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