Abstract

A button type lip gloss tube comprising a liquid storage tube and a lip gloss brush mounted on the liquid storage tube. The lip gloss brush comprises a cap, a rod core movably mounted in the cap, a spring pressed between the cap and the rod core, and a button ring mounted in the cap. The button ring comprises a button and an elastic ring. The elastic ring confines the liquid storage tube, which is inserted into the cap, between the rod core and the elastic ring. When the button is pressed, the elastic ring is deformed and the liquid storage tube is disengaged from the cap by an elastic force of the spring. The button type lip gloss tube is convenient to install, highly automatic in production and assembly, and is convenient for a user to use since the lip gloss tube is opened by pressing the button.

First claim
