Abstract: A topical applicator of the propel/repel type includes a reservoir, an attachable applicator cap, and a metered dosing system. A housing has a dispense end and rotatable knob at an opposite end. The knob connecting to a screw and nut mechanism for elevating an elevator upward toward the dispense end. A component of the screw and nut mechanism exposed and extending out of at the bottom of the applicator for overriding the screw nut engagement allowing quick elevation of an elevator without rotation of the knob. The screw and nut mechanism having a platform for engaging the elevator when the screw and nut mechanism is in a fully retracted position providing stability for the elevator and visual indication of proper positioning and assembly of the applicator.

Abstract: A topical applicator of the propel/repel type includes a reservoir, an attachable applicator cap, and a metered dosing system. The reservoir is suitable for mixing a topical formulation of multiple constituents using an electronic mortar and pestle and is closed using the applicator cap. Alternatively, the reservoir may be prefilled with a ready-to-use cream and medicament formulation, then sealed with a removable seal. The topical applicator can also include a one-way ratcheting feature to prevent reverse movement (repel) of the metered dosing system. Metered doses can be dispensed through holes in the applicator cap by rotating a knob, which has detent positions that correspond to discrete doses, and which provides audible and tactile feedback.
