A carton pour spout adjoining the juncture of two carton panels foldably connected along a common fold line, the spout including: a pair of upwardly curved and outwardly bowed similar fold lines extending from a common point on said common fold line to points equally spaced on opposite sides of said common fold line, weakened lines of separation extending upwardly from said equally spaced points to a second common point on said common fold line spaced from said first named common point, a pair of fold lines extending in V-shaped relation from said equally spaced points downwardly to a third common point on said common fold line, said third common point being between said first and second common points, and whereby when inward pressure is exerted to said fold line between said first common point and said third common point, the area between said outwardly bowed fold lines will fold inwardly along said curved outwardly bowed fold lines, a pair of reinforcing panels secured inwardly of said carton panels, said reinforcing panels having a fold line coinciding with said common fold line, said reinforcing panels having an aperture defined by lower edges which substantially concide with said outwardly bowed fold lines, and by upper edges spaced inwardly offset relating to said weakened lines so as to reinforce the edge of the area defined by said weakened lines of separation said upper edges remaining in the plane of the reinforcing panels in which they are located to form an abutment against which the areas of said panels adjoining said weakened lines may engage in face contact, and including a second aperture a slot in said reinforcing panels intersecting the fold line between said reinforcing panels and interrupting said last named fold lines to provide narrow connecting straps between said reinforcing panels.
