<p>A shroud is detachably engaged around the neck of a light bulb and is detachably sealed to the bulb at this point so that it is leakproof. The shroud extends upwardly around the bulb and is spaced therefrom. Liquid or crystal fragrance, deodorant, insecticide or the like is poured into the lower portion of the shroud surrounding the light bulb so that when lit, the heat from the bulb vaporizes the liquid or crystals and the vapor is dispersed from the open upper end of the shroud by convection air currents. An elastomeric O-ring is in wedging contact between the lower end of the light bulb and the lower end of the shroud immediately above the sealing material in order to protect the sealing material from liquids within the shroud.</p> |
