In the 1880s, corks used for sealing bottles of various beverages did not seal them tightly enough and often broke apart.

to solve this problem, American inventor William Painter from Baltimore, Maryland, invented a crown-shaped cork for sealing bottles. This cork sealed the bottle completely airtight. It had a corrugated flange edge and a thin insert disc made of cork at the bottom of the bottle. The cork was simple and inexpensive to produce. In his patent No. 468258, granted on February 2, 1892, William Painter named this invention the Crown Cork. He also proposed a new design for bottles, as the bottle neck needed to have a gripping area to secure the cork in place. The Crown Cork is still widely used today, although the number of ridges on its corrugated flange edge has been reduced from 24 to 21.
