ABSTRACT:
A non-cylindrical container having sidewalls joined together by rounded corners is provided with an improved closure apparatus for more uniformly distributing closure forces around the periphery of the container and lid interface. The closure apparatus is formed from two bands which each consist of two leg portions joined by an included corner. The bands are selectively fastened together by a fastening means at their terminal ends which correspond to opposite rounded corners of the rectangular container. The leg portions of the bands may be inwardly concave allowing the sidewalls of the container to be preloaded in order to more uniformly distribute closure forces among the sidewalls and corners.
