Double pencil mixing and discharging structure for makeup pencil

The present invention is a double-tube mixing and stirring discharging structure of a pencil, which is filled with different cosmetic materials through separate filling container cavities, and then a stirring core is arranged in the discharging port for mixing and discharging to achieve mixing and discharging. For the purpose of makeup.

The traditional makeup pen structure is usually a cavity filled with a single cosmetic material, and the cosmetic material is pre-mixed and filled in the cavity, and the material is pressed and extruded by the pressing mechanism of the top cover of the cosmetic pen for the consumer to make up. Use; however, in order to meet the needs of different cosmetic applications, for some special cosmetic materials, if they are mixed before being filled, after storage for a period of time, it is very likely that due to the characteristics of different chemical materials, There will be doubts about chemical changes or deterioration of the cosmetic materials after mixing; especially for cosmetics from the factory to the consumer, there will be a considerable time difference, for special cosmetic materials, may not be set according to their original use. The demand is easy to produce a situation in which the cosmetic quality or the bluntness is unsatisfactory, so that the output of the pen is mixed and designed.

The present inventors have provided a double-tube mixing and agitating discharge structure of a cosmetic pencil in view of the defects of the conventional stylus using materials, and have different independent cavities, and two different cosmetic materials are filled. When filling separately, mixing is used when discharging, effectively ensuring that different cosmetic materials maintain their own special Sexuality, to overcome the lack of stability of storage and release of traditional materials, to meet consumer demand for cosmetic use and safe maintenance.

The main purpose of this creation is to fill the separate cosmetic materials through the independent packaging container cavity, and then set the stirring core in the discharge port, and the stirring core guides the stirring to achieve the extrusion of the cosmetic material. The mixing core of the tube is stirred and mixed synchronously, and the utility model and the utility model have the functions and purposes of safe storage and use of the cosmetic material for safe storage and makeup.
