Patent ID: 8882496

Claim:
A container candle having improved burn performance and fragrance delivery comprising: a non-meltable outer container having an open top in use, side walls and a bottom wall; a non-cylindrical insert wherein an upper portion of the insert is narrower in diameter than diameter of a bottommost portion of the insert, said insert having a top wall which transitions into tapered side walls which in turn transition to a base with a bottom surface, said bottom surface being essentially parallel to an uppermost outer surface of the top wall of the insert, wherein the non-cylindrical insert has a height which is less than the height of the container, the base has a diameter which is less than an inner diameter of the bottom wall of the container but is sufficient in diameter to cause said non-cylindrical insert to become auto-centered on the bottom wall of the container when placed thereon in the container, and said non-cylindrical insert comprising at least one combustible fuel; a wick extending centrally through the non-cylindrical insert with an upper portion of the wick extending beyond the top wall of the non-cylindrical insert; and a fill material comprising at least one fragrance and at least one combustible fuel, said fill material being situated in said container around said non-cylindrical insert without air pockets formed therein in an amount sufficient to at least substantially cover the non-cylindrical insert but not cover said upper portion of the wick extending out of the insert and be below a top edge of the side walls of said container; wherein based on shape and positioning of said insert, retention of combustible fuel within the container upon end of life of the wick is less than about 10 wt. % based on 100 wt. % being a sum of said combustible fuel of said fill material and said combustible fuel of said insert, and wherein based on said shape and positioning of said insert, said fill material avoids a tunneling effect upon burning thereof.
