Open the CIPO recordAbstract From the Canadian patent
A disposable child's drinking cup has a lid with a drinking spout defining multiple open holes sized to resist leakage in the absence of suction such as by the development of surface tension at the holes and to allow flow when suction is applied. The holes are formed during molding of the lid. An inner contour of a groove of the lid and an outer contour of the cup body rim are selected to provide a slight snap fit of the lid onto the cup body to provide a secure seal.

Why it's free to use
- Filed October 4, 2002 and granted August 30, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 4, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 4, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
