[0002] Bottle caps are used to seal bottles, and there are different shapes and different operation methods of bottle caps according to different functions, generally being circular and annular. Bottle caps are an important part of food and beverage packaging and are the first place for consumers to contact the product. Bottle caps have the performance of keeping the contents of the product sealed. With the progress of the times, bottles and bottle caps have more diversified designs, and there are different shapes and different operation methods of bottle caps according to different functions.

[0003] However, the existing soy sauce caps are all integrally injection molded by a flip cover and a lower cover, so the flip cover and the lower cover can only be the same color, resulting in poor appearance and increasingly not meeting the current demand for appearance. Therefore, many manufacturers have introduced double-color caps, but due to the difficulty of buckling the flip cover, the double-color caps all adopt a cover closing cover.

[0004] However, the bottle caps of the product currently have a common problem, that is, after opening, due to the lack of an oil bottle cap structure with a leak-proof and backflow function at the position of the bottle cap, a small amount of oil will be left at the bottle opening after pouring oil products such as tea oil and olive oil with high viscosity, and it can flow down along the outer wall of the bottle opening and stick to the surface of the oil bottle, easily sticking to dust, and the oil will accumulate into oil stains on the bottle body after a long time, which is very unhygienic and seriously affects the appearance of the oil bottle, and also causes great waste of oil products. Therefore, it does not meet the current demand, and for this purpose, a double-color cap is proposed. SUMMARY
