Description

La présente invention a trait à un ensemble de conditionnement et de distribution, selon le préambule de la revendication 1, équipé d'un embout distributeur tel que pouvant être utilisé pour la distribution de produits, notamment cosmétiques, pharmaceutiques ou dermatologiques. Un tel ensemble peut être utilisé notamment pour la distribution d'un shampoing, d'un gel, d'un produit de maquillage ou de soin, ou d'un lait pour le corps.The present invention relates to a set of packaging and dispensing, according to the preamble of claim 1, equipped with a dispensing tip such as can be used for the distribution of products, including cosmetic, pharmaceutical or dermatological. Such an assembly can be used in particular for the distribution of a shampoo, a gel, a makeup or care product, or a body milk.

On connaît du document GB-795304 un dispositif de distribution d'un produit liquide comportant un embout de distribution muni d'un élément de fermeture retenu élastiquement au niveau d'un orifice de distribution dudit dispositif. Ce dispositif décrit les caractéristiques du préambule de la revendication 1.Document is known GB-795 304 a device for dispensing a liquid product comprising a dispensing nozzle provided with a closure element elastically retained at a dispensing orifice of said device. This device describes the features of the preamble of claim 1.

Dans le domaine de la cosmétique en particulier, un accent est mis sur la recherche de concepts nouveaux, notamment sur des gestuelles nouvelles pour la distribution et/ou l'application du produit.In the field of cosmetics in particular, an emphasis is placed on the search for new concepts, especially on new gestures for the distribution and / or application of the product.

Parmi les critères devant être considérés comme étant des priorités dans le processus de développement d'un nouveau concept de conditionnement et de distribution, figurent, outre la bonne conservation du produit, le caractère pratique, propre, confortable, notamment à l'application, économique à réaliser, et/ou éventuellement ludique.Among the criteria to be considered as priorities in the process of developing a new concept of packaging and distribution, besides the good conservation of the product, is the practicality, cleanliness, comfort, in particular the application, economical to achieve, and / or possibly playful.

De nombreuses solutions ont été proposées, avec plus ou moins de succès sur le marché, pour conditionner et distribuer de tels produits, certaines de ces solutions présentant des inconvénients rédhibitoires, en particulier quant à leur coût ou à leur facilité d'utilisation.Many solutions have been proposed, with varying degrees of success on the market, for packaging and distributing such products, some of these solutions having unacceptable drawbacks, in particular as regards their cost or ease of use.

Aussi, est-ce un des objets de la présente invention que de fournir un ensemble de conditionnement et de distribution permettant la distribution propre et aisée du produit.Also, it is an object of the present invention to provide a packaging and dispensing assembly for the clean and easy distribution of the product.

C'est un autre objet de l'invention que de fournir un ensemble de conditionnement et de distribution équipé de moyens permettant une bonne conservation du produit contenu dans le récipient auquel il est destiné.It is another object of the invention to provide a packaging and dispensing assembly equipped with means for a good preservation of the product contained in the container for which it is intended.

C'est un autre objet encore que de fournir un ensemble de conditionnement et de distribution économique à réaliser, simple à utiliser, et qui permette de faciliter le contrôle de la quantité de produit distribué.It is yet another object to provide a set of packaging and economic distribution to achieve, simple to use, and that facilitates the control of the amount of product distributed.

C'est un autre objet encore de l'invention que de fournir un ensemble de conditionnement et de distribution ayant en outre des caractéristiques originales d'application du produit sur une surface destinée à le recevoir.It is yet another object of the invention to provide a packaging and dispensing assembly further having novel product application characteristics on a surface for receiving it.

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 ensemble pour le conditionnement et la distribution d'un produit selon la revendication 1.According to the invention, these objects are achieved by providing an assembly for packaging and dispensing a product according to claim 1.

Les termes "en appui étanche" désignent au moins une étanchéité au produit. Comme on le verra par la suite, il est possible de prévoir une micro-fuite entre l'élément de fermeture et le siège, de manière à permettre une reprise d'air.The terms "in sealed support" designate at least one seal to the product. As will be seen later, it is possible to provide a micro-leakage between the closure member and the seat, so as to allow a return of air.

Ainsi, l'élément de fermeture participe à une bonne conservation du produit et permet une distribution plus propre du produit. Par ailleurs, le fait que l'ouverture de l'orifice de sortie puisse être contrôlée et commandée par une contrainte mécanique s'exerçant depuis l'extérieur de l'embout, c'est à dire autrement que, depuis l'intérieur de l'embout, sous la poussée du produit, permet de mieux contrôler la distribution de ce dernier, notamment quand il s'agit de le distribuer de façon localisée. De plus, l'utilisateur peut maîtriser le débit avec lequel le produit sort du récipient en exerçant une pression plus ou moins importante sur les parois déformables du récipient. En outre la gestuelle est particulièrement originale.Thus, the closure element contributes to a good preservation of the product and allows a cleaner distribution of the product. Moreover, the fact that the opening of the outlet orifice can be controlled and controlled by a mechanical stress exerted from outside the nozzle, that is to say otherwise than, from the inside of the tip, under the pressure of the product, allows better control of the distribution of the latter, especially when it comes to the distribution of localized way. In addition, the user can control the flow rate with which the product leaves the container by exerting a greater or lesser pressure on the deformable walls of the container. In addition, the gesture is particularly original.

Il est bien évident que l'étanchéité de l'élément de fermeture sur le siège est fonction notamment de la viscosité du produit. Ainsi, les conditions d'obtention d'une telle étanchéité ne seront pas les mêmes pour une composition faiblement visqueuse et pour une composition fortement visqueuse. Cette étanchéité est réglée notamment en ajustant la force de rappel élastique exercée par l'élément de montage.It is obvious that the sealing of the closure element on the seat depends in particular on the viscosity of the product. Thus, the conditions for obtaining such a seal will not be the same for a low viscosity composition and for a highly viscous composition. This seal is adjusted in particular by adjusting the elastic restoring force exerted by the mounting element.

De préférence, lesdits moyens élastiquement déformables sont constitués d'au moins une partie de l'élément de montage. La déformation élastique peut être un allongement élastique, ou un fléchissement, et ce, de tout ou partie de l'élément de montage. Dans le cas d'une portion se déformant par allongement élastique, on réalisera cette portion en matériau élastomérique. Quand il s'agit d'une portion se déformant par flexion, on réalisera cette portion-en utilisant des matériaux thermoplastiques non élastomériques, notamment des polypropylènes, la portion se déformant étant alors configurée de manière à présenter les caractéristiques de flexion élastique requises. Selon un autre mode de réalisation, les moyens élastiques sont constitués d'un moyen auxiliaire, notamment d'un ressort.Preferably, said elastically deformable means consist of at least a part of the mounting element. The elastic deformation may be an elastic elongation or bending of all or part of the mounting member. In the case of a portion deforming by elastic elongation, this portion of elastomeric material will be produced. When it is a portion deforming by bending, this portion will be made using non-elastomeric thermoplastic materials, including polypropylenes, the deforming portion being then configured to have the required elastic bending characteristics. According to another embodiment, the elastic means consist of an auxiliary means, in particular a spring.

Avantageusement, ledit élément de fermeture est conçu de manière à pouvoir s'écarter du siège en réponse au déplacement dudit élément de fermeture en engagement sur une surface apte à recevoir le produit à distribuer, en particulier selon un mouvement sensiblement parallèle à ladite surface. Ainsi, par exemple, en déplaçant l'élément de fermeture en appui sur une surface destinée à recevoir le produit distribué, notamment dans le creux de la main, on oblige l'élément de fermeture à s'écarter de son siège. Dans le cas d'un élément de fermeture formé d'une bille, l'orifice est dégagé en faisant rouler la bille en appui dans le creux de la main, ce qui force la bille à franchir en tout ou partie le bord délimitant le siège dans lequel débouche l'orifice de sortie. Ainsi, l'orifice de sortie est dégagé en tout ou partie, ce qui permet au produit contenu dans le récipient de s'écouler sous l'effet de son poids, et/ou sous l'effet d'une pression pouvant être exercée sur les parois du récipient. La quantité distribuée peut ainsi être contrôlée de manière plus précise. En outre, l'élément de fermeture, en l'occurrence la bille, peut ensuite être utilisé pour masser la surface sur laquelle le produit est à appliquer, de manière à en favoriser la pénétration.Advantageously, said closure element is designed so as to be able to move away from the seat in response to the displacement of said closure element in engagement on a surface adapted to receive the product to be dispensed, in particular in a movement substantially parallel to said surface. Thus, for example, by moving the closure member bearing on a surface for receiving the dispensed product, especially in the palm of the hand, it forces the closure member to move away from its seat. In the case of a closure element formed of a ball, the orifice is released by rolling the ball bearing in the palm of the hand, which forces the ball to cross all or part of the edge defining the seat in which opens the outlet orifice. Thus, the outlet orifice is disengaged in whole or in part, which allows the product contained in the container to flow under the effect of its weight, and / or under the effect of a pressure that can be exerted on the walls of the container. The quantity dispensed can thus be controlled more precisely. In addition, the closure element, in this case the ball, can then be used to massage the surface on which the product is to be applied, so as to promote penetration.

Alternativement, l'élément de fermeture est déplacé de son siège, en utilisant un doigt de la main tenant le récipient sur lequel est monté l'embout, la pressurisation du produit via les parois souples du récipient, étant, le cas échéant, réalisée grâce à l'autre main.Alternatively, the closure member is moved from its seat, using a finger of the hand holding the container on which is mounted the nozzle, the pressurization of the product via the flexible walls of the container, being, if necessary, achieved through to the other hand.

L'élément peut être configuré autrement que sous forme d'une bille. L'essentiel est que sa forme permette, d'une part la fermeture "étanche" de l'orifice de sortie de l'embout, d'autre part qu'une contrainte mécanique puisse s'exercer dessus, depuis l'extérieur de l'embout, et enfin, qu'en réponse à cette contrainte, que l'élément de fermeture puisse se déplacer par rapport au siège de manière à dégager au moins en partie l'orifice.The element can be configured other than as a ball. The essential thing is that its shape allows, on the one hand the "sealed" closure of the outlet orifice of the tip, on the other hand that a mechanical stress can be exerted on it, from outside the and, finally, in response to this constraint, that the closure member can move relative to the seat so as to clear at least part of the orifice.

Alternativement, et outre la possibilité de déplacer l'élément de fermeture depuis l'extérieur de l'embout, il est possible d'en provoquer le déplacement en réponse à une pression exercée à l'intérieur de l'embout par le produit à distribuer. Dans le cas d'un élément de fermeture sous forme d'une bille, le produit s'écoule tout autour de la bille, entre cette dernière et le siège délimité par l'orifice de sortie. Ainsi, l'utilisateur choisit entre les deux modes de distribution.Alternatively, and in addition to the possibility of moving the closure member from outside the nozzle, it is possible to cause displacement in response to a pressure exerted inside the nozzle by the product to be dispensed . In the case of a closure element in the form of a ball, the product flows all around the ball, between the latter and the seat defined by the outlet orifice. Thus, the user chooses between the two modes of distribution.

De préférence, ledit élément de fermeture comprend au moins une portion de surface sphérique, ledit siège étant formé d'un renfoncement dans lequel débouche ledit orifice de sortie. La forme du siège est choisie de sorte que ce dernier, en combinaison avec l'élément de fermeture, fasse étanchéité pour le produit, notamment sur une zone annulaire audit orifice de sortie. Ainsi que mentionné précédemment, ledit élément de fermeture forme avantageusement une sphère complète. La surface délimitée par le siège et sur laquelle va s'appuyer l'élément de fermeture est fonction de l'étanchéité requise, et de la facilité recherchée à l'ouverture. Dans le cas d'un élément de fermeture sous forme d'une bille, il est avantageux de réaliser le siège sous forme d'une calotte hémisphérique aux dimensions correspondantes, l'essentiel étant que la bille puisse être déplacée de son siège en la contraignant depuis l'extérieur. Alternativement, pour un élément de fermeture sous forme d'une bille, le siège est de forme tronconique. Dans la pratique, et réduit à sa plus simple expression, le siège est formé essentiellement d'un bord libre, annulaire, délimitant l'orifice de sortie de l'embout, la section du bord libre étant choisie en fonction du diamètre de l'élément de fermeture de sorte que celui-ci, en l'absence de contrainte, repose de façon stable sur ledit siège.Preferably, said closure element comprises at least one spherical surface portion, said seat being formed of a recess into which said outlet orifice opens. The shape of the seat is chosen so that the latter, in combination with the closure element, seals for the product, in particular on an annular zone to said outlet orifice. As mentioned above, said closure element advantageously forms a complete sphere. The surface defined by the seat and on which will press the closure element is a function of the required sealing, and the desired ease of opening. In the case of a closure element in the form of a ball, it is advantageous to make the seat in the form of a cap hemispherical to the corresponding dimensions, the essential being that the ball can be moved from its seat by forcing it from the outside. Alternatively, for a closure element in the form of a ball, the seat is of frustoconical shape. In practice, and reduced to its simplest expression, the seat is formed essentially of a free edge, annular delimiting the outlet orifice of the nozzle, the section of the free edge being chosen according to the diameter of the closing element so that it, in the absence of stress, rests stably on said seat.

L'élément de montage peut être réalisé, en tout ou partie, en un matériau choisi parmi les élastomères thermoplastiques ou réticulés, notamment les Silicones, les Nitriles, les Latex naturels ou synthétiques, les EPDM, les Polyuréthanes, les mélanges de Polypropylène et de SBS, SEBS, ou EPDM, les Polyéthylènes de très basse densité, les mélanges à base de polyesters glycols (TPU) ou de Polyéther glycols (PEBA et COPE), les Chlorures de polyvinyle souples (PVC). De préférence, un tel matériau a une dureté comprise entre 20 Shore D et 40 Shore D, et de préférence, entre 40 Shore A et 75 Shore A. Son élasticité peut aller de 0,5 à 5 MPa, et de préférence, de 0,8 à 2 MPa (contrainte de traction à 100 % d'allongement). Ces mêmes matériaux peuvent être utilisés également pour la réalisation de l'élément de fermeture.The mounting element may be made, in whole or in part, of a material chosen from thermoplastic or crosslinked elastomers, in particular Silicones, Nitriles, natural or synthetic latices, EPDMs, polyurethanes, polypropylene and polypropylene mixtures. SBS, SEBS, or EPDM, very low density polyethylenes, mixtures based on polyesters glycols (TPU) or polyether glycols (PEBA and COPE), polyvinyl chloride soft (PVC). Preferably, such a material has a hardness of between 20 Shore D and 40 Shore D, and preferably between 40 Shore A and 75 Shore A. Its elasticity can range from 0.5 to 5 MPa, and preferably from , 8 to 2 MPa (tensile stress at 100% elongation). These same materials can be used also for the realization of the closure element.

L'élément de montage peut être obtenu de moulage avec l'élément de fermeture, de matériaux identiques ou différents, compatibles entre eux, c'est à dire, aptes, à la température de moulage, à former entre eux des liaisons chimiques. L'élément de fermeture n'est pas nécessairement réalisé en matériau élastomérique. A titre d'exemple, on peut citer des polyéthylènes ou des polypropylènes.The mounting element can be obtained by molding with the closure element, of identical or different materials, compatible with each other, that is to say, able, at the molding temperature, to form between them chemical bonds. The closure element is not necessarily made of elastomeric material. By way of example, mention may be made of polyethylenes or polypropylenes.

L'élément de montage peut comporter un organe de liaison dont une extrémité peut être rendue solidaire de l'embout distributeur par collage, soudure, ou par des moyens d'accrochage mécanique, notamment encliquetage ou harponnage. D'autres moyens encore peuvent être utilisés. De tels moyens sont largement utilisés dans l'industrie du conditionnement des produits, notamment cosmétiques, et par conséquent, ne nécessitent pas de description détaillée supplémentaire. L'accrochage se fait de préférence à l'intérieur de l'embout, c'est à dire dans un passage disposé entre l'orifice d'entrée et l'orifice de sortie. Les moyens assurant l'accrochage de l'élément de montage sur l'embout peuvent être eux-mêmes configurés de manière à être déformables élastiquement, en particulier par flexion, de sorte qu'ils assurent en tout ou partie, le rappel élastique de l'élément de fermeture sur son siège.The mounting member may comprise a connecting member whose end can be secured to the dispensing tip by gluing, welding, or mechanical attachment means, including snap or harpooning. Still other means can be used. Such means are widely used in the packaging industry of products, especially cosmetics, and therefore do not require additional detailed description. The attachment is preferably inside the mouthpiece, ie in a passage disposed between the inlet port and the outlet port. The means ensuring the attachment of the mounting element on the tip may themselves be configured so as to be elastically deformable, in particular by bending, so that they provide all or part, the elastic return of the closing element on its seat.

De préférence, des moyens sont prévus pour permettre la fixation dudit embout sur le récipient contenant le produit à distribuer. Typiquement, l'embout distributeur peut être vissé, claqué, soudé ou collé sur le récipient. Un capuchon amovible peut être prévu pour, notamment lors du transport, empêcher que l'élément de fermeture ne s'écarte de son siège et provoque une sortie accidentelle de produit. Ainsi, en position fermée, un tel capuchon peut être en appui sur l'élément de fermeture de manière à en empêcher tout déplacement intempestif.Preferably, means are provided to allow attachment of said tip on the container containing the product to be dispensed. Typically, the dispenser tip can be screwed, slammed, welded or glued to the container. A removable cap may be provided for, especially during transport, prevent the closure element from moving away from its seat and causes an accidental release of product. Thus, in the closed position, such a cap may be supported on the closure element so as to prevent inadvertent movement.

L'embout applicateur peut occuper par rapport au récipient, une position dite de "transport" dans laquelle, même dans le cas d'une surpression intempestive à l'intérieur du récipient, le produit ne peut pas sortir. De tels moyens sont bien connus, et fonctionnent par exemple, sur la base d'un ou plusieurs orifices qui peuvent être mis sélectivement en regard les uns des autres.The applicator tip may occupy with respect to the container, a so-called "transport" position in which, even in the case of an inadvertent overpressure inside the container, the product can not go out. Such means are well known, and operate for example on the basis of one or more orifices which can be selectively facing each other.

Un tel ensemble peut être utilisé pour le conditionnement et la distribution d'un produit cosmétique, notamment un produit capillaire, solaire, de soin, ou d'hygiène corporelle.Such an assembly can be used for the packaging and dispensing of a cosmetic product, especially a hair product, solar, care, or personal hygiene.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • la figure 1 illustre un mode de réalisation préférentiel d'un ensemble équipé d'un embout de distribution selon l'invention ;

  • les figures 5 et 6, 7, 8A-8B, et 9 illustrent encore d'autres modes de réalisation de l'embout distributeur selon l'invention, et en particulier, du montage de l'élément de fermeture sur l'embout.
The invention consists, apart from the arrangements described above, in a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • FIG. 1 illustrates a preferred embodiment of an assembly equipped with a dispensing nozzle according to the invention;
  • Figure 2 illustrates a perspective section of the dispensing tip mounted on the assembly shown in Figure 1;
  • Figure 3 schematically illustrates the operation of the dispensing nozzle according to the invention;

  • Figures 5 and 6, 7, 8A-8B, and 9 further illustrate other embodiments of the dispensing nozzle according to the invention, and in particular, mounting the closure member on the tip.

L'ensemble 1 représenté à la figure 1 comprend un récipient 2 dont une extrémité est fermée par un fond 3, et dont l'autre extrémité forme un col 4 se terminant par un bord libre délimitant une ouverture 5. Le col 4 comporte sur sa surface extérieure un filetage 6, apte à coopérer avec un filetage correspondant 7 prévu sur une surface interne d'un embout distributeur 10. Le récipient 2 est obtenu de moulage d'un matériau thermoplastique, tel que du polyéthylène ou du polypropylène. Les parois latérales du récipient 2 sont souples et déformables sous la pression, notamment des mains de l'utilisateur, de manière à permettre de contraindre la sortie du produit via l'embout distributeur 10 qui va maintenant être décrit en détail. Le produit peut être un shampooing, un lait corporel, un produit démaquillant, un lait solaire, etc.The assembly 1 represented in FIG. 1 comprises a receptacle 2, one end of which is closed by a bottom 3, and the other end of which forms a neck 4 terminating in a free edge delimiting an opening 5. The neck 4 comprises on its outer surface a thread 6, adapted to cooperate with a corresponding thread 7 provided on an inner surface of a dispensing nozzle 10. The container 2 is obtained by molding a thermoplastic material, such as polyethylene or polypropylene. The side walls of the container 2 are flexible and deformable under pressure, including the hands of the user, so as to allow to constrain the outlet of the product via the nozzle 10 which will now be described in detail. The product can be a shampoo, a body milk, a makeup remover, a solar milk, etc.

Ainsi qu'il apparaît plus clairement sur la vue en coupe de la figure 2, l'embout distributeur 10 comporte une première portion cylindrique 11, sur la surface interne de laquelle est ménagé le filetage 7. D'autres moyens pourraient être bien sûr envisagés pour assurer la fixation de l'embout 10 sur le récipient 2. A titre d'exemple, on peut mentionner l'encliquetage, le collage, ou la soudure. La portion cylindrique 11 délimite un orifice d'entrée 8 pour le produit à distribuer.As it appears more clearly in the cross-sectional view of FIG. 2, the dispensing nozzle 10 has a first cylindrical portion 11 on the internal surface of which the threading 7 is formed. Other means could of course be envisaged. to ensure the attachment of the tip 10 on the container 2. By way of example, mention may be made of snapping, gluing, or welding. The cylindrical portion 11 defines an inlet port 8 for the product to be dispensed.

La jupe cylindrique 11 se prolonge, sur une partie substantielle de la hauteur de l'embout 10, par une partie tronconique 12, dont la section va en diminuant dans la direction opposée à la partie cylindrique 11. La portion tronconique 12 se termine par un orifice de sortie 13 débouchant dans une partie tronconique inversée 14, de faible hauteur, qui, comme on le verra plus en détail par la suite, forme un siège pour une bille 15, apte à fermer de manière sélective ledit orifice de sortie 13. Tout comme le récipient 2, l'embout distributeur 10 peut être obtenu de moulage d'un matériau thermoplastique du même type que celui utilisé pour la réalisation du récipient 2.The cylindrical skirt 11 extends, over a substantial part of the height of the nozzle 10, by a frustoconical portion 12, whose section decreases in the opposite direction to the cylindrical portion 11. The frustoconical portion 12 ends with a outlet orifice 13 opening into an inverted frustoconical portion 14, of low height, which, as will be seen in more detail later, forms a seat for a ball 15, adapted to selectively close said outlet orifice 13. All Like the container 2, the dispensing nozzle 10 can be obtained by molding a thermoplastic material of the same type as that used for producing the container 2.

Au sommet de l'embout distributeur 10, est disposée une bille 15, solidaire d'un élément de montage 30. L'élément de montage 30 comprend un organe de liaison 16 dont une première extrémité est solidaire de l'élément de fermeture 15. Ledit organe de liaison 16 est réalisé en matériau élastomérique, par exemple en silicone. Une autre extrémité de l'organe de liaison 16 est reliée à une boucle 17 en polypropylène, destinée à être accrochée sur un élément d'accrochage 18, formé de moulage à l'intérieur de la partie tronconique 12. Dans la représentation des figures 1 et 2, la bille 15 repose sur le siège 14, et obture de manière étanche l'orifice de sortie 13 de l'embout distributeur 10. Dans cette position, l'organe de liaison 16 est tendu partiellement de manière à, par rappel élastique, contraindre la bille 15 en appui sur le siège 14. En outre, dans cette position, il peut être prévu une micro fuite entre le siège 14 et l'élément de fermeture 15, de manière à réaliser une reprise d'air lorsque l'élément de fermeture est en position sur son siège. Une telle micro fuite peut être obtenue en conférant au siège 14 et/ou à l'élément de fermeture 15, un état de surface approprié. Alternativement, cette reprise d'air peut se faire uniquement lors de la fermetureAt the top of the dispenser tip 10 is disposed a ball 15 secured to a mounting member 30. The mounting member 30 comprises a connecting member 16 having a first end integral with the closure member 15. Said connecting member 16 is made of elastomeric material, for example silicone. Another end of the connecting member 16 is connected to a loop 17 of polypropylene, intended to be hooked on a fastening element 18, formed by molding inside the frustoconical portion 12. In the representation of FIGS. and 2, the ball 15 rests on the seat 14, and sealingly closes the outlet orifice 13 of the dispensing nozzle 10. In this position, the connecting member 16 is stretched partially so as to, by elastic return forcing the ball 15 to bear on the seat 14. In addition, in this position, a micro leakage can be provided between the seat 14 and the closure element 15, so as to effect a return of air when the closure element is in position on its seat. Such micro leakage can be achieved by providing the seat 14 and / or the closure member 15 with a suitable surface condition. Alternatively, this air intake can be done only when closing

Selon une possibilité de réalisation, l'organe de liaison 16, la bille 15, et la boucle d'accrochage 17 peuvent être obtenus de moulage d'un seul et même matériau élastomérique. Alternativement, la bille 15 et la boucle d'accrochage 17 sont réalisés en un premier matériau non élastomérique tandis que l'organe de liaison 16 est réalisé en élastomère, l'ensemble pouvant être obtenu par bi-injection. Alternativement encore, les différents éléments composant l'élément de montage et l'élément de fermeture peuvent être réalisés séparément, et assemblés par collage, soudure, ou tout autre moyen d'accrochage mécanique.According to one possible embodiment, the connecting member 16, the ball 15, and the catching loop 17 can be obtained by molding a single elastomeric material. Alternatively, the ball 15 and the fastening loop 17 are made of a first non-elastomeric material while the connecting member 16 is made of elastomer, the assembly can be obtained by bi-injection. Alternatively again, the various elements making up the mounting element and the closing element can be made separately, and assembled by bonding, welding, or any other mechanical fastening means.

L'ensemble illustré à la figure 1 comprend également un capuchon amovible 19, apte, en position fermée, à assurer l'immobilisation de la bille 15 sur son siège 14, de manière à éviter la distribution accidentelle de produit lors du transport. A cet effet, sur sa face interne, le capuchon 19 forme un renfoncement 20 de profil correspondant au profil de la bille 15.The assembly illustrated in Figure 1 also comprises a removable cap 19, able, in the closed position, to ensure the immobilization of the ball 15 on its seat 14, so as to avoid the accidental distribution of product during transport. In this indeed, on its internal face, the cap 19 forms a recess 20 of profile corresponding to the profile of the ball 15.

Ainsi que représenté à la figure 3, pour distribuer du produit, l'utilisateur appuie légèrement la bille 15 dans le creux de sa main, et lui imprime un mouvement latéral, selon une direction sensiblement parallèle à la surface de la main. La bille 15, ainsi contrainte en appui dans le creux de la main, se déplace latéralement par rapport au siège 14, ce qui dégage en partie l'orifice 13. Ce déplacement de la bille 15 s'accompagne d'un allongement élastique de l'organe de liaison 16. Dans cette position semi dégagée de l'orifice 13, l'utilisateur exerce une pression sur les parois latérales du corps du récipient, de manière à provoquer la sortie sous pression du produit. Alternativement, dans le cas d'un produit plus liquide, ce dernier s'écoule naturellement sous l'effet de son poids.As shown in Figure 3, to distribute the product, the user slightly presses the ball 15 in the palm of his hand, and prints a lateral movement in a direction substantially parallel to the surface of the hand. The ball 15, thus constrained in support in the hollow of the hand, moves laterally with respect to the seat 14, which partly releases the orifice 13. This movement of the ball 15 is accompanied by an elastic elongation of the ball. In this semi-unobstructed position of the orifice 13, the user exerts pressure on the lateral walls of the container body, so as to cause the product to exit under pressure. Alternatively, in the case of a more liquid product, the latter flows naturally under the effect of its weight.

Lorsque l'utilisateur interrompt l'appui de la bille 15 sur la surface de la main, l'organe de liaison 16 exerce une force apte à rappeler la bille en appui étanche sur le siège 14 de manière à obturer l'orifice 13. Dans cette position fermée, la bille 15 peut être utilisée comme organe de massage de la surface sur laquelle le produit est à appliquer de manière à en favoriser la pénétration.When the user interrupts the support of the ball 15 on the surface of the hand, the connecting member 16 exerts a force able to return the ball in sealing engagement on the seat 14 so as to close the orifice 13. In this closed position, the ball 15 can be used as a massage member of the surface on which the product is to be applied so as to promote penetration.

Il est à noter qu'avec une telle conception, la sortie du produit peut être provoquée également, simplement en exerçant une pression sur les parois souples du récipient. Le produit ainsi pressurisé exerce une pression suffisante pour décoller la bille 15 de son siège 14, et sortir de façon uniforme tout autour de la bille.It should be noted that with such a design, the outlet of the product can be caused also simply by exerting pressure on the flexible walls of the container. The product thus pressurized exerts sufficient pressure to take off the ball 15 from its seat 14, and out evenly around the ball.

Dans les représentations des figures 4A et 4B, l'élément de montage 30 comprend un organe d'accrochage constitué d'un élément en croix, semi rigide 21. L'élément en croix 21 est solidaire d'une extrémité de l'organe de liaison élastique 16. L'autre extrémité de l'organe de liaison 16 est solidaire de la bille 15, réalisée en un matériau identique au matériau formant l'organe d'accrochage. L'ensemble est formé par bi-injection. Pour assembler l'embout distributeur, l'opérateur introduit l'organe en croix 21 dans le passage débouchant sur l'orifice de sortie 13. Ce faisant les branches de l'organe en croix se replient en direction de l'organe de liaison 16, jusqu'à ce qu'elles arrivent dans la zone de plus grande section 22 de l'embout 10. A cet instant, les branches de l'organe 21 reprennent leur position de déploiement maximal, où elles assurent le blocage de l'ensemble à l'intérieur de l'embout 10. Selon ce mode de réalisation, il est à noter que les branches de l'organe en croix 21, en raison de leur aptitude, en position montée, à fléchir (dans une direction opposée à leur direction de fléchissement pendant leur montage) ajoutent à la déformabilité élastique de l'élément de montage 30, dont l'essentiel toutefois, résulte de la déformabilité élastique de l'organe de liaison 16.In the representations of FIGS. 4A and 4B, the mounting element 30 comprises a fastening element consisting of a cross-shaped, semi-rigid element 21. The cross-shaped element 21 is integral with one end of the elastic connection 16. The other end of the connecting member 16 is integral with the ball 15, made of a material identical to the material forming the fastening member. The set is formed by bi-injection. To assemble the dispensing tip, the operator introduces the cross member 21 into the passage opening on the outlet orifice 13. In doing so, the branches of the cross member fold back towards the connecting member 16 , until they arrive in the area of greater section 22 of the tip 10. At this moment, the branches of the member 21 resume their maximum deployment position, where they ensure the locking of the assembly inside the tip 10. According to this embodiment, it is note that the branches of the cross member 21, because of their ability, in mounted position, to bend (in a direction opposite to their direction of deflection during their assembly) add to the elastic deformability of the mounting element 30, the essential part however, results from the elastic deformability of the connecting member 16.

Selon une variante (non représentée) du mode de réalisation précédent, l'élasticité résulte de la présence d'un ressort, disposé entre l'organe 21 et l'organe de liaison 16, réalisé en matériau rigide, ledit ressort s'effaçant lors de l'introduction, par le biais d'une butée.According to a variant (not shown) of the previous embodiment, the elasticity results from the presence of a spring disposed between the member 21 and the connecting member 16, made of rigid material, said spring being erased during of the introduction, through a stop.

Dans le mode de réalisation de la figure 5, le moyen d'accrochage 25 de l'élément de montage 30, est constitué d'un élément semi-rigide, lequel est encliqueté, collé ou soudé à l'intérieur d'un évidement ménagé sur la surface intérieure de l'embout. L'organe de liaison 16, reliant le moyen d'accrochage 25 à l'élément de fermeture 15, est réalisé en élastomère.In the embodiment of FIG. 5, the hooking means 25 of the mounting element 30 consists of a semi-rigid element which is snapped, glued or welded inside a hollow recess. on the inner surface of the mouthpiece. The connecting member 16, connecting the attachment means 25 to the closure element 15, is made of elastomer.

Dans le mode de réalisation de la figure 6, l'accrochage de la bille 15 à l'embout 10 se fait au moyen d'un organe formant harpon 23, qui lors de son insertion dans l'embout 10, est apte à prendre une position d'encombrement réduit jusqu'au moment où il arrive dans une zone de plus grande section. A ce moment, par rappel élastique, le harpon 23 se déploie et assure la solidarisation de l'élément de montage 30 et de l'élément de fermeture 15 par rapport à l'embout distributeur 10. L'organe 23, ainsi que la bille 15, sont réalisés en polypropylène ou en polyéthylène. L'organe de liaison 16 est réalisé en élastomère de nitrile.In the embodiment of Figure 6, the attachment of the ball 15 to the tip 10 is by means of a harpoon member 23, which upon insertion into the tip 10, is adapted to take a reduced clutter position until it arrives in a zone of larger section. At this moment, by elastic return, the harpoon 23 unfolds and secures the mounting member 30 and the closure member 15 relative to the dispenser tip 10. The member 23, and the ball 15, are made of polypropylene or polyethylene. The connecting member 16 is made of nitrile elastomer.

Dans le mode de réalisation de la figure 7, l'élément de fermeture 15 est réalisé en élastomère de silicone, et est formé d'une sphère tronquée, traversée en son centre par un canal 34. L'élément de montage 30 est constitué d'un organe de liaison 16, dont une extrémité est reliée à un élément formant harpon 31 ayant au moins deux pattes espacées angulairement. L'autre extrémité de l'organe de liaison 16 est solidaire d'une portion de sphère 33 de forme telle, qu'en position montée, elle réalise le complément de la portion tronquée de l'élément de fermeture 15. L'organe de liaison 16 comporte une portion 32 de plus grande section, apte à être montée serrante dans le canal 34, de manière à immobiliser l'élément de montage 30 sur l'élément de fermeture 15. L'élément de montage 30 est obtenu de moulage d'une seule pièce, en polypropylèneIn the embodiment of Figure 7, the closure member 15 is made of silicone elastomer, and is formed of a truncated sphere, traversed at its center by a channel 34. The mounting member 30 consists of a connecting member 16, one end of which is connected to a harpoon element 31 having at least two legs spaced angularly. The other end of the connecting member 16 is integral with a sphere portion 33 of such shape that in position mounted, it performs the complement of the truncated portion of the closure member 15. The connecting member 16 comprises a portion 32 of larger section, adapted to be mounted tightly in the channel 34, so as to immobilize the element mounting member 30 on the closure member 15. The mounting member 30 is made of one-piece polypropylene molding.

L'élément de montage 30 est assemblé en premier lieu avec l'élément de fermeture 15. Pour ce faire, les pattes du harpon 31 sont mises en engagement à l'intérieur du canal 34. Les extrémités libres des pattes du harpon 31 se replient en direction de l'organe de liaison 16, jusqu'à franchissement complet du canal 34. Après franchissement complet du canal 34, les pattes reprennent élastiquement leur position de déploiement maximal. Le mouvement de translation de l'élément de montage 30 par rapport à l'élément de fermeture, se poursuit jusqu'à enfoncement complet de la portion serrante 32 à l'intérieur du canal 34. L'ensemble ainsi monté est alors positionné sur l'embout 10. Pour ce faire, les pattes du harpon 31 sont mises en engagement à l'intérieur du passage de sortie de l'embout. Ce faisant, lors du franchissement de la portion de section réduite de l'embout distributeur 10, les pattes du harpon 31 se replient en direction de l'organe de liaison 16. En atteignant la portion de plus large section 22, les pattes du harpon 31 se déploient et assurent l'accrochage irréversible de l'ensemble formé de l'élément de montage 30 et de l'élément de fermeture 15 sur l'embout 10.The mounting member 30 is first assembled with the closure member 15. To do this, the legs of the harpoon 31 are engaged within the channel 34. The free ends of the legs of the harpoon 31 fold back in the direction of the connecting member 16, until complete crossing of the channel 34. After complete crossing of the channel 34, the tabs elastically resume their maximum deployment position. The translational movement of the mounting member 30 relative to the closure member, continues until complete depression of the clamping portion 32 inside the channel 34. The assembly thus mounted is then positioned on the To this end, the legs of the harpoon 31 are engaged within the outlet passage of the mouthpiece. In doing so, when crossing the reduced section portion of the dispenser tip 10, the legs of the harpoon 31 fold back towards the connecting member 16. By reaching the portion of wider section 22, the legs of the harpoon 31 unfold and provide irreversible attachment of the assembly formed of the mounting member 30 and the closure member 15 on the tip 10.

Lors de la distribution du produit, en réponse à une contrainte mécanique exercée sur l'élément de fermeture 15, les pattes du harpon 31 fléchissent élastiquement dans une direction opposée à leur direction de fléchissement lors du montage. L'élément de fermeture 15 se déplace par rapport au siège 14 de manière à permettre la sortie du produit. Lorsque cesse la contrainte, les pattes du harpon génèrent une force apte à rappeler élastiquement l'élément de fermeture en position fermée sur le siège 14.When dispensing the product, in response to a mechanical stress exerted on the closure member 15, the harpoon tabs 31 resiliently bend in a direction opposite to their direction of deflection during assembly. The closure member 15 moves relative to the seat 14 so as to allow the exit of the product. When the stress ceases, the legs of the harpoon generate a force able to resiliently return the closing element in the closed position on the seat 14.

Dans le mode de réalisation des figures 8A et 8B, l'élément de montage 30 et l'élément de fermeture 15 sont obtenus de moulage, d'une seule pièce, réalisée en élastomère thermoplastique. L'élément de montage 30 comprend une portion en U 41 apte à être fixée, notamment par soudage, sur l'extrémité de l'embout 10 délimitant l'orifice de sortie 13. Une jupe interne 42 de la portion en U s'étend sur toute la hauteur d'un passage de plus faible section 43 de l'embout 10. La jupe 42 est solidaire d'une première extrémité d'un organe de liaison 16, reliant la portion en U à l'élément de fermeture 15. Après moulage, l'élément de fermeture 15 est positionné correctement par rapport à l'élément de montage 30, de la manière illustrée par la flèche F de la figure 8B, le passage de la bille 15 à l'intérieur de la jupe 42 étant rendu possible du fait de l'élasticité des matériaux. Lors de la distribution, le fonctionnement est comparable à celui de la figure 5.In the embodiment of Figures 8A and 8B, the mounting member 30 and the closure member 15 are integrally molded, made of thermoplastic elastomer. The mounting element 30 comprises a U-shaped portion 41 capable of being fixed, in particular by welding, to the end of the endpiece 10 delimiting the outlet orifice 13. An inner skirt 42 of the U-shaped portion extends over the entire height of a passage of smaller section 43 of the nozzle 10. The skirt 42 is integral with a first end of a connecting member 16, connecting the U-shaped portion to the closure member 15. After molding, the closure member 15 is positioned correctly with respect to the mounting member 30, as illustrated by the arrow F of Figure 8B, the passage of the ball 15 inside the skirt 42 being made possible due to the elasticity of the materials. When dispensing, the operation is comparable to that of Figure 5.

Le mode de réalisation de la figure 9 se distingue de celui des figures 4A et 4B en ce que l'élément de montage 30 et l'élément de fermeture 15 sont traversés par un passage axial 44, apte à permettre l'insertion d'un outil sous forme d'une aiguille, destinée à faciliter le montage de l'ensemble sur l'embout 10. En outre, selon ce mode de réalisation, l'élément de fermeture 15, et l'élément de montage 30 sont obtenus de moulage d'un polypropylène, la déformabilité élastique résultant essentiellement du fléchissement élastique des pattes de l'organe en croix 21, lorsqu'une contrainte est exercée sur l'élément de fermeture 15.The embodiment of FIG. 9 differs from that of FIGS. 4A and 4B in that the mounting element 30 and the closing element 15 are traversed by an axial passage 44, capable of allowing the insertion of a tool in the form of a needle, intended to facilitate assembly of the assembly on the endpiece 10. In addition, according to this embodiment, the closure element 15, and the mounting element 30 are obtained by molding a polypropylene, the elastic deformability resulting essentially from the elastic deflection of the legs of the cross member 21, when a stress is exerted on the closure element 15.

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'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 can be made without departing from the invention as claimed hereinafter.
