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, as for example, one constructed of a pair of concentric frusto-conical plastic containers dimensioned to fit closely, but rotatably one within the other. The top end of the inner container is closed by a transverse wall from which projects upwardly a plastic simulated horticultural item, such as a flower. 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.
