Full Description:
FIELD OF THE INVENTION 
     The present invention is directed generally toward fire starting assemblies and, more particularly, toward a portable fire starting assembly having easy lighting and long burning characteristics. 
     BACKGROUND OF THE INVENTION 
     Outdoor recreational activities are common in today&#39;s society. Such outdoor recreational activities include activities such as camping, fishing, hunting, sledding, and virtually any other activity that can be performed outdoors. Various of these activities, e.g., sledding, are not performed during the summer months when the weather is warm. Many individuals engage in such outdoor activities when the outdoor temperature is on the colder side. For example, the rifle deer season in the Commonwealth of Pennsylvania typically occurs from late November to mid-December. At such times, the outdoor temperature can be fairly cold, potentially reaching frigid temperatures with and without factoring in wind chill. Also, the opening day of trout season in the Commonwealth of Pennsylvania typically occurs in mid-April. At this time, the weather is often on the colder side, requiring individuals to take appropriate precautions to keep themselves warm. Even during the summer months, the temperature at night may drop considerably from the temperature during the daylight hours. This is especially true in the mountainous areas of the country where individuals typically go camping. 
     Many individuals engaging in outdoor activities in the colder months of the year will be become just that, cold. Unless these individuals can find a way to warm themselves, even if only for a short period of time, the fact that they are cold may cause them to cut short the outdoor activity in which they are engaging. At such times, many individuals desire to light a fire, such as a campfire, to warm themselves. However, campfires are fairly difficult to light, requiring an individual to take the time to gather wood and kindling, and also requires the individual to have on their person, or readily available, a flammable starting material in order to get the fire started. Further, simply gathering wood and kindling in general is not enough to build a campfire, as the wood and kindling must be sufficiently dry in order to burn properly. Since an individual by this time is normally already cold, he or she may not wish to take the time to search for and gather sufficiently dry wood and kindling, and simply forego in continuing to engage in the particular outdoor activity. 
     Even after searching for and gathering sufficiently dry burning materials, an individual may find it difficult or impossible to start a campfire due to windy conditions. The wind may continue to extinguish the fire before it has a chance to sufficiently burn and “catch”. Thus, even though an individual has taken the time to gather the appropriate wood, kindling, etc., a windy day may simply prevent the individual from being able to light a fire for warmth. This can be particularly frustrating and, when faced with such problems, often cause an individual to simply quit the outdoor activity and return to a car, house, etc., where heat is available. 
     The present invention is directed toward overcoming one or more of the above-mentioned problems. 
     SUMMARY OF THE INVENTION 
     A fire starting assembly is provided in accordance with the present invention for easily lighting and maintaining a fire in an outdoor environment. The inventive fire starting assembly includes, in its simplest form, a combustible container defining an interior, and intermixed layers of flammable and combustible materials in the container interior having first and second burning points, respectively. To provide oxygen for the fire, the container includes holes for admitting air into the container interior, thus fueling the fire within the container interior. 
     The first burning point of the flammable material is at a temperature less than the second burning point of the combustible material. The combustible container typically has a third burning point at a temperature between the first and second burning points.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIG. 1, a fire starting assembly according to the present invention is shown generally at  10 . The fire starting assembly  10 , in its simplest form, includes a combustible container  12  defining an interior  14 , with a flammable material  16  generally filling the container interior  14  and having a plurality of combustible members, or material  18 , intermittently dispersed in the flammable material  16  in the container interior  14 . As shown in FIG. 1, the flammable  16  and combustible  18  materials are provided in intermixed layers within the container interior  14 . 
     The combustible container  12 , the flammable material  16  and the combustible members  18  are all made from burnable material. In order to facilitate lighting and burning of the fire starting assembly  10 , the flammable material  16  includes an easy ignitable material having a burning point at a relatively low temperature. The combustible container  12  is made of a material that is longer burning than the flammable material  16 , and has burning point at a temperature higher than the burning point temperature of the flammable material  16 . The combustible members  18  are made of a material that is even longer burning than the combustible container  12 , and each has a burning point at a temperature higher than that of the burning point temperatures of either the combustible container  12  or the flammable material  16 . In a preferred form, the combustible container  12  includes a cardboard box, the flammable material  16  includes shredded paper, and the combustible members  18  includes pieces of wood, and these elements will hereinafter be referred to as such. However, it should be understood that other burnable materials having appropriately related burning point temperatures for at least the flammable  16  and combustible  18  materials may be implemented without departing from the spirit and scope of the present invention. 
     Referring to FIGS. 1-2, the cardboard box  12  is preferably rectilinear in shape, having top  20 , bottom  22 , and four side surfaces  24 . To facilitate opening of the cardboard box  12  for lighting purposes, the top surface  20  is defined by flaps  26  which may be folded as shown in FIG. 2 to define the top surface  20 , thus closing the cardboard box  12 . To maintain closure of the cardboard box  12 , a strip of tape  28 , or other adhesive means, may be provided along the top surface  20  along the seam formed by the closed flaps  26 . The tape  28 , or other adhesive means, should maintain the cardboard box  12  in a closed position, but be removable so that the flaps  26  may be opened for lighting of the fire starting assembly  10 . 
     To facilitate burning of the shredded paper  16  and the wood pieces  18  within the container interior  14 , air holes  30  are provided in the side surfaces  24 . Preferably, the air holes  30  are approximately 1.25″ in diameter, with two air holes  30  formed in each of the side surfaces  24  generally near the bottom surface  22 . However, any number of air holes  30  having virtually any diameter may be formed in the fire starting assembly  10  in any of the surfaces  20 ,  22  or  24  without departing from the spirit and scope of the present invention. To facilitate carrying of the fire starting assembly  10  to a remote location, handles  32  are provided in opposing side surfaces  24 . Preferably, the handles  32  typically include cut-out handles formed in the opposing side surfaces  24 , however, other handle configurations may be implemented. 
     As shown in FIGS. 1 and 3, the pieces of wood  18  are preferably elongate, having first  34  and second  36  spaced ends. The wood pieces  18  are intermittently disposed in the container interior  14 , such that a space is provided around each of the wood pieces  18 . As shown in FIG. 1, the wood pieces  18  are preferably oriented in row and column format within the container interior  14 , such that adjacent wood pieces  18  in each row are spaced from one another, and adjacent wood pieces  18  in each column are spaced from one another. The wood pieces  18  are preferably vertically oriented, such that the first end  34  of the wood pieces  18  lies generally adjacent the top surface  20  of the cardboard box  12 , and the second end  36  of the wood pieces  18  lies generally adjacent the bottom surface  22  of the cardboard box  12 . The shredded paper  16  fills the remainder of the container interior  14  completely surrounding each of the wood pieces  18 . It should be understood that the orientation shown in FIG. 1 is a preferred embodiment only, and the wood pieces  18  may be sized, dispersed and/or oriented in the container interior  14  randomly or in any other manner without departing from the spirit and scope of the present invention. 
     As shown in FIGS. 1 and 4, the shredded paper  16  defines pores  38  which are formed between, and by, the paper material. The pores  38  permit air to flow between the paper material, thus providing oxygen to the fire started and burning within the container interior  14 . 
     In operation, a user simply opens the flaps  26  of the top surface  20  to the position shown in FIG.  1 . Since the shredded paper  16  is a highly flammable material having a low burning point, upon touching a match or other lighting element to the shredded paper  16  it will almost immediately begin to burn. The user may then close the flaps  26  to the position shown in FIG. 2, to prevent wind from blowing out the fire which has been started within the container interior  14 . Oxygen is provided to the fire started and burning in the container interior  14  via the air holes  30  formed in the side surfaces  24  and the pores  38  defined by the shredded paper  16 . As the shredded paper  16  within the container interior  14  catches fire, it burns all around each of the wood pieces  18 , eventually heating the wood pieces  18 , to a burning point such that the wood pieces  18 , will ignite and begin to burn. Since the cardboard box  12  is also burnable, it will also catch fire, typically before the wood pieces  18  and will help to ignite the wood pieces  18 . Thus, simply by touching a match to the shredded paper  16 , a user can have a small fire readily before them in a matter of minutes, with little or no clean-up since all of the material included in the fire starting assembly  10  is burnable. 
     The fire starting assembly  10  can be used in a variety of outdoor activities, such as, but not limited to, camping, fishing along a lake or stream, hunting, sledding, working outdoors, or any outdoor activity in general. Preferably, as shown in FIG. 2, the cardboard box  12  has a length 1 equal to 14″, a width w equal to 14″, and a height h equal to 12″. With this particular size, the fire starting assembly  10  may be easily transportable to a variety of outdoor locations. Also, as shown in FIG. 3, the wood pieces  18  preferably have a height h′ equal to 11.5″, a width w′ ranging from 0.5″-2.0″, and a length 1′ between 0.5″-2.0″. Preferably, the wood pieces  18  have a square 1′×w′ cross-section, however, the present invention is not limited thereto. It will be appreciated that the smaller cross-sectional wood pieces  18  will “catch” and burn faster, while the larger cross-sectional wood pieces  18 , will “catch” and burn at a slower rate. Since the wood pieces  18  will be standing upright in the cardboard box  12 , there is room to place shredded paper  16  both below and on top of the wood pieces  18  in the container interior  14 . It should be understood that the above-recited dimensions of the cardboard box  12  and the wood pieces  18  are for exemplary purposes only to provide a fire starting assembly that is sufficiently light-weight to be readily transportable; any dimensions may be utilized without departing from the spirit and scope of the present invention. 
     The size of the cardboard box  12  and the wood pieces  18  will dictate the number of wood pieces  18  that may be positioned within the container interior  14 . Sufficient shredded paper  16 , or other flammable material, should be positioned in the container interior  14  surrounding the wood pieces  18  such that sufficient heat will be generated by the burning of the shredded paper  16  to ignite the wood pieces  18 . Testing was performed on a number of samples made in accordance with the above-recited dimensions, and each time the fire and heat generated by the fire starting assembly  10  lasted approximately 35-40 minutes without adding wood to the fire. Thus, the fire starting assembly  10  according to the present invention acts as a campfire in and of itself generating sufficient heat to temporarily warm individuals from the cold. Once the fire starting assembly  10  has been ignited and is readily burning, a user can easily add wood or other burnable material to the fire and keep it going for as long as it the user desires. 
     Virtually any type of wood, or combustible material, may be implemented for the wood pieces  18 , including, but not limited to, wood types such has pine, oak, cherry, poplar, maple, walnut, etc. Further, compressed particle board pieces may be utilized, and the wood pieces  18  may or may not include bark on the outer surfaces thereof. Still further, other combustible materials, such as, but not limited to, charcoal pieces, may be utilized in conjunction with, or in place of, the wood pieces  18  if so desired without departing from the spirit and scope of the present invention. 
     Similarly, any type of paper product or other flammable material having a sufficient burning point may be utilized in place of, or in conjunction with, the shredded paper  16  without departing from the spirit and scope of the present invention. For example, wood chips, saw dust, burnable wax-type material, etc., may be added to the shredded paper  16  for burning purposes. The only requirement being that the material utilized in place of the shredded paper  16  be easily ignitable in order to start the fire within the container interior  14 . Similarly, the wood pieces  18  may be provided with a flammable wax material to aid in the ignition process. Still further, a flammable accelerate may be provided in the container interior  14  to aid in ignition and burning. 
     If desired, advertising media may be printed on the side surfaces  24  of the cardboard box  12 , providing a non-exhaustive list of uses the fire starting assembly  10 , or simply for decorative purposes. 
     While the present invention has been described with particular reference to the drawings, it should be understood that various modifications could be made without departing from the spirit and scope of the present invention.
