Abstract:
A screw operated applicator for incremental dispensing comprising:a tubular body including an open dispensing end and a base wall having at least one hole through the base wall;a threaded movable support inside said tubular body, said support being in contact with an inner wall of said tubular body so as to prevent rotation of the support in the body;a rotatable dispensing screw including a control member disposed adjacent said base wall, a raised portion including at least one protrusion, a snap member and a threaded shaft extending through said hole in the base wall into said tubular body and along a substantial length of said tubular body, said threaded shaft being threadably engaged with said support; wherein said base wall includes an inner wall surface of a non-circular configuration which surrounds in use said raised portion of the dispensing screw such that said at least one protrusion interacts with said inner wall surface to provide resistance to turning of said control member and to create at least two favored control member orientations; and wherein said rotatable dispensing screw rotates to cause said support to move up or down in relation to said tubular body based on direction of turning of said control member.
