Box spout

A pouring spout attachable to a vertical side wall of a box formed of cardboard or the like for discharging the box contents, characterized in that:

• (a) said spout has a pair of spaced apart walls including an inner wall and an outer wall which are integrally joined at their upper ends, and the spout is open on the upper end and along the rear side thereof;
• (b) the inner wall is longer than the outer wall and it is provided with longitudinal converging marginal cutting edges which terminate in a cutting point at the lower end thereof;
• (c) a longitudinal central cutting edge is formed on the outer surface of the inner wall;
• (d) the inner and outer walls extend forwardly in plan cross section;
• (e) the longitudinal edges of the outer wall converge toward its lower end;
• (f) a plurality of spaced apart longitudinal ribs are mounted on the outer surface of the inner wall;
• and,
• (g) the outer wall is disposed in a position diverging downwardly and outwardly from the inner wall, whereby when the cutting point on the spout inner wall is inserted into a vertical side wall of a box in a position perpendicular thereto, and the spout inner wall is moved inwardly into the box until the spout outer wall engages said box wall, a substantial horizontal cut is made in said box wall and a vertical, downwardly extending cut that communicates with the horizontal cut is made in said box wall and the forwardly extended inner wall folds inwardly the lower edge portions of said box wall, along the horizontal cut and on each side of the vertical cut, and then the spout is pivoted upwardly into an abutting relationship with the box wall and said lower edge portions of the box wall are then moved longitudinally between said spout walls, and wedges therebetween by said longitudinal ribs, when the spout is next moved downwardly relative to the box wall.
