[0027] Preferably, the cover body 1 includes an upper sealing cover 101, and the cover body 2 includes a lower connecting cover 201 and an inner cylinder 202 connected to the lower connecting cover 201 and located inside the lower connecting cover 201;

[0028] Preferably, the top of the inner cylinder 202 is higher than the top of the lower connecting cover 201, and the lower connecting cover 201, the inner cylinder 202 and the connecting position between the lower connecting cover 201 and the inner cylinder 202 form a trough 207 for receiving liquid.

[0029] Preferably, the top end of the inner cylinder 202 is bent outward to form an arc-shaped curling edge 2021 , and the arc-shaped curling edge 2021 is located above the groove body 207 .

[0030] Each time the liquid is poured out and put back into the bottle, the arc-shaped curled edge 2021 can play a certain role in guiding and draining the liquid, so that the liquid is guided to drip into the groove body 207, and the liquid is collected by the groove body 207, thereby reducing the outflow of liquid when the lid is closed.

[0031] Preferably, the outer edge of the upper sealing cover 101 protrudes outward to form a cover-push-out boss 103 , and the outer edge of the lower connecting cover 201 is recessed inward to form a cover-push-out recess 209 corresponding to below the cover-push-out boss 103 .

[0036] By pulling the pull ring 206 under the action of external force, the tear sheet 205 can be separated from the sealing sheet 203 along the pull groove 204, thereby leaking out the liquid outlet, so as to pour out the liquid in the bottle.

[0037] Preferably, the inner diameter of the upper section of the inner tube 202 located at the upper end of the sealing sheet 203 is larger than the inner diameter of the lower section located at the lower end of the sealing sheet 203, so as to cooperate with the bottle body and fully fit the bottle body.

[0038] Preferably, the outer wall diameter of the lower section of the inner cylinder 202 is tapered, and a connecting protrusion 208 is provided on the inner wall of the lower connecting cover 201 at a position corresponding to the reduced diameter of the outer wall of the inner cylinder 202, which cooperates with the bottle body and fully fits the bottle body to achieve a stable connection with the bottle body.
