Abstract:
1. A helix cup for use with a pressurized dispenser, said helix cup comprising: an inlet and an outlet defining a straight longitudinal axis and a convergent flow area therebetween, a funnel wall extending from said inlet to said outlet, said inlet having an inlet area, and said outlet having an outlet area, said inlet area being greater than said outlet area, and at least one portion being concave or convex in the longitudinal direction between said inlet and said outlet, said funnel wall having a surface area, said surface area being defined by the inequality: area:≠π×cone length×(inlet radius+outlet radius), wherein the inlet radius is greater than the outlet radius, cone length is the distance between the inlet and outlet taken along the funnel wall and is skewed relative to the longitudinal axis, Fl is the known constant of approximately 3.14, and further comprising at least one flow diverter disposed on said funnel wall, said flow diverter imparting a spiral flow component to fluid flowing from said inlet to said outlet, said flow diverter comprising at least one groove in said funnel wall.
