Abstract

The invention relates to filter-as-you-pour filtration container systems. Such a system may include a container body defining an internal storage volume for holding water, a lid that may be releasably attachable over the container body, and a filter assembly (e.g., disposed within the container body). The system includes an inlet through which unfiltered water is introduced into the container body, and an outlet through which filtered water may be poured. The filter assembly may be attachable to at least one of the lid or container body, and is disposed relative to the outlet so as to be in a flow stream of the water as the water is poured from the container. The filter media of the filter assembly may comprise an activated carbon fibrous textile material that presents a curved surface to the water. Such systems surprisingly provide for relatively high flow rates (e.g., at least 0.3 GPM).

First claim

1 . A filter-as-you-pour system configured to provide filtered water as water is poured from an outlet of the system, the system comprising:
a container body defining an internal storage volume for holding water; a lid that is releasably attachable over the container body; the system comprising an inlet through which unfiltered water may be introduced into the container body; the system comprising an outlet through which water within the container body may be poured and simultaneously filtered; a filter assembly attachable to at least one of the lid or the container body, the filter assembly being disposed so as to be in a flow stream of the water as the water is poured out of the container body through the outlet so that the stream of water exiting through the outlet is simultaneously filtered as it is poured from the container body, the filter assembly including filter media that comprises an activated carbon textile material that presents a curved surface to the flow stream of water such that an exit flow rate of water passing through the filter assembly and poured from the outlet is at least 0.3 GPM.

2 . The filter-as-you-pour system of claim 1 , wherein the exit flow rate of the water is from about 0.3 GPM to about 2 GPM.

3 . The filter-as-you-pour system of claim 1 , wherein the exit flow rate of the water is from about 0.3 GPM to about 1 GPM.

4 . The filter-as-you-pour system of claim 1 , wherein the exit flow rate of the water is from about 0.5 GPM to about 0.8 GPM.

5 . The filter-as-you-pour system of claim 1 , wherein the container body does not include a reservoir for holding unfiltered water separate from the internal storage volume of the container body.

6 . The filter-as-you-pour system of claim 1 , wherein the filter assembly is elongate and generally vertically oriented relative to the lid when horizontal, the filter assembly having a length to width ratio of at least 1:1.

7 . The filter-as-you-pour system of claim 6 , wherein the filter assembly is generally cylindrical, and includes a length to diameter ratio of at least 2:1.

8 . The filter-as-you-pour system of claim 6 , wherein the filter assembly includes a transverse cross-section that is generally 4-sided, wherein one of the sides of the 4-sided cross-section is crescent shaped.

9 . The filter-as-you-pour system of claim 6 , wherein the vertically oriented elongate filter assembly is releasably attachable to the lid at a location that is aligned with and below the outlet such that a longitudinal axis of the filter assembly is aligned with the outlet, all water poured through the outlet passing through the filter assembly so that water poured through the outlet is simultaneously filtered as it is poured from the container body.

10 . The filter-as-you-pour system of claim 1 , wherein the filter assembly is releasably attachable to the container body.

11 . The filter-as-you-pour system of claim 1 , wherein the system is configured to filter water only as water is poured out of the container body.

12 . The filter-as-you-pour system of claim 1 , wherein the inlet is disposed in the lid.

13 . The filter-as-you-pour system of claim 1 , wherein the outlet is disposed in the lid.

14 . The filter-as-you-pour system of claim 1 , wherein both the inlet and the outlet are disposed in the lid.

15 . The filter-as-you-pour system of claim 1 , wherein the filter assembly is a gravity flow filter.

16 . A filter-as-you-pour system configured to provide filtered water as water is poured from an outlet of the system, the system comprising:
a container body defining an internal storage volume; a lid that is releasably attachable over the container body, the lid including:
an inlet through which unfiltered water may be directly introduced into the container body without passing through a filter;
an outlet through which water within the container body may be poured, the unfiltered water being simultaneously filtered as it is poured out of the container body through the outlet; and
a vertically oriented elongate filter assembly releasably attachable to the lid at a location that is aligned with and below the outlet such that a longitudinal axis of the filter assembly is aligned with the outlet, all water poured through the outlet passing through the filter assembly so that water poured through the outlet is simultaneously filtered as it is poured from the container body.

17 . The filter-as-you-pour system of claim 16 , wherein an exit flow rate of the water as water is poured from the container body through the outlet is at least 0.3 GPM.

18 . The filter-as-you-pour system of claim 16 , wherein filter media of the filter assembly comprises an activated carbon textile material that presents a curved surface to the flow stream of water.

19 . The filter-as-you-pour system of claim 16 , wherein the filter assembly is elongate and generally vertically oriented relative to the lid when horizontal, the filter assembly having a length to width ratio of at least 1:1.

20 . The filter-as-you-pour system of claim 19 , wherein the filter assembly is generally cylindrical, and includes a length to diameter ratio of at least 2:1.
