Samuelson suggested the bottle be shaped like the coca bean or kola nut, the main ingredients of Coke for which it was named. A misunderstanding led Edwards to look up the cacao tree seed pod. The bottle was designed by Earl R. Dean, based on the 1910 Encyclopedia Britannica pictures. However, the patent on the bottle lists Alex Samuelson as the designer. It is speculated that his name is listed because he filed the paperwork.
The green color of the bottle was due to the Vigo County sand used in production. The site where the Root Glass Company was located has an Indiana Historical Marker with the symbol of the bottle. It is the only Indiana marker to have an image.
Unfortunately, when this bottle was taken into production it would not hold up. It was streamlined into the design we are familiar with today and was introduced to the public in January 1916.
