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 lid comprising an inlet, an outlet, a sidewall that terminates at the inlet, a filter that is generally planar and positioned in an interior portion of the lid and positioned completely between the inlet and outlet, and 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, and wherein the diameter of the filter is larger than the diameter of the outlet; and
a ring configured to engage at least a portion of the lid in an unassembled state, wherein the lid, ring, and liner are fixedly attached in the unassembled state.

2. The liquid container system of claim 1 , wherein the lid and the ring are configured to rotate relative to each other.

3. The liquid container system of claim 1 , wherein the lid comprises at least one projection extending axially outward from an outer surface of the lid.

4. The liquid container system of claim 1 , wherein the ring is removably attached to the lid.

5. The liquid container system of claim 1 , wherein the ring comprises one or more protrusions that project radially outward.

6. The liquid container system of claim 5 , wherein the one or more protrusions of the ring that project radially outward are circumferentially spaced along an outside surface of the ring.

7. The liquid container system of claim 5 , wherein the one or more protrusions of the ring that project radially outward intersect a terminal edge of the ring.

8. The liquid container system of claim 5 , wherein the one or more protrusions that project radially outward are discrete and separated from each other.

9. The liquid container system of claim 5 , wherein the one or more protrusions of the ring that project radially outward are discrete and spaced apart from each other around at least a portion of the circumference of the ring.

10. The liquid container system of claim 9 , wherein the one or more protrusions of the ring further extend axially for at least a portion of a thickness of the ring.

11. The liquid container system of claim 1 , wherein the ring is configured to rotate about an axis of the lid.

12. The liquid container system of claim 1 , further comprising a paint cup adapted to engage the ring.

13. The liquid container system of claim 12 , wherein an assembly in the assembled state includes the lid, liner, ring, and paint cup.

14. The liquid container system of claim 12 , wherein the ring is configured to engage at least a portion of the paint cup in the assembled state.

15. The liquid container system of claim 14 , wherein the ring comprises at least one rib segment configured for closing the assembly into the assembled state.

16. The liquid container system of claim 1 , wherein the ring further comprises internal protrusions.

17. The liquid container system of claim 16 , wherein in an assembled state, a portion of the liner is between the ring and the lid.

18. The liquid container system of claim 1 , wherein the filter is bonded to the lid and wherein the lid has no obstruction to the flow of liquid between the inlet and the filter.

19. The liquid container system of claim 1 , wherein the filter is bonded to the lid.

20. The liquid container system of claim 19 , wherein the filter is bonded to the lid at an internal radial protrusion of the lid.

21. The liquid container system of claim 19 , wherein the filter is substantially bonded to the lid only on a single planar side.

22. The liquid container system of claim 21 , wherein at least one portion of the interior wall of the lid between the filter and the outlet has a curved contour as viewed in cross-section.
