For the first several years of its existence, Coke was only available as a fountain drink, and its producer saw no reason for that to change. It was not until March 12, 1894 that Coke was first sold in bottles.

Originally developed as a non-addictive substitute for morphine, then marketed as a non-alcoholic "temperance drink," Coca-Cola was invented by John Pemberton, a druggist in Columbus, Georgia, in 1886. It was soon popular throughout the region, and the rights to the brand passed to Asa Griggs Candler.

On March 12, 1984, Mississippi shop owner Joseph A. Biedenharn began selling bottled Coca-Cola after he was impressed by its sales. He sold the drink to his customers in a common glass bottle called a Hutchinson, a common and reusable glass bottle that bore no resemblance to the modern Coke bottle.

At the time Biedenharn sent a case to Asa Griggs Candler, who owned the Company. Candler thanked him but took no action. One of his nephews had already urged that Coca‑Cola be bottled, but Candler focused on fountain sales.

Five years later, Candler finally sold the national bottling rights to Coke—excluding the right to bottle it in Vicksburg—to two brothers from Chattanooga. Still convinced that bottling would not be a major source of revenue, Candler sold the bottling rights for a dollar and reportedly never collected even that. The contract stipulated that a bottle of Coke would cost 5 cents and had no end date, a legal oversight that resulted in the price remaining the same until 1959.

In 1915, the bottlers put out a call for a new design, one so distinctive that one could recognize it if it were in pieces on the ground or by feeling it in the dark. The winning design, produced by the Root Glass Company of Terre Haute, Indiana, gave the world the iconic contoured bottle we know today.
