Abstract
A stackable ashtray, which is essentially characterized as a truncated pyramid shaped body of very low height and internally recessed, in whose upper horizontal side, concentrically presents the circular contour of a concave depression of the spherical cap that surrounds its lower surface a bead of configuration in trunk of inverted cone, descending until a level inferior to the one of the edges of the external pyramidal walls, constituting said bead, in the base plane of sustentation and giving rise to the concavity created internally, to the capacity of penetration for the superior coronary surface of another analogous unit introduced in the stacking regime.
