[SCG] glass washer bottles

Every bottle I have seen are the same and I believe the RD Canada and date
may have reflected the "Registered Design" patent date as this is common
practice on patented items. The labels did change over the years and the
Canadian labels on the bottle were different than the American labels.

Just ran across an old triangular glass washer bottle and while cleaning it
up noticed it said on the bottom "RD Canada 1961"
Also: " Patented Adell Chemical Company Detroit Mich."
Were these all date coded by year?
Were they all made in Canada?
Or were they made for Canadian production cars?
Just curious, I actually never noted the writing on the bottom before.
