Claims

[Claims for Utility Model Registration] A top wall is connected to the upper end of a cylindrical wall having a wide locking groove on the inner circumferential surface, and a plurality of holes are provided on the lower surface of the top wall that are inclined in the direction of the screw rotation force. an outer cap having a projecting piece hanging thereon and having a low-height locking protrusion protruding from the lower circumferential end of the top wall; A locking protrusion that engages with the locking groove is protrudingly provided on the outer peripheral surface of the spiral wall provided with a thread that screws into the cylinder, and the elastic wall of the top plate wall connected to the upper end of the screw cylinder wall is provided. It consists of a locking piece protruding from the lower end of one side and a locking piece protruding from the opposite side, and an inner cap having a low-height locking piece protruding from the upper circumferential edge of the top plate wall, which resists the elasticity of the elastic piece. When the outer cap is moved downwardly relative to the center cap and the outer cap is engaged with both of the locking protrusions from the direction of unscrewing, the proximal ends of the elastic pieces abut against each other. The safety screw cap has an inclined surface on the side in the direction of screwing and rotation of the locking piece.
