Description

Technical Field

[0001] This utility model relates to the field of cell culture flask technology, and in particular to an insertable, anti-tipping, stackable cell culture flask. Background Technology

[0002] In vitro culture of cells and tissues has become an indispensable part of life research and practice. Cell culture flasks are mainly used for small-scale in vitro culture of animal cells or tissues. Commercial cell culture flasks are mainly made of glass and plastic, and the bottom of the flasks can be square, rectangular, triangular, trapezoidal, etc. In the field of cell culture, cell culture flasks are commonly used experimental instruments.

[0003] For example, a Chinese patent discloses a cell culture flask, patent number: CN215628023U. Through the cooperation of the Г-shaped guide groove and the Г-shaped guide rail, the cover can be flexibly slid into the opening of the flask while having good sealing performance. The first sealing strip is set to increase the overall sealing effect of the cell culture flask. When it is necessary to put in or take out cultured cells, it is not only possible to operate through the neck, but also more conveniently to operate by sliding out the cover. The operation is convenient.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: the culture flasks in the above device lack a stacking mechanism. When multiple culture flasks need to be moved or stacked in the incubator, they are simply piled up together. They are prone to tipping over due to shaking, collision or imbalance, which leads to cell death and waste of experimental materials. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an insertable anti-tipping stackable cell culture flask, solving the technical problem that the above-mentioned devices lack a stacking mechanism for the culture flasks. When multiple culture flasks need to be moved or stacked in an incubator, they are simply piled together, which is prone to tipping over due to shaking, collision, or imbalance, resulting in cell death and waste of experimental materials.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An insertable, anti-tipping, stackable cell culture flask includes a culture flask body. A connecting seat is fixedly connected to the upper end of the culture flask body. Two pressing rods are slidably connected inside the connecting seat. The two pressing rods are compatible with each other. A locking rod is fixedly connected inside each of the two pressing rods. A ring is fixedly connected inside each of the two connecting seats. A return spring is sleeved at the far end of each of the two rings. A stacking mechanism is fixedly connected to the lower end of the culture flask body. The stacking mechanism includes a locking base, which is fixedly connected to the lower end of the culture flask body.

[0010] Preferably, the outer surface of the snap-fit ​​base is fitted with a rubber pad, and the inside of the connector has two circular grooves.

[0011] Preferably, the lower end of the snap-fit ​​base is fixedly connected to two positioning posts.

[0012] Preferably, the upper end of the culture flask body is fixedly connected to a bottle mouth, and a bottle cap is threadedly connected to the outer surface of the bottle mouth.

[0013] Preferably, the outer surface of the bottle cap is fixedly connected with anti-slip texture, and the inside of the culture bottle body is provided with a storage groove.

[0014] Preferably, the bottle cap and the storage slot are on the same vertical line, and the anti-slip texture is compatible with the storage slot.

[0015] (III) Beneficial Effects

[0016] 1. When multiple culture flasks need to be moved or stacked in an incubator, align the lower end of one culture flask with the lower end of another, and press the two pressing rods towards the center. At this time, align the locking base with the upper end of the connector, release the two pressing rods, and the two pressing rods will slide back to their original position under the action of the return spring. The two pressing rods will then drive the locking rod to slide and lock into the locking base, thus realizing the stacking of the two culture flasks. This effectively prevents the culture flasks from tipping over during stacking, which helps to improve the stability of the culture flask stacking operation and reduces the risk of culture medium leakage and cell sample damage caused by tipping over. When one of the culture flasks needs to be retrieved, simply press the pressing rod again to release the locking rod and the locking base, and the culture flask can be easily removed. The operation is relatively simple and convenient, which helps to improve the work efficiency of the experimenters.

[0017] 2. Align the snap-fit ​​base with the upper end of the connector. At this time, the cap will extend vertically into the storage groove inside the culture flask. The storage groove and the anti-slip texture on the outside of the cap are matched. When the cap is inserted into the storage groove, it is not easy for the cap to be bumped or rubbed and rotated or loosened, thereby reducing the risk of liquid leakage and contamination, which helps to ensure the purity and accuracy of cell culture.

[0024] This application provides an insertable, anti-tipping stackable cell culture flask, effectively solving the problem of the lack of a stacking mechanism in the aforementioned devices. When multiple culture flasks need to be moved or stacked in an incubator, they are simply piled together, easily tipping over due to shaking, collision, or imbalance, leading to cell death and waste of experimental materials. When multiple culture flasks need to be moved or stacked in an incubator, one culture flask is aligned with the lower end of another, and the two pressing rods are pressed towards the center. At this time, the snap-fit ​​base is aligned with the connecting... At the upper end of the base, releasing the two pressing rods causes the two pressing rods to slide back to their original position under the force of the return spring. The two pressing rods then drive the locking rod to slide and lock into the locking base, enabling the stacking of two culture flasks. This effectively prevents the culture flasks from tipping over during stacking, improving the stability of the stacking operation and reducing the risk of culture medium leakage and cell sample damage caused by tipping over. When one of the culture flasks needs to be retrieved, simply press the pressing rod again to release the locking rod and the locking base, and the culture flask can be easily removed. The operation is relatively simple and convenient, which helps improve the work efficiency of laboratory personnel.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the above-mentioned device lacks a stacking mechanism for culture flasks. When multiple culture flasks need to be moved or stacked in an incubator, they are simply piled together, which easily leads to tipping due to shaking, collision, or imbalance, resulting in cell death and waste of experimental materials. The overall idea is as follows: An insertable anti-tipping stackable cell culture flask includes a culture flask body 11, a connecting seat 12 fixedly connected to the upper end of the culture flask body 11, and two sliding connections inside the connecting seat 12. Two pressing rods 13 are matched and each pressing rod 13 has a locking rod 14 fixedly connected inside. Two connecting seats 12 each have a ring 15 fixedly connected inside. A return spring 16 is sleeved on the opposite end of each ring 15. A stacking mechanism is fixedly connected to the lower end of the culture flask body 11. The stacking mechanism includes a locking base 17, which is fixedly connected to the lower end of the culture flask body 11. When multiple culture flask bodies 11 need to be moved or stacked in an incubator (the incubator can be adjusted and set), the mechanism is used for this purpose. At a suitable temperature, align one culture flask body 11 with the lower end of the other culture flask body 11. Then, press the two pressing rods 13 towards the center (near one end of the ring 15). (The two pressing rods 13 are compatible; when they slide simultaneously, one rod will slide into the other, saving space.) Align the snap-fit ​​base 17 with the upper end of the connecting seat 12. Release the two pressing rods 13. Under the force of the return spring 16, the two pressing rods 13 will slide back to their original position. The locking lever 14 slides and engages with the locking base 17 to allow two culture flask bodies 11 to be stacked, effectively preventing the culture flasks from tipping over during stacking. This improves the stability of the culture flask stacking operation and reduces the risk of culture medium leakage and cell sample damage caused by tipping over. When one of the culture flask bodies 11 needs to be retrieved, simply press the pressing lever 13 again to release the engagement between the locking lever 14 and the locking base 17, and the culture flask body 11 can be easily removed. The operation is relatively simple and convenient, which helps to improve the work efficiency of the experimental personnel.

[0027] A rubber pad 18 is fitted onto the outer surface of the snap-fit ​​base 17. Two circular grooves 19 are opened inside the connecting seat 12. Two positioning posts 21 are fixedly connected to the lower end of the snap-fit ​​base 17. Both positioning posts 21 are adapted to the two circular grooves 19. A bottle mouth 22 is fixedly connected to the upper end of the culture bottle body 11. A bottle cap 23 is threaded onto the outer surface of the bottle mouth 22. Anti-slip texture 24 is fixedly connected to the outer surface of the bottle cap 23. In the experimental environment, cells and the culture medium required for their growth are put into the culture bottle body 11 to provide a suitable environment for cell growth. The culture bottle body 11 is made of transparent material, and the cell growth stage can be directly observed through the culture bottle body 11. During use, the culture bottle body 11 is opened and closed by twisting the bottle cap 23. When holding and twisting the bottle cap 23, the anti-slip texture 24 connected to its surface provides anti-slip properties.

[0028] The culture flask body 11 has a storage groove 25 inside. The bottle cap 23 and the storage groove 25 are on the same vertical line. The anti-slip texture 24 is compatible with the storage groove 25. The rubber pad 18 on the outer sleeve of the snap-fit ​​base 17 improves the stability of the culture flask body 11 when it is placed or when multiple culture flask bodies 11 are stacked. When stacking, when the snap-fit ​​base 17 is aligned and placed on the upper end of the connecting seat 12, the lower end of the snap-fit ​​base 17 is connected to the positioning post 21. The positioning post 21 is aligned with the circular groove 19 in the connecting seat 12 to ensure that the two culture flask bodies 11 are on the same vertical line when stacked. In a straight line, positioning is more convenient, and multiple culture flasks 11 are on the same plane during stacking, saving space and improving the neatness of stacking. The snap-fit ​​base 17 is aligned and placed on the upper end of the connector 12. At this time, the bottle cap 23 extends vertically into the storage groove 25 opened in the culture flask body 11. The storage groove 25 and the anti-slip texture 24 on the outside of the bottle cap 23 are compatible. When the bottle cap 23 is inserted into the storage groove 25, it is not easy for the bottle cap 23 to be rotated or loosened due to bumps and friction, thereby reducing the risk of liquid leakage and contamination, which helps to ensure the purity and accuracy of cell culture.

[0029] To address the problems existing in the prior art, this utility model provides an insertable anti-tipping stackable cell culture flask. When multiple culture flask bodies 11 need to be moved or stacked in an incubator, align the lower end of one culture flask body 11 with the lower end of another culture flask body 11, and press the two pressing rods 13 towards the center. At this time, align the locking base 17 with the upper end of the connecting seat 12, release the two pressing rods 13, and under the action of the return spring 16, the two pressing rods 13 will slide back to their original position. The two pressing rods 13 will then engage the locking mechanism. The connecting rod 14 slides and engages with the engaging base 17 to allow two culture flask bodies 11 to be stacked, effectively preventing the culture flasks from tipping over during stacking. This improves the stability of the culture flask stacking operation and reduces the risk of culture medium leakage and cell sample damage caused by tipping over. When one of the culture flask bodies 11 needs to be retrieved, simply press the pressing rod 13 again to release the engagement between the connecting rod 14 and the engaging base 17, and the culture flask body 11 can be easily removed. The operation is relatively simple and convenient, which helps to improve the work efficiency of the experimental personnel.

[0030] Working principle:

[0031] The first step is to provide a suitable environment for cell growth by introducing cells and the culture medium required for their growth into the culture bottle body 11 in the experimental environment. The culture bottle body 11 is made of transparent material, and the cell growth stage can be directly observed through the culture bottle body 11. During use, the culture bottle body 11 is opened and closed by twisting the bottle cap 23. When holding and twisting the bottle cap 23, the anti-slip texture 24 connected to its surface provides anti-slip properties.

[0032] The second step involves moving multiple culture flask bodies 11 or stacking them in an incubator (the incubator can be set to a suitable temperature). Align one culture flask body 11 with the lower end of another. Then, press the two pressing rods 13 towards the center (near one end of the ring 15). (The two pressing rods 13 are compatible; when they slide simultaneously, one rod slides into the other, saving space.) Align the snap-fit ​​base 17 with the connecting seat. At the upper end of 12, releasing the two pressing rods 13 causes them to slide back to their original position under the force of the return spring 16. The two pressing rods 13 then drive the locking rod 14 to slide and engage in the locking base 17, thus enabling the stacking of the two culture flask bodies 11. This effectively prevents the culture flasks from tipping over during stacking, improving the stability of the stacking operation and reducing the risk of culture medium leakage and cell sample damage caused by tipping over. When one of the culture flask bodies 11 needs to be used, simply press the pressing rod 13 again to release the locking rod 14 from the locking base 17. The culture flask body 11 can be easily removed, making the operation relatively simple and convenient, which helps improve the work efficiency of the experimenters. The rubber pad 18 on the outer sleeve of the snap-fit ​​base 17 improves the stability of the culture flask body 11 when it is placed or when multiple culture flask bodies 11 are stacked. Furthermore, during the stacking operation, when aligning the snap-fit ​​base 17 with the upper end of the connecting seat 12, the lower end of the snap-fit ​​base 17 is connected to a positioning post 21. Aligning the positioning post 21 with the circular groove 19 in the connecting seat 12 ensures that the two culture flask bodies 11 are on the same vertical line when stacked. To facilitate positioning and ensure that multiple culture flasks 11 are on the same plane during stacking, thus saving space and improving stacking neatness, the snap-fit ​​base 17 is aligned and placed on the upper end of the connector 12. At this time, the bottle cap 23 extends vertically into the storage groove 25 inside the culture flask 11. The storage groove 25 and the anti-slip texture 24 on the outside of the bottle cap 23 are compatible. When the bottle cap 23 is inserted into the storage groove 25, it is less likely to be rotated or loosened due to bumps and friction, thereby reducing the risk of liquid leakage and contamination, which helps to ensure the purity and accuracy of cell culture.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
