Abstract

The two separate components (A,B) are contained in separate superposed containers (2,3) which can be rotated relative to each other in order to communicate. The two containers are sealed by a sealing lip (9) which is applied tightly on the internal radial surface of the upper part (10) of the neck (4). An obturator (12) comprising a plug (13) connected by a link (14) forming a hinge to a ring (15) seals the channel (7).

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 du type comportant deux contenants superposés, pouvant tourner l'un par rapport à l'autre et aptes à communiquer.The invention relates more particularly to a device of the type comprising two superimposed containers, which can rotate one by relationship with others and able to communicate.

Les composants sont séparés pendant le stockage par un obturateur qui comporte un bouchon relié par au moins un pont de matière formant charnière à un organe de maintien.The components are separated during storage by a obturator which has a plug connected by at least one bridge material forming a hinge to a holding member.

Ce type de dispositif comporte en outre des moyens d'entraínement pour transformer la rotation relative des deux contenants en un déplacement du bouchon provoquant le mélange des composants.This type of device also includes means to transform the relative rotation of the two containers in a displacement of the cap causing the mixing of components.

On connaít par le brevet français d'invention 2.506.726 au nom de la société déposante un tel dispositif, l'un des contenants étant constitué par un flacon à col fileté extérieurement. L'organe de maintien est constitué par une couronne insérée dans ce col et prenant appui par un rebord annulaire sur sa tranche. L'autre contenant est constitué par une capsule vissée sur le col, comportant une cheminée centrale sur laquelle s'applique la couronne précitée. L'obturateur comporte un bouchon fermant la cheminée pendant le stockage séparé des composants, relié par un pont de matière formant charnière à la couronne.We know by the French patent of invention 2.506.726 in the name of the company filing such a device, one of the containers being consisting of an externally threaded neck bottle. The organ of support is constituted by a crown inserted in this collar and taking support by an annular rim on its edge. The other container is consisting of a capsule screwed onto the neck, comprising a chimney central to which the above-mentioned crown is applied. The shutter has a cap closing the chimney during separate storage of components, connected by a hinge material bridge to the crowned.

L'étanchéité entre le flacon et la capsule est assurée par la compression de la couronne entre le col et la cheminée.The seal between the bottle and the capsule is ensured by the compression of the crown between the neck and the chimney.

Le vissage de la capsule sur le flacon provoque le pivotement du bouchon et la mise en communication de la capsule et du flacon. Le pont de matière reliant le bouchon à la couronne permet d'empêcher que ce dernier ne tombe dans le fond du flacon.The screwing of the capsule on the bottle causes the pivoting the cap and the communication of the capsule and the bottle. The material bridge connecting the cap to the crown prevents the latter does not fall into the bottom of the bottle.

La couronne doit être pressée fortement entre la cheminée et le col pour obtenir l'étanchéité requise, ce qui freine considérablement le mouvement de vissage de la capsule, de sorte que ce dispositif connu n'est pas d'une utilisation aisée. The crown must be pressed firmly between the chimney and the collar to obtain the required seal, which considerably slows down the screwing movement of the capsule, so that this device known is not easy to use.

L'invention vise à proposer un dispositif amélioré, remédiant notamment à cet inconvénient.The invention aims to propose an improved device, remedying especially to this drawback.

Elle y parvient par le fait que le dispositif comporte des moyens d'étanchéité indépendants de l'obturateur pour assurer l'étanchéité entre les deux contenants.It achieves this by the fact that the device includes sealing means independent of the shutter to ensure the seal between the two containers.

Dans une mise en oeuvre particulière de l'invention, ces moyens d'étanchéité comportent une lèvre annulaire d'étanchéité formée sur l'un des contenants et venant en contact étanche avec l'autre contenant.In a particular implementation of the invention, these means sealing have an annular sealing lip formed on one of the containers and coming into tight contact with the other container.

Toujours dans une mise en oeuvre particulière de l'invention, l'un des contenants se présente sous la forme d'un flacon comportant une ouverture et l'autre contenant se présente sous la forme d'une capsule comportant une lèvre annulaire d'étanchéité venant s'appliquer de façon étanche sur le flacon.Still in a particular implementation of the invention, one of the containers is in the form of a bottle comprising one opening and the other container is in the form of a capsule comprising an annular sealing lip which is applied tightly on the bottle.

Dans une réalisation particulière de l'invention, l'organe de maintien de l'obturateur se présente sous la forme d'une couronne insérée dans l'ouverture du flacon et bloquée en rotation par rapport à celui-ci, prenant appui par un rebord annulaire sur un épaulement intérieur de ladite ouverture, et la capsule comporte une cheminée centrale s'étendant à l'intérieur de la couronne et dans laquelle est inséré le bouchon, le bord libre de ladite cheminée formant une rampe hélicoïdale conformée pour appuyer progressivement sur le pont de matière formant charnière lors de la rotation relative des deux contenants, de manière à faire pivoter le bouchon hors de la cheminée.In a particular embodiment of the invention, the holding the shutter is in the form of a crown inserted into the opening of the bottle and locked against rotation with respect to to it, supported by an annular rim on a shoulder inside said opening, and the capsule has a chimney central extending inside the crown and in which is inserted the plug, the free edge of said chimney forming a ramp helical shaped to gradually press on the bridge hinge material during relative rotation of the two containers, so as to rotate the plug out of the chimney.

De préférence, la rampe comporte des encoches dans lesquelles se logent des ponts de matière sécables reliant le bouchon à l'organe de maintien, de manière à être rompus lors de la rotation relative des contenants.Preferably, the ramp has notches in which breakable material bridges connecting the plug to the organ holding, so as to be broken during the relative rotation of the containers.

De préférence encore, la couronne est crantée extérieurement et elle est immobilisée en rotation dans l'ouverture du flacon par des crans complémentaires formés sur la surface intérieure de ce dernier.More preferably, the crown is notched outwardly and it is immobilized in rotation in the opening of the bottle by complementary notches formed on the inner surface of the latter.

Dans une autre réalisation particulière de l'invention, l'organe de maintien comporte une patte de maintien bloquée en rotation par rapport à la capsule, se logeant dans un espace annulaire formée entre la capsule et le flacon, ce dernier présentant sur sa surface intérieure une rampe hélicoïdale sur laquelle vient en appui la patte de maintien, de sorte que la rotation relative des deux contenants tend à exercer une traction sur celle-ci et à déplacer le bouchon pour ouvrir le passage entre les deux contenants.In another particular embodiment of the invention, the holding member comprises a holding tab locked in rotation relative to the capsule, housed in an annular space formed between the capsule and the bottle, the latter on its inner surface a helical ramp on which comes to rest the holding tab, so that the relative rotation of the two containers tends to pull on it and move the plug to open the passage between the two containers.

De préférence, la capsule présente une encoche dans laquelle se loge le pont de matière reliant le bouchon à la patte de maintien, de manière à bloquer en rotation le bouchon par rapport à la capsule.Preferably, the capsule has a notch in which houses the material bridge connecting the plug to the retaining tab, so as to block the cap in rotation relative to the capsule.

Dans une autre réalisation particulière de l'invention, l'organe de maintien comporte une patte de maintien bloquée en rotation par rapport au flacon et coopérant par vissage avec la capsule.In another particular embodiment of the invention, the holding member comprises a holding tab locked in rotation relative to the bottle and cooperating by screwing with the capsule.

De préférence, le flacon comporte une gorge dans laquelle se loge cette patte de maintien, de sorte qu'elle est immobilisée en rotation par rapport au flacon tout en pouvant se déplacer axialement par rapport à celui-ci lors de la rotation relative des contenants.Preferably, the bottle has a groove in which is houses this holding tab, so that it is immobilized in rotation relative to the bottle while being able to move axially relative to it during the relative rotation of the containers.

Dans une autre réalisation particulière de l'invention, l'organe de maintien se présente sous la forme d'une couronne bloquée en rotation par rapport au flacon, coopérant par vissage avec la capsule.In another particular embodiment of the invention, the holding member is in the form of a blocked crown in rotation relative to the bottle, cooperating by screwing with the capsule.

L'ouverture du flacon peut être constituée par un col ou en variante par un fond ouvert.The opening of the bottle can be constituted by a neck or by variant with an open bottom.

Le dispositif de conditionnement 1 représenté sur les figures 1 et 4 comporte un contenant inférieur 2 et un contenant supérieur 3 pouvant tourner l'un par rapport à l'autre autour de l'axe longitudinal X du dispositif.The conditioning device 1 shown in Figures 1 and 4 has a lower container 2 and an upper container 3 can rotate relative to each other about the axis longitudinal X of the device.

Le contenant inférieur 2 se présente sous la forme d'un flacon, dont le col 4 comporte un épaulement extérieur 5.The lower container 2 is in the form of a bottle, whose neck 4 has an outer shoulder 5.

Le contenant supérieur 3 se présente sous la forme d'une capsule dont la partie supérieure est formée par un embout de distribution 6 fileté extérieurement, sur lequel se visse un capuchon 11.The upper container 3 is in the form of a capsule, the upper part of which is formed by a distribution 6 externally threaded, on which a cap 11.

La capsule 3 comporte à sa partie inférieure une cheminée centrale 7 entourée par une jupe de montage 8, laquelle est pourvue sur sa surface radialement intérieure d'un bourrelet annulaire encliqueté sur l'épaulement 5 précité.The capsule 3 has at its lower part a chimney central 7 surrounded by a mounting skirt 8, which is provided on its radially inner surface of an annular bead snapped onto the aforementioned shoulder 5.

Le bord inférieur de la jupe de montage 8 repose sur l'épaulement du flacon situé à la base du col 4, de sorte que la capsule 3 est immobilisée axialement par rapport au flacon 2.The lower edge of the mounting skirt 8 rests on the shoulder of the bottle located at the base of the neck 4, so that the capsule 3 is immobilized axially relative to the bottle 2.

La capsule 3 comporte également une lèvre annulaire d'étanchéité 9 s'étendant vers le bas dans la gorge annulaire formée entre la cheminée 7 et la jupe de montage 8.The capsule 3 also has an annular lip seal 9 extending downward into the annular groove formed between the chimney 7 and the mounting skirt 8.

Cette lèvre d'étanchéité 9, qui est symétrique de révolution autour de l'axe X, vient s'appliquer étroitement sur la surface radialement intérieure de la partie supérieure 10 du col 4, cylindrique de révolution autour de l'axe X, de manière à assurer l'étanchéité entre la capsule 3 et le flacon 2.This sealing lip 9, which is symmetrical in revolution around the X axis, is applied tightly on the surface radially interior of the upper part 10 of the neck 4, cylindrical of revolution around the X axis, so as to ensure the seal between the capsule 3 and the bottle 2.

La capsule 3 est munie extérieurement de nervures de préhension 21, destinées à faciliter le maniement du dispositif par l'utilisateur.The capsule 3 is externally provided with ribs of gripping 21, intended to facilitate the handling of the device by the user.

Le flacon 2 et la capsule 3 sont destinés à contenir respectivement deux composants A et B devant être stockés séparément et à mélanger lors de la première utilisation. Les composants A et B peuvent être deux liquides ou un liquide et une poudre. Le composant A est par exemple un oxydant et le composant B un colorant, dont le mélange M constitue une teinture capillaire.The bottle 2 and the capsule 3 are intended to contain respectively two components A and B to be stored separately and mix during the first use. Components A and B can be two liquids or a liquid and a powder. Component A is for example an oxidant and component B a dye, the mixture M constitutes a hair dye.

Un obturateur 12 permet d'obturer la cheminée 7 pendant le stockage séparé des composants A et B. A shutter 12 makes it possible to close the chimney 7 during the separate storage of components A and B.

On a représenté isolément sur les figures 2 et 3 cet obturateur 12, qui comporte un bouchon 13 relié par un pont de matière 14 formant charnière à un organe de maintien, lequel se présente ici sous la forme d'une couronne 15, s'étendant à l'intérieur du col 4 autour de la cheminée 7.Is shown separately in Figures 2 and 3 this shutter 12, which has a plug 13 connected by a bridge material 14 forming a hinge to a holding member, which here in the form of a crown 15, extending inside from the neck 4 around the chimney 7.

Le bouchon 13 comporte sur sa face supérieure une lèvre annulaire d'étanchéité 16 destinée à s'insérer dans la cheminée 7 pour fermer celle-ci de façon étanche.The plug 13 has on its upper face a lip sealing ring 16 intended to be inserted in the chimney 7 for close it tightly.

On remarquera à l'examen des figures 1 à 4 que le bouchon 13 comporte à sa périphérie un épaulement 13a destiné à venir en appui sur un épaulement intérieur de la cheminée 7.It will be noted in examining the figures 1-4 the cap 13 comprises on its periphery a shoulder 13 is intended to bear against an inner shoulder of the shaft 7.

La couronne 15 comporte à son extrémité supérieure un rebord annulaire 17, formant radialement saillie vers l'extérieur, destiné à prendre appui sur un épaulement intérieur 22 du col 4, situé sous la lèvre d'étanchéité 9.The crown 15 has at its upper end a rim annular 17, radially projecting outwards, intended for lean on an inner shoulder 22 of the neck 4, located under the sealing lip 9.

Une pluralité de crans 18 sont réalisés sur la surface radialement extérieure de la couronne 15 sous le rebord 17 et coopèrent avec des crans complémentaires 19 formés sur le col 4 pour bloquer en rotation la couronne 15 par rapport au flacon 2.A plurality of notches 18 are formed on the surface radially outside of the crown 15 under the rim 17 and cooperate with complementary notches 19 formed on the neck 4 to rotationally block the crown 15 relative to the bottle 2.

La cheminée 7 présente un bord inférieur constituant une rampe hélicoïdale 20 s'étendant angulairement autour de l'axe X sur un peu plus d'un demi-tour.The chimney 7 has a lower edge constituting a ramp helical 20 extending angularly around the X axis on a little more than half a turn.

En dehors de cette rampe 20, le bord inférieur de la cheminée 7 s'étend selon un plan perpendiculaire à l'axe X, situé légèrement au dessus du pont de matière 14.Outside this ramp 20, the lower edge of the chimney 7 extends along a plane perpendicular to the X axis, located slightly at above the material bridge 14.

La capsule 3 et le flacon 2 sont réalisés dans des matériaux chimiquement compatibles avec les composants A et B.The capsule 3 and the bottle 2 are made of materials chemically compatible with components A and B.

La capsule 3 est réalisée par exemple en polychlorure de vinyle, le flacon 2 en polyéthylène et l'obturateur 12 en polypropylène.The capsule 3 is made for example of polychloride of vinyl, the polyethylene bottle 2 and the shutter 12 in polypropylene.

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

La capsule 3, munie du capuchon 2, est remplie avec le composant B puis le bouchon 13 est inséré dans la cheminée 7.The capsule 3, provided with the cap 2, is filled with the component B then the plug 13 is inserted into the chimney 7.

On veille à décaler angulairement la rampe 20 et le pont de matière 14. Care is taken to angularly offset the ramp 20 and the bridge material 14.

La capsule 3 est ensuite introduite par un simple mouvement de translation dans le col 4 du flacon 2, rempli au préalable avec le composant A.The capsule 3 is then introduced by a simple movement of translation into the neck 4 of the bottle 2, previously filled with the component A.

La jupe de montage 8 s'encliquette alors sur le col 4.The mounting skirt 8 then snaps onto the neck 4.

On veille bien entendu à positionner correctement les crans 18 de la couronne 15 par rapport aux crans 19 du col 4.Care is taken of course to correctly position the notches 18 of the crown 15 relative to the notches 19 of the neck 4.

Pour provoquer la mise en communication de la capsule 3 et du flacon 2, lors de la première utilisation du dispositif, l'utilisateur tourne la capsule 3 par rapport au flacon 2 d'un demi-tour environ, dans le sens qui amène progressivement la rampe hélicoïdale 20 à appuyer vers le bas sur le pont de matière 14.To cause the connection of capsule 3 and the bottle 2, when the device is used for the first time, the user rotates the capsule 3 relative to the bottle 2 by about half a turn, in the direction which gradually brings the helical ramp 20 to press down on the material bridge 14.

Ceci provoque, la couronne 15 étant empêchée de tourner par rapport au flacon et retenue axialement dans le col 4 grâce au rebord 17, le pivotement du bouchon 13 autour d'un axe géométrique de rotation perpendiculaire au plan du dessin.This causes, the crown 15 being prevented from rotating by relation to the bottle and retained axially in the neck 4 thanks to the rim 17, the pivoting of the plug 13 around a geometric axis of rotation perpendicular to the drawing plane.

Le composant B tombe dans le flacon 2 et se mélange au composant A.Component B falls into bottle 2 and mixes with component A.

Du fait que la cheminée 7 s'étend jusqu'à la base du col 4, il n'existe aucun recoin susceptible de retenir le composant B qui tombe en totalité dans le flacon.Because the chimney 7 extends to the base of the neck 4, it there is no corner capable of retaining the falling component B entirely in the bottle.

On évite ainsi qu'une fraction du composant B soit distribuée sans avoir été mise au préalable au contact du composant A.This prevents a fraction of component B from being distributed without having been put in contact with component A beforehand.

On remarquera en outre que la section transversale de la cheminée 7 à son extrémité inférieure est relativement grande, de sorte que le composant B tombe quasiment instantanément dans le flacon, même s'il présente une viscosité importante.It will also be noted that the cross section of the chimney 7 at its lower end is relatively large, of so that component B almost instantly falls into the bottle, even if it has a high viscosity.

Le bouchon 13 est empêché de tomber dans le fond du flacon 2 par le pont de matière 14, et ne gène pas l'écoulement du composant B dans le flacon.The stopper 13 is prevented from falling into the bottom of the bottle 2 through the material bridge 14, and does not hinder the flow of component B in the bottle.

Lorsque le mélange M est distribué, le bouchon 13 n'est pas non plus susceptible de gêner son écoulement.When the mixture M is dispensed, the cap 13 is also not more likely to interfere with its flow.

On remarquera qu'une fois que les composants A et B sont mélangés, il n'est plus possible de ramener par une rotation inverse de la capsule 3, le bouchon 13 dans sa position initiale. Note that once components A and B are mixed, it is no longer possible to bring back by a reverse rotation of the capsule 3, the plug 13 in its initial position.

On remarquera également que le mélange des composants d'effectue à volume constant, car il n'y a pas de déplacement axial de la capsule 3 par rapport au flacon 2.It will also be noted that the mixture of the components at constant volume, because there is no axial displacement of the capsule 3 relative to the bottle 2.

Ainsi, on évite l'apparition d'une surpression à l'intérieur du dispositif 1 et tout risque de projection de mélange M lors du retrait du capuchon 11.This avoids the appearance of an overpressure inside the device 1 and any risk of projection of mixture M during withdrawal the cap 11.

L'étanchéité entre le flacon 2 et la capsule 3 est assurée par la lèvre d'étanchéité 9, sans qu'il en résulte un freinage important du mouvement de rotation de la capsule 3 par rapport au flacon 2.The seal between the bottle 2 and the capsule 3 is ensured by the sealing lip 9, without resulting in significant braking of the rotational movement of the capsule 3 relative to the bottle 2.

Par ailleurs, grâce à l'élasticité radiale de la lèvre d'étanchéité 9, on peut réaliser le flacon 2 et la capsule 3 avec des tolérances de fabrication relativement larges.In addition, thanks to the radial elasticity of the lip seal 9, the bottle 2 and the capsule 3 can be produced with relatively wide manufacturing tolerances.

On va maintenant décrire, en référence aux figures 5 à 7, un dispositif 23 conforme à un deuxième exemple de réalisation de l'invention, qui diffère du précédent par la forme de l'obturateur et celle de l'extrémité inférieure de la cheminée centrale.We will now describe, with reference to FIGS. 5 to 7, a device 23 according to a second exemplary embodiment of the invention, which differs from the previous one by the shape of the shutter and that of the lower end of the central chimney.

On utilisera les mêmes références pour désigner des éléments constitutifs identiques, qui ne seront pas décrits à nouveau.We will use the same references to designate elements identical components, which will not be described again.

L'obturateur du dispositif 23, référencé 12', diffère de l'obturateur 12 précédemment décrit par le fait que trois ponts de matière sécables 24 relient le bouchon 13 à la couronne 15 en plus du pont de matière 14, comme on peut le voir sur la figure 5.The shutter of the device 23, referenced 12 ′, differs from the shutter 12 previously described by the fact that three bridges of breakable material 24 connect the plug 13 to the crown 15 in addition to the material bridge 14, as can be seen in FIG. 5.

La capsule du dispositif 23, référencée 3', diffère de la capsule 3 précédemment décrite par la forme de l'extrémité inférieure de la cheminée, référencée 7'.The capsule of the device 23, referenced 3 ′, differs from the capsule 3 previously described by the shape of the lower end from the chimney, referenced 7 '.

Des encoches 25 sont formées sur le bord inférieur de cette cheminée 7' pour loger les ponts de matière 24 lorsque le bouchon 13 ferme la capsule 3'.Notches 25 are formed on the lower edge of this chimney 7 'for housing the material bridges 24 when the plug 13 closes the 3 'capsule.

Lors de la rotation de celle-ci par rapport au flacon 2, qui provoque le pivotement du bouchon 13 et le mélange des composants A et B, les bords de ces encoches 25 fracturent les ponts de matière 24.When the latter is rotated relative to the bottle 2, which causes the plug 13 to pivot and the components A to mix and B, the edges of these notches 25 fracture the bridges of material 24.

La rupture de ces derniers est clairement perceptible par l'utilisateur, qui dispose ainsi d'un témoin d'inviolabilité.The rupture of these is clearly noticeable by the user, who thus has a witness of inviolability.

Le dispositif 23 présente les mêmes avantages que le dispositif 1 précédemment décrit. The device 23 has the same advantages as the device 1 previously described.

On a représenté sur la figure 8 un dispositif 26 conforme à un troisième exemple de réalisation de l'invention.FIG. 8 shows a device 26 conforming to a third embodiment of the invention.

Ce dispositif 26 comporte un contenant supérieur 27 et un contenant inférieur 28 pouvant tourner l'un par rapport à l'autre autour de l'axe longitudinal X du dispositif.This device 26 comprises an upper container 27 and a lower container 28 rotatable relative to each other around the longitudinal axis X of the device.

Le contenant supérieur 27 se présente ici sous la forme d'un flacon ouvert à sa partie inférieure et le contenant inférieur 28 est constitué par une capsule formant culot, insérée dans cette ouverture du flacon.The upper container 27 is here in the form of a open bottle at its bottom and the bottom container 28 is consisting of a capsule forming a base, inserted into this opening from the bottle.

Le flacon 27 comporte à sa partie supérieure un embout de distribution fileté 29, obturé par un capuchon amovible 30.The bottle 27 has at its upper part a mouthpiece threaded distribution 29, closed by a removable cap 30.

Un étranglement 31 est formé à la partie inférieure du flacon 27, pour définir un épaulement extérieur 32 et un épaulement intérieur 33.A constriction 31 is formed at the bottom of the bottle 27, to define an outer shoulder 32 and a shoulder interior 33.

Le culot 28 comporte une cheminée centrale 34 entourée par une jupe de montage 35, laquelle présente un bourrelet annulaire 36 venant s'encliqueter sur l'épaulement extérieur 32 précité.The base 28 has a central chimney 34 surrounded by a mounting skirt 35, which has an annular bead 36 coming from snap onto the above-mentioned outer shoulder 32.

Une lèvre annulaire d'étanchéité 37, cylindrique de révolution autour de l'axe X, et destinée à s'appliquer de façon étanche sur la surface radialement intérieure 38 de la partie inférieure du flacon 27, s'étend vers le haut entre la cheminée 34 et la jupe de montage 35.An annular sealing lip 37, cylindrical of revolution around the X axis, and intended to be applied sealingly on the radially inner surface 38 of the lower part of the bottle 27, extends upwards between the chimney 34 and the mounting skirt 35.

Un obturateur 39 permet d'assurer le stockage séparé des composants A et B contenus respectivement dans le flacon 27 et dans la cheminée 34 avant la première utilisation du dispositif 26.A shutter 39 ensures separate storage of components A and B contained respectively in the bottle 27 and in the chimney 34 before the first use of the device 26.

Cet obturateur 39 comporte un bouchon 40 relié par un pont de matière 41 formant charnière à une couronne 42, laquelle est pourvue à son extrémité inférieure d'un rebord annulaire 43 capable de prendre appui sous l'épaulement intérieur 33 précité.This shutter 39 comprises a plug 40 connected by a bridge of material 41 forming a hinge to a crown 42, which is provided with its lower end of an annular rim 43 capable of taking support under the aforementioned inner shoulder 33.

Des crans 44 sont formés respectivement sur la couronne 42 au voisinage du rebord annulaire 43 et sur l'étranglement 31 pour assurer l'immobilisation en rotation de la couronne 42 par rapport au flacon 27.Notches 44 are formed respectively on the crown 42 at vicinity of the annular rim 43 and on the constriction 31 to ensure immobilization in rotation of the crown 42 relative to the bottle 27.

L'obturateur 39 coiffe la cheminée 34 lorsqu'il est dans sa position initiale.The shutter 39 covers the chimney 34 when it is in its initial position.

Le bord supérieur de la cheminée 34 forme une rampe hélicoïdale 69 permettant, lorsque le culot 28 est entraíné en rotation par rapport au flacon 27, d'exercer progressivement une poussée vers le haut sur le pont de matière 41 et de provoquer le pivotement du bouchon 40 vers le haut, la couronne 42 étant bloquée axialement par l'appui du rebord 43 sous l'épaulement 33.The upper edge of the chimney 34 forms a helical ramp 69 allowing, when the base 28 is driven in rotation relative to the bottle 27, to gradually exert a push up on the material bridge 41 and cause the pivoting of the plug 40 upwards, the crown 42 being blocked axially by the support of the rim 43 under the shoulder 33.

De préférence, on effectue la rotation du culot 28 par rapport au flacon 27 en maintenant ce dernier en bas, car sinon le composant A serait retenu dans l'espace annulaire situé à l'extérieur de la cheminée 34 et ne se mélangerait que partiellement au composant B.Preferably, the base 28 is rotated relative to to bottle 27 while keeping it at the bottom, because otherwise component A would be retained in the annular space located outside the chimney 34 and would only partially mix with component B.

On a représenté sur les figures 9 et 10 un dispositif 45 conforme à un quatrième exemple de réalisation de l'invention.FIGS. 9 and 10 show a device 45 in accordance with a fourth embodiment of the invention.

Ce dispositif 45 comporte un contenant inférieur constitué par un flacon 46 à col 47 et un contenant supérieur constitué par une capsule 48, pouvant tourner par rapport au flacon 46.This device 45 comprises a lower container constituted by a bottle 46 with a neck 47 and an upper container constituted by a capsule 48, which can rotate relative to the bottle 46.

La capsule 48 comporte une cheminée centrale 49 entourée par une jupe de montage 50 et, entre les deux, une lèvre annulaire d'étanchéité 51.The capsule 48 has a central chimney 49 surrounded by a mounting skirt 50 and, between the two, an annular lip seal 51.

Un embout 52 pour la distribution du mélange M est formé à l'extrémité supérieure de la capsule 48. Cet embout 52 est obturé par un capuchon amovible 53, retenu par friction.A nozzle 52 for the distribution of the mixture M is formed at the upper end of the capsule 48. This end piece 52 is closed by a removable cap 53, retained by friction.

Le col 47 comporte un épaulement extérieur 58 sur lequel vient s'encliqueter un bourrelet annulaire 57 de la jupe de montage 50.The neck 47 has an outer shoulder 58 on which comes snap on an annular bead 57 of the mounting skirt 50.

La lèvre d'étanchéité 51 s'applique sur la surface radialement intérieure du col 47 et assure l'étanchéité entre la capsule 48 et le flacon 46.The sealing lip 51 is applied to the surface radially inside of the neck 47 and provides sealing between the capsule 48 and the bottle 46.

La cheminée 49 comporte à sa partie inférieure deux parois concentriques 60 et 61, formant entre elles une gorge annulaire 62.The chimney 49 has at its lower part two walls concentric 60 and 61, forming between them an annular groove 62.

La paroi 61, radialement la plus externe, se prolonge vers le bas par rapport à la paroi 60.The wall 61, radially outermost, extends towards the low relative to the wall 60.

Les composants A et B contenus respectivement dans le flacon 46 et la capsule 48 sont séparés pendant le stockage par un obturateur 63.Components A and B contained in bottle 46, respectively and the capsule 48 are separated during storage by a shutter 63.

Cet obturateur 63 comporte un bouchon 64 muni à sa périphérie de deux lèvres annulaires d'étanchéité 65 et 66, concentriques, formant une gorge dans laquelle pénètre la paroi 60 lors de la fermeture étanche de la capsule 48.This shutter 63 includes a plug 64 provided at its periphery two concentric annular sealing lips 65 and 66, forming a groove into which the wall 60 penetrates during the tight closure of the capsule 48.

La lèvre 66, radialement la plus externe, vient alors se loger dans la gorge 62 précitée. The radially outermost lip 66 then comes to be housed in the aforementioned groove 62.

Le col 47 est relié au reste du flacon 46 par un étranglement 54 dont la face supérieure forme une rampe hélicoïdale 55.The neck 47 is connected to the rest of the bottle 46 by a constriction 54, the upper face of which forms a helical ramp 55.

Le bouchon 64 est relié par un pont de matière 67 formant charnière à une patte de maintien 68 qui prend appui sur la rampe 55.The plug 64 is connected by a material bridge 67 forming hinge to a retaining lug 68 which bears on the ramp 55.

Le pont de matière 67 repose dans le fond d'une encoche 70 réalisée dans la paroi 61, et de même largeur que celui-ci, de sorte que le bouchon 64 est empêché de tourner par rapport à la capsule 48.The material bridge 67 rests in the bottom of a notch 70 made in the wall 61, and of the same width as the latter, so that the plug 64 is prevented from rotating relative to the capsule 48.

Lorsque l'utilisateur tourne la capsule 48 par rapport au flacon 46, l'obturateur 63 est ainsi entraíné en rotation avec celle-ci.When the user turns the capsule 48 relative to the bottle 46, the shutter 63 is thus rotated with this one.

Au fur et à mesure de la rotation de la capsule 48, la patte de maintien 68 est tirée vers le haut par la rampe 55, ce qui exerce une traction sur le pont de matière 67 et tend à faire pivoter vers le bas le bouchon 64, qui finit par se dégager de la cheminée 49 et prendre la position représentée sur la figure 10, permettant le mélange des composants A et B.As the capsule 48 rotates, the tab of support 68 is pulled upwards by the ramp 55, which exerts a traction on material bridge 67 and tends to pivot downwards the plug 64, which ends up emerging from the chimney 49 and taking the position shown in Figure 10, allowing the mixing of components A and B.

On a représenté sur les figures 11 et 13 un dispositif 75 conforme à un cinquième exemple de réalisation de l'invention.FIGS. 11 and 13 show a device 75 according to a fifth embodiment of the invention.

Ce dispositif 75 comporte un contenant inférieur constitué par un flacon 76 à col 77 et un contenant supérieur constitué par une capsule 78 pouvant tourner par rapport au flacon 76.This device 75 comprises a lower container constituted by a bottle 76 with a neck 77 and an upper container constituted by a capsule 78 which can rotate relative to the bottle 76.

Cette capsule 78 est munie à son extrémité supérieure d'un embout 79 sécable.This capsule 78 is provided at its upper end with a 79 breakable tip.

Le col 77 présente sur sa surface radialement extérieure un bourrelet annulaire 80 et la capsule 78 comporte une jupe de montage 81 pourvue de reliefs 82 surmontés d'évidements, ces reliefs 82 s'étendant chacun sur un peu moins d'un huitième de tour par exemple. Les reliefs 82 sont destinés à s'encliqueter le bourrelet annulaire 80 pour retenir axialement la capsule 78 sur le flacon 76, tout en autorisant une possibilité de rotation relative entre les deux.The neck 77 has on its radially outer surface a annular bead 80 and the capsule 78 has a mounting skirt 81 provided with reliefs 82 surmounted by recesses, these reliefs 82 each spanning just under an eighth of a turn, for example. The reliefs 82 are intended to snap on the annular bead 80 for axially retaining the capsule 78 on the bottle 76, while allowing a possibility of relative rotation between the two.

La capsule 78 comporte une cheminée centrale 83, s'étendant à l'intérieur de la jupe de montage 81, et comporte également entre cette dernière et la cheminée 83, une lèvre annulaire d'étanchéité 84 s'appliquant sur la surface radialement intérieure du col 77 pour assurer l'étanchéité entre la capsule 78 et le flacon 76, à l'instar des exemples de réalisation précédents. The capsule 78 has a central chimney 83, extending to inside the mounting skirt 81, and also has between the latter and the chimney 83, an annular sealing lip 84 applying to the radially inner surface of the neck 77 for sealing between the capsule 78 and the bottle 76, like examples of previous embodiments.

Les composants A et B respectivement contenus dans le flacon 79 et la capsule 78 sont séparés pendant le stockage par un obturateur 85, lequel comporte un bouchon 86 relié par un pont de matière 87 formant charnière à une patte de maintien 88.Components A and B respectively contained in bottle 79 and the capsule 78 are separated during storage by a shutter 85, which has a plug 86 connected by a material bridge 87 forming a hinge to a retaining tab 88.

Le bouchon 86 est pourvu, au voisinage de sa périphérie et sur sa face supérieure, d'une lèvre annulaire d'étanchéité 89 venant s'insérer dans la cheminée 83 pour fermer de façon étanche cette dernière.The plug 86 is provided, in the vicinity of its periphery and on its upper face, with an annular sealing lip 89 coming insert into the chimney 83 to seal this last.

La cheminée 83 présente en outre un filetage 90 sur sa surface radialement extérieure, et la patte de maintien 88 comporte, sur sa face radialement intérieure, une portion de filet 91 qui est en prise dans ce filetage 90.The chimney 83 also has a thread 90 on its surface radially outer, and the retaining tab 88 has, on its radially inner face, a portion of thread 91 which is engaged in this thread 90.

Le col 77 du flacon 76 comporte par ailleurs, sur sa surface intérieure, deux portées 92 qui ménagent entre elles une gorge 93 dans laquelle se loge la patte de maintien 88.The neck 77 of the bottle 76 also has, on its surface interior, two spans 92 which provide a groove 93 therebetween which houses the retaining tab 88.

On empêche ainsi l'obturateur 85 de tourner par rapport au col 77 du flacon 76 tout en permettant à la patte 88 de se déplacer axialement par rapport au col 77 dans la gorge 93.This prevents the shutter 85 from rotating relative to the neck 77 of bottle 76 while allowing tab 88 to move axially with respect to the neck 77 in the groove 93.

Lorsque la capsule 78 est entraínée en rotation par rapport au flacon 76 dans le sens adéquat, la portion de filet 91 de la patte de maintien 88 est tirée vers le haut par le filetage 90 de la cheminée 83.When the capsule 78 is rotated relative to the bottle 76 in the correct direction, the portion of net 91 of the tab of support 88 is pulled upwards by the thread 90 of the chimney 83.

La traction qui est alors exercée sur la patte de maintien 88 tend à faire pivoter le bouchon 86 vers le bas autour de sa zone d'appui sur le bord inférieur de la cheminée 83, adjacente au pont de matière 87.The traction which is then exerted on the holding tab 88 tends to rotate plug 86 down around its area bearing on the lower edge of the chimney 83, adjacent to the deck matter 87.

On a représenté sur les figures 14 et 16 un dispositif 95 conforme à un sixième exemple de réalisation de l'invention.FIGS. 14 and 16 show a device 95 according to a sixth embodiment of the invention.

Ce dispositif 95 comporte un flacon 76 et une capsule 78 identiques à ceux de l'exemple de réalisation précédent et qui ne seront par conséquent pas décrits à nouveau.This device 95 comprises a bottle 76 and a capsule 78 identical to those of the previous embodiment example and which do not will therefore not be described again.

Le dispositif 95 diffère du dispositif 75 par la structure de l'obturateur, qui est maintenant référencé 85'.The device 95 differs from the device 75 by the structure of the shutter, which is now referenced 85 '.

Cet obturateur 85' comporte un bouchon 86 relié par un pont de matière 87 formant charnière à un organe de maintien 96, se présentant sous la forme d'une couronne pourvue sur sa face radialement intérieure de quatre portions de filet 97 régulièrement espacées, qui s'étendent chacune sur un secteur angulaire de 45° environ.This shutter 85 'has a plug 86 connected by a bridge of material 87 forming a hinge to a holding member 96, presenting in the form of a crown provided on its face radially interior of four evenly spaced portions of filet 97 which each extend over an angular sector of approximately 45 °.

La couronne 96 est en outre reliée au bouchon 86 par trois ponts de matière sécables 99, répartis sur sa périphérie.The crown 96 is further connected to the plug 86 by three breakable material bridges 99, distributed around its periphery.

Lorsque la capsule 78 est entraínée en rotation par rapport au flacon 76, les portions de filet 97 qui sont en prise sur le filetage 90 exercent une traction vers le haut qui entraíne, dans un premier temps, la rupture des ponts de matière 99 puis, dans un deuxième temps, le pivotement du bouchon 86 autour de sa zone d'appui sur la cheminée 83, comme pour l'exemple de réalisation précédemment décrit.When the capsule 78 is rotated relative to the bottle 76, the portions of net 97 which are engaged on the thread 90 exert an upward traction which leads, in a first, the breaking of the material bridges 99 then, in a second time, the pivoting of the plug 86 around its support zone on the chimney 83, as for the example of embodiment previously described.

On a représenté sur la figure 17 un dispositif 100 conforme à un septième exemple de réalisation de l'invention.FIG. 17 shows a device 100 in accordance with a seventh exemplary embodiment of the invention.

Ce dispositif 100 diffère du dispositif 95 précédemment décrit par la forme des contenants inférieur et supérieur.This device 100 differs from the device 95 previously described by the shape of the upper and lower containers.

Le contenant inférieur 101 diffère de la capsule 78 précédemment décrite par l'absence d'embout de distribution, lequel est réalisé avec le flacon 102.The lower container 101 differs from the capsule 78 previously described by the absence of a distribution nozzle, which is made with the bottle 102.

Dans les exemples de réalisation qui viennent d'être décrits, on remarquera que le bouchon commence à se déplacer par rapport à la cheminée dans laquelle il est inséré sous l'effet de forces de traction et de torsion.In the exemplary embodiments which have just been described, we will notice that the plug begins to move relative to the chimney into which it is inserted under the effect of forces of traction and torsion.

Il en découle que le dégagement du bouchon est facilité, ce qui va dans le sens d'une réduction de l'effort à exercer pour provoquer le mélange des composants A et B en faisant tourner l'un des contenants par rapport à l'autre.It follows that the release of the plug is facilitated, which goes in the direction of a reduction in the effort to exert to cause mixing components A and B by rotating one of the containers relative to each other.

Par ailleurs, on remarquera que dans les exemples décrits, l'assemblage des contenants s'effectue aisément par un simple encliquetage sans avoir à visser l'un des contenants sur l'autre, et qu'après leur assemblage les contenants ne peuvent pas être désassemblés par l'utilisateur.Furthermore, it will be noted that in the examples described, the assembly of the containers is carried out easily by a simple snap-on without having to screw one of the containers onto the other, and that after assembly the containers cannot be disassembled by the user.

Par ailleurs, une bonne étanchéité entre les deux contenants est obtenue grâce à l'invention sans qu'il en résulte un freinage important du mouvement de rotation d'un contenant par rapport à l'autre, à la différence du dispositif de l'art antérieur décrit dans le brevet français 2.506.726 précité. In addition, a good seal between the two containers is obtained thanks to the invention without resulting in braking important rotation movement of a container relative to the other, unlike the device of the prior art described in the aforementioned French patent 2,506,726.

Le mélange des composants s'effectue à volume constant, ce qui permet d'éviter les projections, comme expliqué plus haut.The components are mixed at a constant volume, which avoids projections, as explained above.

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 combiner certaines caractéristiques des divers exemples de réalisation décrits pour en réaliser des variantes. On peut prévoir également un dispositif permettant une limitation angulaire de la rotation d'un des contenants par rapport à l'autre.We can in particular combine certain characteristics of various embodiments described to make variants thereof. One can also provide a device allowing a limitation angular rotation of one of the containers relative to the other.

Ainsi, on peut appliquer les particularités de réalisation des dispositifs comportant un flacon surmonté d'une capsule rotative aux dispositifs comportant un flacon à fond ouvert muni d'un culot rotatif et réciproquement.Thus, we can apply the special features of realization of devices comprising a bottle surmounted by a rotating capsule with devices with an open bottom flask fitted with a rotating base and reciprocally.
