technical field

The invention relates to the field of lipstick tubes, in particular to an improved structure of a bundle in a lipstick tube.

Background technique

The traditional lipstick tube uses the gap between the spiral and the fork to control the smooth rotation by rotating the spiral, so that the barrel moves upward along the guide groove on the inner wall of the spiral until the lipstick is pushed out of the fork port. In order to ensure the smooth rotation of the lipstick tube as a whole, oil is usually applied to the screw, but since there is a gap between the screw and the fork, the oil is easy to seep out from the gap after the oil is applied, polluting the surface of the product, and there will also be a phenomenon of string movement ; But when there is no gap between the two, there will be a squeaking sound, which will affect the user's use.
