Open the CIPO recordAbstract From the Canadian patent
The present invention provides a child resistant container suitable for packaging of medicines and the like wherein a bottom portion designed to hold the product and a cover member have first and second cooperative locking devices with the first locking device permitting a certain limited movement while maintaining a locked position such that when the second locking device is moved to an unlocked position the first locking device remains locked until a second step or operation is performed thereon. Operation of the second locking device to unlock it tends to reinforce the locking action to the first locking device to prevent simultaneous unlocking of both locking devices.

Why it's free to use
- Filed September 24, 1993 and granted December 18, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 24, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 24, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
