ABSTRACT:
An open-topped container has an outwardly turned rim extending around the open top a thermoformed body of the containers with the rim formed by a clamping ring which has one or more projections each forming an indentation into the rim. Trim tooling subsequently forms a slit through the bottom wall of each indentation able to receive a flat plastic display inserted therein.
