Abstract
Abstract A decorative room air treating device in the shape of a flower pot or other aesthetically appealing container having a body portion with circular cross-sections, which might comprise a single-walled container capped by a fixed orificed circular disc and a coaxially rotatable disc having orifices which, in a certain angular disposition, may be brought into registry with the orifices in the fixed disc, alternatively, the device might comprise a pair of cylindrical containers dimensioned to fit closely, but rotatably one within the other. A cake of an air treating substance is disposed within the inner container and the side walls of the two containers are so orificed that in one rotational position relative to each other, none of the orifices of the two containers fall into registry, but in a second rotational position, they are disposed in registry. In positions intermediate the two extremes, the orifices of the two containers may be disposed in various degrees of registry. Means may be provided at opposite ends of the two containers to enable them to be rotated relative to each other.
