## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a container, and more particularly to a composite cosmetic container that is capable of containing multiple cosmetic products and is easy to operate.
2. Description of Related Art
A conventional cosmetic container has a first rotating tube, a second rotating tube, a seat and a vessel. The first rotating tube has an inner surface and two longitudinal grooves formed in the inner surface of the first rotating tube. The second rotating tube is rotatably mounted around the first rotating tube. The second rotating tube has an outer surface and two guide chutes formed through the outer surface of the second rotating tube. The seat has a body and two protrusions. The protrusions are mounted on an outer surface of the body. The protrusions are inserted into the longitudinal grooves and the guide chutes respectively. The vessel is mounted on the body. The vessel has a chamber and an outlet. The chamber is formed in the vessel to contain a cosmetic product. The outlet is formed in the vessel and is in communication with the chamber.
Users can rotate the first rotating tube, and then the first rotating tube is rotated with the second rotating tube. The protrusions of the seat are moved along the longitudinal grooves of the first rotating tube and the guide chutes of the second rotating tube, and then the seat drives the vessel to move upward or downward. When the vessel moves upward, the outlet of the vessel extends out, and the cosmetic product in the body can be dispensed easily.
The relative rotation between the first rotating tube and the second rotating tube can only drive a single vessel to move upward or downward, and the vessel only contains one cosmetic product. Therefore, the cosmetic container is not versatile in use.
To overcome the shortcomings, the present invention tends to provide a composite cosmetic container to mitigate or obviate the aforementioned problems.

The caps 53 of the vessels 50 mounted in the first seat 30 and the second seat 30a are retracted into the second rotating tube 40. As the first sleeve 10 keeps rotating in the anticlockwise rotation, the guide element 31 of the first seat 30 moves to the distal end of the second transverse section 26 of the first chute 22. In the meanwhile, the guide element 31 of the second seat 30a moves from the bottom end of the slanting section 24 of the second chute 22a to the first transverse section 25 of the second chute 22a, and the second seat 30a moves upward along a corresponding one of the longitudinal grooves 42 of the second rotating tube 40. Therefore, the outlet 55 of the vessel 50 mounted in the second seat 30a is exposed out of the second sleeve 60. The outlet 55 of the vessel 50 mounted in the first seat 30 is hidden in the second sleeve 60.
The composite cosmetic container has multiple vessels 50 to contain multiple cosmetic products, such as lotions or perfumes. Users can rotate the first sleeve 10 to select one of the vessels 50 to move upward for conveniently dispensing the cosmetic product contained in the selected vessel 50. In addition, the outer diameter of the body 51 is smaller than the diameter of the through hole 45. Therefore, the vessels 50 are easy to be changed for replacement.
Accordingly, the composite cosmetic container has multiple vessels 50 to contain multiple cosmetic products, so the options of the cosmetic products stored therein are increased. Besides, the composite cosmetic container facilitates easy control of the vessels 50 to selectively move upward or downward by the relative rotation between the first sleeve 10 and the second sleeve 60.
