Open the CIPO recordAbstract From the Canadian patent
The plastic substrate portion of the part is formed by a first injection of plastic into a mold, so as to adhere to an overlying sheet of coverstock material. A portion of the coverstock is not initially adhered to the substrate. A second injection of plastic forms the undecorated portion of the part and bonds to thesubstrate portion to form a unitary plastic panel. In the course of contacting the substrate portion, the plastic from the second injection folds and hides the nonadhered portion of the cover stock, thereby forming a neat clean split line.

Why it's free to use
- Filed April 19, 1996 and granted September 15, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 19, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
