Abstract: A knocked-down easily-assembled sterilizing rack for holding conventional disk-shaped lids used for sealing mason jars. A sheet-metal inverted-trough-shaped body has a plurality of parallel transaxial slots to hold the lids upright and spaced. An initially unattached bail-shaped handle is dimensioned to embrace the sides and an end of the body for parts-protecting and for economical compact shipping-packaging. The handle and the body have snap-together assembling detent elements.
