Quantitative container

Abstract

The invention relates to the technical field of liquid containers, in particular to a quantitative container. The quantitative container comprises a container and a quantitative cavity, wherein a liquid storage cavity and a guide post are arranged in the container; the quantitative cavity is rotatably arranged in the guide post; a liquid outlet of the liquid storage cavity is arranged on the guide post; the quantitative cavity is provided with capacity scale marks and a quantitative cavity liquid inlet; and the quantitative cavity liquid inlet and the liquid outlet of the liquid storage cavity are controlled to be correspondingly communicated and staggered and closed by rotating the quantitative cavity. The invention adopts the following structure arrangement: when the quantitative container is used, the liquid inlet of the quantitative cavity and the liquid outlet of the liquid storage cavity are controlled to be in a corresponding communication state by rotating the quantitative cavity, and the liquid stored in the liquid storage cavity can flow into the quantitative cavity; and the liquid amount of the inflow is convenient to observe according to the capacity scale marks, and after the required liquid amount is reached, the liquid inlet of the quantitative cavity and the liquid outlet of the liquid storage cavity are controlled to be in a staggered closed state by rotating the quantitative cavity, so that the liquid stored in the liquid storage cavity stops flowing into the quantitative cavity. The invention is simple in structure, convenient to operate and ingenious in design.

Description

technical field [0001] The invention relates to the technical field of liquid containers, in particular to a quantitative container. Background technique [0002] In daily life, it is often necessary to use various liquids quantitatively, such as the preparation of medicines, the synthesis of chemical experiments, etc. The traditional method is to use a measuring cup. When using it, pour liquid from a container into a vector cup. After observation Manual quantification, but this method has the following disadvantages: 1) Because sometimes the liquid is poured too much, sometimes it is poured less, so it is very troublesome to observe and repeat the quantification repeatedly during manual quantification; 2) In order to perform quantitative modulation at any time, it is necessary to The container is carried together with the measuring cup, which is inconvenient to carry; 3) pouring the liquid in the container into the measuring cup is likely to cause secondary pollution; 4) Fo...
