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.

Description

technical field [0001] The invention relates to an easy-pull bottle cap, in particular to a lever-type easy-pull bottle cap with an opening aid. Background technique [0002] The lever-type easy-open bottle caps on the market are composed of crown-shaped bottle caps and pull rings. The crown-shaped bottle caps are made of metal sheets. The pull rings include rings and lever pieces. The lever piece is riveted. There are invisible cuts (also called pre-stressed line cuts) on the crown bottle cap. The invisible cuts include an arc segment and two straight segments. The two ends of the straight line segment of the invisible cut extend to the edge of the crown bottle cap. , the arc segment of the invisible cut bypasses the riveting point between the crown bottle cap and the lever piece. When in use, pull up the pull ring to pull the part surrounded by the invisible cut away from the bottle cap to open the bottle cap. [0003] Although the above-mentioned existing lever-type ea...
