[0021] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0022] This embodiment provides a detachable bottle cap, such as Figure 1-5As shown, it includes an upper cover 1, a sealing column 2 and a main body 3; the main body 3 is hollow inside, and its interior is divided into an upper inner cavity 5 and a lower inner cavity 6 by a partition plate 4; the lower inner cavity 6 is used to connect with the bottle mouth of the bottle body; the partition plate 4 is provided with a through hole 7 for connecting the upper inner cavity 5 and the lower inner cavity 6; the lower end 21 of the sealing column 2 extends into the upper inner cavity 5 and can be detachably inserted into the through hole 7 to form a seal for the through hole 7; the top of the upper inner cavity 5 is provided with an opening 8, and the upper cover 1 can detachably cover the opening 8.

[0023] In this embodiment, the inner wall of the lower inner cavity 6 is provided with an internal thread 9 for threaded connection with the bottle mouth of the bottle body.

[0024] In this embodiment, the through hole 7 is funnel-shaped, and the lower end 21 of the sealing column 2 matches the shape and size of the through hole 7 .

[0025] In this embodiment, the upper inner wall of the upper inner cavity 5 is provided with an internal thread 10, and the lower outer wall of the upper cover 1 is provided with a matching external thread 11. The lower part of the upper cover 1 extends into the upper inner cavity 5 from the opening 8, and the lower inner wall of the upper cover 1 and the upper inner wall of the upper inner cavity 5 are fixedly connected by threads.

[0026] In this embodiment, a sealing locking structure is provided on the top of the partition plate 4, and the sealing locking structure includes a C-shaped locking groove 12, one end of which is closed and the other end is open; a locking block 13 is provided on the outer surface of the sealing column 2, and when the lower end 21 of the sealing column 2 is inserted into the through hole 7, the locking block 13 can enter or leave the interior of the C-shaped locking groove 12 through the rotation of the sealing column 2.

[0027] It should be noted that, by providing the C-shaped locking groove and the locking block, the sealing column can be locked by rotating after the lower end of the sealing column is inserted into the through hole, so that it cannot move up and down, thereby preventing the sealing column from loosening and affecting the sealing effect during product transportation and movement. The closure of one end of the C-shaped locking groove 12 can limit the locking block 13. When the locking block 13 is screwed into the C-shaped locking groove 12 and its other end abuts against one end of the C-shaped locking groove 12, it indicates that the sealing column has been rotated into place and the locking is completed.

[0028] More specifically, in this embodiment, the sealing locking structure further includes a limit block 14. When the sealing column 2 rotates until one end of the locking block 13 abuts against the limit block 14, the locking block 13 completely leaves the C-shaped locking groove 12. When the consumer wants to unlock the sealing column, the sealing column is rotated in the opposite direction. When the consumer feels the limit block blocking the locking block, the sealing column is known to have been rotated into place. At this time, the sealing column can be lifted upward to make the lower end 21 of the sealing column 2 leave the through hole 7.

[0029] More specifically, in this embodiment, the partition plate 4 is stepped, the C-shaped locking groove 12 is arranged on the lower step, and the limit block 14 is arranged on the upper step; the upper step and the lower step are transitionally connected by a slope structure 18; one end of the locking block 13 has an inclined surface 19 that matches the slope structure 18.

[0030] In the process of reverse rotation of the sealing column to unlock, the locking block 13 is first screwed out of the C-shaped locking groove 12. As the sealing column continues to rotate, one end of the locking block 13 reaches the position of the inclined surface structure. At this time, the inclined surface at one end of the locking block 13 contacts the inclined surface structure, and as the sealing column continues to rotate, the inclined surface moves up along the inclined surface structure. The locking block 13 gradually reaches the upper step and one end of it abuts against the limit block 14, and the process of unlocking the sealing column is completed. The interaction between the inclined surface and the inclined surface structure can provide assistance for the lifting of the sealing column, which is easier to achieve and saves effort than directly lifting the sealing column upward. During the process of the lower end of the sealing column being inserted into the through hole, if the locking block 13 first abuts against the upper step, the locking block 13 can reach the position of the lower step by rotating the sealing column, and continue to rotate the sealing column until the locking block 13 is screwed into the C-shaped locking groove 12.

[0031] In this embodiment, a sealing column slot 15 is provided at the bottom of the upper cover 1 , and the upper end of the sealing column 2 can be detachably inserted into the sealing column slot 15 .

[0032] More specifically, the inner wall of the sealing column slot 15 is provided with a guide column 16, and the upper outer wall of the sealing column 2 is provided with a guide groove 17, and the guide column 16 can be inserted into the guide groove 17. In this way, the sealing column and the upper cover can rotate synchronously, and when the sealing column rotates to the locking direction to the right position, the upper cover is just connected and locked with the upper inner cavity thread, and when the sealing column rotates to the unlocking direction to the right position, the upper cover is just unlocked with the upper inner cavity.

[0033] In this embodiment, the C-shaped locking groove 12, the locking block 13, the limiting block 14, the inclined surface structure 18, the guide column 16, the guide groove 17, etc. are all arranged in pairs.

[0034] During production, the sealing column and the main body are assembled first, and the lower end of the sealing column seals the through hole, and then the solid or liquid additives are filled into the upper inner cavity, and then the upper end of the sealing column and the upper cover are assembled, so that the upper cover is closed on the opening of the upper inner cavity, and the upper cover is rotated to be threadedly connected and locked with the main body, and the locking block of the sealing column is also screwed into the C-shaped locking groove, completing the position locking of the sealing column. When drinking, the sealing column is rotated in the opposite direction to release the lock of the sealing column, and the connection between the upper cover and the main body is also released, so that the sealing column is lifted upward, and the through hole is no longer sealed. At this time, the solid or liquid additives can enter the bottle through the through hole, and it can be drunk after shaking.

[0035] For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and concepts, and all of these changes and modifications should be included in the protection scope of the claims of the utility model.
