Description

L'invention se rapporte à un dispositif de conditionnement d'un produit liquide et de diffusion et d'application de ce produit sous forme de mousse ou de gel. Ce dispositif sert notamment pour la diffusion et l'application de mousse fixante pour les cheveux, de mousse dépilatoire, de mousse à raser ou de gel de rasage automoussant.The invention relates to a device for packaging a liquid product and of diffusion and application of this product in the form of foam or gel. This device used in particular for the diffusion and application of fixing foam for hair, hair removal foam, shaving foam or shaving gel self-foaming.

Généralement, les dispositifs classiques de diffusion de produit liquide sous forme de mousse comportent un récipient pressurisé. Ce récipient est coiffé d'une tête de distribution comportant une valve de distribution, munie d'une tige de commande, et un organe distributeur. Cet organe comprend un embout sur lequel est encliquetée une grille terminale.Generally, conventional devices for diffusing liquid product under foam form have a pressurized container. This container is topped with a dispensing head comprising a dispensing valve, provided with a control, and a distributor. This body includes a tip on which a terminal grid is snapped on.

Lorsqu'on exerce une pression mécanique sur l'organe distributeur, ce dernier délivre le produit sous forme de mousse après passage par la grille. La présence de cet embout muni de sa grille permet une distribution dosée et localisée de la mousse.When mechanical pressure is exerted on the dispensing member, the latter delivers the product in the form of foam after passing through the grid. The presence of this nozzle fitted with its grid allows metered and localized distribution of the foam.

Malheureusement ce dispositif connu entraíne la présence de résidu de mousse sur la grille, après prélèvement de la mousse, du fait de la poursuite de la sortie de la mousse en l'absence de pression mécanique sur l'organe distributeur.Unfortunately this known device causes the presence of foam residue on the grid, after removal of the foam, due to the continuation of the exit foam in the absence of mechanical pressure on the dispensing member.

Par ailleurs, l'utilisation d'un tel distributeur de mousse nécessite l'emploi d'un applicateur annexe supplémentaire de type blaireau pour la mousse à raser ou simplement la main pour la mousse à raser, la mousse fixante pour les cheveux ou la mousse dépilatoire, ce qui alourdit l'utilisation de ce distributeur.Furthermore, the use of such a foam dispenser requires the use of a additional badger type auxiliary applicator for shaving foam or just your hand for shaving foam, hair fixing foam or depilatory foam, which increases the use of this dispenser.

On connaít par ailleurs des dispositifs diffuseurs-applicateurs de produit sous forme liquide de type déodorant ayant une constitution proche de celle des dispositifs précédents, dans lesquels l'organe de distribution comporte un matériau fritté, poreux et est exempt de grille. Un tel dispositif est notamment décrit dans le document EP-A-0 655 208. Par pression mécanique sur le matériau fritté, le produit liquide est éjecté par la valve au centre de l'organe de distribution et diffuse, par capillarité, vers l'extérieur de cet organe. Ce dernier, qui est alors imprégné de micro-gouttelettes de produit liquide, peut être utilisé comme applicateur sur la peau. Malheureusement, ce type de dispositif ne permet pas d'obtenir à partir d'un produit liquide une mousse répartie de façon uniforme sur la surface d'application. En particulier, le produit est toujours extrait sous forme liquide.We also know diffusers-applicators of product in the form deodorant type liquid having a constitution close to that of the devices previous, in which the dispensing member comprises a sintered material, porous and is free of grid. Such a device is notably described in the document EP-A-0 655 208. By mechanical pressure on the sintered material, the liquid product is ejected through the valve in the center of the dispensing member and diffuses, by capillary action, towards the outside of this organ. The latter, which is then impregnated with micro-droplets of liquid product, can be used as applicator on the skin. Unfortunately, this type of device does not allow to obtain from a liquid product a foam distributed uniformly over the application surface. In particular, the product is always extracted in the form liquid.

Il est encore connu du document US-A-4 089 609 un dispositif diffuseur-applicateur de mousse à raser correspondant au préambule de la revendication 1, et comportant comme organe applicateur une éponge, percée de deux canaux longitudinaux. L'utilisation de ce type d'applicateur présente l'inconvénient d'une diffusion non uniforme du produit sur l'applicateur et d'un contact rugueux sur la peau. En outre, l'éponge est en matériau élastiquement compressible, qui lors de l'application, peut entraíner un bouchage des canaux, les rendant inopérants. It is also known from document US-A-4 089 609 a diffuser-applicator device shaving foam corresponding to the preamble of the claim 1, and comprising as an applicator member a sponge, pierced with two longitudinal channels. Using this type of applicator has the drawback of a non-uniform distribution of the product over the applicator and a rough contact on the skin. In addition, the sponge is in elastically compressible material, which during application can cause blockage of the channels, rendering them inoperative.

Aussi, il existe le besoin d'un nouveau dispositif de conditionnement, de distribution et d'application qui permette à la fois d'avoir un contact doux sur la peau grâce à un organe applicateur approprié, une distribution canalisée du produit mousseux lorsqu'on exerce notamment une pression mécanique sur l'organe applicateur et un arrêt de sortie de produit lorsque cesse cette pression mécanique. On pallie ainsi les inconvénients de l'état de la technique liés à la nature et/ou à la structure de l'organe applicateur et/ou du dispositif dans son ensemble.Also, there is a need for a new packaging device, distribution and application which allows both to have a soft contact on the skin thanks to an appropriate applicator, a channeled distribution of sparkling product when in particular mechanical pressure is exerted on the applicator member and a product outlet stop when this pressure ceases mechanical. This overcomes the drawbacks of the state of the art linked to the nature and / or structure of the applicator member and / or of the device in its together.

L'invention a donc pour objet un dispositif de conditionnement, de distribution et d'application d'un produit conditionné sous forme liquide et distribué sous forme de mousse ou de gel, comprenant un récipient pressurisé renfermant le produit, une valve de commande et un organe d'application du produit, ledit organe présentant une surface externe d'application en matériau poreux et comportant, en plus des pores, au moins un canal traversant l'organe de manière à déboucher sur la surface externe d'application sous forme d'au moins un orifice, et à permettre la sortie du produit, sous forme de mousse ou de gel, sur la surface d'application, en réponse à un actionnement de la valve, caractérisé en ce que la surface externe d'application est en un matériau non déformable. Les pores du matériau formant l'organe d'application permettent de conférer à l'application sur la peau, la douceur et le confort nécessités par une telle application. Par ailleurs ils permettent une répartition uniforme du produit sur l'applicateur.The subject of the invention is therefore a device for packaging, distributing and application of a product packaged in liquid form and distributed in the form foam or gel, comprising a pressurized container containing the product, a control valve and a product application member, said member having an external application surface made of porous material and comprising, in addition to the pores, at least one through channel the organ so as to lead to the external application surface in the form at least one orifice, and to allow the product to exit, in the form of foam or gel, on the application surface, in response to actuation of the valve, characterized in that the external application surface is in one non-deformable material. The pores of the material forming the applicator member make it possible to give the application to the skin, the softness and the comfort required by such application. They also allow a uniform distribution of the product over the applicator.

Avantageusement, le canal traverse toute l'épaisseur de l'organe, l'épaisseur de l'organe étant mesurée selon un axe A sensiblement perpendiculaire à la surface d'application.Advantageously, the channel passes through the entire thickness of the organ, the thickness of the member being measured along an axis A substantially perpendicular to the surface of application.

Ce nouveau dispositif présente l'avantage d'avoir un débit important et localisé de mousse ou de gel à la sortie de l'organe d'application. Ce dispositif permet aussi l'application de la mousse ou du gel directement sur la peau au fur et à mesure de sa sortie du récipient. Un autre avantage de ce dispositif est de permettre une diffusion canalisée et homogène de la mousse ou du gel.This new device has the advantage of having a large and localized flow of foam or gel at the outlet of the applicator member. This device also allows applying the foam or gel directly to the skin as out of the container. Another advantage of this device is to allow channeled and homogeneous diffusion of the foam or gel.

Le produit en sortie du récipient peut être sous forme de gel, de mousse ou de gel automoussant. Pour assurer la sortie du produit, le récipient contient, en outre, un agent propulseur dissout ou séparé du liquide tel que de l'azote, un hydrocarbure liquéfié ou de l'air. Le liquide peut de plus contenir un agent d'expansion de mousse comme l'isobutane. L'emploi d'un propulseur permet en outre, l'apport de fraícheur sur la peau.The product leaving the container can be in the form of gel, foam or self-foaming gel. To ensure the exit of the product, the container contains, in in addition, a propellant dissolved or separated from the liquid such as nitrogen, a liquefied hydrocarbon or air. The liquid may also contain an agent foam expansion like isobutane. The use of a propellant allows in addition, the contribution of freshness on the skin.

De préférence, le dispositif comporte plusieurs orifices répartis avantageusement uniformément sur la surface de l'organe d'application. Ils peuvent être situés au centre de la surface. De préférence, ils sont répartis symétriquement autour de l'axe A.Preferably, the device comprises several orifices advantageously distributed uniformly over the surface of the applicator member. They can be located at center of the surface. Preferably, they are distributed symmetrically around axis A.

La taille des orifices peut être comprise entre 0,4 mm et 6 mm, et de préférence comprise entre 0,8 mm et 2 mm. Les orifices peuvent avoir une forme particulière. Leur taille et leur forme permettent d'obtenir, en sortie de l'organe d'application, une mousse ou un gel par exemple sous forme de bandes, de fils ou plus exactement de spaghettis.The size of the orifices can be between 0.4 mm and 6 mm, and preferably between 0.8 mm and 2 mm. The orifices may have a particular shape. Their size and shape make it possible to obtain, at the outlet of the applicator member, a foam or gel for example in the form of strips, threads or more exactly spaghetti.

La surface externe de l'organe d'application peut être constituée en un matériau fritté, poreux choisi parmi les matériaux dits 〈〈 mous 〉〉 tels que l'éthylène vinyle acétate (EVA) ou parmi des résines synthétiques telles que des polyéthylènes de haute ou basse densité, des polypropylènes ou des fluorures de polyvinyle. En variante, l'organe applicateur peut être réalisé en une mousse synthétique rigide à cellules ouvertes.The external surface of the applicator member may be made of a material sintered, porous chosen from so-called “soft” materials such as ethylene vinyl acetate (EVA) or among synthetic resins such as polyethylenes high or low density, polypropylenes or polyvinyl fluorides. In variant, the applicator member can be made of rigid synthetic foam with open cells.

La porosité de ce matériau peut être comprise entre 1µm et 300 µm et de préférence entre 10 µm et 100 µm.The porosity of this material can be between 1 µm and 300 µm and preferably between 10 µm and 100 µm.

Pour pouvoir effectuer une application de produit en toute douceur, l'organe d'application a, avantageusement, une surface d'application dont la rugosité moyenne est choisie dans une gamme allant de 0,5 µm à 100 µm, et de préférence dans une gamme allant de 6 µm à 50 µm.To be able to apply the product gently, the organ application has, advantageously, an application surface whose roughness mean is chosen from a range from 0.5 µm to 100 µm, and preferably in a range from 6 µm to 50 µm.

Une combinaison particulière de la taille et de la forme géométrique des orifices de sortie avec des valeurs de porosité du matériau fritté permet d'adapter l'organe d'application au type de produit extrait du récipient, qu'il soit un produit moussant ou automoussant (gel ou mousse).A particular combination of the size and the geometric shape of the orifices output with porosity values of the sintered material allows to adapt the applicator to the type of product extracted from the container, whether it is a product foaming or self-foaming (gel or foam).

En fonction de la consistance du produit, du nombre et de la forme des orifices ainsi que de la porosité du matériau fritté, l'épaisseur de celui-ci peut être choisie entre 0,5 mm et 20 mm, et de préférence entre 1 mm et 5 mm.Depending on the consistency of the product, the number and shape of the orifices as well as the porosity of the sintered material, the thickness thereof can be chosen between 0.5 mm and 20 mm, and preferably between 1 mm and 5 mm.

Le dispositif selon l'invention peut servir à la diffusion, à l'application de mousse à raser et de mousse dépilatoire ou encore de mousse fixante pour les cheveux.The device according to the invention can be used for diffusion, for applying foam to shave and depilatory foam or fixing foam for the hair.

L'organe d'application peut être soit fixé directement sur la valve et plus spécialement sur la tige de commande de valve ou soit à l'aide d'un support monté sur la tige de valve.The applicator can be either fixed directly on the valve and more specially on the valve control rod or either using a support mounted on the valve stem.

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 décrits en référence aux figures annexées, mais qui ne sont nullement limitatifs.The invention consists, apart from the arrangements set out above, in one number of other provisions which will be explained below, with regard to of embodiments described with reference to the appended figures, but which do not are in no way limiting.

En se reportant à la figure 1 annexée, on peut voir un dispositif de conditionnement, de distribution et d'application désigné dans son ensemble par la référence 1, présentant un axe de symétrie X et comportant un récipient 2, généralement cylindrique, pressurisé à l'aide d'un gaz propulseur et renfermant un produit liquide P. Ce récipient porte à son extrémité supérieure une coupelle 3 de valve 4 fixée au récipient par un bourrelet de sertissage 5. La valve 4 comporte sur sa partie supérieure une tige 6 de commande, creuse, sur laquelle est fixée une tête de distribution 7. Cette tête 7 est constituée d'un réceptacle ou support 8, qui s'emboíte sur la tige 6 via un manchon creux 8a. Sur le réceptacle 8, est monté un dôme 9 légèrement bombé, convexe vers l'extérieur, qui est constitué en un matériau fritté non déformable, poreux, notamment en polyéthylène, de porosité allant de 1 à 200 µm. Ce dôme 9 qui constitue l'organe d'application du produit sur la peau est traversé par un ou plusieurs canaux 10 qui permettent la sortie du produit sous forme de mousse ou gel au niveau d'orifices 10a sur la surface d'application 9a. Le dôme 9 est encastré dans le réceptacle 8. Il est possible, également, d'assurer la fixation du dôme 9 sur le support 8 au moyen d'une bague de fixation (non représentée) clipsée sur ce support. Une chambre d'expansion 13 peut être prévue entre le support 8 et le dôme 9. Selon ce mode de réalisation, les canaux sont orientés selon un axe A sensiblement perpendiculaire à la surface d'application 9a, l'axe A étant confondu avec l'axe X. Une pluralité de tels canaux 10 sont disposés autour de l'axe A.Referring to Figure 1 attached, we can see a device packaging, distribution and application designated as a whole by reference 1, having an axis of symmetry X and comprising a container 2, generally cylindrical, pressurized with a propellant gas and containing a liquid product P. This container carries at its upper end a cup 3 valve 4 fixed to the container by a crimping bead 5. The valve 4 has on its upper part a hollow control rod 6, on which is fixed a dispensing head 7.

On the receptacle 8, a slightly domed dome 9, convex towards the outside, is mounted, which is made of a non-deformable, porous sintered material, in particular polyethylene, with a porosity ranging from 1 to 200 µm. This dome 9 which constitutes the organ of application of the product on the skin is crossed by one or more channels 10 which allow the exit of the product in the form of foam or gel at the level orifices 10a on the application surface 9a. Dome 9 is embedded in the receptacle 8. It is also possible to secure the dome 9 on the support 8 by means of a fixing ring (not shown) clipped onto this support. An expansion chamber 13 can be provided between the support 8 and the dome 9. According to this embodiment, the channels are oriented along an axis A substantially perpendicular to the application surface 9a, the axis A being coincident with the axis X. A plurality of such channels 10 are arranged around the axis A.

La tige 6, le manchon 8a et le réceptacle 8 perforé définissent un canal de distribution du produit P, du récipient vers le dôme 9. Le dispositif comporte de plus un capuchon protecteur 11 destiné à protéger la surface externe du dôme de la poussière environnante. Le capuchon est emmanché sur une jupe cylindrique 12 de fixation, encliquetée sur la partie supérieure du récipient 2, éventuellement reliée par des pattes au réceptacle 8. Cet agencement est notamment décrit dans le document EP-A-0 655 208.The rod 6, the sleeve 8a and the perforated receptacle 8 define a channel for distribution of the product P, from the container to the dome 9. The device comprises plus a protective cap 11 intended to protect the external surface of the dome of the surrounding dust. The cap is fitted on a cylindrical skirt 12 for fixing, snapped onto the upper part of the container 2, possibly connected by lugs to receptacle 8. This arrangement is notably described in document EP-A-0 655 208.

Pour se servir du dispositif selon l'invention, après avoir ôté le capuchon protecteur 11, l'utilisateur exerce une pression mécanique F en appuyant sur la surface d'application 9a du dôme 9, en dehors des zones comprenant les orifices 10a ; l'organe d'application s'enfonce, et provoque, par enfoncement de la tige 6 de valve 4 l'ouverture de cette dernière. Le produit sort du récipient via la tige 6, le manchon 8a puis par l'intermédiaire des orifices 10a sous forme de mousse et s'accumule à la surface du dôme 9. On applique alors la mousse sur la peau et on utilise le dôme 9 comme applicateur et comme moyen d'étalement de la mousse sur la peau.To use the device according to the invention, after having removed the cap protector 11, the user exerts mechanical pressure F by pressing the application surface 9a of the dome 9, outside the zones comprising the orifices 10a; the applicator member sinks, and causes, by sinking the rod 6 valve 4 opening thereof. The product leaves the container via the rod 6, the sleeve 8a then via the orifices 10a in the form of foam and accumulates on the surface of the dome 9. The foam is then applied to the skin and dome 9 is used as an applicator and as a means of spreading the foam on the skin.

Le dispositif selon l'invention permet d'obtenir une quantité et une qualité de mousse suffisante et homogène, pouvant être étalée facilement et en douceur sur la peau au moyen du dôme. Ce dôme permet de s'affranchir notamment d'un blaireau dans le cas d'une mousse à raser.The device according to the invention makes it possible to obtain a quantity and a quality of sufficient and homogeneous foam, which can be spread easily and smoothly over the skin by means of the dome. This dome makes it possible to overcome in particular a badger in the case of a shaving foam.

Sur les figures 2 et 3, les éléments identiques ou jouant des rôles analogues aux éléments décrits sur la figure 1 sont désignés par les mêmes références numériques. Leur description ne sera pas reprise ou sera effectuée succinctement.In FIGS. 2 and 3, the elements identical or playing roles analogous to elements described in Figure 1 are designated by the same references digital. Their description will not be repeated or will be made succinctly.

La figure 2 montre un dispositif qui se distingue de celui de la figure 1 par le fait que la tête de distribution 7 comprend un applicateur sous forme d'une pointe 9 constituée en un matériau fritté, poreux tel que défini en figure 1. Cette pointe est emmanchée dans le manchon 8a du réceptacle 8 et présente un canal 10 débouchant d'une part, à l'extrémité inférieure de la pointe, emmanchée dans le manchon 8a, et d'autre part, sur la surface externe d'application 9a, sensiblement au voisinage de l'extrémité libre de la pointe 9. Ce réceptacle 8 a, en outre, une forme générale convexe différente de celle d'une coupelle. Le réceptacle 8 est lié localement par une charnière périphérique 12a, à la jupe de fixation 12. L'appui de la pointe 9 sur la surface à traiter provoque le basculement du réceptacle 8 autour de la charnière 12a puis l'enfoncement de la tige de valve. Le produit remonte dans le canal 10, et sort au voisinage de l'extrémité libre de la pointe 9. Un tel applicateur est utilisé à la manière d'une dent de peigne, dans le cas notamment de l'application d'un produit capillaire. Avantageusement, on monte une pluralité de telles pointes d'application (9) sur un même récipient pressurisé.Figure 2 shows a device which differs from that of Figure 1 by the fact that the dispensing head 7 comprises an applicator in the form of a tip 9 made of a sintered, porous material as defined in Figure 1. This point is fitted into the sleeve 8a of the receptacle 8 and has a channel 10 opening on the one hand, at the lower end of the point, fitted into the sleeve 8a, and on the other hand, on the external application surface 9a, substantially in the vicinity of the free end of the tip 9. This receptacle 8 has, in addition, a general convex shape different from that of a cup. Receptacle 8 is linked locally by a peripheral hinge 12a, to the fixing skirt 12. The support of the tip 9 on the surface to be treated causes the receptacle 8 to tip over around the hinge 12a then the insertion of the valve stem. The product ascends into channel 10, and exits in the vicinity of the free end of point 9. Such an applicator is used in the manner of a comb tooth, in the case including the application of a hair product. Advantageously, we climb a plurality of such application tips (9) on the same pressurized container.

La figure 3 montre un dispositif qui se distingue de celui de la figure 1 par le fait que le réceptacle 8 comporte une partie 8b en forme de coupelle, sur laquel le est encastré le dôme 9 en matériau fritté, et un canal 8c reliant le manchon 8a et la coupelle 8b. Le canal 8c forme un angle obtus avec l'axe X. Le fonctionnement est comparable à celui de la figure1. De la même manière que pour le mode de réalisation de la figure 1, les canaux 10 sont orientés selon un axe A, sensiblement perpendiculaire à la surface d'application 9a. Contrairement au mode de réalisation de la figure 1, l'axe A n'est pas confondu avec l'axe X du récipient.Figure 3 shows a device which differs from that of Figure 1 by the fact that the receptacle 8 has a cup-shaped portion 8b, on which it is embedded the dome 9 made of sintered material, and a channel 8c connecting the sleeve 8a and the cup 8b. Channel 8c forms an obtuse angle with the X axis. is comparable to that of figure1. In the same way as for the embodiment of FIG. 1, the channels 10 are oriented along an axis A, substantially perpendicular to the application surface 9a. Contrary to embodiment of FIG. 1, the axis A is not confused with the axis X of the container.

Les parties A à H de la figure 4 montrent différentes représentations de la surface externe 9a de l'organe applicateur. Les orifices 10a sont de forme et de dimension variées. Associés avec l'une ou l'autre forme de l'organe applicateur des figures 1 à 3, ils permettent la délivrance de produits spécifiquement moussant ou automoussants sous forme de spaghettis ou de bandes.Parts A to H of Figure 4 show different representations of the surface external 9a of the applicator member. The orifices 10a are of shape and various dimensions. Associated with either form of the applicator member Figures 1 to 3, they allow the delivery of products specifically foaming or self-foaming in the form of spaghetti or strips.

Ainsi, sur la partie A, les orifices 10a sont de forme ovale ou elliptique, les grands axes de chaque ovale ou chaque ellipse étant orientés parallèlement entre eux.Thus, on part A, the orifices 10a are of oval or elliptical shape, the large axes of each oval or each ellipse being oriented parallel to each other.

Sur la partie B, les orifices 10a sont de forme carrée et sont disposés symétriquement par rapport à l'axe A. Il est toutefois possible de réaliser des orifices 10a de forme rectangulaire. On part B, the orifices 10a are square in shape and are arranged symmetrically with respect to the axis A. It is however possible to carry out holes 10a of rectangular shape.

Sur la partie C, les orifices 10a ont la forme d'arcs de cercles. Ils sont répartis selon deux cercles concentriques, centrés sur l'axe A, et décalés deux à deux.On part C, the orifices 10a have the form of arcs of circles. They are distributed according to two concentric circles, centered on the axis A, and offset two by two.

Sur la partie D, les orifices 10a sont circulaires et sont disposés selon deux cercles concentriques centrés sur l'axe A.On part D, the orifices 10a are circular and are arranged in two concentric circles centered on the axis A.

Sur la partie E, les orifices 10a sont disposés selon un seul cercle, par exemple de diamètre d'environ 24 mm, centré sur l'axe A.On part E, the orifices 10a are arranged in a single circle, for example about 24 mm in diameter, centered on axis A.

Sur la partie F, les orifices 10a sont elliptiques et leurs grands axes sont parallèles entre eux.On part F, the orifices 10a are elliptical and their major axes are parallel to each other.

Sur la partie G, les orifices 10a sont circulaires et sont répartis selon deux lignes parallèles.On part G, the orifices 10a are circular and are distributed along two lines parallel.

Sur la partie H, les orifices 10a sont en forme d'étoiles et sont agencés selon une même ligne.On part H, the orifices 10a are in the form of stars and are arranged in a same line.

Sur les parties A à E, la surface d'application est de forme circulaire, alors que sur les parties F à H, elle est de forme rectangulaire.On parts A to E, the application surface is circular, while on parts F to H, it is rectangular.

La sortie d'un produit sous forme automoussante est facilitée lorsqu'on associe le dispositif selon la figure 1 à l'une des représentations schématiques de la surface 9a de l'organe d'application selon les parties A à E de la figure 4.The output of a product in self-foaming form is facilitated when the device according to Figure 1 in one of the schematic representations of the surface 9a of the applicator member according to parts A to E of FIG. 4.

Les parties A à E de la figure 5 illustrent plusieurs formes de réalisation du dôme 9, traversé par une multitude de canaux 10.Parts A to E of Figure 5 illustrate several embodiments of the dome 9, crossed by a multitude of channels 10.

Ainsi, la partie A de la figure 5 montre des canaux 10, inclinés par rapport à l'axe A (ou X, dans le cas ou les deux axes sont confondus). Ces canaux divergent de l'axe A et sont agencés selon deux cercles concentriques.Thus, part A of FIG. 5 shows channels 10, inclined relative to the axis A (or X, in the case where the two axes are combined). These channels diverge from axis A and are arranged in two concentric circles.

La partie B montre des canaux 10 inclinés, par rapport à l'axe A, ces canaux étant parallèles entre eux.Part B shows inclined channels 10, relative to the axis A, these channels being parallel to each other.

La partie C montre des canaux 10 inclinés, par rapport à l'axe A. Ces canaux inclinés convergent vers l'axe A.Part C shows channels 10 inclined, with respect to the axis A. These channels inclined converge towards axis A.

La partie D montre des canaux 10 coniques, l'ouverture du cône (ou petit diamètre) étant tournée vers la surface d'application 9a.Part D shows 10 conical channels, the opening of the cone (or small diameter) being turned towards the application surface 9a.

La partie E montre des canaux 10 coniques, l'ouverture du cône (ou petit diamètre) étant tournée vers le support du dôme.Part E shows 10 conical channels, the opening of the cone (or small diameter) being turned towards the dome support.
