Carton with pouring spout
First Claim
1. In a unitary carton blank adapted to be erected into a carton having a reclosable pouring spout, said blank having a pair of spaced main panels, a first end panel disposed between said main panels and separated therefrom by a pair of first fold lines defining the opposite edges of the end panel and one edge of each of the main panels, a second end panel hingedly connected along the other edge of one of said main panels, a top end closure panel disposed along the top edge of each of said main panels and separated therefrom by a second fold line, a bottom end closure panel hingedly connected along the bottom edge of each of said main panels, a diagonal fold line on each main panel extending between the first fold line and the second fold in the upper corner adjacent the first end panel, each of said top end closure panels terminating at the intersection of the adjacent diagonal fold line with the second fold line, and the first end panel extending higher than the top edges of the main panels and defining an upper section above the intersection of the diagonal fold lines with the first pair of fold lines whereby said blank when erected forms a carton with a diagonally angled upper corner panel recessed between the main panels and under the top closure panels for opening into a pouring spout, the improvement comprising:
- a. a central score line formed in the upper section of the end side panel between the opposite edges thereof; and
b. a pair of spout forming score lines extending from the opposite ends of the central score line to the diagonal fold lines intermediate their ends.

Abstract
A carton with a reclosable pouring spout formed from a unitary carton blank. The carton blank is provided with appropriate fold lines to permit erecting into a carton having a diagonally angled upper corner panel recessed under the top and between the sides of the carton. The carton blank is provided with score lines positioned so as to extend across the upper corner panel of the completed carton. The carton is adapted to be broken along the score lines and the underlying section of the corner panel pulled outwardly to form a pour spout.

3. In a unitary carton blank adapted to be erected into a carton having a reclosable pouring spout, said blank having a pair of spaced main panels, a first end disposed between said main panels and separated therefrom by a pair of first fold lines defining the opposite edges of the end panel and one edge of each of the main panels, a second end panel hingedly connected along the other edge of one of said main panels, a top end closure panel disposed along the top edge of each of said main panels and separated therefrom by a second fold line, a bottom end closure panel hingedly connected along the bottom edge of each of said main panels, a diagonal fold line on each main panel extending between the first fold line and the second fold in the upper corner adjacent the first end panel, each of said top end closure panels terminating at the intersection of the adjacent diagonal fold line with the second fold line, and the first end panel extending higher than the top edges of the main panels and defining an upper section above the intersection of the diagonal fold lines with the first pair of fold lines whereby said blank when erected forms a carton with a diagonally angled upper corner panel recessed between the main panels and under the top closure panels for opening into a pouring spout, the improvement comprising:
-
a. a central score line formed in the upper section of the end side panel between the opposite edges thereof; b. a pair of spout forming score lines extending from the opposite ends of the central score line to the diagonal fold lines intermediate their ends; c. a pair of tab forming score lines, each of which extends from adjacent one end of the central score line and in a direction toward but spaced from the top edge of the upper section of the first end panel; and d. a tab forming fold line extending between the uppermost ends of the tab - View Dependent Claims (4, 5, 6, 7)
