de la force radiale exercée par l'utilisateur en une force axiale permettant l'actionnement n'est pas total, de sorte que l'utilisateur doit appuyer plus fort dans un dispositif à actionnement latéral qu'il ne serait obligé de le faire s'il exerçait une pression axiale.To remedy this problem, it has been proposed to use lateral actuation devices, in which the user no longer exerts himself an axial force on the device, but on the contrary exerts a lateral or transverse force on the product distribution axis, for example by means of a pivoting button or lateral lever, this transverse force being transformed into an axial force. In this known type of dispensing device with lateral actuation, the user holds the device in his hand by gripping the body of the device, or more generally the part which incorporates the dispensing orifice, a finger, for example the thumb, being used to press the side actuator. Depending on the distribution device used, in particular depending on the type of pump, or more generally the type of distribution means necessary to carry out the expulsion of the product, actuation requires a greater or lesser axial force. However, in known lateral actuation dispensing devices, the transfer of the radial force exerted by the user into an axial force allowing actuation is not total, so that the user must press harder in a device with lateral actuation that it would not be obliged to do so if it exerted an axial pressure.
L'utilisateur doit alors soit exercer une force importante, ce qui n'est pas toujours possible, notamment avec des enfants ou les personnes âgées, ou alors on doit prévoir des moyens d'actionnement de dimension suffisamment grande pour permettre un transfert plus aisé. Cette augmentation de la dimension du dispositif présente toutefois souvent un inconvénient que ce soit en terme de coût de fabrication ou de stockage, ou même d'un point de vue de l'ergonomie d'utilisation. La présente invention a pour but de fournir un dispositif de distribution de produit fluide à actionnement latéral qui ne reproduit pas les inconvénients susmentionnés.The user must then either exert a significant force, which is not always possible, in particular with children or the elderly, or else provision must be made for actuation means of sufficiently large size to allow easier transfer. However, this increase in the size of the device often has a drawback, whether in terms of manufacturing or storage cost, or even from the point of view of ergonomics of use. The object of the present invention is to provide a device for dispensing a fluid product with lateral actuation which does not reproduce the abovementioned drawbacks.
Plus particulièrement, la présente invention a pour but de fournir un dispositif de distribution de produit fluide à actionnement latéral qui permet dans tous les cas de réaliser un actionnement latéral au moyen d'une force radiale la plus faible possible.More particularly, the present invention aims to provide a fluid dispensing device with lateral actuation which in any case allows lateral actuation by means of the lowest possible radial force.
La présente invention a également pour but de fournir un tel dispositif de distribution de produit fluide à actionnement latéral qui soit simple et peu coûteux à fabriquer, assembler et utiliser. La présente invention a également pour but de fournir un tel dispositif de distribution de produit fluide à actionnement latéral qui soit compact ergonomique et fiable.The present invention also aims to provide such a device for dispensing a fluid product with lateral actuation which is simple and inexpensive to manufacture, assemble and use. The present invention also aims to provide such a fluid dispensing device with lateral actuation which is compact ergonomic and reliable.

Avantageusement, ledit bord périphérique des moyens d'actionnement est le bord périphérique inférieur.Advantageously, said peripheral edge of the actuating means is the lower peripheral edge.
De préférence, ledit dispositif comporte deux éléments d'actionnement latéral diamétralement opposés l'un à l'autre par rapport audit corps. D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante d'un mode de réalisation particulier de celle-ci, faite en référence aux dessins joints, donnés à titre d'exemple non limitatif, et sur lesquels,Preferably, said device comprises two lateral actuating elements diametrically opposite one another relative to said body. Other characteristics and advantages of the present invention will appear more clearly during the following detailed description of a particular embodiment thereof, made with reference to the accompanying drawings, given by way of non-limiting example, and in which,
- la figure 1 est une vue schématique en section transversale partiellement éclatée d'un dispositif de distribution de produit fluide selon la présente invention, en position de repos,FIG. 1 is a schematic view in partially exploded cross section of a fluid dispenser device according to the present invention, in the rest position,

La description détaillée ci-après sera donc faite en référence à ce mode de réalisation particulier de l'invention, mais il est clair que la présente invention ne se limite pas à ce type de dispositif, mais pourrait au contraire également s'appliquer à des dispositifs de type bidose, c'est à dire contenant deux doses, ou même plusieurs doses.The example shown in the figures is a device for dispensing a fluid product called single-dose or single-dose, that is to say that it contains only one dose of product in its reservoir. The detailed description below will therefore be made with reference to this particular embodiment of the invention, but it is clear that the present invention is not limited to this type of device, but could on the contrary also apply to bidose type devices, ie containing two doses, or even several doses.
En référence à la figure 1, le dispositif de distribution comporte un corps 10 dans lequel est disposé un réservoir de produit fluide 20 relié d'une part à des moyens de distribution 30 et d'autre part à un orifice de distribution 25.With reference to FIG. 1, the dispensing device comprises a body 10 in which is disposed a fluid reservoir 20 connected on the one hand to distribution means 30 and on the other hand to a distribution orifice 25.
Les moyens de distribution 30 représentés sur les figures 1 et 2 sont réalisés sous la forme d'une chasse d'air qui est adaptée à générer un écoulement d'air comprimé qui, lorsque le pointeau 31 relié à la chasse d'air 30 vient percer la membrane du réservoir 20, expulse la bille d'obturation 22 en entraînant avec lui le produit contenu à l'intérieur du réservoir 20 en direction de l'orifice de distribution 25. Dans ce cas, le produit fluide est généralement une poudre. Pour actionner ce dispositif, il est donc nécessaire de comprimer le piston 40 de la chasse d'air 30, le déplacement axial dudit piston 40 comprimant l'air à l'intérieur de la chambre de la chasse d'air, jusqu'à ce que le pointeau 31 vienne percer la membrane 21 du réservoir 20 libérant ainsi l'écoulement d'air en direction d'abord de la bille d'obturation 22 puis de l'orifice de distribution 25. Cette compression axiale du piston 40, qui forme le moyen d'actionnement de la chasse d'air 30, nécessite une force croissante au fur à mesure qu'on comprime l'air, en raison de la résistance de cet air, jusqu'à ce que cet air comprimé soit libéré lors de l'actionnement.The distribution means 30 shown in FIGS. 1 and 2 are produced in the form of an air flush which is adapted to generate a flow of compressed air which, when the needle 31 connected to the air flush 30 comes pierce the membrane of the reservoir 20, expels the sealing ball 22 by carrying with it the product contained inside the reservoir 20 in the direction of the dispensing orifice 25. In this case, the fluid product is generally a powder. To activate this device, it is therefore necessary to compress the piston 40 of the air flush 30, the axial movement of said piston 40 compressing the air inside the air flush chamber, until that the needle 31 comes to pierce the membrane 21 of the reservoir 20 thus releasing the air flow in direction first of the shut-off ball 22 then of the dispensing orifice 25. This axial compression of the piston 40, which forms the means for actuating the air flush 30, requires increasing force as that the air is compressed, due to the resistance of this air, until this compressed air is released during actuation.
Selon l'invention, le dispositif comporte au moins deux éléments d'actionnement latéral répartis autour dudit corps (10). De préférence, il y a deux éléments d'actionnement 50, 60 qui sont diamétralement opposés par rapport au corps 10. De préférence, ces éléments d'actionnement latéral 50, 60 sont formés sur ledit corps 10, notamment de manière monobloc. Ces éléments d'actionnement latéral 50,60 sont adaptés à coopérer avec un bord 41 dudit piston 40, de préférence au moyen d'une surface de came 55, qui est de préférence formée par un plan incliné. Avantageusement, ledit bord 41 est le bord périphérique externe inférieur. Comme représenté sur les dessins, chaque élément d'actionnement latéralAccording to the invention, the device comprises at least two lateral actuating elements distributed around said body (10). Preferably, there are two actuating elements 50, 60 which are diametrically opposite with respect to the body 10. Preferably, these lateral actuating elements 50, 60 are formed on said body 10, in particular in one piece. These lateral actuating elements 50, 60 are adapted to cooperate with an edge 41 of said piston 40, preferably by means of a cam surface 55, which is preferably formed by an inclined plane. Advantageously, said edge 41 is the lower external peripheral edge. As shown in the drawings, each side actuator
50, 60 est réalisé de manière similaire, et comporte avantageusement une bride radiale 51 qui est reliée d'une part au corps 10 et qui se prolonge d'autre part par une aile 52 s'étendant vers le bas sur les dessins, et qui comporte ladite surface de came respective 55, 65. Comme représenté sur les dessins, cette surface de came 55, 65 de chaque élément d'actionnement latéral 50, 60 coopère avantageusement avec le bord périphérique 41, qui dans ce cas est le bord externe inférieur, et du fait que la surface de came est réalisée sous la forme d'un plan incliné, le point de contact entre l'élément d'actionnement latéral respectif et le moyen d'actionnement formé par le piston 40 reste ledit bord externe 41 tout au long de la course d'actionnement.50, 60 is produced in a similar manner, and advantageously comprises a radial flange 51 which is connected on the one hand to the body 10 and which is extended on the other hand by a wing 52 extending downward in the drawings, and which comprises said respective cam surface 55, 65. As shown in the drawings, this cam surface 55, 65 of each lateral actuating element 50, 60 advantageously cooperates with the peripheral edge 41, which in this case is the lower external edge , and the fact that the cam surface is produced in the form of an inclined plane, the point of contact between the respective lateral actuating element and the actuating means formed by the piston 40 remains said external edge 41 while along the actuation stroke.
Le fait de prévoir au moins deux éléments d'actionnement identiques et actionnés simultanément permet de démultiplier le transfert de force transversale en force axiale sur le piston 40, de sorte que l'utilisateur n'a plus qu'à exercer une force relativement faible sur les éléments d'actionnement latéral pour réaliser l'actionnement du dispositif, même si ce dispositif présente une résistance importante. Un aspect particulièrement intéressant de la présente invention est que dans les dispositifs de distribution de produit fluide, notamment ceux comportant une ou deux doses, l'effort d'actionnement est de plus en plus important au cours de la course d'actionnement, pour devenir maximal juste avant la distribution. La présente invention permet de répondre à cette particularité par le fait que la pente de la surface de came 55 respectivement 65 de chaque élément d'actionnement latéral 50 respectivement 60, qui est formée par un plan incliné, varie lors de l'actionnement. Ainsi, dans la position représentée sur la figure 1, la pente est assez importante, ce qui implique un transfert de force relativement faible, alors que dans la position représentée sur la figure 2, la pente est nettement moindre, de sorte que le transfert de la force radiale exercée par l'utilisateur est nettement supérieur à ce moment là. Ainsi, le transfert de force devient maximal en fin de course d'actionnement, au moment où la résistance du dispositif de distribution est également maximale, de sorte que la présente invention permet en fait un actionnement du dispositif au moyen d'une force relativement constante exercée sur les deux éléments d'actionnement latéral 50, 60. La modification de la pente en cours d'actionnement implique un transfert croissant de la force d'actionnement de l'utilisateur, qui compense l'augmentation de la résistance de la chasse d'air dans l'exemple représenté sur les figures.The fact of providing at least two identical actuation elements and actuated simultaneously makes it possible to multiply the transfer of transverse force into axial force on the piston 40, so that the user only has to exert a relatively weak force on the lateral actuating elements for actuating the device, even if this device has a high resistance. A particularly interesting aspect of the present invention is that in the fluid dispenser devices, in particular those comprising one or two doses, the actuation force is more and more important during the actuation stroke, to become maximum just before distribution. The present invention makes it possible to respond to this particularity by the fact that the slope of the cam surface 55 respectively 65 of each lateral actuating element 50 respectively 60, which is formed by an inclined plane, varies during actuation. Thus, in the position shown in Figure 1, the slope is quite significant, which implies a relatively small force transfer, while in the position shown in Figure 2, the slope is significantly less, so that the transfer of the radial force exerted by the user is significantly greater at this time. Thus, the force transfer becomes maximum at the end of the actuating stroke, at the moment when the resistance of the dispensing device is also maximum, so that the present invention in fact allows actuation of the device by means of a relatively constant force. exerted on the two lateral actuating elements 50, 60. The modification of the slope during actuation implies an increasing transfer of the actuating force of the user, which compensates for the increase in the resistance of the hunting of d in the example shown in the figures.
Dans les modes de réalisation représentés sur les figures 3 et 4, les moyens de distribution 30 sont réalisés sous la forme d'un piston 30 se déplaçant de manière étanche dans le réservoir 20. Les moyens d'actionnement 40 peuvent alors être soit reliés audit piston 30, comme représenté sur la figure 3, soit reliés audit réservoir 20, comme représenté sur la figure 4, pour induire un déplacement axial relatif entre ces deux éléments. Dans ce cas, la situation est identique, à savoir que la résistance est maximale en fin de course d'actionnement, et la présente invention permet également d'y remédier tel que décrit ci-dessus. Le réservoir 20 peut comporter une seule dose de produit, auquel cas cette dose est distribuée en un seul actionnement. En variante, le réservoir peut comporter deux ou plusieurs doses de produit, auquel cas des moyens de fractionnements de doses sont avantageusement prévus pour limiter la course du piston dans le réservoir. Dans ce cas, les moyens d'actionnement peuvent comporter des moyens élastiques de retour en position de repos après chaque actionnement. Avantageusement, des moyens de butée 59, 69 sont prévus pour définir la fin de course d'actionnement des éléments d'actionnement. Ces moyens de butée peuvent être réalisés sous la forme d'encoches 59, 69 réalisées dans la surface de came 55, 65 d'au moins un des éléments d'actionnement latéral 50, 60, de préférence dans chacun d'eux. Comme représenté sur la figure 2, ces encoches 59, 69 coopèrent en fin de course d'actionnement avec le bord inférieur du corps 10. Dans l'exemple susmentionné, dans lequel un piston coulisse dans un réservoir comportant deux ou plusieurs doses, ces encoches 59, 69 peuvent également permettre de définir les moyens de fractionnement de doses, en définissant la fin de course d'actionnement du piston dans le réservoir, la dose suivant étant distribuée lors de l'actionnement suivant.In the embodiments shown in FIGS. 3 and 4, the distribution means 30 are produced in the form of a piston 30 moving in leaktight manner in the tank 20. The actuation means 40 can then be either connected to said piston 30, as shown in Figure 3, or connected to said reservoir 20, as shown in Figure 4, to induce a relative axial movement between these two elements. In this case, the situation is identical, namely that the resistance is maximum at the end of the actuating stroke, and the present invention also makes it possible to remedy it as described above. The reservoir 20 can comprise a single dose of product, in which case this dose is dispensed in a single actuation. Alternatively, the reservoir may comprise two or more doses of product, in which case dose splitting means are advantageously provided to limit the stroke of the piston in the reservoir. In this case, the actuation means may comprise elastic means for returning to the rest position after each actuation. Advantageously, stop means 59, 69 are provided for defining the end of the actuation stroke of the actuating elements. These abutment means can be produced in the form of notches 59, 69 produced in the cam surface 55, 65 of at least one of the lateral actuating elements 50, 60, preferably in each of them. As shown in FIG. 2, these notches 59, 69 cooperate at the end of the actuating stroke with the lower edge of the body 10. In the above-mentioned example, in which a piston slides in a reservoir comprising two or more doses, these notches 59, 69 can also make it possible to define the means for fractionating doses, by defining the end of the actuation stroke of the piston in the reservoir, the next dose being dispensed during the next actuation.
En plus d'une démultiplication de la force d'actionnement sur le dispositif de distribution de produit fluide, et donc une facilitation de l'actionnement de celui-ci, l'utilisation de deux ou plusieurs éléments d'actionnement latéral de la présente invention fournit une ergonomie améliorée, et en particulier assure une symétrie au moment de l'actionnement, c'est à dire que l'utilisateur exerce environ la même force radiale sur chacun des éléments d'actionnement latéral 50, 60. Il s'ensuit une forte stabilité du dispositif de distribution dans son ensemble à la fois dans la direction axiale, puisque l'utilisateur n'exerce plus de force axiale sur le dispositif, et dans la positon radiale, puisque l'utilisateur exerce la même force de chaque côté du dispositif. Ceci n'était pas le cas avec le dispositif à actionnement latéral connu, dans lequel le dispositif était tenu dans la main et la force exercée seulement au moyen d'un doigt sur un côté du dispositif. Selon l'importance de la force à exercer, ceci pouvait entraîner un déséquilibre au niveau de la force radiale, et donc un déplacement du dispositif dans son ensemble dans la direction de cette force radiale. La présente invention surmonte donc cet inconvénient, qui peut être important lorsque l'orifice de distribution 25 est introduit dans une narine, auquel cas la précision de la distribution et l'absence de risque de blessures est favorisé par la présente invention.In addition to a reduction in the actuating force on the fluid dispensing device, and therefore a facilitation of the actuation thereof, the use of two or more lateral actuating elements of the present invention provides improved ergonomics, and in particular ensures symmetry at the time of actuation, that is to say that the user exerts approximately the same radial force on each of the lateral actuation elements 50, 60. This results in a high stability of the dispensing device as a whole both in the axial direction, since the user no longer exerts an axial force on the device, and in the radial position, since the user exerts the same force on each side of the device. This was not the case with the known lateral actuation device, in which the device was held in the hand and the force exerted only by means of a finger on one side of the device. Depending on the magnitude of the force to be exerted, this could cause an imbalance in the radial force, and therefore a displacement of the device as a whole in the direction of this radial force. The present invention therefore overcomes this drawback, which can be significant when the dispensing orifice 25 is introduced into a nostril, in which case the precision of the distribution and the absence of risk of injury is favored by the present invention.
Bien que la présente invention ait été décrite en référence à un mode de réalisation particulier de celle-ci, il est clair qu'elle n'est pas limitée à celui-ci. Comme déjà mentionné, le dispositif n'est pas nécessairement un monodose, mais pourrait être un bidose ou même un dispositif comportant plus que deux doses, du moment que des moyens de fractionnement de doses sont prévus dans le dispositif. Avantageusement, comme expliqué ci-dessus, ces moyens de fractionnement de doses peuvent faire partie des éléments d'actionnement latéral. De même, les moyens de distribution ne sont pas limités à la chasse d'air représentée sur les dessins, mais d'autres moyens de distribution, en particulier un piston coulissant dans le réservoir sont envisageables. D'autre part, le dispositif peut comporter plus de deux éléments d'actionnement latéral, par exemple trois ou quatre, répartis à intervalles réguliers autour du corps du dispositif. De même, le bord périphérique avec lequel coopère chaque élément d'actionnement latéral n'est pas nécessairement le bord inférieur, et n'est pas non plus nécessairement formé par une arête vive, mais pourrait au contraire être un bord incliné correspondant à la surface de came des éléments d'actionnement. D'autres modifications sont également réalisables par l'homme du métier sans sortir du cadre de la présente invention tel que défini par les revendications annexées. Although the present invention has been described with reference to a particular embodiment thereof, it is clear that it is not limited thereto. As already mentioned, the device is not necessarily a single dose, but could be a bidose or even a device comprising more than two doses, as long as means for dividing doses are provided in the device. Advantageously, as explained above, these dose fractionation means can be part of the lateral actuation elements. Likewise, the distribution means are not limited to the air flush shown in the drawings, but other distribution means, in particular a piston sliding in the tank can be envisaged. On the other hand, the device may include more than two lateral actuating elements, for example three or four, distributed at regular intervals around the body of the device. Similarly, the peripheral edge with which each lateral actuating element cooperates is not necessarily the bottom edge, and is not necessarily necessarily formed by a sharp edge, but could on the contrary be an inclined edge corresponding to the surface of the actuating elements. Other modifications can also be carried out by a person skilled in the art without departing from the scope of the present invention as defined by the appended claims.
