Description

L'invention est relative à un dispositif pour diffuser un produit liquide en fines gouttelettes, du genre de ceux qui comprennent un récipient muni, en partie haute, d'une tête de distribution qui peut être actionnée par enfoncement et qui est susceptible de tourner autour d'un axe parallèle à une direction d'enfoncement, et d'un capot coiffant la tête et le récipient, ce capot comprenant un organe d'actionnement en forme de levier articulé sur l'avant du capot, et comportant un moyen d'appui pour agir sur la tête de distribution, lorsqu'un utilisateur exerce une pression sur la partie arrière du levier, ladite tête de distribution étant déportée vers l'avant du capot par rapport à l'axe du récipient, et comportant une sortie du produit vers l'atmosphère, le capot comportant une ouverture pour le passage du produit diffusé.The invention relates to a device for diffusing a liquid product in fine droplets, of the type which includes a container provided, at the top, with a dispensing head which can be actuated by pressing and which is capable of rotating around an axis parallel to a driving direction, and a cover covering the head and the container, this cover comprising a lever-shaped actuating member articulated on the front of the cover, and comprising a means of support for acting on the dispensing head, when a user exerts pressure on the rear part of the lever, said dispensing head being offset towards the front of the cover relative to the axis of the container, and comprising a product outlet towards the atmosphere, the cover comprising an opening for the passage of the diffused product.

L'invention concerne plus particulièrement, mais non exclusivement, un dispositif dans lequel la tête de distribution constitue l'élément d'actionnement d'une pompe montée sur la partie supérieure du récipient, lequel n'est pas pressurisé lorsque la pompe n'est pas actionnée.The invention relates more particularly, but not exclusively, to a device in which the dispensing head constitutes the actuating element of a pump mounted on the upper part of the container, which is not pressurized when the pump is not not activated.

Il est clair cependant que cette tête de distribution peut être prévue sur un récipient pressurisé et l'enfoncement de la tête aurait alors pour simple effet d'ouvrir une valve, sans actionner une pompe.It is clear, however, that this dispensing head can be provided on a pressurized container and the depression of the head would then have the simple effect of opening a valve, without actuating a pump.

EP-A-0 402 636 montre un dispositif de ce genre, dans lequel toutefois les positions relatives de l'organe d'actionnement, de la tête de distribution et de l'ouverture du capot ne sont pas assurées de manière précise.EP-A-0 402 636 shows a device of this kind, in which, however, the relative positions of the actuating member, of the dispensing head and of the opening of the cover are not precisely ensured.

FR-A-2 517 639 et FR-A-2 524 864 montrent un dispositif pour diffuser un produit liquide contenu dans un récipient pressurisé, comprenant un capot avec organe d'actionnement en forme de levier pour enfoncer une valve. Bien qu'un tel dispositif donne satisfaction pour l'actionnement d'une valve prévue sur un récipient pressurisé, il nécessite de réaliser le levier d'actionnement, muni de conduites internes, sous forme d'une pièce indépendante du capot. Un tel dispositif n'est pas approprié pour actionner une tête de distribution montée sur une pompe manuelle.FR-A-2 517 639 and FR-A-2 524 864 show a device for diffusing a liquid product contained in a pressurized container, comprising a cover with actuating member in the form of a lever for driving a valve. Although such a device gives satisfaction for the actuation of a valve provided on a pressurized container, it requires making the actuation lever, provided with internal conduits, in the form of an independent part of the cover. Such a device is not suitable for actuating a dispensing head mounted on a manual pump.

L'invention a pour but, surtout, de fournir un dispositif qui ne présente plus, ou à un degré moindre, les inconvénients rappelés ci-dessus, et qui soit bien adapté pour la distribution de fines gouttelettes à partir d'un récipient non pressurisé, équipé d'une pompe manuelle, tout en étant simple et d'un prix de revient réduit et dont l'assemblage permet d'assurer et de maintenir un positionnement correct de l'organe d'actionnement, de la tête de distribution et de l'ouverture du capot.The object of the invention is, above all, to provide a device which no longer has, or to a lesser degree, the drawbacks mentioned above, and which is well suited for the distribution of fine droplets from a non-pressurized container , equipped with a manual pump, while being simple and of a reduced cost price and whose assembly makes it possible to ensure and maintain correct positioning of the actuating member, of the dispensing head and of opening the hood.

Selon l'invention, un dispositif pour diffuser un produit liquide en fines gouttelettes, du genre défini précédemment, est caractérisé par le fait que des moyens d'orientation sont prévus entre le capot et le récipient pour imposer un montage du capot relativement au récipient selon une orientation angulaire prédéterminée, de sorte que l'ouverture du capot se trouve au droit de la sortie de la tête de distribution et le moyen d'appui peut agir sur la tête lorsque les différents éléments ont été assemblés selon la position angulaire correcte.According to the invention, a device for diffusing a liquid product in fine droplets, of the kind defined above, is characterized in that orientation means are provided between the cover and the container to impose an assembly of the cover relative to the container according to a predetermined angular orientation, so that the opening of the cover is in line with the outlet of the dispensing head and the support means can act on the head when the different elements have been assembled in the correct angular position.

Les moyens d'orientation entre le capot et le récipient sont constitués, de préférence, par la forme de la section transversale du récipient qui est dissymétrique relativement à l'axe longitudinal du récipient, de telle sorte que le capot ne peut être monté sur ce récipient que selon une seule orientation angulaire.The orientation means between the cover and the container preferably consist of the shape of the cross section of the container which is asymmetrical relative to the longitudinal axis of the container, so that the cover cannot be mounted on this container only in one angular orientation.

La tête de distribution peut comporter une sortie du produit suivant une direction transversale, généralement orthogonale, à la direction d'enfoncement de la tête, et l'ouverture du capot est prévue dans la paroi périphérique de ce capot ; la tête de distribution comporte alors des moyens de positionnement angulaire propres à coopérer avec le moyen d'appui du levier, ce moyen d'appui étant agencé de manière à définir une position angulaire déterminée entre la tête de distribution et le capot.The dispensing head may include an outlet for the product in a transverse direction, generally orthogonal to the driving direction of the head, and the opening of the cover is provided in the peripheral wall of this cover; the dispensing head then includes angular positioning means suitable for cooperating with the lever support means, this support means being arranged so as to define a determined angular position between the dispensing head and the cover.

Les moyens de positionnement angulaire de la tête de distribution peuvent comprendre, du côté de la tête, un gradin prévu sur la surface supérieure de cette tête et, du côté de l'organe d'actionnement, un moyen d'appui formé de plusieurs éléments faisant saillie selon une longueur différente sous cet organe de manière à ne pouvoir coopérer correctement avec la susdite tête que pour une position angulaire déterminée entre la valve et le capot.The angular positioning means of the dispensing head may comprise, on the side of the head, a step provided on the upper surface of this head and, on the side of the actuating member, a support means formed of several elements projecting according to a different length under this member so as to be able to cooperate correctly with the aforesaid head only for a determined angular position between the valve and the cover.

De préférence, le gradin est délimité par une paroi parallèle à la direction d'enfoncement de la tête et à l'axe de l'orifice de sortie de la tête, dirigé sensiblement orthogonalement à la direction d'enfoncement de la tête, ce gradin étant déporté latéralement par rapport à l'axe de la tête.Preferably, the step is delimited by a wall parallel to the direction of insertion of the head and to the axis of the outlet orifice of the head, directed substantially orthogonally to the direction of insertion of the head, this step being offset laterally with respect to the axis of the head.

Les éléments du moyen d'appui, prévus sous l'organe d'actionnement, comprennent avantageusement deux ailettes de hauteur différente, l'ailette la moins haute étant destinée à appuyer sur la tête de distribution, tandis que l'ailette la plus haute est destinée à s'engager contre la paroi du gradin pour imposer l'orientation angulaire convenable de la tête.The elements of the support means, provided under the actuating member, advantageously comprise two fins of different height, the least tallest fin being intended to press on the dispensing head, while the highest fin is intended to engage against the wall of the step to impose the proper angular orientation of the head.

Selon une variante de réalisation, la tête de distribution est munie d'un tube de sortie coaxial à la tête et parallèle à la direction d'enfoncement de la tête, tandis que l'ouverture du capot est ménagée dans l'organe d'actionnement formant levier et est traversée par le tube de sortie qui fait saillie extérieurement.According to an alternative embodiment, the dispensing head is provided with an outlet tube coaxial with the head and parallel to the direction of insertion of the head, while the opening of the cover is provided in the actuating member. forming a lever and is crossed by the outlet tube which projects externally.

La collerette peut comporter des moyens de guidage, en particulier des rainures, propres à coopérer avec les ailettes de l'organe d'actionnement pour maintien de la collerette et du tube de sortie selon une orientation angulaire.The flange may include guide means, in particular grooves, suitable for cooperating with the fins of the actuating member for holding the flange and the outlet tube in an angular orientation.

Selon une autre possibilité, la collerette est sensiblement circulaire, et sa surface supérieure est lisse, la collerette étant agencée pour coopérer avec les ailettes de l'organe d'actionnement quelle que soit l'orientation angulaire du tube de sortie et de la tête de distribution autour de son axe.According to another possibility, the flange is substantially circular, and its upper surface is smooth, the flange being arranged to cooperate with the fins of the actuating member whatever the angular orientation of the outlet tube and of the head. distribution around its axis.

En se reportant aux dessins, notamment à la figure 1, on peut voir un dispositif 1 pour diffuser un produit liquide en fines gouttelettes, ce produit étant contenu dans un récipient 2, ou flacon, généralement en matière plastique. La section transversale du récipient 2 a un contour, visible sur la figure 3, dont la forme est dissymétrique par rapport à un axe longitudinal A du récipient. Cet axe A, selon la figure 1, est vertical ; il passe par le centre d'un cercle tangent à l'extrémité avant et à l'extrémité arrière de la section transversale du récipient. La partie avant du récipient, située sur la gauche selon la représentation des figures 1 et 3, admet une section transversale sensiblement semi-circulaire, tandis que la partie arrière 3 a une section transversale également sensiblement semi-circulaire mais de plus faible rayon ; les deux faces latérales s'étendant entre les parties avant et arrière sont planes et convergent vers l'arrière.Referring to the drawings, in particular to FIG. 1, one can see a device 1 for diffusing a liquid product in fine droplets, this product being contained in a container 2, or bottle, generally made of plastic. The cross section of the container 2 has an outline, visible in Figure 3, whose shape is asymmetrical relative to a longitudinal axis A of the container. This axis A, according to Figure 1, is vertical; it passes through the center of a circle tangent to the front end and the rear end of the cross section of the container. The front part of the container, located on the left according to the representation of FIGS. 1 and 3, has a substantially semi-circular cross section, while the rear part 3 has a cross section also substantially semi-circular but of smaller radius; the two side faces extending between the front and rear parts are flat and converge towards the rear.

Le récipient 2 admet un plan vertical de symétrie V, passant par l'axe A et les arêtes d'extrémité avant et arrière de ce récipient.The container 2 has a vertical plane of symmetry V, passing through the axis A and the front and rear end edges of this container.

Il est à noter que le terme "avant" désigne le côté où se produit la sortie du liquide et que le terme "arrière" désigne le côté opposé.It should be noted that the term "front" designates the side on which the exit of the liquid occurs and that the term "rear" designates the opposite side.

En partie haute, le récipient 2 est équipé d'une tête de distribution 4 constituée, dans l'exemple considéré, par la tête d'une pompe dont le corps est serti en 5 sur une tubulure de sortie 6 du récipient 2. La tubulure 6 ainsi que la tête 4, coaxiale à la tubulure, sont décalées vers l'avant relativement à l'axe A du récipient.In the upper part, the container 2 is equipped with a dispensing head 4 constituted, in the example considered, by the head of a pump, the body of which is crimped at 5 onto an outlet pipe 6 of the container 2. The pipe 6 and the head 4, coaxial with the tubing, are shifted forward relative to the axis A of the container.

Le récipient 2 est muni, en contrebas de la tête 4, d'une gorge d'encliquetage 7.The container 2 is provided, below the head 4, with a latching groove 7.

La tête 4 peut être enfoncée dans le corps de pompe pour provoquer la sortie de liquide finement pulvérisé, par un orifice de sortie 8 prévu latéralement dans cette tête 4, suivant une direction orthogonale à la direction d'enfoncement.The head 4 can be inserted into the pump body to cause the exit of finely atomized liquid, through an outlet orifice 8 provided laterally in this head 4, in a direction orthogonal to the direction of insertion.

La tête 4 peut tourner autour d'un axe B parallèle à la direction d'enfoncement. La partie haute de la tête 4 est dissymétrique par rapport à cet axe B, comme bien visible sur la figure 2. Elle comporte, sur sa surface supérieure, un gradin 9 déterminant deux zones 10, 11 respectivement basse et haute. Le gradin 9 faisant passer d'une zone à l'autre est constitué par une portion de paroi parallèle à l'axe B et à l'axe de l'orifice de sortie 8. Le gradin 9 est déporté latéralement par rapport à l'axe B. La zone 11 peut présenter une légère concavité tournée vers le haut.The head 4 can rotate around an axis B parallel to the driving direction. The upper part of the head 4 is asymmetrical with respect to this axis B, as clearly visible in FIG. 2. It comprises, on its upper surface, a step 9 determining two zones 10, 11 respectively low and high. The step 9 passing from one zone to the other consists of a portion of wall parallel to the axis B and to the axis of the outlet orifice 8. The step 9 is offset laterally relative to the axis B. Zone 11 may have a slight concavity facing upwards.

Le dispositif comprend en outre un capot 12 propre à coiffer le récipient et la tête de distribution en venant s'encliqueter par un bourrelet inférieur 13 dans la gorge 7.The device further comprises a cover 12 suitable for covering the container and the dispensing head while being snapped into place by a lower bead 13 in the groove 7.

Le capot 12, généralement en matière plastique, a une section transversale semblable à celle du récipient 2 de manière à prolonger le corps du récipient lorsque ce capot est en place.The cover 12, generally made of plastic, has a cross section similar to that of the container 2 so as to extend the body of the container when this cover is in place.

Le capot 12 est équipé d'un organe d'actionnement de la valve de distribution, constitué par un levier 14.The cover 12 is equipped with an actuating member of the dispensing valve, constituted by a lever 14.

Ce levier 14 a la forme d'un dièdre droit admettant une face supérieure 15 horizontale, lorsque le récipient 2 est vertical, et une face arrière 16 verticale. Les deux faces sont réunies par une surface convexe vers l'extérieur r. La face supérieure 15 est plane tandis que la face arrière 16 est sensiblement semi-cylindrique de manière à s'inscrire dans le contour intérieur de la face arrière 17 du capot, qui est semblable à la face arrière 3 du récipient.This lever 14 has the shape of a right dihedral admitting an upper horizontal face 15, when the container 2 is vertical, and a rear rear face 16 vertical. The two faces are joined by an outwardly convex surface r . The upper face 15 is flat while the rear face 16 is substantially semi-cylindrical so as to fit into the inner contour of the rear face 17 of the cover, which is similar to the rear face 3 of the container.

Les faces 15 et 16 sont comprises entre deux parois 18, 19 planes convergeant légèrement vers l'arrière et sensiblement tangentes, intérieurement, aux parois latérales du capot. Les parois 18 et 19 s'étendent jusqu'au bord inférieur de la face arrière 16, mais s'arrêtent à une certaine distance en arrière du bord avant 20 de la face supérieure 15. Ces parois latérales 18, 19 sont limitées par un bord 21 en arc de cercle.The faces 15 and 16 are between two planar walls 18, 19 converging slightly towards the rear and substantially tangent, internally, to the side walls of the cover. The walls 18 and 19 extend to the lower edge of the rear face 16, but stop at a certain distance behind the front edge 20 of the upper face 15. These side walls 18, 19 are limited by an edge 21 in an arc.

Le capot 12 comporte à sa partie arrière, vers le haut, une échancrure limitée par un contour 22 sensiblement en arc de cercle, situé légèrement au-dessus du bord 21 lorsque le levier 14 est en position de repos. Cette échancrure permet de laisser apparente la majeure partie du levier-poussoir 14 qui complète sensiblement le contour du capot 12 au niveau de cette échancrure.The cover 12 has, at its rear part, upwards, a notch limited by a contour 22 substantially in an arc, situated slightly above the edge 21 when the lever 14 is in the rest position. This notch makes it possible to leave the bulk of the push-button 14 visible, which substantially completes the outline of the cover 12 at this notch.

Le levier 14 est articulé, au niveau de la partie centrale de son bord avant 20, sur la paroi avant du capot 12, de préférence par une charnière-film 23 (voir figure 3), ce qui permet de mouler d'une seule pièce le capot 12 et le levier 14.The lever 14 is articulated, at the central part of its front edge 20, on the front wall of the cover 12, preferably by a film hinge 23 (see FIG. 3), which makes it possible to mold in one piece the cover 12 and the lever 14.

Le levier 14 comporte, sous sa face supérieure 15, un moyen d'appui P pour exercer une pression sur la tête 4 et enfoncer la valve de distribution.The lever 14 has, under its upper face 15, a support means P for exerting pressure on the head 4 and pressing the dispensing valve.

Le moyen d'appui P comprend deux ailettes 24, 25 de hauteur différente, orthogonales à la face 15 et parallèles au plan V. L'ailette la moins haute 24 a la forme d'un demi-cercle tournant sa convexité vers le bas et admet comme plan moyen le plan V. Cette ailette 24 est destinée à appuyer contre la zone supérieure 11 de la tête 4.The support means P comprises two fins 24, 25 of different height, orthogonal to the face 15 and parallel to the plane V. The least tallest fin 24 has the shape of a semicircle turning its convexity downwards and accepts plane V as medium plane. This fin 24 is intended to press against the upper zone 11 of the head 4.

L'autre ailette 25 plus haute, décalée transversalement par rapport à l'ailette 24, est destinée à s'engager contre la paroi du gradin 9 pour imposer l'orientation angulaire convenable de la tête 4. Cette ailette 25 a une forme sensiblement trapézoïdale. Lorsque son plan est en appui latéral contre le gradin 9, lui-même plan, l'axe de l'orifice de sortie 8 est situé dans le plan vertical V de symétrie.The other higher fin 25, offset transversely with respect to the fin 24, is intended to engage against the wall of the step 9 to impose the suitable angular orientation of the head 4. This fin 25 has a substantially trapezoidal shape . When its plane is in lateral support against the step 9, itself plane, the axis of the outlet orifice 8 is located in the vertical plane V of symmetry.

Le capot 12 comporte, dans sa paroi périphérique avant, une ouverture 26 de forme sensiblement rectangulaire à extrémités arrondies, dont la grande dimension est orientée verticalement. Cette ouverture admet le plan V comme plan de symétrie et se trouve en face de l'orifice de sortie 8 lorsque les différents éléments ont été assemblés dans la position angulaire correcte.The cover 12 has, in its front peripheral wall, an opening 26 of substantially rectangular shape with rounded ends, the large dimension of which is oriented vertically. This opening admits the plane V as the plane of symmetry and is located opposite the outlet orifice 8 when the various elements have been assembled in the correct angular position.

Le capot 12 comprend, à l'arrière, un moyen d'accrochage C de la partie arrière du levier 14 pour bloquer ce levier en position de repos et empêcher toute action sur la tête 4 ; l'échappement du levier vis-à-vis de ce moyen d'accrochage C est obtenu par une légère déformation, sous l'action d'une poussée, de la paroi arrière 16 du levier.The cover 12 comprises, at the rear, a hooking means C for the rear part of the lever 14 to block this lever in the rest position and prevent any action on the head 4; the lever escapement with respect to this hooking means C is obtained by a slight deformation, under the action of a push, of the rear wall 16 of the lever.

Le moyen d'accrochage C est avantageusement constitué par un bec 27 prévu sur la surface interne de la paroi arrière 17 du capot, en partie haute, propre à coopérer avec le bord inférieur de la face arrière 16 du levier 14.The attachment means C is advantageously constituted by a spout 27 provided on the internal surface of the rear wall 17 of the cover, in the upper part, adapted to cooperate with the lower edge of the rear face 16 of the lever 14.

Le montage du capot sur le récipient 2 et le fonctionnement du dispositif résultent immédiatement des explications qui précèdent.The mounting of the cover on the container 2 and the operation of the device immediately result from the foregoing explanations.

La forme dissymétrique de la section transversale du récipient 2 , et de la section transversale correspondante du capot 12 ne permet le montage du capot sur le récipient que selon une orientation angulaire déterminée, l'ouverture 26 se trouvant vers l'avant et la face 16 du levier se trouvant vers l'arrière. Cette forme de la section transversale du récipient et du capot constitue donc un moyen d'orientation entre le capot et le récipient.The asymmetrical shape of the cross section of the container 2, and of the corresponding cross section of the cover 12 allows the mounting of the cover on the container only according to a determined angular orientation, the opening 26 being towards the front and the face 16 lever located towards the rear. This shape of the cross section of the container and the cover therefore constitutes a means of orientation between the cover and the container.

En outre, le capot ne peut être mis correctement en place sur le récipient que si la tête 4 est correctement orientée avec l'axe de son orifice de sortie 8 situé dans le plan vertical V afin que l'ailette 25 puisse s'engager contre le gradin 9. Le gradin 9 constitue donc un moyen de positionnement angulaire de la tête 4 coopérant avec le moyen d'appui P du levier qui comprend l'ailette 25.In addition, the cover can only be correctly placed on the container if the head 4 is correctly oriented with the axis of its outlet orifice 8 located in the vertical plane V so that the fin 25 can engage against the step 9. The step 9 therefore constitutes a angular positioning means for the head 4 cooperating with the support means P of the lever which comprises the fin 25.

Le montage étant ainsi réalisé, l'orifice de sortie 8 se trouve en face de l'ouverture 26. La tête 4 ne peut plus tourner autour de l'axe B.The assembly being thus produced, the outlet orifice 8 is located opposite the opening 26. The head 4 can no longer rotate about the axis B.

Pour actionner le dispositif et obtenir une pulvérisation, il suffit d'appuyer sur la partie arrière de la surface supérieure 15 du levier 14 pour enfoncer la tête 4.To activate the device and obtain a spray, it suffices to press the rear part of the upper surface 15 of the lever 14 to depress the head 4.

Les figures 4 à 6 montrent une variante de réalisation dont les éléments identiques ou jouant des rôles équivalents à des éléments déjà décrits à propos des figures précédentes sont désignés par une référence numérique égale à la somme du nombre 100 et de la référence utilisée précédemment. La description de ces éléments ne sera pas reprise, ou ne sera effectuée que succinctement.Figures 4 to 6 show an alternative embodiment of which the identical elements or playing roles equivalent to elements already described with respect to the previous figures are designated by a numerical reference equal to the sum of the number 100 and the reference used previously. The description of these elements will not be repeated, or will only be done briefly.

La tête de distribution 104 est munie d'un tube de sortie 28 coaxial à la tête, et parallèle à la direction d'enfoncement de la tête. Le tube 28 peut être tronconique extérieurement et diminuer de diamètre extérieur dans le sens qui éloigne de la tête 104. Le tube 28 comporte un passage interne 108 de section circulaire constante.The dispensing head 104 is provided with an outlet tube 28 coaxial with the head, and parallel to the driving direction of the head. The tube 28 can be frustoconical on the outside and decrease in external diameter in the direction which moves away from the head 104. The tube 28 has an internal passage 108 of constant circular section.

L'ouverture 126 du capot 112 est ménagée, non plus dans la paroi périphérique qui est continue, mais dans la partie supérieure du capot formée par l'organe d'actionnement ou levier 114. L'ouverture 126 est circulaire et a un diamètre supérieur à celui de la partie du tube 28 traversant cette ouverture et faisant saillie au-delà du levier 114. Le diamètre de l'ouverture 126 est suffisant pour permettre les débattements du levier 114, sans qu'il y ait interférence avec le tube 28.The opening 126 of the cover 112 is made, no longer in the peripheral wall which is continuous, but in the upper part of the cover formed by the actuating member or lever 114. The opening 126 is circular and has a larger diameter to that of the part of the tube 28 passing through this opening and projecting beyond the lever 114. The diameter of the opening 126 is sufficient to allow the deflections of the lever 114, without there being any interference with the tube 28.

Le tube 28 est équipé, à sa base, d'une collerette 29 entourant le tube dont elle est solidaire et contre laquelle prennent appui les ailettes 124, 125, de même hauteur, du levier 114. Les ailettes 124, 125 sont disposées de part et d'autre du tube 28. Dans l'exemple de réalisation des figures 4 à 6, la collerette 29 a une forme ovale ou sensiblement elliptique, dont le grand axe est destiné à être placé perpendiculairement au plan vertical de symétrie V du récipient, plan dont la trace sur la figure 6 correspond à la ligne IV-IV. La collerette 29 comporte des moyens de guidage, avantageusement formés par des rainures 30, 31 prévus sur sa surface supérieure, propres à coopérer avec les ailettes 124, 125 pour maintenir la collerette 29 dans la position illustrée sur la figure 6. La base des ailettes 124, 125, lorsque la position de la collerette 29 est correcte, est reçue respectivement dans les rainures 30, 31.The tube 28 is equipped, at its base, with a flange 29 surrounding the tube of which it is integral and against which the fins 124, 125 bear, of the same height, of the lever 114. The fins 124, 125 are arranged on the side and on the other side of the tube 28. In the embodiment of FIGS. 4 to 6, the flange 29 has an oval or substantially elliptical shape, the major axis of which is intended to be placed perpendicular to the vertical plane of symmetry V of the container, plan whose trace on figure 6 corresponds to line IV-IV. The flange 29 comprises guide means, advantageously formed by grooves 30, 31 provided on its upper surface, capable of cooperating with the fins 124, 125 to maintain the flange 29 in the position illustrated in FIG. 6. The base of the fins 124, 125, when the position of the flange 29 is correct, is received in the grooves 30, 31 respectively.

Avantageusement, du fait qu'avec la disposition de la figure 4, la rotation du tube de sortie 28 autour de son axe n'est pas gênante, on peut s'affranchir de la présence de rainures 30, 31. Comme illustré sur la figure 7, on peut agencer la tête 104 avec une collerette 29a, circulaire ou sensiblement circulaire, ayant un diamètre au moins égal à la distance entre les faces extérieures des ailettes 124, 125. Ainsi, quelle que soit l'orientation angulaire du tube 28 autour de son axe, il y aura toujours coopération des ailettes 124, 125 et de la collerette 29a, et donc actionnement de la tête 104 par le levier 114.Advantageously, the fact that with the arrangement of FIG. 4, the rotation of the outlet tube 28 around its axis is not a problem, it is possible to dispense with the presence of grooves 30, 31. As illustrated in the figure 7, the head 104 can be arranged with a flange 29 a circular or substantially circular, having a diameter at least equal to the distance between the outer faces of the fins 124, 125. Thus, regardless of the angular orientation of tube 28 around its axis, there will always be cooperation between the fins 124, 125 and the flange 29 a , and therefore actuation of the head 104 by the lever 114.

Le dispositif conforme à l'invention présente un certain nombre d'avantages.The device according to the invention has a number of advantages.

Il permet d'obtenir une pulvérisation directionnelle. Le point d'appui du levier, pour l'utilisateur, situé à l'arrière permet d'obtenir une grande souplesse d'utilisation, assurant ainsi une pulvérisation fine grâce à l'éjection complète de la dose précomprimée. La pression exercée sur la tête est toujours orientée suivant l'axe B de cette tête. La qualité des produits diffusés s'en trouve ameliorée.It provides a directional spray. The fulcrum of the lever, for the user, located at the rear provides great flexibility of use, thus ensuring fine spraying thanks to the complete ejection of the precompressed dose. The pressure exerted on the head is always oriented along the axis B of this head. The quality of the products distributed is improved.

Ce dispositif est ergonomique, notamment en raison de la forme de la section transversale du bouton-poussoir et du flacon, et permet ainsi une utilisation prolongée sans effort.This device is ergonomic, in particular due to the shape of the cross section of the push button and of the bottle, and thus allows prolonged use without effort.

Ce dispositif peut être utilisé avec des ongles longs, avec le pouce ou l'index, en étant tenu d'une seule main, que l'on soit droitier ou gaucher.This device can be used with long nails, with the thumb or forefinger, being held with one hand, whether one is right-handed or left-handed.

Le dispositif d'accrochage, formé par le bec 27, 127 constitue un système d'ouverture/fermeture invisible.The attachment device, formed by the spout 27, 127 constitutes an invisible opening / closing system.

Le dispositif diffuseur selon l'invention sera livré en position de fermeture, c'est-à-dire levier 14, 114 accroché sur le bec 27, 127. Il suffira d'une simple pression sur la face arrière 16, 116 pour placer le dispositif en position de fonctionnement. Pour revenir à la position "fermée", par exemple en cas de transport du dispositif au cours d'un voyage, il suffit de remonter légèrement le capot 14, 114 pour assurer l'accrochage sur le bec 27, 127.The diffuser device according to the invention will be delivered in the closed position, that is to say lever 14, 114 hung on the spout 27, 127. It will suffice with a simple pressure on the rear face 16, 116 to place the device in operating position. To return to the "closed" position, for example in the event of transport of the device during a trip, it suffices to slightly raise the cover 14, 114 to ensure the attachment to the spout 27, 127.
