Abstract

A reservoir system for use with a spray gun. The system includes a cup receptacle and a lid. The lid includes a lid body and a collar. The lid body provides a spout and a platform surrounding the spout. At least a portion of the platform forms a partial helical shape revolving about a central axis of the spout. The collar is rotatably connected to the lid body. Further, the collar includes a lid connector structure configured to connect the lid to the cup receptacle. In some embodiments, the reservoir system further includes one or more of an adaptor, a plug and a shaker core.

First claim

What is claimed is:

1. A lid for a spray gun reservoir system comprising:
a lid body comprising:
a spout;
a platform at least partially surrounding the spout, wherein the platform defines a major plane and a partial helical shape declining with respect to the major plane and revolving about a central axis of the spout; and
a wall comprising an outer face adjoining the platform and comprising a portion that is declining with respect to the major plane of the platform;

wherein the partial helical shape begins in the major plane and interrupts the declining portion of the outer face of the wall, and
wherein the lid is configured to directly or indirectly attach to a spray gun.

2. The lid of claim 1 , wherein the declining portion of the outer face of the wall comprises a dome shape.

3. The lid of claim 1 , wherein the declining portion of the outer face of the wall comprises a conical shape.

4. The lid of claim 1 , wherein a first end of the partial helical shape is proximate a transition zone to the major plane and a second end of the partial helical shape interrupts the declining portion of the outer face of the wall.

5. The lid of claim 4 , wherein the second end of the partial helical shape terminates at a retention feature.

6. The lid of claim 1 , further comprising a collar rotatably connected to the lid body.

7. The lid of claim 6 , wherein the collar includes a lid connector structure configured to connect the lid to a compatible cup receptacle.

8. A lid for a spray gun reservoir system comprising:
a lid body comprising a spout and a platform at least partially surrounding the spout, wherein at least a portion of the platform forms a partial helical shape revolving about a central axis of the spout, and
a collar rotatably connected to the lid body;
wherein the collar includes a lid connector structure configured to connect the lid to a compatible cup receptacle.

9. The lid of claim 8 , wherein the platform defines a major plane and the partial helical shape declines with respect to the major plane, and further wherein the lid body includes a wall comprising an outer face adjoining the platform and comprising a portion that is declining with respect to the major plane of the platform, and even further wherein the partial helical shape interrupts the declining portion of the outer face of the wall.

10. The lid of claim 9 , wherein the declining portion of the outer face of the wall comprises a dome shape.

11. The lid of claim 9 , wherein the declining portion of the outer face of the wall comprises a conical shape.

12. The lid of claim 9 , wherein a first end of the partial helical shape is proximate a transition zone to the major plane and a second end of the partial helical shape interrupts the declining portion of the outer face of the wall.

13. The lid of claim 12 , wherein the second end of the partial helical shape terminates at a retention feature.

14. A reservoir system for use with a spray gun, the system comprising:
a cup receptacle; and
a lid including:
a lid body providing a spout and a platform surrounding the spout, wherein at least a portion of the platform forms a partial helical shape revolving about a central axis of the spout, and
a collar rotatably connected to the lid body;

wherein the collar includes a lid connector structure configured to connect the lid to the cup receptacle.

15. The reservoir system of claim 14 , wherein the cup receptacle includes a cylindrical side wall extending from a base end to an open end and defining an inner cavity, and further wherein an aperture is defined in the side wall that is open to the inner cavity for viewing contents of the inner cavity from an exterior of the cup receptacle, and even further wherein the aperture has a non-uniform circumferential width.

16. The reservoir system of claim 15 , wherein the aperture extends from a first side proximate the base end to an opposing, second side proximate the open end, and further wherein a circumferential width of the aperture at the first side is greater than a circumferential width of the aperture at the second side.

17. The reservoir system of claim 14 , wherein lid body includes an outer face defining a continuous dome shape, and further wherein the platform defines a ramp surface having a first ramp segment extending from a first end to a second end, the first end being longitudinally above the second end relative to an upright orientation of the lid, and even further wherein the ramp surface segment projects into the dome shape of the outer face.

18. The reservoir system of claim 17 , wherein the ramp surface further includes a second ramp segment extending from a first end to a second end, the first end of the second ramp segment being adjacent and longitudinally above the second end of the first ramp segment, and further wherein the lid body forms an undercut at an intersection of the first and second ramp segments, the undercut projecting into the dome shape of the outer face.

19. The reservoir system of claim 17 , wherein a radial width of the first ramp segment at the first end is less than a radial width of the first ramp segment at the second end.

20. The reservoir system of claim 14 , wherein the collar includes a ring and a plurality of tabs projecting from an underside of the ring, a portion of the lid connector structure being carried by at least one of the tabs, and further wherein the ring has a variable radial width.

21. The reservoir system of claim 20 , wherein circumferentially adjacent ones of the tabs are separated by a circumferential opening, and further wherein a radial width of the ring decreases at a location longitudinally aligned with at least one of the circumferential openings.

22. The reservoir system of claim 20 , wherein the ring defines at least one slot that is aligned with a corresponding one of the tabs.

23. The reservoir system of claim 14 , further comprising an adaptor configured to selectively connect the spout with a spray gun inlet.

24. The reservoir system of claim 23 , wherein the lid and the adaptor include complementary connector features for selectively mounting the adaptor to the lid.

25. The reservoir system of claim 23 , wherein the adaptor includes a tubular member and a base projecting from the tubular member, and further wherein the tubular member terminates at an end and the base defines a tracking face opposite the end, and even further wherein at least a portion of the tracking face forms a partial helical shape corresponding with the partial helical shape of the platform.

26. The reservoir system of claim 23 , wherein the adaptor further includes at least one lock structure projecting from an outer face of the base.

27. The reservoir system of claim 26 , wherein the at least one lock structure extends from a first end to an opposing second end, and defines an abutment face, an upper face opposite the abutment face, and a guide face opposite the base, and further wherein a geometry of the abutment face in extension from the first end to the second end differs from a geometry of the upper face in extension from the first end to the second end.

28. The reservoir system of claim 27 , wherein the upper face defines an insertion section extending from the first end and a locking section extending from the insertion section in a direction of the second end, and further wherein a major pl
