Who invented the beer stopper

In the 19th century, corks used to seal various drinks did not close the bottle tightly enough, which often led to spoilage of the drink.

In 1892, inventor William Painter invented a crown-like metal cork with teeth. In Patent No. 468258, the plug was named Crown Cork. The metal cap sealed the bottle hermetically and was inexpensive. The closure consisted of a metal cap with a wave-like rim, in which a cork circle was reinforced to eliminate any possibility of metal contact with the contents of the bottle. A metal cap with a cork inserted in it was placed on the opening of the bottle and squeezed the neck by means of pressure (the principle of a seaming machine).

Painter also proposed a project for a new type of bottle, since the bottleneck had to have a clamping area for fixing the cork.

Crown plugs are still widely used today, only the number of teeth on the corrugated flanged edge of the plug has been reduced from 24 to 21.
