Abstract

The packaging comprises a semi-rigid external body (31) one of whose ends terminates in a neck (32) forming a product outlet. An internal casing (53), formed from a supple material, receives the product and has an opening (70) mounted in the neck. A one way flow valve (50) is mounted in the neck so as to allow product outlet from the casing in response to pressure exerted on the external body walls. A second one way flow valve (60) is mounted on the body to enable, in response to product outflow from the casing, air entry into the volume between the external body and the casing. The external body is made from a single piece and has a second neck (33) defining an opening (41). The second valve is mounted on the second neck.

Description

L'invention concerne un conditionnement pour produit de consistance liquide à pâteuse, notamment pour les produits dont la conservation implique de ne pas être mis en contact avec l'air extérieur. L'invention est particulièrement adaptée pour les produits à viscosité élevée telles que des crèmes. A titre d'exemple, on peut citer certains produits utilisés dans le domaine cosmétique ou pharmaceutique, tels que des gels, dentifrices ou crèmes de soins, du type crèmes hydratantes, crèmes solaires ou crèmes anti-rides. L'invention peut également trouver application dans d'autres domaines tels que le domaine agro-alimentaire.The invention relates to a packaging for a product of liquid consistency with pasty, especially for products whose conservation implies not be in contact with the outside air. The invention is particularly suitable for high viscosity products such as creams. For example, we may cite certain products used in the cosmetic field or pharmaceutical, such as gels, toothpastes or care creams, of the type moisturizers, sunscreens or anti-wrinkle creams. The invention can also find application in other fields such as the food industry.

Typiquement de tels emballages comportent un tube extérieur présentant un orifice de distribution et une enveloppe interne en matériau souple, à l'intérieur de laquelle est disposé le produit. Le produit est distribué depuis l'enveloppe extérieure au moyen d'une pression exercée sur les parois latérales du tube extérieur. Une valve de reprise d'air portée par le tube extérieur permet une entrée d'air dans le volume compris entre le tube extérieur et l'enveloppe interne en réponse à la sortie du produit afin de compenser la perte de volume.Typically such packages include an outer tube having a dispensing orifice and an internal envelope of flexible material, inside which is arranged the product. The product is distributed from the envelope external by means of a pressure exerted on the side walls of the tube outside. An air return valve carried by the outer tube allows air intake in the volume between the outer tube and the inner envelope in response to product release to compensate for the loss of volume.

La figure 1 à laquelle il est maintenant fait référence illustre de manière schématique un conditionnement tel que décrit dans la demande de brevet EP-A-0 548 840. Ce conditionnement comporte principalement une tête de distribution 2 montée sur un épaulement 3. Il comporte également un tube extérieur 17 dont l'extrémité supérieure est montée sur la périphérie de l'épaulement, et une enveloppe interne 14 dont l'extrémité supérieure est également montée sur une paroi annulaire interne de l'épaulement 3. La tête de distribution comporte une valve à écoulement unilatéral permettant la sortie du liquide en réponse à une pression exercée sur les parois latérales du tube extérieur, mais empêchant le retour du liquide dans l'enveloppe. Le tube extérieur comporte un fond 19 sur lequel est montée une valve 21 de reprise d'air, à écoulement unilatéral pour permettre uniquement l'entrée d'air dans le volume compris entre le tube extérieur et l'enveloppe interne en réponse à une distribution de produit, permettant ainsi au tube extérieur de reprendre sa forme initiale. Selon ce document, l'enveloppe externe comporte une partie supérieure 16 rigide ou semi-rigide raccordée à l'épaulement 3 et une partie inférieure 15 constituée d'un matériau plus souple. Après qu'une quantité donnée de liquide ait été distribuée, la partie inférieure de l'enveloppe interne peut remonter dans le manchon supérieur de manière à favoriser la vidange complète du conditionnement.Figure 1 to which reference is now made illustrates schematic packaging as described in patent application EP-A-0 548 840. This packaging mainly comprises a dispensing head 2 mounted on a shoulder 3. It also includes an outer tube 17 of which the upper end is mounted on the periphery of the shoulder, and a inner casing 14, the upper end of which is also mounted on a inner annular wall of the shoulder 3. The dispensing head has a unilateral flow valve allowing the exit of the liquid in response to a pressure exerted on the side walls of the outer tube, but preventing the return of the liquid in the envelope. The outer tube has a bottom 19 on which is fitted with an air return valve 21, with one-sided flow for only allow air to enter the volume between the tube exterior and internal envelope in response to product distribution, thus allowing the outer tube to return to its original shape. According to what document, the outer envelope has a rigid or semi-rigid upper part 16 connected to the shoulder 3 and a lower part 15 consisting of a softer material. After a given amount of liquid has been dispensed, the lower part of the inner casing can go back up into the sleeve higher so as to promote complete emptying of the packaging.

Une telle configuration, même si elle contribue à résoudre un certain nombre de problèmes, présente de nombreux inconvénients. En effet, hormis l'étanchéité qui doit être assurée au niveau des valves 7 et 21, il est nécessaire également d'assurer l'étanchéité à la périphérie 20 du fond 19 et à la périphérie 11 de l'épaulement 3 de manière à assurer l'étanchéité entre le tube et l'extérieur. Cette étanchéité devra être aussi parfaite que possible de manière à ce qu'il n'y ait aucune fuite d'air à ces endroits lorsque l'on presse le tube pour distribuer le produit. En ce qui concerne l'enveloppe interne, l'étanchéité doit également être assurée au niveau de la paroi annulaire interne de l'épaulement 3 afin d'isoler complètement l'enveloppe interne du tube extérieur. Selon ce document, l'étanchéité à ces différents endroits est assurée par une soudure thermique réalisée tout autour de l'emballage. Outre le fait d'être parfois de mauvaise qualité, et d'augmenter de manière considérable le coût global de fabrication, ces soudures interdisent certains designs pour l'emballage. En effet, les angles et les rayons faibles étant quasiment interdits, l'expérience montre qu'il est difficile d'avoir des conditionnements de forme autre que circulaire ou ovale, ce qui peut être pénalisant d'un point de vue marketing.Such a configuration, even if it contributes to solving a certain number of problems, has many disadvantages. In fact, apart from the tightness which must be ensured at valves 7 and 21, it is also necessary sealing the periphery 20 of the bottom 19 and the periphery 11 of the shoulder 3 so as to seal between the tube and the outside. This sealing should be as perfect as possible so that there is no no air leaks at these places when the tube is pressed to distribute the product. With regard to the internal envelope, the seal must also be provided at the level of the internal annular wall of the shoulder 3 in order to isolate the inner shell of the outer tube completely. According to this document, sealing at these different places is ensured by thermal welding performed all around the packaging. Besides being sometimes bad quality, and dramatically increase the overall cost of manufacturing, these solders prohibit certain designs for packaging. Indeed, the angles and weak rays being almost prohibited, experience shows that it is difficult to have packaging other than circular or oval, which can be penalizing from a marketing point of view.

Par ailleurs, le retournement de la partie inférieure de l'enveloppe interne dans la partie supérieure pose un certain nombre de problèmes en raison notamment des volumes morts qui existent et qui peuvent empêcher une vidange complète du produit. De plus, en remontant dans la partie supérieure, la partie basse peut venir se plaquer contre la tête 2 et obturer l'orifice de distribution, ce qui bloque la sortie du produit. Furthermore, the inversion of the lower part of the internal envelope in the upper part poses a certain number of problems due in particular to dead volumes that exist and that can prevent a complete emptying of the product. In addition, going up in the upper part, the lower part can press against head 2 and close the dispensing orifice, which blocks the product release.

Aussi, est-ce un des objets de la présente invention que de fournir un conditionnement du type à corps extérieur/enveloppe interne ne présentant pas les inconvénients des dispositifs de la technique antérieure.It is therefore one of the objects of the present invention to provide a conditioning of the type with external body / internal envelope not presenting the disadvantages of the devices of the prior art.

C'est en particulier un objet de l'invention que de réaliser un emballage pour un produit de consistance liquide à pâteuse et dont l'étanchéité est assurée de manière simple, efficace et économique à réaliser.It is in particular an object of the invention to produce packaging for a product of liquid to pasty consistency and whose sealing is ensured simple, efficient and economical way to achieve.

C'est un autre objet de l'invention que de réaliser un conditionnement autorisant une grande variété de formes extérieures, telles que carrée, circulaire, ovale, hexagonale, etc.It is another object of the invention to produce a packaging allowing a wide variety of exterior shapes, such as square, circular, oval, hexagonal, etc.

C'est encore un autre objet de l'invention que de réaliser un conditionnement pour un produit de consistance liquide à pâteuse et permettant une vidange complète du produit.It is yet another object of the invention to produce packaging for a product of liquid to pasty consistency and allowing drainage complete product.

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 which follows.

Selon l'invention, on s'est rendu compte qu'il pouvait être avantageux pour des conditionnements du type de celui décrit précédemment de prévoir une structure à deux cols, en dépit du fait qu'un seul de ces cols n'est utilisé pour la distribution du liquide, le second col étant utilisé pour le montage de la valve de reprise d'air de sorte que l'étanchéité de tout le système est réalisée au niveau des deux cols. Ceci permet, avec un corps mono-pièce, de s'affranchir du problème des soudures périphériques des dispositifs de la technique antérieure. Le second col peut être utilisé avantageusement pour recevoir un support permettant de poser le conditionnement sur une surface plane.According to the invention, it has been realized that it could be advantageous for packaging of the type described above to provide a structure with two collars, despite the fact that only one of these collars is used for distribution liquid, the second neck being used for mounting the air return valve so that the whole system is sealed at the two necks. This allows, with a one-piece body, to get rid of the problem of peripheral welds of prior art devices. The second pass can be used advantageously to receive a support allowing to pose packaging on a flat surface.

Selon l'invention, ces objets sont atteints au moyen d'un conditionnement pour produit de consistance liquide à pâteuse comprenant:

  • a) un corps extérieur semi-rigide, déformable élastiquement, dont l'une des extrémités se termine par un premier col définissant une ouverture pour le produit;

  • c) a first unilateral flow valve mounted in leaktight manner on the first neck so as to allow the product to exit from said envelope in response to a pressure exerted on the walls of the external body; and
  • d) a second unilateral flow valve mounted in leaktight manner on the body so as to allow, in response to an outlet of product from said envelope, an air inlet in the volume between the outer body and the envelope;
    • characterized in that the outer body is made in one piece and has a second neck defining an opening, the second valve being mounted in leaktight manner on the second neck.

    Avantageusement, le corps est de forme longitudinale, lesdits premier et second cols étant situés sur les extrémités opposées du corps.Advantageously, the body is of longitudinal shape, said first and second collars being located on opposite ends of the body.

    Selon un premier mode de réalisation, une frette est montée sur le premier col, ladite frette formant un siège pour la première valve, et comportant un orifice en alignement avec la première valve et l'ouverture du premier col, la première valve comportant une base annulaire montée de manière étanche entre le bord du col et la frette. Un support peut être monté sur le second col, de manière à pouvoir maintenir le conditionnement en position verticale, ledit support formant un siège pour la seconde valve et comportant un orifice en alignement avec la seconde valve et l'ouverture du second col, la seconde valve comportant une base annulaire montée de manière étanche entre le bord du col et le support. According to a first embodiment, a hoop is mounted on the first neck, said hoop forming a seat for the first valve, and comprising an orifice alignment with the first valve and the opening of the first neck, the first valve comprising an annular base mounted in leaktight manner between the edge of the neck and the fret. A support can be mounted on the second neck, so that maintain the packaging in an upright position, said support forming a seat for the second valve and having an orifice in alignment with the second valve and the opening of the second neck, the second valve having a base annular sealingly mounted between the edge of the neck and the support.

    Le corps extérieur et l'enveloppe interne peuvent être réalisés par coextrusion soufflage de deux matériaux physico-chimiquement incompatibles. A titre d'exemple, le corps extérieur est constitué d'un matériau tel que le polyéthylène teréphatalate, le polypropylène, ou le PVC. A titre d'exemple encore, l'enveloppe interne est constituée de polyéthylène haute densité ou basse densité, ou d'un mélange des deux, de PVC souple, ou d'un complexe Polyéthylène/EVOH/Polyéthylène.The external body and the internal envelope can be produced by coextrusion blowing two physico-chemically incompatible materials. As example, the outer body is made of a material such as polyethylene terephatalate, polypropylene, or PVC.

    • FIG. 2 represents a first embodiment of the packaging according to the invention;
    • Figure 3 shows another view, partially in section of the embodiment of Figure 2;
    • Figures 4A - 4B schematically illustrate the operation of the packaging according to the invention.

    Dans le mode de réalisation de la figure 2, le conditionnement 30 selon l'invention comporte principalement un corps extérieur 31 monobloc réalisé en un matériau semi-rigide apte à se déformer élastiquement sous la pression, et à reprendre sensiblement sa forme initiale lorsque cesse la pression. Typiquement, le corps extérieur est réalisé en polyéthylène teréphatalate, polypropylène, ou PVC, etc.. Dans le mode de réalisation illustré, le corps extérieur se présente sous forme d'un tube de forme allongée comportant une paroi latérale 31 se prolongeant en chacune de ses extrémités par un col 32, 33. Chacun des cols est relié au tube par un épaulement tronconique 34, 35. L'épaulement 34 présente en sa partie adjacente au tube un décrochement annulaire 36 destiné à recevoir le bord annulaire d'une frette 37. De même, l'épaulement 35 présente un décrochement annulaire 38 de manière à recevoir le bord d'un support 39. Chacun des cols 32, 33 présente une ouverture 40, 41 alignée avec l'axe A du tube. Le bord extérieur du col 32 présente un bourrelet annulaire 42 destiné à coopérer avec un organe annulaire correspondant 43 prévu sur la frette 37 pour le montage par claquage de la frette sur le col.In the embodiment of FIG. 2, the packaging 30 according to the invention mainly comprises a one-piece outer body 31 made of a material semi-rigid able to deform elastically under pressure, and to resume substantially its initial shape when the pressure stops. Typically, the body exterior is made of polyethylene terephatalate, polypropylene, or PVC, etc. In the illustrated embodiment, the outer body is in the form of an elongated tube having a side wall 31 extending in each of its ends by a neck 32, 33. Each of the necks is connected to the tube by a frustoconical shoulder 34, 35. The shoulder 34 has in its part adjacent to the tube an annular recess 36 intended to receive the edge annular of a hoop 37. Likewise, the shoulder 35 has a recess annular 38 so as to receive the edge of a support 39. Each of the collars 32, 33 has an opening 40, 41 aligned with the axis A of the tube. The outer edge of the neck 32 has an annular bead 42 intended to cooperate with a member corresponding annular 43 provided on the hoop 37 for snap-on mounting hoop on the neck.

    La frette 37 comporte une jupe latérale extérieure présentant une partie inférieure 44 de diamètre externe sensiblement égal au diamètre extérieur du tube 31, et reliée à une partie de plus faible diamètre 45 par un épaulement tronconique 46. La partie 44 est destinée à venir en appui sur le décrochement 36 du tube. La portion 45 se termine par un plateau 71 de forme légèrement bombée et ouvert en son centre de manière à définir une ouverture 48 alignée avec l'ouverture du col 32. La frette présente également une jupe interne 49 portée par le plateau 71 et dont le diamètre interne est légèrement supérieur au diamètre externe du col 32. La jupe interne 49 présente un organe complémentaire du bourrelet 42 de manière à permettre le montage par claquage de la frette 37 sur le col 32. Une valve à écoulement unilatéral 50 est disposée entre le bord du col et la frette 37. La valve 50 est montée de manière à s'ouvrir par pivotement ou par fléchissement sous la pression du produit. La valve comporte une base annulaire 51 montée de manière à être comprimée entre le bord du col 32 et le plateau 71, assurant un montage étanche de la valve 50, et de ce fait, assurant l'étanchéité de l'enveloppe interne par rapport à l'extérieur. La valve définit ainsi un joint d'étanchéité au niveau du col. Le plateau 71 définit un siège 52 pour la valve de sorte que celle-ci ne peut s'ouvrir que de l'intérieur vers l'extérieur de manière à permettre la sortie du liquide mais à empêcher le retour du liquide dans le tube.The hoop 37 comprises an outer lateral skirt having a lower part 44 of external diameter substantially equal to the external diameter of the tube 31, and connected to a part of smaller diameter 45 by a frustoconical shoulder 46. The part 44 is intended to come to bear on the recess 36 of the tube. The portion 45 ends with a plate 71 of slightly curved and open shape in its center so as to define an opening 48 aligned with the opening of the collar 32. The hoop also has an internal skirt 49 carried by the plate 71 and whose internal diameter is slightly greater than the external diameter of the neck 32. The internal skirt 49 has a member complementary to the bead 42 of so as to allow the snap fitting of the hoop 37 on the neck 32. A unilateral flow valve 50 is disposed between the edge of the neck and the hoop 37. The valve 50 is mounted so as to open by pivoting or by deflection under product pressure. The valve has an annular base 51 mounted so as to be compressed between the edge of the neck 32 and the plate 71, ensuring a watertight mounting of the valve 50, and therefore ensuring sealing of the internal envelope relative to the exterior. The valve thus defines a seal seal at the neck. The tray 71 defines a seat 52 for the valve so that it can only open from the inside to the outside so that allow the exit of the liquid but to prevent the return of the liquid in the tube.

    Avantageusement, la frette 37 et la valve 50 sont réalisées par bi-injection d'un premier matériau rigide ou semi-rigide pour la frette et d'un second matériau souple pour la valve, lesdits premier et second matériaux étant physico-chimiquement incompatibles. Le premier matériau peut être du polypropylène, polyéthylène haute densité, ABS (copolymère d'acrylonitrile/butadiène/styrène), etc.. Pour le second matériau, on peut utiliser un élastomère thermoplastique tel qu'un mélange PP/EPDM (SANTOPRENE®) ou PP/SEBS ou un thermoplastique souple tel qu'un PVC souple ou un PEBD, etc..Advantageously, the hoop 37 and the valve 50 are produced by bi-injection of a first rigid or semi-rigid material for the hoop and a second material flexible for the valve, said first and second materials being physico-chemically incompatible. The first material can be polypropylene, high density polyethylene, ABS (acrylonitrile / butadiene / styrene copolymer), etc. For the second material, a thermoplastic elastomer such as than a PP / EPDM (SANTOPRENE®) or PP / SEBS mixture or a thermoplastic flexible such as flexible PVC or LDPE, etc.

    Le conditionnement selon l'invention comporte également une enveloppe interne 53 présentant une ouverture 70 destinée à être montée sur le col 32 du tube extérieur. A titre d'exemple, l'enveloppe peut être montée sur le col 32 par collage. L'enveloppe, destinée à recevoir le produit à conditionner, est réalisée d'une seule pièce en un matériau souple imperméable à l'air. Avantageusement, le corps extérieur 31 et l'enveloppe interne 53 peuvent être réalisés par coextrusion soufflage de deux matériaux physico-chimiquement incompatibles. A titre d'exemple, le corps extérieur est constitué d'un matériau tel que le polyéthylène teréphatalate, le polypropylène, ou le PVC. A titre d'exemple encore, l'enveloppe interne est constituée de polyéthylène haute densité ou basse densité, ou d'un mélange des deux, de PVC souple, ou d'un complexe Polyéthylène/ Copolymère d'éthylène et d'alcool vinylique/Polyéthylène (PE/ EVOH/PE).The packaging according to the invention also includes an internal envelope 53 having an opening 70 intended to be mounted on the neck 32 of the tube outside. For example, the envelope can be mounted on the neck 32 by collage. The envelope, intended to receive the product to be packaged, is produced in one piece of flexible, air-tight material. Advantageously, the external body 31 and the internal envelope 53 can be produced by blown coextrusion of two physico-chemically incompatible materials. AT As an example, the outer body is made of a material such as polyethylene terephatalate, polypropylene, or PVC. For exemple again, the internal envelope is made of high density polyethylene or low density, or a mixture of the two, flexible PVC, or a complex Polyethylene / Copolymer of ethylene and vinyl alcohol / Polyethylene (PE / EVOH / PE).

    Typiquement, l'enveloppe interne à une épaisseur pouvant varier de 0,2 mm à 0,8 mm, l'épaisseur de l'enveloppe au niveau de l'ouverture 70 et de l'extrémité opposée à l'ouverture pouvant être supérieure à l'épaisseur de l'enveloppe entre ces deux extrémités. L'épaisseur du corps extérieur varie typiquement entre 0,3 mm et 1,2 mm.Typically, the internal envelope at a thickness which can vary from 0.2 mm to 0.8 mm, the thickness of the envelope at the opening 70 and the end opposite the opening which may be greater than the thickness of the envelope between these two ends. The thickness of the outer body typically varies between 0.3 mm and 1.2 mm.

    Ainsi que représenté à la figure 2, le col 33 définit une collerette 54 ouverte en son centre et destinée à contenir l'enveloppe interne 53 à l'intérieur du tube 31. Par ailleurs, la surface externe du col 33 comporte un bourrelet 55 destiné au montage par claquage du support 39 sur le col 33. Le support 39 est de diamètre externe sensiblement égal au diamètre du tube 31. Ce support comporte un fond sensiblement plat de manière à permettre de poser le conditionnement en position verticale sur une surface plane. Le fond présente en son centre une ouverture 56 autour de laquelle est disposée une jupe interne 57 dont l'extrémité intérieure porte une partie annulaire 58 complémentaire du bourrelet 55 de manière à permettre un montage par claquage du support sur le col 33. La jupe interne 57 porte un élément annulaire ouvert en son centre et destiné à former un siège 62 pour la valve 60 de sorte que celle-ci ne puisse s'ouvrir sous la pression que de l'extérieur vers l'intérieur, permettant ainsi une entrée d'air entre le tube 31 et l'enveloppe 53 lorsque le tube reprend sa forme initiale après avoir été comprimé pour distribuer du produit. La valve comporte une base périphérique 61 montée de manière à être comprimée entre le siège 62 du support et le bord du col 33, lors du montage du support sur le col, afin de réaliser l'étanchéité du volume compris entre le corps extérieur et l'enveloppe interne par rapport à l'extérieur. Le col 33 n'est pas nécessairement de hauteur identique à la hauteur du col 32. En réalité, sa hauteur doit être seulement suffisante pour permettre le montage de la valve.As shown in Figure 2, the neck 33 defines a flange 54 open in its center and intended to contain the internal envelope 53 inside the tube 31. Furthermore, the external surface of the neck 33 includes a bead 55 intended for mounting by snap of the support 39 on the neck 33. The support 39 is of diameter outer substantially equal to the diameter of the tube 31. This support has a bottom substantially flat so as to allow the packaging to be placed in vertical position on a flat surface. The background presents in its center a opening 56 around which is disposed an internal skirt 57 whose end interior carries an annular portion 58 complementary to the bead 55 of so as to allow mounting by snap of the support on the neck 33. The skirt internal 57 carries an annular element open at its center and intended to form a seat 62 for valve 60 so that it cannot open under pressure from outside to inside, allowing air to enter between the tube 31 and the casing 53 when the tube returns to its initial shape after being tablet to dispense product. The valve has a peripheral base 61 mounted so as to be compressed between the seat 62 of the support and the edge of the neck 33, when mounting the support on the neck, in order to seal the volume between the external body and the internal envelope with respect to outside. The collar 33 is not necessarily the same height as the height collar 32. In reality, its height must be only sufficient to allow the valve mounting.

    De la même manière que pour la frette 37 et la valve 50, le support 39 et la valve 60 peuvent être réalisés par bi-injection d'un premier matériau rigide ou semi-rigide pour le support et d'un second matériau souple pour la valve, lesdits premier et second matériaux étant physico-chimiquement incompatibles. De préférence, on utilise les mêmes matériaux respectivement que pour la frette 37 et la valve 50. In the same way as for the hoop 37 and the valve 50, the support 39 and the valve 60 can be produced by bi-injection of a first rigid or semi-rigid material for the support and a second flexible material for the valve, said first and second materials being physico-chemically incompatible. Of preferably, the same materials are used respectively as for hoop 37 and valve 50.

    Avantageusement encore, le conditionnement selon l'invention comporte un capot 65 destiné à fermer l'ensemble lorsque celui-ci n'est pas utilisé. Le capot présente une jupe latérale portée par un fond 67. Lors du montage du capot sur la frette 37, le bord annulaire du capot vient en appui sur l'épaulement 46 de la frette 37. Ainsi que représenté, le capot 65 comporte un élément 68, porté par le fond 67 et destiné à appuyer sur la valve lorsque le capot est monté sur la frette, de manière à immobiliser la valve en position de fermeture. Ceci permet d'éviter tout écoulement accidentel du produit, lors de son transport notamment.Advantageously also, the packaging according to the invention comprises a cover 65 intended to close the assembly when it is not in use. The hood has a side skirt carried by a bottom 67. When mounting the cover on the hoop 37, the annular edge of the cover bears on the shoulder 46 of the hoop 37. As shown, the cover 65 comprises an element 68, carried by the bottom 67 and intended to press the valve when the cover is mounted on the hoop, so as to immobilize the valve in the closed position. This avoids any accidental discharge of the product, in particular during transport.

    Dans la position assemblée, illustrée à la figure 3, la frette 37 portant la valve 50 est montée par claquage sur le bord du col 32, lequel porte l'extrémité ouverte de l'enveloppe interne 53. Dans cette position, la base périphérique 51 de la valve 50 est comprimée entre le bord du col 32 et la frette 37, réalisant ainsi l'étanchéité au niveau du col 32. Une fois le capot 65 posé sur la frette, la valve est immobilisée. De la même manière, le support 39 portant la valve 60, est monté par claquage sur le col 33. La base périphérique 61 de la valve 60 est comprimée entre la collerette 54 et le siège 62, réalisant ainsi l'étanchéité au niveau du col 33.In the assembled position, illustrated in FIG. 3, the hoop 37 carrying the valve 50 is mounted by snap on the edge of the neck 32, which carries the open end of the inner casing 53. In this position, the peripheral base 51 of the valve 50 is compressed between the edge of the neck 32 and the hoop 37, thus achieving the seal at the neck 32. Once the cover 65 is placed on the hoop, the valve is immobilized. Likewise, the support 39 carrying the valve 60 is mounted by snap-fastening on the neck 33. The peripheral base 61 of the valve 60 is compressed between the flange 54 and the seat 62, thus achieving tightness at neck level 33.

    Les figures 4A et 4B illustrent le fonctionnement du conditionnement selon l'invention. Pour distribuer une quantité donnée de produit, l'utilisatrice appuie (flèches F) sur les parois du corps extérieur 31. Sous l'effet de la pression P, la valve de produit 50 s'ouvre vers l'extérieur (figure 4A) de manière à laisser sortir le produit. Lorsque cesse la pression sur les parois du corps extérieur 31, la valve 50 se referme. Le corps extérieur reprend sa forme initiale. Il se crée alors une dépression dans l'espace tube/enveloppe qui provoque l'ouverture de la valve de reprise d'air 60 vers l'intérieur de manière à laisser passer l'air jusqu'à ce que l'équilibre des pressions s'établisse (figure 4B). Le conditionnement est à nouveau prêt pour une nouvelle utilisation.FIGS. 4A and 4B illustrate the operation of the packaging according to the invention. To distribute a given quantity of product, the user presses (arrows F) on the walls of the external body 31. Under the effect of the pressure P, the product valve 50 opens outwards (FIG. 4A) so as to let out the product. When the pressure on the walls of the external body 31 stops, the valve 50 closes. The outer body returns to its original shape. It then creates a depression in the tube / envelope space which causes the valve to open return air 60 inwards in order to let the air pass until the pressure balance is established (Figure 4B). The packaging is new ready for new use.

    Ainsi qu'il ressort de la description détaillée qui précède, la structure mono-pièce à deux cols permet de s'affranchir des problèmes d'étanchéité des dispositifs conventionnels dans lesquels il était nécessaire de réaliser une soudure à la périphérie du fond et/ou de l'épaulement supérieur. En effet, selon l'invention, l'étanchéité du système entier est circonscrite à l'étanchéité au niveau des deux cols et est assurée par le montage approprié des valves, à chaque extrémité du conditionnement.As is apparent from the detailed description above, the one-piece structure with two collars overcomes the sealing problems of the devices in which it was necessary to carry out a welding with the periphery of the bottom and / or of the upper shoulder. According to the invention, the tightness of the entire system is limited to the tightness at both necks and is ensured by the appropriate mounting of the valves, at each end of the conditioning.

    Les modes de réalisation qui viennent d'être illustrés représentent un conditionnement de forme généralement longitudinale avec un col disposé de part et d'autre du corps. Il est évident que des formes plus compactes peuvent être envisagées, dans lesquelles les deux cols sont disposés de manière adjacente sur une même face du conditionnement.The embodiments which have just been illustrated represent a generally longitudinal packaging with a neck arranged on either side of the body. It is obvious that more compact forms can be considered, in which the two collars are arranged so adjacent on the same side of the packaging.

    Ainsi, le dispositif de conditionnement selon l'invention est tout particulièrement avantageux en ce qu'il permet avec un nombre de pièces limité d'assurer une bonne conservation du produit, en toute étanchéité, et ce pendant toute la durée de vie du produit. L'étanchéité est par ailleurs simple et économique à réaliser, puisqu'elle est assurée uniquement par le montage des valves de produit et de reprise d'air. Aucune soudure n'est nécessaire. Par ailleurs, une telle conception autorise des formes très variées pour l'emballage selon l'invention, ce qui est une caractéristique particulièrement unique pour les dispositifs de ce type à deux valves.Thus, the packaging device according to the invention is very particularly advantageous in that it allows with a limited number of parts to ensure a good conservation of the product, in all tightness, and this throughout the duration life of the product. Sealing is also simple and economical to achieve, since it is only ensured by mounting the product and air intake. No soldering is necessary. By the way, such a design allows a variety of shapes for the packaging according to the invention, which is a particularly unique feature for devices of this type with two valves.

    Dans la description qui précède, il a été fait référence à des modes de réalisation avantageux du conditionnement selon l'invention. Il est évident que de nombreuses variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing description, reference has been made to embodiments advantageous packaging according to the invention. It is obvious that many variations can be made without departing from the spirit of the invention as claimed below.
