[0024] Specific embodiment 1: Please refer to Figure 1-Figure 6 A beverage cover for preventing a sealing film from falling comprises a cover base 1, an inner container 2 and a cover cap 3.
[0025] The cover seat 1 is installed at the bottle mouth, and a sealing film is arranged at the bottle mouth. The sealing film is located at the bottom of the cover seat 1 .
[0026] The outer thread and the inner thread of the cover seat 1 are arranged in opposite directions. The inner liner 2 is threadedly connected to the opening of the cover seat 1. The cap 3 is threadedly connected to the outer side of the cover seat 1 to block the opening of the cover seat 1. The cap 3 can selectively abut the inner liner 2 to drive the inner liner 2 to rotate. The feeding direction of the cap 3 is opposite to that of the inner liner 2.
[0027] A gap is formed between the external thread of the inner liner 2 and the internal thread of the cover seat 1, and the gap is a rotation channel for thread matching. At least one tight-fitting protrusion 23 is fixedly provided at the upper end of the outer peripheral surface of the inner liner 2. When the inner liner 2 rotates during operation, the tight-fitting protrusions 23 are all slidably connected in the rotation channel with interference fit. The tight-fitting protrusions 23 are located on the extended side of the tail of the external thread of the inner liner 2.
[0028] A plurality of steering contacts 31 are fixedly provided at the bottom of the cap 3. A matching steering block 21 is fixedly provided on the inner wall of the inner liner 2. During installation, the steering contacts 31 are embedded in the inner liner 2 and abut against the side of the steering block 21. In this embodiment, the number of the steering contacts 31 and the steering block 21 are both three; and they are all equally spaced and circumferentially distributed around the center of the cap seat 1.
[0029] At least one steering block 21 has an anti-drop rod 4 fixedly disposed downwardly at the bottom. The anti-drop rod 4 has a tip disposed toward the sealing membrane, and a support ring 41 is disposed between the tip and the connection between the anti-drop rod 4. The support ring 41 protrudes outwardly along the circumference of the anti-drop rod 4. In this embodiment, an anti-drop rod 4 is fixedly disposed downwardly at the bottom of each steering block 21. The number of steering blocks 21 and anti-drop rods 4 is equal.
[0030] The film-breaking sawtooth 22 is also included. The film-breaking sawtooth 22 is arranged on the lower end surface of the inner container 2. The film-breaking sawtooth 22 includes a plurality of oblique teeth, and the lower ends of the oblique teeth are flush.
