In 1932, an American named George Blaisdell watched a friend awkwardly trying to light a cigarette with a cheap Austrian-made lighter. To cover up the embarrassing nature of the lighter, his friend shrugged and said, "It works!" Afterward, Blaisdell went on to invent a simple-designed lighter that was unaffected by air pressure or low temperatures. He named it ZIPPO, inspired by another great invention of the time — the zipper (ZIPPER), and named it with the principle of "it works." Four years later, ZIPPO successfully obtained a patent from the U.S. government. Following its original structure, it was redesigned into a sleek rectangular case, with a hinge connecting the lid to the body. It also overcame design challenges by adding a perforated windproof wall around the flame core specifically designed for wind resistance. In the early 1940s, ZIPPO lighters became military supplies for the U.S. Army. With the outbreak of World War II, American soldiers quickly took a liking to them, praising their instant ignition and excellent windproof performance. In fact, in the 65 years since then, the appearance of ZIPPO has not changed much, but this patent has been developed almost perfectly. Every time you open the cap in the wind and ignite the flame core, you will experience the unique windproof design of ZIPPO.
