ABSTRACT:
A unitary, removable, transportation ring for maintaining the closure of a covered container, such as a cylindrical paint can, snaps into place and securely maintains a lid on the container even in an environment of high pressure within the container. The ring is responsively operable in the presence of elevated and extreme pressures within the container to improve the engagement of the ring with the container, and to improve the engagement of the lid with the container, each in order to maintain the cover tightly sealed over the top opening of the container. An annular flange depends from the inner radial margin of the body of the ring and abuts the lid or cover of the container to maintain the engagement of the lid with the container.
