Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] Embodiments of the invention described herein pertain to the field of personal care. More particularly, but not by way of limitation, one or more embodiments of the invention enable an adjustable dual chamber spraying device.

[0003] 2. Description of the Related Art

[0004] Spraying devices for the application of solutions onto human skin are known in the art. Such devices may be used to apply medicines, treatments, cosmetics, and other formulas. For example, such spraying devices may be used in sunless tanning applications. Sunless tanning allows a user to achieve a desirable skin tone without exposure to UV light.

[0005] Typical sunless tanning products may include solutions containing dihydroxyacetone (DHA) as the active ingredient. DHA causes a chemical reaction with the outer layer of the skin, resulting in a color change that gradually fades with the natural exfoliation of the skin. Erythrulose is another chemical that reacts with protein in the outer layer of the skin, producing a slower developing tan compared to DHA. Erythrulose may be used either separately or in conjunction with DHA. Other additives may be used in an application of sunless tanning solution, such as additional chemical boosters, scents, skin treatments, and other temporary coloring agents.

[0006] Temporary bronzers may also be applied to the skin, giving a temporary color that is easily removed. Temporary bronzers may be used alone or in conjunction with a sunless tanning solution that reacts with human skin. Temporary bronzers may include pigmented solutions. A custom temporary bronzer may be generated by mixing one or more pigmented solutions to achieve a custom bronzer color.

[0007] Both professional and at-home spraying devices are available on the market. However, if a customized solution is desired, the solution must be premixed for each application. If modification of the solution is desired, the procedure must be repeated until the desired solution is prepared in a single reservoir.

[0008] After a customized application of the customized solution, it is impractical to reuse the customized solution on another individual. In some cases, different solutions should not be premixed until immediately prior to the application of the product. In these cases, it is impractical to reuse any remaining customized solution, even on the same individual.

[0009] To overcome the problems and limitations described above, there is a need for an adjustable dual chamber spraying device.

[0061] FIG. 4 illustrates a cross sectional view of an exemplary valve core receiver in accordance with one or more methods, apparatus and/or systems described herein.

[0062] In FIG. 4, the cross-sectional view of valve core 24 intersects diverter 25. Valve core 24 is positioned in valve core receiver 46 at position 52. At position 52, first solution passage 40 is in fluid contact with output solution passage 48, while second solution passage 42 is blocked. In position 52, the output solution only contains the first solution drawn from first chamber 16 via first solution passage 40 when the system is pressurized.

[0063] Valve core 24 may be repositioned to position 54, such as by adjusting adjustment knob 14. In one or more embodiments, valve core 24 may be rotated from position 52 to position 54 using adjustment knob 14. At position 54, first solution passage 40 is blocked, while second solution passage 42 is in fluid contact with output solution passage 48. In position 54, the output solution only contains the second solution drawn from second chamber 18 via second solution passage 42 when the system is pressurized.

[0064] In one or more embodiments, valve core 24 may be positioned in between position 52 and position 54, allowing for the ratio of the first solution and the second solution to be adjusted, such as by using adjustment knob 14. For example, when first chamber 16 and second chamber 18 are equally pressurized, the ratio of the first solution and the second solution will be based on a partial or complete blockage of first solution passage 40 and/or second solution passage 42 based on the position of diverter 25 of valve core 24. In one or more embodiments, when valve core 24 is set to allow fluid from both chambers 16 and 18 to enter into core receiver 46, the fluids may form a mixture in core receiver 46 thus sending the desired mixture through output solution passage 48 based on the setting of adjustment valve 14.

[0065] In one or more embodiments, a first maximum position and the second maximum position are set beyond which valve core 24 is not permitted to travel, preventing blockage of output solution passage 48 by valve core 24. Alternatively, valve core 24 may freely rotate within valve core receiver 46. In one or more embodiments, repositioning of valve core 24 is allowed in discrete increments. Alternatively, repositioning of valve core 24 may be unrestricted.
