Abstract
A screw operated stick applicator providing for controlled dispensing of a product in predetermined increments based on a click action mechanism. A tubular body holds a supply of product, which is dispensed by the action of a dispensing screw having a control member adjacent the base wall of the tubular body and a threaded shaft inside the body. The shaft is threadably engaged to a movable product support. Protrusions on the dispensing screw interact with the base wall of the body to provide resistance to the smooth rotation of the control member and cause the control member to favor certain predetermined positions. The base wall includes an inner wall surface at its lower end which interacts with the protrusions to provide click action and, thus, controlled incremental dispensing.
