A fluent material dispensing apparatus for use with a container having fluent material therein, and means for selectively applying pressure to the fluent material, comprising an elongated tubular body, means for connecting one end of said body to the container in a manner to receive fluent material

A fluent material dispensing apparatus for use with a container having fluent material therein, and means for selectively applying pressure to the fluent material, comprising an elongated tubular body, means for connecting one end of said body to the container in a manner to receive fluent material therefrom, an intermediate portion and a tip portion integrally connected to the other end of said body, said tip portion having a side wall with at least one opening therethrough, an elastomeric band of predetermined thickness encircling said side wall of said tip portion and normally closing said opening, and a cap having side walls and a discharge opening mounted on said intermediate portion and in spaced relationship with said tip portion, whereby pressure applied to the fluent material causes the elastomeric band to expand and permit fluent material to flow from said tip portion and said cap, and wherein the space between the outer surface of said elastomeric band and the inner surface of said cap side walls is less than the thickness of said band.
