Abstract
Described is a single function or multi-function device for attachment to the tank of a toilet fixture. The device provides a diffusible air-treatment concentrate for deodorizing or otherwise treating the ambient air surrounding the toilet. At the same time, the multi-function device provides a water-soluble water-treatment concentrate for treating the flush water stored in the toilet tank. The device can have an air moving part with a delay value to increase fragrance delivery. The device can have an air treatment part with a reservoir having fragrance containing particles. The reservoir can have an attachment means so that it can be replaced when the fragrance is used up. The device can deliver a burst of fragranced air during a toilet flush cycle.
