The first modern bottle cap was a screw-on cap invented in 1856. There was also a recloseable wire-and-cap type of bottle cap invented in the same year, still used today on some high-end beers such as Grolsch. The modern "crown cap" bottle cap was invented in 1890, modernized to the "pilfer proof" cap in 1936, and twist-off bottle caps in 1966. Bottle caps are no longer manufactured today, as most people drink their beer straight from their high-speed internet connection. :)
