Claim:
1. A securing ring for holding a lid or other closure on a container, the securing ring comprising: a circumferential discontinuity which forms a pair of ring ends, and a releasable fastening or latch mechanism configured to secure the pair of ring ends releasably together, the releasable fastening or latch mechanism and the pair of ring ends comprising respective radially aligned inner portions, wherein: the releasable fastening or latch mechanism comprises a lever joined to one of the pair of ring ends by a first pivotable connection and to the other of the pair of ring ends by a second pivotable connection; the lever is movable between a generally radially extending position where the pair of ring ends are in a released condition, and a generally tangential position where the pair of ring ends are secured together; the lever comprises: when the lever is in the generally tangential position, a radially inner edge of at least one of the side walls lies radially outward of an inner diameter of the secured one ring end to define one of the radially aligned inner portions of reduced axial external thickness; the other of the secured pair of ring ends comprises an opposed pair of further walls lying axially to either side of the securing ring and between which the lever is mounted by the second pivotable connection; when the lever is in the generally tangential position, a radially inner edge of at least one of the further walls lies at least as far radially outward as the at least one lever side wall radially inner edge, to define another of the radially aligned inner portions of reduced axial external thickness; and a recess is provided at the radially aligned inner portions and throughout an entire circumferential extent of the releasable fastening or latch mechanism and the pair of ring ends such that the radially aligned inner portions are of reduced axial external thickness relative to a radially outer portion of the releasable fastening or latch mechanism and the pair of ring ends, and provide relief for stable stacking of a first container on top of a second container when the securing ring is attached to the second container.
