A child-resistant, wick-based liquid emanation system includes a container (30) which is capable of containing liquid and has an opening (36). A wick (50) is partially disposed within the container (30) and extends through the opening (36). A hollow overcap (101) encases the extended portion of the wick and has a closed, separable tip (100) and an open base (200) attached to cover the opening. The system is activated by separating the tip from the overcap. A retainer may be provided for obstructing complete removal of the wick from the container through the overcap after the tip is separated from the overcap. The retainer can include a shoulder (300) disposed in the overcap (101) between the tip (100) and the base (200) to retain the wick (50) toward the base of the overcap. Alternatively, a protrusion (53) from the wick can engage an inner surface (225) of the overcap or the container. In this case, the overcap can have a frangible portion facilitating separation of the tip, and the wick can extend past the frangible portion toward the tip.
