Open the CIPO recordAbstract From the Canadian patent
The device for mixing and dispensing multi-component compositions is distinguished in that a cap (10) acting as a closure initially closes the outlet openings (5) of the components and can be moved into the open position by pressure of the components while they are being discharged so that the components can be mixed by the mixing helix (13) and emerge from the outlet tube (12).

Why it's free to use
- Filed November 19, 2003 and granted February 5, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 19, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 19, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
