A closure arrangement for cans and pots comprising a tubular body (1) having a side wall (10) whose upper edge (10a) defines a seat for a lid (20). The upper edge (10a) comprises a peripheral annular flange (11) carrying, in a free outer edge, a continuous rib (12) with a cross-section contour comprising two opposite circle arc portions (12a), with curvature centers disposed in the same plane (P) orthogonal to the axis of the tubular body (1), the lid (20) being inferiorly provided with a continuous circumferential groove (24) to be seated against the respective circle arc portions (12a) of the continuous rib (12), so as to axially lock the lid (20) in the tubular body (10). An annular gasket (30) is carried by one of the parts of peripheral annular flange (11) and lid (20), to be pressed by the other of said parts upon closing the lid. ® KIPO & WIPO 2009
