A refillable bottle for use in dispensing cleaning liquid into a toilet tank has openings at both ends, the bottle being installed in the tank by an integral hanger so that one opening, which is always above tank water level, is used for refilling the bottle in place in the tank with cleaning liquid and, being open after bottle installation, allows aerosols in the cleaning liquid to diffuse into the tank air so as to be forced from the tank by rising water in the tank to freshen the surroundings. The other opening has a dispensing valve mechanism mounted therein. Removable caps close the openings prior to installation. A float attached to a movable member of the valve mechanism actuates the mechanism so as to dispense a constant quantity of bottle liquid upon toilet flushing regardless of liquid level in the bottle or the refilling speed of the tank. The movable member has two oppositely disposed valve heads which mate with fixed valve seats formed in the valve mechanism.
