Claim:
A flowable edible material mass progressive dispenser comprising in combination: a) a container for said mass, said container having an end wall, b) a nozzle projecting generally forwardly from said end wall, and having a side wall that extends forwardly and terminates at a furthest forward end opening through which said mass is dispensed, c) said end opening defining a periphery having a lateral width dimension and a height dimension, said lateral width dimension substantially exceeding twice said height dimension of said end opening, for spreading the mass of material being dispensed, the dispenser having surfaces including arcuate and concave surfaces at widthwise opposite ends of said opening, which remain of fixed dimension, and d) said nozzle side wall having a peripheral outer surface comprised of an upper wall, a lower wall and two sidewalls, wherein the entire exposed portion of at least the upper wall and the lower wall of said peripheral outer surface comprises a concave surface positioned between two convex surfaces, at least one of the convex surfaces of each of the upper and lower walls terminating at the opening and having substantially the same convex curvature, e) whereby a substantially constant height layer of said mass is dispensed forwardly through said nozzle end opening as the mass in the container is pressurized, and said layer has the width of said end opening.
