Abstract
Reusable charcoal chimney devices and inserts which may allow for faster lighting of charcoal material, without any need for lighter fluid. The charcoal chimney device may include a charcoal container including a bottom end, a top end, and a sidewall disposed there between. The charcoal container includes an internal cavity for containing charcoal. The charcoal container may be formed of a non-combustible material so that it can be reused, and is not consumed during use. An elongate insert is disposable within the internal cavity of the charcoal container for forming a hollow flue from a bottom of the internal cavity to the open top end of the charcoal container when charcoal is loaded into the internal cavity around the insert. The hollow flue defining portion of the insert may occupy a minimal fraction of the volume of the internal cavity to limit volume that can no longer be occupied by charcoal.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
