Description
- This application is a continuation-in-part of pending U.S. application Ser. No. 29/208,910 filed Jul. 7, 2004 which is incorporated herein.
- This invention relates to the field of charcoal briquets and other solid fuel compositions. More particularly, the present invention relates to pillow-shaped charcoal briquets having improved surface features that aid in improved random stacking, lighting and burn phase characteristics.
- There is great consumer interest in using charcoal for outdoor cooking in which meals can be prepared and served quickly for individual or large group consumption. Consumers desire cooking and grilling with charcoal briquets that are easily stackable to form the traditional starter pile, easily ignitable, maintain a uniform and efficient combustion that ignites the individual briquets in the starter pile, and have a sufficiently long burn period. Similarly, consumers desire to handle dirty charcoal as little as possible when forming traditional starter piles and the like.
- Charcoal briquettes are often configured in a generally pillow-shape. This configuration provides for both reasonable ease of manufacturing by the supplier, and handling by the consumer. Pillow-shaped briquets are typically used for cooking on the grill or the like by using a multiplicity of briquets in a mounded or conical configuration or stack usually by pouring a multiplicity of briquets from a bag onto a grill or the like. then lighter fluid is often added, and followed by igniting the briquets with an ignition source.
- An “ignition phase” follows, as burning proceeds from the surface of the briquet, and a gray ash is formed on a significant portion of the briquet until a majority of the exposed surfaces have ignited, and burning has progressed inwardly toward the intended area of the briquets. Thus, completion of the ignition phase of burning is identified by the formation of visible ash on the briquet.
- At this point, the briquets are spread out under the grill or the like, and they continue to burn with intense heat suitable for cooking and grilling throughout a “burn phase”. For maximum performance of the briquets, it is desirable that the ignition phase be limited in time so that the briquets may be used for cooking or grilling without undue delay, such that the duration of the burn phase is optimized and extended to provide adequate cooking or grilling time as desired by the consumer intended use.
- There has been some previous work in the ornamental and geometrical configuration of charcoal briquets. For example, U.S. Des. 389,453 to Mitchell et al. describes a charcoal briquet having a groove generally in the shape of the letter “K”, and U.S. Pat. No. 4,496,366 to Peters describes charcoal having a briquet, or other geometric configuration, purportedly to achieve desired lighting and burn characteristics. In another example, U.S. Pat. No. 6,074,446 to Fujino describes charcoal having a plurality of air passing portions or grooves in its body purportedly to supply combustion air inside the charcoal body while burning.
- However, previously known ornamental and geometrically configured charcoal briquets fail to address enhancing the surface of pillow-shaped briquets to improve the random, non-mating stacking ability properties, as well as to improve ignition and burn phase characteristics. Particularly charcoal briquets used for home grilling and cooking, wherein the consumer desires charcoal briquets that require less handling, and that can be readily ignited to provide maximum heat initially, followed by an improved burn phase.
- Previously known charcoal briquets intended for rapid ignition and delivery of intense heat have used combinations of various configurations and compositions. However, very rapid delivery of intense heat does not provide an acceptable combustion response for cooking or grilling purposes. Previous teachings have failed to configure and texture the surface of a pillow-shaped charcoal briquet to improve random stacking ability of the briquet, as well as enhance the ignition and burn phase properties of the briquet as preferred by consumers.
- In accordance with the present invention, an improved charcoal briquet having a generally pillow-shaped configuration having an upper surface, a lower surface, a periphery, and enhanced surface features preferably comprising one or more grooves, channels, trenches or the like, on one or both surfaces. The improved charcoal briquets of the present invention have improved random stacking ability, and enhanced ignition and burn phase properties, thereby overcoming previously known difficulties.
- More specifically, and in accordance with the present invention, an improved pillow-shaped charcoal briquet having a generally convex upper surface, a generally convex lower surface, and a periphery wherein at least one of the upper or lower surfaces has located thereon enhanced surface textured features in the form of at least one groove, channel, trench or the like. When two or more grooves are present on one or both surfaces, the grooves are preferably parallel to each other, parallel to two opposing sides of the briquet, and perpendicular to two other opposing sides of the briquet. The presence of one or more grooves on or both surfaces increases the surface area to volume ratio thereby enabling more of the briquet to be exposed to oxygen.
- These and other objects and advantages are achieved by the present invention which comprises a generally pillow-shaped charcoal briquet having an improved surface configuration. Pillow-shaped charcoal briquets having this unique surface configuration have enhanced ignition properties and burn phase characteristics.
- These and other objects and advantages of the present invention will become apparent from the following description of the preferred embodiments of the invention, taken together with the accompanying drawings.
