Abstract
The present invention includes an injection molded lid comprising a closed annular rim, a skirt fixed to and extending downwardly from the rim and a film sealed to the bottom side of the rim to cover the open space within the rim. The rim and skirt are molded as a single monolithic lid preform, with the skirt being fixed near the outer peripheral edge of the rim. The film is sealed along the inner peripheral edge on the bottom side of the rim. This device allows for a prospective consumer to view the contents of the container before purchasing it. In addition to the lid device, a method is provided of forming a closure to seal a food container. A lid preform is injection molded as a monolithic unit comprising a skirt and a closed rim. Then the film is sealed along the entire length of the inner peripheral edge on the bottom side of the rim. This method allows for forming a sturdy closure capable of maintaining the integrity of its original seal with the container as well as its seal with the film.
