Abstract

Abstract A low cost smokeless ashtray includes an upper, generally cylindrical receptacle having a bottom panel with a pair of selectively closeable apertures. Extending downwardly from the center of the bottom panel is a unitary journal having a radially projecting key. The receptacle is rotatably mounted to a base with the journal extending through a keyed orifice. The base includes an upper planar bearing plate having a pair of butt receiving wells. The wells are accessed by rotating the receptacle relative to the base until the bottom panel apertures are registered with the wells. The receptacle and base are each preferably molded in one piece construction of a suitable thermosetting polymer such as an amino resin, for example, a melamine molding compound with an alpha cellulose filler.
