Abstract
Abstract An improved container for storing frozen foods such as ice cream comprising a base, a cylindrical body member joined to the base, and a rim disposed on the end of the body member which includes an edge projecting radially outwardly therefrom perpendicular to the longitudinal axis of the container. A cover adapted for slidable positioning over the rim has spaced-apart annular ridges on the inner surface thereof between which the edge of the rim is received for securing the cover on the body member.
