Which country first invented the zipper?

The situation is as follows:

1, zipper, also known as zipper, is one of the top ten inventions that facilitate people's lives in modern times;

2. 1893, Judson, an engineer in Chicago, USA, used small particle components as connectors and staggered at the edges of two cloth belts.

3. The purpose of engagement or separation is achieved through a sliding piece, which is the embryonic form of the current zipper. At that time, it was called "zipper" or "movable buckle";

The popular "movable button" was later modified by a clever American. He enlarged the top of the granular component to make it have a certain curvature, so that the component is not easy to explode automatically, which makes people laugh.

With the continuous development of science and technology and the unique design of skilled craftsmen, today's zippers have become diverse, beautiful and durable.
