Open the CIPO recordAbstract From the Canadian patent
The invention is a package including a bundle of shirred casing sticks disposed and held together by a container which completely encloses the bundle. The container is formed insitu about the bundle from a heat shrink film which stiffens on heat shrinking to provide a self-supporting container conforming in shape generally to the bundle shape. During heat shrinking, portions of the film are insulated to prevent welding of these portions so they provide flaps which open to permit removal or replacement of sticks.

Why it's free to use
- Filed February 22, 1994 and granted September 23, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 22, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 22, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
