An openable securing ring for holding a lid or similar closure on a container has a latch mechanism arranged to secure ends of the ring releasably together at a circumferential break. A circumferentially extending recess is provided at a radially inner portion of the latch mechanism so that the radially inner portion is of reduced axial external thickness and provides relief for stable stacking of a first container on top of a second container when the securing ring is attached to the second container. A radially inner edge of a locking lever side wall may lie radially outward of the inner diameter of one ring end to define at least part of the reduced thickness radially inner portion.

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, anda 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: an elongate top wall which, when the lever is in the generally tangential position, lies radially outward of at least one of the secured pair of ring ends, anda pair of opposed side walls, co-extensive with the top wall and lying axially to either side of one secured ring end, to form, together with the top wall, a channel in which the one secured ring end is at least partially received;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; anda 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. 2. The securing ring of claim 1, wherein the securing ring is made of a plastic. 3. The securing ring of claim 1, wherein the securing ring comprises a main part having a profile which is extended into said other of the pair of ring ends between said further walls. 4. The securing ring of claim 1, wherein the securing ring and the releasable fastening or latch mechanism are substantially symmetrical in cross-sectional profile, whereby the securing ring is configured to be mounted to the container or container lid either way up. 5. A securing ring for holding a lid or other closure on a container, the securing ring having an inner diameter and comprising: a circumferential discontinuity which forms a pair of ring ends; anda lever comprising a lever side wall, the lever being movable between a generally radially extending position where the pair of ring ends are held in a released condition, and a generally tangential position where the pair of ring ends are held secured together,wherein the lever side wall comprises a radially inner edge which lies radially outward of the inner diameter of the securing ring with the lever in the generally tangential position,wherein an outer one of the pair of ring ends comprises an outer end side wall lying outwardly of the lever side wall in an axial direction of the securing ring, andwherein the outer end side wall comprises a radially inner edge which lies radially outward of the inner diameter of the securing ring. 6. The securing ring of claim 5, wherein the 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. 7. The securing ring of claim 5, wherein the lever comprises: an elongate top wall which, when the lever is in the generally tangential position, lies radially outward of at least one of the secured pair of ring ends, anda second side wall, the side wall and second side wall being co-extensive with the top wall and lying axially to either side of one secured ring end, to form, together with the top wall, a channel in which the one secured ring end is at least partially received. 8. The securing ring of claim 6, wherein: the outer ring end comprises an opposed pair of outer end side walls lying axially to either side of the securing ring and between which the lever is mounted by the second pivotable connection, andwhen the lever is in the generally tangential position, a radially inner edge of at least one of the outer end side walls lies at least as far radially outward as the lever side wall radially inner edge. 9. The securing ring of claim 8, wherein the securing ring comprises a main part having a profile which is extended into said outer ring end between said opposed pair of outer end side walls. 10. The securing ring of claim 5, wherein the securing ring and the lever are substantially symmetrical in cross-sectional profile, whereby the securing ring is configured to be mounted to the container or container closure either way up. 11. The securing ring of claim 5, wherein the lever comprises an opposing side wall comprising a radially inner edge which lies radially outward of the inner diameter of the securing ring. 12. The securing ring of claim 11, wherein: said outer ring end comprises an opposing side wall lying outwardly of the lever opposing side wall axially of the securing ring; andsaid opposing side wall of the outer ring end comprises a radially inner edge which lies radially outward of the inner diameter of the securing ring. 13. The securing ring of claim 5, wherein the securing ring is made of a plastic.
