ABSTRACT:
An adjustable dispenser tip including a nozzle forming a passage along a length of the nozzle. A plurality of independently movable, flexible fingers define an orifice at a dispensing end portion of the nozzle. A coupler is positioned about at least a portion of the nozzle and movable with respect to the nozzle to contact and urge the fingers to adjust an area of the orifice. An elastomeric web is positioned with respect to the nozzle and connects adjacent fingers. The elastomeric web can be positioned on an outer surface of the nozzle, an inside surface of the nozzle, or between adjacent fingers, for example.
