Abstract
Description
Technical Field
[0001] This utility model relates to the field of aseptic storage container technology, specifically to an aseptic storage container with a long-lasting sealing structure. Background Technology
[0002] Sterile storage containers are specialized bottles used for storing and transporting biological products. These bottles are manufactured using strict aseptic processes to ensure that the biological fluids inside remain uncontaminated. Sterile storage containers are typically made of transparent polycarbonate or polypropylene, allowing users to clearly see the contents. The caps and seals are also manufactured using aseptic processes to ensure no bacterial contamination occurs during storage and transportation. These bottles are widely used in biological laboratories, hospitals, pharmacies, and other fields as effective and reliable storage devices for biological products.
[0003] Most existing aseptic storage containers use threaded caps with a single sealing ring. However, this single sealing ring is prone to deformation after repeated opening and closing, leading to seal failure. Furthermore, the sealing ring is prone to displacement when the threaded cap rotates and engages with the bottle neck, affecting the sealing effect. Utility Model Content
[0004] The purpose of this invention is to provide a sterile storage container with a long-lasting sealing structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sterile storage container with a long-lasting sealing structure, comprising a bottle body, a bottle cap, and a bottle mouth, wherein the bottle mouth is disposed at the top of the bottle body, and the bottle cap is threadedly connected to the outside of the bottle mouth. The bottle cap comprises a cap body, a fixing component, a first rectangular thread, a main sealing ring, a first secondary sealing ring, and a second secondary sealing ring. The fixing component is disposed in the middle of the cap body, the first rectangular thread is disposed around the inner wall of the cap body, the main sealing ring is disposed at the top inside the cap body, the first secondary sealing ring is disposed on the outside of the bottom end of the main sealing ring, and the second secondary sealing ring is disposed on the inside of the bottom end of the main sealing ring.
[0006] Preferably, the outer side of the first rectangular thread is covered with silicone.
[0007] Preferably, a second rectangular thread is provided on the outer side of the bottle opening, and the outer side of the second rectangular thread is covered with the same silicone as the outer side of the first rectangular thread.
[0008] Preferably, the fixing component includes a tray, a threaded rod, and a threaded cover. The top end of the tray contacts the bottom end of the main sealing ring, the middle part of the top end of the tray is connected to one end of the threaded rod, and the other end of the threaded rod passes through the top end of the main sealing ring and the cover body, and is threadedly fitted with the threaded cover.
[0009] Preferably, a layer of silicone is connected to the bottom end of the threaded cap.
[0010] Preferably, there is a gap between the first and second sealing rings, and the bottle mouth is inserted into the gap and contacts the first and second sealing rings.
[0011] Compared with the prior art, the beneficial effects of this utility model are: Both the outer side of the bottle opening and the inner side of the bottle cap are equipped with rectangular threads coated with silicone. The rectangular threads have high transmission performance, and the silicone coating can reduce thread wear and fill the gaps between the rectangular thread connections, thereby enhancing the overall sealing performance. The bottle cap also has a combination sealing ring inside. The multi-stage sealing system ensures that the failure of a single sealing point will not cause the entire system to fail, achieving a long-lasting sealing effect. The main sealing ring seals the bottle opening axially, while two sets of secondary sealing rings seal the bottle opening radially. This prevents external substances from contaminating the contents of the bottle and also prevents the contents from leaking out. A fixing component is also provided to fix the combination sealing ring, preventing the sealing ring from shifting due to rotational friction when the bottle cap is connected to the bottle opening.

Detailed Implementation
[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0019] Please see Figures 1-5 This utility model provides a sterile storage container with a long-lasting sealing structure, including a bottle body 1, a bottle cap 2, and a bottle mouth 3. The bottle mouth 3 is integrally connected to the top of the bottle body 1, and the bottle cap 2 is threadedly connected to the outside of the bottle mouth 3. Please refer to [link / reference]. Figures 1-5In this invention, the bottle cap 2 includes a cap body 21, a fixing component 22, a first rectangular thread 23, a main sealing ring 24, a first secondary sealing ring 25, and a second secondary sealing ring 26. The fixing component 22 is disposed in the middle of the cap body 21 and includes a tray 221, a threaded rod 222, and a threaded cap 223. The top end of the tray 221 contacts the bottom end of the main sealing ring 24, and the middle of the top end of the tray 221 is connected to one end of the threaded rod 222. The other end of the threaded rod 222 passes through the main sealing ring 24 and the top end of the cap body 21, and is threadedly fitted with the threaded cap 223 to fix the main sealing ring 24 and prevent the main sealing ring 24 from shifting when the bottle cap 2 rotates on the bottle mouth 3. A layer of silicone is connected to the bottom end of the threaded cap 223 to seal the gap created by the threaded rod 222 passing through the cap body 21. The first rectangular thread 24 is integrally formed around the inner wall of the cap body 21, and the outer side of the first rectangular thread 23 is covered with silicone to protect the thread and reduce friction between the threads. The main sealing ring 24 is fitted inside the top of the cap 21. The first auxiliary sealing ring 25 is integrally connected to the outer side of the bottom end of the main sealing ring 24, and the second auxiliary sealing ring 26 is integrally connected to the inner side of the bottom end of the main sealing ring 24. There is a gap between the two sets of auxiliary sealing rings, and the bottle mouth 3 is embedded in the gap and in contact with the two sets of auxiliary sealing rings. Therefore, the main sealing ring 24 is tightly attached to the top of the bottle mouth 3, which plays a role in axial sealing. The first auxiliary sealing ring 25 is tightly attached to the outer wall of the bottle mouth 3, and the second auxiliary sealing ring 26 is tightly attached to the inner wall of the bottle mouth 3, which plays a role in radial sealing. This can prevent external impurities from contaminating the contents of the bottle and also prevent the contents of the bottle from being lost, which greatly increases the sealing performance of the sterile container. The outer side of the bottle mouth 3 is integrally formed with a second rectangular thread 31. The outer side of the second rectangular thread 31 is covered with the same silicone as the outer side of the first rectangular thread 23. When the two are rotated and fitted, the silicone can reduce the wear between the two and fill the gap between the threaded connections, which further increases the overall sealing performance of the sterile container.
[0020] Specifically, first, place the main sealing ring 24 inside the top of the cap body 21. Then, pass the smooth end of the threaded rod 222 through the main sealing ring 24 and the top of the cap body 21, so that the tray 221 connected to the other end of the threaded rod 222 is in close contact with the main sealing ring 24. Next, install the threaded cap 223 onto the smooth end of the threaded rod 222 and tighten the threaded cap 223 so that the silicone sheet at the bottom of the threaded cap 223 is in close contact with the top of the cap body 21. After assembling the cap 2, put the items to be stored into the bottle body 1 and tighten the cap 2 to complete the sealing of the items. The operation is simple, and the multiple sealing devices greatly enhance the overall sealing performance of the sterile container.
