The present invention relates to a container, and more particularly to a two-stage screw-turn structure having a bottle and a bottle cap and having a segmented positioning function when the cap is opened.

According to the current, the beverage bottles and pharmaceutical bottles on the market are mainly made of plastic bottles made of easy, light weight, low cost and high pressure resistance. Most of the currently available beverages and pharmaceuticals are sold in advance, so there are often problems with the shelf life and the use of chemical additives, such as clouding agents, emulsifiers and antioxidants. In the case of deterioration, taste, oil, etc., excessive chemical additives are used for a long time in the human body, and there are unclear health problems.

In order to improve the pre-modulation problem and avoid the use of chemical additives such as clouding agents and emulsifiers, it is necessary to design a mixture of liquids and liquids before drinking to maintain the freshness of the beverage.

At present, the mixed tanks before drinking, such as the Republic of China Patent No. M339497, No. M339496, No. M269809, No. M334100, No. M353914, etc., each of the aforementioned patents has multiple components or molds. The problems of high cost, high cost of mold injection, high cost of finished products, complicated assembly, etc., all have common shortcomings, and they are unable to carry out comprehensive automated quantitative production.
