Abstract

The nozzle (15) is a disc, made of elastic material with a central fine bore which closes up when liquid is not being forced through it. The nozzle disc is held at its edge by a sealing collar (16) which fits into a housing (2). When the delivery valve opened, the pressure of the liquid behind the disc makes it bulge forward, and the central bore opens and delivers a fine spray liquid.

Description

La présente invention concerne un récipient équipé d'une tête de distribution comportant un corps et une buse de distribution solidaire dudit corps, cette buse étant pourvue d'un orifice de distribution, pour pulvériser un produit.The present invention relates to a container equipped with a dispensing head comprising a body and a dispensing nozzle integral with said body, this nozzle being provided with a dispensing orifice, for spraying a product.

On connaít de nombreuses têtes de distribution de ce type.We know many distribution heads of this type.

Lorsque le produit qui est pulvérisé forme en séchant un dépôt solide, l'orifice de distribution a tendance à se boucher.When the product which is sprayed forms on drying a solid deposit, the orifice distribution tends to get blocked.

On a proposé dans le brevet US 3,250,474 de monter la buse à déplacement sur le corps de la tête de distribution et de réaliser sur ledit corps un pointeau destiné à obturer l'orifice de distribution lorsque la tête de distribution n'est pas utilisée.It has been proposed in US Patent 3,250,474 to mount the displacement nozzle on the body of the dispensing head and make a needle on said body intended to close the dispensing opening when the dispensing head is not in use.

On diminue ainsi le risque de bouchage de l'orifice de distribution par un résidu de produit ayant séché.This reduces the risk of blockage of the dispensing orifice by a residue of dried product.

Toutefois, la tête de distribution décrite dans ce brevet antérieur présente une structure relativement complexe.However, the dispensing head described in this prior patent has a relatively complex structure.

De plus, l'extrémité du pointeau et l'orifice de distribution ne peuvent être réalisés pour des raisons de fabrication qu'avec une section relativement importante, de sorte que cette tête de distribution connue est peu adaptée à la pulvérisation du produit avec un faible débit.In addition, the end of the needle and the dispensing orifice cannot be made for manufacturing reasons that with a relatively large section, so that this known dispensing head is not very suitable for spraying the product with low flow.

L'invention a pour objet de remédier à certains inconvénients des têtes de distribution connues.The object of the invention is to remedy certain drawbacks of the known distribution.

L'invention vise notamment à proposer un nouveau récipient équipé d'une tête de distribution qui soit de fabrication relativement simple et permette de réduire les risques de bouchage de l'orifice de distribution par un résidu de produit ayant séché.The invention aims in particular to propose a new container equipped with a dispensing head which is relatively simple to manufacture and makes it possible to reduce the risk of blockage of the dispensing orifice by a residue of dried product.

Ce nouveau récipient se caractérise par le fait que l'orifice de distribution est réalisé dans une paroi élastiquement déformable agencée pour se bomber vers l'extérieur sous l'effet de la pression du produit et par le fait que ledit orifice est agencé de telle sorte qu'il soit fermé au repos et puisse s'ouvrir par déformation de ladite paroi sous l'effet de la pression du produit en amont, au moment de la distribution du produit.This new container is characterized by the fact that the dispensing orifice is made in an elastically deformable wall arranged to bulge towards the exterior under the effect of the pressure of the product and by the fact that said orifice is arranged so that it is closed at rest and can be opened by deformation of said wall under the effect of the product pressure upstream, at the time of product distribution.

Grâce à l'invention, on dispose d'une tête de distribution relativement simple à fabriquer, dans laquelle l'orifice de distribution est fermé au repos, de sorte que le produit contenu dans la tête de distribution est empêché de sécher. Thanks to the invention, there is a relatively simple dispensing head to be manufactured, in which the dispensing orifice is closed at rest, so that the product contained in the dispensing head is prevented from drying out.

Dans une réalisation particulière, l'orifice de distribution est réalisé par perçage de ladite paroi élastiquement déformable, sans enlèvement de matière.In a particular embodiment, the dispensing orifice is produced by drilling of said elastically deformable wall, without removal of material.

On peut ainsi réaliser un orifice de distribution qui au moment de l'utilisation offre une section très petite au passage du produit, ce qui permet de distribuer ce dernier avec un débit relativement faible.It is thus possible to produce a dispensing orifice which at the time of use offers a very small section for the passage of the product, which allows to distribute this the latter with a relatively low flow rate.

Dans une réalisation particulière, la paroi élastiquement déformable est agencée pour se déformer ailleurs qu'au niveau de l'orifice de distribution sous l'effet de la pression du produit, au moment de la distribution de celui-ci.In a particular embodiment, the elastically deformable wall is arranged to deform elsewhere than at the distribution orifice under the effect of the pressure of the product, at the time of distribution thereof.

La paroi élastiquement déformable peut ainsi être agencée pour se bomber vers l'extérieur sous l'effet de la pression du produit.The elastically deformable wall can thus be arranged to bulge outward under the effect of product pressure.

Cette déformation de la paroi élastiquement déformable favorise le décollement d'un éventuel résidu de produit adhérant à la surface de celle-ci.This deformation of the elastically deformable wall promotes detachment any product residue adhering to the surface thereof.

Ainsi, on diminue encore le risque de bouchage de l'orifice de distribution et l'on maintient la buse dans un état de propreté satisfaisant.Thus, the risk of blockage of the dispensing orifice is further reduced and the nozzle is kept in a satisfactory state of cleanliness.

Dans une réalisation particulière, la paroi élastiquement déformable est constituée par un disque en élastomère.In a particular embodiment, the elastically deformable wall is constituted by an elastomeric disc.

Ce disque peut être assujetti à sa périphérie à une bague réalisée dans une matière plastique rigide.This disc can be secured at its periphery to a ring made in a rigid plastic.

Ce disque peut comporter sur sa face intérieure une nervure annulaire insérée dans une gorge de forme complémentaire réalisée sur ladite bague.This disc may have on its inner face an annular rib inserted in a groove of complementary shape made on said ring.

Dans une réalisation particulière, la paroi élastiquement déformable vient en appui, au repos, contre la face frontale d'un plot central (encore appelé center post) appartenant au corps de la tête de distribution.In a particular embodiment, the elastically deformable wall comes in support, at rest, against the front face of a central stud (also called center post) belonging to the body of the dispensing head.

Des canaux tourbillonnaires peuvent être réalisés sur la face frontale de ce plot central, en vue de conférer des caractéristiques particulières à l'écoulement traversant l'orifice de distribution.Swirl channels can be made on the front of this central block, with a view to imparting particular characteristics to the flow through the dispensing orifice.

Dans une réalisation particulière, un espace annulaire est ménagé autour du plot central servant à l'alimentation des canaux tourbillonnaires précités.In a particular embodiment, an annular space is provided around the central stud used to supply the aforementioned vortex channels.

Dans une réalisation particulière, la buse est fixée dans un logement réalisé dans le corps de la tête de distribution et dont l'ouverture présente un rétrécissement de section. In a particular embodiment, the nozzle is fixed in a housing produced in the body of the dispensing head and the opening of which has a narrowing of section.

Dans une réalisation particulière, la tête de distribution comporte un embout destiné à être monté sur la tige de commande d'une valve ou d'une pompe.In a particular embodiment, the dispensing head includes a nozzle intended to be mounted on the control rod of a valve or pump.

L'axe de l'orifice de distribution peut être perpendiculaire à l'axe de l'embout précité.The axis of the dispensing orifice can be perpendicular to the axis of the nozzle cited above.

D'autres caractéristiques et avantages de la présente invention apparaítront à la lecture de la description détaillée qui va suivre, d'un exemple non limitatif de mise en oeuvre de l'invention, et à l'examen du dessin annexé sur lequel :

  • la figure 1 est une vue schématique, en coupe axiale, d'une tête de distribution conforme à l'invention,
  • la figure 2 représente un détail de réalisation de la figure 1,
  • la figure 3 est une vue analogue à la figure 2, représentant la buse au moment de la distribution du produit,
  • la figure 4 est une coupe axiale représentant la buse isolément, avant son montage sur le corps de la tête de distribution, et
  • la figure 5 est une vue de face selon la flèche V de la figure 1 du plot central.
Other characteristics and advantages of the present invention will appear on reading the detailed description which follows, of a nonlimiting example of implementation of the invention, and on examining the appended drawing in which:
  • FIG. 1 is a schematic view, in axial section, of a dispensing head according to the invention,
  • FIG. 2 represents a detail of embodiment of FIG. 1,
  • FIG. 3 is a view similar to FIG. 2, showing the nozzle when the product is dispensed,
  • FIG. 4 is an axial section showing the nozzle in isolation, before it is mounted on the body of the dispensing head, and
  • Figure 5 is a front view along arrow V of Figure 1 of the central stud.

La tête de distribution 1 représentée sur la figure 1 comporte un corps 2 réalisé par moulage de matière plastique, de préférence une matière plastique rigide.The dispensing head 1 shown in FIG. 1 comprises a body 2 made by molding plastic, preferably a rigid plastic.

Le corps 2 comporte un embout 3 d'axe X, ouvert vers le bas, destiné au montage de la tête de distribution sur la tige de commande (non représentée) d'une valve ou d'une pompe équipant un récipient contenant un liquide, par exemple une laque capillaire.The body 2 has a tip 3 of axis X, open downwards, intended for mounting the dispensing head on the control rod (not shown) of a valve or a pump fitted to a container containing a liquid, for example a hair spray.

Ce récipient peut comporter dans le cas où il est équipé d'une valve un gaz propulseur sous pression.This container may include, if it is equipped with a gas valve pressurized propellant.

La tige de commande est destinée à être montée à force dans l'embout 3 et comporte un canal d'amenée du produit.The control rod is intended to be force-fitted into the end piece 3 and has a product supply channel.

Le corps 2 comporte une jupe extérieure 4 destinée à améliorer l'esthétique du récipient sur lequel est montée la tête de distribution.The body 2 includes an outer skirt 4 intended to improve the aesthetics of the container on which the dispensing head is mounted.

Un renfoncement 5 est réalisé sur la face supérieure du corps 2 pour servir à l'appui du doigt de l'utilisateur pressant la tête de distribution 1 afin de provoquer la distribution du produit. A recess 5 is made on the upper face of the body 2 to serve to pressing the user's finger pressing the dispensing head 1 in order to cause the product distribution.

Le corps 2 comporte un logement 6 d'axe Y perpendiculaire à l'axe X, destiné au montage d'une buse 7 que l'on a représentée isolément sur la figure 4.The body 2 comprises a housing 6 of axis Y perpendicular to the axis X, intended when mounting a nozzle 7 which is shown in isolation in FIG. 4.

Ce logement 6 est ouvert sur la face avant du corps 2 et communique par un canal 8 avec le fond de l'embout 3.This housing 6 is open on the front face of the body 2 and communicates by a channel 8 with the bottom of the nozzle 3.

Un plot central 9 d'axe Y s'étend à l'intérieur du logement 6.A central stud 9 of axis Y extends inside the housing 6.

Des canaux tourbillonnaires 10 sont réalisés sur la face frontale 11 de ce plot central 9, comme on peut le voir sur la figure 5, en vue de créer un écoulement tourbillonnaire autour de l'axe Y, de façon connue en soi.Vortex channels 10 are produced on the front face 11 of this central stud 9, as can be seen in FIG. 5, with a view to creating a flow swirling around the Y axis, in a manner known per se.

La buse 7 comporte un disque 15 réalisé dans un matériau élastomère, par exemple un élastomère thermoplastique connu sous la dénomination commerciale SANTOPRENE, assujetti de manière étanche à sa périphérie à une bague de montage 16 réalisée dans une matière plastique non élastomère.The nozzle 7 comprises a disc 15 made of an elastomeric material, by example a thermoplastic elastomer known under the trade name SANTOPRENE, tightly fixed at its periphery to a mounting ring 16 made of a non-elastomeric plastic.

Le disque 15 comporte sur sa face intérieure 17, au voisinage de sa périphérie, une nervure annulaire 18 et la bague de montage comporte sur sa face avant un décrochement cylindrique de révolution 19, dont le diamètre correspond à celui du disque 15, la face intérieure 17 du disque venant en appui dans le fond 20 de ce décrochement 19.The disc 15 has on its inner face 17, in the vicinity of its periphery, an annular rib 18 and the mounting ring has a recess on its front face cylindrical of revolution 19, the diameter of which corresponds to that of the disc 15, the inner face 17 of the disc coming to bear in the bottom 20 of this recess 19.

La bague 16 comporte dans le fond 20 du logement 19 une gorge annulaire 21 dans laquelle est insérée la nervure annulaire 18.The ring 16 has in the bottom 20 of the housing 19 an annular groove 21 into which the annular rib 18 is inserted.

Le disque 15 est percé en son centre d'un orifice 22.The disc 15 is pierced in its center with an orifice 22.

L'orifice 22 est réalisé par perçage du disque 15 sans enlèvement de matière et il est fermé au repos, grâce à l'élasticité du matériau élastomère dans lequel est réalisé le disque 15.The orifice 22 is produced by drilling the disc 15 without removing material and it is closed at rest, thanks to the elasticity of the elastomeric material in which is made disc 15.

L'ouverture du logement 6 du corps 2 de la tête de distribution comporte un bourrelet annulaire 24 définissant un rétrécissement de section et la bague 16 est mise en place par encliquetage dans le logement 6.The opening of the housing 6 of the body 2 of the dispensing head comprises a annular bead 24 defining a narrowing of section and the ring 16 is put in place by snapping into the housing 6.

Lors du montage de la buse 7, la bague 16 et le corps 2 se déforment élastiquement pour permettre le franchissement du bourrelet annulaire 24 par la bague 16.When mounting the nozzle 7, the ring 16 and the body 2 deform elastically to allow the annular bead 24 to be crossed by the ring 16.

Lorsque la buse 7 est en place, la face intérieure 17 du disque 15 vient en appui sur la face frontale 11 du plot central 9, comme on peut le voir sur la figure 2. When the nozzle 7 is in place, the inner face 17 of the disc 15 comes in support on the front face 11 of the central stud 9, as can be seen in FIG. 2.

La bague 16 présente à son extrémité avant et à sa périphérie une surface conique 26 qui vient en appui contre le flan arrière du bourrelet annulaire 24, comme on peut le voir sur la figure 2.The ring 16 has a surface at its front end and at its periphery conical 26 which bears against the rear blank of the annular bead 24, as is can see it in figure 2.

La bague 16 est ainsi immobilisée de manière étanche dans le logement 6.The ring 16 is thus immobilized in a sealed manner in the housing 6.

Pour distribuer du produit, l'utilisateur appuie sur la face supérieure de la tête de distribution 1, ce qui provoque l'enfoncement de la tige de commande et l'arrivée de produit sous pression dans le canal 8 et la gorge annulaire 27 formée entre le plot central 9 et la bague 16.To distribute the product, the user presses the upper face of the dispensing head 1, which causes the control rod to sink and the inlet of product under pressure in the channel 8 and the annular groove 27 formed between the stud central 9 and the ring 16.

Ce produit sous pression gagne les canaux tourbillonnaires 10.This pressurized product reaches the vortex channels 10.

Le disque 15 se bombe vers l'extérieur sous l'effet de la pression du produit sur sa face intérieure 17.Disc 15 bulges outward under the effect of product pressure on its inner face 17.

La déformation du disque 15 permet de détacher d'éventuels résidus de produit ayant séché, adhérant sur sa face extérieure 28, devenue converse vers l'extérieur.The deformation of the disc 15 makes it possible to detach possible product residues having dried, adhering to its external face 28, which has become converse towards the outside.

En outre, le bombement du disque 15 a tendance à ouvrir l'orifice de distribution 22, ce dernier offrant alors au passage du produit une section sensiblement circulaire augmentant vers l'extérieur, comme on peut le voir sur la figure 3.In addition, the bulging of the disc 15 tends to open the dispensing orifice. 22, the latter then offering the passage of the product a substantially circular section increasing outward, as can be seen in Figure 3.

La déformation du disque 15 est suffisante pour que le produit puisse être éjecté au travers de l'orifice 22 et être distribué par exemple sous forme de spray conique.The deformation of the disc 15 is sufficient for the product to be able to be ejected through the orifice 22 and be dispensed for example in the form of a conical spray.

On notera que la section offerte au passage du produit par l'orifice 22 reste très petite, ce qui permet de distribuer le produit avec un faible débit.It will be noted that the section offered for the passage of the product through the orifice 22 remains very small, which makes it possible to distribute the product with a low flow rate.

Lorsque l'utilisateur relâche la tête de distribution 1, le canal 8 cesse d'être alimenté et le disque 15 tend à reprendre sa configuration initiale, dans laquelle sa face extérieure 28 est sensiblement plane et perpendiculaire à l'axe Y et l'orifice 22 fermé.When the user releases the dispensing head 1, the channel 8 ceases to be powered and the disc 15 tends to resume its initial configuration, in which its face outer 28 is substantially planar and perpendicular to the Y axis and the orifice 22 closed.

La fermeture de l'orifice 22 permet d'isoler l'intérieur de la tête de distribution de l'air ambiant et d'éviter le séchage du produit dans celle-ci.Closing the orifice 22 makes it possible to isolate the interior of the dispensing head of ambient air and avoid drying of the product therein.

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 exemplary embodiment which has just been described.

On peut notamment modifier la forme des canaux d'amenée du produit en amont de l'orifice de distribution, en fonction des caractéristiques de granulométrie que l'on souhaite pour l'aérosol qui est pulvérisé. One can in particular modify the shape of the product supply channels by upstream of the dispensing orifice, depending on the particle size characteristics that one wishes for the aerosol which is sprayed.

On peut également modifier la forme de l'orifice de distribution selon la nature du produit et les caractéristiques de l'écoulement que l'on souhaite obtenir.You can also modify the shape of the dispensing orifice according to the nature of the product and the characteristics of the flow that it is desired to obtain.

On peut encore réaliser des canaux à l'intérieur de la buse.Channels can still be made inside the nozzle.

La tête de distribution peut comporter deux buses ou plus.The dispensing head may have two or more nozzles.
