Abstract
The invention relates to a lever-type ring-pull bottle cap with an opening-assisting line. The lever-type ring-pull bottle cap comprises a cap body and a pull ring. The pull ring comprises a pull ring loop and a lever piece which are integrally formed. The free end of the lever piece is riveted to the top face of the cap body. A first arc shear mark is arranged on the inner side of the top face of the cap body. The first arc shear mark is wound around the rivet point of the cap body and the lever piece. The two ends of the first arc shear mark extend towards one side of the cap body to form two linear shear marks. An opening-assisting line shear mark is arranged on the inner side of the top face of the cap body. One end of the opening-assisting line shear mark is connected with the first arc shear mark, and the other end of the opening-assisting line shear mark extends towards the reverse direction of the linear shear marks. The lever-type ring-pull bottle cap is simple in structure and reasonable in design, and the bottle cap is conveniently and rapidly opened with little labor due to the design of the opening-assisting shear marks.
