Description

La présente invention concerne une capsule métallique de bouchage d'un flacon contenant un liquide de culture.The present invention relates to a metallic capsule of closure of a bottle containing a culture liquid.

Dans le domaine des réactifs de diagnostic in vitro non injectable, la pratique courante consiste à prélever un échantillon de fluide, puis à cultiver cet échantillon dans un milieu de culture prêt à l'emploi pour en faire l'analyse par la suite.In the field of non-injectable in vitro diagnostic reagents, common practice is to take a fluid sample and then cultivate this sample in a ready-to-use culture medium for analysis thereafter.

Dans certaines applications, le milieu de culture est un liquide contenu dans un flacon. Le flacon est bouché par une capsule qui retient un joint. De manière connue, la capsule comprend une languette déchirable sur sa face supérieure, qui, lorsqu'elle est retirée, permet d'injecter un fluide à analyser dans le milieu de culture. Pour ce faire, le joint est percé par une aiguille par laquelle l'échantillon de fluide est introduit dans le flacon.In certain applications, the culture medium is a liquid contained in a bottle. The bottle is closed by a capsule which retains a seal. In known manner, the capsule comprises a tear-off tab on its upper face, which, when removed, allows to inject a fluid to analyze in the culture medium. To do this, the joint is pierced by a needle through which the fluid sample is introduced into the vial.

Un point important à signaler concernant le joint est que celui-ci présente généralement une jupe qui s'enfonce profondément dans le goulot du flacon. Cette disposition permet de résister à l'opération de stérilisation du flacon encapsulé au cours de laquelle le flacon est passé dans un autoclave.An important point to note about the seal is that it usually has a skirt that sinks deep into the neck of the bottle. This arrangement makes it possible to withstand the sterilization operation of the encapsulated bottle during which the bottle is passed through an autoclave.

L'échantillon après son introduction est alors laissé dans le milieu de culture de manière anaérobie (sans contamination venant de l'extérieur), puis après un certain temps, l'échantillon est prélevé pour être analysé.The sample after its introduction is then left in the middle anaerobic culture (without contamination from outside), then after a certain time, the sample is taken for analysis.

Pour ce faire, dans une première opération, la capsule est retirée du goulot du flacon puis, dans une deuxième opération, le joint est ôté du goulot pour pouvoir accéder au contenu du flacon.To do this, in a first operation, the capsule is removed from the neck of the bottle then, in a second operation, the seal is removed from the neck to be able to access the contents of the bottle.

Pour l'opérateur, cela s'avère peu pratique puisqu'il doit réaliser deux opérations successives.For the operator, this turns out to be impractical since he must carry out two successive operations.

Des capsules de ce type sont décrites par exemple dans les documents WO 01/83314, EP 794 129 et US 6 223 918.Capsules of this type are described for example in WO 01/83314, EP 794 129 and US 6,223,918.

Ainsi, ces documents montrent, sous des formes différentes, des capsules présentant une jupe ayant éventuellement des moyens d'inviolabilité et une tête ayant un opercule déchirable.Thus, these documents show, in different forms, capsules having a skirt possibly having tamper-evident means and a head having a tearable lid.

Ces capsules présentent toutes le même inconvénient qui est que, pour faire un prélèvement du liquide contenu dans le flacon, il faut opérer en deux temps, c'est-à-dire retrait de la capsule puis retrait du joint.These capsules all have the same disadvantage which is that, to take a sample of the liquid contained in the bottle, it is necessary to operate in two stages, that is to say removal of the capsule then removal of the seal.

Un but de l'invention est donc de proposer une capsule de flacon de milieu de culture qui soit d'une utilisation simplifiée.An object of the invention is therefore to propose a bottle cap culture medium which is of simplified use.

A cet effet, la capsule selon l'invention comprend

  • une tête présentant un opercule déchirable,
  • une jupe présentant une bague d'inviolabilité sur sa partie inférieure et une collerette sur laquelle vient en appui un joint d'étanchéité.
To this end, the capsule according to the invention comprises
  • a head with a tear-off cover,
  • a skirt having a tamper-evident ring on its lower part and a flange on which bears a seal.

Les caractéristiques de cette capsule assurent d'une part la garantie visuelle de la non contamination du milieu grâce à l'opercule déchirable et à la bague d'inviolabilité et, d'autre part, une grande facilité d'utilisation puisque, en un seul geste, l'opérateur retire la capsule du flacon et simultanément avec le joint d'étanchéité.The characteristics of this capsule ensure on the one hand the visual guarantee of non-contamination of the environment thanks to the seal tearable and tamper-evident ring and, on the other hand, great ease of use since, in a single gesture, the operator removes the capsule from the bottle and simultaneously with the seal.

Un autre avantage de cette capsule tient au fait que, grâce à sa collerette de retenue, elle peut être livrée avec un joint d'étanchéité et être mise en place sur un flacon sur une ligne d'embouteillage, sans qu'il soit nécessaire de gérer séparément la capsule et le joint.Another advantage of this capsule is that, thanks to its retaining flange, it can be delivered with a seal and be put in place on a bottle on a bottling line, without the need manage the capsule and the seal separately.

Avantageusement, la jupe présente un filetage complémentaire d'un filetage pratique sur un goulot du flacon, ce qui permet de refermer le flacon après un prélèvement.Advantageously, the skirt has an additional thread a practical thread on a neck of the bottle, which allows to close the bottle after collection.

De préférence, le joint d'étanchéité présente la forme d'un disque.Preferably, the seal has the shape of a disc.

Selon une possibilité, la bague d'inviolabilité est reliée à la jupe par des ponts ruptibles.According to one possibility, the tamper-evident ring is connected to the skirt by breakable bridges.

Dans une forme de réalisation, elle est réalisée en aluminium.In one embodiment, it is made of aluminum.

Pour sa bonne compréhension, l'invention est décrite en référence au dessin annexé représentant à titre d'exemple non limitatif une forme de réalisation d'une capsule selon celle-ci.

  • Figure 1 représente en coupe la capsule,
  • Figure 2 représente la capsule en vue de dessus.
    • For a good understanding, the invention is described with reference to the appended drawing representing by way of nonlimiting example an embodiment of a capsule according to this one.
  • Figure 1 shows in section the capsule,
  • Figure 2 shows the capsule in top view.

    • Comme on peut le voir sur figure 1, la capsule présente une tête 2 et une jupe 3.As can be seen in Figure 1, the capsule has a head 2 and a skirt 3.

    La partie inférieure de la jupe 3 est équipée d'une bague d'inviolabilité 5 reliée à celle-ci par des ponts ruptibles.The lower part of the skirt 3 is equipped with a ring inviolability 5 connected to it by breakable bridges.

    La jupe 3 présente par ailleurs un filetage complémentaire d'un filetage pratiqué sur un goulot 8 d'un flacon 9. La jupe 3 présente, en outre, sur sa partie supérieure une collerette 10 circonférentielle. Contre la collerette 10 vient en appui un joint d'étanchéité 12. Ce joint d'étanchéité 12 présente la forme d'un disque ayant une épaisseur pouvant varier entre 2 et 2,5 mm.The skirt 3 also has a complementary thread of a threaded on a neck 8 of a bottle 9. The skirt 3 has, in addition, on its upper part a circumferential collar 10. Against the collar 10 bears a seal 12. This seal 12 has the shape of a disc having a thickness which can vary between 2 and 2.5 mm.

    En se référant à la figure 2, on remarque, en outre, que la tête 2 de la capsule présente un opercule déchirable 14. L'opercule déchirable 14 est relié à la tête 2 de la capsule par des doubles ponts de matière 15. En outre, une languette 16 prolonge l'opercule 14. Referring to FIG. 2, it is further noted that the head 2 of the capsule has a tearable lid 14. The tearable lid 14 is connected to the head 2 of the capsule by double bridges of material 15. In addition, a tongue 16 extends the cover 14.

    La capsule ainsi décrite est donc sertie sur un goulot 8 d'un flacon 9 renfermant un liquide de culture. Après un passage dans un autoclave ce flacon 9 peut donc être utilisé pour la culture d'échantillon. Pour se faire, un opérateur saisit la languette 16 et retire l'opercule 14. Il peut ensuite introduire par la fenêtre ainsi ménagée dans la tête 2 de la capsule un échantillon à l'intérieur du flacon 9 en vue de la culture de celui-ci. L'introduction se fait grâce à une aiguille qui vient transpercer le joint d'étanchéité 12.The capsule thus described is therefore crimped onto a neck 8 of a bottle 9 containing a culture liquid. After passing through an autoclave this bottle 9 can therefore be used for sample culture. To do so, a operator grasps tab 16 and removes cover 14. He can then insert through the window thus provided in the head 2 of the capsule, a sample to inside the bottle 9 for the cultivation of the latter. The introduction is done thanks to a needle which pierces the seal 12.

    Lorsque la phase de culture s'est achevée, l'opérateur qui souhaite retirer l'échantillon pour en faire l'analyse dévisse la capsule, se faisant les ponts de rupture 6 se brisent laissant la bague d'étanchéité 5 sur le goulot du flacon. Cette bague témoigne alors du fait que la capsule a été ôtée et que ce qui est contenu à l'intérieur du flacon ne présente plus de garantie de pureté originelle.When the cultivation phase has ended, the operator who wishes to remove the sample for analysis and unscrew the capsule, making the fracture bridges 6 break leaving the sealing ring 5 on the neck of the bottle. This ring then testifies to the fact that the capsule has been removed and that this which is contained inside the bottle no longer guarantees purity original.

    Au cours du dévissage de la capsule le joint 12 reste en appui contre la collerette 10 contrairement aux dispositifs de l'art antérieur dans lesquels le joint restait enfiché dans le goulot, obligeant ainsi l'opérateur à retirer le joint au cours d'une opération séparée.During the unscrewing of the capsule the seal 12 remains in support against the flange 10 unlike the devices of the prior art in which the seal remained plugged into the neck, thus forcing the operator to remove the seal in a separate operation.

    La capsule selon l'invention présente donc un avantage substantiel par rapport aux capsules homologues de l'art antérieur.The capsule according to the invention therefore has a substantial advantage compared to the homologous capsules of the prior art.

    Comme il va de soi, l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple, mais elle en embrasse au contraire toutes les formes de réalisation. Ainsi, d'autres moyens peuvent être envisagés pour dégarnir le joint en vue d'accéder au milieu de culture.It goes without saying that the invention is not limited to the form of embodiment described above as an example, but it embraces otherwise all embodiments. So other ways can be envisaged to strip the joint in order to access the culture medium.
