ABSTRACT:
A long-life aroma-generating miniature capsule attachable to the surface of an incandescent light bulb to be activated by heat emanating therefrom. The capsule is constituted by a flexible pad of porous material impregnated with a volatile liquid fragrance, the pad being sandwiched between base and cover plies formed of a metal foil-plastic laminate peripherally joined together to create an envelope whose cavity is occupied by the pad. The cover ply has a vent hole therein, and the outer surface of the base ply is coated with a layer of pressure-sensitive adhesive, whereby the capsule may be conformed and adhered to the contoured surface of the light bulb. The adhered capsule is in heat transfer relation to the bulb, as a consequence of which the liquid impregnant is volatilized to produce an aromatic vapor that is discharged through the vent hole. The metal foil in the envelope acts as a heat radiator to dissipate the heat transferred thereto to a degree reducing the rate of volatilization to a level at which the capsule remains effective as an aroma generator for a prolonged period before the liquid is exhausted.
