Abstract

A scent-bearing ring adaptable for at least semi-permanent engagement with the neck of an incandescent bulb that generates both light and heat. The ring comprises an annular body having an inner layer formed to engage the bulb neck and an outer layer containing a scent or vapor-releasing agent actuable by heat. The inner layer is formed from a moldable material at least capable of resisting without substantial damage the heat generated by the bulb when the bulb is operated in a base-down position and capable of transferring the heat to the outer layer, the outer layer being moldable and porous.
