Open the CIPO recordAbstract From the Canadian patent
An improved lottery ticket dispenser includes a burster wheel (26) having a planar contact surface (76). The improved burster wheel (26) provides for an increased range of operation (80) so that greater misalignment between the perforation or line of weakness (16) between adjacent tickets (12) in a fanfold stream (14) and the path of the burster wheel (26) can be accommodated while still providing a reliable and effective separation of the adjacent tickets (12) along the line of weakness (16).

Why it's free to use
- Filed April 7, 1997 and granted June 24, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 7, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 7, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
