Open the CIPO recordAbstract From the Canadian patent
A metal container which includes two drawn container halves joined by an injection molded plastic ring. The container halves can be identical and of low profile, with upstanding walls terminating in formed edges of substantially the same size and shape. The ring includes a pair of opposed channels sharing a common base, and the formed edges of the respective container halves fit into the opposed channels of the ring. The channels and formed edges are adapted to provide tailored fitting and retention characteristics so that one of the container half is gripped more securely by the ring, and the other container half is more readily removable.

Why it's free to use
- Filed March 10, 1997 and granted July 31, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 10, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 10, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
