Having Absorbing, Baffling Or Additional Wick Supporting Structure In Container Patents (Class 431/323)
  • Patent number: 11378251
    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%.

  • Publication number: 20130216966
    Abstract: The present invention relates general to an alcohol burner that uses liquid alcohol as a fuel source and has an increased burn time, controlled combustion and a smaller footprint. In various embodiments, the present invention introduces a system of double stacked baffles with two separate functions. The upper baffle area optimizes controlled combustion, while the lower baffle area optimizes heat transfer from the combustion area down into the fuel storage area. The lower baffle also provides a steady vapor supply to the upper baffle area. By dividing these functions, the burner in accordance with embodiments of the present invention can store fuel vertically, rather than needing to be spread out horizontally. Embodiments of the present invention thus facilitate a wide range of practical configurations for consumer uses not previously possible.

    Abstract: This invention provides an improved chamber within the can of a canned heat product that allows more complete combustion due to a better mixing of air and gasified fuel which eminates from fuel on the surface of a fibrous fill. This improved mixing is the result of pulling cold outside air into the outer annulus of the combustion chamber where mixing occurs prior to ignition and also cools the fuel holding fiber as well as providing a steady height point of maximum temperature due to the combustion.

    Abstract: An oil burning lamp has a fuel reservoir, a fuel expansion chamber releasably and sealingly coupled to the fuel reservoir, a burner assembly coupled to the fuel expansion chamber, and an adjustable wick. If the fuel in the fuel reservoir undergoes thermal expansion, it flows into the fuel expansion chamber, thereby preventing fuel leaks and spills. In the preferred embodiment, the burner assembly is permanently coupled to the fuel expansion chamber, thereby preventing users from refueling the lamp while the lamp is burning. The fuel expansion chamber also serves as an overflow fuel chamber, so that if the lamp is inadvertently knocked over, the fuel will flow into the fuel expansion chamber, not out of the lamp.
