The present invention relates to a dispenser for impression materials. The dispenser comprises: a first and a second cylinder accommodating a fluid supposed to be pressed out a first and a second extruding tube formed on the first and second cylinders respectively a plurality of holding pieces which are members surrounding the extruding tubes and having a curvature of a circular arc with a fixed diameter, and spaced from each other and therein a plurality of rooted serration units extended in the direction parallel to a plane, which is at right angle to the direction the fluid is pressed out, are formed on each inward-facing surface a mixing tube connected to the first and second extruding tubes and receiving the fluid pressed out through the extruding tubes and allowing the same to pass through a mixing screw arranged in the mixing tube so as to mix the fluid and a coupling adapter which is fixed on the holding pieces while accommodating a part of the mixing tube therein so as to keep a coupling between the mixing tube and the first and second extruding tubes and has a plurality of serration plate units, which are slid into the rooted serration units of the respective holding pieces and tightly coupled to the rooted serration units, on the outer circumferential surface thereof. The dispenser for impression materials of the present invention enables a very strong coupling between a cartridge and a mixing tip, does not cause shaking at a join even long-term use, and is safe from a leakage of impression materials, thereby being highly reliable and heightening the results of treatment.COPYRIGHT KIPO 2016본 발명은 인상재 디스펜서에 관한 것이다. 이는, 압출할 유체를 수용하는 제 1,2실린더와 상기 제 1,2실린더에 각각 형성된 제 1,2압출튜브와 상기 압출튜브를 둘러싸되 일정직경을 갖는 원호의 곡률을 가지고 서로에 대해 이격 배치된 부재로서, 각각의 내향면에는, 유체의 압출방향에 직교하는 평면과 평행한 방향으로 연장된 다수의 고정톱니부가 형성되어 있는 다수의 홀딩편과 상기 제 1,2압출튜브에 연결되며 압출튜브를 통해 압출되는 유체를 받아들여 통과시키는 믹싱튜브와 상기 믹싱튜브의 내부에 구비되며 유체를 혼합하는 믹싱스크류와 상기 믹싱튜브를 그 내부에 일부 수용한 상태로 상기 홀딩편에 고정되어 제 1,2압출튜브에 대한 믹싱튜브의 결합을 유지하는 것으로서, 그
