A novel box construction is provided having a numerous sealing features therein to provide a waterproof and sift resistant container. A first sealing feature is a pouring spout of three or four plies, the first and second plies of which provide a way for opening the spout. The construction of the spout also allows improved sealing because of its snap open and close feature. A second sealing feature uses transverse scoring of numerous panels and flaps with the scoring formed at the juncture between adjacent panels and flaps during manufacture and before assembly. A third sealing feature is the application of heat activated contact glue in several different patterns, including surrounding the spout with a glue border, applying "L"-shaped glue patterns on the perimeter of one panel, adding a glue border around almost the entire perimeter of one panel, and finally, applying glue on entire bottom panels and dust flaps.
