The body of the dispensing head has a lateral skirt (8), and the sleeve is attached to it with its lower edge (12) passing under the edge of the skirt, and its main portion located over the skirt's outer surface. The thickness of the sleeve is between 0.5 and 5 mm, and preferably 1-3 mm.

Description

La présente invention a trait à une tête de distribution apte à équiper un récipient contenant un produit de consistance liquide à pâteuse, notamment un produit cosmétique ou pharmaceutique.The present invention relates to a dispensing head capable of equipping a container containing a product of liquid to pasty consistency, in particular a product cosmetic or pharmaceutical.

Le brevet US-A-4 099 651 décrit une tête de distribution comprenant un élément tubulaire fixé sur le col d'un tube souple. L'élément tubulaire comporte sur au moins une partie de sa longueur, une cloison plane qui dépasse de l'élément tubulaire de manière à définir deux canaux de sortie du produit. Un manchon en matériau élastique est enfilé sur l'élément tubulaire et sur la partie de la cloison plane qui en dépasse. Le système de fermeture est constitué par le bord du manchon en matériau élastique qui repose sur les deux faces opposées de l'extrémité de ladite cloison plane. Ce bord est en contact avec la cloison lorsqu'il n'y a pas de distribution, et s'écarte de la cloison sous la poussée du produit. Le bord revient par élasticité en contact avec les faces lorsque cesse la distribution.US-A-4,099,651 describes a dispensing head comprising an element tubular attached to the neck of a flexible tube. The tubular element has on at least part of its length, a flat partition that protrudes from the element tubular so as to define two product outlet channels. A sleeve in elastic material is threaded on the tubular element and on the part of the partition plane which exceeds. The closure system consists of the edge of the sleeve of elastic material which rests on the two opposite faces of the end of said flat partition. This edge is in contact with the partition when it there is no distribution, and moves away from the partition under the push of the product. The edge returns by elasticity in contact with the faces when the distribution stops.

Dans un tel système de fermeture, le contact entre le bord du manchon et la cloison n'est assuré que par l'élasticité de la zone de bord du manchon et il en résulte une étanchéité au repos très insuffisante, en particulier lorsque le produit distribué est très visqueux.In such a closure system, the contact between the edge of the sleeve and the partition is only ensured by the elasticity of the edge area of the sleeve and it a very insufficient seal at rest results, in particular when the product distributed is very viscous.

Le brevet US-A-4 124 150 montre un ensemble de distribution comprenant un obturateur sous forme d'un organe élastiquement déformable, soumis à l'action d'un organe de contrainte ayant tendance à maintenir cet obturateur appliqué sur un siège avec lequel il coopère pour assurer l'étanchéité du contact à la fermeture. L'organe de contrainte est formé par une sorte de lame ressort en saillie extérieure, relativement encombrante. En outre, un tel système comporte un nombre de pièces incompatible avec les contraintes économiques de l'environnement industriel. US-A-4,124,150 shows a distribution assembly comprising a obturator in the form of an elastically deformable member, subjected to action of a constraint member tending to keep this shutter applied to a seat with which it cooperates to ensure the tightness of the contact to the closing. The restraining member is formed by a kind of leaf spring in relatively bulky outer projection. In addition, such a system includes a number of parts incompatible with the economic constraints of the industrial environment.

Le brevet EP 0 410 858 décrit un dispositif du même type dans lequel l'obturateur est soumis à l'action d'un organe de contrainte rigide.Patent EP 0 410 858 describes a device of the same type in which the shutter is subjected to the action of a rigid constraint member.

La plupart de ces dispositifs connus, outre les problèmes spécifiques discutés précédemment, impliquent des opérations de montage qui affectent de manière substantielle le coût de la tête de distribution.Most of these known devices, in addition to the specific problems discussed previously, involve mounting operations that affect so the cost of the distribution head.

Dans le document US 3 365 138, il est décrit une tête de distribution formée d'un élément en une seule pièce dont une première portion définit une chambre comportant des orifices et dont une seconde portion est destinée à être rabattue sur la première portion de manière à obturer sélectivement les trous. Les deux portions sont formées du même matériau, lequel matériau est élastiquement déformable, de manière à permettre le retournement évoqué ci-dessus. Ainsi, on a un élément élastiquement déformable, replié sur un "corps" qui lui aussi, est élastiquement déformable.In document US 3,365,138, there is described a dispensing head formed of a single-piece element, a first portion of which defines a chamber having orifices and a second portion of which is intended to be folded down on the first portion so as to selectively seal the holes. Both portions are made of the same material, which material is elastically deformable, so as to allow the reversal mentioned above. So, we has an elastically deformable element, folded over a "body" which is also elastically deformable.

Un des problèmes liés à la conception du dispositif décrit dans ce document tient au fait qu'il présente une inerte à l'ouverture, nettement supérieure à l'inertie du système revendiqué. En outre, la réalisation d'orifices dans un corps élastiquement déformable est rendue beaucoup plus difficile, en particulier lorsqu'il s'agit de réaliser des trous de petite section. En effet, en raison du caractère élastiquement déformable du matériau, il est nécessaire de surdimensionner les orifices, ce qui interdit la réalisation de petits orifices. Enfin, en raison de la relativement faible résistance offerte par le corps, la fermeture ne peut être assurée de manière très étanche.One of the problems related to the design of the device described in this document is to the fact that it has an inertness on opening, significantly greater than the inertia of the claimed system. In addition, the realization of orifices in a body elastically deformable is made much more difficult, in particular when it comes to making small section holes. Indeed, due to the elastically deformable nature of the material, it is necessary to oversize the holes, which prevents the creation of small holes. Finally, due to the relatively low resistance offered by the body, the closure does not can be ensured very tightly.

Aussi, est-ce un des objets de la présente invention que de fournir une tête de distribution comportant un obturateur du type de ceux discutés ci-avant, et dont le montage est simple et économique. It is therefore one of the objects of the present invention to provide a head for distribution comprising a shutter of the type of those discussed above, and the assembly is simple and economical.

C'est un autre objet de l'invention que de fournir une tête de distribution équipée d'un tel obturateur et dont l'étanchéité est réalisée de façon satisfaisante sans requérir d'organe de contrainte auxiliaire.It is another object of the invention to provide a dispensing head equipped such a shutter and whose sealing is carried out satisfactorily without require an auxiliary constraint.

D'autres objets de l'invention apparaítront de manière détaillée dans la description qui suit.Other objects of the invention will appear in detail in the description following.

Selon l'invention, ces objets sont atteints en réalisant une tête de distribution apte à équiper un récipient contenant un produit de consistance liquide à pâteuse, comprenant un corps dans lequel est ménagé un orifice de sortie du produit et un organe de fermeture pour sélectivement obturer ledit orifice, ledit organe de fermeture étant constitué d'un organe en matériau élastiquement déformable recouvrant ledit orifice et apte à s'écarter sous une pression de produit pour dégager ledit orifice et laisser passer le produit, et à revenir en position d'obturation lorsque cesse la pression, caractérisé en ce que ledit organe de fermeture est constitué d'un manchon dont une première extrémité est solidaire du corps, une seconde extrémité formant un bord libre, ledit manchon entourant le corps et étant positionné sur ledit orifice par retournement dudit bord libre sur le corps, ledit corps étant réalisé en un matériau rigide ou semi rigide.According to the invention, these objects are achieved by making a dispensing head suitable to equip a container containing a product of liquid to pasty consistency, comprising a body in which is formed a product outlet orifice and a closing member for selectively closing said orifice, said closure consisting of a member of elastically deformable material covering said orifice and able to move apart under product pressure to release the said orifice and allow the product to pass, and return to the position shutter when the pressure ceases, characterized in that said closure consists of a sleeve of which a first end is integral of the body, a second end forming a free edge, said sleeve surrounding the body and being positioned on said orifice by inverting said free edge on the body, said body being made of a rigid or semi-rigid material.

Ainsi, la configuration de l'obturateur, sous forme d'un organe élastique replié sur un corps rigide ou semi rigide contribue à auto-contraindre l'organe élastique, en particulier son bord libre, sur le corps de la tête de distribution, de sorte qu'aucun autre organe de maintien ou de contrainte auxiliaire n'est exigé pour assurer une étanchéité satisfaisante. L'organe élastique peut être monté directement sur le corps, ou peut être monté sur une pièce de montage, laquelle est montée sur le corps de la tête de distribution. Le corps, réalisé en un matériau rigide ou semi rigide, c'est à dire formant une structure qui n'est pas déformable de manière multi-directionnelle (extension, compression, torsion) à la manière d'un élastomère ou équivalent, permet d'assurer un bon positionnement du manchon élastiquement déformable, et ce tout autour du corps. L'esthétique s'en trouve de ce fait améliorée. L'inerte à l'ouverture et à la fermeture est faible. Il offre la possibilité de dimensionner les trous exactement à la dimension souhaitée.Thus, the configuration of the shutter, in the form of an elastic member folded over a rigid or semi-rigid body contributes to self-constraining the elastic member, especially its free edge, on the body of the dispensing head, so that none no other auxiliary restraint or restraint is required to ensure satisfactory sealing. The elastic member can be mounted directly on the body, or can be mounted on a mounting piece, which is mounted on the distribution head body. The body, made of a rigid or semi material rigid, i.e. forming a structure which is not deformable so multi-directional (extension, compression, twist) like an elastomer or equivalent, ensures good positioning of the sleeve elastically deformable, all around the body. The aesthetic is found this fact improved. The opening and closing inertia is low. It offers the possibility of dimensioning the holes exactly to the desired dimension.

Selon un mode de réalisation préférentiel, la tête de distribution est formée par bi-injection, surinjection ou surmoulage d'un premier matériau rigide ou semi rigide formant le corps, et d'un matériau élastiquement déformable formant ledit organe de fermeture. Ainsi, la tête, y compris l'obturateur, est réalisée en une seule opération de moulage. Il reste ensuite à retourner le bord libre du manchon sur le corps rigide ou semi-rigide, et la tête de distribution est prête pour être montée sur un récipient, et utilisée pour la distribution du produit qu'il contient.According to a preferred embodiment, the dispensing head is formed by bi-injection, overinjection or overmolding of a first rigid or semi-rigid material forming the body, and of an elastically deformable material forming said member closing. So the head, including the shutter, is made in one molding operation. It then remains to turn the free edge of the sleeve over the rigid or semi-rigid body, and the dispensing head is ready to be mounted on a container, and used for the distribution of the product it contains.

Avantageusement, ledit matériau élastiquement déformable est un élastomère naturel, synthétique ou thermoplastique, choisi parmi les copolymères styrènebutadiène, les caoutchoucs nitriles, le polychloroprène ou néoprène, le caoutchouc EPDM, les polyuréthanes, le caoutchouc de silicone et les copolymères d'éthylène-vinyl-acétate, etc.. Le corps, quant à lui, est réalisé en polypropylène, ou polyéthylène.Advantageously, said elastically deformable material is an elastomer natural, synthetic or thermoplastic, chosen from copolymers styrene butadiene, nitrile rubbers, polychloroprene or neoprene, EPDM rubber, polyurethanes, silicone rubber and ethylene-vinyl-acetate copolymers, etc. The body, meanwhile, is made of polypropylene, or polyethylene.

Selon un mode de réalisation tout particulièrement avantageux, la tête de distribution est constituée d'un corps cylindrique, comprenant une jupe latérale dont une extrémité ouverte forme un bord libre, ledit organe d'obturation étant constitué d'un manchon disposé, avant retournement, sensiblement dans le prolongement de ladite jupe latérale, ladite première extrémité du manchon étant disposée à l'intérieur de la jupe latérale, au voisinage dudit bord libre. Ainsi, en position repliée du manchon, celui-ci vient recouvrir le bord libre du corps, ce qui assure à cet endroit, lorsque la tête est montée sur un récipient, une étanchéité pouvant parfaire l'étanchéité de l'ensemble. En outre, le manchon, en prenant appui sur le bord libre de la jupe latérale du corps, se positionne parfaitement par rapport au corps.According to a particularly advantageous embodiment, the head of distribution consists of a cylindrical body, comprising a side skirt one open end of which forms a free edge, said closure member being consisting of a sleeve disposed, before turning, substantially in the extension of said side skirt, said first end of the sleeve being disposed inside the side skirt, in the vicinity of said free edge. So in folded position of the sleeve, it covers the free edge of the body, which ensures at this point, when the head is mounted on a container, a seal can complete the tightness of the whole. In addition, the sleeve, taking support on the free edge of the side skirt of the body, is positioned perfectly by relationship to the body.

Avantageusement, le corps est formé d'une jupe latérale, dont une portion est recouverte par la partie retournée de l'organe d'obturation, ladite portion étant en retrait par rapport au reste de la jupe latérale de sorte que, en position retournée de l'organe d'obturation, celui-ci soit situé dans l'alignement du reste de la jupe latérale. On améliore ainsi l'esthétique de la tête de distribution.Advantageously, the body is formed of a side skirt, a portion of which is covered by the inverted part of the obturation member, said portion being in withdrawal from the rest of the side skirt so that, in the inverted position of the shutter member, this is located in alignment with the rest of the skirt lateral. This improves the aesthetics of the dispensing head.

Les parois du manchon peuvent avoir une épaisseur comprise entre 0,5 mm et 5 mm, et de préférence, entre 1 mm et 3 mm.The walls of the sleeve may have a thickness of between 0.5 mm and 5 mm, and preferably between 1 mm and 3 mm.

Avantageusement, le bord libre du manchon présente une excroissance formant une lèvre qui, après retournement du bord libre est disposée en regard dudit orifice. Cette excroissance formant une lèvre permet de mieux localiser la sortie du produit.Advantageously, the free edge of the sleeve has a protrusion forming a lip which, after turning over the free edge is arranged opposite said orifice. This protrusion forming a lip makes it possible to better locate the outlet of the product.

En position d'obturation, ledit organe de fermeture peut obturer de manière étanche ledit orifice. Dans cette configuration, en position de fermeture, l'organe élastique est en appui sur un siège rigide formé par le corps tout autour du ou des orifices de sortie.In the closed position, said closure member can close so sealing said orifice. In this configuration, in the closed position, the member elastic is supported on a rigid seat formed by the body all around the one or more outlet ports.

Selon une variante, en position d'obturation, ledit organe de fermeture permet une reprise d'air à l'intérieur du récipient.Alternatively, in the closed position, said closure member allows a air intake inside the container.

La tête de distribution peut comprendre des moyens pour recevoir un col ouvert d'un récipient à parois déformables (un tube par exemple). De tels moyens peuvent comprendre un filetage ou un bourrelet de claquage.The dispensing head may include means for receiving an open neck a container with deformable walls (a tube for example). Such means may include a thread or snap bead.

Alternativement, la tête de distribution comprend des moyens pour recevoir une tige de pompe ou de valve, surmontant une pompe ou une valve équipant ledit récipient, un passage assurant la communication entre la tige de pompe ou de valve et l'orifice de sortie, ledit corps comportant une surface d'appui pour l'actionnement de ladite pompe ou valve. Dans le cas d'une pompe ou d'une valve à enfoncement, la surface d'appui est située à l'opposé de l'extrémité ouverte du corps. Dans le cas d'une valve à basculement, la surface d'appui est constituée d'une portion latérale du corps de la tête. Alternatively, the dispensing head comprises means for receiving a pump or valve stem, surmounting a pump or valve fitted to said pump container, a passage ensuring communication between the pump rod or valve and the outlet orifice, said body comprising a bearing surface for actuation of said pump or valve. In the case of a pump or a valve when pressed in, the bearing surface is located opposite the open end of the body. In the case of a tilting valve, the bearing surface is made up of a lateral portion of the body of the head.

Selon un autre aspect de l'invention, on réalise également un ensemble de conditionnement et de distribution d'un produit de consistance liquide à pâteuse comprenant un récipient contenant le produit et une tête de distribution, caractérisé en ce la tête de distribution est conforme à l'invention.According to another aspect of the invention, a set of packaging and distribution of a liquid to pasty consistency product comprising a container containing the product and a dispensing head, characterized in that the dispensing head is in accordance with the invention.

Selon un premier mode de réalisation, le récipient comprend des parois déformables pour provoquer la sortie sous pression du produit par appui sur lesdites parois souples.According to a first embodiment, the container comprises walls deformable to cause the product to exit under pressure by pressing said flexible walls.

Selon un second mode de réalisation, le produit est conditionné sous pression dans le récipient, ledit récipient étant surmonté d'une valve dont l'actionnement est commandé par la tête de distribution.According to a second embodiment, the product is conditioned under pressure in the container, said container being surmounted by a valve whose actuation is controlled by the distribution head.

Selon un troisième mode de réalisation, le produit est mis sous pression au moyen d'une pompe à actionnement manuel surmontant ledit récipient et dont l'actionnement est commandé par la tête de distribution. Avantageusement le récipient est constitué d'une poche souple contenue à l'intérieur d'une enceinte rigide ou semi rigide.According to a third embodiment, the product is pressurized at by means of a manually operated pump surmounting said container and of which actuation is controlled by the dispensing head. Advantageously the container consists of a flexible pocket contained inside an enclosure rigid or semi rigid.

Le produit peut être un produit cosmétique ou pharmaceutique sous forme d'un lait, d'un gel, d'une crème, notamment un produit hydratant, un produit solaire, un produit de maquillage, ou un produit de soin.The product can be a cosmetic or pharmaceutical product in the form of a milk, gel, cream, especially a moisturizer, sunscreen, makeup product, or skincare product.

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 non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • les figures 1A-1D illustrent différentes vues d'un mode de réalisation préférentiel de la tête de distribution selon l'invention; et
  • les figures 2A et 2B illustrent un mode de réalisation particulier d'un ensemble de conditionnement et de distribution selon l'invention.
The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • Figures 1A-1D illustrate different views of a preferred embodiment of the dispensing head according to the invention; and
  • FIGS. 2A and 2B illustrate a particular embodiment of a packaging and distribution assembly according to the invention.

Dans le mode de réalisation des figures 1A à 1D, la tête de distribution 1 est réalisée sous forme d'un bouton poussoir apte à être monté sur une tige de valve ou de pompe. Le bouton poussoir comporte un corps cylindrique 2 d'axe X, rigide, formé d'une jupe latérale 8 dont une première extrémité 3 est fermée par une paroi légèrement inclinée 4, formant une surface d'appui pour l'actionnement d'une valve ou d'une pompe. Le corps 2 comporte une cheminée centrale 5 dont la section est apte à permettre le montage en force du bouton poussoir sur une tige de valve ou de pompe. La cheminée centrale 5 définit un passage axial débouchant sur un passage 6, disposé de manière sensiblement perpendiculaire au passage axial. Le passage 6 débouche sur un orifice de sortie 7 ménagé dans la partie supérieure de la jupe latérale 8 du corps 2. La jupe latérale 8 présente en son extrémité 9 opposée à la surface d'appui 4, un bord libre 10.In the embodiment of FIGS. 1A to 1D, the dispensing head 1 is designed as a push button suitable for mounting on a valve stem or pump. The push button comprises a cylindrical body 2 of axis X, rigid, formed of a side skirt 8 of which a first end 3 is closed by a slightly inclined wall 4, forming a bearing surface for actuation a valve or pump. The body 2 has a central chimney 5 of which the section is suitable for allowing the push button to be force-fitted on a valve or pump rod. The central chimney 5 defines an axial passage leading to a passage 6, arranged substantially perpendicularly at the axial passage. The passage 6 leads to an outlet orifice 7 formed in the upper part of the side skirt 8 of the body 2. The side skirt 8 has at its end 9 opposite the bearing surface 4, a free edge 10.

Le bouton poussoir comporte un manchon en matériau élastomérique 11 dont une extrémité 12 est solidaire de la surface intérieure de l'extrémité 9 de la jupe latérale 8. Bien que de préférence, le manchon soit monté à l'intérieur du corps, le raccordement du corps et du manchon 11 peut se situer dans une zone autre que celle illustrée dans ce mode de réalisation. Selon un mode de réalisation préférentiel, le manchon 11 et le corps 2 sont réalisés par bi-injection ou surinjection de deux matériaux compatibles, aptes par fusion, à former des liaisons physico-chimiques. A titre d'exemple, le corps est réalisé en polypropylène ou en polyéthylène. Le manchon 11 est formé d'un matériau élastomérique tel qu'un copolymère d'éthylène de propylène et d'un diène (EPDM). La surface interne de la paroi latérale 8 forme, sur la zone de raccordement du corps 2 et du manchon 11, un léger décrochement de manière à ce que le manchon ne provoque pas de surépaisseur par rapport à la surface interne de la paroi latérale 8. Typiquement, l'épaisseur de la paroi du manchon 11 est de l'ordre de 1 mm à 2 mm.The push button includes a sleeve of elastomeric material 11, one of which end 12 is integral with the inner surface of end 9 of the skirt side 8. Although preferably the sleeve is mounted inside the body, the connection of the body and the sleeve 11 may be located in an area other than that illustrated in this embodiment. According to one embodiment preferential, the sleeve 11 and the body 2 are produced by bi-injection or superinjection of two compatible materials capable of melting to form physico-chemical bonds. For example, the body is made of polypropylene or polyethylene. The sleeve 11 is formed of a material elastomeric such as a copolymer of ethylene propylene and a diene (EPDM). The internal surface of the side wall 8 forms, on the area of connection of body 2 and sleeve 11, a slight setback so as to what the sleeve does not cause an excess thickness compared to the surface internal side wall 8. Typically, the thickness of the wall of the sleeve 11 is of the order of 1 mm to 2 mm.

Le manchon 11, issu du moulage, est situé sensiblement dans l'alignement de la surface interne de la jupe latérale 8 (voir figures 1A et 1C). Le manchon 11 présente un bord libre 13 dont une portion forme une lèvre 14 qui, lorsque le manchon est replié sur le corps 2, à la manière d'une "chaussette" (voir figures 1B et 1D), vient en regard de l'orifice 7 de manière à l'obturer. Dans le mode de réalisation illustré, la lèvre est conçue de telle sorte qu'en position fermée, elle prenne appui sur une partie rigide du corps située tout autour de l'orifice 7.The sleeve 11, resulting from the molding, is located substantially in alignment with the internal surface of the side skirt 8 (see FIGS. 1A and 1C). Sleeve 11 has a free edge 13, a portion of which forms a lip 14 which, when the sleeve is folded over body 2, like a "sock" (see Figures 1B and 1D), comes opposite the orifice 7 so as to close it. In the mode of illustrated embodiment, the lip is designed so that in the closed position it take support on a rigid part of the body located all around the orifice 7.

Ainsi qu'il apparaít clairement aux figures 1A-1D, le corps 2 de la tête de distribution 1 est, au voisinage de la surface d'appui 4, de section légèrement supérieure à la section du reste de la jupe latérale 8 de sorte que, en position retournée du manchon 11 sur le corps 2, le manchon soit sensiblement dans le prolongement du bord latéral 15 de la surface d'appui 4.As it clearly appears in Figures 1A-1D, the body 2 of the head distribution 1 is, in the vicinity of the bearing surface 4, of slightly cross section greater than the section of the rest of the side skirt 8 so that, in position returned from the sleeve 11 on the body 2, the sleeve is substantially in the extension of the lateral edge 15 of the bearing surface 4.

Pour réaliser la tête de distribution selon l'invention, on moule tout d'abord le corps 2. Ensuite, on surinjecte ou surmoule le manchon 11. Après démoulage, on retourne; manuellement ou de façon mécanisée, le manchon 11 sur le corps 2 de manière à ce que la lèvre 14 obture l'orifice 7. La tête de distribution est alors prête pour être montée sur un réservoir équipé d'une valve ou d'une pompe, ou sur un tube ou autre conteneur à parois déformables. Il est évident que d'autres moyens pourraient être utilisés pour solidariser le manchon 11 du corps 2. A titre d'exemple, cette opération pourrait être réalisée par collage ou soudure.To make the dispensing head according to the invention, the mold is first of all body 2. Then, the sleeve 11 is over-injected or overmolded. return; manually or mechanically, the sleeve 11 on the body 2 of so that the lip 14 closes the orifice 7. The dispensing head is then ready to be mounted on a tank fitted with a valve or pump, or on a tube or other container with deformable walls. It is evident that others means could be used to secure the sleeve 11 of the body 2. As for example, this operation could be carried out by gluing or welding.

A la figure 2A, est représenté un ensemble de conditionnement et de distribution 100 équipé d'une tête de distribution telle que celle qui vient d'être décrite en référence aux figures 1A-1D. Typiquement, cet ensemble 100 comporte un réservoir 101 sous forme d'une poche en matériau souple, surmontée d'une tête de poche rigide 105 sur laquelle est montée fixement (par exemple par sertissage) une pompe 102. La poche est contenue à l'intérieur d'une enceinte rigide ou semi rigide 106 pourvue en son fond d'un orifice de reprise d'air 108. La pompe 102 comporte une tige émergente 103, creuse, sur laquelle est montée en force la cheminée axiale 5 du bouton poussoir. Un capot 107 est prévu pour, en position de stockage, protéger la tête de distribution. In FIG. 2A, a packaging and distribution assembly is shown. 100 fitted with a dispensing head such as that which has just been described in reference to Figures 1A-1D. Typically, this set 100 includes a tank 101 in the form of a pocket of flexible material, surmounted by a head rigid pocket 105 on which is fixedly mounted (for example by crimping) a pump 102. The pocket is contained inside a rigid or semi enclosure rigid 106 provided at its bottom with an air intake orifice 108. The pump 102 comprises an emerging rod 103, hollow, on which the force is mounted axial chimney 5 of the push button. A cover 107 is provided for, in position protect the dispensing head.

Pour distribuer une dose de produit contenu dans le réservoir 101, l'utilisatrice exerce une pression sur la surface d'appui 4, laquelle pression provoque un enfoncement de la tige de pompe 103, et, après remplissage du corps de pompe, la sortie sous pression du produit. Le produit P émerge de la tige 103, passe dans la cheminée axiale 5, le passage radial 7, et sort à l'extérieur du dispositif au travers de l'orifice 7, en écartant le bord libre de la lèvre 14. Cette position de distribution est illustrée à la figure 2B. Lorsque cesse la pression de produit, la lèvre 14 revient en position fermée contre la partie du corps délimitant l'orifice 7.To dispense a dose of product contained in reservoir 101, the user exerts pressure on the bearing surface 4, which pressure causes a depression of the pump rod 103, and, after filling the pump body, the pressure outlet of the product. Product P emerges from rod 103, passes into the axial chimney 5, the radial passage 7, and exits outside the device at through the orifice 7, spreading the free edge of the lip 14. This position of distribution is illustrated in Figure 2B. When the product pressure stops, the lip 14 returns to the closed position against the part of the body delimiting the orifice 7.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the spirit of the invention as claimed below.
