A new era for Coca-Cola began on November 16, 1915 when Coca-Cola patented a brand-new bottle shape.

For example, because Coca-Cola renewed its patent for the hobbleskirt shape on December 25, 1923, many bottles were embossed with this new patent date; as a result, these became known as “Christmas Coke” bottles, a romantic name that has spawned fictional tales of origin to explain the date.

Decades later, in the late 1950s, Coca-Cola decided to stop embossing the cities of origin on its bottles.

These four-digit numbers, which are separated into pairs by a dash, identify the bottle mold (the first two numbers) and the year of its manufacture (“30,” for example, would indicate 1930).

When it opened, it popped—which is how the term “soda pop” entered the American vernacular.

Unlike later, more familiar Coca-Cola bottles, Hutchinson bottles had straight sides without curves.

Each was embossed with “Coca-Cola”—either in block text or in script—and the name of the city where it was bottled.

Coca-Cola adopted crown tops relatively early, around 1902, impressed by its ability to keep the product fresh and unspoiled for longer periods of time than Hutchinson bottles.
