Description

La présente invention concerne un ensemble de conditionnement et de distribution d'un liquide, du type décrit dans le préambule de la revendication 1.The present invention relates to a set of packaging and dispensing a liquid, of the type described in the preamble of claim 1.

L'invention s'applique, par exemple, au conditionnement et à la distribution de médicaments destinés à une administration par voie orale.The invention applies, for example, to the packaging and dispensing of medicaments for oral administration.

On observera que l'invention concerne un ensemble dont la bague d'inviolabilité est formée d'une seule pièce avec le bouchon, par opposition au cas où ces deux éléments sont des pièces distinctes.It will be observed that the invention relates to an assembly whose tamperproof ring is formed integrally with the plug, as opposed to the case where these two elements are separate parts.

Dans un ensemble du type précité, la bague d'inviolabilité permet de s'assurer que l'ensemble de conditionnement et de distribution n'a pas été déjà utilisé.In an assembly of the aforementioned type, the tamperproof ring makes it possible to ensure that the packaging and distribution assembly has not already been used.

En effet, la région frangible est rompue dès la première utilisation, permettant ainsi de distinguer facilement les ensembles déjà utilisés des ensembles non-utilisés.Indeed, the frangible region is broken from the first use, thus making it easy to distinguish the already used sets of unused sets.

Un liquide, tel que l'un des médicaments mentionnés précédemment, ne doit pas être contaminé après son conditionnement et avant la première utilisation de l'ensemble de conditionnement et de distribution qui le contient.A liquid, such as one of the above-mentioned drugs, must not be contaminated after it has been packaged and before the first use of the packaging and dispensing unit containing it.

Ainsi, les bagues d'inviolabilité, dont la rupture est obtenue par simple retenue longitudinale de la bague par rapport au col lors du dévissage du bouchon, ne sont pas utilisables dans une telle application.Thus, tamper rings, whose break is obtained by simple longitudinal retention of the ring relative to the neck during unscrewing of the cap, are not used in such an application.

En effet, ces bagues d'inviolabilité, qui sont séparées des bouchons après un étirage purement longitudinal de la région frangible, permettent une rotation relative entre le bouchon et le col avant rupture beaucoup trop importante.Indeed, these tamper-evident rings, which are separated from the plugs after purely longitudinal stretching of the frangible region, allow a relative rotation between the plug and the neck before too much break.

Typiquement, le bouchon peut tourner d'un angle compris entre environ 90 et 120° autour de l'axe longitudinal avant que la région frangible ne se rompe.Typically, the plug can rotate at an angle of between about 90 and 120 ° about the longitudinal axis before the frangible region breaks.

Cette rotation relative est suffisamment importante pour permettre une contamination du liquide conditionné dans le récipient. C'est pour cela que de telles bagues d'inviolabilité ne sont pas utilisées dans le domaine d'application mentionné précédemment.This relative rotation is large enough to allow contamination of the conditioned liquid in the container. That is why such tamper-evident rings are not used in the field of application mentioned above.

On a préféré opter dans l'état de la technique pour des bagues d'inviolabilité dont la séparation par rapport au bouchon est provoquée, au cours du dévissage du bouchon, par un blocage en rotation de la bague d'inviolabilité par rapport au col du récipient.It has been preferred to use in the state of the art for tamper-proof rings whose separation with respect to the plug is caused, during the unscrewing of the plug, by a locking in rotation of the tamper-proof ring with respect to the neck of the container.

La région frangible, qui est généralement formée par des pontets, est alors soumise à un étirage non seulement longitudinal mais également latéral.The frangible region, which is generally formed by bridges, is then subjected to stretching not only longitudinally but also laterally.

Ces bagues d'inviolabilité permettent donc de garantir la stérilité du liquide contenu dans le récipient avant la première utilisation de l'ensemble de conditionnement et de distribution.These tamper-proof rings thus make it possible to guarantee the sterility of the liquid contained in the container before the first use of the packaging and dispensing assembly.

Toutefois, les risques liés à l'utilisation de tels ensembles de conditionnement sont encore trop importants.However, the risks associated with the use of such packaging packages are still too great.

Un but de l'invention est de résoudre ce problème en fournissant un ensemble du type précité qui permette de limiter les risques liés à son utilisation, notamment pour l'administration par voie orale d'un médicament.An object of the invention is to solve this problem by providing a set of the aforementioned type which limits the risks associated with its use, especially for the oral administration of a drug.

A cet effet, l'invention a pour objet un ensemble de conditionnement et de distribution selon la revendication 1.For this purpose, the subject of the invention is a packaging and dispensing assembly according to claim 1.

Selon des modes particuliers de réalisation, l'ensemble peut comprendre l'une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou selon toutes les combinaisons techniquement possibles :

  • l'organe de retenue est un disque,
  • les butées sont des crans,
  • l'ensemble comprend plusieurs saillies espacées angulairement autour de l'axe longitudinal et destinées à s'engager sous l'organe de retenue, et
  • la saillie ou chaque saillie comprend une surface de rampe inférieure adaptée pour permettre le franchissement des butées et de l'organe de retenue dans un seul et même mouvement du dispositif de fermeture par rapport au col.
According to particular embodiments, the assembly may comprise one or more of the following characteristics, taken in isolation or in any technically possible combination:
  • the retaining member is a disc,
  • the stops are notches,
  • the assembly comprises a plurality of projections spaced angularly about the longitudinal axis and intended to engage under the retaining member, and
  • the projection or each projection comprises a bottom ramp surface adapted to allow the crossing of the abutments and the retaining member in one and the same movement of the closure device relative to the neck.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés, sur lesquels:

  • la figure 1 est une vue schématique, latérale et partiellement en coupe, d'un ensemble de conditionnement et de distribution de liquide selon l'invention,
  • la figure 2 est une vue schématique, partielle, agrandie et en coupe, prise selon la ligne II-II de la figure 1, et illustrant les crans de blocage en rotation et le disque de retenue de la bague d'inviolabilité de l'ensemble de la figure 1,
  • la figure 3 est une vue schématique, en coupe longitudinale et agrandie du dispositif de fermeture de l'ensemble de la figure 1,
  • la figure 4 est une vue schématique en coupe prise suivant la ligne IV-IV de la figure 3,
  • la figure 5 est une vue schématique agrandie de la partie V de l'ensemble de la figure 1 avant utilisation, et
  • la figure 6 est une vue analogue à la figure 4 après séparation du bouchon de l'ensemble de la figure 1 en vue de son utilisation.
The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the appended drawings, in which:
  • the figure 1 is a schematic view, lateral and partly in section, of a liquid packaging and distribution assembly according to the invention,
  • the figure 2 is a schematic, partial, enlarged sectional view taken on line II-II of the figure 1 , and illustrating the rotational locking notches and the retaining disk of the tamper-evident ring of the whole of the figure 1 ,
  • the figure 3 is a schematic view, in longitudinal and enlarged section of the closure device of the whole of the figure 1 ,
  • the figure 4 is a schematic sectional view taken along line IV-IV of the figure 3 ,
  • the figure 5 is an enlarged schematic view of part V of the whole of the figure 1 before use, and
  • the figure 6 is a view similar to the figure 4 after separating the plug from the entire figure 1 for use.

La figure 1 illustre schématiquement un ensemble 1 de conditionnement et de distribution d'un médicament destiné à une administration par voie orale.The figure 1 schematically illustrates a set 1 for packaging and dispensing a medicament for oral administration.

Cet ensemble 1 comprend un récipient 3 et un dispositif 5 de fermeture du récipient 3.This set 1 comprises a container 3 and a device 5 for closing the container 3.

Le récipient 3 est dans l'exemple représenté un flacon en matière plastique. Ce flacon 3 contient le médicament sous forme liquide qui n'a pas été représenté sur les figures.The container 3 is in the example shown a plastic bottle. This vial 3 contains the drug in liquid form which has not been shown in the figures.

Le flacon 3 comprend un corps 7 prolongé par un col supérieur 9 de distribution du liquide. Le col 9 s'étend le long d'un axe longitudinal L. Cet axe L est orienté verticalement lorsque le flacon 3 repose sur le fond 11 du corps 7, comme illustré sur la figure 1.The bottle 3 comprises a body 7 extended by an upper neck 9 of liquid distribution. The neck 9 extends along a longitudinal axis L. This axis L is oriented vertically when the bottle 3 rests on the bottom 11 of the body 7, as shown in FIG. figure 1 .

De manière classique, les parois du corps 7 sont déformables élastiquement sous l'action d'un effort transversal pour provoquer une diminution du volume interne du corps 7 et ainsi permettre l'expulsion du liquide au travers du col 9.Conventionally, the walls of the body 7 are elastically deformable under the action of a transverse force to cause a decrease in the internal volume of the body 7 and thus allow the expulsion of the liquid through the neck 9.

Un embout compte-gouttes 13 est disposé à l'extrémité supérieure du col 9.A dropper tip 13 is disposed at the upper end of the neck 9.

Un passage 15 s'étend longitudinalement dans l'embout 13. De manière classique, le passage 15 présente un orifice aval 17 (en haut sur la figure 1) destiné à permettre la sortie du liquide hors du flacon 3 et l'entrée d'air à l'intérieur du flacon 3.A passage 15 extends longitudinally in the nozzle 13. In a conventional manner, the passage 15 has a downstream orifice 17 (at the top on the figure 1 ) for allowing the liquid to exit the bottle 3 and the air inlet inside the bottle 3.

Le col 9 présente plusieurs reliefs extérieurs parmi lesquels des filets supérieurs 19, des crans intermédiaires 21 et un disque inférieur 22.The neck 9 has several external reliefs including upper threads 19, intermediate notches 21 and a lower disc 22.

Comme illustré plus particulièrement par la figure 2, le col 9 comprend plusieurs crans 21, 10 dans l'exemple représenté, qui sont répartis angulairement autour de l'axe L.As illustrated more particularly by the figure 2 , the neck 9 comprises several notches 21, 10 in the example shown, which are angularly distributed about the axis L.

Les crans 21 possèdent des grandes faces de glissement 23 et des petites faces de blocage 25 qui se rejoignent pour former des extrémités extérieures 27 des crans 21.The notches 21 have large sliding faces 23 and small blocking faces 25 which meet to form outer ends 27 of the notches 21.

Les surfaces de glissement 23 s'étendent depuis l'intérieur vers les extrémités extérieures 27, dans le sens horaire de vissage matérialisé par la flèche V sur la figure 2.The sliding surfaces 23 extend from the inside towards the outer ends 27, in the clockwise screwing direction indicated by the arrow V on the figure 2 .

On notera que deux régions diamétralement opposées 29 du col 9 sont dépourvues de crans afin de permettre le démoulage du flacon 3 lors de sa réalisation.It will be noted that two diametrically opposite regions 29 of the neck 9 are devoid of notches in order to allow demolding of the bottle 3 during its production.

Exception faite de ces deux régions 29, les crans 21 sont répartis angulairement régulièrement autour de l'axe L.Except for these two regions 29, the notches 21 are angularly distributed regularly around the axis L.

Les crans 21 sont disposés juste devant le disque 22, c'est-à-dire sur celui-ci comme vu sur la figure 1.The notches 21 are arranged just in front of the disk 22, that is to say on it as seen on the figure 1 .

Plus précisément, les crans 21 s'étendent vers le haut depuis la surface supérieure 31 du disque 22. Ainsi, le disque 22 et les crans 21 sont venus de matière et forment un bloc.More precisely, the notches 21 extend upwards from the upper surface 31 of the disc 22. Thus, the disc 22 and the notches 21 are integral and form a block.

Le disque 22 est centré sur l'axe L et est orienté horizontalement. Son diamètre est tel que sa tranche extérieure 32 affleure les extrémités extérieures 27 des crans 21, comme on le voit sur la figure 2. En variante, le diamètre du disque 22 peut être plus important pour que sa tranche 32 soit espacée radialement vers l'extérieur par rapport aux extrémités 27 des crans.The disk 22 is centered on the axis L and is oriented horizontally. Its diameter is such that its outer edge 32 is flush with the outer ends 27 of the notches 21, as can be seen in FIG. figure 2 . Alternatively, the diameter of the disc 22 may be larger for its wafer 32 is spaced radially outwardly relative to the ends 27 of the notches.

Typiquement, la hauteur longitudinale h des crans 21 peut être d'environ 1,6 mm. L'épaisseur longitudinale e du disque 22 peut être d'environ 0,5 mm. Ces grandeurs h et e sont visibles sur la figure 5.Typically, the longitudinal height h of the notches 21 may be about 1.6 mm. The longitudinal thickness e of the disk 22 may be about 0.5 mm. These quantities h and e are visible on the figure 5 .

Comme illustré par les figures 3 et 4, le dispositif de fermeture 5 comprend un bouchon supérieur 33 et une bague d'inviolabilité inférieure 35. Le bouchon 33 et la bague 35 sont reliés, comme on le verra par la suite, par une région frangible, formée par des pontets frangibles 37. Seuls 3 pontets 37 sont visibles sur la figure 3 mais le dispositif 5 en comprend 5 dans l'exemple représenté. Ces pontets 37 sont répartis régulièrement angulairement autour de l'axe longitudinal L.As illustrated by figures 3 and 4 , the closure device 5 comprises an upper plug 33 and a lower tamperproof ring 35. The plug 33 and the ring 35 are connected, as will be seen later, by a frangible region, formed by frangible bridges 37. Only 3 bridges 37 are visible on the figure 3 but the device 5 comprises 5 in the example shown. These bridges 37 are distributed regularly angularly about the longitudinal axis L.

Les pontets 37 sont venus de matière avec le bouchon 33 et avec la bague d'inviolabilité 35 de sorte que le dispositif de fermeture 5 est formé par une seule pièce monobloc.The bridges 37 are integral with the plug 33 and with the tamperproof ring 35 so that the closing device 5 is formed by a single piece.

Le bouchon 33 comprend des reliefs intérieurs sous forme d'un téton supérieur 39 d'obturation du passage 15 de l'embout 13. Ce téton 39 fait saillie vers le bas depuis la paroi supérieure du bouchon 33.The plug 33 comprises internal reliefs in the form of an upper pin 39 for closing the passage 15 of the nozzle 13. This pin 39 projects downwards from the upper wall of the plug 33.

Le bouchon 33 présente en outre des filets intérieurs 41 disposés dans son tronçon central. Ces filets 41 sont complémentaires des filets 19 prévus sur le col 9. Au voisinage de chaque pontet 37, le bouchon 33 est prolongé vers le bas par des pattes 38 inclinées vers l'extérieur.The plug 33 further has internal threads 41 arranged in its central section. These nets 41 are complementary nets 19 provided on the neck 9. In the vicinity of each bridge 37, the plug 33 is extended downwards by tabs 38 inclined outwards.

La bague d'inviolabilité 35 comporte elle aussi des saillies intérieures parmi lesquelles des languettes 43 et des nervures 45.The tamper-proof ring 35 also has internal projections including tabs 43 and ribs 45.

Les languettes 43 sont par exemple régulièrement réparties angulairement autour de l'axe longitudinal L.The tabs 43 are for example regularly distributed angularly about the longitudinal axis L.

Dans l'exemple représenté, la bague d'inviolabilité 35 comprend cinq languettes 43.In the example shown, the tamper-proof ring 35 comprises five tabs 43.

Chaque languette 43 est inclinée et s'étend depuis son extrémité extérieure 47 venue de matière avec la bague 35 vers son extrémité intérieure 49, dans le sens opposé au sens V.Each tab 43 is inclined and extends from its outer end 47 integral with the ring 35 towards its inner end 49, in the direction opposite to the direction V.

Les extrémités inférieures des pontets 37 sont venues de matière avec les extrémités intérieures 49 des languettes 43.The lower ends of the bridges 37 are integral with the inner ends 49 of the tongues 43.

Les nervures 45 sont disposées longitudinalement à distance sous les languettes 43 et sont décalées angulairement de ces dernières. Ces nervures 45 ont une étendue angulaire de sorte qu'elles forment des arcs de cercle. Ces nervures 45, au nombre de 5 dans l'exemple représenté, sont par exemple régulièrement réparties angulairement autour de l'axe longitudinal L. Les nervures 45 ont une section convexe et présentent ainsi une surface de rampe inférieure 51 inclinée vers le bas et vers l'extérieur et une surface supérieure 53 inclinée dans le sens opposé.The ribs 45 are disposed longitudinally at a distance below the tabs 43 and are angularly offset from the latter. These ribs 45 have an angular extent so that they form arcs of a circle. These ribs 45, 5 in number in the example shown, are for example regularly distributed angularly about the longitudinal axis L. The ribs 45 have a convex section and thus have a lower ramp surface 51 inclined downwards and towards the outside and an upper surface 53 inclined in the opposite direction.

Initialement, le flacon 3 et le dispositif de fermeture 5 sont fournis séparés, les pontets 37 étant alors intacts.Initially, the bottle 3 and the closing device 5 are supplied separately, the bridges 37 then being intact.

Après remplissage du flacon 3 et fixation de l'embout 13 sur ce dernier, on vient assembler le dispositif de fermeture 5 sur le col 9.After filling the bottle 3 and fixing the tip 13 on the latter, the closure device 5 is assembled on the neck 9.

Cet assemblage est assuré par vissage du bouchon 33 sur le col 9, c'est-à-dire par rotation du bouchon 33 autour de l'axe L dans le sens V par ra p-port au col 9. Au cours de ce mouvement, les filets extérieurs 19 du col 9 et les filets intérieurs 41 du bouchon 33 coopèrent pour provoquer le déplacement vers le bas du dispositif de fermeture 5 par rapport au flacon 3.This assembly is ensured by screwing the plug 33 on the neck 9, that is to say by rotation of the plug 33 about the axis L in the direction V by ra p-port at the neck 9. During this movement , the outer threads 19 of the neck 9 and the inner threads 41 of the plug 33 cooperate to cause the downward movement of the closure device 5 with respect to the bottle 3.

Lorsque les surfaces de rampe 51 des nervures 45 rencontrent les crans 21, il faut exercer un couple de rotation plus important et une poussée vers le bas sur le bouchon 33. Les pattes 38 viennent alors prendre appui sur la bague d'inviolabilité 35 qui rencontre, du fait des crans 21, une résistance à sa descente longitudinale. Du fait de la poussée exercée, les crans 21 provoquent, grâce à l'inclinaison des surfaces de rampes 51, une légère expansion élastique de la bague 35 qui va permettre le passage des nervures 45 autour des crans 21 et du disque 22.When the ramp surfaces 51 of the ribs 45 meet the notches 21, it is necessary to exert a greater torque and a downward thrust on the plug 33. The tabs 38 then come to bear on the ring inviolability 35 which meets, because of the notches 21, resistance to its longitudinal descent. Due to the thrust exerted, the notches 21 cause, thanks to the inclination of the ramp surfaces 51, a slight elastic expansion of the ring 35 which will allow the ribs 45 to pass around the notches 21 and the disc 22.

La hauteur globale du bloc formé par les crans 21 et le disque 22 est suffisamment faible pour qu'un seul et même mouvement de descente permette aux nervures 45 de franchir ce bloc.The overall height of the block formed by the notches 21 and the disc 22 is small enough that a single downward movement allows the ribs 45 to cross this block.

Les nervures 45 sont alors passées sous le disque 22 et les languettes 43 sont en regard des crans 21.The ribs 45 are then passed under the disk 22 and the tabs 43 are opposite the notches 21.

L'ensemble 1 est alors dans sa configuration assemblée avant utilisation illustrée par les figures 1 et 5.The assembly 1 is then in its assembled configuration before use illustrated by the figures 1 and 5 .

Sur la figure 5 qui est une vue agrandie de la partie V de la figure 1, on peut constater qu'il existe alors un jeu J entre la surface supérieure 31 du disque 22 et les extrémités inférieures des languettes 43. Ainsi, les languettes 43 n'ont pas été endommagées lors de l'assemblage du dispositif de fermeture 5 et du flacon 3.On the figure 5 which is an enlarged view of the V part of the figure 1 it can be seen that there is then a clearance J between the upper surface 31 of the disc 22 and the lower ends of the tongues 43. Thus, the tongues 43 have not been damaged during the assembly of the closure device 5 and of the bottle 3.

Si l'on entraîne en rotation le bouchon 33 autour de l'axe L par rapport au col 9 dans le sens opposé au sens V, les extrémités intérieures 49 des languettes 43 viennent en appui contre des faces de blocage 25 des crans 21. Cette entrée en contact s'effectue typiquement après une rotation inférieure à 30°.If the plug 33 is rotated about the axis L with respect to the neck 9 in the direction opposite to the direction V, the inner ends 49 of the tongues 43 bear against the locking faces 25 of the notches 21. contacting is typically performed after a rotation less than 30 °.

Si la rotation relative s'interrompt alors, celle-ci n'a pas été suffisante pour que des agents contaminants aient pu pénétrer à l'intérieur du flacon 3 via le passage 15 de l'embout compte-gouttes 13. Si la rotation relative se poursuit, les languettes 43 s'arc-boutent contre les faces de retenue 25 des crans 21.If the relative rotation is then interrupted, it has not been sufficient for contaminating agents to have been able to penetrate inside the bottle 3 via the passage 15 of the dropper tip 13. If the relative rotation continues, the tabs 43 are braced against the retaining faces 25 of the notches 21.

Les crans 21 bloquent alors la bague 35 en rotation autour de l'axe L dans le sens opposé au sens V par rapport au col 9.The notches 21 then block the ring 35 in rotation about the axis L in the direction opposite to the direction V with respect to the neck 9.

Le dévissage du bouchon 33, c'est-à-dire la rotation dans le sens opposé au sens V, se poursuivant, les pontets 37 sont alors soumis à des efforts d'étirage longitudinaux et latéraux qui provoquent très rapidement leur rupture.The unscrewing of the plug 33, that is to say the rotation in the direction opposite to the direction V, is continued, the bridges 37 are then subjected to longitudinal and lateral stretching forces which very quickly cause their rupture.

Le bouchon 33 est alors séparé de la bague d'inviolabilité 35. Le dévissage du bouchon 33 peut alors se poursuivre librement jusqu'à son dégagement complet du col 9.The plug 33 is then separated from the tamperproof ring 35. The unscrewing of the plug 33 can then continue freely until it completely disengages the neck 9.

La figure 6 illustre l'ensemble 1 à l'issue de ce dégagement. Si l'on veut administrer le liquide contenu dans le flacon 3, on retourne l'ensemble 1 pour venir disposer l'embout 13 en regard de la bouche ouverte d'un patient, par exemple un jeune enfant.The figure 6 illustrates the set 1 at the end of this release. If it is desired to administer the liquid contained in the bottle 3, the assembly 1 is turned over in order to dispose the tip 13 facing the open mouth of a patient, for example a young child.

On appuie alors sur les parois latérales du corps 7 du flacon 3 jusqu'à administrer le nombre de gouttes souhaité. Au cours de cette distribution, les surfaces supérieures 53 (comme vu sur la figure 5) des nervures 45 viennent prendre appui contre la surface inférieure 57 (comme vu sur la figure 5) du disque 22.Then press the side walls of the body 7 of the bottle 3 until administering the desired number of drops. During this distribution, the upper surfaces 53 (as seen on the figure 5 ) ribs 45 come to bear against the lower surface 57 (as seen on the figure 5 ) of the disc 22.

Le disque 22 retient alors la bague 35 par rapport au col 9 contre l'effet de la gravité.The disc 22 then retains the ring 35 relative to the neck 9 against the effect of gravity.

Les risques de chute de la bague 35 du flacon 3 et d'ingestion de celle-ci par le patient sont donc éliminés.The risk of the ring 35 of the bottle 3 dropping and of ingestion of the latter by the patient are therefore eliminated.

En outre, l'ensemble 1 permet d'assurer une bonne stérilité du liquide avant distribution et de s'assurer qu'il n'a pas été déjà utilisé.In addition, the assembly 1 makes it possible to ensure good sterility of the liquid before dispensing and to ensure that it has not already been used.

Les coûts associés à l'ensemble 1 sont réduits car le dispositif de fermeture 5 est monobloc. Cet avantage est encore accru par la réalisation en un seul bloc du disque 22 et des crans 21 qui permet aux nervures 45 de franchir les crans 21 et le disque 22 au cours d'un seul et même mouvement du dispositif de fermeture 5.The costs associated with the assembly 1 are reduced because the closure device 5 is in one piece. This advantage is further increased by the one-piece construction of the disc 22 and the notches 21 which allows the ribs 45 to pass through the notches 21 and the disc 22 during a single movement of the closure device 5.

En variante, on observera que cette dernière caractéristique peut être absente.As a variant, it will be observed that this last characteristic can be absent.

Dans d'autres variantes également, le disque 22 de retenue longitudinale de la bague d'inviolabilité 35 après séparation du bouchon 33 peut être remplacé par un organe de retenue séparé des crans 21 et ayant une forme différente de celle d'un disque.In other variants also, the disc 22 of longitudinal retention of the tamperproof ring 35 after separation of the plug 33 may be replaced by a retaining member separated from the notches 21 and having a shape different from that of a disc.

En particulier, cet organe de retenue peut comprendre plusieurs tronçons répartis angulairement autour de l'axe L. De même, les nervures 45 peuvent être remplacées par un jonc continu ou discontinu, ou avoir d'autres formes que celles décrites précédemment.In particular, this retaining member may comprise several sections angularly distributed about the axis L. Similarly, the ribs 45 may be replaced by a continuous ring or discontinuous, or have other forms than those described above.

On notera également que le liquide contenu n'est pas nécessairement un médicament destiné à une application par voie orale. De manière générale, l'invention peut être appliquée à la conservation et à la distribution de tout type de liquide.Note also that the liquid contained is not necessarily a drug for oral application. In general, the invention can be applied to the preservation and distribution of any type of liquid.
