Precision dispensing bottle

Abstract

The invention discloses a precision dispensing bottle. The precision dispensing bottle comprises a bottle body, a swiveling cover, a bottle cap, and a plug assembly, wherein the interior of the bottle body is of a cavity structure to hold a liquid; an upper portion of the bottle body is provided with a bottle mouth portion extending upwards; the swiveling cover covers and is in threaded connection with the bottle mouth portion; the bottle cap sleeves the swiveling cover; the swiveling cover is upwards inserted into the bottle cap, and in interference connection with an inner wall of the bottle cap; an insertion rod is arranged on the inner wall of the bottle cap; and the insertion rod is inserted into the plug assembly arranged in the bottle body after downwards and orderly passing through the swiveling cover and the bottle mouth, such that the plug assembly is separated from a liquid inlet formed in the top of the bottle mouth. The precision dispensing bottle is simple in structure, and capable of realizing quantitative liquid pouring by means of simple and convenient operations.

Description

technical field [0001] The invention relates to a dispensing bottle, in particular to a precision dispensing bottle. Background technique [0002] In the actual production life and teaching experiment process, various liquid volumetric bottles are often used to store liquid solvents, such as the solvent bottles used in teaching experiments, and the seasoning used to hold liquid seasonings such as wine, vinegar, and soy sauce in daily life. In the actual use process, seasoning bottles generally rely on human experience to pour out an appropriate amount of liquid, and pour out liquid based on experience, which has the defect of inaccurate pouring out of liquid, and cannot finely control the volume of pouring out liquid; in addition, the teaching experiment The volumetric flask used in the test is quantified by engraving a scale marking the volume on the wall of the bottle, and observing the liquid level in the bottle and the scale with human eyes. However, there are also error...
