摘要： Provided is a container, which comprises a container body and a cover and further comprises a variable-pressure component, a metering channel, a liquid extraction channel and an outflow channel. The head of the metering channel is in communication with the variable-pressure component, and the tail thereof is in communication with the outflow channel and the liquid extraction channel. A valve, which is opened when the variable-pressure component is pressurized and is closed when the variable-pressure component is depressurized, is provided between the metering channel and the outflow channel. A valve, which is opened when the variable-pressure component is depressurized and is closed when the variable-pressure component is pressurized, is provided between the metering channel and the liquid extraction channel or within the liquid extraction channel. The metering channel, the liquid extraction channel and the outflow channel are fixed to the cover.

摘要： 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.
