摘要： Two portions (10, 12) are injection molded and ultrasonically welded together to form a plastic container (C) defining a hollow interior (16) for containing food products and having an open top sealed by a thin, flexible, foil seal member (14). The container (C) has an inwardly projecting lip (38) which is arched shaped including an outer annular portion (86) extending inward and upward from the sidewall (24) of the container (C) away from the hollow interior (16) of the container (C) and including an inner annular portion (92) radially inward of the outer annular portion (86) and having an outer face (92a) extending downward towards the hollow interior (16) of the container (C). The upper surface of the lip (38) is continuous, smooth and free of steps and ridges to present a continuous seal area for the foil seal member (14) independent of the deflection of the lip (38) into the hollow interior (16) of the container (C).
