ABSTRACT:
A paperboard carton having a large capacity pouring spout formed in a relatively narrow end wall, the pouring spout being fabricated as the carton is tubed into knocked-down flat-folded condition, the carton having an opposing pair of side walls and an opposing pair of relatively narrow end walls, with a glue flap hingedly connected to the side edge of one of the side walls, the glue flap being juxtaposed and adhesively secured to the inner surface of the adjacent end wall to form a tubular carton body; an outwardly displaceable pouring spout tab is formed in the end wall to which the glue flap is juxtaposed, the pouring spout tab being of generally rectangular configuration and having one of its side edges lying along the line of articulation between the end wall and the other of the side walls, the underlying glue flap being enlarged to extend across the full width of the end wall in the area of the pouring spout tab, the enlarged portion of the glue flap having an extension hingedly connected to its outermost side edge which is juxtaposed to the innersurface of the other of the carton side walls; a pouring spout being formed in the enlarged portion of the glue flap and its extension, the pouring spout having a generally rectangular center member secured to the inner surface of the pouring spout tab in the end wall, and a pair of wing members hingedly connected to the opposite sides of the center member, one of the wings being struck from the enlarged portion of the glue flap on one side of the center member, and the other wing being struck from the extension which lies along the inner surface of the other side wall, the outward displacement of the pouring spout tab causing the spout members to be displaced outwardly with the wings bearing against the opposite sides of the opening defined by the displaced pouring spout tab, the wings providing full depth side walls for the spout.
