Open the CIPO recordAbstract From the Canadian patent
An applicator having a substantially hollow body for accommodating an ampoule of solution is disclosed. The hollow body comprises an open proximal end for receiving the ampoule and an open distal end having a flange to accept an applicator pad for applying the solution. A back plug having a lever mechanism is inserted into the open proximal end of the applicator to activate the applicator and seal the applicator after activation. Advancement of the back plug lever mechanism into the hollow body pivots the body of the ampoule to break the neck, activating the applicator. The back plug seals the proximal end after activation of the applicator.

Why it's free to use
- Filed May 26, 2004 and granted July 23, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 26, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 26, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
