Abstract

On example of a fluid dispensing system includes an unfiltered water container body defining an internal storage volume configured to hold a volume of water, a fluid outlet arranged for fluid communication with the internal storage volume, and a filter element positioned in the internal storage volume. With this configuration, a water dispensing process can be performed in which a single continuous stream of unfiltered water from the unfiltered water container body can pass through the filter element and be dispensed from the unfiltered water container body as a stream of filtered water. A water soluble tablet with an additive is positioned in the internal storage volume downstream of the filter medium such that the filtered water can pass out of the filter element and into contact with the water soluble tablet before being dispensed from the fluid outlet.

First claim

What is claimed is:

1. A fluid dispensing system, comprising:
an unfiltered water container body defining an internal storage volume configured to hold a volume of unfiltered water;
a lid body that is releasably attachable over the unfiltered water container body;
an inlet through the lid body through which unfiltered water may be introduced into the internal storage volume of the unfiltered water container body while the system is assembled;
a fluid outlet arranged for fluid communication with the internal storage volume of the unfiltered water container body, the fluid outlet passing through the lid body and spaced apart from the inlet to pass the filtered water out of the fluid dispensing system;
a filter element positioned in the internal storage volume of the unfiltered water container body and configured and arranged such that a water dispensing process can be performed in which a single continuous stream of unfiltered water from the unfiltered water container body can pass through the filter element and be dispensed out from the unfiltered water container body as a stream of filtered water; and
a water soluble tablet that comprises one or more additives and is positioned in the internal storage volume downstream of the filter element and positioned at the fluid outlet such that the filtered water can pass out of the filter element and into contact with the water soluble tablet prior to being dispensed out from the fluid outlet and out of the fluid dispensing system.

2. The fluid dispensing system as recited in claim 1 , wherein the filter element is an element of a filter assembly that is positioned in the internal storage volume of the unfiltered water container body, and the water soluble tablet is positioned within the filter assembly.

3. The fluid dispensing system as recited in claim 2 , wherein the filter assembly is detachably connectible to the lid.

4. The fluid dispensing system as recited in claim 2 , wherein the water soluble tablet is configured in the form of an annular filter core cover positioned at an outlet end of a filter core of the filter assembly, wherein the filter element is positioned around the filter core.

5. The fluid dispensing system as recited in claim 1 , wherein the unfiltered water container body comprises a pitcher.

6. The fluid dispensing system as recited in claim 1 , wherein the water soluble tablet is configured to be replaced at approximately the same time as the filter element.

7. The fluid dispensing system as recited in claim 1 , wherein the water soluble tablet delivers a substantially consistent concentration of additive to filtered water passing into contact with the water soluble tablet.

8. The fluid dispensing system as recited in claim 1 , wherein the water soluble tablet has a generally donut-shaped configuration including a hole through which the filtered water is able to pass.

9. The fluid dispensing system as recited in claim 1 , wherein the one or more additives in the water soluble tablet comprise any one or more of a nutritional additive, an agent, or a flavoring additive.

10. The fluid dispensing system as recited in claim 1 , wherein the filter element comprises ACF.

11. The fluid dispensing system as recited in claim 1 , wherein the filter element has a filter media configured to provide an exit flow rate of the fluid from the container in one or more of the following ranges: a range of about 0.3 GPM to about 2 GPM; a range of about 0.3 GPM to about 1 GPM; or a range of about 0.5 GPM to about 0.8 GPM.

12. The fluid dispensing system as recited in claim 1 , wherein the inlet through the lid defines a fill path configured to allow unfiltered water to be directly introduced into the internal storage volume of the unfiltered water container body without passing through a filter.

13. A fluid dispensing system, comprising:
an unfiltered water container body defining an internal storage volume configured to hold a volume of unfiltered water;
a fluid outlet arranged for fluid communication with the internal storage volume of the unfiltered water container body;
a filter element positioned in the internal storage volume of the unfiltered water container body and configured and arranged such that a water dispensing process can be performed in which a single continuous stream of unfiltered water from the unfiltered water container body can pass through the filter element and be dispensed out from the unfiltered water container body as a stream of filtered water; and
a water soluble tablet that comprises one or more additives and is positioned in the internal storage volume downstream of the filter element and positioned at the fluid outlet such that the filtered water can pass out of the filter element and into contact with the water soluble tablet prior to being dispensed out from the fluid outlet and out of the fluid dispensing system;
wherein the filter element is an element of a filter assembly that is positioned in the internal storage volume of the unfiltered water container body, and the water soluble tablet is positioned within the filter assembly;
wherein the filter element includes a frame comprising a body having a first end and an opposing second end, the body defining one or more openings, the frame defining a channel within the body; and
an activated carbon textile filter media wrapped around the body to cover the one or more openings defined in the body;
the first end being closed and the second end being open to the channel;
wherein the water soluble tablet is positioned at the second open end relative to the channel and at the fluid outlet.

14. The fluid dispensing system as recited in claim 13 , wherein the water soluble tablet is configured to be replaced the same time as the filter element.

15. The fluid dispensing system as recited in claim 13 , wherein the water soluble tablet delivers a substantially consistent concentration of additive to filtered water passing into contact with the water soluble tablet.

16. The fluid dispensing system as recited in claim 13 , wherein the water soluble tablet has a generally donut-shaped configuration including a hole through which filtered water is able to pass.

17. The fluid dispensing system as recited in claim 13 , wherein fluid from the internal storage volume does not contact the water soluble tablet except when a dispensing operation is being performed.

18. The fluid dispensing system as recited in claim 13 , wherein the one or more additives in the water soluble tablet comprise any one or more of a nutritional additive, an agent, or a flavoring additive.

19. The fluid dispensing system as recited in claim 13 , wherein the unfiltered water container body is rigid.

20. The fluid dispensing system as recited in claim 13 , wherein the water soluble tablet has an annular shape with a bore passing therethrough, the bore aligned with the channel in the frame.
