Description

La présente invention se rapporte à une capsule de fermeture et/ou de réglage du débit de produit et à un distributeur comportant un récipient de produit non compact et cette capsule.The present invention relates to a closure and / or adjustment capsule for the product flow and to a dispenser with a non-compact product container and this capsule.

Par 〈〈 non compact 〉〉 on entend un produit liquide, visqueux, pâteux voire pulvérulent.By "not compact" is meant a liquid, viscous, pasty product or even powdery.

Une telle capsule de fermeture et de réglage de débit convient notamment pour la distribution d'un ou plusieurs produits à large diffusion comme des shampooings, des dentifrices, des dépilatoires, des lotions corporelles, des antisolaires, des antiseptiques, des fards liquides, ou encore de la mayonnaise ou de la moutarde.Such a closure and flow adjustment capsule is particularly suitable for distribution of one or more widely distributed products such as shampoos, toothpaste, depilatory, body lotions, sunscreen, antiseptics, liquid eyeshadows, or mayonnaise or mustard.

En général, les produits cosmétiques, dermopharmaceutiques, alimentaires ou d'hygiène corporelle de consistance non compacte sont conditionnés dans un récipient fermé par un bouchon amovible ou par une capsule de distribution munie d'un organe de fermeture, généralement basculant. Pour la distribution du produit, l'utilisateur enlève le bouchon ou provoque l'ouverture de l'organe de fermeture de la capsule. On connaít également des capsules à ouverture par traction appelées 〈〈 capsules push-pull 〉〉.In general, cosmetic, dermopharmaceutical, food or non-compact body hygiene products are packaged in a container closed by a removable cap or by a dispensing cap fitted a closing member, generally tilting. For product distribution, the user removes the plug or causes the closure member to open the capsule. We also know capsules with pull opening called 〈〈 push-pull capsules 〉〉.

Dans le cas des récipients à bouchon amovible, on peut perdre le bouchon ; ceci entraíne alors le dessèchement ou la dégradation du produit par l'air ambiant. En outre, la plupart des capsules de fermeture habituellement utilisées ne permettent pas de faire varier, à volonté, le débit de distribution du produit.In the case of receptacles with removable caps, the cap may be lost; this then causes drying or degradation of the product by the ambient air. In In addition, most of the closure capsules usually used do not allow not to vary, at will, the product delivery rate.

La présente invention a justement pour objet une capsule de fermeture et de réglage de débit permettant de remédier à ces inconvénients.The subject of the present invention is precisely a closure capsule and flow adjustment to overcome these drawbacks.

Plus précisément, la présente invention a pour objet une capsule de fermeture et de distribution d'un ou plusieurs produits conditionnés dans un même récipient ne comportant pas de bouchon amovible, la distribution de ce produit pouvant être commandée, par l'utilisateur, par simple rotation de la capsule.More specifically, the present invention relates to a closure capsule and distribution of one or more packaged products in the same container does not with no removable cap, the distribution of this product can be controlled by the user by simple rotation of the capsule.

Un autre objet de l'invention est relatif à une capsule de distribution d'un ou plusieurs produits dont le débit de l'un ou plusieurs produits peut être réglé à volonté par l'utilisateur.Another subject of the invention relates to a dispensing capsule of one or several products whose flow of one or more products can be adjusted at will by the user.

On connaít déjà, par exemple par les documents DE-C-589 805, FR-A-968 868 correspondant au préambule de la revendication 1) ou CH-A-213 732, des capsules de distribution pour produits liquides que l'utilisateur peut commander par rotation d'une bague de fermeture/ réglage de débit, agissant sur un organe élastique traversé par un canal de distribution. Toutes ces capsules présentent deux inconvénients majeurs : d'une part l'organe élastique ne peut être fabriqué par moulage, ce qui entraíne des frais de fabrication élevés ; d'autre part, la manipulation de la bague, pour obtenir la fermeture complète du canal de distribution nécessite une rotation angulaire relativement importante. We already know, for example by documents DE-C-589 805, FR-A-968 868 corresponding to the preamble of claim 1) or CH-A-213 732, dispensing capsules for liquid products that the user can be controlled by rotation of a closing ring / flow adjustment, acting on an elastic member through which a distribution channel passes. All these capsules have two major drawbacks: on the one hand, the elastic member cannot be manufactured by molding, which results in high manufacturing costs; on the other hand, the manipulation of the ring, to obtain complete closure of the distribution requires relatively large angular rotation.

Ainsi, la présente invention a pour objet une capsule de fermeture et de réglage de débit d'un ou plusieurs produits non compacts contenus dans un récipient, comportant un organe de fermeture et de réglage de débit du produit, réalisé en un matériau élastique, mécaniquement déformable selon au moins deux directions, cet organe étant traversé par un passage de distribution du produit, un élément fixe et un élément mobile en translation par rapport à l'élément fixe, les éléments fixe et mobile définissant ledit passage, l'organe de fermeture étant pris en sandwich entre les éléments fixe et mobile, des moyens de commande pour provoquer le déplacement en translation de l'élément mobile vers l'élément fixe, ce déplacement entraínant une compression progressive de l'organe de fermeture de sorte que le passage est fermé progressivement par une déformation élastique dudit matériau. Thus, the subject of the present invention is a closure and adjustment capsule for flow rate of one or more non-compact products contained in a container, comprising a device for closing and adjusting the product flow, made in one elastic material, mechanically deformable in at least two directions, this member being traversed by a product distribution passage, a fixed element and an element movable in translation relative to the fixed element, the fixed elements and mobile defining said passage, the closure member being sandwiched between the fixed and mobile elements, control means to cause the translational movement of the movable element towards the fixed element, this displacement causing progressive compression of the closure member so that the passage is gradually closed by an elastic deformation of said material.

Selon l'invention, la fermeture est provoquée par un déplacement dudit matériau élastique, perpendiculairement à l'axe de la capsule, en réponse à un écrasement dudit matériau sous l'effet d'une force axiale exercée par l'élément mobile sur l'organe de fermeture.According to the invention, the closure is caused by a displacement of said material elastic, perpendicular to the axis of the capsule, in response to crushing of said material under the effect of an axial force exerted by the movable element on the closing member.

Avec la capsule de l'invention, il est possible d'ajuster le débit d'un ou plusieurs produits, selon les besoins de l'utilisateur et de la nature des produits (faible ou fort débit).With the capsule of the invention, it is possible to adjust the flow rate of one or more products, according to the needs of the user and the nature of the products (weak or strong debit).

Ainsi, selon un premier mode de réalisation conforme à l'invention, la capsule peut être montée sur un récipient contenant un seul produit. En tournant l'élément mobile, l'utilisateur peut faire varier la section du passage de distribution selon le débit souhaité de produit et selon la viscosité du produit. Cette disposition présente, en outre, l'avantage qu'une seule et même capsule de distribution peut être utilisée pour le conditionnement et la distribution de produits de viscosité très différente, car généralement, la distribution d'un produit de viscosité élevée nécessite une section du passage de distribution plus importante qu'un produit de viscosité faible. Ainsi on peut fabriquer industriellement un seul type de conditionnement quel que soit le produit qui sera conditionné.Thus, according to a first embodiment according to the invention, the capsule can be mounted on a container containing a single product. By turning the element mobile, the user can vary the section of the distribution passage according to the desired product flow rate and product viscosity. This provision presents, in addition, the advantage that a single dispensing capsule can be used for the packaging and distribution of products of very different viscosity, because generally, the distribution of a product of high viscosity requires a cross section of the passage of greater distribution than a product of low viscosity. So we can manufacture industrially only one type of packaging whatever the product to be packaged.

Selon un second mode de réalisation, la capsule peut servir à la distribution d'un bi-produit. Dans ce cas, la capsule comprend un canal central creux situé à l'intérieur du passage communiquant avec un premier produit, et définissant un espace communiquant avec un second produit, ces deux produits étant logés dans un même récipient, séparés par une cloison appropriée.According to a second embodiment, the capsule can be used for the distribution of a bi-product. In this case, the capsule includes a hollow central channel located inside of the passage communicating with a first product, and defining a space communicating with a second product, these two products being housed in a same container, separated by a suitable partition.

Un tel bi-produit est, par exemple un dentifrice à deux composantes ou bien tout autre produit à deux composantes nécessitant le stockage séparé des composantes, ces composantes devant être distribuées simultanément lors de l'utilisation du produit.Such a bi-product is, for example a two-component toothpaste or else other two-component product requiring separate storage of components, these components having to be distributed simultaneously during the use of the product.

Aussi, la première composante peut être une émulsion dermatologique de base et la seconde un concentré de filtres solaires. Selon l'invention, lors de la distribution de ce bi-produit, l'utilisateur peut faire varier le rapport volumique émulsion de base/concentré de filtres, de façon à obtenir, une composition antisolaire d'une teneur en filtres solaires variable. Ainsi, l'indice de protection peut être réglé à volonté par l'utilisateur.Also, the first component can be a basic dermatological emulsion and the second a concentrate of sun filters. According to the invention, during the distribution of this bi-product, the user can vary the emulsion volume ratio from base / concentrate of filters, so as to obtain a sunscreen composition of variable sunscreen content. Thus, the protection index can be set to will by the user.

Selon ce deuxième mode de réalisation, le canal, les éléments fixe et mobile ont, de préférence, une section circulaire et définissent un espace annulaire entourant le canal central. Ainsi, l'organe de fermeture est agencé de façon à pouvoir diminuer, voire obturer ledit espace, lors de sa compression, puis déformation radiale. Dans ces conditions, le canal central est en communication permanente avec la première composante du produit dont le débit est constant. L'espace annulaire est alimenté par la seconde composante du produit dont le débit est variable. On pourrait aussi envisager un organe de fermeture obturant successivement l'espace annulaire et le canal central. According to this second embodiment, the channel, the fixed and mobile elements have, preferably a circular section and define an annular space surrounding the central channel. Thus, the closure member is arranged so as to be able to decrease, or even close off said space, during its compression, then radial deformation. In these conditions, the central channel is in permanent communication with the first component of the product whose flow is constant. The annular space is supplied by the second component of the product, the flow of which is variable. We could also consider a closure member successively closing the annular space and the central channel.

Afin de faciliter le réglage de débit, on peut prévoir, sur la capsule des moyens d'indexation du débit du second produit, situés sur les éléments fixe et mobile respectivement. Par exemple, dans le cas de la composition antisolaire précitée, les moyens d'indexation peuvent indiquer l'indice de protection correspondant à la proportion volumique des deux composantes distribuées.In order to facilitate the adjustment of the flow rate, means can be provided on the capsule. for indexing the flow rate of the second product, located on the fixed and mobile elements respectively. For example, in the case of the abovementioned sunscreen composition, the indexing means may indicate the protection index corresponding to the volume proportion of the two distributed components.

Lorsque la section des éléments fixe et mobile, ainsi que celle de l'organe de fermeture sont circulaires, l'élément fixe comporte, avantageusement, un filetage coopérant avec un filetage complémentaire ménagé sur l'élément mobile, la rotation de l'élément mobile par rapport à l'élément fixe provoquant la compression de l'organe élastique, cet ensemble constituant les moyens de commande. Bien entendu, d'autres moyens de fixation complémentaire variable des éléments fixe et mobile pour assurer leur maintien dans une position déterminée peuvent être envisagés comme un système à crans.When the section of the fixed and mobile elements, as well as that of the closure are circular, the fixed element advantageously includes a thread cooperating with a complementary thread formed on the movable element, the rotation of the movable element relative to the fixed element causing the compression of the elastic member, this assembly constituting the control means. Good understood, other means of variable complementary fixing of the fixed elements and mobile to ensure their maintenance in a determined position can be envisioned as a notch system.

L'élément mobile en rotation est avantageusement une bague cylindrique comportant un bord de compression coopérant avec l'organe élastique.The movable element in rotation is advantageously a cylindrical ring having a compression edge cooperating with the elastic member.

Le matériau élastique peut être n'importe quel matériau susceptible de transformer une déformation en compression en une déformation radiale.The elastic material can be any material capable of transforming a compression deformation into a radial deformation.

Avantageusement, le matériau élastique est un matériau élastomérique choisi dans le groupe des élastomères de polyéthylène, de polyuréthane, de polyester ; des polyéther bloc amides ; des polyvinyles ; des ter-polymères d'éthylène, de propylène et d'un diène (EPDM) ; des polymères de styrène-butadiène séquencés (SEBS-SIS), les silicones, les caoutchoucs naturels ou synthétiques, par exemple du caoutchouc de nitrile ou de polybutadiène.Advantageously, the elastic material is an elastomeric material chosen from the group of polyethylene, polyurethane and polyester elastomers; of polyether block amides; polyvinyls; terpolymers of ethylene, propylene and a diene (EPDM); block styrene-butadiene polymers (SEBS-SIS), silicones, natural or synthetic rubbers, for example nitrile or polybutadiene rubber.

Le cas échéant, ce matériau élastomérique peut se présenter sous forme de mousse à cellules fermées.Where appropriate, this elastomeric material may be in the form of closed cell foam.

Le matériau élastique présente avantageusement une dureté Shore A comprise notamment dans la gamme allant de 20 à 80, et de préférence une dureté Shore A d'environ 30.The elastic material advantageously has a Shore A hardness included especially in the range from 20 to 80, and preferably Shore A hardness about 30.

L'organe de fermeture constitué de ce matériau élastique se présente, avantageusement, sous forme de rondelle pourvu d'un alésage central. L'alésage central de cette rondelle fait partie intégrante du passage de distribution.The closure member made of this elastic material is present, advantageously, in the form of a washer provided with a central bore. Bore center of this washer is an integral part of the distribution passage.

Cette rondelle peut présenter un diamètre externe et l'orifice constituant le canal de distribution présente un diamètre interne, tels que le rapport diamètre externe/diamètre interne sont, de préférence, d'environ 4. Avantageusement, la rondelle présente une épaisseur telle que le rapport diamètre interne/épaisseur est d'environ 1. This washer may have an external diameter and the orifice constituting the channel of distribution has an internal diameter, such as the external diameter / diameter ratio internal are preferably about 4. Advantageously, the washer has a thickness such that the internal diameter / thickness ratio is approximately 1.

    • En référence aux figures 1 à 3, on peut voir un premier mode de réalisation d'une capsule conforme à l'invention, désignée dans son ensemble par la référence 1.Referring to Figures 1 to 3, we can see a first embodiment of a capsule according to the invention, generally designated by the reference 1.

    Sur ces figures on a représenté, un récipient 2, en matériau souple ou semi-rigide, comportant un corps cylindrique fermé par une capsule de fermeture 1 et présentant un axe longitudinal X. Ce corps se termine par un épaulement 22 tronconique, raccordé un col cylindrique 8 de plus petit diamètre que celui du corps du récipient. Le col 8 constitue un élément fixe. Ce col 8 est muni d'un filetage extérieur 14. Le col 8 définit un passage interne central 12 par lequel un produit de consistance liquide, contenu dans le récipient, peut s'écouler. Entre le filetage 14 et l'épaulement 22 est disposé un cordon annulaire d'accrochage 20 dont le rôle sera décrit plus loin.In these figures, a container 2 is shown, of flexible or semi-rigid material, comprising a cylindrical body closed by a closure cap 1 and having a longitudinal axis X. This body ends in a frustoconical shoulder 22, connected a cylindrical neck 8 of smaller diameter than that of the container body. The neck 8 constitutes a fixed element. This neck 8 is provided with an external thread 14. The col 8 defines a central internal passage 12 through which a consistency product liquid in the container may leak. Between thread 14 and shoulder 22 is arranged an annular attachment cord 20 whose role will be described more far.

    La capsule de fermeture 1 comprend une rondelle 4 en matériau élastique déformable radialement et axialement. Sur la figure 4, cette rondelle est représentée dans sa forme initiale. Cette rondelle est disposée sur l'extrémité libre 9 du col 8. Elle est réalisée, par exemple, en caoutchouc de polybutadiène. Cette rondelle a sensiblement la même section que le col 8. Elle comporte un alésage central de distribution 6 obturable, faisant partie du passage central 12. Le diamètre de cet alésage est noté d. Le diamètre externe D de la rondelle 4 est tel que le rapport D/d soit d'environ 4. A titre d'exemple, D vaut 20 mm, d vaut 5 mm et l'épaisseur e de la rondelle est de 5 mm environ. Dans l'exemple considéré, le récipient 2 a un volume d'environ 250 ml et contient, par exemple, un shampooing capillaire. The closure cap 1 comprises a washer 4 of elastic material which can be deformed radially and axially. In Figure 4, this washer is shown in its initial form. This washer is disposed on the free end 9 of the neck 8. It is made, for example, of polybutadiene rubber. This washer has substantially the same section as the neck 8. It has a closable central distribution bore 6, forming part of the central passage 12. The diameter of this bore is noted d. The external diameter D of the washer 4 is such that the ratio D / d is approximately 4. For example, D is 20 mm, d is 5 mm and the thickness e of the washer is approximately 5 mm . In the example considered, the container 2 has a volume of approximately 250 ml and contains, for example, a hair shampoo.

    La capsule 1 comprend, de plus, un élément mobile 10, sous forme de bague cylindrique de réglage de débit, dont le sommet 11 constitue un plateau annulaire. Ce plateau 11 présente une ouverture centrale 13 qui constitue l'orifice de distribution du produit. La rondelle 4 est prise en sandwich entre le plateau annulaire 11 et l'extrémité 9 du col 8. La bague cylindrique 10 comporte un filetage intérieur 16 (voir figures 2 et 3), complémentaire du filetage extérieur 14 du col 8. Un bourrelet annulaire interne 18 est prévu sur le bord inférieur de la bague 10, du côté tourné vers le récipient ; il est destiné à s'encliqueter sous le cordon annulaire 20. Le cordon 20 est situé sur le col à une distance d' de l'épaulement 22 afin de permettre un déplacement axial de la bague 10 pour la compression ou la décompression de la rondelle 4. De plus, grâce à la présence de l'ensemble bourrelet 18 - cordon 20, la bague 10 ne peut pas être dévissée accidentellement, lors de l'utilisation. Le cordon 20 constitue un limitateur de dévissage.The capsule 1 further comprises a movable element 10, in the form of a cylindrical flow-adjusting ring, the top 11 of which constitutes an annular plate. This plate 11 has a central opening 13 which constitutes the product dispensing orifice. The washer 4 is sandwiched between the annular plate 11 and the end 9 of the neck 8. The cylindrical ring 10 has an internal thread 16 (see FIGS. 2 and 3), complementary to the external thread 14 of the neck 8. An annular bead internal 18 is provided on the lower edge of the ring 10, on the side facing the container; it is intended to snap under the annular bead 20. The bead 20 is located on the neck away from the shoulder 22 to allow axial displacement of the ring 10 for compression or decompression of the washer 4. In addition, thanks to the presence of the bead assembly 18 - cord 20, the ring 10 cannot be unscrewed accidentally, during use. The cord 20 constitutes a loosening limiter.

    Le fonctionnement de la capsule 1 est le suivant :
    Pendant le stockage, la capsule se trouve dans la position montrée sur la figure 2 : La bague 10 est vissée à fond écrasant axialement la rondelle 4 de sorte que l'alésage 6 est complètement fermé et la distribution du produit est impossible. Lorsque l'utilisateur dévisse la bague 10 par rotation, comme indiqué par la flèche F, celle-ci, s'éloigne de sa position initiale. En fin de dévissage, la capsule se trouve dans la position représentée sur la figure 3. Sur cette figure, on voit que la rondelle élastique 4 a retrouvé sa forme d'origine (voir figure 1) et que l'alésage 6 est ouvert. En retournant le récipient, le produit peut alors être distribué.    The operation of the capsule 1 is as follows:
    During storage, the capsule is in the position shown in FIG. 2: The ring 10 is screwed to the bottom, axially crushing the washer 4 so that the bore 6 is completely closed and the distribution of the product is impossible. When the user unscrews the ring 10 by rotation, as indicated by the arrow F, the latter moves away from its initial position. At the end of unscrewing, the capsule is in the position shown in Figure 3. In this figure, we see that the elastic washer 4 has returned to its original shape (see Figure 1) and that the bore 6 is open. By inverting the container, the product can then be dispensed.

    Il est possible d'ouvrir l'alésage canal 6 d'un degré moindre, en ne devisant la bague 10 que partiellement. Ainsi l'utilisateur peut mieux doser le débit de produit, ce qui est avantageux, notamment, lorsque le produit a une viscosité faible, comme un shampooing ou une lotion capillaire.It is possible to open the bore channel 6 by a lesser degree, by not twisting the ring 10 only partially. So the user can better dose the product flow, which is advantageous, in particular, when the product has a low viscosity, such as shampoo or hair lotion.

    Les figures 4 à 6 montrent un second mode de réalisation d'une capsule 101 utilisable pour distribuer un produit bi-composant. Sur ces figures, les éléments semblables à ceux des figures 1 à 3 ou jouant un rôle analogue, portent les numéros de référence des figures 1 à 3 majorés de 100. Leur description ne sera reprise que partiellement.Figures 4 to 6 show a second embodiment of a capsule 101 usable to distribute a two-component product. In these figures, the elements similar to those of FIGS. 1 to 3 or playing a similar role, bear the reference numbers of figures 1 to 3 increased by 100. Their description will not be recovery only partially.

    On voit sur les figures 4 et 5, un récipient 102 muni d'un col 108 et contenant deux composantes A et B de consistance pâteuse, par exemple une pâte dentifrice. Les composantes A et B sont superposées de sorte que la composante B se trouve à proximité du col 108. La composante A est donc placée entre la composante B et le fond du récipient. Du fait de leur viscosité élevée, les composantes A et B ne se mélangent pas. La capsule 101 montée sur le récipient 102 est conçue de sorte que le débit de distribution de la composante B soit variable.We see in Figures 4 and 5, a container 102 with a neck 108 and containing two components A and B of pasty consistency, for example a toothpaste. The components A and B are superimposed so that component B is at near the neck 108. The component A is therefore placed between the component B and the bottom of container. Due to their high viscosity, components A and B do not not mix. The capsule 101 mounted on the container 102 is designed so that the delivery rate of component B is variable.

    A cet effet est disposée à l'intérieur du col 108 une tubulure 117 de diamètre nettement inférieur à celui du col 108 et constitue un canal central 106a. La tubulure 117 dépasse légèrement du col 108 du récipient et s'étend vers l'intérieur de celui-ci, jusqu'à un niveau situé juste en dessous de l'interface AB. La tubulure 117 est calée dans le col 108 par une pluralité d'ailettes radiales 112 définissant un espace annulaire 118 rempli de la composante B.For this purpose is arranged inside the neck 108 a tube 117 of diameter significantly lower than that of the neck 108 and constitutes a central channel 106a. The tubing 117 slightly protrudes from the neck 108 of the container and extends towards the inside thereof, up to a level just below the AB interface. Tubing 117 is wedged in the neck 108 by a plurality of radial fins 112 defining a space ring 118 filled with component B.

    De façon analogue au premier mode de réalisation décrit ci-dessus, la capsule 101 comprend une rondelle 104 en matériau déformable disposée sur le col 108 du récipient et maintenue en place par une bague de réglage de débit 110. Cette bague 110 a une construction semblable à celle du premier mode de réalisation, à la différence près que l'orifice 113 de distribution comporte une jupe 115 s'étendant vers l'extérieur et entourant l'extrémité libre 117a de la tubulure 117. Selon un mode d'exécution particulier de la rondelle 104, comme représenté sur la figure 6, le canal de distribution 106a est muni de 4 échancrures radiales 106b régulièrement espacées.Analogously to the first embodiment described above, the capsule 101 comprises a washer 104 made of deformable material placed on the neck 108 of the container and held in place by a flow control ring 110. This ring 110 has a construction similar to that of the first embodiment, with the difference is that the dispensing orifice 113 has a skirt 115 extending outward and surrounding the free end 117a of the tube 117. According to one embodiment particular execution of the washer 104, as shown in Figure 6, the channel distribution 106a is fitted with 4 radial notches 106b regularly spaced.

    Le fonctionnement de ce mode de réalisation de capsule 101 est illustré sur la figure 5. Par vissage partiel de la bague 110, la rondelle 104 se trouve dans un état partiellement comprimé. Ainsi, ses bords internes 106c sont en contact avec la tubulure 117 et seules les échancrures 106b forment des passages pour la composante B. En outre, le canal central 106a est en communication avec la composante A. En comprimant le récipient 102, un cordon C de produit sort de l'orifice 113, comme illustré sur la figure 5. Ce cordon C est constitué essentiellement de la composante A et comporte quatre stries longitudinales externes formées par la composante B. En regardant la figure 5, on comprend que la profondeur des stries B puisse être variée en fonction du taux de compression de la rondelle 104. Ainsi, le rapport de débit composante A/composante B peut être réglé à volonté.The operation of this embodiment of capsule 101 is illustrated in the figure 5. By partial screwing of the ring 110, the washer 104 is in a state partially compressed. Thus, its internal edges 106c are in contact with the tubing 117 and only the notches 106b form passages for the component B. In addition, the central channel 106a is in communication with the component A. By compressing the container 102, a cord C of product comes out of the orifice 113, as illustrated in FIG. 5. This cord C is made up essentially of component A and has four longitudinal ridges external components formed by component B. Looking at Figure 5, we understand that the depth of the streaks B can be varied as a function of the compression ratio of the washer 104. Thus, the component A / component B flow ratio can be settled at will.

    Comme visible sur cette figure 5, des repères d'indexation 124, 126 du rapport de débit des composantes A et B, sont prévus respectivement sur le col 122 du récipient et sur la bague 110.As can be seen in this FIG. 5, indexing marks 124, 126 of the ratio of flow of components A and B, are provided respectively on the neck 122 of the container and on the ring 110.
