TECHNICAL FIELD
[0001] The utility model relates to laboratory appliance technical field especially, relates to a laboratory washing bottle with sealing ring. BACKGROUND
[0002] The washing bottle is a container used for containing cleaning solution in the chemical laboratory, which is used for cleaning laboratory instruments, quantitative transfer of solution, washing and quantitative transfer of precipitate, etc.
[0003] The most common problem of the washing bottle in use is air leakage. When the washing bottle with air leakage is squeezed, no water comes out or the water comes out weakly. There are two main reasons for air leakage: one is that the sealing between the suction tube and the bottle cap is not good, and the other is that the sealing between the bottle cap and the bottle body is not good.
[0004] The sealing between the suction tube and the bottle cap can be enhanced by integrally forming the suction tube and the bottle cap. This type of washing bottle has been widely produced and used. Because the bottle cap needs to be opened frequently to inject washing liquid during the experiment, the bottle cap and the bottle body are connected movably, so a suitable method is needed to enhance the sealing.
