Open the CIPO recordAbstract From the Canadian patent
A package is formed by holding a nonextensible strip taut and wrapping it around the upper and/or lower periphery of the bundle and joining the ends of the strip segments e.g. by adhesive bonding. A projecting margin of the strip is folded to overlie the bundle or underlie the bundle so that an L-configuration is imparted to the frame formed around the bundle after the strip is applied thereto.

Why it's free to use
- Filed August 29, 1991 and granted May 4, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 29, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 29, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
