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.

1. An aroma generating miniature capsule attachable to the contoured surface of an incandescent light bulb to be activated by heat emanating therefrom, the capsule comprising: A. an envelope of flexible skin material defining an internal cavity bounded by a top wall having a vent hole therein and a base wall having a heat-resistant pressure-sensitive outer coating thereon, whereby the capsule may be adhesively attached to the bulb surface to conform thereto; and B. a pad of porous material impregnated with a volatile aromatic liquid supported within the cavity at a position adjacent the top wall to define an entrapped air pocket therebelow, whereby when the air in the pocket is heated and expanded by the heat emanating from the bulb, the resultant positive pressure forces the heated air through the pad to volatilize the liquid to produce an aromatic vapor which is discharged into the atmosphere through the vent hole. 2. A capsule as set forth in claim 1, wherein said skin is formed of synthetic plastic material. 3. A capsule as set forth in claim 1, wherein said skin is of polyester. 4. A capsule as set forth in claim 1, wherein said pad is of blotting paper. 5. A capsule as set forth in claim 1, wherein said volatile liquid is a perfume. 6. A capsule as set forth in claim 1, further including a peel-off cover on said top wall to seal the vent hole. 7. A capsule as set forth in claim 1, wherein said envelope is formed of a top section having a hat formation provided with an annular brim which is bonded to a disc-shaped base wall.
