Abstract

A system, including a gravity fed container assembly, including a container, a lid configured to cover a chamber in the spray coating supply container, wherein the chamber is configured to hold a spray material, a filter assembly within the chamber and configured to filter the spray material in the chamber, and a valve coupled to the filter assembly and configured to open when the container couples to a spray device, wherein the valve is configured to move the filter assembly from a first position to a second position, wherein the first position blocks the filter assembly from filtering the spray material and the second position enables filtering of the spray material.

First claim

The invention claimed is:

1. A system, comprising:
a gravity fed container assembly, comprising;
a container;
a lid configured to cover a chamber in the spray coating supply container, wherein the chamber is configured to hold a spray material;
a filter assembly within the chamber and configured to filter the spray material in the chamber; and
a valve coupled to the filter assembly and configured to open when the container couples to a spray device;
wherein the valve is configured to move the filter assembly from a first position to a second position, wherein the first position blocks the filter assembly from filtering the spray material and the second position enables filtering of the spray material, wherein the container comprises a conical bottom wall, the valve comprises a circular portion configured to seal with the conical bottom wall, and the valve comprises a base portion coupled to the circular portion, and the base portion comprising ribs or panels that are configured to allow the spray material to pass through the valve in the second position.

2. The system of claim 1 , wherein the filter assembly comprises an outer ring.

3. The system of claim 2 , wherein the filter assembly comprises at least one support arm extending from the outer ring to the valve.

4. The system of claim 3 , wherein the filter assembly comprises a conical screen extending from the outer ring to the valve.

5. The system of claim 3 , wherein the at least one support arm is configured to spring bias the valve.

6. The system of claim 1 , wherein the filter assembly rests on the conical bottom wall in the first position, and the filter assembly extends away from the conical bottom wall in the second position.

7. The system of claim 1 , wherein the container comprises a plurality of volumetric marks.

8. The system of claim 7 , wherein the container comprises translucent or transparent wall having the plurality of volumetric marks.
