Abstract: A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.

Abstract: A molded plastic container includes a bottom wall to define a closed end of the container, a side wall extending generally axially away from the bottom wall, and a neck finish terminating the side wall to define an open end of the container. The neck finish includes a finish wall having an inner and outer surfaces. Also, the neck finish may include a seamless external thread segment projecting from the outer surface of the finish wall, and/or a flange extending radially outwardly from the finish wall and also extending axially downwardly and having a section thickness less than that of the finish wall, and/or a bead extending radially inwardly from the inner surface of the finish wall wherein the thickest section of any of the walls of the container extends through the bead.
