Abstract

The invention relates to container bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such container bodies may have an undivided internal storage volume, so as to not include a reservoir compartment for unfiltered water. They may be part of systems configured to filter water both as water is introduced into a container body of the system and as water is poured from the container body of the system. The filter assembly may be attached to the container body at a location proximate the outlet of the system. Filter media of the filter assembly may comprise an activated carbon textile material that presents a curved surface to water passing through the filter assembly. The container body may be configured as a pitcher, carafe, water bottle, jug, or other shaped container.

First claim

What is claimed is:

1. A filter-as-you-pour system configured to filter water as the water is poured from the system, comprising:
a container body defining an internal storage volume extending from a closed bottom to an open top;
a lid body attachable to the open top of the container body, the lid body defining a fluid outlet;
a filter assembly attachable to the lid body, the filter assembly including a frame member extending between a first closed end to a second open end, the frame member comprising a plurality of circumferential support members and a plurality of axial support members coupled to the circumferential support members to define a plurality of openings that pass to a central hollow section in the filter assembly; and
an activated carbon textile filter media wrapped around the frame member and in contact with the frame member from the first closed end to the second open end of the frame member along an entire length of the activated carbon textile filter media to present a curved surface to the water entering and passing through a curved surface of the filter assembly;
wherein as the water is poured from the container body and exits through the fluid outlet of the lid body, all the water exiting through the fluid outlet passes through the filter assembly to filter the water before exiting through the fluid outlet.

2. The filter-as-you-pour system of claim 1 , wherein the second open end of the filter assembly includes an open and non-partitioned filter top extending from the central hollow section to freely pass the water through the open and non-partitioned filter top to the fluid outlet in the lid body.

3. The filter-as-you-pour system of claim 2 , wherein the filter assembly includes the frame member with the activated carbon textile filter media wrapped there around and a shell sandwiching and contacting the activated carbon textile filter media between the frame member and the shell, wherein the shell includes slots configured to enable the water to flow into the curved surface of the filter assembly from the container body in a radial direction toward a longitudinal axis of the filter assembly, and flow out of the open and non-partitioned filter top of the filter assembly towards the fluid outlet in the lid body in an axial direction.

4. The filter-as-you-pour system of claim 1 , wherein the system is configured to provide a minimum flow rate of 0.3 gallons per minute.

5. The filter-as-you-pour system of claim 1 , wherein the container body is a water bottle shaped container body.

6. The filter-as-you-pour system of claim 5 , wherein the water bottle shaped container body is substantially cylindrical and the lid body is substantially circular.

7. The filter-as-you-pour system of claim 6 , wherein a diameter of the container body substantially corresponds to a diameter of the lid body.

8. The filter-as-you-pour system of claim 1 , wherein the second open end of the filter assembly is threadably coupled to an annular threaded locking structure extending from the lid body.

9. The filter-as-you-pour system of claim 8 , wherein the filter assembly is attached at a center of the lid body.

10. The filter-as-you-pour system of claim 8 , wherein the filter assembly is attached off-center from the lid body.

11. The filter-as-you-pour system of claim 1 , wherein the lid body further includes a downward facing lip having an outer ridged surface.

12. The filter-as-you-pour system of claim 1 , wherein a fluid inlet and the fluid outlet extend through a single opening.

13. The filter-as-you-pour system of claim 1 , wherein the filter assembly comprises a gravity flow filter having a flow rate from about 0.3 gallons per minute to about 2 gallons per minute.

14. The filter-as-you-pour system of claim 1 , wherein the frame member of the filter assembly includes a threaded cylindrical neck configured to threadably attach to the lid body adjacent the fluid outlet.

15. The filter-as-you-pour system of claim 11 , wherein the downward facing lip includes an internal threaded surface configured to threadably engage an outer threaded surface of the container body.

16. The filter-as-you-pour system of claim 1 , wherein the activated carbon textile filter media extends from a bottom edge at the first closed end of the frame member to a top edge at the second open end.

17. A filter-as-you-pour system configured to filter water as the water is poured from the system, comprising:
a container body defining an internal storage volume extending from a closed bottom to an open top;
a lid body attachable to the open top of the container body, the lid body defining a fluid outlet;
a filter assembly attachable to the lid body, the filter assembly including an inner hollow core frame member extending between a first closed end to a second open end and a shell positioned over the inner hollow core frame member, the shell includes slots configured to enable the water to flow into the filter assembly from the container body in a radial direction toward a longitudinal axis of the filter assembly; and
a filter media comprising an activated carbon textile material, the activated carbon textile material wrapped around and in contact with an entire length of a sidewall of the inner hollow core frame member from the first closed end to the second open end to define a central hollow section and to present an annular curved surface to the water entering and passing through the activated carbon textile material;
wherein the shell sandwiches and contacts the activated carbon textile material between the inner hollow core frame member and the shell.

18. The filter-as-you-pour system of claim 17 , wherein the filter assembly includes an open and non-partitioned filter top extending from the central hollow section such that all the water exiting through the fluid outlet passes through the filter assembly and through the open and non-partitioned filter top to the fluid outlet.

19. The filter-as-you-pour system of claim 17 , wherein the filter assembly comprises a gravity flow filter having a flow rate from about 0.3 gallons per minute to about 2 gallons per minute.

20. The filter-as-you-pour system of claim 17 , wherein the inner hollow core frame member of the filter assembly includes a threaded cylindrical neck configured to threadably attach to an annular threaded locking structure extending from the lid body and about the fluid outlet of the lid body.

21. The filter-as-you-pour system of claim 17 , wherein a fluid inlet and the fluid outlet extend through a single opening.
