ABSTRACT:
A nesting rim member mountable in circumscribing composite relation to the stacking end of a walled container. The rim includes an outer vertical flange portion which tapers inward from an upper edge to a nesting ledge. An inverted U-shaped channel portion beneath the nesting ledge extends over the container sidewalls which are recessed at their corners to receive pronged corner clips, if necessary. Each clip mates with the rim member when pressed onto the container walls. A U-shaped channel orthogonally projects inward of the container. The rim member may be extruded and pieced to the container walls or molded as a continuous ring.
