Abstract

A dispenser includes a cam path and a mating guide pin to provide a closed position or an open position for the dispenser. The dispenser is selectively rotatable causing the mating guide pin to travel along a cam path to rotate between slanted, unslanted, and slanted downward positions. The mating guide pin in the cam path causes the open position to allow product delivery and causes the closed position to provide a seal to prevent product leakage. In an implementation, the dispenser is selectively guidable along a helical guide slot to an upward position for product application and to a downward position to retract the applicator. When the dispenser is selectively rotatable along the helical guide slot to a retracted position, the dispenser is in a stored state.

Claims

1. A cosmetic dispenser comprising:

a lower valve having a reservoir for containing a product, the lower valve having at least one aperture;

the dispenser being selectively guidable in a spiral motion between;

i) an upward position for the dispenser to apply the product, and

ii) a downward position to store the dispenser; and

an applicator coupled to the upper valve for applying the product.

2. The cosmetic dispenser of claim 1, further comprising the dispenser being selectively rotatable in a spiral motion with the at least one mating guiding pin and the at least one cam path between:

i) an open position for the dispenser to deliver the product; and

ii) a closed position to seal a delivery passageway.

3. The cosmetic dispenser of claim 1, further comprising the dispenser being selectively guidable in a helical motion along a helical guide slot between:

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

4. The cosmetic dispenser of claim 2, wherein a rotation of the dispenser to the open position causes the at least one aperture in upper valve to be alignable with the at least one aperture in the lower valve for product delivery;

and the rotation of the dispenser to the closed position causes the at least one raised section in the upper valve to be alignable with the at least one aperture in the lower valve to seal the delivery passageway.

5. The cosmetic dispenser of claim 1, further comprising a flow-through compressible gasket coupled to the lower valve and the upper valve, the dispenser being selectively guidable with the at least one mating guide pin and the at least one cam path between:

an upward slanted position, wherein the flow-through compressible gasket is selectively decompressed to allow for dispensing the product;

a downward slanted position, wherein the flow-through compressible gasket is selectively compressed to provide a seal for preventing the product from leaks; and

a flat unslanted position, wherein the flow-through compressible gasket is not compressed while the at least one aperture in the lower valve is selectively alignable with the at least one raised section in the upper valve.

6. The cosmetic dispenser of claim 1, further comprising a flow-through compressible gasket coupled to the lower valve and the upper valve, the flow-through compressible gasket comprises:

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

at least one aperture being located on the substantially disk-shaped body and being alignable with the at least one aperture of the lower valve and with the at least one aperture of the upper valve to define a delivery passageway for the product.

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

a first circular ring surrounding the at least one aperture on the bottom side of the substantially disk-shaped body;

a second circular ring surrounding the at least one aperture on the top side of the substantially disk-shaped body; and

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

8. The cosmetic dispenser of claim 1, further comprising a flow-through compressible gasket coupled to the lower valve and the upper valve, the flow-through compressible gasket made of a thermoplastic elastomer (TPE) material.

9. The cosmetic dispenser of claim 1, further comprising another mating guide pin located on the upper valve to travel against another cam path located on the lower valve.

10. The cosmetic dispenser of claim 1, further comprising another mating guide pin located on the upper valve at about 180 degrees to the at least one mating guiding pin to travel against another cam path located on the lower valve located at about 180 degrees to the at least one cam path.

11. The cosmetic dispenser of claim 1, wherein the spiral motion between the upward slanted and downward slanted positions comprises an actuation of at least about 10 degrees to at most about 300 degrees.

12. A cosmetic dispenser comprising:

a lower valve having a reservoir for containing a product, the lower valve having at least one aperture;

an upper valve coupled to the lower valve, the upper valve having at least one aperture and at least one raised section;

at least one mating guide pin located on the lower valve;

at least one cam path coupled to the at least one mating guide pin located on the upper valve;

the dispenser being selectively guidable in a spiral motion with the mating guide pin travelling along the cam path between;

i) an upward slanted position for the dispenser to be in an open state, wherein the at least one aperture in the lower value is selectively alignable with the at least one aperture in the upper valve, and

ii) a flat unslanted position for the dispenser to be in a closed state, wherein the at least one aperture in the lower valve is selectively alignable with the at least one raised section in the upper valve; and

an applicator coupled to the upper valve for applying the product.

13. The cosmetic dispenser of claim 12, further comprising the dispenser being selectively guidable in a helical motion along a helical guide slot between:

i) an upward position for the dispenser to apply the product, and

ii) a downward position to retract the dispenser.

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

an upper guide pin located on the upper valve and a lower guide pin located on the lower valve, the upper guide pin being selectively rotatable along a helical motion;

a flow-through compressible gasket coupled to the lower valve and the upper valve, the dispenser being selectively guidable along the cam path in the helical motion between;

the upward slanted position, wherein the flow-through compressible gasket is selectively decompressed to allow for dispensing the product;

a downward slanted position, wherein the flow-through compressible gasket is selectively compressed to provide a seal for preventing the product from leaks; and

the flat unslanted position, wherein the flow-through compressible gasket is not compressed, while the at least one aperture in the lower valve is selectively alignable with the at least one raised section in the upper valve.
