Claim Text:
1. A rim cover assembly comprising an outer rim cover for a first size can, and an inner rim cover for a second size can smaller than the first size can, the outer rim cover and the inner rim cover being concentric, and the outer rim cover being coupled to the inner rim cover by a plurality of severable couplings, each of the inner rim cover and the outer rim cover comprising: an annular cover with a top surface, a bottom surface opposite the top surface, an outer periphery, an inner periphery, a major diameter at the outer periphery, a minor diameter at the inner periphery, and an annular cover thickness measured from the top surface of the annular cover to the bottom surface of the annular cover; an outer wall forming an outer cylinder having an outer diameter and extending from the bottom surface of the annular cover and having a free end, an outer side, an inner side, an outer wall length defined by a distance from the bottom surface of the annular cover to the free end of the outer wall, and an outer fin extending radially from the inner side of the outer wall adjacent to the free end of the outer wall; an inner wall forming an inner cylinder having an inner diameter and extending from the bottom surface of the annular cover and having a free end an outer side, an inner side, an inner wall length defined by a distance from the bottom surface of the annular cover to the free end of the inner wall, and an inner fin extending radially from the outer side of the inner wall adjacent to the free end of the inner wall, opposite to and towards the outer fin; a plug forming an intermediate cylinder having an intermediate diameter and extending from the bottom surface of the annular cover and having a free end, an outer side and an inner side, a plug length defined by a distance from the bottom surface of the annular cover to the free end of the plug, a plug width defined by a distance from the outer side to the inner side, the plug being between the inner cylinder and the outer cylinder; the inner diameter being less than the rim inner diameter, less than the major diameter, less than the outer diameter, less than the intermediate diameter, and at least as great as the minor diameter; the outer diameter being greater than the minor diameter, greater than the inner diameter, greater than the intermediate diameter, greater than the rim outer diameter, and not greater than the major diameter; the intermediate diameter being between the inner diameter and the outer diameter, and about equal to the groove diameter; and the annular ring, inner cylinder, intermediate cylinder, and outer cylinder being concentric; the plug length, inner wall length and outer wall length being about equal, and the plug length being about equal to the groove depth and the plug width being about equal to the groove width.
