Abstract

The present invention relates to a system for dispensing a product. The system may include a receptacle containing the product, a tilt-type valve on the receptacle, and a dispensing head for actuating the tilt-type valve and dispensing the product. The dispensing head may include at least one orifice for dispensing the product. The dispensing head and the tilt-type valve may be configured such that actuation of the tilt-type valve may be achieved only by applying a force on the tilt-type valve in a direction lateral to the tilt-type valve.

Description

La présente invention a trait à un ensemble pour le conditionnement et la distribution sous pression d'un produit, notamment cosmétique, tel qu'un produit de soin, un produit d'hygiène corporelle, un produit capillaire, un produit de maquillage ou un produit de protection contre les effets du soleil. Un tel produit peut être notamment sous forme d'un spray, d'une mousse, d'un gel ou d'une crème.The present invention relates to an assembly for the packaging and dispensing under pressure of a product, in particular a cosmetic product, such as a care product, a personal care product, a hair product, a make-up product or a product. protection against the effects of the sun. Such a product may especially be in the form of a spray, a mousse, a gel or a cream.

Dans le domaine du conditionnement aérosol, il existe principalement deux types de valve : l'une, dite à enfoncement, et dont l'actionnement résulte exclusivement d'un appui exercé sur une surface d'appui, dans l'axe de la valve ; l'autre, dite à basculement, connue aussi sous le nom de valve "tilt", et dont l'actionnement peut être provoqué en réponse à une force exercée latéralement ou transversalement à l'axe de la valve. Pour ce dernier type de valve, l'actionnement peut également être provoqué en réponse à une pression exercée axialement. Le choix de telle ou telle valve dépend en particulier de l'endroit où le produit doit être appliqué. Une valve de type à basculement est décrite notamment dans la demande PCT WO 95/03234.In the field of aerosol packaging, there are mainly two types of valve: one, said depression, and whose actuation results exclusively from a pressure exerted on a bearing surface, in the axis of the valve; the other, said tilt, also known as valve "tilt", and whose actuation can be caused in response to a force exerted laterally or transversely to the axis of the valve. For the latter type of valve, the actuation can also be caused in response to an axially exerted pressure. The choice of particular valve depends in particular on the place where the product is to be applied. A type of failover valve is described in particular in PCT application WO 95/03234.

Un des avantages des valves de type à basculement tient au fait que, en raison de leur configuration, l'actionnement peut se faire à la fois en réponse à une pression latérale et à une pression axiale. Cette caractéristique facilite l'utilisation d'un tel dispositif dans toutes les positions d'actionnement.One of the advantages of tilt type valves is that due to their configuration, actuation can be done both in response to lateral pressure and axial pressure. This feature facilitates the use of such a device in all actuating positions.

Toutefois, ce qui, dans certains cas constitue un avantage, peut, pour certaines applications, se révéler être un inconvénient. En effet, il existe certaines applications pour lesquelles, en raison de la forte tendance du produit à se colmater ou à s'oxyder au contact de l'air, il est souhaitable d'obturer de manière aussi étanche que possible l'orifice de distribution du produit. A cet effet, il est souhaitable d'utiliser un capuchon dont la surface intérieure comprend un organe, notamment un picot, qui, en position montée du capot, est en appui étanche contre les bords délimitant l'orifice de distribution. Le risque inhérent à cette configuration, est que, lors de la mise en place du capuchon, celui-ci provoque un actionnement accidentel de la valve par enfoncement axial, et une sortie intempestive de produit. Ce dernier vient ensuite souiller la tête de distribution, ce qui rend peu agréable toute utilisation ultérieure du dispositif.However, which in some cases is an advantage may, for some applications, prove to be a disadvantage. Indeed, there are certain applications for which, because of the strong tendency of the product to clog or oxidize in contact with air, it is desirable to seal as tightly as possible the dispensing orifice of the product. For this purpose, it is desirable to use a cap whose inner surface comprises a member, in particular a pin, which, in the mounted position of the cap, bears tightly against the edges delimiting the dispensing orifice. The risk inherent in this configuration is that, when the cap is put in place, it causes a accidental actuation of the valve by axial depression, and untimely release of product. The latter then comes to defile the dispensing head, which makes any subsequent use of the device unpleasant.

Dans la demande de brevet PCT mentionnée ci-avant, le risque d'actionnement accidentel est réduit (quoi que pas totalement supprimé) en disposant l'extrémité de la tige de valve, en retrait par rapport à un bord supérieur de la tête de distribution. Toutefois, le problème n'est pas résolu du tout quand le produit est du type de ceux mentionnés précédemment, c'est à dire nécessitant une fermeture très étanche de l'orifice de sortie. En effet, un capuchon équipé d'un ergot apte à venir en engagement avec l'orifice de sortie de la tige de valve, peut provoquer un actionnement accidentel de la tige de valve par enfoncement axial. En outre, un tel dispositif n'est pas approprié pour la distribution sous forme d'une crème, d'une mousse, ou d'un gel, dans la mesure où il est difficile de prélever avec la main le produit à sa sortie de la tige de valve.In the PCT patent application mentioned above, the risk of accidental actuation is reduced (although not completely eliminated) by arranging the end of the valve stem, set back with respect to an upper edge of the dispensing head. . However, the problem is not solved at all when the product is of the type mentioned above, ie requiring a very tight closure of the outlet orifice. Indeed, a cap equipped with a lug adapted to come into engagement with the outlet port of the valve stem, may cause an accidental actuation of the valve stem by axial depression. In addition, such a device is not suitable for dispensing in the form of a cream, a mousse, or a gel, since it is difficult to take the product by hand when it leaves the the valve stem.

La même problématique se pose dans le dispositif décrit dans le document US-A-3 583 607. En effet, selon ce document, l'orifice de distribution débouche latéralement et est solidaire d'une pièce emmanchée sur la tige de valve. La pièce délimite une zone d'actionnement, sous forme d'une languette, apte à provoquer une sortie de produit, en réponse à une pression exercée à la fois latéralement et axialement.The same problem arises in the device described in the document US-A-3 583 607. In fact, according to this document, the dispensing orifice opens laterally and is integral with a piece fitted on the valve stem. The part defines an actuating zone, in the form of a tongue, capable of causing a product outlet, in response to a pressure exerted both laterally and axially.

Aussi, est-ce un des objets de l'invention que de réaliser un dispositif résolvant en tout ou partie les problèmes discutés ci-avant en référence aux dispositifs conventionnels.Also, is it an object of the invention to provide a device resolving all or part of the problems discussed above with reference to conventional devices.

C'est en particulier un objet de l'invention que de fournir un dispositif de type aérosol, utilisant une valve "tilt", et dont le risque d'actionnement accidentel, en particulier lors de la mise en place du capuchon de protection, soit réduit de manière sensible.It is in particular an object of the invention to provide an aerosol type device, using a "tilt" valve, and whose risk of accidental actuation, particularly during the installation of the protective cap, is reduced significantly.

C'est un autre objet de la présente invention que de fournir un tel dispositif qui soit à la fois économique à réaliser, fiable, et simple à utiliser.It is another object of the present invention to provide such a device that is both economical to produce, reliable, and simple to use.

C'est un autre objet de l'invention que de fournir un dispositif utilisant une valve tilt, et qui puisse être utilisé également pour des produits sous forme d'une crème, d'un gel, ou d'une mousse.It is another object of the invention to provide a device using a tilt valve, and which can also be used for products in the form of a cream, a gel, or a foam.

C'est un autre objet de l'invention que de fournir un tel dispositif, qui puisse être utilisé également avec des produits risquant de s'altérer au contact de l'air.It is another object of the invention to provide such a device, which can also be used with products liable to deteriorate in contact with air.

D'autres objets encore apparaîtront dans la description détaillée qui suit.Still other objects will appear in the following detailed description.

Selon l'invention, ces objets sont atteints en réalisant un dispositif selon la revendication 1.According to the invention, these objects are achieved by producing a device according to claim 1.

Une pression exercée latéralement à ladite valve s'entend d'une pression exercée selon une direction non parallèle à l'axe de la valve ou de la tige de valve équipant une telle valve, et de préférence, selon une direction sensiblement perpendiculaire à l'axe de la valve ou de la tige de valve. Ainsi, à l'inverse des dispositifs conventionnels équipés d'une valve à basculement dont l'ouverture peut être provoquée à la fois par enfoncement axial et par basculement latéral, l'ouverture de la valve équipant le dispositif selon la présente invention ne peut se faire que par basculement.A pressure exerted laterally to said valve means a pressure exerted in a direction not parallel to the axis of the valve or valve stem equipping such a valve, and preferably in a direction substantially perpendicular to the axis of the valve or valve stem. Thus, unlike conventional devices equipped with a tilt valve whose opening can be caused by both axial depression and lateral tilting, the opening of the valve equipping the device according to the present invention can not be achieved. do that by failover.

En d'autres termes, selon l'invention, la configuration de la tête de distribution est choisie de sorte que l'actionnement de la valve par enfoncement axial ne puisse se produire. Seule une force exercée transversalement à la tige de valve peut provoquer l'ouverture de la valve.In other words, according to the invention, the configuration of the dispensing head is chosen so that actuation of the valve by axial depression can not occur. Only a force exerted transversely to the valve stem can cause the valve to open.

Ainsi, dans le cas où le dispositif utilise un capuchon dont une partie est destinée à venir en engagement étanche avec l'orifice de distribution, les risques de provoquer un actionnement accidentel de la valve, lors de la mise en place du capuchon, sont réduits de manière importante.Thus, in the case where the device uses a cap part of which is intended to come into sealed engagement with the dispensing orifice, the risks of causing an accidental actuation of the valve, when the cap is put in place, are reduced. importantly.

De même, lorsque le produit, notamment sous forme d'un gel, d'une mousse ou d'une crème, est à prélever directement avec le doigt ou la main, directement sur l'orifice de distribution, les risques de provoquer un actionnement non désiré de la valve lors du prélèvement, sont également réduits de manière sensible.Similarly, when the product, especially in the form of a gel, a mousse or a cream, is to be taken directly with the finger or the hand, directly on the dispensing orifice, the risks of causing actuation unwanted valve during sampling, are also reduced significantly.

En outre, une telle configuration autorise une esthétique originale pour ce type de dispositif.In addition, such a configuration allows an original aesthetic for this type of device.

Avantageusement, la tête de distribution comporte des moyens pour en assurer la fixation sur le récipient, l'orifice de distribution débouchant dans une portion de la tête, immobile axialement par rapport au récipient. A titres d'exemples, une telle fixation peut être assurée par encliquetage, collage ou vissage.Advantageously, the dispensing head comprises means for fixing it on the container, the dispensing orifice opening into a portion of the head axially immovable relative to the container. As examples, such a fixing can be provided by snapping, gluing or screwing.

Lorsque le récipient est d'axe X, ledit orifice de distribution, également dénommé orifice de sortie, peut être disposé dans l'axe X du récipient, ou en dehors dudit axe. Dans ce dernier cas de figure, l'orifice de distribution peut être orienté selon une direction inclinée par rapport à l'axe X. Le choix de telle ou telle configuration dépend dans une large mesure du produit à appliquer et de la surface sur laquelle le produit doit être appliqué.When the container is X-axis, said dispensing orifice, also called outlet orifice, may be disposed in the axis X of the container, or outside said axis. In the latter case, the dispensing orifice may be oriented in a direction inclined relative to the axis X. The choice of this or that configuration depends to a large extent on the product to be applied and the surface on which the product must be applied.

De manière préférentielle, la tête de distribution comporte au moins une surface d'appui pour l'actionnement de la valve, ladite (ou lesdites) surface(s) étant apte(s) à fléchir autour d'une zone de la tête de distribution située au voisinage de l'orifice de distribution. Dans l'hypothèse d'une tête de distribution à deux ou plusieurs surfaces d'appui latérales, elles sont de préférence réparties de manière équidistante sur la périphérie de la tête de distribution. De telles surfaces d'appui peuvent être délimitées, au moins en partie, par une découpe formée, notamment de moulage, dans la tête de distribution. Dans ce mode de réalisation, la surface d'appui peut être moulée d'emblée dans la position correspondant à la position de fonctionnement. De préférence, la tête de distribution est constituée d'une seule et même pièce.Preferably, the dispensing head comprises at least one bearing surface for actuating the valve, said (or said) surface (s) being capable (s) to bend around an area of the dispensing head located in the vicinity of the dispensing orifice. In the case of a dispensing head with two or more lateral bearing surfaces, they are preferably distributed equidistantly on the periphery of the dispensing head. Such bearing surfaces may be delimited, at least in part, by a cutout formed, in particular molding, in the dispensing head. In this embodiment, the bearing surface can be molded immediately in the position corresponding to the position of operation. Preferably, the dispensing head consists of a single piece.

Dans ce dernier cas, la (ou les) surface(s) d'appui peut (peuvent) être solidaire(s) via un élément de couplage, d'une portion de la tête de distribution dans laquelle est ménagée un canal débouchant sur l'orifice de distribution, ladite portion étant apte à venir en engagement, notamment par emmanchement à force, avec une tige de valve.In the latter case, the (or) surface (s) bearing can (may) be secured (s) via a coupling element, a portion of the dispensing head in which is formed a channel opening on the dispensing orifice, said portion being adapted to engage, in particular by press fitting, with a valve stem.

Alternativement, ladite (ou lesdites) surface(s) sont apte(s) à fléchir autour d'une zone de la tête de distribution située à l'opposé de l'orifice de distribution. Pour des raisons de démoulage, il peut être souhaitable de mouler la surface d'appui dans une position autre que celle correspondant à la position de fonctionnement, le passage d'une position à l'autre se faisant notamment par pivot autour d'un axe (charnière film, par exemple) perpendiculaire à l'axe de la valve.Alternatively, said (or said) surface (s) are capable (s) to bend around an area of the dispensing head located opposite the dispensing orifice. For reasons of demolding, it may be desirable to mold the bearing surface in a position other than that corresponding to the operating position, the passage from one position to the other being done in particular by pivot about an axis (film hinge, for example) perpendicular to the axis of the valve.

Dans ce dernier cas, la (ou les) surface(s) d'appui peut (peuvent) être apte(s) à passer, notamment par pivot autour d'un axe, d'une première position, dite de moulage, dans laquelle un élément de couplage est à distance d'une portion de la tête de distribution dans laquelle est ménagée un canal débouchant sur l'orifice de distribution, à une seconde position, dite de fonctionnement, dans laquelle ledit élément de couplage est apte, en réponse à une pression exercée latéralement à ladite valve sur une surface d'appui, à venir en engagement avec ladite portion de tête de distribution, et à provoquer l'actionnement de la valve.In the latter case, the (or) surface (s) of support can (may) be adapted (s) to pass, in particular by pivot about an axis, a first position, called molding, in which a coupling element is remote from a portion of the dispensing head in which is formed a channel opening on the dispensing orifice, to a second position, said operating, wherein said coupling element is able, in response at a pressure exerted laterally to said valve on a bearing surface, to come into engagement with said dispensing head portion, and to cause the actuation of the valve.

Avantageusement, le dispositif comprend un capuchon, pour coiffer de manière amovible ladite tête de distribution. Un tel bouchon peut être monté de manière amovible sur le dispositif, notamment par vissage, encliquetage, ou montage serrant.Advantageously, the device comprises a cap, for removably covering said dispensing head. Such a plug can be removably mounted on the device, in particular by screwing, latching or tightening assembly.

De préférence, un tel bouchon comprend un organe, notamment un ergot, un bossage, une jupe, ou un picot, apte à s'appliquer de manière étanche contre l'orifice de distribution du dispositif. Cet organe peut être réalisé en un matériau identique au matériau formant le bouchon, ou en un matériau différent. Dans ce dernier cas, le bouchon peut être obtenu par bi-injection, l'organe d'étanchéité étant formé d'un matériau élastomérique tandis que le reste du bouchon est formé d'un matériau rigide ou semi rigide (PP ou PE).Preferably, such a cap comprises a member, in particular a lug, a boss, a skirt, or a pin, adapted to be sealingly applied against the dispensing orifice of the device. This member may be made of a material identical to the material forming the plug, or a different material. In this last case, the plug can be obtained by bi-injection, the sealing member being formed of an elastomeric material while the remainder of the plug is formed of a rigid or semi-rigid material (PP or PE).

Le dispositif 1 représenté, en vue d'ensemble à la figure 1A, comprend un récipient 2 de forme cylindrique, notamment en aluminium ou en fer blanc. Le récipient est surmonté d'une tête de distribution 10 pour l'actionnement d'une valve "tilt" équipant le récipient 2, et pour la distribution du produit via un orifice de sortie 11, situé dans l'axe X du dispositif. L'actionnement de la valve se fait via une surface d'appui 12 disposée latéralement sur tête de distribution, et conformée sous forme d'une languette apte à fléchir autour d'une zone formée au voisinage de l'orifice de distribution 11. La languette 12 est délimitée en partie par une ouverture 18, sensiblement en forme de U, ménagée dans la paroi latérale de la tête de distribution 10.The device 1 shown in an overall view in FIG. 1A comprises a container 2 of cylindrical shape, in particular of aluminum or tinplate. The container is surmounted by a dispensing head 10 for actuating a valve "tilt" equipping the container 2, and for dispensing the product via an outlet orifice 11, located in the X axis of the device. The actuation of the valve is via a bearing surface 12 disposed laterally on the dispensing head, and shaped as a tongue adapted to bend around an area formed in the vicinity of the dispensing orifice 11. tongue 12 is delimited in part by an aperture 18, substantially U-shaped, formed in the side wall of the dispensing head 10.

Le dispositif 1 comprend un capuchon amovible 6, destiné à être monté légèrement serrant sur la tête de distribution 10, de manière à la protéger de l'environnement extérieur lorsque le dispositif est en position de stockage. Dans le fond du capuchon 6, est formé un bossage axial 7, apte, en position fermée du bouchon, à s'appliquer de manière étanche contre l'orifice de sortie 11.The device 1 comprises a removable cap 6, intended to be mounted slightly tightening on the dispensing head 10, so as to protect it from the external environment when the device is in the storage position. In the bottom of the cap 6 is formed an axial boss 7 adapted, in the closed position of the cap, to be sealingly applied against the outlet orifice 11.

La tête de distribution 10 ainsi que le capuchon 6 peuvent être obtenus de moulage de matériaux thermoplastiques tels que des polyéthylènes ou des polypropylènes. Le produit conditionné dans le dispositif peut être une mousse ou un gel de coiffage, ou une crème de soin. A l'intérieur du récipient 2, le produit peut être pressurisé au moyen d'un gaz propulseur, notamment sous forme comprimée ou liquéfiée. Le produit peut être isolé du moyen propulseur via un piston ou une poche souple.The dispensing head 10 and the cap 6 can be obtained by molding thermoplastic materials such as polyethylenes or polypropylenes. The product packaged in the device may be a styling mousse or gel, or a care cream. Inside the container 2, the product can be pressurized by means of a propellant, especially in compressed or liquefied form. The product can be isolated from the propellant via a piston or a flexible bag.

Les figures 2A-2D auxquelles il est maintenant fait référence illustrent différentes vues en coupe du dispositif représenté de manière plus globale aux figures 1A et 1B.FIGS. 2A-2D, to which reference is now made, illustrate different sectional views of the device shown more generally in FIGS. 1A and 1B.

La tête de distribution 10 est de forme généralement cylindrique, et comprend une première extrémité fermée, configurée sous forme d'un dôme. Au sommet du dôme, dans l'axe X du dispositif, débouche un orifice de sortie 11, formé à une extrémité d'un canal axial 13. L'autre extrémité du canal axial 13 est configurée de manière à pouvoir s'emmancher en serrage sur une tige de valve 3. Le canal 13 s'étend sur environ la moitié de la hauteur axiale de la tête de distribution 10. L'autre extrémité de la tête de distribution est ouverte et comprend sur sa surface intérieure, une pluralité de bourrelets 14, 15, destinés à assurer le montage par encliquetage de la tête de distribution 10 sur le récipient 2. Sur sensiblement toute sa hauteur, le canal axial 13 est solidaire du premier bord d'une portion de couplage 16. L'autre bord de la portion de couplage 16 est solidaire d'une languette 12 formée dans la paroi latérale de la tête de distribution, et apte à fléchir autour d'une zone située sensiblement au sommet du dôme, c'est à dire au voisinage de l'orifice de distribution 11. D'une manière générale, la zone de fléchissement est constituée de la zone au niveau de laquelle la languette 12 se raccorde au reste de la tête de distribution. Cette zone est centrée sur un axe sensiblement perpendiculaire à l'axe X du dispositif 1.The dispensing head 10 is of generally cylindrical shape, and comprises a closed first end, configured in the form of a dome. At the top of the dome, in the X axis of the device, opens an outlet orifice 11, formed at one end of an axial channel 13. The other end of the axial channel 13 is configured so that it can be clamped together. 3. The channel 13 extends over approximately half of the axial height of the dispensing head 10. The other end of the dispensing head is open and comprises on its inner surface a plurality of beads. 14, 15, intended to ensure the snap-fitting of the dispensing head 10 on the container 2. Over substantially its entire height, the axial channel 13 is integral with the first edge of a coupling portion 16. The other edge of the coupling portion 16 is integral with a tongue 12 formed in the side wall of the dispensing head, and able to flex around an area substantially at the top of the dome, that is to say in the vicinity of the orifice 11. In a general way ale, the zone of deflection is constituted of the zone at which the tongue 12 is connected to the rest of the dispensing head. This zone is centered on an axis substantially perpendicular to the axis X of the device 1.

En position montée, telle que représentée à la figure 2C, les bourrelets 14, 15, coopèrent par encliquetage avec le bourrelet de sertissage 4 de la valve 5. Un tel montage assure une immobilisation axiale de la tête de distribution 10 sur le récipient 2. De ce fait, l'orifice de distribution 11 est également fixe axialement par rapport au récipient 2.In the mounted position, as shown in FIG. 2C, the beads 14, 15 cooperate by snap-fitting with the crimping bead 4 of the valve 5. Such an assembly ensures axial immobilization of the dispensing head 10 on the Thus, the dispensing orifice 11 is also fixed axially with respect to the container 2.

Pour utiliser le dispositif selon l'invention, l'utilisateur exerce une pression latérale sur la languette 12, de la manière illustrée par la flèche 17 (figure 2D). Cette pression est transmise, via la portion de couplage 16, à la portion axiale de la tête dans laquelle est ménagé le canal 13. Ce faisant, la tige 3, bascule légèrement au point de provoquer l'ouverture de la valve 5, et la sortie du produit au travers de l'orifice de sortie 11. Typiquement, un basculement de la tige de valve 3 d'un angle de quelques degrés suffit pour en provoquer l'ouverture. En revanche, toute pression exercée ailleurs que sur la languette 12, en particulier sur la partie en dôme de la tête de distribution 10, est sans effet sur la valve 5. De ce fait, les risques d'actionnement accidentel de la valve, en particulier lors de la mise en place du capuchon 6, sont réduits de manière sensible.To use the device according to the invention, the user exerts lateral pressure on the tongue 12, as illustrated by the arrow 17 (FIG. 2D). This pressure is transmitted, via the coupling portion 16, to the axial portion of the head in which the channel 13 is formed. In doing so, the rod 3 slightly tilts to the point of causing the valve 5 to open, and the output of the product through the outlet orifice 11. Typically, a tilting of the valve stem 3 by an angle of a few degrees is sufficient to cause the opening. On the other hand, any pressure exerted elsewhere than on the tongue 12, in particular on the dome portion of the dispensing head 10, has no effect on the valve 5. As a result, the risks of accidental actuation of the valve, in particular particular when the introduction of the cap 6, are reduced significantly.

Selon ce mode de réalisation, la tête de distribution 10 est obtenue directement de moulage, la languette 12 étant moulée directement dans la position qu'elle occupe lors du fonctionnement du dispositif 1. La configuration de l'ouverture 18, sensiblement en forme de U, qui délimite en partie la languette 12, est choisie de manière à ce que le démoulage puisse se faire de façon aisée, tout en respectant une esthétique compatible avec le marché auquel le dispositif 1 est destiné.According to this embodiment, the dispensing head 10 is obtained directly from molding, the tongue 12 being molded directly into the position it occupies during the operation of the device 1. The configuration of the opening 18, substantially U-shaped , which partially delimits the tongue 12, is chosen so that the demolding can be done easily, while respecting an aesthetic compatible with the market to which the device 1 is intended.

Le mode de réalisation des figures 3A-3D diffère du mode de réalisation précédent en ce que la languette 12 est articulée autour d'un axe (formé par une charnière film 19) situé au voisinage de l'extrémité ouverte de la tête de distribution 10. Pour des raisons de moulage/démoulage, la languette 12 est moulée dans une configuration différente de la configuration de fonctionnement du dispositif. La configuration de moulage est représentée en pointillés à la figure 3A. Le passage de la configuration de moulage à la configuration de fonctionnement se fait en faisant pivoter la languette d'environ 90° autour de l'axe défini par la charnière film 19. Un verrouillage, notamment par encliquetage, peut être prévu pour verrouiller la languette 12 dans sa position de fonctionnement.The embodiment of FIGS. 3A-3D differs from the previous embodiment in that the tongue 12 is articulated about an axis (formed by a film hinge 19) situated in the vicinity of the open end of the dispensing head 10. For reasons of molding / demolding, the tongue 12 is molded in a configuration different from the operating configuration of the device. The molding configuration is shown in dashed lines in Figure 3A. The transition from the molding configuration to the operating configuration is done by pivoting the tongue about 90 ° about the axis defined by the film hinge 19. A locking, in particular by snapping, can be provided to lock the tongue 12 in its operating position.

Lors de l'actionnement de la valve, résultant d'une pression exercée latéralement à l'axe X (flèche 17, figure 3D) le basculement de la tige de valve 3, et donc l'ouverture de la valve 5, est provoqué par la mise en engagement d'une extrémité libre de la portion de couplage 16, portée par la languette 12, avec la portion axiale de la tête, dans laquelle est ménagé le canal 13. Lors de l'actionnement, la languette 12 bascule autour de l'axe défini par la charnière film 19.When actuating the valve, resulting from a pressure exerted laterally on the X axis (arrow 17, FIG. 3D), the tilting of the valve stem 3, and therefore the opening of the valve 5, is caused by the engagement of a free end of the coupling portion 16, carried by the tongue 12, with the axial portion of the head, in which the channel 13 is formed. On actuation, the tongue 12 switches around. the axis defined by the film hinge 19.

Le fonctionnement du dispositif selon ce mode de réalisation est par ailleurs en touts points similaire à celui du mode de réalisation précédent. Comme pour le mode de réalisation précédent, l'actionnement de la valve 5 par enfoncement axial de la tige de valve 3 est rendu impossible.The operation of the device according to this embodiment is moreover in all respects similar to that of the previous embodiment. As for the previous embodiment, the actuation of the valve 5 by axial depression of the valve stem 3 is made impossible.

Le mode de réalisation illustré aux figures 4A-4D se distingue du mode de réalisation des figures 2A-2D en ce que le canal 13 comprend une partie axiale 130, emmanchée sur la tige de valve 3, et une partie 131, inclinée par rapport à l'axe débouchant sur l'orifice de distribution 11, de sorte que la sortie de produit (figure 4D) se fasse de manière inclinée par rapport à l'axe X.The embodiment illustrated in FIGS. 4A-4D differs from the embodiment of FIGS. 2A-2D in that the channel 13 comprises an axial portion 130, fitted on the valve stem 3, and a portion 131, inclined with respect to the axis opening on the dispensing orifice 11, so that the product outlet (FIG. 4D) is inclined with respect to the axis X.

Comme pour tous les autres modes de réalisation, toute pression exercée en dehors de la languette 12, en particulier dans l'axe du dispositif 1, est sans effet sur la valve 5. A nouveau, l'actionnement de la valve par enfoncement est rendu impossible.As for all the other embodiments, any pressure exerted outside the tongue 12, in particular in the axis of the device 1, has no effect on the valve 5. Again, the actuation of the valve by depression is rendered impossible.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations may be made without departing from the spirit of the invention as claimed hereinafter.
