Abstract:
A nozzle capable of removing a surplus liquid material, which is adhered to outer surfaces of the nozzle and which affects a discharge operation, without undergoing a special process, and a liquid material discharge device provided with the nozzle. The nozzle ( 1 ) includes a body ( 2 ) having a liquid inflow space, and a discharge tube ( 4 ) communicating with the liquid inflow space and extending downwards from the body ( 2 ). A liquid removing member ( 16 ) is disposed at a lower end of the body ( 2 ) in a state laterally surrounding the discharge tube ( 4 ), and the liquid removing member ( 16 ) includes a groove-like space ( 15 ) that is formed between adjacent to of plural surrounding surfaces ( 10 ), and that generates capillary force acting in a direction laterally away from the discharge tube ( 4 ).

Claim (Index 1):
A liquid material discharge device comprising;\n a nozzle for discharging a liquid material, the nozzle comprising a body having a liquid inflow space, and a discharge tube communicating with the liquid inflow space and extending downwards from the body, a liquid chamber, a valve seat attached at the bottom of the liquid chamber and through which a communication hole is formed to penetrate for communication between the liquid chamber and the discharge tube, a rod of which an end portion moves up and down in the liquid chamber, a driver unit for driving the rod in an up-and-down direction, and a reservoir storing the liquid material and communicated with the liquid chamber, wherein the liquid material discharge device discharges the liquid material in the form of droplets by advancing the rod toward the valve seat, wherein a liquid removing member is disposed at a lower end of the body in a state laterally surrounding the discharge tube, the liquid removing member includes a plurality of surrounding surfaces that surround a lateral surface of the discharge tube, and a groove that is formed adjacent to the plurality of surrounding surfaces, and that generates capillary force acting in a direction laterally away from the discharge tube and holds the liquid material removed from outer surfaces of the discharge tube, the groove is constituted by a pair of guide surfaces that are disposed in an opposing relation and a flat outer surface of the body which is orthogonal to the pair of guide surfaces and formed to extend perpendicular to a body axis passing a center of the discharge tube, a distance between the pair of guide surfaces being larger than an outer diameter of the discharge tube, the discharge tube is cylindrical and has an annular flat distal end surface, and the surrounding surfaces generate capillary force acting on the liquid, which climbs along the lateral surface of the discharge tube, in a direction towards a base of the discharge tube in cooperation with the lateral surface of the discharge tube.
