Abstract

A connector system for a liquid container system for a spray gun includes a lid that includes a liquid outlet and an adapter. The adapter includes a spray gun end and a lid end. The ends are connected with a liquid-tight passageway. Further, the spray gun end is adapted for releasable engagement with a liquid inlet port of the spray gun and the lid end is adapted for releasable engagement with the liquid outlet. The connector system also includes a plurality of interlocking tab assemblies for releasably attaching the adapter to the lid. Each assembly includes a first tab and a second tab, wherein an end of the first tab is adapted to secure the adapter to the lid when the first tab and the second tab are interlocked.

First claim

What is claimed is:

1. A liquid container system for use with a gravity fed spray gun, comprising:
a liner comprising a closed end and an open end, wherein the liner is adapted to hold a liquid, and wherein the liner is adapted to collapse as the liquid is removed from the liquid container system of the gravity fed spray gun;
a paint cup adapted to hold the liner; and
a lid comprising an inlet, an outlet, a sidewall that terminates at the inlet, and an integral filter that is generally planar and positioned past the inlet along an interior portion of the lid, wherein the filter is spaced apart from the inlet,
wherein the liner further comprises at least one pleat; and
wherein no pleat of the liner is closer to the open end of the liner than the closed end of the liner.

2. The liquid container system of claim 1 , wherein the filter extends on a plane that is parallel to a plane overlying an opening of the inlet of the lid.

3. The liquid container system of claim 1 , wherein the filter is spaced apart from the outlet of the lid.

4. The liquid container system of claim 1 , wherein the at least one pleat is disposed along the sidewall perpendicular to a central axis of the liner and circumscribing the sidewall, wherein the sidewall extends between the closed end and the open end.

5. The liquid container system of claim 1 , wherein the filter is perpendicular to a central axis of the lid that runs through a center of the inlet and a center of the outlet.

6. A method of using a liquid container system, comprising:
providing a liquid container system, wherein the liquid container system comprises:
a liner comprising a closed end and an open end, wherein the liner is adapted to hold a liquid, and wherein the liner is adapted to collapse as the liquid is removed from the liquid container system of the gravity fed spray gun;
a paint cup adapted to hold the liner; and
a lid comprising an inlet, an outlet, a sidewall that terminates at the inlet, and an integral filter that is generally planar and positioned past the inlet along an interior portion of the lid, wherein the filter is closer to the outlet than the inlet, and wherein the filter is completely between the inlet and outlet;

filling the liner with a liquid; and
removing the liquid from the liner, the liquid moving from the liner and through the filter.

7. The method of claim 6 , wherein the filter is spaced apart from the outlet of the lid.

8. A liquid container system for use with a gravity fed spray gun, comprising:
a liner comprising a closed end and an open end, wherein the liner is adapted to hold a liquid, and wherein the liner is adapted to collapse as the liquid is removed from the liquid container system of the gravity fed spray gun;
a paint cup adapted to hold the liner; and

a lid comprising an inlet, an outlet, a sidewall that terminates at the inlet, and an integral filter that is generally planar and positioned past the inlet along an interior portion of the lid, wherein the filter is spaced apart from the inlet, wherein the filter has a diameter, wherein the outlet has a diameter, wherein the inlet has a diameter, wherein the diameter of the filter is smaller than the diameter of the inlet; wherein the filter is completely between the inlet and outlet; and wherein the diameter of the filter is larger than the diameter of the outlet.
