CAP OF DRINK CONTAINER

摘要

The present invention is to make force for rotating a cover body and pushing a sliding locking member with the smaller number of components. Force is applied to the cover body (5) in a direction where the cover body (5) is opened by the elasticity of a ring-shaped elastic member (35) installed around a hinge shaft (15) in a closed state. Force is applied to the elastic member (35) in a direction where the sliding locking member (26) is locked inside the closed cover body (5). The locked state of the cover body (5) and the sliding holding member (26) is released to open the cover body (5) by the tension of the sliding holding member (26). The ring-shaped elastic member can lock the cover body (5) and a cap body (4) and can rotate the cover body (5). Also, the cover body is fixed by pulling the sliding locking member (26) using the tensile force of the ring-shaped elastic member (35).
