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; and
said end wall spreading surface is an exterior surface presenting a generally polygonal configuration defined by five sides.

Abstract
A flexible, pressure-openable dispensing valve has a mounting base and has an outwardly extending head having at least three peripheral walls that each projects forwardly from the base. The head also includes an end wall that extends between, and connects, the outer margins of the peripheral walls. The end wall has a dispensing orifice surrounded by a spreading surface.

13. 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 flexible resilient material is silicone; said dispensing head extends over an interior volume that (1) is defined above said base, and (2) extends laterally beyond said dispensing orifice; said end wall has a generally planar exterior surface; and the maximum straight line distance across said end wall planar exterior surface from one edge of said end wall planar exterior surface to another edge of said end wall planar exterior surface is greater than about 50% of the maximum straight line distance between any two points on said base where said base joins said peripheral walls.
