Updated on by

Every year on the 29th of April, we celebrate a unique yet important event known as National Zipper Day. This day is devoted to appreciating the often overlooked but indispensable invention - the zipper, that is inextricably woven into our everyday lives. Present everywhere from our clothes and bags to camping equipment, this humble device never fails to express its relevance in numerous ways.

National Zipper Day is the perfect occasion to recognize and appreciate the ingenuity that resulted in such a practical invention. So, let’s find our best zipper-incorporated item and take part in celebrating this remarkable invention.

History of National Zipper Day

Every year on the 29th of April, we celebrate National Zipper Day. This is an occasion to recognize the humble yet essential invention that keeps various aspects of our everyday items, such as clothing, luggage, and camping equipment, firmly together.

This notable day is linked back to 1851 when Elias Howe, the man behind the sewing machine, obtained a patent for what he coined the “Automatic, Continuous Clothing Closure.” Despite patenting this device, Howe made no effort to advertise or sell the product, losing the opportunity to gain recognition for its invention.

Jump forth to 1893, and Whitcomb Judson was presenting his own version, the “Clasp Locker,” at the Chicago World’s Fair. While this early incarnation introduced a functional mechanism, it didn’t prove to be a hit on the market.

Fast forward to 1913, the modern zipper was introduced by Gideon Sundback, who was an employee of Judson’s company. The advanced fastener that Sundback developed had more fasteners per inch in comparison to the clasp locker, evolving into a more practical device.

Surprisingly, the fashion industry wasn’t quick to integrate the zipper into its designs. It found initial use in boots and bags, and only during the 1930s did clothing designs start to utilize the zipper’s potential.

Thus, National Zipper Day is an annual celebration of a bygone invention that has added a certain degree of convenience to our lives across a variety of industries and daily wear. The precise origin and reason why the day is celebrated on April 29th are still uncertain.
