Claim:
1. A container, comprising a container body, characterized by further comprising a pressure transfer channel, a control valve, a liquid taking channel and an outflow channel; the pressure transfer charnel transferring to the control valve variation of positive and negative pressures applied to the pressure transfer channel by an external variable pressure part; the control valve comprising a valve body and a valve core, and under the positive and negative pressures, the valve core axially reciprocating in the valve body; one end of the valve body being in communication with the pressure transfer channel, the other end being provided with a pressure relief opening, and sidewalls being provided with at least two interfaces; outer sides of the interfaces being respectively in communication with the outflow channel and the liquid taking channel, and inner sides leading to an outer side face of the valve core; the valve core being provided with an internal channel, an outer-end opening of the internal channel being in communication with the pressure transfer channel, and an inner-end opening being located on the outer side face of the valve core; the valve core, under the positive pressure, moving to a position where interfaces through which the inner-end opening is in communication with the outflow channel are connected, under the negative pressure, moving to a position where interfaces through which the inner-end opening is in communication with the liquid taking channel are connected, and in the absence of pressure, moving to a position where the inner opening and interfaces on the valve body are not connected; one end of the liquid taking channel being in communication with the corresponding interface on the valve body, and the other end leading to the bottom inside the container body; and one end of the outflow channel being in communication with the corresponding interface on the valve body, and the other end leading to the outside of the container body.
