Abstract

A cosmetic container has a first sleeve, a driving assembly, a bottle and a second sleeve. The driving assembly is mounted in the first sleeve and has a first rotating tube, a seat and a second rotating tube. The seat is moveably mounted in the first rotating tube. The second rotating tube is rotatably mounted around the first rotating tube. The bottle is mounted in the seat of the driving assembly and has a vacuum valve and an outlet. The second sleeve is coactively mounted on the second rotating tube. The first sleeve is rotated by the driving assembly to drive the bottle to move up and down. Therefore, the cosmetic container can be operated conveniently. The piston can push out the cosmetic product in the body effectively. Therefore, quantity of cosmetic product remaining on an inner surface of the body is decreased.

Claims

1. A cosmetic container comprising:

a first sleeve;

a driving assembly mounted in the first sleeve and having

a first rotating tube coactively mounted in the first sleeve and having

an outer surface;

an inner surface;

an annular flange formed on the outer surface of the first rotating tube;

multiple chutes formed through the outer surface of the first rotating tube and each chute having

a slanting section; and

a transverse section connected to a top end of the slanting section; and

multiple ribs formed on the inner surface of the first rotating tube;

a seat moveably mounted in the first rotating tube and having

an outer surface;

multiple protrusions respectively protruding into the chutes of the first rotating tube; and

multiple positioning members mounted on the outer surface of the seat and respectively connected to the ribs of the first rotating tube; and

a second rotating tube rotatably mounted around the first rotating tube and having

an inner surface;

an annular groove formed in the inner surface of the second rotating tube and connected to the annular flange of the first rotating tube;

multiple longitudinal grooves formed in the inner surface of the second rotating tube and the protrusions of the seat respectively protruding into the longitudinal grooves; and

a positioning ring formed on the inner surface of the second rotating tube and an internal diameter of the positioning ring being smaller than an internal diameter of the second rotating tube, and the positioning ring having

a positioning surface formed on a top surface of the positioning ring;

a bottle mounted in the seat of the driving assembly and having

a body mounted in the seat of the driving assembly and an outer diameter of the body being smaller than the internal diameter of the positioning ring;

a chamber formed in the body;

a piston mounted in the body and moveably located in the chamber;

a vacuum valve mounted on the body;

a cap mounted on the vacuum valve and a bottom surface of the cap facing the positioning surface of the positioning ring; and

an outlet formed in the cap and sunk in the second rotating tube; and

a second sleeve coactively mounted on the second rotating tube of the driving assembly.

3. The cosmetic container as claimed in claim 1, wherein

the bottle has

a mark mounted on a top surface of the cap to indicate the outlet of the bottle.

5. The cosmetic container as claimed in claim 1, wherein one of the chutes of the first rotating tube has a longitudinal section connected to the transverse section of said chute.

7. The cosmetic container as claimed in claim 3, wherein one of the chutes of the first rotating tube has a longitudinal section connected to the transverse section of said chute.

9. The cosmetic container as claimed in claim 1, wherein

the bottle has

a recess formed in an outer surface of the cap and located below the outlet.

11. The cosmetic container as claimed in claim 3, wherein

the bottle has

a recess formed in an outer surface of the cap and located below the outlet.

13. The cosmetic container as claimed in claim 5, wherein

the bottle has

a recess formed in an outer surface of the cap and located below the outlet.

15. The cosmetic container as claimed in claim 7, wherein

the bottle has

a recess formed in an outer surface of the cap and located below the outlet.
