Publication number: 20240041168Abstract: A zipper strap structure according to an embodiment includes a first strap, a second strap disposed side by side with the first strap, an internal coupling unit, and an external coupling unit. According to the invention, the internal and external coupling of the zipper strap structure is performed with very high accuracy and precision. In addition, when the zipper strap structure is operated, a user can intuitively recognize whether the zipper strap structure is opened or closed by senses of touch and hearing. Since a user can effectively seal contents by the internal and external coupling of the zipper strap structure and can clearly recognize an operation state of the zipper by senses of touch and hearing, the user does not have to perform repeated checking of whether or not a zipper is completely closed, unlike the related art.Type: ApplicationFiled: October 26, 2021Publication date: February 8, 2024Inventors: Sang Kil JUNG, Won Sang CHO, Moon Seok SHIM
