US 2020/0392016 A1 · Water Bottle With a Filter Structure and a Method Therefor

Abstract

An on-demand filter structure including a first hydrophilic protective layer comprising a first surface exposable to a stream of water. A contact area on the first surface receives the stream. The first hydrophilic protective layer receives the stream and distributes water out a second surface, primarily using gravity. An activated carbon felt (ACF) layer is adjacent to the second surface, wherein the ACF layer is configured for water filtration, primarily using gravity. A second hydrophilic protective layer includes a third surface adjacent the ACF layer and a fourth surface. The third surface receives filtered water from the ACF layer, and the fourth surface expels the filtered water primarily using gravity, wherein the first and second hydrophilic protective layers sandwich the ACF layer. A cross section of the first hydrophilic protective layer, the ACF layer, and the second hydrophilic protective layer has a curvature.

Dependent claims

A water bottle with a filter structure, comprising:

a portable water bottle having a support structure and a reservoir;
and
a filter assembly configured to be supported by the support structure, including:
a first hydrophilic protective layer having a first surface and a second surface, wherein the first surface is opposed to the second surface,
a second hydrophilic protective layer having a third surface and a fourth surface, wherein the third surface is opposed to the fourth surface, and
a single activated carbon felt (ACF) layer having a fifth surface and a sixth surface, wherein the ACF layer is disposed between the first hydrophilic protective layer and the second hydrophilic protective layer, wherein the fifth surface of the ACF layer contacts the second surface of the first hydrophilic protective layer and the sixth surface of the ACF layer contacts the third surface of the second hydrophilic protective layer;
wherein the filter assembly is formed with the ACF layer sandwiched between the first hydrophilic protective layer and the second hydrophilic protective layer.
