Abstract
A device for extinguishing a cigarette without damaging the cigarette thereby allowing the cigarette to be relit for continued smoking without the bad taste normally accompanying a relit cigarette includes an air compartment with an entrance into the compartment through which the lighted end of a cigarette is inserted. The compartment is configured so that upon insertion of the cigarette, a substantially closed air chamber is formed communicating with the end of the cigarette. The cigarette itself substantially blocks the entrance to the air chamber so that air flow into the chamber, other than through the cigarette itself, is substantially blocked. The air chamber is sized to provide enough air to support continued burning of the cigarette for a preset time, usually about five seconds, after insertion. The invention also includes a device for allowing the cigarette to continue to burn between drags on the cigarette but to reduce the smoke output and rate of burn. This includes a channel shaped to closely receive and cradle the burning end of a cigarette around at least a third of the circumference of the cigarette. An ash tray of the invention preferably includes both devices of the invention.
