【Sovereignty Items】 1. A kind of rotary long opening and easy-opening bottle cap, including a crown-shaped cap body and a pull ring with a circular top surface and skirt teeth around the top, and a top surface of the cover is provided with a lid. In the mouth, the pull ring is riveted and fixed on the top surface of the cover, characterized in that the opening is an easy-to-open engraved line, including a first straight line segment extending from a point on the cover top plane to the bottom edge of the crown-shaped skirt tooth, and The first straight section is connected at an acute angle to a second straight section extending from the top plane of the cover and an arc section connected with the second straight section, and the angle between the first straight section and the second straight section of the opening is included. The range of α is 2°≤α≤60°. The first straight section and the second straight section are arc-connected at the intersection point. The riveting point of the pull ring and the opening point of the opening are located at the center of the arc. The pull ring is rotatably riveted to the top surface of the cover, and the range of the rotatable angle β of the pull ring relative to the top surface of the cover is 0<β<360°. The length of the opening is greater than the radius of the skirt bottom edge D/2 , which is smaller than the sum of the radius d/2 of the circular plane of the cap top and the radius D/2 of the circumference of the bottom edge of the skirt.

【Abstracts】 The utility model discloses a rotary type long opening and opening easy-opening bottle cap, which comprises a bottle cap body and a pull ring, and a long opening is provided through an angle α of 2°≤α≤60° in the top surface of the cover. At the same time, in order to facilitate pulling up the setting of the pull ring, the pull ring can be rotated relative to the top surface of the cover to achieve the purpose of reducing the pulling force of the bottle cover. The utility model has the following advantages: the opening force of the easy pull bottle cover is reduced, Than the conventional opening force to reduce more than 74%. It can realize the purpose of easily and conveniently opening the bottle cap without any opening appliance and promote the marketization of the product. In addition, because the utility model retains the geometric shape and basic dimensions of the traditional crown-shaped bottle cap, it is not necessary for the manufacturer to change the original filling production line equipment for producing beer, soft drinks, etc., not only does not increase the production cost of the enterprise, but also It is conducive to the development of the industry's technology and conducive to the prosperity of the market.
