Most glass beverage bottles nowadays are molded with screw threads so you can twist the metal cap off with your fingers. But some — particularly beer bottles — still come with metal caps crimped onto the top. Those caps have a name: they’re “crown corks.” They were invented in 1892 in Baltimore, and not only represented a new way to seal bottles, but were also the first widely successful product that you just threw away. the crown cork would generally get bent when taking it off, and couldn’t be reused. Even if you take one off very carefully, it’s nearly impossible to put it back on the bottle.
Crown corks were an immediate hit and led to the rise of the Crown Cork and Seal Company — which still exists. And speaking of disposable products, another one is the disposable razor blade, which was developed by King Gillette (that was his name, not his title). He got the idea for razor blades from the crown cork when he was a salesman for the Crown Cork and Seal Company.
King Gillette had some unusual ideas for a rich industrialist — he thought all businesses should be consolidated into just one, which would be owned by the general public. He actually started that company, called the World Corporation. He tried to hire Theodore Roosevelt to be the CEO, and offered him a salary of a million dollars (back when that was real money, too). That idea never went anywhere, but he had another idea that had an interesting offshoot — he thought everyone in the US should settle in one single huge city. It would be powered by electricity produced by Niagara Falls, and would be called Metropolis.
Gillette wrote several books trying to popularize his ideas, and possibly because his portrait appeared on every package of “safety razor blades”, which were nationally popular, he sold quite a few books. Some of the ideas may have been floating around in the national imagination in the 1930s, when Superman comics appeared. Superman was based in Metropolis, which was located in New York state, within reach of electrical power from Niagara Falls.
Superman, as everyone knows, has superhuman strength and so would be easily able to replace a used crown cork on a bottle, crimping it shut with his super Kryptonian fingers. “Crimp” comes from the Old English word “crump”, which meant to fold or bend. By the 1700s it mostly was used to refer to hair (“Would you like your hair crimped, sir?” — 1786), but by the 1800s it also referred to attaching metal by folding it in a particular way: “The cylinders were crimped on to the bases of dummy Pettman’s percussion fuzes.” (1875). So the word was ready and waiting when crown corks came along.
Not having super Kryptonian fingers, most people needed a tool to remove the crown cork from a bottle — the tool is prosaically called a “bottle opener,” but by the middle of the 20th century it was widely recognized in the US as a “church key.” Nobody knows where that name originated. The tool was often stamped or enameled with ornate advertising, and given away. It was an early form of “freebie advertising” or “freebie marketing,” where you give away one thing (a bottle opener) to stimulate sales of your other things (bottles of beer). One of the first and most successful practitioners of this? King Gillette, who gave away the razors in order to sell the blades.
