The first surface is arranged to be positioned so that it faces into a trough in a mold wall and this first surface is provided with a pair of elongated flexible sealing lips adjacent the edges of the area.

Why it's free to use
- Filed August 24, 1990 and granted November 9, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 24, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 24, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
