Zipper

A zipper, zip, fly, or zip fastener, formerly known as a clasp locker, is a commonly used device for binding the edges of an opening of fabric or other flexible material, such as on a garment or a bag. It is used in clothing (e.g., jackets and jeans), luggage and other bags, sporting goods, camping gear (e.g. tents and sleeping bags), and other items. Zippers come in all different sizes, shapes, and colors. Whitcomb L. Judson, who was an American inventor from Chicago, is sometimes given credit as the inventor of the zipper, but his device was used for footwear not clothing. The method, still in use today, is based on interlocking teeth. Initially, it was titled the "hookless fastener" and was later redesigned to become more reliable.
