A container used in daily life comprises a container main body, and a pressure channel composed of a pressure transmission channel, a removal channel and an outflow channel connected in series. The pressure channel, attached to a wall of the container main body, has one end in communication with the removal channel and the other end connectable to a pressurizing component provided externally. The pressure transmission channel transmits pressure exerted on the inside of the pressure transmission channel by the pressurizing component provided externally, via a pressure transmission medium inside the channel. A wall of the removal channel is provided with a one-way valve allowing the contents to flow into the pressure channel. The one-way valve opens at the bottom on the inside of the container main body. The outflow channel is used for flowing out the contents from the container and preventing the contents flowing back.
