A container and method for taking out contained product. The container comprises a container body, a pressure transfer channel, a control valve, a liquid taking channel and an outflow channel, the control valve contains a moving part. The moving part is at different positions along with variation of pressure applied to a variable pressure part, and connection and disconnection of the channels which between the pressure transfer channel and the outflow channel and between the liquid taking channel and the pressure transfer channel are determined by three positions of the moving part. The container can quantitatively take out contained product, is simple in structure and avoid the product to be oxidized or polluted.

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; andone 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. 2. The container according to claim 1, characterized in that: the body of the pressure transfer channel is located outside the container body or on an outer wall, and a channel wall is a transparent wall marked with scales thereon. 3. The container according to claim 1, characterized in that: internal diameters of the internal channel, the interfaces and the liquid taking channel or the outflow channel are substantially the same. 4. The container according to claim 1, characterized in that: the container body has a plurality of spaces therein, respectively containing different contained products; each space is in communication with the corresponding interface on the valve body through a respective liquid taking channel; and the interfaces in communication with the liquid taking channel are located on the same radial plane. 5. The container according to claim 1, characterized in that: the inner-end opening of the valve core is an annular slot. 6. The container according to claim 1, characterized in that: the control valve is internally provided with an elastic part, and the elastic part enables the valve core to return to the position where the inner-end opening of the valve core and the interfaces on the valve body are not connected. 7. The container according to claim 6, characterized in that: the elastic part is a spring located at an end portion of the valve core. 8. The container according to claim 1, characterized in that: the valve body is internally provided with a blocking device, to block the valve core from continuously moving after the inner-end opening communicates with the corresponding interface due to the positive and negative pressures. 9. The container according to claim 1, characterized in that: the pressure relief opening leads to the outflow channel. 10. The container according to claim 1, characterized in that: the variable pressure part is an airbag with a springback function or a piston that can be pushed or pulled in the pressure transfer channel. 11. A method for taking out a contained product in a container, a containing device used comprising a variable pressure part, a pressure transfer channel, a control valve, a liquid taking channel and an outflow channel, wherein the variable pressure part, the pressure transfer channel and the control valve are in communication with each other in sequence, and the liquid taking channel and the outflow channel are connected with side faces of the control valve; the method comprising: A. pressurizing the pressure transfer channel by using the variable pressure part, to push a valve core in a valve body to move, so that the control valve communicates with the pressure transfer channel and the outflow channel and the contained product in the pressure transfer channel and the control valve flows outwards along the outflow channel;B. stopping pressurizing after a required amount of the contained product is taken out, and the contained product stopping flowing out;C. making the valve core in the control valve return to a position where the pressure transfer channel and the outflow channel as well as the liquid taking channel and the pressure transfer channel are disconnected;D. decompressing the pressure transfer channel by using the variable pressure part, to push the valve core in the valve body to move, so that the pressure transfer channel communicates with the liquid taking channel and the contained product in the container body flows out into the pressure transfer channel;E. after decompression is stopped, the contained product in the container body stopping flowing out into the pressure transfer channel; andF. making the valve core in the control valve return to the position where the pressure transfer channel and the outflow channel as well as the liquid taking channel and the pressure transfer channel are disconnected. 12. The method according to claim 11, characterized in that: steps C, D, E, and F are automatically completed after completion of steps A and B.
