Description

Diverses préparations chimiques doivent être élaborées aussi tard que possible avant leur emploi car leurs propriétés s'altèrent progressivement sous l'effet de phénomènes physiques ou chimiques variés, séchage, oxydation, réactions mutuelles, polymérisation... Ce peut être le cas de colles ou tous autres produits à conservation limitée, et en particulier des médicaments dits extemporanés.Various chemical preparations must be prepared as late as possible before their use because their properties gradually deteriorate under the effect of various physical or chemical phenomena, drying, oxidation, mutual reactions, polymerization ... This may be the case for adhesives or all other products with limited storage, and in particular so-called extemporaneous medicines.

Pour obtenir le mélange intime de leurs éléments, le plus commode, lorsque c'est possible, est de répartir ces derniers en deux composants dont l'un sera liquide et pourra en particulier comprendre un solvant, l'autre pouvant alors se présenter sous des formes diverses, au besoin en phase solide mais souvent dispersée, c'est-à-dire en poudre.To obtain the intimate mixture of their elements, the most convenient, when possible, is to distribute the latter into two components, one of which will be liquid and may in particular comprise a solvent, the other then being able to be present in various forms, if necessary in solid phase but often dispersed, that is to say in powder.

Le brevet US-A-3608782 propose ainsi de placer les deux composants dans deux tubes souples enfermés dans un boîtier possédant deux compartiments jumeaux de mise sous pression externe dont le premier seul au départ se trouve empli d'un gaz vecteur. Une tête vient s'enfoncer sur ce boîtier, équipée de trois trocards dont les deux premiers, reliés entre eux pour créer un pont, perforent alors deux opercules pour permettre le transfert du premier composant du premier tube vers le second, le troisième venant mettre à l'air libre le second compartiment; puis elle est enlevée et réenfoncée dans une position différente pour mettre sous pression le second compartiment en servant de pont entre lui et le premier tandis que le troisième trocard met à l'air libre le tube correspondant pour permettre l'expulsion du produit. Les opercules sont censés se refermer lorsqu'on enlève la tête.Patent US-A-3608782 thus proposes to place the two components in two flexible tubes enclosed in a housing having two twin compartments for external pressurization, the first of which alone at the start is filled with a carrier gas. A head sinks into this housing, equipped with three trocards, the first two of which, linked together to create a bridge, then perforate two lids to allow the transfer of the first component from the first tube to the second, the third coming to put the second compartment in the open air; then it is removed and reinserted in a different position to pressurize the second compartment by serving as a bridge between it and the first while the third trocar puts the corresponding tube in the open air to allow the expulsion of the product. The gates are supposed to close when the head is removed.

Cette solution paraît compliquée, peu commode et incertaine.This solution seems complicated, inconvenient and uncertain.

Il est connu d'autre part de fournir divers produits, parfums, insecticides ou autres, sous forme d'aérosols obtenus par détente d'un gaz ou d'un liquide support, azote, butane, hydrocarbure fluoré... qui permet de les délivrer, même à faibles doses, en pulvérisation très fine; ils sont alors commercialisés en bombes ou flacons dits "aérosols", équipés de valves normalisées, généralement miniatures: leur clapet possède une tige de commande tubulaire qui sert de gicleur d'évacuation, et recevra une tête à poussoir de structure variable, qui portera usuellement la buse de pulvérisation voulue. C'est précisément le cas de divers médicaments, le plus souvent destinés au traitement des voies respiratoires, qu'elles soient bucco-pharyngées ou pulmonaires.It is also known to supply various products, perfumes, insecticides or other, in the form of aerosols obtained by expansion of a gas or a support liquid, nitrogen, butane, fluorinated hydrocarbon ... which allows them deliver, even at low doses, in very fine spray; they are then sold in bombs or bottles called "aerosols", equipped with standardized valves, generally miniature: their valve has a tubular control rod which serves as an evacuation nozzle, and will receive a pusher head of variable structure, which will usually carry the desired spray nozzle. This is precisely the case with various drugs, most often intended for the treatment of the respiratory tract, whether buccopharyngeal or pulmonary.

L'invention a pour objet de fournir un conditionnement apte au stockage et au transport puis au mélange des composants de produits évolutifs, et à la distribution de ces derniers, ce conditionnement permettant notamment de présenter sous une forme commode des médicaments à préparation extemporanée.The object of the invention is to provide a packaging suitable for storage and transport and then for mixing the components of evolving products, and for distributing the latter, this packaging. allowing in particular to present in a convenient form drugs with extemporaneous preparation.

Le conditionnement en question sera essentiellement constitué d'un ensemble de deux récipients rigides fermés par des valves "aérosol" et d'un pont de raccordement capable de relier rigidement et de façon étanche leurs deux gicleurs.The packaging in question will essentially consist of a set of two rigid containers closed by "aerosol" valves and a connection bridge capable of rigidly and sealingly connecting their two nozzles.

L'un des récipients renfermera, en milieu liquide, sous une pression gazeuse interne suffisamment élevée, le premier composant, mis par exemple en solution avec le gaz vecteur; l'autre renfermera le second composant, sous une pression gazeuse interne faible d'un gaz inerte, au besoin sous un certain vide. Le pont constituera un robinet "à trois voies", l'une d'entrée vers le premier récipient, ouverte par l'organe mobile de ce robinet lors du transfert mais ensuite neutralisée, la deuxième vers le second récipient, permanente sous réserve de l'ouverture de la valve de celui-ci, la troisième de sortie vers l'extérieur,ouverte par l'organe mobile lors de la seule distribution du produit final.One of the receptacles will contain, in a liquid medium, under a sufficiently high internal gas pressure, the first component, dissolved for example with the carrier gas; the other will contain the second component, under a low internal gas pressure of an inert gas, if necessary under a certain vacuum. The bridge will constitute a "three-way" tap, one for entry to the first container, opened by the movable member of this tap during transfer but then neutralized, the second for the second container, permanent subject to opening of the valve thereof, the third outlet to the outside, opened by the movable member during the sole distribution of the final product.

L'utilisation devant se faire en deux temps, l'un de mélange, le suivant de distribution, le pont permettra d'abord de mettre les deux récipients en communication en pressant simultanément sur les deux valves ce qui provoquera le transfert du premier composant mêlé à une partie du gaz vecteur vers le second récipient avec brassage jusqu'à égalisation des pressions; puis, ouvrant une voie vers l'extérieur, on sera à même, au besoin après un certain temps d'attente voire de stockage, d'expulser à partir de ce récipient, selon son mode de fonctionnement normal, le produit de mélange ou de réaction obtenu, pour en permettre l'utilisation finale.The use having to be done in two stages, one of mixing, the next of distribution, the bridge will allow first to put the two containers in communication by pressing simultaneously on the two valves which will cause the transfer of the first mixed component part of the carrier gas to the second container with stirring until the pressures are equalized; then, opening a way to the outside, we will be able, if necessary after a certain waiting time or even storage, to expel from this container, according to its normal operating mode, the product of mixing or reaction obtained, to allow end use.

Pour éviter qu'une erreur de manipulation ne provoque une mauvaise utilisation, il vaut mieux employer deux récipients semblables, placés côte à côte. Utilement, une dissymétrie externe, au moins visuelle mais de préférence structurelle, évitera toute erreur à l'assemblage.To prevent mishandling from causing misuse, it is best to use two similar containers, placed side by side. Usefully, an external asymmetry, at least visual but preferably structural, will avoid any assembly error.

D'autres caractéristiques et avantages ressortiront de la description détaillée de deux exemples, donnée ci-dessous en référence aux dessins, qui montrent ces conditionnements avec:

  • ― figure 1: une coupe longitudinale d'un conditionnement avec pont à trois voies,
  • ― figure 2: une coupe d'un conditionnement analogue avec pont démontable,
  • ― figure 3: une coupe transversale de ce conditionnement, selon 3-3 de la figure 2.
Other characteristics and advantages will emerge from the detailed description of two examples, given below with reference to the drawings, which show these packaging with:
  • - Figure 1: a longitudinal section of a package with three-way bridge,
  • - Figure 2: a section of a similar packaging with removable bridge,
  • - Figure 3: a cross section of this packaging, according to 3-3 of Figure 2.

Le pont représenté sur la figure 1 a la structure d'un simple robinet à trois voies: son corps 1 forme un boisseau porteur de deux bouches jumelles 2a et 2b dont les canaux juxtaposés 3a et 3b ont leurs axes parallèles. Son alésage reçoit une clef 4 qui porte, schématiquement représentée, une buse de pulvérisation 5; ici, la clef est traversante et c'est son bouton de manoeuvre 6 à l'opposé du vissage de la buse qui sert à la retenir.The bridge shown in Figure 1 has the structure of a simple three-way stopcock: its body 1 forms a plug carrying two twin mouths 2 a and 2 b whose juxtaposed channels 3 a and 3 b have their axes parallel. Its bore receives a key 4 which carries, schematically shown, a spray nozzle 5; here, the key is through and it is its operating button 6 opposite the screwing of the nozzle which serves to retain it.

Les sièges de chacune des bouches 2a et 2b s'adaptent sur le gicleur normalisé des valves 7a et 7b, à tube de prise, de deux flacons pour aérosols 8a et 8b: le flacon 8a renferme le premier composant et son gaz vecteur; le flacon 8b renferme le second composant. Pour que les fonds de ces flacons puissent reposer sur un même appui plan en dépit de leur différence de hauteur, liée au fait que le premier possède ici une moindre capacité, une longueur différente a été donnée aux deux embouts.The seats of each of the mouths 2 a and 2 b fit on the standardized nozzle of the valves 7 a and 7 b , with intake tube, of two aerosol bottles 8 a and 8 b : the bottle 8 a contains the first component and its carrier gas; the bottle 8b contains the second component. So that the bottoms of these bottles can rest on the same flat support despite their difference in height, linked to the fact that the first has a lower capacity here, a different length has been given to the two nozzles.

La clef 4 possède une saignée longitudinale de transfert 10a et un canal de distribution 10b qui débouche par un orifice latéral sur une autre génératrice; l'une, dans la position représentée sur la figure, relie les orifices internes des canaux des deux bouches 2a et 2b; si l'on tourne la clef d'un angle suffisant, c'est l'autre qui débouche à son tour sur le seul orifice de la bouche 2b. Pour repérer ces deux positions, on peut prévoir deux butées ou deux crans d'arrêt à effet de cames, par exemple en 6a entre la jupe du bouton de manoeuvre et le corps du boisseau.The key 4 has a longitudinal transfer groove 10 a and a distribution channel 10 b which opens out through a lateral orifice on another generator; one, in the position shown in the figure, connects the internal orifices of the channels of the two mouths 2 a and 2 b ; if one turns the key by a sufficient angle, it is the other which in turn leads to the only orifice of the mouth 2 b . To identify these two positions, it is possible to provide two stops or two cam locking stops, for example at 6 a between the skirt of the operating button and the body of the plug.

Le corps 1 sert de poussoir et l'opérateur, en l'enfonçant vers les flacons, fait s'ouvrir ensemble les deux valves: dans un premier temps, la clef 4 se trouvant dans la position représentée, le gaz vecteur transfère la majeure partie du contenu du flacon 8a vers le flacon 8b à travers la saignée 10a; après inversion de la position de la clef, une nouvelle pression libère au contraire le contenu du flacon 8b vers l'extérieur à travers le canal 10b et la buse de pulvérisation 5.The body 1 serves as a pusher and the operator, by pushing it towards the bottles, causes the two valves to open together: firstly, the key 4 being in the position shown, the carrier gas transfers most of it from the contents of the bottle 8 a to the bottle 8 b through the groove 10 a ; after reversing the position of the key, a new pressure on the contrary releases the contents of the bottle 8b to the outside through the channel 10b and the spray nozzle 5.

De nombreuses variantes sont également possibles, utilisant par exemple une douille tournante montée, en rotation ou même à mouvement hélicoïdal pour obtenir une meilleure étanchéité, aussi bien dans l'axe du raccordement que sur celui de la valve 7b du second flacon.Many variants are also possible, using for example a rotating bushing mounted, in rotation or even with a helical movement to obtain a better seal, both in the axis of the connection and on that of the valve 7b of the second bottle.

Le pont utilisé dans le cas que représentent les figures 2 et 3 forme encore un robinet à trois voies. Il comprend un tube de jonction 11, qui s'emboîte à force sur chacun des orifices de sortie latéraux de deux têtes jumelles 12a et 12b pour se raccorder à angle droit à leurs canaux internes 13a, 13b, en traversant l'alésage d'un manchon 14 porteur d'une buse telle que la buse 15a de la canule 15. Des rampes 16a, 16b maintiennent parallèles, côte à côte, les axes des têtes 12a et 12b. Sur leurs sièges s'adaptent les valves 17a et 17b, sans tube de prise, de deux cartouches complémentaires 18a et 18b, dont la première est sous pression, enfermant ces cartouches dans un boîtier 19 dont un rebord 19a retient celui, complémentaire, de chacune des deux têtes 12a, 12b; c'est ici un décalage dans le fond 19b du boîtier 19 qui compense la différence de longueur des deux cartouches.The bridge used in the case shown in Figures 2 and 3 still forms a three-way valve. It comprises a junction tube 11, which is forced into each of the lateral outlet orifices of two twin heads 12 a and 12 b to connect at right angles to their internal channels 13 a , 13 b , crossing the bore of a sleeve 14 carrying a nozzle such as the nozzle 15 a of the cannula 15. Ramps 16 a , 16b keep the axes of heads 12 a and 12 b parallel, side by side. On their seats are adapted the valves 17 a and 17 b , without intake tube, of two complementary cartridges 18 a and 18 b , the first of which is under pressure, enclosing these cartridges in a casing 19 of which a flange 19 has retained that , complementary, of each of the two heads 12 a , 12 b ; here is an offset in the bottom 19b of the housing 19 which compensates for the difference in length of the two cartridges.

La valve 17b est ici une valve doseuse: il en existe des modèles courants qui, sur le flacon 18b, se préteront au fonctionnement décrit.The valve 17 b is here a metering valve: there are current models, on the bottle 18 b, will lend themselves to the operation described.

Le canal interne du tube 11 est divisé par un voile médian en deux biefs qui débouchent latéralement par deux orifices voisins 11a et 11b, représentés ici dans le même plan diamétral. Le manchon 14, qui peut tourner à frottement doux sur le tube 11, porte deux évidements internes l'un, 20a, longitudinal, capable de mettre en communication les deux orifices, l'autre, 20b, en L ou oblique transversalement en arrière du plan de figure, capable de relier l'orifice 11b à celui 15b de la canule 15.The internal channel of the tube 11 is divided by a central web into two bays which open laterally by two adjacent holes 11 a and 11 b, shown here in the same diametral plane. The sleeve 14, which can rotate with gentle friction on the tube 11, carries two internal recesses one, 20 a , longitudinal, capable of bringing the two orifices into communication, the other, 20 b , in L or oblique transversely in rear of the plane of the figure, capable of connecting the orifice 11 b to that of the cannula 15 b 15.

Au repos, déportée ici transversalement par rapport à l'axe du tube, la canule s'efface dans un dégagement 21 pratiqué entre les deux cartouches sur le côté du boîtier 19; l'évidement 20a ouvre alors un passage entre les deux valves 17a et 17b. Par rotation il est possible de la redresser, par exemple jusqu'à mise en butée sur l'une des rampes 22a, 22b: seule alors, par le jeu de l'évidement 20b, la valve 17b est reliée à l'extérieur.At rest, offset here transversely to the axis of the tube, the cannula disappears in a clearance 21 made between the two cartridges on the side of the housing 19; the recess 20 a then opens a passage between the two valves 17 a and 17 b . By rotation it is possible to straighten it, for example until abutment on one of the ramps 22 a , 22 b : only then, by the play of the recess 20 b , the valve 17 b is connected to the 'outside.

Une dissymétrie de la canule et de son logement suffit à éviter toute erreur au montage ou en service; si au contraire le manchon 14 avait l'apparence de la symétrie, il serait bon de prolonger l'évidement 20b en 20c vers l'avant du plan de figure (trait mixte), sans que ce prolongement ait un rôle actif immédiat, pour obtenir une structure interne effectivement symétrique par rapport à un axe vertical, ce qui rendrait le montage indifférent.An asymmetry of the cannula and its housing is sufficient to avoid any error during assembly or service; if on the contrary the sleeve 14 had the appearance of symmetry, it would be good to extend the recess 20 b by 20 c towards the front of the plane of the figure (dashed line), without this extension having an immediate active role, to obtain an internal structure that is effectively symmetrical with respect to a vertical axis, which would make mounting indifferent.

On notera que le manchon pourrait aussi, non sans inconvénients il est vrai pour l'étanchéité, être coulissant. L'organe mobile, au besoin renvoyé par un ressort, pourrait même être un poussoir d'axe parallèle à ceux des flacons: agissant en dehors de lui l'opérateur provoquerait le transfert; ensuite, l'enfonçant, il mettrait le dispositif en position de pulvérisation.It will be noted that the sleeve could also, not without drawbacks, it is true for sealing, be sliding. The movable member, if necessary returned by a spring, could even be a pusher with an axis parallel to those of the bottles: acting outside of it the operator would cause the transfer; then, pushing it in, it would put the device in the spraying position.

Enfin une ceinture inviolable pourrait être placée sur le manchon, voire entre le pont et le boîtier à condition de modifier ce dernier pour permettre d'introduire les deux cartouches par le fond.Finally, a tamper-evident belt could be placed on the sleeve, or even between the bridge and the case, provided that the latter is modified to allow the two cartridges to be introduced from the bottom.
