Description

A sealed liquid bottle

technical field

The utility model belongs to the technical field of chemical containers, in particular to a sealed liquid bottle.

Background technique

Liquid bottle is a kind of more commonly used chemical container, is used to hold the reagent for experiment. Liquid bottles are widely used in schools, hospital laboratories, or factory testing rooms. A general liquid bottle includes a bottle body and a cover body. The bottle body is generally cylindrical, and the top of the bottle body is an inwardly shrinking bottleneck, and a bottle cap is arranged in the bottleneck. The bottle cap includes: a horizontal cap and an inverted frustum-shaped cap core. The cap core is in close contact with the inner side of the bottle mouth.

Due to the poor airtightness of the existing liquid bottle. When the liquid bottle is accidentally scratched, the liquid bottle is knocked over on the test bench, and the chemical reagents in the liquid bottle will spill out, burn or burn or corrode human skin, and also pollute the test bench.
