Document Type and Number:
WIPO Patent Application WO/2021/082179
Kind Code:
A1
Abstract:
The present invention relates to a bidirectional rotation lipstick tube. Two oppositely provided protruding ends are disposed on the outer circumference of a lower end of a lipstick paste support, and a rack is disposed on an inner side of a protruding end. A sleeve assembly comprises a sleeve, the sleeve is a circular tube that is slanted at an upper end, and a rotary shaft that passes through the center of the sleeve and has two ends mounted on a side wall of the sleeve is disposed at a lower part of the sleeve. A sector gear used in cooperation with the rack is fixedly connected to the middle part of the rotary shaft, and a small bevel gear is fixedly connected to one end of the rotary shaft at the interior of the sleeve. A rotary base assembly comprises a base, the base has a hollow design, a cylindrical protrusion is disposed at a bottom part, and a large bevel gear is fixedly connected to an upper end of the cylindrical protrusion. In the lipstick tube of the present invention, by continuously rotating the base in any direction, lipstick paste is reciprocatingly moved up and down, the reliability of the lipstick tube is improved, and the service life is prolonged. When the base rotates at a relatively small angle, one instance of lifting can be implemented for the lipstick, thus efficiency is increased and operation is easier.
