Description

La présente invention concerne la fermeture de récipients pouvant contenir des matières quelconques telles que des matières alimentaires, cosmétiques, médicamenteuses, chimiques ou autres, ces matières se présentant indifféremment sous la forme de liquides, de poudres, de granulés ou de paillettes.The present invention relates to the closure of containers which may contain any material such as food, cosmetic, medicinal, chemical or other materials, these materials being either in the form of liquids, powders, granules or flakes.

On sait que la plupart des matières devant être conservées doivent être isolées de l'atmosphère.It is known that most of the materials to be stored must be isolated from the atmosphere.

A cette fin, il est courant dans la technique de sceller le récipient contenant la matière par une pellicule qui peut être en aluminium, en matière synthétique, en papier imprégné,etc.To this end, it is common in the technique of sealing the container containing the material with a film which may be made of aluminum, synthetic material, impregnated paper, etc.

La pellicule est mise en place et scellée au récipient éventuellement après que le vide y ait été fait pour éviter toute oxydation de la matière contenue.The film is put in place and sealed in the container if necessary after the vacuum has been created in it to avoid any oxidation of the material contained.

Pour protéger la pellicule et pour permettre l'utilisation en plusieurs fois de la matière, un couvercle est ensuite mis en place sur le récipient.To protect the film and to allow the material to be used several times, a cover is then placed on the container.

Les réalisations, rappelées ci-dessus, bien connues nécessitent, au moment de l'utilisation, de retirer le couvercle puis de découper la pellicule de protection qui, jusqu'à présent, sert également d'élément d'inviolabilité.The embodiments, recalled above, well known require, at the time of use, to remove the cover and then to cut the protective film which, until now, also serves as an element of tamper-evident.

L'invention concerne un dispositif de fermeture perfectionné qui présente toutes les qualités des dispositifs rappelés ci-dessus mais qui, en outre, permet d'assurer la perforation de la pellicule sans retrait préalable du capuchon et, en conséquence, sans que cette pellicule puisse être souillée par un objet quelconque.The invention relates to an improved closure device which has all the qualities of the devices mentioned above but which, moreover, makes it possible to ensure the perforation of the film without prior removal of the cap and, consequently, without this film being able to be soiled by any object.

En outre, le dispositif de l'invention empêche que des déchets de la pellicule puissent tomber dans le récipient et cela bien que la pellicule laisse libre la presque totalité de la surface du goulot du récipient lorsqu'elle est perforée.In addition, the device of the invention prevents waste of the film from falling into the container, even though the film leaves almost the entire surface of the neck of the container when it is perforated.

De plus, l'invention par sa mise en oeuvre dans un mode de réalisation préféré permet d'assurer une double inviolabilité c'est-à-dire que l'utilisateur du récipient comportant le dispositif de l'invention est assuré qu'il n'a pas été possible d'accéder à la pellicule de protection tant qu'il n'a pas, lui-même, retiré un élément d'inviolabilité.In addition, the invention by its implementation in a preferred embodiment ensures double inviolability, that is to say that the user of the container comprising the device of the invention is assured that there It was not possible to access the protective film until he himself had removed an element of inviolability.

Le dispositif de fermeture de l'invention présente, en outre, l'avantage de permettre l'utilisation de capsules de types extrêmement divers, c'est-à-dire des capsules pouvant être ouvertes ou fermées soit par un mouvement de pivotement, de basculement ou de coulissement. En d'autres termes, la capsule pouvant être utilisée peut, dans tous les cas, être celle la mieux adaptée à la matière que contient le récipient.The closure device of the invention has the further advantage of allowing the use of capsules of extremely diverse types, that is to say capsules which can be opened or closed either by a pivoting movement, tilting or sliding. In other words, the capsule that can be used can, in all cases, be that which is best suited to the material that the container contains.

Une réalisation particulière de l'invention permet le stockage de façon éventuellement stérile et à l'abri de l'air de deux produits différents pouvant être mélangés tout en les maintenant stériles et à l'abri de l'air jusqu'au moment où ils doivent être utilisés.A particular embodiment of the invention allows the storage, optionally sterile and protected from air, of two different products which can be mixed while keeping them sterile and protected from air until they are should be used.

A ce sujet, on connaît le document US-A-4 583 365 qui décrit des moyens permettant de perforer une membrane mais ces moyens, ainsi que cela ressort de la description, notamment à la colonne 4 à partir de la ligne 17, font que des parties de ladite membrane peuvent tomber dans le récipient, ce qui constitue un inconvénient pouvant être grave.In this regard, document US-A-4 583 365 is known which describes means making it possible to perforate a membrane, but these means, as appears from the description, in particular in column 4 from line 17, mean that parts of said membrane may fall into the container, which constitutes a drawback which can be serious.

Au contraire, la présente Invention fait que l'organe perforateur est prévu pour rabattre complètement la membrane ou pellicule contre la paroi du goulot sans qu'il y ait de chute de parcelles de pellicule dans le récipient.On the contrary, the present invention means that the perforating member is designed to completely fold the membrane or film against the wall of the neck without there being any drop of film plots in the container.

Ainsi conformément à l'invention, le dispositif de fermeture pour récipients dans lequel un capuchon est mis en place sur une extrémité du récipient formant un goulot, ledit capuchon comportant une partie d'emboîtement du récipient et une partie comprenant des moyens d'ouverture et de fermeture, une pellicule étant scellée à la partie formant le goulot du récipient, un organe perforateur étant disposé à proximité de la pellicule et porté par une cloison du capuchon, ladite cloison présentant au moins un trou et l'organe perforateur étant prévu pour rabattre cette pellicule vers la paroi du goulot, des moyens faisant que le perforateur peut occuper une première position pour laquelle il ne peut pas agir sur la pellicule et au moins une seconde position dans laquelle ladite pellicule est rompue, est caractérisé en ce que l'organe perforateur présente une trajectoire hélicoïdale dans le sens transversal avec un point de départ de la perforation vers le centre. la trajectoire de la lame perforatrice étant dirigée vers l'extérieur, lesdits moyens faisant que, dans ladite seconde position, la pellicule est rabattue contre la paroi du goulot en formant un manchon interne laissant libre la communication entre le récipient et l'intérieur du capuchon.Thus according to the invention, the closure device for containers in which a cap is placed on one end of the container forming a neck, said cap comprising a part for fitting the container and a part comprising means for opening and closure, a film being sealed to the portion forming the neck of the container, a perforating member being arranged near the film and carried by a partition of the cap, said partition having at least one hole and the perforating member being provided for folding down this film towards the wall of the neck, means causing the perforator to occupy a first position for which it cannot act on the film and at least a second position in which said film is ruptured, is characterized in that the member perforator has a helical trajectory in the transverse direction with a starting point of the perforation towards the center. the trajectory of the perforating blade being directed outwards, said means causing that, in said second position, the film is folded back against the wall of the neck by forming an internal sleeve leaving free communication between the container and the inside of the cap .

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, aux dessins annexés.Embodiments of the object of the invention are shown, by way of nonlimiting examples, in the accompanying drawings.

La fig. 1 est une coupe-élévation partielle du dispositif de fermeture du récipient objet de l'invention.Fig. 1 is a partial sectional elevation of the container closure device object of the invention.

La fig. 2 est une coupe schématique vue sensiblement selon la ligne II-II de la fig. 1.Fig. 2 is a schematic section seen substantially along line II-II of FIG. 1.

La fig. 3 est une coupe analogue à la fig. 1 illustrant le dispositif de fermeture en position d'utilisation.Fig. 3 is a section similar to FIG. 1 illustrating the closure device in the use position.

La fig. 4 est une coupe analogue à la fig. 2 d'une variante.Fig. 4 is a section similar to FIG. 2 of a variant.

La fig. 5 est une coupe vue suivant la ligne V-V de la fig. 4.Fig. 5 is a section seen along line VV of FIG. 4.

La fig. 6 est une coupe analogue à la fig. 1 illustrant un développement de l'invention. La fig. 7 est une coupe-élévation d'une variante de réalisation du dispositif de fermeture, objet de l'invention.Fig. 6 is a section similar to FIG. 1 illustrating a development of the invention. Fig. 7 is a sectional elevation of an alternative embodiment of the closure device, object of the invention.

Au dessin, 1 désigne un récipient pouvant contenir un produit quelconque par exemple un produit alimentaire, un produit cosmétique, un produit médicamenteux, un produit chimique , etc.In the drawing, 1 denotes a container which may contain any product, for example a food product, a cosmetic product, a medicinal product, a chemical product, etc.

Ces produits peuvent être liquides, pulvérulents ou se présenter sous la forme de paillettes ou de granulés.These products can be liquid, powdery or come in the form of flakes or granules.

Le récipient 1 comporte un goulot 2 qui est représenté de plus petite section que le reste du récipient mais qui pourrait aussi présenter la même dimension que le corps de ce récipient.The container 1 has a neck 2 which is shown of smaller section than the rest of the container but which could also have the same dimension as the body of this container.

Pour protéger la matière contenue dans le récipient le goulot 2 est fermé sur son dessus par une pellicule 3 qui est scellée. La pellicule 3 peut être en aluminium, en matière synthétique en papier imprégné ou non ou en une autre matière et elle est mise en place par un procédé quelconque connue dans la technique après avoir éventuellement fait le vide à l'intérieur dudit récipient. Outre, la pellicule 3, le dispositif de fermeture comporte un capuchon désigné dans son ensemble par 4, ce capuchon ayant une paroi latérale entourant le goulot 2 auquel il est relié par des moyens de liaison notamment des filets de vis 5 ou des barrettes de clipsage permettant au capuchon 4 d'occuper au moins deux positions par rapport au goulot 2, à savoir une position de fermeture et une position d'ouverture du récipient.To protect the material contained in the container, the neck 2 is closed on its top by a film 3 which is sealed. The film 3 may be made of aluminum, of synthetic material of impregnated or non-impregnated paper or of another material and it is put in place by any process known in the art after having optionally evacuated inside said container. In addition, the film 3, the closure device comprises a cap designated as a whole by 4, this cap having a side wall surrounding the neck 2 to which it is connected by means of connection in particular screw threads 5 or clipping bars allowing the cap 4 to occupy at least two positions relative to the neck 2, namely a closed position and an open position of the container.

Le capuchon 4 est muni à sa base d'une bande 6 détachable reliée audit capuchon par un élément de rupture 7.The cap 4 is provided at its base with a detachable strip 6 connected to said cap by a breaking element 7.

La bande détachable 6 vient en butée contre une partie saillante du récipient 1, par exemple, contre la partie haute du corps de celui-ci et cette bande détermine l'une des positions que peut occuper le capuchon par rapport audit récipient, c'est-à-dire que, lorsque la bande détachable 6 est en butée, les moyens de liaison 5 existant entre le capuchon et le récipient sont en prise les uns avec les autres.The detachable strip 6 abuts against a projecting part of the container 1, for example, against the upper part of the body thereof and this strip determines one of the positions that the cap can occupy relative to said container, that is that is, when the detachable strip 6 is in abutment, the connecting means 5 existing between the cap and the container are engaged with each other.

Le capuchon 4 est muni intérieurement d'une cloison 8 présentant au moins un trou 9. La cloison 8 relie le corps du capuchon à un organe perforateur 10 qui, dans la réalisation des fig. 1 et 2, se présente sous la forme d'une lame sensiblement en forme de S dont la largeur 1 (fig. 2) est, par exemple sensiblement égale au diamètre interne du goulot 2. Comme l'illustrent les fig. 1 et 3, l'organe perforateur 10 présente une pointe 11 et des bords inclinés 12, 13. Les dimensions de l'organe perforateur 10 sont choisies pour que celui-ci se trouve à faible distance voire en contact avec le dessus de la pellicule scellée 3 lorsque le capuchon 4 est en place sur le récipient 1 c'est-à-dire lorsque la bande détachable 6 est en butée comme montré par la fig. 1.The cap 4 is internally provided with a partition 8 having at least one hole 9. The partition 8 connects the body of the cap to a perforating member 10 which, in the embodiment of FIGS. 1 and 2, is in the form of a substantially S-shaped blade whose width 1 (FIG. 2) is, for example substantially equal to the internal diameter of the neck 2. As illustrated in FIGS. 1 and 3, the perforating member 10 has a point 11 and inclined edges 12, 13. The dimensions of the perforating member 10 are chosen so that it is at a short distance or even in contact with the top of the film sealed 3 when the cap 4 is in place on the container 1, that is to say when the detachable strip 6 is in abutment as shown in FIG. 1.

La partie supérieure 4a du capuchon 4 peut être réalisée d'une manière quelconque connue dans la technique, par exemple comporter un couvercle 14 avec des organes à ouverture commandée par un mouvement de rotation ou de coulissement ou de pivotement. Cette partie du capuchon 4 n'étant pas comprise dans l'objet de l'invention, n'est pas décrite plus en détail et est, à cette fin, illustrée en traits mixtes.The upper part 4a of the cap 4 can be produced in any manner known in the art, for example comprising a cover 14 with members with opening controlled by a rotation or sliding or pivoting movement. This part of the cap 4 is not included in the object of the invention, is not described in more detail and is, for this purpose, illustrated in phantom.

Lorsque l'on désire utiliser la matière contenue dans le récipient 1, ou une partie de cette matière, on détache la bande 6 en utilisant, par exemple, une languette de préhension 15 qu'elle peut comporter et on déplace le capuchon par rapport au récipient pour que la base du capuchon vienne à nouveau en butée comme l'illustre la fig. 3. Le déplacement est produit par vissage si les moyens de liaison 5 sont des filets de vis ou par une simple poussée si les moyens sont des barrettes clipsables ou analogues.When it is desired to use the material contained in the container 1, or a part of this material, the strip 6 is detached by using, for example, a gripping tab 15 which it may comprise and the cap is moved relative to the container so that the base of the cap again comes to a stop as illustrated in fig. 3. The displacement is produced by screwing if the connecting means 5 are screw threads or by a simple push if the means are clip-on bars or the like.

Le mouvement conféré au capuchon a pour effet que la pointe 11 perfore la pellicule 3 puis que les côtés inclinés 12, 13 rabattent la pellicule 3 contre le flanc du goulot. En faisant tourner le capuchon 4 par rapport au goulot, ce qui est obtenu automatiquement lorsque les moyens de liaison sont des filets de vis, on obtient une ouverture maximale de la pellicule 3 sans qu'elle tombe tout ou en partie dans le récipient 1. La matière contenue dans le récipient 1 peut ensuite être utilisée en ouvrant le couvercle 14 ou au moyen des fermetures d'autres natures que comporte le capuchon 4.The movement imparted to the cap has the effect that the tip 11 punctures the film 3 then the inclined sides 12, 13 fold the film 3 against the side of the neck. By rotating the cap 4 relative to the neck, which is obtained automatically when the connecting means are screw threads, a maximum opening of the film 3 is obtained without it falling entirely or partially into the container 1. The material contained in the container 1 can then be used by opening the cover 14 or by means of closures of other kinds which the cap 4 comprises.

L'organe perforateur 10 peut être constitué de nombreuses façons différentes ; les fig. 4 et 5 montrent, par exemple, qu'il peut être constitué par des lames 16, par exemple de forme hélicoïdale. Dans ce cas l'ouverture complète de la pellicule 3 est produite par rotation d'environ un tour du capuchon 4. L'organe perforateur peut aussi être formé directement depuis la paroi interne du capuchon 4 sans qu'il soit prévu une cloison 8 qui a été représentée seulement pour faciliter la compréhension du fonctionnement. L'organe perforateur peut aussi être partiellement annulaire.The perforating member 10 can be made up in many different ways; fig. 4 and 5 show, for example, that it can be constituted by blades 16, for example of helical shape. In this case, the complete opening of the film 3 is produced by rotation of about one turn of the cap 4. The perforating member can also be formed directly from the internal wall of the cap 4 without a partition 8 being provided which has been shown only to facilitate the understanding of the operation. The perforating member may also be partially annular.

Il est avantageux que le capuchon et l'organe perforateur ne créent pas une perte de charge pouvant être nuisible dans certaines utilisations et pour cela sa forme et ses dimensions sont déterminées en conséquence par l'homme du métier.It is advantageous that the cap and the perforating member do not create a pressure drop which may be harmful in certain uses and for this its shape and its dimensions are determined accordingly by the person skilled in the art.

La fig. 6 illustre un développement de l'invention selon lequel la bande détachable alors montrée en 6a est insérée dans une partie de retenue 17 du flanc du récipient par exemple dans une gorge de celui-ci. Dans ce cas, la bande détachable 6a constitue, en outre, un élément d'inviolabilité en forme de bague empêchant tout retrait du capuchon 4 et empêchant, par conséquent, tout accès à la pellicule 3 tant que la bande détachable et d'inviolabilité 6a n'a pas été retirée.Fig. 6 illustrates a development of the invention according to which the detachable strip then shown in 6 a is inserted into a retaining part 17 of the side of the container, for example in a groove of the latter. In this case, the detachable strip 6 a constitutes, in addition, a tamper-evident element in the form of a ring preventing any removal of the cap 4 and consequently preventing any access to the film 3 while the detachable and tamper-proof strip 6 a has not been withdrawn.

A la fig. 7, on a représenté un récipient 1 semblable à celui des figures 1 à 6 et qui comprend en outre un récipient auxiliaire 17, ce récipient formant, à partir de son fond, une embase 18 dont la forme est analogue à celle du goulot 2 du récipient 1 et qui joue ainsi à cet effet le rôle du goulot 2. L'embase 18 comporte un filetage 19 de pas opposé à celui du filetage 5 et elle entoure une ouverture 20 prévue dans le fond du récipient 17. L'embase 18 est fermée par une pellicule 21 analogue à la pellicule 3 décrite ci-dessus.In fig. 7, there is shown a container 1 similar to that of FIGS. 1 to 6 and which further comprises an auxiliary container 17, this container forming, from its bottom, a base 18 whose shape is similar to that of the neck 2 of the container 1 and which thus plays for this purpose the role of the neck 2. The base 18 has a thread 19 of pitch opposite to that of the thread 5 and it surrounds an opening 20 provided in the bottom of the container 17. The base 18 is closed by a film 21 similar to the film 3 described above.

Les filetages 5 et 19 des récipients 1 et 17 sont reliés entre eux par une couronne taraudée 22 qui n'est cependant pas vissée complètement sur lesdits filetages et qui constitue ainsi un capuchon analogue au capuchon 4 des figures précédentes, tant pour le récipient 1 que pour le récipient 15. La couronne 22 est munie, à sa partie médiane, d'un voile 23 qui forme, ou auquel, est rapporté un perforateur 24.The threads 5 and 19 of the receptacles 1 and 17 are connected together by a threaded ring 22 which is not, however, completely screwed onto the said threads and which thus constitutes a cap similar to the cap 4 of the preceding figures, both for the receptacle 1 and for the container 15. The crown 22 is provided, at its central part, with a veil 23 which forms, or to which, a perforator 24 is attached.

Comme l'illustre le dessin, le perforateur 24 comporte deux parties ou lames tranchantes opposées 25 et 26 tournées respectivement vers les pellicules 21 et 3.As illustrated in the drawing, the perforator 24 has two opposite cutting parts or blades 25 and 26 facing the films 21 and 3 respectively.

Le perforateur 24 est creux.The perforator 24 is hollow.

La couronne 22 à laquelle est relié le perforateur 24 est maintenue par un organe d'immobilisation qui, dans l'exemple de réalisation représenté, est constitué par un cavalier 27 réalisé en matière déformable élastiquement et qui est inséré entre les récipients 1 et 17 pour former une entretoise.The ring 22 to which the perforator 24 is connected is held by an immobilizing member which, in the illustrated embodiment, consists of a jumper 27 made of elastically deformable material and which is inserted between the containers 1 and 17 for form a spacer.

Le cavalier 27 est appliqué contre la paroi externe de la couronne 22,et la fig. 7 montre que ledit cavalier comporte, à ses extrémités, des épaississements 27a et 27b qui coiffent la couronne 22 de part et d'autre en prenant appui respectivement contre le récipient 1 et le récipient auxiliaire 17 en bloquant ainsi cette couronne dans la position représentée.The jumper 27 is applied against the outer wall of the crown 22, and FIG. 7 shows that said jumper has, at its ends, thickenings 27a and 27b which cover the crown 22 on either side by pressing respectively against the container 1 and the auxiliary container 17 thereby blocking this crown in the position shown.

L'organe d'immobilisation pourrait être constitué d'autres façons que par le cavalier 27, et, par example, au moyen de deux anneaux en matière souple et pouvant être brisés, lesdits anneaux occupant la position des épaississements 27a et 27b.The immobilization member could be constituted in other ways than by the rider 27, and, for example, by means of two rings of flexible material which can be broken, said rings occupying the position of the thickenings 27a and 27b.

Lorsque des anneaux sont utilisés en tant qu'organes d'immobilisation, ils sont mis en place avant le montage de la couronne 22 qui est vissée jusqu'à venir en contact avec chacun des anneaux.When rings are used as immobilizing members, they are put in place before mounting the crown 22 which is screwed until it comes into contact with each of the rings.

Outre ce qui précède et comme l'illustre la fig. 7, il est avantageux que le voile 23 soit muni, entre le perforateur 24 et la couronne 22, d'un manchon 28 qui est cylindrique et qui est engagé dans des saignées annulaires 29 et 30 prévues dans l'épaisseur de l'embase 18, d'une part, et dans l'épaisseur du goulot 2, d'autre part. Le manchon 28 relie ainsi le récipient 1 au récipient auxiliaire 17.In addition to the above and as illustrated in fig. 7, it is advantageous for the web 23 to be provided, between the perforator 24 and the crown 22, with a sleeve 28 which is cylindrical and which is engaged in annular grooves 29 and 30 provided in the thickness of the base 18 , on the one hand, and in the thickness of the neck 2, on the other hand. The sleeve 28 thus connects the container 1 to the auxiliary container 17.

En choisissant convenablement la matière constitutive du goulot 2,de l'embase 18 et du manchon 28, il est possible d'assurer une très bonne étanchéité à la chambre 31 délimitée par les pellicules 3 et 21.By suitably choosing the material constituting the neck 2, the base 18 and the sleeve 28, it is possible to ensure very good sealing of the chamber 31 delimited by the films 3 and 21.

Le récipient auxiliaire 17 comporte, par ailleurs, un goulot 32 sur lequel est monté un dispositif de fermeture 33 par exemple un embout à couper présentant une zone de moindre résistance 31 comme cela est représenté à titre d'exemple. Tout autre dispositif de fermeture désiré connu dans la technique pourrait être utilisé.The auxiliary container 17 also comprises a neck 32 on which is mounted a closing device 33, for example a tip to be cut having a zone of least resistance 31 as shown by way of example. Any other desired closure known in the art could be used.

Comme cela ressort de ce qui précède, lorsqu'on désire utiliser les produits contenues dans les récipients 1 et 17, on retire le cavalier 2, 7 ou autre organe ou organes d'immobilisation, ce qui libère la couronne 22.As is apparent from the above, when it is desired to use the products contained in containers 1 and 17, the jumper 2, 7 or other immobilizing member or members is removed, which releases the crown 22.

En faisant tourner la couronne 22, cela a pour effet d'entraîner en rotation d'une même mesure le perforateur 21 qui y est relié par le voile 23. En même temps, la couronne 22 qui est vissée sur les filetages 5 et 19 des récipients 1 et 17 rapproche ceux-ci l'un de l'autre de sorte que les parties tranchantes 25 et 26 du perforateur 21 découpent les pellicules 3 et 21.By rotating the crown 22, this has the effect of causing the perforator 21 which is connected to it by the web 23 to rotate in the same measure. At the same time, the crown 22 which is screwed onto the threads 5 and 19 of the containers 1 and 17 bring these closer to one another so that the cutting parts 25 and 26 of the perforator 21 cut the films 3 and 21.

L'intérieur des récipients 1 et 17 étant mis en communication cela permet de mélanger les produits qui se trouvaient dans chacun d'eux. Le manchon 28 assure une parfaite étanchéité entre l'intérieur des deux récipients puisque, en fin de découpage des pellicules 3 et 21, ce manchon peut pénétrer davantage dans les saignées 29 et 30.The interior of the containers 1 and 17 being placed in communication this makes it possible to mix the products which were in each of them. The sleeve 28 ensures a perfect seal between the interior of the two containers since, at the end of the cutting of the films 3 and 21, this sleeve can penetrate further into the grooves 29 and 30.

Il est possible avantageusement d'agiter les deux flacons réunis pour mélanger parfaitement les produits entre eux.It is advantageously possible to shake the two bottles together to mix the products perfectly together.

Finalement, le dispositif de fermeture 33 est ouvert, ce qui permet d'utiliser les produits mélangés.Finally, the closing device 33 is opened, which makes it possible to use the mixed products.

Les récipients 1 et 17 peuvent être fabriqués dans de nombreuses matières différentes, par exemple en polychlorure de vinyle ou polyéthylène ou même en verre. L'un des flacons peut être fabriqué dans une matière et l'autre dans une matière différente.Containers 1 and 17 can be made of many different materials, for example polyvinyl chloride or polyethylene or even glass. One of the bottles can be made of one material and the other of a different material.

Les parties tranchantes 25 et 26 du perforateur peuvent être en même matière que l'ensemble perforateur-voile-manchon et couronne qui est avantageusement fabriqué en une seule pièce par injection ou un autre moyen connu dans la technique.The cutting parts 25 and 26 of the perforator can be made of the same material as the perforator-veil-sleeve and crown assembly which is advantageously made in one piece by injection or another means known in the art.

Les parties tranchantes 25, 26 peuvent, le cas échéant, être dentelées pour faciliter la découpe des pellicules 3 et 21.The cutting parts 25, 26 can, if necessary, be serrated to facilitate the cutting of the films 3 and 21.

On notera en outre que, lorsqu'il n'est pas prévu de manchon 28, le dispositif peut relier deux récipients ordinaires par leur goulot respectif.It will also be noted that, when a sleeve 28 is not provided, the device can connect two ordinary containers by their respective necks.
