Breathing structure for bottle mouth and bottle cap of cell culture bottle

Abstract

The invention provides breathing structure for a bottle mouth and a bottle cap of a cell culture bottle. The sealing of the bottle cap and the bottle mouth is convenient and reliable, the operation is time-saving and labor-saving, and the efficiency is high due to the structure. The structure comprises the bottle mouth and the bottle cap, wherein a breathing cap with breathing holes is arranged at the top of the bottle cap; the bottle mouth is provided with external threads; the bottle cap is provided with internal threads; and the bottle mouth is mounted at the bottle cap in a threaded sleeving manner. The structure is characterized in that three bulges are uniformly distributed on the external ring surface of the upper end part of the bottle mouth; three bayonets are uniformly distributed on the ring surface corresponding to the internal threads of the bottle cap, close to the breathing cap; a triangular arrowhead mark is arranged at a position where the upper surface of the breathing cap corresponds to one of the three bayonets; the three bulges of the bottle mouth are clamped in the three bayonets of the bottle cap correspondingly; and a breathing cap filter membrane is paved on the internal surface of the breathing cap of the bottle cap.

Description

technical field [0001] The invention relates to the technical field of cell culture devices, in particular to a bottle cap structure of a gas-permeable cell culture bottle. Background technique [0002] The caps of the existing air-permeable cell culture bottles are all connected by threads. Since the threads are located on the inner ring surface, they cannot be observed by the naked eye. Generally, it is judged by human hand whether to tighten them to reach a sealed state. , people need to use a lot of force to distinguish whether it is sealed, the operation is more laborious, and the efficiency is low. Contents of the invention [0003] In view of the above-mentioned problems, the present invention provides a bottle cap structure of a breathable cell culture bottle, which makes the sealing of the bottle cap and the bottle mouth convenient and reliable, saves time and effort in operation, and has high efficiency. [0004] The bottleneck bottle cap structure of the gas-pe...
