Immune cells are commonly known as white blood cells, including innate lymphocytes, various phagocytes, and lymphocytes that can recognize antigens and produce specific immune responses. The in vitro culture of cells and tissues has become an indispensable part of life research and practice. During the culture process, it is usually necessary to use culture bottles that provide an in vitro cell culture environment.

[0003] At present, existing immune cell culture bottles, such as the Chinese patent with publication number CN216073856U, disclose a special culture bottle for immune cell induction, including a bottle body for culturing immune cells, the side walls of the bottle body are sealed, the top of the bottle body is provided with a bottleneck and a ventilation window, and the top of the bottleneck is sealed with a bottle cap; the bottom of the bottle body is provided with a cell attachment growth body for the growth of immune cells, and the surface of the cell attachment growth body is provided with an undulating structure; a sterile filter membrane is provided in the ventilation window, and by providing the cell attachment growth body with an undulating structure on the surface at the bottom of the bottle body, it can increase the cell growth attachment area and improve the cell harvest. However, in the process of cell culture, it is usually necessary to use multiple immune cell culture bottles at the same time.

[0022] See also Figures 1 to 3The utility model provides an immune cell culture bottle, comprising a bottle body 1, which is hollow inside. The bottle body 1 includes two upper and lower parallel upper and lower end surfaces. The parallel upper and lower end surfaces can facilitate the operator to observe the inside of the bottle body 1. One end of the bottle body 1 is contracted toward the center and connected to an inclined bottleneck 11. Two symmetrical contraction parts are provided on the side surfaces of the bottle body 1 on both sides of the bottleneck 11. The two contraction parts are respectively provided with a fixing frame 2 for placing a label and a marking surface 3 for marking. A placement groove is provided in the fixing frame 2. The operator can place the classified label in the placement groove of the fixing frame 2, so that the operator can quickly identify the cells in the bottle body 1 when taking and placing the bottle body 1 again. The marking surface 3 can facilitate the operator to write detailed information of the cells in the bottle body 1. A bottle cap 111 is threadedly connected to the bottleneck 11.

[0023] See also Figures 1 to 3 Preferably, the angle between the straight line where the axis of the bottleneck 11 is located and the plane where the upper end surface of the bottle body 1 is located is 30 to 40 degrees, which neither affects the transfer of liquid into the bottle body 1 nor prevents the liquid in the bottle body 1 from flowing into the bottleneck 11 and affecting cell culture and observation.

[0024] See also Figures 1 to 3 The upper and lower end surfaces of the bottle body 1 are provided with a limit assembly 5, which includes a limit groove 51 symmetrically arranged on the upper end surface, and a limit strip 52 symmetrically arranged on the lower end surface of the bottle body 1 that cooperates with the limit groove 51. The limit strip 52 is symmetrically elastically connected to the limit head 521 (the end of the limit head 521 close to the limit strip 52 is inserted into the limit strip 52, and the limit head 521 in the limit strip 52 is symmetrically provided with an insert block, and the limit strip 52 is provided with a slot that cooperates with the insert block. The insert blocks are slidably arranged in the slot, and an elastic member 6 is provided between the insert block and the slot). The limit groove 51 is provided with a limit hole 511 that cooperates with the limit head 521. By utilizing the limit strip 52 on one bottle body 1 to cooperate with the limit groove 51 on the other bottle body 1, the bottle body 1 can be ensured to be placed stably when stacking the bottles 1 to prevent the stacked bottles 1 from slipping.

[0025] See also Figures 1 to 3 Preferably, the elastic member 6 is a spring to provide return power.

[0026] See also Figures 1 to 3 Preferably, avoidance holes 4 are symmetrically provided on the side surfaces of the bottle body 1. When taking and placing the bottle body 1, in order to facilitate the separation of the stacked bottle bodies 1 from each other, the operator can hold the avoidance hole 4 and pull the bottle body 1 longitudinally, so that the limiting strip 52 on one bottle body 1 can be disengaged from the limiting groove 51 on the other bottle body 1. During the pulling process, the limiting head 521 squeezes the elastic part 6 and separates from the limiting hole 511, so that the bottle body 1 can be removed.

[0027] See also Figures 1 to 3Preferably, a support bar 7 is provided on the upper end surface of the bottle body 1, and the support bar 7 has the same height as the limiting bar 52. A matching hole 71 is provided on the lower end surface of the bottle body 1 to match the support bar 7. When the bottle body 1 is placed alone, the support bar 7 can match with the limiting bar 52 to ensure that the bottle body 1 is placed stably. When the bottle bodies 1 are stacked, the support bar 7 on one bottle body 1 matches with the matching hole 71 on the other bottle body 1 to avoid a gap between the two bottle bodies 1.

[0028] See also Figures 1 to 3 After transferring the liquid into the bottle body 1, tighten the bottle cap 111, and stack several bottles 1. The limiting strip 52 on one bottle body 1 cooperates with the limiting groove 51 on another bottle body 1 to prevent the stacked bottles 1 from sliding, and then they can be transferred to the incubator.

[0029] The present invention provides an immune cell culture bottle, including a limiting assembly, which utilizes a limiting strip on one bottle body to cooperate with a limiting groove on another bottle body to improve the stability of the bottle body when the bottles are stacked, and prevent the stacked bottles from sliding off; the angle between the straight line where the axis of the bottleneck is located and the plane where the upper end face of the bottle body is located is 30 to 40 degrees, which does not affect the transfer of liquid into the bottle body, and can also prevent the liquid in the bottle body from flowing into the bottleneck, affecting cell culture and observation; using a fixed frame and a marking surface, the operator can mark the bottle body at any time. In summary, the beneficial effects of the present invention are: it can improve the stability of the immune cell culture bottles when the immune cell culture bottles are stacked, and prevent the stacked immune cell culture bottles from sliding off, and at the same time, the immune cell culture bottles can be marked at any time.
