Description

  The present invention relates to a combustible heat source, and more particularly to a solid fuel package that controls the continuous combustion of charcoal and other solid fuels and is completely combusted.

  Cooking outdoors is a popular recreational activity enjoyed by many in camping, day trips, picnics, tailgate parties at sporting events, and even in the backyard of your home. Gas grills and electric grills may be used at home backyards and even at tailgate parties. Many people prefer charcoal-grilling using charcoal and grills in order to cook savory, enjoy the smell and enjoy the act itself. When charcoal grilling, it is preferable that charcoal for cooking can be prepared quickly and easily. In addition, it is preferable to clean up after cooking, especially when cooking is performed outside the home.

  Charcoal briquettes are generally used to obtain the heat required for cooking and barbecuing using a grill. Conventional charcoal briquettes are usually contained in large bags, and when the charcoal briquettes are used, a small amount needs to be taken out from the bag and placed on the grill. Moreover, since it will become very dirty when using charcoal briquettes, it is desirable to avoid handling charcoal briquettes with bare hands as much as possible. Usually, a part of charcoal briquette is taken out from the bag, poured into a commercially available metal chimney starter, and ignited in the chimney starter. In order to ignite the charcoal briquette, a flammable liquid such as lighter oil may be used. When the charcoal briquette ignites and begins to burn sufficiently, turn the chimney starter over and pour the charcoal briquette over the grill. However, when using a metal chimney starter, the user carries a metal chimney starter and a charcoal briquette (usually about 20 pounds) filled in a bag and makes the charcoal briquette dirty when touched. You need to pour into a metal chimney starter, take the heated charcoal briquette out of the chimney, look for a safe place to put the hot metal chimney starter after removing the charcoal briquette, In addition, it was necessary to bring back a bag containing charcoal briquettes that were not used, and metal chimney starters that were used and soiled. For this reason, there is a need for a disposable chimney starter that is pre-filled with a predetermined amount of charcoal briquette and that can be completely burned.

The compartment 13 is large enough to accommodate a predetermined amount of charcoal briquette or other solid fuel. The cross-sectional shape of the main body 11 is preferably cylindrical, but those having a non-cylindrical shape such as a triangle, quadrangle, pentagon, hexagon, or octagon are also included in the scope of the present invention. In addition, the case where the main body 11 has not only a continuous tubular structure but also a structure in which a plurality of side walls are combined to form a partition is also included in the scope of the present invention.

  The body 11 is manufactured using cardboard, paperboard, paper tube, pulp paper, or other flammable materials known to those skilled in the art. These preferred materials have fire resistance that can sufficiently retain the structure of the body 11 until the solid fuel 12 burns to a sufficient degree to charcoal fire or cook the foodstuff, and the solid fuel It is preferable that the main body 11 is burned when 12 is burned to a sufficient extent and becomes ready for charcoal grilling.

  As shown in FIG. 8, the side wall 14 preferably includes a bottom lip 21 disposed at the lower end 16 of the main body 11. The bottom lip 21 is folded back with the lower end 16 of the main body 11 facing the inside of the section 13, and the lower end 16 is formed in a two-layered state so that the lower end 16 of the main body 11 has further thickness and strength.

  As shown in FIGS. 6 to 8, the main body 11 further includes a bottom cover 20 that forms an internal space 13 together with the side wall 14 and supports the solid fuel in the internal space 13. The bottom cover 20 can be manufactured using the same material as that of the main body 11, but is preferably manufactured from natural paper or a combustible material that can be used as an alternative. The bottom cover 20 is attached to the lower end 16 of the main body 11 by any means known to those skilled in the art. The bottom cover 20 is preferably provided with a flange 23 that is disposed between two layers of the main body 11 formed by the bottom lip 21 and is provided along the outer edge of the bottom cover 20. The attachment means for this purpose is not limited to these, but friction fitting, bonding, sewing, etc. using a joining material that completely burns together when the main body 11 and the solid fuel 12 burn. Means are included.

  In the manufacture of the fuel package 10, when the main body 11 including the bottom cover 20 is completely assembled, a predetermined amount of charcoal briquettes, or wood pellets, combustible compressed material pellets, and other known solid fuel 12 are divided into compartments 13. Is placed inside.

The ventilation system 22 provides the oxygen necessary for ignition and combustion of the solid fuel 12. The ventilation system 22 includes a plurality of ventilation holes 24 that are vertically disposed on the outer peripheral surface of the side wall 14 and are provided in a state of being substantially parallel to each other. The ventilation hole 24 includes an upper end 26 provided at an end closest to the upper end 18 of the main body 11 and a lower end 28 provided at an end closest to the lower end 16 of the main body 11. The ventilation holes 24 each have a width V _W and a length V _L.

In order for the body to ensure sufficient strength and fireproof performance to withstand combustion until the solid fuel 12 reaches the desired condition for charcoal firing, the ventilation holes 24 are preferably about 2-3. They are spaced 5 inches (about 5-9 cm) apart, more preferably about 2.5-3 inches (about 6.3-7.6 cm) apart from each other, although other spacings can be employed. Further, according to the diameter P _D of the body is increased until the solid fuel 12 reaches a state that can be used for grilled, maintaining adequate structure for supporting the solid fuel 12, and integrally necessary for structural body 11 A ventilation hole 24 for providing sufficient ventilation for igniting the solid fuel 12 may be further added to the main body 11 as long as the characteristics can be maintained. For example, the body 11 has a diameter P _D of about 4 inches (about 10 cm), preferably comprises a four ventilating hole 24. Further, the body 11 has a diameter P _D of about 6 inches (about 15cm), it is preferably provided with seven ventilation holes 24.

The area of the ventilation hole 24 is preferably about 4 to 12%, more preferably about 4 to 10%, still more preferably about 7 of the surface area of the main body assuming that no ventilation hole is provided. -8%. The width V _W of the ventilation hole is preferably about 0.2 to 0.3 inch (about 0.5 to 0.8 cm), more preferably about 0.25 inch (about 0.6 cm). preferable. However, the width V _W of the ventilation hole can be changed in accordance with the flammability of the material used for the main body 11, and similarly to the specific type and thickness of the material used for the main body 11. It can also be changed. Further, the length V _L of the ventilation hole is preferably about 0.5 inch (about 1.3 cm) smaller than the height of the side wall 14, but the difference between the length V _L depends on the type of paper used for the main body 11. It can vary between 0.42 and 2 inches (about 1 to 5 cm), and can be even more drastically when materials other than paper are used. If the distance between the upper end 26 of the ventilation hole and the upper end 18 of the main body 11 is too small, the main body 11 may collapse before the solid fuel 12 reaches a desired state that can be used for charcoal grilling. . Conversely, if the distance between the upper end 26 of the ventilation hole and the upper end 18 of the main body 11 is too large, the main body 11 will not collapse even when the solid fuel 12 can be used, or the main body 11 will burn completely. It may not be done. The distance between the ventilation hole 24 and the upper end 18 of the main body 11 is substantially equal to the distance between the ventilation hole 24 and the lower end 16 of the main body 11. As the combustibility of the material constituting the main body increases, the ventilation rate for the surface area of the entire main body 11 is adjusted so as to ensure the structure of the main body until the solid fuel reaches a desired state by adjusting the burning rate. It is preferable to reduce the overall size.

  The shape of both ends of the ventilation hole 24 may be curved or square as long as the manufacturing is easy and feasible, and other shapes that can be manufactured by those skilled in the art can also be adopted. In order to facilitate manufacture, the shape of the ventilation hole 24 is preferably a vertically long slit as shown in FIGS. However, in determining the appropriate number and size of ventilation holes to be formed in the main body 11, as long as it is considered to increase the area of the ventilation holes, oval, ellipse and other shapes are adopted. It is also included in the scope of the present invention. Further, instead of a single continuous ventilation hole, a ventilation hole constituted by arranging a plurality of short through holes in a line in the vertical direction is also included in the scope of the present invention.

  A roll lip (not shown) may optionally be provided at the end of the side wall 14 on the upper end 18 side in order to provide an additional structure for attaching an optional lid 30 and an additional surface area. Good. In one embodiment of the present invention, a lid 30 that covers the upper end 18 of the main body is provided to prevent the solid fuel 12 from jumping out of the compartment 13 during carrying. The lid 30 is manufactured using plastic, paper, or other materials (such as aluminum foil). The lid 30 can be removably attached to the body 11 by friction fit, gluing (see FIG. 4), packaging (package), or other means known to those skilled in the art. The lid 30 preferably has a shape that matches the shape of the upper end 18 of the main body or is provided with a plurality of corners and tabs protruding above the upper end 18 in order to facilitate removal.

  In use, the fuel package 10 is placed vertically in the grill unit with the lower end 16 down. The lid 30 is removed before and after placing the package 10 in the grill unit. The solid fuel 12 is ignited by a match or lighter through an upper opening 19 provided at the upper end 18 by the user. As the solid fuel 12 burns, the paper material of the main body 11 also burns. The ventilation hole 24 provides desired ventilation to the entire main body 11. As the solid fuel 12 and the main body 11 burn, the paper outer plate of the main body 11 burns down to the lower end 16, and the solid fuel collapses and becomes a uniform deposit. The solid fuel (preferably charcoal briquette) can be used for cooking when the main body 11 is completely burned. If necessary, a combustion accelerator may be added to the solid fuel. After cooking, only ash, which does not contain paper, metal, or other waste, remains, so the user can discard the ash.
