Cosmetic pen with continuously discharging mechanism

Abstract

A cosmetic pen with continuously discharging mechanism comprises: an elongate body with a pen head coupled at one end thereof. The elongate body comprises a material-pushing assembly, a driving assembly, a material bin and a check valve; the material-pushing assembly includes a central shaft coupled to the driving assembly at one end, and a spiral blade attached thereto at the other end; when the spiral shaft is driven by the driving assembly, material stored within the material bin is extruded by the spiral motion of the spiral blade toward the pen head so as to provide a steady supply of material to the pen head to facilitate smooth and continuously deployment of the material through the pen head; and the amount of released cosmetic material is controlled by controlling rotation number of the spiral blade, thus preventing waste.
