[0005] Further, preferably, a left-hand threaded slideway is provided on the outer side of the inner tube 2, and a limiting groove 202 is provided at the end position of the left-hand threaded slideway; the slideway is slidably connected to the supporting cylinder 301 on the inner wall of the outer tube.

[0006] Further, preferably, the sealing film 4 is arranged in the outer cylinder 3 above the mouth of the mineral water bottle by using a hot pressing film sealing device when pre-loading the tea powder.

[0007] The beneficial effects of the utility model are as follows: the instant tea bottle cap assembly is installed on the bottle body containing pure water or mineral water, and the inner cylinder 2 is in the initial position, and the cap body 1 is rotated counterclockwise to gradually separate from the outer cylinder 3, and at the same time, the inner cylinder 2 rotates downward to push open the sealing film 4, so that the tea powder falls into the mineral water bottle and mixes with the water to form cold brewed tea, which is convenient and hygienic to use, and can maximize the color, aroma and taste of the extracted tea powder. The bottle cap is unscrewed in a counterclockwise manner, which conforms to people's daily usage habits. BRIEF DESCRIPTION OF THE DRAWINGS
