PIGMENT DISPENSER

Provided is a pigment injector (100) capable of supplementing and injecting a pigment in a spray can, where gas is compressed, as an economical and simple structure. A pigment injector (100) comprises: a supporter (70) having a space (60) between an upper plate (40) and a lower plate (50); a pigment compressing member (30) comprising a screw (31) penetrating the upper plate of the supporter and being fixated to be able to ascend and descend towards the orthogonal direction of the upper plate, a piston (32) fixated in the lower end of the screw, and a handle (33) fixated in the upper end of the screw; a plate shaped holder (80) being installed in the lower surface of the upper plate, where the piston is positioned, to have a predetermined gap with the upper plate while leaving the piston therebetween, and having a U shaped cutting unit (81); an adjustable support (90) installed in the upper surface of the lower plate to be able to adjust a gap with the plate shaped holder; a circular groove (36) in which an edge of the U shaped cutting unit (81) is inserted along the external peripheral surface of a main body part; and a pigment container (35) including a compressing path (37), in which the piston in a sealed state is slid, and an outlet (38) formed in the end part of the compressing path.
