STOPPER FOR SLIDING ZIPPERS AND METHODS FOR MANUFACTURING STOPPER FOR SLIDING ZIPPERS

Abstract

The invention relates to a locking device for sliding zippers and a method for producing a locking device for sliding zippers that can reduce mutual adhesion and the rate of failure during painting. The invention relates to a locking device of the type (10) for sliding zippers. The locking device (10) consists of a head (11) and two legs (12) extending from the head (11) in a split manner. Each of the legs (12) has a groove (20) in the middle of its inner surface (12b). The ratio of the depth (D) of the groove (20) to the thickness (E) of each leg (12) of the locking device (10) is greater than or equal to 3.8% and less than or equal to 18.9%. Furthermore, the ratio of the length (L2) of the groove (20) in the longitudinal direction of the stopper (10) to the length (LI) of the stopper (10) in the longitudinal direction can be greater than or equal to 13.5% and less than or equal to 23.5%.
