PURPOSE: A nozzle opening/closing apparatus of an airless type cosmetic container is provided to be able to prevent malfunction and to be able to perform an accurate opening/closing operation by opening/closing a discharge hole of a nozzle while moving forward and backward in the cam method. CONSTITUTION: A nozzle opening/closing apparatus of an airless type cosmetic container comprises a pumping tool, a nozzle housing (30), and a nozzle operation button (60). The nozzle operation button is installed between a stem of the pumping tool and the nozzle housing. A first operation spring (62) installed in the upper part of the nozzle operation button elastically supports the nozzle housing. A cam guide operation unit (65) is formed on one upper side of the nozzle operation button. A guide groove unit (46) formed in the rear part of a plunger (45) of the opening/closing nozzle is guided upward and downward along the cam guide operation unit by pressurization of the button, and moves the plunger forward and backward of a nozzle tube by the cam operation to open/close the nozzle. |
