Box with widest possible pouring spout

Abstract

The present invention is directed to a box with the widest possible pouring spout. The spout is an integrated portion of the box with no additional or external portions required for manufacture. The spout has a means by which a person using the spout may conveniently open the spout, a means by which the spout will be secured from opening beyond the position required for maintaining the spout pouring area and a means by which the spout will be secured in a closed position when not in use. Because the spout is an integrated portion of the box, the box with widest possible pouring spout will be efficient and economical to produce and will provide the largest possible pouring area for large, bulky or cumbersome products.
