Abstract

A zipper head structure is disclosed, which includes a slider body, a pull-tab, and a locking hook. The slider body has a protrusion which is formed on the slider body. The pull-tab has a holding portion and an opening. The protrusion is located in the opening of the pull-tab. The locking hook has a base portion which is located over the hinge portion. The locking hook is disposed on the slider body. The base portion has a through hole. A stopper is downwardly formed by one side of the through hole. The hinge portion is disposed between the protrusion and the stopper. Thereby, by utilizing the stopper of the locking hook which is integrally formed, the movement of the hinge portion is effectively confined for preventing the pull-tab from separating with the slider body when pulling the zipper.
