Abstract

A candle-powered aroma generator in a lantern format housing a candle holder within a cylindrical container provided with a translucent shell mounted on a base and having a removable cover thereover whose roof has a central well. Below the bottom of the well is the burning wick of a candle supported in the holder, the candle flame heating the bottom which then functions as a miniature hot plate. Received in the well and resting on the hot plate is a replaceable aroma cartridge within whose cavity is a porous pad that partitions the cavity into upper and lower air chambers. The lower chamber is in heat transfer relation to the hot plate and the upper chamber has a vent therein. The pad is impregnated with a volatile liquid fragrance, and the heated air in the lower chamber produces a positive pressure therein which forces the air through the pad to volatilize the fragrance. The resultant vapor is discharged into the atmosphere through the vent.

Dependent claims

A candle-powered aroma generator in a lantern format comprising:

(a) a container housing a candle holder and provided with a removable metal cover having a depressed well therein which is positioned above the flame of a candle supported in said holder whereby the bottom of the well functions as a miniature hot plate;
and
(B) a replaceable aroma cartridge receivable in said well, said cartridge being formed with a metal base of good heat conductivity and a vented top wall, said cartridge having a cavity therein partitioned by a porous pad into a vented upper chamber and in an unvented lower air chamber, the metal base of the lower air chamber resting on said bottom of the well which functions as a hot plate and being in heat exchange relation with said hot plate, said pad being impregnated with a volatile liquid fragrance whereby air heated and expanded in the lower chamber produces a positive pressure which forces the hot air through the pad to volatilize the fragrance to produce a vapor in the upper chamber which is discharged into the atmosphere through the vent in the top wall of the upper chamber.

Dependencies are inferred from the claim text.
