Description

Cell culture bottle

Technical Field

The utility model relates to the technical field of cell culture equipment, in particular to a cell culture bottle.

Background

Cell culture, also called cell cloning technology, has become an essential element in life research and practice, and plays an important role in regenerative medicine and disease treatment. Cell culture is a large-scale cloning of cells, and can be carried out from one cell to a simple single cell or a few differentiated multicellular. Some cells can be cultured in a culture bottle, and the cells must be passaged or supplemented with culture medium in the culture process, so that the operator can select to directly pour the culture solution from the bottle mouth or pour the waste liquid from the bottle mouth for convenient experiment operation and saving consumables such as a liquid transfer device.

The bottleneck of the existing cell culture bottle can have partial waste liquid residues when the waste liquid is discharged in the process of passage or liquid exchange, and the waste liquid can be completely poured out only by tilting the bottle body for many times, so that the opening time of the cell culture bottle is too long, and the possibility of cell pollution is increased.

And when the bottle cap is opened, the operation is generally performed in a mode that an operator directly unscrews the latex glove, but the operator often contacts other objects by hands, so that the latex glove is very easy to be polluted by bacteria, when the operator unscrews the bottle cap of the culture bottle by wearing the polluted latex glove, the bottle mouth of the culture bottle is correspondingly polluted, and the bottle mouth pollution of the culture bottle can cause pollution of culture solution in the culture bottle.

Disclosure of Invention

The utility model aims to provide a cell culture bottle which has a simple structure and is easy to operate, the technical effects that waste liquid is poured cleanly without residual liquid at a bottle opening can be achieved, the bottle cap is not directly contacted, and bacteria on hands are not brought to the bottle cap.

In order to achieve the above purpose, the utility model provides a cell culture bottle, which comprises a bottle body, wherein the bottleneck of the upper end part of the bottle body is an arc bottleneck, the upper end of the bottleneck is provided with a cylindrical bottleneck, a detachable bottle cap is connected to the bottleneck, a connecting column is arranged on the bottle cap, and the other end of the connecting column is connected to the same disc.

Preferably, the top end of the bottle opening is provided with threads, and the bottle cap is provided with threads corresponding to the bottle opening.

Preferably, the part of the bottle mouth close to the bottle neck is shaped like a funnel with an inverted cone.

Preferably, the number of the connecting columns is four, the connecting columns are uniformly distributed on the bottle cap, and the connecting columns are connected with the bottle cap through hot melting.

Preferably, the bottle body is rectangular.

Preferably, the connecting column and the disc are made of POM plastic.

Therefore, the utility model adopts the culture bottle outside the circular arc bottleneck, so that the waste liquid is conveniently discharged in the cell culture process, the opening time of the culture bottle is reduced, the risk of cell pollution is reduced, the possibility of cell pollution in the operation process is reduced to a certain extent, the culture bottle is suitable for all cells which need to be cultured by the culture bottle, and the culture bottle has the advantages of good use effect, convenient use and high working efficiency, and the design of the bottle cap ensures that the cell culture bottle cannot introduce other bacteria and impurities to influence the living environment of the cells.

The technical scheme of the utility model is further described in detail through the drawings and the embodiments.

Example 1

As shown in the figure, the utility model provides a cell culture bottle, which comprises a bottle body 1, cells are cultured in the bottle body 1 of the cell culture bottle, and the bottle body 1 is rectangular. The bottleneck 2 at the upper end part of the bottle body 1 is a circular arc bottleneck 2, and the purpose of adopting the circular arc bottleneck 2 is to facilitate the discharge of waste liquid in the cell culture process. The upper end of the bottleneck 2 is provided with a cylindrical bottleneck 3, the part of the bottleneck 3 close to the bottleneck 2 is shaped like a funnel with an inverted truncated cone, and the design of the funnel-shaped bottleneck 3 is convenient for reducing external bacteria and impurities to enter the cell culture flask. The top end of the bottle mouth 3 is provided with threads, the bottle mouth 3 is connected with a detachable bottle cap, the bottle cap 4 is provided with threads corresponding to the bottle mouth 3, when waste liquid is required to be discharged, the bottle cap 4 is opened, and after the waste liquid is poured out, the bottle cap 4 is screwed.

Be equipped with spliced pole 5 on the bottle lid 4, the quantity of spliced pole 5 is four, and spliced pole 5 evenly distributed is on bottle lid 4, and spliced pole 5 passes through hot melt with bottle lid 4 to be connected, and spliced pole 5 is used for connecting bottle lid 4 and disc 6. The other end of the connecting column 5 is connected to the same disc 6, and the disc 6 is used for driving the bottle cap 4 to rotate, so that an operator can open the bottle cap 4 without touching the bottle cap 4, contact with the bottle cap 4 is reduced, and meanwhile the probability that bacteria and impurities enter the cell culture bottle is reduced.
