Abstract

A fluid container (10) for dispensing a first fluid and a consumable additive.
The fluid container (10) includes a first chamber (22) for containing a first fluid and an additive dispensing system (100). The first chamber (22) is configured such that the first fluid may be dispensed from the first chamber (22). The additive dispensing system (100) selectively operable to dispense an amount of additive and is not in fluid communication with the first chamber (22).

Claims (25)

1. A fluid container for dispensing a first fluid and a consumable additive, comprising:
a first chamber for containing a first fluid and configured such that the first fluid may be dispensed from the first chamber; and an additive dispensing system selectively operable to dispense an amount of additive;
wherein the additive dispensing system is not in fluid communication with the first chamber.
2. The fluid container according to claim 1, wherein the additive dispensing system comprises a first additive reservoir configured to contain a consumable additive and a pump selectively operable to dispense an amount of additive from the first additive reservoir.
3. The fluid container according to claim 2, further comprising a second additive reservoir disposed adjacent to the additive dispensing system such that it may receive the amount of additive dispensed from the pump, separate from the first fluid;
wherein the fluid container is configured such that when tilted an amount of first fluid may pour from the first chamber and the amount of additive may pour from the second additive reservoir.
4. The fluid container according to claim 3, further comprising a deflector positioned substantially in front of the pump such that it deflects the amount of additive dispensed from the pump into the second additive reservoir.
5. The fluid container according to claim 3, further comprising a receptacle positioned above the first chamber, and wherein the additive dispensing system comprises a housing that movingly engages the receptacle such that the housing moves within the receptacle when a force is applied to an end of the housing to selectively operate the pump.
6. The fluid container according to claim 5, further comprising an actuator configured to movingly engage the end of the housing to apply a force to the end.
7. The fluid container according to claim 1, further comprising a lid configured to removably engage an opening of the fluid container in a position over the first chamber.
8. The fluid container according to claim 3, further comprising a spout, and wherein the second additive reservoir is partially positioned above the spout.
9. The fluid container according to claim 1, further comprising a life indicator configured to track a cumulative number of dispenses of the amount of additive from the additive dispensing system and indicate the corresponding life remaining for the additive dispensing system based upon the cumulative number of dispenses of the amount of additive.
10. The fluid container according to claim 1, wherein the first fluid contained within the first chamber is filtered water.
11. The fluid container according to claim 3, wherein the second additive reservoir includes an ultrahydrophobic, ultralyophobic, or ultraclean surface.
12. The fluid container according to claim 3, wherein the second additive reservoir comprises one or more rinse channels along edges of the second additive reservoir, and wherein the one or more rinse channels are in fluid communication with the first chamber and the second additive reservoir in order to carry the first fluid into the second additive reservoir to rinse the second additive reservoir when the fluid container is tilted.
13. The fluid container according to claim 3, wherein the second additive reservoir comprises flow channels to direct the additive towards a lip of the second additive reservoir.
14. The fluid container according to claim 3, wherein the second additive reservoir comprises an elevated section adjacent to the additive dispensing system to collect additive between the elevated section and a lip of the second additive reservoir.
15. The fluid container according to claim 1, further comprising a second chamber and a filter, wherein the filter is positioned between the first and second chambers and is in fluid communication with the first and second chambers such that an unfiltered first fluid may flow from the second chamber through the filter and enter into the first chamber as a filtered first fluid.
16. The fluid container according to claim 15, further comprising a life indicator that is configured to indicate the corresponding life remaining for the filter.
17. The fluid container according to claim 16, wherein the life indicator is a volume-based indicator or time-based indicator.
18. The fluid container according to claim 2, wherein the pump comprises:
an inlet check valve in fluid communication with the first additive reservoir;
a diaphragm positioned over the inlet check valve defining a chamber between the valve and the diaphragm; and an outlet check valve disposed on the diaphragm and in fluid communication with the chamber;
wherein the outlet check valve is configured to open when pressure is applied to the diaphragm to dispense the amount of additive.
19. The fluid container according to claim 1, wherein the fluid container is a pitcher.
20. A fluid container for dispensing a first fluid and a consumable additive, comprising:
a first fluid chamber for containing a first fluid;
an additive dispensing system disposed adjacent to the first fluid chamber and operable to dispense an amount of additive; and a second additive reservoir disposed adjacent to the additive dispensing system such that it may receive and contain the amount of additive dispensed from the additive dispensing system separate from the first fluid chamber;
wherein the fluid container is configured such that when tilted an amount of first fluid may pour from the first fluid chamber and the amount of additive may pour from the second additive reservoir.
21. The fluid container according to claim 20, wherein first chamber comprises a first chamber pour angle .theta. relative to a vertical axis and second additive reservoir comprises a second additive reservoir pour angle a relative to the vertical axis, and wherein second additive reservoir pour angle a is less than first chamber pour angle .THETA..
22. The fluid container according to claim 20, wherein second additive reservoir comprises a lip having a lip radius of equal to or less than 0.005 inches.
23. A fluid container for dispensing a first fluid and a consumable additive, comprising:
a first fluid chamber for containing a first fluid;
an additive dispensing system disposed adjacent the first fluid chamber and selectively operable to dispense an amount of additive; and a surface downstream of and adjacent to the additive dispensing system that is ultrahydrophobic, ultralyophobic, or ultraclean.
24. The fluid container according to claim 23, wherein the ultrahydrophobic, ultralyophobic, or ultraclean surface comprises a bubble structure made with a material with surface energy lower than 25 mN/m.
25. The fluid container according to claim 23, wherein the ultrahydrophobic, ultralyophobic, or ultraclean surface comprises a bubble structure coated with nanoparticles or a fluoropolymer via plasma coating.
