Description

La présente invention concerne une nouvelle tête de distribution permettant de générer un spray, destinée à équiper un récipient pressurisé ou une pompe.The present invention relates to a new dispensing head allowing to generate a spray, intended to equip a pressurized container or a pump.

On connaít un certain nombre de têtes de distribution comportant deux buses, à canaux tourbillonnaires dans certains cas, à simple orifice dans d'autres.We know a number of distribution heads comprising two nozzles, in some cases, single-ported in others.

La demande GB-A-2 153 444 décrit une tête de distribution comportant deux buses à simple orifice. Les jets émis étant directifs, les particules se fragmentent au point de rencontre. Chaque buse est fixée sur un porte-buse qui se présente sous la forme d'un tube coudé. Une telle tête de distribution est relativement fragile et peu esthétique.GB-A-2 153 444 discloses a dispensing head comprising two single orifice nozzles. The emitted jets being directional, the particles fragment to the point meeting. Each nozzle is attached to a nozzle holder which is in the form of a elbow tube. Such a dispensing head is relatively fragile and unattractive.

On connaít par le brevet européen EP-B-0 755 878 une tête de distribution comportant deux buses à canaux tourbillonnaires. Dans un mode de réalisation, les buses sont reliées par des tubes flexibles au corps de la tête, ce qui lui donne un aspect futuriste mais complique sa fabrication. Dans un autre mode de réalisation, chaque buse est fixée sur un porte-buse qui est encliqueté à une extrémité dans un logement prévu sur le corps de la tête. Un tel assemblage est relativement peu résistant.EP-B-0 755 878 discloses a dispensing head. comprising two swirl channel nozzles. In one embodiment, the nozzles are connected by flexible tubes to the body of the head, giving it a futuristic appearance but complicates its manufacture. In another embodiment, each nozzle is fixed on a nozzle holder that is snapped to one end in a housing provided on the body of the head. Such an assembly is relatively weak.

On connaít encore par la demande FR-A-2 691 383 une tête de distribution dans laquelle les deux buses sont réalisées sous la forme d'une pièce unique. Une telle structure, si elle est plus résistante tout en facilitant les opérations de démoulage, ne permet pas de réaliser aisément une tête de distribution dans laquelle les sprays émis par les buses convergent avec un angle pouvant dépasser 40°, par exemple. Or, un angle élevé permet de casser l'énergie cinétique des jets et de produire un spray plus doux, ce qui est souhaitable pour certaines applications.We still know from application FR-A-2 691 383 a dispensing head in which the two nozzles are made in the form of a single piece. Such a structure, if it is more resistant while facilitating the demolding operations, do not It is not possible to easily produce a dispensing head in which the sprays emitted by the nozzles converge at an angle that may exceed 40 °, for example. An angle high can break the kinetic energy of the jets and produce a softer spray, this which is desirable for some applications.

Il existe par conséquent un besoin pour disposer d'une nouvelle tête de distribution, à la fois robuste et peu coûteuse à fabriquer, dans laquelle l'angle entre les axes des buses puisse être supérieur à 40° si cela est souhaité.There is therefore a need to have a new head of distribution, both robust and inexpensive to manufacture, in which the angle between nozzle axes may be greater than 40 ° if desired.

L'invention répond notamment à ce besoin grâce à une nouvelle tête de distribution qui se caractérise par le fait qu'elle comporte un corps présentant deux logements destinés à recevoir chacun un porte-buse muni d'une buse, les logements communiquant chacun avec l'extérieur par une première ouverture et par une deuxième ouverture, chaque porte-buse étant agencé de manière à communiquer avec un conduit d'alimentation après avoir été introduit par une première ouverture, la sortie du produit s'effectuant au travers de la deuxième ouverture correspondante. The invention responds in particular to this need thanks to a new head of distribution which is characterized by the fact that it comprises a body presenting two housing intended to each receive a nozzle holder with a nozzle, housing communicating each with the outside by a first opening and a second opening, each nozzle holder being arranged to communicate with a conduit feeding after being introduced by a first opening, the product outlet effected through the corresponding second opening.

La tête de distribution selon l'invention s'avère particulièrement robuste et esthétique, tout en étant relativement simple à fabriquer, même si l'on souhaite entre les axes des buses un angle supérieur à 40°.The dispensing head according to the invention is particularly robust and aesthetic, while being relatively simple to manufacture, even if one wishes between nozzle axes an angle greater than 40 °.

Dans une réalisation particulière, lesdits logements sont réalisés dans un bouton-poussoir et ce dernier peut être relié par une partie formant charnière à une jupe de montage.In a particular embodiment, said housings are made in a pushbutton and the latter can be connected by a hinge portion to a skirt mounting.

Les buses utilisées sont avantageusement à canaux tourbillonnaires.The nozzles used are advantageously vortex channels.

Dans une réalisation particulière, chaque conduit d'alimentation avec lequel communique un porte-buse débouche dans le logement correspondant par un embout mâle ou, en variante, par un embout femelle.In a particular embodiment, each feed duct with which communicates a nozzle holder opens into the corresponding housing by a mouthpiece male or, alternatively, by a female end.

Les conduits d'alimentation sont avantageusement radiaux, ce qui facilite le démoulage.The supply ducts are advantageously radial, which facilitates the release.

Les premières ouvertures précitées peuvent être réalisées dans une paroi cylindrique de révolution, chaque deuxième ouverture pouvant être réalisée dans une paroi généralement plane.The first aforementioned openings can be made in a wall cylindrical revolution, each second opening can be performed in a generally flat wall.

Selon un aspect de l'invention, les porte-buses comportent une partie d'angle tronquée, conformée pour se positionner derrière et au contact d'un montant séparant la première l'ouverture et la deuxième ouverture correspondante.According to one aspect of the invention, the nozzle holders comprise a corner portion truncated, shaped to position itself behind and in contact with an amount separating the first opening and the corresponding second opening.

Dans une réalisation particulière, les porte-buses comportent chacun un logement dans lequel peut s'engager avec ajustement étanche un embout mâle du corps de la tête de distribution. En variante, les porte-buses comportent chacun un embout mâle apte à s'engager avec ajustement étanche dans un embout femelle du corps de la tête de distribution.In a particular embodiment, the nozzle holders each comprise a housing in which can engage with tight fitting a male end of the body of the dispensing head. In a variant, the nozzle holders each comprise a male end able to engage with tight fit in a female end of the body of the head of distribution.

Dans une réalisation particulière, chaque porte-buse comporte un center-post sur lequel peut se fixer la buse correspondante, ce center-post étant entouré par une gorge annulaire communiquant, par un canal de même axe que la buse, avec une partie de connexion apte à communiquer avec l'un des conduits d'alimentation précité.In a particular embodiment, each nozzle holder comprises a center-post on which can be fixed the corresponding nozzle, this center-post being surrounded by a throat annular communicating, by a channel of the same axis as the nozzle, with a portion of connection able to communicate with one of the aforementioned supply ducts.

Dans une réalisation particulière, les porte-buses comportent chacun une paroi cylindrique de révolution, laquelle peut s'inscrire dans la continuité du corps de la tête.In a particular embodiment, the nozzle-holders each comprise a cylindrical wall of revolution, which can be part of the continuity of the body of the head.

Les conduits d'alimentation peuvent se raccorder à un conduit axial débouchant à l'intérieur de la jupe de montage par un embout femelle servant au raccordement avec une tige de commande d'une valve ou d'une pompe.The supply ducts can be connected to an axial duct opening into the mounting skirt by a socket used for connection with a control rod of a valve or pump.

Les premières ouvertures peuvent être des ouvertures latérales et les deuxièmes ouvertures des ouvertures frontales.The first openings may be lateral openings and the second openings of the front openings.

L'invention a encore pour objet un dispositif de conditionnement et de distribution, caractérisé par le fait qu'il comporte un récipient pressurisé ou muni d'une pompe et une tête de distribution telle que définie plus haut.The subject of the invention is also a device for conditioning and distribution, characterized in that it comprises a pressurized container or equipped with a pump and a dispensing head as defined above.

L'invention a encore pour objet l'utilisation d'un tel dispositif pour la distribution d'un produit cosmétique, par exemple un déodorant, une laque ou un produit de soins sur la peau, notamment une peau à vif.The subject of the invention is also the use of such a device for dispensing a cosmetic product, for example a deodorant, a lacquer or a product care on the skin, especially raw skin.

Comme on peut le voir encore sur cette figure, le bouton-poussoir 30 comporte un conduit axial 33 d'axe X, débouchant par un embout femelle 31 à l'intérieur de la jupe de montage 50 et destiné à recevoir avec ajustement étanche l'extrémité supérieure de la tige de commande de la valve.As can be seen again in this figure, the pushbutton 30 has an axial duct 33 of X axis, opening through a female end 31 inside of the mounting skirt 50 and intended to receive with tight fit the end upper of the control rod of the valve.

Le conduit 33 se raccorde à deux conduits d'alimentation radiaux 34, débouchant par des embouts mâles respectifs 38 dans le fond de logements 35 destinés à recevoir les porte-buses 20.The duct 33 is connected to two radial supply ducts 34, opening through respective male tips 38 in the bottom of housing 35 for receive the nozzle holders 20.

Les conduits 34 s'étendent dans des directions diamétralement opposées le long d'un axe Y perpendiculaire à l'axe X. Les logements 35 communiquent avec l'extérieur par des ouvertures latérales 39 et des ouvertures frontales 41.The ducts 34 extend in diametrically opposite directions on the along a Y axis perpendicular to the X axis. The dwellings 35 communicate with the outside by lateral openings 39 and front openings 41.

Les ouvertures latérales 39 sont réalisées dans une paroi 42, cylindrique de révolution autour de l'axe X du bouton-poussoir 30, et présentent un contour généralement rectangulaire, comme on peut le voir sur la figure 2.The lateral openings 39 are made in a cylindrical wall 42 of revolution around the axis X of the pushbutton 30, and have an outline generally rectangular, as can be seen in Figure 2.

Les ouvertures frontales 41 sont réalisées chacune dans une paroi frontale 43 généralement plane, les deux parois frontales 43 se raccordant à une paroi centrale 44 s'étendant perpendiculairement à un axe Z lui-même perpendiculaire aux axes X et Y, comme on peut le voir sur la figure 3.The front openings 41 are each formed in a front wall 43 generally flat, the two end walls 43 connecting to a central wall 44 extending perpendicular to an axis Z itself perpendicular to the X and Y axes, as can be seen in Figure 3.

Les parois frontales 43 font chacune un angle d'une trentaine de degrés avec la paroi centrale 44.The end walls 43 are each at an angle of about thirty degrees with the central wall 44.

Les parois frontales 43 et centrale 44 se raccordent inférieurement à une paroi inférieure 45 qui s'étend perpendiculairement à l'axe X.The front walls 43 and central 44 are connected below a wall lower 45 which extends perpendicularly to the axis X.

Un pont de matière sécable 48 peut éventuellement relier la paroi cylindrique 42 à la partie supérieure de la jupe de montage 50 pour réduire les risques d'enfoncement accidentel du bouton-poussoir 30 avant la première utilisation. Ce pont de matière 48 se situe à l'opposé de la partie formant charnière 40.A bridge of breakable material 48 may possibly connect the cylindrical wall 42 at the top of the mounting skirt 50 to reduce the risk of depression accidental pushbutton 30 before the first use. This material bridge 48 is located opposite the hinge portion 40.

Les parois frontales 43 et cylindrique 42 sont réunies par des montants 49.The end walls 43 and cylindrical 42 are joined by uprights 49.

Le bouton-poussoir 30 comporte une paroi supérieure 32 qui sert de surface d'appui pour l'utilisateur.The push-button 30 has an upper wall 32 which serves as a surface support for the user.

Chaque montant 49 sépare les ouvertures frontale 41 et latérale 39 correspondantes en s'étendant entre les parois supérieure 32 et inférieure 45 et présente une section transversale généralement triangulaire, avec une grande base parallèle à la direction Y.Each amount 49 separates the front 41 and side 39 openings correspondingly extending between the upper 32 and lower 45 and present walls a generally triangular cross section, with a large base parallel to the direction Y.

Lors du moulage, les montants 49 sont au contact de deux tiroirs du moule déplacés l'un dans la direction Y et l'autre dans la direction Z.When molding, the uprights 49 are in contact with two drawers of the mold moved one in the Y direction and the other in the Z direction.

On va maintenant décrire en référence à la figure 5 un porte-buse 20. Celui-ci comporte un corps 21 réalisé d'un seul tenant par moulage de matière plastique. Le porte-buse 20 est pourvu d'un logement 22 destiné à recevoir avec ajustement étanche l'un des embouts mâles 38 précités et un center-post 23 (ou tige-support) dont la face avant 24 s'étend en retrait d'une face frontale 25 du porte-buse 20.We will now describe with reference to Figure 5 a nozzle holder 20. This one comprises a body 21 made in one piece by molding plastic material. The nozzle holder 20 is provided with a housing 22 for sealingly receiving one of the male tips 38 above and a center-post 23 (or support rod) whose front face 24 extends back from a front face 25 of the nozzle holder 20.

Une gorge annulaire 26 entoure le center-post 23, pour permettre la fixation de la buse 10, comme illustré sur la figure 7. Le corps 21 du porte-buse comporte également un évidement 27, lequel permet de réaliser une économie de matière. Le porte-buse 20 présente, du côté opposé au logement 22, une paroi 28 cylindrique de révolution, destinée à s'inscrire dans la continuité de la paroi cylindrique 42 du bouton-poussoir 30, comme cela sera précisé plus loin.An annular groove 26 surrounds the center-post 23, to allow fixation of the nozzle 10, as shown in Figure 7. The body 21 of the nozzle holder comprises also a recess 27, which allows a saving of material. The nozzle holder 20 has, on the side opposite the housing 22, a cylindrical wall 28 of revolution, intended to be part of the continuity of the cylindrical wall 42 of the pushbutton 30, as will be explained below.

La gorge annulaire 26 communique avec le logement 22 par un canal 29 de même axe K que le center-post 23.The annular groove 26 communicates with the housing 22 via a channel 29 of same K axis as the center-post 23.

Chaque porte-buse 20 peut être réalisé par injection de matière thermoplastique et être facilement démoulé grâce à sa géométrie.Each nozzle holder 20 may be made by injection of material thermoplastic and be easily demolded thanks to its geometry.

Les buses 10 sont de préférence à canaux tourbillonnaires, le principe de fonctionnement de telles buses étant bien connu, notamment par l'article Aerosol Age, Volume 20, décembre 1975. Ces buses à canaux tourbillonnaires peuvent être réalisées de multiples manières, le produit étant amené de manière tangentielle dans une chambre de mélange 12 au moyen de plusieurs canaux convergents 11, comme représenté sur la figure 6, la chambre de mélange 12 communiquant par un orifice de sortie 13 avec l'extérieur.The nozzles 10 are preferably vortex channels, the principle of the operation of such nozzles being well known, in particular by the article Aerosol Age, Volume 20, December 1975. These vortex channel nozzles can be made of multiple ways, the product being brought tangentially into a chamber of mixing 12 by means of several convergent channels 11, as shown in FIG. FIG. 6, the mixing chamber 12 communicating via an outlet orifice 13 with outside.

Les canaux convergents 11 se raccordent à des canaux axiaux 14 parallèles à l'axe K de la buse et sont alimentés en produit par le canal 29 du porte-buse 20.The convergent channels 11 are connected to axial channels 14 parallel to the axis K of the nozzle and are supplied with product via the channel 29 of the nozzle holder 20.

Lorsque la buse 11 est en place sur le porte-buse 20, la face avant 24 du center-post 23 vient en appui contre le fond 16 de la buse 10, de manière à forcer le produit à circuler dans les canaux convergents 11.When the nozzle 11 is in place on the nozzle holder 20, the front face 24 of the center-post 23 bears against the bottom 16 of the nozzle 10, so as to force the produced to circulate in the convergent channels 11.

Le porte-buse 20 présente un bossage annulaire 60 en avant du center-post 23, formant saillie radialement vers l'intérieur, pour permettre l'encliquetage de la buse 10.The nozzle holder 20 has an annular boss 60 in front of the center-post 23, projecting radially inwards, to allow the snap-in of the nozzle 10.

Le cas échéant, des reliefs peuvent être réalisés sur la paroi latérale 17 de la buse 10 pour améliorer son ancrage dans le porte-buse 20.Where appropriate, reliefs may be made on the side wall 17 of the nozzle 10 to improve its anchoring in the nozzle holder 20.

On remarquera que le porte-buse 20 présente une partie d'angle 62 tronquée, prolongeant la paroi cylindrique 28 du côté de la face frontale 25.It will be noted that the nozzle holder 20 has a truncated corner portion 62, extending the cylindrical wall 28 on the side of the end face 25.

La tête de distribution 3 est fabriquée de la manière suivante. Après démoulage du bouton-poussoir 30 et de la jupe de montage 50, les porte-buses 20 équipés des buses 10 sont introduits par les ouvertures latérales 39 jusqu'à ce que les embouts mâles 38 s'engagent à force dans les logements 22 et que la partie d'angle 62 des porte-buses 20 se place derrière les montants 49.The dispensing head 3 is manufactured in the following manner. After demolding of the pushbutton 30 and the mounting skirt 50, the nozzle holders 20 equipped nozzles 10 are introduced through the lateral openings 39 until the ends males 38 engage by force in the housings 22 and that the corner portion 62 of the nozzle holders 20 is placed behind the uprights 49.

On remarquera que, en fonction de l'angle que l'on donne aux axes K des center-posts 23, il est possible de modifier l'angle entre les axes des buses 10 sans changer la forme du corps de la tête de distribution, afin de l'adapter par exemple à la nature du produit à distribuer.It will be noted that, depending on the angle given to the axes K of center-posts 23, it is possible to change the angle between the axes of the nozzles 10 without change the shape of the body of the dispensing head, to adapt it for example to the nature of the product to be distributed.

Les axes K des buses 10 peuvent ainsi faire un angle non nul avec les normales aux parois frontales 43, le cas échéant.The axes K of the nozzles 10 can thus make a non-zero angle with the normal to the front walls 43, if any.

L'angle entre les axes K des buses 10 sera choisi en fonction de la distance à laquelle on souhaite que les jets émis par les buses se rencontrent, la distance entre les orifices 12 des buses 10 pouvant par exemple être comprise entre 1,5 et 2,5 cm, par exemple voisin de 2 cm, et l'angle entre les axes K compris entre 40 et 100°, par exemple voisin de 60°.The angle between the axes K of the nozzles 10 will be chosen according to the distance to which it is desired that the jets emitted by the nozzles meet, the distance between the orifices 12 of the nozzles 10 which may for example be between 1.5 and 2.5 cm, for example example neighbor of 2 cm, and the angle between the K axes between 40 and 100 °, for example neighbor of 60 °.

Pour distribuer le produit, l'utilisateur appuie sur la paroi supérieure 32, ce qui provoque l'enfoncement du bouton-poussoir 30 et l'actionnement de la valve du récipient 2.To distribute the product, the user presses on the upper wall 32, which causes the depression of the pushbutton 30 and the actuation of the valve of the container 2.

L'utilisation de buses à canaux tourbillonnaires permet, de manière surprenante, d'obtenir un spray ayant une granulométrie voisine de celle des sprays initiaux, alors que l'on aurait pu craindre d'après l'enseignement de GB-A-2 153 444 que la rencontre des particules des jets n'entraíne une fragmentation et une diminution de leur taille.The use of swirling channel nozzles makes it possible surprisingly, to obtain a spray having a particle size similar to that of the sprays initially, although it might have been feared from GB-A-2 153 444 that the meeting of the particles of the jets causes a fragmentation and a diminution of their cut.

L'invention permet ainsi de produire un spray de laque capillaire, dont les particules ont une taille supérieure à 20 µm, ayant par exemple une granulométrie moyenne voisine de 30 µm.The invention thus makes it possible to produce a hair spray lacquer, the particles have a size larger than 20 μm, for example having a particle size distribution average close to 30 μm.

L'invention convient également à la distribution d'un déodorant.The invention is also suitable for dispensing a deodorant.

Elle s'applique encore avantageusement à la distribution d'un produit pour peaux sensibles ou sur une peau à vif, notamment un produit de soins pour traiter un coup de soleil, car le spray peut être très doux et la distribution du produit peut s'effectuer sans souffle important.It still applies advantageously to the distribution of a product for sensitive skin or on a raw skin, especially a care product to treat a blow because the spray can be very soft and the product can be dispensed without big breath.

L'invention n'est pas limitée à l'exemple qui vient d'être décrit.The invention is not limited to the example which has just been described.

En particulier, les logements recevant les buses peuvent être réalisés dans une partie de la tête de distribution fixe par rapport au récipient pressurisé.In particular, the housings receiving the nozzles can be made in a part of the dispensing head fixed relative to the pressurized container.
