[0002] A culture bottle is a consumable commonly used in cell biology experiments. A culture bottle consists of a bottle body and a bottle cap. The bottle body of the culture bottle is generally made of a transparent material, and the bottle cap is made of a non-transparent material. The culture bottle is generally placed in a cell culture incubator. The plastic culture bottle is convenient for directly observing the cell state and is convenient for controlling temperature, carbon dioxide, and humidity in the incubator.

[0003] In the existing cell culture, the bottle caps of plastic triangular cell culture bottles are generally integral, the bottle cap and the bottle body are separated, and the bottle cap and the bottle body are usually connected by threads. When performing operations on multiple culture bottles simultaneously, it is necessary to remove the bottle caps of the culture bottles before proceeding with the operations. In this way, the removed bottle caps of different culture bottles are easily confused. It is difficult to unscrew the bottle cap of the culture bottle with one hand during the process of unscrewing, and it needs to be rotated multiple times. If the bottle cap is rotated excessively or held unsteadily, the bottle cap may slip off.

[0004] Therefore, there is an urgent need to provide a triangular cell culture bottle cap, which, compared with the prior art, can avoid the confusion of bottle caps, the difficulty of unscrewing the bottle caps, and the detachment of the bottle caps caused by excessive rotation during the unscrewing process.
