ABSTRACT:
An aroma-generating miniature capsule adhesively attachable to the surface of an incandescent light bulb to be activated by heat emanating therefrom. The capsule, preferably formed of a flexible synthetic plastic skin, includes a top wall having a vent hole therein and a base wall provided with a pressure-sensitive outer coating to adhere the capsule to the bulb. Supported within the internal cavity of the capsule is a pad of porous material having good wicking properties impregnated with a volatile aromatic liquid. The pad is at a position within the cavity adjacent the top wall to define therebelow an air chamber which when heated creates a positive air pressure forcing a stream of heated air through the pad to produce a vaporous scent. This is discharged into the atmosphere through the vent hole.
