Water pitcher with filter

摘要

A water pitcher system that includes a water receiving aperture configured to allow water to be delivered into an interior water storage volume defined by a base and at least one upwardly extending wall extending upward from the base. The at least one upwardly extending wall includes an inner fluid facing wall section having an inner fluid facing surface and an outer user facing wall section having an exterior, user facing surface where the inner fluid facing wall section and the outer user facing wall section are each composites of a plastic substrate and a glass layer, typically deposited by vapor deposition or blow-molding, onto the plastic substrate. The inner fluid facing surface and the outer user facing surface are the glass layers.

主权项

1. A water pitcher in combination with a gravity-driven water filtration system comprising:
the gravity-driven water filtration system including a bottom portion having a treated water outlet opening, an upper perimeter, and a bottom portion side wall that defines an interior volume of the bottom portion, and wherein the bottom portion side wall is a shaped surface configured to frictionally engage a plurality of differently sized water apertures and still deliver treated water through the treated water outlet opening; the gravity-driven filtration system including a water filter comprising a container and a water treatment medium positioned within the container, wherein the container is operably engaged with the bottom portion and has intake openings in an upper portion thereof and outlet openings in a lower portion thereof, whereby the outlet openings of the container deliver treated water to the interior volume of the bottom portion and the treated water flows out of the interior volume of the bottom portion through the treated water outlet opening of the bottom portion; the gravity-driven filtration system including a top portion having an interior volume defined by a side wall, a water inlet opening at a top of the top portion, and a bottom perimeter defining a water outlet opening, and wherein the water inlet opening of the top portion is configured to receive untreated water, and the water outlet opening of the top portion is configured to allow untreated water to flow into contact with the inlet openings in the upper portion of the water filter; and wherein the water filter is configured to be removably engaged by hand without the use of tools from the bottom portion, and the water filter, the bottom portion and the top portion are each configured to be removably engaged and disengaged to allow for replacement of the water filter and reassembly of the overall gravity-driven water filtration system filtering by hand and without the use of tools; the water pitcher including a water receiving aperture configured to allow a water to be delivered into an interior water storage volume, wherein the interior water storage volume is defined by at least one upwardly extending wall extending upward from a base, wherein the water receiving aperture is engaged by the gravity-driven water filtration system; wherein the at least one upwardly extending wall comprises an inner, water facing wall section having an inner water facing surface and an outer user facing wall section having an outer user facing surface wherein the inner water facing wall section comprises a material chosen from the group consisting of glass, stainless steel, gold, silver, and mixtures thereof, and the outer user facing wall section comprises a material chosen from the group consisting of glass, plastic, and stainless steel; and wherein the inner water facing surface and the outer user facing surface are not both glass unless the glass is blow molded or vapor deposited as a layer onto another media chosen from the group consisting of a plastic, a metal, and mixtures thereof thereby forming a composite material with glass layer on at least one of the inner, facing wall section and the outer user facing wall section.
