Title: Water closet additive means

Abstract: A device for introducing an additive liquid into a tank of a water closet. When the water closet is flushed and the water level in the tank lowers from a first normal level to a second lower level, air is admitted into conduit means. As the water level later rises from the second level toward the first level, the admitted air is forced through the conduit means into a container, containing an additive liquid, where it is compressed. The compressed air forces a portion of the additive liquid through conduit means and into the water in the tank.
