The contest is won in August 1915 by the Root Glass Company. Its designer Earl R. Dean had imitated the oval shape of a cocoa bean whose vertical streaks will appear embossed instead of grooved. The patent application is filed under the name of A. Samuelson on August 18 and accepted on November 16. This is the first patent granted by the Patent Office for a bottle shape.
The first prototype was not usable with a conveyor belt, requiring a modification of the diameters. Two prototypes of this second version identified by Coca-Cola as the 'classic contour bottle' have recently surfaced.
One of them, from the estate of Earl R. Dean, was accompanied by the autograph sketch made in 1915 by the inventor to show the front of the bottle with the Coca-Cola logo. The drawing of the back side, sent to Washington as an attachment to the patent application, is lost. Both lots were sold by Julien's on December 3, 2011 : for $ 240K including premium for the bottle and for $ 230K including premium for the drawing.
The other example had been kept by a Coca-Cola employee who had previously worked at Root Glass. This intermediate prototype is characterized by the Atlanta location featured on the heel. It may be earlier than the specimen that had been preserved by Dean. This bottle in mint condition is estimated $ 100K for sale by Morphy in Las Vegas on April 14, lot 2285 here linked on the LiveAuctioneers bidding platform.
