1. A nozzle for dispensing a viscous material from a source of said material, said nozzle comprising:
- a generally rectangular dispensing orifice;
a nozzle throat in flow communication with said nozzle orifice; and
a transition in flow communication with said nozzle throat and said source of said material;
whereas said source comprises a container having an interior cross-sectional area at the interface of said source and said transition of A, said transition having a cross-sectional area at the interface with said nozzle throat of B, said dispensing orifice having a cross-sectional area, in a plane perpendicular to flow through said orifice of C, where;
A is in the range of from 2 to 3 of B, and B is in the range of from 25 to 30 of C.
