Abstract

The invention relates to lid bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such lid bodies may be releasably attachable to the filter assembly through complementary locking structures of the lid body and the filter assembly so that the lid body may be selectively and releasably attached to the filter assembly. The lid bodies may also comprise a locking structure that is configured to releasably engage with a complementary locking structure of a container body. The lid bodies may also be configured to be directly connected to filter assemblies.

First claim

The invention claimed is:

1. A filter-as-you-pour system, the system comprising:
a container body having a container wall defining an internal storage volume;
a lid body that is releasably attachable over the container body, the lid body having a main surface and a side wall extending from the main surface;
an outlet for water to flow out of the system;
an inlet through the lid body through which unfiltered water may be introduced into the internal storage volume of the container body while the system is assembled; and
an elongated filter assembly attachable to the lid body, the filter assembly having an inner core frame member surrounded by a textile filter media and a shell sandwiching the textile filter media between the inner core frame and the shell to present a curved surface of the textile filter media to the unfiltered water, wherein when attached to the lid body, the filter assembly being disposed so as to be in a flow stream of the water only as the water is poured out of the container body through the outlet so that the stream of water exiting through the outlet is filtered as it is poured from the container body, so that all water exiting through the outlet passes through the filter assembly before exiting through the outlet;
where the lid body is releasably attachable to the filter assembly through complementary locking structures of the lid body and the filter assembly so that the lid body may be selectively and releasably attached to the filter assembly.

2. The system of claim 1 , where the textile filter media of the filter assembly comprises an activated carbon textile material that presents the curved surface to the flow stream of water.

3. The system of claim 1 , wherein the shell includes slots configured to enable water to flow into the filter assembly from the container body in a radial direction toward a longitudinal axis of the filter assembly, and flow out towards the outlet in an axial direction.

4. The system of claim 3 , where wherein the filter assembly is configured to enable water to flow into the filter assembly at an outer perimeter of the filter assembly, and flow out of the filter assembly along a longitudinal axis of the filter assembly.

5. The system of claim 3 , wherein the outlet of the system is formed through the side wall of the lid body and oriented laterally relative to a longitudinal axis of the filter assembly, so that the water flows into the filter assembly in a first radial direction toward the longitudinal axis of the filter assembly, flows out towards the outlet in a second radial direction away from the longitudinal axis of the filter assembly, and finally flows out the outlet in a single lateral direction relative to and away from the longitudinal axis of the filter assembly.

6. The system of claim 1 , where the system is configured to provide a minimum flow rate of 0.3 gallons per minute.

7. The system of claim 1 , where the lid body and the container body each respectively comprise complementary locking structures configured to releasably engage one another so that the lid body may be selectively and releasably attached to the container body.

8. The system of claim 1 , where the outlet is disposed in the lid body, and wherein the filter assembly screws into the lid body at a location within or surrounding the outlet.

9. The system of claim 1 , where the filter assembly and lid body include means for indicating that the lid body and filter assembly have been correctly connected together so as to prevent water from bypassing the filter assembly.

10. The system of claim 9 , where the means for indicating that the lid body and filter assembly have been correctly connected together is selected from the group consisting of: (i) a light that illuminates or goes off upon correct connection; (ii) differently colored portions of the lid body and filter assembly which upon alignment and correct connection with one another form a third color; (iii) differently textured or patterned portions of the lid body and filter assembly which upon alignment and correct connection with one another form a third texture or pattern; (iv) an auditory signal provided upon correct connection; and (v) combinations thereof.

11. The system of claim 1 , wherein the filter assembly is attached to the lid body by way of a plurality of protrusions extending from one of the lid body or the filter assembly that are sized to fit and be retained within a plurality of recesses in the other of the lid body or filter assembly such that when the plurality of protrusions are engaged in the plurality of recesses they are configured to firmly fit together.

12. The system of claim 1 , wherein the lid body includes a first indicia indicating member and the filter assembly includes a second indicia indicating member, wherein upon the filter assembly being correctly connected to the lid body, a third indicia is formed by the first and second indicia indicating members.

13. The system of claim 1 , wherein the inlet in the lid body is configured to allow water to be introduced into the internal storage volume of the container body along a first axis, the filter assembly is configured to allow the water to radially pass through the filter assembly toward a longitudinal axis of the filter assembly, flow along the longitudinal axis and radially out of the filter away from the longitudinal axis through the outlet in the container body in a direction substantially perpendicular to the first axis.

14. A filter-as-you-pour system, the system comprising:
a container body defining an internal storage volume;
a lid body comprising an outlet through which filtered water is poured out of the container body and an inlet through which water is introduced into the container body, the lid body being releasably attachable to the container body; and
an elongated filter assembly configured to releasably attach to the lid body around the outlet of the lid body, the filter assembly having an inner core frame member surrounded by a textile filter media and a shell sandwiching the textile filter media between the inner core frame and the shell to present a curved surface of the textile filter media to unfiltered water, wherein when attached to the lid body, all water flowing through the outlet passes through the filter assembly before passing through the outlet as water is poured out of the container body;
where the lid body is configured so that water introduced into the container body through the inlet flows directly into the container body without first flowing through a filter or a reservoir while the system, including the container body, lid body, and filter assembly, are assembled; and
where the lid body and the container body comprise respective sets of complementary locking structures configured to releasably engage one another so that the lid body may be selectively and releasably attached to the container body.

15. The system of claim 14 , where the textile filter media of the filter assembly comprises an activated carbon textile material that presents the curved surface to a flow stream of water.

16. The system of claim 14 , wherein the shell includes slots configured to enable water to flow into the filter assembly from the container body in a radial direction toward a longitudinal axis of the filter assembly, and flow out of the filter towards the outlet in an axial direction.

17. The system of claim 14 , where the system is configured to provide a minimum flow rate of 0.3 gallons per minute.

18. The system of claim 14 , where the filter assembly and lid body include mea
