DEFINITION

Classification: 239/34

(under the class definition) Apparatus having means to disperse or spread material out into the ambient air by

vaporization from an open container or holder, capillary porous or wick type feed means, by mere drip through the air or by sublimation, all such media being merely exposed to the ambient air and without the use of draft producing means.

(1) Note. This is the generic subclass for holders for slow diffusers and for volatilization of liquid saturated sorbents by mere ambient air desorption. See class definition, "Lines With Other Classes, Slow Diffusers," for lines between Classes 96, 239 and 261 in regard to this type of subject matter. For solid sorbent apparatus for gas separation, see Class 96, Gas Separation: Apparatus, subclasses 108+.

(2) Note. In general, the combination of a slow diffuser and an art device is classified with the art device. See the example Class 312, Supports: Cabinet Structure, subclasses 31+ for containers combined with slow diffusers.
