Abstract
A coated paperboard container and a blank for constructing the container are disclosed as including a body portion having an upper end that is closed by a folded top end closure which includes closure panels having a construction that enhances foldability and sealing. Front and back gable panels of the top end closure are each flanked by a pair of triangular inner roof panels that have different sizes than each other so as to facilitate folding of the sealed top end closure from a vertical position in a direction toward the smaller inner roof panels. The unequal size of the inner roof panels on opposite sides of each gable panel is provided by score line portions that are stepped with respect to one another. The lower of the adjacent score line portions, providing the smaller inner roof panel is formed wider than the other score lines so as to allow the top seal to be sealed in a vertical position and then to be readily folded toward the smaller inner roof panels.
