1. A package for abrasive wheels, the package comprising:
a base providing an inner space between a side surface, an open end having a diameter Dopen and a closing plane end having a diameter Dclosed, the inner space being adapted to contain stacked abrasive wheels having a diameter Dwheel, the side surface having a projecting portion having a diameter Dproj, that projects from the closing plane end; and
a cover configured to couple to the base at the open end so as to close the inner space, the base and the cover insulating the abrasive wheels against atmospheric agents when coupled, the cover comprising a projection shaped to define an annular plane portion having an inner diameter Din and an outer diameter Dout,
wherein Dwheel≤Din<Dproj≤Dclosed<Dopen≤Dout,
and wherein the side surface comprises a base portion, an annular base belt portion and an edge portion, wherein:
the base portion extends from the closing plane end to a first end of the annular base belt portion, and the edge portion extends from a second end of the annular base belt portion to the open end; and
the annular base belt portion protrudes away from the side surface thereby defining a shoulder between an outer surface of the annular base belt portion and the edge portion,
wherein the base portion is a frustoconical base portion having a first diameter corresponding to Dclosed at the closing plane end of the base and a second diameter Dbelt at the first end of the annular base belt portion, wherein Dclosed<Dbelt; and
wherein the edge portion is a cylindrical or frustoconical edge portion having a first diameter corresponding to Dbelt at the second end of the annular base belt portion and a second diameter corresponding to Dopen at the open end of the base, wherein Dbelt>Dopen.
