Open the CIPO recordAbstract From the Canadian patent
A process and apparatus are provided for assembling two, mating, threaded containers. The threaded end of the first container is disposed in the threaded port of the second container. The second container is clamped to prevent rotation of the second container. A cam is rotated to engage a torque-applying assembly to produce relative movement between the clamp assembly and the torque-applying assembly. This effects sequential engagement and disengagement of the torqueapplying assembly and the first container. The torqueapplying assembly is rotated relative to the clamp assembly while engaged with the first container to effect threaded engagement of the containers.

Why it's free to use
- Filed January 27, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 27, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 27, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
