On February 6, 1894 William Painter (1838-1906) received a patent for a "Capped Bottle Opener" (US. Patent number 514,200). Two years earlier Painter had received three patents for a "Bottle Sealing Device."
Ezra Warner was the inventor of the first can opener. He invented the can opener in the year 1858. Ezra was from Waterbury, Connecticut.
The bottle opener is a lever.
The fulcrum is the pivot point where the bottle opener rotates, typically located near the base of the bottle opener. The effort is applied by the user at the handle end of the bottle opener to lift the bottle cap. The load is the resistance provided by the bottle cap, which is located at the other end of the bottle opener.

The bottle opener is a lever.
A bottle opener is a common household or kitchen tool that is a simple machine (a lever).
The input force of a bottle opener is applied by the person using it to remove the bottle cap. This force is typically exerted by the hand or arm. The output force is the force exerted by the bottle opener on the bottle cap to lever it off the bottle.
The load in a bottle opener is the resistance provided by the bottle cap when you try to open it. It is the force required to overcome the seal and remove the cap from the bottle.
The purpose of the other side of a bottle opener is to provide a leverage point for lifting the cap off a bottle.
The first form of bottle cap, the crown cork (AKA crown cap AKA crown) was invented by William Painter in 1891 in Baltimore. This is the crown-shaped cap that you need a bottle opener for.
