[0032] The present invention will be further described below in conjunction with the accompanying drawings:

[0033] Example 1: Figures 1 to 2As shown, a container cover comprises a base 1 which can be connected to the container mouth and a cover 2 which can move relative to the base 1, wherein the cover 2 comprises a cover body 21 connected to the base 1 and an upper cover 22 which can close or open the cover body 21, wherein the base 1 is provided with a liquid outlet 11 which is connected to the interior of the container, and the base 1 is provided with a sealing member 12 which closes the liquid outlet 11 and can be torn to open the liquid outlet 11, and the upper cover 22 is provided with a pressing column 221 which can press and tear the sealing member 12 when the cover 2 moves downward relative to the base 1, and a locking device 3 which can lock the position of the cover body 21 after the pressing column 221 pushes off the sealing member 12 is provided between the cover body 21 and the base 1. The lid 2 can move downward relative to the base 1, and the upper cover 22 moves with the lid 2 so that the pressing column 221 moves downward to press the tearing seal 12. There is no need to pull the pull ring. The method of tearing the seal 12 is simpler and does not require contact with the lid 2. It is more hygienic. After the lid body 21 moves downward, it is locked by the locking device 3. The lid 2 cannot be detached from the base 1, and the problem of losing the lid 2 will not occur.

[0034] The locking device 3 comprises a protrusion 31 disposed on the cover body 21 , and the base 1 is provided with a protrusion ring 32 which can be buckled with the protrusion 31 to prevent the cover body 21 from moving upward.

[0035] A positioning ring 33 is provided on the base 1 and above the convex ring 32. A positioning groove 34 that can cooperate with the protrusion 31 is formed between the positioning ring 33 and the convex ring 32. When the cover 21 moves downward, the protrusion 31 is separated from the positioning groove 34 and moves to the bottom of the convex ring 32 and is buckled by the convex ring 32. The positioning groove 34 is used to position the protrusion 31. The convex ring 32 and the protrusion 31 are buckled and fixed to each other to prevent the cover 21 from being separated from the base 1.

[0036] The upper surface of the convex ring 32 is an inclined surface 321. In the present invention, the upper surface of the convex ring 32 is an inclined surface 321, which can make it easier for the cover body 21 to move downward relative to the base 1, so that the pressing column 221 can press the tear seal 12 more easily.

[0037] A flexible connecting belt 23 is also provided between the upper cover 22 and the cover body 21 for connecting the two and enabling the upper cover 22 to be opened relative to the cover body 21. The upper cover 22 and the cover body 21 are connected by the flexible connecting belt 23 to prevent the upper cover 22 from being lost.

[0038] The base 1 is provided with a buckle 14, and the upper cover 22 is provided with a slot 222 that is engaged with the buckle 14 so that the upper cover 22 closes the cover body 21. In this embodiment, the buckle 14 and the slot 222 are engaged so that the upper cover 22 closes the cover body 21, thereby preventing external debris from entering the container through the liquid outlet 11 from behind the cover body 21 and contaminating the product in the container.

[0039] The present invention is assembled on the mouth of the container when in use. When the present invention is in the initial state, the protrusion 31 on the lid 2 of the present invention is arranged in the positioning groove 34, and a positioning ring 33 is arranged above the protrusion 31. The positioning ring 33 prevents the protrusion 31 from moving upward, and the lid 2 cannot move upward relative to the base 1 and cannot be removed from the base 1, which limits the lid 2 to only move downward relative to the base 1; when the lid 2 moves downward relative to the base 1, the pressing column 221 on the upper cover 22 moves downward and presses the tearing seal 12, and the protrusion 31 on the lid 2 moves downward and disengages from the positioning groove 34 and moves to the bottom of the protruding ring 32 and is buckled by the protruding ring 32, and the protruding ring 32 prevents the protruding portion 31 from moving upward, and the lid 2 cannot be detached from the base 1.

[0040] Working principle: When the present invention is used, the lid 2 is pressed, and the lid 2 moves downward relative to the base 1. The upper cover 22 moves with the lid 2 so that the pressure column 221 moves downward to press the tearing seal 12. The protrusion 31 on the cover body 21 moves downward, disengages from the positioning groove 34, moves to the bottom of the convex ring 32 and is buckled by the convex ring 32. The upper cover 22 is turned over and the cover body 21 is opened. The product in the container can flow out through the liquid outlet 11. When the product does not need to be poured, the upper cover 22 and the cover body 21 are closed by the buckle 14 and the slot 222. At the same time, the pressure column 221 on the upper cover 22 closes the liquid outlet 11, the container cannot discharge liquid, and it is also ensured that external air does not enter the container.

[0041] Example 2: Figures 3 to 5 As shown, the difference between this embodiment and embodiment 1 is that:

[0042] The base 1 is also provided with a groove 15, and the upper cover 22 is also provided with a clamping block 223 that is plugged into the groove 15 so that the upper cover 22 closes the cover body 21. In this embodiment, the groove 15 and the clamping block 223 are clamped to make the upper cover 22 close the cover body 21, thereby preventing external debris from entering the cover body 21 and then entering the container through the liquid outlet 11 to contaminate the product in the container.

[0043] The base 1 is also provided with an internal thread 13, and the cover 21 is provided with an external thread 211 that matches the internal thread 13. The base 1 has an internal thread 13, and the cover 21 is provided with an external thread 211 that matches the internal thread 13, so that the rotating cover 21 moves downward relative to the base 1 more smoothly.

[0044] Working principle: When the present invention is used, the lid 2 is rotated and the lid 2 moves downward relative to the base 1. The upper cover 22 moves along with the lid 2 so that the pressure column 221 moves downward to press the tearing seal 12. The protrusion 31 on the cover body 21 moves downward, disengages from the positioning groove 34, moves to the bottom of the convex ring 32 and is engaged by the convex ring 32. The upper cover 22 is turned over and the cover body 21 is opened. The product in the container can flow out through the liquid outlet 11. When the product does not need to be poured out, the upper cover 22 and the cover body 21 are closed by the engagement of the engaging block 223 and the groove 15. The pressure column 221 on the upper cover 22 closes the liquid outlet 11, and the container cannot discharge liquid.

[0045] Example 3: Figures 6 to 7 As shown, the difference between this embodiment and embodiment 2 is that:

[0046] The base 1 is also provided with at least two groups of internal thread segments 132, and the upper cover 22 is provided with external thread segments 220 that cooperate with the internal thread segments 132. A first space 2121 is formed between adjacent external thread segments 220, and a second space 131 is formed between adjacent internal thread segments 132. When the internal thread segments 132 are aligned with the first space 2121 and the external thread segments 220 are aligned with the second space 131, the upper cover 22 can open the cover body 21. In this embodiment, the upper cover 22 and the cover body 21 are not closed by the groove 15 and the clamping block 223, but the upper cover 22 closes the cover body 21 by the cooperation of the internal thread segments 132 and the external thread segments 220. When the internal thread segments 132 are aligned with the first space 2121 and the external thread segments 220 are aligned with the second space 131, the top pressure column 221 can be separated from the liquid outlet 11, the liquid outlet 11 is opened, and the product in the container can be poured out from the liquid outlet 11.

[0047] Working principle: In the initial state of the present invention, the internal thread section 132 is meshed with the external thread section 220, the lid 2 is rotated, the lid 2 moves downward relative to the base 1, and the upper cover 22 follows the lid 2 to move downward so that the pressure column 221 moves downward to press the tearing seal 12, and the protrusion 31 on the cover body 21 moves downward, disengages from the positioning groove 34 and moves to the bottom of the convex ring 32 and is buckled by the convex ring 32. At this time, the internal thread section 132 is disengaged from the external thread section 220, and the internal thread section 132 is aligned with the first empty position 2121 and the external thread section 220 is aligned with the second empty position 131. At this time, the upper cover 22 can be turned over to disengage the pressure column 221 from the liquid outlet 11, and the cover body 21 is opened. The product in the container can flow out through the liquid outlet 11. When the product does not need to be poured, the cover body 21 is rotated so that the internal thread section 132 is meshed with the external thread section 220, ensuring that the upper cover 22 is firmly connected to the cover body 21 and the container cannot discharge liquid.

[0048] Example 4: Figures 8 to 11As shown, the difference between this embodiment and the embodiment 3 is that: the base 1 is further provided with a groove 15, and the upper cover 22 is further provided with a clamping block 223 that is plugged into the groove 15 so that the upper cover 22 closes the cover body 21. In this embodiment, the groove 15 and the clamping block 223 are clamped to make the upper cover 22 close the cover body 21, so as to prevent external debris from entering the container through the liquid outlet 11 from behind the cover body 21 and contaminating the product in the container.

[0049] The base 1 is provided with a buckle 14, and the upper cover 22 is provided with a slot 222 that is engaged with the buckle 14 so that the upper cover 22 closes the cover body 21. In this embodiment, the buckle 14 and the slot 222 are engaged so that the upper cover 22 closes the cover body 21, thereby preventing external debris from entering the container through the liquid outlet 11 from behind the cover body 21 and contaminating the product in the container.

[0050] Working principle: In the initial state of the present invention, the internal thread section 132 is meshed with the external thread section 220, the lid 2 is rotated, the lid 2 moves downward relative to the base 1, and the upper cover 22 moves downward with the lid 2 so that the pressure column 221 moves downward and presses the tearing seal 12, and the protrusion 31 on the cover body 21 moves downward and disengages from the positioning groove 34 and moves to the bottom of the convex ring 32 and is buckled by the convex ring 32. At this time, the internal thread section 132 is disengaged from the external thread section 220, and the internal thread section 132 is aligned with the first empty position 2121 and the external thread section 220 is aligned with the second empty position 131. At this time, the upper cover 22 can be flipped over to disengage the pressure column 221 from the liquid outlet 11, and the cover body 21 is opened, and the product in the container can flow out through the liquid outlet 11. When there is no need to pour the product, the upper cover 22 is rotated close to the cover body 21, and the buckle 14 and the slot 222 are engaged to close the upper cover 22 and the cover body 21. At the same time, the engaging block 223 and the groove 15 are engaged to close the upper cover 22 and the cover body 21. At this time, the cover body 21 can also be rotated so that the internal thread section 132 is engaged with the external thread section 220, ensuring that the upper cover 22 and the cover body 21 are more firmly connected, with triple closure and better sealing effect.
