Peel-off type anti-fake safety bottle cap

Abstract

The invention provides a peel-off type anti-fake safety bottle cap. The peel-off type anti-fake safety bottle cap comprises an outer cap body and an inner cap body. The inner cap body is embedded into the outer cap body, a top cap body is arranged at the upper portion of the outer cap body, two connecting points are arranged between the top cap body and the outer cap body, connecting points are arranged on the side face of the outer cap body, reverse hooks of the outer cap body are in interference fit with a bottle opening, a protruding end face of a flange of the outer cap body is in interference fit with the lower end face of the inner cap body, rotation-preventing teeth of the outer cap body are matched with rotation-preventing teeth of the bottle opening, a thread of the inner cap body is in thread fit with the bottle opening, and a sealing face of the inner cap body is in interference fit with the internal diameter of the bottle opening. According to the peel-off type anti-fake safety bottle cap, the rotation-preventing teeth on the side face are removed, assembling is stable, scrap pulling is not likely to occur, the cost for dies and raw materials is reduced, the time needed for assembling is shortened, the reliability of the peel-off type anti-fake safety bottle cap is improved, and the cost input of manpower and material resources is greatly reduced in the production process.

Description

technical field [0001] The invention belongs to the technical field of bottle caps, in particular to a tear-off anti-counterfeit safety bottle cap. Background technique [0002] In the tear-off bottle cap of the background art, the two components of the outer cap and the inner cap are positioned by the anti-rotation teeth on the side (such as Figure 4 ), at the same time, the screw and the anti-rotation gear must be positioned, which is troublesome to assemble, and the phenomenon of top teeth and scraping is easy to occur during assembly, the quality is not easy to guarantee during the production process, and the production efficiency and low cost are relatively high. Contents of the invention [0003] The invention provides a tear-off type anti-counterfeit safety bottle cap, which solves the disadvantages of the tear-off type bottle cap in the background art, such as troublesome assembly, easy top teeth and scraping. [0004] The technical solution of the present inventi...
