Description

Cosmetic pencil

Technical Field

The utility model belongs to the technical field of cosmetics and specifically relates to a cosmetic pencil.

Background

The existing cosmetic pen with the function of stretching the paste usually achieves the effect that the paste is stretched and driven by the stretching of the stretching rod through the fixation of the stretching rod and the paste, so that the designed cosmetic pen looks very convenient, but after the paste is used, the paste is difficult to be added again, and the added paste is difficult to be stably fixed with the stretching rod; the existing cosmetic pencil with the paste body and the inner push rod not fixed facilitates secondary adding of the paste body, but once the paste body is excessively extruded in use, the paste body is not recovered, and waste of the paste body is caused. Therefore, a cosmetic pencil is needed, which can solve the problem that the cosmetic pencil is difficult to add for the second time and can also solve the problem that the paste is difficult to withdraw after being extruded for a long time.

Chinese patent application publication No. CN108514208A, published as 09/11/2018, entitled "cosmetic pencil," discloses a cosmetic pencil, which includes a front pencil body, a front sealing member, a clip wheel member, a spherical rotating member, a pencil head sealing member, a pencil lead sealing member, an inner plug, a rear pencil body, and a push-pull assembly thereof, wherein the front pencil body and the rear pencil body are matched to form a pencil holder; the front sealing piece is arranged in the front end of the front pen body; the inner plug is embedded into the refill rod sealing piece from the upper end; the wheel clamping piece is arranged in the front end of the front pen body and is provided with a wheel clamping hole; the spherical rotating piece comprises a sealing sphere, a rotating gear and a rotating shaft thereof; the pen point sealing piece comprises a transmission rack and a rear sealing piece; the front end of the pen core rod sealing element is provided with a protruding rewinding convex point which is matched with the rewinding groove. This cosmetic pencil has ensured promptly that nib and refill material body can not dry through the all-round sealed to nib and refill material body, has also ensured the health of nib, can let the consumer realize one-hand operation moreover, simultaneously, has reduced the design of pen cap, has reduced manufacturing cost. However, this device does not take into account the problems of extrusion and secondary addition of the refill body, i.e., the paste.
