Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example one
As shown in figures 1, 2, 3, 4, 8. An anti-pulling-off bottle cap comprises an outer upper cap 1, an inner upper cap 2, a lower cap 3 and a bottle mouth 4.
The mouth 4 is fixedly connected to the lower cover (welding or fastening, for simplicity, the embodiment only takes welding as an example, and the fastening mode is shown in the following embodiments).
The lower cover 3 is provided with a lower cover reverse buckle 33 (matched with a locking hoop 61 of the bottle neck 6 to prevent the lower cover 3 from being pulled up) and a lower cover anti-rotation rib 32 (matched with an anti-rotation rib 62 of the bottle neck 6 to prevent the lower cover 3 from rotating).
The outer side of the bottle mouth 4 is provided with a bottle mouth thread 41.
The inner side of the inner upper cover 2 is provided with inner upper cover internal threads 22 corresponding to the bottle mouth threads 41, the outer side of the inner upper cover 2 is provided with inner upper cover external threads 21, and a retaining hoop 23 is arranged above the inner upper cover external threads 21.
The inner side of the outer upper cover 1 is provided with an outer upper cover thread 11 corresponding to the inner upper cover external thread 21, and a backstop buckle 12 is arranged above the outer upper cover thread 11.
The inner upper cover 2 is rotatably connected to the outer side of the bottle mouth 4.
The outer upper cover 1 is rotatably connected to the outer side of the inner upper cover 2, and when the outer upper cover is rotated in place, the anti-back buckle 12 is buckled below the anti-back hoop 23. When the anti-back buckle 12 is buckled below the anti-back hoop 23, the outer upper cover 1 cannot be reversely screwed out, and the outer upper cover 1 is screwed into the inner upper cover 2, so that the mutually matched threads can prevent the outer upper cover 1 from being forcibly pulled out upwards. At this point, the outer upper cover 1 and the inner upper cover 2 cannot be separated and pulled out.
