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

[0033] Embodiment 1, as Figures 1 to 8 As shown, a sealed rotary cover comprises a seat body 1 and a cover body 2 which can rotate relative to the seat body 1, the seat body 1 is provided with a liquid outlet 11 connected to a container, the cover body 2 is provided with a flow outlet 21 which can be connected to the liquid outlet 11 and pour out liquid when the cover body 2 rotates, the seat body 1 is also provided with an air inlet 12 and a flow hole 13 connected to the liquid outlet 11 and used to pour out liquid, and an air supplement channel 14 which is connected to the air inlet 12 is formed between the cover body 2 and the seat body 1. The present invention controls the flow outlet to connect the liquid outlet 11, the air inlet 12 and the flow hole 13 with the outside of the container by rotating the cover body 2, the product in the container can flow to the liquid outlet 11 through the flow hole 13 and then pour out, and the external air can enter the container from the air inlet 12 through the air supplement channel 14, so as to ensure that the product is poured evenly and smoothly. When using the present invention, there is no need to separate the cover body from the seat body, which can prevent the cover body from being lost, and the present invention also has the advantages of simple operation and convenient use.

[0034] A control structure is provided between the base body 1 and the cover body 2 , which can close or open the air inlet 12 and the flow hole 13 when the cover body 2 rotates relative to the base body 1 .

[0035] The control structure includes a closing piece 31 disposed on the cover body 2 and closing or opening the air inlet 12 and the flow hole 13 when the cover body 2 rotates. The closing piece 31 can close or open the air inlet 12 and the flow hole 13 when rotating, so that the present invention has better sealing performance.

[0036] The circulation hole 13 is provided with a sealing sheet 131 which can be torn by the closing sheet 31 when the cover body 2 rotates. The sealing sheet 131 is used to seal the circulation hole 13, has good sealing performance, and can be removed by rotating the closing sheet 31, and the removal method is simple.

[0037] The air inlet 12 is provided with a sealing column 121 that can be torn by the closing sheet 31 when the cover body 2 rotates, and the flow hole 13 is provided with a sealing sheet 131 that can be torn by the closing sheet 31 when the cover body 2 rotates. The sealing column 121 and the sealing sheet 131 can be used to seal the air inlet 12 and the flow hole 13, have good sealing performance, and can be removed by rotating the closing sheet 31, and the removal method is simple.

[0038] When the outflow port 21 is aligned with the liquid outlet 11, the liquid outlet 11, the air inlet 12 and the circulation hole 13 are all connected to the outside of the container, and when the outflow port 21 is misaligned with the liquid outlet 11, the cover body 2 closes the liquid outlet 11. When the present invention is used, the cover body 2 is rotated to align the outflow port 21 with the liquid outlet 11, and the closing piece 31 rotates with the cover body 2 and opens the air inlet 12 and the circulation hole 13 at the same time, so that the liquid outlet 11, the air inlet 12 and the circulation hole 13 are all connected to the outside of the container. At this time, the liquid in the container can be poured out, and the cross-sectional area of ​​the liquid outlet 11, the air inlet 12 and the circulation hole 13 is controlled by rotating the cover body 2 and the closing piece 31 to control the liquid output of the product.

[0039] When the liquid is not poured, the cover body 2 is rotated, and the closing piece 31 rotates with the cover body 2. When the outflow port 21 is misaligned with the liquid outlet 11, the closing piece 31 blocks the air inlet 12 and the flow hole 13. When the air inlet 12 and the flow hole 13 are blocked by the closing piece 31, the gas in the air replenishing channel 14 cannot enter the container through the air inlet 12 and the flow hole 13, and will not affect the quality of the product in the container.

[0040] like Figure 3 and Figure 4 As shown, the base body 1 is provided with a protrusion 15, and the base body 1 is also provided with a tearable anti-counterfeiting sheet 4 that cooperates with the protrusion 15 to limit the rotation of the cover body 2. The present invention can prevent counterfeiting by observing whether the tearable anti-counterfeiting sheet 4 is removed.

[0041] like Figure 1 , Figure 5 ,and Figure 7 As shown, the cover body 2 is provided with a clamping portion 22 which is clamped with the base body 1 .

[0042] like Figure 1 , Figure 5 ,and Figure 7 As shown, the cover body 2 is further provided with a transmission part 23 which is engaged with the closing piece 31 and drives the closing piece 31 to rotate relative to the base body 1 .

[0043] Working principle:

[0044] When the present invention is used, the tearable anti-counterfeiting film 4 is first removed, and then the cover body 2 is rotated. When the cover body 2 rotates, the sealing film 131 and the sealing column 121 are torn, and the cover body 2 continues to be rotated until the outflow port 21 is aligned with the liquid outlet 11. During this process, the closing film 31 rotates with the cover body 2, and when the outflow port 21 is aligned with the liquid outlet 11, the closing film 31 does not block the air inlet 12 and the circulation hole 13, so that the liquid outlet 11, the air inlet 12 and the circulation hole 13 are all connected to the outside of the container. After the product in the container flows to the liquid outlet 11 through the circulation hole 13, it is poured out from the liquid outlet 11. The present invention can control the cross-sectional area of ​​the liquid outlet 11 and the circulation hole 13 by rotating the cover body 2 and the closing film 31, thereby controlling the liquid output of the product.

[0045] When the present invention is closed, the cover body 2 is rotated to displace the outflow port 21 from the liquid outlet 11, and the liquid outlet 11 is closed. The closing piece 31 rotates with the cover body 2, and when the outflow port 21 is displaced from the liquid outlet 11, the closing piece 31 blocks the air inlet 12 and the flow hole 13. When the air inlet 12 and the flow hole 13 are blocked by the closing piece 31, the gas in the air replenishment channel 14 cannot enter the container through the air inlet 12 and the flow hole 13. During use, the cover body 2 does not need to be separated from the base body 1, which can prevent the cover body 2 from being lost or falling.

[0046] Embodiment 2: The difference between this embodiment and embodiment 1 is that: Figures 9 to 10 As shown, the base body 1 is provided with a tearable anti-counterfeiting wall 5 which is squeezed and torn when the cover body 2 rotates. Anti-counterfeiting is performed by observing whether the tearable anti-counterfeiting wall 5 is squeezed and torn by the cover body 2.

[0047] Example 3: Fig.11 As shown, the difference between this embodiment and embodiment 2 is that the size of the anti-counterfeit wall 5 in this embodiment is different from the length of the anti-counterfeit wall 5 in embodiment 2.
