On February 2, 1892, the bottling of liquids changed forever with the invention of the crown cap. William Painter, an inventor from Ireland who emigrated to the U.S. in the mid-19th century, designed the crown cap (or crown cork), a piece of metal with 24 teeth that clamped around the round mouth of a glass bottle of soda or, more importantly, beer. Rather than pop a cork from a pressurized bottle, you would now need a bottle opener to get at your drink.
