<p>Object: To provide a viscous liquid material discharging method and apparatus which can minimize generation of the problem of wear of a sealing member due to friction, and which can minimize a rotational force required at the time of starting discharge of a highly-viscous liquid material. Solving Means: In the viscous liquid material discharging method and the liquid material discharging apparatus for carrying out the method, the apparatus comprises a screw having a helical blade which is axially provided over a surface of a rod-like member, a rotation driving mechanism for rotating the screw, a main body having a screw insertion bore in which the screw is inserted, a liquid material supply port formed in a lateral side of the screw insertion bore, and a liquid material supply flow passage communicating with the liquid material supply port, a sealing member which is disposed in the screw insertion bore and through which the screw penetrates, and a nozzle mounted to the main body and communicating with the screw insertion bore. A liquid-arresting space is formed above the liquid material supply port in the screw insertion bore. The liquid material is supplied while avoiding the sealing member from being wetted with the liquid material, and the screw is rotated in a forward direction to discharge the liquid material from the nozzle.</p> |
