Description

La présente invention a pour objet un dispositif de conditionnement et de distribution d'un mélange de deux produits isolés l'un de l'autre avant l'opération de distribution selon le préambule de la revendication 1.The present invention relates to a device for packaging and dispensing a mixture of two products isolated from each other before the dispensing operation according to the preamble of claim 1.

On a déjà proposé de nombreux dispositifs permettant de conditionner isolément deux produits que l'on désire mélanger avant l'emploi ; on peut citer, par exemple, les dispositifs décrits dans FR-A-2 342 914, FR-A-2 370 650 ou FR-A-2 599 006 : ces dispositifs comprennent un récipient dont le goulot est obturé par un bouchon sur la face intérieure duquel est assujettie temporairement, pendant le stockage, une capsule éjectable délimitant avec le bouchon un premier compartiment, le corps du récipient constituant le second compartiment ; l'éjection de la capsule est obtenue par rotation du bouchon, ladite capsule tombant alors dans le fond du récipient en libérant le produit qu'elle contient ; de tels dispositifs, s'ils sont simples, présentent des inconvénients : d'une part, le volume du compartiment délimité par la capsule est limité par construction, en particulier dans le cas du récipient selon FR-A-2 342 914 où le diamètre et la hauteur de la capsule correspondent au diamètre et à la hauteur du goulot et, d'autre part, la capsule éjectée dans le récipient et non maintenue rend plus difficile la réalisation du mélange lorsque l'on secoue le récipient. Le brevet français 2 342 914 a servi de base au préambule de la revendication 1.Numerous devices have already been proposed making it possible to package two products in isolation that one wishes to mix before use; we can cite, for example, the devices described in FR-A-2 342 914, FR-A-2 370 650 or FR-A-2 599 006: these devices comprise a container whose neck is closed by a plug on the inner face of which is temporarily subjected, during storage, an ejectable capsule delimiting with the cap a first compartment, the body of the container constituting the second compartment; the capsule is ejected by rotating the cap, said capsule then falling into the bottom of the container, releasing the product it contains; such devices, if they are simple, have drawbacks: on the one hand, the volume of the compartment delimited by the capsule is limited by construction, in particular in the case of the container according to FR-A-2 342 914 where the diameter and the height of the capsule corresponds to the diameter and the height of the neck and, on the other hand, the capsule ejected into the container and not maintained makes it more difficult to produce the mixture when the container is shaken. French patent 2,342,914 formed the basis for the preamble of claim 1.

FR-A-2 599 006 concerne un dispositif qui comporte deux récipients séparés par une capsule, dans lequel les deux récipients sont mobiles en translation et en rotation, l'éjection de la capsule étant obtenue grâce à la translation vers le haut de la pièce contenant la capsule.FR-A-2 599 006 relates to a device which comprises two receptacles separated by a capsule, in which the two receptacles are movable in translation and in rotation, the ejection of the capsule being obtained by means of the upward translation of the part containing the capsule.

En outre, ces dispositifs, ainsi que les autres connus jusqu'ici, conviennent mal lorsque l'un des produits est un liquide oxydant et l'autre une crème, comme c'est le cas en cosmétique dans le domaine des colorations pour cheveux : le colorant est une crème très visqueuse et son mélange intime et homogène avec le liquide oxydant, juste avant utilisation, nécessite d'ouvrir un passage qui ne soit pas ensuite gêné par la présence d'un bouchon (ou autre pièce) retiré(e) de l'un des compartiments ou récipients pour assurer l'ouverture dudit passage. Outre les difficultés qu'il y a à assurer une parfaite étanchéité de la fermeture d'un passage de grande dimension, les dispositifs connus sont en général en matière plastique ; or, il est préférable, comme on le sait, que le compartiment ou le récipient qui contient une crème colorante soit métallique, plus précisément en aluminium, pour des raisons de conservation.In addition, these devices, as well as the others known up to now, are ill-suited when one of the products is an oxidizing liquid and the other a cream, as is the case in cosmetics in the field of hair colorings: the dye is a very viscous cream and its intimate and homogeneous mixture with the oxidizing liquid, just before use, requires to open a passage which is not then hindered by the presence of a plug (or other part) removed from one of the compartments or containers to ensure the opening of said passage. In addition to the difficulties there are in ensuring perfect sealing of the closure of a large passage, the known devices are generally made of plastic; however, it is preferable, as we know, that the compartment or the container which contains a coloring cream is metallic, more precisely aluminum, for conservation reasons.

La présente invention a pour but de résoudre, de façon simple, les problèmes évoqués ci-dessus.The present invention aims to solve, in a simple way, the problems mentioned above.

Ainsi, selon l'invention, un dispositif de conditionnement et de distribution d'un mélange de deux produits isolés l'un de l'autre avant l'opération de distribution, un tel dispositif comportant deux récipients de révolution assemblés de telle sorte qu'ils peuvent tourner l'un par rapport à l'autre tout en n'étant pas déplaçables axialement l'un par rapport à l'autre, l'un des récipients dit récipient supérieur étant ouvert à une extrémité et portant à son autre extrémité des moyens de distribution, l'autre récipient dit récipient inférieur comportant un corps muni d'un fond et fermé par un couvercle, ledit couvercle du récipient inférieur constituant un fond pour le récipient supérieur lorsque les deux récipients sont assemblés, chacun des récipients contenant alors l'un des produits ainsi isolés l'un de l'autre, est caractérisé par le fait que le couvercle du récipient inférieur est métallique et comporte une bande de prédécoupe adaptée à être découpée par une opération d'arrachement effectuée grâce à un moyen d'arrachement solidaire du récipient supérieur, ladite opération d'arrachement étant produite lorsque le récipient supérieur et le récipient inférieur sont soumis à un mouvement de rotation relatif de l'un par rapport à l'autre.Thus, according to the invention, a device for packaging and distributing a mixture of two products isolated from each other before the dispensing operation, such a device comprising two revolution vessels assembled so that they can rotate relative to each other while not being axially movable relative to each other, one of the containers called upper container being open at one end and carrying at its other end dispensing means, the other container called the lower container comprising a body provided with a bottom and closed by a cover, said cover of the lower container constituting a bottom for the upper container when the two containers are assembled, each of the containers then containing the '' one of the products thus isolated from each other, is characterized in that the cover of the lower container is metallic and has a pre-cut strip adapted to be re cut by a tearing operation carried out by means of tearing means integral with the upper container, said tearing operation being produced when the upper container and the lower container are subjected to a relative rotational movement of one with respect to to the other.

Avantageusement, une bague intermédiaire est prévue pour l'assemblage des récipients supérieur et inférieur ; la bague est munie de moyens supérieurs et inférieurs d'assemblage axial et de moyens supérieurs et inférieurs d'étanchéité pour être assemblée de manière étanche respectivement avec le récipient supérieur et le récipient inférieur, ladite bague étant empêchée de tourner par rapport au récipient supérieur et libre de tourner par rapport au récipient inférieur ; de préférence, le moyen d'arrachement est porté par la bague.Advantageously, an intermediate ring is provided for assembling the upper and lower containers; the ring is provided with upper and lower means for axial assembly and with upper and lower sealing means for being tightly assembled respectively with the upper container and the lower container, said ring being prevented from rotating relative to the upper container and free to rotate relative to the lower container; preferably, the tearing means is carried by the ring.

Avantageusement, la bande de prédécoupe que comporte le couvercle du récipient inférieur porte à une de ses extrémités un anneau s'étendant dans un plan parallèle à un rayon du couvercle du récipient inférieur et faisant un angle avec le plan dudit couvercle, le moyen d'arrachement comportant un doigt qui s'étend de manière substantiellement orthogonale par rapport à l'axe commun des deux récipients supérieur et inférieur, l'anneau et le doigt étant disposés radialement et axialement en sorte que, pour au moins une position angulaire relative des deux récipients, le doigt traverse l'anneau ; le doigt est porté par un support contre lequel l'anneau est susceptible de venir en butée lorsque les deux récipients sont tournés l'un par rapport à l'autre.Advantageously, the precut strip that the lid of the lower container comprises includes at one of its ends a ring extending in a plane parallel to a radius of the lid of the lower container and making an angle with the plane of said lid, the means pull-out comprising a finger which extends substantially orthogonal to the common axis of the two upper and lower containers, the ring and the finger being arranged radially and axially so that, for at least one relative angular position of the two receptacles, the finger crosses the ring; the finger is carried by a support against which the ring is capable of abutting when the two containers are turned relative to each other.

De préférence, le corps du récipient inférieur est métallique, et le couvercle et le corps du récipient inférieur sont assemblés par sertissage.Preferably, the body of the lower container is metallic, and the cover and the body of the lower container are assembled by crimping.

Selon une forme de réalisation, les moyens de distribution portés par le récipient supérieur sont prévus sur un bouchon monté sur un goulot que présente le récipient supérieur et sont munis d'un obturateur ; en variante, les moyens de distribution portés par le récipient supérieur sont ménagés dans une extrémité effilée et fermée du récipient supérieur, ladite extrémité effilée se terminant par un embout cassable facilement.According to one embodiment, the distribution means carried by the upper container are provided on a plug mounted on a neck that the upper container has and are provided with a shutter; alternatively, the dispensing means carried by the upper container are formed in a tapered and closed end of the upper container, said tapered end ending in an easily breakable tip.

Un tel dispositif convient bien lorsque le produit contenu dans le récipient supérieur est un liquide et le produit contenu dans le récipient inférieur est une pâte.Such a device is well suited when the product contained in the upper container is a liquid and the product contained in the lower container is a paste.

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

Sur ces dessins :

  • la figure 1 est une vue en élévation, partiellement en coupe, d'un dispositif selon la présente invention ;
  • la figure 2 est une vue partielle en coupe du dispositif de la figure 1, à plus grande échelle que celle de la figure 1, montrant l'assemblage des récipients supérieur et inférieur ;
  • la figure 3 est une vue partielle de dessus, par rapport à la figure 2, du dispositif sans le récipient supérieur ;
  • la figure 4 est une vue de dessus du récipient inférieur du dispositif des figures 1 à 3, à une échelle différente.
In these drawings:
  • Figure 1 is an elevational view, partially in section, of a device according to the present invention;
  • Figure 2 is a partial sectional view of the device of Figure 1, on a larger scale than that of Figure 1, showing the assembly of the upper and lower containers;
  • Figure 3 is a partial top view, with respect to Figure 2, of the device without the upper container;
  • Figure 4 is a top view of the lower container of the device of Figures 1 to 3, on a different scale.

En se reportant aux figures, on voit que le dispositif de conditionnement et de distribution selon l'invention comporte deux récipients, un récipient supérieur 1 et un récipient inférieur 2, de forme générale de révolution autour d'un axe commun.Referring to the figures, it can be seen that the packaging and distribution device according to the invention comprises two containers, an upper container 1 and a lower container 2, of general shape of revolution about a common axis.

A l'une de ses extrémités, le récipient supérieur 1 présente un goulot 11 recevant par vissage un bouchon 4 ; le bouchon 4 présente une extrémité tronconique 41 munie d'un passage axial 42, pour la distribution du mélange, d'un diamètre très inférieur à celui du goulot 11 ; le passage 42 peut être fermé par un obturateur 5 vissé sur l'extrémité tronconique 41 du bouchon 4 ; cette disposition permet d'adapter le diamètre des moyens de distribution que constitue le passage 42 à la distribution du mélange et le diamètre du goulot 11 au remplissage du récipient 1 ; bien entendu, cette extrémité supérieure du récipient 1 peut être réalisée autrement : par exemple, selon une variante non représentée, les moyens de distribution, portés par le récipient supérieur 1, peuvent être ménagés dans une extrémité effilée du récipient 1, ladite extrémité effilée se terminant par un embout venu de moulage avec le récipient 1, fermant ladite extrémité effilée, et cassable facilement.At one of its ends, the upper container 1 has a neck 11 receiving by screwing a plug 4; the plug 4 has a frustoconical end 41 provided with an axial passage 42, for the distribution of the mixture, of a diameter much smaller than that of the neck 11; the passage 42 can be closed by a shutter 5 screwed onto the frustoconical end 41 of the plug 4; this arrangement makes it possible to adapt the diameter of the distribution means that constitutes the passage 42 for the distribution of the mixture and the diameter of the neck 11 when the container 1 is filled; of course, this upper end of the container 1 can be produced in another way: for example, according to a variant not shown, the dispensing means, carried by the upper container 1, can be provided in a tapered end of the container 1, said tapered end is ending with an end piece molded with the container 1, closing said tapered end, and easily breakable.

A son extrémité opposée au goulot 11, le récipient supérieur 1 est ouvert au droit d'une collerette 12 d'extrémité ; à la surface extérieure de la collerette 12 d'extrémité est ménagée une gorge 13 annulaire.At its end opposite the neck 11, the upper container 1 is open in line with an end flange 12; an annular groove 13 is formed on the outer surface of the end flange 12.

Le récipient inférieur 2 est réalisé en aluminium ; il comprend un corps 27 muni d'un fond et un couvercle 21 ; le couvercle 21 est en forme de cuvette qui s'ajuste à l'intérieur du corps 27 et dont le bord 28 est rabattu par sertissage autour de l'extrémité du corps 27 pour assurer la fermeture de celui-ci : comme on le sait, une telle fermeture est d'une parfaite étanchéité ; bien entendu, elle est réalisée après que le récipient inférieur 2 ait été rempli de l'un des produits à mélanger avant distribution.The lower container 2 is made of aluminum; it comprises a body 27 provided with a bottom and a cover 21; the cover 21 is in the form of a bowl which adjusts inside the body 27 and the edge 28 of which is folded down by crimping around the end of the body 27 to ensure the closure thereof: as we know, such a closure is perfectly sealed; of course, it is carried out after the lower container 2 has been filled with one of the products to be mixed before distribution.

Le couvercle 21 du récipient inférieur 2 comporte une bande 22 de prédécoupe, visible sur la figure 4 ; la bande 22 s'étend circulairement autour de l'axe du récipient inférieur 2 selon un angle inférieur à 360 degrés ; à l'une de ses extrémités, la bande 22 est solidaire, par exemple au moyen d'un rivet 24, d'un organe d'ouverture 23 se terminant en un anneau 26 ; l'organe d'ouverture 23, donc l'anneau 26, s'étend dans un plan parallèle à un rayon du couvercle 21, ledit plan faisant un angle avec le plan dudit couvercle 21.The cover 21 of the lower container 2 has a precut strip 22, visible in FIG. 4; the strip 22 extends circularly around the axis of the lower container 2 at an angle less than 360 degrees; at one of its ends, the strip 22 is secured, for example by means of a rivet 24, to an opening member 23 ending in a ring 26; the opening member 23, therefore the ring 26, extends in a plane parallel to a radius of the cover 21, said plane making an angle with the plane of said cover 21.

Le récipient supérieur 1 et le récipient inférieur 2 sont assemblés par l'intermédiaire d'une bague 3.The upper container 1 and the lower container 2 are assembled by means of a ring 3.

La bague 3, de forme générale annulaire, présente une gorge supérieure 39A également annulaire et une gorge annulaire inférieure 39B ; les gorges 39A et 39B sont placées radialement à l'intérieur par rapport à la bague 3 ; avantageusement, la gorge 39B est axialement dans le prolongement d'une paroi supérieure cylindrique 38 qui borde la gorge 39A.The ring 3, of generally annular shape, has an upper annular groove 39A also annular and a lower annular groove 39B; the grooves 39A and 39B are placed radially inside with respect to the ring 3; advantageously, the groove 39B is axially in the extension of a cylindrical upper wall 38 which borders the groove 39A.

La gorge supérieure 39A définit une jupe d'étanchéité 31 dont la paroi 33 qui borde la gorge 39A est avantageusement conique ; pour l'assemblage de la bague 3 et du récipient supérieur 1, la collerette 12 du récipient supérieur 1 est introduite dans la gorge 39A de la bague 3 ; un effort de compression axiale applique la collerette 12 sur la paroi conique 33 de la jupe d'étanchéité 31 et assure une parfaite étanchéité de l'assemblage : l'effort de compression est maintenu grâce à un ergot annulaire 32 que présente la bague 3, lequel ergot annulaire 32 vient s'encliqueter dans la gorge annulaire 13 du récipient supérieur 1. On voit que cet assemblage bloque axialement la bague 3 par rapport au récipient supérieur 1 ; de plus, la bague 3 est également empêchée de tourner par rapport au récipient supérieur 1 : à cet effet, un dispositif anti-rotation 15 (figure 1) est prévu ; il consiste, par exemple, en un taquet s'étendant axialement, en prolongement de la paroi de la bague 3, vers la collerette 12 du récipient supérieur 1, ladite collerette 12 présentant une échancrure pour recevoir ledit taquet.The upper groove 39A defines a sealing skirt 31 whose wall 33 which borders the groove 39A is advantageously conical; for the assembly of the ring 3 and the upper container 1, the flange 12 of the upper container 1 is introduced into the groove 39A of the ring 3; an axial compression force applies the flange 12 to the conical wall 33 of the sealing skirt 31 and ensures perfect sealing of the assembly: the compression force is maintained thanks to an annular lug 32 presented by the ring 3, which annular lug 32 snaps into the annular groove 13 of the upper container 1. It can be seen that this assembly axially blocks the ring 3 relative to the upper container 1; in addition, the ring 3 is also prevented from rotating relative to the upper container 1: for this purpose, an anti-rotation device 15 (FIG. 1) is provided; it consists, for example, in a stop extending axially, in extension of the wall of the ring 3, towards the flange 12 of the upper container 1, said flange 12 having a notch for receiving said stop.

La gorge inférieure 39B définit également une jupe d'étanchéité 35 ; l'assemblage de la bague 3 et du récipient inférieur 2 est réalisée de manière analogue : le rebord axial du couvercle 21 est introduit dans la gorge 39B et l'assemblage étanche est maintenu par un ergot annulaire 34 de la bague 3 qui vient s'encliqueter sur la bordure transversale du bord roulé 28 du couvercle 21 ; cet assemblage étanche permet toutefois au récipient inférieur 2 de tourner par rapport à la bague 3.The lower groove 39B also defines a sealing skirt 35; the assembly of the ring 3 and the lower container 2 is carried out in a similar manner: the axial rim of the cover 21 is introduced into the groove 39B and the sealed assembly is maintained by an annular lug 34 of the ring 3 which comes snap onto the transverse edge of the rolled edge 28 of the cover 21; however, this sealed assembly allows the lower container 2 to rotate relative to the ring 3.

La bague 3 est munie intérieurement d'un moyen d'arrachement ; un tel moyen d'arrachement est visible sur les figures 2 et 3 ; il comprend un support 36 s'étendant transversalement et portant un doigt 37 ; le doigt 37 s'étend de manière substantiellement orthogonale par rapport à l'axe commun des deux récipients supérieur 1 et inférieur 2, qui est aussi d'ailleurs l'axe de la bague 3 ; lorsque la bague 3 est assemblée au récipient inférieur 2, le doigt 37 de la bague 3 et l'anneau 26 du couvercle 21 du récipient inférieur 2 sont disposés, radialement et axialement, de telle sorte que, pour au moins une position angulaire relative des deux récipients supérieur 1 et inférieur 2, le doigt 37 traverse l'anneau 26 ; en ce qui concerne le support 36, l'anneau 26, entourant le doigt 37, est susceptible de venir en butée contre le support 36 lorsque la bague 3 et le récipient inférieur 2 sont tournés l'un par rapport à l'autre.The ring 3 is provided internally with a tearing means; such a means of removal is visible in the figures 2 and 3; it comprises a support 36 extending transversely and carrying a finger 37; the finger 37 extends substantially orthogonal to the common axis of the two upper 1 and lower 2 receptacles, which is also, moreover, the axis of the ring 3; when the ring 3 is assembled to the lower container 2, the finger 37 of the ring 3 and the ring 26 of the cover 21 of the lower container 2 are arranged, radially and axially, so that, for at least one relative angular position of the two upper 1 and lower 2 receptacles, the finger 37 passes through the ring 26; as regards the support 36, the ring 26, surrounding the finger 37, is capable of abutting against the support 36 when the ring 3 and the lower container 2 are turned relative to one another.

Le fonctionnement du dispositif selon l'invention est simple.The operation of the device according to the invention is simple.

Dans un premier temps, la bague 3 est assemblée, comme décrit ci-dessus, avec le récipient inférieur 2, équipé de son couvercle 21 serti, un produit, par exemple une crème colorante, ayant été introduit dans le récipient inférieur 2 avant sertissage de son couvercle 21 ; dans un deuxième temps, le récipient supérieur 1 est assemblé, comme décrit ci-dessus, avec la bague 3 ; le couvercle 21 du récipient inférieur 2 constituant, conjointement avec la bague 3, un fond pour le récipient supérieur 1, celui-ci peut être rempli d'un produit, par exemple un liquide oxydant, à travers le goulot 11 ; le bouchon 4 est alors vissé sur le goulot 11 ; l'ensemble peut alors être stocké, en attente d'utilisation.As a first step, the ring 3 is assembled, as described above, with the lower container 2, fitted with its crimped cover 21, a product, for example a coloring cream, having been introduced into the lower container 2 before crimping its cover 21; in a second step, the upper container 1 is assembled, as described above, with the ring 3; the cover 21 of the lower container 2 constituting, together with the ring 3, a bottom for the upper container 1, the latter can be filled with a product, for example an oxidizing liquid, through the neck 11; the plug 4 is then screwed onto the neck 11; the assembly can then be stored, awaiting use.

Pour utilisation de la crème colorante contenue dans le récipient inférieur 2, il est nécessaire d'assurer un mélange homogène de la crème colorante et du liquide oxydant que contient le récipient supérieur 1 ; pour cela, il suffit de tourner, l'un par rapport à l'autre, les récipients supérieur 1 et inférieur 2 ; la bague 3 étant solidaire du récipient 1, le doigt 37 pénètre dans l'anneau 26 et, le mouvement de rotation étant poursuivi, la bande 22 de prédécoupe est arrachée, ouvrant le récipient inférieur 2 à la manière d'une boîte de conserve. Il est à noter que la présence de la bande 22 arrachée favorise l'homogénéisation du mélange lors de l'agitation du dispositif, malgré la grande viscosité de la crème colorante, la bande 22 métallique cisaillant les produits. Il est à noter également que le déplacement relatif en rotation des deux récipients ne modifie en rien le volume intérieur des récipients, comme c'est le cas dans certains dispositifs antérieurs dont les récipients se déplacent également axialement, lors de leur rotation relative, en se rapprochant l'un de l'autre ; aucune surpression n'est donc générée dans le dispositif selon l'invention lors de sa mise en oeuvre, ce qui est un avantage supplémentaire.For use of the coloring cream contained in the lower container 2, it is necessary to ensure a homogeneous mixture of the coloring cream and the oxidizing liquid that the upper container 1 contains; for this, it suffices to rotate, relative to one another, the upper 1 and lower 2 containers; the ring 3 being integral with the container 1, the finger 37 enters the ring 26 and, the rotational movement being continued, the pre-cut strip 22 is torn off, opening the lower container 2 in the manner of a can. It should be noted that the presence of the strip 22 torn off promotes the homogenization of the mixture during the stirring of the device, despite the high viscosity of the coloring cream, the metal strip 22 shearing products. It should also be noted that the relative displacement in rotation of the two containers does not in any way modify the interior volume of the containers, as is the case in certain prior devices whose containers also move axially, during their relative rotation, in bringing one closer to the other; no overpressure is therefore generated in the device according to the invention during its implementation, which is an additional advantage.

Le mélange ayant été effectué, sa distribution à travers le passage 42 peut dont être réalisée, l'obturateur 5 ayant été ôté.The mixing having been carried out, its distribution through the passage 42 can therefore be carried out, the shutter 5 having been removed.
