Description

"Dispositif de distribution étalée d'un produit quelconque, son procédé de fabrication et récipient en comportant application" "Device for spreading out any product, its manufacturing process and container with application"
La présente invention a essentiellement pour objet un dispositif de distribution étalée d'un produit quelconque ainsi que son procédé de fabrication.The present invention essentially relates to a spread distribution device of any product and its manufacturing process.
Elle vise également un récipient comportant application de ce dispositif. II a été proposé sur le marché depuis longtemps des distributeurs de produits liquides ou plus ou moins visqueux, tels que par exemple des produits cosmétiques, contenus dans un tube souple qui peut être comprimé pour permettre la délivrance du produit. Or, il est souvent utile et même nécessaire dans certains cas, que le produit dans le tube demeure constamment à l'abri de l'air et des pollutions atmosphériques. Autrement dit, la tête de délivrance doit être munie d'un système de délivrance sans reprise d'air, c'est-à-dire empêchant l'air d'être réaspiré dans le tube ainsi que le reliquat du produit déjà sorti.It also relates to a container comprising application of this device. It has been proposed on the market for a long time for distributors of liquid or more or less viscous products, such as for example cosmetic products, contained in a flexible tube which can be compressed to allow the delivery of the product. However, it is often useful and even necessary in certain cases, that the product in the tube remains constantly sheltered from air and atmospheric pollution. In other words, the delivery head must be provided with a delivery system without air intake, that is to say preventing the air from being sucked back into the tube as well as the residue of the product already out.
Dans ce but, la tête de délivrance du tube peut être munie d'une pompe sans reprise d'air ou encore d'une valve interdisant la réaspiration de l'air extérieur au tube.For this purpose, the delivery head of the tube can be provided with a pump without air intake or with a valve preventing the re-aspiration of air outside the tube.
Toutefois, ces systèmes ne sont pas sans présenter de nombreux inconvénients. Ils sont coûteux, leur fonctionnement est parfois aléatoire et surtout, ils ne permettent qu'une application ponctuelle du produit, c'est-à-dire qu'ils ne peuvent pas constituer une tête d'application étalée du produit sur une surface quelconque, telle que la peau par exemple.However, these systems are not without many drawbacks. They are expensive, their operation is sometimes random and above all, they only allow a one-off application of the product, that is to say that they cannot constitute a spreading head for applying the product on any surface, such as the skin for example.
La présente invention a pour but de remédier à ces inconvénients en proposant une tête de distribution de produit qui est très simple, peu coûteuse et permet, du fait de sa constitution un étalement du produit sans aucun risque en fin d'application de réaspiration de l'air extérieur, dans le réservoir contenant le produit. En outre, étant donné qu'il n'y aura pas de réaspiration d'air, un dosage précis des différents composants pouvant être contenus dans plusieurs compartiments du réservoir et dont le mélange constituera le produit à délivrer, pourra avantageusement être obtenu.The object of the present invention is to remedy these drawbacks by proposing a product dispensing head which is very simple, inexpensive and allows, by virtue of its constitution, spreading of the product without any risk at the end of re-aspiration application. outside air, in the tank containing the product. In addition, since there will be no air re-suction, a precise dosage of the various components which may be contained in several compartments of the tank and the mixture of which will constitute the product to be delivered, can advantageously be obtained.
A cet effet, l'invention a pour objet un dispositif de distribution étalée d'un produit liquide ou plus ou moins visqueux, du type comprenant une plaque ou analogue en un matériau élastomère, caractérisé en ce que ladite plaque comporte une multiplicité d'alvéoles débouchantes d'un côté de la plaque dont l'autre côté ou côté opposé, comporte une multiplicité de petits dômes dont les sommets sont chacun pourvus d'au moins une micro-valve. Suivant une autre caractéristique de ce dispositif, les micro-valves sont constituées par des petites fentes rectilignes ou en forme de croix pratiquées dans les sommets des petits dômes.To this end, the subject of the invention is a device for spreading out a liquid or more or less viscous product, of the type comprising a plate or the like made of an elastomeric material, characterized in that said plate comprises a multiplicity of cells opening out on one side of the plate, the other side or opposite side of which has a multiplicity of small domes, the summits of which are each provided with at least one micro-valve. According to another characteristic of this device, the micro-valves consist of small rectilinear or cross-shaped slits made in the tops of the small domes.
Suivant un mode de réalisation préféré, les alvéoles dans la plaque en matériau élastomère présentent une forme d'ogive à pointe dirigée vers les petites fentes.According to a preferred embodiment, the cells in the plate of elastomeric material have a shape of a pointed warhead directed towards the small slots.
On précisera encore ici que les petits dômes sont agencés suivant des lignes parallèles, en quinconce, ou non. La présente invention concerne encore un procédé de fabrication du dispositif ci-dessus, caractérisé en ce qu'après moulage en un seul bloc d'une plaque ou analogue en matériau élastomère comportant les alvéoles et les petits dômes précités, on perce simultanément tous les sommets des petits dômes à l'aide d'un plateau dont l'une des faces porte des poinçons à pointe aplatie.It will also be specified here that the small domes are arranged in parallel lines, staggered or not. The present invention also relates to a process for manufacturing the above device, characterized in that after molding in a single block of a plate or the like from an elastomeric material comprising the aforementioned cells and small domes, all the vertices are drilled simultaneously small domes using a tray, one of the faces of which carries punches with a flattened point.
Lors du perçage des petits dômes, la plaque précitée est prise en sandwich entre deux plaques dont au moins l'une est pré-percée.When drilling small domes, the aforementioned plate is sandwiched between two plates, at least one of which is pre-drilled.
Cette invention vise encore un récipient comprenant un corps en un matériau plus ou moins souple formant réservoir à un ou plusieurs compartiments et dont la tête est équipée d'un dispositif de distribution répondant aux caractéristiques ci-dessus.This invention also relates to a container comprising a body of a more or less flexible material forming a reservoir with one or more compartments and the head is equipped with a distribution device meeting the above characteristics.
Mais d'autres avantages et caractéristiques de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels •:However, other advantages and characteristics of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which:
La figure 1 est une vue en coupe horizontale du dispositif faite suivant la ligne I-I de la figure 2.FIG. 1 is a view in horizontal section of the device taken along line I-I of FIG. 2.

La figure 3 est une vue en plan et de dessous, suivant la flèche III de la figure 2, de ce dispositif.Figure 3 is a plan view and from below, according to arrow III of Figure 2, of this device.
La figure 4 est une vue en perspective des moyens essentiels utilisés pour la fabrication de ce dispositif.Figure 4 is a perspective view of the essential means used for the manufacture of this device.
La figure 5 est une vue schématique en perspective d'un récipient en forme de tube équipé du dispositif.Figure 5 is a schematic perspective view of a tube-shaped container equipped with the device.
En se reportant plus particulièrement aux figures 1 à 3, on voit qu'un dispositif de distribution étalée d'un produit liquide ou plus ou moins visqueux selon cette invention, est réalisé à partir d'une plaque 1 en un matériau souple et élastique, de préférence en un élastomère thermoplastique, par exemple celui connu sous la marque déposée "HYTREL" (Du Pont de Nemours). La plaque 1 peut également être en un élastomère de silicone.With particular reference to FIGS. 1 to 3, it can be seen that a device for spreading out a liquid or more or less viscous product according to this invention, is produced from a plate 1 made of a flexible and elastic material, preferably a thermoplastic elastomer, for example that known under the registered trademark "HYTREL" (Du Pont de Nemours). The plate 1 can also be made of a silicone elastomer.
La plaque 1 selon l'invention comporte, comme on le voit bien sur la figure 2, une multiplicité d'alvéoles 2 qui débouchent sur un côté ou une face 3 de la plaque 1, tandis que l'autre côté ou face opposée 4 de la plaque 1, constituant la face active du dispositif, comporte une multiplicité de petits dômes 5.The plate 1 according to the invention comprises, as can be seen in FIG. 2, a multiplicity of cells 2 which open on one side or one face 3 of the plate 1, while the other side or opposite face 4 of the plate 1, constituting the active face of the device, comprises a multiplicity of small domes 5.
Chaque sommet des petits dômes 5 est pourvu d'une micro-valve constituée tout simplement par une petite fente rectiligne 6 pratiquée dans ledit sommet.Each apex of the small domes 5 is provided with a microvalve constituted simply by a small rectilinear slot 6 made in said apex.
Comme il apparaît clairement sur la figure 2, chaque alvéole 2 ouverte du côté de la face 3 de la plaque 1 est fermée par un petit dôme 5 avec fente 6 et présente sensiblement la forme d'une ogive à pointe dirigée vers la petite fente 6.As it clearly appears in FIG. 2, each cell 2 open on the side of the face 3 of the plate 1 is closed by a small dome 5 with slot 6 and has substantially the shape of a pointed warhead directed towards the small slot 6.
Comme on le voit bien sur la figure 1, les petits dômes 5 sont disposés à l'intersection de deux groupes de droites équidistantes et orthogonales sur la face active 4 de la plaque en matériau élastomère thermoplastique 1, mais ils pourraient parfaitement être disposés en quinconce sur cette face active sans pour cela sortir du cadre de l'invention, comme on le voit sur les figures 4 et 5.As can be seen in FIG. 1, the small domes 5 are arranged at the intersection of two groups of equidistant and orthogonal lines on the active face 4 of the plate made of thermoplastic elastomer material 1, but they could perfectly be arranged in staggered rows on this active face without departing from the scope of the invention, as can be seen in FIGS. 4 and 5.
On décrira maintenant comment s'effectue la fabrication du dispositif de distribution décrit ci- dessus, en se reportant à la figure 4.We will now describe how the manufacturing of the dispensing device described above is carried out, with reference to FIG. 4.
On effectue tout d'abord le moulage en un seul bloc de la plaque 1 en matériau élastomère, de sorte que cette plaque, comme on le voit sur la figure 4, comportera une face active 4 avec des petits dômes 5 disposés ici en quinconce.First of all the molding is carried out in a single block of the plate 1 of elastomeric material, so that this plate, as seen in FIG. 4, will have an active face 4 with small domes 5 arranged here in staggered rows.
La plaque 1 est ensuite interposée entre deux plaques, à savoir une plaque supérieure 8 en métal ou autre matériau dur qui est pré-percée de façon à comporter une multiplicité de petits orifices rectilignes traversants 9, et une plaque inférieure 10 en un matériau tendre ou bien qui peut être en un matériau dur pré-percé lui aussi pour comporter une multiplicité de petits orifices traversants rectilignes 11 suivant un motif correspondant à celui des petits orifices rectilignes 9 de la plaque supérieure 8.The plate 1 is then interposed between two plates, namely an upper plate 8 made of metal or other hard material which is pre-drilled so as to comprise a multiplicity of small rectilinear through holes 9, and a lower plate 10 made of a soft material or although it can also be made of a hard material pre-drilled to also have a multiplicity of small rectilinear through orifices 11 in a pattern corresponding to that of the small rectilinear orifices 9 of the upper plate 8.
L'opération de perçage du sommet des petits dômes 5 de la plaque 1 peut alors s'effectuer à l'aide d'un plateau ou analogue 12 dont une face porte des poinçons 13 à pointe aplatie 14 présentant en quelque sorte la forme d'une pointe de sabre.The operation of drilling the top of the small domes 5 of the plate 1 can then be carried out using a plate or the like 12, one face of which carries punches 13 with flattened tip 14 having in a way the shape of a saber point.
Le motif que forment les poinçons 13 faisant saillie du plateau 12 correspond à celui des petits orifices 9 de la plaque supérieure 8, à celui des petits dômes en quinconce 5 de la plaque en matériau élastomère 1, et éventuellement à celui des petits orifices 11 de la plaque 10, si celle-ci, qui constitue un support de poinçonnage, est en un matériau dur tel que métal par exemple.The pattern formed by the punches 13 projecting from the plate 12 corresponds to that of the small orifices 9 of the upper plate 8, to that of the small staggered domes 5 of the plate of elastomer material 1, and possibly to that of the small orifices 11 of the plate 10, if the latter, which constitutes a punching support, is made of a hard material such as metal for example.
En abaissant le plateau 12 suivant la flèche F, les poinçons 13 traverseront la plaque supérieure 8 en passant au travers des petits orifices 9, puis perceront le sommet des petits dômes 5 pour réaliser les petits fentes rectilignes 6, et enfin traverseront la plaque- support inférieure 10, en passant au travers des petits orifices 11 si cette plaque 10 est en métal, ou bien tout simplement en traversant ladite plaque inférieure si celle-ci est en un matériau tendre.By lowering the plate 12 along the arrow F, the punches 13 will cross the upper plate 8 passing through small holes 9, then pierce the top of the small domes 5 to make the small rectilinear slots 6, and finally cross the support plate lower 10, passing through small holes 11 if this plate 10 is made of metal, or simply by crossing said lower plate if the latter is made of a soft material.
Cette opération étant faite, il suffira ensuite de retirer le plateau 12 suivant un sens inverse à celui de la flèche F. On observera ici que la plaque supérieure 8 retiendra avantageusement la plaque en matériau élastomère 1 lors du retrait du plateau 12, après perçage du sommet des petits dômes 5.This operation being done, it will then suffice to remove the plate 12 in a direction opposite to that of the arrow F. It will be observed here that the upper plate 8 advantageously retains the plate of elastomeric material 1 during the withdrawal of the plate 12, after drilling the top of the small domes 5.
Pour obtenir des fentes en forme de croix, il suffirait de procéder à un perçage supplémentaire de la plaque 1 après avoir fait pivoter le plateau 12 et les plaques 8 et 10 d'un quart de tour.To obtain cross-shaped slots, it would suffice to carry out an additional drilling of the plate 1 after having made the plate 12 and the plates 8 and 10 pivot by a quarter of a turn.
La plaque 1 étant ainsi percée et comportant par conséquent des petites fentes rectilignes 6, comme on le voit bien sur les figures 1 à 3, peut être découpée et fixée par tout moyen approprié sur un récipient 15 revêtant par exemple la forme d'un tube plus ou moins souple, et cela de façon à constituer la tête de délivrance du produit contenu dans ce récipient, comme on le voit bien sur la figure 5.The plate 1 being thus pierced and therefore comprising small rectilinear slots 6, as can be seen in Figures 1 to 3, can be cut and fixed by any suitable means on a container 15 taking for example the shape of a tube more or less flexible, and this so as to constitute the head for delivering the product contained in this container, as can be clearly seen in FIG. 5.
Plus précisément, le corps du récipient 15 forme un réservoir R comportant un seul produit à délivrer ou encore comportant plusieurs compartiments contenant des produits différents qui seront mélangés avant d'être distribués par la tête formée par la plaque 1 selon cette invention.More specifically, the body of the container 15 forms a reservoir R comprising a single product to be delivered or also comprising several compartments containing different products which will be mixed before being dispensed by the head formed by the plate 1 according to this invention.
Une compression du corps du récipient 15 permettra au produit remplissant les alvéoles 2 d'être distribué au travers des fentes 6 des petits dômes 5, et cela grâce à la déformation des petites fentes ou lèvres rectilignes 6 sous l'effet de la pression.Compression of the container body 15 will allow the product filling the cells 2 to be dispensed through the slots 6 of the small domes 5, and this thanks to the deformation of the small slots or straight lips 6 under the effect of the pressure.
En relâchant la compression sur le corps du récipient 15, les petites fentes ou lèvres 6 se refermeront élastiquement d'elles mêmes, du fait de la constitution en matériau élastomère thermoplastique de la plaque 1 et donc des petits dômes 5 qui constituent sa face active. On a donc réalisé suivant l'invention, un dispositif de distribution étalée d'un produit quelconque, ce dispositif évitant toute réaspiration de l'air extérieur dans le récipient ainsi que le reliquat du produit sorti, dès que l'on cesse l'application dudit produit. En outre, si le réservoir R comporte plusieurs compartiments de façon à délivrer ou distribuer un mélange des produits contenus dans ces compartiments, le mélange des produits ne risquera pas d'être réaspiré au fur et à mesure des applications successives. Le dispositif selon cette invention permet la distribution fiable et étalée de tout produit liquide ou plus ou moins visqueux sur une surface quelconque, comme par exemple des produits cosmétiques sur la peau.By releasing the compression on the body of the container 15, the small slots or lips 6 will close resiliently by themselves, due to the constitution of thermoplastic elastomeric material of the plate 1 and therefore of the small domes 5 which constitute its active face. We have therefore produced according to the invention, a spreading device for spreading any product, this device avoiding any re-aspiration of the outside air into the container as well as the residue of the product released, as soon as the application is stopped. of said product. In addition, if the reservoir R has several compartments so as to deliver or distribute a mixture of the products contained in these compartments, the mixture of the products will not risk being sucked back as and when successive applications. The device according to this invention allows the reliable and spread distribution of any liquid or more or less viscous product on any surface, such as for example cosmetic products on the skin.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre des revendications qui suivent. On the contrary, the invention includes all the technical equivalents of the means described as well as their combinations if these fall within the scope of the claims which follow.
