Abstract:
A venting apparatus (20) for improving the stability and efficiency of the combustion flame of a containerized candle that includes a fuel source burnt in the flame, a wick and a vessel (10), which defines an interior thereof for enclosing the wick and fuel source and has an open mouth, and where the vessel includes sidewalls (12) that terminate in a brim (14) at the open mouth of the vessel,the venting apparatus comprising: a flat top (22) shaped and dimensioned to cover the open mouth (15) of the vessel (10) and extend over the brim, the top having an exhaust vent (23) therein for venting a flow of exhaust air from the vessel interior, a plurality of feet (28) extending downward from the top for spacing the top above the brim when the venting apparatus is seated atop the vessel to permit a flow of inlet air between the top and the vessel brim, and an annular baffle (24) extending downward from the top between the plurality of feet and the exhaust venting means so as to extend partially downward into the open mouth of the vessel and to seat adjacent the brim of the vessel when the apparatus is seated atop the vessel, the baffle constitutes means for directing the flow of inlet air downward along the sidewalls of the vessel and for separating the flow of inlet air from the flow of exhaust air, the baffle having a plurality of longitudinal inlet channels (25) radially spaced along the periphery of the baffle so as to form inlet openings through which inlet air may enter the vessel interior, the plurality of channels constituting means for columnating the flow of inlet air into a plurality of distinct and radially spaced and separated air flow columns within the vessel interior.
