[0021] The utility model is further described below with reference to the accompanying drawings:

[0022] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions in the accompanying drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0023] This embodiment provides a detachable bottle cap with a safety structure, such as Figure 1 and Figure 2As shown, bottle A is a general plastic beverage bottle, generally with a cylindrical mouth and a thread on the outer wall. Of course, the product of this embodiment is also applicable to bottles of other types of products, such as liquid seasoning bottles for cooking, cosmetics or cleaning products, etc. Figures 1 to 4 As shown, the detachable bottle cap includes an outer sleeve 1 for connecting to the bottle body A, the top of the outer sleeve 1 is open, and a storage barrel 2 is provided in the outer sleeve 1 which is inserted into the outer sleeve 1 from top to bottom, and the bottom of the storage barrel 2 is open. A sealing structure 11 is provided at the bottom of the outer sleeve 1 which can seal the bottom of the outer sleeve 1, and an adjusting structure 3 for adjusting the up and down movement of the storage barrel 2 is provided between the outer sleeve 1 and the storage barrel 2. When the storage barrel 2 moves downward, the sealing structure 11 seals the bottom of the outer sleeve 1 so that the inner cavity of the storage barrel 2 constitutes a storage chamber 20 for storing auxiliary materials. When the storage barrel 2 moves upward, the bottom of the storage barrel 2 is open so that the auxiliary materials in the storage chamber 20 can be taken out. The lower end of the storage barrel 2 flows out, and the top of the storage barrel 2 is connected to a top cover 4 for closing the top thereof, and a threaded structure 5 is provided between the top cover 4 and the storage barrel 2, which can enable the top cover 4 to be screwed onto the storage barrel 2 in the forward direction, and a first tearable structure 401 is provided in the middle of the top cover 4 and is circumferentially arranged around it. The first tearable structure 401 divides the top cover 4 into a top cover body 41 and a first safety ring 42 connected to the lower side of the top cover body 41, so that the first safety ring 42 can be torn apart from the top cover body 41, and a first one-way locking structure 6 is further provided between the first safety ring 42 and the storage barrel 2, which can prevent the first safety ring 42 from rotating reversely relative to the top cover body 41, wherein, as Figure 2 As shown, the forward direction is the clockwise direction when viewed from top to bottom in the drawing, and the reverse direction is the counterclockwise direction when viewed from top to bottom in the drawing. Of course, the forward and reverse directions can also be reversed without affecting use. After the product is produced, the bottle cap is put on the bottle body A. When the user uses it normally, the top cover 4 is rotated counterclockwise, and the first one-way locking structure 6 prevents the first safety ring 42 from rotating reversely relative to the top cover body 41, so that the entire storage barrel 2 rotates counterclockwise and the top cover 4 cannot be opened. However, in special circumstances, such as bottle cap recycling, it is necessary to clean the remaining liquid in the storage barrel 2 and separate the top cover 4 from other structures. At this time, the top cover body 41 is rotated reversely until it reaches the limit position, and then rotated reversely with force, so that the first tearable structure 401 between the first safety ring 42 and the top cover body 41 can be torn, thereby separating the first safety ring 42 from the top cover body 41. The torn top cover body 41 indicates that the storage chamber 20 has been opened, thereby playing a safety role and facilitating later recycling.

[0024] like Figure 4As shown, the detailed structure of the first one-way locking structure 6 is that the first one-way locking structure 6 includes a first inner ratchet 601 arranged on the inner side of the first safety ring 42, and a first outer ratchet 602 arranged on the outer surface of the storage barrel 2 and matching the first inner ratchet 601. The first inner ratchet 601 protrudes toward a circle and is inclined in a counterclockwise direction, and the shape of the first outer ratchet 602 can match it. It belongs to conventional technology and will not be elaborated on. The main purpose is that this structure is reliable and stable.

[0025] As a preference, Figures 1 to 4 As shown, the outer surface of the storage barrel 2 is further provided with a blocking portion 21 for blocking the first safety ring 42 from moving upward. When the top cover 4 is connected to the storage barrel 2, the first inner ratchet 601 is located on the lower side of the blocking portion 21. In this way, after the first tearable structure 401 between the first safety ring 42 and the top cover body 41 is torn, the blocking portion 21 can prevent the first safety ring 42 from detaching upward, thereby leaving the first safety ring 42 on the storage barrel 2.

[0026] Preferably, the first tearable structure 401 is a thin wall or a cut, a thin wall, that is, a region circumferentially surrounding the top cover 4, where the wall thickness is thinner; a cut, in this embodiment, the first tearable structure 401 adopts a cut structure, such as Figure 4 As shown, a notch is opened around the top cover 4 along the circumference, and the first safety ring 42 and the top cover body 41 are connected by a small connecting strip 402.

[0027] like Figures 2 to 4 As shown, the bottom of the outer sleeve 1 is provided with a second tearable structure 101 circumferentially arranged around it, and the second tearable structure 101 divides the outer sleeve 1 into a sleeve body 12 and a second safety ring 13 connected to the lower side of the sleeve body 12, so that the second safety ring 13 can be torn and separated from the sleeve body 12, and the second internal ratchet 801 is provided on the second safety ring 13, and the second internal thread 701 is provided on the sleeve body 12. The sleeve body 12 and the bottle body A are also connected by providing a second threaded structure 7, and the inner wall of the sleeve body 12 is provided with a second internal thread 701 for screwing it forward on the bottle body A, and the bottle body A is provided with a corresponding second internal thread 702. The second safety ring 13 and the bottle body A are also provided with a second one-way locking structure for preventing the second safety ring 13 from rotating reversely relative to the bottle body A, including a second internal ratchet 801 provided on the second safety ring 13, and a second external ratchet 802 provided on the bottle body A. The second tearable structure 101 may have the same structure as the first tearable structure 401 .

[0028] In order to improve the airtightness of the structure and ensure that the liquid in the storage chamber 20 does not leak out, Figures 2 to 4As shown, a sealing convex ring 22 capable of resting against the inner wall of the outer sleeve 1 is further provided on the outer wall of the storage barrel 2 .

[0029] like Figures 1 to 4 As shown, the adjustment structure 3 comprises a spiral adjustment groove 301 provided on the outer sleeve 1 and a clamping post 302 provided on the storage barrel 2 and inserted into the adjustment groove 301. Thus, the storage barrel 2 can be moved upward or downward by simply rotating the storage barrel 2, and the adjustment groove 301 and the clamping post 302 cooperate to enable the storage barrel 2 to rotate. Of course, a conventional threaded connection structure can also be used.

[0030] As a preference, Figures 2 to 4 As shown, the sealing structure 11 includes a sealing platform 111 arranged at the bottom of the outer sleeve 1 and protruding upward, and the outer sleeve 1 is provided with a sealing ring 112 surrounding the sealing platform 111. An annular sealing groove 110 for accommodating the lower end of the storage barrel 2 is formed between the sealing platform 111 and the sealing ring 112. In this way, when the storage barrel 2 moves downward, the annular opening at the lower end of the storage barrel 2 is inserted into the sealing groove 110 to form a sealing structure, so that the lower side of the storage chamber 20 is sealed, further improving the sealing performance.
