Abstract

The two separate components are contained in separate superposed containers (2,3) which can be rotated relative to each other in order to communicate. An obturator is moved upwards when the upper container is rotated relative to the lower container to cause mixing of the two components. The obturator has a plug (47) in its upper part with a sealing lip (48) which is engaged in a groove between the annular sealing lips (45,46) in upper end of a skirt (49) extending the plug.

Description

La présente invention concerne un dispositif pour le conditionnement séparé de deux composants à mélanger lors de la première utilisation et pour la distribution du mélange obtenu.The present invention relates to a device for separate packaging of two components to be mixed during first use and for the distribution of the mixture obtained.

L'invention concerne plus particulièrement un dispositif comportant deux contenants superposés aptes à communiquer entre eux par un passage et pouvant tourner l'un par rapport à l'autre autour d'un axe de rotation sans se déplacer axialement, un obturateur unique disposé dans ledit passage pour l'obturer pendant le stockage séparé des composants, l'un des contenants comportant en outre des moyens de guidage pour guider le déplacement de l'obturateur dans ledit passage et l'autre contenant comportant des moyens d'entraínement pour transformer la rotation relative des deux contenants en un déplacement axial de l'obturateur dans lesdits moyens de guidage, provoquant l'ouverture du passage et le mélange des composants.The invention relates more particularly to a device comprising two superimposed containers able to communicate with each other by a passage and being able to turn relative to each other around an axis of rotation without moving axially, a shutter single disposed in said passage to close it during storage separated from the components, one of the containers further comprising guide means for guiding the movement of the shutter in said passage and the other container comprising means to transform the relative rotation of the two containers in axial displacement of the shutter in said guide means, causing the opening of the passage and mixing components.

Ce type de dispositif permet d'effectuer le mélange des composants sans réduction de volume donc sans créer de surpression susceptible de projeter du mélange à l'ouverture.This type of device makes it possible to mix the components without volume reduction so without creating overpressure likely to spray mixture on opening.

On connaít par le modèle d'utilité japonais 2 503 369 un dispositif de ce type, dans lequel l'obturateur tombe dans le fond du contenant inférieur au terme de la rotation relative des deux contenants. L'obturateur peut venir se loger dans le passage si le dispositif est retourné, gênant ainsi la distribution du mélange, surtout si celui-ci est visqueux.We know by the Japanese utility model 2 503 369 a device of this type, in which the shutter falls into the bottom of the container less than the term of the relative rotation of the two containers. The shutter can be housed in the passage if the device is returned, thus hampering the distribution of the mixture, especially if it is viscous.

On connaít également, par la demande de brevet français 2 691 950, un dispositif à deux contenants comportant un obturateur mobile qui vient en appui, au terme de son déplacement, contre un épaulement d'un organe d'actionnement monté sur le contenant supérieur. Dans ce dispositif, l'inconvénient précité n'existe plus. Toutefois, l'obturateur s'étend sur pratiquement toute la hauteur du contenant supérieur et s'avère coûteux à produire si ce dernier est de grande dimension. La longueur relativement grande de l'obturateur entraíne de surcroít une torsion importante de celui-ci lors de l'actionnement, ce qui peut provoquer un blocage. En outre, l'obturateur est vissé à son extrémité inférieure sur une cheminée formant avec le contenant supérieur une gorge dans laquelle le composant contenu dans celui-ci peut être retenu sans se mélanger à l'autre composant.We also know, by the French patent application 2,691,950, a two-container device with a shutter mobile which comes to bear, at the end of its movement, against a shoulder of an actuator mounted on the container superior. In this device, the aforementioned drawback no longer exists. However, the shutter extends over almost the entire height of the larger container and is expensive to produce if the latter is large. The relatively large length of the shutter causes moreover a significant twist thereof during actuation, which can cause a blockage. In addition, the shutter is screwed at its lower end onto a chimney forming with the upper container a groove in which the component contained therein can be retained without mixing with the other component.

On connaít encore par le brevet allemand DE 44 36 863 C1 un dispositif à deux contenants de structure relativement complexe, comportant deux obturateurs qui s'écartent l'un de l'autre lors de la rotation relative des contenants.We also know from the German patent DE 44 36 863 C1 a device with two containers of relatively complex structure, comprising two shutters which deviate from each other during the relative rotation of containers.

La présente invention a pour objet un nouveau dispositif permettant de remédier à tout ou partie des inconvénients précités.The present invention relates to a new device allowing to remedy all or part of the aforementioned drawbacks.

Elle y parvient par le fait que l'obturateur comporte des moyens de retenue aptes à limiter son déplacement axial dans lesdits moyens de guidage au terme de la rotation relative desdits contenants.It does this by the fact that the shutter has retaining means able to limit its axial movement in said guide means at the end of the relative rotation of said containers.

Grâce à l'invention, l'obturateur est empêché de gêner l'écoulement du mélange lorsque ce dernier est distribué et son coût de réalisation est sensiblement indépendant de la dimension des contenants puisqu'il n'a pas à s'étendre sur toute la hauteur de l'un ou l'autre de ceux-ci. De plus, le problème de blocage précité lié à la torsion de l'obturateur ne se pose pas.Thanks to the invention, the shutter is prevented from obstructing the flow of the mixture when it is distributed and its cost is substantially independent of the size of the containers since it does not have to extend over the entire height of one either of these. In addition, the aforementioned blocking problem linked to the shutter does not twist.

Dans une mise en oeuvre particulière de l'invention, les moyens de guidage sont conformés pour guider l'obturateur en translation.In a particular implementation of the invention, the means guides are shaped to guide the shutter in translation.

Dans une réalisation particulière, ces moyens de guidage comportent un étranglement non symétrique de révolution formé dans le passage.In a particular embodiment, these guide means have a non-symmetrical throttle of revolution formed in the passage.

De préférence, l'obturateur comporte alors un fût conformé pour coopérer avec ces moyens de guidage et les moyens de retenue sont constitués par au moins un relief formant saillie à une extrémité de ce fût.Preferably, the shutter then comprises a barrel shaped to cooperate with these guide means and the retaining means are formed by at least one relief projecting at one end of it was.

Dans une autre réalisation particulière, l'obturateur comporte une jupe présentant des évidements conformés pour coopérer avec les moyens de guidage et les moyens de retenue sont constitués par la matière de la jupe à l'extrémité de ces évidements.In another particular embodiment, the shutter comprises a skirt having shaped recesses to cooperate with the guide means and the retaining means are constituted by the material of the skirt at the end of these recesses.

Dans une autre réalisation particulière, les moyens de guidage comportent des gorges conformées pour guider en coulissement des pattes de l'obturateur et les moyens de retenue sont constitués par une couronne reliant lesdites pattes.In another particular embodiment, the guide means have shaped grooves to guide the sliding of the shutter tabs and the retaining means are constituted by a crown connecting said legs.

Dans une mise en oeuvre particulière de l'invention, les moyens d'entraínement comportent au moins un filetage qui peut être, dans une réalisation particulière, formé sur une bague assujettie à l'un des contenants ou en variante, formé directement par moulage sur l'un des contenants.In a particular implementation of the invention, the means drive comprise at least one thread which can be, in a particular embodiment, formed on a ring subject to one containers or alternatively, formed directly by molding on one containers.

Dans une autre réalisation particulière, les moyens d'entraínement comportent une rampe hélicoïdale conformée pour appuyer progressivement sur l'obturateur lorsque les deux contenants sont entraínés en rotation l'un par rapport à l'autre.In another particular embodiment, the means drive have a helical ramp shaped to gradually press the shutter when the two containers are rotated relative to each other.

Dans une autre réalisation particulière, l'obturateur comporte un compartiment destiné à contenir un troisième composant et le dispositif comporte en outre dans le passage par lequel les deux contenants communiquent une paroi transversale ajourée conformée pour fermer ce compartiment lorsque l'obturateur est initialement en place dans le passage.In another particular embodiment, the shutter comprises a compartment intended to contain a third component and the device further comprises in the passage through which the two containers communicate a perforated transverse wall shaped to close this compartment when the shutter is initially in place in the passage.

Ce troisième composant est par exemple un parfum qui se mélange aux deux autres composants lors de la première utilisation du dispositif.This third component is for example a perfume which mixes to the other two components when using the device.

On a représenté sur les figures 1 et 2 un dispositif 1 conforme à un premier exemple de réalisation de l'invention.There is shown in Figures 1 and 2 a device 1 conforms to a first embodiment of the invention.

Ce dispositif 1 comporte un contenant inférieur 2 et un contenant supérieur 3 pouvant tourner l'un par rapport à l'autre autour d'un axe de rotation qui coïncide avec l'axe longitudinal X du dispositif.This device 1 comprises a lower container 2 and a upper container 3 which can rotate relative to each other around an axis of rotation which coincides with the longitudinal axis X of the device.

Le contenant inférieur 2 comporte à sa partie supérieure un col 4 muni d'un bourrelet annulaire 5 sur lequel s'encliquette une bague 6.The lower container 2 has at its upper part a neck 4 provided with an annular bead 5 on which a ring engages 6.

Le contenant supérieur 3 comporte à sa partie supérieure un col fileté 7 et il est partiellement engagé à sa partie inférieure 8 dans le col 4. The upper container 3 has at its upper part a neck threaded 7 and it is partially engaged at its lower part 8 in collar 4.

Un embout de distribution 9 comportant une extrémité sécable 10 est vissé sur le col 7.A dispensing nozzle 9 having a breakable end 10 is screwed onto the neck 7.

La partie inférieure 8 se raccorde au reste du contenant supérieur 3 en formant un étranglement 11 dont la section transversale est non symétrique de révolution autour de l'axe X.The lower part 8 is connected to the rest of the container upper 3 by forming a constriction 11 whose cross section transverse is non-symmetrical in revolution around the X axis.

Plus particulièrement, comme représenté sur la figure 3, l'étranglement 11 comporte deux avancées 12 diamétralement opposées.More particularly, as shown in FIG. 3, the throttle 11 has two diametrically opposite projections 12.

La bague 6 comporte une jupe extérieure 13 et deux jupes concentriques 14 et 15, lesquelles se raccordent par une paroi 18 en formant une gorge annulaire 16 ouverte vers le haut, dans laquelle est engagée la partie inférieure 8 du contenant supérieur 3.The ring 6 has an outer skirt 13 and two skirts concentric 14 and 15, which are connected by a wall 18 in forming an annular groove 16 open upwards, in which the lower part 8 of the upper container 3 is engaged.

La jupe intérieure 14 présente sur sa face radialement intérieure deux filetages 17 s'étendant chacun sur un peu moins d'un demi-tour autour de l'axe X et symétriques l'un de l'autre par rapport à cet axe.The inner skirt 14 has on its face radially inner two threads 17 each extending over a little less than a U-turn around the X axis and symmetrical to each other by relation to this axis.

Les filetages 17 constituent des moyens d'entraínement au sens de la présente invention, comme cela sera précisé plus loin.The threads 17 constitute drive means in the sense of the present invention, as will be explained later.

La paroi 18, qui constitue le fond de la gorge 16 précitée, est prolongée vers le bas par deux lèvres annulaires d'étanchéité 19 et 20 ménageant entre elles une gorge annulaire 21.The wall 18, which constitutes the bottom of the aforementioned groove 16, is extended downwards by two annular sealing lips 19 and 20 providing an annular groove 21 therebetween.

La jupe intermédiaire 15 se raccorde à la jupe extérieure 13 en formant une gorge annulaire 22 ouverte vers le bas et dans laquelle est engagé le col 4.The intermediate skirt 15 is connected to the outer skirt 13 in forming an annular groove 22 open downwards and in which Col 4 is engaged.

Des reliefs 23 surmontés d'évidements sont réalisés sur la paroi par laquelle la jupe intermédiaire 15 se raccorde à la jupe extérieure 13 pour s'encliqueter sur le bourrelet annulaire 5. Le cas échéant, les reliefs 23 peuvent aussi assurer le blocage en rotation de la bague 6 par rapport au contenant inférieur 2.Reliefs 23 surmounted by recesses are made on the wall through which the intermediate skirt 15 is connected to the skirt 13 to snap onto the annular bead 5. The case where appropriate, the reliefs 23 can also ensure the blocking in rotation of the ring 6 relative to the lower container 2.

La jupe intermédiaire 15 comporte en outre, à son extrémité supérieure et sur sa surface radialement intérieure, un bourrelet annulaire 24 qui retient par encliquetage des dents 25 formant saillie sur la surface radialement extérieure de la partie inférieure 8 du contenant supérieur 3.The intermediate skirt 15 further comprises, at its end upper and on its radially inner surface, a bead annular 24 which retains by snapping teeth 25 forming protrusion on the radially outer surface of the lower part 8 of the upper container 3.

Le contenant supérieur 3 vient en appui sur le bord supérieur de la jupe extérieure 13 de sorte qu'il peut tourner par rapport à celle-ci sans se déplacer axialement le long de l'axe X. The upper container 3 comes to bear on the upper edge of the outer skirt 13 so that it can rotate relative to without moving axially along the X axis.

Un obturateur 26 permet de séparer les composants contenus respectivement dans le contenant inférieur 2 et dans le contenant supérieur 3 jusqu'à la première utilisation du dispositif 1.A shutter 26 makes it possible to separate the components contained respectively in the lower container 2 and in the container upper 3 until the first use of the device 1.

Ces deux composants n'ont pas été représentés sur le dessin dans un souci de clarté.These two components have not been shown in the drawing for the sake of clarity.

Il peut s'agir de deux liquides ou d'un liquide et d'une poudre.It can be two liquids or a liquid and a powder.

L'un des composants est constitué par exemple par un oxydant et l'autre par un colorant, qui mélangé au premier forme une teinture capillaire.One of the components consists for example of an oxidant and the other by a dye, which mixed with the first forms a dye capillary.

Les contenants inférieur et supérieur sont réalisés dans des matériaux chimiquement compatibles avec ces composants. Le contenant supérieur peut par exemple être réalisé en polychlorure de vinyle, le contenant inférieur en polyéthylène et l'obturateur en polypropylène.The lower and upper containers are made in materials chemically compatible with these components. Container upper can for example be made of polyvinyl chloride, the lower polyethylene container and the shutter in polypropylene.

On a représenté isolément l'obturateur 26 sur les figures 4 à 7.Shutter 26 is shown in isolation in FIGS. 4 to 7.

L'obturateur 26 comporte un fût creux 27 muni, à mi-hauteur environ et sur sa surface radialement extérieure, de deux ergots 28 diamétralement opposés, conformés pour s'engager dans les filetages 17.The shutter 26 comprises a hollow barrel 27 provided, at mid-height approximately and on its radially outer surface, of two pins 28 diametrically opposed, shaped to engage in threads 17.

Le fût 27 comporte à sa partie supérieure et à sa partie inférieure des ajours 30 et 31 respectivement destinés à coopérer avec les avancées 12 et à permettre l'écoulement du composant contenu dans le contenant supérieur 3 vers le contenant inférieur 2 lors de la première utilisation du dispositif.The barrel 27 has at its upper part and at its part lower of the openings 30 and 31 respectively intended to cooperate with the advances 12 and to allow the flow of the contained component in the upper container 3 to the lower container 2 when the first use of the device.

Le fût 27 est muni en outre de nervures longitudinales 32 intérieures, situées le long des bords longitudinaux des ajours 30 et 31.The barrel 27 is further provided with longitudinal ribs 32 interior, located along the longitudinal edges of openings 30 and 31.

Ces nervures 32 sont munies à leur extrémité supérieure de dents 33 constituant des moyens de retenue au sens de la présente invention, aptes à venir en appui sur les bords supérieurs des avancées 12 de l'étranglement 11 pour empêcher l'obturateur 26 de tomber dans le contenant inférieur 2, comme cela sera précisé dans la suite.These ribs 32 are provided at their upper end with teeth 33 constituting retaining means within the meaning of this invention, capable of coming to bear on the upper edges of the 12 throttles 11 advanced to prevent the shutter 26 from fall into the lower container 2, as will be specified in the after.

Le fût 27 se raccorde à son extrémité inférieure à un bouchon 34 muni à sa périphérie d'une lèvre annulaire d'étanchéité 35 qui ménage avec le reste du bouchon une gorge annulaire 36. The barrel 27 is connected at its lower end to a plug 34 provided at its periphery with an annular sealing lip 35 which household with the rest of the cap an annular groove 36.

Lorsque l'obturateur 26 occupe sa position initiale dans le dispositif 1, la lèvre 35 vient s'engager dans la gorge 21 formée entre les lèvres 19 et 20.When the shutter 26 occupies its initial position in the device 1, the lip 35 engages in the groove 21 formed between lips 19 and 20.

L'assemblage du dispositif 1 s'effectue de la façon suivante.The assembly of the device 1 is carried out as follows.

L'obturateur 26 est vissé dans la jupe intérieure 14 jusqu'à ce que la lèvre 35 soit insérée dans la gorge 21.The shutter 26 is screwed into the inner skirt 14 until that the lip 35 is inserted into the groove 21.

Ensuite, le contenant supérieur 3 est positionné au-dessus de la bague 6, les avancées 12 étant orientées de manière à s'engager entre les nervures 32. Le contenant supérieur 3 est alors descendu jusqu'à s'encliqueter sur le bourrelet 24 de la jupe intermédiaire 15. Les dents 33 franchissent par déformation élastique les avancées 12. Le contenant supérieur 3 est rempli avec l'un des composants puis l'embout 9 est vissé sur celui-ci.Then, the upper container 3 is positioned above the ring 6, the projections 12 being oriented so as to engage between the ribs 32. The upper container 3 is then lowered until it clicks into place on the bead 24 of the intermediate skirt 15. The teeth 33 cross the projections by elastic deformation 12. The upper container 3 is filled with one of the components and then the tip 9 is screwed thereon.

Le contenant inférieur 2 est rempli avec l'autre composant, puis l'ensemble constitué par le contenant supérieur 3 et la bague 6 est encliqueté sur le col 4.The lower container 2 is filled with the other component, then the assembly constituted by the upper container 3 and the ring 6 is snapped onto the neck 4.

On notera que l'étanchéité entre la bague 6 et le contenant inférieur 2 est assurée par la jupe intermédiaire 15 qui vient s'appliquer de façon étanche par sa surface radialement extérieure sur la surface radialement intérieure du col 4 et que l'étanchéité entre la bague 6 et le contenant supérieur 3 est assurée par la jupe intérieure 14 qui vient s'appliquer par sa surface radialement extérieure sur la surface radialement intérieure de la partie inférieure 8.It will be noted that the seal between the ring 6 and the container lower 2 is provided by the intermediate skirt 15 which comes apply tightly by its radially outer surface on the radially inner surface of the neck 4 and that the seal between the ring 6 and the upper container 3 is provided by the skirt interior 14 which is applied by its radially surface outer on the radially inner surface of the part lower 8.

Pour mélanger les composants, l'utilisateur tourne le contenant supérieur 3 par rapport au contenant inférieur 2 et la bague 6.To mix the components, the user turns the container upper 3 relative to the lower container 2 and the ring 6.

L'obturateur 26 tourne avec le contenant supérieur 3 du fait de la coopération entre les avancées 12 et les nervures 32.The shutter 26 rotates with the upper container 3 due to cooperation between the projections 12 and the ribs 32.

L'obturateur 26 ainsi entraíné en rotation est déplacé vers le bas par les filetages 17, les nervures 32 coulissant sur les avancées 12 engagées dans les ajours 30.The shutter 26 thus rotated is moved towards the bottom by threads 17, ribs 32 sliding on the projections 12 engaged in openwork 30.

Le composant contenu dans le contenant supérieur 3 peut gagner le contenant inférieur 2 par l'intérieur du fût 27 et par les ajours 31.The component contained in the upper container 3 can win the lower container 2 through the inside of the barrel 27 and through the openings 31.

On remarquera que les avancées 12 constituent des moyens de guidage situés au niveau du passage par lequel les contenants inférieur 2 et supérieur 3 communiquent. It will be noted that the advances 12 constitute means of guide located at the passage through which the containers lower 2 and upper 3 communicate.

On remarquera également que l'obturateur présente un encombrement axial relativement faible par rapport au dispositif décrit dans la demande de brevet français antérieure 2 691 950 précitée.Note also that the shutter has a relatively small axial size compared to the device described in the previous French patent application 2,691,950 cited above.

On a représenté sur les figures 8 à 11 un dispositif 40 conforme à un deuxième exemple de réalisation de l'invention.FIGS. 8 to 11 show a device 40 according to a second embodiment of the invention.

Ce dispositif 40 comporte certains éléments constitutifs identiques à ceux de l'exemple de réalisation précédent, qui ne seront pas décrits à nouveau et auxquels on attribuera les mêmes références.This device 40 includes certain constituent elements identical to those of the previous embodiment, which does not will not be described again and assigned the same references.

Le dispositif 40 diffère du précédent essentiellement par la forme de l'obturateur, référencé 41, et par la forme de la jupe intérieure, référencée 43.The device 40 differs from the previous one essentially by the shape of the shutter, referenced 41, and by the shape of the skirt interior, referenced 43.

La bague encliquetée sur le contenant inférieur 2 est ici référencée 42.The ring snapped onto the lower container 2 is here referenced 42.

L'obturateur 41 est déplacé vers le haut lorsque le contenant supérieur 3 est entraíné en rotation par rapport au contenant inférieur 2 pour provoquer le mélange des composants.The shutter 41 is moved upward when the container upper 3 is rotated relative to the container lower 2 to cause the components to mix.

La jupe intérieure 43 comporte deux filetages 44 sur sa face radialement extérieure et deux lèvres annulaires d'étanchéité 45 et 46 concentriques à son extrémité supérieure.The inner skirt 43 has two threads 44 on its face radially outer and two annular sealing lips 45 and 46 concentric at its upper end.

Les filetages 44 sont symétriques l'un de l'autre par rapport à l'axe X et constituent des moyens d'entraínement au sens de la présente invention.The threads 44 are symmetrical to each other with respect to the X axis and constitute training means within the meaning of the present invention.

L'obturateur 41 comporte à sa partie supérieure un bouchon 47 pourvu d'une lèvre annulaire d'étanchéité 48, destinée à s'engager dans la gorge formée entre les lèvres 45 et 46, pendant le stockage séparé des composants.The shutter 41 has at its upper part a plug 47 provided with an annular sealing lip 48, intended to engage in the groove formed between the lips 45 and 46, during storage separate from components.

Le bouchon 47 est prolongé à sa périphérie vers le bas par une jupe 49 pourvue en deux emplacements diamétralement opposés sur sa surface radialement intérieure d'ergots 50 adaptés à venir en prise chacun dans un filetage 44.The plug 47 is extended at its periphery downwards by a skirt 49 provided in two diametrically opposite locations on its radially inner surface of lugs 50 adapted to engage each in a thread 44.

La jupe 49 présente deux évidements 51 diamétralement opposés dans lesquels s'engagent les avancées 12 du contenant supérieur 3.The skirt 49 has two diametrically opposite recesses 51 in which the advances 12 of the upper container 3 are engaged.

Ainsi, l'obturateur 41 est bloqué en rotation par rapport au contenant supérieur 3 tout en pouvant se déplacer axialement par rapport à celui-ci. Thus, the shutter 41 is locked in rotation relative to the upper container 3 while being able to move axially by compared to this one.

Les évidements 51 ne s'étendent pas jusqu'à l'extrémité inférieure de la jupe 49, de sorte que les régions 52 de la jupe 49 situées en dessous de ces évidements 51 limitent le déplacement axial de l'obturateur vers le haut et constituent des moyens de retenue au sens de la présente invention.The recesses 51 do not extend to the end bottom of skirt 49, so that regions 52 of skirt 49 located below these recesses 51 limit the axial displacement from the shutter upwards and constitute retaining means at the meaning of the present invention.

L'assemblage du dispositif 40 s'effectue en vissant l'obturateur 41 sur la jupe intérieure 43 jusqu'à obtenir un contact étanche entre les lèvres d'étanchéité 45, 46 et 48, puis le contenant supérieur 3 est encliqueté dans la bague 42.The device 40 is assembled by screwing the shutter 41 on the inner skirt 43 until contact is obtained tight between the sealing lips 45, 46 and 48, then the container upper 3 is snapped into the ring 42.

Après remplissage de celui-ci, l'embout 9 est mis en place puis l'ensemble est rapporté sur le contenant inférieur 2, lequel a été rempli au préalable.After filling it, the nozzle 9 is put in place and the assembly is attached to the lower container 2, which has been completed beforehand.

Pour provoquer le mélange des composants, l'utilisateur tourne le contenant supérieur 3 par rapport au contenant inférieur 2, ce qui provoque la rotation de l'obturateur 41 dans les filetages 44 et sa remontée, jusqu'à ce qu'il prenne la position représentée sur les figures 10 et 11, les régions 52 venant en butée sur les avancées 12.To cause the components to mix, the user turns the upper container 3 relative to the lower container 2, which causes the shutter 41 to rotate in the threads 44 and its ascent, until it takes the position shown on the Figures 10 and 11, the regions 52 abutting the projections 12.

Le composant contenu dans le contenant supérieur s'écoule alors par les évidements 51 dans le contenant inférieur 2.The component contained in the upper container then drains through the recesses 51 in the lower container 2.

On a représenté sur les figures 12 à 17 un dispositif 60 conforme à un troisième exemple de réalisation de l'invention.FIGS. 12 to 17 show a device 60 according to a third embodiment of the invention.

Ce dispositif 60 comporte un contenant inférieur 61 se présentant sous la forme d'un flacon pourvu d'un col 62. Le contenant supérieur 63 présente à sa partie supérieure un col fileté 64 obturé par un embout de distribution 65 pourvu d'une partie sécable 66.This device 60 comprises a lower container 61 in the form of a bottle with a neck 62. The container upper 63 has a closed threaded neck 64 at its upper part by a dispensing nozzle 65 provided with a breakable part 66.

Le contenant supérieur 63 comporte une partie inférieure 67 partiellement engagée dans le col 62 du contenant inférieur 61.The upper container 63 has a lower part 67 partially engaged in the neck 62 of the lower container 61.

Le col 62 est pourvu, au voisinage de son extrémité supérieure, d'un bourrelet annulaire 68 formant radialement saillie vers l'extérieur, sur lequel vient s'encliqueter une bague 69.The neck 62 is provided, in the vicinity of its upper end, of an annular bead 68 radially projecting towards the outside, on which a ring 69 is snapped on.

Cette dernière comporte une jupe extérieure 70 et une jupe intérieure 71 qui sont raccordées par une paroi 72 sensiblement tronconique, pourvue de reliefs 73 surmontés d'évidements, ces reliefs étant destinés à s'encliquer sur le bourrelet annulaire 68.The latter comprises an outer skirt 70 and a skirt interior 71 which are connected by a wall 72 substantially frustoconical, provided with reliefs 73 surmounted by recesses, these reliefs being intended to snap onto the annular bead 68.

La jupe intérieure 71 est engagée dans le col 62 et prend appui par un rebord annulaire 76 sur la tranche de celui-ci. The inner skirt 71 is engaged in the collar 62 and is supported by an annular rim 76 on the edge thereof.

La jupe intérieure 71 est munie en outre à son extrémité supérieure et sur sa surface radialement intérieure d'un bourrelet annulaire 74 sur lequel s'encliquettent des dents 75 réalisées sur la surface radialement extérieure de la partie inférieure 67 du contenant supérieur 63.The inner skirt 71 is further provided at its end upper and on its radially inner surface of a bead ring 74 onto which teeth 75 made on the radially outer surface of the lower part 67 of the upper container 63.

Le contenant supérieur 63 vient en appui sur la jupe extérieure 70 de sorte qu'il peut tourner par rapport au contenant inférieur sans se déplacer axialement.The upper container 63 comes to bear on the outer skirt 70 so that it can rotate relative to the lower container without moving axially.

Des crans 97 sont formés sous le bourrelet annulaire 74, pour coopérer avec les dents 75 et bloquer en rotation le contenant supérieur 63 et la bague 69.Notches 97 are formed under the annular bead 74, to cooperate with teeth 75 and block the container in rotation upper 63 and the ring 69.

La jupe intérieure 71 est fermée à sa partie inférieure par une paroi transversale 78, portant sur sa face supérieure une lèvre annulaire d'étanchéité 77 qui vient s'appliquer de façon étanche sur la surface radialement intérieure de la partie inférieure 67 du contenant supérieur 63.The inner skirt 71 is closed at its lower part by a transverse wall 78, carrying on its upper face a lip sealing ring 77 which is applied sealingly on the radially inner surface of the lower part 67 of the upper container 63.

Un décrochement 96, cylindrique de révolution autour de l'axe X, est formé au centre de la paroi 78 et des ajours 79 sont réalisés entre ce décrochement 96 et la lèvre 77.A recess 96, cylindrical of revolution around the axis X, is formed in the center of the wall 78 and openings 79 are made between this recess 96 and the lip 77.

Le col 62 comporte à sa base des portées 98 disposées de manière à former deux gorges 99 diamétralement opposées, comme représenté sur la figure 17.The neck 62 has at its base staves 98 arranged in so as to form two diametrically opposite grooves 99, as shown in figure 17.

Un obturateur 80 permet de séparer les composants respectivement contenus dans les contenants inférieur et supérieur avant la première utilisation du dispositif 60.A shutter 80 allows the components to be separated contained respectively in the lower and upper containers before the first use of the device 60.

On a représenté isolément sur la figure 16 cet obturateur 80.FIG. 16 shows this shutter 80 in isolation.

Celui-ci comporte un fût central 81, fermé à son extrémité inférieure 82, et pourvu à son extrémité supérieure d'une lèvre annulaire d'étanchéité 83 destinée à s'appliquer de façon étanche, lorsque l'obturateur 80 est dans sa position initiale, sur la périphérie du décrochement 96 pour former un compartiment étanche 84 apte à contenir un troisième composant, par exemple un parfum, stocké sans contact avec les deux autres composants.This comprises a central barrel 81, closed at its end lower 82, and provided at its upper end with a lip sealing ring 83 intended to be applied sealingly, when the shutter 80 is in its initial position, on the periphery of the step 96 to form a sealed compartment 84 able to contain a third component, for example a perfume, stored without contact with the other two components.

Le fût 81 est prolongé radialement vers l'extérieur, à la base de la lèvre annulaire d'étanchéité 83, par une paroi transversale 85 munie à sa périphérie et sur sa face supérieure d'une lèvre annulaire d'étanchéité 86, concentrique à la lèvre 83. The barrel 81 is extended radially outwards, at the base of the annular sealing lip 83, through a transverse wall 85 provided at its periphery and on its upper face with an annular lip seal 86, concentric to the lip 83.

L'obturateur 80 comporte à sa partie supérieure une couronne 87 de plus grand diamètre que la paroi transversale 85 et qui se raccorde à cette dernière par deux pattes de liaison 88 diamétralement opposées.The shutter 80 has at its upper part a crown 87 larger in diameter than the transverse wall 85 and which is connects to the latter by two connecting lugs 88 diametrically opposite.

Les pattes 88 ménagent chacune une gorge 89 avec la lèvre annulaire d'étanchéité 86.The legs 88 each provide a groove 89 with the lip sealing ring 86.

La jupe intérieure 71 comporte une lèvre annulaire d'étanchéité 90 qui vient s'appliquer sur la surface radialement intérieure de la lèvre 86 pour assurer l'étanchéité entre la bague 69 et l'obturateur 80.The inner skirt 71 has an annular sealing lip 90 which is applied to the radially inner surface of the lip 86 for sealing between the ring 69 and the shutter 80.

Le bord inférieur de la jupe intérieure 71 forme une rampe hélicoïdale 92 s'étendant sur un peu moins d'un demi-tour.The lower edge of the inner skirt 71 forms a ramp helical 92 extending a little less than half a turn.

Lorsque l'obturateur 80 est en place, la rampe 92 se situe hors des gorges 89.When the shutter 80 is in place, the ramp 92 is located outside gorges 89.

Lorsque l'utilisateur tourne le contenant supérieur 63 par rapport au contenant inférieur 61, la rampe 92 vient s'engager dans l'une des gorges 89 et appuie sur le fond de cette gorge, ce qui entraíne vers le bas l'obturateur 80. Ce dernier est empêché de tourner par les pattes 88 qui sont bloquées en rotation dans les gorges 99 et coulissent dans ces dernières.When the user turns the upper container 63 by compared to the lower container 61, the ramp 92 engages in one of the grooves 89 and presses on the bottom of this groove, which drives shutter 80 downwards. The latter is prevented from turn by the legs 88 which are locked in rotation in the gorges 99 and slide therein.

On a représenté sur les figures 14 et 15 le dispositif 60 après la rotation des deux contenants 61 et 63. Le composant contenu dans le contenant supérieur 63 peut s'écouler dans le contenant inférieur au travers des ajours 79. Le composant contenu dans l'obturateur 81 peut quitter ce dernier lorsque le dispositif 60 est retourné.FIGS. 14 and 15 show the device 60 after the rotation of the two containers 61 and 63. The component contained in the upper container 63 can flow into the lower container through the openings 79. The component contained in the shutter 81 can leave the latter when the device 60 is returned.

On a représenté sur les figures 18 à 20 un dispositif 100 conforme à un quatrième exemple de réalisation de l'invention.FIGS. 18 to 20 show a device 100 in accordance with a fourth embodiment of the invention.

Ce dispositif 100 comporte un contenant inférieur 101 à col 102 et un contenant supérieur 103 se présentant sous la forme d'une capsule encliquetée sur le col 102.This device 100 includes a lower container 101 with a neck 102 and an upper container 103 in the form of a capsule snapped onto collar 102.

Plus particulièrement, le contenant supérieur 103 comporte une jupe de montage 104 munie de reliefs 105 surmontés d'évidements, ces reliefs 105 étant destinés à s'encliqueter sur un bourrelet annulaire 106 réalisé sur la surface extérieure du col 102.More particularly, the upper container 103 comprises a mounting skirt 104 provided with reliefs 105 surmounted by recesses, these reliefs 105 being intended to snap onto an annular bead 106 produced on the outside surface of the neck 102.

La jupe 104 prend appui par son bord inférieur sur un épaulement du contenant inférieur 101 formé à la base du col 102, de sorte que le contenant supérieur 103 peut tourner par rapport au contenant inférieur sans se déplacer axialement.The skirt 104 is supported by its lower edge on a shoulder of the lower container 101 formed at the base of the neck 102, so that the upper container 103 can rotate relative to the lower container without moving axially.

Le contenant supérieur 103 comporte également une cheminée centrale 107 située à l'intérieur la jupe de montage 104 et une lèvre annulaire d'étanchéité 108 qui s'étend vers le bas dans l'espace annulaire qui existe entre la jupe de montage 104 et la cheminée 107.The upper container 103 also includes a chimney central 107 located inside the mounting skirt 104 and a lip sealing ring 108 which extends downwards in space annular which exists between the mounting skirt 104 and the chimney 107.

La lèvre 108 vient s'appliquer de façon étanche sur la surface radialement intérieure du col 102.The lip 108 is applied tightly to the surface radially inside of the neck 102.

La cheminée centrale 107 comporte deux filetages extérieurs 110 symétriques l'un de l'autre par rapport à l'axe X.The central chimney 107 has two external threads 110 symmetrical to each other with respect to the X axis.

Le col 102 comporte à sa base deux couples de portées 111 formant saillie vers l'intérieur, analogues aux portées 98 décrites en référence à la figure 17.The neck 102 has at its base two pairs of spans 111 protruding inwards, similar to the ranges 98 described with reference to Figure 17.

Les composants sont séparés avant la première utilisation du dispositif 100 par un obturateur 112 que l'on a représenté isolément sur la figure 20.The components are separated before the first use of the device 100 by a shutter 112 which has been shown in isolation in Figure 20.

Cet obturateur 112 comporte un bouchon constitué par un disque 113 muni sur sa face supérieure de deux lèvres annulaires d'étanchéité 114 et 115 concentriques et comprend également une couronne 116 raccordée au disque 113 par deux pattes 117 diamétralement opposées.This shutter 112 comprises a plug constituted by a disc 113 provided on its upper face with two annular lips sealing 114 and 115 concentric and also includes a crown 116 connected to the disc 113 by two legs 117 diametrically opposite.

Deux ergots 120 diamétralement opposés sont formés sur la face radialement intérieure de la couronne 116 pour venir en prise avec les filetages 110.Two diametrically opposite lugs 120 are formed on the face radially inner of the crown 116 to engage with the threads 110.

Les pattes 117 se logent dans les gorges formées entre les portées 111 et peuvent coulisser axialement dans celles-ci.The legs 117 are housed in the grooves formed between the carried 111 and can slide axially therein.

L'extrémité inférieure 123 de la cheminée 107 vient s'engager entre les lèvres 114 et 115 lorsque l'obturateur 112 est dans sa position initiale avant la première utilisation du dispositif, comme représenté sur la figure 18.The lower end 123 of the chimney 107 engages between the lips 114 and 115 when the shutter 112 is in its initial position before the first use of the device, such as shown in figure 18.

Pour provoquer le mélange des composants, l'utilisateur tourne le contenant supérieur 103 par rapport au contenant inférieur 101.To cause the components to mix, the user turns the upper container 103 relative to the lower container 101.

L'obturateur 112 étant empêché de tourner par rapport au contenant inférieur 101, les filetages 110 entraínent vers le bas les ergots 120, ce qui provoque l'ouverture de l'extrémité inférieure de la cheminée 107 comme représenté sur la figure 19 et la descente du composant contenu dans le contenant supérieur 103 dans le contenant inférieur 101.The shutter 112 being prevented from turning relative to the lower container 101, the threads 110 drive down the pins 120, which causes the opening of the lower end of the chimney 107 as shown in FIG. 19 and the descent of the component in the upper container 103 in the container lower 101.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the examples of realization which have just been described.

On peut notamment prévoir que l'embout de distribution soit porté par le contenant inférieur et non par le contenant supérieur comme cela a été décrit. On peut prévoir également un dispositif permettant une limitation angulaire de la rotation d'un des contenants par rapport à l'autre.One can in particular provide that the dispensing tip is carried by the lower container and not by the upper container as described. We can also provide a device allowing an angular limitation of the rotation of one of the containers relative to each other.

On remarquera que dans l'invention, le mélange des composants s'effectue à volume constant sans créer de surpression susceptible de projeter du mélange à l'ouverture du dispositif.It will be noted that in the invention, the mixture of the components takes place at constant volume without creating an overpressure liable to spray mixture at the opening of the device.
