Abstract
A liquid fuel lamp which may be easily converted from a conventional beverage container. The liquid fuel lamp includes a container having a cylindrical wall connected to opposing top and bottom walls. The top wall includes an opening defined by a pair of side edges. A wick assembly is removably received within the opening in the top wall. The wick assembly includes a tubular metal sleeve supporting a substantially planar wick. Liquid fuel is received within the container wherein a lower portion of the wick is received in adsorbing contact with the liquid fuel. A stand is provided for supporting the container in an elevated position.
Claims15
A liquid fuel lamp comprising:
- a container having a cylindrical sheet metal wall defining a longitudinal container axis;
- opposing top and bottom sheet metal walls fixed to said cylindrical wall, said top wall including an opening extending substantially outwardly in a radial direction from proximate said longitudinal container axis, said opening formed by removal of a tear strip and defined by a pair of side edges spaced apart in a direction substantially perpendicular to said radial direction by a maximum distance do;
- a wick assembly received within said opening in said top wall, said wick assembly including a sleeve having a lower cylindrical portion and an upper tapered portion, said upper tapered portion having a substantially elliptical cross-section having a major dimension de, a substantially planar wick received within the sleeve and fixed to said upper tapered portion;
- and
- wherein said major dimension de of said tapered portion of said sleeve is greater than said maximum distance do of said opening, and said tapered portion of said sleeve deforms said side edges of said opening in a direction radially outwardly from said sleeve such that said top wall retains said wick assembly in a suspended position.
A liquid fuel lamp including:
- a container having a cylindrical sheet metal wall defining a longitudinal container axis;
- opposing top and bottom sheet metal walls fixed to said cylindrical wall, said top wall including an opening extending substantially outwardly in a radial direction from proximate said longitudinal container axis, said opening defined by a pair of side edges spaced apart in a direction substantially perpendicular to said radial direction by a maximum distance do;
- a wick assembly received within said opening in said top wall, said wick assembly including a sleeve having a lower cylindrical portion and an upper tapered portion, said upper tapered portion having a substantially elliptical cross-section having a major dimension de, and a substantially planar wick received within said sleeve and fixed to said upper tapered portion;
- and
- a stand for supporting said container in an elevated position.
A liquid fuel lamp comprising:
- a container having a cylindrical wall defining a longitudinal container axis;
- opposing top and bottom walls fixed to said cylindrical wall, said top wall including an opening extending substantially outwardly in a radial direction from proximate said longitudinal container axis, said opening defined by a pair of side edges spaced apart in a direction substantially perpendicular to said radial direction by a maximum distance do;
- a wick assembly received within said opening in said top wall, said wick assembly including a sleeve having a lower cylindrical portion and an upper tapered portion, a substantially planar wick received within said sleeve and fixed to said upper tapered portion, and an annular ring having an outer diameter dr and fixed to said sleeve above said opening;
- wherein said outer diameter dr of said annular ring is greater than said maximum distance do between said side edges and a lower surface of said annular ring engages said top wall for supporting said wick assembly within the container;
- and
- a stand including a vertically extending rod and a clip releasably supported by said rod, said clip including a securing leg and a connector biased toward said securing leg, said top wall of said container releasably secured intermediate said securing leg and said connector, said clip further including a support leg supported above said connector, said support leg and said connector including apertures for receiving said rod, wherein said support leg is biased away from said connector for frictionally engaging said rod.
