ABSTRACT:
A system for removing and disposing of smoke and residues produced by cigarettes or the like includes an ashtray unit adapted to be received by a valved receptacle in a tabletop or the like. The ashtray unit has a cigarette-holding portion and a passage connected to a residue-receiving canister adapted to be coupled to a vacuum source. A valve is disposed in the ashtray unit passage. In one embodiment, the valve is biased to a normally open position. In another embodiment, the valve is biased to a normally closed position. In the latter case, the ashtray unit includes a plurality of small passageways connecting the cigarette-holding portion with the passage, the passageways bypassing the normally closed valve.
