Abstract

The invention concerns a fluid product dispenser comprising: a fluid product container (12) defining at least one actuating wall (21) adapted to be mobile, a dispensing orifice (41), and spring means (7) adapted to urge the actuating wall into a state of maximum container volume. The invention is characterized in that the spring means (7) co-operate with cocking means (11) adapted to cause the spring means to urge the actuating wall from an initial state wherein the spring means do not urge the actuating wall.

Description

La présente invention concerne un distributeur de produit fluide comprenant un réservoir de produit fluide définissant une paroi d'actionnement déplaçable et ou déformable apte à être déplacée ou enfoncée, un orifice de distribution et des moyens de ressort adaptés à solliciter la paroi déformable dans un état de volume maximal du réservoir. Le distributeur, ou au moins le réservoir peut par exemple être réalisé à partir d'une ou de deux feuilles souples formant la paroi d'actionnement. Par enfoncement de la paroi d'actionnement à l'encontre des moyens de ressort, on diminue le volume interne du réservoir et du produit fluide est ainsi refoulé à travers l'orifice de distribution. Il s'agit là d'une conception classique pour un distributeur dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie. Dans certains domaines, il est avantageux que la distribution s'effectue sous la forme d'une pulvérisation.The present invention relates to a fluid dispenser comprising a fluid reservoir defining a displaceable and deformable actuating wall capable of being moved or depressed, a dispensing orifice and spring means adapted to urge the deformable wall into a state. maximum volume of the tank. The dispenser, or at least the reservoir may for example be made from one or two flexible sheets forming the actuating wall. By depressing the actuating wall against the spring means, the internal volume of the reservoir is reduced and the fluid product is thus discharged through the dispensing orifice. This is a classic design for a distributor in the field of perfumery, cosmetics or pharmacy. In some areas, it is advantageous that the distribution takes place in the form of a spray.

Dans le cas où la paroi d'actionnement est déformable, les moyens de ressort agissent sur la paroi en la déformant vers un état de déformation maximale dans laquelle elle définit un état de volume maximal pour le réservoir. La déformation de la paroi déformable du fait des moyens de ressort n'est pas toujours esthétique et peut de ce fait nuire à l'aspect du distributeur. De plus, les moyens de ressort augmentent l'épaisseur totale du distributeur ce qui peut être un inconvénient majeur dans certains cas d'utilisation.In the case where the actuating wall is deformable, the spring means act on the wall by deforming it to a state of maximum deformation in which it defines a state of maximum volume for the tank. The deformation of the deformable wall due to the spring means is not always aesthetic and can therefore adversely affect the appearance of the dispenser. In addition, the spring means increase the total thickness of the dispenser which can be a major drawback in some cases of use.

En effet, on connaît du document FR-2 791 645 un distributeur selon le préambule de la revendication 1, dont l'orifice de distribution est obturé avant utilisation par un organe d'obturation amovible. L'intérieur du réservoir ne communique donc pas avec l'extérieur et, selon ce document, le ressort qui agit sur une paroi déformable est comprimé à un état maximal, de sorte que l'épaisseur du distributeur peut être maintenu à un minimum. Ceci est une exigence primordiale lorsque l'on veut inclure un tel distributeur dans des magazines sous la forme d'échantillon de produit fluide. Même lorsque l'orifice de distribution est obturé, le ressort agit bien évidemment sur la paroi déformable, ce qui déforme inesthétiquement la paroi déformable qui présente alors un relief souvent irrégulier.Indeed, we know of the document FR-2 791 645 a dispenser according to the preamble of claim 1, the dispensing orifice is closed before use by a removable closure member. The interior of the tank therefore does not communicate with the outside and, according to this document, the spring acting on a deformable wall is compressed to a maximum state, so that the thickness of the distributor can be kept to a minimum. This is a primary requirement when one wants to include such a dispenser in magazines in the form of fluid sample. Even when the dispensing orifice is closed, the spring acts obviously on the deformable wall, which uninhabitably deforms the deformable wall which then has an often irregular relief.

On connaît aussi des distributeurs de l'art antérieur dont la paroi d'actionnement n'est pas déformable, mais juste déplaçable.Distributors of the prior art are also known whose operating wall is not deformable, but just displaceable.

La présente invention a pour but de remédier à cet inconvénient précité de l'art antérieur en définissant un distributeur de produit fluide dont les moyens de ressort ne nuisent pas à l'esthétique de la paroi d'actionnement, au moins avant utilisation du distributeur. Un autre but est de pouvoir armer les moyens de ressort d'une manière pratique, rapide, et de préférence intuitive.The present invention aims to overcome this disadvantage of the prior art by defining a fluid dispenser whose spring means do not affect the aesthetics of the actuating wall, at least before use of the dispenser. Another object is to be able to arm the spring means in a practical manner, fast, and preferably intuitive.

Pour atteindre ces buts, la présente invention prévoit que les moyens de ressort coopèrent avec des moyens d'armement aptes à amener les moyens de ressort en sollicitation de la paroi d'actionnement à partir d'un état initial dans lequel les moyens de ressort ne sollicitent pas la paroi d'actionnement, les moyens de ressort comprenant une plaque avant et une plaque arrière , le réservoir étant situé entre les plaques avant et arrière, les moyens d'armement comprenant des moyens d'entretoise étant sélectivement déplaçables entre une position inopérante dans laquelle les deux plaques s'étendent sensiblement parallèlement correspondant à un état de volume minimal du réservoir et une position opérante dans laquelle les plaques sont éloignées au moins localement l'une de l'autre, la plaque avant étant déplaçable par rapport à la plaque arrière de manière à écraser le réservoir situé entre elles, des moyens d'actionnement étant prévus pour positionner les moyens d'entretoise entre les deux plaques de manière à les éloigner, les moyens d'actionnement comprenant un organe de traction pourvu d'une extrémité de fixation reliée aux moyens d'entretoise et d'une extrémité de traction, l'extrémité de traction étant située à proximité de l'orifice de distribution.To achieve these objects, the present invention provides that the spring means cooperate with arming means able to bring the spring means into solicitation of the actuating wall from an initial state in which the spring means do not do not bias the actuating wall, the spring means comprising a front plate and a back plate, the reservoir being located between the front and rear plates, the arming means comprising spacer means being selectively movable between an inoperative position wherein the two plates extend substantially parallel corresponding to a state of minimum volume of the reservoir and an operative position in which the plates are at least locally spaced from each other, the front plate being movable relative to the plate back so as to crush the reservoir located between them, actuating means being provided for positioning the spacer means between the two plates so as to move them apart, the actuating means comprising a traction member provided with an attachment end connected to the spacer means and a pulling end, the pulling end being located near the dispensing orifice.

Ainsi, les moyens de ressort n'agissent pas sur la paroi d'actionnement dans l'état initial et on se sert des moyens d'armement pour conférer aux moyens de ressort leur fonction véritable et souhaitée, c'est-à-dire de sollicitation de la paroi d'actionnement. Le distributeur de l'invention peut par conséquent être stocké avant utilisation dans un état dans lequel les moyens de ressort n'agissent pas sur la paroi d'actionnement. En l'absence de sollicitation, la paroi d'actionnement reste sans contrainte et peut ainsi présenter un aspect esthétique convenable. La paroi d'actionnement, et ainsi le distributeur, peut alors rester dans un état parfaitement plat, apte à être utilisée en tant qu'échantillon dans les magazines.Thus, the spring means do not act on the actuating wall in the initial state and the arming means are used to give the spring means their true and desired function, that is to say of solicitation of the actuating wall. The dispenser of the invention can therefore be stored before use in a state in which the spring means does not act. not on the actuating wall. In the absence of stress, the actuating wall remains unconstrained and can thus have a suitable aesthetic appearance. The actuating wall, and thus the dispenser, can then remain in a perfectly flat state, suitable for use as a sample in magazines.

Selon un aspect de l'invention, l'orifice de distribution est obturé par un organe d'obturation amovible solidaire de l'organe de traction. En variante, l'orifice de distribution est obturé par un organe d'obturation amovible pourvu d'une languette de préhension, l'extrémité de traction étant formée par ladite languette de préhension.According to one aspect of the invention, the dispensing orifice is closed by a removable closure member integral with the traction member. Alternatively, the dispensing orifice is closed by a removable closure member provided with a gripping tab, the pulling end being formed by said gripping tab.

Le fait que l'extrémité de traction soit située à proximité directe de l'orifice de distribution permet une compréhension rapide et même intuitive de l'utilisation du distributeur, car il est tout à fait naturel de retirer l'organe d'obturation d'un distributeur en tirant sur une languette qui lui est associée. L'utilisateur croit uniquement ôter l'organe d'obturation, et en réalité il actionne également les moyens d'armement. En d'autres termes, l'actionnement des moyens d'armement est complètement masqué par le retrait de l'organe d'obturation.The fact that the pulling end is located in the direct vicinity of the dispensing orifice allows a rapid and even intuitive understanding of the use of the dispenser, since it is quite natural to remove the shutter member from the dispenser. a distributor pulling on a tab associated with it. The user only thinks to remove the shutter member, and in fact it also actuates the arming means. In other words, the actuation of the arming means is completely hidden by the removal of the shutter member.

Selon une autre caractéristique de l'invention, les moyens d'entretoise et les moyens de commande sont réalisés de manière monobloc. Avantageusement, lequel les moyens d'entretoise comprennent un rabat articulé déplaçable entre les positions inopérante et armée, ledit rabat et l'organe de traction étant réalisés de manière monobloc.According to another characteristic of the invention, the spacer means and the control means are made integrally. Advantageously, the spacer means comprise an articulated flap movable between the inoperative and armed positions, said flap and the traction member being made integrally.

D'autre part, l'organe de traction peut s'étendre entre les deux plaques.On the other hand, the traction member may extend between the two plates.

Selon une forme de réalisation pratique, l'organe de traction forme un étrier comprenant deux branches reliées ensemble par une âme commune, les deux branches définissant deux extrémités de liaison formant ensemble ladite extrémité de fixation. Avantageusement, l'organe de traction comprend une patte reliée à l'âme, ladite patte définissant une extrémité libre reliée à ou formant l'extrémité de traction. Avantageusement, la patte est détachable de l'étrier. Plus généralement, l'extrémité de traction est détachable du restant de l'organe de traction.According to a practical embodiment, the traction member forms a stirrup comprising two branches connected together by a common core, the two branches defining two connecting ends together forming said fixing end. Advantageously, the traction member comprises a tab connected to the core, said tab defining a free end connected to or forming the pulling end. Advantageously, the tab is detachable from stirrup. More generally, the pulling end is detachable from the remainder of the traction member.

Selon un autre aspect, le réservoir est fixé à une plaque entre les deux branches de l'étrier.In another aspect, the reservoir is attached to a plate between the two arms of the caliper.

D'autre part, les moyens de ressort sont formés par au moins un parmi la plaque avant, la plaque arrière et les moyens d'entretoise.On the other hand, the spring means is formed by at least one of the front plate, the back plate and the spacer means.

Selon une caractéristique pratique, le réservoir ne contient presque que du produit fluide avant retrait de l'organe d'obturation amovible.According to a practical feature, the reservoir contains almost only fluid before removal of the removable closure member.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation d'un distributeur selon l'invention.The invention will now be further described with reference to the accompanying drawings giving by way of non-limiting example an embodiment of a dispenser according to the invention.

  • the figure 2 is a partial perspective view of the other side of the distributor of the figure 1 ,
  • the Figures 3, 4 and 5 are vertical cross-sectional views through the distributor of the Figures 1 and 2 , respectively in the rest position, armed and actuated, and

Le distributeur comprend une poche de produit fluide liquide ou pulvérulent 3, qui est ici réalisée à partir d'une feuille souple déformable 31 repliée sur elle-même et fixée de manière étanche sur la périphérie. La fixation étanche des deux feuilles peut être avantageusement réalisée par thermosoudage. On définit ainsi un réservoir de produit fluide 30 de volume variable. La feuille souple 31 forme une paroi d'actionnement déformable ou enfonçable. Le distributeur comprend également un orifice de distribution 321 qui peut être ici de préférence un orifice de pulvérisation. Cet orifice est de préférence formé par tête de distribution 32 en matière plastique rigide qui définit un canal de sortie dont l'extrémité aval forme l'orifice de distribution. La feuille 31 est avantageusement soudée sur la tête de distribution. L'orifice 321 est avantageusement obturé au moins avant la première utilisation par un organe d'obturation amovible qui comprend une partie d'obturation 341 et une partie d'accrochage 342.The dispenser comprises a liquid or powder fluid bag 3, which is here made from a deformable flexible sheet 31 folded on itself and sealingly attached to the periphery. The sealed attachment of the two sheets can be advantageously carried out by heat sealing. This defines a fluid reservoir 30 of variable volume. The flexible sheet 31 forms a deformable or sinking actuating wall. The dispenser also includes a dispensing orifice 321 which may preferably be a spray orifice. This orifice is preferably formed by dispensing head 32 of rigid plastic material which defines an outlet channel whose downstream end forms the dispensing orifice. Sheet 31 is advantageously welded to the dispensing head. The orifice 321 is advantageously closed at least before the first use by a removable closure member which comprises a sealing portion 341 and a fastening portion 342.

Ainsi, après avoir retiré l'organe d'obturation amovible de l'orifice de distribution, on peut appuyer sur la feuille, ce qui diminue le volume utile du réservoir 30 et le produit fluide stocké dans le réservoir est alors refoulé à travers le canal et l'orifice de distribution. Avantageusement, le réservoir comprend une pièce de matière poreuse apte à s'imbiber ou à s'imprégner de produit fluide liquide ou pulvérulent. De préférence, cette pièce est positionnée au contact direct de l'orifice de distribution 321 ou le canal de sortie.Thus, after removing the removable closure member from the dispensing orifice, it is possible to press on the sheet, which reduces the useful volume of the reservoir 30 and the fluid product stored in the reservoir is then discharged through the channel and the dispensing orifice. Advantageously, the reservoir comprises a piece of porous material capable of imbibing or impregnating liquid or powdery fluid product. Preferably, this part is positioned in direct contact with the dispensing orifice 321 or the outlet channel.

Le distributeur comprend également des moyens de ressort et d'armement qui se présentent ici sous la forme d'une plaque supérieure 2 et d'une plaque inférieure 1, associées à un rabat pivotant 42 et un organe de traction 43 pour faire pivoter le rabat. Le rabat 42 remplit une fonction de moyens d'armement permettant d'activer les moyens de ressort. Il peut également assurer une fonction de ressort. Au moins une des deux plaques est élastiquement déformable, de manière à remplir une fonction de ressort, si le rabat ne la remplit pas déjà. De préférence, les deux plaques sont élastiquement déformables et le rabat est rigide. Les deux plaques 1 et 2 peuvent être réalisées à partir d'un morceau de plaque unique relié par un pli de liaison 12, comme c'est le cas sur les figures. Une découpe ou échancrure 21 est formée au niveau du pli de liaison 12. L'échancrure peut être réalisée par une fenêtre qui s'étend à cheval sur le pli et qui est ensuite repliée sur elle-même. L'orifice de distribution 321 avec son organe d'obturation amovible sont positionnés dans cette échancrure 21.The dispenser also comprises spring and arming means which are here in the form of an upper plate 2 and a lower plate 1, associated with a pivot flap 42 and a pulling member 43 for pivoting the flap. . The flap 42 performs a function of arming means for activating the spring means. It can also provide a spring function. At least one of the two plates is elastically deformable, so as to fulfill a spring function, if the flap does not fill already. Preferably, the two plates are elastically deformable and the flap is rigid. The two plates 1 and 2 can be made from a single piece of plate connected by a connecting fold 12, as is the case in the figures. A cutout or notch 21 is formed at the binding fold 12. The recess can be made by a window which straddles the fold and which is then folded on itself. The dispensing orifice 321 with its removable closure member are positioned in this indentation 21.

La plaque 1 est formée par un pan 10 et deux volets latéraux 11qui sont repliables sur le pan. La plaque 2 est reliée au pan 10 par le pli 12. La plaque a sensiblement la même taille que le pan 10, de sorte qu'ils peuvent se superposer.The plate 1 is formed by a pan 10 and two side flaps 11 which are foldable on the pan. The plate 2 is connected to the pan 10 by the fold 12. The plate is substantially the same size as the pan 10, so they can be superimposed.

Un talon de fixation 41 est avantageusement collé sur le pan 10. Le talon peut aussi être réalisé d'une seule pièce avec la plaque 1. Le rabat 42 être articulé par rapport au talon 41 par pivotement autour d'une ligne 412. Le rabat va servir de moyens d'armement sous la forme de moyens d'entretoise, comme on le verra ci-après. Le rabat est en outre pourvu d'une petite languette de blocage 422 dont la fonction sera expliquée ci-après. Le talon et le rabat peuvent être réalisés d'une seule pièce. Le rabat est avantageusement situé à proximité du bord opposé au pli 12.A fixing heel 41 is advantageously glued on the panel 10. The heel can also be made in one piece with the plate 1. The flap 42 is articulated relative to the heel 41 by pivoting about a line 412. The flap will serve arming means in the form of spacer means, as will be seen hereinafter. The flap is further provided with a small locking tab 422 whose function will be explained below. The heel and the flap can be made in one piece. The flap is advantageously located near the edge opposite the fold 12.

Quant à la plaque 2, elle est formée avec une fente 22 destinée à recevoir la languette de blocage 422 de la plaque 1.As for the plate 2, it is formed with a slot 22 intended to receive the locking tongue 422 of the plate 1.

Les plaques sont destinées à être fixées, avantageusement thermosoudées, ensemble au niveau des volets 11. On obtient ainsi une sorte d'enveloppe scellée sur trois côtés et ouvert sur le côté où est formé le rabat articulé 42. La poche souple 3 est disposée entre les deux plaques à l'intérieur de l'enveloppe qu'elles forment ensemble. L'orifice de distribution 321 est positionné avantageusement de manière centrale au niveau de l'échancrure 21. La poche 23 peut avantageusement être fixée à l'intérieur de l'enveloppe constituée par les deux plaques. La poche peut par exemple être fixée en deux points 311 et 312 à chacune des plaques.The plates are intended to be fixed, advantageously heat-sealed, together at the level of the flaps 11. This gives a kind of envelope sealed on three sides and open on the side where is formed the hinged flap 42. The flexible bag 3 is disposed between the two plates inside the envelope they form together. The dispensing orifice 321 is advantageously positioned centrally at the notch 21. The pocket 23 may advantageously be fixed inside the envelope constituted by the two plates. The pocket may for example be fixed at two points 311 and 312 to each of the plates.

Lorsque le rabat 42 s'étend dans le même plan que le restant de la plaque 1, comme représenté sur les figures 1 et 3, la plaque 2 s'étend sensiblement parallèlement à la plaque 1, avec la poche souple 3 intercalée entre elles. La poche souple 3 ne contient avantageusement que très peu de produit fluide, de sorte qu'elle peut présenter une configuration particulièrement plate. Ainsi, lorsque disposée entre les deux plaques 1 et 2, elle ne crée qu'une faible surépaisseur, et ainsi les deux plaques semblent être superposées avec presque rien entre elles. Ceci est représenté sur la figure 3. L'épaisseur cumulée du distributeur peut être de l'ordre de 2 à 3 mm. Le distributeur est alors dans un état de repos approprié pour son transport et son stockage. La poche souple 3, qui forme les parois d'actionnement, n'est soumise à aucune contrainte. De même, les plaques 1 et 2 ne sont soumises à aucune contrainte.When the flap 42 extends in the same plane as the remainder of the plate 1, as shown in FIGS. figures 1 and 3 , the plate 2 extends substantially parallel to the plate 1, with the flexible bag 3 interposed between them. The flexible bag 3 advantageously contains only very little fluid, so that it can have a particularly flat configuration. Thus, when arranged between the two plates 1 and 2, it creates only a small extra thickness, and thus the two plates seem to be superimposed with almost nothing between them. This is represented on the figure 3 . The cumulative thickness of the distributor may be of the order of 2 to 3 mm. The dispenser is then in a state of rest appropriate for its transport and its storage. The flexible bag 3, which forms the actuating walls, is not subject to any constraint. Similarly, the plates 1 and 2 are not subject to any stress.

Pour armer le distributeur, il suffit de faire pivoter le rabat 42 autour de la ligne d'articulation 412 en direction de la plaque 2, comme cela est représenté par la petite flèche sur la figure 4. La ligne de pliage 412 est avantageusement réalisée de manière courbe, par exemple en forme d'arc de cercle. De manière symétrique, le bord du rabat où est formée la languette peut également être réalisé de manière courbe. Ainsi, lorsque le rabat 42 pivote en direction de la plaque 2, les plaques prennent une courbure correspondant à la ligne de pliage et au bord libre. Le rabat est articulé par pivotement jusqu'à ce que son bord libre vienne en appui sur la plaque 2 et sa petite languette de blocage 422 vienne se loger à l'intérieur de la fenêtre 22 formée dans la plaque 2. Ceci est représenté sur la figure 4. Le rabat s'étend alors de manière sensiblement perpendiculaire, à la fois à la plaque 71 et à la plaque 2. Du fait de l'engagement de la languette 422 dans la fenêtre 22, le rabat est bloqué en position. Le rabat peut par exemple être réalisé de manière rigide. Il constitue ainsi des moyens d'entretoise qui permettent de maintenir les deux plaques éloignées l'une de l'autre.To arm the dispenser, simply rotate the flap 42 around the hinge line 412 towards the plate 2, as shown by the small arrow on the figure 4 . The folding line 412 is advantageously performed in a curved manner, for example in the form of a circular arc. In a symmetrical manner, the edge of the flap where the tongue is formed can also be curved. Thus, when the flap 42 pivots towards the plate 2, the plates take a curvature corresponding to the fold line and the free edge. The flap is articulated by pivoting until its free edge comes to bear on the plate 2 and its small locking tongue 422 is housed inside the window 22 formed in the plate 2. This is shown in FIG. figure 4 . The flap then extends substantially perpendicular to both the plate 71 and the plate 2. Due to the engagement of the tongue 422 in the window 22, the flap is locked in position. The flap can for example be made rigidly. It thus constitutes spacer means that keep the two plates apart from each other.

Etant donné que la poche 3 est fixée à la plaque 1 en 311 et la plaque 2 en 312, l'écartement des deux plaques du fait de l'interposition du rabat d'entretoise a pour effet également d'écarter les parois de la poche. Le volume interne du réservoir augmente ainsi par entrée d'air à travers l'orifice de distribution 321, et avantageusement à travers la pièce de matière poreuse. Bien entendu, ceci n'est possible qu'après retrait de l'organe d'obturation amovible 34. En effet, il n'est pratiquement pas possible, sauf à détruire le distributeur, de rabattre le rabat pour le positionner tel que représenté sur la figure 4 sans avoir préalablement retiré l'organe d'obturation. L'écartement des plaques n'est possible que si de l'air peut pénétrer à l'intérieur du réservoir. Selon l'invention, les plaques sont réalisées en un matériau élastiquement déformable qui leur confère cette caractéristique d'élasticité de rappel. Ainsi, une fois le distributeur dans la configuration représentée sur la figure 4, on peut l'actionner en appuyant sur la plaque à l'aide d'un doigt et en maintenant l'autre plaque à l'aide d'un autre doigt. Dans cette forme de réalisation, les plaques forment chacune des moyens de ressort de rappel. On peut toutefois imaginer une forme de réalisation dans laquelle seulement une seule des plaques forme des moyens de rappel élastique, alors que l'autre plaque peut être parfaitement rigide et servir de surface de réaction. On peut également imaginer que seul le rabat est élastiquement déformable et les plaques rigides. Le rabat souple et une plaque déformable est aussi envisageables.Since the pocket 3 is fixed to the plate 1 at 311 and the plate 2 at 312, the spacing of the two plates due to the interposition of the spacer flap also has the effect of spreading the walls of the pocket. . The internal volume of the reservoir thus increases by air inlet through the dispensing orifice 321, and advantageously through the piece of porous material. Of course, this is possible only after removal of the removable closure member 34. Indeed, it is virtually not possible, except to destroy the dispenser, to fold the flap to position it as shown on the figure 4 without having previously removed the shutter member. Plate spacing is only possible if air can enter the tank. According to the invention, the plates are made of an elastically deformable material which gives them this characteristic of elasticity of return. So, once the distributor in the configuration shown on the figure 4 it can be operated by pressing the plate with one finger and holding the other plate with another finger. In this embodiment, the plates each form spring return means. However, one embodiment can be envisaged in which only one of the plates forms elastic return means, while the other plate can be perfectly rigid and serve as a reaction surface. We can also imagine that only the flap is elastically deformable and rigid plates. The flexible flap and a deformable plate is also conceivable.

On peut rapprocher les plaques l'une de l'autre en déformant la poche. Ceci a pour effet de mettre le réservoir 30 sous pression et ainsi de refouler un mélange d'air de produit fluide à travers l'orifice de distribution.The plates can be brought closer to one another by deforming the pocket. This has the effect of pressurizing the reservoir 30 and thus discharging a mixture of air of fluid product through the dispensing orifice.

On peut ainsi remarquer que le rabat d'entretoise 42 forme des moyens d'armement permettant d'amener les plaques dans une configuration espacée.It can thus be noted that the spacer flap 42 forms arming means for bringing the plates into a spaced configuration.

Les moyens de ressort et d'armement se présentent ici sous la forme d'une enveloppe qui entoure la poche souple 3. On peut également imaginer des formes de réalisation dans lesquelles les moyens de ressort et d'armement se présentent sous la forme de deux bandes ou lames étroites dont une comprend un rabat d'entretoise d'armement. La poche souple 3 serait alors disposée entre ces deux bandes.The spring and arming means are here in the form of an envelope which surrounds the flexible bag 3. It is also possible to imagine embodiments in which the spring and arming means are in the form of two narrow strips or blades, one of which includes an arming spacer flap. The flexible bag 3 would then be disposed between these two bands.

Selon l'invention, le distributeur de produit fluide est pourvu de moyens de commande qui sont désignés dans leurs ensembles par la référence numérique 4 sur la figure 1. Ces moyens d'actionnement peuvent inclure dans leurs définitions le rabat 42 ainsi que le talon de fixation 41, étant donné qu'ils peuvent être réalisés de manière monobloc avec le restant des moyens d'actionnement 4. Les moyens d'actionnement 4 comprennent un organe de traction qui s'étend entre le rabat 42 et l'échancrure 21. L'organe de traction est relié, avantageusement de manière monobloc au bord du rabat 42 où est formé la languette de blocage 422. D'autre part, l'organe de traction comprend une extrémité de traction 442 initialement positionnée dans l'échancrure 21. En tirant sur l'extrémité de traction 442, l'organe de traction transmet la force de traction au rabat 42 qui alors sollicité en pivotement depuis sa position inopérante représentée sur la figure 3 jusqu'à sa position armée représentée sur la figure 4. La position finale est celle où la languette de blocage 442 vient se loger dans la fente 22 de la plaque 2. L'utilisateur va immédiatement comprendre qu'il faut saisir l'extrémité de traction 442 et tirer dessus.According to the invention, the fluid dispenser is provided with control means which are designated in their assemblies by the reference numeral 4 on the figure 1 . These actuating means may include in their definitions the flap 42 as well as the fixing heel 41, since they can be made in one piece with the rest of the actuating means 4. The actuating means 4 comprise a traction member which extends between the flap 42 and the indentation 21. The traction member is connected, advantageously in one piece to the edge of the flap 42 which is formed the locking tab 422. On the other hand, the traction member comprises a pulling end 442 initially positioned in the notch 21. Pulling on the pulling end 442, the traction member transmits the pulling force to the flap 42 which is then pivotally biased from its inoperative position shown on the figure 3 up to his armed position represented on the figure 4 . The final position is that where the locking tongue 442 is housed in the slot 22 of the plate 2. The user will immediately understand that it is necessary to grasp the pull end 442 and pull on it.

L'organe de traction s'étend entre les deux plaques 1 et 2.The traction member extends between the two plates 1 and 2.

De préférence, l'organe d'obturation amovible 34 est solidaire de l'organe de traction, de sorte qu'en tirant sur l'extrémité de traction 442, on effectue simultanément l'armement du distributeur et le retrait de l'organe d'obturation amovible pour dégager l'orifice de distribution 321.Preferably, the removable closure member 34 is integral with the traction member, so that pulling on the pulling end 442, is carried out simultaneously the arming of the dispenser and the removal of the body member. removable shutter to disengage the dispensing orifice 321.

Il s'agit là du concept général réalisé par les moyens d'actionnement de l'invention.This is the general concept realized by the actuating means of the invention.

Les figures destinées à illustrer la présente invention donne cependant un mode de réalisation très pratique de ces moyens d'actionnement 4. Plus particulièrement en référence à la figure 1, on peut voir que les moyens d'actionnement 4 comprennent un étrier de transmission de force 43 ainsi qu'une patte de traction 44. L'étrier et la patte peuvent être réalisés de manière monobloc, ou en variante, la patte 44 peut être fixée, par exemple par collage, sur l'étrier 43. L'étrier 43 comprend deux branches latérales sensiblement parallèle 432 reliées au niveau d'une de leurs extrémités à une âme commune 431. Les branches 432 s'étendent sensiblement parallèlement aux volets 11 de la plaque 1. L'âme 431 est située à proximité de l'échancrure 21. Les branches 432 définissent des extrémités de liaison 433 reliées au rabat 42 de part et d'autre de la languette de blocage 422. L'étrier 43 et le rabat 42 peuvent être réalisés de manière monobloc, avantageusement avec le talon de fixation 41. La patte de traction 44 est reliée à l'étrier 43 au niveau de l'âme commune 431. La patte comprend une extrémité libre de traction 442 positionnée dans l'échancrure 21 et une souche de fixation 441 reliée de manière détachable à l'âme 431. L'organe d'obturation amovible 34 comprend avantageusement une partie d'obturation 431 positionnée de manière étanche sur l'orifice de distribution 321 et une partie d'accrochage 342 fixée à la patte 44. Ceci est clairement visible sur la figure 2. Initialement, avant la première utilisation, le rabat 42 est plaqué sur la plaque 1. L'extrémité de traction 442 est alors positionnée dans l'échancrure 21 sans en faire saillie à l'extérieur. L'utilisateur peut se saisir de l'extrémité de traction 442 et tirer dessus de manière à faire pivoter le rabat 42 et à détacher la partie d'obturation 341 de l'orifice de distribution. En continuant à tirer, l'utilisateur va détacher la patte 44 de l'étrier 43. Ceci est visible sur la figure 5. L'organe d'obturation amovible 34 peut rester fixé à la patte 44, comme on peut le voir sur la figure 5.The figures intended to illustrate the present invention, however, give a very practical embodiment of these actuating means 4. More particularly with reference to FIG. figure 1 it can be seen that the actuating means 4 comprise a force transmission stirrup 43 and a pull tab 44. The stirrup and the tab can be made integrally, or alternatively, the tab 44 can be fixed, for example by gluing, on the stirrup 43. The stirrup 43 comprises two substantially parallel lateral branches 432 connected at one of their ends to a common core 431. The branches 432 extend substantially parallel to the shutters 11 of plate 1. The core 431 is located near the notch 21. The branches 432 define connecting ends 433 connected to the flap 42 on either side of the locking tongue 422. The stirrup 43 and the flap 42 can be made in one piece, advantageously with the attachment heel 41. The pull tab 44 is connected to the yoke 43 at the common core 431. The tab comprises a free traction end 442 positioned in the notch 21 and a fastening strain 441 detachably connected to the core 431. The removable closure member 34 advantageously comprises a sealing portion 431 sealingly positioned on the dispensing orifice 321 and a portion of attachment 342 attached to the leg 44. This is clearly visible on the figure 2 . Initially, before the first use, the flap 42 is pressed onto the plate 1. The pulling end 442 is then positioned in the notch 21 without protruding outside. The user can grab the pull end 442 and pull it so as to pivot the flap 42 and detach the plug portion 341 from the dispensing orifice. Continuing to pull, the user will detach the tab 44 of the stirrup 43. This is visible on the figure 5 . The organ removable closure 34 can remain attached to the tab 44, as can be seen on the figure 5 .

La poche souple 3 est disposée entre l'étrier 43 et la plaque 1, comme on peut le voir sur la figure 1, la poche souple 3 étant représentée en trait pointillé. La forme en étrier permet d'une part une meilleure répartition des forces de traction sur le rabat 42, mais permet également une fixation centrée de la poche 3 au niveau du point 312, représenté sur les figures 3 et 4, qui est situé entre les deux branches. La forme en étrier permet également de réaliser un contact de butée entre l'âme commune 431 et le pli 12 en fin de traction, ce qui a pour conséquence de détacher la patte 44 de l'étrier 43.The flexible bag 3 is disposed between the stirrup 43 and the plate 1, as can be seen on the figure 1 , the flexible pouch 3 being shown in dashed line. The caliper shape allows on the one hand a better distribution of the traction forces on the flap 42, but also allows a centered fixation of the pocket 3 at the point 312, shown in FIGS. Figures 3 and 4 which is located between the two branches. The stirrup shape also makes it possible to make a stop contact between the common core 431 and the fold 12 at the end of traction, which has the consequence of detaching the tab 44 from the stirrup 43.

En variante, on peut également imaginer que l'extrémité de traction soit réalisée par la partie d'accrochage 342 de l'organe d'obturation amovible 34 qui formerait alors une languette de préhension susceptible d'être saisie par l'utilisateur. La forme de réalisation préférée met cependant en oeuvre une pièce monobloc formant l'étrier de transmission 43, le rabat articulé 42 et le talon de fixation 41. Les deux feuilles 1 et 2 sont également réalisées de manière monobloc. La patte de traction 44 est fixée sur l'étrier et l'organe d'obturation amovible 34 est rapporté sur l'orifice de distribution et sur la patte.Alternatively, one can also imagine that the pulling end is formed by the attachment portion 342 of the removable closure member 34 which would then form a gripping tab that can be grasped by the user. The preferred embodiment, however, uses a single piece forming the transmission stirrup 43, the hinged flap 42 and the attachment heel 41. The two sheets 1 and 2 are also made in one piece. The pull tab 44 is fixed on the yoke and the removable closure member 34 is attached to the dispensing orifice and on the tab.

Dans le mode de réalisation représenté sur les figures 6, 7 et 8, l'orifice de distribution 321 débouche latéralement et non plus au sommet de la tête de distribution comme dans le mode de réalisation précédent. C'est principalement la seule différence avec le mode de réalisation précédent : les moyens d'actionnement, et notamment l'organe traction, peuvent être identiques ou quasi-identiques. De ce fait, l'orifice est dirigé vers l'organe de traction et la plaque 2.In the embodiment shown on the Figures 6, 7 and 8 , the dispensing orifice 321 opens laterally and no longer at the top of the dispensing head as in the previous embodiment. This is mainly the only difference with the previous embodiment: the actuating means, and in particular the traction member, may be identical or almost identical. As a result, the orifice is directed towards the traction member and the plate 2.

Plus précisément, lorsque le distributeur est dans son état initial, comme représenté sur la figure 6, la patte de traction 44 est positionnée dans l'échancrure 21 ; l'organe d'obturation amovible 34 masque l'orifice 321 et est relié à le patte 44 et la patte 44 est raccordée à l'âme 431 de l'étrier 43. La patte ou l'âme est située juste devant l'orifice encore obturé. L'âme est percée d'une ouverture 4314 qui est décalée par rapport à l'orifice. La plaque 2 est pourvue d'une fenêtre 24 au niveau de laquelle l'orifice est positionné. On peut ainsi saisir la patte 44 dans l'échancrure 21 et tirer dessus. Ceci a pour effet de déplacer l'étrier : le rabat 42 est soulevé et la partie d'obturation 341 est décollée de l'orifice la partie d'accrochage 342 fixée à la patte. En fin de traction, l'orifice est complètement dégagé et l'ouverture 4314 s'est décalée au niveau de l'orifice de manière sensiblement centrée par rapport à la fenêtre 24 de la plaque 2. En continuant à tirer sur la patte, elle peut éventuellement se désolidariser de l'étrier au point S, de sorte que l'échancrure 21 reste vide. En appuyant sur les plaques pour les rapprocher, du produit fluide est refoulé sous forme pulvérisée à travers l'orifice. Le jet ou spray est diffusé à travers l'ouverture 4314 et la fenêtre 24. L'axe du spray est sensiblement perpendiculaire au plan de la plaque 2.More specifically, when the dispenser is in its initial state, as shown on the figure 6 the pull tab 44 is positioned in the notch 21; the removable closure member 34 masks the orifice 321 and is connected to the tab 44 and the tab 44 is connected to the core 431 of the stirrup 43. The tab or the soul is located just in front of the orifice still closed. The core is pierced with an opening 4314 which is offset with respect to the orifice. The plate 2 is provided with a window 24 at which the orifice is positioned. It is thus possible to grip the tab 44 in the notch 21 and to fire on it. This has the effect of moving the stirrup: the flap 42 is raised and the closing portion 341 is peeled off from the hole attachment portion 342 attached to the tab. At the end of traction, the orifice is completely cleared and the opening 4314 has shifted at the orifice substantially centrally with respect to the window 24 of the plate 2. By continuing to pull on the leg, it may optionally be detached from the stirrup at the point S, so that the indentation 21 remains empty. By pressing on the plates to bring them together, fluid is expelled in powder form through the orifice. The jet or spray is diffused through the opening 4314 and the window 24. The axis of the spray is substantially perpendicular to the plane of the plate 2.

Grâce à cet organe de traction particulier, l'utilisateur peut d'un seul geste intuitif, dégager l'orifice de distribution et amener les moyens de ressort en condition opérante.Thanks to this particular traction member, the user can in a single intuitive gesture, clear the dispensing orifice and bring the spring means in operating condition.
