Title: METHOD FOR USING SINGLE-LAYERED CLOSING ZIPPER
Abstract:
A method for using a single-layered closing zipper. The single-layered closing zipper comprises a zipper base (1), a chain (2), and a steel tape measure (3). The chain (2) comprises a left chain (6), a right chain (7), a zipper head closing element (8), and a zipper tail closing element (9). The steel tape measure (3) comprises a housing (10) and a steel tape strip (11). The steel tape strip (11) is arranged above the zipper base (1). The left chain (6) is provided with left teeth (13) and a left tape (14). The left teeth (13) are provided with left insertion-proof plates (15) and left hooks (16). The right chain (7) is provided with right teeth (17) and a right tape (18). The right teeth (17) are provided with right insertion-proof plates (19) and right hooks (20). The left insertion-proof plates (15) are arranged at corresponding positions between the left teeth (13). The right insertion-proof plates (19) are arranged at corresponding positions between the right teeth (17). When in use, the single-layered closing zipper is arranged on a piece of luggage or a luggage bag, the left insertion-proof plates (15) block the corresponding gaps between one of the left teeth (13) and another of the left teeth (13), the right insertion-proof plates (19) block the corresponding gaps between one of the right teeth (17) and another of the right teeth (17), and the steel tape strip (11) of the steel tape measure (3) blocks the entrance of the chain (2), thus, when a criminal is inserting a sharp tool into the zipper, increasing the difficulty for the criminal to open the zipper by inserting the sharp tool.
