The present invention relates to an air conditioner comprising: a cylinder portion having a receiving portion with one surface opened and communicating with the receiving portion to form a discharge port, and a cap is coupled to the discharge port； A piston ring inserted in the receiving portion of the cylinder to seal the opened surface of the receiving portion to form a first space for accommodating the first material, and a piston ring slidably coupled to the inside of the piston ring A piston portion having a second space formed therein for receiving a second material therein and having a peak portion for cutting the separation membrane； And a spigot part which is coupled with the storage container of the piston part inserted into the cylinder part and protrudes outside the cylinder part and pressurizes and moves the storage container at the time of use, the storage container being moved by the pressing of the spigot part, Wherein the piston ring is cut out of the separation membrane and the second material contained therein is introduced into the first space of the cylinder part through the cut-off membrane to be mixed with the first material. According to the present invention, since the first material and the second material having different components in the cylindrical portion of the syringe are separated and accommodated with respect to the separation membrane, deterioration and oxidation due to mixing of different materials can be prevented, There is an effect that natural mixing of the first material and the second material can be facilitated.본 발명은 일면이 개방된 수용부가 형성되고 상기 수용부와 연통하여 배출구가 형성되며 상기 배출구에 캡이 결합되는 실린더부； 상기 실린더의 수용부에 삽입되어 수용부의 개방된 면을 밀폐시킴에 따라 제 1 물질을 수용하는 제 1 공간을 형성하게 되는 분리막이 구비된 피스톤링과, 상기 피스톤 링의 내부에 슬라이딩 가능하게 결합되고 내부에 제 2 물질을 수용하는 제 2 공간이 형성되며 상단에 상기 분리막의 절취를 위한 첨두부가 형성된 보관용기로 구성되는 피스톤부； 상기 실린더부 내에 삽입된 피스톤부의 보관용기와 결합되어 실린더부 외측으로 돌출되고 사용시 보관용기를 가압하여 이동시키는 밀대부；를 포함하고, 상기 보관용기는 상기 밀대부의 가압에 의해 이동되어 상단의 첨두부가 피스톤 링을 분리막을 절취하고 내부에 수용된 제 2 물질이 절취된 분리막을 통해
