Referring to fig. 1-3, a cell freezing tube includes a tube body 10 and a cover 20. The tube body 10 is used for accommodating cells to be stored and transferred, the tube body 10 is in a straight tube shape, one end of the tube body is open, the other end of the tube body is closed, and the cells are taken out through the open end of the tube body 10. A cap 20 is provided at the open end of the tube 10 to close the tube 10, and the cap 20 of this embodiment includes a cap body 21, a sealing layer 22, and a frangible block 23. Wherein, the cover body 21 comprises a top part and a ring-shaped side wall, the top part of the cover body 21 is provided with an opening, and the opening can comprise all or part of the top area of the cover body 21; the sealing layer 22 is provided on the top of the lid body 21 and seals the opening thereof. The easily breaking block 23 is disposed on the top of the cover 21 in an easily detachable manner, that is, the easily breaking block 23 is disposed on the top of the cover 21 in an openable manner, and the connection between the easily breaking block 23 and the cover 21 is completely or partially separated by applying a force to one side of the easily breaking block 23. The easy-breaking block 23 is configured to shield one side of the sealing layer 22 facing the outer side of the cover 21, and when the easy-breaking block 23 is not broken, the sealing layer 22 is completely shielded and not exposed to the outside, so as to prevent pollution and damage; after the easily breaking pieces 23 are broken, the sealing layer 22 is partially or completely exposed, so that a needle or the like can be inserted through the sealing layer 22 to access the cells in the tube 10. The connection surface of the easy-breaking block 23 and the cover 21 is polygonal, such as triangular, rectangular, etc. The polygonal easy-breaking block 23 is easy to break when acting force in one side direction is applied, and is not easy to break away from the cover body 21 when acting force in the circumferential direction is applied, so that accidental breakage of the easy-breaking block 23 caused by a production link or a situation of screwing the cover 20 due to misoperation is prevented.
In one embodiment, the connection surface of the easy-breaking block 23 and the cover 21 is triangular. The triangular connecting surface has stronger structural stability, is easy to design and manufacture, has lower cost, is difficult to separate from the cover body 21 accidentally due to the easy breaking block 23, and has better use effect.

After the breakable blocks 23 are broken, the sealing layer 22 is exposed, and the non-sealing layer 22 on the top of the cover 21 is not exposed, so as to prevent contamination and prevent the needle tip from being mixed with the sealing layer 22 and not inserted into the sealing layer 22. Of course, in other embodiments, the connection surface of the breaking-off blocks 23 may be located within the sealing layer 22 and not necessarily inscribed.
In one embodiment, the breakable blocks 23 are integrally injection-molded with the cover 21. It should be noted that, during injection molding, the connection between the cover body 21 and the easy-breaking block 23 is configured to be weak, so that the easy-breaking block 23 is separated from the cover body 21.

When needed, the cover 20 can be screwed to the outer side wall of the open end of the tube body 10, the sealing performance in the tube body 10 is ensured, and only the cover 20 needs to be rotated reversely during disassembly, so that the integral assembly and disassembly of the cover 20 are facilitated. Meanwhile, the direction of the acting force required by the cap 20 screwed in and out of the thread is not consistent with that of the polygonal easy-breaking block 23, so that the generation of misoperation is reduced.
In one embodiment, the cover 21 is provided with an anti-slip groove 24 on its outer wall surface. The anti-slip groove 24 increases friction to facilitate rotation of the lid 20.
In one embodiment, the outer wall of the tube 10 is provided with graduations 11 and a writing surface plate 12 is fixed thereto. The scale marks 11 are convenient for users to visually know the cell stock in the tube body 10, and the writing panel 12 is convenient for the users to mark each cell cryopreservation tube.
The closed end of the cell freezing tube is generally spherical and is not easy to be directly placed. In one embodiment, the cell cryopreservation tube further comprises a support plate 30. The blind end of body 10 is located to backup pad 30, and backup pad 30 one end is fixed with body 10, and the other end extends and surpasss the body 10 bottom to body 10 bottom direction for cell cryopreserving pipe accessible backup pad 30 is upright to be placed. A reinforcing rod 31 is fixedly connected between the supporting plate 30 and the tube 10 to reinforce the structure of the supporting plate 30.
The embodiment of the application also discloses a using process of the cell cryopreservation tube: when cells in the tube 10 need to be taken out, the breakable block 23 can be broken, the breakable block 23 is separated from the cover 21, and at least a part of the sealing layer 22 is correspondingly exposed; inserting the needle of the syringe for taking cells into the sealing layer 22, wherein the needle can penetrate through the sealing layer 22 and penetrate into the tube 10; the cell in the tube 10 can be taken out by operating the syringe.
