ABSTRACT:
This invention provides apparatus for securing a substantially flat lid closure member to an upwardly directed opening of a container partially surrounded by an outwardly directed substantially horizontal base flange means where a peripheral lip is provided around a portion of the outer edge of the base flange and includes a front lip, a rear lip and spaced apart side lips extending generally between the front lip and the rear lip and where the lid member is received within the lip means on the base flange to cover the container opening to retain a selected product within the container. The container is moved on conveyor means in a selected direction along a conveyor path. First side folder means are provided to fold the side lips over the lid. Orbital roller means are connected to shaft means above the conveyor path to rotate in an orbital path about pivot means at a selected speed so that at the bottom of the orbital path, the orbital roller moves in the direction of travel of the container to fold the rear lip inwardly. Roller means are located at substantially the same elevation as the base flange where the container is then passed under the roller means to fold the front lip down onto the lid means.
