Double-ended cosmetic applicator

Abstract

This utility model relates to a double-ended makeup contour stick, addressing the technical problem that existing similar products rarely adopt a double-ended structure design that combines lipstick or other cream-based products, resulting in a large volume, especially due to the shortcomings of the spiral structure design. The contour stick has a sponge for contouring at one end and a contouring paste at the other end. The key feature is that a middle section is fixed at the opening of one end of the pen body. A tip extends out of and engages with the inner diameter of the opening at that end of the middle section. Rotation of the tip causes a bead inside the tip to rotate, simultaneously causing the bead to extend and retract, and the paste on the bead to extend or retract into the tip. A threaded ring is fixed to the inner wall of the middle section below the tip. The threaded section of the other end of the bead in the middle section below the tip connects to the inner thread of the threaded ring. The bead moves up and down within the threaded ring by rotation, causing the bead to change position within the tip and the middle section.

Description

Technical Field

[0001] This utility model relates to a makeup contouring pen with a sponge tip, which is a double-ended makeup contouring stick. Background Technology

[0002] There are currently some cosmetic tubes or contour sticks with sponge tips (functional tips). Contouring sticks are cosmetics that can be used on the face and lips. Their structure and usage are similar to lipstick tubes and other cosmetics. Some contouring products use liquid in their contour bottles, such as application number 202420602434.8 disclosed in Chinese patent literature, authorized on November 29, 2024, with the utility model name "A Contouring Bottle"; other contour sticks are used for applying solid or powder products and have a double-ended structure with a sponge tip and a brush head, such as application number 202220157870.X disclosed in Chinese patent literature, authorized on August 26, 2022, with the utility model name "A Novel Multifunctional Contouring Cosmetic Packaging Material". Lipstick tubes are used for solid lipsticks and are usually designed with a twist-up mechanism. The lipstick is fixed inside the tube, and the bottom is twisted to push out the lipstick. They are mostly cylindrical or square tubes, with the cap directly snapped onto the tube. However, the aforementioned products and existing similar makeup and grooming tools with sponge tips (functional tips) rarely adopt a dual-head design that combines lipstick or other lipstick-like products. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a double-ended makeup contouring stick, thereby solving the technical problems of existing similar makeup contouring tools with sponge tips (functional tips) rarely adopting a double-ended structure design that combines lipstick or other balm-like products, resulting in a relatively large volume in the structural design, especially the lack of a proper spiral structure design.
