Abstract
Abstract A decorative lamp comprising a housing including a recess and a self-contained and replaceable mineral spirit burning lamp assembly disposed within the recess in the housing. The assembly comprises a cannister of mineral spirits into which a wick extends. A tubular portion is connected at the top of the cannister and has an open end. A cup-shaped cap member is snapped in place over the open end of the tubular portion and includes a pair of openings therein. A wick is folded in two with the folded mid portion extending outside the cap between the openings and with the free ends of the wick extending through the openings into the tubular member and therethrough into the cannister. The portion of the wick projecting out of the cap member serves as the flame site. The cap member also includes a pressure release port which is disposed adjacent to the openings through which the wick extends and is sufficiently large to permit the combustible fluid to seep therethrough as a result of the expansion thereof in the cannister when the cannister is fully filled, while small enough to preclude the fluid from gushing therethrough in the event that the cannister is inverted or otherwise knocked over.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
205 words
In a fluid burning lamp comprising a cannister of combustible fluid into which a wick extends, a top assembly for said cannister for holding a portion of said wick a predetermined distance away from said assembly to provide a flame site, said assembly comprising a tubular portion connected at the top of said cannister and having an open end and a cap member covering said end and including a pair of openings therein, with a web portion between said openings, said web portion including a projecting surface, said wick folded in two at a mid-portion thereof with said mid-portion extending outside said cap between said openings and with the free ends of the wick extending through said tubular member and into the fluid within said cannister, the projecting surface of said web portion supporting the top of said wick a predetermined distance from the cap member, said cap member also comprising a pressure release port disposed adjacent to said openings and being sufficiently large to permit fluid to seep therethrough in the event that said fluid expands to a volume greater than that of the cannister while being small enough to preclude fluid from gushing therethrough in the event that the cannister is knocked over.
Claim 2
Dependent Claim
205 words
In a fluid burning lamp comprising a cannister of combustible fluid into which a wick extends, a top assembly for said cannister for holding a portion of said wick a predetermined distance away from said assembly to provide a flame site, said assembly comprising a tubular portion connected at the top of said cannister and having an open end and a cap member covering said end and including a pair of openings therein, with a web portion between said openings, said web portion including a projecting surface, said wick folded in two at a mid-portion thereof with said mid-portion extending outside said cap between said openings and with the free ends of the wick extending through said tubular member and into the fluid within said cannister, the projecting surface of said web portion supporting the top of said wick a predetermined distance from the cap member, said cap member also comprising a pressure release port disposed adjacent to said openings and being sufficiently large to permit fluid to seep therethrough in the event that said fluid expands to a volume greater than that of the cannister while being small enough to preclude fluid from gushing therethrough in the event that the cannister is knocked over.
Claim 3
Dependent Claim
22 words
In the lamp of claim 2 wherein said cap member is cup-shaped and snaps over the open end of said tubular portion.
Claim 4
Dependent Claim
15 words
In the lamp of claim 2, said assembly additionally comprising automatic snuffer means coupled thereto.
Claim 5
Dependent Claim
