Abstract
A foldable burner has a raised platform formed from aluminum foil portions and onto which fuel can be placed. Tabs are provided for gripping by a user to expand the burner from a collapsed condition to an expanded condition. Tabs may also act as supports to strengthen the burner and make the burner more stable. Apertures enable air to enter the burner under a chimney effect in order to provide oxygen to fuel for burning. The upper periphery of the burner provides support for a cooking vessel such as a saucepan. The burner is easy to transport in its folded condition. Further, it may be designed to offer a second use as transportation box.
Claims19
A portable collapsible stove, the stove being formed from sheet laminate material, the laminate material comprising at least one planar non-metallic substrate and at least one planar sheet of a metal material adhered to the substrate, the stove comprising a plurality of side walls formed from the sheet laminate material, the side walls being fastened together such that the side walls together define a tube, the tube having one end which comprises a base which rests in use on the ground and a second end which comprises a mouth to at least partially receive, and support, in use a container or the like, the stove further comprising a fuel support platform also formed from the sheet laminate material, the fuel support platform being located inside the tube at a position spaced from the base of the tube, the fuel support platform having an outer periphery which is fastened to the side walls, at least one air inlet aperture being provided in one of the side walls below the fuel support platform, at least one exhaust aperture being provided in one of the side walls above the fuel support platform, the stove being collapsible from an operational condition in which the side walls define the tube and the fuel support platform extends across the tube, to a collapsed, substantially flat condition in which the side walls and fuel support platform are substantially parallel to each other, the stove further comprising at least one aperture shield arranged to extend across each of the apertures to block light emitted through the apertures in use, the at least one aperture shield comprising a vent spaced from the aperture and operative to allow gas flow through the aperture.
A portable collapsible stove, the stove being formed from sheet laminate material comprising a planar non-metallic substrate having two opposite sides, and two planar sheets of a metal foil material each adhered to one of the opposite sides, the stove comprising a plurality of oblong walls formed from the sheet laminate material, the walls being joined together such that the walls together define a tube having two ends, one of the ends comprising a base which rests in use on the ground and the other of the ends comprising a mouth to at least partially receive, and support, in use a container or the like, the stove further comprising a fuel support platform also formed from the sheet laminate material, the fuel support platform being located inside the tube at a position spaced from the base of the tube, and having an outer periphery which is joined to the side walls inside the tube, at least one air inlet aperture being provided in one of the side walls below the fuel support platform, at least one exhaust aperture being provided in one of the side walls above the fuel support platform, the stove being collapsible from an operational condition in which the sidewalls define the tube and fuel support platform, to a collapsed, substantially flat condition in which the walls and fuel support platform are substantially parallel to each other.
A portable collapsible solid fuel stove, the stove being formed from sheet laminate material comprising a planar non-metallic substrate and at least one planar sheet of a metal foil material adhered to the substrate, the stove comprising a plurality of oblong walls formed from the sheet laminate material, each wall comprising a pair of side margins, the side margins of adjacent walls being stitched together such that the walls together define a tube having two ends, one of the ends comprising a base which rests in use on the ground and the other of the ends comprising a mouth to at least partially receive, and support, in use a container or the like, the stove further comprising a fuel support platform also formed from the sheet laminate material, the fuel support platform being located inside the tube at a position spaced from the base of the tube, the platform having an outer periphery which is stitched to the side walls inside the tube, at least one air inlet aperture being provided in one of the side walls below the fuel support platform, at least one exhaust aperture being provided in one of the side walls above the fuel support platform, the stove being collapsible from an operational condition in which the sidewalls define the tube and fuel support platform extends across the tube, to a collapsed, substantially flat condition in which the walls and fuel support platform are substantially parallel to each other.
A sheet of laminate material comprising at least one planar sheet of an metal foil material adhered, using fire retardant adhesive, to at least one planar non-metallic substrate, the resulting laminate sheet being fireproof such that the structural integrity of the resulting laminate sheet is stable when subject to flame temperatures of up to 1000° C., the resulting laminate sheet also being flame retardant such that the integrity of the resulting laminate sheet is stable when subject to repeated exposure to flames.
