Open the CIPO recordAbstract From the Canadian patent
A novel apparatus for compressing viscous material (100) through openings (48) in a stencil (46) is disclosed. The novel apparatus has a compression head (200) which provides a contained environment to direct and to aid the flow of pressurised viscous material (100) through the openings (48) in the stencil (46). Attached to the bottom surface (216) of the compression head are a pair of self-compliant blades (216) which are adapted to selectively engage the stencil (46) and to flexibly move across the stencil (46) and which are effective to spread the viscous material across the stencil (46).

Why it's free to use
- Filed July 6, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 6, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 6, 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.
