Abstract

The utility model discloses a single-gasket beverage bottle cap. An annular inner plug is arranged on a bottle cap top, and the part, making contact with the inner wall of a bottle neck, of the head portion of the annular inner plug is of an olive shape. A triangular annular outside seal is arranged outside the inner plug. An annular top seal is arranged between the olive-shaped annular inner plug and the triangular annular outside seal. A single-screw fastening structure is arranged inside a bottle cap side wall. Vertical anti-slip teeth are arranged outside the bottle cap side wall. A bottom cap skirt part is provided with a hook-type opening mark device which is connected with a cap body through bridge points. When the single-gasket beverage bottle cap is unscrewed, the olive-shaped annular inner plug makes contact with the inner wall of the bottle neck all the time and gets separated from the bottle neck only after the anti-theft annular bridge points are broken, so that it is guaranteed that a beverage is still in a sealed mode when the bottle cap is unscrewed; the design of the anti-theft annular bridge points guarantees that the anti-theft annular bridge points can be broken quickly and will not be elongated continuously due to the extensibility of plastic when the bottle cap is unscrewed. By the adoption of the single-gasket cap type, gasket materials affecting the taste of the beverage easily are omitted, the technological process for manufacturing the gasket materials is omitted, the overall weight of the bottle cap is reduced by 25%, and production cost is reduced.
