Open the CIPO recordAbstract From the Canadian patent
In methods for the manufacture of a multilayer tube shoulder a first material component is injected into a cavity (22). The said first material component is then removed from cavity (22) on a support (12) and in the partly plastic state. Following a zonal release the first material component is injected round with a further material component in a second cavity (23). This leads to a positive connection between the first and second material components.

Why it's free to use
- Filed February 16, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 16, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 16, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
