The receptacle portion is provided for storing and displaying items related to the contents of the pail, e.g. small tools or instructions. The lid assembly may also have a pouring spout, either within or outside of the receptacle portion, so that the contents of the pail may be emptied without removing the entire lid assembly.

Why it's free to use
- Filed February 2, 1994 and granted June 6, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 2, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 2, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
