Description

Technical Field

[0001] This invention belongs to the field of culture flask technology, specifically a culture flask that facilitates secondary liquid addition. Background Technology

[0002] Currently, when culturing cells in the laboratory, cells and fresh culture medium are placed in culture flasks to allow the cells to grow. These culture flasks are usually for single use only. During cell culture, the cells gradually absorb the culture medium components during their metabolism. Therefore, users must regularly add culture medium to the culture flasks to ensure normal cell growth.

[0003] In existing culture flasks, the process of adding culture medium mostly involves unscrewing the threaded cap on one side of the flask and then adding the culture medium a second time. This method may cause external factors to affect the internal structure. Therefore, silicone seals are used for injection. However, existing silicone seals are prone to aging after being idle for a long time. Since silicone seals are generally fixed directly to the culture flask with glue, they are difficult to disassemble and replace. This may lead to contamination and other issues affecting the experimental structure during secondary injection. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a culture flask that facilitates secondary liquid addition. It solves the problem that existing silicone seals are prone to aging after being idle for a long time. Since silicone seals are generally fixed directly to the culture flask with glue, they are difficult to disassemble and replace, which may lead to contamination and other issues affecting the experimental structure during secondary injection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a culture flask for easy secondary liquid addition, comprising a flask body, a light-transmitting plate at the top of the flask body, a plugging hole at the top of the light-transmitting plate, a bottom ring at the top of the light-transmitting plate corresponding to the plugging hole, an mounting ring fixedly connected to the surface of the bottom ring, a plurality of silicone extrusion blocks fixedly connected in an array on the inner wall of the mounting ring, silicone sealing blocks being disposed between the plurality of silicone extrusion blocks, a silicone plugging block fixedly connected to the bottom of the silicone sealing block, the silicone plugging block being snapped into the inner wall of the plugging hole, and a silicone fixing block fixedly connected to the bottom of the silicone plugging block passing through the plugging hole.

[0006] As a further embodiment of this utility model: a fixing ring is fixedly connected to one side surface of the mounting ring, a connecting ring is snapped into the fixing ring, and a protective rope is fixedly connected to one side of the connecting ring.

[0007] As a further embodiment of this utility model: one end of the protective rope is fixedly connected to a fixing seat, and the bottom of the fixing seat is fixedly connected to the top of the light-receiving plate.

[0008] As a further embodiment of this utility model: a threaded tube is fixedly connected to one side of the light-receiving plate, and a threaded cap is connected to the external thread of the threaded tube through the thread.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This culture flask, which facilitates secondary liquid addition, features a silicone sealing block, plug, and mounting ring. Due to prolonged periods of inactivity, the silicone sealing block, plug, and fixing block are prone to aging and deformation, affecting the flask's seal. In such cases, new silicone sealing blocks, plugs, and fixing blocks can be replaced. The new blocks are placed on top of the mounting ring, passing through the bottom ring until the sealing block is inserted into the mounting ring. The silicone compression block on the inner wall of the mounting ring continuously presses against the sealing block, securing it firmly. This facilitates replacement of the silicone sealing block, plug, and fixing block, preventing them from aging due to prolonged inactivity and affecting experimental results.

[0011] 2. This culture flask, which facilitates secondary liquid addition, is equipped with a fixing base, a protective rope, and a connecting ring. The fixing base secures the protective rope to the light-exposing plate, while the connecting ring engages with the fixing ring. This design uses the protective rope to protect the mounting ring, preventing it from falling off and being lost. Attached Figure Description

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0016] like Figure 1-2As shown, this utility model provides a technical solution: a culture bottle for easy secondary liquid addition, comprising a bottle body 1, a light-transmitting plate 2 at the top of the bottle body 1, a plugging hole 3 at the top of the light-transmitting plate 2, a bottom ring 5 corresponding to the top of the plugging hole 3, an mounting ring 4 fixedly connected to the surface of the bottom ring 5, and a plurality of silicone extrusion blocks 6 fixedly connected in an array on the inner wall of the mounting ring 4, with silicone sealing blocks 7 arranged between the silicone extrusion blocks 6, the silicone sealing blocks 7 being in contact with the silicone extrusion blocks 6 on all sides, and the cross-sectional area of ​​the silicone sealing blocks 7 being larger than the cross-sectional area of ​​the plugging hole 3. Through the arrangement of the silicone extrusion blocks 6, the silicone extrusion blocks 6 are evenly distributed on the inner wall of the silicone mounting ring 4, and the silicone sealing blocks 7 are compressed and fixed by the multiple silicone extrusion blocks 6 and the silicone sealing blocks 7.

[0017] A silicone sealing block 7 is fixedly connected to a silicone plug 8 at its bottom. The silicone plug 8 is snapped into the inner wall of the plug hole 3. A silicone fixing block 9 is fixedly connected to the bottom of the silicone plug 8 through the plug hole 3. The cross-sectional area of ​​the top of the silicone fixing block 9 is larger than the cross-sectional area of ​​the plug hole 3. In this embodiment, the silicone sealing block 7 and the silicone plug 8 are preferably cylindrical, and the silicone fixing block 9 is a frustum-shaped block with a gradually decreasing bottom diameter, which matches the circular plug hole 3 for easy installation.

[0018] A fixing ring 10 is fixedly connected to one side of the mounting ring 4. A connecting ring 11 is snapped into the fixing ring 10. A protective rope 12 is fixedly connected to one side of the connecting ring 11. A fixing seat 13 is fixedly connected to one end of the protective rope 12. The bottom of the fixing seat 13 is fixedly connected to the top of the light-receiving plate 2. By setting the fixing seat 13, the protective rope 12 is used to limit the silicone sealing block 7 through the connecting ring 11 and the fixing ring 10 to prevent the silicone sealing block 7 from falling accidentally. The fixing seat 13 can fix the protective rope 12 to the top of the light-receiving plate 2 to prevent the protective rope 12 from falling.

[0019] A threaded tube 14 is fixedly connected to one side of the bottle body 1. A threaded cap 15 is threadedly connected to the external thread of the threaded tube 14. The threaded cap 15 is provided with a vent or a breathable membrane. By setting the threaded tube 14 and the threaded cap 15, different threaded caps 15 can be rotated and screwed into the threaded tube 14. By changing the threaded caps 15 with different ventilation levels, the gas balance required for cell growth can be maintained.

[0020] The working principle of this utility model is as follows: In use, the cells to be cultured are first placed into the bottle 1. When it is necessary to inject culture medium into the bottle 1, the syringe injects the culture medium into the bottle 1 through the silicone sealing block 7. At this time, the silicone sealing block 7 can be replaced. Since the silicone fixing block 9, silicone plug 8, and silicone sealing block 7 are prone to aging and deformation if left idle for a long time, the deformed silicone plug 8 and silicone fixing block 9 are pulled out from the plug hole 3, thereby replacing the silicone fixing block 9, silicone plug 8, and silicone sealing block 7. Pull out the new silicone fixing block 9, silicone plug 8, and silicone sealing block 7 from the inside of the mounting ring 4 and insert them into the mounting ring 4. The silicone sealing block 7 is fixed by the silicone extrusion block 6, which makes it easy to replace the silicone sealing block 7. Insert the new silicone plug 8 and silicone fixing block 9 into the plug hole 3. At this time, the silicone fixing block 9 will slide on the inner wall of the plug hole 3 until the silicone fixing block 9 is inserted into the bottle body 1. At this time, the silicone fixing block 9 will engage with the plug hole 3, so that the inside of the bottle body 1 is in a relatively sealed state. The transparent bottle body 1 allows the operator to directly observe the cell culture status.
