This month marks the 94th anniversary of the iconic Coca-Cola coutour bottle. Now, a treasured hallmark, this single shape of packaging has achieved iconic status since its creation in 1915. The Coca-Cola logo itself is the single most recognizable brand in the world. The first bottle was designed in 1915 by the Root Glass Company. The bottle designer, Earl R. Dean and his team decided to base the bottle design on the soda's two ingredients, the coca leaf or the kola nut. Dean couldn't find any photographs of either, but became inspired by the cocoa pod, and transformed the shape of the pod into a bottle: The 1915 Coke Bottle: A prototype of the first contour bottle developed by Root Glass Company in 1915. The prototype never made it to production since its middle diameter was larger than its base, making it unstable on conveyor belts. See the evolution of the contour bottle from 1916 to today, after the jump.
