Provided is a container, which comprises a container body (1) and a cover (2) and further comprises a variable-pressure component (3), a metering channel (8), a liquid extraction channel (11) and an outflow channel (12). The head of the metering channel (8) is in communication with the variable-pressure component (3), and the tail thereof is in communication with the outflow channel (12) and the liquid extraction channel (11). A valve, which is opened when the variable-pressure component (3) is pressurized and is closed when the variable-pressure component is depressurized, is provided between the metering channel (8) and the outflow channel (12). A valve, which is opened when the variable-pressure component (3) is depressurized and is closed when the variable-pressure component is pressurized, is provided between the metering channel (8) and the liquid extraction channel (11) or within the liquid extraction channel (11). The metering channel (8), the liquid extraction channel (11) and the outflow channel (12) are fixed to the cover (2). The container is simple in structure, convenient to use and accurate in metering, and can be used for liquid containers, metering tools, intelligent kitchen systems, and cooking robots, etc. |
