The utility model provides an inner plug and a penetration plug for the bottle cap, and the bottle is filled with one material and the inner plug is filled with another material, thereby isolating the two materials from each other. When in use, the inner plug is pierced by twisting the plug through the safety lock cover, so that the material inside the inner plug falls into the bottle, and the two materials are mixed and reused, which can greatly extend the shelf life of the product.

[0003] The above technical solution has the following technical defects: the sealing performance of the inner plug for storing materials is not enough, which makes the materials in the inner plug easily affected by moisture, affecting its shelf life and quality of use. Utility Model Content

[0004] The utility model provides a sealed bottle cap assembly and a bottle thereof, so as to solve the technical problem that the sealing performance of the existing bottle cap material storage bin is not good.

[0005] In order to solve the above problems, the utility model provides a sealed bottle cap assembly, which adopts the following technical solutions:

[0006] A sealed bottle cap assembly, comprising a material storage bin and a bottle cap body, wherein the bottle cap body is used to be sleeved on a bottle mouth, the material storage bin is provided with an inner cavity and an open opening connected with the inner cavity; the material storage bin can extend into the bottle mouth, a sealing layer is provided at the open opening to seal the material in the inner cavity of the material storage bin, and a puncture portion is provided in the material storage bin;

[0007] When the bottle cap body moves toward the bottle mouth, the bottle cap body applies pressure to the puncturing portion to puncture the material storage bin, so that the material storage bin is connected to the bottle body.

[0008] As a preferred technical solution of the utility model, it also includes an anti-theft ring, which is fixed to the open end of the bottle cap body, and the distance from the puncture portion to the top wall of the storage bin is less than the height of the anti-theft ring.

[0009] As a preferred technical solution of the utility model, the opening is arranged at one end of the storage bin close to the bottle mouth, and the puncture portion is arranged at the bottom of the storage bin.

[0010] As a preferred technical solution of the utility model, the storage bin is provided with an indentation area for easy puncture, and the puncture portion is arranged in the indentation area.

[0011] As another preferred technical solution of the utility model, the opening is arranged at one end of the storage bin away from the bottle mouth, and the puncture part is arranged on the top wall inside the storage bin. The top wall inside the storage bin is made of an elastic material layer, and a protrusion is arranged on the top wall inside the bottle cap body at a position corresponding to the puncture part.

[0012] As a preferred technical solution of the utility model, the open edge of the storage bin is provided with a rim whose outer diameter is larger than the inner diameter of the bottle mouth, so as to prevent the storage bin from escaping from the bottle mouth and falling into the bottle body.

[0013] As a preferred technical solution of the present utility model, one end of the puncture portion abuts against the sealing layer.

[0014] As a preferred technical solution of the utility model, a groove for matching and installing with the puncturing part is provided in the bottle cap body.

[0015] As a preferred technical solution of the utility model, a piston portion is provided in the bottle cap body, and the piston portion is matched with the inner wall of the storage bin; when the puncturing portion punctures the storage bin, the piston portion is connected to the storage bin as a whole.

[0016] As a preferred technical solution of the utility model, it also includes a filter part, and the filter part is arranged on the outer bottom surface of the storage bin.

[0017] As a preferred technical solution of the present utility model, the filter part is a filter net.

[0018] A bottle comprises a bottle body and the above-mentioned sealed bottle cap assembly, wherein the sealed bottle cap assembly is assembled on the bottle body with a bottle mouth.

[0019] Before the storage bin of the bottle is punctured, the storage bin is tightly connected to the bottle mouth as a whole; when the storage bin is punctured, the storage bin is communicated with the bottle body, and the storage bin is tightly connected to the bottle cap body as a whole.

[0020] When in use, the anti-theft ring is pulled open and the bottle cap body moves down. After the bottle cap body abuts against the puncture part, the bottle cap body continues to move down, and the puncture part is forced to puncture the storage bin. At the same time, the piston part is further pressed into the inner wall of the storage bin. At this time, the contact area between the piston part and the storage bin is much larger than the contact area between the storage bin and the bottle mouth. The friction force between the inner wall of the storage bin and the piston part is larger than the friction force between the outer wall of the storage bin and the bottle mouth. Therefore, the storage bin and the piston part are tightly fastened (that is, the storage bin and the bottle cap are tightly assembled together). When the bottle cap body moves up, the storage bin is also driven to move up.

[0021] The beneficial effects are:

[0022] The utility model has a simple structure, ingenious design and high filling efficiency: by setting the storage bin and the bottle cap body as independent split structures, the materials in the storage bin and the bottle body can be filled at the same time, without the need to complete the assembly of the storage bin and the bottle body before filling the storage bin separately. This parallel filling method greatly saves production time and significantly improves the overall filling production efficiency. The utility model has good sealing performance: by adding a sealing layer at the open end of the storage bin, it prevents external humidity or air from penetrating into the storage bin through these gaps, causing the materials in the storage bin to be damp, thereby affecting its shelf life and quality of use.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Embodiment 1:

[0033] like Figure 1-2 The sealed bottle cap assembly shown in the figure comprises: a storage bin 1, a bottle cap body 2, and an anti-theft ring 4.

[0034] The bottle cap body 2 is used to cooperate with the bottle mouth 6, and the bottle cap body 2 is sleeved on the bottle mouth 6;

[0035] The storage bin 1 is provided with an inner cavity and an open opening connected with the inner cavity. The storage bin 1 can extend into the bottle mouth 6. A sealing layer 11 is provided at the open opening to seal the material in the inner cavity of the storage bin 1. A puncture portion 3 is provided at the bottom of the storage bin 1. The puncture portion 3 is used to puncture the storage bin 1, so that the storage bin 1 is connected with the bottle body, so that the storage bin 1 is mixed with the material in the bottle body;

[0036] The anti-theft ring 4 is fixed to the open end of the bottle cap body 2, and the distance from the end of the piercing portion 3 to the top wall of the storage bin 1 is less than the height of the anti-theft ring 4;

[0037] In this embodiment, the connection between the bottle cap body 2 and the bottle mouth 6 is threaded connection.

[0038] When in use, the anti-theft ring 4 is removed, the bottle cap body 2 moves downward by rotating the thread, and the piercing portion 3 first pierces the sealing layer 11; then, the bottle cap body 2 continues to move downward, and the piercing portion 3 is forced to pierce the storage bin 1 to connect the storage bin 1 with the bottle body.

[0039] The storage bin 1 is sleeved inside the bottle mouth 6. In order to prevent the storage bin 1 from falling out of the bottle mouth 6 and into the bottle body, the open edge of the storage bin 1 is provided with a rim 13 whose outer diameter is greater than the inner diameter of the bottle mouth 6. In this embodiment, the end of the storage bin 1 near the open end is in contact with the bottle mouth 6. Of course, in other embodiments, the end of the storage bin 1 near the open end may not be in contact with the bottle mouth 6.

[0040] In this embodiment, the opening is arranged at one end close to the bottle mouth 6. The sealing layer 11 is a tin sealing paper. The entire storage bin 1 is sealed with the tin sealing paper, which completely prevents the storage bin 1 from contacting with the outside world, so that the materials in the storage bin 1 can be stored for a longer time. Of course, in other embodiments, the sealing layer 11 can also be a sealing layer 11 structure such as an aluminum film.

[0041] In order to make the bottle body and the materials in the storage bin 1 mixed evenly, the storage bin 1 is no longer sleeved inside the bottle mouth 6, thereby affecting the use of the mixed product. A piston portion 21 is provided on the inner top wall of the bottle cap body 2, and the piston portion 21 is adapted to the open mouth; when the piercing portion 3 pierces the storage bin 1, the bottle cap body 2 is tightly connected to the storage bin 1 through the piston portion 21; when the bottle cap body 2 leaves the bottle mouth 6, the storage bin 1 is connected to the bottle cap body 2 as a whole, so that the storage bin 1 is no longer sleeved on the inner wall of the bottle mouth 6, and it will follow the bottle cap body 2 to leave the bottle mouth 6.

[0042] In this embodiment, the storage bin 1 is in a cylindrical shape that is larger at the top and smaller at the bottom, and the piston portion 21 is in a circular ring shape, with an outer diameter of the circular ring being equal to or slightly larger than an open inner diameter of the storage bin 1 .

[0043] In order to facilitate puncturing the bottom of the storage bin 1 , an easily punctured indentation area 14 is provided at the bottom of the storage bin 1 , and the puncturing portion 3 is disposed in the indentation area 14 .

[0044] In this embodiment, the puncture portion 3 is set as a column structure, and the puncture portion 3 is integrally formed with the storage bin 1. In this embodiment, the end of the puncture portion 3 is set as a plane, of course, it can also be designed as a sharp point or a curved surface according to the puncture requirements. The top wall inside the bottle cap body 2 is provided with a groove 22 adapted to be installed with the puncture portion 3. The end of the puncture portion 3 abuts against the sealing layer 11.

[0045] Obviously, this embodiment also provides a bottle, including a bottle body and the above-mentioned sealed bottle cap assembly, wherein the sealed bottle cap assembly is assembled on the bottle body with a bottle mouth 6 .

[0046] Before the storage bin 1 of the bottle is punctured, the storage bin 1 is tightly connected to the bottle mouth 6; when the storage bin 1 is punctured, the storage bin 1 is connected to the bottle body, and the storage bin 1 is tightly connected to the bottle cap body 2. The bottle can be used after the storage bin 1 and the material in the bottle body are fully mixed by shaking the bottle. When the bottle cap body 2 is unscrewed, the storage bin 1 is taken away from the bottle mouth 6 by the bottle cap body 2. The bottle can separate the storage bin 1 from the material in the bottle body, and extend the shelf life of the product without adding chemical additives.

[0047] The bottle of this embodiment can also be used as a culture medium device. Traditional liquid culture medium has high storage requirements, needs to be stored and transported in a cold storage, has a short shelf life, and is prone to precipitation. Using the above-mentioned bottle as a culture medium can solve the above-mentioned problems. It is convenient and quick to use. Not only does it not require cold storage and transportation, it only needs to be stored away from light, and it is not easy to produce precipitation. In addition, the storage bin 1 has good sealing performance, which can prevent the materials in the storage bin 1 from being affected by the external environment.

[0048] Embodiment 2:

[0049] The main difference between it and Example 1 is:

[0050] In this embodiment, a filter portion is provided at the lower end of the storage bin 1, which is used to prevent the cap from falling into the bottle body after being punctured, and to filter impurities in the storage bin 1, such as plastic particles that may fall from the indentation area 14.

[0051] The filter part is a filter screen.

[0052] Embodiment 3:

[0053] The main difference between it and Example 1 is:

[0054] In this embodiment, if Figure 3 As shown, the open end of the storage bin 1 is arranged at the end away from the bottle mouth 6. The piercing portion 3 is arranged in the storage bin at the end near the bottle mouth. The inner cavity of the storage bin 1 is composed of a storage barrel and a storage cover, and the piercing portion 3 is fixedly connected to the storage cover, and the storage cover is arranged as an elastic material layer, such as a material that can be elastically deformed, such as silicone or soft plastic.

[0055] A protrusion is provided on the top wall of the bottle cap body 2 at a position corresponding to the puncture portion 3 , and the distance from the protrusion to the puncture portion 3 is less than the height of the anti-theft ring 4 .

[0056] When in use, the anti-theft ring 4 is removed, the bottle cap body 2 moves toward the bottle mouth 6 (i.e., moves downward), the piercing portion 3 is squeezed by the protrusion, the storage cover is elastically deformed by the force and moves downward, and the piercing portion 3 is simultaneously pushed downward, so that the piercing portion 3 pierces the sealing layer 11 to open the storage bin 1, so that the storage bin 1 is connected with the bottle body.

[0057] Preferably, the material storage cap separates the material storage barrel into a material storage bin 1 and a mounting portion, and the mounting portion is adapted to the piston portion 21 . When the puncturing portion 3 punctures the material storage bin 1 , the bottle cap body 2 is tightly connected to the material storage bin 1 as a whole through the piston portion 21 .

[0058] Embodiment 4:

[0059] The main difference between it and Example 1 is:

[0060] In this embodiment, the storage bin 1 is formed with a sealed inner cavity by a storage cylinder and two layers of sealing films 1. The piercing portion 3 can be placed obliquely in the sealed inner cavity; when the anti-theft ring 4 is removed and the bottle cap body 2 moves downward, the piston portion 21 can squeeze the piercing portion 3 and then pierce the storage bin 1.

[0061] Of course, the piercing portion 3 can also be fixed to the inner wall of the storage barrel by a cantilever. There are at least two cantilevers, and the cantilevers can be deformed. A protrusion corresponding to the piercing portion 3 is provided on the inner top wall of the bottle cap body 2.
