Abstract

The present invention discloses an intermediate bulk container and a valve opening/closing device therefor. The container comprises a base, side plates, and a valve installed at the bottom of the container. The valve opening/closing device comprises a handle, a motion-transferring device, a valve opening/closing mechanism and a clutch device. The handle is installed on the side plate and is connected to the motion-transferring device. The motion-transferring device is used to transfer the actions acting on the handle to the valve opening/closing mechanism so as to achieve opening/closing of the valve. The clutch device is used to engage the motion-transferring device with the valve opening/closing mechanism or disengage the motion-transferring device from the valve opening/closing mechanism. According to the valve opening/closing device of the present invention, the operating handle is provided at appropriate position of the side plate of the container, thereby avoiding actions such as bending over or squatting on the ground while opening/closing the valve, thus it is convenient for use and can prevent the valve from being opened by mistake.
