Abstract

A spray gun cup receptacle is disclosed comprising an open end for receiving a liner within a cavity and a base end opposite the open end. The sidewall comprises at least one aperture through which the cavity is visible from outside the spray gun cup receptacle. The apertures are divided one above the other by a brace member, at least a portion of which is disposed at a brace member angle α relative to the base plane. Also disclosed are receptacles comprising one or more tactile feedback members positioned adjacent an aperture.

First claim

What is claimed is:

1. A spray gun cup receptacle comprising
an open end for receiving a liner within a cavity;
a base end opposite the open end, the base end being positionable with respect to a work surface (W) with the open end facing upwards such that a base plane passing through the base end is parallel to the work surface;
a sidewall surrounding the cavity and connecting the open end to the base end, the sidewall comprising two apertures through which the cavity is visible from outside the spray gun cup receptacle, the two apertures being divided one above the other by a brace member, at least a portion of which is disposed at a brace member angle α relative to the base plane; and
a tactile feedback member positioned on the sidewall directly adjacent an aperture.

2. The spray gun cup receptacle of claim 1 wherein the brace member defines a brace member trajectory (T) about the cavity, the brace member trajectory comprising a non-circular ellipse.

3. The spray gun cup receptacle of claim 1 wherein the brace member angle α is at least 2 degrees.

4. The spray gun cup receptacle of claim 1 wherein the brace member angle α is less than or equal to 30 degrees.

5. The spray gun cup receptacle of claim 1 wherein the sidewall comprises one or more generally vertical support members intersecting the brace member.

6. A spray gun cup comprising
the spray gun cup receptacle according to claim 1 ; and
a liner positioned in the cavity, the liner comprising an open end corresponding to the open end of the spray gun cup receptacle.

7. The spray gun cup of claim 6 comprising volumetric indicia (V) positioned to be visible through the apertures and indicate a volume of contents of the liner.

8. The spray gun cup of claim 7 wherein the volumetric indicia are on the liner.

9. The spray gun cup of claim 7 wherein the volumetric indicia are provided on an insert positioned between the spray gun cup receptacle and the liner.

10. The spray gun cup of claim 6 comprising a lid member secured to the open end of the spray gun cup receptacle.

11. The spray gun cup of claim 10 wherein the open end of the liner is secured by interaction of the lid member and the open end of the spray gun cup receptacle.

12. A method of using a spray gun cup comprising
positioning the spray gun cup receptacle according to claim 1 on the work surface;
inserting the liner into the open end of the spray gun cup receptacle;
adding a liquid to the liner; and
viewing the level of the liquid through at least one of the two apertures in the sidewall of the spray gun cup receptacle.

13. The method of claim 12 comprising, prior to inserting the liner into the open end of the spray gun cup receptacle, inserting an insert comprising volumetric indicia into the open end of the spray gun cup receptacle.

14. The method of claim 13 comprising determining the volume of the liquid by viewing the volumetric indicia through the aperture.

15. The method of claim 12 comprising, after adding liquid to the liner, gripping the sidewall of the spray gun cup receptacle comprising the tactile feedback member directly adjacent the aperture; and using feedback from the tactile feedback member to avoid gripping the liner through the aperture.

16. The spray gun cup receptacle of claim 1 wherein the tactile feedback member comprises a protrusion extending radially-outwardly from the sidewall.
