Abstract
Provided is a self-metering container, an initial positioning device thereof and an initial positioning method. The container comprises a container body, a variable pressure component, a metering channel and an outflow channel. When the variable pressure component is depressurized, contents in the container body enter the metering channel; and when the variable pressure component is pressurized, the contents in the metering channel flow outwards via the outflow channel. The container further comprises an initial positioning device. The initial positioning device comprises a backflow cavity, a backflow channel and a component capable of closing the backflow channel. The backflow cavity is in communication with the variable pressure component and the initial end of the metering channel. The initial end of the metering channel is higher than the bottom of the backflow cavity. The backflow channel is in communication with the bottom of the backflow cavity and the container body.
