Open the CIPO recordAbstract From the Canadian patent
The manner in which the product enters the container is determined by the various sub-processes previous to the filling process. Products can be liquid, low to high viscosity or paste. To dispense low to high viscosity and paste materials effectively, a vertical motion with rotation is applied to the container. Weight readings are taken continuously throughout all these movements without resulting in erroneous readings, while integrating functions of the other system components, such as the pressure and compression chamber, the inlet valve, etc.

Why it's free to use
- Filed February 27, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 27, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 27, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
