Abstract

A cosmetic application device may include a housing having an opening on a top surface, an inner tube disposed within the housing, and a wheel actuator disposed on a side surface of the housing and rotatably coupled to the inner tube. The inner tube may be configured for holding a cosmetic product stick. Rotation of the wheel actuator may cause the cosmetic product stick to move axially through the housing and out of the opening.

First claim

What is claimed is:

1. A cosmetic application device comprising:
a housing having an opening on a top surface thereof;
an inner tube disposed within the housing and configured for holding a cosmetic stick;
a wheel actuator disposed on a side surface of the housing and rotatably coupled to the inner tube, the wheel actuator configured such that rotation of the wheel actuator causes the cosmetic stick to move axially through the housing and out of the opening;
a base insert having an upper recess configured to receive a lower portion of the inner tube, the base insert disposed within the housing and fixed against rotation relative to the housing; and
a product holder having a threaded shaft with a cup on an upper end thereof configured to receive a product stick.

2. The cosmetic application device of claim 1 , wherein rotation of the wheel actuator causes the inner tube to rotate within the housing without moving axially along the housing.

3. The cosmetic application device of claim 2 , wherein the wheel actuator includes a first gear and the inner tube includes a second gear mated with the first gear.

4. The cosmetic application device of claim 3 , wherein the first and second gears are bevel miter gears.

5. The cosmetic application device of claim 1 , wherein the base insert defines a channel at least an upper portion of which is threaded, the threading matching threading on the threaded shaft of the product holder such that rotation of the threaded shaft causes the threaded shaft to move axially relative to the base insert.

6. The cosmetic application device of claim 5 , wherein the threaded shaft of the product holder has a non-circular cross section taken transverse to a longitudinal axis thereof and the inner tube has a non-circular opening in a bottom face thereof, the non-circular opening sized and shaped to match the non-circular cross section of the threaded shaft such that when the non-circular threaded shaft is disposed through the non-circular opening, rotation of the inner tube causes rotation of the threaded shaft, wherein the cup of the product holder is disposed within the inner tube with the threaded shaft extending downward through the non-circular opening and into the channel of the base insert, wherein vertical rotation of the wheel actuator causes horizontal rotation of the inner tube relative to the housing and base insert, which rotates the threaded shaft of the product holder, rotation of the threaded shaft against the threading on the channel of the base insert causes the product holder to move axially relative to the housing, moving the product stick out of or back into the opening in the top surface of the housing.

7. The cosmetic application device of claim 6 , wherein the non-circular opening and non-circular cross section are rectangular.

8. The cosmetic application device of claim 1 , further comprising a product stick disposed within the housing, the product stick selected from the group consisting of lipstick, lip liner, lip balm, eyeliner, eye shadow, eyebrow pencil, concealer, foundation, blush, deodorant, and sunscreen.

9. The cosmetic application device of claim 1 , wherein the wheel actuator is positioned adjacent a lower end of the housing, opposite the top surface.

10. The cosmetic application device of claim 1 , wherein the wheel actuator is positioned closer to the top surface of the housing than to a lower end of the housing.

11. A cosmetic application device comprising:
a housing having an opening on a top surface thereof;
an inner tube disposed within the housing and configured for holding a cosmetic stick;
a wheel actuator disposed on a side surface of the housing and rotatably coupled to the inner tube, the wheel actuator configured such that rotation of the wheel actuator causes the cosmetic stick to move axially through the housing and out of the opening; and
a cap configured to be removably disposed over the top surface of the housing, the cap having a locking member configured to prevent the wheel actuator from being rotated when the cap is disposed on the housing.

12. The cosmetic application device of claim 11 , wherein the wheel actuator includes a plurality of grooves on a circumferential outer surface thereof and the locking member includes at least one extension configured to engage at least one of the plurality of grooves on the wheel actuator, thereby preventing the wheel actuator from being rotated when the cap is disposed on the housing.

13. The cosmetic application device of claim 11 , further comprising a base insert and product holder, the base insert disposed within the housing and fixed against rotation relative to the housing, the base insert having an upper recess configured to receive a lower portion of the inner tube, the product holder defining a threaded shaft with a cup on an upper end thereof configured to receive a product stick.

14. The cosmetic application device of claim 13 , wherein the base insert defines a channel at least an upper portion of which is threaded, the threading matching threading on the threaded shaft of the product holder such that rotation of the threaded shaft causes the threaded shaft to move axially relative to the base insert.

15. A device for dispensing and applying a cosmetic product, the device comprising:
a housing configured to hold a cosmetic product stick, the housing comprising an open top end and a passageway extending longitudinally from the open top end to a closed bottom end;
a base insert fixedly disposed within the passageway adjacent the closed bottom end, the base insert having a channel that is at least partially threaded;
a product holder having a threaded shaft rotatably disposed with in the channel of the base insert, the product holder having a cup configured to receive the cosmetic product stick;
an inner tube having a bottom end face disposed within an upper portion of the channel of the base insert, the inner tube rotatable relative to the base insert, the bottom end face having an opening configured to receive the threaded shaft of the product holder such that the threaded shaft of the product holder rotates with the inner tube; and
a wheel actuator rotatably connected to a side of the inner tube such that rotation of the wheel actuator causes rotation of the inner tube, thereby rotating the product holder and moving the product holder axially within the housing.

16. The device of claim 15 , wherein the inner tube includes a first gear rotatably engaged with a second gear on the wheel actuator.

17. The device of claim 16 , wherein the first gear is a bevel gear disposed circumferentially around an outer surface of the inner tube and the second gear is a bevel gear disposed within the wheel actuator.

18. The device of any claim 15 , further comprising a cap configured to be removably disposed over the open top end of the housing, the cap having a locking member configured to prevent the wheel actuator from being rotated when the cap is disposed on the housing.

19. The device of claim 18 , wherein the wheel actuator includes a plurality of grooves on a circumferential outer surface thereof and the locking member includes at least one extension configured to engage at least one of the plurality of grooves on the wheel actuator, thereby preventing the wheel actuator from being rotated when the cap is disposed on the housing.

20. The device of claim 15 , further comprising a product stick having a bottom end disposed within the cup of the product holder, the product stick moveable along the passag
