The device comprises an open-topped receptacle having a support adapted to receive and hold a lit tobacco product. Air for supporting combustion of the tobacco product will enter vent means in the lower base member. The receiver has a closure member for the upper portion of the opentopped receptacle. Said closure member conforms in size and shape to the lower base member and is hinged to said lower base member. Said members have cooperating members to hold the closure in a closed position. The receptacle includes liners for absorbing smoke produced by the product and thusly limit the amount of smoke which may pass out of a vent in a vertical wall of the lower base and closure member.
