[0002] The Chinese patent with patent application number 202323339096.8 records a bottle cap assembly and its bottle, wherein the bottle cap assembly includes a bottle cap body for being sleeved on the bottle mouth, a storage bin assembled on the bottle mouth, and a piercing part for piercing the storage bin, and is designed to achieve mixing or reaction of the substance in the bottle with the substance in the storage bin, by piercing the pierceable structure at the bottom of the storage bin through the piercing part, so that the material in the storage bin can be released and mixed with the substance in the bottle; when the bottle cap body moves upward, the storage bin can also be driven upward by the bottle cap body.

[0003] However, after being irradiated and sterilized, changes occur inside the storage bin material, making the originally designed easy-to-puncture structure no longer easy to puncture, affecting the puncture effect. Utility Model Content

[0004] The utility model provides a novel bottle cap assembly and a bottle thereof, so as to solve the technical problem that a storage bin is difficult to be punctured after irradiation sterilization.

[0005] On the one hand, the utility model provides a novel bottle cap assembly, including a bottle cap body, a material storage bin and a puncture portion;

[0006] The bottle cap body is used to be sleeved on the bottle mouth;

[0007] The storage bin comprises a cavity tube portion and a bottom cover, wherein the bottom cover is detachably assembled with the bottom opening of the cavity tube portion, and a first sealing ring is assembled around the edge of the bottom cover for abutting against the bottom opening of the cavity tube portion;

[0008] The puncture portion is arranged inside the storage bin;

[0009] When the bottle cap body moves toward the bottle mouth, the bottle cap body applies pressure to the puncture portion to push the bottom cover away from the bottom of the cavity tube portion, and the bottom cover is separated from the cavity tube portion, so that the storage bin is connected to the bottle body.

[0010] The provision of the first sealing ring can not only improve the sealing performance of the storage bin, but also reduce the friction coefficient when the bottom cover and the cavity tube part move relative to each other, so that the bottom cover is easier to open after being subjected to force.

[0011] As a preferred technical solution of the utility model, the outer wall of the top of the cavity tube part is sleeved with a second sealing ring. The second sealing ring can not only improve the sealing performance of the bottle mouth, but also reduce the friction coefficient when the cavity tube part and the bottle mouth move relative to each other, so that the cavity tube part and the bottle mouth can move relative to each other more smoothly when subjected to force.

[0012] As a preferred technical solution of the utility model, the material of the storage bin can be TPU, PE, silicone, plastic, glass, ceramic or metal (such as stainless steel, aluminum products) and other materials that do not react with the substances contained in the storage bin.

[0013] As a preferred technical solution of the utility model, the material of the first sealing ring and the second sealing ring can be TPU, PE, silicone, rubber, PU (polyurethane) or PTFE (polytetrafluoroethylene) and other materials that do not react with the bottle body and the substances in the storage bin.

[0014] As a preferred technical solution of the utility model, the bottom cover is provided with a first sealing groove adapted to be assembled with the first sealing ring, and the top outer wall of the cavity tube portion is provided with a second sealing groove adapted to be assembled with the second sealing ring. This arrangement makes the assembly of the first sealing ring and the second sealing ring more convenient.

[0015] As a preferred technical solution of the utility model, the storage bin is a glass storage bin, a plastic storage bin, a ceramic storage bin or a metal storage bin.

[0016] As a preferred technical solution of the present utility model, the bottom cover is provided with a mounting groove, and the mounting groove and the piercing portion can be adapted for mounting.

[0017] As a preferred technical solution of the utility model, a piston portion is provided on the inner top wall of the bottle cap body, and the piston portion is adapted to the top inner wall of the cavity portion. When the puncturing portion pushes the bottom cover away from the cavity portion, the piston portion is connected to the cavity portion as a whole.

[0018] As a preferred technical solution of the utility model, a boss is provided on the inner top wall of the bottle cap body, and the position of the boss corresponds to the puncturing part; when the bottle cap body moves toward the bottle mouth, the boss applies pressure to the puncturing part to push the bottom cover away from the bottom of the cavity tube part.

[0019] As a preferred technical solution of the utility model, it also includes a filter part, which is arranged at the bottom of the storage bin. The filter part is used to prevent the bottom cover from falling into the bottle body after the storage bin is punctured, and is used to filter the solute in the storage bin.

[0020] On the other hand, the utility model also provides a bottle, comprising a bottle body and the above-mentioned bottle cap assembly, wherein the bottle cap assembly is assembled on the bottle body with a bottle mouth. Before the bottom cover of the storage bin is pushed away from the cavity tube part, the storage bin and the bottle mouth are tightly connected as one; when the bottom cover of the storage bin is pushed open, the cavity tube part and the bottle cap body are tightly connected as one, and when the bottle cap body is unscrewed, the storage bin and the filter part are taken away from the bottle mouth by the bottle cap body.

[0021] The beneficial effects are:

[0022] 1. The utility model provides a new bottle cap assembly that is easy to break open after irradiation sterilization. The utility model sets the material storage bin as a cavity tube part and a bottom cover. The bottom cover is detachably mounted at the bottom end of the cavity tube part. A first sealing ring is arranged around the edge of the bottom cover to abut against the cavity tube part to form a holding cavity to accommodate the raw materials. The first sealing ring can not only improve the sealing performance of the material storage bin, but also reduce the friction coefficient during relative movement between the cavity tube part and the bottom cover, so that the bottom cover is easier to open after being stressed. Even after irradiation sterilization, the performance of the first sealing ring remains unchanged, and the bottom cover is easily pushed away from the bottom of the cavity tube part under stress. The puncture of the material storage bin is achieved by separating the bottom cover from the cavity tube part under stress, which solves the technical problem of the prior art that the material storage bin is difficult to be punctured due to the degeneration of the material storage bin after near-irradiation sterilization.

[0023] 2. The bottle mouth is closed by arranging a second sealing ring on the outer wall of the top of the cavity tube part. At the same time, the second sealing ring can reduce the friction coefficient when the cavity tube part and the bottle mouth move relative to each other, so that the cavity tube part and the bottle mouth can move relative to each other more smoothly when subjected to force.

[0031] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0032] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0033] like Figure 1 , Figure 2 A novel bottle cap assembly shown includes: a bottle cap body 1, a material storage bin 2, a puncture portion 3, an anti-theft ring 5 and a filter portion 4; the bottle cap body 1 is sleeved on the bottle mouth 6 and threadedly connected with the bottle mouth 6, the material storage bin 2 can extend into the bottle mouth 6 and be assembled at the bottle mouth 6, the puncture portion 3 is used to puncture the material storage bin 2, the anti-theft ring 5 is arranged at the lower end of the bottle cap body 1, and the filter portion 4 is arranged at the lower end of the material storage bin 2. When in use, the anti-theft ring 5 is torn off, the bottle cap body 1 moves downward, the puncture portion 3 cooperates with the bottle cap body 1 to puncture the material storage bin 2, so that the material storage bin 2 is connected with the bottle body, and the filter portion 4 can prevent impurities in the storage bin 2 from entering the bottle body.

[0034] like Figure 2 As shown, the storage bin 2 is used to close the bottle mouth 6. The storage bin 2 includes a cavity tube part 21 and a bottom cover 22. The cavity tube part 21 is a cylindrical structure with openings at both ends. The bottom cover 22 is detachably arranged at the bottom of the cavity tube part 21 to close the bottom opening of the cavity tube part 21. The edges of the bottom cover 22 are equipped with a first sealing ring 23. The bottom cover 22 equipped with the first sealing ring 23 is tightly assembled with the cavity tube part 21 to form a holding cavity to accommodate raw materials. The first sealing ring 23 is a TPU sealing ring, and can also be a sealing ring made of soft, elastic and low friction coefficient materials such as a PE sealing ring, a silicone sealing ring, a rubber sealing ring, a PU sealing ring or a PTFE sealing ring. The setting of the first sealing ring 23 can not only improve the sealing performance of the storage bin 2, but also reduce the friction coefficient when the bottom cover 22 and the cavity tube part 21 move relative to each other, so that the bottom cover 22 is easier to open after being subjected to force. The material of the storage bin 2 is TPU. Of course, the material of the storage bin 2 can also be PE, silicone, plastic, glass, ceramic or metal (such as stainless steel, aluminum products) and the like.

[0035] like Figure 3As shown, the top edge of the cavity portion 21 is provided with an edge whose outer diameter is greater than the inner diameter of the bottle mouth 6. The top outer wall of the cavity portion 21 is matched with the top inner wall of the bottle mouth 6. In order to achieve a better sealing effect, the top outer wall of the cavity portion 21 is sleeved with a second sealing ring 24. The second sealing ring 24 is a TPU sealing ring, and can also be a sealing ring made of a soft, elastic material with a low friction coefficient such as a PE sealing ring, a silicone sealing ring, a rubber sealing ring, a PU sealing ring or a PTFE sealing ring. The storage bin 2 has the function of closing the bottle mouth 6. The provision of the second sealing ring 24 can not only improve the sealing performance of the bottle mouth 6, but also reduce the friction coefficient when the cavity portion 21 and the bottle mouth 6 move relative to each other, so that the cavity portion 21 and the bottle mouth 6 can move relative to each other more smoothly when subjected to force.

[0036] In order to facilitate the assembly of the first sealing ring 23 and the second sealing ring 24 (hereinafter referred to as the sealing ring), a sealing groove is provided at the position where the sealing ring needs to be assembled (that is, the bottom cover 22 is provided with a first sealing groove that is matched and assembled with the first sealing ring 23, and the top outer wall of the cavity tube part 21 is provided with a second sealing groove that is matched and assembled with the second sealing ring 24), and the shapes and sizes of the sealing grooves and sealing rings that are matched and assembled match each other.

[0037] like Figure 2 As shown, the piercing portion 3 is arranged inside the storage bin 2, and a mounting groove 25 is arranged on the bottom cover 22 for assembling the piercing portion 3. In other embodiments, the piercing portion 3 and the bottom cover 22 can also be arranged as an integrally formed structure; or the piercing portion 3 can also be fixed to the inner wall of the cavity tube portion 21 by a deformable cantilever, and at least two cantilever arms are arranged. Of course, the piercing portion 3 can also be assembled on the top wall of the bottle cap body 1 or be integrally formed with the top wall of the bottle cap body 1.

[0038] like Figure 2 As shown, the inner top wall of the bottle cap body 1 is provided with a piston portion 11 and a boss 12, the piston portion 11 is adapted to the top of the cavity portion 21, when the bottom cover 22 is pushed away from the bottom of the cavity portion 21 (i.e. the storage bin 2 is broken open, the storage bin 2 is connected with the bottle body), the piston portion 11 enters the cavity portion 21 and is tightly connected with the top of the cavity portion 21, and the bottle cap body 1 is unscrewed, and the piston portion 11 will drive the cavity portion 21 away from the bottle mouth 6. The boss 12 is arranged corresponding to the puncture portion 3, and the boss 12 is used to cooperate with the puncture portion 3 to break the bottom cover 22 of the storage bin 2.

[0039] like Figure 2 As shown, the filter unit 4 is fixedly arranged at the lower end of the storage bin 2, and the filter unit 4 is a filter net, filter cotton, ultrafiltration membrane or other materials that can achieve filtering effect. The filter unit 4 is used to prevent the bottom cover 22 from falling into the bottle body after the storage bin 2 is punctured, and is used to filter the solute in the storage bin 2. Of course, in other embodiments, the filter unit 4 can also be omitted.

[0040] In other embodiments, in order to increase the sealing performance of the storage bin 2, a sealing layer is provided at the top opening of the storage bin 2, and the sealing layer is tin sealing paper, or aluminum foil or other materials that can ensure that the contents of the storage bin 2 are protected from the external environment.

The bottle cap body 1 is tightly connected with the cavity part 21 through the piston part 11. Shake the bottle to fully mix or react the storage bin 2 with the material in the bottle body before use. Unscrew the bottle cap body 1, and the storage bin 2 and the filter part 4 are taken away from the bottle mouth 6 by the bottle cap body 1.

[0042] In other embodiments, the cavity portion 21 is only provided with an opening at the bottom, the sealing layer is made of a material with elastic deformation ability, and the puncture portion 3 is fixed or assembled with the sealing layer. When in use, the bottle cap body 1 moves toward the bottle mouth 6, driving the boss 12 to apply pressure to the puncture portion 3, and the bottom cover 22 is separated from the cavity portion 21 after being stressed, so that the storage bin 2 is connected to the bottle body. In order to enable the cavity portion 21 to be tightly connected to the bottle cap body 1 as a whole after the bottom cover 22 is separated, a part of space is reserved at the top of the cavity portion 21 for the piston portion 11 to enter.

[0043] Obviously, this embodiment also relates to a bottle, comprising a bottle body and the above-mentioned bottle cap assembly, wherein the bottle cap assembly is assembled on the bottle body with a bottle mouth 6.
