The sheet material is preferably of light-gauge sheet aluminum formed into an open-topped, cup-like ashtray liner having opposed end walls and opposed side walls and including an upper end plate secured against the upper periphery of the liner providing an outwardly-extending peripheral flange. The upper end plate has a pair of spaced, parallel, rectangular openings defining therebetween a snuffer strip extending between opposite end walls of the liner.
