Technical Field

The utility model relates to the technical field of cosmetics, in particular to a cosmetic pen.

Background

Eyeliners are common cosmetics in daily life and are used for decorating eyeliners and improving the aesthetic degree of eyes. The existing eyeliners are generally divided into two types, namely solid eyeliners and liquid eyeliners, wherein the liquid eyeliners can play a better role in decoration by adding decoration powder into eyeliners compared with the solid eyeliners, such as pearlescent eyeliners, so that the liquid eyeliners are popular with beauty lovers.

The existing liquid eyeliner such as a pearly-lustre eyeliner generally comprises a penholder, a water-guiding core, a pen point type brush head and a pen cover. Wherein the penholder is internally provided with a containing cavity for containing the eyeliner liquid, the brush head is arranged at the liquid outlet end of the containing cavity, and the water diversion core is used for guiding the eyeliner liquid in the containing cavity to the brush head, so that the brush head can be used for drawing the eyeliner; after the makeup is finished, the pen cap is covered on the pen holder so as to seal the brush head in the pen cap and avoid air drying.

Although the water-leading core of the existing pearlescent eyeliner can play a role of draining the eyeliner, the eyeliner in the cavity is easy to leak from the brush head through the water-leading core in the transportation process of the eyeliner, which causes the waste of the eyeliner and influences the sale and normal use of the eyeliner.
