Plug device for medication container e.g. glass vial, has manoeuvring element comprising annular edge engaged between external skirt of ring of cover and lip that forms locking unit and radially extends towards central axis of ring

摘要

#CMT# #/CMT# The device (500) has a manoeuvring element (504) mounted on a ring (503) of a cover (502) which covers a neck (12) of a container. The manoeuvring element has an annular edge (505D) adapted to be engaged between an external skirt of the ring and a lip (503G). The lip forms a locking unit and radially extends towards the central axis (X-503) of the ring, away from the skirt. The ring has an annular part at center of which an opening is defined to access an exposed face (501B) of a plug (501). #CMT# : #/CMT# An independent claim is also included for a method of mounting a plug device. #CMT#USE : #/CMT# Used for a medication container e.g. glass vial, utilized for conserving an active principle provided in the form of powder, liquid solution or freeze-dried product. #CMT#ADVANTAGE : #/CMT# The cover is made of plastic material so that the risk of generation of polluting glass particles by contact with the surface of the container is avoided. The manoeuvring unit can be mounted on the ring with any angular orientation so that the mounting of the cover is facilitated. The ring can be placed on the container in an easy manner. The annular edge permits to lock the ring in a simple and rapid manner without depending on the elasticity of the ring. The device can be automatically mounted and locked on the container. The plug device can be placed in an easy manner and permits to protect the elastomer plug until the end of filling operation and/or free drying cycle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a large scale view of a section of a plug device.
