Abstract

A dispenser includes a housing having a reservoir for containing a product. The dispenser includes a flow-through gasket with a concave shape top having a plurality of apertures. The dispenser provides a product delivery passageway through the flow-through gasket when the dispenser is in an open position. The dispenser prevents leakage by providing a seal with the flow-through gasket when the dispenser is in a closed position. In some examples, the flow-through gasket with the concave shape top may be made of a material having elastomeric properties.

Claims

1. A cosmetic dispenser comprising:

a housing having a reservoir for containing a powdered cosmetic product;

the housing including a flow-through gasket with a plurality of apertures and a concave shape top;

an actuator coupled to the dispenser and the flow-through gasket, the actuator being selectively rotatable to an open position for the dispenser to deliver the powdered cosmetic product through the plurality of apertures in the flow-through gasket;

the actuator being selectively rotatable to a closed position for the dispenser to prevent leakage of the powdered cosmetic product by creating a seal with the plurality of apertures in the flow-through gasket; and

an applicator coupled to the concave shape top of the flow-through gasket for applying the powdered cosmetic product.

2. The cosmetic dispenser of claim 1, wherein the flow-through gasket comprises a thermoplastic elastomer (TPE) material.

3. The cosmetic dispenser of claim 1, wherein the apertures in the flow-through gasket are substantially circular-shaped, substantially square-shaped, or substantially oval-shaped.

4. The cosmetic dispenser of claim 1, wherein the flow-through gasket comprises a substantially disk-shaped body with a raised center section on a bottom side.

5. The cosmetic dispenser of claim 4, wherein the flow-through gasket further comprises an elongated stem disposed between and formed integrally with the concave shape top and the disk-shaped body.

6. The cosmetic dispenser of claim 4, wherein the flow-through gasket comprises:

the plurality of apertures being located on the bottom side of the substantially disk-shaped body;

a circular ring surrounding the plurality of apertures on the bottom side of the substantially disk-shaped body;

an outer perimeter comprising a plurality of flat sides and a plurality of semicircular sides, alternating on the substantially disk-shaped body, the plurality of semicircular sides to hold the flow-through gasket in place to the actuator when rotation occurs; and

the plurality of apertures terminates in a base of the concave shape top.

7. The cosmetic dispenser of claim 1, wherein the concave shape top in the flow-through gasket comprises a depth of at least about 15 mm and a width of at least about 30 mm.

8. The cosmetic dispenser of claim 1, wherein the concave top in the flow-through gasket is substantially circular-shaped, substantially square-shaped, or substantially oval-shaped.

9. The cosmetic dispenser of claim 1, wherein the actuator being selectively rotatable to an open position comprises the plurality of apertures in the flow-through gasket being alignable with a plurality of apertures in an inner dial to define a delivery passageway for the powdered cosmetic product.

10. The cosmetic dispenser of claim 1, wherein the actuator being selectively rotatable to a closed position for the dispenser comprises the plurality of apertures in the flow-through gasket being alignable with a plurality of raised sections in an inner dial to define a seal to prevent leakage of the powdered cosmetic product.

11. The cosmetic dispenser of claim 1, wherein a rotation mechanism comprises a rotation of least about 10 degrees to at most about 359 degrees.

12. The cosmetic dispenser of claim 1, further comprising an o-ring seal located between the reservoir and an inner dial.

13. The cosmetic dispenser of claim 1, wherein the applicator comprises a sponge or a powder puff.

14. A dispenser comprising:

a housing having a reservoir for containing a product;

an actuator coupled to the housing, the actuator being selectively rotatable to an open position for the dispenser and the actuator being selectively rotatable to a closed position for the dispenser;

a flow-through gasket having a plurality of apertures and a concave shape top interposed between the housing and the actuator;

an applicator coupled to the concave shape top of the flow-through gasket for applying the product.

15. The dispenser of claim 14 wherein the flow-through gasket comprises a thermoplastic elastomer (TPE) material and the apertures in the flow-through gasket are substantially circular-shaped, substantially square-shaped, or substantially oval-shaped.

16. The dispenser of claim 14, wherein the flow-through gasket comprises:

a substantially disk-shaped body with a raised center section on a bottom side; and

an elongated stem disposed between and formed integrally with the concave shape top and the disk-shaped body.

17. The dispenser of claim 16, wherein the flow-through gasket comprises:

the plurality of apertures being located on the bottom side of the substantially disk-shaped body; and

a circular ring surrounding the plurality of apertures on the bottom side of the substantially disk-shaped body.

18. The dispenser of claim 16, wherein the flow-through gasket comprises:

an outer perimeter comprising a plurality of flat sides and a plurality of semicircular sides, alternating on the substantially disk-shaped body; and

the plurality of apertures terminates in a base of the concave shape top.

19. The dispenser of claim 14, wherein the concave shape top in the flow-through gasket comprises a depth of at least about 15 mm and a width of at least about 30 mm.

20. The dispenser of claim 14, wherein the concave top in the flow-through gasket comprises a depth of at least about 10 mm to at most about 20 mm and a width of at least about 20 mm to at most about 50 mm, and the concave top provides a temporary place for storing the product.

21. A flow-through gasket comprising:

a substantially disk-shaped body with a top side and a bottom raised center section on a bottom side;

a concave shape top on the top side of the substantially disk-shaped body;

a plurality of apertures being located on the substantially disk-shaped body; and

a circular ring surrounding the plurality of apertures on the bottom side of the substantially disk-shaped body.

22. The flow-through gasket of claim 21, further comprising an outer perimeter comprising a plurality of flat sides and a plurality of semicircular sides, alternating, on the substantially disk-shaped body.

23. The flow-through gasket of claim 21, wherein the flow-through gasket further comprises an elongated stem disposed between and formed integrally with the concave shape top and the disk-shaped body.

24. The flow-through gasket of claim 21, wherein the plurality of apertures located on the disk-shaped body comprises at least three apertures arranged at a triangle configuration.

25. The flow-through gasket of claim 21, wherein the apertures in the flow-through gasket are substantially circular-shaped and at least about 2 mm in size.

26. The flow-through gasket of claim 21, wherein the concave shape top is substantially circular-shaped, substantially square-shaped, or substantially oval-shaped.
