Abstract

A cosmetic device includes a barrel, a first transmission unit, a dispensing unit, a cover and a second transmission unit. The first transmission unit is co-rotated with the collar by rotating the mounting member to move the piston downward. The cosmetic liquid in the first room in the barrel flows out from the outlet of the dispensing unit. The mounting member is rotatable in one direction relative to the barrel by the engagement of the ratchet teeth portion of the collar and the pawl of the barrel. The reception tube of the second transmission unit is rotated to co-rotate the collar to let the rod spirally move in the inner tube to protrude the lipstick.

Claims

1. A cosmetic device comprising:

a barrel having a first room defined in a first end thereof, a second room defined in a second end of the barrel, the first room adapted to receive cosmetic liquid, an outer tube mounted to the second room and having a connection section extending from a lower end thereof;

a first transmission unit connected with the first room and having a first collar located in a mounting member, a threaded rod and a piston, the mounting member rotatably mounted to the first end of the barrel and having a first connection portion on an outside thereof, the first collar to one end of the threaded rod and the piston threadedly connected to the other end of the threaded rod, a first path defined centrally through the threaded rod;

a dispensing unit having a sleeve, a shaft and an applicator, the sleeve having an end thereof connected to the mounting member and at least one outlet defined in a lower end thereof, a second path defined centrally through the shaft, the shaft having an end movably inserted in the sleeve;

a first cover having multiple ridges extending from an inside thereof and a locking portion defined in the first cover, the ridges engaged with the first connection portion to secure the first cover to the mounting member, the locking portion of the first cover locked on an outside of the shaft;

a second transmission unit located in the outer tube and having an inner tube, a second collar, a rod and a reception tube, the inner tube having a threaded portion in a center thereof and a first end of the inner tube connected to the connection section, the second collar having multiple rails in a central passage thereof and rotatably mounted to the inner tube, the rod having two guide blocks on a first end thereof and a middle section of the rod having multiple guide slots which are located corresponding to the rails, the guide blocks threadedly connected to the threaded portion and the rails linearly mounted to the guide slots, a second end of the rod having a lipstick received therein, the reception tube mounted to the second collar, a second cover mounted to the outer tube.

2. The device as claimed in claim 1, wherein the mounting member has a toothed portion defined in an inside of a middle section thereof, the first collar has outer teeth which are engaged with the toothed portion to restrict the first collar in the mounting member.

3. The device as claimed in claim 2, wherein the barrel has a pawl connected to the first end thereof and the first collar has a ratchet teeth portion located in opposite to the outer teeth, the ratchet teeth portion is engaged with the pawl to restrict the first collar to rotation in one direction relative to the barrel.

4. The device as claimed in claim 1, wherein the sleeve has a protrusion extending from a lower end thereof and the protrusion is engaged with one end of the second path.

5. The device as claimed in claim 1, wherein the applicator is a brush or a sponge.

6. The device as claimed in claim 1, wherein the sleeve has an outward lip on a top end thereof and the shaft has an annular protrusion extending from a middle section thereof, the annular protrusion has an inward lip which contacts the outward lip to prevent the shaft from being pulled out.

7. The device as claimed in claim 1, wherein the inner tube has an annular groove defined in an outside of a second end thereof, the second collar has a convex portion which is engaged with the annular groove.

8. The device as claimed in claim 1, wherein the second collar has two slits defined therein and equally spaced apart from each other, the rails are equally spaced apart from each other.

9. The device as claimed in claim 1, wherein the rod has multiple ribs located axially on an inside of a second end thereof and the ribs are inserted into outside of the lipstick.

10. The device as claimed in claim 1, wherein the outer tube has a second connection portion and the second cover has a third connection portion defined in an inside thereof, the second and third connection portions are connected with each other.
