Abstract: An apparatus for covering the lower rim of a metal can, where the rim has an outer face and an inner face and a bottom edge, includes a channel member having first and second side wall portions and a bottom wall portion connecting the first and second side wall portions, for fitting over the lower rim, such that the first side wall portion substantially covers the outer face, and the second side wall portion substantially covers the inner face, and the bottom wall portion substantially covers the bottom edge. The first side wall portion preferably has an inner first side wall surface, additionally including a lip portion extending from the inner first side wall surface toward the second side wall portion, for resiliently snapping over the rim and contracting above the rim to help hold the channel member securely on the can. Where the can has a can wall, the first side wall portion of the channel member optionally extends upward along the can wall above the rim for providing a surface for displaying a message.
