Description

La présente invention a pour objet un ensemble de distribution de produit, en particulier de produit fluide ou pâteux.The present invention relates to a product distribution assembly, in particular a fluid or pasty product.

On connait différents types de distributeurs de produit ; il existe notamment des distributeurs comprenant un récipient pour le produit muni d'une embase portant un organe de distribution maintenu mécaniquement par rapport à l'embase. Par exemple, FR-A-2 554 088 décrit un organe de distribution fixé par une embase sur un récipient, FR-A-2 400 124 décrit, comme organe de distribution, une pompe manuelle fixée par une embase sur un récipient et EP-A-0 524 854 décrit une embase comportant une valve d'ouverture unidirectionnelle.We know different types of product distributors; there are in particular distributors comprising a container for the product provided with a base carrying a dispensing member mechanically held relative to the base. For example, FR-A-2 554 088 describes a dispensing member fixed by a base on a container, FR-A-2 400 124 describes, as a dispensing member, a manual pump fixed by a base on a container and EP- A-0 524 854 describes a base comprising a one-way opening valve.

Ces distributeurs peuvent être utilisés fréquemment, par exemple au moins une fois par jour ; c'est le cas particulièrement lorsque le produit à distribuer qu'ils contiennent est un produit cosmétique. Les dimensions de ces distributeurs conduisent à un encombrement qui ne rend pas aisé leur transport, dans un sac de toilette, lorsque l'usager s'absente momentanément de son domicile, un ou deux jours, par exemple, en fin de semaine.These dispensers can be used frequently, for example at least once a day; this is particularly the case when the product to be distributed that they contain is a cosmetic product. The dimensions of these dispensers lead to a space requirement which does not make it easy to transport them, in a toilet bag, when the user is temporarily away from his home, one or two days, for example, at the weekend.

La présente invention a pour but de résoudre ce problème. Elle a pour objet un ensemble de distribution qui comporte un récipient, pour le produit de consistance liquide ou pâteuse, muni d'une embase destinée à recevoir un organe de distribution, ladite embase et ledit organe de distribution comportant des moyens de maintien complémentaires permettant de solidariser et désolidariser ladite embase et ledit organe de distribution, ledit ensemble de distribution étant caractérisé par le fait qu'il comprend également un capot comportant des moyens de maintien identiques aux moyens de maintien de ladite embase, de sorte que ledit organe de distribution et ledit capot peuvent être solidarisés de manière à constituer un sous-ensemble de distribution.The present invention aims to solve this problem. It relates to a distribution assembly which comprises a container, for the product of liquid or pasty consistency, provided with a base intended to receive a distribution member, said base and said distribution member comprising complementary holding means making it possible to securing and separating said base and said distribution member, said distribution assembly being characterized in that it also comprises a cover comprising holding means identical to the means for holding said base, so that said distribution member and said hood can be joined so as to constitute a distribution sub-assembly.

Avantageusement, le capot est monté de manière amovible sur le récipient.Advantageously, the cover is removably mounted on the container.

Selon une forme de réalisation, le récipient est constitué d'un conteneur rigide et d'une poche souple soudée à l'embase, elle-même solidarisée au conteneur ; le capot est monté de manière amovible sur le fond du conteneur, le fond et le capot comportant des moyens d'accrochage complémentaires.According to one embodiment, the container consists of a rigid container and a flexible pocket welded to the base, itself secured to the container; the cover is mounted so removable on the bottom of the container, the bottom and the cover comprising additional hooking means.

Avantageusement, l'organe de distribution est une pompe à membrane ; la pompe comprend une pièce rigide, une membrane élastique et un couvercle rigide formant organe de contrainte, la membrane étant en sandwich entre la pièce rigide et le couvercle.Advantageously, the dispensing member is a membrane pump; the pump includes a rigid part, a membrane elastic and a rigid cover forming a constraint member, the membrane being sandwiched between the rigid part and the cover.

De préférence, la pompe porte une jupe cylindrique définissant avec l'embase une première chambre communiquant avec l'intérieur de la poche par des ouvertures ; la jupe est entourée par un goulot que présente l'embase, lesdits moyens de maintien étant portés respectivement par le goulot et la jupe.Preferably, the pump carries a cylindrical skirt defining with the base a first chamber communicating with the interior of the pocket by openings; the skirt is surrounded by a neck that has the base, said holding means being carried respectively by the neck and the skirt.

La membrane forme, dans sa partie centrale, un dôme qui définit avec la pièce rigide une deuxième chambre communiquant avec la première chambre par des ouvertures ménagées dans la pièce rigide ; avantageusement, une valve unidirectionnelle est disposée au droit des ouvertures.The membrane forms, in its central part, a dome which defines with the rigid part a second chamber communicating with the first chamber by openings made in the rigid part; advantageously, a one-way valve is arranged in line with the openings.

La pièce rigide présente une partie inclinée creusée d'un canal, et la membrane se termine en biseau pour former une lèvre qui coopère avec la partie inclinée, la lèvre recouvrant le canal jusqu'à son extrémité extérieure qu'elle ferme, l'extrémité intérieure du canal débouchant dans la deuxième chambre.The rigid part has an inclined part hollowed out of a channel, and the membrane ends in a bevel to form a lip which cooperates with the inclined part, the lip covering the channel to its outer end which it closes, the end interior of the canal opening into the second bedroom.

De préférence, un couvercle est prévu pour assurer la fermeture de l'embase, la pompe ayant été déposée de l'embase, le couvercle étant muni de languettes adaptées à coopèrer avec la périphérie de la membrane d'une valve unidirectionnelle disposée au droit des ouvertures de l'embase pour appliquer la membrane sur son siège, de sorte que la poche et son embase équipée du couvercle constituent une recharge stockable de produit.Preferably, a cover is provided for closing the base, the pump having been removed from the base, the cover being provided with tongues adapted to cooperate with the periphery of the membrane of a one-way valve arranged in line with the base openings to apply the membrane to its seat, so that the pocket and its base fitted with the cover constitute a storable refill of product.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire, maintenant, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur les dessins annexés.To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawings.

Sur ces dessins :

  • la figure 1 montre, partiellement en coupe, un ensemble de distribution selon l'invention ;
  • la figure 2 montre, en coupe, un sous-ensemble réalisé à partir d'éléments de l'ensemble de la figure 1 ;
  • la figure 3 est une vue en coupe partielle d'une recharge de produit pour l'ensemble de la figure 1 ;
  • la figure 4 est un détail en coupe partielle de la figure 1.
In these drawings:
  • Figure 1 shows, partially in section, a dispensing assembly according to the invention;
  • Figure 2 shows, in section, a sub-assembly made from elements of the assembly of Figure 1;
  • Figure 3 is a partial sectional view of a product refill for the assembly of Figure 1;
  • FIG. 4 is a detail in partial section of FIG. 1.

La figure 3 montre partiellement une poche 2 en matériau déformable soudée à une embase rigide 7 ; l'embase 7 est en forme de cuvette dont la concavité est tournée du côté opposé à la poche 2 l'embase 7 est munie, à l'intérieur et au centre de la cuvette, d'un goulot 15 associé à un élément partiellement élastique 50 pour constituer une valve d'ouverture unidirectionnelle ; l'élément 50 comporte une partie d'accrochage 6 sur un doigt 14 solidaire de l'embase 7 et une partie élastique 8 en forme de membrane tronconique prenant appui élastiquement contre le fond 11 de l'embase 7 ; des ouvertures 17 ménagées dans le fond 11 de l'embase 7 au droit de la valve 50 laissent sortir le produit de la poche 2 alors que la membrane 8 de la valve l'en empêche, à moins qu'une pression soit exercée sur les parois de la poche ; un couvercle 45 présente, d'une part, des moyens d'accrochage 46 coopérant avec des moyens d'accrochage complémentaires prévus sur un rebord circulaire 47 de l'embase 7 et, d'autre part, des languettes axiales 48 s'étendant jusqu'à la périphérie de la membrane 8, en sorte que, lorsque le couvercle 45 est en place sur l'embase 7, une action est exercée sur la périphérie de la membrane 8 appliquée sur son siège constitué par le fond 11 de l'embase 7 ainsi, toute sortie du produit contenu dans la poche 2 est empêchée, même si une action est exercée sur la poche 2 ; cette disposition permet de constituer une recharge de produit, stockable, la poche restant remplie de produit.Figure 3 partially shows a pocket 2 of deformable material welded to a rigid base 7; the base 7 is in the form of a bowl whose concavity is turned on the side opposite to the pocket 2 the base 7 is provided, inside and in the center of the bowl, with a neck 15 associated with a partially elastic element 50 to constitute a one-way opening valve; the element 50 comprises a hooking part 6 on a finger 14 secured to the base 7 and an elastic part 8 in the form of a frustoconical membrane bearing elastically against the bottom 11 of the base 7; openings 17 formed in the bottom 11 of the base 7 in line with the valve 50 allow the product to come out of the bag 2 while the membrane 8 of the valve prevents it, unless pressure is exerted on the pocket walls; a cover 45 has, on the one hand, hooking means 46 cooperating with complementary hooking means provided on a circular rim 47 of the base 7 and, on the other hand, axial tongues 48 extending up to '' at the periphery of the membrane 8, so that, when the cover 45 is in place on the base 7, an action is exerted on the periphery of the membrane 8 applied to its seat formed by the bottom 11 of the base 7 thus, any exit of the product contained in the bag 2 is prevented, even if an action is exerted on the bag 2; this arrangement makes it possible to constitute a refill of product, storable, the pocket remaining filled with product.

La figure 1 montre un ensemble de distribution 1 mettant en oeuvre la recharge de la figure 2 ; après que le couvercle 45 ait été oté de l'embase 7, la recharge est introduite dans un conteneur rigide 4 de forme cylindrique dont la section transversale peut avoir une forme différente de la forme circulaire, par exemple une forme ovale. Le rebord 47 de l'embase 7 constitue une collerette propre à coopérer avec le rebord 22 du conteneur 4 à sa partie supérieure. L'embase 7 et le conteneur 4 sont solidarisés par tout moyen approprié, non représenté, par exemple par claquage. Une pompe à membrane 39, comme connue en soi, est mise en place sur l'embase 7 sur laquelle elle est maintenue grâce à des moyens de maintien 18 portés par le goulot 15 de l'embase 7, la pompe elle-même portant des moyens de maintien complémentaires 16. Bien entendu, les moyens de maintien peuvent être de tout type ; dans l'exemple représenté sur les figures, ils sont constitués de quatre portions de rampes hélicoïdales ; la pompe 39 porte une jupe cylindrique 60 définissant avec l'embase 7 une première chambre 62 communiquant avec l'intérieur de la poche 2 par les ouvertures 17 ; la jupe 60 entoure le goulot 15 et les moyens de maintien complémentaires 16 de la pompe sont portés par la jupe 60.Figure 1 shows a distribution assembly 1 implementing the refill of Figure 2; after the cover 45 has been removed from the base 7, the refill is introduced into a rigid container 4 of cylindrical shape whose cross section may have a shape different from the circular shape, for example an oval shape. The rim 47 of the base 7 constitutes a collar capable of cooperating with the rim 22 of the container 4 at its upper part. The base 7 and the container 4 are secured by any suitable means, not shown, for example by breakdown. A diaphragm pump 39, as known per se, is placed on the base 7 on which it is held by means of holding means 18 carried by the neck 15 of the base 7, the pump itself carrying additional holding means 16. Of course, the holding means can be of any type; in the example shown in the figures, they consist of four portions of helical ramps; the pump 39 carries a cylindrical skirt 60 defining with the base 7 a first chamber 62 communicating with the interior of the pocket 2 through the openings 17; the skirt 60 surrounds the neck 15 and the complementary holding means 16 of the pump are carried by the skirt 60.

La pompe à membrane 39 comprend une pièce rigide 52, une membrane 53 en matériau élastique et un couvercle 59 formant organe de contrainte, la membrane 53 étant en sandwich entre la pièce rigide 52 et le couvercle 59. La pièce rigide 52 présente une partie inclinée 55 creusée d'un canal 77, comme cela est mieux visible sur la figure 4. La membrane 53 se termine en biseau de façon à former une lèvre 54 qui coopère avec la partie inclinée 55, de la pièce rigide 52, formant siège ; la lèvre 54 recouvre le canal 77 jusqu'à son extrémité extérieure où elle le ferme. Dans sa partie centrale, la membrane 53 forme un dôme 56 qui définit une deuxième chambre 61 formant un volume variable pour le produit au dessus de la pièce rigide 52. Le canal 77 débouche, par son extrémité intérieure, dans la deuxième chambre 61. Le couvercle 59 est muni d'une ouverture centrale par laquelle le dôme 56 est accessible. La deuxième chambre 61 communique avec la première chambre 62 par des ouvertures 58 ménagées dans la pièce rigide 52 et au droit desquelles est diposée une valve unidirectionnelle 51 identique à la valve 50, montée sur un doigt 57, et autorisant le produit à passer de la chambre 62 vers la chambre 61 et interdisant son passage dans le sens inverse.The membrane pump 39 comprises a rigid part 52, a membrane 53 made of elastic material and a cover 59 forming a constraining member, the membrane 53 being sandwiched between the rigid part 52 and the cover 59. The rigid part 52 has an inclined part 55 hollowed out of a channel 77, as is better visible in FIG. 4. The membrane 53 ends in a bevel so as to form a lip 54 which cooperates with the inclined part 55, of the rigid part 52, forming a seat; the lip 54 covers the channel 77 to its outer end where it closes it. In its central part, the membrane 53 forms a dome 56 which defines a second chamber 61 forming a variable volume for the product above the rigid part 52. The channel 77 opens, by its inner end, into the second chamber 61. The cover 59 is provided with a central opening through which the dome 56 is accessible. The second chamber 61 communicates with the first chamber 62 through openings 58 formed in the rigid part 52 and to the right of which there is a unidirectional valve 51 identical to the valve 50, mounted on a finger 57, and allowing the product to pass from the room 62 towards room 61 and prohibiting its passage in the opposite direction.

Le fond 11 de l'embase 7 porte des organes anti-prisonniers 27 dont la fonction, connue en elle-même, est d'empêcher les parois de la poche souple 2 de se coller l'une contre l'autre, par exemple dans leur zone médiane, et d'emprisonner dans la partie inférieure de la poche 2 une masse de produit qui ne pourra pas être éjectée ; les organes anti-prisonniers 27 sont avantageusement constitués d'ailettes longitudinales venues de moulage avec l'embase 7.The bottom 11 of the base 7 carries anti-prisoner members 27 whose function, known in itself, is to prevent the walls of the flexible bag 2 from sticking against each other, for example in their middle zone, and to trap in the lower part of the bag 2 a mass of product which cannot be ejected; the anti-prisoner members 27 advantageously consist of longitudinal fins which have come from molding with the base 7.

Le conteneur 4 est muni d'un fond 5 comportant un orifice pour établir une communication avec l'atmosphère.The container 4 is provided with a bottom 5 comprising an orifice for establishing communication with the atmosphere.

Le fond 5 présente des moyens d'accrochage pour un capot 70 ; dans l'exemple représenté sur la figure 1, ces moyens sont constitués par une rainure 66 dans laquelle viennent se loger par claquage des pions 71 prévus à la périphérie interne de la bordure d'extrémité du capot 70. Le capot 70 est adapté à recevoir la pompe 39 dans les mêmes conditions que celle-ci est reçue par l'embase 7 ; dès lors, le capot 70 comporte des pièces nécessaires à cette adaptation identiques aux pièces correspondantes de l'embase 7 : ainsi, le capot comporte notamment un rebord 78 identique au rebord 47, un goulot 72 identique au goulot 15 et des moyens de maintien 73 identiques aux moyens de maintien 18. En désolidarisant la pompe 39 et le capot 70 du conteneur 4, il est possible de solidariser ensemble le capot 70 et la pompe 39 : on obtient ainsi un sous-ensemble 80 représenté sur la figure 2. Grâce à la présente invention, on dispose donc d'un ensemble 1 de distribution en quelque sorte "à poste fixe" à usage domestique, transformable en sous-ensemble 80 "de transport" d'encombrement notablement réduit transportable facilement dans un sac de toilette.The bottom 5 has hooking means for a cover 70; in the example shown in Figure 1, these means are constituted by a groove 66 in which are housed by snapping pins 71 provided at the inner periphery of the end edge of the cover 70. The cover 70 is adapted to receive the pump 39 under the same conditions as it is received by the base 7; therefore, the cover 70 includes parts necessary for this adaptation identical to the corresponding parts of the base 7: thus, the cover includes in particular a rim 78 identical to the rim 47, a neck 72 identical to the neck 15 and holding means 73 identical to the holding means 18. By separating the pump 39 and the cover 70 from the container 4, it is possible to secure the cover 70 and the pump 39 together: a sub-assembly 80 shown in FIG. 2 is thus obtained. the present invention, there is therefore a distribution assembly 1 in a way "fixed position" for household use, convertible into a sub-assembly 80 "transport" of significantly reduced bulk easily transportable in a toiletry bag.

Pour mettre en oeuvre l'ensemble 1 "à poste fixe", l'usager exerce une action sur le dôme 56 ; grâce à l'action de la valve unidirectionnelle 51, le produit contenu dans la chambre 61 traverse le canal 77 jusqu'à l'extérieur en comprimant la lèvre 54 contre la pièce rigide 52 ; lorsque l'action sur le dôme 56 cesse, la lèvre 54 referme par son élasticité la sortie du canal 77 ; en retrouvant sa forme originale qu'il a au repos, le dôme 56 crée une dépression dans la chambre 61 et du produit vient remplir à nouveau la chambre 61 depuis la poche 2 et la chambre 62, en traversant les valves 50 et 51.To implement the assembly 1 "fixed position", the user exerts an action on the dome 56; thanks to the action of the unidirectional valve 51, the product contained in the chamber 61 crosses the channel 77 to the outside by compressing the lip 54 against the rigid part 52; when the action on the dome 56 ceases, the lip 54 closes by its elasticity the outlet of the channel 77; by returning to its original shape which it has at rest, the dome 56 creates a depression in the chamber 61 and the product comes to fill the chamber 61 again from the bag 2 and the chamber 62, by crossing the valves 50 and 51.

Lorsque le sous-ensemble 80 est constitué à partir de la pompe 39 et du capot 70, sa mise en oeuvre s'effectue de la même manière que celle décrite ci-dessus ; bien entendu, son utilisation est limitée à la quantité de produit présente dans les chambres 61 et 62 au moment de la désolidarisation de la pompe 39 de l'ensemble 1 ; cette quantité (repère 75 sur la figure 2), limitée, est suffisante pour la distribution de quelques doses du produit.When the sub-assembly 80 is formed from the pump 39 and the cover 70, its implementation is carried out in the same manner as that described above; of course, its use is limited to the quantity of product present in the chambers 61 and 62 at the time of separation of the pump 39 from the assembly 1; this quantity (reference 75 in FIG. 2), limited, is sufficient for the distribution of a few doses of the product.
