Double-cone candle shade

Abstract

A candle shade is adapted to fit securely atop a candle vessel. The shade assumes the form of a double conical frustum. An interior shell makes direct contact with the candle vessel. The interior shell reflects radiative heat back to the candle surface while allowing smoke and gases to vent upward. Ideally, it is constructed from aluminum sheet metal and includes a band near the lower opening for an airtight seal. An exterior shell encloses the interior shell. The exterior shell protects the outer environment from the heat of the flame, especially so that the shade can be handled safely. Insulation is aided by handles on the exterior shell. Spacers affixed to the interior shell also create an insulating air space between the interior and exterior shells. The double-cone candle shade reduces candle “set” time by 65%.

Claims

1. A shade for a candle vessel, comprising: an exterior shell substantially in the shape of a conical frustum, comprising an exterior shell upper opening and an exterior shell lower opening; an interior shell substantially in the shape of a conical frustum similar to and smaller than the exterior shell, seated inside the exterior shell and comprising an interior shell upper opening and an interior shell lower opening; a plurality of spacers attached to the interior shell; an insulating space between the interior shell and the exterior shell, as a result of the spacers; and handles affixed to the exterior shell.

2. The shade of claim 1, further comprising a band of non-slip, non-flammable material affixed to the interior shell in proximity to the interior shell lower opening; and wherein the interior shell is constructed from two-ply aluminum sheet metal; the exterior shell is constructed from a plastic resin compound; and the insulating space has a width between 1.5 mm and 2.5 mm.

3. The shade of claim 1, further comprising a band of non-slip, non-flammable material affixed to the interior shell in proximity to the interior shell lower opening; and wherein the interior shell is constructed from two-ply aluminum sheet metal; the exterior shell is constructed from a material selected from the group consisting of glass and ceramic; and the insulating space has a width between 1.5 mm and 2.5 mm.

Description

5. BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows the invention in place atop a candle jar. The exterior shell is visible.

(2) FIG. 2 shows the interior shell.

(3) FIG. 3 depicts the interior shell fitted into the exterior shell to create a double-cone structure.

(4) FIG. 4 is an exploded view showing the exterior shell, interior shell, and band.

6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) The Candle Collar has two main components: an exterior shell 10 and an interior shell 20. The exterior shell is seen best in FIG. 1, which shows the invention in place atop a candle vessel 11. The exterior shell is an overlay in the shape of a conical frustum. It is ideally made of a non-flammable plastic resin compound. It may alternatively be made of ceramic or glass. The exterior shell has an exterior shell upper opening 101 and an exterior shell lower opening 102. The main purpose of the exterior shell is to shield the environment from the heat of the candle flame. For additional safety, handles 103 may be attached to the exterior shell. The outer shell is decorative and may be personalized to blend in seamlessly with the decor.

(6) The interior shell 20 is shown in FIG. 2. It is also shaped as a conical frustum. The interior shell is ideally made of two-ply aluminum sheet metal joined at a seam 205. The seam may be soldered, glued, or riveted. The interior shell has an interior shell upper opening 201 and an interior shell lower opening 202. The main purpose of the interior shell is to reflect the candle flame's heat back to the candle. A secure, air-tight fit is important. This fit is facilitated by a band 203 of non-slip/non-flammable material on the inside lower lip of the interior shell.

(7) It is important to maintain an insulating space 31 between the interior shell and the exterior shell so that the interior shell can reflect heat back to the candle while the exterior shell shields the outer environment from the heat. See FIG. 3. A gap of roughly 2 mm is ideal. This gap is maintained with a plurality of spacers 204 secured to the interior shell.

(8) FIG. 3 illustrates the interior shell 20 in position nested inside the exterior shell 10. As a whole, this device would be inverted and then positioned atop the candle vessel as seen in FIG. 1. Refer to FIG. 4 for an exploded view.

(9) Experimentation has shown that the Candle Collar helps candles set significantly more quickly than tents improvised from aluminum foil or tin foil. Candles covered by the Candle Collar set in roughly ⅓ of the time required for candles covered by aluminum foil funnels.
