Patent

CA 2162910

A bottomless pharmaceutical vial for filling, capping, and subsequent conversion into a syringe includes a shoulder (14) within its open bottom end (8) beneath a piston (10), and a retainer ring (20) snapped into engagement with the shoulder to retain the piston. The retainer ring has no part projecting beyond the external diameter of the vial, so that it may be installed prior to filling of the vial. A separate finger flange (32) may subsequently be snapped into place if required.

Fiole à fond ouvert pour produits pharmaceutiques pouvant être remplie, obturée et convertie ensuite en seringue, et comportant un épaulement (14) placé à l'extrémité côté fond ouvert (8), sous un piston (10) et une bague de retenue (20) encliquetée dans l'épaulement et maintenant le piston en place. L'anneau de retenue ne présente aucune partie saillante au-delà du diamètre extérieur de la fiole, ce qui permet de le mettre en place avant le remplissage de la fiole. Il est possible d'encliqueter par la suite une ailette séparée (32).
