Abstract
Abstract A disinfectant, deodorizer and/or colorizer device for mounting in a toilet flush tank, comprising a covered container provided with a tubular member communicating with the container and having an open upper end extending above the top of the container and the water level in the flush tank for reception of disinfectant, deodorizer and/or colorizer chemicals which may be in tablet or other form. The tubular member is closed by a stopper having a hole therein through which extends a rod for pushing the chemical downwardly for passage into the water container. Filter means cover air and water inlets and outlets in the container cover to prevent passage of undissolved colorizer particles out of the container. Hanger means are provided for mounting the container in the flush tank.
