[Abstract] the change range is within a certain range. The utility model discloses a rotary long opening easy-to-pull bottle cap, which comprises a bottle cap body and a pull ring. The included angle is set on the top plane of the cap α 2 °≤ α The utility model has the following advantages: the opening force of the easy to pull bottle cap is reduced, and the opening force is reduced by more than 74% compared with the conventional opening space, which can be adjusted through the lifting of the lower beam. The bottle cap can be opened easily and conveniently without any opening appliance, so as to promote the marketization of the product. In addition, since the utility model retains the geometry and basic size of the traditional crown shaped bottle cap, it is not necessary for the manufacturer to change the original filling line equipment for producing beer, soft drink and other beverages, which will not increase the production cost of the enterprise, but also be conducive to the technical development of the industry and the prosperity of the market
