Abstract:
1. A ring for maintaining the closure of a cylindrical container, the cylindrical container including a rim flange attached to the upper end of the container around the circumference of the container and extending radially inwardly therefrom, said rim flange defining an annular locking channel depending downwardly from the rim flange for receiving an annular channel of a container lid adapted to fit within the locking channel for sealing engagement between the lid and container, the lid having an annular ridge extending upwardly from the lid, the ring comprising: an annular body; an annular outer limb depending downwardly from the body; an annular locking finger extending radially inwardly from the outer limb; an annular inner limb depending downwardly from the body; and an annular flange extending in a radially-inward direction from the inner limb, the annular flange having an axial thickness greater than a thickness of the annular body, the axial thickness being uniform along the radially-inward direction; whereby when in use the ring engages the cylindrical container such that the annular locking finger engages an outer circumference of the rim flange, the annular inner limb depends into the annular channel, and the annular flange contacts the lid at the annular ridge of the lid radially inwardly of the annular channel of the lid to maintain closure between the container and lid.
