The famous Coca-Cola bottle, called the "contour bottle" within the company, but known to some as the "hobble skirt" bottle, was created in 1915 by bottle designer Earl R. Dean. In 1915, the Coca-Cola Company launched a competition among its bottle suppliers to create a new bottle for the beverage that would distinguish it from other beverage bottles, "a bottle which a person could recognize even if they felt it in the dark, and so shaped that, even if broken, a person could tell at a glance what it was."
Chapman J. Root, president of the Root Glass Company, turned the project over to members of his supervisory staff, including company auditor T. Clyde Edwards, plant superintendent Alexander Samuelsson, and Earl R. Dean, bottle designer and supervisor of the bottle molding room. Root and his subordinates decided to base the bottle's design on one of the soda's two ingredients, the coca leaf or the kola nut, but were unaware of what either ingredient looked like. Dean and Edwards went to the Emeline Fairbanks Memorial Library and were unable to find any information about coca or kola. Instead, Dean was inspired by a picture of the gourd-shaped cocoa pod in the Encyclopedia Britannica. Dean made a rough sketch of the pod and returned back to the plant to show Mr. Root. He explained to Root how he could transform the shape of the pod into a bottle. Chapman Root gave Dean his approval. The prototype never made it to production since its middle diameter was larger than its base, making it unstable on conveyor belts.
Faced with the upcoming scheduled maintenance of the mold-making machinery, over the next 24 hours Dean sketched out a concept drawing which was approved by Root the next morning. Dean then proceeded to create a bottle mold and produced a small number of bottles before the glass-molding machinery was turned off.
Chapman Root approved the prototype bottle and a design patent was issued on the bottle in November, 1915. The prototype never made it to production since its middle diameter was larger than its base, making it unstable on conveyor belts. Dean resolved this issue by decreasing the bottle's middle diameter. During the 1916 bottler's convention, Dean's contour bottle was chosen over other entries and was on the market the same year. By 1920, the contour bottle became the standard for the Coca-Cola Company. Today, the contour Coca-Cola bottle is one of the most recognized packages on the planet..."even in the dark!". Dean reduced the middle diameter, creating the famed Contour Coca-Cola bottle.
As a reward for his efforts, Dean was offered a choice between a $500 bonus or a lifetime job at the Root Glass Company. He chose the lifetime job and kept it until the Owens-Illinois Glass Company bought out the Root Glass Company in the mid-1930s. Dean went on to work in other Midwestern glass factories.
