Abstract
A nozzle opening/shutting device of an airless type cosmetics vessel, in which a nozzle actuation button is installed between a nozzle housing and a stem, and a cam guide actuation unit is provided such that the cam guide actuation unit can guide a guide groove of a plunger upward and downward and can move the plunger forward and backward in a nozzle pipe by a cam operation, thereby opening and shutting the nozzle. This invention can move the plunger by a cam mechanism instead of a conventional spring mechanism, thereby preventing a misoperation and realizing a precise nozzle opening/shutting operation. The plunger is inserted in the nozzle such that a plunger end protrudes outside the nozzle and comes into close surface contact with the inlet of the nozzle, thereby preventing air introduction into the nozzle and preventing oxidation of the contents, and maintaining the quality of the contents constantly.
