The inner surface of one or both of the slider arms is shaped so that as the slider is moved along the zipper in an opening direction one or both of the profiles is pivoted about the fulcrum thereby disengaging the profiles.

Why it's free to use
- Filed January 13, 2000 and granted March 19, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 13, 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.
