[0023] Reference Figure 1-6 The cell culture flask anti-contamination sealing cap structure includes a flask body 1, a flask mouth 2 fixedly connected to one side of the flask body 1, a threaded opening 3 fixedly connected to the top of the flask mouth 2, a flask cap 4 threadedly connected to the top of the threaded opening 3, a threaded groove provided on the inner wall of the flask cap 4, a cleaning cap 5 fixedly connected to the top of the flask cap 4, a cleaning groove 7 provided on the top of the cleaning cap 5, the cleaning groove 7 being annular in shape, a top plate 6 rotatably connected to the top of the cleaning cap 5 via a pivot, the top plate 6 being circular in shape, a first cleaning pad 8 fixedly connected to one side of the inner wall of the cleaning groove 7, a second cleaning pad 9 fixedly connected to the other side of the inner wall of the top cleaning groove 7, both the first cleaning pad 8 and the second cleaning pad being made of rubber, an installation ring fixedly connected to the outer wall of the flask mouth 2, and a fixing component provided at the top of the installation ring.

[0024] To address the difficulty of cleaning the neck 2 of cell culture flasks, when using a whitened culture flask, the cap 4 can be unscrewed from the threaded opening 3, and the culture medium can be poured into the threaded opening 3. The culture medium will flow into the body 1 through the threaded opening 3 and the neck 2, providing a suitable environment for the culture medium. Then, the cap 4 can be flipped over so that the other end of the cap 4 is aligned with the threaded opening 3. The top plate 6 can then be flipped open to one side so that the cleaning groove 7 is aligned with the threaded opening 3, and disinfectant can be added to the cleaning groove 7. After the disinfectant comes into contact with the first cleaning pad 8 and the second cleaning pad 9 made of sponge material, the first cleaning pad 8 and the second cleaning pad 9 will be soaked. Then, the cleaning cap 5 is inserted into the threaded opening 3, and by rotating the cleaning cap 5, the first cleaning pad 8 and the second cleaning pad 9 will rotate together. The cleaning solution on the first cleaning pad 8 and the second cleaning pad 9 can be used to clean the threaded opening 3, keeping the threaded opening 3 clean and preventing bacterial contamination. Finally, the cap 4 is flipped over so that the cap 4 is screwed onto the threaded opening 3, thereby sealing the neck 2 and the threaded opening 3.

[0025] Reference Figure 5 The fixing assembly includes a fixing rod 10, which is rotatably connected to one side of the mounting ring via a rotating shaft. A mounting plate is fixed to one side of the top end of the fixing rod 10, and a spring 11 is fixed to the bottom of the mounting plate. A pressure plate 12 is fixed to the bottom of the spring 11 and is attached to the top end of the top plate 6. The fixing assembly is provided in three sets and is distributed circumferentially at the top end of the mounting ring.

[0026] After the bottle cap 4 is screwed on, the top plate 6 can be flipped to the top of the cleaning cover 5 to close the cleaning groove 7. Then, rotate the fixing rod 10 to flip the three sets of fixing rods 10 upward until the pressure plate 12 contacts the top of the top plate 6. The pressure of the spring 11 can make the three sets of pressure plates 12 fit tightly against the top of the top plate 6, thereby providing a downward pushing force for the top plate 6, the cleaning cover 5 and the bottle cap 4, so that the bottle cap 4 can be installed securely.

[0027] Reference Figure 3 The top of the pressure plate 12 is fixedly connected to a vertical rod 13, the top of the vertical rod 13 penetrates the top of the mounting plate, and a horizontal block is fixedly connected to the top of the vertical rod 13.

[0028] By setting a vertical rod 13 at the top of the pressure plate 12, the vertical rod 13 can be used to limit the movement trajectory of the pressure plate 12 when the pressure plate 12 moves up and down, thus preventing the pressure plate 12 from deviating.

[0029] Reference Figure 3 A gasket 14 is fixed to the bottom of the pressure plate 12. The gasket 14 is made of rubber and its bottom is attached to the top of the top plate 6.

[0030] By providing a rubber gasket 14 at the bottom of the pressure plate 12, the top of the top plate 6 can be easily protected by the gasket 14 when the pressure plate 12 is attached to the top of the top plate 6.

[0031] Reference Figure 3 A support plate 15 is fixedly connected to one side of the fixing rod 10. A limiting ring 16 is provided at the top of the support plate 15. The limiting ring 16 is sleeved on the outer wall of the three sets of fixing rods 10. A protrusion 17 is fixedly connected to one side of the fixing rod 10. The protrusion 17 is made of rubber and is located at the top of the limiting ring 16.

[0032] By setting a support plate 15 on one side of the fixing rod 10, when the bottle cap 4 and cleaning cap 5 are fixed by the three sets of fixing rods 10, the limiting ring 16 is put on the outer wall of the three sets of fixing rings and pushed downward. When the limiting ring 16 passes the protrusion 17, it will squeeze the rubber protrusion 17, so that the limiting ring 16 passes the protrusion 17. When the bottom of the limiting ring 16 contacts the top of the support plate 15, the position of the three sets of fixing rods 10 can be fixed.

[0033] Reference Figure 4 The inner wall of the bottle cap 4 is fixedly connected to a pad 18, and the bottom of the bottle cap 4 is fixedly connected to a sealing pad 19. Both the pad 14 and the sealing pad 19 are made of rubber.

[0034] By providing a gasket 18 on the inner wall of the bottle cap 4, a seal can be provided at the connection between the top of the threaded opening 3 and the inner wall of the bottle cap 4 when the bottle cap 4 is screwed on. By providing a sealing gasket 19, a seal can be provided at the bottom of the bottle cap 4.

[0035] Working Principle: To address the difficulty of cleaning the neck 2 of cell culture flasks, when a washing culture flask is needed, the cap 4 can be unscrewed from the threaded opening 3, and the culture medium can be poured into the threaded opening 3. The culture medium will flow into the flask body 1 through the threaded opening 3 and the neck 2, thus providing a suitable environment for the culture medium. Then, the cap 4 can be flipped over so that the other end of the cap 4 aligns with the threaded opening 3. Next, the top plate 6 can be flipped open to one side so that the cleaning groove 7 aligns with the threaded opening 3, and disinfectant solution can be added to the cleaning groove 7. The disinfectant solution, upon contact with the first and second sponge cleaning pads 8 and 9, will... The first cleaning pad 8 and the second cleaning pad 9 are soaked. Then, the cleaning cap 5 is inserted into the threaded opening 3, and rotating the cleaning cap 5 causes the first and second cleaning pads 8 and 9 to rotate together. The cleaning solution on the first and second cleaning pads 8 and 9 cleans the threaded opening 3, keeping it clean and preventing bacterial contamination. Then, the bottle cap 4 is flipped over and screwed onto the threaded opening 3, thus sealing the bottle opening 2 and the threaded opening 3. A gasket 18 is provided on the inner wall of the bottle cap 4 to provide a seal at the connection between the tip of the threaded opening 3 and the inner wall of the bottle cap 4 when the cap 4 is screwed on. A sealing pad 19 is placed to provide a seal to the bottom of the bottle cap 4. After the bottle cap 4 is screwed on, the top plate 6 can be flipped to the top of the cleaning cover 5 to close the cleaning groove 7. Then, the fixing rod 10 is rotated to flip the three sets of fixing rods 10 upwards until the pressure plate 12 contacts the top of the top plate 6. The compression of the spring 11 makes the three sets of pressure plates 12 fit tightly against the top of the top plate 6, thereby providing a downward pushing force to the top plate 6, the cleaning cover 5, and the bottle cap 4, so that the bottle cap 4 can be installed securely. The upright rod 13 limits the movement trajectory of the pressure plate 12 to prevent the pressure plate 12 from shifting. A rubber pad 14 is provided at the bottom of 2. When the pressure plate 12 is attached to the top of the top plate 6, the pad 14 can provide protection for the top of the top plate 6. By providing a support plate 15 on one side of the fixing rod 10, when the three sets of fixing rods 10 fix the positions of the bottle cap 4 and the cleaning cap 5, the limiting ring 16 is put on the outer wall of the three sets of fixing rings and pushed downward. When the limiting ring 16 passes the protrusion 17, it will squeeze the rubber protrusion 17, so that the limiting ring 16 passes the protrusion 17. When the bottom of the limiting ring 16 contacts the top of the support plate 15, the positions of the three sets of fixing rods 10 can be fixed.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
