Description

La présente invention concerne un dispositif de distribution de liquide utilisable en position droite, et ne comportant pas de tube-plongeur.The present invention relates to a liquid distribution device usable in an upright position, and not comprising a dip tube.

Plus spécifiquement, l'invention concerne un dispositif de distribution, adapté à être tenu à la main, et qui comporte une pompe montée sur un réservoir de liquide, la pompe étant au-dessus de la surface libre du liquide dans le résevroir pendant l'utilisation du dispositif.More specifically, the invention relates to a dispensing device, adapted to be held in the hand, and which comprises a pump mounted on a liquid reservoir, the pump being above the free surface of the liquid in the container during the use of the device.

Dans l'art antérieur, de tels dispositifs comportaient toujours un tube-plongeur qui s'étendait depuis le distributeur jusqu'au fond du réservoir. Un tel tube plongeur présente plusieurs inconvénients. En premier lieu, il interdit certaines formes de flacons originales, notamment dans le domaine de la parfumerie. De plus, un tube-plongeur dans un récipient transparent présente un désavantage du point de vue esthétique, et la grande diversité des formes de récipient implique l'obligation de fabriquer des tubes adaptés pratiquement à chaque forme spécifique. En outre, la variation de longueur du tube liée au fond d'eau des verreries empêche une définition industrielle dudit tube plongeur.In the prior art, such devices always included a dip tube which extended from the distributor to the bottom of the tank. Such a dip tube has several drawbacks. First, it prohibits certain forms of original bottles, particularly in the field of perfumery. In addition, a dip tube in a transparent container has an aesthetic disadvantage, and the great diversity of container shapes implies the obligation to manufacture tubes adapted to practically each specific shape. In addition, the variation in length of the tube linked to the bottom of the glassware prevents an industrial definition of said dip tube.

Il existe dans l'art antérieur des dispositifs appelés "squeeze-bottle", où le liquide est expulsé à travers un conduit de sortie par déformation de la paroi souple du récipient. Un tel dispositif est décrit dans les documents FR-A-1 539 702, FR-A-1 525 560 et US-A-3 382 870. Ces documents divulguent en outre l'utilisation d'un organe de rétention pour définir une dose unique. Toutefois, aucun de ces dispositifs ne fonctionne avec une pompe à précompression délivrant de manière très exacte une ou plusieurs doses prédéterminées. De même, ces dispositifs ne sont pas adaptables à des récipients à paroi rigide, tel que des flacons de parfumerie en verre par exemple.There exist in the prior art devices called "squeeze-bottles", where the liquid is expelled through an outlet conduit by deformation of the flexible wall of the container. Such a device is described in documents FR-A-1,539,702, FR-A-1,525,560 and US-A-3,382,870. These documents also disclose the use of a retention organ to define a dose. unique. However, none of these devices works with a precompression pump delivering very precisely one or more predetermined doses. Likewise, these devices are not adaptable to containers with rigid walls, such as glass perfume bottles for example.

La présente invention a donc pour objet un dispositif de distribution de liquide, comportant un distributeur monté sur un récipient contenant ledit liquide,
   dans lequel le liquide forme une surface libre dans le réservoir et le distributeur comporte un orifice d'entrée qui est disposé au-dessus de ladite surface libre pendant le fonctionnement normal du distributeur,
   caractérisé en ce que le distributeur est une pompe comportant un corps de pompe et en ce que le dispositif comporte un organe de rétention de liquide, qui communique avec l'orifice d'entrée de la pompe et avec le récipient, ledit organe de rétention de liquide étant adapté à recevoir un certain volume de liquide, lorsque le dispositif est agité ou incliné par rapport à une position droite, avec la pompe au-dessus du récipient, et adapté à retenir ledit volume de liquide en communication avec ledit orifice d'entrée de la pompe lorsque le dispositif est dans ladite position droite.The present invention therefore relates to a liquid distribution device, comprising a distributor mounted on a container containing said liquid,
in which the liquid forms a free surface in the reservoir and the dispenser has an inlet orifice which is disposed above said free surface during normal operation of the dispenser,
characterized in that the distributor is a pump comprising a pump body and in that the device comprises a liquid retention member, which communicates with the inlet port of the pump and with the container, said retention member liquid being adapted to receive a certain volume of liquid, when the device is agitated or inclined relative to an upright position, with the pump above the container, and adapted to retain said volume of liquid in communication with said inlet orifice of the pump when the device is in said straight position.

Ainsi, le volume de liquide retenu par l'organe de rétention constitue une réserve intermédiaire de liquide qui permet un ou plusieurs actionnements du dispositif.Thus, the volume of liquid retained by the retention member constitutes an intermediate reserve of liquid which allows one or more actuations of the device.

Selon une forme de réalisation, ledit organe de rétention a la forme d'une coupelle qui est disposée autour et en dessous de l'orifice d'entrée de la pompe lorsque le dispositif est dans sa position droite.According to one embodiment, said retention member has the form of a cup which is arranged around and below the inlet opening of the pump when the device is in its upright position.

Selon une autre forme de réalisation, ledit organe de rétention est fixé au corps de pompe, avantageusement par emboîtement.According to another embodiment, said retention member is fixed to the pump body, advantageously by interlocking.

Avantageusment, ledit organe de rétention comporte un fond et une paroi latérale cylindrique de diamètre extérieur légèrement inférieur au diamètre intérieur du col du récipient, l'organe de rétention comportant en outre autour de l'extrémité supérieur de sa paroi latérale, plusieurs pattes souples s'évasant vers le col du récipient selon une direction faisant un angle avec la verticale, les extrémités supérieures desdites pattes souples formant un cercle fictif dont le diamètre est supérieur audit diamètre intérieur du col du récipient, lesdites pattes souples pouvant se rabattre lors de la mise en place dudit organe de rétention à travers le col du récipient, puis reprendre leur forme évasée pour éventuellement venir buter, avec leurs extrémités supérieures, sur la paroi du récipient situé sous ledit col, lorsque la pompe est montée sur le récipient.Advantageously, said retention member has a bottom and a cylindrical side wall with an outside diameter slightly smaller than the inside diameter of the neck of the container, the retention member further comprising around the upper end of its side wall, several flexible tabs s flaring towards the neck of the container in a direction making an angle with the vertical, the upper ends of said flexible tabs forming a fictitious circle whose diameter is greater than said inside diameter of the neck of the container, said flexible tabs being able to fold back when put in place of said retention member through the neck of the container, then resume their flared shape to possibly abut, with their upper ends, on the wall of the container located under said neck, when the pump is mounted on the container.

Dans un autre mode de réalisation, ledit organe de rétention est fixé au col du récipient et comporte un fond et une paroi latérale cylindrique à l'extrémité supérieure de laquelle une surface annulaire s'étend de manière sensiblement horizontale vers l'extérieur dudit organe de rétention, ladite surface annulaire reposant sur l'extrémité supérieure du col du récipient, la paroi latérale cylindrique de l'organe de rétention comportant au moins une ouverture permettant le passage du liquide du réservoir dans l'organe de rétention.In another embodiment, said retaining member is fixed to the neck of the container and has a bottom and a cylindrical side wall at the upper end of which an annular surface extends substantially horizontally towards the outside of said retaining member. retention, said annular surface resting on the upper end of the container neck, the cylindrical side wall of the retention member comprising at least one opening allowing the passage of the liquid from the reservoir into the retention member.

En variante, ledit organe de rétention comporte autour de l'extrémité extérieure de ladite surface annulaire horizontale une bride sensiblement cylindrique s'étendant de part et d'autre de ladite surface annulaire, ladite bride cylindrique comportant dans sa partie inférieure des moyens de fixation sur le col du récipient.As a variant, said retention member comprises around the outer end of said horizontal annular surface a substantially cylindrical flange extending on either side of said annular surface, said cylindrical flange comprising in its lower part means for fixing to the neck of the container.

Selon une forme de réalisation, lesdits moyens de fixation comportent des pattes d'encliquetage venant s'encliqueter sur le col du récipient, ladite bride cylindrique étant alors du type bague à encliquetage. Selon un autre forme de réalisation, lesdits moyens de fixation comportent un filetage interne coopérant avec un filetage externe du col du récipient, ladite bride cylindrique étant donc du type bague vissable.According to one embodiment, said fixing means comprise latching tabs which snap onto the neck of the container, said cylindrical flange then being of the snap ring type. According to another embodiment, said fixing means comprise an internal thread cooperating with an external thread of the neck of the container, said cylindrical flange therefore being of the screwable ring type.

Avantageusement, ledit organe de rétention est réalisé en un matériau suffisamment souple pour faire office de joint d'étanchéité dans le col du récipient.Advantageously, said retention member is made of a material which is flexible enough to act as a seal in the neck of the container.

De préférence, le corps de pompe présente sur sa partie située dans le réservoir, des nervures ou des rainures pour retenir par capillarité une certaine quantité de liquide lors de l'inclinaison ou l'agitation du dispositif, cette quantité de liquide s'écoulant ensuite le long du corps de pompe dans l'organe de réception sous l'effet de la gravitation lorsque le dispositif est remis dans sa position droite.Preferably, the pump body has on its part located in the tank, ribs or grooves to retain by capillarity a certain amount of liquid during the tilting or the agitation of the device, this amount of liquid then flowing the along the pump body in the receiving member under the effect of gravitation when the device is returned to its upright position.

Selon un autre mode de réalisation de l'invention, ledit organe de rétention comporte une cavité adaptée à retenir ledit liquide par capillarité. Ladite cavité est disposée sous l'orifice d'entrée de la pompe, et ladite cavité est ouverte vers le bas lorsque le dispositif est en position droite. Ladite cavité peut comporter des nervures intérieures pour augmenter la surface de contact entre la paroi de ladite cavité et le volume de liquide retenu dans la cavité.According to another embodiment of the invention, said retention member comprises a cavity adapted to retain said liquid by capillary action. Said cavity is arranged under the inlet port of the pump, and said cavity is open downwards when the device is in the upright position. Said cavity may have internal ribs to increase the contact surface between the wall of said cavity and the volume of liquid retained in the cavity.

Pour recharger l'organe de rétention de liquide, il est nécessaire de retourner le dispositif en position inversée ou de l'agiter. Il est possible qu'un utilisateur ne pense pas systématiquement à retourner ou à agiter le dispositif avant de l'actionner, auquel cas l'actionnement ne produit aucune sortie de liquide ou désamorce le distributeur. Pour éviter cet inconvénient, le dispositif peut avoir une forme extérieure tel qu'il ne puisse être posé de façon stable qu'en position inversée ou inclinée.To recharge the liquid retention member, it is necessary to return the device to the inverted position or to shake it. It is possible that a user does not systematically think of turning over or shaking the device before actuating it, in which case the actuation produces no outflow of liquid or defuses the dispenser. To avoid this drawback, the device can have an external shape such that it can only be stably installed in an inverted or inclined position.

Une première application de l'invention concerne les pompes montées sur les réservoirs en matériau transparent et, par exemple des flacons de parfums en verre ou en cristal. Dans cette application, le dispositif peut être particulièrement avantageux, parce qu'il supprime le tube-plongeur habituel, particulièrement inesthétique dans un flacon transparent.A first application of the invention relates to the pumps mounted on the tanks of transparent material and, for example bottles of perfumes in glass or crystal. In this application, the device can be particularly advantageous, because it eliminates the usual dip tube, particularly unsightly in a transparent bottle.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la descripiton détaillée suivante de plusieurs formes de réalisation de l'invention, données à titre d'exemples non limitatifs, en regard des dessins joints.Other characteristics and advantages of the invention will appear during the following detailed description of several embodiments of the invention, given by way of nonlimiting examples, with reference to the accompanying drawings.

  • Figures 6 and 7 are schematic views of two possible external forms of the device according to the invention.

Le dispositif de la figure 1 comporte une pompe 1 montée sur un récipient 2. Le récipient 2 est rempli d'un liquide 3 qui présente une surface libre 4. Le volume situé au-dessus de la surface libre 4 peut être vide ou être rempli d'air ou d'un autre gaz, à pression atmosphérique ou à une autre pression (par exemple en surpression).The device of FIG. 1 comprises a pump 1 mounted on a container 2. The container 2 is filled with a liquid 3 which has a free surface 4. The volume situated above the free surface 4 can be empty or be filled of air or another gas, at atmospheric pressure or at another pressure (for example in overpressure).

La pompe 1 comporte un corps de pompe 7 ayant une extrémité d'entrée 7a, dotée d'un orifice d'entrée 5 qui communique avec le récipient 2. La pompe 1 comporte en outre une tige d'actionnement 8 creuse, montée coulissante dans le corps de pompe 7, et qui commande un piston (non représenté). La pompe 1 peut en outre comporter un poussoir 10 (figure 6) qui est monté sur la tige d'actionnement 8. Le poussoir comporte un orifice de sortie, qui communique avec la tige d'actionnement 8, pour permettre l'expulsion d'une dose de liquide.The pump 1 comprises a pump body 7 having an inlet end 7a, provided with an inlet orifice 5 which communicates with the container 2. The pump 1 also comprises a hollow actuating rod 8, slidably mounted in the pump body 7, and which controls a piston (not shown). The pump 1 may also comprise a pusher 10 (FIG. 6) which is mounted on the actuating rod 8. The pusher has an outlet orifice, which communicates with the actuating rod 8, to allow the expulsion of a dose of liquid.

Au voisinage de l'orifice d'entrée 5 de la pompe 1 est disposé un organe de rétention 6, qui est ici une coupelle, disposée autour de et sous l'orifice 5 dans la position représentée sur la figure 1, et qui est ouverte vers le haut. Cette coupelle peut être par exemple en matière plastique ou en verre. Avantageusement, la coupelle 6 comporte des nervures 12, par exemple quatre, qui permettent de fixer la coupelle 6 sur le corps de pompe 7, par exemple par emboîtement sur l'extrémité d'entrée 7a (appelé généralement porte tube) du corps de pompe.In the vicinity of the inlet orifice 5 of the pump 1 is arranged a retention member 6, which is here a cup, arranged around and under the orifice 5 in the position shown in FIG. 1, and which is open to the top. This cup can for example be made of plastic or glass. Advantageously, the cup 6 has ribs 12, for example four, which make it possible to fix the cup 6 on the pump body 7, for example by fitting on the inlet end 7a (generally called tube holder) of the pump body .

Sur les figures 2 et 3, est représentée une variante de la coupelle de la figure 1. Selon ce mode de réalisation, la coupelle 6 comporte un fond 16 et une paroi latérale 17 sensiblement cylindrique dont le diamètre extérieur est de préférence légèrement inférieur au diamètre intérieur du col 2a du récipient 2.In FIGS. 2 and 3, a variant of the cup in FIG. 1 is shown. According to this embodiment, the cup 6 has a bottom 16 and a substantially cylindrical side wall 17 whose outside diameter is preferably slightly less than the diameter inside of neck 2a of container 2.

Avantageusement, des pattes souples 18 peuvent être disposées autour de l'extrémité supérieure de ladite paroi latérale 17 de telle manière à s'évaser de ladite coupelle en direction du col 2 du réservoir en faisant un angle avec ladite paroi. Ainsi, les extrémités supérieures desdites pattes souples 18 forment un cercle fictif de diamètre supérieur au diamètre intérieur du col de récipient. Lors de la mise en place du corps de pompe 7 et de la coupelle 6 à travers le col 2a du récipient, les pattes souples 18 se rabattent pour coulisser le long dudit col puis s'écartent pour éventuellement venir buter avec leurs extrémités supérieures sur la paroi du récipient situé sous ledit col 2a. Outre le fait d'augmenter l'effet de capillarité au-dessus de la coupelle 6 et ainsi assurer un remplissage total de cette coupelle lors de l'actionnement du dispositif, les pattes souples 18 garantissent l'inviolabilité du dispositif. En effet, toute tentative de retirer la pompe 1 du récipient, pour par exemple le remplir afin de le réutiliser à l'insu du fabricant, entraînerait la chute de la coupelle 6 au fond du récipient 2, la coupelle ne pouvant plus passer à travers le col 2a du récipient 2 en raison de la présence des pattes souples 18.Advantageously, flexible tabs 18 can be arranged around the upper end of said side wall 17 so as to flare from said cup towards the neck 2 of the reservoir at an angle with said wall. Thus, the upper ends of said flexible tabs 18 form a fictitious circle with a diameter greater than the inside diameter of the container neck. When the pump body 7 and the cup 6 are put in place through the neck 2a of the container, the flexible tabs 18 fold down to slide along the said neck and then move apart to eventually abut with their upper ends on the wall of the container located under said neck 2a. In addition to increasing the capillary effect above the cup 6 and thus ensuring total filling of this cup when the device is actuated, the flexible tabs 18 guarantee the inviolability of the device. Indeed, any attempt to remove the pump 1 from the container, for example to fill it in order to reuse it without the knowledge of the manufacturer, would cause the cup 6 to fall to the bottom of the container 2, the cup no longer being able to pass through the neck 2a of the container 2 due to the presence of the flexible tabs 18.

Les figures 4 et 5 représentent un autre mode de réalisation de l'invention. La coupelle 6 est ici fixé sur le col 2a du récipient. Elle comporte un fond 16 et une paroi latérale cylindrique 17 s'étendant sur toute la hauteur du col 2a du récipient et comportant au moins une ouverture 19 pour laisser passer le produit du récipient 2 dans la coupelle 6. A l'extrémité supérieure de ladite paroi latérale 17, une surface annulaire 20 s'étend vers l'extérieur de la coupelle 6 de manière sensiblement horizontale. Cette surface annulaire 20 vient reposer sur l'extrémité supérieure du col 2a du récipient lorsque le dispositif est mis en place dans ledit récipient. La coupelle 6 et le corps de pompe 7, dont une partie 30 s'étend également au-dessus de ladite extrémité supérieure du col 2a du récipient, sont alors fixés au col du récipient par un moyen classique de fixation 40 tel que, par exemple une bague à encliquetage, comme représenté sur lafigure 4.Figures 4 and 5 show another embodiment of the invention. The cup 6 is here fixed on the neck 2a of the container. It comprises a bottom 16 and a cylindrical side wall 17 extending over the entire height of the neck 2a of the container and comprising at least one opening 19 for letting the product from the container 2 pass into the cup 6. At the upper end of said side wall 17, an annular surface 20 extends towards the outside of the cup 6 in a substantially horizontal manner. This annular surface 20 comes to rest on the upper end of the neck 2a of the container when the device is placed in said container. The cup 6 and the pump body 7, a part of which also extends above said upper end of the neck 2a of the container, are then fixed to the neck of the container by a conventional fixing means 40 such as, for example a snap ring, as shown in Figure 4.

Dans une variante de ce dispositif, représenté sur la figure 5, l'ensemble coupelle/moyen de fixation est réalisé en une pièce, la coupelle 6 comportant autour de l'extrémité extérieure de ladite surface annulaire horizontale 20, une bride 21 sensiblement cylindrique s'étendant verticalement de part et d'autre de ladite surface annulaire 20. Cette bride cylindrique 21 comporte dans sa partie inférieure 22 des moyens de fixation du dispositif sur le col du récipient. Ces moyens de fixation peuvent comporter des pattes d'encliquetage 23 venant s'encliqueter sur le col du récipient, comme représenté sur la figure 5. Dans ce cas, la bride cylindrique 21 s'apparente à une bague dite à encliquetage, bien connue dans l'état de la technique. Alternativement, lesdits moyens de fixation peuvent également comporter un filetage interne coopérant avec un filetage externe du col du récipient, ladite bride cylindrique 21 étant dans ce cas du type bague vissable.In a variant of this device, shown in FIG. 5, the cup / fixing means assembly is made in one piece, the cup 6 comprising around the outer end of said horizontal annular surface 20, a substantially cylindrical flange 21 s extending vertically on either side of said annular surface 20. This cylindrical flange 21 has in its lower part 22 means for fixing the device on the neck of the container. These fixing means may include latching tabs 23 which snap onto the neck of the container, as shown in FIG. 5. In this case, the cylindrical flange 21 is similar to a so-called snap ring, well known in the art. the state of the art. Alternatively, said fixing means may also include an internal thread cooperating with an external thread of the neck of the container, said cylindrical flange 21 being in this case of the screwable ring type.

Avantageusement, l'organe de rétention, c'est-à-dire la coupelle 6 dans les modes de réalisation décrits précédemment, est réalisé en un matériau suffisamment souple pour assurer l'étanchéité dans le col du récipient. Un tel matériau peut être par exemple un élastomère ou une matière thermoplastique-élastomère (TPE), et l'étanchéité peut être assurée soit verticalement sur l'intérieur du col de verre par l'intermédiaire de la paroi latérale 17, soit horizontalement sur l'extrémité supérieure du col du récipient, par l'intermédiaire de la surface annulaire horizontale 20.Advantageously, the retention member, that is to say the cup 6 in the embodiments described above, is made of a sufficiently flexible material to seal in the neck of the container. Such a material may for example be an elastomer or a thermoplastic-elastomer (TPE), and the seal may be provided either vertically on the inside of the glass neck by means of the side wall 17, or horizontally on the the upper end of the container neck, via the horizontal annular surface 20.

Bien que représenté sur les figures 2, 4 et 5 avec un fond plat, la coupelle 6 pourrait aussi être de forme tronconique avec un fond 16 réduit au minimum, ou de forme semi-sphérique, comme celle représentée sur la figure 1.Although shown in FIGS. 2, 4 and 5 with a flat bottom, the cup 6 could also be of frustoconical shape with a bottom 16 reduced to a minimum, or of semi-spherical shape, like that shown in FIG. 1.

Le dispositif fonctionne de la manière suivante.The device operates as follows.

Avant d'actionner le dispositif, on l'agite, on l'incline ou on le retourne en position inversée, avec la pompe 1 disposée sous le récipient 2. Le liquide 3 se trouve alors au voisinage de l'orifice d'entrée 5 de la pompe. On replace ensuite le dispositif en position droite, avec la pompe 1 disposée au-dessus du récipient 2. Au cours de ce mouvement de retournement, un certain volume 15 de liquide reste à l'intérieur de la coupelle 6. La rétention de liquide à l'intérieur de la coupelle 6 est due partiellement au fait que le mouvement de retournement est assez rapide. Mais cette rétention de liquide est aussi due à la capillarité, du fait de la surface de contact du liquide à l'intérieur 6a de la coupelle 6. Avantageusement, l'intérieur 6a de la coupelle 6 peut être doté de nervures pour augmenter la surface de contact entre le liquide et l'intérieur 6a de la coupelle, de façon à augmenter la rétention de liquide. De même comme représenté sur la figure 4, le corps de pompe 7 peut être muni sur sa partie située à l'intérieur du récipient 2 de rainures ou de nervures 50 permettant de retenir une certaine quantité de liquide lors de l'inclinaison ou l'agitation du dispositif, cette quantité de liquide s'écoulant ensuite le long du corps de pompe 7 dans l'organe de réception 6 sous l'effet de la gravité lorsque le dispositif est remis dans sa position droite. Cette mise en oeuvre assure un transfert d'un maximum de produit dans la coupelle, notamment lorsqu'il ne reste que peu de produit dans le récipient.Before activating the device, it is agitated, tilted or returned to the inverted position, with the pump 1 placed under the container 2. The liquid 3 is then at the near the inlet port 5 of the pump. The device is then replaced in an upright position, with the pump 1 placed above the container 2. During this inversion movement, a certain volume 15 of liquid remains inside the cup 6. The retention of liquid at the interior of the cup 6 is partially due to the fact that the reversal movement is fairly rapid. But this liquid retention is also due to capillarity, due to the contact surface of the liquid inside 6a of the cup 6. Advantageously, the inside 6a of the cup 6 can be provided with ribs to increase the surface. of contact between the liquid and the interior 6a of the cup, so as to increase the retention of liquid. Similarly as shown in Figure 4, the pump body 7 may be provided on its part located inside the container 2 with grooves or ribs 50 for retaining a certain amount of liquid during tilting or stirring of the device, this quantity of liquid then flowing along the pump body 7 in the receiving member 6 under the effect of gravity when the device is returned to its upright position. This implementation ensures a transfer of a maximum of product in the cup, especially when there is only a little product left in the container.

Lors de l'actionnement de la pompe, tout ou partie du volume 15 de liquide est aspiré par l'orifice d'entrée 5 de la pompe, qui est plongé dans le volume 15 de liquide.When the pump is actuated, all or part of the volume 15 of liquid is sucked in through the inlet port 5 of the pump, which is immersed in the volume 15 of liquid.

Le volume 15 peut éventuellement correspondre à plusieurs actionnements de la pompe : il peut par exemple correspondre à une dose journalière du produit liquide.The volume 15 can possibly correspond to several actuations of the pump: it can for example correspond to a daily dose of the liquid product.

Lorsque le volume 15 correspond à un seul actionnement de la pompe, et si le dispositif peut être posé en position droite, le dispositif de l'invention peut limiter les utilisations incontrôlées par les enfants, puisqu'il doit être retourné avant d'être utilisé.When the volume 15 corresponds to a single actuation of the pump, and if the device can be placed in an upright position, the device of the invention can limit uncontrolled use by children, since it must be turned over before being used .

Avantageusement, comme représenté sur les figures 6 et 7, le dispositif peut avoir une forme tel qu'il ne puisse être posé en équilibre stable que dans une position inclinée, par exemple sa position inversée. Ainsi, l'organe de rétention du dispositif retient forcément du liquide lorsque l'utilisateur le prend en position droite pour l'actionner. Dans l'exemple de la figure 6, le récipient a une forme conique, et le dispositif comporte en outre un couvercle cylindrique 13 ayant un fond plat 14, qui permet de poser le dispositif en position inversée. Dans l'exemple de la figure 7, le récipient a une forme ovoïde lui permettant d'être posé en position couchée.Advantageously, as shown in FIGS. 6 and 7, the device can have a shape such that it can only be placed in stable equilibrium in an inclined position, for example its inverted position. Thus, the device retention member necessarily retains liquid when the user takes it in an upright position to actuate it. In the example of Figure 6, the container has a conical shape, and the device further comprises a cylindrical cover 13 having a flat bottom 14, which allows to place the device in the inverted position. In the example of Figure 7, the container has an ovoid shape allowing it to be placed in the supine position.

En variante, la pompe 1 des dispositifs décrits sur les figures pourrait éventuellement être remplacée par une valve aérosol.As a variant, the pump 1 of the devices described in the figures could possibly be replaced by an aerosol valve.
