Abstract

Illustrative applicators include a roller controllably coupled to a reservoir by a wicking agent such as a felt applicator insert. A cap for the applicator is also provided. The action of the cap being placed over the roller brings the roller into contact with the wicking agent, applying product contained in the reservoir to the roller. Removing the cap causes the roller to move out of contact with the wicking agent, allowing a quantity of product applied to the roller while the cap is on the applicator to be used.

First claim

The claimed invention is:

1. An applicator for a cosmetic product comprising:
a cap; and
a body, the body comprising:
a roller;
an applicator insert to hold the roller;
a collar configured for mating with the cap;
a spring coupling the applicator insert to the collar;
a portion for holding product; and
a wicking agent;

wherein the roller, applicator insert, collar, spring, portion for holding product, and wicking agent are sized and configured to define:
a first configuration when the cap is applied and engaged to the collar in which the spring is in a compressed state such that the applicator insert is moved to a first juxtaposition and the roller is brought adjacent to or in contact with the wicking agent to deliver product to the roller; and
a second configuration when the cap is not applied in which the spring is in an extended state such that the applicator insert is moved to a second juxtaposition and the roller is separated from the wicking agent.

2. The applicator of claim 1 wherein, in the second configuration, the roller being separated from the wicking agent limits a quantity of product that may be applied without replacing the cap and effecting the first configuration.

3. The applicator of claim 1 , wherein the roller is a ball.

4. The applicator of claim 3 , wherein the applicator insert includes a recess configured to receive the ball, and a ridge configured to retain the ball within the recess, the recess and ridge configured to retain the ball while allowing the ball to rotate freely.

5. The applicator of claim 1 , wherein the roller is a wheel.

6. The applicator of claim 5 , wherein the applicator insert includes a slot configured to receive the wheel, and a pin configured to retain the wheel within the slot while allowing the wheel to rotate freely.

7. An applicator for a cosmetic product comprising:
a reservoir for holding the cosmetic product;
a collar disposed with an opening of the reservoir;
a spring disposed within the collar;
an applicator insert having a first end disposed within the spring and extending into the collar;
a roller movably fixed to a second end of the applicator insert;
an elongate wicking agent disposed within the reservoir and extending through the collar, the spring, and into the applicator insert; and
a cap configured for mating with the collar, wherein the reservoir, collar, spring, applicator insert, roller, wicking agent, and cap are configured such that:
when the cap is engaged with the collar, the cap moves the applicator insert toward the reservoir, thereby compressing the spring and moving the roller into contact with the wicking agent, allowing the cosmetic product to move from the reservoir, through the wicking agent, and into contact with the roller; and
when the cap is removed from the collar, the spring relaxes into an extended position, moving the applicator insert away from the reservoir and moving the roller out of contact with the wicking agent.

8. The applicator of claim 7 , wherein the roller is configured to dispense a limited amount of the cosmetic product as the roller is moved against a surface, wherein the limited amount is limited to product in contact with the roller when the cap was removed.

9. The applicator of claim 8 , wherein the roller is configured to receive an additional amount of cosmetic product when the cap is engaged with the collar, moving the roller into contact with the wicking agent.

10. The applicator of claim 7 , wherein the cap has internal ridges that engage ridges on the applicator insert.

11. The applicator of claim 7 , wherein the wicking agent is fixed relative to the reservoir.

12. The applicator of claim 7 , wherein the roller is a ball.

13. The applicator of claim 7 , wherein the roller is a wheel.

14. The applicator of claim 7 , wherein the roller is absorbent.

15. The applicator of claim 7 , wherein the roller is non-absorbent.

16. The applicator of claim 7 , wherein the roller includes one or more dimples in a surface thereof.

17. The applicator of claim 7 , wherein the roller includes a flocking material on a surface thereof.

18. A method of applying a cosmetic product, comprising:
loading cosmetic product onto a roller by placing a cap onto a collar of a cosmetic container thereby engaging the roller with a wicking agent, the cosmetic container including:
a reservoir for holding the cosmetic product;
the collar disposed with an opening of the reservoir;
a spring disposed within the collar;
an applicator insert having a first end disposed within the spring and extending into the collar;
the roller movably fixed to a second end of the applicator insert;
the wicking agent disposed within the reservoir and extending through the collar, the spring, and into the applicator insert; and
the cap configured for mating with the collar;

removing the cap thereby limiting an amount of the cosmetic product loaded onto the roller; and
dispensing the limited amount of cosmetic product by rolling the roller onto a user's skin.

19. The method of claim 18 , wherein dispensing the limited amount of cosmetic product includes rolling the roller onto skin until the limited amount of product is dispensed, the method further comprising replacing the cap onto the collar to load a second amount of product onto the roller.

20. The method of claim 19 , wherein after replacing the cap, the method further comprises removing the cap and dispensing the second amount of product.
