Claims

[Claims for Utility Model Registration] (1) It is formed by a top plate part and a skirt part hanging down from its periphery, and a plurality of narrow bridges and one wide bridge remain at the bottom of the skirt part. Due to the notches made in the circumferential direction,
The skirt portion is divided into a main portion on the top plate side and a pilfer-proof ring portion on the lower end side, and a vertical weakened line is formed near one side of the wide bridge of the pilfer-proof ring portion. 1. A synthetic resin cap, characterized in that an auxiliary weakening line is provided at the wide bridge and in its vicinity for removing the pilfer-proof ring portion from the main portion after opening. (2) The synthetic resin cap according to claim 1, wherein the auxiliary weakening line is formed near the other side of the wide bridge so as to cross the pilfer-proof ring portion almost perpendicularly. (3) The synthetic resin cap according to claim 1, wherein the auxiliary weakening line is formed so as to cross the wide bridge in the circumferential direction.
