What is claimed is: 1. A dispensing valve comprising:(A) a mounting base; and(B) flexible, resilient material defining a dispensing head extending outwardly from said base, said dispensing head including(1) at least three peripheral walls that each projects outwardly from said base and that each defines an outer margin; and(2) an end wall that(a) defines a dispensing orifice;(b) defines a spreading surface around said orifice;(c) extends between, and connects, said outer margins of said peripheral walls; and(d) is oriented to present said spreading surface extending from a first location to a second location that is further outwardly from said base than is said first location; and whereinsaid dispensing head peripheral walls include(1) two converging forward side walls;(2) two rearward side walls each extending rearwardly from one of said forward side walls and toward each other; and(3) a back wall between, and joining, said rearward side walls; and whereineach said forward side wall, each said rearward side wall, and said back wall have at least a portion defining a generally planar exterior surface; andsaid end wall spreading surface is an exterior surface presenting a generally polygonal configuration defined by five sides.
