ABSTRACT:
A child-resistant, wick-based liquid emanation system includes a container which is capable of containing liquid and has an opening. A wick is partially disposed within the container and extends through the opening of the container. A hollow overcap encases the extended portion of the wick and has a closed, separable tip and an open base attached to cover the opening of the container. 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 disposed in the overcap between the tip and the base to retain the wick toward the base of the overcap. Alternatively, a protrusion from the wick can engage an inner surface 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.
