Open the CIPO recordAbstract From the Canadian patent
A litter bin includes a lid hingeably connected to a container. Opposite the hinge a latch selectively secures the lid to the container. The latch includes a pivotably mounted latch member. The latch member includes a catch portion that moves between a locked position and an unlocked position upon pivoting of the latch member. A weight is pivotably connected to the latch member at a point offset from the pivot axis of the latch member thereby further retaining the catch portion of the latch member in the locked position. The litter bin must be tilted past a nonzero tilt threshold before the latch member pivots the catch portion from the locked position to the unlocked position.

Why it's free to use
- Filed February 6, 2006 and granted July 2, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 6, 2026.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
