Plug-and-pull ball structure, a mascara tube and a lip gloss tube

Abstract

A plug-and-pull ball structure, mascara tube and lip gloss tube, which include outer cap, inner cap, ball and bottle body; outer cap is installed on the outside of inner cap, combination structure of inner cap and outer cap is fit to the body through a plug-and-pull mechanism; the ball is installed on inner cap. To plug in combination structure, outer cap will drive ball toward body, so ball interferes with body; to pull out combination structure, body will drive ball toward outer cap, so ball interferes with outer cap. Relied upon is the immovable structure including ball and body groove that is disposed between inner and outer cap combination. Instead of guaranteeing the airtightness of traditional cap-bottle combination through threaded connection, its bottle-cap combination does not have to rotate the thread, and the combination can be directly plugged and pulled without compromising the airtight effect.

Dependencies are inferred from the claim text.
