Detailed ways

Referring to Fig. 1 to Fig. 30, a anti-theft and leak-proof beverage bottle cap includes a cap body 1 and a straw 4, the cap body 1 is provided with an axial screw hole 2, and the cap body 1 is provided with the screw hole 2 The sealing sheet 3 that the lower end of the hole 2 is sealed. The outer wall of the lower end of the suction pipe 4 is provided with a screw thread matched with the thread of the screw hole 2. When the suction pipe 4 is rotated, the suction pipe 4 moves downward through thread fit, and the lower end surface of the suction pipe 4 pushes away the sealing sheet 3, After the sealing sheet is pushed back, the suction pipe is unimpeded to form a water outlet channel, and the liquid in the bottle body 34 can flow into the drinker's mouth through the straw.

Referring to Fig. 5, Fig. 10, Fig. 11 and Fig. 28, an elastic sealing film 5 is arranged inside the straw 4, and a water outlet slit 6 is arranged on the elastic sealing film 5. In the natural state, the water outlet slit 6 is closed and sealed. The water outlet inside the straw 4 is open, even if the bottle body is toppled over, the liquid will not leak out, and has a good leak-proof function. When the water outlet is opened when sucking, it can be drunk normally.

Referring to FIG. 4 , the lower end of the suction pipe 4 is provided with a convex point 27 for breaking the sealing sheet 3 , and the convex point 27 is preferably pointed and conical, which is convenient for scratching or pushing off the sealing sheet 3 .
