Abstract
A paint bell cup for directing a spray of paint onto a surface includes a cup body having an outer surface, an inner conical surface having a circumferential edge, and a stem extending from the outer surface. The stem includes a passage that delivers paint toward the inner conical surface. The cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge. The one or more spray control features promote a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge.

A paint bell cup for directing a spray of paint onto a surface comprising:
- a cup body having an outer surface,
- an inner conical surface having a circumferential edge, and
- a stem extending from the outer surface, the stem including a passage that delivers paint toward the inner conical surface,
- wherein the cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge, the one or more spray control features promoting a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge,
- wherein the one or more spray control features include grooves formed on the inner conical surface, the grooves extending along the inner conical surface toward the circumferential edge, and
- wherein the grooves extend from the stem across the inner conical surface and up to the circumferential edge.
