Context

Country: Canada
State/Province: Unknown
Period: Presumably used in 1920s-1930s, and possibly later.
Canada: Made in Toronto, Ont. by Radium Health Products of Canada. Typical of containers designed, manufactured, sold and used in Canada for this purpose in 1920-1930s.
Function: To cover and protect from contamination, evaporation, etc. contents of jar believed to have been used contain and store water being treated with radium, for drinking.
Technical: Device popularized in 1920 -1930s as means of imparting "curative" properties of radon/radioactivity to drinking water for home/private consumption. Because radon cannot remain in water for any length of time before breaking down or escaping, jars like these were promoted as a means of 'making' radon-enriched water for drinking. The radon produced by the disk (.3) would dissolve overnight in the water filled jar.
Area Notes: Unknown
