Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper and a zipper mould. Background Art

[0002] Existing zipper teeth are usually arranged in a staggered manner on both sides, for example, in the zipper teeth provided in CN02217364.1, the sprocket teeth 2 and the sprocket teeth 3 are arranged in a staggered manner, that is, each sprocket tooth 3 is located between two opposing sprocket teeth 2. Since the sprocket teeth 2 and the sprocket teeth 3 pass through the concave grooves 200 and 300, they have better tensile resistance, that is, they are more stable when subjected to reverse tensile forces, but this design is prone to problems when subjected to opposite pressures.
