Abstract

A dispenser includes a flow-through gasket and a lower valve having a reservoir for containing a product. The flow-through gasket has at least aperture to provide a product delivery passage when the dispenser is selectively rotatable along a helical guide slot to a raised position. When the dispenser is selectively rotatable along the helical guide slot to a retracted position, the dispenser is in a stored state. In some examples, the flow-through gasket may be made of a material having elastomeric properties.

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

4. The cosmetic dispenser of claim 1, wherein the at least one aperture in the flow-through gasket comprises a substantially circular-shape, a substantially square-shape, or a substantially oval-shape.

5. The cosmetic dispenser of claim 1, wherein the upper valve comprises at least one pipe for product delivery.

6. The cosmetic dispenser of claim 1, wherein the reservoir comprises a refillable bottle, such that the refillable bottle is removable to refill the bottle with product.

7. The cosmetic dispenser of claim 1, wherein the spiral rotation between the upward and downward positions comprises an actuation of at least about 15 degrees to at most about 300 degrees.

8. The cosmetic dispenser of claim 1, wherein the flow-through gasket moves vertically between the upper valve and the lower valve during rotation in the spiral motion between upward and downward positions.

9. The cosmetic dispenser of claim 1, wherein the flow-through gasket rotates as the lower valve is rotated during rotation in the spiral motion between upward and downward positions.

10. The cosmetic dispenser of claim 1, wherein rotation in the spiral motion to an upward position comprises the applicator being raised relative to the upper valve to deliver the product.

11. The cosmetic dispenser of claim 1, wherein rotation in the spiral motion to a downward position comprises the applicator being retractable for ease of storage.

12. The cosmetic dispenser of claim 1, further comprising:

a helical guide slot located on a collar of the dispenser; and

an upper guide pin located on the upper valve and a lower guide pin on the lower valve, the upper and lower guide pins being movable along the helical guide slot.

13. The cosmetic dispenser of claim 12, wherein the cosmetic dispenser is configured such that a rotation of the collar causes the upper and lower guide pins to move along the helical guide slot causing the upper valve, the flow-through gasket, and the lower valve to move between:

i) an upward position along the helical guide slot for the dispenser to deliver the product, and

ii) a downward position along the helical guide slot to store the dispenser.

14. A dispenser comprising:

a lower valve having a reservoir for containing a product;

an upper valve coupled to the lower valve, the upper valve and the lower valve being moveable between a raised position and a retracted position relative to each other;

an applicator coupled to the upper valve for applying the product; and

a flow-through gasket interposed between the lower valve and the upper valve, the flow-through gasket comprising at least one aperture and comprising an elastomer material, wherein moving the upper valve and the lower valve to the retracted position compresses the flow-through gasket between the upper valve and the lower valve.

15. The dispenser of claim 14, wherein the raised position defines a use position to deliver product and the retracted position defines a non-use position to store the dispenser.

16. The dispenser of claim 14, wherein in the raised position, the at least one aperture in the upper valve aligns with at least one aperture in the flow-through gasket and with at least one aperture in the lower valve to create a delivery passageway, and

wherein in the retracted position, the at least one aperture in the upper valve does not align with at least one aperture in the flow-through gasket and with at least one aperture in the lower valve, such that the delivery passageway is closed to prevent product leakage.

17. The dispenser of claim 14, further comprising a spiral motion between the raised and retracted positions.

18. The dispenser of claim 14, further comprising:

a helical guide slot located on a collar of the dispenser;

an L-shaped configuration located on a sleeve covered by the collar; and
