| 摘要 |
The present invention relates to a sealing device for a container having an opening and an outer projection, including: a septum for closing said opening, a cap having a retainer capable of switching from a first position, in which the retainer does not limit the axial movement of said cap with respect to said container, to a second position, in which the retainer limits the axial movement of the cap, and a sleeve receiving said cap and movable axially with respect to said cap between a distal position, in which said sleeve does not exert a radial inward force on said retainer, and a proximal position, in which said sleeve exerts a radial inward force on said retainer. The sleeve includes a guiding element capable of cooperating directly or indirectly with said outer projection, so as to limit rotation of said sleeve. |

1. A sealing device for a container having a proximal end and a distal end, said distal end being provided with a collar defining an opening aligned on an axis A and provided with an outer flange, said container being provided on its outer wall with at least one outer projection, the sealing device comprising:
a septum sealingly engageable with said opening when said sealing device is mounted on said container; a cap receiving said septum and capable of receiving at least part of said collar when said sealing device is mounted on said container, said cap comprising a retainer capable of switching from a first position, in which the retainer does not limit axial movement of said cap with respect to said collar when said sealing device is mounted on said container, to a second position, in which the retainer limits said axial movement under action of a radial inward force exerted thereon; and a sleeve receiving said cap and movable axially with respect to said cap between a distal position, in which said sleeve does not exert a radial inward force on said retainer, and a proximal position, in which said sleeve exerts radial inward force on said retainer, wherein said sleeve comprises a guiding element capable of cooperating directly or indirectly with said at least one outer projection of said container, so as to limit rotation of said sleeve with respect to said container when said sleeve is in the proximal position, regardless from the orientation with which the sealing device is mounted on said container, and wherein the guiding element comprises a plurality of radial teeth, each of said radial teeth having a top portion defined by a pair of angled surfaces that are angled in a radial or latitudinal direction. |
