Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a storage bottle cap assembly and a bottle. Background Technology

[0002] The preparation of mixed solutions typically involves dissolving the solute in a solvent. However, because the solute easily precipitates and some components are prone to hydrolysis in the solvent, the shelf life of mixed solutions is shorter than that of solutions stored separately from the solute. To improve the shelf life of mixed solutions, numerous bottles capable of solid-liquid separation have been invented in the prior art, thereby extending the shelf life of the mixed solutions.

[0003] For example, a sealed bottle cap assembly and its bottle are disclosed in the existing patent publication number CN222180441U. The bottle cap assembly includes a storage bin and a bottle cap body. The bottle cap body is used to fit over the bottle mouth. The storage bin has an inner cavity and an opening communicating with the inner cavity. The storage bin can extend into the bottle mouth. The opening has a sealing layer to seal the material in the inner cavity of the storage bin. The storage bin has a puncture part. When the bottle cap body is rotated and moves toward the bottle mouth, the bottle cap body applies pressure to the puncture part to puncture the storage bin, so that the storage bin is connected to the bottle body.

[0004] However, when using the aforementioned sealing cap assembly and its bottle, the tamper-evident ring needs to be pulled off, and then the cap body needs to be rotated towards the bottle opening. This causes the cap body to apply pressure to the puncture point to puncture the storage compartment, thus connecting the storage compartment to the bottle body. During the rotation of the cap body towards the bottle opening, friction and pressure will occur between the cap body and the bottle opening. If the user rotates it improperly or the pressure between the cap body and the bottle opening is too great, the threaded seal between the cap body and the bottle opening may weaken or fail, causing the liquid inside the bottle to leak from the tiny gap between the cap body and the bottle opening.

[0005] In summary, the existing sealed bottle cap assembly, which uses rotational pressure to connect the storage compartment to the bottle body, is prone to weakening or failure of the threaded seal between the bottle cap body and the bottle mouth, resulting in leakage of liquid from the tiny gap between the bottle cap body and the bottle mouth. Summary of the Invention

[0006] One of the objectives of this utility model is to provide a storage bottle cap assembly and a bottle, which aims to solve the technical problem that existing bottle cap assemblies use a rotating pressure method to connect the storage bin to the bottle body, which easily leads to weakening or failure of the threaded seal between the bottle cap body and the bottle mouth, resulting in leakage of liquid from the tiny gap between the bottle cap body and the bottle mouth.

[0007] To achieve the above objectives, this utility model provides a storage bottle cap assembly, including a bottle cap body, a storage bin, and a puncture part. The bottle cap body is fitted onto the bottle mouth. The first end of the storage bin is limited by the bottle mouth and located inside the bottle cap body. The second end of the storage bin is sealed and can extend into the bottle mouth. The puncture part is located inside the storage bin. An installation port communicating with the inner cavity of the storage bin is provided on the end face of the bottle cap body facing away from the bottle mouth. A pressing member for sealing the cap itself is provided on the installation port. The pressing member can be elastically deformed. The end of the puncture part near the pressing member is a contact part. Under the action of external pressing force, the pressing member forces the contact part to drive the puncture part to move down and puncture or open the sealed end of the storage bin, so that the storage bin is connected to the bottle body.

[0008] As a preferred embodiment of this utility model, the end of the puncture portion facing away from the contact portion is configured as a sealing portion for sealing the second end port of the storage bin.

[0009] As a preferred embodiment of this utility model, the sealing part includes a sealing ring and a base. The base is connected and fixed to the puncture part. The sealing ring is fixed on the peripheral side wall of the base and is sealed and fitted to the inner wall of the storage bin.

[0010] As a preferred embodiment of this utility model, a first sealing groove adapted to the sealing ring is provided on the peripheral side wall of the base.

[0011] As a preferred embodiment of the present invention, a second sealing groove is provided in the first sealing groove along its circumference, and an annular sealing protrusion adapted to the second sealing groove is provided on the inner wall of the sealing ring.

[0012] As a preferred technical solution of this utility model, the storage silo is a glass storage silo, a plastic storage silo, a ceramic storage silo, or a metal storage silo.

[0013] As a preferred embodiment of this utility model, the inner diameter of the second end port of the storage bin is smaller than the inner diameter of the first end port of the storage bin; a cantilever is provided on the puncture part, the cantilever extends radially within the storage bin, and the length of the cantilever is greater than the inner diameter of the second end port of the storage bin.

[0014] As a preferred embodiment of this utility model, the pressing component includes an installation part and a pressing part that are connected to each other. The installation part is connected and fixed to the installation port. The pressing part has an arched structure and is coaxially arranged with the contact part.

[0015] As a preferred embodiment of this utility model, a sealing element is provided between the upper surface of the first end port of the storage bin and the bottle cap body.

[0016] On the other hand, the present invention provides a bottle, including a bottle body and the aforementioned bottle cap assembly, wherein the bottle cap assembly is assembled on the bottle body having a bottle mouth.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In use, the second end of the storage compartment is inserted into the bottle opening, while the first end of the storage compartment is confined outside the bottle opening. The bottle cap body is then fitted onto the bottle opening. Because the second end of the storage compartment is sealed, when it is necessary to connect the storage compartment to the bottle body, the pressing element on the bottle cap body is pressed. Under the external pressing force, the pressing element forces the contact part to move downward, piercing or opening the sealed end of the storage compartment, thereby connecting the storage compartment to the bottle body. In summary, this invention uses a pressing method to force the piercing part to move downward, piercing or opening the sealed end of the storage compartment, thus connecting the storage compartment to the bottle body. This overcomes the defect of existing bottle cap assemblies that use rotational pressure to connect the storage compartment to the bottle body, which easily leads to weakening or failure of the threaded seal between the bottle cap body and the bottle opening, resulting in leakage of liquid from the tiny gap between the bottle cap body and the bottle opening.

[0033] Example 1

[0034] Please refer to Figure 1 - Figure 7This utility model provides a bottle cap assembly for storage, including a bottle cap body 1, a storage bin 2, and a puncture part 3. The bottle cap body 1 is fitted onto the bottle mouth and is threadedly connected to the bottle mouth. The first end of the storage bin 2 is located inside the bottle cap body 1, and the outer edge of the first end of the storage bin 2 has an annular limiting part 22, which can be supported by the top port of the bottle mouth, allowing the first end of the storage bin 2 to be limited outside the bottle mouth. Furthermore, the second end of the storage bin 2 is sealed and can extend into the bottle mouth.

[0035] The puncture part 3 is located inside the storage bin 2 and extends axially along the storage bin 2. An installation port 10 communicating with the inner cavity of the storage bin 2 is provided on the end face of the bottle cap body 1 facing away from the bottle opening. A pressing member 101 for sealing the cap is provided on the installation port 10; naturally, the pressing member 101 can elastically deform. A contact part 30 is provided at one end of the puncture part 3 near the pressing member 101.

[0036] Under the external pressing force, the pressing member 101 forces the contact part 30 to drive the piercing part 3 to move down and pierce or open the sealing end of the storage bin 2, thereby making the storage bin 2 connected to the bottle body.

[0037] When using the storage cap assembly and bottle of this utility model, the second end of the storage bin 2 is inserted into the bottle mouth, and the end of the first end of the storage bin 2 is limited outside the bottle mouth by the bottle mouth. The bottle cap body 1 is fitted onto the bottle mouth of the bottle body. Because the port of the second end of the storage bin 2 is sealed, when it is necessary to connect the storage bin 2 with the bottle body, the pressing member 101 on the bottle cap body 1 is pressed. Then, under the external pressing force, the pressing member 101 forces the contact part 30 to drive the piercing part 3 to move down to pierce or open the sealed end of the storage bin 2, thereby connecting the storage bin 2 with the bottle body. In summary, this utility model uses a pressing method to force the puncture part 3 to move downward, puncture or open the sealing end of the storage bin 2, thereby connecting the storage bin 2 with the bottle body. This overcomes the defect of existing bottle cap assemblies that connect the storage bin 2 with the bottle body by rotating and applying pressure, which easily leads to weakening or failure of the thread seal between the bottle cap body 1 and the bottle mouth, resulting in leakage of liquid from the tiny gap between the bottle cap body 1 and the bottle mouth.

[0038] In one embodiment, reference is made to Figure 3 The outer ring of the annular limiting part 22 can be connected to the bottle cap body 1 as a whole; of course, in other embodiments, the annular limiting part 22 can also be not connected to the bottle cap body 1, that is, the bottle cap body 1 and the storage bin 2 are designed separately, which is not limited here.

[0039] In one embodiment, reference is made to Figure 3One end of the puncture portion 3 facing away from the contact portion 30 is configured as a sealing portion 31, which seals the second end port of the storage bin 2. When the pressing member 101 applies external pressure, it forces the contact portion 30 to drive the puncture portion 3 downward, causing the sealing portion 31 on the puncture portion 3 to move downward and open the sealed end of the storage bin 2, thereby connecting the storage bin 2 with the bottle body. This solves the defect that the storage bin 2 is difficult to puncture after being sterilized by irradiation, and facilitates the connection between the storage bin 2 and the bottle body.

[0040] In one embodiment, reference is made to Figure 3 and Figure 5 The sealing part 31 includes a sealing ring 310 and a base 311. The base 311 is integrally formed with the puncture part 3, so that the base 311 and the puncture part 3 are connected and fixed. The sealing ring 310 is fixed on the peripheral sidewall of the base 311, and the sealing ring 310 is sealed and fitted with the inner wall of the storage bin 2, thereby achieving port sealing at the second end of the storage bin 2. Specifically, a first sealing groove 312 adapted to the sealing ring 310 is provided on the peripheral sidewall of the base 311. The first sealing groove 312 facilitates the installation of the sealing ring 310. In addition, a second sealing groove 313 is formed in the first sealing groove 312 along its own circumference, and an annular sealing protrusion 314 adapted to the second sealing groove 313 is provided on the inner wall of the sealing ring 310. The sealing performance of the sealing part 31 can be further improved by connecting the annular sealing protrusion 314 with the second sealing groove 313.

[0041] In one embodiment, the storage bin 2 is a plastic storage bin 2; of course, in other embodiments, the storage bin 2 may also be a glass storage bin 2, a ceramic storage bin 2, or a metal storage bin 2, and is not limited here.

[0042] In one embodiment, reference is made to Figure 3 and Figure 4 The inner diameter of the second end port of the storage silo 2 is smaller than the inner diameter of the first end port of the storage silo 2. Specifically, the first end of the storage silo 2 is formed by the first sleeve 20, and the second end of the storage silo 2 is formed by the second sleeve 21. The inner diameter of the second sleeve 21 is smaller than the inner diameter of the first sleeve 20. The lower end of the first sleeve 20 is connected to and communicates with the upper end of the second sleeve 21. The lower end of the second sleeve 21 is sealed by the aforementioned sealing part 31. The upper end of the first sleeve 20 is the feed inlet, through which materials can enter the storage silo 2.

[0043] In one embodiment, reference is made to Figure 3 and Figure 4The puncture part 3 is provided with a cantilever 4, which extends radially within the storage bin 2. The length of the cantilever 4 is greater than the inner diameter of the second end port of the storage bin 2. In other words, the length of the cantilever 4 is greater than the inner diameter of the second sleeve 21, and the length of the cantilever 4 is less than the inner diameter of the first sleeve 20. The two ends of the cantilever 4 do not contact the inner wall of the first sleeve 20. This reduces the friction between the cantilever 4 and the first sleeve 20 during the downward movement of the puncture part 3, ensuring smooth downward movement of the puncture part 3. When the cantilever 4 moves down with the puncture part 3 to the connection position of the first sleeve 20 and the second sleeve 21, the cantilever 4 is limited by the connection between the first sleeve 20 and the second sleeve 21. At this time, the sealing part 31 moves down into the bottle body, and the puncture part 3 stops moving down, so that the storage bin 2 can be connected to the bottle body. In addition, since the cantilever 4 is limited inside the first sleeve 20 and is fixedly connected to the puncture part 3, the user can shake the bottle to make the sealing part 31 shake inside the bottle body, which can stir the solution inside the bottle body and improve the mixing effect of solute and solvent.

[0044] In one embodiment, the pressing member 101 is made of silicone material, but is not limited to silicone material. Specifically, refer to... Figure 1 and Figure 3 The pressing component 101 includes a mounting portion 1011 and a pressing portion 1012, which are integrally formed. The mounting portion 1011 is connected and fixed to the mounting opening 10, and the pressing portion 1012 is coaxially arranged with the contact portion 30. The pressing portion 1012 has an arched structure, which facilitates the restoration of its elastic deformation capacity. Therefore, by pressing the pressing portion 1012, the user can drive the contact portion 30 to move the puncture portion 3 downwards.

[0045] In addition, the area of ​​the contact portion 30 can be increased to increase the contact area between the contact portion 30 and the pressing portion 1012, thereby reducing the effort required when the user presses the pressing portion 1012.

[0046] In one embodiment, reference is made to Figure 3 A sealing element 5 is provided between the upper surface of the first end port of the storage hopper 2 and the bottle cap body 1. The sealing element 5 can prevent external air from entering the storage hopper 2 and contacting the material inside the storage hopper 2, thereby preventing the material stored in the storage hopper 2 from getting damp and extending the storage time of the material in the storage hopper 2.

[0047] In one embodiment, a removable protective cap 7 is also provided on the bottle cap body 1. The protective cap 7 is used to prevent external pressure from accidentally activating the aforementioned pressing member 101. Specifically, as shown... Figure 7 As shown, in this embodiment, the protective cap 7 is detachably fitted onto the bottle cap body 1, so that the pressing member 101 is located within the receiving cavity 70 formed between the upper surface of the bottle cap body 1 and the protective cap 7; in other embodiments, such as Figure 8 As shown, the protective cap 7 can also be detachably mounted on the upper surface of the bottle cap body 1, and the protective cap 7 covers the aforementioned pressing member 101. Therefore, it can be seen that by reasonably changing the position of the protective cap 7 on the bottle cap body 1, it should also fall within the protection scope of this utility model.

[0048] This utility model also provides a bottle, including a bottle body and the aforementioned bottle cap assembly, the bottle cap assembly being assembled onto the bottle body having a bottle opening. Because the bottle in this embodiment utilizes the aforementioned bottle cap assembly, the bottle can achieve separation of the material in the storage bin 2 from the solution inside the bottle body, thus extending the product's shelf life.

[0049] The bottle in this embodiment can be used for culture media, that is, the bottle in this embodiment can also be used as a culture media device. Traditional liquid culture media have high storage requirements, need to be stored and transported in cold storage, have a short shelf life, and are prone to precipitation. Using the above-mentioned bottle as a culture medium can solve the above problems. It is convenient and quick to use. Not only does it not require cold storage and transportation, but it can also be stored in the dark. Moreover, it is not easy to produce precipitation. In addition, the storage bin 2 has good sealing performance, which can prevent the materials in the storage bin 2 from being affected by the external environment.

[0050] Of course, in other embodiments, the bottle of this utility model can also be applied to the fields of pharmaceuticals, food, beverages, cosmetics, health products, etc., and is not limited here.

[0051] Example 2

[0052] The difference between this embodiment and Embodiment 1 is that the sealing structure of the second end of the storage bin 2 is different.

[0053] Reference Figure 8 The second end of the storage bin 2 is sealed by a sealing layer 6, which can be tin foil. The lower end of the piercing part 3 is configured as a piercing end 32. When it is necessary to connect the storage bin 2 with the bottle body, the pressing member 101 on the bottle cap body 1 is pressed. Under the external pressing force, the pressing member 101 forces the contact part 30 to drive the piercing part 3 downward, thereby causing the piercing end 32 on the piercing part 3 to pierce the sealing layer 6, so that the storage bin 2 is connected with the bottle body.

[0054] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
