Definitions

  • the present invention is directed to a combustible heat source, and more specifically to a solid fuel package that controls a continuous burning of charcoal or other solid fuel and wherein the package is fully consumed by the flames.
  • Outdoor cooking is a popular recreational activity enjoyed by many while camping or day tripping, picnicking, tail gating at a sports event, or even in one's own back yard. While gas powered or electric grills may be used in one's own back yard or even while tail gating, a number of people prefer to use charcoal grills for cooking and/or grilling their meals whether at home, in a parking lot, at a campsite or other remote location for added flavor to the food, aroma, and for the experience. When grilling, it is preferable to be able to quickly and easily prepare the charcoal for cooking. It is also preferable to have easy clean up after food preparation is done - particularly if the cooking is done away from one's home.
  • Charcoal briquettes are commonly used to provide the heat necessary for cooking and/or grilling food on a grill.
  • Conventional charcoal briquettes are typically provided in a large bag from which a smaller amount must be taken and placed in the grill for use. The briquettes are quite messy and as such, it is desirable to minimize the physical handling of the briquettes.
  • a solid fuel package comprising a body formed of combustible material comprising at least one wall having a height and defining an interior space therein, said interior space having a first open end and a second open end distal from said first open end, a cover attached to said second open end further enclosing and defining said interior space, an amount of combustible solid fuel located inside said interior space and supported by said bottom cover, and a venting system, wherein the venting system comprises a plurality of elongated, substantially vertically oriented apertures spaced apart from each other around the exterior of said body.
  • FIG. 1 is a side perspective of a fuel igniter package incorporating an embodiment of the present invention
  • FIG. 2 is a front view of the package of FIG. 1;
  • FIG. 3 is a rear view of the package of FIG. 1 ;
  • FIG. 4 is a side perspective view of the package of FIG. 1 further depicting a top lid;
  • FIG. 5 is a side view of the package of FIG. 1 ;
  • FIG. 6 is a top view of the package of FIG. 1 ;
  • FIG. 7 is a bottom view of the package of FIG. 1 ;
  • FIG. 8 is a cut-away view of the bottom side portion of the package of FIG. 1 , taken along line 8-8 of FIG. 5;
  • FIG. 9 is a cut-away view of the package of FIG. 1 depicting the solid fuel contained therein.
  • Fuel package 10 for a fuel source 12.
  • Fuel package 10 includes a body 11 having side wall 14, a bottom cover 20 and a venting system 22.
  • Body 11 preferably comprises a tubular shape formed by side wall 14 that defines a compartment 13 having an interior space.
  • Body 11 has a diameter P D , a length P L , a base end 16 and a top end 18 distal from the base end 16. The diameter is generally the same at the base end 16 and the top end 18.
  • the compartment is large enough to store a predetermined quantity of charcoal briquettes or other solid fuel.
  • body 11 is formed of more than one side wall, rather than have a continuous tubular construction, wherein the plurality of side walls are connected to form a structure defining a compartment therein.
  • Body 11 is made of paper material, such as cardboard, paperboard, wound paper, pulp paper or the like, or other combustible material known in the industry.
  • the preferred material is also preferably fire-resistant to a degree sufficient to allow body 11 to maintain its structure while the solid fuel 12 burns to a desired degree sufficient for grilling/cookiiig food, at which point body 11 will be consumed and collapse, leaving the solid fuel 12 ready for use in grilling.
  • side wall 14 preferably comprises a bottom lip 21 located at the base end 16 of body 11. Bottom lip 21 folds under toward the interior of compartment 13 to provide a double layer of body 11 for additional thickness and strength at base end 16.
  • body 11 former comprises a bottom cover 20 for supporting the solid fuel 12 within the interior compartment 13 defined by side wall 14 and bottom cover 20.
  • Bottom cover 20 is made of the same material as body 11 and is preferably paper in nature or an alternative combustible material.
  • Bottom cover 20 is attached to base end 16 of body 11 by any of numerous methods commonly used in the industry.
  • bottom cover 20 comprises a flange 23 located along the exterior edge which is located in between the two layers of body 11 formed by bottom lip 21.
  • Such methods of attachment include but are not limited to friction fit, adhesive attachment, stitching or any method whereby the attachment material is fully consumed during the burning of the body 11 and the solid fuel 12.
  • Venting system 22 provides the necessary oxygen to the solid fuel 12 for ignition and burning.
  • Venting system 22 comprises a plurality of substantially parallel, elongated venting apertures 24 arranged vertically around the exterior of side wall 14.
  • Apertures 24 each comprise a top end 26 located on the end nearest the top end 18 of body 11 and a bottom end 28 located on the end nearest the base end 16 of body 11.
  • Each aperture 24 further comprises a width Vw and a length V L .
  • apertures 24 For strength of the body 11 and ability of the body 11 to resist combustion long enough for the solid fuel 12 to reach the desired state for grilling, it has been found preferable for apertures 24 to be located approximately 2 to 3.5 inches apart from each other, and more preferably approximately 2.5 to 3 inches apart from each other, although other distances are acceptable. As such, as the diameter of body PD increases, additional apertures 24 may be added to provide adequate ventilation for the ignition of the solid fuel 12, while still maintaining the necessary structural integrity of the body 11 to support the solid fuel 12 and retain sufficient structure for the time necessary for the solid fuel 12 to reach the desired state for grilling.
  • a body 11 having a diameter PD of 4 inches would preferably comprise approximately 4 venting apertures 24.
  • a body 11 having a diameter PD of 6 inches would preferably comprise approximately 7 venting apertures 24.
  • venting aperture 24 area is preferably approximately 4 to 12% of the non-vented body 11 surface area and more preferably 7 to 8%.
  • a preferred venting aperture width Vw is approximately .2 to .3 inches, and more preferably .25 inches, but could vary depending on the combustibility of the material used for body 11, which may in turn depend on the specific type of material as well as the thickness of the material.
  • a preferred venting aperture length is approximately .5 inches less than the height of side wall 14, although the length could vary between .42 and 2 inches depending on the type of paper used for the body 11 and could vary more widely if materials other than paper were used.
  • vent top end 26 and body top end 18 If the distance between vent top end 26 and body top end 18 is too small, body 11 will collapse before the solid fuel 12 has reach the desired state for grilling. Conversely, if the distance between vent top end 26 and body top end 18 is too large, body 11 will not collapse early enough for use of the solid fuel 12 and/or full consumption of body 11.
  • the distance provided between venting aperture 24 and the edge of body 11 at body top end 18 is substantially equal to the distance provided between venting aperture 24 and the edge of body 11 at body base end 16. As the combustibility of the material increases, the overall size of the venting apertures in relation to the overall surface area of body 11 would preferably decrease to adjust for the increased speed of combustion and ensure that the structure remained sufficiently intact until the solid fuel was at the desired state.
  • venting apertures 24 may be curved, squared, or oilier shapes capable of manufacture in the industry, keeping in mind ease and feasibility of manufacture.
  • the shape of venting apertures 24 is preferably an elongated slit as shown in FIGS. 1-3, for ease of manufacture. It is within the scope of the present invention, however, for the shape of venting apertures 24 to be elliptical, oval, or other shapes, provided any increase in venting aperture area is taken into account in determining the appropriate number and size of apertures to include in body 11. It is also within the scope of the present invention for the apertures to comprise multiple shorter apertures in a single column as opposed to a single, continuous aperture.
  • side wall 14 at body top end 18 may comprise a rolled lip (not shown) to provide additional structural and additional surface area for attaching optional lid 30.
  • An embodiment of the present invention comprises a lid 30 covering body top end 18 to assist in retaining solid fuel 12 within compartment 13 during transport.
  • Lid 30 may be made of plastic, paper, or other material such as aluminum foil.
  • Lid 30 may be removably attached to body 11 by a friction fit, by adhesive (as shown in FIG. 4) or by other means commonly known and used in the packaging industry.
  • Lid 30 may have a shape to match the shape of the top end 18 of body or may include corners or a tab extending past the edge of top end 18 to allow for easy removal.
  • fuel package 10 is placed in a grilling unit in an upright orientation with base end 16 on the bottom.
  • the lid 30 is removed either before placing package 10 in the grilling unit or after.
  • the solid fuel 12 is ignited by user with a match or lighter through the top opening 19 located at top end 18.
  • the venting apertures 24 allow for the desired air flow through the body 11.
  • the paper shell of body 11 burns down to the base end 16 and the sold fuel will collapse down on itself forming a uniform pile.
  • the solid fuel preferably charcoal briquettes, are ready for cooking when the paper body 11 is burned away.
  • a user could apply an accelerant to the solid fuel. Once the user is done cooking, only ash remains with no paper, metal or other refuse to discard.
