Title: Double-cone candle shade

Description:
1. FIELD OF THE INVENTION 
     This invention is in the field of heat and light shades, specifically candle shades. 
     2. BACKGROUND OF THE INVENTION 
     A jar candle that is burned for the first time must be “set”. That is, it must burn long enough for the wax to liquify across the width of the entire vessel. Otherwise, subsequent burns melt only as far as the first burn, leading to candle “tunneling”. 
     3. DESCRIPTION OF RELATED TECHNOLOGY 
     A well-known remedy to help a candle set more quickly is to cover it with a “tent”, a funnel made of tin foil or aluminum foil. The foil reflects heat back to the candle, while a hole at the top allows smoke and gas to escape. 
     4. SUMMARY OF THE INVENTION 
     The present invention, the “Candle Collar”, is a double-layered candle tent. It is a durable, reusable product rather than a makeshift aluminum foil creation. 
     The Candle Collar is a multi-function product marketed to true candle enthusiasts. It is designed to be placed over the top of a candle jar, with three main functions. The primary function is to trap in the heat produced by the candle, allowing an even distribution of heat inside the candle/collar, ensuring that the candle fully liquifies across the entire width of the vessel, eliminating Candle Tunneling, and allowing the candle to “set” in approximately 60% less burn time than without the Candle Collar. As a second benefit, the Candle Collar makes the presence of a burning candle vastly safer when in the presence of pets or children, many of which are curious and risk injury and are often at “candle surface height” such as a table or dresser. Finally, the frequent use of a Candle Collar will reduce overall risk of any open flame burning in an open space. The Candle Collar sits securely and is held steadily with internal silicon bands.

     6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     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. 
     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&#39;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. 
     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. 
       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. 
     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.
