Airless type cosmetics vessel
摘要:
An airless type cosmetics vessel, in which, in order to suck a gel type cosmetic from a vessel body into a cylinder chamber, an axial valve primarily opens an inlet passage and closes an outlet passage according to stepwise upward movement of a piston and an axial valve, and the piston is further moved upwards, thus sucking the cosmetic into the cylinder chamber, and, in order to discharge the cosmetic from the cylinder chamber, the axial valve is primarily moved downwards so as to close the inlet passage and open the outlet passage, and the piston is further moved downwards, thus compressing the cosmetic in the cylinder chamber and discharging the cosmetic from the chamber, so that a precise cosmetic suction and discharge operation can be executed by the stepwise suction and discharge actions of the axial valve and the piston, separately provided, without malfunctioning.
