Zipper
The zipper, or zipper or rack fastener, is a mechanical device for the quick opening and closing of a garment or bag, or the quick connection and separation of fabric parts. The first rapid zippers were developed in the United States by engineers Elias Howe, Max Wolff and finally Whitcomb Judson in 1891. These first zippers with eyelets and hooks had the unfortunate tendency to open themselves, same. It was the American engineer Gideon Sundbäck who, in 1913, obtained the patent for the development of the modern zipper by replacing the system of eyelets and hooks with a device of teeth meshed with a cursor. In France and French-speaking Switzerland, the term "Éclair" is often used, which is a registered trademark of Éclair Prestil SN. As such, this term must be written with an initial capital letter. The English term "zip" is sometimes used.
