Abstract
Description
La présente invention concerne une tête de distribution et un récipient pressurisé ainsi équipé. The present invention relates to a dispensing head and a pressurized container thus equipped.
Les têtes de distribution actuellement utilisées pour générer des aérosols à usage cosmétique notamment sont réalisées, pour la plupart, dans une matière plastique telle que le polypropylène et comportent généralement un corps fixe assujetti au récipient, ce dernier étant équipé d'une valve, et un poussoir mobile pour actionner la tige de commande de cette valve. The dispensing heads currently used to generate aerosols for cosmetic use in particular are made, for the most part, from a plastic material such as polypropylene and generally comprise a fixed body secured to the container, the latter being equipped with a valve, and a mobile pusher for actuating the control rod of this valve.
Lorsque l'utilisateur enfonce le poussoir, le produit contenu dans le récipient est distribué par une ou plusieurs buses solidaires du poussoir, généralement sous la forme d'un nuage de fines gouttelettes. When the user pushes the pusher, the product contained in the container is distributed by one or more nozzles integral with the pusher, generally in the form of a cloud of fine droplets.
De très nombreux perfectionnements ont été apportés aux têtes de distribution afin d'en simplifier la fabrication et/ou d'améliorer les propriétés de l'aérosol délivré. Cependant, à la connaissance de la société demanderesse, aucun perfectionnement n'a concerné le bruit de fonctionnement de la tête de distribution. Numerous improvements have been made to the dispensing heads in order to simplify their manufacture and / or improve the properties of the aerosol delivered. However, to the knowledge of the applicant company, no improvements have been made to the operating noise of the distribution head.
La présente invention a pour objet de rendre le bruit de fonctionnement de la tête de distribution plus agréable à l'utilisateur. The object of the present invention is to make the operating noise of the dispensing head more pleasant to the user.
Elle y parvient grâce au fait que la tête de distribution est réalisée, au moins partiellement, dans une matière plastique chargée contenant plus de 50 % en poids d'une charge, par rapport au poids total de la matière plastique chargée. It does this by virtue of the fact that the dispensing head is made, at least partially, from a charged plastic containing more than 50% by weight of a charge, relative to the total weight of the charged plastic.
Bien que des matières plastiques chargées aient été proposées dans d'autres secteurs de la technique tels que le secteur automobile, en vue d'améliorer les propriétés vibratoires de certains composants, l'utilisation d'une matière plastique chargée dans le but de modifier le bruit engendré par la génération de l'aérosol n'a encore jamais été proposée. Although charged plastics have been proposed in other technical fields such as the automotive sector, in order to improve the vibratory properties of certain components, the use of a charged plastic in order to modify the noise generated by the aerosol generation has never been proposed.
Grâce à l'invention, le bruit de fonctionnement de la tête de distribution est atténué et/ou les principaux pics du spectre acoustique déplacés vers des fréquences plus agréables à l'oreille. Thanks to the invention, the operating noise of the dispensing head is attenuated and / or the main peaks of the acoustic spectrum displaced towards frequencies more agreeable to the ear.
De préférence, la charge utilisée présente une densité au moins double de celle de la matière plastique avec laquelle elle est mélangée, de préférence une densité au moins triple de celle de la matière plastique utilisée. Preferably, the filler used has a density at least twice that of the plastic material with which it is mixed, preferably a density at least triple that of the plastic material used.
La charge peut être avantageusement choisie parmi les substances minérales présentant une densité supérieure ou égale à 3 g/cm3, telles que par exemple des oxydes métalliques, des sulfures, des hydroxydes, des sulfates ou des phosphates, ou un mélange de ceux-ci. The filler can advantageously be chosen from mineral substances having a density greater than or equal to 3 g / cm 3, such as for example metal oxides, sulphides, hydroxides, sulphates or phosphates, or a mixture of these.
Comme charge utilisable de façon préférentielle, on peut citer par exemple la magnétite, l'hématite et le sulfate de baryum. As filler which can be used preferentially, there may be mentioned, for example, magnetite, hematite and barium sulphate.
Avantageusement, la matière plastique utilisée est le polypropylène et la charge est constituée par de la magnétite dans une proportion d'au moins 60 % par rapport au poids total de la matière plastique chargée. Advantageously, the plastic material used is polypropylene and the filler consists of magnetite in a proportion of at least 60% relative to the total weight of the plastic material loaded.
De préférence, la charge utilisée est conductrice de l'électricité pour réduire les risques d'accumulation d'électricité statique. Preferably, the charge used is electrically conductive to reduce the risk of static electricity accumulation.
L'invention a encore pour objet un récipient pressurisé équipé d'une tête de distribution telle que précitée. The invention also relates to a pressurized container equipped with a dispensing head as mentioned above.
L'invention sera mieux comprise à la lecture de la description détaillée qui suit, d'un exemple de réalisation non limitatif de l'invention, et à l'examen du dessin annexé sur lequel la figure 1 unique représente un récipient pressurisé pourvu d'une tête de distribution conforme à l'invention. The invention will be better understood on reading the following detailed description of a non-limiting exemplary embodiment of the invention, and on examining the attached drawing in which the single FIG. 1 represents a pressurized container provided with a dispensing head according to the invention.
Le dispositif de conditionnement 10 représenté sur la figure 1 est du type bidon aérosol et comporte un récipient pressurisé 11 équipé d'une tête de distribution 12, laquelle comprend un corps 13 fixé sur le récipient 11 et un poussoir 14 mobile par rapport au corps 13. The packaging device 10 shown in FIG. 1 is of the aerosol can type and comprises a pressurized container 11 equipped with a dispensing head 12, which comprises a body 13 fixed on the container 11 and a pusher 14 movable relative to the body 13 .
Le poussoir 14 permet d'actionner la tige de commande de la valve du récipient 11, non représentée sur la figure 1. The pusher 14 actuates the control rod of the valve of the container 11, not shown in FIG. 1.
La tête de distribution 12 comporte une buse de pulvérisation 15 connue en elle-même, à simple orifice ou à canaux tourbillonnaires, permettant de distribuer le produit contenu dans le récipient 11 sous la forme d'un nuage de fines gouttelettes lorsque l'utilisateur appuie sur le poussoir 14. The dispensing head 12 comprises a spray nozzle 15 known in itself, with a single orifice or with swirl channels, making it possible to distribute the product contained in the container 11 in the form of a cloud of fine droplets when the user presses on pusher 14.
La tête de distribution 12 présente la particularité d'être réalisée, au moins partiellement, dans une matière plastique chargée contenant au moins 50 % d'une charge permettant d'atténuer le bruit de fonctionnement et/ou de déplacer les principaux pics du spectre acoustique vers des fréquences plus agréables à l'oreille. The dispensing head 12 has the particularity of being produced, at least partially, in a charged plastic material containing at least 50% of a charge making it possible to attenuate the operating noise and / or to move the main peaks of the acoustic spectrum towards frequencies more pleasant to the ear.
Dans l'exemple décrit, à la fois le corps 13 de la tête de distribution 12, le poussoir 14 et la buse 15 sont réalisés dans un mélange contenant 64 % en poids de magnétite et 36 % en poids de polypropylène. In the example described, both the body 13 of the dispensing head 12, the pusher 14 and the nozzle 15 are made of a mixture containing 64% by weight of magnetite and 36% by weight of polypropylene.
D'autres matières plastiques que le polypropylène pourraient bien entendu être utilisées, par exemple du polyacétal ou du PET, cette liste étant non limitative. Other plastics than polypropylene could of course be used, for example polyacetal or PET, this list being non-limiting.
L'utilisation de magnétite présente des avantages supplémentaires outre le fait de rendre le bruit de fonctionnement de la tête de distribution plus agréable. The use of magnetite has additional advantages in addition to making the operating noise of the dispensing head more pleasant.
La magnétite permet en effet d'éviter d'adjoindre au polypropylène une charge colorante telle que du noir de carbone. Magnetite in fact makes it possible to avoid adding to the polypropylene a coloring charge such as carbon black.
Elle confère en outre un aspect de surface mat, préférable sur le plan esthétique. It also gives a mat surface appearance, preferable from an aesthetic point of view.
Enfin, la magnétite présente des propriétés de conduction électrique permettant de diminuer le risque d'accumulation de charges électriques et favorise l'écoulement desdites charges. Finally, magnetite has electrical conduction properties which make it possible to reduce the risk of accumulation of electrical charges and promotes the flow of said charges.
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit. Of course, the invention is not limited to the embodiment which has just been described.
On peut notamment modifier la forme de la tête de distribution et utiliser une autre charge que de la magnétite.One can in particular modify the shape of the dispensing head and use a different charge than magnetite.
