An assembly for forming a container that contains food product and including a thermoformed sleeve and a base. The sleeve includes a frustoconical side wall, an upper lip, and a lower lip. The side wall defines an inner surface, an outer surface, and a plurality of circumferentially-spaced handling features including an outer surface indentation and a corresponding inner surface protrusion. The upper lip projects generally radially inwardly from an upper end of the sleeve and the lower lip projects generally radially outwardly from the lower end. The base is formed apart from the sleeve, and is assembleable to the lower end for closing off the lower opening. In some embodiments, each of the plurality of handling features are wedge-shaped. In yet other embodiments, the base is a thermoformed part, and is ultrasonically welded to the lower lip.
