Description

Special-shaped aluminum lipstick tube and forming die thereof

Technical Field

The utility model belongs to the technical field of aluminium system package material, concretely relates to abnormal shape aluminium system lipstick tube and forming die thereof.

Background

At present, makeup is an indispensable part of daily life of many people, and can significantly improve the image and confidence, and the form of the makeup is various, such as powder, liquid, paste, and the like. In order to facilitate the use of the cosmetic product, the skilled person will generally make different cosmetic products into different shapes and put them in suitable containers, wherein the cosmetic product in the form of a stick, such as a lipstick, a concealer, a skin whitening stick or a sunscreen stick, is generally put in a tube, and such a tube is generally called a lipstick tube. The common lipstick tube in the market comprises a cover, a tube body, a rotary base and a middle bundle core in the tube body, wherein the paste is on the middle bundle core; the working principle of the paste extractor is that the up-and-down movement of the middle bundle core in the tank body is basically realized by rotating the base, so that the paste is extended out of the pipe body or retracted into the pipe body.

In order to increase the diversity of lipstick tube products, technicians make a lot of apparent improvements on the tube body and the cover of the lipstick tube, for example, various patterns, uneven structures and the like are formed on the surface of the tube body and the cover, so that in order to facilitate forming and reduce the manufacturing cost of products, the tube body and the cover of the existing common lipstick tube are made of hard plastics, and in order to further improve the grade of the lipstick tube, the metal texture of the lipstick tube is a great trend in the market.
