Abstract

A closure arrangement for cans and pots comprising a tubular body having a side wall whose upper edge defines a seat for a lid. The upper edge comprises a peripheral annular flange carrying, in a free outer edge, a continuous rib with a cross-section contour comprising two opposite circle arc portions, with curvature centers disposed in the same plane orthogonal to the axis of the tubular body, the lid being inferiorly provided with a continuous circumferential groove to be seated against the respective circle arc portions of the continuous rib, so as to axially lock the lid in the tubular body. An annular gasket is carried by one of the parts of peripheral annular flange and lid, to be pressed by the other of said parts upon closing the lid.
